Objective To observe the display and source of the artery located at anterolateral region next to pancreatic head on en-hanced CT,and to investigate its clinical value.Methods Imaging data of 200 consecutive patients who underwent abdominal CT scan were collected,and their CT images were analyzed.The reconstructed images were obtained at a post-processing workstation. After reconstruction,the display rate,source and branches of the artery located at anterolateral region next to pancreatic head were analyzed,and the diameters of these vessels were measured.Results The arterial vessel located at anterolateral region next to pan-creatic head was found on axial CT image in arterial phase with a display rate of 100%.By using post-reconstruction images,most vessels were gastroduodenal artery with mean diameter of 0.33 cm± 0.05 cm,and other ones were pancreaticoduodenal artery or right gastroomental artery.Conclusion The artery located at anterolateral region next to pancreatic head can be found on axial ab-dominal CT image in the arterial phase.Most vessels are gastroduodenal artery with a fixed position and traveling.

Objective:To explore the changes of bone turnover markers and geometric parameters of hip bone in overweight postmenopausal women with metabolic syndrome(MS), as well as the influence of MS components. To analyze the association of these factors with the risk of fracture.Methods:A total of 505 overweight postmenopausal female patients who underwent health check-up in Lianhu Community Service Center, Danyang City, Jiangsu Province from January to December 2017 were selected. According to the MS diagnostic criteria of the International Diabetes Federation(2009), the patients were divided into MS group( n=331)and non-MS group( n=174). Blood samples were collected to determine the level of procollagen type 1 N-terminal propeptide(P1NP)and carboxy-terminal cross-linked telopeptide of type 1 collagen(CTX). Bone mineral density and hip bone geometry parameters were tested with dual-energy X-ray absorptiometry and hip structural analysis software. Results:The incidence of osteoporotic fracture and hip fracture in MS group was significantly higher than that in non-MS group(21.1% vs 13.8%, 4.8% vs 1. 1%, P<0.05). However, the bone mineral density of lumbar vertebra 1-4, femoral neck, and total hip in MS group was significantly higher than that in non-MS group, which remained after adjusting for age( P<0.05), but the difference disappeared after further adjustment for body mass index( P>0.05). The P1NP, CTX, femur strength index(FSI), section modulus(SM), and cross-sectional area(CSA)of MS group were significantly lower than those of non-MS group, the buckling ration(BR)was significantly higher than that in non-MS group, and the differences were still statistically significant after adjusting for age and body mass index( P<0.05). There was no significant difference in bone mineral density of lumbar vertebra 1-4, femoral neck, total hip, P1NP, and CTX between fracture group and non-fracture group in patients with MS. But FSI, SM, cross-sectional moment of inertia(CSMI), and CSA were significantly lower, BR was significantly higher( P<0.05) and femur strength decreased in patients with fracture. Regression analysis showed that high BR was an independent risk factor for fracture risk, while high FSI, SM, CSMI, and CSA were protective factors. Multivariate linear regression analysis showed that wasit circumference, diastolic blood pressure, and fasting plasma glucose were the main MS components affecting bone mineral density, bone turnover indexes, and hip bone geometry parameters. Conclusions:Overweight postmenopausal MS patients had decreased bone turnover rate, femoral strength, and relatively poor bone quality. Hip bone geometry parameters can be used as one of the methods to assess fracture risk in MS patients. Waist circumference, diastolic blood pressure, and fasting blood glucose are the important MS components affecting bone mass and bone quality.

Objective:To explore the risk of hip fracture, changes of composite indices of femoral neck strength and its influential factors in non-low-weight postmenopausal women with type 2 diabetes mellitus(T2DM).Methods:A total of 626 non-low-weight postmenopausal women were selected and divided into type 2 diabetes group, pre-diabetic group, and non-diabetic group according to the diagnostic criteria of the American Diabetes Association in 2010. Each participant completed the questionnaire, physical examination, laboratory examination, and Dual-energy X-ray absorptiometry(DXA) examination.Results:Hip fracture rate in T2DM group was significantly higher than that in non-diabetic group(3.4% vs 0.7%, P<0.05), while no significant difference was observed between pre-diabetic group and non-diabetic group(1.1% vs 0.7%, P>0.05). Bone mineral density(BMD) of lumbar spine 1-4, femoral neck, and total hip was comparable between T2DM group and non-diabetic group or pre-diabetic group and non-diabetic group, respectively( P>0.05). The composite indices of femoral neck strength in T2DM group was significantly lower than that in non-diabetic group( P<0.05), but there was no significant difference between pre-diabetic group and non-diabetic group( P>0.05). Regression analysis showed that age and body mass index were the main influential factors of the femoral neck bone mineral density and the composite indices of femoral neck strength( P<0.05). Conclusion:The composite indices of femoral neck strength could be used as one of the markers to evaluate the risk of hip fracture in type 2 diabetic patients.

Objective:To investigate the correlation between fat distribution and the composite indices of femoral neck strength in obese postmenopausal women.Methods:A total of 293 postmenopausal women with non-low body weight were selected, laboratory tests, body composition analyzer test and double-energy X-ray absorptiometry scan were performed. Based on the body mass index(BMI), they were divided into three groups, the normal BMI group(18.5 kg/m 2≤BMI<24.0 kg/m 2, n=91), the overweight group(24.0 kg/m 2≤BMI<28.0 kg/m 2, n=115), and the obese group(BMI≥28.0 kg/m 2, n=87). The measurement results were analyzed. Results:In the obese group, bone mineral density(BMD) of all sites was higher than that in the normal BMI group and overweight group( P<0.005), compression strength index(CSI), bending strength index(BSI), and impact strength index(ISI) were significantly lower than those in the normal BMI group( P<0.001, P=0.008, P=0.001). In the obese group, waist circumference, waist-hip ratio, total fat mass, appendicular fat mass, and trunk fat mass were risk factors for CSI, BSI and ISI independent of age, fasting blood glucose, and BMI( P<0.05). Visceral fat grade and Chinese visceral adiposity fat index were the risk factors for CSI, BSI, and ISI( P<0.05). Conclusion:The composite indices of femoral neck strength decreased in obese postmenopausal women, and both subcutaneous fat and visceral fat were negatively associated with the composite indices of femoral neck strength.
