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 conduct preliminary evaluation of the reliability and safety of pancreatic duct-to-jejunum stent-bridging internal drainage as a supplementary approach to pancreaticojejunostomy in central pancreatectomy.Methods The clinical data of 28 patients who underwent robotic central pancreatectomy performed by our team between January 2021 and November 2024 were retrospectively collected,and and follow-up of postoperative endocrine and exocrine functions was performed.Based on the methods of digestive tract reconstruction adopted,the patients were divided into a conventional pancreaticojejunostomy group and a pancreatic duct-to-jejunum stent-bridging internal drainage group(PancreaticoJejunal-Stent bridge group).The operative time,digestive tract reconstruction time,and short-term complications were compared between the two groups.Results Among patients undergoing robotic central pancreatectomy,the digestive tract reconstruction time was shorter(t=5.168,P<0.001)in the PancreaticoJejunal-Stent bridge group([31.1±6.3]min)than that in the conventional pancreaticojejunostomy group([49.7±8.9]min)(t=5.168,P<0.001).The total operative time was(172.7±64.6)min in the PancreaticoJejunal-Stent bridge group and(200.1±52.7)min in the conventional pancreaticojejunostomy group,showing no statistically significant difference(t=1.215,P=0.235).In the PancreaticoJejunal-Stent bridge group,one patient developed a postoperative biochemical fistula,and 14 patients developed grade B pancreatic fistulas.Among the 14 patients with grade B pancreatic fistulas,1 case was complicated by fistula-related intra-abdominal infection,and 13 cases had drainage tube retention time of more than 21 days.In the conventional pancreaticojejunostomy group,2 patients developed postoperative biochemical fistulas,and 11 patients developed grade B pancreatic fistulas.Among the 11 patients with grade B pancreatic fistulas,1 case was complicated by fistula-related intra-abdominal infection,and 1 case was complicated by fistula-related intra-abdominal bleeding and infection.No postoperative gastroparesis,pancreatitis,or grade C pancreatic fistulas occurred in either group.There were no statistically significant differences between the two groups in overall postoperative complication rate(P=0.522),postoperative pancreatic fistula rate(P=0.583),intra-abdominal infection rate(P=0.583),or bleeding rate(P=0.464).Conclusion Pancreatic duct-to-jejunum stent-bridging internal drainage optimizes the anastomosis between the distal end of the pancreas and the jejunum during central pancreatectomy,shortens digestive tract reconstruction time,and reduces surgical complexity without increasing the risk of short-term severe postoperative complications.This approach is safe and feasible.

Objective:To explore the correlations of sleep quality and architecture with heart rate variability (HRV) in patients with stenoses of vertebrobasilar artery system and internal carotid artery system.Methods:A retrospective study was performed; 72 patients with stenosis or occlusion of the head and neck arteries (not resulting in cerebral infarction) admitted to Department of Neurology, Second Affiliated Hospital of Zhengzhou University from June 2023 to June 2024 were chosen, including 33 patients with moderate-to-severe stenosis or occlusion of the vertebrobasilar system (VB group) and 39 patients with moderate-to-severe stenosis or occlusion of the internal carotid artery system (ICA group). Pittsburgh sleep quality index (PSQI) and polysomnography (PSG) were used to evaluate the sleep quality and architecture, respectively; and 24-hour ambulatory electrocardiogram was used to assess the HRV. Differences in PSQI score, PSG and HRV parameters between the two groups were compared; partial correlation analysis was used to explore the correlations of HRV parameters with PSQI scores and PSG parameters; multivariate linear regression was used to analyze the independent influencing factors for HRV.Results:(1) Compared with the ICA group, the VB group exhibited significantly higher PSQI scores, spontaneous arousal index (SAI), ratio of time of stage 1 non-rapid eye movement sleep/total sleep time (T N1/T t), and apnea-hypopnea index (AHI), while significantly lower ratio of time of rapid eye movement sleep/total sleep time (T R/T t), spindle wave density in stage 2 non-rapid eye movement sleep (N2), lowest blood oxygen saturation, standard deviation of normal to normal intervals (SDNN) of all sinus beats, low-frequency power (LF), and high-frequency power (HF, P<0.05). (2) In both VB group and ICA group, SDNN was negatively correlated with PSQI score ( r=-0.461, P=0.020; r=-0.378, P=0.036). In the VB group, SDNN was negatively correlated with T N1/T t ( r=-0.467, P=0.019) and SAI ( r=-0.551, P=0.004), and positively correlated with ratio of time of stage 3 non-rapid eye movement sleep/total sleep time (T N3/T t, r=0.686, P<0.001) and spindle wave density in N2 ( r=0.518, P=0.008); LF and HF were negatively correlated with SAI ( r=-0.481, P=0.015; r=-0.564, P=0.003). In the ICA group, HF was negatively correlated with spindle wave density in N2 ( r=-0.369; P=0.041). (3) Multivariate linear regression results indicated that T N3/T t (β=0.348, P=0.018), SAI (β=-0.330, P=0.018), and spindle wave density in N2 (β=0.286, P=0.013) were independent influencing factors for Ln_SDNN in patients with moderate-to-severe stenosis or occlusion of the vertebrobasilar system. Conclusion:Patients with stenosis or occlusion of the vertebrobasilar system exhibit poorer subjective sleep quality, increased light sleep, heightened arousal, and reduced sleep stability compared with those with stenosis or occlusion of the internal carotid artery system, which may be caused by the imbalance of autonomic nerve function.

