根據檢測結果發現,定性測試合格率為100%,而定量測試合格率為34.6% (18/52)。其中定量測試不合格的原因以每小時換氣次數未達8ACH以上者佔59.6% (31/52),壓差值未達8Pa以上者則佔13.4% (7/52)。針對定量測試每小時換氣次數未達8ACH以上者,可同時增加病房進排氣量,以達到8ACH以上並維持壓差值達到8Pa以上的要求;此外亦可藉減少病房體積以提升每小時換氣次數至≧8ACH來進行改善。如果每小時換氣次數已達到8ACH以上的要求,但壓差值未達8Pa以上者,則先確認病房氣密性後,利用調整門縫開口大小或增加排氣量,以符合壓差值要求。
There are 52 negative pressured isolation rooms (NPIRs) in four different hospitals were assessed by both qualitative and quantitative testing, to evaluate the performance during operation. To improve the operating performance and effectiveness, feasible solution was then proposed based on “Negative pressured isolation room reference manual of CDC and IOSH (NPIRRM)” in Taiwan. Field study of performance and effectiveness in NPIRs were divided into qualitative and quantitative testing. The smoke tube was used for the observation of airflow pattern in qualitative testing. In quantitative testing, anemometer was utilized to measure air velocity as well as intake or exhaust air volume if the opening area is available. The air-change rate (ACH) was then obtained by intake air volume and room volume. Finally, the micromanometer was used to measure pressure differential of NPIRs.
The results of qualitative analysis in 52 NPIRs indicate that all airflow directions were correct. The measurements of air-change rate (ACH) less than 8ACH are approximate to 59.6% (31/52). The pressure differential of studied NPIRs was less than 8Pa which suggested in the NPIRRM of Taiwan about 13.4% (7/52). Therefore, based on criteria of 8ACH and 8Pa in quantitative testing, only 34.6% (18/52) meet the requirements indicated in NPIRRM of Taiwan. For those NPIRs with air-change rate less than 8ACH, increasing intake and exhaust air volume at the same time was suggested to improve air change rate and maintain the pressure differential. In addition, downgrade of the room volume is also a possible way to meet the requirements. NPIRs with pressure differential smaller than 8Pa, which air-tightness should be confirmed, and then decreasing doorway and increasing exhaust air volume are adjusted to meet the above requirements

Bacteriocins are proteinaceous toxins produced by bacteria to kill or inhibit the growth of other bacterial strains. They are considered having potential in the application of the food industry. We screened the antibacterial activity of six lactic acid bacteria strains from the marine environment (such as a variety of shellfish: clams, oysters, fish and shrimp gut, etc.) and our culture collections (250 strains). The results showed that the bacteriocins produced by strain A and B have significant antimicrobial activity and inhibit aquatic pathogen of Vibrio alginolyticus and Vibrio parahaemolyticus strains.Therefore, we chose strain A and B as the screening of this study. Based on biochemical tests and 16S rDNA sequence analysis, the preliminary identification of strains A and B belong to L. plantarum. Agar well diffusion antibacterial results show that the crude extracts with ammonium sulfate precipitation of strain A after 48 hours fermentation effectively inhibit Vibrio alginolyticus, and that after 72 hours fermentations to inhibit Vibrio parahaemolyticus. In strain B, the crude extracts with ammonium sulfate precipitation of 60 hours fermentation effectively inhibit Vibrio alginolyticus, and that of 48 hours fermentations to inhibit Vibrio parahaemolyticus. Further, the antibacterial activity measured by the crude extract of strain A fermentation after FPLC gel filtration separation. The results showed that the bacteriocin produced by strain A has an inhibitory effect of Vibrio alginolyticus, should be considered to have considerable potential for inhibiting aquatic pathogens on aquaculture applications

