Mediating role of mental fatigue between nature exposure and mental health of prison police / 环境与职业医学

Background The mental health status of prison officers is crucial to the efficiency, security, and stability of a prison, and it is essential to pay attention to the factors that influence their mental health. Objective To understand the mental health status of prison officers, and analyze how nature exposure affects their mental health problems and a potential mediating role of mental fatigue. Methods A cross-sectional survey was carried out from May to June 2022 among 1392 prison officers from eight prisons in a province, and a total of 1284 valid questionnaires were recovered. The Nature Exposure Scale, Mental Fatigue Scale, and Depression-Anxiety-Stress Scale were used to assess nature exposure, mental fatigue, and mental health indicators among prison officers, and to explore the effect of nature exposure on mental health problems and a potential mediating role of mental fatigue. Results The recruited prison officers showed high levels of depression, anxiety, and stress. The prevalence rates of depression, anxiety, and stress were 59.11% (759/1284), 60.67% (779/1284),and 43.93% (564/1284), respectively. The results of correlation analysis revealed that nature exposure was negatively related with mental fatigue and mental health indicators (depression, anxiety, and stress) (rs=−0.242, −0.308, −0.235, −0.254, P<0.01), while mental fatigue was positively correlated with mental health indicators (depression, anxiety, and stress) (rs=0.546, 0.533, 0.536, P<0.01). The PROCESS macro results showed that the level of nature exposure among prison officers negatively associated with depression, anxiety, and stress (β=−0.180, −0.104, −0.123), and mental fatigue played a mediating role, with indirect effects of −0.200, −0.192, and −0.199, respectively. Conclusion The levels of depression, anxiety, and stress of prison officers are higher than those of other occupations. Nature exposure negatively associates with depression, anxiety, and stress, that is, it may directly alleviate the mental health problems of prison officers; and it may also alleviate mental health problems by relieving mental fatigue.

A Novel Retrograde AAV Variant for Functional Manipulation of Cortical Projection Neurons in Mice and Monkeys / 神经科学通报·英文版

Retrograde adeno-associated viruses (AAVs) are capable of infecting the axons of projection neurons and serve as a powerful tool for the anatomical and functional characterization of neural networks. However, few retrograde AAV capsids have been shown to offer access to cortical projection neurons across different species and enable the manipulation of neural function in non-human primates (NHPs). Here, we report the development of a novel retrograde AAV capsid, AAV-DJ8R, which efficiently labeled cortical projection neurons after local administration into the striatum of mice and macaques. In addition, intrastriatally injected AAV-DJ8R mediated opsin expression in the mouse motor cortex and induced robust behavioral alterations. Moreover, AAV-DJ8R markedly increased motor cortical neuron firing upon optogenetic light stimulation after viral delivery into the macaque putamen. These data demonstrate the usefulness of AAV-DJ8R as an efficient retrograde tracer for cortical projection neurons in rodents and NHPs and indicate its suitability for use in conducting functional interrogations.

Oral anti-coagulants use in Chinese hospitalized patients with atrial fibrillation / 中华医学杂志(英文版)

