Asparaginase(ASP) is an important drug in the treatment of childhood acute lymphoblastic leukemia and non-Hodgkin lymphoma.Asparaginase associated pancreatitis (AAP) is the main treatment-adverse events of asparaginase.After reviewing the recent foreign literatures about AAP and the Chinese expert about polyethylene glycol conjugated asparaginase (PEG-ASP) in the treatment of acute lymphoblastic leukemia and malignant lymphoma with asparaginase,conclude and analysis the data about childhood AAP and show the epidemiology,clinical features,early diagnosis and effective treatment of children with AAP.Make clinical compare of L-asparaginase and PEG-ASP.Based on the full grasp of the relevant data,analyzing,introducing and integrating,this may be helpful to the diagnosis and treatment of childhood AAP.

Since upper limb function disorder exists in many children with cerebral palsy, it is improtant to assess and treat the disorder of the upper extremities. The common assessments include muscle tone, range of motion and upper extremity assessment. The goal of therapy is to decrease the muscle tone and increase the range of motion. In addition we should emphasize the functional ability and purposeful skill of the upper extremity.

Gene therapy of spinal cord injury (SCI) is the most promising method compared with the others, because it doesn't involve the problems of resource and higher exclusion which respectively exists in fetal nerve transplantation and peripheral nerve transplantation. There are two ways of gene therapy to be chosen: one is to transfer objective genes to the target-cells in vivo directly; the other is to transfer objective genes to one proper kind of transplantable cells firstly, then graft the highest expressing cells to the target-cells in vivo. To realize the transfer of genes to cells, two measures are used in common: physical or chemical measure such as micro infection et al and biochemical measure i. e. gene modified defective virus. Although there are some questions unresolved in this field, the clinical value of gene therapy of SCI in the future is depended.

Free-DNA exists in body fluid of cancer patients, and the concentration is much higher than that of healthy people, and the free DNA is characteristic of tumor issue. This article makes a summary about the study of free DNA in cancer patients,such as methylation,gene mutation, microsatellite instability (MSI) and loss of heterozygosity( LOH ). It has important significance for tumor dignosis,assessment of prognosis and recurrence.

Experimental incised wounds 8 mm in diameter were made on the right side of the back of 48 rats under anesthesia using aseptic technique. All animals were randomly divided into 12 groups according to the time of wound biopsies which were taken immediately after skin cutting, lh,12h,24h,2,3,4,5,6,7,8,9 and 10 days after wounding.One rat of each group was given colchicine before animal sacrifice in order to observe cell mitosis. Skin specimens were fixed in 10% formalin,embeded in paraffin and sectioned for HE stain,Gorden and Sweet stain for reticular fiber,Weigert stain for elastic fiber,PTAH stain for fibrin and Van Gieson stain.Macroscopically, wounds were getting smaller daily,and reduced in size markedly on the 6～7th day. The histologic changes were as follows:Acute inflammation on the wall of wounds occurred 1h after skin cutting;profuse fibrin exudation at the top of the base and on the wall of wounds at 24h;new capillary formation and regeneration of the epidermis on the 2nd day;granulation tissue formation and collagen fiber deposition on the 3rd day;small artery formation in the granulation tissue on the 4～5th day;granulation tissue maturation and the regenerating tissue covering the whole wound area on thd 6～7th day;the scar formation and contraction on the 8～9th day;further sear contration on the 10th day.The epidermis regenerated from the proliferation of the epidermis at the edge of the wound with the speed of 1.23mm/day. The regeneration of the epithelium proceeded under the necrotic tissue on both the wall and at the base of wounds. The mechanism of the wound contraction was discussed.

