Low pressure, low oxygen concentration, and intense ultraviolet (UV) radiation in high-altitude environments, can cause oxidative stress which can trigger mountain sickness. A recent study demonstrated that hydrogen gas with a good permeability in biological membranes can treat various disorders by exerting its selective anti-oxidation and anti-inflammatory effects, indicating that hydrogen therapy plays a role in scavenging free radicals and in balancing oxidation and anti-oxidation systems of cells. Therefore, we hypothesize that inhaling low-dose hydrogen or drinking hydrogen-saturated water is a novel and simple method to prevent and treat oxidative stress injury caused by low pressure, low oxygen concentration and intense UV radiation in plateaus, thus reducing the risk of mountain sickness.

BACKGROUNDMolecular hydrogen, as a novel antioxidant, has been proven effective in treating many diseases. This study aimed to evaluate the therapeutic effects of hydrogen saturated saline in treatment of a rat model of diabetes mellitus and a rat model of insulin resistant.
METHODSA rat diabetes mellitus model was established by feeding a high fat/high carbohydrate diet followed by injection of a small dose of streptozotocin, and an insulin resistant model was induced with a high glucose and high fat diet. Hydrogen saturated saline was administered to rats with both models conditions on a daily basis for eight weeks. A pioglitazone-treated group and normal saline-treated group served as positive and negative controls. The general condition, body weight, blood glucose, blood lipids, and serum insulin levels of rats were examined at the 8th week after treatment. The oxidative stress indices, including serum superoxide dismutase (SOD), glutathione (GSH) and malondialdehyde (MDA) were also evaluated after eight weeks of treatment using the commercial kits.
RESULTSHydrogen saturated saline showed great efficiency in improving the insulin sensitivity and lowering blood glucose and lipids. Meanwhile, the therapeutic effects of hydrogen saturated saline were superior to those of pioglitazone. Hydrogen saturated saline markedly attenuated the MDA level and elevated the levels of antioxidants SOD and GSH.
CONCLUSIONHydrogen saturated saline may improve the insulin resistance and alleviate the symptoms of diabetes mellitus by reducing the oxidative stress and enhancing the anti-oxidant system.

The present study aims to evaluate the effect of Galla chinensis compounds on the remineralization of two artificial root lesions morphous in vitro. Sixty bovine dentine blocks were divided into two groups and individually treated with two levels of demineralization solutions to form erosive and subsurface artificial carious lesions in vitro. Each group was then divided into three subgroups, each of which were treated with a remineralization solution (positive control), deionized water (negative control), or 4 000 mg⋅L(-1) aqueous solutions of Galla chinensis extract. The dentine blocks were then subjected to a pH-cycling regime for 7 days. During the first 4 days, the daily cycle included 21-h deal and 3-h demineralization applications. The dentine blocks were dealt with the entire day during the remaining 3 days. Two specimens from each of the treatment groups were selected and observed under a polarized light microscope. Data collected using a laser scanning confocal microscope were computerized and analyzed. Galla chinensis extract clearly enhanced the remineralization of both erosive lesion and subsurface lesion patterns in the specimens (P<0.05). The level of remineralization of the erosive lesion by Galla chinensis extract was lower than that of the subsurface lesion (P<0.05). In addition, the remineralization of the subsurface lesion by Galla chinensis extract was higher than that of the remineralization solution (P<0.05). No significant difference between the remineralization of erosive lesions by Galla chinensis extract and the remineralization solution was observed (P>0.05). So Galla chinensis extract has the potential to improve the remineralization of artificial root lesions under dynamic pH-cyclic conditions, indicating its potential use as a natural remineralization medicine.

