Objective To explore the prognostic impact of Qili Qiangxin capsules(QLQX)in patients with ST-segment elevation myocardial infarction(STEMI).Methods Retrospective collecting the clinical data of STEMI patients treated at PingAn Hospital affiliated to Hebei Medical University from January 2020 to January 2022,divided into QLQX group and non-QLQX group according to treatment plan.Follow-up patients for 1 year,with the main endpoint being major adverse cardiovascular and cerebrovascular events(MACCEs)at 30 d and 1 year;The secondary endpoints were cardiogenic death,myocardial reinfarction,emergency coronary revascularization,stroke,and major bleeding at 30 d and 1 year,as well as severe STEMI complications(30 d),re-admission due to heart failure(1 year),and all-cause mortality(1 year).Results A total of 210 STEMI patients were included(125 in the QLQX group and 85 in the non QLQX group).Univariate or Kaplan Meier analysis showed that the MACCE,cardiogenic death,malignant arrhythmia at 30 d,myocardial reinfarction,re-admission due to heart failure,and all-cause mortality rates in the QLQX group were significantly lower than those in the non QLQX group at 30 d and 1 year(P＜0.05),while there were no significant differences in the incidence of other observed endpoint events between the two groups(P＞0.05).In addition,QLQX may be a protective factor for MACCEs in STEMI patients(30 d:HR=0.157,95％CI 0.032 to 0.756,P=0.021;1 year:HR=0.208,95％CI 0.087 to 0.497,P=0.014).Conclusion QLQX adjuvant therapy may improve MACCEs in STEMI patients.

Objective:The transjugular or transfemoral approach is used as a common method for hepatic venous pressure gradient (HVPG) measurement in current practice. This study aims to confirm the safety and effectiveness of measuring HVPG via the forearm venous approach.Methods:Prospective recruitment was conducted for patients with cirrhosis who underwent HVPG measurement via the forearm venous approach at six hospitals in China and Japan from September 2020 to December 2020. Patients' clinical baseline information and HVPG measurement data were collected. The right median cubital vein or basilic vein approach for all enrolled patients was selected. The HVPG standard process was used to measure pressure. Research data were analyzed using SPSS 22.0 statistical software. Quantitative data were used to represent medians (interquartile ranges), while qualitative data were used to represent frequency and rates. The correlation between two sets of data was analyzed using Pearson correlation analysis.Results:A total of 43 cases were enrolled in this study. Of these, 41 (95.3%) successfully underwent HVPG measurement via the forearm venous approach. None of the patients had any serious complications. The median operation time for HVPG detection via forearm vein was 18.0 minutes (12.3~38.8 minutes). This study confirmed that HVPG was positively closely related to Child-Pugh score ( r = 0.47, P = 0.002), albumin-bilirubin score ( r = 0.37, P = 0.001), Lok index ( r = 0.36, P = 0.02), liver stiffness ( r = 0.58, P = 0.01), and spleen stiffness ( r = 0.77, P = 0.01), while negatively correlated with albumin ( r = -0.42, P = 0.006). Conclusion:The results of this multi-centre retrospective study suggest that HVPG measurement via the forearm venous approach is safe and feasible.

Aim To investigate the effects of naringenin on atherosclerotic plaque extracellular matrix remodeling and plaque stability.Methods Murine vascular smooth muscle cells were isolated and treated with various doges of naringenin.ApoE-/-mice were fed with high-fat diet and received naringenin by lavage for 16 weeks.Intraplaque nec-rotic core,contents of collagen and fibrous cap thickness were measured by Sirius red-Haematoxylin staining.Elastin was detected by Van Gieson staining.Matrix metalloproteinase(MMP)activity was determined by gelatin zymography and fluorescence-gelatin staining.Results Naringenin(50 μmol/L)increased signal tansducer and activator of transciption 6(STAT6)phosphorylation and promoted tissue inhibitor of metalloproteinase-3(TIMP-3)expression by 3.1-fold(P＜0.001).After naringenin(80 mg/kg)treatment,compared with the control group,the area of plaque necrotic core in aor-tic root decreased by 53％(P＜0.01),the thickness of fibrous caps increased by nearly 50％(P＜0.05),and the degree of elastic fiber degradation decreased.At the same time,naringenin promoted the expression of TIMP-3 in plaques,and corre-spondingly reduced the activity of MMP in plaques.Lentivirus mediated inhibition of TIMP-3 expression in vivo could reduce the protective effect of naringenin on plaque stability.Conclusion Naringin can increase the expression of TIMP-3 in smooth muscle cells,improve the composition of extracellular matrix,and promote the stability of atherosclerotic plaque.

