        Case Reports : Sturge-Weber Syndrome

        ( Ling Chen ),( Jin Jin Wu ),( Min Hui Xu ),( Nian Chen ),( Ya Dong Yang ) 대한피부과학회 2011 Annals of Dermatology Vol.23 No.4

        Sturge-Weber syndrome (SWS) is a neurocutaneous syndrome, characterized by the association of facial port-wine hemangiomas in the trigeminal nerve distribution area, with vascular malformation(s) of the brain (leptomeningeal angioma) with or without glaucoma. Herein, we reported Sturge-Weber syndrome in a 50-year-old man, who presented port-wine hemangiomas and epilepsy. In this case, the patient`s epilepsy episodes from his first year of life had been ignored and separated from the entity of SWS by his physicians, which led to delayed treatment. This case illustrates the importance of careful examination of patients of any age with hemangiomas in the trigeminal nerve with concomitant episodes of epilepsy. In such cases, there should be yearly neuroimaging screenings to guaranteed early interdisciplinary interventions from the time of definite diagnosis. (Ann Dermatol 23(4) 551~553, 2011)

        Mitochondrial citrate accumulation drives alveolar epithelial cell necroptosis in lipopolysaccharide-induced acute lung injury

        Yang Hui-Hui,Jiang Hui-Ling,Tao Jia-Hao,Zhang Chen-Yu,Xiong Jian-Bing,Yang Jin-Tong,Liu Yu-Biao,Zhong Wen-Jing,Guan Xin-Xin,Duan Jia-Xi,Zhang Yan-Feng,Liu Shao-Kun,Jiang Jian-Xin,Zhou Yong,Guan Cha-Xi 생화학분자생물학회 2022 Experimental and molecular medicine Vol.54 No.-

        Necroptosis is the major cause of death in alveolar epithelial cells (AECs) during acute lung injury (ALI). Here, we report a previously unrecognized mechanism for necroptosis. We found an accumulation of mitochondrial citrate (citratemt) in lipopolysaccharide (LPS)-treated AECs because of the downregulation of Idh3α and citrate carrier (CIC, also known as Slc25a1). shRNA- or inhibitor–mediated inhibition of Idh3α and Slc25a1 induced citratemt accumulation and necroptosis in vitro. Mice with AEC-specific Idh3α and Slc25a1 deficiency exhibited exacerbated lung injury and AEC necroptosis. Interestingly, the overexpression of Idh3α and Slc25a1 decreased citratemt levels and rescued AECs from necroptosis. Mechanistically, citratemt accumulation induced mitochondrial fission and excessive mitophagy in AECs. Furthermore, citratemt directly interacted with FUN14 domain-containing protein 1 (FUNDC1) and promoted the interaction of FUNDC1 with dynamin-related protein 1 (DRP1), leading to excessive mitophagy-mediated necroptosis and thereby initiating and promoting ALI. Importantly, necroptosis induced by citratemt accumulation was inhibited in FUNDC1-knockout AECs. We show that citratemt accumulation is a novel target for protection against ALI involving necroptosis.

      • Asparagus Polysaccharide and Gum with Hepatic Artery Embolization Induces Tumor Growth and Inhibits Angiogenesis in an Orthotopic Hepatocellular Carcinoma Model

        Weng, Ling-Ling,Xiang, Jian-Feng,Lin, Jin-Bo,Yi, Shang-Hui,Yang, Li-Tao,Li, Yi-Sheng,Zeng, Hao-Tao,Lin, Sheng-Ming,Xin, Dong-Wei,Zhao, Hai-Liang,Qiu, Shu-Qi,Chen, Tao,Zhang, Min-Guang Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.24

        Liver cancer is one of leading digestive malignancies with high morbidity and mortality. There is an urgent need for the development of novel therapies for this deadly disease. It has been proven that asparagus polysaccharide, one of the most active derivates from the traditional medicine asparagus, possesses notable antitumor properties. However, little is known about the efficacy of asparagus polysaccharide as an adjuvant for liver cancer chemotherapy. Herein, we reported that asparagus polysaccharide and its embolic agent form, asparagus gum, significantly inhibited liver tumor growth with transcatheter arterial chemoembolization (TACE) therapy in an orthotopic hepatocellular carcinoma (HCC) tumor model, while significantly inhibiting angiogenesis and promoting tumor cell apoptosis. Moreover, asparagine gelatinous possessed immunomodulatory functions and showed little toxicity to the host. These results highlight the chemotherapeutic potential of asparagus polysaccharide and warrant a future focus on development as novel chemotherapeutic agent for liver cancer TACE therapy.

