Abstract
Objective: To investigate the risk factors, clinical features, treatments, and prevention of pulmonary hypertensive crisis (PHC) in children with idiopathic pulmonary arterial hypertension (IPAH) undergoing cardiac catheterization. Methods: This retrospective study included 67 children who were diagnosed with IPAH and underwent cardiac catheterization between April 2009 and June 2017 in Beijing Anzhen Hospital. The medical histories, clinical manifestations, treatments, and outcomes were characterized. Statistical analyses were performed using t test, χ(2) test and a multiple Logistic regression analysis. Results: During cardiac catheterization, five children developed PHC who presented with markedly elevated pulmonary artery pressure and central venous pressure, decline in systemic arterial pressure and oxygen saturation. Heart rate decreased in 4 cases and increased in the remaining one. After the treatments including cardiopulmonary resuscitation, pulmonary vasodilator therapy, improving cardiac output and blood pressure, and correction of acidosis, 4 of the 5 cases recovered, while 1 died of severe right heart failure with irreversible PHC 3 days after operation. Potential PHC was considered in 7 other patients, whose pulmonary artery pressure increased and exceeded systemic arterial pressure, oxygen saturation decreased, and central venous pressure and vital signs were relatively stable. Univariate analysis showed that the risk factors of PHC in children with IPAH undergoing cardiac catheterization were younger age (t=3.160, P=0.004), low weight (t=4.004, P<0.001), general anesthesia (χ(2)=4.970, P=0.026), history of syncope (χ(2)=4.948, P=0.026), and WHO cardiac functional class Ⅲ or Ⅳ (χ(2)=19.013, P<0.001). Multivariate Logistic regression analysis revealed that worse WHO cardiac functional class (Wald=13.128, P<0.001, OR=15.076, 95% CI: 3.475-65.418) was the independent risk factor of PHC. Conclusions: PHC is a severe and extremely dangerous complication in children with IPAH during cardiac catheterization. WHO cardiac functional class may be associated with PHC. Integrated treatment is required for these patients. Reducing risk factors, early identification, and active treatment may help to prevent the occurrence and progression of PHC.

Abstract
Abstract:Controlled medical terminologies are increasingly becoming strategic components of various healthcare enterprises. However, the typical medical terminology can be difficult to exploit due to its extensive size and high density. The schema of a medical terminology offered by an object-oriented representation is a valuable tool in providing an abstract view of the terminology, enhancing comprehensibility and making it more usable. However, schemas themselves can be large and unwieldy. We present a methodology for partitioning a medical terminology schema into manageably sized fragments that promote increased comprehension. Our methodology has a refinement process for the subclass hierarchy of the terminology schema. The methodology is carried out by a medical domain expert in conjunction with a computer. The expert is guided by a set of three modeling rules, which guarantee that the resulting partitioned schema consists of a forest of trees. This makes it easier to understand and consequently use the medical terminology. The application of our methodology to the schema of the Medical Entities Dictionary (MED) is presented.

Abstract
Objective: To analyze the prognosis and associated risk factors of pediatric idiopathic pulmonary arterial hypertension. Methods: A total of 119 patients under 18 years of age diagnosed as idiopathic pulmonary arterial hypertension in the Pulmonary Arterial Hypertension Center in Beijing Anzhen Hospital between June 2007 and May 2017 were enrolled in this retrospective study. The clinical informations and follow-up data were collected. The endpoints of follow-up were defined as death or undergoing lung transplantation. Kaplan-Meier survival curve was used to assess the survival,and the COX risk regression model was used to analyze the prognostic risk factors. Results: The mean age at diagnosis was (5.9±4.2) years. For 92 (77.5%) patients, the main reason for visit was decreased activity with shortness of breath after exercise. Seventy patients (58.8%) were in baseline NYHA functional class Ⅲ-Ⅳ and 49 patients (41.2%) were in NYHA functional class Ⅰ-Ⅱ. The mean systolic pulmonary arterial pressure estimated by echocardiography was (90±23) mmHg (1 mmHg=0.133 kPa) . Right heart catheterization was performed in 50 patients. Hemodynamic parameters revealed that the mean pulmonary artery pressure was (66±19) mmHg. Mean right atrium pressure was (8.5±3.4) mmHg. Mean pulmonary vascular resistance index was (17±9) wood·m(2) and the mean cardiac index was (3.4±1.3)L/m(2); 100 patients (84.0%) received targeted therapy in which 55 patients (46.2%) were on monotherapy,40 patients (33.6%) were on dual therapy and 5 patients (4.2%) were on triple therapy. The mean time of follow-up was 22.0 months (0-108 months). During follow-up, 43 patients (36.1%) died and 1 patient received double-lung transplantation. Main causes of death including right heart failure, pulmonary hypertension crisis, asphyxia and massive hemoptysis. The mean survival time from diagnosis was 37.0 months,1-,2-,3-and 5-year survival rates were 86.3%, 72.2%, 51.4%and 37.8% respectively. Survival analysis showed that patients in baseline NYHA functional class Ⅰ-Ⅱ had better prognosis. COX regression analysis showed that NYHA function class, edema, increased total bilirubin and troponin concentration and the pulmonary artery and aorta diameter ratio measured by echocardiogram are risk factors of pediatric IPAH (HR=2.310, 2.723, 1.066, 1.696, 3.719, P=0.028, 0.005, 0.001, 0.024, 0.030) . While the existence of aterial septal defect or patent foramen ovale, using bosentan and phosphodiesterase inhibitors(,) dual or triple therapy were protective factors (HR=0.563, 0.559, 0.603, 0.682, 0.044, P=0.169, 0.076, 0.115, 0.258, 0.220) . In multivariate analysis only edema associated with decreased survival (HR=2.398, P=0.025) . Conclusion: Childhood idiopathic pulmonary arterial hypertension patients are seriously ill at visit. Worse cardiac function classification at visit associate with high mortality. Target therapy including using bosentan, dual or triple therapy can improve survival.

