我国结直肠癌的发病率与死亡率逐年增加,约10%~30%新发结直肠癌患者可表现为急性肠梗阻,其中梗阻发生率较高的主要部位是左半结肠。急性梗阻性左半结肠癌患者的主要治疗方式仍是急诊手术（ES）,但术后并发症发生率及围手术期死亡率较高,自膨式金属支架（SEMS）被一些指南推荐为梗阻性结肠癌的初始治疗选择,SEMS可将部分ES转变为择期手术,支架置入后择期手术（SBTS）与ES相比不仅可改善患者的短期生存结局,且支架置入后新辅助化疗为梗阻性结肠癌的治疗提供了新的途径;就长期生存结果而言,选择SBTS还是ES存在一定的争议。对于支架置入后手术时机的选择尚未达成共识,有指南表明大约两周的短桥接间隔可使患者最大程度获益,因而可有效指导临床工作。肠道支架置入术目前看来是一种简单、有效的临时性或永久性的治疗手段。

In recent years, the incidence and mortality of colorectal cancer in our country have been increasing year by year．Around 10% to 30% of newly diagnosed colorectal cancer patients showed acute intestinal obstruction, which the left colon cancer has higher incidence．Emergency surgery（ES）is still the main treatment for patients with acute obstructive left colon cancer, but the incidence of postoperative complications and perioperative mortality are high．Self-expanding metallic stents（SEMS）can convert some emergency procedures into stent as bridge to surgery（SBTS）, which is recommended by some guidelines as the initial treatment option for obstructive colon cancer．SBTS can not only improve the short-term survival outcome of patients compared with ES, but also provide a new approach for the treatment of obstructive colon cancer with neoadjuvant chemotherapy after intestinal obstruction stent placement．The choice of SBTS versus ES is somewhat controversial in terms of long-term survival outcomes．There is no consensus on the timing of surgery after stenting, and current guidelines suggest that bridging intervals of approximately two weeks strike a balance between potential adverse events and long-term outcomes．At present, intestinal stenting is still a simple, feasible and effective temporary or palliative permanent treatment with few complications．

目的 明确上海市闵行区社区老人轻度认知功能障碍（MCI）发生现状,分析MCI发生的影响因素间的交互作用关系。方法 采用横断面研究方法,应用AD-8与CSI-D对该区2021年65岁以上老人MCI发生现状进行双量表评估。应用SPSS 26.0 软件,先后采用χ²检验分析受检老人吸烟、饮酒、慢性病等因素在不同检出情况的构成、二分类非条件Logistic回归分析MCI发生的影响因素,再将各因素依次纳入双因素交互作用分析模型,分析各变量对MCI发生的交互作用。结果 应用AD8与CSI-D双量表评估法具有较高的灵敏度,评估闵行区社区老人MCI阳性率为26.6%,高于其他研究,低年龄（OR=1.09,95%CI：1.04~1.14）、良好的健康心态（OR=1.67,95%CI：1.15~2.42）是减少老人MCI的保护因素,职业类型（OR=1.19,95%CI：1.04~1.38）、照料者类型（OR=1.56,95%CI：1.09~2.22）与老人MCI的发生存在相关关系。家庭月总收入与照料者类型之间、是否饮酒与照料者类型之间对老人MCI的发生存在交互作用（P均<0.05）。结论 保持良好的心态可以降低老人MCI发生风险,不同职业类型、照料者类型与老人MCI的发生具有相关关系,照料者选择保姆可能会增加老人MCI风险。

Objective To clarify the current situation of mild cognitive impairment（MCI）in the community elderly in Minhang District,Shanghai,and analyze the interaction relationship between the influencing factors of MCI．Methods A cross-sectional study method was used,and AD8 and CSI-D were used to evaluate the current situation of MCI in the elderly over 65 years old in this district in 2021．SPSS 26.0 software,chi-square test and binary unconditional Logistic regression model were used to analyze the composition of smoking,drinking,chronic diseases and other factors in different detected conditions and the influencing factors of MCI occurrence in the elderly．A factor interaction analysis model was used to analyze the interaction of each variable on the occurrence of MCI．Results The AD8 and CSI-D double-scale evaluation method had high sensitivity．The positive rate of MCI in the community elderly in Minhang District was 26.6%,which was higher than other studies．Younger age（OR=1.09,95%CI：1.04~1.14）,good health mentality（OR=1.67,95%CI：1.15~2.42）were protective factors for reducing MCI in the elderly,occupation type（OR=1.19,95%CI：1.04~1.38）,caregiver type（OR=1.56,95%CI：1.09~2.22）were correlated with the occurrence of MCI in the elderly．There were interaction effects between the total monthly household income and the type of caregivers,whether drinking or not and the type of caregivers on the occurrence of MCI in the elderly（all P<0.05）．Conclusions Maintaining a good attitude can reduce the risk of MCI in the elderly．Different occupational types and types of caregivers are related to the occurrence of MCI in the elderly．Caregivers choosing nanny may increase the risk of MCI in the elderly．

目的 了解门诊老年患者补充与替代医学（CAM）使用现状及影响因素。方法 采用便利抽样法,选取2020年11月—2021年2月广东省某三甲医院老年科门诊就诊的老年患者作为研究对象,调查方法采用一般资料调查表和CAM使用情况调查表进行横断面调查。应用二元Logistics回归分析探讨门诊老年患者使用CAM的影响因素。结果 参与调查的123例老年患者中,有75例（61.0%）老年患者使用CAM,使用CAM的项目主要为中草药、药膳等中国传统医学项目。支付方式是门诊老年患者是否使用CAM的影响因素,使用医保支付的患者较公费、自费患者更愿意使用CAM（OR=5.054,95%CI：1.452~17.590,P<0.05）。结论 CAM在门诊应用广泛,我们应充分发挥我国传统医学优势,为老年人疾病防治提供更多的思路。政府层面也可进一步提高医保覆盖范围,让更多的患者有经济能力可以接受安全、有效的治疗。

Objective To understand the current situation and main influencing factors of career decision-making difficulties of higher vocational medical students, and put forward improvement countermeasures. Methods The method of stratified cluster sampling was adopted, with 740 full-time medical students from a vocational college in Guangzhou being investigated. Results The average score of career decision-making difficulty of medical students surveyed in higher vocational colleges was (3.55±0.647), in which the average score of the career planning exploration was the lowest (3.42±0.797), and the average scores of other dimensions from low to high were career goal exploration (3.49±0.766), career information exploration (3.58±0.678) and career self-exploration (3.69±0.659). The results of one-way analysis of variance (ANOVA) showed that there were significant differences in the scores of career decision-making difficulties of medical students in higher vocational colleges among different majors, the major being the first choice or not, and different living places (P<0.05). The results of multiple stepwise regression analysis showed that family location, school guidance courses for career planning, part-time or trainee experience, school activities (employment guidance lectures, career planning competitions, etc.), being optimistic about the employment prospects of their majors, schools providing sufficient employment information, and having participated in innovation and entrepreneurship competitions were predictors of difficulties in career decision-making for medical students (P<0.05). Conclusions The difficulty of career decision-making of medical students in higher vocational colleges was in the middle level. Schools can establish a systematic evaluation and intervention system aiming at career decision-making difficulties by carrying out targeted career guidance, and build practice and employment service platform to improve the career decision-making difficulties of medical students in higher vocational colleges, and to provide strong support and security for students. The government can enhance policy guidance for medical students in higher vocational colleges to apply for primary hospital.
