Objective Acquiring genetic information of Y-SNPs and Y-STRs genetic makers from samples with the surname of Kong, which is useful for exploring the correlation between surname and Y chromosome in forensic applications studies.Methods Two multiplex genotyping assays and SNaPshot assay were used to analyze 255 unrelated male blood samples who share the same surname Kong and 330 unrelated male blood samples obtained randomly. 17 Y-STRs were typed for the surname Kong population samples. The software Arlequin 3.5.1.2 and the program Network 4.6.1.1 were used for data statistical analysis.Results 13 haplogroups were observed. The highest haplogroup frequency in the two populations were O3a2c1a-M117 (21.57%, 14.85%). 196 haplotypes in Kong population deifned by 17 Y-STRs locus were obtained and the haplotype diversity was 0.9939. 14-12-25-28-19-15-12-19-12-11-12-22-12-11-14-10-19 is the typical haplotype. Median Joining algorithm and Mismatch Distribution were adopted to analyze the Y-STR haplotye under haplogroup O3-M122, and the result shows that there are two “central star” distribution. Conclusion Combined with Y-SNP and Y-STR analysis showed that the Kong population had experienced complicated exchanges and expansion or continued growth, which has more than one surname origin. Hence, its population genetic structure and historical differences have potential applications in forensic science.

Objective Simvastatin, as a widely used lipid-lowering drug, exhibits a potential effect of promoting bone forma-tion. The present study aimed to investigate the effect of oral simvastatin on lumbar vertebral bone mass and intervertebral disc ( IVD) degeneration in ovariectomized ( OVX ) rats. Methods Thirty female Sprague-Dawley rats were subjected to dual OVX ( n=20) or sham surgery ( n=10) and the OVX rats were treated orally with either saline vehicle (OVX+V, n=10) or simvastatin (OVX+SIM, n=10 ) at 5 mg per kg of the body weight per day. After 6 months of intervention, the microstructure of the L3 vertebra was ob-served by micro-CT, the bone mineral density ( BMD) in the L5-6 ver-tebrae determined by dual-energy X-ray absorptiometry, and histo-logical changes of the L5-6 vertebrae analyzed by van Gieson stainingand semi-quantitative evaluation. Results Compared with the sham-operation group, both the OVX+V and OVX+SIM groups showed significantly decreased BMD in L5([0.2933±0.0110] vs [0.2423±0.0081] and [0.2598±0.0249] g/cm2, P<0.05), L6 ([0.2907±0.0150] vs [0.2395±0.0061] and [0.2572±0.0121] g/cm2, P<0.05), and L5-6([0.2860±0.0115] vs [0.2380± 0.0059] and [0.2528±0.0126] g/cm2, P<0.05), but all the 3 parameters were remarkably higher in the OVX+SIM than in the OVX+V group (P<0.05). Micro-CT analysis manifested significantly lower BV/TV and Tb.N but higher Tb.Sp in the OVX+V than in the sham operation group ( P<0.05) . Abundant notochordal cells and extracellular matrix in the nucleus pulposus with well-arranged outer annulus fibrosus were observed in the rats of the sham operation group. The animals of the OVX+V and OVX+SIM groups displayed de-generation of the nucleus pulposus, annulus fibrosus, reduced notochordal cells and their replacement by chondrocyte-like cells in the nucleus pulposus, mucoid degeneration in the matrix, and disruption of the nuclear-annular border in the annulus fibrosus. The disc de-generation scores were significantly higher in the OVX+V and OVX+SIM than in the sham operation group (4.35±0.9 and 3.53±0.42 vs 2.48±0.92, P<0.05). Conclusion OVX induces not only bone loss in vertebrae but also IVD degeneration in rats, while simvasta-tin can partly prevent bone loss in lumbar vertebrae without aggravating IVD degeneration in OVX rats.
