Objective: To evaluate the clinical effcacy of the modiifed anterolateral minimally invasive plate osteosynthesis technique for distal humeral shaft fracture, and to explore its feasibility, security, advantage and disadvantage. Methods: hTe clinical effcacy of 17 patients with distal humeral shatf fracture, who were treated with the anterolateral humerus minimally invasive plate osteosynthesis during 2009 to 2012, were retrospectively analyzed. hTe operative time, bleeding volume, complications, esseous union time and range of motion (ROM) of elbow were recorded, and the functional outcome of elbow joint was evaluated by Mayo elbow performance score (MEPs). The varus angle was measured in the malunion patients atfer the distal humeral shatf fracture healed. Results: All of the 17 patients obtained bony union at an average of 19.2 weeks postoperatively, an average of 4.5 screwes were inserted in distal humerus. hTe mean ROM of elbows was 133° and the MEPS were 98.2. Seven patients suffered humeral malalignment and the mean varus degrees were 8.3°. Conclusion: hTe technique of anterolateral humerus minimally invasive plate osteosynthesis is safe and feasible for distal humeral shatf, and the satisfactory clinical outcomes can be obtained by this modiifed technique. However, some of the patients may appear malunion with varus angulation of humerus.

An old male patient visited the hospital due to shortness of breath and palpitation for 6 h, with fever 3 days before and pump failure at admission. Having no risk factor of coronary diseases such as hypertension, diabetes mellitus and obesity, with ST-T changes and abnormal Q wave on ECC, the signs were compatible with those of acute anterior wall myocardial infarction, while the characteristics of cardiac biomarkers ( significant increase in Troponin I and creatine kinase's isoform, and normal creatine kinase) were not in accordance with those of acute myocardial infarction. Emergency angiography was performed, which indicated normal coronary artery, normal pulmonary artery and global systolic dysfunction of left ventricle. The diagnosis of acute severe myocarditis was established, and intra-aortic balloon pump (IABP) was employed to provide hemodynamic support. Severe myocarditis mimicking acute myocardial infarction may be fatal, and can be easily misdiagnosed. Careful analysis of clinical manifestations, early diagnostic angiography and possible IABP placement are important for the successful treatment.

OBJECTIVETo explore the relationships between quality of life, negative life events, social support and suicide ideation among undergraduates in colleges.

METHODS3517 undergraduates in colleges were recruited by multistage stratified random clustered sampling method. Factors associated with suicide ideation were analyzed with logistic regression by scores of Beck Scale for Suicide Ideation(BSSI), Generic Quality of Life Inventory (GQOLI), Adolescent Self-rate Life Events Checklist (ASLEC), Social Support Rating Scale (SSRS) and a questionnaire on background information.

RESULTSThe rate of suicide ideation within 7 days was 14.1%, especially in females (15.96%), with single parent (23.79%) and disabled undergraduates (25.00%). The primary risk factors for suicide ideation were with low psychological function, material life, family/social support, lower availability of support and more negative life events.

CONCLUSIONThe prevalence of suicide ideation among these undergraduates was high, appropriate measures focusing on these risk factors should be implemented.

OBJECTIVETo investigate the protective effect of six Kaixin San formulas on simulated cells model of depression, Alzheimer's disease and Parkinson's disease.

METHODThe in vitro simulated cells model of depression, Alzheimer's disease and Parkinson's disease was established by injuring SH-SY5Y cells with corticosterone (0.4 mmol x L(-1)) , injuring PC12 cells with neurotoxic amyloid peptide (Abeta25-35) (20 micromol x L(-1)) and injuring SH-SY5Y cells with 1-methyl-4-phenylpyridinium ion (MPP+) (250 micromol x L(-1)). The cell survival rate was assayed with MTT method and the degree of cell injury was detected with LDH.

RESULT100, 500 mg x L(-1) Dingzhixiao Wan prepared as mentioned in Beiji Qianjin Yaofang could significantly increase the survival ratio of SH-SY5Y cells injured by corticosterone and reduce LDH concentration released. All of the Kaixin San formulas could significantly increase the survival ratio of PC12 cells injured by Abeta25-35 and reduce LDH concentration released. Particularly, Kaixin San (10, 100, 500 mg L(-1)) prepared as mentioned in Beiji Qianjin Yaofang shown the best effect. And 500 mg x L(-1) Fushen Wan prepared as mentioned in Gujin Luyan could significantly increase survival ratio of SH-SY5Y cell injured by MPP and reduce LDH concentration released.

CONCLUSIONDingzhixiao Wan prepared as mentioned in Beiji Qianjin Yaofang could protect corticosterone-induced SH-SY5Ycells injury, showing a potential antidepressant effect. All of the six Kaixin San formulas could protect Abeta25-35-induced PC12 cells injury, but Kaixin San prepared as mentioned in Beiji Qianjin Yaofang shown the best potential effect for Alzheimer's disease. Fushen Wan prepared as mentioned in Gujin Luyan could protect MPP(+)-induced SH-SY5Y cells injury to some extent.

BACKGROUNDIt is unclear whether a history of paroxysmal atrial fibrillation (PAF) would impact the effect of catheter ablation on persistent atrial fibrillation (AF). This study aimed to compare the effect of catheter ablation on persistent AF with and without a history of PAF.

METHODSOne hundred and eighty-three patients underwent catheter ablation of persistent AF lasting for > 1 month and were reviewed. Patients were divided into two groups according to whether they had a history of PAF or not. Group I consisted of persistent AF patients with a history of PAF, and group II consisted of persistent AF patients without such a history. All patients received catheter ablation focused on pulmonary vein isolation and were observed for arrhythmia recurrences, which were defined as documented episodes of AF or atrial tachycardia after a blanking period of 3 months.

RESULTSOne hundred and three patients (60.9%) in group I and sixty-six patients (39.1%) in group II were successfully followed and included in analysis. There were no significant differences in clinical and echocardiographic characteristics between both groups except for a younger age and more male patients in group II. After (15.5 ± 10.7) months of follow-up, 59 (57.3%) patients in group I and 49 (74.2%) patients in group II maintained sinus rhythm free of anti-arrhythmia drugs (P = 0.025). Multivariate analyses found left atrial anteroposterior diameter (P = 0.006) and persistent AF with a history of PAF (OR 1.792, 95%CI 1.019 - 3.152; P = 0.043) as the only independent statistical predictors of arrhythmia recurrences.

CONCLUSIONThe arrhythmia recurrence rate of catheter ablation based on pulmonary vein isolation in persistent AF with a history of PAF was higher than those without a history of PAF.

Two Rotavirus G9P[8] strains (LL52696 and LL52727) were recognized during a sentinel-based survey in Lulong, China. Phylogenetic analysis of the VP7 gene showed that both strains isolated constituted a divergent genetic cluster distinct from the other G9 strains isolated in China. Analysis of VP4, VP6, and NSP4 genes revealed that these strains were closely related to Lulong strains. We hold that two strains were reassortant between G9 and Lulong predominant strains.
