Background Perfluorinated alkyl substances (PFAS) are a class of synthetic organic fluorides, which have adverse health effects on brain function, and limited research has been conducted on their effects on depression. Objective To assess potential correlation between serum PFAS and depression. Methods Using the 2015—2016 and 2017—2018 National Health and Nutrition Examination Survey (NHANES) datasets, 2626 subjects with complete relevant information in people ≥20 years old were selected. Logistic regression and restricted cubic splines were used to analyze the association and dose-response relationship between serum PFAS concentration and depression. Subgroup analysis was performed on sex, age, race, education level, marital status, family income to poverty ratio, moderate exercise, body mass index, and drinking status. Results Among the 2626 subjects, there were 666 patients (25.4%) with mild or above depression. After adjusting for race, education level, marital status, body mass index, moderate exercise, drinking history, cotinine, and other types of PFAS, serum perfluorooctane sulfonate (PFOS) was positively associated with the risk of depression (OR=1.85, 95%CI: 1.14, 3.02), and showed a nonlinear dose-response relationship (χ2=6.37, Pnonlinear=0.012). Perfluorononanoic acid (PFNA) was inversely associated with the risk of depression (OR=0.23, 95%CI: 0.14, 0.39), and showed a linear dose-response relationship (Ptrend<0.001, χ2=35.13, Poverall<0.001). After subgroup analysis, it was found that males, 20-39 year-olds and 40-64 year-olds were more sensitive to PFNA exposure (OR=0.15, 95%CI: 0.06, 0.37; OR=0.16, 95%CI: 0.06, 0.40; OR=0.18, 95%CI: 0.08, 0.39). PFOS only showed a statistically significant health effect in people aged 20-39 years (OR=3.00, 95%CI: 1.14, 7.94). In addition, among subgroups of non-Hispanic blacks, cohabitants, current drinkers, high school graduates, and obese patients, exposure to PFAS was significantly associated with the risk of depression. Conclusion PFOS exposure may be associated with increased levels of depression, whereas PFNA exposure may be protective.

Objective: To observe the effect of acupuncture on the intestinal flora in Parkinson disease (PD) model mice and explore the mechanism of acupuncture in improving the locomotor function in PD. Methods: Thirty-two C57BL/6 mice were randomly divided into a control group, a 1-methyl-4-phenyl-1,2,3,6- tetrahydropyridine (MPTP) group, a MPTP + acupuncture group (MPTP+A), and a MPTP + madopar group (MPTP+M), with 8 mice in each group. Except for the control group, the other groups were intraperitoneally injected [25 mg/(kg·bw)] with MPTP to establish PD mouse models. After successful modeling, the MPTP group received no intervention, the MPTP+A received acupuncture at Tianshu (ST25), Guanyuan (CV4), and Zusanli (ST36), and the MPTP+M was given madopar [125 mg/(kg·bw)] by intragastric gavage. After consecutive 10-day interventions, the intestinal function and behaviors of the mice were detected. The 16S rRNA gene sequence was used to analyze the composition of fecal intestinal flora in each group. Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) and enzyme-linked immunosorbent assay were used to detect the expression levels of inflammatory cytokines in the brain and serum. The expression levels of tyrosine hydroxylase (TH) and α-synuclein in the substantia nigra (SN) were detected by immunohistochemical staining. Toll-like receptor (TLR) 2 and lipopolysaccharide receptor CD14 (CD14) in the SN were determined by RT-qPCR. Myeloid differentiation factor (MyD) 88, nuclear factor kappa-B (NF-κB) and Akt1 in the SN were detected by Western blotting. Results: After the intervention, compared with the control group, the intestinal motility, fecal water content, and the expression of TH in the SN were significantly decreased in the MPTP group (P<0.05), along with an increased α-synuclein expression (P<0.05). Additionally, the results of the fecal microflora test showed that the alpha diversity of the MPTP decreased, and the levels of inflammatory cytokines [tumor necrosis factor (TNF)-α, inducible nitric oxide synthase (iNOS), interleukin (IL)-1β, and IL-6] in the serum and SN, and the expression of NF-κB in the SN were significantly increased (P<0.05). Compared with the MPTP group, acupuncture intervention significantly enhanced the autonomous horizontal movement and coordination ability of PD mice (P<0.05); acupuncture and madopar interventions significantly reduced the levels of α-synuclein, inflammatory cytokines (TNF-α, iNOS, IL-1β, and IL-6) in the serum and SN, and the NF-κB expression in the SN, along with significantly increased alpha diversity richness index (P<0.05). In addition, the relative abundance of Bacteroides increased significantly in the MPTP+A (P<0.05), while the relative abundance of Firmicutes and Cyanobacteria decreased significantly (P<0.05). Conclusion: Acupuncture intervention can improve locomotor function, reduce α-synuclein aggregation and inflammatory factors expression, and increase the Akt signaling pathway in PD mice. In addition, acupuncture intervention can benignly regulate the intestinal flora of PD mice. Therefore, it suggests that acupuncture intervention can protect PD model mice probably by regulating intestinal flora and activating Akt signaling pathway.

