Abstract
Objective: To evaluate the diagnostic value of a histologic scoring system in congenital biliary atresia and its prognostic relevance. Methods: From January 2017 to June 2018 at Children's Hospital of Fudan University, 172 wedge liver biopsy specimens were obtained from infants with neonatal cholestasis [119 patients with congenital biliary atresia (CBA) and 53 patients with non-obstructive cholestasis as control]. A pathologist, single-blinded to the final diagnosis, made the histological diagnosis individually based on an 8-feature (portal ductal proliferation, bile duct reaction, bile plugs in portal ductules, liver fibrosis, edema in portal region, cholestasis, inflammatory cells infiltration in portal region, and ductal plate malformation), 21-point scoring system. Results: The main pathologic changes of biliary atresia were hepatocyte cholestasis, hyperplasia of bile ducts, fibrosis and infiltration of inflammatory cells in the portal area. There were significant difference in the degree of portal edema, bile duct hyperplasia and fibrosis between two groups (P<0.01). In addition, there were characteristic bile duct thrombosis in 97.5%(116/119) of the cases and abnormal development of bile duct plate in 9.2%(11/119) of the cases. Compared with non-CBA infant cholestasis group, the difference was statistically significant (P<0.05). The scoring system has high sensitivity, specificity (both 94.1%) and accuracy (94.3%) in the diagnosis of CBA. A score equal to or more than 11 points supported a diagnosis of CBA; whereas a score less than 11 points might suggest cholestasis. The degree of hepatic fibrosis and ductal plate malformation were related to prognosis. Conclusions: The liver pathology scoring system (8-feature, 21-point) is more accurate in diagnosing CBA than previous methods, which may guide the clinicopathological diagnosis. This histological scoring system also helps to assess the prognosis of CBA.

Abstract
To investigate the effect of exogenous insulin-like growth factor-1 (IGF-1) on the healing of skin ulcers in diabetic rats, male Sprague Dawleys (SD) rats with back skin ulcers were selected and divided into control group, model group and IGF-1 treatment group which received different doses of IGF-1 (0.5, 1.0, 1.5, and 2.0mg/L). The results showed that the healing speed of the skin ulcers was significantly affected by IGF-1, which reduced the size of wound (P less than 0.05). The expression of MMP-9 was enhanced while the expression of TIMP-1 was decreased in diabetic rats with skin ulcers. The IGF-1 treatment helped to re¬store the normal expression of both MMP-9 and TIMP-1 in diabetic rats with skin ulcers, and diabetic skin ulcers in the 1.5 mg/L IGF-1 group showed the best healing. Histological examination showed that after 20 days, fibroblasts in the IGF-1 experimental group with an appropriate concentration increased and the numbers of fibroblasts and capillaries were significantly higher than those of the other groups. Moreover, there were obvious wound surface contractions and re-epithelialization, and the new epithelium moved to the center of the wound faster. Therefore, it is concluded that an appropriate concentration of IGF-1 can significantly promote the healing of skin ulcers in diabetic rats.

Abstract
BACKGROUND AND PURPOSE The International League against Epilepsy (ILAE) updated the classifications of seizures and epilepsies in 2017. The 2017 classifications were compared with the 1980s classifications in rural China. METHODS People with epilepsy receiving treatment under the National Epilepsy Control Programme were recruited from rural areas in China. Their seizures and epileptic syndrome were classified using the 1980s ILAE classification system and then re-classified according to the 2017 system. Differences in seizure, epilepsy and aetiology classifications were identified. RESULTS A total of 597 individuals (58% males, aged 6-78 years) were included. Amongst them 535 (90%) had a single seizure type, 57 (9.55%) had two types and five (0.84%) had three. There was complete agreement between the 1981 and 2017 classifications for the 525 individuals with focal seizures. Seizures originally classified as generalized in 10 of 65 individuals were re-classified as unknown in the 2017 classification. Compared to the 1980s classifications, the proportion of individuals with unknown seizures and unknown epilepsy increased from 1.2% (7/597) to 2.8% (17/597, P = 0.002), and unknown aetiology increased from 32% (189/597: 182 cryptogenic and seven unclassified) to 39% (230/597; P < 0.001) in the 2017 classifications. CONCLUSIONS The 1980s and 2017 classifications had 100% agreement in classifying focal seizures and epilepsy in rural China. A small but significant proportion of generalized seizures and epilepsy and aetiologies classified in the old classifications were re-classified to unknown in the new classifications. These results highlight the need for improvement in clinical evaluation of people with epilepsy in resource-poor settings.

