OBJECTIVETo investigate the effect of miRNA-101 on the expression of the enhancer of zeste homolog 2 (EXH2) in human androgen-independent prostated cancer LNCaP cells.

METHODSWe divided LNCaP cells into a blank control, a negative control, and a miRNA-l01 transfection group, constructed the vector by transfecting synthetic miRNA-101 mimics into the LNCaP cells, and evaluated the efficiency of transfection by fluorescence microscopy. Then we determined the expression level of EZH2 mRNA by qRT-PCR in the three groups of cells and that of the EZH2 protein in the negative control and transfection groups by Western blot.

RESULTSGreen fluorescence signals were observed in over 70% of the LNCaP cells in the transfection group after 24 hours of transfection. At 72 hours, the expression of miRNA-101 was significantly upregulated in the transfected cells (P < 0.01), that of EZH2 mRNA was remarkably lower in the transfection group (0.01 ± 0.10) than in the blank control (0.95 ± 0.40) and negative control (0.86 ± 0.30) groups (both P < 0.01), and that of the EZH2 protein was increased in the negative control but decreased in the transfection group with the extension of culture time.

CONCLUSIONmiRNA-101, with its inhibitory effect on the expression of EZH2 in LNCaP cells, is a potential biotherapeutic for prostate cancer.

Objective To observe the pathologic features on cardiac allograft and to test archived endomyocardial biopsy specimens for antibody-mediated rejection specific marker-C4d deposition and its characteristics by using immunoperoxidase (IP) techniques. Methods From January 2003 to December 2007,10 recipients underwent orthotopic cardiac transplantation and 17 specimens of endomyocardial biopsy were obtained either for a protocol basis (generally at 1 st month,3rd month,1st year and 2nd year post-transplant) and on immediate clinical indications.All specimens of endomyocardial biopsy were collected for histopathological examination and C4d immunohistochemical staining,simultaneously. All pathological diagnoses were done according to 2004 International Society for Heart and Lung Transplantation (ISHLT) recommendation working formulation and AMR Schema,and C4d staining intensity were graded and recorded as 0 to 3 +.Results Except 1 specimen unqualified,all 16 consecutive specimens of endomyocardial biopsy were qualified.There were 4 cases of acute T cell-mediated rejection (all graded 1 ),2 cases of Quilty lesion,and 7 cases of antibody-mediated rejection,who were documented according to ISHLT Schema and C4d deposition.Meanwhile,there were 6 cases showing evidence of antibody-mediated rejection without concurrent acute cellular rejection and only one case concordant with acute T cell-mediated rejection.One case of antibody-mediated rejection died 20 months posttransplantation due to combined transplant coronary artery disease (TCAD). The C4d in the cardiac allograft was deposited in microvasculature diffusively.Conclusion Antibody-mediated rejection is an important clinical entity following orthotopic heart transplantation and is difficult to diagnosis except to perform endomyoeardial biopsy.Immunoperoxidase staining for C4d is a sensitive and specific technique for detecting one marker of antibody-mediated rejection.

Objective To explore the clinical significance of sinus heart rate turbulence (HRT)and heart rate variability (HRV) in patients with chronic obstructive pulmonary disease(COPD).Methods The 59 moderate to severe COPD patients and 30 healthy subjects were enrolled in this study. The 24-hour holter monitor was used to screen the HRT onset (TO), turbulence slope (TS)and HRV. Pulmonary function tests and echocardiographic examination were performed for measuring left ventricular ejection fraction (LVEF), right atrial dimension (RAD), right ventricular dimension (RVD), right ventricular wall thickness (RVWT). Then all the parameters were compared between NC group and COPD group, and the relationship between HRT and HRV was investigated. Results Compared with control group, TO was significantly increased [(-0.2±1.1) % vs.(-3.8±2.8) %, t=6. 830,P＜0.01] and TS was decreased [(7.0±3.6) ms/RR vs. (11.7±6.1) ms/RR, t =3. 866, P＜0.01] in COPD group. In time domain HRV parameters, normal RR intervallerinin standart deviation(SDNN), standard deviation of normal-to-normal beats index (SDNNi), standard deviation of the averages of normal sinus to normal sinus (SDANN), mean squared differences of the successive RR intervals (rMSDD), fraction of consecutive normal sinus intervals that differ by more than 50 ms (PNN50) were significantly lower in COPD group than in control group(P＜0. 05). TO was negatively correlated with SDANN and rMSDD (r=-0. 369, P＜0. 05; r=-0.472, P＜0.01).TS was positively correlated with SDNN, SDANN and PNN50 (all P＜0.05), but had no correlation with rMSDD (P＞0. 05). Conclusions HRT and HRV are dramatically blunted in COPD patients.Combination of HRV and prognosis. and HRT may be simple and elegant ways for evaluating cardiac autonomic functions.

