Objective:To investigate the clinical features and prognosis of male with anti-melanoma differentiation-associated gene 5 (MDA5) autoantibody.Methods:The clinical data of 246 patients with DM and anti-MDA5 autoantibodies hospitalized by Jiangsu Myositis Cooperation Group from 2017 to 2020 were collected and retrospectively analyzed. Chi-square test was performed to compared between counting data groups; Quantitative data were expressed by M ( Q1, Q3), and rank sum test was used for comparison between groups; Single factor survival analysis was performed by Kaplan-Meier method and Log rank test; Cox regression analysis were used for multivariate survival analysis. Results:①The male group had a higher proportion of rash at the sun exposure area [67.1%(47/70) vs 52.8%(93/176), χ2=4.18, P=0.041] and V-sign [50.0%(35/70) vs 30.7%(54/176), χ2=8.09, P=0.004] than the female group. The male group had higher levels of creatine kinase [112(18, 981)U/L vs 57 (13.6, 1 433)U/L, Z=-3.50, P<0.001] and ferritin [1 500 (166, 32 716)ng/ml vs 569 (18, 14 839)ng/ml, Z=-5.85, P<0.001] than the female group. The proportion of ILD [40.0%(28/70) vs 59.7%(105/176), χ2=7.82, P=0.020] patients and the red blood cell sedimentation rate[31.0(4.0, 101.5)mm/1 h vs 43.4(5.0, 126.5)mm/1 h, Z=-2.22, P=0.026] in the male group was lower than that of the female group, but the proportion of rapidly progressive interstitial lung disease (PR-ILD) [47.1%(33/70) vs 31.3%(55/176), χ2=5.51, P=0.019] was higher than that of the female group. ②In male patients with positive anti-MDA5 antibodies,the death group had a shorter course of disease[1.0(1.0, 3.0) month vs 2.5(0.5,84) month, Z=-3.07, P=0.002], the incidence of arthritis [16.7%(4/24) vs 42.2%(19/45), χ2=4.60, P=0.032] were low than those in survival group,while aspartate aminotransferase (AST)[64(22.1, 565)U/L vs 51(14,601)U/L, Z=-2.42, P=0.016], lactate dehydrogenase (LDH) [485(24,1 464)U/L vs 352(170, 1 213)U/L, Z=-3.38, P=0.001], C-reactive protein (CRP) [11.6(2.9, 61.7) mg/L vs 4.95(0.6, 86.4) mg/L, Z=-1.96, P=0.050], and ferritin levels [2 000(681, 7 676) vs 1 125 (166, 32 716)ng/ml, Z=-3.18, P=0.001] were higher than those in the survival group, and RP-ILD [95.8%(23/24) vs 22.2%(10/45), χ2=33.99, P<0.001] occurred at a significantly higher rate. ③Cox regression analysis indicated that the course of disease LDH level, and RP-ILD were related factors for the prognosis of male anti-MDA5 antibodies [ HR (95% CI)=0.203(0.077, 0.534), P=0.001; HR (95% CI)=1.002(1.001, 1.004), P=0.003; HR (95% CI)=95.674 (10.872, 841.904), P<0.001]. Conclusion:The clinical manifestations of male anti-MDA5 antibody-positive patients are different from those of female. The incidence of ILD is low, but the proportion of PR-ILD is high. The course of disease, serum LDH level, and RP-ILD are prognostic factors of male anti-MDA5 antibody-positive patients.

OBJECTIVE To evaluate the effectiveness and safety of Panlongqi tablets in the treatment of fractures based on real-world research. METHODS From September 2021 to September 2023, fracture patients admitted to 33 medical institutions were collected retrospectively. Patients who received conventional treatment were divided into control group (n=3 750), and patients who received combination of Panlongqi tablets on the basis of conventional treatment were divided into observation group (n= 3 706). Self-reported indicators of patients were collected through telephone follow-up at 0, 4, 7 and 14 days after treatment. The improvement values of pain score, swelling score and health utility value, as well as effective rate and adverse drug reactions were compared between 2 groups. The propensity matching score (PSM) method was adopted to perform baseline matching on patient’s age, gender, fracture site, fracture severity, surgical type, type of hospital, and other indicators. Statistical analysis was performed on each therapeutic effect indicator. RESULTS After PSM, a total of 6 425 patients were included, of which 3 055 were in the observation group and 3 370 were in the control group. After 14 days of treatment, the observation group showed significant improvement in pain score (4.768 vs. 4.353), swelling fangshiyuan2008@126.com grading score (2.979 vs. 2.391), and life quality utility value (0.430 vs. 0.363), as well as effective rate (87.20% vs.75.99%) compared to the control group (P<0.05). The results of subgroup analyses conducted by gender, age, hospital type, and fracture site were consistent with the aforementioned results. In terms of safety, the observation group had no serious adverse reactions, with a total of 29 cases of mild adverse reactions such as dizziness, stomach pain, and allergies, with an incidence rate of 0.78%. CONCLUSIONS Panlongqi tablets combined with conventional treatment are significantly better than conventional treatment in improving pain, swelling, quality of life, and effective rate in patients with fractures, and have good safety.

