Dyslipidemia refers to the elevated cholesterol,triacylglyceride levels and/or the reduced high density lipoprotein level.It is the important risk factor for the occurrence of atherosclerosis,and it is alsoassociated with the onset and outcome of acute cerebrovascular disease.Therefore,the highly efficient and comprehensive lipid lowering therapy has become one of the most important and effective prevention measures for cerebrovascular disease.This article reviews the recent advances in research on dyslipidemia and lipid lowering therapy in patients with cerebrovascular disease.

Objective To observe clinical application of the apparent Shikani laryngoscope in difficult airway, so as to provide reference for basic-level hospitals to deal with difficult airway. Methods 50 patients with difficult airway were randomly divided into 2 groups:Shikani laryngoscope group (S) that direct laryngoscope group (M) . After conventional induction, patients in two groups were given endotracheal intubation with different intubation tools by the same anesthesiologist, then the intubation time and the one-time success rate of intubation were compared between two groups. The hemodynamics of patients, were observed in two groups,the HR,SBP,DBP and SPO2 at before (T0),during (T1),2 min after (T2) and 5 min after intubation (T3) were recorded. The complications including gingival and oral mucosa bleeding, sore throat, hoarseness were also recorded in two groups.Results During the process of intubation, the hemodynamic changes of patients had statistically significant difference between T0 and T1, T2,T3 subgroups ( <0.05),T2 and T3 subgroups ( <0.05) . The intubation had less influence on hemodynamics of patients in group S than M group,but the SPO2 and T0 had no significant difference between two groups ( >0.05) .Comared with M group,the one-time success rate of intubation was higher,and the intubation time was shorter in S group and there were significant differences ( <0.05) . There was no significant difference in the intubation complications between the two groups ( > 0.05), and this may be associated with small sample cases. Conclusion Compared with ordinary laryngoscope, Shikani laryngoscope has incomparable advantages in handling difficult airway and is convenient to apply,so it is worth popularizing in basic-level hospitals.

AIM: To evaluate the effect of simvastatin on the left ventricular mass in patients with essential hypertension (EH). METHODS: 50 patients with hypertension without severe complication were randomly divided into two treatment groups: combination treatment group and hydragogue group, and 25 normal subjects without any treatment were taken as the control. The 25 patients in combination treatment group were given simvastatin and hydragogue for 12 weeks while the other patients in hydragogue group were given hydragogue during the same time. The left ventricular mass was examined from ultrasonography in all patients before and after treatment. RESULTS: The left ventricular mass index (LVMI) was higher in the two treatment groups of patients (133.61±31.02, 118.04±39.62 g·m-2) than that in the control group (88.79±22.73 g·m-2) before treatment (P<0.01, 0.0001, respectively) while the blood pressure was higher. There was no significantly difference in age, serum concentrations of total cholesterol or triglyceride, sugar and blood pressure between the two treatment groups and the control group (P>0.05). There was no significant difference in all variables between the two treatment groups before treatment. After treatment, the LVMI was decreased (133.61±31.02 vs 91.07±16.01 g·m-2, P<0.01) in the combination treatment group while there was no significant change in LVMI in the hydragogue group compared with the control group. The blood pressure in the two treatment groups was decreased to the normal. Compared with hydragogue group, the change of LVMI was higher in the combination group though the serum concentrations of total cholesterol, triglyceride or sugar were not significantly different. No significant change in serum concentrations of total cholesterol, triglyceride or sugar was found during treatment in the two groups. The change of LVMI did not correlate with the change of blood pressure, serum concentrations of total cholesterol , triglyceride or sugar in the combination treatment group(P>0.05). CONCLUSION: Being independent of the changes of serum concentrations of total cholesterol, triglyceride or sugar and blood pressure, simvastatin can inhibit the increase of left ventricular mass in patients with essential hypertension.

This study is to develop a therapeutic drug monitoring (TDM) network server of tacrolimus for Chinese renal transplant patients, which can facilitate doctor to manage patients' information and provide three levels of predictions. Database management system MySQL was employed to build and manage the database of patients and doctors' information, and hypertext mark-up language (HTML) and Java server pages (JSP) technology were employed to construct network server for database management. Based on the population pharmacokinetic model of tacrolimus for Chinese renal transplant patients, above program languages were used to construct the population prediction and subpopulation prediction modules. Based on Bayesian principle and maximization of the posterior probability function, an objective function was established, and minimized by an optimization algorithm to estimate patient's individual pharmacokinetic parameters. It is proved that the network server has the basic functions for database management and three levels of prediction to aid doctor to optimize the regimen of tacrolimus for Chinese renal transplant patients.

ObjectiveTo assess myocardial perfusion by the end-systolic and end-diastolic replenishment parameters of real-time myocardial contrast echocardiography (MCE).MethodsTwenty-one patients with myocardial infarction(MI) and normal control group of 6 cases underwent intravenous realtime myocardial contrast echocardiography via slow and homogeneous venous injections of SonoVue.MCE images were obtained from the apical 4-chamber,2-chamber,and long-axis views.According to the exponential function:y(t) =A [1 - e-kt] + B,the time intensity curves were obtained.By an off-line ECG triggering and curve fitting,the replenishment parameters A value,k value,A × k value were obtained separately from end-systolic and end-diastolic images.ResultsIn normal control group,the end-systolic replenishment parameters A value,k value,A × k value were all lower than that of the end-diastolic replenishment parameters[(6.21 ± 2.69)dB vs (7.93 ± 3.66)dB,P ＜0.05；0.36 ± 0.15 vs 0.42 ± 0.19,P ＜ 0.01 ;2.88 ± 1.29 vs 3.39 ± 1.61,P ＜0.05,respectively].The end-diastolic replenishment parameters were found significantly greater variability than the end-systolic values (variation coefficient CV:A value 46.2％ vs 43.3％,k value 45.2％ vs 41.4％,A× k value 47.5％ vs 44.8％,all P ＜0.05).In 21 patients,the end-systolic replenishment parameters in myocardial segments supplied by infarct-related coronary artery were significantly lower than that in myocardial segments supplied by non - infarct - related coronary artery.ConclusionsThe end-systolic and end-diastolic replenishment parameters of real time myocardial contrast echocardiography can assess myocardial perfusion.The variability of the end-systolic replenishment parameters is smaller than that of the end diastolic parameters.Significant variability in k-value suggests that this parameter is best suited for before-after study in the same patient.

Objective To study the correlation between isokinetic parameters and modified Ashworth Scale (MAS) in ankle spasticity as-sessment. Methods 18 stroke patients (spasticity group) and 16 healthy subjects (control group) in our hospitals from August 2014 to March 2015 were included. MAS was used to assess the ankle muscular tension. The ankle passive movement of both groups was measured with BIODEX isokinetic motor assessment system under 10 °/s, 60 °/s, 120 °/s, 180 °/s, 240 °/s. The peak torque (PT), peak torque/body weight (PT/BW), average torque (AT), and slopes of the linear regression curve of torque-velocity (SLOPE) were recorded. The correlation of the isokinetic paramenters and the MAS were tested with Spearman correlation analysis. Results The PT, PT/BW and AT were higher in the spasticity group than in the control group (P<0.05). And they increased as the angular velocity increased, and slowed after 120 °/s. The corre-lation coefficient of MAS and PT, PT/BW, AT, SLOPE were from 0.3043 to 0.7632 (P<0.01). Conclusion The isokinetic parameters were speed-dependent and closely related to MAS. 120 °/s was of the highest sensitivity, and the SLOPE under this anglular velocity was highly correlated with MAS.
