不同健康状况的中老年人社会资本量表的信度及效度评价

目的 评价中老年人社会资本量表的信效度，探索其在不同健康状况的中老年人群间的区分度。方法 针对已编制的中老年人社会资本量表，采用多阶段分层随机抽样方法，在四川省成都市及泸州市共抽取1 367名50岁及以上中老年居民进行问卷调查。运用Cronbach’s α系数、Pearson相关系数、t检验、探索性因子分析等方法评价量表的信度和效度。结果 1 367名中老年调查对象的社会资本量表总Cronbach’s α系数为0.67，各维度条目与总分的相关系数在0.30～0.79之间，具有良好的信度；探索性因子分析表明，14个条目提取出5个特征根大于1的因子，累积方差贡献率为68.84%；现患慢性疾病的中老年病例组人群的个人社会资本得分、家庭社会资本得分、社团社会资本得分、社区社会资本得分及社会资本总得分均低于未患病的对照人群组，宏观社会资本得分高于对照人群组，且差异均有统计学意义 (均 P＜0.01)，提示该量表具有较好的区分度。结论 中老年人社会资本量表具有较好的信度和效度，且对不同健康状况的50岁及以上中老年人中有较好的区分度。     

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.     

社区“5+1”糖尿病分阶段达标管理对2型糖尿病患者生存质量干预效果分析

目的 分析社区"5+1"糖尿病分阶段达标管理对2型糖尿病患者生存质量的干预效果及其影响因素，为提高患者生存质量提供依据。方法 采用分层整群抽样的方法在山西省、江苏省和宁夏回族自治区选择12个社区卫生服务中心，分别作为干预组（管理方式：社区"5+1"糖尿病分阶段达标管理）、对照组[管理方式：依据《国家基本公共卫生服务规范（2011年版）》的相关要求]，进行为期2年的随访观察。采用面对面问卷调查的方式，收集患者的人口学信息等基本信息；采用健康调查简表（SF-36）对患者在干预前后测量生存质量。采用SAS 9.4软件进行双重差分法以及多重线性回归模型分析。结果 基线时共纳入2 467名研究对象，终末时共1 924人接受了为期2年完整的随访管理。干预后，干预组、对照组患者生理健康维度（PCS）、心理健康维度（MCS）评分变化净差值分别为13.6分、29.8分。多重线性回归分析结果显示，影响患者PCS得分的主要因素有年龄、医保类型、基线PCS得分以及所在地区，影响患者MCS得分的主要因素有年龄、医保类型、基线MCS得分、是否合并高血压以及所在地区。结论 社区"5+1"糖尿病分阶段达标管理对2型糖尿病患者生存质量的干预效果较好。

PurposeThis article reviews state of the science of preoperative risk factors associated with postanesthesia care unit (PACU) pediatric respiratory complications.DesignAn integrative review.MethodsA search of PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), MEDLINE, Scopus, Cochrane, and Joanna Briggs Institute databases was performed. Thirty-one articles, published between 2006 and 2018, were appraised for quality and the level of evidence using the Johns Hopkins Nursing Evidence-Based Practice Model.FindingsThese articles were grouped into the following categories: age, American Society of Anesthesiologists status, gender, airway comorbidities, syndromes, anomalies, pulmonary comorbidities, ethnicity, obesity, neurologic comorbidities, and cardiac comorbidities.ConclusionsEvidence identified significant preoperative and anesthesia risk factors that are associated with PACU pediatric respiratory complications. This article reveals the importance for the perioperative team to identify, assess for, communicate, and develop a management plan for pediatric respiratory complications.     

