The complete mitochondrial genome of a threatened loach (Sinibotia reevesae) and its phylogeny
Yuan‑Chao Zou,Bi‑Wen Xie,Chuan‑Jie Qin,Yong‑Ming Wang,Deng‑Yue Yuan,Rui Li,Zheng‑Yong Wen 한국유전학회 2017 Genes & Genomics Vol.39 No.7
In present study, the complete mitochondrial genome of Sinibotia reevesae was first sequenced using the next-generation sequencing technology and annotated using bioinformatic tools. The circular mitochondrial genome was 16,572 bp in length, and contained 13 proteincoding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and 1 displacement loop locus. It presents a typical gene organization and order for completely sequenced cypriniformes mitogenomes. The control region could be divided into three parts included the extended termination associated sequence domain, the central conserved domain and the conserved sequence block. Interestingly, two stemloop domains were found in control region and OL region, respectively. Furthermore, phylogenetic analyses using concatenated amino acid and nucleotide sequences of the 13 protein-coding genes with two different methods (Maximum likelihood and Bayesian analysis) both highly supported the close relationship of S. reevesae and Sinibotia superciliaris, which was in line with the previous classifications based on morphological and molecular studies. These data provide useful information for a better understanding of the mitogenomic diversities and evolution in fish as well as novel genetic markers for studying population genetics and species identification.

Golden-leaf privet ( Ligustrum × vicaryi ) is widely used as a horticultural shrub because of its upper golden leaves, butits lower leaves are green. However, the putative mechanisms of its upper golden leaves and the leaf color changes inresponse to light shifts have not been well studied so far. Here, chlorophylls (Chl), carotenoids, and Chl precursors from bothgolden and green leaves grown in full sunlight (approximately 1200 μmol photons m −2 s −1 at noon) or low-light conditions(180 μmol m −2 s −1 ) were determined spectrophotometrically. In addition, their gas exchange parameters and Chl fl uorescencewere measured in situ. Metabolic fl ux analysis of chlorophyll intermediates indicated that the conversion of prochlorophyllideto chlorophyllide was signifi cantly blocked in golden leaves when compared with green leaves. Green leaves showed higherphotosynthetic capacity in low light than golden leaves, but golden leaves presented unexpectedly stronger photosyntheticcapacity and lower reactive oxygen species accumulation under the high-light condition. Furthermore, golden leaves showeda higher level of nonphotochemical quenching (NPQ) after the light-to-dark shift and presented a stronger adaptive abilityto a broad range of light environments. Higher NPQ values and less oxidative damage in golden leaves may be correlatedwith their higher carotenoid levels. The results imply that lower chlorophyll levels and higher carotenoid levels in canopyleaves may help privet plants acclimate better to illumination changes. This study demonstrates the key role of irradiance ingenerating the two types of Ligustrum × vicaryi leaves and sheds a light on cultivation of other ornamental foliage plants.

Effects of light on phenolic compounds and antioxidant activities during germination of soybean seeds were studied. Soybean seeds were germinated in the presence and absence of light. Chlorophylls and morphological characteristics of sprouts were evaluated daily. Antioxidant activities were determined using 2,2-diphenyl-1-picryl-hydrazyl (DPPH) and ferric reducing activity power methods. Morphological characteristics of light-grown sprouts were superior to dark-grown sprouts and the metabolism of phenolic compounds was regulated by light. Light treatment improved accumulation of phenolic compounds in soybean sprouts and increased antioxidant activities. The optimum harvest time of light-grown sprouts was on the seventh day when sprouts achieved the best nutraceutical value. Green sprouts can serve as a good vegetable source for the human diet.
民初 아동문학가 당소포(唐小圃)의 생평 및 저술•번역 작품 고론

