Objectives To observe the changes of magnetic resonance imaging(MRI) during the course of treatment in hepatolen-ticular degeneration (HLD) and to evaluate its related factors.Methods Sixty - three patients with HLD received routine SE sequence MRI of brain and liver.Twenty - two patients with abnormal MRI in 42 patients and each of them had 2-4 times of serial MRI ex-aminations at interval of 1.0- 1.5 year.Results Ten patients had lesion in both brain and liver in 22 patients. Nine patients only in brain, 3 patients in liver.The major lesions disappear or decrease after rational treatments. There were only slight or no changes of MRI abnormalities in patients receiving treatments or age of patients was over 15 year old. Abnormal MRI findings shown again after stopped treatments over 2 months. In such cases, the clinical and MRI improvements were slow.The rate of clinical and MRI improvement in patients with adequate treatment were markedly higher than patients with inadequate treatment.Conclusions Liver and brain lesion will show in MRI disappear after adequate treatment;There are only slight or no change or showing again in MRI abnormalities in pa-tients with inadequate treatments compared with poor clinical improvement. MRI is beneficial to understanding therapeutic effect and prognosis of HLD.

Objective To observe the expression of matrix metalloproteinases(MMP)-1,MMP-3 and iNOS in cartilage of experimental rabbit osteoarthritis at different time intervals after anterior cruciate ligament transection(ACLT)operation.The aim of this study is to provide the theoritical evidence for using ACLT rabbit model in Osteoarthritis(OA)research.Methods Unilateral ACLT was performed on 27 randomly selected while rabbits and underwent unilateral arthrotomy was performed on the other 9 white rabbits as the control group.Nine randomly selected white rabbits in experimental group were killed and 3 white rabbits in the control group at 4th,8th and 12th week respectively.Cartilage degradation of femoral condyles was evaluated macr-oscopically,mRNA expression level and protein expression level of MMP-1,MMP-3 and iNOS was measured by reverse transcription-polymerase chain reaction(RT-PCR)and immunohistochemistry respectively.Results Forepart OA cartilage degradation was observed at the 4th week and became more severe at the 8th week after ACLF.Afterpart cartilage degradation was evident at the 12th week after ACLT while cartilage still remained normal in the control group,mRNA expression level and protein expression level of MMP-1.MMP-3 and iNOS were increased at the 4th week and became higher gradually at the 8th,12th week after ACLT compared with the control group.Expression distribution of MMP-1,MMP-3 and iNOS bad different patterns respectively.Conclusion It is suggested that the process of OA cartilage degradation can be simulated by ACLT model and MMP-1,MMP-3 and iNOS may be good markers in therapeutical research of OA.

ObjectiveTo study the effects on growth characteristics of cells mutated by outer space. Methods5 tumor cell lines and 1 bio-pharmaceutical cell line were carried in the recoverable satellite No.18 and returned after 18 days flying in outer space.The cell living systems were utilized in passive carrying. Some survival cells were monocoloned, and the experimental methods such as cell morphological observation,MTT assay and FACS were used for analysis of cell growth characteristics. ResultsThe survival cell rates of tumor cell lines and bio-pharmaceutical cells were markedly different. Compared with the control group, mutated cells appeared to have multiple cell morphological changes and the cell number of G1 phase was increased markedly (P<0.05). Growth rate in mutated cells were varied without specific discipline. ConclusionEffects of outer space on growth characteristics were complicated and multiplex in mutated cells,which were not all heredity in further passage. The differences of the monoclonal cell lines provide the potential to obtain optimizing cell lines by screen.

Background It is well known that sclera remodeling occurs during axial elongation in myopia under the control of growth hormone or its downstream effectors.The role of transforming growth factor-β (TGF-β) in myopia has been determined in previous studies.Bone morphogenetic protein (BMP) is one of members of the TGF-β superfamily,but if it plays an important role in the genesis and development of myopia is not completely clear.Objective This study was to identify the presence of BMPs in normal guinea pigs sclera and investigate the change of BMPs in the sclera in form-deprivation myopia (FDM) of guinea pigs.Methods Thirty young guinea pigs were randomized into normal control group and experimental group using table of random number.FDM models were established by occluding unilateral eyes of guinea pigs with a translucent lens for 14 days in the experimental group,and the fellow eyes served as the controls.Diopter of all eyes was tested by retinoscopy optometry,and ocular axial length was measured by A-sonography before and after modeling.Posterior sclera tissue of the animals was obtained on 14 days,and the relative expression level of BMPs mRNA and protein were assayed by reverse transcription PCR (RT-PCR) and Western blot.The use and care of the animals complied with ARVO Statement.Results On 14 days after occluding of unilateral eyes,the refraction diopter of the experimental group was (-0.48±0.51) D,and that of the fellow eyes was (3.22 ±0.34) D,showing a significant difference between them (t =-12.814,P =0.000).Also,a significant difference in the diopter was seen between the experimental group and normal control group ([-0.48±0.51]D vs.[2.97±0.70]D,t =-11.878,P=0.000).Axial length was (8.30 ± 0.05) mm in the experimental group,(8.11 ±0.06) mm in the fellow eyes and (8.06±0.06) mm in the normal control group,showing a significant increase in the experimental group compared with the fellow eyes and normal control group (t =7.230,P =0.000 ; t =9.084,P=0.000).The expressions of BMP-2 mRNA,BMP-4 mRNA,BMP-5 mRNA in posterior sclera were detected in the normal guinea pigs.Fourteen days after the induction of myopia,the relative levels of BMP-2 mRNA and BMP-5 mRNA in sclera were 0.41 ± 0.11 and 0.65 ± 0.06 in the experimental eyes,which were significantly lower than 0.62 ± 0.07 and 0.84 ± 0.03 in the fellow eyes with the descent range of 34.48% and 23.67% respectively (t=2.838,P=0.017; t=2.524,P=0.028).The relative values of BMP-2 protein and BMP-5 protein were 0.44±0.06 and 0.70±0.05 in the experimental eyes,and those of the fellow eyes were 0.61±0.05 and 0.82±0.03,showing significant decline in the experimental eyes with the lowing range of 23.42% and 15.21%,respectively (t =2.465,P =0.030;t =2.445,P=0.031).No significant differences were found in the expression of BMP-4 mRNA and protein in posterior sclera between the experimental eyes and the normal control eyes (mRNA:t =0.704,P=0.460;protein:t=0.987,P=0.365).Conclusions The expressions of the BMP-2 and BMP-5 in sclera down-regulate significantly in FDM eyes,which suggest that BMP-2 and BMP-5 participate in sclera remodeling during myopia induction.
