The inheritance, innovation, and development of traditional Chinese medicine(TCM) need to be based on Chinese medicinal materials. The TCM seed industry is the source of TCM production, which is related to the stable supply and quality safety of TCM. This paper summarizes the basic situation of the TCM seed industry and introduces relevant policies and regulations to TCM seeds in the seed industry and the TCM field. At present, the Management Measures of TCM Seeds and Seedlings has not yet promulgated, and TCM seeds are classified as non-major crops in the category of crops for management. This paper also describes the current situation of TCM seed and seedling system construction, which is in the development stage, from six aspects, including the construction of TCM seed industry technical support system; the establishment of TCM seed standard; the construction of germplasm resource preservation system; TCM seed testing, variety registration, and variety protection; production and management of TCM seeds; TCM seed supervision. According to the development status of the TCM seed industry, four problems are put forward, including imperfect systems and standards relevant to TCM seeds, insufficient supervision and law enforcement regarding TCM seeds, insufficient policy measures and capital investment to promote the development of the industry, and the industry's falling into a low-level cycle.Accordingly, four suggestions are provided, including improving laws, regulations, and policies, perfecting standards and norms,strengthening supervision and law enforcement, and promoting support system construction, in order to boost the high-quality development of the TCM seed industry.

This study aims to explore the effects of Buzhong Yiqi Decoction(BYD) on the cyclic guanosine monophosphate-adenosine monophosphate synthase(cGAS)-stimulator of interferon genes(STING) signaling pathway in the mouse model of autoimmune thyroiditis(AIT) and the mechanism of BYD in alleviating the immune injury. Forty-eight NOD.H-2~(h4) mice were assigned into normal, model, low-, medium-, and high-dose BYD, and selenium yeast tablets groups(n=8). Mice of 8 weeks old were treated with 0.05% sodium iodide solution for 8 weeks for the modeling of AIT and then administrated with corresponding drugs by gavage for 8 weeks before sampling. High performance liquid chromatography was employed to measure the astragaloside Ⅳ content in BYD. Hematoxylin-eosin staining was employed to observe the pathological changes in the mouse thyroid tissue. Enzyme-linked immunosorbent assay was employed to measure the serum levels of thyroid peroxidase antibody(TPO-Ab), thyroglobulin antibody(TgAb), and interferon-γ(IFN-γ). Flow cytometry was employed to detect the distribution of T cell subsets in the spleen. The immunohistochemical method was used to detect the expression of cGAS, STING, TANK-binding kinase 1(TBK1), and interferon regulatory factor 3(IRF3). Real-time PCR and Western blot were employed to determine the mRNA and protein levels, respectively, of markers related to the cGAS-STING signaling pathway in the thyroid tissue. The results showed that the content of astragaloside Ⅳ in BYD was(7.06±0.08) mg·mL~(-1). Compared with the normal group, the model group showed disrupted structures of thyroid follicular epithelial cells, massive infiltration of lymphocytes, and elevated levels of TgAb and TPO-Ab. Compared with the model group, the four treatment groups showed intact epithelial cells, reduced lymphocyte infiltration, and lowered levels of TgAb and TPO-Ab. Compared with the normal group, the model group showed increases in the proportions of Th1 and Th17 cells, a decrease in the proportion of Th2 cells, and an increase in the IFN-γ level. Compared with the model group, the four treatment groups presented decreased proportions of Th1 and Th17 cells and lowered levels of IFN-γ, and the medium-dose BYD group showed an increase in the proportion of Th2 cells. Compared with the normal group, the modeling up-regulated the mRNA levels of cGAS, STING, TBK1, and IRF3 and the protein levels of cGAS, p-STING, p-TBK1, and p-IRF3. Compared with the model group, the four treatment groups showed reduced levels of cGAS, STING, TBK1, and IRF3-positive products, down-regulated mRNA levels of cGAS, STING, and TBK1, and down-regulated protein levels of cGAS and p-STING. The high-dose BYD group showed down-regulations in the mRNA level of IRF3 and the protein levels of p-TBK1 and p-IRF3. The above results indicate that BYD can repair the imbalance of T cell subsets, alleviate immune injury, and reduce thyroid lymphocyte infiltration in AIT mice by inhibiting the cGAS-STING signaling pathway.

