Abstract
Nanotherapies, valued for their high efficacy and low toxicity, frequently serve as antitumor treatments, but do not readily penetrate deep into tumor tissues and cells. Here we developed an improved tumor-penetrating peptide (TPP)-based drug delivery system. Briefly, the established TPP iNGR was modified to generate a linear NGR peptide capable of transporting nanotherapeutic drugs into tumors through a CendR pathway-dependent, neuropilin-1 receptor-mediated process. Although TPPs have been reported to reach intended tumor targets, they often fail to penetrate cell membranes to deliver tumoricidal drugs to intracellular targets. We addressed this issue by harnessing cell penetrating peptide technology to develop a liposome-based multibarrier-penetrating delivery system (mbPDS) with improved synergistic drug penetration into deep tumor tissues and cells. The system incorporated doxorubicin-loaded liposomes coated with nona-arginine (R9) CPP and cyclic iNGR (CRNGRGPDC) molecules, yielding Lip-mbPDS. Lip-mbPDS tumor-targeting, tumor cell/tissue-penetrating and antitumor capabilities were assessed using CD13-positive human fibrosarcoma-derived cell (HT1080)-based in vitro and in vivo tumor models. Lip-mbPDS evaluation included three-dimensional layer-by-layer confocal laser scanning microscopy, cell internalization/toxicity assays, three-dimensional tumor spheroid-based penetration assays and antitumor efficacy assays conducted in an animal model. Lip-mbPDS provided enhanced synergistic drug penetration of multiple biointerfaces for potentially deep tumor therapeutic outcomes.

Abstract
Perfluorinated compounds, especially Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), are widely detected in water environments in China. Considering the potential health risks of drinking water exposure routes, PFOA and PFOS have been added to the water quality reference index of the newly issued "Standards for Drinking Water Quality (GB5749-2022)", with limit values of 40 and 80 ng/L, respectively. This study analyzed and discussed the relevant technical contents for determining the limits of the hygiene standard, including the environmental existence level and exposure status of PFOA and PFOS, health effects, derivation of safety reference values, and determination of hygiene standard limits. It also proposed prospects for the future direction of formulating drinking water standards.

Abstract
Acidic postconditioning by transient CO2 inhalation applied within minutes after reperfusion has neuroprotective effects in the acute phase of stroke. However, the effects of delayed chronic acidic postconditioning (DCAPC) initiated during the subacute phase of stroke or other acute brain injuries are unknown. Mice received daily DCAPC by inhaling 5%/10%/20% CO2 for various durations (three cycles of 10- or 20-min CO2 inhalation/10-min break) at days 3-7, 7-21, or 3-21 after photothrombotic stroke. Grid-walk, cylinder, and gait tests were used to assess motor function. DCAPC with all CO2 concentrations significantly promoted motor functional recovery, even when DCAPC was delayed for 3-7 days. DCAPC enhanced the puncta density of GAP-43 (a marker of axon growth and regeneration) and synaptophysin (a marker of synaptogenesis) and reduced the amoeboid microglia number, glial scar thickness and mRNA expression of CD16 and CD32 (markers of proinflammatory M1 microglia) compared with those of the stroke group. Cerebral blood flow (CBF) increased in response to DCAPC. Furthermore, the mRNA expression of TDAG8 (a proton-activated G-protein-coupled receptor) was increased during the subacute phase of stroke, while DCAPC effects were blocked by systemic knockout of TDAG8, except for those on CBF. DCAPC reproduced the benefits by re-expressing TDAG8 in the peri-infarct cortex of TDAG8-/- mice infected with HBAAV2/9-CMV-TDAG8-3flag-ZsGreen. Taken together, we first showed that DCAPC promoted functional recovery and brain tissue repair after stroke with a wide therapeutic time window of at least 7 days after stroke. Brain-derived TDAG8 is a direct target of DCAPC that induces neuroreparative effects.

Abstract
Objective: To establish the norms and clinical application standards of mass spectrometry method to measure vitamin D in capillary blood. Methods: Following the "Province-City-Hospital" sampling procedure, a cross-sectional sample of 1 655 healthy children under 7 years of age were recruited from 12 provinces, autonomous regions, or municipalities in China from November 2020 to December 2021. Both venous and capillary blood samples from the same individual were collected, for which serum 25(OH)D levels were measured by high-performance liquid chromatography-mass spectrometry (HPLC-MS/MS) method. Pearson correlation analysis and linear regression analysis were used to detect the correlation and determine a correction algorithm. The agreement was analyzed using Bland-Altman plot and Kappa statistic. The sensitivity and specificity were evaluated using receiver operating characteristic (ROC) curve method. Results: Venous and capillary 25(OH)D levels of 1 655 healthy children under 7 years of age were 74.25 (59.50, 92.00) and 68.75 (54.44, 86.25) nmol/L, respectively, showed a significant difference(Z=22.14, P<0.001) as well as a highly significant correlation between venous and capillary 25(OH)D levels(r=0.95, P<0.001). Linear regression analysis was then performed to determine the correction algorithm: lg(corrected capillary 25(OH)D)=0.13+0.95×lg(capillary 25(OH)D)(R2=0.90,P<0.001). The deviation between venous and corrected capillary 25(OH)D levels was (0.50±17.50) nmol/L, a difference value that did not reach statistical significance (P>0.05). The cut-off values of capillary blood 25(OH)D values 30.00, 50.00, 75.00 nmol/L corresponding to venous blood 25(OH)D values were 26.59, 45.56, and 69.84 nmol/L, respectively. Good consistency was observed between venous and corrected capillary 25(OH)D levels in clinical diagnosis (Kappa value 0.68-0.81). Corrected capillary 25(OH)D showed a high clinically predictive value (area under curve 0.97-0.99,sensitivity 0.72-0.92,specificity 0.89-0.99). Conclusion: The standardized capillary HPLC-MS/MS method can be used to detect 25(OH)D levels in children clinically.

Abstract
Objective: To explore current vitamin D status and influential factors of vitamin D deficiency and insufficiency among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China. Methods: According to the "province-city-hospital" sampling technical route, a total of 1 531 healthy children under 7 years of age were sampled from 11 provinces, autonomous regions or municipalities in China by the cluster random sampling method from November 2020 to November 2021. The demographic information, family conditions, behavior and living habits and feeding behaviors were collected using unified questionnaire. Serum 25-hydroxyvitamin D(25(OH)D) levels were measured by liquid chromatography-tandem mass spectrometry. Serum 25(OH)D<30 nmol/L was considered deficient and 30-50 nmol/L was considered insufficient. With 25(OH)D≤50 nmol/L as the dependent variable, multivariate Logistic regression was applied to analyze the association between vitamin D deficiency and insufficiency and potential influential factors. Results: The prevalence of vitamin D deficiency and insufficiency among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China was 14.0% (215/1 531), 3.8% (25/664) and 21.9% (190/867) in 0-<3 and 3-<7 of age years, respectively. Compared to children aged 0-<3 years, children aged 3-<7 years had a 2.6-fold increased risk of vitamin D deficiency and insufficiency (OR=3.60, 95%CI 1.93-6.72, P<0.001). Frequent sunlight exposure (OR=0.46, 95%CI 0.29-0.73, P=0.001), vitamin D supplementation (sometimes, OR=0.33, 95%CI 0.21-0.51, P<0.001; daily, OR=0.20, 95%CI 0.11-0.36, P<0.001) and infant formula intake(4-7 times per weeks, OR=0.43, 95%CI 0.28-0.68, P<0.001) were protective factors for vitamin D deficiency and insufficiency. Conclusion: Vitamin D deficiency and insufficiency are common among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China, which is affected by age, sunlight exposure, vitamin D supplementation and infant formula intake.

