The purpose of this study was to analyze the research trends of randomized controlled trials on herbal medicine treatment for atopic dermatitis in China for the last 5 years. We searched for randomized controlled trials with the intervention of herbal medicine for the treatment of atopic dermatitis in the CNKI (China National Knowledge Infrastructure) from January 2014 to December 2018. For the screening of the paper, we used '特应性皮炎' and '异位性皮炎' which mean atopic dermatitis and search was limited to three areas within Medicine & Public Health: Traditional Chinese Medicine, Traditional Chinese Medicinal Herbs, Combination of Traditional Chinese Medicine with Western Medicine. Among the 136 searched studies, we selected a total of 34 studies and analyzed a year of publication, subject characteristics, study design and intervention, prescribed herbal medicine and herbs, pattern identification, evaluation criteria, and outcomes. Longmu decoction (龍牡湯) and Polia Sclerotium (茯笭) was the most frequently prescribed medicine and herb. The most commonly used pattern identification was Blood deficiency and Wind-dryness (血虛風燥), and among them, the most frequently prescribed herb is Rehmanniae Radix (生地黃). In most studies using the total effectiveness and SCORAD index as an outcome measure, the herbal medicine treatment group showed statistically better results than the control group. As a result of the safety assessment, the herbal medicine treatment group was reported having significantly fewer side effects compared to the control group. Hence, it was confirmed that the intervention including herbal medicine had a significant effect on atopic dermatitis. This study would be able to provide the basis of clinical research on atopic dermatitis and applied to the treatment of atopic dermatitis.

4-Hydroxynonenal (4-HNE)는 세포내 레독스의 균형을 깨뜨려 혈관 기능 손상을 일으킨다. 본 연구자들은 HNE의 축적이 야기하는 혈관 기능 손상기전을 더 잘 이해하기 위하여 혈관 내피 세포의 미토콘드리아 세포사 메커니즘을 규명하였다. HNE를 처리한 세포에서는 미토콘드리아 막전위 소실과 그에 따른 cytochrome C의 방출이 유도되었으며, Bax의 증가 및 Bcl-2의 감소가 관찰되었다. ROS 제거제인 NAC와 peroxynitrite 제거제인 페니실라민은 HNE가 유도하는 ROS 생성을 차단하여 cytochrome C 방출과 세포사를 억제하였다. 세포에 HNE와 zVAD-fmk (caspase 저해제)를 같이 처리하면 HNE가 유도하는 세포사를 억제하지 못하는데 이는 HNE에 의한 세포사가 caspase에 비의존적 단계일 가능성을 시사하였다. 위의 결과들은 HNE가 유도하는 혈관 내피 세포의 세포사 매커니즘은 미토콘드리아 막전위의 탈분극에 의해 촉발되며 이는 혈관계 항상성의 악화와 노화에 의해 수반되는 혈관기능 손상을 유도할 것으로 사료된다.

폐포강 대식세포는 사이토카인, 유해산소 대사물을 포함한 그들이 분비하는 물질들로 인해 급성 폐손상에 있어서 직접, 간접적으로 폐손상의 초기반응에 중요한 역할을 담당하는 것으로 알려져 있다. 본 연구에서는 $interleukin-1\alpha$(IL-1)로 유도된 급성 폐손상에서 폐포강 대식세포의 역할을 알아보고자 하였다. 실험군은 대조군과 IL-1투여 후 1시간, 2시간, 3시간, 4시간 그리고 5시간군으로 나누었으며, 폐포강 대식세포와 XO와의 관계를 분석하기 위해 폐세척액 내 XO의 활성도와 폐포강 대식세포, 단핵구, 그리고 호중구의 수적 변화를 측정하였다. 그리고 각 군의 미세구조 변화를 관찰하였다. 실험 결과, 폐포강 내 단핵구의 수는 IL-1투여 후 1시간군에서 대조군과 비교하여 현저히 증가되었으며 (p<0.001), 폐포강 대식세포의 수는 IL-1 투여 2시간 후에 가장 높았고, 폐세척액 내 XO의 활성도는 IL-1 투여 후 점차적으로 증가되다가 3시간 후에 현저히 증가되었다(p<0.05). 폐포강 내 호중구의 수는 IL-1투여 3시간 후부터 뚜렷이 증가되기 시작하였다. 이러한 결과로 보아 IL-1을 기관지 내로 투여한 후 유도된 급성 폐손상에서 폐포강 대식세포에서 유리된 XO는 호중구의 축적에 의한 손상보다 더 초기단계에서 폐손상을 유도하는 인자인 것으로 추정된다.

