    Venous thromboembolism (VTE) is constituted by pulmonary thromboembolism (PTE) and deep venous thrombosis (DVT). Blood hypercoagulable, along with vascular damage and stasis during pregnancy and puerperium contribute to a high incidence of VTE. In clinically suspected VTE, anticoagulation therapy should be commenced immediately until the diagnosis is excluded by objective testing, unless treatment is strongly contraindicated. Low molecular weight heparin (LMWH) does not pass through the placenta and is safe in breastfeeding, hence will be the best choice for pregnancy and puerperium. Treatment with LMWH should be employed during the remainder of the pregnancy and last for at least 6 weeks postnatally and at least 3 months of treatment will be necessary.

    Objective To explore early diagnosis and prognosis evaluation in acute cerebral infarction (onset < 24 h) using the heart acid binding protein (H-FABP) accompanied with neuron-specific enolase (NSE).Methods 109 patients with acute cerebral infarction (ACI group) were selected as experimental group. Then, the patients were divided into three subgroups(light, medium, heavy) according to the defect degree of nerve function. 80 patients with transient ischemic attack (TIA group) were selected as control group. H-FABP and NSE in serum, NIHSS score and volume of nidus were tested before and after treatment. The difference of H-FABP and NSE in serum before and after treatment were compared, and the relationships between H-FABP, NSE and NIHSS score and volume of nidus were explored.Results ①The serum H-FABP and NSE of ACI group were obviously higher than normal values(P<0.01). ②The H-FABP of ACI group was higher than that of TIA group (P<0.01). ③The serum H-FABP of the three subgroups from ACI group rose as the disease aggravated (P<0.01). ④The serum H-FABP of ACI group was positive related to NIHSS score and infarct volume(rs=0.338,0.246,P<0.01). The serum NSE was positive related to infarct volume (rs=0.203,P<0.05). The infarct volume was positive related to NIHSS score (rs=0.265,P<0.01). ⑤The serum H-FABP and NSE of ACI group decreased after treatment as comparing with before treatment(P<0.05,P<0.01). The different values of serum H-FABP and NSE were positive related to different values of NIHSS score before and after treatment (rs=0.665,0.512,P<0.01).Conclusion The serum H-FABP and NSE would rise abnormally in ACI patients and were positively related to nerve damage and the degree of prognosis. Both indexes can be used as sensitive indicators for disease outcome and prognosis evaluation.

    Objective To investigate the relationship between proprotein convertase subtilisin/kexin type 9 (PCSK9) and inflammatory factor expression in apoptosis of human umbilical vein endothelial cells (HUVECs) induced by oxidized low density lipoprotein(ox-LDL).Methods HUVECs were incubated with ox-LDL for different times (0 h,12 h,24 h,36 h,48 h). The mRNA and protein expression of PCSK9, inter leukin 6(IL-6), monocyte chemotactic protein-1(MCP-1), matrix metalloprotein-9(MMP-9), C-reactive protein (CRP) and the nucler displacement of nucler factor-kappa B (NF-κB) were detected. The siRNA for PCSK9 was designed and synthesized,then was transfected into HUVECs by Lipofectamine 2000. After transfection for 6 h, cells were treated with ox-LDL for 24 h, the mRNA and protein expression of PCSK9, IL-6, MCP-1, MMP-9, CRP and the nucler displacement of NF-κB were detected.Results With the increase of ox-LDL processing time, the mRNA expressions of PCSK9, IL-6, MCP-1, MMP-9 and CRP were significantly higher, and the nucler displacement of NF-κB was significantly increased, especially for 24 h incubation, and the subsequent expression and the nucler displacement were gradually decreased (P<0.05). The protein concentration of IL-6, MCP-1, CRP and MMP-9 in cell culture supernatant increased gradually over time, and reached the peak at 48 h. Compared with the 0 h group, the 48 h group increased most obviously (P<0.01). The mRNA and protein expressions of PCSK9, IL-6, MCP-1, MMP-9, CRP and the nucler displacement of NF-κB in siRNA group were significantly lower than those in negative transfection group (P<0.01).Conclusion PCSK9 siRNA can inhibit inflammation factor expression in apoptosis of HUVECs induced by ox-LDL. And PCSK9 may be involved in the regulation of inflammation.

