Objective:To summarize the clinicopathological features, evolving trends in treatment and surgical approaches, and survival outcomes of patients who underwent D2 radical gastrectomy for gastric cancer in Shanxi Provincial Cancer Hospital over the past 11 years with the goal of providing a reference for the clinical practice of gastric cancer in this region.Methods:A retrospective observational study was conducted to analyze the clinicopathological data of patients who underwent D2 radical gastrectomy for pathologically confirmed gastric malignancy at the Department of Gastrointestinal Surgery, Shanxi Provincial Cancer Hospital from January, 2013 to December, 2023. Exclusion criteria consisted of: (1) residual gastric cancer or recurrent gastric cancer after surgery; (2) emergency gastric cancer resection due to bleeding, perforation, obstruction, or other causes; (3) comorbidity with other primary malignant tumors; (4) severe preoperative cardiopulmonary insufficiency or hepatic and renal insufficiency who cannot tolerate radical surgery; and (5) inconsistent main diagnosis information across the medical record system, pathological system, and gastric cancer-specific database. Patients were divided into three groups based on treatment methods: the surgery-only group, the perioperative chemotherapy group, and the adjuvant chemotherapy group. Endpoints included: (1) baseline patient characteristics; (2) trends in tumor location and pathological features; (3) evolution of treatment modalities; and (4) survival outcomes.Results:A total of 15,644 patients were included in the analysis, with 12,591 males and 3,053 females, the male-to-female gender ration was approximately 4∶1; the mean age was (61.2±9.5) years. The tumor sites were mainly concentrated in the esophagogastric junction (EGJ) (57.4%), followed by the antrum (25.9%). The incidence of EGJ cancer initially rose and then declined. However, gastric antrum tumors remained stable, and gastric body tumors showed a slow upward trend after 2020, accounting for 16.7%. In terms of pathological types, poorly differentiated carcinoma was the most prevalent, accounting for 55.9%, followed by moderately differentiated carcinoma (24.2%), mucinous adenocarcinoma (or signet ring cell carcinoma,14.1%), neuroendocrine carcinoma (4.8%), and well-differentiated carcinoma (0.9%). The proportion of poorly differentiated adenocarcinoma showed a significant upward trend overall as well, peaking at 65.6% in 2022 and decreasing to 57.5% in 2023. Mucinous adenocarcinoma (or signet ring cell carcinoma) exhibited fluctuations with a first increase followed by a decrease: it peaked at 17.3% in 2018, dropped sharply to 8.4% in 2022, and rose back to 13.8% in 2023. The proportions of well-differentiated adenocarcinoma, moderately differentiated adenocarcinoma, and neuroendocrine tumors remained stable year by year. In terms of pathological staging, the overall proportions of gastric cancer at Stage 0, Stage I, Stage II, Stage III, and Stage IVa were 0.5%, 17.3%, 25.1%, 54.9%, and 2.3%, respectively. For Stage III, its proportion was 74.6% in 2013, which decreased to 46.4% by 2023. Stages I and II gastric cancer showed an upward trend, with their proportions rising from 10.2% and 12.1% in 2013 to nearly 21.0% and 29.6% in 2023, respectively. Between 2013 and 2023, the proportion of patients who received surgery alone continued to decrease, with this proportion dropping to 34.7% in 2023. In contrast, the number of patients who received adjuvant chemotherapy increased year by year, reaching 54.2% in 2023. Since 2017, the application of perioperative chemotherapy has gradually increased, rising to 11.1% in 2023. Immunotherapy showed an almost synchronous growth trend with perioperative chemotherapy. However, targeted therapy exhibited a downward trend after a period of growth. There were 10,704 cases of open surgery (68.4%), 4,744 cases of laparoscopic surgery (30.3%), and 193 cases of transthoracic surgery (1.2%). Pathological margin positivity was observed in 443 cases (2.8%), and the volume of gastric cancer surgeries gradually increased, peaked in 2021 before subsequently decreasing gradually. However, the volume of laparoscopic surgeries did not decrease; instead, it showed an upward trend. The main resection method for EGJ tumors was total gastrectomy, accounting for 78.5% of the total, followed by proximal gastrectomy, which accounted for 21.5%. After total gastrectomy, esophagojejunal Roux-en-Y anastomosis was the primary anastomotic method, and for proximal gastrectomy, the main anastomotic method was esophagogastric anastomosis, which accounted for 68.0% of the total. For distal gastrectomy, Billroth II anastomosis was the most common anastomotic technique, accounting for 92.7% of these procedures. The overall incidence of postoperative complications was 14.5% (2,264/15,644), among which the incidence of severe complications (grades III-IV) was 4.5% (706/15,644). The entire cohort was followed up with for (47.1±36.8) months, and the 1-year, 3-year, and 5-year overall survival rates were 86.4%, 65.9%, and 58.1%, respectively. For patients with stage 0, I, II, III, and IV gastric adenocarcinoma, the 1-year overall survival rates were 95.7%, 98.0%, 89.4%, 81.0%, and 49.1%, respectively; the 3-year overall survival rates were 92.1%, 94.6%, 81.9%, 51.4%, and 14.7%, respectively; and the 5-year overall survival rates were 89.4%, 91.7%, 75.1%, 41.5%, and 10.0%, respectively. For patients with stage I, II, III, and IV gastric neuroendocrine carcinoma, the 1-year overall survival rates were 96.7%, 91.1%, 73.8%, and 52.6%, respectively; the 3-year overall survival rates were 87.2%, 69.6%, 46.1%, and 32.1%, respectively; and the 5-year overall survival rates were 87.2%, 62.2%, 36.7%, and 32.1%, respectively.Conclusions:Gastric cancer in Shanxi Province is characterized by a male predominance, a high prevalence of tumors at the esophagogastric junction, a large proportion of poorly differentiated adenocarcinoma, and presentation at advanced stages (predominantly Stage III). The detection rate of early gastric cancer has been increasing year by year, the volume of laparoscopic surgeries has been on the rise annually, and the treatment model has shifted from single surgery to comprehensive treatment.

