Abstract
In 1913, after the Russian Prostitutes Sanatorium of Harbin Eastern Railway was received by the board of directors, they established the "Harbin City Board Hospital" and funded its expansion. In March 1926, the provisional Committee of the Harbin autonomous renamed the "City Board of First Hospital" to "The Public Hospital" . In November 1926, "The Public Hospital" was renamed as "Harbin Special Municipal Hospital" by the Harbin City Council and further funds were invested in its construction. In 1931, the Japanese invaded Northeast China, and controlled the "City Hospital" . In 1946, when Harbin was liberated, after the Communist's take-over of the Hospital, it developed sustainedly since then. From 1946-1949, The First Hospital of Harbin City dispatched manpower, material resources, and financial resources to support the people's Liberation Army, establishedthe medical service team, received and treated the wounded. From the 1930s, the Hospital was involved in the treatment of cholera, plague, scarlet fever, typhus and other infectious diseases, and participated in the medical rescue in Wenchuan of Sichuan and Xinjiang Aletai area. From 1928, the Hospital took over from Binjiang Hospital as the Teaching Hospital of Harbin Medical School, and later became the Harbin Medical University Teaching Hospital. It made contribution to the training of medical students.

Abstract
Essentials Vitronectin (VN) is produced by smooth muscle cells (SMCs) and promotes neointima formation. We studied the regulation of vascular VN expression by plasminogen activator inhibitor-1 (PAI-1). PAI-1 stimulates VN gene expression in SMCs by binding LDL receptor-related protein 1. Stimulation of VN gene expression may be a mechanism by which PAI-1 controls vascular remodeling. SUMMARY Background Increased expression of vitronectin (VN) by smooth muscle cells (SMCs) promotes neointima formation after vascular injury, and may contribute to chronic vascular diseases, such as atherosclerosis. However, the molecular regulation of vascular VN expression is poorly defined. Given the overlapping expression profiles and functions of VN and plasminogen activator inhibitor (PAI)-1, we hypothesized that PAI-1 regulates vascular VN expression. Objectives To determine whether PAI-1 regulates VN expression in SMCs and in vivo. Methods The effects of genetic alterations in PAI-1 expression, pharmacologic PAI-1 inhibition and recombinant PAI-1 on SMC VN expression were studied, and vascular VN expression in wild-type (WT) and PAI-1-deficient mice was assessed. Results VN expression was significantly lower in PAI-1-deficient SMCs and significantly increased in PAI-1-overexpressing SMCs. PAI-1 small interfering RNA and pharmacologic PAI-1 inhibition significantly decreased SMC VN expression. Recombinant PAI-1 stimulated VN expression by binding LDL receptor-related protein-1 (LRP1), but another LRP1 ligand, α2 -macroglobulin, did not. As compared with WT controls, carotid artery VN expression was significantly lower in PAI-1-deficient mice and significantly higher in PAI-1-transgenic mice. In a vein graft (VG) model of intimal hyperplasia, VN expression was significantly attenuated in PAI-1-deficient VGs as compared with WT controls. The plasma VN concentration was significantly decreased in PAI-1-deficient mice versus WT controls at 4 weeks, but not at 5 days or 8 weeks, after surgery. Conclusions PAI-1 stimulates SMC VN expression by binding LRP1, and controls vascular VN expression in vivo. Autocrine regulation of vascular VN expression by PAI-1 may play important roles in vascular homeostasis and pathologic vascular remodeling.

