Objective To investigate the effects of adiponectin on cell activity and expression of T-cadherin in human retinal pigment epithelial(hRPE) cells cultured with high glucose.Methods ①The hRPE cells were divided into three groups:normal glucose group(5.5mmol/L glucose),high glucose group (33mmol/L glucose),high glucose plus adiponectin group (33mmol/L glucose+2.5ug/ml adiponectin).48h later,the cell activity was observed by MTT assay.②After the above groups were cultured respectively for 24h,48h,72h again,the expression of T-cadherin mRNA was observed by RT-PCR. Results ①Cell activity in high glucose group significantly decreased. Cell activity adiponectin group was higher than that in the high glucose group.②With the extension of time ,the expression of T-cadherin decreased in high glucose group,but increased in adiponectin group. Conclusion Adiponectin may be protect the hRPE cells by T-cadherin.

Objective To study the chemical constituents in the stem of Acanthus ilicifolius.Methods Some compounds were repeatedly isolated and purified on silica gel column chromatography and vacuum liquid chromatography,their chemical structures were elucidated by their physicochemical properties and spectral data,such as IR,(()~1HNMR),(()~(13)C-NMR),and ESI-MS.Results Eight compounds were obtained from the stem of A.ilicifolius and identified as hexacosanoic acid(Ⅰ),stigmasterol(Ⅱ),tetratriacontanol(Ⅲ), 2-benzoxazolinone(Ⅳ),stigmasterol-3-O-?-D-glucopyranoiside(Ⅴ),vanillic acid(Ⅵ),4-hydroxy-2-benzoxazolone(Ⅶ),quercetin(Ⅷ).Conclusion Compound Ⅶ is first reported as a natural product.Compounds Ⅰ,Ⅲ,and Ⅵ-Ⅶ are reported from this plant for the first time.

Objective to investigate the situation of occupational health of nurses,so as to provide a reference for protecting the health of nurses. Methods Cluster sampling method was employed in this study. totally 1 204 nurses of two three-level general hospital and a cancer hospital in Bei-jing were randomly surveyed with homemade health of nurses′cross-sectional questionnaire,and a nurse medical examination report was access at the same time. Results there was statistically significant difference in the incidence of nurses work pressure and work fatigue in different hospitals and different departments(P < 0.05). 95.18% of the nurses undergo regular medical examinations,of which 56.97% were found abnormal. the dif-ferences in the incidence rate of abnormal medical examination results in nurses were statistically significant among different hospital and different de-partments(P < 0.05). Conclusion Great job stress and work fatigue are observed in nurses,and they have health problems. It is necessary for the hospital to take appropriate interventions to improve physical and mental health nurses.

Objective To evaluate the safety and effect of extraperitoneal laparoscopic radical prostatectomy for high-risk prostate cancer. Methods From January 2012 to August 2015, 49 patients diagnosed high-risk prostate cancer underwent extraperitoneal laparoscopic radical prostatectomy with 'sandwich' urethra reconstruction. Results None converted to open surgery and the mean operative time was (2.15 ±0.29) h, mean intraoperative blood loss was (60.25 ± 20.29) ml. No rectal injury was observed. The patients were ambulant 1 to 2 days postoperatively. Pelvic lymph nodes metastasis was found in 5 cases. Positive margin was found in 13 cases. Mild urinary incontinence oc-curred in 3 cases. Urethral stenosis occurred in 2 cases. Biochemical relapses occurred on 5 cases during the follow-ing period of 1~43 months for 46 cases. Conclusions Extraperitoneal laparoscopic radical prostatectomy is safe and effective in treatment of high-risk prostate cancer. The very key is to master the anatomy of prostate and laparoscop-ic techniques.

With the development of neuroimaging techniques and the extensive application in clinical practice,the case reports about migrainous cerebral infarction have increased progres- sively,and have received extensive attention.However,its exact pathogenesis still remains unclear.In recent years,with the application of functional neuroimaging techniques,people have a new insight into the pathophysiological mechanisms of migrainous cerebral infarction,This article reviews the advanced in research on the pathogenesis of migrainous cerebral infarction.

