Abstract
BACKGROUND Population aging is an important problem worldwide, with activity and quality of daily living commonly reduced in elderly people. leading to increased hospitalization and mortality rates, and substantial individual and social burdens. OBJECTIVE This study was designed to investigate the associations of serum homocysteine levels with activity and quality of daily living in Chinese centenarians for the first time. PARTICIPANTS The China Hainan Centenarian Cohort Study was performed in 18 cities and counties of Hainan Province. MAIN MEASURES Home interview, physical examination and blood analysis were performed in 787 centenarians following standard procedures. KEY RESULTS The median age was 102 years, ranging between 100 and 115 years. There were 634 females (80.6%) and 153 males (19.4%) in all. The median level of serum homocysteine was 23.80 (18.80-29.90) umol/L, whereas median values of Barthel Index and EuroQol 5 Dimensions were 85(60-95) and 0.661(0.558-0.766), respectively. The centenarians with serum homocysteine levels ≥23.8μmol/L were more likely to had lower values of Barthel Index and EuroQol 5 Dimensions than those with serum homocysteine levels <23.8μmol/L (P<0.05 for all). In multivariate linear regression analyses, serum homocysteine levels were significantly associated with Barthel Index and EuroQol 5 Dimensions (P<0.05 for all). CONCLUSIONS Serum homocysteine levels had important associations with activity and quality of daily living in Chinese centenarians. Future research should focus on the value of intervening in serum homocysteine levels by supplying folic acid (vitamin B9) and vitamin B12 on improving activity and quality of daily living in elderly people.

Abstract
OBJECTIVES This study aims to investigate the prevalence of vitamin D deficiency in Chinese centenarians and to identify the factors associated with vitamin D deficiency. DESIGN Cross-sectional population-based study. SETTING Hainan province in the south of China. PARTICIPANTS 943 subjects aged 100 years old and older. METHODS Details on sociodemographics and lifestyle characteristics were collected using a structured questionnaire. Anthropometrics and blood samples were obtained. Vitamin D deficiency was defined as serum 25-hydroxyvitamin D concentration < 20ng/mL (50nmol/L). RESULTS The overall prevalence of vitamin D deficiency among these 943 centenarians was 39.9% (376 subjects) and the mean serum vitamin D concentrations were 22.7±9.5 (ng/mL). Female centenarians had higher prevalence of vitamin D deficiency than male (44.0% vs. 21.7%, P <0.001). Multivariate logistic regression analyses showed that being female, urban residency, lower body mass index, higher serum parathyroid hormone levels, no fish consumption, and less sun exposure time were all significant and independent determinants of vitamin D deficiency. No significant associations of vitamin D deficiency with ethnic, education, geographic location, tea drinking, alcohol use, or smoking were found in this study. CONCLUSION Vitamin D deficiency was common in Chinese centenarians, especially in women. Given that vitamin D deficiency is linked to numerous adverse health outcomes, dietary, outdoor activities and other intervention measures are needed to correct vitamin D deficiency in this population.

Abstract
BACKGROUND Activity of daily living declines in female elderly, which not only increases hospitalization and mortality rates, but also aggravates individual and societal burden. Large samples are needed to elucidate the relationships of plasma sex hormone levels with activity of daily living in Chinese female centenarians to better understand the effects of hormone-replacing therapy. OBJECTIVE As the first time in the world, the current study was designed to investigate the relationships of plasma sex hormone levels with activity of daily living in Chinese female centenarians. PARTICIPANTS China Hainan Centenarian Cohort Study was carried out in 18 cities and counties of Hainan Province. MAIN MEASURES Home interview, physical examination and blood analysis were carried out in 583 female centenarians following standard procedures. Barthel Index was used to assess the activity of daily living. KEY RESULTS Median age of all female centenarians was 102 years, with the range from 100 to 115 years. Median values of Barthel Index were 85(60-90). In multivariate linear regression analyses, Barthel Index values were inversely associated with plasma luteinizing hormone (LH), follicle-simulating hormone (FSH), testosterone, progesterone and estradiol levels (P<0.05 for all). CONCLUSION Plasma sex hormone levels, including LH, FSH, testosterone, progesterone and estradiol, had significant relationships with activity of daily living in Chinese female centenarians.

