Purpose: Due to the preservation of the entire stomach after endoscopic resection, the occurrence of metachronous gastric cancer (MGC) remains a possibility. In this study, we investigated the incidence and risk factors for MGC in patients with early gastric cancer who underwent endoscopic submucosal dissection (ESD) and successfully eradicatedHelicobacter pylori. Materials and Methods: A retrospective analysis was conducted of 1,191 patients who underwent ESD and successfully eradicated H. pylori at the Affiliated Drum Tower Hospital of Nanjing University. Endoscopic surveillance was performed at 3, 6, and 12 months post-resection, and annually thereafter. MGC was defined as the development of a new cancer at a site other than the primary gastric cancer site, at least 1 year after the initial endoscopic resection. Results: A total of 77 patients were diagnosed with MGC during a median follow-up of 41.5 months. Kaplan-Meier analysis showed a 5-year cumulative incidence of MGC of 9.4% after successful H. pylori eradication. Multivariate analysis of the training set using Cox proportional hazards models identified male sex, severe atrophic gastritis, multiple gastric cancers before H. pylori eradication, and smoking history as independent risk factors for MGC.The nomogram exhibited favorable discrimination, with area under the curves of 0.767 and 0.822 in the training set and 0.724 and 0.745 in the testing set at 3 and 5 years, respectively. Conclusions Patients with gastric cancer who undergo endoscopic resection, even after successful H. pylori eradication, should undergo annual and continuous endoscopic surveillance for MGC.

Objective To explore the influencing factors of physical activity(PA)in overweight and obese children from the individual,family and environment levels.Methods Using a stratified cluster random sampling method,315 children[mean age:9.57±1.45 years;201 boys(63.8%)and 114 girls(36.2%)]were selected from two classes of every grade of one public elementary school in the four main urban districts of Shijiazhuang.Hierarchical linear regression models were employed to ana-lyze the influence of 20 factors on individual,family and environment levels on PA among them.Re-sults Children's age(β=-0.02),sex(βmale=0.12),sedentary time(β=-0.07),ball skills(β=0.12),perceived motor competence(β=0.18),primary caregiver's PA(β=0.17),parental PA support(β=0.10)and home/neighborhood PA environment(β=0.40)were significant factors of their moderate-to-vigorous physical activities(P<0.05).For light physical activity(LPA)and total PA,only sedentary time(βLPA=-0.57,βtotal=-0.52),parental support for children's PA(βLPA=0.15,βtotal=0.16),and home/neighborhood PA environment(βLPA=0.17,βtotal=0.15)were significant predictors(Pall<0.05).Conclusion The influencing factors of PA among overweight and obese children are complex and multidimensional.Elements at the individual,family and environment levels all play significant roles.Therefore,future interventions and policies aimed at promoting PA in this population should take these multifaceted de-terminants into consideration.

Objective:To investigate the effect of goal setting theory-guided health management on disease cognition, compliance with antiviral therapy and self-efficacy of patients with chronic hepatitis B (CHB) so as to provide a theoretical basis for developing clinical nursing plans for patients with CHB.Methods:A quasi-experiment study was conducted, and 60 patients with CHB who were admitted to Anhui Provincial Hospital of Integrated Traditional Chinese and Western Medicine (the Third Affiliated Hospital of Anhui University of Chinese Medicine) from November 2022 to June 2023 were selected as the study subjects by convenience sampling method. They were randomly divided into the observation group and the control group by the envelope method, with 30 cases in each group. The control group received routine health management, and the observation group received goal setting theory-guided health management. Effects on disease cognition, compliance with antiviral therapy and self-efficacy of the two groups were analyzed.Results:There were 30 patients in each group completed the research. In the control group, there were 15 males, 15 females, aged (56.28 ± 5.97) years. In the observation group, there were 16 males, 14 females, aged (55.36 ± 6.21) years. After intervention, the scores for perceived benefit and acceptance [(20.36 ± 2.47) and (23.54 ± 2.67)] were higher than those of the control group [(16.33 ± 2.48) and (17.45 ± 2.68)], helplessness score of the observation group was (5.33 ± 0.67), lower than (10.21 ± 2.58) of the control group with significant differences ( t=6.31, 8.82, 10.03, all P<0.05). After intervention, compliance rate in the observation group [93.33% (28/30)] was higher than that in the control group [70.00% (21/30)], with significant difference ( χ2=5.46, P<0.05). After intervention, the General Self-Efficacy Scale score of the observation group was (31.25 ± 3.24), higher than (25.33 ± 2.67) of the control group, with significant difference ( t=7.72, P<0.05). Conclusions:Goal setting theory-guided health management can effectively improve compliance with antiviral therapy among patients with CHB, which may be related to the improvement of disease cognition and self-efficacy, and is worthy of clinical promotion.

