OBJECTIVE To investigate the result of human immunodeficiency virus(HIV)screening for the people visiting to a three-A hospital of Sichuan Province and analyze the prevalence of complications with hepatitis B virus(HBV)infection,hepatitis C virus(HCV)infection and Treponema pallidum(TP)infection in the emerging HIV infection patients.METHODS The result of HIV screening for the people who visited to Ziyang Central Hos-pital from Jan.1,2020 to Dec.31,2024 and the test results of HBV,HCV and TP for the emerging HIV infec-tion patients were collected and were summarized and statistically analyzed by SPSS.0 software.RESULTS Totally 289 891 case-times were tested for HIV,1529 cases were previously diagnosed with HIV,465 of whom were tested posi-tive for the first time,there was significant difference in the positive rate of test for the first time among the 5 years(x2=15.998,P=0.003).Totally 353 cases were confirmed positive among the 465 primary positive screening cases.Among the emerging HIV infection patients,the positive rate was higher in the male than in the female(x2=141.141,P＜0.001),and the positive rate was high among the population aged more than 40 year old(x2=11.448,P＜0.001),mi-grant workers(x2=270.110,P＜0.001)and low education level population(x2=25.911,P＜0.001).The detection rate of gp41 was up to 100.00％in strip type testing.The analysis of the ratio of relative light unit(RLU)to Cutoff val-ue(COI)in the initial screening experiment showed that when COI was greater than 50,all of the confirmed tests were positive,when COI ranged between 1 and 5,the false positive rate was 97.06％.The incidence of complica-tion with HBV infection in the emerging HIV infection patients was increased year by year(x2=20.355,P＜0.001),and the incidence of complication with HCV infection was increased in recent two years(x2=10.690,P=0.030).CONCLUSIONS There is no obvious rise of positive rate of HIV screening among the people visiting to the hospital in recent 5 years.The sensitivity of the primary screening of clinical laboratory is high without posi-tive missing test.The positive rates of HBV and HCV are increased among the emerging HIV infection patients.

Objective:To explore the clinical value of combination of contrast-enhanced ultrasound(CEUS)and magnetic reso-nance imaging(MRI)in the diagnosis of parotid gland tumors.Methods:167 patients with parotid gland tumors were diagnosed by CEUS and MRI respectively and in combination.With postoperative pathological diagnosis result as the gold standard,the diagnos-tic value of CEUS combined with MRI(CEUS+MRI)was analyzed.Results:171 tumors were confirmed by postoperative pathology in 167 patients,including 143 benign tumors(83.63％)and 28 malignant tumors(16.37％).The benign tumors were mainly pleo-morphic adenoma(65 tumors,45.45％),Warthin tumor(40 tumors,27.97％)and basal cell adenoma(13 tumors,9.09％).Among the malignant tumors,mucoepidermoid carcinoma(7 tumors,25.00％),adenoid cystic carcinoma(6 tumors,21.43％)and acinic cell carcinoma(3 tumors,10.71％)were the most common.CEUS showed 39 cases of malignant parotid gland tumors and 132 cases of benign parotid gland tumors.The sensitivity,specificity and accuracy rate of CEUS were 57.14％,83.92％and 79.53％respectively.The MRI ADC values were manifested as pleomorphic adenoma＞malignant tumor＞Warthin tumor(P＜0.05).MRI showed 53 cases of malignant parotid gland tumors and 118 cases of benign parotid gland tumors,and the sensitivity,specifici-ty and accuracy rate of MRI diagnosis were 67.86％,76.22％and 74.85％respectively.CEUS+MRI revealed 33 cases of malig-nant parotid gland tumors and 138 cases of benign parotid gland tumors,the sensitivity,specificity and accuracy rate of CEUS+MRI diagnosis were 78.57％,92.31％and 90.06％respectively.The specificity and accuracy rate of CEUS+MRI were significantly higher than those of single examination(x2=4.806,13.951,7.348,13.664,allP＜0.05).Conclusion:Both CEUS and MRI have certain clinical value in the diagnosis of parotid gland tumors,and the specificity and accuracy rate of CEUS+MRI are significantly higher than those of single examination.

