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.

Objective The present study aimed to evaluate the clinical efficacy of hydraulic sinus floor elevation for the treatment of insufficient bone height in the posterior maxilla through a systematic review and Meta-analysis, so as to provide evidence for clinical practice. Methods Databases including PubMed, Embase, Cochrane Library, and Clinical Trials.gov were searched up to May 2025. Randomized controlled trials, non-randomized controlled trials, cohort studies, cross-sectional studies, and case-control studies that involved patients receiving hydraulic sinus floor elevation with simultaneous or delayed implant placement were included. Exclusion criteria comprised in vitro studies, animal experiments, narrative reviews, unpublished data, commentaries or expert opinions, studies with unclear sample sizes, and publications without full-text access or unavailable outcome data. Three investigators independently performed literature screening and quality assessment. A single-arm Meta-analysis was conducted using Stata 18.0 for studies meeting the inclusion criteria. The outcome measures were the incidence of sinus membrane perforation, implant survival rate, and endo-sinus bone gain. The Cochrane Risk of Bias 2 (RoB2) tool and the Joanna Briggs Institute (JBI) critical appraisal checklist were used to assess the methodological quality of randomized controlled trials and non-randomized controlled trials, respectively. The overall certainty of evidence was assessed using the GRADE（Grading of Recommendations Assessment, Development and Evaluation）system. Results Nineteen studies with 982 patients, 1 151 elevated sites, and 1 263 implants were finally included. The Meta-analysis showed that the intraoperative sinus membrane perforation rate of hydraulic sinus floor elevation was 2.0% [ES = 0.02, 95% CI (0.00, 0.04)] (18 studies, 1 061 sites); the implant survival rate was 99.0% [ES = 0.99, 95% CI (0.97, 1.00)] (17 studies, 1 253 implants); and the mean vertical bone gain was 7.80 mm. For this outcome, heterogeneity among studies was extremely high (I2 = 98.6%), thus only descriptive analysis was performed. Egger's test revealed no significant publication bias for the three outcomes. GRADE grading indicated very low certainty of evidence for mucosal perforation, implant survival rate, and endo sinus bone gain. Conclusion Current preliminary evidence suggests that hydraulic sinus lift may be a safe minimally invasive technique, but the evidence is very low, and more high quality, long term follow up randomized controlled clinical trials are still needed for further verification.

Objective:To investigate the molecular characteristics and clinical heterogeneity of Usher syndrome（USH） -related gene variants in patients with hereditary hearing loss in southwest China, providing a basis for early diagnosis and clinical management. Methods:Thirteen patients from twelve families with hearing loss who attended the Affiliated Children's Hospital of Kunming Medical University between January 2017 and March 2021 were enrolled. All patients were identified as carrying USH-related gene variants through next-generation sequencing. Sanger sequencing was performed for all patients and their parents to validate the pathogenic variants. Comprehensive clinical evaluations, including medical history collection, otologic and ophthalmologic examinations, and vestibular function assessments, were conducted. Results:Among the 13 patients, 4 were diagnosed with USH type 1 and 2 with USH type 2. A total of 19 pathogenic or likely pathogenic variants were detected in USH-related genes, including MYO7A,CDH23,USH1C, and USH2A. The causative gene was MYO7A in 3 probands, CDH23 in 5, USH1C in 3, and USH2Ain 2. All patients exhibited an autosomal recessive inheritance pattern. Vestibular dysfunction was observed in 4 patients, and retinitis pigmentosa（RP） in 3 patients. Based on the genotype-phenotype correlation, 6 patients were initially diagnosed with USH, while 7 were classified as having non-syndromic hearing loss（NSHL）. Conclusion:This study revealed the clinical heterogeneity of USH-related gene variants in patients with hereditary deafness in southwest China. Although the clinical manifestations of USH are complex and there are overlapping characteristics between different subtypes, genetic testing provides an important basis for early diagnosis and precise clinical management. Especially for those with typical hearing loss, early genetic diagnosis can provide a window of time for early detection and intervention of retinitis pigmentosa.

Inflammatory bowel disease (IBD) is an idiopathic intestinal inflammatory condition with chronic and relapsing manifestations and is characterized by a disturbance in the interplay between the intestinal microbiota, the gut, and the brain. The microbiota-gut-brain axis involves interactions among the nervous system, the neuroendocrine system, the gut microbiota, and the host immune system. Increasing published data indicate that psychological stress exacerbates the severity of IBD due to its negative effects on the microbiota-gut-brain axis, including alterations in the stress response of the hypothalamic-pituitary-adrenal (HPA) axis, the balance between the sympathetic nervous system and vagus nerves, the homeostasis of the intestinal flora and metabolites, and normal intestinal immunity and permeability. Although the current evidence is insufficient, psychotropic agents, psychotherapies, and interventions targeting the microbiota-gut-brain axis show the potential to improve symptoms and quality of life in IBD patients. Therefore, further studies that translate recent findings into therapeutic approaches that improve both physical and psychological well-being are needed.

