Objective To explore the application and effectiveness of the apprenticeship education model in Chinese herbal medicine teaching at Western medical college.Methods By comparing classic lecture-based teaching with a combined approach integrating apprenticeship education,the study assesses the impact on student learning outcomes.Participants included students from the 2018 cohort of the eight-year clinical medicine program and the 2022 cohort of the"4+4"pilot program at Peking Union Medical College,who received classic teaching methods and apprenticeship case-based teaching methods,respectively.Upon course completion,students completed a 14-item multiple-choice questionnaire covering essential theory of Chinese medicine,as well as specific categories such as qi-regulating,blood-activating herbs,among others.Results The overall accuracy rate in the apprenticeship case-based teaching group was significantly higher than that in the classic teaching group(P＜0.01).Conclusions The apprenticeship education model of Traditional Chinese Medicine has a positive effect on teaching of Chinese herbal medicine at West-ern medical college and warrants further promotion and application.

Objective To explore the effectiveness of the"apprenticeship case-based teaching"method in the in-struction of traditional Chinese medicine(TCM)formulas for nursing students.Methods A quasi-experimental study was conducted with 135 undergraduate nursing students from the 2023 cohort at Peking Union Medical Col-lege.Participants were randomly assigned to an experimental group(receiving apprenticeship case-based teaching)or a control group(receiving conventional teaching).Teaching effectiveness was evaluated through classroom in-struction followed by a routine test.The test covered the indications and key diagnostic points of eight representative TCM formulas.Results The experimental group overruns the control group on most test items.Statistically signifi-cant differences(P＜0.05)were observed in questions related to Ma Huang Tang,Xiao Chai Hu Tang,Da Cheng Qi Tang,Liu Wei Di Huang Wan,and Ba Zheng San.Conclusions The apprenticeship case-based teaching meth-od significantly enhances students'learning gain about key diagnostic principles in TCM formulas and improves ca-pacity building of clinical reasoning.This method should be shared by schools of nursing in the teaching reformation of TCM curriculum.

The apprenticeship education of Traditional Chinese medicine(TCM)is an important pathway for the cultivation of talents in TCM education.The combination of institutional education and apprenticeship education is considered to be the most suitable educational model that aligns with the inherent characteristics of TCM education.The current status of TCM education in western medical institutions and the main challenges include the difficulty in transitioning between western and Chinese medical reasoning and limited clinical internship hours for TCM.The strengths and features of TCM apprenticeship education lie in cultural heritage,classical teachings,mentorship,practice orientation and personalized education.Therefore,integration of TCM apprenticeship education and clinical internships for western medical students represents a new educational model for medical undergraduates.

Ardisia Crenata Radix is a traditional Chinese medicinal plant that belongs to the Myrsinaceae family,and its main active components are coumarins,saponins,flavonoids,and volatile oil.Bergenin,ardisicrenoside A,ardisicrenoside B,ardisiacripin A,ardisiacripin B,and embelin were identified as active anticancer compounds in in-depth studies into the anti-tumor effects of Ardisia Crenata Radix.They show high therapeutic potential in oral cancer,nasopharyngeal carcinoma,liver cancer,colon cancer,bladder cancer,cervical cancer,and leukemia,mainly by inducing tumor cell apoptosis,increasing tumor cytotoxicity,inhibiting cell proliferation,inhibiting tumor cell metastasis and migration,and inducing cell regulatory enzyme cascade reactions.However,most preclinical experimental data on cinnabar root's anti-tumor mechanism have not been verified in high-quality,multi-sample,and repeated randomized controlled trials,and there are a lack of clinical research data on tumor prognosis,pharmacodynamics,and pharmacokinetics.Accurate research experiments and clinical trials should be designed to further explore the pharmacological effects of Ardisia Crenata Radix.

Objective To evaluate the teaching performance of the traditional Chinese medicine(TCM)course for the first three grades of the"4+4"reform pilot class in clinical medicine at Peking Union Medical College.Methods An anonymous survey was conducted using Questionnaire Star and the responses from TCM Teaching Questionnaire completed by students were statistically analyzed and summarized.Results Most students expressed interest in TCM and deemed it necessary to study TCM course.They believed that teachers well prepared for teach-ing performance and the teaching content was well-aligned with the textbooks,syllabus,and lecture slides.The teaching content was closely integrated with clinical practice,and students were satisfied with the teaching methods and approaches.Conclusions Teaching evaluations help teachers to summarize their teaching experiences and im-prove the teaching quality of the TCM course.

