RESUMO
Objective:To investigate the expression of fibrinogen-like protein 1 (FGL1) in clear cell renal cell carcinoma (ccRCC) and its correlation with clinicopathological characteristics of patients with ccRCC.Methods:The clinicopathological data of 242 patients with ccRCC who were diagnosed and treated surgically from January 2015 to December 2018 were retrospectively analyzed. The cancerous tissues and paracancerous tissues (2 cm away from the edge of cancerous tissues) of patients were collected. The expression of FGL1 protein was detected by using immunohistochemistry, and the relative expression level of FGL1 mRNA was detected by using reverse transcription polymerase chain reaction (RT-PCR). Cox proportional risk model was used to make univariate and multivariate analysis of the influencing factors of progression-free survival (PFS).Results:The positive rate of FGL1 protein in ccRCC tissues was higher than that in paracancerous tissues [28.5% (69/242) vs. 2.1% (5/242)], and the difference was statistically significant ( χ2 = 65.34, P < 0.001); the relative expression level of FGL1 mRNA in ccRCC tissues was higher than that in paracancerous tissues (1.67±0.12 vs. 0.60±0.15), and the difference was statistically significant ( t = 25.33, P < 0.001). The expression of FGL1 was positively correlated with pathological staging ( r = 0.164, P = 0.011), renal vascular tumor thrombus ( r = 0.130, P = 0.043), regional lymph node metastasis ( r = 0.153, P = 0.018), and distant metastasis ( r = 0.160, P = 0.012). Univariate analysis showed that the tumor diameter, regional lymph nodes metastasis, pathological staging, distant metastasis, and FGL1 expression were factors influencing the PFS of ccRCC patients (all P < 0.05). Multivariate regression results showed that high expression of FGL1 ( HR = 11.679, 95% CI 7.432-15.673, P = 0.015), pathological staging of Ⅲ-Ⅳ ( HR = 13.654, 95% CI 8.765-18.761, P = 0.013), and distant metastasis ( HR = 11.387, 95% CI 7.662-14.831, P = 0.038) were independent risk factors for PFS in patients. Conclusions:FGL1 is highly expressed in ccRCC, which is correlated with pathological staging, renal vascular tumor thrombus, regional lymph nodes metastasis, and distant metastasis. The high expression of FGL1 is a risk factor affecting the prognosis of patients with ccRCC.
RESUMO
Objective:To evaluate the changes of the left atrial systolic function in patients with acute myocardial infarction(AMI)using quantitative tissue velocity imaging(QTVI).Methods:The systolic velocities of the middle of left atrial lateral wall,anterior wall,inferior wall and atrial septum were measured with QTV1 in 45 patients with AMI.The left atrial volume and active atrial emptying fraction(AA-EF)were measured using single-plane Simpson method.Results:(1)Compared with the control group(30 normal subjects),the diameter and volume of the left atrium,as well as AA-EF,increased obviously in patients with AMI(P ＜ 0.01).(2)Compared with the control group,the systolic velocities of the middle of left atrial lateral wall,anterior wall,inferior wall and atrial septum,as well as the average value,increased significantly in patients with AMI (P ＜ 0.05 or P ＜ 0.01).In addition,the average value of left atrial systolic velocity was closely correlated with AA-EF(r=-0.906,tr=14.001,P ＜ 0.01).Conclusion:QTVI could be used to evaluate the left atrial systolic function accurately in patients with AMI.
RESUMO
Objective:To investigate the changes of left ventricular mass index(LVMI),plasma brain natriuretic peptide (BNP),interJeukin-6(IL-6)and interleukin-10(IL-10)in patients with congestive heart failure(CHF),and their values in risk stratification and prognostic evaluation of CHF thereof.Methods:Ninety-five patients with CHF in accordance with 2001ACC/AHA guidelines were enrolled and stratified as stage A(n=21),B(n=23),C(n=31)and D(n=20).The levels of plasma BNP,IL-6 and IL-10 were measured and compaired with those in 20 healthy subjects(control group).The patients were followed up every three months in two years.The end point was the rehospitalization and the cardiac death.Results:(1)The level of LVMI increased early in patients with CHF at stage B.(2)The plasma BNP levels were initially elevated in CHF patients at stage B,and the concentrations of BNP closely paralleled disease severity.(3)The levels of plasma IL-6 and IL-10 were increased,and the ratio of IL-10/IL-6 was decreased,with the progression of CHF at stage C and D.The plasma BNP level was positively correlated with the levels of IL-6 and IL-10.(4)The new CHF stratification was surperior to NYHA functional classification in regard to CHF prognosis prediction.(5)Multivariate COX regression analysis showed the levels of BNP and IL-6 were the independent risk factors in prognostic evaluation(P＜0.01,P=0.026).(6)Patients in high-risk groups stratified by the combination of BNP and stage classification had obviously higher end point events rate.Conclusion:(1)LVMI was a better marker for the evaluation of left ventrieular remodeling.(2)The intrinsic mechanism of CHF progression was inflammatory reaction deterioration.(3)BNP was a good marker in predicting onset and prognosis of CHF.The combination of BNP and the stage classification could improve the prognostic evaluation in patients with CHF.
RESUMO
Objective To improve level of first-aid treatment of severe head trauma and reduce fa-tality. Methods Clinical nursing procedures were applied to patients.Patients need first-aid treatment (105 cases) were divided into the control group(50 cases) and the experimental group(55 cases).The con-trol group adopted routine first-aid procedure,the experimental group was given first-aid nursing with self-designed shortcut nursing procedure for severe head trauma.The effect of application of shortcut nursing procedure was observed by comparing the fatality and time consumption of first-aid treatment between the two groups. Results The fatality and time consumption of first-aid treatment in the experimental groupwas lower than that of the control group, P<0.05. Conclusions Application of shortcut nursing proce-dure in first-aid treatment can not only improve level of first-aid treatment and reduce fatality, but also can instruct nurses how to rescue patients and improve their professional and vocational level.
