Objective To analyze the efficacy and safety of different minimally invasive operations[endoscopic re-trogradebiliary drainage(ERBD)、endoscopic nasobiliary drainage(ENBD)、percutaneous transhepatic cholangial drainage(PTCD)] for choledocholithiasis complicated with acute cholangitis to provide reference for clinical treatment retrospectively. Methods A total of 151 patients with choledocholithiasis complicated with acute cholangitis at Department of Emergency Surgery in our hospital from January 2019 to December 2020 were included and divided into four groups based on the four treatment strategies, including non-surgical treatment. Changes in leukocyte count, bilirubin levels, and liver function before and after treatment, as well as postoperative recovery, complication rates, length of hospital stay, and prognosis were compared among patients who underwent different surgical treatments. Results There were significant improvements in leukocyte count, percentage of neutrophils, and liver function of the patients underwent ENBD or ERBD operation (P<0.05). The total bilirubin and direct bilirubin were significantly reduced after ERBD, ENBD, and PTCD operations (P<0.05). Patients undergoing ERBD, ENBD, or PTCD demonstrated faster recovery times, fewer complications, shorter hospital stays, and lower mortality rates compared to those managed conservatively. Conclusions ERBD and ENBD as minimally invasive therapeutic modalities for the management of choledocholithiasis complicated with acute cholangitis, exhibit remarkable clinical efficacy, coupled with a high degree of safety and reliability. These techniques significantly enhance the long-term minimally invasive cure rate, thereby establishing them as the preferred treatment strategies. Tailored to the patient's specific clinical conditions, such as the severity of infection, stone dimensions, and the use of oral anticoagulant therapy, clinicians can formulate individualized minimally invasive treatment strategies, facilitating the optimal attainment of therapeutic objectives.

Objective To develop nurses'knowledge,attitude and practice questionnaire on medication management for patients with dysphagia,and test its reliability and validity.Methods Based on the evidence-based summary of the best evidence of medication management for patients with dysphagia,guided by the the-ory of knowledge,attitude and practice,the basic dimensions and item pool of the questionnaire were deter-mined through group discussion,Delphi expert consultation and pre-investigation.In order to revise the ques-tionnaire,437 nurses from 10 tertiary hospitals in Jiangsu Province were conveniently selected for investigation,and the reliability and validity of the questionnaire were tested according to the survey results.Results The nurses'knowl-edge,attitude and practice questionnaire on medication management for patients with dysphagia included 43 items in three dimensions.The three dimensions were analyzed by exploratory factors,and six common factors with characteristic roots>1 were extracted.Two factors were extracted from the knowledge dimension,and the cumulative variance contribution rate was 74.958%,One factor was extracted from the attitude dimen-sion,and the cumulative variance contribution rate was 77.655%.Three factors were extracted from the prac-tice dimension,and the cumulative variance contribution rate was 72.274%.The factor load of each item was 0.618-0.902,Cronbach's α coefficient of the total questionnaire was 0.949,and the test-retest reliability was 0.909.The overall content validity coefficient of the questionnaire was 0.922,and the content validity coeffi-cient for each item was 0.800-1.000.Conclusion The nurses'knowledge,attitude and practice questionnaire on medication management for patients with dysphagia developed in this study has good reliability and validi-ty,and could be used as an effective tool to evaluate the status quo of nurses'medication management for pa-tients with dysphagia.

Objective:To carry out an overview of systematic reviews on interventions to prevent the recurrence of diabetic foot ulcer (DFU) patients.Methods:Systematic reviews or Meta-analysis on interventions to prevent DFU recurrence were electronically retrieved from databases such as China National Knowledge Infrastructure, WanFang Data, VIP, China Biology Medicine disc, Joanna Briggs Institute (JBI) Evidence-Based Healthcare Center Database, Cochrane Library, PubMed, Embase, CINAHL and Web of Science. The search period was from database establishment to April 20, 2023. Two researchers independently searched and screened literature, and extracted data, and used AMSTAR 2 software and the quality evaluation criteria for systematic review of JBI Evidence-Based Healthcare Center to evaluate the methodological quality of the included literature. GRADE evaluation system was used for quality assessment of outcome indicators (DFU recurrence rate, effectiveness of measures to prevent DFU recurrence) .Results:A total of 24 systematic reviews were included. Studies showed that monitoring and intervention of foot skin temperature, therapeutic shoes or insoles, comprehensive intervention measures, and specific surgical methods could reduce the recurrence rate of DFU, while foot self-care, foot exercise, health education, and psychological intervention had no statistical effect on preventing DFU recurrence. The methodological quality of systematic reviews was generally low. The reports of four articles were relatively complete, 18 articles had certain defects, and two articles had serious defects. The evaluation of evidence quality showed that there were three pieces of moderate-quality evidence, seven pieces of low-quality evidence, and 30 pieces of extremely low-quality evidence.Conclusions:Existing evidence suggests that foot skin temperature monitoring and intervention, therapeutic shoes or insoles, comprehensive intervention measures, and specific surgical methods (such as Achilles tendon lengthening, metatarsophalangeal joint replacement, metatarsal head resection and so on) have a positive impact on preventing DFU recurrence. Rigorous and high standard research is still needed to verify the controversial issues, so as to provide reliable evidence for future clinical practice and studies.

