ObjectiveTo compare costs of combined intravenous and inhalation anesthesia (CIIA) and total intravenous anesthesia (TIA) when lower limbs orthopedics (LLO) performed on cerebral palsy children (CPC).MethodsTo analyze data of 49 CPC who received LLO under CIIA and TIA,and compare costs of two anesthetic styles.ResultsTIA had a significantly lower cost than CIIA (P<0.001),and showed a lower incidence of post-operation nausea and vomiting.ConclusionTIA can decrease cost of anesthesia and post-operation nursing compared with CIIA.

Objective To screen for differential expression of genes in bone marrow mesenchymal stem ceils (MSCs) stimulated by electromagnetic fields (EMFs) and to study the mechanism of differentiation of the bone mar- row MSCs induced by EMFs.Methods Mouse bone marrow MSCs were isolated and cultured in vitro.The third- passage cells were stimulated by EMFs,then the total RNA was extracted,purified to cDNA and reversely transcribed to yield a cRNA probe.The cRNA probes from stimulated and control cells were labelled with Cy5 and Cy3,respec- tively.The two samples were hybridized with a mouse oligo microarray,and the hybridization signals were scanned. The reverse transcriptase polymerase chain reaction (RT-PCR) was used to identify the interesting genes:Duspl and Rabl.Results A total of 153 differentially expressed genes were found comparing the stimulated group and the control group.There were 74 up-regulated genes and 79 down-regulated genes in the stimulated group.Semi-quantita- tive RT-PCR confirmed that the Duspl and Rabl mRNA expression levels of the stimulated group were up-regulated. Conclusion The gene expression profiles of the bone marrow MSCs were altered after EMF exposure.The genes are involved in cell proliferation and differentiation,transcription control,metabolism and response to stress.These re- sults provide deeper insight into the mechanism of differentiation of the bone marrow MSCs.

2', 3', 5'-Tri-O-acetyl-N6-(3-hydroxylaniline)adenosine (WS070117) is a derivative compound of natural product cordycepin. It has significant lipids regulating activity and low toxicity which has been proved by in vitro and in vivo experiments. In this study, 1H NMR-based metabolomics was used to investigate the dose-related effects of WS070117 on hyperlipidemia of high-fat-fed hamsters. The hyperlipidemic hamsters were administrated with six different doses of WS070117, including 3, 12, 50, 100, 200 and 400 mg x kg(-1) x d(-1). 1H NMR spectra of hamster serum were visually and statistically analyzed using two multivariate analyses: principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA). As a result, WS070117-treated groups showed dose-related regulation of metabolites associated with lipid metabolism, choline metabolism and glucose metabolism. The dose of 3 mg x kg(-1) x d(-1) of WS070117 only exhibited a little lipids regulating activity. However, the doses of 12 and 50 mg x kg(-1) x d(-1) of WS070117 both regulated the contents of metabolites to reverse significantly toward normal levels. When the dose of WS070117 reached 100 mg x kg(-1) x d(-1), it was more effective than positive control drugs. The work suggested that NMR-based metabolomics might be a valuable approach to evaluate dose-related effects of lipids regulating compounds.

ObjectiveTo assess the safety and efficacy of retrograde ureteroscopy lithotomy (URSL)assisted antegrade percutaneous nephrolithotomy (PCNL) for complex upper ureteral calculi in semisupine-lithotomy position.MethodsFrom March 2007 to December 2010,a total of 95 patients with complex upper ureteral calculi underwent retrograde URSL assisted antegrade PCNL in semisupine-lithotomy position.Ureteral calculi size was 12 mm × 6 mm to 38 mm × 15 mm,24 cases combined with renal calculus.Firstly retrograde URSL was performed,once the stone fragments moved up to renal pelvis,a 16-22 F PCNL working channel was established under the ultrasound guidance through which lithotripsy was performed using an ureteroscope.Finally a 6-7 F double-J tube was indwelled.ResultsOperations were successfullycompleted in 93 patients.However,in it 2 patients were converted to open surgery because of significantureteral distortion due to previous open surgery.Operative time was(42.7 ± 14.9) min; estimated blood loss was(34.5 ± 26.1 ) ml.The ureteral calculi clearance rate was 100.0％,and renal calculus clearance rate inthose combined with renal calculus was 95.8％ (23/24).There were no major intraoperative and postoperative complications excepted early urinary leakage in 2 cases and fever ≥39℃ in 3 cases.ConclusionsRetrograde URSL assisted antegrade PCNL in semisupine-lithotomy position is safe and feasible for complex upperureteral calculi,especially non-opaque calculi,combined with renal calculus,easily ascending ureteral calculi and large calculi burden which has low calculi clearance rate after URSL.The outcomes are encouraging with fewer complications.It also avoids intraoperative change of patient's position.