BACKGROUND@#Oral anti-coagulants (OAC) are the intervention for the prevention of stroke, which consistently improve clinical outcomes and survival among patients with atrial fibrillation (AF). The main purpose of this study is to identify problems in OAC utilization among hospitalized patients with AF in China.@*METHODS@#Using data from the Improving Care for Cardiovascular Disease in China-Atrial Fibrillation (CCC-AF) registry, guideline-recommended OAC use in eligible patients was assessed.@*RESULTS@#A total of 52,530 patients with non-valvular AF were enrolled from February 2015 to December 2019, of whom 38,203 were at a high risk of stroke, 9717 were at a moderate risk, and 4610 were at a low risk. On admission, only 20.0% (6075/30,420) of patients with a diagnosed AF and a high risk of stroke were taking OAC. The use of pre-hospital OAC on admission was associated with a lower risk of new-onset ischemic stroke/transient ischemic attack among the diagnosed AF population (adjusted odds ratio: 0.54, 95% confidence interval: 0.43-0.68; P  <0.001). At discharge, the prescription rate of OAC was 45.2% (16,757/37,087) in eligible patients with high stroke risk and 60.7% (2778/4578) in eligible patients with low stroke risk. OAC utilization in patients with high stroke risk on admission or at discharge both increased largely over time (all P  <0.001). Multivariate analysis showed that OAC utilization at discharge was positively associated with in-hospital rhythm control strategies, including catheter ablation (adjusted odds ratio [OR] 11.63, 95% confidence interval [CI] 10.04-13.47; P <0.001), electronic cardioversion (adjusted OR 2.41, 95% CI 1.65-3.51; P <0.001), and anti-arrhythmic drug use (adjusted OR 1.45, 95% CI 1.38-1.53; P <0.001).@*CONCLUSIONS@#In hospitals participated in the CCC-AF project, >70% of AF patients were at a high risk of stroke. Although poor performance on guideline-recommended OAC use was found in this study, over time the CCC-AF project has made progress in stroke prevention in the Chinese AF population.Registration:ClinicalTrials.gov, NCT02309398.

Management of lung diseases under ultrasound monitoring: potential to make bronchopulmonary dysplasia in preterm infants as an avoidable disease / 中国当代儿科杂志

Bronchopulmonary dysplasia (BPD) is the most common chronic lung disease in preterm infants. Despite significant progress in the understanding of its etiology, mechanisms, prevention, and treatment, the prognosis remains poor. BPD not only has a high mortality rate but also causes persistent respiratory, neurological, and cardiovascular impairments in survivors. The author's team has successfully prevented the occurrence of BPD by managing neonatal lung diseases under lung ultrasound monitoring for nearly 7 years, opening up a new approach in BPD prevention. This article provides a brief overview of the approach, aiming to facilitate further research and provide more scientifically sound management strategies to prevent or minimize the occurrence of BPD.

Discussion on application of control level of radioactive contamination on personnel′s body surface in a nuclear and radiological emergency / 中华放射医学与防护杂志

There are differences and inconsistencies to some degree in the radioactive contamination control level of personnel′s body surface availiable in many national standards, thus puzzling the users. Therefore, it is proposed to compare the applicable scope, conditions and differences between relevant national standards, and combine with similar clinical nuclear medicine standards of radiological protection content to presevent recommendations on the contamination control level that should be correctly applied in an event of nuclear and radiological emergency. Based on the discussion of similar standards, the contaminated personnel with α of 0.04-10 Bq/cm 2 and β of 0.4-100 Bq/cm 2 are advised to be treated in the institutions with higher than secondary medical insititution. Both α econtamination control levels less than 0.04 Bq/cm 2 and β levels less than 0.4 Bq/cm 2 could be achivable, if fully decontaminated.

Hemodynamic study of patients with early allograft dysfunction after liver transplantation / 中华超声影像学杂志

