Objective To observe the effect and safety of modified Yishen Zhuyang Huoxue Huazhuo Formula for polycystic ovarian syndrome (PCOS) in the TCM pattern of deficiency of spleen and kidney with phlegm-dampness. Methods Totally 123 cases were recruited into this study and randomized to two groups by central random approach, 64 cases in the observation group and 59 cases in the control group. Patients in the observation group were given the modified Yishen Zhuyang Huoxue Huazhuo Formula, while those in the control group were given compound cyproterone acetate tablet, for two treatment courses, three months for one course. The changes of ovarian volume and the number of follicles before and after treatment were observed. Adverse reactions were also evaluated. Results Bilateral ovarian volumes in both groups decreased after treatment (P<0.05, P<0.01), while the control group showed a significant better improvement (P<0.05). The number of follicles in the two groups decreased, but no significant difference were observed between the two groups (P>0.05). The rate of adverse reaction in the observation group was lower than the control group. Conclusion Modified Yishen Zhuyang Huoxue Huazhuo Formula is effective for PCOS patient by reducing the ovarian volume with a low incidence of side effect.

Objective: To improve the diagnosis and treatment level of secretory otitis media (SOM) of children. Method :Clinical information of 80 children with SOM were colletcted and analysed. All of the 80 cases (144 ears)were treated by myringotomy with Grommet insertion. Among them, 30 cases by adenotonsillectomy. 10 cases by palatoplasty. Secretions of 54 ears were carded out by bacterial culture. Result:80 cases were followed up for 6 to 12 mothes. 120 ears of 144 were cured (83％) ,with hearing improved. The tympanograms and hearing threshold of pure tone were found to be normal. The Gram＇s positive and negative germs of bactevial culture were 20.7％ (6/29 samples ) and 24％ (6/25 samples ) respectively. Conclusion: Children with secretory otitis media should be treated as early as posible to improve the patients＇ hearing and develope their speech.

Pertussis is an severe infectious respiratory disease that continues to be a serious public health problem,which is caused by Bordetella Pertussis.Because it's highly infectivity,it is still an important etiological factor associated with persistent cough in adults and adolescents.With the introduction of mass vaccination in 1974,there has been a dramatic decrease in the morbidity and mortality.However,in recent years,increasing numbers of pertussis are reported in adolescents and adults in many countries where with high vaccination coverage.The thesis summarize and discuss the progress of pertussis cpidemiology and clinical characteristics.

Abstract: Relapse and metastasis are the main causes responsible for failure of surgical operation in treating malignant tumors. This article introduces the present development in post-operation treatment of lung cancer, liver cancer and stomach cancer, showing that the synthetic treatment by stages combined with traditional Chinese medicine is the important way to prevent and treat the post-operation relapse and metastasis of tumors, and suggesting the optimized method for treatment.

At present,in the opinions of the domestic and foreign scholars,the only hope of long-term survival even cure of hilar cholangiocarcinoma was obtained by radical resection(ie R0 resection).The application of preoperative assessment with appropriate and comprehensive strategies can judge the respectability and Intraoperative safety accurately to the tumor,thereby it can improve the radical resection rate and safety of patients with hilar cholangiocarcinoma.In this paper,preoperative assessment strategies are reviewed.

Objective To analyze the genetic diversity of snail populations from five provinces in China mainland. Methods Genomic DNA was amplified by random primer and the products were electrophoresed by 8% polyacrylamide and stained by 0.6% silver nitrogen. The results were recorded and analyzed. Results The average similarity and match percentage among the nine snail populations were 0. 721 4 and 0. 680 9 respectively. The cluster trees showed that the nine snail populations could be divided into three groups ; snails from Dali of Yunnan Province and Puge of Sichuan Province were the first isolated group; snails from Fuqing of Fujian Province and Dongtai of Jiangsu Province were clustered into the second group; the other four populations from Anhui Province and snails from Yixing of Jiangsu Province belong to the last group. Conclusion There is a large diversity among smooth-shelled snails in China although close relationship exists. The cluster trees gained by different snail populations are basically the same and consistent with the distribution of these populations. However, further study should be carried out on the cluster of smooth-shelled snails from Dongtai of Jiangsu Province.

Comprehensive evaluation for colleges of stomatology is a complex systematic engineering, which is affected by the determination of index and weight. Based on the previous research results,this study establishes a comprehensive evaluation index for colleges of stomatology in China by applying Delphi method,carrying out two-round consultation to 45 experts,which includes 4 first layer indicators and 21 second layer indicators.

[Objective]To evaluate the application of sonographic measurements of the thickness of transverse carpal ligaments in CTS(carpal tunnel syndrome) patients.[Methods]Fifty-two wrists from 40 patients with CTS confirmed by surgery and 32 wrists from 20 healthy individuals(control group) underwent sonographic examination of the thickness of transverse carpal ligaments at the level of pisiform bone and the hook of the hamate bone in transverse plane by the same operator.[Results]The thickness of transverse carpal ligaments in CTS patients was(0.41?0.10) cm at hamate hook level and(0.35?0.11) cm at pisiform level versus(0.28?0.11) cm and(0.20?0.08) cm in the control group.There was significant difference in the mean value of thickness of transverse carpal ligaments hetween the two groups at the two levels.[Conclusion]Ultrasonography examination of the thickness of transverse carpal ligaments is a new and valuable technique in the diagnosis of carpal tunnel syndrome and is much helpful to choose operation methods.

Objective The clinical effect of Allitride as disinfectant in infective root canal of deciduous teeth was studied. Methods 40 teeth were put into the cotton thist with Allitride juice in root canals,sealed by zno for a week. FC CP were used in the contrast groups with consist of 38 teeth. Results The effect of 24 teeth in the Allitride group were excellent, 13 teeth were benign, The efficiency was 92 percent. In CP group, 8 teeth were excellent, 5 teeth were benign, The efficiency was 72 percent. 11 excellent effect and 7 benign effect were in FC group. The efficiency was 90 percent. There are significant difference between Allitrade group and GP group(P0.05). The Allitride effect have not significant relation with age, tooth position.Conclusions Allitride is a good disinfectant adapt to infective root canal of deciduous teeth.
