Objective To evaluate the role of mierosurgery in surgical treatment to urethrocutaneous fistula after urethroplasty in hypospadias and improve surgical results.Methods From 1999 to 2006,44 urethrocutaneous fistulae (more than 3mm in diameter) after urethroplasty for hypospadias in 33 patients were repaired with different skin flaps.For example,Thiersch technique,urthroplasty,etc.Microsurgical tech- nique was employed in every case.Results The success rates of different procedure were 84.8% (28/33) for Thiersch technique,100% (11/11) for urethroplasty respectively.The total success rate was 88.6%(39/ 44).Conclusion It's just application of skin flap for repairing of big or complex urinary fistula after hypos- padias surgery.The application of microsurgical technique can increase success rate.It is necessary to excise scar and partial urethra for hypospadias fistula combined with urethral structures,cicatricial eontracture and in- curvation of penis.Rich blood-supply,low tension and atraumatic technique are all very important to improve surgery success rates of urinary,fistula after hypospadias repair.

Objective To analyze the causes and outcome of conversion from tacrolimus (FK506) to cyclosporine-A (CsA) in recipients after liver transplantation.Methods 317 consecutive liver transplantation recipients in our department received anti-CD25 monoclonal antibody,FK506, mycophenolate mofetil and corticoid for prophylaxis of cellular rejection.The blood FK506 trough level was (10-15)?g/L within the first 30 days,(8-12)?g/L within next 60 days,and (5-8)?g/L was kept during 90 to 180 days after transplantation.All recipients reveived a follow-up of 6 months. Remits Sixteen out of 317 recipients (5.05%) required conversion from FK506 to CsA.The clinical indications for conversion included:neurological adverse effect of FK506 in 5 cases (31.25%),hema- tological adverse effect in 2 cases (12.5%),gastrointestinal effect in one case (6.25%),not capable of reaching therapeutic window concentration in 3 cases (18.75%),refractory hyperglycemia in 2 ca- ses (12.5%),and economic factor in 3 cases (18.75%).The majority of recipients demonstrated clinical improvement after the switch,except 2 of 16 patients (12.5%) had to be reconverted to FK506 due to renal disadvantage.No dead recipient and adverse effect correlated to immunosuppres- sive agent conversion were seen.Conclusion If necessary,conversion from FK506 to CsA in patients undergoing liver transplantation is safe and effective.

The morphological indexes of the Scuophularia ningpoensis seedlings including the longth, diameter and weight were measured, clustering analysis was used to set up the standard quality grading of seedlings of S. Ningpoensis by SPSS. Field experiment was carried out to measure the indicators of plants growth and development, the yield and the quality. The results showed that the growth and yield of class I seedlings were better than those of class II and III. The content of main active ingredients was affected barely by seedlings classification. To ensure the quality, class II seedlings or above should be used for plantation. The established quality classification standard of S. ningpoensis seedlings was scientific and feasible, and provides the basis for the standardized cultivation of S. ningpoensis.

Objective To find out the distribution characteristics of drinking water with high arsenic in Dali Prefecture, Yunnan. Methods General investigation plus sampling survey was adopted in the city of Dali and 11 counties. The arsenic content in water was tested by half-quantitative fast reagent-box method. The water samples exceeding the standard(≥0.03 mg/L) were re-tested by silver diethyldithiocarbamate eolorimetric method or mercury-atomic fluorescence spectrometric method. Population and children exposed by high-arsenic were statistically analyzed. Results Arsenic content in 15 180 samples from 2639 villages are screened, of which 14 976 samples were less than 0.01 mg/L, reaching 98.66% (14 976/15 180); 110 samples was no less than 0.05 mg/L, only accounting for 0.72%(110/15 180). Water sources with excessive arsenic was found in 29 villages, in a percentage of 1.1% of all covered villages(29/2639). The samples were constituted of 10 399 portions of well water(well was less than 10 m deep), 3903 from spring, 93 from river water, 69 from hot spring water, 26 from reservoir water and 690 from surface water. And for the samples which arsenic content were ≥0.05 mg/L, 89 samples(0.86%, 89/10 399) were from well water, 15 from spring water(0.38%, 15/3903) and 6 from spring water(8.70%, 6/69). A total of 1 561 553 individuals were investigated, in a percentage of 67.83%(1 561 553/2 302 156) of the whole population, among those 420 513 were children, rating 26.93% of the investigated population(420 513/1 561 553); 27 865 were exposed to arsenic, accounting for 1.78% of the investigated population 27 865/1 561 553; 8993 children were exposed, rating 2.14% of the investigated population(8993/420 513). Conclusions There exists high-arsenic water resources in Dali Prefecture, Yunan, so the local inhabitants are in the danger of high-arsenic exposure. Urgent attention shall be paid for the endemic arsenic including investigation, prevention and control.

Panax ginseng is one of the most important traditional Chinese herbal medicine, soil borne diseases influenced the yield and quality severely. In our previous work, endophytic Bacillus subtilis ge25 strain was isolated from ginseng root, and which showed significant antagonistic activity against several most destructive ginseng phytopathogens. In the present work, crude protein and lipopeptid extracts were prepared from LB and Landy supernate by salting out, acid precipitation methods respectively. The antagonistic activity of crude extracts and stability to temperature and protease digestion were examined by ginseng phytopathogen Alternaria panax. Results showed that, the antagonistic activity of crude protein extracts from LB culture was complete and partially lost when treated by high temperature and proteinase K. However, crude lipopeptid from Landy culture showed significant stabile antagonistic activity to them. Acid-hydrolyzation and TLC-bioautography analysis showed, that the crude lipopeptide contained at least one cyclic lipopeptide. In consideration of the stability and perfect antagonistic activity of ge25, further researches will promote the biocontrol of ginseng diseases in the field.
