A novel Gram-stain-negative, aerobic, non-spore-forming, non-motile and rod-shaped bacterial strain, designated DHOA04T, was isolated from a forest soil sample collected at Dinghushan Biosphere Reserve, Guangdong Province, PR China (112° 31' E 23° 10' N). It grew optimally at 28-33 °C and pH 6.5-7.0. Strain DHOA04T contained Q-8 as the major respiratory quinone. Its main fatty acids were C16 : 0, C17 : 0cyclo, summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c) and summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c). The DNA G+C content of DHOA04T was 63.0 mol%, which is in the range of the genus Paraburkholderia. The average nucleotide identity and digital DNA-DNA hybridization values for the complete genomes were 81.6-83.0 and 25.5-27.0 % between strain DHOA04T and five closely related type strains. The major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and two unidentified aminophospholipids. On the basis of 16S rRNA gene sequence analysis, the strain was found to be closely related to members of the genus Paraburkholderia, but clearly separated from the established species. Phylogenetic analysis based on the 16S rRNA gene sequences using the maximum-likelihood algorithm indicated that strain DHOA04T was most closely related to Paraburkholderia ferrariae NBRC 106233T. The phenotypic, chemotaxonomic and phylogenetic data, and genome analysis showed that strain DHOA04T represents a novel species of the genus Paraburkholderia, for which the name Paraburkholderia dinghuensis sp. nov. is proposed. The type strain is DHOA04T (=KCTC 42627T=LMG 28839T).

OBJECTIVE: To compare the clinical effects of different fixing methods for intertrochanteric fractures and make theoretical analysis. METHODS: From June 2003 to June 2007, 321 patients with intertrochanteric fractures, male 132 and female 189, ranging in age from 20 to 93 years with an average of 56.8 years, were treated with different fixation including Richard nail (142 cases), proximal femora nail (PFN, 94 cases) and external fixator (85 cases). The clinical data of all the patients were retrospectively analyzed, including the incidence of complications, joint function of hip (according Kudema modified Merli D'Aubigne criteria). RESULTS: All patients were followed up from 10 months to 4 years with an average of 14 months. About the incidence of complications, there was significant difference between the external fixator group and the others two groups (P < 0.05); there was no significant difference between the Richard nail group and the PFN group (P > 0.05). There was significant difference in joint function of hip among three methods. PEN group was best than others two groups. CONCLUSION: There is the best clinical effects and lowest incidence of complications with PFN method, which is the better choice in treating intertrochanteric fractures.
