Objective To explore the effect of preventing adhesion after the orbital blowout fracture on orbit tissue by amniotic membrane. Design Experimental study. Participants Twenty-six New Zealand rabbits. Methods Establishing rabbit orbital blowout fracture model, the right orbit of twenty rabbits was repaired by hydroxyapatite (HA) parceled of amniotic membrane, and left orbit was only repaired by HA, the orbits of the other six rabbits weren't repaired. Then we got the tissue around bone after one week and one month, and compared the difference of three groups. Main Outcome Measures Inflammatory response of tissue around bone was ana- lyzed by HE, picric acid Sirius Scarlet dying, TGF-?immunohistoehemical observation. Results One week after operation, HE and im- munohistochemistry showed that the difference was not significant in inflammatory response between experimental group and control group (P=0.351, P=0.413), and difference is significant between blank group and experimental group (P=0.012, P=0.041). One month after operation, HE and immunohistoehemistry showed that the difference was significant in inflammatory response between experimental group and control group(P=0.037, P=0.048), and there is no significant difference between experimental group and blank group(P=0.285, P=0.472). Conclusion It has an important role of anti-inflammatory and anti-adhesion in the chronic stage of inflammatory after orbital blowout fracture repaired by man-made plates of amniotie membrane.

BACKGROUND:Skul repair materials cannot only restore the normal shape of the skul , but also play an important role in brain functional recovery. OBJECTIVE:To summarize the research status of polyetheretherketone (PEEK), titanium al oy and tissue engineering technique in cranioplasty and the prospect of three-dimensional (3D) printing technology. METHODS:Literatures related to skul repair materials were retrieved in databases of CNKI and PubMed published from 1995 to 2016, using the keywords of“bone regeneration material in calvarial, 3d printing bone scaffold”in Chinese and English, respectively. RESULTS AND CONCLUSION:Although titanium and PEEK have been used in clinic, titanium holds conductivity, thermal conductivity, while PEEK that may be displaced or lost is not involved in osseointegration. Tissue engineering technology participates in the skul tissue reconstruction, achieving satisfactory repair outcomes, but the problems of scaffold selection and preparation, seed cel obtainment, and growth factor release need to be overcomed. 3D printing technology can print personalized shape, fit the defect precisely, but the raw materials should have good biocompatibility and biomechanical property. Combination of tissue engineering technology with 3D printing technology shows a broad prospect in cranioplasty.

Objective To investigate the rates of depression and its risk factors in elderly hypertensive patients and healthy residents in Fuzhou.Methods 882 elderly primary hypertensive patients aged 60 years and over and 1230 healthy elderly residents were assessed by the geriatric depression scale (GDS) and a self-made general information questionnaire, and SPSS 16.0 was used to analyze data.Results The average score of depression and the incidence of depression were higher in elderly hypertensive patients than in healthy elderly residents [(12.43±5.01) vs.(11.53±5.13), 64.4％ vs.55.3％, t=-3.849, x2=16.386, P＜0.01].Compared with healthy controls, scores of depression were higher for all age groups in elderly married male patients, with low levels of education (junior middle school or below), a monthly income less than 2000 yuan, and partial or no medical insurance coverage (P＜ 0.05 for all).Scores of depression were higher in elderly hypertensive patients who had smoking or drinking habits, social activity, hobby, or physical exercise than in healthy controls, (P＜0.05 for all).Scores of depression were also higher in elderly hypertensive patients who had family support, barely enough or adequate family expenses or family support than in healthy controls, regardless of living conditions (P＜0.05 for all).Multiple stepwise regression analysis showed that risk factors for depression in elderly hypertensive patients were family support, age, medical insurance coverage, family expenses, living conditions, hobbies, and gender, while risk factors for depression in healthy elderly residents were family support, interests, medical insurance coverage, and age.Conclusions The incidence of depression is higher in elderly hypertensive patients than in health elderly people in communityin Fuzhou.Family support, hobbies, medical insurance coverage and age are the common risk factors for depression in both elderly hypertensive patients and healthy residents.Family expenses, living conditions and gender are important risk factors for depression in elderly hypertensive patients.
