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.

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.

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 evaluate the influence Qizhu decoction on VEGF and its receptor KDR/flk-1 protein expression in MGC803 cell. Methods Four groups of MGC-803 Cells were established, and intervened with blank control, DMSO control, high dose Qizhu decoction, and low dose Qizhu decoction respectively. VEGF and KDR/flk-1 protein were detected by flow cytometry and western bloting. Results The value of VEGF expression was 120.0±10.8, 116.8±14.7, 95.0±12.5, and 108.4±13.5 respectively in each group. The difference between high dosage Qizhu decoction group and the bland control group was significant. Value of KDR/flk-1 were 10.4±3.5, 9.0±3.4, 6.8±2.3, and 6.8±3.5 in each group respectively. There was no significant difference among these 4 groups. The grayseale values of VEGF expression was 14.45±4.61, 12.32±3.27, 2.58±0.84, and 3.45±1.12 in each group respectively. There was significant difference between the QiZhu groups and the blank control group. Meanwhile grayseale values of KDR/flk-1 expression were 3.87±1.05, 3.55±1.32, 3.62±1.01, and 3.73±0.88 in each group respectively, showing no significant difference among 4 groups. Conclusion Rough extraction of QiZhu decoction down-regulated the protein expression of VEGF, but had no effects on the expression of KDR/flk-1.