Objective:To analyze the surveillance results of brucellosis in Shanxi Province, to gain a understanding of the epidemic characteristics and changing trend of brucellosis in Shanxi Province, and to provide scientific basis for formulating prevention and control strategies and measures for brucellosis.Methods:The surveillance data of brucellosis in Shanxi Province from Infectious Disease Reporting Information Management System of China Disease Prevention and Control Information System, and the active surveillance results of 5 national brucellosis surveillance sites from 2018 to 2023 were collected for descriptive analysis.Results:From 2018 to 2023, a total of 24 041 cases of human brucellosis were reported in Shanxi Province, with the number of cases increased from 2 800 in 2018 to 5 131 in 2023. The annual reported incidence was 11.22/100 000, ranging from 7.56/100 000 to 14.74/100 000, showing an overall upward trend (χ 2trend = 1 377.43, P < 0.001). The epidemic had affected all counties (cities and districts) in the province, mainly concentrated in Linfen City, Jinzhong City, Datong City, and Shuozhou City, with a total of 13 489 cases of human brucellosis reported, accounting for 56.11%. The population distribution was mainly composed of individuals aged 40 - 69 (17 682 cases), males (18 513 cases), farmers (20 295 cases), and household and unemployed individuals (1 017 cases). The onset of the disease showed obvious seasonality, with the peak time from March to August, accounting for 66.39% (15 961/24 041). A total of 14 130 occupational individuals were investigated at the surveillance sites, and 11 141 underwent serological tests, with a positive rate of 5.25% (585/11 141), including 299 new cases. The positive rate of serological tests was relatively high in Qinyuan County, at 8.51% (241/2 832). Etiological culture was conducted on 338 human blood samples, and 43 strains of Brucella were isolated, with a detection rate of 12.72%. All strains were Brucella melitensis, including 42 strains of Brucella melitensis biovar 3. Conclusions:The overall trend of human brucellosis epidemic in Shanxi Province from 2018 to 2023 is on the rise, and it is still at a high level. It is suggested to continue strengthening monitoring, study the epidemic situation in a timely manner, take comprehensive prevention and control measures, and effectively control the spread of brucellosis.

Objective:To carry out a scoping review on eHealth literacy in patients with cardiovascular disease to sort out eHealth literacy from four aspects of concepts, assessment tools, influencing factors and interventions, with a view to informing future research and practice.Methods:Based on Arksey and O'Malley's framework for reporting scoping reviews, the literature on eHealth literacy in patients with cardiovascular disease was systematically searched in PubMed, Web of Science, Embase, Cochrane Library, CINAHL, China National Knowledge Infrastructure, VIP, Wanfang Data, and China Biomedical Database. The search period was from database establishment to May 3, 2024. Literature was screened, summarized and analyzed.Results:A total of 23 papers were included. The concepts and theoretical frameworks on eHealth literacy had their own focus, but no consensus was reached. The most commonly used tool to assess eHealth literacy in patients with cardiovascular disease was the eHealth Literacy Scale. The influencing factors included four aspects of demographic sociological and disease-related factors, psycho-cognitive factors, eHealth literacy knowledge and skills, and other factors. Interventions to improve eHealth literacy among patients with cardiovascular disease primarily included eHealth literacy training and use of portal-related digital toolkit.Conclusions:Currently there is no specific assessment tool for eHealth literacy for cardiovascular disease patients. In the future, eHealth literacy assessment tools need to be revised and improved according to the population characteristics and cultural background of cardiovascular disease patients. E-health literacy among patients with cardiovascular disease is at a moderately low level and is influenced by multiple factors. The influencing factors can be analyzed in depth through large-sample cross-sectional studies or longitudinal studies, and then a variety of intervention programs can be constructed at home or in the community with the help of multimedia and apps, with a view to improving the e-health literacy of patients with cardiovascular diseases.

OBJECTIVES: This study aimed to investigate the perception of dental outpatient care quality from multiple perspectives of administrators, physicians, nurses, and patients and propose nursing care quality evaluation indices that are consistent with the clinical reality to provide reference for the construction of a scientific, systematic, and comprehensive dental outpatient care quality evaluation system. METHODS: A total of 39 interviewees, including 7 administrators, 11 doctors, 11 nurses, and 10 patients, were selected for semi-structured in-depth interviews in five regionally representative tertiary-level A stomatological specialty hospitals nationwide during January-April 2024 by using a multistage sampling method. Colaizzi 7-step analysis was used to analyze and summarize the interview data. Themes were extracted on the basis of the Structure-Process-Outcome (SPO) three-dimensional quality assessment model. RESULTS: Five main themes and 15 secondary themes were extracted from three quality dimensions: structure, process, and result. The related topics of structural quality were as follows: disinfection and isolation norms, equipment and consumable management, nursing manpower ratio and nurse education structure, and emergency capability. The related topics of process quality were as follows: pre-diagnosis risk assessment, patient triage and guidance, communication and attitude, health education, humanistic care, continuous care, specialty operation, and four-hand operation. The related topics of result quality were as follows: satisfaction, adverse event management and analysis, effective complaints and disputes. CONCLUSIONS Structure quality is the foundation, process quality is the core, and result quality is the key in the evaluation of the quality of oral outpatient care. The standardization of disinfection and isolation, equipment and consumable management, allocation of reasonable nursing manpower and post capacity, implementation of high-quality nursing services, and improvement of the quality and satisfaction of medical cooperation are necessary guarantees to ensure the quality of oral outpatient care.

