Objective To compare the durability and cost-effectiveness of slightly acidic electrolyzed oxidizing water(SAEOW),ortho-phthalaldehyde (OPA) and glutaraldehyde (GA) in two conditions,i.e.,continuous machine cleaning and continuous manual cleaning.Methods The maximal numbers of endoscopes which were disinfected by the three disinfectants at its minimal effective concentration,as well as the corresponding costs were compared.The cost-effectiveness of three disinfectants were evaluated with revenue-incremental cost analysis.Results The number of endoscopes disinfected by ortho-phthalaldehyde was larger than that by two other disinfectants,140 ± 2 by machine wash and 226 ± 1 by hand washing;followed by glutaral disinfectant,88 ± 2 and 108 ± 2 by machine wash and hand wash,respectively;slightly acidic electrolyzed oxidizing water disinfected the least endoscopes,34 ± 2 and 39 ± 1 by machine wash and hand wash.There were significant differences among these three disinfectants (all P ＜ 0.05).Compared with GA,one more Yuan invested to OPA yielded 2.24 yuan more under the condition of machine wash and 3.14 yuan more under the condition of hand wash.Compared with GA,one Yuan invested in SAEOW produced 47.14 yuan by machine wash and 45.6 Yuan by hand wash.Conclusion Under full workload,orthophthalaldehyde shows the best durability among the three disinfectants,while slightly acidic electrolyzed oxidizing water shows the highest economic benefit.

Objective To assess regional left ventricular systolic function in patients with hypertrophic cardiomyopathy (HCM) using real-time three-dimensional echocardiography (RT-3DE).Methods Twenty-five patients with HCM which was asymmetric septal hypertrophy,and twenty healthy subjects were enrolled in the study.The apical four-chamber view of left ventricular was acquired by RT-3DE.The left ventricular volume-time curves were analyzed quantitatively with Tomtec 4D LV-Analysis 3.0,and regional end-diastolic volume and end-systolic volume of left ventricular (rEDV,rESV),the time to minimum systolic volume (rESVT),regional stroke volume (rSV),regional ejection fraction (rEF),regional-global ejection fraction (rgEF) and the parameters of left ventricular dyssynchrony were measured.Results In the HCM group,the values of Tmsv16-Dif,Tmsv16-SD,Tmsv16-Dif％,Tmsv16-SD％ were significantly lower compared with the control group (P ＜ 0.01),and rEDV,rSV,rEF and rgEF in hypertrophic segments were lower than those in non-thickening and mild-thickening segments (P ＜0.05).In the control group,there were no significant difference of those parameters among all segments (P ＞0.05).The values of rEDV,rSV and rgEF in hypertrophic segments decreased in the HCM group (P ＜0.05),at the basal level,rEF in hypertrophic segments decreased,at the apical level,it increased,but the differences at the mid-ventricular level between the two groups were not significant;the values of rEF and rgEF in non-thickening and mild-thickening segments increased (P ＜0.05).Conclusions RT-3DE could sensitively detect left ventricular dyssynchrony and accurately assess regional left ventricular volume and function of different segments in patients with HCM.

Objective:To understand the iodine content of edible salt in residents of Xinjiang Production and Construction Corps (referred to as Corps), and provide scientific evidence for prevention and treatment of iodine deficiency disorders.Methods:According to the requirements of the "National Iodine Deficiency Disorders Surveillance Program" form 2015 to 2019, in accordance with the principle of random sampling, one regiment from each of the five directions of east, west, south, north and center in the Corps was selected, and four companies were selected from each regiment. Edible salt samples from the homes of 15 residents in each company were collected, and salt iodine content was quantitatively tested and the test results were analyzed.Results:From 2015 to 2019, 21 028 household salt samples were collected, qualified iodized salt were 20 204, non-qualified iodized salt were 712, non-iodized salt were 112, iodized salt coverage rate was 99.47% (20 916/21 028), iodized salt qualified rate was 96.60% (20 204/20 916), qualified iodized salt consumption rate was 96.08% (20 204/21 028). The average salt iodine content was (27.72 ± 4.81) mg/kg. From 2015 to 2019, the iodized salt coverage rates in the whole Corps were all > 95%, and the iodized salt qualified rates and the qualified iodized salt consumption rate were all > 90%. Among the 14 divisions of the Corps, iodized salt coverage rates were all > 95%, except for the 12th and 14th divisions, where the iodized salt qualified rates and qualified iodized salt consumption rates were < 90%, all other divisions were > 90%.Conclusions:Iodized salt coverage rate, iodized salt qualified rate and qualified iodized salt consumption rate have all reached the national standard for eliminating iodine deficiency disorders from 2015 to 2019, however, non-iodized salt exists in some areas, and the qualified iodized salt consumption rate is low. We should strengthen monitoring of iodized salt in key areas and promote health education, consolidate and maintain achievements in eliminating iodine deficiency disorders.

