The morphological characteristics and pathological progression of vulnerable plaques in atherosclerosis （AS） exhibit a high degree of similarity to the concept of "abscesses and ulcers" in traditional Chinese medicine （TCM）. Therefore， vulnerable atherosclerotic plaques can be analogized as "abscesses and ulcers within the vessels"， for which deficiency， stasis and toxin constitute the core pathogenesis. The pathological evolution progresses through three sequential stages， deficiency leading to pathological substances， with phlegm and stasis accumulating into a mass； the mass transforming into putridity， with internal decay and external thinning； putridity brewing toxin， and toxin accumulation threatening rupture， ultimately resulting in plaque instability. Accordingly， a stage-specific treatment strategy is established. In the early stage， it is suggested to supplement deficiency， resolve the mass， dissipate stasis， and prevent putridity， using Liujunzi Decoction （六君子汤） combined with Danshen Decoction （丹参饮） with modifications. In the middle stage， the treatment should focus on transforming putridity to generate new tissue， and rectifying healthy qi to consolidate the body， with modified Tuoli Xiaodu Powder （托里消毒散）. In the late stage， the treatment principle is clearing and resolving putridity toxin， cooling the blood， and preventing ulcerative rupture， using modified Simiao Yong'an Decoction （四妙勇安汤） combined with Xijiao Dihuang Decoction （犀角地黄汤）.

This paper summarizes the clinical experience in treating children adenoid hypertrophy using the "opening the orifices and regulating qi method". It is considered that the pathogenesis of adenoid hypertrophy in children is rooted in dysfunction of zangfu （脏腑） organs， with binding of phlegm and stasis as the branch. Obstruction of the cervical passes and rebellious， chaotic qi flow run through the entire course of the disease. The "opening the orifices and regulating qi method" is proposed， which emphasizes the regulation of the lung， spleen， liver， and stomach. By opening the cervical passes， regulating zangfu organs， and eliminating phlegm and stasis to harmonize the ascent and descent of qi， a comprehensive application of external traditional Chinese medicine （TCM） therapies， such as acupuncture， umbilical moxibustion with medicinals， collateral bloodletting， and sole therapy， is utilized. Addressing both root and branch causes， this approach provides new perspectives for treating children adenoid hypertrophy using external TCM therapies.

ObjectiveTo investigate the correlation between iron metabolism parameters and various syndrome types of unstable angina pectoris （UAP）. MethodsA cross-sectional study was conducted from October 2021 to October 2023， encompassing 213 patients diagnosed with UAP at Xiyuan Hospital of Chinese Academy of Chinese Medical Sciences. Additionally， 30 healthy individuals were selected as control cases. Single-factor analysis was used to investigate the differences in clinical data among different Traditional Chinese Medicine （TCM） syndrome types of UAP and their correlation with iron metabolism indices. The study conducted a comparative analysis of the aforementioned clinical data among patients with and without heat-toxic and blood-stasis syndrome. Logistic regression was used to analyze the correlation between TCM syndrome types and related factors. The receiver operator characteristic （ROC） curve was employed to assess the predictive value of iron metabolism indices， along with their sensitivity and specificity. ResultsCompared to those in the control group， serum iron （SI） and serum ferritin （SF） levels were significantly increased in the UAP group （P<0.01）， while transferrin （TRF） and total iron binding capacity （TIBC） levels were decreased （P<0.01）. However， there was no significant difference in unsaturated iron binding capacity （UIBC）. Multivariate binary Logistic regression analysis identified apolipoprotein A1 （ApoA1）， homocysteine （HCY）， high-sensitivity C-reactive protein （hs-CRP）， and SF as independent influencing factors for the UAP patients （P<0.05， P<0.01）. Additionally， statistically significant differences were observed in SI， SF， TRF， and TIBC among 213 patients with different TCM types （P<0.01）. Patients with heat-toxic and blood-stasis syndrome had higher SI and SF values than those without the syndrome （P<0.01）， while their TIBC and TRF values were lower （P<0.01）. Multivariate binary logistic regression analysis showed that SI and LDL-C levels were closely associated with the differentiation of heat-toxic and blood-stasis syndrome. ConclusionUAP patients often experience iron metabolism disorders， and the heat-toxic and blood-stasis syndrome are significantly correlated with iron metabolism parameters. The SI and LDL-C levels have high specificity and sensitivity in diagnosing heat-toxic and blood-stasis syndrome.

