0.05). Regarding to the grade of irradiation mucositis, the majority of patients in the treatment group were at stage Ⅰ-Ⅱ,while those in the control at stage Ⅲ-Ⅳ(P0.05).No adverse drug reaction was observed in both groups during irradiation process.Conclusion:Actovegin can postpone the development of irradiation oropharyngeal mucositis and decrease the incidence of gradeⅢ and Ⅳmucositis.

OBJECTIVE To investigate the influence of intermittent catheterization methods and indwelling catheterization methods on the urinary tract infection in patients with spinal cord injury.METHODS After eighty cases of spinal cord injury,the urine retention patients caused by bladder dysfunction were respectively used intermittent catheterization and indwelling catheterization.The urinary tract infection rates of regucally urine culture were compared.By use of intermittent catheterization,the bladder function was trained.Bacteria culture and identification of the urine from the patients were conducted after 15 or 30 days of intermittent catheterization and indwelling catheterization respectively.RESULTS The rates of urinary tract infection(colony count≥1?10 CFU/ml) after 15 or 30 days of intermittent catheterization were 32.6% and 31.5%,respectively.Which were significantly lower than those of indwelling catheterization(100%)(P

Objective To investigate the importance of plasmid-mediated quinolone resistance in the development of quinolone resistance in clinical isolates of gram-negative bacteria.Methods A total of 541 consecutive clinical isolates of gram-negative ba- cilli resistant or intermediate to ciprofloxacin were screened for the qnrA gene by PCR.Conjugation experiments were carried out with azide-resistant E.coli J53 as a recipient.The aac(6')-Ib-cr gene was detected.The mutations in the quinolone-resist- ance-determining region (QRDR) of the gyrA and parC genes were identified in qnrA positive strains.Results qnrA was identi- fied in 7 of the 541 strains.Among the qnrA positive strains,5 were Enterobacter cloacae.No qnrA was detected in nonfer- menters.Quinolone resistance was transferred in 4 of 7 qnrA positive strains.Transconjugants had 12-to 125-fold increases in MIC of ciprofloxacin relative to that of the recipient.Seven strains contained qnrA with a nucleotide sequence identical to that originally reported.Two transconjugants with higher ciprofloxacin MICs contained aac(6')-Ib-cr gene.Mutations occurred in the QRDR of the gyrA and parC genes in 5 PCR-positive clinical strains.Conclusions Transferable plasmid-mediated quinolone resistance associated with qnrA is highly prevalent in clinical strains of Enterobacter spp.aac(6')-Ib-cr gene and mutations in the quinolone targets may co-exist with qnrA,which may contribute to the further increase of resistance to quinolones.

Total 149 strains of endophytic bacteria were isolated from different healthy organisms of Glycyrrhiza inflata Bat. from Xinjiang. The fermented liquids of these strains were screened by TLC and analysed by HPLC, and the glycyrrhizinic acid monoammonium salt was taken as standard control at the same time. Only one endophtytic bacterial stain of Bacillus subtilis could produce Glycyrrhizinic acid monoammonium salt analogue.

Objective To improve the awareness of the CT and/or MRI appearances and clinical presentations of Kasabach-Merritt syndrome(KMS),6 cases were reported.Methods The CT and/or MRI and clinical characters of 6 cases of KMS were reviewed and analyzed.Results Thrombocytopenia,and consumption coagulopathy were presented in all 6 cases.The paravertebral mass of posterior mediastinum, right pericardial lesion,skin and soft tissue of left arm were shown as iso-,hypointensity on T1-weighted image,iso-,hyper-intensity on T_2-weighted image,and with heterogeneous enhancement after contrast administration in three cases.Splenomegaly was presented in one case,it showed homogenous hypoattenuation on unenhanced CT,and diffused heterogeneous enhancement after contrast administration. On MRI,spleen was shown as hypointensity on T_1-weighted image,hyperintensity on T_2-weighted image, and with heterogeneous enhancement after contrast administration.There were lesions in both bones and spleen in one case.Osteopenia and thinned cortex were shown on the metaphyses of upper and lower extremities.Spleen enlarged and showed multifocal hypoattenuation lesions,the peripheral region enhanced on the early phase,and some of the lesions filled on the delayed phase after the contrast administration.One case showed huge hypoattenuation lesion in the left lobe of liver with gradually filling of the mass after peripheral enhancement.Conclusion Thrombocytopenia and consumption coagulopathy suggest the entity of extensive hemangioma.Splenomegaly with diffuse or focal hypoattenation or hypointensity in MRI infers the diagnosis of hemangioma.

Objective To investigate the roles and significances of MMP-2 and MMP-9 in diffuse proliferative lupus nephritis by repeated renal biopsy.Methods Seventeen patients diagnosed by renal biopsy as WHO typeⅣlupus nephritis were analyzed by immunohistochemistry staining for MMP-2 and MMP-9. Double staining for MMP-2 and MT1-MMP,MMP-9 and CD68 were also performed.Patients had repeated renal biopsy after followed up for 2.5 years.The relationship between expressions of gelatinases and pathological activity index and clinical data were studied.Results MMP-2 immunoreactivity was detected in normal controls and was increased in diffuse proliferative lupus nephritis.MMP-9 staining,which was almost negative in normal giomeruli,was increased much more significantly in diffuse proliferative lupus nephritis. The immunoreactivity of MMP-2 and MMP-9 was positive in MT1-MMP staining and CD68-positive macrophages, respectively.The expression of MMP-2 and MMP-9 was reduced by 70% and 62% in 10 patients whose clinical condition was partially alleviated,while the expressions in 7 patients whose clinical condition was not alleviated,were only reduced by 27% and 32%.The staining for MMP-2 and MMP-9 were correlated with activity index of lupus nephritis and proteinuria.Conclusion Up-regulation of gelatinases expression in diffuse proliferate lupus nephritis is correlated to activity index of the disease.

?AIM: To study the association of the single nucleotide polymorphism ( SNP) rs1157699 in the calcitonin receptor-like receptor ( CRLR ) gene with primary angle closure ( PAC) in a Han Chinese population.?METHODS: All samples, involved 232 PAC cases and 306 controls, were obtained from an epidemiologic survey conducted in Funing, Jiangsu Province, China. Genotyping were carried out by TaqMan-MGB probe using the real time quantitative polymerase chain reaction system to study the relationship between SNP of rs1157699 in CRLR gene and PAC.?RESULTS: The prevalence of CRLRrs1157699 genotype was 67.4%, 30.0%, 2.6% for CC, CT, TT in cases, and 71.3%, 27.0%, 1.7% in controls respectively.There was no difference between the two groups in the distribution of genotype and allele frequencies of rs1157699 (P>0.05).?CONCLUSION:Our results do not support a significant role for rs1157699 in CRLR with PAC.
