Objective To observe the therapeutic effect and adverse effect for chemthrombocytopenic of rhIL-11 in chemotherapy for acute myeloid leukemia. Methods We adopted a randomized, blank-control, crossover trial of rhIL-11 in 16 newly diagnosed patients with acute myeloid leukemia. The treatment group were accepted chemotherapy by DA or TA. rhIL-11 (25μg·kg-1·d-1, subcutaneously) was administered from 24 h after chemotherapy and continued for seven to fourteen days. The changes of platelet counts were observed. Results The group by chemotherapy had higher platelet counts than control after rhIL-11 treatment and platelet transfusion frequency was reduced. The adverse effect of rhIL-11 was light, including fatigue, muscular soreness and low-grade fever. Conclusion rhIL-11 is safe and effective in reducing chemotherapy thrombocytopenia.

Objective To evaluate the role of intercellular gap junction in lung injury induced by hemorrhagic shock and resuscitation in rabbits. Methods Twenty-four healthy rabbits of both sexes weighing 1.5-2.2 kg were used in this study. The animals were anesthetized with iv 3% pentobarbital 30 mg/kg,tracheostomized and mechanically ventilated. Femoral artery was cannulated for MAP monitoring, blood-letting.Right external jugular vein was cannulated for fluid infusion. Hemorrhagic shock was induced according to the method described by Wiggers. MAP was maintained at 35-40 mm Hg for 60 min. The animals were then randomly divided into 2 groups (n = 12 each):traditional treatment group (group A) and octanol group (group B). Both groups received rapid iv infusion of lactated Ringer's solution (LR solution) 1.5 ml·kg-1 ·min-1 for 30 min (T3 ).In group B 99.5% octanol (a specific gap junction inhibitor) 5 mmol/kg was injected intraperitoneally (IP) in addition to iv LR solution infusion. Thirty minutes later the animals were resuscitated with infusion of the blood withdrawn and LR solution (the volume was equal to the volume of blood loss). Then LR solution was infused iv at 2.5 ml· kg-1 · h-1 for 150 min ( T4 ). Left ventricular systolic pressure (LVSP) and HR were recorded before blood letting (T1), immediately after successful establishment of the model (T2), and at T3 and T4. The mortality during resuscitation was calculated. The animals were killed at T4. Blood samples were taken from femoral artery for determination of the serum protein concentration. The lungs were removed. The left lower lobe was lavnged. The protein concentration in broncho-alveolar lavage fluid (BALF) was measured. Lung permeability index (LPI) was calculated (LPI = protein concentration in BALF protein concentration in serum). Na+-K+-ATPase and Ca2+-ATPase activities and W/D lung weight ratio were determined and microscopic examination was performed. Results HR was significantly lower at T3 and T4 and LVSP higher at T4 in group B than in group A. The pulmonary permeability index, W/D lung weight ratio and mortality were significantly lower and the activities of Ns+-K+-ATPase and Ca2+ -ATPase were significantly higher in group B than in group A. The lung tissue danage was significantly ameliorated in group B. Conclusion Intercellular gap junction is involved in the development of lung injury induced by hemorrhagic shock and resuscitation in rabbits.

Objective To introduce the strategy of perioperative blood glucose control and the early outcome in diabetic and non-diabetic patients undergone coronary artery bypass grafting (CABG). Methods A total of 1019 CABG were performed and the patients were divided into diabetic and non-diabetic groups (n=211, 808, respectively). The demography was comparable between the two groups with the exception that the percentage of preoperative myocardial infarction was significantly higher in diabetic group than that in non-diabetic group. Off-pump and conventional CABG were routinely performed and the left internal mammary artery (IMA) and great saphenous vein (GSV) were used as conduit. Perioperative blood glucose was controlled according to the close supervision. The aim of preoperative 6mmol/L and postoperative 8mmol/L was achieved by means of oral medication or subcutaneous injection of insulin, which was complimented by continuous pump infusion of regular insulin to optimize the glucose level. Results 99.2% patients were discharged. The overall perioperative mortality was 0.8% and the percentage was 1.4% and 0.6% respectively in diabetic and non-diabetic group with significant difference(P0.05), respectively. Cerebral infarction occurred in 1.4% diabetic patients and in 0.5% non-diabetic patients(P

Objective To explore the effect of glial cell line-derived neurotrophic factor(GDNF) on the expressing of calbindin D28K(CB) in substantia nigra(SN) of rat model of Parkinson's disease(PD) and the possible role of neural cell adhesion molecule(NCAM) in this course.Methods 36 rat models of PD were made,and divided into GDNF group,NCAM blocked group and control group(each group had 12 rats).Immunohistochemistry and Western blot method were used to detect the number of CB-positive cells and the expressed level of CB protein in SN of rats.Results The number of CB-positive cells(46.50?6.28) and the expressed level of CB protein(33770.60?6929.76) in SN of GDNF group were significantly higher than control group [(27.00?8.60),(18281.00?5266.78) respectively](all P0.05).Conclusions GDNF may protect the injured dopaminergic neurons through up regulating the expressing of CB,but NCAM is not involved in this mechanism.