        Mesenchymal Stem Cell Secreted-Extracellular Vesicles are Involved in Chondrocyte Production and Reduce Adipogenesis during Stem Cell Differentiation

        Tsai Yu-Chen,Cheng Tai-Shan,Liao Hsiu-Jung,Chuang Ming-Hsi,Chen Hui-Ting,Chen Chun-Hung,Zhang Kai-Ling,Chang Chih-Hung,Lin Po-Cheng,Huang Chi-Ying F. 한국조직공학과 재생의학회 2022 조직공학과 재생의학 Vol.19 No.6

        BACKGROUND: Extracellular vesicles (EVs) are derived from internal cellular compartments, and have potential as a diagnostic and therapeutic tool in degenerative disease associated with aging. Mesenchymal stem cells (MSCs) have become a promising tool for functional EVs production. This study investigated the efficacy of EVs and its effect on differentiation capacity. METHODS: The characteristics of MSCs were evaluated by flow cytometry and stem cell differentiation analysis, and a production mode of functional EVs was scaled from MSCs. The concentration and size of EVs were quantitated by Nanoparticle Tracking Analysis (NTA). Western blot analysis was used to assess the protein expression of exosomespecific markers. The effects of MSC-derived EVs were assessed by chondrogenic and adipogenic differentiation analyses and histological observation. RESULTS: The range of the particle size of adipose-derived stem cells (ADSCs)- and Wharton’s jelly -MSCs-derived EVs were from 130 to 150 nm as measured by NTA, which showed positive expression of exosomal markers. The chondrogenic induction ability was weakened in the absence of EVs in vitro. Interestingly, after EV administration, type II collagen, a major component in the cartilage extracellular matrix, was upregulated compared to the EV-free condition. Moreover, EVs decreased the lipid accumulation rate during adipogenic induction. CONCLUSION: The results indicated that the production model could facilitate production of effective EVs and further demonstrated the role of MSC-derived EVs in cell differentiation. MSC-derived EVs could be successfully used in cell-free therapy to guide chondrogenic differentiation of ADSC for future clinical applications in cartilage regeneration.

        Combination of Tumor Volume and Epstein-Barr Virus DNA Improved Prognostic Stratification of Stage II Nasopharyngeal Carcinoma in the Intensity Modulated Radiotherapy Era: A Large-Scale Cohort Study

        Qiu-Yan Chen,Shao-Yan Guo,Lin-Quan Tang,Tong-Yu Lu,Bo-Lin Chen,Qi-Yu Zhong,Meng-Sha Zou,Qing-Nan Tang,Wen-Hui Chen,Shan-Shan Guo,Li-Ting Liu,Yang Li,Ling Guo,Hao-Yuan Mo,Rui Sun,Dong-Hua Luo,Chong Zha 대한암학회 2018 Cancer Research and Treatment Vol.50 No.3

