The brown slime inside pipeline of the polluted mineral waters well was analyzed. It was confirmed that the brown slime was a biofilm formed mainly by growth of bacteria contaminant, using microscope analysis. After treated with HCl, the brown crystals and mycelioid matter presented in slimes disappeared. It was verified these were metal deposits. The samples produced Prussia blue deposits by dropping K 4Fe(CN) 6 and HCl, which proved that the metal deposits were iron compound. Also it was believed the biofilm was produced by growth of iron bacteria, mixed with deposits of iron compound. The iron bacteria have been isolated from the slimes and cultured in the laboratory. The colony on agar plate also produced Prussia blue deposits after treated with K 4Fe(CN) 6 and HCl. The cells form of pure culture was the same as that in the samples by electronmicroscope analysis. Therefore, It indicated that the bacteria on biofilm inside pipeline were iron bacteria mainly.

7.Fluorimetric analysis of camptothecin in Chinese herbal medicine common Camptotheca fruit.
Acta Pharmaceutica Sinica 2012;47(10):1370-1374
Three-dimensional (3D) fluorescence spectra and thin layer fluorescence chromatogram of common Camptotheca fruit (CCF) crude drug, camptothecin (CPT) and 10-hydroxycamptothecin (HCPT) have been studied, and a novel fluorimetric method for determination of CPT in CCF crude drug has been established. In 3D fluorescence spectra, CPT presented 3 fluorescence peaks with excitation wavelengths lambdaex of 215, 255 and 365 nm, separately, and all peaks with emission wavelength lambdaem of 430 nm. HCPT presented 4 fluorescence peaks with lambdaex of 220, 265, 325 and 375 nm, separately, and all peaks with lambdaem of 555 nm. The fluorescence of CPT is much stronger than that of HCPT. Comparison of 3D fluorescence spectra and analysis of thin layer fluorescence chromatogram revealed that the main fluorescent component of CCF is CPT. HCPT and other components basically do not interfere with the fluorescence of CPT. Under the condition of pH 3.0-6.7, CCF aqueous solution can produce strong and steady fluorescence. Using methanol as solvent, the extracting solution of CCF was prepared, and diluted properly with water, then measured fluorescence intensity at lambdaex/lambdaem = 365/430 nm to determine the content of CPT. A linear calibration curve covered the concentration range 0.002 35-0.235 microg x mL(-1). The regression equation was IF = 9 + 30,844 c, with correlation coefficient r = 0.999 (n=9). The method has been applied to the analysis of CPT in a CCF sample, with a result of 0.127% and a spiked recovery rate of 102%. The reliability of the method has been verified by a thin layer chromatography-fluorescence scanning method. Experimental results demonstrated that this method can be used for quality evaluation of CCF crude drug.

ObjectiveTo investigate the efficacy of laparoscopic hepatectomy for regional hepatolithiasis.MethodsThe clinical data of 81 patients with regional hepatolithiasis who received laparoscopic hepatectomy at the Southwest Hospital from March 2007 to March 2011 were retrospectively analyzed.Based on the classification of the Guideline for the diagnosis and treatment of hepatolithiasis 2007 version and indications for open surgery,hepatic lobes with calculi,biliary stricture or dilated bile ducts were resected laparoscopically after preoperative examination.Bile ducts of the remnant hepatic lobes were explored using fiber choledochoscope or electronic choledochoscope for the prevention of residual stones. Results Laparoscopic hepatectomy was successfully performed on 72 patients,and the other 9 patients were converted to open surgery. Left lateral lobectomy ( segments Ⅱ,Ⅲ ) was performed on 20 patients,left hemihepatectomy ( segments Ⅱ,Ⅲ,Ⅳ ) on 30 patients,right posterior lobectomy ( segments Ⅵ,Ⅶ ) on 11 patients,right anterior lobectomy ( segments Ⅴ,Ⅷ ) on 6patients,right hemihepateetomy (segments Ⅴ,Ⅵ,Ⅶ,Ⅷ ) on 9 patients,hepatic Ⅲ segmentectomy on 2 patients and hepatic Ⅵ segmentectomy on 3 patients.Gallbladders were resected,and intermittent portal triad clamping was performed on 15 patients.Hepateetomy combined with biliary exploration and stone removal was performed on 57 patients.The mean operation time and operative blood loss were (328 ± 80)minutes and (451 ±288) ml,respectively.No operative mortality was observed.Sixteen patients had postoperative complications,including pulmonary infection in 2 patients,pleural effusion in 4 patients,encapsulated effusion in the resection margin in 6 patients,abdominal infection and abscess in 2 patients and wound infection in 2 patients.Of the 16patients with complications,9 were cured by medicine,6 by pleural or abdominal drainage and 1 by wound debridement.The mean duration of hospital stay was ( 13 + 6)days.The intraoperative stone clearance rate was 96% (69/72),and the residual stone in 3 patients were removed by choledochoscopy.Sixty-nine patients were followed up for 7-55 months,7 patients had symptoms of cholangitis and 2 patients had common bile duct stone recurrence.ConclusionsLaparoscopie hepatectomy is sate and effective for regional hepatolithiasis.Accurate positioning of the stones and lesions pre- and intra-operatively,reasonable designing of the parenchymal transection plane,and anatomical liver resection are the key points for achiving good therapeutic effects.
