Objective:To investigate the impact of early removal of nasogastric tubes on functional recovery after total gastrectomy for gastric cancer patients, to provide scientific evidence for enhanced recovery after surgery strategies in gastric cancer.Methods:A retrospective cohort study was conducted on 102 gastric cancer patients who underwent total gastrectomy at Beijing Friendship Hospital affiliated with the Capital Medical University from March 2018 to July 2022. Patients were divided into two groups based on whether the gastric tube was removed within 24 hours post-operation: the early removal group (within 24 hours, 55 patients) and the non-early removal group (beyond 24 hours, 47 patients). The recovery outcomes, including time to first flatus, time to fluid intake, length of hospital stay, and the incidence of postoperative complications, were compared between the two groups. Non-normally distributed data were expressed as M( Q1, Q3) and compared using the Wilcoxon rank-sum test. Categorical data were expressed as frequencies or percentages and compared using the chi-square test or Fisher′s exact test. To minimize the impact of potential confounders, multivariable linear regression and logistic regression analyses adjusted for propensity scores were further employed to compare quantitative and qualitative data between the groups. Statistical analyses were performed using R software. Results:The exhaust time, water intake time, and hospital stay in the early removal group were 3.0(2.0, 3.5) days, 4.0(3.0, 5.0) days, and 7.0(7.0, 8.0) days, respectively, while those in the non-early removal group were 4.0(3.0, 5.0) days, 6.0(5.0, 7.0) days, and 8.0(7.5, 11.0) days, respectively. Statistically significant differences were observed between the two groups ( P<0.05). However, there was no significant difference in the incidence of postoperative complications between the two groups (5.45% vs 17.02%, P=0.060). Propensity score-adjusted regression analysis suggested that early tube removal might reduce the risk of postoperative complications ( P=0.042). Conclusion:Early removal of nasogastric tubes can significantly accelerate functional recovery after total gastrectomy for gastric cancer patients and may reduce the risk of postoperative complications, providing important clinical guidance for enhanced recovery after surgery management in gastric cancer.

Anti-Sj?gren's syndrome type A（SSA) and anti-Sj?gren's syndrome type B（SSB) antibodies both belong to the antinuclear antibody spectrum and are common in patients with systemic lupus erythematosus, Sj?gren's syndrome and undifferentiated connective tissue disease as well as asymptomatic patients. Approximately 1% of pregnant women are positive for anti-SSA and anti-SSB antibodies and only 1%-3% of the fetuses carried by primiparae with anti-SSA and anti-SSB antibodies show immune-mediated cardiac conduction and structural abnormalities. Due to its low incidence and insidious onset, some pregnant women were diagnosed positive for antibodies against SSA and SSB for the first time only due to fetal heart block or structural abnormalities during pregnancy. Domestic and international research on the effects of anti-SSA and anti-SSB antibodies on fetal heart and the prenatal monitoring, diagnosis, intrauterine treatment and prognosis of fetal cardiac abnormalities related to anti-SSA and anti-SSB exposure are reviewed to guide the clinical work of obstetrics.

Objective: To understand the prevalence of overweight and obesity, dietary habits and main food intake frequency among primary school students in Shenyang, so as to provide a reference for exploring the effect of diet related factors on the development of overweight and obesity in children. Methods: A total of 2 041 students from two primary schools in a certain district of Shenyang were selected by convenience sampling in May 2017, with height and weight measured, meanwhile the questionnaire survey regarding dietary habits and the frequency of main food intake were administered. Results: The rates of overweight and obesity were 18.4% and 22.1% respectively, and the rate of overweight and obesity in boys (21.0%，27.8%) were significantly higher than that in girls (15.8%,16.2%)(χ 2=22.45,53.40，P<0.01). The results of univariate analysis showed that frequency of eating breakfast, eating speed, appetite, picky eaters or not, and the frequency of fruit, seafood and canned food intake were associated with overweight and obesity in primary school students (χ 2=7.67，97.92，229.70，95.88，6.40，6.58，7.96，P<0.05). Multivariate Logistic regression analysis showed that slow eating speed (OR=0.46, 95%CI=0.29-0.69) and normal eating speed (OR=0.47, 95%CI=0.32-0.69) were associated with lower rates of overweight and obesity; good appetite (OR=43.73, 95%CI=5.88-325.36) was associated with higher rates of overweight and obesity in primary school students (P<0.01). Conclusion The detection rate of overweight and obesity is relatively high among primary school students in Shenyang, and the rate of obesity is already higher than that of overweight; The frequency of common food intake has little impact on the development of overweight and obesity in primary school students, but fast eating speed and good appetite are the risks of overweight and obesity among them.