Abstract
Background Targeted methylation sequencing of plasma cell-free DNA (cfDNA) has a potential to expand liquid biopsies to patients with tumors without detectable oncogenic alterations, which can be potentially useful in early diagnosis. Patients and methods We developed a comprehensive methylation sequencing assay targeting 9223 CpG sites consistently hypermethylated according to The Cancer Genome Atlas. Next, we carried out a clinical validation of our method using plasma cfDNA samples from 78 patients with advanced colorectal cancer, non-small-cell lung cancer (NSCLC), breast cancer or melanoma and compared results with patients' outcomes. Results Median methylation scores in plasma cfDNA samples from patients on therapy were lower than from patients off therapy (4.74 versus 85.29; P = 0.001). Of 68 plasma samples from patients off therapy, methylation scores detected the presence of cancer in 57 (83.8%), and methylation-based signatures accurately classified the underlying cancer type in 45 (78.9%) of these. Methylation scores were most accurate in detecting colorectal cancer (96.3%), followed by breast cancer (91.7%), melanoma (81.8%) and NSCLC (61.1%), and most accurate in classifying the underlying cancer type in colorectal cancer (88.5%), followed by NSCLC (81.8%), breast cancer (72.7%) and melanoma (55.6%). Low methylation scores versus high were associated with longer survival (10.4 versus 4.4 months, P < 0.001) and longer time-to-treatment failure (2.8 versus 1.6 months, P = 0.016). Conclusions Comprehensive targeted methylation sequencing of 9223 CpG sites in plasma cfDNA from patients with common advanced cancers detects the presence of cancer and underlying cancer type with high accuracy. Methylation scores in plasma cfDNA correspond with treatment outcomes.

Abstract
Ancient DNA research has been revolutionized following development of next-generation sequencing platforms. Although a number of such platforms have been applied to ancient DNA samples, the Illumina series are the dominant choice today, mainly because of high production capacities and short read production. Recently a potentially attractive alternative platform for palaeogenomic data generation has been developed, the BGISEQ-500, whose sequence output are comparable with the Illumina series. In this study, we modified the standard BGISEQ-500 library preparation specifically for use on degraded DNA, then directly compared the sequencing performance and data quality of the BGISEQ-500 to the Illumina HiSeq2500 platform on DNA extracted from 8 historic and ancient dog and wolf samples. The data generated were largely comparable between sequencing platforms, with no statistically significant difference observed for parameters including level (P = 0.371) and average sequence length (P = 0718) of endogenous nuclear DNA, sequence GC content (P = 0.311), double-stranded DNA damage rate (v. 0.309), and sequence clonality (P = 0.093). Small significant differences were found in single-strand DNA damage rate (δS; slightly lower for the BGISEQ-500, P = 0.011) and the background rate of difference from the reference genome (θ; slightly higher for BGISEQ-500, P = 0.012). This may result from the differences in amplification cycles used to polymerase chain reaction–amplify the libraries. A significant difference was also observed in the mitochondrial DNA percentages recovered (P = 0.018), although we believe this is likely a stochastic effect relating to the extremely low levels of mitochondria that were sequenced from 3 of the samples with overall very low levels of endogenous DNA. Although we acknowledge that our analyses were limited to animal material, our observations suggest that the BGISEQ-500 holds the potential to represent a valid and potentially valuable alternative platform for palaeogenomic data generation that is worthy of future exploration by those interested in the sequencing and analysis of degraded DNA.

Abstract
Technological innovation and increased affordability have contributed to the widespread adoption of genome sequencing technologies in biomedical research. In particular large cancer research consortia have embraced next generation sequencing, and have used the technology to define the somatic mutation landscape of multiple cancer types. These studies have primarily utilised the Illumina HiSeq platforms. In this study we performed whole genome sequencing of three malignant pleural mesothelioma and matched normal samples using a new platform, the BGISEQ-500, and compared the results obtained with Illumina HiSeq X Ten. Germline and somatic, single nucleotide variants and small insertions or deletions were independently identified from data aligned human genome reference. The BGISEQ-500 and HiSeq X Ten platforms showed high concordance for germline calls with genotypes from SNP arrays (>99%). The germline and somatic single nucleotide variants identified in both sequencing platforms were highly concordant (86% and 72% respectively). These results indicate the potential applicability of the BGISEQ-500 platform for the identification of somatic and germline single nucleotide variants by whole genome sequencing. The BGISEQ-500 datasets described here represent the first publicly-available cancer genome sequencing performed using this platform.

