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] The study was conducted to investigate the effect of micronized fenofibrate on acute insulin response in the subjects with impaired glucose metabolism and hypertriglyceridemia. [Methods] Fifty-three subjects were randomly (2:1 ratio) allocated to fenofibrate group (n=36, including IFG 3 cases, IGT 19 cases, IFG/IGT 6 cases, T2DM 8 cases) or control group (n = 17, including IFG 1 case, IGT 9 cases, IFG/IGT 4 cases, T2DM 3 cases) without any intervention for 3 months. Fasting blood samples were collected for measuring fasting plasma glucose (FPG), free fatty acids (FFA), and lipid profile. IVGTTs were carried out with measurement of plasma insulin before and after treatment. Acute insulin response (AIR), the maximum insulin concentrations (C_(INS,MAX)) to fasting insulin (FINS) ratio (C_(INS,MAX)/FINS) and values of the maximum insulin concentrations increment (△C_(INS)) during IVGTT were calculated as indexes of first-phase insulin secretion. HOMA insulin resistance index (HOMA IR) was used for assessing insulin resistance. [Results] After 3-month treatment, the lipid profile was evidently improved in fenofibrate group. Levels of trigiyceridemia (TG), low-density lipoprotein cholesterol and FFA were significantly reduced and high-density lipoprotein cholesterol increased significantly. Waist circumference was also significantly declined. No change of above indicators was found in control group. In fenofibrate group, C_(INS,MAX)/FINS and △C_(INS) were significantly increased (median 8.4 pmol/L vs. 5.3 pmol/L, 808±473 pmol/L vs. 660±472 pmol/L, both P<0.0001), along with great improvement of AIR (5 585±3 441 pmol·L~(-1)·min~(-1) vs. 4 444±3 642 pmol·L~(-1)·min~(-1), P<0.0001). The level of FINS and HOMA IR was also markedly reduced (108±65 pmol/L vs. 166±115 pmol/L, P = 0.002; 3.8±2.3 vs. 6.0±4.2, P = 0.001). In contrast, there were modest declining in acute insulin response (AIR: 4 313～1 943 pmol·L~(-1)·min~(-1) vs. 5 362±2 861 pmol·L~(-1).min~(-1); C_(INS,MAX)/FINS: median 4.6 vs. 7.0, P= 0.01; △C_(INS): 641±286 pmol/L, vs. 720±321 pmol/L, P= 0.003 9) and increasing HOMA IR (7.8±4.2 vs. 5.6±3.2, P<0.000 1) in control group after 3-month follow-up. The improvement of AIR was correlated with the decreasing of plasma FFA and TG (r=0.41, 0.36, P = 0.002, 0.014), but no correlation with the changing of FPG and HOMA IR. [Conclusions] These results indicated that sbort-term lipid-lowering treatment with fenofibrate evidently improved acute insulin response and alleviated insulin resistance in subjects with impaired glucose metabolism and hypertriglyceridemia. Moreover, the improvement of insulin secretion capacity may be mainly due to the relieving of iipotoxity resulting from finofibrate.

Thirty six patients with hypertriglyceridemia and impaired glucose regulation or newly diagnosed type 2 diabetes, whose fasting plasma glucose was ≤8.0 mmol/L, were treated by fenofibrate for 3 months. Lipid profile, insulin during intravenous glucose tolerance test and oral glucose tolerance test ( including glucose) were measured before and after treatment After treatment, lipid profile was significantly improved. Insulinogenic index (△I30/△G30) and acute insulin response were significantly increased (98. 9vs. 129. 2, 3558.9 vs. 4783. 3 pmol · L - 1 · min - 1, respectively, P ＜ 0. 05 ). Fasting insulin and insulin resistant index in homeostasis model assessment ( HOMA IR) decreased ( 128. 6 vs. 84. 8 pmol/L, 4. 8 vs.3.0, respectively, P ＜0. 05 ). The improvement of insulin secretory function was more significant in patients with higher triglyceride (TG ＞ 3. 3 mmol/L). These results indicate that short-term lipid-lowering treatment with fenofibrate can improve β-cell function and insulin resistance. Patients with higher triglyceride are likely to achieve more benefit from lipid-lowering treatment.

Epidemics of hand, foot and mouth disease (HFMD) have mainly been caused by Coxsackievirus A16 (CVA16) and Enterovirus A 71 (EV-A71), which circulated alternatively or together in the affected area. CVA16 has caused numerous outbreaks and epidemics in multiple countries and geographical regions, and has become an important public health problem. Based on an analysis of the complete VP1 coding region, all CVA16 strains can be divided into genotypes A, B1, and B2. Furthermore, genotype B1 can be divided into subgenotypes B1a, B1b, and B1c. After 2000, no reports of genotype B2 virus strains have been reported. All of the CVA16 strains reported in mainland China have belonged to subgenotypes B1a and B1b. Most CVA16-associated infections cause only mild symptoms; however, some CVA16 infections can lead to severe complications and even death. Vaccination is considered to be the most effective method to control the transmission and infection rate of this virus. A number of research groups are studying various vaccine types, including inactivated vaccines, genetic engineering vaccines, and DNA vaccines, amongst others. In this review, an overview is provided of the research advances in molecular epidemiology and vaccines of CVA16.