Aim To study the effect of maternal high-fat diet during pregnancy on endothelial to mesenchymal transition of aortic vessels in adult offspring.Methods The pregnant mice were randomly divided into normal diet group and high-fat diet group,and the offspring mice were fed normally for 16 weeks after the mother gave birth.Western blot and RT-qPCR were used to detect the expression and transcription of related proteins,and immunofluorescence and im-munohistochemical staining were used for pathological analysis.Results Compared with the offspring of maternal nor-mal diet during pregnancy,the expressions of vascular inflammatory factors,macrophage infiltration,monocyte-endothelium adhesion were significantly increased in the offspring of maternal high-fat diet(OHF)during pregnancy(P＜0.05).Vas-cular endothelial nitric oxide synthase(eNOS)activity,nitric oxide(NO)level were dramatically reduced(P＜0.05).Immunofluorescence results showed reduced endothelial cell marker CD31 and increased mesenchymal marker α-smooth muscle actin(α-SMA)in OHF.Western blot analysis further confirmed the results,which showed that maternal high fat diet reduced vascular endothelial-cadherin(VE-cadherin)and CD31 and increased α-SMA and Vimentin in the offspring(P＜0.05).The maternal high fat diet increased the extracellular matrix protein disposition and transforming growth factor beta(TGF-β)/Smad signaling in endothelium(P＜0.05).Moreover,the maternal high fat diet reduced Kruppel-like factor 2(KLF2)expression by 76％in mRNA level and 59％in protein level(P＜0.05).Conclusion Maternal high-fat diet during pregnancy lead to a transition of endothelial to mesenchyme in the offspring aorta.The results provide a clue for prevention of vascular disease in early stage.

Objective　To explore the application of factorial design in field trapping experiments for flies, and to provide more ideas for screening the best fly control method. Methods　A 2×2 factorial design was used to analyze the main effects of the height of the fly cage (hanging fly cage, standing fly cage) and the type of bait (commercial bait, smelly tofu bait), and the interaction between the two factors. The fly trapping methods were divided into four combinations: hanging fly cage and commercial bait, hanging fly cage and smelly tofu bait, standing fly cage and commercial bait, standing fly cage and smelly tofu bait. The experiment was repeated 7 times for each combination and carried out according to the National Vector Biological Surveillance Implementation Plan. The best fly trapping method was identified by factorial design analysis of variance. Results　A total of 2 296 flies were trapped in this study, with a cumulative deployment of 28 traps in the field, resulting in an average total density of 82.0 flies per cage. Among them, the number of flies attracted by the combination of standing fly cage and smelly tofu was the largest, accounting for 44.16% (1 014/2 296) of the total number of flies caught, with an average fly density of 144.8 flies per trap. This was followed by the combination of hanging fly cage and smelly tofu, hanging fly trap and commercial bait, and standing fly cage and commercial bait, accounting for 42.73% (981/2 296), 8.71% (200/2 296), and 4.40% (101/2 296) of the total, with average fly densities of 140.1, 28.6, and 14.4 flies per trap, respectively. The differences in field fly density among different trapping methods were statistically significant (F=49.441, P<0.001), and the differences in fly population composition were also statistically significant (χ2=259.980, P<0.001). The main effect of trap height was not significant (F=0.223, P=0.641), while the main effect of bait type was significant (F=147.206, P<0.001), and the interaction effect between trap height and bait type was not significant (F=0.894, P=0.354). Conclusions　Compared with the single-factor design method, the factorial design method can not only analyze the main effects of each factor but also the interactions between the factors. The combination of standing fly cage and smelly tofu is preferred to have a better fly control effect.