Objective To investigate the diagnostic efficacy of serum microRNA-375 (miR-375) and microRNA-760 (miR-760) combined liver enhancement computed tomography(CT) in hepatocellular carcinoma (HCC). Methods A total of 144 patients with HCC were included in cancer group, and another 144 patients with benign liver tumors in the same period were included in benign group. The expression levels of serum miR-375 and miR-760 were measured in both groups. Receiver operating characteristic (ROC) curves were plotted to analyze the diagnostic value of serum miR-375 and miR-760 expression levels combined with liver enhancement CT in HCC. The Kappa test was used to analyze the consistency of lonely detection of serum miR-375, miR-760 levels and liver enhancement CT, and their combined diagnosis for HCC with the gold standard pathological results. Results The expression levels of serum miR-375 and miR-760 in the cancer group were significantly lower than those in the benign group (P<0.05). The expression levels of serum miR-375 and miR-760 in patients with HCC were correlated with the number of tumor, tumor diameter, TNM stage, distant organ metastasis, degree of differentiation, portal vein tumor thrombus, and hepatitis B surface antigen (P<0.05). The ROC curve analysis showed that the area under the curve (AUC) of combined diagnosis of HCC using serum miR-375, miR-760, and liver enhancement CT was significantly greater than the AUC of individual diagnosis of the three methods (P<0.05), and there was a high consistency with pathological results (Kappa=0.826). Conclusion The expression levels of serum miR-375 and miR-760 in patients with HCC are lower than those in patients with benign liver tumors. The combined use of serum miR-375 and miR-760 levels and liver enhancement CT technology can significantly improve the diagnostic efficacy of HCC.

Objective To investigate the diagnostic value of computer tomography (CT) combined with serum secreted frizzled-related protein 4 (SFRP4) and soluble suppression of tumorigenicity 2 (sST2) for pancreatitis after biliary duct stent implantation in patients with malignant biliary obstruction (MBO). Methods A total of 243 MBO patients with biliary duct stent implantation were selected as research objects, and they were divided into pancreatitis group with 105 cases and no pancreatitis group with 138 cases according to condition of postoperative complicated pancreatitis. Enzyme-linked immunosorbent assay was used to detect serum levels of SFRP4 and sST2, and the receiver operating characteristic (ROC) curve and the four table method were used to analyze the diagnostic values of serum SFRP4 or sST2 alone and their combination with CT for postoperative complicated pancreatitis. Results The serum levels of SFRP4 and sST2 in the pancreatitis group were significantly higher than those in the no pancreatitis group (P < 0.05); the values of area under the curve (AUC) of serum SFRP4 and sST2 levels for diagnosis of postoperative complicated pancreatitis were 0.694 and 0.667, respectively. The sensitivity and specificity of CT for diagnosis of postoperative complicated pancreatitis were 76.19% and 60.87%, respectively; the sensitivity and accuracy of CT combined with serum SFRP4 and sST2 levels in diagnosing postoperative complicated pancreatitis were 98.10% and 76.54%, respectively; the sensitivity and accuracy of the combination of the three indexes for diagnosis were significantly higher than those of CT, SFRP4 or sST2 alone (P < 0.05). Conclusion MBO patients with pancreatitis after biliary duct stent implantation have higher serum levels of SFRP4 and sST2, and CT combined with serum levels of SFRP4 and sST2 has high diagnostic value for postoperative complicated pancreatitis.

The experimental class is a very important part of medical research graduate students in teaching practice. The lack of attention to experimental teaching, the unclear teaching purpose, and the disconnection between teaching content and practical application are the most important problems in current teaching practice. In this study, we propose to emphasize the experimental teaching objectives and experimental records to enhance students' initiative and standardize rigor; increase the training of advanced experimental equipment to improve students' hands-on ability; enrich teaching methods and means to improve teaching conditions; cultivate students' scientific thinking to enhance Student's experimental operating skills. The measures help comprehensively cultivate postgraduates' innovation and practical ability, and have great significance for medical research work.

Toxoplasma gondii, an obligate intracellular protozoan parasite of the phylum Apicomplexa, can infect all warm-blooded vertebrates, including humans, livestock, and marine mammals. The aim of this study was to investigate whether superoxide dismutase (SOD) of T. gondii can be used as a new marker for genetic study or a potential vaccine candidate. The partial genome region of the SOD gene was amplified and sequenced from 10 different T. gondii isolates from different parts of the world, and all the sequences were examined by PCR-RFLP, sequence analysis, and phylogenetic reconstruction. The results showed that partial SOD gene sequences ranged from 1,702 bp to 1,712 bp and A + T contents varied from 50.1% to 51.1% among all examined isolates. Sequence alignment analysis identified total 43 variable nucleotide positions, and these results showed that 97.5% sequence similarity of SOD gene among all examined isolates. Phylogenetic analysis revealed that these SOD sequences were not an effective molecular marker for differential identification of T. gondii strains. The research demonstrated existence of low sequence variation in the SOD gene among T. gondii strains of different genotypes from different hosts and geographical regions.
