OBJECTIVE:To provide reference for strengthening the safety of the combination use of CYP3A4 inhibitors with statins in clinical treatment. METHODS:30 cases per month(totally 300 cases)(the hospitalization time was more than 10 days) discharged from the cardiology department of a third-level class A hospital during Jan. to Oct. 2013 were selected randomly,and statistical analysis was made into general information of patients,whether to use statins and CYP3A4 inhibitor,and whether to monitor safety indicators of liver and kidney function and creatine kinase. RESULTS:Totally 291 patients were treated with statins with a total use rate of 97%,including 265 cases of atorvastatin and 11 cases of simvastatin. The CYP3A4 inhibitors were com-bined with amlodipine,diltiazem,verapammy,amiodarone,Ginkgo biloba leaf,fenofibrate and clarithromycin,etc.,and 162 (59%) patients were given the combination use of simvastatin or atorvastatin with CYP3A4 inhibitors. But the liver and kidney function,creatine kinase and other safety indicators were not monitored by laboratory examination during medication. CONCLU-SIONS:Atorvastatin and simvastatin are used commonly in patients with cardiovascular disease,and the combination use rate with CYP3A4 inhibitor is relatively higher and needs long-term medication,drug dosage should be limited according to the direction of instructions and the adverse reactions induced by drug interactions should be noticed to strengthen medication monitor and education for patients.

Chitosan has natural abundance, unique bioactivity and attractive physicochemical properties. Recent years, the synthesis of chitosan-based metal nanomaterials has attracted increasing attention. The synthesis of metal nanoparticles utilizing biomolecular or organism offers a mild medium, and thus a greater degree of control over the nanoparticles produced, along with higher reproducibility. In particular, preparation of metal nanoparticles based on biomolecular or organism has its unique facility in integrating "minimum feature sizes" into labile biological components to an excellent synergy and bifunctional effect and consequently a more broad application. Herein, we review the new development of chitosan, chitosan-based synthesis of metal nanomaterials, and their application.

The Batthel index of the rehabilitation group was (72.25±10.22), the index of the control group was (22.62±9.71),which was significantly different from that of the rehabilitation group, P < 0.05.Besidcs, the rate of knowing health knowledge and healthy exercise in the rehabilitation group was higher than that of the control group, P < 0.05. Condusions The rehabilitation information net and systemic community rehabilitation intervention can im-prove the motor ability and the ability of daily activity for patients with stroke.

OBJECTIVETo investigate the characteristics for activated coagulation factor VII(F VIIa) and the R353Q, -323 0/10 bp, HVR4 polymorphisms in the gene in patients with coronary heart disease (CHD) and myocardial infarction from Ningxia Hui and Han populations.

METHODSFour hundred and twenty angiographically proven CHD patients in the Hui population, and 508 healthy blood donors were tested for their plasma levels of coagulation factor VII using recombinant tissue factor method. The coagulation factor VII gene R353Q, -323 0/10 bp and HVR4 genotypes were identified by polymerase chain reaction. In addition, 600 Han patients with CHD and 604 healthy Han control subjects were also investigated.

RESULTS(1) The plasma F VIIa levels was significantly higher in patients with CHD and myocardial infarction than that in healthy control subjects and angor pectoris (P<0.01) in both Hui and Han populations. (2) There were significant differences in the distribution of genotypes and allelic frequencies of the R353Q between myocardial infarction and angor pectoris disease in the Hui population (P<0.05). So was the -323 0/10 bp locus in both the Hui and Han population. (3) The F VIIa level was significantly higher in individuals with RR genotype than those of Q allele carriers in the Hui population.

CONCLUSIONThere are polymorphisms of the F VII gene R353Q, -323 0/10 bp and HVR4 in the Hui and Han populations. The Q allele might be a protective factor against myocardial infarction in the Hui, and the plasma F VIIa level may be influenced by the R353Q polymorphism of the F VII gene. The 10 allele may be a protective factor against myocardial infarction in both the Hui and Han populations.

