Guang Wen Yu,Young Lae Moon,Chae Won Lim 조선대학교 의학연구원 2018 Medical Bilogical Science and Engineering Vol.1 No.1

Three-dimensional measurement and the relative parameters of the glenoid and humeral head in a normal cadaver were evaluated using Mimics and Imageware software to guide the treatment of shoulder instability. The Chinese Digital Man No. 1 and Woman No. 1 were used as the normal cadavers, which were collected and made by the Southern Medical University in Guangzhou, China. Four shoulders were collected from Digital Imaging and Communications in Medicine format by computed tomography scans and three-dimensional reconstructions were performed in Mimics software. The parameters of the glenoid and humeral head were the anteroposterior diameter, supra-inferior diameter, depth and curvature radius of the glenoid labrum, and radius of the humeral head. In Man No. 1, both shoulder showed an anteroposterior diameter of 24.66 and 23.70 mm, respectively; a suprainferior diameter of 34.70 and 33.43 mm, respectively; glenoid labrum depth of 4.05 and 4.01 mm, respectively; curvature radius of the glenoid labrum of 82.43 and 86.35 mm, respectively; and radius of humeral head of 22.16 and 22.22 mm, respectively. In Woman No. 1, both shoulder showed an anteroposterior diameter of 20.40 and 19.96 mm, respectively; a supra-inferior diameter of 29.68 and 29.35 mm, respectively; glenoid labrum depth of 2.48 and 2.34 mm, respectively; curvature radius of the glenoid labrum of 115.84 and 109.59 mm, respectively; and radius of humeral head of 20.48 and 19.80 mm, respectively. The threedimensional measurement of the shoulder parameters is an accurate method by computer software, in which the parameters will provide guidance in choosing the surgical procedure of a shoulder instability.

Microbial Ecology and Diversity : Impact of Diet in Shaping Gut Microbiota Revealed by a Comparative Study in Infants During the First Six Months of Life

( Wen Guang Fan ),( Gui Cheng Huo ),( Xiao Min Li ),( Li Jie Yang ),( Cui Cui Duan ) 한국미생물 · 생명공학회 2014 Journal of microbiology and biotechnology Vol.24 No.2

The development of the gut is controlled and modulated by different interacting mechanisms, such as genetic endowment, intrinsic biological regulatory functions, environment influences and last but no least, the diet influence. In this work, we compared the fecal microbiota of breast-fed (BF), formula-fed (FF), and mixed-fed (MF) infants from Hebei Province, China. By using high-throughput 16S rDNA sequencing analyses, we found some differences in gut microbiota in the three groups. Firmicutes and Proteobacteria were the dominant bacteria at the phylum level in the three groups, where FF infants showed a significant depletion in Bacteroidetes (p < 0.001) and Actinobacteria (p < 0.05). Enterobacteriaceae was the dominant bacteria at the family level in the three groups, but FF infants showed higher Enterobacteriaceae enrichment than BF and MF infants (p < 0.05); the abundance of the Bifidobacteriaceae was only 8.16% in the feces of BF infants, but higher than in MF and FF infants (p < 0.05). The number of genera detected (abundance >0.01%) in BF, MF, and FF infants was only 15, 16, and 13, respectively. This study could provide more accurate and scientific data for the future study of infant intestinal flora.

Wen-Guang Yu 한국전산응용수학회 2009 Journal of applied mathematics & informatics Vol.27 No.5

In this paper, we consider a m-type risk model with Markovmodulated premium rate. A integral equation for the conditional ruin probability is obtained. A recursive inequality for the ruin probability with the stationary initial distribution and the upper bound for the ruin probability with no initial reserve are given. A system of Laplace transforms of non-ruin probabilities, given the initial environment state, is established from a system of integro-differential equations. In the two-state model, explicit formulas for non-ruin probabilities are obtained when the initial reserve is zero or when both claim size distributions belong to the Kn-family, n ∈ N+. One example is given with claim sizes that have exponential distributions. In this paper, we consider a m-type risk model with Markovmodulated premium rate.

Systematic Review and Meta-Analysis of Antibiotic-Impregnated Shunt Catheters on Anti-Infective Effect of Hydrocephalus Shunt

Zhou, Wen-xiu,Hou, Wen-bo,Zhou, Chao,Yin, Yu-xia,Lu, Shou-tao,Liu, Guang,Fang, Yi,Li, Jian-wen,Wang, Yan,Liu, Ai-hua,Zhang, Hai-jun The Korean Neurosurgical Society 2021 Journal of Korean neurosurgical society Vol.64 No.2

Objective : Shunt infection is a common complication while treating hydrocephalus. The antibiotic-impregnated shunt catheter (AISC) was designed to reduce shunt infection rate. A meta-analysis was conducted to study the effectiveness of AISCs in reduction of shunt infection in terms of age, follow-up time and high-risk patient population. Methods : This study reviewed literature from three databases including PubMed, EMBASE, and Cochrane Library (from 2000 to March 2019). Clinical studies from controlled trials for shunt operation were included in this analysis. A subgroup analysis was performed based on the patient's age, follow-up time and high-risk population. The fixed effect in RevMan 5.3 software (Cochrane Collaboration) was used for this meta-analysis. Results : This study included 19 controlled clinical trials including 10105 operations. The analysis demonstrated that AISC could reduce the infection rate in shunt surgery compared to standard shunt catheter (non-AISC) from 8.13% to 4.09% (odds ratio [OR], 0.48; 95% confidence interval [CI], 0.40-0.58; p=0.01; I2=46%). Subgroup analysis of different age groups showed that AISC had significant antimicrobial effects in all three groups (adult, infant, and adolescent). Follow-up time analysis showed that AISC was effective in preventing early shunt infections (within 6 months after implant). AISC is more effective in high-risk population (OR, 0.24;95% CI, 0.14-0.40; p=0.60; I2=0%) than in general patient population. Conclusion : The results of meta-analysis indicated that AISC is an effective method for reducing shunt infection. We recommend that AISC should be considered for use in infants and high-risk groups. For adult patients, the choice for AISC could be determined based on the treatment cost.