Objective:To investigate the relationship between psychological factors and the serum level of estrogen in menopausal women with glossdynia.Methods:87 menopausal women with glossdynia and a randomly selected control group (n=82) were comprehensively investigated with the method of case-control study.The serum level of estradiol(E2) and follicle stimulating hormone(FSH) were measured.All cases with glossdynia and control were evaluated by the Self-Rating Annxiety Scale(SAS) and Self-Rating Depression Scale(SDS). Results: The serum level of E2 was significantly lower in menopausal women with glossdynia than that in control group( P

Objective To systematically assess the relationship between oral administration of aspirin and survival benefit for patients with colorec?tal cancer(CRC)by meta?analysis. Methods Relevant studies were identified through searching PubMed and EMBASE. Random?effects model was derived to composite the pooled hazard ratio for overall mortality and CRC?specific mortality. The subgroup analysis was conducted for included data,and the bias analysis was reported. Results Thirteen studies on aspirin therapy were finally included in this meta?analysis. The overall surviv?al benefit associated with oral administration of aspirin represented an HR of 0.83(95%CI:0.71?0.96). Oral administration of aspirin was also asso?ciated with CRC?specific survival(HR=0.77,95%CI:0.64?0.93). No evidence was observed of an association between prediagnostic aspirin use and CRC overall survival(HR=1.00,95%CI:0.85?1.18)or CRC?specific survival(HR=0.97,95%CI:0.83?1.13). Conclusion These findings provide further indication that post?diagnostic aspirin therapy can improve CRC prognosis.

Retinitis pigmentosa (RP) is a large group of common hereditary eye diseases with highlyheterogeneous genetic background. Over forty genes with diverse functionalities are associated with RP and they include a set of ubiquitously expressed genes. These include five genes involved in the precursor messenger RNA( premRNA) splicing. Recent progress in disease gene identification for RP has established the involvement of pre-mRNA splicing as one important mechanism in the disease etiology and has shed light on the splicing process itself, a fundamental biological process. To this date, studies in this field have been focused on two major issues. First, how do the mutations of the adRP associated splicing factors (adRP-SF) affect the splicing function? Second, how do the mutations in these ubiquitously expressed genes lead to specific retinopathy? The two topics fit with the two continuous important steps of the disease pathogenesis. Recently, researchers have made a dramatic progress in the first topic. The identification of the SNRNP200 gene,the fifth adRP-SF and its relevant functional study has shown significance to the progress in the study of RP. Numerous investigations are also being carried out in addressing the second issue.Generation of a variety of models led to a better description of the pathological process of the disease. However, in respect to the key pathogenic mechanism,researchers are still puzzled with a number of confusing questions. In this commentary,the results from the latest investigations were summarized, and in particular,the difficulties in studying the molecular mechanism by which the pre-mRNA splicing deficiency causes RP were detailed.

Objective　To study chemotherapy sensitivity and apoptosis in tumor cell line.Methods　Two different human colon carcinoma cell lines, LoVo and Ls-174-t were incubated with DDP,MMC,5-FU，EPI at various peak plasma concentrations (PPC), 1/10PPC，1/5PPC，5PPC and 10 PPC. Apoptosis was detected by FACScan and TUNEL technique after 24 hours and 48 hous. Cell growth inhibition rates were assessed by MTT, DNA ladder were examined by agarose electrophoresis.Results　At 48 hours, the highest cellular apoptosis rates were observed with PPC which was assessed by FACScan technique. There was a positive linear correlation between apoptosis assessed by TUNEL technique and growth inhibition rates of cells determined by MMT(P＜0.05).Conclusion　Using Annexin-V-Fluos staining FACScan technique to assess apoptosis of tumor cells is an exploring and useful method which can be used to choose both kinds and doses of chemotherapeutic drugs.