Objective:To investigate whether killer immunoglobulin-like receptor(KIR)genotypes and haplotype are associated with the dry eye disease(DED)in a Chinese Han population.Methods:Polymerase chain reaction with sequence-specific primers(PCR-SSP)method was used to genotype KIR genes in 106 DED patients and 220 healthy controls.Results:A total of 23 KIR geno-types were found in DED patients and healthy controls,including 10 newly discovered KIR genotypes.The genotype G and haplotype 4 were associated with respectively increased risk of DED(P=0.025,P=0.004);while the haplotype 2 appeared to have an inverse asso-ciation with the disease(P=0.016).The frequency of KIR genotype B/B in DED patients was also significantly higher than that in con-trol group(P=0.027).KIR haplotype A and B had distinctive centromeric(Cen)and telomeric(Tel)gene-content motifs,and the Cen-B/B was associated with increased risk of DED(P=0.037).Conclusion:There may be an association between KIR genotype and hap-loid type with DED in Han population.

Objective To explore the clinical efficacy of swallowing training combined with Vitalstim neuromuscular electrical stimulation in patients with dysphagia after stroke for providing a scientific basis for improving the swallowing function.Methods A total of 100 patients with post-stroke dysphagia were enrolled and randomly divided into control group(n=50,conventional swallowing training)and observation group(n=50,conventional swallowing training+Vitalstim neuromuscular electrical stimulation),with a total treatment course of 3 weeks.The swallowing functions before and after treatment was compared between two groups.Results After treatment,observation group scored lower on the water swallow test and the Rosenbek Penetration-Aspiration Scale(P<0.05),while higher on the Functional Oral Intake Scale and the Functional Independence Measure as compared with control group(P<0.05).In addition,the score of Nutritional Risk Screening 2002(NRS2002)was higher in observation group than in control group(P<0.05).Conclusion The combination of swallowing training and Vitalstim neuromuscular electrical stimulator can effectively improve the swallowing function of stroke patients and has high clinical application value,worthy of further promotion and research.

Objective:To investigate the relationships among coping styles,negative life events,meaning in life,and psychological resilience in adolescents.Methods:A total of 1 434 adolescents aged 13 to 17 years comple-ted online questionnaire survey.The Simplified Coping Style Questionnaire(SCSQ),Adolescent Self-Rating Life E-vents Checklist(ASLEC),Chinese Meaning in Life Questionnaire(C-MLQ),and Connor-Davidson resilience scale(CD-RISC)were used to assess coping styles,perceived impact of negative life events,experience and pursuit of meaning in life,and ability to cope with and adapt to adversity,respectively.Logistic regression was used to explore the associations among these variables.Results:A total of 723 students(50.4％)tended to adopt negative coping styles when facing adverse events.Positive coping styles were negatively associated with being in senior high school(OR=0.62,P＜0.05)and impact of life events(OR=0.97,P＜0.001),while positively associated with sense of meaning in life(OR=1.04,P＜0.001)and psychological resilience(OR=1.04,P＜0.001).Conclusion:Among adolescents,positive coping styles are inversely associated with impact of negative life events,and positively associ-ated with both the sense of life meaning and psychological resilience.

