Abstract
Objective: To explore the difference in end tidal PCO(2) (P(ET)CO(2)) between idiopathic pulmonary arterial hypertension (IPAH) and chronic thromboembolic pulmonary hypertension (CTEPH), and to analyze the correlation between P(ET)CO(2) and the indexes of disease severity in IPAH and CTEPH patients. Methods: Data were retrieved from 68 IPAH patients and 52 CTEPH patients who all had received right-heart catheterization, pulmonary function test and cardiopulmonary exercise testing at Shanghai Pulmonary Hospital from October 2011 to October 2014. In addition, other clinical parameters were also collected. Results: The IPAH group had a significantly higher mPAP, PVR [(60±16) mmHg (1 mmHg=0.133 kPa), (13±6) Wood U ] than the CTEPH group [(46±12) mmHg, (9±4) Wood U, t=4.90, 4.83, all P<0.01]. Meanwhile, the IPAH group had a lower percentage of predicted peakVO(2), oxygen pulse [(45±15)%, (60±22)%] compared with the CTEPH group [(53±16)%, (68±21)%, t=-2.42, -1.96, all P<0.05]. The value of P(ET)CO(2) at rest, AT, peak in the IPAH patients [(27±5), (28±7), (25±7) mmHg] were higher than those in the CTEPH patients [(24±4) mmHg, (23±6) mmHg, (21±6) mmHg, t=3.22-4.54, all P<0.01]. There was a significantly difference in P(ET)CO(2) at AT and peak between WHO-FC Ⅰ-Ⅱ and Ⅲ-Ⅳ subgroups in IPAH (t=2.55, 2.60, all P<0.05) and CTEPH (t=2.39, P<0.05), except for P(ET)CO(2) at peak in the CTEPH patients (t=1.71, P>0.05). A moderately inverse correlation was found between P(ET)CO(2) at AT and NT-proBNP in the IPAH group (r=-0.58, P<0.01), meanwhile P(ET)CO(2) at AT in the CTEPH group was weakly correlated with NT-proBNP (r=-0.34, P<0.05). Conclusions: Compared with the CTEPH patients, the IPAH patients had significantly decreased exercise capacity and increased P(ET)CO(2). P(ET)CO(2) could reflect the disease severity in both IPAH and CTEPH patients, being superior in IPAH than in CTEPH. Furthermore, P(ET)CO(2) at AT might be better than P(ET)CO(2) at peak in reflecting the ventilatory efficiency.

Abstract
OBJECTIVE To explore the feasibility and short-term effectiveness of the modified radical resection and reconstruction in the treatment of malignant proximal humerus tumor. METHODS The relevant anatomic data from 30 normal adult shoulder joint MRI were measured to analyze the feasibility of modified radical resection and reconstruction surgery in the treatment of malignant proximal humerus tumor. Five patients with malignant proximal humerus tumor were treated by using the modified radical resection and reconstruction surgery between March 2012 and January 2016. There were 1 male and 4 females, aged from 9 to 69 years (median, 46 years). There were 4 cases of osteosarcoma (Enneking IIA in 2 cases and Enneking IIB in 2 cases) and 1 case of metastatic carcinoma (moderately differentiated adenocarcinoma). The disease duration was 7 to 12 months (mean, 9 months). Recurrence of tumor was observed after operation, and the shoulder function was assessed according to Enneking skeletal muscle tumor function scoring system. RESULTS Radiographic results showed that modified radical resection and reconstruction surgery was feasible, which was in allowable range of the maximum longitudinal diameter (<29.8 mm) and depth (<4 mm). The operation was successfully completed in all 5 cases, and pathological examination suggested that purposes of radical resection had achieved. All patients were followed up 3 to 49 months (mean, 15.6 months). One patient had local recurrence at 12 months after operation, and a shoulder joint amputation was performed; the other 4 patients had good prosthesis survival. At last follow-up, the function of the shoulder joint was obviously recovered when compared with preoperative function; Enneking's skeletal muscle tumor function score was 25.8 points (range, 24 to 27 points). CONCLUSIONS Modified radical resection and reconstruction surgery is feasible for the treatment of proximal humerus tumor, and it can maintain a good early shoulder function.

