Chinese Journal of Rehabilitation Theory and Practice 2011;17(4):372-374
ObjectiveTo investigate the influential factors on the deaf children's hearing and speech rehabilitation.Methods43 deaf children were involved in our study. They performed the hearing thresholds, hearing ability, speech ability and learning aptitude tests.ResultsGender and hearing aid mode didn't correlate with the children's hearing and speech performance (P>0.05). Hearing thresholds had significant influence on the hearing ability (P<0.05), and the speech ability had a strong correlation with the children's learning aptitude (P<0.05). The multiple regression analysis showed that the hearing ability was a significant predictor of speech ability (P<0.001).ConclusionGiving hearing compensation timely and effectively and grasping the critical period of language development to do rehabilitation training as soon as possible are very important to deaf children's rehabilitation of hearing and speech ability.
2. Regulatory role of phosphatidylinositol 4,5-bisphosphate in transient receptor potential channel
Academic Journal of Second Military Medical University 2010;31(8):887-891
Transient receptor potential(TRP) superfamily includes seven subfamilies and TRP channels are regulated by a wide variety of physical and chemical factors. Recently, several members of the TRP channel family have been reported to be regulated by phosphatidylinositol 4,5-bisphosphate(PIP2). The regulation is complex and it can be activation or inhibition, involving multiple mechanisms and factors. This review summarizes the PIP2 regulation of several TRP channels of different superfamilies and the related pathophysiological significance.

Objective To investigate the distribution and susceptibility of carbapenem resistant citrobacter freundii for rational antimicrobial therapy.Methods The C.freumdii were collected between January 2011 and December 2014 from inpatients.The minimum inhibitory concentration (MIC) were detected by an automated analyzer (VITEK 2) to analyze the characteristic of tested bacteria.Results (1) Of the 21 strains of carbapenemresistant citrobacter freundii,95% were collected from urine,among which most of the strains were isolated from the Department of Transplantology (66.7%) and Urology (19%);(2) Antimicrobials Susceptibility test showed that Citmbacter freund were highly resistant to Cephalosporins and relevant beta-lactamase inhibitors.Even carbapenem were highly resistant.Imipenem had a resistance rate of 90% (95% confidence interval:70 to 99),Meropenem 85.7% (95% confidence interval:64 to 97),The drug resistance rate to Amikacin was only 4.8%,followed by Nitrofuran toin (10.5%) and Fosfomycin (15%).Conclusions Carbapenem resistant citrobacter freundii,which often causes urinary tract infection in our hospital,was characterized by multi-drug resistant (MDR).Monitoring of the Citrobaeter freundii should be strengthened to control the prevalence of drug resistance.

Objective: To study the anti-inflammatory, analgesic and immunosuppressive action of Niuhuang Qianjin San (NQS). Methods: The anti-inflammatory action of NQS was studied by the methods of rat paw swelling and mouse ear swelling and the analgesic action by mouse body torsion method and K + subcutaneous penetration method in rats.Immunosuppressive effect was evaluated by peripheral T lymphocyte percentage, splenic lymphocyte transformation ratio, phagocytic function of intraperitoneal magocytes, the activity of delayed hypersensitivity, serum hemolysin level and the function of antibody-yielding cells in mice. Results: NQS could obviously alleviate inflammation, increase codeine's analgesic action and suppress immunity. The difference were significant (P

7. Brain-targeted nasal drug delivery systems for the treatment of neurodegenerative diseases
Journal of International Pharmaceutical Research 2016;43(1):104-109
Incidence of neurodegenerative diseases has been increasing year by year in the current aging society which interferes the living quality of the patients severely. Pathological changes in neurodegenerative diseases appeare in central nervous system CNS . The administration route of drugs to treat neurodegenerative diseases becomes a very important scientific research field. Part of drugs may cross over blood-brain barrier BBB to CNS by oral or injection administration. But most of drugs are distributed in the other tissues and might cause adverse reactions, such as gastrointestinal side-effects and arrhythmia. Moreover, the compliance of the aging patients is poor. They cannot adhere to administer multi-dose drugs for sereral times a day. Nasal drug delivery systems could deliver drugs to brains directly by nasal-brain route, avoiding BBB with high targeting ratio, high drug availability and good patients’ compliance. The review summarizes the major types of neurodegenerative diseases and their current therapeutic methods. The important obstacles for brain-targeted drug delivery, nose-brain routes and the factors influencing nasal absorption are introduced. More importantly, the principal formulations, recent research progress and the unsolved problems of brain-targeted nasal drug delivery systems are also reviewed.
8. In vitro pharmacodynamic evaluation of anti-HIV cholesteryl-phosphoryl zidovudine self-assemblies
Journal of International Pharmaceutical Research 2013;40(1):69-72
Objective To evaluate the anti-HIV activity of the self-assemblies of cholesteryl-phosphoryl zidovudine (CPZ) and provide evidence for the promising new anti-HIV drug. Methods CPZ self-assemblies were prepared. The MT4 cells infected by HIV-1 were the model to evaluate the anti-HIV activity of CPZ self-assemblies, which based on the generation of combined ceHs, was compared to that of the parent drug-zidovudine (AZT). The cytotoxicity of CPZ self-assemblies as evaluated by the MTT method. Phagocytosis of macrophage to CPZ self-assemblies was evaluated in RAW264. 7 ceHs. Results The anti-HIV activity of CPZ self-assemblies was much higher than that of AZT, with the half effective concentration (EC50) 1/10 to 1/50 that of AZT. The selectivity index (SI) was high, indicating that the self-assemblies were safe. Conclusion CPZ self-assemblies have high anti-HIV activity and is apromisinganti-HIV drug.

Objective To explore the clinical effect of innovative bladder irrigation on prevention of urinary tract infection in neurogenic bladder patients with clean intermittent catheterization after spinal cord injury (SCI). Methods 40 neurogenic bladder patients with clean intermittent catheterization after SCI were divided into observation group (n=20) and control group (n=20). The observation group received innovative bladder irrigation with normal saline 500 ml every other day, and the control group received normal bladder irrigation with normal saline 500 ml every day. Results 4 weeks and 6 weeks after treatment, the incidence of urinary tract infection was lower in the observation group than in the control group (P<0.05). Conclusion The innovative bladder irrigation method can decrease the rate of urinary tract infection in neurogenic bladder patients with clean intermittent catheterization after SCI.

Objective To explore the reliability and validity of Meadow-Kendall Social-Emotional Assessment Inventory (SEAI) for Deaf and Hearing-Impaired Students Preschool Version in China. Methods 96 hearing-impaired children were assessed with SEAI, and 30 of them were assessed with Conners Teacher Rating Scale (TRS), 30 by another teacher, 30 by the first teacher 2 weeks later. The data were analyzed with Pearson's or Spearman's correlation analysis. Results For sociable communicative behaviors, impulsive dominating behaviors, developmental lags, anxious compulsive behaviors, items related to deafness, test-retest reliability (correlated coefficient, r) was 0.94,0.55, 0.87, 0.31, 0.74; and Cronbach's α was 0.70, 0.76, 0.76, 0.80, 0.68. The inter-rater reliability was 0.90, 0.58, 0.46, 0.14, 0.55. The subscales of SEAI were correlated (r=-0.36~-0.89, P<0.05) with the subscales of TRS. Confirmatory factor analysis showed that the subscale model of SEAI was reasonable. Conclusion The SEAI for Deaf and Hearing-impaired Students Preschool Version can be used for Chinese hearing-impaired children.
