ObjectiveTo investigate the awareness and clinical practice of guidelines for the prevention and treatment of chronic hepatitis B （2022 edition） among clinicians. MethodsFrom July 19 to December 31， 2024， a self-designed electronic questionnaire was distributed via the WeChat mini program to collect related data from 1 588 clinicians nationwide， including their awareness and practice based on 18 questions regarding testing and referral， diagnosis and treatment， and follow-up. ResultsAmong all respondents， only 350 clinicians correctly understood all the updated key points of antiviral indications and treatment for special populations in the 2022 edition of guidelines for the prevention and treatment of chronic hepatitis B， with an overall awareness rate of 22.0%. Only 20% ‍—‍ ‍40% of the patients with positive HBV DNA and an age of >30 years receive antiviral therapy， while 80% ‍—‍ ‍100% of the patients with positive HBV DNA and a family history of hepatitis B cirrhosis or hepatocellular carcinoma receive antiviral therapy. The median follow-up rates at 1 year， 3 years， and 5 years were 67.5% 57.5% and 47.5%，respectively， showing a trend of gradual reduction， which might be associated with the influencing factors such as insufficient time for follow-up management by clinicians， insufficient awareness of the disease among patients， and poor adherence to follow-up. ConclusionThere is a gap between the awareness and practice of guidelines for the prevention and treatment of chronic hepatitis B （2022 edition） among clinicians. It is recommended to further strengthen training and focus on the whole process of “detection， diagnosis， treatment， and management” for patients with chronic hepatitis B in healthcare institutions， in order to promote the implementation of the guidelines.

Objective To investigate the accuracy and application value of the Tada formula in evalua-ting the meningioma volume based on 3D reconstruction technology.Methods The thin-slice magnetic reso-nance images of 297 patients with meningioma treated in the neurosurgery department of 940 Hospital of PLA Joint logistics Support Force from January 2014 to May 2022 were retrospectively analyzed.The meningioma volume was evaluated by the Tada formula method and three-dimensional reconstruction method respectively.The accuracy of the evaluation of meningeal tumor volume by the Tada formula was analyzed by grouping sta-tistics.Results In the whole sample and the concentrated sample,the obtained meningioma total volumes had no statistical difference between the two methods(P＞0.05),the Spearman correlation coefficients were 0.995 and 0.993 respectively,and the intragroup correlation coefficients(ICC)were 0.992 and 0.989,respec-tively.In the Bland-Altman plot,most of the data points were within the limit of uniformity.Compared with different groups,the Tada formula had a slightly lower accuracy in the volume assessment of meningiomas with higher degree of irregularity,and a better accuracy in the volume assessment of supratentorial meningio-mas than subtentorial meningiomas.Conclusion The Tada formula could accurately evaluate the volume of meningioma,and it could be used as a preliminary method to evaluate meningioma volume in clinic

Anticoagulation therapy stands as a key treatment for thrombotic diseases. The consequential bleeding risk tied to existing anticoagulation methods significantly impacts patient prognosis. In the intensive care unit (ICU), patients often necessitate organ support, leading to the inevitable placement of artificial devices in blood vessels, thereby requiring anticoagulation treatment to avert clot formation that might impede organ support. Nevertheless, these patients commonly encounter a heightened risk of bleeding. Hemophilia B, identified in 1953, manifests as a deficiency in coagulation factor Ⅺ (FⅪ), which focused people's perspective on the endogenous coagulation pathway, that is, the contact pathway. Upon interaction between the surface of artificial devices and FⅫ, FⅫ activates, subsequently triggering FⅪ and initiating the "coagulation cascade" within the contact pathway. Inhibitors targeting the contact pathway encompass two primary categories: FⅫ inhibitors and FⅪ inhibitors, capable of impeding this process. This article reviews the role of FⅫ and FⅪ in activating the contact pathway, seeking to illuminate their contributions to thrombus formation. By listing the relatively mature drugs and their indications, clinicians are familiar with this new anticoagulant.

Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.

Objective To analyze the clinical efficacy of transcatheter tricuspid valve replacement (TTVR) in cardiac implantable electronic lead-related tricuspid regurgitation (TR). Methods The patients with severe TR who underwent LuX-Valve TTVR in 9 Chinese medical centers from June 2020 to August 2021 were retrospectively enrolled. They were divided into a cardiac implantable electronic device (CIED) group and a non-CIED group based on whether they had pre-existing CIED implantation. Success of the procedure was defined as safe implantation of the LuX-Valve and complete withdrawal of the delivery system. Prognostic improvement was defined as a decrease of TR grade to≤2+ and an improvement of cardiac function by≥2 grades. Surgical success and postoperative prognosis were compared between the two groups. Results A total of 190 patients were collected, including 50 males and 140 females with a mean age of 66.2±7.8 years. There were 29 patients in the CIED group, and 161 patients in the non-CIED group. In the CIED group, 28 patients were implanted with a permanent pacemaker and 1 patient with a cardioverter-defibrillator. Preoperative New York Heart Association (NYHA) cardiac function class, TR degree, left ventricular ejection fraction, tricuspid annular plane systolic excusion, and cardiac risk scores were comparable between the two groups (P>0.05). Postoperative TR was reduced to≤2+ in all patients, and there was no statistical difference in the incidence of perivalvular leakage between the two groups (P=0.270). Postoperative CT of CIED patients showed the valve was in place, and the lead was not extruded, twisted, or deflected. The in-hospital mortality of the two groups were 10.3% and 1.9%, respectively, and the difference was statistically significant (P=0.047). In addition, there was no statistical difference between the two groups in terms of postoperative improvement of cardiac function and mortality in the 1- and 2-year follow-up. Conclusion TTVR is feasible, safe, and effective in patients with CIED implantation, and the pre-existing lead has no significant effect on the clinical efficacy.

