Objective:To investigate the expressions of tumor stem cell marker CD133 and tumor vascular endothelial cell marker CD105 in lung cancer tissue and their clinical significance.Methods:Streptavidin-biotin-peroxidase complex (SABC)-immunohistochemical staining was used to detect the expression of CD133 and CD105 in 65 cases of lung cancer tissue and 30 specimens of adjacent non-cancerous tissue. The relationship between the expression of CD133/CD105 and tumor size, histological types, differentiation, TNM stage, lymphoid metastasis, and prognosis were analyzed. Results:The positive expression rates of CD133 and CD105 in lung cancer tissues were significantly higher than those in adjacent non cancerous tissues, respectively (69.2% vs 26.7% and 67.7% vs 10.0%, both P<0.05). The positive expression rates of CD133 and CD105 in the group with lymphoid metastasis were higher than those with non lymphoid metastasis, respectively (82.5% vs 48.0% and 80.0% vs 48.0%, both P<0.05). The expressions of CD133 and CD105 were positively correlated with lymphoid metastasis with Pearson coefficient r of 0.35 and 0.32, respectively (P<0.05). No significant correlation was found between the expression of CD133/CD105 and tumor size, histological types, differentiation degree as well as TNM stage(P>0.05). The expression of CD133 was positively correlated with the expression of CD105 in lung cancer tissue with Pearson coefficient r of 0.37 (P<0.05). Postoperative median survival periods of CD133 and CD105-positive group were significantly shorter than the CD133 and CD105-negative groups (37 months vs 66 months,35 months vs 70 months, respectively, both P<0.05). Conclusion:The expression of CD133 and CD105 was associated with lymphoid metastasis and prognosis in patients with lung cancer.Their overexpression implies poor prognosis of lung cancer patients.

Purpose To investigate the clinical efficacy of percutaneous radiofrequency ablation and microwave ablation in the treatment of primary hepatic carcinoma.Materials and Methods Ninety-two patients with primary hepatocellular carcinoma (116 lesions) were randomly divided into 46 cases of radiofrequency ablation group and 46 cases of microwave ablation group, which were treated with radiofrequency ablation and microwave ablation, respectively, the ablation points and ablation time, complete ablation rate, local tumor progression rate, postoperative complications, hospitalization time, hospitalization expenses, recurrence rate and relapse-free survival rate 1 year, 2 years and 3 years after surgery were compared and analyzed.Results There was no significant difference between the two groups in average ablation points (P>0.05), and the ablation time of microwave ablation group was significantly shorter than that of radiofrequency ablation group (P<0.01). There was no significant difference in complete ablation rate and local tumor progression rate between the two groups (P>0.05). The difference of complete ablation rate and local tumor progression rate between the two groups of tumor <3 cm, tumor 3-5 cm and tumor near the vessel were not statistically significant (P>0.05). There were no significant differences in the incidence of fever, pain in liver area and average length of hospitalization between the two groups (P>0.05). The average hospitalization cost of microwave ablation group was significantly lower than that of radiofrequency ablation group (P<0.01). There was no statistically significant difference of the cumulative recurrence rate for 1 year, 2 years, 3 years after surgery between the two groups (P>0.05). There was no significant difference between the two groups in the overall relapse-free survival rate and relapse-free survival rate among tumors with different size of the two groups (P>0.05).Conclusion Using microwave ablation for the treatment of primary hepatocellular carcinoma shows a clinical efficacy and safety as good as radiofrequency ablation. Radiofrequency ablation may have better therapeutic effect for smaller tumors, but microwave ablation may have some advantages for medium or large tumors and tumors located near the vessels.

Objective To evaluate the indeterminate growth mutant of tomato derived by space mutagenesis to provide the basis for selecting and cultivating the molecular markers of tomato growth habit. Methods Fifty 10-mer randomly amplified polymorphic DNA(RAPD) primers were used to examine the polymorphism of M1 and 10-3-2. Their polymorphic fragments were cloned, and then were transferred to SCAR markers. Results Of all the 50 10-mer RAPD primers, 44 primers amplified polymerase chain reaction(PCR) products and 2 primers (S165 and S168) amplified stable reproducible polymorphic products. The molecular weight of the specific amplified products were 300 bp and 1 500 bp respectively, therefore they were named as TRS165300 and TRS1681500 temporarily. And TRS1681500 was transferred into stable sequence characterized amplified region(SCAR) marker and this marker could be a specific genetic marker of this indeterminate growth habit mutant. Conclusion Space mutation can produce mutants at DNA level from the loaded materials. The indeterminate growth mutant of tomato is derived by space mutagenesis which can provide a valuable material for studying the regulation and control of tomato growth habit.
