BACKGROUND: Approximately 40% of individuals with diabetes worldwide are at risk of developing diabetic kidney disease (DKD), which is not only the leading cause of kidney failure, but also significantly increases the risk of cardiovascular disease, causing significant societal health and financial burdens. This study aimed to describe the burden of DKD and explore its cross-country epidemiological status, predict development trends, and assess its risk factors and sociodemographic transitions. METHODS: Based on the Global Burden of Diseases (GBD) Study 2021, data on DKD due to type 1 diabetes (DKD-T1DM) and type 2 diabetes (DKD-T2DM) were analyzed by sex, age, year, and location. Numbers and age-standardized rates were used to compare the disease burden between DKD-T1DM and DKD-T2DM among locations. Decomposition analysis was used to assess the potential drivers. Locally weighted scatter plot smoothing and Frontier analysis were used to estimate sociodemographic transitions of DKD disability-adjusted life years (DALYs). RESULTS: The DALYs due to DKD increased markedly from 1990 to 2021, with a 74.0% (from 2,227,518 to 3,875,628) and 173.6% (from 4,122,919 to 11,278,935) increase for DKD-T1DM and DKD-T2DM, respectively. In 2030, the estimated DALYs for DKD-T1DM surpassed 4.4 million, with that of DKD-T2DM exceeding 14.6 million. Notably, middle-sociodemographic index (SDI) quintile was responsible for the most significant DALYs. Decomposition analysis revealed that population growth and aging were major drivers for the increased DKD DALYs in most regions. Interestingly, the most pronounced effect of positive DALYs change from 1990 to 2021 was presented in high-SDI quintile, while in low-SDI quintile, DALYs for DKD-T1DM and DKD-T2DM presented a decreasing trend over the past years. Frontiers analysis revealed that there was a negative association between SDI quintiles and age-standardized DALY rates (ASDRs) in DKD-T1DM and DKD-T2DM. Countries with middle-SDI shouldered disproportionately high DKD burden. Kidney dysfunction (nearly 100.0% for DKD-T1DM and DKD-T2DM), high fasting plasma glucose (70.8% for DKD-T1DM and 87.4% for DKD-T2DM), and non-optimal temperatures (low and high, 5.0% for DKD-T1DM and 5.1% for DKD-T2DM) were common risk factors for age-standardized DALYs in T1DM-DKD and T2DM-DKD. There were other specific risk factors for DKD-T2DM such as high body mass index (38.2%), high systolic blood pressure (10.2%), dietary risks (17.8%), low physical activity (6.2%), lead exposure (1.2%), and other environmental risks. CONCLUSIONS DKD markedly increased and varied significantly across regions, contributing to a substantial disease burden, especially in middle-SDI countries. The rise in DKD is primarily driven by population growth, aging, and key risk factors such as high fasting plasma glucose and kidney dysfunction, with projections suggesting continued escalation of the burden by 2030.

