Objective To investigate the characteristics of the preoperative and postoperative urodynamical parameters of women with uterine cervical carcinoma after radical hysterectomies.Methods Forty-six women had uterine cervical carcinoma at stage Ⅰ b or Ⅱ a.Complete pre-and postoperative urodynamie follow-ups were conducted for each patient.Results Twenty-six women(57%)who had preoperatively normal urinary tract function needed to void by abdominal straining after radical surgery.After the radical hysterectomy,the postvoid residual volume[(205?201)vs(5?3)ml,P

Shanghai University of TCM was the first Chinese medicine university that established field-grade experimental teaching center in China.And both of the Chinese medicine and Chinese herbs experimental teaching centers became national experimental teaching demonstration centers.There is general improvement in laboratories conditions,so the experimental teaching team building is the critical factor of improving experimental teaching quality.The experimental teaching team of Shanghai University of TCM consists of excellent teachers as its backbone,and lecturers and technicians from fields in traditional Chinese medicine Chinese herbs and clinical practices.The team members cooperate with each other by setting up experimental teaching research groups to improve teaching quality,which plays an important role in building experimental teaching demonstration center.

Objective To explore the influence of lamotrigine(LTG)and valproate(VAP)on cognitive function in children with epilepsy.Methods Seventy-six epileptic children firstly diagnosed were chosen,36 cases received LTG monotherapy and 40 cases undwent the treatment of VPA.The intelligence quotient(IQ)value was measured before and after 6 months treatment respectively,and 20 healthy children were selected as healthy control.Results 1.The epileptic children had poor verbal intelligence quotient(VIQ),performance intelligence quotient(PIQ)and full intelligence quotient(FIQ)compared to the control subjects(Pa0.05).But among the subtestings,the know-ledge,wood-graph,coded score of the VPA groups had significant difference(Pa

Aspergillus oryzae is an important microorganism,which was widely used in the fields of food,brewing,pharmacy and fermentation industry etc and was termed as a generally regarded as safe(GRAS) organism by the United States Food and Drug Administration(FDA).The strategies for promoting the expression of homologous and heterologous proteins in Aspergillus oryzae were reviewed.Which included the usage of strong promoters,multicopies of coding genes,optimization of culture medium and overexpression of the hemoglobin domains(HBD) etc.Heterologous proteins were usually exhibited low expression in Aspergillus oryzae due to the degradation by the proteinases from host.Therefore,development of proteinase auxotrophic stains of Aspergillus oryzae as host is neccessary.In addition,fusion of the heterologous protein with a highly secreted protein of Aspergillus oryzae was an alternative way to prompt the expression of heterologous protein in Aspergillus oryzae.

Drug reservation wag investigated in 2077 community residents.We found that most drugs were obtained from the hospitals(83.78%),kept at a relatively lower place(69.23%),packed in box(75.25%),and did not meet the storage requirement(72.60%).Half of the overdue drugs(median time,12 months)were used for internal treatment.This study suggests that there might be unsafe drug storage in communities.

