Objective:To investigate the influencing factors and prognosis of early recurrence after gastrectomy for gastric cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 2 078 patients who underwent gastrectomy for gastric cancer at six medical centers across China, including Fudan University Shanghai Cancer Center et al, between January 2012 and June 2023 were collected. There were 1 449 males and 629 females, aged (59±11) years. Patients were classified as early recurrence and late recurrence based on the time of post-operative recurrence. Observation indicators: (1) comparison of clinicopathological characteristics between gastric cancer patients with different recurrence types; (2) recurrence and metastasis of tumor; (3) survival of patients after postoperative recurrence of gastric cancer; (4) analysis of influencing factors for early recurrence after gastrectomy for gastric cancer. Comparison of measurement data with normal distribution between groups was conducted using the independent sample t test. Comparison of measurement data with skewed distribution between groups was conducted using the Mann-Whitney U test. Comparison of count data between groups was conducted using the chi-square test. Comparison of ordinal data between groups was conducted using the rank sum test. Multivariate analysis was conducted using the Logistic regression model. Kaplan-Meier method was used to calculate survival rate and plot survival curve, and Log-rank test was used for survival analysis. Results:(1) Comparison of clinicopathological characteristics between gastric cancer patients with different recurrence types. Among the 2 078 patients, 1 452 cases had early recurrence and 626 cases had late recurrence. There were significant differences in preoperative carcinoembryonic antigen, preoperative CA19-9, preoperative CA72-4, preoperative albumin, tumor diameter, neoadjuvant therapy, R 0 resection, combined organ resection, scope of gastric resection, nerve and vessel infiltration, degree of tumor differentiation, pathological N staging, pathological TNM staging between early and late recurrence patients ( P<0.05). (2) Recurrence and metastasis of tumor. Among the 2 078 patients, 200 cases had local recurrence, 1 213 cases had hematogenous metastases, 392 cases had distant lymph node metastases, and 731 cases had peritoneal metastases. Among the 1 452 early recurrence patients, 142 cases had local recurrence, 834 cases had hematogenous metastases, 289 cases had distant lymph node metastases, and 507 cases had peritoneal metastases. Among the 626 late recurrence patients, 58 cases had local recurrence, 379 cases had hematogenous metastases, 103 cases had distant lymph node metastases, and 224 cases had peritoneal metastases. One patient may have multiple forms of recurrence and metastasis. There was no significant difference in the above indica-tors between early and late recurrence patients ( χ2=0.13, 1.74, 3.40, 0.14, P>0.05). (3) Survival of patients after postoperative recurrence of gastric cancer. All 2 078 patients were followed up until death after recurrence, with a follow-up time of 31(range, 9?147)months. The 1-, 2-, 3-, and 5-year overall survival rates after recurrence were 33.5%, 17.2%, 10.1%, and 3.3% in early recurrence patients, versus 44.2%, 21.6%, 12.8%, and 5.8% in late recurrence patients, respectively, showing a significant difference in overall survival after recurrence between the two groups ( hazard ratio=0.84, 95% confidence interval as 0.76?0.92, P<0.05). (4) Analysis of influencing factors for early recurrence after gastrectomy for gastric cancer. Results of multivariate analysis showed that combined organ resection, total gastrectomy, pathological TNM staging as stage Ⅲ were independent risk factors for early recurrence after gastrectomy for gastric cancer ( odds ratio=1.31, 1.32, 1.34, 95% confidence interval as 1.01?1.70, 1.06?1.65, 1.05?1.71, P<0.05) and normal preoperative tumor markers, neoadjuvant therapy, R 0 resection were independent protective factors for early recurrence ( odds ratio=0.61, 0.50, 0.38, 95% confidence interval as 0.49?0.76, 0.35?0.72, 0.25?0.58, P<0.05). Conclusions:Compared with patients with late recurrence after gastric cancer surgery, patients with early recurrence have a poor prognosis, in which liver metastases is more common. Combine organ resection, total gastrectomy, pathological TNM staging as stage Ⅲ are independent risk factors for early recurrence, and normal preoperative tumor markers, neoadjuvant therapy, R 0 resection are independent protective factors for early recurrence after gastrectomy for gastric cancer.

