Abstract
BACKGROUND AND PURPOSE The efficacy of dual antiplatelet treatment may be modified by many factors. The aim was to assess whether the effect of clopidogrel plus aspirin versus aspirin alone on recurrent stroke would be affected by admission activated partial thromboplastin time (aPTT). METHODS Data were derived from the Clopidogrel in High-Risk Patients with Acute Nondisabling Cerebrovascular Events (CHANCE) trial. A total of 5074 patients were categorized into three groups based on the aPTT distribution according to the 15th and 85th percentile. The primary outcome was any stroke within 90 days. The interaction of aPTT with antiplatelet therapy on stroke risk was assessed with a Cox proportional hazards model with adjustment for covariates. RESULTS In the high aPTT group (defined as ≥35.9 s), stroke occurred in 6.7% of patients in the clopidogrel-aspirin arm and 11.9% in the aspirin arm [adjusted hazard ratio (HR) 0.50; 95% confidence interval (CI) 0.29-0.85]. In the medium aPTT group (24.6-35.8 s), stroke occurred in 7.7% of patients in the clopidogrel-aspirin arm and 11.8% in the aspirin arm (adjusted HR 0.62; 95% CI 0.50-0.75). Furthermore, in the low aPTT group (≤24.5 s), stroke occurred in 11.2% of patients in the clopidogrel-aspirin arm and 9.9% in the aspirin arm (adjusted HR 1.07; 95% CI 0.65-1.62). The interaction P value of antiplatelet therapy with aPTT level at the cut-point of approximately 25 s or below was significant (P < 0.05). CONCLUSIONS Dual antiplatelet therapy was superior to single antiplatelet therapy in the high or medium aPTT group but not in the low aPTT group.

Abstract
Tripartite motif containing 28 (TRIM28) is a transcriptional corepressor of Kruppel-associated box zinc finger protein, which has been reported to participate in carcinogenesis. Nonetheless, whether TRIM28 plays a role in the metastasis of ovarian carcinoma (OC) is unclear and requires further investigation. In this study, two OC cell lines (A2780 and OVCAR-3) with stable low expression of TRIM28 were established via RNA interference. We found that the migratory and invasive ability of TRIM28-silenced OC cells significantly decreased. The expression and activity of matrix metallopeptidase (MMP)-2 and MMP-9 in these OC cells were inhibited. The TRIM28 shRNA also suppressed the epithelial-mesenchymal transition (EMT) of OC cells as evidenced by the up-regulated E-cadherin and the downregulated Vimentin and N-cadherin. Additionally, the Wnt/β-catenin signaling pathway was suppressed in TRIM28-silenced OC cells: the activity of β-catenin was inhibited, the expression of total and nuclear β-catenin, Axin 2, T-cell factor 1 (TCF1) and lymphoid enhancer binding factor 1 (LEF1) were decreased, whereas the phosphorylation of β-catenin at Ser33/37 was enhanced. Further, re-expression of active β-catenin in TRIM28-silenced OC cells partly restored their metastasis in vitro. Taken together, our study demonstrates a contributory role of TRIM28 in OC metastasis in vitro, suggesting TRIM28 as a novel therapeutic target for this malignant tumor.

Abstract
BACKGROUND Salmonella enterica subspecies enterica serovar abortus equi (S. abortus equi) is well known as the aetiological agent of equine abortion. However, abortion caused by S. abortus equi has not been previously described in donkeys. OBJECTIVES To investigate whether S. abortus equi was correlated with an abortion outbreak consisting of 61 abortions. STUDY DESIGN Investigation of the clinical cases using pathoanatomical, bacteriological, serological and molecular approaches. METHODS Autopsies on nine aborted foetuses were performed. Tissue specimens from seven aborted foetuses and two mares were cultured and subjected to detection of equine herpesvirus 1 (EHV-1), equine herpesvirus 4 (EHV-4) and equine arteritis virus (EAV) by polymerase chain reaction. The isolates were serotyped according to the Kaufmann-White scheme and analysed by multi-locus sequence typing (MLST). Detection of EHV and EAV antibodies was performed in all pregnant mares. RESULTS No obvious gross lesions were observed in the foetuses. Nine Gram-negative isolates were obtained from all nine tissue samples and were identified as Salmonella spp. All of the isolates belonged to the B group, the O antigen epitope was 4, 12 and H antigen was not obtained. The isolates of Salmonella were characterised as sequence type (ST) 251. Detection of EHV-1, EHV-4 and EAV was negative. MAIN LIMITATIONS The mechanism that causes abortion in donkeys needs further study and the lack of histological examination. CONCLUSION Salmonella abortus equi was isolated as the single agent and was responsible for the abortions. Equine practitioners should be aware of S. abortus equi infection as a cause of abortion in donkeys.

