ObjectiveTo explore the diagnostic methods and surgery pattern at the first time of spontaneous perforation of congenital choledochal cyst.MethodsEleven cases(4 male,7 female) with spontaneous perforation of congenital choledochal cyst were 6 months to 5 years old,and their average course of disease were 4 days.Gustily abdominal distension,abdominal pain,crying and fever were present in all cases.Jaundice(7 cases) and emesis(5 cases) appeared.All cases were detected with physical sign of peritonitis by physical examination.Choledochal cysts were confirmed by CT or B ultrasound in 8 cases.All cases accepted abdominal paracentesis and biliary ascites was drawn.Three different operative procedures were performed:choledochocyst excision & Roux-Y choledocho-jejunostomy(2 cases),choledochotomy with T-tube drainage(3 cases),and cholecystostomy(6 cases).Nine children receiving external drainage operation accepted a second operation to rebuild biliary tract(choledochocyst excision & Roux-Y choledochoje-junostomy) after 3 to 6 months.ResultsAll cases had got satisfactory therapeutic efficacy without any grave complication such as fistula of anastomotic stoma,infection of biliary tract or obstruction of biliary tract.During operation,perforations were located in the juncture of choledochus and cystic duct in 5 children and were not found in the other 6 children.In the second operation,the cases receiving cholecystostomy had less peritoneal adhesion,anatomic structure changes,haemorrhage[(30-50) mL vs(100-200) mL] and operation time[(2.5-3.0) h vs(3.5-5.0) h] than those receiving choledochotomy with T-tube drainage,and did not appear inadequate drainage for cystic duct obstruction.ConclusionsFor children with more organ inflammatory edema and adherence and in a bad overall condition,the first-time operation of cholecystostomy is more reasonable.

Objective To evaluae possible association between interleukin-1 beta (IL-1?) gene exon 5 polymorphism and childhood asthma.Methods The study was conducted in two different groups: asthmatic children(n=55) and healthy children(n=35). The IL-1? gene exon 5 polymorphism was genotyped by polymerase chain reaction-restriction fragment length polymorphism analysis (PCR-RFLP). Results Frequencies of CC,CT and TT genotypes were 92.7%,7.3%,0, and frequencies of C,T allele were 96.4%,3.6% in asthmatic group. However, frequencies of CC,CA and AA genotypes were 85.7%,14.3%,0, and frequencies of C,T allele were 92.9% ,7.1% in healthy group. There were no significant difference in distribution of genotypes and allele frequencies between two groups.Conclusion IL-1? gene exon 5 polymorphism may not be associated with childhood asthma.

Phosphate-dissolving microorganisms are widely distributed in soil, rhizosphere and other ecological environment. Understanding the characteristics of these microorganisms in solubilizing phosphates is helpful to apply them in improving P use efficiency. The obtained results indicated that the fungi had much higher capacity to dissolve the rock than the bacteria. Existence of Fe, Al, Mg and Na in the culture media reduced the rock solubilization by the bacteria, but increased the solubilization of the fungi. The higher content of the rock in the media, the lower capacity of the rock phosphate solubilization was found. The capacity was also significantly reduced if the concentration of C material in the media was higher than 3%. It was also found that the microorganisms destroyed the rock structure. The P was more easily released from the rock at further incubation. In conclusion, there is some potential to utilize the microorganisms to activate the rock phosphate.

AIM:To further elaborate the effect of glucocorticoid receptor(GR) decrease on level of inflammatory media in rats after critical scald.METHOD:The changes of phospholipase A 2(PLA 2) activity and concentrations of tumor necrosis factor alpha (TNF?) and malondialdehyde (MDA), the product of lipid peroxidation metabolism in plasma and tissue homogenate have been studied in scalded rats with or without GR blockade by RU38486.RESULTS:The PLA 2 activity and the concentrations of TNF? and MDA in plasma and homogenate of pulmonary and renal tissue in scalded rats were significantly higher than those in the controls( P

To investigate the biological role of snake venom cystatin(sv-cystatin) in tumor progression, the cDNA of sv-cystatin amplified by PCR from pUC18-cystatin plasmid was cloned into methanol-inducible expression vector pPICZ?A. The linearized recombinant plasmid pPICZ?A-cystatin was transfered into Pichia pastoris, strain GS115 by electrophoration. Transfermants with phenotype Mut+ selected were identified by PCR analysis and induced in 1.0% methanol. The reombinant sv-cystatin protein was examined by SDS-PAGE, Western blot analysis. The molecular mass of expression product was about 14 kDa and approximately 16 mg/L of recombinant sv-cystatin was produced from one of GS115-cystatin transformants. The chromatography purified protein could reduce the activity of papain. The ability of B16F1 cells treated with recombinant sv-cystatin to invade the reconstituted basement membrane decreased significantly (P

The research status is reviewed on taxonomic position, ecology, biological active matter and artificial cultivation of Shiraia bambusicola. Following problems are presented: whether there are new species and host specificity of Shiraia bambusicola. Since the artificial cultivation of stroma of Shiraia bambusicola has not been success, Shiraia bambusicola is in situation of emerge of itself and perish of itself so that it is not beneficial to resource protection and continual utilization of this medicinal fungus. It is pointed out that molecular biology of Shiraia bambusicola should be further researched and technology of artificial cultivation of Shiraia bambusicola should be explored in order to exploit and usage of Shiraia bambusicola.

Objective To investigate the association of angiotensinogen(AGT)gene A-6G、T174M and G-217A polymorphisms with the risk of essential hypertension(EH)in the elderly of Han nationality.Methods Genotypes of AGT gene A-6G,T174M and G-217A polymorphisms in 177 aged EH patients and 86 sex and age-matched controls were analyzed with gene chip technology.Results The A-6G and T174M polymorphisms of AGT gene were significantly associated with EH.The numbers of the three genotypes of A-6G were 113,58 and 6 in the patient group and 70,15 and 1 in the control group(P= 0.014)and those of T174M were 94,77 and 6,60,25 and 1(P=0.031),respectively.G-217A polymorphism was not related to EH.Individuals carrying A-6G AA and T174M CC genotypes showed 57% and 56% lower risk of EH(OR=0.43;95%CI=0.23-0.82 and OR=0.44;95%CI=0.25-0.79, respectively).Conclusions The A-6G AA and the T174M CC genotype may be related with decreased risk of EH and G-217A polymorphism may have little role in the etiology of EH in Han nationality.
