  • Objectives : The aim of this study is to review clinical trials using Qigong exercise on patients with hypertension and to assess their methodology and results. Methods : Electronic literature searches for clinical trials (randomized trial, non-randomized trial, before-after study) of Qigong exercise were performed in 21 electronic databases (5 international databases and 16 Korean databases). English, Korean or Chinese articles were included. Laboratory or animal studies were excluded. Results : A total of 11 studies met the inclusion criteria. Five randomized controlled trials, Four non-randomized trials and two before-after studies were included. Seven studies used self-developed Qigong exercise. Two studies used Guolin Qigong exercise and two studies used Qigong exercise with an anti-hypertension drug. Of the nine randomized trials or non-randomized trials, four studies used an anti-hypertension drug control and three studies used waiting list controls. Compared to baseline, a change in blood pressure after the Qigong exercise treatment was significant in all studies. However, the results effect of blood pressure between Qigong exercise and controlled trials were not consistent. Conclusions : There are low-quality clinical trials of Qigong exercise for hypertension. To evaluate the effects of Qigong exercise, more rigorous trials are warranted.

  • More than ten years have passed since the sentinel node (SN) concept for gastric cancer surgery was first discussed. Less invasive modified surgical approaches based on the SN concept have already been put into practice for malignant melanoma and breast cancer, however the SN concept is not yet placed in a standard position in gastric cancer surgery even after two multi-institutional prospective clinical trials, the Japan Clinical Oncology Group trial (JCOG0302) and the Japanese Society for Sentinel Node Navigation Surgery (SNNS) trial. What is the problem in the clinical application of the SN concept to gastric cancer surgery? There is no doubt that we need reliable indicator(s) to determine with certainty the absence of metastasis in the lymph nodes in order to avoid unnecessary lymphadenectomy. There are several matters of debate in performing the actual procedure, such as the type of tracer, the site of injection, how to detect and harvest, how to detect metastases of SNs, and learning period. These issues have to be addressed further to establish the most suitable procedure. Novel technologies such as indocyanine green (ICG) fluorescence imaging and one-step nucleic acid amplification (OSNA) may overcome the current difficulties. Once we know what the problems are and how to tackle them, we can pursue the goal.

  • This review was conducted to investigate clinical trial trend, clinical effect, and study methods of forest healing. Literature search was performed using the search engines of eight electronic databases from inception to march 2010 without language limitation. The search terms were "forest healing", "forest experience", "forest therapy", "forest treatment", "clinical trial", and "clinical study". Inclusion criteria were randomized controlled trials (RCTs) among all kinds of study searched about forest healing. Selection literature and data extraction was performed by authors(SH Sun and SG Lee) independently. Total three studies were selected finally. The methodological quality in all study was low because of poor reporting. Study indications were metal health, depression, self-esteem, and stress. The scale of studies was very small, which was the level of pilot study. There were no description for obtaining informed consent and being reviewed by Institutional Review Board (IRB), and could be any problems for statistical method in any studies. It is difficult to accept the fact that each studies had the significant effect for study indications in the results of studies. It is concluded that the evidence that health healing have a significant effect is insufficient. Further systematic and methodological study and well-designed clinical trial will be needed.

  • Clinical trials of drugs on humans is the final and most important stage in evaluating the safety and efficacy of the drugs. Good Clinical Practice(GCP) standards were announced in 1987 to protect testees' rights as well as to ensure validity of the clinical trial results, but its implementation has been delayed until now. The purpose of this study is to evaluate the preparedness of the designated institutions to abide by GCP standards during clinical trials, and thereby to determine GCP implementability at the institutions. Survey on the status of clinical trials was conducted for the designated 83 clinical trial hospitals. Response rate was 95.2%. Donabedian's quality assessment model was applied as the basic framework for the study. And the relative - weights for the evaluation items were determined by expert's evaluation. Among the designated 83 hospitals, 39 conducted clinical trials to obtain drug manufacturing approval from 1990 to 1994. Only 19 institutions are found to be able to meet the requirements of KGCP. Structure variables - manpower, organization, and facility -, which are the basic elements for GCP, are evaluated as unsatisfied in many hospitals. Institutions which established IRB accounted for 41 or 51.9%, but those who have a protocol evaluation guideline, or Adverse Drug Reaction(ADR) reporting system were only 12 and 21 institutions, respectively. Also, the institutions providing educational programs on conducting clinical trials are few - 20. The study results indicates that the level of conducting KGCP is unsatisfactory. However, more institutions are expected to be able to meet the standards soon because GCP standards does not require so much regulation on facilities, but stress importance on research methodology and human right. At present as the institutions for clinical trials are primarily training hospitals with residency programs, such efforts as education will accelerate the implementability of GCP in Korea. Institutions must build the appropriate infrastructure and government must prepare to strongly enforce KGCP before it can successfully take place.

  • Objectives : To explore the experiences of patients with chronic low back pain(CLBP) in a randomized controlled trial(RCT) of acupuncture. Methods : Five qualitative focus group interviews were conducted at three Korean Medicine Hospitals. Two to 4 participants from the same group(real or sham acupuncture) in the RCT of acupuncture for CLBP discussed their experiences and perceptions of the clinical trial and the acupuncture treatment. Transcribed data were read independently by researchers and analyzed to categorize information and identify themes. Results : A total of 14 participants were included. Most of them discovered positive aspects of being a study subject and a patient. They recognized the differences between experimental and real-world clinical settings such as formal procedures of treatment, and different acupuncture device. Participants also expressed the weaker sensation of acupuncture compared to the previous experience. Especially, they were well aware of the 'subjects' role themselves, thus they observed their changes of symptom closely. As subjects were generally satisfied with their treatment and they had a good feeling to acupuncture after the trial, they expressed their willingness to participate in the future clinical trial of acupuncture. Conclusions : Our finding suggests that the Korean patients' experience of participating in an RCT was generally positive. Their tendency to perform the 'subject' role might affect the trial's process or overall results.
