ABSTRACT
Objective To explore the pathogenic bacterial distribution and drug sensitivity of cholangiitis in children who underwent hepatico-portoenterostomy for congenital biliary atresia in order to provide the guide for appropriate treatment. Methods The clinical data of 300 cases of congenital biliary atresia Kasai postoperative cholangitis in our hospital between 2007 and 2016 were included in the study to analyse the common pathogenic bacteria and antibiotics sensitivity according to its clinical types. Results(1)In the 300 children,cholangitis set on for 541 times,with blood culture positive in 128 cases.(2)The main pathogens of cholangitis after biliary atre-sia included escherichia coli,pseudomonas aeruginosa and enterococcus. Late cholangitis and frequent cholangitis contributed highly to enterococcus infections.(3)The sensitivity rates of escherichia coli and pseudomonas aerugi-nosa to cefoperazone sulbactam were 75% and 78%,respectively,and the rates to piperacillin tazobactam were 82% and 84%,respectively.The sensitivity rates to meropenem were 93% and 76%,respectively.The susceptibility of Enterococcus to vancomycin or linezolid was 100%.Conclusions Cefoperazone sulbactam and piperacillin tazo-bactam can be used as an option of antibiotics for biliary atresia Kasai postoperative cholangitis. In case of poor curative effect,timely replacement of meropenem is suggested.In case of late cholangitis and frequent cholangitis, enterococcus infection can be considered in its diagnosis.
ABSTRACT
Objective To investigate ABCA3 gene polymorphism and its relationship with neonatal respiratory distress syndrome (NRDS) in the Guangxi Zhuang Autonomous Region of China by genotyping and haplotype analysis.Methods Using a tagging single nucleotide polymorphism (tSNP) strategy and TaqMan (r) real-time PCR,we genotyped 4 tSNPs (rs4787273,rs 1 50929,rs 11867129,and rs 17135889) and one additional coding SNP(rs13332514) of the ABCA3 gene in preterm infants with NRDS(NRDS group,n =45) and without NRDS (non-NRDS group,n =45) and subsequently predicted the haplotypes.The minor allele frequency and the haplotype 'distribution were compared between the two groups.Results The minor allele A(0.14 vs.0.05,P =0.046) and genotype AG (0.289 vs.0.111,P =0.035) frequency of SNP rs17135889 in NRDS group were significantly higher than those in non-NRDS group.Totally 6 haplotypes occurred at a frequency ≥0.01,among which,the haplotype TGGAG,depended on rs17135889,was significantly higher in NRDS group than that in non-NRDS group (0.061 vs.0.000,P =0.014).Conclusion The results suggested that SNP rs17135889 of ABCA3 gene might be related to NRDS in preterm population of the Guangxi Zhuang Autonomous Region.Allele A contributes to NRDS susceptibility in preterm infants.
ABSTRACT
Objective To explore the effects of application of probiotics on intestinal flora and related cytokines in infants with cholestatic liver disease.Methods (1) Eighty-four infants with cholestatic liver disease had been hospitalized from October 2010 to June 2011 in the First Hospital of Guangxi Medical University.The infants with cholestatic liver disease were randomly divided into the probiotic intervention group and the non-probiotic intervention group.Quantification of intestinal bacteria was detected by SYBR Green Ⅰ real-time fluorescent quantitative polymerase chain reaction,then the number of 3 kinds of bacteria before and after the treatment was compared.(2) The indices of liver function,blood ammonia,cholesterol were detected.The levels of serum transforming growth factor-β1,tumor necrosis factor-α(TNF-α)and interleukin-6 (IL-6) were measured by enzyme linked immunosorbent assay.Results (1) The number of bifidobacterium,lactobacillus and bifidobacterium/escherichia coli (B/E) were significantly increased (all P ＜ 0.01),whereas the number of escherichia coli was significantly decreased in the probiotic intervention group(P ＜ 0.05),however,there were no differences in the non-probiotic intervention group(all P ＞ 0.05).(2)The indices of total billirubin,direct billirubin,γ-Glutamyltransferase,total bile acid,alanine aminotransferase,blood ammonia,alkaline phosphatase were significantly improved after therapy in 2 groups (all P ＜ 0.05).The levels of TNF-α and IL-6 were significantly decreased in the probiotic intervention group (t--7.31,P =0.00;t =-2.90,P =0.01),but there were no differences in the non-probiotic intervention group.The level of BA was significantly decreased in the probiotic intervention group than the non probiotic intervention group (t =-8.37,P =0.00).(3) The B/E value were significantly inverse correlated with level of serum IL-6 (r =-0.796,P =0.01).Conclusions It may help to restore the intestinal flora and balance the immune function in infants with cholestatic liver disease after application of probiotics.
ABSTRACT
OBJECTIVE： To confirm the efficacy and safety of latanoprost in treating glaucoma.METHODS： In a double blind， randomized control clinical trial， we compared the efficacy and adverse drug reactions of once daily topically applied 0.005％ latanoprost with those of twice daily 0.5％ timolol for 12 weeks in patients with open angle glaucoma or ocular hypertension.RESULTS： The study included 46 patients（22 pts.randomized to latanoprost treatment， 24 pts.to timolol） ， 46 patients remained at the end of the study.Comparing with baseline diurnal intraocular pressure（IOP） ， the IOP reduction（mean±standard deviation） achieved with latanoprost（7.86±2.39） mmHg， （31.1％， P<0.001），and timolol（6.24±2.58）mmHg （24.9%，P<0.001），the difference between the two groups（1.62mmHg） being significant（P<0.01）. Two patients treated with latanoprost had foreign body sensation. No other ocular and systemic adverse reactions related to the two drugs were found. CONCLUSION: The results of this study demonstrated that 0.005% latanoprost applied once daily is well tolerated and more effective in reducing IOP than 0.5% timolol applied twice daily. Thus, latanoprost has the potential for becoming one of the ideal antiglaucoma drugs.
