Abstract
Purpose Glioblastoma multiforme (GBM) is a highly malignant tumor of the central nervous system. Although primary GBM patients receive extensive therapies, tumors may recur within months, and there is no objective and scientific method to predict prognosis. Adoptive immunotherapy holds great promise for GBM treatment. However, the expression profiles of the tumor-associated antigens (TAAs) and tumor immune microenvironment (TME) genes used in immunotherapy of GBM patients have not been fully described. The present study aimed to develop a predictive tool to evaluate patient survival based on full analysis of the expression levels of TAAs and TME genes. Methods Expression profiles of a panel of 87 TAAs and 8 TME genes significantly correlated with poor prognosis were evaluated in 44 GBM patients and 10 normal brain tissues using quantitative real-time polymerase chain reaction (qRT-PCR). A linear formula (the LASSO algorithm based in the R package) weighted by regression coefficients was used to develop a multi-element expression score to predict prognosis; this formula was cross-validated by the leave-one-out method in different GBM cohorts. Results After analysis of gene expression, clinical features, and overall survival (OS), a total of 8 TAAs (CHI3L1, EZH2, TRIOBP, PCNA, PIK3R1, PRKDC, SART3 and EPCAM), 1 TME gene (FOXP3) and 4 clinical features (neutrophil-to-lymphocyte (NLR), number of basophils (BAS), age and treatment with standard radiotherapy and chemotherapy) were included in the formula. There were significant differences between high and low scoring groups identified using the formula in different GBM cohorts (TCGA (n=732) and GEO databases (n=84)), implying poor and good prognosis, respectively. Conclusion The multi-element expression score was significantly associated with OS of GBM patients. The improve understanding of TAAs and TMEs and well-defined formula could be implemented in immunotherapy for GBM to provide better care.

Abstract
Abstract
Background
Previous meta-analyses, through internal, within-study comparisons of women and men participants, have observed that women with diabetes are at substantially higher risk of coronary heart disease (CHD), stroke and gastric cancer compared with affected men. However, the magnitude of the excess risk of these and other cause-specific outcomes that is conferred by diabetes for men and women is unknown.
Purpose
To estimate the relative effect of diabetes on risk of all-cause, cancer, cardiovascular disease (CVD), infectious disease and respiratory disease mortality in women compared with men.
Methods
Studies published from their inception to April 1, 2018, identified through a systematic search of PubMed and EMBASE and review of references. We used the sex-specific RRs to derive the women-to-men ratio of RRs (RRR) and 95% CIs from each study. Subsequently, the RRR for each outcome was pooled with random effects meta-analysis weighted by the inverse of the variances of the log RRRs.
Results
Forty-eight studies with 85 prospective cohorts met the inclusion criteria and were eligible for analysis. The pooled women to men RRR showed a 13% greater risk of all-cause mortality associated with diabetes in women than in men (RRR: 1.13, 95% CI: 1.07 to 1.19; P<0.001, Figure 1). The pooled multiple-adjusted RRR indicated a 30% significantly greater excess risk of CVD mortality in women with diabetes compared with men (RRR: 1.30 95% CI: 1.13 to 1.49; P<0.001). Compared with men with diabetes, women with diabetes had a 58% greater risk of coronary heart disease (CHD) mortality, but only an 8% greater risk of stroke mortality (RRRCHD: 1.58, 95% CI: 1.32 to 1.90; P<0.001; RRRstroke: 1.08, 95% CI: 1.01 to 1.15; P<0.001). However, no sex differences were observed among the population with or without diabetes, for all-cancer (RRR: 1.02, 95% CI: 0.98 to 1.06; P=0.21), infectious (RRR: 1.13, 95% CI: 0.90 to 1.38; P=0.33) and respiratory mortality RRR: 1.08, 95% CI: 0.95 to 1.23; P=0.26).
Conclusions
Compared with men with the same condition, women with diabetes have a 58% and 13% greater risk of CHD and all-cause mortality, respectively. This points to an urgent need to develop sex and gender specific risk assessment strategies and therapeutic interventions that target diabetes management for CHD prevention.

