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.

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.

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.

ObjectiveTo investigate the pathogenic spectrum and epidemiological characteristics of diarrheal disease in Fengxian District of Shanghai, and to provide scientific basis for the prevention and control of diarrheal diseases. MethodsBasic information of the initial adult cases visited diarrheal disease surveillance sentinel hospital in Fengxian District, Shanghai, was collected from August 2013 to 2023, and fecal samples were collected at 1∶5 sampling intervals to isolate and identify 5 kinds of diarrheagenic Escherichia coli (DEC), Salmonella (SAL), Vibrio parahaemolyticus, Campylobacter, Vibrio cholerae, Shigella and Yersinia enterocolitica (YE). Simultaneously, nucleic acid detection was performed for 3 kinds of rotavirus, 2 kinds of norovirus, intestinal adenovirus, astrovirus and sapovirus. ResultsA total of 1 861 cases of newly diagnosed diarrheal disease were reported, with the peak in July to August. Additionally, 704 surveillance samples were detected, with a total positive detection rate of 50.57%. The detection rates of bacterial, viral and mixed infection were 25.14%, 21.02% and 4.40%, respectively. Among the pathogens detected, DEC accounted for the highest (17.61%, 124/704), followed by norovirus (16.48%, 116/704), rotavirus (6.39%, 45/704), SAL (5.97%, 42/704) and Campylobacter (3.84%, 27/704). DEC detected were mainly enteroaggregative Escherichia coli and enterotoxigenic Escherichia coli, with no detection of Vibrio cholerae, Shigella and YE. The highest total pathogen detection rate was observed from June to September, and the detection peaks of norovirus were from March to June and from October to December, whereas that of DEC was from June to October. The detection rate of rotavirus peaked from January to February, but which was not detected between 2020‒2023. The SAL positive rate peak was in September, whereas that of Campylobacter was from July to September. ConclusionThe main pathogens detected in Fengxian District from 2013‒2019 are DEC, norovirus, rotavirus, SAL and Campylobacter. Different pathogens have different detection peaks, with bacteria predominating in summer and viruses in winter and spring. Prevention and control measures should be carried out according to the epidemiological characteristics of different seasons.

Objective To investigate the clinical efficacy of Qi Shi Shen Shu Capsule combined with dapagliflozin in treating type 2 diabetic nephropathy.Methods 120 patients with type 2 diabetic nephropathy(qi-yin liangxu syndrome)admitted to the endocrinology department in the inpatient and outpatient depart-ments of endocrinology from May 2022 to December 2023 were randomly divided into control and observation groups(60 cases each).The control group received dapagliflozin plus placebo capsules,while the observation group received dapagliflozin plus Qi Shi Shen Shu Capsule for 6 months.The therapeutic effects were observed between the two groups.Parameters including serum creatinine(Scr),urinary albumin-to-creatinine ratio(uACR),24-hour urinary protein quantification(24hUP),glycated hemoglobin(HbA1c),and tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),and high sensitivity-C reactive protein(hs-CRP)were measured be-fore and after treatment.Results The total effective rate was higher(P＜0.05)in the observation group(93.33％)than in the control group(78.33％).After treatment,both groups showed decreased levels of uACR,Scr,24hUP,HbA1c,TNF-α,IL-6,and hs-CRP compared with baseline,with lower levels in the obser-vation group(P＜0.05).Conclusion Qi Shi Shen Shu Capsule combined with dapagliflozin can effectively re-duce uACR,Scr levels and serum inflammatory cytokines levels in patients with type 2 diabetic nephropathy.