在台灣,我們研發團隊首先從台灣老烏龍茶葉中成功將「金花菌」分離篩選純化出來,經「食品工業研究所」菌種鑑定證實為「金花菌」,已成功開發低單寧酸、咖啡因及茶鹼並結合『台灣味的金花菌茶』之保健茶葉。
本研究中,我們進一步探討來自Eurotium cristatum、Penicillium citrinum及Fusarium solani之單寧酶特性。在單寧酶平板篩選試驗中,三者均有降解單寧之能力,但不同的菌株所降解的區域大小則不同,其中,以Eurotium cristatum生長的速率最慢,這可能與單寧酶之產量有關。
將Eurotium cristatum、Penicillium citrinum及Fusarium solani分別培養在添加2 %單寧酸的MSM中所收取之培養液進行單寧酶活性圖譜分析,結果顯示Penicillium citrinum及Fusarium solani有band出現,具單寧酶活性,Eurotium cristatum則無活性;若對照單寧酶活性定量分析實驗,則發現Penicillium citrinum及Fusarium solani粗樣本單寧酶活性高於Eurotium cristatum的粗樣本(七倍以上),這可能是Eurotium cristatum在單寧酶圖譜活性定性實驗均無法顯現活性的原因;若將Eurotium cristatum、Penicillium citrinum及Fusarium solani分別培養在添加0.5 %單寧酸的MSM中所收取之培養液進行單寧酶活性圖譜分析,則全部無法顯現單寧酶活性,將各樣本進行單寧酶活性定量分析實驗後,發現培養於添加0.5 %單寧酸培養基樣本活性明顯較低。另外,單寧酶圖譜定性活性分析實驗中顯示,SDS與beta-mercaptoethanol會使Penicillium citrinum及Fusarium solani所生產之單寧酶失去活性。
未來將先進行單寧酶之純化,再利用LC/MS/MS及PCR方法選殖單寧酶cDNA,分析這些單寧酶胺基酸序列是否具有活性位置的高度保留序列,並將單寧酶的 cDNA序列轉殖至細菌或真菌之蛋白質表現系統,期望能夠透過這些表現系統產出大量具有活性之重組單寧酶。
Tea contains tannic acid, caffeine and theophylline ensure the body would be a negative impact, and is often ignored. Many scientific literature reports have also confirmed that the use of biotechnology can reduce the tannic acid, caffeine and theophylline in tea. “Eurotium cristatum”is the treasure in Pu-erh tea and Fuzhuan Brick tea in China. It can make tea color more beautiful, softer texture, and sweeter. Eurotium cristatum on hypolipidemic, weight-loss, reduction of three-high and inhibition of cancer cells effects have been published in many leading academic journals and medical clinical reports.
We first successfully isolated Eurotium cristatum from Taiwan Oolong tea and confirmed as the " Eurotium cristatum " by the strain identification from “Institute of Food Industry” in Taiwan. We have successfully developed low tannic acid, coffee and theophylline combined with an " Eurotium cristatum containing Taiwan health tea ".
In this study, we further investigated the characteristics of tannases from Eurotium cristatum, Penicillium citrinum and Fusarium solani. The results of tannin plate assay suggest that three of them all have ability in tannin-degradation and the zone sizes are different in different fungi. However, the growing rate of Eurotium cristatum was the most slowest. This is probably relative to production level of tannase.
We collected the secreted supernatant from the culture of Eurotium cristatum, Penicillium citrinum and Fusarium solani in MSM contain 2 % tannic acid and analyzed them by zymogram assay. The results showed that Penicillium citrinum and Fusarium solani have bands appeared with tannase activity but Eurotium cristatum revealed no activity. When compare the tannase activity from all crude samples analyzed between qualitative and quantitative assays, we found that the tannase activity from Penicillium citrinum or Fusarium solani is higher than Eurotium cristatum five times more by quantitative assay. It could be the reason why we can’t see any band appeared in all Eurotium cristatum zymogram assay. However, if we collected the secreted supernatant from the culture of Eurotium cristatum, Penicillium citrinum and Fusarium solani in MSM contain 0.5 % tannic acid and analyzed them by zymogram assay. They all showed no any bands appeared with tannase activity. All data demonstrated that crude samples from 0.5% tannic acid are lower than 2% tannic acid. Furthermore, we performed the addition of SDS or beta-mercaptoethanol in zymogram assay, they showed that the tannase activity was all abolished from Penicillium citrinum and Fusarium solani.
