ObjectiveTo investigate the clinical value of veress needle with thread for laparoscopic high ligation of hernia sac in children. MethodsThe clinical data of 56 cases of pediatric inguinal hernia using laparoscopic high ligation of hernia sac with veress needle from May 2013 to May 2014 were analyzed retrospectively. ResultsAll patients were successfully carried out operation by laparoscopic high ligation of hernia sac.Forty-one cases underwent unilateral surgery, and operative time was 6-18 min (mean 9.6 min); 15 cases underwent bilateral surgery, and operative time was 10-32 min (mean 14.3 min).Nine cases of contralateral recessive hernia were found and ligated during operation.There was no complications, such as scrotal edema, scrotal gas or incision infection after operation, and all patients were discharged in l-2 days after operation.No recurrence or testicular dysplasia was found during 3 to 15 months (mean 10.8 months) follow-up. ConclusionsThere are many advantages in laparoscopic high ligation of hernia sac with veress needle, such as less damage, hidden incision, faster recovery, shorter hospital stay, simple operation, and better efficacy.We can find contralateral recessive hernia during operation and avoid second surgery with high clinical value, therefore it is worthy of clinical application.
ObjectiveTo study the expressions of cyclooxygenase-2(COX-2) and Ki-67 in the invasive ductal carcinoma (IDC) of breast and to analyze its clinical significance. MethodsImmunohistochemical SP method was performed to detect the expressions of COX-2 and Ki-67 in 82 cases of IDC of breast and corresponding tumor-adjacent normal breast tissues, and the relationship of these expressions to clinicopathologic characteristics was analyzed. Results①The positive rates of COX-2 and Ki-67 protein expressions in the IDC of breast tissues were significantly higher than those in the corresponding tumor-adjacent normal breast tissue [COX-2:71.95%(59/82) versus 8.54%(7/82), χ2=68.56, P < 0.001;Ki-67:64.63%(53/82) versus 13.42%(11/82), χ2=45.20, P < 0.001].②The positive rates of COX-2 and Ki-67 protein expressions were positively correlated with TNM staging (COX-2:rs=0.349, P < 0.05;Ki-67:rs=0.305, P < 0.05), lymph node metastasis (COX-2:rs=0.336, P < 0.05;Ki-67:rs=0.419, P < 0.01), vascular invasion (COX-2:rs=0.235, P < 0.05;Ki-67:rs=0.461, P < 0.01), and histological grade (COX-2:rs=0.434, P < 0.01;Ki-67:rs=0.378, P < 0.05).The positive rate of Ki-67 protein expression was positively correlated with tumor diameter (rs=0.365, P < 0.01), but the positive rate of COX-2 protein expression wasn't correlated with it (rs=0.135, P > 0.05).The positive rates of COX-2 and Ki-67 protein expressions weren't correlated with menstrual status (COX-2:rs=0.172, P > 0.05;Ki-67:rs=0.163, P > 0.05).③The positive rate of COX expression was positively correlated with the positive rate of ki-67 expression (rs=0.475, P < 0.01). ConclusionsThere are high-expressions of COX-2 and Ki-67 in IDC of breast.COX-2 and Ki-67 are significantly correlated with the clinicopathologic characteristics in IDC of breast.Combined detection of COX-2 and Ki-67 might calculate the biological behaviors of IDC of breast.COX-2 might be a target of molecular targeted therapy to breast cancer.
ObjectiveTo investigate the correlation between the expressions of matrix metalloproteinase-3 (MMP-3) and vascular endothelial growth factor (VEGF) in the three negative breast cancer (TNBC) and analyze their clinicopathologic significances. MethodsOne hundred and twelve patients confirmed TNBC from January 2008 to January 2013 in this hospital were collected. The cases of luminal type with the similar pathological type and pathological staging were chosen as control. The expressions of MMP-3 and VEGF were detected by immunohistochemistry. Results①The positive expression rates of MMP-3 and VEGF in the TNBC tissues were significantly higher than those in the luminal tissues[MMP-3:90.18%(101/112) versus 49.11%(55/112), P < 0.05;VEGF:84.82%(95/112) versus 48.21%(54/112), P < 0.05]. 2 The positive expressions of MMP-3 and VEGF in the TNBC tissues were correlated with age, menopausal status, tumor size, axillary lymph node metastasis, and TNM stage(P < 0.05).③The expression of MMP-3 was positively correlated with VEGF in the TNBC tissues(rs=0.711, P < 0.01).④The results of follow-up showed that the recurrence and metastasis rate within 3 years was 73.21%, the survival rate within 5 years was 36.61% in the patients with TNBC. ConclusionsThere is a close relation between MMP-3 and VEGF in TNBC, the expressions of MMP-3 and VEGF may serve as important biomarkers for evaluating invasion and metastasis in TNBC. There is a higher metastasis rate within 3 years and a lower survival rate within 5 years in TNBC. According to intervening the expressions of MMP-3 and VEGF, and inhibiting cancer cells matrix degradation and vascular formation, then cancer cells metastasis could be blocked, it may be important to reduce the 3-year recurrence rate and improve 5-year survival rate.
ObjectiveTo explore the clinical significance of hepatectomy combined with vascular reconstruction in hilar cholangiocarcinoma with vascular invasion. MethodsThe clinical data of 62 cases of hilar cholangiocarcinoma with vascular invasion in Suqian People's Hospital of Nanjing Drum-Tower Hospital Group from January 2006 to January 2014 were analyzed retrospectively. All cases were divided into two groups according to assessment of surgical trauma tolerance, nutritional status, and family's wishes. Thirty-three cases underwent hilar cholangiocarcinoma radical operation and hepatic artery combined with portal vein resection and reconstruction (combined resection group), while 29 cases of hilar cholangiocarcinoma underwent palliative surgery for treating jaundice in synchronization (palliative operation group). ResultsThe median survivals in combined resection group and palliative operation group was 26.3 and 9.6 months, respectively. The survival rates of 1-year, 2-year, and 3-year between combined resection group and palliative operation group were 84.85% vs. 26.32%, 66.67% vs. 15.79%, and 42.42% vs. 0, respectively, there were significant differences between both groups in survival time and survival rate (t=4.470, P=0.000; χ2=28.338, 20.348, and 15.891, P=0.000). Among of 33 cases in combined resection group, postoperative complications occurred in 9 cases, the rate of complications was 27.27% and the mortality rate in perioperative period was 3.03%; while postoperative complications in palliative operation group occurred in 5 cases, the rate of complications was 17.24%, no case died in the perioperative period. There were no significant difference between both groups in the rate of postoperative complications and the mortality rate in perioperative period (χ2=0.888, P=0.346; χ2=0.893, P=0.345). ConclusionsHepatectomy combined with vascular resection and reconstruction can significantly improve the radical resection (R0) rate of HCCA, and greatly increase the 1-year, 2-year, and 3-year survival rates of patients. Furthermore, complications can be controlled, and the mortality rate in perioperative period does not increase.
