Objective To observe the effectiveness of botulinum toxin A (BTXA) in the treatment of small sample patients with acute acquired concomitant esotropia. Design Retrospective case series. Participants 6 patients (3 female and 3 male) with acute acquired concomitant esotropia aged 6 to 34 years. Methods All the patients were received 2.5 units of BTXA injected into the bilateral medial rectus muscles once under electromyographic control. They were performed alter prism-cover test,synoptophore and stereoscopic charts test. Main Outcome Measures The alignment of eyes and binocular vision. Results The follow-up of patients was 4 to 39 months. The pre-injection angle of deviation was 43.3?1.0△; the angle of deviation at the last follow-up was 3.3?8.2△,and 5 patients achieved alignment. In pre-injection,one patient had distance stereopsis,2 patients had near stereopsis with 600 seconds and 40 seconds; after injection,5 patients demonstrated distance and near stereeopsis (3 patients 40 seconds,1 patient 60 seconds,and 1 patient 200 seconds). Conclusion This small sample study shows that BTXA injection is effective alternative in treating acute acquired concomitant esotropia.

Towards the problems after the medical reform of China,such as dramatic increase of healthcare expenditure and conflict between doctor and patient,this paper analyzes the tripartite relationships between hospital,insurance supplier and patient from the theoretical and practical aspects,concludes that the non-balanced development of the current relationships is an important reason of the problems,and gives the corresponding countermeasures for reference.

Objective To investigate the protective effects of recombinant human erythropoietin(rhEPO)treatment on histopathologic changes seen in hyperoxia induced lung injury.Methods Rat pups were randomly divided into four groups:Ⅰ:air-exposed control group,Ⅱ: air-exposed+rhEPO-treated group,Ⅲ:hyperoxia-exposed control group,Ⅳ:hyperoxia-exposed+rhEPO-treated group.GroupⅢ and Ⅳ rats were exposed to 85% oxygen.GroupⅡand Ⅳ rats were received rhEPO (1 200 U/kg) subcutaneously on postnatal 0 day and 2 day.On postnatal 14 day,survival curve,measurement of body weight and lung weight,radical alveolar counts(RAC),microvessel count were compared,CD_ 31 and vascular endothelial growth factor(VEGF) were performed by immunostaining to assess hyperoxia-induced changes in lung morphology.Results Treatment of hyperoxia-exposed rats with rhEPO prolonged the survival and resulted in a significant increase in the weight gain of body and lung[(25.88?2.59) vs(18.8?3.93) P

According to the requirements of the ‘three guidance’ talent-cultivation model pro-posed by our university, humanistic spirit was permeated from multi angels during the process of phys-iology. Students'occupation quality was cultivated; physiology knowledge and clinical practice was combined for students; early contacting with clinical knowledge was conducted and teacher-student role reversal method was applied to train students' communication skills. Teaching practice showed that the reformed teaching model not only can ensure the quality of teaching but also can improve the comprehensive quality of students.

Objective To compare the perioperative safety and curative effects oflaparoscopic adrenal sparing surgery (ASS) with laparoscopic total adrenalectomy (TA) for aldosterone producing adenoma (APA).Methods An online systematical retrieval was performed with Pubmed,ScienceDirect,Springerlink,the Cochrane library,CNKI and China Biology Medicine disc for clinical comparative studies published before May 2016,these studies reported the treatment of ASS/partial adrenalectomy (PA) versus TA for APA.The selected studies were applied to Revman 5.3 software for meta-analysis.The main contents were perioperative outcomes (operative time,intra-operative blood loss,and length of hospital stay) and postoperative efficacy (cure rate,partial response rate,inefficiency rate).Results A total of 9 clinical studies (3 English documents and 6 Chinese documents) with 1036 patients were included into the final analysis,among which 544 patients were assigned to ASS group and 492 in TA group.The analyzed results demonstrated no statistical significance between ASS group and TA group on operative time (WMD:-2.09min,95％CI:-9.86-5.67,P=0.60),length of hospital stay (WMD:-0.10d,95％CI:-0.32-0.12,P=0.36),intra-operative blood loss (WMD:1.13ml,95％CI:-8.86-11.12,P=0.82),cure rate (OR=l.07,95％CI:0.73-1.58,P=0.72),partial response rate (OR=0.85,95％CI:0.57-1.27,P=0.43) and inefficiency rate (OR=2.15,95％CI:0.32-14.34,P=0.43).Conclusion For surgical treatment of APA,ASS is technically safe,can achieve reliable postoperative efficacy and a similar therapeutic effect compared with TA,so deserves further application in clinical practice.

Observed index is a very important element in a research design, because it is a specific reflection of the effects of research factors on the research subjects and is indispensable in any research. Generally, there are two types of observed indexes: the indexes that reflect natural attributes, habits or states of the research subjects and the indexes that reflect the effects of different drugs or treatments on research subjects. This article mainly introduces the definition, characteristics, selection and observation of research indexes and the major and minor indexes.
