자아초월 정신의학이 체계화되면서 영성(spirituality)은 인성의 한 부분이라는 이론이 대두되었는데 이 영성은 정신건강에 큰 영향을 미친다고 했다. 인간의 성향 중 영적 안녕 정도를 파악하여 그 정도가 정신건강 중 허위성 경향, 정신병적 경향 및 불안과 우울 경향 등에 어떠한 영향을 미치는지를 조사하고저 본 연구를 실시하였다. 대상은 중국의 연변 조선족 자치구에 거주하는 여성 400명을 대상으로 하여 한국판 영적 안녕척도를 사용하여 영적 안녕정도를 파악하였다. 영적 안녕척도의 총점과 이 척도의 2개 하위 척도인 종교적 안녕과 실존적 안녕 척도 양자로 평가한 성적이 불안-우울통합척도와 정신분열증 척도 및 허위성 척도로 평가한 성적에 미치는 영향을 검증하기 위하여 상관관계분석 및 회기분석을 실시하였다. 그 결과는 다음과 같다. 1) 영적 안녕척도로 평가한 조선족 여성의 총점은 68.29로 한국의 기독교 여성이 평가한 100.65보다 훨씬 낮은 점수였다. 2) 불안·우울통합척도로 평가한 총점은 44.88로 연변노인이 평가한 점수와 일개지역의 한국농촌주민이 평가한 점수와 비슷한 결과였다. 3) 허위성 척도로 평가한 성적은 평균 74.57로 70점 이상이 86%(344명)이었으나 영적 안녕 성적과 허위성 성적 간에는 유의한 상관이 없었다. 4) 영적 안녕총점은 정신분열증 척도로 평가한 정신병적 경향에 유의한 영향을 미치지 않았으나 종교적 안녕하위척도의 성적은 정신병적 경향을 높여준데 비하여 실존적 안녕하위척도의 성적은 정신병적 경향을 낮게 해주었다. 5) 영적 안녕척도의 총점 및 두 하위척도인종교적 안녕과 실존적 안녕은 불안과 우울에유의한 상관을 보였는데 영적 안녕총점이 높을수록 불안·우울 총점이 다소 낮아지는 경향을 보였다. 6) 종교적 안녕 하위척도와 불안과 우울과의 관계는 종교적 안녕점수가 높을수록 불안과 우울을 각각 다소 유의하게 높여주었으며 이에 비하여 실존적 안녕하위척도와 불안과 우울과의 관계는 실존적 안녕정도가 높을수록 불안 및 우울점수는 유의하게 낮아졌다. 이와 같은 성적을 미루어볼 때 연변에 거주하는 조선족 여성이 평가한 영적 안녕정도는 정신병적 경향과 불안 및 우울에 유의한 상관을 보였으면 이 척도의 하위 척도인 종교적 안녕정도는 정신건강에 부정적인 영향을 미치는 반면 실존적 안녕정도는 정신건강에 긍정적 영향을 미친 결과로 평가되었다. 이러한 결과는 공산주의 사회에서 실존적 안녕은 긍정적인 가치관으로 평가되는 반면 종교적 안녕은 정신건강에 부정적으로 작용한 것을 입증해 주었다고 하겠다. Background: Spirituality has been an important part of Transpersonal Psychology and is believed to have a large effect on the mental health because it has been systematized. The aim of this study was to determine the level of spiritual disposition on human beings along with its effects on one's mental health. Materials and Methods: The study targeted 400 women residing in Youn-Gil city of JiLin Prov., which is a district of the Cho-Sun tribe in China. Their spiritual well-being was studied using the Spiritual Well-being Scale-Korean Version. The spiritual well-being scale consists of 2 sub-scales of religious well-being and existential well-being. The study was evaluated using a lie scale, psychotic trend, and a combined anxiety-depression scale. The results were considered to be factors of one's mental health. The correlation between the spiritual well-being and each tendency was analyzed by regression analysis. Results: The total score of the Cho-Sun tribal women according to the spiritual well-being scale was 68.29 which was much less than the 100.65 of Korean Christian women. There was no significant correlation between the spiritual well-being and the Lie trend. However, it was found that 86%(344) of Cho-Sun tribal women scored above 70 in the Lie trend with a mean score of 74.57 which is higher than normal populations. Regarding the correlation between the spiritual well-being and psychotic trend, the psychotic trend became significantly higher when the religious well-being was at a high level. On the other hand, the psychotic trend became significantly lower when the existential well-being was at a high level. Regarding the correlation between the spiritual well-being and anxiety, the anxiety was significantly higher when the religious well-being was at a high level. However, the anxiety level was significantly low when the existential well-being was at a high level. Regarding the correlation between the spiritual well-being and depression, the depression level was somewhat significantly high when the religious well-being was at a high level. However, the depression level was significantly low when the existential well-being was at a high level. Conclusion: This study evaluated the effects of spiritual well-being on a person's mental health among Cho-Sun tribal women in Youn-Gil city of JiLIn Prov., P.R. of China. The results found that the religious well-being, which is a sub-scale of spiritual well-being, had negative effects while the existential well-being had positive effects on the mental health. These results proved that a person's religious disposition had negative effects on their mental health in a communitarian society.

