ABSTRACT

Objective:To investigate the changes and clinical significance of prothrombin time (PT) during chemotherapy for non-Hodgkin lymphoma (NHL) in high-altitude area and low-altitude area, and understand the relationship between NHL and PT.Methods:From August 2018 to September 2019, data of 68 cases of NHL patients in the Fifth People′s Hospital of Qinghai Province in the high-altitude area (average altitude: 2 261 m) and the Tianjin Fourth Central Hospital in the low-altitude area (average altitude: 1.3 m) were collected and compared with those of 20 subjects from health examination. The patients were divided into groups according to the NHL classification, stage and grade (international prognostic index, IPI score), the PT at initial diagnosis was compared. The PT changes before and after chemotherapy (6 cycles) were compared between high-altitude area and low-altitude area.Results:The PT in healthy subjects and PT at initial diagnosis in NHL patients in low-altitude area were lower than those in high-altitude area: (12.3 ± 1.3) s vs. (13.4 ± 1.9) s, (12.2 ± 0.8) s vs. (13.7 ± 1.1) s, and there was statistical difference ( P<0.05). There was no significant difference between NHL patients and healthy patients in the same area ( P>0.05). In NHL patients in high-altitude area and low-altitude area, PT of different NHL classification, stage and grade were statistically significant ( t = 4.611, 8.202, 6.893, 5.345, 3.121, 5.397, 2.838 and 3.720, P<0.05). In the same altitude area, NHL classification, stage and grade of NHL patients had no significant effect on PT, and there were no statistically significant difference ( P> 0.05); in NHL patients, there were statistically significant differences in PT before and after chemotherapy between high-altitude area and low-altitude area: (13.7 ± 1.1) s vs. (12.2 ± 0.8) s, (13.4 ± 1.4) s vs. (12.0 ± 1.3) s, and there were statistical differences ( P<0.05), and no significant changes in PT before and after chemotherapy in the same altitude area ( t = 1.377 and -1.222, P>0.05). Conclusions:PT of NHL patients in low-altitude area is lower than that in high-altitude area, and there is no significant correlation with NHL classification, stage, grade and chemotherapy in NHL patients.

ABSTRACT

Objective To investigate the clinic and microbial characteristic of fever along with agranulocy-tosis in patients with malignant hematopathy. Methods Retrospective study was carried out on patients with malig-nant hematopathy who developed agranulocytosis during hospitalization. Results A total of 512 febrile events occurred. Duration of agranulocytosis,severe agranulocytosis,poor physical condition,previous exposure to broad-spectium antibiotics and central venous catheterization were correlated with higher incidence of febrile event. There are 328 cases(64.06%)with definite infected sites and 184 cases(35.94%)with fever of unknown origin(FUO). Gram-negative bacterium was most common(64.35%),followed by Gram-positive bacterium(23.61%)and fungus (12.04%). 57 cases resistant bacteria were detected. Mortality incidence resulting from pulmonary infection was higher than that from FUO(P 0.25)or between blood stream infection and FUO(P>0.1). Conclusions Many factors were corre-lated with incidence of fever along with agranulocytosis in patients with malignant hematopathy. Gram-negative bacte-rium was most common pathogenic microorganism,followed by Gram-positive bacterium,all of which manifested high drug resistance rate. Understanding the epidemiological trend will be beneficial for clinic treatment.

ABSTRACT

Objective To investigate the tumor-inhibitory effect of cytokine-induced killer cells(CIK)co-cul-tured with dendritic cells (DC)pulsed by breast cancer stem cell antigen on the same tumor-bearing mice. Methods Breast cancer stem cells were isolated from the cell line of MCF-7/ADR and extract lyses antigen of the stem cell was saved. DC and CIK derived from peripheral blood mononuclear cells of healthy individuals were co-cultured and pulsed or un-pulsed by the above antigen lyses. This DC+CIK were injected to breast tumorbearing mice (BCSC-AP-DC+CIK group), and were used to compared with the common breast cancer cell antigen (rather than breast cancer stem cell antigen) pulsed DC+CIK group(AP-DC+CIK group), DC+CIK group, CIK CIK group and normal saline group(NS group). The tumor-inhibitory effect were evaluated and compared among all 5 groups through the tumor size, TdT-mediated dUTP nick end labeling test (TUNEL), examining expression level of bcl-2 and bax by immunohistochemistry. Results The tumor size in each group before and after therapy and the tumor size after therapy between each group was of significant difference(P<0.05). The maximum size is NS group(3.625±0.093)cm3 and BCSC-AP-DC+CIK group is minimum,which is (1.234±0.131)cm3. BC-SC-AP-DC+CIK group is of highest expression of bax and apoptotic index value, lowest bcl-2 expression in all 5 groups. Conclusion The CIK co-cultured with DC pulsed breast cancer stem cell antigen was more effective to induce apoptosis of breast cancer cells than those of CIK cells co-cultured with DC pulsed breast cancer cell antigen,CIK cells co-cultured with DC and CIK cells.
