Objective To study and summary the treatment of talus fracture. Methods Fifteen patients with talus fracture were treated by limited cut off reduction by leverage and hollow lag screw under C arm X-Ray machine January 2008 to November 2014, of whom there were 11 males and 4 females, aged 15-61 years old. Seven patients sufferred from talus fracture because of traffic accidents, 4 patients because of falls, 2 patients because of crush injury, and 2 patients because of sprains. Hawkins typing:Ⅰtype in 1 patient, Ⅱ type in 6 patients, Ⅲ type in 6 patients of Ⅲ type, and Ⅳ type in 2 patients. Results Followed up for 6 months to 4 years (mean 1.5 years), fracture healed better. Hawkins grading standard:9 patients showed excellent (1 patient ofⅠtype, 5 patients ofⅡtype, 3 patients ofⅢtype), and two patients showed good (Ⅲtype). The excellent and good rate was 11/15. Necrosis of talus occurred in one patient, and degenerative joint disease occured in one patient. Conclusions Minimally invasive internal fixation with hollow lag screw under C arm X-Ray machine in the treatment of talus fracture has a small injury to the periosteum and the blood supply of small soft tissue. It can fix reliably and can pressurize the fracture fragments, and is conducive to fracture healing.

Objective:To investigate clinical significance of the detection of bone mineral density(BMD)and serum levels of vitamin D in elderly patients with Parkinson's disease(PD).Methods:Sixty elderly patients with PD(the PD group)admitted in our hospital from June 2016 to December 2018 were enrolled in this retrospective study.And 60 healthy persons confirmed by annual health check-up matched for age and sex during the same period were included as the control group.PD patients were divided into the osteoporosis group(n=23)and the non-osteoporosis group(n=37). The clinical data, bone mineral density and serum vitamin D level were compared between the two groups.Multivariate Logistic regression method was used to analyze related factors for osteoporosis in PD patients.Results:The incidences of osteoporosis and vitamin D deficiency were higher in PD group than in control group[23 cases(38.3%) vs.13 cases(21.7%)、35 cases(58.3%) vs.21 cases(35.0%), all P<0.05]. Bone mineral density and serum 25-(OH)D level were lower in PD group than in control group[(0.77±0.08)g/m 2vs.(0.83±0.09)g/m 2, (25.65±8.65)nmol/L vs.(39.80±10.74)nmol/L, t=4.381 and 8.439, P<0.05]. The age, course of disease and H-Y grade were higher and serum level of 25-(OH)D was lower in the osteoporosis group than in the control group( P<0.05). Spearman correlation analysis showed that BMD and 25-(OH)D were negatively correlated with age, course of disease and H-Y stage, respectively, and BMD was positively correlated with 25-(OH)D( r=0.396, P<0.05). Multivariate Logistic regression analysis showed that vitamin D deficiency was an independent risk factor for osteoporosis in elderly PD patients( OR=2.332, 95% CI: 1.772-8.224, P<0.01). Conclusions:The incidence of osteoporosis is high in elderly PD patients, and vitamin D deficiency is often present.Vitamin D deficiency may be an independent risk factor for osteoporosis.

This study aims to develop an improved cell screening system for farnesoid X receptor (FXR) agonists based on a dual luciferase reporter gene system. FXR response element (FXRE) fragments from FXR target genes were cloned and inserted into upstream of firefly luciferase (Luc) gene in the plasmid pGL4-luc2P-Hygro. In combination with the internal reference plasmid containing renilla luciferase, a dual luciferase reporter gene system was developed and used for high throughput screening of FXR agonists. After studying the effects of over-expression of RXR, mouse or human FXR, various FXRE fragments, and different ratio of FXR plasmid amount to reporter gene plasmid, induction efficiency of the screening system was optimized by the known FXR agonist GW4064, and Z factor for the system reached 0.83 under optimized conditions. In summary, an improved cell screening system based on double luciferase reporter gene detection system was developed to facilitate the discovery of FXR agonists, where a new enhanced FXRE element was formed by a superposition of multiple FXRE fragments from FXR target genes, instead of a superposition of traditional IR-1 (inverted repeats-1) fragments.
