RESUMO
Objective:To investigate the relationship between base level of Cyfra21-1,SCCA,TK1 and lung cancer prognosis.Methods: A nested case-control study was conducted.721 lung cancer cases who had no distant metastasis were recruited baseline population from January 2010 to January 2013.About 2 years follow-up,364 cases of death or brain (or multiple) metastasis were identified as case group, and the other 357 cases were included in the control group.The level of serum Cyfra21-1,SCCA,TK1 was detected.The relationship between base level of Cyfra21-1,SCCA,TK1 and lung cancer prognosis were analyzed.Results: The age in the case group was (59.3±10.1),and the control group was (59.0±9.9).There were obvious differences in body mass index,smoking index,pathological type,clinical stage,lymph node metastasis and with chronic diseases between case group and control group(P0.05).There were differences in the base level of Cyfra21-1,SCCA,TK1;and there were differences in Cyfra21-1,SCCA,TK1 distribution between case group and control group(P0.05) in patients with different stages of lung cancer.There were differences in the base levels of Cyfra21-1 and SCCA(P0.05) in patients with different pathological types of lung cancer.Logistic regression analysis results showed that the OR value of SCCA,TK1 with lung cancer prognosis were respective 7.235(1.674-14.613),5.009(0.973-10.778),5.816(0.879-16.235).Conclusion: The baseline level of Cyfra21-1 can reflect the prognosis of lung cancer patients,while SCCA,TK1 not.
RESUMO
Objective To observe the influence of phentolamine on N terminal B-type natriuretic peptide precursor(NT-proBNP),blood gas analysis,hypersensitive c-reactive protein and plasma D-dimer in patients with chronic cor pulmonale Methods One hundred and one cases patients with chronic cor pulmonale were randomly divided into two groups,51 patients in the treatment group,50 patients in the control group.All patients were treated with normal anti-infection,eliminating phlegm to smooth wheezing antithrombotic for one week,as the same time patients in the treatment group were treated with phentolamine for one week.Through observed the treatment effect of phentolamine to chronic cor pulmonale,the level of NT-proBNP,blood gas analysis,hypersensitive c-reactive protein and plasma D-dimer in patients with chronic cor pulmonale before and after the treatment were analyzed.Results Compared with before treatment,the levels of NT-proBNP,PCO2,hypersensitive c-reactive protein,plasma D dimer were lower than after one week in two groups,while the level of PO2 was higher.Treatment group:NT-proBNP (1 712.76±572.32) ng/L vs.(271.59±163.05) ng/L,t=20.42,P<0.05,PCO2 (66.34±5.81) mmHg vs.(52.58±5.82) mmHg,t=16.46,P<0.05,PO2 (59.28±6.13) mmHg vs.(73.64±6.10) mmHg,t=23.02,P<0.05,hypersensitive c-reactive protein 86.0(28.0) mg/L vs.23.0(12.0) mg/L,Z=-6.22,P<0.05 mg/L,plasma D-dimer (4 953.37±1 654.09) μg/L vs.(1 847.90±838.66) μg/L,t=17.11,P<0.05.Control group:NT-proBNP (1 527.24±658.70) ng/L vs.(612.58±357.59) ng/L,t=14.52,P<0.05,PCO2 (65.41±5.23) mmHg vs.(56.46±5.65) mmHg,t=13.04,P<0.05,PO2(60.57±5.84) mmHg vs.(67.21±5.19) mmHg,t=-10.06,P<0.05,hypersensitive c-reactive protein 79.0(29.0) mg/L vs.43.0(20.0) mg/L,Z=-6.16,,P<0.05,plasma D-dimer (4 408.02±1 682.83) μg/L vs.(2 598.28±1 242.73) μg/L,t=12.15,P<0.05.But the levels of NT-proBNP,PCO2,hypersensitive c-reactive protein and plasma D-dimer reduced significantly,the level of PO2 increased more significantly in treatment group(t(z)=-6.19,-3.39,-7.16,-3.56,5.70,all P<0.05).Conclusion Phentolamine can reduce the level of NT-proBNP,PCO2,hypersensitive c-reactive protein and plasma D-dimer and increased the level of PO2 in patients with chronic cor pulmonale.Phentolamine combined with routine treatment can improve the clinical efficacy of patients with chronic cor pulmonale.