Lectins are proteins responsible for recognizing the signals of sugar molecules in the body. Sialic acid-binding immunoglobulin-like lectins (Siglecs) regulate the innate and adaptive immune responses in the tumor microenvironment by recognizing the glycan structure containing sialic acid and mediating downstream signals through immune receptor tyrosine inhibitory motifs. In recent years, a variety of tumor treatment strategies targeting the sialic acid-Siglecs axis have been introduced, including sialoglycoprotein-mediated drug delivery and antibody mediated inhibition of Siglecs from recognizing tumor surface ligands. In the future, by combining with glycoprotein nanotherapy, antibody therapy and gene therapy, Siglecs can be used to accurately locate tumor targets and release the anti-tumor immunity, so as to achieve the purpose of effective cure of tumors.

China’s chronic disease management suffers from problems such as unclear institutional function， insufficient information technology application， and weak regulation support. On the basis of current chronic disease management condition in China， this paper proposes to apply the concept of “people-centered” integrated health management to community chronic disease management and discusses the content and procedure of establishing an integrated community-based chronic disease management model driven by massive databases. The model innovatively combines technology integration， data integration and service integration， and can accurately and efficiently realize the "people-centered" full-course health management of various chronic diseases. Shanghai has provided integrated community-based chronic disease management service for 1.98 million citizens through applying this model. The model warrants further effectiveness and economic evaluation. This study provides precious experience for the development of chronic disease prevention and treatment in China.

OBJECTIVE: To observe the clinical prognosis and surgical treatment results in patients with postinfarction ventricular septal rupture, and to discuss the risk factors, methods & timing of treatment. METHODS: From January 2006 to February 2019, 23 patients with postinfarction ventricular septal rupture were admitted to the department of cardiac surgery, Peking University People's Hospital, including 12 males (52.2%) and 11 females (47.8%), aged (64.26 ±11.09) years. Among them, 18 cases underwent operation, and 5 cases did not receive surgical treatment. The clinical data and follow-up data were summarized retrospectively. RESULTS: Among the patients treated with operation, the average time from perforation to operation was (19.39 ±13.67) d, including 6 cases (33.3%) of perforation within 1 week, 6 cases (33.3%) within 2 to 4 weeks and 6 cases (33.3%) more than 4 weeks. Emergency surgery was performed in 11 cases (61.1%) because of hemodynamic instability, and selective operation in 7 cases (38.9%). Direct enlarged patch was used in 13 cases (72.2%), and some infarct exclusion techniques were used in 5 patients (27.8%). In 18 cases, coronary artery bypass grafting was performed in 12 cases (66.7%). Of all the surgical patients, 7 (38.9%) died during hospitalization. Compared with the survival patients, the perioperative death patients had earlier perforation [(1.83±0.75) d vs. (5.22 ±4.66) d, P=0.019] and higher emergency operation rate (100% vs. 36.4%, P=0.009) and lower simultaneous bypass grafting rate (28.6% vs. 90.1%, P=0.008). The median follow-up time was 2 years (3 months to 10 years). 2 patients died of heart failure in 2 months after operation, and 9 cases (50.0%) survived for a long time. Of the 5 patients who had not been treated, 2 died while waiting for operation, and 3 patients who refused surgery died within 1 week after discharge. CONCLUSION Surgery is an effective treatment for patients with acute myocardial infarction complicated with ventricular septum perforation. The best time for operation should be determined by real-time evaluation and monitoring, combined with the situation of patients. Concomitant coronary artery bypass grafting may be beneficial to these patients.

BACKGROUND: The balloon dilatation technique plays an important role in the correction of kyphosis. A balloon catheter can enlarge the spinal cavity in kyphoplasty followed by injection of bone cement under low pressure to lay a foundation for the stability of the spine. OBJECTIVE: To explore the feasibility of balloon dilation with injectable calcium sulfate cement for tibial plateau fractures and to analyze its clinical effect. METHODS: Twenty-four upper tibia specimens of the adults were taken to make the Schatzker Ⅲ collapsed fracture model of the tibial plateau. Then, these specimens were randomized into three groups: the standard group was subjected to poking reduction with autologus bone grafting and screw internal fixation, the bone cement group was inflated with balloon dilatation followed by calcium sulfate cement injection, and the combined group was treated with fixation with cancellous bone screws and balloon dilatation followed by injection of calcium sulfate cement. The general situation of reduction and fixation was observed and the reduction effect was measured. RESULTS AND CONCLUSION: (1) Fixation effect in the model: All three models were well reset, and the average displacement of the standard group, the simple bone cement group and the bone cement screw group was (-0.22±0.62), (-0.23±0.67), and (-0.20±0.69) mm, respectively. There was no significant difference in the displacement between the three groups (P ＞ 0.05). (2) Clinical application: One case of Schatzker type Ⅱ fracture of the left tibial plateau was treated with cancellous bone screw fixation and balloon dilatation followed by injection of calcium sulfate cement. X-ray results showed calcium sulfate cement was visible at 3 postoperative days. At 30 postoperative days, the patient presented with good joint range of motion, and the calcium sulfate was partially absorbed on the X-ray film. At 60 postoperative days, the patient appeared to have no joint extension disorder, and fracture healing and absorption of calcium sulfate as shown by X-rays. To conclude, the balloon dilation with injectable calcium sulfate cement for the treatment of tibial plateau fracture is feasible and has clinical value.