Objective To discuss the application of CT myocardial perfusion imaging(CT-MPI)combined with plaque quantification technique in assessing reperfusion injury in patients with myocardial ischemia.Methods The clinical data of 100 patients with myocardial ischemia,who were admitted to the People's Hospital of Xinjiang Uygur Autonomous Region of China from June 2019 to June 2024,were retrospectively analyzed.CT-MPI and plaque quantification technique examination were performed in all patients before percutaneous coronary intervention(PCI).According to the presence or absence of reperfusion injury after PCI,the patients were divided into non-injury group(n=38)and injury group(n=62).The CT-MPI parameters,including time-to-peak(TTP),myocardial blood flow(MBF)and myocardial blood volume(MBV),and the plaque quantification technique parameters,including eccentricity index(EI),remodeling index(RI),calcified plaque volume(CPV),minimum lumen area(MLA),narrowness degree(ND),non-calcified plaque volume(NCPV),total plaque volume(TPV)and plaque length(PL),were compared between the two groups.Receiver operating characteristic(ROC)curve was used to analyze the value of CT-MPI and plaque quantification technique in assessing reperfusion injury in patients with myocardial ischemia,and logistic regression analysis was used to determine the factors influencing reperfusion injury.Results TTP in the injury group was longer than that in the non-injury group,while MBF and MBV in the injury group were lower than those in the non-injury group(all P＜0.05).No statistically significant differences in El,RI,CPV and MLA existed between the two groups(all P＞0.05).ND,NCPV,TPV and PL in the injury group were higher than those in the non-injury group(P＜0.001).ROC curve analysis showed that the area under ROC curve(AUC)of combination use of TTP MBF,MBV,ND,NCPV,TPV and PL for evaluating reperfusion injury in patients with myocardial ischemia was 0.914,which was higher than the values obtained by the separate evaluation of the above seven indicators,and the results were 0.781,0.784,0.760,0.791,0.775,0.792 and 0.798 respectively(all P＜0.05).Logistic regression analysis revealed that TTP,MBF,MBV,ND,NCPV,TPV and PL were the risk factors for reperfusion injury in patients with myocardial ischemia(all P＜0.05).Conclusion CT-MPI combined with plaque quantification technique can effectively evaluate the reperfusion injury in patients with myocardial ischemia,providing important reference for the diagnosis and treatment of reperfusion injury,therefore,it has high clinical application value.

Refractory angina is characterized by recurrent and persistent angina with a duration of not less than three months， which is related to reversible ischemia and hypoxia caused by coronary stenosis and obstruction. It mainly involves obstructive coronary artery disease and non-obstructive coronary artery disease with coronary artery spasm and coronary microvascular dysfunction. “Stasis and toxin” play an important role in the pathogenesis of cardiovascular diseases. The pathogenesis of stasis and toxin is stubborn filthy turbidity featured by slow accumulation and sudden onset，and rapid changes，which coincides with the characteristics of refractory angina which is complex and changeable，prolonged and difficult to cure. The pathogenesis of refractory angina involves a combination of underlying deficiency and excessive manifestation， with "stasis and toxin" playing a crucial role as an important pathological factor in the whole process of refractory angina. Traditional Chinese medicine （TCM） employs a holistic approach known as "activating blood circulation and removing toxins"， which is supplemented by various methods to tonify Qi and warm Yang， nourish the kidneys and invigorate the spleen， clear heat and transform phlegm. This approach applies anti-inflammatory measures， regulates lipid metabolism， inhibits oxidative stress and thrombus formation， protects endothelial function in blood vessels， as well as establishes collateral circulation for the prevention and treatment of refractory angina. Therefore，based on the theory of "stasis and toxin"，combined with TCM theory and modern medical research，this paper discusses the pathogenesis of refractory angina and the prevention and treatment strategy of TCM，and elucidates the reasons for the difficulty in curing refractory angina and the relationship between refractory angina and common angina pectoris，coronary microvascular dysfunction，coronary artery spasm and obstructive coronary artery disease，hoping to provide certain theoretical basis and clinical ideas for the prevention and treatment of refractory angina with TCM.

