Objective:To study the influence of transcatheter closure combined drug intervention on levels of brain na-triuretic peptide (BNP)and vascular endothelium (ET)in children with congenital heart disease (CHD)complicated pulmonary artery hypertension (PAH).Methods:A total of 70 CHD + PAH children from Mar 2011 to May 2013 in our hospital were enrolled.According to random number table,they were equally divided into transcatheter clo-sure combined drug intervention group (combined treatment group)and transcatheter closure control group (only re-ceived transcatheter closure therapy).Cytokine levels and heart function indexes were observed and compared be-tween two groups.Results:Compared with transcatheter closure control group after treatment,there were signifi-cant reductions in levels of BNP [(352.7±56.2)ng/L vs.(194.5±25.2)ng/L]and vascular ET [(68.4±8.4)ng/L vs.(37.5±5.2)ng/L,P <0.01],and significant rise in left ventricular early diastolic peak filling velocity [E, (63.7±6.9)cm/s vs.(71.7±7.4)cm/s],left ventricular early/late diastolic peak filling velocity [E/A,(1.10± 0.13)vs.(1.34±0.16)],left ventricular ejection fraction [LVEF,(62.3±7.6)% vs.(66.4±7.1)%]and left ventricular end-diastolic diameter [LVEDd,(48.9±5.7)mm vs.(54.1±5.8)mm]in combined treatment group, P <0.05 or <0.01.Conclusion:Transcatheter closure combined drug intervention can reduce BNP and vascular ET concentrations,improve heart function,which possesses positive clinical application value.

Objective To investigate the relationship of mental health and the personality traits of higher vocational college students. Methods Using CCSMHS and NEO-FFI,679 higher vocational College Students from 4 Hunan Vocational College were investigated. Results ①A few people of higher vocational college students had obvious psychological symptoms,and more people were in a state of sub-health. ②The personality trait of female higher vocational college students is different from that of the male significantly. There is no significant difference between different grades and different disciplines. ③There was a significant relation between the mental health of higher vocational college students and a number of personality traits. Conclusion The personality traits are the main factors influencing mental health of higher vocational college students.

Objective To investigate the protective effect of osthole on focal cerebral ischemia-reperfusion injury in rats.Methods Focal cerebral ischemia-reperfusion model in rat was made by transient occlusion of the middle cerebral artery for 2 h and followed by reperfusion for 24 h.Osthole 5 and 10 mg/kg were iv injected through sublingual vein at 1 h after the onset of ischemia,respectively.After 24 h of reperfusion,the influence of osthole on neurological behaviour deficit score,brain edema,and infarct size were evaluated.The activity of Na+,K+-ATPase,Ca2+-ATPase,and myeloperoxidase(MPO)in the ischemic hemisphere cortex of the middle cerebral artery area was assayed by spectrophotometry.The level of IL-8 was detected with radioimmunoassay.Results Osthole significantly reduced the neurological behaviour deficit score,brain edema,and infarct size,enhanced the activity of Na+,K+-ATPase and Ca2+-ATPase,inhibited the activity of MPO,and decreased the level of IL-8 in the brain tissue.ConclusionThe results suggest that osthole could attenuate the brain damage following focal cerebral ischemia-reperfusion in rats and its mechanism may be partly related to the inhibition of inflammation and brain edema induced by ischemia-reperfusion.

To explore the kinetics of LBP/CD14 system in patients with hemodialysis, and further to analyse its role in (he development of systemic inflammation response based on the changes of plasma endotaxin, TNF and IL-6 levels in patients with uremia treated with hemodilysis. Methods Sixteen patients with end-stage renal failure (8 cases with hemodialysis, 8 cses without hemodialysis) were selected for this study. limulus amebocyte lysate chromogenic assay, ELISA and cell in situ hybridization were used to determine the changes in endotoxin, LBP, TNF and IL-6 levels in plasma, and expression of CD14 mRNA in the monocytes. Results (l)Plasma LBP levels in patients with hemodialysis were significantly higher than those in patients without hemodialysis. The expression of CD14 mRNA in the monocytes in patients with hemodialysis was also more obvious. Both of them incresed much more in hemodialysis. (2)Plasma endotoxin levels in patients with hemodialysis, though being significantly higher than in patients without hemodialysis, were in low-level (61.7 ? 10.6 pg/ml). (3) Plasma TNF and IL-6 levels were markedly increased in patients with hemodialysis, which were significantly correlated with plasma LBP levels. Conclusion LBP/CD14 system in patients with hemodialysis is markedly up-regulated, which might be the important mechanism for low-level endotoxemia to exert its effects in hemodialysis.

AIM To investigate the significance of CGRP and ET in the coronary syndrome and the significance of their changes in the incidence of the acute coronary syndrome.Methods Group with UA group ( n =30), AMI group ( n =28), control group ( n =25) were established.In control group blood sample take on an empty stomach in the morning ,while group with AMI on hospitalization and after one week, group with UA at angina pectoris attack and after remission. The concentration of plasm CGRP and ET were measured .Results The plasm CGRP concentration in group with AMI was higher than that in group with UA and that in control group ,the plasm ET elevated markedly, while the rate of CGRP/ET decreased; Compared with that in the remission period of the acute coronary syndrome ,The plasm CGRP elevated, the plasm ET elevated markedly, while the rate of CGRP/ET decreased.Among defferent acute coronary syndrome ,the plasm CRGP and ET concentrantion was highest in AMI group,higher in group with accelerated UA, high in group with initial attack UA;the rate of CGRP/ET was highest in group with initial UA,higher in group with accelerated UA,high in group with AMI.Conclusions The changes of plasm CGRP and ET concentration are well correlated with the extent of coronary lesion, the level of plasm CGRP and ET and the imbanlance of thier receptor play an important role in the pathogenesis and development of acute coronary syndrome.

Methods The effects of VLDL concentration, apoE ligand activity and scavenger receptor A (SRA) on the binding of 125 I VLDL to monocyte macrophages were analysed. The influence of VLDL on SRA mRNA and protein expression and VLDL receptor gene translation was probed. Results (1) The differentiated monocyte macrophages induced 125 I VLDL uptake by dose dependent pathway( r =0 71, P

Objective To investigate effect of sorafenib on serum hepatoma marker in patients with advanced hepatocellular carcinoma. Methods 101 patients with advanced hepatocellular carcinoma were selected, and divided into two groups.50 cases in control group were treated with routine clinical treatment, and 51 cases in experimental group were treated with sorafenib on the basis of control group.The survival time, adverse reactions, VEGF, CTGF, HIF-1 and OPN levels were compared after the treatment.Results The survival time of experimental group was higher than control group (P<0.05).Compared with control group, the serum levels of VEGF、CTGF,HIF-1, OPN,AFP, CEA, and CA199 in experiment group were lower (P<0.05,P <0.01).There were no significant differences of total adverse reactions between experimental group and control group. Conclusion Sorafenib can effectively prolong survival time of patients with advanced hepatocellular carcinoma, reduce serum VEGF, CTGF, HIF-1 alpha and OPN levels.