Objective:To report two cases of post-transplantation lymphoproliferative disorders (PTLD) after kidney transplantation in children and review the literature, and to improve clinicians' understanding of PTLD in children.Methods:The clinical data of two children with PTLD admitted to the Children's Hospital of Fudan University were collected and analyzed. The PTLD-related literature of PubMed, Embase, Web of Science, Scopus, Cochrane Library, Wanfang, CNKI, Weipu Database and China Biomedical Literature Service System from the establishment of the database to January 2020 were collected for literature review. Multivariate logistic regression analysis method was used to analyze the influencing factors of prognostic in children with PTLD.Results:Both of the patients had negative Epstein-Barr virus (EBV) and Cytomegalovirus (CMV) before transplantation and anti-thymocyte immunoglobulin (ATG) were induced during transplantation. PTLD in case 1 and case 2 was diagnosed at 3 and 12 months after transplantation, respectively, with positive EBV and CMV serological reaction. The pathological diagnosis was monomorphic PTLD in case 1 and the case 2 was clinically considered as non-hodgkin lymphoma. They all received thrapies of immunosuppressive reduction combined with anti-CD20 monoclonal antibody and chemotherapy. PTLD was relieved and graft function was normal in 2 cases, while case 1 died two and half years after transplantation due to intracranial fungal infection. According to the analysis of 56 children (including 2 cases in this study) with PTLD from the literature review, the median time of PTLD from transplantation was 41.8 months. The initial involved organs were digestive tract [17 cases (30.4%)], respiratory system [8 cases (14.3%)], nervous system [7 cases (12.5%)] and pharyngeal lymph ring [7 cases (12.5%)], respectively. The main pathologic type of PTLD was monomorphic [34 cases (60.8%)]. Fifty-six cases were all positive in EBV serological reaction when PTLD was diagnosed. The treatment included immunosuppressive reduction combined with anti-CD20 monoclonal antibody and chemotherapy. Forty-eight cases of PTLD were relieved, while 8 cases lost graft function. Eleven cases died, including 3 cases due to infection and the other 8 cases due to PTLD. Multivariate logistic regression showed that monomorphic PTLD was a risk factor of death for PTLD children ( OR=21.616, 95% CI 1.007-464.107, P=0.049). Conclusions:PTLD in children with kidney transplantation is mostly associated with EBV infection, and the clinical manifestations are diverse. Monomorphic PTLD has a poor prognosis and high mortality.

Objective: To investigate the affecting factors of type 1 diabetes mellitus(T1DM) in children, and to provide reference for the prevention and treatment measures in the future. Methods: A case-control study was carried out among 106 children diagnosed with T1DM in a hospital in Shenyang. At the same time, 106 healthy children were selected as the control group by 1∶1 matching of age, gender and living area. The early life-related factors that may affect the development of T1DM in two groups were investigated by questionnaire. Results: The average age of diagnosis in 106 cases with T1DM was(8.02±3.49) years, girls accounted for 60.4% and boys 39.6%. Multi-factor Logistic regression analysis showed that high family socioeconomic status and higher education of fathers were associated with lower odds of development of T1DM. Family member smoking(OR=2.51, 95%CI=1.19-5.29), family history of diabetes(OR=2.56, 95%CI=1.18-5.55), maternal obesity(OR=5.42, 95%CI=2.49-11.83) and infection during pregnancy(OR=3.45, 95%CI=1.04-11.46) were associated with higher risk of T1DM(P<0.05). Conclusion The occurrence of T1DM in children is affected by many factors including heredity, maternal health during pregnancy and family economy,highlighting the importance of early life prevention of T1DM.

Objective: To investigate the prevalence and associated factors of eczema in children in order provide reference for the prevention and treatment of eczema. Methods: Two primary schools in a district of Shenyang were randomly selected to conduct a questionnaire survey on 2 240 students in May 2017. Children with eczema need to be diagnosed by a doctor. Results: There were 838 cases of eczema with a reported rate of 37.4%, 38.7% in boys and 36.1% in girls. The age of 6 to 12 months was the peak period of first eczema in children, and the proportion of eczema within 1 year was up to about 70%. Children who have had eczema in the past were now more likely to catch a cold, and the reported rates of allergic rhinitis, asthma and food allergies were also significantly higher. The Logistic regression analysis showed that the mother was unhappy during pregnancy(OR=1.32,95%CI=1.03-1.69), the parents were more educated (OR=1.60, 95%CI=1.19-2.16), and the parents were allergic (OR=1.58,95%CI=1.07-2.33；OR=1.41, 95%CI=1.02-1.94), family history of diabetes(OR=1.95, 95%CI=1.41-2.68), and cesarean(OR=1.33, 95%CI=1.07-1.65) were risk factors of eczema in children. Conclusion The incidence of children eczema is affected by maternal mood during pregnancy, family factors and delivery mode. It is of practical significance to prevent children eczema in early development for reducing the incidence of other allergic diseases in the future.

Objective To analyze the correlation between the single nucleotide polymorphisms (SNPs) in the promoter of Piwil1 gene and gastric cancer. Methods The expression of Piwil1 mRNA in the tumor tissues of 3 patients with gastric cancer was detected by RT-qPCR, and RNA-Sequencing data from the Cancer RNA-Seq Nexus were analyzed for Piwil1 mRNA expression in gastric patients. Blood samples were collected from 24 gastric cancer patients and 29 healthy control subjects for PCR amplification of Piwil1 gene promoter region. The SNP loci in the promoter region of Piwil1 gene were determined by direct sequencing, and the results were analyzed by SnapGene software. Results Analysis of the data from Cancer RNA-Seq Nexus and the results of RT-qPCR in 3 gastric cancer patients all showed significantly increased Piwil1 expression in gastric cancer tissues compared with the adjacent tissues. Seven SNP loci in two CpG regions of the Piwil1 gene promoter were genotyped, and only one SNP locus was found to be related to gastric cancer. The frequencies of GG, GA, and AA genotypes at the rs28416520 locus in CpG 67 region were 79.2％, 16.7％, and 4.1％in the gastric cancer group, and were 37.9％, 55.2％, and 6.9％in the control group, respectively, showing a significantly higher frequency of the GG genotype in gastric cancer group (OR=0.144, 95％CI:0.045-0.564,χ2=9.071, P＜0.01). The frequency of allele G of the rs28416520 locus was significantly higher in gastric cancer group than in the control group (87.5％vs 65.5％;OR=0.271, 95％CI:0.099-0.766,χ2=6.856, P＜0.01). The genotype or allele frequencies of the other 6 SNPs locus did not differ significantly between gastric cancer group and control group. Conclusions The expression of Piwil1 is increased in gastric cancer tissues as compared with the adjacent tissues. The GG genotype and G allele of rs28416520 within CpG 67 region are associated with an increased risk of gastric cancer.
