1.PDIA3:a new therapeutic target of diseases
Chinese Journal of Pathophysiology 2015;(6):1145-1149
Protein disulfide isomerase A3 (PDIA3) is a member of protein disulphide isomerase family and widely exists in endoplasmic reticulum, cell surface, nucleus and mitochondria.PDIA3 promotes the glycoprotein folding and quality control in the endoplasmic reticulum and is also a key molecular of major histocompatibility complex class I mol-ecules assembly.In addition, PDIA3 is involved in the cell signal transduction and plays an important role in a variety of disease development.Therefore, this paper talks about the function of PDIA3, the relationship between disease and PDIA3 as well as its clinical outlook.
2.Advances in endostatin research
Chinese Journal of Pathophysiology 2000;0(07):-
Endostatin, a 20 kD (184 aa) C-teminal fragment of collagenⅩⅧ,is the most potent inhibitor of tumor angiogenesis described so for. Endostatin was initially isolated from a murine hemangioendothelioma cell line (EOMA). Purified recombinant murine endostatin generated in E.coli bacteria injected as unfolded suspension, inhibited the growth of a varity of metastatic and primary tumors in mice. However, its widespread application has been hampered by difficulties in the large-scale production of the antiangiogenic proteins. The limitation may be resolved by in vivo delivery and expression of the antitangiogenic gene. This review summarized the advances in endostain research in recent years including structure, the mechanism of generating ,function and therapy.

Objective To evaluate the efficacy of probiotics to treat irritable bowel syndrome (IBS).Methods Publications from database including PubMed,the Cochrane Library,Embase,CNKI,CBM and WanFang Data were searched up to August 31,2014.The randomized controlled trials (RCTs) on probiotics to treat IBS were eligible.The related articles were extracted and cross-checked independently by two reviewers.Methodological quality of trials was evaluated according to Cochrane Handbook 5.1.0 criteria.Meta-analysis was conducted using RevMan 5.2 software.Results A total of 17 RCTs involving 1 700 patients were included.Results of meta-analyses showed that compared with the placebo,probiotics was statistically better in improving the overall symptoms integral (SMD =-0.20,95% CI-0.33--0.07,P =0.002),alleviating abdominal pain/discomfort (SMD =-0.19,95% CI-0.29--0.09,P < 0.001),relieving abdominal distention (SMD =-0.16,95% CI-0.28--0.03,P =0.020),and defecation discomfort (SMD =-0.22,95% CI-0.42--0.02,P =0.030).There was no statistical significance in the overall quality of life (SMD =-0.08,95% CI-0.07-0.23,P =0.290) and adverse effect ratio (RR =1.08,95%CI0.79-1.49,P=0.630).Conclusion Probiotics have beneficial effects on IBS,which can improve the patients' symptoms and with less adverse reaction.Due to the bias,further large-scale,multicenter and high-quality RCTs are required to unify outcome indicators,further define sensitive strain,and standardize its usage,dosage and course of treatment.
5.Clinical value of nerve stimulator-versus ultrasound-guided continuous femoral nerve block for analgesia after laparoscopic surgery
Chinese Journal of Anesthesiology 2014;34(10):1204-1206
Objective To compare the clinical value of nerve stimulator-versus ultrasound-guided continuous femoral nerve block for analgesia after laparoscopic surgery.Methods Forty patients,aged 18-60 yr,with body mass index of 18-30 kg/m2,of ASA physical status Ⅰ or Ⅱ,scheduled for elective laparoscopic surgery,were randomly assigned into 2 groups (n =20 each) using a random number table:nerve stimulator group (group S) and ultrasound group (group U).Epidural anesthesia was performed with 1.73 % carbonated lidocaine in both groups.0.2% ropivacaine 5 ml/h was infused continuously after surgery to perform femoral nerve block for analgesia.VAS score at rest was assessed at 2,6,24 and 48 h after surgery.At 24 and 48 h after surgery,VAS scores during active and passive movement were assessed.The time for catheter placement near the femoral nerve and development of subcutaneous hematoma at the puncture site,local anesthetic intoxication and nausea and vomiting were recorded.The postoperative requirement for analgesics was also recorded.Results There was no significant difference in the VAS scores and puncture for femoral nerve block-and local anesthetics-related adverse events between the two groups.The time for catheter placement near the femoral nerve was 8.0 ± 1.4 and (6.7 ± 0.9) min in S and U groups,respectively,and the time was significantly longer in group S than in group U.No patients required rescue analgesic after surgery in both groups.Conclusion Nerve stimulator-guided continuous femoral nerve block provides higher clinical value than ultrasound-guided continuous femoral nerve block for analgesia after laparoscopic surgery and it is more suitable for clinical application.
