Abstract
OBJECTIVE The aim of the present study is to explore the mechanism of action of several proteins, including Epstein-Barr virus (EBV), B-cell lymphoma (Bcl)-2, p53, c-Myc and retinoblastoma (Rb), in Non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS Between July 2010 and July 2015, samples of 142 patients with pathologically confirmed NHL which presented at our institution were included in the observation group. In addition, samples from 55 patients with hyperplastic lymphadenitis presented during the same period were enrolled as control group. The expressions of EBV (+), p53(+), Bcl-2(+), Rb(-) and c-Myc(+) were determined and compared PATIENTS AND METHODS Between July 2010 and July 2015, samples of 142 patients with pathologically confirmed NHL which presented at our institution were included in the observation group. In addition, samples from 55 patients with hyperplastic lymphadenitis presented during the same period were enrolled as control group. The expressions of EBV (+), p53(+), Bcl-2(+), Rb(-) and c-Myc(+) were determined and compared among different subtypes and stages of NHLs of observation group. Besides, the correlation of EBV with p53, Bcl-2, Rb and c-Myc were investigated in NHLs of observation group. RESULTS In the observation group, the expression rates of EBV(+), p53(+), Bcl-2(+), Rb(-), and c-Myc(+) were significantly higher than those, respectively, in the control group (p < 0.05). No significant correlation was observed between EBV expression and the expressions of p53, Bcl-2, Rb and c-Myc in the observation group (p > 0.05). The expression rates of p53(+) and Bcl-2(+) were significantly higher in aggressive and highly-aggressive NHLs than in indolent NHLs of the observation group (p < 0.05). The expressions of EBV(+), p53(+), Bcl-2(+), Rb(-), and c-Myc(+) were significantly higher in stage III-IV NHLs than in stage I-II NHLs (p < 0.05). CONCLUSIONS The expressions of EBV(+), p53(+), Bcl-2(+), Rb(-), and c-Myc(+) are closely associated with NHL pathogenesis. Expressions of these proteins are higher in later stages of NHLs, and expressions of p53(+) and Bcl-2(+) are higher in more aggressive NHLs.

Abstract
OBJECTIVES To carrying out an integrated analysis on regional environment and human health in China and to detect the association between longevity and daily element intake from food and drinking water. DESIGN Cross-sectional study. SETTING All the 18 cities and counties in Hainan Province. MEASUREMENTS The distribution of elderly population and longevity indexes at a county level in Hainan Province were investigated. Quality of food and drinking water in Hainan was evaluated by comparing the chemical elements with National Standards. In addition, the association between element concentrations in food and water and longevity was examined using spearman's rank correlation. RESULTS The proportion of elderly people is higher in the northern part of the province compared with southern counties. Food contributes a greater proportion of daily element intake than drinking water. Compared with the National Standards, reaching rates for elements were over 85% for both food and drinking water. There was a positive correlation between daily intake of Cu, Se, and Zn from food and water and aging and longevity indexes, and a negative correlation between Pb intake and these indexes. CONCLUSION The quality of food and water in Hainan Province are good and that, compared with water, food is a more important source of trace elements. An appropriate supply of Cu, Se, and Zn is important, whereas excessive intake of Pb should be avoided. The findings also provide basic data to support further studies on regional variations in longevity and their relationship to diet and drinking water.

Abstract
The aim of the present work was to investigate the effect and the mechanism of growth inhibition on mouse H22 hepatocarcinoma cell of ascitic tumor induced by cartilage polysaccharides (PS). Our results showed that PS prolonged the survival time of the mice and increased the life span. In addition, PS induced the apoptosis of the H22 cells with the typical apoptotic morphological and biochemical changes confirmed by HE staining and TUNEL assay. The subsequent analysis of cell cycle distribution and relevant proteins revealed that decrease of cells in G0/G1phase and a G2/M arrest might due to the down-regulation of Cyclin D1 and AFP and up-regulation of P21 proteins. Moreover, BCL2/BAX caspase-activated Fas pathway was activated in PS-induced H22 apoptosis.

Abstract
The aim of this study was to construct lentivirus-mediated short hairpin RNA (shRNA) vectors targeting the duck MSTN gene and investigate whether these vectors can affect the development of duck primary cultured embryonic myoblasts. MSTN mRNA levels in the myoblasts were detected using quantitative real-time polymerase chain reaction (PCR), cell proliferation was assessed by MTT assays and cell differentiation was assayed by photography. MSTN mRNA levels in PLL3.7-MSTN-shRNA1, PLL3.7-MSTN-shRNA2 and PLL3.7-MSTN-shRNA3 lentivirus-mediated shRNA groups were reduced by 61.6%, 76.9% and 79.1%, respectively, compared to control cells. Down-regulation of MSTN in duck embryonic myoblasts stimulated cell proliferation and inhibited differentiation, accompanied by a greater than twofold down-regulation of MyoD expression and up-regulation of Myf5 expression. These results revealed that silencing of MSTN changes the development of duck embryonic myoblasts by regulating the expression level of MyoD and Myf5 genes.

