Objective To evaluate the disease risk of Vibrio parahaemolyticus (VP) in aquatic products of raw food in Guangzhou. Methods VP detection was carried out in aquatic products of raw food sold in Guangzhou from 2009 to 2022. Gene sequence and wgSNP analysis of 30 VP strains (including 15 food strains and 15 patient strains) were performed for the detection rate of pathogenic VP. sQMRA was applied to assess VP risk of aquatic products of raw food. Results The detection rate of VP in raw aquatic products in Guangzhou was 7.30% (98/1 343). The detection rate of TDH virulence gene in patient strains was 86.70% (13/15) , and the detection rate of TRH was 6.67% (1/15). In 15 food strains, TDH and TRH were negative. The WgSNP analysis showed that 2 food strains had high similarity with the patient strains, indicating the same cluster. Risk assessment showed that the number of Vibrio parahaemolyticus infection cases caused by intaking aquatic products of raw food in Guangzhou was 384 ever year. Conclusion The detection rate of VP in aquatic products of raw food is high in Guangzhou , and the detection rate of VP virulence genes in aquatic products of raw food is low. Gene sequence and wgSNP analysis can be used for risk assessment of food pathogenic bacteria. The risk of disease of Vibrio parahaemolyticus in aquatic products of raw food is high.

Objective:To explore the hearing changes of children with different genotypes of SLC26A4 with enlarged vestibular aqueduct（EVA） using the linear mixed effect model（LMM）, providing evidence for the risk prediction of progressive hearing loss. Methods:A total of 48 children with EVA diagnosed in our hospital from January 2017 to January 2024. All subjects underwent two or more auditory tests. According to the results of deafness gene screening and sequencing, the genotypes are divided into: type A: homozygous mutation of c. 919-2A>G, type B: compound heterozygous or heterozygous mutation containing c. 919-2A>G, and type C: no mutation site of c. 919-2A>G of SLC26A4 gene. LMM was used to analyze the hearing thresholds change of 500 Hz, 1 000 Hz, 2 000 Hz, 4 000 Hz and the average in children with different genotypes with age. Results:A total of 92 ears, 314 audiograms of 48 children were included, the median number of audiograms was 3, the median age of initial diagnosis was 4 months, and the median follow-up time was 13 months. According to LMM, the standard deviation of random effects between patients and ears was large. There was no significant difference in hearing thresholds of different frequencies and the average in genotype A, genotype B, and genotype C, indicating that genotype had no effect on hearing threshold. There is an interaction between age and genotype. Taking genotype C as the reference, children with genotype B had the lowest increase in 500 Hz, 1000 Hz, and the average hearing threshold, followed by type A. Conclusion:EVA children exhibit substantial inter-individual/ear hearing threshold variability. Low-frequency thresholds progress slower than high frequencies. Genotype modulates progression rates, with wild-type（Type C） demonstrating fastest deterioration, supporting personalized auditory monitoring strategies.

Objective To analyze the status of occupational disease hazards in Shantou City for 2019 to 2022 and propose corresponding management measures. Methods Technical reports on various occupational-disease-specific activities in Shantou City from 2019 to 2022 were collected and the data were comprehensively analyzed. Results Among the 3 066 enterprises surveyed in the 2020 occupational disease hazard investigation in Shantou City, occupational hazards were reported in 2 982 enterprises (accounting for 97.3%), with 2 955 being small and micro enterprises, accounted for 99.1%(2 955/2 982). The exposure rate of occupational hazards was 58.7% (42 894/73 054) among workers in the surveyed enterprises, with dust and noise exposure rates of 59.7% and 77.8%, respectively. The reported rate of occupational disease hazard projects by employers, regular detection rate of workplace occupational hazards, detection rate of occupational medical examination among workers, and occupational health training rate of key responsible personnel and occupational health management staff were 8.4%, 1.4%, 2.4%, and 4.3%, respectively. The results of occupational hazards monitoring of workplace in key industries from 2019 to 2022 showed that noise had the highest rate of exceeding national standards workplace, followed by silica dust, accounting for 34.2% and 13.8%, with the on-site exceedance rate of 32.2% and 10.0%, respectively. From 2019 to 2022, 31 suspected occupational disease cases were identified in key occupational disease monitoring, including 27 suspected cases of occupational pneumoconiosis and four suspected cases of occupational noise-induced deafness. Conclusion The workers in Shantou City have a high exposure rate to occupational hazards, and the occupational health management level of employers remains low, with noise and silica dust being the most severe occupational hazards. It is essential to improve technical support and service system development for occupational disease prevention and treatment, strengthen supervision and management in key industries and positions, explore occupational health assistance mechanisms for small and micro enterprises, and enforce employers' responsibility in occupational disease prevention to protect workers' occupational health and safety.

