Objective An experimental study was undertaken to observe the effects of DFMO on the growth and apoptosis in bladder carcinoma EJ cells. Methods The methods of cell culture, living camera technique, eosin dying cell counting and DNA end labeling in situ were used to observe the effects of DFMO on the growth and apoptosis in bladder carcinoma EJ cells. Results Living camera technique showed that cell growth was significantly inhibited after five days of 4 mmol/L, 6 mmol/L, 8 mmol/L of DFMO were administrated compared with that of control group, and this variation was obvious with DFMO dosage increasing. The same was observed with eosin dying cell counting. Tunel method showed that apoptosis was induced by DFMO with 4 mmol/L, 6 mmol/L, and 8 mmol/L, but 6 mmol/L seems to be a suitable dosage. All these methods showed that if exogenous putrescence was added simultaneously, there was no difference significantly compared with that of control group both in cell proliferation and apoptosis. Conclusion The proliferation of bladder carcinoma EJ cell could be inhibited by DFMO and also apoptosis could be induced by DFMO.

Objective To evaluate the efficacy and safety of TUEVP vs TURP for treating benign prostatic hyperplasia(BPH).MethodsLiferatures on randomized controlled trials(RCT),non-randomized controlled trials(NRCT) and retrospective controlled trials of both Chinese and English studies about TUEVP vs TURP for the treatment of BPH all over the world were searched by Pubmed,Ovid,ScineceDirect,NGC,EBSCO,EMBASE,CNKI,CBM,as well as manual search of four Chinese journals: Chinese of Journal of Androloy,National Journal of Androlgy,Chinese Journal of Urology,Journal of Clinical Urology.Two reviewers independently screened the studies for eligibility,evaluated the quality and extracted the data from the eligible studies,with confirmation by cross-checking.Divergences of opinion were settled by discussion or consulted by the expert.Meta-analysis was processed by Rev Man 5.0,fail-safe number(Nfs) was performed by SAS8.0.ResultsSeventeen RCTs involving 2413 men were enrolled the inclusion criteria in Meta analysis.The baseline of patients' characteristics was comparable in all the studies.By evaluating the relevant indicators,side effects and complications between TUEVP and TURP,the statistically significant differences of pooled estimates suggested a benefit of TUEVP over TURP for bladder wash-out time,catheterization time,hospital stay,incidence of ED(20.6% vs 29.0%).In contrast,pooled estimates of the difference favoured TURP over TUEVP for MFR and incidence of postoperative secondary hemorrhage(7.9% vs 3.6%).ConclusionThis formal meta-analysis suggests that both TUEVP and TURP in patients with BPH provide comparable improvements,whose efficacy and safety is similar.While comparative analysis is limited by the methodological shortcomings of the underlying studies and the short follow-up,both TURP and TUEVP may offer distinct advantages.More high quality trials with large sample and longer follow-up are proposed,which will provide more evidence about evidence based medicine.

Objective To analyze the main clinical features and impact factors of simple renal cyst (SRC), and to provide evidence for the future prevation and cure of simple renal cysts.Methods In this crosssectional study,a total number of 91 433 participants(aged 18-98 years old) were included who underwent health examinations during 2012-2014.The main life styles and clinical features of each participants were recored,and blood biochemistry test, urinanalysis and renal ultrasonography were performed.Results The prevalence of SRC was 2.70％ (2 465 subjects were diagnosed by ultrasonography).It was higher in men than women(2.95％ vs.1.68％, P =0.00), which was increased with the increasing of age (respectively 0.37％, 0.57％, 1.30％ ,2.69％ ,4.46％ and 6.91％ in the group of ≤29year,30-39 year,40-49 year,50-59 year,60 -69 year and ≥70 year,P＜0.01).The maximum diameter of simple renal cysts were (2.6±1.7) cm.Age,rate of men, body mass index, glucose, total cholesterol, creatinine, urea nitrogen, and urinary protein positive rate, kidney stone prevalence were higher in SRC group(respectively (61.11±11.24)year vs.(51.37±13.72) year, 87.59％ vs.79.88％, (25.27 ± 3.19) kg/m2 vs.(24.97 ± 3.35) kg/m2, (6.09 ± 2.08) mmol/L vs.(5.70 ± 1.85) mmol/L, (5.11 ± 1.54) mmol/L vs.(5.02 ± 1.37) mmol/L, (90.71 ± 34.84) μmol/L vs.(80.72 ±28.04) μmol/L, (6.03±3.60) mmol/L vs.(5.55±5.15) mmol/L,7.46％ vs.4.25％ ,7.06％ vs.1.28％ ,P ＜0.01) ,but glomerular filtration rate, triglycerides, rate of like salty, drink, smoke was lower than the group withoutSRC((79.01±19.89) ml/(min· 1.73 m2) vs.91.74±21.8 ml/(min · 1.73 m2),(1.57±1.48) mmol/L vs.(1.69± 1.82) mmol/L, 4.38％ vs.7.94％, 22.68％ vs.30.75％, 24.91％ vs.30.97％;P＜ 0.01).But,there was no difference between these two groups in serum uric acid ((309.16± 85.79) μmol/L vs.(312.38±91.22) μmol/L,P＞0.05).SRC as a dependent variable of multivariate log regression analysis.The result showed the OR of age, gender, fasting blood glucose, urea nitrogen, glomerular filtration rate, positive urine protein,kidney stone were respectively 1.040, 1.862, 1.035, 1.005,0.982, 1.254, 4.526, 95％ CI =1.037 -1.045,1.643-2.110,1.017-1.053,1.000-1.010, 0.980-0.984, 1.068-1.473,3.812-5.374;P ＜0.01).While the OR of multiple SRC was 0.43,95％ CI: 0.210-0.867 (P＜0.05) , when kidney stone as a dependent variable.Conclusion Old-age males are high risk population of catching SRC.Kidney stone and positive urine protein are important risk factors of SRC.Meanwhile kidney stone more easily induce single and small SRC.SRC is a key risk factor to induce renal function decrease.Therefore, GFR is a sensitive index of renal disfunction that induced by SRC.

