ABSTRACT

Objective To explore the expression of FOXM1 in non-small cell lung cancer(NSCLC) and the relationship between FOXM1 expression and the clinical pathological factors,clinical response to target-therapy in NSCLC remained unknown.Methods A total of 80 NSCLC patients were recruited into this study,FOXM1 expression was assessed by immunohistochemistry and analyzed with the clinical pathological factors and clinical response to target-therapy.Results The positive rate of FOXM1 expression was 41.25%.The positive expression of FOXM1 had no significant difference in patients with different age,gender,cancer staging,smoking history(P>0.05),but had significant difference in patients with different degree of differentiation,lymph node metastasis(P<0.05).Survival time in patients with positive FOXM1 expression was significant shorter than that with negative FOXM1 expression(P<0.05).Conclusion The expression of FOXM1 closely correlated with patients histological differentiation,lymph node metastasis,progress-free survival time in patients with positive FOXM1 expression was significantly shorter than those with negative FOXM1 expression.

ABSTRACT

Objective To investigate the expression characteristics of T lymphocyte subsets in peripheral blood of patients with newly diagnosed multiple myeloma(MM),as well as the equilibrium relationship between the ratio of helper T cells 17(Thl7)and CD4+CD25+Foxp3+regulatory T cells(Treg cells),and analyze their clinical significance in the pathogenesis of MM.Methods The proportion of CD3+,CD3+CD4+,CD3+CD8+cells,Th17 cells,Treg cells in peripheral blood and the ratios of CD3+CD4+/CD3+CD8+、Th17/Treg were analyzed between the 30 patients with MM in newly diagnosed and 20 healthy volunteers(control group),then analysis the differences between MM patients and control group.In 30 cases of newly diagnosed MM patients(patient group)and 20 healthy volunteers(control group),total T cells in peripheral blood(CD3+),auxiliary T cells /induced T cells(CD3+CD4+),the inhibitory T cell /cytotoxic T cells(CD3+CD8+),the ratio of(CD3+CD4)/(CD3+CD8+),the percentages of Th17 cells and Treg cell and the ratio of Thl7 and Treg were detected,and the differences between MM patients and control group were compared.Results The ratio of inhibition/cytotoxic T cells(CD3+CD8+)in the patient group was higher than that in the control group(P<0.05).(CD3+CD4+)/(CD3+CD8+)ratio in the patient group was lower than that in the control group(P<0.05);in the patient group,the ratio of Th17 cells in peripheral blood of patients was(5.9 ± 1.9)%,which was increased compared with the control group(4.0 ± 0.9)%(P<0.05);the ratio of Treg cells in the patient group was(1.2 ± 0.3)%,which was decreased com-pared with the control group(2.1 ± 0.4%)(P< 0.05);and the ratio of Th17/Treg cells was significantly higher in the patient group,and the difference was statistically significant(P<0.05).Conclusion Peripheral blood T cell subsets disorder exists in pa-tients with MM,Thl7/Treg cell imbalance caused by the increase of Thl7 cell ratio and the decrease of the ratio of Treg cells,and the imbalance of immune system may play a role in the occurrence and development of MM,and has some guiding value for the prognosis.

ABSTRACT

Objective To discuss the diagnostic value of soluble scavenger receptor(sCD163)for the patients of malignant tumor associated with fever in early infection .Methods Collect 102 cases of patients confirmed with malignant tumor in this hospi-tal since January to December 2014 ,all the patients were examined with blood culture .102 patients were divided into two groups ac-cording to the results of blood culture :infection group (60 cases) and uninfected group (42 cases) .ELISA ,electrochemical lumines-cence and immune transmission turbidimetric methods were used to detect the levels of sCD163 ,PCT and CRP in serum ,to compare the differences in the above indicators between two groups .The receiver-operating characteristic curve (ROC curve) was applied to evaluate the application value of sCD163 in diagnosing of malignant tumor associated with fever in early infection .Results The lev-el of sCD163 ,PCT and CRP had statistically difference in two groups(P< 0 .05) ;the critical values of sCD163 、PCT and CRP were 110 .80 ng/mL ,0 .45 ng/mL ,15 .60 mg/L respectively which can suggest the patients with malignant tumor complicated with fever in early infection .The area under the curve were 0 .894 ,0 .835 ,0 .743 respectively ,among that sCD163 area was the largest ;The corresponding sensitivity were 88 .9% ,77 .9% and 88 .0% ;specificity were 77 .0% ,74 .0% and 50 .0% respectively .Conclusion Compared with PCT ,CRP ,sCD163 has more value for diagnosing the patients of malignant tumor associated with fever in early in-fection .

ABSTRACT

Objective To explore the value of combined detection of bone marrow smear(BMS) and flow cytometry(FCM) to examine bone marrow involvement(BMI)of B cell non‐Hodgkin′s lymphoma(B‐NHL) .Methods Patients with B‐NHL were detec‐ted by BMS and FCM simultaneously .Smears were stained with Wright‐Giemsa′s staining to differentially count neoplastic cells and the processed sample with fluorescent staining for the FCM .Results 93 cases of patients with B‐NHL were detected .The detection rate of BMS and FCM were 11 .8% and 29 .0% .There was statistical difference of detection rate between the two method(P<0 .05) .In 11 cases patients of BMI with the method of BMS ,while using the method of FCM 10 cases were positive .Conclusion Both BMS and FCM are useful to diagnose BMI of B‐NHL ,each of them has individual characteristics .Combined detection of these two methods can increase the diagnostic of BMI .

ABSTRACT

Objective To investigate peripheral blood T lymphocyte subsets and NK cells changes in the diffuse large B cell lymphoma (DLBCL) patients before and after chemotherapy,and analyse the relationship between the results and treatment.Methods Collect the 47 patients venous blood of the effective treatment DLBCL by pathology.T lymphocyte subsets and NK cells were determined by flow cytometric.Analyse the results statistically significant difference before treatment,the second chemotherapy cycle and the fourth chenmotherapy cycle compared with 50 healthy control persons.Results The levels of CD3+,CD4+,CD4+/CD8+ NK cells in DLBCL patients before chemotherapy [(70.04±8.87)%,(42.79±6.06)%,(1.68±0.59)%,(14.40±6.02)%]were lower than healthy controls [(63.89±6.67)%,(32.72±5.77)%,(0.85±0.25)%,(9.95±5.24)%](P < 0.05),and the level of CD8+ cells is higher than the healthy controls [(27.21 ±6.54)% vs.(39.92±7.11)%](P < 0.05).The levels of CD3+,CD4+,CD4+/CD8+ cells had significant difference between the second and the fourth chemotherapy cycle in DLBCL patients (P < 0.05).The levels of CD3+,CD4+,CD8+,CD4+/CD8+,NK cells had significant difference between the fourth chemotherapy cycle DLBCL patients and the DLBCL patients before chemotherapy (P < 0.05).Conclusion The DLBCL patients exist immunosuppression before chemotherapy.Peripheral T lymphocyte subsets and NK cells can be used as good reflect of the cellular immune function in DLBCL patients.Clinical parameters can be used for the immune function monitoring and providing guidance for the treatment options.
