Objective To investigate the relationship between flow-mediated dilatation of the brachial artery(FMD) and cardiovascular risk factors as well as target organ damage in elder patients with isolated systolic hypertension(ISH).Methods Ninety patients with ISH were divided into two groups: ISH group(n=51) and ISH with hyperlipidemia group(n=39).Color Doppler ultrasound for FMD was performed on all the patients,and carotid artery ultrasound and cardiac ultrasound were also conducted. Results Patiens with hyperlipidemia had lower FMD than those of ISH group(P=0.021).It was revealed by univariate analysis that FMD was negatively related to systolic blood pressure,carotid intima-media thickness and total cholesterol(P

This study was aimed to evaluate the efficacy of Tiao-Bu Fei-Shen therapies (i.e., Bu-Fei Jian-Pi, Bu-Fei Y i-Shen, Y i-Qi Zi-Shen) on cardiac remodeling of chronic obstructive pulmonary disease (COPD) rats and its mechanisms according to the R-value comprehensive evaluation method. Based on the database of previous experiment of COPD rats, R-value comprehensive evaluation method was used to evaluate the indexes as fellows to discuss efficacy of Tiao-Bu Fei-Shen therapies on cardiac remodeling of COPD rats. ① Indicators of right ventricular morphologic indexes: right ventricular hypertrophy index (RVHI), cardiac muscle sarcomere lengths, bulk density of myocardial mitochondria (Vv), surface area (δ), membrane surface (δm), Vv, δ, δm of heart mitochondria;② Indicators of mechanisms: right ventricular endothelin-1 (ET-1), transforming growth factor-beta ( TGF-β) , vascular endothelial growth factor ( VEGF ) , basic fibroblast growth factor ( bFGF ) , matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1). The results showed that the sequence of improving effect of right ventricular remodeling at week 20 was Bu-Fei Jian-Pi, Bu-Fei Y i-Shen, aminophylline, and Y i-Qi Zi-Shen; at week 32 and the integrated week 20 and week 32, the sequence of effect was Bu-Fei Jian-Pi, Bu-Fei Y i-Shen, Y i-Qi Zi-Shen, and aminophylline. At integrated week 20 and week 32, Bu-Fei Jian-Pi had significant better intensity correcting effect than aminophylline (P< 0.01). There was no difference between week 20 and week 32. It showed that each treatment group had good long-term effect. For the mechanism of correcting effect on right ventricular remodeling, at week 20, the sequence of comprehensive effect was Bu-Fei Jian-Pi, Bu-Fei Y i-Shen, aminophylline, and Y i-Qi Zi-Shen. And Bu-Fei Jian-Pi had better effect compared with aminophylline and Y i-Qi Zi-Shen (P< 0.01); Bu-Fei Y i-Shen had better effect than Y i-Qi Zi-Shen (P< 0.05). At week 32, the sequence of effect was Y i-Qi Zi-Shen, aminophylline, Bu-Fei Jian-Pi, and Bu-Fei Y i-Shen. At the integrated week 20 and week 32, the sequence of effect was Bu-Fei Jian-Pi, and Bu-Fei Y i-Shen, Y i-Qi Zi-Shen, and aminophylline. Until week 32, the correcting effect of Tiao-Bu Fei-Shen therapies and aminophylline still maintained the same level as at week 20. It indicated that each treatment plan had good long-term effect. It was concluded that Tiao-Bu Fei-Shen therapies can improve the cardiac remodeling of COPD rats and expression of related factors in the cardiac remodeling through the R-value comprehensive evaluation method. And the effect of Bu-Fei Jian-Pi was obvious with good long-term effect.

Objective To explore a safe and high efficiency way of gene transfection of autocrine motility factor(AMF) in order to provide experimental basis for transplantation of myoblasts carrying AMF gone. Methods Sprague Dawley rat myoblasts were cultured, purified, proliferated and immunohisto-chemically verified. Then, the myoblasts were transfected with AMF and eGFP (enhanced green fluores-cent protein) gene by FIV (feline immunodeficiency virus). Fluorescence microscope and laser scanning confocal microscope were employed to detect eGFP so as to verify positive transfection rate. Expression of AMF was detected by immunohistochemical method. Results Myoblasts with 98% purity could he ob-tained after two weeks of primary culture and purification. Positive transfection rate reached 90.4% when MOI (multiplicity of infection) was 100 (P <0.01). The transfected AMF gene could express normally. Conclusions Explant culture is a proper way in rat myoblast culture. Meanwhile, AMF gene can he effectively transfected into rat myoblast and well expressed via FIV.

Objective To access the left internal thoracic artery (LITA) graft late postoperative patency after coronary artery bypass grafting (CABG) by peripheral blood vessel ultrasound combined with color Doppler coronary flow imaging (CDCFI).In contrast with angiography,try to find available flow parameter to access graft patency.MethodsForty-six patients with CABG more than 1 year postoperatively followed-by angiography were detected by ultrasound.The LITA graft and left anterior descending artery were examined.Systolic and diastolic peak velocity(Smax,Dmax),velocity time integral(VTIs,VTId)of each segment were measured separately.The ratio of diastolic and systolic peak velocity (D/S),and diastolic velocity time integral fraction(DVTIF) were calculated.All patients were divided into groups according to angiography results.ResultsThirty -one LITA grafts were patent,11 were dysfunctional,4 were occlusive.According to the angiography results,the flow parameters of the proximal segment of LITA graft were significant.The D/S and DVTIF of patent group was higher than that of dysfunctional group.The diastolic peak velocity of distal segment of LAD of patent group was higher than that of dysfunctional group.ConclusionsPeripheral blood vessel ultrasound combined with CDCFI could provide the evidence to access the patency of the graft.It was an effective method for the clinical follow-up.