Abstract
PURPOSE The purpose of this study was to explore the differences between stage T2N0M0 and stage T1N1M0 gastric cancer (GC) and to identify the necessity of adjuvant treatment (AT) for these stages. METHODS Between years 2004 and 2015, 1971 stage IB GC patients who underwent radical surgery were recruited using the Surveillance, Epidemiology and End Results database. We conducted univariate/multivariate analyses, the propensity score matching and evaluated gastric cancer-specific survival (GCSS) and overall survival (OS) with the log-rank test. RESULTS T1N1M0 had a significantly worse survival than T2N0M0 in both GCSS and OS before and after the propensity score matching. Examined lymph nodes (ELN) ≤ 15 and T1N1M0 were independent risk factors for worse GCSS and OS in stage IB GC. The absence of adjuvant chemotherapy (CT) was an independent risk factor for worse GCSS and OS in T1N1M0 but not in T2N0M0. AT demonstrated similar GCSS and OS with surgery alone (SA) for T2N0M0 but better survival for T1N1M0. Compared to CT and adjuvant chemoradiotherapy (CRT) group, SA demonstrated significantly worse GCSS and OS for T1N1M0. There was no significant difference between CT and CRT in both T2N0M0 and T1N1M0 stages. T2N0M0 had a better survival than T1N1M0 in ELN ≤ 15 subgroup. However, similar survival was demonstrated in ELN > 15 subgroup. CONCLUSIONS T2N0M0 GC has a better survival rate than T1N1M0 GC when ELN are ≤ 15. Moreover, T2N0M0 GC may not benefit from AT. T1N1M0 GC requires CT but not adjuvant radiotherapy.

Abstract
Objective: To explore the value of the intraoperative transesophageal echocardiography during the aortic valve reconstruction. Methods: The echocardiographic features were retrospectively summarized in 19 patients (male: 15 cases; female: 4 cases; age ranged from 12 to 65 years, mean age: 37.7 years) with aortic valve reconstruction at Beijing Anzhen Hospital between October 2014 and October 2016. Results: The findings of the neo-aortic valve on the transesophageal echocardiography included the slightly thickened and hyperechogenicity of the commission, especially the central coaptation point of the neo-valve. Trace aortic regurgitation was noted in 9 cases after operation, mild aortic regurgitation in 1 case and no aortic regurgitation in 9 cases. The velocity of the aortic valve increased significantly in 2 cases. Compared with pre-operation, the diameter of ascending aorta[(32.7±6.1) mm vs (36.4±6.3) mm, P<0.001]and the inner diameter of left ventricle[(48.3±6.1) mm vs (59.1±7.3) mm, P<0.001]decreased significantly after operation, the coaptation length of aortic valve[(6.6±1.3) mm vs (2.2±0.7) mm, P<0.001]significantly increased than that of pre-operation. The mean immediate velocity after operation (175 cm/s) was slightly higher than that (165 cm/s) of 3-month follow-up after surgery, but with no significant difference (P=0.367). Severe aortic regurgitation was found 15 days after operation in 1 case and 12 months after operation in 2 cases. Conclusion: Intraoperative transesophageal echocardiography is a useful tool to evaluate the result of the aortic valve reconstruction.

