To realize long-term long distance space exploring flight,the bioregenerative life support system has to be applied.Producing animal protein in this system could increase its closure ability and stability.In this paper,researches and developments on the animal protein production in the bioregenerative life support system from various countries including our research results were introduced in detail through information analyses.The prospects in the future studies were also predicted.It has important references for our country to carry out related investigations.

Posterior capsular opacification (PCO) is one of the major complications of modern cataract surgery.Multiple studies had demonstrated that the extracellular matrix (ECM) plays an important role in the generation and development of PCO.A variety of ECM components,including fibronectin (FN),laminin (LN),collagen,lumican,osteoponin (OPN),decorin,hyaluronic acid and vimentin,affect the biological properties of lens epithelial cells (LECs) through different mechanisms,such as regulating cell migration,adhesion and proliferation.This review focuses on the role of ECM in PCO formation in order to explore the pathogenesis of PCO and provide a potential therapeutic approach for the prevention and management of PCO.

OBJECTIVE: To provide references for adapting to the new medical reform and facilitating development of hospital pharmacy. METHODS: By studying and analyzing the new "medical reform" program, comparing the development of hospital pharmacy at home and abroad, hospital pharmacy development direction and pharmacist working mode in China are put forward. RESULTS: The function of hospital pharmaceutical care lags behind the development of new "medical reform", which thus calls for further improvement. CONCLUSION: Under the new condition of medical reform, it is imperative to perfect the related system and implement pharmacist service fee as soon as possible, to facilitate rapid development of pharmacist team and guarantee the system of essential drugs with rational drug use as focus smooth implementation.

Objective To investigate the change of E-cadherin expression in human skin after cryopreservation. Methods The skin tissue was treated with DMSO-propyleneglycol (TD group) and trehalose-DMSO (DP group), respectively, and cryopreserved in liquid nitrogen (-196 ℃) for 7 and 14 days and the changes after cryopreservation were compared with that of fresh skin (control group). Immunohistochemical staining was used to detect the expression of E-cadherin in the skin.Results Compared with the fresh skin, TD group showed good preservation of the skin, and the expression level of E-cadherin was similar to that in the control group. Conclusion E-cadherin is well preserved in the TD group. Therefore, trehalose-DMSO is an effective cryoprotectant for human skin, and much better than that of traditional low-temperature protectants.

Objective To explore the relationship between the Chinese Version Wechsler intelligence scale for children(C-WISC) and the Das-Naglieri cognitive assessment system(DN:CAS) in children with attention deficit hyperactivity disorder (ADHD).Methods Thirty-two children with ADHD were evaluated with C-WISC and the digital remote assessment system——DN:CAS,and both results were administered for correlation analysis.Results The results showed that there was a strong correlation between the full intelligence quotient (FIQ) of C-WISC and the full score of DN:CAS,also the scores in Plan,Simultaneous,and Successive of DN-CAS,and the correlation coefficient was between 0.6 to 0.8.There was a strong correlation between the full score of DN:CAS and the verbal comprehension IQ (VCIQ),perceptual organization IQ (POIQ),memory/concentration IQ (M/CIQ),verbal IQ (VIQ),and performance IQ(PIQ) of C-WISC,as the correlation coefficient ranges from 0.6 to 0.8.There was also a strong correlation between the score in Planning and VCIQ,POIQ,M/CIQ,VIQ of C-WISC.As to the score in Simultaneous of DN:CAS and POIQ,VIQ,PIQ of C-WISC,the correlation was also strong with the correlation coefficient ranging from 0.6 to 0.8.For the rest of the sub-tests of C-WISC and DN:CAS,there was moderate correlation between them,the correlation coefficient was from 0.4 to 0.6.Conclusions These results show that the correlation between C-WISC and DN:CAS in children with ADHD is significant.The correlation coefficient shows diversity in the sub-tests of C-WISC and DN:CAS.

