Objective To investigate the effects of Yindan-Xinnaotong combined with aspirin on lipidemia levels and hemorrheology in patients with stroke. Methods A total of 62 patients with stroke were randomized into a treatment group (31 cases) and a control group (31 cases). The patients in the control group were treated with aspirin and those in the treatment group were treated with aspirin and Yindan-Xinnaotong capsule (4 capsules each time, 3 times/d) for 30 days. The lipidemia levels and hemorrheology were evaluated before and after the treatment. Results After the treatment, whole blood viscosity (4.15 ± 0.14 mPa?s vs. 5.25 ± 0.40 mPa?s;t=14.452, P<0.01), plasma viscosity (1.70 ± 0.30 mPa?s vs. 2.70 ± 0.25 mPa?s;t=14.258, P<0.01), fibrinogen (3.71 ± 0.51 g/L vs. 5.80 ± 0.41 g/L;t=17.783, P<0.01) and thrombosis index (0.75 ± 0.31 vs. 1.30 ± 0.21;t=8.178, P<0.01) in the treatment group were significantly lower than those in the control group. After the treatment, the serum levels of total cholesterol (3.31 ± 1.19 mmol/L vs. 5.04 ± 1.30 mmol/L;t=5.465, P<0.01), triacylglycerol (0.63 ± 0.31 mmol/L vs. 1.34 ± 0.05 mmol/L;t=12.589. P<0.01) in the treatment were significantly lower than those in the control group, the serum level of high-density lipoprotein cholesterol in the treatment group was significantly higher than that in the control group (1.83 ± 0.49 mmol/L vs. 1.28 ± 0.45 mmol/L;t=4.603, P<0.01), and there was no significant difference in the serum level of low-density lipoprotein cholesterol between the two groups (2.22 ± 0.61 mmol/L vs. 2.11 ± 0.95 mmol/L; t=0.543, P>0.05). Conclusion Yindan-Xinnaotong combined with aspirin can improve the lipidemia and hemorrheology in stroke patients.
2.Characteristics and functions of microglia:Advances in studies
Journal of Medical Postgraduates 2017;30(2):216-219
Microglia are functionally principal immune effector cells widely spread in the central nervous system ( CNS) and physiological play a role in monitoring and stabilizing the internal environment. Very sensitive to external stimulation, microglia are eas-ily activated by slight pathological changes in the CNS. The activated microglia, on the one hand, phagocytize cellular debris and ex-crete growth factors to promote nerve repair and, on the other hand, also produce some inflammatory cytokines, glutamate, and nitric oxide, which may aggravate the inflammatory response and lead to secondary injury. This article summarizes the characteristics of mi-croglia and their involvement in CNS diseases and provides a new target for their treatment.

Objective To understand the current situation of neurology nurses′self-efficacy and quality of nursing services in Lanzhou area, and explore the relationship between self-efficacy and the quality of nursing services. Methods Using the method of questionnaire, one hundred and the neurology nurses and hospitalized patients in 5 Grade 3 Level hospitals of Lanzhou city were investigated by using self-efficacy scales and Servqual scales. Results Neurology nurses′ self-efficacy in Lanzhou area was lower than the general population ( U=-9.875,P=0.042);the scores of quality of care from high to low were at reliability, tangibles, assurance, responsiveness, cost acceptability and empathy, which were-(0.12 ± 0.05) points,-(0.23 ± 0.03) points,-(0.24 ± 0.06) points,-(0.25 ± 0.02) points,-(0.26 ± 0.05) points,-(0.66 ± 0.03)points.Satisfaction arranged from high to low were assurance (89.98%), reliability (89.69%), responsiveness (89.12%), tangibles (87.66%), cost acceptability (87.08%), empathy (86.67%).There were positive correlations between satisfaction and expectations and perceived service quality, and the correlation between satisfaction and perceived qualities of service was higher. Moreover, there might exist positive correlation between self-efficacy score and quality of nursing services (reliability, assurance, responsiveness, empathy) (P values were 0.002, 0.001,0.012 and 0.005). Conclusions Neurology nurses in Lanzhou area have lower self-efficacy, and the perceived qualities of care from patients never exceed their expectations. As results, hospital managers should take measures to improve general self-efficacy of nurses, and thus enhance the quality of care.

Objective To analyze the relation between ischemic mitral regurgitation (IMR)and the changes of left ventricular systolic synchrony and volume parameters before and after percutaneous coronary intervention (PCI)in patients with subacute myocardial infarction and to evaluate the impact of PCI on IMR by measuring such changes with three-dimensional echocardiography volume quantitation technology. Methods Eighty-seven patients were enrolled and echo data were acquired before and 6 months after PCI. Patients were classified into alleviation group (group Ⅰ)and non-alleviation group (group Ⅱ)according to the change of mitral regurgitation volume (MRvol).The systolic synchrony indexes (Tmsv 1 6-SD%,Tmsv 1 6-Dif%)and left ventricle volume parameters (LVEDVI and LVESVI)before and after PCI for patients of two groups were measured and contrasted.Results Systolic synchrony indexes of all patients of two groups were improved after PCI.Left ventricular volume parameters were decreased after PCI in group Ⅰ,and the remodeling was reduced.Correlation analysis of the parameters variations showed that,there was significant positive correlation between variations of left ventricular volume and MRvol in all patients and no significant correlation between variation of systolic synchrony index and MRvol.Conclusions PCI can improve left ventricular systolic dyssynchrony for submyocardial infarct patients.Left ventricular volume index that reflects the remodeling process is closely related to IMR.

Objective To investigate the basic perceptions, attitudes and needs towards delirium among ICU professionals in Shandong province, so that to help the ICU supervisors design target training for ICU professionals. Methods A survey was employed utilizing a self-designed questionnaire among 917 ICU professionals(doctors and nurses) from 62 hospitals in Shandong province. Results The score of ICU professionals′ basic perception and behavioral attitude concerning ICU delirium were (24.56 ± 6.36) and (19.00 ± 3.01) points respectively. The score had significant positive correlation and indicates statistic significance (r=0.53, P<0.01). Academic, work experience and title had influence on the score of basic perception (F=14.49, 26.25, 40.16, P<0.05), work experience, category of ICU, title and category of hospital were the effect on the score of behavior and attitude (F=11.87, 8.64, 6.55, P<0.05;t=4.81, P<0.05). The lower rate of correct responding to knowledge of ICU delirium were as follows:the correct rate of delirium in ICU of typing to 56.92%(522/917); the clinical manifestations of ICU delirium accuracy 65.32%(599/917); andrisk factors for delirium in ICU of the correct rate for 70.34%(645/917).ICU professionals acquire knowledge pertaining delirium mainly through lectures, conferences, knowledge brochure , exchange of experience. Conclusions The ICU professionals in Shandong province have less knowledge on ICU delirjum.ICU management should recognize the importance of ICU delirium to strengthen the training of relevant knowledge, enhance delirium management, ensure the patient's safety and improve the prognosis of patients.
