Objective To study the clinical effects of aspirin and clopidogrel combined with atorvastatin calcium in patients with acute ischemic cerebrovascular disease. Methods 27 cases of patients with acute ischemic cerebrovascular disease from March 2015 to March 2016 in Hainan general hospital were selected,and randomly divided into control group and observation group,13 patients in the control group,treated with aspirin and clopidogrel,14 cases in the observation group,treat with atorvastatin calcium based on the control group,both two groups were treatment for three months.The total effective rate were compared between the two groups after treatment,NIHSS score and serum lipid level were compared before and after treatment. Results After treatment,the total effective rate of observation group was 92.9%,significantly higher than the control group 53.8%(P<0.05).Compared with before treatmeng,the NIHSS score of two groups were decreased,the levels of TC,TG and LDL-C in two groups were decreased,HDL-C was increased (P<0.05);Compared with control group,the NIHSS score of observation group was lower,TC,TG and LDL-C were lower,HDL-C was higher (P<0.05). Conclusion Aspirin and clopidogrel combined with atorvastatin calcium in treatment with acute ischemic cerebrovascular disease has significant effect,can reduce the patient's NIHSS score,improve blood lipid levels.

Objective:To investigate the serum Vitamin A(sVit A) levels in Behcet′s disease(BD)and other rheumatological diseases.Methods: sVit A concentration was measured in BD(including 3 subtypes of eye BD,intestinal BD,and vascular BD),rheumatoid arthritis(RA),systemic lupus erythematosus(SLE),ankylosing spondylitis(AS),primary Sjogren′s syndrome(pSS) and adult onset Still disease(AOSD)and compared with healthy controls(HC).Results: The patients enrolled in this study was according with the epidemiological features;BD patients including its subtypes of eye BD,intestinal BD,and vascular BD patients all had a lower concentration of sVit A than HC(P<0.05),no statistical differences between the subtypes;RA,SLE,AS,pSS and AOSD had a lower concentration of sVit A than HC(P<0.05).Conclusion: Decreased serum Vit A levels might account for a common pathogenesis of various rheumatic diseases.

The anesthesiology discipline development not only must comply with its own inherent laws of development,but also must focus on social,economical and the whole teaching environment of higher education as well as the discipline ecology evolution composed by neighbor discipline of anesthesiology.Its long term mechanism construction is discussed.

Objective To characterize the alteration in peripheral blood endothelial progenitor cells (EPCs) of patients with systemic lupus erythematosus (SLE).Methods Venous blood samples were obtained from 82 female patients with SLE aged (35 ± 10) years and 50 healthy female controls aged (35 ± 13) years.ACL 9000 automated coagulation analyzer was used to determine the level of Von Willebrand factor antigen (vWF Ag).Flow cytometry was performed to detect peripheral blood EPCs and circulating endothelial cells (CECs).Analysis of variance was performed to assess the differences in these parameters between patients with active and stable SLE and the controls,and Pearson correlation analysis was conducted to evaluate the relationship between these parameters.Results The number of CD34+ cells,CD133+ cells and CD34+CD133+cells per 200 000 peripheral blood mononuclear cells was 35.4 ± 16.7,86.5 ± 32.1 and 361.3 ± 176.4 in patients with active SLE,significantly higher than that in the patients with stable SLE (17.1 ± 10.9,28.7 ± 21.5,107.2 ±44.3,respectively,all P ＜ 0.01)) and the controls (13.8 ± 9.6,11.2 ± 5.5,92.3 ± 50.5,respectively,all P ＜0.01).The patients with active SLE exhibited an elevated level of vWF Ag (438.9％ ± 205.3％ vs.130.2％ ±51.5％,P ＜ 0.01),an increased number of EPCs (361.3 ± 176.4 vs.107.2 ± 44.3,P ＜ 0.01) but a similar number of CECs (127±51 vs.118 ± 39,P ＞ 0.05) per 200 000 peripheral blood mononuclear cells compared with the healthy controls.No significant differences were observed in these parameters between the patients with stable SLE and the controls (all P ＞ 0.05).The number of EPCs was positively correlated with the level of vWF Ag (r =0.67,P ＜ 0.01),but uncorrelated with the number of CECs (P ＞ 0.05) in patients with active SLE.Conclusions The quantity of EPCs in peripheral blood is closely correlated with the level of the vascular injury marker vWF Ag,hinting that the number of EPCs can serve as a useful marker of disease severity.

Objective: To optimize the sample pretreatment and establish an ultra-high-performance liquid chromatography coupled with hybrid quadrupole-orbitrap high-resolution mass spectrometry (UPLC-Q-Orbitrap-MS) assay based on the parallel reaction monitoring (PRM) mode for determination of antibiotic residues in chicken meat. Methods: Blank matrix-spiked chicken meat samples were extracted with 95% acetonitrile aqueous solution containing Na2EDTA and formic acid. The extraction solutions were cleaned up using different combinations of C18, PSA and GCB fillers, and the combinations with a higher antibiotic recovery rate was screened. The residues of 32 antibiotics were determined using UPLC-Q-Orbitrap-MS based on the PRM mode. Results: If the extraction solution was cleaned up using the C18 filler, the largest number of antibiotics with a spiked recovery rate of >80% was seen, with matrix effects of 82.2% to 112.6%. The detection limits of 32 antibiotics were 0.8 to 5.8 μg/kg, with linear correlation coefficients of >0.99, spiked recovery rates of 71.3% to 111.5% and relative standard deviations of 3.2% to 14.2%. Conclusion The UPLC-Q-Orbitrap-MS assay is suitable for determination and quantitative analysis of multiple antibiotics in chicken meat. Key words： high-resolution mass spectrometry orbitrap antibiotic residue parallel reaction monitoring

OBJECTIVE: To study the relationship among the dosage, serum concentration and clinical effect of phenytoin(PHT) in treating epileptic patients .METHODS: 130 steady -- state serum concentrations of PHT were determined by fluores-cence polarization immunoassay(FPIA) in 70 patients with or without other drugs used in combination .RESULTS: The indi-vidual difference among the patients who received routine dosage of PHT was very significant. Intoxication occurred ex-tremely often in patients whose PHT serum concentrations were over 30?g/ml .CONCLUSION: It is necessary to perform TDM(Therapeutic Drug Monitoring) and individualize the use of PHT,so that the safe and effective use of drug can be ensured.