The term《童話》first appeared in the Commercial Press 'Fairy Tale'《童話》 series in 1909 edited by the pioneer of Chinese children's literature, Yuxiu Sun (孫毓修). Since then, together with the promotion and encouragement from Xun Lu (魯迅), Zuoren Zhou (周作人) and Yuanren Zhao (趙元任), an era of Chinese fairy tale translations began. Xiaopu Tang (唐小圃) (1879-?) was an active author of Chinese children’s literature during the May Fourth period. He translated and edited numerous works with Commercial Press after 1921 including "Jingyu Fairy Tales"《京語童話》, "Family Fairy Tales"《家庭童話》, "Women's Fairy Tales"《女子童話》 and "Russian Fairy Tales"《俄國童話集》, etc. His translation of Russian writings, the Literature Series for Children by Lee Tolstoy《托爾斯泰兒童文學類編》published in 1923, is the earliest Chinese version of written book introducing the work of Lee Tolstoy. This publication has ground-breaking impact on providing children with a good knowledge in Russian literature, and soon made him the successor of Sun Jixiu in children's literature. Xiaopu Tang was not only famous in literary works for children, he also translated a decent amount of short stories from the Meiji period in Japan and made comments at the end. Xiaopu Tang was very talented in both law and literature. However, few people are aware of his works in academic as time goes by. His single works are also dispersed in the journal《小說世界》and not collected for publication. Therefore, his contribution in Chinese literature is forgotten. In this study, we aim to bring back the value of Tang's works he deserves in the history of Chinese children’s literature. To do so, this paper starts with a brief introduction of his life. After that, we examined and analyzed his writing methodology and approach during the May Fourth period by collecting and reviewing his translation works for fables and novels from Russia and the Meiji period in Japan. We hope this study can help to recognize the life achievement of Xiaopu Tang, as well as his importance in the history of translation and children’s literature. 중국 아동 문학의 개산 조사인 손육수(孫毓修)는 1909년에 商務印書館에서《童話》총서를 편집했을 때 처음으로「童話」라는 어휘를 사용했다. 그 후 魯迅, 周作人 및 趙元任 등 문인들의 추진 아래 중국 동화를 번역하는 열풍이 일어났다. 唐小圃(1879-?)는 五·四 시기 아동 문학계에서 활약했고, 1918년 이후에도 商務印書館에서《京語童話》,《家庭童話》,《女子童話》및 《俄國童話集》……등 많은 아동 문학 작품을 잇달아 번안하고 출판했다. 특히 1923년에《托爾斯泰兒童文學類編》을 번역했는데, 이 작품은 현대에서 아동을 겨냥하고 白話文형식과 아동의 어조 및 필법으로 톨스토이 문학을 소개하는 첫 번째의 번역 작품이다. 唐小圃는 중국 아동이 러시아 문학을 깊이 있게 이해하는데 첫 번째 창작의 공을 세웠고, 아동 문학 분야에서 孫毓修의 후계자가 되었다. 아동 문학 작품을 번역하는 것으로 그 시대에 유명했던 唐小圃는 일본 메이지 시기의 단편 소설도 많이 번역했고, 또한 번역문의 뒤에 後記 형식으로 일본 메이지 소설 문학에 대해 비평을 했다. 民國시대에 唐小圃는 법학과 문학을 겸한 귀재였다. 그러나 시대의 흐름에 따라 그 身世는 학계에 알려지지 않고 있다. 번역한 단편 작품은 잡지《小說世界》에 드문드문 보여 찾아보기 힘들고 또한 책으로 출판되지 않기 때문에 학계에서 점차 잊히게 된다. 唐小圃를 전면적으로 이해하기 위해 본고는 그의 생애를 고증하고, 唐小圃가 창작한 작품과 러시아 및 일본 메이지 시대의 우화·소설을 번역한 작품들을 수집 정리한 후 唐小圃의 창작 및 번역 작품을 5·4 운동의 배경에서 분석해 볼 것이다. 본고는 唐小圃의 생애와 아동문학 및 번역문학사 시대를 배경으로 한 학술적 의미를 학계에 새롭게 인식시키기 바란다.

