Abstract
Endothelial dysfunction is closely associated with hypertension. Protection of vascular endothelial cell is the key to prevention and treatment of hypertension. Uncaria rhynchophylla total alkaloids and Semen Raphani soluble alkaloid, isolated from traditional Chinese medicine Uncaria rbyncbopbylla and Semen Raphani respectively, exhibit properties of anti-hypertension and protection of blood vessels. In the present study, we observed the protective effect of the combined use of Uncaria rhynchophylla total alkaloids and Semen Raphani soluble alkaloid to the vascular endothelial cell in N'-nitro-L-arginine-induced hypertensive rats and investigate the preliminary mechanism. Blood pressure was detected by non-invasive rats tail method to observe the anti-hypertension effect of drugs. Scanning electron microscopy was used to observe the integrity or shedding state of vascular endothelial cell. The amount of circulating endothelial cells and CD54 and CD62P expression on circulating endothelial cells were tested to evaluate the endothelium function. In this study, we found that the Uncaria rhynchophylla total alkaloids and Semen Raphani soluble alkaloid compatibility can effectively lower the blood pressure, improve the structural integrity of vascular endothelium, and significantly reduce the number of circulating endothelial cells. Furthermore, the mean fluorescence intensity of CD54 and CD62P expressed showed decrease after the intervention of Uncaria rhynchophylla total alkaloids and Semen Raphani soluble alkaloid compatibility. In conclusion, the combination of effective components of the Uncaria rhynchophylla total alkaloids and Semen Raphani soluble alkaloid demonstrated good antihypertension effect and vascular endothelium protective effect. The preliminary mechanism of the protective effect may attribute to relieve the overall low-grade inflammation.

Abstract
OBJECTIVES To investigate the extent of cigarette smoking, knowledge of health hazards and attitudes towards the ban of smoking in Shantou, China, as causes for failure to control smoking. STUDY DESIGN Environmental monitoring and population survey. METHODS Particulate matter (PM2.5) measurements were conducted in randomly selected public places (restaurants, non-alcoholic drink shops and internet bars) and exposure-related health hazards were evaluated. University students and adult citizens were randomly selected to determine their extent of cigarette smoking, knowledge of health hazards and attitude towards the ban of smoking in public places. The collected data were used to evaluate possible causes and solutions to the smoking problem. RESULTS From PM2.5 measurements, the average indoor to outdoor concentrations in non-smoking restaurants were 33.4 vs. 30.6 μg/m(3), P > 0.05; average indoor of smoking restaurants was 350.0% higher, P < 0.05; internet bars was 395.7% higher, P < 0.05; and non-alcoholic drink shops was 650.2% higher, P > 0.001. From our survey of 1100 university students: 1) 17.5% and 7.5% were active male and female smokers, respectively; and 2) 57.5% of students would accept a smoke-ban policy. From 502 adult citizens: 1) 27.5% were active male smokers; 2) Approximately 40 and 60% had inadequate knowledge of health hazards from smoking and second-hand smoke exposure; and 3) >90% of them would accept a smoke-ban policy. CONCLUSIONS Our data indicate that failure to ban smoking was not caused by resistance from smokers but inadequate (national and local) government effort to educate the public and to enforce existing policy. The data suggest that development of a citizen-based approach, in collaboration with willing officials, may be highly successful in the control of cigarette smoking in China.

Abstract
PDZ domains are common 80- to 90-amino-acid regions named after the first three proteins discovered to share these domains: postsynaptic density 95, discs large, and zonula occludens. PDZ domain-containing proteins typically interact with the C-terminus of membrane receptors. Glutamate receptor interacting protein 1 (GRIP1), a seven-PDZ domain protein scaffold, regulates glutamate receptor surface expression and trafficking in neurons. We have found that human and mouse T cells also express GRIP1. T cell-specific GRIP1(-/-) mice >11 weeks old had prolonged cardiac allograft survival. Compared with wild-type T cells, in vitro stimulated GRIP1(-/-) T cells had decreased expression of activation markers and increased apoptotic surface marker expression. Surface expression of the strong T cell inhibitory molecule cytotoxic T lymphocyte antigen-4 (CTLA-4) was increased on GRIP1(-/-) T cells from mice >11 weeks old. CTLA-4 increases with T cell stimulation and its surface expression on GRIP1(-/-) T cells remained high after stimulation was removed, indicating a possible internalization defect in GRIP1-deficient T cells. CTLA-4-blocking antibody treatment following heart transplantation led to complete rejection in T cell GRIP1(-/-) mice, indicating that increased CTLA-4 surface expression contributed to the extended graft survival. Our data indicate that GRIP1 regulates T cell activation by regulating CTLA-4 surface expression.

