OBJECTIVE To analyze occupational risk factors onto Central Sterile Supply Department(CSSD) staff caused by actual working conditions and provide correspondingly protective measures.METHODS Take actions,such as circulating the air inside working site,eliminating contamination which brought into by biological and chemical methods,and avoiding physical fatigue etc,which summarized by practical study and analysis on the(various) factors during daily work routine,e.g.physical factor,chemical factor,biological factor and psychological factor.RESULTS All methods mentioned in this article could improve self-protection awareness of CSSD staff and(enhance) the physical condition of staff as well as reduce pollution on environment.CONCLUSIONS For preventing the threats of occupational risk factors,it′s critical to reduce or eliminate the negative factors in CSSD.

Objective To evaluate the activation of the visual cortex in patients with primary openangle glaucoma (POAG) and to explore whether the neuronal activity corresponds with retinal nerve fiber layer (RNFL) and cup-to-disc (C/D) values.Methods Twenty-five patients and 25 gender-and agematched healthy volunteers were studied.Blood oxygenation level-dependent functional magnetic resonance imaging (BOLD-fMRI) and three-dimensional brain volume imaging (3 D BRAVO) sequences were obtained using 3 T MR imaging system.A full-screen black-white shift checkerboard was used for visual stimulus during the fMRI experiment and was performed on each eye of all subjects using a visual-acoustical system.All acquired data were postprocessed and analyzed by statistical parametric mapping (SPM).After analysis,individual activated mapping,intra-group mean activated mapping,and inter-group variant mapping were observed.The voxel number,intensity,and Montreal Neurological Institute (MNI) coordinate of the activated clusters were recorded.The Xjviewer software was utilized to obtain activated voxel numbers in occipital lobe.A Pearson correlated test was performed to test the correlation between the number of activated voxels and RNFL,C/D and Hodapp-Anderson-Parrish (HAP) clinical stage.Results Intra-group mean activated mappings of both patients and volunteers showed obvious activation in bilateral occipital lobes.As compared with healthy volunteers,the POAG patients exhibited statistically significantly decreased activation in bilateral occipital lobes,left hippocampus,and left cerebellum,along with lower mean RNFL [(71.56 ±21.54) i m versus (111.88 ± 9.96) μm] and higher C/D values (0.71 ± 0.18 versus 0.36 ± 0.08 ; t value was respectively-10.901 and 11.643,P ＜ 0.05).The number of activated voxels in the occipital lobes of POAG patients did not correlate with RNFL,C/D and HAP clinical stage of the corresponding eye (r value was respectively 0.157,-0.113 and-0.242,P ＞ 0.05).Conclusions fMRI demonstrated differences in visual cortex activation in POAG patients relative to healthy volunteers,suggesting it might be a promising complementary method for diagnosing glaucoma.However,fMRI findings did not correlate with POAG extent,as measured by RNFL and C/D values.Ophthalmological examination remains to play an important role in the evaluation of open-angle glaucoma.

Objective:To explore the establishment of a surgical complication monitoring mode based on data on the medical record homepage, and analyze its impact on the trend of changes in surgical complication incidence.Methods:A monitoring mode of surgical complication was developed based on the " structure-process-results" framework by using surgical complication rates derived from performance appraisal for a tertiary general hospital in Guangzhou. The number of surgical complications and the number of discharged surgical patients was collected from the hospital from January 2019 to June 2022 through the home page collection system for performance appraisal of national tertiary public hospitals. Descriptive analysis was used to analyze the incidence of surgical complications, and Joinpoint regression was used to analyze the trend of changes in the incidence of surgical complications. Monthly percentage change ( MPC) and average monthly percentage change ( AMPC) were calculated. Results:Since the hospital began implementing the surgical complication monitoring mode in May 2021, the incidence of surgical complications had decreased from 2.55% in June 2021 to 0.82% in June 2022, with an MPC of -5.58% ( P=0.024), which was better than the changes from January 2019 to May 2021 ( MPC=0.18%, P=0.755). Conclusions:The surgical complication monitoring mode constructed by the hospital can effectively reduce the incidence of surgical complications, providing reference for optimizing hospital′s medical quality management process and decision-making mode.