Objective To explore the effect of perioperative continuous use of aspirin on bleeding in laparoscopic anterior resection for rectal cancer (RC) in patients taking low dose aspirin.Methods The prospective study was conducted.The clinicopathological data of 96 RC patients taking low dose aspirin who were admitted to the Shengjing Hospital of China Medical University from September 2014 to September 2016 were collected.All the 96 patients were divided into the aspirin group (perioperative continuous use of aspirin) and non-aspirin group (discontinuation of aspirin at 7 days preoperatively and taking aspirin at 3 days postoperatively)by random number table.Laparoscopic anterior resection for RC was applied to patients by the same team of doctors.Observation indicators:(1) comparison of surgical and postoperative situations between the 2 groups;(2) follow-up situations.Follow-up using outpatient examination and telephone interview was performed to detect the postoperative survival of patients up to January 2017.Measurement data with normal distribution were represented as (x)±s.Comparisons between groups were evaluated with the t test.Comparisons of count data were analyzed using the chi-square test and Fisher exact probability.Comparison of ordinal data was analyzed using the nonparametric test.Results All the 96 patients were enrolled into the study,including 50 in the aspirin group and 46 in the non-aspirin group.(1) Comparison of surgical and postoperative situations between the 2 groups:96patients underwent successful laparoscopic anterior resection for RC,including 1 with conversion to open surgery and 95 undergoing laparoscopic anterior resection for RC,without perioperative death,postoperative blood transfusion and rcoperation.Cases with conversion to open surgery,operation time,volume of intraoperative blood loss,decreasing value of postoperative hemoglobin (Hb),time to anal exsufflation,peritoneal drainage volume from 1-3 days postoperatively,cases with postoperative hematoehezia,cardio-cerebrovascular complications and overall complications (including postoperative hematochezia and cardio-cerebrovascular complications),duration of hospital stay,hospital expenses,cases in stage Ⅰ,Ⅱ and Ⅲ of postoperative TNM stage,postoperative coagulation indexes of platelet,prothrombin time,international normalized ratio,prothrombin activity,activated partial thromboplastin time,thrombin time and fibrinogen were 0,(112± 18) minutes,(39± 18) mL,(4.3±2.8)g/L,(57±24)hours,(22±9)mL/d,6,0,10,(8.6±2.5)days,(6 739±481)yuan,11,35,4,(236±80) × 109/L,(12.7± 1.1) seconds,1.00±0.08,101％ ± 15％,(28 ±4) seconds,(15.5 ± 1.9) seconds,(3.2±1.0)g/L in the aspirin group and 1,(118±16)minutes,(38±22)mL,(3.5±3.0)g/L,(55±29)hours,(20±8)mL/d,4,1,8,(9.1±2.3)days,(6606±510)yuan,5,36,5,(211±49)×109/L,(12.5±0.7)seconds,1.00±0.06,103％±11％,(29±3)seconds,(15.3±1.7)seconds,(3.1±0.7)g/L in the non-aspirin group,respectively,with no statistically significant difference between the 2 groups (t =-1.737,0.204,1.416,0.380,1.365,x2=0.038,0.107,t=-1.082,1.322,Z=-1.370,t=1.850,0.978,0.872,-0.712,-1.291,0.311,0.585,P＞0.05).Ten patients with postoperative hematochezia in the 2 groups were cured,without special treatment.One patient in the non-aspirin group was complicated with deep venous thrombosis and then was cured by single anticoagulant drug.Two and 2 patients in the aspirin group were respectively complicated with urinary retention and urinary tract infection.One,1 and 1 patients in the non-aspirin group were respectively complicated with inflammatory intestinal obstruction,urinary retention and urinary tract infection,and then were cured by conservative treatment.(2) Follow-up situations:of 96 patients,95 were followed-up for 4-27 months,with a median time of 13 months.During the follow-up,3 patients died and 92 had survival.Conclusion The perioperative continuous use of aspirin cannot increase risk of bleeding in laparoscopic anterior resection for RC in patients taking low dose aspirin.