Abstract
Objective: To investigate the significance of monitoring the gradients between transcutaneous PCO(2) and end-tidal PCO(2) [P(c-et)CO(2)] in patients with septic shock. Method: Thirty-five mechanically ventilated patients with early septic shock were enrolled as the study group and 18 non-septic shock patients with stable hemodynamics as the control group between May 2014 and October 2016. The patients with septic shock were treated by early goal-directed therapy (EGDT) within 6 hours since hospitalization. The differences of baseline level of P(c-et)CO(2) and arterial lactate concentration (LAC) between the two groups and the variations of these indexes after EGDT in the study group were compared respectively. Results: The baseline levels of P(c-et)CO(2) and LAC in patients with septic shock were significantly higher than those of the control group [(26.0±16.2) mmHg vs (11.0±5.6) mmHg (1 mmHg=0.133 kPa) and (4.0±1.7) mmol/L vs (1.6±0.6)mmol/L, all P=0.000]. The area under receiver operator characteristic (ROC) curve (AUC) for baseline P(c-et)CO(2) and LAC was 0.924 (95%CI: 0.851-0.996) and 0.931 (95%CI: 0.872-1.000), respectively. P(c-et)CO(2) >12.6 mmHg and LAC >2.5 mmol/L could discriminate septic shock patients from those without shock with the same sensibility of 97% and the specificity of 83% and 78% respectively. With regard to the prognosis (Day 28) of the patients with septic shock, AUC for baseline P(c-et)CO(2) and LAC was 0.709 (95%CI: 0.533-0.886) and 0.714 (95%CI: 0.545-0.883), respectively. P(c-et)CO(2) >20.0 mmHg and LAC>3.6 mmol/L could discriminate survivors from non-survivors with the same sensibility of 92% and the same specificity of 76%. All the patients in the study group completed EGDT within 6 hours after admission, 20 (57.1%) passed EGDT and 17 (85.0%) survived, 15 (42.9%) failed EGDT and 4 (26.7%) survived, and the survival rates were significantly different (F=9.844, P=0.001). After EGDT, P(c-et)CO(2) (21.0±9.5 mmHg) and LAC(3.3±2.5 mmol/L)reduced significantly compared with the baselines (P=0.008 and P=0.046), and the associated AUC was 0.905(95%CI: 0.792-1.000) and 0.747 (95%CI: 0.576-0.917)respectively. P(c-et)CO(2) > 16.5 mmHg and LAC > 3.1 mmol/L could discriminate survivors from non-survivors with the sensibility of 97% and 91%, and the specificity of 78% and 69%, respectively. Conclusions: P(c-et)CO(2) >12.6 mmHg could play the same role as LAC in recognizing early septic shock. EGDT was an effective therapy for the septic shock and P(c-et)CO(2) reflected efficacy. P(c-et)CO(2)>20 mmHg before EGDT and >16.5 mmHg after EGDT both could predict the 28 d prognosis of patients with septic shock, and the effect of the former was equal to that of LAC, but the latter was better than LAC.

Abstract
Objective: To investigate the relationship between serum uric acid (SUA) levels and high sensitive C-reactive protein (hs-CRP) in patients with type 2 diabetes mellitus (T2DM). Methods: A total of 400 patients who were hospitalized in the Department of Endocrinology and Metabolism of Jinshan Branch, Shanghai Sixth People's Hospital between April 2014 and December 2015 were divided into normouricemia (NUA, n=319) group and hyperuricemia (HUA, n=81) group according to the presence of HUA. Clinical features of the two groups were compared. Patients were further stratified into quartiles based on SUA levels, and then association between hs-CRP and SUA was analyzed. Results: Compared to the NUA group, the patients with HUA had higher hs-CRP concentration [2.12 (1.15, 6.73) mg/L vs 1.14 (0.52, 3.44) mg/L, P<0.001], erythrocyte sedimentation rate (ESR) [19.0 (10.5, 29.5) mm/h vs 12.0 (8.0, 17.0) mm/h, P<0.001], body mass index (BMI) [(25.2±3.6) kg/m(2) vs (23.6±3.6) kg/m(2,) P<0.001], and homeostasis model assessment-2 of insulin resistance (HOMA2-IR) index [1.88 (1.11, 2.94) vs 1.27 (0.77, 2.00), P<0.001]. After adjusting for age, the median level of hs-CRP of female with HUA was higher than that of male, female with NUA, and male with NUA (2.59, 1.94, 1.25 and 1.09 mg/L, respectively, P<0.001). There was significant difference in the prevalence of HUA among the patients with underweight, normal weight, overweight, and obesity (0, 12.3%, 21.6% and 25.8%, respectively, P=0.002). After adjusting for age and gender, duration of diabetes, BMI, serum lipids, level of SUA was still correlated with hs-CRP, HOMA2-IR, fasting C-peptide, blood urea nitrogen, serum creatinine, Cystatin C, microalbuminuria, respectively(all P<0.05). The level of SUA was positively associated with the increase of hs-CRP level (P=0.001). Multiple linear regression analysis showed that there was an independent and positive association between SUA and hs-CRP levels. Conclusion: SUA was independently associated with hs-CRP in T2DM patients, which suggested that chronic inflammation exists in HUA patients.