Since the promulgation of the first Drug Administration Law of the People's Republic of China 40 years ago in 1984, China has undergone four main stages in the traditional Chinese medicine(TCM) regulation: the initial establishment of TCM regulation rules(1984-1997), the formation of a modern TCM regulatory system(1998-2014), the reform of the review and approval system for new TCM drugs(2015-2018), and the construction of a scientific regulation system for TCM(2019-2024). Over the past five years, a series of milestone achievements of TCM regulation in China have been achieved in the six aspects, including its strategic objectives and the establishment of a science-based regulatory system, the reform of the review and approval system for new TCM drugs, the optimization and improvement of the TCM standard system and its formation mechanism, comprehensive enhancement of regulatory capabilities for TCM safety, international harmonization of TCM regulation and its role in promoting innovation. Looking ahead, centered on advancing TCMRS to establish a sound regulatory framework tailored to the unique characteristics of TCM, TCM regulation will evolve into new reform patterns, advancing and extending across eight critical fronts, including the legal framework and policy architecture, the review and approval system for new TCM drugs, the quality standard and management system of TCM, the comprehensive quality & safety regulation and traceability system, the research and transformation system for TCMRS, AI-driven innovations in TCM regulation, the coordination between high-quality industrial development and high-level regulation, and the leadership in international cooperation and regulatory harmonization. In this way, a unique path for the development of modern TCM regulation with Chinese characteristics will be pioneered.

OBJECTIVES: To identify risk factors for recurrent plastic bronchitis (PB) among children with Mycoplasma pneumoniae pneumonia (MPP). METHODS: The clinical data of children with MPP complicated by PB who underwent bronchoscopy at Gansu Province Maternity and Child Health Hospital between July 2023 and January 2025 were retrospectively analyzed. Patients were grouped into a single-episode PB group and a recurrent PB group according to the number of PB episodes. Multivariable logistic regression was used to identify risk factors for recurrent PB. Receiver operating characteristic (ROC) curve analysis was used to assess the diagnostic performance of individual and combined predictors. RESULTS: A total of 264 children were included; 188 (71.2%) had a single episode of PB and 76 (28.8%) had recurrent PB. Multivariable logistic regression analysis showed that decreased serum albumin, atelectasis, and fever persisting beyond 72 hours after the initial bronchoscopy were significantly associated with recurrent PB (all P<0.05). The combination of these predictors yielded a sensitivity of 82.9%, specificity of 61.7%, and an area under the ROC curve of 0.777 (95%CI: 0.714-0.839), outperforming any single predictor (P<0.05). CONCLUSIONS In children with MPP complicated by PB, decreased serum albumin, the presence of atelectasis, and fever persisting beyond 72 hours after the initial bronchoscopy are associated with an increased risk of PB recurrence. In such cases, early repeat or multiple bronchoscopic interventions should be considered.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

Ovarian aging is a reproductive endocrine disease caused by a variety of factors leading to a gradual decline in ovarian function until ovarian failure， which seriously affects women's physical and reproductive health and is a major factor leading to female infertility. Mitochondria， the energy metabolism centers of cells， are critical for ovarian functions. Their structural and functional abnormalities are key pathological factors leading to the declined ovarian function. Mitochondrial quality control is an important endogenous regulatory mechanism for the maintenance of mitochondrial homeostasis and the improvement of mitochondrial functions. Abundant studies have shown that the dysregulation of mitochondrial quality control， characterized by mitochondrial oxidative damage， abnormal mitochondrial biogenesis， abnormal mitochondrial dynamics， abnormal mitochondrial autophagy， and dysregulated calcium homeostasis， is closely associated with the occurrence of ovarian hypofunction. Traditional Chinese medicine （TCM） is a treasure of China's medicine， demonstrating remarkable efficacy in the clinical treatment of ovarian aging-related diseases. In recent years， research progress has been achieved in the TCM treatment of ovarian aging by regulating mitochondrial quality control disorders in a multi-target and multi-pathway manner. However， systematic research remains to be carried out regarding the research progress in this field. Therefore， this article reviews the research progress in the TCM treatment of ovarian aging based on mitochondrial quality control， with a view to providing a theoretical basis for studying the clinical efficacy of TCM in the treatment of ovarian aging and a new strategy for the in-depth research on the prevention and treatment of ovarian aging by TCM.