Abstract
We have demonstrated that Na/K-ATPase acts as a receptor for reactive oxygen species (ROS), regulating renal Na+ handling and blood pressure. TALLYHO/JngJ (TH) mice are believed to mimic the state of obesity in humans with a polygenic background of type 2 diabetes. This present work is to investigate the role of Na/K-ATPase signaling in TH mice, focusing on susceptibility to hypertension due to chronic excess salt ingestion. Age-matched male TH and the control C57BL/6J (B6) mice were fed either normal diet or high salt diet (HS: 2, 4, and 8% NaCl) to construct the renal function curve. Na/K-ATPase signaling including c-Src and ERK1/2 phosphorylation, as well as protein carbonylation (a commonly used marker for enhanced ROS production), were assessed in the kidney cortex tissues by Western blot. Urinary and plasma Na+ levels were measured by flame photometry. When compared to B6 mice, TH mice developed salt-sensitive hypertension and responded to a high salt diet with a significant rise in systolic blood pressure indicative of a blunted pressure-natriuresis relationship. These findings were evidenced by a decrease in total and fractional Na+ excretion and a right-shifted renal function curve with a reduced slope. This salt-sensitive hypertension correlated with changes in the Na/K-ATPase signaling. Specifically, Na/K-ATPase signaling was not able to be stimulated by HS due to the activated baseline protein carbonylation, phosphorylation of c-Src and ERK1/2. These findings support the emerging view that Na/K-ATPase signaling contributes to metabolic disease and suggest that malfunction of the Na/K-ATPase signaling may promote the development of salt-sensitive hypertension in obesity. The increased basal level of renal Na/K-ATPase-dependent redox signaling may be responsible for the development of salt-sensitive hypertension in polygenic obese TH mice.

Abstract
Pneumonic-type adenocarcinoma (P-ADC) is a subtype of lung adenocarcinoma with high mortality, which often requires lobectomy surgery. Nonsurgically treated P-ADC patients usually have more advanced or complex conditions, which remain poorly understood and pose a major challenge in clinical management. We aimed to describe the clinical profiles and prognosis of non-surgically treated P-ADC patients. We enrolled 71 patients with pathologically proven P-ADC from a university hospital in China. Clinical and laboratory data were retrieved from medical record. Their median age was 62 years, including 45% men and 35% smokers. Clinical manifestations were dominated by cough, sputum, and dyspnea. Main chest imaging features included nodules, shadow, consolidation, and air bronchogram. Nearly half or more of patients showed higher levels of inflammation and cancer biomarkers including cytokeratin-19-fragment (CYFRA 21-1) and carcinoembryonic antigen (CEA). Majority of patients were classified at the stage IIIB or IV. Palliative care was the most popular treatment option but provided a shorter overall survival compared to tyrosine kinase inhibitor therapy, standard chemotherapy, and sequential therapy while there were no significant differences in the survival among the latter 3 options. Higher serum CEA was associated with longer survival and better prognosis while higher serum CYFRA 21-1 could predict a poor prognosis. Detailed understanding the clinical characteristics and prognostic factors in nonsurgically treated P-ADC may allow the identification of patients with particular risk factors and initiation of early and specific treatment in order to optimize outcomes.

Abstract
We tackle the problem of dense reconstruction with a practical system, in which near point lighting (NPL) is employed. Different from the conventional formulation of photometric stereo (PS) that assumes parallel lighting, PS under the NPL condition is a nonlinear problem as the local surface normals are coupled with its distance to the camera as well as the light sources. After obtaining the locations of point lights by a calibration process, we develop a new framework to solve this nonlinear reconstruction problem via mesh deformation, in which each facet is corresponding to a pixel in the image captured by the camera. In our framework, mesh deformation is decoupled into an iteration of interlaced steps of local projection and global blending. Experimental results verify that our method can generate accurate estimation of surface shape under NPL in a few iterations. Besides, this approach is robust to errors on the positions of light sources and is easy to be implemented.