RESUMO
Objective To explore the effects of Shenfu injection combined with low-dose hydrocortisone on plasma lev?els of human leukocyte antigen (HLA)-DR and procalcitonin (PCT) in patients with septic multiple organ dysfunction syn?drome. Methods A total of 118 patients with septic multiple organ dysfunction syndrome were divided into three groups:control group (n=39), experimental group 1 (n=39) and experimental group 2 (n=40). The control group received conventioanl medicine therapy, while the experimental group 1 received Shenfu injection (100 mL, 2/d, for 7 d) combined with conventio?anl medicine therapy, and the experimental group 2 received Shenfu injection combined with low-dose hydrocortisone (200 mg/d, for 14 d) besides conventional medicine therapy. The peripheral blood samples were collected for the detection of HLA-DR, PCT and lipoperoxide (LPO) before treatment, 1 d, 3 d amd 7 d after treatment. The mortality in 14 d was record?ed. Results The mortality rates in 14 d were 61.5%(24/39), 41.0%(16/39) and 25.0%(10/40) for control group, experimen?tal group 1 and experimental group 2 (χ2=8.15, P0.05). The plasma levels of PCT and LPO were significantly decreased in control group, experimental group 1 and experimental group 2 after 3-d and 7-d treatment, but the levels of HLA-DR was significantly increased (P < 0.05). Conclusion The combination therapy of Shenfu injection and low-dose hydrocortisone can effectively reduce PCT level and increase HLA-DR level, which promotes the improve?ment of patients with septic multiple organ dysfunction syndrome.
RESUMO
OBJECTIVE@#To investigate the mechanism of the pulmonary injury in rats caused by chronic intermittent hypoxia (CIH) and to investigate the intervention effect of Edaravone.@*METHOD@#Ninety-six male Wistar rats were divided into four groups randomly: the control group (NC), chronic intermittent hypoxia group (CIH), chronic intermittent hypoxia normal saline matched group (NS), chronic intermittent hypoxia edaravone treatment group (NE). The four groups were also divided into 1, 2, 3, 4 W time subgroups, and each time subgroup had 6 rats. After the experiment, sections of pulmonary were stained with hematoxylin-eosin (HE) and the level of SOD, MDA, PO2 and Ang II mRNA in rat homogenate pulmonary were measured.@*RESULT@#Pulmonary histology revealed that the CIH group showed high levels of interstitial edema, alveolar atelectasis, inflammatory cell infiltration of alveolar epithelial cell, pulmonary injury were serious in 1, 2, 3, 4 W. But the pulmonary histology of the UC group and the NS group was normal. Compared with the NS group, pulmonary injury of NE group 1, 2, 3, 4 W, significantly decreased. Compared with the NC group, the levels of PO2 in the CIH group were decreased; while the compared with the NS group, the levels of PO2 in the NE group were increased. Compared with the UC group and NS group, the levels of Ang II mRNA in each time point in CIH group were increased gradually (P < 0.05), the content of MDA were increased in 1, 2, 3, 4 W (P < 0.05), they had reached the peak all at 4 W; while the SOD in each time point in CIH group were decreased gradually (P < 0.05) compared with that in UC group and NS group; The Ang II mRNA levels of CIH in pulmonary showed positive correlation with MDA [r = 0.782,P < 0.01]; while the Ang II mRNA levels of CIH in pulmonary showed negative correlation with SOD [r = - 0.904, P < 0.01].@*CONCLUSION@#CIH can cause pulmonary injury through oxidative stress and activating Ang II, and Edaravone could prevent pulmonary injury induced by CIH through scavenging oxygen free radicals.