Abstract
Epithelial-mesenchymal transition (EMT) is a critical event in metastasis of colorectal cancer (CRC). Rho/ROCKs signaling has a pivotal role in orchestrating actin cytoskeleton, leading to EMT and cancer invasion. However, the underlying mechanisms for ROCKs activation are not fully understood. Here, we identified FOXM1D, a novel isoform of Forkhead box M1 (FOXM1) that has a pivotal role in ROCKs activation by directly interacting with coiled-coil region of ROCK2. FOXM1D overexpression significantly polymerizes actin assembly and impairs E-cadherin expression, resulting in EMT and metastasis in xenograft mouse model and knockdown of FOXM1D has the opposite effect. Moreover, a high FOXM1D level correlates closely with clinical CRC metastasis. FOXM1D-induced ROCKs activation could be abrogated by the ROCKs inhibitors Y-27632 and fasudil. These observations indicate that the FOXM1D-ROCK2 interaction is crucial for Rho/ROCKs signaling and provide novel insight into actin cytoskeleton regulation and therapeutic potential for CRC metastasis.

Abstract
Objective SASH1 is a member of the SH3/SAM adapter molecules family and has been identified as a new tumor suppressor and critical protein in signal transduction. An ectopic expression of SASH1 is associated with decreased cell viability of breast cancer. The aim of this study was to explore the association between SASH1 expression and the ultrasonographic features in breast cancer. Patients and methods A total of 186 patients diagnosed with breast cancer were included in this study. The patients received preoperative ultrasound examination, and the expression of SASH1 was determined using immunohistochemistry methods. Spearman’s rank correlation analysis was used to analyze the correlation between SASH1-positive expression and the ultrasonographic features. Results The positive expression of SASH1 was observed in 63 (33.9%) patients. The positive expression rate of SASH1 was significantly decreased in patients with breast cancer (63/186, 33.9%) compared with controls (P<0.001). The positive expression rate of SASH1 was significantly decreased in patients with edge burr sign (P=0.025), lymph node metastasis (P=0.007), and a blood flow grade of III (P=0.013) compared with patients without those adverse ultrasonographic features. The expression of SASH1 was negatively correlated with edge burr sign (P=0.025), lymph node metastasis (P=0.007), and blood flow grade (P=0.003) of the patients with breast cancer. Conclusion The expression of SASH1 was inversely correlated with some critical ultrasonographic features, including edge burr sign, lymph node metastasis, and blood flow grade in breast cancer, and decreased SASH1 expression appears to be associated with adverse clinical and imaging features in breast cancer.

