Objective To observe the factors affecting inadequate ST-segment resolution in patients with acute ST-segment elevation myocardial infarction after emergency percutaneous coronary intervention (PCI). Methods The patients with acute ST-segment elevation myocardial infarction undergoing emergency PCI were enrolled for study. According to the ratio of ST-segment resolution, 186 cases were divided into inadequate ST-segment resolution group (54 cases) and relatively adequate ST-segment resolution (132 cases). Clinical data of two groups were compared. The single factor and multiple Logistic regression analysis were performed to determine the factors influencing inadequate ST-segment resolution. Results Pre-infarction angina was protective factor of inadequate ST-segment resolution after emergency PCI (OR=0.361, 95%CI 0.131-0.994, P<0.05). Anterior myocardial infarction, attack-to-balloon time, Killip classification and white blood cell counts were risk factors of inadequate ST-segment resolution (OR=2.389, 95%CI 1.194-4.781;OR=1.655, 95% CI 1.082-2.532; OR=1.319, 95% CI 1.026-1.695; OR=1.184, 95% CI 1.004-1.396, P<0.05). Conclusions Patients with pre-infarction angina could reduce the risk of inadequate ST-segment resolution after PCI. Patients with anterior myocardial infarction,long attack-to-balloon time, Killip classification≥2 and high blood cell counts could increase the risk of inadequate ST-segment resolution, and earlier and more active clinical intervention should be taken.

OBJECTIVE: To investigate whether the water extractives of regulating qi and blood prescription (WQBP) had effects on early atherosclerosis of apolipoprotein E-deficient mice (ApoE-mice) at the age of 19 weeks or not, and to explore the possible mechanisms. METHODS: Forty ApoE-mice, six weeks of age, were given high-fat diet and randomly divided into four groups: high-dose WQBP-treated group (360 mg/kg), low-dose WQBP-treated group (72 mg/kg), simvastatin-treated group (25 mg/kg) and untreated group, with ten mice in each group. Meanwhile, ten C57BL/6 mice of same genetic background were allocated to normal control group. Mice in the high- and low-dose WQBP-treated groups and simvastatin-treated group were administered with corresponding drugs from the 15 to 19 weeks. Mice in the untreated and normal control groups were administered with isovolumic water. Sacrificed at 19 weeks, the level of blood-lipid, the plaque construction, plaque integral, and the contents of plaque macrophages and vessel smooth muscle cells of the mice were analyzed by immunohistochemical method and a computer picture processing system. RESULTS: Compared to the untreated group, high-dose WQBP group could obviously decrease the level of low-density lipoprotein cholesterol (LDL-C). Simvastatin group could decrease the levels of LDL-C and total cholesterol (TC) (P<0.01). In high-dose WQBP-treated group and simvastatin-treated group, the thickness of fiber cap and the quantities of vessel smooth muscle cells increased (P<0.05), the quantities of plaque macrophages and the ratio of lipid and plaque reduced (P<0.01). CONCLUSION: WQBP and simvastatin can interfere in early atherosclerosis of ApoE-mice, attenuate and stabilize plaque in some extent. The mechanisms may include adjusting blood lipid, decreasing macrophage number and increasing the quantities of vessel smooth muscle cells.

Objective To explore the effects of walking exercise on glycometabolism,dynamic blood pressure and the quality of life of patients with both hypertension and type 2 diabetes on the basis of conventional drug treatment.Methods Sixty-two patients with both hypertension and diabetes who could support taking walking exercise of more than 5,000 steps/d were randomly divided into a walking exercise group (32 cases) and a control group (30 cases).Both groups were given conventional drug treatment (including valsartan,acarbose and metformin).Those in the walking exercise group took more than 10,000 steps/d of aerobic exercise while the patients in the control group were just given normal community care.This continued for a period of 3 months.Fasting plasma glucose (FPG),glycated hemoglobin-A1C (HbA1c),fasting insulin (FINS),the homeostasis model of assessment for insulin resistence index (HOMA-IR),the homeostasis model of assessment for insulin sensitivity (HOMA-IS),dynamic blood pressure parameters and quality of life were observed.Results In the walking exercise group,the FPG,HbA1c,FINS,HOMA-IR,HOMA-IS,dynamic blood pressure and quality of life indicators were all significantly different after 3 months of daily walking exercise compared with either baseline or the control group.Conclusion Accompanied by conventional drug therapy,10,000 steps/d of walking exercise can improve the glucose metabolism,dynamic blood pressure and quality of life of patients suffering from mild hypertension and type 2 diabetes.

