Objective:To investigate influences of bicortical anchora ge on the values of natural frequency of dental implants. Methods: Using the commercial code of SolidWorks, 3-D models of a screw-shaped dental i mplant and a mandibular bone segment were generated. After the 3-D implant-bon e complex was meshed by ABAQUS software, effects of bicortical anchorage on the buccolingual and axial first-order natural frequencies of the implant were comp uted. Results:Bicortical anchorage increased the buccolingual na tural frequencies and the axial natural frequencies of the implants by a maximu m of 13.77% and 107.40% respectively. The apical anchorage depth in the cortical bone had an insignificant effect on further increase of implant stability. Conclusion:Bicortical anchorage can increase the stability of dental implants, especially in the axial direction.

Objective To discuss the effectiveness of anterolateral thigh propeller flaps for treatment of inguinal skin and soft tissue defects.Methods From June,2009 to October,2014,12 patients with inguinal skin and soft tissue defects were treated with anterolateral thigh propeller flaps pedicled with perforator of descending branch of lateral circumflex femoral artery.Of them there were 8 males and 4 females,aged from 22 to 51 years.The left side was involved in 3 cases and right side 9 cases.Defects were caused by traffic accident injury in 5 cases,crash injury of heavy object in 7 cases.There were mere skin and soft tissue in 2 cases,combined with bone fractures,nerves,vessels and muscles injury in 10 cases.The area of defects ranged from 9.0 cm×5.0 cm to 22.0 cm×9.0 cm.During operation,anterolateral thigh propeller flaps ranging from 11.0 cm×7.0 cm to 24.0 cm×1 1.0 cm were used to repair the wounds.Results All flaps and skingrafts survived after operation and the wounds obtained primary healing.After 8-24 months follow-up,all flaps were characterized by soft texture,good color,and satisfactory appearance.According to the Britain's Medical Research Council at 8 months after operation,the sensation of the flaps were recovered to S2 ～ S3+,No obvious scar contracture and chromatosis were observed at donor site.Conclusion Anterolateral thigh propeller flaps pedicled with artery descending branch of lateral circumflex femoral perforator is an ideal choice for the reconstruction for inguinal skin and soft tissue defects.

AIM: To investigate the effects of exogenous L - carnitine on lipid metabolism in semi - starved rats fed on high fat diet. METHODS: The semi - starved rats were restricted half in calorie intake on high fat diet for 2 week. L - carnitine was supplied at dose of 250 mg/kg· bw. The changes of plasma carnitine concentration, urinary excretion of ketone body, serum lipase activity, muscle carnitine palmitoyl transferase activity, triglyceride secretion and clearance rate were measured. RESULTS: The results showed that the concentration of plasma free camitine increased significantly in carnitine supplemented rats compared to normal and semi - starved rats. The activities of muscle carnitine palmitoyhransferase and serum lipase were significantly enhanced in carnitine supplemented rats. The triglyceride secretion rate (TGSR) was also improved remarkably by carnitine supplementation. Meanwhile, the urinary excretion of ketone body was reduced significantly in carnitine supplemented rats compared to semi - starved rats. CONCLUSION: It is concluded that carnitine supplementation can significantly increase the plasma concentration of free carnitine and accelerate the lipid metabolism in semi - starved rats fed on high fat diet.

Objective To analysis the changes of heart function in early stage after lung transplantation,and to explore its relationship with decreased pulmonary artery pressure.MethodsFrom 2002 to 2010,echocardiography results of 90 patients before and after lung transplantation in Wuxi People's Hospital were collected, 20caseshadcompletedateofpreoperativeandpostoperative echocardiography.Echocardiographic changes had been analyzed.Pearson linear correlation analysis was applied to determine the relationship between the early postoperative changes in cardiac structure and function and decreased pulmonary artery systolic pressure.ResultsPostoperative pulmonary artery systolic pressure ([38.30 ± 8.92]mm Hg) compared with preoperative([60.05 ± 29.10]mm Hg) was significantly lower(t =3.120, P = 0.006) , Postoperative right ventricular diameter was significantly reduced compared with the preoperative(t = 36.000, P = 0.008) , tricuspid and pulmonary valve regurgitation significantly reduced (t =57.000 and 66, Ps ＜ 0.05) .Postoperative left atrial diameter and left ventricular end diastolic diameter ([35.15± 5.73]mm and [43.25 ± 5.56]mm) compared with preoperative([32.40 ± 7.29]mm and [40.15 ± 6.20]mm)were significantly expanded (t =-2.384 and t =-2.153, Ps ＜ 0.05) .Although postoperative stroke volume ([59.54 ± 14.97]ml)compared with preoperative ([44.18 ± 15.85]ml)significantly increased (t =-3.918, P = 0.004) , but the postoperative left ventricular ejection fraction ([63.10 ± 8.48]％)compared with preoperative ([71.75 ± 8.10]％)was significantly decreased (t =3.742, P = 0.001) .Pearson linear correlation analysis showed the greater degree of decreased systolic pulmonary artery pressure after lung transplantation, the larger rate of increased postoperative left atrial diameter and left ventricular end diastolic diameter, and the bigger range of decreased postoperative LVEF (r = 0.642,0.737 and 0.448, P ＜ 0.05) .ConclusionIn early stage after lung transplant, right heart structure was normalization, right heart function improved,left heart enlarged, stroke volume increased, but left ventricular function reduced.There were a linear correlation between those changes and reduced systolic pulmonary artery pressure.

Objective To explore the effects of group sand play on the behavior of cerebral palsy (CP)children with behavioral problems.Methods Ninety children with CP aged 3-5 with behavioral problems were selected,after those with mental retardation had been excluded through the Peabody picture vocabulary test (PPVT).Their behavioral problems were diagnosed using Achenhach's child behavior check list (CRCL).The children were randomly divided into an experimental group and a control group with 45 cases in each.The experimental group received 10 weeks of sand play treatment in addition to routine rehabilitation.The controls received only routine rehabilitation.Results After treatment,the social withdrawal,depression,aggression and disruptive behavior scores of the 3-year olds in the experimental group were significantly lower than before treatment and significantly lower than those of the controls.For the 4 and 5 year-old boys the results were similar in terms of soclal withdrawal,depression,immaturity,sexual behavior,aggression and delinquent behavior,For the 4 and 5 year-old girls the scores for depression,somatic complaints,social withdrawal,compulsion,aggression,and hyperauctivity showed similar significant improvements.Conclusion Group sand play can improve the behavior and promote the mental health of CP children.
