OBJECTIVETo investigate the mothod and therapeutic efficacy of total hip anthroplasties (THA) for osteoarthritis secondary to Crowe type IV developmental dysplasia of hip in adults.
METHODSFrom May 2006 to December 2013, THA was performed on 15 adult patients (17 hips) with Growe type IV acetabular dysplasia, including 13 females and 2 males, with a mean age of 30.9 years old (22 to 58 years old) and an average preoperative Harris score of (34.0 ± 6.5) points. Traction of the affected limb was not performed before surgery. After extensive release and lengthening of soft tissues, sub-trochanteric osteotomy of the femur was performed, hip joint center was rebuilt and the abduction function was restored.
RESULTSThe patients were followed up with a mean period of 33 months (ranged from 6 months to 5 years). The postoperative Harris score was 85.0 ± 7.3,higher than the preoperative score. The extended length of limb ranged from 1.6 to 5.4 cm, with a mean of (3.42 ± 0.65) cm. The shortening and malformation of the affected limb were corrected in the most patients,with the difference in length of the two legs less than 1.5 cm. After surgery, 1 patient experienced partial sciatic nerve injury, which was largely recovered after 3 months of conservative treatment. One patient experienced complete sciatic nerve injury, which was partially recovered after 6 months of conservative treatment; a foot-drop varus deformity was formed in the distal end of the affected limb, which was improved after tendon transposition and transplantation. Joint pain was relieved, and the joint function was restored significantly. Over the follow-up period, no severe complications such as dislocation, infection, prosthesis loosening, or subsiding occurred.
CONCLUSIONSatisfactory efficacy can be achieved for adult Growe type IV acetabular dysplasia associated with osteoarthritis by THA, with proper soft tissue release and lengthening, sub-trochanteric osteotomy of femur, joint functional restoration, appropriate choice of prosthesis, and careful protection of nerves and vessels.

PAK1 plays an important role in the development of tumors. It is of great significance to screen and develop new PAK1 inhibitors as targeted drugs for cancer treatment. The traditional PAK1 inhibitor screening method has the problems of high cost and low efficiency. Computer virtual screening can reduce the cost of finding active lead compounds and improve the screening efficiency. In this study, a kind of PAK1 candidate compound was screened by computer assisted virtual screening combined with Z′lyteTM high flux kinase screen. In vitro enzyme activity screening showed that compound 18(K788)had good PAK1 inhibitory activity(inhibition rate was 42. 7%). Furtherly by MTT detection, it was found that K788 had significant PAK1 positive tumor killing activity, which was even better than the positive drug IPA-3. Flow cytometry and Western Blot showed that K788 could activate caspase apoptosis pathway and induce apoptosis of colon cancer cell DLD-1 by inhibiting PAK1 expression and activation. K788 has great potential for clinical development and application, and can be used as a PAK1 target for further research.

A quantitative analysis method of multi-components with a single marker (QAMS) for simultaneous determination of six marker compounds (one from phenolic acids and five from phthalides) in Chuanxiong Rhizoma was established by applying HPLC and using butylidenephthalide as the internal reference substance. And also the feasibility and accuracy of the established method for quality evaluation and application of Chuanxiong Rhizoma were investigated and validated. The analysis was performed with the mobile phase consisting of acetonitrile - 0.2% aqueous formic acid. The flow rate was 1.0 mL . min-1 and the column temperature was maintained at 30 °C. The detection wavelengths were set at 252 nm (for ferulic acid, Z-ligustilide, and butylidenephthalide) and 266 nm (for senkyunolide I, senkyunolide A, and coniferyl ferulate), separately, and 20 µL was injected for analysis with gradient elution. The results showed that there were no significant differences observed between the HPLC-QAMS method and the external standard method (RSD <5%). The relative correction factors were credible (RSD < 5%) in changed chromatographic conditions. The established HPLC-QAMS method can be accurately used for simultaneously evaluating and controlling the quality of Chuanxiong Rhizoma with multi-components.

Chronic osteomyelitis is one of the most common disorder in clinic. In recent years due to diabetes, peripheral vascular disease and trauma induced disease increased, the prevalence rate increased. With the development of magnetic resonance imaging and CT imaging technology, it greatly improved the accuracy of clinical diagnosis of chronic osteomyclitis and ability to describe the infection characteristics, and provide a reliable basis for clinical treatment. The current research on chronic osteomyelitis mainly concentrated on the aspects of imaging applications and ways of using antibiotic optimization control inflammation, defect restoration and reconstruction of blood supply and treatment. But the best time to the antibiotic therapy and the use of program is still uncertain, for after debridement, bone grafting time and defect repair function of fast recovery still need further research.
