Traditional Chinese medicine(TCM) resources are the essential material foundation for the development of TCM. The national survey of TCM resources serves as a periodic summary of these resources, ensuring the continuity, prosperity, and development of TCM in China. Since 1949, four national surveys of TCM resources have been conducted. The fourth survey incorporated an investigation into traditional knowledge related to TCM resources, including the traditional medicinal knowledge of Chinese ethnic minorities, with the goal of systematically exploring, preserving, and inheriting this knowledge. This manuscript provides an overview of the basic findings from the first three national surveys of TCM resources, while also clarifying the concepts, categories, forms, carriers, and acquisition pathways of traditional knowledge related to TCM resources. A preliminary summary of the findings from traditional knowledge investigations reported in current literature is also presented. Based on the fourth survey, this manuscript emphasizes the urgency of developing public medical knowledge through empirically-based investigations, the excavation, and compilation of traditional knowledge. It also outlines the potential for conducting "precise" investigations based on first-hand data obtained from the survey, as well as facilitating the discovery and evaluation of new medicines using traditional knowledge related to ethnic minority medicinal practices. This manuscript is expected to provide valuable insights for promoting the health and industrial development of ethnic minority populations in the post-"survey" phase.

Objective To summarize and evaluate the characteristics of current recurrent spontaneous abortion(RSA)animal models at home and abroad,and to provide reference and guidance for the standardized preparation of RSA models.Methods"Recurrent spontaneous abortion"and"animal model"were used as co-keywords in CNKI,Wanfang,VIP,PubMed and Web of Science databases to search the RSA animal experimental literature,covering the period up to January 20,2024,and a total of 1 411 articles were collected.The analysis focused on construction methods and essential elements of RSA animal models,the modeling process and result evaluation,as well as the application of these models in pharmacological and pharmacodynamic research.An Excel table was established for systematic analysis and discussion.Results A total of 138 experimental studies were obtained after screening.In constructing RSA animal models,immunological models were the most widely used in Western medicine(96.92％),with the Clark model being the main one(92.31％).In traditional Chinese medicine(TCM)models,70.00％were kidney deficiency-luteal inhibition-syndrome combination models,20.00％were kidney deficiency and blood stasis models,and 10.00％were deficiency-heat syndrome models.Most animals were selected at 6-8 weeks(33.86％)and 8 weeks(32.28％)of age.The majority of animals were paired for mating at 18:00 on the day of cage pairing.In 81.03％of literatures,vaginal plugs were checked once the following morning,with 8:00 being the most common time(17.02％).The most commonly used drug administration cycle was 14 days of continuous gavage after pregnancy.Among the tested drugs,Western drugs were mainly protein-based(29.17％),while TCM drugs were mainly TCM decoction(81.11％).The most frequently used methods for detecting indicators included visual observation of embryos(22.54％),western blot(15.96％),PCR(13.58％),ELISA(12.91％),HE staining(10.80％)and immunohistochemistry(9.39％).Conclusion The etiology of RSA is complex,and corresponding animal models should be established based on different etiologies.Clark model is commonly used in the construction of Western medicine model,while the kidney deficiency-luteal inhibition-syndrome combination model is predominant in TCM.RSA animal model is widely used in related research,but systematic evaluation needs to be strengthened.

Objective To explore the role and mechanism of cardiac resident macrophages in heart repair after myocardial infarction in mice.Methods Macrophage-specific Cre tool mice(CX3CR1CreER-YFP mice)with doubly transgenic mice(R26tdTomato/DTR mice)were hybridized to obtain cardiac resident macrophage-specific red fluorescent labels in mice.Sixty Cx3crlCreER-YFP:R26Td/DTR hybrid mice were randomly divided into 4 groups:Sham group,DT+Sham group,MI group,and DT+MI group,with 15 mice in each group.MI group and DT+MI group underwent myocardial infarction modeling by ligating the left anterior descending coronary artery.The DT+MI group mice were induced to deplete resident macrophages in the heart tissue using diphtheria toxin(DT)to establish a cardiac resident macrophage knockout model.On the 5th day after myocardial infarction modeling,heart tissue slices of mice were stained with H-E to observe inflammation infiltration and myocardial infarct size were calculated;on the 14th day of modeling,echocardiography was used to measure cardiac function-related parameters in mice,and mRNA expression levels of inflammatory cytokines were detected.Results Compared with the MI group,the DT+MI group mice showed a significant reduction in cardiac resident macrophages([53.75±4.62]vs[6.37±1.25],P＜0.05).On the 14th day after myocardial infarction modeling,compared with the Ml group,the DT+MI group mice had significantly increased left ventricular end-diastolic diameter([5.11±0.22]mm vs[5.92±0.26]mm,P＜0.05)and left ventricular end-systolic diameter([4.77±0.17]mm vs[5.38±0.16]mm,P＜0.05),while the ejection fraction significantly decreased([27.76±1.20]％vs[17.61±0.94]％,P＜0.05);in addition,the DT+MI group mice showed increased expression levels of inflammatory cytokines,increased inflammatory cell infiltration,and significantly larger myocardial infarct size.The protein expression levels of NF-KB/p-P65 in DT+MI group mice were significantly higher than those in the MI group([0.28±0.14]vs[1.09±0.12],P＜0.05).Conclusions Cardiac resident macrophages play an important role in heart tissue repair after myocardial infarction by reducing inflammation cell infiltration and myocardial infarct size.

