Objective:To explore the effects of compound Danshen dripping pills (CDDP) and CDDP combined with transplantation of human umbilical cord blood cells (HUMNCs) on the inlfammatory response, oxidative stress, myocardial cell apoptosis and cardiac function, and also to investigate the possible mechanisms of the combined therapy in the acute myocardial infarction (AMI).
Methods:Rabbit model of AMI successfully established by ligation of the letf anterior coronary artery (LAD). Forty rabbits were randomly divided into 4 groups (n=10 per group):a control group, injected with 0.5 mL of saline in 24 h atfer AMI and then gavaged with 5 mL of saline daily;a CDDP group, injected with saline 0.5 mL atfer AMI and then gavaged with CDDP (270 mg/d) daily;a transplantation group, injected with 0.5 mL of saline contained 3 × 107 HUCBMCs [labeled with green fluorescent protein (GFP)] and then gavaged with 5 mL of saline daily;a combined group, injected with 0.5 mL of saline contained 3 × 107 HUCBMCs (labeled with GFP) and then gavaged with CDDP (270 mg/d) daily. Cardiac function index such as left ventricular fractional shorting (LVFS) and ejection fraction(LVEF) were measured by echocardiography;the pathological changes were observed by HE staining and the white blood cells in the myocardium were determined by light microscopy. hTe superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in myocardium were detected by nitrotetrazolium blue chloride (NBT) and thiobarbituric acid colorimetric measurement respectively. hTe number of transplanted cells in the myocardium was examined by GFP positive cells counted with lfuorescence microscopy.
Results:1) Compared with the control group (at 1 or 4 week), LVEF and LVFS were signiifcant improved in the CDDP group, the transplantation group and the combined groups (all P<0.05), the improvement degree of cardiac function in the combined group was the most significance. There was no significant difference between the CDDP group and the transplantation group. 2) Compared with the control group (at 1 or 4 week), the number of white blood cell, myocardial cell apoptosis ratio were decreased signiifcantly in the CDDP group, the transplantation group and the combined groups (all P<0.05), this decrease in the combined group was the most signiifcance, and there was no significant difference between the CDDP group and the transplantation group. 3) Compared with control (at 4 week), the SOD activity was increased signiifcantly, and MDA content in myocardium was decreased in the CDDP group, this change in the combined group was the most signiifcance. 4) GFP-positive cells were found to be present in the peri-myocardial infarction area in the transplantation group and the combined group at 1, 4 weeks post-transplantation. hTe number of the GFP positive cells in the combined group was more than that in the transplantation group (P<0.05).
Conclusion:The intravenous transplantation of HUMNCs combined with the CDDP in the treatment of rabbits with AMI could increase the survival rate of transplanted cells and inhibit the myocardial cell apoptosis, therefore improve the heart function. hTe possible mechanism of the combined treatment may be involved in the inhibition of the inlfammatory response and oxidative stress in the myocardium following AMI.

Objective To systematically evaluate the effects of left ventricular global longitudinal strain (GLS) determined by two dimensional speckle tracking imaging technology (2D-STI) and left ventricular ejection fraction (LVEF) on the prognosis of patients with sepsis/septic shock.Methods Databases such as the National Library of Medicine PubMed database, Dutch medical abstracts Embase, Cochrane Library, Netherlands Elsevier, Springer and China biomedical literature database (CBMdisc), China National Knowledge Internet (CNKI), Wanfang database, China science and technology journal full-text database, Vip Chinese biomedical journal database were searched from the establishment of literature database to April 2018 to study GLS, LVEF and their relationships with mortality of septic/septic shock patients. The literatures screening and data collecting were independently conducted by two researchers, and the quality of the included literature was evaluated. The sensitivity and heterogeneity analysis were performed with RevMan 5.3 software, and the combined effects were calculated. Funnel plot was used to evaluate publication bias.Results A total of 6 articles including 5 English articles and 1 Chinese article were enrolled. There were 503 patients, 333 in the survival group and 170 in the death group. The quality of the literature was high, and the Newcastle-Ottawa scale (NOS) score was 8-9. Meta-analysis showed that short-term mortality was associated with higher GLS in patients with sepsis/septic shock [standardized mean difference (SMD) = -0.47, 95％ confidence interval (95％CI) = -0.76 to -0.18, Z = 3.16,P = 0.002], and there was no significant difference in LVEF between the survival group and the death group (SMD = 0.18, 95％CI = -0.03-0.39,Z = 1.64, P = 0.10). Sensitivity analysis was carried out for each effect index by removing each document one by one, and the results showed that there was no significant change in the combined effect before and after each document, indicating that the results were stable. The funnel plot showed that the effect points of each literature were roughly in the form of "inverted funnels" with a large symmetric distribution centered on the combined effect, but the number of studies included in this study was too small, so the publication bias could not be completely excluded.Conclusion Compared with LVEF, GLS might be a more sensitive indicator for detecting myocardial dysfunction in patients with sepsis/septic shock and might have important predictive value for short-term mortality.

