Abstract
BACKGROUND Mild neurocognitive disorder (mNCD) is one of the degenerative diseases that results in memory deficit, and can progress to dementia. The effectiveness of drug therapy for mNCD is still debatable, but treatment of this disease has important implications for postponing or preventing dementia. Jujadokseo-hwan (JDH) is a traditional herbal medicine formulation that exhibits improvement in cognitive abilities and neuroprotective effects. In this study, we will evaluate the safety and efficacy of JDH compared to placebo in mNCD patients. METHODS AND DESIGN This is a randomized, double-blind, placebo-controlled, parallel-group, multicenter clinical trial. After obtaining informed consent from all participants and performing the screening process, the participants will be equally divided into an experimental group and a control group. Each participant will visit the trial center 7 times during the 12 weeks of intervention. The follow up study will be conducted 12 weeks after the intervention ends. The primary outcome is the variance in Seoul verbal learning test-elderly's version (SVLT-E) score from baseline to 12 weeks. Secondary outcomes include scores/values for the following variables: SVLT-E, Rey complex figure test, Digit span test, Korean-Boston naming test, calculation ability, controlled oral word association test, Korean-color word stroop test, digit symbol coding, Korean-trail making test-elderly's version, Korean version of mini mental state examination for dementia screening, euro-qol-5 dimension, pattern identifications tool for cognitive disorders, Korean version of Montreal cognitive assessment, Korean quality of life-Alzheimer disease, computerized tongue image analysis system, blood pressure pulse analyzer, bioelectrical impedance analyzer, wearable electroencephalogram device, functional near-infrared spectroscopy system, and cost analysis. DISCUSSION This is the first trial evaluating the efficacy of JDH for mNCD. We expect this trial will provide strong support for wide use of JDH for mNCD and lead to further research on herbal medicine treatments for mNCD.

Abstract
INTRODUCTION Acute bronchitis is a self-limiting infection of the large airways; cough is the primary symptom, usually lasting for about 3 weeks. Annually, approximately 5% of adults develop acute bronchitis, and its economic burden is substantial. There are also problems of antibiotic abuse in public health systems and symptomatic therapies are commonly prescribed, for which there is insufficient supporting evidence. GHX02 contains four herbs originating from gwaruhaengryeon-hwan, which has been used in the treatment of patients with acute bronchitis in Korea. The objective is to compare the GHX02 and placebo in terms of efficacy and safety, and to determine the appropriate dosage. METHODS AND ANALYSIS We planned a phase II, multicentre, dose-finding, double-blind, randomised placebo-controlled trial of two different doses of GHX02 compared with placebo. A total of 150 patients, aged 19-75 years, with a Bronchitis Severity Score (BSS) ≥5 due to acute bronchitis starting within 2 weeks of study enrolment will be recruited from three university-affiliated hospitals across Korea. Participants will be stratified into three patterns using the Korean Standard Tool of Pattern Identifications of Cough and Sputum and randomly assigned to either a high-dose GHX02 group (1920 mg/day), standard-dose GHX02 group (960 mg/day) or placebo group according to a 1:1:1 allocation ratio. Patients will take medications three times daily for 7 days, with two visiting days. The primary outcome measure is a change in BSS from day 0 to day 7. The secondary outcomes are the Questionnaire of Clinical Symptoms of Cough and Sputum, Leicester Cough Questionnaire, frequency of coughing fits, Integrative Medicine Outcome Scale, Integrative Medicine Patient Satisfaction Scale and withdrawal rate of patients with exacerbation. Safety will be assessed by adverse events, vital signs and laboratory examinations. ETHICS AND DISSEMINATION The study has been approved by our Institutional Review Board (No. DJDSKH-17-DR-14). The trial results will be disseminated via peer-reviewed journals and the Clinical Research Information Service. TRIAL REGISTRATION NUMBER NCT03310385; Pre-results.

