Objectives:To analyze the disease burden and trends of ischemic stroke attributable to major metabolic risk factors in China from 1990 to 2021,and provide a basis for disease prevention and management.Methods:Based on the Global Burden of Disease(GBD)2021 data,we compared the age-standardized mortality rate(ASMR)and age-standardized disability-adjusted life year rate(ASDR)of ischemic stroke attributable to major metabolic risk factors(including overweight/obesity,hypertension,elevated low-density lipoprotein cholesterol,low bone density,hyperglycemia,and impaired renal function)in China and globally,and estimated their time trends through estimated annual percentage change(EAPC).We also analyzed the number of deaths,mortality rate,disability adjusted life year(DALY),and DALY rate of ischemic stroke attributable to major metabolic risk factors in China from 1990 to 2021,and compared the epidemiological differences among different gender and age groups.Results:From 1990 to 2021,the disease burden of ischemic stroke attributable to major metabolic risk factors in China showed a slight upward trend(1990 to 2005)and then gradually decreased,with a relatively small overall decline.,while the global disease burden showed a decreasing trend.In 2021,the ASMR and ASDR of ischemic stroke attributable to major metabolic risk factors in China were 48.11/100 000 and 898.35/100 000(EAPC[95%CI]were-0.24%[-1.13%to 0.66%]and-0.25%[-1.00%to 0.51%]),respectively,both higher than the global average levels(33.96/100 000 and 651.46/100 000,EAPC[95%CI]were-1.75%[-2.03%to 1.47%]and-1.49%[-1.74%to-1.23%],respectively).Compared with 1990,the actual mortality rate and DALY rate of ischemic stroke attributable to major metabolic risk factors in China increased by 139.60%and 110.53%respectively in 2021.There are gender differences in the disease burden of ischemic stroke attributable to major metabolic risk factors in China,with significantly higher death numbers,mortality rates,DALY,and DALY rates in males compared to females.At the age level,DALY and DALY rates were both higher in individuals aged 15-49,DALY increased but DALY rates decreased in individuals aged 50-69.DALY surged in individuals aged 70 and above,male DALY rates showed increasing trend and female DALY rates showed slightly decreasing trend.Conclusions:The disease burden of ischemic stroke in China is significantly affected by metabolic risk factors.Although prevention and control have achieved certain positive results,the overall disease burden in China is higher than that of the world,and precise intervention strategies need to be developed for different genders and ages in China.

Objective:To investigate the clinical efficacy of autologous adipose-derived stem cell gel (SVF-gel) grafting in the treatment of depressed acne scars.Methods:A retrospective analysis was conducted on data collected from 28 patients who underwent SVF-gel grafting treatment for depressed acne scars in the Department of Dermatology, Xijing Hospital, Air Force Medical University from October 2018 to May 2021. There were 17 males and 11 females, aged 17 - 38 (26 ± 4.86) years. As for clinical types, 8 patients were diagnosed with boxcar acne scars, 14 with rolling acne scars, and 6 with acne scars with characteristics of the two types. The clinical acne scar weighted scale (ECCA scale) was used to evaluate the appearance improvement after the treatment, and patients′ subjective satisfaction scores and incidence of adverse reactions were recorded.Results:After the SVF-gel grafting, the facial appearance of patients with depressed acne scars significantly improved, and the ECCA scores significantly decreased 6 months after surgery (before surgery: 52.5 ± 15.8 points; 6 months after surgery: 23.8 ± 10.2 points; t = 11.68, P < 0.001). The subjective satisfaction rate of patients was 82.14% (23/28), the incidence rate of adverse reactions was 17.86% (5/28), and 5 patients experienced mild inflammatory reactions after surgery, including 2 with subcutaneous nodules. The secondary grafting rate was 67.86% (19/28) . Conclusion:The SVF-gel grafting was markedly effective for the treatment of depressed acne scars, which is worthy of clinical promotion and application.

Objective To analyze the difference of diseases between the coal mine workers and the general population inpatients by the disease spectrum in Datong City. Methods A total of 282 639 hospitalized patients in Datong City in 2023 were included as the study subjects. Participants were divided into a general population group and a coal mine workers group based on health insurance types, with 247 897 and 34 742 cases, respectively. The disease spectrum of participants in both groups was coded and analyzed according to the International Statistical Classification of Diseases and Related Health Problems, 10th Revision (ICD-10). The standardized constituent ratios of disease categories were calculated and compared between the two groups. Results Patients aged 60-<70 years had the largest standardized proportion in both cohorts (29.02% in the general population group and 33.08% in coal mine workers group). Circulatory system diseases had the highest standardized proportion in both groups. Within the top six disease categories ranked by standardized composition ratio in the coal mine workers, three demonstrated a higher burden, including neoplasms (C00-D48), symptoms, signs and abnormal clinical/laboratory findings not elsewhere classified (R00-R99), and factors influencing health status/contact with health services (Z00-Z99), compared with the general population (11.82% vs 10.44%, 12.99% vs 8.03%, and 6.17% vs 2.04%, respectively). In both groups, male workers had higher standardized constituent ratios of circulatory, respiratory, and digestive system diseases than females (coal mine workers group, 19.53% vs 14.31%, 13.56% vs 9.10%, 10.61% vs 8.43%; general population group, 26.15% vs 22.42%, 15.45% vs 11.87%, 11.52% vs 10.41%). Conversely, the ratios for conditions classified under symptoms, signs and abnormal clinical/laboratory findings not elsewhere classified (R00-R99). and factors influencing health status/contact with health services (Z00-Z99) were higher in females than males (coal mine workers group, 13.31% vs 12.68%, 7.26% vs 5.13%; general population group, 8.91% vs 7.18%, 2.35% vs 1.74%). Mental and behavioral disorders (F00-F99) were most prevalent in the 22-<50-year age group in the general population (9.92%) and in the 50-<60-year age group in coal mine workers (8.58%). The standardized proportion of respiratory system diseases ranked first in≥80-year age workers in general population group and coal mine workers group (29.54% and 26.46%, respectively). Regarding specific malignancies, unspecified malignant neoplasm of the bronchus or lung was the most common cancer among males in both groups (3.44% and 3.62%). Among females, the standardized proportion of unspecified malignant neoplasm of breast was higher in coal mine workers group than in the general population group (2.60% vs 2.09%). Conclusion Neoplasms, abnormal symptoms, and mental health disorders should be prioritized in disease prevention strategies for coal mine workers. Greater attention should be paid to mental health screening in younger populations, and medical resource allocation should be optimized according to sex-specific high-incidence cancers.

