⁶⁰Co-γ ray irradiation has the unique advantages of high efficiency， strong penetration， operation at room temperature and no residue， which has been widely used in the sterilization of Chinese medicinal materials， decoction pieces， Chinese patent medicine. However， the irradiation effect may cause changes in the content of chemical components in Chinese materia medica or the emergence of new radiolysis products， leading to reduced efficacy and uncontrollable safety risks. This paper reviewed the relevant literature at home and abroad， summarized the effect of irradiation sterilization on various types of chemical compositions of Chinese medicinal materials and their preparations， and analyzed and explored the rule of change. The results showed that the content changes of various chemical components in Chinese materia medica after ⁶⁰Co-γ ray irradiation sterilization varied. The contents of most flavonoids， terpenoids， phenylpropanoids and quinones decreased after irradiation， and the degree of decrease increased with the elevated irradiation dose. The contents of lignans， alkaloids， isoflavones and some terpenoids did not change significantly before and after irradiation， while the content changes of triterpenoid saponins， dihydroflavonols， chalcones， sugars and glycosides after irradiation were not yet uniform. Therefore， it is recommended to pay attention to the compositional changes of irradiated Chinese medicines， strengthen the research on the standards of irradiated Chinese medicines， and standardize the irradiation and sterilization of Chinese medicines in order to promote the healthy and rational application of irradiated Chinese medicines.

OBJECTIVE To provide a reference for revising the safety content of traditional Chinese medicine（TCM） instructions. METHODS A systematic analysis was conducted on the relevant announcements on the revision of TCM instruction from 2013 to 2024， including the year of publication， drug name， drug formulation， announcement release time， and the average number of revisions made to three safety contents （contraindication， adverse drug reaction， and precaution）. According to the report data of national adverse drug reaction monitoring from 2013 to 2024， analyze the proportion of TCM in all adverse drug reactions， the composition ratio of adverse drug reaction of different dosage forms of drugs [TCM injection， oral TCM， other （topical） TCM]. RESULTS From 2013 to 2024， the National Medical Products Administration issued a total of 101 notices on the revision of TCM instruction， involving 241 types of TCM. Among them， there were 163 types of oral TCM， 25 types of TCM injection， and 53 types of other （topical） TCM. There were 3， 10 and 0 types of TCM injection， oral TCM， and other （topical） TCM with missing safety content， respectively. The main source of adverse drug reaction data for TCM injections was post- marketing monitoring data （accounting for 48.00%）； the main source of adverse drug reaction data for oral TCM was monitoring data （accounting for 71.17%）； 73.58% of other （topical） TCM did not mention the source of adverse drug reaction data. The report on national adverse drug reaction monitoring showed that the proportion of all adverse drug reactions of TCM had decreased from 17.3% in 2013 to 12.1% in 2024. Among them， the proportion of adverse drug reaction of TCM injection in the three dosage forms of TCM had decreased from 61.3% in 2015 to 24.6% in 2024， while the proportion of adverse drug reaction of oral TCM in the three dosage forms of TCM had increased from 34.7% in 2015 to 64.0% in 2024. CONCLUSIONS The risk management of TCM safety content has achieved results in China， but still faces three major challenges： strongdependence on passive monitoring， insufficient data traceability， and missing key content. It is urgent to improve safety content by dosage form， optimize data sources， and fully utilize real-world evidence to supplement safety content.

ObjectiveTo explore the clinical safety of Feilike Mixture （FLK） in the real world. MethodsThe safety of all children who received FLK from 29 institutions in 12 provinces between January 21，2021 and December 25，2021 was evaluated through prospective centralized surveillance and a nested case control study. ResultsA total of 3 035 juveniles were included. There were 29 research centers involved，which are distributed across 12 provinces，including one traditional Chinese medicine （TCM） hospital and 28 general hospitals. The average age among the juveniles was （4.77±3.56） years old，and the average weight was （21.81±12.97） kg. Among them，119 cases （3.92%） of juveniles had a history of allergies. Acute bronchitis was the main diagnosis for juveniles，with 1 656 cases （54.46%）. FLK was first used in 2 016 cases （66.43%），and 142 juvenile patients had special dosages，accounting for 4.68%. Among them，92 adverse drug reactions （ADRs） occurred，including 73 cases of gastrointestinal system disorders，10 cases of metabolic and nutritional disorders，eight cases of skin and subcutaneous tissue diseases，two cases of vascular and lymphatic disorders，and one case of systemic diseases and various reactions at the administration site. The manifestations of ADRs were mainly diarrhea，stool discoloration，and vomiting，and no serious ADRs occurred. The results of multi-factor analysis indicated that special dosages （the use of FLK）［odds ratio （OR） of 2.642， 95% confidence interval （CI） of 1.105-6.323］，combined administration： spleen aminopeptide （OR of 4.978， 95%CI of 1.200-20.655），and reason for combined administration： anti-infection （OR of 1.814， 95%CI of 1.071-3.075） were the risk factors for ADRs caused by FLK. Conclusion92 ADRs occurred among 3 035 juveniles using FLK. The incidence of ADRs caused by FLK was 3.03%，and the severity was mainly mild or moderate. Generally，the prognosis was favorable after symptomatic treatment such as drug withdrawal or dosage reduction，suggesting that FLK has good clinical safety.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