Various studies have suggested that adrcnergic activtaion may contribute to deleterious effects on myocardial ischemia. However, very little is known about it s role during reperfusion. This study was designed to explore the relationship between endogenous norepinephrine (NE) and reperfusion injury in intact rabbits. In rabbits(n=5) 35 min of coronary occlusion without reperfusion thc myocardial NE content of the ischemic area was not significantly different from that of the non-ischemic area, nor was tissue calcium content in both areas, while, in 35 min of occlusion followed by 10 min of reperfusion group(n=5), the tissue NE was markedly reduced in reperfused area accompanying significant calcium overloading. These studies suggest that the postischemic reperfusion injury may be, in part, due to endogenous catecholamine release during reperfusion.

Objective To retrospectively analyze the risk factors of recurrent groin hernia. Methods Data came from all hernia repairs recorded in our hospital between 1991 and 2001. A total of 1 082 cases of groin hernia was analyzed through Cox proportional hazard model to determine the relative risks between recurrence and mode of admission, types of groin hernia, repair methods (traditional/tension free hernioplasty), and post operative complications.Results From 1991 to 2001,1 082 groin hernia operations were performed in our hospital, 88.9% for primary hernia and 11.2% for recurrent hernia. As compared with traditional hernia repair methods, Lichtenstein’s tension free hernioplasty technique had less relative risk for recurrent hernia repair than that for primary hernia repair. Postoperative complications and indirect hernia were linked to an increased relative risk for recurrence. Conclusion There are many factors affecting the recurrence of inguinal hernia, but the use of tension free hernia repair may decrease re recurrence of recurrent hernia.

Objective To investigate the role of the imbalance of Th 1/Th 2 cells in the pathogenesis of autoimmune thyroid diseases (AITD). Methods Thirteen patients with Graves′ disease (GD), 12 patients with Hashimoto′s thyroiditis (HT) were recruited for the study, and 8 patients with non-toxic nodular goiter served as controls. The expressions of interferon-? (IFN-?) and interleukin-4 (IL-4) of intrathyroidal mononuclear cells (ITMC), representative cytokines of Th 1 and Th 2 cells respectively, were assayed by immunohistochemical technique. Thyroid stimulating antibody (TSAb), thyroglobulin antibody (TGAb) and thyroid microsome antibody (TMAb) in peripheral blood were detected by routine methods, and their correlations with the IFN-? and IL-4 were analyzed. Results (1) Compared with the controls, the IL-4 and IFN-? expressions of ITMC in GD and HT patients were remarkably increased (both P

Objective To investigate the protective effect of gynostemma on myocardium and its mechanism in patients with diabetes associated with hyperlipemia.Methods 178 patients with type 2 diabetes mellitus with hyperlipidemia from the department of endocrinology in our hospital were selected and divided into two groups, 89 cases in the control group treated with basic treatment of diabetes+atorvastatin, 89 cases in the experiment group received gynostemma on the basis of the control group, myocardial injury index, blood glucose level, blood lipid level, serum cytokine levels and serum oxidative stress response indexes were detected and compared after the treatment.Results Compared with the control group, serum levels of aspartate aminotransferase(AST), creatine kinase(CK), CK-MB, lactate dehydrogenase(LDH)were lower in the experiment group after treatment, fasting plasma glucose(FPG), 2h postprandial blood glucose(2hPG), HbA1c level were lower after treatment, serum levels of total cholesterol(TC), triglycerides( TG ) , low-density lipoprotein cholesterol ( LDL-C ) were lower, high-density lipoprotein cholesterol ( HDL-C ) level was higher after treatment, serum level of adiponectin(ADPN) was higher, tumor necrosis factor-alpha(TNF-α), interleukin-6(IL-6), interleukin-18(IL-18) levels were lower after treatment, serum levels of malondialdehyde(MDA), reactive oxygen species(ROS) were lower, glutathione peroxidase(GSH-Px), superoxide dismutase(SOD) levels were higher after treatment, with significant difference (P<0.05).Conclusion Gynostemma can significantly reduce the cardiac muscle damage of patients with diabetes associated with hyperlipemia , plays a role in myocardial protection, the mechanism may be to reduce blood glucose and blood lipid levels, inhibit the inflammatory reaction caused by inflammatory cytokines, improve the antioxidant capacity of the body and reduce oxidative stress damage.
