Background and Purpose:It has been proved that CD117 may be used as an immunology marker for diagnosis of leukemia of myeloid origin.The relationship between CD117 expression and effect of chemotherapy on the patients with Acute Nonlymphoblastic Leukemia(ANLL) remains unclear.This study is to investigate the relationship between CD117 expression and the response of patients with ANLL to chemotherapy.Methods:Flow cytometery(FCM) was used to detect the positive rate and the levels of CD117 expression of the bone marrow mononuclear cell(BMMNC) from 38 patients with acute lymphoblastic leukemia(ALL) and 81 patients with ANLL,respectively.All-trans Retinoic Acid(ATRA) was taken to treat M_(3) type of ANLL and protocol DA and/or HA was used to treat the other types.ANLL was divided into two groups: positive(+) and negative(-) expression of CD117.At the same time we compared the difference of rates of complete remission(CR) between CD117(+) and CD117(-) groups from ANLL after chemotherapy.Results:Positive percentage of expression of CD117 in ALL and ANLL groups were 13% and 70% respectively(P=0.000).Positive levels of CD117 decreased successively as follows: M_(3)/ M_(1)、M_(2)/ M_(6) / M_(4)、M_(5).CR rates of CD117(+) and CD117(-) groups of ANLL after chemotherapy were 51%(29/57) and 67%(16/24)(P=0.192),respectively.Conclusions:CD117 may serve as an immunology marker for the diagnosis of ANLL,but positive or negative expression of CD117 in ANLL was not associated with the response of the patients with ANLL to chemotherapy.

Objective:To study expressions of CD117 and CD34 in the patients with acute promyelocytic leukemia(APL,M3) and in M1-M2 subtype from FAB classification for acute leukemia(AL).The focus of the study would be laid on the clinical significance of CD117/CD34 co-expression in the patients of M3 subtype.Methods:Researched cases of acute nonlymphoblastic leukemia(ANLL) were divided into two groups:M1-M2 subtype and M3 subtype.Flow cytometery(FCM) was used to detect the rates of positive expression of CD117 and CD34 on bone marrow mononuclear cell(BMMNC) in 54 patients of M3 and 63 patients of M1-M2 subtype respectively.Meanwhile,we compared the differences between the rates of expression of CD117 and CD 34.And,the rates of CD117/CD34 co-expression in patients of M1-M2 subtype and M3 subtype were studied.Results:Our results revealed that the positive rates of CD117 expression in M1-M2 subtype and M3 subtype were 71.4%(45/63) and 66.7%(36/54) respectively(P=0.58).The positive rates of CD34 expression in M1-M2 subtype and M3 subtype were 66.7%(42/63) and 11.1%(6/54) respectively(P=0.000).The positive rates of CD117/CD34 co-expression in M1-M2 subtype and M3 subtype were 71.1%(45/63) and 7.4%(4/54) respectively(P=0.000).Conclusion:CD117 may be used as immunology marker for leukemia of myeloid origin.CD34 had lower expression in M3 subtype than in M1-M2 subtype.The positive rate of CD117/CD34 co-expression in M3 subtype was significantly lower than that in M1-M2 subtype,which can help for diagnosis of M3 subtype and help differentiate M3 subtype from M1-M2 subtype as well.

Purpose It has been demonstrated that hepatocytes uptake of Gd-EOB-DTPA obviously decreased,which would result in decreased liver-to-lesion contrast.Therefore,this study was to evaluate the potential of increasing flip angle to improve the image quality of Gd-EOB-DTPA enhanced MR.Materials and Methods A total of 114 patients with focal liver lesions (FLLs),who underwent Gd-EOB-DTPA-enhanced MR of the liver,were enrolled in this retrospective study.39 patients were noncirrhotic group,36 patients were Child-Pugh A group,23 patients were Child-Pugh B group,and 16 patients were ChildPugh C group.Tl-weighted with fat suppression volume interpolated breath hold examination (VIBE) sequence was acquired before and 5 min,10 min,15 min,20 min after the administration of Gd-EOB-DTPA with both conventional low FA (9 °) and high FA (27 °) protocols separately.Signal to noise ratio (SNR),liver to lesion contrast (LLC),the liver to lesion SI ratio (LLSIR) were calculated and analyzed between low and high FA protocol images in each group and each scan time.Results The LLC and LLSIR on GdEOB-DTPA-enhanced MR images using a high FA (27 °) protocol were significantly higher in comparison with the conventional low FA (9°).In Child B group and Child C group,the LLC and the LLSIR with low FA significantly reduced during 15～20 min after contrast agent injection,however with high FA,the value of LLC and LLSIR tended to be horizontal.Conclusion A high FA protocol in comparison with the conventional 9° FA can obviously improve the image quality,which is reliable for liver lesion depiction on GdEOB-DTPA-enhanced MR images,especially to those with severe liver cirrhosis.

24 cases of renal failure induced by chemotherapy were treated with Wuling powder plus additives.Theresult of clinical amelioration was 87.5%.with a to-tal effective yielded marked actions of promoting ap-petite in animals,lowering serum urea nitrogen,cre-atinine,2 microglobulin.It also decreased the inhibi-tion of PDD on the enzyme activity of renal Na~+—K~+ATP.Microscopic exam revealed the pathological le-sion of kidney to be milder in the tested group.

OBJECTIVETo study the effects of dopamin receptors-2 (DR2) on myocardial ischemic postconditioning and explore its underlying mechanisms.

METHODSThe myocardial ischemic postconditioning (PC) model was established in cultured primary rat neonatal cardiomyocytes which were then randomly assigned in the following groups: Nomial control group, Isehemia/reperfusion (L'R) group, PC (ischemic postconditioning) group, PC + Bro (Bromocriptine, a DB2 antagonist) group, PC + Hal (Haloperidol, a DB2 repressor) and PC + Hal + Bro groups. The lactate dehydrogenase (LDH) and superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in cell medium were analyzed by colorunetry. The cell ultrastructure changes were observed by transmission electron microscope. The cell apoptosis was analyzed using flowcytometiy. The protein expression level of D112 and activity of p-p38 and p-JNK were detected by Western blot.

RESULTSCompared with the nonnal control group, hR increased the protein expression level of DB2, enhanced LDH activity and MDA content, promoted cell injury and apoptosis, decreased SOD activity, up-regulated the activity of p-p38 and p-JNK. Compared with the hR group, although PC further increased the expression of DR2 protein, it decreased LDH activity and MDA content, cell injury and apoptosis, increased SOD activity, down-regulated activity of p-p38 and p-JNK. Bromocriptine treatment further enhanced PC-induced canlioprotective effect, yet Hal addition attenuated this enhancing effect exerted by bromocriptine.

CONCLUSIONThe activation of DB2 is involved in the protective effect of ischemic postconditioning on myocardial ischemia/reperfusion injury through down-regulating the activity of p-p38 and p-JNK.
