Osteoporosis is a complex disease caused by genetic and environmental factors,which the genetic architecture is not completely understood.Genome-wide association study(GWAS)have reformed the identification of genetic determinants of complex diseases including osteoporosis.In the past decade, more than 30 GWASes which were related to bone mass density identified nearly 100 independent loci.The bivariate GWAS approach is an effective approach to detect pleiotropic genes for two osteoporosis traits. However, genetic analyses must be combined with functional studies to understand the underlying mechanisms.The insight of bone metabolism by GWAS is of huge potential for the identification of novel drug targets for osteoporosis.

Sorghum (Sorghum bicolor L.) was one of the most important crops in the world next to wheat, rice, maize, soybean and barley. Using the callus derived from immature inflorescence as the recipients, we efficiently transformed sorghum varieties 115, ICS21B and 5-27 with the insecticidal Bacillus thuringiensis (Bt) cry1Ab gene carried in the T-DNA of binary vectors which contained hygromycin resistance gene and gus gene via Agrobacterium tumefaciens. After gradient selection with hygromycin, a total of 21 independent transgenic plant lines, 52 transgenic plants were regenerated, and the average stably transformation efficiency was 1.9%. The integration and transcription of cry1Ab gene in transgenic sorghum was confirmed by PCR analysis, Southern blotting and RT-PCR analysis. The Bt proteins were expressed in most transgenic plants with different level from plant to plant by Western blotting and ELISA assay. According to insect bioassay in laboratory, the transgenic plants with a relatively high level of Bt gene expression displayed insect-resistance to pink rice borer (Sesamina inferens).

Objective:To investigate the value of serum miR-143 level combined with MRI in predicting the early response to concurrent chemoradiotherapy (CCRT) in cervical cancer.Methods:A total of 85 patients with pathologically confirmed cervical cancer underwent conventional MRI, intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI), and dynamic contrast-enhanced MRI (DCE-MRI) before CCRT. The biopsy tissues and serum samples were collected. The differential expression of miRNA in the biopsy tissues was determined by microarray chip. The expression level of miR-143 in the serum samples was analyzed by qRT-PCR. All patients were divided into the non-residual and residual tumor groups according to post-treatment MRI. Pre-treatment clinical factors, MRI parameters and miR-143 between two groups were statistically analyzed by the univariate and multivariate analyses. The optimal thresholds and predictive performance for post-treatment incidence of residual tumors were estimated by drawing the ROC curve.Results:At one month after CCRT, there were 52 patients in the non-residual tumor group and 33 patients in the residual tumor group. In the residual tumor group, pre-treatment FIGO staging, apparent diffusion coefficient (ADC), D and V e were significantly higher (all P<0.05), whereas K trans value was significantly lower ( P<0.001) when compared to those in the non-residual tumor group. The miRNA array analysis showed that there were 16 miRNAs with differential expression levels between two groups (all P<0.05). Among them, the increase of miR-143 was the most significant in the residual tumor group. Compared with the residual tumor group, the expression level of serum miR-143 was significantly down-regulated in the non-residual tumor group ( P=0.002). Compared with the SiHa cells, the expression level of miR-143 in the SiHa-R cells was significantly up-regulated ( P<0.05). Multivariate analysis showed that only miR-143, D, K trans and V e were the independent prognostic factors. The combination of multi-parametric MRI and miR-143 exhibited the highest predictive performance (AUC=0.975), with a sensitivity of 84.8% and a specificity of 96.2%. Conclusion:The combination of multi-parametric MRI with miR-143 further improves the predictive performance for residual tumors after CCRT, which contributes to the personalized treatment of cervical cancer.

Primary hypertrophic osteoarthropathy(PHO) is a rare disease also known as pachydermoperiostosis. We reported a painless case whose diagnosis was confirmed by genetic test. A 24-year-old male presented a series of symptoms that first began at 14. He suffered from progressive clubbed-fingers accompanied by swelling of the wrist and ankle joints. Facial skin concentric thickening and alar nose broadening appeared simultaneously and increased progressively. He was also prone to acne and hyperhidrosis. X-rays showed thickening of the metacarpal and phalangeal bones, as well as symmetrical periosteal ossification of both the tibia and fibula. Clinical diagnosis of PHO is difficult because of the variable features. With acromegaly excluded, the diagnosis was confirmed by a genetic test. Whole exome sequencing revealed a heterozygous

ObjectiveBased on network pharmacology and molecular docking techniques, the mechanism of essential oil from Chimonanthus nitens leaves (CLO) in the treatment of acute lung injury (ALI) was predicted, and a rat model of ALI was established to verify the mechanism of CLO. MethodThe composition of CLO was determined by gas chromatography-mass spectrometry (GC-MS). The component targets were obtained from PharmMapper and SwissTargetPrediction databases, ALI-related targets were obtained from GeneCards, Online Mendelian Inheritance in Man (OMIM) and DisGeNET, cross-over analysis with differential expressed genes (DEGs) of ALI obtained from Gene Expression Omnibus (GEO) on the Venny 2.1.0 platform yielded potential anti-ALI targets of CLO. Protein-protein interaction (PPI) analysis of potential targets was carried out by STRING 11.5. The tissue expression profiles of potential targets were obtained from the National Center for Biotechnology Information (NCBI) and the target tissue distribution maps were constructed. Potential targets were analyzed for Gene Ontology (GO) function and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment by RStudio 4.0.0 software. Composition-target-pathway network was constructed by Cytoscape 3.9.1 software, and key components and pathways were screened out and verified by molecular docking. ALI model was established by lipopolysaccharide (LPS) induction, levels of interleukin (IL)-6 and tumor necrosis factor (TNF)-α in serum of rats were measured, the expression levels of IL-17 protein in the lung tissue of ALI rats were analyzed by immunohistochemistry. ResultA total of 19 components of CLO were identified by GC-MS, and 18 potential targets were obtained by target screening. After PPI analysis, 15 target proteins with interaction relationship were obtained, further analysis showed that they were highly expressed in lung and thymus. The network diagram of component-target-pathway was analyzed to obtain the key components, including bornyl acetate, linalool, elemol, geranyl isobutyrate, and the core targets of matrix metalloproteinase 13 (MMP13), S100 calcium binding protein A9 (S100A9), spleen tyrosine kinase (SYK), as well as the main signaling pathways, such as IL-17 and TNF. The results of molecular docking showed that the key components were stably bound to MMP13 and S100A9 of IL-17 signaling pathway. The results of pharmacological experiment confirmed that CLO could significantly inhibit the expression of IL-6 and TNF-α in serum of ALI rats, and decrease the expression of IL-17 protein in lung tissue of ALI rats. ConclusionCLO can achieve the therapeutic effect on ALI and protect lung tissue, the mechanism may be related to the decrease of the expression of IL-6 and TNF-α in serum and the inhibition of the activation of IL-17 signaling pathway in lung tissue of ALI rats.
