Abstract
The cultivated peanut, A. hypogaea L., is an important oil and food crop globally.High-density genetic linkage mapping is a valuable and effective method for exploring complex quantitative traits. In this context, a recombinant inbred line (RIL) of 146 lines was developed by crossing Huayu28 and P76. We developed 433,679 high-quality SLAFs, of which 29,075 were polymorphic. 4,817 SLAFs were encoded and grouped into different segregation patterns. A high-resolution genetic map containing 2,334 markers (68 SSRs and 2,266 SNPs) on 20 linkage groups (LGs) spanning 2586.37 cM was constructed for peanut. The average distance between adjacent markers was 2.25 cM. Based on phenotyping in seven environments, QTLs for oleic acid (C18:1), linoleic acid (C18:2) and the ratio of oleic acid to linoleic acid (O/L) were identified and positioned on linkage groups A03, A04, A09, B09 and B10. Marker2575339 and Marker2379598 in B09 were associated with C18:1, C18:2 and O/L in seven environments, Marker4391589 and Marker4463600 in A09 were associated with C18:1, C18:2 and O/L in six environments. This map exhibits high resolution and accuracy, which will facilitate QTL discovery for essential agronomic traits in peanut.

Abstract
OBJECTIVE Desmoplasia and hypovascularity are thought to impede drug delivery in pancreatic ductal adenocarcinoma (PDAC). However, stromal depletion approaches have failed to show clinical responses in patients. Here, we aimed to revisit the role of the tumour microenvironment as a physical barrier for gemcitabine delivery. DESIGN Gemcitabine metabolites were analysed in LSL-KrasG12D/+ ; LSL-Trp53R172H/+ ; Pdx-1-Cre (KPC) murine tumours and matched liver metastases, primary tumour cell lines, cancer-associated fibroblasts (CAFs) and pancreatic stellate cells (PSCs) by liquid chromatography-mass spectrometry/mass spectrometry. Functional and preclinical experiments, as well as expression analysis of stromal markers and gemcitabine metabolism pathways were performed in murine and human specimen to investigate the preclinical implications and the mechanism of gemcitabine accumulation. RESULTS Gemcitabine accumulation was significantly enhanced in fibroblast-rich tumours compared with liver metastases and normal liver. In vitro, significantly increased concentrations of activated 2',2'-difluorodeoxycytidine-5'-triphosphate (dFdCTP) and greatly reduced amounts of the inactive gemcitabine metabolite 2',2'-difluorodeoxyuridine were detected in PSCs and CAFs. Mechanistically, key metabolic enzymes involved in gemcitabine inactivation such as hydrolytic cytosolic 5'-nucleotidases (Nt5c1A, Nt5c3) were expressed at low levels in CAFs in vitro and in vivo, and recombinant expression of Nt5c1A resulted in decreased intracellular dFdCTP concentrations in vitro. Moreover, gemcitabine treatment in KPC mice reduced the number of liver metastases by >50%. CONCLUSIONS Our findings suggest that fibroblast drug scavenging may contribute to the clinical failure of gemcitabine in desmoplastic PDAC. Metabolic targeting of CAFs may thus be a promising strategy to enhance the antiproliferative effects of gemcitabine.

Abstract
Objective: To analyze the clinicopathological characteristics of renal lesions in type 2 diabetic patients and to differentiate diabetic nephropathy (DN) from non-diabetic renal diseases(NDRD). Methods: Type 2 diabetic patients who received renal biopsy in Ruijin Hospital from January 2011 to December 2015 were recruited in this study. Clinical history, laboratory results and pathological data were retrospectively collected. According to the pathological findings, the patients were divided into 3 groups: DN, NDRD, DN+NDRD. Logistic model was applied to explore the independent clinical predictive factors in differentiating DN from NDRD. Results: A total of 207 type 2 diabetic patients received renal biopsy, accounting for 6.82% of all biopsy population. Fifty-one patients were diagnosed with DN, 142 with NDRD and 14 with both DN and NDRD. In NDRD, membranous nephropathy(MN)(34.5%) was the most common finding, followed by IgA nephropathy(19.7%).By contrast, NDRD patients manifested a shorter diabetic course, a higher baseline hemoglobin level, a lower baseline serum creatinine, a higher prevalence of hematuria, a lower prevalence of hypertension and diabetic retinopathy, a better control of blood glucose, better compliance of monitoring blood glucose and less family history of diabetes. In multivariate logistic model, diabetic family history(OR=4.68, P=0.04) and long history of diabetes(OR=1.01, P=0.02) were risk factors of DN. Conclusion: There is a high prevalence of NDRD in diabetic patients with renal lesions. Family history of diabetes and duration of diabetes are independent predictors of DN.

