Objective To test the utility of a new type of inflatable rehabilitation boot in the treatment of Danis-Weber type-A stable external malleolus fractures. Methods Fifty-four patients with stable external malleolus fractures were randomized into two groups. After closed reduction, the observation group was treated by immobilisation with the inflatable rehabilitation boot and the control group with a plaster slab. All were instructed to avoid weight-bearing on the affected side. The swelling volume of the injured limb was measured by drainage measurement before treatment and at the 1st, 3rd and 7th days after treatment. Pain was evaluated using a visual analogue scale (VAS) score before treatment and after 12, 24 and 72 hours. All of the ankles were x-rayed to recheck for displacement after 2weeks. Results The average volume of the injured limbs in the observation group was significantly less than in the control group at every time point. The average VAS score in the observation group was significantly lower than that in the control group. Fracture displacement in the observation group was also significantly better. Conclusions The inflatable rehabilitation boot has better curative efficacy than the typical plaster slab for patients with stable external malleolus fractures in terms of improving edema in the injured limb, relieving pain and preventing fracture displacement.

Objective Selected the characteristic index of cervical CT tablets, and established stepwise regression equation, to explore the value of its application in forensic medicine identification. Method Each one cervical CT images of 130 cases were collected, 70 subjects were examined for 2 cervical CT images of each. Selected and measured 13 indicators of cervical CT iflms, the difference between the groups was calculated by the same measurement indicators after the random grouping of the inspectors, and the difference between the different measurement indexes of the same person. Using two classification logistic Stepwise regression analysis, establish the regression equation of the index and multiple regression equation of multinomial index, and the test of the equation was carried on blind test. Results Accuracy of 13 equations of the established element is 69.0%~90.4%,accuracy of 4 multiple regression equation is 90.4%~96.7%, blind accuracy rate is 100%. Conclusion 13 feature indicators selected from CT tablets can be used for the same identiifcation, in practice researchers should use multivariate index to get more accurate result.

Objective To explore the application effect of the wechat public platform in follow-up management of patients with moderate or severe craniocerebral injury.Methods 98 patients admitted in the craniocerebral department of our hospital from February to November 2014 were selected and divided into two groups by random number table method,with 48 cases in the control group and 50 cases in the observation group;the traditional follow-up management mode using telephone was adopted to patients in the control group,while the follow-up management mode using the wechat public platform was adopted to those in the observation group,with a follow-up period of 3 months;for patients in both groups,their activities of daily living (ADL) and exercise of self-care agency (ESCA) abilities before and after intervention,occurrence of adverse events and complications within the follow-up period,and their degree of satisfaction towards the follow-up management were collected.Results After intervention,ADL score,total scores of ESCA and total scores of satisfaction towards the follow-up management among patients in the observation group were 87.34±15.26,24.36±17.24 and 86.07±14.82,which were significantly higher than that among patients in the control group were 66.72±14.62,99.37±15.29 and 61.14±13.19 (t=7.941,7.982,6.962,all P ＜0.01);within intervention,the observation group had significantly lower total occurrence rate of adverse events and complications which was16.00％ (8/50) compared to the control group 39.58％ (19/48) (x2=6.824,P ＜ 0.01).Conclusions By establishing the follow-up management mode for patients with craniocrerbral injury through the wechat public platform,effect of the follow-up management can be effectively promoted,prognosis of patients can be improved and patients' degree of satisfaction can be enhanced;it is worth of being further promoted clinically.

Objective:To study the changes of iNOS expression in periodontal tissues of rats with periodontitis in orthodontic tooth movement. Methods:48 SD rats at 10 weeks were divided randomly into two groups: periodontitis teeth group and normal teeth group. The maxillary first molar was pulled mesially both in the two groups. 4 rats were executed each time after activation of pull-spring 1, 2, 3, 7,14 and 21d both in two groups. iNOS immunohistochemistry staining were done to compare the expression variations. Results: There were significant differences between the two groups in 2,3, 7, 14 and 21 d. The periodontitis teeth group had stronger positive signals. Conclusion: Periodontitis will increase the expression of iNOS in the rats periodontal tissue during tooth movement, and influence the reconstruction of periodontium.

Objective To evaluate the efficiency of injection of colloidal chromic phosphate 32 P cavity in rats with rheumatoid arthritis.Methods Collagen induced arthritis (CIA) was produced in Sprague Dawley rats.After one week immune,the right post ankle was given colloidal chromic phosphate 32 P intra articular injection.Severity of arthritis was observed by the left to right diameter of the right post ankle joint,the volume of right post paw and the arthritic index.Results The group treated with colloidal chromic phosphate 32 P intra articular injection developed milder arthritis compared with control CIA group after 6 weeks.The left to right diameter of the right post ankle joint was (3 96?0 05) mm of the colloidal chromic phosphate 32 P intra articular treated group compared with (4 11?0 08) mm of the control CIA group ( P

Advanced in medical and surgical management have led to reduce mortality in children with congenital heart disease(CHD).However,more recent and ongoing research had been focused on neurodevelopmental outcome.With the improved survival in children follo-wing surgery for cardiac malformations,increased emphasis had being placed on neurological sequelae,especially on cognitive function.Car-diac surgery couldn't correct cognitive disorder,more and more findings suggested that the cognitive disorder of CHD might be the result of utero injury.J Appl Clin Pediatr,2009,24(1):61-64

Aim: To study the distribution and excretion of baicalein and baicalin in rats. Methods: An LC/MS method was applied. Chromatographic separation was performed on a C_(18) column( 150 mm ×6.0 mm, 5 μm) with methanol-10 mmol/L ammonium acetate (containing 0. 5% formic acid) as the mobile phase. A trip-quadrupole tandem mass spectrometer was set in positive selected reaction monitoring mode. The sample was extracted with methanol-acetonitrile( 1:1) after the addition of phosphoric buffer solution and luteolin, which acted as the internal standard. The supernatant was evaporated to dryness, and the residual was reconstituted with mobile phase and analyzed. Results: The distribution profiles of the parent drug and its main metabolite showed two peaks between 20-40 min and 8-10 h after oral administration of baicalein, which fit the plasma concentration-time profile of baicalein in rats. At 20 min after the dosing, the concentration levels of baicalein were significantly higher than those of baicalin in stomach, liver and intestines, the converse result occurred in kidney. The excretion results showed that baicalin was the predominant excretion form in bile and urine, while baicalein was the negligible excretion form. There was more baicalein than baicalin in rat feces. Conclusion: Baicalein was absorbed and distributed quickly to various tissues and easily transformed to its metabolite at the same time.
