Objective:
To analyze the monitoring results of key occupational hazard factors in workplaces across different industries in Aba Tibetan and Qiang Autonomous Prefecture (Aba Prefecture), Sichuan Province, so as to provide the basis for optimizing occupational disease prevention and control measures.
Methods:
Data of key occupational hazard factors in workplaces in Aba Prefecture from 2022 to 2024 were collected through the Workplace Occupational Hazard Monitoring System. Descriptive analyses were conducted on the over-standard rates of occupational hazard factors, completion rates of occupational health examinations, and participation rates in occupational health training.
Results:
From 2022 to 2024, 165 enterprise-times in Aba Prefecture were monitored, with 112 enterprise-times exceeding the standards, the over-standard rate of enterprises was 67.88%. A total of 1 005 worksite positions were monitored, with 302 exceeding the standards, the over-standard rate of worksite positions was 30.05%. The over-standard rates of enterprises and worksite positions showed upward trends from 2022 to 2024 (both P<0.05). The over-standard rates of enterprises in the ferrous metal mining and dressing industry and non-ferrous metal mining and dressing industry were both 100%. The top three over-standard rates of worksite positions were in the non-metallic mining and dressing industry, ferrous metal mining and dressing industry, and non-ferrous metal mining and dressing industry, at 62.50%, 56.00%, and 53.13%, respectively. Worksite positions exposed to silica dust, noise, and coal dust had relatively high over-standard rates, at 17.00%, 10.04%, and 7.27%, respectively. The actual numbers of physical examinations for personnel at worksite positions with dust, chemical factors, and physical factors were 9 398, 2 469, and 10 928 person-times, respectively, with completion rates of 95.78%, 81.03%, and 100.00%, respectively. The actual number of re-examinations were 428, 129, and 1 121 person-times, respectively, with re-examination rates of 64.26%, 27.27%, and 81.53%, respectively. Among the monitored enterprises, 102 enterprise-times participated in training for persons in charge, with a participation rate of 61.82%; 108 enterprise-times participated in training for occupational health management personnel, with a participation rate of 65.45%; and 10 489 person-times of workers exposed to hazards participated in occupational health training for workers, with a participation rate of 86.24%.
Conclusions
The over-standard rate of key occupational hazards factors in workplaces in Aba Prefecture was relatively high. The completion rate of occupational health examinations was good, but the re-examination rate was low. It is recommended to focus on strengthening the prevention and control of occupational hazard factors in the mining and dressing industry and promoting the effective implementation of occupational health examinations and occupational health training.

Breast cancer is globally the most common invasive cancer in women and remains one of the leading causes of cancer-related deaths. Surgery, radiotherapy, chemotherapy, immunotherapy, and endocrine therapy are currently the main treatments for this cancer type. However, some breast cancer patients are prone to drug resistance related to chemotherapy or immunotherapy, resulting in limited treatment efficacy. Consequently, traditional Chinese medicinal materials (TCMMs) as natural products have become an attractive source of novel drugs. In this review, we summarized the current knowledge on the active components of animal-derived TCMMs, including Ophiocordycepssinensis-derived cordycepin, the aqueous and ethanolic extracts of O.sinensis, norcantharidin (NCTD), Chansu, bee venom, deer antlers, Ostreagigas, and scorpion venom, with reference to marked anti-breast cancer effects due to regulating cell cycle arrest, proliferation, apoptosis, metastasis, and drug resistance. In future studies, the underlying mechanisms for the antitumor effects of these components need to be further investigated by utilizing multi-omics technologies. Furthermore, large-scale clinical trials are necessary to validate the efficacy of bioactive constituents alone or in combination with chemotherapeutic drugs for breast cancer treatment.

Objective To discuss the application value of work flow optimization based on hospital information system to shorten waiting time , improve nursing efficiency and ensure infusion safety in infusion center.Methods Process management combined with information technology was used to optimize the unreasonable work flow in infusion center .Self-designed questionnaire was used to compare the time between patients'arrival and leaving as well as the correct rate of nurses'transcription and typing of infusion cards before and after optimization .Results The average waiting time was ( 92.15 ±70.57 ) s before optimization and (64.34 ±37.59)s after, with statistically significant difference (Z=-6.704,P<0.01).The correct rate of transcription and typing of infusion cards improved from 96.5% to 99.3%, with statistically significant difference (χ2 =11.806 , P<0.01 ) .Conclusions The work flow optimization based on hospital information system can improve nurses'working efficiency, shorten patients'waiting time, reduce adverse incidence due to wrong transcription and typing of infusion cards and ensure the drug safety , so as to give patients effective and safe treatment and nursing in the infusion center .
