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 investigate the expressions of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER-2) and relationships of these expressions with the clinicopathology in breast cancer patients aged 70 years old and over. Methods The expressions of ER, PR and HER-2 were detected by immunohistochemical staining from 124 elderly breast cancer patients, and the relationships of these expressions with pathological classification, tumor size, lymph node metastasis and TNM stage were analyzed. Results Among 124 patients, the positive expression rate of ER and PR was 75.0% (93/124) and 71.0% (88/124),respectively. They were not associated with pathological classification, tumor size, lymph node metastasis or TNM stage (all P>0. 05). The positive expression rate of Her-2(+++) and Her-2 (++) was 11.3% (14/124) and 24.2% (30/124), respectively. And the expression of Her-2 was significantly associated with tumor size, lymph node metastasis and TNM stage (P<0. 05) but not with pathological classification (P>0. 05). Conclusions The positive expressions of ER and PR are not correlated with the clinicopathology in elderly breast cancer patients. Her-2 overexpression is positively associated with tumor size, lymph node metastasis and TNM stage.

BACKGROUNDTo study the efficacy and long-term survival of high-dose chemotherapy supported by autologous peripheral blood stem cell transplantation (APBSCT) in the treatment of small cell lung cancer (SCLC)..
METHODSSeven patients with pathologically confirmed SCLC were enrolled into the study, including 6 patients who had achieved CR or PR after conventional chemotherapy, and 1 patient who underwent surgical treatment and 6 cycles of conventional postoperative chemotherapy. All patients received a high-dose chemotherapy regimen of cyclophosphamide 6 g/m², etoposide 1.2 g/m², carboplatin 1.2 g/m² following APBSCT. Six of 7 patients received local radiotherapy after the procedure, however, another patient over 60 years did not receive local radiotherapy because of pneumonia complication. All patients were consecutively followed up and median follow-up duration was 27 (25-82) months.
RESULTSSurvival of the 7 patients was longer than 2 years. Three patients were still alive for more than 5 years after treatment, and the longest one up to 82 months. Three patients died and their survival time was 26, 27 and 27 months respectively.
CONCLUSIONSHigh-dose chemotherapy supported by APBSCT combined with local radiotherapy may be helpful to prolong survival and improve prognosis for SCLC, especially to those patients with limited disease, relatively younger age and better performance status, and responding to conventional chemotherapy.

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.

OBJECTIVEThe efficacies of the selective 5-hydroxytryptamine3 (5-HT3) antagonists--ramosetron (0.3 mg) and granisetron (3 mg) in treating acute chemotherapy-induced digestive system dysunction were compared.
METHODSA total of 111 patients were enrolled in a single-blind, randomised crossover study; with data from 98 were used to assess efficacy and data from 110 to assess the safety profile. Ramosetron or granisetron was given intraveneously 15 min befire chemotherpy.
RESULTSThe ability of ramosetron to prevent emesis, nausea and anorexia was similar to granisetron during the first 6 h following the administration of chemotherapy, ciplatin or doxorubicin. However, during the first 24 h after chemotherapy, significant differences between ramosetron and granisetron appeared: emetic episode (P = 0.068), nausea (P = 0.006), and anorexia (P = 0.048) remained lower in ramosetron-treated patients. The safety profile of ramosetron was similar to that of granisetron and adverse events in both groups were generally mild and transient.
CONCLUSIONRamosetron is more potent and longer-lasting than granisetron in preventing chemotherapy-induced digestive disturbances.
