Objective To study the application and influential factors of urine tissue polypeptide specific antigen(TPS) for early detection and clinical outcome in bladder transitional cell cancers (BTCC). Methods Urine TPS in 76 cases of newly diagnosed BTCC,42 cases of recurrent BTCC,26 cases of postoperative BTCC with normal urine cytology,28 cases of benign bladder diseases,42 normal controls were determined by ELISA.The TPS levels were compared with the cystoscopic results and pathological findings.The relationship between urinary TPS level and the development and prognosis of BTCC was analyzed. Results The urine TPS level was not related to age and sex.The TPS levels in newly diagnosed BTCC group,recurrent BTCC group,postoperative BTCC with normal urine cytology group, bladder benign diseases group and control group were (341?403)U/L,(212?166)U/L,(168?115)U/L,(135?48)U/L and (81?37)U/L,respectively.There was significant difference between each other (all P

Objective To investigate the satlsfaction of senior outpatients over 60 years old,and explore the factors associated with their satisfaction so as to provide scientific references for improving quality of care at the hospital Methods A questionnaire survey was made by random sampling at the hospital.The outcomes subject to Ordinal regress Results The general satisfaction was as high as 82.77％ among these outpatients.Results of the Ordinal regression model showed seven factors significantly affecting such satisfaction rate,namely waiting time for registration,correct statement of medicine information,patience to hear patient's concerns,carefulness of inspection,time for doctor-patient communication,request for comments on therapy,and outpatient clinic seating conditions.Conclusion Senior outpatients tend to emphasize medical skills and medical service than waiting time at the hospital.This suggests better medical skills and service attitude as key to higher general satisfaction rate of senior outpatients.

Objective To analyze the effect of stroke duration on the cognitive function in the elderly population in Beijing.Methods Based on the Research Project of Beijing Chronic Disease Combined with Common Elderly Syndrome Community Management Practices,a cross-sectional study was used.From July 2013 to December 2014,the old population in 4 districts and a county (Xicheng District,Fangshan District,Tongzhou District and Yanqing County) in Beijing were sampled with the multi-stage,randomized and stratified sampling.A total of 3 024 subjects were enrolled in the study.The data were obtained from the questionnaires and clinical examinations.Mini-Mental State Examination (MMSE) was used as the evaluation index of cognitive function.The subjects were divided into either a normal cognitive function group (MMSE>26,n=1 878) or a cognitive impairment group (MMSE≤26,n=1 146) according to the MMSE scores.A multiple logistic regression model was used to analyze the effects of hemorrhagic stroke,ischemic stroke,and asymptomatic stroke,as well as disease duration on cognitive function.Results After adjusting for the confounding factors,such as sex,age,educational level,marriage,smoking,and alcohol consumption,the risks of occurring cognitive impairment in patients with hemorrhagic stroke in stroke duration for 1-3,4-10 and >10 years were OR 3.019 (95％CI 0.974-9.361,P=0.056),8.652 (95％CI 2.924-25.601,P<0.01) and 1.104 (95％CI 0.311-3.920,P=0.879) times of those without occurring stroke population;the risks of occurring cognitive impairment in patients with ischemic stroke in stroke duration for 1-3,4-10 and >10 years were 1.000 (95％CI 0.636-1.571,P=1.000),1.874 (95％CI 1.231-2.853,P=0.003),2.439 (95％CI 1.386-4.291,P=0.002) times of those without occurring stroke population.Stroke duration for 4-10 years in patients with hemorrhagic stroke and stroke duration for 4-10 and >10 years in patients with ischemic stroke were all the risk factors for occurring cognitive dysfunction.Conclusion For patients with stroke,stroke duration or long-term effects has a certain impact on cognitive function.

Objective To investigate the prevalence characters of peripheral artery disease (PAD) and associated factors among people aged 35 and above in Beijing. Methods This was a cross?sectional study. A total of 5 208 community?based individuals aged equal and above 35 in Beijing were chosen with stratified multistage random sampling method. Structure questionnaire was used to collected the information of demographic factors, habits and chronic disease history. Ankle brachial blood pressure was detected and ankle brachial index (ABI) was calculated. ABI was used to diagnose PAD (ABI≤0.90). Based on the 2010 Beijing Municipal Population Census, the age?and gender?specific weight?adjusted sample was acquired to estimate the prevalence of PAD and corresponding 95% confidence intervals ( CI ). Multivariate logistic regression analysis was performed to estimate the associated factors of PAD. Results The age?and sex?standardized prevalence of PAD was 3.84% (200/5 208, 95%CI 3.32%-4.36%). There was no significant difference between male and female (3.83%(102/2 664 ,95%CI 3.10%-4.56%) vs. 3.85% (98/2 544,95% CI 3.10%-4.60%), P=0.965). The prevalence of PAD in urban was higher than that in rural (4.34% (163/3 755,95%CI 3.69%-4.99%) vs. 2.55% (37/1 453,95%CI 1.74%-3.36%), P=0.001). Furthermore, the prevalence of PAD increased with age (Ptrend<0.01), and the difference between genders did not change with ageing (all P>0.05). In addition, age (OR=1.03, 95%CI 1.01-1.04), urban (OR=1.52, 95%CI 1.08-2.12), smoking ( OR=1.83, 95%CI 1.29-2.59), hypertension ( OR=1.61, 95%CI 1.17-2.22) and diabetes (OR=1.44, 95%CI 1.08-1.93) were related with increased risk of PAD in logistic regression analysis models. Conclusions The prevalence of PAD increases with age in Beijing and there are significant difference between urban and rural on prevalence of PAD. Age, urban, smoking, hypertension and diabetes are related with increased risk of PAD.

