Relationship of p21WAF1 gene polymorphisms with protein expression in breast carcinomas

AIM: To investigate the relationship between p21^WAF1gene polymorphisms and protein expression in breast carcinoma. METHODS: Polymerase chain reaction single-strand conformation polymorphisms technique (PCR-SSCP) and immunohistochemical assay of S-P immunostaining technique were used to study polymorphisms of p21^WAF1 and protein expression respectively on the specimen of paraffin-embedded tissues in 100 cases of breast carcinomas and 40 benign breast diseases as control. RESULTS: Two p21^WAF1 gene polymorphisms were found in 18% (18/100) of breast carcinomas and 5% (2/40) of control samples. The difference between the two groups was statistically significant (χ²=3.94, P＜0.05). The positive immunohistochemical reaction of p21^WAF1 protein were found in 50% (50/100) of breast carcinomas and 12.5% (5/40) of control samples. The difference between the two groups was statistically significant (χ²=16.84, P＜0.01). The positive immunohistochemical reaction of p21^WAF1 protein were found in 100% (18/18) of breast carcinomas with p21^WAF1 gene polymorphisms and 39% (32/82) of no p21^WAF1 gene polymorphisms. The difference between two groups was statistically significant (χ²=21.95, P＜0.01). The p21^WAF1 gene polymorphisms were correlated with the protein expression in breast carcinomas (r=0.576, P＜0.01). CONCLUSION: p21^WAF1 gene polymorphisms may create the different copies of mRNA and may make relevant protein molecules.     

Effects of fosinopril,captopril and valsartan on the expressionof tissue factor in human monocytes

AIM: To investigate the effects of angiotensin-converting enzyme inhibitors (ACEI), fosinopril, captopril and angiotensin II AT₁ antagonists, valsartan on tissue factor (TF) expression on monocytes induced by lipopolysaccharide (LPS). METHODS: Mononuclear leukocytes from normal delivered female umbilical veins were incubated with bacterial LPS in presence or absence of different ACE inhibitors .At the end of incubation, the cells were disrupted by 3 freeze-thaw cycles. TF procoagulant activity was assessed by a one-stage clotting assay. RT-PCR was used to check TF mRNA expression, and GAPDH mRNA was used for parallel assay. RESULTS and CONCLUSION: The results showed that increased expression of TF mRNA induced by LPS was inhibited by fosinopril, captopril and valsartan, respectively, and the procoagualant activity of monocytes was also reduced.

含水率对安溪县花岗岩崩岗土体胀缩特性的影响

崩壁土壤水分变化是导致崩岗发生和发展的主要因素之一。降雨可以导致崩岗崩壁失稳发生崩塌,降雨过程中土体在不同含水率下的胀缩特性是决定崩壁失稳的关键因素之一。本研究以安溪县典型崩岗崩壁土体为对象,通过室内无荷膨胀率和线性收缩率试验,研究不同梯度含水率对崩壁不同土层胀缩特性的影响。结果表明:不同土层的无荷膨胀率均随初始含水率增大而减小,线性收缩率则相反。初始含水率与崩壁不同层次土壤无荷膨胀率之间存在着明显的指数递减关系,各土层拟合所得到的回归方程均可表达为:δ_e=ae⁽(–ω/b))+c,R²>0.96;初始含水率与崩壁不同层次土壤线性收缩率之间则存在着明显的指数递增关系,各土层拟合所得到的回归方程均可表达为:δ_sl=ae⁽(ω/b))+c,R²>0.96。对于同一土层,膨胀的变化幅度大于收缩的变化幅度。比较不同土层的膨胀和收缩变化幅度发现,红土层变化幅度最大,分别较砂土层高2.58%和3.33%,较碎屑层高3.61%和4.67%。这种不可逆的干湿胀...
