Objective: To investigate the relationship between relative grip strength and hyperuricemia (HUA) levels in university freshmen, and to explore the potential value of muscle function indicators in HUA prevention among young populations, so as to provide new scientific evidences for HUA control in the demographic. Methods: Utilizing health examination data from 1 744 freshmen enrolled in a Shaanxi Province university in September 2024, absolute grip strength was measured using CAMRY electronic dynamometers, with relative grip strength subsequently calculated. Spearman correlation analysis was employed to examine relationships between student characteristics and relative grip strength, and binary Logistic regression models assessed the association strength between relative grip strength and HUA. Results: The overall HUA detection rate among freshmen was 29.8%, with significant gender differences (male:43.1%; female:24.0%; χ 2=64.62, P <0.01). Correlation analysis revealed significant associations between relative grip strength, body weight, height, body mass index (BMI) and HUA in both genders (boys: r =-0.27, 0.54, 0.11 , 0.53; girls: r =-0.18, 0.33, 0.08, 0.33, all P <0.05). Binary Logistic regression demonstrated that each standard deviation increase in relative grip strength reduced HUA risk by 77% in males ( OR=0.23, 95%CI =0.14-0.37) and 80% in females ( OR=0.20, 95%CI =0.11-0.36) (both P <0.01). Conclusions Relative grip strength represents a significant factor associated with HUA in university students. Incorporating muscle strength training into HUA prevention programs and establishing muscle function based HUA risk warning systems should be considered.

AIM: To investigate the influence of relevant inflammatory markers in peripheral blood on the progression of neovascular glaucoma(NVG)secondary to diabetic retinopathy(DR)patients.METHODS: Retrospective case-control study. Patients were categorized into two groups based on the presence or absence of NVG: those with proliferative diabetic retinopathy(PDR)alone(PDR group, n=148)and those with NVG secondary to PDR(NVG secondary to PDR group, n=142). Peripheral blood inflammatory markers were evaluated, including white blood cell-related indices, neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR), monocyte-to-lymphocyte ratio(MLR), and systemic immune-inflammation index(SII). The distinctions in peripheral blood inflammatory markers between the two groups of patients and their relationships with NVG secondary to PDR were analyzed.RESULTS:No statistically significant differences were observed in basic characteristics between the two groups, confirming their comparability. However, significant differences were found in eosinophil percentage and MLR between the PDR group and the NVG secondary to PDR group(all P<0.05), with both values being significantly higher in the NVG secondary to PDR group. Multivariate Logistic regression analysis revealed that the eosinophil percentage and the MLR were factors influencing the development of patients with NVG secondary to PDR.CONCLUSION: Eosinophil percentage and MLR may be associated with the progression of PDR to NVG, and could serve as potential predictive markers for NVG development in PDR patients.

Objective To analyze the prevalence, annual trends, and co-morbidity trends of common chronic diseases among workers in a large automotive industry from 2019 to 2021, and to provide a scientific basis for the health management of workers in the automotive industry. Methods The health examination data of workers in a large automotive industry from 2019-2021 were analyzed. Trends in the prevalence of chronic diseases and co-morbidities were analyzed using Join Point software and trend χ² test. Results The prevalence of metabolic syndrome, hyperuricemia, and fatty liver in the 2019 – 2021 health checkups of workers in this enterprise increased at an average rate of 9.27%, 11.35%, and 3.99% per year, respectively. The prevalence of metabolic syndrome, hyperuricemia, and fatty liver in male workers showed an increasing trend at an average rate of 7.05%, 9.25%, and 2.91% per year, respectively. The prevalence of metabolic syndrome in female workers showed an increasing trend at an average rate of 20.76% per year. The prevalence of metabolic syndrome, hyperuricemia and fatty liver was on the rise in the age groups ≤ 29 years old and 40 – 49 years old. The proportion of metabolic syndrome and its co-morbidity with one or two common chronic diseases showed an increasing trend. Conclusion The prevalence and co-morbidity of common chronic diseases in this enterprise are generally on the rise. The enterprise should focus on health education and preventive care for chronic diseases among workers aged ≤ 29 and 40 – 49 years old and male workers and control the annual increasing trend of metabolic syndrome among female workers and workers in the age group ≤ 29 years.

