ABSTRACT
Objective To understand the drug resistance situation of pathogenic bacteria clinically isolated in Dongguan Munici-pal People′s Hospital during 2013.Methods The drug sensitivity test were performed by adopting the associated reagent strip of the VITEK2-compact microbial analyzer from French bioMerieux company,including AST-GN test,AST-GP33 test,AST-GP68 test and K-B method (only for Haemophilus influenzae).The data were analyzed by the Whonet5.5 software.Results In 2013,to-tally 7 543 strains of pathogens were detected out,including 6 031 strains(79.9%)of Gram negative bacteria,1512 strains(20.1%) of Gram positive bacteria.The detection rates of ESBL in Escherichia coli and Klebsiella pneumoniae were 46.9% and 28.1%,re-spectively.The detection rates of MRSA and MRCNS in Staphylococcus were 16.8% and 77% respectively.The detection rate of multidrug resistant strains was 21.5%.The resistant rate of Escherichia coli and Klebsiella pneumoniae to ampicillin and cefazolin were greater than 60%;which of Pseudomonas aeruginosa to ampicillin,furosemide,trimethoprim-sulfamethoxazole,ceftriaxone,ce-fotetan and cefazolin was more than 80%;which of Baumanii to imipenem was still 61.2%,which to aztreonam,ceftriaxone,cefotet-an,cefazolin was more than 98%.The resistance rate of Enterococcus faecium to vancomycin was 6.2%.No vancomycin-resistant Staphylococcus aureus strain was detected out.Conclusion The detected pathogenic bacteria in 2013 were dominated by Gram-neg-ative bacilli,the multidrug resistant bacterial strains had the higher detection rate,the drug resistance of Baumanii was serious.The resistance of Enterococcus faecium to vancomycin showed the increasing trend.Monitoring the bacterial drug resistance every year and understanding the change of pathogenic drug resistance can provide the basis for the rational selection of antimicrobial drugs in clinic.
ABSTRACT
Objective To understand the serotype distribution ,prevalence and antimicrobial susceptibility of Salmonella strains isolatd from diarrhea patients in Dongguan ,Guangdong Province .These data may be useful for disease control and prevention and clinical treatment .Methods From April to December in 2013 ,we collected 1 150 stool specimens from diarrhea patients . Salmonella strains were cultured by using Salmonella selenite brilliant green sulfa enrichment broth and selective chromogenic plates .Antimicrobial susceptibility was tested by ATB microbial identification and drug susceptibility system .Results A total of 72 strains of Salmonella were identified including 21 serotypes .The detection rate was 6 .3% (72/1 150) .Most of the strains were Salmonellatyphimurium (22/72 ,30 .5% )and Salmonellaenteritis (16/72 ,22 .2% ).Forty‐two (58 .3% )of the strains were isolated from the patients under one year of age ,12 (16 .7% ) strains from the patients of 3‐10 years of age ,and 18 (25 .0% ) strains from the patients of at least 20 years old .The results of antimicrobial susceptibility testing showed that 50 .0% of the strains were resistant to piperacillin and 48 .6% resistant to ticarcillin .Conclusions The prevalence of Salmonella typhimurium is the highest in local Salmonella‐associated diarrhea patients ,followed by Salmonella enteritis .Most of the Salmonella diarrhea occurred in the patients under one year of age .Clinicians should strengthen the monitoring of Salmonella in patients with diarrhea , especially in infants and young children , for early detection and treatment so as to reduce complications .
ABSTRACT
Objective:To observe the clinical effect of ulinastatin combined with somatostatin in the treatment of acute severe pan-creatitis. Methods:Totally 130 cases of severe acute pancreatitis patients were randomly divided into two groups with 65 cases in each. The control group was given the routine treatment and 3mg somatostatin in 250ml sodium chloride injections, ivd, bid, and the treatment group was given 10ku ulinastatin in 250ml sodium chloride injections additionally, ivd, bid. After the 10-day treatment, the clinical symptom disappearance time, the recovery time of respiratory and heart rate, length of stay, blood and urine amylase, and clin-ical total effective rate were compared between the two groups. Results:The symptom disappearance time, recovery time of respiratory and heart rate and length of stay in the treatment group were all shorter than those in the control group (P0. 05). The total effective rate of the treatment group was 95. 38%, while that of the control group was 73. 84% with significant difference (P<0. 05). Conclusion:The application of ulinastatin in the treatment of severe acute pancreatitis shows obviously curative effect, which can effectively improve the clinical symptoms and shorten the course of disease, and is valuable in clinical use.
ABSTRACT
Objective To observe the effects of hyperbaric oxygen (HBO) on the expression of FasL mRNA and caspase-3 protein in renal tissue after renal ischemia-reperfusion injury (IRI) in order to elucidate the underlying mechanisms.Methods Rats were randomly divided into thrcc groups: sham group(n=8),IRI group(n=8) and IRI+HBO group(n=8).The IRI group and the IRI+HBO group recieved 45 minutes hibateral renal ischima and the IRI +HBO group received additional HBO therapy at the 1st,24th and 48th hour after ischemia.The kidneys were removed at the end of HBO therapy.Malondialdehyde (MDA) level and superoxide dismutase (SOD) activity were measured to determine the extent of oxidative stress.The expression of FasL mRNA and caspase-3 protein was detected by quantitative real-time PCR and immunohistochemical staining in renal tissue respectively.Results Compared with the sham group,MDA level increased markedly and SOD activity decreased markedly after ischemia.After HBO treatment,MDA level decreased and SOD activity increased significantly (P ＜0.05).In IRI group,the expression of FasL mRNA and caspase-3 protein were higher than those in the sham group (P＜0.01),which were reduced significantly by HBO treatment (P＜0.01).Conclusion The expression of FasL mRNA and caspase-3 protein increases along with the lasting of reperfusion and HBO exhibites protection against cell apoptosis through improving the antioxidant-oxidant balance and reducing IRI in acute stage of IRI.
ABSTRACT
Objective To investigate the curative effects of dexamethasone in the prevention of delayed encephalopathy after acute carbon monoxide poisoning in the rats.Methods Eighty healthy male Wistar rats were randomly(random number)divided into hyperbaric group(H),dexamethasone group (D),combined treatment group(C)and model control group(M)after carbon monoxide poisoning,twenty rats in each group.Twelve air-modeling rats were selected as normal control group(N).Using eight-arm maze training and testing,the rat's function of cognitive and memory was detected.The serum MBP levels were detected by enzyme-linked immunosorbent assays(ELISA).Magnetic resonance imaging was used for observing the demyelination of the head and the morbidity of delayed encephalopathy.Measured data was analyzed with single factor analysis of variance(one-way ANOVA).Results The result of eight-arm maze showed that there were 6,7,1,1 rats with delayed encephalopathy in groups M,H,C,D,respectively.At 3 days after poisoning,except N group,the serum MBP levels of every groups increased significantly.At 10 days after poisoning,serum MBP levels in groups C and D were significantly decreased,then returned to normal levels at day 18.The serum MBP in groups M and H was higher than normal levels at all the time.Head MRI showed except D group,the rest groups were abnormal signals,which appeared 7 in M group,6in H group and 1 in C group.Conclusions Dexamethasone administrated as soon as possibly after acute carbon monoxide poisoning may reduce the serum MBP levels,prevent demyelination occurs,decrease the pathological damage,eventually play a preventive role in DE.