Objective To investigate the prevalence of influenza virus infections in infants and young children during the pandemic period of 2009 influenza A(H1N1)in Beijing.Methods Throat swabs were collected from children visited the affiliated Children's Hospital to Capital Institute of Pediatrics for influenza-like illness from June 1,2009 to February 28,2010.The specific gene segments of 2009 pandemic influenza H1N1 and seasonal influenza viruses were amplified from samples by real-time RT-PCR recommended by WHO and National Influenza Reference Center of China.Results Out of 4363 clinical samples tested by real-time RT-PCR,the total positive rate of influenza A viruses was 29.3%,including 623(14.3%)identified as 2009 pandemic influenza A(H1N1)and 657(15.1%)influenza A viruses without subtype identity.Among those pandemic influenza H1N1 positive,23 were severe cases with 5 deaths.The ages for 618 pandemic influenza H1N1 infected children with completed information were from 14 days to 16 years.The ratio of male to female wag 1.3:1.Among them,25.2% were patients in age group of 1 to 3 years old and distribution of children in age groups of 3 to 6 years old and 6 to 12 years old were similar(about 30.0%).During the survey period,it appeared only one prevalence wave of pandemic influenza H1N1.The positive rate of pandemic H1N1 increased in September and the peak(36.5%of positive rate)was in November and then declined to 2.7%in February 2010.The data from routine influenza virus surveillance from 20-30 clinical samples collected each week indicated an alternative prevalence of seasonal H3N2,pandemic H1N1 and influenza B during this study period.Respiratory syncytial virus(RSV)became predominant in children after the circulating of pandemic H1N1.Conclusion There was an epidemic of pandemic influenza H1N1 in children in Beijing from June 2009 to February 2010,especially in those of preschool and school aged children.Seasonal influenza viruses and pandemic influenza H1N1 were contributed alternatively.

Currently,the ethical review model for organ donation and transplantation in domestic hospitals is generally characterized by suddenness,unpredictability,tight time,difficulty in convening meetings and training committee members,as well as generally low quality and efficiency of ethical review,which cannot meet clinical needs and cause the waste of some scarce resources.The team of the Clinical Application Center of Human Organ Transplantation and the Ethics Committee of the First People's Hospital of Kunming combine more than 10 years of review practice experience,as well as continuously explore and optimize the ethical review process and operating procedures for organ donation and transplantation.The special application has been approved and jointly developed with Soochow University and the Medical Ethics Committee of Fujian Province to build a full-process information software system management platform for organ ethical review of donation and transplantation,giving the full play the advantages of the review information system in improving work efficiency and review quality,facilitating full-process information management,and conducting online training and learning for committee members,with a view to providing a specialized practical model for addressing the difficulties and challenges related to ethical review of human organ donation and transplantation.

Frailty denotes a nonspecific clinical condition characterized by a decrease of physiological reservation in multiple systems, which makes individuals extremely vulnerable to stressors. Frailty increases the incidence of adverse outcomes and death of patients. However, frailty is reversible and preventable. Therefore, this article reviews theoretical models, assessment tools and influencing factors of frailty in elderly patients with hematologic maligilancy, so as to provide references for medical staff to carry out frailty management and related research in elderly patients with hematologic maligilancy.
