OBJECTIVE To conduct a comprehensive clinical evaluation of four nucleoside （acid） analogues that have been approved and marketed in China， such as entecavir， tenofovir disoproxil fumarate， tenofovir alafenamide fumarate， and tenofovir amibufenamide. METHODS According to the Guideline for the Administration of Clinical Comprehensive Evaluation of Drugs （2021 edition， trial implementation）， a comprehensive search was conducted across databases including CNKI， Wanfang Data， VIP， PubMed， the Cochrane Library， Embase， as well as relevant official websites. Drug package inserts， guidelines， consensus statements， and relevant literature for the four drugs were collected and subjected to a comprehensive evaluation across six dimensions： safety， efficacy， cost-effectiveness， innovativeness， suitability， and accessibility. RESULTS The scores for entecavir in terms of safety， efficacy， cost-effectiveness， innovativeness， suitability， and accessibility-along with its comprehensive score-were 13， 14， 13， 10， 18， and 6， totaling 74 points. For tenofovir disoproxil fumarate， the respective scores were 13， 17， 18， 8， 18， and 7， totaling 81 points. For tenofovir alafenamide fumarate， the scores were 14， 20， 12， 8， 18， and 5， totaling 77 points. Finally， for tenofovir amibufenamide， the scores were 10.5， 17， 10， 6， 15， and 4， totaling 62.5 points. CONCLUSIONS Tenofovir disoproxil fumarate， with the highest score， is recommended as the first-line option， suitable for adults， children， and pregnant women. However， caution is warranted for potential renal impairment. Tenofovir alafenamide fumarate is recommended as a second-line alternative， particularly for individuals at high risk for bone and renal damage. Entecavir has a score similar to tenofovir alafenamide fumarate but requires dosing on an empty stomach and dose adjustment based on renal function of patients. Tenofovir amibufenamide received the lowest score and is considered a weak recommendation. The clinical application of these nucleoside （acid） analogues should be individualized based on the patient’s age， physiological status， and risk factors.

ObjectiveTo evaluate the clinical efficacy of Shenqi Yangxin decoction in the treatment of ischemic cardiomyopathy （ICM） with Qi and Yin deficiency and blood stasis syndrome and its effect on serum hydrogen sulfide （H₂S） and calcium ion （Ca²⁺）. MethodsA total of 64 ICM patients with Qi and Yin deficiency and blood stasis syndrome who met the inclusion criteria were randomly divided into a control group （n=32） and a treatment group （n=32）. All patients received conventional Western medicine treatment. The treatment group was additionally given Shenqi Yangxin decoction. The TCM syndrome score， Minnesota Living with Heart Failure Questionnaire （MLHFQ） score， left ventricular ejection fraction （LVEF）， N-terminal pro-B-type natriuretic peptide （NT-proBNP）， 6-minute walk test （6MWT）， New York Heart Association （NYHA） cardiac function classification， and serum H₂S and Ca²⁺ levels were compared between the two groups pre- and post-treatment. ResultsTwo cases dropped out from each group during the study. Finally， 30 patients in each group were included in the analysis. There were no significant differences in age， gender， course of coronary heart disease， underlying diseases， and laboratory tests between the two groups. Compared with baseline， the TCM syndrome score， MLHFQ score， and NT-proBNP in both treatment group and control group decreased significantly （P<0.01）， LVEF， 6MWT， and H₂S increased significantly （P<0.01）， and serum Ca²⁺ increased （P<0.05）. Compared with the control group after treatment， the MLHFQ score and NT-proBNP in the treatment group decreased （P<0.05）， the TCM syndrome score decreased significantly （P<0.01）， LVEF， 6MWT， and serum Ca²⁺ increased （P<0.05）， and H₂S increased significantly （P<0.01）. The improvement degree of the NYHA cardiac function classification in the treatment group was higher than that in the control group， but there was no significant difference. ConclusionShenqi Yangxin decoction is effective in treating ICM patients with Qi and Yin deficiency and blood stasis， which could significantly improve cardiac function and quality of life， and its therapeutic effect may be related to the regulation of serum H₂S and Ca²⁺ levels.

