Medial Compartment Decompression by Fibular Osteotomy to Treat Medial Compartment Knee Osteoarthritis: A Pilot Study.

Compared with high tibial osteotomy and total knee arthroplasty, the authors found a simpler surgical procedure, partial fibular osteotomy, could effectively relieve knee pain and also correct the varus deformity for patients with medial compartment knee osteoarthritis (OA). From January 1996 to April 2012, a total of 156 patients with medial compartment OA were treated by proximal fibular osteotomy in the authors' hospital. A 2-cm-long section of fibula was resected 6 to 10 cm below the fibular head.

[The pathogenic ecology research on plague in Qinghai plateau].

Objective: To study the pathogenic ecology characteristics of plague in Qinghai plateau.

Methods: Applied molecular biology techniques, conventional technologies and geographic information system (GIS) to study phenotypic traits, plasmid spectrum, genotype, infected host and media spectrum etc.of 952 Yersinia pestis strains in Qinghai plateau plague foci, which were separated from different host and media in different regions during 1954 to 2012.

[Study on the pathogen of plague in Sanjiangyuan area in Qinghai province].

Objective: To study the biological characteristics of Yersinia pestis and to develop prevention and control program on plague in Sanjiangyuan areas, Qinghai province.

Methods: To identify the biologic types and molecular biological features of Y.pestis isolated in Sanjiangyuan area from 1954-2007.

[Study on the genotyping and microevolution of Yersinia pestis in the Qinghai-Tibet Plateau].

Objective: To study the distribution of genomovars and microevolution of Yersinia pestis in the Qinghai-Tibet Plateau.

Methods: Primer pairs targeting the twenty-two different regions(DFRs) were designed for detecting the presence or deletion of each DFR in 297 strains isolated from the Qinghai-Tibet Plateau.

Results: 9 genomovars, i.