OBJECTIVE:To construct the structure equation model for the burden of chronic disease inpatients in primary hos-pital before and after the implementation of zero price policy,and analyze the changes of burden factor loading. METHODS:6 pri-mary hospitals were randomly selected in Danyang,Jiangsu province. The data of hospitalization expenses for chronic diseases(hy-pertension,diabetes,bronchitis)were collected before and after the implementation of zero price policy. Using drug cost,nursing fees,inspection fees and treatment fees as independent variables,hospitalization burden as latent variable,SPSS and AMOS 24.0 software were adopted to establish the model. RESULTS:The burden factor loading of inpatients changed greatly before and after the implementation of zero price policy. χ2=24.586,χ2/df=1.446, RMSEA=0.019,GFI=0.995,AGFI=0.989,CFI=0.988,NFI=0.963 manifested good model fitting. Factor loading of drug cost increased greatly,indicating the burden of inpatients was reduced after the implementation of zero price policy. Factor loading of inspection fees and treatment fees increased significantly,the charac-terization effects of them to the burden of inpatients were enhanced. Factor loading of nursing fees was the lowest,and it had the weakest effects on the burden of inpatients,of which the government should enhance the regulation. CONCLUSIONS:Established model has good reliability and validity. It can reflect the change of burden factor loading of inpatients before and after the implemen-tation of zero price policy.

Objective To analyze and discuss the negative effects of atomization inhalation in mechanical ventilation patients in intensive care unit. Methods A retrospective study of all the mechanical ventilation patients in the general ICU of our hospital was carried out from Aprilto December 2015. The risk of multidrug-resistant organisms(MDROs)colonizationin the lower respiratory tract and ventilation associated pneumonia(VAP)in mechanical ventilation patients were analyzed. Results A total of 922 patients were monitored, 160 of whom had atomization inhalation, 92 for MDROs colonizationin the lower respiratory tract and 18 for VAP. The rates ofatomization inhalation in patients with and without MDROs colonizationin the lower respiratory tract were 30.4%(28/92)and 15.9%(132/830)with statistical difference (χ2=12.193, P=0.000). And those in patients with and without VAP were 50.0%(9/18) and 16.7%(151/904), with statistical difference (χ2=11.420, P=0.000). Atomization inhalation was the independent risk factor both of MDROs colonizationin the lower respiratory tract(OR=1.917, 95%CI1.163-3.159, P=0.011) and VAP(OR=4.613, 95%CI 1.773-12.002, P=0.000) in mechanical ventilation patients. Conclusions Atomization inhalation may increase the risk of MDROs colonizationin the lower respiratory tract and VAP in mechanical ventilation patients. Thus unnecessary and too frequent operations of atomization inhalation should be decreased.

Objective To analyze the effect of prevention and treatment with lamivudine in HBsAg positive renal allograft recipients with HBV recurrence.Methods In 28 patients with chronic renal failure whose HBsAg was positive,8 cases were positive for HBV-DNA positive.All these 28 cases had normal liver function without hepatic cirrhosis before renal transplantation.All donors were negative for HBsAg.Twenty patients received lamivudine prophylactic treatment:14 cases positive for HBsAg but negative for HBV-DNA before transplantation received lamivudine treatment immedia- tely after transplantation and 6 cases positive for both HBsAg and HBV-DNA received lamidudine treatment before transplantation.Eight patients were treated with lamivudine when their hepatic dys- function with recurrent HBV antigenemia were developed after transplantation.Lamivudine was orally taken and its initial dosage was 100 rag/day.Results The follow-up period of the 28 patients were 13- 54 months with the average of 23.6 months,and 2 died during this period.Mild hepatic dysfunction with recurrent HBV antigenemia developed in 3 of 20 hepatitis antigenemia patients received lamivu- dine prophylactic treatment with a mean duration of 9.3 months after transplantation.The highest average level of serum ALT was 87.5 U/L.The liver function returned to the normal with HBV-DNA negative after lamivudine treatment in 3 patients.The other 17 patients maintained normal liver func- tion with HBV-DNA negative during the follow-up period.Hepatic dysfunction with recurrent HBV antigenemia(or HBV-DNA titer increased significantly)developed with a mean duration of 4.6 months in all 8 patients without receiving lamivudine prophylactic treatment.The highest average level of serum ALT was 174.5 U/L.The liver function returned to the normal with HBV-DNA negative after larnivudine treatment in the 8 cases.HBV-DNA,however,reappeared in 5 eases without any dis- continuation of lamivudine.The creatinine level remained normal without any severe drug side effects in 28 patients during lamivudine treatment.Conclusion Lamivudine treatment before hepatic dysfunc- tion might be a safe and effective strategy for prevention of recurrence of hepatitis B viremia in HBsAg positive renal allograft recipients.
