OBJECTIVE: To explore the genetic etiology of 46 Chinese pedigrees affected with Hereditary multiple exostoses (HME) and provide genetic counseling and reproductive intervention. METHODS: Whole-exome sequencing and Sanger sequencing were carried out on 87 patients from the 46 pedigrees to analyze the variants of EXT1 and EXT2 genes. Pathogenicity of the variants was assessed based on the guidelines from the American College of Medical Genetics and Genomics and Association for Molecular Pathology (ACMG/AMP). Prenatal diagnosis and preimplantation genetic testing (PGT) were provided for couples with identified pathogenic mutations. This study was approved by the Medical Ethics Committee of the hospital (Ethics No.: LL-SC-SG-2014-010). RESULTS: In total 17 and 22 pathogenic variants were respectively identified in the EXT1 and EXT2 genes, among which 5 EXT1 and 12 EXT2 variants were unreported previously. Three patients with no family history were found to harbor de novo variants of the EXT1 gene. Twenty nine couples had opted for PGT or underwent prenatal diagnosis following natural conception, and 17 healthy babies were born. CONCLUSION This study has clarified the genetic etiology of 45 HME pedigrees and identified 17 novel variants, which has enriched the mutational spectrum of the EXT1 and EXT2 genes. Reproductive intervention through PGT and prenatal diagnosis have prevented the recurrence of HME in these families.

ObjectiveTo investigate the disease burden of non-alcoholic fatty liver disease （NAFLD） among young people in East Asian countries （including China， North Korea， Japan， Mongolia， and South Korea） in 1990—2023， and to provide a basis for formulating and adjusting the prevention and treatment strategies for NAFLD. MethodsRelated disease burden data of NAFLD among the young people in these five East Asian countries were collected from the Global Burden of Disease 2023 （GBD 2023） database， including incidence rate， prevalence rate， and disability-adjusted life years （DALY）， and the young people were divided into groups based on country， sex， and age. Estimated annual percentage change （EAPC） was used to comprehensively evaluate the changing trend of the disease burden of NAFLD among young people from 1990 to 2023， and the Autoregressive Integrated Moving Average model was used to predict the disease burden of NAFLD among the young people in China. ResultsIn 2023， the standardized incidence rates of NAFLD among the young people in China， North Korea， Japan， Mongolia， and South Korea were 926.57/100 000， 805.83/100 000， 412.66/100 000， 747.66/100 000， and 534.08/100 000， respectively； the standardized prevalence rates of NAFLD among the young people in China， North Korea， Japan， Mongolia， and South Korea were 16 817.94/100 000， 14 500.98/100 000， 8 534.40/100 000， 13 705.28/100 000， and 11 587.93/100 000， respectively； the standardized DALY rates of NAFLD among the young people in China， North Korea， Japan， Mongolia， and South Korea were 6.34/100 000， 10.18/100 000， 5.23/100 000， 47.93/100 000， and 6.76/100 000， respectively. From 1990 to 2023， there was a tendency of increase in the standardized incidence rate of NAFLD among the young people in China， North Korea， Japan， Mongolia， and South Korea， with an EAPC of 0.87%， 0.52%， 0.26%， 0.48%， and 0.87%， respectively； there was also a tendency of increase in the standardized prevalence rate of NAFLD among the young people in China， North Korea， Japan， Mongolia， and South Korea， with an EAPC of 0.99%， 0.49%， 0.24%， 0.59%， and 0.93%， respectively； conversely， there was a tendency of reduction in the standardized DALY rate of NAFLD among the young people in China， Japan， Mongolia， and South Korea， with an EAPC of -2.21%， -2.01%， -0.37%， and -4.62%， respectively， while the standardized DALY rate of NAFLD among the young people in North Korea remained relatively stable， with an EAPC of -0.01%. The subgroup analysis based on sex showed that there was a significant difference in the disease burden of NAFLD between the young people with different sexes in the five East Asian countries， and the subgroup analysis based on age showed that the incidence rate of NAFLD in young people decreased with the increase in age， while the prevalence rate and DALY rate of NAFLD increased with age. In addition， the standardized incidence rate and standardized prevalence rate of NAFLD among Chinese young people would further increase in the future， while there would be a reduction in standardized DALY rate in the future. ConclusionThere is a significant difference in the disease burden of NAFLD in young people across different countries， sexes， and age groups. In the future， targeted prevention and treatment measures should be developed based on the distribution characteristics of the disease burden of NAFLD， in order to effectively reduce the disease burden of NAFLD among young people.

