Abstract
OBJECTIVE The aim of this study was to investigate the expression of PTPN12 in human breast cancer and its role in predicting the efficacy of neoadjuvant chemotherapy (NACT) for breast cancer. PATIENTS AND METHODS The PTPN12 expression levels were assessed by immunohistochemical staining in 114 breast cancer patients. The correlation of PTPN12 with clinicopathological features was also analyzed. Multivariate logistic regression was used to explore the effect of PTPN12 expression in predicting clinical response. RESULTS We observed a significant association of PTPN12 expression with cTNM classification. The overall pathological complete response (pCR) rate was 23.2 % in high PTPN12 expression group, whereas it was 5.2% in low PTPN12 expression group. The multivariate regression analyses further indicated that clinical response correlated with PTPN12 expression level and cycles of NACT, and CEX regimen was associated with the overall pathological complete response. In addition, Spearman rank correlation analyses suggested that higher PTPN12 expression indicated better clinical response in breast cancer patients. Furthermore, PTPN12 expression statistically related with pathological response in TNBC and Luminal B subtypes, as assessed by Pearson Chi-square test or Fisher's exact test. CONCLUSIONS Our study informed that cTNM classification is an independent risk factor for PTPN12 expression and PTPN12 is an independent predictor to clinical remission.

Abstract
Colorectal cancer (CRC) is one of the most common malignancies in Western countries. Over the last 20 years, and the last decade in particular, the clinical outcome for patients with metastatic CRC (mCRC) has improved greatly due not only to an increase in the number of patients being referred for and undergoing surgical resection of their localised metastatic disease but also to a more strategic approach to the delivery of systemic therapy and an expansion in the use of ablative techniques. This reflects the increase in the number of patients that are being managed within a multidisciplinary team environment and specialist cancer centres, and the emergence over the same time period not only of improved imaging techniques but also prognostic and predictive molecular markers. Treatment decisions for patients with mCRC must be evidence-based. Thus, these ESMO consensus guidelines have been developed based on the current available evidence to provide a series of evidence-based recommendations to assist in the treatment and management of patients with mCRC in this rapidly evolving treatment setting.

Abstract
BACKGROUND The clinical value of the prognostic nutritional index (PNI) in gastric cancer (GC) remains controversial. Therefore, we performed the meta-analysis to determine the prognostic and clinicopathological values of PNI in patients with GC. METHODS A literature search was performed in the PubMed, Embase, and Web of Science databases. Hazard ratios (HRs) and odds ratios (ORs) were extracted to estimate the association of PNI with survival and clinicopathological characteristics, respectively. RESULTS Ten studies involving 3396 patients with GC were analyzed. The pooled results indicated that a low PNI was a significant predictor of poor overall survival (OS) (HR = 1.89, 95% confidence interval [CI] = 1.67-2.13, P < 0.01) and postoperative complications (OR = 1.74, 95% CI = 1.41-2.16, P < 0.01). In the subgroup analysis, a low PNI was significantly associated with poor OS in patients with GC at stage I, II and III, but not at stage IV (HR = 1.14, 95% CI = 0.84-1.55, P = 0.40). Moreover, a low PNI was significantly associated with more advanced tumor features, such as older age, deeper depth of tumor, positive lymph node metastasis, more advanced TNM stages, and positive vessel and lymphatic invasion. CONCLUSION PNI was a predictive indicator of survival and postoperative complications, and was associated with clinicopathological features in GC patients. However, a low PNI was not significantly associated with poor OS in patients with GC at stage IV.

