Objective To study the expression of HPV、p16 and Her-2 in the squamous cell cervical carcinoma and its chnical significance. Methods Expression of HPV16/18、p16, and C-erbB-2 and the amplification of Her-2 gene were examined using situ hybridization technique,SP immunohistochemistry,and FISH imaging analysis system in 60 cases of cervical cancer, 61 cases of CIN, and 21 cases of normal cervical tissue,respectively.Results The positive rates of HPV16/18 and p16 in the normal tissue,CIN Ⅰ -Ⅱ,CINⅢ and the squamous cell cervical carcinoma were gradually increased, they wereo (0/21),9.68 ％ (3/31),46.67 ％ (14/30),71.67 ％ (43/60);0 (0/21),19.35 ％ (6/31),93.33 ％ (28/30),96.67 ％ (58/60),respectively,and there were significant differences among the groups (P＜0.05),but no significant difference was found between the normal tissue and the CIN Ⅰ - Ⅱ. The positive rates of Her-2 and Her-2 in the CIN Ⅲ and the carcinoma were 13.33 ％ (4/30),31.67 ％ (19/60),3.33 ％ (1/30),21.67 ％ (13/60),respectively,but in the normal group and the CIN Ⅰ - Ⅱ wereo,and the differences between the carcinoma group and the CIN group,the carcinoma group and the normal group were significant(P＜0.05).The expression of Her-2 and the amplification of Her-2 were closely related to the stage, degree of differentiation and metastasis of lymph node in the squamous cell cervical carcinoma (P＜0.05). Conclusion The infection of HPV is one of thetriggers for the squamous cell cervical carcinoma.The expression of p16 and the amplification of Her-2 may be closely correlated with tumor development and high expression of p16 and Her-2 indicates poor prognosis.

Objective To analyze the relationship between expression of Her-2 protein and the infection of human papillomavirus (HPV) and clinicopathological features in upper gastrointestinal multiple primary cancers, and to explore the relationship between the different histological malignancies in a single-system. Methods 39 patients were primary esophageal squamous cell carcinoma and gastric/cardia adenocarcinoma. By using immunohistochemistry (IHC) methods, the expression of Her-2 protein in 39 cases of multiple primary cancers specimens were examined, and by using insitu hybridization (ISH) technology, the infection of HPV in the same ones were detected. Results The over-expression of Her-2 protein in esophageal squamous cell carcinoma was not significantly relative to the degree of differentiation, the depth of penetration, the lymph node metastasis and the patientsˊage and gender (P> 0.05). The over-expression of Her-2 protein in gastric adenocarcinoma was closely correlated to the invasion depth and lymph node metastasis (P<0.05), no obvious correlation with the factors of patientsˊage and gender and the degree of differentiation (P > 0.05). The infection of HPV in esophageal squamous cell carcinoma and gastric adenocarcinoma was not significantly relative to the degree of differentiation, the depth of penetration,the lymph node metastasis, and the age and gender of the patients (P> 0.05). In the upper gastrointestinal multiple primary cancers, the Her-2 protein over-expression had the consistency (κ= 0.56, P< 0.05). Meanwhile, the HPV-DNA expression also had the consistency (κ=0.80, P<0.05). Conclusion Both Her-2 protein and HPV expression show the consistency in upper gastrointestinal multiple primary cancers,which suggests that Her-2 protein and HPV may be the common oncogenic factors for both esophageal squamous cell carcinoma and gastric adenocarcinoma.

Objective To investigate the relationship and clinicopathologic significance between the expression of CD95,CD44V6 and metastasis of axillary lymph node in breast cancer.Methods Immunohistochemistry was used to detect the expression of CD95 and CD44V6 in 101 cases of breast cancer, in which, 40 cases without metastasis in axillary lymph node were detected MCK expression by IHC. The results were analyzed statistically. Results 9 cases of breast cancer with lymph node micrometastasis were observed by IHC in 40 cases without metastasis in axillary lymph node by microscope. The expression of CD95, CD44V6 in lymph node metastasis group was similar as in lymph node micrometastasis group. There was significant difference of CD95 expression between those with lymph node metastasis and those without. The positive rate of CD95 and the high expression of CD44V6 in the cases that the tumor size was over 2 cm were significandy higher than in the cases that the tumor size was less than 2 cm (P<0.05). Conclusion Detection of the expression of CD95, CD44V6 in breast cancer may be helpful to predict the lymph node micrometastasis and provide more dependable evidence for judging prognosis and selecting treatment prescription clinically.

