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.

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.

SuperparamagneticSiO2@Fe3O4microspherewithcore-shellstructurewaspreparedbythe method of hydro-thermal and St?ber method, and modified by (3-aminopropyl) triethoxysilane ( APTES) . The obtained amino-Fe3 O4@SiO2 microsphere with controlled surface charge properties was characterized by SEM and TEM, and the surface electric property of amino-microsphere was investigated by Zeta potential measurement. The microsphere was used to extract DNA from human blood, and the solid phase extraction method by microspheres was developed. The mechanism of action between Aminated-Fe3 O4@SiO2 microsphere and DNA was explored, and the gel electrophoresis and PCR test were done on the extraction product. The result showed that genomic DNA with high purity was successfully extracted from whole blood by using amino-Fe3 O4@SiO2 microsphere, with the extraction rate about 70%, the saturated adsorption capacity for DNA was about 40 ng/μg, and the elution could be directly used for further bio-analysis.

Object To evaluate the efficacy and toxicity of L-asparaginase based regimen for extranodal nasal type NK/T cell lymphoma (ENKTL).Methods 36 patients were treated with L-asparaginase based regimen from February 2008 to November 2011. 20 stage Ⅰ /Ⅱ patients were administered with VLD regimen based chemo-radiotherapy. 4 of 16 stage Ⅲ/Ⅳ patients received modified SMILE regimen chemotherapy, followed by involved field radiation therapy (IFRT), while others received modified SMILE regimen chemotherapy alone.Results Among 36 patients,35 were eligible for treatment response evaluation.The overall response rate (RR) was 68.6% (24/35) with complete response (CR) rate of 54.3% (19/35).After the median follow-up of 13.5 (range 3-31) months,for all patients,the 1-year overall survival (OS) rate was 82 %,and the rate of progression-free survival (PFS) at 1 year was 65 %.The patients who attained response with treatment showed better 1-year OS (93 %) and PFS (80 %) as compared with patients without response (35 %; 33 %),and the differences were statistically significant (x2=13.909,P =0.000; x2=8.216,P =0.004).The major adverse event was myelosuppression. No chemotherapy-related mortality occurred. Conclusion L-asparaginase based regimen is obviously effective and well tolerant for ENKTL. The large prospective clinical trials of L-asparaginase based regimen in the first-line treatment for ENKTL are worth for further investigation.