Objective:To explore the characteristics of postoperative hemodynamic changes in patients with early allograft dysfunction (EAD), and to provide clinical imaging support for the early diagnosis of EAD.Methods:A total of 907 patients who underwent liver transplantation in Tianjin First Central Hospital from December 2012 to June 2021 were retrospectively selected, and they were divided into EAD group (361 cases) and non-EAD group (546 cases) according to EAD diagnostic criteria. The peak systolic velocity(PSV) of the hepatic artery, end-diastolic velocity(EDV) of the hepatic artery, resistance index(RI), S/D(PSV/EDV), diameter of the portal vein(PVD), velocity of the portal vein(PVV), diameter of the middle hepatic vein(MHVD), velocity of the middle hepatic vein(MHVV), the diameter of the right hepatic vein(RHVD), and the velocity of the right hepatic vein (RHVV) were collected from 1 to 7 days after operation (a total of 5 573 ultrasound examination results), and the differences in ultrasound hemodynamic parameters were compared between the two groups. The correlation of S/D<2, PSV<25 cm/s, PVV<15 cm/s, MHVV or RHVV<15 cm/s within 3 days after operation with the occurence of EAO were analyzed by multivariate Logistic regression analysis.Results:①The PSV and EDV of the hepatic artery in the EAD group and the non-EAD group showed a slow upward trend at 1-7 days after operation, while the hepatic artery RI and PVV showed a downward trend, the MHVV and RHVV did not fluctuate significantly. ②The hepatic artery in the EAD group showed low-resistance blood flow in the early postoperative period, and the EDV were significantly higher than that in the non-EAD group on 1 d, 2 d, 3 d and 5 d, RI was significantly lower than that of the non-EAD group (all P<0.05); At 4 d, 6 d and 7 d, there was no significant differences of EDV and RI between the two groups(all P>0.05). The PSV of the EAD group was higher than that of the non-EAD group on 3 d ( P<0.05). Among the parameters of portal vein blood flow, the PVV in the EAD group was significantly higher than that in the non-EAD group on 1 d ( P<0.05), and there was no significant difference of PVD between the two groups at day 1-7. Among the parameters of hepatic venous blood flow, the MHVV and RHVV in the EAD group were significantly lower than those in the non-EAD group (all P<0.05), there was no significant difference between the two groups of MHVD and RHVD at 1-7 days. ③The incidence of grafted hepatic artery S/D<2 within 3 days after operation in EAD group was higher than that in non-EAD group. Binary Logistic regression multivariate analysis showed that the occurrence of grafted hepatic artery S/D<2 within 3 days after operation was significantly correlated with the occurrence of EAD[Exp(B)=1.878, P<0.05]. Conclusions:Patients who develop EAD after liver transplantation show low-resistance blood flow in the hepatic artery during the perioperative period, and the occurrence of hepatic artery S/D<2 within 3 days after operation can early predict the occurrence of EAD.

Objective:To explore the potential categories of post-operative supportive care demand trajectory for patients with non-small cell lung cancer (NSCLC), analyze the influencing factors, and propose targeted interventions.Methods:This was a prospective observational study. A convenient sampling method was used to select 177 NSCLC patients who received surgical treatment in Shanghai Lung Hospital Affiliated to Tongji University from January 2021 to February 2022. The Supportive Care Demand Scale for cancer patients was used to investigate the level of patients′supportive care demand 1 day before operation, 3 days after operation, 1 day before discharge, 1 week after discharge, 1 month after discharge, and 3 months after discharge, and the potential growth model was used to identify the trajectory category and multi category Logistic regression analysis was used to explore the influencing factors.Results:Three supportive care demand trajectories were fitted out in this study, which were the continuous high demand group (46.33%), the slowly decreasing demand group (30.51%), and the low decreasing demand group (23.16%). With the potential category group 3, low demand reduction group as the reference category, Logistic regression analysis showed that high psychological distress, low social support, high disease stage, high comorbidities were more likely to enter the continuous high demand group ( OR = 0.826 to 18.526, all P<0.05), and high education level (college education and above and high school) were more likely to enter the slowly decreasing demand group ( OR = 6.076, 4.199, both P<0.05). Conclusions:The demand track of NSCLC patients for supportive care after surgery has population heterogeneity. Clinical medical staff should provide personalized social support and emotional support for patients with high disease stage, more complications and low education level in the early postoperative period.

Correlation between meconium-stained amniotic fluid and intrauterine infection / 中华实用儿科临床杂志

Fetal hypoxia has long been described as the main cause of meconium-stained amniotic fluid (MSAF). However, recent studies have reported the presence of a variety of pathogenic microorganisms in meconium and amniotic fluid, and even more bacterial species in MSAF.Clinical observations also revealed that MSAF was closely related to fetal-neonatal infection and perinatal infection of pregnant women.Shortly after birth, the fetuses with MSAF developed infectious symptoms or showed abnormalities in infection-related laboratory indicators.Therefore, intrauterine infection may be one major cause of MSAF.To further our understanding of the factors leading to MSAF will improve the clinical management and prognosis of infants.

