In order to assess the effect of long-term versus short-term intravesical chemotherapy in preventing the recurrence of patients with non-muscle-invasive bladder cancer, we searched several databases with words as mesh terms and free text words to find all eligible randomized clinical trials (RCTs) for the comparison of the two strategies of instillation durations. "Observed-Expected events research (O-E)" and "Variance (V)" for calculating hazard ratio (HR) were used in Revman 5.2 software recommended by Cochrane Collabration for data analysis. Sensitivity and subgroup analysis were selected to minish heterogeneity. GRADEpro 3.6 profile recommended by Cochrane Collabration was employed for quality assessment of analyses. Finally, 13 eligible RCTs with 4216 patients were included in this review and 16 comparisons from 13 trials were involved for analysis. The pooled analysis revealed no significant difference between long-term and short-term duration [HR=0.99, 95% CI (0.89, 1.11), P=0.89]. Within the subgroup analysis, patients benefited from long-term instillations with a start regimen of one immediate instillation [HR=0.83, 95% CI (0.69, 1.00), P=0.05]. But patients were not suitable to receive long-term instillations with epirubicin (EPI) [HR=1.01, 95% CI (0.91, 1.13), P=0.78]. The progression rate was not reduced after long-term instillations [HR=0.96, 95% CI (0.66, 1.39), P=0.82]. From our results, patients should not receive introvesical chemotherapy more than half a year. In contrast, patients with one immediate instillation are preferred to have a long-term duration at least one year. Long-term instillations can not reduce the progression rate.

Objective To investigate the prevalence status and risk factors of mild cognitive impairment (MCI) in old people in pension facilities in Chongqing, China. Methods From October to November, 2015, the people above 60 years old in four pension facilities in Chongqing were cluster sampled. They were interviewed with Mini-Mental State Examination, Instrumental Activity of Daily Living Scale, self-made general situation questionnaire for the elderly and the Geriatric Depression Scale. Results There were 25 MCI patients identified in 84 old people selected, with the prevalence of 29.76%. MCI prevalence was different with the factors such as genders, educational levels, economical status, smoking, eating freshwater fish frequently, participating in outdoor activities frequently, playing Mahjong/chess/cards fre-quently, watching TV/listening to broadcast/reading newspaper frequently, participating in social activities frequently, having religious be-liefs, suffering high blood pressure (χ2>4.271, P<0.05). Based on multivariate Logistic regression analysis, male was the protective factor (OR=0.055, 95%CI:0.005~0.618), while high blood pressure was the risk factor (OR=8.281, 95%CI:1.278~53.646) to the MCI. Conclu-sion MCI is prevalent in old people in pension facilities in Chongqing, which needs intervention targeted to the risk foctors.

Objective To study the safety and efficacy of therapeutic endoscopic retrograde cholangiopancreatography (ERCP) in elderly patients with biliary and pancreatic diseases under the concept of enhanced recovery after surgery (ERAS). Methods 320 patients were enrolled in ERCP operation. Both ERAS elderly group (experimental group A, n = 58, above 75 years) and young and middle-aged group (control group B, n=202,below 60 years)underwent enhanced recovery after surgery,meanwhile traditional elderly group(control group C, n = 60, above 75 years) received traditional perioperative management. It had compared multiple clinical indexes between group A with B and group A with C during the preoperative, intraoperative, and postoperative period. Results The incidence rate of cholangiocarcinoma, multiple complications, nutrition screening ≥ 3 points, ASA scored III degree and Child-Pugh scored A-level in preoperative ERAS elderly patients were higher than that of the young and middle-aged group (P < 0.05); And its incidence rate of nausea and vomiting and abdominal pain,nutritional screening < 3 points and ASA scored I degree were lower than that of the middle-aged group (P < 0.05);the fasting and water- deprivation time of the ERAS elderly group was shorter than that of the traditional elderly group (P < 0.05). The intraoperative operation time of the elderly ERAS group was slightly longer than that of the traditional elderly group (P < 0.05). The duration of electrocardiographic monitoring and the first aerofluxus time of the elderly patients with ERAS were longer than that of the young and middle-aged group (P < 0.05). The success, failure rate, and complication rate of the elderly patients with ERAS were 91.38% (53/58) and 8.62% (5 /58), 3.45% (2/58), meanwhile the young and middle-aged group were 96.53% (195/202), 3.47% (7/202), and 4.95% (10/202), and with no statistical difference (P > 0.05). The mild pain in ERAS elderly group was more than that of in traditional elderly group, while the moderate, and severe pain was less than that of traditional elderly group (P < 0.05); The opioid use rate, endoscopic nasobiliary indwelling, first-time ambulation and aerofluxus, total hospitalization, and postoperative hospitalization time of ERAS elderly group was less than the traditional elderly group (P < 0.05). Conclusions With ERAS, the treatment effect of ERCP in elderly patients is similar to that in young and middle-aged people, and it has good safety and effectiveness.