Abstract
BACKGROUND AND PURPOSE Oxidative stress plays an important role in acute ischaemic stroke. However, the association of oxidative lipoprotein markers, including oxidized low-density lipoprotein (oxLDL), oxLDL:high-density lipoprotein (HDL) and oxLDL:low-density lipoprotein (LDL), with functional outcome of minor stroke or transient ischaemic attack (TIA) remains unclear. We aimed to investigate the association between oxidative lipoprotein markers and poor functional outcome in patients with minor stroke or TIA. METHODS All patients with minor stroke or TIA were recruited from the Clopidogrel in High-Risk Patients With Acute Non-Disabling Cerebrovascular Events (CHANCE) trial. The poor functional outcome included modified Rankin Scale (mRS) score 2-6 and 3-6 at 90-day and 12-month follow-up. Multivariate logistic regression was used to investigate the associations of oxLDL, oxLDL:HDL and oxLDL:LDL with poor functional outcome. RESULTS Among 3019 patients included in this study, the median (interquartile range) oxLDL, oxLDL:HDL and oxLDL:LDL were 13.96 (6.65-28.81), 4.52 (2.08-9.32) and 11.73 (5.27-24.85) μg/dL, respectively. After adjusted for confounding factors, patients in the highest oxLDL quartile had a higher proportion of mRS score 2-6 at 90 days [hazard ratio (HR), 1.78; 95% confidence interval (CI), 1.26-2.52] and 12 months (HR, 1.42; 95% CI, 1.01-1.99), and mRS score 3-6 at 90 days (HR, 1.98; 95% CI, 1.29-3.04) and 12 months (HR, 1.77; 95% CI, 1.09-2.89) when compared with the lowest oxLDL quartile (P < 0.05). Similar results were found for oxLDL:HDL and oxLDL:LDL. CONCLUSIONS Higher levels of oxidative lipoprotein markers are independent predictors of poor functional outcome in patients with minor stroke or TIA at 90 days and 12 months.

Abstract
Objective: To evaluate the efficacy and safety of Saccharomyces boulardii Sachets combined with bismuth quadruple therapy for initial Helicobacter pylori(H.pylori) eradication. Methods: From March 2014 to March 2015, 240 participants from the third hospital of Hebei medical university with H. pylori infection were recruited and randomized into three groups: Quadruple therapy group received bismuth potassium citrate 220 mg bid + Rabeprazole 10 mg bid + amoxicillin 1 000 mg bid+ furazolidone 100 mg bid for 10 days. Short-term group and long-term group received the same quadruple therapy for 10 days as above, as well as Saccharomyces boulardii Sachets 500 mg bid for 14 days and 28 days, respectively. H. pylori eradication was confirmed by (13)C/(14)C-UBT at least 4 weeks after completion of therapy. And side effects were investigated during the therapy. Results: The H. pylori eradication rates in quadruple therapy, short-term and long-term group were 80%, 87.5% and 87.5% by ITT analysis (P=0.321) and 92.8%, 94.6% and 95.9% by PP analysis (P=0.717), respectively. The overall side effect rate and occurrence of diarrhea and abdominal distension were significantly lower in short-term or long-term group as compared with quadruple therapy group(P=0.007, 0.003, 0.004), but there was no significant difference between the two probiotics groups. Conclusions: Both short and long-term Saccharomyces boulardii Sachets reduced the overall side effect rate and occurrence of diarrhea or abdominal distension when combined with bismuth quadruple therapy for initial H. pylori eradication and no difference was observed in efficacy or safety between the two groups.

