Objective To investigate the changes of serum cathepsin L(CTSL)in patients with acute exacerbation of chronic heart failure(CHF)and its relationship with lipid metabolism and severity of the disease.Methods A prospective study was conducted on 186 elderly patients with acute exacerbation of CHF admitted to our hospital from February 2021 to October 2024.Their serum levels of CTSL and lipid metabolism indicators were measured at admission.According to the quartile of CTSL,they were divided into groups A(CTSL≤3.31 μg/L,47 cases),B(3.31μg/L＜CTSL≤3.70 μg/L,46 cases),C(3.70 μg/L＜CTSL＜4.41 μg/L,47 cases),and D(CTSL≥4.41 μg/L,46 cases).The general clinical data,blood lipid metabolism and severity of disease were compared among the four groups.Pearson correlation analysis was used to analyze the correlation between CTSL and blood lipid metabolism indicators,and ordinal regression model and restricted cubic spline analysis was employed to examine the relationship between serum CTSL and the se-verity of acute exacerbation of CHF.Results There were significant differences in total cholester-ol(TC),triglyceride(TG),high density lipoprotein cholesterol(HDL-C)and low density lipopro-tein cholesterol(LDL-C)among the four groups of patients(P＜0.05,P＜0.01).Pearson correla-tion analysis showed that serum CTSL level was positively correlated with TC,TG and LDL-C levels(r=0.203,P=0.005;r=0.178,P=0.015;r=0.184,P=0.012),and negatively with HDLC(r=—0.344,P=0.000).Ordinal regression analysis indicated that serum CTSL level was an inde-pendent risk factor affecting the severity of CHF in patients with acute exacerbation(P＜0.05).Restricted cubic spline analysis revealed that serum CTSL level was in a linear relationship with the severity of acute exacerbation of CHF(x2=3.140,P=0.371).When serum CTSL＞3.73μg/L,the severity of the condition was increased significantly.Conclusion Serum CTSL level is closely associated with lipid metabolism in elderly patients with acute exacerbation of CHF,and is an independent risk factor for the severity of disease.

Background:To compare the efficacy and safety of monthly administrations of gonadotropin releasing hormone (GnRH) agonists LY01005 and Zoladex ? in Chinese patients with premenopausal breast cancer. Methods:From October 2020 to November 2021, 188 premenopausal breast cancer patients were enrolled in 34 hospitals and randomized 1:1 to receive either LY01005 or Zoladex ? every 28 days for a total of three injections. All patients concomitantly received oral tamoxifen (TAM). The primary efficacy endpoint was cumulative probability of maintaining menopausal level [oestradiol (E2) ≤30 pg/ml] from day 29 to day 85. The second efficacy endpoint included changes in E2, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) compared with the baseline. Pharmacokinetics (PK), pharmacodynamics (PD), and safety were analyzed. The study also evaluated the pharmacokinetic and pharmacodynamic characteristics of LY01005. Results:A total of 188 patients were randomised and 187 patients received either LY01005 or Zoladex ?. Cumulative probabilities of maintaining menopausal level (E2≤30 pg/ml) from day 29 to day 85 were 93.1% for LY01005 and 86.3% for Zoladex ?. The between-group difference was 6.8% (95% CI: -2.3%, 15.9%) and primary efficacy in the LY01005 group was not inferior to that in the Zoladex ? group. Changes in E2, LH, and FSH levels compared with the baseline were equivalent between the two groups (E2: 89.34% to 90.23% vs. 82.11% to 85.02%; LH: 88.89% to 95.52% vs. 89.70% to 97.02%; FSH: 75.36% to 80.85% vs.73.07% to 80.24%, respectively). After three consecutive doses of LY01005, the LH and FSH levels of the subjects showed a transient increase after the first dose, reached a peak on the second day and then started to decrease. The LH and FSH reached a lower level and remained at or below that level until the 85th day. Both treatments were well-tolerated. Conclusion:LY01005 is as effective as Zoladex ? in suppressing E2 to menopausal levels in Chinese patients with premenopausal breast cancer, with a similar safety profile.