Abstract
We aimed to describe the surgical technique and clinical outcomes of
paraspinal-approach reduction and fixation (PARF) in a group of patients with Denis
type B thoracolumbar burst fracture (TLBF) with neurological deficiencies. A total of
62 patients with Denis B TLBF with neurological deficiencies were included in this
study between January 2009 and December 2011. Clinical evaluations including the
Frankel scale, pain visual analog scale (VAS) and radiological assessment (CT scans
for fragment reduction and X-ray for the Cobb angle, adjacent superior and inferior
intervertebral disc height, and vertebral canal diameter) were performed
preoperatively and at 3 days, 6 months, and 1 and 2 years postoperatively. All
patients underwent successful PARF, and were followed-up for at least 2 years.
Average surgical time, blood loss and incision length were recorded. The sagittal
vertebral canal diameter was significantly enlarged. The canal stenosis index was
also improved. Kyphosis was corrected and remained at 8.6±1.4o (P>0.05)
1 year postoperatively. Adjacent disc heights remained constant. Average Frankel
grades were significantly improved at the end of follow-up. All 62 patients were
neurologically assessed. Pain scores decreased at 6 months postoperatively, compared
to before surgery (P<0.05). PARF provided excellent reduction for traumatic
segmental kyphosis, and resulted in significant spinal canal clearance, which
restored and maintained the vertebral body height of patients with Denis B TLBF with
neurological deficits.

Abstract
OBJECTIVE To investigate the effect of zinc ion on the expression of osteoblastic proteins. METHODS Mice osteoblasts MC3T3-E1 cells were subcultured. Inflammatory environment model was established by tumor necrosis factor α(TNF-α)at a concentration of 10 mg/L. According to different concentration of Zn(2+), the cells were divided into TNF-α group, control group, group A(TNF-α+10(-4) mol/L Zn(2+)), group B(TNF-α+10(-5) mol/L Zn(2+)), group C(TNF-α+10(-6) mol/L Zn(2+)). After 24, 48, and 72 h of culture, cell counting kit-8(CCK-8)assay was used to analyze the proliferation of the cells. ALP activity was examined. Bone morphogenetic protein-2(BMP-2), Runt-related transcription factor 2(RUNX2), Osterix and receptor activator of NF-κB ligand(RANKL)protein levels were determined by Western blotting after 72 h of culture. RESULTS The cells grew by adherence after 24 h. After 72 h, the cells grew dense, and the cells showed long spindle shape or irregular shape. The proliferation of osteoblasts in TNF-α group, group B and group C became lower than that in the control group(P<0.05), and was not significantly different between group A and the control group(P >0.05). ALP activity examination demonstrated that the groups cultured for 72 h revealed the highest ALP activity and the most prominent differentation compared with 24 h and 48 h groups. ALP activity was significantly decreased in TNF-α group, group B and group C compared with control group(P<0.05), but was not significantly different between group A and control group(P>0.05). The protein levels of BMP-2, RUNX2 and Osterix were significantly decreased in TNF-α group, group B and group C compared with control group(P<0.05), while showed no significant difference between group A and the control group. Protein level of RANKL was significantly increased in TNF-α group, grope B and group C compared with control group(P<0.05), while showed no significant difference between group A and control group. CONCLUSIONS The concentration of 10(-4) mol/L Zn(2+) can significantly increase the expression of osteoblastic proteins such as ALP, BMP-2, RUNX2, Osterix and decrease the expression of RANKL in mice osteoblasts in TNF-α inflammatory environment.