Natural killer cells(NK)are important innate immune cells that do not require prior antigen exposure and can directly recognize and attack virus-infected cells and tumor cells.The activation and effector functions of NK cells are regulated by a balance of signals delivered through their surface activating receptors and inhibitory re-ceptors,which bind to ligands on target cells to achieve cytotoxicity via"induced self"and"missing self"recogni-tion models.The killing mechanisms of NK cells primarily include release of cytotoxic granules such as perforin and granzymes to induce target cell lysis,death receptor-mediated apoptosis,secretion of various cytokines,chemokines and growth factors to coordinate with other immune cells in killing tumor cells,thereby generating secondary im-mune responses and antibody-dependent cellular cytotoxicity(ADCC).

Objective To investigate the impact of smoking cessation on high-resolution compu-ted tomography(HRCT)phenotypes in smokers with chronic obstructive pulmonary disease(COPD)and its relationship with the frequency of acute exacerbations.Methods A retrospective study was conducted in 237 smokers with COPD who could cooperate with a 1-year follow-up.Among them,160 patients underwent a comprehensive 1-year smoking cessation intervention,and were divided into smoking cessation failure group(87 patients)and smoking cessation success group(73 patients)based on whether they successfully quited smoking.The remaining 77 smokers with COPD who did not receive smoking cessation intervention were designated as smoking group.HRCT phenotypes,total lung volume(TLV),total emphysema volume(TEV),emphysema index(EI)and the number of acute exacerbation at different time points were compared among the three groups.Pearson correlation analysis was used to explore the correlation between smoking cessation and the number of acute exac-erbations.Results There was no statistically significant difference in the proportion of A phenotype patients among the three groups before intervention and at 3 and 6 months of intervention(P＞0.05).At the 9th and 12th months of intervention,the proportion of patients with A phenotype in the smoking group was lower than that in the smoking cessation failure group and smoking cessation success group(P＜0.05).Before the intervention and at the 3rd,6th and 9th months of interven-tion,there were no statistically significant differences in the proportion of patients with E phenotype among the three groups(P＞0.05).Before intervention and at the 3rd and 6th months of interven-tion,there were no statistically significant differences in the proportion of patients with M phenotype among the three groups(P＞0.05).At the 9th and 12th months of intervention,the proportion of patients with M phenotype in the smoking group was higher than that in the smoking cessation failure group and smoking cessation success group(P＜0.05).Before intervention,there were no statisti-cally significant differences in TLV,TEV and EI among the three groups(P＞0.05).One year af-ter the intervention,TLV,TEV and El in the smoking cessation failure group and smoking cessation success group were lower than those in the smoking group(P＜0.05).At the 3rd,6th,9th and 12th months of intervention,the number of acute exacerbations in the the smoking cessation failure group and smoking cessation success group was less than that in the smoking group(P＜0.05).At the 9th and 12th months of intervention,the number of acute exacerbation in the smoking cessation success group was less than that in the smoking cessation failure group(P＜0.05).The results of Pearson correlation analysis showed that smoking cessation was negatively correlated with the number of acute exacerbation in smokers with COPD(P＜0.05),and this negative correlation gradually in-creased with the extension of smoking cessation duration.Conclusion Smoking cessation can im-prove HRCT phenotypes and effectively reduce the number of acute exacerbation in smokers with COPD.

Objective To mine and analyze adverse drug events(ADEs)of novel agents for multi-drug-resistant tuberculosis(MDR-TB)based on the FDA Adverse Event Reporting System(FAERS)database,to explore the signals of ADEs,and to provide reference for clinical use.Methods The FAERS database was searched and extracted from Q1 of 2015 to Q4 of 2023,and the ADE reports about bedaquiline,delamanid,and pretomanid were collected.Data mining and analysis were carried out on relevant reports of the drug using the reporting odds ratio(ROR),proportional reporting ratio(PRR),medicines and healthcare products regulatory agency(MHRA),and the Bayesian confidence progressive neural network(BCPNN).Results The number of ADE reports for the target drugs bedaquiline,delamanid,and pretomanid were 2 477,1 630,and 173,respectively.ADE of the target drugs involved multiple organ systems.Positive signals detected by the ROR,PRR,MHRA,and BCPNN methods were 246,246,215,204 for bedaquiline;251,251,224,200 for delamanid;and 25,25,24,22 for pretomanid.Clinically significant high-risk signals include prolonged QT interval on ECG,anemia,liver toxicity,peripheral neuropathy,etc.Conclusions The signal mining of ADEs based on the FAERS database indicates that close attention should be paid to risks such as prolonged QT interval on ECG,anemia,liver toxicity,and peripheral neuropathy during the clinical use of bedaquiline,delamanid,and pretomanid.In addition,monitoring of new potential ADE signals(such as acute heart failure,respiratory failure,acute kidney injury,etc.)should be strengthened,and timely intervention measures should be taken to ensure medication safety.
