Objective To explore the value of preoperative ultrasound indicators in predicting the difficulty of laparoscopic cholecystectomy (LC), in order to predict the risk of LC surgery and reduce the blindness of surgery. Methods The preoperative ultrasonographic parameters of 257 cases included gallbladder size, gallbladder wall thickness, gallbladder mucosal surface, bile sound transmission in gallbladder, maximum diameter of gallstone, and gallstone incarceration in gallbladder neck. Postoperative data included operation time, intraoperative blood loss, whether drainage tube was placed, whether transfer to abdominal surgery, and postoperative complications. The average operation time of the 257 cases was calculated and called the standard operation time, and the operation that exceeded the standard operation time, intraoperative bleeding ≥100 mL, postoperative drainage tube placing, and conversion of abdominal operation were defined as difficult operation. According to this standard, 257 patients were divided into the easy group and the difficult group. The χ² test was used for univariate analysis to identify the risk factors of difficult LC operation. Logistic multiple regression analysis was performed to determine the independent risk factors for predicting LC difficulty. Results According to unifactor analysis, preoperative ultrasound indicators: gallbladder size >50 cm², gallbladder wall thickness >4 mm, maximum diameter of gallstone >2 cm, gallbladder neck stone incarceration, and poor bile ultrasound transmission in gallbladder were risk factors for LC difficulty. Logistic multiple regression analysis confirmed that gallbladder size, gallbladder wall thickness, poor bile ultrasound transmission in gallbladder and stone incarceration in gallbladder neck were independent risk factors for difficult LC. Conclusions Ultrasound examination of gallbladder before operation could objectively evaluate the difficulty of LC, and had certain predictive value for guiding the surgeon to select LC cases.

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.

Besides,to relevant literatures of domestic and aboard were also reviewed. Results Two patients were hospitalized for abdominal discomfort, their average age was 66. Imageological examination showed splenic space-occupying. The neoplasms were composed of round,oval and spindle cells and were arranged in whorls and a spiral or storiform growth pattern,mixed with abundant lymphocytes and plasma cells and a few neutrophils with focal bleeding and necrosis. Immunohistochemically,varying degrees, tumor cells showed the expression of at least one of the FDC markers,including CD21 and CD23 protein except with CD35,with scattered positive EBER in situ hybridization. Conclusion Inflammatory pseudotumor-like follicular dendritic cell sarcoma of the spleen is a rare low-grade malignant tumor associated with EBV infection,which is older female predominated and with a inert biological behavior.The best treatment of the tumor is to complete surgical removal.Using reasonable application of immunohistochemical markers, in situ hybridization combined with histopathology are helpful for correct diagnosis.