Objective To explore the predictive value of contrast-enhanced echocardiography com-bined with serum levels of CD137 and insulin-like growth factor binding protein 6(IGFBP-6)for cardiovascular adverse events(MACE)in elderly patients with stable coronary heart disease(CHD)after percutaneous coronary intervention(PCI).Methods A total of 108 elderly patients with stable CHD(CHD group)who visited Department of Cardiology of Changsha First Hospital from March 2020 to March 2022 were recruited in this study.They were grouped into a non-MACE group(81 cases)and a MACE group(27 cases)according to whether MACE occurred after PCI.Another 100 healthy individuals who taking physical examination during the same period served as control group.Their serum CD137 and IGFBP-6 levels were detected,and the contrast agent filling speed(β value)and maximum number of microbubbles(A value)were calculated based on the results of contrast-enhanced echocardiography.Their general clinical data were col-lected.ROC curve analysis and multivariate logistic regression analysis were used to analyze the data.Results The serum levels of CD137 and IGFBP-6 were significantly higher,while the β value and A value were obviously lower in the CHD group than the control group(P＜0.01).And the serum levels were notably higher,and the β value and A value were remarkably lower in the MACE group than the non-MACE group(P＜0.01).The AUC of cardiac ultrasound parameters βvalue and A value combined with serum CD137 and IGFBP-6 to predict MACE after PCI in CHD patients was 0.930,which was significantly higher than the AUC value of every single indicator(P＜0.01).β value,A value,CD137 and IGFBP-6 levels were all risk factors for the occurrence of MACE in CHD patients after PCI(P＜0.01).Conclusion Contrast-enhanced echocardiography,serum CD137 and IGFBP-6 levels have certain predictive value for MACE in elderly CHD patients after PCI,and combined detection has higher predictive value.

OBJECTIVE: To evaluate the application of heparin-binding protein (HBP) in diagnosis of sepsis in adult patients. METHODS: An extensive search for the Chinese and English literatures from the PubMed, Embase, the Cochrane Library, Wanfang data, CNKI and VIP up to July 2019 was performed. The articles regarding HBP for the diagnosing of sepsis in adult patients were enrolled. Two researchers independently extracted related literature. The quality of the studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. Meta-Disc 1.4 and STATA 12.0 were used for Meta-analysis. The pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic odds ratio (DOR) were calculated. Summary receiver operating characteristic (SROC) curves and area under the curve (AUC) were used to evaluate the diagnostic performance of HBP for sepsis. Deek funnel plot was used to detect publication bias. RESULTS: A total of 10 studies with 1 884 patients were included in this Meta-analysis. The quality of the literature was relatively moderate. HBP in plasma were detected by enzyme linked immunosorbent assay (ELISA) in all studies. The studies showed substantial heterogeneity, and random effect model was used for Meta-analysis. The pooled sensitivity, specificity, PLR, NLR, and DOR were 0.80 [95% confidence interval (95%CI) was 0.77-0.83], 0.80 (95%CI was 0.78-0.82), 3.96 (95%CI was 2.45-6.41), 0.28 (95%CI was 0.20-0.39) and 14.63 (95%CI was 6.83-31.30) respectively. The pooled AUC was 0.86 and the Cochran-Q was 0.79. To explore the potential sources of heterogeneity, subgroup analyses were performed based on the severity of the disease, diagnostic criteria and region. However, the results indicated that no methodological covariates affected the diagnostic accuracy of HBP, indicating that there was still unexplained heterogeneity. In addition, the sensitivity analysis by removing individual studies were performed. No outlier study was identified and the results were relatively stable and reliable. Deek funnel plot showed little publication bias. CONCLUSIONS There is preferable value of HBP for diagnosis of sepsis in adult patients. However, it needs to be further confirmed by large multicenter studies.
