Rare causes of anemia in children: Two cases of idiopathic pulmonary hemosiderosis.
Respir Med Case Rep
February 2022
Idiopathic pulmonary hemosiderosis (IPH) is a rare cause of diffuse alveolar hemorrhage (DAH) with unknown etiology. Hemoptysis, dyspnea, anemia, diffuse infiltration in chest radiography and presence of hemosiderin-loaded macrophages (HLMs) in the sputum, gastric content or bronchoalveolar lavage fluid (BALF) are the major characteristics for diagnosis of IPH. Here we present two pediatric patients with IPH.

Methods: A total of 266 advanced cancer patients with nausea and vomiting were randomly assigned to Metoclopramide group (M group, ＝70), Metoclopramide plus Haloperidol group (MH group, ＝65), moxibustion ＋ M group (＝63), and moxibustion ＋ MH group (＝68). Moxibustion was applied to bilateral Zusanli (ST 36), and Guanyuan (CV 4), Qihai (CV 6) for 20 min every time, twice a day for 2 weeks.
Article Synopsis
- Islet transplantation is a promising treatment for type 1 diabetes but faces challenges like immune rejection and lack of donor cells, leading researchers to explore the potential of human umbilical cord mesenchymal stem cells (huMSCs) as an alternative source for insulin-producing cells.
- In this study, huMSCs were cultured and induced under specific conditions, displaying changes in cell shape and the ability to express insulin and glucagon, with elevated insulin secretion confirmed through various laboratory techniques.
- The findings suggest that huMSCs can differentiate into insulin-producing cells in the lab, indicating their potential for future therapies aimed at replacing damaged β cells in diabetic patients, although further research is necessary.
Effect of epidermal growth factor and dexamethasone on fetal rat lung development.
Chin Med J (Engl)
September 2009
Background: Epidermal growth factor (EGF), a mitogenic polypeptide that binds to cell surface receptors, is an important regulator of cell differentiation and fetal lung surfactant synthesis. We investigated the preventive and therapeutic effects of EGF in respiratory distress syndrome, by administering EGF and dexamethasone (Dex) to mother rat before delivery.
Methods: Six female Sprague-Dawley (SD) rats were assigned to three groups (2 rats each); EGF or Dex was given to pregnant rats (EGF group and Dex group, respectively) from gestational day 16 to day 18 by intraperitoneal injection, while the group with normal saline injection was used as negative controls.
The increase of ozone concentration in urban is one of the most important research topics on environmental science. With the increase of nitrogen oxides and hydrogen-carbon compounds which are exhausted from cars, the ozone concentration in urban is obviously increased on sunlight, and threat of photochemistry smog will be possible. Therefore, it is very important to monitor and study the ozone concentration distribution in urban.
