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.

Lysine-specific demethylase 1(LSD1)plays a regulatory role in tumor immunity.LSD1 affects CD8+T cell infiltration by regulating AGO2 protein level,and it is required for normal B cell proliferation and differentiation via reducing local chromatin accessibility.LSD1 inhibition promotes NK cell cytotoxicity of cancer cells through restoring the expression of ULBPs.LSD1 affects the resistance of M1 macrophages to oxidative stress by regulating the level of SOD2;In addition,regulating the expression of LSD1 affects the anti-tumor function of CD 19 CAR-T cells and immune checkpoint blockers.The development of drugs targeting LSD1 will provide new ideas for immunotherapy of tumors.

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.

Objective:To investigate the effect of CT-derived fractional flow reserve (CT-FFR) measurement sites on the values and the diagnostic performance, and to determine the optimal measurement site for CT-FFR using invasive FFR as the reference standard.Methods:This study was part of the CT-FFR CHINA clinical trial. Patients with suspected coronary artery disease who were scheduled for invasive coronary angiography (ICA) were prospectively recruited from five clinical centers across the country from November 2018 to March 2020. Each enrolled patient underwent coronary CT angiography (CCTA), CT-FFR, ICA, and invasive pressure wire-based FFR assessments sequentially within one week. Four groups of CT-FFR values were obtained on each enrolled target vessels according to different CT-FFR measurement locations: 1, 2, 3 cm distal to the target lesion, and terminal vessel groups. Spearman and Bland-Altman analyses were used to explore the correlation and consistency of CT-FFR values and FFR values at different measurement sites. The measurement deviation of CT-FFR was also compared. Diagnostic accuracy and performance of CT-FFR, including sensitivity, specificity, positive predictive value, negative predictive value, and area under the receiver operating characteristic curve (AUC), in discriminating myocardial ischemia were analyzed across all measurement site groups on a per-vessel level, using FFR as the reference standard.Results:A total of 289 patients with 345 target lesion vessels were included. According to CCTA, there were 51 target vessels (14.8%) with<50% stenosis, 106 vessels (30.7%) with 50%-69% stenosis, and 188 vessels (54.5%) with stenosis≥70%. At per-vessel level, CT-FFR and FFR values at each measurement position group were highly positively correlated: 1 cm distal to target lesion group, r=0.734 ( P<0.001); 2 cm distal to target lesion group, r=0.732 ( P<0.001); 3 cm distal to target lesion group, r=0.737 ( P<0.001); terminal vessel group was 0.719 ( P<0.001). At per-vessel level, CT-FFR and FFR values of all measurement sites were in good agreement (Bland-Altman analysis results): 1 cm distal to target lesion group, 0.014 (95% LoA 0.002-0.026); 2 cm distal to target lesion group, 0.026 (95% LoA 0.015-0.038); 3 cm distal to target lesion group, 0.040 (95% LoA 0.039-0.051); terminal vessel group, 0.075 (95% LoA 0.064-0.087). And at per-vessel level, the accuracy of diagnosing myocardial ischemia with CT-FFR at 1 cm was highest [84.6% (95% CI 80.4%-88.3%)], and the lowest accuracy in the terminal vessel group [67.0% (95% CI 61.7%-72.0%)]. However, there was no significant difference in the diagnostic accuracy of CT-FFR at 1 cm, 2 cm [80.6% (95% CI 76.1%-84.6%)] and 3 cm [77.5% (95% CI 72.6%-81.7%)]. AUC of CT-FFR at 1 cm distal to the lesion were both highest for global level and moderately stenosis (50%-69%) lesions [0.85 (95% CI 0.81-0.89), 0.84 (95% CI 0.77-0.90)]. And the differences were statistically significant among the four measurement location groups (all P<0.05). Conclusions:The deviation of CT-FFR increases with measurement site distance distal to target lesions. One centimeter distal to the target lesion is the optimal measurement site, and the CT-FFR value here shows the highest diagnostic performance for myocardial ischemic lesions, especially for moderate stenosis.

