Objective To evaluate the efficiency and safety of mifepristone and gestrinone in subsidiary treat- ment after endometriosis surgery.Methods Totally 151 patients diagnosed as endometriosis with conservative surgery treatment or laparoscopic operation were divided into three groups;49 cases in the group of mifepristone re- ceived mifepristone tablets 10mg every day for 6 months from the first week of postoperation,60 cases in the group of gestrinone received gestrinone capsules 2.5mg twice every week for 6 months.Cases in the group of control did not receive any postoperative medical treatment.The duration of follow-up after surgery was censored at 3～18 months.Patients'controlling rate of ache symptoms and signs,clinical efficiency,recurrence rate,sex hormone level, menstrual and weight changes,liver and renal functions were recorded and compared.Results The follow up rate is 97.4 %,the efficacious rate and symptoms controlling rate of mifepristone group and gestrinone group were 78.7 %, 93.1% respectively,which of the control group were 34.8 %,58.7 % respectively.There were significant differ- ences,x~2=44.31,P

Objective To explore the application of ABCD3 score on stratifying the antithrombotic treatment strategy in patients with capsular warning syndrome (CWS).Methods The clinical features of 15 patients with CWS were analyzed retrospectively,and the risk of stroke were evaluated by ABCD3 score and to guide the treatment of Stratifying antithrombotic therapy.The status of patients hospitalized,discharged and discharged after 90 d were evaluated.Results The frequency of patients with CWS accounted for 2.51％ (15/ 597) of all patients with transient ischemic attack(TIA),and the mean age in patients with CWS was (70.27 ±8.29) years old.The duration of the first onset was (10-30) min,the mean time was (17.33±1.53) min,and ABCD2 score was 5.0-9.0 points,mean score was 7.00±0.26 points,and the total episodes of CWS were 51 times during 24 hours,the mean duration was (18.13 ± 15.36) minutes ((3.0-60.0) min).All 15 cases presented with limb hemiparesis.Of them,9 cases had dysarthria,5 case with ipsilateral facial palsy.All 15 cases CWS patients showed no signs of cortical deficit.The mean NIHSS score at onset was 1.0-6.0 points,mean scores was 3.20±0.31 points.Fourtheen patients were treated with clopidogrel plus aspirin,and 2 cases with administration of the loading dose 300 mg of clopidogrel,1 case was treated with clopidogrel plus aspirin orally followed by intravenous rt-PA thrombolysis.The average hospital periods of all 15 patients was (7.67±0.29) days.The NIHSS score were 0 point at discharge.There was no symptomatic intracranial hemorrhage or death within 90 days follow-up periods.Conclusion CWS is prone to develop a completed stroke.Stratified antithrombotic therapy guiding by ABCD3 score may decrease the risk of ischemic stroke.

Objective To analyze the clinical characteristic and prognosis of Serratia infections in newborn infants and increase awareness of Serratia infections.Methods The clinical manifestations,diagnosis,complications,treatment and prognosis of Serratia infections were analyzed in 4 hospitalized newborn infants in neonatology center from Jul.2008 to Feb.2009.Results Among the 4 cases,blood culture revealed Serratia marcescens in 3 cases(1 case was preterm infant),cerebral spinal fluid culture revealed Serratia liquefacien in the fourth case.The main clinical manifestations were fever,convulsion and poor response,WBC and CRP were much higher,while obvious thrombocytopenia was only found in the preterm infant.Two cases of septicemia infection alone recovered after the treatment of the third-generation cephalosporin for at least 2 weeks,while the other 2 cases of septicemia infection combined with purulent meningitis,included 1 case of preterm infant and 1 case of Serratia liquefacien infection,developed meningoencephalitis and brain abscess confirmed by serial imaging,both of which had poor neurological sequelaes.Conclusions As a opportunistic pathogen,Serratia can cause severe infection in newborns.The patients complicated with meningitis should be followed up and pay more attention to the high incidence of neurological sequelaes.

OBJECTIVETo explore the effect of Qiling Decoction (QD) combined highly active antiretroviral treatment (HAART) on expression levels of peripheral blood Th17 and Treg cells in HIV/AIDS patients.