Abstract
UNLABELLED Pseudovitamin D-deficiency rickets is a rare disease which is caused by CYP27B1. In this study, we identified 9 mutations in 7 PDDR patients. In addition, we observed the response to long-term treatment of calcitriol in 15 Chinese patients with PDDR, which showed that the biochemical abnormalities had been corrected satisfactorily after 1-year treatment. INTRODUCTION Pseudovitamin D-deficiency rickets is a rare autosomal recessive disorder resulting from a defect in 25-hydroxyvitamin D 1α-hydroxylase, which is encoded by CYP27B1. The purpose of this study was to identify the CYP27B1 mutations and investigate the response to long-term treatment of calcitriol in Chinese patients with PDDR. METHODS We investigated CYP27B1 mutations in seven individuals from six separate families. To investigate the response to long-term (13 years) treatment with calcitriol in PDDR patients, we additionally collected clinical data of eight families from our previous report and analyzed their biochemical parameter and radiographic changes during the treatment. RESULTS Nine different mutations were identified: two novel missense mutations (G194R, R259L), three novel and one reported deletion mutations (c1442delA, c1504delA, c311-321del, and c. 48-60del), two novel nonsense mutations (c.85G>T, c.580G>T), and a reported insertion mutation (c1325-1332insCCCACCC). The statistical analysis revealed that parathyroid hormone (PTH) and ALP significantly decreased after 6-month and 1-year treatment with calcitriol respectively. Urine calcium was measured in all the patients without kidney stones being documented. After 6-year treatment, the radiographic abnormalities had also been improved. Two patients who had reached their final height are both with short stature (height Z-score below - 2.0). CONCLUSIONS We identified seven novel mutations of CYP27B1 gene in seven Chinese PDDR families. Our findings revealed after 1-year treatment of active vitamin D3, PTH and ALP significantly decreased. The correction of the biochemical abnormalities had not improved the final height satisfactorily.

Abstract
Background: Programmed cell death protein 1 (PD-1), an immune checkpoint molecule, has recently been recognized as a predictive and prognostic biomarker in several malignant tumors, but its diagnostic value remains largely unknown. Aim: We aimed to investigate the differential diagnostic efficiency of PD-1 and other immune molecules, and propose a panel of immune molecules combined with cancer antigen 15-3 (CA15-3) to distinguish breast cancer (BC) from benign breast disease (BBD). Methods: Ninety-one eligible BC patients and 31 BBD patients were enrolled. Pretreatment peripheral blood was collected and tested for mRNA expression of PD-1, cytotoxic T lymphocyte antigen 4 (CTLA-4), forkhead box P3 (FOXP3), transforming growth factor beta (TGF-β), interleukin-10 (IL-10), IL-2 receptor alpha (IL-2Rα), and cluster of differentiation 28 (CD28) by quantitative real-time PCR. Results: The diagnostic areas under curve (AUCs) of PD-1, IL-2Rα, and IL-10 for BC-BBD discrimination were 0.764, 0.758, and 0.743, respectively. The diagnostic efficiencies of these 2 parameters in distinguishing early-stage or advanced BC from BBD were consistent with a role in BC-BBD discrimination. A panel of PD-1 + IL-10 + IL-2Rα + CA15-3 showed the highest AUC (0.862), with sensitivity of 0.933 and specificity of 0.724, for BC-BBD discrimination. In addition, for early-stage BC discrimination, this panel also had the highest AUC (0.811), with a sensitivity of 0.933 and specificity of 0.614, while for advanced BC discrimination, a panel of PD-1 + IL-10 + CA15-3 exhibited the highest AUC (0.896), with a sensitivity of 0.933 and specificity of 0.783. Conclusion: These data indicate that the panel containing PD-1, IL-2Rα, IL-10, and CA15-3 can effectively discriminate BC from BBD with a high efficiency. After further confirmation, it could be used to complement conventional imaging modalities, especially in discriminating early-stage BC from BBD.

Abstract
Objective: Abnormalities of lipid profile were considered as risk factors of hemorrhage after ischemic stroke. We aimed to determine the relationship between lipid levels and bleeding in minor stroke or transient ischemic attack (TIA) patients receiving antiplatelet therapy. Methods: Serum total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and triglyceride were tested in a subgroup of 3 044 consecutive patients from Clopidogrel in High-risk patients with Acute Non-disabling Cerebrovascular Events (CHANCE) trial. Patients were randomized to clopidogrel plus aspirin group or single aspirin group. The primary endpoint was any bleeding within 90 days. The secondary endpoint was severe bleeding according to the Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Coronary Arteries (GUSTO) definition. Cox proportional hazards models were used to assess the associations of lipid levels and outcomes. Results: A total of 59 (1.9%) bleeding events occurred at 90 days. High-density lipoprotein cholesterol (adjusted HR=2.16; 95%CI 1.17-4.00, P=0.014) and age (adjusted HR=1.04; 95%CI 1.01-1.06, P=0.006) were significantly associated with any bleeding. High-density lipoprotein cholesterol was also associated with severe bleeding (adjusted HR=3.05; 95%CI 1.39-6.68, per 1 mmol/L increase). No correlations between outcomes and levels of total cholesterol, low-density lipoprotein cholesterol and triglyceride were found. There was no interaction of any lipid component level with randomized antiplatelet therapy. Conclusions: Elevated high-density lipoprotein cholesterol is independently associated with any bleeding and severe bleeding in the patients with acute minor stroke or high-risk TIA on antiplatelet therapy.