Methods A cross-sectional study was performed from August to October 2019 and from June to September 2020 in seven provinces of China. Study participants were recruited from 21 manufacturing companies covering 11 manufacturing subdivisions using multistage stratified cluster sampling. General Burnout Scale, Core Occupational Stress Scale, and Patient Health Questionnaire-9 were used to evaluate job burnout, job stress, and depressive symptoms. Mann-Whitney U test and Kruskal-Wallis H test were used to compare data between two independent samples and multiple independent samples of measurement data; Pearson χ2 test was used to compare the rate of enumeration data; Spearman rank correlation analysis was used to evaluate correlation between selected variables; binary logistic regression was used for multivariate analysis; stepwise regression and bias-corrected Bootstrap method were used to test potential mediating effect. Results A total of 10973 valid questionnaires were collected. The M (P25, P75) scores of exhaustions, cynicism, professional efficacy, job burnout, job stress, and depressive symptoms were 1.6 (0.4, 3.0), 1.0 (0.2, 2.2), 4.8 (3.2, 5.7), 1.6 (0.8, 2.5), 45.0 (40.0, 50.0), and 7.0 (4.0, 11.0), respectively. The positive rates of job burnout, job stress, and depressive symptoms were 53.4% (5865/10973), 28.4% (3116/10973), and 29.4% (3231/10973), respectively. The influencing factors of job burnout were gender (versus male; OR for female=0.852), age (versus≤25 years old; ORs for 26-30, 31-40, 41-50, 51-60 years old=0.824, 0.819, 0.738, 0.677), education level (versus junior high school or below; ORs for senior high school/technical secondary school, junior college/vocational college, graduate school or above=1.119, 1.345, 1.331), income per month (versus＜3000 yuan; ORs for 3000-4999, 5000-6999, 7000-8999, 9000-10999, ≥11000 yuan=0.513, 0.470, 0.430, 0.375, 0.411), position (versus assembly line; OR for non-assembly line=0.814), average weekly working hours (versus ≤40 h; ORs for 61-70, ＞70 h=1.199, 1.519), and drinking (versus non-drinking; OR for drinking=1.261). Job burnout was positively correlated with job stress and depressive symptoms (r=0.556, 0.508, P<0.001). Job burnout played a partial mediating role between job stress and depressive symptoms, and its contribution value accounted for 63.2% of the total effect. Conclusion Manufacturing industry employees' job burnout problem is prominent in China, and there are many factors affecting job burnout. Job burnout may play a partial mediating role between job stress and depressive symptoms in the target group.

Five profiles and influencing factors of burnout-engagement continuum in working populations of China / 环境与职业医学