Objective:To investigate the feasibility of the bortezomib, lenalidomide, and dexamethasone (VRD) regimen combined with autologous hematopoietic stem cell transplantation (auto-HSCT) in patients with multiple myeloma (MM) and renal impairment, analyze treatment efficacy and renal responses stratified based on renal dysfunction severity, and explore the prognostic significance of early renal response and its affecting factors.Methods:This retrospective study, conducted at the First Affiliated Hospital of Soochow University, categorized 316 patients with newly diagnosed MM (NDMM) from August 2018 to October 2022 based on renal function for analysis of clinical characteristics, treatment response, and prognosis. Continuous variables were compared using t-tests or Mann-Whitney U tests, categorical variables utilizing Chi-square tests, survival outcomes employing Kaplan-Meier and Log-rank tests, and renal response predictors with logistic regression.Results:Patients were stratified based on baseline estimated glomerular filtration rate (eGFR) : normal [≥90 ml·min -1· (1.73 m 2) -1, n=160], mild [≥60 ml·min -1· (1.73 m 2) -1 to <90 ml·min -1· (1.73 m 2) -1, n=55], moderate [≥30 ml·min -1· (1.73 m 2) -1 to <60 ml·min -1· (1.73 m 2) -1, n=39], and severe impairment [<30 ml·min -1· (1.73 m 2) -1, n=62]. Moderate and severe renal impairment correlated with advanced International Staging System/Revised International Staging System classification, lower hemoglobin levels, frailty, and higher light-chain/IgD subtype prevalence ( P<0.05). Despite younger age ( P=0.001) and higher transplant rates ( P=0.041) in severe cases, overall response rates ( ORR: 93.7% ; ≥VGPR: 82.9% ) were comparable across groups ( P>0.05). Among 24 dialysis-dependent patients at diagnosis, 11 (45.8% ) achieved dialysis independence after induction [median: 3.0 (0.5–4.0) months], including 10 undergoing auto-HSCT. In 89 evaluable patients [baseline eGFR <50 ml·min -1· (1.73 m 2) -1], renal ORR (RORR) was 70.8% [rapid complete response: 31.5% ; rapid partial response: 11.2% ; rapid minimal response (RMR) : 28.1% ]. Renal response predicted better survival (overall survival: HR=0.36, 95% CI: 0.13–0.99, P=0.049). Moderate-to-severe renal impairment was associated with increased transplant-related adverse events and delayed engraftment ( P<0.05) ; however, auto-HSCT significantly improved outcomes after 33.5-month median follow-up (range: 2–65 months). Multivariate analysis identified 1q21+ ( OR=3.58, 95% CI: 1.17–11.02, P=0.026) and light-chain subtype ( OR=2.86, 95% CI: 1.08–7.69, P=0.036) as independent predictors of poor renal response. Conclusion:VRD regimen plus auto-HSCT demonstrates robust efficacy in NDMM, including patients with renal impairment, with a 70.8% RORR and manageable toxicity. Achieving ≥RMR correlates with superior prognosis, whereas 1q21+ and light-chain subtype independently predict inferior renal response.

Transient receptor potential vanilloid-1(TRPV1) channel is a non-selective ligand-gated cationic channel with multiple activation mechanisms in the transient receptor potential subfamily. In recent years, a large number of studies have found that TRPV1 plays an important role in the field of cardiovascular diseases such as hypertension and atherosclerosis. With the in-depth study of traditional Chinese medicine, it has been found that Chinese medicine monomers and their active components can activate or inhibit TRPV1 channels, which has certain potential in the study of cardiovascular diseases. In this paper, the role of TRPV1 channel in cardiovascular diseases and the research progress of traditional Chinese medicine prevention and treatment of cardiovascular diseases based on TRPV1 channel are reviewed, in order to provide new ideas for prevention and treatment of cardiovascular system diseases.

Objective:To learn about the age, period, birth cohort characteristics, and incidence trends of hemorrhagic fever with renal syndrome (HFRS) nationwide.Methods:HFRS monitoring data from 2004 to 2018 were collected from the National Public Health Science Data Center (https://www.phsciencedata.cn/). The trend of incidence rate of HFRS was analyzed by joinpoint regression, and the linear trend was estimated by annual percentage change (APC) and average annual percentage change (AAPC). Bayesian Age-Period-Cohort (BAPC) analysis of the effects of age, period, and birth cohort on HFRS cases was conducted, with age, period, and birth cohort used as reference for the 40 - 44 age group, 2011, and 1968, respectively, the RR and 95% CI were calculated. Results:From 2004 to 2018, a total of 190 197 HFRS cases were reported nationwide, with an average annual incidence rate of 0.95/100 000. Among them, the highest incidence rate of HFRS was 1.93/100 000 in 2004. Since 2007, it had continued to fluctuate below 1.00/100 000, ranging from 0.66/100 000 to 0.99/100 000. Joinpoint regression fitting results showed that the overall incidence of HFRS in China was declining (AAPC = - 7.33%, 95% CI: - 8.07% - - 6.58%, P < 0.001); the APCs from 2004 to 2007, 2007 to 2009, and 2012 to 2016 were - 32.00%, - 8.74%, and - 9.02%, respectively, all showed a downward trend( P < 0.05); the APCs from 2009 to 2012 and from 2016 to 2018 were 14.69% and 11.38%, respectively, both showed an upward trend ( P < 0.05). HFRS cases were reported in all age groups, and the reported incidence rate showed a unimodal distribution with age. Among them, the highest incidence rate was in the 50 - 54 age group (1.75/100 000), and the lowest incidence rate was in the 0 - 4 age group (0.03/100 000); the proportion of cases in the age group of 60 years and above increased from 9.75% in 2004 to 25.90% in 2018, showed an increasing trend year by year (χ 2trend = 9 210.90, P<0.001). The analysis results of the BAPC model showed that in the age effect analysis, compared with the reference age group, there was no significant difference in the incidence risk among the age groups of 15 - 79 years old ( P > 0.05), while the incidence risk was lower in the age groups of 14 years old and below, and 80 years old and above ( RR < 1, P < 0.05). In the analysis of period effects, compared with the reference year, the incidence risk was higher from 2004 to 2006 and from 2012 to 2014 ( RR > 1 , P < 0.05), and lower from 2008 to 2010 and from 2017 to 2018 ( RR < 1, P < 0.05); the overall trend was consistent with the descriptive analysis of onset period. In the analysis of birth cohort effect, compared with the reference cohort, the population born between 1920 - 1935 and 1970 - 2018 had lower incidence risk ( RR < 1, P < 0.05); but the risk of disease in the population born after 2003 showed an upward trend. Conclusions:The HFRS epidemic in China has decreased from 2004 to 2018, but the downward trend in recent years is not significant. The incidence risk has increased among people born after 2003. The population aged 60 and above is a key group for further controlling the HFRS epidemic in China.
