Abstract
Objective: To explore the SNP effects of patatin-like phospholipase domain which containing 3 (PNPLA3), transmembrane 6 superfamily member 2 (TM6SF2) gene, environmental effects of smoking, alcohol drinking and interaction between gene-gene, gene-environment and drinking-smoking on hepatitis B virus-associated hepatocellular carcinoma (HBV-HCC). Methods: We collected anticoagulant peripheral blood from patients of HBV-HCC, chronic hepatitis B (CHB), liver cirrhosis (LC) and from healthy controls to detect the single nucleotide polymorphism (SNP) of patatin-like phospholipase domain containing 3 (PNPLA3) gene loci rs738409 and transmembrane 6 superfamily member 2 (TM6SF2) gene loci rs58542926, using the flight mass spectrometry method. The optimal assignment value of gene polymorphisms was defined by using the online SNP stats. Hardy-Weinberg (H-W) balance was tested for SNP. Effects of the genetic and environmental factors to HBV-HCC were analyzed by using the multiple classification logistic regression method. The gene-gene, gene-smoking and alcohol drinking interaction effects were investigated by Fork-Life analysis and binary logistic regression methods. Results: The frequency distribution of CHB group rs738409 loci seemed not in conformity with the H-W balance (χ(2)=11.980, P<0.005). Two loci frequency distributions in the other groups were all in accordandce with the H-W balance. After adjusting for influences on age and sex and comparing to the healthy group, the rs58542926 mutation appeared as OR=1.659, 95%CI: 1.026-2.684, P=0.039, in the HBV-HCC group. When comparing to CHB group, the HBV-HCC group presented that drinking as OR=1.680, 95%CI: 1.121-2.519, P=0.012. When comparing to the LC group, the ORs of drinking and smoking were 1.539 (1.071-2.213) and 1.453 (1.005-2.099) respectively, in the HBV-HCC group. When comparing to the CHB+LC group, interactions between the HBV-HCC group were found rs738409 and rs58542926 on additive model OR=1.548 (U=1.885, P=0.029) and OR=1.658 (P=0.024) on logistic regression model while drinking was rs738409 on interaction additive model with OR=1.811(U=1.965, P=0.024). As for drinking and mutation of rs738409, the multiplication model of logistic regression showed no statistically significant differences. Interaction between smoking and drinking appeared as OR=1.756 (P<0.001) in the logistics regression multiplication model. Conclusions: Factors as mutation of TM6SF2, smoking and drinking all appeared as risk factors for HBV-HCC. Mutations of both PNPLA3 and TM6SF2, together with smoking and drinking all served as risk factors for HBV-HCC. However, the mutation of single PNPLA3 appeared as a protective factor on HBV-HCC.

Abstract
Reference genomes are essential for metagenomic analyses and functional characterization of the human gut microbiota. We present the Culturable Genome Reference (CGR), a collection of 1,520 nonredundant, high-quality draft genomes generated from >6,000 bacteria cultivated from fecal samples of healthy humans. Of the 1,520 genomes, which were chosen to cover all major bacterial phyla and genera in the human gut, 264 are not represented in existing reference genome catalogs. We show that this increase in the number of reference bacterial genomes improves the rate of mapping metagenomic sequencing reads from 50% to >70%, enabling higher-resolution descriptions of the human gut microbiome. We use the CGR genomes to annotate functions of 338 bacterial species, showing the utility of this resource for functional studies. We also carry out a pan-genome analysis of 38 important human gut species, which reveals the diversity and specificity of functional enrichment between their core and dispensable genomes. A resource of >1,500 bacterial reference genomes sheds light on the human gut microbiome.

