Journal of Third Military Medical University 1988;0(05):-
An inflatable liquid epidural balloon was used to simulate an intracranial space-occupying lesion.Two groups of dogs with 8 in each were employed.Under different conditions and time intervals,intracranial pressure(ICP)was continuously recorded,and pressure-volume index(PVI),volume-pressure response(VPR),and cerebrospinal fluid pulse pressure(CSFPP)were measured silmutaneously.It was found that PVI was in significant negative linear correlation with ICP,while VPR and CSFPP in significant positive linear correlation with IVP(P
2.Analysis on the prognosis effect after health management intervention of chronic prostatitis
Chinese Journal of Health Management 2008;2(3):143-145
Objective To investigation the relationship between health management and prognosis of chronic prostatitis. Methods Three hundied and forty-six cases of chronic prostatitis were divided into two groups. The control group treatment was local washing and medicine for three months. The experiment group treatment was local washing, medicine, and health management for three months. NIH-CPSI was used for the results. Results There was no significant different between the experimental group(165 cases)and the control group(154 cases)before treatment in NIH-CPSI. The effective rate of the the experimental group was 88.5%, and that of the control group was 64.9% after treatment. It is effective for cure and the prognosis of the experiment was better than the control (P<0.05). Conclusion It is suggested that it is more effective for the prognosis of chronic prostatitis after the intervention of health management.
3.Presentation and DSP Implementation of Wavelet Zero-cross Stimulation Strategy for Cochlear Implants
Chinese Medical Equipment Journal 2003;0(11):-
Objective To introduce the wavelet zero -cross stimulation algorithm and based on which to design and implement the cochlear implants. Methods Through DSP and ICETEK-VC5416, the WZS speech coding strategy was simulated, and also the presented WZS strategy was compared to CIS strategy by hardware implementation and computer simulation. Results The processed audio signals, output from eight channels, were synthesized and played through loudhailer and could be heard with high fidelity. Conclusion The wavelet zero-cross stimulation(WZS) strategy, which generates stimulating pulsatile series at zero-cross points in the domain of wavelet transform, can keep the temporal correlation and coherence of speech remained in stimulating pulsatile series and reflects the characteristic of temporal coding for cochlea.

To evaluate the influence of different brands of syringes on performance parameters and application quality of syringe pump, we carried out matching experiment of infusion/syringe pump analyzer Rigel Multi-Flo, made by ALK Co. in Sweden, for 3 different types of syringes to measure the flow rate, occlusion alarm pressure, occlusion time and bolus volume of 26 syringe pumps. Data of quality control were analyzed with statistical method. The results demonstrated that there were significant differences in the flow rate, occlusion alarm pressure, occlusion time and bolus volume (P<0. 01) between those of common syringes and original syringes. This study points out that the health care providers should select compatible syringes for syringe pumps, which provides evidence and guidance to assure the reasonable and safe application of syringe pumps in clinical practice.

Objective To analyze the implementation effects of peer-assisted learning on critical thinking ability of undergraduate nursing students. Methods A total of 411 college nursing students were selected with 203 students of Class One, Class Three, and Class Five from Grade 2012 majoring in nursing were taken as the control group, 208 students of Class Two, Class Four, and Class Six as the experimental group. In the course of basic nursing practice, the control group was trained by the traditional practice, and the experimental group was trained by the way of peer mutual aid. Critical thinking disposition inventory Chinese version (CTDI-CV) was adopted to evaluate the level of critical thinking ability of the nursing students of both groups. SPSS 17.0 was used and the data of the two groups were compared by t test. Results The score of experimental group students' critical thinking ability and the score of 7 dimensions including their seeking truth, analysis ability, self-confidence, inquisitiveness, cognitive maturity, open mind and systematic ability were higher than those before the experiment (P<0.05). The total score of the experimental group students' critical thinking ability and the score of 5 dimensions including seeking truth , analysis ability, self-confidence, curiosity and cognitive maturity were higher than those of the control group (P<0.05). Conclusion Peer-assisted learning is beneficial to the improvement of critical thinking ability of nursing undergraduate students.