Objective:To explore the efficacy of different second-line treatment strategies in the real world after progression of first-line immunotherapy and its combination therapies in patients with driver gene-negative advanced non-small cell lung cancer (NSCLC) .Methods:A retrospective analysis was conducted on the clinical data of 93 driver gene-negative advanced NSCLC patients who received first-line immunotherapy and its combination therapies from January 1, 2018 to December 31, 2023 at the First Affiliated Hospital of Xinxiang Medical University and Xinxiang Central Hospital. Patients were categorized into immune checkpoint inhibitors (ICIs) -resistant ( n=43) and ICIs-responsive ( n=50) groups according to whether progression free survival (PFS) exceeded 6 months after first-line treatment. Patients were categorized into ICIs-treated ( n=55) and non-ICIs-treated ( n=38), anti-angiogenic-treated ( n=51) and non-anti-angiogenic-treated ( n=42) groups according to the different second-line treatment strategies after progression of first-line immunotherapy and its combination therapies. The median PFS2 (mPFS2) and median overall survival (mOS) 2 after second-line treatment of each group were compared. The Kaplan-Meier method was used for survival analysis. Results:The mPFS2 and mOS2 of 93 advanced NSCLC patients who progressed after first-line ICIs treatment were 4.9 months (95% CI: 4.1-5.7 months) and 14.7 months (95% CI: 11.2-18.2 months). The mPFS2 of patients in the first-line ICIs-responsive and ICIs-resistant groups were 6.0 and 3.8 months, respectively, with no statistically significant difference ( χ2=2.00, P=0.157), and the mOS2 were 25.3 and 11.3 months, respectively, with a statistically significant difference ( χ2=12.13, P<0.001). The mPFS2 of patients in the second-line ICIs-treated group and the non-ICIs-treated group were 5.2 and 4.6 months, respectively, with no statistically significant difference ( χ2=0.16, P=0.687). The mOS2 were 15.1 and 12.7 months, respectively, with no statistically significant difference ( χ2=0.01, P=0.930). The mPFS2 of patients in the second-line anti-angiogenic-treated and non-anti-angiogenic-treated groups were 4.5 and 6.0 months, respectively, with no statistically significant difference ( χ2=0.41, P=0.525), the mOS2 were 14.7 and 16.8 months, respectively, with no statistically significant difference ( χ2=0.01, P=0.943) . Conclusions:After progression of first-line ICIs therapy in patients with driver gene-negative advanced NSCLC, first-line ICIs-responsive patients have significantly longer OS after second-line treatment compared with ICIs-resistant patients. The efficacy of second-line therapy in patients after progression of first-line ICIs therapy does not show significant differences due to the type of treatment strategies.

Objective To rvaluate the therapeutic efficacy of balloon-dilatation covered stents in the treatment of renal artery stenosis(RAS).Methods The clinical data of 30 patients with RAS,who received intravascular ultrasonography(IVUS)-guided LifeStream balloon-dilatation covered stent implantation at the Affiliated Central Hospital of Dalian University of Technology(Dalian Municipal Central Hospital)of China from August 2022 to December 2023,were retrospectively analyzed.The various parameters of the lumen and the stent were measured,and the performance of the stent was evaluated.Results The minimum original blood vessel diameter below the base of the stenotic segment plaque was 5.40(5.17,5.80)mm and the maximum blood vessel diameter was 6.20(5.80,6.93)mm,which became 6.00(5.80,6.00)mm and 7.90(6.00,8.00)mm respectively after stent release,the differences were statistically significant(both P＜0.05).Before stent release the luminal eccentricity index was(14.72±9.37)％,which was(1.54±9.16)％after stent release,the difference was statistically significant P＜0.05).The instant stent symmetry after stent release was(82.69±14.61)％,and the stent expansion factor was(99.81±10.70)％.Ideal narrow coverage rate was obtained.During operation,poor stent adhesion occurred in 2 patients and renal artery rupture with bleeding occurred in one patient,which were solved after immediate re-expansion treatment.Spearman's correlation analysis showed that stent symmetry,stent expansion factor,and stent eccentricity index did not linearly correlate with the lumen cross-sectional area stenosis rate and the plaque eccentricity index(all P＞0.05).Conclusion For the treatment of RAS,the LifeStream balloon-dilatation covered stent is clinically safe,feasible,and effective with satisfactory immediate clinical outcomes.