Objective: In the present study, we aimed to investigate the effects of enzymolysis fermentation of Chinese herbal medicines (CHMs) on egg production performance, egg quality, lipid metabolism, serum reproductive hormone levels, and the mRNA expression of the ovarian hormone receptor of laying hens in the late-laying stage. Methods: A total of 360 Hy-Line Brown laying hens (age, 390 days) were randomly categorized into four groups. Hens in the control (C) group were fed a basic diet devoid of CHMs, the crushed CHM (CT), fermented CHM (FC), and enzymatically fermented CHM (EFT) groups received diets containing 2% crushed CHM, 2% fermented CHM, and 2% enzymatically fermented CHM, respectively. Results: Compared with crushed CHM, the acid detergent fiber, total flavonoids, and total saponins contents of fermented CHM showed improvement (p<0.05); furthermore, the neutral and acid detergent fiber, total flavonoids, and total saponins contents of enzymatically fermented CHM improved (p<0.05). At 5 to 8 weeks, hens in the FC and EFT groups showed increased laying rates, haugh unit, albumin height, yolk color, shell thickness, and shell strength compared with those in the C group (p<0.05). Compared with the FC group, the laying rate, albumin height, and Shell thickness in the EFT group was increased (p<0.05). Compared with the C, CT, and FC groups, the EFT group showed reduced serum total cholesterol and increased serum luteinizing hormone levels and mRNA expressions of follicle stimulating hormone receptor and luteinizing hormone receptor (p<0.05). Conclusion: These results indicated that the ETF group improved the laying rate and egg quality and regulated the lipid metabolism in aged hens. The mechanism underlying this effect was likely related to cell wall degradation of CHM and increased serum levels of luteinizing hormone and mRNA expression of the ovarian hormone receptor.

Marine microalgae have been widely applied in cosmaceuticals, nutraceuticals, and functional foods. In the present study, we first investigated the hepatoprotective effects of peptide purified from microalgae, Isochrysis zhanjiangensis on HepG2 cells alcoholic injury. I. zhanjiangensis was hydrolyzed utilizing chymotrypsin, trypsin, pepsin, and by vitro gastrointestinal digestion. Among hydrolysates, the gastrointestinal hydrolysate showed relatively high free radical scavenging ability preliminarily and was purified with following sequential chromatography methods. The amino acid sequence and molecular mass of the purified peptide from I. zhanjiangensis (PIZ) was identified as Asn-Asp-Ala-Glu-Tyr-Gly-Ile-Cys-Gly-Phe (NDAEYGICGF; MW, 1088.16 Da) via Q-TOF ESI/MS. Additionally, PIZ attenuated ethanol-induced cytotoxicity and inhibited the production of intracellular reactive oxygen species by DCFH-DA assay. Western blot results showed that superoxide dismutase (SOD) and glutathione (GSH) levels up-regulated with PIZ treatment before alcohol exposure while gamma-glutamyltransferase (GGT) protein expression down-regulated. These results provide an opportunity to discover new highly active peptide against alcohol toxicity in HepG2 cells.

Mitogen-Activated Protein Kinase Signal Transduction in Solid Tumors

Lei, Yuan-Yuan,Wang, Wei-Jia,Mei, Jin-Hong,Wang, Chun-Liang Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.20

Mitogen-activated protein kinase (MAPK) is an important signaling pathway in living beings in response to extracellular stimuli. There are 5 main subgroups manipulating by a set of sequential actions: ERK(ERK1/ERK2), c-Jun N(JNK/SAPK), p38 MAPK($p38{\alpha}$, $p38{\beta}$, $p38{\gamma}$ and $p38{\delta}$), and ERK3/ERK4/ERK5. When stimulated, factors of upstream or downstream change, and by interacting with each other, these groups have long been recognized to be related to multiple biologic processes such as cell proliferation, differentiation, death, migration, invasion and inflammation. However, once abnormally activated, cancer may occur. Several components of the MAPK network have already been proposed as targets in cancer therapy, such as p38, JNK, ERK, MEK, RAF, RAS, and DUSP1. Among them, alteration of the RAS-RAF-MEK-ERK-MAPK(RAS-MAPK) pathway has frequently been reported in human cancer as a result of abnormal activation of receptor tyrosine kinases or gain-of-function mutations in genes. The reported roles of MAPK signaling in apoptotic cell death are controversial, so that further in-depth investigations are needed to address these controversies. Based on an extensive analysis of published data, the goal of this review is to provide an overview on recent studies about the mechanism of MAP kinases, and how it generates certain tumors, as well as related treatments.