早期十全大补汤联合肠内营养乳剂治疗胃癌术后(气血两虚证)喂养不耐受临床评价

目的探讨早期使用十全大补汤联合肠内营养乳剂(TP)治疗胃癌术后(气血两虚证)发生喂养不耐受(FI)的影响因素及对营养指标、中医证候积分的影响。方法回顾性分析术后早期行十全大补汤联合TP治疗的80例胃癌术后(气血两虚)患者的病历资料,根据是否出现FI分为耐受组(34例)和不耐受组(46例)。FI的相关影响因素进行单因素及多因素分析,并观察FI对患者营养指标、中医证候积分的影响。结果单因素分析显示,患者术后第1天下床活动时间、开始肠内营养(EN)的时间、使用营养泵、早期灌肠与FI的发生密切相关(P <0. 05);多因素Logistic回归分析显示,患者第1天下床活动时间≥2 h[OR=0. 022,P=0. 001,95%CI(0. 002,0. 223)]、使用营养泵[OR=0. 021,P=0. 000,95%CI(0. 003,0. 162)]是FI发生的独立危险因素;术后10 d,耐受组患者白蛋白(ALB)、血红蛋白(Hb)升高水平优于不耐受组(P <0. 05),中医证候积分显著低于不耐受组(P <0. 05)。结论胃癌术后(气血两虚证)患者早期给予十全大补汤联合TP治疗开始后,患者第1天下床活动时间不短于2 h、使用营养泵能有效减少FI的发生,并改善了患者的营养状态,减轻了中医临床症状。

目的:观察丹参川芎嗪注射液联合西药治疗对急性缺血性脑卒中患者脑组织的保护作用及对预后的影响。方法:以268例急性缺血性脑卒中患者为研究对象,按随机数字表法分为研究组和对照组各134例,2组均予西药治疗,研究组予以丹参川芎嗪注射液联合治疗,2组均随访至12周。治疗前后检测2组患者的血清炎症相关因子[超敏C-反应蛋白(hs-CRP)、肿瘤坏死因子-α(TNF-α)、白细胞介素-6 (IL-6)、白细胞介素-8 (IL-8)]、血管内皮生长因子(VEGF)、神经元特异性烯醇化酶(NSE)和S-100β水平,随访评定患者治疗12周内的美国国立卫生研究院卒中量表(NIHSS)评分和日常生活能力量表(BI)评分。结果:治疗3周,2组hs-CRP、TNF-α、IL-6和IL-8水平均低于入院时(P<0.01);研究组各因子水平均低于对照组(P<0.01)。2组血清NSE和S-100β水平均较入院时降低(P<0.01),而VEGF水平较入院时升高(P<0.01)。研究组血清NSE和S-100β水平均低于对照组,VEGF水平高于对照组,差异均有统计学意义(P<0.01)。2组治疗后一时间点的NIHSS评分均低于同组治疗前一时间点(P<0.01),而2组治疗后一时间点的BI评分均高于同组治疗前一时间点水平(P<0.01)。治疗6周和12周,研究组的NIHSS评分均低于对照组(P<0.01),而BI评分均高于对照组(P<0.01)。结论:丹参川芎嗪注射液联合西药治疗可以有效减轻急性缺血性脑卒中患者的血管炎症反应程度、血管内皮细胞和脑组织的损伤程度,促进大脑神经细胞修复,提高患者卒中后的生活能力,防止卒中后肢体发生功能障碍,改善患者预后。     

Epidemiology and risk factors of colorectal cancer in China

In China, colorectal cancer (CRC) ranked fourth and fifth in the highest incidence and mortality rates of all malignancies in 2018, respectively. Although these rates are below the world average, China placed first worldwide in the number of new CRC cases and CRC-related deaths because of its comparatively large population. This disease represents a threat to the health of population and incurs a heavy economic burden on the society and individuals. CRC has various risk factors, including age, sex, lifestyle, genetic factors, obesity, diabetes, gut microbiota status, and precancerous lesions. Furthermore, incidence and mortality rates of CRC are closely related to socioeconomic development levels, varying according to regional and population characteristics. Prevention is the main strategy to reduce incidence and mortality rates of CRC. This can be achieved through strategies stimulating lifestyle changes, healthy diet habits, and early screening for high-risk individuals. To reduce the burden of CRC, public health officials should promote prevention and management of modifiable risk factors through national policies. The rising incidence and mortality rates of CRC in China may be timely curbed by clarifying specific epidemiological characteristics, optimizing early screening strategies, and strictly implementing diagnosis and treatment guidelines. Thus, this study aimed to collect and report the current research status on epidemiology and risk factors of CRC in China.
