Objective To observe the effect of intra-articular injection of berberine on the expression of matrix metalloproteinase (MMP)-13,ADAMTS-5,Aggrecan and Collagen Ⅱ in the cartilage of rabbits with osteoarthritis.Methods Thirty male New Zealand White rabbits underwent bilateral anterior cruciate ligament transection (ACLT).On the basis of randomization one knee of each rabbit was treated with 0.3 ml 100 μmol/L berberine resolved in the normal saline (NS) (the experimental group) and the other knee was treated under the same schedule using NS (the placebo group) 4 weeks after transection,once a week for five weeks.Nine weeks after ACLT,all rabbits were killed and the knee joints were evaluated by histology and biochemistry.The mRNA expression of MMP-13,ADAMTS-5,Aggrecan and Collagen Ⅱ in the cartilage was analyzed using reverse transcription polymerase chain reaction (RT-PCR).All data were analyzed using Student's t test.Results Mankin histological evaluation showed that the extent and grade of cartilage damage in the experimental group (6.9±1.9) were less severe than the placebo group (9.3±1.2)(t=3.394,P＜0.01).The mRNA expression of MMP-13 and ADAMTS-5 decreased (160±54;166±47) (t=3.311,P＜0.01;t=2.651,P＜0.05) while that of Aggrecan (261±50) and Collagen Ⅱ (335±64) increased in cartilage compared to the placebo group (233±45;234±67;186±64;254±69),the differences were significant (t=2.941,P＜0.01;t=2.743,P＜0.05).The content of hydroxyproline (Hyp) and glycosaminoglycan (GAG) in cartilage [(23.5±2.8) μg/mg;(30±3) μg/mg] increased significantly in the experimental group (t=2.941,P＜0.01;t=2.743,P＜0.05) compared to the placebo group [(19.9±2.8) μg/mg;(27.4±2.9) μg/mg].Conclusion Berberine protects against cartilage degradation and inhibits the progression of osteoarthritis by suppressing MMP-13 and ADAMTS-5 expression.

Objective To elucidate the relationship between LYVE-1 and VEGF-C and their expression in laryngeal squamous cell carcinoma(LSCC),and provide theoretic evidence for the judgement of metastasis and prognosis of LSCC,also for the treatment.Methods An immunohistocbemical analysis was performed to 50 specimens of LSCC with lymphatic endothelial marker LYVE-1.Quantitation of lymphangiogenesis growth factor VEGF-C by RT- PCR was performed to 30 specimens of LSCC.Finally the correlation between LVD and VEGF-C mRNA was analyzed with statistics methods.Results LYVE-1 (+) was observed in all LSCC.The median copy number of VEGF-c mRNA was 4-5-fold higher in LSCC than in adjacent normal tissue.There was correlation between tumor VEGF-C mRNA copy number and intratumoral LVD.Conclusion Lymphatic vessels existed in LSCC.There was correlation between high levels of LVD in LSCC than in normal tissue.The high level of VEGF-C may accelerate the lymphatic metastasis by promoting the proliferation of lymphatic vessel.

Objective To investigate whether velocity vector imaging (VVI) combined with stress echocardiography could detect potential myocardial impairment of the left ventricle(LV) in diabetic rats.Methods DM rats ( n = 18,administered by STZ at 65 mg/kg) and control rats( n = 12) were performed with VVI and M-mode echocardiography both at rest and after dipyridamole stress 12 weeks later. Twodimensional echocardiographic cine loops and M-mode images of three consecutive beats were obtained from the short-axis views at the mid-LV level. The means of segmental peak systolic velocity(Vs), circumferential strain(εc) ,radial strain(εr), systolic circumferential and radial strain rate (SRc, SRr) and the percent wall thickening (WT% ,derived from M-mode) were obtained. After echocardiograms were performed,the hearts were excised and prepared for HE staining and ultrastructural observations under electron microscopy.Results At rest,only SRc in the DM group was significantly lower than that in the control group( P ＜0.05), the other parameters were statistically comparable between the two groups. After dipyridamole stress,all VVI values in the DM group were significantly lower than those in the control group ( P ＜0.05).However,there was no significant difference in WT% between the two groups either at rest or after dipyridamole stress ( P ＞0.05). Conclusions The VVI parameters combined with dipyridamole stress are more effective in evaluating potential myocardial impairment of the LV walls in diabetic rats. SRc might be more sensitive indices that can be used to detect myocardial impairment at rest.

Objective To observe the morphologic protection effect of intra-articular injection of osteoprotegerin (OPG)on articular cartilage in a rabbit model of osteoarthritis (OA).Methods Sixty male New Zealand rabbits were randomly divided into 3 groups:OPG group (n=20),sham-operated group (n=20) and PBS group (n=20).In OPG group and PBS group,each rabbit underwent anterior cruciate ligament transection (ACLT) in left knee joint,then 0.1 ml OPG solution or PBS were injected into the left knee for 8 weeks (5 times a week) in OPG group and PBS group,respectively.In sham-operated group,the anterior cruciate ligament was just exposed without transection,and then the incision was closed.All rabbits were sacrificed 12 weeks after operation,and the left knee joints were obtained.The Pelletier score and Mankin score were used to evaluate the macroscopic and microscopic cartilage morphology.Results The score of femoral condyle cartilage and tibial plateau cartilage was 1.80±0.89 and 1.80±0.77 in OPG group,respectively,and 3.10±0.97 and 3.20±0.77 in PBS group.However,there was no statistical difference in Pelletier score between the sham-operated group and the OPG group.Consistent with the macroscopic data,the OPG group has a significantly lower Mankin score involving cartilage structure (2.65±0.88),chondrocyte (1.35±0.71),Safranin O staining (1.83±0.83),tidemark integrity (0.30±0.47) and total score (6.13±1.97) compared with the PBS group (4.52±1.09,1.85±0.63,2.80±0.75,0.65±0.49,and 9.83±1.98,respectively).The OPG group has a significantly higher total Mankin score compared with the sham-operated group (4.80±1.25),however,there were no statistical differences in four subitem scores between the two groups.Moreover,the cartilage thickness in OPG group was 371.84±38.94 μm,255.09±74.82 μm in PBS group,and 404.68±15.97 μm in the sham-operated group,and the differences were statistically significant between three groups.Conclusion OPG has a protective effect on articular cartilage and can slow the progression of OA by reducing the grade of synovitis,decreasing the volume of osteophytes,and suppressing the loss of cartilage thickness.