Objective:To introduce the experience of reconstructing the pelvic floor with a pedicled large omental flap combined with a basement membrane biological mesh in combined pelvic organ resection for locally advanced or locally recurrent rectal cancer combined with sacrococcygeal resection, and to discuss the feasibility, safety, and near-term therapeutic efficacy of this technique.Methods:For patients with sacrococcygeal resection of combined pelvic organs, a basement membrane mesh was used to rebuild the pelvic floor with a pedicled greater omentum flap to isolate the abdominopelvic cavity. The main operation was to pull the greater omentum, which preserved the double vascular arches, to the pelvic floor to cover the pelvic floor, and then the mesh was used to cover the posterior peritoneal defect and pelvic inlet with absorbable sutures of 2-0 or thicker.Results:In this study, a retrospective cohort study was used to collect clinical data through the China Rectal Cancer Combined Pelvic Organs Resections Case Database. Twenty patients with locally advanced or locally recurrent rectal cancer without extra-pelvic metastasis or only oligometastases underwent combined pelvic organ and sacrococcygeal resection in the Department of Anal and Intestinal Surgery of the Second Affiliated Hospital of the Naval Military Medical University during the period of July 1, 2022, to June 30, 2023, and 10 patients underwent simple basement membrane resection with a simple basement membrane. Among them, the pelvic floor were reconstructed by basement membrane mesh alone in 10 cases (mesh only group), and 10 cases were reconstructed the pelvic floor by pedicled large omental flap combined with basement membrane mesh (omental flap-combined mesh group). The recent outcomes of the two groups of patients were studied comparatively. Comparison of baseline data and intraoperative conditions between the two groups showed no statistically significant differences (all P>0.05); the drain removal time in the omental flap-combined mesh group was 26.7 (19-42) days, which was shorter than that in the mesh only group, which was 40.4 (24-56) days ( U=4.125, P=0.001); The empty pelvis healing time in the omental flap-combined mesh group was 29.4 (23~43) days, which was shorter than that of 42.2 (27~58) days in the mesh-only group ( U=4.043, P=0.001); the differences were all statistically significant. The postoperative complication rate of grade ≥III in the omental flap-combined mesh group was 1/10, which was lower than that of 6/10 in the mesh-only group; the difference was not statistically significant when comparing the two groups ( P = 0.057). Follow-up ended on 09/30/2023, with a median follow-up of 9.5 (3-15) months in 20 patients, and all 20 cases survived during the follow-up period, with no tumor recurrence at the surgical site. Conclusion:In locally advanced or locally recurrent rectal cancer undergoing combined pelvic organ resection with sacrococcygeal, compared with reconstruction of the pelvic floor by basement membrane mesh alone, reconstruction of the pelvic floor and isolation of the abdominopelvic cavity by a pedicled greater omentum flap combined with a basement membrane mesh is safe and feasible.

BACKGROUND: Maturity-onset diabetes of the young (MODY) is the most common monogenic diabetes. The aim of this study was to assess the prevalence of MODY in phenotypic type 2 diabetes (T2DM) among Chinese young adults. METHODS: From April 2015 to October 2017, this cross-sectional study involved 2429 consecutive patients from 46 hospitals in China, newly diagnosed between 15 years and 45 years, with T2DM phenotype and negative for standardized glutamic acid decarboxylase antibody at the core laboratory. Sequencing using a custom monogenic diabetes gene panel was performed, and variants of 14 MODY genes were interpreted as per current guidelines. RESULTS: The survey determined 18 patients having genetic variants causing MODY (6 HNF1A , 5 GCK , 3 HNF4A , 2 INS , 1 PDX1 , and 1 PAX4 ). The prevalence of MODY was 0.74% (95% confidence interval [CI]: 0.40-1.08%). The clinical characteristics of MODY patients were not specific, 72.2% (13/18) of them were diagnosed after 35 years, 47.1% (8/17) had metabolic syndrome, and only 38.9% (7/18) had a family history of diabetes. No significant difference in manifestations except for hemoglobin A1c levels was found between MODY and non-MODY patients. CONCLUSION The prevalence of MODY in young adults with phenotypic T2DM was 0.74%, among which HNF1A -, GCK -, and HNF4A -MODY were the most common subtypes. Clinical features played a limited role in the recognition of MODY.

This article discusses the genetic susceptibility or pathogenicity genes of diabetes, and summarizes the progress of gene diagnosis in different types of diabetes.

Objective: To evaluate the association between NLRP2(NLR Family Pyrin Domain Containing 2) gene polymorphisms and classical type 1 diabetes mellitus(T1DM) in Chinese Han population. Methods: A case-control study was conducted in 510 classical T1DM patients from the Department of Metabolism and Endocrinology in the Second Xiangya Hospital affiliated to Central South University and 531 healthy controls in this region. The polymorphisms of rs1043673 in NLRP2 gene were analyzed by MassARRAY. Mann-Whitney U test and χ² test were used to compare the differences between patients and controls. Logistic regression analysis and χ² test were performed to compare the distributions of the alleles and genotypes between T1DM patients and controls. Kruskal-Wallis H test was used to compare the clinical characteristics of different genotypes in T1D patients. Results: The differences of the allele and genotype distributions in rs1043673 of NLRP2 gene were not significant between patients and controls. The polymorphisms of rs1043673 were associated with fasting C-peptide(P=0.029), postprandial 2-h C-peptide(P=0.017), and titer of GADA(P=0.043) in T1DM patients. Conclusion The polymorphisms of NLRP2 gene were associated with the characteristics of T1DM patients.

