A field survey was conducted to investigate the presence of Borrelia burgdorferi sensu lato (s.l.) in six counties of Taiwan. Spirochetes were successfully isolated from one rodent ear sample out of 485 rodent ears and 53live, fed tick (Ixodes granulatus) samples. The spirochetes were confirmed to be B. burgdorferi s.l. by real-time PCR. In addition, 23 of 113 tick samples were tested positive for Borrelia DNA according to real-time PCR. The Borrelia isolate from the rodent and the 23 Borrelia DNA samples from the ticks were identified as B. valaisiana-related genospecies by phylogenetic analysis based on flagellin gene sequences. These findings suggest that the Borrelia valaisiana-related strains are maintained in a zoonotic cycle between tick vectors and reservoir hosts in Taiwan.

Endemic species of oceanic islands are vulnerable due to their geographical isolation and small population sizes. For endangered island species, captive breeding program is an important strategy for conservation and sustainable management. Pachyrhynchus sarcitis is a flightless weevil decorated with colourful markings and distributed exclusively on several islets of Southeast Asia including Lanyu, Ludao, and Babuyan Islands. The life history of threatened Pachyrhynchus species of these islands was poorly known. This study reared P. sarcitis from Lanyu and Babuyan Islands for the first time in the laboratory using their host plant (Leea guineensis). The two island populations showed significant differences in instar numbers, in which the weevils from Lanyu Island had a higher instar number regardless the length of developmental duration. The adult body size of both sexes of the Babuyan population became smaller under laboratory condition; whereas Lanyu population in the laboratory did not show this trend. The differences in larval development might suggest local adaptation to the host plants or other life history associated characteristics which requires further research.

從東亞儒學視域論鄭齊斗對孟子「知言養氣」說的解釋

黃俊傑(Huang Chun-chieh) 한국양명학회 2005 陽明學 Vol.- No.13

18세기 조선의 양명학자인 정제두는 유교경전에 대한 다양한 견해를 피력하였는데, 『맹자』「공손추상」 2장에 나타나 있는 맹자의 ‘지언양기’(知言養氣)설에 대해서도 나름대로의 식견을 나타내 보이고 있다. 본 논문에서는 맹자의 ‘지언양기’설에 대한 정제두의 해설을 분석하고, 이를 동아시아 유학사의 시각에서 조명해보고자 한다. 이를 위해 맹자의 사상에 대한 정제두의 분석을 먼저 살펴보고, 주희나 왕양명 등과의 비교를 통해 동아시아 사상사적 맥락 안에서의 정제두의 위치를 탐구해보고자 한다. 특히 그는 ‘마음으로써 말을 결정한다’ 혹은 ‘사람의 말은 모두 마 음으로부터 나온다’는 점을 강조하고, 또한 ‘마음을 가지고 기(氣)를 결정 한다’고 주장하였는데, 이러한 이해는 주자의 해석보다는 왕양명의 해석에 가까운 것으로 볼 수 있으며, 이는 곧 양명학적 맥락 안에서의 정제두의 사상의 특성을 보여주는 것이라 할 수 있다.

Hericium erinaceus Mycelium and Its Isolated Compound, Erinacine A, Ameliorate High-Fat High-Sucrose Diet-Induced Metabolic Dysfunction and Spatial Learning Deficits in Aging Mice

Aging and lifestyle factors, including high-sugar and high-fat diets, promote a systemic metabolic imbalance that promotes neurodegeneration. Hericium erinaceus has long been used in traditional Chinese medicine. Recently, its functional activities, such as antimetabolic dysfunction, antineuroinflammatory activities, and stimulation of nerve growth factor (NGF) synthesis, have been revealed. This study demonstrated that Hericium erinaceus mycelium (HEM) and an isolated diterpenoid derivative, erinacine A (EA), may reverse spatial learning disabilities in aging mice (15 months old) fed with a high-fat and high-sucrose diet (HFSD). Aging mice were randomly assigned to one of four treatment groups: (1) a chow diet (control), (2) an HFSD, and an HFSD supplemented with either (3) HEM or (4) EA for 18 weeks. The Morris water maze (MWM) and Y-maze were used for behavioral assessments. Both HEM- and EA-treated mice had shorter mean daily escape latencies than HFSD-treated mice in the MWM. In addition, HEM-treated mice had a slightly increased exploratory time and frequency in the novel arm in the Y-maze. Quantitative PCR revealed that both HEM- and EA-treated mice exhibited reduced messenger RNA (mRNA) expression of tumor necrosis factor-α, interleukin-1β, and HEM-treated mice exhibited increased mRNA expression of NGF and NeuN in the hippocampus. Moreover, HEM and EA also decreased body weight, abdominal fat, plasma glucose, serum and liver total cholesterol, and liver triacylglycerol. Thus, HEM may be a potential health-promoting supplement for minimizing the progression of aging and obesity-induced neurodegeneration by reducing metabolic abnormalities and neuroinflammatory cytokines and increasing neurogenesis factors.

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.

