Abstract
AbstractThis study aims to compare clinical outcomes in unicompartmental knee arthroplasty (UKA) patients with or without magnetic resonance imaging (MRI) evidence of bone marrow edema (BME) in the patella and to evaluate the effect of functional outcomes after UKA in patients with patellofemoral osteoarthritis (PF OA). Outcomes of 146 knees in 141 patients who underwent medial UKA were included. According to their preoperative condition of patellofemoral joints, patients were divided into three groups: Group A, non-PF OA (Kellgren–Lawrence [K–L] scale = 0); group B, PF OA without BME (K–L ≥ 1, bone marrow edema pattern [BMEP] = 0); group C, PF OA with BME (K–L ≥ 1, BMEP ≥ 1). Clinical outcomes including visual analog scale (VAS) scores of knee pain, Hospital for Special Surgery (HSS) scores, and range of motions (ROMs) were evaluated and analyzed at the postoperative follow-up of 3 months and 2 years. From our results, BME was highly correlated to poor outcome in patients with UKA. At follow-up of 3 months, BME influenced the clinical outcome of UKA at an early postoperative stage in terms of VAS scores, HSS scores, and ROMs. At the final follow-up of 2 years, the clinical outcome was improved in terms of HSS score, although the anterior knee pain and active ROMs were still worse than that of patients without BME. In conclusion, there was no significant difference in clinical outcomes in patients without BME regardless of PF OA. However, the condition of BME should be taken serious consideration because of its indication of an adverse effect on the outcome after UKA.

Abstract
Bcl-2/adenovirus E1B 19-kDa interacting protein (BNIP3), a pro-apoptosis protein regulated by the methylation status of its promoter, has been implicated in inducing autophagy. However, the roles of BNIP3 and BNIP3-induced autophagy under hypoxia remain uncertain in esophageal squamous cell carcinoma (ESCC). Two esophageal squamous cancer cell lines, CAES17 and KYSE140, were selected on the basis of the expression and methylation status of BNIP3 to investigate the features of BNIP3 under hypoxia. Hypoxia increased cell death and the expression of BNIP3, whose promoter status was lower methylation, in a time-dependent manner. BNIP3 knockdown by RNA interference downregulated cell death. These studies demonstrated that the exposure of ESCC cells to hypoxia increased the autophagic punctate distribution of MDC staining and GFP-LC3 and that autophagy rate could be inhibited by BNIP3-siRNA. In addition, under hypoxia, cells transfected with BNIP3-siRNA exhibited a lower apoptosis rate than the control, and the apoptosis induced by BNIP3 exhibited a caspase-independent manner. Furthermore, the administration of the autophagic inhibitor 3-methyladenine (3-MA) could augment BNIP3-induced cell apoptosis and death, suggesting that autophagy plays a protective role under hypoxia. Together, our studies indicated that BNIP3 exerts prodeath effects through the induction of caspase-independent apoptosis under hypoxia in ESCC, though BNIP3-induced autophagy acting as a survival mechanism.

Abstract
Tumor-associated macrophages (TAMs) play an essential role in metastasis. However, what enables TAMs to have a superior capacity to establish pre-metastatic microenvironment in distant organs is unclear. Here we have begun to uncover the effects of cytochrome P450 (CYP) 4A in TAMs on lung pre-metastatic niche formation and metastasis. CYP4A+ TAM infiltration was positively associated with metastasis, pre-metastatic niche formation and poor prognosis in breast cancer patients. The pharmacological inhibition of CYP4A reduced lung pre-metastatic niche formation (evidenced by a decrease in vascular endothelial growth factor receptor 1 positive (VEGFR1+) myeloid cell recruitment and pro-metastatic protein expression) and metastatic burden, accompanied with TAM polarization away from the M2 phenotype in spontaneous metastasis models of 4T1 breast cancer and B16F10 melanoma. Co-implantation of 4T1 cells with CYP4A10high macrophages promoted lung pre-metastatic niche formation and metastasis. Depletion of TAMs disrupted lung pre-metastatic niches and thereby prevented metastasis. Treatment with the CM from CYP4A10high M2 macrophages (M2) increased pre-metastatic niche formation and metastatic burden in the lungs, whereas CYP4A inhibition attenuated these effects. In vitro TAM polarization away from the M2 phenotype induced by CYP4A inhibition decreased VEGFR1+ myeloid cell migration and fibronectin expression, accompanied with downregulation of STAT3 signaling. Conversely, overexpression of CYP4A or exogenous addition of 20-hydroxyeicosatetraenoic acid promoted M2 polarization and cytokine production of macrophages and thereby enhanced migration of VEGFR1+ myeloid cells, which were reversed by siRNA or pharmacological inhibition of STAT3. Importantly, a combined blocking M2 macrophage-derived factors TGF-β, VEGF and SDF-1 abolished VEGFR1+ myeloid cell migration and fibroblast activation induced by CYP4A. In summary, CYP4A in TAMs is crucial for lung pre-metastatic niche formation and metastasis, and may serve as a potential therapeutic target in human cancer.