Objective To investigate the microRNA ( miRNA ) expression level of peripheral blood mononuclear cell ( PBMC) in autoimmune diabetes mellitus ( ADM) which includes type 1 diabetes mellitus ( T1DM) and latent autoimmune diabetes in adults ( LADA ) , T2DM patients, and matched healthy individuals. Methods Patients of T1DM, LADA, and T2DM were recruited in the Second Xiangya Hospital of Central South University from January 2015 to December 2016. The subjects were divided into two groups. The first group was used for high-throughput screening of differentially expressed microRNAs. The second group was used to validate the expression of miR-142-5p and miR-143-3p by real-time quantitative polymerase chain reaction (RT-qPCR). Results (1)The different miRNA expression patterns of PBMC were found among T1DM patients, LADA patients, T2DM patients, and health individuals. ( 2) Compared with T2DM patients and healthy controls, LADA and T1DM patients had down-regulated PBMC miR-142-5p expression, and up-regulated miR-143-3p expression. (3)RT-qPCR validation showed that the expression of miR-142-5p in LADA patients was significantly lower than that in T2DM patients (0.30±0.24 vs 1.33 ± 1.29, P<0.05) . The expression of miR-143-3p in T1DM and LADA was higher than that in T2DM and health individuals. However, no significant differences were found. Conclusion The miRNA expression patterns are different in the PBMC of T1DM patients, LADA patients, T2DM patients, and healthy individuals; the abnormal expressions of miR-142-5p and miR-143-3p may participate in the development of ADM by affecting apoptosis and immune cell differentiation.

Objective    To evaluate the strategy of chemoradiotherapy following endoscopic R0 resection for esophageal cancer in M3-T1b stage. Methods    There were 45 esophageal cancer patients with M3-T1b stage with endoscopic R0 resection followed by additional chemoradiotherapy from ECETC (Esophageal Cancer Endoscopic Therapy Consortium) as a trial group with 34 males and 11 females at age of 61.37±7.14 years. There were 90 patients with esophagectomy from Fudan University Shanghai Cancer Center as a control group with 63 males and 27 females at age of 61.04±8.17 years. Propensity score match (1:2) was used to balance the factors: gender, age, position, depth of invasion and lymphovascular invasion (LVI), which may influence the outcomes. Overall survival (OS) rate, relapse free survival (RFS) rate, and local recurrence rate were compared between the two groups. Result    There was no statistical difference (HR=2.66 with 95%CI 0.87 to 8.11, P=0.179) in terms of OS rate between the two groups. One, two and three years overall survival rate of patients in the control group was 93%, 86%, and 84%, respectively. Nobody died in the trial group within 3 years after surgery. The RFS rate between the two groups didn’t significantly differ (HR=1.48, 95% CI 0.66 to 3.33, P=0.389). One, two and three years RFS rate of patients in the contorl group was 87%, 78%, and 76%, respectively, while 97%, 93%, and 73% in the trial group, respectively. The local recurrence rates between the two groups didn’t significantly differ either ( HR=0.53，95%CI 0.13 to 2.18, P=0.314). One, two and three years local recurrence rate of patients in the control group was 5%, 6% and 6%, respectively, while 0%, 0% and 21% in the trial group, respectively. Conclusion    Similar outcomes are found regarding OS, RFS and local recurrence rates between the two groups. The strategy of endoscopic R0 resection followed by additional chemoradiotherapy has prospect for the treatment of esophageal cancer in M3-T1b stage. And this kind of therapy may be provided for those with risk factors or can not tolerate surgery.