Abstract
OBJECTIVE N1-guanyl-1, 7-diaminoheptane (GC7), an inhibitor of deoxyhypusine synthase has been shown to exhibit significant anti-cancer activity. However, the biological role of eukaryotic translation initiation factor 5A2 activation (EIF5A2) and GC7 on drug resistance in non-small cell lung cancer (NSCLC) has not been investigated. In this study, we aimed to investigate the therapeutic effect of GC7 combined with cetuximab in NSCLC therapy. MATERIALS AND METHODS The current study used cell viability assays, EdU incorporation assays, and western blot to detect that the GC7 exhibited synergistic cytotoxicity with cetuximab in NSCLC. RESULTS CCK-8 assays showed that combined treatment with GC7 and cetuximab significantly inhibited the viabilities in three NSCLC cell lines. In addition, EdU incorporation assays also indicated that GC7 co-treatment remarkably enhanced the cetuximab sensitivity in NSCLC cells. Nevertheless, down-regulation of EIF5A2 diminished the regulatory role of GC7 in cetuximab cytotoxicity. Western blot showed that transfection of EIF5A2 siRNA significantly suppressed the protein expression of EIF5A2 in NSCLC cells. CONCLUSIONS These findings demonstrate that combined treatment with GC7 could enhance cetuximab sensitivity by inhibiting EIF5A2 in NSCLC cells, implying the potential clinical application of GC7 in cetuximab-based chemotherapy for NSCLC patients.

Abstract
The long noncoding RNAs (lncRNAs) have long been clarified to participate in hepatocellular carcinoma (HCC) as a biomarker. We carried out the present study in order to identify HCC-related lncRNAs and elucidate the functional roles in the development and progression of HCC. Our previous study has provided that LINC01225 may be an HCC-related gene. Here, we verified that LINC01225 was upregulated in HCC. Knockdown of LINC01225 resulted in inhibited cell proliferation and invasion with activated apoptosis and cell cycle arrest in vitro. Overexpression of LINC01225 in LINC01225 knockdown cells presented that attenuated cell proliferation and invasion were restored and enhanced. Subcutaneous and tail vein/intraperitoneal injection xenotransplantation model in vivo validated reduced tumor progression and metastasis. Investigation of mechanism found that LINC01225 could bind to epidermal growth factor receptor (EGFR) and increase the protein level of EGFR, and subsequently fine tune the EGFR/Ras/Raf-1/MEK/MAPK signaling pathway. Analysis with clinicopathological information suggested a high expression of LINC01225 is positively associated with poor prognosis. We also proved that LINC01225 was stably expressed in serum and can act as a novel biomarker in predicting the diagnosis of HCC. As a conclusion, LINC01225 plays a crucial role in HCC and can act as a biomarker for the diagnosis and prognosis of HCC.

Abstract
OBJECTIVE To establish a model for a high-volume intracranial carotid bypass operation. METHODS High-volume internal carotid-middle cerebral artery bypass was performed on 9 cadaver heads with arteries of porcine forearms as grafts by 6 residents with no previous experience in vascular anastomosis on cadavers. The intima was dissected immediately after the anastomoses were completed to observe the patency of anastomosis. RESULTS After different duration periods of training using this model, 36 vascular anastomoses on 18 sides were successfully performed by the 6 residents with a self-made difficulty regulation device. As the difficulty level increased, the time needed for anastomosis lengthened and patency rate showed a decreasing trend. As the amount of training increased, the residents were able to decrease the amount of time to complete the operation with increasing patency rates. CONCLUSIONS The model of high-volume internal carotid-middle cerebral artery bypass with arteries of porcine forearms has the advantages of material similarity, easy access of grafts, better simulation of intraoperative conditions, and adjustable difficulties. Our results suggest that this new procedure has a better simulation-training platform which is closer to the real surgical procedure for surgeons willing to master the technique of a high-volume bypass operation.

