This article presents the discussion on the etiological factors and pathogenesis of chloasma.On the basis of clinical experience and related literature from every dynasty,the author concludes that the causes and pathogenesis of chloasma can be summarized into 8 aspects: 1.Menoxenia,lesion of uterus and cunnus,tumors in pelvic cavity in women;excessive heat and deficiency of kidney essence in men.2.Damages in Chong-Ren meridians,e.g.infection of pathogen which goes directly into Chong-Ren;exhaustion of essence blood;coldness,phlegm or blood clot congests within the Chong-ren meridians.3.Stasis of liver-qi induced by insufficiency of blood storage and dysfunction in conveyance and dispersion.4.Shortage of essence blood.5.Lack of kidney-yang.6.Disharmony between spleen and stomach,including deficiency of spleen-stomach qi,spleen-stomach yang,and stomach yin,and surplus of stomach heat.7.Flooding of turbidness and heat,like moisture and heat in liver-gallbladder and in spleen-stomach.8.Invaded by exogenous pathogen of wind and sunlight.Knowing these points has great significance on directing therapy according to syndrome differentiation.

This article respectively introduces famous doctor ZHANG Xi-chun’s original experience of using mineral drugs from four parts: taking suitable measures in accordance with the disease mechanism,syndrome,herbs,clinical experience,which hope to inspire and guide our clinical doctors.

Objective: To evaluate effect of combination of PA and RES on human gastric carcinoma cell MGC803 in vitro.Methods :The effects of PA and RES were measured by MTT assay.Morphous of cell was observed by light microscope.Flow cytometry was used for MGC803 cell cycle analysis.Results: PA significantly inhibited the growth of MGC803 cell in a dose and time dependent way(P

"Absorbing image "is an important method in establishing fundamental theoretical system of TCM.The term and concept of "nomenclature according to manifestations" is the starting point of theoretical thoughts and the results of scientific studies."Testing viscera via the state of internal organs" is a method of "understanding the interior from the exterior",which makes TCM surpass productivity level and practical tools of that time,finally aquire knowledge.The huge theoretical system of TCM is constructed on the basis of "classification according to manifestation",discovering unknown fields according to infinite knowledge.

Objective: To observe effect of Kechuanning on expression of nuclear factor kB(NF-?B) in lung tissue of bronchial asthmatic rats.Methods: 40 rats were randomly divided into 5 groups: the normal group,the model group,Kechuanning high-dose group(27g/kg),Kechuanning low-dose group(13.5g/kg),GuilongKechuanning control group(0.45g/kg),8 rats in each group.The bronchial asthmatic model was established by egg protein sensibilization and long-term inhalation provocation.The rats of each treatment groups were lavage administration each day from the first time of provocation to execution.After 4 weeks of treatment,the rats were killed and lung tissue were taken to dyeing of HE to be observed.The expression of NF-?B in lung tissue were determined by immunohistochemistry.Result: Compared with the normal group,the thickness of bronchus wall and bronchus smooth muscle,the numbers of eosinophile granulocyte and leukomonocyte,and expression of NF-?B in lung tissue were increased in the model group(P

Objective: To study the influence of Ruhuang(Rhubarb and Lactohacillin) preparation to endotoxin and intestinal defence function of cirrhotic rats.Methods:88 male Wister rats were randomly divided into normal group,model group,prevention group,prevention of control group,model treatment group and model treatment of control group.Liver cirrhosis model was induced by CCl4 combined with other factors,Ruhuang preparation was used for the prevention and treatment,lactulose was used as positive control drug.The level of plasma endotoxin,intestinal mucosal S-IgA and serum D-lactic acid were detected.Results : The blood plasma endotoxin level of Ruhuang prevention group and model treatment group is lower than that of model group obviously(P

Objective: To investigate the inhibitory effect of Dahuangzhechong pill to platelet activation.Methods: The blood platelet were incubated with the medicated blood plasma with Dahuangzhechong pill,and then activated with ADP and marked with PAC-1 monoclonal antibody.The activation rate of blood platelet was analyzed by flow cytometer.The patients with coronary heart disease or cerebral infarction took Dahuangzhechong pill,after one course of treatment,the patients,blood platelet were separated and then incubated with PAC-1 monoclonal antibody.The activation of blood platelet was detected by ? ow cytometer.Results: Compared with aspirin group(51.7%),the activation rate(20.82%) of blood platelet in Dahuangzhechong pill group decreased(P

Theory of property of Chinese herbs is not only core contents in theorectical system of TCM,but also important basis on guiding clinical usage of TCM.Following modern science and technology combined with TCM,theory of property of Chinese herbs has been rising to new height.Theory of properties’ separation of Chinese herbs is put forward in accordance with substances’ separation and functions’ separation of Chinese herbs in order to widen intension of theory of property of Chinese herbs,explore its space and guide the practice of TCM.

The nomenclature of rheumatism is very miscellaneous and varied,seriously influencing academic intercourse and development.In order to standardize the nomenclature and classification,this article,on the basis of studying historical documents and learning from clinical achievements,closely combined clinical practice to research every disease’s name in history corresponding to every patient in clinic.After testing,verifying and comparing repeatedly,these names are now standardized into 4 classes over 60 names from 15 classes over 400 names in history.These new over 60 rheumatism names which are classified after taking view of cause,site,symptom,and characteristics of disease possess scientific and practical value.

Objective: To research the effect of Xinkai Kujiang method on gastric myoelectrical activity and autonomic nerve function in functional dyspepsia(functional Thirty,FD) rat,and to reveal the overall regulatory mechanism of Xinkai Kujiang method and help for the clinical trials and treatment.Methods: FD rats being the experiment subject,we observed the effects of Xinkai Kujiang method on FD rat gastrointestinal movement,including the following index,the main frequency,power,even the percentage of slow wave duality.Meanwhile we observed the effect of Xinkai Kujiang method on FD rat heart ratevariability(HRV),evaluated the effect on autonomic nerve function,and revealed FD rats overall adjustment mechanism.Results: Before treatment,the result of model group,weikangning group and the normal control group was significantly different(P0.05),but that of weikangning and the model group had significant differences(P0.05),weikangning group change trend was significantly different(P