De Peng Yuan,Xiao Feng Xu,Hong Woo-Jong,Si Ting Wang,Xin Tong Jia,Yang Liu,Shuang Li,Zhi Min Li,Qian Sun,Qiong Mei,Shuai Li,정기홍,Song Hong Wei,Yuan Hu Xuan 한국식물생명공학회 2020 Plant biotechnology reports Vol.14 No.5

Sheath blight disease (ShB) severely afects rice production; however, the details of defense against ShB remain unclear. To understand the rice defense mechanism against ShB, an RNA sequencing analysis was performed using Rhizoctonia solani inoculated rice leaves after 48 h of inoculation. Among them, 3417 genes were upregulated and 2532 were downregulated when compared with the control group (>twofold or<1/2). In addition, the diferentially expressed genes were classifed via Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and MapMan analyses. Fifty-nine GO terms and seven KEGG pathways were signifcantly enriched. A MapMan analysis demonstrated that the phytohormone and metabolic pathways were signifcantly altered. Interestingly, the expression levels of 359 transcription factors, including WRKY, MYB, and NAC family members, as well as 239 transporter genes, including ABC, MFS, and SWEET, were signifcantly changed in response to R. solani AG1-IA inoculation. Additionally, OsWRKY53 and OsAKT1 negatively regulate the defense response in rice against R. solani via gain of function study for OsWRKY53 and loss of function study for OsAKT1, respectively. Furthermore, several diferentially expressed genes contain R. solani-responsive cis acting regulatory elements in their promoter regions. Taken together, our analyses provide valuable information for the additional study of the defense mechanisms against ShB, and the candidate genes identifed in this study will be useful resource for future breeding to enhance resistance against ShB.

<P><B>Abstract</B></P> <P>An emulsion-directed assembly and adsorption approach has been used to fabricate composite films of polystyrene-b-poly(acryl acid)-b-polystyrene (PS-b-PAA-b-PS) and Eu<SUP>3+</SUP> and La<SUP>3+</SUP> ions at the planar liquid/liquid interface of the polymer DMF/chloroform (1:1, v/v) mixed solution (lower phase) and aqueous solutions of the corresponding salts (upper phase). The lower phase gradually transformed to a water-in-oil (W/O) emulsion via spontaneous emulsification due to the “ouzo effect”. Polymer molecules and the metal ions assembled around emulsion droplets that adsorbed at the planar liquid/liquid interface at last, resulting in formation of composite films. The film morphologies and structures depend on Ln<SUP>3+</SUP> ions: polymer/Eu<SUP>3+</SUP> composite films were foam films composed of microcapsules ranging in size from several hundreds of nanometers to micrometers, while polymer/La<SUP>3+</SUP> composite films were composed of hollow spheres several tens of nanometers in size. Fourier transform infrared (FTIR) spectra revealed that the coordination modes of carboxyl groups to Eu<SUP>3+</SUP> and La<SUP>3+</SUP> were bridging bidentate and ionic, respectively, in the two types of composites. These results indicate that stable microcapsules can be fabricated around droplets for polymer/Eu<SUP>3+</SUP> systems, while microcapsules of polymer/La<SUP>3+</SUP> are unstable. This leads to different film morphologies and structures. Compositions of these films were characterized using energy-dispersive spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS). In addition, foam films of polymer/Eu<SUP>3+</SUP>/2,2′-bipyridine (bpy) were fabricated using this approach, and their photoluminescence properties were investigated.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Composite films of block copolymer/Ln<SUP>3+</SUP> were fabricated at liquid/liquid interfaces. </LI> <LI> Eu<SUP>3+</SUP> and La<SUP>3+</SUP> have great effects on morphologies and microstructures of the films. </LI> <LI> Polymer/Eu<SUP>3+</SUP> and polymer/Eu<SUP>3+</SUP>/bpy films exhibit good luminescent properties. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Efficacy and Safety of Neurokinin-1 Receptor Antagonists for Prevention of Chemotherapy-Induced Nausea and Vomiting: Systematic Review and Meta-analysis of Randomized Controlled Trials

Yuan, Dong-Mei,Li, Qian,Zhang, Qin,Xiao, Xin-Wu,Yao, Yan-Wen,Zhang, Yan,Lv, Yan-Ling,Liu, Hong-Bin,Lv, Tang-Feng,Song, Yong Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.4