Zhu, Wen-Wen,Kang, Li,Gao, Ya-Ping,Hei, Yan,Dong, Jie,Liu, Yu,Xiao, Li-Hua,Yang, Guang Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.11

Objective: To investigate whether the expression level of valosin-containing protein (VCP) is correlated with the prognosis of primary orbital mucosa-associated lymphoid tissue (MALT) lymphoma. Methods: VCP expression in 58 samples from primary orbital MALT lymphoma patients was determined by immunohistochemisty using monoclonal antibodies. Correlations between VCP expression level and prognosis were clarified by statistical analysis. Results: It was found that the percentage of VCP positive cells in samples of primary orbital MALT lymphoma ranged from 32% to 95%. The samples were divided into two groups (level 1 and level 2) according to the median value (45%) of the percentage of VCP positive cells. It was found that the expression level of VCP was significantly correlated with recurrence (P=0.003) and tumor size (P=0.008). At the same time, the 5-year disease-free and overall survival rate of patients of level 1 was significantly better than that of level 2 (P=0.001; P=0.032). There was no observed correlation between the expression level of VCP and other clinical features. Conclusion: VCP could be a useful marker for predicting the prognosis of primary orbital MALT lymphoma.

현대 중국에서의 법 이해에 대한 고찰 -중국의 법 개념의 원류(源流)를 추적하는 작업의 일환으로-

강광문 ( Guang Wen Jiang ) 서울대학교 법학연구소 2015 서울대학교 法學 Vol.56 No.3

본 논문은 현대 중국에서 ``법``이 어떻게 정의(定義)되고 있고 중국식 법 인식의 기원(起源)이 어디에 있는가를 추적하는 데 그 목적이 있다. 논문은 중국에서 ``법``의 몇몇 사용례를 검토한 후, 이러한 법 이해의 배후에는 두 가지 사상적 계보, 즉 전통적인 중국의 법사상과 1949년 이후 구소련을 통해 들어온 마르크스주의 법 이해의 영향이 있다고 분석하였다. 서양의 일반적인 법인식과 비교해 볼 경우, 중국식 법 이해에는 강한 법실증주의의 경향, 법에 대한 도구론적 이해 및 이른바 ``rule of law``와는 다른 ``法治``의 관념등의 특징이 보인다. 법 개념에 대한 이와 같은 고찰은, 중국에서 현재 일어나고 있는 각종 법제 현상, 나아가 현대 중국 사회를 이해하는 데에도 도움이 될 것이다. The purpose of this article is to define ``the law (fa)`` in modern China and trace the origin of the Chinese common understanding of law. After reviewing several examples of ``the law`` in China, the author analyzed that the Chinese understanding of law is under the influence of two ideological pedigrees, that is, traditional Chinese legal ideology and Marxist law through the former Soviet Union after 1949. Compared with the western legal cognition, the Chinese understanding of law has strong tendency of legal positivism and instrumental understanding of law. Moreover, the concept of ``法治= fazhi`` in China is different from ``rule of law``. The study of such legal concept helps to understand current status of legal system and the modern Chinese society.

Therapeutic Regimens and Prognostic Factors of Brain Metastatic Cancers

Song, Wen-Guang,Wang, Yi-Feng,Wang, Rui-Lin,Qu, Yin-E,Zhang, Zhi,Li, Guo-Zhong,Xiao, Ying,Fang, Fang,Chen, Hong Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.2

Objective: This work aims to investigate the therapeutic regimen of brain metastatic cancers and the relationship between clinical features and prognosis. Methods: Clinical data of 184 patients with brain metastatic cancers were collected and analysed for the relationship between survival time and age, gender, primary diseases, quantity of brain metastatic foci, their position, extra cranial lesions, and therapeutic regimens. Results: The average age of onset was 59.1 years old. The median survival time (MST) was 15.0 months, and the patients with breast cancer as the primary disease had the longest survival time. Females had a longer survival time than males. Patients with meningeal metastasis had extremely short survival time. Those with less than 3 brain metastatic foci survived longer than patients with more than 3. The MST of patients receiving radiotherapy only and the patients receiving chemotherapy only were all 10.0 months while the MST of patients receiving combination therapy was 16.0 months. Multiple COX regression analysis demonstrated that gender, primary diseases, and quantity of brain metastatic foci were independent prognostic factors for brain metastatic cancers. Conclusions: Chemotherapy is as important as radiotherapy in the treatment of brain metastatic cancer. Combination therapy is the best treatment mode. Male gender, brain metastatic cancers originating in the gastrointestinal tract, more than 3 metastatic foci, and involvement of meninges indicate a worse prognosis.
