This is the first Eastern center-based retrospective report on early complications and associated perioperative factors of nonsyndromic craniosynostosis (NSC). The authors' purpose is to tailor preoperative counseling, convey objective perioperative data, and determinants for early complications in NSC so as to enhance exchanges with international center. Inclusion criteria required a diagnosis of NSC confirmed by 3-dimentional computed tomography scans and complete medical record. Genetic evidence of syndromic craniosynostosis was excluded. Study population was divided into 4 groups based on the suture involvement, which were compared with respect to demographics, perioperative factors, and the occurrence of complications. Demographic data were analyzed using descriptive statistics. Categorical variables were analyzed using the Fisher exact test. Continuous variables were analyzed using the Kruskal-Wallis test. To better study key determinants for early complications, regression analysis was performed. It revealed a predominance of sagittal (n = 36) throughout the time period studied. Eastern China (n = 33) and Southwest China (n = 13) were the top 2 districts where patients came. The authors also reported an overall rate of early complication of 80% (n = 52). The most common were pyrexia (n = 50). Blood loss was a risk (P = 0.041; OR, 1.102); meanwhile, transfusion of concentrated red blood cells was a higher risk (P = 0.035; OR, 2.033). This study represents the authors' initial 4 years practice in NSC. The authors are endeavoring to enhance exchanges with Western centers.

From Jan. 2013 to Nov. 2018, we carried out the investigation on vegetation studies in the ecological monitoring programs, Shenzhen and totally researched 170 plant communities of mountain areas etc., few areas of street regions and parks etc., for communities' structural characteristics and plant diversity. We comparatively analyzed natural forests, semi-natural forest and artificial forest composition and structural characters and family, genus and species diversity level and the main affected factors. We also researched and analyzed these communities' structural characteristics and pant diversity, comparatively analyzed natural forests, semi-natural forest and artificial forest composition and structural characters and family, genus and species diversity level, the main affected factors; researched and analyzed the relationship between plant community structure characteristics with the absorbing ability to PM 2.5 pollutants. The result showed that the structure and plant diversity of natural forest were obviously better than artificial disturbed forest or artificial forest, the semi-natural forest was the middle level of the forests, In the indices of height, DBH, coverage and crow width etc. of tree layer, natural forests and semi-natural forests were obvious higher than that of artificial disturbed forest or artificial forest; in some forests of artificial disturbed forest or artificial forest, though their richness indices of family and How to cite this paper
