5cm were 64.7% and 58% respectively(P0.05),The rate for patients aged0.05)。The positive rate of VEGF expression was 73.8%(62/84).The expression of VEGF was significantly associated with that of HIF-1?(P

Objective:To investigate the expression of cyclooxygenase-2 (COX-2) and vascular endothelial growth factor-C (VEGF-C) in papillary thyroid carcinoma and their relationship to cervical lymph metastases.Method:In this study, the expressions of COX-2 and VEGF-C were examined by immunohistochemistry in papillary thyroid carcinoma tissues of 40 patients, and analysis was performed on the correlation of cervical lymph metastases with COX-2 and VEGF-C expression.Result:Positive expressions of COX-2 and VEGF-C were 70.0%(28/40)and 75.0%(30/40)respectively in papillary thyroid carcinoma. The positive rates of COX-2 and VEGF-C expression were 80.8%(21/26)and 84.6%(22/26)respectively in patients with cervical lymph metastases, and 50.0%(7/14)and 57.1%(8/14)respectively in patients without cervical lymph metastases, with a statistically significant difference between two groups(P<0.05, all). COX-2 was positively correlated to VEGF-C expression in papillary thyroid carcinoma(r=0.378, P<0.05).Conclusion:The results suggest that COX-2 and VEGF-C were highly expressed in papillary thyroid carcinoma, with possible interaction of their expressions, and may play a critical role in the cervical lymph metastases of papillary thyroid carcinoma.

Objective:To explore the effect of radiotherapy on the FHIT protein expression and cell apoptosis of cervical squamous carcinoma and discuss the relationship between FHIT protein expression and cell apoptosis. Methods:Expression of FHIT protein was measured by immunohistochemical method and cell apoptosis was detected by TdT-mediated dUTP terminal nick end labeling (TUNEL) staining in 50 cases of squamous cell cervical carcinoma at ⅡB-ⅢB stages before, during (Dt 10 Gy and Dt 30 Gy), and after radiotherapy. Results:Of the 50 patients, the positive rates of the expression of FHIT protein was 56% at Dt 10 Gy, 68% at Dt 30 Gy, and 84% after radiotherapy, which were significantly increased compared with that before radiotherapy (36%, P<0.05). The positive rates of cell apoptosis was 52% at Dt 10 Gy, 64% at Dt 30 Gy and 78% after radiotherapy, which were significantly elevated compared with that before radiotherapy (28%, P<0.05). In the process of radiotherapy, cell apoptosis was positively related to the expression of FHIT protein (P<0.05). Conclusion:Radiotherapy reinforces the expression of FHIT protein and induces apoptosis cocurrently. FHIT protein has regulatory effects in cell apoptosis induced by radiotherapy.

Objective To study the effect of extended nursing on puerperal melancholia incidence.Methods Two hundred perpetrates received interventions of extended nursing after delivery,including education about puerperal state,turning on hot line and creation of QQ group,follow-ups and supporting from family members.Result The incidence rate of puerperal melancholia since performance of extended nursing was significantly lower than what is after its performance(P<0.01).Conclusions The extended nursing can help perpetrates to receive nursing knowledge,alleviate their anxiety,strengthen the confidence to take care of baby.As the result,it can reduce the incidence of puerperal melancholia.

Objective To detect epidermal growth factor receptor (EGFR) 19, 21 exon gene mutation and gene copy number in lung adenocarcinoma tissue, and to analyze the relationship of EGFR 19, 21 mutation with copies number. MethodsEGFR mutations and gene copy number in the tissue samples embedded by paraffin and fixed by for marlin from 58 cases of lung adenocarcinoma were detected by RT-PCR and FISH. The statistical data were analyzed by chi-square test.ResultsOf 58 cases, the overall single mutation rate of EGFR exon 19, 21 was 43.1% (25/58), and 2 cases contained both types of the mutation.The overall FISH positive rate of EGFR was 51.7 % (30/58), including 8 positive amplification and 22 highly ploidy amplification. The testing results showed that there had no statistically differences in FISH positive rates of EGFR mutation among different differentiation lung adenocarcinoma tissues(P ＞0.05), and the FISH positive rates of EGFR mutation in poorly differentiated cancer were lower than those in moderatedly differentiated and well-differentiated cancer (P ＜0.05). EGFR mutation was closely related to EGFR gene copies (P ＜0.01). ConclusionThere are high EGFR mutation frequencies and FISH positive rates in lung adenocarcinoma tissue; Combined detection of EGFR mutation and gene copy number may provide a better approach in selecting patients who may benefit from anti-EGFR target therapy.

Objective: To investigate the relationship between P27，P53 and PCNA expression in human gastric carcinoma tissues and clinicopathological parameters. Methods: The expression of P27，P53 and PCNA in 62 human gastric carcinoma tissues was examined with immunohistochemistry SP method. Results: Positive rates of P27，P53 and PCNA expression were 37.1％, 40.4%，83.9％. P27 expression was related with Bormann type, infiltrative depth, lymph node and distant metastasis and clinical stage. P53 expression was related with sex of patients, distant metastasis and clinical stage. PCNA expression was related with age of patients and infiltrative depth of tumor. P27 positive expression group was higher than negative group as to 5-year survival. P27 expression was in reverse relation with PCNA expression. Conclusion: The expression of P27, P53 and PCNA may be regarded as an important marker in judging malignant degree of gastric carcinoma,distant metastasis and prognosis.

Objective To study the expression of pl6, FHIT genes in cervical carcinoma and its clinical significance. Methods By immunohistochemistry SP method, the expression of pl6, FHIT in different 118 cases of cervical lesions were detected and the results were analyzed in combination with clinical pathological features. Results Of 118 patients, 15 cases suffered cervicitis;38 cases took place cervical tumor-like changes;65 cases caught cervical cancer. p16 expression rates were 0, 33.3 %, 70.0 %, 87.5 %,and 92.3 % respectively;while FHIT expression rates were 73.3 %, 75.5 %, 60.0 %, 37.5%, and 30.8 % respectively. Compared with cervicitis, pl6 and FHIT expression rates in the cervix tumor-like changes,cervical carcinoma had significant difference (P <0.05). There was positive correlation in protein expression between p16 and FHIT (x2 =33.33, P <0.001). Conclusion Combination of p16, FHIT detection can be used as early diagnostic tool of cervical lesions and cervical cancer markers;meanwhile, the method can serve as a clinical evaluation of tumor biological behavior and prognosis of auxiliary indexes.

Objective To investigate the expression fragile histidinetriad (FHIT) protein in cervical carcinoma and its relationship with clinicopathological feature of the disease. Methods Immunohistochemistry SP was used to detect the expression of FHIT protein in 20 cases with chronic cervsis and 95 cases with Ⅰ aⅢ b stage cervical carcinoma before and after treatment. The association of the expression of FHIT with clinicopathological feature was analyzed by the statistical method. Results There were significant differences between FHIT expression and histological grades and types of tissue, lymph node metastasis and invade depth (P ＜0.05). FHIT expression was not correlated with age and clinical stage (P ＞0.05). There were significant differences in FHIT protein expression levels in the patients with cervial cancer between before-after radiotherapy and the levels before radiotherapy was lower then those after radiotherapy (P ＜0.05). There was positively correlated in FHIT protein expression rates before and after radiotherapy (P ＜0.05). There were significant correlation between FHIT expression and 3-year survival rate, the positive rates of the expression FHIT protein higher then negative ones (P ＜0.05). Conclusion FHIT protein has great reference value that could be as a parameter for evaluating biological action and predicting the prognosis of cervical cancer.
