OBJECTIVETo identify the affect of chronic low back pain on multifidus muscle atrophy and fatty infiltration.

METHODSFrom March 2010 to August 2013, a retrospective study were carried out in the department of orthopedics of patients with low back pain. Finally 31 cases were selected to this study including 19 males and 12 females with an average age of 36.4 years ranging from 23 to 55 years. The main symptoms of these patients were repeated back pain. Duration was more than 1 year. X-ray, CT, MRI showed no obvious abnormalities. The changes of net cross-sectional area of multifidus and T2 signal ratio of the same patient were measured at different time by MRI. VAS and Oswestry disability scores were recorded in two MRI examination. Correlation between these change of multifidus net area and T2 signal ratio in two times measurement and duration of low back pain, VAS, Oswestry disability scores were analyzed to find the affection of low back pain on paraspinal multifidus muscle.

RESULTSThe net multifidus cross-sectional area in same case by the second follow-up MRI is significantly smaller than that of the first follow-up, T2 signal ratio at second was significantly higher than that of the first (P < 0.05). The net cross sectional area of multifidus muscles reduced rate were positively correlated with VAS scores, duration and of Oswestry disabilitry scores (P < 0.001). The rate of increase in T2 signal ratio was not correlated with VAS scores,duration and the Oswestry disability scores (P > 0.05).

CONCLUSIONChronic low back pain is one of the most important reasons of paraspinal multifidus muscle atrophy and fatty. The duration, VAS and Oswestry disability scores of chronic low back pain were positively correlated with the multifidus muscle atrophy.

Based on the complete genome sequence of Newcastle disease virus (NDV) ZJI strain,seven pairs of primers were designed to amplify a cDNA fragment for constructing the plasmid pNDV/ZJI,which contained the full-length cDNA of the NDV ZJI strain.The pNDV/ZJI,with three helper plasmids,pCIneoNP,pCIneoP and pCIneoL,were then cotransfected into BSR-T7/5 cells expressing T7 RNA polymerase.After inoculation of the transfected cell culture supernatant into embryonated chicken eggs from specific-pathogen-free (SPF) flock,an infectious NDV ZJI strain was successfully rescued.Green fluorescent protein (GFP) gene was amplified and inserted into the NDV full-length cDNA to generate a GFP-tagged recombinant plasmid pNDV/ZJIGFP.After cotransfection of the resultant plasmid and the three support plasmids into BSR-T7/5 cells,the recombinant NDV,NDV/ZJIGFP,was rescued.Specific green fluorescence was observed in BSR-T7/5 and chicken embryo fibroblast (CEF) cells 48h post-infection,indicating that the GFP gene was expressed at a relatively high level.NDV/ZJIGFP was inoculated into 10-day-old SPF chickens by oculonasal route.Four days post-infection,strong green fluorescence could be detected in the kidneys and tracheae,indicating that the recombinant GFP-tagged NDV could be a very useful tool for analysis of NDV dissemination and pathogenesis.

The purpose of the present study was to explore whether substance P (SP) modulates the response mediated by GABAA receptors. Experiments were carried out on cultured hippocampal pyramidal neurons of rats. GABA-activated inward currents were recorded using the whole-cell-patch-clamp techique. The majority of the neurons examined (66/92, 72%) were sensitive to both GABA and SP. When the neurons were treated with SP prior to application of GABA, the GABA-activated current (IGABA) was inhibited markedly, which was concentration-dependent and could be blocked by spantide, an NK1 receptor antagonist. With 10－8, 10－7, 10－6 and 10－5 mol/L SP, IGABA was inhibited by 18%, 24.8%, 25.9% and 28% respectively. Intracellular application of H7, a potent inhibitor of PKC, abolished inhibition of IGABA by SP, suggesting that the inhibition of IGABA by SP may be a result of intracellular phosphorylation of the GABAA receptor.

AIM To explore analgesic mechanism of Yaobitong Capsules (Notoginseng Radix et Rhizoma,Chuanxiong Rhizoma,Corydalis Rhizoma,etc.) on lumbar intervertebral discs.METHODS An array of data mining,molecular docking and network analysis were employed to investigate the active compounds and key target protein.RESULTS Among the forty-six active hits identified by virtual screening,most compounds displayed good oral bioavailability and might confer an optimal CNS exposure.And eleven molecules (coptisine,diligustilide,corypalmine,chuanxiongterpene,etc.) were further confirmed to alleviate lumbar intervertebral discs through their targeting at nineteen proteins (such as p38,CGRP,MMPs,TNFα) to inhibit the inflammatory response and the infiltration of microvasculature,to reduce the nociceptors sensitivity,and to modulate the balance of Collagen and proteoglycans in catabolic and anabolic responses.CONCLUSION Yaobitong Capsules' clear molecular working mechanism and the key active compounds are revealed by this network-assisted investigation highlight the subsequent experiments on targets and active compounds.

Based on the complete genome sequence of pigeon-origin Newcastle disease virus strain JS/07/04/ Pi(genotype VIb), nine overlapped fragments covering its full-length genome were amplified by RT-PCR. The fragments were connected sequentially and then inserted into the transcription vector TVT7/R resulting in the TVT/071204 which contained the full genome of strain JS/07/04/Pi. The TVT/071204 was co-transfected with three helper plasmids pCI-NP, pCI-P and pCI-L into the BSR cells, and the transfected cells and culture supernatant were inoculated into 9-day-old SPF embryonated eggs 60 h post-transfection. The HA and HI tests were conducted following the death of embryonated eggs. The results showed that the allantoic fluids obtained were HA positive and the HA could be inhibited by anti-NDV serum which indicated that the strain JS/07/04/Pi was rescued successfully. The rescued virus rNDV/071204 showed similar growth kinetics to its parental virus in CEF. The successful recovery of this strain would contribute to the understanding of the host-specificity of pigeon-origin NDV and to the development of the novel vaccines against the NDV infection in pigeons.

OBJECTIVETo analyze the relationship between DNA content and biological behavior and its prognostic significance in non-small cell lung cancer.

METHODSTumor DNA content was determined by flow cytometry in the specimens from 58 patients with resected non-small cell lung cancer. The DNA content of each cell subpopulation was expressed as the DNA index (DI), and an internal standard was provided by the normal pulmonary parenchymal cells in the same specimen. The prognostic value of DNA content in non-small cell lung cancer was assessed by Cox's model analysis.

RESULTSIn qualitative analysis, there was no relationship between DNA ploidy (diploidy or aneuploidy) and the following factors: tumor size, metastasis of lymph node, clinical stage, pathologic type, pathologic grade or survival. In quantitative analysis, high DNA index was observed in tumor size > 3 cm, metastasis of lymph node, stage III/IV, adenocarcinoma and shorter survival, which was statistically significant. Cox's model analysis showed that DNA index was a prognostic factor in non-small cell lung cancer and DNA index > 2.0 was an independent prognostic factor.

CONCLUSIONDNA index analysis is useful for the evaluation of the biological behavior and the prognosis of non-small cell lung cancer.