OBJECTIVES: This study aimed to construct an evaluation index system for nursing quality management in outpatient dental clinics based on the structure-process-outcome model and provide an objective standard for the evaluation of nursing quality in outpatient dental clinics. METHODS: Through literature review, multi-subject interviews, and expert meetings, the first draft of the evaluation index for nursing quality management in outpatient dental clinics was formulated. The Delphi method was adopted to select and invite 15 experts in the fields of hospital infection management, nursing management, and specialized oral care from across the country to modify the first draft. RESULTS: The positive coefficients of the experts in the two rounds of consultation were 86.7% and 92.3%, respectively. The total authority coefficients of the experts were 0.791 and 0.717, respectively. The mean scores of the importance and feasibility of the third-level indices in the two rounds of consultation were all ≥4.333; the coefficients of variation were all ≤0.150; and the Kendall's coordination coefficients were 0.308 and 0.184 respectively, with P<0.05 for all. These results indicated that the experts were motivated to participate in this study. They recognized the importance and feasibility of the overall items in this index system, and their opinions were relatively consistent. Finally, an evaluation index system, which included 3 first-level indices, 7 second-level indices, 22 third-level indices, and 69 index connotations, for nursing quality management in outpatient dental clinics was determined. The weights of the three first-level indicators were all 0.333. Patient satisfaction (0.076, outcome dimension), hand hygiene (0.061, outcome dimension), chair care ratio (0.057, structural dimension), and turnover rate (0.057, structural dimension) were the top tertiary indicators in terms of portfolio weight. CONCLUSIONS The construction method of the evaluation index system for nursing quality management in outpatient dental clinics is scientific and reliable. It can provide a reference for the evaluation of the management level of nursing quality in outpatient dental clinics and promote the continuous improvement of nursing quality in outpatient dental clinics.

Iron,a vital trace element and redox-active metal in the human body,is pivotal in cellular processes and en-gages in a multitude of biological reactions.Ferroptosis,an emerging form of regulated cell death,is predominantly instiga-ted by the excessive free iron that catalyzes reactive oxygen species(ROS)production via the Fenton reaction.This process results in the peroxidation of polyunsaturated fatty acids within the cellular lipid membrane,compromising the membrane's integrity and thereby inducing ferroptosis.In the context of diabetic retinopathy(DR),ferroptosis plays a sig-nificant role.The disruption of iron metabolism,the excessive accumulation of ROS,and the imbalance of the antioxidant system are key mechanisms contributing to ferroptosis in retinal tissues and the exacerbation of DR's pathological progres-sion.This review provides a systematic summary and in-depth discussion of the advancements in understanding the role of ferroptosis in DR pathogenesis,intending to offer valuable insights for future research endeavors in this field.