Abstract
Abstract
Background: The heterogeneous nature of the mucinous breast cancer (MBC), with its subtypes of pure (PMBC) and mixed carcinoma (MMBC), calls for more precise individualized prognosis assessment. PMBC showed favorable prognosis in both Chinese and Caucasian women, with nodal status and TNM stage as the prognostic predictors [PMID: 18026874, 22451233]. However, few studies had investigated tumor biology and prognosis of MMBC in Chinese population, especially with respect to the different co-existing cancer components.
Methods: From January 1983 to December 2014, 197 consecutive MBC patients, including 117 PMBC and 80 MMBC, received breast cancer surgery in Peking Union Medical College Hospital. The clinicopathological characteristics, treatment choice, disease-free survival (DFS) and overall survival (OS) were compared both between PMBC vs MMBC, and among subgroups of MMBC according to the mixed entities, including 24 women with ductal caricinoma in situ (DCIS) and 45 with IDC. Univariate and Cox multivariate analyses were performed to identify the prognostic factors.
Results: The 197 MBC comprised 1.9% of contemporary 10,192 breast cancer (BC). Compared to PMBC, MMBC had significantly more lymph node metastasis (p=0.038), Her2 positivity (p=0.036), high Ki-67 index (defined as >20%, p=0.026) and anti-Her2 targeted therapy (p=0.006). All these differences remained significant when the comparison were performed among PMBC, MBC+DCIS and MBC+IDC, and additional significant difference were identified in tumor size (p=0.036), pTNM stage (p=0.003) and chemotherapy (p=0.003). However, no significant difference was found in DFS or OS between any two subtypes/subgroups of MBC, including PMBC, MMBC, MBC+DCIS and MBC+IDC.
Table 1. Comparison of survival outcomes among PMBC, MBC+DCIS and MBC+IDC§SurvivalPMBC (N=117, Median, range, and Mean±SD)MBC+DCIS (N=24, Median, range, and Mean±SD)MBC+IDC (N=45, Median, range, and Mean±SD)P-ValueDFS (months)43 (1-233), 52.7±45.227 (1-84), 34.3±25.326 (1-113), 33.1±26.60.187OS (months)46 (1-312), 56.9±51.827 (1-84), 34.4±25.326 (1-113), 34.8±28.70.628§ Kaplan-Meier survival curves would be displayed in the poster
High Ki-67 index (p=0.046) appeared to be the significant DFS related prognostic factor for PMBC, whereas estrogen receptor (ER) status (univariate p=0.000, multivariate p=0.062) and immunophenotype (luminal, her2, or triple-negative, univariate p=0.000, multivariate p=0.079) might be the potential DFS predictors for MMBC. None of the above-mentioned clinicopathological factors could serve as OS predictors for MBC.
Conclusion: This population-based study showed that there were significant difference in nodal status, Ki-67, Her2 positivity and targeted therapy between PMBC and MMBC, and furthermore in tumor size, stage and chemotherapy among PMBC and subgroups of MMBC such as MBC+DCIS and MBC+IDC. However, survival outcomes were similar between these clinical entities and subgroups, suggesting the intra-tumoral heterogeneity might not interfere with survival outcomes of MBC in Chinese woman. High Ki-67 index was identified as the significant DFS related prognostic factor for PMBC, whereas ER status and immunophenotype as the potential DFS predictors for MMBC.