    Objective To observe the efficacy and safety of ticagrelor treated on patients with low clopidogrel response.Methods A total of 173 of 493 patients undergoing percutaneous coronary intervention(PCI)with acute coronary syndrome(ACS) were selected as low colpidogrel response identified by thrombelastography and enrolled in this study. Patients with low clopidogrel response were randomized into clopidogrel treated group(n=87) and ticagrelor treated group(n=86). Patients responding to clopidogrel were still treated with clopidogrel(75 mg daily)and patients with low clopidogrel response received ticagrelor treatment(90 mg twice daily). Platelet aggregation rate was compared between two groups after treatment for 3 days, 7 days and 30 days. All patients were followed 12 months for major adverse cardiovascular events(MACCE) and bleeding events.Results Patients in ticagrelor treated group showed significantly lower platelet aggregation rate compared with patients in clopidogrel treated group after 3 days, 7 days, and 30 days (P<0.05). Patients in ticagrelor treated group showed significantly lower MACCE rate compared with patients in clopidogrel treated group in the postoperative 12 months' follow-up(P<0.05). There were no significant difference in bleeding events(P>0.05).Conclusion Ticagrelor therapy can achieve ideal antiplatelet effects for patients with low clopidogrel response. For the patients with low clopidogrel response receiving PCI, ticagrelor can be an effecive and safe choice for antiplatelet therary.

    Objective To qualitatively evaluate the right ventricular function and the pulmonary artery obstruction degree in patients of acute pulmonary embolism (APE) with computed tomographic pulmonary angiography (CTPA).Methods Retrospective assessment was made in 75 APE patients, mean age (59.2±13.3) years; range 25-80 years; 33 women. CT pulmonary angiography examinations were performed in the patients. CT pulmonary artery obstruction scores (OS) were used in the assessment of pulmonary arterial obstruction severity. All patients were divided into mild (n=18), moderate (n=25), or severe groups (n=32) according to OS <30%, 30%-50%, ≥50% respectively. Right ventricular function was assessed on CT in all patients by measuring right ventricular short axis diameter(RVd), left ventricular short axis diameter (LVd), RVd to LVd(RVd/LVd) ratio, main pulmonary artery, azygos vein, superior vena cava diameters. Also, these CT parameters for right ventricular function were compared among three groups.Results The correlation between CT pulmonary artery OS and cardiovascular parameters was significant (P<0.01). The cardiovascular parameters including RVd, RVd/LVd ratio, main pulmonary artery diameter, azygos vein diameter, superior vena cava diameter in patients with moderate and severe APE (OS 30%-50% and OS≥50%, respectively) were higher than those with mild APE (OS<30%) (P<0.05). And LVd in patients with moderate and severe APE was lower than that with mild APE (P<0.05). In the meantime, comparison of cardiovascular parameters between patients with moderate and severe APE showed significant differences (P<0.05).Conclusion Quantitative CT parameters prove useful in evaluating the right ventricular function and the pulmonary artery obstruction degree in APE, and there was significant correlation between the right ventricular function and the pulmonary artery obstruction degree.

    Objective To explore the diagnosis value of α-L-fucosidase (AFU),5'-nucleo tidase (5’-NT) and alpha fetoprotein (AFP) detection in patients with primary hepatic carcinoma(PHC).Methods The study involved 40 patients with hepatocellular carcinoma as experimental group and 60 cases of physical examination as control group, using ROC curve to make a comparative analysis. The patients with hepatocellular carcinoma who experienced surgical treatment were followed up for average six months.The patients were divided into relapse group and non-recurrent group, to AFU, 5 - NT, AFP levels were detected to assess the predictive value.Results The level of AFU,5’-NT and AFP in PHC group were higher than those in control group (P<0.05).The area under the ROC curve for the three indexes were 0.904, 0.870 and 0.866,respectively. The concentrations of AFU in preoperative and postoperative detection were significantly higher than those of non-recurrent group. However, 5 - NT concentration showed no statistic difference between preoperative and postoperative concentration detection. Preoperative concentration of AFP was no significantly higher than that of non-recurrent group, but preoperation concentration of AFP was significantly higher than that of non recurrent group.Conclusion ROC curve suggests that the combined detection of AFU and 5' –NT is superior to any single index in PHC diagnosis.It can greatly increase the detection of PHC. AFU could be used as early recurrence indicator of PHC.
