Therapeutic effect of short-term administration of IFN-a on non-small cell lung cancer ( NSCLC) was observed . Seventy-two cases of NSCLC patients were randomized into two equal groups. The control and the IFN-a group received the same chemotherapeutic treatments while the latter group were also intramuscularly injected with IFN-? 1 ? 10~(6)U/day for 20 days. Treatment effect rate, the number of white blood cells, the growth of carcinoma cells and the in-terclude time of chemotherapy were studied. Statistically significant difference with each index was observed between the two groups. The results indicated that the short-term administration of IFN-? during chemotherapeutic suppression inhibited tumor growth and made a shortened chemotherapeutic treatment interval acceptable. All showed that administration of IFN-? was feasible and effective in NSCLC chemotherapeutic treatment.

Objective To investigate the relationship between expression of Survivin gene and biological characteristics in human esophageal carcinoma.Methods The expression of Survivin gene was detected in 62 cases of esophageal carcinoma tissues and tumor-adjacent normal tissues by immunohistochemical technique.Results The positive rate of Survivin expression in esophageal carcinomas was 79 0%,which was higher than that in tumor-adjacent normal tissues(6 5%,P0 05). The positive rate of Survivin expression in lymph node metastasis group (93 1%) was higher than that in the group without lymph node metastasis (66 7%,P

Objective To investigate the effects of inhibiting ubiquitin-proteasome pathway(UPP) on DNA synthesis and cell cycle in gastric cancer cell line SGC-7901. Methods The SGC-7901 cells were treated with MG-132, a specific inhibitor of UPP. The effect of MG-132 on cells DNA synthesis was assayed by 3 H-thymidine( 3H-TdR)incorporation. Cell cycle was analysed by flow cytometry(FCM). Results After treated with MG-132, DNA synthesis of SGC-7901 cells was significantly inhibited, the ratio of G 0/G 1 phase cells increased, and the ratio of G 2/M phase and S phase cells decreased. Conclusions MG-132 can significantly inhibit DNA synthesis of gastric cancer cells SGC-7901 and induce G 1 blocking. The data indicated that inhibiting UPP may be a new strategy to treat gastric cancer.

Objective To investigate the expression of vascular endothelial growth factor-C(VEGF-C) in human non-small cell lung cancer(NSCLC) and to elucidate its roles in lymph node metastasis and prognosis evaluation. Methods The expression of VEGF-C was examined in 50 NSCLC specimens and 20 archival surgical specimens of human pulmonary inflammatory pseudotumor tissues by immunohistochemistry. Results The positive rate of VEGF-C expression in NSCLC and inflammatory pseudotumor was 44% and 5% respectively. There was significant difference in VEGF-C expression between the two groups. The expression rate of VEGF-C in NSCLC was significantly higher in the patients with lymph node metastasis (66 7%) than that in the patients without lymph node metastasis (23 1%, P

Objective To investigate effect of p27kip1 gene transfer mediated by adenovirus vector on the cell cycle of esophageal carcinoma cells. Methods The recombination adenoviral vector carrying p27kip1 gene (Ad-p27kip) was transfected to esophageal carcinoma Eca9706 cells. The effect of p21kip1 gene transfer on the cell growth suppression was measured by MTT method. Expression of p27kip1 was detected by immunocytochemical technique. Cell cycle was analysed by flow cytometry(FCM). Results After Eca9706 cells were transfected with Ad-p27kip1, p27kip1 expression increased, the cell growth was significantly inhibited and the ratio of G 0/G 1 phase cells increased and the cell number of G 2/M and S phases decreased. Conclusion p27kip1 gene transfer mediated by adenovirus can significantly inhibit the growth of esophageal carcinoma cells and cause G 1 phase blocking.

Objective To compare the efficacy and side-effects of combined spinal-epidural anesthesia(CSEA)and epidural anesthesia(EA)for ureteroscopic pneumatic lithotripsy.Methods A total of 60 patients with ureteral calculi(ASA gradeⅠ-Ⅱ)were divided into A and B groups randomly(30 in each).CSEA was performed in group A,and EA was carried out in group B.Anesthetic effects and side-effects were observed in both the groups.Results Anesthetic effects were satisfying in both the groups,no patient had headache after the operation.The onset time of anesthesia in group A was shorter than that in group B [(7.2?4.1)min vs(17.4?3.3)min,t=-10.615,P=0.000].The level of motor block of CSEA was stronger than that of EA(?2=40.000,P=0.000).No significant differences were found between the two groups in the number of patients who developed hypotension(6 in group A and 3 in group B,?2=0.523,P=0.470)or shivering(9 in group A and 6 in group B,?2=0.800,P=0.371).Conclusions Both CSEA and EA are applicable to ureteroscopic pneumatic lithotripsy.CSEA is more efficient than EA.

Objective To study the expression of CD105 in laryngeal carcinoma and to evaluate the clinical significance of microvessel density(MVD).Methods Pathologic paraffin-embedded sections and clinical data from 40 patients with primary squmamous cell carcinoma of larynx were studied through immunohistochemistry.Microvessel density(MVD) highlighted by CD105 and CD34 were counted.Results CD105 expression in tumour tissue was significantly higher than normal health mucosa.The mean CD105-MVD value of T3 and T4 tumours showed a significantly deeper staining than T1 and T2;The mean CD105-MVD value of tumours with metastasis was also markedly higher than tumours with no metastasis;The diffenerce of mean CD105-MVD value between in 16 patients with recurred laryngeal carcinoma and in 20 patients with unrecurred laryngeal carcinoma for two years of follow-up was markedly significant(P

[Objective] To investigate the feasibility of posterior interbody parvule-impacted bone graft fusion.[Method] A retrospective study was performed in 31 patients admited to our hospital in 2003~2006(M=14,F=17).The ages were 55 to 80,with an average of 66.2 years.There were 9 cases of spondylolisthesis,6 of degenerative unstability and 16 of developmental stenosis.All patients underwent posterior interbody impact bone graft fusion and pedicle screw fixation.The pre-and post-operative JOA score were used to calculate the improvement rate.The postoperative bending-extending plain films were taken to observe whether the fusion was successful.[Result]All patients were followed up for 12~18 months.Three patient had leg symptoms at postoperation and were released 3 months later.Thirteen patients had fusion at 6 month,16 had union at 12 month,and 2 had union at 18 month.The lumbar lordosis angle and intervertebral height got significant restoration.The spinal fusion rate was 100%.No dura tear leakage of cerebrospinal fluid or wound infection was found.No graft absorption,displacement or collapse occurred.There were 16 cases excellent,12 cases good,and 3 cases fair.JOA score was 24~29(average 27.4?1.9)at postoperation.The improvement rate was 89.4%.[Conclusion] Posterior interbody parvule-impacted bone graft is a feasible fusion method.The method is simple and cheap,with advantages of less injury and high fusion rate.
