Background/Aims: This study assessed the long-term efficacy and safety of tenofovir alafenamide (TAF) in real-world settings. Methods: Patients who were candidates for TAF treatment and were followed up at 12-week intervals over 192 weeks were enrolled in this study. Results: One hundred and forty-four patients (50 treatment-naive and 94 treatment-experienced) were included in this study. The cumulative incidence rates of cirrhosis and hepatocellular carcinoma at 192 weeks were 3.9% and 0.7%, respectively. In treatment-naive patients, the rates of a virological response, HBeAg conversion, and HBsAg loss at 192 weeks were 100%, 33.3%, and 2%, respectively. The treatment-naive patients exhibited higher baseline HBsAg levels than the treatment-experienced patients (4.31 log10IU/mL vs. 3.97 log10IU/mL). A significant decrease in the HBsAg levels from the baseline was observed at 144 and 192 weeks in the treatment-naive patients (p=0.01). The baseline body mass index (BMI) <25 kg/m2 (p=0.02) and HBsAg <3.3 log10IU/mL (p=0.04) were identified as predictive factors for a decrease in HBsAg ≥0.5 log10IU/mL at 48 weeks. The eGFR levels were consistently lower in the treatment-experienced patients throughout the study. Although the treatment-naive patients showed no abnormal increases in urinary URBP, the treatment-experienced patients showed elevated urinary β2MG and NAG levels at the baseline, which decreased over the treatment course. The total cholesterol, triglyceride, and low-density lipoprotein levels were similar in both groups. Conclusions Prolonging the TAF treatment duration enhances the virological response rate. The decline in HBsAg levels was more significant in the treatment-naive patients than in the treatment-experienced patients. The baseline BMI <25 kg/m2 and HBsAg <3.3 log10IU/mL were predictive factors for a significant decline in HBsAg at 48 weeks. TAF has high renal safety and no significant impact on lipid levels.

Objective To explore potential categories of post-stroke depression in acute-phase stroke patients and its correlation with the degree of neurological deficits,and to provide references for healthcare professionals in developing targeted interventions.Methods Using convenience sampling,patients with acute stroke who were hospitalized in neurological ward of 2 tertiary general hospitals in Henan Province from January to April 2024 were selected as the survey participants.The investigation was conducted using the General Information Questionnaire,the National Institute of Health Stroke Scale,and the Patient Health Questionnaire-9.The correlation between potential categories of post-stroke depression and the degree of neurological deficit was analysed using unordered multiclassified logistic regression.Results Post-stroke depression score was 10.22±3.61 in 193 acute-phase stroke patients,and post-stroke depression could be categorized into 3 potential categories,namely"low depressive symptoms"(44.6％),"melancholic depression"(15.0％),and"atypical depression"(40.4％).There was a significant difference in the degree of neurological deficits(H=38.074,P＜0.001).Compared with severe neurological deficits,patients with mild deficits were more likely to be categorized as"melancholic depression"(OR=0.016,P=0.001)and"atypical depression"(OR=0.040,P＜0.001),and patients with moderate deficits were more likely to be classified as"atypical depression"(OR=0.085,P=0.001).Conclusion Post-stroke depression in acute-phase stroke patients has obvious categorization characteristics,and it is recommended that healthcare professionals should pay more attention to patients with different degrees of neurological deficits and adopt targeted interventions according to the different categories of post-stroke depression in order to alleviate their depressive symptoms.

The integration of medical treatment and disease prevention(hereinafter referred to as"med-prevent integra-tion")constitutes a vital strategy for achieving universal health objectives.Party-building initiatives in university-affiliated hospi-tals present a novel approach to enhance this integration at the primary care level.This study identifies three major challenges in current practice,including insufficient conceptual integration between medical and preventive services,inadequate cross-depart-mental coordination and resource allocation,and imperfect accountability mechanisms within Party-building frameworks.From the perspective of integrated governance,we propose a comprehensive pathway where party-building facilitates the systematic conver-gence of ideological orientation,organizational structure,cultural values,and institutional mechanisms.These findings provide both theoretical framework and practical guidance for university-affiliated hospitals to deepen primary-level med-prevent integration through Party-building initiatives.

