BACKGROUND:So far, engineered myocardium is stil facing many problems. Research has demonstrated that bone marrow mesenchymal stem cells can be differentiated into myocardial cells. Polyglycolide and polycaprolactone are commonly used artificial polymers, which have good biocompatibility.
OBJECTIVE:To observe the growth of the poly(glycolic acid)/poly(e-caprolactone) copolymer patch in vitro in normal myocardium and infarcted myocardium.
METHODS:Bone marrow mesenchymal stem cells in Sprague-Dawley rats were separated using adherent separation and selection method, cultured in vitro. The third passage was labeled with DAPI. The bone marrow mesenchymal stem cellsuspensions (2×106/cm2) were produced and planted on poly(glycolic acid)/poly(e-caprolactone) copolymer scaffolds to form poly(glycolic acid)/poly(e-caprolactone) copolymer patch. After culturing for 48 hours, the specimens were observed under electron microscope, stained with hematoxylin and eosin, and then observed under light microscope. Rat models of myocardial infarction were established by ligating left anterior descending coronary artery. Poly(glycolic acid)/poly(e-caprolactone) copolymer patch was implanted into the normal and infarcted myocardium for 5 weeks. The survival of bone marrow mesenchymal stem cells was determined by the detection of pathology.
RESULTS AND CONCLUSION:Results of light microscope and electron microscope demonstrated that bone marrow mesenchymal stem cells grew three-dimensional y on poly(glycolic acid)/poly(e-caprolactone) copolymer patch. cells and patch were adhesive wel . Under laser confocal microscopy, compared with the first week, bone marrow mesenchymal stem cells were marked by DAPI in the myocardium at the fifth week. There were bone marrow mesenchymal stem cells marked by DAPI in the infracted area. Results of hematoxylin-eosin staining exhibited that bone marrow mesenchymal stem cells were detected in the infarct area. These results suggested that bone marrow mesenchymal stem cells adhered to the poly(glycolic acid)/poly(e-caprolactone) copolymer stent wel . The complexes of poly(glycolic acid)/poly(e-caprolactone) copolymer and bone marrow mesenchymal stem cells can be used for reparation of myocardium.

Over-expression of APP and Swedish mutation could cause some familial early onset AD. In this study, a primary screening was conducted of effective small interference RNAs (siRNAs) targeted wild type APP (APPwt) and Swedish mutant APP (APPswe). One siRNA targeting APPwt and the other siRNA targeting APPswe were designed. All these siRNAs were endogenously expressed by siRNAs expressing plasmids. COS-7 cells were transiently co-transfected with APP-GFP recombinant plasmids and siRNA expression vector. The silencing effect of each siRNA was quantitatively assessed by the level of expression of green fluorescent protein (GFP). It was found that the siRNAs silenced APPwt and APPswe to different degrees. siRNA directed against APPswe was more effective in suppressing the expression of fusion gene of APPswe than that of APPwt. The silencing effect of siRNA directed against APPswe indicating allele-specific silencing property of the siRNAs. Therefore, siRNAs directed against APP play an important role both in the therapeutic study of Alzheimer disease and functional exploration ofAPP gene.

OBJECTIVETo explore clinical characteristics and treatment of posterior Pilon fracture.
METHODSFrom January 2011 to January 2013,18 patients with posterior Pilon fracures were treated. Among them, 13 were male and 5 were female, aged from 22 to 63 years old, with an average age of 46. All the patients were closed fractures. Open reduction and internal fixation were performed after swelling subsided, lateral malleolous and posterior Pilon fracture were exposured through lateral approach on healthy side, plates were used to fixed,screws or small plates were used to fix the posterior prominence of medial malleolus after changed to supine position. AOFAS scoring were applied to evaulate clinical effects.
RESULTSAll patients were followed up with an average of 22(ranged, 12 to 48)months. All patients obtained satisfactory reset except one patient. All factures were recovered well with an average healing of 11 weeks. According to AOFAS score at the final following up, 7 cases were excellent,2 cases were moderate, and the total score was 86.8±9.2.
CONCLUSIONPosterior Pilon fracture is not rare in clinical, its mechanism of injury, traumatic anatomy, surgical procedure and prognosis are different from that of classical ankle fracture and Pilon fracture.

Objective To assess the diagnostic value of MRI on multiple focal nodular hyperplasia (FNH) of the liver. Methods MR images of 9 cases with pathological-confirmed multiple FNH were retrospectively analyzed. MRI features of the lesions were correlated with pathological findings. Results Multiple FNH was considered in all these 9 cases. Among them, the primary diagnosis was FNH in 5,hepatic adenoma in 3 and fibrolamellar hepatocellular carcinoma in 1 case. A total of 31 lesions were detected in the 9 cases. On T2WI, 19 lesions presented slightly high-signal intensity, and the other 12 presented iso-signal intensity. On T1WI, 12 lesions presented slightly low-signal intensity, 7 presented iso-signal intensity, and the other 12 presented high-signal intensity. On opposed-phase, the signal intensity of 1 lesion dropped unevenly. After bolus injection of contrast agent Gd-DTPA, in hepatic arterial phase 18 lesions showed mild to marked heterogeneous enhancement, 11 showed marked homogeneous enhancement, 1 showed moderate ring-like enhancement, and the last one did not have obvious enhancement In portal venous and delayed phase, all the lesions turned to iso- or slightly high-signal intensity gradually. Sixteen of 31 lesions presented central scar, which demonstrated mild star-like enhancement in delayed phase. Conclusion Multiple FNH presented certain MRI features, which contributed to the preoperative diagnosis.

Aim To observe the effects of the transient receptor potential vanilloid receptor 1 ( TRPV1 ) antago-nist Capsazepine on the LPS-induced fever process. Methods Three doses of Capsazepine were respec-tively injected into rats’ lateral ventricles before the in-traperitoneal injection of LPS caused fever. An emitter was implanted inside the rat’ s abdominal cavity to mo-nitor the body temperature changes during the fever process. Then the changes of calcium ion in the hypo-thalamus were detected by fluorescence and the expres-sions of TRPV1 protein were detected by Western blot. Results The higher dosage of Capsazepine was injec-ted, the higher the level of LPS-induced fever was, and the lower the concentration of calcium ion in the hypothalamus as well as the TRPV1 expressions were. Conclusion Capsazepine could increase the level of fever induced by LPS via acting on the rats’ hypothala-mus. This effect might be related to the functions of TRPV1 .