Aim To explore the therapeutic effects of resveratrol(Res)on hepatic inflammation and oxida-tive stress in rheumatoid arthritis(RA),and to eluci-date the relationship of the regulatory mechanism of the Nrf2/Keap1 signaling pathway in it.Methods A mouse model of arthritis was induced using chicken type Ⅱ collagen in combination with complete Freund's adjuvant,and Res was administered by tube feeding for treatment.Serum liver function indices and levels of hepatic inflammation and oxidative stress were detected in mice.An in vitro cellular model of hepatic inflam-mation and oxidative stress was established by treating mouse primary hepatocytes(MPHs)with TNF-α(5μg·L-1),cell proliferation inhibition was detected by CCK-8,and inflammation and oxidative stress-relat-ed indices were detected by protein blotting.The in-trinsic mechanisms by which Res attenuated hepatic in-flammation and oxidative stress in rheumatoid arthritis were explored by treating MPHs with Nrf2 inhibitor and Keap1 overexpression plasmid.Results Res signifi-cantly reduced the levels of inflammation and oxidative stress in hepatic tissues of collagen-induced arthritis mice as well as TNF-α-treated MPHs,and activated the Nrf2/Keap1 signaling pathway.Inflammation and oxidative stress levels in MPHs were exacerbated by the use of Nrf2 inhibitors and Keap1 overexpression,which promoted apoptosis.Conclusion Res attenuates he-patic inflammation and oxidative stress in rheumatoid arthritis via the Nrf2/Keap1 pathway.

