ABSTRACT
Purpose To compare the difference of the genotype and allele of endothelial cell protein C receptor (EPCR)gene rs9574 C/G between Guangxi population and other ethnic groups.Methods The rs9574 C/G polymorphisms of EPCR in 130 cases of Guangxi population were detected by PCR and DNA sequencing.The distribution frequency of allele and genotype was compared with the other four ethnic groups (HapMap-CEU,HapMap-HCB,HapMap-JPT,HapMap-YRI),which was published by the human genome project.Results Three genotypes of CC,CT and TT were found in rs9574 C/G with the frequencies of 39.2％,46.2％,14.6％ respectively.the allele frequencies of C,T were 62.3％ and 37.7％.No significant difference was observed in the frequency of genotype and allele between male and female (P ＞ 0.05).There were significant differences in the genotype distribution among Guangxi population,HapMap-CEU and HapMap-YRI (P ＜ 0.05).Significant differences of allelic frequency were found among Guangxi population,HapMap-CEU,HapMap-JPT and HapMap-YRI.Condusion The polymorphisms of rs9574C/G in 3'-noncoding region of EPCR gene in Guangxi population were different in different regions and ethnic groups.
ABSTRACT
Objective To investigate the expression and clinical significance of FoxA 2(hepatocyte nuclear factor 3β)in human non-small cell lung cancer(NSCLC)tissues and adjacent normal lung tissue.Methods The expressions of FoxA 2 protein in 80 cases with NSCLC tissues and adjacent normal lung tissue were tested by immunohistochemistry,the expressions of mRNA was detected by RT-PCR.Results The expressions of FoxA 2 both on protein and mRNA in NSCLC lung tissue were significantly less than those of adjacent normal lung tissue(protein expression comparison t value was 187.51,186.43,178.24 respectively;mRNA expression comparison t value was 236.70,260.13,126.27,respectively,P ＜ 0.05).However there was no difference on histopathological variability.F value equal to 1.86 and 1.69,P ＞ 0.05).In low differentiated group,the group of Ⅲ stage,with lymph node metastasis,the expression of FoxA 2 protein and mRNA was less than that in the group of high differentiated,the group of Ⅰ-Ⅱ stage,the group of non lymph node metastasis(pretein expression t values were 4.31,3.92,341,mRNA expression t values were 5.44,3.28,5.07,P＜0.05).Conclusion FoxA 2 might inhibit progression of human NSCLC.It may participate in the process of tumor tissue differentiation and lymph node metastasis in NSCLC.
ABSTRACT
AIM: To observe clinical efficacy of Tanreqing Injection (Radix Scutellariae, Bear gall powder, Ram's horn, Flos lonicerae japonicae and Fructus forsythiae) in treatment of patients with acute attack of bronchial asthma. METHODS: One hundred and seven patients with an acute asthma were randomly assigned into two groups: a treatment group (n=52, treated by Tanreqing Injection for 10 d in addition to the routine medications) and a control group (n=55, treated by routine medications). The serum levels of ET and TNF-α were determined by radioimmunoassay before and after treatment, respectively. RESULTS: Before treatment, there were no significant differences in the content of serum ET and TNF-α between the treatment group and the control group. However, after 10 d of treatment, the levels of ET and TNF-α inthe treatment group were significantly lower than those of the control group (P<0.01), and clinical efficacy of the treatment group was superior to the control group. CONCLUSION: Inhibitionof ET and TNF-α secretion and intervention inflammatory response might be one of mechanisms of Tanreqing Injection in treatment for acute asthma.
ABSTRACT
Objective To explore the diagnosis rate.pathology types and positive rate of cancer cell in spu-tum of early central pulmonary carcinoma in three obstructive signs on chest X ray screened by fiberbromchoscope.Methods 326 cases of three obstructive signs with high risk of lung cancer were screened for central pulmonarycarcinoma by spiral CT.biopsy by fiberbronchoscope and cytological examination of sputum.Results 32 patients were diagnosed with central pulmonary carcinoma,with morbidity of 9.8%.In these patients,21 were confirmed with obstructive pneumonia(65.6%),7 with obstructive atelectasis(21.9%),4 with obstructive emphysema(12.5%);In terms of pathology type,16 cases were defined as squamous cell carcinoma(50.0%),9 as small cell carcinoma(28.1%).3 were as large cell carcinoma(9.4%).2 were as adenocarcinoma(6.3%),1 as admosquamous carci-noma(3.1%),1 as bronchial gland carcinoma(3.1%);cancer cell could be found in sputum of 5 patients of 32 cases,among them,it was found in 3 of 21 patients with obstructive pneumonia(14.3%),1 in 7 patients with ob-structive atelectasis(14.3%),1 in 4 patients with obstructive emphysema(25.0%).Conclusion The prevelance of early central pulmonary carcinoma in three obstructive signs on chest X-ray is 9.815%,in which squamous carci-noma and small-cell carcinoma are common in pathology type.Screening can increase the detection rate of early pul-monary carcinoma.
