Full textAbstract:
In this study, a parametric model for a main battle tank electric gun turret drive system
stabilization controller has been developed. Main scope was the study of the muzzle deviation
due to barrel flexibility. Traverse and elevation dynamics has been modeled to include the
drive-line and barrel flexibilities. Order of the models has been kept large enough to cover the
frequencies dominant in the interest scope but at the same time low enough to create a
parametric model which can be used in real-time fire control computers. Therefore a 5-dof
elevation and a 7-dof traverse models have been implemented. These models have been used
to design a classical feedback and feedforward controllers which performed good enough to
meet 0.5mrad stabilization accuracies.
After satisfactory results have been obtained from the stabilization controller, a special
coincidence algorithm has been implemented by time-series analysis of the disturbance signal
which is constantly being measured by the feedforward gyro. Necessity of predicting the
future muzzle angular orientation due to the latency in fire is discussed and by using
autoregressive modeling of the disturbance signal, future values of the disturbance signal has
been entered into the observer model. The prediction horizon has been set to the time delay
value between the trigger is pulled by the gunner and the ammunition exit from the muzzle.
By checking the future coincidence within a very narrow windowing (0.05mrad) a 100% first
round hit probability in theory has been achieved. This is assured since the coincidence
inhibited the fire signals which were to miss the aiming point with a large error.

Диссертация на соискание ученой степени кандидата технических наук по специальности 05.13.03 – системы и процессы управления. – Национальный технический университет "Харьковский политехнический институт", Харьков – 2016.
Диссертация посвящена разработке аналоговых и цифровых инвариантных систем наведения и стабилизации основного вооружения танков на основе создания математических моделей возмущенного движения танковой пушки относительно оси цапф и танковой башни с пушкой относительно оси поворота, а также имитационных моделей внешних возмущений, действующих на основное вооружение в каналах вертикального и горизонтального наведения. Показано, что повышение степени инвариантности замкнутой системы стабилизации к действию внешних возмущений, за счет объединения в стабилизаторе двух основных принципов управления – принципа управления по отклонению и принципа управления по возмущению, приводит к снижению запаса устойчивости замкнутой системы. Для сохранения требуемого запаса устойчивости предложено введение в систему дополнительного контура обратной связи по угловому ускорению объекта стабилизации. С использованием метода гармонической линеаризации нелинейностей решена задача отыскания амплитуд и частот автоколебаний рамок гироскопической платформы, используемой в качестве гироскопического датчика углов отклонения оси канала ствола танковой пушки от линии прицеливания, а также автоколебаний давления рабочей жидкости в гидросистеме стабилизатора канала вертикального наведения. Показано, что причиной возмущения автоколебаний в первом случае является нелинейная характеристика системы разгрузки гироплатформы и "сухое" трение в осях кардановых подвесов, а во втором случае – нелинейные характеристики предохранителей гидроклапанов. Сделан вывод о том, что такие автоколебания являются высокочастотной помехой, приводящей к снижению помехозащищенности замкнутой системы наведения и стабилизации. Рассмотрены особенности цифровой инвариантной системы стабилизации наведения и стабилизации танковой пушки, в частности, необходимость использование цифровых низкочастотных фильтров Баттеруорта и Ланцоша для фильтрации высокочастотных помех выходных сигналов датчиков. Доказано, что при построении цифрового стабилизатора танковой пушки целесообразно последовательно-параллельное использование цифровых фильтров Баттеруорта и Ланцоша. Разработана структура и осуществлен выбор варьируемых констант алгоритмов стабилизации, обеспечивающих инвариантность замкнутой системы наведения и стабилизации без существенного снижения её запаса устойчивости. Моделирование процессов наведения и стабилизации в замкнутой системе с последующим анализом этих процессов позволяет сделать вывод о значительном повышении точности отработки внешнего возмущения (в 1.8 – 1.9 раз) по сравнению со штатной.The thesis for the degree of candidate of technical sciences, specialty 05.13.03 – Systems and management processes. – National Technical University "Kharkov Polytechnic Institute", Kharkov – 2016.

It is shown that increasing the degree of invariance closed stabilization system to external perturbations lead to lower stability margin closed system. To maintain the desired stability margin suggested the introduction of the system of additional feedback path for the angular acceleration of the object of stabilization.

