Objective To analyze the consistency of individual examination diagnosis with terminologies expressed in the conclusion report of physical examinations by the chief inspection physician. Methods Based on the clinical classifications used in the Guidelines on Prevention and Treatment of Blood Lipid Abnormality for Chinese Adults, and related terminology descriptions of Dyslipidemias that were actually used in four-item blood lipid examinations diagnosis, a lexicon database of Hyperlipidemias was constructed with 39 terms used in the four-item blood lipid examination diagnosis and chief physician conclusions. Totally 11953 electronic chief physician inspection reports from 8 health check-up institutions were included. We investigated the terms of lexicon database using word frequency analysis method, calculated the positive rate in the diagnosis of four single examinations of serum lipid and the positive rate in the chief physician's conclusion. Consistency of chief physician's conclusion with single examination diagnosis was analyzed by Kappa test. Results (1) Among the 39 terms of lexicon database, there are 18 nonstandard terms used in single examination diagnosis, accounted for 46% of all terms; (2) In word frequency analysis, there are only 1% of terms that corresponded to clinical classifications of Hyperlipidemias accurately;(3) The positive rate of Hyperlipidemias in serum lipid four single examinations diagnosis was 47%, the positive rate of physician diagnosis was 35%. The consistency analysis of chief physician conclusions with single examination diagnosis showed Kappa=0.71(P<0.01). Conclusions Although the final conclusion written by the chief physician was not using standard terms strictly, most of synonymous terminology expressed in the physician conclusion is normative, which enabled the construction of lexicon database and text mining. Whether the single examination diagnosis are consistent with physician conclusions can be an evaluation indicator to assess the quality of chief physician conclusions for physical examinations. Kappa>0.75 may be suggested as a favorable value.

Objective To detect the clinical effect of posterior reduction combined with H-shaped bone grafting and spinous process replantation for reconstruction of spinal structures in treatment of thoracolumbar fracture.Methods Forty-three patients with thoracolumbar burst fracture treated surgically from February 2008 to June 2012 were reviewed retrospectively.There were 30 male and 13 female patients aged 23 to 55 years (mean,38 years).Fracture resulted from high falls in 21 patients,traffic accidents in 16 patients,and a crush by heavy objects in 6 patients.Denis system was used for classification of fracture and Frankel rating for assessing the degree of nerve damage and recovery.After posterior reduction combined with H-shaped bone grafting and spinous process replantation for all patients,visual analogue scale (VAS) was utilized to assess symptom improvement and Cobb' s angle and sagittal spinal canal diameter were measured to help assess the treatment outcome.Results Pain was apparently eased at a 24-month follow-up (range,12-46 months).Cobb' s angle improved from preoperative 43.56° to postoperative 8.23° (t =1.33,P < 0.01).CT findings showed mean spinal canal stenosis rate was 56.3% before surgery and that mean sagittal canal diameter of the injured spine was larger than that of adjacent segments at follow-up,with the mean ratio of 116.3% (range,111.3%-120.3%).Rate of spinal canal stenosis was negative for all patients and posterior canal with bone grafts healed.Spinal cord injury improved at least one Frankel grade.Conclusion Posterior reduction combined with H-shaped bone grafting and spinous process replantation is worthy of clinical application,for the procedure can restore the fractured thoracolumbar spine and posterior canal structure,but also effectively avoid the iatrogenic spinal stenosis.

Objective To discuss the association of allele polymorphisms SNP-rs1799724(C>T)in the TNF-αand SNP-rs11559013(G>A)in the ALCAM with HCV chronic infection in Han population in Yunnan province. Methods 434 HCV chronic infectious patients and 444 healthy individuals of Han Chinese population in Yunnan province were recruited. Two single nucleotide polymorphisms(SNPs)in the SNP-rs1799724(C>T) of TNF-αgene and SNP-rs11559013(G>A)of ALCAM gene were determined by real-time TaqMan polymerase chain reaction. We evaluated the associations of the two SNPs with HCV chronic infection. Results The distributions of allele and genotype of SNP-rs1799724(C>T)in the TNF-αand SNP-rs11559013(G>A)in the ALCAM between hepatitis C virus(HCV)chronic infectious patients and the healthy controls were not statistically significant(P > 0.05). Conclusion SNP-rs1799724(C>T)in the TNF-αand SNP-rs11559013(G>A) in the ALCAM have no association with HCV chronic infection in the Han population in Yunnan province.
