Objective To investigate the correlated factors of prognosis for acute myeloid leukemia (AML).Methods A retrospective analysis of initial 182 patients with AML was performed to assess the relationship between prognostic factors including sex,age,white cell count at diagnosis,immunophenotype,cytogenetics,allo-HSCT and complete remission (CR) after one-course of induction and overall survival (OS) or event free survival (EFS).Results The median age of 182 patients was 49 (14-80) years old,and the median follow up was 9.7 (0.5-75.5) months.There were 107 patients achieved CR after one-course of induction (total response rate was 65.9 ％,120/182),age≥60 years.CD64 negative,unfavorable cyto-genetics and failing to achieve CR after one-course of induction were associated with lower total CR rate.Univariate analysis results demonstrated that age ≥60 years,unfavorable cytogenetics,CD11b expression and failing to achieve CR after one-course of induction had poor influence on 3-years OS and EFS,while the 3-years OS and EFS for patients with CD19 expression,CD64 expression and allo-HSCT were better than that of the patients with negative CD19 and CD64.Multivariate analysis suggested that age,cytogenetics,CD11b,CD64,allo-HSCT and CR after one-course of induction were independent prognostic factors for OS,while cytogenetics,CD64,allo-HSCT and CR after one-course of induction were important on EFS.Conclusions Prognostic analysis depending on AML corelation factors is benifit to individual therapy and can be applied to improve the survival.

Objective To compare the hemodynamic response to orotracheal intubation by Macintosh laryngoscopy (MAC) with Shikani optical stylet (SOS). Methods Forty neurosurgical patients, ASA physical status Ⅰ~Ⅲ, were prospectively randomized to MAC group (n = 20) and SOS group (n = 20) according to the method of orotracheal intubation. Heart rate (HR) and invasive systolic blood pressure (SBP) were recorded at pre- and post-intubation. Results The intubation time was significantly longer in SOS group than in MAC group [(22 ± 8) s vs. (17 ± 8) s, P < 0.05]. SBP in both groups decreased significantly after induction (P < 0.05) and increased greatly at 1 and 2 min post-intubation (P < 0.05), but did not differ at 3, 4 and 5 min. HR in both groups did not differ significantly between the SBP after induction. HR in both groups increased greatly at 1 and 2 min post-intubation (P < 0.05), but did not differ markedly at 3, 4 and 5 min after induction. There were no significant differences in the peak SBP and HR between the two groups. Conclusion MAC and SOS cause similar hemodynamic responses to orotracheal intubation.

CD5, CD3, CD4 and CD8 cells were measured by flow cytometric analysis. IgG and IgM in the supernatant were detected by ELISA. At the mean time, IgG and IgM in the supernatant of cultured EBV-transformed B lymphocytes were detected by ELISA,and compared with that of UV-inactivated EBV group at the same period.Results:In UV-inactivated EBV group,CD3, CD4 and CD8 T cells couldn’t be detected,CD5 + cells occupied about 42% of all detected cells at the 14th day; and at the 28th day, 47%.The IgG A value of the 10th、18th、22th and 26th day in UV-inactivated EBV group have a significant difference compared with that in the control group ( P

The current official quality control approaches meet the challenges from the complexity of herbal medicines.In fact,any herbal medicines containing numerous unknown components,its curative effect usually depends on the whole of herbal medicines,so it is impossible and unnecessary to qualitatively and quantitatively study every component.By investigating the limitations of current quality control approaches for herbal medicines and the difference and similarity in the chemical substantial style as well as quality control pattern of herbal medicines,a new quality control approach for Chinese herbal medicines should be explored and designed.The combination approach of chemical analysis with bioassay is promising to be developed and employed in order to ensure the safety and efficacy of Chinese herbal medicines.

AIM:To explore the surgical effect of total hip joint replacement on the severe degenerative arthritis secondary to congenital hip dysplasia.METHODS:The experiment was carried out in the Department of pedics,General Hospital of Chinese PLA between June 1998 and December 2005.①116 adult patients(128 hips) with arthritis secondary to dysplastic hip received total hip replacement,including 13 males(15 hips) and 113 females(106 hips),aged from 16 to 66 years(average of 42.6 years).According to Crowe classification system,there were 57 cases(60 hips) of typeⅠ,20(23 hips) of typeⅡ,16(20 hips) of type Ⅲ and 23(25 hips) of type Ⅳ.②The acetabula were reconstructed at the true acetabular location.Except one case,all patients were given biological fixation of cementless acetabular cups including 83 hips with routine total hip replacement,and 27 hips with smaller cup;11 hips with routine total hip replacement after granular bone grafting,and 7 hips with a smaller cup after autologous femoral grafting on the superior margin of acetabula.119 biological prostheses were used to reconstruct the femoral cups including 4 common cemented shafts,6 long cemented shafts,and 4 S-ROM prostheses.③Harris hip score was adopted to evaluate the hip function,and X-ray photographs were used to observe the location of prostheses.RESULTS:①The Harris hip scores increased from 38.5 preoperatively to 88.5 postoperatively.②No prosthesis displacement,dislocation of hip joint or repair was found in patients,and the length of treated limbs meanly prolonged by 2.3 cm.Additionally,the incision healed primarily.③Radiographically,the positions of the prostheses were normal,and the bone grafts fused with the host bone successfully.The average bone coverage was 95%(90%-100%);radiolucentline was observed at between the acetabular cup and host acetabula in 2 cases,and 1 at femur.④Adverse effects:Sciatic nerve tension injury was found in 1 case and recovered in 4 months,the femoral nerve tension injury in 1 case and recovered in 3 months,and hip rest pain remained in 4 cases.CONCLUSION:In the treatment of arthritis secondary to dysplastic hip with total hip replacement,it is better to reconstruct the acetabulum at the true acetabular location.Moreover,the individualized appropriate selection of femoral prostheses is a key factor to obtain good curative effects.

Objective To discuss effects of Wugong Baidu Drink on expressions of Bcl-2, NF-κB mRNA genes related to the apoptosis of HaCaT in psoriasis. Methods Wistar rats were randomly divided into 6 groups:blank group, Western medicine control group, TCM control group, and Wugong Baidu Drink high, medium, and low dose groups. They were given normal saline, methotrexate suspension, compound natural indigo capsule suspension, and the different doses of Wugong Baidu Drink for gavage, respectively. Drug-containing serum of each group was prepared, and was put in the HaCaT respectively to subculture. The intervention effect of different Drug-containing serums on expressions of objective genes were detected through PR-PCR method. Results Drug-containing serum of each group could decrease the expressions of Bcl-2 mRNA and NF-κB mRNA. The most obvious effects were shown in the groups of Western medicine control group and Wugong Baidu Drink high dose group. All Wugong Baidu Drink groups showed a dose-response relationship. Conclusion Wugong Baidu Drink probably can promote the apoptosis of HaCaT by reducing the gene expressions of Bcl-2 and NF-κB. It can also decrease immune response by regulating serum factors related to T cells to play the role of anti-psoriasis.
