Two fragments G1 and G2 of the glycoprotein G gene of bovine respiratory syncytial virus(BRSV) were selected for expression in Escherichia coli based on the analysis of glycoprotein G by DNA Star software.Then the two fragments of glycoprotein G were amplified by PCR with synthesized G gene of BRSV as the template.The amplified fragments G1 and G2 are 570bp and 308bp in length,respectively.The PCR products were cloned into pET30a vector and expressed in soluble form in E.coli after induction of cultured E.coli with IPTG.Both of the recombinant proteins G1 and G2 were purified by immobilized Ni ion affinity chromatography under native conditions.Then the purified proteins were analysed by Western blotting.The results showed that the purified recombinant protein G1 retained good antigenicity and specificity.But the purified recombinant protein G2 didn't possess biological activity.Antibodies against BRSV were detected in suspected bovine serum samples in China by using indirect ELISA and Western blotting with the purified recombinant protein G1.The purified recombinant protein G1 might be used as antigen for establishing serological methods for diagnosis of BRSV infection.And the purified recombinant protein G1 might also be used for preparing polyclonal and monoclonal antibodies for research on biological functions of glycoprotein G of BRSV.

The dry seeds of Cassia obtusifolia were carried by the "ShenZhou 8" satellite and sowed after landing. Based on our pri- or study on SP1, the characteristics of plants growth, physiological index and content of effective components were examined. The results showed that the QC10, QC29 strains matured 5 d earlier compared with control. The plant height, across diameter and ground diameter of QC10, QC29, QC46 strains was superior to the control at whole growth period. The branch number increased ranging from 4 to 11 and the number of pods reached 321, 313,281, respectively, which was dramatically higher than the control (246). The yield of QC10, QC29, QC46 strains increased noticeably from 31.4 to 63.2 g. The 1000-seed-weight of QC10, QC29, QC46 strains was 25.86, 25.88, 24.06 g, while the control was 23.69 g. Compared to the control, the mass fraction of chlorophyll was enhanced 1.098, 1.016, 0.297 mg. There was no significant difference in aurantio-obtusin and chrysophanol content of seeds. Through two years research, three high-yield mutant strains were obtained. This study indicates that spaceflight-induced mutants could provide new germplasm for C. obtusifolia breeding and offers the theoretical basis for further utilization of spaceflight-induced mutation to breed high-quality C. obtusifolia strains.

Objective To study sleep characteristics in patients with temporal lobe epilepsy (TLE) through polysomnography (PSG). Methods Twenty-five TLE patients (TLE group) and eighteen healthy volunteer subjects (control group) were recruited to our study. Patients of two groups were evaluated by whole-night PSG, including total time in bed (TIB), total sleep time (TST), sleep efficiency (SE), sleep latency (SL), rapid eye movement latency (REML), wake after sleep onset (WASO), the percentages of non-REM (NREM) 1, 2 and 3 stages and the percentages of rapid eye movement (REM) occupied TST (N1%, N2%, N3%and REM%), the apnea-hypopnea index (AHI), hypopnea index, mean oxygen saturation (SpO2) and nadir SpO2, periodic leg movements (PLMs) index and PLMs index of REM sleep, sleep stage shifts (SSS) and sleep stage shifts per hour (SSS/h), NREM1, NREM2, NREM3 and REM sleep stage and wake shifts (abbreviated as N1, N2, N3, REM and W) and their proportions of SSS (abbreviated as N1/SSS, N2/SSS, N3/SSS, REM/SSS and W/SSS). Results Compared with control group, WASO, PLMs, PLMs index of REM sleep, SSS, SSS/H and N2 were significantly increased in TLE group. Moreover, compared with control group, SpO2 was decreased in TLE group (P<0.05). Conclusion Our results suggest that TLE patients have sleep disorder manifested as disorder of sleep structure, increased incidents of respiratory and motion events.

