Objective: To observe the clinical effect of Sertraline in treatment of dysthymia. Methods:63 outpatients diagnosed as dysthymia according to ICD-10 were randomly assigned to study group (n=33) and placebo group. Randomized double blind control study was done for 8 weeks with Sertraline from 50-200 mg/d. HAMA and HAMD were used to assess the effect.Results:At the end of 8 weeks, 54 patients completed the trial. Patients of both groups had lower HAMD scores than baseline from 2 weeks, and this trend continued through the 8 weeks observation. During this period, HAMD score of the study group declined more significantly than that of the placebo group. At the end of 8 weeks, the score of HAMA of the study group was also lower than that of the placebo group. The side effects of Sertraline were mild.Conclusion:Sertraline is effective in treatment of psychiatric outpatients with dysthymia.

ObjectiveTo explore the clinical manifestations of infant cytomegalovirus infection in different age. MethodThe clinical data of 237 infants who suffered from cytomegalovirus infection was analyzed retrospectively and divided into three groups: 0-3 months old (77 cases,group A) ,4-6 months old ( 65 cases , group B ) , 7-12 months old ( 95 cases , group C ). ResultsThe incidence of respiratory infection was the highest among all infectious organs in three groups, the numbers of patients who had wheeze in group A was less than that in the other two groups[24.7％(19/77) vs. 61.5％ (40/65), 61.1％( 58/95 )](P ＜ 0.01 ).The incidence of jaundice decreased gradually as the babies grew up[23.4％( 18/77 )→7.7％(5/65 )→1.1％( 1/95 )](P ＜ 0.05). There was no significant difference in diarrhoea and bleeding among three groups (P＞0.05 ). The proportion of alanine aminotransferase], aspartate amino transferase increasing was similar among three groups, but gamma-glutamyl transferase (GGT) was different, the proportion of GGT increasing was 77.9％ (60/77) in group A which was higher than that in the other two groups[10.8％ ( 7/65 ), 2.1％ ( 2/95 )].Granulocytopenia in group B was obviously decreased compared with the other two groups (P ＜ 0.05 ), anemia was easily occurred in group C (P ＜ 0.05 ). ConclusionThe injury of cytomegalovirus infection may be related to month old.

Objective To explore the efficacy of the case and scenario teaching method in the neurosurgery practice teaching.Methods By cluster sampling,153 nursing students underwent rotary practice in neurosurgery department in People's Hospital of Three Gorges University from September 2011 to July 2012 were trained with the case and scenario teaching method.Scenario simulation training combined with case playback teaching was used in practice teaching.At the end of the internship,nursing students' satisfaction was investigated and their operational capacity was evaluated.Self-designed questionnaire was adopted to evaluate satisfaction.Operational capacity evaluation scores of nursing students were divided into several parts:basic operation examination (30％),specialized operation (30％),professional theory (30％) and teacher evaluation (10％).Data were analyzed using Excel spreadsheet for entry.Countif and Count function formula were used to calculate eligibility and the passing rate.Results Nursing students had high evaluation on case playback teaching methods.By this method,153(100％) nursing students considered that the learning initiative was improved.At the end of the internship,passing rates of basic operation examination,specialized operation,professional theory were 98.69％ (151/153),96.73 ％ (148/153) and 100％ while the total passing rate was 100％.Conclusion The case and scenario teaching method could develop the study positivity and practice ability of nursing students and can enhance the internship efficacy.

Objective To establish a guinea pig model for diagnostic reagent of tuberculosis.Methods By single or multiple subcutaneous injection of heat-killed H37 Rv in different doses in the groin of guinea pigs to establish a model of positive response to 0.1 mL (5 IU) standard tuberculin ( TB-PPD) skin test.Results Three doses of heat-killed H37 Rv ( 0.2 mg/mL, 0.3 mg/mL and 0.5 mg/mL ) could be used to generate the model of biological diagnosis of tuberculosis.After 24 and 48 hours, the diameter of red spot by TB-PPD skin test was 15.4 ±2.3 mm when a dose of 0.2 mg/mL heat-killed H37 Rv was administered for immunizing and allergizing the guinea pigs.The biggest red spot was induced at doses of 0.3 mg/mL and 0.5 mg/mL.The test results showed that the immune response induced by multiple njection to immunizing and allergizing guinea pigs was not significantly different than that induced by single immunizing injection, and the first skin test was better than the second, third and fourth skin test (P≤0.05).In addition, the body weight of the guinea pigs was still increasing after infection with heat-killed H37 Rv, and ulcers occurred in the injection sites in some guinea pigs.Conclusions A single subcutaneous injection of 0.2 mg/mL heat-killed H37 Rv in guinea pigs can be used well to establish a reliable model for biological diagnostic reagent of tuberculosis.Increasing the sensitizing dose and multiple sensitization can not increase the intensity of the delayed-type hypersensitivity ( DTH) response.

OBJECTIVEThis study aims to examine the expression of nuclear factor κB (NF-κB)/B cell lymphoma-2 (Bcl-2) signal pathway and glycogen synthase kinase 3β (GSK-3β) in oral squamous cell carcinoma (OSCC) and provide references for the early diagnosis and prognosis evaluation of OSCC.

METHODSA total of 55 cases of OSCC and 10 cases of paracan- cerous mucosa were examined in this study. Their expressions of GSK-3β, NF-κB and Bcl-2 were detected using the SP me- thod immunohistochemistry. The correlation between their expression in OSCC and the clinical and pathological peculiarity of OSCC was analyzed.

RESULTSThe positive expression of GSK-3β, NF-κB, and Bcl-2 in OSCC were significantly higher than that in paracancerous mucosa (P < 0.01). The expression of GSK-3β, NF-κB, and Bcl-2 had no obvious relationship with patient's age, sex, and clinical stages of the disease (P > 0.05). The expression of Bcl-2 was significantly correlated with the degree of tumor differentiation (P < 0.05), whereas the expression of GSK-3β and NF-κB in OSCC had no obvious relation- ship with the degree of tumor differentiation (P > 0.05). Strong positive correlations were observed among the expressions of GSK-3β, NF-κB, and Bcl-2 (P < 0.05).

CONCLUSIONThe positive expression of GSK-3β, NF-κB, and Bcl-2 in OSCC are sig- nificantly higher than that in paracancerous mucosa. Detecting GSK-3β, NF-κB, and Bcl-2 in OSCC may have implications in the early diagnosis and prognosis evaluation of OSCC.
