Objective To analyze the constitutes of essential oil form Nervilia fordii. Methods GC-MS was used to analyze the essential oil. The relative content of each component was determined by area normalization. Results Fifty-five kinds of constitutes were identified,accounting 97.1 %of total contents. The content of 2-Pentadecanone,6,10,14-trimethyl is the highest,being 13.55 %,which had also been found in the same family. Conclusion 2-Pentadecanone,6,10,14-trimethyl can be used for the identification of the same family.

Xiaozhenjie (Miraculous Pivot Chapter 3: Annotation of Fine Needle) is the earliest annotation of Jiuzhen Shieryuan (Miraculous Pivot Chapter 1: Nine Needles and Twelve Yuan-Primary Acupoints). There are particularly 24 annotations of qi in the chapter. Based on the original literature, the styles of qi annotationsl were divided into three categories. By comparing with the original text, semantic features of qi annotations were reasoned. In reference to the understandings and notes of qi annotations given by the scholars of different dynasties, the origin of qi connotation in the ancient time was clarified so as to provide the historical evidence to the for-mation of this unique "qi language" and "qi worldview". It presents the instructive significance to understand and interpret "qi" for the scholars in the modern time.

The accurate annotation of ashi points depends on the understanding of ashi. The main reasons for the divergence of current three viewpoints on the annotation of ashi are the literature basis and its different interpretations. By conducting a comprehensive collection of ancient and modern literature and analyzing different interpretation methods, the original meaning of ashi is studied, so as to explain the understanding of ashi points and ashi method.

Cohesion is a degree that reflects the mutual attractions among the members in a group and pays attention to the status of members.It is association and distillation of all members'will and behavior extension in a group.The intensity of the group cohesion is the important symbol whether a group is competitive or not,and it plays an important role in the survival and the development of a group.This paper starts with the group cohesions of teachers in higher institutions and analyses the factors that affect the group cohesion in higher institution,On this basis,the paper puts forward the tactics in improving the group cohesion of higher institution.

AIM:To compare the efficacy of three types of eye care (artificial tear, moist chamber and polyethylene covers) for preventing exposure keratopathy in intensive care patients.METHODS: Intensive Care Unit (ICU) patients were randomly divided to three treatment groups, including artificial tear group(29 cases), moist chamber group (27 cases) and polyethylene covers group (28 cases). Patients in artificial tear group received two drops of carboxymethylcellulose dropped to each eye every 2 hours. The moist chamber and polyethylene covers groups were changed every 12 hours or as needed if they became unclean or torn. Corneal fluorescein stain was performed daily.RESULTS:No one in the polyethylene covers group and one case(4%) in the moist chamber group had exposure keratopathy compared to 8 cases (28%) in the artificial tear group. There were statistical significance differences between both artificial tear group and moist chamber group (P=0.02), artificial tear group and polyethylene covers group (P=0.003). Everyday time of eye care in the artificial tear group, the moist chamber group and the polyethylene covers group was respectively 26.69±2.39, 35.33±2.63 and 7.48±0.87 minutes. Everyday time of eye care in the polyethylene covers group was statistically more time-saving than that in the artificial tear group (P<0.01) and the moist chamber group (P<0.01). CONCLUSION: Polyethylene covers are more effective and time-saving in reducing the incidence of corneal damage in intensive care patients.

OBJECTIVE: To investigate the uptake and transport properties of micelles across Madin Darby canine kidney (MD-CK) cells. METHODS: Coumarin 6 loaded PEG-PLA (PEG3000-PLA3000) micelles were prepared by solvent evaporation method, and the HPLC determination method of coumarin 6 was constructed. Competition uptake of blank micelles with coumarin 6 micelles was studied. Temperature and inhibitors effect on transport of micelles across MDCK cell monolayer were studied, the concentration of Ca and EGTA were also studied. RESULTS: Coumarin 6 micelles could be internalized into cells very quickly, and the uptake of micelles could be inhibited by blank micelles. The transport of micelles was affected by temperature and inhibitors, which means that this process is an active and energy-dependent process. The concentration of Ca2+ and EGTA could affect the transport of the micelles, which means micelles could transport across the cell monolayer via paracellular pathway. The amount of transported coumarin 6 micelles was rather limited compared with coumarin 6 micelles added to the apical side. CONCLUSION: Micelles transport across MDCK cell monolayer via both paracellular and transcellular pathway at the same time.

Objective To improve the hardware of a medical radioisotope dose calibration system base on LabVIEW platform.Methods Hiish performance voltage-frequency-converter VFC32 was applied to realize hardware circuit design of medical radioisotope dose calibrator,and the function of the circuit wag analyzed.The output voltage signal from the calibrator ionization chamber was processed by the designed circuit.The output frequency signal from the circuit was obtained by USB-6009 DAQ and was then processed by virtual instrument designed using LabVIEW 8.0.Results Experimental data graphs indicated that the improved system had a better linearity in the low and medium frequency band.Conclusion The redesigned radioisotope dose calibrator has advantages in improving measuring accuracy,measuring range,feeble-minded detection limit and so on.

Objective To investigate the imbalance of Th1/Th2 cell response in patients with systemic lupus erythematosus (SLE) combined with coronary heart disease .Methods SLE patients ,SLE patients with coronary heart disease and healthy con-trols were enrolled and blood samples were collected .T-bet/GATA-3 ,the transcription factors of Th1/Th2 cells ,were detected by real-time PCR ;the intracellular cytokines IFN-γ and IL-4 in CD4 + T cells were stained by fluorescent antibodies and detected by flow cytometry ;the level of serum IFN-γ and IL-4 were detected by ELISA .Results Comparing with healthy control group ,the ex-pression level of Th1 transcription factor T-bet ,the introcellular secretion of IFN-γ in CD4 + T cells and the serum IFN-γ were all decreased in non-coronary heart disease patients with SLE( P < 0 .05) .Comparing with non-coronary heart disease patients with SLE or healthy control group ,the expression level of Th1 transcription factor T-bet ,the introcellular secretion of IFN-γ in CD4 + T cells and the serum IFN-γ were all increased in patients with SLE combined coronary heart disease(P< 0 .05) ;while the expression level of Th2 transcription factor GATA-3 ,the introcellular secretion of IL-4 in CD4 + T cells and the serum IL-4 were all decreased in patients with SLE combined coronary heart disease(P< 0 .05) .Conclusion There were imbalance towards Th1 cell response in patients with SLE combined coronary heart disease ,which may related to the occurrence and development of disease .
