Objective To observe the effect of nerve growth factor(NGF) on Caspase-3 expression in hippocampus of epileptic rats induced by kainic acid(KA) and explore the protective effect and mechanisms of NGF on the epileptic neurocytes.Methods Sixty healthy rats aged 21 to 30 days were randomly divided into 3 groups,each of which included 20 rats.Rats in group A were treated with 9 g?L-1 sodium,rats in group B were treated with KA,rats in group C were treated with KA and NGF.Concentration of KA was 2 g?L-1 diluted by 9 g?L-1 sodium;KA was injected into rats in group B and group C,intraperitoneally.Then state of seizure was recorded,and EEG and pathological section were performed.Five rats in each group were sacrificed by perfusion with paraform respectively at 6 hour,on the 1st day,on the 3rd day after injection of KA.Specimen was sampled and made into frozen section.Expression of Caspase-3 in hippocampus of epileptic rats was analyzed by immunohistochemistry.And microscope image measuring and analysis instrument was used to analyze image of expression.Results Symptoms of seizure appeared 30 min after injection of KA.Seizure was proved by detection of EEG and pathological section.Expressions of Caspase-3 detected by immunohistochemistry in group C decreased at every time spot were higher than those in group B,and the defferences between 2 groups had statistically significant(Pa

Purpose:To evaluate the effect of metallic stent in the treatment of malignant stricture in esophagus and cardia.Materials and Methods:Treated by metallic stent:14patients with malignant stricture in esophagus and cardia,13 males and 1 female aged ranged from 57 to 81,were discussed in this article.Among 12 patients,8 were proved as esophageal squamous carcinoma,4 as esophagus adenocarcinoma,and 1 was complicated with esophagotrachial fistula,l0 of the pa- tients could take fluid food and 4 only water.After catheterizing from mouth,the strictured portions dilated with hallon catheter,15 selfmade Z stents coveted with dacron and 1 strecker stent were in 13 and 1 patients respectively.Results:All stems were successfully placed.Patients could eat more easily after the operations.The esophogotrachial fistula was completely sealed.The average lifetime after the operation was 5.5 months.Conclusions:Metallic stent prosthesis is an effective method to treat malignant stricture in esophagus and cardia,and could elevate the life quality of patients sig- nifieantly.

Extranodal NK/T cell lymphoma is a kind of disease that is associated with EB virus infection and characterized by progressive distruction and necrosis of the nasal cavity and midline facial tissues, with histological features of diffuse lymphomatous cells inflitrate and inflammatory cells as abackground or angiocentric and angioinvasive inflitrate.The prognosis is poor,as it is highly aggressive and it can progress rapidly.This article mainly discusses and reviews the progress in treatment methods.

Objective To investigate the pattern of lymph node metastasis in patients with 17 and middle thoracic esophageal squamous cell carcinoma( ESCC). Methods Retrospective review the clinical data of 246 cases with T2 and middle thoracic esophageal squamous cell carcinoma who were treated by three-field lymphadenectomy. Analyze the relationship between clinical pathological factors and lymph node metastasis. Results Lymph node metastases were found in 129 of the 246 patients (52.4% ).The average number of resected lymph nodes was 25 per patient (rangel5 -59). The rates of lymph node metastasis were 28.9% in the neck, 28.5% in thoracic mediastinum and 22.0% in abdominal cavity for patients with T2 and middle thoracic ESCC. No significant difference in lymph node metastasis' rate was observed among the neck, thoracic mediastinum and abdominal cavity. Logistic-regression showed the length of tumor, tumor cell differentiation and angiolymphatic invasion were factors influencing lymph node metastasis. Conclusion Lymph node metastasis in T2 and middle thoracic ESCC has the characteristics of upward, downward and skip spreading. Patients with T2 and middle thoracic ESCC should be treated with radical surgery with three-field lymphadenectomy.

Objective To investigate the role of proteoglycan autoimmunity in the pathogenesis of rheumatoid arthritis (RA). Methods Human Aggrecan G1 domain cDNA was cloned from human cartilage, and recombinant aggrecan G1 domain (rAG1) protein was synthesized in a Baculovirus expression system. Synovial fluid monocytes from RA patients were stimulated with rAG1. Harvested cells' radioactivity was quantified in a ?-scentillation counter and the stimulation index (SI) was calculated. Cells with SI over 3 were taken as rAG1 specific T cells. Three well-characterized AG1-specific T cell lines were injected intraperitoneally into 8 SCID Beige mice. At the same time, rAG1 was injected intraarticularly into left knees of these mice. On day 8, mice were sacrificed and histological examination of the knee joints was performed. Results Human rAG1 specific T cell lines were generated from synovial fluid of RA patients. Most of these cells were CD4~+CD8~- T cells secreting Th1 cytokine (interferon-?). A pronounced capsular and synovial infiltration of mononuclear cells with early synovitis and cartilage erosion was observed in some left knees of the mice treated with rAG1-specific T cells. Conclusion Human rG1-autoreactive T cells injected intraperitoneally have homed to left knee where its epitope rAG1 was injected, and they participated in the development of inflammatory arthropathy.

Objective To investigate the long term efficacy and safety of thalidomide in the treatment of refractory ankylosing spondylitis.Methods A total of 232 patients with refractory ankylosing spondylitis were recruited into open study using thaiidomide at a dose of 150 mg/d, bath ankylosing spondylitis disease activity index ( BASDAI) , spinal pain score and thaiidomide related side effects were observed regularly.Results From the third month, BASDAI and spine pain score decreased significantly when compared with those of the base line ( P < 0.05).Such improvement became more obvious as time went on.A total of 148 patients (63.8% ) got >50% improvement in BASDAI and spine pain score, and 76 cases (32.8% ) reported absence of spine pain.The major side effects were drowsiness, constipation, dry mouth, dizziness and dandruff.Thirty two patients (13.8% ) withdrew from the study because of adverse events.Most of the adverse effects disappeared as thaiidomide was stopped.Conclusion Long term thaiidomide is effective and safe for treating resistant ankylosing spondylitis and it has cumulative effect as duration prolongs.

OBJECTIVETo establish a method for rapid determination of organic fluorides in the air of a fluorine chemical plant using portable gas chromatography-mass spectrometer (GC-MS).

METHODSStandard samples of monochlorodifluoromethane, tetrafluoroethylene, and hexafluoropropylene of different concentrations were prepared by static volumetric method with high-purity nitrogen as the diluent gas. The samples were injected into the GC-MS by a hand-held probe. Retention time and characteristic ion were used for qualitative analysis, and the area of selected ion peak was used for quantitative analysis. The standard curves were then created for quantitative determination of the three organic fluorides.

RESULTSThe linear ranges for monochlorodifluoromethane, tetrafluoroethylene, and hexafluoropropylene by the method were 0.39-7.72, 0.45-8.84, and 0.61-12.20 mg/m3, respectively, the average recovery rates for the three concentrations were 102.8%, 96.0%, and 106.5%, respectively, and the average deviations were 2.1%, 5.1%, and 2.4%, respectively.

CONCLUSIONThe portable GC-MS can be used for the simultaneous qualitative and quantitative analysis of monochlorodifluoromethane, tetrafluoroethylene, and hexafluoropropylene in the workplace air, and the method is simple, fast, and accurate.