Objective: To analyze vaccination situation of oral live attenuated rotavirus vaccine (LLR strain) among children from six provinces in China. Methods: In 2014, we selected 12 counties in Guangdong, Jiangsu, Chongqing, Jiangxi, Heilongjiang and Gansu provinces by using stratified cluster random sampling method and extract information of children born from January 1, 2008 to December 31, 2012 from Children's Immunization Information System. We investigated ten children of each birth cohort in each county by checking the vaccination certification, and a total of 606 children were investigated. A survey was conducted to check the information of the children's vaccination certification with the data of Children's Immunization Information System by questionnaire including the basic information (province, county, name, gender, birth date, etc) and the rotavirus vaccination (vaccination date, dose, etc) to analyze the rotavirus vaccination situation. Results: 340 of 606 children were male. There were 121, 124, 122, 119 and 120 children born in 2008-2012, respectively. The proportions of the first and the second dose of rotavirus vaccination were 32.8% (199) and 9.7% (59). The proportion of the third dose of rotavirus vaccination among children born between 2008 and 2010 was 3.5% (13) since children born in 2011 and 2012 did not reach the age of third dose vaccination. The proportion of the first dose of rotavirus vaccination in high, middle and low per capita disposable income areas was 45.0% (91), 37.7% (77) and 15.5% (31) respectively (χ²= 43.15, P<0.001). Among 199 children vaccinated with the first dose of vaccine, the vaccination age mainly concentrated in 2 to 21 months, of which the peak was 5 to 13 months (66.8%, 133). The intervals between 2 doses of vaccination were mainly from 12 to 13 months (42.4%, 25) among the 59 children who received at least 2 doses of vaccine. In the 13 children vaccinated with 3 doses, the intervals between the second and the third dose were 12 months (5). Of the 271 doses of rotavirus vaccine vaccinated during 2008-2014, 34.7% (94 doses) were vaccinated in June-August, 88 were vaccinated simultaneously with 18 other vaccines, accounting for 32.5% of the total. Of the 18 other vaccines, inactivated vaccines such as diphtheria vaccine (30 doses), Hib vaccine (14 doses), group A meningitis vaccine (10 doses) were predominant. Conclusion The proportion of rotavirus vaccination was low and the vaccination age was relatively late. The vaccination mode was different from the recommendation of WHO. It is recommended that routine immunization of rotavirus vaccines should be carried out in early-months of children.

Objective To explore effective methods to improve specialized nurses' professional ability and standardize the post management. Methods Since 2015, Hu'nan Children's Hospital has adopted the the three-level (including the national, provincial and hospital level) specialized nurses training and management program to cultivate the hospital-level specialized nurses in neonatology, intensive care, infection and other departments. The training program was carried out in three-level, including the whole hospital, big departments and their own department (small departments). The assessment of the program also covered three parts, including the specialized theoretical knowledge, technical and academic competence. From 2015 to 2016, the professional academic ability and the development of professional technique were censused. The development speed with link relative method and the comparative growth on moving base of specialized nurses' academic and technical competence were calculated. At the same time transfer rate of specialized nurses was censused. Results The qualification rate of 202 hospital-level nurses reached 95.5% in 2015, and that of 244 nurses reached 96.7% in 2016. Over the past two years, the specialized nurses have been responsible for the hospital-level nursing rounds and consultation for 11 times and the department-level nursing ward rounds for 209 times. A total of 19 new technique projects have been approved by the hospital, and 7 hospital-level and above-hospital-level projects have been set up. The number of the overview published have reached 153 and that of published scientific articles beyond the hospital was 231. Conclusions The three-level (including the national, provincial and hospital level) training and post management program of specialized nurses can effectively improve the ability of specialized nurses from the children's hospitals, promote the stability of specialized nursing team, and guarantee the improvement of the quality and influence of specialized nursing.