Abstract
Objective: To evaluate the nutritional status by the Controlling Nutritional Status (CONUT) score and its association with the long-term prognosis in patients with acute heart failure (AHF). Methods: This prospective monocentric study consecutively enrolled patients admitted to our hospital for AHF from April 2012 to May 2016. Patients were divided into 3 groups based on the CONUT score at admission: normal (0-1), mild malnutrition (2-4) and moderate-severe malnutrition (5-12) groups. Baseline information was obtained and recorded within 24 hours after admission. All patients were followed up every 3 months by outpatient visit or telephone call until March 2019. The primary endpoint was all-cause mortality. The Kaplan-Meier survival curves and log-rank test were used to compare all-cause mortality between groups. Variables showing statistical significance in the univariate analysis were incorporated into multivariate Cox regression model to analyze the independent risk factors for all-cause mortality after discharge. Results: A total of 396 patients were enrolled in this study, including 114 patients with normal nutritional status, 200 patients with mild malnutrition and 82 patients with moderate-severe malnutrition. One hundred and fifty-eight patients died during a median follow-up of 34 (18, 46) months. The mortality was 32.4% (37/114), 39% (78/200) and 52.4% (43/82) in normal, mild malnutrition and moderate-severe malnutrition groups, respectively. The mortality was significantly higher in the moderate-severe malnutrition group than in normal nutrition group (P<0.05). However, there was no significant difference in mortality between normal and mild malnutrition group as well as between mild and moderate-severe malnutrition group (both P>0.05). Kaplan-Meier curves indicated that patients with high CONUT score group was at higher risk of all-cause mortality compared with those with low CONUT score (P=0.002). Cox proportional hazard analyses showed that the risk of all-cause mortality of moderate-severe malnutrition group was significantly higher than that of normal nutrition group (HR =1.648, 95%CI 1.021-2.660, P=0.041). Conclusions: The CONUT score of patients with AHF at admission is associated with the long-term prognosis. High CONUT score is an independent risk factor for all-cause mortality in AHF patients after discharge.

Abstract
1. The aim of this study was to explore the effects of acute heat stress on serum hormone levels and the expression of genes and proteins related to the unfolded protein response (UPR) pathway and apoptotic process in the liver of broilers.2. A total of 144 Arbor Acres broilers (35-d-old) were randomly allocated to 4 different environmental-controlled chambers for acute heat exposure. The temperature of the 4 environmental chambers was adjusted to 26°C (control), 29°C, 32°C, and 35°C within 1 h, respectively. The blood and liver samples were collected after 6 h of constant heat exposure at set temperatures.3. The results showed that 6 h of acute heat stress increased serum hormone levels and up-regulated the expression of heat shock protein. The endoplasmic reticulum (ER) stress markers, GRP78 and GRP94, in the liver of broilers were significantly upregulated at the mRNA and protein levels. The PERK, IRE1, and XBP1 genes, which are involved in the unfolded protein response signalling, were significantly up-regulated at the mRNA levels. However, other pro-apoptotic genes showed no significant changes in the liver of broiler chickens in all groups except for upregulation of the anti-apoptotic gene BCL-xl.4. The results suggested that broilers have tolerance to acute heat stress to a certain extent. The UPR activation can alleviate ER stress and further prevent apoptosis in the liver of broilers under short-term exposure to high ambient temperatures.

Abstract
Objective: To analyze the clinical data of pregnant women complicated with cardiovascular disease in our center in the past 10 years, and to explore the trend of incidence, clinical diagnosis, and treatment of the disease. Methods: Clinical data of pregnant women with cardiovascular disease who delivered in Beijing Anzhen Hospital, Capital Medical University from 2010 to 2019 were collected and analyzed retrospectively. According to the time of the establishment of multidisciplinary team (MDT) in the center, the pregnant women were divided into the first 5-year group (2010-2014) and the second 5-year group (2015-2019). The general data, the composition of pregnancy complicated with cardiovascular disease and the changes of maternal and infant outcomes of the two groups were analyzed. Results: (1) During 2010-2019, there were 2 267 cases of pregnancy complicated with cardiovascular disease (836 cases in the first 5-year group and 1 431 cases in the second 5-year group), with a total incidence of 10.2% (2 267/22 334). Among all kinds of cardiovascular diseases, arrhythmia (41.0%, 930/2 267) and congenital heart disease (38.2%, 865/2 267) were more common. (2) There were 212 cases (25.4%, 212/836) and 426 cases (29.8%, 426/1 431) classified as Ⅲ or Ⅳ by modified WHO cardiovascular risk classification in the first 5-year group and the second 5-year group, respectively, and the difference was statistically significant (χ²=5.076,P=0.024). Among all kinds of cardiovascular diseases, there were 111 cases (13.3%, 111/836) and 159 cases (11.1%, 159/1 431) with valvular disease in the first 5-year group and the second 5-year group, respectively. The change of the component ratio was -16.5% (the difference was significant when the absolute value of change>10%), showing a significant decreasing trend. Aortic disease was found in 16 cases (1.9%, 16/836) and 56 cases (3.9%, 56/1 431), respectively, with a significant upward trend of 105.3%. (3) The mortality rate of pregnant women with cardiovascular disease was 1.0% (22/2 267), and 1.2% (10/836) and 0.8% (12/1 431) in the first 5-year grouop and the second 5-year group, respectively. There was no significant difference between the two groups (χ²=0.702,P=0.402). ICU occupancy rates in the first 5-year group and the second 5-year group were 25.6% (214/836) and 20.7% (296/1 431), respectively, and the difference between the two groups was statistically significant (χ²=7.306,P=0.007). There were no significant differences in cesarean section rate, mortality rate and incidence of adverse events between the two groups of pregnant women, and there were no significant differences in birth weight, preterm birth rate, mortality rate and asphyxia rate between the two groups of newborns (all P>0.05). Conclusions: Pregnancy complicated with cardiovascular disease is a common cause of adverse obstetric outcomes. There are various types of specific cardiovascular diseases, and the prognosis varies greatly. In recent years, the disease composition ratio has changed, and the severity and complexity of diseases have increased. Hierarchical management, MDT and individual management could improve the treatment level and reduce adverse outcomes.

Abstract
Objective: To explore the association between sleep duration, sleep quality and the prevalence of hypertension in the elderly aged 65 years and above. Methods: This study was conducted among the elderly in communities in Yiwu, China from April to July, 2019, and participants were recruited through physical examination in the hospital. Face-to-face interview was performed to obtain basic information. Sleep duration and sleep quality were evaluated by Pittsburgh Sleep Quality Index (PSQI). Associations between sleep duration, sleep quality and hypertension were evaluated by multivariate logistic regression analysis. Results: A total of 3 169 elderly persons, aged ≥65 years old, were included in the study. The overall prevalence of hypertension was 50.8%. The elderly with very poor sleep quality and short sleep duration accounted for 22.4% and 28.5%, respectively. After adjusting for demographic characteristics, socioeconomic status, lifestyle and health status, the OR of hypertension for the elderly with very poor sleep quality was 1.42 (95%CI: 1.12-1.80) compared with those with very good sleep quality. Compared with the elderly with sleep duration of 6-7 h a night, the OR of hypertension for those with sleep duration <6 h was 1.37 (95%CI: 1.15-1.65). As the sleep quality decreased, the risk for hypertension increased. An U-shaped association was found between sleep duration and risk of hypertension. Subgroup analyses showed that this association existed in both men and women, but only significant in the elderly aged <75 years. Conclusion: Poor sleep quality and short sleep duration were associated with risk for hypertension in the elderly.

Abstract
Objective: To study the effect of MYD88 L265P mutation on the expression of PD-L1 in tumor cells and tumor microenvironment in diffuse large B-cell lymphoma (DLBCL), and to provide theoretical basis for immunotherapy for patients. Methods: Multiplex ligation-dependent probe amplification (MLPA) was used to detect the frequency of MYD88 L265P mutation in 72 cases of DLBCL diagnosed by pathologists in Cancer Hospital of Chinese Academy of Medical Sciences from August 2008 to May 2010. Expression of PD-L1 in tumor cells and tumor microenvironment in all samples was evaluated using PD-L1 (22C3) and PD-L1 (SP142) with Ventana automatic immunohistochemical (IHC) platform. The relationship between MYD88 L265P mutation and the expression of PD-L1 in DLBCL tumor cells and tumor microenvironment was assessed. Results: Of the 72 cases of DLBCL, MYD88 L265P mutation was detected in 15 (20.8%) cases. Nine cases with JAK2 amplification were excluded, and the remaining 63 cases of DLBCL were divided into MYD88 L265P mutant group (n=14) and MYD88 L265P wild-type group (n=49). IHC results showed that among the 14 cases of MYD88 L265P mutant groups, PD-L1 (22C3) was positive in 7 cases (7/14) of tumor cells and PD-L1 (SP142) was positive in 4 cases (4/14) of tumor microenvironment. Among the 49 cases of MYD88 L265P wild-type group, 9 cases (18.4%) were positive for PD-L1 (22C3) in tumor cells, and 38 cases (77.6%) were positive for PD-L1(SP142) in tumor microenvironment. In addition, among the 16 cases with PD-L1(22C3) expression in tumor cells, only 2 of the 7 cases with MYD88 L265P mutation were positive for PD-L1 (SP142) in tumor microenvironment. All 9 cases with wild-type MYD88 L265P were positive for PD-L1 (SP142) in tumor microenvironment. Statistical analysis showed that the expression level of PD-L1 (22C3) in tumor cells in the MYD88 L265P mutant group was significantly higher than that in the MYD88 L265P wild-type group (P=0.017). The expression level of PD-L1 (SP142) in tumor microenvironment in the MYD88 L265P mutant group was significantly lower than that in the MYD88 L265P wild-type group (P=0.001). Conclusions: MYD88 L265P mutation may play an important role in the regulation of PD-L1 expression in DLBCL tumor cells and tumor microenvironment. Further studies will provide a theoretical basis for immunotherapy of DLBCL patients with MYD88 L265P mutation.

