Objective To verify the efficiency and stability of hydrogen-rich water preparation with hydrogen-rich rods. Methods ①Seven firenew hydrogen-rich rods were separately placed in seven plastic bottles, each filled with distilled water and soaked for 6 h, before the hydrogen concentration of the water was measured.This process was repeated 10 times.②After the hydrogen-rich rods with the strongest and weakest hydrogen product capacity were removed, the remaining 5 hydrogen-rich rods were placed separately into 5 plastic bottles filled with distilled water,put in a water bath pot at 20,40 and 60℃, respectively, and kept for 2, 4, 6, 8 and 10 h, respectively.Then, the hydrogen concentration, oxidation-reduction potential(ORP),and dissolved oxygen concentration(DO) were measured at various time points.③In order to determine the hydrogen emission rate from the hydrogen-rich water, the hydrogen-rich rods were constantly kept in some samples and the others were removed.All the sample bottle caps were kept open during the experimental process, and the hydrogen concentration was measured at such time points as 0, 10 and 30 min, 1, 2, 5, 12, 24, 30, 48 and 72 h, respectively.Results ①The hydrogen-rich rods used in this study could well meet the requirements.②When the environment temperature was kept constant, the hydrogen concentration of the water was increased with the soaking time of the hydrogen-rich rods, and the ORP of the water was reduced.However, the DO of the water was decreased with the rise of the environment temperature.③When the hydrogen-rich water was kept in opened plastic bottles with a 25 mm oral diameter, the hydrogen concentration of the samples with the hydrogen-rich rods reserved was almost about 0.50 ppm until 72 h, and that of the others was reduced to almost 0 ppm.Conclusion Our results demonstrate that the hydrogen-rich rods test is a simple and effective method for preparing hydrogen-rich water, which will be an valuable and useful method for using hydrogen-rich water in health promotion and prevention of chronic diseases.

Left atrial myxoma is one of the rare causes of cerebral infarction.As the left atrial myxoma complicated artery embolization is more common in cerebral vessels,the first clinical manifestation of about 1/3 patients with left atrial myxoma was cerebral infarction.This article reports a 24-year young female without common vascular risk factors,including hypertension,diabetes,and hyperlipidemia.Multiple cerebral infarctions are the first symptom in patients with left atrial myxoma,and they are analyzed in combination with literature.

Alzheimer's disease(AD)and Parkinson's disease(PD)are common neurodegenerative diseases that seriously threaten the health of the elderly, involving various abnormalities in physiology and metabolism including the impairment of mitochondrial function, Ca 2+ homeostasis deregulation, oxidative stress, aggregation of misfolded proteins, autophagy and inflammation.However, mechanisms underlying the pathogenesis of these diseases have not been clearly elucidated, thus impeding advances in their treatment.In recent years, it has been found that mitochondria-associated endoplasmic reticulum membranes(MAM)play an important role in the development of AD and PD and exert their effects by regulating the functions of mitochondria and endoplasmic reticula.This article reviews studies of the past decade related to the effects of MAM on AD and PD, aiming to generate insights for exploring the constituent proteins of MAM and the molecular mechanisms of AD and PD via endoplasmic reticulum-mitochondria Ca 2+ transport and ER stress regulated by MAM.

Retinopathy of prematurity (ROP) is a proliferative vascular retinal disease. Cryotherapy, laser photocoagulation, intravitreal injection of anti-vascular endothelial growth factor, scleral buckling surgery and vitrectomy are the main treatments. Treated with cryotherapy or laser photocoagulation or intravitreal injection of anti-vascular endothelial growth factor, patients with a history of ROP have thicker foveas, and the morphology of the fovea and the development of the retinal vessels in the macular area are affected, resulting in abnormal vision development. However, the specific mechanisms by which different treatments of ROP affecting the development of the macula are not yet clear. It still need further study with large samples to verify and explore, whether changes in the levels of intraocular vascular endothelial growth factor changing the process of normal macular development and how the abnormal development of the macula affects visual function.

Objective To investigate the treatment effect of atorvastatin in patients with soft carotid atherosclerotic plaques using contrast-enhanced ultrasound(CEUS).Methods Sixty patients with acute cerebral infarction and soft carotid atherosclerotic plaques were divided into two groups:high-dose atorvastatin treatment group(40 mg daily)and control group without atorvastatin treatment.The same soft carotid plaque in each patient was examined before and after 3-months'treatment respectively using CEUS.The parameters of CEUS were compared between pretherapy and post-treatment,including arrived time (AT),time to peak(TTP),peak intensity(PI),based intensity(BI)and enhanced intensity(EI,EI=PI-BI).Results EI of carotid plaques in treatment group was decreased significantly than that in control group after three months'treatment(P＜0.05).While the difference of EI in control group has no significance between pre-therapy and post-treatment(P＞0.05). Conclusions The neovascularization in soft carotid plaques was reduced after 3-months'treatment of a high dose atorvastatin.CEUS can be used to evaluate the effect of atorvastatin in treatment of soft carotid plaques.
