Objective To investigate the expression of FHIT gene in the 60Co gamma-ray irradiated human lymphocytoblast(AHH-1) cell and the bystander effect cell,and to explore the function of FHIT gene in the bystander effect of ionizing radiation.Method Preparation of bystander effect cell model:after irradiated with different dose of 60Co gamma-ray(0,2,5 Gy),the directly irradiated AHH-1 ceils were collected immediately by centfifugation and co-cultivated with non-irradiated cells in Transwell.forming the bystander effect group P1.In addition,some culture media supernatant of direcfly irradiated cells were transfefred to the non- irradiated cells culture medium,forming the group P2.Then cells were collected at 0,6,12,and 24 h after irradiation and the total RNA and protein were extracted.RT-PcR and Western blot were performed to determine the FHIT mRNA and protein level.respectively.Flow cytometry assay and cell counting were conducted to detect the alteration of cell cycle and cell proliferation,respectively at 0,24 h after irradiation.Results The mRNA level of FHIT gene among control cells,directly irradiated cells and bystander cells showed no obvious difference. while the FHIT protein level of the directly irradiated ceils and bystander cells was siguificandy down-regulated compared with the control cells(F=102.45,P<0.001).Moreover,the directly irradiated cells and bystander cells showed significant G2 phase arrest and obviously inhibited the proliferation ability.Conclusions 2 and 5 Gy of 60Co γ-ray irradiated AHH-1 cells can result in down regulation of the FHIT protein expression,which suggests that FHIT gene is involved in the process of bvstander effect induced by irradiation.

Objective　To study the significance of alteration of concentration of endothelins(ET) and calcitonin gene related protein(CGRP) in bile in patients with acute choiangitis of severe type(ACST). Methods　The concentration of ET and CGRP were detected by radioimmunoassay in 55 cases of ACST at openation time, and 7th, 14th day after operation. Results　Compared with the control group, the concentration of ET in bile in patients with ACST was significantly higher at operation time(P<0.01～0.001). The concentration of ET in bile also showed significant difference at operation time between the 2 groups with different ACST severity(P<0.05). The concentration of ET in bile gradually reduced after operations. Compared with the control group, the concentration of CGRP in bile was signficantly lower at operation time(P<0.01). CGRP in bile gradually rose after operation. Conclusions　The ET in bile has some effect on the ACST pathologic alterations. The content of ET in bile is related to the severity of ACST. The disturbance of the balance between bile ET and CGRP may contribute to the pathologic process of liver and bile duct injury in ACST.

Objective To build experimental animal model of cerebral alveolar echinococcosis disease of sheep,in order to study of human alveolar hydatid disease of the brain.Methods Experiment animal models of ten Xinjiang big-tail sheep were performed by, direct skull puncture,intracerebral inoculation of echinococcus multilocularis.MRI was used to observe the growth status of cerebral alveolar echinococcosis disease of sheep after 8 months,and morphological and pathological characteristics after autopsy were ana-lysed.Results 4 sheep models (40%)were successful built which were confirmed by pathology and MRI.On MRI,4 cases all were single lesion,on T2 WI there was multiple follicles bubbles under the background of low signal in one case,and low signal in other three cases.Under the microscope,a large number of lymphocytes,eosinophils and plasma cells infiltrated the lesion area,around which small blood vessels were blocked and had inflammatory reaction were showed.Conclusion The method using artificial inocula-tion rat alveolar echinococcosis to establish experimental model of cerebral alveolar echinococcosis disease of sheep has the character-istic of feasibility,simplicity and repeatability.

Background and purpose: Diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) can be used for magnetic resonance imaging systemic examination, especially in examing the metastatic lesions, lymph node and bone diseases, and the imaging result is similar with PET. This study aimed to evaluate the application value of magnetic resonance DWIBS and positron emission tomography with computed tomography (PET/CT) on malignant metastatic diseases. Methods: Thirty-six patients confirmed with malignant tumors accompanying metastasis by the pathology of operation or biopsy underwent both DWIBS imaging and PET/CT, chi-square test and Kappa test were used for comparing the detection results of metastasis by these 2 imaging methods. Results:Among the 36 malignant tumor patients with 238 metastatic lesions, 218 (91.6%, 218/238) lesions in DWIBS and 209 (87.8%, 209/238) lesions in PET/CT were detected, with 200 lesions detected by the two methods simultaneously, and the concordance rate was 88.7%(211/238);but there was no statistical signiifcance between this two methods (χ2=1.843, P=0.157). Kappa test showed a fair concordance rate between DWIBS and PET/CT (P=0.000).There were different significance between DWIBS and PET/CT in detecting metastatic lesions of brain and bone (P=0.005 and 0.031);But there was no signiifcant differences (P=0.309 and 1.000) in detecting metastatic lesions of lymph nodes and liver. Conclusion:DWIBS could detect metastatic lesions effectively, and there is ifne consistency with PET/CT. DWIBS is more sensitive than PET/CT in detecting metastatic lesions of brain and bone, so DWIBS could be chosed for screening metastatic lesions according to the characteristics of different primary tumors.

OBJECTIVETo explore the effects of arecoline on hepatic insulin resistance in type 2 diabetes rats and to elucidate its possible mechanism.

METHODSForty five Wistar rats were fed with high fructose diet for 12 weeks to induce type 2 diabetic rat model. rats were randomly divided into 5 groups (n = 8): control group, model group and model group were treated with different dose (0, 0.5, 1, 5 mg/kg) of arecoline. After 4 weeks, the fasting blood glucose, blood lipid and insulin level measured , mRNA expression of liver constitutive androstane receptor (CAR), pregnane X receptor (PXR), glucose-6-phosphatase (G6Pase), phosphoenolpyruvate carboxykinase (PEPCK), interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were detected by reverse transcription polymerase chain reaction (RT-PCR), the protein expression of p-AKT and glucose transporter4 (GLUT4) were detected by Western blot.

RESULTS1.5 mg/kg arecoline could significantly decrease the level of fasting blood glucose, blood lipid, blood insulin level and liver G6Pase, PEPCK, IL-6, TNF-alpha mRNA level in type 2 diabetes rats. 1.5 mg/kg arecoline also could significantly increase CAR, PXR mRNA level and p-AKT and GLUT4 protein expression.

CONCLUSIONArecoline improved hepatic insulin resistance in type 2 diabetes rats by increasing the mRNA levels of CAR and PXR leading to the creased glucose metabolism and inflammation related genes expression.