Objective The objective of this study was to establish a mouse model of allergic rhinoconjunctivitis and investigate the role of the NLRP3 signaling pathway in allergic rhinoconjunctivitis.Methods Thirty-three female C57 mice(SPF)were randomLy divided into 3 groups:the control group,the experimental group,and the NLRP3-/-group.On days 0,4,7,14,and 21,the experimental group and NLRP3-/-group received a 0.2 mL intraperitoneal injection of medicine containing OVA(100 μg)and adjuvant Al(OH)3(4 mg),respectively.After an interval of 3 days,each eye and nose were dosed with 10 μL of 5%OVA for five consecutive days a week to induce allergic symptoms.During sensitization and excitation stages,the control group was replaced with an equiva-lent amount of PBS.Ocular and nasal symptoms were observed and scored.The levels of OVA-specific IgE,IL-4,IL-17,and IL-18 in serum were measured using ELISA,while changes in palpebral conjunctiva and nasal mucosa were assessed by hematoxylin-eosin staining.The expression of NLRP3 mRNA in conjunctival tissue and nasal mucosa was determined using real-time PCR analysis.Statistical analysis was performed using SPSS17.0 software with P<0.05 considered as statistically significant difference.Results The experimental group and NLRP3-/-group exhibited induced nasal and ocular allergic symptoms.In the experimental group,the duration of nasal allergy symptoms was(10.500±1.080)days,while the duration of eye allergy symptoms was(20.300±2.058)days.In the NLRP3-/-group,the duration of nasal allergy symptoms was(13.400±1.955)days,and for eye allergy symp-toms it was(20.900±2.132)days.The duration of nasal allergies in the NLRP3-/-group significantly exceeded that in the experimental group(P<0.05),whereas there were no significant differences observed in eye allergy durations between these two groups(P>0.05).Levels of OVA-specific IgE,IL-4,and IL-17 were significantly higher in both the experimental and NLRP3-/-groups compared to those in the control group(P<0.05).Additionally,serum IL-18 content increased significantly in the experimental group when compared with both control and NLRP3-/-groups(P<0.05).Conjunctival tissue lesions as well as nasal mucosa damage were evident in both experimental and NLRP3-/-groups.mRNA expression levels of NLRP3 within conjunctival tissue and nasal mucosa from the experimental group showed a significant increase when compared to those from both control and NLRP3-/-groups(P<0.05).Conclusion Allergic rhinoconjunctivitis pathogenesis is influenced by various factors;however,the involvement of NLPR3 signaling pathway promotes its development.

Objective To study the prognostic factors of progressive hearing loss among children with large vestibular aqueduct syndrome(LVAS).Methods The clinical data of 49 children(95 ears)with LVAS who re-ceived at least two hearing tests from January 2017 to January 2023 in our hospital were retrospectively analyzed,and they were divided into two groups according to the progression of hearing loss:the stable group(55 ears)and the progressive group(40 ears).The effects for progressive hearing loss of initial age,gender,laterality,imaging features,audiometric data,and incomplete partition type Ⅱ(IP-Ⅱ)and SLC26A4(type A,B,C,D)genotypes were analyzed by univariate and multivariate Cox regression analysis.The potential prognostic factors were further verified by Kaplan-Meier survival analysis.Results Each dB decrease in the initial average hearing threshold in-creased the expected hazard by 7.03％(P=0.02).Incomplete partition type Ⅱ(IP-Ⅱ)was associated with 5.11 hazard ratio(95％CI,1.81 to 14.45,P=0.002).Genotype C was associated with 6.13 hazard ratio for progressive hearing loss(95％CI,2.07 to 18.13,P=0.001).Conclusion The initial average hearing threshold,IP-Ⅱ,and SLC26A4 genotype C were significant effect factors of progressive hearing loss in patients with LVAS.This could predict the progression of hearing loss in children with LVAS and help identify patients at high risk for progressive hearing loss.