Abstract
BACKGROUND Chronic hepatitis C virus (HCV) infection is the leading cause of cirrhosis and hepatocellular carcinoma (HCC) in the United States (US) and an emerging cause in China. AIM To compare the clinical characteristics of hepatitis C patients in the US and China, and factors influencing disease stage. METHODS Prospective study of 2 cohorts of HCV patients recruited at 1 site in the US and 3 sites in China. Standardised questionnaire on risk factors and medical history were used and diagnosis of cirrhosis and HCC was based on pre-defined criteria. RESULTS One thousand nine hundred and fifty seven patients (1000 US and 957 China) were enrolled. US patients were more likely to be men (61.4% vs 48.5%), older (median age 57 vs 53 years), obese (38.4% vs 16.8%) and diabetic (21.8% vs 10.8%). A significantly higher per cent of US patients had cirrhosis (38.2% vs 16.0%) and HCC (14.1% vs 2.7%). Investigator estimated time at infection in US was 10 years earlier than in Chinese patients but US patients were more likely to have advanced disease even after stratifying for duration of infection. Study site in the US, older age, truncal obesity, diabetes and prior HCV treatment were significant predictors of advanced disease on multivariate analysis. CONCLUSIONS HCV patients in the US had more advanced liver disease than those in China. We speculate that underlying fatty liver disease may be a major contributor to this difference, and management of glycometabolic abnormalities should occur in parallel with anti-viral therapy to achieve optimal outcomes.

Abstract
Translationally controlled tumor protein(TCTP) has been implicated in the regulation of apoptosis, DNA repair and drug resistance. However, the underlying molecular mechanisms are poorly defined. To better understand the molecular mechanisms underlying TCTP involved in cellular processes, we performed an affinity purification-based proteomic profiling to identify proteins interacting with TCTP in human cervical cancer HeLa cells. We found that a group of proteins involved in DNA repair are enriched in the potential TCTP interactome. Silencing TCTP by short hairpin RNA in breast carcinoma MCF-7 cells leads to the declined repair efficiency for DNA double-strand breaks on the GFP-Pem1 reporter gene by homologous recombination, the persistent activation and the prolonged retention of γH2AX and Rad51 foci following ionizing radiation. Reciprocal immunoprecipitations indicated that TCTP forms complexes with Rad51 in vivo, and the stability maintenance of Rad51 requires TCTP in MCF-7 cells under normal cell culture conditions. Moreover, inactivation of TCTP by sertraline treatment enhances UVC irradiation-induced apoptosis in MCF-7 cells, and causes sensitization to DNA-damaging drug etoposide and DNA repair inhibitor olaparib. Thus, we have identified an important role of TCTP in promoting DNA double-stand break repair via facilitating DNA homologous recombination processes and highlighted the great potential of TCTP as a drug target to enhance conventional chemotherapy for cancer patients with high levels of TCTP expression.

Abstract
Background Cell-free DNA (cfDNA) from plasma offers easily obtainable material for KRAS mutation analysis. Novel, multiplex, and accurate diagnostic systems using small amounts of DNA are needed to further the use of plasma cfDNA testing in personalized therapy. Patients and methods Samples of 16 ng of unamplified plasma cfDNA from 121 patients with diverse progressing advanced cancers were tested with a KRASG12/G13 multiplex assay to detect the seven most common mutations in the hotspot of exon 2 using droplet digital polymerase chain reaction (ddPCR). The results were retrospectively compared to mutation analysis of archival primary or metastatic tumor tissue obtained at different points of clinical care. Results Eighty-eight patients (73%) had KRASG12/G13 mutations in archival tumor specimens collected on average 18.5 months before plasma analysis, and 78 patients (64%) had KRASG12/G13 mutations in plasma cfDNA samples. The two methods had initial overall agreement in 103 (85%) patients (kappa, 0.66; ddPCR sensitivity, 84%; ddPCR specificity, 88%). Of the 18 discordant cases, 12 (67%) were resolved by increasing the amount of cfDNA, using mutation-specific probes, or re-testing the tumor tissue, yielding overall agreement in 115 patients (95%; kappa 0.87; ddPCR sensitivity, 96%; ddPCR specificity, 94%). The presence of ≥ 6.2% of KRASG12/G13 cfDNA in the wild-type background was associated with shorter survival (P = 0.001). Conclusion(s) Multiplex detection of KRASG12/G13 mutations in a small amount of unamplified plasma cfDNA using ddPCR has good sensitivity and specificity and good concordance with conventional clinical mutation testing of archival specimens. A higher percentage of mutant KRASG12/G13 in cfDNA corresponded with shorter survival.

