Objective In order to assist the medical staff to take appropriate contents and ways of health education,and to promote the recovery of physical and mental health of children with attention deficit hyperactivity disorder (ADHD),the needs of the parents about how to help them acquire the related knowledge were investigated.Methods A survey on the degree of familiarity of nursing knowledge,the requirements and the ways for getting the knowledge about the health education was carried out.Results The rate of 226 parents who knew about nursing knowledge was 10.62％-87.61％ (24/226-198/226).More than half of the parents needed health education.The rates of concerns were as follows,92.48％ (209/226) of all the parents concerned on the factors affecting prognosis,94.69％(214/226) on the comorbidities,92.04％ (208/226) on the training methods of attention,and 91.15％ (206/226) on psychological and behavioral interventions.Conclusions Parents could acquire related knowledge and educational methods about ADHD from the medical staff and afford a good care,which may improve behavior problems and mental health of the children with ADHD.

Objective To establish a reversed HPLC method to determine the contents of gatifloxacin and tinidazole simultaneously. Methods ODS C_ 18 column (4.6mm?250mm,5?m) was used as an analytical column. The mobile phase consisted of 15% acetonitrile, 25% of methanol and 60% of 0.05mol/L KH_2PO_4 buffer,which contained 0.5% triethylamine and was adjusted to pH 3.5 by phosphoric acid. The flow rate was 1ml/min. The detection wavelength was 318nm. The column temperature was 30℃. 20?l of diluted sample solution was injected to the sampler. Results The calibration curve of gatifloxacin was linear in the range of 2~20?g /ml (r=0.999 6) ,and that of tinidazole was 2~20 ?g /ml (r=0.999 9). The recovery rates of them were 100.1% and 100.4%,respectively. RSDs of both drugs were less than 1.1 %. Conclusions The method is simple,accurate and sensitive and can be used to determine the two components simultaneously.

Bone marrow-derived stem cells, mainly including hematopoietic stem cells, mesenchymal stem cells, multipotent adult progenitor cells, etc., are the most densely studied adult stem cells up to now. Recent findings indicate that adult stem cells have the potential to differentiate across lineage barriers and to adopt the expression profiles and functional phenotypes of cells unique to other tissues. This flexibility is termed "plasticity",which has posed challenges to conventional concepts. Meanwhile, it brings new hopes for the therapeutic application of cell engineering and tissue engineering. This review focuses on the biological features, the plasticity and its possible mechanisms, research method and potential clinical application of bone marrow-derived adult stem cells

Objective To explore the prevalence of qnr gene in gram-negative bacteria isolated from Renmin Hospital of Wuhan University. Methods qnr gene was detected by PCR in non-duplicate E.coli (n=129), E.cloacae (n=10) and K.pneumoniae (n=29) isolates.PCR technique was used to amplify the gene encoding type I integrons.Kirby-Bauer disk diffusion method was used to test the in vitro suscepti- bility of the isolates to 16 antimicrobial agents.ESBLs were investigated according to phenotypie screening and confirmatory test recom- mended by NCCLS.MIC values of ciprofloxacin were determined for qnr gene positive strains.Results qnr gene were identified in 6 clinical isolates including 5 strains of E.coli and I E.cloacae, qnr gene was not found in K.pneumoniae isolates.The 6 qnr-positive clinical iso- lates were positive for type I integrons.All the 6 strains were susceptible to imipenem but resistant to many other drugs tested.Only 2 of the E.coli isolates were susceptible to ciprofloxacin.Conclusions In Hubei Province, the prevalence of qnr is confirmed.The serious situa- tion of multidrug-resistance in clinical isolates with qnr gene requires careful monitoring of qnr-carrying isolates.

Objective:To investigate the corrosion fatigue strength of laser-welded specimens fabricated from commercially pure titanium (TA2) and titanium alloy(TC4). Methods:TA2 and TC4 were mechanically processed into a certain size and joined by laser welding. A fatigue testing machine was used to test tensile load and fatigue strength after soaked in synthetic saliva. The fatigue fracture surface was examined by scanning electron microscopy (SEM). Results: The fatigue strengths of the laser-welded test specimens showed no significant differences compared to specimens in air. SEM examination showed that there were no defects such as corrosion pits. Conclusion: There are no significant differences between either laser-welded metal in the corrosion fatigue strength for dry specimens and specimens in synthetic saliva.

0.05).The activities degrees of ankle joint also had no statistical difference.[Conclusion]According to the extent of the displacement of Cotton's fracture,we should make the right operative order and the incision,thus we can get results with anatomic reduction and shorten the operative time,which can help the patients make early exercises and get satisfactory effect.

ObjectiveTo investigate whether miR-25 targets KLF4 to regulate the growth of gastric cancer cells and lucidate the mechanism of miR-25 producing functional effects in gastric cancer cells. Methods The expression levels of miR-25 and KLF4 were detected by qRT-PCR in 35 pairs of gastric cancer tissues of patients. Target genes of miR-25 were predicted using Targetscan and verified though dual luciferase activity assay and west-ern blot. MTT assay and clone formation assay were detected after downregulated miR-25 and overexpressed KLF4 respectively. Results miR-25 was highly expressed in gastric cancer tissues with KLF4 downexpresstion. Downreg-ulated miR-25 and overexpressed KLF4 respectively can significantly reduce the proliferation of gastric cancer cells,the results were opposite when overexpression of KLF4. Conclusion miR-25 promotes gastric cancer cells proliferation by targeting KLF4.