Objective This study aimed to investigate the potential relationship between urinary metals copper (Cu), arsenic (As), strontium (Sr), barium (Ba), iron (Fe), lead (Pb) and manganese (Mn) and grip strength. Methods We used linear regression models, quantile g-computation and Bayesian kernel machine regression (BKMR) to assess the relationship between metals and grip strength.Results In the multimetal linear regression, Cu (β=-2.119), As (β=-1.318), Sr (β=-2.480), Ba (β=0.781), Fe (β= 1.130) and Mn (β=-0.404) were significantly correlated with grip strength (P < 0.05). The results of the quantile g-computation showed that the risk of occurrence of grip strength reduction was -1.007 (95% confidence interval:-1.362, -0.652; P < 0.001) when each quartile of the mixture of the seven metals was increased. Bayesian kernel function regression model analysis showed that mixtures of the seven metals had a negative overall effect on grip strength, with Cu, As and Sr being negatively associated with grip strength levels. In the total population, potential interactions were observed between As and Mn and between Cu and Mn (Pinteractions of 0.003 and 0.018, respectively).Conclusion In summary, this study suggests that combined exposure to metal mixtures is negatively associated with grip strength. Cu, Sr and As were negatively correlated with grip strength levels, and there were potential interactions between As and Mn and between Cu and Mn.

Objectives:To examine the proportion and trends of cervical adenocarcinoma in cervical cancer (ICC), mainly including cervical adenocarcinoma (CADC) and squamous cervical cancer (SCC) in China, and to analyze the distribution of human papilloma virus (HPV) in CADC and SCC.Methods:Published studies reporting HPVs distribution in various histological types or relative proportions of CADC in ICC in China were identified manually and searched systematically in Medline, Embase, Cochrane Library databases, CNKI and Wanfang since the databases were established until October 2022. Meta-analysis was performed using Stata 16.0 software. And we applied the random-effects models to estimate the combined effect values due to the high heterogeneity.Results:Twenty-three studies were eligible. The relative prevalence of CADC was 9.0% (95% CI, 7.7%-10.3%). According to the diagnosis time of ICC, the patients were divided into three time periods, which is 1979-2005, 2006-2011, 2012-2022 respectively. The prevalence of CADC by time was: 6.0% in 1979-2005, 8.1% in 2006-2011, and 9.5% in 2012-2022, respectively, with no statistically significant trend in proportions over time (χ 2=5.03, P=0.081). Meanwhile, the percentage of CADC also varies by regions, and the highest percentage of CADC was found in the eastern region (11.2%), followed by the western region (7.3%) and the central region (5.9%). The total prevalence of HPV infection in CADC was 72.3%, which was lower than 92.0% in SCC, and the difference was statistically significant (χ 2=300.89, P<0.01). To be specific, the top three HPV types prevalent in CADC were HPV18 (45.0%), HPV16 (22.0%), and HPV52 (7.3%), and those prevalent in the SCC were HPV16 (64.2%), HPV52 (5.6%), HPV18 (5.4%). The results of the Egger's test, and Begg's test showed that there was no publication bias in this study and sensitivity analysis showed that the results of this study were fairly stable. Conclusions:The proportion of CADC in China has increased in a limited way in the past decades, and there are regional differences in the proportion of CADC. The predominant type is HPV18 in CADC and HPV16 in SCC. To eliminate the limitations of the secondary literature, a multicenter study with consistent diagnostic levels and identical HPV genotyping tests is still needed in the future to better characterize the relative proportion of cervical adenocarcinoma and the trend of HPV changes, which will provide a basis for the improvement of HPV vaccine and screening policies.
