AIM:To explore the effect of erythropoietin ( EPO) on the expression of myocardial NADPH oxi-dase (Nox) in the pressure overload rats.METHODS:Male SD rats (n=36) were used to establish a pressure overload myocardial hypertrophy model by abdominal aorta ligation.The animals were divided into model group, control group ( sham, without narrowing abdominal aorta, the rest of the operation was the same as the model) and recombinant human erythropoietin ( rhEPO) treatment group ( intraperitoneal injection of rhEPO postoperatively, 4 000 U/kg, twice a week) . After 8 weeks, the cardiac ultrasound imaging and hemodynamic evaluation were conducted to determine the cardiac func-tions.Masson staining was used to observe the degree of myocardial fibrosis.The expression of Nox2 and Nox4 at mRNA and protein levels was detected by real-time quantitative PCR and Western blotting.The protein levels of myocardial inflam-matory factors CD45, F4/80 and TGF-βwere determined by Western blotting.RESULTS:Compared with model group, the left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS), left ventricular end-systolic pressure (LVESP) and left ventricular pressure maximum rising and falling rates ( ±dp/dtmax) increased significantly in EPO treatment group (P<0.01).At the same time, left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic diameter ( LVEDD) and left ventricular end-diastolic pressure ( LVEDP) were decreased in EPO treatment group (P<0.01).EPO reduced the degree of myocardial fibrosis caused by pressure overload (P<0.01) and decreased the ex-pression of Nox2 and Nox4 at mRNA and protein levels in the myocardium (P<0.05 or P<0.01), and reduced the pro-tein expression of myocardial inflammatory factors CD45, F4/80 and TGF-β.CONCLUSION: EPO inhibits rat myocar-dial fibrosis induced by pressure overload, improves heart functions by decreasing NADPH oxidase activity and inhibiting myocardial oxidative stress levels and myocardial inflammatory reaction.

Objective To compare the effects of oral Sildenafil(SIL)and intravenous prostaglandin E_1(Alprostadil,PGE_1)in treatment of postoperative pulmonary hypertension(PH)associated with congenital heart defects(CHD).Methods Data were collected from 24 children with postoperative mPAP≥35 mmHg in our hospital between August 2004 and March 2005.These children were randomly divided into three groups:8 children(group A)initially received SIL(0.35 mg/kg,orally by nasal gastric tube),followed by the addition of intravenous PGE_1(20 ng/kg per min)at 40 min.The second group of 8 children(group C)initially received intravenous PGE_1 followed by the addition of SIL at 20 min(dose as above).And remains(group B)were placebo-controlled.The changes of hemodynamic variables,arterial blood gas,lung static compliance(C)and work of breathing(W)were measured after drugs were given.Results Compared with group B,the mPAP and mPAP/mSAP was significantly reduced(P

The effect of Hippophae rhamnoides L. juice (HRJ) on the immunologic function and the inhibition of tumor growth in mice were reported. Kunming mice were administered orally with HRJ for 7 days. The IL-2 produced by splenocytes, the reactivity of splenocytes to IL-2 were markedly stimulated (P

To investigate the changes of activated platelet marker and its significance in older hypertensive patients, glycoprotein Ⅱb/Ⅲa(PAC 1)and P selectin(CD62P) were used as molecular markers for activated platelets,which were analyzed by flow cytometric 3 color immunofluorescence. The results showed that PAC 1 expression on platelet membrane surface in older hypertensive patients was higher than that in healthy individuals and was not related with mean blood pressure.However, the expression of CD62P on platelets membrane surface did not differ in the two groups.These results suggest that PAC 1 may be regarded as a sensitive and specific molecular marker for activated platelets. Platelet activation occurrs in older hypertensive patients, and is of great importance for the antiplatelet therapy in hypertensive patients.

Objective To investigate different clinicopathologic changes in myocardial infarction with and without cardiac rupture in the gerontal patients. Methods 107 gerontal patients with myocardial infarction (rupture group 22, non-rupture group 85) confirmed by necropsy during Jan. 1980 to Oct. 2003 were analyzed to compare the clinicopathologic findings between patients with cardiac rupture and without rupture. Results The mean age of rupture group was higher than that of non-rupture (79.1?9.1 vs 71.8?10.9 years old, P=0.0059). The number of female patients (50.0% vs 24.6%, P=0.0209) and the the number of patients suffering from myocardial infarction for the first time (57.3% vs 52.3%, P=0.0312) were both greater in the rupture group. Previous angina pectoris was significantly less frequently found in the rupture group compared with non-rupture group (45.5% vs 87.1%, P=0.0000). The mean number of major coronary arteries with over 75% stenosis was significantly lower in the rupture group (1.64 vs 2.28 branches/person, P=0.0068). The percentage of single major coronary arteries with significant stenosis was more often seen in the rupture group (59.1% vs 33.8%, P=0.0325). The site of cardiac rupture was more frequenfly located in anterior wall near the apex. Conclusion The results suggested that cardiac rupture occurred more often in older and female patients, in first myocardial infarction episode, with infrequent previous angina pectoris, and frequently involving a severe single coronary artery disease compared with those patients without cardiac rupture. The common location of rupture was anterior wall near the apex.

