Objective:To study the expression of NF-?Bp65 and bcl-x L gene in pancreatic carcinoma and their clinical significance.Methods:The expressions of NF-?Bp65 and bcl-x L protein in 52 pancreatic carcinoma were studied by immunohistochemistry,and their relationship to clinical pathology were analyzed.Results:The positive rates of NF-?Bp65 protein and bcl-x L protein in pancreatic carcinoma were 63.5% and 73.1% respectively,and which were higher than those of normal pancreatic tissues.The expression of NF-?Bp65 was related to tumor diameter,TNM stage and lymph node metastasis,and had no relation with the extent of differentiation and type of pathology.There was positive correlation between NF-? Bp65 and bcl-x L expression.Conclusion:NF-? Bp65 may be an important oncoprotein,and may have positive regulation on bcl-x L,then promote tumorgenesis.

Objective :To investigate expression of E-Cadherin(E-CD) in breast cancer cells and its relationship to clinical and pathological character and to the incidence of tumor cells shed from the surgical field. In an attempt to study more deeply about the mechanisms of invasion and metastasis of breast cancer and give some reference to the diagnosis and treatment of breast cancer. Methods: The expressions of breast carcinoma cells were studied using immunohistochemical methods(ABC methods).Semi-quantitative methods were used to judge the results. For statistical analysis, Chi-square test and the exact probability in 2 ?2 table were used. Results : E-CD positive was located on cell membranes and cytoplasms, mainly on membranes, showing different intensity of brown pellet. Of 52 cases, twenty nine percent retained normal E-CD expression, seventy one percent have reduced or even none expression. E-CD expression has significant correlation with histological grade. Reduced and lost expression rate in Grade 1(36.4%,4/11) were much lower than grade 2(77.8%,28/36)and grade 3(75%,6/8) (p

Objective:To investigate the expression of lysozyme in ampullary carcinoma, and its relation with invasion, metastasis and prognosis. Methods: 36 cases were analyzed with immunohistochemistry of lysozyme. Results: The lysozyme-positive rate in patients with lymph node metastasis (30%) was significantly lower than that in patients without metastasis (71%), while that in patients with advanced cancer invading the pancreas (35%), was significantly lower than that in patients with cancer without invasion of the pancreas. The Survival rate of lysozyme-positive patients (66.7%) was significantly higher than that of lysozyme-negative patients (14.3%). Conclusion: The expression of lysozyme in carcinoma of ampulla is associated with invasion, metastasis and prognosis. Lysozyme is important in typing of cancer of ampulla.

Methods The expression of NF-?Bp65 and VEGF in 56 gastric carcinomas was detected with immunohistochemistry and compared with benign tissues. Results The positive rates of NF-?Bp65 and VEGF in 56 gastric carcinomas were 62.5% and 76.8% respectively,and which were higher than those of gastric mucosal atypical hyperplasia (33.3% and 44.4%) and the normal gastric mucosa(0 and 8.3%) (P0.05). There was positive correlation between NF-?Bp65 and VEGF expression (r=0.36,P

Objective To study the apoptosis of gallbladder carcinoma cell line GBC-SD induced by antisense oligodeoxynucleotide (ASODN) targeting survivin. Methods ASODN targeting survivin was transfected into GBC-SD cells mediated by lipofectin. Cultured cells were divided into 3 groups: control group,sense oligonucleotide (SODN) group and ASODN group. After transfected for 16 h, the cultured cells were harvested and the following texts were carried out. The expression of survivin mRNA was detected by RT-PCR. Flow cytometer were used to detect apoptosis. Morphological changes were observed by electron microscopy. Results The expression of survivin mRNA was decreased 47.83% in ASODN group while apoptosis was increased from (0.50?0.23)% to (26.28? 3.91)%. Abnormal morphological changes of cells were observed in ASODN group and apoptosis bodies were found in some gallbladder carcinoma cells. Conclusion The expression of survivin may be decreased in GBC-SD cells after ASODN transfection.ASODN targeting survivin could induce gallbladder carcinoma cells apoptosis effectively.

Objective: To set up the animal model of precancerous lesion of rats' pancreatic acinar cellular cancer,and to learn estrogen's effect on this lesion's biological feature and K-ras gene mutation. Methods: male Wistar rats were injected Azaser-ine 30mg/kg(ip). Some rats received Estradiol-17 P Valerate(0.18mg/100g/2weeks, im) .4 months later, rats'pancreas were autopsied and K-ras gene mutation were detected by PCR-SSCP method. Results : The incidence of AACN were very high. The incidence of K-ras gene mutation was 42.1% in rats without estrogen and 25.6% with estrogen. Conclusion: Azaserine could induce precancerous lesion of rats' pancreatic acinar cancer successfully, K-ras gene mutation was early change during this process Estrogen could inhibit this precancerous lesion's happen and development to some degree.

Objective To understand the sensitivity of cytopathogenic effect (CPE) in MadinDarby canine kidney cells(MDCK) that cultured influenza A pharyngeal swab specimens of patients for one,two and three passages. Methods Influenza A pharyngeal swab specimens of patients were inoculated in MDCK for three blind passages. The presence of CPE of every passage was observed by inverted microscope. Results Of the 279 influenza A pharyngeal swab specimens of patients tested by colloidal gold, the presence of CPE in MDCK for one,two and three passages was 65.9%(184/279),91.4%(255/279) and 96.4%(269/279), respectively. Two hundred and seventy-one of 279specimens were identified as influenza A by multiplex reverse transcription-polymerase chain reaction (RT-PCR). Conclusion The positive separation rate can reach more than 95% by inoculating influenza A pharyngeal swab specimens of patients in MDCK for three blind passages.
