This study identified 8 members including NjBIN2 of the GSK3 family in Nardostachys jatamansi by bioinformatics analysis. Moreover, the phylogenetic tree revealed that the GKS3 family members of N. jatamansi had a close relationship with those of Arabidopsis. RT-qPCR results showed that NjBIN2 presented a tissue-specific expression pattern with the highest expression in roots, suggesting that NjBIN2 played a role in root growth and development. In addition, the application of epibrassinolide or the brassinosteroid(BR) synthesis inhibitor(brassinazole) altered the expression pattern of NjBIN2 and influenced the photomorphogenesis(cotyledon opening) and root development of N. jatamansi, which provided direct evidence about the functions of NjBIN2. In conclusion, this study highlights the roles of BIN2 in regulating the growth and development of N. jatamansi by analyzing the expression pattern and biological function of NjBIN2. It not only enriches the understanding about the regulatory mechanism of the growth and development of N. jatamansi but also provides a theoretical basis and potential gene targets for molecular breeding of N. jatamansi with improved quality in the future.

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.

OBJECTIVE: To evaluate the clinical efficacy and safety of Yangxue Qingnao Pills (YXQNP) combined with amlodipine in treating patients with grade 1 hypertension. METHODS: This is a multicenter, randomized, double-blind, and placebo-controlled study. Adult patients with grade 1 hypertension of blood deficiency and Gan (Liver)-yang hyperactivity syndrome were randomly divided into the treatment or the control groups at a 1:1 ratio. The treatment group received YXQNP and amlodipine besylate, while the control group received YXQNP's placebo and amlodipine besylate. The treatment duration lasted for 180 days. Outcomes assessed included changes in blood pressure, Chinese medicine (CM) syndrome scores, symptoms and target organ functions before and after treatment in both groups. Additionally, adverse events, such as nausea, vomiting, rash, itching, and diarrhea, were recorded in both groups. RESULTS: A total of 662 subjects were enrolled, of whom 608 (91.8%) completed the trial (306 in the treatment and 302 in the control groups). After 180 days of treatment, the standard deviations and coefficients of variation of systolic and diastolic blood pressure levels were lower in the treatment group compared with the control group. The improvement rates of dizziness, headache, insomnia, and waist soreness were significantly higher in the treatment group compared with the control group (P<0.05). After 30 days of treatment, the overall therapeutic effects on CM clinical syndromes were significantly increased in the treatment group as compared with the control group (P<0.05). After 180 days of treatment, brachial-ankle pulse wave velocity, ankle brachial index and albumin-to-creatinine ratio were improved in both groups, with no statistically significant differences (P>0.05). No serious treatment-related adverse events occurred during the study period. CONCLUSIONS Combination therapy of YXQNP with amlodipine significantly improved symptoms such as dizziness and headache, reduced blood pressure variability, and showed a trend toward lowering urinary microalbumin in hypertensive patients. These findings suggest that this regimen has good clinical efficacy and safety. (Registration No. ChiCTR1900022470).

OBJECTIVES: To investigate the mechanism by which transforming growth factor‑β (TGF‑β) regulates major histocompatibility complex class I (MHC-I) expression in hepatocellular carcinoma (HCC) cells and its role in immune evasion of HCC. METHODS: HCC cells treated with TGF‑β alone or in combination with SB-431542 (a TGF-β type I receptor inhibitor) were examined for changes in MHC-I expression using RT-qPCR and Western blotting. A RNA interference experiment was used to explore the role of miR-23a-3p/IRF1 signaling in TGF‑β‑mediated regulation of MHC-I. HCC cells with different treatments were co-cultured with human peripheral blood mononuclear cells (PBMCs), and the changes in HCC cell proliferation was assessed using CCK-8 and colony formation assays. T-cell cytotoxicity in the co-culture systems was assessed with lactate dehydrogenase (LDH) release and JC-1 mitochondrial membrane potential assays, and T-cell activation was evaluated by flow cytometric analysis of CD69 cells and ELISA for TNF-α secretion. RESULTS: TGF‑β treatment significantly suppressed MHC-I expression in HCC cells and reduced T-cell activation, leading to increased tumor cell proliferation and decreased HCC cell death in the co-culture systems. Mechanistically, TGF-β upregulated miR-23a-3p, which directly targeted IRF1 to inhibit MHC-I transcription. Overexpression of miR-23a-3p phenocopied TGF‑β‑induced suppression of IRF1 and MHC-I. CONCLUSIONS We reveal a novel immune escape mechanism of HCC, in which TGF‑β attenuates T cell-mediated antitumor immunity by suppressing MHC-I expression through the miR-23a-3p/IRF1 signaling axis.