Abstract
OBJECTIVES This study investigated the influence of root variations on the root surface area (RSA) by using micro-CT scans. DESIGN A total of 228 extracted permanent teeth (2-rooted and single-rooted maxillary first premolars, mandibular first premolars with non-Tomes' and Tomes' roots, 2-rooted and 3-rooted mandibular first molars, and 2-rooted and C-shaped mandibular second molars) were collected in a Chinese population and scanned using a micro-CT. In Mimics 15.01, 3D tooth models were generated, and the net and percent remaining RSA at various simulated attachment levels were measured. The data corresponding to attachment level were fitted to a linear function. RESULTS The mean total RSA for different root forms decreased in the following order: 3-rooted>2-rooted>C-shaped>single-rooted. However, the differences were statistically significant (p<0.01) only for 2-rooted vs. single-rooted maxillary first premolars, and 2-rooted vs. C-shaped mandibular second molars. Linear functions can perfectly fit in relating the attachment level to the net and percent remaining RSA. CONCLUSION Micro-CT combined with Mimics software offers simple and precise technique for quantitative analysis of the RSA. Root variations may affect the total amount and vertical distribution of the net RSA. However, the degree of influence varies with the tooth type.

Abstract
Artificial illumination is an important exogenous factor in the control of many physiological and behavioral processes as well as an important environmental factor in the management of laying hens. Melatonin receptors are members of the G protein-coupled receptor family. The hormone melatonin is secreted primarily by the pineal gland, with highest levels occurring during the dark period of a circadian cycle. The aim of this study was to examine the effect of monochromatic light on chicken egg reproduction and expression of melatonin receptors in chicken ovarian follicles. A total of 552 19-week-old hens were randomly divided into 4 groups with 138 birds in each group. Each group was randomly divided into 3 replicates with 46 birds in each replicate. Feed and water were provided for ad libitum. Light treatments were: control cool white (400-760 nm), blue (480 nm), green (560 nm), and red (660 nm). The short wavelength (blue light) group produced a greater total number of eggs at 300 days of age than did the long wavelength (red light) group, and the red light group showed higher melatonin receptor type 1A and melatonin receptor type 1C mRNA and protein expression. These results suggest that the wavelength of light is closely related to chicken egg number at 300 days of age; there is no effect of monochromatic light on melatonin receptor type 1B.

Abstract
The objective of this study was to investigate the effects of sex and slaughter age of chickens on fatty acid composition and TBC1D1 gene expression in 4 different tissues: breast muscle, thigh muscle, abdominal fat, and subcutaneous fat. Sixty Erlang mountainous chickens (hybrid SD02 x SD03) were raised under the same conditions and slaughtered at 8, 10, and 13 weeks of age. The results showed that the sex of the animal significantly affected the content of arachidic acid (C20:0), sinapic (C22:1), linoleic (C18:2n-6), eicosapentaenoic (C20:5n-3), and docosahexaenoic acids (C22:6n-3), whereas other fatty acid contents were not affected. Age had a significant effect on most monounsaturated fatty acids, except for octadecenoic acid (C18:1). TBC1D1 mRNA was abundant in all tissues at all 3 ages of slaughter. Cocks exhibited higher TBC1D1 mRNA levels than hens in the thigh muscle and abdominal fat at 10 and 13 weeks, respectively.

Abstract
The potential of using corn steep liquor powder (CSLP), peanut meal (PM), soybean meal (SM), cotton meal (CM) and urea as the substitute of yeast extract (YE) as the nitrogen source was investigated for producing succinic acid (SA). Actinobacillus succinogenes GXAS137 was used as the fermenting bacterium and sugarcane molasses was used as the main substrate. None of these materials were able to produce SA as high as YE did. The CSLP could still be considered as a feasible and inexpensive alternate for YE as the yield of SA produced using CSLP was second only to the yield of SA obtained by YE. The use of CSLP-PM mixed formulation (CSLP to PM ratio = 2·6) as nitrogen source produced SA up to 59·2 g l(-1) with a productivity of 1·2 g l(-1) h(-1). A batch fermentation using a stirred bioreactor produced up to 60·7 g l(-1) of SA at the same formulation. Fed-batch fermentation that minimized the substrate inhibition produced 64·7 g l(-1) SA. These results suggest that sugarcane molasses supplemented with a mixture of CSLP and PM as the nitrogen source could be used to produce SA more economically using A. succinogenes. Significance and impact of the study: Succinic acid (SA) is commonly used as a platform chemical to produce a number of high value derivatives. Yeast extract (YE) is used as a nitrogen source to produce SA. The high cost of YE is currently the limiting factor for industrial production of SA. This study reports the use of a mixture of corn steep liquor powder (CSLP) and peanut meal (PM) as an inexpensive nitrogen source to substitute YE. The results showed that this CSLP-PM mixed formulation can be used as an effective and economic nitrogen source for the production of SA.