Дисертація присвячена розробці аналогових і цифрових інваріантних систем наведення і стабілізації основного озброєння танків на основі створення математичних моделей збуреного руху танкової гармати відносно вісі цапф і танкової башти з гарматою відносно вісі повороту, а також імітаційних моделей зовнішніх збурень, що діють на основне озброєння в каналах вертикального і горизонтального наведення. Показано, що підвищення ступеня інваріантності замкненої системи стабілізації до дії зовнішніх збурень приводить до зниження запасу стійкості замкненої системи. Для збереження потрібного запасу стійкості запропоновано введення до системи додаткового контуру зворотнього зв'язку за кутовим прискоренням об'єкту стабілізації.

Full textAbstract:
Syftet var att undersöka svenska kastartjejers, alltså kvinnor som sysslar med friidrottens kastgrenars, syn på kroppen och hur de ser på paradoxen med samhällets ideal kontra idrottens. Även frågor rörande genus, tränare och omgivningens syn togs upp. Studien genomfördes i två fokusgrupper med vardera fyra deltagare. Resultatet visade, i enlighet med tidigare forskning, att kropp och ideal upplevdes olika beroende på miljö. De idrottsliga idealen samstämde inte med samhällets. Tjejerna var nöjda med sina kroppar, men kunde utanför idrotten ibland känna sig annorlunda och önska sig en annan kropp. Under resans gång hade deltagarna ändå kommit att accepterat sina kroppar och det den kunde göra i form av idrottslig prestation. Tränarna talade alltid om kroppen ur synen att den skulle prestera, vilket också var fokus för deltagarna. Feminina ideal fick stå åt sidan, samtidigt som de ändå ville ses som tjejer. Utanför idrotten sågs de som starka, inom friidrotten möttes de ibland av fördomar och utanförskap. Särskilt kläderna bidrog till detta och förstärkte känslan av att vara onormal och okvinnlig även i idrottsmiljön. Med hjälp av Self Discrepancy Theory och The Social Comparsion Theory analyserades sedan resultaten. Förslag till vidare studier är bland annat hur kroppsbilden påverkas av skada eller avslutad karriär.

Full textAbstract:
Recent approaches solve the problem of robot motion and task planningby using formal methods-based model checking algorithms. Inthis work, we consider the software package P-MAS-TG, an automatictool to generate correct-by-design controllers for robot motion and taskplanning. The robot motion can be modelled as a finite-state transitionsystem and the task can be represented by a linear temporal logic formula.Then, using a model checking algorithm, an accepting path forthe robot motion can be found so that the robot satisfies the specificlinear temporal logic task. In this thesis, the process of searching forthe accepting path of the robot motion by P-MAS-TG is visualized bymeans of a graphical user interface (GUI) in form of an rqt plug-inwhere all requested inputs for the P-MAS-TG package can be definedin the GUI so that the process is simplified and user-friendly. Moreover,the GUI provides a simple hybrid control mechanism betweenthe initial linear temporal logic task and a temporary task that is insertedby a human.All functions of the GUI are implemented and demonstrated onthe TurtleBot platform. The experiment shows that the GUI and theP-MAS-TG are successfully integrated. Features of the P-MAS-TG areperformed with the GUI to conduct motion planning and task planningon the TurtleBot.Nya metoder lösa problemet med robot motion och task planningmed hjälp av formella metoder-baserade modellkontroll algoritmer. Idetta exjobb anser vi att programvarupaketet P-MAS-TG, ett automatisktverktyg för att generera correct-by-design controllers för robotmotion och task planning. Robot motion kan modelleras som ett ändligttillstånd övergångssystem och uppgiften kan representeras av enlinjär temporal logik formel. Sedan, med hjälp av en modellkontrollalgoritm, kan en accepterande väg för roboten rörelse hittas så att robotenuppfyller de specifika linjära temporala logik uppgift. I dennauppsats processen att söka efter den accepterande sökvägen till robotmotion av P-MAS-TG visualiseras med hjälp av ett grafiskt användargränssnitt(GUI) i form av en rqt plug-in där alla efterfrågade indataför P-MAS-TG-paketet kan definieras i GUI så att process är förenklatoch användarvänligt. Dessutom ger GUI en enkel hybrid kontrollmekanismmellan den ursprungliga linjära temporala logisk uppgift ochen tillfällig uppgift som infogas av en människa.Alla funktioner i GUI implementeras och demonstreras på TurtleBotplattformen.Experimentet visar att GUI och P-MAS-TG är framgångsriktintegrerade. Egenskaper hos P-MAS-TG utförs med GUI för attgenomföra motion planning och task planning på TurtleBot.

