BACKGROUND:Kienb?ck disease lacks of suitable animal models, which are similar to the pathological process of avascular necrosis of human lunate bone.
OBJECTIVE:To establish a new animal model of Kienb?ck disease using medical TH adhesive embolism and to explore the rationality of model establishment.
METHODS:A total of 30 healthy adult New Zealand rabbits, male or female, were selected. Using self-control method, the rabbits were randomly assigned to experimental sides and control sides. By dril ing in the center of the lunate bone, 0.2 mL of medical TH glue was injected three times. An equal volume of physiological saline was injected into the center of the lunate bone on the control side. X-ray examination, general observation, Micro-CT measurement of bone, and tissue pathology detection were conducted at 4, 8 and 12 weeks.
RESULTS AND CONCLUSION:Gross specimen, X-ray and histological results showed that ischemic necrosis of the lunate bone on the experimental side was visible at 8 weeks after model induction. The ischemic necrosis of the lunate bone became more typical at 12 weeks. Among the Micro-CT microscopic parameters of trabecular bone, trabecular bone density parameters bone volume fraction and the number of trabecular bone were significantly lower on the experimental side than those on the control side (P<0.05). Spatial parameters of trabecular bone significantly increased. Trabecular separation and structure model index on the experimental side were significantly greater than those on the control side. Results suggested that ischemic necrosis of the lunate bone appeared on the experimental side at 8 weeks after injection of medical TH glue. Rabbit models of ischemic necrosis of the lunate bone can be established at 12 weeks. Thus, alterations, which were similar to ischemic necrosis of human lunate bone, appeared, such as blood transportation damage in the lunate bone, trabecular bone fracture, and empty lacuna, when surrounding tissues were not obviously injured.

Objective To study the MRI manitestation of juvemle acute pure cartilage fracture of the knee joint.Methods The MRI changes of cartilage,subcartilage low signal line and subcartilage bone were analysed retrospectively in 26 juvenile patients with acute pure cartilage fracture confirmed by arthroscopy.Sagittal and coronal MRI scanning were performed in 26 patients.Using fast low angle shot fat saturation T_1-weighted image(FLASH-FS-T_1WI)sequences,spin echo T_1-weighted image(SE-T_1WI)and fast imaging with steady-state precession three dimensional fat saturation T_2-weighted image(FISP-3D-FS- T_2WI)sequences in sagittal plane,SE-T_1WI and multi echo data image combination T_2-weighted imaging (MEDIC or ME-T_2WI)in coronal plane.Using ME-T_2WI sequence,axial plane MRI scanning in 5 patients.Results Twenty-seven sites of 26 patients include 8 patella,7 femoral medial condyle, 11 femoral lateral condyle and 1 tibial plateau.Three types pure cartilage fracture were observed,totally defect of the cartilage in 7 sites(include 3 patella,2 femoral medial condyle,1 femoral lateral condyle and 1 tibial plateau),fissuring fracture in 3 sites(include 2 femoral medial and 1 femoral lateral condyles), superficial defect of the cartilage in 17 sites(include 5 patella,3 femoral medial and 9 femoral lateral condyle).Corpus liberum was found in 21 patients'knee joints by arthroscopy,but only 3 cases by MRI. Bone bruise was detected,and subcartilage low signal lines were normal.Conclusion Using FLASH-FS- T_1WI,SE-T_1WI,FISP-3D-FS-T_2WI and ME-T_2WI sequences,sagittal and coronal MRI scanning in femoral and tibial plateau pure cartilage fractures,and using ME-T_2WI sequence axial scanning in patella r cartilage fractures may show the position,extension and types of the acute pure cartilage fracture of the knee joint. MRI is the hest non-invasive method for studying cartilage fracture.

Objective To investigate the methylation status in the promoter region of Dickkopf-3 (Dkk3) gene in patients with myelodysplastic syndromes (MDS),and to initially explore the relationship between the methylation of this gene and survival time.Methods Methylation-specific PCR (MSP) was applied to measure the promoter methylation of Dkk3 gene in 43 bone marrow or peripheral blood samples of MDS patients.As controls,70 normal peripheral blood samples from general outpatients were examined.Results In 43 patients with MDS,7 patients (16.3 ％) showed Dkk3 gene methylation.And 5 of them were semi-methylation status,2 of them were exhaustive methylation status.In 70 controls,1 showed Dkk3 gene semi-methylation.The frequency of methylation in MDS patients was significantly higher than that of controls (x2 =8.93,P =0.005).In the Dkk3 methylation group,2/7 were from bone marrow and 5/7 were from peripheral blood.Meanwhile,2 patients were RA,1 patient was RCMD,4 patients were RAEB.There was no significant difference between the different sample source (bone marrow or peripheral blood) for the results of the methylation status (x2 =0.051,P =0.821).Either between the different sex,age,type,chromosome and WPSS score (P ＞ 0.05).The progress of disease didn't influence the methylation frequency (P ＞ 0.05).The smvival analysis showed no relationship between the methylation of this gene and smvival time.Conclusions In this MDS group,there is high level of methyl-modification in Dkk3 gene.The methylation of Dkk3 might be one of the molecular mechanisms that contribute to the progress of patients with MDS.The peripheral blood sample maybe a better substitute in detective of Dkk3 with MDS.

OBJECTIVE:To explore the effects of short-term application of atorvastatin combined with ezetimibe on efficacy and related indicators of patients with primary nephrotic syndrome with hyperlipidemia. METHODS:Data of 50 patients with prima-ry nephrotic syndrome with hyperlipidemia were retrospectively collected and divided into combination group and control group ac-cording different treatment,25 cases in each group. All patients received low-salt,low-fat ,high-quality protein,giving prednisone 1 mg/(kg·d),po,qd,combined with anticoagulation,diuretic,anti-infection,taking cytotoxic drugs if necessary. Based on it, control group received Atorvastatin calcium tablet 20 mg before going to bed,qd;combination group received Atorvastatin calcium tablet(the same dosage and usage with control group)+Ezetimibe tablet 10 mg,qd. They were treated for 2 weeks. Lipid-lowering efficacy and low-density lipoprotein(LDL-C),triglyceride(TG),cholesterol(TC),high-density lipoprotein(HDL-C),24 h uri-nary protein (M-TP),serum albumin,alanine aminotransferase (ALT),aspartate aminotransferase (AST),serum creatinine and blood urea nitrogen before and after treatment in 2 groups were observed and the incidence of adverse reaction was recorded. RE-SULTS:There was no significant differences in the total effective rate of Lipid-lowering in 2 groups(P>0.05). After treatment, LDL-C,TC and HDL-C in 2 groups were significantly lower than before,Alb in combination group and ALT in 2 groups were sig-nificantly higher than before,with statistical significance(P<0.05),while there were no significant difference in 2 groups(P>0.05). And there was no significant difference in the TG,M-TP,AST,serum creatinine and blood urea nitrogen before and after treatment(P>0.05). CONCLUSIONS:Atorvastatin combined with ezetimibe can improve the blood lipid of patients with primary nephrotic syndrome with hyperlipidemia,while showing similar efficacy and safety with atorvastatin alone in a short term.
