The brown slime inside pipeline of the polluted mineral waters 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 cells 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.

Objective To evaluate the effect of TGF-β1 and IL-1β expression in serum on acute radiation-induced heart disease (RIHD) in patients with thoracic tumors.Methods Three-dimensional conformal radiotherapy (3D-CRT) or intensity modulated radiotherapy (IMRT) was delivered at 1.8-2.0 Gy,5 times per week to a total dose of 50-66 Gy to 44 patients with lung cancer and 10 patients with esophagus cancer.The target and organs at risk dose distribution were analyzed by 3-dimensiond treatment planning system.The expressions of TGF-β1 and IL-1β in serum were detected by enzyme linked immunosorbent assay before and at the end of the irradiation.The cardiac injury was evaluated by detecting the cmyocardium creatase,cardiac troponin I (cTnI),electrocardiogram and cardiac function before and at the end of the irradiation within 90 d.The acute RIHD was evaluated by the Common Terminology Criteria V 3.0 (NCI-CTCAE 3.0).The expressions of TGF-β1 and IL-1β in the serum of RIHD patients with thoracic tumors were analyzed.Results The expression of TGF-β1 in serum was (888.4 ± 41.1) μg/L before the irradiation and approached to (926.1 ± 23.1) μg/L at the end of the radiotherapy.The expression level of TGF-β1 in the serum of acute RIDH group was (900.6 ± 34.5) μg/L,higher than that of normal group [(865.7 ±47.0) μg/L,t =-2.646,P ＜0.05)].The acute RIDH was correlated with the expression level of TGF-β1 before irradiation and the difference before and at the end of irradiation (r =0.378,0.311,P ＜0.05).The IL-1β expression had no significant difference before and after irradiation.The expression of TGF-β1 in serum before and at the end of irradiation had positive correlation with the expression of IL-1β at the end of the irradiation (r =0.416,0.389,P ＜ 0.05).Conclusions The expression of TGF-β1 in the serum of patients with thoracic tumor increases after irradiation and correlated with the acute RIHD,but the expression of IL-1β in serum has no relationship with RIHD.TGF-β1 could induce the expression of IL-1β at the end of the irradiation.

AIM: To explore correlation,consistency and comfort between traditional tear film examination methods and Oculus Keratograph.METHODS: A retrospective study.Totally 101 cases (101 eyes) were diagnosed myopia and then accepted LASEK (laser epithelial keratomileusis).Non-invasive tear film break-up time(NIBUT),lower tear meniscus height(LTMH) were measured with Oculus Keratograph,fluorescein tear film break-up time(fl-BUT) and Schimer Ⅰ test (SⅠt) were performed on all cases.The correlations analysis between NIBUT and fl-BUT,LTMH and SⅠt were performed by Spearman rank correlation,consistency check between NIBUT and fl-BUT by Bland-Altman analysis.Visual analogue scale(VAS) was applied on evaluating the comfort of two kinds of examination methods.RESULTS: LTMH and SⅠt showed positive correlation (rs=0.346,P=0.001).NIBUT and fl-BUT showed positive correlation (rs=0.393,P=0.001),95% consistency limits range-9.62 to 14.18 in Bland-Altman Figure.There was significant difference between VAS of NIBUT and VAS of fl-BUT(z=-2.324,P=0.020).There was significant difference between VAS of LTMH and VAS of SⅠt (z=-8.845,P=0.001).CONCLUSION: Oculus Keratograph can objectively measure NIBUT and LTMH,and was more comfortable than traditional tear film examination methods.It can effectively assess tear film function before corneal refractive surgery.

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.

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.