Objectives: Can addition of neurokinin-1 receptor antagonists (NK1-RAs) be considered as an ideal strategy for the prevention of chemotherapy-induced nausea and vomiting (CINV)? Researchers differ on this question. Materials and Methods: Electronic databases were searched for randomized control trials (RCTs) that evaluated the effectiveness and safety of NK1-RAs in preventing CINV. The primary end point was complete response (CR) in the acute, delayed, and overall phases after chemotherapy. Subgroup analyses evaluated the types of NK1-RAs, routines of administration, types of malignancies, regimens used in combination with NK1-RAs, and age of patients included in the studies. The incidences of different types of adverse events were also extracted to estimate the safety of NK1-RAs. Results: A total of 38 RCTs involving 13,923 patients were identified. The CR rate of patients receiving NK-RAs was significantly higher than patients in the control groups during overall phase (70.8% vs 56.0%, P<0.001), acute phase (85.1% vs 79.6%, P<0.001), and delayed phase (71.4% vs 58.2%, P<0.001). There were three studies including patients of children or adolescents, the CR rate was also significantly higher in the treatment group (overall phase: OR=2.807, P<0.001; acute phase: OR=2.863, P =0.012; delayed phase: OR=2.417, P<0.001). For all the other outcomes, patients in the NK1-RAs groups showed improvements compared to the control groups (incidence of nausea: 45.2% vs 45.9%, P<0.001; occurrence of vomiting: 22.6% vs 38.9%, P<0.001; usage of rescue drugs: 23.5% vs 34.1%, P<0.001). The pooled side effects from NK1-RAs did not significantly differ from previous reports and the toxicity rates in patients less than eighteen years old also did not diff between the two groups (P=0.497). However, we found that constipation and insomnia were more common in the patients of control groups, whereas diarrhea and hiccups were more frequently detected in patients receiving NK1-RAs. Conclusions: NK1-RAs improved the CR rate of CINV. They are effective for both adults and children. The use of NK1-RAs might be associated with the appearance of diarrhea and hiccups, while decreasing the possibility of constipation and insomnia.

Antiviral activity of Herba Patrinea (a Chinese medicinal herb) against respiratory syncytial virus in vitro

Li, Hong-Yuan,Li, Shan-Shan,Liu, Dian-Li,Dong, Yan-Mei,Tian, Wen-Jing Kyung Hee Oriental Medicine Research Center 2003 Oriental pharmacy and experimental medicine Vol.3 No.2

Respiratory syncytial virus (RSV) has long been considered an important cause of severe lower respiratory tract infection in infants and young children throughout the world. Unfortunately, no effective treatment of RSV exists. Therefore, New agents are needed to reduce the impact of RSV. We have studied the anti-viral effect of traditional Chinese midicinal herbs for over ten years and find Herba Patrinea (a Chinese medicinal herb) has the anti-RSV effect in vitro. In this study, the Herba Patrinea was extracted with hot water, condensed and sterilized. The cytotoxicity of the aqueous extract was tested by adding the diluted extract directly to HeLa cells and its effect on anti-RSV was estimated by the CPEI assay. As a result, the median cytotoxic concentration $(CC_{50})$ of Herba Patrinea was 32 mg/ ml by morphological observation, the median effective concentration (50% effective concentration, $EC_{50}$) of the Herba Patrinea against replication of the Long strain of RSV in HeLa cells were 1.25 mg/ml. The selectivity index $(SI=CC_{50}/EC{50})$ is 25.6. Moreover, Herba Patrinea gave a dose-dependent response in inhibiting RSV. In time of addition experiment, Herba Patrinea inhibited replication of RSV in HeLa cells when it was added at 0h, 2h, and 4h after virus infection. In summary, the results of this study suggest Herba Patrinea may be a novel anti-RSV drug and it is worthy of further studying.

Dynamics of oppositely charged carriers in a metal/coupled poly(p-phenylene vinylene) chains/metal structure

Dong-Mei Li,Yuan Li,Hai-Hong Li,Desheng Liu 한국물리학회 2011 Current Applied Physics Vol.11 No.2

By using the extended version of the Su-Schrieffer-Heeger (SSH) tight-binding model and a non-adiabatic dynamic evolution method, we present a study of the dynamic process of oppositely charged carriers in a metal/two coupled poly(p-phenylene vinylene) chains/metal structure. Electrons and holes can be injected into the polymer chains from metal electrodes by applying voltage biases. The behavior of the injected charged carriers depends closely on the electric field and the interchain coupling. The moderate intensity of electric field is in favor of forming stable wave packets, and the charge carriers localized in wave packets occur to transport, hopping, collide and recombine. With increasing the electric field, part of the carriers can be ejected into the metal electrodes.