To investigate the mechanism of Wenshen Xuanbi Decoction (WSXB) in treating osteoarthritis (OA) via network pharmacology, bioinformatics analysis, and experimental verification. The active components and prediction targets of WSXB were obtained from the TCMSP database and Swiss Target Prediction website, respectively. OA-related genes were retrieved from GeneCards and OMIM databases.Protein-protein interaction and functional enrichment analyses were performed, resulting in the construction of the Herb-Component-Target network. In addition, differential genes of OA were obtained from the GEO database to verify the potential mechanism of WSXB in OA treatment. Subsequently, potential active components were subjected to molecular verification with the hub targets. Finally, we selected the most crucial hub targets and pathways for experimental verification in vitro. The active components in the study included quercetin, linolenic acid, methyl linoleate, isobergapten, and beta-sitosterol. AKT1, tumor necrosis factor (TNF), interleukin (IL)-6, GAPDH, and CTNNB1 were identified as the most crucial hub targets. Molecular docking revealed that the active components and hub targets exhibited strong binding energy. Experimental verification demonstrated that the mRNA and protein expression levels of IL-6, IL-17, and TNF in the WSXB group were lower than those in the KOA group (p < 0.05). WSXB exhibits a chondroprotective effect on OA and delays disease progression. The mechanism is potentially related to the suppression of IL-17 and TNF signaling pathways and the down-regulation of IL-6.

OBJECTIVETo study whether intraspinally transplanted human cord blood CD34+ cells can survive, differentiate, and improve neurological functional recovery after spinal cord injury in rats.
METHODSRats were randomly divided into two groups. One group of rats was subjected to spinal cord left-hemisection and transplanted with human cord blood CD34+ cells labeled by bromodeoxyuridine (BrdU); The other group was carried by left-hemisection with injection of PBS (control group). The neurological function was determined before and 24 h, 1, 2, 3 and 4 weeks after spinal cord injury and cell transplantation using the modified Tarlov score. The distribution and differentiation of transplanted human cord blood cells in vivo in rat spinal cord were evaluated by histological and immnuhistochemical analysis.
RESULTSFunctional recovery determined by modified Tarlov score was significantly improved in the group receiving human cord blood CD34+ cells compared with the control group (P < 0.05). Moreover, human cord blood CD34+ cells were found to survive in rat spinal cord microenvironment, with the expression of the neural nuclear specific protein (NeuN) in 2% BrdU-reactive human cells and of the astrocytic specific protein glial fibrillary acidic protein (GFAP) in 7% BrdU-reactive human cells.
CONCLUSIONSIntraspinally administered human cord blood CD34+ cells can survive, differentiate, and improve functional recovery after spinal cord injury in rats. Transplantation of human cord blood cells may provide a novel strategy for the treatment of neural injury.

BACKGROUNDHereditary spastic paraplegia (HSP) is a group of inherited neurodegenerative disorders with the shared characteristics of slowly progressive spasticity and weakness of the lower limbs. Thirteen loci for autosomal dominant HSP have been mapped.
METHODSA Chinese family with HSP was found in the Shandong province and Inner Mongolia Autonomous Region of China and genomic DNA of all 19 family members was isolated. After exclusion of known autosomal dominant loci, a genome wide scan and linkage analysis were performed.
RESULTSThe known autosomal dominant loci of SPG3A, SPG4, SPG6, SPG8, SPG9, SPG10, SPG12, SPG13, SPG17, SPG19, SPG29, SPG31 and SPG33 were excluded by linkage analysis. The results of a genome wide scan demonstrated candidate linkage to a locus on chromosome 11p14.1-p11.2, over an 18.88 cM interval between markers D11S1324 and D11S1933. A maximal, two point LOD score of 2.36 for marker D11S935 at a recombination fraction (theta) of 0 and a multipoint LOD score of 2.36 for markers D11S1776, D11S1751, D11S1392, D11S4203, D11S935, D11S4083, and D11S4148 at theta=0, suggest linkage to this locus.
CONCLUSIONThe HSP neuropathy in this family may represent a novel genetic entity, which will facilitate discovery of this causative gene.
