Myocardial infarction （MI） refers to an acute clinical syndrome of myocardial necrosis due to persistent ischemia and hypoxia， resulting from the sharp reduction or interruption of coronary blood flow. Nuclear factor κB （NF-κB） is the key factor in inducing inflammatory response， and it is involved in the production of pro-inflammatory factors and myocardial cell apoptosis. This article systematically describes the molecular regulation mechanism of the NF-κB signaling pathway in MI， and reviews the related research on the prevention and treatment of MI through the regulation of this signaling pathway by active ingredients and compound formulas from traditional Chinese medicine （TCM）. It has been found that active ingredients from TCM， such as ginsenoside Rg3， baicalein， curcumin， tanshinone ⅡA， gambogic acid， as well as compound formulas， including Qili qiangxin capsules， Yiqi huoxue decoction， Lingbao huxin dan， Danhong injection， Baoyuan decoction combined with Taohong siwu decoction， can improve myocardial fibrosis， alleviate inflammatory responses， and inhibit cardiomyocyte apoptosis by suppressing the NF-κB signaling pathway. Thereby， they achieve the goal of preventing and treating MI.

OBJECTIVE To identify core genes associated with the treatment of coronary heart disease （CHD） with Tongmai yangxin pills， and predict their potential immunological and metabolic mechanisms. METHODS Mendelian randomization （MR） analysis was conducted using protein quantitative trait loci （pQTL） data from the UK Biobank and Icelandic，and data from genome- wide association study to screen core genes related to Tongmai yangxin pills in the treatment of CHD. Gene expression changes were further validated using transcriptomic sequencing data. Mediation analyses of immune cells and plasma metabolites were subsequently performed to explore the downstream regulatory networks of these core genes. RESULTS A total of 62 positive pQTL genes showed significant causal associations with CHD. MR analysis combined with transcriptomic sequencing validation identified three core genes FAM3D，OXT， and ENPP5-associated with Tongmai yangxin pills in the treatment of CHD. The transcriptomic sequencing results showed that after treatment with Tongmai yangxin pills， the expression levels of FAM3D and OXT were significantly reduced （P＜0.01）， while the expression level of ENPP5 was significantly increased （P＜0.05）. Mediation analyses between immune cells and plasma metabolites indicated that these genes may positively or negatively regulate CHD through immune pathways involving regulatory T cells and myeloid dendritic cells expressing CD11c and CD62L， as well as through metabolic pathways related to lipid and fatty acid metabolism， cholesterol metabolism， and bile acid metabolism. CONCLUSIONS This study identified FAM3D，OXT， and ENPP5 as core genes associated with the treatment of CHD by Tongmai yangxin pills， which may exert therapeutic effects via modulation of immune cells and plasma metabolic pathways involving fatty acids and bile acids.

OBJECTIVE To systematically evaluate the clinical efficacy of dapagliflozin in the treatment of heart failure with diabetes mellitus type 2. METHODS The clinical trials of dapagliflozin in the treatment of heart failure with diabetes mellitus type 2 were searched in Embase, PubMed, Web of Science, Cochrane Library, VIP, CNKI and Wanfang databases from the establishment of the database to March 18, 2022. The RevMan 5.3 software was used for meta-analysis, and the TSA 0.9 software was used for sequential analysis. RESULTS The 31 RCT studies meeting the criteria were finally included, involving 2 906 patients. Meta-analysis showed that compared with the control group, the experimental group significantly improved LVEF[MD=4.43, 95% CI(3.35, 5.50), P<0.000 01], total effective rate[MD=4.19, 95%CI(2.52, 6.99), P<0.000 01], and reduced NT-proBNP[MD=–451.84, 95%CI(–608.09, –295.60), P<0.000 01], LVEDD[MD=–2.74, 95%CI(–3.67, –1.82), P<0.000 01, Hb1ac[MD=–0.88, 95%CI(–1.19, –0.57), P<0.000 01], FPG[MD=–1.10, 95%CI(–1.45, –0.75), P<0.000 01], 2hPG[MD=–2.52, 95%CI(–3.37, –1.66), P<0.000 01] and the incidence of adverse reactions[MD=0.63, 95%CI(0.47, 0.83), P=0.001]. Sequential analysis showed that the effect of dapagliflozin on LVEF in patients with heart failure with type 2 diabetes was accurate, and the possibility of excluding false positive was possible. CONCLUSION The treatment of heart failure with diabetes mellitus type 2 with good efficacy and safety is achieved by dapagliflozin, but it still needs to be included in more high-quality RCT studies for further demonstration.