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.

Objective To measure the distance between the lateral compression Ⅱ(LC-Ⅱ)screw guide needle and the surrounding important structures around the anterior inferior iliac spine in pelvic fractures and to locate the needle point,so as to provide anatomical reference for clinical nail placement.Methods Totally 40 adult gross specimens of embalming were implanted with LC-Ⅱ screw guide needle under the surveillance of C-arm machine,and the specimens were dissected.The shortest distance between the insertion point and the lateral femoral cutaneous nerve,femoral nerve,femoral artery,femoral vein,anterior superior iliac spine and inguinal ligament was measured.The triangle was constructed between the insertion point,anterior superior iliac spine and inguinal ligament,and the exact location of the entry point was calculated.Results The average distance between the insertion point of the male needle and the femoral vein was(50.67±7.29)mm＞the anterior superior iliac spine(43.83±7.58)mm＞the femoral artery(38.35±6.63)mm＞the femoral nerve(31.17±1.67)mm=the inguinal ligament(28.69±6.59)mm＞the lateral femoral cutaneous nerve(7.98±3.81)mm.The mean distance between the insertion point of the female needle and the anterior superior iliac spine was(45.28±7.07)mm=femoral vein(43.72±6.89)mm＞femoral artery(33.76±6.33)mm＞femoral nerve(25.66±6.46)mm=inguinal ligament(23.22±5.00)mm＞lateral femoral cutaneous nerve(8.97±4.76)mm.The projection distance of the entry point was 31.77 mm for men and 38.41 mm for women.The Angle b was 42.81°for men and 31.71° for women.Conclusion The lateral femoral cutaneous nerve is most vulnerable to injury when LC-Ⅱ screw is inserted,and the risk of injury has nothing to do with sex.The insertion point positioning method a and b made LC-Ⅱ screw placement quickly,safely and accurately,and reduced fluoroscopy time and frequency.

Objective:To evaluate the efficacy and safety of CD30 antibody-drug conjugates (ADC) brentuximab vedotin (BV) combined with chemotherapy in children with refractory or relapsed classic Hodgkin′s lymphoma (R/R cHL).Methods:Clinical data (including age, gender, B symptoms, clinical stage, previous treatment, etc.) of the 10 R/R cHL children diagnosed and treated at Beijing Children′s Hospital Affiliated to Capital Medical University from October 2021 to August 2023 were analyzed retrospectively. According to the different intensity of chemotherapy drugs, the dose of BV applied in the same course of treatment was 1.8 mg/kg for BV applied once every 3 weeks, and 1.2 mg/kg for BV applied once every 2 weeks. All 10 patients received at least 2 cycles of BV combined with chemotherapy and were evaluated every 2 cycles. The patients were followed up until May 31, 2024. The infusion reactions and adverse reactions after treatment were recorded.Results:In all 10 patients, there were 7 males and 3 females, the age ranged from 5.3-16.9 years, and there were 6 cases of refractory and 4 cases of relapsed. There were 6 cases of nodular sclerosis type, 2 cases of mixed cell type, 1 case of lymphocyte-rich type, and 1 case of lymphodepletion type. There were 5 cases of stage Ⅳ and 5 cases of stage Ⅲ. Previous treatment was mainly chemotherapy, 4 cases received radiotherapy and 1 case received programmed cell death protein 1 (PD-1) antibody therapy. The follow-up time ranged from 9 to 27 months. A total of 43 courses with 49 doses of BV alone or combined with chemotherapy were recorded, and the number of courses was 2 to 10 times. All 10 children responded to the treatment, and 9 achieved complete remission. BV infusion was successfully completed in all cases. A total of 28 cases of grade 3 or above adverse events were recorded, mainly myelosuppression, all of which were related to chemotherapy and did not affect sequential treatment.Conclusion:Brentuximab vedotin has demonstrated efficacy and a tolerable safety profile in the treatment of refractory and relapsed CD30-positive Hodgkin′s lymphoma in children.