Abstract
Objective:To explore the clinical value of MDCT and post-processing in children with suspected foreign body in trachea.Method:Two hundred patients with suspected tracheal foreign body were treated with 64-slice spiral CT (MDCT) and simulated endoscopic imaging,then compared with seen in bronchoscopy; Compare the results of MDCT and post-processing with the coincidence of intraoperative findings.Result:One hundred and eighty-four cases of positive children were examined by MDCT postprocessing technique and bronchoscopy,179 cases were obstructed by exogenous foreign body,5 cases were phlegm thrombosis (endogenous foreign body) obstruction; 16 cases of children with no foreign body diagnosed by MDCT post-processing technique were also examined by bronchoscopy. The results showed that there was a foreign body in 1 case,and the foreign body was located in the pharyngeal cleft (watermelon spermoderm),and the remaining 15 cases had no foreign body. MDCT and post-treatment techniques for children with tracheal foreign body diagnosis of 99.4% sensitivity,specificity of 75%.There was no significant difference in the detection rate of foreign body between the two techniques of MDCT and post-processing technique and bronchoscopy (P>0.05). Examed by MDCT and postprocessing,we can understand the specific location and size of foreign body,nature,shape preoperatively.Conclusion:Although MDCT and post-processing techniques can not be used to treat tracheal foreign bodies,but the diagnostic rate of bronchial foreign bodies is comparable to that of bronchoscopy. We could apply MDCT examination and post processing before the bronchoscopy,for foreign body inhalation history is not clear,or suspected airway foreign body. We can improve the level of diagnosis and treatment through guiding the operation of bronchoscopy focus.

Abstract
Multiple system atrophy (MSA) is a complex and multifactorial neurodegenerative disease, and its pathogenesis remains uncertain. Patients with MSA or spinocerebellar ataxia (SCA) show overlapping clinical phenotypes. Previous studies have reported that intermediate or long CAG expansions in SCA genes have been associated with other neurodegenerative disease. In this study, we screened for the number of CAG repeats in ATXN1, 2 and 3 in 200 patients with MSA and 314 healthy controls to evaluate possible associations between (CAG)n in these three polyQ-related genes and MSA. Our findings indicated that longer repeat lengths in ATXN2 were associated with increased risk for MSA in Chinese individuals. No relationship was observed between CAG repeat length in the three examined genes and age at onset (AO) of MSA.

Abstract
Microglia are glial-immune cells that are essential for the function and survival of the central nervous system. Microglia not only protect neural tissues from immunological insults, but also play a critical role in neural development and repair. However, little is known about the biology of microglia in the cochlea, the auditory portion of the inner ear. In this study, we detected TMEM119+, CD11b+, CD45+ and Iba1+ populations of cells in the rat cochlea, particularly in Rosenthal's canal, inner sulcus and stria vascularis. Next, we isolated and enriched the population of CD11b+ cells from the cochlea and immortalized these cells with the 12S E1A gene of adenovirus in a replication-incompetent retroviral vector to derive a novel microglial cell line, designated Mocha (microglia of the cochlea). The resulting Mocha cells express a number of markers consistent with microglia and respond to lipopolysaccharide (LPS) stimulation by upregulation of genes (Cox2, ICAM-1, Il6r, Ccl2, Il13Ra and Il15Ra) as well as releasing cytokines (IL-1beta, IL-12, IL-13 and RANTES). As evidence of microglial function, Mocha cells phagocytose fluorescent beads at 37°C, but not at 4°C. The expression pattern of microglial markers in Mocha cells suggests that immortalization leads to a more primitive phenotype, a common phenomenon in immortalized cell lines. In summary, Mocha cells display key characteristics of microglia and are now available as a useful model system for the study of cochlear microglial behavior, both in vitro and in vivo.

Abstract
It remains unresolved how insect embryos acquire sufficient oxygen to sustain high rates of respiratory metabolism during embryogenesis in the absence of a fully developed tracheal system. Our previous work showed that the two distinct subunits (Hc1 and Hc2) of haemocyanin (Hc), a copper-containing protein, display embryo-specific high expression that is essential for embryonic development and survival in the migratory locust Locusta migratoria. Here we investigated the role of haemocyanins in oxygen sensing and supply in the embryo of this locust. Putative binding sites for hypoxia-regulated transcription factors were identified in the promoter region of all of the Hc1 and Hc2 genes. Embryonic expression of haemocyanins was highly upregulated by ambient O2 deprivation, up to 10-fold at 13% O2 content. The degree of upregulation of haemocyanins increased with increasing levels of hypoxia. Compared with low-altitude locusts, embryonic expression of haemocyanins in high-altitude locusts from Tibetan plateau was constitutively higher and more robust to oxygen deprivation. These findings strongly suggest an active involvement of haemocyanins in oxygen exchange in embryos. We thus propose a mechanistic model for embryo respiration in which haemocyanin plays a key role by complementing the tracheal system for oxygen transport during embryogenesis.

