Objective To find the inpact(s) of Losartan on myocardial apoptosis in rats with heart failure. Methods Eight-week-old male SD rats were divided into control group(group C),heart failure(group HF) and treatment group(group LS). Use of doxorubicin injection model,group LS at the same time in a row to the oral losartan,myocardial ultrastructure was examined by TEM. DNA-situ terminal labeling (TUNEL method) was used to detect myocardial apoptosis and myocardial BAX,BCL-2 protein expression was detected by immunohistochemistry.ResultsGroup HF showed significant myocardial cell injury,and apoptotic bodies were found,serum CPK,CK-MB and LDH were increased. In LS group,myocardial apoptosis index was lower (P

Objective To find the inpact(s) of Losartan on myocardial apoptosis in rats with heart failure. Methods Eight-week-old male SD rats were divided into control group (group C) , heart failure (group HF) and treatment group (group LS). Use of doxorubicin injection model, group LS at the same time in a row to the oral losartan, myocardial ultrastructure was examined by TEM. DNA-situ terminal labeling (TUNEL method) was used to detect myocardial apoptosis and myocardial BAX, BCL-2 protein expression was detected by immunohistochemistry. Results Group HF showed significant myocardial cell injury, and apoptotic bodies were found, serum CPK, CK-MB and LDH were increased. In LS group, myocardial apoptosis index was lower (P <0. 01) , myocardial cells BCL-2 expression, BAX expression reduced as compared with those in HF group. Conclusion Losartan can effectively inhibit the process of heart failure occurred in cardiomyocyte apoptosis, reverse myocardial damage and improve the prognosis of heart failure.

Objective To study the diagnostic value of detecting pre-albumin,albumin and protein electrophoresis in the serum of patients with fever of unknown origin.Methods Serum pre-albumin,albumin and protein electrophoresis were detected in 86 patients with fever of unknown origin and 26 controls.Results The level of albumin and pre-albumin in fever of unknown origin group was lower than that of control group(P

Objective To investigate the expression of nicotinic acetylcholine receptor (nAchR) subunits, and the effects of smoking on its expression in peripheral blood mononuclear cells (PBMCs). Methods Blood was collected from 92 healthy male smokers and 36 healthy male non-smokers. Peripheral blood monocytic cells were obtained, and reverse transcription-polymerase chain reaction (RT-PCR) was employed to study the gene expression of 11 nAchR subunits (?2-?7, ?9, ?10, ?2-?4). Results The results showed that the PBMCs of smokers and non-smokers appeared to express ?2, ?5, ?6 and ?7 only out of 11 nAchR subunits. However, the expression of ?5 and ?7 subunits was lower in smokers′ PBMCs than in non-smokers′ (P

By using cup culture, influence of different strains (ammonium-resistant N2-fixing type, wild type, none N2-fixing type) of Klebsiella oxytoca on the growth of rice seedling was compared. It was discovered that ammonium-resistant N2 -fixing bacteria could excrete some plant growth promoting substance, which could be adsorbed by cation resin. It' s activity wouldn't be affected at 80℃. At optimal concentration, the weight of rice root and seedling were increased by

Based on the physiological properties of ammonium-resistant N2-fixingbacterium ( Klebsiella oxytoca NG13/pMC73A), the fermentation technology of it was studied. The basic medium of high-density culture was established, with glucose as carbon source coupled with appropriate nitrogen source and inorganic salts. At the middle and late phase of culture, glucose and ammonia were added to supply carbon source and nitrogen source, stabilizing the pHat 6.5 ~ 6.8. Optimal level of dissolved oxygen was kept by controlling aeration and stirring rate. Bacterium number of Klebsiella oxytoca NG13/pMC73A reached 600 ~ 700 x 10s cfu/mL at the end of culture. Compared with previous technology, bacterium number was increased by more than ten-fold with a comparable culture period.

Objective To investigate the clinical value of serum Haptoglobin (Hp)levels in cervical cancer patients.Methods Serum Hp (with immunoturbidimetry method),SCC,CA125 (with electrochemiluminescence immunoassay method)level were detected in 45 patients with cervical cancer,37patients with cervical benign disease and 41 female healthy controls.Re-sults Serum Hp level of cervical cancer patients (mean:1.69 g/L)was strongly higher than the level of cervical benign dis-ease patients (mean:0.90g/L)and healthy subjects (mean:0.69 g/L)(t=3.26,4.42,P=0.001,0.000,respectively).Hp level rises highly in the early stage of cervical cancer.The area under receiver operating characteristic curve (AUCROC)of Hp was 0.853 which was higher than SCC (AUC=0.751)and CA125 (AUC=0.494).The sensitivity of Hp,SCC,and CA125 were 87%,49% and 29% respectively.The specificity of Hp,SCC and CA125 were 68%,88% and 83% respective-ly.Three tumor markers combined together could produce a positive detection rate of 93%.Conclusion The detection of Hp has clinic significance on diagnosis of cervical cancer,and it’s possible to become a serum tumor marker.

0.05).There was a positive corrlation on CD40~+ and CD40L~+ in chronic B hepatitis patients.There was a positive corrlation on CD8~+/CD28~+ and CD40~+、CD40L~+ in chronic B hepatitis patients.There were no remarkable corrlation on CD8~+/CD28~- and CD40~+、CD40L~+ in chronic B hepatitis patients.Conclusion:The costimulation molecules CD40~+、CD40L~+ and CD8~+/CD28~+ are lower,while CD8~+/CD28~- are higher in chronic B hepatitis patients than in the health.To test the expression of CD40~+、CD40L~+ and CD8~+/CD28~+ on peripheral blood of the chronic B hepatitis could help to evaluate patients's celluar immunity and guide clinical treatment.
