Objective:To compare the simplicity, safety, efficacy, prognoses and economic burden of CAS-R-2 frameless stereotactic device and Leksell frame stereotactic device in assisting surgery for patients with hypertensive cerebral hemorrhage (ICH, hematoma volume: 20-40 mL).Methods:The clinical data of 120 patients with supratentorial ICH, admitted to our hospital from December 2012 to December 2019, were retrospectively analyzed; trepanation and drainage assisted by CAS-R-2 frameless stereotactic device was performed in 65 patients (frameless group), and trepanation and drainage assisted by Leksell frame stereotactic device was performed in 55 patients (frame group). The differences of surgery time, hematoma evacuation rate 7 d after surgery, incidences of recurrent hemorrhage and intracranial infection during hospitalization, length and expense of hospitalization, and modified Rankin scale (mRs) scores 6 months after surgery were compared between the two groups.Results:As compared with those in the frame group, patients from the frameless group had significantly shorter surgery time ([0.5±0.1] h vs. [2.2±0.5] h), significantly lower incidence of recurrent hemorrhage (0% vs. 9.1%) and significantly lower incidence of intracranial infection (1.5% vs. 9.1%) during hospitalization ( P<0.05). The hospitalization expense of patients from the frame group was significantly lower than that in the frameless group ( P<0.05). There were no significant differences in hematoma evacuation rate 7 d after surgery, length of hospital stays, and mortality and mRs scores 6 months after treatment between the two groups ( P>0.05). Conclusion:For patients with supratentorial ICH, trepanation and drainage assisted by CAS-R-2 frameless stereotactic device has the same curative effect and prognoses as Leksell frame stereotactic one; the former has higher simplicity and clinical safety, and the latter has lower economic burden.
摘要
To analyze the clinical significance of COX-2, GLUT-1 and VEGF expressions in endometrial cancer tissues. One hundred and eight tissue samples from the patients with endometrial cancer enrolled in our hospital from August 2011 to July 2014 were selected, including 60 normal tissue samples [normal group], 60 neoplastic tissue samples [neoplastic group] and 60 cancer tissue samples [cancer group]. All the samples were subjected to immunohistochemical assay to detect the expressions of COX-2, GLUT-1 and VEGF. The clinical data were also investigated for correlation analysis. The positive rates of COX-2 in normal group, neoplastic group and cancer groups were 3.3%, 21.7% and 55.0% respectively. The positive rates of GLUT-1 in normal group, neoplastic group and cancer groups were 3.3%, 25.0% and 70.0% respectively. The positive rates of VEGF in normal group, neoplastic group and cancer groups were 1.7%, 23.3% and 63.3% respectively. With increasing stage of such cancer, decreasing degree of differentiation and lymphatic metastasis, the positive expression rates of COX-2, GLUT-1 and VEGF proteins were raised significantly [P<0.05]. Spearman's correlation analysis showed that the expressions of COX-2 and GLUT-1 [r=0.207, P<0.05], COX-2 and VEGF [r=0.243, P<0.05], as well as GLUT-1 and VEGF [r=0.758, P<0.05] were positively correlated. COX-2, GLUT-1 and VEGF were highly prominent in endometrial cancer, especially in the patients with low degree of differentiation, late stage and metastasis. They functioned synergistically in the onset and progression of this cancer