Objective To investigate the attributable risk(AR)of Acinetobacter baumannii(AB)infection in criti-cally ill patients.Methods A multicenter retrospective cohort study was conducted among adult patients in inten-sive care unit(ICU).Patients with AB isolated from sterile body fluid and confirmed with AB infection in each cen-ter were selected as the infected group.According to the matching criteria that patients should be from the same pe-riod,in the same ICU,as well as with similar APACHE Ⅱ score(±5 points)and primary diagnosis,patients who did not infect with AB were selected as the non-infected group in a 1:2 ratio.The AR was calculated.Results The in-hospital mortality of patients with AB infection in sterile body fluid was 33.3％,and that of non-infected group was 23.1％,with no statistically significant difference between the two groups(P=0.069).The AR was 10.2％(95％CI:-2.3％-22.8％).There is no statistically significant difference in mortality between non-infected pa-tients and infected patients from whose blood,cerebrospinal fluid and other specimen sources AB were isolated(P＞0.05).After infected with AB,critically ill patients with the major diagnosis of pulmonary infection had the high-est AR.There was no statistically significant difference in mortality between patients in the infected and non-infec-ted groups(P＞0.05),or between other diagnostic classifications.Conclusion The prognosis of AB infection in critically ill patients is highly overestimated,but active healthcare-associated infection control for AB in the ICU should still be carried out.

Objective To observe the differences in motor function and quality of life among mild-to-moderate Parkinson's disease(PD)patients with or without freezing of gait(FOG),and the correlation of FOG to motor function and quality of life. Methods From April,2021 to December,2022,132 mild-to-moderate PD patients aged 60 to 80 years were selected from Peking Union Medical College Hospital,and were divided into FOG group(n = 43)and non-FOG group(n = 89)according to the clinical features.They were assessed with Freezing of Gait Questionnaire(FOGQ),Berg Balance Scale(BBS),Timed"Up&Go"Test(TUGT),Five Times Sit to Stand Test(FTSST),isokinetic muscle strength,Unified Parkinson's Disease Rating Scale(UPDRS)and 39-item Parkinson's Disease Question-aire-39(PDQ-39). Results The BBS score was lower(Z =-2.354,P<0.05),and the TUGT,FTSST,UPDRS part 2 and part 3 scores,and the Parkinson's disease summary index(PDSI)were higher in FOG group than in non-FOG group(Z>3.074,t = 2.748,P<0.01).FOGQ score correlated with BBS score,UPDRS Part 2 and Part 3 scores,and PDSI(|r|>0.392,P<0.001). Conclusion FOG would impair motor function,activities of daily living and quality of life in mild-to-moderate PD pa-tients,and increase the risk of falls.

Berberine (BBR) is the main pharmacological active ingredient of Coptidis, which has hypoglycemic effect, but its clinical application is limited due to its poor oral bioavailability. Polyphenols, derived from cinnamon, are beneficial for type 2 diabetes mellitus (T2DM). The combination of both may have an additive effect. The aim of this study was to investigate the hypoglycemic effect and mechanism of combined medication in diabetic rats. The modeling rats were randomly divided into 5 groups (berberine group, cinnamon group, combined group, metformin group, diabetic control group) and normal control group. The animal experiments were approved by the Animal Ethics Committee (approval number: HMUIRB2022003). The subjects were given orally, and the control group was given equal volume solvent and body weight was measured weekly. Thirty days after administration, oral glucose tolerance test and insulin sensitivity test were performed, and fasting blood glucose (FBG), glycated serum protein (GSP), and serum insulin (INS) levels were detected; high-throughput sequencing technology was used to detect intestinal microbiota structure; real-time quantitative PCR (RT-qPCR) and Western blot were used to detect G protein-coupled receptor 5 (TGR5) and glucagon-like peptide-1 (GLP-1) expression levels. The results showed that, compared with the diabetic control group, the levels of FBG (P < 0.01) and GSP (P < 0.01) in the combined group were lower, and the insulin resistance was improved, which was better than that in the berberine group. Combined treatment increased the relative abundance of Bacteroides, Prevotella and Lactobacillus, reversed the decrease in Lactobacillus in the berberine alone induction group, and the combination of the two could promote the expression of TGR5 and GLP-1. In summary, the combined application of cinnamon and berberine can regulate glucose metabolism better than the application of berberine alone. Berberine combined with cinnamon can improve the function of pancreatic islet β cells in diabetes mellitus type 2 rats by changing the intestinal microbiota, increasing the expression of TGR5 and GLP-1 proteins, and thereby better regulating glucose metabolism.

