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 introduces the academic thoughts and clinical experience of LIANG Shi-shao,a late famous TCM practitioner in Guangxi.Professor LIANG had practiced medicine more than 60 years,having rigid attitude toward teaching and great scholastic achievement,being good at treating diseases caused by exogenous pathogenic factor and internal damage,specializing in senile diseases.He thought highly of vital qi in clinical treatment,applying invigoration method in flexible way to preserve gastric qi.Because dwelled in south of china,professor LIANG was also skilled in treating warm disease,having original experience and comprehension of applying "clearing,hua,purgative" to remove dampness.In clinical practice,he was also good at improving drugs and prescription in order to curing difficult and complicated diseases,formatting a unique style of principle of diagnosis and treatment and experience.

Some medical charicteritics in the early ancient times are discussed centering on Yijingbianqi Lun in Suwen in order to expound the far-reaching impact of introspection-characterized Chinese culture on early traditional Chinese medicine.At the same time,the article also discussed Stability and Wisdom in the embodiment of Inner Canon of Huangdi.

The corresponding season of the ve zang-viscera is the important content of the correspondence between man and universe theory in the Inner Canon of Huangdi,and the corresponding season of the ve zang-viscera related to several modes of calendar.With the exception of the way that combine the ve zang-viscera with calendar which make use of criss and cross or divide into ve parts on 12 months of a year,the authors believe that the newly discovered ancient ten months' calendar had been showed clearly in the Inner Canon of Huangdi.The text of the Inner Canon of Huangdi that cannot be explained well in accordance with twelve months' calendar can be explained by ancient ten months' calendar,and the ancient ten months' calendar is the basis that the ve phases theory is derived from the concept of the ve seasons.

According to the causes and pathogenesis of lung cancer in traditional medicine,the principle of syndrome differentiation and treatment,the research achievements of modern medicine,we discuss the idea and method of syndrome differentiation and treatment of lung cancer by integrated traditional and western medicine.We believe the treatment of lung cancer can be taken from several aspects:strengthening body essence and eliminating pathogen;individualized treatment according to the principle of syndrome differentiation and treatment;combining differential symptoms and diagnosis of diseases according to achievements of lung cancer treatment in traditional medicine;choosing suitable treatment by integrated traditional and western medicine considering the different stage of lung cancer.

Objective:To study potential function of relieving-pain,calming and stopping bleeding function of astragali.Methods:To observe the effect of the water decoction of high,middle and low doses astragali on physical pain(hot plate method) and chemical-induced pain(writhing method)in mice reaction;the effect on the sleep durance of mouse which was applied under valve dosage of sodium pentobarbital and impact of blood coagulation in rats.It was compared with the blank control group,as well as the positive control group.Results:Astragali decoction can increase the pain threshold in mice,reduce the number of writhing in mice,enhance the volume of the role of sleep in mice on the threshold of sodium pentobarbital hypnosis,and extend the role of sodium pentobarbital hypnosis time.At the same time can shorten the prothrombin time and partial thromboplastin time,and increase fibrinogen.Conclusion:Astragali had definite relieving-pain,calming and stopping bleeding function.This result was consistent with the analysis conclusions through ancient prescriptions database with astragali.

Objective:The fingerprint chromatograms were established for quality evaluation of Sedum aizoon L.collected from different habitats by HPLC.Methods:The analysis was performed on a Diamonsil C18 column(4.6mm? 250mm,5?m)with acetonitrile-water(acidified to 0.5%with phosphoric acid)as mobile phase in a gradient mode at a flow rate of 1.0 mL/min,and at a column temperature of 25℃.The detection of wavelength was at 254 nm.Results:2lpeaks were selected as the common fingerprint peaks.The relative standard deviations for relative retention values and relative peak areas were less than 3%in the precision and repeated test.The similarity of l0 batches of samples were no less than 0.9.Conclusion:The method was reliable and can be helpful on the quality control of Sedum aizoon L.

Objective:To investigate the mechanism of Buguozhi Decoction in improving learning-memory of vascular dementia model rats.Methods:The rat models with VaD were established by bilateral occlusion of both common carotid arteries(2 一V0).The gene expressions of ER-?,NR2B were evaluated by RT-PCR and immunohistochemistry.Results:Buguozhi Decoction can significantly improve mRNA and protien pruducts of ER-?,NR2B gene in hippocampus of the vascular dementia model rats,compared with the model group(P

0.900.Comparison of the HPLC profiles of the total flavonoids material and the effective parts of the total flavonoids was established and the similarity with the corresponding Citrus Aurantium L.var daidai Tanaka fruits indicated that they were closely related to each other.Conclusion:The HPLC fingerprints of the medicine material and the effective parts of the total flavonoids with high specificity and can be used to control its quality.

Objective:To explore the effects of Shenqi Compound Recipe on the expression of Cycloxygenase-2 (COX-2)mRNA in aorta in GK rats.There were five groups:GK group,model group,atorvastatin group,Shenqi Compound Recipe group and normal control group.During the experiment periods,each group was administrated correspondent substance respectively for 35 days.Serum concentrations of C reactive protein(CRP)were determined by ELISA.The mRNA expressions of COX-2 in aorta were detemined by reverse transcriptase PCR(RT-PCR).Results:Compared with model group,concentrations of CRP in serum and the mRNA expression of COX-2 all decreased in atorvastatin group and Shenqi Compound Recipe group(P