OBJECTIVEDiagnosing asthma in infancy is largely made on the basis of the symptoms of cough and wheezing. A similar presentation can be seen in neurologically normal infants with excessive gastroesophageal reflux (GER). There are no randomized placebo controlled studies in infants using proton pump inhibitors (PPI) alone or in addition to prokinetic agents. The primary objective was to confirm the presence of excessive GER in a population of infants that also had respiratory symptoms suggestive of asthma. Second, in a randomized placebo-controlled fashion, we determined whether treatment of GER with bethanacol and omeprazole could improve these respiratory symptoms.
METHODSInfants (n=22) with a history of chronic cough and wheeze were enrolled, if they had evidence of GER by history and an abnormal pH probe or gastric emptying scan. Infants were randomly allocated to four treatment groups: placebo/placebo (PP), omeprazole plus bethanacol (OB), omeprazole/placebo (OP), bethanacol/placebo (BP). Evaluations by clinic questionnaire and exam, home diary, and pH probe data were done before, after study-medication and after open label of OB.
RESULTSNineteen children were studied. PP did not affect GER or respiratory symptoms, and did not decrease GER measured by pH probe. In contrast, OB decreased GER as measured by pH probe indices and parental assessment. In association, OB significantly decreased daytime coughing and improved respiratory scores. No adverse effects were reported.
CONCLUSIONSIn infants with a clinical presentation suggestive of chronic GER-related cough, the use of omeprazole and bethanacol appears to be viable therapeutic option.

9.Eosinophilic Esophagitis: Update 2012.
The Korean Journal of Gastroenterology 2012;60(1):3-12
Eosinophilic esophagitis (EoE) with adults, as a new disease emerging during the last decade, is a clinicopathologic disorder of the esophagus characterized by a dense esophageal eosinophilic infiltration and typical esophageal symptoms. As numerous studies about EoE had been reported during last several years, updated consensus of EoE was reported in July 2011. The conceptual definition of EoE is coming. EoE is defined as a chronic, immune/antigen-mediated esophageal disease characterized clinically by symptoms related to esophageal dysfunction and histologically by eosinophil-predominat inflammation. Other important addition is genotyping feature that implicates thymic stromal lymphopoietin genes or filagrrin as EoE susceptibility genes. The majority of patients has the concurrent allergic disease, especially food or aeroallergen sensitization. Main therapeutic options include topical steroids and dietary modification. Recent issues of EoE include a new concept for proton pump inhibitor-responsive esophageal eosinophilia that it should be excluded to diagnose EoE.

OBJECTIVES:
This study aimed to observe the color rebound and rebound rates of non-pulp discolored teeth within 1 year after routine internal bleaching to guide clinical practice and prompt prognosis.
METHODS:
In this work, the efficacy of bleaching was observed in 20 patients. The color of discolored teeth was measured by using a computerized colorimeter before bleaching; immediately after bleaching; and at the 1st, 3rd, 6th, 9th, and 12th months after bleaching. The L*, a*, and b* values of the color of cervical, mesial, and incisal parts of the teeth were obtained, and the color change amounts ΔE*, ΔL*, Δa*, and Δb* were calculated. The overall rebound rate (P*) and the color rebound velocity (V*) were also analyzed over time.
RESULTS:
In 20 patients following treatment, the average ΔE* of tooth color change was 14.99. After bleaching, the neck and middle of the teeth ΔE* and ΔL* decreased in the 1st, 3rd, 6th, 9th, and 12th months, and the differences were statistically significant. Meanwhile, from the 9th month after bleaching, the rebound speed was lower than that in the 1st month, and the difference was statistically significant. The incisal end of the tooth ΔE* and ΔL* decreased in the 6th, 9th, and 12th months after bleaching, and the differences were statistically significant. No significant difference was found in the rebound speed between time points. However, this rate settled after the 9th month, with an average color rebound rate of 30.11% in 20 patients.
CONCLUSIONS
The results indicated that internal bleaching could cause a noticeable color change on pulpless teeth. The color rebound after bleaching was mainly caused by lightness (L*), which gradually decreased with time, and it was slightly related to a* and b*. The color of the teeth after internal bleaching rebounded to a certain extent with time, but the color rebound speed became stable from the 9th month. Clinically, secondary internal bleaching can be considered at this time according to whether the colors of the affected tooth and the adjacent tooth are coordinated and depending on the patient's needs.