Abstract
Objective: To observe the clinical effect of treatment with follicular unit extraction (FUE) and transplantation in treating cicatricial alopecia. Methods: The retrospective cohort study was conducted. From January 2012 to January 2018, 56 patients (36 males and 20 females, aged (25±9) years, 1% to 30% alopecia area of the whole scalp area) who met the inclusion criteria visited the outpatient department of the First Affiliated Hospital of Xi'an Medical University. They were treated with FUE transplantation. The procedure of treatment was performed through the preoperative planning, follicular extraction, follicular preparation, punching recipient site and hair transplantation. The survival rate of hair and density of survived hair were calculated, hair growth and complication were observed. The evaluation was conducted through questionnaire survey by 4 levels: very satisfied, satisfied, not satisfied, and not at all satisfied with effects. Results: After a follow-up of 9 to 24 months, the survival rate of hair in 56 patients was (70±9)%, and the density of survived hair was (35±8) roots/cm2. In the evaluation of the curative effect after the first stage surgery, 34 cases (60.7%) were very satisfied, 16 cases (28.6%) were satisfied, and 6 cases (10.7%)thought the treatment was effective but not satisfied. Six unsatisfactory patients and 16 satisfactory patients underwent the second-stage transplantation, with 19 (86.4%) of them being very satisfied and 3 cases (13.6%) satisfied after the second-stage operation. None of the patients underwent the third-stage surgery. The transplanted hairs grew naturally, and there were no serious complications in all cases. Conclusions: FUE transplantation can effectively treat and improve cicatricial alopecia with less trauma, fewer complication, no scar in the donor site and rapid post-operative recovery, so it is worthy of clinical promotion.

Abstract
Objective: To analyze the clinical features, genetic characteristics, treatment and follow-up results of patients with hydrocephalus caused by methylmalonic acidemia combined with homocysteinuria, and to discuss the optimal strategies for assessing and treating such patients. Methods: From January 1998 to December 2020, 76 patients with hydrocephalus due to methylmalonic acidemia combined with homocysteinuria in the Department of Pediatrics in 11 hospitals including Peking University First Hospital were diagnosed by biochemical, genetic analysis and brain imaging examination. The patients were divided into operation-group and non-operation-group according to whether they underwent ventriculoperitoneal shunt. The clinical features, laboratory examinations, genotype, and follow-up data were retrospectively analyzed. Data were compared between the two groups using rank sum test, and categorical data were compared using χ2 test. Results: Among the 76 patients (51 male, 25 female), 5 were detected by newborn screening, while 71 were diagnosed after clinical onset, 68 cases (96%) had early-onset, 3 cases (4%) had late-onset. The most common clinical manifestations of 74 cases with complete data were psychomotor retardation in 74 cases (100%), visual impairment in 74 cases (100%), epilepsy in 44 cases (59%), anemia in 31 cases (42%), hypotonia or hypertonia in 21 cases (28%), feeding difficulties in 19 cases (26%) and disturbance of consciousness in 17 cases (23%). Genetic analysis was performed in 76 cases, all of whom had MMACHC gene variations, including 30 homozygous variations of MMACHC c.609G>A. The most common variations were c.609G>A (94, 62.7%), followed by c.658_660del (18, 12.0%), c.567dupT (9, 6.0%) and c.217C>T (8, 5.3%). Therapy including cobalamin intramuscular injection, L-carnitine and betaine were initiated immediately after diagnosis. A ventriculoperitoneal shunt operation was performed in 41 cases (operation group), and 31 patients improved after metabolic intervention (non-operation group). There was no significant difference in the age of onset, the age of diagnosis, the blood total homocysteine, methionine, and urinary methylmalonic acid concentration between the two groups (all P>0.05). The symptoms of psychomotor development, epilepsy, and visual impairments improved gradually after a long-term follow-up in the operation group. Conclusions: Hydrocephalus is a severe complication of methylmalonic acidemia combined with homocysteinuria. The most common clinical manifestations are psychomotor retardation, visual impairment, and epilepsy. It usually occurs in early-onset patients. Early diagnosis and etiological treatment are very important. Hydrocephalus may improve after metabolic intervention in some patients. For patients with severe ventricular dilatation, prompt surgical intervention can improve the prognosis.

Abstract
Increased expression of the Nod-like receptor pyrin containing 3 (NLRP3) inflammasome and proinflammatory cytokines is associated with depressive behaviors. This study aimed to explore potential differences in neuroinflammation associated with stress resilience, as well as associated changes in autophagy, in a mouse model of chronic unpredictable mild stress (CUMS). Animals were classified as CUMS resilient or CUMS susceptible based on performance on behavioral tests following the CUMS protocol. Then the expression levels of NLRP3 inflammasome-related proteins, interleukin-1 beta (IL-1β), and Beclin 1 in stress-related brain regions (e.g., prefrontal cortex and hippocampus) were determined. Results showed that stress exposure triggered significant NLRP3 inflammasome increase in CUMS susceptible mice but not in CUMS resilient mice. These changes were accompanied by altered IL-1β and Beclin 1 expression levels. These findings indicate that stress resilience is associated with reduced pro-inflammatory signaling and autophagy activation, and suggest that therapeutically targeting these pathways might promote stress resilience.

Abstract
OBJECTIVE To establish a diagnostic model of idiopathic central precocious puberty on the basis of transrectal pelvic ultrasound and basal gonadotropin. METHODS A total of 669 girls with Tanner breast development stage II were enrolled in this study from January 2015 to December 2018. The participants were divided into the ICPP group and the premature thelarche group. We analyzed various variables, including age at initial diagnosis, basal luteinizing hormone levels, the long diameter of the uterus, the transverse diameter of the uterus, the anterior-posterior diameter of the uterus, the volume of the uterus, maximum ovarian diameter, average ovarian volume, maximum ovarian volume, number of follicles (≥4 mm), maximum follicular diameter, endometrial thickness, and vaginal wall thickness. RESULTS The following diagnostic model was established: Y=-14.123 + 0.630 × age at initial diagnosis + 1.119 × transverse diameter of the uterus + 1.278 × anterior-posterior diameter of the uterus + 0.637 × average ovarian volume + 1.316 × maximum ovarian diameter + 0.146 ×number of follicles ≥4 mm + 2.925 × endometrial thickness + 0.559 × basal luteinizing hormone value. The area under curve was 0.922, sensitivity was 84.9%, and specificity was 86.2%. CONCLUSION Basal LH levels and transrectal pelvic ultrasound should be applied together to improve the accuracy of diagnosis in ICPP.

Abstract
Overexpression of breast cancer resistance protein (BCRP) plays a crucial role in the acquired multidrug resistance (MDR) in breast cancer. The elucidation of molecular events that confer BCRP-mediated MDR is of major therapeutic importance in breast cancer. Epithelial cell adhesion molecule (EpCAM) has been implicated in tumor progression and drug resistance in various types of cancers, including breast cancer. However, the role of EpCAM in BCRP-mediated MDR in breast cancer remains unknown. In the present study, we revealed that EpCAM expression was upregulated in BCRP-overexpressing breast cancer MCF-7/MX cells, and EpCAM knockdown using siRNA reduced BCRP expression and increased the sensitivity of MCF-7/MX cells to mitoxantrone (MX). The epithelial-mesenchymal transition (EMT) promoted BCRP-mediated MDR in breast cancer cells, and EpCAM knockdown partially suppressed EMT progression in MCF-7/MX cells. In addition, Wnt/β-catenin signaling was activated in MCF-7/MX cells, and the inhibition of this signaling attenuated EpCAM and BCRP expression and partially reversed EMT. Together, this study illustrates that EpCAM upregulation by Wnt/β-catenin signaling induces partial EMT to promote BCRP-mediated MDR resistance in breast cancer cells. EpCAM may be a potential therapeutic target for overcoming BCRP-mediated resistance in human breast cancer.

