Objective To explore the influence of different biological sources of thromboplastin reagent on prothrombin time (PT) detection .Methods The thromboplastin reagents sourced from the rabbit brain extract provided by the Shanghai Taiyang Bi‐ological Technology Co .,Ltd .and Shanghai Changdao Biological Technology Co .,Ltd .and recombination tissue factor were selected and used for detecting PT in the non‐Warfarin treatment group(group A ,38 cases) and the Warfarin group(group B ,43 cases) by the Sysmex CA7000 blood coagulation analyzer .The detection results from different sources of prothrombin reagents were com‐pared between the two groups and performed the statistical analysis .Results In the group A ,the detection results had no statistical differences among the reagent R1 ,R2 ,R3 and R4 (F=3 .42 ,P>0 .05 ,n=38);in the group B ,the detection results had statistical differences among the reagent R1 ,R2 ,R3 and R4 (F=57 .68 ,P<0 .05 ,n=43) ,while the detection results had no statistical differ‐ences between reagent R1 and R3(t=2 .21 ,P>0 .05) and between reagent R2 and R4(t=2 .09 ,P>0 .05) .Conclusion The detec‐tion results of PT by different sources of PT reagent in the non‐Warfarin treatment patients demonstrate no significant difference , but the detection results in the Warfarin treatment patients have highly significant difference;the recombination tissue factor throm‐boplastin reagent has higher sensitivity ,which used for monitoring PT in the warfarin treated patients should establish a new thera‐peutic standard value for avoiding to cause the misdiagnosis and mistreatment .

Objective:To investigate the clinical efficacy of postoperative radiotherapy combined with compound matrine injection on the patients with breast cancer.Methods:Eighty-three patients with breast cancer received breast-conserving and sentinel lymph node biopsy before the study who were admitted in our hospital were divided into the control group and observation group.Forty-two patients in control group were treated with postoperative radiotherapy,and forty-one patients in observation group were received postoperative radiotherapy combined with compound matrine injection.The CA125,CA153,CA724,levels of CD3+,CD4+,CD8+,CD4+/CD8+,NK,and adverse reaction in the two groups were detected and compared.Results:After treatment,the CA125,CA153,and CA724 in both groups were obviously decreased (P＜0.05),which were significantly lower in the observation group than those of the control group (P＜0.05).CD3+,CD4+,CD8+,CD4+/CD8+,and NK cell in the observation group showed remarkable improvement (P＜0.05) compared with those before treatment.And CD3+,CD4+,CD4+/CD8+,and NK cell of the observation group were significantly higher than those of the control group,while CD8+ was much lower (P＜0.05).During the treatment period,the incidence of skin reaction over grade Ⅱ,and myelosuppression in observation group were much lower than those of control group (P＜0.05).Conclusion:Postoperative radiotherapy combined with compound matrine injection had good ability in enhancing the cellular immune function and reducing adverse reaction on the patients with breast cancer.
