In order to clarify the differences in the effects of vegetation restoration strategies on soil carbon sequestration and aggregate stability under different water-eroded environments, we collected experimental data from 91 papers and evaluated the response of soil organic carbon (SOC) stock and aggregate stability to vegetation restoration based on Meta-analysis. The results showed the following:① compared with cropland or bare land, forestland/grassland restoration was beneficial to increase SOC stock and improve aggregate stability, but the dominant functions of the two were different. The effect of forestland restoration on carbon sequestration was stronger than that of grassland reforestation, and the effect of grassland restoration on aggregate stability was stronger than that of forestland restoration.

The boundary conditions of the cylindrical shells were one end fixed and the other free. The carbon fiber stacking sequences were [±90]/([±20]/[±90]/[±40]/[±90]/[±60]/[±90])/[±90].

This condition primarily occurs in infants and young children, usually with acute onset and rapid progression. This review article introduced standardized recommendations for the pathogenesis, clinical manifestation, diagnostic methods and treatment process of KMP in China, which can be used as a reference for clinical practice.

The aim of this study was to evaluate the efficacy and safety of the combination of prednisone and beta-adrenergic receptor antagonists for refractory IHs.
Methods: We studied 76 patients with refractory IHs.
Cisplatin, a commonly used chemotherapeutic agent for glioma patients, treatment often leads to chemoresistance. Accumulating evidence has demosntrated that microRNA (miRNA/miR) is involved in drug resistance of glioma cells. Nevertheless, the role of miR‑501‑3p in glioma cell resistance to cisplatin is unclear.

Purpose: To summarize the subsequent therapy experiences for infantile hemangiomas after discontinuation of oral propranolol treatment, and explore the relationships between clinical interventions and types of infantile hemangioma.
Methods: In this retrospective study from January 2010 to May 2014, a total of 137 infants with hemangiomas undergoing sequential therapy after oral propranolol treatment. There were 41 males and 96 females.
The critical doping structures of rare-earth atoms in the promising β-SiAlON phosphors have long been argued owing to the lack of direct evidence. Here, the exact locations and coordination of the Ce rare-earth atoms in the β-SiAlON structure have been examined using an atom-resolved Cs-corrected scanning transmission electron microscope. Three different occupation sites for the Ce atoms have been directly observed: two of them are in the structural channel coordinated with six and nine N(O) atoms, respectively; the other one is the unexpected substitution site for Si(Al).

Objective: To summarize the clinical features of vascular malformations complicated with airway obstruction and to evaluate the therapeutic methods of these disease.
Methods: Forty-seven children with airway obstruction and dyspnea (25 males, 22 females) were treated from Jun 1985 to Dec 2007, and their clinical data were retrospectively analyzed. Among 47 patients, there were 27 cases of venous malformations, 17 cases of macrocystic lymphatic malformations, and 3 cases of microcystic lymphatic malformations.
Objective: To evaluate the short-term efficacy and safety of propranolol in the treatment of infantile hemangiomas.
Methods: Between October 2008 and May 2009, oral propranolol was applied to 58 infants with hemangiomas at a dose of 1.0 - 1.
Objective: To summarize the efficacy and safety of employing pneumatic compression therapy in infants with Kasabach-Merritt phenomenon (KMP).
Methods: Seventeen patients with KMP (11 males, 6 females) were treated with pneumatic compression therapy from October 1997 to May 2008. And their clinical characteristics, course of treatment and clinical and laboratory data were retrospectively analyzed.
A total of 204 patients with maxillofacial cavernous haemangiomas were examined by digital subtraction angiography to investigate the factors affecting therapeutic outcome and to optimize treatment selection. Cavernous haemangiomas were classified as high- or low-drainage based on the nature of the draining veins. Patients were randomized to receive either embolization of the draining veins with absolute ethanol followed by bleomycin A5 hydrochloride intra-tumoural injection, or intra-tumoural injection only.
