Objective To discuss the relationship between plasma levels of tissue factor(TF) in the circulation and the development of smooth muscle cells(SMC) hyperplasia after percutaneous coronary intervention(PCI) in porcine models.Methods Thirty swines were used and their coronary arteries were injured by balloon dilatation.Morphological measurements included neointimal area and the extent of area stenosis.Plasma TF level was measured before and after PCI.The relationship between TF and neointimal area was calculated.Results Different degrees of intimal hyperplasia were found among all vessels and the rate of restenosis was 60%.Plasma TF levels were significant higher in vessels which subsequently developed restenosis(30 minutes after PCI: 688.36?91.57 ng/L vs 514.87?68.73 ng/L,24 hours after PCI: 706.09?89.59 ng/L vs 539.22?70.51 ng/L,P

Intensity-modulated radiation therapy (IMRT)is a more advanced radiotherapy technique than routine radiotherapy,and has been effectively utilized in the treatment of nasopharyngeal carcinoma (NPC).Rradiotherapy alone has disappointing effect to local advanced cases.Nevertheless,chemoradiotherapy provides long term survival.Chemoradiotherapy is becoming the standard therapeutic regimen for local advanced NPC.But different ways of chemomdiotherapy such as induction,concurrent,adjuvant chemotherapy still need to be defined.

Objective To find out the relationship between fetal growth restriction (FGR) and transforming growth factor -β1 (TGF-β1). Methods The levels of TGF-β1 in maternal serum and placental tissue of FGR were detected with using ELISA and immunohistochemistry technique, and it was compared with those of normal term pregnancy. Results The levels of TGF-β1 in maternal serum of FGR group were significantly higher than those of normal term pregnancy (76. 5 ± 33. 4 VS 47.6 ± 24. 2, t' = 4. 65, P ＜0. 05). As for the intensity of the immunohistochemistry signal, TGF-β1 in syncytiotrophoblastic cells of FGR was markedly higher than that of control group (81.82% vs 5.83%, P ＜0. 01). Conclusions The levels of TGF-β1 are closely related with FGR.

Objective To study the effects of ephedrine and phenylepbedrine for maintenance of arterial pressure during combined spinai/epidural anesthesia (CSEA) for caesarean section. Methods Forty patients, ASA grade Ⅰ - Ⅱ, who were scheduled for caesarean section by CSEA were randomly divided into two groups, when patients were hypotension, phenylephedrine 100 μg (group P, 20 cases ) or ephedrine 10 mg (group E, 20 cases). The variety of blood pressure (Bp), heart rate (HR) and oxyhemoglobin saturation (SpO2) were monitored; recorded before anesthesia (T0), at 15 min after anesthesia (T1), fetuses were taken out of uterus (T2) and at the end of operation (T3); umbilical arterial blood gas analysis was monitored; neonatal Apgar score was investigated. Results Umbilical arterial blood gas analysis of pH,PaO2, PaCO2, HCO3-, SaO2 were normal in two groups, there were no significant difference in PaO2, PaCO2 and SaO2 between two groups, but pH and HCO3- in group P were higher than those in group E [7.38±0.07 vs7.30±0.02 and (21.5±3.4) mmol/L vs (19.3±3.3) mmol/L] (P <0.05). There were no significant difference in Apgar score and Bp between two groups. Compared with group P, the HR in group E was increased obviously at T1 and T2 (P < 0.05). Conclusion Phenylephedrine is the vasopresser that most closely meets the criteria for the best vasopressor to use in obstetric patients.

In order to advance the public hospital reform, the performance tests and management were strengthened to promote the rapid development of the hospital. The status of average daily bed ocupation, the number of outpatients and the natural birth rate increased while the drug proportion declined. Some departments were the top level in Hebei, departments of gynaecology and pediatrics were in the leading level in Tangshan.

Objective To investigate the possibility that transplanting the full-thickness neonatal piggy retinas that are completely differentiated but immature improves the retinal function after light-induced retinal degeneration in pigs.Methods Retinas from normal Guangxi Bama pigs aged 1-6 days were used as donor tissues.Neuroretina-RPE cografts were obtained from newborn pigs by using excimer laser for microablation of choroidal tissue and transplanted into the subretinal cavity of adult Bama pigs after light-induced retinal degeneration through vitrectomy and retinotomy.On days 5-7 and in 1st to 5th month after retinal transplantation,the survival of the cografts in the recipients and whether the host retinas have rejection were observed by ophthalmoscope,colour fundus photography and fundus fluorescein angiography,and the amplitude and lantency of N1,P1 waves between different periods were measured by mfERG.Results The retinal transplantation was performed in 15 eyes of 8 Bama pigs after light-induced retinal degeneration.The subretinal transplantation of the cografts was performed successfully in 11 eyes,with the operation success rate of 84.6%(11/15).In host retina,the gray-black graft inside transplantation bed could be seen clearly in 1st to 2nd month after transplantation and the leaked fluorescence in transplants was checked with FFA.The vertical comparison between different periods showed the amplitude of N1,P1 waves of retinal transplants rose with the extension of the survival time,and the areas where active response was observed were ring 2 and ring 3;but the latency of N1,P1 waves was shortened significantly in each ring as compared with that before operation,especially in late survival period.Conclusion The function measurement and the observation of living body together confirm the transplantation of completely differentiated retina from newborn pigs improves the retinal function of pigs after light-induced retinal degeneration.

Objective To establish a model of injury to primarily cultured spinal cord neurons,mimicking the neuronal injury after complete transactional spinal cord trauma,for the sake of exploring changes in expression of an immediately-early gene,c-jun,in central nervous system injury. Methods Spinal cords were removed form fetal Wistar rats at the 14th gestation day and the neurons were cultured for 10 to 12 days.Then,mechanical injury was applied to the neurons by making regular scores on the culture disk under direct vision with the aid of a self-made standard template.Morphology of the injured neurons and changes in expression of c-Jun protein were observed before and at different intervals after injury. Results c-Jun expression was noted in neuronal nuclei 10 min after injury and its peak appeared at 2 hrs.Besides,the density of positive neurons bore evidently an inverse proportion with their distance from the scores.Conclusion\ Positive expression in injury neurons show that c-jun gene enters the nucleoli of injured neurons and takes the role of “the third messenger” at early time after neuronal injury.

0.05)。The median time to progression (mTTP)was 5.8 months in XELOX group and 5.7 months in FOLFOX4 group. The median survival time (MST) was 10.0 months in XELOX group and 9.8 months in FOLFOX4 group, The toxicities were well tolerated,The incidence of grade Ⅲ+Ⅳ nausea and vomiting was significantly lower in XELOX group than in FOLFOX4 group (P0.05).Conclusions:Both of the two regimens were feasible, well tolerated and effective in treatment of advanced gastric cancer。XELOX regimen may be safer than FOLFOX4 regimen,especially in elderly patients or patients with ECOG PS of 1 to 2.