Objective:To evaluate the value of peripheral blood systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), carcinoembryonic antigen (CEA), D-dimer, and albumin (ALB) alone or their combination in the diagnosis of early-onset colorectal cancer (EOCRC).Methods:From January 1, 2023 to November 30, 2024, 104 patients with EOCRC (EOCRC group) hospitalized at Renmin Hospital of Wuhan University were enrolled. During the same period, by simple random sampling method, 104 patients with benign colorectal polyps (benign polyp group) and 104 healthy individuals for health examinations (healthy control group) from outpatient department were enrolled. The peripheral blood parameters (including neutrophil count, lymphocyte count, CEA, and others) and pathological characteristics of EOCRC (including TNM stage, tumor differentiation grade, and depth of invasion) were collected. The relationship between peripheral blood parameters and EOCRC pathological features were analyzed. Receiver operating characteristic curves (ROC) were plotted, and the area under the curve (AUC) was calculated to evaluate the diagnostic value. Multivariate logistic regression analysis was performed to analyze the peripheral blood parameters which independently correlated with EOCRC and a combined diagnostic model was established. Simple random sampling method was used to divide the subjects in the negative control group (healthy control group + benign polyp group) and positive group (EOCRC group) into a training set (218 cases) and a validation set (94 cases) at a ratio of 7∶3, and the diagnostic performance of the combined diagnostic model in the training and validation sets was assessed. Hosmer-Lemeshow test and calibration curve were used to evaluate the fit and consistency of the model. Independent sample t-test, one-way ANOVA, Mann-Whitney U test and Kruskal-Wallis H test were used for statistical analysis. Results:EOCRC group had the highest levels of SII(744.03 (473.01, 1 246.28), 437.77 (342.28, 607.47), 497.31 (385.76, 721.63)×10 9/L), NLR(2.42 (1.76, 3.94), 1.96 (1.54, 2.52), 1.91 (1.55, 2.75)), CEA (3.58 (1.96, 20.85), 1.31 (0.95, 1.93), 1.21 (0.76, 2.11) μg/L) and D-dimer (0.36 (0.20, 0.90), 0.19 (0.12, 0.28), 0.18 (0.12, 0.30) mg/L), and the lowest levels of LMR(3.51±1.56, 4.38±1.37, 4.72±1.84) and ALB(42.40 (39.90, 44.70), 44.57 (42.83, 46.25), 44.95 (43.10, 46.58) g/L) than benign polyp group and healthy control group, and the differences were statistically significant ( H=31.18, 16.21, 76.72 and 47.72, F=15.40, H=34.19; all P<0.001). In EOCRC patients, there were statistically significant differences in SII and LMR between patients with different tumor invasion depth ( Z=-2.48, t=2.31; both P<0.05), in CEA between patients with different TNM stage, with or without lymph node metastasis and distant metastasis( Z=-2.68, -2.50 and -2.65; all P<0.05), in D-dimer between patients with different TNM stage, differentiation grade, invasion depth, and with or without lymph node metastasis and distant metastasis ( Z=-2.50, -2.60, -2.06, -2.14 and -3.33; all P<0.05), and in ALB between patients with or without distant metastasis ( Z=-2.52, P=0.012).The AUC of combination of SII, NLR, LMR, CEA, D-dimer, and ALB in differential diagnosis of the healthy control group and the EOCRC group was 0.914 (95% confidence interval (95% CI): 0.870 to 0.958, P<0.001), and the AUC of the combination in differential diagnosis of the benign polyp group and the EOCRC group was 0.904 (95% CI: 0.857 to 0.950, P<0.001). The results of multivariate logistic regression analysis revealed that SII, NLR, LMR, CEA, and ALB were all independently correlated with EOCRC (all P<0.05). The diagnostic model for EOCRC was established by the combination of SII, NLR, LMR, CEA, and ALB, and the AUC of the model in the training set and validation set was 0.911 and 0.883, respectively. The Hosmer-Lemeshow goodness-of-fit test indicated good model fit ( P=0.437). Calibration curve analysis showed strong consistency between predicted probabilities and actual probabilities, and the mean absolute error was 0.015. Conclusions:SII, NLR, LMR, CEA, D-dimer, and ALB all demonstrate diagnostic value in the diagnosis of EOCRC. The combined diagnostic model based on SII, NLR, LMR, CEA, and ALB demonstrates excellent diagnostic performance, which may serve as an adjunctive diagnostic approach for EOCRC.

OBJECTIVE: To investigate the association between ABO blood types and gestational diabetes mellitus (GDM) risk. METHODS: A prospective birth cohort study was conducted. ABO blood types were determined using the slide method. GDM diagnosis was based on a 75-g, 2-h oral glucose tolerance test (OGTT) according to the criteria of the International Association of Diabetes and Pregnancy Study Groups. Logistic regression was applied to calculate the odds ratios ( ORs) and 95% confidence intervals ( CIs) between ABO blood types and GDM risk. RESULTS: A total of 30,740 pregnant women with a mean age of 31.81 years were enrolled in this study. The ABO blood types distribution was: type O (30.99%), type A (26.58%), type B (32.20%), and type AB (10.23%). GDM was identified in 14.44% of participants. Using blood type O as a reference, GDM risk was not significantly higher for types A ( OR = 1.05) or B ( OR = 1.04). However, women with type AB had a 19% increased risk of GDM ( OR = 1.19, 95% CI = 1.05-1.34; P < 0.05), even after adjusting for various factors. This increased risk for type AB was consistent across subgroup and sensitivity analyses. CONCLUSION The ABO blood types may influence GDM risk, with type AB associated with a higher risk. Incorporating it-either as a single risk factor or in combination with other known factors-could help identify individuals at risk for GDM before or during early pregnancy.

