ABSTRACT
Objective To analysis the efficacy and safety of endovascular graft exclusion for patients with Stanford type B aortic dissection.Methods The clinical data of 46 patients with Stanford type B aortic dissection who received endovascular graft exclusion were analyzed retrospectively.The stents were inserted from the femoral artery to exclude the tear of dissection,and all operation were peformed under digital subtraction angiography (DSA).The operative technique,outcome and complications were observed.Results The stents were successfully performed in all patients.The length of stay in hospital time after operation was 5-20 (12.9 ± 3.4) d.Endo-leak occurred in 2 patients and relieved after re-expanding.Followed up for 2 d to 5.1 years,average 36 months,1 patient got lacunar infarction and 1 patient died after leaving hospital 2 d.The others were free from the serious complications such as aortic dissection and paraplegia.Conclusion Endovascular graft exclusion is safe and effective for the treatment of Stanford type B aortic dissection in hospital and mid-term,and can significantly improve the survival rate and quality of life.
ABSTRACT
Objective To detect the expression of hypoxia inducible factor-lα (HIF-1α) in both mRNA and protein and reactive oxygen species (ROS) levels in human epithelial ovarian cancer,and investigate the abnormal state of oxygen metabolism and their interaction in human epithelial ovarian cancer develoment.Methods The expression of HIF-1α in mRNA and protein in epithelial ovarian cancer were detected by real time reverse transcription-polymerase chain reaction and immunohistochemical Elivision plus two-step method,and the level of ROS was detected by fluorescence microplate reader.Results The relative content of HIF-1α mRNA in the epithelial ovarian cancer group was 4.466±0.754,which was higher than that of the benign control group (6.073±1.053) (t =-7.701,P =0.000).The expression of HIF-1α mRNA was raised gradually in tissues of the benign ovarian tumor,early and advanced stage of epithelial ovarian cancer (t =5.301,P =0.000).The expression of HIF-1α mRNA in the epithelial ovarian cancer had positive correlation with grade and lymph node metastasis (t =3.724,-3.851,P =0.000).The positive expression rate of HIF-1 α protein in epithelial ovarian cancer was 63.49 ％ (40/63),which was higher than that of the benign group (U =433,P =0.005),which had positive correlation with lymph node metastasis and stage (x2 =4.289,12.360; P =0.038,0.000).The expression of ROS in the epithelial ovarian cancer was 110.239±18.414,which was higher than that of the benign group (58.366±20.360) (t =11.068,P =0.000),which had positive correlation with grade,lymph node metastasis and stage (t =-2.055,2.816,-4.138; P =0.044,0.007,0.000).There was a moderate positive correlation between the expression of HIF-1α mRNA and ROS in epithelial ovarian cancer (r =0.572,P =0.000),and that was similar in low differentiation group and advanced group,there was a relatively high positive correlation in lymph node metastasis group (r =0.703,P =0.001),there was a relatively low correlation between HIF-1α mRNA and ROS (r =0.376,P =0.002).Conclusion Hypoxia is the basic characteristic of human epithelial ovarian carcers.This study suggested that HIF-1α is associated with human epithelial overaian cancer prognosis.ROS and HIF-1α might be involved in the genesis of human epithelial ovarian cancer,and the regulation of ROS to HIF-1α may play the important roles in the invasion and metastasis process of human epithelial ovarian cancer.The expression of HIF-1α is regulated by ROS at the transcriptional and protein levels,probably mainly on protein level.
ABSTRACT
Objective To investigate the expression of Golgi phosphoprotein 3 (GOLPH3) at protein and mRNA levels in serous epitheial ovarian carcinoma and its significance.Methods The expression of GOLPH3 at protein and mRNA levels were evaluaed by Western blot and Real time RT-PCR,respectively,in 42 cases of serous epithelium ovarian carcinoma,14 cases of benign serous ovarian tumors and 7 cases of normal ovarian epithelium tissues.Results GOLPH3 mRNA was significantly higher from 2.97 to 7.04 fold in ovarian serous cystadenocarcinoma tissues compared with ovarian serous carcinoma tissues (P ＜ 0.05).There was no positive expression of GOLPH3 protein in normal ovarian epithelium tissues.GOLPH3 protein positive expression rate was higher in ovarian serous cystadenocarcinoma (73.81 ％) than that in ovarian serous carcinoma (35.71％) (P ＜ 0.01).GOLPH3 protein was correlated with the pathologic differentiation (P =0.019),the FIGO stage (P =0.042),and lymphatic metastasis (P =0.000),but was not associated with age (P =0,881).The positive rate and overexpression of GOLPH3 in poor differentiated grade group were higher than that in well and middle differentiated grade group (P ＜ 0.05).Conclusions GOLPH3 may play an important role on the development of ovarian serous cystadenocarcinoma,and may be a potential target of gene therapy.
ABSTRACT
Objective To summarize the experience in the diagnosis and surgical treatment of pulmonary sequestration. Method The clinical data from 15 patients with pulmonary sequestration underwent surgical operation from July 2000 to January 2009 were reviewed and analyzed retrospectively. Results Pulmonary sequestration was diagnosed in 14 patients before the operation with the diagnosis rate of 93.33% (14 /15).Preoperation plane and contrast chest CT scan were performed in all cases,and 9 patients performed angiography reconstruction. Twelve patients with intralobar sequestration underwent lobectomy and 3 patients with extralobular sequestration underwent local lesion resection. Abnormal supply arteries were intraoperatively found in 14 patients originating from the thoracic main artery, 1 patient from the eeliac artery. Smooth recovery was achieved in all patients. No perioperarive death occurred. Conclusions Pulmonary sequestration is a rare disease with high misdiagnosis rate in some patients. Contrast enhanced CT scan and angiography may improve the diagnosis of pulmonary sequestration. Operation is a safe and effective method for the treatment of pulmonary sequestration.