Abstract
This systematic review evaluated whether single nucleotide polymorphisms of AMH and AMHRII genes are associated with ovarian function. A literature search of PubMed and Embase was complemented by hand searches in the reference lists. Eight studies involving 3155 participants were included in a meta-analysis and 10 studies included for description. For AMH c.146T>G polymorphism, no significant difference in serum anti-Müllerian hormone (AMH) levels was found between participants with different genotypes (weighted mean difference [WMD] 0.42, 95% confidence interval [CI] -0.16 to 0.99). Subgroup analyses showed similar results for the European region and in healthy and infertile populations. Regarding AMHRII -482 A>G, there was no significant difference in serum AMH levels between participants with A/A genotype and G/A or G/G genotype carriers (WMD -0.04, 95% CI -0.31 to 0.23). In subgroup analysis, an interesting trend was confirmed in healthy women and polycystic ovary syndrome (PCOS) patients (WMD -0.36, 95% CI -0.63 to -0.09, P = 0.009; WMD 0.46, 95% CI 0.15 to 0.77, P = 0.004). The review suggests that AMH c.146T>G is not associated with AMH levels, while AMHRII -482 A>G may be related to AMH levels in PCOS and healthy subgroups. However, the impact of polymorphisms in the AMH signalling pathway on ovarian function still requires further investigation.

Abstract
MicroRNAs (miRNAs) have been confirmed to participate in liver fibrosis progression and activation of hepatic stellate cells (HSCs). In this study, the role of miR‐193a/b‐3p in concanavalin A (ConA)‐induced liver fibrosis in mice was evaluated. According to the results, the expression of miR‐193a/b‐3p was down‐regulated in liver tissues after exposure to ConA. Lentivirus‐mediated overexpression of miR‐193a/b‐3p reduced ConA‐induced liver injury as demonstrated by decreasing ALT and AST levels. Moreover, ConA‐induced liver fibrosis was restrained by the up‐regulation of miR‐193a/b‐3 through inhibiting collagen deposition, decreasing desmin and proliferating cell nuclear antigen (PCNA) expression and lessening the content of hydroxyproline, transforming growth factor‐β1 (TGF‐β1) and activin A in liver tissues. Furthermore, miR‐193a/b‐3p mimics suppressed the proliferation of human HSCs LX‐2 via inducing the apoptosis of LX‐2 cells and lowering the levels of cell cycle‐related proteins Cyclin D1, Cyclin E1, p‐Rb and CAPRIN1. Finally, TGF‐β1 and activin A‐mediated activation of LX‐2 cells was reversed by miR‐193a/b‐3p mimics via repressing COL1A1 and α‐SMA expression, and restraining the activation of TGF‐β/Smad2/3 signalling pathway. CAPRIN1 and TGF‐β2 were demonstrated to be the direct target genes of miR‐193a/b‐3p. We conclude that miR‐193a/b‐3p overexpression attenuates liver fibrosis through suppressing the proliferation and activation of HSCs. Our data suggest that miR‐193a‐3p and miR‐193b‐3p may be new therapeutic targets for liver fibrosis.

Abstract
In recent years, environmental endocrine disruptors (EEDs) have received extensive attention because of their hormone-like or anti-hormone effects. Dibutyl phthalate (DBP) is not only one of the most widely-used phthalates but also a member of EEDs with the estrogenic property. Although some studies have revealed the negative effect of DBP on the reproductive system, the underlying mechanisms are still elusive. Here the effect of DBP on P450 aromatase, a rate-limiting enzyme stimulated by FSH in the estradiol synthesis, was investigated in human granulosa cell line KGN. Cultured cells were treated with FSH and various doses of DBP (0.1μM, 1μM, 10μM, 50μM, or 100μM) for 24hr. Then the expression of aromatase was assessed, and the synthesis of estradiol was detected to reflect aromatase activity. As shown by the results, all concentrations of DBP could up-regulate the mRNA as well as protein levels of aromatase, and 0.1μM DBP increased the production of estradiol significantly. Furthermore, the ovary-specific promoter of aromatase, promoter II, was activated by 0.1μM DBP, and the expression of FSH receptor (FSHR) was increased by DBP from 0.1μM to 100μM. The study results show that DBP can affect aromatase from both quantitative and functional aspects, and this process may involve the activation of aromatase promoter II and upregulation of FSHR in KGN. Additionally, low-concentration DBP, near human serum concentration, has a more robust effect. This study suggests that DBP may affect the steroidogenic capacity in human ovaries and contributes to our understanding of the effects of DBP on the female reproductive system.