Abstract
This study compared the effects of sodium selenite and selenium yeast and their combination on laying performance, egg quality, antioxidant capacity, and selenium (Se) contents in tissues and eggs. Two-hundred-eighty-eight Jing Hong layers that were similar in laying rate (87.5 ± 0.38%) and body weight (1.70 ± 0.02 kg) were randomly distributed into 4 treatments for 11 wk (from 203 d old to 279 d old) with 9 replicates of 8 hens per replicate. The diets (corn-soybean meal diet) were supplemented with 0 [blank control (BC)], 0.3 mg/kg Se from sodium selenite (SS), 0.15 mg/kg Se from sodium selenite and 0.15 mg/kg Se from Se yeast (SS+SY), or 0.3 mg/kg Se from Se yeast (SY). Results showed that the laying rate of the SS+SY group increased significantly (P < 0.05) compared to the BC and SY groups. There were no differences (P > 0.05) in egg quality between the Se-supplemented diets and the BC diet. The serum glutathione peroxidase (GSH-Px) activity was increased (P < 0.01) in hens fed Se-supplemented diets compared to the BC diet. The liver superoxide dismutase (SOD) activity of the SY group was increased significantly (P < 0.05) compared to the BC group. Significant increase (P < 0.01) due to SY supplementation was noted in the serum vitamin E content compared to BC and SS. Layers fed Se-supplemented diets had higher (P < 0.01) contents of Se in the serum, liver, and kidney compared to the BC diet. Compared to BC, Se content in eggs was significantly increased (P < 0.05) by feeding supplementary Se. In conclusion, the effects of SS and Se yeast were approximately equal in promoting antioxidant capacity of laying hens, while Se yeast is easier to deposit into eggs and tissues. The diet with added equal amounts of the 2 sources of Se was more cost effective and affordable than a comparable amount of Se yeast to obtain the promising production performance and nearly similar Se deposition.

Abstract
OBJECTIVE To investigate differences in suicide risk among immigrant population in Norway compared with native Norwegians, with respect to associated country group of origin. METHODS Based on the entire national population, a nested case-control design was adopted using Norwegian national longitudinal registers to obtain 23 073 suicide cases having occurred in 1969-2012 and 373 178 controls. Odds ratios (ORs) for suicide were estimated using conditional logistic regression analysis adjusting for socio-economic factors. RESULTS Compared with native Norwegians, suicide risk was significantly lower in first- and second-generation immigrants but higher in Norwegian-born with one foreign-born parent and foreign-born individuals with at least one Norwegian-born parent. When stratifying data by country group of origin, first-generation immigrants had lower ORs in most of the strata. Subjects born in Asia and in Central and South America with at least one Norwegian-born parent had a significantly higher risk of suicide. The observed results remained mostly unchanged in the analyses controlled for socio-economic status. CONCLUSIONS Suicide risk is lower in first- and second-generation immigrants but higher in subjects born in Norway with one foreign-born parent and those born abroad with at least one Norwegian-born parent, with notable differences by country group of origin.

Abstract
Objective: To evaluate the efficacy and safety of maintenance therapy with reduced dose of rhTPO in the patients with primary immune thrombocytopenia (ITP) who attained stable platelet (PLT) counts after daily administration of rhTPO. Methods: Treatment was started with a daily administration of rhTPO (300 U/kg) for 2 consecutive weeks. Patients who attained stable PLT≥50×10(9)/L were enrolled to maintenance therapy starting with every other day administration of rhTPO, then adjusted dose interval to maintain platelet count (30-100) ×10(9)/L. Results: A total of 91 eligible patients were enrolled. Fourteen patients discontinued the study due to noncompliance (12/14) and investigator decision (2/14) . Among 77 patients who completed the study, 38 patients with the administration of rhTPO at every other day or less could maintain PLT≥30×10(9)/L for 12 weeks. The percentage of patients with a platelet response (PLT≥30×10(9)/L) at 4(th) week, 8(th) week and 12(th) week of maintain therapy was 92.6% (63/68) , 82.7% (43/52) and 85.0% (34/40) , respectively. Median platelet counts remained in the range of (70-124) ×10(9)/L. The overall incidence of rhTPO-related adverse events was 7.7%. All the adverse events were generally mild. Conclusion: Extending the dose interval of rhTPO is feasible to maintain stable platelet count in the patients with ITP, but the optimal dose interval is uncertain and might vary with individuals.

Abstract
In this work, a bubble-sheet-like hollow interface design on Al foil anode to improve the cycling stability and rate performance of aluminum anode based dual-ion battery is reported, in which, a carbon-coated hollow aluminum anode is used as both anode materials and current collector. This anode structure can guide the alloying position inside the hollow nanospheres, and also confine the alloy sizes within the hollow nanospheres, resulting in significantly restricted volumetric expansion and ultrastable solid electrolyte interface (SEI). As a result, the battery demonstrates an excellent long-term cycling stability within 1500 cycles with ≈99% capacity retention at 2 C. Moreover, this cell displays an energy density of 169 Wh kg-1 even at high power density of 2113 W kg-1 (10 C, charge and discharge within 6 min), which is much higher than most of conventional lithium ion batteries. The interfacial engineering strategy shown in this work to stabilize SEI layer and control the alloy forming position could be generalized to promote the research development of metal anodes based battery systems.

