Background/Aims: Real-world studies assessing the effectiveness and safety of sofosbuvir/velpatasvir (SOF/VEL) plus ribavirin (RBV) for Child-Pugh B/C hepatitis C virus (HCV)-related cirrhosis are limited. Methods: We included 107 patients with Child-Pugh B/C HCV-related cirrhosis receiving SOF/VEL plus RBV for 12 weeks in Taiwan. The sustained virologic response rates at off-treatment week 12 (SVR₁₂) for the evaluable population (EP), modified EP, and per-protocol population (PP) were assessed. The safety profiles were reported. Results: The SVR₁₂ rates in the EP, modified EP and PP were 89.7% (95% confidence interval [CI], 82.5-94.2%), 94.1% (95% CI, 87.8-97.3%), and 100% (95% CI, 96.2-100%). Number of patients who failed to achieve SVR₁₂ were attributed to virologic failures. The SVR₁₂ rates were comparable regardless of patient characteristics. One patient discontinued treatment because of adverse events (AEs). Twenty-four patients had serious AEs and six died, but none were related to SOF/VEL or RBV. Among the 96 patients achieving SVR₁₂, 84.4% and 64.6% had improved Child-Pugh and model for endstage liver disease (MELD) scores. Multivariate analysis revealed that a baseline MELD score ≥15 was associated with an improved MELD score of ≥3 (odds ratio, 4.13; 95% CI, 1.16-14.71; P=0.02). Patients with chronic kidney disease (CKD) stage 1 had more significant estimated glomerular filtration rate declines than patients with CKD stage 2 (-0.42 mL/min/1.73 ㎡/month; P=0.01) or stage 3 (-0.56 mL/min/1.73 ㎡/month; P<0.001). Conclusions: SOF/VEL plus RBV for 12 weeks is efficacious and well-tolerated for Child-Pugh B/C HCV-related cirrhosis. (Clin Mol Hepatol 2021;27:575-588)

Ching-Cheng Chao,Fang-Yuan Chen,Ching-Chiao Yang,Chien-Yu Chen 인하대학교 정석물류통상연구원 2016 JOURNAL OF INTERNATIONAL LOGISTICS AND TRADE Vol.14 No.1

The e-freight program launched by the International Air Transport Association (IATA) has gradually become a standard specification for international air freight operations. This study examined critical factors affecting air freight forwarders’ decision to adopt the IATA e-freight using a technology-organization-environment model with air freight forwarders in Taiwan as the base. Our findings show that ‘information technology (IT) competence’, ‘trading partner pressure’, ‘government policy’ and ‘competitive pressure’ all have significant positive effects on air freight forwarders’ decision to adopt the e-freight and the top three factors among these are ‘government funding’, ‘government’s active promotion’ and ‘government’s requirement of electronic air waybill (e-AWB)’. Finally, this study proposes strategies that can encourage air freight forwarders to decide on e-freight adoption for the information of relevant oK regyawniozradtison International Air Transport Association (IATA); IATA e-freight; Technology organization environment model; Air freight forwarder

Purpose: This study aimed to compare the ability of B-mode ultrasonography and magnetic resonance imaging (MRI) to predict the repairability of large-to-massive rotator cuff tears (RCTs). Methods: This cross-sectional study included participants with large-to-massive RCTs who underwent arthroscopic repair. B-mode ultrasonography and MRI were conducted prior to arthroscopic repair. B-mode ultrasonography was used to evaluate the echogenicity of the rotator cuff muscle using the Heckmatt scale. Intra-rater and inter-rater reliabilities were examined for two independent physicians. MRI was used to evaluate the degrees of tendon retraction, fatty infiltration of rotator cuff muscles, and muscle atrophy. Finally, two experienced orthopedic surgeons performed surgery and decided whether the torn stump could be completely repaired intraoperatively. Results: Fifty participants were included, and 32 complete repairs and 18 partial repairs were performed. B-mode ultrasonography showed good intra-rater reliability and inter-rater reliability for assessment of the muscle echogenicity of the supraspinatus and infraspinatus muscles. The correlation coefficients between B-mode ultrasound findings and MRI findings showed medium to large effect sizes (r=0.4-0.8). The Goutallier classification of the infraspinatus muscles was the MRI predictor with the best discriminative power for surgical reparability (area under the curve [AUC], 0.89; 95% confidence interval [CI], 0.81 to 0.98), while the Heckmatt scale for infraspinatus muscles was the most accurate ultrasound predictor (AUC, 0.85; 95% CI, 0.74 to 0.96). No significant differences in AUCs among the MRI and ultrasound predictors were found. Conclusion: B-mode ultrasonography was a reliable examination tool and had a similar ability to predict surgical reparability to that of MRI among patients with large-to-massive RCTs.