The purpose of this thesis is to study the way the European Union and Sweden respectively frame the subject of cybersecurity, to see whether their framing differs and what consequences that may have. In order to study this, the thesis will study the cybersecurity strategies of the European Union and Sweden through a discourse analysis according to the Copenhagen school’s theory of securitization. The purpose is to see what the two actors define as the object that needs to be secured, what threatens said object and what measures should be taken to secure it. To study the cybersecurity strategies, data will be gathered from the European Union’s Cybersecurity Act of 2019 and Sweden’s six cybersecurity priorities, alongside other policy papers deemed relevant. The two points will then be compared in order to see how the framing align or contrast, to see what consequences that may bring.

Full textAbstract:
In the discipline of Historical Geography, capital location and planning of administrative districts are crucial issues. Since they have often been considered as two separate topics, attention, if any, has scarcely been paid to the relationship between them. The capital of China was transferred eastwards from Chang’an in the Tang dynasty to Kaifeng in the Song dynasty and then to Dadou in the Yuan dynasty, a critical transitional period in Chinese history which spanned three dynasties and seven hundred plus years. The way how administrative districts were planned changed with these transfers. This research investigates the relationship between the location of capitals and the planning of administrative districts with reference to these three dynasties.
This thesis is comprised of eight chapters. The first one is an introduction, which briefly discusses how Confucianism sees the relationship between the location of capitals and the planning of administrative districts. This chapter also includes a literature review, research methodologies and the significance of this research.
What follows is an elucidation of the Centre Theory (Juzhonglun居中論), which is concerned with the location of the capital. The chapter will probe into how the theory came into being, its significance, where the centre of ‘the world’ (tianxia天下) was, and look into how this theory was influential as a factor in determining the location of the capital before the Tang dynasty.
The third chapter explains the locations of the capitals in the three dynasties with reference to the Centre Theory. It was found that the location of the capitals in the three dynasties accorded with the principles of the Centre Theory, despite the fact that the territory, the river system that transported grain to the capital, and the idea of ‘the world’ in the eyes of the ruler were all different in the three dynasties.
The fourth chapter explores the relationship between the capital and the jingji (the capital city and its environs京畿), including the area of the jingjiin the Tang, Song, and Yuan dynasties, the evolution of the jingji system, and the significance of setting up the jingji.
Chapter five is a study on the relationship between the location of the capital city and the sub-capital. The sub-capital, which was complementary in nature, was usually not far away from the capital city and would move with the transfer of the capital.
Whilst the sixth chapter examines the relationship between the location of the capital and the establishment of higher administrative districts, chapter seven analyses the relationship between the location of the capital and the distribution of prefectures and counties. With the relocation of the capital from Chang’an to Dadou, these seven hundred plus years witnessed a gradual clustering of prefectures and counties in the east.
The last chapter is a generalisation of how the planning of administrative districts transformed with the transfer of capital cities from the Tang to Yuan dynasties.published_or_final_version

Previous issue date: 2007-12-05On this paper, it is made a comparative analysis among a controller fuzzy coupled to a PID neural adjusted by an AGwith several traditional control techniques, all of them applied in a system of tanks (I model of 2nd order non lineal). With the objective of making possible the techniques involved in the comparative analysis and to validate the control to be compared, simulations were accomplished of some control techniques (conventional PID adjusted by GA, Neural PID (PIDN) adjusted by GA, Fuzzy PI, two Fuzzy attached to a PID Neural adjusted by GA and Fuzzy MISO (3 inputs) attached to a PIDN adjusted by GA) to have some comparative effects with the considered controller. After doing, all the tests, some control structures were elected from all the tested techniques on the simulating stage (conventional PID adjusted by GA, Fuzzy PI, two Fuzzy attached to a PIDN adjusted by GA and Fuzzy MISO (3 inputs) attached to a PIDN adjusted by GA), to be implemented at the real system of tanks. These two kinds of operation, both the simulated and the real, were very important to achieve a solid basement in order to establish the comparisons and the possible validations show by the results

