ABSTRACT
@#Objective To investigate the value of chest high-resolution computed tomography (HRCT) score in evaluating the severity of hip fracture-induced early acute lung injury (ALI) in the elderly patients. Methods The clinical data of 289 elderly hip fracture patients in Chongqing Traditional Chinese Medicine Hospital from July 2014 to April 2020 were retrospectively analyzed. All patients were divided into two groups, including an ALI group (n=114, 36 males and 78 females at age of 82.94±6.85 years) and a non-ALI group (n=175, 51 males and 124 females at age of 84.42±6.31 years). General information, chest HRCT scores and PaO2/FiO2 were compared between the two groups. Correlation analysis was used to compare the relationship between chest HRCT scores and PaO2/FiO2. Multiple linear stepwise regression analysis was applied to evaluate the effective extent of the diffuse ground glass opacity (DGGO), intense parenchymal opacification (IPO), and reticulation HRCT scores to the overall HRCT scores. Results The DGGO scores, IPO scores, reticulation scores, overall HRCT scores and PaO2/FiO2 were higher in the ALI group than those in the non-ALI group (P<0.001). In the ALI group, correlation analysis showed that DGGO, overall HRCT scores were in significantly negative correlation with PaO2/FiO2 (P<0.001). In addition, the correlation among PaO2/FiO2 and overall HRCT scores was more significant than that of DGGO scores. Multiple stepwise regression analysis indicated that DGGO, IPO, and reticulation scores were independent influencing factors for overall HRCT scores. Among the influencing factors, DGGO scores had the greatest impact, then IPO scores and reticulation scores. The HRCT signs of DGGO, IPO, and reticulation appeared simultaneously had the greatest effects on the overall HRCT scores. Conclusion The chest HRCT score, which is associated with PaO2/FiO2, also can be used in the severity assessment of elderly patients with early ALI caused by hip fracture.
ABSTRACT
Currently, the outbreak of the new coronary pneumonia has entered a critical period of screening, prevention and control.In order to block the transmission of the virus in the radiology department, it is particularly important to effectively protect the medical servant while speeding up the flow of inspection.Based on the basis of notification of the bureau of disease control and prevention, the expert consensus of the CMA and CMDA, and the literature review, combined with the previous practical work experience,this article puts forward the recommendations on the important effect of nursing-technology integrated in the imaging examination of novel coronavirus pneumonia, in order to provide reference for the protection of medical servant in the radiology department at the front line of anti-epidemic.
ABSTRACT
Objective@#To investigate the related factors of unprotected sexual behaviors among male students who have sex with men in Beijing.@*Methods@#Male students who have sex with men were recruited from May 2018 to July 2018 at two voluntary counseling and testing (VCT) clinics in Beijing by convenient sampling method. Information being collected during in-depth personal interviews with a semi-structured outline included ways to seek sexual partners, sexual partners characteristics, attitude of condom use, incidence and causes of unprotected sexual behaviors, rush poppers and alcohol use. The text information was summarized and analyzed by Nvivo 11.0 software.@*Results@#A total of 35 male students who have sex with men were recruited and interviewed, the median of age was 22 years old (P25-P75: 21-24 years old). We found that incomprehensive knowledge of condom use, low risk perception of non-anal sexual behaviors, rush poppers and alcohol use were risk factors of unprotected sexual behaviors on individual level. Besides, sex with regular sex partners, partners who were much older or not from campus, and insertive partners are more likely to be unprotected. Furthermore, refusal of condom use by sexual partners and low self-efficacy of decision-making on condom use were the main reasons for unprotected sexual behaviors among male student who have sex with men.@*Conclusion@#Lack of condom use knowledge, low risk perception of non-anal sexual behaviors and insufficient ability to refuse non-condom requirements for regular sex partners, partners who were much older or not from campus, and insertive partners are related factors of unprotected sexual behaviors among male students who have sex with men.
ABSTRACT
Objective To explore CT angiography(CTA) method for the influence of the cerebral angiography ,looking for dif-ferent situations using which kind of scan mode can achieve the best results .Methods 350 CTA patients were selected and tested by 4 kinds of scanning methods which were subtraction scan (236) ,experience value scan (13) ,smart tracking scan (68) ,smart tracking and subtraction combined(33) .To compare and analyze that four kinds of scanning methods ,to explore which kind of method under what circumstances can get the best examination results .Results Smart tracking and subtraction combined with scan method and subtraction scan method for excellent rate of image quality were 93 .93% and 93 .64% respectively ,there were no sig-nificant statistical differences between them .Experience value method and smart tracking method for excellent rate of image quality were only 76 .92% and 66 .18% ,there was significant difference in statistics .Conclusion Subtraction scan can be used as a conventional scan method .In low dose test bolus of time-density curve detection failure cases ,smart tracking and subtraction combined with scan method was used to get the image quality with subtraction scan method ,it is an effective complement of subtraction scan method ,is worth generalization .
