Objective To explore the effects of sports training on endothelin-1 ( ET-1 ) and endothelin-1 receptor (ETR) and its subtypes in the myocardium in rats. Methods After sports training, levels of endothelin-1 were measured using radioimmunoassay, and changes in ETAR and ETBR levels by radioligand binding assay. Results The endothelin-1 level in myocardial cells was significantly reduced ( P

Objective To evaluate the the brow position and shape in young Chinese women using a photography measurement.Methods A total of 100 Chinese women aged 20 to 30 years were photographed to determine the distance between brow and eye.Measurements were made from a horizontal plane through the lateral canthus of right eye to three vertical points on the upper brow margin at the medial canthus,lateral limbus of the iris,and lateral canthus.Results The distance between brow and eye in young Chinese women was 2.12,2.52 and 2.46 cm at medial canthus,lateral limbus of the iris and lateral canthus,respectively.The distances were higher between the brows and eyes at lateral limbus of the iris and lateral canthus than that at medial canthus (P＜0.05).Conclusions The measurement used in this study is a simple and practical quantitative method.The results can be used to guide the surgical choice and help to evaluate the surgical techniques.

Objective To confirm the safety and nutritional efficacy of high branched-chain amino acids through a pragmatic study allowing its use as an alternative to 15AA in patients with liver dysfunction. Methods The study was performed as a randomized, prospective trial. Eighty two patients with liver dysfunction undergoing operation were randomly assigned to receive high branchedchain amino acids or 15AA as part of their TPN regimens for 7 days. Daily parenteral intakes of energy nitrogen and lipid were equal in the two groups. Results Efficacy analysis showed that high branched-chain amino acids were as efficient as 15AA in avoiding protein catablosim. No serious adverse event was reported in the two groups. For hematology, renal, hepatic safety criteria and for the vital signs,no significant difference was observed between the 2 groups. No significant difference was observed concerning nitrogen balance and protein catablosim. For peripheral immunoglobulin and lymphocytes, a statistically significant difference was observed between the high branched-chain amino acids and the 15AA groups. Conclusion High branched-chain amino acids is new, safe and efficient amino acids for parenteral nutrition.

Objective To analyze the relationship between cytotoxic T cells Perforin level, IFN-γand IL-10 in patients with chronic hepatitis B. Methods After a short-term cultivation of peripheral blood collected from 50 patients with chronic hepatitis B, a flow cytometry was employed to detect the levels of Per-forin, IFN-γ and IL-10 in CD8~+ cells to compare with those of the health donors the HBV DNA copies in their blood were also measured by RT-PCR to analyze the relationship with Perforin, IFN-γ, and IL-10 in CD8~+ cells. Results In patients with chronic hepatitis B, the levels of Perforin, IFN-γ and IL-10 in CD8~+ ceils were (5.30 ± 2.62)%, (4.05 ± 2.25) % and (0.77 ± 0.50) %, respectively, which were statistical-ly lower than health donors(the t values were 4.50, 4.56 and 4.20 respectively; P < 0.01) ; Of 26 cases of chronic hepatitis B patients with HBeAg-positive Pefforin and IFN-γ in CD8~+ T cells were (4.54 ± 1.93) % and (3.32 ± 1.59)%, respectively, significantly lower than those of the 24 chronic hepatitis B patients with HBeAg-negative (the t values were 2.22 and 2.54, respectively; P <0.05) ; And the levels of Perforin, IFN-γ had a negative relation with the HBV DNA copies (the coefficient correlations-0. 539 and-0. 340; P < 0.01 and P < 0.05). Conclusion In patients with chronic hepatitis B, the reduced levels of Pefforin, IFN-γ and IL-10 may be related with the long-term existence of HBV, and the protracted course of disease.

Objective To study the value of MR three-dimensional volumetric interpolated breath-hold examination(3D-VIBE)and conventional MR imaging (including MRCP) in diagnosing cholangiocarcinoma early and evaluating the respectability of cholangiocarcinoma. Methods 20 patients with malignant obstruction of bile duct were scaned by conventional MR imaging(including MRCP) and dynamic-enhanced 3D-VIBE triple-phase acquisitions. MR imaging features of the tumors were analysed and the re-spectability of cholangiocarcinoma was also evaluated. The differences between conventional MR imaging and 3D-VIBE in displaying the tumors and the infiltration extent of the tumors were compared. Results The sensitivity ratio in showing the tumors were 85 and 95% with conventional MR imaging and 3D-VIBE, respectively, and there was statistically significant difference between two sequences in displaying infiltration of adjacent organs by the tumors(P<0.05). Conclusion 3D-VIBE is superior to conventional MR imaging in the early diagnosis,preoperative assessment of the infiltration extent and the tumor respectability of cholangiocarcino-ma.

Objective To detect serum level of anti-M-type phospholipase A2 receptor (PLA2R) antibody in elderly patients with idiopathic membranous nephropathy (IMN) and to explore its clinical significance in IMN disease.Methods A total of 134 patients with renal biopsy-proved glomerular diseases were enrolled in this study,including 42 elderly cases with IMN,45 non-elderly cases with IMN,19 elderly cases with minimal change nephropathy (MCN),12 elderly cases with IgA nephropathy (IgAN),8 elderly cases with hepatitis B-associated membranous nephropathy (HBV-MN) and 8 elderly cases with focal segmental glomerulosclerosis (FSGS).Western blotting was used to detect serum anti-PLA2R antibody and the correlation of anti-PLA2R antibody with laboratory parameters in elderly IMN patients was analyzed.Results The elderly and non-elderly patients with IMN showed that the positive rate of anti-PLA2R antibody was 71.4％ and 73.3％,respectively (P＞ 0.05).The positive rate of anti-PLA2R antibody in elderly IgA nephropathy,HBV-MN and MCN patients was 16.7 ％,12.5％ and 5.3％ respectively.Anti-PLA2R antibody was not detected in serum from elderly FSGS patients.The positive rates of serum anti-PLA2R antibody were significantly higher in both elderly and non-elderly IMN patients than in elderly patients with secondary MN and other types of glomerlonephritis (P ＜ 0.01).Furthermore,anti-PLA2R autoantibody level was positively correlated with 24-hour urine protein level and negatively correlated with the concentration of serum albumin in elderly patients with IMN (P＜0.01).Conclusions Anti-PLA2R antibody is a sensitive serological marker of IMN.Detection for anti-PLA2R antibody might be helpful for the diagnosis of both elderly and non-elderly IMN and for the monitor of IMN disease severity.

Hepatic eosinophilic granuloma (HEG) is a rare benign liver disease,which belongs to histocytosis.Preoperative diagnosis of HEG was difficult because its clinical manifestation was not characteristic.In this article,the clinical data of 1 patient with HEG who was treated at the Jinhua Municipal Central Hospital of Zhejiang Province in September 2012 were retrospectively analyzed,and the diagnosis,differential diagnosis and treatment for HEG were investigated.
