ABSTRACT
OBJECTIVE:To optimize the extraction technology of garlic oil. METHODS:Using extraction rate of garlic oil as index,based on single factor test,Box-Behnken response surface method was used to optimize conditions of steam distillation method for the extraction of garlic as fermentation time,solid to liquid ratio,fermentation temperature and the verification test were made for the optimized technology. RESULTS:The optimal extraction technology was as follows as fermentation time of 4.5 h,solid to liquid ratio of 1:7,fermentation temperature of 55 ℃. The average extraction rate of garlic oil in verification test was 0.32%(RSD=1.43%,n=3);the relative error between the measured value and predicted value was 0.06%. CONCLUSIONS:Box-Behnken response surface method is simple,reasonable and feasible to optimize the extraction technology of garlic oil,which can provide a scientific basis for industrial production.
ABSTRACT
Objective To optimize extraction technology of flavonesingredients from Herba Epimedii by uniform design. Methods Ultraviolet spectrophotometry was adopted to determine the content of total flavonoids. Content of epimedin A, epimedin B,epimedin C,icariin and baohuosideⅠ were determined by HPLC. U10?( 108 ) uniform design was used to conduct the multiple comprehensive evaluation of six ingredients and comprehensively analyze the influence of the concentration and amount of ethanol, extracting time on extraction of flavonesin gredients from Herba Epimedii. Results The uniform design experiment showed that 15-fold weight of 60% ethanol,extracting 2 times and each time with 165 min were the optimum extraction condition. Conclusion The method is easy and reasonable to handle,has stable and reliable results,and good repeatability and feasibility.It can be applied in industrial production.
ABSTRACT
Acquired immune deficiency syndrome (AIDS) is a worldwide public health problem and an incurable disease. The roles of Traditional Chinese Medicine (TCM) on AIDS had been recognized and accepted by more and more people. Being a relatively long period, to initiate combination antiretroviral therapy (cART) for the asymptomatic human immunodeficiency virus (HIV) infection patient is not consensus. According to TCM theory, not only the imbalance of Yin and Yang but also the disharmony of internal body function and external natural environment had occurred in the body of the patient, the imbalance and the disharmony should be adjusted by the means of the treatment based on the patters identified among the symptoms in terms of TCM. We aimed to analyze the feature of patients with asymptomatic infection, and compare the advantages and disadvantages of the us- age of cART for asymptomatic infection, explored the possible mechanism underlying TCM treatment of the asymptomatic infection, by reviewing the TCM treatment progress on asymptomatic HIV infection.

From the Chinese medicine point of view on the physiological functions of healthy atmosphere and vitality, healthy atmosphere and vitality of the relationship, we can know that healthy atmosphere and vitality has important role in the life activities of the body. They complement each other. In the pathogenesis of AIDS, AIDS epidemic poi-son has the characteristics of wounding healthy atmosphere. When it attacks the body upright, vitality will be injured firstly. Because of that it is inextricably linked with the characteristics of the AIDS epidemic poison and vitality physiological functions. Therefore, AIDS epidemic poison attacks healthy atmosphere and vitality co-exist, the injury of healthy atmosphere and vitality is throughout the whole process of AIDS .
ABSTRACT
This study was aimed to observe influence on clinical symptoms of Qing-Fei Pei-Yuan Wei-Wan (QFPY-WW) for pulmonary infection HIV/AIDS cases with the syndrome of phlegm-heat obstructing the lung. A total of 141 pulmonary infection HIV/AIDS cases with the syndrome of phlegm-heat obstructing the lung were randomly divided into the treatment group (94 cases) and the control group (47 cases). The treatment group was given basic western medication combined with QFPYWW. The control group was given basic western medication. After 4 weeks treat-ment, observation was made on changes of main symptoms. The results showed that on the 28th day, compared with the control group, there was improvement on symptoms such as cough, breathing and chest tightness (P< 0.05). Com-parison on coughing up phlegm degree showed that the treatment group was significantly better than the control group (P< 0.05). On the 7th day treatment, the treatment group had better effect on lowering body temperature than the control group (P< 0.05). It was concluded that QFPYWW can improve symptoms such as cough, breathing, chest tightness and cough up phlegm among pulmonary infection HIV/AIDS patients.
ABSTRACT
The eastern and western medicine have different thinking mode under different philosophy. This article discussed on special ethical issues which were encountered in the clinical research of traditional Chinese medicine (TCM) and different from western medicine. The connotation of ethical review should also be adapted to the characteristics of TCM. This paper discussed these problems, and put forward the idea that ethical review system should be built according to TCM characteristics. Standards for TCM ethical review should be established in order to promote the research progress of TCM and maintain the legitimate rights of TCM subjects.
