BACKGROUND:Nasolabial fold flap has been widely used in clinical surgery. The facial artery anatomy has been widely used in clinical research. Angular artery dissection is becoming more and more important to nasolabial groove area surgery, but at present, there is a lack of anatomical analysis of internal angular artery.
OBJECTIVE:To study the anatomy of the angular artery, and to provide anatomical data for protecting the nasolabial flap during surgery.
METHODS:Twenty sides of adult cadaver specimens on head and face were dissected. A reference coordinate system was made based on the line between the connection of two medial angles of eyes (axis X) and the facial midline line (axis Y). The location of the angular artery was measured taking A-F as reference points.
RESULTS AND CONCLUSION:(1) The slant angles of the angular artery on BC section, CD section, DE section and EF section were (11.1±4.3)°, (34.1±8.8)°, (21.5±10.5)°, and (17.0±4.7)°, respectively. (2) The angular artery sourced from facial artery was more than it sourced from ophthalmic artery. The diameter of right blood vessel was larger than that of left side. (3) The angular artery sourced from ophthalmic artery comes from the location which extended 8.1 mm to both sides from the point which was 10 mm up from the intersection of facial medial angle of eyes connection and midline. The blood vessel diameter of the starting point was (0.7±0.2) mm. The whole range was 20.1 mm. (4) The angular artery sourced from facial artery comes from the location which extended 25.8 mm to both sides from the point which was 40 mm down to the intersection of facial medial angle of eyes connection and midline. The blood vessel diameter of the starting point was (0.9±0.3) mm. Point to the wing of nose the lateral distance was (5.0±1.2) mm. The whole range was 68.7 mm. The surface projecting of angular artery coming from research results provided anatomic basis for surgery of nasolabial flap.

Objective To investigate the effects of Danzhi Jiangtang Capsule on CXCL9 and IL-8 in type 2 diabetic model rats, and discuss the mechanism in TCM intervention in type 2 diabetes. Methods Fifty male SD rats were randomly divided into 5 groups:normal control group, high-dosage group of Danzhi Jiangtang Capsule, low-dosage group of Danzhi Jiangtang Capsule, pioglitazone group and model group. Normal control group was fed with basal diet, while the other groups were fed with high fat diet. A single intraperitoneal injection of STZ of 35 mg/kg was employed to establish the animal model of diabetes mellitus. When the diabetic rodent model was built, high-dosage group of Danzhi Jiangtang Capsule and low-dosage group of Danzhi Jiangtang Capsule were treated with 1.08 g/(kg?d) and 0.54 g/(kg?d) by gavage, pioglitazone group was treated with 10 mg/(kg?d) by gavage, the blank group and the model group were treated with physiological saline 5 mL/(kg?d) by gavage for 8 weeks. CXCL9, IL-8 and blood glucose, and lipid in serum of rats were determined with double antibody sandwich method. Results Expressions of CXCL9 and IL-8 in model group increased significantly, compared with the normal control group (P<0.05, P<0.01). Expressions of CXCL9 and IL-8 in high and low dosage Danzhi Jiangtang Capsule group significantly decreased, the blood glucose and lipid also decreased, compared with model group (P<0.01). Conclusion Danzhi Jiangtang Capsule has inhibitory effects on the high expression of inflammatory factors in diabetes, and can also lower bloodglucose, and regulate blood lipid.