Abstract
Nestin is widely expressed in numerous tumors and has become a diagnostic and prognostic indicator. However, the exact mechanism by which nestin contributes to tumor malignancy remains poorly understood. Here, we found marked upregulation of nestin expression in highly proliferative and invasive gastrointestinal stromal tumor (GIST) specimens. Nestin knockdown in GIST cells reduced the proliferative and invasive activity owing to a decrease of mitochondrial intracellular reactive oxygen species (ROS) generation. Furthermore, nestin was co-localized with mitochondria, and knockdown of nestin increased mitochondrial elongation and influenced the mitochondrial function, including oxygen consumption rates, ATP generation and mitochondrial membrane potential and so on. In exploring the underlying mechanism, we demonstrated nestin knockdown inhibited the mitochondrial recruitment of Dynamin-related protein1 and induced the change of mitochondrial dynamics. Thus, nestin may have an important role in GIST malignancy by regulating mitochondrial dynamics and altering intracellular ROS levels. The findings provide new clues to reveal mechanisms by which nestin mediates the proliferation and invasion of GISTs.

Abstract
The aim of this study is to investigate a food effect on the single-dose pharmacokinetics and tolerability of subutinib maleate capsules in healthy Chinese volunteers. The author evaluated the effect of being under a fasting or fed state at the time of drug intake on the single-dose of subutinib maleate capsules in a randomized, balanced, single-dose, 2-treatment (fasting and fed), 2-period design with a 3-week washout period. The end points were the maximum plasma drug concentration (Cmax) and areas under the plasma-concentration curve (AUC) for 336 h exposure (AUC0-336) and total exposure (AUC0-∞). All volunteers completed the whole study without side effects being observed. For subutinib, Cmax were 6.13 and 5.04 ng·mL(-1), and AUC0-336 were 278.4 and 304.5 h·ng·mL(-1) in the fasting and the fed state, respectively. For active metabolite, Cmax were 0.90 and 0.61 ng·mL(-1), and AUC0-336 were 65.5 and 56.4 h·ng·mL(-1) in the fasting and the fed state, respectively. The authors showed that food intake was associated with a slight increase in AUC values but decrease in Cmax of subutinib, and it was associated with a decrease both in AUC and Cmax of active metabolite.

Abstract
OBJECTIVE Acute viral myocarditis (VM) is an important cause of sudden cardiac death and heart failure in healthy young person. Direct virus-mediated injury and secondary immune reactions, including inflammatory and autoimmune responses, have been reported both in animal models and in humans. Recently, genetic variation has been confirmed related to myocarditis process and susceptibility to VM. In this study, we scanned 339bp of pri-miR-10a coding region in CVB3 VM patients, want to found genetic relations between miR-10a and VM susceptibility. PATIENTS AND METHODS The secondary structure of two genotype 220 bp pri-miR-10a sequences was predicted using RNAfold web server. In vitro biological functional study concluded dual luciferase assay and Western blotting. RESULTS We found the rare allele T of rs3809783 was accumulated in VM patients and related to VM significantly. Subsequently, we confirmed that ITCH, a NK-κB signaling suppressor, is a direct target of miR-10a. In vitro biological functional study indicated that this site variation reduced mature miR-10a expression and induced a down-regulated cytokine secretion in the cell culture supernatant. CONCLUSIONS The results suggest that the rare allele T in pri-miR-10a coding region should be involved in the CVB3 caused VM pathogenesis through weakening host anti-virus immune response. This site may be used for clinical genetic evaluation for VM susceptibility.

Abstract
In the period of gestation, delivery and post-delivery, fear and tension produced in puerperae are likely to evolve into depression as they worry too much about delivery pain. In recent years, it has been noted that stressful events during this period aggravate postpartum depression. To discuss the effect of these childbirth-related stressful events on neuroendocrine functions of patients with postpartum depression, 300 full-term puerperae who had been admitted to the Beijing Obstetrics and Gynecology Hospital, Capital Medical University between October, 2011 and October, 2013 and who had suffered from stressful childbirth-related events were enrolled as a study group. This group was divided into six subgroups, i.e., A, B, C, D, E and F, based on the number of stressful events they had suffered which were labeled by numbers 1 to 6. Additionally, 100 puerperae from the same hospital who had not suffered from childbirth-related stressful events were taken as controls. Relevant clinical indexes, including serum adrenocorticotropic hormone (ACTH), plasma 5-hydroxytryptamine (5-HT), noradrenaline ELISA (NE), dopamine (DA) and cortisol level were measured and compared. It was found that incidence probability of postpartum depression was significantly different between the study group (13.67%, 41/300) and the control group (7%, 7/100). Moreover, the incidence probability of postpartum depression of puerperae suffering from no less than 4 childbirth-related stressful events was higher than those suffering from no more than 3, and the difference was statistically significant (P<0.05). Thus, stress disorders caused by these events are one of the important pathogenic factors of postpartum depression.

Abstract
A direct calorimetric measurement of the overall enthalpy change associated with self-assembly of organic monolayers at the liquid-solid interface is for most systems of interest practically impossible. In previous work we proposed an adapted Born-Haber cycle for an indirect assessment of the overall enthalpy change by using terephthalic acid monolayers at the nonanoic acid-graphite interface as a model system. To this end, the sublimation enthalpy, dissolution enthalpy, the monolayer binding enthalpy in vacuum, and a dewetting enthalpy are combined to yield the total enthalpy change. In the present study the Born-Haber cycle is applied to 4,4'-stilbenedicarboxylic acid monolayers. A detailed comparison of these two aromatic dicarboxylic acids is used to evaluate and quantify the contribution of the organic backbone for stabilization of the monolayer at the nonanoic acid-graphite interface.