Abstract
Objective: To analyze the influence of growing experience on non-heterosexual orientation among male college students. Methods: From October to November in 2015, a total of 2 535 male students from 96 classes in 14 colleges/departments were recruited from two colleges that participated in the experimental work of AIDS prevention by cluster random sampling method. A structured questionnaire was administered in this study, including general demographic information, growing experience and Kinsey scale (to evaluate sexual orientation). Out of 2 500 questionnaires distributed in this study, 2 332 effective copies were withdrew, with the effective rate at 93.3%. Chi square test was used to analyze the differences of non-heterosexual orientation among the individuals with different social demographic characteristics. Multivariate logistic regression model was used to analyze the influencing factors of non-heterosexual orientation. Results: Among the 2 332 individuals, the proportion of self-reported non-heterosexual was 6.2% (144).The proportions of male students who identify as non-heterosexual from freshman to junior year were 5.2%(63/1216),6.9%(65/941),11.7%(13/111) and 4.7%(3/64), respectively (χ(2)=9.06,P=0.029). Compared with the individuals of very good relationship with parents, those with bad relationship (OR=3.3, 95%CI: 1.7-6.5) and general relationship (OR=1.7, 95%CI: 1.0-2.9) with parents had a higher risk of non-heterosexual orientation, respectively. Those encountered sexual assault had a higher risk of non-heterosexual orientation than those without encountered sexual assault (OR=5.9, 95%CI: 3.2-10.9). Conclusions: This study reported a high proportion of self-reported non-heterosexual among college male students in Nanjing, and highlighted the importance of targeting students with poor parental relationships and who subjected to sexually abused.

Abstract
Essentials New strategies are needed to inhibit thrombosis and intimal hyperplasia (IH) in vein grafts (VG). We studied effects of apyrase (APT102) on VGs and smooth muscle and endothelial cells (SMC/EC). APT102 inhibited thrombosis, SMC migration, and IH without impairing hemostasis or EC recovery. Apyrase APT102 is a single-drug approach to inhibit multiple processes that cause VG failure. SUMMARY Background Occlusion of vein grafts (VGs) after bypass surgery, owing to thrombosis and intimal hyperplasia (IH), is a major clinical problem. Apyrases are enzymes that scavenge extracellular ATP and ADP, and promote adenosine formation at sites of vascular injury, and hence have the potential to inhibit VG pathology. Objectives To examine the effects of recombinant soluble human apyrase, APT102, on platelets, smooth muscle cells (SMCs) and endothelial cells (ECs) in vitro, and on thrombosis and IH in murine VGs. Methods SMC and EC proliferation and migration were studied in vitro. Inferior vena cava segments from donor mice were grafted into carotid arteries of recipient mice. Results APT102 potently inhibited ADP-induced platelet aggregation and VG thrombosis, but it did not impair surgical hemostasis. APT102 did not directly inhibit SMC or EC proliferation, but significantly attenuated the effects of ATP on SMC and EC proliferation. APT102 significantly inhibited SMC migration, but did not inhibit EC migration, which may be mediated, at least in part, by inhibition of SMC, but not EC, migration by adenosine. At 4 weeks after surgery, there was significantly less IH in VGs of APT102-treated mice than in control VGs. APT102 significantly inhibited cell proliferation in VGs, but did not inhibit re-endothelialization. Conclusions Systemic administration of a recombinant human apyrase inhibits thrombosis and IH in VGs without increasing bleeding or compromising re-endothelialization. These results suggest that APT102 has the potential to become a novel, single-drug treatment strategy to prevent multiple pathologic processes that drive early adverse remodeling and occlusion of VGs.