In the future, we will purify the tannase and further clone tannase cDNA by LC/MS/MS and PCR strategies. Then, we will try to align the amino acid sequences and found the conserve active site. We hope to construct the expression vectors in bacterial or fungi system and express large amount of recombinant tannase with high activity

Prostate cancer is the most common cancer affecting men in Western countries. In Taiwan, it is the 5th common cancer in men and increasing incidence. Epigallocatechin-3-gallate (EGCG) represents the major Green Tea Polyphenol constituents, the most popular beverage next to water that has potential to be developed as a chemo preventive agent for prostate cancer. The effects of anti-prostate cancer by EGCG were never been systemic evaluated. The purpose of this study is to verify the inhibitory effect on prostate carcinogenicity including modulation of signal transduction of apoptosis by western blots and shift of cell cycle by FACscan flow cytometry. The mechanisms of anti prostate carcinogenesis, evaluation models will be established on EGCG. The results indicated that EGCG significantly induced the apoptosis protein levels of caspase3/7/8/9, parp and Cyt-C and JNK. In addition, and reduced the inhibitory protein levels of BCL-2. The apoptosis expression was significantly higher treated by EGCG than control. The results from these investigations will prove to be helpful for understanding the anti-prostate cancer mechanics by EGCG and provide novel insights in developing of chemopreventive agents in clinical medicines

背景:
在一般人群中很常見的情感性疾患,主要是重度憂鬱症(MDD)和雙極性情感性障礙疾病(BPD躁鬱症,包括BP I第一型躁鬱症和BP II第二型躁鬱症)。然而,很少有人知道情感性疾患和基因之間的臨床特徵。本研究目的是探討情感性疾患與相互關聯的MTERFD3基因單一核苷酸多型性之間的臨床特徵。
材料與方法:
這項研究中有1242位參加者,464位個案,522位家屬和256位健康控制組,2008年至2012年在台灣南部及北部共六個臨床單位收案,包括診所、區域醫院或醫學中心。參加者接受訓練過的研究助理,採用複合性國際診斷訪談問卷(CIDI),收集人口學和臨床特徵的資料。資料的收集來自重度憂鬱或躁鬱症患者,以及他們的家屬和其他無血緣健康成員。我們探討MTERFD3基因單一核苷酸多型性與臨床特徵間的相關性研究,也轉殖MTERFD3基因的啟動子,觀察單一核苷酸多型性對啟動子活性的影響。
結果:
使用PSQI匹茲堡睡眠品質量表,評估在過去的一個月受試者的睡眠情況,在個案與家屬和控制組間有顯著差異。該項目含睡眠品質 (p<0.001)、潛伏期 (P <0.001)、效率 (P <0.001)、睡眠困擾(P <0.001)、使用安眠藥 (P <0.001) 和白天功能 (P <0.001)。但是與睡眠時間沒有顯著差異(P =0.274)。接下來分別分析量表總分和七項指標在不同基因型間與診斷之間的關係,分別比較三基因型(CC、CG、GG)或合併C基因型(CC/CG、GG)或G基因型(CC、CG/GG)進行兩組比較。整體言之,不同診斷之間常有顯著性差異,除品質指標在CC/CG與GG比較時兩因子有交互作用外,其餘皆無交互作用。而單一核苷酸多型性不同基因型對自殺、焦慮與憂鬱的發生也沒有影響。為進一步分析該單一核苷酸多型性是否對特定族群的影響較大,分別探討CC、CG、GG三基因型或合併CC/CG型與GG型比較或合併CG/GG型與CC型比較,以及將病人組和健康組合併單獨進行比對分析,結果發現自殺、焦慮、憂鬱與躁症和該單一核苷酸多型性均沒有顯著相關。但在探討單一核苷酸多型性對基因啟動子活性的影響上,我們發現rs2287161單一核苷酸多型性會影響MTERFD3啟動子活性,G較C的啟動子活性為高。
結論:
從這個研究結果可以為我們提供更多的診斷資訊和醫療資源利用,做為未來預防精神疾病發展的參考。
Abstract
Backgrounds:
Affective disorders, mainly depressive (MDD) and bipolar disorders (BPD, including BP I and BP II), are common in the general population. However, little is known between genes and their clinical features. The aim of this study is to correlate SNP rs2287161 of MTERFD3 gene with clinical features.
