ABSTRACT
Objective:To analyze the clinical effect of TREVO stent thrombectomy combined with tirofiban on patients with acute large-artery occlusion of the anterior circulation.Methods:Seventy-two patients with acute large-artery occlusion of the anterior circulation accepted thrombectomy in our hospital from November 2016 to May 2020 were divided into two groups according to different treatment methods: 35 patients in the control group were treated with TREVO stent thrombectomy, and 37 patients in the treatment group were treated with TREVO stent thrombectomy combined with tirofiban via intra-variceal injection. The success rate of recanalization, specific conditions of thrombolysis, improvement degrees of nerve defect, coagulation function, prognoses 90 d after thrombectomy, and complications were compared between the two groups.Results:The success rate of postoperative vascular recanalization in the treatment group and control group was 91.89% (34/37) and 88.57% (31/35), respectively, without statistically significant difference ( P>0.05). The time and times of thrombotomy in the treatment group were significantly shorter/smaller than those in the control group (P<0.05). The National Institute of Health stroke scale (NIHSS) scores of patients from the treatment group 14 d after thrombectomy were significantly lower than those of the control group ( P<0.05). The postoperative thrombin time, prothrombin time, and activated partial thrombin time of the treatment group were significantly longer than those of the control group ( P<0.05). The good prognosis rate of patients in the treatment group and control group 90 d after thrombectomy was 86.49% (32/37) and 60.0% (21/35), with significant differences ( P<0.05); and the incidence of complications was 8.11% (3/37) and 14.29% (5/35), without significant differences ( P>0.05). Conclusion:TREVO stent thrombectomy combined with tirofiban has a significant effect on treatment of acute large-artery occlusion of the anterior circulation, enjoying high safety.
ABSTRACT
Objective To investigate the prognostic significance of proteolysis-inducing factor (PIF) in gastric cancer patients.Methods Biopsies of the rectus abdominis muscle were obtained intra operatively from 53 gastric cancer patients and 53 subjects undergoing surgery for benign abdominal diseases,muscle and serum PIF,ubiquitin expression,and proteasome proteolytic activities were assessed through reverse-transcription polymerase chain reaction (RT-PCR),Western blot,and enzyme-linked immunosorbent assay (ELISA).Results PIF was significantly upregulated in muscle of gastric cancer compared to control muscles.PIF was upregulated in 60％ (32/53) muscle of gastric cancer.Over expression of PIF in muscles of gastric cancer were associated with level of serum albumin,tumor node metastasis (TNM) stage,and percent of weight loss.The survival rate of patients with a high expression of PIF was significantly lower than those in patients with low expression (P ＜ 0.05).Conclusions PIF was significantly upregulated in muscle of gastric cancer,over expression of PIF in muscles of gastric cancer was associated with level of serum albumin,TNM stage,percent of weight loss,and prognosis.PIF might play an important role in progression and prognosis of gastric cancer.
