Abstract
The global transition towards diets high in calories has contributed to 2.1 billion people becoming overweight, or obese, which damages male reproduction and harms offspring. Recently, more and more studies have shown that paternal exposure to stress closely affects the health of offspring in an intergenerational and transgenerational way. SET Domain Containing 2 (SETD2), a key epigenetic gene, is highly conserved among species, is a crucial methyltransferase for converting histone 3 lysine 36 dimethylation (H3K36me2) into histone 3 lysine 36 trimethylation (H3K36me3), and plays an important regulator in the response to stress. In this study, we compared patterns of SETD2 expression and the H3K36me3 pattern in pre-implantation embryos derived from normal or obese mice induced by high diet. The results showed that SETD2 mRNA was significantly higher in the high-fat diet (HFD) group than the control diet (CD) group at the 2-cell, 4-cell, 8-cell, and 16-cell stages, and at the morula and blastocyst stages. The relative levels of H3K36me3 in the HFD group at the 2-cell, 4-cell, 8-cell, 16-cell, morula stage, and blastocyst stage were significantly higher than in the CD group. These results indicated that dietary changes in parental generation (F0) male mice fed a HFD were traceable in SETD2/H3K36me3 in embryos, and that a paternal high-fat diet brings about adverse effects for offspring that might be related to SETD2/H3K36me3, which throws new light on the effect of paternal obesity on offspring from an epigenetic perspective.

Abstract
Polycystic ovary syndrome (PCOS) is an endocrine disorder, affecting women of child-bearing age, and the incidence rate is growing and assuming epidemic proportions. The etiology of PCOS remains unknown and there is no cure. Some animal models for PCOS have been established which have enhanced our understanding of the underlying mechanisms, but omics data for revealing PCOS pathogenesis and for drug discovery are still lacking. In the present study, proteomics analysis was used to construct a protein profile of the ovaries in a PCOS mouse model. The result showed a clear difference in protein profile between the PCOS and control group, with 495 upregulated proteins and 404 downregulated proteins in the PCOS group. The GO term and KEGG pathway analyses of differentially expressed proteins mainly showed involvement in lipid metabolism, oxidative stress, and immune response, which are consistent with pathological characteristics of PCOS in terms of abnormal metabolism, endocrine disorders, chronic inflammation and imbalance between oxidant and antioxidant levels. Also, we found that inflammatory responses were activated in the PCOS ovarium, while lipid biosynthetic process peroxisome, and bile secretion were inhibited. In addition, we found some alteration in unexpected pathways, such as glyoxylate and dicarboxylate metabolism, which should be investigated. The present study makes an important contribution to the current lack of PCOS ovarian proteomic data and provides an important reference for research and development of effective drugs and treatments for PCOS.

Abstract
OBJECTIVES Diet is one of the main risk factors for cardiovascular disease (CVD), while the evidence about the relationship between dietary pattern (DP) and CVD in children is scarce. This study aims to explore the association between DP and CVD risk in children. STUDY DESIGN This was a cross-sectional and longitudinal study. METHODS This research was conducted among 4351 children aged 6-12 years old in 2014, then the subgroup children in 2014 were followed up in 2019. Dietary intakes were assessed using a food frequency questionnaire. DP was clustered based on 15 food items, and finally, four main DPs were obtained. RESULTS Four major DPs were identified: (1) low intake of nuts and algae pattern, (2) low-energy intake pattern, (3) high-energy intake pattern, and (4) regular DP. Compared with the regular diet pattern, the low intake of nuts and algae pattern was associated with the increased risk of higher systolic blood pressure (107.71 mm Hg vs 105.78 mm Hg, P < 0.001), diastolic blood pressure (64.98 mm Hg vs 63.91 mm Hg, P = 0.0056), hypertension (odds ratio [OR]:1.44, 95% confidence interval [CI]: 1.10, 1.88; P = 0.0036), dyslipidemia (OR: 2.41, 95% CI: 1.28, 4.52; P = 0.0194), and obesity (OR: 1.48, 95% CI: 1.16, 1.89; P = 0.0003) in children from a cross-sectional aspect in 2014 and it was also found associated with an increased risk of hypertension (OR: 2.67, 95% CI: 1.45, 4.92; P = 0.0017) in 2019. CONCLUSIONS Low nuts and algae intake combinations in children seemed associated with increased CVD risk. Such findings are imperative for national development of dietary recommendation for the prevention of CVDs.

Abstract
Nonalcoholic steatohepatitis (NASH) prevalence is rising with no pharmacotherapy approved. A major hurdle in NASH drug development is the poor translatability of preclinical studies to safe/effective clinical outcomes, and recent failures highlight a need to identify new targetable pathways. Dysregulated glycine metabolism has emerged as a causative factor and therapeutic target in NASH. Here, we report that the tripeptide DT-109 (Gly-Gly-Leu) dose-dependently attenuates steatohepatitis and fibrosis in mice. To enhance the probability of successful translation, we developed a nonhuman primate model that histologically and transcriptionally mimics human NASH. Applying a multiomics approach combining transcriptomics, proteomics, metabolomics, and metagenomics, we found that DT-109 reverses hepatic steatosis and prevents fibrosis progression in nonhuman primates, not only by stimulating fatty acid degradation and glutathione formation, as found in mice, but also by modulating microbial bile acid metabolism. Our studies describe a highly translatable NASH model and highlight the need for clinical evaluation of DT-109.