Abstract
Coccidiosis is a major intestinal disease of poultry, caused by several species of the protozoan Eimeria. The objective of this study was to examine changes in expression of digestive enzymes, nutrient transporters, and an antimicrobial peptide following an Eimeria praecox challenge of chickens at days 3 and 6 post-infection. Gene expression was determined by real-time PCR and analyzed by one-way ANOVA. In the duodenum, the primary site of E. praecox infection, a number of genes were downregulated at both d3 and d6 post-infection. These genes included liver expressed antimicrobial peptide 2 (LEAP2), the cationic (CAT1), anionic (EAAT3), and L-type (LAT1) amino acid transporters, the peptide transporter PepT1 and the zinc transporter ZnT1. Other transporters were downregulated either at d3 or d6. At both d3 and d6, there was downregulation of B(o)AT and CAT1 in the jejunum and downregulation of LEAP2 and LAT1 in the ileum. LEAP2, EAAT3, and ZnT1 have been found to be downregulated following challenge with other Eimeria species, suggesting a common cellular response to Eimeria.

Abstract
OBJECTIVE Few data is available on the nutritional status of old Chinese. The present study aimed to describe the nutritional status and clinical correlates for malnutrition risk in the older people. DESIGN Cross-sectional study. SETTING Hospital- and community-based older people were recruited in the region of Chongqing, China. PARTICIPANTS 558 individuals aged 60 years old or over between April 2011 and October 2012. MEASUREMENTS Comprehensive geriatric assessment was performed and nutritional status was assessed by the Mini Nutritional Assessment Short Form (MNA-SF). Nutrition-associated factors were analyzed, including health status (chronic diseases, depression, cognition, function impaired), social factors (education status, marital status, the type of work before 60 years old) and life style factors (smoking, drinking, diet). RESULTS The mean age was 73.1±8.0 years and 43.9% were men. Prevalence of malnutrition and risk for malnutrition were 3.2% and 19.3 %, respectively. Several factors increased poor nutrition independently including self-rated health, comorbidity, chronic obstructive pulmonary disease, gastrointestinal disease and cognitive impairment. Fish decreased the risk of poor nutrition. CONCLUSIONS The prevalence was relatively low in older people of Chongqing, Southwest China. Poor nutrition was found to be increased due to the common health problems. Thus the patients with these problems should pay more attention on nutritional status. The older people should often have fish because of their nutritional benefit.

Abstract
Signal transducers and activators of transcription (STAT) play critical roles in development, proliferation, and immune defense. However the consequences of STAT hyperactivity can predispose to diseases, including colorectal cancer. In the present study, we aimed to evaluate the function of STAT4 in human colorectal cancer (CRC). The expression of STAT4 was examined by immunohistochemical assay using a tissue microarray procedure. A loss-of-function experiment was carried out to investigate the effects of lentivirus-mediated STAT4 shRNA (Lv-shSTAT4) on cell proliferation and invasive potential indicated by MTT and Transwell assays in CRC cell lines (SW480 and Caco2). As a consequence, it was found that the expression of STAT4 protein was significantly increased in CRC tissues compared with that in adjacent non-cancerous tissues (ANCT) (71.1% vs 44.4%, P=0.015), and was related with the Dukes staging and depth of invasion in CRC patients (P=0.022; P=0.001). Silencing of STAT4 gene suppressed cell proliferation and invasion of CRC cells. Taken together, these findings demonstrate that increased expression of STAT4 is positively correlated with the depth of invasion in CRC patients, and inhibition of STAT4 expression represses the growth and invasion of CRC cells, suggesting that STAT4 may be a promising therapeutic target for the treatment of CRC.