Materials and Methods:
There were 1242 participants in this study, including 464 probands, 522 relatives and 256 controls from six clinics, regional hospitals or medical centers in the southern and northern Taiwan from 2008 to 2012. Participants were interviewed by well-trained interviewers using Composite International Diagnostic Interview (CIDI) to collect data on demographic and clinical features. The data were collected from patients with depression or bipolar disorder, their families and other normal people. We also cloned the promoters with different SNPs of MTERFD3 gene to study the correlation of SNPs and clinical features. The promoter activities were measured by Dual luciferase assay system and in a luminometer.
Results:
The Pittburgh Sleep Quality Index was used to assess the sleep situation of subjects in the past month. There were significant differences among probands, relatives and controls. The items are quality (p<0.001), latency (p<0.001), efficiency (p<0.001), disturbances (p<0.001), use of medications (p<0.001) and day-life dysfunction (p<0.001). However, there was no significant difference in sleep duration (p=0.274). To study the interaction of diagnoses (BPI and II) and the SNP rs2287161 of MTERFD3 in PSQI, we didvided the all cases into three genotype groups (CC, CG and GG) or two groups (CC/CG, GG or CG/GG, CC). In general, the scores of PSQI are signicantly different in disgnosis. Except for quality in comparison of groups CC/CG and GG, there are no interactions of diagnosis and this SNP of MTERFD3in other items. We also correlated the different behaviors, such as suicide, anxiety and depression, with this SNP of MTERFD3 and found that this SNP is not associated with these behaviors. To further study the correlation of behaviors and this SNP, we analyzed the data of controls and patients individually and found that this SNP is not associated with these behaviors. To understand if this SNP inloves in MTERFD3gene expression, we cloned the promoter fragments with different alleles on this SNP and found that G allele exerts higher promoter activity than C.
