OBJECTIVETo compare clinical effects between percutaneous compressing plating (PCCP) and proximal femoral nail antirotation (PFNA) for the treatment of patients with intertrochanteric fracture with risk external wall.
METHODSFrom September 2007 to June 2010, 43 patients with intertrochanteric fracture with risk external wall were treated by PCCP or PFNA according to different kinds of internal fixations. There were 22 cases in PCCP, including 9 males and 13 females with an average age of 68.4 (ranged, 60 to 86) years old, and 13 cases with type A2.2 and 9 cases with type A2.3; while 21 cases in PFNA, including 7 males and 14 females with an average age of 67.7 (ranged, 57 to 93) years old, and 10 cases with type A2.2 and 11 cases with type A2.3. Blood loss, operation time, hospital stay, fracture healing time, complications and Harris score after 1 years' following-up were observed and compared.
RESULTSAll patients were followed up for 12 to 22 (means 18.4) months, and all patients were obtained fracture healing, and recovered walking ability as before injury. There were no significant differences in blood loss, operation time, hospital stay, fracture healing time, complications and Harris score after 1 years' following-up (P>0.05). One case occurred displacement on the top of greater trochanter, and 1 case injuried weakness of hip abduction. One case occurred screw breakage in PCCP, while 1 case occurred hip joint pain in PFNA.
CONCLUSIONBoth of PCCP and PFNA in treating patients with intertrochanteric fracture with risk external wall can receive good clinical effects, while the effects and therapy strategy for displacement of bone on the top of lateral wall should further study.

Objective:To'synthesize BODIPY-FL-labeled phenylephrine(BODIPY-FL-PE)and deter-mine its biological activity.Methods:Condensation of BODIPY-FL(green fluorescence dye)and phe-nylephrine(?_1-adrenoceptor agonist)was performed by adding dicyclohexylcarbodiimide(DCC)in thepresence of absolute tetrahydrofuran(THF).The reaction occurred in absolutely oxygen and water condi-tion at room temperature.The crude product was separated and purified by thin-layer chromatography(TLC).The structure of BODIPY-FL-PE was characterized by TLC and mass spectrometry(MS).Itspharmabiological activity was determined by Western blot.Results:BODIPY-FL-PE,the target mole-cule,was synthesized and its structure was identified by using ultra-violet spectrometry(UV)and MS.The result of Western blot indicated that ?_1-adrenoceptor(?_1-AR)induced ERK phosphorylation wasconfirmed in both BODIPY-FL-PE and PE treated groups.Conclusion:The synthesized BODIPY-FL-PEhas pharmacological activity that could activate ?_1-AR.Visualization of AR behaviors could be achievedby tracing the trajectories of BODIPY-FL-PE labeled AR.It might be a promising tool for investigatingdynamic behaviors of AR in living cells.

Objective:To evaluate the clinical efficacy of SKy bone expander system in percutaneous kyphoplasty for treat- ment of osteoporotie verterbral compression fracture.Methods:Twenty-two patients(aged 62-90 years,32 vertebrae)under- went percutaneous kyphoplasty using SKy bone expander system.The bone cement was injected into the collapsed vertebrae. The vasual analogue scale(VAS)and complications were recorded during follow up.Results:The operations were successful in all patients via unilateral or bilateral approach.The operation time ranged from 30 to 120 min.The mean volume of cement in- jected into each vertebra body was(4.8?1.1)ml,ranged from 3.1 to 6.8 ml.Extravertebral leakage of bone cement was ob- served in two vertebrae with no symptoms.All patients had their pain relieved;the VAS was 7.6?0.8 before operation,3.5?0.5 one day after operation,2.8?0.6 one week after operation,and 2.4?0.6 one month after operation,with significant difference found between preoperation and postoperation(P

Background Sirius system,a new Scheimpflug camera combined with Placido topography,improved the capability of imaging the anterior eye segment significantly.However,the study of assessing the repeatability and agreement between Sirius and Pentacam is still lack up to now.Objective This study was to evaluate the repeatability and agreement of the anterior ocular segment measuring parameters by Sirius and Pentacam in myopia received laser in situ keratomileusis (LASIK).Methods Thirty-five myopic eyes of 35 patients received LASIK were included in School of Optometry and Ophthalmology Eye Hospital from 2010 May through 2010 July.Corneal power flat keratometry (Kf),step keratometry (Ks),mean keratometry (Km),thinnest corneal thickness(TCT),the location of TCT,anterior chamber depth (ACD) and anterior chamber volume (ACV) were measured by Sirius and Pentacam in all the eyes,respectively.The repeatability of the measuring results were evaluated using intraclass correlation coefficients (ICC) and Cronbach's coefficient alpha (CoA),and the agreement of measuring parameters between Sirius and Pentacam was analyzed using Bland-Altman plot.Results Both Sirius and Pentacam demonstrated high intraobserver repeatability,with all ICC and CoA more than 0.90.No significant differences were found in Kf values and Ks values between the two methods (t =-1.533,-1.750,P>0.05).Km value was (39.14 ± 1.95) D by Sirius measurement,which was sígnificantly higher than (39.05 ± 1.91) D by Pentacam measurement (t =3.572,P =0.001).The TCT was (457.6 ± 40.9) μm by Sirius method,showing a significant reduce in comparison with (465.4±37.5) μm of Pentacam method (t =-6.689,P<0.001).A positive correlation was seen in the TCT between the two methods (r=0.988,P<0.001).The Bland-Alrman plots showed the 95% CI-21 μm to 6 pm in the TCT value between the two devices.Pairwise comparison of the location of TCT measurements showed significant differences between the two devices (t =-4.132,-5.696,P<0.001),with a good correlation (r=0.751,0.775) and the 95% CI (-0.36-0.17 mm,-0.35-0.12 mm).A very good agreement was seen in ACD between the two devices (-0.02-0.12 mm),but the agreement result was not very well in the ACV between the two devices with the 95% CI (-27.70-6.20 mm3).Conclusions Sirius and Pentacam measurements for anterior ocular segment parameters have a very good repeatability in post-LASIK eyes.In addition,good agreement results are exhibited in corneal power,TCT and ACD between Sirius and Pentacam with an acceptable maximal different value between them.Sirius and Pentacam can be used interchangeably in clinical examination.However,the two devices can not interchangeably for ACV measurement and TCT location.