Abstract
DNA polymerase eta (Polη) plays unique and pivotal functions in several DNA damage-tolerance pathways. Steady-state level of this short-lived protein is tightly controlled by multiple mechanisms including proteolysis. Here, we have identified the deubiquitinating enzyme, ubiquitin-specific protease 7 (USP7), as a novel regulator of Polη stability. USP7 regulates Polη stability through both indirect and direct mechanisms. Knockout of USP7 increased the steady-state level of Polη and slowed down the turnover of both Polη and p53 proteins through destabilizing their E3 ligase Mdm2. Also, USP7 physically binds Polη in vitro and in vivo. Overexpression of wild-type USP7 but not its catalytically-defective mutants deubiquitinates Polη and increases its cellular steady-state level. Thus, USP7 directly serves as a specific deubiquitinating enzyme for Polη. Furthermore, ectopic expression of USP7 promoted the UV-induced PCNA monoubiquitination in Polη-proficient but not Polη-deficient XPV cells, suggesting that USP7 facilitates UV-induced PCNA monoubiquitination by stabilizing Polη. Taken together, our findings reveal a modulatory role of USP7 in PCNA ubiquitination-mediated stress-tolerance pathways by fine-tuning Polη turnover.

Abstract
OBJECTIVE Dopamine receptor (DR) signaling is involved in the pathogenesis of autoimmune diseases. We aimed to measure the expression levels of DR1-5 on B cells from patients with rheumatoid arthritis (RA) and to analyze the relationship between DRs and clinical manifestations, inflammatory biomarkers, functional status and disease activity. METHODS A total of 29 patients with RA, 12 healthy donors and 12 patients with osteoarthritis (OA) were recruited in this study. Flow cytometry was used to measure the levels of DR1-5 expressed on B cells. The relationships between B cell DR expressions and clinical features in RA patients were analyzed using the Spearman correlation test. RESULTS The expression levels of B cell DR1-5 in both the RA and OA groups were lower than those in healthy controls. After 3 months of medication, all five receptors were elevated in RA patients, with DR2 and DR3 being significantly increased from the baseline. DR2 expression on B cells was negatively correlated with inflammatory biomarkers and disease activity. CONCLUSION RA patients had lower expression level of DR2 on B cells compared to the healthy controls, and the level of DR2 negatively correlated with the disease activity. DR2 and DR3 might be novel predictors of patient responses to disease modifying antirheumatic drug therapy.

Abstract
WHAT IS KNOWN AND OBJECTIVE Rituximab is a chimeric anti-CD20 IgG1 monoclonal antibody for the treatment of various forms of lymphoma and haematological autoimmune diseases. Interstitial lung disease is a rare but lethal pulmonary toxicity of rituximab. Nod-like receptor pyrin domain-containing protein 3 (NLRP3) inflammasome is a molecular platform activated upon signs of cellular 'danger' to trigger the maturation of pro-inflammatory cytokines. We report the first case of rituximab-induced interstitial lung disease (R-ILD) with NLRP3 inflammasome activation in the lung. CASE SUMMARY A 30-year-old male patient diagnosed with idiopathic thrombocytopenic purpura (ITP) was treated with four cycles of rituximab in one month. Three weeks after last rituximab administration, he developed progressive dyspnoea associated with respiratory failure, which was diagnosed as R-ILD. The patient showed a good response to steroid treatment, and lung biopsy was performed 5 days after the treatment. Immunohistopathological studies of lung specimens showed high expressions of inflammasome components NLRP3, apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) and caspase-1 in lung interstitium with a heavy infiltration of CD19-positive cells. The levels of inflammasome-related cytokines IL-1β and IL-18 in the serum were declined during the therapy. WHAT IS NEW AND CONCLUSIONS This is the first report confirmed the role of NLRP3 inflammasome in pulmonary toxicity of rituximab. Inhibited activation of NLRP3 inflammasome in lung by steroid treatment could reverse R-ILD and block subsequent lung fibrosis. This result could open a new sight into the pathogenesis and provide a new target for the treatment of R-ILD.