Abstract
Thermo-oxidative process leads to the structure damage of elastomers, such as the scission of main chains and destruction of crosslinks. The problem that damaged structure brings about the deterioration of mechanical properties has not been solved by the conventional anti-aging methods. Inspired by self-healing process, a structure recovery strategy for recovering the damaged structure induced by thermo-oxidative process is proposed, which endows elastomers with superior thermo-oxidative resistance. The high reactivity between 1,3-diisopropenylbenzene and free radicals realizes high recovery efficiency (from 83% to 118%); the changes in topology structure during recovery process make much more rubber chains bear external stress and improve mechanical properties significantly (from 18.5 to 29.6 MPa). This work paves the way for the development of elastomers with superior thermo-oxidative resistance, meanwhile this work is helpful to push the theoretical research of self-healing to practical application.

Abstract
OBJECTIVE The present study aimed to investigate the clinical significance and prognostic value of LINC01793 in OSCC patients, and to explore its role in the modulation of OSCC development. METHODS LINC01793 expression was analyzed in 80 cases of OSCC patients and SCC9, SCC25, Cal27, and HN6 cell lines by qRT-PCR. The association of LINC01793 expression with clinicopathological features and prognosis in OSCC patients was analyzed. The effects of LINC01793 on cell proliferation, cell cycle, migration, and invasion of SCC9 and Cal27 cells were detected by MTT, flow cytometry, and Transwell assays in vitro, respectively. RESULTS LINC01793 level was upregulated in cancer tissues and cell lines of OSCC, and its expression was increased in cancer tissues from patients with lymph node metastasis. ROC curve for LINC01793 expression and lymph node metastasis revealed a significant AUC of 0.84 (95 % CI: 0.75-0.93), with 76.51 % sensitivity and 83.69 % specificity. Moreover, high LINC01793 level was positively correlated with T category, TNM stage, lymph node metastasis, and local recurrence. OSCC patients with high level of LINC01793 was followed by low overall survival rate, and LINC01793 expression was an independent prognostic indicator for overall survival in patients with OSCC. Functionally, cell proliferation, invasion and migration of SCC9 and Cal27 cells were decreased after knockdown of LINC01793. Consistently, silence of LINC01793 induced G0/G1 cell cycle arrest in OSCC cells. CONCLUSION High LINC01793 level is correlated with adverse clinicopathological features and poor prognosis of patients with OSCC. LINC01793 act as an oncogenic role in the development of OSCC.

Abstract
Objective: To summarize the clinical characters and pregnancy outcome in pregnant women with history of atherosclerotic cardiovascular disease (ASCVD). Methods: A total of 14 pregnant women with pre-existing ASCVD admitted to Beijing Anzhen Hospital from October 2013 to May 2020 were enrolled as subjects, whose ASCVD disease status, clinical manifestations, treatment and pregnancy outcomes were collected and retrospectively analyzed. Results: The age of subjects at diagnosis of ASCVD was (31±7) years old. The main intervention before pregnancy was revascularization (10 cases), and the rest 4 cases were treated with medicine. The age of subjects at pregnancy was (36±5) years old. A total of 12 cases had risk factors of ASCVD. In early stages of pregnancy, there were 1 case with cardiac function level Ⅲ and 1 with cardiac function level Ⅳ. Abnormal ventricular wall motion and ventricular aneurysm formation were determined in 3 cases by echocardiography, one of which was complicated with moderate left ventricular ejection fraction impairment. Abnormal ST segment in 4 cases and sinus tachycardia in 1 case were found by electrocardiogram. Troponin (TNI) increased in 1 case. The serum low density lipoprotein cholesterol level (LDL-C) of these pregnant women at early stages of pregnancy was (2.3±1.0) mmol/L. A total of 9 pregnant women entered later stages of pregnancy, 1 of whom had chest tightness after slight activity. There were 4 cases with excessive weight gain and 2 cases with insufficient weight gain during pregnancy, and there were 1 case with cardiac function level Ⅲ and 1 case with mild impaired left heart function. The average level of LDL-C was (2.6±0.6) mmol/L in 5 pregnant women at their later stages of pregnancy. The main treat measures included anti-platelet therapy (aspirin, 75-100 mg/d) and healthy lifestyle interventions. Five pregnant women terminated their pregnancy at the early stage of pregnancy, and 9 full-term pregnant women underwent hysterotomy with intraoperative blood loss of 180-800 ml. Adverse cardiac events occurred in 2 cases and gestational diabetes was diagnosed in 3 cases during pregnancy, among which 2 cases were complicated with chronic hypertension and preeclampsia. The weight of 9 live newborns was (3 102±647) g, among which 2 were smaller than gestational age and 1 was of low birth weight. Conclusions: Women with established ASCVD before preynancy have risk of adverse cardiac events in pregnancy. Strengthening the management of high risk factors in pregnancy is conducive to achieving a good pregnancy outcome.

Abstract
We report a novel plastic deformation mechanism of bulk metallic glass composites (BMGCs) containing metastable β-Ti dendrites. Plastic deformation of the BMGCs beyond the ultimate tensile strength is mediated by cooperative shear events, which comprise a shear band in the glassy matrix and a continuous ω-Ti band with a thickness of ∼10 nm in the β-Ti dendrite. The cooperative shear leads to serrated shear avalanches. The formation of narrow ω-Ti bands is caused by high local strain rates during the cooperative shear. The cooperative shear mechanism enriches the deformation mechanisms of BMGCs and also deepens the understanding of ω-Ti formation.

Abstract
PURPOSE To explore FGF1 and miR-143-3p expression in hepatocellular carcinoma (HCC) cells and its related mechanisms. METHODS Eighty-two HCC patients treated at our hospital from January 2018 to January 2019 were enrolled as Group A, while further 80 healthy people undergoing physical examinations during the same time period were enrolled as Group B. HCC cells and normal human liver cells were purchased, with HepG2 and SMMC-7721 cells transfected with pcDNA3.1-FGF1, si-FGF1, NC, miR-143-3p-inhibitor and miR-143-3p-mimics. FGF1 and miR-143-3p expression was detected by qRT-PCR. The expression of N-cadherin, vimentin, Snail, Slug, E-cadherin and γ-catenin was detected by Western Blotting (WB). Cell proliferation was detected by MTT assay. Cell invasion was detected by Transwell. Cell apoptosis was detected by flow cytometry (FCM). RESULTS FGF1 was highly expressed but miR-143-3p was poorly expressed in HCC cells. Areas under the curves (AUCs) of the two indicators were > 0.8. The indicators were correlated with the age, gender, tumor invasion, degree of differentiation, tumor location and TNM staging of the patients. Silencing FGF1 and overexpressing miR-143-3p could promote cell apoptosis, inhibit cell growth, cell epithelial-mesenchymal transition (EMT) and the expression of N-cadherin, vimentin, Snail and Slug, and increase the expression of E-cadherin and γ-catenin. Dual luciferase reporter gene assay (DLRGA) confirmed that FGF1 and miR-143-3p had a targeted relationship. The rescue experiment showed that the proliferation, invasion and apoptosis of HepG2 and SMMC-7721 cells in the miR-143-3p-mimics+pcDNA3.1-FGF1 and miR-143-3p-inhibitor+Si-FGF1 groups were not different from those in the miR-NC group. CONCLUSION Inhibiting FGF1 can upregulate miR-143-3p-mediated Hedgehog signaling pathway, and affect cells' EMT, proliferation and invasion, so FGF1 is expected to become a potential therapeutic target for HCC.

