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.

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 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 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.

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 observe the effect of laser of Q Switch Nd:YAG 1 064nm wave length laser in the treatment of naevus fusco caerulens zygomaticus. Methods Since October 2000, forty nine cases of naevus fusco caerulens zygomaticus had been treated once every three months. Results Thirty two cases had been treated three times, and seventeen cases, four times. The total effective rate was 100 %. The pigmentation of all the cases were darker after the first treatment, later as the treatment progressed, the pigment became lighter. No pigment loss was seen. Conclusion Q switch Nd:YAG 1 064 nm wavelength laser has a good effect in the treatment of naevus fusco caerulens zygomaticus. It is safe and reliable.

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 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.

Objective To evaluate the efficacy and safety of using basiliximab in place of a corticosteroid for immunosuppression following liver transplantation for hepatocellular carcinoma (HCC) in Chinese patients.Method The records of 178 patients with HCC who underwent orthotopic liver transplantation from January 2003 to December 2009 were retrospectively reviewed.All patients received immunosuppression therapy that contained either basiliximab (n =78) or steroids (n =100) in addition to tacrolimus and mycophenolate mofetil.Assessments included complications related to liver transplantation,occurrence of steroid side effects,recurrence of HCC,and patient and graft survival.Results A smaller proportion of patients receiving basiliximab than steroids experienced de novo diabetes (38.7％ vs.91.0％,respectively) or long-term de novo diabetes mellitus (4.0％ vs.30.3％,respectively) (both,P＜0.0001).The median overall and disease free survival was similar between basiliximab (50.8 months and 19.6 months,respectively) and steroid treated patients (64.2 months and 23.8 months,respectively).The 5-year overall survival and disease free survival rate was also similar between the basiliximab (42.5％ and 38.9％,respectively) and steroid (50.5％ and 39.2％) groups (all,P＞0.730).However,in patients who met the Milan criteria basiliximab was associated with greater 5 year overall survival rate than steroid therapy (88.9％ vs.57.4％,respectively,P =0.022).Conclusion It revealed that the non-steroid treatment does not increase the incidence of acute rejection but also can decrease the incidence of de novo diabetes in the patients with HCC following liver transplantation and prolong the survival time of patients who met the Milan criteria.