Data analysis models may assist the transmission of traditional Chinese medicine （TCM） experience and clinical diagnosis and treatment， and the possibility of constructing a “data-knowledge” dual-drive model was explored by taking gastric precancerous state as an example. Data-driven is to make clinical decisions around data analysis， and its syndrome-differentiation decision-making research relies on hidden structural models and partially observable Markov decision-making processes to identify the etiology of diseases， syndrome elements， evolution of pathogenesis， and syndrome differentiation protocols； knowledge-driven is to make use of data and information to promote decision-making and action processes， and its syndrome-differentiation decision-making research relies on convolutional neural networks to improve the accuracy of local disease identification and syndrome differentiation. The “data-knowledge” dual-driven model can make up for the shortcomings of single-drive numerical simulation accuracy， and achieve a balance between local disease identification and macroscopic syndrome differentiation. On the basis of previous research， we explored the construction method of diagnostic assisted decision-making platform for gastric precancerous state， and believed that the diagnostic and decision-making ability of doctors can be extended through the assistance of machines and algorithms. Meanwhile， the related research methods were integrated and the core features of gastric precancerous state based on TCM syndrome differentiation and endoscopic pathology diagnosis and prediction were obtained， and the elements of endoscopic pathology recognition based on TCM syndrome differentiation were explored， so as to provide ideas for the in-depth research and innovative application of cutting-edge data analysis technology in the field of intelligent TCM syndrome differentiation.

Objective:To explore the clinical phenotype and genetic etiology for a Chinese pedigree affected with Autosomal dominant polycystic kidney disease (ADPKD).Methods:A pedigree with ADPKD diagnosed at the Department of Gynaecology of the First Affiliated Hospital of Zhengzhou University in December 2020 was selected as the study subject. Clinical data of the pedigree was collected, and whole exome sequencing (WES) was carried out for the proband. Candidate variants were verified by Sanger sequencing of the proband and her relatives. This study was approved by the First Affiliated Hospital of Zhengzhou University (Ethics No. KS-2018-KY-36).Results:Fetal ultrasonography showed increased volume and parenchymal echogenicity in both kidneys. The fetus was found to harbor c. 11098C>T (p.R3700C) and c.11039T>C (p.F3680S) compound heterozygous variants of the PKD1 gene, which were respectively inherited from its mother and father. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were predicted to be likely pathogenic (PM1+ PM2_Supporting+ PP3). Conclusion:The c. 11098C>T (p.R3700C) and c. 11039T>C (p.F3680S) compound heterozygous variants of the PKD1 gene probably underlay the ADPKD in the fetus. Above finding has provided guidance for the genetic counseling and prenatal diagnosis for this pedigree.

Objective:To investigate the effect of dexamethasone mixed with ropivacaine for cervical nerve pathway blockade on the postoperative swallowing function in patients undergoing thyroid surgery.Methods:This was a prospective randomized controlled trial. One hundred twenty-four patients, regardless of gender, aged 18-60 yr, of American Society of Anesthesiologists Physical Status classification Ⅰor Ⅱ, who underwent elective thyroidectomy at Xuzhou Cancer Hospital from March to December 2023, were selected and divided into test group (DR group, n=62) and control group (R group, n=62)using a random number table method. After induction of total intravenous anesthesia, bilateral cervical nerve pathway blockade was performed, dexamethasone 5 mg and 0.25% ropivacaine 10 ml were injected in DR group, and 0.25% ropivacaine 10 ml was injected in group R. Main outcome measures: The swallowing function was assessed using Standard Swallowing Assessment scale at 1 and 6 days postoperatively, and the occurrence of swallowing dysfunction (abnormal in any indicator) was recorded. Secondary outcome measures: numerical rating scale scores were recorded immediately after tracheal extubation and at 4, 8, 12, 24 and 48 h after tracheal extubation in both static and swallowing states. Voice function was evaluated using the Voice Handicap Index-10 at 1 and 6 days postoperatively. The use of ketorolac tromethamine and occurrence of adverse reactions after surgery were recorded. Results:Sixty-one patients were finally included in DR group and 60 patients in R group. Compared with R group, the Standard Swallowing Assessment scale scores at 1 and 6 days after operation and incidence of swallowing disorders at 1 day after operation were significantly decreased, the numerical rating scale scores at 8 and 12 h after tracheal extubation in the static state and at 4-24 h after tracheal extubation in the swallowing state were decreased, the incidence of postoperative nausea and vomiting and Voice Handicap Index-10 scores at 1 day after operation were decreased, and the number of patients who used ketorolac tromethamine was reduced in DR group ( P<0.05). Conclusions:Dexamethasone mixed with ropivacaine for cervical nerve pathway blockade can improve the postoperative swallowing function in patients undergoing thyroid surgery.