Abstract
Osteoarthritis (OA) is the most prevalent degenerative joint disease with multifactorial etiology caused by risk factors such as ageing, obesity and trauma. Previously, it was reported that the inhibition of microRNA-34a (miR-34a) may reduce rat chondrocyte apoptosis induced by IL-1β, whereas the molecular mechanism and the role of miR-34a in human chondrocyte as well as in OA progression remains to be determined. In the current study, using MTT, luciferase reporter assays and western blot analysis we identified that miR-34a was upregulated while silent information regulator 1 (SIRT1) was inhibited in chondrocytes from 12 OA patients compared with healthy chondrocytes from 10 trauma amputees. Overexpression of miR-34a promoted apoptosis and inhibited cell proliferation in human chondrocytes. Transfection with miR-34a mimic inhibited SIRT1 expression, which attenuated the deacetylation of p53, leading to the upregulation of Bax and downregulation of Bcl-2. Furthermore, results from the western blot analysis and luciferase reporter assay demonstrated that SIRT1 was directly regulated by miR-34a in human chondrocytes. A rat model of OA was induced through anterior cruciate ligament transection and medial meniscus resection (ACLT+MMx). The results showed that the intra-articular injection of lentiviral vector encoding anti-miR-34a sequence effectively ameliorated the progression of OA. The results suggest that miR-34a has a crucial role in the pathogenesis of OA through direct regulation of the SIRT1/p53 signaling pathway and serves as a potential therapeutic target of OA.

Abstract
Lung cancer, especially adenocarcinoma, is one of the leading causes of death in the world. Carcinoembryonic antigen (CEA), a superb non-small-cell lung cancer marker candidate, showed a beneficial effect in cancer therapy with oncolytic adenovirus in recent studies. Cancer-targeting dual gene-virotherapy delivers two therapeutic genes, linked by a connexon, in the replication-deficient vector instead of one gene so that they can work in common. In this study, we constructed a tumor-specific oncolytic adenovirus, CD55-TRAIL-IETD-MnSOD. The virus has the fusion protein complementary DNAs for tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and for manganese superoxide dismutase (MnSOD) complementary DNA linked through a 4-amino acid caspase-8 cleavage site (IETD), and uses a CEA promoter to control virus E1A express. This is the first work to use a CEA promoter-regulated oncolytic adenovirus carrying two therapeutic genes for cancer research. Its targeting and anticancer capacity was evaluated by in vitro and in vivo experiments. The results indicated that CD55-TRAIL-IETD-MnSOD caused more cell apoptosis than CD55-TRAIL or CD55-MnSOD alone, or their combination in vitro, with low cytotoxicity of normal cells. In the A549 tumor xenograft model in nude mice, data showed that CD55-TRAIL-IETD-MnSOD could effectively suppress tumor growth than single gene groups, with no histological damage in liver, spleen or kidney tissues. Thus, the CEA-regulated dual-gene oncolytic virus CD55-TRAIL-IETD-MnSOD may be a novel potential therapy for lung cancer.

Abstract
BACKGROUND/AIMS Spinal cord injury (SCI) is a severe health problem worldwide. Ryanodine receptors (RyRs) are a class of intracellular calcium channels in various excitable tissues such as muscles and nervous tissues. The current study was designed to investigate the possible role of RyR2 upregulation in SCI and to elucidate the possible molecular mechanisms. METHODS Rats were injected with LVshRNAi- RyR2 and then exposed to spinal cord contusion injury. RESULTS The results showed that knockdown of RyR2 significantly promoted the recovery of structural and functional injury in spinal cord, as evidenced by reduction of lesion volume and increase of Basso, Beattie and Bresnahan (BBB) and combined behavioral score (CBS) scores. Knockdown of RyR2 inhibited the increase of proinflammatory cytokines, including IL-1β and TNFα. Moreover, downregulation of RyR2 increased oxygen consumption rate and decreased the expression of glucose-regulated protein 78 (GRP78), activating transcription factor 3 (ATF3) and ATF6, indicating the improvement of mitochondrial dysfunction and endoplasmic reticulum stress after SCI. Furthermore, silence of RyR2 reduced oxidative stress, as reflected by decrease of TBARS and GSSG content and increase of GSH level. The expression of NADPH oxidase 2 (NOX2), NOX4 and p66(shc) were increased in SCI rats. Knockdown of RyR2 significantly decreased NOX2 expression, but had no evident effect on NOX4 and p66shc expression. These results indicated NOX2 may be involved in RyR2-induced ROS generation which mediated contusion-induced spinal cord injury. CONCLUSION The data provide novel insights into the mechanism of RyR2-mediated injury and the potential therapeutic targets for injury in spinal cord.