Objectives:To provide a new perspective on the epidemiological characteristics of vertebral column fracture in China and to guide the formulation of targeted public health strategies.Methods:The Global Burden of Disease 2021 database was utilized to analyze the epidemiological trends of vertebral column fracture in China from 1990 to 2021.The study further explored the disease burden characteristics related to age,sex,and etiology.The Joinpoint regression model was employed to calculate the average annual percent change(AAPC)to analyze the temporal trends of age-standardized rates.The Bayesian age-period-cohort(BAPC)model was used to forecast the age-standardized rates for 2035.Results:In 2021,the incidence and prevalence of vertebral column fracture in China were 1194465[95％uncertainty interval(UI):888994-1594120]and 717078(95％UI:619114-835347),respectively,representing increases of 52.28％and 113.66％compared to 1990.From 1990 to 2021,the age-standardized incidence rate(ASIR)in China showed no significant upward trend,with an AAPC of 0.45％[95％confidence interval(CI):-0.29％to 1.20％,P＞0.05],while the age-standardized prevalence rate(ASPR)showed a significant upward trend,with an AAPC of 0.53％(95％CI:0.24％to 0.83％,P＜0.05).The BAPC prediction results for 2022-2035 indicated a downward trend for both ASIR and ASPR.Analysis by age group revealed that the peak age groups for incidence and preva-lence have increased,with the crude incidence rate(CIR)and crude prevalence rate(CPR)increasing with age,reflecting an aging trend.Gender analysis found that the disease burden was more prominent among middle-aged men and elderly women.Etiological analysis revealed that falls were the leading cause of spinal frac-tures in China,followed by road injuries.Conclusions:From 1990 to 2021,the disease burden of spinal fractures in China has significantly increased and shown an aging trend.Although the predicted disease bur-den for 2035 is expected to decline,it is still necessary to remain vigilant.Middle-aged men and elderly women are the key populations of concern,and emphasis should be placed on preventing falls and road in-juries.

Objective:To evaluate the clinical efficacy, safety and treatment persistence of upadacitinib in Crohn's disease (CD) patients.Methods:The single-center retrospective cohort study was conducted. The patients with moderate-to-severe active CD initiating upadacitinib therapy from November 2023 to November 2024 in Nanjing Drum Tower Hospital were collected through searching the electronic medical records and paper-based patient databases. The primary outcome was the clinical remission rate at week 12. Secondary outcomes included the clinical response rate at week 12; clinical response and remission rates at weeks 4, 24 and 48; biomarker (fecal calprotectin or C-reactive protein) remission rates at all time points; as well as endoscopic remission and response rates, treatment persistence and safety evaluation.Results:A total of 44 CD patients were included, comprising 24 males (54.5%) and 20 females (45.5%). The median age was 33 (25, 40) years. The baseline Crohn's disease activity index (CDAI) score was 260.5 (225.9, 550.0) points. Patients had previously received a median of 2 (1, 2) biologic treatments. All 44 patients completed the 12-week induction therapy. With a median follow-up of 30.00 (16.25, 46.25) weeks, the clinical remission rate was 50.0% (22/44) at week 12. The clinical remission rate, clinical response rate, and biomarker remission rate were 52.3% (23/44), 88.6% (39/44) and 72.7% (32/44) respectively at week 4, and the clinical response rate and biomarker remission rate were 88.6% (39/44) and 77.2% (34/44) respectively at week 12. The clinical remission rates, clinical response rates and biomarker remission rates evolved to 43.3% (13/30), 86.7% (26/30) and 80.0% (24/30) at week 24, and further to 44.4% (4/9), 77.8% (7/9) and 77.8% (7/9) at week 48. During the follow-up period, 13 CD patients completing endoscopic evaluation, endoscopic remission and response rates were 30.8% and 23.1% respectively. CD-related surgery rate was 4.5% (2/44). Safety analysis demonstrated that the overall adverse events rate was 56.8% (25/44) including 7 patients with serious adverse events. A total of 8 patients discontinued treatment, among which 3 were due to primary loss of response, 1 due to secondary loss of response, 2 due to drug-related adverse events alone, and 2 due to concurrent primary loss of response and adverse events. The Kaplan-Meier curve for treatment persistence showed that among 39 CD patients who achieved clinical response at week 12, the continued treatment rates were 90.3% at week 12 and 85.3% at week 24 of follow-up. Two patients (5.6%) received dose escalation of upadacitinib, both of whom achieved clinical remission.Conclusion:Real-world research data demonstrate that upadacitinib exhibits significant clinical efficacy and a favorable safety profile in the treatment of moderate-to-severe active CD patients with prior biologic exposure, and no new unexpected adverse events are identified.