Objective To study the expression of Survivin and Caspase-3 in uterine smooth muscle tumour (USMT) and it' s significance. Methods Expression of Survivin and Caspase-3 protein were determined by immunohistochemistry Two-step method on 30 uterine Cellular Uterine Leiomyoma (CUL), 10 normal uterine smooth muscle (NSM), 10 Ordinary Uterine Leiomyoma (OUL), 15 Leiomysarcoma (LMS). Results Survivin level in normal uterine smooth muscle are very low, and in OUL, CUL, LMS was on increasing trend, the OL group and the LCA group have statistical significant difference(P<0.05). Caspase-3 level in NSM, OUL, CUL, LMS was on decreasing trend. The NSM group and the CL group, the NSM group and the LCA group both have statistical significant difference (P<0.05). Conclusion Maybe Survivin can inhibit apoptosis and extend cells lives by inhibit the activity of Caspase-3, so it played an important role in the development progress from benign uterine tumour to malignant uterine tumour. The detect of Survivin and Caspase-3 may be useful in the differential diagnosis of uterine smooth muscle tumours.

Objective To detect the correlation of immunophenotyping of DLBCL with Choi's and Han' s classification to the prognos is. Methods Ninty-nine cases of DLBCL were studied using immunohistochemistry EnVision method for bcl-6, CD10, FOXP1, GCET1, MUM1 in Shanxi cancer hospital. The follow-up was included. All cases they were classified according to Hans' s and Choi' s algorithm. Fluorescence in situ hybridization (FISH) for bcl-6 gene expression (located on chromosome 3q27) was performed on paraffin-embedded tissues of 35 cases. Results In Hans classification, 21 cases were GCB and 78 were nonGCB subtype. In Choi's classification, 23 cases were GCB and 76 cases were nonGCB subtype. According to the both classification, the prognosis in GCB group was much better than that in nonGCB's (P = 0.000). The expression of FOXP1 was inverse proportion to the prognosis (P =0.011), on the contrary GCET1 expression was in proportion to the prognosis (P =0.027). Among all of 35 DLBCL cases, bcl-6 rearrangement was more frequently encountered in the nonGCB type, bcl-6 gene rearrangement was no correlated to bcl-6 protein expression. Conclusion On the basis of classification, GCB group had a better clinical outcome than that of nonGCB group. FOXP1, GCET1, bcl-6 protein expression is associated with different outcome in DLBCL. Both of Choi's and Hans's algorithm play an important role in the immunophenotyping and prognosis.

Objective To investigate the dysregulation of HER-2 protein and gene in non-small cell lung cancer (NSCLC), and to identify the association between clinicopathological features,prognosis and HER-2 aberrations amongst protein and gene. Methods 140 NSCLC tissues (89 squamous cell carcinoma, 51 adenocarcinoma) with operative section and detailed case were taken from pathology department of Shanxi Cancer Hospital from Jan 2006 to Feb 2007, while 70 normal tissues were set as control group. Immunohistochemistry was applied to detect the state of HER-2 protein expression,and fluorescence in situ hybridization (FISH) was applied to test the status of gene amplification. Results In normal and NSCLC tissues, over-expression of HER-2 was detected in 0 case and 17 (12.14 %) cases (P < 0.05), respectively. The over-expression of HER-2 was associated with the pathological type of NSCLC, which was detected more frequently in adenocarcinoma (χ2 = 4.19, P = 0.04), rather than the gender, age, smoke history, clinical stages, and lymphatic metastasis of patients. 40 (28.57 %) cases presented HER-2 gene copy number ≥3, including 6 (4.29 %) patients with HER-2 gene amplification, 34 (24.29 %) patients with HER-2 gene multicopy. HER-2 gene amplification was associated with the pathological type (P = 0.024), smoke history (P = 0.048) and age (P = 0.015), rather than lymphatic, gender, clinical stages. None clinicopathological features were presented correlation with HER-2 gene multicopy (P > 0.05). There was no significantly difference in survival between patients with and without HER-2 protein over-expression and HER-2 gene dysregulation (P > 0.05). HER-2 protein over-expression was associated with HER-2 gene amplification (P > 0.05), while no relationship between HER-2 protein overexpression and HER-2 gene multicopy (P < 0.01). Conclusions The over-expression of HER-2 is related to pathological type of NSCLC with more frequent expression in adenocarcinoma. The incidence rate of HER-2 gene amplification in patients with adenocarcinoma histology, never-smokers, and young age is high. The HER-2 protein over-expression and gene dysregulation show no relation with the prognosis of NSCLC.