ObjectiveTo analyze the incidence and spatiotemporal distribution of typhus fever in Baoshan City, Yunnan Province from 2005 to 2023, to identify high-risk populations and regions, so as to provide a scientific basis for optimizing the allocation of local prevention and control resources and developing targeted intervention measures. MethodsData of typhus fever cases in Baoshan City from 2005 to 2023 were obtained from the Infectious Disease Information Management System of the Chinese Center for Disease Control and Prevention. Descriptive epidemiological methods were used to analyze the temporal, spatial and demographic distribution of typhus fever cases. Spatial clustering was assessed using spatial dynamic window scan statistics (circular and elliptical windows), flexible spatial scan statistics, and local spatial autocorrelation methods (including local Moran’s I, local Geary’s C, and Getis-Ord G_i*). Retrospective spatiotemporal scan statistics were employed to detect spatiotemporal clusters. ResultsA total of 1 099 typhus fever cases were reported in Baoshan City from 2005 to 2023. The incidence rate peaked at 6.31/ 100 000 in 2007, followed by a decline until reaching its lowest level at 0.21/100 000 in 2015 , and subsequently rebounded during 2016‒2023. The highest proportion of cases was among children under 10 years of age (31.12%), and the top three occupations of cases were farmers, students, and children, accounting for 88.62% of all cases. Cases occurred predominantly between June and September each year. The incidence was relatively high in Jiucheng Town (62.58/100 000), Yaoguan Town (57.15/100 000), and Dianyang Town (46.81/100 000) of Shidian County. Spatial clustering analyses indicated that high-risk areas were mainly located in the southern part of Baoshan City, showing a south-to-north trend. Spatiotemporal scan analyses identified five clusters, with the most likely cluster centered around Yaoguan Town, covering ten towns (subdistricts) during the period 2007‒2010. ConclusionThe incidence of typhus fever in Baoshan City exhibits a clear seasonal and spatial clustering pattern, with peak incidence occurring in summer and autumn. Spatially, cases are primarily distributed in the southern part of Baoshan City, and high-risk clusters exhibit a south-to-north trend. Farmers, students, and children are the high-risk groups.

Multiple system atrophy （MSA） is a rare degenerative disease of the nervous system and has diverse and atypical clinical manifestations， and it overlaps with other diseases in α-synuclein spectrum disease. There are great challenges in the diagnosis and early differential diagnosis of the disease， and missed diagnosis and misdiagnosis occur from time to time， thereby delaying the treatment of the disease.Videonystagmography （VNG） is currently the main noninvasive test used to assess vestibular function and can provide different eye movement parameters. Studies have shown the presence of abnormal eye movements in patients with MSA. From the perspective of vision-eye movement， this article reviews the current status of research on eye movements in patients with MSA and reveals the internal connection between them， in order to provide an important reference for the early diagnosis of MSA.

Hepatocellular carcinoma （HCC） is a common malignant tumor with a high mortality rate， an insidious onset， and complex pathological mechanisms. In the tumor microenvironment， tumor-promoting immune cells protect tumor cells from immune attacks， while dysfunction of anti-tumor immune cells causes the inhibition of immune response， thereby leading to the continuous deterioration of cancer. In recent years， traditional Chinese medicine has shown good efficacy in the treatment of HCC， and it can inhibit the proliferation and metastasis of cancer cells by regulating immune cells. By analyzing related articles in China and globally， this article summarizes how immune cells affect the progression of HCC through the immunosuppressive pathway and how traditional Chinese medicine exerts an anti-HCC effect by regulating immune cells， in order to provide theoretical basis and reference for optimizing the treatment of HCC.

Objective To evaluate the application value of the MR three-dimensional double inversion recovery(3D DIR)sequence in the diagnosis of optic neuritis(ON).Methods A retrospective analysis was conducted on MRI images from 40 patients with sus-pected ON.All patients underwent conventional T2 WI fat suppression(FS)and 3D DIR sequences.The lesion detection rate and diag-nostic accuracy of the intraorbital,intracanalicular,and intracranial segments of the optic nerve were compared between the two sequences,respectively.The receiver operating characteristic(ROC)curves were used to assess the diagnostic performance,and the intraclass correlation coefficient(ICC)were used to analyze interobserver consistency.Imaging assessments were independently performed by two senior and two junior radiologists.Results The sensitivity(SEN),specificity(SPE),and accuracy(ACC)in lesion detection of 3D DIR sequence were significantly better than those of conventional T2 WI FS sequence[odds ratio(OR)221 vs 104,P＜0.001].Notably,3D DIR sequence exhibited superior performance in detecting lesions in the intraorbital segment[area under the curve(AUC)0.915,OR=102]and intracanalicular segment(AUC 0.858,OR=51)compared with conventional T2WI FS sequence.Additionally,3D DIR sequence significantly improved diagnostic consistency among junior radiologists(ICC value increased from 0.469 to 0.655),bring-ing their diagnostic performance closer to that of senior radiologists(AUC improved to 0.883,ACC reached 90.1％).Conclusion The 3D DIR sequence has outstanding diagnostic efficacy in detecting ON lesions,significantly improving ACC and interobserver consistency,thereby offering strong support for the precise diagnosis of ON.

