Abstract The study elaborates on the historical development of the home-school-community partnership in the United States, as well as physical activity strategies to prevent overweight and obesity in school age children. Feasible suggestions are proposed for implementing the home-school-community collaboration in China. The finding suggests that in addition to cooperation with schools, families and communities need to take initiatives to actively support children s participation in various physical activities and provide facilities and guarantees. Schools should also do a top level design that links with families and communities, and incorporate their participation into long term physical education planning, making them an integral part of a closely interconnected collaborative network to further prevent overweight and obesity in school age children.

OBJECTIVETo analyze the angiographic features and factors related to the blood supply from right inferior phrenic artery (RIPA) branches in hepatocellular carcinoma (HCC).

METHODSAngiography images of blood supply from RIPA branches and clinical data from patients with HCC who had undergone tmnscatheter arterial chemoembolization in our hospital between 2009 and 2013 were collected for retrospective analysis. Angiographic features of the RIPA branches were assessed for correlation between treatment number, growth pattern, size, tumor location, and rates of blood supplying RIPA branches. Statistical analyses were carried out using chi-square test, t-test, Fisher's exact test and rank sum test.

RESULTSThe 140 patients included in the analysis were grouped according to primary HCC (n=63; group A) and recurrent HCC (n=77; group B) and no statistically significant differences were found between the two groups for incidence of each nutrient branch or total number of nutrient branches. In group A, tumor size was associated with number of nutrient branches (P=0.047). There were 32 cases with HCC lesions in the bare area of the liver, and among those 26 of the cases were supplied by the posterior branch of RIPA. Each branch of RIPA showed greater firequency for particular blood supply areas; the anterior branch (n=55) and lateral branch (n=98) fed tumor lesions in segments 7 and 8, the posterior branch (n=98) fed tumor lesions in segments 6 and 7, and the supra-renal branch (n=10) fed tumor lesions in segment 6. The diaphragmatic branch always fed HCC partly located in segments 4 and 8 (n=17). Unique features were present on the digitally subtracted angiography (DSA) image for each nutrient branch and may be useful for distinguishing in clinical examination.

CONCLUSIONCases of primary HCC and recurrent HCC are not distinguishable by incidence of each nutrient branch or total numbers of the nutrient branches. However, tumor size is related to the number of RIPA nutrient branches, and each RIPA nutrient branch shows a dominant preference for certain blood supply areas, with unique features on DSA.

Small leucine-rich proteoglycans (SLRPs) are necessary structural ingredients of the cornea, which are vital for the establishment and maintenance of corneal transparency.SLRPs are mainly located in the corneal stroma and can be divided into class Ⅰ, class Ⅱ, and class Ⅲ.The compensatory and cooperative interactions among SLRPs regulate the formation and assembly of stromal collagen fibrils, thereby maintaining the highly ordered arrangement of collagen fibrils, and establishing corneal transparency.Decorin and lumican are the main functional components of class Ⅰ and class Ⅱ SLRPs, respectively, and changes in their expression or abnormities in the structure of their core proteins affect the natural content and arrangement of other stromal extracellular matrix components, ultimately resulting in abnormal fibril formation, assembly, and arrangement, causing corneal opacity.SLRPs can regulate corneal wound healing and stromal matrix remodeling via binding to fibrotic molecules and their receptors, which provides bases for corneal diseases therapy and study of molecular mechanisms of corneal transparency.The bioactivities and the role of SLRPs in corneal transparency were reviewed in this article.

Objective: To investigate the relationship between gastrointestinal disorders (GID) and core symptoms or behavioral problems among the children with autism spectrum disorder (ASD) . Method: Totally 328 children with ASD and 202 normal controls were enrolled in this cross-sectional study from August 2013 to October 2016. The information about the gastrointestinal disorders, behavioral and emotional problems was collected by using questionnaires. Childhood Autism Rating Scale (CARS), Autism Behavior Checklist (ABC) were used to assess the core symptoms of the children with ASD. Neurodevelopmental status was evaluated with Gesell Developmental Scale (GDS). These variables were analyzed by using student's t-test and chi-square test. Result: The prevalence of GID was significantly higher in the children with ASD than in the normally developing children (49.4% (162/328) vs.25.7% (52/202), χ²=29.039, P=0.000), especially the symptoms of constipation (33.2% (109/328) vs. 13.9% (28/202)), diarrhea (9.5%(31/328) vs. 1.5% (3/202)), nausea and vomiting (9.5% (31/328) vs. 3.5% (7/202)), and foul defecation (16.5% (54/328) vs. 5.0% (10/202)) (all P<0.05). Among the ASD children, the prevalence of GID was similar between male and female (46.7% (133/285) vs. 46.5%(20/43), χ²=0.006, P=0.938), as well as among all age groups (χ²=1.907, P=0.862). There was no significant difference in scores of GDS in the ASD children with or without GID (all P>0.05). Compared with ASD children without GID (n=166), the ASD children with GID (n=162) got higher scores in the "Body and Object Use" of ABC scale ( (16.4±9.3) vs. (12.3±6.7) scores, t=2.258, P=0.028), and had more emotional problems (63.6% (103/162) vs. 49.4% (82/166), χ²=6.707, P=0.010). Moreover, the score of behavior problems questionnaire was higher in the ASD children with GID ( (35.3±16.8) vs. (16.1±13.6) scores, t=5.748, P=0.000). Conclusion Children with ASD have higher risk of GID than the normal developing children. While the stereotyped behaviors, problem behaviors and emotional problems are severer in the ASD children with GID. Hence, it is important to provide comprehensive treatment and management for these groups of children.
