To observe the effect of oxidized low density lipoprotein (OxLDL) on arterial endothelial cells apoptosis in vivo, we established a model in which Sprague-Dawley rats were given intraperitoneal and intravenous injection of unmodified LDL (8 mg/kg every day) via the tail vein. Seven days after the injection, the aortic endothelial cells specimens were prepared by an en face preparation of rat aorta. The apoptotic cells were identified and counted by in situ nick and labelling (TUNEL) method and light microscopy. The numbers of the apoptotic cells were 12.52 +/- 4.71/field in the intraperitoneal injection control group, 11.41 +/- 2.94/field in the intravenous injection control group, 22.98 +/- 8.01/field in the intraperitoneal injection LDL group and 103.8 +/- 11.5/field in the intravenous injection LDL group, respectively. The difference was significant between injection LDL group and control (P < 0.01), and the difference was also significant between two LDL injection groups (P < 0.01). These findings suggest that injection of LDL can induce apoptosis in arterial endothelial cells and the effect is especially significant with intravenous injection LDL. After injection, oxidative modification of LDL may occur in local arteries and causes injury to the endothelial cells.

Objective To observe the curative effect about heavy abdomen type of anaphylactoid pur-pura treated by Methylprednisolone associate with Heparin. Methods Randomly divided eighty three children with heavy abdomen type of anaphylactoid purpura who treated in department of pediatrics of the first hospital affiliated to Kunming medical college from January, 2006 to december, 2007 into group A (treated by Hydro-cortisone) and group B (treated by Methylprednisolone) and group C(treated by Methylprednisolone associate with Heparin). Group A treated by mainline Hydrocortisone dose of 5~8 mg/kg body weight once a day,mixed into 100ml 5% glucose injection, after 7~14 days later, instead of take orally Predisone tablet and de-grees dose by gradually. Group B treated by mainline Methylprednisolone dose of 2~4 mg/kg body weight once a day, mixed into 100ml 5% glucose injection, after 7~14 days later, instead of take orally Predisone tablet, and group C treated by Methylprednisolone by oneself (dose like group B) associate with mainline Hep-arin (dose of 0.25~0.75 mg/kg body weight once a day, mixed into 100ml 5% glucose injection) 7~10 days. Observe clinic symptomatic like as tetter, bellyache, entron hemorrhage when treatment of every group. Contrast reiteration rate of anaphylaetoid purpura, and the period of urine test get hack normal which cases with kidney tamper. Contrast these medication' s side effect such as resort of natrium and water, elec-trolyte turbulence, hemorrhage and so on. Results Group C (treated by Methylprednisolone associate with Heparin) is better then group A (treated by Hydrocortisone) and group B (treated by Methylprednisolone by oneself) in eliminate tetrer and release bellyache. The less period of group C need to treatment entron hemor-rhage and urine test get hack normal. And thereiteration rate is less of group C than group A and group B.Conclusion Methylprednisolone in association with Heparin to treat heavy abdomen type of anaphylactoid purpura is better than hydrocortisone and Methylprednisolone by oneself in controling symptom, reduing reiter-ation rate and more less side effect. So methylprednisolone in association with Heparin to treat of heavy ab-domen type of anaphylactoid purpura is a ideal project.

Objectives To evaluate the influence of cardio-pulmonary bypass (CPB) to the endothelial function and lipid oxidative status of the Coronary Artery Bypass Grafting (CABG) patients. Methods Thirty-five coronary patients (female 5 cases, male 30 cases, mean age 59.5±8. 6 years) who needed CABG operation therapy were included. The control group consisted of 20 health volunteers (female 5 cases, male 15 cases, mean age 49. 5 ± 7.3 years).Blood samples were taken at preoperative, 3 and 7 days postoperative. Serum von Willebrand factor (vWF) level, one of the endothelial dysfunction markers,and oxidized low density lipid (OxLDL) level, one of the lipid oxidization status markers were detected with ELISA kits. Results The levels of vWF and OxLDL in CABG patients' serum were elevated significantly compared with those of control group ( 139.60% ± 34. 39% vs 82. 79% ±13. 89% and 63. 7 ±18. 9U/ml vs 25.4± 15.2U/ml respectively). Three and 7 days after CABG significant increases in the vWF level (194. 30% ±37. 74%; 181.07% ±31.05%vs 139.60% ±34.39% at baseline, P<0. 0001, respectively) and OxLDL level (79. 3±26. 7U/ml; 72.4±23.1U/ml vs 63.7±18. 9U/ml at baseline, P<0. 01, respectively) were detected. Conclusion Compared with normal people, the endothelial system of CABG patients is impaired, and their lipids are in a more oxidative status. CABG procedure with CPB can further deteriorate the conditions, which may imply that the patients are predisposed to acute coronary accident shortly are the procedure.

Objective To analyse the detection rates and antibiotic resistance of extended-spectrum β-lactamases (ESBLs) producing Klebsiella pneumonia and Escherichia coli in Intensive Care Unit (ICU) and to guide the clinical administration of treatment Methods Klebsiella pneumonia and Escherichia coli collected from clinical samples from January 2008 to December 2010 were tested by Phenotypic Confirmatory Test and confirmed by the method advised by NCCLs and drug-sensitivity was tested with K-B. Results Among the isolated 90 samples,49 strains were considered ESBLs-producing bacteria (54.4%) .with 52. 5% (31/59)of Klebsiella pneumonia and 58. 1% (18/31) of Escherichia coli respectively; with the specimens of respiratory system having the highest rate of 75. 5% (37/49). ESBLs producing bacteria were highly resistant to penicillins and cephalosporins, multi drug resistant to aminoglycosides and quinolones; low to piperacillin/tazobactam,cefoperazone/sulbactam,cefoxitin and amikacin; and all sensitive to imipenem. When compared to non-ESBLs producing strains, the rates of antibiotic resistance of the producing ESBLs strains were significantly higher. Conclusion The test results showed that the isolation rates of ESBLs-producing Klebsiella pneumoniae and Escherichia coli in ICU were high,which had high resistance to most antimicrobial agents,and the resistance was multiple. Imipenem could be the best choice to control the infection due to ESBLs-producing organisms. Timely detection of ESBLs producing bacteria and drug resistance is essential to guide clinical antibiotic using in ICU.

Aim To investigate the changes in the expression of protein kinase C gamma (PKC?), phosphorylated cAMP response element binding protein(pCREB)and immediate-early gene(c-fos and c-jun) in the spinal cord in formalin-induced inflammatory pain and study the effect of agmatine on the changes of PKC? activation, phosphorylation of CREB and expression of c-fos and c-jun.Methods Rats were decapitated at 10, 20 min or 2 h after intraplantar injection of 50 ?l 5% formalin and L_4, 5 spinal cords were dissected. Immunohistochemistry and western blotting analyses were used to observe the expression of PKC?, pCREB, c-fos and c-jun in the spinal dorsal horn and the effect of agmatine on the changes of their expression. Results Unilateral peripheral inflammation induced PKC? activation and CREB phosphorylation bilaterally while c-fos and c-jun expression ipsilaterally in rat spinal cord. PKC activity increased in membrane fractions with unchanged levels in the cytosolic fractions. Pretreatment intraperitoneally with 160 mg?kg-1 agmatine 15 min before inflammation significantly inhibited the activation of PKC? in the membrane fraction, suppressed the phosphorylation of CREB and the expression of c-fos and c-jun. Conclusion The mechanism of the analgesic effect of agmatine may be associated with inhibiting PKC? activation in the plasma membrane, CREB phosphorylation, c-fos and c-jun up-regulation which play roles in the hyperalgesia with peripheral inflammation.