Objective To establish a simple and sensitive method for the determination of serum copper by spectrophotometry.Methods Nitro-PAPS was used as a coloring agent for serum copper in the presence of surfactants Tween-80 and Triton X-100 and the formed complex was measured by spectrophotometry.Results The maximum absorption wavelength of the complex was 570 nm and the molar absorption coefficient was 7.95?10~4 L/(mol?cm).The lineafity of the method was up to 63.0 ?mol/L and the recoveries ranged from 98.6% to 103.1%.The within-run and between-run CVs were 2.1%-3.3% and 2.7%-3.8%.The method(Y)was compared with an AAS method(X)and a correlation of Y=1.01X -0.27(r=0.998 2)was obtained.A reference interval(x~-?2s)determined with this method on 68 individuals was 9.7-24.1 ?moL/L.Conclusions A simple and sensitive method for serum copper has been established.It may used for the analysis of serum copper in clinical laboratories.

Background:The overlap of autoimmune liver disease with extrahepatic autoimmune disease adds the difficulty of diagnosis. It is essential to understand their clinical features. Aims:To analyze the clinical characteristics of primary biliary cirrhosis-autoimmune hepatitis( PBC-AIH ) overlap syndrome, and to investigate the effect of extrahepatic autoimmune disease on PBC-AIH. Methods:The clinical data including general information,clinical manifestations, biochemical parameters,immunological parameters,liver histopathological features,imaging findings and incidence of extrahepatic autoimmune disease of 81 patients with PBC-AIH were retrospectively analyzed. According to whether overlapping with extrahepatic autoimmune disease,PBC-AIH patients were divided into combination group and non-combination group. The clinical characteristics of the two groups were analyzed. Results:The ratio of male to female of 81 patients with PBC-AIH was 1 ∶ 9. 1,and the average age was(58. 1 ± 9. 9)years old. Of the patients 53. 1% had symptoms,the percentage of jaundice and pruritus was 18. 5% . Serum levels of ALT,AST,ALP,GGT,TBil and Glo were increased in all patients and IgG and IgM levels were increased in most of the patients. The positive rates of ANA, AMA and/ or AMA-M2,SMA and gp210 and/ or sp100 were 100% ,90. 1% ,1. 2% and 11. 1% ,respectively. Portal lymphoplasmacyte infiltration and interface hepatitis were the major liver histopathological features;50. 6% of the patients had both histological features of PBC and AIH. Cirrhosis was diagnosed in 28 patients(34. 6% )by imaging,and abdominal lymph nodes enlargement was found in 76 patients(93. 8% ). Twenty-three patients(28. 4% )overlapped with extrahepatic autoimmune disease;Sjogren’s syndrome and autoimmune thyroid disease were the most frequently overlapped extrahepatic autoimmune diseases. The level of GGT was significantly lower in combination group than in non-combination group(P = 0. 001). No statistically significant differences in other clinical characteristics were found between the two groups. Conclusions:It is crucial to understand the clinical characteristics of PBC-AIH and to screen the overlapped extrahepatic autoimmune disease,especially Sjogren’s syndrome and autoimmune thyroid disease.
