Objective: To sum up characteristics of hotline counseling about mental health problems in Shanghai. Method: All records of hotline counseling from 1990 to 2000 were input into computer. Retrospective analysis was done. Results: In the past 10 years, the main issues in hotline counseling were associated with love affairs (18.1%), emotional troubles (15.8%), psychosis (11.3%), and interpersonal relationship (8.1%), which were also related to the help-seekers background, such as gender, age, education levels, occupation and marriage status.

Objective:To observe the effect of the proteininhibitor of activated STAT 3 (PIAS3) on the proliferation and apopto-sis of U251 glioma cells after PIAS3 expression was inhibited by RNAi. Methods: Three RNAi expression vectorstargeting PIAS3 were constructed and transfected into CHG-5 cells by liposomein vitro. The most efficient RNAi vector was subsequently selected by examiningthe mRNA expressions of PIAS3 in the transfected cells by semi-quantitativeRT-PCR. The selected RNAi vector was then transfected into U251 cells. After 48h of transfection, the mRNA and protein expressions of PIAS3 in glioma cellswere examined by semi-quantitative RT-PCR and western blot. Apoptosis wasobserved by flow cytometry using a double-staining method with FITC-con-jugatedannexin V and PI. Flow cytometry was also applied in cell cycle assay. Results:RNAidownregulated the mRNA (P<0.01) and protein (P<0.01) expressionsof PIAS3 in transfected cells.RNAi promoted the resistance of U251 cells to apoptosisand subsequently al-tered the cell cycle. A high percentage of G2 phaseand a low percentage of Sphase were observed in U251 cells. Conclusion:The down-regulation of PIAS3arrested U251 cells in the G2 phase andinduced the resistance of U251 cells to apoptosis.

Objective To investigate the effect of pronuciferine on apoptosis of cultured human umbilical vein endothelium cells(HUVECs) induced by angiotensin Ⅱ(AngⅡ).Methods HUVECs cell line ECV304 was cultured in vitro,pretreated with Captopril(10 ?mol/L) or pronuciferine 10,1,0.1,0.01 ?mol/L for 30 min,respectively,then treated with AngⅡ(1 ?mol/L).Cell-morphosis was observed by light microscope.Cells viability was assessed by MTT assay.Production of nitric oxide(NO),activities of total nitric oxide synthase(tNOS),and inducible nitric oxide synthase(iNOS) were measured by colorimetry.Apoptosis rate was measured by Flow Cytometer(FCM).Results AngⅡ induced typical endothelial cell apoptosis and the apoptosis rates were significantly higher than those of the control group((P

Objective To clone and study the antimicrobial-resistant gene in Neisseria gonorrhoeae.Methods The gene library,which contains the differential genes of antimicrobial resistant strains and stan-dard reference strains of Neisseria gonorrhoeae,was constructed using a technique known as suppression subtractive hybridization(SSH).Then the antimicrobial resistance associated genes were cloned and ana-lyzed.Results Subtractive gene library in antimicrobial-resistant Neisseria gonorrhoeae was successfully constructed,which contains2500positive clones.Sequence analysis was performed on5clones.The se-quences of these five clones were unknown previously.Conclusions The subtractive DNA library is succes-sively constructed which may provide an important clue for studying the mechanism of antimicrobial resis-tance in Neisseria gonorrhoeae.

Objective To investigate the correlation between executive function(EF) and characteristic of symptom in children with Tourette′s syndrome(TS).Methods EF were measured with Wisconsin Card Sorting Test(WCST) in 53 patients with TS,and symptom characteristics were evaluated with Achenbach Child Behavior Checklist(CBCL) and Yale Global Tic Severity Scale(YGTSS).Results Compared with healthy control,TS had poor executive performances significantly in WCST(all P

The effects of different concentrations of vascular endothelial cell growth factor (VEGF) on the fibrovascular ingrowth into rabbits hydroxyapatite orbital implant were investigated. Twelve New Zealand white rabbits were divided into 3 groups and received hydroxyapatite orbital implant surgery in their right eyes. Before and after the operation, the implants were treated with 10 ng/ml VEGF, 100 ng/ml VEGF, or normal saline as control group. The animals received technetium bones scan at 2, 4, and 6 weeks postoperatively. The mean radioactivity counts within region of interest (ROI) of the surgery eye (R) and the non-surgery eye (L) in the same animal were tested, and the R/L ratios were calculated. The implants were harvested at 6th weeks and examined histopathologically. The results showed that at second week, there was no significant difference in mean R/L ratios between VEGF group and control group (F=2.83, P=0.111); At 4th week (F=7.728, P=0.011) and 6th week (F=7.831, P=0.011) postoperatively, the mean ratios in VEGF groups were significantly higher than that in control group. At 6th week postoperatively, the fibrovascularization rates in VEGF groups were higher than in control group significantly (F=8.711, P=0.008). It was suggested that VEGF could promote the fibrovascular ingrowth into hydroxyapatite orbital implant, thus might shorten the time required for complete vascularization of the HA orbital implant.