BACKGROUND:
Parkinson's disease is a neurodegenerative disorder, and recent studies suggested that oxidative stress contributes to the degeneration of dopamine cell in Parkinson's disease. Glutamine also has a positive role in reducing oxidative stress damage. In this study, we hypothesized that glutamine offers protection against oxidative stress injury in 1-methyl-4-phenylpyridinium (MPP)-induced Parkinson's disease cell model.
METHODS:
MPP was used to induce PD models in PC12 cells and classified into control, M0 (MPP), G0 (glutamine), and M0+G0 groups. CCK-8 and AO/EB staining assays were used to examine cell proliferation and apoptosis, respectively. Western blotting was applied to examine the protein expression of PI3K, P-Akt, Akt, P-mTOR, and mTOR.
RESULTS:
We showed that glutamine suppressed cytotoxicity induced by MPP in PC12 cells. MPP decreased the superoxide dismutase and glutathione peroxidase activity and increased the malondialdehyde content, which were restored by glutamine. Moreover, MPP increased the expression of PI3K, P-Akt, Akt, P-mTOR, and mTOR, which were inhibited by glutamine. And the antioxidant capacity of glutamine on PC12 cells could be improved by LY294002 and inhibited by IGF-1.
CONCLUSION
These results suggest that glutamine strengthens the antioxidant capacity in PC12 cells induced by MPP through inhibiting the activation of the PI3K/Akt signaling pathway. The effects of glutamine should be investigated and the protective mechanism of glutamine in PD must be explored in future studies.

Objective To investigate the prevalence of mcr-1 gene,a plasmid-mediated polymyxin resistance gene,in Escherichia coli(E.coli) strains isolated in Dongyang of Zhejiang Province and to under-stand the epidemiological characteristics of E.coli strains carrying mcr-1 gene in order to provide local clini-cians with a theoretical basis for prevention and control of the spread of mcr-1-bearing E.coli strains. Meth-ods A total of 315 E.coli strains were collected in the People′s Hospital of Dongyang, Zhejiang Province from January to December 2016. All strains were isolated from specimens of blood,urine,respiratory tract, etc. PCR was performed to detect the genes confering resistance to polymyxin (mcr-1 gene), β-lactamase and carbapenem. Minimal inhibitory concentrations (MIC) of antibiotics against mcr-1-positive strains were determined by micro-broth dilution method. Conjugation test was performed to confirm whether the mcr-1 gene was located on the transferable plasmid. Multilocus sequence typing (MLST) was used for molecular typing of mcr-1-positive strains. Results Five mcr-1-positive strains were identified from 315 E.coli strains with a positive rate of 1.6%. Two out of the five mcr-1-positive E.coli strains contained β-lactamase resist-ance genes,blaTEM-1and blaCTX-M-14. Both of them were resistant to the first, second and third generation of cephalosporins and one was also resistant to cefepime. All of the five mcr-1-positive E.coli strains were sen-sitive to ciprofloxacin and levofloxacin,but resistant to ticarcillin/clavulanic acid. No carbapenem resistance genes were detected. One transconjugant was successfully obtained by transconjugation assay. MLST analysis showed that a total of four sequence types were identified, including ST131 (two strains), ST43 (one strain),ST69 (one strain) and ST349(one strain). Conclusion Only 1.6% of all E.coli strains isolated in Dongyang area of Zhejiang Province carry mcr-1 gene,indicating that there is no epidemic of mcr-1 gene-positive E.coli infection. The coexistence of mcr-1 gene and β-lactamase resistance genes in E.coli strains isolated in Dongyang suggests that local clinicians should avoid antibiotic abuse to prevent the spread of drug-resistant E.coli.

Objective To analyze the genomic sequences of Cryptococcus neoformans var grubii strains of two genotypes with different virulence and to screen out the virulence-associated genes. Methods A clinical strain (IFM56800) with the strongest virulence and an environmental strain (IFM56731) with the weakest virulence were screened out for whole genome sequencing analysis. The results of sequencing analy-sis were comprehensively analyzed by using the method of comparative genomics. Genetic variations were ex-tensively screened by using the strategies of non-synonymous single nucleotide polymorphisms ( nsSNPs), nonsense SNPs and the insertions or deletions ( InDels) causing frameshift mutations. The filtered genes were sequenced in 20 experimental strains. The whole RNAs were extracted and then the full-length cDNAs were sequenced by using the rapid amplification of 5′ and 3′ cDNA ends (RACE) method. Results By whole genome sequencing, valid data with high coverage (127 times and 111 times) was obtained in both the environmental strain IFM56731 and the clinical strain IFM56800. The data of InDels and SNPs were statisti-cally analyzed, respectively. Six genes were chosen for further analysis based on the strategies of nonsense SNPs and the InDels causing frameshift mutations. The six genes were amplified and sequenced in all of the experimental strains, three of which were further analyzed with cDNA sequencing. Ultimately, the location and structure of CNAG_01032 gene were determined. The predicted nonsense mutation locus was verified to present in the actual mRNA. Conclusion The strategies of nonsense SNPs and the InDels causing frame-shift mutations showed high-efficiency in screening potential virulence-associated genes. The CNAG_01032 gene was screened out as a novel virulence-associated gene.