Aim To explore the possible mechanism of "component-target-pathway" of Radix Hedysari against target organ damage caused by radiotherapy and chemotherapy, and to verify the " dose-effect" relationship of the main active components. Methods TCMSP, Uniprot, Swiss Target Prediction, GeneCards, Cytoscape, Omicshare and other platforms were used for network pharmacology analysis. Autodock, Pymol and Ligplot were used for molecular docking. The water extract of Radix Hedysari was used for animal experiment verification. The contents of eight main components were determined by HPLC. Results Four active components, eight key targets and four key pathways of Radix Hedysari were identified to resist the damage of target organs caused by radiotherapy and chemotherapy. Molecular docking showed that formononetin and quercetin had good binding activity with HSP90AA1, naringenin and MAPK3, and ursolic acid and TP53. Animal experiments showed that gastrointestinal factors MTL and VIP increased significantly, liver and kidney factors Cr, BUN, AST and ALT decreased significantly, inflammatory factor IL-10 increased significantly and TNF-a decreased significantly. The content of ononm was the highest (2 . 884 8 µg • g "

Objective To investigate the distribution of traditional Chinese medicine(TCM)syndrome elements in the patients with diarrhea-predominant irritable bowel syndrome(IBS-D)overlapping functional dyspepsia(FD),and to explore the characteristics of TCM syndromes in IBS-D overlapping FD.Methods Clinical investigation was performed for collecting the clinical data of patients with IBS-D,FD and IBS-D overlapping FD(overlapping group),50 cases for each disease.The TCM syndrome elements were analyzed by syndrome-element dialectical methods,and the characteristics of TCM syndromes and syndrome types were summarized by frequency analysis,association rule analysis and cluster analysis.Results(1)The results of frequency analysis showed that emotional disorder was the main inducing or aggravating factor in the overlapping group,followed by improper diet.The primary syndromes in the overlapping group were diarrhea,abdominal distension,epigastric fullness,abdominal pain and postprandial fullness;the tongue color was usually pale,pale red,dark or red,the tongue body was usually enlarged or tooth-marked,and the tongue coating was usually thin white or white;slippery pulse,wiry pulse,deep pulse and thin pulse were the common pulses.The diseases-location syndrome elements mainly involved spleen,stomach,small intestine and liver,and the disease-nature syndrome elements mainly involved qi stagnation,dampness,qi deficiency and yang deficiency.(2)The results of association rule analysis showed that the combination of abdominal distension and diarrhea had the highest support(accounting for 70.00％)associated with TCM syndromes,the combination of spleen and stomach had the highest support(accounting for 80.00％)associated with diseases-location syndrome elements,the two combinations of dampness and qi stagnation,qi deficiency and qi stagnation had the highest support(both accounting for 36.00％)associated with disease-nature syndrome elements.(3)The results of cluster analysis showed that TCM syndromes in the overlapping group were clustered into four categories of syndrome manifestations,namely spleen deficiency and dampness stagnation syndrome,spleen deficiency and qi stagnation syndrome,spleen yang deficiency syndrome and spleen qi deficiency syndrome;the combinations of syndromes and syndrome elements were clustered into five categories,namely manifestations of liver depression and spleen deficiency syndrome combined with intestinal dampness stagnation syndrome,manifestations of food stagnation in the stomach syndrome,manifestations of spleen deficiency and qi stagnation syndrome,manifestation of greasy coating,and manifestations of stomach qi failing to descend and rebellious stomach qi syndrome.Conclusion IBS-D overlapping FD usually affects the spleen,and is closely related to the disorders of the stomach,liver and small intestine.The main syndromes of IBS-D overlapping FD are spleen deficiency and dampness stagnation syndrome,and liver stagnation and spleen deficiency combined with intestinal dampness stagnation syndrome.Qi stagnation and dampness stagnation contribute to the key pathogenesis of IBS-D overlapping FD.IBS-D overlapping FD is characterized by the mixture of deficiency and excess,with the presence of pathological products such as phlegm-dampness,food accumulation and blood stasis in the later stage.