Objective To evaluate the role of preoperative serological indexes in predicting long-term survival and tumor recurrence of hepatocellular carcinoma (HCC) patients after liver transplantation, aiming to explore its significance in expanding the Milan criteria. Methods Clinical data of 669 recipients undergoing liver transplantation for HCC were retrospectively analyzed. The optimal cut-off value was calculated by the receiver operating characteristic (ROC) curve. The risk factors affecting the overall survival and recurrence-free survival rates of HCC patients after liver transplantation were identified by univariate and multivariate regression analyses. The correlation between preoperative serum liver enzymes and pathological characteristics in HCC patients was analyzed. The predictive values of alpha-fetoprotein (AFP) combined with γ -glutamyl transferase (GGT) and different liver transplant criteria for the survival and recurrence of HCC patients after liver transplantation were compared. Results Exceeded Milan criteria, total tumor diameter (TTD) > 8 cm, AFP > 200 ng/mL and GGT > 84 U/L were the independent risk factors for the overall survival and recurrence-free survival rates of HCC patients after liver transplantation (all P < 0.05). Correlation analysis showed that preoperative serum GGT level was correlated with TTD, number of tumor, venous invasion, microsatellite lesions, capsular invasion, tumor, node, metastasis (TNM) stage, Child-Pugh score and exceeded Milan criteria (all P < 0.05). Milan-AFP-GGT-TTD (M-AGT) criteria were proposed by combining Milan criteria, TTD with serum liver enzyme indexes (AFP and GGT). The 5-year overall survival and recurrence-free survival rates of HCC recipients who met the M-AGT criteria (111 cases of exceeded Milan criteria) were significantly higher than those who met Hangzhou criteria (both P < 0.05), whereas had no significant difference from their counterparts who met the University of California at San Francisco (UCSF) criteria (both P > 0.05). Conclusions Preoperative serological indexes of AFP and GGT could effectively predict the long-term survival and tumor recurrence of HCC patients after liver transplantation. Establishing the M-AGT criteria based on serological indexes contributes to expanding the Milan criteria, which is convenient and feasible.

Objective:To explore the application of effect of healthcare failure mode and effect analysis (HFMEA) in emergency waiting risk management.Methods:From May 2020 to April 2021, totally 87 902 emergency waiting patients from the First Affiliated Hospital of Anhui Medical University were assigned to control group by cluster sampling method. From May 2021 to April 2022, 80 594 emergency waiting patients were assigned to observed group. The patients in the control group received routine emergency waiting of itinerant management mode. In contrast, the patients in the observed group received emergency waiting risk management mode based on HFMEA. The process risk priority number (RPN) and waiting risk management index between two groups were compared.Results:The mean RPN of the observed group was (98.48 ± 8.27) points, significantly lower than that of the control group (251.27 ± 16.95) points. The nurses′ pre-identification rates of changes in the condition and adverse reaction in the observed group were 10.77%(8680/80 594) and 13.37%(10 775/80 594), which were higher than those in the control group, 5.77%(5072/87 902) and 8.12%(7134/87 902), the differences were statistically significant ( χ2 values were 1402.32 and 1221.66, all P<0.05). Conclusions:The application of HFMEA to optimize the emergency waiting management process can effectively reduce the risk of emergency waiting and improve the quality of emergency waiting management.

