ABSTRACT
Objective To detect the expression of Survivin and Caspase-9 gene in Uygur breast cancer pa-tients with different HER-2 phenotypes,to find out the difference and association of the two genes and to find out the potential roles of the two genes breast cancer pathogenesis. Methods We selected 72 Uygur patients diag-nosed as breast cancer initially and they were divided into group A with HER-2 positive(n = 39)and group B with HER-2 negative(n = 33). Another 40 Uygur patients with benign breast were involved as the controls. Immunohis-tochemistry and real-time RT-PCR were used to detect the two genes,and analyze the differences and association of each gene between the groups. Results (1)The expression of Survivin gene in group A and B were higher than that in the control group. Further analysis showed that the expression of Survivin gene was enhanced in group A when compared with that in group B(P < 0.05);while even the expression of Survivin gene in group B was higher than that in the control group but no statistical difference was found(P > 0.05).(2)The expression of Caspase-9 gene in group A and B were lower than that in the control group. Real-time RT-PCR showed that the expression of Caspase-9 gene of group A was decreased when compared with that in group B(P < 0.05);While the expression of Caspase-9 gene of group B was slightly lower that of the control group but it showed no statistical significance (P > 0.05). Immunohistochemical results showed there were no statistical differences of expression of Caspase- 9 gene in group A and B and control group(all P > 0.05). The expression of Survivin and Caspase-9 gene was nega-tively associated in group A and B(P < 0.01;P < 0.05). Conclusions In Uygur patients with HER-2 positive breast cancer,the expression of Survivin gene is enhanced but that of caspase-9 gene is decreased,and they are negatively associated. Through inhabiting caspase-9 gene,Survivin gene may potentially lead to the occurrence of HER-2 positive breast cancer.
ABSTRACT
Objective To explore the experience of diagnosis and surgical treatment of carotid body tumor.Methods A retrospective analysis between November 2008 and November 2015 was proceeded,the clinical data of surgical treatment for 81 patients with carotid body tumor was collected,to analyze data by SPSS19.0,and summarize the diagnosis of carotid body tumor,choice of operation methods and curative effect and complications prevention.Results Seventy-four cases underwent surgery treatment:tumors of 52 cases were simply stripped,tumors of 13 cases were resected combined with ligation of external carotid artery.Tumors of 7 cases were resected with internal and external carotid artery ligation,3 cases of whom underwent artificial blood vessel internal carotid artery end to end anastomosis.Postoperative death in 1 case of acute myocardial infarction,complicated with cerebral infarction in 2 cases,6 cases of injury of cranial nerve relieved after symptomatic treatment.No hemiplegia,aphasia and other serious complications.Tumor size and the surgery time correlation analysis:the correlation coefficient was 0.226,no significant correlation.Conclusions CTA is the most commonly used method of preoperative examination.Surgical resection is an effective method in treatment of carotid body tumor.Prevention injury of carotid artery cr internal carotid or common carotid artery and their reconstruction is the key to a successful operation.Sufficient preoperative assessment,select the appropriate operation method,intraoperative careful performance can ensure the cerebral perfusion,is the key to prevent and reduce the complications.
ABSTRACT
Objective To provide regional anatomical data for clinical application through observing the type, length and diameter of variation in the medial cubital vein of upper limb. Methods Dissected the medial cubital vein of upper limb in 35 (70 sides) adult cadavers (male 38, female 7), and observed the morphological structure. The length and vessel diameter of the medial cubital vein were measured. Results The variation of the medial cubital vein of upper limb was divided into six type. TypeⅠincluded 29 cases (41. 43%) of male and 8 cases (11. 43%) of female;Type Ⅱ included 14 cases (20. 00%) of male and 4 cases (5. 71%) of female;Type Ⅲ included 7 cases (10. 00%) of male and 2 cases (2. 86%) of female;TypeⅣincluded 3 cases (4. 29%) of male and 0 cases of female;TypeⅤincluded 2 cases (2. 86%) of male and 0 cases of female;TypeⅥincluded 1 cases (1. 43%) male and 0 cases of female. Conclusion This study enriched anthropology data of the medial cubital vein and it has the role of guiding in clinical applications.
