AIMTo explore the effect of propofol preconditioning on cardiomyocyte apoptosis and cytochrome C release from mitochondria during mild hypothermic ischemia/reperfusion in isolated rat hearts.

METHODS50 isolated SD rat hearts perfused on Langendorff apparatus were randomly divided into 5 groups (n=10): control group (C), DMSO group (D), 3 different concentrations of propofol groups of 25 micromol x L(-1) (P1), 50 micromol x L(-1) (P2), 100 micromol x L(-1) (P3) propofol respectively. All of the isolated rat hearts were subjected to 31 degrees C mild hypothermic ischemia for 55 min followed by 60 min reperfusion. The D, P1, P2, P3 groups were preconditioned by perfusing with K-H solution containing 20 micromol x L(-1) DMSO and 25, 50, 100 micromol x L(-1) propofol respectively for 10 min and then followed by 5 min K-H solution washing out before ischemia. The preconditioning procedure was repeated twice. Hemodynamics of the hearts was recorded after equilibration(baseline values) immediately before ischemia, 30 min and 60 min after reperfusion respectively. Cardiomyocyte apoptosis rate and contents of cytosolic and mitochondrial cytochrome C were measured at the end of reperfusion.

RESULTSAfter 30 min and 60 min reperfusion, LVEDP was significantly lower and LVDP was significantly higher in P3 group than those in C group ( P < 0.05, P < 0.01). Compared with C group, cardiomyocyte apoptosis rate of the hearts decreased significantly in P2,P3 groups at the end of reperfusion (P < 0.05, P < 0.01). Cytochrome C level increased significantly in mitochondria but decreased significantly in cytosol in P2, P3 groups as compared with C group (P < 0.05, P < 0.01).

CONCLUSIONPropofol preconditioning decreased cardiomyocyte apoptosis, protected the heart against 31 degrees C mild hypothermic ischemia/reperfusion injury by attenuation of the release of cytochrome C from mitochondria to cytosol.

Objective To evaluate the risk factors of developing post-engraftment hemorrhagic cystitis (HC) in patients receiving allogeneic stem cell transplantation (allo-HSCT).Methods Retrospective data was collected from 92 patients with acute leukemia (acute myeloid leukemia 41 and acute lymphoblastic leukemia 51) who underwent allo-HSCT from 2000 to 2010,and the association of pre-transplantation parameters with the incidence of post-engraftment HC was analyzed.Results Forty-three patients had HLA-matched donors and 49 had unrelated donors.Of these patients,25 developed HC at a median of 35 days (day +20 to +65) after allo-HSCT.In the univariate analysis,unrelated donor,gender mismatch (female donor to male recipient),conditioning containing busulfan,graft-versus-host disease (GVHD),prophylaxis with cyclosporine (CSA) + methotrexate (MTX) + mycophenolate mofetil (MMF),use of anti-thymoglobulin (ATG) and development of GVHD were associated with increased incidence of HC.In the multivariate study,gender mismatch (P =0.001),use of ATG (P ＜ 0.001),and GVHD (P =0.007) remain as independent factors for the increased risk of HC.More importantly,with these 3 factors,it is able to classify patients into 4 groups with risk of postengraftment HC at (7.7±4.6) ％,(22.9±7.1) ％,(48.2±10.5) ％,and 100.0 ％,respectively.Conclusion This retrospective study identified the gender mismatch,use of ATG in the preparation regimen,and aGVHD as important risk factors to predict the development of post-engraftment HC.Based on these risk factors,it is possible to classify patients into different risk groups for post-engraftment HC.Prospective study with a large cohort of patients is warranted to confirm the findings.Future clinical trial for HC prevention and treatment must be carried out on the intermediate and high-risk patients.

We herein reported a 27-year-old woman with a right renal mass for two years. She underwent laparoscopic partial nephrectomy. Immunohistochemical examination of the specimen confirmed the diagnosis of solitary fibrous tumor by revealing its positive staining for cluster of differentiation (CD)34, epithelial membrane antigen (EMA), B-cell lymphoma-2 (Bcl-2) and CD99 in the tumor cells. No adjuvant treatment was carried out. The patient was in good health without local recurrence or metastasis during 2 years of follow-up. Laparoscopic partial nephrectomy for renal solitary fibrous tumor is an alternative treatment to radical nephrectomy. It can provide a good outcome. However, further follow-up and more cases of renal solitary fibrous tumor treated with laparoscopic partial nephrectomy are necessary to compare the oncological outcome with radical nephrectomy.

OBJECTIVETo construct tissue-engineered neural complex in vitro and study its effect in repairing acutely injured spinal cord in adult rats.

METHODSNeural stem cells were harvested from the spinal cord of embryo rats and propagated in vitro. Then the neural stem cells were seeded into polyglycolic acid scaffolds and co-cultured with extract of embryonic spinal cord in vitro. Immunofluorescence histochemistry and scanning electron microscope were used to observe the microstructure of this complex. Animal model of spine semi-transection was made and tissue-engineered neural complex was implanted by surgical intervention. Six weeks after transplantation, functional evaluation and histochemistry were applied to evaluate the functional recovery and anatomic reconstruction.

RESULTSThe tissue-engineered neural complex had a distinct structure, which contained neonatal neurons, oligodendrocytes and astrocytes. After tissue-engineered neural complex was implanted into the injured spinal cord, the cell components such as neurons, astrocytes and oligodendrocytes, could survive and keep on developing. The adult rats suffering from spinal cord injury got an obvious neurological recovery in motor skills.

CONCLUSIONSThe tissue-engineered neural complex appears to have therapeutic effects on the functional recovery and anatomic reconstruction of the adult rats with spinal cord injury.