Abstract
OBJECTIVE Hypoxia has been shown to inhibit reactive oxygen species (ROS) production in nucleus pulposus (NP) cells. The TP53-induced glycolysis and apoptosis regulator (TIGAR) has been reported to suppress oxidative stress. We sought to explore the role of TIGAR in the effect of hypoxia on ROS production and apoptosis. METHODS An intervertebral disc degeneration (IDD) model of Sprague-Dawley (SD) rat caudal spine was established by puncturing the Co6-7 disc. TIGAR expression was detected by immunohistochemistry and western blotting in human and SD rat NP tissues of degenerated discs. Rat primary NP cells treated with hypoxia and cobalt chloride (CoCl2) were analyzed by western blotting for TIGAR expression. After TIGAR silence with TIGAR siRNA transfection, apoptosis percentage, mitochondrial and total intracellular ROS levels were measured. H2O2 was used to further check the effects of TIGAR on oxidative stress. Finally, NADPH/NADP+ and GSH/GSSH ratio were examined after TIGAR silencing under hypoxic conditions and after H2O2 treatment. RESULTS A degree-dependent increase in TIGAR expression was observed in human and rat degenerated NP tissues. Hypoxia and hypoxia-inducer CoCl2 enhanced TIGAR and P53 expressions in rat NP cells. TIGAR silence reversed the inhibitory effects of hypoxia on intracellular and mitochondrial ROS production, as well as apoptosis percentage. However, TIGAR silence aggravated H2O2-induced ROS production. In addition, TIGAR increased NADPH/NADP+ and GSH/GSSH ratio in NP cells. CONCLUSIONS These results suggested that TIGAR appears to mediate the protective role of hypoxia on ROS production and apoptosis percentage by enhancing NADPH/NADP+ and GSH/GSSH ratio.

Abstract
OBJECTIVE To investigate serum IgG4 levels in different diseases and the changes of serum IgG4 levels in post treatment of IgG4 related disease. METHODS Clinical data of 620 patients who received investigation of serum IgG4 in Peking University People's Hospital from January 1, 2015 to March 31, 2016 were collected retrospectively. According to the difference of the diseases, they were divided into common group of diseases, autoimmune diseases and IgG4 related diseases; pancreatic disease patients were divided into autoimmune pancreatitis and pancreatic cancer group; According to different treatment stages of the disease, the patients with IgG4 related diseases were divided into pretreatment group and post treatment group. And the expressions of the patients'serum IgG4 levels in different groups were analyzed. RESULTS The median serum IgG4 level in the group of the patients with common diseases was 0.480(0.005, 50.400) g/L, in the group of autoimmune disease was 0.406 (0.003, 18.700) g/L , in the group of IgG4 related diseases was 5.200(0.046, 46.000)g/L, which was signi-ficantly higher in the group of IgG4 related diseases than the other two groups, and there was obvious statistical significance in serum IgG4 levels between the group of IgG4 related diseases and the other two groups (P<0.01); There was no obvious difference in serum IgG4 levels between the common disease group and the autoimmune disease group, and there was no obvious statistical difference in serum IgG4 levels between the two groups (P>0.05). In the patients with IgG4 related diseases, the median serum IgG4 level in the group of pretreatment patients was 6.540 (1.330, 34.100) g/L, and 3.735 (0.063, 46.000) g/L in the post treatment patients. Serum IgG4 levels decreased in post treatment group, signi-ficantly lower than in pretreatment, there was obvious statistical difference in serum IgG4 levels between the two groups (P<0.01). The median serum IgG4 level in the group of patients with autoimmune pancreatitis was 3.735 (0.063, 46.000) g/L ,and 0.438 (0.056, 1.130) g/L in the group of patients with pancreatic cancer,which was significantly higher in the group of patients with autoimmune pancreatitis than the others, and there was obvious statistical difference in serum IgG4 levels between the two groups (P<0.01). CONCLUSION Serum IgG4 levels in patients with different diseases were different, and were significantly higher in patients with autoimmune pancreatitis and IgG4 related diseases, so serum IgG4 levels can provide the basis for the differential diagnosis of different diseases; Serum IgG4 levels in patients with IgG4 related diseases decrease significantly after treatment, so it can be used as an important index to evaluate the curative effect of IgG4 related diseases.

