Objective:A more effective approach to judge the fissure fracture by using image enhancement is presented.Methods:The Gradient image after 5×5 median filtering smoothing was used to mask the laplace image, and to add the original image in order to informing the sharpening image, and then the adaptive contrast histogram equalization is put in shaping image and to compare the effect of the image enhancement.Results: The algorithm to enhance the X-Ray fracture image can highlight the shape of the fissure fracture clearly. The enhanced image is more effective than the image by using one way alone.Conclusion: This method is valuable in judging the fissure fracture in clinical diagnosis.

Despite many recent advances in the treatment of multiple myeloma (MM), the course of the disease is characterized by a repeating pattern of periods of remission and relapse as patients cycle through the available treatment options. Evidence is mounting that long-term maintenance therapy may help suppressing residual disease after definitive therapy, prolonging remission and delaying relapse. For patients undergoing autologous stem cell transplantation (ASCT), lenalidomide maintenance therapy has been shown to improve progression-free survival (PFS), however, it is still unclear whether this translates into extended overall survival (OS). For patients ineligible for ASCT, continuous therapy with lenalidomide and low-dose dexamethasone is shown to improve PFS and OS (interim analysis) compared with a standard, fixed-duration regimen of melphalan, prednisone, and thalidomide in a large phase Ⅲ trial. Other trials have also investigated thalidomide and bortezomib maintenance for ASCT patients, and both agents have been evaluated as continuous therapy for those who are ASCT ineligible. However, some important questions regarding the optimal regimen and duration of therapy must be answered by prospective clinical trials before maintenance therapy, and continuous therapy should be considered routine practice. This article reviewed the available data on the use of maintenance or continuous therapy strategies and highlights ongoing trials reported in the 57th American Society of Hematology (ASH) annual meeting that would help to further define the role of these strategies in the management of patients with newly diagnosed MM.

In this last decade,one of the major advances in the management of multiple myeloma has been the introduction of the novel agents thalidomide,bortezomib,and lenalidomide as part of treatment in young patients eligible for high-dose therapy (HDT) and autologous stem cell transplantation (ASCT).These drugs have markedly improved the rate of complete remission both before and after ASCT without substantially increasingly toxicity.The implementation of an ‘optimal strategy’ consisting of novel-agent-based induction,HDT,and the use of novel agents in consolidation and maintenance may result in 5-year survival rate of 80 ％ and cure might be considered in a subset of patients who present with good prognostic features at the time of diagnosis.Nevertheless,the high efficacy of the novel agents has led some groups to test these agents upfront without ASCT.At the end of 2014,preliminary randomized data favor early ASCT plus novel agents over novel agents alone.Therefore,the optimal approach to the treatment of multiple myeloma is still to propose the most effective treatment that should involve the use of frontline ASCT in young patients eligible for HDT.This article reviews the latest research presented at the 56th American Society of Hematology (ASH) annual meeting on the multiple myeloma and its clinical management.

Multiple myeloma (MM) is a plasma cell malignancy. With the development of the understanding of MM, the diagnosis is no more limited to bone marrow biopsy and imageological examination. Serum free light chain, cytogenetic analysis and molecular biology study are becoming increasingly widely used, which give us a deeper under-standing of the mechanisms of MM and provide us with a clearer prognosis evaluation. Here is to make a review of the diagnosis and its development of MM from laboratory examination, diagnosis criteria and classiifcation.

AIM To establish the HPLC fingerprints of flavonoids in Ziziphi spinosae Semen and to determine the contents of two constituents.METHODS With spinosin as a reference peak,the HPLC fingerprints of ten batches of samples were established.The analysis of methanol extract of flavonoids in Ziziphi spinosae Semen was performed on a 30 ℃ thermostatic Agilent TC-C18column (4.6 mm × 250 mm,5 μm),with the mobile phase comprising of acetonitrile-0.1％ acetic acid flowing at 1 mL/min in a gradient elution manner,and the detection wavelength was set at 280 nm.RESULTS There were ten common peaks in the HPLC fingerprints,eight of which (vicenin-Ⅱ,glucosylvitexin,isospinosin,spinosin,6'-pyridyloylspinosin,6'-p-hydroxybenzoylspinosin,6'-feruloylspinosin and 6'-p-coumaroylspinosin) were identified.Spinosin and 6'-feruloylspinosin showed good linear relationships within the ranges of 15.00-40.00 μg and 5.00-14.00 μg,whose average recoveries (RSDs)were 100.5％ (1.6％) and 100.4％ (1.6％),respectively.CONCLUSION This accurate,simple and reliable method can be used for the quality control of flavonoids in Ziziphi spinosae Semen.

Objective To provide reference on the difference in blood glucose metabolism between different mouse strains by comparing blood glucose changes under food and /or water deprivation.Methods C57BL/6J mice, BALB/c mice,and ICR mice used in this study were divided into four groups:control group, food deprivation group, water depriva-tion group and food &water deprivation group .Their blood glucose was measured within 12 hours under various stresses . Results and Conclusion There are different blood glucose regulation patterns in different mice strains .The blood glucose level of C57BL/6J mice is usually higher than that of the BALB/c and ICR mice, while the of blood glucose level BALB/c mice stays relatively stable , and the ICR mice have the widest range of blood glucose levels upon these stresses .Accord-ing to our data, the difference in blood glucose metabolism between different mouse strains should be taken into considera -tion in blood glucose related studies for proper interpretation and design of experiments .

Moxibustion,which is simple for manipulation and effective,has always been a very important way for external treatment.Acupuncture and moxibustion were complementary to each other sincc ancient times.but modem people usually only pay attention to acupuncture and neglect the usage of moxibustion.In this paper the importance of moxibustion is expounded briefly.

ABSTRACT:Objective To observe whether N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP)can inhibit rat silicotic fibrosis by regulating stimulatory G proteinα(Gαs)/inhibitory G proteinα(Gαi)signal.Methods Male Wistar rats were randomly divided into three groups (n=1 0 ):control 1 6-w group,silicosis 1 6-w group,and Ac-SDKP pre-treatment group.The pathological changes of the lung tissue was observed by HE staining;the expressions ofα-smooth muscle actin (α-SMA),Collagen Ⅰ,fibronectin (Fn),Gαs,Gαi2 ,Gαi3 and cAMP were detected by Western blot.Immunofluorescence was performed on lung tissue sections to detect the coexpression ofα-SMA/Gαi3 . Results Within silicosis 16-w group,HE staining showed that the silicotic nodule volume increased,nodule fusion and the formation of interstitial fibrosis could be seen,and cell fibrous nodules were visible.Immunofluorescence staining showed the enhanced coexpression ofα-SMA/Gαi3 in fibrosis area.Compared with those in control group, the expressions ofα-SMA,Collagen Ⅰ,Fn,Gαi2 and Gαi3 significantly increased in silicosis 1 6-w group,but the expressions of Gαs and cAMP decreased.Compared with silicosis 1 6-w group,Ac-SDKP pre-treatment group had alleviated lung injury and decreased coexpression ofα-SMA/Gαi3 .The expressions ofα-SMA,Collagen Ⅰ,Fn,Gαi2 and Gαi3 protein significantly decreased in Ac-SDKP pre-treatment group,while the expressions of Gαs and cAMP increased obviously.Conclusion Ac-SDKP can regulate the expressions of Gαs and Gαi and promote the formation of cAMP,thus playing an effective role against silicotic fibrosis.