Abstract
Tooth organogenesis depends on genetically programmed sequential and reciprocal inductive interactions between the dental epithelium and neural crest-derived mesenchyme. Previous studies showed that the Msx1 and Runx2 transcription factors are required for activation of odontogenic signals, including Bmp4 and Fgf3, in the early tooth mesenchyme to drive tooth morphogenesis through the bud-to-cap transition and that Runx2 acts downstream of Msx1 to activate Fgf3 expression. Recent studies identified Osr2 as a repressor of tooth development and showed that inactivation of Osr2 rescued molar tooth morphogenesis in the Msx1(-/-) mutant mice as well as in mice with neural crest-specific inactivation of Bmp4. Here we show that Runx2 expression is expanded in the tooth bud mesenchyme in Osr2(-/-) mutant mouse embryos and is partially restored in the tooth mesenchyme in Msx1(-/-)Osr2(-/-) mutants in comparison with Msx1(-/-) and wild-type embryos. Whereas mandibular molar development arrested at the bud stage and maxillary molar development arrested at the bud-to-cap transition in Runx2(-/-) mutant mice, both mandibular and maxillary molar tooth germs progressed to the early bell stage, with rescued expression of Msx1 and Bmp4 in the dental papilla as well as expression of Bmp4, p21, and Shh in the primary enamel knot in the Osr2(-/-)Runx2(-/-) compound mutants. In contrast to the Msx1(-/-)Osr2(-/-) compound mutants, which exhibit nearly normal first molar morphogenesis, the Osr2(-/-)Runx2(-/-) compound mutant embryos failed to activate the expression of Fgf3 and Fgf10 in the dental papilla and exhibited significant deficit in cell proliferation in both the dental epithelium and mesenchyme in comparison with the control embryos. These data indicate that Runx2 synergizes with Msx1 to drive tooth morphogenesis through the bud-to-cap transition and that Runx2 controls continued tooth growth and morphogenesis beyond the cap stage through activation of Fgf3 and Fgf10 expression in the dental papilla.

Abstract
We investigated the effect of p38MAPK/AP-1 (activator protein-1) signaling on the apoptosis of osteoblasts induced by high glucose. A lentivirus vector of small hairpin RNA (shRNA) targeting p38MAPK was constructed in vitro. Osteoblasts MC3T3-E1 cultured in vitro were treated with vehicle, high glucose, p38MAPK-shRNA transfection, p38MAPK inhibitor, and unrelated shRNA transfection. Apoptosis, protein levels of p38MAPK, and activities of AP-1 in MC3T3-E1 osteoblasts were measured using TUNEL and flow cytometry, Western blot analysis, and an electrophoretic mobility shift assay. Compared with the vehicle group, high glucose induced apoptosis of MC3T3-E1 osteoblasts and activated p38MAPK and AP-1. p38MAPK-shRNA transfection blocked the effect of high glucose stimulation, and the p38MAPK inhibitor showed similar effects as those observed in p38MAPK transfection. Unrelated shRNA had no effect on these changes in MC3T3-E1 osteoblasts induced by high glucose. Therefore, our results suggest that p38MAPK-shRNA reduce apoptosis of MC3T3-E1 osteoblasts induced by high glucose by inhibiting the p38MAPK-AP-1 signaling pathway.

Abstract
Genome-wide gene expression measurements have enabled comprehensive studies that integrate the changes of gene expression and phenotypic information to uncover their novel associations. Here we reported the association analysis between psychophysical phenotypes and genome-wide gene expression changes in human adaptation to one of the most extreme climates on Earth, the Antarctic Dome Argus. Dome A is the highest ice feature in Antarctica, and may be the coldest, driest and windiest location on earth. It is considered unapproachable due to its hostile environment. In 2007, a Chinese team of 17 male explorers made the expedition to Dome A for scientific investigation. Overall, 133 psychophysical phenotypes were recorded, and genome-wide gene expression profiles from the blood samples of the explorers were measured before their departure and upon their arrival at Dome A. We found that mood disturbances, including tension (anxiety), depression, anger and fatigue, had a strong, positive, linear relationship with the level of a male sex hormone, testosterone, using the Pearson correlation coefficient (PCC) analysis. We also demonstrated that significantly lowest-level Gene Ontology groups in changes of gene expression in blood cells with erythrocyte removal were consistent with the adaptation of the psychophysical characteristics. Interestingly, we discovered a list of genes that were strongly related to significant phenotypes using phenotype and gene expression PCC analysis. Importantly, among the 70 genes that were identified, most were significantly related to mood disturbances, where 42 genes have been reported in the literature mining, suggesting that the other 28 genes were likely novel genes involved in the mood disturbance mechanism. Taken together, our association analysis provides a reliable method to uncover novel genes and mechanisms related to phenotypes, although further studies are needed.