Full textAbstract:
The intellectual development in the Tang Dynasty (618-907) could be generally divided into two phases, with the first one inherited from the Han Wei period focusing on the meaning of words, while the second phase focuses on the teaching of the Confucian classics. Among the various scholars during the course of this transformation, Dan Zhu (啖助,724-770) has been recognized as a non-mainstream but yet very influential character.
To avoid the An-Shi Rebellion, Dan Zhu resided in the south-eastern part of the country where he taught Lu Chun (陸淳) the Chun Qiu (春秋) classic. Many famous Tang political reformers including Lu Wen (呂溫) and Liu Zong Yuan (柳宗元) are considered by historians as Dan Zhu’s students and followers. This has made Dan Zhu even more influential than other Confucius scholars in that period. Nevertheless, due to the controversial nature of his teachings, Dan Zhu was heavily criticized by Ouyang Xiu (歐陽修) as being specious and at the same time appraised by Cheng Yi (程頤) to be one of the fore-runners who founded the Song Confucianism.
This research reveals that Dan Zhu abandons the approach of focusing on the meaning wording and goes directly into the teachings of the classics. He considers that there are large amount of mistakes in the then contemporary explanation of Chun Qiu, he also considers that Tang scholars have not just worked in isolation without much view sharing, but also misinterpreted Confucius’ teachings. Moreover, the Tang scholars are treating Chun Qiu as history or even as literature, rather than Confucius’ teaching on how the society should be run. From Dan Zhu’s perspective, Confucius was trying to make use of histories to set proper behavioural standards and protocols for running the country, with an objective of saving the imperial control of Zhou (周).
During the mid-Tang period, China was undergoing major social changes from a feudal to a modern society. Tang imperials whose ancestors carried a nomadic blood stream tried to strengthen their control by adopting Confucianism; and placing more emphasis on the south-eastern region where the Han Chinese of the Southern Dynasty was concentrated. Coupling with the civil examination (科舉) reform and the impacts of Zen Buddhism, the Tang society was undergoing major social-political transformation which Dan Zhu was situated right on its course.
The research concludes that Dan Zhu’s ideas fit well with Xuan-zong’s (唐玄宗) appeal for revival of Confucius teachings and the social-political setting in Mid-Tang. Although Dan Zhu is considered a non-mainstream scholar, his teachings have brought about significant impacts on later development of the Neo-Confucianism. Nonetheless, Dan Zhu has not deviated from the fundamental principles of a Confucian whose destiny is to serve the people and the country, and of course for Dan Zhu, the Tang Dynasty.published_or_final_version