Abstract
Objective: To investigate the efficacy and safety of Compound Lactobacillus Tablets or Saccharomyces boulardii Sachets combining with bismuth quadruple therapy for Helicobacter pylori(H.pylori) eradication. Methods: A total of 360 H. pylori- infected patients were enrolled and randomly assigned into three groups. Group A received esomeprazole 20 mg bid+ bismuth potassium citrate 220 mg bid+ amoxicillin 1 000 mg bid+ furazolidone 100 mg bid for 10 days. Group B or group C received the same quadruple therapy for 10 days as group A, as well as Compound Lactobacillus Tablets 1 000 mg tid or Saccharomyces boulardii Sachets 500 mg bid for 14 days. Drug-related side effects and adverse reactions were collected during the therapy, and H. pylori eradication results were confirmed by (13)C/(14)C-UBT at least 4 weeks after cessation of therapy. Results: The H. pylori eradication rates in group A, B and C were 81.7%, 84.2% and 85.0% by ITT analysis (P=0.768) and 92.5%, 90.1% and 93.6% by PP analysis (P=0.770), respectively. The overall side effects and adverse reactions rates (P=0.008) and occurrence of diarrhea (P<0.001) were significantly lower in group B than group A. The overall side effect rates (P=0.003) and occurrence of diarrhea (P<0.001), abdominal distension (P=0.004) and constipation(P=0.002) were significantly lower in group C than group A. There was no significant difference in side effects and adverse reactions rates between the two probiotics groups. Conclusions: Both Compound Lactobacillus Tablets and Saccharomyces boulardii Sachets, combining with bismuth quadruple therapy, reduced the overall side effects and adverse reactions rates for H. pylori eradication. Moreover, the former can reduce the incidence of diarrhea, and the latter can reduce the incidence of diarrhea, abdominal distension and constipation.

Abstract
Objective To explore the spatial-temporal characteristics and changing regularities of Schistosoma japonicum infections among human from 2004 to 2011. Methods The township level spatial databases of schistosomiasis in Hunan Province from 2004 to 2011 were established, and the related spatial analysis was performed by SPSS 17.0, ArcGIS 10.1 and SaTScan 7.03. Results The schistosome infection rate among human in Hunan Province sharply decreased from 3.0% in 2004 to 0.8% in 2011. However, the rate among residents in parts of some townships in 2011 was still hovering at a higher level (P90 = 2.12%), and the higher rate was distributed along the Oncomelania hupensis snail ridden areas outside embankment. The autocorrelation analysis showed that the global Moran's I for schistosome infection rate among human was 0.34 to 0.53 from 2004 to 2011, and was higher than the expected value (Z > 8.71, P < 0.05). The local G statistics indicated that the positive hotspot high-high clustering areas were mainly near the coast of Dongting Lake from 2004 to 2011, and the number of townships with schistosomiasis endemic in the clustering areas reached 30 to 70. The spatial scan analysis showed that the number of townships in the clustering areas ran up to 145 to 183 from 2004 to 2011. Conclusions The schistosome infection rate among human decreased significantly in Hunan Province from 2004 to 2011. However, the rate in parts of some townships still remains at a comparatively high level, and there are positive spatial correlation and spatial agglomerations in the schistosome infection rate among human, suggesting that the prevention and control work on schistosomiasis in these areas should be strengthened in the future.

