OBJECTIVETo explore whether fractional anisotropy (FA) value could be taken as a quantitative indicator for tracing and reexamining amyotrophic lateral sclerosis (ALS), and to analyze the correlation between FA value and integrative medical treatment.
METHODSTotally 18 ALS patients were recruited in this study. All patients received diffusion tensor imaging (DTI) using 3. OT (Propeller HD) MRI twice. Six regions of interest (ROI) were selected to measure FA values. Survival analyses were performed in 11 cases of end point events.
RESULTS(1) Three ROI (cerebral peduncle, posterior limb of internal capsule, and corona radiata) all indicated that FA value was the highest in patients with mild health status scale of amyotrophic lateral sclerosis (ALS/HSS). (2) There was statistical difference in the means of FA values in cerebral peduncle, posterior limb of internal capsule, and corona radiata of 18 cases between initial examination and reexamination (P < 0.01). (3) Kaplan-Meier survival curve showed the survival rate of ALS patients decreased as time went by, with the median survival time of 48 months.
CONCLUSIONSFA value was inversely proportional to the severity of ALS, the more severe, the lower FA values. FA value was an objective indicator for assessing the severity of ALS. ALS is an incurable disease till now. Integrative medical treatment might become one direction for ALS patients.

We investigated the contamination,antimicrobial resistance and the virulence genes carriage of Salmonella spp. in duck slaughter chain.Suspected strains were isolated from slaughterhouse samples according to GB 4789.4-2010 and identi-fied by duplex PCR,and then the positive strains were used for serotype analysis.Subsequently,positive strains were tested against 10 different antimicrobial agents using Kirby-Bauer disk diffusion method,the results were determined on the basis of CLSI standard.Finally,9 virulence genes were detected among positive strains by PCR.The results showed that 9 9 Salmonella isolates were recovered from 343 samples and total isolation rate was 28.86%.The prevalence of Salmonella before slaughte-ring,at depilation stage,at evisceration stage,in duck meat and after slaughtering was 45.71%,22.68%,24.72%, 38.33% and 25.81%,respectively.Seven serotypes were de-tected and most of them were S.Indiana,S.Newlands,S. Anatum.The Salmonella isolates were most frequently re-sistant to nalidixic acid(91.92%),the resistance rates of tet-racycline (43.43%),ampicillin (42.42%),trimethoprim-sulfamethoxazole (34.34%),ciprofloxacin (29.29%),ceftri-axone (27.27%),gentamycin (24.24%),and kanamycin (22.22%)were at a medium level.The resistance rates of amoxicillin-clavulanic acid (9.09%)and minocycline (6.06%)were relatively low.The multi-drug resistance rate of Salmonella isolates,which was 47.47%,showed a high especially in S.Indi-ana,S.Typhi and S.Typhimurium.It was notable that the harboring rates of virulence gene spvR(94.95%),avrA (93.94%),ssaQ(90.91%),mgtC(87.88%),sopB(83.84%),bcfC(80.81%),siiD(77.78%)among Salmonella isolates were at high level,in contrast to the lower carriage rates of spvB(29.29%),spvC (11.11%).In summary,the results indica-ted that the duck slaughter chain was easily contaminated by Salmonella spp.with different serotypes,different antibiotic re-sistant patterns and high virulence genes harboring rate.Relevant slaughterhouse and departments should strengthen supervi-sion in sanitation and manage the use of antimicrobial agents,to guarantee food safety and public health.

OBJECTIVE: To observe the impact of energy saving light,incandescent light and circadian light on the ethology of depressive rats and explore its possible mechanism on affecting the secretion of melatonin. METHODS: Thirty rats aged 6weeks were randomly selected from 40 specific pathogen free health female SD rats after they adapted to the living environment,depressive rat models were established in the rats by bilateral ovariectomy combined with isolated living and chronic unpredictable mild stress stimulation at the age of 11-14 weeks. Then these 30 ovariectomized rats were randomly divided into 3 intervention groups,including an energy saving light group,an incandescent light group and a circadian light group,with 10 rats in each group. The rats in these 3 groups were given specific experimental light intervention for 3 weeks respectively at the age of 17 weeks. The other 10 rats were raised in conventional environment as the control group. Their body weights were measured at the age of 17,19,20 and 21 weeks. The ethology tests were carried out by sucrose preference test and the open-field test at the age of 7,14 and 20 weeks respectively. The melatonin levels in peripheral blood of 7 time points from 19: 30 to 8: 30 were measured in the rats at age of 21 weeks. One rat in each group at every time point was randomly selected for examination. RESULTS: At the age of 17 weeks before light-intervention,the body weights of rats in 4 groups showed no significant difference( P > 0. 05). After light-intervention,at the age of 17-20 weeks,the body weights of rats in 3 intervention groups were gradually increased with the increase of age( P < 0. 05).There was no significant difference between body weights of rats at the age of 21 weeks and those at the age of 20 weeks in each group( P > 0. 05). At age of 7 weeks,no significant differences were found in sucrose consumption and standing scores among these 4 groups( P > 0. 05). After the depressive models were established,at the age of 14 weeks before light-intervention,in rats of these 3 intervention groups,the sucrose consumption and standing scores were lower than those of the control group( P < 0. 05),and there was no significant difference found in the above 2 indexes among these 3intervention groups( P > 0. 05). At the age of 20 weeks after light-intervention,the sucrose consumption and standing scores were not significantly different from each other among the 4 groups( P > 0. 05). The peak levels of melatonin in the peripheral blood of rats in these 3 intervention groups were higher than that in the control group. The peak levels onsets of melatonin in peripheral blood of rats in the circadian light group and the energy saving light group were earlier or 2 hours delayed compared to that of control group,while it was similar between the incandescent light group and control group.CONCLUSION: The circadian light,the energy saving light and the incandescent light are similarly effective in improving the behaviors of depressive rats. The circadian light can delay the onset of peak level of melatonin in peripheral blood.