Abstract
Objective: To explore the clinical and electrophysiological features and prognosis of distal myasthenia gravis (MG). Methods: Data of MG patients in Beijing Tiantan Hospital from October 2016 to March 2017 were reviewed, including thorough neurological examinations, nerve conduction studies, repetitive nerve stimulations (RNS) and needle electromyographies. Distal MG patients were included and were analyzed as to their clinical and electrophysiological features and response to treatments. Results: Four patients (7.7%) could be classified as distal type among 52 definitely diagnosed MG patients. They had initial symptoms at age 36 to 64 and developed distal limb muscle weakness in the first month to 6 years after the onset of this disease. Hand muscles were preferentially involved in a non-uniform way. And one patient also had leg weakness on his tibialis anterior muscles. RNS showed a more significant decrement at slow rates in distal muscles, compared with proximal muscles. The baseline compound muscle action potentials (CMAP) of the distal affected muscles presented with slightly decreased or fluctuating amplitudes. Their weakness of ocular, bulbar, proximal and distal limb muscles improved generally after administration of acetylcholinesterase inhibitors or steroids plus acetylcholinesterase inhibitors. Electrophysiological reexaminations revealed increased baseline CMAPs, reduced decrement on RNS, and relief of myogenic changes on needle electromyography. Conclusions: Relatively prominent distal limb muscle weakness can be found in a minority of MG patients. Besides profound decrement on slow rate RNS, the involved distal muscles may have a characteristic decreased baseline CMAP, sometimes with a diurnal fluctuation. Distal MG responds well to regular treatments. Its short-term prognosis seems similar to that of common MG with proximal predominance.

Abstract
Numerous studies have been conducted to investigate genetic diversity, origins and domestication of donkey using autosomal microsatellites and the mitochondrial genome, whereas the male-specific region of the Y chromosome of modern donkeys is largely uncharacterized. In the current study, 14 published equine Y chromosome-specific microsatellites (Y-STR) were investigated in 395 male donkey samples from China, Egypt, Spain and Peru using fluorescent labeled microsatellite markers. The results showed that seven Y-STRs-EcaYP9, EcaYM2, EcaYE2, EcaYE3, EcaYNO1, EcaYNO2 and EcaYNO4-were male specific and polymorphic, showing two to eight alleles in the donkeys studied. A total of 21 haplotypes corresponding to three haplogroups were identified, indicating three independent patrilines in domestic donkey. These markers are useful for the study the Y-chromosome diversity and population genetics of donkeys in Africa, Europe, South America and China.

Abstract
PURPOSE To test if active breath control during cone-beam computed tomography (CBCT) could improve planning target volume during accelerated partial breast radiotherapy for breast cancer. METHODS Patients who were more than 40 years old, underwent breast-conserving dissection and planned for accelerated partial breast irradiation, and with postoperative staging limited to T1-2 N0 M0, or postoperative staging T2 lesion no larger than 3cm with a negative surgical margin greater than 2mm were enrolled. Patients with lobular carcinoma or extensive ductal carcinoma in situ were excluded. CBCT images were obtained pre-correction, post-correction and post-treatment. Set-up errors were recorded at left-right, anterior-posterior and superior-inferior directions. The differences between these CBCT images, as well as calculated radiation doses, were compared between patients with active breath control or free breathing. RESULTS Forty patients were enrolled, among them 25 had active breath control. A total of 836 CBCT images were obtained for analysis. CBCT significantly reduced planning target volume. However, active breath control did not show significant benefit in decreasing planning target volume margin and the doses of organ-at-risk when compared to free breathing. CONCLUSION CBCT, but not active breath control, could reduce planning target volume during accelerated partial breast irradiation.

