Objectives : This study is aimed at developing and discussing the prediction model of blood stasis pattern of traditional Korean medicine(TKM) using machine learning algorithms: multiple logistic regression and decision tree model. Methods : First, we reviewed the blood stasis(BS) questionnaires of Korean, Chinese, and Japanese version to make a integrated BS questionnaire of patient-reported outcomes. Through a human subject research, patients-reported BS symptoms data were acquired. Next, experts decisions of 5 Korean medicine doctor were also acquired, and supervised learning models were developed using multiple logistic regression and decision tree. Results : Integrated BS questionnaire with 24 items was developed. Multiple logistic regression models with accuracy of 0.92(male) and 0.95(female) validated by 10-folds cross-validation were constructed. By decision tree modeling methods, male model with 8 decision node and female model with 6 decision node were made. In the both models, symptoms of 'recent physical trauma', 'chest pain', 'numbness', and 'menstrual disorder(female only)' were considered as important factors. Conclusions : Because machine learning, especially supervised learning, can reveal and suggest important or essential factors among the very various symptoms making up a pattern identification, it can be a very useful tool in researching diagnostics of TKM. With a proper patient-reported outcomes or well-structured database, it can also be applied to a pre-screening solutions of healthcare system in Mibyoung stage.

Background: A disputed rpoB mutation is a specific type of rpoB mutation that can cause low-level resistances to rifampin (RIF). Here, we aimed to assess the frequency and types of disputed rpoB mutations in Mycobacterium tuberculosis isolates from South Korea. Methods: Between August 2009 and December 2015, 130 patients exhibited RIF resistance on the MTBDRplus assay at Asan Medical Center. Among these cases, we identified the strains with disputed rpoB mutation by rpoB sequencing analysis, as well as among the M. tuberculosis strains from the International Tuberculosis Research Center (ITRC). Results: Among our cases, disputed rpoB mutations led to RIF resistance in at least 6.9% (9/130) of the strains that also exhibited RIF resistance on the MTBDRplus assay. Moreover, at the ITRC, sequencing of the rpoB gene of 170 strains with the rpoB mutation indicated that 23 strains (13.5%) had the disputed mutations. By combining the findings from the 32 strains from our center and the ITRC, we identified the type of disputed rpoB mutation as follows: CTG511CCG (L511P, n=8), GAC516TAC (D516Y, n=8), CTG533CCG (L533P, n=8), CAC526CTC (H526L, n=4), CAC526AAC (H526N, n=3), and ATG515GTG (M515V, n=1). Conclusion: Disputed rpoB mutations do not seem to be rare among the strains exhibiting RIF resistance in South Korea.

Acupuncture and Radix Astragali aqua-acupuncture stimuli have long been used to cure human diseases. However, it still remains to be unkown on its action mechanism, physiolosical and biochemical aspects. Thus, many attempts were made to show the scientific background covering the above mentioned mechanisms. Most recent studies show that these tests improve blood circulatory system and increase leucocyte counts. In this study, we have applied the acupuncture stimuli to mouse Sinsu(BL-23), which is a stimulative point of oriental medicine, to see if cytokine such as IL-6 can be detected. Mice were treated with lipopolysaccharide(LPS) for inflammation induction, and then reverse transcriptase-polymerase chain reaction (RT-PCR) using each primer set was performed to trace the amounts of mRNA. The results are summarized as follows ; 1. IL-6 was not temporarily expressed in normal mice 15 min after the acupuncture was pulled out. But, it started to show a feeble expression at 30 min after the removal of acupuncture and it started to reduce at 1h. after the acupuncture was pulled out 2. IL-6 was specifically expressed in LPS-treated mouse 30 min after the acupuncture was pulled out. The transcriptional expressions of LPS-treated mice were more effective than those of normal mice at 30 min after the removal of acupuncture 3. IL-6 was not temporarily expressed in normal mice 15 min after Radix Astragali aqua-acupuncture. But it expressed most highly at 30 min, and the transcriptional expressions of IL-6 was continued to 3 h. 4. IL-6 was not expressed in all the time after Radix Astragali aqua-acupuncture in LPS-treated mice. Therefore, a follow-up of cytokine IL-6 can be used not only a basis of the effect of acupuncture and Radix Astragali aqua-acupuncture but a diagnosis giude through the immunological action of thats. And, it is suggested that cytokine's expression by Acupuncture and Radix Astragali aqua-acupuncture stimulation should be continuously elucidated.

In this study, a chemiresistive sensor based on one-dimensional $WO_3$ nanostructures is presented for application in non-invasive medical diagnostics. $WO_3$ nanostructures were used as an active gas sensing layer and were deposited onto a $SiO_2/Si$substrate using Pt interdigitated electrodes (IDEs). The IDE spacing was $5{\mu}m$ and deposition was performed using RF sputter with glancing angle deposition mode. Pt IDEs fabricated by photolithography and dry etching. In comparison with thin film sensor, sensing performance of nanostructure sensor showed an enhanced response of more than 20 times when exposed to 50 ppm acetone at $400^{\circ}C$. Such a remarkable faster response can pave the way for a new generation of exhaled breath analyzers based on chemiresistive sensors which are less expensive, more reliable, and less complicated to be manufactured. Moreover, presented sensor technology has the potential of being used as a personalized medical diagnostics tool in the near future.

Objective : In Donguibogam(東醫寶鑑), like a slow pulse with irregular intervals(結脈), an abrupt pulse(促脈) and a slow and weak pulse with regular intervals(代脈), an uneven pulse is written as a kind of arrhythmia. Such a recognition differs from the present one. In this study, I try to seize the meaning and deliberate whether those expressions are appropriate. Method : 1. Collect and compare the materials of the above four pulses among documentary records of feeling the pulse for diagnosis. 2. Grasp the aspect and trend of changes. 3. Reason whether records in Donguibogam(東醫寶鑑) are proper or not. Result & Conclusions : Donguibogam(東醫寶鑑) written "like a slow pulse with irregular intervals(結脈), an abrupt pulse(促脈) and a slow and weak pulse with regular intervals(代脈), an uneven pulse is written as a kind of arrhythmia". It is not 'an uneven pulse' is written about irregularity of pulse, but 'an uneven pulse' is written about irregularity of the sense able to be felt on the fingertip.

A clinical report indicates that 'Geijibokryunghwan(GBH) is very effective in treating thrombosis in those patients who have difficulties with more conventional antithrombotic drugs. The isolation and identification of various compounds from this plant and the same genus have been reported by several groups. However, the pharmaceutical effect of the GBH on superoxide generation in human neutrophils has not been studied. In the present report, we investigated the possibility of using herbal medicine as an alternative therapy. In particular, we studied tremor in antiatheroscleosis. In this report, we shows the GBH extract can be used as a potential atherosclerosis preventive agent in human. The effect of GBH on stimulus-induced superoxide generation and phosphorylation of tyrosine residues of protein in human neutrophils was investigated. In a conclusion, GBH suppressed tyrosine phosphorylase in a dose-dependent manner, and may have pharmacoceutical applications. These data suggest that GBH extracts merits investigation as a potential anti-atherosclerogenic agent in humans.