Objective:To explore the association between macrosomia delivery history and adverse pregnancy outcomes in subsequent pregnancies under different stratification of gestational weight gain(GWG).Methods:A retrospective study was conducted on 500 multiparous women with a history of macrosomia delivery who gave birth at The Second Hospital of Jilin University from January 2020 to November 2023.Meanwhile,1500 multiparous women without a history of delivering macrosomic infants were selected as the control group through 1∶3 matc-hing based on age(±1 year).The differences in general characteristics,GWG,and pregnancy outcomes be-tween the two groups were compared.According to the appropriate GWG values recommended by Chinese health industry standards,pregnant women in both groups were classified into insufficient GWG,appropriate GWG,and excessive GWG.Multivariate Logistic regression analysis was used to compare the relationship be-tween a history of macrosomia delivery and adverse pregnancy outcomes under different GWG stratifications.Re-sults:The History of macrosomia group had significantly higher rates of excessive GWG(50.60%vs.48.13%),incidence of gestational diabetes mellitus(GDM)(23.40%vs.17.07%),rate of cesarean section(60.20%vs.45.33%),and rate of macrosomia(26.60%vs.7.87%)compared to the control group(P<0.05).Multivariate Logistic regression analysis showed that a history of macrosomia delivery was an independent risk factor for GDM,cesarean section,and macrosomia in subsequent pregnancies(aOR>1,P<0.05).Stratified analysis based on GWG revealed that,compared with the control group,regardless of the GWG status,the risk of cesare-an section and macrosomia was higher in women with a history of macrosomia delivery(aOR>1,P<0.05).Mo-reover,for those with a history of macrosomia delivery and excessive weight gain during pregnancy,the risk of preeclampsia(aOR 3.167,P<0.05)and GDM(aOR 1.661,P<0.05)was significantly increased.When the GWG was appropriate for pregnant women with a history of macrosomia delivery,there was no significant correla-tion between a history of macrosomia delivery and preeclampsia or GDM(P>0.05).Conclusions:A history of macrosomia delivery increased the risk of multiple adverse pregnancy outcomes,such as GDM,cesarean section,and macrosomia.For multiparous women at different GWG levels,the risk of cesarean section and macrosomia was significantly increased in those with a history of macrosomia delivery.When GWG was appropriate,a history of macrosomia delivery was not found to be an independent risk factor for preeclampsia and GDM.

BACKGROUND:Currently,the pathogenesis of Parkinson's disease is not clear.Relevant studies have shown that α-synuclein and mitochondria are closely related to the pathogenesis of Parkinson's disease.It mainly involves oxidative stress,mitochondrial complex damage,calcium homeostasis,mitochondrial dynamics and mitochondrial quality control.OBJECTIVE:To review the association between α-synuclein and mitochondrial damage in Parkinson's disease.METHODS:The first author searched more than 50 documents from CNKI and WanFang databases from 2010 to 2024 using the keywords of"Parkinson's disease,mitochondrial damage and mechanism,α-synuclein"in Chinese as well as more than 750 documents from PubMed between 2010 and 2024 using the keywords of"Parkinson's disease,alpha-synuclein,mitochondria,oxidative stress,calcium homeostasis,mitophagy,mitochondrial dynamics,mitochondrial protein introduction"in English.Finally,70 documents were included for review.RESULTS AND CONCLUSION:Recent studies have confirmed the important role of mitochondrial dysfunction in the pathophysiology of Parkinson's disease,and the interaction between α-synuclein and mitochondria is a particularly significant factor in the pathogenesis of Parkinson's disease.The cascade of events that begin with naturally unfolded α-synuclein and eventually form mature fibril is collectively known as α-synuclein aggregation.The toxicity of aggregation accumulates in dopaminergic neurons and then disrupts mitochondrial function,thereby triggering Parkinson's disease.Therefore,the underlying mechanism of this bidirectional relationship between α-synuclein and mitochondrial dysfunction may provide new insights into the pathophysiology of Parkinson's disease.

BACKGROUND:The immune response is strongly associated with the pathological development of Parkinson's disease.Studies have shown that the major histocompatibility complex plays a key role in immune response.OBJECTIVE:To summarize the mechanism of major histocompatibility complex regulation of immune response and the effect on the pathological markerα-synuclein of Parkinson's disease.METHODS:"Parkinson's disease,the major histocompatibility complex,innate immunity,adaptive immunity,microglia,T cell,B cell,α-syn,inflammation,MHC-Ⅰ,MHC-Ⅱ"were used as search terms to search the literature in PubMed database.Finally,92 articles were included for reading analysis.RESULTS AND CONCLUSION:(1)Congenital immune response is involved in the occurrence and development of Parkinson's disease,and the change of microglia's pro-inflammatory and anti-inflammatory phenotypes may aggravate the degenerative changes of Parkinson's disease.(2)The phenotype and function of T cells are related to the progression of Parkinson's disease.Regulatory T cells promote the activation of anti-inflammatory microglia and inhibit Th subgroup.B-cell-mediated humoral immunity can clear pathological α-synuclein,and its specific mechanism needs further study.(3)The major histocompatibility complex is closely related to the occurrence of innate and adaptive immunity,and thus affects the inflammation of Parkinson's disease.(4)α-Synuclein can regulate the activation of microglia and the expression of major histocompatibility complex,which leads to inflammatory changes in Parkinson's disease.(5)α-Synuclein is closely related to the immune response of Parkinson's disease and has become an important target for the treatment of Parkinson's disease.
