Objective To explore the effect of prospective nursing on preventing constipation for patients with acute myocardial infarction(AMI). Methods 43 AMI patients during July 2008 and June 2010 in our hospital were classified as the observation group, besides the nursing routine of the acute myocardial infarction plus routine therapy to prevent constipation, prospective nursing was implemented.Through the retrospective analysis of medical record, 41 of AMI in our hospital during March 2006 and June 2008 were classified as the control group, they were given the nursing routine of the acute myocardial infarction plus routine therapy to prevent constipation and the nursing intervention after occurrence of constipation. The defecation condition was assessed for the two groups of patients on admission and the defecation and mortality rate was compared on the eighth day of hospitalization. Results There was significant difference in constipation and mortality rate between the two groups of patients during hospitalization. Conclusions The prospective nursing for AMI patients to prevent constipation can obviously reduce the incidence of constipation, thus to avoid serious complications caused by constipation and reduce mortality.

OBJECTIVE To investigate the relationship between phenotypes and genotypes of clinical isolates of ESBLs-producing Klebsiella pneumoniae.METHODS Agar dilution method was used to test the MICs of 11 antibiotics against 67 ESBLs-producing K.pneumoniae strains.PCR was performed for amplifying ?-lactamase-encoding genes of SHV-,TEM-,and CTX-M-type,and the PCR products of some strains were cloned and sequenced to identify their gene serotypes.RESULTS With no imipenem-resistant strains among 67 strains,their resistant rates to 10 kinds of antibiotics were 10.45-89.55% The cross-resistant rates to aminoglycosides of 60 strains and to ?-lactams of 44 strains were 88.33% and 40.91%,respectively.The positive rates of SHV-,TEM-,and CTX-M-type for 67 strains were 91.04%,56.72% and 28.36%,respectively,and SHV-12,TEM-1 and CTX-M-3 genotypes were found in 7 strains by cloning and sequencing.CONCLUSIONS Sixty seven strains of ESBLs-producing K.pneumoniae present a clear feature of multi-resistance and cross-resistance to most of antibiotics except imipenem,among them there are 7 strains producing SHV-12 and CTX-M-3 extended-spectrum ?-lactamase coexistent with TEM-1 broad-spectrum ?-lactamase.

Objective To establish a method for rapid preparation of antiserum against influenza virus (H7N9) hemagglutinin,and to study the possibility of using it in single radial immunodiffusion (SRID) assay for quantitative detection of antigen in H7N9 influenza vaccine.Methods Hemagglutinin proteins expressed in eukaryotic cells were used to immunize sheep.Serum samples were collected to detect antibody titers by ELISA and double immunodiffusion assay.Different concentrations of antiserum were used in SRID assay to get the optimized concentration.Results After 4 times of immunization,the antiserum titers achieved 1 ∶ 1 000 000 and 1 ∶ 32 as indicated by ELISA and double immunodiffusion assay,respectively.The antiserum could form a clear precipitation line in SRID assay.The detection of antigen in the range of 10 to 40 μg/ml showed good linearity in the standard curve.The antigen titers in six batches of H7N9 vaccine detected by this SRID assay were identical with those by SDS-PAGE assay.Conclusion The antiserum against H7N9 hemagglutinin for SRID assay was developed successfully,and could be used as a reagent for the quantitative detection of antigen in H7N9 influenza vaccine.