Objective:To analyze the distribution and epidemiological characteristics of common non-bacterial pathogens in hospitalized children with acute respiratory tract infections(ARTI)from a multi-center study covering 4 regions in Fujian Province in 2023.Methods:A retrospective cohort study was conducted using medical record analysis.A total of 22 769 hospitalized children with ARTI were enrolled from January to December 2023 across seven regional pediatric medical centers in Fujian Province (covering four major geographical divisions of Fuzhou, Nanping, Sanming and Longyan; all selected hospitals were regional children′s medical centers).Using single-tube multiplex PCR with fragment analysis on a Sanger sequencing platform, the nucleic acids of 11 common non-bacterial respiratory pathogens were tested in nasopharyngeal swabs collected from 22 769 children. These pathogens included influenza A virus(FluA), influenza B virus(FluB), parainfluenza virus(PIV), respiratory syncytial virus (RSV), adenovirus (ADV), human rhinovirus (HRV), human bocavirus (HBoV), human coronavirus (HCoV), human metapneumovirus(HMPV), Mycoplasma pneumoniae(MP), and Chlamydia (Ch). Count data were described as [ n(%)], and the chi-square test/Fisher′s exact test was used to compare the differences in rates between groups. Epidemiological features, including positive detection rates, pathogen profiles, and correlations with region, sex, age and month, were analyzed. Results:Among 22 769 children with ARTI, pathogens were detected in 16 213 cases (71.21%), including 13 340 single infections (58.59%).The detection rates of single pathogens in descending order were human rhinovirus (HRV, 12.95%), Mycoplasma pneumoniae(MP, 12.27%), respiratory syncytial virus(RSV, 11.12%), influenza A virus (Flu-A, 7.98%), parainfluenza virus(PIV, 4.66%), human metapneumovirus(HMPV, 4.60%), adenovirus(ADV, 2.70%), human bocavirus(HBoV, 0.84%), human coronavirus(HCoV, 0.82%), influenza B virus(Flu-B, 0.47%) and Chlamydia(Ch, 0.18%).Mixed infections occurred in 2 873 cases(12.62%), primarily dual infections(2 679 cases).Regional analysis revealed significant disparities:Luoyuan County Hospital (Fuzhou) exhibited the highest total detection rate(86.59%, 1 414/1 633)and mixed infection rate(23.27%, 380/1 633)(both P<0.001), with notably elevated MP (26.39%, 431/1 633);Jian′ou City Hospital(Nanping) ranked second for Flu-A(14.21%, 409/2 879), RSV(13.20%, 380/2 879) and mixed infections(17.12%, 493/2 879);Lianjiang County Hospital(Fuzhou) showed distinct prevalence of Flu-A(10.68%, 130/1 217), PIV(6.00%, 73/1 217), and HBoV(1.73%, 21/1 217); Yong′an City Hospital (Sanming) reported high MP (26.07%, 238/913) and RSV(12.38%, 113/913);Shaowu City Hospital(Nanping) was dominated by MP (18.60%, 407/2 188) and HRV(13.39%, 293/2 188); Tingzhou Hospital(Longyan) had the highest HRV (17.88%, 407/2 276) and Flu-B (0.75%, 17/2 276); and Fuzhou Children′s Hospital showed elevated ADV(3.38%, 394/11 663) and HCoV(1.08%, 126/11 663). Except for Flu-B(0.47%, 108/22 769; P=0.054) and Ch(0.18%, 40/22769; P=0.900), all pathogens and mixed infections exhibited significant regional variations ( P<0.05).Gender analysis indicated higher detection rates of HRV, RSV, Flu-A, ADV, PIV, HBoV and mixed infections in males, while MP, HMPV, Flu-B, HCoV, and Ch were more prevalent in females, with statistically significant differences for HRV and MP (both P<0.001). Age stratification showed the highest overall detection rate in the 3-<6 years group (75.48%; P<0.001): RSV and Ch peaked in infants (<1 year), HRV, PIV, ADV and HBoV in toddlers (1-<3 years), HMPV, HCoV, and mixed infections in preschool children (3-<6 years), and MP, Flu-A and Flu-B in older children (6-<18 years).Analyzing the prevalent months, the monthly prevalence trends of pathogens in various regions are similar.Seasonal trends demonstrated year-round HRV activity (peaking in spring/autumn), MP prevalence in autumn/winter, RSV surges in spring-summer (April-June) and late summer-autumn (August-October), and Flu-A predominanced in winter-spring. Conclusion:Multiplex PCR with fragment analysis demonstrated high diagnostic efficacy. The top 4 non-bacterial pathogens in Fujian Province′s ARTI-hospitalized children in 2023 were HRV, MP, RSV and Flu-A. Pathogen distribution exhibited significant regional, age and seasonal variations, emphasizing the need for targeted prevention strategies.