Abstract
Native chickens hold a significant share of the market in China. In response to the huge demand from the market, the productivity of Chinese native chickens needs to be improved. Cross breeding is an effective method to increase productivity, although it might affect meat quality. In this study, two pure lines (SD02 and SD03) of Erlang mountainous chickens were hybridized with a yellow feather and faster growing line (SD01). The effect of hybridization on carcass and meat quality (physiochemical and textural traits) was measured in the F1 population at d 91 of age. The hybrids exhibited higher body weight and dressed weight, and amount of semi-eviscerated, eviscerated, breast muscle and abdominal fat (p<0.05). Abdominal fat yield also increased (p<0.05) compared to the offspring of the two pure-lines. Meanwhile, there was no significant difference in meat quality traits except for the myofiber diameter and density and the shear force of the breast muscle. Overall, the offspring of cross-lines were similar to pure lines in meat color, pH value, inosinic acid, crude protein, crude fat, dry matter, moisture content and amino acid composition in the breast muscle. These results suggest that productivity can be improved via cross-breeding while maintaining meat quality of the Erlang mountainous chicken.

Abstract
Genetic causes account for more than half of congenital hearing loss cases. The most frequent mutations found in non-syndromic hearing loss patients occur in GJB2 and SLC26A4. Mitochondrial genome mutations are also prevalent. However, the frequency of common hearing loss mutations in the Chinese population has not yet been well estimated. Here, we implemented the SNaPshot genotyping method to investigate the carrier frequency of 15 commonly reported hearing loss mutations in GJB2, SLC26A4 and the mitochondrial genome based on a cohort of 5800 neonates in China. Up to 15.9% (923/5800) of the newborns carry at least one mutant allele. The top three were GJB2-c.109G>A, GJB2-c.235delC, and SLC26A4-c.919A>G, with notably high carrier frequencies of 1/10, 1/53 and 1/62 respectively, and mt-7444G>A with 1/141 was the most frequent allele in the mitochondrial genome. In this cohort, 0.48% (28/5800) of neonates were genetically diagnosed with hearing loss, from which seven cases failed an OAE test. This is the first epidemiological study of non-syndromic hearing loss in Chinese newborns indicating a notably high carrier frequency (1 per 6.3 newborns) among these 15 mutant alleles. Our carrier frequency data also aid in effective risk assessment and genetic counseling for hearing loss patients in the Chinese population.

Abstract
BACKGROUND Polymorphism of rs2293855 in gene MTMR9 has been associated with obesity and metabolic syndrome. We aim to study the association of rs2293855 with type 2 diabetes mellitus (T2DM) intermediate phenotypes in a Han Chinese population. METHODS The polymorphism was genotyped in 838 Han Chinese individuals using Matrix-Assisted Laser Desorption/Ionization Time of Flight Mass Spectrometry (MALDI-TOF MS); all participants underwent a 75 g oral glucose tolerance test (OGTT); associations between the polymorphism and glucose tolerance, indices of insulin secretion and indices of insulin sensitivity were analyzed. RESULTS The frequency of genotypes and alleles differed significantly between normal glucose tolerance and prediabetes (P=0.043 and P=0.009, respectively). The GG homozygous presented higher fasting plasma glucose (P=0.009), higher 2-hour plasma glucose (P=0.024) and higher glucose area under the curve (AUC, P=0.01). Moreover, the G allele of rs2293855 was associated with glucose intolerance (fasting glucose, P=0.012; glucose AUC, P=0.006; 2-h glucose, P=0.024); it is also associated with decreased indices of insulin sensitivity (fasting insulin, P=0.043; insulin sensitivity index composite, P=0.009; homeostasis model assessment of insulin resistance, HOMA-IR, P=0.008) and decreased indices of insulin secretion (HOMA of beta cell function, HOMA-B, P=0.028; insulinogenic index, P=0.003). In addition, the minor allele G was also associated with increased risk of prediabetes (OR=1.463, 95%CI: 1.066-2.009, P=0.018). CONCLUSIONS Polymorphism of rs2293855 in MTMR9 is associated with measures of glucose tolerance, indices of insulin secretion and indices of insulin sensitivity. We also suggest that allele G is likely to increase the risk of prediabetes by influencing both insulin secretion and insulin sensitivity.

