Objective To establish a three-dimensional(3-D)structural mode-based nursing quality evaluation index system for the bleeding risk care in patients with deep venous thrombosis(DVT)of lower extremity receiving catheter-directed thrombolysis(CDT),so as to provide a reference for the normalization and standardization of bleeding risk care.Methods Based on the 3-D structural mode,through literature review,clinical practice research and group discussion,the first draft of nursing quality evaluation index system for CDT bleeding risk care was formulated.Using Delphi method,two rounds of letter inquiry were conducted,and the index content and index weighting were determined.Results The nursing quality evaluation index system included 3 level-Ⅰ indicators,11 level-Ⅱ indicators and 58 level-Ⅲ indicators.Two rounds of expert consultation were conducted,with 30 questionnaires for each round.The valid recovery rate of the questionnaire was 100.00％,indicating that expert's enthusiasm was higher.In the first round of letter inquiry,28 experts(93.3％)submitted suggestions for modification,and in the second round of letter inquiry,15 experts(50.0％)submitted suggestions for draft modification.The level of expert authority was as follows:the basis coefficient of expert judgment(Ca)was 0.93,the coefficient of expert familiarity with items(Cs)was 0.90,and the authority coefficient was 0.92.The degree of expert opinion coordination assessed by Kendall's harmony coefficient(Kendall's W)was 0.18-0.26(P＜0.05),and the coefficient of variation of each dimension was less than 0.15.Conclusion The nursing quality evaluation index system established in this study is scientific,reliable and practical.It can provide certain useful reference for the evaluation of CDT bleeding risk care quality.

Creutzfeldt-Jakob disease(CJD)is a rapidly progressive and fatal neurodegenerative disorder caused by prions,with certain infectivity and iatrogenic transmission risks.With the rapid progress and application of new dia-gnostic biomarkers and detection methods,as well as the construction and improvement of surveillance and reporting systems,the detection of CJD in patients domestically and internationally has shown an increasing trend year by year.Due to its long incubation period and heterogeneity of early symptoms,early identification and diagnosis of the disease is difficult,increasing the risk of transmission within medical institutions.Currently,there is a lack of con-sensus on the infection prevention and control of CJD.In order to timely identify and diagnose CJD as well as effec-tively block its transmission in medical institutions,this consensus summarizes 15 clinical concerns and formulates 24 specific recommendations based on the latest domestic and international research findings and clinical evidence,as well as combines with clinical practice,aiming to standardize healthcare-associated infection prevention and control measures for CJD and reduce its transmission risk in medical institutions.

Objective:To explore the efficacy of a bleeding risk graded management program in patients with lower extremity deep vein thrombosis (DVT) undergoing catheter-directed thrombosis (CDT) .Methods:Convenience sampling was used to select 100 DVT patients who underwent CDT from October 2021 to December 2023 in the Nanjing First Hospital as study subjects. According to the propensity matching score ratio of 1: 1, patients were divided into control group and observation group, with 50 cases in each group. Control group implemented CDT routine nursing and rehabilitation exercises, and observation group implemented a bleeding risk graded management program based on control group by dynamically monitoring changes in plasma fibrinogen and blood pressure. Differences in the rates of swelling reduction in the limbs, venous patency, bleeding events and hospitalization satisfaction were compared between the two groups.Results:After the intervention, the swelling reduction rate of the limbs of DVT patients in observation group was (85.07±11.96) %, and the rate of venous patency was (89.00±25.33) %, and that of control group was (70.85±21.73) %, (75.00±35.36) %, and the differences were statistically significant (all P<0.05). The rate of bleeding events was lower in the observation group than in the control group, and the difference was statistically significant ( P<0.05). The difference in hospitalization satisfaction between the two groups was not statistically significant ( P>0.05) . Conclusions:The bleeding risk graded management program developed after comprehensive assessment can realize the balance between the therapeutic benefit and bleeding risk of CDT for DVT patients, and can improve the safety and effectiveness of CDT.

Objective To discuss the clinical effect of biomimetic salivary gland induction technology in alleviating secondary xerostomia after endovascular intervention of isolated superior mesenteric artery dissection(ISMAD).Methods Using random number sampling method,a total of 80 patients with ISMAD,who received endovascular intervention at the Affiliated Nanjing Hospital of Nanjing Medical University of China between March 2020 and December 2022,were selected as the research subjects.For the patients of control group(n=40)the warm-water(25-35 ℃)cotton swab was adopted to moisten the lips from one hour to 48 hours after endovascular intervention,which was given once every 15 minutes within postoperative 1-2 hours,which was followed by once every 30 minutes within postoperative 3-48 hours.For the patients of study group(n=40)with the help of biomimetic salivary gland induction technology a continuous and controlled water flow at a rate of 15 mL/h was given from one hour to 48 hours after endovascular intervention to continuously keep the lips and mouth moist.The postoperative one-,12-,24-and 48-hour degrees of mouth dryness and oral comfort in both groups were analyzed.Results The postoperative one-,12-,24-,and 48-hour incidence of thirsty and the degrees of severity in the study group were significantly lower than those in the control group(all P＜0.01),and the degrees of oral comfort at postoperative different time points in the study group were remarkably better than those in the control group(all P＜0.01).Conclusion The use of biomimetic salivary gland induction technology in patients with ISMAD after receiving endovascular intervention therapy can significantly reduce the incidence and severity of thirsty and improve oral comfort.

