Objective To analyze the normal anatomy and variation of arteries around ankles in Chinese adults in and around Shaanxi province. Methods Aged 18-82 (48±15) years, 522 males and 557 females who came to Xijing Hospital for medical treatment or for a healthy check were randomly recruited to participate in this study. Their arteries around ankles were assessed by high-frequency color Doppler ultrasound. Then the anatomy and variation of the arteries were analyzed. Results There were totally 213 arterial variations in 175 subjects, including variations at single ankle in 137 subjects and variations at both sides in 38 subjects. The rate of arterial variation at ankle in persons was 16.2%(175/1 079) and was higher in females than that in males (21.5%, 120/557,χ2=24.028, P=0.000). The rate of arterial variation at ankle in limbs was 9.9%(213/2 158). There was no signiifcant difference for the rate of arterial variation between the left (5.1%, 109/2 158) and right (4.8%, 104/2 158) ankles (χ2=0.129, P=0.701). In variations of arteries at ankles, there were 131 cases with small posterior tibial arteries and peroneal arteries extending to the bottoms of feet, i.e., posterior tibial arteries substituted by peroneal arteries (typeⅠ, 6.1%, 131/2 158), 69 cases with small anterior tibial arteries and peroneal arteries extending to the dorsums of feet, i.e., anterior tibial arteries substituted by peroneal arteries (typeⅡ, 3.2%, 69/2 158), and 13 cases with both small anterior and posterior tibial arteries, and peroneal arteries extending to both the dorsums and bottoms of feet, i.e., both anterior and posterior tibial arteries substituted by peroneal arteries (typeⅢ, 0.6%, 13/2 158). There was no signiifcant difference in each type of variation rates between left and right sides. The rates of typeⅠvariation were 6.0%(65/1 079) and 6.1%(66/1 079) at the left and right ankles respectively (χ2=0.010, P=0.928);the rates of typeⅡvariation were 3.6%(39/1 079) and 2.8%(30/1 079) at the left and right ankles respectively (χ2=1.213, P=0.271);the rates of typeⅢvariation were 0.5%(5/1 079) and 0.7%(8/1 079) at the left and right ankles respectively (χ2=0.697, P=0.404). Conclusions Ultrasound can be used to depict anatomy and variation arteries around ankles. There is a high prevalence of anatomic variation of ankle arteries in population in and around Shaanxi province. Therefore it will be helpful for diagnosis vascular abnormalities with the knowledge of characteristics of normal anatomy and variation of ankle arteries.

Objective To purify asprosin protein expressed in Escherichia coli expression system and to study its effect on cardiac function.Methods Coding sequence of asprosin was obtained from GenBank.Codon optimization was performed according to the codon preference of E.coli.After gene synthesized, recombinant plasmid was made.Asprosin was then induced and purified by Ni-affinity purification.The mouse model of impaired cardiac function was established by ligating and relaxing the left anterior descending coronary artery.30 mice were randomly divided into 3 groups: sham operation group (sham), cardiac dysfunction group (MI/R) and cardiac dysfunction plus injection of recombinant asposin protein group (MI/R+rAsp).The left ventricular function was detected by echocardiography to determine the improving effect of recombinant asprosin protein on cardiac function.Results After prokaryotic expression and purification, the purity of the target protein was higher than 95%, and the endotoxin content was less than <0.1 EU/μg protein, which was suitable for cell and animal studies.After the recombinant asprosin protein was given, the left ventricular function of the mice was improved significantly (P<0.05).Conclusions Asprosin acts as a myocardial protective molecule to improve cardiac function.

Objective To report our usage of a combined flap which is constituted of bilateral hallux nails, skins, bones to reconstruct a finger, and to introduce the method and outcome of this way. Methods Combine two halves of halluxes harvested from both feet to reform a fabricated finger and then transplant it to the finger stump to reconstruct the defect part of the finger. Plantar flaps or some other flaps near the donor sites were transposed to cover them. From June 2003 to June 2009, a total of 20 fingers (20 cases) which had defect degrees range from I to Ⅲunderwent reconstruction surgeries in this way. Results All the 20 fingers transplanted survived completely. Follow-ups 1 to 5 years after each surgery: all the fabricated fingers had very realistic configurations. The MP joints of the reconstructed thrumbs got to the normal range of motion, and the other reconstructed fingers' total ROM were 203 degree on average. All the reconstructed fingers had the sensation function above S3,and their two-point discriminations ranged from 6mm to 10mm. Both halluxes of each case were conserved major parts of nails and had nice, symmetric appearances. All the flaps for the donor halluxes survived completely, and none of the cases showed pains, ulcers or abrasions of their feet. All the cases showed normal gaits during follow-ups. Conclusion The combined flap by bilateral hallux nails, skins, bones is an ideal alteration for finger defect reconstruction for the important advantages of realistic configuration as well as minor destructions to donor sites.

Objective To study the sectional anatomy of the cardiac septum to provide the reference for clinical imageology and surgery. Methods Sixteen normal adult hearts without organic lesions were verified macroscopically. After vascular perfusion, the specimens were embedded with gel, fixed with 5% formalin, and cryopreserved for a week, and then were sectioned with the Digital Sectioner. Results A total of 1 608 slices (thickness: 0.2 mm) of the heart were obtained. Cardiac septum and the surrounding structures were shown clearly. The demarcation of connective and muscular tissues was clear. The diameters of the cardiac apex, fossa ovalis, brawny intraventricular septum, left ventricle, right ventricle, left and right fibrous trigone were measured with Photoshop6.0. Conclusion The clear images can display tiny structures that could be measured, which could provide anatomical references clinical imageology and surgery.

Objective To analyse the failure reason in transcatheter closure of ventricular septal defect(VSD) ,in order to improve the succeeding rate of occlusive operation on screening VSD patients with echocardiography. Methods Echocardiographic datas were summarized in 50 cases who were failed in VSD occlusion. Results Atrio-ventricular block was occurred in 14 patients,residual shunt was visualized in 13 cases,transcatheter occlusive track could not be set up in 19 cases,arotic valve regurgitation in two cases were screened obviously after occlusive device was released into the intracristal VSD. One case was suffered from cononary heart disease(CAD) and another one was suffered from acute myocardial infarction with ventricular septal perforation. All these patients did not succeed in closure procedure. Conclusions The defect sizes of left and right sides of ventricular septal, structure close to defect must be considered in selecting patients before operation by echocardiography. Occlusion operation should be strictly chosen in cases who were children,or suffered from complex VSD,or senior patients with CAD.
