Objective To investigate the effects of pioglitazone on serum leptin and adiponectin in polycystic ovary syndrome (PCOS) patients with insulin resistance (IR). Methods Thirty-five PCOS patients with IR were treated with pioglitazone 15mg/d for 12 weeks. The results of ovulation induction were observed. The changes of fasting plasma glucose (FPG), fasting serum insulin (FINS), serum levels of leptin, adiponectin, follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T) and blood fat were examined at the baseline and after the therapy by enzyme-linked immunosorbent assay (ELISA) and radioimmunoassay (RIA). Results After the treatment, the rate of ovulation per cycle was improved in 31 (88.5%) out of the 35 patients. After treatment, the level of serum leptin was decreased (P<0.05) while the level of serum adiponectin was increased (P<0.05). After 12 weeks'treatment, waist-to-hip ratio and F-G score were significantly decreased (P<0.05), BMI declined but without significant difference (P>0.05). The levels of LH, T, FINS, Homa-IR, total cholesterol, triglyceride and low density lipoprotein-cholesterol were significantly decreased (P<0.01, P<0.05), whereas the level of high density lipoprotein-cholesterol was significantly increased (P<0.01). No significant difference was seen in FSH and FPG following treatment (P>0.05). Conclusion Pioglitazone treatment can effectively improve PCOS with IR patients'clinical syndromes, insulin sensitivity, glucose and lipid metabolism at least partly through improving the profiles of leptin and adiponectin.

BACKGROUND: Chronic myeloid leukemia (CML) is characterized by the clonal expansion of hematopoietic stem cells. Without effective treat ment, individuals in the indolent, chronic phase (CP) of CML will undergo blast crisis (BC), the prognosis for which is poor. Therefore, it is important to clarify the mechanism underlying CML from a whole-genome perspec tive. OBJECTIVE: To investigate the gene expression profile of bone marrow mononuclear cells from CML with Applied Biosystems Expression Array System.DESIGN: Observation and controlled analysis.SETTING: Institute of Gene Engineering, Southern Medical University PARTICIPANTS: Samples of two cases of bone marrow (a chronic myeloid leukemia patient and a healthy person).METHODS: This experiment was conducted at the Institute of Gene Engineering, Southern Medical University from October 2004 to September 2005.The total RNAs were extracted and purified from bone marrow mononuclear cells derived from a CML patient and a healthy person. mRNAs were purified using an oligo (dT)-cellulose mRNA purification kits and labeled using reverse transcription, in vitro transcription (RT-IVT), then hybridized with microarray. Gene expression differentiation of the bone marrow mononuclear cells were examined by ABI 1700 Chemiluminescent Microarray Analyzer. Reproducibility of microarray results was assessed by comparing data sets obtained from the same sample and analyzed by two different arrays.MAIN OUTCOME MEASURES: ①Assessment of quality of total RNA and labled cRNA. ②Reproducibility of microarray. ③ Hybridization of array.④Results of semi-quantitative reverse transcription-polymerase chain reaction RESULTS: ①Using statistical data analysis tools, we identified 6 706 genes that were up- or down-regulated in CML patient compared with the healthy person. In these genes, we found that 17 genes were up-regulated while 51 genes were down-regulated among 68 genes closely related to CML. ②most differentially expressed genes in C/EBPalpha mediated path way and CD40L signaling pathway had reduced expression. ③Good repro ducibility of microarray was confirmed by analysis of correlation and detection concordance in technical replicates. The correlation coefficient of the detectable probe in technical replicates was 0.991 for the CML patient and 0.988 for the healthy person. ④The results of semi-quantitative RT-PCR experiments supported the reliability of our microarray analysis.CONCLUSION: By comparing expression patterns of CML with those of the healthy person, we identified a large number of genes that, were up- or down-regulated in CML patients. These data should provide useful information for finding candidate genes whose products might serve as molecular targets for treatment of CML patients.

Many Chinese medicinal materials are difficult to be distinguished in characters resulting in easy confusion. In the pa-per, the basic concepts of three groups of easily confused Chinese medicinal materials ( schisandrae chinensis fructus and schisandrae sphenantherae fructus, phellodendri cortex and phellodendri amurensis cortex, akebiae caulis and clematidis armandii caulis) were illus-trated and the development of verification methods were reviewed in the respect of modern instrumental analysis technology. With the improvement of analysis technology, the identification of Chinese medicinal materials relies on experimental data instead of artificial ex-perience, which makes it more objective and accurate.

Objective:To research the TLC identification method for Longdan Xiegan pills( honey pills) . Methods:TLC was used in the identification. The samples were extracted by 70% methanol with a heating reflux method, and then extracted by the agents with dif-ferent polarity, including petroleum ether, ethyl acetate and butanol. The petroleum ether part was detected by fluorescence at 365nm for Angelica sinensis, and 1% vanillin-sulfuric acid color reaction was used to detect Alisma orientale. The ethyl acetate part was determined by fluorescence at 365nm for Scutellaria baicalensis, and the butanol part was detected with chloroform-methanol-water (30∶12∶3) as the developing solvent for Bupleurum and Glycyrrhiza, and with acetone-ethyl acetate-water (6∶6∶1) as the developing solvent for gentiopi-croside, geniposide and liquiritin. Results:The developed TLC spots were clear with good separation, high specificity and promising re-producibility. Conclusion:The method can be exactly used in the qualitative identification and quality control of Longdan Xiegan pills ( honey pills) .
