Antimicrobial susceptibility testing (AST) is an important means to clinical microbiology. At present, there are no standard AST methods for aquatic pathogens comparing with human and veterinary pathogens. We reviewed the recent research progress on establishing these methods and discussed the key factors in AST of aquatic pathogens. Furthermore the defect of AST of aquatic pathogens in China was profiled and prospect for further research was put forward.

Objective:To evaluate the utilization of both parenteral nutrition and enteral nutrition drugs for the reference of clinical medication.Method:The statistics on nutrition drugs in a hospital from 2006 to 2008 were conducted by the defined daily dose method.Result:The cost ratio of the nutrition drugs to the total drug consumption increased annually.Glutamine was the leading nutrition drug according to the increase tendency of DDDs.The utilization ratio of enteral nutrition drugs to the whole nutrition drugs increased continuously,from 8.72%to 15.58%during 2006 to 2008.Conclusion:Nutritional support has attracted more and more clinical attention,and DDDs of the enteral nutrition increases rapidly.

AIM: To explore the effect of hypertonic sugar eyes drops with local to the oxygen therapy for severe corneal edema after cataract surgery.METHODS: Totally 68 patients (68 eyes) with severe corneal edema after phacoemulsification were selected from January 2014 to December 2015 in our hospital, who were aged 53-80(64.45±4.24), including 30 males and 38 females.According to different treatment, they were divided into treatment group (34 cases) given conventional therapy + hypertonic sugar eyes drops with local to the oxygen therapy, the control group (34 cases) given conventional treatment + hypertonic sugar eyes drops.Visual acuity and corneal situation were observed during the treatment.RESULTS: Corneal edema fade time of treatment group was 11.62+0.53d, that of control group was 15.23±0.62d, the difference between the two groups was significant (P<0.05).Preoperative best corrected visual acuity (BCVA) and corneal endothelial cell count had no significantly difference between the two groups while the corneal endothelial cell count were significantly different compared with postoperative of the two groups (P<0.05).At 7d after treatment, the BCVA and corneal endothelial cell count had significantly difference between the two groups (P<0.05), which did not have significant difference at 1mo after treatment (P>0.05).The effective rates of the two groups was significantly different (P<0.05).CONCLUSION: Hypertonic sugar eyes drops with local to the oxygen therapy is effective for severe corneal edema after cataract surgery.

Objective To compare the relative efficacy and quality of extraction of human fecal DNA using four methods.Methods Real-time PCR were utilized for analysis both quantification and quality of the fecal targeted bacteria(including gut all eubaeterium,Bacteriodes-PrevoteUa group,Bifidobacterium spp Enterobacteriaceae and Enterococcus spp)by using 16s rRNA gene-targeted genus or group-specific primer sets.Results The negative rat of PCR product from method 3(phenol-chloroform plus bead-beating) was about 40%(4/10)by using universal primers,the PCR inhibition disappeared after fecal DNA purified with column.The total fecal 16s rRNA gene copy numbers(per gram of wet weight of feces)as well as the numbers of Bacteriodes-Prevotella group from method 1(QIAamp~DNA stool mini kit)and 4(QIAamp~ DNA stool mini kit combined with bead-beating)was higher significantly than that from method 2(FastDNA ~Kit,Biol01)and 3(P

Objective To evaluate the clinical outcome and relative factors of intervention treatment for atherosclerotic renal artery stenosis in elderly patients.Methods The clinical data of 79 patients diagnosed as atherosclerotic renal artery stenosis by angiography and treated by revascularization were analyzed.Results There were 55(69.6%)successes and 24(30.4%)failures in decreasing blood pressure and 28(35.4%)successes and 51(64.6%)failures in improving renal function after intervention treatment.Predictors of favorable outcome of intervention treatment in decreasing blood pressure were related to lower urine protein,higher glomerular filtration rate,higher systolic and diastolic blood pressure before treatment,lower resistance index(RI)of renal artery,and no complication of cerebral vascular diseases.Predictors of favorable outcome of intervention treatment in improving renal function were related with percentage of angiographic stenosis,category of antihypertension and lower urine protein.The logistic regression analysis showed that the percentage of angiographic stenosis was the most important predictor of intervention treatment for blood pressure control,age and level of serum creatinine before intervention treatment were the most important predictors of intervention treatment for improving renal faction.Conclusion Percentage of stenosis(≥85%),age(133 ?mol/L)can be used as the predictors of therapeutic success for renovascular stenosis in older patients.