Abstract
Cellular retinol-binding protein II (CRBP II) belongs to the family of cellular retinol-binding proteins and plays a major role in absorption, transport, and metabolism of vitamin A. In addition, because vitamin A is correlated with reproductive performance, we measured CRBP II mRNA abundance in erlang mountainous chickens by real-time PCR using the relative quantification method. The expression of CRBP II showed a tissue-specific pattern and egg production rate-dependent changes. The expression was very high (p<0.05) in jejunum and liver, intermediate in kidney, ovary, and oviduct, and lowest (p<0.05) in heart, hypothalamus, and pituitary. In the hypothalamus, oviduct, ovary, and pituitary, CRBP II mRNA abundance were correlated to egg production rate, which increased from 12 wk to 32 wk, peaked at 32 wk relative to the other time points, and then decreased from 32 wk to 45 wk. In contrast, the expression of CRBP II mRNA in heart, jejunum, kidney, and liver was not different at any of the ages evaluated in this study. These data may help to understand the genetic basis of vitamin A metabolism, and suggest that CRBP II may be a candidate gene to affect egg production traits in chickens.

Abstract
Abstract
Purpose: In previous studies, the utilization of ultrasound guided near infrared diffused light imaging (US-NIR) has shown great potential in predicting and monitoring the pathologic tumor response to neoadjuvant chemotherapy (NAC). The purpose of the current study is to develop a prediction model utilizing pretreatment tumor hemoglobin content measured by US-NIR in conjunction with standard pathologic tumor characteristics to predict pathologic response even before NAC is given. Utilizing a multiple logistic regression model, the sensitivity, specificity, positive and negative predictive values (PPV and NPV), and the area under the receiver operating characteristic curve (AUC) are determined for the models.
Materials and Methods: 34 patients’ data were retrospectively analyzed using a multiple logistic regression model to predict response. These patients were split into a training group (23 patients of 24 tumors) and testing group (11 patients of 12 tumors). Tumor vascularity was assessed pre-NAC using US-NIR and measurements of total hemoglobin (tHb), oxygenated (oxyHb), and deoxygenated hemoglobin concentrations (deoxyHb) as well as tumor reduced scatter coefficients acquired before treatment. Tumor pathologic variables including the estrogen (ER) and progesterone (PR) receptors, human epidermal growth factor receptor 2 (HER2) and Nottingham score (mitotic index and grade) were acquired before NAC in biopsy specimens and were also used in the prediction model. The patients’ pathologic response was graded based on the Miller-Payne system as non- and partial-responders (grades 1-3) and near-complete and complete responders (grades 4-5).
Results: Utilizing initial tumor pathologic characteristics (grade and receptor status) a sensitivity of 100%, specificity of 73.3%, PPV and NPV of 69.5% and 100%, and AUC of 0.83(95% CI: 0.637-963) were obtained from training data. When pretreatment hemoglobin parameters and reduced scatter coefficients were included as additional predictors in training data, sensitivity, specificity, PPV and NPV improved to 100% and AUC of 1.0 (95% CI: 1.0-1.0). The performance of the predictive models were validated on testing data and corresponding values were 100%, 66.7%, 75.0% and 100%, and AUC of 0.83 (CI: 0.56-1.0) when tumor pathologic parameters alone were used as predictors. While the corresponding values were 100% and AUC of 1.0 (CI: 1.0-1.0) when hemoglobin and reduced scatter parameters were added as predictors.
Discussion: These initial findings indicate that combining widely used tumor pathologic variables with hemoglobin and optical scatter functional parameters determined by NIR provides a powerful tool for predicting patient response to preoperative chemotherapy before the initiation of the treatment. With the current trend to treat in the neoadjuvant setting, such a tool will be invaluable for response assessment. Plans are underway to validate this model in larger patient settings and its applicability to non-chemotherapeutic regimens.

