Objective To investigate arterial blood gas(ABG)changes induced by different intra- abdominal pressures during CO_2 pneumoperitoneum in rabbits with lung and liver impact injury under controlled hemorrhage.Methods In this study 75 rabbits were randomized into nine groups(6 rabbits in each group)according to the amount of blood loss(6 ml/kg、12 ml/kg、22 ml/kg)and intra-abdominal pressures(5 mm Hg,10 mm Hg,15 mm Hg).After model was established successsfully,respiratory rates (RR),ABG and death rates were observed at pre-pneumoperitoneum,after 0.5 hour and 2 hours under pneumoperitoneum and 0.5 hour after desufflation.Results Without pneumoperitoneum,different blood loss exerted different effect on arterial blood gas:RR,PaCO_2 increased(P

Objective To investigate the effects of the sense and antisense testes-signal transduction and activator of RNA (T-STAR) gene on the colon cancer cell line HCT-116. Methods The sense and antisense T-STAR gene was stably transfected into HCT-116 cells with lipofectamine. The expression level of T-STAR in those cells was detected by Western blotting and the growth velocity and proliferation of those cells by cytokinetics. Results The growth velocity and proliferation decreased after transfection of the sense T-STAR gene, but increased after transfection of the antisense T-STAR gene. Conclusion T-STAR gene can inhibit the growth velocity and proliferation of HCT-116 cells.

Objective To investigate the changes of telomerase activity after knocking down endogenous expression of T-STAR (testes-signal transduction and activator of RNA) gene in human lung adenocarcinoma cell line A549 by antisense strategy. Methods The mRNA and protein expression of T-STAR gene were determined by RT-PCR and Western blotting, and the telomerase activity was measured by PCR-ELISA, after transfection of T-STAR antisense gene into A549 cells with lipofectamine. Sense pcDNA-STAR and blank pcDNA3.1 transfection served as control. Results The expression of T-STAR gene was significantly inhibited at mRNA and protein level, and the telomerase activity was significantly decreased. Conclusion The down-regulation of telomerase activity may result from inhibition of T-STAR gene expression in lung adenocarcinoma A549 cells.

Objective To analyze the protein expression in the rat hippocampus by the proteomic approach.Methods Proteins from hippocampal tissue homogenates of the rat were separated by two-dimensional gel electrophoresis(2-DE),and stained with colloidal Coomassie blue to produce a high-resolution map of the rat hippocampus proteome.Selected proteins from this map were digested with trypsin,and the resulting tryptic peptides were analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF-MS).The mass spectrometric data were used to identify the proteins through searches of the NCBI protein sequence database.Results 37 prominent proteins with various functional characteristics were identified.The identified brain protein classes covered metabolism enzymes,cytoskeleton proteins,heat shock proteins,antioxidant proteins,signalling proteins,proteasome-related proteins,neuron-specific proteins and glial-associated proteins.Furthermore,3 hypothetical proteins,unknown proteins so far only proposed from their nucleic acid structure,were identified.Conclusion This study provides the first unbiased characterization of proteins of the rat hippocampus and will be used for future studies of differential protein expression in rat models of neurological disorders.

ObjectiveTo observe the effect of language rehabilitation on crossed aphasia.MethodsFive right-handed patients with aphasia secondary to acute stroke in the right hemisphere were studied by means of oral fluent of Aphasia Battery of China, the Western Aphasia Battery, grade criterion of the Boston Diagnostic Aphasia and Frenchy Dysarthria Battery. After thirty days language rehabilitation, these cases were studied by the same ways again.ResultsAll five cases were meted with the diagnosis criterion of crossed aphasia, and got a well language function recovery after rehabilitation.ConclusionThere were two types of crossed aphasia:mirror image aphasia and atypical crossed aphasia.Language rehabilitation is effective on crossed aphasia.

OBJECTIVETo study the effects and mechanisms of Huanglian Jiedu Decoction (HJD) and its disassembled recipes containing serums on the proliferation and differentiation of preadipocytes.

METHODSHJD and its disassembled recipes containing serums were prepared. The 3T3-L1 preadipocytes were cultured. The proliferation of 3T3-L1 preadipocytes was detected by methyl thiazolyl tetrazolium (MTT) method. The accumulation of lipid droplets in the cytoplasm of differentiated preadipocytes was observed by oil red O staining and quantitatively analyzed by colorimetry. The mRNA expressions of peroxisome proliferation activated receptor y (PPAR gamma) and CAAT/enhancer binding protein (C/EBP alpha) were detected by reverse transcription polymerase chain reaction (RT-PCR).

RESULTSIntervention with serum containing HJD, Phellodendron amurense Rupr plus Gardenia jasminoides Ellis, or Gardenia jasminoides Ellis showed significantly stimulative effects on the proliferation of preadipocytes, as compared with that in the blank control group (P<0.05, P<0.01). The preadipocytes treated with serum containing HJD, Phellodendron amurense Rupr plus Gardenia jasminoides Ellis, Coptis chinensis Franch or Gardenia jasminoides Ellis showed that the lipid droplets in the cytoplasm were significantly lessened, so did the mRNA expressions of PPAR gamma and C/EBP alpha when compared with the blank control group (P<0.05, P<0.01).

CONCLUSIONSHJD promoted the proliferation of preadipocytes, decreased the accumulation of lipid droplets during the differentiation of adipocytes, and inhibited the differentiation of adipocytes, which might be associated with its effects on decreasing the mRNA expressions of PPAR gamma and C/EBP alpha. Phellodendron amurense Rupr and Gardenia jasminoides Ellis were the main components of HJD playing these roles.

OBJECTIVETo evaluate the curative effect and surigical skills of reconstruction intramedullary nailing in the treatment of ipsilateral femoral neck and shaft fractures.

METHODSFrom January 2007 to January 2013, 13 patients with ipsilateral femoral neck and shaft fractures were treated by reconstruction intramedullary nailing including 11 males and 2 females with an average age of 38.9 yeas old ranging from 25 to 53 years old. For femoral neck fractures,10 cases were basilar neck fracture, 3 were transcervical fractures and according to Garden classification,10 were type II, 2 were type III and 1 was type IV. For feormal shaft fracture, 5 were type I, 4 were type II, 3 were type III and 1 was type IV according to Winquist classification. The location of all 13 feormal shaft fractures were all in the uper 3/4 of the feormal shaft. Complications and postoperative function were recorded and evaluated.

RESULTSEleven patients were followed up for 23.45 months (12 to 36 months). Time from injury to operation was 5.9 days in average. Malunion of femoral neck fracture happened in 1 patient, nonunion of femoral shaft fracture happened in 2 patients. NO femoral head osteonecrosis, infection and malunion of femoral shaft fracture happened. According to Friedman-Wyman classification, 8 cases get good result, 2 get faii and 1 get poor.

CONCLUSIONReconstruction intramedullary nailing is a good choice for the ipsilateral femoral neck and shaft fractures with the advantages of less soft-tissue trauma and complications.
