Objective:To investigate the correlation between hematopoietic cell kinase (HCK) and the expression level of the mitochondrial ribosomal protein L13 (MRPL13) and hematopoietic multimode ultrasound.Methods:204 female breast cancer patients treated by surgery in Quzhou people’s Hospital from Jan. 2017 to Sep. 2020 were selected as study subjects. Breast cancer tissues and adjacent normal tissues were extracted intraoperatively. Preoperative conventional ultrasound, shear wave elastography (SWE) and contrast-enhanced Ultrasonography (CEUS) were used to detect HCK and MRPL13 expression levels. Univariate analysis and binary Logistic regression were used to analyze the correlation between multi-mode ultrasonic features and HCK and MRPL13.Results:The positive expression ratios of HCK and MRPL 13 in breast cancer tissues were significantly higher than those in adjacent tissues ( χ2 was 5.625, 7.197; P was 0.018, 0.007) . In conventional ultrasound features, the proportions of HCK-positive breast cancer patients with irregular mass edges, microcalcifications, and grade II to III blood flow classification were significantly higher than those of HCK-negative patients ( χ2 was 7.437, 16.684, 23.262; P was 0.006, <0.001, <0.001) ; The proportion of MRPL13-positive breast cancer patients with a maximum diameter of ≥2 cm, irregular edges of the tumor, and grade II-III blood flow classification was significantly higher than that of MRPL13-negative patients ( χ2 was 4.676, 11.118, 8.389; P was 0.031, 0.001, 0.004) . For SWE signs, the proportion of HCK positive breast cancer patients with hard ring sign was significantly higher than that of HCK negative patients ( χ2=11.220, P=0.001) ; the proportion of MRPL13 positive breast cancer patients with hard ring sign and black hole sign was significantly higher than that of MRPL13. Those who were negative ( χ2 was 4.482, 8.775; P was 0.034, 0.003) . Among CEUS characteristics, the proportion of HCK-positive patients with high enhancement was significantly higher than that of HCK-negative patients ( χ2=7.356, P=0.007) ; the proportion of MRPL13-positive patients with high enhancement and late regression was significantly higher than that of MRPL13-negative patients ( χ2 was 9.165, 7.631; P was 0.002, 0.006) . The results of binary logistic analysis showed that there was microcalcification ( OR=4.619, 95% CI=2.657-8.119, P=0.009) , blood flow classification II to III ( OR=4.150, 95% CI=2.547-7.954, P=0.015) and high enhancement of CEUS ( OR=4.150, 95% CI=2.547-7.954, P=0.015) are independent risk factors for positive expression of HCK; blood flow grade II to grade III ( OR=4.213, 95% CI=3.145-8.557, P=0.012) , appearance of black hole sign ( OR=5.246, 95% CI=2.864-10.378, P<0.001) and high enhancement of CEUS ( OR=3.872, 95% CI=1.887~6.438, P=0.026) were the independent risk factors for the positive expression of MRPL13. Conclusion:The multimodal ultrasonographic features of breast cancer are helpful to predict the expression levels of HCK and MRPL13, so as to provide new imaging ideas for early diagnosis of breast cancer, the designation of treatment options and the preoperative non-invasive assessment of breast cancer prognosis.

Objective To investigate whether serum level of low-density lipoprotein cholesterol can predict the expan?sion of hemorrhage growth in elderly male patients with acute hypertensive intracerebral hemorrhage. Methods Patients (n=108) who visited our hospital with from June 2012 until May 2014 spontaneous hypertensive intracerebral hemorrhage with?in 6 hours of onset which is confirmed by initial computed tomography (CT) were sent to repeated CT within 24 hours of on?set. All selected patients were divided into the LDL-C≥2.49 mmol/L group and LDL-C<2.49 mmol/L group. Clinical data of these 2 groups were compared and the relationships of hematoma growth and its risk factors were analyzed. Results Baseline blood pressure, the level of blood glucose, PT, APTT, FIB, PLT and hemorrhage volume did not differ significantly between the LDL-C≥2.49 mmol/L group and LDL-C<2.49 mmol/L group. The ratio of hemorrhage growth in LDL-C<2.49 mmol/L group was significantly higher than that in LDL-C≥2.49 mmol/L group (34.21%vs 11.43%). Multiple logistic regres?sion analysis showed that LDL-C<2.49 mmol/L was the only risk factor contribute to hemorrhage growth. Conclusion Pa?tients with LDL-C<2.49 mmol/L in acute intracerebral hemorrhage are of high risk of hemorrhage growth so early attention and appropriate procedure are needed to prevent or slow its growth.