Objective To explore the effects of single-session table tennis exercise with different intensities on working memory and the associated cognitive neural processing mechanisms in college students with depressive symptoms by using event-related potential(ERP)technology.Methods A convenience sampling approach was employed to recruit 100 college students with depressive symptoms from a university.Participants were randomly assigned at a 1∶1∶1∶1 ratio to low-intensity exercise group,moderate-intensity exercise group,high-intensity exercise group,or control group.The exercise groups participated in a single 30-min table tennis intervention at intensities corresponding to 57%-64%of maximum heart rate(HRmax)and rate of perceived exertion(RPE)scores ranging from 9-11,65%-75%HRmax and RPE scores 12-13,and 76%-95%HRmax and RPE scores of 14-17(5-min warm-up,20-min monitored exercise,5-min cool-down).The control group did not receive any exercise intervention.Pre-and post-intervention assessments of verbal working memory(VWM)and spatial working memory(SWM)were performed,alongside the recording of ERP components,including the amplitude and latency of N2 and P3,during the tasks.Results A total of 91 participants(20 in the low-intensity exercise group,25 in the moderate-intensity exercise group,23 in the high-intensity exercise group,and 23 in the control group)were enrolled for analysis.In the VWM task,the main effect of time on accuracy was found to be significant(F(1,89)=5.942,P=0.017,partial η2=0.064).Post-intervention,accuracy was significantly improved in the moderate-intensity and high-intensity exercise groups(change=0.027,95%confidence interval[CI]0.001-0.053,P=0.037;change=0.029,95%CI 0.002-0.055,P=0.040).The main effect of time on reaction time was also significant(F(1,89)=7.244,P=0.009,partial η2=0.077).The interaction between group and time was also significant(F(3,87)=2.844,P=0.042,partial η2=0.089).After the intervention,the reaction time was reduced in the low-intensity and moderate-intensity exercise groups(change=-0.095,95%CI-0.183--0.007,P=0.035;change=-0.079,95%CI-0.158-0,P=0.049).The interaction between time and electrode location in the P3 latency in ERP components was significant(F(3,87)=5.785,P＜0.001,partial η2=0.062),while the interactions for other ERP measures were not significant(all P＞0.05).In the SWM task,the main effect of time on accuracy was significant(F(1,89)=5.092,P=0.027,partial η2=0.055),while the interaction between group and time was not significant(F(3,87)=0.799,P=0.498,partial η2=0.027).After the intervention,accuracy was improved in the moderate-intensity exercise group(change=0.019,95%CI 0-0.037,P=0.046).The main effect of time on reaction time was significant(F(1,89)=14.322,P＜0.001,partial η2=0.141).The interaction between group and time was not significant(F(3,87)=1.521,P=0.215,partial η2=0.050).After the intervention,reaction time was shortened in the moderate-intensity and high-intensity exercise groups(change=-0.082,95%CI-0.136--0.027,P=0.004;change=-0.075,95%CI-0.131--0.018,P=0.029).The interaction between time and electrode location in the P3 amplitude in ERP components was significant(F(3,87)=5.475,P=0.001,partial η2=0.059),while the interactions for other ERP measures were not significant(all P＞0.05).Conclusion Single-session table tennis exercise with different intensities has a positive effect on working memory in college students with depressive symptoms.Moderate-to high-intensity exercise can enhance VWM accuracy,while low-to moderate-intensity exercise can reduce VWM reaction time.Furthermore,moderate-intensity exercise can improve SWM accuracy,and moderate-to high-intensity exercise can shorten SWM reaction time.Additionally,high-intensity exercise can lead to greater activation of ERP components.

Objective:To analyze the relationship among thyroid autoimmunity (TAI), thyroid function, and gestational diabetes mellitus (GDM) in early pregnant women in Xi'an.Methods:A prospective study included pregnant women who underwent prenatal check-ups at the Northwest Women's and Children's Hospital from November 2020 to October 2021, with a gestational age of 6 to 14 weeks. Thyroid function, thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TgAb), and urinary iodine levels were measured, and the prevalence of thyroid disease and GDM was monitored. The subjects were divided into four groups: TPOAb positive only, TgAb positive only, both TPOAb and TgAb positive, and both TPOAb and TgAb negative, to compare the differences in the prevalence of thyroid disease and GDM among the groups. Statistical analysis was performed using Kruskal-Wallis rank-sum test, Bonferroni correction, Chi-square test, and a multivariate logistic regression model was used to analyze the relationship between TAI, thyroid disease, and GDM. Results:A total of 20 243 early pregnant women were included in this study, among which 1 615 (7.98%) were positive for TPOAb only; 865 (4.27%) were positive for TgAb only; 1 672 (8.26%) were positive for both TPOAb and TgAb (both positive group); and 16 091 (79.49%) were negative for both TPOAb and TgAb (both negative group). The thyroid stimulating hormone levels in the TPOAb positive only group, TgAb positive only group, and both positive group were significantly higher than those in the both negative group, respectively (Bonferroni correction, all P<0.05); the free thyroxine level in the TPOAb positive only group was significantly lower than that in the both negative group ( P<0.05). After adjusting for age, pre-pregnancy body mass index, and urinary iodine levels, multivariate logistic regression analysis showed that compared to the both negative group, the risk of developing hypothyroidism during pregnancy was significantly increased in the both positive group ( OR=11.49, 95% CI: 2.84-46.39); the risk of developing subclinical hypothyroidism during pregnancy was significantly increased in the TgAb positive only group ( OR=1.99, 95% CI: 1.05-3.76) and the both positive group ( OR=3.74, 95% CI: 2.49-5.63); the risk of developing GDM was significantly increased in the TgAb positive only group ( OR=1.43, 95% CI: 1.04-1.96) and the both positive group ( OR=1.94, 95% CI: 1.53-2.46). Among early pregnant women with normal thyroid function, after adjusting for age, pre-pregnancy body mass index, and urinary iodine levels, multivariate logistic regression analysis showed that compared to the both negative group, the risk of developing GDM was significantly increased in the TgAb positive only group ( OR=1.46, 95% CI: 1.06-2.02) and the both positive group ( OR=1.80, 95% CI: 1.40-2.32). Conclusion:TgAb positive only is a risk factor for subclinical hypothyroidism and GDM. Screening for thyroid autoantibodies, especially TgAb, during pregnancy helps in the early identification of high-risk pregnant women for thyroid dysfunction and GDM.

Alzheimer's disease(AD)is an age-related neurodegenerative disease with an increasing incidence worldwide.A large number of studies have shown that the incidence rates of hearing loss is high in patients with mild cognitive impairment and Alzheimer's disease,and may be a risk factor for the occurrence and development of cognitive impairment.There is an interaction between the two,but the causal mechanism is still unclear.Early screening and management of hearing impairment may play an important role in the early diagnosis,symptom im-provement and disease progression of Alzheimer's disease.This paper reviews relevant clinical and basic research to discuss the correlation between hearing loss and Alzheimer's disease,and the possible causal mechanism between them.
