Objective To investigate the perception of communication difficulties of children with hearing impairment and their parents.Methods Using the abbreviated profile of hearing aid benefit (APHAB),perception of communication difficulty in daily situations of the children with hearing impairment and their parents was measured,then the scores were compaired.Results There was no significant difference in perception of communication difficulty between the children and their parents.On problems on ease of communication(EC) and aversiveness(AV), there was difference in the perception of communication difficulty between the children who did not wear hearing aids and their parents.Conclusion It's critical to teach the parents knowledge about hearing loss to reduce their communication difficuty.

Objective To investigate and compare the perception of communication difficulties by mainstreaming students with hearing impairment and that of their peers.Methods The children’s version of the Abbreviated Profile of Hearing Aid Benefit (APHAB) was used to measure perceived communication difficulty in various daily situations.Results There was significant difference between the perception of mainstreaming students and that of their peers for the background noise(BN) subscale questions.Conclusion In order to improve the communication ability of the students with hearing impairment, it is critical to educate one of their important communication partners—their peers, about the hearing loss and its effect on communication, especially under the situation of background noise.

Objective To design a private cloud storage system to guarantee intranet and internet data security and realize data sharing between multi platforms.Methods The idea and solution for building the system were proposed by analyzing the difficulty during hospital informatization.The infrastructure based on the idle computing resources in the existing virtual pool and the application platform by private cloud storage software were involved in the development of the system,and related software and hardware were integrated after adjustment and customization,and then the system came into being with easy operation and high performance-cost ratio.Results The system developed realized freely data storage and sharing,and implemented file encryption to control the applied range.Conclusion The system has the functions of malicious code scanning,cooperative office system and data auto-backup,synchronization,transmission,sharing and etc,which executes intranet and intemet data sharing based on physical isolation.

The paper uses computer multimedia technology to collect and switch audio and video signals, constructs the remote High Definition ( HD) surgery demonstration system which supports live broadcast, recorded broadcast, rebroadcast and video-on-demand depending on the network communication routing technology.It introduces functions, design scheme and composition of the system and points out that the system can realize HD video transmission and video talkback between the surgery scene and the classroom.Thus, tech-nical level of clinical surgery teaching can be enhanced.

Objective To summarize the value of early mechanical ventilation plus continuous vacuum suction in treatment of serious pulmonary contusion.Methods Forty-eight cases of severe pulmonary contusion were assigned to mechanical ventilation plus continuous vacuum suction (observation group,n =20) and mechanical ventilation plus discontinuous vacuum suction (control group,n =28)according to the random number table.Modes of mechanical ventilation were synchronized intermittent mandatory ventilation (SIMV),pressure support ventilation (PSV),and positive and expiratory pressure (PEEP).Changes in blood gas analysis,mechanical ventilation time,and associated complications were compared between groups.Results At ventilation time of 6 and 24 hours,PaO2 in observation group was (100.36 ± 5.90) mmHg and (105.34 ± 7.40) mmHg respectively,with significant differences from (75.36 ± 8.95) mmHg and (76.36 ± 8.35) mmHg in control group (P ＜ 0.01).At ventilation time of 24 hours,PaO2/FiO2 was (283.50 ± 15.20) mmHg in observation group and (201.50 ± 10.20) mmHg in control group (P ＜0.01).Mechanical ventilation time and PEEP at ventilation time of 48 hours in observation group was (3.2 ± 1.1) days and (4.5 ± 2.3) cmH2 O,with significant differences from (6.5 ± 2.8) days and (8.5 ± 2.5) cmH2O in control group (P ＜ 0.01).Associated complications of the two groups revealed no significant difference (P ＞ 0.05).Conclusion Early mechanical ventilation with sustained vacuum suction is effective to keep airway clear,improve oxygenation index,decrease PEEP level,and control the duration of mechanical ventilation,but may not lower the risks of ventilator-associated pneumonia and pulmonary atelectasis.

Objective To assess the significance and the relationship of BODE index score and inflammation factors in stable chronic obstructive pulmonary disease(COPD).Methods Sixty COPD patients in their stable condition were evaluated for BODE index score and the level of tumor necrosis factor-α(TNF-α),interleukin-8(IL-8) and C reactive protein (CRP) were determined.Results BODE index score in COPD patients was positively correlated with serum concentrations of TNF-α,IL-8 (r =0.455,P ＜ 0.01 ; r =0.303,P ＜0.05),but not with CRP (r =0.111,P =0.398).IL-8 and TNF-α were both significantly negatively correlated to body mass index(BMI),force exhale volume of the first second (FEV1) and 6 minute walking distance (6MWD) (r=-0.417,P ＜0.01;r=-0.538,P＜0.01;r =-0.419,P＜0.01 for IL-8;and r=-0.262,P＜0.05;r=-0.348,P＜0.01;r=-0.334,P＜0.01 for TNF-α).Conclusion The BODE index,as a simple multidimensional grading system for COPD,is closely related to system inflammation,which indicates that system inflammation may contribute to the systemic development of COPD.

AIM:To analyze the accuracy and the influencing factors of LAMBDA100 retinometer in predicting the visual acuity of cataract patients with high axial myopia after phacoemulsification.METHODS: The retinal visual acuity was measured in 91 patients with 91 cataract eyes by LAMBDA100, and compared with the best corrected visual acuity 2wk after operations.If differences of predictive visual acuity and postoperative visual acuity between the two logarithmic visual acuity chart was within 2 lines, it was considered consistent.RESULTS: The total compliance rate was 62%, the false positive rate was 2%,the false negative rate was 36%.The predictive accuracy was affected by lens opacity, the deeper opacity, the lower accuracy.The predictive accuracy of eye with axial length ≥32mm was significantly lower than that of eye with axial length <32mm, the difference was statistically significant (P<0.05).The predictive accuracy rate of group that preoperative best corrected visual acuity was ≥4.0 was 75%;the predictive accuracy rate of group that preoperative best corrected visual acuity was <4.0 was 49%, the difference was statistically significant (P<0.05).CONCLUSION: LAMBDA100 can be used as an assistant tool for predicting postoperative visual acuity in immature stage cataract of patients with high myopia.The eye axial length, the degree of visual acuity and lens opacity can influence the predicting accuracy.

Objective To investigate the pharmacological mechanism of LXHX capsule. Methods The skin specimens from psoriasis patients were examined with TUNEL (terminal deoxynucleotidyl trans-ferase-mediated dUTP-biotin nick end labeling) technique to detect the apoptosis of keratinocytes. PCNA (proliferating cell nuclear antigen) detecting kits was used, too. Then, the flow cytometry, with AnnexinV/PI and PI dyeing method, was used to analysis the effect of LXHX capsule on apoptosis in cultured keratinocytes. Results There was an increasing of both cell apoptosis and proliferation in psoriatic epidermis and LXHX capsule could induce apoptosis. Conclusions The keratinocyte apoptosis and proliferation both increased in psoriasis, which reach a new balance in a higher level. LXHX capsule could induce apoptosis in vitro, which may be one of the pharmacological mechanisms of LXHX in treating psoriasis.
