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.

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.

ObjectiveTo examine the mental health status and its changes among children exposed to the Wenchuan earthquake 2 and 3 years after it has passed,and evaluate the possible influencing factors of mental health.MethodsThe General questionnaire,the self-reported Children's revised impact of event scale(CRIES)and the Depression self-rating scale for children ( DSRSC ) were administered to the same children from the earthquake affected areas 2,3 years after the earthquake.ResultsBoth of the CRIES scores and DSRSC scores had decreased over the 2,3 years periods after the earthquake ( z =- 8.772,P =0.00; z=- 2.870,P =0.00 ).The risk factors associated with PTSD 3 years after the earthquake were:gender (OR =1.069,P =0.00 ),the severity of their family's injury( OR =1.141,P =0.02 ),the length of living in transferred safe places( OR =1.416,P =0.03 ),and whether or not witnessed collapse ( OR =1.014,P =0.01 ).The risk factors associated with depression 3 years after the earthquake were:gender( OR =1.367,P =0.00),age( OR =1.035,P =0.04),and despair( OR =2.490,P =0.01 ).ConclusionBoth of the symptoms of PTSD and depression among the children from earthquake affected areas have decreased over the 2,3 years periods after the earthquake.The mental health status of the children from the earthquake affected areas are influenced by their gender,age,the length of living in transferred safe places,the severity of their family's injury,whether or not witnessed collapse and despair.These factors should be taken into considerations when the long-term post-traumatic psychological interventions are planned.

Objective To evaluate the diagnostic value of thyroid microcarcinoma using contrastenhanced ultrasound(CEUS).Methods The CEUS characteristics of 31 lesions in patients with thyroid microcarcinoma which were confirmed by surgery and pathology were retrospectively analyzed.[Results]The enhancement features of 31 lesions were hypoenhancement,morphological irregularity,and lack of a complete envelope.The time intensity curve showed late washed in and late washed out.The start-time of the lesions was later than that of normal thyroid tissue.The enhancement intensities of the lesions were lower than that of normal thyroid tissue.Conclusions The contrast enhancement patternshypoenhancement,suggested that the CEUS might provide a useful,quantitative analysis method for the diagnosis of thyroid microcarcinoma,which can improve diagnostic confidence in thyroid microcarcinoma.

BACKGROUND: Bone marrow mesenchymal stem cells are characterized by wide sources and low immunogenicity. Especially, these cells are easy to import and express foreign genes, and thus have obvious superiorities as anti-tumor gene therapy vectors. OBJECTIVE: To investigate the effects of interleukin-12 gene modified bone marrow mesenchymal stem cells on the proliferation, cell cycle and apoptosis of ovarian cancer cells. METHODS: Interleukin-12 recombinant adenovirus vector was used to transfect bone marrow mesenchymal stem cells. Then, the expression of interleukin-12 mRNA and protien in transfected bone marrow mesenchymal stem cells was detected by RT-PCR and western blot assay, respectively. The level of interleukin-12 in cell supernatant was determined by ELISA. The SKOV3 cells were co-cultured with the supernatant of bone marrow mesenchymal stem cells transfected with (transfection group) or without (control group) interleukin-12 recombinant adenovirus vector. The proliferation of SKOV3 cells was determined by MTT assay. Flow cytometry was used to detect the cell cycle and apoptosis of SKOV3 cells. RESULTS AND CONCLUSION: RT-PCR and western blot results showed that interleukin-12 mRNA and protein were expressed in transfected bone marrow mesenchymal stem cells, but not found in empty vector group and blank control group. ELISA results showed that the content of interleukin-12 in the supernatant of bone marrow mesenchymal stem cells was (68.78±12.35) μg/L in the interleukin-12 transfection group after 48 hours culture, and no interleukin-12 expression was detected in the empty vector group and the blank control group, Interleukin-12-transfected bone marrow mesenchymal stem cells significantly inhibited the proliferation of SKOV3 cells, and the proliferation inhibition rate was increased with time (P < 0.05). The proportion of G1-phased SKOV3 cells was higher in the transfection group than in the control group (P < 0.05), and the percentage of G2-phased SKOV3 cells was lower in the transfection group than in the control group (P < 0.05). The apoptosis rate of SKOV3 cells in the transfection group was higher than that in the control group (P < 0.05). Our experimental findings indicate that bone marrow mesenchymal stem cells transfected with interleukin-12 recombinant adenovirus vector can express interleukin-12, inhibit the proliferation and induce apoptosis of ovarian cancer cells.