Abstract
UNLABELLED We conducted an observational cross-section study to investigate the status of bone mineral mass of Tibetan postmenopausal women with type 2 diabetes and the possible predictors for osteoporosis. We found that prevalence of osteoporosis was 27.0% and blood pressure was an independent risk factor for bone mass loss. INTRODUCTION The aims of this study is to investigate the prevalence of osteoporosis in postmenopausal women with type 2 diabetes dwelling in Tibet and the possible risk factors for bone mass loss. METHODS We recruited 99 Chinese Tibetan postmenopausal women with type 2 diabetes from the department of endocrinology of People's Hospital Tibet Autonomous Region. Multiple sites of bone mineral density (BMD) were measured by dual-energy X-ray absorptiometry (DXA). The subjects were divided into three groups based on BMD T-score: osteoporosis, osteopenia, and normal. The clinical characteristics were compared between groups. The risk factors for bone mass loss were assessed by multiple linear regression analysis. RESULTS Among diabetic postmenopausal women dwelling in high altitude, mean age was 62 ± 8 years, the median postmenopausal period was 12 years (5, 20), the median duration of diabetes mellitus was 3 years (1, 8), and mean BMI was 27.6 ± 4.2 kg/m2. Patients (52.5%) had hypertension. The percentages of patients with osteoporosis, osteopenia and normal BMD were 27.3, 42.4, and 30.3%, respectively. HbA1c and systolic blood pressure (SBP) were independently associated with T-scores of spine; ages and SBP were independently associated with T-scores of femoral neck or hip. CONCLUSIONS Among diabetic postmenopausal women dwelling in high altitude, 27.3% patients have osteoporosis, 42.4% patients have osteopenia, and 30.3% are normal. The BMD T-score of spine was inversely associated with SBP and positively associated with HbA1c, while the BMD T-score of femoral neck or hip was inversely associated with ages and SBP.

Abstract
Recently single-cell whole-exome sequencing (scWES) has deeply expanded and sharpened our knowledge of cancer evolution and subclonality. Herein, with scWES and matched bulk whole-exome sequencing (bulk WES) on two colorectal cancer (CRC) patients with normal or adenomatous polyps, we found that both the adenoma and cancer were of monoclonal origin, and both shared partial mutations in the same signaling pathways, but each showed a specific spectrum of heterogeneous somatic mutations. In addition, the adenoma and cancer further developed intratumor heterogeneity with the accumulation of nonrandom somatic mutations specifically in GPCR, PI3K-Akt and FGFR signaling pathways. We identified novel driver mutations that developed during adenoma and cancer evolution, particularly in OR1B1 (GPCR signaling pathway) for adenoma evolution, and LAMA1 (PI3K-Akt signaling pathway) and ADCY3 (FGFR signaling pathway) for CRC evolution. In summary, we demonstrated that both colorectal adenoma and CRC are monoclonal in origin, and the CRCs further diversified into different subclones with heterogeneous mutation profiles accumulating in GPCR, PI3K-Akt and FGFR signaling pathways. ScWES provides evidence for the importance of mutations in certain pathways that would not be as apparent from bulk sequencing of tumors, and can potentially establish whether specific mutations are mutually exclusive or occur sequentially in the same subclone of cells.

Abstract
The purpose of this study is to analyze the correlation between preoperative/postoperative Cytokeratin 19 (CK19) messenger RNA (mRNA) level in peripheral blood (PB) and the clinical significance in esophageal cancer patients with different clinicopathological factors. We detected the preoperative and postoperative CK19 mRNA level in the PB of 139 esophageal cancer patients who underwent complete resection and evaluated its clinical significance. We found that both the preoperative and postoperative CK19 mRNA level increased in the esophageal cancer patients with lymph node metastasis, relapse or distant metastasis compared with that in cancers without lymph node metastasis, relapse or distant metastasis. High postoperative CK19 mRNA levels indicate a short disease-free survival (DFS) for the whole cohort esophageal cancer patients, whereas the high preoperative CK19 mRNA levels only indicate a short DFS for the esophageal cancer patients with squamous cell carcinoma, TNM III stage, and lymph node metastasis. The dynamic change of CK19 mRNA levels could indicate the prognosis of esophageal cancer patients. The patients with decreasing CK19 mRNA level after surgery had good prognosis, and the patients with changeless CK19 mRNA level had poor prognosis. Taken together, CK19 mRNA levels could be a promising marker in assessing prognosis or assigning treatment for the esophageal cancer patients according to different clinicopathological factors.