Abstract
Obesity is a metabolic disorder resulting from behavioral, environmental and heritable causes, and can have a negative impact on male reproduction. There have been few experiments in mice, rats, and rabbits on the effects of obesity on reproduction, which has inhibited the development of better treatments for male subfertility caused by obesity. Nonhuman primates are most similar to human beings in anatomy, physiology, metabolism, and biochemistry and are appropriate subjects for obesity studies. In this investigation, we conducted a transcriptome analysis of the testes of cynomolgus monkeys on high-fat, high-fructose, and cholesterol-rich diets to determine the effect of obesity on gene expression in testes. The results showed that the testes of obese monkeys had abnormal morphology, and their testes transcriptome was significantly different from that of non-obese animals. We identified 507 differentially abundant genes (adjusted p value < 0.01, log2 [FC] > 2) including 163 up-regulated and 344 down-regulated genes. Among the differentially abundant genes were ten regulatory genes, including IRF1, IRF6, HERC5, HERC6, IFIH1, IFIT2, IFIT5, IFI35, RSAD2, and UBQLNL. Gene ontology (GO) and KEGG pathway analysis was conducted, and we found that processes and pathways associated with the blood testes barrier (BTB), immunity, inflammation, and DNA methylation in gametes were preferentially enriched. We also found abnormal expression of genes related to infertility (TDRD5, CLCN2, MORC1, RFX8, SOHLH1, IL2RB, MCIDAS, ZPBP, NFIA, PTPN11, TSC22D3, MAPK6, PLCB1, DCUN1D1, LPIN1, and GATM) and down-regulation of testosterone in monkeys with dietetic obesity. This work not only provides an important reference for research and treatment on male infertility caused by obesity, but also valuable insights into the effects of diet on gene expression in testes.

Abstract
Somatic cell nuclear transfer (SCNT) is a technology that enables differentiated somatic cells to acquire a totipotent state, thus making it of great value in developmental biology, biomedical research, and agricultural applications. Rabbit cloning associated with transgenesis has the potential to improve the applicability of this species for disease modeling, drug testing, and production of human recombinant proteins. In this chapter, we introduce our SCNT protocol for the production of live cloned rabbits.

Abstract
Somatic cell nuclear transfer (SCNT) shows great application value in the generation of transgenic animals, protection of endangered species, and therapeutic cloning. However, the cloning efficiency is still very low, which greatly restricts its application. Compared to fertilized embryos, cloned embryos lack the sperm proteins, which are considered to play an important role in embryonic development. Here we compared the sperm proteome, with that of donor fibroblasts and oocytes, and identified 342 proteins unique to sperm, with 42 being highly expressed. The 384 proteins were mainly enriched in the categories of post-translational modification and cytoskeletal arrangement. Extracts of soluble sperm or fibroblast proteins were injected into cloned embryos, and the result showed that injection of sperm protein significantly inhibited abnormal embryonic cleavage, significantly decreased the level of trimethylated histone H3Lys9 (H3K9me3) and the apoptotic index, and increased the inner cell mass (ICM)-to-trophectoderm (TE) ratio. More importantly, the sperm proteins also significantly enhanced the birthrate. The results of in vitro and in vivo experiments demonstrate that sperm-derived proteins improve embryo cloning efficiency. Our findings not only provide new insights into ways to overcome low cloning efficiency, but also add to the understanding of sperm protein function. This article is protected by copyright.

Abstract
Somatic cell nuclear transfer (SCNT) shows great value in the generation of transgenic animals, protection of endangered animals, and stem cell therapy. The combination of SCNT and gene editing has produced a variety of genetically modified animals for life science and medical research. Rabbits have unique advantages as transgenic bioreactors and human disease models; however, the low SCNT efficiency severely impedes the application of this technology. The difficulty in SCNT may be attributable to the abnormal reprogramming of somatic cells in rabbits. This review focuses on the abnormal reprogramming of cloned mammalian embryos and evaluates the progress and prospects of rabbit somatic cell cloning.

Abstract
Objective: To explore the effects of narrative therapy on cognition, emotion and treatment satisfaction of convalescent patients with occupational acute chemical toxic encephalopathy. Methods: From June to July 2019, 60 convalescent patients with occupational chemical poisoning encephalopathy were randomly divided into narrative group and control group, with 30 cases in each group. The control group received routine clinical treatment. On the basis of receiving the original clinical treatment, patients in the narrative group added narrative treatment once a week to explain discomfort in specific life situations through conversation from the perspective of disease and psychology. 30 min each time for 6 weeks. The patients were investigated with Montreal Cognitive Assessment Scale (MoCA scale) every 2 weeks to evaluate the degree of cognitive impairment. The changes of depression, anxiety and treatment satisfaction were investigated before and after intervention. Results: There was no significant difference in MoCA scores between the two groups before intervention (P>0.05) . After 6 weeks of treatment, MoCA scores of narrative group and control group gradually increased with the extension of treatment time, and the increase degree of MoCA score of narrative group was greater than that of control group (P<0.01) . Before intervention, there was no significant difference in depression, anxiety score, prevalence and satisfaction index between narrative group and control group (P>0.05) . After the intervention, the scores and prevalence of depression and anxiety in the narrative group were significantly lower than those in the control group, and the scores of feeling in the process of seeing a doctor and how to obtain their own disease information were significantly higher than those in the control group (P<0.05) . Conclusion: Narrative therapy can improve the cognitive function and emotion of patients with occupational chemical poisoning, and improve the treatment satisfaction of patients.

