肿瘤性复杂性胸壁缺损的修复策略及对肿瘤治疗的积极影响

复杂性胸壁缺损的修复一直是一项极具挑战性的工作。肿瘤性复杂性胸壁缺损的修复决策及其执行困难是限制胸壁肿瘤治疗方法选择及影响预后的重要因素之一。皮瓣解剖学研究的深入、胸壁支持结构重建技术的进步、显微外科技术的发展、麻醉护理的发展、对综合治疗的重视和治疗手段的进步等,使传统认为不可切除的胸壁肿瘤得以彻底地切除和安全有效地修复,从而使与缺损修复相关的肿瘤切除及辅助治疗的禁忌证缩减到最小程度,有效地提高了胸壁肿瘤患者的生存质量,并很大程度上延长了生存率。作者以湖南省肿瘤医院整形外科15年565例胸壁肿瘤切除后修复重建的临床资料为依据,充实了胸壁肿瘤切除及修复的策略:(1)可靠的胸壁骨性支架重建;(2)有效的软组织修复;(3)麻醉及护理与手术团队的合作;(4)系统有序的综合治疗。并进一步明确了复杂胸壁肿瘤切除及重建的细节理念,包括胸部肿瘤治疗中加强多学科合作的密切性和科学性,整形外科医生参与肿瘤治疗整体规划的主动性和时机前移等。     

Total bilirubin independently predicts incident metabolic syndrome among community-dwelling women

BackgroundMetabolic syndrome (MetS) is related to the increased risk of major cardiovascular diseases (CVD). The link between high serum total bilirubin (TBL) is cross-sectionally related to MetS and its components. However, whether serum TBL predicts incidence of MetS and its components remains inconclusive.MethodsThe present study included 893 women aged 70 ± 9 years from a rural village. We examined the relationship between serum TBL and MetS based on the modified criteria of the National Cholesterol Education Program's Adult Treatment Panel (NCEP-ATP) III report in a cross-sectional (N = 893) and cohort (N = 288) data.ResultsIn the cross-sectional study, serum TBL (β = 0.536, p < 0.001) as well as age, alcohol consumption, exercise habits, history of CVD, SUA, GGT, and ALT was significantly and dependently associated with number of MetS components, but in the cohort study serum TBL was not associated with number of MetS components. Compared with the 1st tertile of serum TBL (0.20–0.55 mg/dL), multivariate-adjusted odds ratio (95% confidence interval) for the 2nd -3rd tertiles of serum TBL (0.54–2.00 mg/dL) was 0.70 (0.51–0.95) in the cross-sectional study and 0.41 (0.21–0.81) in the cohort study.ConclusionsOur data demonstrated an independently negative association between serum TBL and MetS in Japanese community-dwelling women.     

POLG 基因变异致线粒体病一家系分析

目的分析POLG基因变异致线粒体病的临床表型及基因变异。方法回顾分析于2019年5月就诊,并经采集外周血DNA进行医学外显子、外显子-内含子交界区靶向二代测序和一代验证,1个确诊为POLG基因变异致线粒体病家系的临床资料。结果先证者,男,10岁,与其同卵双胎哥哥均有相同的体征,深感觉受损、腱反射消失、肌肉可疑萎缩。先证者3个兄姐先后于1岁多夭折。提取患儿及其父母的外周血,先证者及同卵双胎哥哥POLG基因均存在G.2558A(p.R853Q)、c.2890T(p.R964C)复合杂合变异,分别来源于患儿父母亲。结论 POLG基因复合杂合变异线粒体病家系成员有不同的表型;POLG相关疾病,即使同种基因变异,其临床异质性也较大。     

甘肃省和政县农村老年性白内障防盲项目的卫生经济学评价研究

目的 对2014-2016年在甘肃省和政县开展的白内障综合防盲干预项目进行卫生经济学评价。设计 横断面调查。 研究对象 甘肃省和政县2014-2016年老年性白内障手术前407例患者及术后半年109例患者。方法 对所有调查对象进行卫生经济学问卷调查。通过净效益法、成本效益分析法和成本效果分析法评价项目产生的经济效益和总成本。主要指标 直接成本、间接成本、直接经济效益、间接经济效益、总成本、总效益、净效益、成本效益比、成本效果比。结果 2014-2016年项目期间甘肃省和政县白内障所致总体疾病经济负担为2142.28万元。白内障手术产生的总效益为3398424.98元，总成本为2939125.20元，净效益为459299.78元，效益成本比为1.16:1。项目每投入1万元可降低50岁以上白内障患者导致的0.027%的致盲率和0.164%致残率；项目每降低1%的50岁以上白内障患者的盲率，需投入36.47万元；每降低1%50岁以上白内障患者的残率，需投入6.11万元。结论 在甘肃省和政县开展的老年性白内障防盲综合干预项目具有较好的产出回报比和较高的防盲技术效率。（眼科，2020，29： 298-303）     

Increase in Streptococcus pneumoniae serotype 3 associated parapneumonic pleural effusion/empyema after the introduction of PCV13 in Germany

IntroductionPediatric pneumococcal pneumonia complicated by parapneumonic pleural effusion/empyema (PPE/PE) remains a major concern despite general immunization with pneumococcal conjugate vaccines (PCVs).MethodsIn a nationwide pediatric hospital surveillance study in Germany we identified 584 children <18 years of age with bacteriologically confirmed PPE/PE from October 2010 to June 2018. Streptococcus pneumoniae was identified by culture and/or PCR of blood samples and/or pleural fluid and serotyped.ResultsS. pneumoniae was identified in 256 of 584 (43.8%) children by culture (n = 122) and/or PCR (n = 207). The following pneumococcal serotypes were detected in 114 children: serotype 3 (42.1%), 1 (25.4%), 7F (12.3%), 19A (7.9%), other PCV13 serotypes (4.4%) and non-PCV13 serotypes (7.9%). Between October 2010 and June 2014 serotype 1 (38.1%) and serotype 3 (25.4%) were most prevalent, whereas between July 2014 and June 2018 serotype 3 (62.7%) and non-PCV13 serotypes (15.7%) were dominant. Compared to children with other pneumococcal serotypes, children with serotype 3 associated PPE/PE were younger (median 3.2 years [IQR 2.1–4.3 years] vs. median 5.6 years [IQR 3.8–8.2 years]; p < 0.001) and more frequently admitted to intensive care (43 [89.6%] vs. 48 [73.8%]; p = 0.04). Seventy-six of 114 (66.7%) children with pneumococcal PPE/PE had been vaccinated with pneumococcal vaccines. Thirty-nine of 76 (51.3%) had received a vaccine covering the serotype detected. Thirty of these 39 breakthrough cases were age-appropriately vaccinated with PCV13 and considered vaccine failures, including 26 children with serotype 3, three children with serotype 19A and one child with serotype 1.ConclusionFollowing the introduction of PCV13 in general childhood vaccination we observed a strong emergence of serotype 3 associated PPE/PE in the German pediatric population, including a considerable number of younger children with serotype 3 vaccine breakthrough cases and failures. Future PCVs should not only cover newly emerging serotypes, but also include a more effective component against serotype 3.
