The strain Streptomyces sp.,nominated IMB-14,was isolated from the soil sample of WuDang Mountain by the method of cellulose ester membrane filter.The studies on antibiotic activities,morphological characteristics,cultural characteristics,physiological characteristics,16S rDNA sequence analysis and the metabolite of strain IMB-14 showed that the strain IMB-14 was accordance with Streptomyces xanthoci-dicus.The study on the isolation and identification of strain Streptomyces xanthocidicus establishes a foundation on screening of novel antibacterial and antitumor agents.

BACKGROUND: Paraquat (PQ) is a world-wide used herbicide and also a type of common poison for suicide and accidental poisoning. Numerous studies have proved that the concentration of serum PQ plays an important role in prognosis. Spectrophotometry, including common spectrophotometry and second-derivative spectrophotometry, is commonly used for PQ detection in primary hospitals. So far, lack of systematic research on the reliability of the method and the correlation between clinical features of patients with PQ poisoning and the test results has restricted the clinical use of spectrophotometry. This study aimed to evaluate the reliability and value of spectrophotometry in detecting the concentration of serum PQ. METHODS: The wavelengths for detecting the concentration of serum PQ by common and second-derivative spectrophotometry were determined. Second-derivative spectrophotometry was applied to detect the concentration of serum PQ. The linear range and precision for detection of PQ concentration by this method were confirmed. The concentration of serum PQ shown by second-derivative spectrophotometry and HPLC were compared in 8 patients with PQ poisoning. Altogether 21 patients with acute poisoning 4 hours after PQ ingestion treated in the period of October 2008 to September 2010 were retrospectively reviewed. The patients were divided into higher and lower than 1.8 μg/mL groups based on their concentrations of serum PQ measured by second-derivative spectrophotometry on admission. The severity of clinical manifestations between the two groups were analyzed with Student's t test or Fisher's exact test. RESULTS: The absorption peak of 257 nm could not be found when common spectrophotometry was used to detect the PQ concentration in serum. The calibration curve in the 0.4–8.0 μg/mL range for PQ concentration shown by second-derivative spectrophotometry obeyed Beer's law with r=0.996. The average recovery rates of PQ were within a range of 95.0％ to 99.5％, relative standard deviation (RSD) was within 1.35％ to 5.41％ (n=6), and the lower detection limit was 0.05 μg/mL. The PQ concentrations in serum of 8 patients with PQ poisoning shown by second-derivative spectrophotometry were consistent with the quantitative determinations by HPLC (r=0.995, P<0.0001). The survival rate was 22.2％ in patients whose PQ concentration in serum was more than 1.8 μg/mL, and the incidences of acidosis, oliguria and pneumomediastinum in these patients were 55.6％, 55.6％and 77.8％, respectively. These clinical manifestations were different significantly from those of the patients whose PQ concentration in serum was less than 1.8 μg/mL (P<0.05). CONCLUSIONS: For common spectrophotometry, the wavelength at 257 nm was not suitable for detecting serum PQ as no absorbance was shown. Second-derivative spectrophotometry was reliable for detecting serum paraquat concentration. Serum PQ concentration detected by second-derivative spectrophotometry could be used to predict the severity of clinical manifestations of patients with PQ poisoning, and PQ content higher than 1.8 μg/mL 4 hours after ingestion could be an important predictive factor for poor prognosis.

Objective To explore the effect of uremic serum on apoptosis in human umbilical vein endothelial cells(HUVECs) and the intervention by recombinant human erythropoietin(rhEPO) in this process.Methods From Dec.2008 to Apr.2009,10 uremic patients and 10 healthy volunteers were enrolled in this study.HUVECs were divided into 3 groups:control group(including 10% healthy serum medium),uremic group(including 10% uremic serum medium) and rhEPO treatment group(rhEPO at 5,10 or 15 U/ml was added to 10% uremic serum medium).After 24 hous's intervention,cell apoptosis was evaluated by TUNEL assay,and reactive oxygen species were detected by colorimetry.Results HUVECs apoptosis index and ROS level were higher in the presence of uremic serum than those of healthy serum(P