OBJECTIVE To explore the effect and safety of dapagliflozin on cardiac function and renal function， blood glucose， and quality of life in patients with heart failure （HF） combined with chronic kidney disease （CKD）. METHODS A total of 156 patients with HF combined with CKD admitted to Shangqiu First People’s Hospital from January 1， 2021 to January 1， 2023 were included. According to the random number table， the patients were randomly divided into conventional treatment group （n＝80） and dapagliflozin group （n＝76）. Conventional treatment group was given conventional treatment； dapagliflozin group was additionally given Dapagliflozin tablets 10 mg orally， once a day， based on conventional treatment group. Both groups were treated for 6 months. Cardiac function [left ventricular ejection fraction （LVEF）， left ventricular end-systolic diameter （LVESD）， left ventricular end-diastolic diameter （LVEDD）， N-terminal pro-brain natriuretic peptide （NT-proBNP）]， renal function [blood creatinine， urea nitrogen， urinary albumin excretion rate （UAER）， glomerular filtration rate （GFR）， creatinine 806731979@qq.com clearance rate （CCR）]， glycosylated hemoglobin， and the quality of life were observed in 2 groups before and after treatment. The occurrence of ADR was recorded. RESULTS After treatment， LVESD， LVEDD， NT-proBNP， blood creatinine， urea nitrogen， UAER in 2 groups as well as the level of glycosylated hemoglobin in dapagliflozin group were significantly lower than before treatment； the dapagliflozin group was significantly lower than the conventional treatment group. LVEF， GFR， CCR and Kansas City Cardiomyopathy Questionnaire score were significantly higher than before treatment， and the dapagliflozin group was significantly higher than the conventional treatment group （P＜0.05）. There was no statistical significance in glycosylated hemoglobin of conventional treatment group before and after treatment （P＞ 0.05）. There was no statistically significant difference in the incidence of dizziness， rash， liver dysfunction， urinary system infection， new dialysis and hypotension between the two groups （P＞0.05）. CONCLUSIONS Dapagliflozin can improve the cardiac function and renal function of patients with HF complicated with CKD， improve patients’ quality of life and lower blood sugar levels without increasing the risk of adverse events.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

OBJECTIVE: To demonstrate the mechanism of mechanical ventilation (MV) induced endoplasmic reticulum stress (ERS) promoting mechanical ventilation-induced pulmonary fibrosis (MVPF), and to clarify the role of angiotensin receptor 1 (AT1R) during the process. METHODS: The C57BL/6 mice were randomly divided into four groups: Sham group, MV group, AT1R-shRNA group and MV+AT1R-shRNA group, with 6 mice in each group. The MV group and MV+AT1R-shRNA group mechanically ventilated for 2 hours after endotracheal intubation to establish MVPF animal model (parameter settings: respiratory rate 70 times/minutes, tidal volume 20 mL/kg, inhated oxygen concentration 0.21). The Sham group and AT1R-shRNA group only underwent intubation after anesthesia and maintained spontaneous breathing. AT1R-shRNA group and MV+AT1R-shRNA group were airway injected with the adeno-associated virus one month before modeling to inhibit AT1R gene expression in lung tissue. The expressions of AT1R, ERS signature proteins [immunoglobulin heavy chain-binding protein (BIP), protein disulfide isomerase (PDI)], fibrosis signature proteins [collagen I (COL1A1), α-smooth muscle actin (α-SMA)] in lung tissues were detected by immunofluorescence and Western blotting. Hematoxylin-eosin (HE) staining was used to evaluate lung injury and Masson staining was used to evaluate pulmonary fibrosis. RESULTS: Compared with the Sham group, the degree of pulmonary fibrosis and lung injury were more significant in the MV group. In the MV group, the protein expressions of AT1R, BIP, PDI, COL1A1 and α-SMA were increased (AT1R/β-actin: 1.40±0.02 vs. 1, BIP/β-actin: 2.79±0.07 vs. 1, PDI/β-actin: 2.07±0.02 vs. 1, COL1A1/α-Tubulin: 2.60±0.15 vs. 1, α-SMA/α-Tubulin: 2.80±0.25 vs. 1, all P < 0.01). The number of E-cad⁺/AT1R⁺ and E-cad⁺/BIP⁺ cells in lung tissue increased, and the fluorescence intensity of COL1A1 and α-SMA increased. Compared with the MV group, the degree of pulmonary fibrosis and lung injury were significantly relieved in the MV+AT1R-shRNA group. In the MV+AT1R-shRNA group, the protein expressions of AT1R, BIP, PDI, COL1A1 and α-SMA were decreased (AT1R/β-actin: 0.53±0.03 vs. 1.40±0.02, BIP/β-actin: 1.73±0.15 vs. 2.79±0.07, PDI/β-actin: 1.04±0.07 vs. 2.07±0.02, COL1A1/α-Tubulin: 1.29±0.11 vs. 2.60±0.15, α-SMA/α-Tubulin: 1.27±0.10 vs. 2.80±0.25, all P < 0.01). The number of E-cad⁺/AT1R⁺ and E-cad⁺/BIP⁺ cells in lung tissue decreased, and the fluorescence intensity of COL1A1 and α-SMA decreased. There was no statistically significant difference in the indicators between AT1R-shRNA group and Sham group. CONCLUSIONS MV up-regulate the expression of AT1R in alveolar epithelial cells, activate the AT1R pathway, induce ERS and promote the progression of MVPF.
