Metabolic changes are recognized as one of the hallmarks of cancer cells. Previous studies have shown that hypoxia can change the glucose metabolism of cancer cells. However, the mechanisms still need to be studied in detail. In this study, by using RNA-Sequencing (RNA-seq) and bioinformatics analysis, we found that there is a significant change in the expression of 334 genes in BT549 cells and 215 genes in MDA-MB-231 cells induced by hypoxia at the mRNA level. Most of these genes were associated with glucose metabolism. RNA-seq data, Western blot, enzyme activity assays, and metabolite quantification experiments showed that the glucose uptake increased by elevating the expression of glucose transporter protein 1 (GLUT1) in BT549 cells and GLUT1 and GLUT3 in MDA-MB-231 cells induced by hypoxia. Hypoxia promotes glycolysis by increasing the expression of at least one isozyme or enzyme protein subunit of the enzymes that catalyze the each reaction in the glycolysis pathway, as well as the regulatory enzymes 6-phosphofructo-2-kinase/fructose-2, 6-biphosphatase 3 (PFKFB3) and 4 (PFKFB4) isozymes. Hypoxia increases the expression of pyruvate dehydrogenase kinase 1 (PDK1) and PDK3 and reduces the expression of isocitrate dehydrogenase 3(IDH3), succinate dehydrogenase subunit B(SDHB) and D(SDHD) to reduce the aerobic oxidation pathway. The expression of glucose-6-phosphate dehydrogenase (G6PD) and glycogen synthase was significantly increased to promote the pentose phosphate pathway and glycogen synthesis pathway. The mRNA levels of enzyme genes had no significant difference in gluconeogenesis and glycogenolysis. The breast cancer database suggests that the mRNA levels of the glucose metabolism enzymes were consistent in vivo and in vitro. Hypoxia regulates the reprogramming of glucose metabolism by altering the gene expression of isozymes or subunits of these enzymes. The study comprehensively analyzed the effects of hypoxia on the expression of all enzyme genes and major regulatory enzymes in six glucose metabolism pathways and provides an understanding of glucose metabolism in cancer cells under a hypoxia environment.

Pre-formulation physicochemical properties of the component-based Chinese medicine of Qinqi Fengshi Fang were investigated to provide a research basis for the design of the dosage form for component-based Chinese medicine of Qinqi Fengshi Fang. The macroporous resin adsorption and refining technology was used to prepare the total glycosides extract of Gentianae Macrophyllae Radix, Panacis Majoris Rhizome and Corni Fructus respectively in the prescription of Qinqi Fengshi Fang. Their physicochemical properties were investigated, including solubility, wettability, hygroscopicity, equilibrium solubility, oil-water partition coefficient, and stability. The results showed that the total glycosides of Gentianae Macrophyllae Radix, Panacis Majoris Rhizome and Corni Fructus all had good solubility and wettability. The solubility index of each total glycoside component was greater than 85%, and the water absorption index was greater than 50%. In the range of pH 2.0-7.4, the equilibrium solubility of three kinds of total glycosides all increased with the increase of pH, showing a consistent change trend of solubility. The hydrophilicity was also suitable and similar. Overall, three kinds of total glycosides showed good stability, but strong hygroscopicity. The degree of hygroscopicity was as follows: total glycosides of Gen-tianae Macrophyllae Radix > total glycosides of Corni Fructus > total glycosides of Panacis Majoris Rhizome. Therefore, the hygroscopi-city needed to be considered in the preparation of the component-based Chinese medicine of Qinqi Fengshi Fang. The excipients and packaging materials can be properly selected to reduce the hygroscopicity of the preparation. This study provides a reference for the dosage form design of the component-based Chinese medicine of Qinqi Fengshi Fang.

To explore the effects of shading and the expression of key enzyme genes on the synthesis and accumulation of Panax japonicus var. major saponins, different shading treatments (0%, 30%,50%) of potted P. japonicus var. major were used as test materials, the expression of three key enzyme genes(CAS,DS,-AS) of leaves and rhizomes in different growth periods of P. japonicus var. major was determined by real-time quantitative PCR, the content of total saponins was determined by ultraviolet spectrophotometry. The results indicated that, in flowering stage, CAS,DS,-AS were highly expressed in the aerial parts of P. japonicus var. major, 30% shading treatment significantly inhibited the expression of CAS in leaves and promoted the expression of DS and -AS in stems, leaves and flowers, it was speculated that the main part of saponin synthesis was leaf in this stage. Both the expression levels of DS and -AS and changes in the content of total saponins in leaves showed a tendency of low-high-low throughout the growth cycle, correlation coefficient analysis showed that there was a positive correlation between them. Compared with control, the expression levels of DS and -AS and the content of total saponins were greatly enhanced under shading treatment, 30% shading treatment significantly promoted the accumulation of total saponins. Therefore, it is suggested that 30% shading treatment should be applied to the artificial cultivation of P. japonicus var. major, which is beneficial to the accumulation and quality improvement of saponins.

OBJECTIVETo investigate clinical effects of auricular acupoint (AA) in the treatment of analgesia during perioperative period in total hip arthroplasty.

METHODSFrom March 2008 to August 2010, 60 patients with late osteonecrosis of the femoral head were treated by total hip arthroplasty and randomly divided into auricular acupuncture (AA) group and control group, 30 patients in each group. There were 11 males and 19 females in the AA group,with an average age of (60.93 +/- 5.90) years; the patients were treated with auricular acupuncture on the point of Shenmen, Subcortex, Kidney and hip joint for four times a week. There were 12 males and 18 females in control group, with an average age of (59.87 +/- 6.21) years; while the patients without auricular acupuncture. VAS score was used to evaluat the degree of pain; Harris score was used to evaluat the function of hip joint. All patients received patient controlled analgesia pump (PCA) for 48 hours after surgery (400 ml liquids were in PCA pump, including 800 mg tramadol and 0.8 mg fentanyl). The dosage of liquids and adverse reaction of PCA pump in different time were recorded.

RESULTSThe VAS score on the 3rd, 4th, 5th and 7th day separately was (3.61 +/- 0.29), (3.59 +/- 0.30), (2.97 +/- 0.26), (2.29 +/- 0.45), and lower than control group, which separately was (4.19 +/- 0.28), (4.00 +/- 0.31), (3.15 +/- 0.29), (2.83 +/- 0.31). The dosage of PCA in AA group separately was (72.27 +/- 8.06), (60.40 +/- 8.16), (44.13 +/- 4.75), (40.40 +/- 3.69), and less than control group, which was (86.27 +/- 8.51), (73.87 +/- 8.32), (54.53 +/- 5.20), (44.67 +/- 6.31) on the time of 0-12, 12-24, 24-36 h and 36-48 h after surgery. During the using of PCA, nausea and vomiting occurred in 5 cases, less than control group (21 cases). Harris score in AA group (78.90 +/- 5.14) was higher than control group (73.37 +/- 5.99) 2 weeks after operation.