Abstract
OBJECTIVE Total arch transposition (TAT) during hybrid endovascular repair for aortic arch disease is believed to allow a better landing zone, but also to be associated with higher peri-operative mortality than partial arch transposition (PAT). Information on this issue is limited. METHOD This study was a retrospective analysis. All 53 consecutive patients with aortic arch disease (41 males, mean age 65.0 years) who underwent hybrid endovascular repair with TAT (zone 0, n=20) or PAT (zone 1 or 2, n=33) from 2008 to 2014 were analyzed retrospectively. The peri-operative and late outcomes of these two groups were compared. RESULTS Baseline characteristics, including EuroSCORE II results, were similar in the two groups. After procedures, peri-operative mortalities and stroke rates were similar in the two groups (5.0% vs. 9.1%, p=1.000, and 10.0% vs. 6.1%, p=.627). Interestingly, all four strokes occurred in patients with a type III aortic arch irrespective of transposition type. Primary success rates (80.0% vs. 69.7%, p=.527) and type I endoleak incidences (20.0% vs. 27.3%, p=.744) were not significantly different. During follow up (mean duration 36.9 months), overall survival (89.7% vs. 87.4% at 1 year and 89.7% vs. 79.3% at 3 years; p=.375) and re-intervention free survival rates (78.6% vs. 92.0% at 1 year; 72.0% vs. 62.2% at 3 years, p=.872) were similar in the two groups. CONCLUSION Morbidity and mortality were high within the first year of hybrid endovascular therapy for aortic arch disease, implying that candidates for hybrid procedures need to be selected carefully. Hybrid endovascular repair with TAT was found to have peri-operative mortality, stroke, and long-term survival rates comparable with PAT, so hybrid endovascular repair may be considered, irrespective of type of arch reconstruction, when clinically indicated.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Gamisoyo-San (GSS) is a well-known Traditional Korean Medicine shown to be effective on mood disorders. AIM OF THE STUDY The purpose of this research is to examine the effect of Gamisoyo-San on generalized anxiety disorder by its differently manufactured preparations. MATERIALS AND METHODS Multicenter, randomized, double-blinded, placebo-controlled study was set for 147 patients with generalized anxiety disorder recruited from November 1st 2009 to December 16th 2010. They were given Gamisoyo-San individual extract mixture (extraction done for each crude materia medica separately) or Gamisoyo-San multi-compound extract (extraction done for whole materia medica at once) or controlled medication. Hamilton Rating Scale for Anxiety (HAM-A), Korean State-Trait Anxiety Inventory (K-STAI), Penn State Worry Questionnaire (PSWQ), Korean Beck Depression Inventroy (K-BDI), Symptom Checklist-90-Revised (SCL-90-R), and Korean WHO Quality of Life Scale Abbreviated Version (WHOQOL-BREF) were evaluated. We also applied Pattern Identification tool for 'JingJi and ZhengChong (, Traditional Korean Medicine term which correlates with generalized anxiety disorder)' to patients to evaluate different responses among 9 patterns. RESULTS HAM-A scores of Gamisoyo-San multi-compound extract group showed greater decrease compared to Gamisoyo-San individual extract mixture group and placebo group, but the difference was insignificant. WHOQOL-BREF scores of Gamisoyo-San multi-compound extract group showed significant increase compared to Gamisoyo-San individual extract mixture group and placebo group. In Heart blood deficiency pattern, the Gamisoyo-San multi-compound extract group showed significant decrease in K-BDI compared to the Gamisoyo-San individual extract mixture group. CONCLUSION Gamisoyo-San did not improve anxiety level of GAD patients. However, it can be useful to improve quality of life, and reduce depressive, obsessive-compulsive, somatic symptoms of generalized anxiety disorder. Gamisoyo-San multi-compound seemed more effective than Gamisoyo-San individual extract mixture, especially in Heart blood deficiency pattern.

