Objective To investigate the current status of nursing information services on the hospital web sites,and provide empirical reference for the development of nursing information services. Methods Seventy three level hospitals were recruited in the study. The famous search engines such as Baidu and Google were used to locate the target hospital web sites. The nursing-related information was recorded and classified. Results Nursing related information could be found on 41(58.6%)hos-pital web sites. The data was not updated timely,and the click frequency was low. The contents were far of abundant and the presentation rates were under 25.0% except the contents of introduction to nursing and nursing news. Conclusions The nurs-ing-related information on the hospital web-sites were insufficient. Nursing administrators should pay close attention to the defi-ciency of nursing information on hospital web-sites and take actions to promote the development of nursing information ser-vices.

Objective To understand the status of knowledge,attitude and practice(KAP)of foodborne parasitic diseases among senior high school students in Three Gorges Reservoir Region. Methods A total of 1 353 senior high school students were selected with the cluster sampling method and investigated with the questionnaires in Zigui County,and the data were ana?lyzed statistically. Results Among the 1 353 students surveyed,the awareness rates of parasitic diseases,their hazards and transmissions were 62.23%(842 cases),80.78%(1 093 cases)and 83.89%(1 135 cases)respectively. The awareness rate of parasitic diseases in the students of senior Grade One was higher than that of Grade Two(χ2 =7.037,P<0.05). The formation rates of behaviors of refusing of raw food,refusing of unboiled water,and dining at home or school in the students of senior Grade One were higher than those of Grade Two(χ2=6.970,12.749 and 12.921 respectively,and all P<0.05). Fifty?one per?cent(690 cases)of students would not have the food with the infection risk of parasitic diseases. Conclusion The awareness of parasitic diseases of high school students in Zigui County is not efficient,and the health education should be strengthened.

Objective:To investigate the difference of amplitude and duration in submental muscles and infrahyoid muscles activities during pharyngeal swallowing between normal adults and post-stroke dysphagia by using surface electromyography technique and analysis system.Method:The clinical data from 30 cases of PSD and 30 healthy controls were collected.ME6000-T8-type sEMG machine was used to collect sEMG of two groups in resting state,saliva swallow and wet swallow,and therefore calculate the average amplitude and duration.Result:①In resting state:there were no statistical difference in the average amplitude of submental and infrahyoid muscles between PSD group and control group(P＞0.05);In PSD group:statistical differences were not observed in the amplitude between submental muscles and infrahyoid muscles;In control group:there were no statistical difference in the average amplitude between submental muscles and infrahyoid muscles;②During dry swallowing:the results indicated that the average amplitude of submental and infrahyoid muscles in PSD group were significantly lower than that in control group;and the duration of submental and infrahyoid muscles was significantly lower with statistical difference(P＜0.05).③During wet swallowing(swallowing5ml water):the average amplitude of submental and infrahyoid muscles in control group were significantly higher than that in PSD group(P＜0.005);and the duration of submental and infrahyoid muscles were also significantly prolonger (P＜0.001);④Intra-group comparison:statistically differences were not observed in the amplitude and duration between submental muscles and infrahyoid muscles for both PSD group and control group(P＞0.05).Conclusion:sEMG could be used as a non-invasive、simple、rapid tool in detecting the sEMG activities of related muscles during pharyngeal swallowing.The average amplitude and duration of submental and infrahyoid muscles can not only preliminarily screen and evaluate swallowing function,but also reflect the complexity and the elevation persistence time of the hyoid bone and the larynx in elevation movement,which were used to evaluate the neuromuscular function and predict the risk of aspiration of patients.

Objective:To develop an total knee arthroplasty(TKA) enhanced recovery after surgery information management system based on "cloud + terminal" data-drivene technology, which can be used in the perioperative interaction between doctors and patients and rehabilitation management of TKA, and evaluate its implementation effect.Methods:The clinical data of 96 patients with unilateral TKA from Qilu Hospital Shandong University were analyzed retrospectively. Forty eight patients in the control group from February to August, 2018 were treated with traditional management. From February to August, 2019, 48 patients in the research group adopted the accelerated rehabilitation information management system based on data-driven technology, which can automatically match, interact and push the information between medical and patient.Results:The Self-rating Anxiety Scale(SAS) score of the intervention group on hospitalization day was 41.52±4.65, which was better than that of the control group (52.60±4.84). The difference between the two groups was statistically significant ( F value was 11.446, P<0.05). The scores of Hospital for Special Surgery(HSS), Visual Analogue Scale(VAS) and SAS in the intervention group 3 days after operation were 56.31±5.81, 2.79±0.68, 38.69±3.81, which were better than those of the control group (51.31±5.20, 4.31±0.78, 46.02±3.86). The difference between the two groups was statistically significant ( F value was 4.44, 10.19, 9.37, all P<0.05); the HSS, VAS, and SAS scores of the intervention group one week after operation were 71.35±3.59, 1.98± 0.67, 36.81±4.03, better than the control group (67.15±3.67, 2.60±0.87, 39.48±4.04), the difference between the two groups was statistically significant ( F value was 5.683, 3.951, 3.237, all P<0.05); the postoperative hospital stay in the intervention group was (3.98±0.84) days, which was less than (6.00±0.80) days in the control group, the difference was statistically significant ( F value was 146.286, P<0.05); The patients′ satisfaction score in the intervention group during medical treatment was 97.46±1.73, which was higher than the control group (94.35±2.04), the difference was statistically significant ( F value was 64.911, P<0.05). Conclusions:TKA enhanced recovery management system based on "cloud + terminal" data-drivene can improve the management level of TKA patients, reduce the length of stay and improve satisfaction of patients.

Objective To evaluate the merits and demerits of three different closure methods for femoral artery access site in the interventional therapeutic procedures for senile patients with coronary artery disease. Methods We managed the femoral artery access sites in 60 cases undergoing interventional operation using three different hemostasias, including manual compression, Femostop equipment and Perclose suture (20 cases for each group).
