Objective To explore the scheme for the deployment and withdrawal of the surgical module of the new-type tent hospital system.Methods A set of standardized scheme for deploying and withdrawing the surgical module of the new-type tent hosital system was proposed and implemented in terms of labor division,operation precedure,operation technique and precaution.The operating time,number of operational errors and number of equipment damages were recorded for each of the five deployment and withdrawal operations before and after the program was executed,and the team members'immediate heart rate,percentage of maximum heart rate(MHR)and rating of perceived exercise(RPE)at the end of the operation were recorded after the program was implemented.SPSS 26.0 software was used for statistical analysis.Results The standardized scheme had the deployment time shortened from(85.15±11.430)min to(58.23±8.513)min,withdrawal time decreased from(65.36±9.369)min to(48.92±7.129)min,with the differences being statistically significant(P＜0.05);the numbers of operatio-nal errors and equipment damages were both reduced when compared with those before the implementation of the schemce;the immediate heart rate of the team members at the end of the operation ranged from 43 to 157 beats/min,with an average value of 151.1 beats/min,the individual MHR percentages were from 75％to 87％,with an average value of 81.1％,and the RPE scores were from 14 to 17,with an average value of 15.3,which all could be categorized as moderate-operation intensity.Condusion The standardized deployment and withdrawal scheme for the surgical module meets the needs of actual combat and training assessment,and thus is worthy promoting in medical institutions equipped with the surgical module of the new-type tent hosital system.[Chinese Medical Equipment Journal,2025,46(2):74-79]

Depression is a highly heterogeneous psychiatric disorder with complex pathogenesis influenced by the interplay of biological,psychological,and social-environmental factors.Based on the 2021 edition of the Chinese Guidelines for the Prevention and Treatment of Depressive Disorders,which explicitly identify gender as a significant risk factor for depression onset,this paper systematically reviews the gender-differentiated pathogenesis and therapeutic advances in depression from both traditional Chinese medicine(TCM)and Western medical perspectives.In Western medicine,a large number of studies have demonstrated the sex-specific mechanism of estrogen/testosterone fluctuations and monoamine transmitter system regulation.While in TCM,although the constitution theory proposes that there are significant gender differences in congenital constitution and that qi depression and qi deficiency are associated with susceptibility to depression,current evidence primarily relies on cross-sectional surveys and lacks validation through high-quality RCTs.Compared with Western medicine,the direct research on gender-differentiated antidepressant effects in TCM remains relatively underdeveloped.In future study,it may be possible to deepen and improve the research on anti-depression in TCM from the biological markers of particular constitutions in the gender dimension.This paper advocates establishing a bio-psycho-social integrated intervention model,advancing mechanistic exploration through prospective cohort studies and multi-omics technologies,and promoting precision diagnosis and treatment systems based on gender differences,and to form a three-dimensional diagnosis and treatment and research system that covers biomarkers,social role assessment,and TCM constitution identification,in order to provide a new theoretical framework and a practical pathway for the precise medical treatment of depression.

This study aims to investigate the polarized microscopic mineral phase characteristics, inorganic element content, and potential health risks associated with the intake of raw and calcined fossil mineral Chinese medicinal material Draconis Os. Microscopy was employed to observe the mineralogical characteristics of Draconis Os and compare the microscopic features and phase composition of raw and calcined Draconis Os under monochromatic and orthogonal polarized light. Inductively coupled plasma mass spectrometry(ICP-MS) was employed to determine the content of 30 inorganic elements. Health risk assessment was conducted by calculating the single pollution index(P_i), average daily intake of elements for adults(ADI), target hazard quotient(THQ), non-carcinogenic assessment method-hazard quotient(HQ), and the carcinogenic risk of elements(CR). The results indicated that under monochromatic polarized light, the Draconis Os powder sections exhibited light gray-brown to gray-brown irregular fragments, some with undulating textures that were slightly curved. Under crossed polarized light, they appeared dark gray, grayish-white, and yellowish-white. Clear apatite was visible in the ground sections of Draconis Os under crossed polarized light. P_i results indicated that Draconis Os samples were free from contamination and were of good quality. According to the maximum allowable limits of heavy metals stipulated in ISO Traditional Chinese Medicine: Determination of heavy metals in herbal medicines used in Traditional Chinese Medicine, ADI, THQ, HQ, and CR were taken as assessment indicators. Only the THQ value for As(arsenic) in raw Draconis Os was greater than 1, while the THQ values for other heavy metal elements in the Draconis Os samples were all less than 1. The study demonstrates that the primary mineral phase of raw and calcined Draconis Os is apatite, with some samples co-existing with calcite, which can serve as one of the means for quality control of Draconis Os. The elemental analysis results from ICP-MS provide scientific evidence for the safety assessment of Draconis Os, indicating that Draconis Os is safe in clinical application.

