Objective:To establish an atomic absorption spectrometry method for the determination of lead and ferrum in pre-mix-ture coating film. Methods:The samples were digested by microwave digestion system, and Pb was determined by graphite atomic ab-sorption spectrometry(GFAAS), and Fe was determined by flame atomic absorption spectrometry(FAAS). Results: There was good linear relationship within the range of 1.0-5.0 μg·L-1(r=0.999 4) for lead and 0.1-1.0 mg·L-1(r=0.998 4) for ferrum. The recovery of lead was 91. 3%(RSD=1. 4%,n=9)and that of ferrum was 89. 9%(RSD=3. 5%,n=9). Conclusion: The method is accurate and stable, which can be used for the determination of lead and ferrum in pre-mixture coating film

Incidence of ankle fractures is relatively high.Malunited ankle fractures result from inappropriate nonoperative treatment and incorrect surgery as well.It is not difficult to diagnose a malunited ankle fracture when taking history,symptoms and imaging examinations into consideration.Orthopaedic surgeons used to do ankle fusion for this kind of patients as the effect of reconstructive surgery is not clear.This article summarizes the diagnostic and therapeutic methods for ankle fracture malunion based on the articles from 1976 to 2015.More detailed therapeutic methods for deformities involving lateral malleolus,tibiofibular syndesmosis,medial malleolus and posterior malleolus are also reviewed.

Objective:To research the efficacy and safety of fluticasone propionate spray for allergic rhinitis children suffering with adenoidal hypertrophy. Methods:Totally 160 allergic rhinitis with adenoids growth children were in the observation group, in which 109 cases were diagnosed as adenoidal hypertrophy. Totally 157 adenoids growth children were in the control group, in which 114 cases were diagnosed as adenoidal hypertrophy. The two groups both received fluticasone propionate spray treatment for 3 months, and then the nasal endoscopic adenoidectomy volume, symptom score and adverse reactions were observed and analyzed. Results:Allergic rhi-nitis children suffering with adenoidal hypertrophy were mainly in the 3-6-year-old children. After the treatment, adenoids was shrinked in 88 patients (80. 73%) in the observation group, which was significantly higher than that in the control group [67(58. 77%), P<0. 01]. Adenoidal hypertrophy was still in 44 patients (35. 03%) of the observation group after the treatment, which was lower than that of the control group [55(68. 13%), P <0. 05]. In addition, the integral differences of nasal congestion, snoring and mouth breathing in the observation group after the treatment were higher than those in the control group, and the differences were statistically significant (P<0. 05). Conclusion:The efficacy of fluticasone propionate spray used in allergic rhinitis children suffering with adenoi-dal hypertrophy is more obvious than that in adenoid hypertrophy children, which can more significantly improve the symptoms of nasal congestion, snoring and mouth breathing.

To study the characteristics of pharmacological effects of property combinations of traditional Chinese medicines (TCMs) distributing in the stomach meridian based on medicinal property combination, in order to further define the association relationship between properties of TCMs and their pharmacological effects, and build a bridge for the interpenetration and combination between the medicinal property theory of TCMs and their pharmacological effects. On the basis of the studies on the medicinal property theory of TCMs distributing along the kidney meridian and their pharmacological effects, efforts were made to collect relevant data for medicinal properties and pharmacological effects and mine the characteristics of pharmacological effects that were corresponding to relevant medicinal property combination by processing materials related to medicinal properties and pharmacological effects with the association rules method. According to the analysis, TCMs distributing along the kidney meridian with different medicinal property combinations were significantly differentiated in the pharmacological effects, but shared identical pharmacological effects, such as immunological enhancement. In this study, TCMs distributing along the kidney meridian with different medicinal property combinations were taken as the carriers to closely integrate the traditional Chinese medicine theory with the modem study achievements, lay a solid foundation for further developing and enriching the traditional Chinese medical property theory, while providing a new perspective on the development of modem medicine.

Objective To explore the influencing factors of disabled elderly caregivers' resilience,and to provide evidence for further intervention studies.Method Totally 221 caregivers in several communities were investigated with self-design general questionnaire,Activity of Daily Living Scale (ADL),ConnerDavidson Resilience Scale(CD-RISC) Chinese version,Simplified Coping Style Questionnaire(SCSQ),General Self-Efficacy Scale(GSES) and Perceived Social Support Scale (PSSS).Results The caregivers' resilience score was 59.99 ± 15.86,at a medium level and lower compared with normal population (t =-5.07,P＜0.01).It was positively correlated with the positive coping(r=0.468,P＜0.01),general self-efficacy (r=0.546,P＜0.01)and perceived (r=0.372,P＜0.01).Multiple stepwise regression analysis showed the positive coping,self-efficacy and social support of caregivers were influencing factors of caregivers' resilience (P＜0.01).Conclusion Disabled elderly caregivers' resilience is lower than the general population,and implementation of the intervention should be taken according to different resilience levels at clinical practice.

BACKGROUND:Platelet rich plasma contains various growth factors, such as platelet-derived growth factor, metastatic growth factor, insulin-like growth factor, epidermal growth factor as wel as vascular endothelial growth factor. Therefore, it can directly or indirectly promote cel differentiation and proliferation in different stages of bone regeneration.
OBJECTIVE:To study the effects of coral bone with platelet rich plasma in the repair of mandibular defects.
METHODS: Totaly 24 New Zealand white rabbits were randomly divided into three groups (n=8 per group) including test group, control group and blank control group. Coral bone with autologous platelet rich plasma, coral bone or nothing was implanted, respectively, after establishing unilateral mandibular defect models. The defects were evaluated by imaging observation and bone his-tomorphometric analysis at 2, 4, 8, 12 weeks after surgery.
RESULTS AND CONCLUSION:At 12 weeks after surgery, by imaging observation, density of the defect increased in the blank control group, which was lower than that of the normal bone; the bone density in the test group was higher than that in the control group, both of which were similar with the normal bone. Besides, the materials were closely combined with the new tissues. By bone his-tomorphometric analysis, area of the new bone in the test group was significantly larger than that in the control and blank control group (P< 0.05). In conclusion, coral bone with platelet rich plasma has good biocompatibility and bone conductivity, which can induce bone regeneration to promote defect repair.
