ObjectiveTo observe the effects of telmisartan on toll-like receptor (TLR) 4 expression in monocytes of mice atherosclerosis (AS)model, and explore the mechanism of inflammation.MethodsAS mice model were established in ApoE-deficient mice fed with high-fat diet,and treated with telmisartan as intervention group. After 8 weeks, serum low density lipoprotein,triacylglycerol and total cholesterol were detected in group fed with high-fat diet and intervention group.TLR 4 expressions in two groups were analyzed by flow cytometry. Results There was no significant difference in levels of blood lipids between the two groups.TLR4 expression in monocytes in telmisartan intervention group was lower than group fed with high-fat diet (P<0.05).ConclusionsTelmisartan may intervene the inflammation during atherosclerosis by downregulating TLR4 expression in monocytes.

Chinese Journal of Integrated Traditional and Western Medicine in Intensive and Critical Care 2018;25(6):586-589
Objective To study the correlation between the polymorphism of CYP2C19 gene and the clinical efficacy of compound Danshen dripping pills in treatment of senile coronary atherosclerotic heart disease (CHD) and to provide theoretical basis for rational drug use. Methods Two hundred and six elderly patients with CHD treated in the Third Hospital of Hebei Medical University from June 2015 to December 2017 were screened for genotype detection and classification. All patients were given oral compound Danshen dripping pills, 10 pills each time, 3 times a day, for consecutive 2 months. Serological indexes, electrocardiograph (ECG) monitoring, liver and kidney function testing were performed before and after treatment to evaluate drug efficacy and adverse reactions. Results In senile patients with CHD, after taking compound danshen dripping pills for 2 months, the efficacy in patients with intermediate metabolizer (IM) was more significantly effective than the efficacies of the patients with extensive metabolizer (EM) and poor metabolizer (PM) [clinical efficacy: 95.6% (87/91) vs. 80.5% (33/41), 93.2% (69/74), ECG efficacy: 95.6% (87/91) vs. 78.0% (32/41), 94.6% (70/74)], at the same time, the serum levels of triglyceride (TG) and high-density lipoprotein (HDL) in patients with IM were also higher than those in patients with PM and EM [TG (mmol/L): 1.33±0.52 vs. 1.33±0.41, 1.33±0.27, HDL (mmol/L): 1.58±1.17 vs. 1.44±0.65, 1.38±0.18], and the levels of total cholesterol (TC), low-density lipoprotein (LDL) and hypersensitive C-reactive protein (hs-CRP) were lower than those of PM and EM [TC (mmol/L): 3.48±0.25 vs. 3.56±0.96, 3.51±0.51, LDL (mmol/L): 2.19±0.35 vs. 2.23±0.49, 2.21±0.87, hs-CRP (mg/L): 3.50±1.07 vs. 3.53±1.51, 3.54±2.01]. The incidences of adverse reactions in patients with EM and IM were significantly lower than the incidence of PM [6.8% (5/74), 9.9% (9/91) vs. 31.7% (13/41)], the differences being statistically significant (both P < 0.05). Conclusions CYP2C19 gene polymorphism is closely related to C HD in elderly, in such patients with IM, after taking compound Danshen dripping pills, the efficacy is significant and has low incidence of adverse reactions. Therefore, in the course of clinical treatment of elderly patients with CHD, genetic testing should be carried out to fully consider the influence of CYP2C19 gene polymorphism on the efficacy of the pill, and adopting personalized therapy can increase efficacy and reduce toxicity.

Objective To research the clinical characteristics of cerebral infarction involving the anterior and posterior circulation in the same time. Methods Collected the clinical data of 11 patients with cerebral infarction involving the anterior and posterior circulation in the same time, who was confirmed by clinical and radiographic examination. Results In the majority of 11 patients, they had multiple risk factors in the same time. By Chinese Ischemic Stroke Subclassification (CISS) criteria, there were 3 patients with large-artery atherosclerotic brain infarction (aortic arch atherosclerosis and intracranial and extracranial large arteries atherosclerosis coexist), 3 patients with cardiogenic stroke, 3 patients with undetermined etiology (intracranial and extracranial large arteries atherosclerosis and cardiogenic stroke maybe coexist), 2 patients with other etiologies(1 patient with Moyamoya disease, 1 patient with polycythemia vera). There were multiple vascular stenosis in the 3 patients with large artery atherosclerosis, and the posterior communicating artery was open. Conclusions Cerebral infarction involving the anterior and posterior circulation in the same time is rare, cardiogenic stroke is more often, the relevant examinations should be perfect to definite the rare cause.

Objective To identify the 2- year recurrence- related factors in patients with myasthenia gravis (MG) after treatment of low-dose tacrolimus. Methods The clinical data of 100 MG patients treated with low- dose tacrolimus from February 2011 to February 2016 were retrospectively analyzed. All patients were followed up at least 2 years, and the risk factors affecting the recurrence of MG patients were analyzed. Results At the end of follow-up, there were 49 cases who had recurrence, and the recurrence rate was 44.5% (49 / 110). Logistic regression analysis result showed that reducing dosage or withdrawal, MG crisis and diabetes mellitus were the independent risk factors for recurrence of MG patients (OR = 134.113, 8.850 and 6.652; P < 0.01 or <0.05). Conclusions The rate of recurrence with low- dose tacrolimus treatment in patients with MG during 2 years is higher. Reducing dosage or withdrawal should be avoided, especially in patients with a history of MG crisis. Patients with diabetics mellitus need to control blood glucose stability to avoid recurrence.
