OBJECTIVE To evaluate the feasibility and sterile effect of low-temperature plasma sterilizer produced by Chinese Academy of Sciences for the sterilization of arthroscope surgical instruments.METHODS To explore the cleaning,package,arrangement and sterile effect monitoring of instruments in the process of arthroscope sterilization using low-temperature plasma sterilizer.RESULTS In the sterilization process of arthroscope surgical instruments using low-temperature plasma sterilizer,the chemical indicators and indicating patch were discolored,the monitoring of bio-box and the sterilization monitoring of surgical instruments were all negative.CONCLUSIONS Using the low-temperature plasma sterilizer machine for the sterilization of endoscope surgical instruments can ensure the security of sterilization,make less injury of precise instruments,shorten the sterilization time,accelerate the surgical turnover,enhance the frequency of surgical instruments application,and increase the efficiency.

Objective?To explore the effects of ideation and imitation behavior training on rehabilitation in patients with chronic schizophrenia. Methods?Totally 200 schizophrenia patients admitted and treated in 2016 from Fuzhou Neuro-Psychiatric Hospital were selected and equally randomized to treatment group (n=100) and control group (n=100) according to the random number table. Patients in the control group received conventional nursing, while patients in the treatment group received ideation and imitation behavior training for 8 weeks on this basis. Wisconsin Card Sorting Test (WCST), Nurses' Observation Scale for Inpatient Evaluation (NOISE) and Personal and Social Performance Scale (PSP) were used to compare the rehabilitation effects between the two groups. Results?After intervention for 8 weeks, the score for correct response in WCSI in patients in the treatment group was (24.78±7.39), higher than that of patients in the control group, and the score for continuous mistakes in WCSI in patients in the treatment group was (14.78±5.27), lower than that of patients in the control group (t=3.800, 3.640;P＜0.01). After intervention for 8 weeks, the scores for NOISE (200.06±26.09) and PSP (79.83±4.21) in patients in the treatment group were higher than those of patients in the control group (t=6.880, 19.040;P＜0.01). Conclusions?Ideation and imitation behavior training helps to improve the patients' cognitive performance, including attention, memory, linguistic competence and reasoning ability, as well as self-care ability of daily living and social function, and promotes chronic schizophrenia patients' rehabilitation.
