The emphasis should be made on the optimization of Chinese medicine clinical trial from the topic selection , operation mode and quality control . A comprehensive and detailed management system should be worked out to ensure the smooth conduction of clinical trials. The clinical research results should be clarified to achieve high quantity and quality outputs . The article was aimed to provide references for the development and breakthrough of Chinese medicine clinical trials .

This study was aimed to mine correlation between the cause and traditional Chinese medicine ( TCM ) syndrome of polycystic ovary syndrome ( PCOS ) from different angles and at different levels . The study found
that the inherent laws of the cause and syndrome by the application of different statistical methods and data mining methods . The literature information database of PCOS was searched . And the Microsoft Office Excel and the Microsoft Office Access were used in the establishment o the database . And the SPSS17 . 0 was used as the statistical software . The Medisc-3S system was used as the mining tools to discover the rules between etiology and syndrome . The function of frequency statistics and complex networks were used to discover and summarize the TCM syndrome and treatment of PCOS . The TCM syndrome and treatment of PCOS were discov-ered and summarized according to the statistical results . And the results showed that three reasons of etiology and pathogenesis of PCOS contained kidney-deficiency , phlegm-dampness , and blood-stasis . The five types of TCM syndrome included spleen-kidney deficiency , kidney-deficiency and blood-stasis , spleen-deficiency and phlegm-dampness , kidney-deficiency and phlegm-dampness , kidney-deficiency and liver stagnation . It was concluded that the treatment should be mainly from kidney-tonification and assisted with blood-activation and phlegm-removing . The association rules and complex networks of data mining methods were applied in the lit-erature research of PCOS . The results provided literature references and statistical evidences for the phlegm-dampness accumulation in the uterus as the pathogenesis of PCOS , and the methods of kidney-tonification , blood-activation and phlegm-removing as the treatment principles .

Objective To investigate the effects of pseudolaric acid B(PAB) on the invasiveness and metastatic activity of cervical cancer HeLa cells in vitro and the possible mechanism.Methods HeLa cells were divided into 5 groups: blank control group,DDP 3.125?g/ml group,20?mol/L PAB group,10?mol/L PAB group and 5?mol/L PAB group.The effect of PAB on invasive ability of HeLa cells was observed with a Transwell cell culture chamber.The mRNA expression of MMP22 and MMP29 in HeLa cells was detected by RT-PCR and the protein expression was detected by Western blotting.Results The average number of invaded HeLa cells was 15.60?2.45 in 20?mol/L PAB group and 20.14?2.48 in 10?mol/L PAB group,which was significantly lower than those in control group(46.50?4.70) and PAB 5?mol/L group(42.44?5.80,P

Phlegm is an important etiopathogenisis of female reproductive dysfunction in TCM.ZHU Dan-xi put forward the famous constitution theory of "phlegm in fat people",and there was internal regularity in pathogenesis of wemen with phlegm-dampness constitution.His viewpoint guided the clinical treatment objectively and provided a solid theorectical basis of preventing and treating female reproductive dysfunction induced by phlegm-dapness.Therefore,this paper will discuss the relationship between phlegm-dampness constitution and female reproductive dysfunction from the characteristics of pglegm-dampness constitute,correlation of obesity and pglegm-dampness constitute,and so on.

Polycystic ovary syndrome(PCOS),one of the most common causes of anovulation-induced infertility,is largely dependent on the influence of obesity and metabolic alterations,including an insulinresistant state and the metabolic syndrome,which consistently affect most women with PCOS.The clinical phenotype and the pathophysiological interact between obesity and PCOS have also been changed obviously in these paitients.Obesity has profound effects on the reproductive function of PCOS women and,particularly the abdominal phenotype,may add to the chances of androgen excess,PCOS,insulin resistance and hyperinsulinaemia.Obesity plays an important role in the pathogenesis of PCOS and obesity-associated metabolic alterations have a long-term impact on the patients' health.

Uterine leiomyoma is the most common benign tumour of reproductive system of wommen.In recent years,the mini-trauma technology represented by laparoscope and hysteroscope is popularized in the application to treatment of uterine leiomyoma,such as LH,LM,HM and UAE put forward recently,etc.They all have many advantages,little trauma,less pain,rapid recovery and shorter duration of hospitalization.But indication,method of operation and complication have nothing in common with each other.This text is a survey at the point.

The polycystic ovray syndrome(PCOS) is a heterogeneous condition with genetic predisposition. It is characterized by a myriad of symptoms including oligomenorrhea or amenorrhea,anovulation or infertility,hirsutism or acne. Insulin resistance appears to be an important factor in PCOS though the lack of an etiology has led to symptom oriented therapy which includes lifestyle modification,the use of cyclical progestagens and antiandrogens. Therapeutic approaches to PCOS remain an ongoing source of debate. Insulin sensitizing agents may bring new hope in therapy. Future research is aimed at shedding light on the pathophysiology so as to optimize treatment of women with PCOS.
