Parasitic diseases still remain the world's greatest health problems and cause huge economic burden in poor areas. The drugs currently used to treat protozoiases and helminthiases have certain defects, and it is urgent to develop more effective therapeutic drugs for these diseases. Berberine is one kind of important anti-inflammatory agents originally derived from Coptis rhizoma. The derivatives of berberine are obtained by modifying the structural site of berberine. In addition to its anti-inflammatory and anti-microbial activities, berberine and its derivatives also have significant anti-parasitic activity. In this paper, we summarized recent progress in the use of berberine and its derivatives against the infections of protozoa ( Leishmania spp ., Trypanosoma spp. , Toxoplasma gondii, Plasmodium falciparum, and Eimeria tenella) and helminths ( Schistosoma mansoni, Schistosoma. japonicum, Echinococcus granulosus, and Toxocara canis), which may providea useful reference for researchers in this field.

Objective:To investigate the relationship between enlarged perivascular space (EPVS) and retinal vessel abnormalities in transient ischemic attack (TIA) and mild stroke patients.Methods:TIA and mild cerebral infarction (National Institutes of Health Stroke Scale score≤3) patients were enrolled from March to August 2019 in Changzhou Second People′s Hospital. Magnetic resonance imaging and retinal fundus photography were performed in all patients. Retinal arteriovenous diameter was semi-automatically measured, and retinal arteriosclerosis grades, vascular curvature, hemorrhages, microangioma, hard exudation, soft exudation, arteriovenous nicking and venous beads were assessed. Patients were divided into two groups according to the existence of EPVS: EPVS group and non-EPVS group. The baseline data of the two groups were compared and further multivariate Logistic regression was carried out. After normal transformation of the number of EPVS, the correlation between the grades of EPVS and converted EPVS was analyzed. The relationship between the number of converted EPVS and the grades and retinal fundus vascular lesions was further analyzed.Results:A total of 123 patients were included, including 99 patients with cerebral infarction, 24 patients with TIA; 52 patients without EPVS and 71 patients with EPVS. The EPVS group was more than the non-EPVS group in age ((68.61±12.71) years and (63.37±13.53) years, t=-2.198, P=0.030), history of hypertension (52 (73.2%) and 25 (48.1%), χ 2=8.118, P=0.004), hemangioma (17 (23.9%) and 5 (9.6%), χ 2=4.196, P=0.041), arteriovenous nicking (50 (70.4%) and 8 (15.4%), χ 2=36.488, P<0.05) and arteriosclerosis grades (1 (1, 2) and 0 (0, 1), Z=-7.454, P<0.05), and less than the non-EPVS group in central retinal artery equivalent (CRAE; (106.31±15.02) mm and (113.89±11.86) mm, t=3.014, P=0.003) and arteriole-to-venule ratio (AVR; 0.54±0.07 and 0.59±0.05, t=4.553, P<0.05). Multivariate Logistic regression analysis showed arteriosclerosis grades ( OR=7.781, 95 %CI 2.876-21.055, P<0.05) and hypertension ( OR=3.203, 95 %CI 1.049-9.777, P=0.041) were related factors for EPVS. Adjusting for age, sex, hypertension and diabetes, the normally transformed EPVS was found positively correlated with arteriovenous nicking ( B=0.556, 95 %CI 0.203-0.910, P=0.003) and arteriosclerosis grade ( B=0.417, 95 %CI 0.259-0.576, P<0.05), and negatively correlated with AVR ( B=-4.213, 95 %CI-6.712--1.714, P=0.001). The grades of EPVS were positively correlated with arteriosclerosis ( r=0.764, P<0.05), and negatively correlated with CRAE ( r=-0.287, P<0.05) and AVR ( r=-0.422, P<0.05). Conclusions:Hypertension and retinal arteriosclerosis are related factors of EPVS in mild stroke and TIA patients. EPVS is correlated with retinal vessel abnormalities. The more serious of EPVS is, the more serious of retinal arteriosclerosis is, the higher ratio of arteriovenous nicking is, the smaller of CRAE and AVR are.

