Objective To explore the application of evidence-based nursing based on mind mapping in patients undergoing knee arthroscopic surgery.Methods Ninety patients who underwent arthroscopic surgery in Dongzhimen Hospital,Beijing University of Chinese Medicine from June 2021 to January 2023 were selected for prospective study.They were randomly assigned to study group or control group according to the random number table,with 45 cases in each group.The control group was given routine nursing,and the study group was given evidence-based nursing based on mind mapping.The nursing care continued until one month after discharge.Psychological resilience score,pain degree[(visual analogue scale,VAS)score],hospitalization time,hospital knee score(HSS)score,postoperative complications and satisfaction degree at discharge were compared between the two groups.Results Repeated measures showed that there were significant differences in the time-point effect,intergroup effect and interaction effect of psychological resilience score and HSS score between the two groups(P<0.05),and the psychological resilience score and HSS score of the study group were higher than those of the control group(P<0.05).The VAS score at discharge and hospital stay of the study group were superior to those of the control group(P<0.05).The incidence of postoperative complications in the study group was lower than that in the control group(2.22%vs 17.78%,P<0.05).The degree of patients'satisfaction in the study group was higher than that in the control group(P<0.05).Conclusion Evidence-based nursing based on mind mapping can effectively improve psychological resilience,relieve postoperative pain,increase the range of motion of the knee,promote recovery,reduce postoperative complications and improve clinical satisfaction.

Objective:To investigate the effects of Clostridium butyricum on ulcerative colitis（UC）in mice and its impact on gut microbiota and autophagy levels. Methods:Eighteen C57BL/6J mice were randomly divided into a control group，a model group，and a treatment group，with six mice in each group using simple random sampling. Mice in the model and treatment groups were freely given 2.5% dextran sulfate sodium salt（DSS）solution for 5 days to establish a UC model. After successful modeling，the control and model groups were gavaged with PBS，while the treatment group was gavaged with 5×10 8 CFU/ml of live Clostridium butyricum. After the intervention，changes in body weight，disease activity index（DAI），colonic length，and pathological conditions were compared among the groups. Fluorescence quantitative PCR was used to detect the expression levels of intestinal inflammatory cytokines IL-1β and TNF-α. Myeloperoxidase（MPO）levels were analyzed，and Western blot was employed to detect the expression levels of zonula occludens-1（ZO-1），Occludin，LC3Ⅱ/LC3I，p62，and AMP-activated protein kinase/mammalian target of rapamycin AMPK/mTOR proteins. High-throughput sequencing technology was utilized to analyze the intestinal microbiota of the mice. Results:Compared with mice in the control group，the mice in the model group exhibited significant weight loss，markedly increased DAI and inflammation levels（ P<0.01），destruction of colonic structure，decreased expression levels of intestinal tight junction proteins（ P<0.05），suppressed autophagy levels（ P<0.05），and dysbiosis of the intestinal microbiota. In contrast，mice in the treatment group had a slower weight decline compared to the model group（ P<0.000 1），reduced DAI（ P<0.01），down-regulated inflammation levels（ P<0.01），improved barrier function（ P<0.05），up-regulated autophagy levels（ P<0.01），and an improved intestinal microbiota composition. Conclusions:Clostridium butyricum may ameliorate UC by modulating the intestinal microbiota composition，and enhancing autophagy levels，thus improving intestinal barrier function and inhibiting inflammatory progression in UC mice.

Objective:To investigate the clinical efficacy of fixation with a modified double-pulley anchor suture in the treatment of Rockwood type Ⅱ patella fractures.Methods:A retrospective study was conducted to analyze the 60 patients with Rockwood type Ⅱ patellar fracture who had been admitted to Department of Joint Surgery, The Hospital Affiliated to Qingdao University between November 2021 and November 2023. The cohort included 31 males and 29 females, with an age of (53.5±10.4) years. According to the treatment methods, the patients were divided into a study group (28 cases) which was treated by traction reinforcement of the terminal anchor suture in addition to fixation with a double-pulley anchor suture, and a control group (32 cases) which was treated by the traditional Kirschner wire tension band technique. The operation time, intraoperative blood loss, incision length, reoperation rate, complication rate, fracture healing, and visual analog scale (VAS) pain scores and Bostman scores at postoperative 1 month, 3 months, and 6 months and at the last follow-up were compared between the 2 groups.Results:No statistically significant differences were observed in the preoperative general data between the 2 groups, indicating that the 2 groups were comparable ( P>0.05). All patients were followed up for (12.8±1.4) months postoperatively. The study group demonstrated significantly lower intraoperative blood loss [(25.9±6.8) mL] than the control group [(40.5±11.6) mL], and a significantly lower reoperation rate (0) than the control group [53.1% (17/32)] ( P<0.05). There was no statistically significant difference between the 2 groups in operation time, incision length, incidence of complications, as well as in VAS pain scores or Bostman scores at postoperative 1 month, 3 months, or 6 months or at the last follow-up (all P>0.05). Fractures healed in both groups at 6 months postoperatively. Conclusions:For patients with Rockwood type Ⅱ patellar fracture, fixation with modified double-pulley suture anchor can achieve good clinical efficacy. Compared to the traditional Kirschner wire tension band technique, the modified mothed significantly reduces intraoperative blood loss and avoids secondary trauma caused by a second surgery for implant removal.

