AIM To evaluate the antagonizing activity of iQWcF, a modified tripeptide, to endothelin receptors. METHORDS ①Vasoconstriction experiments with aorta strips of rats. ② In vivo experiments:male normotensive Wistar rats were anesthetized with pentobarbital Na (50 mg?kg -1 ),and catheterized into the carotic artery for measurement of blood pressure, and into the femoral vein for administration of iQWcF (30 mg?kg -1 ) and ET 1(0 9 nmol?kg -1 ). The test compound was given intravenously 5 min before the bolus injection of ET 1. Control animals received saline on the same time schedule.The blood pressure was recorded at different time interval after injecting ET 1. RESULTS ①iQWcF prohibited the vascontriction of aorta induced by ET 1 in a concentration dependent fashion.②The compound(30 mg?kg -1 .iv) markedly antagonized ET 1 induced the long lasting pressor phase mediated by ET A without affecting early transient depressor phase by ET B. CONCLUSION iQWcF is one of ET A selective antagonists.

Objective To observe the perioperative management of cardiac surgery and extracorporeal circulation method in patients with glucose-6-phosphate dehydrogenase deficiency(G6PD).Methods Ten patients with G6PD deficiency underwent uneventful cardiac surgery procedures between January 2005 and December 2010.Twenty patients who had non-G6PD deficiency were as a control group,the selected conditions were the same gender,age,body mass,the risk of heart disease surgery.The preoperative management in patients with G6PD deficiency mainly focused on avoiding the drugs implicated in haemolysis,reducing the surgical stress,using moderate hypothermia extracorporeal circulation and enhancing blood conservation.Observed indicators included the assisted ventilation time,urine volume,the drainage volume of chest tube,the amount transfusion of red blood cells and plasma,the level of hemoglobin and serum total bilirubin in the 2nd day after surgery,ICU stay.Results Compared with the control group,patients with G6PD deficiency had no significant difference in duration of ventilation after the operation,drainage,urine,Hgb,bilirubin levels,and blood transfusion[(9.3 ± 4.5)h vs (8.6 ± 5.7)h,(2100 ±670)ml vs (1950 ± 490) ml,(253 ± 146)ml vs (260 ± 120)ml,(1.3 ± 1.0)U vs (1.8 ± 1.2)U,(96 ± 25)g/L vs (99 ± 12)g/L,and (24 ± 8)μmol/L vs (27 ± 1 l)μmol/L,t =0.978,2.032,1.257,0.891,2.182,2.271,and 1.329,all P ＞ 0.05].The duration of ICU discharge was significantly longer in the glucose-6-phosphate dehydrogenase deficient group[ (2.6 ± 0.6)d vs (1.8 ± 1.5)d,t =2.704,P ＜ 0.05].Conclusions Cardiac surgery can be performed safely in patients with G6PD deficiency with enhanced perioperative management.

Background Oxidative stress is thought to be responsible to diabetes-complicated cataract.Our previous study demonstrated that as an iron chelator,deferiprone can protect lens from oxidative damage.Objective This further study aimed to investigate the role of deferiprone on the formation of diabetic-complicated cataract.Methods Forty 6-week-old Wistar rats were included in the study and randomized into 4 groups.Eight of them were used as the normal control group.Diabetes mellitus animal models were established in 22 rats by the carbonhydratediet and fat diet and the intraperitoneal injection of 40 mg/kg streptozocin (STZ).The deferiprone of 50 mg and 100 mg were intragastrically given in 8 model rats respectively after 3 days once a day for 8 weeks.The opacification of lenses was examined under the slit lamp weekly after treatment.The animals were sacrificed and the lenses were obtained at the eighth week of deferiprone injection.The concentrations of water-soluble protein ( WSP),urine-soluble protein (USP) and alkali-soluble protein (ASP) in rat lens suspension were detected by Bradford method.The super oxide dimutese (SOD),malondialdehyde (MDA) and glutathione (GSH) were determined spectrometically using xanthine oxidase,thiobarbituric acid,dithio bis-nitrobenzoic acid.Results No evidently differences were found in the content of the WSP,USP and ASP among the these groups( F=1.73,0.18,0.09,P＞0.05).The contents of MDA in 50 mg deferiprone group and 100 mg deferiprone group were ( 1.05 ± 0.10 ) mmol/g and ( 1.05 ± 0.22 ) mmol/g respectively,showing a significant decline in comparison with diabetic model group (P＜0.05).The SOD and GSH contents in lens were (321.29±16.57) U/mg,(322.07±22.16) U/mg and (7.83±0.65 ) mg/g,(7.70±0.77 ) mg/g respectively in 50 mg deferiprone group and 100 mg deferiprone group and were considerably elevated in comparison with ( 298.70± 14.69 ) U/mg and ( 5.47 ± 1.01 ) mg/g of diabetic model groups ( P＜0.05 ).No significant differences were found in the indexes mentioned above between 50 mg and 100 mg deferiprone groups(P＞0.05).Conclusions Deferiprone can reduce oxidative stress and improve the energy metabolism of the lens in diabetic rats.

