山东济宁某医院门诊患者幽门螺杆菌感染检测分析

目的探讨分析山东济宁地区自然人群幽门螺杆菌的流行病学特征,为防治提供参考。方法于2012-05/2013-05采集山东济宁市第一人民医院胃镜室就诊患者580例,采用14C-UBT检测法与血清幽门螺杆菌Ig G抗体ELISA法对所有研究对象的幽门螺杆菌感染情况进行检测,并结合相关问卷调查,分析其流行病学特征。结果该医院门诊患者幽门螺杆菌总感染率45.2%,其中男性感染率59.5%,女性感染率40.5%,不同性别感染幽门螺杆菌感染阳性率差异比较无统计学意义(P0.05);各年龄段幽门螺杆菌的感染率从31.4%~53.1%不等,农民、商人及工人幽门螺杆菌感染率分别为78.6%、70.7%、68.8%,高于其他职业,差异有统计学意义(P0.05),但各年龄段间幽门螺杆菌感染率的差异比较无统计学意义(P0.05)。幽门螺杆菌感染与吸烟、饮酒、家庭收入无关,差异无统计学意义(均P0.05),与个人饮食卫生习惯、家庭教育程度及职业有关,差异有统计学意义(P0.05)。结论山东济宁市某医院门诊患者幽门螺杆菌总感染率较高,其感染率与职业、个人及家庭生活习惯等有关。     

Lower body mass index and higher height are correlated with increased varicocele risk

To evaluate the anthropometric indexes in subjects with varicocele compared to controls and the incidence of varicocele in different body mass index (BMI) groups for the purpose of exploring the association between varicocele and anthropometric indexes. A comprehensive literature search was conducted by using PubMed, MEDLINE, EMBASE databases and Cochrane Library up to February 2019. A systematic review and meta‐analysis was conducted by STATA, and Newcastle–Ottawa Scale was utilised for assessing risk of bias. Ultimately, 13 articles containing seven case–control studies and six cross‐sectional studies with 1,385,630 subjects were involved in our study. Pooled results demonstrated that varicocele patients had a lower BMI (WMD = ?0.77, 95% CI = ?1.03 to ?0.51) and a higher height than nonvaricocele participants, especially in grade 3 varicocele patients. Subgroup analyses showed that normal BMI individuals had a higher risk of varicocele than obese or overweight individuals and a lower risk than underweight individuals. In conclusion, this study indicates that varicocele patients have a lower BMI and a higher height than nonvaricocele participants. Moreover, men with excess bodyweight have a lower incidence of varicocele compared to normal weight or underweight people. That is to say, high BMI and adiposity protect against varicocele and high BMI is associated with a decreased risk of varicocele.     

Research progress on the biomimetic remineralization of hard tooth tissues based on polyamide-amine dendrimer

聚酰胺—胺树枝状聚合物（PAMAM）作为一种新型超支化大分子聚合物,因其出色的化学和生物学特性,一直被众学者称之为“人工蛋白”。 PAMAM的特点是存在内部空腔,并含有大量的反应性末端基团,这些结构使得PAMAM可以被用作仿生大分子,模拟天然有机基质在牙体组织表面进行仿生矿化,即PAMAM作为有机模板调控矿物质成核以及晶体的生长,以此来建造比传统的异体材料更加理想的牙体修复材料。本文就 PAMAM 诱导牙体硬组织仿生矿化的研究进展作一综述。

基层医疗卫生服务整合的国际经验及对我国的启示

目的:总结典型国家基层卫生服务提供中实现医防整合的经验,为我国基层医疗卫生服务整合提供借鉴。方法:本研究方法为文献研究。结果:在个人层面,英国、泰国、古巴培养全科医生作为"守门人"并将其作为提供医防整合服务的主体;在机构层面,各国基层机构组成服务网络,内部强调跨学科合作;在体系层面,通过横向合作和有序的首诊与转诊协调服务;国家立法保障和健康保险筹资等引导支持基层医疗卫生服务整合。结论:培养和配置高质量的医防一体的全科医生、促进机构跨学科融合、通过立法和筹资体系予以保障是各国提供基层整合型服务的核心,值得我国基层医防服务整合借鉴。     

人格特征对男性喉鳞状细胞癌患者术后近期心理状况的影响

目的 探讨人格特征对喉鳞状细胞癌（LSCC）患者术后近期心理健康状况的影响。方法 纳入2017年1月—2019年12月在湖北省肿瘤医院行手术治疗的119例男性LSCC患者，术后5~7 d采用SCL-90、SAS、SDS自评量表评估术后心理状态，采用EPQ问卷测评患者的人格特征。多元线性逐步回归方法分析LSCC患者术后近期SAS和SDS评分的影响因素。结果 男性LSCC患者术后SCL-90、SAS、SDS得分显著高于中国常模（P≤0.05），EPQ中精神质（P）量表和神经质（N）量表得分高于中国常模（P<0.01）。男性LSCC患者术后躯体化、强迫、焦虑、抑郁、敌对、恐怖、偏执、精神病性因子得分均显著高于中国常模（P<0.05）。家庭收入、手术方式、术后近期是否行放化疗、P和N人格特征是术后SAS评分的影响因素（均P<0.01）；家庭收入、手术方式、术后近期是否行放化疗和N人格特征是术后SDS评分的影响因素（P<0.01）。结论 LSCC患者术后近期存在抑郁、焦虑等心理障碍；具有P和N人格特征；家庭收入、手术方式、术后近期是否行放化疗以及P和N人格特征是影响术后SAS及SDS评分的独立危险因素。     

Review of clinical characteristics,immune responses and regulatory mechanisms of hepatitis E-associated liver failure

Hepatitis E virus (HEV) is the most common cause of acute liver failure (LF) and one of the most common factors causing acute injury in acute-on-chronic LF (ACLF). When HEV-related LF occurs, a series of changes take place in both the intrahepatic environment and extrahepatic microenvironment. The changed types and distribution of immune cells (infiltrating macrophages and increased lymphocytes) in liver tissue, as well the increased proinflammatory cytokines and chemokines in the blood, indicate that the occurrence and progression of HEV-related LF are closely related to immune imbalance. The clinical features and immune reaction in the body during HEV-related acute LF (ALF) and ACLF are complicated. This review highlights recent progress in elucidating the clinical manifestations of HEV-associated ALF and ACLF and discusses the corresponding systemic immune changes and possible regulatory mechanisms.