Background With the rise and deepening of positive psychology research, theoretical research on job burnout is also deepening worldwide, and some new theoretical models are proposed, such as the burnout-engagement continuum, but there is still a lack of empirical research and application in China. Objective To analyze the current situation and influencing factors of five profiles in the burnout-engagement continuum in working populations of China: job engagement, ineffective, overextended, disengaged, and burnout. Methods From August to October 2019 and June to September 2020, a total of 27344 subjects of key occupations in six typical industries, including teachers, firefighters, manufacturing workers, medical staff, flight attendants, and traffic police, were selected from 10 provinces (cities) in the eastern, middle, and western regions of China by multistage stratified cluster sampling method for cross-sectional investigation. Maslach Burnout Inventory-General Survey and Core Occupational Stress Scale were used to evaluate job burnout and occupational stress respectively. χ2 test was used to compare rates of count data. Binary logistic regression was used for multivariate analysis of the five profiles. Results Among the subjects, 24.4%, 61.9%, 31.9%, 12.7%, and 11.8% were the prevalence rates of job engagement, ineffective, overextended, disengaged, and burnout, respectively. Flight attendants (35.7%), firefighters (29.0%), traffic police (28.5%), and manufacturing workers (26.5%) had high prevalence rates of job engagement profile. Medical stuff (62.9%) and manufacturing workers (61.8%) had high prevalence rates of ineffective profile. Teachers (39.2%), traffic police (37.2%), and medical stuff (35.5%) had high prevalence rates of overextended profile. Traffic police (17.9%), medical staff (14.3%), and teachers (13.4%) had high prevalence rates of disengaged profile. Traffic police (16.9%), medical staff (13.4%), and teachers (13.3%) had high prevalence rates of burnout profile. The results of multivariate analysis showed that gender, age, education level, marital status, weekly working hours, length of service, income per month, shift work, smoking, drinking, industry, and occupational stress entered into the regression equations of job engagement, ineffective, overextended, disengaged, and burnout. The risks of overextended (OR=1.456-2.970), disengaged (OR=1.306-4.092), and burnout (OR=1.302-4.102) among the high rating groups of the four factors of occupational stress were higher than those among the low rating groups. Flight attendants (OR=0.296) and firefighters (OR=0.329) had lower risks of burnout than teachers, and flight attendants (OR=0.392) and firefighters (OR=0.466) had lower risks of disengaged than teachers. Conclusion Among the prevalence rates of the five profiles in the burnout-engagement continuum in the 6 typical occupational populations in China, ineffective profile is the highest, followed by overextended, and burnout is the lowest. Gender, age, education level, marital status, weekly working hours, length of service, income per month, shift work, smoking, drinking, industry, and occupational stress have different effects on the five profiles, but industry and occupational stress have greater impacts on job burnout.

2023 China Guidelines for Lipid Management / 老年心脏病学杂志（英文版）

Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of death among urban and rural residents in China, and elevated low-density lipoprotein cholesterol (LDL-C) is a risk factor for ASCVD. Considering the increasing burden of ASCVD, lipid management is of the utmost importance. In recent years, research on blood lipids has made breakthroughs around the world, hence a revision of China guidelines for lipid management is imperative, especially since the target lipid levels in the general population vary in respect to the risk of ASCVD. The level of LDL-C, which can be regarded as appropriate in a population without frisk factors, can be considered abnormal in people at high risk of developing ASCVD. As a result, the "Guidelines for the prevention and treatment of dyslipidemia" were adapted into the "China Guidelines for Lipid Management" (henceforth referred to as the new guidelines) by an Experts' committee after careful deliberation. The new guidelines still recommend LDL-C as the primary target for lipid control, with CVD risk stratification to determine its target value. These guidelines recommend that moderate intensity statin therapy in adjunct with a heart-healthy lifestyle, be used as an initial line of treatment, followed by cholesterol absorption inhibitors or/and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, as necessary. The new guidelines provide guidance for lipid management across various age groups, from children to the elderly. The aim of these guidelines is to comprehensively improve the management of lipids and promote the prevention and treatment of ASCVD by guiding clinical practice.

More than two courses of pre-transplant consolidation therapy benefits patients with acute myeloid leukemia in the first complete remission who underwent human leukocyte antigen-matched sibling allografts: a multicenter study / 中华医学杂志(英文版)

BACKGROUND@#Although the need for consolidation chemotherapy after successful induction therapy is well established in patients with acute myeloid leukemia (AML) in first complete remission (CR1), the value of consolidation chemotherapy before allogeneic hematopoietic stem cell transplantation remains controversial.@*METHODS@#We retrospectively compared the effect of the number of pre-transplant consolidation chemotherapies on outcomes of human leukocyte antigen-matched sibling stem cell transplantation (MSDT) for patients with AML in CR1 in multicenters across China. In our study, we analyzed data of 373 AML patients in CR1 from three centers across China.@*RESULTS@#With a median follow-up of 969 days, patients with ≥ 3 courses of consolidation chemotherapy had higher probabilities of leukemia-free survival (LFS) (85.6% vs . 67.0%, P < 0.001) and overall survival (89.2% vs . 78.5%, P  = 0.007), and better cumulative incidences of relapse (10.5% vs . 19.6%, P  = 0.020) and non-relapse mortality (4.2% vs . 14.9%, P  = 0.001) than those with ≤ 2 courses of consolidation chemotherapy. Pre-transplantation minimal residual disease-negative patients with AML in CR1 who received MSDT with ≥ 3 courses of consolidation chemotherapy had a higher probability of LFS (85.9% vs . 67.7%, P  = 0.003) and a lower cumulative incidence of relapse (9.6% vs . 23.3%, P  = 0.013) than those with ≤ 2 courses.@*CONCLUSION@#Our results indicate that patients with AML in CR1 who received MSDT might benefit from pre-transplant consolidation chemotherapy.

