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.

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.

Abstract: Based on years of ancient literature research and clinical experience, Professor Pin-kang Wei developed the phlegm theory of gastric cancer. In light of the properties of gastric cancer and the method of differentiating syndromes within the traditional Chinese medicine (TCM) paradigm, it is believed that gastric cancer is closely related with phlegm. Much ancient literature regarding the relationship between phlegm and gastric cancer was reviewed to explain the rationale and academic inheritance of the phlegm theory. In this theory, gastric cancer is regarded as a form of phlegm stagnation and consists of phlegm core, phlegm collateral and phlegm contamination. In order to explain the mechanism of development, recurrence and metastasis of gastric cancer, phlegm contamination is regarded as the most fundamental cause and pathogenesis of gastric cancer. The therapy of resolving phlegm and dispersing nodules is suggested for the fundamental treatment of gastric cancer.

Objective To explore effect of miR‐302a on proliferation and apoptosis in folate deficiency mouse embryonic stem cell (mESC) .Methods The cases were divided into complete culture medium group (control group) ,folate‐deficient culture medi‐um group (folate‐deficient group) ,folate‐deficient culture medium plus miR‐302a mimic group (miR‐302a group) .The expression of miR‐302a was examed by RT‐PCR in control group and folate‐deficient group .To construct miR‐302a mimic and then was trans‐fected into the folate‐deficient culture medium mESC .Effect of miR‐302a mimic on mESC viability was detected by MTT assay ,the effect of miR‐302a mimic on mESC apoptosis was examed by Annexin V‐FITC/PI flow dual‐staining method ,the effect of miR‐302a mimic on mESC cycle was examed by flow cytometry .The activation of phosphatidylinositol 3 kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) and expression of CyclinD1 ,p21 and p27 was assayed by Western blot . Results The expression of miR‐302a was lower in folate‐deficient group(P<0 .01) .Compared with control group ,the viability of mESC was lower ,the apoptosis of mESC was higher ,the cell cycle was arrested in G1 phase ,the level of phosphorylation of AKT and mTOR was lower ,the expression of CyclinD1 was lower ,the expression of p21 and p27 was higher in folate‐deficient group , with statistical significance (P<0 .01) .Compared with folate‐deficient group ,the viability of mESC was higher ,the apoptosis of mESC was lower ,G1 phase was shortened ,the level of phosphorylation of AKT and mTOR was higher ,the expression of CyclinD1 was higher ,the expression of p21 and p27 was lower in miR‐302a group with statistical significance (P<0 .01) .Conclusion These results suggested miR‐302a exerted anti‐apoptosis and promote cell proliferation in folate‐deficient culture medium ,which might be related to PI3K/AKT/mTOR signal pathway .

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.