N6-methyladenosine(m6A)is the most common mRNA modification in eukaryotes,and fat mass and obesity-related protein(FTO),are its demethylases,which efficiently remove the modification of m6A mRNA,and is strongly associated with obesity.Atherosclerosis is a chronic inflammatory lesion of the blood vessel wall driven by lipids.It was found that FTO-mediated m6A may influence the process of atherosclerosis through lipid metabolism,oxidative stress,mitochondrial dysfunction,and macrophage foaminess.

Objective:To observe the effect of different degrees of decentration and tilt on the optical quality of the intraocular lenses (IOLs) with different focus designs.Methods:The UV 3300 PC UV-visible spectrophotometer was employed to measure the spectral transmittance of the monofocal IOL CT ASPHINA 509M (509M), bifocal IOL AT LISA 809M (809M), and trifocal IOL AT LISA Tri 839MP (839MP) within Zeiss MICS platform with a refractive power of + 20 D. The modulation transfer function (MTF) values at a spatial frequency of 50 lp/mm along with MTF curves and United States Air Force (USAF) resolution test charts for each IOL at the focal point were measured at apertures of 3.0 mm and 4.5 mm using the in vitro optical quality testing system OptiSpheric IOL R&D under centered, decentered (0.3, 0.5, 0.7, 0.9 and 1.1 mm) and tilted (3°, 5°, 7°, 9° and 11°) conditions. Results:All three IOLs filtrated the ultraviolet (UV) spectrum below 400 nm.When each IOL was in the centered position, at the 3.0 mm aperture, the MTF values were 0.772 at the far focus of the monofocal IOL 509M, 0.467 and 0.282 at the far and near focus of the bifocal IOL 809M, and 0.416, 0.147, and 0.229 at the far, intermediate, and near focus of the trifocal IOL 839MP, respectively.Whereas at the 4.5 mm aperture, the monofocal IOL 509M MTF value at the far focus was 0.664, the bifocal IOL 809M MTF values at the far and near focus were 0.506 and 0.264, and the trifocal IOL 839MP MTF values at the far, intermediate, and near focus were 0.392, 0.107, and 0.210, respectively.Among the three centered IOLs, the 509M demonstrated the highest MTF value at the far focus, followed by the 809M and then the 839MP; at the near focus, the MTF value of the 809M surpassed that of the 839MP.For decentration and tilt, the difference in MTF values of the three IOLs at the far and near focus was consistent with the differences observed when they were centered.At the same degree of decentration and tilt, all three IOLs exhibited superior optical quality at the 3.0 mm aperture compared to the 4.5 mm aperture.The optical quality of all three IOLs exhibited an overall decline as decentration and tilt increased.All three IOLs demonstrated a decrease in optical quality at the decentration of 0.3 mm or the tilt of 5°.Conclusions:The IOLs within the Zeiss MICS platform design exhibits identical spectral transmittance and UV filtering properties.Among the three IOLs, when centered, the 509M, the 839MP, and the 809M exhibit superior optical quality at the far, intermediate, and near focal points, respectively.Under decentered and tilted conditions, the 509M and the 809M demonstrate better resistance against decentration and tilt, respectively, at both far and near focuses.Additionally, all three IOLs demonstrate better optical quality at smaller apertures, given equivalent degrees of decentration or tilt.However, the optical quality at each focal point of the three IOLs decreases compared to the centered position when subjected to a decentration of 0.3 mm or a tilt of 5°.

