ABSTRACT
Objective@#To retrospectively investigate the value of contrast enhanced ultrasound (CEUS) in breast cancer biopsy.@*Methods@#A total of 49 consecutive patients with biopsy confirmed breast cancer were retrospectively analyzed. All patients underwent CEUS and biopsies were thus performed targeting both the high perfusion and low/non-perfusion regions on CEUS. The diagnostic performance and core cancer involvement of the biopsy cores taken from the high perfusion regions were compared with those from the low/non-perfusion.@*Results@#A total of 53 breast cancer lesions were biopsy confirmed in 49 patients.CEUS revealed homogeneous enhancement in 8 lesions (15.1%), and heterogeneous enhancement in 45 lesions (84.9%). The diagnostic accuracy rate for biopsy cores taken from the high perfusion regions was significantly higher than that from the low/non-perfusion regions (98.5% vs 72.9%, P<0.01). The core cancer involvement was also higher in high perfusion lesions (55% vs 30%, P<0.01).@*Conclusions@#CEUS can differentiate the active area and necrotic fibrosis area of breast tumors by displaying the microvessels, thus contributing to the selection of biopsy sites.

ABSTRACT
Objective@#To examine the relationship between obesity and carotid intima-media thickness (cIMT) in children and adolescents in order to provide scientific evidence for the prevention and control of cardiovascular diseases.@*Methods@#A total of 289 children and adolescents aged 6 to 17 years were included in the study, and weight, height, blood pressure and cIMT were measured. Multivariable Logistic regression model was used to analyze the relationship between obesity and cIMT.@*Results@#The level of cIMT and prevalence of high cIMT in obese males were higher than those in non-obese males(P<0.05), while there was no statistical significance between two weight groups in females (P>0.05). After adjusted for sex, age and blood pressure, compared with the non-obese children and adolescents, the odds ratios (OR s) of obesity for high cIMT in total sample, males and females were 3.03 (95%CI=1.11-8.28), 4.32 (95%CI=1.23-15.21) and 1.45 (95%CI=0.23-9.37) respectively.@*Conclusion@#Obesity may increase cIMT levels and risk of high cIMT in children and adolescents. Effective measures should be taken to prevent and control the obesity, and to reduce the risk of abnormal vascular structure in children and adolescents.
ABSTRACT
Objective@#To examine the relationship between clustering of metabolic disorders and left ventricular hypertrophy (LVH) in hypertensive children and adolescents, and to provide the reference for preventing the damage to their heart structure.@*Methods@#Based on the data from the Twelfth Five-year National Science and Technology Support Program “Early Warning, Diagnosis and Treatment of Cardiovascular Disease in Children” from September 2012 to September 2014 in Jinan, 261 children and adolescents aged 6-17 years whose hypertensive status was confirmed based on appearance of elevated blood pressure across three different occasions were included. Covariance analysis was used to analyze the relationship of clustering of metabolic disorders with left ventricular mass index levels. Multivariable logistic regression model was used to examine the relationship of clustering of metabolic disorders with LVH.@*Results@#After adjustment for sex, age and blood pressure, LVMI levels were (33.21±1.85) (38.57±1.19) and (43.00±1.63)g/m2.7, respectively, for hypertensive children and adolescents carrying 0, 1 and ≥2 metabolic disorders; LVMI levels increased with the number of metabolic disorders in hypertensive children and adolescents (P<0.01). Compared with the hypertensive children and adolescents without any metabolic disorders, the risk for LVH increased in ones carrying 1 and ≥2 metabolic disorders, the odds ratios and 95% confidence intervals were 2.41(1.11-5.23) and 4.69(2.05-10.74), respectively.@*Conclusion@#The clustering of metabolic disorders was positively correlated with the LVMI levels and risk of LVH in hypertensive children and adolescents. Therefore, to prevent cardiac damage such as LVH in hypertensive children and adolescents, it is important to prevent and control metabolic disorders comprehensively.