Abstract
OBJECTIVE To observe the effect of adiponectin on osteogenesis in type 2 diabetic rats. METHODS The 4th-week-old male SD rats were divided into normal control group (n=18) and diabetic model group (n = 42). Type 2 diabetes was induced by high-fat and high-sugar diet and intraperitoneal injection of a low dose of streptozotocin (STZ). The successfully-induced diabetic rats were divided into diabetic group (DM=18) and adiponectin intervention group (APN=18). APN group was injected with APN 10 μg/kg*d. The rats were separately sacrificed at the 4th, 8th and 12th week after the intervention. Bone microstructure and adipose tissue were observed via HE staining. Bone marrow was extracted from one side of the femur, and the supernatant was achieved by centrifugation. After BMD assessed by DXA, the other side of the femur was for further HE staining. Runx-2 expression in the bone marrow cells was detected by RT-PCR. BALP and AOPPs in bone marrow supernatant were assayed by ELISA. AGEs were detected by immunohistochemical staining. RESULTS With the feeding time over, blood glucose, AOPP, and AGEs were increased, and Runx-2 mRNA, BALP, BMD were decreased in diabetic rat group(P<0.05). Oxidative stress (OS) maker (AOPP) was decreased and osteogenesis makers (Runx2 mRNA, BALP) were increased after intervention with exogenous adiponectin (P<0.05). At the 8th and 12th week, the trabecular bone became thinner and broken, and the fat cell number increased in all 3 groups, especially in the DM group. The adiponectin intervention group showed that the trabecular bone structure was moderately restored. CONCLUSIONS OS is obvious in bone micro-environment in diabetic rats. OS may have an inhibitory effect on regulation of osteogenic differentiation factor Runx2, causing down regulation of osteoblast differentiation and bone formation. Adiponectin may improve OS response and protect the bone structure.

Abstract
In mammals, sperm-borne regulators can be transferred to oocytes during fertilization and have different effects on the formation of pronuclei, the first cleavage of zygotes, the development of preimplantation embryos and even the metabolism of individuals after birth. The regulatory role of sperm microRNAs (miRNAs) in the development of bovine preimplantation embryos has not been reported in detail. By constructing and screening miRNA expression libraries, we found that miR-202 was highly enriched in bovine sperm. As a target gene of miR-202, co-injection of SEPT7 siRNA can partially reverse the accelerated first cleavage of bovine embryos caused by miR-202 inhibitor. In addition, both a miR-202 mimic and SEPT7 siRNA delayed the first cleavage of somatic cell nuclear transfer (SCNT) embryos, suggesting that miR-202-SEPT7 mediates the delay of first cleavage of bovine embryos. By further exploring the relationship between miR-202/SEPT7, HDAC6 and acetylated α-tubulin during embryonic development, we investigated how sperm-borne miR-202 regulates the first cleavage process of bovine embryos by SEPT7 and demonstrate the potential of sperm-borne miRNAs to improve the efficiency of SCNT.

Abstract
BACKGROUND The regulator of cullins-1 (ROC1) is an essential subunit in the cullin-RING ligase (CRL) protein complex and has been shown to be critical in bladder cancer cell survival and progression. This study aimed to explore the molecular mechanism of ROC1 action in the malignant progression of bladder cancer. METHODS This study utilized ex vivo, in vitro, and in vivo nude mouse experiments to assess the underlying mechanisms of ROC1 in bladder cancer cells. The expression of the components of the sonic hedgehog (SHH) pathway was determined by western blot analysis. ROC1 expression in human tumors was evaluated by immunohistochemistry. RESULTS ROC1 overexpression promoted the growth of bladder cancer cells, whereas knockdown of ROC1 expression had the opposite effect in bladder cancer cells. Mechanistically, ROC1 was able to target suppressor of fused homolog (SUFU) for ubiquitin-dependent degradation, allowing Gli2 release from the SUFU complex to activate the SHH pathway. Furthermore, knockdown of SUFU expression partially rescued the ROC1 knockdown-suppressed SHH activity as well as cancer cell growth inhibition. In ex vivo experiments, tissue microarray analysis of human bladder cancer specimens revealed a positive association of ROC1 expression with the SHH pathway activity. CONCLUSION This study demonstrated that dysregulation of the ROC1-SUFU-GLI2 axis plays an important role in bladder cancer progression and that targeting ROC1 expression is warranted in further investigations as a novel strategy for the future control of bladder cancer.

Abstract
Accumulated evidence indicates that sperm-borne small RNA plays a crucial role in embryonic development, especially the absence of the sperm-borne small RNA might be a major cause of the abnormal development of cloned embryos. In this study, we found that sperm-borne small RNA can affect abnormal pronuclear-like structures, postpone the timing of first embryo cleavage and enhance developmental competence of bovine somatic cell nuclear transfer (SCNT) embryos. In addition, the supplementation of sperm-borne small RNA can significantly increase live birth rates and decrease the birth weights of cloned offspring. To investigate the underlying mechanisms, the levels of α-tubulin K40 acetylation (Ac α-tubulin K40) and histone H3 lysine 9 trimethylation (H3K9me3) during early embryo development were investigated in SCNT embryos with sperm-borne small RNA supplementation (termed as T-NT), compared to those normal SCNT embryos and embryos obtained from standard IVF. The results showed that sperm-borne small RNA can significantly decrease the H3K9me3 levels at the pronuclear and two-cell stages, while significantly increase Ac α-tubulin K40 levels at anaphase and telophase of bovine SCNT embryos during the first cleavage. Collectively, our study for the first time demonstrates that sperm-borne small RNA plays a crucial role in the developmental competence of SCNT embryos by regulating H3K9me3 and Ac α-tubulin K40. Further studies will be required to determine how sperm small RNA regulate the H3K9me3 and Acα-tubulin K40. Our study suggests that the supplementation of sperm-borne small RNA is a potential application to improve the cloning efficiency.

