Addressing the enduring challenge of evaluating traditional Chinese medicines (TCMs), the integrated evidence chain-based effectiveness evaluation of TCMs (Eff-iEC) has emerged. This paper explored its capacity through a demonstration study that evaluated the effectiveness evidence of six commonly used anti-hepatic fibrosis Chinese patent medicines (CPMs), including Biejiajian Pill (BP), Dahuang Zhechong Pill (DZP), Biejia Ruangan Compound (BRC), Fuzheng Huayu Capsule (FHC), Anluo Huaxian Pill (AHP), and Heluo Shugan Capsule (HSC), using both Eff-iEC and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The recognition of these CPMs within the TCM academic community was also assessed through their inclusion in relevant medical documents. Results showed that the evidence of BRC and FHC received higher assessments in both Eff-iEC and GRADE system, while the assessments for others varied. Analysis of community recognition revealed that Eff-iEC more accurately reflects the clinical value of these CPMs, exhibiting superior evaluative capabilities. By breaking through the conventional pattern of TCMs effectiveness evaluation, Eff-iEC offers a novel epistemology that better aligns with the clinical realities and reasoning of TCMs, providing a coherent methodology for clinical decision-making, new drug evaluations, and health policy formulation.

【Objective】 To explore the application of drones in blood emergency support during the 19th Asian Games Hangzhou in Shaoxing venue, so as to provide reference for future major events. 【Methods】 A retrospective analysis of drone delivery of emergency blood to two designated rescue hospitals in Shaoxing for the Asian Games was conducted. Ten emergency and 30 routine land blood delivery records from two designated hospitals in 2023 were randomly selected to compare with the blood delivery using drones. The blood temperature during the drone flight were monitored, the cold chain control during drone flight was evaluated, and the application of drone flight was reviewed. 【Results】 During the Hangzhou Asian Games, a total of 14 drones were used for blood delivery. The delivery time(min) by drone from the blood station to one of the designated hospitals was 11.83±0.09, and 20.80±3.29 by emergency land delivery and 23.23±3.54 by routine land delivery (P<0.05), meanwhile was 17.50±0.08, 24.50±3.27 and 26.57±3.23 respectively to the other hospital(P<0.05). Compared with land emergency blood delivery and routine blood delivery, blood delivery time by drone was much shorter, demonstrating better timeliness and stability. The temperature monitoring during the drone delivering showed that the suspended red blood cells and platelets were in a range of 3.8-6.8℃ and 21.8-22.8℃, with a temperature difference of 0.5-0.9 ℃ and 0.2-1.0℃ between takeoff and landing respectively, demonstrating that the blood cold chain was under control, and the delivery ran safely and smoothly. 【Conclusion】 During major events, the use of drones for emergency blood delivery ensures the quality of the blood, with good timeliness, feasibility and operability, and is worthy of promotion and application.

ObjectiveTo analyze the measures and effects of comprehensive noise control in an automobile engine manufacturing enterprise. Methods An automobile engine manufacturing enterprise with noise exposure work-sites was selected as the research subject. The noise hazard status of the enterprise was investigated. The noise hazard exceeded the national standard in work-sites was comprehensively treated. The treatment effect was analyzed. Results A total of 395 work-sites exposed to noise were detected. Among them, 16 work-sites exceeded the national noise standard, with the rate of 4.1%. The work-sites with noise exceeding the national standard were mainly in the machine workshop and the casting workshop, with normalization of equivalent continuous A-weighted sound pressure level to a nominal eight hours working day (L_EX,8h) ranging from 86.8 to 89.2 and 85.2 to 90.2 dB(A), respectively. In addition, the classification of occupational noise exposure of the mold protection group in the casting workshop was level Ⅱ, and classification of occupational noise exposure of other work-sites with excessive national standard was grade Ⅰ. After the enterprise implemented noise control measures such as process reform, equipment replacement, sound insulation, noise reduction, sound absorption, and vibration isolation, the L_EX,8h of nine positions were lower than those before rectification ［(86.7±1.1) vs (83.3±1.3) dB(A), P<0.01］. Conclusion The use of comprehensive control measures can achieve the purpose of reducing noise from the sources, and can be used for reference by relevant enterprises with noise hazards.

OBJECTIVE To study the antifungal activity of Huangqin decoction （HQD） against Trichophyton mentagrophytes and explore its mechanism. METHODS Minimal inhibitory concentration （MIC）， minimal fungicidal concentration （MFC）， mycelial length， spore germination rate， biomass and mycelium ultrastructure observation were performed to evaluate the antifungal activity of HQD against T. mentagrophytes. The effects of HQD on the cell wall of T. mentagrophytes were detected through sorbitol protection experiment. By measuring the content of ergosterol and the activities of squalene epoxide （SE） and lanosterol 14α-demethylase （CYP51）， the activity of HQD on the cell membrane of T. mentagrophytes was investigated. The effects of HQD on T. mentagrophytes mitochondria were investigated by determining the activities of malate dehydrogenase （MDH）， succinate dehydrogenase （SDH）， and ATPases （including sodium potassium ATPase， calcium magnesium ATPase， and total ATPase）. RESULTS HQD exhibited significant antifungal activity against T. mentagrophytes with MIC of 3.13 mg/mL and MFC of 25 mg/mL. After intervention with HQD， the mycelial length of T. mentagrophytes was significantly shortened （P＜0.05）； spore germination rate， biomass， the content of ergosterol in the cell membrane， the activities of SE and CYP51 in the cell membrane and MDH， SDH and ATPase in mitochondria were all decreased significantly （P＜0.05）； cell structure had been ；damaged to a certain extent， but the integrity of the cell wall had not been affected. CONCLUSIONS HQD shows significant antifungal activity against T. mentagrophytes， the mechanism of which may be associated with reducing the 0791- content of ergosterol in the cell membrane and the activities of SE， CYP51， and mitochondria-related enzymes.