Objective:To investigate the clinical efficacy of extended abdominal wall resec-tion combined with reconstruction for abdominal wall aggressive fibromatosis (AF).Methods:The retrospective and descriptive study was conducted. The clinical data of 70 patients with abdominal wall AF who were admitted to 3 medical centers, including The First Affiliated Hospital of the University of Science and Technology of China, between January 2009 and July 2024 were collected. There were 6 males and 64 females, aged (36±13)years. All patients underwent extended abdominal wall resection combined with abdominal wall reconstruction. Observation indicators: (1) surgical situations; (2) tumor recurrence and postoperative complications. Comparisons of measurement data with skewed distribution between groups was conducted using the Mann-Whitney U test. Comparison of count data between groups was conducted using the chi-square test. Results:(1)Surgical situations. All 70 patients underwent extended abdominal wall resection combined with abdominal wall recons-truction. The operation time was 90(91)minutes and duration of postoperative hospital stay was 10(6)days. Of the 70 patients, 41 patients underwent abdominal wall AF resection plus polypropylene mesh abdominal wall reconstruction, with a defect area of 60(54)cm2. The mesh placement method was uniformly Sublay repair. The remaining 29 patients underwent abdominal wall AF resection plus direct suture repair, with a defect area of 34(31)cm2. There was a significant difference in the abdominal wall defect area between the two groups ( U=291.00, P<0.05). All 70 patients achieved R 0 resection. The distance from surgical margin to tumor edge was 2-3 cm in 39 cases and >3 cm in 31 cases. (2) Tumor recurrence and postoperative complications. All 70 patients were followed up for 78(90)months. During follow-up, 10 patients developed tumor recurrence (5 cases with mesh reinforced abdominal wall reconstruction and 5 cases with direct suture repair). Among them, one case was monitored, one case underwent radiotherapy, and neither received further surgical treatment. The remaining 8 patients underwent repeat R 0 resection, and no further recurrence occurred. There was no significant difference in recurrence rate between the patients with mesh reconstruction and patients with direct suture repair ( χ2=0.06, P>0.05). The postoperative recurrence rate was 9.7%(3/31) in patients with the distance from surgical margin to tumor edge >3 cm, versus 17.9%(7/39) in patients with the distance from surgical margin to tumor edge of 2-3 cm, showing no significant difference between them ( χ2=0.97, P>0.05). Sixty patients had no tumor recurrence. During follow-up, none of the 70 patients developed incisional hernia. Two patients experienced postoperative wound infection, and 6 cases developed postoperative chronic pain. Conclusion:Extended abdominal wall resection combined with reconstruction is safe and feasible for abdominal wall AF.

Hypertension is a major factor leading to cardiovascular events and death, and accurate blood pressure measurement is a fundamental means of evaluating blood pressure levels, achieving hypertension diagnosis, and observing antihypertensive efficacy. Compared to traditional brachial pressure, central aortic pressure (CAP) exhibits a stronger correlation with cardiovascular events. However, its non-invasive detection technology has not yet been widely adopted in clinical practice. In order to promote the clinical application of CAP and optimize blood pressure management, this article systematically summarizes the research progress of CAP estimation algorithms. These algorithms were categorized into three types: direct substitution methods, generalized model-based methods and personalized estimation methods. The characteristics and clinical adaptability of each algorithm were analyzed. The findings highlight that CAP estimation algorithms are moving towards personalization and non-linearity.

