Objective To evaluate the hematologic effects of linezolid in advanced aged patients with hospital onset of infection.Methods The clinical characteristics and complete blood routine examination results of 45 elderly patients aged(92.9±5.2)years treated with linezolid over 600 mg of lowest dose everyday for more than 72 hours were retrospectively analyzed.Results Among the 45patients,20 patients(44.4%)had substantially lower platelet,6 patients(13.3%)lower haemoglobin,1 patient(2.2%)lower absolute neutrophil,and the linezolid treatment in 19 patients were discontinued due to hematological system adverse reactions.The significant drop in platelet occurred at(10.2±3.3)days after treatment.The significant drop in hemoglobin occurred at(9.8±3.0)d after treatment.The lowest count of platelet and hemoglobin took place at(13.1±3.9)d and (10.5±3.5)d after treatment,respectively.The drops in platelet and hemoglobin of some patients took place after cease of treatment.Stepwise logistic regression analysis revealed that treatment duration(OR =1.407,P<0.05)and creatinine clearance rate(OR=0.732,P<0.05)were the risk factors for thrombocytopenia.Conclusions The elderly patients using linezolid more likely suffer from adverse reactions of hematological system,particularly thrombocytopeniawhich is significantly more common in patients with renal insufficiency and prolongation of treatment time.The blood routine examination should be monitored closely when elderly patients are treated with linezolid.

Objective To evaluate the efficacy and safety of long-term nebulized corticosteroids and inhaled bronchodilators therapy on asthma in long term poor controlled elderly patients.Methods Prospective,randomized control study was conducted.63 elderly asthma patients,who received inhaled corticosteroids or combined with other long-term medication treatment for asthma control for more than 3 months but were still in moderate to severe persistent asthma state,were randomly divided into nebulizer treatment group (n=31) and dry powder inhalation group (n=32),and they were treated correspondingly with Budesonide inhalation suspension 1 mg and Salbutamol 2.5 mg BidorBudesonide/Formoterol powder 320/9 μg inhalation Bid.Patients in the two groups were evaluated for the differences in lung function,acute exacerbations of asthma,asthma control test (ACT) and adverse effects after 12-week treatment.Results The improvement in morning peak expiratory flow (PEF) and ACT score were better in the test group than in the control group [(29.2 ±14.4) ml vs.(15.8±13.5)ml,(4.8±2.2) vs.(3.0±2.7),t=3.715 and 2.897,P=0.000 and 0.005],but there were no statistical differences in average daily use of relievers and severe acute exacerbations between the test and control groups (t=1.512,P=0.136;x2=2.238,P=0.135).The local adverse effects caused by inhaled corticosteroids had no significant difference between the two groups.Conclusions Compared with the powder inhalation,the nebulizer inhalation administration of corticosteroids and bronchodilators could improve the asthma symptoms and lung function better in elderly patients with serious asthma condition and shows a good safety in tbe12 weeks of continuous treatment.

Objective To study the inhibitory effects of stachyose on the hyperacute rejection in pig-to-human heart xenotransplantation.Methods A pig-to-human xenogeneic heart transplantation model was established based on an in vitro free heart blood perfusion system.The pig hearts were di- vided into two groups:group A(pig hearts treated with human blood perfusion as control)and group B(pig hearts treated with human blood plus stachyose perfusion).After perfusion for 1h,the heart xenografts were examined for deposit of lgG and IgM by immunohistochemistry and pathological analy sis.Results The mean survival time of perfusion hearts in groups A and B was(9.5?2.5)min and (46.8?8.1)min respectively(P

Objective To evaluate the effect of single CVVH and HDF on endothelial system. Methods Group CVVH:20 patients with multiple organ dysfunction syndrome ( MODS) underwent CVVH for 12h.Vascular access was through two-lumen catheter in femoral vein;Group HDF:Twenty patients with end stage renal disease (ESRD) on maintenance hemodialysis underwent HDF for 4h.Vascular access was through internal arteriovenous fistula.Group control:Healthy people were examined at our hospital.The se-rum levels of sVCAM-1, sICAM-1, vWF and MMP-9 were measured by enzyme-linked immunosorbent assay ( ELISA) after centrifugation in treatment group before and after treatment.Four cytokines were also meas-ured in fasting healthy subjects in the morning.Results The levels of serum sVCAM-1, sICAM-1, vWF, MMP-9 were significantly higher in Group CVVH and HDF than control group before and after treatment( P<0.05).Group CVVH:The serum levels of sICAM-1 and sVCAM-1 were significantly lower in post-treat-ment than pre-treatment, But the serum levels of vWF and MMP-9 showed no obvious changes after CVVH;Group HDF:the levels of four cytokines showed no obvious changes after single HDF.Conclusions Endo-thelium becomes impaired in MODS and ESRD patients, Endothelium may be protected by CVVH through the partial removal of cytokines harmful to endothelium in MODS patients.Single HDF therapy does not pro-tect endothelial function obviously in MHD patients.

To establish a convenient and rapid method for identification of Pseudostellariae Radix by molecular identification, the rDNA-ITS sequences of Pseudostella riaheterophylla and its adulterants had been aligned to find out specific fragment. The specific primers against the fragment were designed and the PCR amplification conditions were optimized. The fluorescence reaction of the PCR products colored by 100 x SYBR Green I was observed under UV. The concentration of reaction buffer included 5.5 μL DNA Taq polymerase premix, 10 pmol Tzs-2F and 10 pmol Tzs-2R, 20-80 ng template DNA, and plus double sterile distilled water to 25 μL. The PCR thermal profile was as follows: predenaturation at 95 degrees C for 1 min, followed by 30 cycles of denaturation at 95 degrees C for 5 seconds, primer annealing and extension at 56 degrees C for 15 seconds, then it was extension at 72 degrees C for 30 seconds. The fluorescence reaction of Pseudostellariae Radix showed green fluorescence, while adulterants had not. Extraction, amplification DNA and all steps of molecular identification could be completed successfully in 40 minutes. The approach could amplify DNA template of Pseudostellariae Radix specificity, and its product with 1 μL 100 x SYBR Green I could engender green fluorescence under UV. The method was simple and accurate, so it could be used for identification of Chinese traditional medicine.

BACKGROUND: Educative instruction is good for the improvement of learning and behavior disorder in children with learning disorder. If this educative instruction were individualized, i. e. different education is provided for different individual, it would receive even better effects.OBJECTIVE: To explore the method and effect of educative instruction for children with learning disorder to accumulate experiences for the development of their learning potentials.DESIGN: A paired(pairing the subjects with similar age and learning disorder) case analysis based on the suffers .SETTING: A medical college of some university.PARTICIPANTS: Eight children with learning disorder were selected from Zhenjiang City Dongwu Kindergarten or Zhenjiang City Dagang Central Primary School. These 8 cases suffered from 4 types of disorders including clumsiness, seclusive personality, language disorder, and poor learning ability. Eight cases were randomly divided into education group and control group.METHODS: Cases of control group received normal educations without specific interventions. Cases of education group received individual customized educative instructions. The educative effects were observed after 3 months.MAIN OUTCOME MEASURES: The improvement of clumsiness, seclusive personality, language disorder or poor learning ability in children with learning disorder.RESULTS: Cases of education group had better psychological and behavior improvements than that of control group after individual educative instruction.CONCLUSION: Individual educative instruction for children with learning disorder is an effective approach for the development of their learning potentials.
