The present study retrospectively analyzed 8 patients with hip dysplasia (8 hips) comprising 2 males and 6 females, aged 46 years old (range, 35-65 years old) who received treatment at the Department of Orthopedics, Second Affiliated Hospital of Nanchang University between September 2004 and November 2006. Preoperative radiographs and CT examination showed that all patients presented with sharp angle of affected hip > 45°, poor containment of femoral head, narrow joint space, and non-successive Shenton's line. Following Crowe classification, there were 5 cases (5 hips) of grade Ⅱ,and 3 cases (3 hips) of grade Ⅲ. Preoperative Harris hip score was 50 points (range, 44-62 points). Total hip arthroplasty was employed in each patient. Prosthesis was fixed by Cementless or cemented modes. Cementless fixation was applied in 6 hips and cemented fixation in 2 hips. Cementless prosthesis was used on the affected side in each patient. Replacement time, bleeding volume during surgery, hospital days post-surgery, Harris scores, and peri-operative complications were recorded.Simultaneously, post-surgery healing was observed. All 8 cases were followed up for an average period of 6 months. All patients exhibited well recovered joint function. No infection, sciatic nerve injury, dislocation of hip joint, fracture of femoral shaft, thrombosis of deep veins, or prosthesis loosening were found in any follow-up case. Six months after surgery, Harris hip score was 88 points (range, 86-94 points). Radiographs taken at 3 months post-surgery displayed the bone union of surgical region. All these findings suggest that acetabular medial wall displacement osteotomy in total hip arthroplasty produces obvious early- and middle-stage effects in treatment of hip dysplasia.

OBJECTIVE:To establish the quality standard of Compound duzheng tablets. METHODS:TLC method was used for qualitative identification of Vitis davidii,Aralia chinensis,Acanthopanax senticosus and Panax notoginseng in the preparation. The contents of syringoside,oleanolic acid,ginsenoside Rg1,ginsenoside Rb1 and notoginsenoside R1 were determined by HPLC. The determination was performed on Inertsil ODS-SP C18 column with mobile phase consisted of acetonitrile-water(gradient elu-tion)at the flow rate of 1.0 mL/min. The detection wavelength was set at 215 nm,and the column temperature was 25 ℃. The sam-ple size was 10 μL. RESULTS:TLC spots of V. davidii,A. chinensis,A. senticosus and P. notoginseng were clear and well-separat-ed without interference from negative control. The linear ranges of syringoside,oleanolic acid,ginsenoside Rg1,ginsenoside Rb1 and notoginsenoside R1 were 0.056-0.337 μg(r=0.9998),0.022-0.130 μg(r=0.9999),0.030-0.182 μg(r=0.9995),0.010-0.061 μg(r=0.9998),0.038-0.226 μg(r=0.9999),respectively. RSDs of precision,stability and reproducibility tests were all lower than 3.0%. The recoveries were 100.55%-103.80%(RSD=2.0%,n=9),100.00%-104.56%(RSD=3.0%,n=9),97.06%-102.94%(RSD=2.1%,n=9)、97.06%-102.94%(RSD=2.0%,n=9),96.67%-100.00%(RSD=1.5%,n=9). CONCLUSIONS:Established standard can be used for the quality control of Compound duzheng tablets.

OBJECTIVE To evaluate the significance of transnasal endoscopic optic decompression in traumatic optic neuropathy. METHODS Four patients with blindness from traumatic optic neuropathy were treated with transnasal endoscopic optic decompression. RESULTS Two patients improved in visual acuity to CF/50 cm and light perception. Two patients didn’t improve after surgery. CONCLUSION Transnasal endoscopic optic decompression is significant in the management of traumatic optic neuropathy due its effectiveness and minimal invasiveness. It’s implications can be enlarged under some circumstances.