Falls and their consequences among older people are a serious medical and public health problem. Identifying individuals at risk of falling is therefore a major concern. The purpose of this thesis was to evaluate measurement tools of balance control and their predictive value when screening for fall risk in physically dependent individuals ≥65 years old living in residential care facilities, and physically independent individuals ≥75 years old living in the community. Following baseline assessments falls were monitored during six months in physically dependent individuals based on staff reports, and during one year in physically independent individuals based on self reports. In physically dependent individuals test-retest reliability of the Timed Up&Go test (TUG) was established in relation to cognitive impairment. Absolute reliability measures exposed substantial day-to-day variability in mobility performance at an individual level despite excellent relative reliability (ICC 1.1 >0.90) regardless of cognitive function (MMSE ≥10). Fifty-three percent of the participants fell at least once during follow-up. Staff judgement of their residents’ fall risk had the best prognostic value for ruling in a fall risk in individuals judged with ‘high risk’ (positive Likelihood ratio, LR+ 2.8). Timed, and subjective rating of fall risk (modified Get Up&Go test, GUG-m) were useful for ruling out a high fall risk in individuals with TUG scores <15 seconds (negative LR, LR- 0.1) and GUG-m scores of ‘no fall risk’ (LR- 0.4), however few participants achieved such scores. In physically independent individuals balance control was challenged by dual-task performances. Subsequent dual-task costs in gait (DTC), i.e. the difference between single walking and walking with a simultaneous second task, were registered using an electronic mat. Forty-eight percent of the participants fell at least once during follow-up. A small prognostic guidance for ruling in a high fall risk was found for DTC in mean step width of ≤3.7 mm with a manual task (LR+ 2.3), and a small guidance for ruling out a high fall risk with DTC in mean step width of ≤3.6 mm with a cognitive task (LR- 0.5). In cross-sectional evaluations DTC related to an increased fall risk were associated with: sub-maximal physical performance stance scores (Odds Ratio, OR, 3.2 to 3.8), lower self-reported balance confidence (OR 2.6), higher activity avoidance (OR 2.1), mobility disability (OR 4.0), and cautious walking out-door (OR 3.0). However, these other measures of physical function failed to provide any guidance to fall risk in this population of seemingly able older persons. In conclusion – Fall risk assessments may guide clinicians in two directions, either in ruling in or in ruling out a high fall risk. A single cut-off score, however, does not necessarily give guidance in both directions. Staff experienced knowledge is superior to a single assessment of mobility performance for ruling in a high fall risk. Clinicians need to consider the day-to-day variability in mobility when interpreting the TUG score of a physically dependent individual. DTC of gait can, depending on the type of secondary task, indicate a functional limitation related to an increased fall risk or a flexible capacity related to a decreased fall risk. DTC in mean step width seems to be a valid measure of balance control in physically independent older people and may be a valuable part of the physical examination of balance and gait when screening for fall risk as other measures of balance control may fail to provide any guidance of fall risk in this population.

Full textAbstract:
The aim of this master thesis is to introduce a new technique for the design of cellular automata which will provide a better possibilities for the implementation and solving given problems in an environment of non-uniform automata. In this work, the theoretical foundations of cellular automata have been summarized and the possibilities of their design were examined using two evolutionary principles that have commonly been used - genetic algorithm and cellular programming. Two principally different issues were selected on which the possibilities and capabilities of these techniques were proven: the synchronization problem and the system of implementation of logic gates in an environment of cellular automata. Based on a review of the implementation properties and the initial results of usage of these methods a new design method for cellular automata was created - cellular evolution. The cellular evolution with its method of "prediction of the future state of surrounding cells" provides new possibilities in the design of cellular automata since it operates with structured genes which allow the gene to be active for a variety of cellular surroundings. In the conclusion of this work, all three methods were compared on two selected problems and their abilities were summarized in a detailed overview.

This thesis studies the gun stabilizing control of a battle tank. This study formulates the problem and proposes a control strategy to stabilize the gun. The result provides the National Army an initial guideline for the stabilization system design of the development of the third generation battle tank.The system is modeled as the gun and turret on a moving base. The kinematics and the dynamic equations are derived. The system is stabilized by applying a feedback linearization technique in the inner loop and two PD controllers in the outer loop. The parameters of the PD controller are found by an experimental design method in which the variation of the mass of the turret are consider. Thus, the robustness with respect to the variation of the mass is guaranteed.The simulation results show that comparing with the case without control, the control strategy can reduce the disturbance more than 25 dB.

The study aims to evaluate the pharmacokinetic differences of bioactive constituents between commercial extract and traditional decoction of Ge-Gen Tang, Shu-Ching-Huo-Hsieh Tang and Shao-Yao-Gan-Cao Tang. The rapid and sensitive quantitative methods for glycyrrhizin and paeoniflorin in plasma samples are developed and validated by using HPLC. After oral administration of Ge-Gen Tang, Shu-Ching-Huo-Hsieh Tang and Shao-Yao-Gan-Cao Tang, the plasma levels-time profiles of glycyrrhizin were adequately described by an one-compartment model. The results showed that after oral administration of commercial extract in New Zealand rabbit, the AUC 0-∞, C max is significantly larger than traditional decoction in GT (AUC 0-∞: 49.28 ± 16.9 and 17.89 ± 2.01; C max : 3.61 ± 0.25 μg/ml and 1.24 ± 0.16 μg/ml), the T max in decoction was shorter than commercial extract of SYGCT (T max 6.89 hr and 10.94 hr), and after oral administration SCHACHT showing same result. The T max of traditional decoction was 7.08 hr and of commercial extract was 8.30 hr. So the pharmacokinetic results are useful for quality control and clinical pharmacokinetic studies of commercial extracts and traditional decoctions of GT, SCHHT and SYGCT.