ObjectiveTo evaluate the diagnostic performance of CTCA in predicting myocardial perfusion defects through comparative analysis between MPI defects and severity of coronary stenosis on CTCA.MethodsFour hundred and seventy-eight patients who underwent CTCA and 99Tcm-MIBI MPI in the same period were analyzed retrospectively.According to the severity of coronary stenosis judged by visual evaluation of the vessel diameter,the patients were divided into five groups:no stenosis,mild stenosis,moderate stenosis,severe stenosis and total occlusion.MPI results were classified as negative or positive for perfusion defects,and the prevalence of perfusion defects in every group was calculated per-patient and per-vessel basis.The cut-off of stenotic severity for predicting myocardial perfusion defects was designated as 50％ or 75％,with MPI as standard reference.True positive,true negative,false positive and false negative statistics were thus determined separately on patient and vessel basis.The diagnostic performance for CTCA were calculated and compared.Pearson Chi-square and its partition tests or Fisher exact test were used to compare ordinal variables.ResultsFifty-eight patients showed myocardial perfusion defects.Either by patientbased or vessel-based analysis,the prevalence of myocardial perfusion defects showed an increasing trend with greater coronary artery stenosis in each group,and there were statistical differences among them (x2 =116.62 and 483.83,both P ＜ 0.05).On patient-based analysis,sensitivity ( SN),specificity ( SP),positive predictive value( PPV),negative predictive value(NPV) and accuracy (AC) for CTCA predicting myocardial perfusion defects were 62.1 ％ ( 36/58 ) and 34.5％ ( 20/58 ) (x2 =8.84,P ＜ 0.05 ),84.5％(355/420) and 97.1％ (408/420) (x2 =40.16,P ＜0.05),35.6％ (30/101) and 62.5％ (20/32) (x2 =7.19,P＜0.05),94.2％ (355/377) and 91.5％ (408/446) (x2 =2.18,P ＞0.05),81.8％ (391/478)and 89.5 ％ (428/478) (x2 =11.66,P ＜ 0.05 ) when the cutoff was set to 50％ and 75％,respectively.On vessel-based analysis,the SN,SP,PPV,NPV and AC for CTCA predicting myocardial perfusion defects were 58.8％ (40/68) and 30.9％ (21/68) (x2 =10.73,P ＜ 0.05),95.9％ (1768/1844) and 99.0％ (1826/1844) (x2 =36.72,P ＜ 0.05 ),34.5％ (40/116) and 53.8％ (21/39) (x2 =4.59,P ＜0.05 ),98.4％ (1768/1796) and 97.5％ ( 1826/1873 ) (x2 =4.14,P ＜ 0.05 ),94.6％ ( 1808/1912 ) and 96.6％ ( 1847/1912 ) (x2 =10.31,P ＜ 0.05 ),respectively.ConclusionsThe prevalence of myocardial perfusion defects correlates positively with the severity of coronary stenosis seen on CTCA.CTCA may predict perfusion defects with high SP and NPV.However,the PPV of CTCA in predicting myocardial perfusion defects is poor when the stenosis cut-off is set at 50％.It is significantly improved when the cutoff value is set at 75 ％.

OBJECTIVE: To summarize the pattern and main characteristics of fatal cases related to medical disputes in Yancheng area. METHODS: Sixty fatal cases of medical disputes were retrospectively analyzed to elucidate the annual incidence, characters of distribution of hospitals, gender and age of the decedents, types of diseases, and cause of death. RESULTS: Among 60 fatal cases, most cases happened in health clinics of county, township and village. There were more males than females. The major medical specialties involved included internal medicine, surgery, gynecology and pediatrics, with the internal medicine specialty having the highest incidence. CONCLUSION Police institutions have advantages in investigation of these cases in their jurisdictions, which could enhance the ability of local medicolegal examination.

OBJECTIVETo investigate the effects of Er Xian Decoction (EXD) and its three subdivisions "warming Shen" ,"nourshing Yin" and "adjusting Chong and Ren" in regulating the level of estradiol (E2) on the primary cultured granulosa cells.

METHODSEffect of EXD and its three subdivisions, also part of the effective components of this formula, icariin and curculigoside, on level of E2 were carried out using primary cultural granulose cell as the experimental model.

RESULTEXD and its three subdivisions could stimulate the secretion of E2, especially the "warming Shen" group (P <0.05). All the composing of Chinese herbs of this formula could promote the level of E2 in different degree, and the Rhizoma Curculiginis, Radix Moromade Officinalis, and Herba Epimedii have the best effects (P <0. 01).

CONCLUSIONThe regulation of EXD on the hypothalamus-pituitary-gonad (HPG) axis may be related to promoting the secreting of E2 at the site of granulosa cell. The "warming Shen" subdivision has the better effect in promoting the secretion of E2.