Objective To explore the feasibility,safety and efficacy of paclitaxel drug-coated balloon(DCB)in the treatment of atherosclerotic renal artery stenosis(ARAS).Methods A total of 28 patients with ARAS were selected.Balloon angioplasty was performed using a paclitaxel DCB at the site of renal artery stenosis(RAS)in these patients.Subsequently,a follow-up study was conducted to monitor various parameters of the patients,including vascular restenosis,blood pressure,the types of antihypertensive medications and renal function.The feasibility,efficacy and safety of balloon angioplasty using DCB in the treatment of ARAS were analyzed.Results Twenty-eight patients underwent 33 DCB balloon angioplasty.In one patient,there was no significant improve-ment in the degree of RAS,and thus further treatment with renal artery stenting was administered.The remaining patients all achieved both anatomical and hemodynamic success,with the degree of vascular stenosis at the lesion site decreasing from(79.74±5.13)％to(8.32±4.67)％,and the surgical success rate was 96.97％.The systolic/diastolic blood pressure of the patients was(179.16±30.65)mmHg/(108.26±20.93)mmHg(1 mmHg=0.133 kPa)at 24 hours postoperatively,(131.11±12.99)mmHg/(80.11±7.12)mmHg at 3 months postoperatively,(134.16±11.37)mmHg/(78.68±4.79)mmHg at 6 months postoperatively,and(133.37±12.71)mmHg/(80.11±4.84)mmHg at 12 months postoperatively.In comparison with the preoperative blood pressure of(184.63±27.64)mmHg/(109.11±22.26)mmHg,there was no significant decrease in blood pressure at 24 hours postoperatively,and the difference was not statistically significant.However,at 3,6,and 12 months postoperatively,the patients'blood pressure was signif-icantly lower than that before the operation,and all the differences were statistically significant.The glomerular filtration rate(GFR)was(36.19±18.32)mL/min at 24 hours postoperatively,(35.96±18.51)mL/min at 3 months postoperatively,(36.23±19.30)mL/min at 6 months postoperatively,and(35.59±18.26)mL//min at 12 months postoperatively,which all elevated compared with the preoperative GFR of(28.31±14.67)mL/min,and the differences were statistically significant(P＜0.05).At 3,6,and 12 months postoperatively,the vascular patency rate was 100％as indicated by multifunctional color Doppler ultrasound examination or renal artery computed tomography angiography(CTA).No relevant com-plications and postoperative adverse events,such as renal artery rupture or dissection,renal artery thrombosis and acute renal insuffi-ciency,occurred in all 28 patients.Conclusion The paclitaxel DCB is safe and reliable for the treatment of ARAS and has remarkable curative effects,and it can be used as an effective vascular treatment regimen for ARAS.

ObjectiveTo explore the relationship between the occupational noise exposure and arteriosclerosis in mechanical manufacturing workers. Methods A total of 453 employees of a machinery manufacturing enterprise were selected as the study subjects using the judgment sampling method. The noise exposure levels in their workplaces were measured, and their cumulative noise exposure (CNE) was assessed based on the type of job-noise exposure matrix and occupational hazard exposure history. Pure-tone audiometry was performed on the research subjects, and their brachial-ankle pulse wave velocity (baPWV) was measured. Results The CNE was (91±11) dB(A) per year and the median baPWV was 1 278.0 cm/s in the research subjects. The results of the generalized linear regression model analysis showed that for every one dB(A) per year increase in CNE, the baPWV of the general population increased by 0.20% ［95% confidence interval (CI) 0.10%-0.30%, P<0.01］, with an increase of 0.17% in males (95%CI 0.06%-0.28%, P<0.01) and 0.28% in females (95%CI 0.07%-0.49%, P<0.01). Using the hearing loss as an outcome indicator for high intensity noise exposure, the results showed that baPWV increased by 7.04% (95%CI 2.42%-11.87%, P<0.01) in individuals with bilateral hearing loss, and by 9.84% and 6.53% (95%CI 3.07%-17.07% and 2.13%-11.11%, all P<0.01) in individuals with elevated high-frequency hearing thresholds in both ears and in either ear, respectively. There was no significant association in elevated speech-frequency hearing thresholds and arteriosclerosis (P>0.05). Conclusion Occupational noise exposure may increase the risk of arteriosclerosis.

This article reports that a patient with bilateral ureterocutaneous stoma after radical cystectomy developed intermittent hematuria 2 years after surgery, and there were no abnormalities on bilateral renal artery and abdominal aortic angiography. After removal of the double J stent, a left common iliac artery ureteral fistula was seen on abdominal aortic angiography, and the patient immediately developed hemorrhagic shock. Abdominal aortic balloon occlusion and left common iliac artery stent grafting were performed in the emergency department. After the stent was deployed and the balloon deflated, no bleeding was observed, and the patient's heart rate and blood pressure stabilized. Follow-up angiography showed complete resolution of the fistula. This condition is rare and dangerous, but interventional treatment can quickly control bleeding, offering minimal surgical trauma and fast recovery.
