Abstract
This was a pilot study aiming to evaluate the effects of probiotics as adjunctive treatment for ulcerative colitis (UC). Twenty-five active patients with UC were assigned to the probiotic (n = 12) and placebo (n = 13) groups. The probiotic group received mesalazine (60 mg kg-1 day-1 ) and oral probiotics (containing Lactobacillus casei Zhang, Lactobacillus plantarum P-8 and Bifidobacterium animalis subsp. lactis V9) twice daily for 12 weeks, while the placebo group received the same amounts of mesalazine and placebo. The clinical outcomes were assessed. The gut mucosal microbiota was profiled by PacBio single-molecule, real-time (SMRT) sequencing of the full-length 16S rRNA of biopsy samples obtained by colonoscopy. A significantly greater magnitude of reduction was observed in the UC disease activity index (UCDAI) in the probiotic group compared with the placebo group (P = 0.043), accompanying by a higher remission rate (91.67% for probiotic-receivers versus 69.23% for placebo-receivers, P = 0.034). The probiotics could protect from diminishing of the microbiota diversity and richness. Moreover, the gut mucosal microbiota of the probiotic-receivers had significantly more beneficial bacteria like Eubacterium ramulus (P < 0.05), Pediococcus pentosaceus (P < 0.05), Bacteroides fragilis (P = 0.02) and Weissella cibaria (P = 0.04). Additionally, the relative abundances of the beneficial bacteria correlated significantly but negatively with the UCDAI score, suggesting that the probiotics might alleviate UC symptoms by modulating the gut mucosal microbiota. Our research has provided new insights into the mechanism of symptom alleviation in UC by applying probiotic-based adjunctive treatment.

Abstract
Clinical and subclinical bovine mastitis are the most frequent diseases encountered on dairy farms worldwide, which cause significant economic loss and veterinary cost. The mastitic disease status is associated with increases in both milk bacterial pathogens and somatic cell count (SCC). Although it is well established that the mastitic pathogens generally correlate with the milk SCC, to our knowledge, the correlation between the probiotic genus, Lactobacillus, and the mastitic causative bacteria and SCC have not been determined previously. Thus, in this study, milk samples from 12 mild and 28 severe subclinical mastitic dairy cows were collected from the same farm. The overall milk bacterial load was quantified with the total plate count method. The Lactobacillus genus and 4 common clinical and subclinical mastitic pathogens (Escherichia coli, Staphylococcus aureus, Streptococcus agalactiae, and Trueperella pyogenes) in the sampled milk were enumerated by quantitative PCR. Mild and severe subclinical mastitic samples were distinctly separated on the principal component analysis score plot generated based on the quantities of these 5 target bacteria, suggesting that clear differences existed in the microbiological composition between the two sample groups. Based on comparison with the pairwise Mann-Whitney test, the mild subclinical mastitic dairy cows had a significantly higher amounts of lactobacilli (P=0.0175), but lower E. coli (P=0.0002), S. aureus (P<0.0001), S. agalactiae (P=0.0001) and T. pyogenes (P=0.0044) quantities, while an opposite trend occurred in the severe subclinical mastitic group. The negative correlation between Lactobacillus and the pathogenic bacteria, as well as the SCC, was confirmed with Spearman correlation analysis. Data generated from the current study may hint to a close relationship between Lactobacillus and the health of bovine udder.

Abstract
The Mongolian nationality has developed their unique lifestyle and dietary habit for thousands of years. However, by now, little research has been focused on Mongolian gut microbiota and how it is related to different dietary habits. In this study, denaturing gradient gel electrophoresis (DGGE) and quantitative polymerase chain reaction (qPCR) methods were applied to reveal the diversity of predominant gut bacteria of 48 healthy Mongolians recruited from Hohhot city and the Xilin Gol pasturing area in Inner Mongolia. Compared to similar studies of other nationalities, results from the present study have confirmed that the composition of Mongolian gut microbiota is highly similar at the phylum level (Firmicutes, Bacteroidetes, Proteobacteria and Actinobacteria) but variable at the genus level. Especially, the numbers of Phascolarctobacterium, Lactobacillus and Bifidobacterium are rather high. DGGE profiles of Lactobacillus and Bifidobacterium revealed that Lactobacillus casei, Bifidobacterium longum and Bifidobacterium animalis subsp. lactis were predominant in the gut of the Mongolian subjects studied. On the contrary, Lactobacillus helveticus was detected in every pasturing area Mongolian, but not in any of the Hohhot city Mongolians. qPCR results revealed that the numbers of Lactobacillus and Bifidobacterium of Xilin Gol Mongolians were significantly higher (P<0.05) than that of Hohhot Mongolians, whereas the numbers of Enterobacterium were significantly lower (P<0.05). In addition, by partial least squares discriminate analysis and cluster analysis of data generated from DGGE and qPCR experiments, a striking difference in the composition of intestinal microbiota of Mongolians living in Hohhot city and the Xilin Gol pasturing area has been found. This study clearly shows that diet affects the microbiota composition of Mongolians living in different circumstances, i.e. urban versus rural.

Abstract
OBJECTIVE Our purpose was to determine whether Erb's palsies occurring in the absence of shoulder dystocia differ from those occurring after shoulder dystocia. STUDY DESIGN We compared the time course of resolution and incidence of persistent injury at 1 year of age in 17 cases of Erb's palsy without shoulder dystocia and 23 cases associated with shoulder dystocia. RESULTS The rate of persistence at 1 year was significantly higher in those Erb's cases without identified shoulder dystocia, 7 of 17 (41.2%) versus 2 of 23 (8.7%), p = 0.04. These cases of Erb's palsies also took longer to resolve (6.4 +/- 0.9 vs 2.6 +/- 0.7 months, p = 0.002), had a higher rate of associated clavicular fracture (12 of 17 vs 5 of 23, p = 0.006), and were more likely to occur in the posterior arm (10 of 15 vs 4 of 21, p = 0.009). CONCLUSIONS Erb's palsy occurring without shoulder dystocia may be a qualitatively different injury than that occurring with shoulder dystocia.