Objective To systematically evaluate and integrate qualitative studies on perception of exercise behaviors in community-dwelling older adults with frailty,and to provide references for clinical development of targeted exercise intervention strategies.Methods A systematic search of PubMed,Medline,Embase,PsycINFO,the Cochrane Library,SinoMed,Wanfang Database,CNKI,and VIP Database for qualitative studies on perception of exercise behaviors in older adults with frailty in the community was conducted from the inception of the databases to June 2024.Literature quality was evaluated using the Australian Joanna Briggs Institute Centre for Evidence-Based Health Care Quality Assessment Criteria for Qualitative Research(2016 edition),and Meta-synthesis was performed using the theme synthesis method.Results A total of 10 papers were included,grouped into 10 categories and integrated into the 3 domains of the capability,opportunity,and motivation-behavior model(COM-B model),i.e.Preparation for exercise behavior is influenced by capability factors(physical reserve,knowledge reserve,psychological preparation);stage-specific motivational evolution promotes the internalization of exercise behavior(guiding,focusing,stimulating,and maintaining);external conditions provide opportunities for exercise behavior(individual interaction,community environment,and social support).Conclusion Perceptions of exercise behavior among community-dwelling older adults with frailty or are complex and influenced by a variety of factors.Future exercise intervention strategies should consider modifiable factors,enhance knowledge education,stimulate intrinsic motivation,and solidify external conditions,while also accommodating individual differences and preferences,so as to promote exercise participation and health enhancement in this group.

Objective:To analyze the prevalence of chronic kidney disease (CKD) and influencing factors of adults in Hebei Province, and provide scientific evidence for the development of comprehensive CKD prevention and control strategies.Methods:In China Adult Chronic Disease and Nutrition Surveillance in Hebei in 2018, a total of 7 562 permanent residents aged ≥18 years were selected by multi-stage stratified cluster random sampling from 13 surveillance points in Hebei for questionnaire survey, medical examination and laboratory test.Results:A total of 1 067 CKD patients were detected in the adults aged ≥18 years in this survey, with a weighted prevalence rate of 12.10%. The results of multivariate analysis showed that the daily total static behavior time ( OR=1.07, 95% CI: 1.04-1.09), living in rural area ( OR=1.50, 95% CI: 1.14-1.97), coal use ( OR=1.37, 95% CI: 1.16-1.61), coal gas/liquefied gas/natural gas/biogas use ( OR=2.92, 95% CI: 2.40-3.54) and solar energy/electricity use ( OR=1.75, 95% CI: 1.36-2.25), insufficient fruit intake ( OR=1.39, 95% CI: 1.06-1.83), insufficient physical activity ( OR=1.35, 95% CI: 1.11-1.64), suffering from hypertension ( OR=1.80, 95% CI: 1.44-2.24) and suffering from diabetes ( OR=1.77, 95% CI: 1.27-2.45) were risk factors for CKD in adults in Hebei. High education level ( OR=0.41, 95% CI: 0.19-0.91), excessive drinking ( OR=0.53, 95% CI: 0.28-0.99), central obesity ( OR=0.75, 95% CI: 0.58-0.97), history of allergic diseases ( OR=0.44, 95% CI: 0.27-0.72) were protective factors for CKD. Conclusions:The prevalence of CKD in adults in Hebei was relatively high, especially in those who had too long average daily static behavior, lived in rural area, used coal, gas/liquefied gas/natural gas/biogas, solar energy/electricity, had inadequate intake of fruits, lacked physical activity and suffered from hypertension and diabetes. It is necessary to pay attention to the early prevention and treatment of CKD, strengthen the health education about healthy lifestyle and improve the management of patients with chronic disease, such as hypertension and diabetes, to further reduce the risk for CKD.

Objective:To develop the Discharge Readiness Scale for Patients with Chronic Skin Wounds and evaluate its reliability and validity.Methods:The Discharge Readiness Scale for Patients with Chronic Skin Wounds was developed through literature review, semi-structured interviews, Delphi expert consultation, and a pre-survey. Convenience sampling was employed to select 320 patients with chronic skin wounds hospitalized at Chongming Hospital, Shanghai University of Medicine and Health Sciences and Qingdao Municipal Hospital from June 2023 to December 2024 for formal investigation, conducting scale reliability and validity analysis. The critical ratio method and correlation coefficient method were used for project analysis. Content validity of the scale was assessed using item-level content validity index and average scale-level content validity index, and construct validity was evaluated through exploratory factor analysis and confirmatory factor analysis. Reliability analysis employed Cronbach's α coefficient.Results:A total of 320 questionnaires were distributed, and 304 valid questionnaires were collected, with a valid response rate of 95.0%. The average scale-level content validity index was 0.91, and the item-level content validity index ranged from 0.80 to 1.00. Exploratory factor analysis revealed that the cumulative variance contribution rate of the five common factors was 67.483%. The overall Cronbach's α coefficient for the scale was 0.831. The final constructed scale comprised five dimensions of trajectory stage cognition, wound self-care skills, symptom management, psychosocial adaptation, and health information acquisition and resource utilization, with a total of 26 items.Conclusions:The Discharge Readiness Scale for Patients with Chronic Skin Wounds demonstrates good reliability and validity, providing clinical healthcare professionals with a standardized assessment tool.
