Objective To observe the effects of irbesartan and amlodipine on insulin sensitivity in obese hypertensive patients. Methods 157 moderate hypertensive patients were divided into two greups,which received irbesartan or amlodipine for 16 weeks. The changes of blood pressure,heart rate and weight were observed. Insulin re-sistance was computed using the homeostasis model assessment (HOMA-IR). Results There was no difference in antihypertensive efficacy between the two groups(P>0.05). After 16 weeks of treatment ,the insulin resistance index decreased by 8.7±2.4 vs 6.1±2.6 (P<0.01) and body mass index decreased(28.1±3.8) kg/m2 vs (27.2± 3.2 ) kg/m2 (P<0.05 ) and mean heart rate raised by (73.1 ±10.0 ) kg/m2 vs ( 79.1±11.4) kg/m2 ( P < 0.01 ) in irbesartan group while no such changes were found in amlodipine treated group. Conclusions In obese hypertensive patients,irbsartan and amlodipine exert similar antihypertensive effect, but irbesartan may help to improve some obe-sity-related metabolize disorder,so the obese hypertensive patients may benefit more from irbsartan than from amlo-dipine.

Objective To detect the proliferation of neural stem cells (NSC) and analyze the effects of taurine on NSC proliferation in rats with fetal growth restriction (FGR).Methods For in vivo experiment,pregnant rats were randomly divided into three groups:control group (n=5),FGR group (n=7) and taurine group (n=6) [treated with taurine,300 mg/(kg · d)].Rats in the latter two groups were fed with 40％ of food intake in control group throughout pregnancy to establish the FGR model.Fatty acid binding protein-7 (FABP-7) expression in brains was detected by immunohistochemistry.For in vitro experiment,pregnant rats were divided into two groups including control group and FGR group.FGR modeling was established in the same way as above.On the 14.5 day of pregnancy,NSC were isolated and cultured for five days to form neurospheres with different concentrations of taurine (control,0,5,10,15,20,30,40 mmol/L).Immunofluorescence staining was used to detect the expression of NSC-specific marker FABP-7.CCK8 test was used to detect the cell proliferating index.Neurospheres were collected at the end of culture and disaggregated to get the total number of viable cells.One-way ANOVA,Kruskal-Wallis Test,SNK-test and Tamhane's test were used for statistical analysis.Results Compared with the control group (18 012±3 016),the number of FABP-7-positive cells in FGR model group (10 173±1 728) was decreased (P＜0.05),but increased in taurine group (19 518±3 201) (F=200.8,P＜0.05).Free-floating neurospheres could be formed in both control and FGR groups and the cells within neurospheres were mostly FABP-7-positive and were then considered as NSC.The proliferation indexes in control,FGR,FGR+5 mmol/L taurine,FGR+10 mmol/L taurine,FGR+15 mmol/L taurine,FGR+20 mmol/L taurine,FGR+30 mmol/L taurine,FGR+40 mmol/L taurine groups were 1,0.80±0.07,0.92±0.11,1.33±0.24,1.20±0.15,1.11 ±0.14,0.80±0.12 and 0.82±0.08,respectively.The proliferation indexes in FGR groups treated with 10,15 or 20 mmol/L of taurine were significantly higher than that of FGR group without taurine interference (P＜0.05).The total cell numbers in the eight groups were (24.5 ± 0.6)× 105,(20.23 ± 1.09)× 105,(22.80 ±0.86) × 105,(27.53± 1.22)× 10s,(25.30±1.05)× 105,(22.70±0.72)× 105,(21.80± 1.80)× 105 and (18.06 ± 0.90)× 105,respectively.Compared with the FGR group without taurine interference,those treated with 5,10,15 or 20 mmol/L of taurine showed higher total cell numbers (all P＜0.05 or ＜0.01),while that treated with 40 mmol/L oftaurine was lower.Conclusions The number and proliferation of NSC in FGR fetal rat brains is significantly decreased,however,these could be reversed by antenatal supplementation of taurine.The best effect is shown when l0 mmol/L of taurine is given.

