Abstract
Complete mitochondrial DNA D-loop sequences of 1105 individuals were used to assess the diversity of maternal lineages of cattle populations in China. In total, 250 taurine and 88 zebu haplotypes were identified. Five main haplogroups-T1a, T2, T3, T4 and T5-were identified in Bos taurus, whereas Bos indicus harbored two haplogroups-I1 and I2. Our results suggest that the distribution of T1a in Asia was concentrated mainly in the northeast region (northeast China, Korea and Japan); haplogroups T2, T3 and T4 were predominant in Chinese cattle; and T5 was sporadically detected in Mongolian and Pingwu cattle. In contrast to the widespread presence of I1, I2 was distributed only in southwestern China (Yunnan-Guizhou Plateau and the Tibet Autonomous Region) and Xinjiang Uygur Autonomous Region. This is the first time that all five taurine haplogroups and two zebu haplogroups have been found in Mongolian cattle. In addition, eight individuals in Tibetan cattle carried the Bos grunniens mtDNA type. The high mtDNA diversity (H = 0.904 ± 0.008) and the weak genetic structure among the 57 Chinese cattle breeds/populations are consistent with their complex historical background, migration route and ecological environment.

Abstract
Sumac is universally known for its abundance of raw lacquer. Toxicodendron vernicifluum (Stokes) F.A. Barkley is one of the widely distributed native sumac cultivars. To accelerate sumac breeding for more prolific, high-quality, and robust cultivars, it is essential to explore its lacquer metabolism. However, transcriptomic and genomic data available for sumac are still limited. In this study, we generated the transcriptomic profiles of triploid Toxicodendron vernicifluum CV. Dahongpao (Dahongpao) and diploid T. vernicifluum and Toxicodendron vernicifluum CV. Huoyanzi (Huoyanzi), with 87856 unigenes. About 53% of these unigenes were annotated using Nr, Swiss-Prot, Kyoto Encyclopedia of Genes and Genomes (KEGG), Cluster of Orthologous Groups (COG) and Gene Ontology (GO). We identified nine differentially expressed candidate genes associated with type III polyketide synthase formation, which is the first step in urushiol biosynthesis. Additionally, a number of simple sequence repeats (EST-SSRs) were identified in T. vernicifluum for further molecular marker-assisted breeding. This study is the first report of Toxicodendron species transcriptome.

Abstract
Objective: To compare the use of cone beam computed tomography (CBCT) and conventional approach (clinical probing and periapical radiograph) in assessing furcation involvement (FI) of maxillary molars and making treatment decisions. Methods: Thirty-two subjects were selected from the pool of patients at the Department of Periodontology, Tianjin Stomatology Hospital & Hospital of Stomatology, NanKai University from January 2015 to December 2016. All the patients have a diagnosis of generalized chronic periodontitis. Ninety-five maxillary molar with FI from the radiography database were analysed. Two doctors used conventional approach and CBCT images to assess FI and make treatment decision respectively. If the clinical and radiographic findings did not clearly indicate a distinct periodontal therapy, two treatment options were considered. Results: There was statistical difference of the FI diagnosis between traditional group and CBCT group assessment of the 95 molars (P=0.000). Thirty-five maxillary molars (36.8%, 17 patients) got two treatment recommendations by conventional approach but 7 (7.4%, 5 patients) by CBCT-based approach. When with the less invasive treatment recommendation, there was statistical difference between conventional approach and CBCT-based approach (P=0.001). An agreement was observed in 63.2% (60/95) of the teeth, while in another 29.5% (28/95) the CBCT-based treatment decision was more invasive than the conventional approach. When with the more invasive treatment recommendation, there was also statistical difference between two approaches (P=0.045). An agreement was observed in 86.3% (82/95) of the teeth, while in another 3.2% (3/95) the CBCT-based treatment decision was more invasive than the conventional approach. Conclusions: CBCT images of maxillary molars may provide detailed information of FI and a reliable basis for treatment decision.

Abstract
In the present investigation, the antitumor effect of ferruginol (FGL) in SK-Mel-28 human malignant melanoma cells was studied. To investigate the cytotoxic property of FGL, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay was used. Results revealed that prolonged treatment duration decreases the IC25, IC50, and IC75 concentrations of FGL. The cytotoxicity was further confirmed by lactate dehydrogenase assay. As evident from comet assay, FGL induces DNA damage in a dose-dependent manner. Annexin V and 7-ADD assays showed that FGL-induced DNA damage triggers apoptosis-mediated cell death as confirmed by caspase-3 activity assay. As seen through Western blotting, FGL increases phosphorylation of p38 and nuclear translocation of NF-κB. Further, it was observed that p38 phosphorylation is responsible for NF-κB translocation to the nucleus. Further, inhibition of p38 phosphorylation and translocation of NF-κB decrease caspase-3 activity. The above finding confirms that caspase-3 activation is mediated through P-p38 and nuclear translocation of NF-κB. The present findings indicate that FGL significantly suppresses the proliferation of SK-Mel-28 cells in a dose- and time-dependent manner through induction of apoptosis. Furthermore, FGL executes apoptosis through phosphorylation of key protein such as p38 and translocation of NF-κB into the nucleus.

