Objective To observe the levels of plasma and urinary urotensin Ⅱ in patients with Type 2 diabetes mellitus (DM)and to investigate the influence of renal impairment and other involved clinical or laboratory feature on them. Methods The 42 patients with type2 patients were divided into three groups according to their correctional clearance of creatinine(Ccr):Group A(n=14)with Ccr≥70 mL/min; group B(n=18)with 30≤Ccr

Soft environment of opening laboratory in key subject will deeply affect the construction and development of disciplines.Developing and innovative academic team;scientific and rigorous running mechanism,healthy and concordant academic atmosphere,active and positive behavior mode,all of the above are the main factors of soft environment of laboratory.From now on,we need try our best to improve human rights,design more efficient aims,constitute impellingly guarantee system and fine mechanism of consistent of regulations and environment,apply modern managing instrument scientificly and improve managing efficiency.

Objective To explore the influence of lack of parental accompaniment, physical abuse and neglect in childhood on the psychological distress of college entrant students. Methods In a comprehensive university in Sichuan Province, 8367 freshmen were surveyed using the 6-item Kessler psychological distress (K6) scale and a questionnaire for lack of parental accompany, physical abuse and neglect in childhood. The students were divided into rural group and urban group for data analysis. Results The months of lack of maternal and/or paternal accompaniment were more in rural group than that in urban group (P<0.05). In rural group, female (standardizedβ’=0.139, P<0.001), neglect (standardizedβ’=0.237, P<0.001) and physical abuse (standardized β’=0.076, P<0.001) were associated with K6 scale. In urban group, female (standardizedβ’=0.091, P<0.001), lack of paternal accompaniment (standardizedβ’=0.050, P<0.001), ne? glect (standardized β’=0.169, P<0.001) and physical abuse (standardized β’=0.095, P<0.001) related with K6 scale. Conclusions Neglect and physical abuse are independent risk factors to freshmen both from rural and urban areas. Lack of paternal accompaniment in childhood is a risk factor only in urban freshmen. Further research should select more rep?resentative samples and also include more factors which may interact with the loss of parental accompaniment such as pa?rental divorce and conditions regarding so calledleft-behindchildren in rural area.

Objective    To summarize the clinical experience in the treatment of high-risk patients with severe aortic valve disease by transcatheter aortic valve implantation (TAVI) via heart apex approach and to evaluate the early efficacy. Method    Five patients who underwent TAVI via heart apex approach from September 2017 to February 2019 in Henan Thoracic Hospital were retrospectively analyzed, including 3 males and 2 females, aged 65-84 (74.6±4.5) years. Result    All operations were performed through a small left incision into the thoracic cavity (3-5 cm), and then through the J-Valve transport system, the aortic valve was successfully released via heart apex after precise positioning under digital subtraction angiography. One patient developed ventricular fibrillation during the operation, and the operation was completed with the assistance of emergency femoral arteriovenous catheterization cardiopulmonary bypass; one patient underwent percutaneous coronary intervention first because of severe coronary stenosis; one patient had paroxysmal atrial fibrillation during the perioperative period, and had hepatorenal insufficiency and thrombocytopenia after the operation, and was improved after medical treatment; one patient had perivalvular leak during the operation, and was improved after re-implantation of the valve; one patient was in stable condition during operation and recovered smoothly after operation. Surgery was successful in all 5 patients. The follow-up time was 2-19 months, and the early clinical effect was good. Conclusion    The short-term clinical efficacy of TAVI via heart apex approach in the treatment of high-risk severe aortic valve disease is definite and safe, but the long-term and medium-term effects need to be further evaluated.