Abstract
Abstract
Aim
This study aimed to develop a nomogram based on clinicopathological features to evaluate the recurrence probability of breast phyllodes tumors following surgery. The criteria for atypia, mitoses, overgrowth, and surgical margin (AMOS) were also validated.
Method
Data from 334 patients with breast phyllodes tumors, who underwent surgical treatment at Sun Yat-sen Memorial Hospital from January 2005 to December 2014, were used to develop a prediction model. Additionally, data of 36 patients from Peking University Shenzhen Hospital and data of 140 patients from Sun Yat-sen University Cancer Center during the same period were used to validate the model. The medical records and tumor slides were retrospectively reviewed. The log-rank and Cox regression tests were used to develop a clinical prediction model of breast phyllodes tumors as well as validating the AMOS criteriaAll statistical analyses were performed using R and STATA.
Results
Of all 334 patients included in the study, 224 had benign, 91 had borderline, and 19 had malignant tumors. The local and distant recurrence rate was 17.7%. The 1-,3-, and 5-year cumulative recurrence-free survival was 98.5%, 97.9%, and 96.8%, respectively. Surgical margin, mitoses, and tumor border were identified as independent risk factors for breast phyllodes tumors. A nomogram was developed based on these three variables. The C-index of internal and external validation was 0.71and 0.67, respectively. The area under the curve of AMOS criteria was 0.59.
Conclusions
The present study model presented a more concise and objective variables to evaluate the recurrence-free survival of patients after surgery compared with that using the AMOS criteria, which is more appropriate for clinical practice and also allows for a more accurate prediction.

Abstract
(5S,10R)-5-methyl-10,11-dihydro-5H-dibenzo(A,D)cyclohepten-5,10-imine hydrogen maleate (MK-801) is an N-methyl-D-aspartate non-competitive antagonist that possesses useful biological properties, including anticonvulsant and anesthetic activities. Studies have indicated the rapid antidepressant effects of MK-801 in animal models. However, there are no reports concerning a sustained antidepressant effect in the chronic unpredictable mild stress (CUMS) model. Furthermore, the antidepressant mechanism remains unclear. The aim of the present study was to examine the effects of MK-801 (0.1 mg/kg) and rapastinel (10 mg/kg) on depression-like behavior in CUMS mice and measure the protein expression of brain-derived neurotrophic factor (BDNF), α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (GluA1) and phosphorylated mammalian target of rapamycin (p-mTOR). In the tail suspension and forced swim tests, MK-801 significantly attenuated the increased immobility time in CUMS mice compared with the vehicle group. In the sucrose preference test, a single-dose injection of MK-801 significantly ameliorated the decreased sucrose preference in CUMS mice compared with the vehicle group. Western blot analyses indicated that MK-801 significantly attenuated the decreased BDNF, GluA1 and p-mTOR protein levels in the medial prefrontal cortex (mPFC), dentate gyrus (DG) and CA3 of the hippocampi of CUMS mice. Conversely, this compound had no effect on increased BDNF, GluA1 and p-mTOR protein levels in the nucleus accumbens of CUMS mice. Therefore, the present study revealed the sustained antidepressant effects of MK-801 in the CUMS model. Furthermore, synaptogenesis and neuronal regeneration in the prelimbic regions of mPFC, DG and CA3 of the hippocampus may be implicated as mechanisms that promote a sustained antidepressant response.

