Objective To evaluate the significance of serum 8-hydroxy-deoxyguanosine acid ( 8-OHdG) in the diagnosis of nonalcoholic steatohepatitis ( NASH).Methods Patients or healthy subjects were enrolled at the Second Hospital of Tianjin Medical University and the Second People ′s Hospital of Tianjin from May 2013 to December 2015.A total of 41 patients with nonalcoholic fatty liver disease were enrolled in the study , including 20 nonalcoholic simple fatty liver ( NAFL) patients and 21 NASH patients whose diagnosis were proven by liver biopsy.The other 32 healthy subjects were studied as controls.Serum 8-OHdG, ALT, AST and GGT were tested.Nonalcoholic fatty liver disease activity score ( NAS ) and expression of 8-OHdG in liver was investigated between NAFL patients and NASH patients.The correlations between serum 8-OHdG and serum ALT , AST, GGT, and 8-OHdG in liver tissue in NASH group were investigated.In addition , the receiver operating characteristic ( ROC) curve analyses for ALT and 8-OHdG levels were performed in NAFL patients and NASH patients , and the cut-off value was determined.Results Serum 8-OHdG values in healthy controls , NAFL and NASH patients were (0.19 ±0.16) μg/L, (0.22 ±0.16) μg/L, (0.42 ±0.21) μg/L respectively.The serum 8-OHdG and serum ALT, GGT and 8-OHdG in liver tissue were all positively correlated in NASH group with respective correlation coefficient r values as 0.454 7, 0.382 9, and 0.497 6.AUC of 8-OHdG was 0.901 with cut-off value 0.39 μg/L.Its sensitivity was 88.3%and specificity was 81.5%, which were higher than those of ALT.Conclusion The value of serum 8-OHdG would be used as a marker for the diagnosis of NASH.

Objective:To investigate the clinical application of cognitive behavioral therapy (CBT) and the reasons of the choosing CBT.Method:Totally 14 psychotherapists accepted a semi-structured interview,including their backgrounds of CBT training,the application of CBT in psychotherapy,their attitude toward consultative relations,their opinion on comparing other schools with CBT,and their reasons for choosing CBT.Results:The main reasons for choosing CBT included the influence of important others,the characters of CBT and personal factors.In clinical practice,the most commonly used behavioral techniques included exposure therapy,roll play,relaxation Waining and so on.The most commonly used cognitive techniques included Socratic questioning,cognitive restructuring and challenge unreasonable cognition.Conclusion:Cognitive behavioral therapy (CBT) is suitable for those who are sensible and preferring structural therapy.Nevertheless,the trend in therapy is the integration of different psychotherapy schools.

Objective:To explore the facilitators and barriers in implementing the orthokeratology lens-wearing education guidance program from the perspectives of children, their families, and medical and nursing staff.Methods:Based on phenomenological research, purposive sampling was used to select five medical workers, 18 children wearing orthokeratology lenses and family members from the Optometry Center of Peking University Third Hospital as interviewees for semi-structured interviews. Colaizzi's 7-step method was used to analyze interview data.Results:Two themes (facilitators and barriers) were extracted, among which facilitators included two sub-themes (strong demand for educational guidance, trust in medical and nursing staff), and barriers consisted of two sub-themes (patient factors, external support factors) .Conclusions:In promoting the educational guidance intervention program for wearing orthokeratology lenses, medical and nursing staff need to fully play the role of facilitators, analyze and solve barriers, and ultimately promote the smooth implementation of the intervention program.

Falls among the elderly are a serious public health problem. This paper reviews the application status of machine learning in fall risk identification, fall prevention training intervention, fall behavior detection and warning, analyzes the advantages and disadvantages of machine learning in the field of fall risk management for the elderly, and aims to provide ideas for personalized and accurate fall prevention practice for the elderly in the future.

Over the past few years, the human virome and its complex interactions with microbial communities and the immune system have gained recognition as a crucial factor in human health. Individuals with compromised immune function encounter distinctive challenges due to their heightened vulnerability to a diverse range of infectious diseases. This review aims to comprehensively explore and analyze the growing evidence regarding the role of the virome in immunocompromised disease status. By surveying the latest literature, we present a detailed overview of virome alterations observed in various immunodeficiency conditions. We then delve into the influence and mechanisms of these virome changes on the pathogenesis of specific diseases in immunocompromised individuals. Furthermore, this review explores the clinical relevance of virome studies in the context of immunodeficiency, highlighting the potential diagnostic and therapeutic gains from a better understanding of virome contributions to disease manifestations.