Objective To evaluate the effectiveness and feasibility of a remote medication treatment management model for elderly patients with chronic disease at home based on mobile technology.Methods A convenient and elderly-friendly mo-bile application(hereinafter referred to as Yaoshiyi APP)was developed,and a remote medication treatment management team consisting of clinical pharmacists from tertiary hospitals,community pharmacists,and community physicians was formed.Patients from communities were selected for practical research,led by pharmacists.Based on the Yaoshiyi APP,patients were subjected to 6 months of medication treatment management practice,and the effectiveness and feasibility of the practice were evaluated.Re-sults The Yaoshiyi APP can be integrated with a variety of medical-grade wearable devices to realize the functions of automati-cally uploading monitoring data,abnormal value reminding,medication reminding,medication consultation,and medication sci-ence popularization.A total of 302 elderly patients with chronic disease at home completed the study.The results showed that phar-macists have identified and intervened in 695 cases of medication-related problems.According to the classification of medication-related problems,the top three were 247 cases(35.5％)of additional treatment,97 cases(14.0％)of unnecessary drug treat-ment,and 93 cases(13.4％)of medication compliance problems.The patient's medication adherence score(Morisky medication adherence scale-8,MMAS-8)increased from(5.85±1.57)at enrollment to(6.74±1.23)6 months after enrollment(P＜0.01).After 6 months of enrollment,the patient's satisfaction with the pharmacist's work reached a score of(4.99±0.08)out of 5.The average reduction in drug costs for patients caused by pharmacists intervening in irrational medication is(20.9±18.0)％.At the end of follow-up,93.4％of patients were proficient in using the Yaoshiyi APP.Conclusion The remote medication treatment management model for elderly patients with chronic disease at home based on mobile technology constructed in this study can ef-fectively improve patient compliance with disease monitoring and medication,ensure rational drug use,reduce medical resource waste,and receive high patient acceptance.

Objective To explore the diagnostic value of electrocardiogram parameters combined with serum microRNA(miR)-322 and miR-568 levels in patients with chronic heart failure(CHF)complicated with ventricular arrhythmias(VA).Methods A total of 230 CHF patients admitted to Zhangjiakou First Hospital from April 2020 to April 2023 were selected as the study objects,including 120 VA patients(VA group)and 110 non VA patients(non VA group),and 110 patients who underwent health examinations in Zhangjiakou First Hospital during the same period as the control group.Compared three sets of general information,electrocardiogram parameters,left ventricular ejection fraction(LVEF),cardiac function grade and serum miR-322 and miR-568 levels.Logistic regression analyzed the influencing factors of VA in CHF patients.Receiver operating characteristic curve(ROC)analyzed electrocardiogram parameters combined with serum miR-322 and miR-568 for the diagnostic value of VA in CHF patients.Results The three groups showed statistically obvious differences in classification of nyha heart function(NYHA)and left ventricular ejection fraction(LVEF)(F=6.033,691.853,all P<0.05).The electrocardiogram parameters of CHF patients,including QT interval dispersion(QTD),QRS wave duration and corrected QT systolic time(QTc)were obviously higher than those in the control group(t=16.539,17.709,14.414),and the VA group were obviously higher than the non VA group(q=10.984,7.794,10.174),and the differences were statistically significan(all P<0.05).The serum levels of miR-322 and miR-568 were obviously lower than those in the control group(t=23.719,17.359).and the VA group were obviously lower than the non VA group(q=10.345,9.941),the differences were statistically significant(all P<0.05).Logistic regression analysis showed that NYHA grading,LVEF,QTD,QRS,wave duration,QTc,serum miR-322 and miR-568 levels were all influencing factors in the complication of VA in patients with CHF(Wald χ2=4.267～9.839,all P<0.05).The combination of electrocardiogram parameters and serum miR-322,miR-568 was better diagnosing CHF patients with concurrent VA that QTD,QRS duration,QTc and serum miR-332,miR-568 were measured separately.Conclusion Serum levels of miR-322 and miR-568 are obviously reduced,and the combination of electrocardiogram parameters with serum miR-322 and miR-568 has high diagnostic value for CHF patients with VA.

