Chinese Journal of Practical Nursing 2017;33(11):831-834
Objective To explore the role of rescue video logical slice and interactive analysis in the continuous improvement of quality of emergency care of multiple injury. Methods To establish a management team for the rescue video interactive analysis. From May, 2015 to April, 2016, every Wednesday from 8:00-11:00 am, the data of multi-injury patients registered in our management software of critical emergency cases were selected. A typical case study of the rescue video logical slices were processed through sorting the video cases in the video surveillance system installed in the emergency room. According to the characteristics of diagnosis and treatment of multiple injury, the evaluation indexes of nursing quality in emergency treatment of multiple injury were formulated and video data was analyzed interactively by using the failure mode analysis and root cause analysis. Based on the above analyzed results, the quality of emergency care of Multiple Injury was controlled and improved. Before and after performing the rescue video logic slices and interactive analysis management, the examined results of multiple injury first-aid nursing quality index, as well as the rate of patients satisfaction and nursing defects were compared. Results Before the implementation of the above method, the time of emergency treatment for multiple injury, the rate of patients with successful rescue, the rate of patient transport defect and the rate of missing items in the rescue unit were respectively as follows:(87.1±7.4)min, 90.77%(59/65), 30.77%(20/65), 12.31%(8/65),whereas after the implementation, the relevant data were (57.5 ± 5.2) min, 100.00%(68/68), 10.29%(7/68), 2.94%(2/68). The comparative difference before and after the implementation was statistically significant (t=26.84, χ2=2.15, 2.72, 1.72, all P < 0.05). Besides, the satisfaction with the various evaluations of patients′ family members was increased and the differences were statistically significant (χ2=15.45-23.21, P<0.05). Conclusions The introduction of rescue video slices and interactive analysis can effectively reduce the patient′s rescue time, improve the success rate of patients rescues, decrease the rate of patient transport defect and missing items in the rescue unit, effectively control the quality of links, improve the management efficiency, and thus realize the standardized management under normal working condition.

Objective Mitochondrial DNA (mtDNA) may be the target of oxygen free radicals related to Helicobacter pylori (H.pylori) infection, partly because of lack of protective histones and partly because of inefficient DNA repair systems. In this study we investigated the relationship between mitochondrial microsatellite instability (mtMSI) as well as integration of mtDNA in the nuclei of gastric mucosa and H.pylori infection. Methods H.pylori was detected using PCR and modified Giemsa staining. The mtMSI and the sequences of mtDNA in the nuclei were detected by PCR SSCP and in situ hybridization. Results The mtMSI was detected in 11 of 30 (36.7%) cases of gastric cancers, 2 of 15(13.3%) of intestinal metaplasia, 2 of 10 of dysplasia and 1 of 10 of chronic atrophic gastritis. The integration of mtDNA in the nuclei was detected in 20.0% (6/30) of gastric cancer, 1/10 of dysplasia, 6.7%(1/15)of intestinal metaplasia and 1/10 of chronic atrophic gastritis. The frequencies of mtMSI and integration of mtDNA in H.pylori positive group (12/39 and 8/39) were each significantly higher than those in H.pylori negative group (4/36 and 1/36, P 0.05), mtMSI and integration of mtDNA in the nuclei tended to occur in gastric mucosa with cagA positive H.pylori infection(10/25,6/25), but less often to occur in gastric mucosa with cagA negative H.pylori infection(2/14, 2/14). Conclusions The mtMSI and integration of mtDNA may be involved in the carcinogenesis of gastric mucosa and H.pylori infection might contribute to the mtMSI and integration of mtDNA.

Objective:To analyze the causes of SARS-CoV-2 nosocomial infection among healthcare workers (HCWs) and explore the effective precaution strategies in Emergency Center.Methods:The data of SARS-CoV-2 infected HCWs from January 5 to March 2, 2020 were retrospectively analyzed and compared under different conditions in Emergency Center of Zhongnan Hospital of Wuhan University.Results:Totally 13 SARS-CoV-2 infected HCWs (12 confirmed cases and 1 suspected case) were included in this study. The overall infection rate was 17.8% (13/73). The infection rates in outpatient/rescue room, isolation observation room and isolationin patient ward were 11.8% (4/34), 20.0% (3/15), 25% (6/24), respectively. The infection rate of physician was 13.0% (3/23), and the infection rate of nurse was 20.0% (10/50). All the infected HCWs had the definite exposure with confirmed or suspected COVID-19 patients. One asymptomatic cases were identified by laboratory findings of SARS-CoV-2 infection screening. There was no new confirmed SARS-CoV-2 infected HCWs after February 5, 2020. All the infected HCWs were cured.Conclusions:Under the epidemic of COVID-19, HCWs of Emergency Center have a high risk of occupational exposure and infection, especially for staffs working in COVID-19 isolation units. Scientific prevention and control management can effectively reduce the risk of SARS-CoV-2 infections and ensure the occupational safety for HCWs in Emergency Center.

OBJECTIVEFace-to-face interview (FTFI) and polling booth survey (PBS) were applied to compare the high risk behavior among HIV-positive clients of female sex workers (CFSWs).
METHODSThis study was conducted in antiretroviral therapy (ART) out-patients centers in Hengyang city, where clients who had been informed on their HIV-positive status for 6 months or longer were recruited. FTFI was first used to tackle on 8 sensitive questions related to sexual behavior, followed by PBS to poke on the same questions. Results from FTFI and PBS were then compared.
RESULTSCompared with FIFI, results in the PBS showed higher proportion of participants who reported "having had history of sexually transmitted diseases before knowing that they were infected with HIV" (40.6% vs. 24.2%) but lower proportions on "frequency of having sex with regular sexual partner less than 4 times per month" and "using condoms consistently with regular sexual partners in past 6 months (44.4% vs. 63.0%)". There were no significant differences in the remaining 5 questions shown in the results from the two methods.
CONCLUSIONHIV-positive CFSWs continued to practice unsafe sexual behaviors after knowing their HIV related status. Compared with FTFI, PBS seemed to have revealed higher proportion of unsafe sex behaviors, so as to generated more reliable data. While comparing with PBS, the traditional FTFI might have underestimated the risk behaviors among those HIV-positive CFSWs.
