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 summarize the herbal medication in treating malignant ascites based on literature. Methods TCM literatures concerning malignant ascites from CNKI (1989.1-2013.3) were retrieved. The herbs and those category, nature, flavor and meridian distribution were summarized by frequency method. The couple herbs were analyzed by hierarchical cluster analysis. Results Fifty-five qualified documents and 56 effective prescriptions were collected. A total of 164 herbs were used (668 frequencies). Six groups of herbs, cumulative relative frequency (CRF) of 61.83%, were used frequently in order as follows:the herbs for promoting diuresis and resolving dampness, invigorating qi, invigorating the blood and removing blood stasis, regulating qi, eliminating heat and toxin, excreting drastically water. The most frequently used herbs (>6 frequencies, CRF 53.74%) had 25 species. The first three places were the herbs for promoting diuresis and resolving dampness (5 species), invigorating qi (4 species), invigorating the blood and removing blood stasis (3 species). These herbs were mostly of warm nature (260 frequencies, 38.92%). The total frequency of herb-nature was 1055 and the sweet (354 frequencies, 33.55%), bitter (284 frequencies, 26.92%) and pungent (268 frequencies, 25.40%) herbs were used more frequently. The total frequency of meridian distribution was 1747 and these herbs were mostly attributed to spleen, lung, liver, and kidney meridians (>200 frequencies). The most frequently used couple-herbs included Poria and Rhizoma Atractylodis Macrocephalae, Radix Astragali and Ramulus Cinnamomi, etc. Conclusion Invigorating qi was emphasized in treating malignant ascites, combined with promoting diuresis. The herbs of the warm and cold nature, the sweet, bitter and pungent flavor, spleen, lung, liver and kidney meridians were most frequently used.

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.

Professor Wei Pin-kang developed phlegm theory for gastric cancer. He adopted the therapy of resolving phlegm and dispersing nodules as the fundamental therapy for gastric cancer. As the symptoms may vary due to the changes of etiology and pathogenesis at different stages of gastric cancer, he further formulated eight therapies based on the fundamental therapy, namely, resolving phlegm and regulating stomach, resolving phlegm and removing stagnancy, resolving phlegm and clearing heat toxin, resolving phlegm and relieving qi depression, resolving phlegm and dredging collaterals, resolving phlegm and removing blood stasis, resolving phlegm and promoting diuresis, and resolving phlegm to soften abdominal mass. These therapies showed satisfactory effects following the principle of simultaneous treatment of disease and symptoms.

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.