Effect of a Carbon Additive on the TbCu7-type Melt-spun Sm(Co, M)7 (M=Ti, Zr, Hf, V and Ge) Ribbons

Chih-Chieh Hsieh,Shih-Teng Huang,Jin-Sheng Guo,Chih-Wei Shih,Wen-Cheng Chang,Huang-Wei Chang,Chun-Chung Shaw 한국물리학회 2013 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.63 No.3

The effect of a carbon additive on the microstructure and the magnetic properties of melt-spunSmCo7−xMxCy (M=Ti, Zr, Hf, V and Ge; x = 0 - 0.3 and y = 0 - 0.1) ribbons was studied. Based on the XRD and the TEM analyses, a pure 1:7 phase could be formed for the C-containingribbons with M= Ti and Ge. However, carbide phases, i.e., Sm2C3 for M=Zr and Hf, and SmCoC2for M=V, respectively, were found. Nevertheless, a slight C addition may effectively refine themicrostructure and improve both the intrinsic coercvity and the magnetic energy product in all thestudied ribbons. Among them, the SmCo6.9V0.1C0.1 ribbons with r = 58.7 emu/g, iHc = 13.5kOe and (BH)max = 9.3 MGOe, and the SmCo6.9Hf0.1C0.1 ribbons with r = 61.6 emu/g, iHc =11.8 kOe and (BH)max = 10.3 MGOe are most suitable for the bonded magnet applications.

Objective: Choice of hysterectomy and adjuvant treatment for International Federation of Gynecology and Obstetrics (FIGO) 2009 stage II endometrioid endometrial cancer (EEC) is still controversial. Aims of this study were to evaluate survival benefits and adverse effects of different hysterectomies with or without adjuvant radiotherapy (RT), and to identify prognostic factors. Methods: The patients at 14 member hospitals of the Taiwanese Gynecologic Oncology Group from 1992 to 2013 were retrospectively investigated. Patients were divided into simple hysterectomy (SH) alone, SH with RT, radical hysterectomy (RH) alone, and RH with RT groups. Endpoints were recurrence-free survival (RFS), overall survival (OS), disease-specific survival (DSS), adverse effects and prognostic factors for survival. Results: Total of 246 patients were enrolled. The 5-year RFS, OS, DSS and recurrence rates for the entire cohort were 89.5%, 94.3%, 96.2% and 10.2%, respectively. Patients receiving RH had more adverse effects including blood loss (p<0.001), recurrent urinary tract infections (p=0.013), and leg lymphedema (p=0.038). Age over 50-year (HR=9.2; 95% confidence interval [CI], 1.2–70.9) and grade 3 histology (HR=7.28; 95% CI, 1.45–36.6) were independent predictors of OS. Grade 3 histology was an independent predictor of RFS (HR=5.13; 95% CI, 1.38–19.1) and DSS (HR=5.97; 95% CI, 1.06–58.7). Patients receiving adjuvant RT had lower locoregional recurrence (p=0.046), but no impact on survival. Conclusion: Different treatment modalities yield similar survival outcomes. Patients receiving SH with RT had lower locoregional recurrent with acceptable morbidity. Age and tumor grading remained significant predictors for survival among patients with FIGO 2009 stage II EEC.

( Meng Chieh Wu ),( Hsin Kai Huang ),( Chun Cheng Zhang ),( Li Sheng Chang ),( Yung Ze Cheng ),( Chien Chin Hsu ),( Kao Chang Lin ) 대한내과학회 2014 대한내과학회 추계학술대회 Vol.2014 No.1

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.

Purpose The aim of this study was to investigate the efficacy of various epidermal growth factor receptor (EGFR)–tyrosine kinase inhibitors (TKIs) plus bevacizumab in advanced EGFR-mutant lung adenocarcinoma patients. Materials and Methods From August 2016 to October 2020, we enrolled advanced lung adenocarcinoma patients harboring exon 19 deletion or L858R receiving gefitinib, erlotinib and afatinib plus bevacizumab as the first-line treatment for the purposes of analysis. Results A total of 36 patients were included in the final analysis. Three patients received gefitinib, 17 received erlotinib, and 16 received afatinib combined with bevacizumab as the first-line treatment. The objective response rate was 77.8%, and disease control rate was 94.4%. The overall median progression-free survival (PFS) was 16.4 months, while the median PFS was 17.1 months in patients with exon 19 deletion, and 16.2 months in patients with L858R mutation (p=0.311). Regarding the use of different EGFR-TKIs, the median PFS was 17.1 months in the erlotinib group and 21.6 months in the afatinib group (p=0.617). In patients with brain metastasis at baseline, the median PFS was 18.9 months in the erlotinib group and 16.4 months in the afatinib group (p=0.747). Amongst patients harboring exon 19 deletion, the median PFS was 16.2 months in the erlotinib group and not-reached in the afatinib group (p=0.141). In patients with L858R mutation, the median PFS was 18.9 months in the erlotinib group and 16.2 months in the afatinib group (p=0.481). Conclusion Our research demonstrates that not only erlotinib combined with bevacizumab, but also afatinib plus bevacizumab as first-line treatment, provides solid clinical efficacy in advanced EGFR-mutant lung adenocarcinoma patients.

Hwa-Shin Fang,Chih-Ying Chao,Chun-Chieh Wang,Wen-Lang Fan,Po-Jung Huang,Hon-Chung Fung,Yih-Ru Wu 대한파킨슨병및이상운동질환학회 2022 Journal Of Movement Disorders Vol.15 No.1

A meta-analysis of locus-based genome-wide association studies recently identified a relationship between AXIN1 and Parkinson’s disease (PD). Few studies of Asian populations, however, have reported such a genetic association. The influences of rs13337493, rs758033, and rs2361988, three PD-associated genetic variants of AXIN1, were investigated in the present study because AXIN1 is related to Wnt/β-catenin signaling.