AIM: To investigate the preoperative binocular visual function of intermittent exotropia and the rebuilding and recovery of the postoperative binocular visual function, and analyze the effect of binocular visual function on orthophoria after surgery.
METHODS:From January 2011 to January 2014, 47 basic intermittent exotropia patients caming for treatment were collected in the clinical data. The changes in their near stereopsis, binocular visual function, binocular fusion and distance stereopsis after operations were recorded in the form of data. The preoperative binocular vision and the postoperative rebuilding were analyzed and contrasted with each other. In addition, the effect on the postoperative maintaining of orthophoria due to the existence, recovery and rebuilding of binocular visual function were observed.
RESULTS:Intermittent exotropia patients got damage in different levels on their binocular visual functions, especially on distance stereopsis, which was the heaviest and earliest. After the operation, all functions were obviously recovered and reconstructed and the improvements were statistically significant compared against those before the operation (P<0. 01). Patients having binocular visual function or part of it before the operation had a higher ratio of orthophoria compared against the patients who had lost binocular visual function before the operation and the difference was statistically significant (P<0. 01). The recovery and reconstruction of the postoperative binocular visual function played an important role in maintaining the orthophoria.
CONCLUSION: The intermittent exotropia cause damage to the stereopsis which happened the earliest. Obvious recovery and reconstruction of binocular visual function can be observed after the surgery. A relatively good preoperative binocular visual function may lead to the increase in the ratio of orthophoria or cure the intermittent exotropia. Performing an operation when distance stereopsis is damaged can increase the success rate for the surgery and reduce the recurrence rate.

Objective:To study the expressione of autophagy-related protein Beclin-1 and LC3 in cortex and hippocampus of rats after cerebral ischemia reperfusion injury and the efficacy of Edaravone.Methods:Sprague Dawley rats were randomly divided into sham group,model group and Edaravone group.The cerebral ischemia reperfusion model was induced via Zea Longa with blocking the middle cerebral artery of 2 h and reperfusing of 24 h.Animals assigned to sham group were only separated left common carotid artery.Edaravone was injected intraperitoneally at a dose of 1 0 mg/kg at 15 min before reperfusion.The condition of nerve injury of rats was conducted by Neurobehavioral score.The degree of brain injury and success of model were determined based on 2,3,5-triphenyltetrazolium chloride(TTC)staining.The changes of neuron stained by hematoxylin and eosin (HE) in cortex and hippocampus were observed.The expression of Beclin-1 and LC3 was measured by immunohistochemistry.Results:After cerebral ischemia reperfusion the neurobehavioral score of edaravone group was(2.00± 0.67),which was obcviously less than(2.50± 0.53) of model group(P＜0.05).The infraction focus and the neuron injury in cortex and hippocampus neurons were also observed in model group,and the edaravone group reduced above expression.The positive rate of Beclin-1 of each group in cortex were (1 1.08± 0.85)％,(33.42± 1.57)％ and (25.61± 1.39)％,there was significant difference between model group with sham group and edaravone group (P＜0.05).The positive rate of Beclin-1 of each group in hippocampus were (10.34± 0.21)％,(31.82± 1.73)％ and (22.74± 1.26)％,there was significant difference between model group with sham group and edaravone group(P ＜ 0.05).The positive rate of LC3 of each group in cortex were (15.33± 0.47)％,(39.72± 1.73)％ and (28.53± 1.61)％,there was significant difference between model group with sham group and edaravone group(P＜0.05).The positive rate of LC3 of each group in hippocampus were (13.74± 0.37)％,(32.53± 1.43)％ and(25.38± 1.23)％,there was significant difference between model group with sham group and edaravone group (P＜0.05).Conclusion:The expression of Beclin-1 and LC3 was increased after cerebral ischemia reperfusion.Edaravone may reduce autophagy and brain injury through downregulation the expression of Beclin-1 and LC3.

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.

Objective To evaluate the expression of metastasis-associated lung adenocarcinoma transcript 1 (MALAT-1) in ovarian cancer cell lines, and to investigate the biological effects of down-regulated MALAT-1 on OVCAR3 cells.Methods qRT-PCR analysis was used to examine the expression level of MALAT-1 gene in ovarian cancer cells, including ES-2, A2780, SKOV3 and OVCAR3 cell lines.For functional research, four shRNA oligos specially targeting MALAT-1 and a empty vector were designed and constructed into pGPU6/GFP/Neo, then transfected into OVCAR3 cells.qRT-PCR was used to confirm the effective suppression of MALAT-1.Changes of proliferation and adhesion of cells were analyzed by CCK-8 and adhesion assays.Wound-healing, transwell migration and invasion assays were used to examine migration and invasion of MALAT-l-silencing cells in vitro.Results The expression of MALAT-1 gene in OVCAR3 cells was high, and qRT-PCR results confirmed successfully the knockdown of MALAT-1 after transient transfection.After successful suppression of MALAT-1, the proliferation, wound-healing and adhesion ability in vitro were inhibited to some degree.In transwell migration assay, the number of migration cells in MALAT-1-silencing group was 52.17±4.48, which is much less than that in the negative and control groups (286.50± 12.23 and 295.67±6.96, respectively).In invasion assay, the number of invasion cells passing the transwell membrane in MALAT-1-silencing group (37.33±2.40) was also decreased significantly, compared to that in the negative and control groups (239.00±15.72 and 222.67±20.85, P ＜ 0.05).Conclusions shRNA-mediated silence of MALAT-1 can effectively inhibit the proliferation, adhesion, migration and invasion abilities of ovarian cancer cell line OVCAR3 in vitro, indicating MALAT-1 is expected to be a target gene for the treatment of ovarian cancer.
