Objective To detect the expression of SALL4 in patients with acute myeloid leukemia (AML) and analyze its potential clinical significance. Methods Reverse transcription polymerase chain reaction and Real-time fluorescence quantitative reverse transcription polymerase chain reaction (FQ-RT-PCR) was used to examine SALLA expression in peripheral blood mononuclear cells (PBMCs) of 68 cases of AML including 36 cases in acute phase and 32 cases in remission phase, 30 healthy controls, Kasumi-1 cells and THP-1 cells. Then, flow cytometry, bone marrow smear and automated hematology analyzer were used to analyze the relationship between the SALL4 expression and blast cell counts in the bone marrow, peripheral white blood cell (WBC) counts, peripheral large unstained cell (LUC), CD34 in blast cells. Further, the change of SALL4 level during pre-chemotherapy, chemotherapy (2nd w to 3rd w) and remission were investigated in 5 AML cases. Results The level of SALL4 expression in patients with AML in acute phase [69.01 (17.20-120.28)] was 26-fold and 61-fold high compared with that in remission phase [2.64(1.35-5.41)] and in healthy control [1.14(0.50-1.62)] (Z=-6.48,-6.83,P<0.01). The level of SALL4 expression in remission phase was 2.3-fold high compared with that in healthy control (Z=-3.61 ,P<0.01). The expression level of SALL4 was decreased along with efficient chemotherapy in 5 AML cases in which SALL4 expression level was 79.74 (33.76-89.09), 7.19 (5.97-20.21) and 3.40 (1.44-15.53) during pre-chemotherapy, chemotherapy (2nd w to 3rd w) and remission, respectively. In groups of abnormal increased counts of blast cell, peripheral LUC% and CD34%, expression of SALL4 [33.82 (16.00-144.01), 30.70(23.75-72.50) and 56.25(23.79-153.81), respectively] were higher than that in groups of normal counts [2.74 (1.59-5.13), 5.71 (2.52-22.40) and 20.82 (14.03-55.12), respectively ] (Z=-4.64,-2.18,-3.66,P<0.01 or P<0.05). The expression of SALL4 in the group of increased WBC counts [89.26(23.75-154.34)] was higher than that in the group of normal WBC counts [3.86(2.03-6.01)] and the group of decreased WBC counts [6.66(2.51-17.06)] (Z=-4.91,-4.21,P<0.01). The level of SALL4 expression was positively correlated with blast cell counts in bone marrow and peripheral WBC counts (r=0.45,0.40,P<0.01). Conclusions FQ-RT-PCR method can be used successfully to detect the expression of SALL4,and the expression of SALLA may be useful to predict disease progression of AML.

Objective To explore the outcomes of kidney transplant recipients who developed urinary and male genital cancers after transplantation. Methods Data of 31 kidney transplant recipients developed de novo urinary and male genital cancer were compared with data of 31 patients in general population with the same age and same tumor stage. Results Compared with the general population, the overall survival was significantly worse in the transplant recipients (P=0. 02) , 5-year survival rates for each group were 50% vs 68%. Multivariate analyses demonstrated cancer stage to be a negative risk factor for survival for transplant recipients with de novo urinary and male genital cancer, and surgery and functioning graft to be the positive survival predictors. Conclusions Transplant recipients experience worse outcomes than the general population from urinary and male genital cancers. Cancers in transplant recipients are more biologically aggressive at the time of diagnosis.

Objective To observe the effect of hemoperfusion on micro-inflammation in patients with maintenance hemodialysis (MHD).Methods Fifty MHD patients (MHD group) and 25 healthy volunteers (control group) were involved in this study.The MHD patients were divided into two groups by random digits table:hemoperfusion combined with hemodialysis group (HP + HD group,25 cases) and hemodialyais group (HD group,25 cases).The plasma levels of micro-inflammatory cytokines including high-sensitive C-reactive protein (hs-CRP),interleukin-6 (IL-6) and tumor necrosis faetor-α (TNF-α ) were measured before and after treatment.Results The plasma levels of hs-CRP,IL-6 and TNF-α in MHD group were significantly higher than those in control group [(6.72 ± 2.63) mg/L vs.(1.35 ± 0.92) mg/L,(348.83 ± 64.41) ng/L vs.(54.49 ±22.47) ng/L,(7.52 ± 3.17) ng/L vs.(2.53 ±0.88) ng/L](P＜0.05).There was no significant difference in the plasma levels of hs-CRP,IL-6,TNF-α before treatment between HD group and HP+HD group (P＞0.05),Compared with those in HD group,the plasma levels of hs-CRP,IL-6 and TNF-α after treatment in HP+HD group were significantly decreased [(4.78 ±2.49) mg/L vs.(6.89 ±2.69) mg/L,(260.54 ±56.72) ng/L vs.(357.14 ±56.37) ng/L,(5.36 ±2.41) ng/L vs.(7.49 ±2.87) ng/L] (P <0.05).Conclusion Hemoperfusion improves micro-inflammation in patients with MHD.

