OBJECTIVE To investigate the distribution and the resistance variance tendency of the pathogenic bacteria isolated from the blood cultureing specimens collected during the period of 2002-2005.METHODS A retrospective analysis was made to the blood cultureing results during the period of 2002-2005 with WHONET 5.1 software.RESULTS Gram-negative rods were the predominant bacteria which caused sepsicemia,the isolated rates of Escherichia coli,Klebsiella pneumoniae and Staphylococcus aureus were the most high during the period of 2002-2004 but the S.epidermidis and S.hominis were also the important pathogenic ones which caused blood stream infection.Vancomycin and the teicoplanin were the most effective to the Gram-positive bacteria,and the imipenem and the cefepime were the most effective to the Gram-negative ones.CONCLUSIONS It′s important to strengthen the blood cultureing for blood stream infection patient.

Objective To investigate the effects of rehabilitation nursing on quality of life in patients after burn injuries. Methods The re-ports about rehabilitation nursing for burn patients from January, 2004 to June, 2015 were searched and extracted from the databases of Chi-na Biology Medicine, China National Knowledge Infrastructure, Wangfang Data and Chongqing VIP Database, and analyzed with Review Manager 5.3. Results 11 non-randomized control studies (MINROS score:13~19) were eligible for meta-analysis. There were significant differences in the general health (MD=7.78, 95%CI:6.79~8.77, P<0.001), social function (MD=10.26, 95%CI:5.91~14.60, P<0.001), men-tal function (MD=9.71, 95%CI:6.87~12.55, P<0.001) and physical function (MD=6.88, 95%CI:3.95~9.81, P<0.001) between experimental group and control group. Conclusion Rehabilitation nursing can improve the quality of life of burn patients.

Syndrome of resistance to thyroid hormone(RTH)is a rare hereditary thyroid disease with various clinical manifestations and laboratory findings. RTH could be misdiagnosed and mistreated, resulting in aggravation of the disease. We reviewed the medical records of a patient with RTH over the past six years. In addition, we provided a summary of latest progress for RTH to help the clinicians to improve the understanding of the disease.

OBJECTIVETo investigate the differential gene expression profile from patients with Bardet-Biedl syndrome (BBS) by oligonucleotide microarray technique.

METHODSTotal RNA of 3 probands with BBS and 4 healthy siblings were isolated from peripheral blood mononuclear cells and reverse-transcribed to cDNAs. Then the cDNAs were subjected for microarray screening with Affymetrix U133 Plus 2.0 array. Genechip scanner was applied to screen the hybridization signals. Genes differentially expressed between the BBS probands and controls were identified by using GCOS1.4 software with the standard of two-fold change (P<0.05) of expression.

RESULTSFifteen genes were up-regulated 2 or more fold and another 15 genes were down-regulated 2 or more fold in the BBS patients, among them 12 genes were related to signaling pathway and cell cycle by Gene Ontology (GO) analysis.

CONCLUSIONThe differentially expressed genes identified may correlate with the function or structure of cilia. Their roles in the BBS genesis need to be further studied.

OBJECTIVE:To study the inhibitory effect and mechanism of Inula helenium ethyl acetate extract(IHE)on prolif-eration of human pancreatic cancer Capan-2 cells. METHODS:MTT was used to determine the cell proliferation inhibition rate af-ter treated by 0,0.5,1,2,4,8 μg/mL IHE;clone formation test was used to observe the effects of 0,1,2 μg/mL IHE treating for 1 week on cell clone formation;Hoechest 33342 staining was used to observe the changes of nuclear morphology after treated by 0,2,4 μg/mL IHE for 48 h;flow cytometry was used to detect the cell apoptosis rate after treated by 0,4,8,16 μg/mL IHE for 48 h;JC-1 staining was used to observe the changes of intracellular mitochondrial membrane potential after treated by 0,4,8, 16 μg/mL IHE for 24 h;Western blot was used to detect the expressions of mitochondrial apoptosis-related proteins Bcl-2,Bax, Mcl-1,p53 up-regulated modulator of apoptosis (PUMA),and polymerase (PARP) after treated by 0,4,8,16 μg/mL IHE for 48 h. RESULTS:2,4,8 μg/mL IHE had obvious inhibitory effect on cell proliferation,showing concentration-dependent relation-ship,with IC50 of 6.6 μg/mL;1,2 μg/mL IHE can obviously inhibit the clone formation of cells;4 μg/mL IHE can obviously cause cell nuclear condensation;8,16 μg/mL IHE can obviously promote the cell apoptosis,and the cell apoptosis rate reached 45.53% after treated by 16 μg/mL IHE for 48 h;16 μg/mL IHE treating for 24 h can cause the decrease of 82.47% cells'mito-chondrial membrane potential;8 μg/mL IHE can obviously down-regulate the protein expressions of Bcl-2,Mcl-1,PUMA and PARP,and 16 μg/mL IHE can obviously down-regulate the expressions of Mcl-1 and PUMA. CONCLUSIONS:IHE may show its inhibitory effect on proliferation of human pancreatic cancer Capan-2 cells by causing the decrease of mitochondrial mem-brane potential in cells and down-regulating the protein expres-sions of Mcl-1 and PUMA to cause cell apoptosis.