Abstract
BACKGROUND Psychosocial therapy after deliberate self-harm might be associated with reduced risk of specific causes of death. METHOD In this matched cohort study, we included patients, who after an episode of deliberate self-harm received psychosocial therapy at a Suicide Prevention Clinic in Denmark between 1992 and 2010. We used propensity score matching in a 1:3 ratio to select a comparison group from 59 046 individuals who received standard care. National Danish registers supplied data on specific causes of death over a 20-year follow-up period. RESULTS At the end of follow-up, 391 (6.9%) of 5678 patients in the psychosocial therapy group had died, compared with 1736 (10.2%) of 17 034 patients in the matched comparison group. Lower odds ratios of dying by mental or behavioural disorders [0.54, 95% confidence interval (CI) 0.37-0.79], alcohol-related causes (0.63, 95% CI 0.50-0.80) and other diseases and medical conditions (0.61, 95% CI 0.49-0.77) were noted in the psychosocial therapy group. Also, we found a reduced risk of dying by suicide as well as other external causes, however, not by neoplasms and circulatory system diseases. Numbers needed to treat were 212.9 (95% CI 139.5-448.4) for mental or behavioural disorders as a cause of death, 111.1 (95% CI 79.2-210.5) for alcohol-related causes and 96.8 (95% CI 69.1-161.8) for other diseases and medical conditions. CONCLUSIONS Our findings indicate that psychosocial therapy after deliberate self-harm might reduce long-term risk of death from select medical conditions and external causes. These promising results should be tested in a randomized design.

Abstract
We investigated the genetic diversity of the southern flounder Paralichthys lethostigma. Microsatellite-enriched libraries were constructed and novel microsatellite markers were developed and applied for genetic detection of wild populations. Cross-species amplification was also conducted in five pleuronectiforme species. Of 45 randomly selected and sequenced clones, 43 contained a CA or GA repeat motif. Fourteen pairs of primers were designed to investigate the polymorphism and genetic structure of a wild population collected from North Carolina State coastal waters. Two loci were monomorphic and 12 loci were polymorphic. The number of alleles per polymorphic locus ranged from 2 to 16, with an average of 7.3, and the expected heterozygosity per locus ranged from 0.10 to 0.92, with an average of 0.58. Cross-species amplification showed that most of the markers could successfully amplify Paralichthys olivaceus DNAs, few markers amplified in Verasper variegatus and Verasper moseri, and none of them could amplify Scophthatmus maximus and Cynoglossus semilaevis DNAs. The isolated polymorphic markers would be useful for the genetic breeding and assessment of genetic variation within the genus Paralichthys.

Abstract
BACKGROUND Gaining a greater knowledge of the mechanisms and means by which violent offenders die by suicide can inform tailored preventive strategies. METHODS Using interlinked national Danish registry data we constructed a nested case-control study dataset of all adult suicides during 1994-2006: N=9708 cases and N=188,134 age and gender matched living controls. Completely ascertained International Classification of Diseases 10th revision cause-specific mortality codes were examined, with all criminal charges since 1980, and covariate information on psychiatric treatment and socio-demographics. Self-poisonings were classified as 'nonviolent' suicide and all other methods as being 'violent' ones. RESULTS Compared with the general population, risk among male and female violent offenders was strongly and significantly elevated for suicide by either a violent or a nonviolent method, although the relative risk was greater for nonviolent suicide. These patterns were also observed among nonviolent offenders, albeit with smaller effect sizes. Risk was especially raised for self-poisoning with narcotics & hallucinogens. We could only examine the full range of suicide methods in male violent offenders. In these men, hanging was the most frequently used method, although risk was markedly and significantly elevated virtually across the entire range of regularly used suicide methods. LIMITATIONS We lacked sufficient statistical power for undertaking a detailed profiling of specific suicide methods among female violent offenders. CONCLUSIONS Our findings indicate that comprehensive and broadly-based preventive approaches are needed for tackling the markedly raised risk of suicide by both violent and nonviolent means in this population. Their high relative risk for self-poisoning by illicit or illegal drugs underlines the importance of access to means and of prevailing subculture.