Abstract
Abstract
Background: ONC201 is a small molecule originally identified as a TRAIL inducing compound (Allen et al., Sci. Trans. Med 2013). Two recent studies reported that ONC201 also induces an atypical stress response mediated in part by ATF4 and CHOP (Klein et al., Sci. Signal 2016 and Ishizawa et al., Sci. Signal 2016). ONC201 is currently being tested in phase1/2 clinical trials in multiple cancer types. In this study, we tested the effects of ONC201 on human breast cancer cells.
Methods: We tested ONC201 in 18 human breast cancer cell lines that represent ER+, HER2 amplified, TNBC basal A and TNBC basal B breast cancer. Cell death was analyzed by MTS assay after 5 days of treatment. Cells were treated with GST-TRAIL in parallel for comparison. Z-VAD-FMK was used as a pan-caspase inhibitor. To verify the mechanism of action of ONC201, siRNA against death receptors (DR) 4 and 5 were transfected to cells and tested in MTS assay and Western blotting. Seahorse XF analyzer and live cell imaging were used to further characterize the effect of ONC201.
Results: ONC201 reduced cell viability in breast cancer cell lines in all subtypes tested with IC50s ranging from 0.8-5 uM, similar to what has been reported for other cancer cell types. Unexpectedly, ONC201 did not induce caspase 3 or PARP cleavage, and its toxicity was not inhibited by Z-VAD-FMK, nor by siRNA knockdown of DR4 or DR5. By contrast GST-TRAIL induced caspase 3 and PARP cleavage and GST-TRAIL-induced cell death was inhibited by Z-VAD-FMK and by siRNA knockdown of DR5. Live cell imaging revealed ONC201 induces cell membrane ballooning followed by rupture, whereas GST-TRAIL induced classic apoptosis morphology. Together these results suggest that ONC201 kills breast cancer cells via a caspase-independent, DR4/5-independent mechanism distinct from TRAIL-induced apoptosis. Western blots revealed that ONC201 induces ATF4 and CHOP, consistent with the recently published observations. ONC201 also induced phosphorylation of AMP-dependent kinase (AMPK) in multiple breast cancer cell lines, suggesting that cellular ATP level is decreased by ONC201. ATP depletion by ONC201 was confirmed by direct measurement of cellular ATP. Seahorse XF analysis found that ONC201 inhibited mitochondrial oxygen consumption rate (OCR) but did not inhibit glycolysis as measured by the extracellular acidification rate. Long exposure to ONC201 significantly attenuated OCR, while acute treatment did not inhibit OCR. These data suggest that ONC201 inhibits mitochondrial oxidative phosphorylation via an indirect mechanism. Western blots demonstrated that ONC201 decreases expression of multiple mitochondrial proteins involved in oxidative phosphorylation. Both ONC201-induced toxicity and ATP depletion were enhanced when cells were cultured in non-glucose (galactose) medium. This is consistent with ONC201-induced inhibition of mitochondrial respiration. Supplementing glucose to cells grown in galactose medium partially rescued ONC201-dependent ATP depletion and cell death, and reversed ONC201-induced phospho-eIF2, ATF4 and CHOP induction.
Conclusion: Together, these data demonstrate that ONC201 can kill breast cancer cells by a novel mechanism involving inhibition of mitochondrial respiration.

Abstract
Regulation of crucial lncRNAs involved in differentiation of chicken embryonic stem cells (ESCs) to spermatogonia stem cells (SSCs) was explored by sequencing the transcriptome of ESCs, primordial germ cells (PGCs) and SSCs with RNA-Seq; analytical bioinformatic methods were used to excavate candidate lncRNAs. We detected expression of candidate lncRNAs in ESCs, PGCs and SSCs and forecasted related target genes. Utilizing wego, david and string, function and protein-protein interactions of target genes were analyzed. Finally, based on string analysis, interaction diagrams and relevant signaling pathways were established. Our results indicate a total of 9657 lncRNAs in ESCs, PGCs and SSCs, with 3549 defined as significantly different. We screened 20 candidate lncRNAs, each demonstrating a greater than eight-fold difference in |logFC| value between groups (ESCs vs. PGCs, ESCs vs. SSCs and PGCs vs. SSCs) or specifically expressed in an individual cell type. qRT-PCR results indicated that expression tendencies of candidate lncRNAs were consistent with RNA-Seq. Fifteen cis and four trans target genes were forecasted. Based on wego and string analyses, we found lnc-SSC1, lnc-SSC5, lnc-SSC2 and lnc-ESC2 negatively regulated target genes SUFU, EPHA3, KLF3, ARL3 and TRIM8, whereas SHH, NOTCH, TGF-β, cAMP/cGMP and JAK/STAT signaling pathways were promoted, causing differentiation of ESCs into SSCs. Our findings represent a preliminary unveiling of lncRNA-associated regulatory mechanisms during differentiation of chicken ESCs into SSCs, filling a research void in male germ cell differentiation related to lncRNA. Our results also provide basic information for improving in vitro induction systems for differentiation of chicken ESCs into SSCs.

