Objective： To obtain fundamental information for the standardization of herbal medicine in Korea. Methods： We analyzed the herbal medicine prescription data of patients at the Pusan National University Korean Medicine Hospital from March 2010 to February 2013. We used the Dongui-Bogam （Dong Yi Bao Jian） to classify prescribed herbal medicines. Results： The study revealed that the most frequently prescribed herbal medicine was ‘Liuwei Dihuang Pill （LWDHP, 六味地黄丸）＇ which was used for invigorating ‘Shen （Kidndy）-yin＇. ‘LWDHP＇ was most frequently prescribed to male patients aged 50-59, 60-69, 70-79 and 80-89 years, and ‘Xionggui Tiaoxue Decoction （XGTXD, 芎归调血饮）＇ was most frequently prescribed to female patients aged 30-39 and 40-49 years. According to the International Classification of Diseases （ICD） codes,‘Diseases of the musculoskeletal system and connective tissue＇ showed the highest prevalence. ‘LWDHP＇ and ＇XGTXD＇ was the most frequently prescribed in categories 5 and 3, respectively. Based on the percentage of prescriptions for each sex, ‘Ziyin Jianghuo Decoction （滋阴降火汤）＇ was prescribed to mainly male patients, and ‘XGTXD＇ with ‘Guima Geban Decoction （桂麻各半汤）＇ were prescribed to mainly female patients. Conclusion： This study analysis successfully determined the frequency of a variety of herbal medicines, and many restorative herbal medicines were identified and frequently administered.

Insights into the pathogenesis of cystoid macular edema: leukostasis and related cytokines

引用

International Journal of Ophthalmology(English edition) 2019年第7期12卷 1202-1208页

作者： Yoo-Ri Chung Young Ho Kim Seung yeop lee Hye-Eun Byeon Kihwang lee Department of Ophthalmology Ajou University School of Medicine Suwon 16499 Korea Institute of Medical Science Ajou University School of Medicine Suwon 16499 Korea

Cystoid macular edema(CME) is the abnormal collection of intraretinal fluid in the macular region, especially in the inner nuclear and outer plexiform layers. CME leads to severe visual impairment in patients with various retinal diseases, such as diabetic retinopathy, retinal vascular occlusion, choroidal neovascularization, and uveitis. Although various retinal conditions lead to CME, a shared pathogenesis of CME is involved in these diseases. Accordingly, the pathogenesis of CME based on vasogenic mechanisms is first discussed in this review, including vascular hyperpermeability, leukostasis, and inflammation. We then describe cytotoxic mechanisms based on retinal Müller cell dysfunction. This comprehensive review will provide an understanding of the pathogenesis of CME for potential therapeutic strategies.

Experimental investigation of friction coefficient in tube hydroforming

引用

Transactions of Nonferrous Metals Society of China 2011年第A1期21卷 194-198页

作者： Hyae Kyung YI Hong Sup YIM Gun yeop lee Sung Mun lee Gi Suk CHUNG Young-Hoon MOON Engineering Research Center for Net Shape and Die Manufacturing School of Mechanical Engineering Pusan National University Technical Research laboratories POSCO Jeonnam 545-090 Korea

The friction coefficient between tube and die in guide zone of tube hydroforming was obtained. In hydroforming, the tube is expanded by an internal pressure against the tool wall. By pushing the tube through tool, a friction force at the contact surface between the tube and the tool occurs. In guiding zone, the friction coefficients between tube and die can be estimated from the measured axial feeding forces. In expansion zone, the friction coefficients between tube and die can be evaluated from the measured geometries of expanded tubes and FE analysis.

Prognostic significance of the neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio in patients with stage Ⅲ and Ⅳcolorectal cancer

AIM To evaluate the prognostic value of the neutrophil-tolymphocyte ratio(NLR) and platelet-to-lymphocyte ratio(PLR) in patients with colorectal cancer(CRC).METHODS Between April 1996 and December 2010, medical records from a total of 1868 patients with CRC were retrospectively reviewed. The values of simple inflammatory markers including NLR and PLR in predicting the long-term outcomes of these patients were evaluated using Kaplan-Meier curves and Cox regression *** The median follow-up duration was 46 mo(interquartile range, 22-73). The estimation of NLR and PLR was based on the time of diagnosis. In multivariate Cox regression analysis, high NLR (≥ 3.0) and high PLR(≥ 160) were independent risk factors predicting poor long-term outcomes in patients with stage Ⅲ and Ⅳ CRC. However, high NLR and high PLR were not prognostic factors in patients with stage Ⅰ and Ⅱ *** In this study, we identified that high NLR (≥ 3.0) and high PLR (≥ 160) are useful prognostic factors to predict long-term outcomes in patients with stage Ⅲ and Ⅳ CRC.

引用

International Journal of Ophthalmology(English edition) 2019年第10期12卷 1555-1560页

作者： Dong-Hyun Kang Yong-Woo lee Kyu-Yeon Hwang Kyung-Min Koh Young-A Kwon Byung-yeop Kim Sang-Wroul Song Kook-Young Kim Myung-Gok Eye Research Institute Department of Ophthalmology Kim’s Eye Hospital Konyang University College of Medicine

AIM: To evaluate the quantitatively changes in lipid layer thickness(LLT) when 3% diquafosol eye drop is used for dry eye patients using the tear film interferometer. METHODS: A total 124 participants(32 males, 92 females;mean age, 28.9 y) diagnosed with dry eye disease(DED) received topical instillation of 4 ophthalmic solutions in one eye: diquafosol, normal saline, 0.1% sodium hyaluronate and 0.3% gatifloxacin, in a masked manner. LLT was measured using an interferometer at baseline and 20 min after the instillation of each ophthalmic ***: Changes of LLT after instillation(nm, mean± standard error) were as follows: 12.6±2.0 for diquafosol(P<0.001), 1.2±2.2 for normal saline(P=0.301), 1.5±2.0 for hyaluronate(P=0.495), and 0.5±3.2 for gatifloxacin(P=0.884).CONCLUSION: Topical instillation of diquafosol increases tear film LLT in DED patients. Diquafosol 3% eye drop might be effective treatment option of evaporative DED with meibomian gland dysfunction.