Abstract
Polyphenols in Eucalyptus leaves (PE) were value resources due to various pharmacological activities, but data on the effect on laying hens are very scare. This study was conducted to determine the effect of PE on the laying performance, egg traits, meat quality, antioxidant status and liver tissues of laying hens. One hundred and twenty 256-day-old Yueqinhuang laying hens were randomly assigned to four treatment groups (different levels of PE at 0, 0.5, 0.8 and 1.2 g/kg diet) for 63 days with 15 replicates per group. Addition of 0.8 g/kg PE not only improved the egg trait by increasing the eggshell thickness and decreasing MDA production and cholesterol content in the egg yolk, but also significantly enhanced meat quality of hens, as suggested by the increase pH45 min (p < .01) and a* value, and decrease drip loss rate (p < .01). Meanwhile, under acute ethanol-induced oxidative damage condition, supplementation of 0.8 g/kg PE enhanced the serum antioxidant status by increasing enzymatic activities (GSH-PX, T-SOD, T-AOC), inhibited oxidative damage and provided protective effect to liver tissue. In conclusion, addition of 0.8 g/kg PE not only improved the egg traits and meat quality without obvious adverse effects, but also increased the serum antioxidant status of the hens and protected their liver tissue from ethanol-induced oxidative damage. This study indicated that PE could be utilized as an effective feed additive for laying hens to improve health performance and egg traits.

Abstract
UNLABELLED Radiographs and medical record of all adult patients with a mallet fracture in three hospitals between 2004 and 2014 were reviewed. International Classification of Diseases, Ninth Revision (ICD-9) codes and text search in radiographic reports were used to identify all acute patients with potential mallet fractures in our institutional database. Manually checking, 392 true mallet fractures were identified among them, 78 had subluxation at the time of diagnosis and 19 had subluxation at a later time point during treatment. Fragment size, fragment displacement, and interval between injury and treatment were associated with initial and late subluxation. Subluxation was not observed when the fracture size was less than 39% of the total articular surface. For each 1% increase in total articular surface involvement in fractures with more than 39% involvement, the risk of subluxation increased by 4% and for each 1% of displacement, the risk of subluxation increased by 4%.

Abstract
UNLABELLED We evaluated three risk assessment tools, including bone mineral density (BMD) measurement by dual energy X-ray absorptiometry (DXA), osteoporosis self-assessment tool for Asians (OSTA), and fracture risk assessment tool (FRAX), for the prediction of fracture status among Chinese patients undergoing hemodialysis. All of the three assessment tools have a reasonable capability in discriminating fractures. INTRODUCTION Fractures are common in hemodialysis patients however insufficiently assessed. Our study aimed to assess the ability of three widely used tools [BMD, OSTA, and FRAX] to discriminate fracture status in patients with renal failure undergoing hemodialysis. METHODS We enrolled 136 hemodialysis patients in a tertiary teaching hospital setting. BMD was measured using DXA at the lumbar spine and the hip region. OSTA was calculated from weight and age. FRAX score was calculated based upon online availability. Discriminative abilities of BMD, OSTA, and FRAX in fracture status were analyzed by receiver operator characteristic (ROC) curves. RESULTS There were total 16 fractures (11.76 %) identified in 136 hemodialysis patients. BMD at any site (lumbar spine L1-L4, femoral neck, and total hip) was independently associated with fracture. Areas under the curves (AUC) of BMD (lumbar spine L1-L4, femoral neck, total hip), OSTA, FRAX1 (non-BMD model), and FRAX2 (BMD model) were 0.669 (95 % CI 0.583, 0.747), 0.708 ( 95 % CI 0.624, 0.783), 0.736 (95 % CI 0.654, 0.808), 0.686 (95 % CI 0.601, 0.763), 0.715 (95 % CI 0.631, 0.789), and 0.697 (95 % CI 0.613, 0.773), respectively. The differences of their performance were not significant. CONCLUSIONS All of the three risk assessment tools had the ability to discriminate fracture status among hemodialysis patients; FRAX BMD model did not improve the discriminative ability of BMD or FRAX non-BMD model alone.

