Clinical effect of Maixuekang Capsule (脉血康胶囊) on long-term prognosis in patients with acute coronary syndrome after percutaneous coronary intervention / 中国结合医学杂志

<p><b>OBJECTIVE</b>To study the changes of adenosine diphosphate (ADP)-induced platelet aggregation rate, and evaluate the effects of Maixuekang Capsule (, MKC) on platelet aggregation rate and long-term prognosis of patients with acute coronary syndrome after percutaneous coronary intervention (PCI).</p><p><b>METHODS</b>A total of 236 patients with acute coronary syndrome, who received successful PCI, were randomly assigned to a trial group (116 cases) and a control group (120 cases) according to random numbers; treatment allocation occurred when the participants met the inclusion criteria and signed the informed consent forms. In the trial group, the patients were treated with MKC combined with routine medication, and in the control group the patients were treated with routine medication. The therapeutic course for the two groups was 12 months and the follow-up was 12 months. The levels of ADP-induced platelet aggregation rate and serum high-sensitive C-reactive protein (hs-CRP) were determined before PCI, 12 h and 30 days after PCI. In the meantime, the incidence of cardio-/cerebrovascular events was recorded during the 12-month follow-up.</p><p><b>RESULTS</b>Compared with before PCI, the levels of ADP-induced platelet aggregation rate and serum hs-CRP were significantly higher at 12 h after PCI (P<0.05). They were significantly reduced after 30-day-treatment of MKC, showing statistical differences when compared with those in the control group (P<0.05). During the 12-month follow-up, the incidence of cardio-/cerebrovascular events was significantly lower in the trial group than in the control group (6.9% vs. 12.5%, P<0.01).</p><p><b>CONCLUSIONS</b>ADP-induced platelet aggregation function was significantly elevated after PCI. MKC improved the prognosis of patients with acute coronary syndrome, possibly through inhibiting the platelet aggregation, fighting against inflammation, and protecting the vascular endothelial function.</p>

Clinical characteristics and prognosis analysis of patients with LMP-1 positive Hodgkin's lymphoma after EBV infection / 中国实验血液学杂志

This study was purposed to investigate the expression of latent membrane protein 1 (LMP-1) and CD68 in Hodgkin's lymphoma (HL) patients with EB virus infection and to analyze the relation of LMP-1 expression and CD68(+) tumor-associated macrophage count with clinical features and prognosis of HL patients. The expression of LMP1 and count of CD68(+) TAM were detected by immunohistochemical staining in tissue specimens of 72 HL patients; their correlation with clinical features and prognosis of HL patients was analyzed by using statistical method. The results showed that among tissue specimens of 72 HL patients, the positive rate of LMP-1 expression was 18.1% (13/72), the CD68(+) TAM count was more higher in LMP-1 positive expression [250 of CD68(+) TAM/high power field (hpf) is used as demarcation point] (P = 0.003). The statistical analysis showed that the LMP-1 positive expression was more observed in mixed type HL patients (P = 0.000); the positive rate of LMP-1 expression was much high in HL patients with albumin <40 g/L and age ≥ 45 years (P < 0.05). There was no relation of LMP-1 expression and CD68(+) TAM count with the short term therapeutic efficacy of HL patients, but the overall survival time of LMP-1 positive patients among patients followed-up for ≥ 5 years was short (P < 0.05). Moveover, no correlation of CD68(+) TAM count with the overall survival time of HL patients was found. It is concluded that the high count of CD68(+) TAM is more observed in LMP-1 positive expression of HL tissue, the LMP-1 expression states relates both with the pathological types, age and albumin level of patient with HL. The HL patients with LMP-1 positive expression have poor prognosis, suggesting that LMP-1 may be a new prognostic marker for HL patients.

Combined effect of atorvastatin and probucol on plasma cystatin C levels and severity of coronary lesion in patients with borderline coronary lesion / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The plasma cystatin C concentration (PcyC) has been demonstrated to have prognostic value in acute coronary syndrome, but the study of PcyC in patients with borderline coronary lesions is limited. Moreover, the effects of atorvastatin and probucol on PcyC and the severity of coronary lesions are unknown. This study was to evaluate the effects of the combination of atorvastatin and probucol on PcyC and severity of coronary lesion in patients with borderline coronary lesions.</p><p><b>METHODS</b>One hundred and thirty consecutive patients with borderline coronary lesions (40% to 60% isolated single stenosis assessed by quantitative coronary angiography) were enrolled into the borderline coronary lesion (BCL) group, and one hundred and thirty-six subjects without coronary lesions comprised the controls (CTR). The subjects in the BCL group were randomized into routine treatment (RTT, n = 60), and combined treatment with atorvastatin 20 mg plus probucol 1.0 g daily added to routine medication (CBT, n = 70), both groups were treated for 6 months continuously. The levels of PcyC, high-sensitive C-reactive protein (hs-CRP), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG) were determined. One hundred and four subjects in the BCL group were rechecked by coronary angiography.</p><p><b>RESULTS</b>PcyC levels were significantly higher in the BCL group than in the CTR group; (2003.26 ± 825.73) ng/ml vs. (1897.83 ± 664.46) ng/ml (P < 0.01). Compared with patients in the RTT group, the levels of PcyC, TC, LDL-C, TG and hs-CRP were significantly lower in the CBT group (P < 0.05). Moreover, there was a trend towards a slight decrease in the RTT patients, (54.38 ± 10.67)% vs. (50.29 ± 9.89)% (P > 0.05), and a significant decrease in the CBT patients, (53.65 ± 9.48%) vs. (40.38 ± 12.93)% (P < 0.05), in the mean percent stenosis of borderline coronary lesions before and after six months of treatment.</p><p><b>CONCLUSIONS</b>Cystatin C played an important role in the development of coronary artery disease, and was associated with the severity of coronary lesions. The combination of atorvastatin and probucol decreased PcyC levels, and could be the treatment of choice.</p>