To evaluate the immunogenicity of inactivated SARS coronavirus (SARS-CoV), three groups of rabbits were immunized three times at 2-week intervals with inactivated vaccine + adjuvant, adjuvant,and normal saline respectively. Eight batchs of serum were sampled from the auricular vein at day 7 to day 51, and specific IgG antibody titers and neutralizing antibody titers were detected by indirect ELISA and micro-cytopathic effect neutralizing test. Antibody specificity was identified by proteinchip assay.Histopathological changes were detected by H&E staining. The results showed that, rabbits in the experimental group immunized with inactivated SARS-CoV all generated specific IgG antibodies with neutralizing activity, which suggested the inactivated SARS-CoV could preserve its antigenicity well and elicit an effective humoral immune responses. The peak titer value of specific IgG antibody and neutralizing antibody reached 1:40960 and 1:2560 respectively. In the experimental group, no obvious histopathological changes was detected in the H&E stained slides of heart, spleen, kidney and testis samples, but the livers had slight histopathological changes, and the lungs presented remarkable histopathological changes. These findings are of importance for SARS-CoV inactivated vaccine development.

Objective To provide an overview of the current knowledge of growth-differentiation factor 15 (GDF-15) in heart disease.Data sources To identify relevant publications,we searched PubMED database combining the textual terms of heart,cardiac,cardiovascular disease with GDF-15.Study selection Well-controlled,relatively large-scale,retrospective studies as well as meaningful individual cases were all selected as materials.Results GDF-15 is a distant member of the transforming growth factor-β cytokine superfamily.In myocardium,GDF-15 is weakly expressed under physiological conditions.However,its expression level is increased in response to pathological stress.Growing evidence indicate that elevated levels of GDF-15 is a promising prognostic biomarker in cardiovascular diseases.Moreover,GDF-15 exhibits the properties of endogenous anti-hypertrophy of cardiomyocytes and protecting the heart suffering from ischemia and reperfusion insult.Conclusion Ve GDF-15 may be a promising biomarker for evaluation and management of patient with cardiovascular diseases,and have potential protective properties on myocardium.

Objective To study the status and influencing factors on drug therapy compliance for the spinal tuberculosis patients after leaving hospital, so as to advance the corresponding nursing intervention strategies and to consolidate the cure effect. Methods 168 spinal tuberculosis patients in community were investigated by the basic information schedule table, compliance with regular treatment schedule table, the degree of disease cognition questionnaire, and the social support questionnaire. All questionnaires were collected and statistically treated. Results The scores of drug therapy compliance for the spinal tuberculosis pateints after leaving hospital were in a lower level, and the rate of compliance with regular treatment for spinal tuberculosis patients was 46.8%. The drug therapy compliance was affected by the years of age, the degree of disease cognition, the adverse reaction of medicine, the economy condition, the degree of civilization and the degree of social support (P <0.05). The drug therapy compliance was positively correlated with the degree of disease cognition, the economy condition, the degree of civilization and the degree of social support. The drug therapy compliance was negatively correlated with the years of age and the adverse reaction of medicine. Conclusions The druy therapy compliance for the spinal tuberculosis patients out of hospital is generally in a lower level Nursing stuffs should adopt active nursing interventions to raise the drug therapy compliance for spinal tuberculosis patients based on the influencing factors.