Abstract
BACKGROUND Delayed-type β-lactam hypersensitivity develops in subset of patients. The cellular immunological processes that underlie the drug-specific response have been described; however, little is known about involvement of the humoral immune system. Thus, the aim of this study was to utilize piperacillin hypersensitivity as an exemplar to (i) develop cell culture methods for the detection of drug-specific B-cell responses, (ii) characterize drug-specific IgG subtypes and (iii) assess reactivity of IgG antibodies against proteins modified to different levels with piperacillin haptens. METHODS IgG secretion and CD19+ CD27+ expression on B cells were measured using ELISPOT and flow cytometry, respectively. A piperacillin-BSA adduct was used as an antigen in ELISA antibody binding studies. Adducts generated using different ratios of drug to protein were used to determine the degree of conjugation required to detect IgG binding. RESULTS B cells from hypersensitive patients, but not controls, were stimulated to secrete IgG and increase CD27 expression when cultured with soluble piperacillin. A piperacillin-BSA adduct with cyclized and hydrolysed forms of the hapten bound to eight lysine residues was used to detect hapten-specific IgG 1-4 subclasses in patient plasma. Hapten inhibition and the use of structurally unrelated hapten-BSA adducts confirmed antigen specificity. Antibody binding was detected with antigens generated at piperacillin/BSA ratios of 10:1 and above, which corresponded to a minimum epitope density of 1 for antibody binding. CONCLUSION These data show that antigen-specific B lymphocytes and T lymphocytes are activated in piperacillin-hypersensitive patients. Further work is needed to define the role different IgG subtypes play in regulating the iatrogenic disease.

Abstract
Background 21-hydroxylase deficiency (21 OHD) is the most common form of congenital adrenal hyperplasia (CAH) and it has been widely described in the literature. Adrenocortical incidentalomas are unfrequently the presenting manifestations of CAH, especially in nonclassical form of 21 OHD (NC 21 OHD). Myelolipoma has previously been reported more frequently than other adrenal adenomas associated with CAH. Case We report a 40-year old male case of NC 21 OHD with hypoadrenocorticism after unilateral adrenalectomy of the right side because of a large solid incidentaloma (5×4×4cm3) at the age of 31. This patient began to suffer from obvious symptoms of adrenal insufficiency after 9 years from the surgery. He was reviewed and a very low-density adrenal mass (4.1×3.9cm) was found on computed tomography of the abdomen. After he was admitted to our hospital, this patient was confirmed with NC 21 OHD and presented low level cortisol, striking elevated ACTH, aldosterone insufficiency, increased 17-hydroxyprogesterone, progesterone, decreasing androgens and azoospermatism. Conclusion Patients with 21 OHD could be on risk not only for adrenal hyperplasia, but also to develop adrenal adenomas, particularly if the disease was poorly controlled.

Abstract
Transport of intensity equation (TIE) method can acquire sample phase distributions with high speed and accuracy, offering another perspective for cellular observations and measurements. However, caused by incorrect focal plane determination, blurs and halos are induced, decreasing resolution and accuracy in both retrieved amplitude and phase information. In order to obtain high-accurate sample details, we propose TIE based in-focus correction technique for quantitative amplitude and phase imaging, which can locate focal plane and then retrieve both in-focus intensity and phase distributions combining with numerical wavefront extraction and propagation as well as physical image recorder translation. Certified by both numerical simulations and practical measurements, it is believed the proposed method not only captures high-accurate in-focus sample information, but also provides a potential way for fast autofocusing in microscopic system.

Abstract
Objective: To investigate the effect of occupational exposure to coal tar pitch on workers' health and metabolism. Methods: 805 workers exposed to coal tar pitch were selected as exposure group from the produce and em-ploy factory. Other people handle administrative and logistical affairs who not exposed to coal tar pitch were selected as control group. Fix-point sample of air were collected to detect the concentration of coal tar pitch. Do physical examination and questionnaire to collect workers' basic and healthy information. To detect the metabolic product of urine samples in laboratory. Results: Anomaly detection rate of the skin in exposure group is 10.61. The lung function indices (FEV1.0%) in exposure group were significantly lower than control group (P<0.05) . The monocyte count and monocyte rate in expo-sure group were significantly higher than control group (P<0.05) . The metabolic product content of PAHS in urine sam-ples is significantly higher in exposed group than control group (P<0.05) . Conclusion: The metabolic product content of polycyclic aromatic hydrocarbon is higher in exposed workers. Coal tar pitch damage workers' skin and lung function. It can cause pruritus chromatodermatosis and so on.

