Bone xenograft bone for the treatment of bone defect is one of the current research focus, which has advantages of extensive sources, low cost, simple preparation method. While the process of single bone xenograft bone in repairing bone defect is very long, and the clinical outcome is not satisfactory. The main problems focus on formation of bone and vascularization. Reconstituted bone xenograft combined with cells and xenogenic bone material could promote vascularization and bone fusion in vivo, thus achieve a clinical effect of autogenous bone in repairing bone defect.

Objective To analyze the occurrence of traumatic carotid cavemons fistula (TCCF) resulted from the fracture of basilaris cranii, in order to find out the related factors to outcomes and to discuss the approaches to improving prognosis.Method Data of 312 patients with the fracture of skull base complicatcd with TCCF con-firmed angiography from 1999 to 2005 were analyzed. These patients were classified into patients with disable and patients without disabed. The factors potentially impacting on outcomes were analyzed. Results The overall inci-dence of TCCF in 312 patients with fracture of basilaris cranii was 3.8% .The incideucs of TCCF occurred in pa-tients with the fracture of anterior fossa, middle fossa and posterior fossa accounted for 2.4%, 8.3 % and 1.7 %, respectively. Between two cohorts of patients, there were no difference in age, gender, number of embelization proce-dares performed and the time from injury to appearence of the first symptom except the differencc in time from ap-pearence of the first symptom to the intravascular embohzation performed (P>0.05). Conclusions A relatively high incidence of TCCF occurs in patients with middle fossa fractures, especially those with transverse or oblique fractures. Prompt diagnosis and intervention can not be emphasized in case of patients with TCCF, and non inva-sive techniques for the early detection of TCCF under certain circumstance after brain or facial trauma should be considered so as to avoid a miss in the early diagnosis of middle fossa fracture to ensure favourable outcomes.

Objective:
To investigate the proportion of achieving the blood lipid control target and its influencing factors among residents at a high risk of atherosclerotic cardiovascular disease (ASCVD), so as to provide insights into management of blood lipid among residents at a high risk of ASCVD.
Methods:
Residents at a high risk of ASCVD and at ages of 35 to 70 years were sampled using a multi-stage cluster sampling method from 6 counties (districts) in Shaoxing City from May to July 2021. The residents' demographics, smoking, alcohol consumption and medical history of chronic diseases were collected using questionnaires, the height, weight, waist circumference (WC) and blood pressure were measured, and the total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and fasting blood glucose were detected. The proportion of blood lipids achieving the control target was analyzed, and factors affecting the proportion of blood lipids achieving the control target were identified using a multivariable logistic regression model.
Results:
A total of 1 695 individuals at a high risk of ASCVD were enrolled, including 940 men (55.46%) and 755 women (44.54%), with a mean age of (62.56±6.08) years. There were 285 participants that achieved the target of blood lipid control (16.81%). Multivariable logistic regression analysis identified gender (male, OR=1.962, 95%CI: 1.396-2.758), age (OR=1.037, 95%CI: 1.013-1.061), WC (OR=0.979, 95%CI: 0.964-0.995), diastolic blood pressure (OR=0.981, 95%CI: 0.967-0.994), smoking (OR=1.485, 95%CI: 1.034-2.133), alcohol consumption (OR=0.684, 95%CI: 0.498-0.941), hypertension (OR=1.428, 95%CI: 1.006-2.207), administration of hypoglycemic drugs (OR=2.326, 95%CI: 1.720-3.144) as factors affecting the achievement of the target for blood lipid control among residents at a high risk of ASCVD.
Conclusions
Individuals at a high risk of ASCVD with higher WC, higher diastolic blood pressure and alcohol consumption are less likely to achieve the target for blood lipid control, while male individuals with older age, hypertension and administration of hypogcemic drugs are more likely to achieve the target for blood lipid control.