Objective To investigate the prevalence and risk factors of H-type hypertension among middle-aged and elderly people in Beijing community. Methods A cross-sectional study by recruiting 1 458 middle-aged and elderly people from a cohort of the "Beijing Longitudinal Study of Aging" in 2009 was conducted. All participants were asked to complete a standardized questionnaire, physical examination and laboratory examinations. Hyperhomocysteinemia was defined as homocysteine (Hcy) > 15 μmol/L, and H- type hypertension was defined as having hypertension and hyperhomocysteinemia simultaneously. The prevalence of H-type hypertension was estimated by using the results of 2000 Beijing population census to weight the data. Multivariate Logistic regression analysis was preformed to estimate the associated factors of H-type hypertension. Results The age was (69.48 ± 8.09) years, and the distribution of Hcy was skewed with the median of 16.56 μmol/L. After weight, the prevalence of hyperhomocysteinemia was 57.20% (834/1 458), and the prevalence of H-type hypertension was 35.32% (515/1 458), accounting for 59.47% (515/866) in patients with hypertension. The ageing, male, hyperuricemia, estimated glomerular filtration rate (eGFR) and insufficiency of fishes/ shrimps were independent risk factors of H-type hypertension ( OR = 2.30, 1.04, 1.02, 0.95 and 0.67; 95% CI 1.54-3.44, 1.02-1.06, 1.04-1.06, 0.94-0.97 and 0.46-0.97; P＜0.01 or＜0.05). Conclusions The proportion of H-type hypertension is high in the middle-aged and elderly people in Beijing community. Lowering uric acid, protection of renal function and intake sufficient fishes and shrimps might prevent and control H-type hypertension.

Objective To find out the prevalence of urinary incontinence(UI),as well as its impact on self assessed life quality in community dwelling elderly Beijing residents.Methods A total of 2 878 local elderly residents(≥ 65 years)were enrolled through stratified cluster random sampling from July 2013 to December 2014 in Beijing.A face-to-face questionnaire survey and physical examination were conducted by trained investigators.UI was screened using ICIQ SF.Prevalence of UI was adjusted by the standard population of Beijing and the number of elderly people with UI was estimated.Results The overall prevalence of UI was 24.6％.The morbidity of UI was 18.5％ in male and 29.8％ in female participants.The estimated number of elderly UI patients in Beijing was about 445 thousands,with 153 thousand male and 292 female patients.After adjustment for potential confounding demographic,lifestyle and chronic disease factors,logistic regression analysis revealed that UI was negatively correlated with several self-assessed measures,including quality of life,health,sleep quality,activities of daily life,sexual life and relationship with other people(all P＜0.05).Moreover,negative emotions in the last four weeks increased in the elderly with UI.Conclusions Nearly one quarter of the aged population,especially among aged women,in Beijing suffer from UI.UI severely affects the quality of life and emotions in aged persons.It is necessary to take early interventions to improve quality of life and promote healthy aging.

BACKGROUND: Colorectal carcinogenesis and progression are related to the gut microbiota and the tumor immune microenvironment. Our previous clinical trial demonstrated that berberine (BBR) hydrochloride might reduce the recurrence and canceration of colorectal adenoma (CRA). The present study aimed to further explore the mechanism of BBR in preventing colorectal cancer (CRC). METHODS: We performed metagenomics sequencing on fecal specimens obtained from the BBR intervention trial, and the differential bacteria before and after medication were validated using quantitative polymerase chain reaction. We further performed ApcMin/+ animal intervention tests, RNA sequencing, flow cytometry, immunohistochemistry, and enzyme-linked immunosorbent assays. RESULTS: The abundance of fecal Veillonella parvula ( V . parvula ) decreased significantly after BBR administration ( P = 0.0016) and increased through the development from CRA to CRC. Patients with CRC with a higher V. parvula abundance had worse tumor staging and a higher lymph node metastasis rate. The intestinal immune pathway of Immunoglobulin A production was activated, and the expression of TNFSF13B (Tumor necrosis factor superfamily 13b, encoding B lymphocyte stimulator [BLyS]), the representative gene of this pathway, and the genes encoding its receptors (interleukin-10 and transforming growth factor beta) were significantly upregulated. Animal experiments revealed that V. parvula promoted colorectal carcinogenesis and increased BLyS levels, while BBR reversed this effect. CONCLUSION: BBR might inhibit V. parvula and further weaken the immunomodulatory effect of B cells induced by V. parvula , thereby blocking the development of colorectal tumors.
