Objective To investigate the effect of brain natriuretic peptide (BNP) on serum angiotensin-converting enzyme (ACE) 2 levels in acute heart failure patients with reduced ejection fraction (HFrEF). Methods A total of 106 patients with acute HFrEF were selected, and were divided randomly into control group and trial group. The control group was under routine treatment, while the trial group was under routine treatment combined with lyophiluzed recombinant human BNP for 24-hour. Cardiac functional parameters were measured by echocardiography both at the enrollment and the end of 7-day treatment. Serum levels of ACE2 and N-terminal pro-BNP (NT-proBNP) were determined using commercially available ELISA kits at the enrollment, the end of 24-hour treatment, and the end of 7-day treatment,respectively. Results A total of 103 patients with acute HFrEF were enrolled (control group=51, trial group=52). There were no significant differences in the use of drugs (e.g., aspirin) and serum biochemical indices (e.g. cardiac troponin I, creatinine) before treatment between these two groups. Compared to systolic blood pressure (SBP) at admission, SBP on the second day after treatment were significantly decreased in two groups (P<0.05). Compared to left ventricular ejection fraction (LVEF) at admission, LVEF values were significantly elevated on the seventh day after treatment in two groups ( P<0.05). There were no significant differences in SBP, diastolic blood pressure (DBP), and LVEF at admission between these two groups (P>0.05);there were also no significant differences in DBP on the second day after treatment, and LVEF on the seventh day after treatment (P>0.05), while SBP was significantly higher on the second day after treatment in control group than that of trial group (P < 0.05). Serum levels of NT-proBNP were decreased with the prolongation of time in two groups. Serum levels of ACE2 were decreased with the prolongation of time in control group, while were increased initially following decreased (which were still higher on the seventh day after treatment than that at admission) with the prolongation of time in trial group. Serum levels of NT-proBNP were higher after 2 days treatment or 7 days of treatment in control group than those of trial group, while serum levels of ACE2 were decreased after 2 days of treatment or 7 days of treatment in control group than those of trial group (P<0.05). Conclusion Patients with acute HFrEF may benefit from BNP by increasing serum ACE2 levels.

Objective To study whether Helicobacter pylori CagA protein can control gastrin gene expression and the detailed mechanism. Methods First, pcDNA3. 1ZEO (-)/cagA7 was transfected into gastric cancer cell lines AGS and SGC-7901 cells. At the same time, culturing the Helicobacter pylori NCTC11637 and infecting AGS and SGC-7901 cells with it. Next, in the infected and transfecled AGS and SGC-7901 cells, respectively adding the JAK2 signaling pathway inhibitor AG490 and the ERK signaling pathway inhibitor U0126 to inhibit the two signaling pathway. Untreated gastric cancer cells and empty vector transfected cells as the control. Using real-time fluorescence quantitative PCR to detect the levels of gastrin mRNA in transfected and infected cells. Results After AGS and SGC-7901 cells were transfected with pcDNA3. lZE0(-)/cagA7 and infected with NCTC11637, the results showed that the expression of gastrin mRNA increased significantly (P ＜ 0. 05) in transfected and infected cells as compared with the control group, but after adding the inhibitor AG490 and U0126 respectively, the expression of gastrin mRNA decreased significantly(P＜0.05). Conclution These results suggest that CagA may up-regulate the expression of the gastrin gene, and CagA is one of the important proteins in regulating gastrin gene expression. The ERK/MAPK and JAK/STAT signaling pathways may be involved in controlling of gastrin gene expression by CagA.