Objective:To evaluate the practical value of the up-converting phosphor technology (UPT) in the field fast detection of plague, and to provide scientific basis for its promotion and application in the field work of plague monitoring.Methods:In September 2020, a total of 116 samples (including 4 samples for epidemic determination) were collected at the plague epidemic site in Menghai County, Yunnan Province, including 24 human blood and lymphatic fluid samples, 83 rat liver and muscle samples, and 9 rat blood samples. In March 2023, a total of 12 rat liver and muscle samples were collected from Lijiang City for on-site monitoring of plague outbreak (all of them were outbreak determination samples). All of the above samples were tested for Yersinia pestis antibody and antigen using the up-converting phosphor technology. At the same time, haemagglutination test, real-time fluorescence quantitative PCR and bacterial culture were conducted to compare the detection process and results of different experimental methods, the advantages and disadvantages of the up-converting phosphor technology for detecting Yersinia pestis were analyzed, and the feasibility of using this detection method in the field of plague epidemic monitoring was judged. Results:The plague epidemic samples site in Menghai County, Yunnan Province were tested by up-converting phosphor technology, and 19 samples were found to be positive for Yersinia pestis (1 antibody-positive and 18 antigen-positive). Among the samples determined, 4 samples with positive results of Yersinia pestis were detected by up-converting phosphor technology, and the results of their haemagglutination test, real-time fluorescence quantitative PCR and bacterial culture were all positive. All samples from Lijiang City were tested by up-converting luminescence technology, two samples were positive for Yersinia pestis(antigen-positive). The results of haemagglutination test and real-time fluorescence quantitative PCR were positive, and one sample was positive for bacterial culture. The time required for up-converting phosphor technology, haemagglutination test, real-time fluorescence quantitative PCR, and bacterial culture were 0.5, 4.0, 2.5 and 72.0 h, respectively. Conclusions:The results of Yersinia pestis detection by up-converting phosphor technology are basically consistent with the results of haemagglutination test, real-time fluorescence quantitative PCR and bacterial culture, but the time used is relatively short. When the number of samples is large, this method can be used preferentially in the field work of plague outbreak monitoring, which can quickly complete the preliminary judgement of plague outbreak, and save a lot of time and economic resources for the next step of plague prevention and control work.

Objective:To analyze the influencing factors for depression in primary school children aged 9-10 years in Jiangsu Province, and to construct a risk prediction model.Methods:A retrospective study.A total of 1 162 primary school children aged 9-10 years from 3 primary schools in 3 regions of Jiangsu Province were recruited.Their demographic data were collected, and they were surveyed by the Depression Anxiety Stress Scales-21 (DASS-21), the Strengths and Difficulties Questionnaire (SDQ), and the Family Environment Scale (FES). Children were divided into control group (1 059 cases) and depression group (103 cases) based on the depression scores obtained from the DASS-21 scale.Multivariate Logistic regression analysis was used to analyze the influencing factors for depression in primary school students aged 9-10 and construct a risk prediction model. Results:There were significant differences in the economic development region, physical activities, academic performance, student cadres, parents′ education level, frequency of parental quarrels, SDQ and FES dimension scores between control group and depression group (all P<0.05). Among them, economic development areas (Northern Jiangsu and Southern Jiangsu), student cadres, father′s education level (elementary school and below) and intimacy of the FES scale were protective factors for depression in elementary school children; while emotional symptoms, peer problems and the total difficulty score in the SDQ scale, and the conflict in the FES scale were the risk factors for depression in elementary school children.The prediction model was created based on the influencing factors: Logit ( P)=-1.390×economic development area (Northern Jiangsu) -1.508×economic development area (Southern Jiangsu) -1.248×student cadres -2.206×father′s education level (primary school and below) -1.145×father′s education level (junior high school)+ 3.316×emotional symptoms in the SDQ+ 0.979×peer problems in the SDQ+ 2.520×total difficulty score in the SDQ -1.697×cohesion in the FES + 0.760×conflict in the FES -0.678.The area under the curve of receiver operating characteristic was 0.931, with the sensitivity and specificity of 85.42% and 91.83%, respectively. Conclusions:The regional level of economic development, class or school cadres, father′s education level, peer problems, total difficulty score, cohesion and conflict in the family are influencing factors for depression among primary school children aged 9-10 years in Jiangsu Province.The created prediction model can effectively assess the depressive risk factors in this population, which is conductive to achieve the early recognition and intervention of depression in them.