Abstract
BACKGROUND Atopic dermatitis (AD) is a common inflammatory skin disease, concomitant with allergic reactions to allergens. However, the exact mechanisms of allergen-induced immune responses in AD are not clear. The aim of this study is to explore the role of DC-SIGN in capturing and processing glycan-containing allergens and in the subsequent DC activation and T helper cell polarization in AD patients. METHODS DC-SIGN expression on DCs from AD patients was analysed by confocal microscopy and flow cytometry. DC-SIGN binding to common allergens was determined by ELISA. Activation of monocyte-derived dendritic cells (Mo-DCs) by allergens was analysed by evaluation of pro-inflammatory cytokines production, and their impact on T-cell responses was investigated by a DC-T cell coculture. RESULTS DC-SIGN expression was higher on DCs in the lesional skin of AD patients compared with that of healthy controls and was correlated with disease severity. DC-SIGN could bind to many common allergens including house dust mite allergen (Der p2) and egg white allergen (Gal d2). Mo-DCs showed measurable expression of DC-SIGN and a concentration-dependent uptake of Der p2 and Gal d2, which was inhibited by mannan and anti-DC-SIGN Abs. Der p2 and Gal d2 induced the production of pro-inflammatory cytokines, including TNF-α and IL-6, by DCs from AD patients and facilitated Th2 and Th22 cell polarization. CONCLUSIONS Binding of common allergens by DC-SIGN on DCs may initiate allergen sensitization of AD or provoke the relapse of AD. Regulating the allergen-DC-SIGN interaction might be a promising strategy to prevent or intervene in the progress of AD.

Abstract
Objective Obesity is a metabolic disease. However, the underlying molecular mechanisms linking metabolic profiles and weight gain are largely unknown. Methods Here, we used semi‐targeted metabolomics to assay 156 metabolites selected from 25 key metabolic pathways in plasma samples from 300 non‐smoking healthy women identified from Mano‐A‐Mano, the Mexican American Cohort study. The study subjects were randomly divided into two cohorts: training (N = 200) and testing (N = 100) cohorts. Linear regression and Cox proportional hazard regression were used to assess the effect of body mass index (BMI) at baseline on metabolite levels and the effects of metabolites on significant weight gain during a 5‐year follow‐up. Results At baseline, we observed 7 metabolites significantly associated with BMI in both training and testing cohorts. They were Methyl succinate, Asparagine, Urate, Kynurenic acid, Glycine, Glutamic acid, and Serine. In further analysis, we identified 6 metabolites whose levels at baseline predicted significant weight gain during 5‐year follow‐up in both cohorts. They were Acetylcholine, Leucine, Hippuric acid, Acetylglycine, Urate, and Xanthine. Conclusions The findings establish the baseline metabolic profiles for BMI, and suggest new metabolic targets for researchers attempting to understand the molecular mechanisms of weight gain and obesity.

Abstract
To assess the potential effects of Cytotoxic T-lymphocyte antigen 4 (CTLA4) gene polymorphisms on susceptibility to gastric cardia adenocarcinoma (GCA), we genotyped four polymorphisms (rs733618 A>G, rs16840252 C>T, rs231775 G>A and rs3087243 G>A) in CTLA4 and calculated odds ratios (ORs) with the corresponding 95% confidence intervals (95% CIs) for the genotype and allele distributions between GCA cases and controls. The CTLA4 genotypes were determined by the polymerase chain reaction-ligase detection reaction (PCR-LDR) analysis in 330 GCA patients and 608 unrelated cancer-free controls. In this case-control study, there was no significant difference in the genotype and allele distributions of four CTLA4 polymorphisms between GCA patients and controls. However, haplotype association analysis indicated that compared with CTLA4 Grs733618 Crs16840252 Grs231775 Crs3087243 , CTLA4 Grs733618 Crs16840252 Ars231775 Grs3087243 and Ars733618 Crs16840252 Grs231775 Ars3087243 haplotypes conferred increased risks of GCA (OR = 6.46, 95% CI = 1.33-31.28; P = 0.012; both); however, CTLA4 Ars733618 Crs16840252 Ars231775 Grs3087243 and Ars733618 Trs16840252 Grs231775 Grs3087243 haplotypes conferred decreased risks of GCA (P = 0.001 and P = 0.011, respectively). These results highlight that the rare CTLA4 haplotypes may affect the development of GCA in the Chinese population.

Abstract
BACKGROUND AND PURPOSE Type 2 diabetes is associated with an increased risk of dementia. This study investigated the global connectivity patterns in the brains of patients with type 2 diabetes by using a functional MR imaging technique. MATERIALS AND METHODS Forty patients and 43 age-, sex-, and education-matched healthy controls underwent resting-state functional imaging in a 3T MR imaging unit. Degree centrality, a commonly used measurement of global connectivity, was computed for a full-brain exploration of the regions influenced by type 2 diabetes. We then examined the functional connectivity of each region by using the seed-based approach. Finally, voxelwise correlation analyses were performed to explore the relationship among the connectivity changes, cognitive performance, and diabetes-related variables. RESULTS Patients exhibited decreased degree centrality in the left lingual gyrus and increased centrality in the right insula and dorsal anterior cingulate cortex (corrected P < .05). The occipital network anchored in the lingual gyrus showed extensively reduced connectivity, while the network connectivity of the insula and cingulate cortex (mostly included in the salience network) was significantly elevated (corrected P < .05). Correlational analyses revealed that in the diabetic group, impaired visual memory and executive function performance were correlated with occipital hypoconnectivity, while higher fasting plasma glucose levels and better executive functioning were related to anterior cingulate cortex hyperconnectivity (all corrected P values < .05). Similar effects were not detected in the controls. CONCLUSIONS This preliminary study shows that network connectivity is altered in patients with type 2 diabetes, which may provide critical insight into the neural substrate of diabetes-related cognitive decline.

