RESUMEN
Objective:To analyze the application of Cho peak value and color doppler ultrasound blood flow score in the early diagnosis of breast cancer, and to evaluate the relationship between Cho peak value, blood flow score, TNM stage and prognosis quality.Methods:A total of 82 patients with breast cyst admitted from Jan. 2015 and Dec. 2019 were selected as subjects for the study. ROC curve was used to compare the ability of color doppler flow score and functional magnetic resonance imaging (fmri) in the diagnosis of breast cancer when used alone or in combination. Logistic regression model was used to analyze the factors affecting the prognosis quality and TNM staging of patients.Results:The breast cancer group’s Cho value and blood flow signal score were significantly higher than the benign breast lesion group, and the difference was statistically significant (Cho value: t=43.977, P<0.001; blood flow signal score: t=22.071, P<0.001) ; The sensitivity, specificity and AUC of MRS combined with Doppler ultrasound for differential diagnosis of breast cancer are significantly higher than MRS or Doppler ultrasound alone, and the difference was statistically significant (sensitivity: χ2=4.514, P=0.016; specificity: χ2=4.858, P=0.013; AUC: Z=5.251, P<0.001) ; Cho value of patients with good prognosis group ( t=3.984, P<0.001) and blood flow signal score ( t=4.213, P<0.001) were significantly lower than those in the poor prognosis group; Cho value ( t=3.612, P<0.001) and blood flow signal score ( t=3.835, P<0.001) of TNM stage 0-Ⅱ patients were significantly lower than those of stage Ⅲ-Ⅳ group, the difference was statistically significant; the Cho value of the MRS scan and the patient’s prognosis quality ( OR=1.837, 95% CI=1.210-2.788, P=0.004) and TNM stage ( OR=1.818, 95% CI=1.224~2.702, P=0.003) was significantly positively correlated. The blood flow signal and the patient’s prognostic quality ( OR=1.906, 95% CI=1.105~3.287, P=0.020) and TNM stages ( OR=1.799, 95% CI=1.232-2.626, P=0.002) also showed a significantly positive correlation. Conclusion:The combination of Cho peak value and color doppler ultrasound blood flow score can significantly improve the early diagnosis efficiency of breast cancer, and Cho peak value and blood flow score are independent factors affecting TNM staging and prognosis.

Objective To investigate the braking time in diagnosis of lipohemarthrosis by ultrasound. Methods Experiment group:After 20 tubes containing fresh blood and pig marrow were uniformly mixed, they were instantly continuously detected by high-frequency linear array transducer in fixed-area at short-interval.Clinical group: Ten walking patients with lipohemarthrosis were examined with continuous detection by ultrasound,CT and MR before operation.Results Experiment group: Cloudy echo and slowly floating up of lipoids were detected at the beginning.After 2.7 to 3.7 minutes (average 3.17 minutes), the liquid was divided into two layers with vague boundary.After 5.3 to 8.0 minutes (average 6.75 minutes) ,the liquid was divided into 3 layers with thickening serum laye.Clinical group: Ultrasound findings: Cloudy medium echo was detected at first.After 2.0 to 4.0 minutes (average 3.08 minutes),the liquid was divided into two layers.After 4.4 to 10.0 minutes (average 6.92 minutes) , the liquid was divided into 3 layers with thickening serum layers.Three knees showed fracture line and 2 knees with occult fracture were diagnosed as lipohemarthrosis.CT and MR findings: Ten knees showed fracture line in CT examination,of which 7 knees showed double liquid-liquid layer and 3 knees showed single liquid-liquid layer in the suprapatellar bursa.Ten knees showed fracture line in MR examination,6 knees showed double liquid-liquid layer and 4 knees showed single liquid-liquid layer in the suprapatellar bursa. Conclusions The best braking time in diagnosing lipohemarthrosis by ultrasound can be shorten to 10 minutes and the necessary braking time is 2 to 4 minutes.
RESUMEN
OBJECTIVE To understand the present situation of hand hygiene execution rate among clinical medical personnel,and discuss a series of scientific,reasonable and practical hand hygiene intervention methods,in order to elevate the hand hygiene execution rate among medical personnel.METHODS Using the self-designed questionoaires in combination with observation on hand hygiene process and investigation of hand hygiene knowledge level among medical personnel in various departments of different levels of hospitals to assess the hand hygiene execution rate.RESULTS The investigation indicated 76.00% medical personnel have had hand hygienic knowledge training,and referred in the stipulation health drafts,the hand hygiene execution rate was 50.00-70.00%.The hand health execution rate before contact with patients was 59.82%,and after contacts with patients was 77.97%;among department the hand hygiene execution rate before contact with patients was highest in the department of pediatrics(82.78%),the lowest was in emergency department(11.11%),after contact with patients the highest was department of infectiong(100.00%),and the larest was in the internal medicine department(39.93%).CONCLUSIONS Medical personnel's hand hygiene consciousness is still weak,with lacked hand hygiene related knowledge,it is necessary to summarize a set of reasonable effective intervention plans to elevate the hand hygiene execution rate,reduce the hospital infection percentage,and lower the patient pain and the economic loss.