Abstract
The present study was conducted to determine the impact of dietary energy and protein concentrations and lipid sources on growth performance and carcass traits of Pekin ducks. In Exp. 1, 15-day-old ducks (6 replicate pens, 60 ducks/pen) were randomly assigned to 4 dietary treatments with different metabolizable energy (ME) and crude protein (CP) concentrations (2,850 kcal/kg and 16%, 2,950 kcal/kg and 16.5%, 3,050 kcal/kg and 17.0%, and 3,150 kcal/kg and 17.5%) based on body weight (BW). In Exp. 2, 20-day-old ducks (4 replicate pens, 60 ducks/pen) were randomly allotted to 3 dietary fat sources (soybean oil, lard, and palm oil) with or without emulsifier in a 3 × 2 factorial arrangement. In Exp. 1, increasing ME and CP level improved (P < 0.05) body weight gain (BWG) and cost-to-gain ratio linearly, but reduced (P < 0.05) feed intake (FI) and feed-to-gain ratio (F/G) linearly. Breast skin thickness and liver redness (a*) value increased (P < 0.05) linearly with the increasing ME and CP level. In Exp. 2, no interactions between fat sources and emulsifier were observed. Feeding lard and palm oil diets increased (P < 0.05) final BW and BWG compared to soybean oil. Birds fed soybean oil and palm oil diets had lower (P < 0.05) FI compared to those fed lard diet. F/G in soybean oil and lard groups was higher (P < 0.05) compared to palm oil group. Birds in palm oil and lard groups had higher (P < 0.05) European production efficiency factor than those in soybean oil group. The addition of emulsifier increased (P < 0.05) BWG. In summary, the optimal ME and CP level for roasting was 2,950 kcal/kg ME and 16.5% CP and the palm oil was better than soybean oil and lard in Pekin ducks from 15 to 40 D of age.

Abstract
This study was conducted to determine the effect of methylsulfonylmethane (MSM) on growth performance, immune function, antioxidant capacity, and meat quality in Pekin ducks. A total of 960 female 1-day-old Pekin ducklings (53.3 ± 0.4 g) were randomly allotted to 3 treatments with 8 replicates of 40 birds, based on their body weight (BW). The experiment lasted 6 wks, and dietary treatments included a corn–soybean meal–based diet supplemented with 0%, 0.15%, and 0.3% MSM, that is, CON, MSM1, and MSM2, respectively. Growth performance, serum profiles, and meat quality were determined. During the period of days 22–42, BW gain (BWG) in MSM2 treatment was higher (P < 0.05) and feed-to-gain ratio (F/G) was lower (P < 0.05) than those of CON and MSM1 treatments. BW gain and final BW in MSM2 treatment were increased (P < 0.05) compared with CON and MSM1 treatments during the period of days 1–42. Serum activities of superoxide dismutase and glutathione peroxidase, total antioxidative capacity, and concentrations of interleukin-2 and interleukin-6 were higher (P < 0.05) in MSM2 than in CON treatment. Ducks in the MSM2 treatment group had lower (P < 0.05) serum malondialdehyde, interferon gamma, and tumor necrosis factor-α levels than those in the CON treatment group. The supplementation of MSM increased (P < 0.05) water-holding capacity and redness (a*) and decreased (P < 0.05) values for 2-thiobarbituric acid and drip loss on day 5. Ducks in the MSM2 treatment group had higher (P < 0.05) pH24h than those in the CON treatment group. Taken together, the inclusion of MSM (0.3%) increased final BW and BWG during periods of days 22–42 and days 1–42, reduced feed-to-gain ratio during the period of days 22–42, and resulted in positive effects on immunity, antioxidant capacity, and meat quality.

Abstract
Objective: To explore the value of contrast-enhanced CT combined with texture analysis in differentiating pancreatic cancer from mass-forming pancreatitis in pancreatic head. Methods: A retrospective study collected 21 patients with pancreatic head mass-forming pancreatitis confirmed by surgery or biopsy and 47 patients with pancreatic ductal adenocarcinoma confirmed by surgery. The patients visited the Affiliated Hospital of Nanjing University of Chinese Medicine and the First Affiliated Hospital of Wannan Medical College between January 2014 and December 2017. Gender, age and CT findings were collected. The parenchymal phase was selected for texture analysis. The minimum absolute shrinkage and selection operator (LASSO) method was applied for dimensionality reduction.Two independent sample t-tests or Mann-Whitney U test were used for continuous variables based on the Shapiro-Wilks normality test results. Categorical variables were tested by Chi-square or Fisher test. By multivariable regression analysis, CT findings, CT texture analysis, CT findings combined with texture analysis prediction models were established. The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic performance of individual indicators and each prediction model. The Delong test was used to compare the area under the curve (AUC) of each model. Results: The CT findings prediction model consisted of CT value of lesion on pancreatic parenchymal phase and pancreatic duct penetrating sign. The texture analysis prediction model consists of root mean square and low grey level run emphasis_angle135. The AUC of them were not statistically different (Z=0.150,P>0.05). The combined predictive model had the better diagnostic performance (AUC 0.944, sensitivity 83.0%, specificity 95.2%, +LR 17.43, -LR 0.18) than CT sign prediction model (Z=2.008, P<0.05) and texture analysis prediction model(Z=2.236, P<0.05) were significantly different. Conclusions: The CT findings model and the texture analysis model have equivalent diagnostic performance in the differentiation of mass-forming pancreatitis and pancreatic cancer. The enhanced CT combined with texture analysis model has the best diagnostic efficiency and can further improve the diagnostic ability.

Abstract
OBJECTIVE This study was conducted to determine the effects of stale maize on growth performance, immunity, intestinal morphology, and antioxidant capacity in broilers. METHODS A total of 800 one-day-old male Arbor Acres broilers (45.4±0.5 g) were blocked based on body weight, and then allocated randomly to 2 treatments with 20 cages per treatment and 20 broilers per cage in this 6-week experiment. Dietary treatments included a basal diet and diets with 100% of control maize replaced by stale maize. RESULTS The content of fat acidity value was higher (p<0.05) while the starch, activities of catalase and peroxidase were lower (p<0.05) than the control maize. Feeding stale maize diets reduced (p<0.05) average daily feed intake (ADFI) throughout the experiment, feed conversion ratio (FCR) during d 0 to 21 and the whole experiment as well as relative weight of liver, spleen, bursa of Fabricius and thymus (p<0.05) on d 21. Feeding stale maize diets decreased jejunum villus height (VH) and VH/crypt depth (CD) (p<0.05) on d 21 and 42 as well as ileum VH/CD on d 42. The levels of immunoglobulin G, acid α-naphthylacetate esterase positive ratios and lymphocyte proliferation on d 21 and 42 as well as lysozyme activity and avian influenza antibody H5N1 titer on d 21 decreased (p<0.05) by the stale maize. Feeding stale maize diets reduced (p<0.05) serum interferon-γ, tumor necrosis factor-α, interleukin-2 on d 21 and interleukin-6 on d 21 and 42. Broilers fed stale maize diets had lower levels of (p<0.05) total antioxidative capacity on d 42, superoxide dismutase and glutathione peroxidase on d 21 and 42, but higher (p<0.05) levels of malondialdehyde on d 21 and 42. CONCLUSION Feeding 100% stale maize decreased ADFI and FCR, caused adverse effects on immunity and antioxidant function and altered intestinal morphology in broilers.

Abstract
Objective: To analyze the clinicopathological features and differential diagnosis of interdigitating dendritic cell sarcoma (IDCS). Methods: The clinical pathological features of 7 IDCS were analyzed. Among them, the follow-up results of 6 cases were available. Results: Among the 7 IDCS patients, 4 cases were male and 3 were female. The age of the patients ranged from 26 to 69 years.Three cases were originated from lymph nodes and 4 cases were originated from skin, stomach, adrenal gland and mesentery, respectively. Microscopically, the tumor cells presented as fascicular and storiform proliferation and infiltrated by lymphocytes. The tumor cells were short-spindle or ovoid, with indistinct border of cytoplasm. The immunohistochemistry results showed that tumor cells were S-100, Vim, CD68 and CD163 positive, and AE1/AE3, EMA, CD117, CD34, Desmin, SMA, CD1α, CD21, CD23, CD35, HMB45, Melan-A, MelanPan and ALK negative.The BRAF mutation and clonal rearrangement of T and B cells were not detected. Among the follow-up period of 7 IDCS patients, 3 occurred disease progressions. Conclusions: IDCS is extremely rare with unique pathological features, and its lesion is not limited to the lymph node. The IDCS patients with extensive lesions may have worse prognose. The differential diagnosis of IDCS includes other histiocytic and dendritic cell neoplasms, malignant melanoma and soft tissue neoplasms.

