Hypoalkaline Phosphatemia Dental Type: A Case Report.

Mutations in dental hypophosphatasia (HPP) have been reported less than those in other types of HPP because the symptoms are mild or the dental lesions are only partial manifestations of other types of HPP. In this case, we observe the clinical manifestation of dental hypoalkaline phosphatase by analyzing the genetic mutation and biochemical parameters in child. The clinical data of the child with odonto HPP were collected and analyzed.

Comparative pharmacokinetics of four major compounds after oral administration of Mori Cortex total flavonoid extract in normal and diabetic rats.

Mori Cortex has been used in traditional Chinese Medicine as an antidiabetic agent. The aim of this study was to establish a UPLC-MS/MS method for simultaneous determination of morin, morusin, umbelliferone and mulberroside A in rat plasma and investigate the pharmacokinetics differences between normal and diabetic rats following oral administration of Mori Cortex total flavonoid extract. Samples were pre-treated by protein precipitation and genkwanin was used as internal standard.

3-Arylcoumarin inhibits vascular calcification by inhibiting the generation of AGEs and anti-oxidative stress.

Objective: This work aims to screen drugs for preventing and treating vascular calcification. We screened a series of 3-arylcoumarins for the detection of vascular calcification-associated factors using human aortic vascular smooth muscle cells.

Results: We found that compounds and significantly inhibited alkaline phosphatase (ALP) activity similar to aminoguanidine hydrochloride (AGH) in a cellular model of AGEs-induced calcification.

SFRP5 mediates downregulation of the wnt5a/caveolin-1/JNK signaling pathway.

This study investigated the effects of Wnt5a/caveolin/JNK signaling pathway and SFRP5 protein on ox-LDL-induced apoptosis of HUVEC cells. The difference of serological indexes between healthy average weight and obese children and the expression of Wnt 5a and SFRP5 was detected by clinical examination, and the correlation between serum SFRP5, Wnt 5a and the vascular endothelial injury was detected. HUVEC cells were induced by ox-LDL to construct an endothelial injury model, siRNA-transfected cells were used to construct downregulated SFRP5 and Wnt 5a expression groups, and recombination methods were used to construct upregulated Wnt5a and SFRP5 expression groups.

Stat5a promotes brown adipocyte differentiation and thermogenic program through binding and transactivating the Kdm6a promoter.

Previous studies reported that Stat5 promotes adipogenesis and white adipocyte differentiation. However, the role of Stat5 in brown adipocyte development is poorly understood. We found Stat5a was higher expressed in brown adipocytes than in white adipocytes, and its level was increased during the process of brown adipocyte differentiation.

Paeonol Derivatives and Pharmacological Activities: A Review of Recent Progress.

Paeonol, 2-hydroxy-4-methoxy acetophenone, is one of the main active ingredients of traditional Chinese medicine such as Cynanchum paniculatum, Paeonia suffruticosa Andr and Paeonia lactiflora Pall. Modern medical research has shown that paeonol has a wide range of pharmacological activities. In recent years, a large number of studies have been carried out on the structure modification of paeonol and the mechanism of action of paeonol derivatives has been studied.

Cucurbitacin E ameliorates lipopolysaccharide-evoked injury, inflammation and MUC5AC expression in bronchial epithelial cells by restraining the HMGB1-TLR4-NF-κB signaling.

Asthma is a chronic inflammatory disorder of airway affecting people from childhood to old age, and is characterized by airway epithelial dysfunction. Cucurbitacin E (CuE), a tetracyclic triterpene isolated from Cucurbitaceae plants, has been recently proved to exert anti-inflammation and immunology regulation activities. Nevertheless, its roles in asthma remains poorly defined.

[The dynamic expression changes of myocardium p-p38MAPK, NF-κB and COX-2 in rats after an exhausted exercise].

Objective: To observe the dynamic expression changes of p38 mitogen-activated protein kinase (p38MAPK), nucler facter kappa B (NF-κB) and cyclooxygenase-2 (COX-2) in myocardial tissue after an exhausted exercise and study the impact of p38MAPK, NF-κB and COX-2 on its myocardial damage.

Methods: Sixty Wister male rats were randomly divided into the control group (n = 10) and the exhausted exercise group (n = 50). Then the exhausted exercise group was further divided into 5 subgroups, namely 0 h, 3 h, 6 h, 12 h, 24 h after an exhausted exercise (n = 10).

SFRP5 correlates with obesity and metabolic syndrome and increases after weight loss in children.

Objective: Secreted frizzled-related protein 5 (SFRP5) is a novel anti-inflammatory adipokine, which has been shown as a mediator between obesity and its comorbidities. The aim of this study was to evaluate the associations of SFRP5 with metabolic syndrome (MetS) and the effects of lifestyle interventions on circulating SFRP5 levels in children.

Design: A cross-sectional study was conducted among 111 obese children and 49 lean controls, and a lifestyle intervention was performed in a subgroup of 31 obese children for 6 months.
