ObjectiveTo investigate the common pathogenic bacteria and antimicrobial resistance status in neonatal ward to provide guidance for rational clinical medication. MethodsData of 2306 cases in neonatal ward from July 2008 to June 2010 whose body fluid were cultured with positive results of common bacteria were collected. The change of the bacteria and drug resistance was analyzed. Results Among 10 017 body fluid samples, 80 species consisted of 2306 strains of bacteria were found. Enterobacteria accounted for about 53.8% (1241/2306), Klebsiella pneumoniae subsp. pneumoniae (430/1241, 34.6%) and Escherichia coli (341/1241, 27.5%) were the most common ones,and among which 68.1%(293/430)strains of Klebsiella pneumoniaesubsp.pneumoniae and 59.5 % (203/341 ) strains of Escherichia coli were extended-spectrum β-lactamases (ESBLs) producing strains, which were significantly lower than those[78.1% (118/151) and 82.6%(76/92) respectively]during 2003 to 2005 (U=-2.32 and -4.11, P<0.05 respectively).Methicillin-resistant Staphylococcus aureus(MRSA)detectionrate was 8. 5%(23/272)in Staphylococcus, which was lower than that (17.7%, 15/85) in year 2004 to 2006 (U= -2.4, P<0. 05). Methicillin-resistant coagulase-negative Staphulococcus (MRCNS) detection rate was 63.5%(157/247), which was higher than that (32.6%, 97/298) in year 2004 to 2006(U=7.54,P<0.05).The common pathogens of nosocomial infection were Klebsiella pneumoniae subsp.pneumoniae,Escherichia coli , Acinetobacter baumannii and Pseudomonas aeruginosa ; while common pathogens of community infection were Staphylococcus aureus, Klebsiella pneumoniae subsp.pneumoniae and Escherichia coli. Multiple drug-resistant infections in hospital were significantly higher than those in community. Drug susceptibility results showed that the resistance of Staphylococcus haemolyticus,Acinetobacter baumannii and Klebsiella pneumoniae subsp.pneumoniae were especially severe.ConclusionsOpportunistic infections and drug resistant strains increased. The increasing of MRCNS and drug-resistant of Acinetobacter baumanniishouldbepaidmore attention.Comprehensive measures might reduce the production of ESBLs bacteria. The choice of antibiotics should be based on drug susceptibility test.

Objective: To investigate the effect of astragalus on the serum levels of hepatocyte growth factor (HGF), renal function and the damage of renal morphology in ischemic acute renal failure (IARF). To study the protective mechanism of astragalus in IARF. Methods: The rats were pretreated with astragalus or vehicle for 3 days. IARF was induced by left renal artery clipping for 60 min, after the right kidney was removed. Biochemical parameters for serum HGF,blood urea nitrogen(BUN),creatinine(Cr) were measured and histological analyses of the kidneys were performed by tubular grading. Results: There have no significant difference between the serum HGF levels of I/R controls and the levels observed in sham-operated group (P > 0.05). Serum HGF levels in astragalus treated group was significantly increased than those of I/R control group(P < 0.01) .After 4 h of I/R, serum levels of BUN and Cr were increased in I/ R control rats compare with Sham-operated rats(P < 0.01). Astragalus treatment reduced the levels elevation(P < 0.05). Simultaneously,. I/R-induced severe damage in renal morphology were significantly ameliorated by astragalus treatment(P < 0.01). Conclusions: Astragalus pretreatment can alleviate the damage of renal function in IARF. It is may be one of the mechanisms of astragalus for protecting renal tissue in IARF that astragalus can induce the expression of HGF.

AIM: Currently available anti-scarring regimens for glaucoma filtration surgery have potentially blinding complications and safer alternatives would be beneficial. This experiment is to investigate the effect of TGF-β2 antisense oligodeoxynucleotide on differentiation, proliferation of subconjunctival fibroblast following glaucoma filtration surgery.METHODS: Glaucoma filtration surgery were performed on both eyes of 28 rabbits. TGF-β2 antisense oligodeoxynudeotide was subconjunctivally injected in the right eyes (A group), and TGF-β2 missense oligodeoxynucleotide (B group)or PBS(C group) was used at the same method in the left eyes as controls. Rabbits were killed at 4,7,14 and 28 days after surgery. Intraocular pressure (IOP), bleb characteristics were recorded at different time point. Subconjunctival fibroblasts were examined by immunohistochemistry and electron microscopy.RESULTS: The IOP of rabbits in group A was significantly lower at 14 days (6.74± 1.18 mmHg) and 21 days (8.15± 1.97mmHg) after operation than the IOP in group B (8.53± 1.04,9.72± 1.09 mmHg)(P <0.01) and group C(8.79± 1.21, 9.43±1.27 mmHg) (P <0.05). The mean bleb survival time was longer (17.2 days) in group A than that of group B (14.5 days) and group C (13.5 days)(P<0.05). The population of the cells expressing α -smooth muscle actin(α -SMA) and proliferating cell nuclear antigen (PCNA) was significantly reduced in group A compared with the group B and C. The ultrastructure of fibroblast was not altered by TGF-β2 anti-sense oligodeoxynucleotide.CONCLUSION:TGF-β2 antisense oligodeoxynucleotide can prevent the scar formation after glaucoma surgery by inhibit the differentiation and proliferation of subconjunctival fibroblast. It could be a potentially useful anti-scarring alternative for the prevention of late surgical failure.
