OBJECTIVETo observe the intervention and mechanism of Qushi Huayu Recipe (QHR) on gene expression profiles in high lipid diet induced fatty liver rats.
METHODSFatty liver model was prepared in 20 male SD rats using single high fat diet (88% common forage +2% cholesterol +10% lard). Four weeks after modeling they were divided into the model group and the QHR group according to random digit table, 10 in each group. QHR (at 0. 93 g crude drug/100 g body weight) and distilled water was respectively to rats in the QHR group and the model group by gastrogavage while modeling, once per day. Meanwhile, 10 SD male rats were recruited in a normal group, administered with equal volume of distilled water by gastrogavage. At the end of week 8 all rats were sacrificed, and blood and livers were collected for subsequent analysis. Contents of liver triglyceride (TG) and free fatty acid (FFA) , activities of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected using biochemical assay. Pathological changes of liver tissue were observed using H&E and oil red O stain. Liver gene expressions were detected by Affymetrix gene expression profiles. Differentially expressed genes were compared between the QHR group and the model group, functions of differentially expressed genes and signal pathways involved analyzed. Ten differentially expressed genes involved in glycolipid metabolism with fold change more than 2 were selected for verification by real-time PCR.
RESULTS(1) Compared with the normal group, contents of liver TG and FFA, and serum activities of ALT and AST obviously increased in the model group (P <0. 01). Compared with the model group, contents of liver TG and FFA, and activities of ALT and AST obviously decreased in the QHR group (P <0. 05, P <0. 01). QHR could reduce high fat induced fatty degeneration of liver cells , alleviate inflammation, and improve pathological changes of liver tissue. (2) Compared with the model group, there were 80 differentially expressed genes (with fold change > 2, P < 0.05) with clear functions and appointed gene names, including 44 up-regulated and 36 down-regulated genes. Eighty genes were involved in 27 signal pathways with statistical difference, including glycerolipid metabolism, adipocytokine signaling pathway, insulin signal pathway, drug metabolism signal pathway, etc (P < 0.05). (3) RT-PCR results of 10 glycolipids metabolism regulating genes such as Gk, Scd1, Gpat2, G6pc, Irs1, and so on showed that all RT-PCR genes were completely coincide with up-regulated or down-regulated tendency in results of gene chips. 80% genes had approximate fold change.
CONCLUSIONQHR could regulate gene expressions related to fat metabolism, carbohydrate metabolism, anti-lipid peroxidation, and drug metabolism in high fat diet induced fatty liver rats, and its comprehensive pharmacological actions could be manifested.

OBJECTIVETo establish discriminant functions of diarrhea-predominant irritable bowel syndrome (IBS-D) by studying it from quantitative diagnosis angle, hoping to reduce interference of subjective factors in diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.
METHODSA Chinese medical clinical epidemiological survey was carried out in 439 IBS-D patients using Clinical Information Collection Table of IBS. Initial syndromes were obtained by cluster analysis. They were analyzed using step-by-step discrimination by taking information of four Chinese medical diagnostic methods and serum brain-gut peptides (BGP) as variables.
RESULTSClustering results were Gan stagnation Pi deficiency syndrome (GSPDS), Pi-Wei weakness syndrome (PWWS), Gan stagnation qi stasis syndrome (GSQSS), Pi-Shen yang deficiency syndrome (PSYDS), Pi-Wei damp-heat syndrome (PWDHS), cold-damp disturbing Pi syndrome (CDDPS). Of them, GSPDS was mostly often seen with effective percentage of 34. 2%, while CDDPS was the least often seen with effective percentage of 5.5%. A total of 5 discriminant functions for GSPDS, PWWS, GSQSS, PSYDS, and PWDHS were obtained by step-by-step dis- crimination method. The retrospective misjudgment rate was 4.1% (16/390), while the cross-validation misjudgment rate was 15.4% (60/390).
CONCLUSIONThe establishment of discriminant functions is of value in objectively diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.