Objective:To explore the effectiveness of the"full-chain"integrated medical and elderly care service model in addressing key issues in medical-nursing services such as weak medical support capacity and insufficient provision of community-and home-based medical-nursing services.Methods:The development pathway for the"full-chain"integrated medical-elderly care service standardization system,encompassing core components such as operational mechanisms,smart platforms,policy documents,and quality control systems was systematically outlined.Effectiveness based on dimensions including service coverage,quality improvement,talent development,and social benefits was evaluated.With standardization as the core driver,the'1234567'management model was innovatively implemented.Results:The model leveraged the downward allocation of high-quality resources from tertiary general hospitals to strengthen subdistrict community health service centers.By collaborating with subdistrict elderly-care service centers,it established"subdistrict medical-elderly care and wellness service centers".These centers enhanced the capabilities of"community-embedded elderly-care complexes",including community daytime care centers,established two-way referral channels between medical and elderly care services,aligned with healthcare demands to provide elderly individuals with reliable medical support.It reduced the burden on families and society,stimulated market vitality,boosted domestic demand,promoted the development of integrated medical-elderly care and wellness initiatives,thereby advancing the silver economy.With provincial government endorsement,the model had been applied to 203 communities across 37 counties by the end of 2024.Conclusion:The established"full-chain"integrated medical-elderly care service model facilitates regional high-quality development in integrated care by consolidating healthcare group resources and seamlessly connecting the service chain across hospitals,nursing homes,community institutions,and home-based settings,thereby creating a practical paradigm for comprehensive elderly care service delivery.

The introduction of vitrectomy has solved a difficult and intractable problem in the ophthalmology community for the treatment of fundus oculi diseases. To date, minimally invasive vitrectomy(MIV)is the main surgery for the treatment of fundus oculi diseases. Clinically, patients develop dry eye symptoms after MIV, including lacrimation, foreign body sensation, and visual disturbances. We speculates that MIV may damage the conjunctival and corneal epithelium as well as related sensory nerves, disrupting the tear film and causing a local inflammation response, thereby further affecting the ocular surface microenvironment and inducing or aggravating dry eye symptoms. At present, there are few studies on the changes of ocular surface after MIV. This article aims to analyze the effects of different factors on the microenvironment of the ocular surface before, during and after MIV, and to provide preventive and curative measures that can be taken to guide the clinic to make good preparations for the operation, to choose the appropriate surgical procedure, and to reduce the risk of dry eye in the postoperative period.