Immunological activities of the combined-administration of Ginseng Radix Rubra and Vitis Fructus were examined in C57BL/6 mice. Ginseng Radix Rubra and Vitis Fructus were extracted with distilled water or 40% ethyl alcohol. Ginseng Radix Rubra water extracts (GW), the mixture (1:1) of Ginseng Radix Rubra and Vitis Fructus water extracts [GVW(1:1)], the mixture (1:3) of Ginseng Radix Rubra and Vitis Fructus water extracts [GVW(1:3)], 40% ethyl alcohol extracts of Ginseng Radix Rubra (GE), the mixture (1:1) of Ginseng Radix Rubra and Vitis Fructus 40% ethyl alcohol extracts [GVE(1:1)] and the mixture (1:3) of Ginseng Radix Rubra and Vitis Fructus 40% ethyl alcohol extracts [GVE(1:3)] were administered p.o. once a day for 7 days, respectively. GVW(1:1) and GVW(1:3) decreased the viability of thymocytes increased by GW, but GVE(1:1) and GVE(1:3) increased the viability of thymocytes decreased by GE. GVW(1:1) and GVW(1:3) increased the viability of splenocytes decreased by GW or GE. Also, GVW(1:1) and GVE(1:1) enhanced the population of helper T cell in thymocytes, and GVE(1:1) and GVE(1:3) decreased the population of cytotoxic T cells increased by GE. Furthermore, GVW(1:1), GVW(1:3), GVE(1:1) and GVE(1:3) enhanced the population of $B220^+$ cells decreased by GW or GE, and decreased the population of $Thyl^+$ cells increased by GW or GE, and decreased the population of splenic $CD4^+$ cells increased by GW or GE. In addition, GVW(1:1) and GVW(1:3) decreased the phagocytic activity and the production of nitric oxide in peritoneal macrophages increased by GW, but GVE(1:1) and GVE(1:3) enhanced the phagocytic activity and the production of nitric oxide in peritoneal macrophages decreased by GE. These results suggest that Vitis Fructus has an regulative action on immune response of Ginseng Radix Rubra.

This study was done to examine the prognosis according to onset and duration of treatment in acute ischemic cerebral infarction patients. We analysed NIHSS(National Institutes of Health Stroke Scale) score of acute ischemic cerebral infarction patients who visited department of Internal Korean Medicine, one medical center in Busan from January to December 2009. We divided patients into two groups by the initial time of treatment. Group A is admitted within 7 days, Group B is admitted from 7 to 14 days. We used NIHSS for functional recovery after 3 weeks later from admission day, and analyzed prognostic factor by analysis of covariance. All patients showed statistically significant improvement after 1week, 2weeks, 3weeks from admission, and between 1st week and 2nd week. However, there was no significant difference between 2nd week and 3rd week. NIHSS recovery score after 3weeks were analysed according to the timing of treatment. There was a statistically significant difference between two groups. The percentage of aggravated patients showed no statistically significant difference between the two groups. This study suggests that earlier admission care has an effect on functional recovery of patients with acute ischemic cerebral infarction. Further research on the large scale and long-term follow up is required.