Objective To describe the CT manifestations of thymic epithelial tumor and explore the correlation between CT findings and post-operative tumor-related survival time. Methods Ninety-one patients who underwent CT scan before operation were reviewed retrospectively. All cases had operation and were classified according to the WHO classification. The size, contour, shape, density and enhancement of the tumors on CT were assessed. Presence of mediastinal lymphadenopathy, great vessel invasion, metastasis to the lung or plural, myasthenia gravis (MG) were also analyzed. The survival rate was obtained using the Kaplan-Meier method. The Cox model was applied to determine the factors affecting the tumor-related survivals. Chi square test was used to analyze the relationship between CT findings and WHO classification. Results Two patients were excluded because of dying of myocardial infarction and colon cancer. The total 5-year survival rate was 84.3%(n=75). Eighty-nine patients had total 91 tumors. Tumors with diameter larger than 5 cm, lobular contour, heterogenous density, and presence of great vessel invasion, mediastinal lymphadenopathy, and metastasis were adverse factors which could significantly affect the survival time. Five-year survival rates of these factors were 72.7%, 77.3%, 76.7%, 73.8%, 30.0%, and 68.8%, respectively. Presence of MG was a favorable factor which also significantly affected the survival time (P＜0.05). While the shape and enhancement of the tumors and the age, gender of the patients did not significantly affect the survival time (P＞0.05). The result of the Cox multivariate analysis was consistent with that of the Log-rank test. For different WHO classification, there were significant different among the size or contour of the tumors, presence of great vessel invasion, mediastinal lymphadenopathy, and metastasis (x2 value were 6.598, 5.737, 18.307, 8.465, and 15.608, respectively P＜0.05). Conclusions CT findings may be served as predictors of clinical prognosis of the thymic epithelial tumors. Adverse factors for survival time are the size of the tumors and presence of mediastinal lymphadenopathy, while MG is a favorable factor for survival time.

Objective To investigate the effect of the bedside lung ultrasound in emergency (BLUE)-plus lung ultrasound protocol on lung consolidation and atelectasis of critical patients.Methods All patients who need to receive mechanical ventilation for more than 48 hours in ICU from June 2010 to December 2011 in Peking Union Medical College Hospital were included in the study.BLUE-plus and BLUE lung ultrasound,bedside X-ray,lung CT examination were performed on all patients at the same time.The condition of lung consolidation and atelectasis discovered by BLUE-plus lung ultrasound protocol was recorded and compared with bedside X-ray or lung CT.The difference in assessment of lung consolidation and atelectasis between BLUE-plus lung ultrasound protocol and BLUE protocol was compared.Results A total of 78 patients were finally enrolled in the study.The lung CT found 70 cases (89.74％) had different degrees of lung consolidation and atelectasis.The sensitivity,specificity and diagnostic accuracy of lung consolidation and atelectasis by the bedside chest X-ray were 31.29％,75.00％ and 38.46％,respectively.BLUE-plus lung ultrasound protocol found 68 cases with lung consolidation and atelectasis,and its sensitivity,specificity,and diagnostic accuracy were 95.71％,87.50％ and 94.87％,respectively,which were significantly higher than those of lung CT.BLUE protocol found 48 cases of lung consolidation and atelectasis,and its sensitivity,specificity,and diagnostic accuracy were 65.71％,75.00％ and 66.67％,respectively.The position of lung consolidation and atelectasis which hadn't been found by BLUE protocol was mainly proved to be located in the basement of lung by lung CT.Conclusions The incidence of lung consolidation and atelectasis in critical patients who received mechanical ventilation is high.The BLUE-plus lung ultrasound protocol has a relatively higher sensitivity,specificity and diagnostic accuracy for consolidation and atelectasis,which can find majority of consolidation and atelectasis.As BLUE-plus lung ultrasound is a bedside noninvasive method allowing immediate assessment of most lung consolidation and atelectasis,it will be likely the alternative of the CT and play a key role in assessment of lung consolidation and atelectasis.

OBJECTIVETo study clinical effects of short-segment fixation and injured vertebra bone grafting through injured pedicle for the treatment of thoracolumbar burst fractures under MAST Quadrant retractor via a paraspinal muscle approach.

METHODSThe data of 42 patients with thoracolumbar burst fractures treated from June 2009 to September 2012 were reviewed. There were 19 males and 23 females, with an average age of (55.2±11.9) years old. The mean injury time was (5.8±4.3) days. Fracture segments included T10 in 3 cases, T11 in 6 cases, T12 in 13 cases, L1 in 9 cases, L2 in 7 cases, and L3 in 4 cases. According to Denis classification, 9 patients were type A, 21 patients were type B, 5 patiens were type C, 5 patients were type D, and 2 patients were type E. All the patients were treated with short-segment pedicle screw-rod system fixation under MAST Quadrant via the paraspinal muscle approach. The operative time, blood loss, complications and the height of vertebra, kyphosis Cobb angle, VAS scores, JOA scores were measured before and after treatment.

RESULTSAfter treatment, the vertebral height and kyphosis Cobb angle were restored. Compared with preoperative results, postoperative vertebral height and kyphosis Cobb angle, VAS scores and JOA scores were all improved. But there was no statistically significance in vertebral height, kyphosis Cobb angle between postoperative at 1 week and 1 year.

CONCLUSIONInternal fixation combined with injured vertebra bone grafting through the injured pedicle for the treatment of thoracolumbar burst fractures via the paraspinal intermuscular approach under MAST Quadrant is a safe, minimally invasive, effective and satisfactory method.