Objective: Interferon-${\gamma}$ (IFN-${\gamma}$) and signal transducers and activators of transcription (STATs) each play an important role in carcinogenesis associated with viral infection. Cervical cancer is almost invariably associated with infection by human papillomavirus (HPV), and previous studies suggested that dysregulation of the signal pathway involved in IFN-${\gamma}$ and STATs is associated. Our objective was to evaluate the association of SNPs in STAT2, STAT3, and IFN-${\gamma}$ with cervical cancer susceptibility in Chinese Han women in Hunan province. Materials and Methods: Genomic DNA was extracted from peripheral blood samples of 234 cervical cancer patients and 216 healthy female controls. STAT2 and STAT3 genotyping was performed using polymerase chain reaction-restriction enzyme (PCR-RE) analysis. IFN-${\gamma}$ genotyping was detected by PCR-amplification of specific allele (PASA). Results: For STAT2 rs2066807 polymorphisms, there was no significant difference of genotype distribution (P=0.827) and allele frequencies (P=0.830, OR=1.09, 95% CI: 0.51-2.31) between cases and controls. For STAT3 rs957970 polymorphisms, there was no significant difference of genotype distribution (P=0.455) and allele frequencies (P=0.560, OR=0.92, 95% CI: 0.71-1.20) between cases and controls. For IFN-${\gamma}$ +874A/T polymorphisms, there was no significant difference of genotype distribution (P=0.652) and allele frequencies (P=0.527, OR=1.12, 95% CI: 0.79-1.59) between cases and controls. Conclusion: These results suggest that polymorphisms in STAT2, STAT3 and IFN-${\gamma}$ genes are not likely to be strong predictors of cervical cancer in Han women in southern China.

Aims: TASL HCV Registry (TACR) is a nationwide registry program organized and supervised by Taiwan Association for the Study of the Liver (TASL), which aims to setup the database and biobank of patients with chronic hepatitis C (CHC) in Taiwan. The present study aimed to evaluate the treatment outcome of sofosbuvir (SOF)/ledipasvir (LDV) in Taiwanese CHC patients in TACR. Methods: By May 2020, 19 tertiary hospitals, 23 community hospitals and one primary care clinic join the TACR program. The baseline characteristics, prior liver and non-liver related medical history, DAA regimens, laboratory results, treatment course and outcome were recorded. The primary objective was sustained virological response, defined as undetectable HCV RNA 3 months after end-of-treatment (SVR12). Results: A total of 4742 SOF/LDV+ ribavirin treated CHC patients with available SVR12 data from 39 sites were enrolled in the current analysis. The mean age was 61.3 years, and female accounted for 54.8% of the population. The dominant viral genotypes were GT1b (52.6%) and GT2 (35.6%). 1354 (28.6%) patients had liver cirrhosis, including 156 (3.3%) with liver decompensation, 552 (11.6%) had preexisting hepatocellular carcinoma (HCC) before DAAs treatment and 413 (8.7%) had hepatitis B virus dual infections. The overall SVR12 rate was 98.5%, with 98.5%, 98.2%, 99.7% and 98.6% in treatment- naïve non-cirrhotics, treatment-naïve cirrhotics, treatment- experienced non-cirrhotics and treatment-experienced cirrhotics patients, respectively. While patients were stratified by HCV genotype, the SVR12 was 98.5%, 98.4% and 98.5% among those with GT1, GT2 and GT6 infection, respectively. The strongest factor independent associated with treatment failure was DAA adherence < 60% (odds ratio [OR]/95% confidence intervals [CI]: 125.4/25.7-612.4, P<0.0001), followed by active HCC (OR/CI: 6.20/2.57-14.97, P<0.0001), HIV co-infection (OR/CI: 3.01/1.14-7.92, P=0.026), and male gender (OR/ CI: 1.85/1.09-3.13, P=0.023). The eGFR decreased significantly at the end of treatment (EOT) (89.3 ml/min/1.73㎡ vs. 93.2 ml/min/1.73㎡, P< 0.001) and remained stable 3 months after EOT (89.3 ml/min/1.73㎡). However, the decreased eGFR was observed only in patients whose baseline eGFR > 90 ml/ min/1.73㎡. Instead, patients with chronic kidney diseases whose pretreatment eGFR < 60 ml/min/1.73㎡ had improved eGFR after SOF/LDV. Conclusions: SOF/LDV is highly effective in treating CHC patients in real-world setting of Taiwan. The satisfactory result could be explicitly generalized to patients with different viral genotypes and liver disease severities.

