Assay .The viral load of HBV‐DNA reactive sample was quantitatively determined .Results Among 9 143 blood samples ,2 213 samples were HBV‐M negative ,and the negative rate was 24 .20% .The negative rate of male to female was 1∶1 .21 .Using chemiluminescence immunoas‐says and PROCLEIX ULTRIO? Assay simultaneously ,we found one case of low concentration of HBsAg(both HBsAb and HBV DNA nonreactive) ,four cases of low concentration of HBsAb(both HBsAg and HBV DNA nonreactive) ,two cases of HBV‐DNA reactive(HBV‐M negative) .One HBV‐DNA reactive sample could be quantified as 560 IU/mL .Conclusion In HBV‐M (ELISA) negative population of health examination of Hangzhou district ,a few subjects had low concentrations of HBsAg or HBsAb or HBV‐DNA .For HBV‐M negative population ,quantitative detection of HBV‐M and HBV‐DNA before HBV vaccination is recom‐mended to determine w hether they need HBV vaccine and the HBV vaccination plan .

Objective To study the feasibility of re-operation of gynecological laparoscopy.Methods Clinical records of 47 patients with gynecological diseases undergoing a re-laparoscopy from December 1995 December 2003 were analyzed retrospectively.Results The re-operations of laparoscopy were successfully accomplished in 46 patients(97.9%) while a conversion to open surgery was required in 1 patient.The re-operation time was 30~80 min(mean,50 min),and the in-hospital stay was 2.5~5 days(mean,3.5 days).No long-term complications were noted in 44 patients on a postoperative follow-up for(1~4) years.Out of 19 patients with infertility, 1 patient had a natural pregnancy and 6 patients were pregnant with the help of artificial reproductive techniques.Supportive medical treatment had been given in patients with endometriosis postoperatively,3 of whom experienced symptomatic improvements and 1 of whom had a natural pregnancy.Conclusions For patients with a history of laparoscopy,a re-operation of gynecological laparoscopy is safe and feasible.

Objective To investigate the effects ofZhenqi-Fuzheng capsule combined with highly active antiretroviral therapy (HAART) the Thl/Th2, Tcl/Tc2, and CD4+ T lymphocytes in patients with advanced AIDS.Methods A total of 70 patients with advanced AIDS were randomly divided into a treatment group and a control group, with 35 patients in each group. The treatment group was treated withZhenqi-Fuzheng capsule combined with HAART, while the control group was treated with HAART only. The patients in both groups were treated for 24 weeks. The Thl, Th2, Tcl, Tc2 and CD4+ T lymphocytes in peripheral blood were detected by flow cytometer.Results After treatment, the ratios of Th1/Th2 (6.27 ± 0.70vs. 5.39 ± 0.64;P<0.05) and Tcl/Tc2 (10.70 ± 0.68vs. 10.16 ± 0.85;P<0.05) in the treatment group showed significantly higher than those in the control group. The CD4+T lymphocytes after the treatment in both groups showed significantly increased than that before the treatment (treatment group: 289.2 ± 101.5/mlvs. 121.1 ± 77.5/ml,P<0.01; control group: 231.6 ± 97.6/mlvs. 118.9 ± 76.2/ml,P<0.01). The CD4+T lymphocytes in the treatment group showed significantly increased than that in the control group after the treatment (P<0.05).ConclusionsZhenqi-Fuzhengcapsule combined with HAART may regulate the Thl/Th2 and Tcl/Tc2, and increase the CD4+ T lymphocytes in patients with advanced AIDS.

Objective:To develop a Child School Refusal Behavior Rating Scale(SRBQC)and examine its reliabilities and validities. Methods:Based on literature review,interview,and open-ended questionnaire,124 origi-nal items were developed. Totally 573 students were recruited to complete the test version. After item and explorato-ry factor analysis,the formal scale-SRBQC was got. Totally 946 students were tested with formal version for further confirmatory factor analysis,internal consistency reliability and composite reliability. The criterion validity was test-ed with the Social Anxiety Scale for Child (SASC). Totally 41 students were retested for test-retest reliability with 2 weeks interval. Results:The formal version of SRBQC included 19 items. Exploratory factor analysis generated 5 factors which account 59. 793% of the variance in all,the results of confirmatory factor analysis showed that SR-BQC had a good construct validity (χ2 =329. 51,df=142,χ2/df=2. 32,CFI=0. 97,GFI=0. 93,IFI=0. 97,NFI=0. 95,NNFI=0. 96,RMSEA=0. 05,SRMR=0. 05). The SRBQC scores were positively correlated with the SASC scores (r=0. 18-0. 34,Ps<0. 05 ). The Cronbach coefficients were 0. 87 for the total questionnaire and 0. 55 -0. 78 for the 5 factors. The test-retest reliabilities were 0. 84 for the total questionnaire and 0. 66 -0. 78 for the 5 factors. Conclusion:The reliability and validity of the School Refusal Bevior Questionaire for Children(SRBQC) meet the needs of psychometrics.

Objective To study the effects of pravastatin sodium on the release and activity of neutrophil elastase ( NE) in human neutrophile granulocyte induced by lipopolysaccharide( LPS) . Methods Human neutrophile gran-ulocyte were isolated by Ficoll density gradient centrifugation, neutrophils and intracellular azurophilic granules were identified by myeloperoxidase( MPO) staining, LPS stimulated degranulation of neutrophils. The MPO activity in the supernatant was measured by colorimetric assay to determine the appropriate stimulus time and concentration, and neutrophil was treated with pravastatin sodium after LPS stimulation. ELISA mothed was used to detect the cell culture supernatant of NE content and NE activity was detected by colorimetric method. Results The content and activity of NE in the supernatant were significantly increased after LPS stimulation. The NE in the supernatant of the cells treated with pravastatin was significantly lower( P＜0.05) . Conclusion Pravastatin sodium can reduce neutrophil degranulation induced by LPS stimulation and decrease the release and activity of NE.

Objective To investigate the changing trend and correlation of platelet count and spleen diameter in patients with digestive system malignancy receiving oxaliplatin-based chemotherapy. Methods We retrospectively analyzed clinical data of 72 patients with digestive system cancer, recorded and analyzed platelet count and spleen diameter during and after oxaliplatin-based chemotherapy. Results The incidence of thrombocytopenia in all patients was 65.3%. The median time of thrombocytopenia after the beginning of chemotherapy was 2.53±0.49 months, and the median cumulative dose of oxaliplatin was 520±35.81 mg/m²; the median time of lowest platelet count after the beginning of chemotherapy was 4.03±0.49 months, and the median cumulative dose of oxaliplatin was 780±36.32 mg/m². Splenomegaly occurred in 52(72.2%) patients during the follow-up. The median increase rate was (18.82±0.01)%. The median time of splenomegaly after the beginning of chemotherapy was 2.15±0.19 months, the median time for the largest spleen diameter was 4.68±2.89 months; after the end of chemotherapy, the median time for spleen contraction was 3.28±0.44 months, and the median time for spleen recovery was 8.80±1.05 months. Conclusion Oxaliplatin-based chemotherapy can cause thrombocytopenia and splenomegaly, and it is difficult to recover to baseline for a long time after the end of chemotherapy. The increase of spleen diameter was positively correlated with splenomegaly and thrombocytosis.