Abstract
Objective The study was conducted to evaluate the effects of the absorbent (a mixture of activated carbon and hydrated sodium calcium aluminosilicate) on growth performance, blood profiles and hepatic genes expression in broilers fed diets naturally contaminated with aflatoxin. Methods A total of 1,200 one-day-old male chicks were randomly assigned to 6 treatments with 10 replicate cages per treatment. The dietary treatments were as follows: i) control (basal diets); ii) 50% contaminated corn; iii) 100% contaminated corn; iv) control+1% adsorbent; v) 50% contaminated corn+1% absorbent; vi) 100% contaminated corn+1% absorbent. Results During d 1 to 21, feeding contaminated diets reduced (p<0.05) body weight (BW), average daily gain (ADG), and average daily feed intake (ADFI), but increased (p<0.05) feed-to-gain ratio (F/G). The absorbent supplementation increased (p<0.05) BW, ADG, and ADFI. There were interactions (p<0.05) in BW, ADG, and ADFI between contaminated corn and absorbent. Overall, birds fed 100% contaminated diets had lower (p<0.05) final BW and ADG, but higher (p<0.05) F/G compared to those fed control diets. The absorbent addition increased (p<0.05) serum albumin concentration on d 14 and 28 and total protein (TP) level on d 28, decreased (p<0.05) alanine transaminase activity on d 14 and activities of aspartate aminotransferase and alkaline phosphatase on d 28. Feeding contaminated diets reduced (p<0.05) hepatic TP content on d 28 and 42. The contaminated diets upregulated (p<0.05) expression of interleukin-6, catalase (CAT), and superoxide dismutase (SOD), but downregulated (p<0.05) glutathione S-transferase (GST) expression in liver. The absorbent supplementation increased (p<0.05) interleukin-1β, CAT, SOD, cytochrome P450 1A1 and GST expression in liver. There were interactions (p<0.05) in the expression of hepatic CAT, SOD, and GST between contaminated corn and absorbent. Conclusion The results suggest that the naturally aflatoxin-contaminated corn depressed growth performance, while the adsorbent could partially attenuate the adverse effects of aflatoxin on growth performance, blood profiles and hepatic genes expression in broilers.

Abstract
Objective:To investigate the diagnostic efficiency of HCY and NO/ET-1 to cognitive dysfunction in patients with severe obstructive sleep apnea hypopnea syndrome, and to interfere with the cognitive function of severe OSAHS patients. Method: Eighty-six patients with OSAHS were divided into mild group (22 cases), moderate group (23 cases), severe group (41 cases) and healthy physical examination group (50 cases). The levels of serum HCY and NO/ET-1 were compared between the four groups. The Montreal cognitive assessment scale was used to evaluate the incidence of mild cognitive impairment in severe OSAHS group, and the correlation between the level of serum HCY, NO/ET-1 and cognitive function in severe OSAHS group was analyzed. Result:The level of serum HCY in patients with severe OSAHS with cognitive impairment was(32.28±3.92)μmol/L, higher than that of the cognitive moderate group(26.34±4.05)μmol/L, and mild group (18.62±3.29)μmol/L. The level of serum NO/ET-1 in patients with severe OSAHS with cognitive impairment was (0.69±0.19), higher than that of the cognitive moderate group(2.76±0.28), and mild group (3.98±0.37), the difference was statistically significant (P<0.05). In severe group, there was a negative correlation between the level of serum HCY and the score of MoCA and its subscores (P<0.05), and there was a positive correlation between the total scores of NO/ET-1 and MoCA and their subscores (P<0.05), and negative correlation between HCY and NO/ET-1 (P<0.05). The area under the ROC curve of predicting serum HCY and NO/ET-1 levels in severe OSAHS patients with cognitive impairment were 0.788(95%CI0.654-0.921) and 0.770 (95%CI0.642-0.899). Conclusion:Serum HCY and NO/ET-1 were the factors influencing the formation of cognitive impairment in severe OSAHS patients. The level of HCY was negatively correlated with the degree of cognitive impairment, and NO/ET-1 was positively correlated with the degree of cognitive impairment.

Abstract
In March 2017, a severely burned male patient aged 36 years with hypovolemic shock was admitted to our hospital. The patient received large quantities of antibiotics and blood products and repeated skin graft after admission, and then he suffered wound errhysis and throat congestion. The patient was healthy before without family history of bleeding or thrombosis disease. Laboratory tests showed that prothrombin time and activated partial coagulation time were remarkably prolonged, blood coagulation factor Ⅴ activity was extremely low, and the result of qualitative test of coagulation factor inhibitor was positive. Acquired blood coagulation factor Ⅴ deficiency was diagnosed. After application of dexamethasone (5 mg, twice per day) and infusion of fresh frozen plasma, blood coagulation indicators of patients recovered in 4 days, the result of qualitative test of coagulation factor inhibitor was negative, and bleeding symptoms were improved.

METHODS A total of 240 weanling pigs ([Yorkshire×Landrace]×Duroc) with an average body weight (BW) of 6.3±0.15 kg were used in this 28-day trial. Pigs were randomly allocated in 1 of the following 4 dietary treatments in a 2×2 factorial arrangement with 2 levels of probiotics (0 and 500 mg/kg probiotics) and XOS (0 and 200 mg/kg XOS) based on the BW and sex. RESULTS Administration of probiotics or XOS improved average daily gain (p<0.05) during 0 to 14 d and the overall period, while pigs that were treated with XOS had a greater average daily gain and feed efficiency (p<0.05) compared with unsupplemented treatments throughout 15 to 28 d and the whole experiment. Either probiotics or XOS treatments increased the apparent total tract digestibility of nutrients (p<0.05) during 0 to 14 d. No effects on serum profiles were observed among treatments. The XOS increased villus height: crypt depth ratio in jejunum (p<0.05). The supplementation of probiotics (500 mg/kg) or XOS (200 mg/kg) alone improved the apparent total tract digestibility of dry matter, nitrogen and gross energy on d 14, the activity of trypsin and decreased fecal NH3 concentration (p<0.05). Administration of XOS decreased fecal Escherichia coli counts (p<0.05), while increased lactobacilli (p<0.05) on d 14. There was no interaction between dietary supplementation of probiotics and XOS. CONCLUSION Inclusion of XOS at 200 mg/kg or probiotics (Bacillus subtilis and Enterococcus faecium) at 500 mg/kg in diets containing no antibiotics significantly improved the growth performance of weanling pigs. Once XOS is supplemented, further providing of probiotics is not needed since it exerts little additional effects.

Abstract
Background: Previous studies have found that schoolchildren with attention-deficit/hyperactivity disorder (ADHD) showed difficulties in neuropsychological function. This study aimed to assess neuropsychological function in Chinese preschoolers with ADHD using broad neuropsychological measures and rating scales and to test whether the pattern and severity of neuropsychological weakness differed among ADHD presentations in preschool children. Methods: The 226 preschoolers (163 with ADHD and 63 controls) with the age of 4–5 years were included and assessed using the Behavior Rating Scale of Executive Function-Preschool Version (BRIEF-P) and a series of tests to investigate neuropsychological function. Results: Preschoolers with ADHD showed higher scores in all domains of the BRIEF-P (inhibition: 30.64 ± 5.78 vs.20.69 ± 3.86, P < 0.001; shift: 13.40 ± 3.03 vs.12.41 ± 2.79, P = 0.039; emotional control:15.10 ± 3.53 vs.12.20 ± 2.46, P < 0.001; working memory: 28.41 ± 4.99 vs.20.95 ± 4.60, P < 0.001; plan/organize: 17.04 ± 3.30 vs.13.29 ± 2.40, P < 0.001) and lower scores of Statue (23.18 ± 7.84 vs.28.27 ± 3.18, P = 0.001), Word Generation (15.22 ± 6.52 vs.19.53 ± 7.69, P = 0.025), Comprehension of Instructions (14.00 ± 4.44 vs.17.02 ± 3.39, P = 0.016), Visuomotor Precision (P < 0.050), Toy delay (P = 0.048), and Matrices tasks (P = 0.011), compared with normal control. In terms of the differences among ADHD subtypes, all ADHD presentations had higher scores in several domains of the BRIEF-P (P < 0.001), and the ADHD-combined symptoms (ADHD-C) group had the poorest ratings on inhibition and the ability to Plan/Organize. For neuropsychological measures, the results suggested that the ADHD-C group had poorer performances than the ADHD-predominantly inattentive symptoms (ADHD-I) group on Statue tasks (F = 7.34, η2 = 0.12, P < 0.001). Furthermore, the ADHD-hyperactive/impulsive symptoms group had significantly poorer performances compared to the ADHD-C group in the Block Construction task (F = 4.89, η2 = 0.067, P = 0.003). However, no significant group differences were found between the ADHD-I group and normal control. Conclusion: Based on the combined evaluation of performance-based neuropsychological tests and the BRIEF-P, preschoolers with ADHD show difficulties of neuropsychological function in many aspects.

