Objective To observe the effect of pressure-protective brace with pressure-sensitive device in the early stage rehabilitation training enhance bone healing, shorten the treatment course and reduce complications,a kind of independently developed pressure-protective brace with pressure-sensitive device was utilized with quantified discontinuous longitudinal stress stimulation under doctors' regulation according to procedure. Methods The pressure-protective brace with pressure sensitive device for rehabilitation training was developed in May 2008 ,and was applied in clinics during January 2009 to June 2010. Forty elder patients,with complete clinical data, underwent Dynamic Hip Screw (DHS) internal fixation of femoral intertrochanteric fracture were were enrolled into this study. These cases were assigned into experimental group and control group with 20 patients respectively. The patients of experimental group performed lower extremity rehabilitation training wearing the pressure-protective brace. The load training of lower extremities with double crutches was modulated by doctors through regulating the threshold value of pressure in different time and different condition after operation according to the prearranged rehabilitative plan of individuation. The controls were instructed to performed lower extremity rehabilitation training in traditional way. Both the clinical healing and bone union time in all cases were evaluated according to the uniform standard. Results Total 40 patients were followed up for 13.0 - 24. 0 weeks ( average, 17.6 weeks ). Clinical healing time was 7.0 - 12. 0 weeks ( average,9. 1 weeks ) and bone healing time was 12. 0 - 16.0 weeks(average,13. 7 weeks)in experimental group. While in control group,the clinic healing time and bone union time was 9. 0 - 13.0 weeks( average, 11.3 weeks) and 14. 0 -20. 0 weeks (average, 16. 6 weeks)respectively. The Independent T-test results showed that whether clinic healing time or bone healing time presented significant differences between experimental group and the controls( P＜0. 01 ). All of the fractures in these two groups were healed at the end time of follow up without adverse complications,including fracture displacement, implant break, implant loose and failure. Conclusion The pressure-protective brace with pressure sensitive device used for quantifying rehabilitation training can enhance bone union, shorten the treatment course and reduce complications. This method further proves that discontinuous compressive stress in a certain range can stimulate fracture healing.

Objective To compare the efficacy of urinary type Ⅳ collagen( Ⅳ C), N-acetyl-β-D-glucosaminidase( NAG ), serum cystatin C ( CysC ), β2 microglobulin ( β2-MG ) in early diagnosis of diabetic nephropathy(DN) ,and to develop a multiple regression equation using above mentioned indices. Methods One hundred and eight cases of DM patients were enrolled in the study. All those DM patients were divided into two groups according to 24 hr urinary albumin excretion(UAE): non-DN group( UAE ＜30 mg/24 h)and DN group (UAE ≥30 mg/24 h). Receiver operating characteristics (ROC)curve was developed using urinary IVC, NAG,serum CysC and β2-MG,and the efficiency of the four indices for early diagnosis of diabetic nephropathy were assessed by area under the curve ROC (AUCROC). Furthermore, the regression equation of four indicators was developed. All statistical analyses were performed using SPSS 13.0. Results The levels of urine Ⅳ C, NAG,CysC,β2-MG,were(3.91±1.93)ng/ml, ( 12.20 ±3.46)U/L, ( 1.18 ±0.41 )mg/L , (2. 50 ±0. 74)mg/ml in the non-DN group, respectively; and ( 14.14 ± 11.17 ) ng/ml, ( 23.12 ± 13.57 ) U/L, ( 2.69 ± 1.69 ) mg/L and(5.21 ± 2.78)mg/ml in the DN group, respectively. There were significant differences in the comparison of the four indicators between the two groups ( Ps ＜ 0.01 ). AUCROC of Ⅳ C, NAG, CysC and β2-MG were 0. 747,0.732,0.764 and 0.823 respectively;which meant the diagnostic efficacy for DN decended from β2-MG, CysC,Ⅳ C, to NAG in order. All these indices showed significant efficiency in assisting diagnosis of early DN ( Ps ＜0.01 ). The regression equation of UAE and the four indices was: UAE = - 242.624 + 6.362IVC + 8.662NAG + 64. 622CysC + 29.488β2-MG, and the equation had statisticl significance( P ＜ 0.O1 ).
