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

BACKGROUND: Many animal and clinical studies have reported that the safe and effective usage of umbilical cord blood-derived mesenchymal stem cells (UCB-MSCs) transplantation for treatment of neurological genetic diseases.OBJECTIVE: To investigate the feasibility and effect of UCB-MSCs transplantation in the treatment of spinal muscular atrophy (SMA).METHODS: A child admitted at January 2010 had been confirmed as having SMA, and drug and rehabilitation therapies were invalid. Then, the child received UCB-MSCs transplantation via the first intravenous infusion and three times of subarachnoid injection, once a week, (4-6)×107 cells once and four times as a course. Neurological physical examination, biochemical test, muscle enzymes detection, FIM scoring and electromyography (EMG) examination were conducted. RESULTS AND CONCLUSION: Compared with prior to transplantation, the level of muscle enzymes decreased, FIM scores were increased from 68 to 93 points, EMG results showed that the motor units with re-contraction in each 10.0 ms were increased that the motor function was improved, the lower extremity muscle strength elevated, and the self-care ability was improved in the SMA child at 6 months after transplantation. During the 10-month follow-up, the child had no adverse effects. It is indicated that UCB-MSCs transplantation is effective to treat SMA, and the neurological function has a remarkable restoration.

This study examined the mechanism by which the gastric cancer cells lead to early peritoneal metastasis. HMrSV5 cells, a human peritoneal mesothelial cell line, were co-incubated with the supernatants of gastric cancer cells. Morphological changes of HMrSV5 cells were observed. The cell damage was quantitatively determined by MTT assay. The apoptosis of HMrSV5 cells was observed under transmission electron microscope. Acridine orange/ethidium bromide-stained condensed nuclei was detected by fluorescent microscopy and flow cytometry. The expressions of Bcl-2 and Bax was immunochemically evaluated. The results showed that conspicuous morphological changes of apoptosis were observed in HMrSV5 cells 24 h after treatment with the supernatants of gastric cancer cells. The supernatants could induce apoptosis of HMrSV5 cells in a time-dependent manner. The supernatants could up-regulate the expression of Bax and suppress that of Bcl-2 in HMrSV5 cells. These findings demonstrated that gastric cancer cells can induce the apoptosis of HPMCs through supernatants in the early peritoneal metastasis. The abnormal expressions of Bcl-2 and Bax may contribute to the apoptosis. Anti-apoptosis drugs promise to be adjuvant chemotherapeutic agents in the treatment of peritoneal metastasis of gastric cancer.

Objective To explore the social-emotional competence of hearing-impaired children and its related factors. Methods A questionnaire was used to investigate the social-emotional competence, hearing status, temperament and parenting style of 68 hearing-impaired children. Results and Conclusion The social-emotional problems of hearing-impaired children were prominent, especially in the dimension of externalizing behavior (13.23%) and competence (10.29%). The girls had more implicit behavior problems than the boys (P<0.05). Aided thresholds, children's temperament and parenting style had significant influence on social-emotional competence of hearing-impaired children (P<0.05).

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.
