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.

Objective To investigate the effect of standardized rehabilitation nursing on functional recovery of cervical spondylotic myelopathy (CSM) after anterior operation. Methods Sixty patients were divided into two groups: observation group (n = 30) and control group (n = 30). Routine nursing was carried out in the control group and standardized rehabilitation nursing measures were carried out in the observation group. At the time of discharge, 1,3,6 months after discharge, the JOA score of spinal cord function of the Japanese Orthopaedics Association, the NDI score of cervical spine disability index, the VAS score of visual analogue of pain, the score of self-care ability of life were taken. The length of hospitalization of the two groups and incidence of postoperative complications were recorded. Results There were significant differences in average hospitalization time, postoperative complications, recovery of spinal cord function, recovery of cervical spine function and ability of living self-care between the observation group and the control group after operation (P<0.05). The average hospitalization time in the observation group was lower than that in the control group (P<0.05), and the scores of spinal cord function and self-care ability after operation were higher than those in the control group (P<0.05). The score of cervical disability index and the incidence of postoperative complications were lower than those of the control group (P<0.05). Conclusion Standardized rehabilitation nursing may promote the recovery of spinal cord and cervical spine function, reduce hospital stay, reduce postoperative complications, improve the self-care ability of patients and improve the quality of life.

       目的   基于Nomogram初步构建膝骨关节炎（KOA）患者术前衰弱的风险预测模型。方法   便利选取172例于2021年12月—2022年8月在广州市某三甲医院关节外科接受择期膝关节置换术的KOA患者为研究对象，依据衰弱的发生与否分为衰弱组（n=111）和非衰弱组（n=61），通过单因素分析筛选变量，纳入Logistic回归分析，并构建列线图模型。结果   单因素分析结果显示年龄、BMI、膝关节疼痛年限、合并症、抑郁、焦虑、疼痛、睡眠障碍、营养状况等在不同组间比较差异存在统计学的意义（P＜0.05）。多因素Logistic回归分析表明，BMI异常（OR=3.360）、膝关节疼痛年限＞5年（OR=14.188）、抑郁（OR=5.608）、睡眠障碍（OR=25.480）是KOA患者术前衰弱的独立危险因素（P＜0.05）。基于此，建立了预测膝骨关节炎患者术前衰弱风险的列线图预测模型。结果显示C-index为0.915，校正曲线接近理想曲线，ROC曲线下面积（AUC）为0.919（95%CI：0.878~0.961），可见该预测模型具有较好的区分度和准确度。结论   根据BMI、膝关节疼痛年限、抑郁以及睡眠障碍这四个独立危险因素，可以准确地预测膝骨关节炎患者术前衰弱的风险。