Abstract
OBJECTIVES The level of vitamin D is considered to be associated with the development and progression of heart failure (HF). However, it is still unclear whether supplementation of vitamin D could improve ventricular remodelling in patients with HF. This study aimed to systematically evaluate the influence and safety of additional vitamin D supplementation on ventricular remodelling in patients with HF. DESIGN This study is a meta-analysis of randomised controlled trials (RCTs). SETTING The PubMed, EMBASE, CNKI, Cochrane library, Web of Science databases and grey literature were searched for RCTs regarding the effect of vitamin D on ventricular remodelling in patients with HF (from database creation to October 2017). RevMan V.5.3 software was employed for data analysis. PARTICIPANTS Seven RCTs with a total of 465 patients, including 235 cases in the vitamin D group and 230 cases in the control group, were included. PRIMARY AND SECONDARY OUTCOME MEASURES Left ventricular end-diastolic dimension (LVEDD), left ventricular ejection fraction (LVEF) and the incidence of adverse reactions. RESULTS Compared with the control group, a decrease in the LVEDD (mean difference (MD)=-2.31 mm, 95% CI -4.15 to -0.47, p=0.01) and an increase in the LVEF (MD=4.18%, 95% CI 0.36 to 7.99, p=0.03) were observed in the vitamin D group. Subgroup analysis also revealed a reduced LVEDD in adults (>18 years) and adolescents (<18 years) of the vitamin D group relative to that in those of the control group. High-dose vitamin D (>4000 IU/day) was more effective at reducing the LVEDD than low-dose vitamin D (<4000 IU/day). Moreover, vitamin D supplementation was more effective at reducing the LVEDD and increasing the LVEF in patients with reduced ejection fraction than in patients without reduced ejection fraction. CONCLUSION Vitamin D supplementation inhibits ventricular remodelling and improves cardiac function in patients with HF. TRIAL REGISTRATION NUMBER CRD42017073893.

Abstract
Objective: To explore the effects of lappaconitine on intraoperative administration of remifentanil induced postoperative hyperalgesia in general anaesthesia patients. Methods: One hundred and twenty patients from March to October 2016 undergoing elective thyroid operation under general anaesthesia at Ningbo NO.2 hospital, American Society of Anesthesiologists(ASA) Ⅰ or Ⅱ grade, aged 20-60, were enrolled in this study and randomly assigned to 3 groups (n=40). Remifentanil was intraoperatively infused at 0.1 μg·kg(-1)·min(-1) (Group S) or 0.3 μg·kg(-1)·min(-1) (Groups L and G), and patients in group G received lappaconitine 8 mg 30 minutes before the ending of surgery. Mechanical pain thresholds, visual analogue scale (VAS) and additional analgesics were recorded at 2, 6 and 24 hours after the operation. Results: There was no significant difference among the VAS and additional analgesics in three groups at 2, 6 and 24 h after operation (all P>0.05). There was no significant difference among the mechanical pain thresholds in three groups before and 2 h after operation (all P>0.05). The mechanical pain thresholds of group S, L and G was (45.7±15.6), (35.8±15.0), (47.6±16.4)g at 6 h and (50.7±17.0), (33.7±14.0), (49.7±13.9 )g at 24 h after operation. There was significant difference among the mechanical pain thresholds in group S, L and G at 6 h and 24 h after operation (F=6.586, 16.089, all P<0.01). Compared to group S, the mechanical pain thresholds significantly decreased in group L at 6 h and 24 h after operation (q=2.837, 5.045, all P<0.01). While there was a significantly increase in pain thresholds at 6 h and 24 h postoperatively in group G, as compared with the group L (q=3.384, 4.770, all P<0.01). Conclusion: Lappaconitine significantly alleviated intraoperative administration of remifentanil induced postoperative hyperalgesia in general anaesthesia patients.

Abstract
OBJECTIVE To investigate effects of benzo(a)pyrene (BaP) on expressions of insulin-degrading enzyme (IDE) and neprilysin (NEP) which have the ability to degrade β-amyloid (Aβ) in neuroglia cells. METHODS Primary mix-neuroglia cells were cultured from newborn SD rats. After exposure to BaP, Aβ1-42 oligomer or Aβ1-42 fiber individually or jointly for 24 h, the cell survival rate was measured by cell counting kit-8 (CCK-8). Afterwards, the primary mix-neuroglia cells were divided randomly into six groups: Control group, BaP group (2.00 μmol/L), Aβ1-42 oligomer group (20.00 mg/L), BaP plus Aβ1-42 oligomer group, Aβ1-42 fiber group (20.00 mg/L) and BaP plus Aβ1-42 fiber group, of which BaP was pretreated for 12 h followed by cotreatment with different aggregated Aβ1-42. The expressions of IDE and NEP were measured by quantitative real-time polymerase chain reaction (qRT-PCR) for mRNA level and Western blotting for protein level. RESULTS The cell survival rate showed no significant differences after treatment with BaP (≤20.00 μmol/L), Aβ1-42 oligomer (20.00, 40.00 mg/L), Aβ1-42 fiber (20.00, 40.00 mg/L) or cotreatment with BaP and Aβ1-42 oligomer or BaP and Aβ1-42 fiber. Compared with the control group, expressions of IDE and NEP in BaP-treated alone group had no obvious change; however, exposure to Aβ1-42 oligomer alone significantly increased the mRNA and protein level of IDE (P<0.05), and the BaP pretreatment could significantly inhibit the up-regulated expressions of IDE by Aβ1-42 oligomer (P<0.05); on the other hand, exposure either to Aβ1-42 fiber alone or under the BaP pretreatment did not change the mRNA and protein level of IDE and NEP obviously. CONCLUSION On the premise of no significant change of cell survival rate, BaP pretreatment inhibited the up-regulated expressions of IDE in primary mixed neuroglia cells under cotreatment with Aβ oligomer, indicating that BaP may disturb degradation of Aβ oligomer and cause deposition of β-amyloid and further induce cognitive decline and acceleration of Alzheimer.

Abstract
Objective This study was conducted to evaluate the effect of dietary energy and lipase supplementation on growth performance, nutrient digestibility, serum profiles, intestinal morphology, small intestinal digestive enzyme activities, biochemical index of intestinal development and noxious gas emission in weaning pigs. Methods A total of 240 weaning pigs ([Yorkshire×Landrace]×Duroc) with an average body weight (BW) of 7.3±0.12 kg were used in this 28-d experiment. Weaning pigs were randomly allocated to 4 dietary treatments in a 2×2 factorial arrangement with 2 levels of energy (net energy = 2,470 kcal/kg for low energy diet and 2,545 kcal/kg for basal diet) and 2 levels of lipase (0 and 1.5 U/g of lipase) according to BW and sex. There were 6 replications (pens) per treatment and 10 pigs per pen (5 barrows and 5 gilts). Results Weaning pigs fed the low energy diet had lower (p<0.05) gain-to-feed ratio (G:F) throughout the experiment, apparent digestibility of dry matter, nitrogen, ether extract, and gross energy during d 0 to 14, average daily gain during d 15 to 28, lipase activity in duodenum and ileum and protein/DNA in jejunum (p<0.05), respectively. Lipase supplementation had no effect on growth performance but affected apparent nutrient digestibility (p<0.05) on d 14 and enhanced lipase activity in the duodenum and ileum and protease activity in duodenum and jejunum of pigs (p<0.05) fed the low energy diet. Lipase reduced serum low-density lipoprotein cholesterol (LDL-C) and triglyceride (TG), NH3 production (p<0.05) from the feces. Conclusion The low energy diet decreased G:F throughout the experiment and nutrient digestibility during d 0 to 14 as well as lipase activity in duodenum and ileum. Lipase supplementation increased nutrient digestibility during d 0 to 14 and exerted beneficial effects on lipase activity in duodenum and ileum as well as protease activity in duodenum and jejunum, while reduced serum LDL-C, TG and fecal NH3.