Talents are the main force for the development of traditional Chinese medicine（TCM）， and the construction of TCM talents and the reformation of talent evaluation system are essential to promote the inheritance and innovation of TCM. At present， we are still exploring and developing in the fields of the formulation， implementation and evaluation indicators of TCM talent evaluation system. However， there are shortcomings and difficulties. For instance， insufficient stratification in the evaluation， excessive emphasis on the quantity of achievements， neglecting the quality of the achievements and the actual contribution， imperfect assessment indicators， and the weak characteristics of TCM. Therefore， national ministries and commissions have jointly issued a document requesting to break the four only and set a new standard， in order to promote the construction of a scientific and technological talent evaluation system oriented by innovation value， ability and contribution. For the evaluation of TCM clinical talents， China Association for Science and Technology commissioned China Association of Chinese Medicine to build the China Clinical Cases Library of TCM（CCCL-TCM）， which aims at collecting the most authoritative and representative TCM clinical cases and exploring the advantages of applying clinical cases as masterpiece of achievement in TCM clinical talents evaluation. CCCL-TCM can promote the construction of a talent evaluation system that is more in line with the development characteristics of TCM industry， and to carry out relevant pilot in TCM colleges and institutions across the country in order to promote the reformation of TCM talent evaluation system.

OBJECTIVE To study the triterpenoid saponins from Anemone rivularis var. flore-minore and their antitumor activities.

Compounds 3，4，6-9 displayed inhibitory activities on the proliferation of tumor cells to different extent ，and compound 7 had the strongest activity ；compound 7 induced the apoptosis of U 87MG cell so as to inhibit the proliferation of cancer cells in a time-dependent manner. CONCLUSIONS The obtained 16 saponins are all identified as oleanolane-type ，among which compound 1 is a new compound. The monodesmosidic saponins ，the sugar chain of which attached at C- 3 and a free carboxyl at C- 28， possess stronger antitumor activity than others.

ObjectiveTo investigate the protective effect of Zhizi prescription （ZZP） on carbon tetrachloride （CCl₄）-induced acute and subacute liver injury and its mechanism. MethodAcute and subacute liver injury animal models were induced. C57 mice were randomly divided into a normal group， model group， obeccholic acid group， ZZP high-dose （0.5 g·kg^-1） group， and ZZP low-dose （0.25 g·kg^-1） group. According to the experiment design， the serum and liver tissue of mice were collected after the last administration. Hematoxylin-eosin （HE） and Sirius staining was used to observe the liver pathological changes. Serum alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， total bilirubin （TBIL）， liver homogenate hydroxyproline （Hyp）， malondialdehyde （MDA）， and superoxide dismutase （SOD） levels were determined by kit. The levels of tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6） in the liver tissue were determined by enzyme-linked immunosorbent assay （ELISA）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expressions of collagen 1A1 （Col1a1）， collagen 3A1 （Col3a1）， fibronectin （FN）， transforming growth factor β receptor Ⅱ （Tgfbr2） and α-smooth muscle actin （α-SMA） in the liver tissue. ResultIn terms of the acute liver injury， as compared with the normal group， the levels of ALT， AST， TBIL and MDA in the model group were significantly increased （P<0.01）， while the activity of liver SOD was significantly decreased （P<0.01）. Compared with model group， the ZZP high-dose and low-dose groups both significantly reduced the degree of liver cell injury， and protected the acute liver injury induced by CCl₄. The ZZP high-dose group had a better effect than the ZZP low-dose group. In terms of the subacute liver injury， the levels of ALT， AST， MDA，TNF-α and IL-6 in the model group were significantly increased （P<0.01）， while the activity of liver SOD was significantly decreased （P<0.01）. As compared with the model group， liver Hyp content in the ZZP high-dose and low-dose groups was significantly decreased （P<0.01）， and the collagen deposition in liver of both groups was significantly reduced. The ZZP high-dose group also significantly down-regulated the mRNA expressions of α-SMA， Col1a1， Col3a1， FN， and Tgfbr2 in the liver of mice （P<0.05， P<0.01）. ConclusionZZP effectively protects the acute and subacute liver injury induced by CCl₄， and the protective effect is proportional to its concentration. The mechanism may be related to the increase of the activity of antioxidant enzymes in the liver tissue， the decrease of the level of lipid peroxidation， and the inhibition of inflammatory response， thus reducing collagen deposition and improving early liver fibrosis.