Abstract
Embryo culture conditions are crucial as they can affect embryo quality and even offspring. Oviductal extracellular vesicles (EVs) long been considered a major factor influencing interactions between the oviduct and embryos, and thus its absence is associated with inferior embryonic development in in vitro culture. Herein, we demonstrated that melatonin is present in oviduct fluids and oviduct fluid-derived EVs. Addition of either EVs (1.87 × 1011 particles/mL) or melatonin (340 ng/mL) led to a significant downregulation of reactive oxygen species (ROS) and 5-methylcytosine (5-mC), as well as an increase in the blastocyst rate of embryos, which was inhibited by the addition of luzindole-a melatonin receptor agonist. A combination of EVs (1.87 × 1010 particles/mL) and melatonin (at 34.3 pg/mL) led to the same results as well as a significant decrease in the apoptosis index and increase in the inner cell mass (ICM)/trophectoderm (TE) index. These results suggest that an EV-melatonin treatment benefits embryonic development. Our findings provide insights into the role of EVs and melatonin during cell communication and provide new evidence of the communication between embryos and maternal oviduct.

Abstract
Somatic cell nuclear transfer (SCNT) has shown a wide application in the generation of transgenic animals, protection of endangered animals, and therapeutic cloning. However, the efficiency of SCNT remains very low due to some poorly characterized key factors. Compared with fertilized embryos, somatic donor cells lack some important components of sperm, such as sperm small noncoding RNA (sncRNA) and proteins. Loss of these factors is considered an important reason for the abnormal development of SCNT embryo. This study focused on recent advances of SCNT and the roles of sperm in development. Sperm-derived factors play an important role in nucleus reprogramming and cytoskeleton remodeling during SCNT embryo development. Hence, considering the role of sperm may provide a new strategy for improving cloning efficiency.

Abstract
The study’s objectives were to examine the effects of electrofusion on rabbit somatic cell nuclear transfer (SCNT) embryos, and to test melatonin as a protective agent against electrofusion damage to SCNT embryos. The levels of reactive oxygen species (ROS), the epigenetic state (H3K9me3), and the content of endoplasmic reticulum (ER) stress-associated transcripts (IRE-1 and CHOP) were measured. Melatonin was added during the preimplantation development period. The total blastocyst cell numbers were counted, and the fragmentation rate and apoptotic index were determined and used to assess embryonic development. Electrofusion increased (1) ROS levels at the 1-, 2-, 4-, and 8-cell stages; (2) H3K9me3 levels at the 2-, 4-, and 8-cell stage; and (3) the expression of IRE-1 and CHOP at the 8-cell, 16-cell, morula, and blastocyst stages. The treatment of SCNT embryos with melatonin significantly reduced the level of ROS and H3K9me3, and the expression levels of IRE-1 and CHOP. This treatment also significantly reduced the fragmentation rate and apoptotic index of blastocysts and increased their total cell number. In conclusion, the electrofusion of rabbit SCNT embryos induced oxidative stress, disturbed the epigenetic state, and caused ER stress, while melatonin reduced this damage. Our findings are of signal importance for improving the efficiency of SCNT and for optimizing the application of electrical stimulation in other biomedical areas.

Abstract
Embryo transfer (ET) is an important procedure for assisted reproduction. However, the relatively lower success rate of ET hampers its application potential. In this study we aimed to elucidate the effects of extracellular vesicles derived from donor oviduct fluid (EDOF) on embryo development after ET. Extracellular vesicles from the oviduct were isolated and purified using ultracentrifugation and identified using transmission electron microscopy, NanoSight, bicinchoninic acid (BCA) protein assay and western blotting. The results revealed that extracellular vesicles were present in donor oviduct fluid in higher concentrations (P<0.05) and contained more proteins (P<0.05) than extracellular vesicles derived from recipient oviduct fluid (EROF). EDOF or EROF were supplemented in an ET medium (ETM) and the results showed that EDOF significantly improved birth rate via resisting apoptosis and promoting differentiation. In conclusion, our study indicated that there are differences in EDOF and EROF and that supplementing EDOF to ETM can improve the efficiency of ET; improved ET efficiency promotes the use of gene editing and benefits assisted reproductive technology and animal welfare.

Abstract
OBJECTIVE To investigate the effects of an inhibitor of NF-κB, PDTC (pyrrolidine dithiocarbamate), on TLR4 (Toll-like receptor 4) expression in the left ventricle of Goldblatt hypertension rats. MATERIALS AND AND METHODS Goldblatt rat model of two-kidney, one-clip (2K1C) hypertension was established in 70 healthy male rats. The rats were randomly divided into sham operation group (S group, n=20), non-drug intervention hypertension group (H group, n=25), and PDTC intervention group (P group, n=25). P group was injected with PDTC. The clip was inserted in the left renal artery of H group and P group (2K1C). Eight weeks after the operation, the rats were sacrificed and the samples of the left ventricle were collected. The concentration of AngII in the left ventricle was assessed by radioimmunoassay. RT-PCR was used to examine the mRNA expression of TLR4 in the left ventricle. Immunohistochemistry was adopted to examine the location of TLR4 and NF-κB in the myocardium. Victoria blue-Ponceau staining of Cardiac collagen was used to evaluate the degree of myocardial fibrosis. RESULTS Eight weeks after the operation, caudal SBP, meridional end-systolic stress, left ventricular mass index, relative wall thickness, cardiac fibrosis degree, and the concentration of AngII in the left ventricle in P group were significantly lower than those in H group (p<0.01). In cardiac myocytes of S group and P group, TLR4 expression was diffused and presumably cytoplasmic. TLR4 mRNA expression in P group was significantly lower than that of H group (p<0.01). CONCLUSIONS PDTC not only inhibited the activation of NF-κB, but decreased TLR4 expression and AngII content, indicating that the inflammatory signals and oxidative stress mediated by TLR4/NF-κB are involved in the occurrence and development of left ventricular remodeling. Intervention with TLR4/NF-κB and anti-inflammatory and anti-oxidative therapy may be a new target to reverse left ventricular remodeling.