AIM To investigate the effects of different compatibility ratios and processing method on the content of rutin,isoquercetin,ferulic acid,quercetin,isotoosendanin,kaempferol,toosendanin,α-pinene,trans-anethole in the combination use of Toosendan Fructus and Foeniculi Fructus,and to explore the optimal compatibility ratio for its use.METHODS The analysis of HPLC-DAD was performed on a 30℃thermostatic ZORBAX SB C18 column(4.6 mm×250 mm,5 μm),with the mobile phase comprising of acetonitrile-0.1%phosphoric acid flowing at 1.0 mL/min in a gradient elution manner,and the use of DAD detector.SPSS 24.0 software was used to analyze the data differences.RESULTS Nine constituents showed good linear relationships within their own ranges(r≥0.999 1),whose average recoveries were 96.19%-103.13%with the RSDs of 1.86%-2.67%.Generally higher total content of nine constituents were detected in the combination use groups when Toosendan Fructus-Foeniculi Fructus were at ratios of 1 ∶ 1,1 ∶ 2,and 2 ∶ 1 than those single uses(P<0.05),and among which the 1 ∶ 1 ratio contributed the highest total content.After salt processing,decreased content of toosendanin and isotoosendanin,α-pinene and trans-anethole(P<0.05,P<0.01)),increased isoquercetin content(P<0.01),and no significant content changes of other ingredients were detected.CONCLUSION Through this method of high accuracy and good reproducibility,we learn that the combination use of Toosendan Fructus and Foeniculi Fructus promotes the dissolution of the nine constituents,and the maximum content is achieved at ratio of 1 ∶ 1.

ObjectiveTo evaluate the efficacy and safety of first-line transcatheter arterial chemoembolization （TACE） combined with targeted therapy and immunotherapy in the treatment of patients with stage Ⅱb/Ⅲa hepatocellular carcinoma （HCC） based on China Liver Cancer Staging （CNLC）. MethodsA total of 198 patients who received first-line TACE combined with targeted therapy and immunotherapy or received TACE alone from January 2015 to December 2022 in the First Affiliated Hospital of Soochow University were enrolled in this study， and after propensity score matching， there were 50 patients in combination group and 50 patients in TACE group. The Kaplan-Meier method was used to calculate median overall survival （mOS） and median progression-free survival （mPFS）. Modified Response Evaluation Criteria in Solid Tumors was used to evaluate objective response rate （ORR） and disease control rate （DCR）， and Common Terminology Criteria for Adverse Events v5.0 was used to evaluate adverse events. The chi-square test was used for comparison of categorical data between two groups； the t-test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups. The Kaplan-Meier method was used to estimate survival time and calculate 95% confidence interval （CI）， and the Log-rank test was used for comparison of mOS and mPFS between two groups. ResultsThe combination group had an mOS of 30.1 months （95%CI： 21.9‍ ‍—‍ ‍38.3）， and the TACE group had an mOS of 14.5 months （95%CI： 11.0 ‍—‍‍ ‍18.0）， with a significant difference between the two groups （χ²=17.8， P<0.001）； the combination group had an mPFS of 10.3 months （95%CI： 8.8‍ ‍—‍ ‍11.8）， and the TACE group had an mPFS of 7.1 months （95%CI： 5.8‍ — ‍8.4）， with a significant difference between the two groups （χ²=10.4， P<0.001）. There were significant differences between the combination group and the TACE group in ORR （84% vs 58%， P<0.05） and DCR （94% vs 80%， P<0.05）. There was no significant difference between the combination group and the TACE group in the incidence rate of adverse events （24% vs 16%， P=0.317）， and no adverse event-related deaths were observed in either group. ConclusionCompared with TACE alone， TACE combined with targeted therapy and immunotherapy has a better efficacy in the treatment of patients with CNLC stage Ⅱb/Ⅲa HCC， without increasing the incidence rate of severe adverse events.

