Abstract
1. During the long history of chicken domestication, eyelid colour, like skin colour and shank colour, has been one of the physical traits of Chinese indigenous chickens that influence consumer buying behaviour. In China, the Lindian chicken, which has coloured feathers, is renowned for the appetizing flavour of its meat and eggs, and its eyelid colours vary from deep (black) to light shades (light yellow). 2. To investigate genes involved in eyelid colour, the expression profiles of black and light-yellow eyelids of Lindian chickens were analysed with transcriptome sequencing. 3. A total of 13 466 genes were detected in the eyelids, among which 14 were differentially expressed. Among these differentially expressed genes (DEGs), three key genes, premelanosome protein (PMEL), dopachrome tautomerase (DCT), and tyrosinase (TYR), encoded proteins that positively regulate melanogenesis and melanin deposition. PMEL, DCT and TYR were expressed much more strongly in the black eyelids than in the light-yellow eyelids. A Kyoto Encyclopedia of Genes and Genomes pathway analysis showed that tyrosine metabolism and melanogenesis genes were significantly enriched among these DEGs (corrected P < 0.05). 4. In conclusion, melanin may be one of the main factors involved in Lindian chicken eyelid colour. Furthermore, these results provide a valuable resource for the future study of the physical traits of Lindian chicken.

Abstract
Pro-opiomelanocortin (POMC) neurones within the hypothalamic arcuate nucleus are vital anorexigenic neurones. Both the insulin receptor and leptin receptor are coupled to activation of phosphatidylinositide-3 kinase (PI3K) to regulate multiple functions that increase POMC neuronal excitability. Using whole-cell recording in several mammalian species, we have found that both insulin and leptin depolarised POMC neurones via activation of transient receptor potential (TRPC)5 channels. TRPC5 channels have been rigorously characterised as the downstream effector based on their biophysical properties, pharmacological profile, and localisation by immunocytochemistry and single-cell reverse transcriptase-polymerase chain reaction. By contrast, insulin and leptin hyperpolarise and inhibit neuropeptide Y/agouti-related peptide neurones via activation of KATP channels. As proof of principle, insulin given i.c.v. robustly inhibits food intake and increases O2 utilisation, CO2 production and metabolic heat production. Therefore, these findings indicate that the depolarisation/excitation of POMC neurones by insulin and leptin is preserved across mammalian species and the activation of TRPC5 channels is likely a major mechanism by which insulin and leptin regulate energy homeostasis in mammals.

Abstract
Nicotinic acid (NA) is ubiquitous in nature and its microbial degradation mechanisms are diverse. In this study, Pusillimonas sp. strain T2 was found to be capable of utilizing NA as sole carbon and nitrogen sources. This strain could completely degrade 300 mg l-1 NA within 3·5 h at 30°C and pH 7·0 and one of the degradation intermediate of NA was identified as 6-hydroxynicotinic acid (6HNA). The draft genome sequences of strain T2 were determined to have a total length of 3·3 M bp and 3054 proteins were predicted. The encoding genes of three-component NA hydroxylase (NahAB1 B2 ) genes were identified. The nahAB1 B2 genes were heterologously expressed in the non-NA-degrading Shinella sp. strain HZN7. The recombinant HZN7-pBBR-nahAB1 B2 converted NA into equimolar 6HNA, while the recombinants HZN7-pBBR-nahAB1 (lacking component B2 ) and HZN7-pBBR-nahAB2 (lacking component B1 ) could not convert NA. Cell-free extracts of HZN7-pBBR-nahAB1 B2 exhibited NA hydroxylase activity. After addition of an artificial electron acceptor (such as phenazine methosulphate, PMS), the NA hydroxylase activity was significantly increased. The Km and Vmax values for NA were 65·94 μmol l-1 and 260·80 ± 5·69 mU mg-1 , respectively, using PMS as an electron acceptor. This study provides a novel insight into the NA degradation by bacteria. SIGNIFICANCE AND IMPACT OF THE STUDY Nicotinic acid (NA) serves as a model system for the degradation of N-heterocyclic aromatic compounds and the microbial degradation mechanisms are diverse. This is the first time that a three-component hydroxylase has been identified. This study provides a novel insight into the NA degradation by bacteria.

Abstract
Recent studies have shown that expression levels of different alleles at the same HLA class I locus can vary dramatically, which might have a broad influence on human disease. However, precise quantification of the relative expression level of each HLA allele is challenging, because distinguishing different alleles on the same locus is difficult. Here, we developed a series of allele-specific, real-time polymerase chain reaction assays for quantifying HLA class I allele mRNA in most Han individuals. The alleles of almost all heterozygous genotypes with a frequency higher than 0.5% in our population (78 alleles on HLA-A locus, 124 alleles on HLA-B locus, and 74 alleles on HLA-C locus) were specifically amplified. The specificity of the amplification was strictly validated by setting the corresponding negative control for each allele of each genotype. The amplification efficiency of each reaction was determined, and the slopes of the reactions were compared. This study provides a tool for detecting the comprehensive expression profile of HLA class I alleles and will be useful not only for the investigation of the molecular mechanism underlying HLA allele expression regulation but also for exploration of immunological mechanisms involving HLA expression in the fields of tumour immune evasion, viral infection, auto-immune disorders, and graft vs host disease after haematopoietic stem cell transplantation.