Abstract
We hypothesized that single nucleotide polymorphisms (SNPs) in certain microRNAs contribute to congenital heart disease (CHD) phenotypes. Five hundred and seventy-three subjects were enrolled in this study. DNA extracted from peripheral blood cells was used for SNP genotyping of miR-196a2 (rs11614913), miR-27a (rs11671784, rs895819), and miR-499 (rs3746444). Allele and genotype association analyses were performed to evaluate the correlation between certain microRNA SNPs and three phenotypes of isolated CHD: atrial septal defect (ASD), ventricular septal defect (VSD), and patent ductus arteriosus (PDA). All the participants carried a homozygous CC variant of miR-27a (rs11671784). The homozygous CC variant of miR-196a2 (rs11614913, T>C) was negatively associated with ASD compared with the wild-type TT variant (OR = 0.379, 95%CI = 0.209-0.686, P = 0.001). The miR-196a2 C allele was negatively associated with ASD compared with the T allele (OR = 0.646, 95%CI = 0.491-0.849, P = 0.002). The statistically significant results were further confirmed by dominant and recessive model assays. SNPs of miR-27a (rs895819, T>C) and miR-499 (rs3746444, A>G) showed diverse association with ASD, VSD, or PDA, but the differences were not statistically significant. The rs11614913 (T>C) SNP of miR-196a2 is associated with ASD, and the homozygous CC variant and the C allele are protective factors associated with ASD. The homozygous CC variant and the C allele of the rs11614913 (T>C) SNP of miR-196a2 are associated with a significantly reduced risk of ASD.

Abstract
The retracted article is: Ji Y, Jin HH, Wang MD, Cao WX, et al. (2016). Methylation of the RASSFIA promoter in breast cancer. Genet. Mol. Res. 15: gmr.15028261. There are significant parts of this article (particularly, in the discussion section) that are copied from "Methylation of HIN-1, RASSF1A, RIL and CDH13 in breast cancer is associated with clinical characteristics, but only RASSF1A methylation is associated with outcome", by Jia Xu, Priya B Shetty, Weiwei Feng, Carol Chenault, Robert C Bast Jr, Jean-Pierre J Issa, Susan G Hilsenbeck and Yinhua Yu, published in BMC Cancer 2012; 12: 243. DOI: 10.1186/1471-2407-12-243. The first paragraphs of both discussions are identical. This is concerning. The abstract and introduction sections have much of their text plagiarized. Overall, there is high plagiarism detected. The GMR editorial staff was alerted and after a thorough investigation, we have strong reason to believe that the peer review process was failure and, after review and contacting the authors, the editors of Genetics and Molecular Research decided to retract the article in accordance with the recommendations of the Committee on Publication Ethics (COPE). The authors and their institutions were advised of this serious breach of ethics.

Abstract
BACKGROUND Ethnic differences in total body fat (fat mass [FM]) have been reported in adults and children, but the timing of when these differences manifest and whether they are present at birth are unknown. OBJECTIVES This study aimed to assess whether ethnic differences in body fat are present at birth in healthy infants born at term, where body fat is measured using air displacement plethysmography and fat distribution by skin-fold thickness. METHODS Data were from a multiracial cross-sectional convenience sample of 332 term infants from four racial or ethnic groups based on maternal self-report (A, Asian; AA, non-Hispanic Black [African-American]; C, non-Hispanic White; and H, Hispanic). The main outcome measure was infant body fat at 1-3 days after birth, with age, birth weight, gestational age and maternal pre-pregnancy weight as covariates. RESULTS Significant effects for race (P = 0.0011), sex (P = 0.0051) and a race by sex interaction (P = 0.0236) were found. C females had higher FM than C males (P = 0.0001), and AA females had higher FM than AA males (P = 0.0205). C males had less FM than A males (P = 0.0353) and H males (P = 0.0001). CONCLUSION Race/ethnic and sex differences in FM are present in healthy term newborns. Although the implications of these differences are unclear, studies beginning in utero and birth set the stage for a life course approach to understanding disease later in life.