Abstract
Objective:To compare the diagnostic potential of HE staining, enzymatic histochemistry and immunohistochemistry in displaying lymphatic vessel of laryngeal carcinoma.Method:We recruited 3 patients who were pathologically diagnozed as laryngeal squamous cell carcinoma and were performed total laryngectomy in the First Affiliated Hospital of Shanxi Medical University from April to December 2016. According to the improved Kawamoto's Film Method, frozen specimens of whole laryngeal squamous cell carcinoma were made. Immunohistochemistry, using lymphatic endothelial cell specific marker D2-40, enzymatic histochemistry (5-nucleotidase) and HE staining were used to stain the frozen sections of laryngeal carcinoma. Then the staining results of lymphatic vessels in the specimens of laryngeal carcinoma were compared by the optical microscope. Result:The background of HE and D2-40 immunohistochemical staining were clear.5-Nase staining had a deeper background and more nonspecific staining. By immunohistochemistry,102(97.1%,102/105)blood vessels were identified, and 3(2.9%) were partly positive. While using 5-Nase,56(53,3%,56/105)blood vessels were identified. In 105 lumen structures that could not be clearly judged,95(90,5%)were positive by D2-40,while by 5-Nase staining,89(84.8%)were positive including a large number of glands.In addition, positive cells scattered in dots or clusters were observed in 5-Nase and D2-40 staining sections, but these cells or structures could not be identified by HE staining. Conclusion:D2-40 immunohistochemistry may have certain applied value in the study of lymphatic vessels associated with laryngeal carcinoma.

Abstract
Hepatic glutamate uptake and conversion to glutamine is critical for whole-body N metabolism, but how this process is regulated during growth is poorly described. The hepatic glutamate uptake activities, protein content of system [Formula: see text] transporters (EAAC1, GLT-1) and regulatory proteins (GTRAP3-18, ARL6IP1), glutamine synthetase (GS) activity and content, and glutathione (GSH) content, were compared in liver tissue of weaned Angus steers randomly assigned (n = 8) to predominantly lean (growing) or predominantly lipid (finished) growth regimens. Steers were fed a cotton seed hull-based diet to achieve final body weights of 301 or 576 kg, respectively, at a constant rate of growth. Liver tissue was collected at slaughter and hepatic membranes fractionated. Total (75%), Na+-dependent (90%), system [Formula: see text]-dependent (abolished) glutamate uptake activity, and EAAC1 content (36%) in canalicular membrane-enriched vesicles decreased as steers developed from growing (n = 6) to finished (n = 4) stages, whereas Na+-independent uptake did not change. In basolateral membrane-enriched vesicles, total (60%), Na+-dependent (60%), and Na+-independent (56%) activities decreased, whereas neither system [Formula: see text]-dependent uptake nor protein content changed. EAAC1 protein content in liver homogenates (n = 8) decreased in finished vs. growing steers, whereas GTRAP3-18 and ARL6IP1 content increased and GLT-1 content did not change. Concomitantly, hepatic GS activity decreased (32%) as steers fattened, whereas GS and GSH contents did not differ. We conclude that hepatic glutamate uptake and GS synthesis capacities are reduced in livers of finished versus growing beef steers, and that hepatic system [Formula: see text] transporter activity/EAAC1 content is inversely proportional to GTRAP3-18 content.