Objective:To summarize and analyze the current application status of oral mucosal graft (OMG) technique in the repair of ureteral strictures in China, and clarify the feasibility, safety and effectiveness of this technique.Methods:The 175 patients who underwent repair of ureteral stricture using oral mucosal patches from June 2015 to February 2022 were etrospectively analyzed in 14 medical centers in China, including 49 cases in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, 32 cases in Affiliated Seventh Medical Center of PLA General Hospital, 3 cases in The Second Hospital of Anhui Medical University, 6 cases in The First Affiliated Hospital of Zhengzhou University, 56 cases in Peking University First Hospital, 3 cases in Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, 3 cases in Shanghai Sixth People' s Hospital, 4 cases in General Hospital of Estern Theater Command, 4 cases in Lanzhou University Second Hospital, 2 cases in Guizhou Province People 's Hospital, 2 cases in Peking University People' s Hospital, 5 cases in Jinzhou First People's Hospital, 5 cases in The First Affiliated Hospital of Wannan Medical College, 1 case in Shandong Provincial Hospital. In this study, 127 patients (72.6%) used lingual mucosal patches, 32(18.3%) labial mucosa, and 16(9.1%) buccal mucosa. The surgical approach for OMG ureteral reconstruction was mainly minimally invasive, with robot-assisted laparoscopy in 84 patients (48.0%), traditional laparoscopic surgery in 87 patients (49.7%), and open surgery in only 4 patients (2.3%). There were 133 males and 42 females with an average age of (35.0±17.2) years. The mean body mass index (BMI) and stenosis length were (23.1±4.1) kg/m 2 and (4.7±1.8) cm, respectively. The stricture was located in the left ureter in 116 patients, right ureter in 58 case and bilateral ureter in 1 case. The most common causes of ureteral stricture were endoscopic surgery in 88(50.3%)patients, congenital stricture in 55(31.4%)patients, failed ureteroplasty in 29(16.6%)patients, history of extracorporeal shock wave lithotripsy in 13(7.4%)patients, radiotherapy history in 3(1.7%)patients and other causes in 6(3.4%)patients. Strictures were mainly located in the upper ureter, accounting for 61.7% (108/175 cases), followed by 36.0% (63/175) at the ureteropelvic junction and 2.3%(4/175)in the middle ureter. According to the surgical methods, the patients were divided into robot-assisted laparoscopic surgery group ( n=84), traditional laparoscopic surgery group ( n=87)and open surgery group ( n=4). Subgroup analysis of patients in robot-assisted laparoscopic and traditional laparoscopic surgery groups was performed. There were no significant difference in preoperative data between the two groups except for age (32.0±18.3) years vs.(37.0±15.9)years, P=0.040], BMI[(22.5±4.3)kg/m 2 vs. (23.7±3.6)kg/m 2, P=0.028], and etiology of stenosis [endoscopic injury, 34(40.5%) vs. 53(60.9%), P=0.012]. Preoperative hydronephrosis and stricture length were assessed by CTU and ureterography. Ureterography 7-9 weeks after surgery showed patency of the reconstructed segment, or no recurrence of hydronephrosis was judged as success. Evaluate the operation method, operation time, success rate, length of OMG in repairing ureteral stricture between laparoscopic and robot-assisted groups. Results:The overall success rate of oral mucosal graft repair surgery reached 97.7%(171/175). The success rate of ureteral reconstruction in the two groups were 96.4%(81/84)and 98.9%(86/87), respectively ( P=0.351), and the difference was not statistically significant. There was no significant difference for operation time, intraoperative blood loss, and mean oral mucosal length between the robotic and laparoscopic groups[(244.7±85.8) min and (222.7±83.5)min ( P=0.116), (58.9±38.6) ml and (68.4±45.5) ml ( P=0.217), (5.0±2.0) cm and (4.6±1.5) cm ( P=0.350)], respectively.Postoperative complications were reported in 23 (13.1%) patients, such as fever, urinary leakage, lymphatic leakage, infection, but only 2 (1.4%) cases patients had complications of Clavien-Dindo score &ge; Ⅲ. The two patients developed urinary stricture after surgery with failed conservative treatment, and no urinary stricture occurred following endoscopic treatment.The short-term (three months after surgery)incidence of complications in the site where the oral mucosa was taken, such as difficulty in opening mouth, pain, and swelling, was 12.0% (21/175), and there was no significant difference for oral complications between patients harvesting different length of mucosal graft. Conclusions:Ureteroplasty with oral mucosal graft is a safe, feasible and reliable technique for ureteral reconstruction. At present, minimally invasive technology is the main surgical approach for ureteroplasty, and there is no significant difference in operation time and success rate between robotic surgery and laparoscopic surgery.

The dental operative microscope has been widely employed in the field of dentistry, particularly in endodontics and operative dentistry, resulting in significant advancements in the effectiveness of root canal therapy, endodontic surgery, and dental restoration. However, the improper use of this microscope continues to be common in clinical settings, primarily due to operators' insufficient understanding and proficiency in both the features and established operating procedures of this equipment. In October 2019, Professor Jingping Liang, Vice Chairman of the Society of Cariology and Endodontology, Chinese Stomatological Association, organized a consensus meeting with Chinese experts in endodontics and operative dentistry. The objective of this meeting was to establish a standard operation procedure for the dental operative microscope. Subsequently, a consensus was reached and officially issued. Over the span of about four years, the content of this consensus has been further developed and improved through practical experience.
