Background and purpose:A pre-surgery diagnosis of cervical invasion in endometrial cancer was usually determined by dilatations and curettage(D&C),so it could help in optimizing surgery,but the reliability of D&C still was controversial.This study was to compare MRI with D&C to estimate their accuracy for the diagnosis of cervical invasion in endometrial carcinoma respectively.Methods:34 endometrial cancer patients had been proved to have cervical invasion in endometrial cancer through examinations of either fractional dilatations and curettages(D&C),magnetic resonance imaging(MRI)before surgery or postoperative histopathologic examination.The results of D&C and MRI were compared with postoperative histopathologic examination,and the sensitivity,specificity were estimated for accuracy of cervical involvement in endometrial cancer.Results:21 of 34 patients were identified as having cervical invasion in endometrial cancer by histopathology after operation.D&C test matches 26.5% of them and MRI test matches 80%.The sensitivity was 35% vs.76.5% and the specificity 7.7% vs.100% for D&C and MRI methods respectively.All of them had significant statistical differences.Conclusions:MRI test is much better than D&C method for preoperative diagnosis of cervical invasion in endometrial carcinoma.

Objective To investigate the protective effects of continuous norepinephrine infusion and its mechanism in early stage of lipopolysaccharide induced septic rats.Methods Forty SD rats were randomly divided into 5 groups (an external jugular vein catheterization was performed in every rat a day before intraperitoneal injection):saline control group (n =8),endotoxin group (n =8),low dose norepinephrine therepy group(n =8),middle dose norepinephrine therepy group (n =8),and high dose norepinephrine therepy group (n =8).Saline control group received intraperitoneal injection of 0.9％ saline 10 ml/kg,and then received an infusion of 0.9％ saline 1 ml/h.Endotoxin group animals were intraperitoneal injected with lipopolysaccharide 10 mg/kg,and then received an infusion of 0.9％ saline 1 ml/h.Therapy group animals received an infusion of norepinephrine solution 1 ml/h after being intraperitoneal injected LPS 10 mg/kg.The doses of norepinephrine were 0.06,0.3,0.6 μg/(kg· min) respectively.Blood samples were taken 2 h and 6 h later and the levels of serum TNF-α、IL-1β and IL-10 were detected by enzyme-linked immunoadsorbent assay.The membrane potential and three tricarboxylic acid cycle key enzyme activity [isocitrate dehydrogenase(IDH) and pyruvate dehydrogenase (PDH) activity] of isolated liver mitochondrion were detected 24 h later,and the morphologic changes of mitochondria in liver were observed by electronic microscopy.Results In endotoxin group,the levels of serum TNF-α JL-1 β and IL-10 all increased significantly(P ＜ 0.05) and liver mitochondrial membrane potential,PDH and IDH activity decreased significantly compared with control group(P ＜0.05,P ＜0.01).In the middle dose of norepinephrine therepy group,the levels of serum TNF-α and IL-1β all increased significantly (P ＜ 0.05,P ＜ 0.01),the level of serum IL-10 decreased significantly compared with endotoxin group (P ＜ 0.05) ; In the high dose norepinephrine therepy group,the liver mitochondrial membrane potential,PDH and IDH activity increased significantly compared with endotoxin group (P ＜ 0.05).The mitochondrial ultrastructural changes in every group were not obviously.Conclusion In the early stage of septic rats,reversible liver mitochondrion injury can be observed.Norepinephrine infusion can protect early septic rats through attenuating inflammatory reaction and enhancing tricarboxylic acid cycle key enzyme activity and mitochondrial membrane potential level.

Objective To evaluate the correlation between the expression of C5b-9 and the gastric carcinoma.Methods In this study, the human gastric adenocarcinoma (HGAC)tissues (n =32 cases)from 32 patients were evaluated by immunohistochemistry and tissue chip.The result was analyzed and evaluated by Multinomial logistic regression and likelihood ratio.Results Multinomial logistic regression and likelihood ratio testing showed that over-expression of C5b-9 in HGAC tissue was significantly correlated with clinical stage (P =0.007) and tumor stage (P =0.005),but not with tumor metastasis,lymphoid nodal status,sex or age.Conclusion C5b-9 can be the criteria of di-agnosis and clinical staging for gastric adenocarcinoma,which may help in diagnosis and assessment disease severity of human gastric carcinoma.