Abstract
Metastasis is a leading cause of mortality for osteosarcoma patients. The molecular pathological mechanism remains to be elucidated. In the previously study, we established two osteosarcoma cell lines with different metastatic potentials. Differential expressed genes and proteins regarding metastatic ability have been identified. MicroRNAs are important regulators in tumorigenesis and tumor progression. In this study, microRNA microarray was used to assess the differential expressed miRNAs level between these two cell lines. One of the top ranked miRNAs-miR-195 was identified highly expressing in lowly metastatic cells. It was showed that over-expression of miR-195 substantially inhibits migration and invasion of osteosarcoma cells in vitro and pulmonary metastasis formation in vivo. Meanwhile, CCND1 was identified as the target gene of miR-195 and further studied. More importantly, Using real-time PCR, we evaluated the expression of miR-195 and CCND1 in osteosarcoma samples from 107 frozen biopsy tissues and 99 formalin- or paraformalin-fixed, paraffin-embedded (FFPE) tissues. Results indicated lowly expressed miR-195 or highly CCND1 correlated with positive overall survival and their expression inverse relate to each other. In summary, our study suggests miR-195 function as a tumor metastasis suppressor gene by down-regulating CCND1 and can be used as a potential target in the treatment of osteosarcoma.

Abstract
BACKGROUND Although the single-radius (SR) femoral design is known to have theoretical advantages in many aspects, studies of clinical outcomes that compare the SR with the multiple-radius (MR) femoral design are controversial. We performed a meta-analysis to address the hypothesis that a SR femoral design in primary total knee arthroplasty improves patient outcomes. METHODS The meta-analysis identified 15 articles reporting the clinical outcomes of 2212 knee replacements using the SR (n = 948) compared with the multiradius (MR; n = 1361) femoral design. Comparing SR with MR, we examined the Knee Society Score for the knee (KSS-knee), KSS-function, knee flexion, range of motion, complications, isometric peak torque of knee, and survival rate. RESULTS The range of motion of SR knees was lower than that of MR knees. No differences were found in the analyses of KSS-knee, KSS-function, knee flexion, complications, isometric peak torque of the knee, and survival rate. CONCLUSION Our meta-analysis does not provide clinical support for the previously reported theoretical advantages of the SR implant design.

Abstract
Different clinical results have been reported in the repair of extensor mechanism disruption using fresh-frozen complete extensor mechanism (CEM) allograft, creating a need for a better understanding of fresh-frozen CME allograft reconstruction. Here, we perform histological and biomechanical analyses of fresh-frozen CEM allograft or autograft reconstruction in an in vivo rabbit model. Our histological results show complete incorporation of the quadriceps tendon into the host tissues, patellar survival and total integration of the allograft tibia, with relatively fewer osteocytes, into the host tibia. Vascularity and cellularity are reduced and delayed in the allograft but exhibit similar distributions to those in the autograft. The infrapatellar fat pad provides the main blood supply, and the lowest cellularity is observed in the patellar tendon close to the tibia in both the allograft and autograft. The biomechanical properties of the junction of quadriceps tendon and host tissues and those of the allograft patellar tendon are completely and considerably restored, respectively. Therefore, fresh-frozen CEM allograft reconstruction is viable, but the distal patellar tendon and the tibial block may be the weak links of the reconstruction. These findings provide new insight into the use of allograft in repairing disruption of the extensor mechanism.