Abstract
Relative to alanine and serine amino acid levels, glutamine is highly abundant in follicular fluid, and is an important source of energy required for oocyte maturation and embryo development. Thus, glutamine is an essential component of in vitro embryo culture media. However, glutamine has poor stability and degrades spontaneously in solution to form ammonia and pyrrolidonecarboxylic acid. In the present study, we aimed to explore the effect of substituting l-glutamine with glycine-glutamine, a more stable glutamine, on development of early parthenogenetic embryos and in vitro fertilization (IVF) embryos in bovine. Results revealed that glycine-glutamine can significantly increase cleavage rate (parthenogenetic embryos:87.24% vs. 72.61%, IVF embryos:89.33% vs. 83.79%, P < 0.01), blastocyst number (parthenogenetic embryos:24.98% vs. 18.07%, IVF embryos:33.53% vs. 27.29%, P < 0.01), and blastocyst number (parthenogenetic embryos:96 vs. 76, IVF embryos:114 vs. 109, P < 0.01), reduce blastocyst apoptosis (parthenogenetic embryos:3.72% vs. 6.65%, IVF embryos:2.53% vs.6.23%, P < 0.01), alleviate embryo ammonia toxicity, and reduce the content of reactive oxygen species (ROS) compared with the l-glutamine. In addition, glycine-glutamine can alter epigenetic reprogramming by increasing the expression of HDAC1 (Histone Deacetylase 1) and decreasing the relative expression levels of H3K9 acetylation in early parthenogenetic embryos and IVF embryos. From our present study, we concluded that glycine-glutamine is an effective substitute of glutamine in modified synthetic oviduct fluid with amino acids (mSOFaa).

Abstract
BACKGROUND Although a large number of studies have identified obesity as an independent risk factor for the development of periprosthetic joint infection (PJI), the synergistic impacts of obesity with other factors on PJI remain unknown. Additionally, few studies have specifically explored the risk factors of PJI within a Chinese population. AIMS To investigate the association between obesity and PJI in a Chinese population, and identify synergistic impacts of obesity with other risk factors on the development of PJI. METHODS Three hundred and seven patients at a single institution with a diagnosis of PJI following primary total hip or knee arthroplasty, treated from 2008 to 2015, were identified. Each case was matched with two controls who did not develop PJI after primary total hip or knee arthroplasty in the study period using propensity score matching for several important parameters. Multi-variable logistic regression models were used to estimate the association between body mass index (BMI) and the risk of developing PJI. Interaction and stratified analyses were conducted according to age, sex, type of surgery, smoking status, alcohol use, diabetes, inflammatory arthritis, liver disease and renal disease. FINDINGS The multiple logistic analyses showed that obesity was associated with increased risk of PJI [odds ratio (OR) 2.48; 95% confidence interval (CI) 1.66-3.69]. When analysed as a continuous variable, BMI was also associated with increased risk of PJI (OR per 1 kg/m2 increase in BMI 1.08; 95% CI 1.02-1.14). In the interaction analysis, patients who were obese and smoked had a higher OR of developing PJI than non-smokers who were obese (OR 3.54 vs 1.55, P-value for interaction=0.031). Similarly, the OR was much higher for patients with both obesity and inflammatory arthritis than for patients who were obese with no history of inflammatory arthritis (OR 3.9 vs 1.55, P-value for interaction=0.029). No other significant interactions were found in the association between obesity and PJI. CONCLUSION Obesity is an independent risk factor for the development of PJI in the Chinese Han population. Surgeons should be aware that obese patients who smoke or have inflammatory arthritis are at additional increased risk of PJI.

Abstract
Serum starvation is a routine protocol for synchronizing nuclear donor cells to G0/G1 phase during somatic cell nuclear transfer (SCNT). However, abrupt serum deprivation can cause serious stress to the cells cultured in vitro, which might result in endoplasmic reticulum (ER) stress, chromosome damage, and finally reduce the success rate of SCNT. In the present study, the effects of tauroursodeoxycholic acid (TUDCA), an effective ER stress-relieving drug, on the nuclear donor cells under serum deprivation condition as well as following SCNT procedures were first assessed in the bovine. The results showed that TUDCA significantly reduced ER stress and cell apoptosis in those nuclear donor cells. Moreover, it significantly decreased the expression of Hdac1 and Dnmt1, and increased the level of H3K9 acetylation in nuclear donor cells compared with control group. SCNT reconstructed embryos cloned from TUDCA-treated donor cells showed significantly higher fusion, cleavage, blastocyst formation rate, total cell number in day 7 blastocysts, and lower apoptotic index than that from control group. In addition, the expression of Hdac1, Dnmt1 and Bax was significantly lower in blastocysts derived from TUDCA-treated donor cells than that from control group. In conclusion, TUDCA significantly reduced the ER stress of nuclear donor cells under serum starvation condition, and significantly improved the developmental competence of following SCNT reconstructed embryos when these TUDCA-treated cells were used as the nuclear donors.

