Objective To reveal the role of PDK1 in vascular endothelial cells. Methods PDK1 was knocked out in endothelial cells by recombinase-mediated Cre to observe it′s effects on vascular endothelial cells. Results Abnormality of vascular development in rats could be found as a result of endothelial PDK1 deletion. Meanwhile, vascular leakage and bleeding phenotype were observed, and tissue analysis showed vascular endothelial cells abnormalities. Conclusions PDK1 plays an important role in the functioning and integrity of vascular endothelial cells, which made tentative explanation for PDK1-Akt signal path and laid basis for further research.

Objective To verify the dynamic changes of ANP during the diastolic heart failure and the protective effect of amlodipine. Methods Male SD rats underwent the abdominal aorta ligation. Four weeks after Surgery, 40 rats were divided into 4 groups: hypertension model group (group B), low-dose group (group C), mid-dose group (group D), high-dose group (group E). Another 10 healthy male SD rats were used as sham group (group A). During the experiment, different drugs were gavaged to different groups and the normal saline was used for control group. Results After 12 weeks, ANP levels increased in group B much more than in group A, while lower in group C(P < 0.05); LVSP and dp/dt max decreased in group B significantly than in group A, while higher in group C than in group B (P < 0.05); LVEDP and -dp/dt max had no statistically significant (P >0.05); HW/BW and LW/BW decreased in group B than in group A, while higher in group C than in group B (P < 0.05); The extent of myocardial necrosis and fibrosis in group C were much lower than in group B. But there was no Significant differences (P > 0.05). Conclusion ANP level gradually increased accompanying with the aggravation of heart failure, which is related with the dose of the drug within limits. Amlodipine can inhibit cardiomyocyte remodeling by interfering ANP secretion.

Objective:To investigate the mechanism of liver and lung injury in mouse septic models.Methods:Twenty-four male Kunming mice were subjected to cecal ligation and puncture(CLP)or sham operation.The permeability of microvasculature,water contents,activities of myeloperoxidase(MPO)and the apoptosis of microvascular endothelial cells in lung microvasculature and liver sinus were examined 3 h and 12 h after operation.Results:Both the liver and lung showed a significant increase in microvessel permeability at 12 h in CLP group compared with sham operation group.MPO activity and water content in CLP group were obviously higher than those in the sham operation group.The apoptosis of lung microvascular endothelial cells at 12 h in CLP group(5.03?0.92)% was significantly higher than that of control group(3.48?1.21)%(P

Objective To investigate the causes of severe H1N1 Flu with multiple organ dysfunction, and measures to reduce mortality. Method The data of the patient, who was diagnosed as severe H1N1 Flu and mul-tiple organ dysfunction syndrome in First People's Hospital Affiliated to Shanghai Jiaotong University in September 2009, were retrospectively analyzed. The patient was male, 35 year-old, obese, high fever, sore throat, cough, progressive dyspnea, severe hypoxemia and hypotension. Effective measures were carried out, including protective lung ventilation, recruitment maneuver, vasopressor support, limited fluid resuscitation, appropriate corticosteroid, anfiviral plasma, anticoagulafion and antiviral medicine (Oseltamivir)in early stage and full dose. Results After one-month intensive care, clinical symptoms was improved obviously, oxygen pressure reached 74 mmHg without oxygen supply, CT scan showed diffused interstitial ehange. Neuromyopathy developed at approximately 3 weeks after the onset of H1N1. Conclusions H1N1 Flu can develop in healthy adults, and obesity is one of the inde-pendent risk factors. Effective measures should be taken as soon as possible to reduce the mortality.

Ultrastructure of CA3 cell in hippocampus was observed with transmission electron microscope.Results After administration of YinlingⅠ,the lead content in blood, brain and bone decreased remarkably, the ability of learning and memory increased,and the ultrastructure changes of CA3 cell in hippocampus markedly dimi- nished.Conclutions YinlingⅠ may expel lead of the mice with lead poisoning and improve their ability of learning and memory.

There were significant increase in urine protein excretion,raised malondialdehyde(MDA) level and expressions of NF-?B,p22phox and p47phox in renal tissue,and significant decrease in reduced glutathione,superoxide dismutase,vitamin C and E levels in type 2 diabetic Goto-Kakisaki rats after 12 weeks. There was obvious histomorphologic change in the kidneys.All the above indices were improved by intraperitoneal injection of?-lipoic acid(35 mg/kg q.o.d).Besides,significant positive correlations were found of MDA level to p22phox,p47phox and NF-?B in the renal tissue,?-lipoic acid seems to protect the diabetic kidney in this diabetic rat model via antioxidative effects.

Objective:To collect the clinical materials of primary liver cancer patients treated by gamma knife and analyze the treatment methods as well as short-term efficacy,and to provide a reference for the clinical treatment of primary liver cancer patients.Methods:A total of 633 patients with inoperable primary liver cancer were treated by body gamma knife.According to the TNM staging method of Union for International Cancer Control(UICC), there were 351 cases with clear TNM staging.Among them, there were 251 cases (71.5%) at T3 stage and 57 cases(16.2%) at T4 stage.The prescription dose of 200-600 cGy each time to the 40%-85% dose line covering the planned target volume(PTV), this program was performed 5 times per week, and the number of treatment ranged from 2 to 13.The biochemical and imaging changes were observed 2-3 months after treatment to evaluate the short-term efficacy.Results:During the treatment, 229(36.2%)patients had adverse reactions,100 (15.8%) patients appeared the reduced white blood cells, and 137 (21.6%) patients appeared the reduced platelets.On discharge from the hospital, 601 patients were improved, 22 patients had no obvious change, 5 cases were worse, and 5 cases died.The proportion of improved patients who received the cumulative dose between 3 000 cGy to 4 000 cGy was higher than those who received the cumulative dose less than 3 000 cGy(P<0.05).After treatment, the curative effects were evaluated in 45 patients during two and three months, including PR 77.8%(35/45) and SD 22.2%(10/45), and the total effective rate was 77.8%(35/45).No statistical differences in effective rates were found between different tumor diameter, single dose, and cumulative dose groups(P>0.05).Conclusion:The proportion of adverse reactions in the primary liver cancer patients treated with body gamma knife is relatively low and the short-term efficacy is ideal.Body gamma knife treatment is a safe and effective treatment method for the primary liver cancer patients.