Abstract
Tendon calcification has been widely regarded by researchers to result from the osteogenic differentiation of Tendon-Derived Stem Cells (TDSCs) and ectopic mineralization caused by the calcification of cellular matrix. Recent studies have revealed a correlation between the Mg(2+)/Ca(2+) balance and the degeneration or calcification of tendon tissues. Furthermore, the ATP-P2X/P2Y receptor pathway has been shown to play a decisive role in the process of calcification, with calcium exportation from mitochondria and calcium oscillations potentially representing the cohesive signal produced by this pathway. Our previous study demonstrated that matrix calcification is inhibited by magnesium. In this study, we examined the effects of extracellular Mg(2+) on the deposition of calcium phosphate matrix and cellular pathways in TDSCs. The suppression of the export of calcium from mitochondria has also been detected. We found that a high concentration of extracellular Mg(2+) ([Mg(2+)]e) inhibited the mineralization of the extracellular matrix in TDSCs and that 100 μM ATP reversed this inhibitory effect in vitro. In addition, the spontaneous release of ATP was inhibited by high [Mg(2+)]e levels. A high [Mg(2+)]e suppressed the expression of P2X4, P2X5 and P2X7 and activated the expression of P2Y1, P2Y2, P2Y4 and P2Y14. The interaction between Mg(2+) and Ca(2+) is therefore contradictory, Mg(2+) inhibits mitochondrial calcium concentrations, meanwhile it reverses the opening of mPTP that is induced by Ca(2+). JC-1 staining verified the protective effect of Mg(2+) on mitochondrial membrane potential and the decrease induced by Ca(2+). Taken together, these results indicate that high [Mg(2+)]e interferes with the expression of P2 receptors, resulting in decreased extracellular mineralization. The balance between Mg(2+) and Ca(2+) influences mitochondrial calcium exportation and provides another explanation for the mechanism underlying matrix calcification in TDSCs.

Abstract
This study is a contribution to the development of technology for an MgB2-based, cryogen-free, superconducting magnet for an MRI system. Specifically, we aim to demonstrate that a react and wind coil can be made using high performance in-situ route MgB2 conductor, and that the conductor could be operated in conduction mode with low levels of temperature gradient. In this work, an MgB2 conductor was used for the winding of a sub-size, MRI-like coil segment. The MgB2 coil was wound on a 457 mm ID 101 OFE copper former using a react-and-wind approach. The total length of conductor used was 330 m. The coil was epoxy impregnated and then instrumented for low temperature testing. After the initial cool down (conduction cooling) the coil Ic was measured as a function of temperature (15-30 K), and an Ic of 200 A at 15 K was measured.

Abstract
The objective of this work was to assess hypothalamo-pituitary-adrenocortical (HPA) axis dysregulation in overweight diabetic women and investigate the possible mechanism using overweight diabetic rats. Twenty-two overweight diabetic women were recruited alongside 34 lean and 23 overweight healthy women serving as controls. Dexamethasone suppression test (0.25 mg DST) and low dose adrenocorticotropic hormone (ACTH) stimulation assay were used to evaluate the HPA axis activity. Then, high fat diet (HF) and STZ-induced diabetic rats were utilized to investigate the possible mechanism. After measurement of corticosterone circadian patterns and dexamethasone suppression levels, mRNA amounts of mineralocorticoid receptors (MR), glucocorticoid receptors (GR), and 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) were determined by real time PCR at hippocampus, hypothalamus, and pituitary levels. Overweight diabetic women showed impaired HPA axis with negative feedback efficacy (suppression ratio F-DEX%: 0.52±0.06% vs. 0.49±0.06% vs. 0.14±0.08%), as well as increased adrenal cortisol secretion response to low dose ACTH stimulation. Interestingly, F-DEX% was negatively correlated with BMI (r=- 0.323, p=0.003), waist circumference (r=- 0.319, p=0.004), and HbA1c (r=- 0.334, p=0.002). Stepwise linear regression analysis showed F-DEX% was significantly related to HbA1c level (β=- 0.328, p=0.007) after adjusting for other covariates (age, BMI, waist circumference, SBP, TC, TG, and HOMA-IR). Furthermore, 11β-HSD1, MR, and GR mRNA expression levels were reduced at pituitary level while GR expression was downregulated at hippocampus level in HF and HF+STZ rats. In conclusion, hyperactive HPA axis in overweight diabetic subjects may be associated with downregulation of 11β-HSD1, MR, and GR in the brain.

