1 ? 25-dihydroxy-vitamin D3(1? 25 (OH)2 D3)induced differentiation of human promyelocytic leukaemia cells ( HL-60 ) into mature myeloid cells in vitro. The ratio of nuclei to cytoplasma decreased; Their nucleoli reduced; Cells became irrgular and extended the pseudopods. 1 ? 25 (OH ) 2 D3 caused significant increase of nitroblue tetrazolium ( NBT ) reduction and ?-non-specific acid esterase (?-NAE ) and acid phosphatase (ACP ) activities. These data and morphological characteristics suggest that HL-60 cells were conclusively identified as monocytes/macrophages. The histogram of DNA distribution ahylyzed by flow cytometry demonstrated G0 + G1 phase increased and S phase increased and S phase decreased remarkably after treatment with l?, 25 ( OH ) 2 D3 as compared with untreated cells.

MicroRNAs (miRNAs) are a novel class of small noncoding RNAs that regulate gene expression by targeting mRNAs for either cleavage or translational repression.Accumulated studies show that miRNAs aberrantly expressed in tumors are closely related with tumorogenesis and could be potential tumor biomarkers.It will be helpful in the diagnosis,prognosis and(or) predicting treatment response of tumor by imaging miRNAs expression.Several molecular imaging methods,including the optical imaging,radionuclide imaging and multimodality imaging,have been successfully used to visualize miRNAs,miRNAs,a new molecular imaging target,may explore a new field for tumor diagnosis and therapy.

Complete surgical resection is very important for the outcome of cancer treatment and prognosis.Radionuclide imaging and optical imaging are effective methods for intra-operative guidance of tumor exploration and resection because of their capability in accurate tumor localization and margin delineation.With the development of more specific molecular probes and more sensitive detectors,advanced imaging methods that combine the advantages of both optical and radionuclide imaging,such as Cerenkov luminescence imaging,will be expected to play a more important role as intra-operative navigating agents for surgical oncology in the near future.

Objective To investigate the effect of high-flux hemodialysis (HFHD) on advanced oxidation protein products (AOPPs) in maintenance hemodialysis (MHD) patients.Methods 40 MHD patients (MHD group),50 non-dialytic chronic kidney disease (CKD) patients (CKD group) and 31 healthy subjects undergoing health examination survey received AOPPs detection.After lowflux hemodialysis (LFHD) for 3 months,HFHD was performed in MHD group for 3 months.Plasma AOPPs and other biochemical indicators were tested at the end of 0,3 and 6 months.AOPPs levels were detected in HFHD and LFHD dialysates.Results Plasma AOPPs level was higher in MHD group than in CKD and control groups,and plasma AOPPs level was higher in CKD group than in control group.Compared with before LFHD in MHD group,AOPPs and triglyceride (TG) levels had no significant differences after LFHD for 3 months(t=0.831,-0.191,both P＞0.05),while plasma cholesterol (CHO) and β2 MG levels were increased in MHD group after LFHD for 3 months(t＝-2.697,10.39,P＜0.05 or 0.001).There were significant differences in plasma AOPPs,TG,β2-MG and CHO levels before versus after HFHD for 3 months (t=4.292,2.271,8.297 and 2.295,P ＜0.001 or 0.05).No AOPPs were detected in HFHD and LFHD dialysates.Conclusions Plasma AOPPs levels are increased in CKD patients.LFHD can not effectively eliminate AOPPs,while long term HFHD can decrease the plasma levels of AOPPs,TG and CHO,and reduce β2-MG accumulation.

Objective To analyze the clinical features of juvenile dermatomyositis (JDM) combined with soft-tissue calcification. Methods Forty-seven patients with JDM combined with soft-tissue calcification (soft-tissue calcification group) were retrospectively analyzed, and they were contrasted with 89 patients with non-calcification (non-calcification group). Results The rates of Gotton signe, muscle contracture and joint dysfunction in soft-tissue calcification group were significantly higher than those in non-calcification group:87.23% (41/47) vs. 43.82% (39/89) and 68.09% (32/47) vs. 21.35% (19/89), and there were statistical differences (P<0.05). The dosage of glucocorticoid (conversion of prednisone measuring more than 1.5 mg/kg), rate of using immunodepressant, level of creatine kinase in soft-tissue calcification group were significantly lower than those in non-calcification group:17.02%(8/47) vs. 68.54%(61/89), 25.53%(12/47) vs. 88.76%(79/89), (566.45±240.41) U/L vs. (1 680.12±656.50) U/L, and there were statistical differences (P<0.05). Conclusions The patients with JDM combined with Gotton signe are more prone to soft-tissue calcification. The rate of muscle contracture and joint dysfunction in soft-tissue calcification patients is significantly higher than that in non-calcification patients. For the patients whose creatine kinase are not obviously elevated, they are more prone to soft-tissue calcification. Early active application of glucocorticoid and immunodepressant therapy can reduce or prevent the occurrence or development of late calcium deposition.

Objective To explore the diagnostic value of hysteroscopy and transvaginal B-type ultrasound in endometrial polyps.Methods Eighty cases of endometrial polyps in our hospital from August 2015 to August 2016 were selected as the research subjects.Firstly,the patients were performed the transvaginal B-type ultrasound examination and then the hysteroscopic examination was conducted.The examination results of the two methods were observed.Results After hysteroscopic examination,75 cases were diagnosed as endometrial polyps,5 cases were misdiagnosed as other diseases.In the transvaginal B-type ultrasound examination,52 cases were diagnosed as endometrial polyps and 6 cases were misdiagnosed as other diseases.The detection rate had statistically significant difference between hysteroscopy and B-type ultrasound examination (P<0.05);the minimum was at least 1 endometrial polyp and the maximum were 4 endometrial polyps, including 21 cases of 1 endometrial polyp,36 cases of 2 endometrial polyps,14 cases of 3 endometrial polyps and 9 cases of 4 endometrial polyps.The hysteroscopic examination accurately detected 21 case(100.00%) of 1 endometrial polyp,34 cases (94.44%) of 2 endometrial polyps,12 cases (85.71%) of 3 endometrial polyps and 8 cases (88.89%) of 4 endometrial polyps;the transvaginal B-type ultrasound accurately detected 13 cases (61.90%) of 1 endometrial polyp, 17 cases (47.22%) of 3 endometrial polyps,11 cases (78.57%) of 3 endometrial polyp and 5 cases (55.56%) of 4 endometrial polyps,there were statistically significant differences in the distribution between the two examination methods (P<0.05),moreover hysteroscopy had higher accuracy.Conclusion The diagnosis efficiency of hysteroscopy in diagnosing endometrial polyps is significantly better than that of B-type ultrasound.
