The studies on spa's health promotion effects on healthy or slightly unhealthy persons published in past two decades in Japan have been reviewed. Multidimensional findings from these studies have suggested that the spa resort using may have the effects of increasing and retention of skin and body temperature, improving peripheral circulation function, lowering blood pressure, improving gastrointestinal hormones secretion and increasing gastric mucosal blood flow, bettering metabolism, regulating the function of immune system, regulating the balance of autonomous nervous and internal secretion systems, relieving stress and relaxing, improving the quality of life (QOL), relieving the symptoms of those who are slightly unhealthy, promoting physical strength and fitness, promoting the well-being of the aged, reducing medical expenses of individuals or the community, keeping skin in good shape and restraining the skin's aging.
Of the 58 papers reviewed, the studies of hot spring bathing effects on increasing and retention of skin and body temperature, improving peripheral circulation function and lowering blood pressure were the most in numbers (12 papers, 20.7%), and then the studies of relieving the symptoms of those who were slightly unhealthy (10 papers, 17.2%). Case-control studies (26 papers, 44.8%) were the most used study designs, and then the clinical observation (20 papers, 34.5%). No findings from any one study reviewed in this paper showed that the spa resort using had definite evidence of health promotion effects. Probable effects were suggested from 32 studies (55.2%), but findings from the rest ones (26 papers, 44.8%) showed little evidence to support this consideration. Recently randomized controlled trials (RCT) had been used in studying the health effects of spa resort using in Japan and showed significantly better effects in the intervention group. However, the intervention methods used in the studies were comprehensive health education combing the instructions in appropriate ways of hot spring bathing and education on lifestyle and exercise. It was difficult, if not impossible, to separate the effect of hot spring bathing alone from the combination. The outcomes as effects used in the studies were blood profile, physique and other non-specific items. It may be also difficult to design and carry out a near perfect RCT study on the health promotion effects of spa resort using in field in the future. However, based on experience from past studies it is practicable and important to purse better epidemiological methods such as randomizing and crossover design. On the other side, as specific readers can be influenced marvelously by one book, the health conditions of users may be improved greatly and continuously by some spa. While evidence-based health care places emphasis on RCT, it is also extremely important to inspect the health promotion effects of spa using systematically and rapidly from the viewpoint of narrative-based health care.
2.The relationship between methylation of ERCC1 gene in peripheral blood and in gastric cancer tissues
China Oncology 2013;(11):900-903
Background and purpose: At present, gastric cancer is considered to be both genetic and epigenetic disease, and epigenetic alterations play a significant role in the development of gastric cancer. DNA methylation is the most well studied and most in-depth epigenetic modiifcations in human-beings. The silencing of tumor-related genes by DNA methylation is reversible. ERCC1 is a kind of DNA repair gene. The present study was aimed to detect the CpG island methylation status of ERCC1 gene promoter in gastric cancer tissues and corresponding peripheral blood, and to explore the relationship between methylation of ERCC1 gene in peripheral blood and in gastric cancer tissues. Methods:Methylation speciifc PCR was performed to detect the methylation status of ERCC1 gene in the tumor tissues and the paired peripheral blood from 30 gastric cancer patients. Results:The positive rate of methylation of ERCC1 gene promoter CpG island was 76.7%(23/30) in the tumor tissues and 63.3%(19/30) in serum of gastric cancer patients, and the difference had no statistical signiifcance. Conclusion:Our studies suggest that ERCC1 gene promoter CpG island methylation can be detected in a high proportion of the serum consisting with that in tumor tissues of gastric cancer patients, and the detection of methylation status of ERCC1 gene in peripheral blood provides a more simple, fast and reliable way for the medical treatment of gastric cancer and also provides the possible theoretical basis for the CpG island methylation of ERCC1 gene promoter as a target for the treatment of gastric cancer.
3.Methylation of the ERCC1 gene and its protein expression in gastric cancer
Chinese Journal of Clinical Oncology 2013;(23):1423-1426
Objective:This study aims to detect the CpG island methylation status of the ERCC1 gene promoter and the expres-sion of the ERCC1 protein in gastric cancer tissues, as well as to investigate the correlation and significance between ERCC1 gene pro-moter CpG island methylation and protein expression. Methods:Methylation-specific PCR was performed to detect the methylation sta-tus of the ERCC1 gene in tumor tissues and adjacent cancerous tissues from 30 gastric cancer patients. Ten cases of normal gastric tis-sues were used as control. Expression of the ERCC1 protein in gastric cancer tissues, adjacent cancerous tissues, and normal gastric tis-sues was examined by immunohistochemistry S-P method. Results:The methylation rate of the ERCC1 gene promoter CpG island in gastric cancer tissues was significantly higher than that in adjacent cancerous tissues (76.7%vs. 13.3%, P<0.05), and the difference was statistically significant. The incidence of promoter methylation was not found in 10 normal gastric tissues. The negative rate of ERCC1 protein expression in 30 cases of gastric carcinoma tissues was significantly higher than that in adjacent cancerous tissues (70.0% vs. 33.3%, P<0.05), whereas 10 normal gastric tissues all exhibited positive expression for the ERCC1 protein. The tumor tissues with ER-CC1 gene promoter CpG island methylation showed a lower expression of ERCC1 protein than the unmethylated tumor tissues in gas-tric cancer patients. Conclusion:Methylation of the ERCC1 gene promoter CpG island and protein expression are negatively correlat-ed, and methylation of the CpG island of the ERCC1 gene may be one of the main reasons for the down-regulation of protein expres-sion.
