[Changes of soil microbial phospholipid fatty acid in soil profile under different land use types].

We elucidated the changes of soil microbial biomass and community structure in soil profiles under four typical land use types (farmland, grassland, secondary forest and plantation)and across five soil layers (0-10, 10-20, 20-30, 30-40, 40-50 cm) in the northern mountainous region of Hebei Province. We measured soil microbial biomass by phospholipid fatty acid (PLFA) method, and investigated the effects of land use and soil depth on soil microbial biomass and community structure by variance analysis, correlation analysis and redundancy analysis. The results showed that soil water content, bulk density, and organic carbon content of farmland differed significantly from other land use types.

Analysis of the Risk Factors for Plastic Bronchitis in Children with Severe Adenovirus Pneumonia: A Retrospective Study.

Purpose: Plastic bronchitis (PB), a rare complication of respiratory infection characterized by the formation of casts in the tracheobronchial tree, can lead to airway obstruction and severe condition. Adenovirus is one of the common pathogens of PB caused by infection. This study aimed to evaluate the clinical features and risk factors for PB in children with severe adenovirus pneumonia.

TAK-242 protects against oxygen-glucose deprivation and reoxygenation-induced injury in brain microvascular endothelial cells and alters the expression pattern of lncRNAs.

Background: Deep hypothermic circulatory arrest (DHCA) is a technique used during the surgical treatment of aneurysms of the thoracic aorta in adult patients, and complex congenital heart disease in neonates. And brain microvascular endothelial cells (BMECs) are essential components of the cerebrovascular network and participate in maintaining the blood-brain barrier (BBB) and brain function. In our previous study, we found that oxygen-glucose deprivation and reoxygenation (OGD/R) activated Toll-like receptor 4 (TLR4) signaling in BMECs, and induced pyroptosis and inflammation.

Analysis of mortality risk factors in children with severe adenovirus pneumonia: A single-center retrospective study.

Background: Human adenovirus (HAdV) is one of the most common viruses causing respiratory infections among young children. Most adenovirus infections are mild and self-limited; however, these infections may occasionally cause severe pneumonia and even death. The mortality risk factors for severe adenovirus pneumonia are not completely clear.

MicroRNA-20b suppresses the expression of ZFP-148 in viral myocarditis.

Viral myocarditis is a common cardiovascular disease, which seriously endangers the health of people and even leads to sudden unexpected death. MicroRNAs play very important roles in various physical and pathological processes including cardiogenesis and heart diseases. In recent years, miR-20b has been implicated in various diseases such as breast cancer, gastric cancer, hepatocellular carcinoma, cardiovascular diseases.

[Dominant species population structure and dynamics of natural secondary forest in Mulan-weichang, China].

To explicate the structure and dynamics of dominant tree populations of the natural se-condary forest in Mulanweichang, the canopy stratum composition, diameter class structure, static life table, survival curve, mortality curve, survival function and the time series prediction were studied. The results showed that there were 9 populations in canopy stratum, with Acer mono, Quercus mongolica, Tilia mandshurica and Betula platyphylla as the dominant populations. The survival curve of A.

Glucocorticoid treatment inhibits intracerebral hemorrhage‑induced inflammation by targeting the microRNA‑155/SOCS‑1 signaling pathway.

Intracerebral hemorrhage (ICH) results in inflammation, and glucocorticoids have been proven to be effective inhibitors of ICH‑induced inflammation. However, the precise underlying mechanisms of ICH‑induced inflammation and glucocorticoid function remain largely undefined. Using a mouse ICH model, the present study demonstrated that the short non‑coding RNA molecule microRNA‑155 (miR‑155) is involved in the inflammatory process initiated by ICH in mice.

[Advances in the research on targeted preparations of traditional Chinese medicine and natural drugs].

Targeting dosage form is a kind of targeting drug delivery system which can be used to lock drugs aroud the target organs, tissues, cells and obtain more effective treatment for dose concentration, thus reducing the side-effects of such drugs while increasing their effeciveness. Targeting dosage form is the fourth-generation drug dosage form and it is ideal system for administration because it release the theraping drugs in the targeting-site. Particular emphasis was placed on liposome due to it was used as a drug carrier.

[Maternal and perinatal prognosis affected by the time of termination of pregnancy in patients with hemolysis elevated liver enzymes and low platelet syndrome].

Objective: To investigate the optimal time of termination of pregnancy for patients with hemolysis elevated liver enzymes and low platelet (HELLP) syndrome.

Methods: 57 patients with HELLP syndrome admitted from October 1992 to September 2001 were enrolled. According to the length from the time diagnoses confirmed to the time of delivery, patients were divided into 3 groups; group I, within 24 hours, group II, 24 to 48 hours and group III, over 48 hours.