Abstract
ZNF750 controls epithelial homeostasis by regulating epidermal-differentiation genes, a role underscored by its pathogenic mutations in esophageal squamous cell cancers (SCCs). However, the precise role of ZNF750 in SCC cell biology remains unclear. In this study, we report that ZNF750 is exclusively deleted, mutated and underexpressed in human SCCs, and low ZNF750 expression is associated with poor survival. Restoration of wildtype, but not mutant ZNF750 protein uniquely inhibited the malignant phenotypes of SCC cells both in vitro and in vivo. Notably, ZNF750 promoted the expression of a long non-coding RNA (TINCR), which mediated both cancer-inhibition and differentiation-induction effects of ZNF750. In addition, ZNF750 potently suppressed cell migration by directly inhibiting the transactivation of LAMC2. Together, our findings characterize ZNF750 as a crucial SCC-specific suppressor and uncover its novel anticancer-associated functions.

Abstract
BACKGROUND Little is understood about of the role of coping strategies in psychological well-being (PWB) and distress for the general population and different physical and psychiatric disease groups. A thorough examination of these relationships may provide evidence for the implementation of public mental health promotion and psychiatric disease prevention strategies aimed at improving the use of positive coping approaches or addressing the causes and maintainers of distress. The present study using a structural equation modelling (SEM) approach and nationally representative data on the Canadian population investigates the relationships among PWB, distress and coping strategies and identifies major factors related to PWB for both the general population and diverse-specific disease groups. METHODS Data examined were from the Canadian Community Health Survey of Mental Health and Well-being (CCHS 1.2), a large national survey (n = 36 984). We applied exploratory factor analysis (EFA), confirmatory factor analysis and SEM to build structural relationships among PWB, distress and coping strategies in the general population. RESULTS Both SEM measurement and structure models provided a good fit. Distress was positively related to negative coping and negatively related to positive coping. Positive coping indicated a higher level of PWB, whereas negative coping was associated with a lower level of PWB. PWB was negatively related to distress. These same relationships were also found in the population subgroups. For the population with diseases (both physical and psychiatric diseases, except agoraphobia), distress was the more important factor determining subjective PWB than the person's coping strategies, whereas, negative coping had a major impact on distress in the general population. Strengths and limitations were also discussed. CONCLUSIONS Our findings have practical implications for public psychiatric disease intervention and mental health promotion. As previously noted positive/adaptive coping increased the level of PWB, whereas negative/maladaptive coping was positively related to distress and negatively related to PWB. Distress decreased the level of PWB. Our findings identified major correlates of PWB in both the general population and population subgroups. Our results provide evidence for the differential use of intervention tactics among different target audiences. In order to improve the mental health of the general population public mental health promotion should focus on strategies that reduce negative coping at a population level, whereas clinicians treating individual clients should make the reduction of distress their primary target to maintain or improve patients' PWB.

