The syndrome of malignant migrating partial seizures in infancy (MMPSI) is one of the most severe epileptic encephalopathies of infancy onset.It has been firstly reported by Coppola in 1995.There have been approximately 80 cases reported worldwide by now,but there is no case reported in our country.The etiology for MMPSI is still unknown,the diagnosis is difficult,and conventional antiepileptic drugs have little efficacy.This paper reviews the possible causes,clinical characteristics,diagnosis and treatment of MMPSI.

AIM: To establish a simple and repeatable orthotopic animal model of the A549 cell line.METHODS: A549 cells in matrigel were inoculated into left lung or right flank of nude mouse. The growth pattern of A549 tumors and the chemotherapeutic efficacy of carboplatinum were studied. RESULTS: Tumors generated and dispersed widespreadly to contralateral lung. Tumors in lung were less susceptible to carboplatinum than those growing in flank. CONCLUSION: A simple and repeatable orthotopic animal model of the A549 cell line was presented, this allows researchers to evaluate novel compounds and new drugs for treatment of human lung cancer.KEY WORDS A549 cell line; orthotopic model; nude mice

Ghrelin is a small active peptide secreted by gastric fundus cell. As an endogenous ligand of growth hormone receptor,it helps to promote growth hormone secretion,increase food intake and participate in energy metabolism. Recently,studies have indicated that Ghrelin,together with other peripheral signals,participate in the regulation of glucose and lipid metabolism. Insulin resistance (IR) is an important pathophysiological basis of the development of type 2 diabetes mellitus (T2DM),while obesity is the common risk factor of both IR and T2DM. It has been confirmed that Ghrelin has a close and complex connection with obesity and T2DM. Further study about Ghrelin may open up a new way to the diagnosis and treatment of obesity and T2DM.

Objective: To establish the determination of imperatorin and isoimperatorin in Tongketing Capsule (Radix Angelicae Dahuricae, Pheretima, etc.) by HPLC. Methods: The determination was carried out by HPLC. The mobile phase was acetonitrile water (60∶40) and UV detection wavelength was set at 245nm . The flow rate was 1.0mL?min -1 . The column temperature was 40℃ . Results: There were the good linear relationship between the absorption area value and the concentration in the range of 65?g～325?g for imperatorin and in the range of 50?g～250?g for isoimperatorin, respectively. The average recoveries were 98.3% ( RSD = 1.73% ) and 98.7% ( RSD = 1.65% ), respectively. Conclusion: The method is simple, accurate and can be used to determine imperatorin and isoimperatorin in Tongketing Capsule.

OBJECTIVETo explore the distribution features of Chinese medical syndromes of rheumatoid arthritis (RA) by literature retrieval.

METHODSPertinent articles on treating RA by syndrome differentiation were retrieved from China National Knowledge Infrastructure Databases (CNKI), VIP Chinese Biomedical Journal Database, Guizhou Digital Library, and Duxiu Chinese Academic Periodicals full papers database from January 2000 to December 2011.

RESULTSA total of 33 documents were recruited covering 4 233 cases. Damp-heat blocking collaterals syndrome occupied the top in the occurrence frequency (20 times, 60.61%), followed by deficiency of Gan and Shen syndrome (18 times, 54.55%), intermingled phlegm and blood-stasis syndrome (17 times, 51.52%), wind-cold-damp impediment syndrome (15 times, 45.45%), cold-damp blocking collaterals syndrome (14 times, 42.42%), wind-damp-heat impediment and deficiency of qi and blood syndrome (10 times, 30.30%), and intermingled cold and heat syndrome (9 times, 27.27%). According to the case number of patients, it was sequenced as damp-heat blocking collaterals syndrome syndrome (768 cases, 18.14%), wind-damp-heat impediment syndrome(666 cases, 15.73%), wind-cold-damp impediment syndrome(584 cases, 13.80%), cold-damp blocking collaterals syndrome syndrome (517 cases, 12.21%), intermingled cold and heat syndrome (415 cases, 9.80%), intermingled phlegm and blood-stasis syndrome (364 cases, 8.60%), deficiency of Gan and Shen syndrome (235 cases, 5.55%),asthenia of healthy energy due to lingering arthralgia syndrome (223 cases, 5.27%). The case numbers of remaining syndromes did not exceed 5%.

CONCLUSIONDamp-heat blocking collaterals syndrome was the main syndrome in RA patients, followed by wind-cold-damp impediment syndrome,wind-damp-heat impediment syndrome,cold-damp blocking collaterals syndrome,intermingled phlegm and blood-stasis syndrome, and deficiency of Gan and Shen syndrome.

Radiotherapy is one of the most important treatment method for esophageal cancer. Cene expression profile of cancer cells may be one of key factors in determining the effectiveness of radiation therapy To provide guidance for individual therapy, research advances in gene expression involved in radiosensitivity of esophageal cancer are discussed from three aspects: radiation damage repair, cell cycle distribution and signal traneduetion.

Objective To investigate the microvessel density of stomach tumor and the relationship between the microvessel density and CT findings.Methods Conventional contrast-enhanced CT scans were performed in 64 patients with stomach tumor(OMNIPAQUE 100 ml,3.0 ml/s),the images at 45 s were gained.After operation,the specimens with partial normal stomach tissue were dealed with injecting the contrast medium through its feeding arteries(10 ml/100 g,within 30 min),then,the specimens underwent CT scan(delayed time 10 s and 20 s),the nets of blood vessel of the masses were reconstructed by post-processed.The density of masses was evaluated in comparison with the enhanced effect of masses before operation.The pathological examinations of specimens were done and the microvessel density of tumors were measured through immunohistochemical technique.The hemodynamic characteristics of tumors were analysed.Results In tumors,the highest density(D)increased with the tumor rank(beside dead band).The visive vessels of specimen were more than that on conventional contrast-enhanced CT,but the D/d(the highest density in the masses/the density in normal stomach tissue)was basically consistent.Conclusion For gastric carcinoma,the D/d ratio can reflect the microvessel density of the tumors on certainly and the hemodynamic characteristics of tumors.

S100 proteins are a group of Ca2+ binding proteins. The main type of S100 proteins in nervous system (NS) is S1000B produced by astroglia cells and Schwann's cells. Recently, there are many researchs in the world which focuses on S100B biological activity and its mechanism, and these studies suggest that S100B plays a significant role inneuron development, neurite outgrowth and synaptic plasticity. We make a brief review in the field of S1000B biological property, distribution, biological activity and mechanism in NS. KEY WORDS S100 protein; neuron; glia; neu-rotrophic factor PKC; [Ca2+],;LTP

Objective To evaluate the changes of some humoral immune indices of patients with hypersplenism treated by radiofrequency ablation (RFA). Methods Totally 33 patients met inclusion criteria were randomly assigned to receive RFA (17 patients) as trial group and splenectomy (16 patients) as control group. The level of serum immune globulin,complement and tumor necrosis factor (TNF) in venous blood was determined preoperatively and postoperative 1 week,1 month,and 6 months. We evaluated intergroup differences in immune function by comparing the indices. Results In the trial group,no significant differences were found in humoral immune indices between postoperative and preoperative values. Although the level of postoperative serum complement did not change significantly,serum IgM was lowered significantly (P0.05). Conclusion Because part of the spleen is remained in RFA,the humoral immune function is reserved better than that of splenectomy.