OBJECTIVEThe purpose of this study was to assess the feasibility of fluorescent 2-deoxyglucose analog, 2-[N-(7-nitrobenz-2-oxa-1, 3-diaxol-4-yl)amino]-2-deoxyglucose (2-NBDG), that could be taken up by breast cancer cells highly expressing glucose transporter 1 (GLUT-1). The purpose of this study was to clarify if a fluorescent 2-deoxyglucose analog, 2-[N-(7-nitrobenz-2-oxa-1, 3-diaxol-4-yl)amino]-2-deoxyglucose (2-NBDG), can be taken up by breast cancer cells highly expressing glucose transporter 1 (GLUT-1), and to assess whether it can be used as a targeting imaging agent.
METHODSThe expressions of GLUT-1 mRNA and protein in breast cancer MDA-MB-231 cells were detected by RT-PCR and immunohistochemistry, respectively. The difference of GLUT-1 protein expression between breast cancer MDA-MB-231 cells and MCF-7 cells was compared by Western blot. Secondly, MDA-MB-231 cells which were grown in 6-well plates were incubated with 2-NBDG, and the result of 2-NBDG uptake was analyzed by fluorescence microscopy and flow cytometry. The difference of 2-NBDG absorption in MDA-MB-231 and MCF-7 cells was compared by flow cytometry.
RESULTSThe results of RT-PCR and immunohistochemistry confirmed that MDA-MB-231 cells highly expressed GLUT-1. Furthermore, Western blot revealed that GLUT-1 expression of MDA-MB-231 cells (0.946 ± 0.007) was higher than that in the MCF-7 cells (0.833 ± 0.010). Fluorescence microscopic and flow cytometric analysis showed that 2-NBDG was uptaken rapidly by MDA-MB-231 cells. Addition of 50 mmol/L D-glucose to the media with 2-NBDG reduced its uptake by 46.0%. Moreover, flow cytometry indicated that the fluorescence intensity of MDA-MB-231 cells (25.10 ± 0.57) was higher than that of MCF-7 cells (10.12 ± 0.62) when incubated with 2-NBDG for 20 minutes.
CONCLUSIONThe preliminary data clearly demonstrate that 2-NBDG is taken up and accumulated in breast cancer cells that highly express GLUT-1, and may be used as an optical probe for glucose uptake in hypermetabolic malignant cells.

Aromatic traditional Chinese medicines have a long history in China, with wide varieties. Volatile oils are active ingredients extracted from aromatic herbal medicines, which usually contain tens or hundreds of ingredients, with many biological activities. Therefore, volatile oils are often used in combined prescriptions and made into various efficient preparations for oral administration or external use. Based on the sources from the database of Newly Edited National Chinese Traditional Patent Medicines (the second edition), the author selected 266 Chinese patent medicines containing volatile oils in this paper, and then established an information sheet covering such items as name, dosage, dosage form, specification and usage, and main functions. Subsequently, on the basis of the multidisciplinary knowledge of pharmaceutics, traditional Chinese pharmacology and basic theory of traditional Chinese medicine, efforts were also made in the statistics of the dosage form and usage, variety of volatile oils and main functions, as well as the status analysis on volatile oils in terms of the dosage form development, prescription development, drug instruction and quality control, in order to lay a foundation for the further exploration of the market development situations of volatile oils and the future development orientation.

The changes of kernel nutritive components and seed vigor in F1 seeds of sh2 sweet corn during seed development stage were investigated and the relationships between them were analyzed by time series regression (TSR) analysis. The results show that total soluble sugar and reducing sugar contents gradually declined, while starch and soluble protein contents increased throughout the seed development stages. Germination percentage, energy of germination, germination index and vigor index gradually increased along with seed development and reached the highest levels at 38 d after pollination (DAP). The TSR showed that, during 14 to 42 DAP, total soluble sugar content was independent of the vigor parameters determined in present experiment, while the reducing sugar content had a significant effect on seed vigor. TSR equations between seed reducing sugar and seed vigor were also developed. There were negative correlations between the seed reducing sugar content and the germination percentage, energy of germination, germination index and vigor index, respectively. It is suggested that the seed germination, energy of germination, germination index and vigor index could be predicted by the content of reducing sugar in sweet corn seeds during seed development stages.