Percutaneous coronary intervention (PCI) is becoming a common practice in the treatment of patients with coronary heart disease (CHD) of all age.Depression is considered to be a risk factor for the development of CHD and deteriorates the outcome after cardiac rehabilitation efforts.The aim of our study was to evaluate the presence of clinically relevant anxiety and depression in patients before and after PCI.Additionally we evaluated their relationship to age because of the increasing number of elderly patients undergoing PCI.Methods One hundred and twelve consecutive patients in three Sanatoria for Retired Cadres in Beijing who underwent PCI were asked to fill in the Hospital Anxiety and Depression Scale (HADS) to measure depression and anxiety scores two days before and ten days after PCI.Differences between these pre- and post-surgical scores were then calculated as means for changes,and the amount of elevated scores was appraised,in order to investigate the relationship between age and anxiety and depression,respectively,Spearman correlations between age and the difference scores were calculated.In addition,ANOVA procedures with the factor age group and McNemar tests were calculated.Results 25.8% of the patients were clinically depressed before and 17.5% after PCI;34.0% of the patients were clinically anxious before and 24.7% after PCI.This overall change is not significant.We found a significant negative correlation between age and the difference between the two time points for anxiety (Spearman rho = -.218,P = 0.03),but not for depression (Spearman rho = -.128,P = 0.21).ANOVA and McNemar tests revealed that anxiety scores and the number of patients high in anxiety declined statistically meaningful only in the youngest patient group.Such a relationship could not be found for depression.Conclusions Our data show a relationship between age and anxiety.Younger patients are more anxious before PCI than older ones and show a decline in symptoms while elderly patients show hardly any change.(J Geriatr Cardiol 2008;5:203-206)

Objective To explore the differences of occupation burnout of the soldiers in southern and northern Xinjiang and explore its related influencing factors.Methods Using stratified randomization sampling method,500 soldiers from south and north of xinjiang military were selected and investigated by Military Job Burnout Scale and Military Social Support Rating Scale.Results ① The military of northern soldiers'accomplishment,somatization,interpersonal relationship,social support score (5.57±3.29,5.53± 3.35,3.38±2.75,9.62± 10.15) was significantly higher than the soldiers who live in south of xinjiang (5.26±3.25,5.13±3.45,2.94±2.39,6.25±5.24) (t=2.091,-2.539,-4.011,7.227,P＜0.05).②Every dimensions of occupation bumout has significant correlation with social support,age,length of military service,marriage,level,working hours,income and job satisfaction (r=0.124,0.220,0.275,0.198,0.192,0.206,0.188,-0.383,P＜0.05).The total score of Military Job Bumout Scale has positive correlation with social support and level (r=0.122、0.410,P＜0.01).③Social support,working hours,job satisfaction and length of military service has forecast effect on the northern military occupation bumout.Social support and level can predict the southern military occupation burnout.Conclusion It is no obviously differences on the general occupational between the north and South Xinjiang Military.Social support is closely related to the job burnout of South and the North military.

Objective To study the mechanism of anti-aging effect of dimethylaminoethanol (DMAE) and compound amino acid (AA) injection by mesotheray in D-galactose-induced skin aging rat.Methods Eighty rats were randomly divided into aging treatment group (60 cases),aging control group (10 cases) and normal control group (10 cases).The skin aging models were established by subcutaneous infectim of D-galactose.From the 18th day,the aging treatment group were injected intradermally in the rats' both sides hip skin with 0.2％ DMAE+ AA,0.1％ DMAE+AA,0.2％DMAE,0.1％ DMAE,AA,and saline,once a week.After four weeks,HE,water content,superoxide dismutase (SOD) activity,hydroxyproline (HYP) and malondialdehyde (MDA) content were measured.Results Compared with the aging control group,the epidermal and the dermal thickness and the collagen area of rats skin' increased significantly in 0.2 ％ DMAE+ AA and 0.1％ DMAE+ AA treatment groups (P＜0.05).0.2％ DMAE+AA and 0.1 ％ DMAE+AA treatment groups also had higher SOD activity,HYP content and lower MDA content than other groups (P＜0.05),but no difference was noted among normal control group,0.2％ DMAE+AA and 0.1％ DMAE+AA group (P＞0.05).There were no differences in water content among groups (P＞0.05).Conclusions Intradermal injection with 0.1％ DMAE+ AA and 0.2 ％ DMAE+AA in aging rats may increase the epidermal and the dermal thickness and the collagen of rats skin' improve SOD activity,HYP content and decreased MDA content,indicating that it has ability to clear skin free radicals,enhance antioxidant capacity and skin collagen metabolism,and thus prevent skin aging.
