Objective To investigate the role of gamma-aminobutyric acid transporter-1 (GAT-1) in the spinal cord in a rat model of bone cancer pain.Methods Eighty female SD rats weighing 150-180 g were randomly divided into 5 groups (n =16 each): sham operation group(group Ⅰ ),bone cancer pain group(group Ⅲ ),sham operation+ NO-711 group(group Ⅲ ),Ⅳ group BCP + NO-711 group(group Ⅳ ) and BCP + vehicle group (group Ⅴ ).Bone cancer pain was induced by inoculating Walker-256 mammary gland carcinoma cells into medullary cavity of tibia.NO-711 (20 μg,10 μl) was administered intrathecally once a day for 3 consecutive days from the 14th day after operation.Mechanical withdrawl threshold (MWT) of mechanical stimulus was determined the day before operation and at days 3,5,7,10,14 and 16 after operation.The animals were sacrificed on the 16th day after operation,and then the spinal cords were removed for determination of the expression of GAT-1 and double immunostaining of GAT-1 and glial fibrillary acidic protein (GFAP,astrocyte marker).Results MWT were significantly decreased in groups Ⅱ,Ⅳ and Ⅴ as compared with groups.Ⅰ and Ⅲ.The expression of GAT-1 significantly up-regulated in groups Ⅱ,Ⅴ as compared with groups Ⅰ and Ⅲ.NO-711 significantly increased MWT,while decreased the expression of GAT-1 in group Ⅳ compared with groups Ⅱ and Ⅴ.The expression of GAT-1 up-regulation appeared colocalizes with in astrocytes activation in spinal dorsal horn.Conclusion The up-regulation of expression of GAT-1 in spinal cord is involued in the development and maintenance of bone cancer pain,which may be related to the astrocytes activation.

Objective To describe the sonographic features of abdominal wall endometriosis(AWE).Methods 105 consecutive women with proven pathological endometriosis of the abdominal wall were retrospectively recruited.The clinical data and the result of the sonographic examinations were reviewed and described.The AWE lesions were divided into ＜3 cm and ≥3 cm groups according to their maximum diameter.Results The sonographic feature of AWE includes irregular hypoechoic nodules with ill-defined margins,anechoic and hyperechoic ring maybe exist.In color Doppler,most of them showed few internal vascularity.Compared with≥3 cm group,＜3 cm group nodules manifested as shorter latent period,with more superficial location,round or oval shape,peripheral hyperechoic ring and none or few vascularity were more common.As for ≥3 cm group nodules manifested as longer latent period,with deeper location,irregular shape,abundant of vascularity were more common.Conclusions Specific diagnosis of AWE can be made by using high frequency sonography combined with clinical features.More accurate information can be provided by judging the size,range and infiltrative depth.

Objective:To explore the implicit attitude and explicit attitude toward death of college students,and the relationship between the two kinds of attitude.Methods:Totally 65 college studems participated in this study.The Single Category Implicit Association Test (SC-IAT,including cognition,affection and behavior) was used to exam the implicit attitude toward death of undergraduate students.The Death Attitude Profile-Revised (DAP-R,including five dimensions,i.e.,fear of death,death avoidance,death acceptance,escape acceptance,and neutral acceptance) was used to measure the explicit attitude.Results:Data of the SC-IAT indicated that the differences between the mean reaction time of the incompatible task and compatible in all three dimensions and the total SC-IAT were significant (Ps ＜0.01),and both the D scores of the total SC-IAT and three dimensions were larger than zero.The mean score of neutral acceptance was the highest in the five factors of SC-IAT.Relationships between the implicit effect of SC-IAT and the Mean scores of the DAP-R's five factors were not significant(Ps ＞ 0.05).Conclusion:The implicit attitude toward death of college students is negative,the explicit attitude toward death of college students is neutral.The implicit and explicit attitude toward death of college students is incongruent,and they are relatively independent.

OBJECTIVE:To compare the clinical efficacy and safety of imipenem and cislastatin sodium and meropenem in the treatment of acute leukemia granulocytopenic phase combined with severe lung infection. METHODS:A total of 64 patients with acute leukemia granulocytopenic phase combined with severe lung infection were selected from our hospital during Jul. 2015-Jul. 2016 as study objects. They were divided into trial group(odd number)and control group(even number)according to admis-sion order,with 32 cases in each group. Control group was given Meropenem for injection 1 g+0.9％ Sodium chloride injection 100 mL,ivgtt(about 30 min),q8 h. Trial group was given Imipenem and cislastatin sodium for injection 1 g+0.9％ Sodium chlo-ride injection 100 mL,ivgtt(about 30 min),q12 h. Both groups were treated for 14 d. Clinical efficacies as well as blood gas pa-rameters [p(O2),p(CO2),SaO2] and pathogenic clearance were observed in 2 groups,and the occurrence of ADR was recorded. RESULTS:The total response rate of trial group(78.13％)was significantly higher than that of control group(71.88％),with sta-tistical significance (P<0.05). Before treatment,there was no statistical significance in blood gas parameters or the number of detected pathogenic strains between 2 groups (P>0.05). After treatment,the levels of p(O2) and SaO2 in 2 groups were in-creased significantly,while the level of p(CO2) was decreased significantly;there was statistical significance compared to be-fore treatment(P>0.05). There were 27 cases of pathogenic clearance in trial group(clearance rate of 84.38％),which was sig-nificantly more than control group (26 cases,clearance rate of 81.25％),without statistical significance (P>0.05). The inci-dence of ADR in trial group(9.38％)was significantly lower than control group(15.63％),without statistical significance(P>0.05). CONCLUSIONS:Imipenem and cislastatin sodium and meropenem show good clinical efficacy for acute leukemia granu-locytopenic phase combined with severe lung infection,blood gas parameters improvement and pathogenic clearance effect,both of them have good safety.

Objective:To investigate the expression and prognostic significance of CD19 in patients with Acute myelogenous leukemia with AML1-ETO positive. Methods: Clinical data of 66 patients AML with AML1-ETO positive who were newly diagnosed from Jan 2010 to Dec 2015 were collected. To retrospectively analyze the relationship between clinical characteristics and expression of CD19,so dose the prognosis. Results:The positive rate of CD19 expressing in AML with AML1-ETO positive was 50. 0%. There were no statistically significant differences in terms of age,gender,hemoglobin,platelet,percentage of bone marrow blasts,accompanied with chromosome ,gene mutations between patients with and without CD19 expression(P>0. 05). The white blood cell count(WBC) of the CD19 negative group was higher than CD19 positive group,while showed significant difference(P=0. 027). Although the relapse-free survival (RFS) of patients with CD19 expression was higher than those without,no significant difference was calculated (P=0. 105). Patients with CD19 expression had superior overall survival ( OS ) compared to those without CD19 expression ( P = 0. 030 ) . Multivariable analysis for OS identified CD19 positivity as an independent predictor associated with better prognosis. Conclusion: The expression of CD19 in AML with AML1-ETO positive may be an indicator associated with better prognosis.