The Study of the Cycle Time Improvement by Work-In-Process Statistical Process Control Method for IC Foundry Manufacturing

Yu Cheng Lin,Chih Hung Tsai,Rong Kwei Li,Ching Piao Chen,Hsien Ching Chen 한국품질경영학회 2008 The Asian Journal on Quality Vol.9 No.3

The definition of cycle time is the time from the wafer start to the wafer output. It usually takes one or two months to get the product since customer decides to produce it. The cycle time is a critical factor for customer satisfaction because it represents the response time to the market. Long cycle time reflects the ineffective investment for the capital. The cycle time is very important for foundry because long cycle time will cause customer unsatisfied and the order loss. Consequently, all of the foundries put lots of human source in the cycle time improvement. Usually, we make decisions based on the experience in the cycle time management. We have no mechanism or theory for cycle time management. We do work-in-process (WIP) management based on turn rate and standard WIP (STD WIP) set by experiences. But the experience didn`t mean the optimal solution, when the situation changed, the cycle time or the standard WIP will also be changed. The experience will not always be applicable. If we only have the experience and no mechanism, management will not be work out. After interview several foundry fab managers, all of the fab can`t reflect the situation. That is, all of them will have an impact period after product mix or utilization varied. In this study, we want to develop a formula for standard WIP and use statistical process control (SPC) concept to set WIP upper/lower limit level. When WIP exceed the limit level, it will trigger action plans to compensate WIP Profile. If WIP Profile balances, we don`t need too much WIP. So WIP level could be reduced and cycle time also could be reduced.

( Ming-lung Yu ),( Ming-lun Yeh ),( Chi-yi Chen ),( Pin-nan Cheng ),( Ming-jong Bair ),( Jyh-jou Chen ),( Ching-chu Lo ),( Chi-ming Tai ),( Ching-yang Tsai ),( Kuo-chih Tseng ),( Chien-hung Chen ),( C 대한간학회 2020 춘·추계 학술대회 (KASL) Vol.2020 No.1

Aims: Insufficient data regarding the treatment strategy for partial response to nucleot(s)ide analogue (NUC) raised the aim of investigating tenofovir alafenamide (TAF) switching for chronic hepatitis B (CHB) patients with advanced fibrosis and partial response to other NUCs. Methods: CHB patients with advanced fibrosis (stage 3 or 4) and under NUC (except TAF) therapy with detectable hepatitis B virus (HBV) DNA for >52 weeks are enrolled to TAF 25 mg/day for 96 weeks. The objectives are viral suppression, alanine aminotransferase (ALT) normalization and safety. Results: From Feb. 2019, 34 patients, including 21 (61.8%) with entecavir, 10 (29.4%) TDF and 3 (8.8%) lamivudine or adefovir, were enrolled (15 [44.1%] male, median 53 years). The fibroscan demonstrated a mean of 10.5 kPa (7 [20.6%] cirrhotic). Sixteen (47.1%) patients were HBV e antigen positive, seven (20.6%) had YMDD mutation. The median HBV DNA level declined from 68.5 IU/mL at enrollment to 27.0 IU/mL at 4^th week, and undetectable at 12^th, 24^th, 36^th week, respectively, after TAF switching, with undetectable HBV DNA in 14/34 (41.2%), 17/33 (51.5%), 15/25 (60.0%), and 9/15 (60.0%) patients and rate of ALT normalization (≤40 U/L) of 85.3%, 85.3%, 84.8%, 92.0%, and 80.0%, respectively, after TAF switching. (figure 1) Two patients experienced transient virological breakthrough and another one developed at the final time follow up. Serum creatinine and eGFR levels were stable after TAF switching (figure 1). Two patients early terminated including one at 12^th week due to personal reason, and another one accidently died at 20^th week due to acute heart attack. Others suffered only mild degrees of adverse events which were considered unrelated to treatment. Conclusions: The preliminary results demonstrated the TAF switching is effective and safe in viral suppression for CHB patients with advanced fibrosis and partial virologic responses to other NUCs.