To evaluate the feasibility of real-time myocardial contrast echocardiography (RTMCE) by quantitative analysis of myocardial perfusion in rabbits, transthoracic RTMCE was performed in 10 healthy rabbits by using continuous infusion of SonoVue into the auricular vein. The short axis view at the papillary muscle level was obtained. The duration of the time that the contrast took to appear in right heart, left heart and myocardium was recorded. The regional myocardial signal intensity (SI) versus refilling time plots were fitted to an exponential function: y(t) =A(1-e(-beta(t-t0))) + C, where y is SI at any given time, A is the SI plateau that reflects myocardial blood volume, and beta is the slope of the refilling curve that reflects myocardial microbubble velocity. The A, beta and Axbeta values at different infusion rate of SonoVue were analyzed and the A, beta and Axbeta values in each segment in the short axis view at the papillary muscle level were compared. All the animal experiments were successful and high-quality images were obtained. The best intravenous infusion rate for SonoVue was 30 mL/h. The contrast appeared in right heart, left heart and myocardium at 7.5+/-2.2 s, 9.1+/-2.4 s and 12.2+/-1.6 s respectively. After 16.6+/-2.3s, myocardial opacification reached a steady state. The mean A, beta and Axbeta value in the short axis view at the papillary muscle level were 9.8+/-3.0 dB, 1.4+/-0.5 s(-1) and 13.5+/-3.6 dBxs(-1) respectively. A, beta and Axbeta values showed no significant differences among 6 segments. It was suggested that RTMCE was feasible for quantitative analysis of myocardial perfusion in rabbits. It provides a non-invasive method to evaluate the myocardial perfusion in rabbit disease models.

Objective: To analyze the delay of seeking medical treatment and associated factors among students with tuberculosis in Shaanxi Province from 2015 to 2019, so as to provide scientific evidence for the early detection and control of tuberculosis epidemics in schools. Methods: Data from 6 739 students with pulmonary tuberculosis registered in Shaanxi Province from 2015 to 2019 were collected from the TB Management Information System of China Information System for Disease Control and Prevention. Univariate and multivariate Logistic regression analyses were used to analyze the characteristics and influencing factors of pulmonary tuberculosis patients. Results: Among 6 739 cases of students with pulmonary tuberculosis from 2015 to 2019 in Shaanxi Province, 3 040 patients delayed seeking medical treatment. The rate of delayed treatment was as high as 45.1%, and the median delayed treatment time was 38(24, 68) days. From 2015 to 2019, the overall delay rate of students showed a downward trend, with a significant difference(χ 2=120.45, P<0.05). Univariate analysis showed that there were statistically significant differences in delay rate between different patient sources, diagnosis results and regions(χ 2=274.19, 26.75, 24.12, P<0.05), among which for factors such as tracing, tuberculosis pleurisy, doctor delay in the northern part of Shaanxi, the rates were higher. The results of multivariate Logistic regression analysis showed that the regions of northern Shaanxi(OR=2.74), central Shaanxi(OR=2.09), and southern Shaanxi(OR=2.39), and clinical consultation(OR=1.84), recommendation(OR=2.81), tracing(OR=3.28), and tracing (OR=6.07) were risk factors for delay of consultation. A lack of etiology results(OR=0.47) was to protect delay of consultation. Conclusion From 2015 to 2019 in Shaanxi Province, a delay in seeking medical treatment was relatively common among students with tuberculosis. The region, source of patients and diagnosis results were factors that influenced the delay in finding tuberculosis patients in Shaanxi Province.

To analyze the fuzzy language and explore the translation methods of the fuzzy language in traditional Chinese medicine,examples are given and discussed in this essay.Based on the analysis of the problems in the application of the fuzzy theory to TCM translation,a flexible translation method like a combination of multiple translation method has been suggested in addition to appropriate translations such as transliteration,literal translation,free translation and borrowing translation,which can promote understanding the characteristics of the fuzzy language in TCM so as to further boosting the communication of TCM culture.