Objective:To understand the clinical characteristics of human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS) patients with renal injury after antiviral therapy in Henan Province, and to explore the risk factors of renal injury.Methods:A cross-sectional study was conducted to investigate HIV infection/AIDS patients receiving antiviral therapy in Zhengzhou Sixth People′s Hospital, Anyang Fifth People′s Hospital, Hebi Third People′s Hospital, Luo Yang Zhoushan Hospital and Lankao Central Hospital in Henan Province from April 1 to September 30, 2023. The clinical information including basic data, antiviral therapy regimens and comorbidities, and laboratory test results (blood urea nitrogen, serum creatinine, blood uric acid, urine routine, urine microalbumin, urine α 1-microglobulin (α 1-MG), urine β 2-microglobulin (β 2-MG), urine retinol binding protein (RBP), urine creatinine, HIV viral load, CD4 + T lymphocyte count) were collected. Multivariate binary logistic regression was used to analyze independent risk factors for renal injury. Results:A total of 2 526 HIV infection/AIDS patients were included, with the age of (45.52±14.28) years and 2 156 (85.4%) males. The main route of transmission was sexual transmission (91.6%, 2 314/2 526). The duration of antiviral therapy was 5.00(2.92, 8.00) years. Tenofovir (TDF)+ lamivudine (3TC)+ non-nucleoside reverse transcriptase inhibitors (NNRTI) accounted for 55.3%(1 396/2 526) of the current antiviral therapy regimen. The percentage of HIV viral load <50 copies/mL was 93.0%(2 350/2 526). The CD4 + T lymphocyte count was 476(337, 645)/μL. There were 156 patients (6.2%) complicated with hepatitis B and/or hepatitis C, 205 patients (8.1%) with diabetes, 379 patients (15.0%) with hyperlipidemia, and 189 patients (7.5%) with hyperuricemia. A total of 1 040 patients (41.2%) with renal injury were found through renal function test, including 355 cases (14.1%) with estimated glomerular filtration rate (eGFR) <60 mL/(min·1.73 m 2) or urine protein positive or urine albumin creatine ratio (UACR) ≥30 mg/g, 682 patients (27.0%) with pure tubular injury presented with only positive for urinary α 1-MG, urinary β 2-MG, or urinary RBP. eGFR< 60 mL/(min·1.73 m 2) was found in 71 cases (2.8%), eGFR from 60 to 89 mL/(min·1.73 m 2) was found in 509 cases (20.2%), and eGFR≥90 mL/(min·1.73 m 2) was found in 1 946 cases (77.0%). A total of 138 patients (5.5%) were identified as having combined chronic kidney disease (CKD). Among them, 110 patients (79.7%) were in CKD stages 1 to 2, and 117 patients (84.8%) were in urinary albumin A2 grade. Multivariate analysis of 355 patients with renal injury who had eGFR<60 mL/(min·1.73 m 2) or positive urine protein in urine routine or UACR ≥30 mg/g showed that ages of 50 to 69 years old (odds ratio( OR)=2.189, 95% confidence interval ( CI) 1.333 to 3.596, P=0.002)), ≥70 years old ( OR=5.190, 95% CI 2.912 to 9.248, P<0.001), female ( OR=1.685, 95% CI 1.241 to 2.286, P=0.001), combined opportunistic infection ( OR=2.521, 95% CI 1.567 to 4.056, P<0.001), combined hepatitis B ( OR=1.962, 95% CI 1.110 to 3.467, P=0.020), combined hepatitis C ( OR=1.883, 95% CI 1.043 to 3.400, P=0.036), combined diabetes ( OR=2.703, 95% CI 1.911 to 3.821, P<0.001), using TDF for two to four years ( OR=1.674, 95% CI 1.103 to 2.459, P=0.015), using TDF for greater than or equal to five years ( OR=1.880, 95% CI 1.287 to 2.746, P=0.001), using TDF combined with lopinavir/ritonavir (LPV/r) ( OR=3.610, 95% CI 2.273 to 5.734, P<0.001) and using TDF combined with non-LPV/r ( OR=1.495, 95% CI 1.036 to 2.157, P=0.031) were the risk factors of renal injury. Conclusions:There is a high proportion of renal injury among HIV infection/AIDS patients after antiviral therapy in Henan Province, including CKD and simple renal tubular injury. Older age, female, comorbidities, and long-term use of TDF are risk factors for renal injury.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