Abstract
Although phosphoenolpyruvate carboxylases (PEPCs) are reported to be involved in fatty acid accumulation, nitrogen assimilation, and salt and drought stresses, knowledge regarding PEPC gene functions is still limited, particularly in peanuts (Arachis hypogaea L.). In this study, the antisense expression of the peanut PEPC isoform 1 (AhPEPC1) gene increased the lipid content by 5.7%–10.3%. This indicated that AhPEPC1 might be related to plant lipid accumulation. The transgenic plants underwent more root elongation than the wild-type under salinity stress. Additionally, the specific down regulation of the AhPEPC1 gene improved the salt tolerance in peanuts. This is the first report on the role of PEPC in lipid accumulation and salt tolerance in peanuts.

Abstract
We have designed and fabricated a structured streak camera photocathode to provide enhanced efficiency for high energy X-rays (1-12 keV). This gold coated photocathode was tested in a streak camera and compared side by side against a conventional flat thin film photocathode. Results show that the measured electron yield enhancement at energies ranging from 1 to 10 keV scales well with predictions, and that the total enhancement can be more than 3×. The spatial resolution of the streak camera does not show degradation in the structured region. We predict that the temporal resolution of the detector will also not be affected as it is currently dominated by the slit width. This demonstration with Au motivates exploration of comparable enhancements with CsI and may revolutionize X-ray streak camera photocathode design.

Abstract
UNLABELLED Kirschner wires are widely used for skeletal fixation of unstable fractures, but the pin tracks create a potential pathway through the skin and into the bone for bacteria to cause an infection. We tested the null hypothesis that there are no demographic, patient-related, injury, or treatment variables independently associated with the occurrence of pin site infection after percutaneous fixation of hand and wrist fractures using Kirschner wires. A retrospective review of 1213 patients with one or more fractures of the hand and wrist treated with percutaneous Kirschner wire fixation identified 85 patients (7%) who had additional treatment with oral antibiotics, early pin removal, or reoperation related to a pin site infection. We found no factors were independently associated with higher or lower risks of pin site infection in multivariable logistic regression analysis. Pin site infections - most benign - occur in a notable number of patients and we could not identify any modifiable risk factors. LEVEL OF EVIDENCE III.

Abstract
OBJECTIVE In this study, we compared the impact of two main strategies of intervention against multivessel coronary disease (MVD), complete revascularization (CR) and incomplete revascularization (IR), on patients' quality of life. PATIENTS AND METHODS 210 patients with multivessel disease were selected for this study. The diagnosis was confirmed by coronary angiography, and patients were divided in two different groups according to the type of revascularization method they received: (1) the complete revascularization (CR) group and (2) the incomplete revascularization (IR) group. Patients were asked to fill out SF-36 life quality questionnaire in three-time points: (1) before the operation; (2) one month after the operation; and (3) one year after the operation. RESULTS Baseline conditions showed no significant intergroup differences. Scores obtained from different sections in the questionnaire were compared between two groups and results revealed that scores in every section were significantly different (p < 0.05) except for the general health condition section. Patients in the CR group scored higher in physical functioning, physical role, body pain, vitality, social role, emotional role and mental health. Scores obtained from different time points also varied significantly (p < 0.05), with those of one month and one year after operation being noticeably higher than the preoperative ones. CONCLUSIONS Both complete and incomplete revascularization methods can effectively improve the short- and long-term quality of life in patients with multivessel coronary artery disease. However, complete revascularization can produce better results.

Abstract
Recent transcriptomic analysis of the bovine Y chromosome revealed abundant presence of multi-copy protein coding gene families on the male-specific region of the Y chromosome (MSY). Copy number variations (CNVs) of several MSY genes are closely related to semen quality and male reproduction in cattle. However, the CNVs of MSY genes in water buffalo are largely unknown. Therefore, this study aimed to investigate the CNVs of HSFY and ZNF280BY of 298 buffaloes from 17 populations distributed in China, Vietnam and Laos using quantitative PCR. Our results revealed that the median copy numbers of the HSFY and ZNF280BY genes were 47 (ranging from 20 to 145) and 269 (ranging from 73 to 974) respectively. In conclusion, this study indicated that HSFY and ZNF280BY showed abundant CNVs within swamp buffalo populations.