Sheng-Ma-Ge-Gen-Tang was used to examined for the antiviral activity against measles virus in human peripherial blood mononuclear cells (PBMC) and Vero cells. 100 μg/ml of Sheng-Ma-Ge-Gen-Tang in PBMC showed significant anti-measles activity, whereas that of in Vero cells were not. After eight days of infection, the release of virus were completely suppresis by Sheng-Ma-Ge-Gen-Tang in PBMC. Furthermore, Sheng- Ma-Ge-Gen-Tang has a significant selective stimulating effect on the secretion of cytokine TNF-a in PBMC. Time kinetic analysis indicated that the stimulation of secretion was rapid and detected as soon 2 hrs following stimulation of the PBMC and raised to optimal amount at 8-12 hrs. These suggest that the magnification of anti-measles activity of this agent is lymphocyte dependent and may mediate by TNF-a.

Summary Quality Evaluation Three Chinese Herbal Extracted Preparations Produced in Taiwan of Ma-Xing-Gan-Shi Tang ,Si Ni San, and Wn Tan Tong by Hsiu Mi Yang Graduate Institute of Chinese Pharmaceutical Sciences China Medical College There are more than 20 Pharmaceutical factories manufacturing extracted Powder preparations of Chinese crude drugs in Taiwan. The market price of these preparations varied from company to company. We compared the quality of these preparations and also evaluated the quality between the Chinese herbal formulas preparations and the tranditional Chinese crude drugs. This project selected five most commonly used Chinese herbal formulas preparations ( Ma Xing Gan Shi Tang, Si Ni San, Wn Tan Tong ) used in the China Medical College Hospital. We evaluated the quality between the Chinese herbal formulas preparations and the traditional Chinese crude drug based on the following parameters : ( 1 ) Loss on drying ( 2 ) Total ash content ( 3 ) Acid insoluable ash content ( 4 ) Dilute alcohol extract content We also used TLC, HPLC to compare the quality of preparations between the pharmaceutical factories. The analysis showed the quality of products from different factories varied dramatically. The National Health Bureau should enforce the quantitive analysis of the herbal products so as to guarantee their quality. Finally, we wish the Bureau of National Health Insurance can offer different rates to the healthy organizations, based on the quality of herbal preparations so as to improve the quality of the treatment and accelerate the quality control of G.M.P. products.

Depression is a kind of psychiatric disorders that affects more than 10% of the general population. The clinical treatments used nowadays always cause several side-effects such as losing body weight and reducing appetite. Therefore, we expect to look for the alternative treatment simultaneous with antidepressant effect and less side-effect. Gan-Mai-Dazao-Tang is a traditional decoction used to treat depression and anxiety. The ingredients of Gan-Mai-Dazao-Tang include Glycyrrhiza uralensis Fisch. (licorice), Triticum aestivum L. (wheat) and Zizyphus jujuba Mill. (jujube). It can nourish the heart, tranquilize the mind, invigorate the spleen and replenish qi (氣) in the traditional Chinese medicine. The objective of this study is to investigate the antidepressant effects of Gan-Mai-Dazao-Tang and its ingredients in rats on the forced-swim test (FST) – an animal model for predicting the clinical efficacy of antidepressants. Eight-week-old male Nerl: Wistar rats were randomized to C (10 mL/kg bw dd H2O), L (0.4 g/kg bw licorice extract), W (1.6 g/kg bw wheat extract), J (0.5 g/kg bw jujube extract), LWJ [2.5 g/kg bw of complex extract (licorice: wheat: jujube = 5:20:6)] and P (18 mg/kg bw Prozac) groups. Samples were administered by gavage for 21 days. After FST, the animals were sacrificed and their brains were collected for monoamines analysis. The results have shown that the body weight and the appetite of rats were significantly lowered in P group (p<0.05), while the other groups were not significantly different with each other. The immobility time in FST was significantly decreased in LWJ and P group compared with control (p<0.05), but the ingredients of Gan-Mai-Dazao-Tang showed no significantly antidepressant effect in FST. The concentration of serotonin (5-HT) in frontal cortex were significantly higher in LWJ and P group compared with control (p<0.05), although 5-hydroxyindoleacetic acid in frontal cortex and amygdale were not significantly different between LWJ and the control group. However, administration of LWJ and P significantly increased the dopamine (DA) concentration (p<0.05) and decreased the concentration of 3,4-dihydroxyphenylacetic acid (DOPAC) (p<0.05) and DOPAC/DA turnover (p<0.05) in striatum compared to the control. The results indicate that Gan-Mai-Dazao-Tang may have the potential antidepressant effect and less side-effect in rats.