Objective To investigate the impact of high altitude on human gastric mucosa and its underlying mechanisms. Methods Twenty-five native Tibetans with chronic mountain sickness CMS residing at high altitude (4500 m) were examined for ultrastrueture and pathological changes of gastric mucosa. The other 25 native Tibetans residing at low altitude (＜2000 m) were served as control.The expression of hypoxia-inducible factor (HIF)-1α in human gastric mucosa was detected with immunohistochemistry. Results The color of gastric mucosa presented dark in patients with CMS.The histopathological examination showed significant differecnce in incidence of cnronc body gastritis and atrophic gastritis between CMS group and control group (P＜0. 05). The transmission electronic microscopy revealed that the epithlieal cells of gastric mucosa were impared in CMS group compared to control group. The expression of HIF-1α protein was increased in CMS group in comparison of control group (102.94± 34.04 vs 14.04 ± 6.53, P＜0.05). Conclusions The high altitude may involve in damage of gastric mucosa and the up-regulation of HIF-1α protein may involve in its mechanism.

The human bone morphogenetic protein 7 (hBMP 7) gene was reconstructed in retroviral vector and transferred into incasing cells PT67 by liposome mediated method.The clones of the cells transferred with BMP 7 were selected by G418, and targeted rabbit bone marrow stem cells were infected with the virus granules which secreted from PT67 cells and also selected by G418. The mRNA and protein of BMP 7 gene in transferred cells were analyzed with hybridization in situ and immunohistochemistry. BMP 7 retrovirus vetor was successfully reconstructed. Cells transferred by PLNCX 2 hBMP 7 expressed abundant human BMP 7 mRNA and protein in the cytoplasm. However positive findings were not found in those cells that were not transferred. It may be used to increase the osteogenic capability of BMSc in the study of bone tissue engineering.

Objective To explore the value of time-resolved angiography with interleaved stochastic trajectories (TWIST)in providing hemodynamic indices and morphological imaging of calf arteries in patients with peripheral arterial occlusive disease(PAOD) with 3.0 T MR scanner. Methods Forty patients with confirmed or suspected PAOD underwent TWIST MRA for the calf arteries and conventional contrast-enhanced MRA(CE-MRA) for the whole lower peripheral arteries. TWIST MRA data were used to determine the bolus arriving time of the popliteal artery, the time difference of the bolus arrival in the popliteal artery between the two legs, calf artery transit time, and the mean peak enhancement time of calf arteries. The mean value of peak enhancement time of calf arteries was correlated with ankle-brachial index(ABI). The calf arteries were divided into 13 segments. The visible score of arterial segment was recorded, and the degree of arterial stenosis was graded too. In 16 patients, DSA was used as the gold standard to evaluate the sensitivity and specificity of TWIST MRA and CE-MRA. Results The bolus arriving time of the popliteal artery was (0.7±7.6) s the time difference of the bolus arrival in the popliteal artery between the two legs was (2.1±2.5) s, the calf artery transit time was (35.6±16.9) s, the mean value of peak enhancement time of calf arteries was (52.6±17.6) s. ABI was acquired from 24 patients and 48 legs, which correlated well with the mean value of peak enhancement time in calf arteries (r＝0.627,P＜0.01). The mean visible score was (2.83±0.48) of TWIST MRA images and (2.78±0.43) of CE-MRA images. There was no significant difference between them (P＞0.05). On CE-MRA, there were 38 legs with varying degrees of early venous enhancement; in contrast, there was no venous contamination on TWIST MRA. The sensitivity and specificity of TWIST MRA were 96.7% (118/122) and 100.0% (72/72) in showing normal artery and mild stenosis, 94.1% (32/34) and 96.2% (154/160) in showing severe stenosis, and 94.7% (36/38) and 98.7% (154/156) in showing occlusion. The sensitivity and specificity of CE-MRA were 95.9% (117/122) and 100.0% (72/72) in showing normal artery and mild stenosis, 91.2% (31/34) and 95.6% (153/160) in showing severe stenosis, and 94.7% (36/38) and 98.1% (153/156) in showing occlusion. Conclusion TWIST MRA is a preferable choice for calf arterial occlusive disease, which provided nice morphological images and useful hemodynamic indices with simple operation.

AIM　To study the effects of dexamethasone on expressing monocyte chemoattractant protein-1(MCP-1 ) mRNA in the rats with pulmonary fibrosis, elaborate the molecular mechanism of dexamethasone (Dxs) in pulmonary fibrosis therapy. METHODS　The model of pulmonary fibrosis was established by instilling bleomycin intratracheally. After treating with Dxsip, the levels of MCP-1 mRNA were determined by RT-PCR. The histological changes were observed and the numbers of inflammatory cells were counted in optical microscopy field. RESULTS　The accumulation of inflammatory cells decreased markedly, and the symptom of pulmonary fibrosis was alleviated. Furthermore, Dxs evidently inhibited the expression of MCP-1 mRNA in lung tissues with pulmonary fibrosis. CONCLUSION　The molecular mechanism of Dxs in pulmonary fibrosis therapy was associated with inhibiting the expression of MCP-1 mRNA.