Abstract
PurposeTo determine what impact rapid ascension to a high-altitude environment has on the retina with the aim of preventing and treating high-altitude oculopathy.Patients and methodsParticipants in the study were members of the Chinese military assigned to the high-altitude environment of the Tibetan plateau. Ninety-one participants were enrolled in the study. Optical coherence tomography was used to measure the thickness of retina-related indicators. Measurements were taken before and after exposure to the high-altitude environment and upon return to the baseline altitude.ResultsFollowing exposure to the high-altitude environment in Tibet, there was a significant increase in retinal nerve fiber layer (RNFL) thickness in the temporal and nasal quadrants of the optic disc, whilst a significant decrease in RNFL thickness in the inferior optic disc was also observed. A significant increase in RNFL thickness in the superior and inferior macula was also evident, along with a significant increase in the ganglion cell layer thickness in the superior macula. Upon return to the baseline altitude, all measurements returned to baseline levels except for the RNFL of the inferior macula, which was significantly thicker. Pathological changes were also documented in the eyes of nine participants upon returning to baseline altitude, including ischemic optic neuropathy, myopia, and cortical amaurosis.ConclusionsThe high-altitude environment can have a negative impact on the health of the retina and may contribute to the incidence of various eye diseases. This study deepens the understanding of what impact a high-altitude environment has on retina and provides reliable data for blindness prevention and treatment.

Abstract
It is well known that both British and American Pekin ducks originated from China. However, the populations differ substantially in production performance, but the genetic changes involved are still poorly understood. Herein, we sequenced 24 individual Pekin ducks (eight from each population) with an average sequencing depth of more than 45× for each population (mean coverage of 6.29 per individual). Among these populations from three different countries, we identified a large number of SNPs and indels as well as many unique population variants, which can be used as population-specific molecular markers. Genomic comparisons among the three duck populations revealed many candidate genes as well as pathways and Gene Ontology categories that are putatively associated with meat yield in the British population, growth in the American population and brain development in all three populations. These findings will enable a better understanding of the artificial selection history of Pekin ducks and provide a valuable resource for future research on the breeding of this species.

Abstract
OBJECTIVES Sensitive skin (SS) is a condition characterised by high reactivity, low tolerance, and susceptibility to allergies of the skin. Owing to changes in the environment and marketing strategies, as well as the increasing public awareness about skin care, attention to skin condition is gradually increasing. The aim of this study is to explore the differences in the skin barrier of SS and normal skin (NS). METHODS A questionnaire survey was conducted and basic indicators of the skin barrier were analysed. It was found that sebum secretion in the SS group was lower than that in the NS group, suggesting that the development of SS might be associated with sebum secretion and its specific components. Next, an ultra performance liquid chromatography-quadruple time-of-flight mass spectrometer was used to identify facial sebum components in female volunteers. RESULTS The results showed that the sebum of female volunteers with SS had high levels of ceramides, glycerophosphoethanolamines, and diacylglycerols, and low levels of glucosylceramides, glycerophosphoserines, glycerophosphocholines, and triacylglycerols. CONCLUSION Analysis of lipid functions suggested that the main reason for SS development in women might be a barrier dysfunction caused by excessive apoptosis and lack of water. Therefore, anti-allergy additives in cosmetic products that could inhibit apoptosis of keratinocytes and methods to maintain the stability of water molecules in the skin should be further studied.

Abstract
Alveolar epithelia play an essential role in maintaining the integrity and homeostasis of lungs, in which alveolar epithelial type II cells (AECII) are a cell type with stem cell potential for epithelial injury repair and regeneration. However, mechanisms behind the physiological and pathological roles of alveolar epithelia in human lungs remain largely unknown, partially owing to the difficulty of isolation and culture of primary human AECII cells. In the present study, we aimed to characterize alveolar epithelia generated from A549 lung adenocarcinoma cells that were cultured in an air-liquid interface (ALI) state. Morphological analysis demonstrated that A549 cells could reconstitute epithelial layers in ALI cultures as evaluated by histochemistry staining and electronic microscopy. Immunofluorescent staining further revealed an expression of alveolar epithelial type I cell (AECI) markers aquaporin-5 protein (AQP-5), and AECII cell marker surfactant protein C (SPC) in subpopulations of ALI cultured cells. Importantly, molecular analysis further revealed the expression of AQP-5, SPC, thyroid transcription factor-1, zonula occludens-1 and Mucin 5B in A549 ALI cultures as determined by both immunoblotting and quantitative RT-PCR assay. These results suggest that the ALI culture of A549 cells can partially mimic the property of alveolar epithelia, which may be a feasible and alternative model for investigating roles and mechanisms of alveolar epithelia in vitro.