Abstract
This study was performed to identify and analyze the phylogenetic relationship among four herbaceous species of the genus Paeonia, P. lactiflora, P. japonica, P. veitchii, and P. suffruticosa, using DNA barcodes. These four species, which are commonly used in traditional medicine as Paeoniae Radix and Moutan Radicis Cortex, are pharmaceutically defined in different ways in the national pharmacopoeias in Korea, Japan, and China. To authenticate the different species used in these medicines, we evaluated rDNA-internal transcribed spacers (ITS), matK and rbcL regions, which provide information capable of effectively distinguishing each species from one another. Seventeen samples were collected from different geographic regions in Korea and China, and DNA barcode regions were amplified using universal primers. Comparative analyses of these DNA barcode sequences revealed species-specific nucleotide sequences capable of discriminating the four Paeonia species. Among the entire sequences of three barcodes, marker nucleotides were identified at three positions in P. lactiflora, eleven in P. japonica, five in P. veitchii, and 25 in P. suffruticosa. Phylogenetic analyses also revealed four distinct clusters showing homogeneous clades with high resolution at the species level. The results demonstrate that the analysis of these three DNA barcode sequences is a reliable method for identifying the four Paeonia species and can be used to authenticate Paeoniae Radix and Moutan Radicis Cortex at the species level. Furthermore, based on the assessment of amplicon sizes, inter/intra-specific distances, marker nucleotides, and phylogenetic analysis, rDNA-ITS was the most suitable DNA barcode for identification of these species.

Abstract
Dear Editor, We read the article "Association between the interleukin-6-174 G/C polymorphism and risk of ischemic stroke: a meta-analysis" by Jin et al. (2015) with great interest. The authors searched the literature for data sources to analyze the relationship between interlerukin-6-174G/C and ischemic stroke. Their meticulousness in study selection and data extraction is highly commendable. Of all the studies included in this meta-analysis, we were particularly interested in the extraction of data reported by Banerjee et al. (2008). For this study, Jin et al. (2015) considered all the 176 patients in the ischemic-stroke group, although 64 of them had hemorrhagic stroke. According to pathology, ischemic stroke and hemorrhagic stroke are two of the three main types of stroke (Rodgers, 2013). Each has several subtypes, with distinct underlying vascular pathologies; their pathogenesis has also been distinguished. Inflammation and genetic factors play an important role in the development of ischemic stroke (Gao et al., 2006; Jin et al., 2010). Moreover, ischemic stroke is characterized by thrombus, which is a complex process mainly induced by either hyper- or hypo-tension (Tong et al., 2016). On the contrary, hemorrhagic stroke is mainly attributed to various environmental and genetic risk factors, and is triggered by cerebral hemorrhage (Ikram et al., 2012). Ischemic stroke is usually accompanied by the occurrence of hemorrhagic transformation in patients, especially after thrombolytic therapy (Jickling et al., 2014). Thus, ischemic stroke and hemorrhagic stroke involve related, but different processes. Ideally, Jin et al. (2015) should have considered data for the 112 patients with ischemic stroke for their meta-analysis, instead of those for all the 176 patients. The result of this study would also have been more accurate and reliable. Further, in the second paragraph of the discussion section in this paper, the authors stated that, "This is the first systematic study of the association between the IL6 -174 G/C polymorphism and ischemic stroke risk using meta-analysis." However, we would like to bring to your notice that there have been a few meta-analytical studies on the association between IL6-174G/C polymorphism and ischemic stroke (Ye et al., 2012; Kumar et al., 2015). The literature included in Ye et al. (2012) meta-analysis is not as extensive as that in the study by Jin et al. (2015). The study by Kumar et al. (2015) included more relevant literatures. The results of these three studies are similar. All of them concluded that IL-6-174G/C gene polymorphisms may not be associated with an increased susceptibility to ischemic stroke. Thus, we suggest more attention should be paid to these relevant studies. Undoubtedly, a more systematic and comprehensive approach to literature searching was required in the study by Jin et al. (2015).