Abstract
Objective: To analyze the clinical features and the pathogenetic law of traumatic optic neuropathy through epidemiologic study. Methods: 265 cases (275 eyes) with TON treated in Department of Otorhinolaryngology Head and Neck Surgery, the Affiliated Hospital of Qingdao University from April 1999 to August 2015 were retrospectively analyzed. Multiple Logistic regression analyses were used to evaluate potential prognostic factors on visual acuity. Results: TON occured mostly in young (194/265, 73.21%) man (235/265, 88.68%), the majority of patients came from villages and towns (209/265, 78.87%). Traffic accident (197/265, 74.34%) remained the main etiology, with strike (36/265, 13.58%) and fall (17/265, 6.42%) as the common etiology. Most patients had head injuries. The effective rate of vision improvement was 53.45%(147/275). Multiple logistic regression analyses identified that initial visual acuity with light perception or better vision, optic canal fracture and orbital wall fracture were visual acuity key factors of TON (χ(2) value was 24.674, 19.755, 9.175, respectively, all P<0.01), initial visual acuity with light perception or better vision was the protective factor on visual acuity recovery (OR=5.008, P<0.001), the presence of optic canal fracture and orbital wall fracture were the risk factors on visual acuity recovery (OR value was 0.110, 0.329, respectively, all P<0.01). Conclusions: Ton occurs mostly in young man because of traffic accident. Visual impairment of TON is severe. The suitable preventive measures should be carried out according to its epidemiological features.

Abstract
OBJECTIVE To examine the ability of an extract from traditional Chinese medicine, Polygonum multiflorum Radix, to protect melanocyte viability from oxidative stress, a key mechanism in the initiation and progression of hair greying. METHODS To assess the antioxidant capacity of Polygonum multiflorum Radix extract, primary human foreskin melanocytes were treated with a commercially available Polygonum multiflorum Radix extract added to culture medium and exposed to hydrogen peroxide (H2 O2 ), using intracellular reactive oxygen species concentrations and glutathione/protein ratios as endpoints. To improve solubility for cosmetic uses, a new Polygonum multiflorum Radix extract was derived. As hair greying is the consequence of melanocyte disappearance in an oxidative stress environment, we checked whether the antioxidant capacity of the new Polygonum multiflorum Radix extract could preserve melanocyte viability in response to H2 O2 -induced oxidative stress, and preserve pigmentation within ex vivo human hair follicles. RESULTS In vitro treatment of primary human foreskin melanocytes with traditional available Polygonum multiflorum Radix extract resulted in decreased intracellular ROS accumulation in response to H2 O2 exposure with a concomitant preservation of glutathione-to-protein ratio, consistent with a protective response against H2 O2 exposure and demonstrating the promise of this extract for protecting melanocytes against oxidative stress. Melanocytes treated with the improved Polygonum multiflorum Radix extract exhibited attenuated H2 O2 -induced cell death, demonstrating a clear cytoprotective effect. Treatment of ex vivo human hair follicles with the improved Polygonum multiflorum Radix extract resulted in a higher level of melanin compared to vehicle-treated controls, demonstrating an ex vivo protective effect on hair pigmentation. CONCLUSION Polygonum multiflorum Radix extract protects in vitro primary human foreskin melanocytes from the deleterious effects of H2 O2 exposure and improves pigmentation within ex vivo human hair follicles, demonstrating the utility of Polygonum multiflorum Radix extract as a potential active ingredient for the protection of melanocytes against premature death. This data provides in vitro mechanistic evidence consistent with existing in vivo studies for the use of Polygonum multiflorum Radix extract as a strategy for the prevention of oxidative stress-induced hair greying, in line with traditional Polygonum multiflorum Radix uses.

Abstract
Recently, transcriptome and proteome data have increasingly been used to identify potential novel genes related to insect phenotypes. However, there are few studies reporting the large-scale functional identification of such genes in insects. To identify novel genes related to fecundity in the brown planthopper (BPH), Nilaparvata lugens, 115 genes were selected from the transcriptomic and proteomic data previously obtained from high- and low-fecundity populations in our laboratory. The results of RNA interference (RNAi) feeding experiments showed that 91.21% of the genes were involved in the regulation of vitellogenin (Vg) expression and may influence BPH fecundity. After RNAi injection experiments, 12 annotated genes were confirmed as fecundity-related genes and three novel genes were identified in the BPH. Finally, C-terminal binding protein (CtBP) was shown to play an important role in BPH fecundity. Knockdown of CtBP not only led to lower survival, underdeveloped ovaries and fewer eggs laid but also resulted in a reduction in Vg protein expression. The novel gene resources gained from this study will be useful for constructing a Vg regulation network and may provide potential target genes for RNAi-based pest control.
