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

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.

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.

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.

Five genes that are closely related with leukemia were detected and identified using COREMINE Medi-cal, and the abstracts of related papers covered in PubMed were analyzed with the biomedical text mining tool, Chilibot, which showed that leukemia interacts with the 5 genes detected using COREMINE Medical.

Objective:To analyze the effect of endoscopic submucosal tunnel dissection on patients with large esophageal superficial neoplasms.Methods: Chosen patients with large esophageal superficial neoplasms in our hospital as research object, randomly divided into control group treated by endoscopic mucosal dissection (ESD) and observation group treated by endoscopic submucosal tunnel dissection(ESTD), compared surgery related indicators, complications and treatment outcomes.Results: 1)Observation group patients’ tumor stripping rate (23.17±4.73)/min was significantly higher than control group patients’ (12.65±2.19)/min; Intraoperative blood loss(9.14±0.67)ml, total length of hospital stay (7.34±1.89) d, were significantly less than control group patients with intraoperative blood loss(21.38±3.14)ml, total length of hospital stay (13.21±3.05)d, t value was 4.965, 5.395, 4.932, respectively(t=4.965,t=5.395,t=4.932;P<0.05); 2)Observation group patients esophageal bleeding ESTD rate(5.26%), esophageal stricture rate(31.58%), mediastinal emphysema rate(5.26%), esophageal perforation rate of 0, were significantly less than control group patients with esophageal bleeding rate(31.58%), esophageal stricture rate(5.26%), mediastinal emphysema rate(21.05%), esophageal perforation rate (26.32%), t value were 4.378, 4.378, 4.471, 5.758, (t=4.378,t=4.378,t=4.471,t=5.758;P<0.05); 3)Observation group patients with no recurrence during the follow-up period, control group patients with local recurrence rate of 21.05%, t value 8.623,P<0.05(t=8.623, P<0.05).Conclusion: Endoscopic tunnel mucosal stripping technique can effectively improve the complete tumor removal rate, during the process of optimization operation at the same time reduce the occurrence of complications, to the improvement of the prognosis of patients with positive clinical significance.

In order to better accommodate heterogeneous quality of service (QoS) in wireless networks, an algorithm called QeS-aware power and admission controls (QAPAC) is proposed. The system is modeled as u non- cooperative game where the users adjust their transmit powers to maximize the utility, thus restraining the interferences. By using adaptive utility functions and tunable pricing parameters according to QoS levels, this algorithm can well meet different QoS reqniremcnts and improve system capacity compared with those that ignore the QoS differ- ences.