Conclusion:
The results from this study may provide us more information for development of diagnosis and medical resource utilization for preventing mental diseases in the future

messenger RNA 的表現。為了進一步探求 chalcone 抑制 T24 細胞侵入的機轉,利用西方墨點法,我們發現訊息傳遞途徑中的FAK、ERK1/2、p38、JNK1/2 和 Akt 的磷酸化表現皆會受到 chalcone 所抑制。然而這些蛋白的活化是否調控著 T24 細胞的侵襲能力,透過專一性抑制劑:U0126、SB203580、SP600125 及 LY294002 幫助我們釐清了 ERK1/2、p38、JNK1/2 及 PI3K 路
徑可以調控 T24 細胞 MMP-2、MMP-9 及u-PA 的表現。另外在實驗中也證實 small GTPase family,如:Ras、Rac-1、Cdc42、RhoA、RhoB 的蛋白表現量也會受到 chalcone 所抑制。此外,核蛋白中 NF-κB、c-Fos、c-Jun 的表現皆會受到 chalcone 所抑制。綜合上述所有的實驗結果,chalcone 可能是透過FAK/MAPK 和 FAK/PI3K/Akt signal pathway 來影響下游的轉錄因子
NF-κB 的活性,進而影響分泌 MMP-2 、 MMP-9 及 u-PA,最後抑制 T24 細胞的侵襲及移動。
Chalcone is a flavonoid antioxidant extracted from Angelica keiskei koidzumi. It has various effect such as antibacterial and anti-inflammatory activities. In recent studies, chalcone has shown its anti-cancer property. The purpose of this study is to investigate the inhibitory effect and mechanism of
chalcone on human bladder cancer cells metastasis in vitro. We chosed a highly metastastic human bladder T24 cancer cell line which was treated with various concentrations of chalcone to investigate the potential of inhibiting cancer cell migration and invasion. First, we found that chalcone inhibited T24 cells migration and invasion via wound healing assay and Boyden chamber assay. MMP-2, MMP-9, u-PA activity and messenger RNA level were also inhibited by chalcone via gelatin zymography, casein-plasminogen zymography and polymerase chain reaction. In the signal transduction pathway, we found that the phosphorylation of the FAK, ERK1/2, p38, JNK1/2 and Akt were inhibited by chalcone via Western blotting. To verify the activation of above proteins whether regulated T24 metastatic ability, we used specific inhibitors:U0126, SB203580, SP600125 and LY294002 to clarified that the signal transduction of FAK, ERK1/2, p38, JNK1/2 and PI3K/Akt regulated MMP-2 , MMP-9 and u-PA expression. On the other hand, chalcone inhibited the protein level of Ras, Rac-1, Cdc42, RhoA and RhoB with concurrent reduction in the expression level of NF-κB, c-Fos and c-Jun. In the present study, we demonstrated that chalcone inhibited T24 cells might be through the FAK/MAPK and FAK/PI3K/Akt signal pathways and exerted inhibitory effect on the expression of NF-κB transcription factor, MMP-2, MMP-9 and u-PA, afterward inhibited migration and invasion in T24 human bladder cancer cell. This study suggests a possible role of chalcone in bladder cancer therapy

Increase with age, testicular function, such as the manufacture of sperm and hormonal effects reduce the increase in its causes and testicular oxidative damage. Contain high levels of selenium in the testis, many studies have shown that selenium anti-inflammatory, anti-tumor effects, its mechanism of action and antioxidant capacity. The purpose of this study was to investigate the two forms of selenium supplement on aging mice testis oxidation state and proteomics. 64 weeks of BALB / c male mice were randomly divided into three groups according to body weight, and were fed to experience feed: control group (OC), inorganic selenium group (SE; 0.5 mg/kg diet), and organic selenium group (SY; 0.5 mg/kg diet). We use 6-week-old young rats, as the young control group (YC). Seven weeks after feeding, analysis of testicular tissue fluid homogenate antioxidant enzyme activity was found in the oxidative stress of the OC group which was significantly higher than the YC group; therefore, we found that selenium supplementation can improve the increased oxidative stress. In the testis protein changes of two-dimensional gel electrophoresis, we found seven protein spots for the OC group was notably higher than the YC group, and the SE group with SY group was obviously