Abstract
PURPOSE We compared dosimetry and clinical toxicity for 3-dimensional conformal radiotherapy (3D-crt), intensity-modulated radiotherapy (imrt), and RapidArc (Varian Medical Systems, Palo Alto, CA, U.S.A.) in locally advanced pancreatic cancer (lapcc). We hypothesized that the technique with better sparing of organs at risk (oars) and better target dose distributions could lead to decreased clinical toxicity. METHODS The study analyzed 280 patients with lapcc who had undergone radiotherapy. The dosimetry comparison was performed using 20 of those patients. Dose-volume histograms for the target volume and the oars were compared. The clinical toxicity comparison used the 280 patients who received radiation with 3D-crt, imrt, or RapidArc. RESULTS Compared with 3D-crt, RapidArc and imrt both achieved a better conformal index, homogeneity index, V95%, and V110%. Compared with 3D-crt or imrt, RapidArc reduced the V10, V20, and mean dose to duodenum, the V20 of the right kidney, and the liver mean dose. Compared with 3D-crt, RapidArc reduced the V35, and V45 of duodenum, the mean dose to small bowel, and the V15 of right kidney. The incidences of grades 3 and 4 diarrhea (p = 0.037) and anorexia (p = 0.042) were lower with RapidArc than with 3D-crt, and the incidences of grades 3 and 4 diarrhea (p = 0.027) were lower with RapidArc than with imrt. CONCLUSIONS Compared with 3D-crt or imrt, RapidArc showed better sparing of oars, especially duodenum, small bowel, and right kidney. Also, fewer acute grades 3 and 4 gastrointestinal toxicities were seen with RapidArc than with 3D-crt or imrt. A technique with better sparing of oars and better target dose distributions could result in decreased clinical toxicities during radiation treatment for lapcc.

Abstract
Mg(++) is widely involved in human physiological processes that may play key roles in the generation and progression of diseases. Osteoarthritis (OA) is a complex joint disorder characterized by articular cartilage degradation, abnormal mineralization and inflammation. Magnesium deficiency is considered to be a major risk factor for OA development and progression. Magnesium deficiency is active in several pathways that have been implicated in OA, including increased inflammatory mediators, cartilage damage, defective chondrocyte biosynthesis, aberrant calcification and a weakened effect of analgesics. Abundant in vitro and in vivo evidence in animal models now suggests that the nutritional supplementation or local infiltration of Mg(++) represent effective therapies for OA. The goal of this review is to summarize the current understanding of the role of Mg(++) in OA with particular emphasis on the related molecular mechanisms involved in OA progression.

Abstract
Unicompartmental knee arthroplasty (UKA) is an efficient surgical treatment for osteoarthritis or avascular osteonecrosis by resurfacing the medial or lateral compartment of the tibiofemoral joint. If compared to total knee arthroplasty (TKA), UKA can reach the same long-term curative effect, but superiority in less invasive soft tissue dissection, preservation of bone stock, minimal blood loss, faster post-operative rehabilitation and less complications. For the last 15 years, the Oxford Knee phase 3 has been implanted through a minimally invasive approach, and multicenter studies using this approach have reported high survival rates at long-term follow-up. Up to now, UKA has accounted for a significant portion of the patients who need knee replacement. However, there remain some controversies on UKA indications, such as the debate regarding associated patellofemoral arthritis as a contraindication for UKA. As clear indications for UKA are usually rare, surgeon's experience seems to be the key factor for a successful selection of patients. Better understanding of indications may add to improved outcome of UKA. This narrative review aims to summarize the current pros and cons to eliminate patellofemoral arthritis (PFA) as a contraindication for UKA.

Abstract
OBJECTIVE In the clinical management of cirrhotic portal hypertension, surgery is often necessary; however, the operative mortality rate is high. PATIENTS AND METHODS Data from 161 patients, who underwent surgery for cirrhotic portal hypertension, were analyzed, and 24 potential predictors of surgical outcome were assessed. A Kruskal-Wallis rank sum test was used for single-factor comparisons, and multivariate logistic regression for multifactor comparisons to identify key factors for poor surgical outcomes and calculate their scores. RESULTS Six predictors of poor surgical outcomes were identified: postoperative bleeding within 30 h of > 2 L, with a score of 3; severe liver atrophy (an anteroposterior diameter of the left lobe of ≤ 55 mm and an oblique diameter of the right lobe ≤ 110 mm), with a score of 3; a base excess of <-3 mmol/L, with a score of 3; a platelet count of <3 T/L, with a score of 2; an amount of intraoperative bleeding of > 2 L, with a score of 2; and a red blood cell count of < 3 G/L, with a score of 1. For patients with good outcome (n = 147), all patients had a score of ≤ 3, except one patient who had a score of 4. With respect to patients who died (n = 14), all had a score of ≥ 5, except one patient who had a score of 4. A significant difference was observed between the two groups (p < 0.05). The mortality was 100% in patients with a score of ≥ 7. CONCLUSIONS Six key factors for poor surgical outcomes were identified in this study. Operative mortality appears to be significantly increased in patients with a score of 5-6. Surgery should be contraindicated in patients with a score of ≥ 7. To reduce mortality, close attention should be paid to preoperative and intraoperative treatment and prevention to achieve a score of < 4.