Abstract
OBJECTIVE To examine suicide risk in relation to physical illness across a broad range of illnesses, including hospitalization history, specific organ or system illness and comorbidity. DESIGN A nested case-control study. SETTING Data were retrieved from five Danish national registers. SUBJECTS On the basis of the entire population of Denmark, this study included 27 262 suicide cases, and 468 007 live controls matched for sex and date of birth. MAIN OUTCOME MEASURES Risk of suicide was assessed using conditional logistic regression. RESULTS In the study population, 63.5% of suicide cases and 44.5% of comparison controls had a history of hospitalization for physical illness. A physical illness significantly increased the risk of subsequent suicide (incidence rate ratios 2.13, 95% CI 2.07-2.18) with a substantially greater effect in women than in men (P < 0.01). The elevated risk increased progressively with frequency and recency of hospitalization and was significant for diseases occurring in all organs or systems of the body. Comorbidity involving several organs or systems increased the risk substantially. The associated estimates were to some extent reduced but remained highly significant after adjustment for psychiatric history and socio-economic status. Taking into account both prevalence and adjusted effect size, physical illness accounted for 24.4%, 21.0% and 32.3% of population attributable risk for suicide in total, male and female populations, respectively. CONCLUSIONS Physical illness constitutes a significant risk factor for suicide independent of psychiatric and socio-economic factors. Clinicians treating physically ill patients should be aware of the risk, especially amongst those with multiple or recent hospitalizations, or multiple comorbidities.

Abstract
OBJECTIVE To replicate a previously reported association between pollen counts and county suicide rates in the continental United States, across space and time. METHOD The authors evaluated the relationship between airborne pollen counts and suicide rates in 42 counties of the continental United States, containing a pollen-counting station participating in the Aeroallergen Monitoring Network in the United States (N = 120,076 suicides), considering years' quarter, age group, sex, race, rural/urban location, number of local psychiatrists, and median household income, from 1999 to 2002. The county-level effects were broken into between-county and within-county. RESULTS No within-county effects were found. Between-county effects for grass and ragweed pollen on suicide rates lost statistical significance after adjustment for median income, number of psychiatrists, and urban vs. rural location. CONCLUSION Future research is necessary to reappraise the previously reported relationship between pollen levels and suicide rates that may have been driven by socioeconomic confounders.

Abstract
BACKGROUND With increasing research suggesting a role of allergy on suicidality, this study, on a population level, delved into how allergy affects risk for suicide completion in the context of mood disorder and other factors. METHODS Based on the entire population of Denmark, we included 27,096 completed suicides and 467,571 live controls matched on sex and age with a nested case-control design. We retrieved personal information on hospital contacts for allergy and other variables from various Danish longitudinal registries and analyzed the data with conditional logistic regression. RESULTS We noted that 1.17% suicide victims, compared with 0.79% matched controls, had a history of hospital contact for allergy and that a history of allergy predicted an increased risk for suicide completion; however, the effect was confined to allergy that led to inpatient treatment (IRR: 1.59, 95% CI: 1.41-1.80). The increased risk was attenuated somewhat but remained significant when adjusted for personal psychiatric history and socioeconomic status. Meanwhile, we observed a nonsignificantly stronger effect in women than in men, and a significant age difference with a stronger effect for individuals at high ages. Moreover, we detected a significant interaction between allergy and mood disorder - even an antagonism effect of the two exposures. Allergy increased suicide risk only in persons with no history of mood disorder, whereas it eliminated suicide risk in those with a history of mood disorder. CONCLUSIONS The findings support a link between allergy and suicidality, with a possible mediating role of mood disorder.

Abstract
BACKGROUND Poisoning with weak analgesics is a major public health problem because of easy accessibility of the compounds; however, few studies have investigated their influence on subsequent suicide in the context of subjects' psychiatric status and other factors. METHOD This nested case-control study was based on the entire Danish population including all 21,169 suicide cases and 423,128 matched population controls. Data on hospital admissions for poisoning and confounding factors were retrieved from national medical and administrative registries. Conditional logistic regression was used to compute relative risk. RESULTS A prior hospital admission for poisoning with weak non-opioid analgesics significantly increased the risk of subsequent suicide [crude incidence rate ratio (IRR) 24.7, 95% confidence interval (CI) 22.1-27.6], and the effect of paracetamol poisoning was substantially stronger than that of poisoning with salicylates or non-steroidal anti-inflammatory drugs (NSAIDs). This association could not be explained by confounding from socio-economic or psychiatric factors. The elevated risk was extremely high during the first week following the overdose (adjusted IRR 738.9, 95% CI 173.9-3139.1), then declined over time but still remained significantly high 3 years later (adjusted IRR 4.2, 95% CI 3.5-5.0). Moreover, a history of weak analgesic poisoning significantly interacted with a person's psychiatric history, increasing the risk for subsequent suicide substantially more for persons with no history of psychiatric hospitalization than did it for those with such a history. CONCLUSIONS A history of non-fatal poisoning with weak analgesics is a strong predictor for subsequent suicide. These results emphasize the importance of intensive psychiatric care of patients following overdose.

