Carotenoids play an important role in regulating the hydrogen production of hydrogen-producing Rhodobacter sp. The carotenoids of hydrogen-producing Rhodobacter sp. grown in acetate medium were extracted by using acetone-methanol (7∶2,V/V) solvent and were separated by using thin-layer chromatography on silica-gel plate. The qualitative and quantitative of the carotenoids were analyzed by spectrometry. The results showed that the carotenoids were completely extracted three times with acetone-methanol (7∶2,V/V) in two hours. The ultrasonication had little effect on yield of carotenoids. The yield of carotenoids was 2.81mg/g wet cell. There were 4 spots on the silica-gel plate in the order of yellow, red, light red and light yellow. Yellow spot and red spot were the dominant composition of carotenoid in Rhodobacter sp. The spectrometry data showed that the yellow and red component might be the spheroidene and spirilloanthin respectively.

Objective To insestigate the pathophysiological mechanisms of spontaneous transient hyperperfusion after cerebral ischemia-reperfusion in rats.Methods Fifty-two SD rats were randomly allocated into sham-operation(group A),cerebral ischcmia 2-hour(group B), and cerebral ischemia 6-hour(group C)groups.Group B were redivided into 0-,0.5-,1-,2-,4-,6-,and 24-hour subgroups according to the reperfusion time;group C were redivided into 0-,0.5-,1-,2-,and 24-hour subgroups according to the reperfusion time (n=4 in each subgroup). Multislice spiral CT perfusion imaging(CTPI)was performed at different time points after ischemia-reperfusion in each group.After completing the scanning.the rats were sacrificed immediately for optical and electron microscopy examinations.Results In group A,compared to the contralateral sides.there were no significant differences in the relatise value of the cerebral blood flow parameters and the results of optical and electron microscopy in the sham-operated regions. In group B, the relative cerebral blood flow (rCBF) and relative cerebral blood volume (rCBV) in the ischemic core area were increased gradually with the extension of reperfusion time. The relative mean transit time (rMTT) and the relative time to peak (rTTP) were decreased gradually, There were no significant differences compared to group A at 6-hour after reperfusion. The optical and electron microscopy revealed that neuronal density in the ischemic core area in group B were decreased, part of the cell volume enlarged and showed vacuolated changes, and part of the neuronal cell bodies and nuclei shrinked, rCBF in the ischemic core area still maintained lower level with the extension of reperfusion time in group C. The ischemic core area showed the increased transient rCBV and rCBV at 0.5 hour after reperfusion in group B and C. The optical and electron microscopy showed that the ischemic core area presented a large number of necrotic and apoptotic cells, and inflammatory cell infiltration. At 6 hours after reperfusion in group B, the increased blood density was observed under the electron microscope in the ischemic core area, showing capillary engorgement and increased pressure. Conclusions The dynamic changes of CTPI in the process of rat middle cerebral artery occlusion and reperfusion have a certain correlation with the pathological mechanisms of injury. The ultra-early spontaneous and transient hyperperfusion after cerebral ischemia-reperfusion in rats is associated with the transient inflammatory hyperemia after reperfusion injury.

OBJECTIVETo study the effect of Bushen Tongdu Capsule (BTC) on RANK/RANKL/ OPG pathway of collagen induced arthritis (CIA) rats, thereby laying theoretic evidence for treating rheumatic arthritis (RA) by Chinese medicine.

METHODSRA model was induced by CIA. Totally 42 rats were randomly divided into six groups, i.e., the normal control group, the model group, the low dose BTC (BSL) group, the medium dose BTC (BSM) group, the high dose BTC (BSH) group, and the Tripterygium Glycosides (TG) group, 7 in each group. BTC at the daily dose of 120, 240, and 480 mg/kg was given by gastrogavage to rats in the BSL, BSM, and BSH group respectively from the 13th day of modeling. TG at the daily dose of 24 mg/kg was given by gastrogavage to rats in the TG group. All medication was given once daily, 2 mL each time. Two mL normal saline was administered to rats in the normal control group and the model group. All medication lasted for 18 days. Samples were taken at day 31. The TRAP section of the ankle joint was fixed in 10% formalin for TRAP stain. Serum levels of osteoprotegerin (OPG), receptor activator of nuclear factor-κB ligand (RANKL), and macrophage colony-stimulating factor (M-CSF) were detected using ELISA.

