Organic-inorganic Hybrid ([BrCH2 CH2 N(CH3 )3 ]+ 2 [CdBr4 ]2- ) with Unusual Ferroelectric and Switchable Dielectric Bifunctional Properties over Different Temperature Range.

Both ferroelectric and switchable dielectric behaviors are of great academic value and practical significance, but they usually exist alone. If combine the two properties into one compound, it will be more valuable in practical application. In this paper, quasi-spherical (2-bromoethyl) trimethylammonium cation was used to match with [CdBr4 ]2- anion, and a new organic-inorganic hybrid compound ([BrCH2 CH2 N(CH3 )3 ]+ 2 [CdBr4 ]2- , BETABCdBr) was obtained and carefully characterized. The results indicate that this compound undergoes two continuous reversible phase transition around 342 K and 390 K. It could respectively exhibit ferroelectric and switchable dielectric properties over different temperature range. This work may provide a new clue to explore new types of bifunctional phase transition smart materials to meet various application requirements.

[Ancient clinical application of massage therapy on navel].

To further explore the clinical effect of massage therapy on navel,the related ancient literatures were arranged and analyzed,and several methods in ancient clinical were introduced, including stroking navel, rubbing navel, pushing navel, tapping navel and puffing navel. In addition, the theoretical basis of massage therapy on navel were discussed. The results revealed ancient literatures offered abundant theoretical basis to modern clinical practice, and there were evidences of treating gastroenteric and gynecological diseases with this therapy. Comprehensively, through the study of ancient literatures and modern research, therapy of massage on navel is believed to be promising and will gain popularity in the future.

Rosuvastatin inhibits TGF-beta1 expression and alleviates myocardial fibrosis in diabetic rats.

This study aimed to investigate the effects of rosuvastatin on TGF-beta1 expression, cardiac fibrosis, ventricular remodeling and cardiac function in diabetic cardiomyopathy rats. Twenty-seven diabetic rats induced by streptozotocin intraperitoneal injection were randomly divided into three groups, viz. diabetic, rosuvastatin low-dose (Ros-L) and high dose group (Ros-H). Intervention group were given rosuvastatin 2 mg/kg/d and 5 mg/kg/d orally, respectively. After 10 weeks, the levels of glycosylated hemoglobin (HbA1c), creatine phosphokinase isoenzyme (CK-MB), plasma brain natriuretic peptide (BNP), myocardial collagen volume fraction (CVF) and left ventricular mass index (LVWI) were measured. CK-MB levels in Ros-H and Ros-L rats were lower than in the diabetic group. Rosuvastatin alleviated myofibrosis cordis and fibroplastic proliferation. LVWI, BNP, CVF and TGF-beta1 mRNA and protein levels in the diabetic group were higher than in the control, but were reduced after rosuvastatin treatment. These results demonstrate that rosuvastatin dose-dependently reduces TGF-beta1 expression and inhibits the development of myocardial fibrosis in diabetic cardiomyopathy.