Background: Lianhuaqingwen (LH) has been proven effective for influenza. However, the promotion of LH for the treatment of patients with COVID-19 remains controversial. Therefore, our study aimed to assess the efficacy and safety of Lianhuaqingwen (LH) in treating patients with COVID-19 by a systematic review and meta-analysis. Methods: We conducted the literature search using six electronic databases from December 1, 2019, to June 2, 2020. Cochrane Risk of Bias tool was used to assess the quality of randomized controlled trials. Newcastle-Ottawa Scale was used to assess the quality of case control studies. Agency for Healthcare Research and Quality checklist was used to assess the quality of case series. All analyses were conducted by RevMan 5.3. For outcomes that could not be meta-analyzed were performed a descriptive analysis. Results: Eight studies with 924 patients were included. Three studies were RCTs, three were case control studies, and two were case series. The quality of the included studies was poor. Compared with patients treated by conventional treatment, patients treated by LH combined with conventional treatment have a higher overall effective rate (RR = 1.16, 95%CIs: 1.04∼1.30, P = 0.01) and CT recovery rate (RR=1.21, 95%CIs: 1.02∼1.43, P = 0.03). Patients of LH groups have a lower incidence of diarrhea (5.6% vs.13.4%), and have statistically significant (P = 0.026). But the rate of abnormal liver function in the combined medication group is higher than that in the single LH group. Conclusion: LH combined with conventional treatment seems to be more effective for patients with mild or ordinary COVID-19.

Ming Yuan,Wenxian Zhu,Jiaxing Lv,Panpan Zhang,Huadong Tang 한국고분자학회 2021 폴리머 Vol.45 No.3
In this work, a series of hydrosilanes including phenylsilane, diphenylsilane, triethylsilane (TES), and tris(trimethylsilyl)silane combined with catalytical amount of platinum complex such as dichloro(1,5-cyclooctadiene) platinum (COD) and dichloro(dicyclopentadienyl)platinum have been used to initiate the polymerization of vinyl acetate (VAc) at 70-95 ℃. An ultrahigh molecular weight PVAc with number-average molecular weight (Mn) up to 1.17×10<SUP>6</SUP> Da and polydispersity index (PDI) of 2.59 has been synthesized using TES as an initiator in the presence of 9.7 ppm of COD. A kinetic study indicates that the polymerization at VAc/TES/COD molar ratio = 3.0×10<SUP>5</SUP> : 60 : 1 smoothly reached 81.0% conversion in 28.0 h at 85 ℃, producing PVAc with Mn increasing linearly from 1.41×105 to 6.01×10<SUP>5</SUP> Da with the increase of monomer conversion. A mechanistic investigation revealed that COD was firstly reduced by reductive TES, producing Pt nanoparticles and corresponding silane radicals to initiate the polymerization of VAc.

Ming-Yuan Tang,Chih-Mei Yang,Hank Jun-Ling Jwo 대한운동학회 2021 아시아 운동학 학술지 Vol.23 No.3
[OBJECTIVES] The perceptual ability to detect movement is essential for expert table tennis players. A spatiotemporal occlusion paradigm was employed to examine the critical information that facilitates athletes’ perception. [METHODS] Thirty-one expert table tennis players, 29 participants and 2 demonstrators, volunteered to participate in the study. Four types of temporal conditions and five types of spatial occlusions were displayed in experimental videos of two opponents playing a table tennis forehand stroke. Period t1-4 represented the four temporal conditions, with 250, 500, 750, and 1000 ms of action being occluded, respectively. The five types of spatial occlusion involved showing the kinematics of only the ball, paddle, arm, trunk, or head. The participants were instructed to judge the landing direction of the ball on the basis of the information in the footage. [RESULTS] The footage depicted the longest period of play. Furthermore, in separate trials, the spatial information (for the ball, torso, or head) was missing because of occlusion. The absence of such critical spatiotemporal information impaired the ability of players to make an accurate prediction. [CONCLUSION] Players obtained crucial spatiotemporal information if the timeframe of the video was relatively complete and spatial information on the opponent’s torso and head was available. For peak performance, expert table tennis players perceive and detect the optical flow of the ball’s flight and consider invariant information concerning their opponent’s torso and head.