Abstract
OBJECTIVES Dietary recommendations to reduce blood pressure (BP) have been widely disseminated and residents who live on islands have unique dietary characteristics. Here, we identified associations between dietary intake and BP levels among island residents in China. DESIGN Cross-sectional study. SETTING The Changhai islands, which is an important island county in China. PARTICIPANTS A total of 876 residents, 18-88 years old, of Changhai county. MEASUREMENTS Dietary intake and BP measurements were assessed using standardized questionnaires and protocols, respectively. Dietary intake was compared across BP categories and linear regression analyses were performed between dietary intake and systolic blood pressure (SBP) and diastolic blood pressure (DBP). RESULTS Participants previously diagnosed with hypertension consumed less salt than those with undiagnosed high BP (p < 0.01). After exclusion of participants previously diagnosed with hypertension, salt and meat consumption were positively and linearly associated with both SBP (p < 0.01 and < 0.001, respectively) and DBP (p = 0.03 and < 0.01, respectively), whereas consumption of marine products was inversely associated with SBP (p = 0.047). Mixed edible oil and edible oil consumption were associated with SBP (p < 0.01) and DBP (p = 0.021), respectively. In the multiple linear regression model, meat intake was positively associated with both SBP and DBP (β = 0.139, p < 0.001; β = 0.066, p = 0.047, respectively), whereas consumption of marine products was inversely associated with SBP (β = -0.102, p <0.001), while mixed edible oil was associated with SBP (β = 0.062, p = 0.03). CONCLUSION Adherence to nutritional recommendations can be improved among hypertensive patients, even those aware of their conditions. In the general island population, eating habits regarding salt, meat, edible oil consumption, and use of mixed edible oil increased the risk of hypertension onset, whereas marine products were found to decrease this risk.

Abstract
Half-metallic Co-based full-Heusler alloys with perpendicular magnetic anisotropy (PMA), such as Co2FeAl in contact with MgO, are receiving increased attention recently due to its full spin polarization for high density memory applications. However, the PMA induced by MgO interface can only be realized for very thin magnetic layers (usually below 1.3 nm), which would have strong adverse effects on the material properties of spin polarization, Gilbert damping parameter, and magnetic stability. In order to solve this issue, we fabricated oxidized Co50Fe25Al25 (CFAO) films with proper thicknesses without employing the MgO layer. The samples show controllable PMA by tuning the oxygen pressure (PO2) and CFAO thickness (tCFAO), large perpendicular anisotropy field of ~8.0 kOe can be achieved at PO2 = 12% for the sample of tCFAO = 2.1 nm or at PO2 = 7% for tCFAO = 2.8 nm. The loss of PMA at thick tCFAO or high PO2 results mainly from the formation of large amount of CoFe oxides, which are superparamagnetic at room temperature but become hard magnetic at low temperatures. The magnetic CFAO films, with strong PMA in a relatively wide thickness range and small intrinsic damping parameter below 0.028, would find great applications in developing advanced spintronic devices.

Abstract
BACKGROUND/OBJECTIVES Folic acid supplementation has been suggested to reduce the risk of preeclampsia. However, results from few epidemiologic studies have been inconclusive. We investigated the hypothesis that folic acid supplementation and dietary folate intake before conception and during pregnancy reduce the risk of preeclampsia. SUBJECTS/METHODS A birth cohort study was conducted in 2010-2012 at the Gansu Provincial Maternity & Child Care Hospital in Lanzhou, China. A total of 10,041 pregnant women without chronic hypertension or gestational hypertension were enrolled. RESULTS Compared with nonusers, folic acid supplement users had a reduced risk of preeclampsia (OR=0.61, 95% CI: 0.43-0.87). A significant dose-response of duration of use was observed among women who used folic acid supplemention during pregnancy only (P-trend=0.007). The reduced risk associated with folic acid supplement was similar for mild or severe preeclampsia and for early- or late-onset preeclampsia, although the statistical significant associations were only observed for mild (OR=0.50, 95% CI: 0.30-0.81) and late-onset (OR=0.60, 95% CI: 0.42-0.86) preeclampsia. The reduced risk associated with dietary folate intake during pregnancy was only seen for severe preeclampsia (OR=0.52, 95% CI: 0.31-0.87, for the highest quartile of dietary folate intake compared with the lowest). CONCLUSIONS Our study results suggest that folic acid supplementation and higher dietary folate intake during pregnancy reduce the risk of preeclampsia. Future studies are needed to confirm the associations.