Abstract
BACKGROUND Primary adenosquamous carcinoma (ASC) of the lung is rare and its biological behavior has not yet been thoroughly described. The aim of this study was to analyze the clinicopathological characteristics and prognostic factors associated with ASC. MATERIALS Clinical records of patients with ASC of the lung who underwent surgery between October 2008 and December 2014 in a single institution were retrospectively reviewed. RESULTS A total of 205 patients were identified. Patients with balanced structural components had significantly better prognosis than those with squamous (p = 0.014) or adenomatous (p < 0.001) predominance, and those with N0, N1, and N2 ASC (N0 vs. N1 [ p = 0.031] and N1 vs. N2 [p = 0.037], respectively), or stage I, II and IIIA ASC (stage I vs. II [p = 0.021] and stage II vs. IIIA [p = 0.007], respectively) had significant differences with respect to overall survival (OS). Multivariate analysis identified structural components (p = 0.011), tumor, node and metastasis (TNM) status (p < 0.001), and adjuvant chemotherapy (p = 0.008) as significantly prognostic factors for OS, and structural components (p = 0.030), TNM stage (p < 0.001) and adjuvant chemotherapy (p = 0.005) as the corresponding variables for disease-free survival. CONCLUSIONS A balanced structure between adenomatous and squamous components in patients with primary ASC of the lung was associated with better prognosis.

Abstract
OBJECTIVE The incidence of missed miscarriage has been increasing during the past decade in China and the etiology of about half of the cases remains unclear. Exposure to phthalates has been considered as a risk factor. The aim of this paper is to assess the association between exposure to phthalates and missed miscarriage. PATIENTS AND METHODS A case-control study was performed including 150 cases of missed miscarriage and 150 matched controls with normal pregnancies. The levels of phthalate exposure were compared between the two groups by measuring 13 phthalate metabolites in urine samples. Blood samples were collected for serum hormone measurement to assess the relationship between serum hormone level and phthalate exposure. RESULTS The urinary levels of metabolites of di-(2-ethylhexyl) phthalate (DEHP) and dimethyl phthalate (DMP) were significantly higher in the cases than in the controls. A strong dose-response relationship was observed between urinary metabolite levels and the odds of missed miscarriage. Monomethyl phthalate (MMP), a metabolite of DMP, and mono-2-ethylhexyl phthalate (MEHP), a metabolite of DEHP, each had significant negative correlation with maternal serum hormone levels. CONCLUSIONS In the current study, exposure to DEHP and DMP was found to be associated with missed miscarriage. Interruption of hormone synthesis by DMP and DEHP metabolites represents a plausible mechanism of phthalate reproductive toxicity.

Abstract
The role of autotransplantation in end-stage hepatic alveolar echinococcosis (AE) is unclear. We aimed to present our 15-case experience and propose selection criteria for autotransplantation. All patients were considered to have unresectable hepatic AE by conventional resection due to critical invasion to retrohepatic vena cava, hepatocaval region along with three hepatic veins, and the tertiary portal and arterial branches. All patients successfully underwent ex vivo extended right hepatectomy and autotransplantation without intraoperative mortality. The median autograft weight was 706 g (380-1000 g); operative time was 15.5 hours (11.5-20.5 hours); and anhepatic time was 283.8 minutes (180-435 min). Postoperative hospital stay was 32.3 days (12-60 days). Postoperative complication Clavien-Dindo grade IIIa or higher occurred in three patients including one death that occurred 12 days after the surgery due to acute liver failure. One patient was lost to follow-up after the sixth month. Thirteen patients were followed for a median of 21.6 months with no relapse. This is the largest reported series of patients with end-stage hepatic AE treated with liver autotransplantation. The technique requires neither organ donor nor postoperative immunosuppressant. The early postoperative mortality was low with acceptable morbidity. Preoperative precise assessment and strict patient selection are of utmost importance.