Objective To evaluate the feasibility of real-time triplane strain rate imaging for the quantitative assessment of left atrial function in normal subjects. Methods Totally 40 healthy volunteers were enrolled. Left atrial expansion index (LAEI), left atrial passive emptying fraction (LAPEF) and left atrial active emptying fraction (LAAEF) were measured using real-time triplane volume analysis. Mean systolic peak strain rate (MSRs), mean early diastolic peak strain rate (MSRe) and mean late diastolic peak strain rate (MSRa) were measured using real-time triplane strain rate imaging. The results were compared respectively. Results MSRs correlated positively with LAEI (r=0.61, P<0.01). MSRe correlated inversely with LAPEF (r=-0.67, P<0.01), so did MSRa with LAAEF (r=-0.78, P<0.01). Conclusion Real-time triplane strain rate imaging is feasible for the quantification of left atrial function in normal subjects.

Objectves To investigate the effectiveness and safety of bronchoalveolar lavage for the treatment of neonatal pulmonary atelectasis under ultrasound monitoring.Methods Thirty-two neonates diagnosed with pulmonary atelectasis by lung ultrasound,and hospitalized in the Neonatal Intensive Care Unit of Bayi Children's Hospital,the General Hospital of the Chinese People's Liberation Army between July 2014 and June 2016,were included in this study.Bronchoalveolar lavage was performed in all the patients by injection of lavage fluid (0.9％ NaC1 or 0.9％ NaCl plus ambroxol hydrochloride and/or exogenous pulmonary surfactant) 1.5 to 3.0 ml via tracheal intubation.Lung ultrasonography was performed immediately after each lavage to reveal the status of lung recruitment.Repeated lavage one to three times made up of one course of treatment.The bronchoalveolar lavage could be performed for one to two courses daily according to the status of atelectasis recovery.Medical records were reviewed to analyze descriptively the effectiveness,side effects and complications of the bronchoalveolar lavage.Results Bronchoalveolar lavage was significantly effective in 25 patients (78.1％) with disappearance of pulmonary atelectasis after one course of treatment;effective in five cases (15.6％) with disappearance or reduction of atelectasis after two or three courses;with a total effectiveness rate of 93.8％(30/32).Bronchoalveolar lavage was ineffective in two cases (6.2％) with no remarkable change in atelectasis after three courses of treatment.Vital signs were stable in all the infants during the bronchoalveolar lavage,and no adverse effects and complications occurred.Conclusions Bronchoalveolar lavage is effective for the treatment of neonatal pulmonary atelectasis under ultrasound monitoring,and it is easy to operate and with no adverse effects and complications,and thus worth of clinical application.

Objective To explore the effect of continuing care on the intermittent catheterization compliance of patients with neurogenic bladder. Methods From January to December, 2015, 60 patients with neurogenic bladder after spinal cord injury receiving intermittent cathe-terization were randomly assigned to control group (n=30) and intervention group (n=30). The control group received routine discharge in-struction, while the intervention group received continuing care in addition. The intermittent catheterization compliance, residual urine vol-ume, urinary tract infection and quality of life were assessed at discharge and three months after intervention. Results After intervention, the intermittent catheterization compliance was better in the intervention group than in the control group (χ2=7.500, P=0.006). The residual urine volume significantly decreased in both groups (t>12.040, P<0.001), and was less in the intervention group than in the control group (t=-2.190, P=0.032), as well as the urinary tract infection rate (χ2=10.800, P=0.001). The score of quality of life increased significantly after intervention in both groups (t>4.572, P<0.001), and was higher in the intervention group than in the control group (t>5.505, P<0.001). Con-clusion Continuing care could improve the intermittent catheterization compliance, reduce the residual urine volume and the urinary tract in-fection rate, and improve the quality of life in patients with neurogenic bladder after discharge.

Objective To study the effect of astragaloside on proliferation and apoptosis in human keloid fibroblasts.Methods The human keloid fibroblast ceils were treated with different concentration of astragaloside(10、20、40 ng/mL).Cell proliferation was detected by MTT,the gene expreesion levels and protein levels of apoptosis-related proteins,survivin,p53 and Bcl-2.were determined by real-time PCR and Western blot,respectively.Results Comparecl with control group(treated with 0 ng/mL astragaloside),the absorbance values (A490 nm) of each concentration group were significantly reduced,which suggest that the proliferation of all keloid fibroblast were markably inhibited in a dose-dependent way (P＜0.05).The gene expreesion levels and protein levels of apoptosis-related proteins,survivin、Bcl-2 were largely suppressed and P53 werelargely promoted in a dose-dependent.Conclusion The keloid fibroblasts cells proliferation and apoptosis could be regulated by astragaloside.