lower than the OC group identified by identification by mass spectrometry identity of their protein, which contains 78 kDa glucose-regulated protein (GRP78). These proteins are associated with aging; through selenium supplementation they can reduce the increase due to aging. Then we analyze 78 kDa glucose-regulated protein (GRP78) with western blot for further and discover that the expression of GRP78 in the OC group testicles is lower than the YC group, while the complement of different types of selenium, the performance showed a significant increase. Additionally, we adopt 79-week-old SD male rats randomly divided into five groups according to body weight, fed with experience feed: control group (OC), inorganic selenium group (LSE; 0.5 mg/kg diet、HSE; 2 mg/kg diet), and organic selenium group (LSY; 0.5 mg/kg diet、HSY; 2 mg/kg diet). At the other side, 14-week-old young rats, as the young control group (YC). Twelve weeks after feeding, analysis of testicular tissue fluid homogenate antioxidant enzyme activity was found in the oxidative stress, western blot analysis of GRP78 expression in the testes. The γ-GTP activity was measured; we found the rats of the results compared to the results of the analysis of the mouse testis, their tendencies are the same. This study shows that, given selenium supplements can improve the antioxidant capacity of the testes of aging, and affect the performance of testicular protein. This result can be used as the reference to prevent the degradation of testicular function

第八章 參考文獻 53[[abstract]]背景:在糖尿病腎病變造成的纖維化中,高血糖是一個重要的危險因子。先前的研究發現,IL-7具有抗肺纖維化的潛力。然而,IL-7在腎纖維化的過程扮演的角色未知。因此,我們想探討IL-7在腎近端小管上皮細胞高糖的環境下所扮演的角色。方法:細胞培養在高糖最終濃度為27.5 mM兩天,在最後24小時加入不同濃度的IL-7 (10、 50、100與 200 ng/ml)。利用ELISA來偵測細胞外分泌的纖維蛋白及乙型生長轉型因子濃度。再使用Western blot來觀察EMT的標記【包括α-smooth muscle actin ( α-SMA) 及 E-cadherin】,訊息傳遞,及EMT的啟動子( Snail, Slug )之表現。以及使用免疫螢光染色來觀察原位蛋白的表現(譬如Fibronectin, α-SMA, E-cadherin, Snail, Slug)。結果:我們發現IL-7抑制高糖誘導減少的細胞生長及抑制高糖誘導的細胞纖維化。並且IL-7能夠阻斷高糖誘導所升高的纖維蛋白,第一型乙型轉型生長因子,第一型乙型轉型生長因子接受器以及磷酸化Smad2/3。相反的,IL-7可以逆轉高糖所誘導減少的Smad7。除此之外,IL-7能夠抑制高糖所誘導增加的α-SMA, Snail及Slug,並且能逆轉高糖誘導減少的E-cadherin。結論:IL-7抑制高糖誘導的腎近端小管纖維化可能通過調節 Smads和EMT的途徑。
Background: Hyperglycemia is the most important risk factor in the progression of renal fibrosis in diabetic kidney. Based on previous studies, interleukin-7 (IL-7) may possess antifibrotic activities in pulmonary fibrosis model. However, the role of IL-7 in the pathogenesis of renal tubulointerstitial fibrosis remains unclear. Thus, we hereby elucidate the effects of IL-7 in cultured renal proximal tubular epithelial cells (designated as HK-2) treated under hyperglycemic media. Material and Methods: Cells were cultured in high glucose (HG, 27.5mM) for 2 days. Different concentration of IL-7 (10、 50、100 or 200ng/ml) was added in the last 24 hours of culture. ELISA was used to evaluate the secreted protein such as fibronectin and TGF-β1. Western blot was used to examine the EMT marker (including α-smooth muscle actin (α-SMA) and E-cadherin), signal transducer (including Smad Smad2/3 and Smad7) and EMT initiator (e.q Snail, Slug). Immunofluorescence staining was used to assay the in situ expression of proteins (e.q. α-SMA, E-cadherin and Snail). Results: We found that IL-7 significantly attenuated HG-inhibited cellular growth and HG-induced fibrosis. HG-induced up-regulation of fibronectin, TGF-β, TGF-β RII and p-smad2/3 was markedly inhibited by IL-7. On the contrary, HG-induced down-regulation of smad7 was significantly reversed by IL-7 instead. Moreover, IL-7 markedly inhibited HG-induced increase in α-smooth muscle actin and snail. Whereas HG-induced decrease in E-cadherin expression was reversed as well. Conclusion, IL-7 has the potential to inhibit high glucose-induced renal tubular fibrosis possibly by modulating Smads and EMT pathway