Abstract
IL-37, a newly found anti-inflammatory cytokine of the IL-1 family, has both extracellular and intracellular functions. Accumulating evidences indicate that it is also involved in tumor progression. However, the mechanism and its intracellular target are unclear. In this study, clinical data from 84 patients showed that loss or reduced expression of IL-37 in lung adenocarcinoma tissues was significantly associated with tumor metastasis. We further provided evidence that IL-37 inhibited effectively tumor metastasis in vitro and in vivo. Moreover, we uncovered a novel mechanism by which IL-37 suppressed tumor cell migration via its intracellular mature form (amino acids 46-218). Intracellular mature form of IL-37, but not its extracellular form, markedly inhibited migration of multiple kinds of tumor cells through inhibiting Rac1 activation. Mechanistically, intracellular mature IL-37 directly bound to the CAAX motif in the C-terminal hypervariable region of Rac1, and then inhibited Rac1 membrane translocation and subsequent downstream signaling. Our research identifies intracellular mature IL-37 as a novel endogenous inhibitor of Rac1. Given the crucial roles of Rac1 in tumor angiogenesis and metastasis, intracellular mature IL-37 might serve as a potential strategy for the control of Rac1 activity and tumor progression.

Abstract
Objective: To identify the clinical features of mononucleosis caused by co-infection of Epstein-Barr virus (EBV) and cytomegalovirus (CMV) in adult patients. Methods: A total of 103 inpatients with mononucleosis in Peking University Third Hospital from May 2013 to May 2016 were collected as the study subjects.The patients were divided into three groups according to the responsible pathogens: 33 patients infected with EBV and CMV, 53 infected with EBV alone and 17 infected with CMV alone.Furthermore, a case-control study was employed to retrospectively compare the clinical characteristics and prognosis with χ(2,) t or rank tests. Results: The incidences of sore throat, pharynx congestion, tonsil enlargement, tonsil membrane, lymphadenectasis in co-infected patients were statistically lower than those in EBV-infected patients(χ(2)=19.202-25.492, all P<0.05), and were equivalent to those in CMV-infected patients(χ(2)=0.078-4.381, all P>0.05). The levels of alkaline phosphatase, glutamyl transferase, lactic dehydrogenase, white blood cell count and atypical lymphocyte in co-infected patients were statistically lower than those in EBV-infected patients(t/U=3.471-104.629, all P<0.05), and were similar to those in CMV-infected patients(t/U=0.447-24.330, all P>0.05). The levels of alanine aminotransferase and total bilirubin in co-infected patients were equivalent to those in the other two groups(U=1.695, 6.371, both P>0.05). The duration of fever in co-infected patients[(18±9) d] was between EBV alone [(15±7) d] and CMV alone [(21±7) d]infected patients. Conclusions: Co-infection of EBV and CMV is not uncommon.The clinic manifestation of co-infection is more like CMV infection. Liver injury and duration of fever shows no aggravation.

METHODS The levels of serum CCL19 were measured by enzyme linked immunosorbent assay (ELISA) in 90 patients with SLE and 30 healthy controls. These SLE patients included 75 patients who received treatment with glucocorticoids and disease-modifying anti-rheumatic drug (DMARD) and 15 patients without therapy. The frequencies of peripheral blood B cells and the B cell subsets were assessed in the patients with SLE by flow cytometry. The correlation between the clinical data, laboratory parameters, B cell subset frequencies and serum CCL19 levels were analyzed. Indepen-dent samples t test, paired t test, Pearson and Spearman correlation were used for statistical analyses. RESULTS The levels of CCL19 were markedly higher in the SLE patients without therapy and the patients with therapy than in the health controls[(596.25±409.19) ng/L and (422.90±395.84) ng/L vs. (157.79±125.23) ng/L, all P<0.001]. Serum CCL19 levels in the SLE patients without therapy were higher than the SLE patients who accepted glucocorticoids and DMARD treatment (P<0.05). The levels of serum CCL19 were positively correlated with anti-double stranded deoxyribonucleic acid (dsDNA), anti-nucleosome antibody (AnuA), IgA, IgG and IgM (r=0.38, P=0.007; r=0.332, P=0.029; r=0.519, P=0.007; r=0.461, P=0.018, respectively). Serum CCL19 levels in the SLE patients with photosensitivity, arthritis and secondary Sjögren's syndrome were higher than the SLE patients without photosensitivity, arthritis and secondary Sjögren's syndrome, respectively [(562.25±399.12) ng/L, (565.6±435.24) ng/L and (694.9±531.02) ng/L vs. (394.7±281.42) ng/L, (385.90±325.33) ng/L and (424.8±305.46) ng/L, all P<0.05]. The levels of serum CCL19 were positively correlated with the percentage of CD27-B cells and CD27-IgD-double-negative memory B cells (r=0.519, P=0.007; r=0.461, P=0.018, respectively). However, the levels of serum CCL19 were negatively correlated with the percentage of CD27+ memory B cells and CD27+IgD- switched memory B cells (r=-0.433, P=0.027; r=-0.616, P=0.001, respectively). CONCLUSION The increased serum CCL19 levels in SLE patients were associated with the production of autoantibodies, and CCL19 might be involved in the pathogenesis of SLE by disturbing the homeostasis of B cell subsets.