BACKGROUND:Smooth muscle cells and transitional epithelial cells were traditionally used to construct tissue-engineered bladder and to perform double-sided implantation of scaffold.However,double-sided implantation is difficult to perform,because smooth muscle cells are difficult to isolate or culture in vitro and passage is limited.OBJECTIVE:To verify the feasibility of tissue-engineered bladder reconstruction with bone marrow mesenchymal stem cells(BMSCs)and bladder acellular matrix(BAM).DESIGN:A basic empirical study.SETTING:Linbaixin Medical Research Center,Second Affiliated Hospital,Sun Yat-sen University.MATERIALS:Experiments were performed at the Linbaixin Medical Research Center,Second Affiliated Hospital,Sun Yat-sen University from March 2006 to Mav 2007.The laboratory was the Opening Laboratory of Hospital Affiliated to Health Department of China.One-month old SD rats of either sex,weighting 80-100 g were provided by Animal Experimental Center of Sun Yat-sen University.Fresh porcine bladders were offered by Animal Experimental Center of Southern Medical University.METHODS:Whole bone marrow culture and successive adherence method was used to culture rat BMSCs in vitro.Flow cytometry was employed to detect surface antigen.Eradicator washing method was applied to prepare porcine BAM and measure its purity and characteristies.Third passage of BMSCs were inoculated in BAM and cultured in a medium containing vascular endothelial growth factor(VEGF165)(25 ng/L)in vive and in vitro to test compatibility.Cells cultured alone were considered to be controls for the in vivo trial,and materials non-implanted with cells were considered to be controls for in vitro trial.Suitable microenvironment was simulated to induce the differentiation of BMSCs.Four weeks and eight weeks later,compound materials were respectively removed to perform tissue section test.Simultaneously,immunohistochemistry keratin staining was conducted to examine regeneration of epithelial cells.MAIN OUTCOME MEASURE:Biocompatibility of BMSCs and BAM.RESULTS:①BMSCs were cultured by whole bone marrow method.Flow cytometry demonstrated that third passage of cells were positive for CD29(99.43%).②BAM had good biological characteristics.Homogen matrix and byssoid collagen appeared under a microscope.Compatibility trials showed good compatibility of BMSCs and BAM and well-growth cells.③Four weeks later,histological section test confirmed inflammatory cell infiltration,closely-arranged collagen and elastic fiber.Immunohistochemistry keratin staining showed lamellar and discontinuous simple epithelium.Eight weeks later,no inflammatory cell infiltration was found,and closely-arranged collagen and elastic fiber were detected.Immunohistochemistry keratin staining showed lamellar and continuous multiple epitheliums.CONCLUSIoN:With good compatibility,BMSCs and BAM appear to be an ideal material for bladder tissue engineering.

OBJECTIVETo observe therapeutic effects of different therapies on intracerebral hemorrhage at acute stage.

METHODSOne hundred and twenty-five cases of intracerebral hemorrhage at acute stage were randomly divided into a combined treatment group, an acupuncture group, a Xingnaojing group and a routine treatment group, and effects of different treatment programs on the hematoma absorption velocity and nervous function defect scores were observed.

RESULTSAll of the treatment groups have obvious therapeutic effects for hematoma absorption and nervous function defect score, with the best therapeutic effect in the combined treatment group (P < 0.01, P < 0.05).

CONCLUSIONAcupuncture combined with Xingnaojing injectio is an effective therapy for intracerebral hemorrhage at acute stage.