Portal hypertension is a major complication of liver cirrhosis. Cirrhosis and portal hypertension are associated with abnormalities in the cardiovascular system, with the development of a hyperkinetic circulatory state characterized by an increase in cardiac output, portal pressure, splanchnic blood flow and a decrease in arterial blood pressure and peripheral vascular resistance. Pharmacological therapy of portal hypertension aims to reduce portal blood inflow and/or intra-hepatic resistance. Long-Dan-Xie-Gan-Tang (LDXGT) is a commonly used traditional Chinese medicine in patients with chronic liver diseases in Taiwan. The hemodynamic effects of LDXGT in cirrhotic rats have not been explored. Although there are clinical reports showing portal hypotensive effects of carvedilol, a non-selectiveβ-adenoceptor antagonist withα1- adenoceptor antagonistic activity, the detailed hemodynamic effects in cirrhotic rats are also lacking. Propranolol, a β-adenoceptor antagonist, has been reported to reduce portal pressure in patients with cirrhosis, but the detailed hemodynamic effects in cirrhotic rats remain unclear. The present study was aimed to investigate the hemodynamic effects of LDXGT, carvedilol and propranolol administration in cirrhotic rats. Portal hypertension with cirrhosis was induced by chronic bile duct ligation (CBDL) in Sprague-Dawley rats (230 ~ 250 g). Cirrhotic rats were allocated into separate groups: CBDL-Treatment group and CBDL-Vehicle group. Sham-operated rats served as controls. LDXGT and carvedilol was administered for 1-Week or 4-Week by gavage, starting at 3 weeks after ligation or at the time of ligation, respectively. Hemodynamic studies were performed by radioactive microsphere method after an overnight fast. We also investigate whether acute LDXGT i.v. infusion exerted a direct vasopressor effect by thermodilution method. Our results showed that: (1) 1-Week carvedilol (5 mg/kg, bid, p.o.) administration partially ameliorated the hyperdynamic state of CBDL rats, including a significant decrease in heart rate, cardiac index, portal pressure, portal tributary blood flow and renal blood flow and an increase in systemic vascular resistance and renal vascular resistance. (2) 1-Week propranolol (15mg/kg, bid, p.o.) administration also partially ameliorated the hyperdynamic state of CBDL rats. (3) 1-Week LDXGTH (333 mg/kg, bid, p.o.) administration only caused a significant decrease in cardiac index and an increase in systemic vascular resistance. However, splanchnic hyperdynamic state did not changed after 1-Week LDXGTH administration. (4) 4-Week LDXGTH administration not only significantly ameliorated systemic hyperdynamic state but also caused a beneficial effect in splanchnic hyperdynamics, including a decrease in portal venous pressure and an increase in portal territory as well as renal vascular resistance. (5) 4-Week LDXGTL (111 mg/kg, bid, p.o.) administration exerted beneficial effects in both systemic and splanchnic hyperdynamic state. However, there was not a dose response relationship between 4-Week LDXGTL and LDXGTH administration. (6) Acute LDXGT i.v. infusion seems not to exert a vasopressor effect. Our results suggested that 1-Week carvedilol, propranolol and 4-Week LDXGT treatment may provide beneficial effects in the management of portal hypertension and hyperdynamic circulation on cirrhotic rats.