ObjectiveTo investigate the current status of secondary prevention of stable angina in patients with coronary heart disease in three regions of China， namely Henan Province， Xinjiang Uygur Autonomous Region， and Tianjin City， and analyze the the influencing factors. MethodsA cross-sectional study was conducted to include patients with stable angina with coronary heart disease in Henan， Tianjin and Xinjiang from August 10， 2020 to March 14， 2021. General information， traditional Chinese medicine （TCM） syndrome elements， prescriptions and other data of patients were collected， and clinical characteristics， blood pressure， blood lipid and blood glucose of patients were analyzed； the patients were divided into groups according to whether their blood pressure， blood lipid and blood glucose were up to standard. With the most common syndrome element as the main variable， region， age and gender as covariables， Logistic regression equation was incorporated to analyze the influencing factors for the patients' blood pressure， blood lipid and blood glucose being up to standard. ResultsA total of 1061 coronary heart disease patients with stable angina were included， including 658 in Henan， 210 in Xinjiang， and 193 in Tianjin. The clinical characteristics of patients in the three regions showed statistical different in age， sex， disease course， complication， blood pressure， blood lipid， blood glucose， smoking， drinking， living habits， and medication treatment （P＜0.05 or P＜0.01）. For the included patients， qi deficiency （79.55%， 844/1061） and blood stasis （39.96%， 424/1061） were the main syndrome elements. The overall compliance rate of blood pressure was 48.89% （506/1035）， blood lipids 12.68% （133/1049） and blood glucose 48.18% （504/1046）. Qi deficiency was the independent factor affecting the blood pressure of coronary heart disease patients with stable angina combined with hypertension （P = 0.029，95%CI ［1.048， 2.369］）， and the independent factors influencing the blood lipid standard of coronary heart disease patients with stable angina （P = 0.011， 95%CI ［1.133， 2.646］）， but not the independent factors affecting blood glucose standard in coronary heart disease patients with diabetes （P＞0.05）. ConclusionCoronary artery disease patients with stable angina have geographical variability in clinical characteristics and distribution of TCM syndrome elements， and the overall control of blood pressure， blood lipids， and blood glucose is poor， and qi deficiency syndrome is an independent risk factor affecting the control of blood pressure and blood lipids.

Transcatheter aortic valve replacement (TAVR) techniques have been rapidly developed in recent years. Current guidelines and studies mainly focus on aortic stenosis patients treated by transfemoral approach, but they are not completely appropriate to patients with isolated aortic regurgitation or other patients who need transapical TAVR (TA-TAVR), which affects the standardized treatment of those patients. Therefore, our team pronounced the operational standards for TA-TAVR, based on fully reviewing the literatures worldwide, combined with the opinions of experts from 15 heart centers with rich experience in carrying out TA-TAVR in China. This standard aims to provide clinicians with standardized diagnosis and treatment principles of TA-TAVR and improve the quality of TA-TAVR in China.

Objective : To explore the effects and possible mechanism of 2-hydroxy-3-methylanthraquinone (HMA) on the growth inhibition of colon cancer cells (HCT116，HT-29) ． Methods : The target of HMA was searched and analyzed by TCMSP database．The colon cancer HCT116 and HT-29 cells were cultured in vitro ，and then they were intervened with different concentrations of HMA．The effects of HMA on the viability，growth，survival ability and apoptosis of colon cancer cells were detected by CCK-8，trypan blue count，colony formation and Annexin V / PI double staining respectively．The effects of HMA on potential targets and apoptosis-regulating proteins were detected by Western blot. Results: TCMSP search analysis showed that there was HMA in Hedyotis diffusa，Scutellaria barbata and Morinda officinalis ，which contained 32 potential targets ，including apoptosis-related gene Caspase-3．Different concentrations of HMA could inhibit cells viability，growth and number of formed colonies， and induce apoptosis．The results of Western blot showed that HMA could down-regulate anti-apoptosis gene Bcl-2， up-regulate pro-apoptosis gene Bax，and promote the activation and cleavage of apoptosis-related proteins (cleaved Caspase-9，cleaved Caspase-3) ，thus promoting apoptosis． Conclusion HMA can inhibit growth and induce apoptosis of colon cancer cells，which may be related to regulating expressions of Bcl-2 ，Bax ，cleaved Caspase-9， cleaved Caspase-3 and other apoptosis proteins.

