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.

Background Phacoemulsification for hard nuclear cataract is easy to cause corneal edema and posterior capsular rupture.Researches determined that soft-shell technique phacoemulsification can effectively reduce corneal edema,but the risk of posterior capsular rupture during the surgery is still existed.Whether intra-capsular bag soft-shell technique can protect the posterior capsular of lens from rupture is still unclear.Objective This study was to observe the effect of intra-capsular bag soft-shell technique phacoemulsification on hard nuclear cataract.Methods A prospective cohort study was designed.One hundred and sixty-eight eyes of 160 patients with age-related cataract and Ⅳ-Ⅴ grade of nucleus were enrolled in Affiliated Second Hospital of Zhengzhou University from November 2013 to May 2015 under the approval of Ethic Commission and informed consent of the patients.The eyes were randomized into the intra-capsular soft-shell technique group and conventional soft-shell technique group with the matched age,gender and nuclear hardness in a manner of randomized block design.A 3.0 mm incision of cataract phacoemulsification with soft-shell technique in capsular bag was performed on 80 eyes of 78 patients in the intracapsular soft-shell technique group,and conventional soft-shell technique phacoemulsification was performed on 88 eyes of 82 patients in the conventional soft-shell technique group.Intraoperative records including the cumulative dissipated energy,effective phacoemulsification time and posterior capsular changes were recorded during the surgery.Postoperative follow-up indexes included corneal edema,endothelial cell density,BCVA and intraocular pressure changes.Results The mean cumulative dissipated energy and operation duration were (20.13 ± 8.34) ％ and (14.28-±2.17) minutes in the intra-capsular soft-shell technique group,and those in the conventional soft-shell technique group were (19.67±5.24)％ and (15.36±3.49) minutes,showing significant differences between them (t =0.216,P =0.376;t =0.403,P-=0.518).Posterior capsular rupture occurred in 1 eye in the intra-capsular softshell technique group and 7 eyes in the conventional soft-shell technique group.The percentages of eyes with BCVA ≥ 0.5 were 78％,83％ and 92％ in postoperative 1 day,1 week and 1 month in the intra-capsular soft-shell technique group,and those in the conventional soft-shell technique group were 56％,71％ and 89％,with a significant increase in postoperative 1 day,1 week in the intra-capsular soft-shell technique group (x2 =5.130,P =0.027;x2 =4.361,P =0.032).The corneal endothelial cell loss rates were 6.97％ and 7.19％ in the intra-capsular soft-shell technique group and conventional soft-shell technique group respectively in postoperative 3 months,with no significant difference between them (P＞0.05).The intraocular pressure was (20.16±4.23) mmHg (1 mmHg =0.133 kPa) in postoperative 1 day in the intra-capsular soft-shell technique group,which was significantly higher than (17.38± 5.21) mmHg in the conventional soft-shell technique group (t =1.241,P =0.037).Conclusions Intra-capsular bag soft-shell technique phacoemulsification for hard nuclear cataract can decrease the intraoperative and postoperative complications and quicken the visual recovery after surgery.

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 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.

Comorbidity, which can affect the treatment and prognosis of its disease, has gradually caught attention from both at home and abroad. Although chronic obstructive pulmonary disease (COPD) mainly involved lung tissues, it may also cause the systemic (or extra-pulmonary) adverse effects. Many types of comorbidities existed in COPD. This article summarized the prevalence, risk factors and pathogenesis of comorbidities such as cardiovascular disease, osteoporosis, anxiety and depression, lung cancer, infection, metabolic syndrome and diabetes mellitus. It also con-ducted related studies on the diagnosis and treatment status and current problems of COPD comorbidities, which may provide evidences for COPD outcome evaluation.

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.
