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.
3.Serum Vitamin A is decreased in rheumatological diseases
Chinese Journal of Immunology 2017;33(7):1068-1071
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.

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 mechanism of effects of estrogen receptor (ER) on T and B lymphocytes in patients with SLE and synergistic effect of T and B lymphocytes in the pathogenesis of SLE.Methods Real-time fluorescence quantitative PCR was performed to detect the mRNA expressions of ER-α,interleukin 10 (IL-10) and B lymphocyte stimulator (BLyS) in peripheral blood mononuclear cells (PBMCs)from 40 SLE patients and 40 normal human controls. The clinical and laboratory correlation with the levels of these parameters was analyzed. Results A significant increase was observed in the relative expression levels of ER-α, IL-10 and BLyS mRNA in SLE patients compared with the normal human controls (P < 0.05 or 0.01 ), in active SLE patients compared with inactive SLE patients (P < 0.05 or 0.01 ). Additionally, the mRNA expression levels of the 3 parameters were significantly correlated with the presence of renal damage, proteinuria, arthritis, etc. No statistical difference was observed in the mRNA expression levels of these parameters between female and male patients or between female and male normal controls. Conclusions IL-10 and BLyS appear to be correlated with the disease activity and severity of SLE, and ER-α may play an important role in the action mechanism of T and B lymphocytes in SLE.

Objective To investigate the effects of continuous vennvenous haemodiafihration(CVVHDF)on major organ fimction and plasma cytokine levels in MODS dogs.Methods Fifteen Beagle dogs were subjected to hemorrhagic shock plus resuscitation and endotoxemia to establish MODS model,then dogs were randomly divided into 2 groups:CVVHDF group(n=8)and MODS group without CVVHDF (n=7).CVVHDF was performed for 12 hours after endotoxin injection in CVVHDF group dogs.Serum ALT,AST,Scr,BUN and blood gas were routinely measured,and plasma TNF-α,IL-6 and IL-10 coneentrations were measured by ELISA at different time points. Results Plasma levels of IL-6 and IL-10 were significantly decreased in the CVVHDF group at 3 h,6 h,9 h and 12 h after endotoxin injection as compared with MODS group (P<0.01).TNF-α levels were similar in both groups(P>0.05).IL-6 and TNF-α were detected in the ultrafihrate.The sieving coefficients (SC) for IL-6 and TNF-α were 0.27±0.13 and 0.1±0.1 respectively.IL-10 could not be detected in the ultrafiltrate.In CVVHDF group,function of major organs was improved.The beneficial effect of CVVHDF on the hypotension of MODS dogs was particularly striking at 6 h,9 h,and 12 h alter endotoxin injection(P<0.01).Mean PaO2 in CVVHDF groups at 3 h,6 h,9 h,and 12 h after endotoxin injection was significantly higher than that in MODS group(P<0.01). Conclusion CVVHDF effectively removes IL-6 and IL-10from the cireulation,attennates endotoxin-induced hypotension and improves arterial oxygenation in MODS dogs.
