OBJECTIVE To compare the emergency specialist clinical pharmacist training programs between China and the United States， providing valuable insight for the development of specialized clinical pharmacist training in emergency departments within China. METHODS By reviewing the official website of the American Society of Health-System Pharmacists （ASHP）， the websites of some training institutions offering PGY2 emergency medicine （EM） residency programs in the United States， the official website of China’s National Health Commission， and the website of the Pharmaceutical Affairs Committee of the Chinese Hospital Association， relevant materials and data on the training of emergency medicine clinical pharmacists were collected. Microsoft Excel and NVivo software were utilized to analyze the implementation status of these training programs. Literature searches were conducted via Chinese （CNKI） and English （PubMed） databases， followed by screening， categorization， and thematic analysis aligned with research objectives. RESULTS As of now， there are 115 accredited PGY2 EM residency programs in the United States， which provide 120 specialized pharmacist training positions. These programs are distributed across 35 states and are hosted by a variety of institutions， including hospitals， medical centers， and universities. The predominant training model follows a hospital+acute care framework. Eligibility requirements for PGY2 EM residency programs include possession of a doctor of pharmacy （Pharm.D.） degree， pharmacist licensure， and completion of a PGY1 residency. The training standards are structured into three tiers： competency areas， competency goals， and learning objectives. The curriculum typically includes core rotations， elective rotations， and longitudinal training components. Assessment is conducted through a combination of formative and summative evaluations， with results categorized into four proficiency levels. In China， there is only one training base currently for emergency clinical pharmacist specialty training with an annual enrollment of three trainees. Applicant eligibility primarily involves requirements regarding academic degree， professional background， years of experience， and professional title. The training content covers four domains： general competency， clinical theoretical knowledge and skills， pharmacological knowledge and application， and clinical medication practice skills. The training process centers on rotations within emergency departments. Assessment methods include theoretical examinations， daily performance evaluations， and final completion assessments. CONCLUSIONS PGY2 EM residency programs in the United States emphasize inclusivity and professionalism in their implementation. Program admission involves a rigorous selection process， and they offer attractive incentive structures for trainees. The training content focuses on competency-based approaches and pragmatic applicability， while assessment methods are closely aligned with defined competence objectives. In contrast， specialist clinical pharmacist training in emergency medicine in China is currently in the exploratory and nascent stages. Admission criteria tend to be less stringent， and incentives for trainees are often insufficient. The training content appears relatively stereotyped and superficial， with assessment methods still primarily reliant on quantifiable metrics. In expanding and popularizing China’s emergency specialist clinical pharmacist training programs， it is essential to draw on advanced experiences from developed countries like the United States， particularly in areas such as training base distribution， application requirements， training content， and assessment methods. Aligned with the realities of emergency clinical practice in China， efforts should focus on enhancing program accessibility and training efficacy.

OBJECTIVE: To investigate the mechanism by which dripping pills (STDP) improves coronary microcirculation disorder (CMD) and cardiac dysfunction in a porcine model of myocardial ischemia-reperfusion injury. METHODS: Fourteen minipigs were randomly selected for interventional balloon occlusion of the middle left anterior descending branch to induce CMD, and another 7 pigs received sham operation. The pig models of CMD were randomized equally into the model group and STDP-treated group. All the animals were fed with common feed for 8 weeks, and in STDP-treated group, the pigs were given STDP at the daily dose of 3 mg/kg (mixed with feed) for 8 weeks. Before and at the 8th week after the operation, the pigs underwent coronary angiography and echocardiography to determine the vessel lumen diameter and TIMI frame count (CTFC). The pathologies of the myocardium and the microvessels were examined with HE staining at the 8th week. Western blotting was used to detect the expression of silencing information regulator (Sirt1), peroxidase proliferator-activated receptor-γ coactivator-1α (PGC-1α), peroxisome proliferator-activated receptor α (PPARα), extracellular signal-regulated kinase1/2 (ERKI/2), Toll-like receptor 4 (TLR4), and uncoupling protein 2 (UCP2) in myocardial tissue. RESULTS: Before and at the 8th week after the operation, the diameter of the anterior descending vessel in the 3 groups did not differ significantly ( > 0.05). At the 8th week, the number of CTFC frames in the model group increased significantly compared with that in the sham-operated group, but was obviously lowered by treatment with STDP ( < 0.05). Myocardial ischemia-reperfusion injury significantly increased the interventricular septal thickness at end-diastole, left ventricular end-diastole dimension, end-diastole volume, interventricular septal thickness at end-systole and left ventricular mass at 8 weeks after the modeling ( < 0.05), but such changes were significantly alleviated by treatment with STDP (P < 0.05). STDP treatment markedly alleviated myocardial microvascular congestion, thrombosis and peripheral inflammatory cell infiltration induced by myocardial ischemia-reperfusion, but atrophy of the myocardial muscle fiber remained distinct. STDP obviously suppressed the down-regulation of Sirt1, PGC-1α, and PPARα and the up-regulation of ERK1/ 2, TLR4, and UCP2 in the myocardial tissues induced by myocardial ischemia-reperfusion injury. CONCLUSIONS STDP has anti-inflammatory effects and regulates energy metabolism in the myocardium through modulating Sirt1, PGC-1α, PPARα, ERKI/2, TLR4, and UCP2 to improve CMD and cardiac dysfunction after myocardial ischemia-reperfusion.

OBJECTIVETo investigate the possible effects of long-term exposure to dust containing thorium and thoron progeny on dust-exposed miners.

METHODSA negative, high voltage, exhaled thoron progeny measurement system was used to estimate the miners' thorium lung burden.

RESULTSThe highest thorium lung burden of 638 miners was 11.11 Bq. The incidence of stage 0(+) pneumoconiosis was higher among dust-exposed miners. Lung cancer mortality of the dust-exposed miners was significantly higher than that of controls (P < 0.005).

CONCLUSIONThere is a difference in cancer rates between those who have long-term exposure to dust containing thorium (in which carcinogenic ThO(2) and SiO(2) exist) and thoron progeny and those who have not.