Abstract
OBJECTIVE To validate the antiviral effect of oxymatrine against hepatitis C virus (HCV) in the construction of the cell culture-based infectious virus system HCVcc. METHODS An HCVcc system was established by infecting Huh7.5.1 cells with the J6 adapted virus (J6cc). Cells of the HCVcc system were then treated with different concentrations of oxymatrine for 24 h, 48 h and 72 h, or left untreated (controls). MTT assay was used to detect effects on proliferation. Real-time quantitative PCR was used to detect effects on HCV mRNA expression level, and immunofluorescence was used to detect effects on HCV protein expression. Data were expressed as mean±standard deviation, and statistically assessed using one-way ANOVA and one-sample t-test. RESULTS Treatment with 2, 4, 8 and 12 mg/mL of oxymatrine for 24 h inhibited proliferation of the J6cc-infected cells by 8.4%, 15.2%, 29.6% and 48.6% respectively, 48 h treatment inhibited by 14.3%, 25.7%, 46.1% and 66.4% respectively, and 72 h treatment inhibited by 36.5%, 46.6%, 70.6% and 85.4% respectively. Thus, the effects of oxymatrine were time- and dose-dependent (P < 0.05). The mRNA expression level in the oxymatrine-treated cells of the HCVcc system was 0.59 ± 0.12, which was significantly lower than that in the control cells (P < 0.05). Moreover, as the oxymatrine concentration increased from 2 mg/mL to 12 mg/mL, the expression levels of HCV proteins also showed a decreasing trend. CONCLUSION We successfully constructed a J6cc infection HCVcc system and verified the antiviral effect of oxymatrine against HCV.

Abstract
microRNAs could be mechanosensitive and emerge as critical posttranscriptional regulators in the bone-remodeling process. During orthodontic tooth movement (OTM), the application of mechanical force induces alveolar bone remodeling, but whether microRNAs respond to orthodontic force and contribute to OTM is unknown. microRNA-21 (miR-21) has been previously reported in vitro to mediate stretch-induced osteogenic differentiation of periodontal ligament stem cells and support osteoclast differentiation. In this study, the authors show that miR-21 responded to orthodontic force in periodontal tissue in a dose- and time-dependent manner and regulated the osteogenesis of human periodontal ligament stem cells following OTM. Using mmu-miR-21-deficient (miR-21-/-) mice, the authors discovered that mmu-miR-21 deficiency inhibited OTM and prevented force-induced maxillary bone loss. The authors found that miR-21-/- mice showed a normal skeletal phenotype in development and a similar alveolar bone formation rate to wild-type mice postnatally. During OTM, mmu-miR-21 regulated force-induced alveolar osteoblastogenesis in the tensile side, while no effects were detected in the compressive side. However, miR-21-/- mice showed inhibited alveolar osteoclastogenesis when compared with wild-type mice. During OTM, mmu-miR-21 deficiency blocked alveolar bone resorption in both the compressive and tensile sides. To dissect the mechanism by which miR-21 regulates alveolar bone remodeling, the authors screened the reported functional targets of miR-21 and found that periodontal expression of programmed cell death 4 ( Pdcd4) was inhibited following OTM. Furthermore, mmu-miR-21 deficiency removed the suppression of Pdcd4 at both the mRNA and protein levels in the periodontium, resulting in upregulation of the downstream effector C-fos. Further analysis of OTM under lipopolysaccharide-induced periodontal inflammation showed that mmu-miR-21 mediated lipopolysaccharide (LPS)-accelerated OTM and that mmu-miR-21 deficiency blocked lipopolysaccharide-induced maxillary bone loss. In summary, these findings reveal a previously unrecognized mechanism that a microRNA can modulate OTM and alveolar bone remodeling under both normal and inflammatory microenvironments in vivo.

