SO2 is one of the main pollutants in the air. Tradational disposal methods are limited in the industrial application owing to their high cost. Some foreign scholars began to research in microbial treatment of SO2 both in laboratory test and in full-scale test in recent years and good results were achieved. This method can significantly lowering costs and acquire sulfur product and microbial biomass protein of high quality. The microbial method which is simple, effect and of low costs can satisfy needs of industry and give attention to environmental, economical and social benefits, therefore, it will have amplitude and well application prospects.

Objective To observe the treatment and outcomes of gastric stump cancer(GSC) after subtotal gastrectomy,and to analyse the possible related factors for the development of GSC. Methods The clinical data of 693 patients with subtotal gastrectomy were retrospectively analysed.The development,treatment and outcomes of GSC were observed,and the possible factors associated with the development of GSC were analysed. Results Seventy-six cases of GSC emerged in the 693 patients with subtotal gastrectomy.Fifty-one of the 76 cases were perfomed radical operations(n=36) or palliative resection(n=15).No death was found during the perioperative period,and the median survival time was 32.7 and 14.2 months,respectively.Those 25 without surgical management died 3 to 11 months after the development of GSC.Among the 76 cases with GSC,stomach was found as the original site of ulcer in 59(22.3%,59/259),and duodenal bulb in the other 17(3.9%,17/434)(P

Microbial production of 5-aminolevulinic acid (5-ALA) by photosynthetic bacteria compared to other bacteria and algae was reviewed. During anaerobic cultivation of the Rhodobacter spaeroides mutant strain, control of the redox potential was effective or producing large amounts of extracellular ALA. ALA has been practically applied in agriculture as herbicide, pesticide and growth-promoting factor for plants. New agriculture applications including salt tolerance and cold temperature tolerance of plants were also desired. Finally recent medical application for cancer treatment, tumor diagnosis and other clinical uses were discussed.

Objective To assess the value of serum N terminal pro-brain natriuretic peptide(NT-Pro-BNP) in the diagnosis of congestive heart failure(CHF) and evaluation of cardiac function in children with ventricular septal defect (VSD).Methods Fifty one children were enrolled from March 2004 to March 2005.NT-Pro-BNP was measured by enzyme immunoassay technique.At the same time,left ventricular ejection fraction(LVEF) and left ventricular shortening fraction(LVFS) were detected with echocardiography.Results The data of NT-Pro-BNP were showed but the logarithms of which were normal distribution.The values of NT-Pro-BNP were developed successively along with the severity of cardiac function.But there was no difference between the group of no heart failure and mild heart failure.But the values of LVEF and LVFS had no differences in the control,the mild and the moderate heart failure and the same time all of which beyond the standard of diagnosing heart failure.NT-Pro-BNP could reflect the degree of heart failure or cardiac function (r=0.826).But LVEF and LVFS can not reflect the degree of the cardiac function.Conclusions NT-Pro-BNP can reflect the degree of the cardiac function in VSD,and the degree of the heart failure can be classed by the levels of serum NT-Pro-BNP.But the value of LVEF and LVFS can not reflect the degree of the heart failure in the same disease.

OBJECTIVETo explore therapeutic effects of Modified pinning combined with external tension band for the treatment of Gartland type III humeral supracondylar fractures in children.

METHODSFrom February 2009 to November 2010, 79 children with Gartland type III humeral supracondylar fractures were treated by modified pinning (pinning cross internal and external condyle assisted with lateral condyle) combined with external tension band (crossing needle end and hooking around) through lateral approach of elbow. There were 47 males and 32 females, with an average age of 8.7 years (ranging from 2.5 to 14 years). The time from injury to operation was 2 h to 8 d. The elbow joint function and Carrying angle were observed before and after treatment. The Flynn criteria were used to evaluate therapeutic effects.

RESULTSSixty-one patients were followed up (18 patients' data were lost) for 6-30 months (mean 13.5 months). According to Flynn criteria, 53 patients got excellent result, 7 good and 1 fair.

CONCLUSIONTreatment of child Gartland type III humeral supracondylar fractures with modified pinning combined with external tension band through lateral approach of elbow is believed to be an ideal method, which has advantages of reliable fixation, rapid recovery and less complications.

Objective To evaluate the multi-slice spiral CT scan of liver dynamic dual-phase three-dimensional vascular imaging portal phase clinical value. Methods 80 cases in clinic, who were patients with liver function and imaging diagno- sis of liver and portal hypertension in liver cirrhosis, and 20 cases of healthy persons were carried out multi-slice spiral CT dual-phase scanning. The workstation used volume rendering techniques (VR) and maximum density multi-planar recon- struction technique for reconstruction. Results The hepatic arterial phase VR image and MIP MPR images can clearly show the celiac trunk, splenic artery, hepatic artery or artery and its branches, including 2-3 grade tumor blood supply variation of blood vessels and blood vessels, the portal venous phase, VR images and MIP MPR images clearly show the 1-6 level structure and the portal vein and hepatic vein branches of 1-3, with strong three-dimensional sense of space. Conclusion The multi-slice spiral CT three-dimensional reconstruction of portal vein imaging is a fast and effective non-invasive an- giography techniques, contributing to the clinical choice of reasonable efficacy of treatment programs and follow-up.

[Summary] Diabetic nephropathy is one of the major chronic microvascular complications of diabetes ,which is the leading cause of end‐stage renal disease ,as well as the main cause of death in diabetic patients. Glomerular endothelial cell is an important component of the glomerular filtration barrier ,which is directly related to the materials of circulation ,and it can be easily damaged by glucose ,lipid and inflammatory factors. Under the hyperglycemia ,the PKC pathway ,the polyol pathway and oxidative stress were activated ,producing an excess of advanced glycation end products and reactive oxygen species ,which damage the endothelial nitric oxide synthase ,reduce the generation of nitric oxide ,while produce a large number of Ang Ⅱ. Ang Ⅱ damage the endothelial cell. In addition ,there are crosstalk between glomerular endothelial cells and endothelial cells ,which also cause endothelial cell injury. Here ,we reviewed the role of endothelial cell injury in the pathogenesis of diabetic nephropathy.

AlM:To evaluate the efficacy of retrobulbar injection of triamcinolone acetonide ( TA ) combined with 577nm laser macular grid photocoagulation for the treatment of cystoid macular edema.
METHODS: Fifty-eight cases ( 66 eyes ) with cystoid macular edema caused by different diseases were recruited in this study. The included patients were treated with both retrobulbar injection of triamcinolone acetonide and 577nm laser macular grid photocoagulation. The best corrected visual acuity, macular thickness, fundus and intraocular pressure were observed in the 1wk, 1 and 3mo after the treatment in all of the included cases.
RESULTS: After treatment, all of the 66 eyes showed cystoid macular edema partially or completely subsided according to optical coherence tomography and fluorescence fundus angiography; 54 eyes ( 82%) visual acuity improved, 12 vision remained the same.
CONCLUSlON: Retrobulbar injection of triamcinolone acetonide combined with 577nm laser macular grid photocoagulation has good curative effect, simple operation procedure and rare complications in the management of cystoid macular edema.
