Objective To study the correlation between normal level of thyroid hormone and gensini coronary scor-ing system. Methods Coronary heart disease patient who were treated with Cardio-angiography (CAG) (n=231) were divid-ed into 4 groups based on gensini coronary score. All the patients were examined with indexes include total triiodothyronine (TT3), total thyronine(TT4), free thyronine(FT4), free triiodothyronine (FT3), thyroid stimulating hormone (TSH). And correla-tion between thyroid hormone level and gensini coronary scoring system was studied by Spearman correlation analysis and Multiple regression analysis. Results No significant difference was found in the levels of TT3, TT4, FT4, Cholesterol(CHO) and Triglyceride(TG) between the all 4 groups (P>0.05). FT3 and HDL-C decreased with the increase of extent of coronary artery lesions(P<0.01), and AGE and LDL-C raised with the coronary artery lesions extent (P<0.05). Gensini coronary scoring system was linearly negatively correlated with FT3, HDL-C and positively correlated with age and LDL-C. Age, FT3,HDL-C,LDL-C was independently correlated to Gensini score. Conclusion The lower level of FT3 is an indepen-dent risk factor for CHD.

Objective:To study the effects of several herbal medicines on SMMC-7721 liver cancer cells with Fourier transform infrared spectrometer(FTIR). Methods: FTIR was employed to determine the infrared spectra(IRs) of SMMC-7721 liver cancer cells cultivated for 20 h with the extracts of Spica prunellae, Herba houttuyniae, Radix bupleuri and Herba artemisiae scopariae. Cluster analysis of IRs was also performed. Results: IR spectral parameters such as band shape, intensity and frequency of the blank, control and herbal-extract-treated cells were compared. There existed obvious blue shift of ? s(PO 2 -), ? as (PO 2 -) bands, red shift of ? as (CH 3), ?(CH 2) bands on the herbal-extract-treated cells IRs. The decreasing ratio of ? as (CH 3) to ? s(CH 2) peak intensity and the increasing ratio of ? s(PO 2 -) to ?(N-H) peak area indicated the destructive effect of herbal extracts on the membrane structure of SMMU-7721 cells and inhibitory effect on the DNA replication respectively. Cluster analysis successfully discriminated the herbal-extract-treated cells from the blank cells and the liver-oriented medicines from the non-liver-oriented medicine. Conclusion: FTIR provides another fast and effective approach to analyze the changes of cells treated with Chinese herbal medicines, which may help to illuminate the functional mechanism of Chinese herbal medicines.

Along with the development of economy and society, type 2 diabetic mellitus (T2DM) has become one of the most common diseases at the global level. As one of the complications of T2DM, diabetic neuropathic pain (DNP) stubbornly and chronically affects the health and life of human beings. In the pain field, dorsal root ganglion (DRG) is generally considered as the first stage of the sensory pathway where the hyperexcitability of injured neurons is associated with different kinds of peripheral neuropathic pains. The abnormal electrophysiology is mainly due to the changed properties of voltage-gated sodium channels (VGSCs) and the increased sodium currents (I(Na)). Curcumin is an active ingredient extracted from turmeric and has been demonstrated to ameliorate T2DM and its various complications including DNP effectively. The present study demonstrates that the I(Na) of small-sized DRG neurons are significantly increased with the abnormal electrophysiological characteristics of VGSCs in type 2 diabetic neuropathic pain rats. And these abnormalities can be ameliorated efficaciously by a period of treatment with curcumin.

Age - related macular degeneration ( AMD ) is the leading cause of irreversible visual loss in elderly people among white - dominated population. At percent, treatment for AMD includes anti - vascular endothelial growth factor antibody ( Anti- VEGF ) drug treatment, photodynamic therapy ( PDT ) , topical application of triamcinolone acetonide ( TA ) and laser therapy ( nanosecond laser) etc. Through comparative analysis of different treatment methods of AMD, we review the mechanism, clinical efficacy, adverse events and cost effectiveness to provide the basis for clinical treatment.

