20 normal males were examined by BIODEX isokinetic test and rehabilitation system,and data collected were used to observe the influence of angle and time on the isokinetic concentric constriction of knee joint. It was found that angle and time, especially angle factor obviously affected the testing results.

OBJECTIVETo explore the effect of Sedum sarmentosum Bunge Extract (SSBE) on severe acute pancreatitis (SAP) induced acute lung injury (ALI) model rats and their excessive inflammatory reactions.
METHODSForty-two healthy adult male Sprague-Dawley (SD) rats were randomly divided into 3 groups, the sham-operated control group (C), the SAP group (SAP), and the SSBE treated group (SSBE), 14 in each group. SAP induced ALl rat model was induced by retrograde injection of 5% sodium taurocholate (1 mL/kg) into the pancreatic duct. SSBE (100 m/kg) was administrated subcutaneously after the establishment of the SAP model. Equal dose of SSBE was injected again 12 h later. Equal volume of normal saline was administrated in the same way for rats in the C group and the SAP group. Rats were sacrificed after successful modeling and samples taken at 12 and 24 h. Pathological changes in the pancreas and the lung tissue were observed under light microscope. The ascites, serum amylase (AMS), wet/dry proportion (W/D) of the lung tissue, activities of myeloperoxidase (MPO), interleukin-1 (IL-1), IL-6, and tumor necrosis factor-alpha (TNF-alpha) were also measured.
RESULTSAscites and serum AMS activities significantly increased; MPO, IL-1, IL-6, TNF-alpha contents, and W/D ratio also significantly increased in the SAP group, when compared with the C group (P<0.05). Compared with the SAP group, those parameters were all attenuated in the SSBE group at 12 and 24 h (P<0.05, P<0.01). Pathological changes in the pancreas and the lung tissue were alleviated in the SSBE group under light microscope. The injury degree ranged between that of the C group and the SAP group.
CONCLUSIONSSBE could relieve the ALl in SAP model rats, which could be achieved through alleviating inflammation responses of SAP rats.

5.Acute renal failure after hematopoietic stem cell transplantation-review.
Journal of Experimental Hematology 2009;17(4):1118-1122
Hematopoietic stem cell transplantation is a common procedure for the treatment of hematologic malignancies and some non-malignant hematologic disorders. In addition to other transplant-related organ toxicities, acute renal failure is a common complication following allogeneic hematopoietic stem cell transplantation. This review discusses the incidence, etiology, risk factors, and prognosis of renal failure associated with three commonly used transplantation models: myeloablative autologous, myeloablative allogeneic, and non-myeloablative allogeneic hematopoietic stem cell transplantations.

OBJECTIVEPPAR-gamma is associated with the differentiation, apoptosis, proliferation and cytokine secretion of immunologic cells. This study investigated peripheral blood lymphoblastic PPAR-gamma mRNA expression and its correlation with plasma IL-13 contents in children with acute idiopathic thrombocytopenic purpura (ITP).
METHODSFifty-three children with acute ITP who were in line with the standard test between September 2007 and July 2008 were enrolled. Fifty healthy children during the same period were used as the control group. PPAR-gamma mRNA expression in peripheral blood lymphocytes were detected by RT-PCR. Plasma IL-13 contents were detected using ELISA.
RESULTSPPAR-gamma mRNA expression in peripheral blood lymphocytes from acute ITP children were significantly higher than that in the control group (0.78 +/- 0.03 vs 0.52 +/- 0.05; P< 0.05). Plasma IL-13 contents in children with acute ITP were also significantly higher than those in the control group (160.21 +/- 34.26 pg/mL vs 121.42 +/- 12.69 pg/mL; P< 0.05). There was a positive correlation between plasma IL-13 level and lymphoblastic PPAR-gamma mRNA expression in children with ITP (r=0.89, P< 0.05).
CONCLUSIONSPPAR-gamma mRNA expression in peripheral blood lymphocytes increased and were positively correlated with plasma IL-13 contents in children with acute ITP, suggesting that PPAR-gamma and IL-13 might participate in the pathogenesis of acute ITP.

OBJECTIVETo investigate the risk factors for anastomotic infectious complications after bowel resection in patients with Crohn disease.
METHODSClinical data of 124 patients with Crohn disease undergoing bowel resection between January 1990 and October 2012 were analyzed retrospectively. The risk factors were identified by χ(2) test and Logistic regression.
RESULTSFourteen patients (12.3%, 14/114) developed anastomotic infectious complications in the postoperative period, including anastomotic leak (n=7), intra-abdominal abscess (n=6), and enterocutaneous fistula (n=1). Crohn disease activity index (CDAI)>150 (OR=2.185, 95%CI:1.098-6.256, P=0.040), steroid usage (OR=2.674, 95%CI:1.118-8.786, P=0.027), and the presence of preoperative abscess/fistula (OR=3.447, 95%CI:1.254-10.462, P=0.014) were identified as independent risk factors of anastomotic infectious complications. In the absence of these 3 risk factors, the rate of anastomotic infectious complication was 5.7% (3/53), which increased to 11.4% (4/35) when one risk factor was present, 21.1% (4/19) when two risk factors were present, and 42.9% (3/7) when all the 3 risk factors were present.
CONCLUSIONSCDAI>150, steroid usage and preoperative abscess/fistula are associated with higher rates of anastomotic infectious complications following bowel resection for Crohn disease. A prudent management should be carried out if risk factors can not be eliminated preoperatively.

BACKGROUND: Spinal lamina reimplantation assisted hollow screw laminoplasty has achieved good clinical efficacy. The search literature found that there is no research at home and abroad on the biomechanical properties of unilateral and bilateral hollow screw fixation. OBJECTIVE: To evaluate the biomechanical property of different fixation with hollow screws in artificial and goat vertebrate laminoplasty. METHODS: A laminoplasty was conducted by using hollow screws. Based on the artificial vertebrate laminoplasty model, new models were generated by simulating unilateral screws fixation with a depth of screw insertion 5 mm (A group), unilateral screw fixation with a depth of screw insertion 8 mm (B group) and bilateral screw fixation with a depth of screw insertion 5 mm (C group). Based on the goat vertebrate laminoplasty model, new models were generated by simulating unilateral screws fixation (A group) and bilateral screw fixation (B group). The pull-out strength and static pressure were tested in the biomechanical testing machine with a sensor. RESULTS AND CONCLUSION: (1) In the artificial vertebrate model, the average pull-out strength of the group B was stronger than that of the groups A and C (P < 0.01); the average pull-out strength of the group A was stronger than that of group C (P < 0.01), the difference was statistically significant (P < 0.05). However, the average static compression of the group A and group B was similar; the average static compression of the group C was lower than that of the groups A and B, and the difference was statistically significant (P < 0.01). (2) In the goat vertebrate model, the average pull-out strength and static compression of the group A were stronger than that of the group B, and the difference was statistically significant (P < 0.05). (3) Results suggest that unilateral screw fixation in the artificial and goat vertebrate laminoplasty can provide sufficient pull-out strength and static compression, and the biomechanical strength is positively related to the depth of the screw.