Abstract
The aim of this study was to explore the effect of depression of different degrees on inflammatory response and immune function in patients with ovarian cancer. One hundred and eight cases of ovarian cancer according to the Federation Internationale of Gynecologie and Obstetrigue (FIGO) stage II~III who visited the Gynecology Department of Affiliated HongQi Hospital of MuDanJiang Medical University between September 2015 and May 2017 were enrolled in the study. After being hospitalized, they were divided into two groups according to their Beck Depression Inventory (BDI) scores. The total score of BDI is 63, with 0~4 for the normal group (25 cases), 5~13 for the mild depression group (24 cases), 14~20 for the moderate depression group (28 cases), and 21~63 for the severe depression group (31 cases). The immune function, inflammatory reaction, tumor markers [CA125, human epididymis protein-4 (HE4), insulin-like growth factor-I (IGF-I)], platelet technology and D-dimer index were compared between the four groups. The results showed that there were different levels of depression in patients with ovarian cancer in II~III stage, and the degree of depression could stimulate the level of serum-6, and TNF -α in serum increased. The proportion of CD3+, CD4+ and NK cells in patients with severe depression decreased, and their immunity also decreased. Depression increased the levels of CA125, HE4 and IGF-I in serum and ascites of ovarian cancer patients, and increased the risk of tumor progression and recurrence. Hypercoagulability existed in patients with ovarian cancer, and tumor associated depression could increase platelet count in plasma and increase D-dimer level. To sum up, depression can affect the level of micro inflammation in patients with ovarian cancer. In particular, depression can reduce cellular immune responses, affect the progression free survival of ovarian cancer patients, and reduce their overall survival rate.

Abstract
The quantitative analysis of multiple indexes remains an important quality evaluation method of traditional Chinese medicine (TCM) herbal formulas. The Chinese Pharmacopoeia 2015 only stipulates the content of a single component, specnuezhenide, in Erzhiwan composed of the Fructus Ligustri Lucidi (FLL) powder and aqueous extracts of Herba Ecliptae (HE). To generalize the intrinsic quality of Erzhiwan, a novel C30-HPLC method with good precision, accuracy, and reproducibility was developed for the simultaneous determination of six compounds, including two isomers, and then an analytic hierarchy process was further applied to integrate and discriminate the quality of four samples prepared via different methods. The results of the analysis were in agreement with the antioxidant tests in vitro. This comprehensive strategy could provide a reference and suggestions for the improvement of the quality evaluation method of TCM herbal formulas.

Abstract
OBJECTIVE To evaluate the efficacy and metabolic safety of long-term treatment with ethinyl oestradiol/cyproteroneand desogestrel/ethinyl oestradiol tablets in women with polycystic ovary syndrome (PCOS). METHODS Women with PCOSfrom West China Second Hospital of Sichuan University enrolled between September, 2011 and August, 2013 were randomlyallocated to receive either ethinyl oestradiol/cyproterone tablets (Group A, n=355) or desogestrel/ethinyl oestradiol tablets(Group B, n=357) for a prospective observation period of 6 months. Women with insulin resistance also received metformin. Atbaseline, 3 months, and 6 months, the patients were evaluated for menstruation, acne score, body mass index (BMI), waist-tohip ratio (WHR), plasma levels of sex hormones, fasting blood glucose (FPG), HOMA-insulin resistance index (HOMA-IR), serum lipid, ovarian volume, and the number of ovarian follicles. RESULTS All the patients had a regular menstrual cycle aftertreatments. Testosterone level, acne score, LH/FSH, ovarian volume, and the number of follicles decreased significantly afterthe treatments without significant differences between the two groups. Significant increases were noted in TG, TCh, LDL, HDL, and AIP, and HDL level in group A as compared with group B (P < 0.001). FPG decreased in both groups, and wassignificantly lower in group B at 6 months (P < 0.05). BMI and WHR decreased in all the patients with insulin resistance aftercombination treatment with metformin (P < 0.05), but increased significantly in patients without insulin resistance (P < 0.05). Ingroup A, HOMA- IR significantly increased in patientswithout insulin resistance at 3 months (P < 0.05), whereas asignificant increase was not observed until 6 months ingroup B (P < 0.05). CONCLUSIONS Both ethinyl oestradiol/cyproterone tablets and desogestrel/ethinyl oestradioltablets can relieve the symptoms of PCOS, but it isadvisable to assess the risk of cardiovascular diseasebefore the treatments.

