This article introduces the genes related to pathogenesis and prognosis of myeloproliferative neoplasms (MPN) and the current situation of MPN domestic and overseas,which have been reported in the 56th ASH annual meeting.It is emphasized on essential evaluation of the risk score using IPSET in ET,Tefferi in PV and DIPSS-plus in PMF separately.It has assessed advancements in allogeneic hematopoietic stem cell transplantation,phlebotomy,cytoreductive therapy and drug therapy.The article pays more attention to aspirin,anagrelide,JAK2 targeted agent ruxolitinib and thalidomide which is domestically used in the treatment of PMF.

As an important indicator of total hip arthroplasty (THA) the rate and degree of offset reconstruction play an important role in improving the prognosis and life quality of patients. The reconstruction of femoral offset is closely related to reserved length of calcar femorale, the head and neck length of prosthesis, angle degree of neck shaft and whether lower limb is isometric. Reconstruction strategy includes making a meticulous and standard measurement before the surgery, predicting the reserved length of calcar femorale, selecting a prosthesis with approximate anatomical neck-shaft angle and reconstructing offset by adjusting the head and neck length of the prosthetic during the operation. The aim of this article was to introduce the research progress and influence of offset on hip function, prosthetic wear and postoperative complications such as pain, limp and unequal leg length, and to discuss the reconstruction strategy.

The Au-PDA-Fe3O4 decorated graphene oxide electrode was modified with Prussion blue-secondary antibodies for determination of cancer biomarker α-fetoprotein (AFP) with great sensitivity.Scanning electron microscopy (SEM), X-ray diffraction (XRD) and ultraviolet-visible absorption spectrometry were used to characterize the structure of the material.Greatly enhanced sensitivity for the cancer biomarker is based on a dual signal amplification strategy.First, Fe3O4-PDA-Au used for the biosensor platform increased the surface area to capture a large amount of primary antibodies (Ab1), which resulted in amplification of the detection response.Second, graphene oxide allowed several binding events of PB-Ab2.Enhanced sensitivity was also achieved by introducing the multibioconjugates of Ab2-PB-GO onto the electrode surface through sandwich immunoreactions.The test result shows that there are linear relationships between current and AFP concentrations ranging from 0.005 ng/mL to 1 ng/mL and 1 ng/mL to 20 ng/mL, with the low detection limit (LOD) of 1.0 pg/mL.This immunosensor is simple, low-cost and sensitive and shows a great potential in biomedicine, clinical diagnosis and health examination.

Objective To analyze and summarize the skills and complications of extracorporeal membrane oxygenation( ECMO) cannu-lation and vein intubation. Methods The clinical data of 21 patients of V-A or V-V ECMO in our hospital from January 2009 to July 2014 were analyzed retrospectively. And the techniques of different catheter sites were summarized. Results Three cases were successfully insert-ed catheter by jugular vein puncture with one time. Four patients with ascending aorta intubation died from uncontrolled severe hemorrhage. Eight peripheral catheter site had a small amount of bleeding,with no more bleeding after pressurized bandage. There were no complications like bleeding, hematoma, hemothorax and pneumothorax in the period of ECMO. Conclusion In the process of the ECMO catheter, the standardized operation could reduce the incidence of serious complicaions including bleeding.

AIM: To observe the effects of some component of Chinese herbs for external use on proliferation of human umbilical vein endothelial cells (HUVEC) and investigate the mechanism of promoting tissue repair. METHODS: The method of MTT was used to examine the effects of Rg1, Rh1, perlolyrine, cinnamyl aldehyde, muscone, astragalus polysaccharin (APS), velver antler polypeptide (VAP) and soluble extract of boswellia carterii birdw (BCB) on proliferation of HUVEC. RESULTS: APS did not promote proliferation of HUVEC at 9.75 mg/L-2.5 g/L; Rh1 promoted proliferation of HUVEC at 1.94 mg/L-0.5 g/L (P

Objective To report the first case of cutaneous type adult T-cell leukemia/lymphoma(cATLL) in China. Methods The skin lesion was examined by histopathology and direct immunofluorescence (DIF), and the immunophenotype was also studied. ELISA and Western blot were used to test the serum antibodies to HTLV-Ⅰ, and HTLV-Ⅰproviral DNA of lymphoid cells was detected by PCR. Results The patient had polymorphic skin lesions including papules, plaques, and bullae with tense or flaccid walls. Histopathogical examination showed subepidermal bullae, and there were small-to-medium-sized atypical lymphoid cell infiltrations in the dermal papilla in the bottom, and border of the bulla. CD45+ and CD45RO+ staining, and negative DIF were observed in the atypical lymphoid cells. The serum antibodies to HTLV-Ⅰ, and proviral DNA of HTLV-Ⅰin the blood lymphoid cells were detected. The patient died with a disease course of one year and ten months. Conclusion ATLL is not extremely rare in China, and cATLL may also exist.

Objective To research the therapeutic effect of vitamin E in prevention and treatment of anemia in premature children.Methods We investigated 90 cases of premature children admitted to the neonatal ward of our hospital from December 2010 to December 2011.According to hospital successively order these premature were randomly divided into control group (Group A),high-dose group (Group B),low-dose group (Group A).Group A including 30 cases,subcutaneous injection of erythropoietin(EPO) from the 7th days after admission,750IU/kg weekly for 3 times,for 4 weeks.At the same time,plus iron 6mg/(kg·d).On the basis of the above-mentioned control treatment,oral administration of different doses of vitamin E was in the treatment group,for 4 weeks.Group B including 30 cases was given vitamin E 15mg/(kg·d).Group C including 30 cases was given vitamin E 2.5mg/(kg· d).The changes of each group during the treatment in hematocrit (Hct),hemoglobin(Hb),red blood cell(RBC),reticulocyte(Ret) and the changes of serum concentrations of vitamin E before and after treatment were observed.Results Hct,Hb,RBC,Ret in group B,group C patients were both improved.The improvement of the indicators was better than that of group A (P ＜ 0.05).There was no significant difference between the improvement of each index of Group B and Group C(P ＞ 0.05).Serum concentrations of vitamin E after treatment in group B and group C patients were significantly higher and the difference was statistically significant(P ＜ 0.05).Serum concentration of vitamin E in group A didn't increase obviously.Conclusion Additional small doses of VitE should be given during EPO prevention of anemia in premature children.

OBJECTIVE: To investigate the pathological factors of syndrome pathomechanism through studying the correlation between syndromes of posthepatitic cirrhosis and biological parameters. METHODS: Clinical information of three hundred and fifty-five patients with posthepatitic cirrhosis was collected and the database was established. Parameters with statistical significance were analyzed with multi-factor regression analysis to investigate the main influencing factors of the syndromes of posthepatitic cirrhosis. RESULTS: Formulae of six syndromes, including syndrome of yin deficiency of liver and kidney, syndrome of damp heat, syndrome of stagnated heat smoldering, syndrome of yang deficiency of spleen and kidney, syndrome of stagnation of liver qi and spleen deficiency and syndrome of blood stasis due to qi deficiency, were established with stepwise regression analysis. CONCLUSIONS: One of the pathophysiological bases of syndrome of blood stasis due to qi deficiency in cirrhosis is synthetic dysfunction of hepatocytes. The pathophysiological basis of syndrome of damp heat is inflammatory injury, which is also syndrome of stagnated heat smoldering in cirrhosis patients. The relationship between syndrome of yin deficiency of liver and kidney and stasis and damp heat may be the pathophysiological basis of the posthepatitic cirrhosis..