Impact of lncRNA FGD5-AS1 on the malignant biological behavior of bladder cancer cells by regulating miR-129-5p/CDK6 axis / 现代泌尿外科杂志

【Objective】 To investigate the impact of long non-coding RNA (lncRNA) FGD5-AS1 on the malignant biolo-goical behavior of bladder cancer (BC) cells by regulating micro RNA (miR)-129-5p/cyclin dependent kinase 6 (CDK6) axis. 【Methods】 Human BC cell line T24 was cultured from tumor tissue and paracancerous tissue of 105 patients with confirmed BC. The expressions of FGD5-AS1, miR-129-5p and CDK6 mRNA in tissue samples and T24 cells were detected with RT-qPCR. T24 cells were randomly divided into control group, si-NC group, si-FGD5-AS1 group, si-FGD5-AS1+inhibitor NC group and si-FGD5-AS1+miR-129-5p inhibitor group. The cell viability, migration, invasion andapoptosis were detected with CCK-8, Wound healing test, Transwell assay and flow cytometry, respectively. The expressions of Bax, Bcl-2, Caspase3 and CDK6 were detected with Western blot. The relationship between FGD5-AS1 and miR-129-5p, between miR-129-5p and CDK6 were verified with double luciferase reporter gene experiment. 【Results】 FGD5-AS1 and CDK6 mRNA were highly expressed in BC tissue, while miR-129-5p was lowly expressed (P<0.05). After FGD5-AS1 silencing, the expression of FGD5-AS1,A450 value, cell scratch healing rate, cell invasion number, and expressions of Bcl-2 and CDK6 were significantly lower, while the apoptosis rate and expressions of miR-129-5p, Bax and Caspase3 were significantly higher (P<0.05). Inhibition of miR-129-5p expression reversed the effects of FGD5-AS1 silencing on various indexes of BC cells (P<0.05). FGD5-AS1 negatively regulated the expression of miR-129-5p, and miR-129-5p negatively regulated the expression of CDK6. 【Conclusion】 Silencing FGD5-AS1 may inhibit the expression of CDK6 protein by up-regulating miR-129-5p, thus inhibiting the proliferation, migration and invasion of BC cells and promoting cell apoptosis.

Diagnosis and treatment recommendations of dialysis patients with SARS-CoV-2 infection for primary care clinicians / 西安交通大学学报(医学版)

End-stage renal disease (ESRD) patients undergoing outpatient hemodialysis (HD) and home peritoneal dialysis (PD) are high risk population of severe and critical types caused by SARS-CoV-2 infection. In order to improve the quality of diagnosis and treatment in dialysis patients with SARS-CoV-2 infection, we wrote this recommendation for primary care clinicians. During the epidemic period of SARS-CoV-2 infection, all patients should be instructed to strengthen self-management. Once the SARS-CoV-2 infection was found in dialysis patients, early stratified management should be carried out within 72 hours after the first positive nucleic acid or antigen test results, which includes early antiviral therapy, early recognition, and transferring severe patients from community or primary hospital to a referral hospital promptly. Guidance for dietary and sports rehabilitation after SARS-CoV-2 infection should also be started as soon as possible.