Objective:To investigate the prevalence and mortality of dementia and assess the impact of geriatric syndromes (GS) on the risk for dementia and death in elderly population in Beijing.Methods:A cross-sectional survey was conducted in the elderly population aged ≥65 years and selected by a multi-stage sampling in Beijing during 2013-2015. Cognitive function was screened using the Chinese Revised Version of the Mini-Mental State Examination (MMSE). Then, neurological examination and psychiatric assessment were performed for those with the MMSE score lower than the cut-off value. The information about GS prevalence was also collected. The study also collected death records for all individuals from baseline until December 31, 2019. Based on the age and gender distribution from Beijing data of the 2010 Six th National Population Census, the dementia prevalence in the study population was directly standardized. Logistic regression analysis was used to evaluate the association of different forms of dementia with GS, and Cox proportional hazards regression model was used to estimate the hazard ratio ( HR) and 95% CI of death. Results:During 2013-2015, a total of 2 935 individuals completed dementia assessments, of which 167 were diagnosed with dementia. The standardized prevalence of dementia was 5.9% (95% CI: 5.0%-17.4%). The individuals with Alzheimer's disease (AD) and vascular dementia (VaD) accounted for 58.7% and 28.1% of total individuals with dementia, respectively. Aging, lower education level, urinary incontinence, and fall were risk factors for AD, while disability of activity of daily life dependence, hypertension, and stroke were found to be risk factors for VaD. After a median follow-up of 5.44 person-years, 399 deaths were recorded. The 5-year mortality risk was 2.87 (95% CI: 1.92-4.17) times and 4.93 (95% CI: 3.23-7.53) times higher for the elderly individuals with AD and VaD, respectively, compared to non-demented individuals. After adjusting for demographic, GS, and cardiovascular risk factors, the mortality risk in the elderly individuals with AD showed no significant difference compared with non-demented individuals ( HR=1.32, 95% CI: 0.89-1.97), while the mortality risk in those with VaD was 2.46 (95% CI: 1.49-4.05) times higher than that in non-demented individuals. Conclusions:The prevalence of dementia in Beijing increased significantly in the context of population aging, especially the prevalence of AD. The presence of GS increased the risks for AD and VaD, as well as the risk for death. Close attention needs to be paid to GS management in dementia prevention in elderly population.

Objective:To investigate the clinical and electrophysiological characteristics of patients with amyotrophic lateral sclerosis (ALS) with positive repetitive nerve stimulation (RNS) test results on the accessory nerve and negative needle electromyography (EMG) test results on the sternocleidomastoid with the goal to enrich the knowledge of disease progression in patients with ALS.Methods:The clinical data of 612 patients diagnosed with ALS at the Neurology Department of the First Medical Center, Chinese PLA General Hospital from June 2016 to August 2022 were collected. In total, 267 cases had undergone EMG tests on the sternocleidomastoid following a positive 3 Hz RNS test result on the accessory nerve, who were selected as the study subjects. The differences in clinical indicators were compared between RNS (+)/EMG (-) group and RNS (+)/EMG (+) group. A binomial distribution model with multiple variables was built to quantitatively analyze the major factors and their effects.Results:At the initial visit, 15.8% of patients with ALS were 3 Hz RNS (+) on the accessory nerve and EMG (-) on the ipsilateral sternocleidomastoid, accounting for 36.3% of RNS (+) patients. The decremental range of the 3 Hz RNS test delivered to the accessory nerve in these patients [-14% (-19%, -12%)] was lower than that in patients with RNS (+)/EMG (+) [-17% (-23%, -13%)] ( P<0.05), while the ratio of upper limb onset (64.9%) and non-definite diagnosis (28.9%) were higher [54.7% and 13.5% for patients with RNS (+)/EMG (+), P<0.05]. Furthermore, the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) score [40 (37, 42)], body mass index (BMI) [23.8 (22.0, 25.4) kg/m 2] and forced vital capacity (FVC) [92.8% (76.6%, 103.8%)] were higher in patients with RNS(+)/EMG(+) ( P<0.05). The multivariate model suggested that, in patients with RNS (+)/EMG (-), the ratio of upper limb onset to lower limb onset was 1.04, while that of upper limb onset to bulbar onset was 2.02, and that of lower limb onset to bulbar onset was 1.94. The ratio of non-definite ALS to definite ALS was 1.13. The ALSFRS-R score, BMI, and FVC had a protective contribution to the electrophysiological function of the motor neurons. The ratio of the effect size of the ALSFRS-R or BMI to that of FVC was 3.37 and 1.14, respectively. Conclusions:Patients with ALS that were 3 Hz RNS (+) on the accessory nerve and EMG (-) on the ipsilateral sternocleidomastoid had a smaller decremental range of the compound muscle action potential amplitude, and a higher proportion of upper limb onset and non-definite ALS. A higher ALSFRS-R score, BMI, and FVC have a protective effect to the electrophysiological function of motor neurons. The effect size of the ALSFRS-R score is the largest, followed by BMI and FVC.

