ABSTRACT
Objective:To detect the expression and clinical significance of β-tubulin Ⅲ in cancer tissue of the patients with colon adenocarcinoma,and to explore its clinical significance.Methods:A total of 111 colon adenocarcinoma tissue samples were obtained.According to the location of β-tubulin Ⅲ positive cells, all patients were divided into front group (n=72) and non-front group (n=39).The positive expression rate of β-tubulin Ⅲ in the patients with colon adenocarcinoma was detected with immunohistochemistry.The correlations among the expression of β-tubulin Ⅲ and gender,age,tumor differentiation, clinical stage, lymph node metastasis, recurrence and death were analyzed.Results: The expression levels of β-tubulin Ⅲ had no significant differences between the patients with different gerder,age,lymph node metastasis,clinical stages,death and recurrence.The positive expression rates of β-tubulin in cancer tissue of the patients had significant difference between front and non-front groups (χ2=8.76, P=0.01).Lowly-to-moderately differentiated tissue was more common in front group, and highly-differentiated tissue was more common in non-front group(χ2=6.88, P=0.03).There were significant differences in the expression levels of β-tubulin Ⅲ between cancer tissues with different differentiation degrees (χ2=5.74, P=0.04).In non-front group, lymph node metastasis was closely correlated with the expression of β-tubulin Ⅲ (χ2=6.02,P=0.05).The results of immunohistochemical staining showed that the β-tubulin Ⅲ positive-expressing cells were colored brown-yellow.The number of cells with positive β-tubulin Ⅲ expression was significantly increased in highly differentiated tissue compared with low-differentiated tissue.Conclusion:The expression of β-tubulin Ⅲ is closely related to tumor differentiation in colon adenocarcinoma tissue.The highly differentiated colon adenocarcinoma tissue is more common in non-front group in which the expression of β-tubulin Ⅲ is related to lymph node metastasis.
ABSTRACT
Objective:To explore the necessity of the preventive use of antibiotics and the effects of age and operation time on the efficacy of inguinal hernia repair without tension,and to elucidate the clinical significance of the preventive application of prophylactic antibiotics in inguinal hernia repair without tension.Methods:A total of 228 patients with inguinal hernia repair without tension were selected,amomg them 42 cases with high infection factors were treated with antibiotics (treated group),and 186 cases were not treated with antibiotics(untreated group) during the preoperative period.The prophylactic antibiotics were given 30 min before surgery,and the conventional dose was not used more than 48 h after surgery.All the cases were treated with artificial repair materials for the procedure of inguinal hernial repair without tension.The age,highest body temperature,white blood cell count,operation time,hospitalization time,and postoperative body temperature of all the 228 cases were recorded and analyzed statistically.Results:The preoperative and postoperative white blood cell counts had significant differences between the patients0.05).Compared with the patients with the operation time>90 min,the white blood cell count and hospitalization time of the patients with the operation time ≤90 min were increased (P90 min and the patients with the operation time≤90 min (P>0.05).The white blood cell count,operation time,hospitalization time and postoperative body temperature of the patients between treated group and untreated group had no significant differences (P>0.05).Conclusion:The use of antibiotics in the high-risk patients and non-use of antibiotics in the majority of elective inguinal hernia repair without tension can ensure the safe and performability of the patients.
ABSTRACT
Objective To study the value of transcatheter arterial chemoembolization (TACE)in combination with portal vein chemotherapy (PVC) after resection of hepatocellular carcinoma to prolong survival. Methods From January 2000 to July 2007, 168 patients with hepatocellular carcinoma (HCC) underwent tumor resection in our hospital. After operation, TACE in combination with PVC was performed in 48 patients (combined group), TACE alone in 26 (TACE group), PVC alone in 50 (PVC group) and none of the above in 44 (control group). All the patients were followed up for 17-96 months. The 1-, 3-and 5-year survival rates were compared among the 4 groups. Results Accumulative 1-, 3-and 5-year survival rates were higher in the combined and TACE groups than in PVC and control groups. Conclusion After resection of HCC, combined use of TACE and PVC is the same as TACE in prolonging patient survival. However, it is better than PVC alone and non-surgical procedure.