        Purpose Little is known about combination of the circulating Epstein-Barr viral (EBV) DNA and tumor volume in prognosis of stage II nasopharyngeal carcinoma (NPC) patients in the intensity modulated radiotherapy (IMRT) era. We conducted this cohort study to evaluate the prognostic values of combining these two factors. Materials and Methods By Kaplan-Meier, we compare the differences of survival curves between 385 patients with different EBV DNA or tumor volume levels, or with the combination of two biomarkers mentioned above. Results Gross tumor volume of cervical lymph nodes (GTVnd, p < 0.001) and total tumor volume (GTVtotal, p < 0.001) were both closely related to pretreatment EBV DNA, while gross tumor volume of nasopharynx (GTVnx, p=0.047) was weakly related to EBV DNA. EBV DNA was significantly correlated with progress-free survival (PFS, p=0.005), locoregional-free survival (LRFS, p=0.039), and distant metastasis-free survival (DMFS, p=0.017), while GTVtotal, regardless of GTVnx and GTVnd, had a significant correlation with PFS and LRFS. The p-values of GTVtotal for PFS and LRFS were 0.008 and 0.001, respectively. According to GTVtotal and pretreatment EBV DNA level, patients were divided into a low-risk group (EBV DNA 0 copy/mL, GTVtotal < 30 cm3; EBV DNA 0 copy/mL, GTVtotal  30 cm3; or EBV DNA > 0 copy/mL, GTVtotal < 30 cm3) and a high-risk group (EBV DNA > 0 copy/mL, GTVtotal  30 cm3). When patients in the low-risk group were compared with those in the high-risk group, 3-year PFS (p=0.003), LRFS (p=0.010), and DMFS (p=0.031) rates were statistically significant. Conclusion Pretreatment plasma EBV DNA and tumor volume were both closely correlated with prognosis of stage II NPC patients in the IMRT era. Combination of EBV DNA and tumor volume can refine prognosis and indicate for clinical therapy.

      • The Effect of a Scenario-Based Spiritual Care Course on Spiritual Care Competence among Clinical Nurses

        Suh-Ing Hsieh,Li-Ling Hsu,Hui-Ling Lin,Chen-Yi Kao,Yi-Ping Tseng,Li-Yun Szu,Ching-Yun Lee,Lun-Hui Ho,Shu-Ling Yeh,Shu-Hua Kao,Yen-Fang Chou,Tzu-Hsin Huang 한국성인간호학회 2021 성인간호학회 학술대회 Vol.2021 No.8

        Aim(s): Clinical nurses are facing patients’ biopsychosocial and spiritual problems at diverse clinical settings, but they are lack of knowledge, skills, and confidence on providing spiritual care. However, no studies adopted simulated educational program and objective structure clinical examination (OSCE) to educate nurses and to assess the outcomes. Therefore, this study was to validate the effect of a scenario-based spiritual care course on spiritual care competence in clinical nurses. Methods: This non-equivalent quasi-experimental study with a pre-test and two post-tests (end of the intervention and three months later) was conducted between August 2019 and February 2021 (11 sessions). The recruitment posters with a QR code were distributed to different units at three branches of a large medical institute for recruiting clinical nurses, who provided direct patient care. The attendees of one-day scenario-based spiritual care course are the experimental group (n=53) and the control group (n=85) was matched with the experimental group (1:1-3 ratio) by similar units, ages, working experience, and clinical ladder. Instruments include basic information, self-evaluated and head nurses evaluated spiritual care competence scale (SCCS), spiritual perspective scale (SPS), and spiritual care perspective scale-revised (SCPSR) for both groups and reflective log, course satisfaction scale, OSCE checklist, and standardized patient feedback scale for the experimental group. The data were analyzed using descriptive statistics, repeated measures ANOVA, linear regression, and paired t test. Results: After controlling for pre-test scores and interest in attending spirituality/spiritual care, the experimental group showed significant higher SPS (p=0.012) and self-evaluated SCCS (p=0.002) and lower SCPSR (p=0.015) than the control group at the 2nd post-test. Repeated measure ANOVA also showed significant within-subject effects across three time points of the experimental group on SPS (p<0.001), SCPSR (p<0.001), and self-evaluated SCCS (p<0.001), but paired t test showed non-significant differences on SPS, SCPSR, and self-evaluated SCCS between pre-test and post-test with an exception of head nurse evaluated SCCS (p=0.035). The mean overall course satisfaction of the experimental group was 4.34±0.62. The mean global performance of OSCE was 3.40±0.91 and the majority of experimental group was pass (43.4%) and good (35.8%). 64.5% and 26.1% of standardized patients were partial and strongly agreed with examinees’ performance in spiritual care assessment respectively. Conclusions: The scenario-based spiritual care course is effectively to enhance clinical nurses’ spiritual care competence. It may cultivate clinical preceptors with better spiritual care pedagogy through simulation and OSCE for bedside teaching of nurse post-graduate year.