Abstract
Tibial dyschondroplasia (TD) is characterized by expansion of the proximal growth plates of the tibiotarsus that fail to form bone, lack blood vessels, and contain non-viable cells. Thiram (a carbamate pesticide), when fed to young broiler chicks, induces TD with high regularity and precision. We used this experimental model to understand the cause of the defects associated with TD by selecting and identifying the genes differentially expressed in the TD growth plate of broiler chickens. Broiler chicks at 7 days of age were randomly divided into two groups. After fasting overnight, they were fed with regular diet (control) or the same diet containing 100 mg/kg thiram for 96 h to induce TD (thiram-fed). mRNA was purified from the growth plates of control and thiram-fed broilers. Forward and reverse-subtracted cDNA libraries were generated by suppression subtractive hybridization technology. Ten selected genes from cDNA libraries were identified by real-time quantitative polymerase chain reaction. All were differentially expressed in TD growth plates (P<0.05 or P<0.01). The levels of collagen type X (Col X), pro-alpha-1 collagen type I (Col I alpha1), collagen type IX (Col IX), NADH dehydrogenase (NADH DH), cytochrome C oxidase subunit III (COX III), enolase 1, alpha (ENO1), carbonic anhydrase II (CA2) and heat shock protein 90 (Hsp90) mRNA transcripts were up-regulated, while the expression levels of Matrilin 3 (MATN3) and chondromodulin-I (ChM-I) were down-regulated. Col I and Hsp90 were detected by immunohistochemistry at different stages. Given that these genes are involved in matrix formation, endochondral ossification, developmental regulation, electron transport in the mitochondrial respiratory chain and vascularization, our findings may provide new insights into understanding the pathogenesis of TD.

Abstract
This paper addresses the distribution and occurrence of harmful organic substances in coal gangue dump from Jiulong Coal Mine and its influence on the environment. The samples were taken from the coal gangue dump and coal waste water stream and analyzed by organic geochemical methods. The results indicate that the coal gangues contain abundant harmful organic substances like polycyclic aromatic hydrocarbons. The TOC and sulfur contents of the samples are much higher than those of the background sample except Sample JL7. The contents of organic bulk parameters are relatively high. Ten carcinogenic PAHs were identified and these harmful organic substances have influenced the surrounding area. Along the waste water stream, organic substances pollute at least 1,800 m far from the coal gangue dump.

Abstract
BACKGROUND Many cases of paracetamol poisoning are with suicidal intent, but the association between paracetamol poisoning and subsequent psychiatric disorder is unknown. AIM To examine the association between poisoning with paracetamol or other weak analgesics and subsequent psychiatric disorder. METHODS The study was set in a nested case-control design and based on nationwide Danish registers. We identified all patients diagnosed with schizophrenia, affective disorder or eating disorder in 1994-1998 and matched population controls. We estimated the relative risk of these psychiatric disorders after admission for paracetamol or nonparacetamol poisoning, adjusting for income, employment and marital status. RESULTS We included 12,603 cases with psychiatric disorder, and 1.2% had a diagnosis of poisoning compared with 0.2% of the 252,060 matched population controls. Compared with those with no diagnoses of weak analgesic poisoning, the risk of schizophrenia increased 3.9-fold after paracetamol poisoning, and 2.0-fold after nonparacetamol poisoning. The risk of affective disorder increased 12.2-fold after paracetamol poisoning and 2.6-fold after nonparacetamol poisoning. The risk of eating disorder increased 5.0-fold after paracetamol poisoning, and 2.2-fold after nonparacetamol poisoning. The risk of a diagnosis of psychiatric disorder was very high immediately after poisoning and remained increased for more than 10 years. CONCLUSIONS Paracetamol poisoning is a strong risk marker for psychiatric disorder, particularly affective disorders.

Abstract
OBJECTIVE To investigate the correlation between the free fluid area detected with ultrasonography and the internal hemorrhage volume observed during operation in tubal pregnancy. METHODS The correlation between the size of free fluid area measured by ultrasound and the volume of internal hemorrhage collected during operation among 201 cases of tubal pregnancy was analyzed. The difference of internal hemorrhage between tubal abortion and tubal pregnant rupture was analyzed too. RESULTS A positive correlation was observed between the size of free fluid area measured by ultrasound and the internal hemorrhage volume (r = 0.7712). A statistically significant difference of internal hemorrhage volume was found between tubal abortion and tubal pregnant rupture with a free fluid area in the range of 0.1-10.0 cm. CONCLUSION The volume of internal hemorrhage caused by tubal pregnancy can be estimated according to the free fluid area detected with ultrasonography.
