Lenalidomide is an oral immunomodulator with multiple functions including immune regulation, anti-tumor, and regulation of tumor microenvironment. Since the United States Food and Drug Administration (FDA) approved lenalidomide for the treatment of mantle cell lymphoma, recent studies have indicated that lenalidomide monotherapy or lenalidomide combinations in other types of lymphoma also has broad prospects. The treatment progress of lenalidomide in lymphoma will be summarized in this paper based on the new reports in the 57th American Society of Hematology (ASH) annual meeting.

PET-CT is the only current medical imaging technology to provide both metabolic and morphologic information in anatomical configuration mode,with high sensitivity and non-invasion.As one of the optimal measures in tumor diagnosis and therapy,abnormally-increased FDG uptake of some subtypes therefore makes an increasing application of PET-CT in lymphoma.The progress of PET-CT in lymphoma will be summarized in this paper based on the reports from the 58th American Society of Hematology Annual Meeting.

To explore the regulation of eIF4E, we screened the protein interacting with eIF4E from human cDNA library by using yeast two-hybrid system. Several clones interacting with eIF4E were identified. One of them was homologous with HUWE1 (HECT, UBA and WWE domain containing 1, also named as ARF-BP1, HECTH9 or HUWE1). Cell co-immunoprecipitation showed that eIF4E could bind to HUWE1 in mammalian cells. We also found that HUWE1 bearing the HECT domain is necessary for its association with eIF4E.

BACKGROUND:Previous studies have shown that continuous administration of 1×107 of bone marrow mesenchymal stem cel s can induce immune tolerance in rats undergoing kidney transplantation, but it is not yet found clinical y that curcumin exerts an on immunomodulatory effect on kidney transplantation.
OBJECTIVE:To investigate the effects of different concentrations of curcumin on bone marrow mesenchymal stem cel s-induced immune tolerance in rats after kidney transplantation.
METHODS:Rat model of kidney transplantation was made, and rat models were randomly divided into four groups:transplantation group with no treatment;bone marrow mesenchymal stem cel s group (cel group) injected with 1×107/kg bone marrow mesenchymal stem cel s via the left iliac vein (before peritoneal suture) and tail vein (from the 2nd day) for 10 days;bone marrow mesenchymal stem cel s+low/high dosage of curcumin groups (low/high dosage curcumin groups) injected intragastrical y with 2 or 10 mg/kg curcumin combined with injection of bone marrow mesenchymal stem cel s for 10 days. Transforming growth factor-β1 protein expression in the kidney tissues was examined by immunohistochemical staining. The concentrations of interleukin-2 and interleukin-6 in serum were detected by ELISA assay.
RESULTS AND CONCLUSION:After kidney transplantation, the protein expression of transforming growth factor-β1 in renal tubular epithelial cel s and renal interstitial cel s as wel as the concentrations of interleukin-2and interleukin-6 in serum were significantly higher in the transplantation group than the other groups (P<0.05). Compared with the cel transplantation group, the protein expression of transforming growth factor-β1 as wel as the concentrations of interleukin-2 and interleukin-6 reduced significantly in the low/high dosage curcumin groups (P<0.05). These findings indicate that simultaneous administration of curcumin and bone marrow mesenchymal stem cel s can effectively inhibit immune rejection reaction and improve renal function in rats after kidney transplantation.

AIM: To compare the clinical results of suture method and partial eyelash resection treating for pediatric eyelid trichiasis, and screen an effective method for the treatment of pediatric lower eyelid trichiasis.
METHODS: Fifty-six cases of pediatric patients with lower eyelid trichiasis were randomly divided into a control group and an observation group in accordance with the method of drawing lots, and each group was 28 cases. The control group was treated with suture method, and the observation group was treated with partial eyelash resection. The clinical efficacy, patient satisfaction before and after treatment, and the incidence of complications were compared.
RESULTS:(1) The clinically total effective rate was 74%of the control group, which was 89% of the observation group, and there were statistical differences of the clinical efficacy between the two groups ( P<0. 05 ); ( 2 ) the satisfaction scores were (3. 89±1. 22) points and (6. 27±1-86) points of the the control group before and after treatment, which were ( 4. 00±1. 34 ) points and ( 8-95±2-34) points of the observation group, and there were statistical differences of the two groups before and after treatment (P<0. 05), and the scores of the observation group were higher than that of the control group ( P<0-05);(3) complications such as swelling and stitches off appeared in both groups, and the rate was 21% in the control group, which was 11% in the observation group, and there were statistical differences between the two groups (P<0. 05).
CONCLUSION: The treatment of children with lower eyelid trichiasis, suture method is simple and can be performed under local anesthesia in collaboration with children, but with a higher relapse rate, some patients required reoperation;partial resection of eyelashes can be more thoroughly solve the problem of pediatric eyelid trichiasis with low recurrence rate, but children need to be under general anesthesia with some of big risk. So partial resection of eyelashes is unsuitable for using in clinical practice widely and can be used in special cases.

Objective To quantify the concentration of peripheral blood plasma neutrophil gelatinase-associated lipocalin (NGAL) in patients with acute pancreatitis (AP) and to explore its value in assessment of the severity of AP.Methods From June 2011 to March 2012,83 patients with AP were selected,among those 43 cases were mild acute pancreatitis (MAP) and 40 were severe acute pancreatitis (SAP).The control group included 30 healthy individuals.The peripheral blood of patients with AP and healthy controls was collected,and plasma was isolated after centrifuged.The concentration of NGAL in plasma was detected by enzyme-linked immunosorbent assay (ELISA).The t-test was performed for comparison between groups.The correlation between the concentration of NGAL in plasma and clinical parameters of AP was analyzed by Spearman rank order correlation analysis.The diagnosis value of the concentration of NGAL in SAP was evaluated by receiver operating characteristic (ROC) curve and area under the curve (AUC).Results The concentration of plasma NGAL in AP group ((10.30± 5.97)nmol/L) was higher than that in healthy control group ((1.94±1.35) nmol/L) and the difference was statistically significant (t=11.924,P＜0.01).The concentration of plasma NGAL in SAP group ((14.61 ±5.28) nmol/L) was higher than that in MAP group ((6.27±-3.09) nmol/L) and healthy control group,the differences was statistically significant (t=8.677 and 14.539,both P＜0.01).The concentration of plasma NGAL of AP patients was positively correlated with acute physiology and chronic health evaluation-Ⅱ score,Ranson score,bedside index for severity in acute pancreatitis score,computed tomography (CT) severity index,C-reactive protein,white blood cells and the days of hospitalization (r=0.651,0.556,0.514,0.620,0.320,0.458 and 0.346,all P＜0.05).The area under the ROC curve of plasma NGAL concentration in diagnosis of SAP was 0.926 (95％CI:0,870-0.983).The cutoff value of plasma NGAL level in diagnosis of SAP was 8.44 nmol/L.The sensitivity and specificity was 87.5 ％ and 88.9％,respectively.Conclusions Plasma NGAL level is correlated with the severity of patients with AP.NGAL may be one of the markers for the early diagnosis of SAP.