Abstract
A study was conducted to evaluate the effect of tail docking on the welfare and performance of victimized pigs by tail biting and tail biters. Pigs ( = 240; 25.7 ± 2.9 kg average weight), including 120 pigs that were tail docked at birth and 120 pigs that remained with intact tails, were used. Pigs were housed in 8 pens of 30 pigs in a confinement barn for 16 wk, with 4 pens each housing pigs of both sexes with docked or intact tails. Tail biters and victimized pigs with damaged tails were identified during outbreaks of tail biting. Growth performance was monitored, and skin lesions on the tail, ears, and body were assessed. Blood samples were collected from focal tail biters, victimized pigs, and nonvictimized pigs for analysis of total serum protein, IgG, and substance P concentrations. When pigs were marketed, carcass weights and the number of pigs with carcass trim loss were recorded. During the growing-finishing period, 48% of pigs with docked tails and 89% of pigs with intact tails experienced lesions on their tails, including 5% of docked pigs and 30% of intact pigs identified as victimized pigs that experienced puncture wounds with signs of infection on their tails or loss of tails ( < 0.001). Victimized pigs tended to gain less weight ( = 0.07) between 17 and 21 wk of age than other pigs when tail biting prevailed in this study. Victimized pigs were more frequently ( = 0.04) sold for less than full value and had a lower dressing percentage ( < 0.001) compared with nonvictimized pigs. For victimized pigs, total serum protein and IgG concentrations were elevated 5 d after tails were injured, suggesting that tail damage can cause inflammation, which may lead to carcass abscesses and trim loss. Compared with victimized pigs and nonvictimized pigs, tail biters had lower total serum protein ( = 0.01) and IgG ( = 0.01) concentrations, indicating that tail biters may experience poor immune functions. Results of this study demonstrated that tail docking reduced tail damage in pigs kept in a confinement system. Tail damage can cause inflammation and reduce the value of market pigs. More research is needed to test whether compromised immune functions predispose pigs to tail biting.

Abstract
The clinical significance of the expression level of serum adrenergic receptor α1 (ADRA1A) in hysterocarcinoma patients was determined. Peripheral serum samples were collected at the Hubei Cancer Hospital from 455 patients affected by hysterocarcinoma and 380 healthy adults, who served as the normal control group. We determined the expression levels of ADRA1A by ELISA and analyzed its correlation to clinical features and prognosis of the patients. Compared with the normal control group, the expression of ADRA1A in the average peripheral serum level of hysterocarcinoma patients was clearly increased (P<0.05). In addition, the expression level of ADRA1A was positively correlated with the FIGO staging for hysterocarcinoma (r=0.312, P=0.014). Furthermore, the expression levels of serum ADRA1A in patients with metastasis were significantly increased compared to the levels of hysterocarcinoma patients without metastasis (P<0.05). Our analyses also showed that the expression levels of serum ADRA1A in hysterocarcinoma patients did not correlate with patient factors such as age, tumor invasive depth, tumor size or tumor differentiation degree (P>0.05). The Kaplan-Meier survival analysis indicated that the median survival time (37.1 months) of patients with a high expression of serum ADRA1A was lower than that of patients with a low expression of serum ADRA1A (68 months) (P<0.05). The three- and five-year survival rates of patients expressing low serum ADRA1A were, respectively, 74.00 and 62.00%; and the three- and five-year survival rates of patients expressing high levels of serum ADRA1A were 52.00 and 32.00%, respectively, with all the differences being statistically significant (P<0.05). ADRA1A was highly expressed in the peripheral serum in patients with hysterocarcinoma and the expression of ADRA1A was associated with FIGO staging and lymph node metastasis status. The expression of serum ADRA1A can be used to assess the survival rate and may be involved in the pathogenesis and metastasis progression of hysterocarcinoma.

Abstract
Genetic-neuroimaging studies could identify new potential endophenotypes of major depressive disorder (MDD). Morphological and functional alterations may be attributable to genetic factors that regulate neurogenesis and neurodegeneration. Given that the association between gene polymorphisms and brain morphology or function has varied across studies, this systematic review aims at evaluating and summarizing all available genetic-neuroimaging studies. Twenty-eight gene variants were evaluated in 64 studies by structural or functional magnetic resonance imaging. Significant genetic-neuroimaging associations were found in monoaminergic genes, BDNF genes, glutamatergic genes, HPA axis genes, and the other common genes, which were consistent with common hypotheses of the pathogenesis of MDD.

Abstract
Atmospheric ammonia in animal housing is reported to have adverse effects on livestock performance and animal health. Previous experiments have found that 75 ppm ammonia reduced the production performance and altered body fat distribution quality of broilers. In this study, we examined the body fat distribution, serum metabolites and lipid metabolism gene expression of broiler exposed to ammonia. A total of 400 chickens were randomly allocated to four groups with four replicates and received ammonia treatments at 0, 25, 50 and 75 ppm, respectively, for 3 weeks. The average daily feed intake and weight gain were decreased when broiler was exposed to ammonia concentration exceeding 50 ppm (p < .05). The increased abdominal fat and reduced thickness of subcutaneous adipose were found in broilers of 75 ppm group (p < .05). When ammonia exceeded 50 ppm, the content of fat in breast muscle of broiler was increased, and when ammonia was higher than 25 ppm, the fat in liver was increased (p < .05). It showed that the fat content in liver was a sensitive index for broilers exposed to ammonia. Furthermore, ammonia exposure had no significant effect on total cholesterol and triglyceride in serum, but significantly increased the relative mRNA expression of acetyl-CoA carboxylase (p = .046) and malic enzyme in liver (p = .038), which indicated that ammonia exposure may increase the de novo fat synthesis in liver. In addition, ammonia increased the high-density lipoprotein cholesterol (p = .02) and activity of hepatic lipase in serum (p < .001), which indicated that ammonia exposure may improve the transportation of cholesterol to liver. To conclude, our results indicated that ammonia exposure might increase the de novo fat synthesis in liver and increased the transportation of cholesterol to liver. In addition, the concentration of ammonia in poultry house should be limited lower than 25 ppm based on the variation of hepatic fat content.

Abstract
AIM To analyse whether the lowest value of lung radiodensity along the passage of the biopsy needle is a quantitative predictor of pneumothorax. MATERIALS AND METHODS CT-guided percutaneous core needle biopsy (PCNB) procedures performed at Zhongnan Hospital were analysed retrospectively. Age, gender, lesion size, lesion depth, lesion location, patient position, number of passages, needle pleural angle, pulmonary bleeding, and lung radiodensity along the needle passage were collected and classified by the extent of pneumothorax. Univariate analysis and multiple logistic regression analysis were assessed to explore the independent risk factors for pneumothorax. RESULTS Six hundred and seventy-seven cases were included in the study, including 456 males and 221 females. Pneumothorax occurred in 40.18% of cases, of which 82.4% were mild, 14% were moderate, and 3.7% were severe. Univariate and multivariate analysis showed that lesion size ≤2 cm (p=0.002), two or more passages (p=0.033), and lung radiodensity of -850 HU or less (p≤0.001) were independent risk factors for pneumothorax; bleeding (p<0.001) was a protective factor for pneumothorax. CONCLUSIONS The lowest value of lung radiodensity along the needle passage was a quantitative predictor of pneumothorax. A value of -850 HU or less was an independent risk factor for pneumothorax. As the value decreased, there was a higher risk of occurrence of more severe pneumothorax.

Abstract
Objective: To study the effects of simulating leg length inequality on the spine and pelvic posture in standing and walking states and to explore their compensatory laws. Methods: From January to April, a total of 44 healthy volunteers were rasterstereographically examined for spine and pelvis in Institute of Digitized Medicine, Wenzhou Medical University and Department of Orthopaedics, First Affiliated Hospital of Wenzhou Medical University.Volunteers wore uniform shoes, and single 5 mm thick insoles were customized.The simulating leg length inequalities (5-30 mm) were artificially created by increasing insole height.The parameters of 3D body surface parameters and 4D dynamic parameters of the pelvic and spine were measured and statistically analyzed in standing and walking states. Results: In the static standing state, with the increase of the difference of both lower extremities, coronal plane pelvic tilt and sagittal plane pelvic torsion also increased[the maximum value about (10.6±4.3) mm and (3.3±3.5)°], as well as the frontal deviation of the spine [the maximum value about (11.1±17.9) mm]. But the pelvic rotation, vertebral surface rotation angle (rms) and spine sagittal plane deviation were no obvious changes.In the walking state, with the difference between lower extremities increased, the maximum angles of vertebral surface rotation to the left and right and pelvic rotation to the left and right were no obvious changes, but (coronal) spinal maximum offset distance to left and right increased [the maximum value about (9.8±5.1), (10.4±6.9) mm]. Conclusion: The effect of the leg length discrepancy on the pelvic coronal plane and the sagittal plane changes are obvious, but little effect has on the pelvic cross section.The pelvis is compensated by the increase of the inclination of the coronal plane and the sagittal angle at first order.Similarly, the effect on the coronal plane of the spine is more markedly, but the changes of sagittal and cross-section of the spine is less affected, the spine is mainly compensated by the coronal plane bending at second order.