Objective To construct an evidence-based practice program of discharge preparation services for hip replacement patients based on the best evidence,and to evaluate its clinical effects,aiming to provide references for the implementation of relevant interventions.Methods Knowledge to Action Framework was used as a guide to summarise the best evidence on discharge preparation services for hip replacement patients and to select services based on clinical context.We selected 38 hip replacement patients and 17 healthcare professionals from the De-partment of Orthopaedic Surgery at a tertiary A hospital in Shanghai in September-October 2023 to conduct a baseline review,identify facilitating and hindering factors,and develop a practice protocol.We also selected 38 hip replacement patients and 17 healthcare professionals from November-December 2023 on this ward for evidence-based practice.Nurses'rates of completion of review indicators,levels of knowledge of discharge preparation ser-vices,and discharge planning competencies were compared before and after practice.Patients'readiness for dis-charge,hip function,and unplanned readmissions were also compared before and after the practice.Results After evidence-based practice,nurses'completion rates of review indicators,knowledge of discharge preparation services,and discharge planning competencies were higher than baseline levels(P＜0.05).Hip replacement patients showed a significant improvement in readiness for discharge and hip function(P＜0.001).Conclusion The implementation of an evidence-based practice program of discharge preparation services improves nurses'knowledge and skills,and also contributes to the discharge readiness and hip function of hip replacement patients.

Focusing on the management needs of retired personnel in hospitals,this paper analyzes the issues present in traditional management methods,such as delayed data updates,low information sharing efficiency,and high management costs.It emphasizes the importance of digital information management in enhancing the efficiency and quality of services for retired per-sonnel.By highlighting the advantages of digital management in terms of systematicity,convenience,and accuracy,a preliminary model of a digital information management system for retired hospital personnel was developed.An in-depth analysis of 1 846 re-tired personnel's composition,system usage behaviors,and management performance showed that within six months of system im-plementation,the number of visits exceeded 8 600.The electronic archive replacement rate increased from 23.5％ to 96.2％ ,and satisfaction rates rose from 74.2％ to 91.6％ ,confirming the value of digital management in improving efficiency and service experience.Despite these successes,challenges remain,such as untimely data updates,difficulties for retirees in using the sys-tem,and inadequate privacy protection measures.To address these issues,strategies such as enhancing data sharing,regularly organizing skills training and operational guidance,and establishing robust data security management protocols are proposed.These measures aim to improve management efficiency and accuracy while safeguarding system security and retirees'rights.By implementing these strategies,hospitals can better meet the diverse service needs of retirees and further advance management in-formatization and scientific development.

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.

Objective:To investigate the correlation between remnant cholesterol/high-density lipoprotein cholesterol ratio (RC/HDL-C) and metabolic dysfunction-associated fatty liver disease (MAFLD) in health check-up population.Methods:It was a cross-sectional study. A total of 5 299 subjects who received physical examination in the Health Management Center of Renmin Hospital of Wuhan University from January to December in 2023 and met the admission criteria were selected as the research subjects. The subjects were examined by demography, anthropometry, laboratory tests and liver instantaneous elastography. The Chi-square test, t-test, one-way analysis of variance, Mann-Whitney U test and Kruskal-Wallis H test were used to compare the indexes between the subjects with and without MAFLD. The subjects were divided into 4 groups (Q1-Q4 groups) according to the RC/HDL-C ratio quartiles by quartile method, and the indexes in each group were compared. The receiver operating characteristic (ROC) curves were drawn using MedCalc software and compared to assess the diagnostic efficacy of the RC/HDL-C ratio for MAFLD. Results:With the increase of RC/HDL-C ratio, the detection rate of MAFLD (12.56% vs 43.48%), male proportion (55.68% vs 85.60%), total cholesterol (TC) [(4.63±0.82) vs (5.10±1.06) mmol/L], triglyceride (TG) [0.90(0.71, 1.15) vs 2.58(1.96, 3.50) mmol/L], alanine aminotransferase (ALT) [17.00(13.00, 24.00) vs 26.00(19.00, 38.00) U/L], aspartate aminotransferase (AST) [20.00(17.00, 24.00) vs 23.00(19.00, 29.00) U/L], and controlled attenuation parameter (CAP) [(239.32±40.52) vs (274.60±44.98) dB/m] increased gradually, while high-density lipoprotein cholesterol (HDL-C) [1.40(1.20, 1.64) vs 0.93(0.84, 1.04) μmol/L] decreased gradually (all P<0.05). ROC curves showed that the AUC value of RC/HDL-C ratio was significantly higher in identifying MAFLD when compared with TC, HDL-C, LDL-C, non-HDL-C and RC (AUC=0.676, P<0.05). Conclusions:The RC/HDL-C ratio is positively correlated with the risk of morbidity of MAFLD in health check-up population.