Objective: To explore the effects of change of activity of vacuolar adenosine triphosphatase (V-ATPase) of myocardial lysosome on myocardial damage in rats after severe burn and its mechanism. Methods: The myocardial lysosomes were extracted from the hearts of 12 SD rats with ultra-high speed gradient density centrifugation, then Western blotting and transmission electron microscope observation were conducted for identification. One hundred and twenty rats were divided into pure burn group, ATP group, normal control group, and bafilomycin group according to the random number table, with 30 rats in each group. Rats in pure burn group and ATP group were inflicted with 40% TBSA full-thickness scald on the back. Immediately after injury, rats in pure burn group were intraperitoneally injected with lactated Ringer′s solution in 4 mL·%TBSA^-1·kg^-1, and rats in ATP group were intraperitoneally injected with ATP in 0.4 mg/kg at 12 h before burn, immediately after burn, and 12 h after burn. Rats in normal control group did not receive any treatment, and rats in bafilomycin group were intraperitoneally injected with bafilomycin A1 in 0.3 mg/kg at the same time points as those of ATP group. At 24 h after burn, 30 rats from each group were collected for determining activity of V-ATPase of myocardial lysosome with coupled-enzyme assay and the expression of myocardium autophagy-related proteins microtubule-associated protein 1 light chain 3 (LC3) and P62 by Western blotting. Left ventricular arterial blood was collected to detect the content of 5 items of myocardial enzyme spectrum and cardiac troponin T (cTnT). Data were processed with one-way analysis of variance and t test. Results: (1) After identification, both the expression level of lysosome-related membrane protein 1 and purity of lysosome in the sample were high, and the structure of lysosome was intact. (2) At 24 h after burn, the activity values of V-ATPase of myocardial lysosome in rats of pure burn group, ATP group, normal control group, and bafilomycin group were (2.03±0.67), (3.01±0.58), (4.29±0.26), and (1.83±0.52) μmol·mg^-1·h^-1, respectively. The activity value of V-ATPase of myocardial lysosome in rats of pure burn group was significantly lower than the values in ATP group and normal control group (with t values respectively 3.14 and 8.87, P values below 0.01). The activity values of V-ATPase of rats in normal control group were significantly higher than those in bafilomycin group (t=11.87, P<0.01). At 24 h after burn, the expressions of myocardial LC3 and P62 in pure burn group were significantly higher than those in ATP group and normal control group (with t values from 3.73 to 5.88, P values below 0.01). The expressions of myocardial LC3 and P62 in normal control group were significantly lower than those in bafilomycin group (with t values respectively 2.64 and 3.07, P<0.05 or P<0.01). At 24 h after burn, the content of 5 items of myocardial enzyme spectrum and cTnT in pure burn group was significantly higher than that in ATP group and normal control group (with t values from 3.24 to 16.72, P values below 0.01). The content of 5 items of myocardial enzyme spectrum and cTnT in normal control group was significantly lower than that in bafilomycin group (with t values from 2.39 to 10. 70, P values below 0.01). Conclusions The activity of V-ATPase of myocardial lysosome decreased in rats after severe burn, which can result in myocardial damage by inhibiting myocardial autophagy flux.

Objective To explore the specific plasma exosomal protein expression in Coronary Heart Disease(CHD)with phlegm-turbidity syndrome(PTS),so as to provide biological reference for the diagnosis of CHD with PTS.Methods A total of 20 CHD patients with PTS and 20 healthy subjects at the same period were included.Plasma exosomes were extracted from all subjects using the qEV size exclusion method.First,10 CHD cases with PTS and 10 healthy subjects were randomly selected,and differentially expressed proteins between the two groups were screened using label free non-targeted protein quantification analysis.Then,MRM targeting protein labeling technique was applied to verify the differentially expressed proteins in the remaining subjects.Results Compared with healthy controls,214 differentially expressed plasma exosomal proteins(61 up-regulated and 153 down-regulated)were found in CHD patients with PTS,mainly related to cholesterol metabolism,complement and coagulation cascade,and immune effects.ANXA6,C4BPB,F8,CFB,APOE,C9,and CLU proteins were further validated by MRM targeting protein.Conclusion CHD patients with PTS had differences in plasma exosomal protein expression from healthy controls,and the differential proteins are mainly related to cholesterol metabolism,complement,and the coagulation cascade.