Abstract
OBJECTIVE Irisin, a newly discovered myokine, can drive the browning of white adipocytes to control body weight or mitigate obesity progression through regulating energy metabolism. However, the underlying mechanisms or specific signal pathways of exercise-induced irisin on the management of obesity are still unclear. MATERIALS AND METHODS Totally 30 rats were subjected to high fat diet (HFD) feeding for 8 weeks to establish the rat model with obesity successfully. HFD-induced obese model rats were provided with 8 weeks swimming intervention at moderate intensity for exploring the treatment of obesity through exercise intervention. In addition, another 15 rats were subjected to HFD feeding coupled with total 16 weeks swimming intervention at a moderate intensity from the beginning of the experiment, which was used for exploring the prevention of obesity through exercise intervention. Blood and gastrocnemius samples were harvested from obese rats after swimming intervention to explore its specific signal pathways through ELISA analysis and Western blotting. RESULTS HFD feeding of rats for 8 weeks could lead to the obesity due to the disorders of lipid metabolism. Totally 8 weeks swimming intervention at moderate intensity for rats with obesity could obviously alleviate the progression of obesity and 16 weeks swimming intervention from the beginning of the experiment could significantly inhibit the development of obesity. Meanwhile, swimming intervention could result in an increased phosphorylation of AMPK and up-regulation of irisin and PGC-1α as the biomarkers of energy metabolism. CONCLUSION Exercise intervention can activate PGC-1α-dependent irisin to induce the browning of white adipocytes, thus inhibiting or alleviating the occurrence and development of obesity.

Abstract
Metabolic syndrome, a cluster of 3 or more risk factors for cardiovascular disease, is associated with periodontal disease, but few studies have been prospective in design. This study's aim was to determine whether metabolic syndrome predicts tooth loss and worsening of periodontal disease in a cohort of 760 men in the Department of Veterans Affairs Dental Longitudinal Study and Normative Aging Study who were followed up to 33 y from 1981 to 2013. Systolic and diastolic blood pressures were measured with a standard mercury sphygmomanometer. Waist circumference was measured in units of 0.1 cm following a normal expiration. Fasting blood samples were measured in duplicate for glucose, triglyceride, and high-density lipoprotein. Calibrated periodontists served as dental examiners. Periodontal outcome events on each tooth were defined as progression to predefined threshold levels of probing pocket depth (≥5 mm), clinical attachment loss (≥5 mm), mobility (≥0.5 mm), and alveolar bone loss (≥40% of the distance from the cementoenamel junction to the root apex, on radiographs). Hazards ratios (95% confidence intervals) of tooth loss or a periodontitis event were estimated from tooth-level extended Cox proportional hazards regression models that accounted for clustering of teeth within individuals and used time-dependent status of metabolic syndrome. Covariates included age, education, smoking status, plaque level, and initial level of the appropriate periodontal disease measure. Metabolic syndrome as defined by the International Diabetes Federation increased the hazards of tooth loss (1.39; 1.08 to 1.79), pocket depth ≥5 mm (1.37; 1.14 to 1.65), clinical attachment loss ≥5 mm (1.19; 1.00 to 1.41), alveolar bone loss ≥40% (1.25; 1.00 to 1.56), and tooth mobility ≥0.5 mm (1.43; 1.07 to 1.89). The number of positive metabolic syndrome conditions was also associated with each of these outcomes. These findings suggest that the metabolic disturbances that comprise the metabolic syndrome may play a role in the development or worsening of periodontitis.

Abstract
Currently, Luminex technology based on the PCR sequence-specific oligonucleotide (SSO) probe method has been widely used for HLA genotyping in the immunogenetics laboratories. Here, we reported a case with HLA-B allele dropout by Luminex technology. The initial HLA-B result of the Luminex method with a commercial agent kit was inconclusive, and then, the result of PCR-SBT technology indicated the dropout as a HLA-B*58 allele. Subsequently, the full-length sequence of HLA-B allele was determined by TOPO-TA cloning, and a novel allele B*58:01:01:02 was identified in the individual. Compared with HLA-B*58:01:01:01, the novel allele showed some nucleotides difference at 509 C>T, 521 T>G and CCC insertion in position 503 of intron 2. According to the full-length sequence, the new mutations of intron 2 were contributed to HLA-B locus allele dropout in the sample. Our results indicated multiplatform should be used to improve the HLA typing accuracy when a conclusive HLA genotype cannot be determined.
