目的:探讨及研究组织因子(TF)分别在初发型和复发型翼状胬肉中的异常表达及临床意义。方法:分别用免疫组织化学方法对30例初发型和10例复发型翼状胬肉中TF表达情况检测,并与20例人正常的球结膜组织进行对照比较。结果:在翼状胬肉组织中,均可检测到TF表达。TF主要位于上皮细胞的胞质中,而在正常的球结膜组织里,TF则无表达或呈现弱阳性的表达。其中,在初发型翼状胬肉组织中阳性表达率为86.67%(26/30),而在复发型翼状胬肉组织中阳性表达率为90.00%(9/10),在正常的球结膜组织中阳性表达率为10.00%(2/20),三者相比较其差异具有统计学意义(P0.001)。结论:TF在初发型和复发型翼状胬肉中均有高度表达,且复发型表达率略高于初发型,提示TF可能在翼状胬肉的发生、发展中起重要作用,选择性抑制TF的表达途径有可能成为控制和治疗翼状胬肉的新方法。  相似文献

Antitryptic, antichymotryptic and alpha 2- macroglobulin activities were measured in sera of normal nonpregnant and normal pregnant women and women with tubal ectopic pregnancy and molar pregnancies in the first 5 to 7 weeks of pregnancy calculated from the last menstrual period. While alpha 2-macroglobulin decreased in early normal pregnancy compared to nonpregnant state (p<0.001), in ectopic and molar pregnancies there was an increase in alpha 2- macroglobulin activity (p < 0.001), as compared to nonpregnant and normal pregnant women. Antitryptic activity did not increase in normal and ectopic pregnancy, however was increased in molar pregnancy (p < 0.01). Antichymotryptic activities did not show a change either in normal pregnancy or in cases of ectopic and molar pregnancy. Drop in alpha 2- macroglobulin activity to near normal levels in ectopic, 6 weeks post surgery, correlated well with the decrease in β-hCG. However, in molar pregnancy, alpha 2- macroglobulin remained elevated even when the β-hCG levels in serum returned to zero 10 weeks after surgery. The studies suggest a major role for circulating proteinase inhibitors especially alpha 2-macroglobulin in regulating proteinase activity in normal, ectopic and molar pregnancy.  相似文献

Hemodynamic disorders of liver cirrhosis complicated with portal hypertension are associated with an increased angiogenesis in animal model of portal hypertension and cirrhosis which were linked to increased expression of vascular endothelial growth factor (VEGF) and nitric oxide (NO). The aim of study was to evaluate the serum concentration of VEGF and total nitric oxide (NO) in liver cirrhosis and the possible association with the degree of liver insufficiency. VEGF and NO were measured in serum of 64 patients with liver cirrhosis by ELISA and spectrophotometry respectively. The significant increase of serum VEGF was observed in liver cirrhosis compared to healthy individuals as well as serum NO (106.1 ± 66.7 vs. 41.5 ± 6 pg/mL, P < 0.05; 113.5 ± 65.8 vs. 20.8 ± 3.8 μmol/l, P< 0.001, respectively). Serum VEGF and NO showed significant associations with biochemical indices of liver function and with Child-pugh score where they were increased respectively to the degree of liver insufficiency. A significant association of raised serum NO in early stage of portal hypertension reflect its benefit in early expect of portal hypertension but, high serum VEGF in late stage may reflect its prognostic value in liver cirrhosis.  相似文献

This work was undertaken to investigate correlation between oxidative stress and initiation of pathogenesis of pregnancy induced hypertension (PIH). Fifty primigravidae in age group of 20–35 years and gestational age 28–42 weeks with PIH were taken as cases. Twenty healthy primigravidae with no medical and surgical complications of pregnancy and with blood pressure ≤140/90 mm Hg served as controls. The cases were again subgrouped as severe preeclampsia (12 in number) and mild pre-eclampsia (38 in number). All of them were evaluated for serum malondialdehyde (MDA), Serum vitamin E and plasma vitamin C levels. The serum MDA levels were raised significantly in women with mild preeclampsia (P<0.01) and in women with severe preeclampsia (P<0.01) in comparison to normal primi gravida. The serum vitamin E levels were decreased in primi gravida with mild preeclampsia (p<0.1) and in primi with severe pre eclampsia (P<0.1) in comparison to normal primi gravida but the fall was not statistically significant. There was a significant fall (P<0.05) in the vitamin C levels in primi with mild preeclampsia than in the normal primi. The vitamin C levels in severe preeclamptic patients were lower than the normal primi but the fall was not statistically significant (P=0.10). The serum MDA and vitamin E showed a negative correlation in all the cases. The serum MDA and plasma vitamin C also showed a negative correlation in the control and study group. This observation suggests that in hypertensive disorders of pregnancy there is an imbalance between lipid peroxidation and antioxidant vitamin status because of oxidative stress. The decreased serum concentrations of the antioxidant vitamins supports the hypothesis that lipid peroxidation is an important causative factor in the pathogenesis of preeclampsia. The rise in antioxidants is probably to compensate the increased peroxide load in severe preeclampsia.  相似文献

In this experimental study, a portable biosensor was developed to detect β-human chorionic gonadotropin (β-hCG), which is extensively used in pregnancy tests and serves as a biomarker for ectopic pregnancy. The sensor used is an electric-double-layer field-effect transistor biosensor with the extended-gate design. Bias voltage is applied on the sensor to measure the resulting drain current signals. Gold electrode surface is functionally activated with an anti-β-hCG antibody to capture β-hCG protein. Fluorescence imaging technique is utilized to confirm the surface functionalization. The biosensor demonstrates a dynamically wide range of molecules as detection targets at very low sample concentrations, which shows the potential to detect ectopic pregnancy in very early stages and easily keep track of its periodic changes. It can be produced en masse and does not use additional labels/reagents or pre-processing techniques for the sample. This biosensor can significantly reduce the manufacturing costs and is comparable with the currently available commercial ß-hCG assays. It is suitable for early diagnosis of ectopic pregnancy with low cost and easy operation at home with urine samples.  相似文献

大鼠是研究人类疾病的理想模型动物,而利用核移植手段是创造遗传修饰大鼠的最佳手段。但由于大鼠卵母细胞和胚胎发育的特殊性,克隆大鼠一直没有取得成功。我们在对大鼠卵细胞活化进行了深入研究的基础上,采用了全新的快速一步法体细胞核移植技术,并且利用蛋白激酶抑制剂(MG132)阻断大鼠卵母细胞减数分裂中期到后期的转变,成功地创造出有繁殖能力的体细胞克隆大鼠。该项研究为人类疾病的研究、相关药物的研制创造了条件。  相似文献