Objective:To study the clinical efficacy of 3D total hip arthroplasty in elderly patients with acetabular fracture.Methods:A total of 43 patients with non-obsolete acetabular fractures admitted to Xining First People's Hospital from May 2016 to December 2018 were randomly divided into the control group (22 cases) and the observation group (21 cases) for a perspective study. The control group received routine surgery and the observation group was treated with total hip arthroplasty combined with 3D printing. The patient's operation time, intraoperative blood loss, and hospitalization time were recorded. The hip function was assessed by Harris Hip Scale (HHS) after 6 months of follow-up. The patient's quality of life was assessed using the short form 36 item health survey questionnaire (SF-36) before and 6 months after surgery. The complications of the patients during operation and follow-up were recorded.Results:The operation time, hospital stay and intraoperative blood loss were significantly lower in the observation group than those in the control group ( P<0.05). At 6 months after operation, the hip joint function of the observation group was significantly better than that of the control group ( P<0.05); the quality of life scores were significantly higher than the control group ( P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups ( P<0.05). Conclusions:3D printed total hip arthroplasty can effectively improve the operation and hip function of elderly patients with non-obsolete acetabular fracture and the quality of life of patients without increasing adverse reactions.

Objective To investigate the current situation and existing problems of community chronic disease management in China and provide a theoretical basis for community chronic disease management to reduce the mortality and economic burden.

Hot topics are community health services, health management, diabetes and hypertension management, influencing factors. Conclusion Community chronic disease management has drawn a lot of attention in China. Economically well-developed provinces invested more on community chronic disease management. Universities are the main research institutions. Most researches are still at the exploratory stage.