Abstract
Interferon-tau (IFNT), a type I interferon, is an antiluteolytic factor secreted by trophoderm during pregnancy. IFNT transmitted signals or stimulated the expression of some factors to build maternal recognition and keep pregnancy by binding its receptors, IFNT receptor 1(IFNAR1) and IFNT receptor 2 (IFNAR2). Up to now, the expression model and roles of IFNAR1 and IFNAR2 in placenta have not been investigated in cattle. In this study, the localization and expression of IFNAR1 and IFNAR2 in the cattle placenta at days 18-50 of pregnancy were detected by histological examination, immunofluorescence staining and real-time qPCR. The results showed that IFNAR1 mainly distributed in chorioallantoic membrane, endometrial epithelium, cotyledon and caruncle during the early pregnancy of cattle with change in time- and position-dependent. IFNAR1 and IFNAR2 mRNA expression were mainly detected in chorioallantoic membrane and cotyledon, and markedly increased along with pregnancy process. Moreover, the mRNA expression level of IFNAR1 in chorioallantoic membrane and cotyledon was higher than that of IFNAR2. IFNAR mRNA was also expressed in caruncle tissues, which experienced a tendency of decrease from days 21 to 36, followed by increase after days 36. These results provide morphological basis and quantitative data for investigating the roles of IFNAR1 and IFNAR2 on development of cattle placenta and pregnancy maintenance.

Abstract
Somatic cell nuclear transfer (SCNT)-mediated reprogramming is a rapid, efficient, and sophisticated process that reprograms differentiated somatic cells to a pluripotent state. However, many factors in this elaborate reprogramming process remain largely unknown. Here, we report that the microRNA (miR) miR-125b is an important component of SCNT-mediated reprogramming. Luciferase reporter assay, quantitative PCR, and Western blotting demonstrated that miR-125b directly binds the 3'-untranslated region of SUV39H1, encoding the histone-lysine N-methyltransferase SUV39H1, to down-regulate histone H3 lysine-9 tri-methylation (H3K9me3) in SCNT embryos. Furthermore, the miR-125b/SUV39H1 interaction induced loss of SUV39H1-mediated H3K9me3, caused heterochromatin relaxation, and promoted the development of SCNT embryos. Transcriptome analyses of SCNT blastomeres indicated that HNF1 homeobox B (HNF1B), a gene encoding a transcription factor downstream of and controlled by the miR-125b/SUV39H1 axis, is important for conferring developmental competence on preimplantation embryos. We conclude that miR-125b promotes SCNT-mediated nuclear reprogramming by targeting SUV39H1 to decrease the deposition of repressive H3K9me3 modifications.

Abstract
The developmental competence of in vitro cultured (IVC) embryos is markedly lower than that of their in vivo counterparts, suggesting the need for optimization of IVC protocols. Embryo culture medium is routinely replaced three days after initial culture in bovine, however, whether this protocol is superior to continuous nonrenewal culture method under current conditions remains unclear. Using bovine somatic cell nuclear transfer (SCNT) embryos as the model, our results showed that compared with routine renewal treatment, nonrenewal culture system significantly improved blastocyst formation, blastocyst quality (increased total cell number, decreased stress and apoptosis, enhanced Oct-4 expression and ratio of ICM/TE), as well as following development to term. Existence and function of SCNT embryo-derived exosomes were then investigated to reveal the cause of impaired development induced by culture medium replacement. Exosomes were successfully isolated through differential centrifugation and identified by both electron microscopy and immunostaining against exosomal membrane marker CD9. Supplementation of extracted exosomes into freshly renewed medium significantly rescued not only blastocyst formation and quality (in vitro development), but also following growth to term (in vivo development). Notably, ratio of ICM/TE and calving rate were enhanced to a similar level as that in nonrenewal group. In conclusion, our results for the first time indicate that 1: bovine SCNT embryos can secrete exosomes into chemically defined culture medium during IVC; 2: secreted exosomes are essential for SCNT blastocyst formation, blastocyst quality, and following development to term; 3: removal of exosomes induced by culture medium replacement impairs SCNT embryo development, which can be avoided by nonrenewal culture procedure or markedly recovered by exosome supplementation.

Abstract
Nuclei from less differentiated stem cells yield high cloning efficiency. However, pluripotent stem cells are rather difficult to obtain from bovines. Skin-derived precursor (SKPs) cells exhibit a certain degree of pluripotency, which has been shown to enhance the efficiency of nuclear transfer (NT) in pigs. In this study, bovine SKPs were isolated and characterized. Results showed that bovine SKPs expressed nestin, fibronectin, vimentin, pluripotency-related genes, and characteristic neural crest markers, such as NGFR, PAX3, SOX9, SNAI2, and OCT4. Bovine SKPs and fibroblasts were used as NT donor cells to examine and compare the preimplantation developmental potential of reconstructed embryos after somatic cell nuclear transfer (SCNT). Bovine SKP-cloned embryos displayed higher developmental competence in terms of blastocyst formation rate and total cell number in blastocysts compared with the bovine embryonic fibroblast-cloned embryos. This study revealed that bovine SKPs may be considered excellent candidate nuclear donors for SCNT and may provide a promising platform for transgenic cattle generation.

Abstract
A green and facile approach to produce graphene using an environmentally friendly reagent, namely proanthocyanidin (PC) as a reducing agent was developed. The obtained graphene (PC-rGO) was characterized using Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis and X-ray photoelectron spectroscopy, confirming the effective reduction of GO. With the incorporation of PC-rGO into natural rubber (NR) latex, NR/PC-rGO composites were then prepared by an ultrasonically assisted latex mixing and the co-coagulation. The results show that PC-rGO presents a good dispersion and exfoliation in the NR matrix, contributing to an increase in the mechanical performance. Compared with neat NR, the tensile strength, modulus at 300%, and tear strength for NR composites containing 0.9 phr PC-rGO were increased by 50.2%, 154.9% and 65.2%, respectively. With increasing PC-rGO loading, cross-link density and storage modulus of NR composites increase because of the formation of cross-link points and physical interaction between PC-rGO and the matrix.

