A quantitative method using ultrahigh-performance liquid chromatography was established to simultaneously determine ten ginsenoside active ingredients including ginsenoside Rg6, F4, Rk3, Rh4, 20(S) -Rg3, 20(R) -Rg3, Rk1, Rg5, 20(S)-Rh2 and 20(R)-Rh2 in steamed notoginseng. The ten ginsenosides of steamed notoginseng with different head numbers, parts, and steaming time were determined by this method. An Acquity BEH C18 chromatographic column (2.1 mm x 100 mm, 1.7 microm) was used to perform the determination, which was maintained at 35 degrees C throughout the analysis. Mobile phase was composed of water and acetonitrile with flow rate at 0.3 mL x min(-1) under gradient elution, and detection wavelength was set to 203 nm for monitoring the separation. The results demonstrate ginsenoside Rg6, F4, Rk3, Rh4, 20 (S)-Rg3, 20 (R) -Rg3, Rk1, Rg5, 20 (S)-Rh2 and 20(R) -Rh2 have shown good linearity (R2 > or = 0.999 8) within 0.46-115, 2.06-515, 1.632408, 3.216-804, 1.392-348, 1.4-350, 0.496-248, 3.012-1 506, 0.82-205 and 0.832-208 mg x L(-1), and their average recoveries were 97.00%, 97.96%, 98.86%, 95.27%, 98.67%, 98.02%, 95.53%, 96.63%, 99.57% and 103.6%, respectively. The proposed approach was quick and accurate and portrayed excellent repeatability and determination efficiency. The quality of steamed notoginseng was effectively controlled, which served as a foundation for establishing a normalized processing technique and quality standard for ensuring the reliability and consistency of its clinical efficacy.

Astragalus polysaccharides was lounded to 4-(2-aminoethylphenol), followed by labeling the APS-Tyr with fluorescein-5-isothiocyanate (FITC) at the secondary amino group. The absorption enhancement effects of low molecular weight chitosan and protamine on astragalus polysaccharides were evaluated via Caco-2 cell culture model. The results show that the fluorecent labeling compound has good stability and high sensitivity. On the other hand low molecular weight chitosan and protamine also can promoted absorption of the astragalus polysaccharides without any cytotoxity, and the absorption increase was more significant with increasing the amount of low molecular weight chitosan and protamine. At the same time, the low molecular weight chitosan has slightly better effect. The transepithelial electric resistance (TEER) of Caco-2 cells show that absorption enhancers could improve its membrane transport permeability by opening tight junctions between cells and increasing the cell membrane fluidity.

OBJECTIVETo observe the therapeutic efficacy of Dangfei Liganning Tablet (DLT) in the treatment of antipsychotics induced mild hepatic damage.
METHODSTotally 80 mental inpatients with antipsychotics induced mild liver injury were randomly assigned to two groups, the treatment group (40 cases) and the control group (40 cases). Patients in the treatment group took DLT, two tablets each time, three times per day, while those in the control group took Liver-protecting Tablet (LT), four tablets each time, three times per day. The treatment course was 4 weeks for all. Changes of glutamic-pyruvic transaminase (ALT) and glutamic-oxalacetic transaminase (AST) were observed before treatment, week 1, 2, and 4 after treatment. The therapeutic efficacy was compared between the two groups.
RESULTSCompared with the former time point, ALT and AST gradually decreased in the two groups at week 1, 2, and 4 (P <0. 05). The cured rate was 72. 5% and the total effective rate was 97. 5% in the treatment group. They were 62. 5% and 90. 0% respectively in the control group. There was no statistical difference in the two indices between the two group (P >0.05). No obvious adverse reaction occurred in the two groups.
CONCLUSIONDLT could treat antipsychotics induced mild hepatic damage in a safe and effective way.

Objective To analyze the risk factors of hypoxemia after coronary artery bypasses grafting (CABG) along with cardiopulmonary bypasses and to understand the regular pattern and characteristics of hypoxemia after CABG. Methods The risk factors of hypoxemia were studied by one way analysis and multivariate logistic regression analysis in 86 patients with hypoxemia after CABG along with cardiopulmonary bypass. Results One way analysis indicated that hypoxemia after CABG along with cardiopulmonary bypass was related to senility ( ≥ 65 years ), smoking history, diabetes mellitus, chronic obstructive pulmonary disease ( COPD), left ventricular ejection fraction ( LVEF < 45 % ), obesity before operation, transfusion ( ≥ 1000 ml );multivariate analysis indicated that pulmonary dysfunction before operation, longer extracorporeal circulation time ( ≥2 h), hypoalbuminemia and pulmonary infection were independent risk factors of hypoxemia after CABG along with cardiopulmonary bypass. Conclusion Multiple risk factors contributed to hypoxemia after CABG along with cardiopulmonary bypass. Increase the awareness of risk factors of perioperative hypoxemia may guide the prevention and treatment, even alleviate or avoid the hypoxemia postoperatively.

BACKGROUND: There still is rarely report about the effect of glycosylphosphatidilinoditol-specific phospholipase D (GPI-PLD) on the adhesion function of leukemic cells through screening Medline and CNKI databases.OBJECTIVE: To observe the effect of GPI-PLD on the adhesion function of bone marrow mononuclear cells separated from myeloid leukemia patients, and to investigate the related mechanism. DESIGN, TIME AND SETTING: This study addressing cytology in vitro was conducted at the Hematological Laboratory of Xiangya Hospital from January to June 2004.MATERIALS: Bone marrow was collected from myeloid leukemia patients at the Department of Hematology, Xiangya Hospital, China.METHODS: The GPI-PLD activity of bone marrow mononuclear cells separated from myeloid leukemia patients was measured by using GPI-anchored placental alkaline phosphatase as substrate and Triton-X114 partition. By use of 1,10-phenanthroline, the activity of GPI-PLD was inhibited, the experiment was divided into 2 groups: treatment group adding phenanthroline to achieve a final concentration of 1 mmol/L, while control group adding the same amount of phosphate buffered saline. The adhesion rate to the fibronectin and CD24 expression of these cells were measured by MTT and immunohistochemical method, respectively.MAIN OUTCOME MEASURES: GPI-PLD activity of myeloid leukemic cells, cell adhesion rate, CD24 expression were all measured. RESULTS: The GPI-PLD activity of bone marrow mononuclear cells separated from myeloid leukemia patients was inhibited significantly after these cells were treated by 1 mmol/L 1,10-phenanthroline for 5 hours compared with control groups [(5.40±2.96)%, (42.08±7.21)%, P < 0.01]. At the same time, the adhesion rate of these cells were increased after the GPI-PLD activity was inhibited [(61.19±29.14)%, (49.78±26.73)%, P < 0.01], and the CD24 expression was also up-regulated [(18.5±11.14)%, (16.02±9.68), P < 0.01].CONCLUSION: The adhesion rate of bone marrow mononuclear cells separated from myeloid leukemia patients can be promoted by inhibiting GPI-PLD activity. At the same time, the CD24 expression of GPI-anchored proteins on bone marrow mononuclear cells is improved.