Objective:To evaluate the mid-term efficacy of sleeve gastrectomy combined with single anastomosis gastric-ileal bypass (SASI) for treating gastroesophageal reflux disease (GERD) after laparoscopic sleeve gastrectomy (LSG).Methods:Clinical data of 10 patients with post-LSG GERD undergoing SASI at the Department of Hernia and Bariatric Surgery, the First Affiliated Hospital of University of Science and Technology of China between Jan 2022 and Oct 2024 was retrospectively analyzed. Surgical safety and mid-term outcomes were evaluated.Results:The mean follow-up period was (25.40±17.33) months. The GerdQ score significantly decreased from (14.00±2.05) preoperatively to (5.70±1.49) postoperatively ( t=10.330, P<0.001), with a GERD remission rate of 90 % (9/10). Postoperative body weight and body mass index (BMI) both showed statistically significant reductions compared to preoperative values. Weight dropped from (110.29±22.92) kg to (84.95±15.89) kg ( t=5.889, P<0.001), and BMI decreased from (38.98±7.16) kg/m2 to (30.02±4.88) kg/m2 ( t=6.086, P<0.001). The percentage of excess weight loss was 65.88%±32.85%, and the percentage of total weight loss was 22.43%±9.65%. Only one patient experienced transient postoperative diarrhea, which resolved spontaneously, and no severe malnutrition cases were observed. Conclusion:SASI effectively improves GERD symptoms after LSG with favorable safety, serving as a suitable revisional surgical option for those patients.

Objective:To explore the safety and effectiveness of laparoscopic treatment for complicated appendicitis in children with and without abscess.Methods:A retrospective analysis was conducted on the clinical data of 363 patients with complicated appendicitis admitted to our department between May 2017 and Sep 2023. Patients were divided into two groups: the group without abscess and the group with abscess, comparing the surgical outcomes and incidence of postoperative complications between two groups.Results:As a result, all 277 cases in the non abscess group completed laparoscopic appendectomy, while all 86 cases in the periappendibular abscess group also completed laparoscopic appendectomy. The history of appendiceal abscess group was longer than that of the group without abscess [5(3-7) d vs. 2(1-3) d, Z=-11.59, P<0.05],the operation time was longer [86 (68-121) min vs. 63 (50-76) min, Z=-7.260, P<0.05], intraoperative bleeding was more [5(3-10) ml vs. 2(2-5) ml, Z=-7.010, P<0.001]. The incidence of postoperative complications was higher in the appendiceal abscess group, with a postoperative abdominal abscess rate of 11.1%,compared to 6.9% ( χ2=1.656, P=0.198), and the incision infection rate of 4.9%,compared to 4.0% ( χ2=0.008, P=0.930), the intestinal obstruction rate was 4.9%,compared to 3.2%, ( χ2=0.158, P=0.691), the intestinal injury rate was 1.3% ,compared to 0,( P=0.226). Conclusions:Laparoscopic appendectomy for periappendiceal abscess in children was safe and effective, especially for patients with a medical history of less than 7 d.

OBJECTIVES: This study aimed to investigate the perception of dental outpatient care quality from multiple perspectives of administrators, physicians, nurses, and patients and propose nursing care quality evaluation indices that are consistent with the clinical reality to provide reference for the construction of a scientific, systematic, and comprehensive dental outpatient care quality evaluation system. METHODS: A total of 39 interviewees, including 7 administrators, 11 doctors, 11 nurses, and 10 patients, were selected for semi-structured in-depth interviews in five regionally representative tertiary-level A stomatological specialty hospitals nationwide during January-April 2024 by using a multistage sampling method. Colaizzi 7-step analysis was used to analyze and summarize the interview data. Themes were extracted on the basis of the Structure-Process-Outcome (SPO) three-dimensional quality assessment model. RESULTS: Five main themes and 15 secondary themes were extracted from three quality dimensions: structure, process, and result. The related topics of structural quality were as follows: disinfection and isolation norms, equipment and consumable management, nursing manpower ratio and nurse education structure, and emergency capability. The related topics of process quality were as follows: pre-diagnosis risk assessment, patient triage and guidance, communication and attitude, health education, humanistic care, continuous care, specialty operation, and four-hand operation. The related topics of result quality were as follows: satisfaction, adverse event management and analysis, effective complaints and disputes. CONCLUSIONS Structure quality is the foundation, process quality is the core, and result quality is the key in the evaluation of the quality of oral outpatient care. The standardization of disinfection and isolation, equipment and consumable management, allocation of reasonable nursing manpower and post capacity, implementation of high-quality nursing services, and improvement of the quality and satisfaction of medical cooperation are necessary guarantees to ensure the quality of oral outpatient care.