Abstract
OBJECTIVE We compared the degree of systemic inflammation and its relation to the angiographic outcomes after drug-eluting stent (DES) implantations. METHODS We implanted a single DES in 79 stable angina patients (50 men; 60.4 (9.5) years of age; sirolimus-eluting stent (SES), n = 38; paclitaxel-eluting stent (PES), n = 41). The high-sensitivity C-reactive protein (hs-CRP) and interleukin 6 (IL-6) levels were determined before and at 24 hours, 72 hours, and 4 weeks after the percutaneous coronary intervention (PCI). An angiography and intravascular ultrasound (IVUS) were performed. RESULTS The hs-CRP and IL-6 levels at baseline did not differ between the two groups. The hs-CRP increased significantly from baseline at 24 hours and 72 hours after the PCI in both groups and there was a significant increase in the IL-6 level at 24 hours after the PCI in both groups. However, there was no significant difference between the two groups in any of the hs-CRP or IL-6 measurements. At follow-up, the late lumen loss was significantly higher in the PES group than in the SES group (0.57 (0.56) mm vs 0.28 (0.58) mm, respectively, p = 0.020). The neointimal hyperplasia (NIH) volume in the PES group was significantly higher than that in the SES group (23.1 (22.7) vs 3.8 (7.1) mm(3), respectively, p = 0.000). The percentage luminal volume reduction was higher in the PES group than in the SES group (18.9 vs 3.9%, p = 0.002). The absolute values or change in the inflammatory markers did not correlate with the NIH or stent volume reduction. CONCLUSIONS Our study showed that the benefits obtained from the SES, which reduce neointimal proliferation, are not probably mediated by the attenuation of the systemic inflammatory markers hs-CRP or IL-6.

Abstract
This study examined whether manual acupuncture at the Siguan points (bilateral points LI4 and LR3) affects intestinal motility in healthy human subjects. Twenty healthy male subjects were randomly assigned either to real acupuncture (RA) at Siguan points or sham acupuncture (SA) groups in a crossover manner. All subjects underwent two experimental sessions; the RA group in the first session was treated with SA in the second session after a 2-week washout period, and vice versa. Each subject took 20 radio-markers and was treated with acupuncture 0, 12, 24, and 36 hours after radio-marker intake. Radiographs were taken at 6, 12.5, 24.5, and 48 hours, and the effect of acupuncture on intestinal motility was evaluated based on the distribution of the radio-markers in the ileum, ascending colon, transverse colon, descending colon, sigmoid/ rectum, and outside the body. Defecating habit was monitored during the trial, and complete blood counts were checked before and after the two acupuncture sessions. The RA and SA results showed extremely similar distributions of the radio-markers in these five regions of the alimentary canal and outside the body in radiographs taken at four different times, verifying that there was no effect of manual acupuncture at the Siguan points on intestinal motility, at least in healthy human subjects.

Abstract
BACKGROUND Using a push-button device, we investigated whether visual or auditory response time would increase with increasing sedation, and assessed the responsiveness score of the Observer's Assessment of Alertness/Sedation (OAA/S) scale at the point of first loss of response to visual or auditory stimulation. METHODS In experiment 1 we applied visual and auditory stimulation to 19 patients as the propofol target plasma concentration (CPT) was increased to determine whether the visual or auditory response would be lost first. Thirty patients were each then infused with propofol, starting at a CPT of 0.3 microg ml(-1) and increasing by increments of 0.2 microg ml(-1), during which visual (experiment 2) or auditory (experiment 3) stimulation was applied when the effect-site concentration (CE) of propofol reached CPT. Visual response time (VRT), auditory response time (ART), CE and total amounts of propofol, and OAA/S score at the first loss of visual/auditory response were measured. RESULTS Visual response disappeared earlier than auditory response in 84.2% of the patients. Visual response time and ART were linearly prolonged as the CE of propofol increased. The CE and total amounts of propofol at the first loss of visual response were 1.2 +/- 0.4 microg ml(-1) and 57.9 +/- 16.7 mg, compared with 1.4 +/- 0.5 microg ml(-1) and 71.6 +/- 26.1 mg, respectively, at the first loss of auditory response. The median (range) OAA/S scores at the first loss of visual and auditory response were 4 (3-4) and 3 (2-4), respectively. CONCLUSION VRT and ART were linearly prolonged with increasing sedation. Visual response may be useful in monitoring conscious sedation.