Removal of endogenic renal sinus tumors which are located at the renal hilum,is recognized as one of the most challenging surgeries in urology due to the complex anatomical structure.With the help of the high-definition field of vision and flexible robotic arms of the Da Vinci robot system,our team have carried out precision intra-sinus tumor enucleation based on preoperative interactive qualitative and Interactive Quantitative Quality Assurance for 3D Imaging(IQQA-3D)accurate reconstruction technology,as well as the clinical anatomical characteristics of patients with renal sinus tumors.During operation,the renal pedicle is fully dissected,the perihilar fat is cleared,and the tumor capsule is exposed.Subsequently,the blood supply to the kidney is blocked,and the tumor is precisely excised along the tumor capsule.The vascular stumps are sutured point-to-point,and the wound is closed and locked.After the blood supply restores,regional arterial occlusion is performed if necessary to ensure the safety of the surgery and maximize the preservation of renal function.This article discusses the definition of tumor boundaries during robot-assisted endogenic sinus tumor enucleation,the use of intraoperative cooling techniques,and the improvement of surgical safety.

Over the past four decades，China’s response to HIV/AIDS has undergone a profound transformation—from an initial state of nearly absence to a comprehensive，robust，and highly coordinated system. The implementation of the “Four Frees and One Care” policy，the widespread adoption of antiretroviral therapy，and the integration of the “test-and-treat” strategy have collectively shifted HIV/AIDS from a fatal condition to a manageable chronic disease，significantly improving both the quality of life and life expectancy of affected individuals. This article systematically reviews three critical stages in the development of HIV/AIDS prevention and control in China，with particular emphasis on the positive impact of medical advances. It further summarizes key progress in testing capacity，drug accessibility，and service delivery，while highlighting the challenges and directions that lie ahead. This review aims to provide scientific evidence to support the ultimate goal of ending the HIV/AIDS epidemic.

The aim of this paper was to investigate the serotypes,virulence factors and drug resist-ance of clinical isolates of Pasteurella rnultocida of porcine origin in recent years.Morphological screening and polymerase chain reaction(PCR)were used to isolate and identify 119 isolates from nasal swabs and lung tissue samples sent from swine farms in Zhejiang Province from 2010 to 2024.The isolates of Pasteurella multocida were subjected to capsular polysaccharide serotyping,lipopolysaccharide serotyping,virulence factor detection and drug resistance analysis by PCR and Kirby-Bauer disc agar diffusion method(K-B).The results showed that there were 64 strains(53.7％)of A-type,54 strains(45.3％)of D-type and 1 strain(0.9％)of F-type among the capsu-lar polysaccharide serotypes,and 10 strains(8.4％)of L1-type,20 strains(16.8％)of L3-type,86 strains(72.2％)of L6-type,and 3 strains(2.6％)of undetermined type among the lipopolysaccha-ride serotypes.The amplification results of 10 virulence genes showed that the detection rate of virulence genes hgbA,higbB and fimA was over 86.0％,the detection rate of toxA was 8.4％,while the virulence gene tbpA was not detected.There were also differences in the distribution vir-ulence genes in different capsular polysaccharide serotypes.Virulence factor pfhA was detected in type A and F but not in type D.The detection rate of adhesin gene tadD in serotype A(92.2％)was significantly higher than that of type D(9.3％),and,on the contrary,the detection rate of ad-hesin gene hsf-l in serotype D(90.7％)was significantly higher than that of type A(20.3％).Drug resistance analysis revealed that Pasteurella multocida showed high susceptibility to antimi-crobial drugs such as amoxicillin,ampicillin,cephalosporins,doxycycline,fosfenicol and ciprofloxa-cin,and showed strong resistance to antimicrobial drugs such as lincomycin,cotrimoxazole,genta-micin and amikacin,and there were 54 multi-drug resistant strains(78.3％).In summary,capsular polysaccharide serotypes were dominated by type A and D,lipopolysaccharide serotypes were dom-inated by L6,the distribution of some virulence genes varied greatly among different serotypes,and the proportion of multi-resistant strains was high,which provide reference for the prevention and control of this disease.