Cantharidin(CTD),a natural compound used to treat multiple tumors in the clinic setting,has been limited due to acute kidney injury(AKI).However,the major cause of AKI and its underlying mechanism remain to be elucidated.Serum creatinine(SCr)and blood urea nitrogen(BUN)were detected through pathological evaluation after CTD(1.5 mg/kg)oral gavage in mice in 3 days.Kidney lipidomics based on ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS)was used to investigate lipids disorder after CTD exposure in mice.Then,spatial metabolomics based on matrix-assisted laser desorption/ionization-mass spectrometry imaging(MALDI-MSI)was used to detect the kidney spatial distribution of lipids.Integrative analysis was performed to reveal the spatial lipid disorder mechanism and verify key lipids in vitro.The results showed that the levels of SCr and BUN were increased,and tubular necrosis was observed in mouse kidneys,resulting in acute tubular necrosis(ATN)in CTD-induced AKI.Then,lipidomics results revealed that after CTD exposure,232 differential lipid metabolites and 11 pathways including glycerophospholipid(GP)and sphingolipid(SL)metabolism were disrupted.Spatial metabolomics revealed that 55 spatial differential lipid metabolites and nine metabolic pathways were disturbed.Subsequently,integrative analysis found that GP metabolism was stimulated in the renal cortex and medulla,whereas SL metabolism was inhibited in the renal cortex.Up-regulated lysophosphatidylcholine(LysoPC)(18∶2(9Z,12Z)),LysoPC(16∶0/0∶0),glycerophosphocholine,and down-regulated sphingomyelin(SM)(d18∶0/16:0),SM(d 18∶1/24:0),and SM(d42∶1)were key differential lipids.Among them,LysoPC(16∶0/0∶0)was increased in the CTD group at 1.1196 μg/mL,which aggravated CTD-induced ATN in human kidney-2(HK-2)cells.LysoPC acyltransferase was inhibited and choline phos-photransferase 1(CEPT1)was activated after CTD intervention in mice and in HK-2 cells.CTD induces ATN,resulting in AKI,by activating GP metabolism and inhibiting SL metabolism in the renal cortex and medulla,LysoPC(16:0/0:0),LysoPC acyltransferase,and CEPT1 may be the therapeutic targets.

AIM:To investigated the mechanism of action of Yiqi tongfu xiere prescription(YTX)in treating mice with lipopolysaccharide(LPS)-in-duced acute lung injury(ALI).METHODS:According to the random number table,24 C57BL/6 mice were divided into 4 groups:control group(Control),model group(LPS),low dose group(YTX-L)and high dose group(YTX-H).Except for the control group,the mice models of acute lung injury were established by intratracheal instillation of LPS solu-tion(5 mg/kg).The low and high dose treatment groups were given intragastric administration con-tinuously for 14 days.After 24 hours,the lung tis-sue,bronchoalveolar lavage fluid(BALF)and serum of the four groups were taken for follow-up detec-tion.The degree of pulmonary edema was evaluat-ed by wet weight coefficient(wet to dry ratio,W/D)of lung tissue.The degree of alveolar inflamma-tion and pulmonary fibrosis were evaluated by HE and Masson staining,and the contents of BALF and serum inflammatory cytokines IL-1β and IL-6 were detected by ELISA.The protein expressions of α-SMA,FN,Col-Ⅰ and Col-Ⅲ were measured by West-ern blot.Determination of α-SMA,FN,Col-Ⅰ,MAPK,NF-κB mRNA expression by RT-PCR method.RE-SULTS:Compared with LPS group,the contents of BALF,IL-1β and IL-6 in serum,Wmax D ratio,lung pathology,serum α-SMA,FN,Col-Ⅰ,Col-Ⅲ protein expression and α-SMA,FN,Col-Ⅰ,MAPK,NF-κB mRNA expression in treatment group were signifi-cantly lower than those in control group.CONCLU-SION:YTX can significantly reduce the levels of pul-monary fibrosis markers such as α-SMA,FN,Col-Ⅰand Col-Ⅲ by inhibiting the activation of MAPK/NF-κB signal pathway,and improve alveolar inflamma-tion and pulmonary fibrosis in mice with lung inju-ry,suggesting that YTX can treat acute lung injury and provide a theoretical basis for the clinical use of YTX.
