Objective To analyze the risk factors of delayed bleeding after colonic polyp resection.Methods 700 patients with colonic polyps admitted to General medical treatment Hanzhong 3201 hospital from January 2022 to May 2023 were included as the research object,and all patients were treated with colonoscopy polypectomy.According to whether Post-procedural bleeding(PPB)occurred after operation,they were divided into two groups:the group with PPB occurrence(n=85 cases)and the group without PPB occurrence(n=615 cases).The general data,clinical data and operation-related data of the two groups were analyzed by univariate analysis.Multivariate Logistic regression was used to analyze the risk factors of postoperative PPB,and receiver operating characteristic curve was drawn to analyze the predictive value of risk factors.Results 700 patients in this study were all treated by colon polypectomy,and 85 patients(12.14％)developed PPB within 30 days after operation,that is,the incidence of PPB in this study was 12.14％.There was significant difference in sex,age,hypertension and treatment history of thrombosis between the two groups(P＜0.05).There was significant difference in the morphology,diameter and surgical methods between the two groups(P＜0.05).Multivariate Logistic regression analysis showed that polyp morphology(stalk),polyp diameter(＞1 cm),Endoscopic mucosal resection(EMR)and Endoscopic submucosal dissection(ESD)were the risk factors for postoperative PPB(P＜0.05).The ROC curve showed that the area under curve of polypoid-shaped is 0.653,95％CI is 0.616-0.688,the AUC of polyp-diameter is 0.741,95％CI is 0.707-0.773;and in the way of operation,the AUC of argon plasma coagulation/ESD is 0.730,95％CI is 0.713-0.802,the AUC of EMR/ESD is 0.541,95％CI is 0.498-0.584,the AUC of APC/EMR is 0.604 and 95％CI is 0.565-0.641.Conclusion Polyp pedicled,diameter＞1 cm,EMR and ESD are the risk factors for postoperative PPB.

Objective:To explore the correlation between medication adherence and quality of life (QOL) in aged pa‐tients with hypertension from communities .Methods :Chinese questionnaire of quality of life in patients with cardi‐ovascular disease (CQQC) and Morisky medication adherence scale were used to investigate and analyze 197 aged pa‐tients with hypertension from communities .Results:Total score of CQQC was (78.69 ± 9.36) scores in the 197 aged patients with hypertension from communities .In which ,77 cases (39.09% ) possessed good medication adherence , and 120 cases ( (60. 91% )) with poor adherence to medication . Compared with those with poor adherence to medi‐cation,therewassignificantriseintotalscoreofCQQC [(75.73±8.52)scoresvs.(83.31±8.76)scores ,P<0.01] .Pearson correlation analysis indicated that QOL was significant positively correlated with medication adher‐ence (r=0.397 , P<0.01) .Conclusion:Community health staff should pay attention to influencing factors of med‐ication adherence in aged patients with hypertension ,take individualized and targeted interventional measures to im‐prove their adherence to medicationand quality of life .

Objective: To assess the relationships between nutritional risks, nutritional support, and doctors' knowledge related to nutritional risks. Methods: 217 pre-operative patients and 41 doctors in the same general surgical wards were surveyed by using NRS2002 and self-developed questionnaires in a Beijing hospital. Results: The overall prevalence of pre-operative nutritional risks was 15.7%. Patients with gastrointestinal and/or malignant diseases had higher risks than others(P values were both less than 0.001). The nutritional support rates were 14.7% among patients with nutritional risks, and 2.2% among those without risks. The EN: PN ratio was 1∶ 2. A majority of doctors had misconceptions in nutritional risk screening and the effectiveness of nutritional supports. Their clinical practices were not consistent with their knowledge. Related trainings were required. Conclusions: Patients with gastrointestinal and/or malignant diseases have higher possibilities of nutritional risks. The nutritional supports rates are generally low. Doctors' knowledge related to nutritional risk screening is insufficient. More training opportunities are suggested to enhance the application of NRS2002 and appropriate nutritional supports.

Objective To evaluate the preoperative undernutrition, nutritional risks, and nutritional support in general surgical wards. Methods The nutritional risks of 217 new in-patients in general surgical wards in a Beijing-based hospital were assessed using nutrition risk screening 2002 ( NRS 2002 ) and the medical records were reviewed. Results The overall prevalence of preoperative undernutrition and nutritional risks was 7.4% and 14.7% respectively, most of which occurred in patients with gastrointestinal diseases and malignant diseases. Nutritional supports were provided to 18.8% of patients with undernutrition, 12.5% of patients with nutritional risks,3.0% of patients without undernutrition, and 2.7% of patients without nutritional risks. The enteral nutrition:The application of nutritional support should be further improved in general surgical wards.