Objective:To evaluate the safety of double and a half layered esophagojejunal anastomosis in radical gastrectomy.Methods:This prospective, multi-center, single-arm study was initiated by the Affiliated Cancer Hospital of Zhengzhou University in June 2021 (CRAFT Study, NCT05282563). Participating institutions included Nanyang Central Hospital, Zhumadian Central Hospital, Luoyang Central Hospital, First Affiliated Hospital of Henan Polytechnic University, First Affiliated Hospital of Henan University, Luohe Central Hospital, the People's Hospital of Hebi, First People's Hospital of Shangqiu, Anyang Tumor Hospital, First People's Hospital of Pingdingshan, and Zhengzhou Central Hospital Affiliated to Zhengzhou University. Inclusion criteria were as follows: (1) gastric adenocarcinoma confirmed by preoperative gastroscopy;(2) preoperative imaging assessment indicated that R0 resection was feasible; (3) preoperative assessment showed no contraindications to surgery;(4) esophagojejunostomy planned during the procedure; (5) patients volunteered to participate in this study and gave their written informed consent; (6) ECOG score 0–1; and (7) ASA score I–III. Exclusion criteria were as follows: (1) history of upper abdominal surgery (except laparoscopic cholecystectomy);(2) history of gastric surgery (except endoscopic submucosal dissection and endoscopic mucosal resection); (3) pregnancy or lactation;(4) emergency surgery for gastric cancer-related complications (perforation, hemorrhage, obstruction); (5) other malignant tumors within 5 years or coexisting malignant tumors;(6) arterial embolism within 6 months, such as angina pectoris, myocardial infarction, and cerebrovascular accident; and (7) comorbidities or mental health abnormalities that could affect patients' participation in the study. Patients were eliminated from the study if: (1) radical gastrectomy could not be completed; (2) end-to-side esophagojejunal anastomosis was not performed during the procedure; or (3) esophagojejunal anastomosis reinforcement was not possible. Double and a half layered esophagojejunal anastomosis was performed as follows: (1) Open surgery: the full thickness of the anastomosis is continuously sutured, followed by embedding the seromuscular layer with barbed or 3-0 absorbable sutures. The anastomosis is sutured with an average of six to eight stitches. (2) Laparoscopic surgery: the anastomosis is strengthened by counterclockwise full-layer sutures. Once the anastomosis has been sutured to the right posterior aspect of the anastomosis, the jejunum stump is pulled to the right and the anastomosis turned over to continue to complete reinforcement of the posterior wall. The suture interval is approximately 5 mm. After completing the full-thickness suture, the anastomosis is embedded in the seromuscular layer. Relevant data of patients who had undergone radical gastrectomy in the above 12 centers from June 2021 were collected and analyzed. The primary outcome was safety (e.g., postoperative complications, and treatment). Other studied variables included details of surgery (e.g., surgery time, intraoperative bleeding), postoperative recovery (postoperative time to passing flatus and oral intake, length of hospital stay), and follow-up conditions (quality of life as assessed by Visick scores).Result:[1] From June 2021 to September 2022,457 patients were enrolled, including 355 men and 102 women of median age 60.8±10.1 years and BMI 23.7±3.2 kg/m2. The tumors were located in the upper stomach in 294 patients, mid stomach in 139; and lower stomach in 24. The surgical procedures comprised 48 proximal gastrectomies and 409 total gastrectomies. Neoadjuvant chemotherapy was administered to 85 patients. Other organs were resected in 85 patients. The maximum tumor diameter was 4.3±2.2 cm, number of excised lymph nodes 28.3±15.2, and number of positive lymph nodes five (range one to four. As to pathological stage,83 patients had Stage I disease, 128 Stage II, 237 Stage III, and nine Stage IV. [2] The studied surgery-related variables were as follows: The operation was successfully completed in all patients, 352 via a transabdominal approach, 25 via a transhiatus approach, and 80 via a transthoracoabdominal approach. The whole procedure was performed laparoscopically in 53 patients (11.6%), 189 (41.4%) underwent laparoscopic-assisted surgery, and 215 (47.0%) underwent open surgery. The median intraoperative blood loss was 200 (range, 10–1 350) mL, and the operating time 215.6±66.7 minutes. The anastomotic reinforcement time was 2 (7.3±3.9) minutes for laparoscopic-assisted surgery, 17.6±1.7 minutes for total laparoscopy, and 6.0±1.2 minutes for open surgery. [3] The studied postoperative variables were as follows: The median time to postoperative passage of flatus was 3.1±1.1 days and the postoperative gastrointestinal angiography time 6 (range, 4–13) days. The median time to postoperative oral intake was 7 (range, 2–14) days, and the postoperative hospitalization time 15.8±6.7 days. [4] The safety-related variables were as follows: In total, there were 184 (40.3%) postoperative complications. These comprised esophagojejunal anastomosis complications in 10 patients (2.2%), four (0.9%) being anastomotic leakage (including two cases of subclinical leakage and two of clinical leakage; all resolved with conservative treatment); and six patients (1.3%) with anastomotic stenosis (two who underwent endoscopic balloon dilation 21 and 46 days after surgery, the others improved after a change in diet). There was no anastomotic bleeding. Non-anastomotic complications occurred in 174 patients (38.1%). All patients attended for follow-up at least once, the median follow-up time being 10 (3–18) months. Visick grades were as follows: Class I, 89.1% (407/457); Class II, 7.9% (36/457); Class III, 2.6% (12/457); and Class IV 0.4% (2/457).Conclusion:Double and a half layered esophagojejunal anastomosis in radical gastrectomy is safe and feasible.
