In recent years,studies committed to the myeloproliferative neoplasms (MPN) pathogenesis suggest that potential somatic genetic alterations,and epigenetic events might contribute to MPN development,influence the MPN disease phenotype,progression,and promote transformation.The most relevant mutations identified so far can be broadly classified into two main groups.Mutations associated with dysregulated JAK-STATsignal transduction pathway,including mutations in JAK2,CALR,MPL,CBL,LNK,SOCS.Mutations in several epigenetic modifiers,including mutations in TET2,ASXL1,IDH1/2,DNMT3A,EZH2 and so on.In this paper,the abnormal clones and clonal evolution of MPN were reviewed.

Methods A multicentral opened clinical trial was conducted. 2 006 BPH patients were enrolled in the trial, in which 5mg epristeride was orally administered twice a day. Results After 4 months therapy, IPSS score was averagely decreased 6.12(28.8%) ( P

[Objective]To investigate the methord of nursing care of patients with cervical fracture-dislocation and spinal cord injuries during the perioperative period.[Method]Fifty-six patients with cervical fracture-dislocation and spinal cord injuries experienced preoperative training,psychology nursing and posture exercise,and postoperative position nursing and founctional exercising.The improvement of spinal cord founction was observed.[Result]All patients were followed up from 6 to 31 months,with an average of 17.6 months.According to JOA scores,the preoperative scores was from 0 to 13,with an average of 7.76 points.The postoperative score was 6-17 with an average of 10.3.The relief rate was 68.5%.Satisfaction rate was 74.1%.[Conclusion]The perioperative nursing is important for preventing and lessening complications,achieving good operative effect and promoting rehabilitation.

BACKGROUND:Recent studies have found that femoral neck angleαin patient with femoral neck hernial fossa increased significantly. However, whether the femoral neck hernia fossa can be used as imaging diagnostic indicator for femoroacetabular impingement syndrome remains controversial. OBJECTIVE:To evaluate the association between alpha angle and herniation pit in asymptomatic hip joints, influencing factors of the above indexes, and to provide evidence for the diagnosis of hip impingement syndrome. METHODS:Adults with asymptomatic hip joints from September 2013 to December 2015 were retrospectively studied. Alpha angles were measured on oblique axial MRI images. The incidence and size of herniation pit were determined by MRI. Size measures, prevalence, and statistical analyses were conducted regarding its association with age, gender, laterality (right or left hip). Intra-and inter-observer consistency was determined by intra-class correlation coefficient. RESULTS AND CONCLUSION:(1) 105 patients with asymptomatic hips were included, and 185 sides of hip MRI images were obtained. The range of age was 18-80 years old. The prevalence of herniation pit in asymptomatic hips was 21.6%. (2) The range of alpha angle was 27.6°–65.0°. Alpha angles of hip joints of 17 cases were ≥ 55°. (3) There was no association between alpha angle≥55° and the size of herniation pit (P>0.05). The prevalence of herniation pit was not correlated with age, gender and affected side (P=0.160, 0.157, 0.110). Inter-observer consistency of alpha angle was 0.523 between first measurements of first vs. second observer, respectively. Intra-observer consistency of alpha angle was 0.654, respectively. (4) There is no association between alpha angle ≥ 55 degrees and presence of herniation pit or demographic variables (age, gender and affected side). The presence of herniation pit and the increased alpha angle need to be interpreted with caution. Clinical symptoms and other examinations should be used in the diagnosis of hip impingement syndrome.

Objective To explore the molecular effect and interaction among nephrin, podocin, CD2AP and ?-actinin-4. Methods Firstly, the recombinant RNA interference (RNAi) plasmid-psiRNA-hH1GFPzeo, specifically targeting to the mRNA of nephrin, podocin, CD2AP or ?-actinin-4, was respectively tansfected into the mouse podocyte clone (MPC5) to each knockdown (KD) the expression of nephrin, podocin, CD2AP or ?-actinin-4. Molecular distributions were revealed by confocal microscopy, and the mRNA and protein expressions were detected with semi-quantitative RT-PCR and Western blotting. Results (1)In podocin KD group (siPod966 and siPod54), the mRNAs of podocin and nephrin were not detected, their protein decreased 92% and 79%, 82% and 67%, respectively. The mRNA and protein level of CD2AP increased 62% and 42%, 71% and 46%, respectively, whereas ?-actinin-4 did not change. In nephrin KD group (siNep492), the mRNA expression and protein level of nephrin were not detected, CD2AP increased 35% and 48%, respectively; and whereas podocin and ?-actinin-4 did not change. In CD2AP KD group (siCda744 and siCda21), the mRNA of expression CD2AP was not detected, and its protein level decreased 92% and 83%, the mRNA and protein of nephrin decreased 60% and 48%, 76% and 72%, respectively; podocin increased 38% and 22%, 56% and 44%, respectively; whereas ?-actinin-4 did not change. In ?-actinin-4 KD group (siAct1790 and siAct319), the mRNAs expression of ?-actinin-4 and nephrin decreased 69% and 58%, 64% and 49%, respectively; their protein level decreased 81% and 55%, 71% and 64%, respectively. However, the mRNAs of podocin and CD2AP increased 50% and 34%, 45% and 28%, respectively; and their protein level increased 64% and 46%, 65% and 42%, respectively. (2) With their expression change, the distributions of nephrin, podocin and CD2AP shifted evidently from the cell membrane surface to the nucleus circumference, whereas ?-actinin-4 showed no change, which was still localized in the cytoplasm and further extended to foot processes. Conclusion (1) Nephrin might more independently play a crucial role in the slit diaphragm complex. (2) Alpha-actinin-4 might interact direcdy or indirectly with nephrin, podocin and CD2AP. (3) The relationship among these podocyte molecules might not be spontaneous, either a single-directional or bi-directional reaction. (4) The normal localization of these podocyte molecules might depend on their normal expression quantity.

Objective To dynamically observe the expression of slit diaphragm complex molecules, including nephrin, podocin, CD2AP, and cytoskeleton protein a-actinin-4, in adriamycin-induced nephrotic (ADN) rats, and to further explore the molecular behavior of podocyte proteins during the occurrence and development of proteinuria and their possible mechanisms. Methods Adriamycin nephropathy was induced by a single tail intravenous injection of adriamycin. Renal tissue samples were collected at day 3, 7, 14, and 28, respectively. The distribution, mRNA expression and protein expression of nephrin, podocin, CD2AP and a-actinin-4 were examined by indirect immunofluorescence, real-time PCR and Western blotting, respectively. Results (1) After the adriamycin injection, a significant increment of the 24-hour urinary protein was observed at day 14 and persisted up to day 28 (P