【Objective】 To explore the mediating effect of different organizational climate on volunteer service motivation and work engagement among volunteers during the COVID-19 epidemic. 【Methods】 The Volunteer Service Motivation Scale, Organizational Climate Scale, and Work Input Scale were used to investigate relevant contents among volunteers from Shaanxi, Hubei and Henan provinces who participated in prevention and control of the COVID-19 epidemic by convenient sampling method. Pearson correlation analysis was applied to explore the correlation among volunteer service motivation, organizational climate and work engagement. The Bootstrap method was used to analyze the mediating role of organizational climate between volunteer service motivation and work engagement. 【Results】 The scores of volunteer service motivation, organizational climate, and work engagement of the 834 volunteers were 72.45±13.66, 24.03±4.65, and 51.59±10.04, respectively. Volunteer service motivation was positively correlated with work engagement (r=0.556, P<0.001) and organizational climate (r=0.604, P<0.001). Organizational climate was positively correlated with work engagement (r=0.632, P<0.001). Organizational climate played a mediating role between volunteer service motivation and work engagement (effect value=0.278, accounting for 47.0% of the total effect). 【Conclusion】 Volunteer service motivation indirectly affects work engagement through organizational climate, indicating that volunteer team managers can improve their work engagement level by improving the organizational climate.

Objective To investigate the correlation between the residual cholesterol(RC)level and vertebrobasilar dilatation(VBD)in elderly patients with acute cerebral infarction(ACI).Methods A total of 325 elderly ACI patients admitted to Department of Neurology,Changzhou Second People's Hospital of Nanjing Medical University from January 2020 to July 2021 were recruited retrospectively.All of them underwent cranial MRI,CTA and biochemical test for plasma levels of TC,TG,LDL-C and HDL-C and other biochemical indicators.According to the imaging diagnostic criteria,they were divided into VBD group(52 cases)and non-VBD group(273 cases).Their clini-cal data were compared between the two groups,and the relationship between RC level and VBD was analyzed in the elderly ACI patients.Results Significant differences were observed in age,sex,hypertension,history of smoking and TC and RC levels between the VBD group and non-VBD group(P＜0.05,P＜0.01).Multivariate logistic regression analysis showed that after adjus-ting the potential confounding factors,age(OR=1.126,95％CI:1.065-1.191,P=0.000),male(OR=4.163,95％CI:11.173-10.120,P=0.002),and RC level(OR=1.270,95％CI:1.151-1.401,P=0.000)were independent risk factors for VBD in elderly ACI patients.Conclusion Age,male and RC level are independent risk factors for VBD in elderly ACI patients.High RC lev-el may increase the risk of VBD.

OBJECTIVE To investigate the basic situation of developing pharmacy outpatient departments in Chinese tertiary medical institutions and analyze the influencing factors. METHODS The research targeted the pharmacy outpatient department managers of hospitals and conducted a survey through Sojump in March 2023. Various independent variables were selected from the hospital’s own characteristics， the management of the pharmacy outpatient departments， and the construction of the pharmacist team for Logistic and linear regression analysis， with the aim of separately analyzing the factors influencing the establishment of pharmacy outpatient departments and the factors affecting the total number of patients served by these departments throughout the year 2022. RESULTS & CONCLUSIONS A total of 1 304 medical institutions of different levels nationwide participated in this survey， with 714 tertiary hospitals. Among the tertiary hospitals， 377 （52.80%） had established pharmacy outpatient departments， including 321 grade-A tertiary hospitals， 48 grade-B tertiary hospitals and 8 other tertiary hospitals. The 377 tertiary hospitals collectively operated 1 739 pharmacy outpatient departments， covering 19 specialized fields， with the highest proportion found in the cardiovascular field （including anticoagulation） at 16.45%. Tertiary hospitals in North China， Central China， East China and South China regions had more pharmacy outpatient departments. The establishment of pharmacy outpatient departments was found to be influenced by tertiary grade-B status （P＝0.010） and the annual outpatient volume of the hospital （P＝0.008）， although the impact was relatively small. The factors influencing the number of patients served by pharmacy outpatient departments were the annual outpatient volume of the hospital （P＝0.042） and the number of pharmacists engaged in clinical pharmacy work （P＝0.004）. The proportion of tertiary hospitals in China that have established pharmacy outpatient departments is insufficient. It is necessary to further accelerate the construction of pharmacy outpatient departments and appropriately expand the talent pool of hospital pharmacy teams based on the needs of pharmacy outpatient departments and patients， in order to meet the requirements of medical practice and patient care.

