Background: Emergency department (ED) overcrowding is a problem in many countries including Taiwan. Access block refers to a situation where patients in the emergency department requiring inpatient care are unable to gain access to appropriate hospital beds within a reasonable time frame (more than 8 hours total time in the emergency department). Access block is one major reason of ED overcrowding. Methods: A new holistic care unit was established in our medical center in Taiwan in July 2012, with the attending physicians including internal medicine physicians and a neurologist. The patients who required hospitalized treatment were referred to internal medicine physicians in the emergency department. The new department was comprised of seven experienced medical attending physician to take care of the patients directly, with 8-hour duty work shifts within 24 hours, in collaboration with emergency physicians, radiologists, nurses, social workers and case managers to form a team. This team had similar three-shift work duty, education and training programs, and they shared medical devices and resources. If beds in the intensive care unit or ward are not available immediately, procedures and treatment can be performed in the holistic care unit. The pediatric patients were excluded from this study. Results: In total, 26,623 patients were admitting to ward from our emergency department from August 2011 to July 2012, and 23,790 patients from August 2012 to July 2013. The rate of access block decreased from 55.29% to 50.01% ( p < 0.01) after holistic care unit was established. The mean time of ED length of stay was also improved from 18.04 hours to 15.43 hours ( p < 0.01). Conclusions: The newly established holistic care unit in our hospital improved the quality of medical care, not only physiologically but also psychologically.

Background: Multiple primary malignancies (MPM) have become increasingly prevalent worldwide. This investigation was aimed at establishing the clinicopathological characteristics of MPM patients and evaluating the impact of the living environment on MPM in the Taiwanese population. Materials and Methods: From January 2009 to December 2013, a total of 8,268 cancer patients were identified in our institutional center. Of these, 125 were diagnosed as MPM and thus enrolled. Data for clinicopathological features and treatment approaches for these MPM patients living in urban or suburb zone were obtained. Findings for the air pollution status in Taiwan were also collected. Results: The most common cancer match of MPM was esophageal cancer with hypopharyngeal cancer (12.8%), followed by colorectal cancer with gastric cancer (6.4%) and colorectal cancer with breast cancer (5.6%). The air quality was significantly worse in the urban than in the suburban zone and there was a remarkably higher portion of MPM patients in the urban zone suffering from grade III and IV post-chemotherapeutic neutropenia (30.8% vs 15.1%, P=0.036). Conclusions: The tumor frequency and site distribution should be taken into the clinical evaluation because there is a relatively high risk of developing MPM. This study also highlighted the potential influence of environmental factors on post-chemotherapeutic neutropenia for patients with MPM.

Background: Effects of the major ginsenoside Rg1 on mammalian longevity and physical vitality are rarely reported. Purpose: To examine longevity, tumor, and spontaneous locomotor activity in rats consuming Rg1. Methods: A total of 138 Wistar rats were randomized into 2 groups: control (N = 69) and Rg1 (N = 69). Rg1 (0.1 mg/kg per day) were orally supplemented from 6 months of age until natural death. Spontaneous mobility was measured by video-tracking together with body composition (dual energy x-ray absorptiometry) and inflammation markers at 5, 14, 21, and 28 months of age. Results: No significant differences in longevity (control: 706 days; Rg1: 651 days, p = 0.77) and tumor incidence (control: 19%; Rg1: 12%, p = 0.24) were observed between the two groups. Movement distance in the control group declined significantly by ~60% at 21 months of age, together with decreased TNF-α (p = 0.01) and increased IL-10 (p = 0.02). However, the movement distance in the Rg1 group was maintained ~50% above the control groups (p = 0.01) at 21 months of age with greater magnitudes of TNF-α decreases and IL-10 increases. Glucose, insulin, and body composition (bone, muscle and fat percentages) were similar for both groups during the entire observation period. Conclusion: The results of the study suggest a delay age-dependent decline in physical vitality during late life by lifelong Rg1 consumption. This improvement is associated with inflammatory modulation. Significant effects of Rg1 on longevity and tumorigenesis were not observed.

Since a large amount of waste polyester-cotton blended textiles can cause environmental pollution problems,it is crucial to develop sustainable technology for recycling textile wastes and producing valueaddedproducts. In this research, regenerated cellulose and polyester were obtained from thepolyester-cotton jean wastes by a sustainable process through the selective dissolving of cellulose fibersusing an ionic liquid (ILs), 1-butyl-3-methylimidazolium chloride ([Bmim]Cl). We developed an environmentallybenign decoloration approach without the bleaching or leaching processes. Instead, cellulose,polyester, and ILs were recycled from the selective degradation of indigo carmine (IC) or indigo dye inthe dye/ILs solution using the Bi11VO19 photocatalyst without impairing the dissolution capability ofILs. The selective decoloration of dye solution extracted from waste textiles involves interactions amongphotocatalysts, colorants, fibers, and media (ILs). The changes of dye and ILs molecules during the photocatalysisreaction were analyzed. FTIR and Raman spectra of the recycled ILs reveal that the chemicalstructure of ILs remains unchanged after the photocatalytic decoloration process. The ILs and photocatalystscan be recycled for repeated production of regenerated cellulose from waste jeans.

