Objective To investigate the adjustment and value of lymphocyte G protein-coupled receptor kinase-2 (GRK2) protein levels in patients with acute coronary syndrome(ACS). Methods Forty-two patients with stable angina pectoris (SAP), 44 patients with unstable angina pectoris (UAP), 43 patients with acute myocardial infarction (AMI), and 46 patients with normal coronary angiography (NCA) in hospital were enrolled in this study. Lymphocyte GRK2 protein levels were analyzed by Western blot in 24 h after admitted to hospital. Heart rate variability (HRV) analysis was performed based on 24 h Holter electrocardiogram (ECG) monitoring. Cardiac functions were measured using ultrasonic cardiogram. The results were compared and the relationship between GRK2 protein levels and HRV, cardiac functions index was analyzed. Results The level of lymphocyte GRK2 in AMI group, UAP group, SAP group and NCA group was (209.8 ± 63.9)%, (165.6 ± 60.2)%, (131.7 ± 51.8)% and (125.3 ± 50.6)%. The levels of lymphocyte GRK2 in AMI group and UAP group was significantly higher than that in SAP group and NCA group .Moreover, the level of GRK2 was the highest in AMI group, and there were significant differences (P<0.01). The level of lymphocyte GRK2 had negative correlation with high frequency(HF), low frequency(LF), LF/HF, standard deviation NN interval (SDNN), standard deviation of the average normal RR interval for 5-minute segments (SDNNI) and left ventricular ejection fraction (LVEF) (r =-0.52,-0.47,-0.53,-0.56,-0.49,-0.51, P < 0.01). Conclusions The rise of lymphocyte GRK2 protein levels is significantly associated with increased sympathetic nerve excitability and deterioration of cardiac function.

The study is to prepare taste masking and enteric-coated clarithromycin granules by melting and fluid bed coating technology. Clarithromycin and matrix materials were melted at a certain temperature, and then made into particles by fluidized bed coating. X-ray powder diffraction and scanning electron microscopy were used to identify the crystal and morphology of drug loading granules. In vitro dissolution method was used for the observation of the drug release behavior. The results showed that the drug particles size range was 0.2 - 0.6 mm; the crystal form of clarithromycin in the granule did not change; enteric-coated granules accumulated release in 0.1 mol L(-1) hydrochloric acid in 2 h was less than 10%, while in pH 6.8 phosphate buffer in 1 h was more than 80%. The taste masking and enteric-coated clarithromycin granules not only have good taste masking effect, but also have a good release behavior. It is expected to have better clinical application.

This article was aimed to study the Uygur medicine Hyssopus officinalis L. on the balance of Th1/Th2 and Th17/Treg of chronic obstructive pulmonary disease (COPD) mice in order to explore the mechanism of its treatment of COPD. The pre-fumigation method was copied to establish a mouse model of COPD. Mice were ran-domly divided into the normal control group, saline group and water extract of H. officinalis L. high, middle and low dose group. The level of serum IFN-λ, IL-4, IL-17 and IL-10 were detected with ELISA. The results showed that compared with the normal control group, the serum IL-4 and IL-17 level of the COPD model group were significantly higher (P < 0.05), and the serum IFN-λ and IL-10 level were significantly lower (P < 0.05). After drug intervention, the IL-4 and IL-17 level were significantly lower, and the IFN-λ and IL-10 level were significantly increased compared with the model group. The correlation analysis showed that the IFN-λ, IL-4, IL-17 and IL-10 were negatively related. It was concluded that H. officinalis L. played a certain role on correct-ing imbalances of Th1/Th2 and Th17/Treg.
