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.

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

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 epidemiology and evaluate possible age-related differences in the presenting clinical features in three year-old children with Mycoplasma pneumoniae pneumonia(MPP)during 2009 to 2014.Methods The medical records of 17855 children with community-acquired pneumonia enrolled by Children′s Hospital of Soochow University during 2009 to 2014.Totally 1145 younger than three year-old children with MPP were enrolled,and they were classified into three groups of 1 month to 1 year-old group (n=512),1 to 2 year-old group (n=393) and 2 to 3 year-old group (n=240).The epidemiology and possible age-related differences in the presenting clinical features,main laboratory and imaging results in three year-old children with MPP were summarized.Results (1) The highest infection rate of different reasons in Suzhou was in autumn(10.46%),and the lowest was in spring(6.95%),The highest infection rate of different ages was 2 to 3 year-old group(11.61%),and the difference was statistically significant (P<0.05).(2) Compared with 1 month to 1 year-old group(n=512,4.31%) and 1 to 2 year-old group (n=39,10.09%),2 to 3 year-old group (n=240,11.61%) had higher infection rate,more patients with fever(53.9% vs. 77.1% vs. 85.4%) and high fever(16.8% vs. 30.5% vs. 41.4%),longer time to normalization of temperature(3d vs. 5d vs. 6d),but less patients with wheezing(61.3% vs. 52.4% vs. 42.9%) and dyspnea(7.6% vs. 4.6% vs. 3.8%).(3) The differences were statistically significant in the percentage of neutrophils,lymphocytes,CRP and platelet count between different ages(P<0.001).(4) The incidences of large area of lesions in chest X-ray examination among different ages had significant differences(P<0.001).Conclusions MP is one of the important pathogens of respiratory tract infection in younger than 3 year-old children.It can occur in every season,and the highest infection rate of MP is in autumn and spring.In younger than 3 year-old,older patients are more vulnerable to infection of MP,the number of fever and high fever are more,fever duration is longer,but younger patients are more vulnerable to virus infection and prone to dyspnea.Chest X-ray examination shows small patchy shadow in most cases,the younger children are more easily to have large area of lesions and pleural effusion.

Objective To explore the expression and significance of matrix metalloproteinases-9(MMP-9) and tissue inhibitors of matrix metalloproteinase-1(TIMP-1) in serum at acute phase of severe pneumonia in infants.Methods A total of 45 infants of pneumonia were selected and divided into 20 cases of severe pneumonia group and 25 cases of mild pneumonia group according to the severity of the disease,and all 45 infants were also divided into virus group of 24 cases and non-virus group of 21 cases on the basis of etiology.Additionally,20 cases of healthy children who accepted the physical examination at the same time were selected as the control group.Serum levels of MMP-9 and TIMP-1 were detected by using ELISA.Tidal breathing lung function was measured in all selected infants.Results Compared with the control group,the serum levels of MMP-9,TIMP-1 and MMP-9/TIMP-1 ratio of the infants with acute pneumonia were significantly higher,the severe pneumonia group were higher than the mild pneumonia group,and the virus group were higher than the non-virus group(P＜0.05).The ratio of the time to reach peak tidal expiratory flow to total expiratory time (TPTEF/TE) and the volume to reach peak tidal expiratory flow to total expiratory volume(VPTEF/VE) of pneumonia group in recovery period were significantly lower than those in the control group,severe pneumonia group were lower than those in the mild pneumonia group,and the virus group were lower than those in the non-virus group (all P＜0.05).There were no statistically significant about VT/kg among three groups.The serum MMP-9 levels and the MMP-9/TIMP-1 ratio were negatively correlated with TPTEF/TE and VPTEF/VE (r1=-0.459,-0.376; r2=-0.413,-0.327; all P＜0.05).Conclusion The serum levels of MMP-9 and the MMP-9/TIMP-1 ratio in the acute phase of infantile pneumonia are correlated with pneumonia severity and pulmonary function injury in recovery period,and the performance is particularly prominent in the viral pneumonia,and can be used as a prognosis monitoring indicator.

Aim To investigate and evaluate the effect of ligustrazine on the expression of scavenger receptor type AI, the human ?-interferon activation site (GAS) elements regulatory systems of SR-AI expression wasfirst established in the Xenopus oocytes. Methods A plasmid, in which the human SR-AI gene was constructed downstream from the GAS elements, was microinjected into the nucleus of Xenopus oocytes. The oocytes then were cultured in the smooth muscle cell conditioned medium (SCM), In which the cell were cultured with the treatment of oxLDL for 2 days. In the other groups, the oocytes were treated with SCM containing the nature medicines ligustrazine, and the positive control drug ?-interferon respectively. Results The results demonstrated that SCM could upregulate the expression of SR-AI in this system, this action was suppressed by ligustrazine and ?-interferon. Conclusion Similar to the action of ?-interferon, ligustrazine can prevent the over-expression of SR-A induced by oxLDL, via their effect on the GAS elements regulatory pathway.