Abstract
Objective: To investigate the significance of extranodal extension of axillary lymph nodes (ALN-ENE) metastases in post-operative primary invasive breast carcinoma of non-specific type. Methods: Six hundred and thirty-eight invasive breast cancer cases confirmed by postoperative pathological examination were collected from January 2006 to December 2008. The relationship of lymph node metastases and ALN-ENE with other lymph node parameters and patient outcome was analyzed. Results: Among 638 cases, 263 (41.2%) showed axillary lymph node metastases. ALN-ENE was present in 91 cases (36.4%). The rate of ALN-ENE increased with pT stage and tumor size. Five-year recurrence-free survival rate (RFS) and 5-year overall survival rate (OS) was 86.6% and 91.2% respectively for ALN-ENE positive group, and both were lower than ALN-ENE negative group (P<0.01). One hundred and forty-nine patients with 1 to 3 positive lymph nodes had a 5-year RFS of 91.9%, and 5-year OS of 92.3%, less than ALN-ENE negative group (P<0.01). Univariate analysis showed ALN-ENE positively correlated with lymph node metastasis. Multivariate analysis suggested that ENE was associated with increased recurrence risk and shortened recurrence-free and overall survival, especially in patients with 1 to 3 positive lymph nodes; and it was an independent prognostic factor (P<0.01). Conclusions: The number of lymph nodes metastases is an important predictor of survival in breast cancer patients. ALN-ENE is an independent risk indicator for recurrence and overall survival. For patients with 1 to 3 metastatic axillary lymph nodes, ALN-ENE could alter the patient's clinical pathologic staging, and therefore it is an independent prognostic factor.

Abstract
Mesenchymal stem cells (MSCs) have been demonstrated to have promising therapeutic benefits for a variety of neurological diseases; however, the underlying mechanisms are poorly understood. Here, we showed that intravitreal infusion of MSCs promoted retinal ganglion cell (RGC) survival in a mouse model of acute glaucoma, with significant inhibition of microglial activation, production of TNF-α, IL-1β, and reactive oxygen species, as well as caspase-8 and caspase-3 activation. In vitro, MSCs inhibited both caspase-8-mediated RGC apoptosis and microglial activation, partly via the action of stanniocalcin 1 (STC1). Furthermore, we found that microRNA-21a-5p (miR-21) and its target, PDCD4, were essential for STC1 production and the neuroprotective property of MSCs in vitro and in vivo. Importantly, miR-21 overexpression or PDCD4 knockdown augmented MSC-mediated neuroprotective effects on acute glaucoma. These data highlight a previously unrecognized neuroprotective mechanism by which the miR-21/PDCD4 axis induces MSCs to secrete STC1 and other factors that exert neuroprotective effects. Therefore, modulating the miR-21/PDCD4 axis might be a promising strategy for clinical treatment of acute glaucoma and other neurological diseases.

Abstract
OBJECTIVE To assess the associations between depression and incident cancer risk. STUDY DESIGN Systematic review and meta-analysis. METHODS The Cochrane Library, Web of Science, MEDLINE, and PubMed databases were searched to identify studies. The quality of included studies was assessed using the Newcastle Ottawa Scale. Risk ratios (RRs) were used to measure effect size. A random-effects model was applied to synthesize the associations between depression and cancer risk. A forest plot was produced to visually assess RRs and 95% confidence intervals (CIs). Heterogeneity across studies was assessed using the I-squared statistic. A funnel plot was generated to assess potential publication bias, and Egger's regression was applied to test the symmetry of the funnel plot. RESULTS In total, 1,469,179 participants and 89,716 incident cases of cancer from 25 studies were included. Depression was significantly associated with overall cancer risk (RR = 1.15, 95% CI: 1.09-1.22) and with liver cancer (RR = 1.20, 95% CI: 1.01-1.43) and lung cancer (RR = 1.33, 95% CI: 1.04-1.72). Subgroup analysis of studies in North America resulted in a significant summary relative risk (RR = 1.30, 95% CI: 1.15-1.48). No significant associations were found for breast, prostate, or colorectal/colon cancer. The average Newcastle Ottawa score was 7.56 for all included studies. CONCLUSION Our findings showed a small and positive association between depression and the overall occurrence risk of cancer, as well as liver cancer and lung cancer risks. However, multinational and larger sample studies are required to further research and support these associations. Moreover, confounding factors such as cigarette smoking and alcohol use/abuse should be considered in future studies.
