Key Social Determinants to Narrow the Gap between Health-adjusted Life Expectancy and Life Expectancy in Megacities

ObjectiveImprovement in the quality of life is reflected in the narrowing of the gap between health-adjusted life expectancy (HALE) and life expectancy (LE). The effect of megacity expansion on narrowing the gap is rarely reported. This study aimed to disclose this potential relationship.MethodsAnnual life tables were constructed from identified death records and population counts from multiple administrative sources in Guangzhou, China, from 2010 to 2020. Joinpoint regression was used to evaluate the temporal trend. Generalized principal component analysis and multilevel models were applied to examine the county-level association between the gap and social determinants.ResultsAlthough LE and HALE in megacities are increasing steadily, their gap is widening. Socio-economic and health services are guaranteed to narrow this gap. Increasing personal wealth, a growing number of newborns and healthy immigrants, high urbanization, and healthy aging have helped in narrowing this gap.ConclusionIn megacities, parallel LE and HALE growth should be highly considered to narrow their gap. Multiple social determinants need to be integrated as a whole to formulate public health plans.

The jejunum is the key factor in insulin resistance

BackgroundBiliopancreatic diversion (BPD) is more effective than Roux-en-Y gastric bypass (RYGB) on both insulin resistance and diabetes.ObjectivesBecause the major difference between the 2 procedures resides in the length of jejunal bypass, we investigated the role of the jejunum in insulin resistance.SettingUniversity hospital in Italy.MethodsInsulin sensitivity (IS) and secretion were measured before and 4 weeks after RYGB or BPD in 16 patients. A translational study was also conducted in 6 pigs, by isolating a jejunal loop with its vascular and nerve supply (Thiry-Vella loop [TVL]). TVL was doubly stomatized and bowel continuity restored by a side-to-side jejuno-jejunostomy. At baseline and 4 weeks postoperatively a glucose bolus was injected either in the stomach or in the TVL. Whole-body IS and jejunal heat shock proteins (HSPs) were measured. Primary porcine hepatocyte cultures were incubated with plasma or individual HSPs.ResultsWhole-body IS increased from 353.5 ± 26.7 to 442.0 ± 37.4 (P < .05) after RYGB and from 312.4 ± 14.9 to 441.2 ± 15.9 mL/m⁻²/min⁻¹ (P < .001) after BPD. Hepatic IS was unchanged after RYGB, while it increased from .3 ± .01 to .4 ± .1 (μM/pM) – 1 (P < .01) after BPD. Total insulin secretion rate remained unchanged after RYGB but decreased (from 58.3 ± 23.6 to 33.1 ± 7.8 nmol/m⁻², P < .05) after BPD. Jejunectomy in pigs enhanced IS (.3 ± .01 versus .2 ± .01 mM/pM, P < .001), while injection of glucose into TVL reduced it (.1 ± .01 versus .3 ± .01 mM/pM, P < .0001). The jejunum secreted HSPs, Hsp70, and GRP78, which impaired insulin signaling in hepatocyte cultures.ConclusionsThis study shows that jejunal bypass in both humans and pigs improves IS. Injection of glucose into the TVL in pigs determines insulin resistance. In response to glucose, the jejunum secretes HSPs that impair insulin signaling.     

糖尿病肾病内热证与肾功能及炎症因子的相关性研究

目的:观察糖尿病肾病不同分期内热证与肾功能及炎症指标的相关性。方法:收集202例糖尿病肾病患者的临床资料,采用酶联免疫吸附法检测微炎症指标,包括超敏C反应蛋白(high-sensitivity C-reactive protein,HS-CRP)、白细胞介素-6(interleukin-6,IL-6)、肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α),进行统计分析。结果:与非内热证组比较,中期、晚期内热证组24小时尿蛋白定量明显升高;晚期内热证组的血清肌酐明显升高,肾小球滤过率(glomerular filtration rate,GFR)明显降低;炎症因子CRP、IL-6、TNF-α随疾病进展均呈上升趋势;晚期内热证组与非内热证组比较,IL-6、TNF-α升高;中期HS-CRP与内热积分呈正相关,晚期TNF-α与内热积分呈正相关。结论:内热病机贯穿于糖尿病肾病的始终,与糖尿病肾病肾功能以及疾病进展密切相关;同时,内热积分与炎症因子HS-CRP、TNF-α的表达存在一定的相关性,这种相关性在疾病中期、晚期表现更加明显。     

2018—2019年度河北省城市结直肠癌筛查结果分析CSCD

目的分析2018—2019年河北省城市癌症早诊早治项目结直肠癌筛查结果。方法按照河北省城市癌症早诊早治中结直肠癌筛查流程,在石家庄市和唐山市选定社区中年龄40~74岁的当地居民,通过问卷调查后采用国家统一评估模型评估出高危人群,进一步通过结肠镜检查,发现早期结直肠病变,必要时通过病理进行确诊。结果 2018—2019年度,河北省城癌项目共计37849人完成结直肠癌危险因素问卷调查,评估结直肠癌高危人群6938例,总体高危率为18.33%。其中共有1230人参加了结肠镜检查,并完成病理检查465例(37.80%)。进行病理诊断者年龄主要分布在50~64岁。经结肠镜检查及病理诊断,共检出6例(0.49%)结直肠癌患者,其中结肠癌4例(0.33%)、直肠癌2例(0.16%)。结直肠癌癌前病变190例(15.45%),非进展期腺瘤/息肉250例(20.33%),炎性反应性肠道疾病168例(13.66%)。结论开展人群结肠镜筛查可以有效检出结直肠癌和癌前病变,实现结直肠癌的早期发现、早期诊断和早期干预。