Objective:To explore therapeutic efficacy and mechanism of puerarin(PUE)in treating of ulcerative colitis(UC).Methods:Network pharmacology and molecular docking technique were used to screen and analyze targets of PUE in regulating UC.C57BL/6 mice were given free access to 2.5%DSS aqueous solution for 7 days,and influence of PUE on changes in body weight and disease activity index(DAI)score were subsequently observed.Histopathological alterations of colon tissue were observed by HE staining,changes of goblet cell population in colon tissue were evaluated through Alcian blue staining;expressions of inflammatory factors in colon tissue were detected by qRT-PCR and ELISA.Effect of PUE on MODE-K cell viability and apoptosis were assessed by CCK-8 and flow cytometry.Results:A total of 38 common targets of PUE in modulating UC,such as AKT1,TNF,STAT3,CASP3,HIF1A and etc,mainly involving TNF,IL-17 and PI3K-Akt signaling pathway.In vivo experiments confirmed that PUE ameliorated degree of colon shortening,body weight and DAI scores and reduced inflammatory cell infiltration in mice.Besides,expressions of inflammatory factors in colon,such as TNF-α and IL-1β,were inhibited by PUE.Furthermore,in vitro experiments validated that PUE relieved DSS-induced apoptosis of epithelial cells.Conclusion:PUE alleviates occurrence and development of DSS-induced UC in mice.

This study established a school-supervisor-postgraduate "three-dimensional interaction" mode of academic norms and ethics education for medical postgraduates based on their training characteristics. The mode was evaluated and improved in practice. The results showed that after the implementation of the mode, graduate students significantly improved their awareness of how to standardize the implementation of experiments [(79.86% vs. 89.47%); P=0.021] and how to write formal experimental records [(84.72% vs. 92.76%); P=0.028]. In addition, there were significant increases in the pass rate of pre defense (85.42% vs. 94.08%; P=0.014) and blind review (84.03% vs. 93.42%; P=0.010). The "three-dimensional interaction" mode truly helps to achieve a win-win-win situation between postgraduate supervisors and the school, and is worth further practice and promotion.

Objective:To explore the effect of emotional imagery desensitization therapy on posttraumatic stress disorder among school- age children with fracture, to alleviate the adverse psychological state of the children.Methods:By a randomized controlled trials, a total of 78 school- age children with fracture at the Affiliated Hospital of Jining Medical University from July 2021 to July 2023 were divided into experimental group and control group according to the admission time, with 39 cases in each group. Both groups carried out routine care, the control group was given routine psychological intervention, the experimental group implemented emotional imagery desensitization therapy. Before and after 3 months of intervention, the effects was assessed by Post-Traumatic Stress Disorder Self-rating Scale (PTSD-SS) and Medical Coping Modes Questionnaire (MCMQ), respectively.Results:During the research process, there were 2 cases of dropout in the control group due to disconnection, and 4 cases in the experimental group due to disconnection and voluntary withdrawal. 37 children in the control group [20 males and 17 females, age (9.27 ± 1.62) years], and 35 children in the experimental group [21 males and 14 females, age (9.57 ± 1.63) years] completed the intervention. Before intervention, the difference of PTSD-SS and MCMQ scores between two groups was no statistically significant (all P>0.05). After intervention, the subjective assessment, re-experiencing, avoidance symptoms, hypervigilance, functional impairment factor scores and total PTSD-SS scores were (1.51 ± 1.06), (10.74 ± 3.30), (10.86 ± 2.93), (11.94 ± 3.18), (2.31 ± 1.30), (37.37 ± 6.37) in the experimental group, lower than in the control group (2.08 ± 0.80), (12.92 ± 3.63), (12.73 ± 2.99), (14.65 ± 4.23), (2.97 ± 0.87), (45.35 ± 5.86), the differences were statistically significant ( t=2.53-5.54, all P<0.05). After intervention, the confrontation subscale scores were (23.49 ± 2.48), higher than in the control group (21.89 ± 2.38), the avoidance, acceptance- resignation subscale were (10.31 ± 1.89) and (6.83 ± 1.98), lower than in the control group (11.57 ± 1.79) and (7.86 ± 2.12), the differences were statistically significant ( t=2.79, 2.89, 2.14, all P<0.05). Conclusions:Emotional imagery desensitization therapy can effectively alleviate post- traumatic stress disorder and promote positive coping mode in school-age children with fracture.