Abstract
BACKGROUND In addition to lipolytic function, ANP plays regulatory roles in the production of various adipokines including adiponectin, leptin, and interleukins. However, the adipose effects of vasonatrin peptide (VNP), a new manmade natriuretic peptide, are largely unknown. AIM The aim of the present study was to identify the roles of VNP on adipokines production, as well as signaling pathways involved. MATERIAL, SUBJECTS, AND METHODS: 3T3-L1 cells were differentiated into adipocytes and exposed to various concentrations of VNP. Quantitative PCR and immunoassays were performed to determine the mRNA and protein levels of adiponectin and interleukin-6 (IL-6), respectively. The involved signaling pathway was identified by radioimmunoassay to detect the levels of intracellular cyclic GMP (cGMP), mimicking experiments using 8-brcGMP (a membrane-permeable cGMP analog). Also, blocking experiments were performed using HS-142-1, an antagonist of particulate guanylyl cyclase-coupled natriuretic peptide receptor (NPR), or KT-5823, the cGMP-dependent protein kinase (PKG) inhibitor. RESULTS VNP markedly enhanced adiponectin mRNA expression, as well as protein secretion, however, suppressed IL-6 production in mature adipocytes. In addition, VNP significantly increased the intracellular levels of cGMP. The effects of VNP were mimicked by 8-br-cGMP, whereas inhibited by HS-142-1, or KT-5823. CONCLUSIONS Taken together, VNP regulates adiponectin and IL-6 production in adipocytes via guanylyl cyclase-coupled NPR/cGMP/PKG pathway.

Abstract
8538 Background: The prognosis of patients with MM is best captured by gene expression profiling (GEP) analysis of CD138-purified plasma cells (PC), distinguishing a high-risk group of 15% with dismal survival using a 70-gene baseline risk model (BLR). Translational research in TT3 was designed to investigate whether short-term BOR-induced GEP alterations could advance our understanding of BOR's novel mechanism of action. Methods: PG studies were performed as part of two TT3 trials (TT3a, n=303; TT3b, n=177), obtaining PC prior to and 48hr after a BOR test-dose (1.0mg/m2), which was accomplished in 142 patients in TT3a (training set) and 127 in TT3b (test set). Among 1051 genes significantly altered post-BOR in TT3a, 80 were identified as being significantly associated with EFS. A continuous risk score was calculated and an optimal cut-point for EFS separation determined. The independent prognostic power of the binary risk score was tested in TT3b. Multivariate analyses (MV) were employed to determine post-BOR risk (PBR) in relationship to standard prognostic variables and BLR. Results: The discriminatory power in TT3a (3-yr OS: 95% v 45%, p<0.0001; 3-yr EFS: 90% v 35%, p<0.0001) was confirmed in TT3b (18-mo OS: 100% v 65%, p=0.0004; 18-mo EFS: 95% v 45%, p<0.0001). Evaluating PBR in the context of BLR, 12/26 in TT3a and 7/21 in TT3b deemed as having low BLR had high PBR; conversely, 8/126 in TT3a and 14/106 in TT3b deemed as having high BLR had low PBR. In the context of our 8 molecular subgroup model, high PBR was over-represented in the Proliferation (PR) subgroup (7/15 in TT3a, 8/18 in TT3b) and absent in the Low Bone disease (LB) group (0/28). On MV, PBR was an independent adverse variable for both OS and EFS in TT3a (OS: HR=3.17, p=0.006, R2=55%; EFS: HR=4.40, p<0.001, R2=48%) and in TT3b (OS: HR=13.00, p=0.002, R2=48%; EFS: HR=15.57, p<0.001, R2=55%). Proteasome genes ranked first among those differentially up-regulated by BOR. Conclusions: PG identified a powerful 80-gene PBR model with unprecedented prognosis-discriminating power, dispelling BLR from MV analysis by altering BLR designation mainly from low to high risk. High PBR (18%) could be traced to up-regulation of proteasome genes, the target of BOR. [Table: see text]

Abstract
8522 Background: Clinical outcome in patients (pts) with asymptomatic plasma-proliferative disorders, monoclonal gammopathy of undetermined significance (MGUS) and asymptomatic myeloma (AMM), is highly variable. There is a need to identify specific tumor or host related features that predict the risk of disease progression. In prior studies, we have shown that patients with MGUS commonly mount a T cell immune response against SOX2, an antigen critical for pluripotency of ES cells. Methods: Patients with MGUS/AMM were enrolled in a prospective observational clinical protocol (SWOG S0120). All patients underwent detailed staging evaluation at registration and were observed without therapy. The presence of T cell immunity to SOX2 in freshly isolated blood / marrow mononuclear cells was analyzed using an overlapping peptide library at study entry. Results: Anti-SOX2 T cell responses were detected in 39/109 (36%) pts tested. Progression to symptomatic MM was observed in only 2 of 39 patients with anti-SOX2 immunity compared to 17 of 59 pts lacking these responses, resulting in 2-yr progression-free survival 96 v 63% (p=0.003). Responses to viral antigens and polyclonal mitogens as controls were preserved in patients lacking SOX2 immunity indicating that the absence of immunity to SOX2 was not due to global immune-suppression. Immunity to SOX2 correlated with features of lower risk including serum-M component < 1.5 g/dL (p=0.008), marrow plasmacytosis < 10% (p<0.001) and normal serum free light chain ratio (p=0.01). Conclusions: These data demonstrate in the context of a prospective trial that T cell immunity to stem cell genes strongly correlates with a reduced risk of progression to clinical myeloma. These data point to SOX2 as a potential target for the prevention of disease progression in MGUS/AMM. No significant financial relationships to disclose.