OBJECTIVETo determine the involvement of FasL/Fas pathway in apoptosis of J774A.1 cells induced by Leptospira interrogans.
METHODSThe cell infection model was established with mouse monocyte-macrophage J774A.1 cells infected by L.interrogans serogroup Icterohaemorrhagiae serovar lai strain 56601. The morphological characteristics of apoptotic J774A.1 cells were observed by DAPI staining method, and the apoptosis rate was quantitatively determined by flow cytometry. FasL neutralizing antibody was applied to block the apoptosis. Expression of FasL or Fas in the L.interrogans strain 56601-infected J774A.1 cells was detected by flow cytometry using PE-conjugated monoclonal antibody.
RESULTChromatin condensation and marginalization were found in J774A.1 cells infected by L.interrogans strain 56601 for 4 h, which became more predominant for 24 h and karyorrhexis was present in some cells. When J774A.1 cells were infected for 4 h and 24 h, the apoptosis rates were 53.6% and 64.31%, respectively. However, the apoptosis rates were decreased to 10.27% and 15.9% after the cells were pre-treated with FasL neutralizing antibody. When J774A.1 cells were infected for 4 h and 24 h, FasL expression rates were increased to 21.69% and 65.70% from that of 4.19% before infection, and Fas expression rates were risen to 91.96% and 88.01% from that of 12.88% before infection.
CONCLUSIONInducement of cell apoptosis is an important mechanism of L.interrogans strain 56601 injuring J774A.1 cells. The strain of L.interrogans is able to up-regulate FasL/Fas expression levels of host cells and induce apoptosis of the cells via FasL/Fas pathway.

BACKGROUND AND OBJECTIVEAnemia can not only reduce the quality of life of patients with cancer, but also affect their survival. This study was to investigate the prognostic value of hemoglobin (Hb) level in patients with nasopharyngeal carcinoma (NPC) treated with radiotherapy.
METHODSClinical data of 520 NPC patients received definitive radiotherapy between 2000 and 2002 at Sun Yat sen University Cancer Center were analyzed. Patients were stratified into normal Hb level and anemia groups according to their Hb levels before, during, and after radiation. Anemia was defined according to World Health Organization criteria as Hb level < 130 g/L in men and < 120 g/L in women. Hb continuous decrease group and non decrease group were defined according to Hb changes in the patients during radiotherapy. Loco regional recurrence free survival (LRFS) and overall survival (OS) rates were estimated using the Kaplan Meier method. Multivariate analysis was performed using the Cox model to analyze the prognostic factors.
RESULTSBefore radiation, the 5 year LRFS rates were 60.9% in anemia group and 63.9% in normal Hb level group (P = 0.337); the 5 year OS rates were 65.2% and 71.0%, respectively (P = 0.299). During radiation, the 5 year LRFS rates were 56.7% in anemia group and 67.9% in normal Hb level group (P = 0.013); the 5 year OS rates were 61.0% and 75.9%, respectively (P = 0.001). After radiation, the 5 year LRFS rates were 59.6% in anemia group and 64.9% in normal Hb level group (P = 0.169); the 5 year OS rates were 65.0% and 71.9%, respectively (P = 0.090). The 5 year LRFS and OS rates were significantly lower in Hb continuous decrease group than in Hb non decrease group (59.1% vs. 69.3%, P = 0.032; 66.2% vs. 76.4%, P=0.011). Multivariate analysis showed that the continuous decrease of Hb was an independent prognostic factor for OS.
CONCLUSIONThe change in Hb level during radiotherapy is an important prognostic factor affecting the OS of NPC patients.