Objective:To investigate the safety and feasibility of the CHESS endoscpic ruler (CHESS ruler), and the consistency between the measured values and the interpretation values by endoscopic physician experience.Methods:From January 2021 to January 2022, a total of 105 liver cirrhosis patients with portal hypertension were prospectively enrolled from General Hospital, Xixia Branch Hospital, Ningnan Hospital of People′s Hospital of Ningxia Hui Autonomous Region (29 cases), and the First People′s Hospital of Yinchuan (25 cases), General Hospital of Ningxia Medical University (18 cases), Wuzhong People′s Hospital (10 cases), the Fifth People′s Hospital of Ningxia Hui Autonomous Region (10 cases), Shizuishan Second People′s Hospital (6 cases), Yinchuan Second People′s Hospital (5 cases), and Zhongwei People′s Hospital (2 cases) 8 hospitals. The clinical characteristics of all the patients, including gender, age, nationality, etiolog of liver cirrhosis, and Child-Pugh classification of liver function were recorded. A big gastroesophageal varices was defined as diameter of varices ≥5 mm. Endoscopist (associated chief physician) performed gastroscopy according to the routine gastroscopy procedures, and the diameter of the biggest esophageal varices was measured by experience and images were collected, and then objective measurement was with the CHESS ruler and images were collected. The diameter of esophageal varices of 10 randomly selected patients (random number table method) was determined by 6 endoscopists (attending physician or associated chief physician) with experience or measured by CHESS ruler. Kappa test was used to test the consistency in the diameter of esophageal varices between measured values by CHESS ruler and the interpretation values by endoscopic physician experience.Results:Among 105 liver cirrhosis patients with portal hypertension, male 65 cases and female 40 cases, aged (54.8±12.2) years old, Han nationality 82 cases, Hui nationality 21 cases and Mongolian nationality 2 cases. The etiology of liver cirrhosis included chronic hepatitis B (79 cases), alcoholic liver disease (7 cases), autoimmune hepatitis (7 cases), chronic hepatitis C (2 cases), and other etiology (10 cases). Liver function of 32 cases was Child-Pugh A, Child-Pugh B 57 cases, and Child-Pugh C 16 cases. All 105 liver cirrhosis patients with cirrhotic portal hypertension were successfully measured the diameter of gastroesophageal varices by CHESS ruler, and the success rate of application of CHESS ruler was 100.0% (105/105). The procedure time from the CHESS ruler into the body to the exit of the body after measurement was (3.50±2.55) min. No complications happened in all the patients during measurement. Among 105 liver cirrhosis patients with cirrhotic portal hypertension, 96 cases (91.4%) were recognized as big gastroesophageal varices by the endoscopists. Totally 93 cases (88.6%) were considered as big gastroesophageal varices by CHESS ruler. Eight cases were recognized as big gastroesophageal varices by the endoscopist, however not by the CHESS ruler; 5 cases were recognized as big gastroesophageal varices by the CHESS ruler, but not by the endoscopists; 4 cases were not recognized as big gastroesophageal varices both by the endoscopists and CHESS ruler; 88 cases were recognized as big gastroesophageal varices both by the endoscopists and CHESS ruler. The missed diagnostic rate of big gastroesophageal varices by the endoscopists experience was 5.4% (5/93), and the Kappa value of consistency coefficient between the measurement by the CHESS ruler and the interpretation by endoscopists experience was 0.31 (95% confidence interval 0.03 to 0.60). The overall Kappa value of consistency coefficient by 6 endoscopists measured by CHESS ruler in big gastroesophageal varices diagnosis was 0.77 (95% confidence interval 0.61 to 0.93).Conclusion:As an objective measurement tool, CHESS ruler can make up for the deficiency of subjective judgment by endoscopists, accurately measure the diameter of gastroesophageal varices, and is highly feasible and safe.

Objective    To investigate the surgical strategies and clinical efficacy of transmitral septal myectomy in the treatment of recurrent left ventricular outflow tract obstruction (LVOTO) after alcohol septal ablation. Methods    The clinical data of patients with recurrent LVOTO after alcohol septal ablation from July 2020 to July 2021 in the Department of Cardiac Surgery, Guangdong Provincial People's Hospital were retrospectively analyzed. Patients were preoperatively evaluated by echocardiography, cardiac magnetic resonance imaging, cardiac computed tomography, 3D modeling and printing technology. A personalized surgical strategy was preoperatively developed according to multimodality imaging assessment, while visual exploration was performed on the digital model and simulated surgical resection was performed on the printed model. Results     Two female patients were enrolled, aged 62 years and 64 years, respectively. Totally endoscopic transmitral extended myectomy was successfully performed on both patients with aortic cross-clamping time of 96 min and 85 min, respectively. LVOTO was relieved immediately (subaortic peak pressure gradient decreased from 100 mm Hg to 4 mm Hg and from 84 mm Hg to 6 mm Hg, respectively) and the mitral regurgitation significantly improved after the procedure. No patient had complete atrioventricular block or required permanent pacemaker implantation. The patients were discharged uneventfully without postoperative complications. Conclusion    Personalized totally endoscopic transmitral extended myectomy combined with multimodality imaging assessment and 3D modeling and printing has an acceptable clinical effect in patients with recurrent LVOTO after alcohol septal ablation. The procedure can precisely resect the hypertrophic septal myocardium while avoiding serious complications such as septal perforation or complete atrioventricular block.