Abstract
The receptor activator of NF-κB ligand-induced osteoclast differentiation has a critical role in the process of bone metabolism. Overactivation of osteoclastogenesis may result in a series of diseases. Irisin, a novel myokine, which was first reported in 2012, has been proposed to mediate the beneficial metabolic effects of exercise. Studies have demonstrated that irisin targets osteoblasts by promoting osteoblast proliferation and differentiation; however, the underlying mechanism regarding the effect of irisin on osteoclasts remains elusive. Using 2 types of osteoclast precursor cells, RAW264.7 cells and mouse bone marrow monocytes, we showed that irisin promoted osteoclast precursor cell proliferation but inhibited osteoclast differentiation. Irisin down-regulated the expression of osteoclast differentiation marker genes, including receptor activators of NF-κB, nuclear factor of activated T cells, cytoplasmic 1, cathepsin K, and tartrate-resistant acid phosphatase (TRAP), as well as decreasing the number of TRAP-positive multinucleated cells and hydroxyapatite resorption pits. Furthermore, we showed that irisin suppressed the NF-κB signaling pathway, but activated the p38 and JNK signaling pathways. In the presence of an inhibitor of p38 and JNK, irisin-induced promotion of RAW264.7 cell proliferation was attenuated. However, irisin-induced inhibition of osteoclast differentiation was not affected by either the p38 or JNK signaling pathway. Our study suggested the direct effect of irisin on osteoclastogenesis and revealed the mechanism responsible for the therapeutic potential of irisin in bone metabolism disease.-Ma, Y., Qiao, X., Zeng, R., Cheng, R., Zhang, J., Luo, Y., Nie, Y., Hu, Y., Yang, Z., Zhang, J., Liu, L., Xu, W., Xu, C.

Abstract
Fibrosis induces a progressive loss of liver function, thus leading to organ failure. Activins are secreted proteins that belong to the transforming growth factor (TGF)-β superfamily, which initiate signaling by binding to their two type II receptors: Activin A receptor type 2A (ACVR2A) and activin A receptor type 2B. Previous studies that have explored the mechanisms underlying immune-induced hepatic fibrosis have mainly focused on TGF-β signaling, not activin signaling. To investigate the role of the activin pathway in this disease, adenovirus particles containing short hairpin (sh)RNA targeting ACVR2A mRNA (Ad-ACVR2A shRNA) were administered to mice, which were chronically treated with concanavalin A (Con A). The pathological changes in the liver were evaluated with hematoxylin/eosin staining, Masson trichrome staining and immunohistochemical assay. The results detected an increase in serum activin A and liver ACVR2A in Con A-treated animals. Conversely, liver function was partially restored and fibrotic injury was attenuated when activin signaling was blocked. In addition, the activation of hepatic stellate cells (HSCs) in response to Con A was suppressed by Ad-ACVR2A shRNA, as evidenced by decreased α-smooth muscle actin, and type I and IV collagen expression. Furthermore, primary mouse HSCs (mHSCs) were activated when exposed to interleukin (IL)-17A or IL-17F, which are two major cytokines produced by cluster of differentiation 4+ T helper 17 cells. The levels of activin A, type I and IV collagen were determined with ELISA kits and the expression of fibrotic molecules was determined with western blot analysis. Conversely, blocking activin/ACVR2A impaired the potency of HSCs to produce collagens in response to IL-17s. In addition, C terminus phosphorylation of Smad2 on Ser465 and Ser467, induced by either Con A in the liver or by IL-17s in mHSCs, was partly inhibited when activin A/ACVR2A signaling was suppressed. Collectively, the present study demonstrated an involvement of activated activin A/ACVR2A/Smad2 signaling in immune-induced hepatic fibrosis.
