Objective To study the effect of anti-hepatitis B virus of Lamivudine combined with Saikosaponins in vivo. Methods Chongqing duck hepatitis B model was selected and given to Lamivudine combined with Saikosaponins(combined group) oral treatment 28d, then the ducks were observed 7d after drug withdrawal. The levels of serum HBV DNA, HBsAg and transaminase(ALT, AST) were detected before and after treatment, and compared with that in Lamivudine group and Saikosaponins group as control. Results In combined group,the levels of serum HBV DNA and HbsAg were significantly decreased(P ＜ 0.05), and 7d after drug withdrawal the levels of serum HBV DNA and HBsAg showed no" anti-jump" compared with that at drug treatment 28d(P ＞ 0.05). In Lamivudine group and Saikosaponins group the levels of those increased again 7d after drug withdrawal (P ＜ 0. 05). In each group the levels of serum ALT and AST did not change within the same phase during drug treatment 28d and 7d after drug withdrawal(P ＞ 0. 05). Conclusion Lamivudine combined with Saikosaponins in vivo had the effect of anti-hepatitis Bvirus, and the effect was stable and lasting.

Objective To investigate the underlying causes, clinical characteristics, treatment and prognosis of non-traumatic pneumomediastinum (PM) in children. Methods A retrospective analysis of the clinical data of 64 children diagnosed with non-traumatic PM in Yuying Children’s Hospital Affiliated to Medical University from Jan 2003 to Dec 2013 was performed. Nineteen children with SPM and the other 45 with clear causes of non-traumatic PM were divided into two groups for comparison. According to age, 64 cases were divided into 0-6y group and 6-18y group for further comparison. Results A total of 64 patients with non-traumatic PM were collected. Nineteen of them aged 14.90±2.00 y had SPM with unknown etiology, and 84.2%were male. The other group of 45 patients aged 4.26±4.45y, and 55.6%of this group were male. The common causes were pneumonia or other lower respiratory tract infection, asthma and foreign body inspiration. The patients with SPM were always with chest pain. While the patients with clear causes of non-traumatic PM were more complained of dyspnea, coughing, subcutaneous emphysema. The treatment of patients with SPM was bed rest, oxygen uptaking, antitussive, anti-infection and other conservative therapy. All the patients with clear causes of non-traumatic PM had favorable prognosis with the treatment of actively curing primary disease and timely mediastinal air drainage, subcutaneous air drainage and thoracic close drainage. In 35 cases younger than 6 years old, the most common causes were pneumonia or other lower respiratory tract infection, none had SPM. In 29 cases older than 6 years, 19 of them had SPM. Conclusions Etiologies of pneumomediastinum varied with age in children,which should be vigilantly examined, especially for those younger than 6 years old. The key of the treatment to non-traumatic PM with clear etiologies was to treat its primary disease.

Objective To investigate the effect of three response styles and the ratio scores on Chinese adolescent depressive symptoms,and to investigate the gender differences of response styles and the moderation effects of gender on the relations between response styles and depressive symptoms.Methods The response style questionnaire and the Children's Depression Inventory (CDI) were adopted to measure 932 adolescent twins.Results (1)Rumination was positively associated with adolescent depressive symptoms (r=0.485),positive response styles were negatively associated with adolescent depressive symptoms (r =-0.331).(2) Ratio score was positively associated with adolescent depressive symptoms(r=0.586) and the correlation between ratio score and depressive symptoms was even higher than that between response styles and depressive symptoms.(3) Gender differences of response styles were not significant in Chinese youth samples.(4)Gender moderated the relation between rumination and depressive symptoms(β=-0.07,P＜0.05).Conclusion Ratio scores can explain the relationship between response styles and depressive symptoms better than each of the three individual response styles,and the association between rumination and depressive symptoms is higher in girls.

Objective:To investigate the role of apoptosis-associated speck-like protein(ASC) in non-apoptotic,non-necrotic cell death of neutrophils induced by ONO-AE-248.Methods:The morphological changes of neutrophil nuclei and DNA fragmentation of the cells were examined by confocal microscopy and terminal-deoxynucleotidyl transferase mediated nick end labeling(TUNEL).Neutrophils were stimulated with medium alone,LPS,TNF-? or ONO-AE248 respectively.Then expression of ASC was detected by Western blot.Results:ONO-AE-248-induced neutrophil death was negative in TUNEL assay.Western blot showed that the expression of ASC protein was down-regulated by ONO-AE-248.Conclusion:The DNA degradation of the neutrophils when stimulated by ONO-AE-248 is probably different from that of the typical apoptosis.ASC might be a crosslink point between the ONO-AE-248-induced neutrophil death and spontaneous apoptosis of neutrophils.

Objective To explore the association between the minimum temperature in different seasons and the hospital emergency room visits for cardiocerebrovascular diseases(International Classification of Diseases,tenth vision ICD-10:I00-I99) in Beijing,China.Methods The data of the daily hospital emergency room visits for cardiocerebrovascular diseases(ICD-10:I00-I99)from one of Peking university hospitals,the data of relevant ambient air pollution from the Beijing Municipal Environmental Monitoring Center and the data of meteorological index from China meteorological data sharing service system between 2004— 2006 were collected The time-stratified case-crossover design was used to analyze the data.Results After adjusting SO2,NO2,and PM10,the results showed that each 1 ℃ increase in the daily minimum temperature in summer was associated with the intraday hospital emergency room visits(OR=1.039,P

Objective To explore the association between the daily maximum temperature and hospital emergency visits for cardiovascular and cerebrovascular diseases ( ICD-10: I00～I99) in different seasons in Beijing, China. Methods The data of the daily hospital emergency visits for cardiovascular and cerebrovascular diseases (ICD-10: I00～I99) from a Level-3A hospital in Haidian district in Beijing during 2004-2006 and the corresponding meteorological, air pollution data were collected. The seasonal-stratified case-crossover design and Logistic multiple regression model was used for the data analysis. Results After adjusting the influence of relative humidity, wind speed and atmospheric pressure, for 1℃ increase in daily maximum temperature, the corresponding increase in the hospital emergency visits of the diseases was 17.3%(OR=1.173, 95%CI:1.149～1.197) and 4.2% (OR=1.042, 95%CI: 1.011～1.074) in spring and summer of the years, respectively (P0.05). Conclusion The increase of daily maximum temperature may be a risk factor for daily hospital emergency visits for cardiovascular and cerebrovascular diseases in spring and summer, however, it may be a preventive factor in autumn. The effects of air temperature on health should not be the same in seasons.
