Objective To summarize the prescription characteristics and medication rules for the treatment of dia-betic kidney disease(DKD)from professor LIANG Xiaochun and to inherit professor LIANG Xiaochun's academic anamnesis.Methods Using the retrospective real world research(RWS)method and the electronic medical record of Peking Union Medical Union Hospital Information System(HIS),the clinical records of DKD outpatient treatment by professor LIANG Xiaochun's from 2020 to 2022 was collected to built a database with the support of Traditional Chinese Medicine inheritance computing platform(V3.5)software.Correlation analysis,cluster analysis and other methods were used to analyze the frequency of medication performance and the medication's four natures,five flavors,meridian tropism,and the combination of commonly used drugs in the treatment of DKD were re-viewed.Results A total of 205 cases covering 193 traditional Chinese medicines were collected.The most fre-quent use of drugs were Cuscutae Semen,Mori Cortex,Ligustri Lucidi Fructus,Achyranthes aspera Linn,Commelinae Herba,Smilacis Glabrae Rhizoma,Radix Et Rhizoma Rumei,Ramulus Euonymi Alati and Astmgali Radix.The four natures shared by them are cold and the five flavors are mostly sweetness.The meridian tropism belongs to the liver,spleen,and kidney.The analysis of drug association showed that the core drug combination was:Cuscutae Semen-Ligustri Lucidi Fructus,Cuscutae Semen-Achyranthes aspera Linn,Ligustri Lucidi Fructus-Achyranthes aspera Linn,Achyranthes aspera Linn-Smilacis Glabrae Rhizoma,Cuscutae Semen-Smilacis Glabrae Rhizoma etc.The four core prescriptions were obtained by cluster analysis:Cuscutae Semen-Ligustri Lucidi Fruc-tus-Mori Cortex-Achyranthes aspera Linn-Smilacis Glabrae Rhizoma-Radix Et Rhizoma Rumei,Cuscutae Semen-Commelinae Herba-Mori Cortex-Achyranthes aspera Linn-Ligustri Lucidi Fructus-Smilacis Glabrae Rhizoma,Cuscutae Semen-Ligustri Lucidi Fructus-Mori Cortex-Commelinae Herba-Achyranthes aspera Linn-Radix Et Rhizoma Rumei,Mori Cortex-Ligustri Lucidi Fructus-Cuscutae Semen-Astmgali Radix-Smilacis Glabrae Rhizoma-Commelinae Herba.Conclusions Professor LIANG Xiaochun treated DKD with the principle of tonifying the spleen and kid-ney,promoting blood circulation,and removing turbidity.The experience of medication embodies the academic anamnesis the combination of tonifying kidney and solidifying astringency,the combination of removing turbidity and detoxifying supplemented by activating blood and water circulation in human body.

Objective To reform the teaching content of acupuncture and moxibustion for undergraduate of Nursing College and to evaluate the effectiveness of the teaching reform,so to provide constructive information for optimizing the curriculum.Methods To revise the teaching content of Traditional Chinese Medicine(TCM)acu-puncture course based on the results of previous questionnaires,including reducing boring theoretical knowledge,increasing commonly used acupuncture techniques and clinical case analysis,organizing all undergraduates atten-ding the TCM teaching in the Nursing College of Peking Union Medical College to fill out the"Acupuncture Course Content Questionnaire"in 2023.The content covers four aspects:students'basic cognition of acupuncture and moxibustion before the course,students' learning feedback,students'learning effectiveness after the course and students' suggestions for further optimization of acupuncture and moxibustion course.Results Totally 149 students participated in the questionnaire survey and 73.15%of them were interested in the acupuncture course.There were 62.42%of the students thought that the most difficult part of the course was the"Acupuncture Points",and 71.81%of them complained the most constraining factor to the learning effectiveness was the diffi-culty of memorizing the meridians and acupoints.The most interesting part of the course was"Overview of Acu-puncture Treatment and Acupuncture Treatment of Common Diseases",which accounted for 44.3%of the students.Through the study,88.59%of the students were willing to recommend acupuncture treatment to pa-tients with indications.Students' suggestions for improvement of the acupuncture course was increase of classroom practice or learning by observation of operation videos.Conclusions The reformed acupuncture course highlights the practicability,improves the learning interest and subjective initiative,but the training of practice skill still needs to be strengthened.

Objective To screen the potential pharmacological targets of Ningzhi capsule,a lipid-lowering tradi-tional Chinese medicine,and explore its mechanism of effect.Methods The components and predicted targets of Ningzhi capsule′s constituent drugs were obtained from BATMAN-TCM database.Hyperlipidemia-related targets were obtained from DisGeNET and GeneCards databases.The Venny2.1.0 tool was used to map drug targets and disease targets to obtain common targets as potential pharmacological targets.Protein-protein interaction analysis(STRING),gene ontology and pathway enrichment analysis(DAVID)were performed for the common targets.Finally,Swiss dock was used for molecular docking verification.Results A total of 1 432 predicted targets of Ning-zhi capsule and 87 targets related to hyperlipidemia were found and 32 common targets were screened which covered 64 potential pharmacological ingredients of Ningzhi capsule.Potential pharmacological targets were most abundant for turmeric root-tuber,turmeric and cattail pollen,and potential pharmacological ingredients were most abundant for sickle senna seed,turmeric and turmeric root-tuber.Apolipoprotein E(APOE),nitric oxide synthase 3(NOS3)and peroxisome proliferator activated receptor alpha(PPARA)had the highest hyperlipidemia correlation scores and more protein interactions,which were potential core targets.The biological processes related to DNA transcription were significantly enriched.Cholesterol metabolism,cGMP-PKG and PPAR signaling pathways were involved with APOE,NOS3 and PPARA,respectively.Molecular docking showed good binding activity.Conclusions There are many potential pharmacological ingredients of Ningzhi capsule and the key components for lowering lipids include turmeric root-tuber,turmeric,cattail pollen and sickle senna seed.APOE,NOS3 and PPARA are believed to be the key targets for lowering lipids with potential mechanism related to cholesterol metabo-lism,cGMP-PKG and PPAR signaling pathways.

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.

Objective:To explore the trajectory of postpartum post-traumatic stress disorder (PP-PTSD) in women of advanced maternal age and its influencing factors.Methods:From September 2021 to March 2023, convenience sampling was used to select women of advanced maternal age in the Department of Gynecology and Obstetrics at Taizhou Hospital of Zhejiang Province as participants. Parturients were surveyed at one week, one month, six months, and 12 months after delivering using General Information Questionnaire, Post-traumatic Stress Disorder Check-list-civilian Version, Social Capital Scale, and 10-item Connor-Davidson Resilience Scale. The latent growth mixture model was used to analyze the trajectory of PP-PTSD.Results:A total of 467 questionnaires were distributed, and 456 valid questionnaires were collected, with a valid rate of 97.64%. There were four types of PP-PTSD trajectories in women of advanced maternal age, namely non PP-PTSD type (71.27%, 325/456), early onset-gradual recovery type (12.06%, 55/456), early onset-prolonged type (9.21%, 42/456), and late onset-risk type (7.46%, 34/456). Univariate analysis showed that delivery mode, pregnancy complications, social capital, and psychological resilience were potential categories of influencing factors for the trajectory of PP-PTSD in women of advanced maternal age ( P<0.05) . Conclusions:There is population heterogeneity in the trajectory of PP-PTSD among women of advanced maternal age. It is recommended that medical and nursing staff dynamically monitor the PP-PTSD of women of advanced maternal age, identify their trajectory types early, and develop precise intervention measures based on classification.