Objective:To summarize the development of the HIV/AIDS designated hospital system, analyze the main issues and explore solutions for this system. Methods:184 leaders/experts of three levels of healthcare facilities ( provinces, cities and counties) from 30 provinces engaged in AIDS prevention and control for over five years, and 2,432 people living with HIV/AIDS(PLWHA) from seven provinces were investigated through two different question-naires. Results:According to the staff responses, the issues of surgery and hospitalization are difficult and outstand-ing for PLWHA due to the current designated hospital system with scores of 6. 49 in severity. Of the ten largest prob-lems, ranked third is the need for improved AIDS prevention and control. 2 367 (97. 3%) PLWHAs had an aware-ness of the designated hospitals, 1,376 received treatment in the designated hospitals, and 85. 5% believed that the illness was effectively treated, while 9. 0% thought that the medical technology of the designated hospital was limited;18 . 7% of hospitalized HIV/AIDS patients or those who received surgery experienced prevarication by the non-des-ignated hospitals. Policy analysis shows that China’s designated hospital system for PLWHA has developed gradually with the characteristics of periodic and temporary changes. Conclusion:The designated hospital system for PLWHA in China has played an important role, but there are still several problems. The government should improve the existing system by strengthening the comprehensive medical service capacity of designated hospitals, improving the mechanism of consultation and referrals, coordinating the non-designated hospitals to provide technical support, reducing dis-crimination and fear from medical staff against HIV/AIDS, decreasing the risk of occupational exposure, and enhan-cing the communication among hospitals, CDCs and patients.

Objective To revise the trait self-control scale for Chinese college students.Methods According to the theory,12 items were selected,then data were collected from a sample of 549 and 133 college students of Harbin.Explorer Factor Analysis,Confirmatory Factor Analysis,reliability test and validity test were used.Results ①Trait self-control scale for college students included eight items,two dimensions were restrained and impulsivity,two dimensions can explain 42.90％ of the total variance.②Confirmatory Factor Analysis showed that the two-dimensional structure was reasonable (x2/df =1.24,CFI =0.97,GFI =0.96,AGFI =0.92,IFI =0.97,TLI =0.96,RMSEA =0.04).③The restrained factor scores were positively correlated with satisfaction of life scores and adaption scores(r=0.23,0.48,P＜0.01),while negatively correlated with negative affect (r=-0.19,P ＜0.01).The impulsivity factor scores were negatively correlated with satisfaction of life scores and adaption scores (r=-0.18,-0.34,P＜0.01),while positively correlated with negative affect(r=0.22,P＜0.01).④The composite reliability coefficients of the scales were good:the coefficient of the subscale restraint was 0.69,and the coefficient of subscale of impulsivity was 0.64,the coefficient of the whole scale was 0.80.The two months test-retest reliability coefficient of 133 subjects was 0.66.Conclusion The revised scale of trait self-control scale has good psychometric quality and can be used in Chinese college students.

Objective To evaluate the role of 5-hydroxy trptarine 2A receptor (5-HT2A) in the pathogenesis of biliary fibrosis after liver transplantation in rats.Method Rats were randomly divided into control group Ⅰ and control group Ⅱ[(supplied livers were preserved for 1 or 12 h),ketanserin group (recipients of control group Ⅱ were intraperitoneally injected with ketanserin 24 h postoperatively at the dosage of 5 mg · kg-1 · day-1),and sham group (rats were subjected to transverse laparotomy and closure without manipulation of the liver).During 4-week observation period,serum biliary enzymes,5-HT content in the liver,the expression of fibrosis-related genes,cholangiocytes proliferation and biliary fibrosis were evaluated.Result Compared with the sham group,the serum ALP,GGT,TBil and 5-HT contents in the liver homogenate were increased on the postoperative day 1 (POD1) and then restored to the normal level.There was slight proliferation of bile duct epithelial cells on POD3 in the control group Ⅰ,with fewer collagen fibers and α-sooth muscle actin (α-SMA)-positive myofibroblasts in the portal area.The expression of matrix metalloproteinase-2 (MMP-2) and procollagen α1-mRNA in graft livers was not significantly increased in the control group Ⅰ.To the contrast,the control group Ⅱ demonstrated high levels of serotonin in the liver homogenate and enhanced serum biliary enzymes.Active cholangiocytes proliferation was triggered on POD3 and remained higher than in the control group Ⅰ and the sham group.The control group Ⅱ showed a large number of α-SMA-positive myofibroblasts and collegan fibers at the postoperative week 4.In parallel,the major profibrogenic transcripts MMP2 and procollagen α1 were significantly increased at 2nd,and 4th week postoperation in the control group Ⅱ.Importantly,we also found that ketanserin relieved the signs of biliary fibrosis at 4th week postoperation in 5-HT2A group by the demonstration of reduced collagen fibers and a-SMA-positive myofibroblast in the portal area,as well as the decrease in the fibrosis-related gene expression.In addition to the lower cholangiocytes proliferation,serum levels of biliary enzymes including GGT,ALP and TBil in 5-HT2A group were significantly decreased at 4th week postoperation as compared with the control group Ⅱ.Conclusion Selective 5-HT2A receptor antagonist,Ketanserin retards biliary fibrosis progression posttransplantation,suggesting that 5-HT2A receptor is a potential therapeutic target for ischemia-related biliary fibrosis after DCD liver transplantation.