Objective:To evaluate myocardial microcirculation perfusion with myocardial contrast echocardiography (MCE) in patients with acute myocardial infarction after percutaneous coronary intervention (PCI), and to explore the prognostic value of different types of myocardial microcirculation perfusion.Methods:This is a prospective cohort study. Patients with acute myocardial infarction who underwent successful PCI in Nanfang Hospital of Southern Medical University and Kanghua Hospital of Dongguan City from October 2019 to June 2021 were selected. All the enrolled patients completed MCE examination within 72 hours after PCI. According to the examination results, the patients were divided into normal microcirculation perfusion group, delayed microcirculation perfusion group, and blocked microcirculation perfusion group. Adverse cardiovascular events including all-cause death, cardiovascular death, and angina re-hospitalization were followed up, and left ventricular ejection fraction (LVEF) review results were collected at six months to one year after surgery. Kaplan-Meier survival curve was used to investigate the difference in the incidence of adverse cardiovascular events in different myocardial perfusion groups, and Cox regression analysis was used to evaluate the effect of myocardial perfusion on adverse cardiovascular events.Results:A total of 113 patients with acute myocardial infarction were included, aged (56.3±11.5) years, with 88(78%) males. There were 31 cases in the normal microcirculation perfusion group, 43 cases in the delayed microcirculation perfusion group and 39 cases in the blocked microcirculation perfusion group. LVEF was reviewed in 49 patients, and LVEF in the delayed microcirculation perfusion group was significantly improved compared with baseline at follow-up ((63.3±1.2) % vs. (58.6±1.8) %, P=0.043), and there was no statistically significant difference between the other two groups (all P>0.05). The median follow-up time was 473 days, during follow-up period 30 adverse cardiovascular events occurred. Kaplan-Meier survival curve analysis showed that there was a statistically significant difference in the incidence of adverse cardiovascular events among the three groups ( Plog-rank=0.029). Cox regression analysis showed that abnormal microcirculation perfusion (defined as delayed and blocked microcirculation perfusion) was an independent predictor of adverse cardiovascular events in patients with acute myocardial infarction after PCI ( HR=1.90, 95% CI1.16-3.12, P=0.011). Conclusions:Microcirculatory perfusion decrease or lost is common in patients with acute myocardial infarction after PCI. Timely restoration of blood flow reconstruction can save heart function when microcirculatory perfusion decreases. Microcirculatory perfusion is a predictor of adverse cardiovascular events in patients with acute myocardial infarction, and patients with poor myocardial perfusion are more likely to experience adverse cardiovascular events.

ObjectiveTo explore whether miR-375 regulates the malignant characteristics of osteosarcoma (OS) by influencing the expression of MMP13. MethodsPlasmid DNAs and miRNAs were transfected into OS cells and HEK293 cells using Lipofectamine 3000 reagent. Real-time quantitative polymerase chain reaction was performed to measure the expression of miR-375 and MMP13 in OS patients and OS cells. Western blot was performed to analyze the MMP13 protein in the patients with OS and OS cells. The targeting relationship between miR-375 and MMP13 was analyzed by luciferase assay. Migration and invasion were analysed by heal wound and transwell assays, respectively. ResultsmiR-375 expression in OS tissues was lower than that in normal tissues. The expression of MMP13 was upregulated in OS tissues. MMP13 expression was negatively correlated withmiR-375 expression in patients with OS. Migration and invasion were significantly inhibited in OS cells with the miR-375 mimic compared with OS cells with the miRNA control. MMP13 partially reversed the inhibition of migration and invasion induced by miR-375 in the OS cells. ConclusionmiR-375 attenuates migration and invasion by downregulating the expression of MMP13 in OS cells.

Pharmacokinetics of traditional Chinese medicine(TCM)is a discipline that adopts pharmacokinetic research methods and techniques under the guidance of TCM theories to elucidate the dynamic changes in the absorption,distribution,metabolism and excretion of active ingredients,active sites,single-flavour Chinese medicinal and compounded formulas of TCM in vivo.However,the sources and components of TCM are complex,and the pharmacodynamic substances and mechanisms of action of the majority of TCM are not yet clear,so the pharmacokinetic study of TCM is later than that of chemical medicines,and is far more complex than that of chemical medicines,and its development also confronts with challenges.The pharmacokinetic study of TCM originated in the 1950s and has experienced more than 70 years of development from the initial in vivo study of a single active ingredient,to the pharmacokinetic and pharmacodynamic study of active ingredients,to the pharmacokinetic study of compound and multi-component of Chinese medicine.In recent years,with the help of advanced extraction,separation and analysis technologies,gene-editing animals and cell models,multi-omics technologies,protein purification and structure analysis technologies,and artificial intelligence,etc.,the pharmacokinetics of TCM has been substantially applied in revealing and elucidating the pharmacodynamic substances and mechanisms of action of Chinese medicines,research and development of new drugs of TCM,scientific and technological upgrading of large varieties of Chinese patent medicines,as well as guiding the rational use of medicines in clinics.Pharmacokinetic studies of TCM have made remarkable breakthroughs and significant development in theory,methodology,technology and application.In this paper,the history of the development of pharmacokinetics of TCM and the progress of cutting-edge research was reviewed,with the aim of providing ideas and references for the pharmacokinetics of TCM and related research.