Multiple variants associated with hypertension have been identified in the large numbers of genome-wide association studies, meta-analysis, and case-control studies. The present study investigated the association between the single nucleotide polymorphisms (SNPs) of five candidate genes and the susceptibility and prognosis of hypertension in a Chinese Han population. A hospital-based case-control study in a Chinese Han population was carried out, including 500 hypertension patients and 506 healthy controls. The five SNP markers were detected using the Sequenom MassArray(®) iPLEX System. The association of genotypes with susceptibility to hypertension was analyzed using odds ratio, with 95% confidence interval and logistic regression. All five variants conformed to Hardy-Weinberg proportions in the controls. No significant differences were noted in the genotype distributions for AGTR1, PRRC2A, and CALCA polymorphisms in patients with hypertension (N = 500) and healthy controls (N = 506). SNP rs2932538, a variant in MOV10, was found to be significantly associated with an increased risk of hypertension. However, SNP rs4373814, a variant in CACNB2, showed a relevant association with a decreased risk of hypertension. In conclusion, the results of our case-control study confirmed the significant association of the SNP rs2932538 in MOV10 and SNP rs4373814 in CACNB2 with an increased risk of hypertension in a Chinese Han population, suggesting that the SNP rs2932538 may be a poor prognostic indicator for hypertension, while SNP rs4373814 may be a good prognostic indicator for hypertension in the same region. However, our findings need to be replicated in larger epidemiological and functional studies.

Abstract
BACKGROUND MicroRNAs (miRNAs) are small non-coding RNAs that regulate physiological and pathological processes by suppressing target gene expression. Altered expression of miR-30a-3p has been demonstrated in several cancers. However, little about how miR-30a-3p functions in these cancers has been reported, and the role of miR-30a-3p in hepatocellular carcinoma (HCC) is unknown. The purpose of this study was to identify the role and underlying molecular mechanism of action of miR-30a-3p in HCC. METHODS A total of 110 HCC patients, primarily treated by surgical removal of tumors, were involved in the study. HCC cell line Bel-7402 was selected to characterize the function of miR-30a-3p in vitro. RESULTS Our results showed that in 83.6% of the 110 HCC patients, expression of miR-30a-3p was significantly downregulated (P < 0.0001) in tumors compared to adjacent normal tissues. In a clinicopathological correlation analysis, downregulation of miR-30a-3p correlated with a significantly higher incidence of portal vein tumor thrombus (PVTT, P = 0.009). Moreover, miR-30a-3p markedly inhibited the invasion and migration of Bel-7402 HCC cells in vitro. Furthermore, miR-30a-3p overexpression had an inhibitory effect on cell proliferation, induced apoptosis and increased arrest of cells in the S phase. We further demonstrated that miR-30a-3p regulates HCC cell function by a mechanism involving reduced vimentin and MMP3 expression and restoration of E-cadherin expression. CONCLUSIONS our data suggest that miR-30a-3p is downregulated in HCC and acts as a tumor suppressor in vitro. Regulation of vimentin, E-cadherin and MMP3 by miR-30a-3p suggests a useful therapeutic strategy for tumors with reduced miR-30a-3p expression.

Abstract
OBJECTIVE The aim of this study was to determine the correlation between human adrenocortical carcinoma and the proteins involved in tumor angiogenesis, and to evaluate the angiogenic status of adrenocortical carcinoma. METHODS The expression of signal transducer and activator of transcription 3 and insulin-like growth factor 2 as well as microvessel density was measured in a series of tissue samples from 44 human sporadic adrenocortical tumors by immunohistochemistry. These specimens were classified as adenomas (n = 20) and carcinomas (n = 24) according to the histological criteria defined by Weiss. RESULTS A total of 19 of 24 (79.17 %) malignant cases showed positive staining for signal transducer and activator of transcription 3 and 4 of 20 (20.00 %) benign cases showed positive, the difference of signal transducer and activator of transcription 3 expression between adrenocortical adenomas and adrenocortical carcinomas was statistically significant (P < 0.001). Similarly, insulin-like growth factor 2 staining was seen in 70.83 % (17/24) of the malignant cases versus 25.00 % (5/20) of the benign, the difference of insulin-like growth factor 2 expression among two groups was statistically significant (P = 0.002). Malignant cases showed higher microvessel density compared to benign tumors (84.70 ± 12.44 vs 21.05 ± 8.07, P < 0.001). Signal transducer and activator of transcription 3 and insulin-like growth factor 2 expression were positively correlated with microvessel density in all specimens (r_s = 0.832, P < 0.001; r_s = 0.703, P = 0.001). CONCLUSIONS This study has confirmed that adrenocortical carcinoma overexpress signal transducer and activator of transcription 3 and insulin-like growth factor 2; these results suggest that angiogenesis of human adrenocortical carcinoma may be mediated by these proteins and they could represent selective targets for the molecularly targeted treatments of adrenocortical carcinoma.