      • Folate Deficiency and FHIT Hypermethylation and HPV 16 Infection Promote Cervical Cancerization

        Bai, Li-Xia,Wang, Jin-Tao,Ding, Ling,Jiang, Shi-Wen,Kang, Hui-Jie,Gao, Chen-Fei,Chen, Xiao,Chen, Chen,Zhou, Qin Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.21

        Fragile histidine triad (FHIT) is a suppressor gene related to cervical cancer through CpG island hypermethylation. Folate is a water-soluble B-vitamin and an important cofactor in one-carbon metabolism. It may play an essential role in cervical lesions through effects on DNA methylation. The purpose of this study was to observe effects of folate and FHIT methylation and HPV 16 on cervical cancer progression. In this study, DNA methylation of FHIT, serum folate level and HPV16 status were measured using methylation-specific polymerase chain reaction (MSP), radioimmunoassay (RIA) and polymerase chain reaction (PCR), respectively, in 310 women with a diagnosis of normal cervix (NC, n=109), cervical intraepithelial neoplasia (CIN, n=101) and squamous cell carcinoma of the cervix (SCC, n=101). There were significant differences in HPV16 status (${\chi}^2=36.64$, P<0.001), CpG island methylation of FHIT (${\chi}^2=71.31$, P<0.001) and serum folate level (F=4.57, P=0.011) across the cervical histologic groups. Interaction analysis showed that the ORs only with FHIT methylation (OR=11.47) or only with HPV 16 positive (OR=4.63) or with serum folate level lower than 3.19ng/ml (OR=1.68) in SCC group were all higher than the control status of HPV 16 negative and FHIT unmethylation and serum folate level more than 3.19ng/ml (OR=1). The ORs only with HPV 16 positive (OR=2.58) or with serum folate level lower than 3.19ng/ml (OR=1.28) in CIN group were all higher than the control status, but the OR only with FHIT methylation (OR=0.53) in CIN group was lower than the control status. HPV 16 positivity was associated with a 7.60-fold increased risk of SCC with folate deficiency and with a 1.84-fold increased risk of CIN. The patients with FHIT methylation and folate deficiency or with FHIT methylation and HPV 16 positive were SCC or CIN, and the patients with HPV 16 positive and FHIT methylation and folate deficiency were all SCC. In conclusion, HPV 16 infection, FHIT methylation and folate deficiency might promote cervical cancer progression. This suggests that FHIT may be an effective target for prevention and treatment of cervical cancer.

        Molecule-based electrorheological material with luminescence property

        Chen, Ming-Xing,Liao, Fu-Hui,Shang, Yan-Li,Jia, Yun-Ling,Li, Jun-Ran 한국유변학회 2013 Korea-Australia rheology journal Vol.25 No.1

        Molecule-based electrorheological (ER) materials with luminescence property, based on ${\beta}$-cyclodextrin [($C_6O_5H_{10})_7$, ${\beta}$-CD] inclusion compounds between ${\beta}$-CD (host) and the rare earth (RE) (RE=Tb, Eu) complex (guest), have been synthesized as a novel type of ER materials using ${\beta}$-CD, $Tb(NO_3)_3$, $Eu(NO_3)_3$, sulphosalicylic acid ($C_7H_6O_6S{\cdot}2H_2O$, SSA) and m-phthalic acid ($C_8H_6O_4$, MPA) as original materials. The composition, ER performance, luminescence property and dielectric property of the materials have been studied. The results show that the rare earth complex in the cavity of ${\beta}$-CD may enhance the ER performance of ${\beta}$-CD, and the complex (Tb-SSA) of $Tb^{3+}$ can improve more effectively the ER activity of ${\beta}$-CD than that (Eu-MPA) of $Eu^{3+}$ among both of the complexes. The composition and structure are the dominant factors in improving the ER effect. The fluorescence intensity, fluorescence lifetime and emission quantum yield of the particle materials and their suspensions in silicone oil have been tested, and fine luminescence performance has been detected. The material with ER activity and luminescence performance is a novel multifunctional material which would have wide application prospect.