Abstract
8520 Background: Total Therapy 3 (TT3) incorporated bortezomib (BOR) to co-target ME that plays an important role in MM progression and drug resistance. Consenting patients received a BOR test dose of 1mg/m2 to determine whether ME alterations induced 48hr post-BOR could clarify the drug's in-vivo mechanism of action in the context of achieving MM control. Methods: Bone marrow biopsies were obtained at baseline (BL) prior to and 48hr after BOR (PB) in 70 of 303 patients receiving TT3a (training set) and in 45 of 177 patients enrolled in TT3b (test set). Among 608 ME genes distinguishing BL and PB training samples, 58 were identified as being significantly linked to short event-free survival (EFS). A summary score was computed based on the percent change of these 58 genes (PB-ME-S). Additionally, 20 ME genes were selected whose BL expression predicted OS, arriving at a BL score (BL-ME-S). Results: Applying the PB-ME-S score, 3-yr OS and EFS estimates were 96% and 96% among the 49 patients with low PB-ME-S and 50% and 38% in the 21 with high PB-ME-S (both p<0.0001). Follow-up is too short to validate the PB-ME-S model in the test set of 45 patients in TT3b. The BL-ME-S distinguished OS and EFS in the training set of 70 patients, with 3-yr OS and EFS estimates of 92% and 91% among the 50 patients with low and 54% and 45% in the 20 patients with high BL-ME-S (both P<0.0001). These data were validated in 113 patients with only BL-ME data: 3-yr OS and EFS were 90% and 85% among the 89 patients with low as opposed to 70% and 55% among the 14 patients with high BL-ME-S (p=0.001, p=0.002). TT3 survival was independently significantly affected by PB-ME-S (OS: HR=12.74, p=0.002; EFS: HR=14.32, p<0.001) and BL-ME-S (EFS: HR=3.10, p=0.045), whereas the univariately significant role of BL-PC-S for both endpoints could not be confirmed on multivariate analysis. Conclusions: To our knowledge, this is the first report documenting a validated prognostic role of ME for cancer survival. Key genes shared by both PB-ME-S and BL-ME-S models are involved in endothelial and mesenchymal stem-cell signaling, the details of which will be reported at the meeting. [Table: see text]

Abstract
Tissue damage and inflammation promote bone marrow stem cells (BMSCs) to differentiate into a variety of cell types in residing tissues. BMSCs can stably maintain their plasticity and are an ideal cell population for delivery of therapeutic genes to non-hematopoietic tissues. Using lacZ as a reporter gene, we demonstrated that the lung-specific human surfactant protein B (hSP-B) 1.5-kb promoter is able to deliver the lacZ gene into the lung of lysosomal acid lipase (LAL) gene-knockout (lal-/-) mice by beta-galactosidase staining, flow cytometry and double immunofluorescence staining. Around 10-18% alveolar type II epithelial cells (AT II cells) exhibited positive lacZ gene expression after 8 weeks of BMSC injection in recipient lal-/- mice. The wild-type mice exhibited no expression after the same treatment. BMSCs from hSP-B 1.5-kb lacZ transgenic mice entered and repopulated in lal-/- bone marrow. The study supports a concept that pulmonary inflammation caused by LAL deficiency can trigger BMSC residing in lal-/- bone marrow, migrating into the lung and converting into residential AT II cells. The hSP-B 1.5 kb promoter is an ideal tool to deliver therapeutic genes into AT II cells through BMSCs to cure pulmonary inflammation-triggered diseases.

Abstract
OBJECTIVE Test the hypothesis that soy isoflavone supplementation preserves bone mineral density (BMD) in men and women. METHODS We conducted a controlled, parallel-arm, double-blinded trial with 145 participants, 50-80 years, with random assignment to soy beverage daily for 12 months. Active treatment (+ISO) received soy protein containing 83 mg isoflavones (45.6 mg genistein, 31.7 mg daidzein), aglycone units; the comparison group (-ISO) received soy protein containing 3mg isoflavones. We measured BMD using dual-energy X-ray absorptiometry at the total hip and posterior-anterior spine (L1-L4) at baseline in 22 women and 123 men, and at 12 months in 13 women and 98 men. We used linear mixed models to test for an isoflavone effect on percentage BMD change from baseline in spine and hip. RESULTS Among all participants, mean percent change in spine BMD (+/-S.E.) was 0.16+/-0.44 in -ISO (P=0.10) at 12 months. Treatment effects on spine BMD were significantly greater in women than men (P=0.01). At 12 months, in women, mean percent change was 0.58+/-0.70 in +ISO and -1.84+/-0.86 in -ISO (P=0.05); among men it was 1.32+/-0.53 in +ISO and 0.31+/-0.48 in -ISO (P=0.16). By comparison, percent change in hip BMD was similar in the treatment groups, and was not different between men and women. Mean percent change in hip BMD from baseline to 12 months was 0.54+/-0.38 in +ISO and -0.13+/-0.36 in -ISO (P=0.20) among all participants. CONCLUSIONS Soy protein containing isoflavones showed a modest benefit in preserving spine, but not hip BMD in older women.