Hair loss affects interpersonal relationships and causes psychological stress. In this study, we investigated the antioxidant activity of Cynanchi Wilfordii Radix (CWR) and its effects on dermal papilla (DP) cells. Antioxidant efficacy was examined by ABTS assay. To confirm the effect on cell activity, MTS assay was performed and cell count was directly measured by hemocytometer. The mRNA expression of genes involved in hair formation and hair loss formation was confirmed by quantitative RT-PCR. CWR has a strong antioxidant activity. Cell viability of DP cells was increased to 118.5% by treatment of 0.5 mg/ml CWR for 24 hours, but the effect on the cell number was insignificant. These results suggest that CWR increases mitochondrial activity without promoting cell proliferation. Treatment of DP cells with 0.5 mg/ml CWR resulted in 48.5% reduction of mRNA expression of type 2 $5{\alpha}$-reductase, a major cause of male hair loss. In addition, mRNA expression of bone morphogenetic pretein (BMP), fibroblast growth factor (FGF)7, and FGF10, which are closely related to hair growth, was also decreased. Reactive oxygen species (ROS) acts as a cause of hair loss. The excellent antioxidant efficacy of CWR is thought to be able to effectively remove ROS. The dihydrotestosterone produced by type 2 $5{\alpha}$-reductase in DP cells is a potent inducer of male pattern hair loss. The inhibitory effect of type 2 $5{\alpha}$-reductase mRNA on DP cells induced by CWR may induce a positive therapeutic effect of male pattern hair loss.

This study was designed to prove the effect of the Daoyin exercise therapy combined with complex korean medicine treatment on pain and function improvement of low back pain patients. A retrospective observational study. 30 low back pain patients, checked numeric rating scale(NRS) over 5, were treated with the Daoyin exercise therapy combined with complex korean medicine treatment. NRS, roland & morris disability questionnaire(RMDQ), range of motion(ROM), isokinetic muscle strength, and euroqol five demension questionnaire(EQ-5D) were checked to evaluate patients. The Daoyin exercise therapy combined with complex korean medicine treatment reduced NRS $5.67{\pm}1.40$ to $3.73{\pm}1.72$, improved RMDQ $10.33{\pm}4.91$ to $8.17{\pm}5.40$, strengthened lumbar muscle's peak torque and improved EQ-5D $0.56{\pm}0.20$ to $0.63{\pm}0.15$ and euroqol visual analogue scale(EQVAS) $46.80{\pm}19.95$ to $57.50{\pm}19.93$ but had no effect on ROM. NRS decreased significantly as the number of trials increased. No one had serious adverse reactions. As described above, the Daoyin exercise therapy combined with complex korean medicine treatment can help reducing low back pain, improving lumbar function, strengthening lumbar muscle power and stamina and improving quality of life of low back pain patients.

Purpose: With regard to the protective effect of vitamin D against colorectal cancer (CRC), we evaluated genetic variants that might influence vitamin D metabolism: vitamin D receptor (VDR), vitamin D binding protein (GC), vitamin D 25-hydroxylase (CYP2R1), and vitamin D 25-hydroxy 1-alpha hydroxylase (CYP27B1). Materials and Methods: A total of 657 subjects, including 303 cases with CRC and 354 controls were enrolled in this case-control study. All 657 were genotyped for the four gene variants using PCR-RFLP methods. Results: In this study, no significant difference was observed for VDR (rs2238136), GC (rs4588), CYP2R1 (rs12794714), and CYP27B1 (rs3782130) gene variants in either genotype or allele frequencies between the cases with CRC and the controls and this lack of difference remained even after adjustment for age, BMI, sex, smoking status, NSAID use, and family history of CRC. Furthermore, no evidence for effect modification of the variants and CRC by BMI, sex, or tumor site was observed. Conclusions: Our findings do not support a role for VDR, GC, and CYP27B1 genes in CRC risk in our Iranian population. Another interesting finding, which to our knowledge has not been reported previously, was the lack of association with the CYP2R1 gene polymorphism. Nonetheless, our findings require confirmation and possible roles of vitamin D metabolism-related genes in carcinogenesis need to be further investigated.
