Objective The expression of Ang-2 and HSP90α in serum of patients with non-small cell lung cancer and their correlation with TNM staging were analyzed.Methods From January 2015 to June 2016,40 patients with elderly non-small cell lung cancer and 40 healthy persons were selected as the study subjects.The serum levels of Ang-2 and HSP90 alpha in the subjects were examined and their correlation with the TNM stage of the patients was analyzed.Results Observation of Ang-2 and HSP90α levels in the serum of the patients group were significantly higher than the control group,and the difference was statistical significance(P<0.05);Serum Ang-2 and HSP90α levels TNM Ⅰ-Ⅱ patients were significantly lower than that of stage Ⅲ and Ⅳ,the difference was statistical significance(P<0.05);Serum Ang-2 and HSP90α levels in TNM Ⅲ patients was significantly lower than those in stage Ⅲ and Ⅳ,the difference was statistical significance(P<0.05);TNM staging was positively correlated with the levels of HSP90α in serum,and statistical significance(r=0.425,P<0.05),TNM stage had a remarkably positive correlation with the level of Ang in serum(r=0.525,P<0.05).Conclusion The levels of Ang-2 and HSP90α were significantly higher in the serum of elderly patients with non-small cell lung cancer,and the expression level was positively correlated with TNM stage.

Objective To discuss factors related to clinical characteristics,biological behavior,and prognosis in gastric stromal tumors (GST).Methods We retrospectively analyzed clinical materials and records of 70 GST patients diagnosed after surgery and pathological examinations,all patients were contacted by telephone or mail for follow-up.Results (1) All GST patients had similar distribution of gender,and had age range of 50 to 69 years with mean age of 59.1 years.Clinical symptoms were non-specific,and main clinical manifestations included abdominal discomfort (42.9％),followed by abdominal pain (37.1％),and upper digestive tract hemorrhage (7.1％).(2) Sex,age,presenting symptoms,and original location of tumors were not significantly related to prognosis (P ＞ 0.05).However,size of the tumor,mitosis count,and the malignancy potential grading were significantly associated with patient prognosis.Among them,size of the tumor (maximum tumor diameter ＞ 5 cm vs ＜ 2 cm,HR =21.3,95％ CI:5.9-77.0;maximum tumor diameter 2-5 cm vs ＜ 2 cm,HR =2.3,95％ CI:1.2-7.8),and mitosis count (mitosis count ＞ 10/50 HPF vs mitosis count ≤5/50 HPF,HR =22.5,95％ CI:8.6-58.6;6-10/50 HPF vs ≤5/50 HPF,HR =11.1,95％ CI:9.9-12.3) were independently associated with GST prognosis.Conclusions Tumor size,mitosis count,and malignancy potential grading were associated with prognosis of GST.Among them,tumor size and mitosis count were independent predictors of prognosis.When the tumor size is larger,and mitotic count and the malignant potential grade is higher,prognosis of GST patients were worse.
