Gene×environment interaction in major depressive disorder

Major depressive disorder(MDD)is a multifactorial disorder,where multiple susceptibility genes interact with environmental factors,predisposing individuals to the development of the illness.In this article,we reviewed different gene×environment interaction(G×E)studies shifting from a candidate gene to a genome-wide approach.Among environmental factors,childhood adversities and stressful life events have been suggested to exert crucial impacts on MDD.Importantly,the diathesis-stress conceptualization of G×E has been challenged by the differential susceptibility theory.Finally,we summarized several limitations of G×E studies and suggested how future G×E studies might reveal complex interactions between genes and environments in MDD.

Effect of danhong injection combined with nadroparin calcium on serum CyS-C, CRP, IL-6, vWF, ET and VEGF in patients with acute coronary syndrome

Objective: To study the effect of danhong injection combined with nadroparin calcium on serum CyS-C, CRP, IL-6, vWF, ET and VEGF in patients with acute coronary syndrome. Methods: A total of 80 patients with acute coronary syndrome in our hospital from July 2014 to July 2017 were enrolled in this study. The subjects were divided into the control group (n=40) and the treatment group (n=40) randomly. The control group was treated with xuesaitong injection combined with nadroparin calcium;the treatment group was treated with danhong injection combined with nadroparin calcium. The two groups were treated for 2 weeks. The serum CyS-C, CRP, IL-6, vWF, ET and VEGF levels of the two groups before and after treatment were compared. Results: There were no significantly differences of the serum CyS-C, CRP, IL-6, vWF, ET and VEGF levels of the two groups before treatment. The serum CyS-C, CRP, IL-6, vWF, ET and VEGF levels of the two groups after treatment were significantly lower than before treatment, and that of the treatment group were significantly better than that of the control group. Conclusion: Danhong injection combined with nadroparin calcium can significantly reduce the serum CyS-C, CRP, IL-6, vWF, ET and VEGF levels of patients with acute coronary syndrome, and it was worthy clinical application.

One-stop strategy for treatment of atrial fibrillation:feasibility and safety of combining catheter ablation and left atrial appendage closure in a single procedure

Background:Catheter ablation is effective in restoring sinus rhythm and left atrial appendage closure(LAAC)is increasingly used for stroke prevention in patients with atrial fibrillation(AF).We aimed to observe the feasibility and safety of performing AF ablation and LAAC in a single(one-stop)procedure.Methods:Consecutive AF patients who underwent the combined procedure of AF ablation and LAAC with WATCHMAN device between March 2017 and September 2018 were prospectively enrolled.Baseline and intra-procedural parameters were evaluated.Three-month and subsequent 1-year follow-up were performed in all and earlier-enrolled subjects,respectively.Results:A total of 178 AF patients(94 males,68.9±8.1 years)underwent the one-stop procedure with CHA2DS2-VASc score 3.3±1.5 and HAS-BLED score 1.6±1.0,respectively.Pulmonary vein isolation was achieved in all patients while additional linear ablation was applied if the operator deemed necessary,yielding immediate ablation success rate of 98.9%(176/178).In the subsequent LAAC,satisfactory seal(residual leak<5 mm)was achieved in all patients.One stroke and four cardiac perforations occurred peri-operatively.At 3-month follow-up,sinus rhythm and satisfactory seal were maintained in 153/178(86.0%)and 178/178(100%)patients,respectively.One stroke and one delayed cardiac tamponade occurred,while no device-related thrombus or device migration was observed.During the 1-year follow-up for the earlier enrolled subjects,52/72(72.2%)of the patients maintained sinus rhythm.There was no stroke or systemic embolism observed.Conclusion:Combining catheter ablation and LAAC in a single procedure can be successfully and safely performed in non-valvular AF patients of Chinese population.