ObjectiveTo study the anatomical abnormalities of basal ganglia and research their influence on depression status in patients with post stroke depression (PSD)by diffusion tensor imaging (DTI) of MRI.MethodsPatients with basal ganglia infarction were recruited,and divided into groups of PSD and non depression control group by Hamilton Depression Rating Scale (HAMD) assessment. All the patients were evaluated with National Institute of Health Stroke Scale ( NIHSS). And the patients were checked by DTI sequence.Fractional anisotropy (FA),average diffusion coefficient (ADC) values and the number of nerve fiber were measured in bilateral caudatum,pallidum,putamen and thalamus.ResultsThe score of NIHSS (6.29 ± 3.45 ) was significantly higher in PSD group than that in non-depression group (3.95 ± 1.90 ;t =2.219,P =0.036). No significant difference was found between the two groups for the DTI data of the basal ganglia nuclei ( t =0.056-1.618,all P > 0.05 ). Compared with contralateral construction (0.40 ± 0.02 ),the FA value decreased in the left putamen ( 0.37 ± 0.03 ) in the PSD group ( t =2.243,P =0.045 ).By Spearman correlations analysis,the HAMD score was positively correlated with NIHSS score ( r =0.464,P =0.017 ),and negatively correlated with the FA values of left pallidum (r=-0.563,P=0.005),right pallidum (r=-0.416,P=0.035) and left putamen (r =-0.428,P =0.029).Conclusions The occurrence of PSD was associated with neurological functional deficit following basal ganglia infarction.The depression level was correlated with the increasing of NIHSS score,the reductions in bilateral pallidum and left putamen FA values.This research contributes to evaluation of the PSD status in patients with basal ganglia infarction.

Objective To evaluate the effect of greater trochanteric transfer for the treatment of coxa brevis in children and adolescents.Methods From August 2005 to January 2011,twenty patients (22 hips)with coxa brevis underwent greater trochanteric transfer.Among them 18 patients (20 hips) were available for evaluation,including 4 boys and 14 girls,with an average age of 11.4 years (range,7.5-15.0 years) at operation.Five cases (6 hips) were caused by Perthes disease,and 13 cases (14 hips) were caused by developmental dysplasia of hip.Four patients (4 hips) had undergone greater trochanteric epiphyseodesis ever before.All patients were fixed with tension screw after the deformity was corrected during the operation.After operation,the human plaster spica was used for 6 weeks in all patients.Results All patients were followed up for 14 to 79 months (average,31 months).At the last follow-up,fatigue or pain in the hips disappeared or improved in 13 patients.Sixteen patients had limping and positive Trendelenburg sign preoperatively,at the last follow-up 9 patients got improvement.Twelve patients (13 hips) had limitation of abduction of the hip,the average range of abduction was 25.38°±1.20°,which was improved to 45.38°±1.05° at the last follow-up.The average articulotrochanteric distance and ratio of the distance from the greater trochanter tip to femoral head center and the radius of the femoral head at the last follow-up was (17.47+3.14)mm and 2.10±0.21,respectively,there were statistical differences compared with those before operation [(-2.89±4.62) mm and 1.59±0.22,respectiovely].The average leg-length discrepancy at the last follow-up was (0.78t±0.26) cm,which had on statistical differences compared with that [(0.83 ±0.33) cm]before operation.Conclusion Greater trochanteric transfer for the treatment of coxa brevis in children and adolescents could improve the clinical symptom,recover the normal anatomy of the proximal femoral,restore the hip biomechanics environment,but could uot improve the leg-length discrepancy.

In plants, proteins with A20/AN1 zinc finger domain are involved in stress responses, named as "Stress Associated Protein" (SAP) gene family. Based on Expressed Sequence Tag (EST) sequences information in Badila Saccharum officinarum mature related cDNA library, we cloned an SAP gene from sugarcane full length cDNA library, named ShSAP1 (GenBank: Accession No. HM991960). To characterize ShSAP1, we analyzed its genome structure and expression pattern. Southern blot analysis showed ShSAP1 was present as one or two copy in the genome of Badila. Comparison of ShSAP1 1 008 bp full length cDNA with a genomic frangment (2 241 bp) generated by PCR amplification and sequencing, revealed the presence of two introns (202 bp and 1 052 bp) located in the 5'UTR region. Semiquantitative RT-PCR analysis found ShSAP1 expressed in leaves, roots and stalk in mature sugarcane. Compared with immature stems, ShSAP1 expressed higher in mature stalk. ShSAP1 was induced by different types of treatments, such as salt (200 mmol/L NaCl), drought (10% PEG 6 000), GA3 (200 mg/L), ABA (100 micromol/L) and ET (1 mmol/L) during sugarcane seedling stage. These results indicated that ShSAP1 may function in sugarcane maturation and abiotic stress response processes.