Abstract
AIMS To characterize the hemicellulolytic and cellulolytic enzymes from novel fungi, and evaluate the potential of novel enzyme system in releasing ferulic acid (FA) from biomass resource. METHODS AND RESULTS A hemicellulolytic and cellulolytic enzyme-producing fungus 4-14 was isolated from soil by Congo red staining method, and identified as Eupenicillium parvum based on the morphologic and molecular phylogenetic analysis. The optimum temperature of fungal growth was 37°C. Hemicellulolytic and cellulolytic enzymes were produced by this fungus in solid-state fermentation (SSF), and their maximum activities were 554, 385, 218, 2·62 and 5·25 U g(-1) for CMCase, xylanase, β-glucosidase, FPase and FAE respectively. These enzymes displayed the best catalytic ability at low pH values (pH 4·5-5·0). The optimum temperatures were 70°C, 70°C, 75°C and 55°C for CMCase, β-glucosidase, xylanase and FAE respectively. CMCase, xylanase and FAE were stable at different pHs or high temperature (60°C). Enzymatic hydrolysis experiment indicated that the maximum (76·8 ± 4)% of total alkali-extractable FA was released from de-starched wheat bran by the fungal enzyme system. CONCLUSIONS High activities of thermotolerant CMCase, β-glucosidase, xylanase and FAE were produced by the newly isolated fungus E. parvum 4-14 in SSF. The fungal enzyme system displayed high efficiency at releasing FA from wheat bran. SIGNIFICANCE AND IMPACT OF THE STUDY This study provides a new fungal strain for researches of novel hemicellulolytic and cellulolytic enzymes and will improve the bioconversion and utilization of agricultural by-products.

Abstract
UNLABELLED This cross-sectional study investigated the association between the modified 2006 American Heart Association Diet and Lifestyle Recommendations (AHA-DLR) and bone mineral density in Chinese adults. We found that better adherence to the AHA-DLR associated with higher bone mineral density (BMD) at multiple sites. INTRODUCTION Accumulating evidence shows that cardiovascular disease (CVD) and osteoporosis are associated with each other, yet little research has focused on whether strategies to reduce CVD risk could also benefit bone health. We aimed to assess the association between adherence to the modified 2006 American Heart Association Diet and Lifestyle Recommendations (AHA-DLR) and BMD in Chinese adults. METHODS We included 2092 women and 1051 men aged 40-75 years in this community-based cross-sectional study. Dietary information was assessed using a 79-item food frequency survey through face-to-face interviews at baseline (2008-2010) and 3 years later (2011-2013). Adherence to the AHA-DLR was assessed using modified diet and lifestyle scores (American Heart Association Diet and Lifestyle Score (AHA-DLS)) adjusted for bone health. BMD for the whole body, lumbar spine, total hip, femur neck, and trochanter sites was measured using dual-energy X-ray absorptiometry in 2011-2013. RESULTS After adjusting for potential covariates, greater adherence to the modified AHA-DLS was positively and dose-dependently associated with BMD. The mean BMD was 1.93-3.11% higher in quartile 4 (vs. 1) (all p values <0.01) at multiple sites. Five-unit increases in the modified AHA-DLS score were associated with 4.20-6.07, 4.44-8.51, and 3.36-4.67 mg/cm2 increases in BMD at multiple sites for the total subjects, males, and females, respectively (all p values <0.01). CONCLUSIONS Better adherence to the AHA-DLR shows protective associations with BMD at multiple sites in the middle-aged and elderly Chinese population.

Abstract
Recently, we proposed an active thermal extraction (ATX) scheme that enables thermally populated surface phonon polaritons to escape into the far-field. The concept is based on a fluorescence upconversion process that also occurs in laser cooling of solids (LCS). Here, we present a generalized analysis of our scheme using the theoretical framework for LCS. We show that both LCS and ATX can be described with the same mathematical formalism by replacing the electron-phonon coupling parameter in LCS with the electron-photon coupling parameter in ATX. Using this framework, we compare the ideal efficiency and power extracted for the two schemes and examine the parasitic loss mechanisms. This work advances the application of ATX to manipulate near-field thermal radiation for applications such as temperature sensing and active radiative cooling.