Slide Session : OS-CAD-06 ; Cardiology : Erythrocytosis Increased One-Year Mortality in Patients with St-Segment Elevation Myocardial Infarction Un-dergoing Primary Percutaneous Coronary Intervention

( Cheng Wei Liu ),( Yi Ching Lin ),( Chung Ming Tu ),( Pen Chih Liao ),( Kuan Change Chen ),( Yen Wen Wu ) 대한내과학회 2014 대한내과학회 추계학술대회 Vol.2014 No.1

Background: Anemia is associated with poor prognosis in patients with ST-segment elevation myocardial infarction(STEMI). However, it is unclear that erythrocytosis has protective effect in these populations. Hence, we conducted a retrospective cohort study to examine the relationship between erythrocytosis and mortality in patients with STEMI undergoing primary percutaneous coronary intervention (PCI ). Materials and Methods: We screened 1,156 consecutive patients with STEMI undergoing primary PCI in a single center during Feb 2007 and January 2012. There were 201 missing data for door-to-balloon time and 4 missing data for hemoglobin. Of 951 analyzable patients, they were divided into anemia (Hemoglobin<13.0mg/dl in men or <12.0mg/dl in women), normal hemoglobin, and erythrocytosis (hemoglobin =16.0mg/dl in men or =15.0mg/dl in women) groups. The study end point was one-year mortality. Results: There were 148, 535, and 268 patients in anemia, normal hemoglobin, and erythrocytosis groups, respectively. Patients in the anemia group were older and had lower body mass index than other two groups. There was more female, smokers, hypertension, and diabetes in the anemia group. One-year mortality rates were 16.2%, 6.5%, 2.6% (P<0.001) respectively. In univariate proportional hazards regression analysis, age, hemoglobin, total cholesterol, statin use, glycoprotein llb/llla inhibitor use, and TIMI risk score were associated with 1-year mortality in three groups. After adjustment for potential confounders, hemoglobin levels remained an independent predictor of one-year mortality in both anemia (hazard ratio 0.697, 95% CI 0.528-0.960) and erythrocytosis group (hazard ratio 3.129, 95% CI 1.1.474-6.642). Conclusions: Patients with STEMI and anemia had the worst outcomes than normal hemoglobin and erythrocytosis groups. Expectedly, hemoglobin had the protective effect on prognosis in anemia group. However, a hemoglobin level was an independent risk factor of one-year mortality in those with erythrocytosis.