ABSTRACT
Objective@#To examine the relationship between clustering of metabolic abnormalities with non-alcoholic fatty liver disease (NAFLD) in hypertensive children and adolescents, and to provide a scientific reference for the prevention and control of NAFLD among children and adolescents.@*Methods@#Data were based on a school-based cross-sectional study conducted from September 2012 to September 2014 in Jinan. A total of 261 hypertensive children and adolescents aged 6 to 17 years were included in this study. Chi-square test was used to analyze the prevalence of NAFLD by numbers of metabolic abnormalities. Multivariable logistic regression model was used to examine the relationship between clustering of metabolic abnormalities and NAFLD in hypertensive children and adolescents after adjustment for potential confounding variables.@*Results@#Among the included 261 hypertensive participants, the prevalence of NAFLD with the number of metabolic abnormalities ≤1, 2 and ≥3 was 5.3%, 25.5% and 36.0%, respectively. After adjustment for sex, age and systolic/diastolic blood pressure, compared with hypertensive children and adolescents carrying ≤1 metabolic disorder, those with two metabolic disorders had 6.51 (95%CI=2.52-16.81) times higher risk for NAFLD, and those with≥3 metabolic disorders had 8.89 (95%CI=3.03-26.06) times higher risk.@*Conclusion@#Clustering of metabolic abnormalities is an independent risk factor for NAFLD in hypertensive youth. Comprehensive prevention and control of metabolic disorders in childhood may be helpful to prevent NAFLD.
ABSTRACT
This paper is to explore changes of intestinal mucosal barrier, intestinal flora, and bacterial translocation in rats with severe acute pancreatitis (SAP). Twenty four male SD rats were randomly divided into the control group (n = 10) and the experimental group (n = 14). The model of severe acute pancreatitis of rats was induced by the method of injecting adversely 5% sodium taurocholate into the common biliary-pancreatic duct. All of the rats were killed after 24 hours and the level of the serum amylase and the plasma endotoxin was determined after that. The pathological changes of pancreas and small intestine were observed through hematoxylin-eosin staining (HE staining) and the abdominal viscera bacterial translocation rates were tested. With the method of real-time polymerase chain reaction (RT-PCR) the quantity of the intestinal flora was analyzed. In the control group, the level of Escherichia coli, Lactobacillus and Bifidobacterium were 2.08 ± 1.29, 11.04 ± 7.55 and 12.21 ± 4.95, respectively. On the contrast, the level of Escherichia coli in the cecum contents was much higher (9.72 ± 3.58, P < 0.01), while the Lactobacillus number was decreased significantly (0.67 ± 0.34, P < 0.01), and the Bifidobacterium number was also decreased (4.59 ± 3.42, P < 0.05) in the experimental group, so the ratio of Bifidobacterium/Escherichia coli was reversed. Besides, in the experimental group, the plasma endotoxin positive rates and the bacterial translocation rates were much higher (P < 0.01 or P < 0.05) and the pathology scores of pancreas and small intestines were also significantly higher (P < 0.01) than those in the control group. These results indicated that in severe acute pancreatitis rats, the intestinal mucosal barrier was severely damaged and the dysbacteriosis occurs in the intestinal canal. And these might relate to the occurrence and development of multiple organ infection.

Objective To evaluate Janus kinase (JAKs) and Suppressors of cytokine signaling(SOCSs) expression in myocardium after endurance training. Methods 30 male Sprague-Dawley rats undertook 10 weeks grade treadmill training program and were sacrificed at 0 and 24 h respectively after the last exercise. JAK1,JAK2,JAK3 and SOCS1 ,SOCS2,SOCS6 expression in the myocardium were determined by im munohistochemistry method. Results The percentage of JAK1 positive cell significantly increased immediately after last running and recovered to the sedentary level 24 hrs after exercise;The percentage of JAK2 positive cell significantly increased immediately after last running and continuously at a higher level 24 hrs after exercise (P0.05). The percentage of SOCS1 and SOCS2 positive cell also significantly increased both immediately and 24 hrs after exercise (P0.05). Conclusion Endurance training could induce different responses of JAK1,JAK2 and JAK3. The increased expressions of JAK1 and JAK2 might indicate the changes of JAK/STAT signal pathway in regulating myocardial function. The increased expressions of SOCS1 and SOCS2 after endurance training might indicate the increased exertion in regulating JAK/STAT signal pathway in cardiac muscle.
