ABSTRACT
OBJECTIVE@#To systematically evaluate the efficacy and safety of anterior decompression and posterior decompression in the treatment of thoracolumbar fractures with spinal cord injury, so as to provide a good scientific basis for more effective treatment of thoracolumbar fractures with spinal cord injury.@*METHODS@#A clinical data about comparative study of anterior decompression and posterior decompression in the treatment of thoracolumbar fractures with spinal cord injury was searched and collected. The databases of Pubmed, Embase, Cochrane Library, CNKI, CBM, Wanfang Medical Network were searched by computer. Artificially collected journals included Spine, European Spine Journal, The Journal of Bone and Joint Surgery. Two spine surgeons independently screened the literature according to established inclusion and exclusion criteria and assessed the quality of the included studies. Meta-analysis was performed on the data using Review Manager 5.3 software, the indicators included operative time, intraoperative blood loss, postoperative tactile score, postoperative motor score, postoperative vertebral height, hospitalization time, neurological function recovery, efficiency of treatment, postoperative complications.@*RESULTS@#Fifteen randomized controlled trials (RCTs) were enrolled in a total of 1 360 patients, including 680 anterior decompression and 680 posterior decompression. The results of Meta-analysis showed that the anterior decompression group had longer operation time [MD=80.09, 95% CI(36.83, 123.34), P=0.000 3], more intraoperative blood loss [MD=225.21, 95%CI(171.07, 279.35), <0.000 01], longer hospitalization time [MD=2.31, 95% CI(0.32, 4.31), P=0.02]. And the postoperative tactile score [MD=13.39, 95% CI(9.86, 16.92), <0.000 01], postoperative motor score [MD=13.15, 95% CI(7.02, 19.29), <0.000 1], vertebral height [MD=1.36, 95% CI(0.79, 1.92), <0.000 01] in anterior decompression were higher than that in posterior decompression. There was no statistically significant differences in the efficacy of treatment [OR=1.14, 95% CI(0.56, 2.31), P=0.72], neurological recovery [OR=0.87, 95% CI(0.57, 1.33), P=0.52] between two groups.@*CONCLUSIONS@#Compared with posterior decompression, the anterior decompression has the advantages of longer operating time, more intraoperative blood loss, longer hospitalization time, higher postoperative tactile score, higher postoperative motor score, and higher injury vertebral height, But there was no significant difference in the treatment efficiency and nerve function recovery between two groups.

OBJECTIVE@#To explore the genetic polymorphisms of 16 STR loci from 449 Tibetan Mastiffs in order to set up gene polymorphism database of Tibetan Mastiff.@*METHODS@#The PCR amplification was performed using the 16 STR loci fluorescent multiple amplification kit for dog. The amplified products were detected and statistically analyzed.@*RESULTS@#In the 16 STR loci from 449 Tibetan Mastiffs, CDP was 0.999 999 999 999 999 and CEP was 0.999 997 795. Except FH2010 (10 alleles), PEZ21 (12 alleles), and PEZ05 (13 alleles), the other STR loci had more than 15 alleles. In the 16 STR loci, H was > 0.5 and PIC was > 0.7.@*CONCLUSION@#The 16 STR loci have high polymorphism to be suitable for individual identification and paternity testing of Tibetan Mastiff. The data obtained through this study can be used to establish DNA polymorphism database of Tibetan Mastiff.

OBJECT@#To study sequence polymorphism of mtDNA control region in Chinese Qinghai Tibetan group and Han population.@*METHODS@#Venous blood samples from 69 unrelated Qinghai Tibetans and Han individuals were collected and their mtDNA control region sequences were analyzed. Polymorphism indicators were calculated. The genetic distances based on Fst and Rst among eleven groups from different districts include the Qinghai Tibetan and Han population were elucidated using Nei's method. Phylogenetic tree was constructed.@*RESULTS@#There were 56 polymorphic loci and 59 loci found in the mtDNA control region of Tibetan group and Han population, respectively. It was indicated by the Rst distance that there was a far distance between Qinghai Tibetan and the other populations (P<0.05), and the distance was much closer between Qinghai Han and Xi'an Han, Mongolian, Changsha Han populations (P>0.05).@*CONCLUSION@#There is unique genetic polymorphism of mtDNA control region both in Qinghai Tibetan and Han population. These findings may be useful in forensic identification, population genetic and migration studies.