[摘 要] 目的：探讨结直肠癌（CRC）组织中磷酸甘油酸变位酶1（PGAM1）的表达及其与患者预后的关系，研究PGAM1对CRC细胞增殖、迁移和侵袭的影响。方法：选择2003年3月至2008年11月间在天津医科大学肿瘤医院手术切除的30例CRC患者的肿瘤组织标本及临床资料，采用免疫组织化学染色法检测CRC组织中PGAM1蛋白的表达，分析PGAM1表达与患者临床病理特征的关系，Kaplan-Meier生存分析法比较PGAM1高表达与低表达患者的OS、PFS来评价PGAM1表达与患者预后的关系。利用RNA干扰技术分别将si-PGAM1及si-NC质粒转染至HCT-116和SW480细胞，WB法检测转染细胞中PGAM1蛋白的表达水平，CCK-8、Transwell实验分别检测敲低PGAM1对CRC细胞增殖、迁移和侵袭的影响。结果：30例CRC组织中PGAM1阳性染色定位于CRC细胞的细胞质，其中33.3%（10/30例）呈高表达。虽然PGAM1高表达与CRC患者年龄、性别、组织学类型、肿瘤大小、淋巴结转移、远处转移及临床TNM分期无关（均P>0.05），但是PGAM1高表达与低表达患者相比其OS、PFS显著缩短。在CRC细胞中敲低PGAM1后，细胞的增殖、迁移和侵袭能力均显著降低（均P<0.05）。结论：CRC组织中PGAM1呈高表达，PGAM1高表达的患者预后较差；敲低PGAM1后细胞的增殖、迁移及侵袭能力均显著降低，提示PGAM1可能是CRC患者预后的生物标志物。

Objective:To investigate the clinical features and prognosis of patients with choroidal tuberculoma.Methods:A retrospective and observational study. From 2011 to 2022, 15 patients (16 eyes) with choroidal tuberculoma diagnosed and treated in Department of Ophthalmology, Shanghai Eye & ENT Hospital of Fudan University were included. The patients underwent examinations including best corrected visual acuity (BCVA), fundus color photography, optical coherence tomography (OCT), fluorescein fundus angiography (FFA), and indocyanine green angiography (ICGA). Chest CT examination, purified protein derivative test and interferon-γ release test were also performed. BCVA was performed using the Snellen visual acuity chart, which was converted to Logarithm of the minimum angle of resolution (logMAR) visual acuity when recorded. All the patients received antitubercular therapy and the duration was 12-15 months. Thirteen patients were combined with oral corticosteroids. The average follow-up time was 36 months. Rank sum test was used to compare logMAR BCVA before and after treatment.Results:Among the 15 patients, 5 were male and 10 were female; 1 case was bilateral involvement; 7 patients had a strong positive tuberculin skin test; 8 patients had a positive interferon-γ release assay. Six patients had pulmonary tuberculosis. One patient had peritoneal tuberculosis. Lesions were located in the posterior pole in 12 eyes, 1 eye with papillary tuberculoma. Peripheral lesions were found in 4 eyes. There were 9 eyes each with anterior segment inflammation or vitreous inflammation; 7 eyes were with exudative retinal detachment. OCT examination revealed a hyporeflective thickening of the choroidal stroma, the corresponding elevation of the retina, and often accompanied by subretinal fluid. FFA revealed hyperfluorescence of the mass and fluorescence accumulation with subretinal fluid at the late stage. ICGA revealed hypofuorescence of the lesion. The lesions subsided after treatment, and there was no recurrence during follow-up period. Cataract surgery was performed in 4 eyes due to complicated cataract. One eye undergone vitrectomy due to secondary rhegmatogenous retinal detachment. Anti-vascular endothelial growth factor therapy was performed in 1 eye due to secondary choroidal neovascularization. Ocular wall perforation occurred in 1 eye, and the condition was stable after treatment. Before treatment, the average logMAR BCVA was 1.02±0.57, which improved to 0.31±0.35 after treatment. The difference between the mean logMAR BCVA before and after treatment was statistically significant ( P<0.05). Conclusions:Combination of medical history, clinical manifestations, laboratory tests, and imaging can assist in the diagnosis of choroidal tuberculoma. The main manifestations are subretinal yellowish-white lesions in posterior pole. Standardized anti-tuberculosis therapy can effectively improve the prognosis of vision.