Abstract
OBJECTIVE P27Kip1 is the one of the negative regulators of the cell cycle that plays an important role in regulating cell cycle and inhibiting cell proliferation by restraining cell in G1 phase. P27Kip1 downregulation maybe related to the occurrence of oral squamous cell carcinoma (OSCC). It was found that miR-155 significantly upregulated in OSCC tissue. Bioinformatics analysis revealed that miR-155 may bind with the 3'-UTR of p27Kip1. This study investigated the role of miR-155 in regulating p27Kip1 and affecting Tca8113 cell proliferation, cycle, and apoptosis. PATIENTS AND METHODS A total of 46 cases of OSCC patients received treatment in our hospital were enrolled to obtain tumor tissue. Another 25 normal oral mucosa samples were selected as control to detect the relationship between miR-155 and p27Kip1 expressions. Dual luciferase assay was adopted to confirm the targeted relationship between miR-155 and p27Kip1. Flow cytometry was applied to test cell apoptosis and cell cycle. CCK-8 assay was used to evaluate cell proliferation. Caspase-3 activity was detected by spectrophotometry. RESULTS MiR-155 upregulated, while p27Kip1 declined in OSCC tissue compared with normal oral mucosa. Their expressions were related to TNM stage. MiR-155 targeted suppressed p27Kip1 expression. MiR-155 mimic and/or pEGFP-p27Kip1 transfection obviously declined p27Kip1 expression, blocked cell cycle in G1 phase, reduced cell proliferation, enhanced Caspase-3 activity, and increased cell apoptosis in Tca8113 cells. CONCLUSIONS MiR-155 increased, while p27Kip1 reduced in OSCC tissue. Inhibition of miR-155 upregulated p27Kip1 expression, blocked cell cycle in G1 phase, weakened cell proliferation, and induced cell apoptosis.

Abstract
Objective: To establish a method for determination trace bismuth in blood by atomic fluorescence spectrometry (AFS) . Methods: 4.0 ml nitric acid and 1.0 ml perchloric acid was added into 1.0 ml blood sample then through automation graphite digestion instrument digested, after that 1.0 ml thiocarbamide-vitamin (10%) was injected, 8% HCl constant volume to 10.0 ml, the bismuth was detected by atomic fluorescence spectrometry with 5.0 ml digestive sample. Results: The method showed a linear relationship within the range of 0.4-50.0 μg/L (r=0.999 7) . The within-run and between-run relative standard deviations (RSD) of repetitive measurement at 10.0, 20.0, 40.0 μg/L concentration levels were 2.2%-4.9% and 3.0%-4.0%. The detection limit was 0.032 μg/L. The recoveries of bismuth were 93.0%-103.9%. Conclusion: This method is low detection limit, good accurate and high sensitivity. It has been applied for determination of trace bismuth in blood samples those who need occupation health examination or poisoning diagnosis.

Abstract
BACKGROUND The purpose of this meta-analysis was to compare the outcomes of external fixation and flexible intramedullary nails for femoral fractures in children between 5 and 15 years of age based on the current evidence. MATERIALS AND METHODS We searched relevent studies in the following database: Cochrane library, PubMed and EMABASE up to May 2014. All randomized controlled trials, Clinical controlled trials and retrospective controlled studies comparing external fixation and flexible intramedullary nails in femoral fractures of children were included. Data was extracted independently for meta-analysis. RESULTS Seven trials altogether involving 338 cases of femoral fractures of children treated by external fixation (128 cases) and flexible intramedullary nails (210 cases) were included in the meta-analysis. Results showed that flexible intramedullary nails was superior to external fixation in less time to union , lower postoperative infection rate and refracture rate . It may not increase delayed union, Limb-length discrepancy , pain and bursitis . Both fixations obtained a similar patient satisfaction. CONCLUSION Flexible intramedullary nail had greater advantages for the treatment of femoral fractures in children aged 5-15 years, compared to external fixation based on current meta-analysis. This conclusion will ultimately require rigorous and adequately powered randomized controlled trials to be proved.