METHODSTotally 55 HIV/AIDS patients were randomly assigned to the treatment group (28 cases) and the combination group (27 cases). Besides, 21 HIV negative patients were recruited as the healthy control group. Those in the treatment group received HARRT alone, while those in the combination group received HAART combined QD. The observation lasted for 24 weeks. Meanwhile, according to peripheral blood CD4+ T cell counts before treatment, HIV/AIDS patients were assigned to three subgroups. For patients in subgroup 1, 1 cells/microL < CD4+ T cell counts < or = 100 cells/microL; For patients in subgroup 2, 101 cells/microL < CD4+ T cell counts < or = 200 cells/lL; For patients in subgroup 3, 201 cells/microL < CD4+ T cell counts < or = 350 cells/microL. Expression of peripheral blood Th17 and Treg cells, and number of CD4+ T cell counts were detected using flow cytometry (FCM)in HIV/AIDS patients at the pre-treatment baseline, week 4, 12, and 24, as well as those in the healthy control group.

RESULTSCompared with the healthy control group, CD4+ T cell counts and the baseline expression level of Th17 cells in the peripheral blood of HIV/AIDS patients significantly decreased, the expression level of Treg cells significantly increased P < 0.01). Compared with before treatment in the same group, CD4+ T cell counts all increased at week 4, 12, and 24 in the two treatment groups, showing statistical difference (P < 0.05, P < 0.01). There was no statistical difference in the effective rate at various CD4+ T cell levels between the two groups (P > 0.05). There was no statistical difference in expression levels of Th17 and Treg cells between the combination group and the treatment group at any time point (all P >0.05). The Th17/Treg ration significantly increased in the combination group after 24 weeks of treatment, showing statistical difference when compared with the treatment group (U = 2.135, P = 0.038).

CONCLUSIONQD could improve the immune balance of Th17/Treg cells, which might be one of its mechanisms for improving HIV/AIDS patients' immunity.

OBJECTIVE: To establish 2-dimensional electrophoresis (2-DE) maps of Helicobac-ter pylori in human gastritis, and gastric cancer, to identify the differentially expressed proteins,and to discuss the role of bacterial factor in pathogenesis. METHODS: The total proteins of Helicobacter pylori in human gastritis and gastric cancer were separated by immobilized pH gradient-based 2-DE. The differentially expressed proteins were screened by PDQuest analysis software and identified by peptide mass fingerprint based on matrix-assisted laser desorption/ionization time of flight mass spectrometry, and searched on database. RESULTS: A well-resolved and reproducible 2-DE pattern of Helicobacter pylori was obtained from patients with human gastritis and gastric cancer. Fourteen differentially expressed proteins were identified, including proteins related to anti-oxidation,molecular chape-rones and detoxification, enzymes related to metabolism,proteins related to cytoarchitecture,and proteins related to signal conduction. CONCLUSION A well-resolved and reproducible 2-DE pattern of Helicobacter pylori in human gastritis and gastric cancer is established and differentially expressed proteins from these 2 diseases are identified. The differentiation of protein expression may play an important role in the pathogenesis of gastric cancer.

Objective To investigate the attitudes of urban and rural community members toward total banning on smoking in public places and to explore the factors associated with these attitudes, in three counties/cities in China. Methods A cross-sectional study was conducted in three counties/cities in 2004, including Xin' an county of Henan province, Anyi county of Jiangxi province, and Mianzhu city of Sichuan province. A total of 5642 residents at age of 18-69 years old were interviewed face-to-face with a uniform questionnaire by locally-trained interviewers, through a random three-stage stratified sampling in each county. Factors were assumed to be associated with attitudes, using chi-square test in univariate analysis and non-conditional logistic regression model in multivariate analysis. Results The prevalence of current smoking among respondents was 44.3%. 80.7% (1379/1709) of the current smokers reported smoking often or sometimes in public places. Only 9.6% (479/4983) of the respondents reported that their indoor workplaces had totally banned on smoking. 43.5% of the respondents supported a total smoking ban strategy in pubic venues. The results of multivariate logistic regression model showed that eight factors were significantly associated with support for the total smoking ban in public places included region, residency, age, gender, education, smoking status, awareness about passive smoking hazards, and hearing of any message on tobacco control through media differences of rates regarding the factors as: residents in urban to rural areas (OR=1.29), elderly to youngsters (30-49 vs. 18-29, OR=1.46; 50-69 vs. 18-29, OR=1.71), female to male(OR=1.27), high-educated to less-educated ones, quitters to current smokers (OR=1.90), nonsmokers to current smokers (OR=2.01). Those who know messages on health hazards of passive smoking (OR=2.26), or heard of message on tobacco control through media (OR= 1.43). Conclusion Results from our study revealed that a thorough smoke-flee policy in public places should be developed and implemented in these three counties/cities.