Dental implantology has developed rapidly for over half a century,since pure titanium(99.7％)dental cylindrical threaded implants were exploited and osseointegration was introduced in 1960s by Prof.Br?nemark.The long term retention rates of 10 years or more are over 95％.However,the biological complications jeopardize the long term effects of dental implant treatment seriously.The prevalence of dental implant biological complications varies greatly among different reports resulting from the disparities on the defini-tions of dental implant biological complications.After analyzing and summarizing the major opinions proposed internationally in recent years,the consensus for the definition of dental implant biological complications has been reached.Generally the dental implant biologi-cal implications can be classified into early stage(before restoration)biological complications and late stage(after restoration)biological complications.The early stage biological complications include acute and chronic infections,pain,soft tissue deficiency,and osseointegration failure,etc.The late stage complications include peri-implant diseases(peri-implant mucositis and peri-implantitis),soft tissue deficiency around implant,implant loosening and dropping off,etc.The various risk factors related to different dental implant biological complications,the strategies of the prevention and treatment for the dental implant biological complications have been discussed comprehensively,and the consensus has been reached.It is aimed to advocate the dentist to pay more attention to the early prevention of the biological implant complications,to promote more researches on the implant biological complications,and to help elevate the level of dental implantology in our country.

BACKGROUND:Current treatment strategies for chronic non-healing wounds have shown unsatisfactory results,necessitating the exploration of novel therapeutic approaches.Concentrated growth factors,rich in high-concentration growth factors and possessing a stable natural three-dimensional structure,have demonstrated significant application value in the treatment of chronic non-healing wounds.OBJECTIVE:To review the current status of concentrated growth factor application in chronic non-healing wounds,analyze the shortcomings of concentrated growth factor in clinical applications,and propose constructive suggestions and prospects.METHODS:CNKI,WanFang,and VIP databases were searched with the key words of"concentrated growth factor,platelet concentrate products,chronic wound,chronic ulcer,wound healing,platelet-rich plasma,platelet-rich fibrin"in Chinese.PubMed was searched with the key words of"CGF,concentrated growth factor,platelet concentrate products,chronic wound,chronic ulcer,wound healing,PRP,PRF,platelet-rich plasma,platelet-rich fibrin"in English.The articles published from 2000 to 2024 were searched and further analyzed and summarized after screening.RESULTS AND CONCLUSION:Concentrated growth factor,with its diverse application forms,high concentration of growth factors,natural three-dimensional structure,compatibility with various material technologies,relatively low cost,and ease of operation,has demonstrated significant clinical value in the treatment of chronic wounds.Numerous researchers have validated its positive effects in chronic wound therapy through clinical applications.However,there is currently no clear consensus on standardized concentrated growth factor application protocols,and certain deficiencies have been revealed in practical applications,including issues with dosage,centrifugation settngs,identification schemes,and preparation methods for different forms of concentrated growth factor.There is substantial room for research on concentrated growth factor,and it is believed that with a clear consensus on its application in the future,concentrated growth factor could play a significant role in clinical practice.

Objective:To study the correlation between iodine level in drinking water and conventional water quality indicators.Methods:From June 2017 to July 2018, a simple random sampling method was used to select administrative villages (communities) from 88 counties (cities, districts) in Guizhou Province with a sampling size greater than 5%. One drinking water sample was collected from each administrative village (community), and conventional water quality indicators (including fluorine, aluminum, mercury, selenium, sulfate, total dissolved solids and total hardness) were tested in accordance with the methods outlined in the "Standards for Drinking Water Quality" (GB 5749-2006). The cerium sulfate catalytic spectrophotometric method was employed to test drinking water iodine level. Spearman method was utilized to analyze the correlation between iodine level in drinking water and conventional water quality indicators.Results:A total of 904 drinking water samples were tested, with a median iodine level of 1.90 μg/L and a range of 0.10 - 36.70 μg/L. There were 899 administrative villages (communities) with a water iodine level of less than 10 μg/L, accounting for 99.45%. There were only 5 administrative villages (communities) with a water iodine level of greater than 10 μg/L, accounting for 0.55%. Correlation analysis revealed that in Guizhou Province, the iodine level in drinking water was positively correlated with the levels of fluorine, aluminum, sulfate, total dissolved solids, and total hardness [correlation coefficients ( r) = 0.11, 0.07, 0.07, 0.08, 0.07, P < 0.05], and was a negatively correlated with mercury and selenium levels ( r = - 0.12, - 0.12, P < 0.001). Conclusions:External environment in Guizhou Province is generally deficient in iodine. The iodine level in drinking water is positively correlated with the levels of fluorine, aluminum, sulfate, total dissolved solids, and total hardness, and negatively correlated with the levels of mercury and selenium.
