ABSTRACT
Objective:To explore the effect of ICE regimen (ifosfamide, carboplatin, VP16) combined with methotrexate on the clinical efficacy and expression of miR-451a and miR-15a in patients with diffuse large B cell lymphoma (DLBCL).Methods:A total of 56 patients with DLBCL in the Third Hospital of Changsha from March 2013 to may 2018 were prospectively selected and randomly divided into observation group and control group, 28 cases in each group. The control group was treated with ICE regimen, and the observation group was treated with ICE regimen combined with methotrexate. The tumor control rate, toxic and side effects, the expression of miR-451a and miR-15a, immune function (CD3 +, CD4 +, CD8 +, CD4 +/CD8 +), serum tumor markers [β 2 microglobulin (β 2-MG), carbohydrate antigen 125 (CA125), and lactate dehydrogenase (LDH)] levels were compared before and after treatment between the two groups, follow-up for 6 to 12 months was used to calculate the survival rate of the two groups. Results:The tumor control rate in the observation group (92.86%) was higher than that in the control group (71.43%) ( P<0.05); After treatment, the miR-15a decreased and miR-451a increased in the two groups, and the miR-15a in the observation group was lower than that in the control group, while miR-451a was higher than that in the control group ( P<0.05); After treatment, the CD3 +, CD4 +, CD4 +/CD8 + of the two groups were lower than before treatment, and CD8 + was higher than before treatment ( P<0.05), but there was no significant difference between the two groups ( P>0.05); After treatment, the serum CA125, LDH, and β 2-MG in the two groups were lower than before treatment, and the above indexes in the observation group were lower than those in the control group ( P<0.05); There was no significant difference between the two groups in the incidence of side effects and the survival rates of 6, 9 and 12 months after treatment ( P>0.05). Conclusions:ICE regimen combined with methotrexate in the treatment of DLBCL can further improve the therapeutic effect and reduce the serum tumor marker levels by regulating the expression of miR-451a and miR-15a, with less toxic side effects and less immune damage, and high safety.
ABSTRACT
Objective:To investigate the changes of plasma prothrombin fragment 1+ 2 (F 1+2), tissue factor positive microparticle (TF+ MP) and thrombin antithrombin complex (TAT) level before and after the treatment of low molecular weight heparin combined with reteplase in patients with malignant tumor and lower extremity venous thrombosis. Methods:From July 2016 to October 2019, 64 patients with malignant tumors and lower extremity venous thrombosis in the Third Hospital of Changsha were selected, they were divided into observation group ( n=32) and control group ( n=32) by simple randomization. The control group was treated with low molecular heparin, and the observation group was treated with low molecular heparin combined with reteplase. The efficacy, clinical symptom improvement time, incidence of adverse reactions, difference in lower limb circumference, blood flow velocity, activated partial thromboplastin time (APTT), prothrombin time (PT), plasma F 1+2, TF+ MP, TAT level before and after treatment were compared between the two groups; the correlations of plasma F 1+2, TF+ MP, and TAT level with clinical symptom improvement time, peripheral diameter difference of lower extremity, blood flow velocity, APTT, and PT were analyzed. Results:The total effective rate of the observation group (87.50%) was higher than that of the control group (65.63%) ( P<0.05); The improvement time of clinical symptoms in the observation group was shorter than that in the control group ( P<0.05); After treatment, the peripheral limb diameter difference of the observation group was lower than that of the control group, and the blood flow velocity was higher than that of the control group ( P<0.05); The APTT and PT in the observation group were higher than those in the control group after treatment ( P<0.05); The plasma F 1+2, TF+ MP, and TAT level in the observation group were lower than those in the control group after treatment ( P<0.05); The levels of plasma F 1+2, TF+ MP, and TAT were positively correlated with symptom improvement time and lower limb circumference difference, and negatively correlated with blood flow velocity, APTT, and PT ( P<0.05); There was no significant difference in the incidence of adverse reactions (18.75%) between the observation group and the control group (12.50%) during the treatment period ( P>0.05). Conclusions:Plasma F 1+2, TF+ MP, and TAT expression in patients with malignant tumors and venous thrombosis of the lower extremity can be used as biological indicators to evaluate the patient's condition and treatment effect. Low molecular weight heparin combined with reteplase can significantly reduce the plasma F 1+2, TF+ MP and TAT level, promote the improvement of symptoms, effectively reduce the peripheral diameter difference of lower extremity, improve blood flow velocity and coagulation function, and has a significant effect.
ABSTRACT
Objective To analyze the effect of Yaotongning capsule in the treatment of lumbar osteoarthritis patients.Methods From March 2013 to March 2015 in our hospital, 80 cases of lumbar osteoarthritis patients according to the digital table method were divided into two groups: the control group and the experimental group.The patients of the control group were given Bitongning, and the patients of the experimental group were given Yaotongning capsule, and the therapeutic effect, serum indexes and Japanese Orthopaedic Association ( JOA ) of two groups were compared. Results The curative effect of the experimental group was higher than control group(95.00%vs.67.50%) , the JOA score of the experimental group was higher than control group [(27.46 ±1.07)points vs.(21.06 ±1.89)points] (P<0.05).After treatment, the MMP-3(65.28 ±4.37) ng/L and IL-1β(12.43 ±1.01) ng/L of the experimental group were significantly lower than MMP-3(79.56 ±5.36) ng/L, IL-1β(16.44 ±1.03) ng/L of the control group, and the difference was significant (P<0.05).Conclusion The lumbar osteoarthritis patients with Yaotongning capsule has obvious effect, and the function of lumbar intervertebral joint improves obviously, and the serum index is normal, safe and reliable.