Matching strategy for patients with platelet transfusion refractoriness caused by compound antibodies against HLA and CD36 / 中国输血杂志

【Objective】 To search compatible and suitable platelets for platelet transfusion refractoriness (PTR) patient caused by compound antibodies against HLA and CD36. 【Methods】 ELISA method was used to detect the antibody against platelet antigens and the specificity of HLA-I antibody in PTR patients. The specificity of HLA-I antibody and corresponding epitopes of patients were analyzed using MATCH IT! and HLA Matchmaker software. The HLA genotype of both donor and patient was obtained by HLA-SSO method. Compatible or suitable donor platelets for PTR patients were searched through cross-reactive group (CREG) of HLA-I and HLA epitope-matched approach (Eplet). The matching degree was identified using monoclonal antibody-specific immobilization of platelet antigens (MAIPA) and the platelet suspension immunofluores-cence test (PIFT). Finally, the transfusion effect was evaluated according to the corrected count increment (CCI). 【Results】 Compound antibodies against both CD36 and HLA-I antigens were detected in two PTR patients, and their phenotype of CD36 was conformed to be type I deficient. Through LSA testing, high-frequency of HLA -I antibodies was found in these two patients, and the panel reactive antibody in patients 1 and 2 was 56% (54/96) and 53% (51/96), respectively. According to HLA-CREG and Eplet matching strategies, one donor of grade C-matching with patient 1 and one donor of grade D-matching with patient 2 were screened from the CD36 deficiency donor bank, respectively. And the selected donors avoided the antigen of HLA-I antibody epitope. These results of MAIPA and PIFT also confirmed that no immune response was detected between the patient and the donor. And a CCI of >4.5 within 24 hour of transfusion of compatible platelets was obtained in patient 2. 【Conclusion】 For PTR patients caused by HLA and CD36 compound antibodies, a combination strategy including serological cross-matching, HLA-CREG and Eplet approach should be used to select the CD36 deficient donor platelets which evaded the antigen corresponding to HLA-I antibodies and had the compatible HLA epitopes.

Interpretation of Teacher Training Syllabus for Clinical Pharmacist Training Program （2023 edition） / 中国药房

OBJECTIVE To interpret Teacher Training Syllabus for Clinical Pharmacist Training Program （2023 edition） （hereinafter referred as to the “new syllabus”）， and to provide reference and guidance for promoting the implementation of the new syllabus and realizing the quality-improving goal of the reform of the clinical pharmacist teacher training program initiated by China Hospital Association. METHODS From the perspective of the management and based on the position of the designer， the new syllabus was interpreted from four aspects： the background of its compilation and release， the process of its compilation and its characteristics， the key improvements of the program and the points for attention about its subsequent implementation. RESULTS & CONCLUSIONS The development and release of the new syllabus provide a “construction blueprint” for the reform of the clinical pharmacist teacher training program of the China Hospital Association. The whole process of compiling the new syllabus is characterized by four basic features： theory-led， goal-oriented， research-based， and synergistic. Compared with the previous syllabus， in addition to the adjustment of the text structure，the new syllabus presents more complete and clearer competence requirements for clinical teaching competence in terms of training objectives； in terms of training content， it further structures the group of task items， pays attention to the 育。E-mail：zhenjiancun@163.com sequential planning and time arrangement of items， and puts forward both quantitative and qualitative refinement requirements for each specific training task；in terms of training methods， it emphasizes the interaction of lecturing， demonstrating and guiding， and the progression of observation， operation and reflection， with the intention of guiding teacher trainees to “learn how to teach by teaching”. In the subsequent implementation of the new syllabus， it is necessary for the teacher training bases to attach great importance to the guarantee of training conditions and process quality management， and to organize the teacher training team to do a good job in the two training programs of “clinical pharmacist training” and “clinical pharmacist teacher training”. Based on further improving the connection between the two training programs， the teacher training team should continue to explore the scientific model of clinical pharmacist teacher training oriented by clinical teaching competence.