7.Discussion of food safety law from the viewpoint of food sanitation law enforcement
Chinese Journal of Medical Education Research 2006;0(09):-
Food Sanitation Law which was issued for many years has no longer been congruent with the current development of socio-economy. Under this situation,Food Safety Law came into being. Although the promulgation of the law is important,the task of carrying out the law is more difficult. On the basis of concluding the problems in carrying out the food sanitation law and the analysis of its causes,it is significant to discuss the Food Safety Law from the viewpoint of Food Sanitation Law enforcement.
8.Fibrin glue combined with vascular endothelial growth factor and recombinant human bone morphogenetic protein 2 applied in spinal fusion
Chinese Journal of Tissue Engineering Research 2016;20(25):3699-3705
BACKGROUND: Bone morphogenetic protein 2 possesses osteoinduction, and vascular endothelial growth factor plays a positive regulatory role in osteogenesis and bone repair. So what wil happen if both of them are used for spinal fusion? OBJECTIVE: To investigate the effects of fibrin glue combined with vascular endothelial growth factor 165 and recombinant human bone morphogenetic protein 2 on intertransverse process fusion. METHODS: Thirty Japanese white rabbits were randomized into three groups (n=10 per group): rabbits underwent intertransverse process fusion at the level of L5-6 with vascular endothelial growth factor 165/recombinant human bone morphogenetic protein 2/fibrin glue in experimental group, recombinant human bone morphogenetic protein 2/fibrin glue in control group, and fibrin glue in blank control group, respectively. At 6 weeks after implantation, observations of biomechanics, X-ray imaging and histology were performed. RESULTS AND CONCLUSION: Osteogenic fusion between transverse processes could be found in experimental and control groups except for the blank control group, which was better in the experimental group. The strength of osteogenic fusion in the experimental group was significantly stronger than that in the control group (P < 0.01). Besides, abundant chondrocytes, osteocytes, mature bone tissues and col agens could be found in the osteogenic fusion specimen of the experimental group, and numerous chondrocytes, osteocytes and mature bone tissues observed in the osteogenic fusion specimen of the control group. In conclusion, fibrin glue combined with vascular endothelial growth factor 165 and recombinant human bone morphogenetic protein 2 can promote osteogenic fusion.

Objective To know the hygienic condition of different kinds of drinking water plants in Shanxi Province.Methods In 2007,422 water plants and 2 083 secondary water supply units were selected and the information and data that provided by all Sanitation Institute for Health Inspection and Supervision in Shanxi Province were analyzed.Results The hygienic conditions of city's municipal administration water supply systems were the best.Total qualified rate of water quality was 97.67%.The hygienic conditions of rural school's homemade water supply systems were the worst,the qualified rates of all items in the program were the lowest.Most of them had no any analyst and laboratory for water quality test.Only 10.2% of them had water disinfection facilities.Total qualified rate of water quality was 75.32%.In most of water plants,the lack of water quality test facilities and disinfection facilities was one important problem in drinking water safety.In addition,the lack of clean and disinfection in secondary water supply systems was another problem.Conclusion The hygienic conditions of drinking water plans are unsatisfactory and should be improved in Shanxi Province.