Objective To investigate the role of dynamin-related protein 1(Drp-1)and peroxisome proliferator-activated receptor γ coactivator 1-α(PGC-1α)in the lung tissues of neonatal rats with meconium aspiration syndrome(MAS)and its mechanism.Methods Fifty 2-3-week-old SD neonatal rats were randomly divided into five groups(n=10):control group,model group and SN50 low,medium and high concentration groups.In control group,2 ml/kg of saline was injected into the trachea after tracheal exposure,and 2 ml/kg of meconium suspension was injected into the trachea of the rest of groups;after 24 h,control and model groups were left untreated,and 100 μl of each of SN50 concentrations of 10,30,and 60 μg/ml was injected into SN50 low,medium,and high concentration groups intraperitoneally;the rats of each group were killed after 6 h,and the chest X-rays,the gross views of the lungs,the lung wet/dry weight ratios(W/D),and the lungs of the rats in control group and model group were examined.After 6 h,the rats in each group were executed,and the pathological changes of lung tissue were observed by chest radiographs,lung gross view,lung wet/dry weight ratio(W/D)and HE staining;Western blotting was used to detect the changes of nuclear factor κB(NF-κB)(p65),p-NF-κB p65(p-p65),Drp-1,and PGC-1α proteins expression in neonatal rat lung tissues,and immuno-histochemistry was used to observe the expression of p65,Drp-1,and PGC-1α related proteins expression in neonatal rat lung tissues.Results Compared with control group,model group showed inflammatory infiltration in the chest radiograph and gross view,and the W/D and lung injury pathology scores were significantly higher(P＜0.05);compared with model group,the chest radiograph and gross view of inflammation were slightly reduced in SN50 low,medium and high concentration groups,and the W/D and lung injury pathology scores were significantly lower(P＜0.05).Western blotting showed that,compared with control group,the protein expression levels of p-p65 and Drp-1 in the lung tissues of neonatal rats were significantly higher in model group(P＜0.05),and the protein expression level of PGC-1α was significantly lower(P＜0.05);compared with model group,the protein expression levels of p-p65 and Drp-1 were significantly lower in SN50 low,medium,and high concentration groups(P＜0.05),and the difference in the protein expression level of PGC-1α in SN50 low concentration group was not statistically significant(P＞0.05),whereas the PGC-1α expression levels in SN50 medium and high concentration groups were significantly higher(P＜0.05);the difference in the total p65 protein expression levels in each group was not statistically significant(P＞0.05).Immunohistochemical assay results showed that,compared with control group,p65 and Drp-1 protein expression levels were significantly higher in model group(P＜0.05),and PGC-1α protein expression level was significantly lower(P＜0.05);compared with model group,p65 protein expression level was significantly lower in SN50 low concentration group(P＜0.05),and the difference in Drp-1 and PGC-1α protein expression levels were not statistically significant(P＞0.05),Drp-1 protein expression level was significantly lower(P＜0.05),and PGC-1α protein expression level was significantly higher(P＜0.05)in SN50 middle and high concentration groups.Conclusion Fecal inhalation can induce lung tissue inflammation in neonatal rats,and the mechanism may be related to enhanced oxidative stress,promotion of mitochondrial dysfunction,activation of the Drp-1/NF-κB signaling pathway,and inhibition of PGC-1α protein expression.
