Fifteen cases of periprosthetic femoral fractures of after total hip arthroplasty (THA) in Department of Orthopedic Surgery, Guangdong People’s Hospital between May 1997 and May 2007 were retrospectively analyzed. According to the classification of Vancouver, there was 1 case of type AG, one of type AL, 3 of type B1, 5 of type B2, 3 of type B2, and 2 of type C. Two cases of type A were treated with conventional method, and cases of type B1 and C were treated with open reduction and internal fixation. Cases of type B2 and B3 were treated with a long-stem cemented prosthesis revision plus allograft cortical strut bone. Through 3-12 months follow-up, all the fractures were healed, and bone allografting was successful, but with high rate of complications which were curable. The new prosthesis stem was fixed well. Excellent and good rate of Harris scores for hip joint was 73.3%. Therapy selection based on Vancouver classification for periprosthetic femoral fracture after total hip arthroplasty is an effective method.

Objective To compare the effect of allograft and autograft of bone-patellar tendon- bone (B-PT-B) under arthroscopy in reconstruction of anterior cruciate ligament (ACL).Methods The injured ACL was reconstructed under arthroscopy by using autograft of B-PT-B in 30 cases and al- lograft of B-PT-B in 28 cases from January 2000 to August 2003.After over twelve months follow up,a comparison was done on rehabilitation of quadriceps femoris,knee stability,the Lysholm's score of knee and the enlargement of tunnel in both groups.Results Both groups obtained marked improvement of knee stability and symptoms after operation.But in the early time,the rehabilitation of quadriceps femoris in the ailograft group is faster than that in the autograft group.The rehabilitation of quadriceps femoris, knee stability and the Lysholm's score of knee were similar at 12th month (P>0.05).There could be seen enlargement of tunnel in both groups,with more in the allograft group (P>0.05).Conclusion For arthroscopic reconstruction of anterior crucial ligament (ACL),allograft of B-PT-B is good substitute, for it is characterized by effectiveness,convenience and minor side effect.

A new organic-soluble co-reactant of N,N,N’,N’-tetrakis(propyl)-pentanediamine (TPPD) was synthesized and co-immobilized with tris ( 2, 2’-bipyridine ) ruthenium ditetrakis ( 4-chlorophenyl ) borate ([Ru(bpy)3][4-(Clph)4B]2) on an indium tin oxide (ITO) electrode for electrochemiluminescent (ECL) study. The hydrophobicity of TPPD prevented its leakage from the electrode surface, thus the long-term stability of the ECL electrode was enhanced. The TPPD/[Ru(bpy)3][4-(Clph)4B]2 modified-ITO electrode exhibited strong, stable and reproducible ECL signal. The ECL signal could be quenched efficiently by phenol with a quenching efficiency of 95. 4% in the presence of 0. 1 mmol/L phenol, demonstrating the potential of the modified electrode in determination of phenolic compounds. The transient-state of the electrogenerated chemiluminescence reaction was also investigated, which revealed that the TPPD/[Ru(bpy)3][4-(Clph)4B]2 modified-ITO electrode had a longer lifetime than conventional TPA-Ru(bpy)2+3 co-reactant system.

AIM:To investigate the differences among Lenstar 900, A-scan ultrasound and keratometer in measurement of axial length ( AL ) , anterior chamber depth ( ACD ) and corneal curvature ( K1 , K2 , Km ) , and evaluate the consistency of the instruments, with the purpose providing references for the clinical application of Lenstar 900.
METHODS: In this study we picked up 36 patients ( 50 eyes ) underwent cataract surgery, and lens nucleus hardness were under level IV. Before the operation, AL, ACD and K1 , K2 , Km were measured by Lenstar 900, A-scan ultrasound and keratometer respectively. The differences between the results were compared by the paired t-test. The correlation of the results was analyzed by Pearson correlation analysis, and the consistency was measured by Bland-Ahamn method.
RESULTS: The mean AL and ACD values measured by Lenstar 900 and A-scan ultrasound had no significantly statistic differences (P>0. 05). The K1, K2, Km measured by Lenstar 900 and keratometer were not significantly statistical different (P>0. 05). The results measured by these three instruments had close linearity correlation ( r>0.9, P<0. 01). The consistency of the results was well in Bland-Ahamn analysis.
CONCLUSION:The preoperatively biometric result of Lenstar 900, A - scan ultrasound and keratometer in patients with cataract are all reliable, and they can be substituted by each other. However, Lenstar 900 can not only measure AL, ACD and corneal curvature at the same time, but also cornal thickness, lens thickness, white to white, pupil size, optical axis eccentricity, retinal thickness and so on. It has a number of advantages such as non-touching, convenient and efficient, and can be recommended to use widely.

Objective To evaluate the outcome of unconstrained shoulder arthroplasty for severe injury of proximal part of the humerus.Methods Twelve eases were all treated with unconstrained shoul- der arthroplasty.Six patients with complex fractures of proximal humerus and four with bone tumor in the proximal part of the humerus used hemiarthroplasty and two patients with osteoarthritis were managed with total shoulder arthroplasty.Cemented prostheses were used in all the cases.Results The average age was 65 years and the follow-up was 2.3 years.Two cases of complex fractures had light pain with limited external rotation of the shoulder.No pain or prosthetic stems loosening were found,and the range of motion and the function of the shoulder were satisfactory in other cases.Conclusion Unconstrained shoulder arthroplasty is a satisfactory and safe technique for severe injury of proximal humerus.