Cis-3-O-p-hydroxycinnamoyl Ursolic Acid Induced ROS-Dependent p53-Mediated Mitochondrial Apoptosis in Oral Cancer Cells

Ching-Ying Wang,Chen-Sheng Lin,Chun-Hung Hua,Yu-Jen Jou,Chi-Ren Liao,Yuan-Shiun Chang,Lei Wan,Su-Hua Huang,Mann-Jen Hour,Cheng-Wen Lin 한국응용약물학회 2019 Biomolecules & Therapeutics(구 응용약물학회지) Vol.27 No.1

Cis-3-O-p-hydroxycinnamoyl ursolic acid (HCUA), a triterpenoid compound, was purified from Elaeagnus oldhamii Maxim. This traditional medicinal plant has been used for treating rheumatoid arthritis and lung disorders as well as for its anti-inflammation and anticancer activities. This study aimed to investigate the anti-proliferative and apoptotic-inducing activities of HCUA in oral cancer cells. HCUA exhibited anti-proliferative activity in oral cancer cell lines (Ca9-22 and SAS cells), but not in normal oral fibroblasts. The inhibitory concentration of HCUA that resulted in 50% viability was 24.0 μM and 17.8 μM for Ca9-22 and SAS cells, respectively. Moreover, HCUA increased the number of cells in the sub-G1 arrest phase and apoptosis in a concentrationdependent manner in both oral cancer cell lines, but not in normal oral fibroblasts. Importantly, HCUA induced p53-mediated transcriptional regulation of pro-apoptotic proteins (Bax, Bak, Bim, Noxa, and PUMA), which are associated with mitochondrial apoptosis in oral cancer cells via the loss of mitochondrial membrane potential. HCUA triggered the production of intracellular reactive oxygen species (ROS) that was ascertained to be involved in HCUA-induced apoptosis by the ROS inhibitors YCG063 and N-acetyl-L-cysteine. As a result, HCUA had potential antitumor activity to oral cancer cells through eliciting ROS-dependent and p53-mediated mitochondrial apoptosis. Overall, HCUA could be applicable for the development of anticancer agents against human oral cancer.

Investigation of Goats' Milk Adulteration with Cows' Milk by PCR

Cheng, Yeong-Hsiang,Chen, Su-Der,Weng, Ching-Feng Asian Australasian Association of Animal Productio 2006 Animal Bioscience Vol.19 No.10

Goats' milk adulteration with cows' milk is becoming a big problem. In the past, the urea-polyacrylamide gel electrophoresis assay with different motility of ${\alpha}S1$-casein has been applied for the identification of cows' milk adulteration. The detection sensitivity is 1.0%. The aim of this study was to develop a faster and more sensitive method to detect cows' milk which may be present in adulterated goats' milk and goats' milk powder. The published primer was targeted at highly conserved regions in bovine mitochondrial DNA (a 271 bp amplicon). This amplicon was cloned and sequenced to further confirm bovine specific sequence. The chelex-100 was used to separate bovine somatic cells from goats' milk or goats' milk powder samples. Random sampling of different brands of goats' milk powder and tablets from various regions of Taiwan showed the adulterated rate was 20 out of 80 (25%) in goats' milk powders and 12 out of 24 (50%) in goats' milk tablets. With this system, as low as 0.1% cows' milk or cows' milk powder in goat milk or goat milk powder could be identified. This chelex DNA isolation approach provides a fast, highly reproducible and sensitive method for detecting the adulteration of goats' milk products.

Statin Therapy for Primary Prevention of Atrial Fibrillation: Guided by CHADS 2 /CHA 2 DS 2 VASc Score

Chen-Ying Hung,Yu-Cheng Hsieh,Jin-Long Huang,Ching-Heng Lin,Tsu-Juey Wu 대한심장학회 2014 Korean Circulation Journal Vol.44 No.4

Atrial fibrillation (AF) is the most common arrhythmia and is associated with increased cardiovascular morbidity and mortality. The anti-arrhythmic effect of statins on AF prevention appears to be highly significant in most clinical studies. However, some discrepancies do existamong different clinical studies. Different clinical settings and types of stains used may explain these differences between trials. The CHADS 2and CHA 2 DS 2 VASc scoring systems have been used for stroke risk stratification in AF patients. The recent study suggested that thesescores can also be used to guide statin therapy for AF prevention. Patients with higher scores had a higher risk of developing AF and gained morebenefits from statins therapy than those with lower scores. This review article focused on the ability of these scores to predict AF preventionby statins.
