Objective: To observe the effect of scraping therapy (ST) on the immune balance of serum helper T (Th) 1/Th2 cells in autologous nucleus pulposus transplantation non-compressive lumbar disc herniation (LDH) model rats, and explore the immune mechanism of ST in reducing LDH pain. Methods: Seventy-two male Sprague-Dawley (SD) rats were randomly divided into a model group, a sham operation group and a ST group, with 24 rats in each group. Autologous nucleus pulposus transplantation non-compressive LDH models were established in the model group and ST group, while the rats in the sham operation group underwent sham operation without model establishment. On the fifth day after the model was successfully prepared, rats in the ST group received ST, once every other day, 3 times as a course for a total of 3 courses. Six rats in each group were randomly selected to observe their pain thresholds, and peripheral blood of the rats was collected before the first scraping treatment and at the end of the first, second, and third courses of treatment. The serum was isolated and enzyme-linked immunosorbent assay (ELISA) was applied for the detection of rat serum interferon (IFN)-γ, interleukin (IL)-4 and IL-10. Results: Compared with the model group, the pain threshold in LDH rats in the ST group increased (P<0.05), the serum IFN-γ level was significantly reduced (P<0.05), but the levels of IL-4 and IL-10 did not change significantly (both P>0.05). At the end of the second and third courses of treatment, the IFN-γ/IL-4 ratio was negatively correlated with the pain threshold in the rats, and the IFN-γ/IL-4 ratio was significantly reduced in the ST group (P<0.01). Conclusion: ST can help suppress the Th1 immunity in LDH rats triggered by the autologous nucleus pulposus, restore the immune balance of Th1/Th2, and reduce the pain of LDH.

RNA methyltransferase is responsible for transferring methyl and resulting in methylation on the bases or ribose ring of RNA, which existed widely but mostly remains an open question. A recombinant protein PH1948 predicting RNA methyltransferase from Pyrococcus horikoshii OT3 has been crystallized. The crystals of selenomethionyl PH1948 belong to space group C2, with unit-cell parameters a=207.0 A, b=43.1 A, c=118.2 A, b=92.1 degrees , and diffract X-rays to 2.2 A resolution. The V(M) value was determined to be 2.8 A3/Da, indicating the presence of four protein molecules in the asymmetric unit.

ObjectiveTo observe the influence of rehabilitation training on heart rate of stroke patients in the early stage.MethodsThe heart rate (HR) of 30 patients within one week after the onset of stroke was evaluated by FUKUDA DS 880A teleelectrocardiograph and the rating of perceived exertion (RPE) was collected during practicing bridging, rolling and moving the arms.ResultsThe HR of 30 patients was only increased 7.57, 6.23 and 6.57 beats per minute during practicing bridging, rolling and moving the arms. RPE of all patients was less than 11.ConclusionAppropriate rehabilitation training is safety and unable to increase the loading of heart in the early stage after the onset of stroke.

In order to provide scientific basics for exploitation and sufficient application of Dendrobium officinale leaves resources, the phenol-sulfuric acid method was applied to determine the polysaccharide content. The monosaccharides were derivated by PMP and the derivatives were identified by HPLC-DAD-ESI-MS(n) and the contents of mannose and glucose were determined simultaneously. Similarity evaluation system for chromatographic fingerprint of traditional Chinese medicine (2004A) was employed to generate the mean chromatogram and similarity analysis of the samples was carried out. The results demonstrated that polysaccharide content, monosaccharide compositions and composition ratio had an obvious difference between stems and leaves. The polysaccharide content of stems was higher than that of leaves. Monosaccharide composition in leaf was significantly different from that in stem. The polysaccharide from stems was composed of mannose and glucose, however the polysaccharide of leaves was acid heteropolysaccharide and was mainly composed of five monosaccharides, including mannose, galacturonic acid, glucose, galactose and arabinose. The similarity value of the 14 batches was above 0.9, indicating that similarity of fingerprints among different samples was high. The study can provide evidence for expanding the medicinal parts of D. officinale.