Objective:To analyze the disease burden of respiratory syncytial virus (RSV)- associated lower respiratory tract infection (LRTI) in Chinese children under one year of age from 1990 to 2021.Methods:Using the Global Burden of Disease (GBD) 2021 database ( https://vizhub.healthdata.org/gbd-results/), we calculated deaths, mortality, age-standardized mortality rates (ASMR), disability- adjusted life years (DALYs), DALY rates, and age-standardized DALY rates (ASDR) to assess the disease burden of RSV-associated LRTI in Chinese children under one year of age. Joinpoint regression modeling was employed to analyze temporal trends in disease burden in China from 1990 to 2021, with stratification by time, age, and sex. Comparisons were made with global and high socio-demographic index (SDI) regions. Results:In 2021, there were 324 deaths (95% UI: 179-539) from RSV-LRTI in Chinese infants under one year of age, with a mortality rate of 2.82 per 100 000 (95% UI: 1.55-4.69), ASMR of 0.10 per 100 000 (95% UI: 0.06-0.16), DALYs of 29 131.28 years (95% UI: 16 050.27-48 398.30), DALY rate of 253.56 per 100 000 (95% UI: 139.70-421.26), and ASDR of 6.70 per 100 000 (95% UI: 3.72-11.12). All metrics were lower than global levels but significantly higher than high-SDI regions. From 1990 to 2021, substantial reductions were observed in deaths, mortality rates, DALYs, and DALY rates of RSV-LRTI among children under one year of age in China, globally, and in high-SDI regions. China achieved ASMR and ASDR reductions of－95.91% (95% CI:－97.75% to－92.96%) and－96.70% (95% CI:－98.19% to－94.33%), comparable to high-SDI regions but exceeding global averages. Joinpoint analysis showed average annual percentage changes (AAPC) in ASMR of－9.80% (95% CI:－10.45% to－9.14%) for China,－5.38% (95% CI:－5.83% to－4.91%) globally, and－7.13% (95% CI:－9.07% to－5.14%) for high-SDI regions (all P<0.001). The AAPC for ASDR were－10.41% (95% CI:－11.01% to－9.79%),－5.40% (95% CI:－5.82% to－4.97%), and－7.09% (95% CI:－9.70% to－4.41%) for China, the global average, and high-SDI regions, respectively, with the most pronounced decline occurring between 2019 and 2021 (ASMR decreased by 53.33%, 45.81%, and 61.31%, while ASDR declined by 52.50%, 44.54%, and 58.88% in China, globally, and in high-SDI regions, respectively). In 2021, both China and high-SDI regions exhibited declining mortality and DALY rates for RSV-LRTI with increasing age among children under one year, while neonates younger than 28 days consistently demonstrated the highest burden metrics. The rate of decline was comparable between China and high-SDI regions, with both exceeding the global average. Furthermore, from 1990 to 2021, male infants under one year of age in China, globally, and in high-SDI regions consistently showed higher overall trends in deaths, mortality rates, DALY, and DALY rates for RSV-LRTI compared to female infants. Conclusions:Although China's RSV-LRTI disease burden in infants under one year remains lower than global levels but higher than high-SDI regions, the country achieved reduction rates comparable to high-SDI regions, exceeding global averages. RSV-LRTI continue to pose significant health threats to neonates and male infants, necessitating age-specific and sex-specific prevention strategies.

Objective:To explore the prognosis of patients with acute aortic syndrome (AAS) in the real world and to examine the risk factors associated with poor outcomes in AAS.Methods:This is a single-center retrospective study. Patients diagnosed with AAS at Xinqiao Hospital from January 2021 to July 2023 were included. The primary endpoints were all-cause mortality and aorta-related mortality, while the secondary endpoints included stroke, myocardial infarction, secondary interventions, and readmission for any cause. Survival analysis was performed using Kaplan-Meier curves, and risk factors for primary endpoint events were analyzed using multivariate Cox regression.Results:A total of 254 AAS patients, aged (58.9±13.2) years were included in this study. There were 178 cases of aortic dissection, 69 cases of aortic intramural hematoma, and 7 cases of aortic penetrating ulcer. The median follow-up time was 545 days. Seventy-three all-cause deaths occurred among patients with AAS, including 61 aorta-related deaths; 3 strokes, 1 myocardial infarction, 9 secondary surgeries, and 35 readmissions for any cause were observed. Kaplan-Meier curve analysis demonstrated significant differences in all-cause mortality rates based on the Stanford classification, AAS disease classification, eGFR, and albumin levels (all P<0.05), and similar results were also observed in aorta-related death (all P<0.05). Multivariate Cox regression suggested that albumin<35 g/L ( HR=2.372, 95% CI 1.337-4.210, P=0.003), eGFR<90 ml·min -1·1.73 m -2 ( HR=2.457, 95% CI 1.261-4.786, P=0.008), and Stanford type A AAS ( HR=3.420, 95% CI 1.998-5.856, P<0.001) were independent risk factors for all-cause mortality in AAS patients; albumin<35 g/L( HR=2.432, 95% CI 1.295-4.570, P=0.006), eGFR<90 ml·min -1·1.73 m -2( HR=2.523,95% CI 1.243-5.122, P=0.010), and Stanford type A AAS ( HR=3.455,95% CI 1.819-6.564, P<0.001) were independent risk factors for aorta-related mortality in AAS patients. Conclusions:In the real world, the prognosis of patients with AAS remains pessimistic. Patients with type A AAS, renal dysfunction, hypoproteinemia may have a higher risk of poor prognosis.
