As a new type of medical service mode, day surgery significantly alleviates the contradiction between supply and demand of medical resources. Since 2009, day surgery center in West China Hospital of Sichuan University has gradually carried out endoscopic gastrointestinal(GI) polypectomy, continuously explored and practiced the centralized management mode of GI polyps. The integrated management process included pre-hospital management, clinical pathway during hospitalization, and extended service after discharge. The overall-management database for day surgery patients was established, guiding the clinical practice and standardizing clinical behavior based on various clinical studies, which help day surgery managers make clinical decisions, and achieve the management objectives of fine management, quality and safety normalization for day surgery.

Objective: To investigate the status of insomnia, Internet addiction, and depressive symptoms among medical students and to analyze the effect of Internet addiction on insomnia and the mediating role of depressive symptoms, in order to provide a basis for the development of targeted interventions and measurements for medical students. Methods: A stratified whole group sampling method was used to select full-time college students from three medical universities in Anhui Province. The Chinese version of Insomnia Severity Index (ISI), Internet Addiction Test (IAT) scale and 9-item Patient Health Questionnaire (PHQ-9) were used to evaluate the symptoms of insomnia, Internet addiction and depressive in students. A multivariate Logistic regression analysis was used to explore the factors influencing insomnia among medical students and to analyze the relationship between insomnia with Internet addiction and depressive symptoms, respectively. Results: The overall rate of Internet addiction was 49.5%, depressive symptoms was 39.5%, insomnia was 18.6%. High academic stress, and the presence of surrounding people diagnosed with COVID-19 were associated with a higher risk of insomnia ( P <0.05). The higher the level of Internet addiction (mild, OR =2.60; moderate/severe, OR =4.21) and depression. (mild, OR =6.35; moderate/severe, OR =19.32), the higher the risk of insomnia. Mediated effect analysis showed that Internet addiction had a direct predictive effect ( β =0.02, P <0.05) on insomnia and also indirectly affected insomnia through depression (indirect effect=0.07，95% CI =0.06-0.08). Conclusion The detected rates of insomnia, Internet addiction and depressive symptoms are high among medical students in Anhui Province, and Internet addiction and depressive symptoms are risk factors for insomnia, which should be given more attention and appropriate interventions when necessary to improve their physical and mental health.

Objective:To investigate the application value of ambulatory surgery mode in inguinal hernia repair.Methods:The retrospective and descriptive study was conducted. The clinical data of 416 patients with inguinal hernia who were admitted to the Meishan People′s Hospital, West China Hospital of Sichuan University from January 2020 to January 2022 were collected. There were 374 males and 42 females, aged 52(range, 25-70)years. All patients underwent inguinal hernia repair with the ambulatory surgery mode. Observation indicators: (1) surgical situations; (2) follow-up. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) Surgical situations. Of the 416 patients, 258 patients underwent laparoscopic transabdominal preperitoneal inguinal hernia repair (TAPP) under general anesthesia and 158 patients underwent open inguinal hernia repair under local anesthesia (98 cases of Lichtenstein repair and 60 cases of preperitoneal repair). The intraoperative measured diameter of hernia ring defect and operation time of the 416 patients were 1.9 (range, 0.9-3.2)cm and 52 (range, 35-80)minutes. The duration of hospital stay of the 416 patients <48 hours, including 395 cases with the duration of hospital stay <24 hours. There were 21 patients with delayed discharge including 12 cases as post-operative pain, 8 cases as adverse reactions to general anesthesia, and 1 case as postoperative seroma. (2) Follow-up. All 416 patients were followed up for 12 months after surgery. During the follow-up period, there was no serious complication such as recurrent inguinal hernia, wound infection, intestinal fistula or obstruction. At 1 month after surgery, ultrasound examination of the inguinal area did not reveal any serum swelling or seroma. The postoperative visual analogue scale of pain in patients undergoing laparoscopic TAPP was 2.70±0.10 at postoperative 3 days and 0 at postoperative 12 months. The above indicator in patients undergoing Lichtenstein repair and pre-peritoneal repair was from 3.20±0.20 and 3.00±0.10 at postoperative 3 days to 0 and 0 at post-operative 12 months, respectively. All patients did not experience chronic pain for more than 3 months. All 416 patients conducted satisfaction surveys over the phone, and all of them were very satisfied or satisfied, with a satisfaction rate as 100.00%(416/416).Conclusion:Ambulatory surgery mode in inguinal hernia repair is safe and feasible.

Objective:To explore whether the degree of skeletal muscle atrophy in obese individuals under the influence of colorectal cancer is more severe than that in non-obese individuals.Methods:The clinical data of patients who underwent radical resection of colorectal cancer in our department from Jul 2020 to Dec 2021 was collected. Sixty-four obese patients were included and 64 non-obese patients were matched according to propensity score. At the same time, 51 obese patients were collected from non-tumor patients and matched with 51 non-obese patients. The psoas muscle index (PMI) of included patients was analyzed and compared.Results:The PMI of patients with colorectal cancer was significantly lower than that of corresponding non-tumor patients, regardless of gender and body weight (both P<0.05). The PMI of obese patients with colorectal cancer was significantly lower than that of non-obese patients ( P<0.05). Conclusions:The impact of colorectal cancer on skeletal muscle atrophy in obese individuals is greater than that in normal weight individuals. Therefore, the skeletal muscle status of obese patients with colorectal cancer should be evaluated more comprehensively.

Consultation system is one of the eighteen core systems. Excellent consultation supervision can assist clinical departments to maximize cooperation efficiency. This article, concentrating on timeliness, built an individual-group-organization model based on the organizational behavior theory and actual conditions, and took management actions from three aspects, including changing personal behavior attitude, adjusting organizational performance plan and establishing task-based groups. Timeliness data in October and November 2018 were selected retrospectively one month before and one month after the new actions. The timely rate of consultation increased from 76.69% to 82.62% with a significant difference(P=0.000 2).