Objectives:To describe the early and long-term survival of off-pump coronary artery bypass grafting(OPCAB)and to analyze the impact and risk factors of peri-operative events on mortality and long-term survival in OPCAB patients aged over 75 years old. Methods:From January 2001 to December 2012,233 patients aged over 75 underwent OPCAB in our hospital, 173 cases (74.25%) were male,the average age was (77.1±2.3) years.The perioperative data was retrospectively collected.Binary Logistic regression was used to define the risk factors related to the perioperative events and mortality.Follow-up was performed regularly post-surgery. Univariate analysis and Cox regression model were used to find out factors affecting the long-term outcomes. Results:Fifteen out of 233 patients died during the perioperative period. Binary Logistic regression showed that preoperative arrhythmia (OR=6.767, P=0.002),IABP ( intraoperative, post-operative) (OR=4.292, P=0.040;OR=19.455, P＜0.001), ICU stay time (OR=1.500, P=0.001), mechanical ventilation time (OR=1.004, P=0.002), reintubation or tracheotomy (OR=30.000, P＜0.001), re-thoracotomy (OR=26.750, P＜0.001), postoperative cerebral infarction (OR=5.889, P=0.041) were risk factors of perioperative mortality. The remaining 218 patients were followed up for a mean of (92.84±45.52) months, 121 patients died during follow-up. The survival rate at l, 3, 5, 8 and 10 years was 90.99%, 87.55%, 85.31%, 68.93% and 56.70%, respectively. Univariate analysis showed that sex(male), hypertension, preoperative arrhythmia, reintubation or tracheotomy were risk factors of the long-term mortality (P＜0.05). Cox regression analysis showed that reintubation or tracheotomy (HR 4.387, 95%CI=1.876-10.259,P＜0.010) was the independent risk factor affecting the long-term survival. Conclusions:Preoperative arrhythmia, IABP (intraoperative, postoperative), ICU stay time, mechanical ventilation time, reintubation and tracheotomy, re-thoracotomy, postoperative cerebral infarction are risk factors of perioperative mortality. Reintubation or tracheotomy is the independent risk factor affecting the long-term survival.Taken together, OPCAB in patients aged over 75 is associated with favorable perioperative and long-term outcome,and it serves a safe and effective operative strategy for coronary artery revascularization in patients aged over 75.

OBJECTIVETo explore the clinical efficacy and toxicity of CLAT protocol (cladribine, cytarabine and topotecan) for treating patients with refractory acute myeloid leukemia (R-AML).

METHODSA total of 18 patients with R-AML (median age 37 years, range 18 to 58 years; male n = 16, female n = 2) were treated with CLAT protocol, which consisted of cladribine 5 mg/m(2)/d, i.v. on days 1-5, cytarabine 1.5 g/m(2)/d, i.v. on days 1-5, topotecan 1.25 mg/m(2)/d, i.v. on days 1-5 and G-CSF 300 µg/d subcutaneous injection on day 6 until neutrophile granulocyte recovery.

RESULTSOut of 18 patients 2 died of severe infection before the assessment. Among 16 evaluated patients, 10 (55.6%) achieved complete remission (CR), and 2 (11.1%) achieved partial remission (PR), the overall response rate was 66.7%, the rest 4 patients did not respond (NR). The median overall survival time and DFS for the CR patients was 9.5 months (95%CI: 6.7-16.64) and 9.5 months (95%CI: 6.1-16.7) respectively. The 1 year OS and DFS rates were 45% and 46.9%, respectively. All patients developed grade 4 of granulocytopenia and thrombocytopenia, the median duration was 13 (range 2 to 21) days and 12 days (range 2 to 21), respectively, all patients developed infection, 2 patients died of severe infection. The most common non-hematological side effects included nausea, vomiting, diarrhoea, rash, aminotransferase or bilirubin elevation and were grade 1 to 2.

CONCLUSIONThe CLAT protocol seems to have promising for the treatment of refractory AML patients, and patients well tolerated. This CLAT protocol offers an alternative treatment for R-AML patients who received severe intensive treatment, especially with anthracycline-containing chemotherapy.