Objective:To analyze the use status of antibiotics and the resistance of clinic isolate bacteria against the commonly used antibiotics before and after the intervention. Methods:Using the information retrieval systems, the consumption of antibiotics in the inpatients during the 1st quarter of 2012(before the intervention) and the same period of 2013(after the intervention) was com-pared. According to the defined daily dose ( DDDs) , the antibiotics were ranked, and the resistance rate against the commonly used antibiotics was analyzed. Results:Compared with the top ten before the intervention, the top ten after the intervention was changed sig-nificantly, however, cephalosporins was still the main species. After the intervention, the overall decline in DDDs was significant, the separation rate and distribution of bacteria remained stable. ESBLs enzyme production rate of Enterobacteriaceae Escherichia coli was re-duced by 7. 61%, and that of Klebsiella pneumoniae was reduced by 1. 34%, and the resistance rate against the commonly used antibi-otics was in an overall downward trend. The resistance rate of Gram-positive staphylococci against the commonly used antibiotics was de-creased, while that of Gram-positive enterococci showed notable difference. Conclusion:The DDDs of antibiotics and bacterial resist-ance rate are in an overall downward trend in our hospital after the intervention;however, there is still exception. Therefore, the clini-cal antimicrobial susceptibility tests should be performed as soon as possible to help the choice of antibiotics.

Mean platelet volume (MPV) is an early marker of platelet activation.Larger platelets,compared to small ones,increase platelet adhesion and aggregation,and present a higher thrombotic activity.Some studies have explored the association between MPV and the morbidity of portal vein thrombosis (PVT).The aim of this study was to evaluate the predictive effect of MPV in patients with PVT by a meta-analysis.We searched Pubmed,Web of Science,SCOPUS,OVID,CNKI and CBMD from database inception to September 13,2017.Seven studies in accordance with selection criteria were included.The extraction of basic data was independently conducted by two reviewers.The mean difference in MPV between PVT patients and controls were pooled with weighted mean difference (WMD)and 95％ confidence interval of 0.88 fl (95％ CI:0.61-1.15).A random-effect model was chosen for an obvious heterogeneity in the pooling (Chi-square=27.12,df=6,P＜0.0001,I2=77.9％).The sources of heterogeneity were from the difference of primary disease of participants and portal vein diameter.Taken together,our results reveal that MPV is a predictive indicator in patients with PVT.

Objective To evaluate the olfactory functions in patients with Parkinson's disease (PD) with a smell identification test developed for the Chinese population and to examine possible factors contributing to PD patients' olfactory performance.Methods Fifty-five patients with idiopathic and nondementia PD and 55 demographically matched healthy controls (HC) were recruited and their olfactory identification tested using the Chinese Smell Identification Test developed by the Institute of Psychology at Chinese Academy of Sciences.Results Olfactory identification score was significantly lower (t =-6.827,P＜0.01) in the PD group (19.3 ±5.4) as compared with the HC group (26.5 ±5.7).Of all PD patients,63.6％ scored over 1 SD below the age norm.In particular,of those with Hoehn-Yahr ratings between 2 to 3,77.8％ scored over 1 SD below the age norm.Receiver operating characteristic (ROC) curve analysis indicated that a cut-off score of 22.5 on the Chinese Smell Identification Test distinguished between PD patients and HC with a sensitivity of 74.6％ and specificity of 70.9％.Within the PD group,age,education,Hoehn-Yahr rating and Mini-Mental State Examination score were not found to correlate with olfactory performance (all P ＞ 0.05).Conclusion PD patients in China show significant impairment of olfactory identification,which is effectively captured by the Chinese Smell Identification Test.