Abstract
OBJECTIVE To investigate the clinical treatment of infective endocarditis with vegetations in pregnant women and the outcomes of the gestation. METHODS Nine cases of pregnant women diagnosed as infective endocarditis with vegetations in Beijing Anzhen Hospital, Capital Medical University from January 2001 to October 2015 were enrolled in retrospective analysis. Consultations were held by doctors from department of obstetrics, anesthesiology, cardiology, cardial surgery and extracorporeal circulation to decide the individualized treatment plan for the 9 cases of pregnant women after admissions. Clinical treatments including general treatment, anti-infection treatment, cardiac surgery, and termination of pregnancy surgery were completed through collaboration among related departments. The clinical characters, therapeutic regimens, maternal and neonatal outcomes of the 9 cases were analyzed. RESULTS (1) Clinical characters: the ages of the 9 cases of pregnant women were from 25 to 36 years old. The onset gestational ages were from 19 to 36 weeks. CLINICAL SYMPTOMS fever, cough, sputum and progressive anemia were the main symptoms. Patients had cyanosis of lips, could not lie on the back or even be orthopnea, when heart failure happened. Heart murmur was audible and splenomegaly was touched in physical examination. Blood cultures were positive. Basic heart disease types: 7 cases of congenital heart diseases included 2 cases of aortic insufficiency, 1 case of mitral insufficiency, 1 case of patent ductus arteriosus, 1 case of right ventricular outflow tract stenosis and 2 cases of ventricular septal defect.Two cases of rheumatic heart diseases included 1 case of mitral stenosis, 1 case of mitral stenosis after artificial disc changed and jammed. According to endocardial vegetations attached position there were 3 cases of mitral valve vegetations, 2 cases of pulmonary valve vegetations, 3 cases of aortic vegetations and 1 case of right ventricular outflow tract neoplasm. Preoperative heart function classification: 1 case of level Ⅱ, 3 cases of level Ⅲ, 5 cases of level Ⅳ. (2) TREATMENTS: general treatment included oxygen uptake, rest in bed, cardiac strengthen and diuretic therapy, etc. Combined and adequate antibiotics were applied in anti-infection treatment according to drug sensitive test. Nine cases of pregnant women were all performed surgical treatment of heart diseases and removal of the endocardial vegetations. Caesarean sections were performed for 2 cases in second trimester and for 7 cases in last trimester. Cardiac surgery and caesarean section were operated in 6 cases at the same time among 22-34 weeks of pregnancy. Cardiac surgery were respectively operated in 2 cases 11 days and 32 days after the caesarean section at 33, 37 weeks of pregnancy. While Cardiac surgery was operated (at 26 weeks of pregnancy) before the caesarean section (at 37 weeks of pregnancy) in another 1 case. (3) Maternal and neonatal outcomes: 7 cases of pregnant women were rescued successfully, while 2 cases of pregnant women were death. Postoperative heart function classification: 1 case of level Ⅰ, 2 cases of level Ⅱ, 4 cases of level Ⅲ and 2 cases of level Ⅵ. Neonatal survivals were 6 cases including 2case of full-term infants, 4 cases of preterm infants. Stillbirth or neonatal death were 3 cases, which included 2 cases performed caesarean section in second trimester and 1 case of very low weight infant who was given up treatment by family because of severe asphyxia. Followed up periods were from 1 to 7 years with an average time of (2.0±1.6) years. Infants and young children grew and developed well during the period of follow up. CONCLUSIONS The risk is extremely high of pregnancy with infective endocarditis with vegetations. But there is still a way to save the maternal and neonatal life by using a multidisciplinary collaboration formulation and implementation of individualized treatment plan and selecting the appropriate time for heart surgery and the termination of pregnancy.

Abstract
BACKGROUND Literature supports a strong relationship between childhood maltreatment and mental illness but most studies reviewed are cross-sectional and/or use recall to assess maltreatment and are thus prone to temporality and recall bias. Research on the potential prospective impact of maltreatment reduction on the incidence of psychiatric disorders is scarce. METHOD Electronic databases and grey literature from 1990 to 2014 were searched for English-language cohort studies with criteria for depression and/or anxiety and non-recall measurement of childhood maltreatment. Systematic review with meta-analysis synthesized the results. Study quality, heterogeneity, and publication bias were examined. Initial screening of titles and abstracts resulted in 199 papers being reviewed. Eight high-quality articles met eligibility criteria. Population attributable fractions (PAFs) estimated potential preventive impact. RESULTS The pooled odds ratio (OR) between any type of maltreatment and depression was 2.03 [95% confidence interval (CI) 1.37-3.01] and 2.70 (95% CI 2.10-3.47) for anxiety. For specific types of maltreatment and depression or anxiety disorders, the ORs were: physical abuse (OR 2.00, 95% CI 1.25-3.19), sexual abuse (OR 2.66, 95% CI 1.88-3.75), and neglect (OR 1.74, 95% CI 1.35-2.23). PAFs suggest that over one-half of global depression and anxiety cases are potentially attributable to self-reported childhood maltreatment. A 10-25% reduction in maltreatment could potentially prevent 31.4-80.3 million depression and anxiety cases worldwide. CONCLUSION This review provides robust evidence of childhood maltreatment increasing the risk for depression and anxiety, and reinforces the need for effective programs and policies to reduce its occurrence.