Cell Death Dis 2014; 5:e1549. [PMID: 25476897 PMCID: PMC4649834 DOI: 10.1038/cddis.2014.518] [Citation(s) in RCA: 142] [Impact Index Per Article: 14.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2014] [Revised: 10/27/2014] [Accepted: 10/28/2014] [Indexed: 12/15/2022]
Abstract
Location-associated long noncoding RNA (lncRNA) was reported to interact with target protein via a cis-regulatory process especially for the Flank10kb class lncRNA. Based on this theory, we aimed to explore the regulatory mechanisms of Linc00974 and KRT19 (an lncRNA beyond the Flank10kb class with protein) when we first confirmed the aberrant expression in hepatocellular carcinoma in a previous study. Knockdown of Linc00974 resulted in an inhibition of cell proliferation and invasion with an activation of apoptosis and cell cycle arrest in vitro, which was also validated by a subcutaneous and tail vein/intraperitoneal injection xenotransplantation model in vivo. We further investigated the interaction pattern of Linc00974 and KRT19. MiR-642 was identified, by acting as the competing endogenous RNA in regulating Linc00974 and KRT19. Linc00974 was increased owing to an abnormal hypomethylation promoter, which induced the upregulation of KRT19 via ceRNA interaction, resulting in the activation of the Notch and TGF-β pathways as detected by cDNA microarray. We also discovered Linc00974F-1 stably expressed in the plasma. By the combined analysis of Linc00974F-1 with CYFRA21-1, we found that these joint indicators predicted growth and metastasis of tumor in HCC patients. In conclusion, the combination of Linc00974 and KRT19 may be novel indices for clinical diagnosis of tumor growth and metastasis in HCC, while Linc00974 may become a potential therapeutic target for the prevention of HCC progression.

Li P, Jiang R, Li L, Liu C, Yang F, Qiu Y. Correlation of serum adiponectin and adiponectin gene polymorphism with metabolic syndrome in Chinese adolescents. Eur J Clin Nutr 2014; 69:62-7. [PMID: 25074391 DOI: 10.1038/ejcn.2014.152] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2014] [Revised: 06/23/2014] [Accepted: 06/26/2014] [Indexed: 12/16/2022]
Abstract
BACKGROUND/OBJECTIVES To investigate the association of adiponectin and its gene polymorphisms with metabolic syndrome (MetS) and cardiovascular disease (CVD) risk factors in Chinese adolescents. SUBJECTS/METHODS This cross-sectional study enrolled 919 healthy middle school students (aged 11-16 years; 46.7% females). All participants underwent anthropometric and biochemical examinations, and MetS was diagnosed using 2007 International Diabetes Federation criteria. The presence of adiponectin and its genotypes of single nucleotide polymorphisms (SNPs) rs266729 (-11377C/G), rs2241766 (+45T/G) and rs1501299 (+276G/T) was detected. RESULTS (1) Serum adiponectin levels were negatively correlated with numerous CVD risk factors (all P<0.05), and following adjustments for confounding factors, a lower adiponectin level was an independent risk factor for MetS (odds ratio=5.59; 95% confidence interval: 1.90, 16.41). Central obesity and low levels of high-density lipoprotein cholesterol were positively associated with MetS and reduced serum adiponectin levels. (2) The genotype and frequencies of SNP-11377 and SNP+276 in a MetS group and non-MetS group were not significantly different. Subjects with genotype SNP+45 GG were at higher risk for MetS compared with subjects with genotypes SNP+45 TT (P=0.033) or TT+TG (P=0.021). Subjects with genotype SNP+276 TT or TT+TG had higher levels of serum adiponectin compared with subjects with SNP+276 GG (P=0.012 and 0.014, respectively). CONCLUSIONS Adiponectin may be used as a predictive biomarker of MetS, and shows a significant association with CVD risk factors in Chinese adolescents. Adiponectin gene polymorphisms are associated with serum adiponectin concentrations and the presence of MetS.