Gastrointestinal motility disorder is an important cause of digestive system diseases. Patients often suffer from nausea， vomiting， gastric retention， gastroparesis， constipation， and many other symptoms， and their quality of life is seriously reduced. Prokinetic agents are routinely used in clinical practice， but their long-term use is prone to problems such as reduced efficacy and increased adverse reactions. Since the incidence of gastrointestinal diseases has continued to rise globally in recent years， there is an urgent need for clinical development of safe and effective treatment strategies. Aurantii Fructus， a traditional Chinese medicine， has the effect of smoothing Qi and eliminating distention， and it has been used to treat gastrointestinal diseases for thousands of years. In modern clinical practice， it is mainly used for the treatment and auxiliary treatment of various gastrointestinal diseases such as functional dyspepsia， functional constipation， and irritable bowel syndrome. The efficacy is remarkable， and no adverse reactions have been reported at conventional doses. Therefore， it can greatly improve the symptoms of patients with gastrointestinal diseases and improve their quality of life. Modern research has revealed that there are many active components in Aurantii Fructus， among which flavonoids have the highest content and the most types. Flavonoids are the main active components in Aurantii Fructus to regulate gastrointestinal motility. Aurantii Fructus and its active components can affect gastrointestinal hormones， neural pathways， Cajal mesenchymal cells， and other multiple mechanisms. They can adjust gastrointestinal motility and correct gastrointestinal motility disorders， showing potential application value in the treatment of gastrointestinal motility disorders. However， a comprehensive analysis of Aurantii Fructus in this aspect is still lacking. This study summarized the pharmacological activities of active components of Aurantii Fructus extract and its flavonoids， volatile oils， alkaloids， and coumarin on the regulation of gastrointestinal motility and explored the latest research progress on its mechanism. Finally， the adverse reactions of Aurantii Fructus were summarized. It aims to provide a scientific basis for the research and clinical application of Aurantii Fructus and its active components in the regulation of gastrointestinal motility.

OBJECTIVE To investigate the development and current status of medication education in domestic medical institutions， aiming to provide reference and suggestions for better development of medication education. METHODS The online questionnaire survey was conducted in March 2023 to investigate the implementation of medication education in medical institutions at all levels nationwide； descriptive analysis and influencing factors analysis were conducted. RESULTS A total of 1 368 questionnaires were recycled， 1 304 of which were effective questionnaires， with the effective rate of 95.32%. The average rate of providing medication education was 73.62% in medical institutions nationwide， 76.05%， 67.68% and 73.76% respectively in Eastern， Central and Western regions， 87.11%， 60.57% and 46.32% respectively in tertiary， secondary and primary medical institutions. The commonest place and way of carrying out medication education were dispensing window and oral instructions， and both were more diverse in tertiary medical institutions， compared with second and primary medical institutions. The median annual service volume of medication education in medical institutions PUMCH-A- at all levels was 500 people； the higher the level of medical institutions， the larger the annual service volume of medication education （P＝0.023）. More than half of medical institutions didn’t have any form of compensation for medication education， which was mostly reflected in the workload of medical institutions with compensation. Grade of medical institutions， degree of information and automation were the major influencing factors of carrying out medication education. CONCLUSIONS The ratio of carrying out medication education is improved in the central region in China in recent years， compared with 2019； while that of primary institutions in all regions is at a low level and should be improved. The place of carrying out medication education should be set according to the characteristics of medical institutions， and medication education forms should be enriched as much as possible. The quantity and quality of medication education talents still need to be improved. Compensation for pharmaceutical care should be continually explored and implemented to prompt high-quality and sustainable development of medication education.