Background: The prevalence of esophageal cancer (EC) with second primary cancers (SPC) is increasing worldwide. This study was aimed to understand the clinical features of EC patients with SPC in the Taiwanese population. Materials and Methods: Clinical and laboratory data for 180 EC patients with or without SPC were collected between January 2009 and December 2013. Information on treatment approaches, location of SPCs and ABO blood type were also collected and stratified. Results: The most common SPC in EC patients was hypopharyngeal cancer, followed by laryngeal cancer and hepatocellular carcinoma in our study. Malignancies of colon, prostate and lung were also found. There was a significant higher portion of blood type A in the EC patients with SPC compared with those without (42.4% vs 19.5%, P=0.006). Conclusions: The frequency and SPC site distribution and blood type A should be considered in clinical evaluation of EC patients with a high risk of developing SPC in the Taiwanese population.

Tazarotene-Induced Gene 1 Enhanced Cervical Cell Autophagy through Transmembrane Protein 192

Shyu, Rong-Yaun,Wang, Chun-Hua,Wu, Chang-Chieh,Chen, Mao-Liang,Lee, Ming-Cheng,Wang, Lu-Kai,Jiang, Shun-Yuan,Tsai, Fu-Ming Korean Society for Molecular and Cellular Biology 2016 Molecules and cells Vol.39 No.12

Tazarotene-induced gene 1 (TIG1) is a retinoic acid-inducible protein that is considered a putative tumor suppressor. The expression of TIG1 is decreased in malignant prostate carcinoma or poorly differentiated colorectal adenocarcinoma, but TIG1 is present in benign or well-differentiated tumors. Ectopic TIG1 expression led to suppression of growth in cancer cells. However, the function of TIG1 in cell differentiation is still unknown. Using a yeast two-hybrid system, we found that transmembrane protein 192 (TMEM192) interacted with TIG1. We also found that both TIG1A and TIG1B isoforms interacted and co-localized with TMEM192 in HtTA cervical cancer cells. The expression of TIG1 induced the expression of autophagy-related proteins, including Beclin-1 and LC-3B. The silencing of TMEM192 reduced the TIG1-mediated upregulation of autophagic activity. Furthermore, silencing of either TIG1 or TMEM192 led to alleviation of the upregulation of autophagy induced by all-trans retinoic acid. Our results demonstrate that the expression of TIG1 leads to cell autophagy through TMEM192. Our study also suggests that TIG1 and TMEM192 play an important role in the all-trans retinoic acid-mediated upregulation of autophagic activity.

Der-Shiang Tsai,Mei-Hsuen Huang,Jen-Chieh Tsai,Yuan-Shuang Chang,Yung-Jia Chiu,Yen-Chang Lin,Lung-Yuan Wu,Wen-Huang Peng 한국식품영양과학회 2015 Journal of medicinal food Vol.18 No.5

In this study, we evaluated the analgesic and anti-inflammatory activities of a 70% ethanol extract from Rosa taiwanensis Nakai (RTEtOH). The analgesic effect was determined using acetic acid-induced writhing response and formalin test. The anti-inflammatory activity was evaluated by λ-carrageenan-induced paw edema in mice. The anti-inflammatory mechanism of RTEtOH was examined by measuring the levels of cyclooxygenase-2 (COX-2), nitric oxide (NO), tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6, and malondialdehyde (MDA) in the paw edema tissue and the activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), and glutathione reductase (GRd) in the liver tissue. The betulinic acid and oleanolic acid contents of RTEtOH were assayed by HPLC. The results showed that RTEtOH decreased the acetic acid-induced writhing responses (1.0 g/kg) and the late phase of the formalin-induced licking time (0.5 and 1.0 g/kg). In the anti-inflammatory models, RTEtOH (0.5 and 1.0 g/kg) reduced the paw edema at 3, 4, and 5 h after λ-carrageenan administration. Moreover, the anti-inflammatory mechanisms might be due to the decreased levels of COX-2, TNF-α, IL-1β, and IL-6, as well as the inhibition of NO and MDA levels through increasing the activities of SOD, GPx, and GRd. The contents of two active compounds, betulinic acid and oleanolic acid, were quantitatively determined. This study demonstrated the analgesic and anti-inflammatory activities of RTEtOH and provided evidence to support its therapeutic use in inflammatory diseases.

Tazarotene-Induced Gene 1 Interacts with DNAJC8 and Regulates Glycolysis in Cervical Cancer Cells

Chun-Hua Wang,Rong-Yaun Shyu,Chang-Chieh Wu,Mao-Liang Chen,Ming-Cheng Lee,Yi-Yin Lin,Lu-Kai Wang,Shun-Yuan Jiang,Fu-Ming Tsai 한국분자세포생물학회 2018 Molecules and cells Vol.41 No.6

The tazarotene-induced gene 1 (TIG1) protein is a retinoid-inducible growth regulator and is considered a tumor suppressor. Here, we show that DnaJ heat shock protein family member C8 (DNAJC8) is a TIG1 target that regulates glycolysis. Ectopic DNAJC8 expression induced the translocation of pyruvate kinase M2 (PKM2) into the nucleus, subsequently inducing glucose transporter 1 (GLUT1) expression to promote glucose uptake. Silencing either DNAJC8 or PKM2 alleviated the upregulation of GLUT1 expression and glucose uptake induced by ectopic DNAJC8 expression. TIG1 interacted with DNAJC8 in the cytosol, and this interaction completely blocked DNAJC8-mediated PKM2 translocation and inhibited glucose uptake. Furthermore, increased glycose uptake was observed in cells in which TIG1 was silenced. In conclusion, TIG1 acts as a pivotal repressor of DNAJC8 to enhance glucose uptake by partially regulating PKM2 translocation.
