Objective To investigate the correlation between carotid artery plaque and blood pressure variability (BPV) in elderly patients with hypertension.Methods One hundred sixty elderly patients with hypertension were divided into plaque and non-plaque groups according to the results of carotid artery ultrasonography.All the patients were measured by ambulatory blood pressure monitoring.The mean blood pressure,mean pulse pressure,and blood pressure variability coefficient of two groups were calculated and compared during whole day,daytime,and nighttime.The related factors of carotid artery plaque were analyzed by multivarite logistic regression analysis.Results The 24 h systolic blood pressure standard deviation,daytime and nighttime of systolic blood pressure standard deviation,daytime diastolic blood pressure standard deviation of plaque group were higher than those of non-plaque group (P ＜ 0.05).The 24 h systolic blood pressure variation (24 h SBPV) and night systolic blood pressure variation (nSBPV) were higher than those of non-plaque group (P ＜0.01).Multivariate regression analysis results showed that carotic artery plaque was associated positively with 24 h BPV and blood pressure variability coefficient of nighttime (P ＜ 0.05).Conclusions The elderly hypertensive patients with carotid artery plaque is associated positively with 24 h systolic blood pressure variability coefficient and blood pressure variability of nighttime.

Objective To explore the effects of smoking on serum paraoxonase1 (PON1) activity and carotid atherosclerosis.Methods 478 subjects from residents of health screening for cardiovascular disease were enrolled from June 2012 to July 2014 in Huangpu district,shanghai.Smoking,drinking,exercise and cardiovascular disease risk factor data were recorded and gathered.All subjects accepted carotid artery ultrasound examination and were measured serum PON1 activity.The lowest quartile of serum PON1 activity level was taken as low PON1 activity level.Results (1) Serum PON1 activity in smokers was lower than that in non-smokers ((206.5±25.6) kU/L vs (230.9±38.1)kU/L,P＜0.01),incidence of carotid artery atherosclerosis in smoking group was higher than non-smoking group(75.7％ vs 56.1％,P＜0.01).(2) Multivariate logistic regression analyses indicated smoking,lack of exercise,creatinine,LDL-C were the independence factors of PON1 activity.(3) Multivariate logistic regression analyses indicated smoking,serum PON1 activity,age,gender,systolic pressure,were the independence factors of carotid atherosclerosis.Conclusion Smoking reduces serum activity.Smoking and lower serum PON1 activity level are independent risk factors of carotid atherosclerosis.

Objective To explore the optimal concentration of heparin sodium solution, which to seal up intravenous indwelling needle, in patients with Ⅳ thrombocytopenia. Methods A total of 90 patients withⅣthrombocytopenia who required intravenous indwelling needle were randomly divided into three groups which namely A, B and C groups with 30 cases each. A group was sealed up the tube of intravenous indwelling needle with 1 ml heparin sodium solution of 6.25 U/ml, B group with 12.50 U/ml and C group with 25.00 U/ml. The change of the platelet count, plasma prothrombin time (PT), activated partial thromboplastin time (APTT), plasma fibrinogen (Fbg) after extubation were observed in three groups and the incidence of blocking up and retention time were compared among three groups. Results The change of the platelet count, PT, APTT, Fbg were showed no statistical significance among three groups (P>0.05). The incidence of blocking up was 66.7%(22/30) in A group , 43.3%(13/30) in B group and 16.7%(5/30) in C group. They were showed statistical significance (χ2=15.000, P < 0.01). Retention time of tube above or equal to 3 days were observed respectively 13 person (43.3%,13/30) in A group, 21 cases(70.0%, 21/30) in B group, 25 patients(83.3%, 25/30) in C group. All above were showed statistical significance (χ2=11.000, P<0.01). Conclusions Heparin sodium 25.00 U/ml sealing up the tube of intravenous indwelling needle is safe in patient with Ⅳthrombocytopenia, which will reduce the ration of blocking tube and extend the life of tube.

The hemolysin production of 19 strains of Streptococcus spp. isolated from pigs in the Jiangsu and Shanghai regions in recent years were examined. Eight isolates of Streptococcus suis type 2 from Jiangsu showed weak hemolysis on blood agar, but a stronger reaction in Todd-Hewitt broth(THB). The hemolysin belonged to the group of thiol-activated hemolysins. Nine strains of Streptoccus equi subsp. zooepidemicus showed strong hemolysis on blood agar and in THB containing 5% new-born calf serum, but no hemolysis in THB alone. This hemolysin was similar to streptolysin S(SLS). Another two isolates were atypical members of Lancefield group C Streptococcus and showed strong hemolysis on blood agar and in THB with 5% new-born calf serum, but the hemolysin was unlike either streptolysin O or SLS.

OBJECTIVETo study the efficacy of Xiaoyao Powder (XYP) combined with interferon alpha (IFN-alpha) in treating HBeAg positive chronic hepatitis B (CHB) patients and the effect on their quality of life (QOL).

METHODSTotally 193 patients with HBeAg-positive CHB confirmed by liver biopsy were randomly assigned to 2 groups, Group A (94 cases) and Group B (99 cases). IFN-alpha1b was subcutaneously injected to patients in Group A at the dose of 50 microg, thrice per week. Those in Group B additionally took XYP. The therapeutic course for all was 24 weeks. Clinical efficacy was observed by assessing ALT restoration rate, HBeAg negative rate, HBeAg conversion rate, HBV DNA negative rate, complete response rate, partial response rate, and symptoms integral. The evaluation of QOL was performed by using chronic liver disease questionnaire (CLDQ) score. Adverse reaction occurrence rate was observed in the two groups.

RESULTSBetter effects were obtained in Group A on ALT restoration rate, HBeAg negative rate, HBV DNA negative rate, complete response rate, partial response rate, TCM symptoms integral, the total effective rate of TCM sysmptoms, CLDQ score, and adverse reaction rates, showing statistical difference when compared with Group B (P < 0.05, P < 0.01).

CONCLUSIONXYP could elevate the efficacy of TCM symptoms of HBeAg-positive CHB patients and anti-viral effect, improve their QOL, and reduce adverse reaction of IFN-alpha.

According to DNA sequences of the invA gene of Salmonella spp.,the phoA gene of Escherichia coli and the nuc gene of Staphylococcus aureus,three pairs of oligonucleotide primers were designed and synthesized to amplify the special DNA sequences by multiplex PCR. Moreover,the reaction conditions of multiplex PCR were optimized. The results showed the multiplex PCR using the three pairs of primers produced specific amplicons of expected sizes,284bp for Salmonella spp.,622bp for Escherichia coli,484bp for Staphylococcus aureus. The optimized reaction conditions followed as the concentration of primer 40nmol/L for Salmonella spp.,40nmol/L for Escherichia coli,80nmol/L for Staphylococcus aureus,2.4mmol/L Mg 2+ ,200?mol/L dNTP,1.5U Taq DNA polymerase,anneal temperature from 55.0℃ to 57.4℃. Under the condition,the detection limits for DNA template were 10.2pg,10.2pg and 102.0pg for Salmonella spp.,Escherichia coli and Staphylococcus aureus,respectively. The whole process could be completed within 4h. The multiplex PCR assay was a specific,sensitive,rapid and reliable method for detecting Salmonella spp.,Escherichia coli and Staphylococcus aureus,which establish important foundation for simultaneous detection for these three bacteria in food.
