Objective To evaluate the effects of tadalafil on chronic allograft vasculopathy. Method The abdominal aorta transplantation was performed on Male Lewis or Brown-Norwai rats as donors and male Male Lewis rats as recipients. The recipients were divided into 3 groups: Group A (Lewis-Lewis)with no treatment ;Group B (BN-Lewis) with no treatment; Group C (BN-Lewis) received tadalafil treatment (0.5 mg/kg per day). The rats were sacrificed at 8 weeks post treatment. The grafted aortas were used for histology and Western blot assay. Plasma cGMP level was detected by ELISA assay. Results The aortas intimal in group C was significantly thinner than that in group B. PKG-Ⅰprotein expression in group C was significantly higher than that in group B. Expression of RhoA in group C was lower than that in group B. Conclusion Tadalafil has positive effect on chronic allograft vasculopathy.

Objective To study the effective hemostatic method for treating multiple trauma accompanied with hemorrhagic shock to increase the existence rate. Methods In treating 5 patients of multiple tauma accompanied with hemorrhagic shock, We used radiological embolism to injuried parenchymatous organs and injuried vessels to arrest the bleeding at first. After shock recovered, prompt exploration was made to repair injuried hollow viscus. Results After embolism and bleeding arrested, shocks in all 5 patients were corrected in short time; and no serious active hemorrhage was found after abdominal operation to repair the hollow viscus. All 5 patients survived after the operation. Conclusions The radiological embolism is simple,and has the little trauma and a good hemostatic effect,and needs short time. The method for treating multiple trauma can improve the salvage rate of multiple trauma accompanied with hemorrhagic shock and fit the treatment principle of multiple trauma.

OBJECTIVETo observe the role of magnesium sulfate in vascular calcification, to explore the role and the mechanism of magnesium sulfate in vascular calcification.

METHODSThe vascular calcification model was established by administration of vitamin D3 plus nicotine (VDN) in SD rats. To estimate the extent of calcification by Von Kossa staining, calcium content and alkaline phosphatase activity, osteopontin (OPN) mRNA were determined by using semi-quantitative reverse-transcription polymerase chain reaction.The malondialdehyde (MDA) and nitric oxide (NO) content and activities of superoxide dismutase(SOD) were measured by biochemistry.

RESULTSA strong positive staining of black/brown areas among the elastic fibers of the medial layer in calcified aorta by Von Kossa staining, calcium content and ALP activity in calcified arteries increased by 3.9-and 3.4-fold as compared with the controls. The expression of OPN mRNA was up-regulated by 40% (P < 0.01). The lipid peroxidation products MDA in vascular were increased 2.0-fold (P < 0.01). The NO content and SOD activity were greatly decreased by 64% and 72% (P < 0.01), respectively, compared with controls. However, calcium content and ALP activity in VDN plus magnesium sulfate group were lower than those in VDN group. Low and high dosage magnesium sulfate obviously relieved degree of calcification in the cardiovascular tissues in a dosage-dependent manner (P < 0.01).

CONCLUSIONMagnesium sulfate plays a role in the pathogenesis of vascular calcification by reducing vascular calcification and decreasing vascular injury.

OBJECTIVETo investigate two single nucleotide polymorphism sites of T cell immunoglobulin domain and mucin domain protein-4 (TIM4) and to detect their relationship with allergic asthma in a population of Hans from Hubei province of China.

METHODSThe polymorphisms (8570G > A and 11515C > A) were detected with polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 145 cases of allergic asthma and 130 healthy controls. The genotype and allele frequencies were calculated and analyzed.

RESULTSThe genotype frequencies of GG, GA and AA in 8570G > A polymorphism were 0.985, 0.015 and 0 respectively in the healthy population and 0.931, 0.069 and 0 respectively in the allergic asthma population. There was significant difference in genotype and allele frequencies between the allergic asthma patients and control subjects (P=0. 030, P=0.032). The polymorphism of 11515C>o A was not detected.

CONCLUSIONThe polymorphism of 8570G > A in TIM4 may be associated with allergic asthma in the population of Han nationality from Hubei province of China.

AIMTo observe the effect of angiotensin-converting enzyme inhibitors (ACEI) and aldosterone receptor blockers on cardiac function to explore the mechanism of cardiac function descending and myocardial injury in calcium-overload rats.

METHODSCalcium-overload in rat was induced by administration of Vitamin D3 plus nicotine. To Estimate the extent of calcium-overload by calcium content. Angiotension II and aldosterone levels in the myocardia were measured by radioimmunoassay. Cardiac function (+/- LVdp/dt, LVESP and LVEDP) were measured by Powerlab. The malondialdehyde (MDA) content, activities of lactate dehydrogenase (LDH) and creatine kinase (CPK) were measured by biochemistry.

RESULTSCalcium content increased by 3.2-, 5.8 -fold in myocardial and artery, compared with controls. VDN-treated survivors showed lower + LVdp/dt(max) and -LVdp/dt(max) values, by 27% and 34%, respectively (both P < 0.01). Higher LVESP, and LVEDP by 42 % and 32% (P < 0.01); heart rate and mean arterial pressure were not significantly altered (P > 0.05). The lipid peroxidation products MDA and conjugated diene in myocardia were increased 22% (P < 0.01), 68% (P < 0.05) (P < 0.05), respectively. The plasma activity of CPK and LDH was greatly increased by 4.5-and 3.1-fold (P < 0.01), respectively. ACEI and spironolactone obviously relieved degree of calcium-overload and improved cardiac function and myocardial injury(P < 0.01). Calcium content in myocardia and artery was lower 44%, 39% and 57%, 34%. Lower MDA by 20%, 30%, lower conjugated diene by 44%, 35% than calcium-overload group. The plasma activity of CPK and LDH were obviously decreased 28%, 34% and 20%, 27%, compared with calcium-overload group.

CONCLUSIONCalcium-overload could lead to cardiac function descending and myocardial injury in calcium-overload rats by VDN. ACEI and spironolactone could reduce calcium-overload in myocardial and ameliorate cardiac function and decrease myocardial injury.

We explored the effect of therapy with bacteriophages for pandrug resistant Acinetobacter baumannii infections.Kunming mice (Specific Pathogen Free) were divided into two groups:experimental group (severe infection caused by pandrug resistant Acinetobacter baumannii) and the control group.The mice of experimental group were treated with Phages AB46 while the mice of control group were treated with broth.The survival rate was compared with statistical method and the spleen bacteria count was analyzed.Results showed that there were statistical difference between the experimental group and control group of Pandrug resistant Acinetobacter baumannii groups of 1 ∶ 10 dilution,P=0.020＜0.05.There were no statistical difference between each two groups of 1 ∶ 2 (P=0.650) and 1 ∶ 5 (P=0.170) dilution,both were＞0.05.There were no dead mice in groups of 1 ∶ 50 dilution with statistical difference of spleen bacteria count,P=0.026.Therapy with phages was an ef fective method to control infection caused by Pandrug resistant Acinetobacter baumannii which could increase the survival rate and decrease spleen bacteria count of the mice with light infection.
