Blood lead level and Helicobacter pylori infection in a healthy population: A cross-sectional study

Abstract

The aim of this study was to investigate whether elevated blood lead level (BLL) is a risk factor for Helicobacter pylori infection. Upper gastrointestinal endoscopy was performed on 2,625 subjects who visited a university hospital for general health examination. H. pylori infection was detected using histologic examination with Giemsa staining, and BLLs were measured. The mean BLL was 2.83?±?1.31?μg/dL. The prevalence of H. pylori infection was 27.8%. The BLL was significantly higher in the H. pylori infection-positive group compared to the non-infected group (2.96?±?1.33?μg/dL vs. 2.78?±?1.30?μg/dL, p?<?0.001), which remained significant after adjusting for other confounders. H. pylori infection significantly increased as the BLL increased (OR: 1.143, 95% CI 1.068–1.223). We found a relationship between BLL elevation and H. pylori infection rate.     

营养教育咨询降低质子重离子治疗期间显著体重下降率

目的探讨以指南为依据的肿瘤放疗患者营养教育咨询方案，在降低质子重离子治疗期间显著体重下降发生率方面 的有效性。方法以质子重离子治疗期间的肿瘤放疗患者为研究对象，采用历史对照研究设计，方案实施前以2016年1月至12月 收治的患者为对照组，方案实施后以2018年1月至8月收治的患者为试验组。对照组在方案实施前仍实行原有的常规护理，试验 组给予以指南为依据的营养教育咨询方案。结果本研究共纳入713例肿瘤患者，其中对照组374例，试验组339例，两组平均年 龄为54岁和53岁，45%和49%为头颈部肿瘤患者。放疗期间对照组平均体重下降0.51 kg，平均体重丢失0.75%，显著体重下降 发生率为11.2%（42例）；试验组体重下降0.66 kg，平均体重丢失0.90%，显著体重下降发生率为9.4%（32例）。在控制放疗总剂量、 射线类型、肿瘤部位、同期化疗和性别的混杂因素影响后，试验组显著体重下降的风险下降了34%（OR=0.66，95%CI=0.48~0.91）。 结论以指南为依据的肿瘤放疗患者营养教咨询方案能够帮助改善质子重离子治疗期间的患者营养状态，有效降低显著体重下 降的风险。     

庄国康教授运用重潜搜风法治疗顽固性皮肤瘙痒的经验

瘙痒是皮肤科最常见症状,而顽固性瘙痒因其瘙痒剧烈、夜不能寐、持续时间长,常规中西医治疗无效,更是临床治疗的难点。庄国康教授在50余年的临床皮肤病诊疗过程中,积累了丰富而又宝贵的临床经验,认为痒必挟风,而顽固性瘙痒多伴情志失调,肝失疏泄,心神浮越,风火相煽,常规祛风之法疗效不显,故治疗多从心肝入手,运用重潜搜风法,选择金石和介壳类药物生龙骨、生牡蛎、石决明、珍珠母、灵磁石等为主确立核心处方,并根据皮疹颜色、形态以及患者整体辨证灵活配伍,取得了满意疗效。
