Objective To explore the influencing factors of olfactory dysfunction in patients with Parkinson's disease(PD)and conduct a systematic review and Meta-analysis.Methods Articles on factors influencing olfactory dysfunction in PD were retrieved from databases including SinoMed,VIP,China National Knowledge Infrastructure,Wanfang Data Knowledge Service Platform,Web of Science,PubMed,Cochrane,Embase,and MEDLINE.The search period spanned from the inception of each database to November 30,2024.Results A total of 13 articles(with a total sample size of 2465)were included,with a total of 18 influencing factors summarized as two themes:core features and progression factors of PD,and individual background and environmental interaction factors.Meta-analysis showed that age(MD=1.01,95％CI:-0.46-2.49,P=0.18),smoking(OR=0.88,95％CI:0.57-1.37,P=0.57),and constipation(OR=1.22,95％CI:0.38-3.93,P=0.74)were not factors affecting olfactory dysfunction in PD patients.Conclusion Factors influencing olfactory dysfunction in PD are predominantly associated with non-motor symptoms.Intervention strategies targeting non-motor symptoms(such as improving sleep quality,vitamin D supplementation,and early cognitive training)may provide novel approaches for delaying the progression of olfactory dysfunction.

Objective To explore the impact of the TINCR-MAF:MAFB transcription factor network on the expression of proliferation and differentiation-related genes in keratinocytes,to verify the role of this network in the occurrence and development of psoriasis and its potential mechanisms.Methods Employed RNA interference technology to knock down TINCR gene expression,and the proliferation ability of keratinocytes was assessed using the CCK-8 method.Additionally,qRT-PCR and Western blot analyses were conducted to evaluate the RNA and protein expression levels of TINCR,MAFB,and KLF4 genes.Immunohistochemical methods were used to detect the expression of KLF4 protein in psoriasis tissues.Results After TINCR gene siRNA interference,the proliferation ability of keratinocytes significantly decreased at 24,48,and 72 hours(P<0.001),indicating that the TINCR gene plays a critical role in cell proliferation.The results of qRT-PCR and Western blot analyses showed that the RNA and protein expression levels of TINCR,MAFB,and KLF4 genes were significantly reduced(P<0.001),suggesting that TINCR may influence the differentiation of keratinocytes by regulating the expression of MAFB transcription factor and KLF4 differentiation-related genes.Furthermore,immunohistochemical results indicated that the expression of KLF4 protein was significantly elevated in psoriasis tissues compared to normal skin tissues,suggesting that KLF4 plays an important role in the pathogenesis of psoriasis.Conclusions The TINCR-MAF:MAFB transcription factor network may participate in the occurrence and development of psoriasis by affecting the proliferation and differentiation of keratinocytes.This finding provides a new perspective on the pathogenesis of psoriasis and potential targets for future therapeutic strategies.

Objective To evaluate the biochemical indicators,nutritional status,and immune levels of pa-tients with pulmonary aspergillosis(PA)and other pulmonary diseases,and to construct a predictive model for PA so as to improve the diagnostic efficacy of clinical PA.Methods A total of 40 PA patients and 39 pa-tients with other pulmonary diseases who were hospitalized in the hospital from January 2020 to August 2022 were retrospectively analyzed.The expression trends and differences of serum 1,3-β-D Glucan(G test),galac-tomannan test(GM test),biochemical indexes,blood routine indexes and immune cell subsets were analyzed and compared.The receiver operating characteristic(ROC)curve and binary Logistic regression analysis were used to construct the predictive model for PA by the combination of clinical indicators.Results Serum GM test,G test,albumin,hemoglobin,hematocrit,lymphocytes,B lymphocytes,CD44 T lymphocytes and CD4/CD8 ratio displayed significant differences between PA patients and patients with other lung disease(P＜0.05).The levels of GM test in alveolar lavage fluid of PA patients were significantly higher than that in the serum,and the differences were statistically significant(P＜0.05).The ROC curve analysis showed that the GM test,as an independent predictor of PA,had good predictive accuracy[0.85＜area under the curve(AUC)＜0.95].Besides,albumin,natural killev cells,CD4+T lymphocytes and CD4/CD8 ratio had general predictive efficacy(0.70＜AUC＜0.85).The prediction efficacy of G test and B lymphocytes was poor(AUC＜0.70).The Logistic regression analysis showed that the combination of GM test and serum albumin could construct the optimal prediction model,and the prediction formula of the combined model was as fol-lows:Logit(P)=17.781× GM-0.131×albumin+1.394.The prediction accuracy of the combined model was 0.924(95％CI:0.865-0.982),the sensitivity was 87.5％,the specificity was 81.2％,and the cut off value was 17.781×GM-0.131×albumin-1.735.Conclusion This study retrospectively analyzed the differences in various clinical indicators between patients with PA and patients with other pulmonary diseases,and then screen the key clinical indicators as candidate predictors which displayed significantly different ex-pression between the two groups.The optimal prediction model for the diagnosis of PA is constructed by the combination of GM test and serum albumin through ROC curve and Logistic regression analysis.This model may significantly improve the diagnostic efficiency of PA in clinical,and provide the reference for the early di-agnosis and effective treatment of PA patients.

The prevention and control requirements for HIV/AIDS vary significantly among different populations,posing substantial challenges to the formulation and implementation of intervention strategies.Dynamically assessing the heterogeneity and disease progression trajectories of various groups is crucial.Latent class growth model(LCGM)serves as a statistical approach that fits a longitudinal data into N subgroups of individual development trajectories,identifying and analyzing the progression paths of different subgroups,thereby offering a novel perspective for disease control strategies.LCGM has shown significant advantages in the application of HIV/AIDS prevention and control,especially in gaining a deeper understanding and analysis of epidemiological characteristics,risk behaviors,psychological research,heterogeneity in testing,and dynamic changes.Summarizing the advantages and limitations of applying LCGM can provide a reliable basis for precise prevention and control of HIV/AIDS.

Objective To study the characteristics of invasive catheter infection in neurosurgery intensive care unit (NICU) to provide theoretical basis for the prevention of the infections.Method A retrospective analysis was done into the clinical data of 563 patients with indwelling catheter from January 2011 to December 2012 in our department.Results Among 563 cases undergoing invasive catheteration,there were 106 cases of catheter-associated infections with an incidence of 18.8%. The urinary catheter-associated infection was 24.5% and epidural drainage catheter-associated infection was 16.9%.Conclusion The enhanced consciousness of critical catheter infections,abiding by principles for aseptic operation and strengthened nursing to catheters or tubes are critical for reducing the incidence of invasive catheter-associated infections and ensuring the safety patients.