Objective:To compare the prognosis of hemodialysis (HD) and peritoneal dialysis (PD) in end-stage renal disease (ESRD) patients without diabetes mellitus and identify related influencing factors.Methods:Patients who started hemodialysis with an arteriovenous graft or fistula or PD in the First Affiliated Hospital of Zhengzhou University from January 1, 2013 to February 1,2019 were included. They were followed up until May 1, 2019. The patients were divided into HD group and PD group according to the initial dialysis modality. Kaplan-Meier method was used to obtain survival curves, the Cox regression model was used to evaluate influence factors for survival rates, and the inverse probability of treatment weighting (IPTW) was used to eliminate influence of the confounders in the groups.Results:There were 371 patients with maintenance dialysis enrolled in this study, including 113 cases (30.5%) in HD group and 258 cases (69.5%) in PD group. At baseline, the scores of standard mean difference ( SMD) in age, body mass index (BMI), combined with cerebrovascular disease, Charlson comorbidity index (CCI), blood potassium, plasma albumin and hemoglobin between the two groups were greater than 0.1. The score of SMD decreased after IPTW, and the most data were less than 0.1, which meant that the balance had been reached between the two groups. The Kaplan-Meier survival curve showed that the cumulative survival rates had no significant difference for all-cause death before using IPTW between the two groups (Log-rank χ2=0.094, P=0.759). After adjusting for confounders with IPTW, the Kaplan-Meier survival curve showed that the cumulative survival rates still had no significant difference for all-cause death between the two groups (Log-rank χ2=2.090, P=0.150). Univariate Cox regression analysis showed that there was no significant difference between HD and PD on survival rates in ESRD patients without diabetes mellitus for all-cause death (PD/HD, HR=1.171, 95% CI 0.426-3.223, P=0.760). Multivariate Cox regression analysis showed that there was no significant difference between HD and PD on survival rates in ESRD patients without diabetes mellitus (PD/HD, HR=1.460, 95% CI 0.515-4.144, P=0.477), and high plasma albumin ( HR=0.893, 95% CI 0.813-0.981, P=0.019) was an independent protective factor for survival in ESRD patients without diabetes mellitus. There was still no significant difference between HD and PD on survival rates in ESRD patients without diabetes mellitus after using IPTW (PD/HD, HR=1.842, 95% CI 0.514-6.604, P=0.348). Conclusion:The difference of cumulative survival rates between HD and PD is not significant in ESRD patients without diabetes mellitus.

Objective:To study the relationship between IL-1β and TNFα expression and cell apoptosis in gingival tissue of the subjects with diabetes associated periodontitis(DAP).Methods:20 cases of DAP(group DAP) and 20 cases of health controls(group H)were included.The cell apoptosis and the ultrastructural changes in gingival tissue were observed by Tunnel staining and transmission electron microscope (TEM).IL-1β and TNFα expression in gingival tissue were detected by immunohistochemical staining.SBI,GI,PD and AL of the subjects were measured.The relationship between the level of IL-1β,TNFα and the cell appotosis was analyzed.Results:Apoptosis was obvious in prickle cells and basal cells of gingival tissue of DAP group.The percentage of apoptosis cells of DAP group was significantly higher than that of group H(P＜0.01).The expression of IL-1β and TNFα in group DAP was significant higher than that of group H (P＜0.01),and the mainly positive expression cells were macrophages,plasmocytes and lymphocytes.Conclusion:IL-1β and TNFα play a role in cell apoptosis in the gingival tissue of the patients with DAP.

Objective To investigate the effect of formative assessment on skill acquisition of basic life support (BLS) among medical students. Methods Totally 206 undergraduates were ran-domized into control group (C group) and interventional group (F group). A BLS lecture was given in both groups. And then, 45 min BLS training and BLS skill assessment (after training) were given in C group. Undergraduates in F group received BLS skill assessment (formative assessment) before training, and 15 min feedback was delivered based on the assessment, then 30 min BLS training was conducted. Skills assessment was conducted again in F group after the training. Student's-t-test was used to compare the difference of skills between the two groups and P<0.05 signifies statistically sig-nificant differences. Results Score of F group (85.2±7.3) were higher than that in C group (68.2± 13.2), with statistical difference. Conclusion A formative assessment could significantly improve skill acquisition of BLS among medical students.
