ObjectiveTo study the risk factors for children with incomplete Kawasaki disease(IKD) to decrease the development of coronary artery lesions (CAL).MethodsAll children diagnosed as IKD from Jan.2005 to Apr.2011 in our department were reviewed retrospectively for their clinical data,laboratory values and treatment measures.ResultsEight of the children (8/36,22.2% ) were positive for CAL.The count of white blood cell( WBC),count of platelet(PLT),hematocrit and C reactive protein(CRP) level were ( 18.36 ± 4.63) × 109/L,(450.30 ± 155.40) × 109/L,( 25.63 ± 3.53 ),( 18.30 ± 3.80) mg/L and ( 13.48 ±3.27) × 109/L,(350.60 ± 56.80) × 109/L,( 33.78 ± 2.24 ),(9.70 ± 2.50) mg/L in the CAL group and non-CAL group respectively.And there were significant differences on the four indexes between CAL group and non-CAL group ( t =2.58,2.65,2.73,2.48,respectively,P < 0.05 ).Pyretolysis time of children first undergoing globulin treatment was (2.5 ± 1.5 ) d and ( 1.5 ± 1.0 ) d in children under 1-year old and those above l-year old respectively,and the difference was significant ( t =2.35,P < 0.05).ConclusionCAL should be cautiously prevented in IKD infants under l-year old with a fever lasting for over 5 days,decreased hematocrit and elevated WBC count,PLT count,Hct and CRP.Infant IKD patients are not so sensitive to intravenous gamma globulin and tend to occur CAL.They should be given an early diagnosis and timely treatment.

AIM:To investigate the effects of celecoxib on viability , apoptosis and autophagy in acute myeloid leukemia (AML) cell lines HL-60 and HL-60A.METHODS:The HL-60 cells and HL-60A cells were cultured with vari-ous concentrations (0, 20, 40, 60, 80 and 100μmol/L) of celecoxib.The inhibitory effect of celecoxib on the cell viabil-ity was evaluated by MTT assay .Apoptosis was analyzed by Annexin-V/PI staining.Apoptosis-related and autophagy-relat-ed proteins were determined by Western blot .RESULTS:IC50 of celecoxib were 49.4 μmol/L, 32.0 μmol/L and 25.1μmol/L for HL-60 cells treated with celecoxib for 24 h, 48 h and 72 h, respectively.For HL-60A cells, the corresponding IC50 were 69.1 μmol/L, 42.5 μmol/L and 29.6 μmol/L, respectively.The results of flow cytometry analysis showed the proportions of Annexin-Ⅴ+PI-, Annexin-Ⅴ+PI+and Annexin-Ⅴ-PI+cells were increased in the HL-60 cells, and those of Annexin-Ⅴ+PI-and Annexin-Ⅴ+PI+cells were increased in the HL-60A cells treated with celecoxib for 24 h. After treated with celecoxib , the induction of apoptosis was observed , the apoptosis-related proteins cleaved caspase-3 and cleaved PARP were upregulated , the autophagy-related proteins LC3 II and P62 were both increased , and mTOR, p-mTOR, 4-EBP and p-4-EBP were not changed , indicating that celecoxib inhibited autophagy in the AML cells without the mTOR pathway involvement .CONCLUSION:Celecoxib inhibits the viability of HL-60 cells and HL-60A cells in a time-and dose-dependent manner by its effects of inducing apoptosis and necrosis .Celecoxib inhibits mTOR-independent autoph-agy in AML cells, indicating a possible way of using celecoxib for enhancing the antitumor activity of therapeutic agents to induce cytoprotective autophagy in the AML cells .

Objective To explore the application of nerve ultrasound score (DCEC score) in the diagnosis of diabetic peripheral neuropathy. Methods Seventy-three patients with type 2 diabetes were divided into subclinical diabetic peripheral neuropathy group (n=16) and diabetic peripheral neuropathy group (n=58). DCEC score was obtained from all participants. The cut-off value of DCEC score was defined by the receiver operating characteristic (ROC) curve, and its sensitivity, specificity, accuracy, positive likelihood ratio and negative likelihood ratio were analyzed. Results When the DCEC score was ≥14.5, 50 cases of diabetic peripheral neuropathy were diagnosed. The sensitivity was 81.0% , the specificity was 80.0% , the accuracy was 80.8% , the positive likelihood ratio was 4.05, and the negative likelihood ratio was 0.24. Conclusion DCEC score can effectively diagnose diabetic peripheral neuropathy which can be used as a new method to diagnose diabetic peripheral neuropathy.

The incidence and mortality of hepatocellular carcinoma (HCC) in China are among the highest in the world, imposing a heavy social burden. Liver resection and liver transplantation are the primary radical treatments for HCC, although most patients are no longer able to meet the surgical requirements at initial diagnosis. Yttrium-90 microsphere selective internal radiation therapy (90Y-SIRT) has the advantages of shrinking tumors, enlarging residual liver, regressing portal vein tumor thrombus and improving the quality of life, which can be used for conversion, downstaging and bridging therapy for HCC before surgical treatment, enabling patients regain the chance of radical treatment and reducing the postoperative recurrence rate. This review focuses on the clinical application and progress of 90Y-SIRT in this field.
