Objective To investigate the risk factors for carotid artery atherosclerosis in young and middle-aged patients with ischemic stroke and the effect of serum lipoprotcin(a) [(Lp (a)] level on young and middle-aged patients with ischemic stroke.Methods Patients with ischemic stroke between the ages of 18 to 55 were enrolled.Carotid artery ultrasonography was used to evaluate the degree of carotid artery atherosclerosis,and the concentrations of serum total cholesterol,triglycerides,high density lipoprotein cholesterol,low density lipoprotein cholesterol,very low density lipoprotein cholesterol,apolipoprotein A1,apolipoprotein B and Lp(a) were detected.According to the results of carotid ultrasound,the patients were divided into groups of without atherosclerosis,plaque without stenosis,and carotid artery stenosis.The demographic and clinical features were compared among the 3 groups.Multivariate logistic regression analysis was used to identify the independent risk factors for carotid artery atherosclerosis in young and middle-aged patients with ischemic stroke.Results A total of 106 patients with ischemic stroke (n =50 in the without atherosclerosis group,n =44 in the plaque without stenosis group,n =12 in the carotid artery stenosis group) were enrolled in the study.The constituent ratios of age (45.98 ±7.12,50.07 ±4.79,and 50.92 ± 1.83 years,respectively; F =7.169,P =0.001),hypertension (26.0％,47.7％ and 58.3％,respectively; x2 =6.862,P =0.032),diabetes mellitus (22.0％,45.5％ and 66.7％,respectively; x2 =10.729,P =0.005),hyperlipidemia (24.0％,40.1％ and 75.0％,respectively; x2=11.372,P=0.003) and smoking (34.0％,61.4％ and 75.0％,respectively;x2 =10.93,P=0.006),as well as the serum high-density lipoprotein cholesterol (1.03 ± 0.26,0.95 ± 0.26 and 0.76 ± 0.08 mmol/L,respectively; F=5.882,P =0.004) and Lp (a) (0.108 ± 0.044,0.155 ± 0.028 and 0.200 ± 0.011 g/L,respectively; F =41.556,P =0.000) levels had significant differences in the 3 groups.Multivariate logistic regression analysis showed that age ＞ 48 years (plaques without stenosis:odds ratio [OR] 2.89,95％ confidenee interval [CI] 1.20-6.96,P =0.018; carotid artery stenosis:OR 4.43,95％ CI 1.19-16.57,P =0.027),hypertension (plaque without stenosis:OR 2.60,95 ％ CI 1.09-6.18,P =0.031; carotid artery stenosis:OR 3.99,95％ CI 1.08-14.77,P =0.039),diabetes (plaque without stenosis:OR 2.96,95％ CI 1.21-7.23,P=0.018; carotid artery stenosis:OR 7.09,95％ CI 1.79-28.02,P =0.005),hyperlipidemia (plaque without stenosis:OR 2.19,95％ CI 0.91-5.31,P =0.082; carotid artery stenosis:OR 9.50,95％ CI 2.21-40.86,P =0.002),smoking (plaque without stenosis:OR 3.08,95％ CI 1.33-7.16,P =0.009; carotid artery stenosis:OR 5.82,95％ CI 1.39-24.38,P =0.016),and Lp (a) (plaque without stenosis:OR 4.38,95％ CI 1.76-10.90,P=0.001; carotid artery stenosis:OR 12.80,95％ CI 2.73-52.67,P =0.001) were the independent risk factors for carotid artery atherosclerosis in young and middle-aged patients with ischemic stroke.Conclusions Age,smoking hypertension,diabetes and Lp(a) were the independent risk factors for carotid artery atherosclerosis in young and middle-aged patients with ischemic stroke.

[Objective] To observe Yishi Oral Liquid effect on treating middle and old aged asthenopia. [Method] Choose 125 cases of middle and old aged asthenopia, and randomly divide them into observation group 65 cases treated wutg Yishi Oral Liquid, and control group 60 cases with Mingmu Rehmannia Pil;meanwhile both groups reduced the time with the eye and made massage on the acupoints around the eyes. [Result] With 2~4 weeks of treatment, in the observation group, 23 cases were cured, 25 had marked effect, 13 effective, 11 had no effect, the total effective rate was 93.85%;for the control one, they were respectively 14,19,16,11 and 81.67%. The comparison showed the observation group was better than control one. [Conclusion] Yishi Oral Liquid treating middle and old aged asthenopia has good clinical effect, can obviously relieve the symptoms of blurred vision, phengophobia, lacrimation and aningerestling eyes, helpful to recovering eyesight.

Objective:To study the clinical efficacy of loratadine combined with pidotimod in the treatment of children with repeat-ed respiratory tract infection and the effect of the combination on immune function. Methods:Totally 78 cases of patients with repeated respiratory tract infection were randomly divided into the observation group ( n=39 ) and the control group ( n =39 ) . Both of the groups were treated with the routine correct treatment, and the control group was treated with pidotimod and the observation group was treated with loratadine combined with pidotimod with the treatment course of 8 weeks. The clinical efficacy, clinical symptoms, signs improvements, changes of immune function markers level and incidence of adverse drug reactions between the two groups were observed and compared. Results:The total effective rate of the observation group was significantly higher than that of the control group ( P<0. 05);the disappearance time of pulmonary rales and cough, fading time of tonsil swelling and fever clearing time of the observation group were significantly shorter than those of the control group(P<0. 05). After the treatment, the levels of IgG, IgM and IgA in both groups were significantly lower than those before the treatment (P <0.05); the levels of CD3 +, CD4 + and CD4 + /CD8 + in both groups were significantly higher than those before the treatment (P<0. 05);the levels of immune indices in the observation group were significantly better than those in the control group(P<0. 05). Comparing with the incidence of adverse drug reactions in the control group, no significant difference was shown in the observation group (P>0. 05). Conclusion:The clinical efficacy of loratadine com-bined with pidotimod in the treatment of children with repeated respiratory tract infection is effective, which can improve the clinical symptom and signs and enhance the immune function of children significantly.

Effective leadership is crucial for health organizations' performance and numerous western universities thus offer leadership courses or modules to their students.However,such education practice has not started in China.In order to optimize knowledge and skills of health service management practitioners,to content with requirements of health service organizations,to cope with dynamic organization environment,to implement health reform successfully and to realized sustainable development of health organizations,it is necessary to provide leadership course for students of health service management at Chinese universities.