In Ming Dynasty, in addition to Jian Deng and Yan Yi series, there were many other fictions about contemporary concern, social reflection, and ideology. Among them, Wang Ton-Ggui'' s Er Tan was one of the best, which was welcomed by the readers, became the material resources of short stories and dramas, and influenced the later records strange or supernatural events novel such as Liao Zhai Zhi Yi. However, the circulation of Er Tan became very rare since Qing Dynasty. Recently, there were researches on the evolution and preservation of folk stories in Er Tan, but the author’s life and the printing era of the fiction still remain questioned. This article aims to answer these questions about author and printing era, and to illustrate the importance of Er Tan in Chinese fiction evolution by discussing the citation of the fiction in other books, especially in Gu Jin Tan Gai.

Chronic liver injury results from repeatedly hepatic injury with persistent inflammation, hepatic stellate cell activation with scar formation and loss of normal architecture. Chronic inflammation is a common element in the pathogenesis of most chronic liver diseases which lead to liver fibrosis and cirrhosis. Ger-Gen-Chyn-Lian-Tang (GGCLT) is originally compiled by Zhang Zhong-Jing in Han dynasty. It has been shown to have biological effects including antioxicant and anti-inflammation. Its major constituents including puerarin, baicalin, berberine and glycyrrhizin also exhibit anti-inflammation and hepatoprotective effects. This study investigates the protective effects of GGCLT against chronic liver injury induced by thioacetamide (TAA) and the mechanism of its hepatoprotective effects. Male C57BL/6 mice were divided into six groups: normal control group, TAA 2wks group, TAA 4wks group and GGCLT group (33, 100, 330 mg/kg), respectively. All experimental groups except normal control group received TAA intraperitoneally (i.p.) injection twice weekly. After two weeks of TAA administration, GGCLT or vehicle was given by orally at GGCLT group or TAA group daily for two weeks. Mice were sacrificed after two or four weeks’ treatment, the liver and serum were collected for histopathology assay, immunohistochemistry, western blot and plasma alanine transaminase (ALT) assay. We demonstrated that GGCLT reduces TAA-induced elevated plasma ALT. Histological examination showed increased hepatocyte degeneration and necrosis in TAA group while GGCLT improved dose-dependently. GGCLT reduces TAA-induced liver inflammation, relative to down-regulation hepatic neutrophil, F4/80 expression, proinflammatory mediator NF-κB, pSTAT3 and PAI-1 protein levels. GGCLT also suppressed protein expressions of α-SMA and PDFGR. This study demonstrated that GGCLT could attenuate TAA-induced hepatic injury, inflammation and fibrosis. We suggest GGCLT could improve chronic liver injury and liver fibrosis.

Influenza viruses are major human pathogens that cause serious respiratory tract disease and seasonal transmission. Due to the highly morbidity and mortality of virus infection, effective treatment is required for against influenza viruses. There are currently two classes of anti-influenza drugs. One is M2 ion channel inhibitors (amantadine and rimantadine) and the other is NA inhibitors (oseltamivir and zanamivir). Due to the antigenic drift and shift of influenza viruses, emergence of these two drug-resistant viruses has become prevalent. For this reason, we tried to find out Chinese herb medicines that had been used for the treatment of common cold and cough. In this study, we prove that the prescription, MA-XING-GAN-SHI-TANG (MXGST) has anti-influenza virus activity based on the neutralization assay and cytopathic effect (CPE) analysis. According to time of addition assay, MXGST inhibited virus infection at early stage of viral relication. Pre-incubation of virus particles with MXGST was approved to delay the entry of virus and thus decreased the synthesis of viral proteins, such as NP and M1. Besides, we also proved that virus penetration was suppressed by MXGST rather than virus attachment based on penetration assay and attachment assay. Taken together, we demonstrated that MXGST has anti-influenza virus effect due to the blockade of virus entry.

In Tang Dynasty, there were more merchant fictions that appear the life style of merchant, due to the stable society and the blooming economy. The authors were specially focused on the characters of the roles to spread various plot and to develop writing skills. The artistry of Tang Dynasty merchant fictions influences the commercial philology in future age. It is worth to study the mentioned influence. This study divided into six chapters is based on the “Tai Pin Guan Chi” to analysis the artistry and value of Tang Dynasty merchant fictions. The development and maturity of Tang Dynasty merchant fictions reflect the distinguishing feature of the age, and expand the commercial philology in future age. It shows the importance and values of Tang Dynasty merchant fictions.
