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.

Objective To investigate the effect and side effects of flurbiprofen axetil combined with fentanyl in postoperative patient-controlled analgesia (PCA) after craniotomy.Methods 60 patients undergoing scheduled craniotomy were randomly divided into the treatment group and control group with 30 cases in each group, and received flurbiprofen axetil combined with fentanyl and only fentanyl respectively in PCA after craniotomy. The visual analogue scale (VAS), sedation score (SS) and the side effects were evaluated in 24 h after craniotomy.Results There was no significant difference in VAS between the two groups ( P>0.05). The SS, side effects such as nausea and vomiting in the treatment group were significantly less than that in the control group ( P<0.05).Conclusion Flurbiprofen axetil combined with fentanyl in PCA can reduce the side effects of fentanyl and offers overall favorable analgesic responses.

OBJECTIVETo investigate the current situation of treatment for acute chemical poisoning in the emergency departments and occupational disease departments of some general hospitals and to provide a basis for improving the ability of general hospital to deal with acute chemical poisoning.

METHODSFour hospitals from Shandong Province, Beijing City, and Shanxi Province, China were selected in the study. They included two first-class hospitals located in the downtown, where the patients with acute chemical poisoning from urban and suburban areas were admitted to the occupational disease departments, and two second-class hospitals located in the suburban area or county, where the patients with acute chemical poisoning from the suburban area were admitted to the emergency departments. A questionnaire survey was conducted in 141 medical workers (51 persons in the emergence department group and 90 persons in the occupational disease department group) that were engaged in the treatment of acute chemical poisoning in the four hospitals; 1999 medical records were analyzed. Individual in-depth interviews, questionnaire investigation, and field observation were used to compare the emergency department group and occupational disease department group in terms of the ability to deal with acute chemical poisoning and the training on treatment for acute chemical poisoning.

RESULTSThe emergency department group had significantly higher proportion of pesticide poisoning cases than the occupational disease department group (P<0.01). Thirty-seven of the patients in occupational disease department group died, with a fatality rate of 2.7%, and 14 of the patients in emergence department group died,with a fatality rate of 2.2%, so there was no significant difference between the two groups in this regard (P>0.05). There were significantly more cases treated without emergency plan in the emergency department group than in the occupational disease department group ( 37.3% vs. 10.0%, P <0.0 1). The occupational disease department group had significantly higher score of knowledge about the treatment for acute chemical poisoning than the emergence department group (7.2±1.3 vs. 5.2±0.9, P<0.01 ). There were significantly lower proportions of medical staff who had received training on the knowledge about acute chemical poisoning and on the emergency disposal of acute chemical poisoning in the emergency department group than in the occupational disease department group (P<0.05).

CONCLUSIONThere is a lack of the knowledge about treatment for acute chemical poisoning and protective measures during treatment among the medical staff in general hospitals, and related training and emergency plan are needed.

A quantitative analysis method of multi-components with a single marker (QAMS) for simultaneous determination of six marker compounds (one from phenolic acids and five from phthalides) in Chuanxiong Rhizoma was established by applying HPLC and using butylidenephthalide as the internal reference substance. And also the feasibility and accuracy of the established method for quality evaluation and application of Chuanxiong Rhizoma were investigated and validated. The analysis was performed with the mobile phase consisting of acetonitrile - 0.2% aqueous formic acid. The flow rate was 1.0 mL . min-1 and the column temperature was maintained at 30 °C. The detection wavelengths were set at 252 nm (for ferulic acid, Z-ligustilide, and butylidenephthalide) and 266 nm (for senkyunolide I, senkyunolide A, and coniferyl ferulate), separately, and 20 µL was injected for analysis with gradient elution. The results showed that there were no significant differences observed between the HPLC-QAMS method and the external standard method (RSD <5%). The relative correction factors were credible (RSD < 5%) in changed chromatographic conditions. The established HPLC-QAMS method can be accurately used for simultaneously evaluating and controlling the quality of Chuanxiong Rhizoma with multi-components.
