Objective To observe the clinical efficacy of percutaneous vertebroplasty (PVP) with percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral compression fracture(OVCF) by systematic review. Methods From September 2005 to March 2009,46 cases of fresh OVCF were treated. Patients were divided into 2 groups (A, B), according to Jikei grade, Genant semiquantitative method, injury vertebra number. Twenty-five cases(group A)were treated by PVP,8 males and 17 females with the age of 52 - 78 years (average 69). Vertebra segment of fracture was within T6 - L5 (14 in case thoracical vertebrae and 11 lumbar vertebrae). Twenty-one cases(group B)were treated by PKP,There were 6 males and 15 females with the age of 54 - 82 years (average 71). Vertebra segment of fracture was within T6 - L4 (12 in case thoracical vertebrae and 9 lumbar vertebrae). The clinical efficacy, incidence rate of complication, the anterior height of vertebrae body,visual analogue pain scale(VAS) ,ease of pain were measured preoperatively and at 6 weeks, 3 and 6 months and 1 year postoperatively between the two groups. Results All the patients were followed up for 12 -45 months with an average of 23.5 months. The average recovery of anterior height of vertebrae body was respectively(85.95 ± 4.31) % in group A and (93.64 ± 3.35) % in group B,which statistically difference in vertebral height between two groups (P < 0.05). No statistical significant difference was seen in VAS, analgesic durg (AID) and ease of pain complication between two groups (P >0. 05). Statistical significant difference was noted in pre-postoperatively between intra-two groups (P <0. 05). Conclusions PVP and PKP can quickly relieve pain and enhance vertebral stability in treating thoracolumbar OVCF according to evaluation parameter, and have the similar therapeutic efficacy in treatment of OVCF with minimal invasion. However, PKP is superior in the recovery of vertebral height.

Objective To test the hypothesis that IL-10 may promoting left ventricular remodeling and cardiac function by modulating extracellular matrix after acute myocardial infarction. Methods Male adult rats were randomly divided into three groups: control group (n=6) , MI/AAV2 group (n=16) and MI/AAV2-IL-10 group (n=16). Establishing animal modol of experimental myocardial infarction and recombinant adeno-associated virus type 2 (AAV)/IL-10 (AAV2-rhIL-10) and AAV2 were injected around the ischemic zone. Echocardiography parameters, hemodynamic parameters, left ventricular mass index (LVMI) , collagen volume fraction (CVF) , perivascu-lar circumferential area (PVCA) , collagen type Ⅰ & Ⅲ volume fraction and mRNA levels of collagen type Ⅰ & Ⅲ , matrix metalloproteinases-2 ( MMP-2 ) and tissue inhibitor of metalloproteinase-1 ( TIMP-1) were compared among the three groups. Results Improved cardiac function was observed in MI/AAV2-IL-10 group shown by echocardiography and hemodynamic examination. Four weeks after myocardial infarction, thickness of different parts of LV was not different in MI/AAV2-IL-10 group and MI/AAV2 group. Nevertheless CVF, PVCA and collagen type Ⅰ volume fraction was significantly descending in remote zone of MI/AAV2-IL-10 group compared with that of MI/ AAV2 group. The mRNA expression of collagen type I and MMP-2 was lower in MI/AAV2-IL-10 group than that in MI/AAV2 group. Conclusion Recombinant IL-10 expression mediated by AAV2-rhIL-10 transfection of rats' myocardium promotes LV remodeling and cardiac function after acute myocardial infarction. The promotion was partially achieved by inhibition myocardium collagen deposition.

Aim To investigate the effect of sphingo-sine kinase 1 (SphK1 )on unilateral ureteral obstruc-tion(UUO)-induced tubulointerstitial fibrosis and ex-plore the possible mechanism.Methods The CD-1 mice were randomly divided into four groups:sham-op-eration group(Sham),PF-543 treatment control group (Sham +PF-543),model group(UUO)and PF-543 treatment group(UUO +PF-543).On 1 ,3,7 and 1 4 d after operation,eight mice were selected randomly from each group and sacrificed.The protein expressions of SphK1 ,mature TGF-β1 ,FN,ColⅠ,LC3,Beclin1 ,Atg5 and Atg1 2 were observed by Western blot.The histo-logical changes were examined by Masson′s trichrome stain.Immunhistochemistry was performed to measure the levels of expression of SphK1 ,FN and Col Ⅰ. Transmission electron microscope was used to observe the autophagic body.Results SphK1 expression and autophagy were both upregulated in a mouse model of kidney fibrosis induced by UUO. Meanwhile, in-creased mature TGF-β1 and deposition of extracellular matrix(ECM)were observed in tubulointerstitial areas compared with sham-operated mice.After intraperito-neal injection with the SphK1 specific inhibitor PF-543 in UUO mice,enhanced expression of SphK1 and acti-vated autophagy were significantly abrogated.Howev-er,aggravation of renal fibrosis was detected when SphK1 inhibitor PF-543 was applied to suppress SphK1 expression in UUO mice.Conclusion SphK1 activa-tion is renoprotective through the induction of autoph-agy in the pathogenesis of kidney fibrosis.
