OBJECTIVETo investigate clinical effects of arthroscopy in the treatment of medial meniscal cyst.
METHODSFrom June 2011 to January 2013, 7 patients with medial meniscal cyst were treated with arthroscopy. There were 3 males and 4 females,ranging in age from 27 to 63 years old,with a mean age of (43.93±2.10) years old. The cysts have been discovered for 3 to 30 months,with a mean time of (10.6±1.3) months. All the patients complained of knee pain,especially in the medial joint gap. The Pisani sign, Caklin sign and medial McMurray sign were all positive. Preoperative MRI examination confirmed the diagnosis. Lysholm score changes and clinical efficacy were observed through a six-month follow-up.
RESULTSThe postoperative Lysholm scores were all significantly higher than the preoperative scores. According to Sarimo standard, 6 patients got an excellent result, and 1 good.
CONCLUSIONArthroscopic treatment of medial meniscal cyst has replaced the traditional method, which could retain the normal meniscus as much as possible and repair the meniscus injury simultaneously, as well as get a good curative effect and a good recovery of knee function. This method is worthy of clinical application.

OBJECTIVETo identify independent risk factors influencing the survival time of patients with chronic liver failure and construct a predictive model.
METHODSRetrospective analysis was applied to clinical data of 362 patients with chronic liver failure treated with artificial liver in Tianjin third centre hospital between May 2002 and May 2007. Data were analyzed with SPSS 13.0 statistic software, t test and rank test were used on quantitative data, chi-square test was used on qualitative data, Cox regression analysis was used to select the independent risk factors influencing the survival time. According to independent risk factors from Cox regression model, a prognostic model was established.
RESULTS1. Independent risk factors (P less than 0.05) influencing the survival time were: Child-Pugh score, bilirubin separation ALT, ascites, arginine, age, tyrosine and serum sodium. 2. By receiver operating characteristic curves (ROC) analysis, the area under ROC (AUR) to predict the outcome of chronic liver failure patients was 0.782, and the cutoff score was 27.69.
CONCLUSIONS1. Child-Pugh score, bilirubin separation ALT, ascites, arginine, age, tyrosine and serum sodium are independent risk factors affecting survival time of patients with chronic liver failure. 2. Cox model we constructed can reliably predict the survival time of patients with chronic liver failure.

OBJECTIVETo observe the anti-inflammatory effect of total saponins of Panax japonicus on LPS-induced RAW264. 7 macrophages.
METHODThe effect of total saponins of P. japonicus of different concentrations on RAW264. 7 cell viability was determined with the MTT method. The NO kit assay was adopted to detect the NO release of total saponins of P. japonicus to LPS-induced RAW264. 7 cells. The enzyme linked immunosorbent assay (ELISA) was used to detect the secretion of tumor necrosis factor-alpha (TNF-alpha) and interleukin 1-beta (IL-1beta). The reverse transeriptase-polymerase chain reaction (RT-PCR) was used to determine the expression of inducible nitric oxide synthase (iNOS) ,TNF-alpha,IL-1beta. The protein expression of nuclear transcription factor-kappaB p65 (NF-kappaB p65) was tested by Western blot.
RESULTThe safe medication range of total saponins of P. japonicus was less than 80 mg x L(-1). Compared with the LPS model group, total saponins of P. japonicus high, middle and low dose groups (0.1, 1, 10, 40 mg x L(-1)) could significantly reduce the secretion of NO, TNF-alpha, IL-1beta of LPS-induced RAW264. 7 cells, and inhibit the expressions of iNOS, TNF-alpha and IL-1beta mRNA and the protein expression of NF-kappaB p65.
CONCLUSIONThis study preliminarily proves the protective effect of total saponins of P. japonicus on LPS-induced RAW264.7 macrophages. Its action mechanism may be related to NF-kappaB signal pathway.

Objective To compare 99Tcm-MIBI MPI with delayed enhancement MRI (DE-MRI) in patients with idiopathic dilated cardiomyopathy (IDCM). Methods Forty patients with IDCM were included. They underwent both rest 99Tcm-MIBI myocardial perfusion imaging and DE-MRI within 7 days. 99Tcm-MIBI MPI was performed to identify diffuse or segmental abnormal perfusion patterns including reduced or defect perfusion segments. DE-MRI images were divided into 4 categories: no delayed enhancement, septal, subendocardial and transmural delayed enhancement, x2 test was used for data analysis. Results Diffuse and segmental perfusion abnormality on 99Tcm-MIBI MPI were found in 19 (47.5%) and 21 (52.5%)patients respectively, while DE-MRI enhancement was simultaneously found in 5 patients of the former (5/19, 26.3%) and 18 (18/21, 85.7%) of the latter (x2 =14.401, P<0. 001). For those (n=18) with both segmental perfusion abnormality and DE-MRI enhancement, the number of segments of the 4 DE-MRI respectively. A significant difference was found in the DE-MRI enhancement categories between normal and defect perfusion segments (x2 = 29. 183, P <0.001 ) and between reduced and defect perfusion segments as well (x2 =25. 110, P<0. 001). Conclusions Both diffuse and segmental perfusion abnormalities on 99Tcm-MIBI MPI can be found in patients with IDCM. DE-MRI enhancement is more frequently found in patients with segmental perfusion abnormality.
