Confounded association between proton pump inhibitor use and risk of biliary tract cancer: Result from three cohorts

Recent epidemiological studies suggested that proton pump inhibitor (PPI) use was associated with an increased risk of biliary tract cancer (BTC), however, confounders were not adequately controlled. Our study aimed to evaluate PPI use and subsequent risk of BTC and its subtypes in three well-established cohorts. We conducted a pooled analysis of the subjects free of cancers in UK Biobank (n = 463 643), Nurses' Health Study (NHS, n = 80 235) and NHS II (n = 95 869). Propensity score weighted Cox models were used to estimate marginal HRs of PPIs use on BTC risk, accounting for potential confounders. We documented 284 BTC cases in UK Biobank (median follow-up: 7.6 years), and 91 cases in NHS and NHS II cohorts (median follow-up: 15.8 years). In UK biobank, PPI users had a 96% higher risk of BTC compared to nonusers in crude model (HR 1.96, 95% CI 1.44-2.66), but the effect was attenuated to null after adjusting for potential confounders (HR 0.95, 95% CI 0.60-1.49). PPI use was not associated with risk of BTC in the pooled analysis of three cohorts (HR 0.93, 95% CI 0.60-1.43). We also observed no associations between PPI use with risk of intrahepatic (HR 1.00, 95% CI 0.49-2.04), extrahepatic bile duct (HR 1.09, 95% CI 0.52-2.27) and gallbladder cancers (HR 0.66, 95% CI 0.26-1.66) in UK Biobank. In summary, regular use of PPIs was not associated with the risk of BTC and its subtypes.     

VAC结合游离植皮治疗儿童大面积皮肤缺损疗效观察及对患儿生活质量的影响

目的:探讨负压创面治疗技术(Vacuum assisted closure,VAC)结合游离植皮治疗儿童大面积皮肤缺损疗效及对患儿生活质量的影响。方法:选取2015年2月-2019年2月笔者医院收治的60例大面积皮肤缺损患儿作为研究对象,按照随机数表法分为干预组和对照组,每组30例。对照组采用游离植皮术治疗,干预组在对照组的基础上结合VAC治疗,以皮片成活时间、皮片成活率、换药次数及住院天数评估疗效,以长海痛尺分级法评估患儿疼痛等级,以抑郁自评量表(Self-rating depression scale,SDS)、焦虑自评量表(Self-rating anxiety scale,SAS)评估患儿心理状态,以术后不良反应发生率评估患儿预后情况,以自制生活质量表评估患儿生活质量水平。结果:干预组患儿皮片成活时间、换药次数与住院天数均小于对照组,差异有统计学意义(P<0.05)。干预组患儿皮片成活率为93.33%高于对照组的76.67%,差异有统计学意义(P<0.05)。干预组治疗后疼痛感、SDS与SAS评分低于治疗前,且低于对照组,差异有统计学意义(P<0.05)。干预组患儿术后不良反应发生率为6.67%显著低于对照组23.33%,差异有统计学意义(P<0.05)。两组治疗前活动能力、心理健康及社交能力均低于治疗后,干预组治疗后活动能力、心理健康及社交能力均高于对照组(P<0.05)。结论:VAC结合游离植皮治疗儿童大面积皮肤缺损疗效显著,能有效降低患儿生理疼痛与心理焦虑,减少伤口感染等不良反应的发生,提高患儿生活质量,具有推广价值。     

A comparison of the relationships between psychosocial factors,occupational strain,and work ability among 4 ethnic teacher groups in China

The present study compared the level of occupational strain and work ability among Han, Hui, Uygur, Hui, and Kazakh teachers, and explored ethnic differences based on the associations of psychosocial factors at work, occupational strain, and work ability. A cross-sectional survey was conducted among 2,941 teachers in primary and secondary schools in Xinjiang Province, China. Psychosocial factors, occupational strain, and work ability were measured using the Occupation Stress Inventory—Revised Edition (OSI-R) and Work Ability Index. Han and Hui teachers experienced reduced work ability compared with Uygur and Kazakh teachers, and this finding was caused, in part, by exposure to psychosocial factors at work. The vocational and psychological strains caused by these factors play an important role in reduced work ability among all ethnic teacher groups. The findings indicate the importance of taking action to reduce occupational strain for promoting teachers' work ability in multiethnic workplaces.     

Liguzinediol对阿霉素诱导的慢性心衰大鼠心功能的影响

目的 通过阿霉素（Dox）复制大鼠慢性心力衰竭（CHF）模型，观察Liguzinediol对CHF大鼠心功能的影响。方法 通过血流动力学观察Liguzinediol对Dox（腹腔注射，2 mg/kg）诱导的CHF大鼠左心室内压最大上升/下降速率(±dp/dt_max)、左心室内压(LVSP)、动脉收缩压(ASP)、动脉舒张压(ADP)和心率(HR)的变化；观察Liguzinediol对血清一氧化氮（NO）、一氧化氮合成酶（NOS）、超氧化物歧化酶（SOD）、肿瘤坏死因子-α（TNF-α）和白细胞介素-6（IL-6）以及血浆中丙二醛（MDA）的影响。结果 Liguzinediol能增加LVSP、+dp/dt_max、ASP、ADP、AP、HR，降低-dp/dt_max(P<0.05~0.01)；降低NO、iNOS以及MDA的浓度，同时增强了SOD的活性(P<0.05~0.01)；抑制IL-6和TNF-α的生成(P<0.05~0.01)。结论 Liguzinediol可明显改善Dox诱导的CHF大鼠血流动力学指标，减少模型大鼠炎症因子的释放以及抑制氧自由基的生成。

消风散合凉血五根汤联合西药治疗成人过敏性紫癜性肾炎临床疗效及对患者血表皮生长因子、血小板活化因子乙酰水解酶的影响

目的观察消风散合凉血五根汤联合西药治疗成人过敏性紫癜性肾炎(HSPN)的临床疗效及对患者血表皮生长因子(EGF)、血小板活化因子乙酰水解酶(PAF-AH)的影响。方法将90例成人HSPN患者按照随机数字表法分为2组。对照组45例予常规西医治疗;治疗组45例在对照组基础上加服消风散合凉血五根汤治疗。2组均治疗8周。比较2组治疗前后中医证候评分、血肌酐(Cr)、尿素氮(BUN)、24 h尿蛋白定量、尿红细胞计数(U-RBC)、尿微量白蛋白尿肌酐比值(UACR)、估算肾小球滤过率(e GFR)、血EGF、PAF-AH水平,并统计2组临床疗效及不良反应情况。结果治疗组总有效率88.89%,对照组总有效率68.89%,治疗组疗效优于对照组(P<0.05)。治疗后2组各项中医证候评分及总分均降低(P<0.05),治疗组治疗后各项中医证候评分及总分均低于对照组(P<0.05)。治疗后2组Cr、BUN、24 h尿蛋白定量、U-RBC、UACR均降低(P<0.05),e GFR升高(P<0.05);治疗组治疗后Cr、BUN、24 h尿蛋白定量、U-RBC、UACR均低于对照组(P<0.05),e GFR高于对照组(P<0.05)。治疗后2组血EGF、PAF-AH水平均降低(P<0.05),治疗组治疗后血EGF、PAF-AH水平均低于对照组(P<0.05)。治疗组不良反应率(11.11%)低于对照组(26.67%,P<0.05)。结论成人HSPN在西医治疗基础上,加用消风散合凉血五根汤可提高临床疗效,不仅可改善临床症状,还能改善肾功能,降低糖皮质激素不良反应,其机制之一可能与其下调血EGF、PAF-AH水平有关。