Objective: To investigate the efficacy of microwave ablation in the treatment of hepatocellular carcinoma (HCC) within the Milan criteria and to investigate the differences in clinical efficacy of microwave ablation in tumors with different sizes. Methods: A retrospective analysis was performed on the clinical data of the patients with HCC within the Milan criteria who received microwave ablation in our hospital from January 2011 to January 2013. The complete ablation rate, incidence rate of major complications, recurrence rate, and overall survival rate were analyzed and the treatment outcomes were compared between two groups with different tumors sizes. The patients were followed up for 3.4-61.8 months. The Kaplan-Meier method was used to calculate overall survival rate, local recurrence rate, and distant recurrence rate. Comparison of rates between groups was made by the chi-square test and comparison of survival rates between groups was made by the log-rank test. Results: A total of 696 patients with HCC within the Milan criteria involving 801 tumors were included in this study. The complete ablation rate was 93.8% (653/696) and the incidence rate of major complications was 1.7% (12/696). The median survival time was 59.6 months and the 1-, 2-, and 3-year overall survival rates were 94.8%, 82.2%, and 71.7%, respectively. The local recurrence rate was 13.4% (93/696) and the rate of intrahepatic distant metastasis was 40.1% (279/696). The overall intrahepatic recurrence rate was 48.1% (335/696), and the 1-, 2-, and 3-year recurrence rates were 22.9%, 38.4%, and 46.8%, respectively. There were no significant differences in complete ablation rate, incidence rate of major complications, and overall survival rate between the two groups with different tumor sizes (diameters≤3 cm and 3-5 cm) (P = 0.12; P = 0.61; P = 0.61). Conclusion Microwave ablation is a safe and effective treatment modality for HCC within the Milan criteria. And there are no significant differences in safety, effectiveness, and long-term efficacy of microwave ablation between the two groups with different tumor sizes (diameters ≤3 cm and 3-5 cm). However, if the operator’s experience is not rich and cannot accurately use conformal ablation and make an individualized treatment, the tumors with a diameter of 3-5 cm should be carefully treated using microwave ablation to avoid residual tumor after treatment.

Objective: To evaluate the efficacy and safety of drug-coated balloons (DCB) for de novo large coronary vessels. Methods: One hundred and two patients were retrospectively enrolled in this study, there were 104 lesions with the reference lumen diameter of target vessel more than 2.8 mm and patients were treated with DCB in de novo lesions during May 2015 and July 2017 in our center. Coronary artery angiography and quantitative coronary angiography were performed in 82 (80.4%) patients at follow up period ((8.1±1.7) months post procedure). The endpoints were late lumen loss (LLL) at follow up,and major adverse cardiac events (MACE) including cardiac death, myocardial infarction (MI), target lesion revascularization (TLR) and stent or target lesion thrombosis at 12 months post procedure. Results: Ninety-eight lesions were treated with DCB only, 6 (5.9%) bailout drug-eluting stent (DES) were used because of severe coronary dissection, 2 patients (2.0%) received revascularization driven by acute ischemic events during hospitalization. Cutting balloons and NSE balloons were used in 65.4% (68/104) and 26.0% (27/104) lesions. The lesion length was (12.57±3.58) mm and the DCB length was (19.87±4.55) mm. The late lumen loss was (0.01±0.52) mm during angiographic follow up. The TLR rate and overall MACE rate was 3.9% (4/102) and 3.9% (4/102) and there was no death,MI and target lesion thrombosis at 12 months follow up. Conclusion DCB treatment for de novo large coronary vessels is effective and safe.

Objective: To analyze the comparability of different detection systems and methods for tumor markers (TM) by reviewing the results of TM external quality assessment (EQA) in Shandong province during 2015 and 2017. Methods: The results of TM EQA from the Shandong Provincial Clinical Laboratory Center during 2015 and 2017 were collected, and grouped by the detection system or method. After outliers were removed by the CLInet EQA software, the mean and coefficient of variation (CV) in each group were calculated with median as the target value. The difference of TM results in different detection systems were compared by the Kruskal-Wallis H test. Results: Taking alpha-fetoprotein (AFP) as an example, the average CV of different detection methods of TM EQA during 2015 and 2017 ranged from small to large in order of microparticle enzyme immunoassay, electrochemiluminescence, acridine ester chemiluminescence and chemiluminescence. The trends of CV of the other tumor markers were similar to AFP. The average CV of individual marker in electrochemiluminescence group was lower than that in microparticle enzyme immunoassay group. The intra-group CVs of imported detection systems such as Roche, Beckman etc. were relatively ideal, and the average CVs of most tumor markers were less than 10%. However, the intra-group CVs of domestic detection systems such as Shenzhen Snibe, Zhengzhou Autobio etc. were not ideal, and the average CVs of most tumor markers were more than 10%. The target values of different detection systems varied with different items and batches, and there were great variation in carbohydrate antigen (CA) series. Conclusion The results of TM detected by the same automatic detection system are comparable. However, the results of TM detected by most different detection systems and methods are not comparable.