RESULTSCompared with the normal control group, positive reactions of pathological ankle joint section, inflammation, and osteoclasia degree were significantly improved in the model group, serum levels of RANKL and M-CSF were up-regulated, levels of OPG and OPG/RANKL were significantly lowered (all P < 0.01). Compared with the model group, positive reactions of pathological ankle joint section, inflammation, and osteoclasia degree also significantly decreased in the BSH group and the TG group (all P < 0.01). RANKL and M-CSF were significantly down-regulated in each medicated group, while levels of OPG and OPG/RANKL were significantly up-regulated (all P < 0.01). Compared with the TG group, M-CSF was lower, but levels of OPG and OPG/RANKL were significantly up-regulated in the normal control group (all P < 0.01). RANKL and M-CSF were significantly up-regulated, while levels of OPG and OPG/RANKL were significantly down-regulated in the model group and each BS group (all P < 0.01).

CONCLUSIONBTC could relieve bone damage of CIA rats possibly through regulating and controlling osteoclasts.

OBJECTIVETo investigate the effects of FTY720, a new immunosuppressive agent, on apoptosis and autophagy in multiple myeloma(MM) cell line U266 and to clarify its molecular mechanism.

METHODSU266 cells were treated with 0, 2.5, 5.0, 10.0 and 20.0 µmol/L FTY720 for 24 hours, and the cell viability was assayed by CCK-8 method. Then U266 cells were treated with 20.0 µmol/L FTY720 for 0, 2, 6 and 24 hours, the cell viability was tested. The apoptotic rates induced by different doses and time points of FTY720 were tested by flow cytometry separately. The expression of LC3B was detected by Western blot after U266 cells treated with different doses of FTY720 to see autophagy. U266 cells were treated with FTY720 ± Bafilomycin A1, an inhibitor of autophagy, for 24 hours, then the cell viability and apoptotic rates were tested. Meanwhile the expression of survivin, anti-apoptotic factors, were tested by Western blot.

RESULTSThe cell viability and the apoptotic rates were inhibited significantly by FTY720 (P < 0.05) in time-dependent and dose-dependent manner. The expression of LC3B-II increased significantly in a dose-dependent manner, it indicated that the autophagy was induced by FTY720. Bafilomycin A1 could rescue the cell viability and apoptotic rates in U266 cells treated with FTY720, and it could also rescue the expression of survivin decreased by FTY720.

CONCLUSIONSFTY720 can cause apoptosis and autophagy of U266 cells. The autophagy promote the apoptosis, which maybe due to the degradation of anti-apoptotic factors such as survivin or their upstream factors in lysosomes through autophagy.

XI Hong, a famous acupuncturist in the Southern Song Dynasty, has an important influence and status in history of Chinese acupuncture and moxibustion. After he moved to Linchuan, Jiangxi province, his descendants passed acupuncture from generation to generation. According to records, it was passed to 12 generations. After the tenth generation, it was also passed to apprentices besides descendants, such as accomplished acupuncturists CHEN Hong-gang, LIU Jin and others, forming XI Hong acupuncture school of thought. The poem of acupuncture and moxibustion XI Hong Fu is the representative work about XI Hong academic thought, which was additionally compiled or written by XI Hong's apprentices according to XI Hong academic thought. The poems are of characteristics in acupuncture application and association of acupoints. The academic thought and therapeutic methods of acupuncture in the poems still are widely used in modern clinical acupuncture practice.

Moderate drought stress has been found to promote the accumulation of active ingredients in Glycyrrhiza uralensis root and hence improve the medicinal quality. In this study, the transcriptomes of 6-month-old moderate drought stressed and control G. uralensis root (the relative water content in soil was 40%-45% and 70%-75%, respectively) were sequenced using Illumina HiSeq 2000. A total of 80,490 490 and 82 588 278 clean reads, 94,828 and 305,100 unigenes with N50 sequence of 1,007 and 1,125 nt were obtained in drought treated and control transcriptome, respectively. Differentially expressed genes analysis revealed that the genes of some cell wall enzymes such as β-xylosidase, legumain and GDP-L-fucose synthase were down-regulated indicating that moderate drought stress might inhibit the primary cell wall degradation and programmed cell death in root cells. The genes of some key enzymes involved in terpenoid and flavonoid biosynthesis were up-regulated by moderate drought stress might be the reason for the enhancement for the active ingredients accumulation in G. uralensis root. The promotion of the biosynthesis and signal transduction of auxin, ethylene and cytokinins by moderate drought stress might enhance the root formation and cell proliferation. The promotion of the biosynthesis and signal transduction of abscisic acid and jasmonic acid by moderate drought stress might enhance the drought stress tolerance in G. uralensis. The inhibition of the biosynthesis and signal transduction of gibberellin and brassinolide by moderate drought stress might retard the shoot growth in G. uralensis.