Abstract
PURPOSE Heptaplatin is a newly developed platinum derivative which has been reported to be less toxic than cisplatin. This study was designed to evaluate the nephrotoxicity of heptaplatin in comparison with that of cisplatin. METHODS Previously untreated advanced gastric cancer patients with normal renal function were randomly assigned into either group I (heptaplatin 400 mg/m(2) i.v. over 1 h on day 1 plus 5-fluorouracil (5-FU) 1000 mg/m(2) per day continuous i.v. from day 1 to day 5), or group II (cisplatin 60 mg/m(2) i.v. over 1 h on day 1 plus 5-FU 1000 mg/m(2) per day continuous i.v. from day 1 to day 5), with the cycles repeated every 4 weeks. Renal function parameters before, during, and after the chemotherapy were compared between the two groups. RESULTS A total of 99 patients were enrolled in the study, 51 in group I and 48 in group II. The 24-h proteinuria on day 5 was markedly increased in group I (95+/-108 mg/day to 9098+/-4514 mg/day, means+/-SD) in comparison with the increase observed in group II (104+/-148 mg/day to 151+/-102 mg/day), and creatinine clearance showed a greater decrease in group I (83.1+/-23.6 ml/min to 44.9+/-17.3 ml/min) than in group II (89.6+/-22.1 ml/min to 72.8+/-21.0 ml/min). The differences in these parameters between the two groups were statistically significant throughout the subsequent cycles. CONCLUSIONS Our findings show that nephrotoxicity was more severe in patients treated with heptaplatin 400 mg/m(2) than with cisplatin 60 mg/m(2) when it was combined with 5-FU. Measures to more effectively prevent nephrotoxicity should be developed for the safe use of heptaplatin.

Abstract
A large left atrial (LA) v. wave can be observed in patients with pure mitral stenosis (MS) because of decreased LA compliance. Few data are available regarding the relation between the magnitude of the LA v wave and pulmonary artery pressure in MS. We hypothesized that pulmonary artery pressure may be higher in patients with decreased LA compliance and thus a large v. wave. We analyzed the right-sided cardiac and transseptal catheterization data in 113 patients (16 men and 97 women, mean age 39 years) with pure rheumatic MS in sinus rhythm. Peak systolic, diastolic, and mean pulmonary artery pressures were measured with right-sided cardiac catheterization. The magnitude of LA a and v. waves were measured through transseptal catheterization. Two-dimensional and Doppler echocardiography were also performed to measure LA size, mitral valve area, mean mitral gradient, and valvular regurgitation. Multiple regression analysis was performed to identify the most important factor in the determination of pulmonary artery pressure. A large v wave, defined if peak v wave height exceeded the mean LA pressure by > or =10 mm Hg, was observed in 43 of 113 patients (38%). Increased pulmonary artery systolic pressure (> or =50 mm Hg) was observed in 38 patients (34%). Univariate analysis showed that the factors associated with increased pulmonary artery systolic pressure were smaller mitral valve area, higher mean mitral gradient, higher mean LA pressure, and higher LA v. wave; among them, LA v wave (p <0. 001) and mean mitral gradient (p<0.001) were significant independent factors for pulmonary artery systolic pressure in multivariate analysis. In conclusion, in patients with pure MS and sinus rhythm, the magnitude of the LA v. wave is strongly associated with pulmonary artery pressure. This finding may suggest that LA compliance is a major contributing factor determining pulmonary artery pressure in pure MS.

Abstract
We examined the relation between the echocardiographic morphology of cardiac myxoma and systemic embolism in 25 patients. Two distinct types of myxoma could be identified by echocardiography: round type characterized by solid and round shape with nonmobile surface (n = 13, 52%), and polypoid type characterized by soft and irregular shape with mobile surface (n = 12, 48%); multiple regression analysis revealed the polypoid type of tumor was the only independent predictor of systemic embolism (p = 0.0029).