Background Subretinal transplantation of retinal pigment epithelium (RPE) cells for the treatment of age-related macular degeneration (AMD) have accelerated the drive to develop xeno-free cultivation system that support the rapid differentiation of human embryonic stem cells (hESCs) into ES-RPE cells.Objective This study was to report a modified xeno-free culture system and method for accelerating derivation of hESCs to differentiate into RPE cells.Methods This study was approved by Ethic Committee of Zhongshan Ophthalmic Center.HESC H1 line was cloned and cuhured in Vitronectin XFTM-coated 6-well dish with xenogenetic-free medium.Cells were cultured in 50 ng/ml noggin,10 ng/ml DKK-1 and 10 ng/ml insulin like growth factor-1 (IGF-1) medium for 2 days,and then the concentration of noggin was decreased to 10 ng/ml and 5 ng/ml basic fibroblast growth factor (bFGF) and cultured for the following 2 days.Sequentially,noggin and bFGF were removed and cultured for 2 days.Finally,1 μmol/L CHIR99021 was added in medium for 6 days.Morphological changes in the progress of ESCs differentiation into RPE were observed by Living Cell Imaging System.The expression of Mitf and RPE65,RPE cellsspecific markers,in the cells were detected by immunofluorescence technique,and the relative expression levels of RPE cells-specific marker mRNA were assayed using real time fluorescent quantitation PCR.Results Polygonalshape monolayer cells which contained pigments were initially observed at day 14 after cultured with the cobblestonelike arrangement.Mitf and RPE65 were strongly expressed in the hES-derived RPE cells 35 days after induced,showing red fluorescence,and the cells presented hexagonal shape at cultured day 60 with numerous pigment granules in cytoplasm.Compared with before differentiation,the expression levels of Mitf mRNA in hES-RPE cells increased by (3.43±2.77) folds and (8.91 ± 2.83) folds,and the expression levels of RPE65 mRNA increased by (14.60 ± 3.94) folds and (87.16 ±9.32) folds at day 7 and day 14 after differentiation,respectively (all at P＜0.05).Conclusions A defined xeno-free culture system is successfully established by adding niacinamide,DKK-l,noggin,IGF-1 and CHIR99021 in xeno-free medium,and this system can accelerate the derivation and differentiation of hESCs into RPE-like cells.

[Objective] To investigate the expression of MICA mRNA and protein in osteosarcoma and give a more comprehensive understanding to its immune evasion.[Methods] RT-PCR was used to analyze MICA mRNA in 11 osteosarcoma tissues and 5 osteosarcoma cell lines.MICA expression was examined in 66 paraffin-embedded osteosarcoma tissues and 6 paraffin-embedded normal bone tissues by immunohistochemistry,and MICA protein in 9 fresh osteosarcoma tissues was detected by Western blot too.MICA surface expression was estimated by flow cytometry.[Results] Nine of eleven (81.8%) osteosarcoma specimens and all of the five cell lines consistently expressed MICA mRNA.Up-regulation of MICA expression was found in osteosarcoma (34/66,51.6%),compared with normal bone tissues (0/6,0%).The cell lines Saos-2,MG63,and HOS showed positive surface MICA expression,while the U2OS and OS732 showed very limited expression.[Conclusion] MICA mRNA and protein predominantly expressed on osteosarcoma tissues and cell lines.

OBJECTIVETo observe serum contents of granulocyte-macrophage colony-stimulating factor (GM-CSF) and granulocyte colony-stimulating factor (G-CSF) in mice with marrow inhibition before and after acupuncture and moxibustion treatment, so as to discuss the molecular biological mechanisms of acupuncture and moxibustion on improving marrow inhibition and increasing white cells after chemotherapy.

METHODSEighty clean-grade male Kunming mice were selected and randomly divided into a normal group, a model group, an acupuncture group and a moxibustion group according to the weight, 20 cases in each one. Mice in the model group, acupuncture group and moxibustion group were injected with cyclophosphamide (CTX) to establish mice models of marrow inhibition, while mice in the normal group received intraperitoneal injection of 0.9% NaCl. Four hours after model establishment, mice in the acupuncture group and moxibustion group were treated with acupuncture or moxibustion at "Dazhui" (GV 14), "Geshu" (BL 17), "Shenshu" (BL 23) and "Zusanli" (ST 36), respectively. Mice in the normal group and model group were immobilized without any treatment. All the treatment was given once a day for consecutive 5 days. Mice blood samples were collected from caudal vein. With manual examination, the white blood cells in peripheral blood were measured on each day from model establishment to end of treatment. Enzyme linked immunosorbent assay (ELISA) method was used to measure the serum contents of GM-CSF and G-CSF 3 days and 5 days after treatment.

RESULTSCompared with the normal group, the white cells in the model group were all reduced at each time point (all P<0.05), and the serum contents of GM-CSF and G-CSF were significantly reduced (all P<0.05). Three days after treatment, compared with the model group, the white cells in the acupuncture group and moxibustion group were increased, and the difference in acupuncture group was significant (P<0.05); the serum contents of GM-CSF and G-CSF were significantly lifted (P<0.05). Four days after treatment, compared with the model group, the white cells in the acupuncture group and moxibustion group were increased (both P<0.05). Five days after treatment, compared with the model group, the white cells in the acupuncture group and moxibustion group were increased and close to the normal level; the serum contents of GM-CSF and G-CSF were significantly lifted (all P<0.05).

CONCLUSIONThrough increasing serum contents of GM-CSF and G-CSF in CTX mice, acupuncture and moxibustion could prompt maturation and proliferation of myeloid hematopoietic cells, which is benefit to the reconstruction of hematopoietic function and relieve the marrow inhibition caused by CTX, and thus lift peripheral white blood cells.
