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.

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.

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.

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.

[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.

0.05), and there was significant differences in the negative score of PANSS (t=6.13, P

Objective To observe the clinical cure effect of Zhilong Tongluo Decoction on chronic obstructive pulmonary disease in acute exacerbation(AECOPD). [Method] Take prospective research method to randomly divide 70 cases of AECOPD into 2 groups, the control one(35 cases) take routine western medicine(WM) for treatment, the treatment group(35), added with Zhilong Tongluo Decoction on the basis of control one. After being treated for 14d, compare their PH value, PaO2, PaCO2, HCT, ESR, CRP and clinical effect and side effects before and after treatment. [Result] The comparison of both groups had no difference of statistical meaning on PH,PaO2,PaCO2,HCT,ESR,CRP; after treatment, the PH and PaO 2 markedly increased, PaCO2 obviously decreased(P<0.05), so did HCT,ESR,CRP(P<0.05,P<0.01); the treatment group was much better than control one on improvement, so was the effective rate. Both had no marked side effects. [Conclusion] Zhilong Tongluo Decoction controls inflammation and improves ventilation and blood flow with its Tongluo(stretch col aterals), having obvious effect on AECOPD.
