Multifunctional proteglycan, versican, is recently recognized as a gene related to tumor metastasis. Versican may maintain or inhibit cell growth, affect cell adherence and regulate the mutual interaction between cells or cell and matrix. Higher expression of versican always correlates with worse prognosis.

Objective To observe the effect of prostaglandin E1 on soluble interleukin-6 receptor(SIL-6R) and soluble interleukin-6 receptor β strands (sgp 130) in serum in patients with chronic severe hepatitis.Methods Sixteen patients with chronic severe hepatitis accepted therapy with prostaglandin E1.Serum levels of SIL-6R and sgp130 were detected by enzyme linked immunosorbent assay (ELISA) method before and after therapy.Results The content of SIL-6R and sgp 130 in serum were increased significantly (P<0.001) in patients with chronic severe hepatitis compared with normal control group and decreased obviously (P<0.01) after therapy with prostaglandin E1 compared with before therapy,and the rate of delth were decreased obviously (P<0.01) in PGE1 therapy group.Conclusion The levels of SIL-6R and sgp130 in serum can reflect the degree of liver damage in patients with chronic severe hepatitis and guide the assessment of prognosis;PGE1 can correct the immune disorder,attenuating hepatocyte inflammation and necrosis.

Objective Using transcranial Doppler (TCD) to evaluate the effect of selective shunt (SS) during carotid endarterectomy (CEA). Methods TCD was used for intraoperative bilateral middle cerebral artery (MCA) cerebral blood flow continuous monitoring in 169 patients with carotid stenosis treated with CEA. The patients were divided into shunt (n =32)and non-shunt (n = 137) groups according to whether they performed shunt or not. The open approaches of anterior collateral circulation were recorded. The peak systolic velocity (PSV),mean velocity (MV), pulsatility index (PI), and ratio of MV in bilateral MCA were compared after anesthesia, before and after carotid artery occlusion, before and after shunt, and after carotid artery open. Results MV before carotid artery occlusion in the shunt and non-shunt groups were 34.73 ± 13.54 cm/sand 35.32 ± 13.18 cm/s, respectively, and there was no significant difference (P = 0. 825). MV in the shunt group after carotid artery occlusion was significantly decreased in the non-shunt group (P =0. 000). The mean decline rate of MCA MV was 69.34% ± 20. 93%, and it was decreased more significantly than that in the non-shunt group (P=0. 000). The decline rate of MCA MV was increased significantly after shunt operation, the average increase was 35.68 ± 16.69 cm/s (P=0. 000). Conclusions TCD can objectively evaluate the hemodynamic changes before and after shunt operation.

Objective To observe the effect of electroacupuncture at Baihui (GV20) and Shenting (GV24) on learning-memory function and ultrastructure in hippocampal CA1 region of rats after cerebral ischmeia-reperfusion. Methods A total of 25 male Sprague-Dawley rats were randomly divided into sham group (n=6) and operation group (n=19). The operation group was occluded the left middle cerebral arter-ies with modified Longa's methods for 90 minutes and reperfused, and twelve qualified rats of them were randomly divided into model group (n=6) and electroacupuncture group (n=6), the later accepted electroacupuncture at Baihui and Shenting for seven days. They were as-sessed with Longa's scores, and tested with Barnes maze. Their cerebral infarct volume was tested with magnetic resonance imaging T2-weighted image. The ultrastructure of synapse in hippocampal CA1 region was observed with transmission electron microscope. Results Compared with the model group, the Longa's score improved (P<0.05), the infarct volume decreased (P<0.01), the average escape latency decreased (P<0.01) and the times entering the wrong hole decreased (P<0.001) in the electroacupuncture group. Under the transmission elec-tron microscope, the number of synapse decreased in the model group, with the structure damage and vesicles sparse;compared with the model group, the number of synapse increased in the electroacupuncture group, with clear and complete structure and rich vesicles. Conclu-sion Electroacupuncture at Baihui and Shenting can improve the learning-memory function in rats after cerebral ischmeia-reperfusion, which may relate to improvement of synaptic plasticity and ameliorating ultrastructure in hippocampal CA1 region.

Objective: To study clinical application value of dobutamine stress echocardiography (DSE) and nitroglycerin stress single photon emission computed tomography (SPECT) for evaluation of restenosis after percutaneous coronary intervention (PCI). Methods: A total of 39 patients after PCI were examined by DSE and SPECT one week before coronary angiography (CAG). Dose incremental program of dobutamine included five levels：5μg•kg-1•min-1, 10μg• kg-1• min-1, 20μg•kg-1•min-1, 30μg•kg-1•min-1, 40μg•kg-1•min-1, and each level maintained for three minutes. Sensitivity, specificity and accuracy of DSE and SPECT were determined according to CAG examined result and examined results were compared between DSE and SPECT. Results: Compared with CAG, SPECT and DSE were no significant differences （P>0.05）in sensitivity (83.3% vs. 75.0%) and accuracy (71.8% vs. 87.2%) for evaluating restenosis after PCI, but compared with SPECT, DSE possessed higher specificity (66.7% vs. 92.6%). Conclusions: Dobutamine stress echocardiography is accurate, and its specificity is better than that of SPECT for evaluating restenosis after percutaneous coronary intervention.