Objective:To explore the value of preablative stimulated thyroglobulin (ps-Tg) in predicting distant metastasis (DM) at the time of 131I therapy in children and adolescents with differentiated thyroid cancer (DTC). Methods:From January 2016 to March 2020, 54 children and adolescents who underwent total thyroidectomy due to DTC in Peking Union Medical College Hospital were retrospectively reviewed and divided into 2 groups according to the presence of DM or not: M0 group( n=29, 10 males, 19 females, age (16.3±3.8) years) and M1 group( n=25, 13 males, 12 females, age (12.4±4.3) years). Independent-sample t test, χ2 test (or Fisher′s exact test) and Mann-Whitney U test were used to analyze the general characteristics between the two groups. According to status of regional lymph node (RLN) at the time of 131I therapy, the two groups were further divided into M1RLN+ ( n=8) and M1RLN-( n=17), M0RLN+ ( n=5) and M0RLN-( n=24) subgroups. Mann-Whitney U test was used to analyze the different ps-Tg levels between M0 and M1, M1RLN+ and M1RLN-, as well as M0RLN+ and M0RLN-groups. The receiver operating characteristic (ROC) curve analysis was employed to obtain a cut-off value of ps-Tg as a predictor of DM. Results:Patients with DM tended to have higher ps-Tg level (medians: 406.80 μg/L vs 7.90 μg/L, U=690.000, P<0.001), younger age ( t=-3.559, P=0.001), larger tumor size ( t=3.523, P=0.001), more advanced T stage ( U=506.500, P=0.010) and more multifocality( P=0.013) in comparison with those without DM. Though ps-Tg did not significantly differ between M1RLN+ group and M1RLN-group ( U=98.500, P>0.05) or between M0RLN+ group and M0RLN-group ( U=63.000, P>0.05), the two RLN+ groups tended to hold higher medians than the two RLN-groups (18.05 vs 5.71 μg/L; 1 698.50 vs 216.40 μg/L). In order to avoid the possible influence on the ps-Tg cut-off value, 13 RLN+ samples were removed, and the area under the ROC curve was 0.946 (95% CI: 0.883-1.000). The ps-Tg level of 55.87 μg/L was established as the optimal cut-off value to distinguish M0RLN- from M1RLN-, with the sensitivity and specificity of 14/17 and 95.8%(23/24), respectively. Conclusion:Ps-Tg holds a high predictive value in identifying DM, which may be of great help in avoiding inadequate 131I treatment in children and adolescents with metastatic DTC ignored by radiological examinations.

Objective: To investigate the effect and mechanism of LncRNA ANRIL on the radiosensitivity of HCT116 cells line and nude mouse transplant tumors. Methods: The expression of LncRNA ANRIL in colorectal cancer cells was detected by qPCR. The negative control siRNA, ANRIL siRNA, miR-NC mimic, miR-195 mimic, miR-NC inhibitor and miR-195 inhibitor were transfected into HCT116 cells, and marked as negative control group, silencing ANRIL group, overexpressing miR-NC group, overexpressing miR-195 group, inhibiting miR-NC group and inhibiting miR-195 group, and the HCT116 cells without any treatment were marked as the blank control group. The clone formation assay was used to detect radiosensitivity of colorectal cancer cells, flow cytometry was used to detect apoptosis. The web site, StarBase, was used to predict the downstream miRNAs of ANRIL and dual luciferase reporter gene assay was used to further verify. Subcutaneous tumor transplantation assay was used to detect the effect of ANRIL on the growth of colorectal cancer cells after irradiation. Results: After irradiation with 2, 4, 6 and 8 Gy, the cell survival fraction of silencing ANRIL group was significantly decreased when compared with that of negative control group (P<0.05), and the radiosensitivity ratio was 1.52. The apoptosis rate of the silencing ANRIL+ 4 Gy group was significantly higher than that of the negative control+ 4 Gy group ((27.86±2.78)% vs. (12.06±1.46)%, P<0.05). The results of the experiment on nude mouse transplant tumors showed that the tumor volume in the negative control group was lower than that of the silent ANRIL group on days 13, 16, 19, 22 and 25 ((234±66) mm³, (273±63) mm³, (296±72) mm³, (321±85) mm³ and (403±94) mm³ vs. (357±79) mm³, (485±124) mm³, (617±143) mm³, (764±174) mm³ and (985±221) mm³P<0.05). MiR-195 is a target gene of ANRIL, and inhibition of miR-195 can reverse the inhibitory effect of silencing ANRIL on radiosensitivity, apoptosis and xenografts of HCT116 cells. Conclusions LncRNA ANRIL regulates the radiosensitivity of colorectal cancer cells by miR-195, which may provide a new sensitizing target for clinical colorectal cancer radiotherapy.

Objective     To report our experience with enhanced recovery after surgery (ERAS) protocol in patients undergoing transapical transcatheter aortic valve implantation (TAVI) and to determine perioperative predictors for ERAS failure. Methods     Between May 2018 and January 2019, 80 patients undergoing TAVI in our hospital were recruited. Among them, 40 patients (24 males, 16 females, aged 73.0±5.0 years) successfully received ERAS, defined as successful extubation in operating room (an ERAS group) and the other 40 patients (28 males, 12 females, aged 73.0±7.0 years, a non-ERAS group) failed to perform ERAS.  Results     Compared with the non-ERAS group, patients in the ERAS group were associated with a significantly lower incidence of postoperative complications (30.0% vs. 52.5%, P=0.04), shorter postoperative ICU stay (2.2±0.4 d vs. 4.0±4.8 d, P=0.00) and hospital stay (7.0±2.3 d vs. 9.5±4.8 d, P=0.00), and less medical cost (311±20 thousand yuan vs. 347±80 thousand yuan, P=0.00). Independent predictors of ERAS failure were poor preoperative heart function and elevated B-type natriuretic peptides.  Conclusion     ERAS protocol is feasible and effective in patients undergoing TAVI. Poor preoperative heart function is an independent predictor of failure in early extubation which, in turn, is associated with prolonged ICU and hospital stay and dramatic worsening of patient outcomes.
