BACKGROUND Limited knowledge exists regarding the casual associations linking blood metabolites and the risk of developing colorectal cancer.AIM To investigate causal associations between blood metabolites and colon cancer.METHODS The study utilized a two-sample Mendelian randomization(MR)analysis to investigate the causal impact of 486 blood metabolites on colorectal cancer.The primary method of analysis used was the inverse variance weighted model.To further validate the results several sensitivity analyses were performed,including Cochran's Q test,MR-Egger intercept test,and MR robust adjusted profile score.These additional analyses were conducted to ensure the reliability and robustness of the findings.RESULTS After rigorous selection for genetic variation,486 blood metabolites were included in the MR analysis.We found Mannose[odds ratio(OR)=2.09(1.10-3.97),P=0.024],N-acetylglycine[OR=3.14(1.78-5.53),P=7.54×10^(-8)],X-11593-O-methylascorbate[OR=1.68(1.04-2.72),P=0.034],1-arachidonoylglycerophosphocholine[OR=4.23(2.51-7.12),P=6.35×10^(-8)]and 1-arachidonoylglycerophosphoethanolamine 4[OR=3.99(1.17-13.54),P=0.027]were positively causally associated with colorectal cancer,and we also found a negative causal relationship between Tyrosine[OR=0.08(0.01-0.63),P=0.014],Urate[OR=0.25(0.10-0.62),P=0.003],N-acetylglycine[0.73(0.54-0.98),P=0.033],X-12092[OR=0.89(0.81-0.99),P=0.028],Succinylcarnitine[OR=0.48(0.27-0.84),P=0.09]with colorectal cancer.A series of sensitivity analyses were performed to confirm the rigidity of the results.CONCLUSION This study showed a causal relationship between 10 blood metabolites and colorectal cancer,of which 5 blood metabolites were found to be causal for the development of colorectal cancer and were confirmed as risk factors.The other five blood metabolites are protective factors. 展开更多

This article reflects on the process of transcribing spoken interaction and makes a comparative analysis of two different varieties of spoken interaction(casual conver- sation and institutional talk). By doing so, it reveals how the different purposes of speech result in their distinctive characteristics, and shows how language is struc- tured to construct ideational meanings(Field) and interpersonal meanings(Tenor) that define each context. 展开更多

This study attempted to examine the importance of storeenvironment in affecting consumers’store choice deci-sion;the relative importance among the three environ-mental factors;and consumers’expectations on store en-vironment for the casual-wear chain stores in HongKong.Julie Baker’s Three-category framework onstore environments namely ambient,design and socialfactors was adopted for investigation.The results indi-cated that the store environment was important in affect-ing consumers’selection of store for shopping.It alsorevealed that social factor was perceived relatively im-portant than ambient and design factors.Nine store ex-pectation dimensions were categorised and the resultdemonstrated that most respondents were concerned onthe social aspect in their expectation of having a satisfy-ing store environment. 展开更多

Background: The gap in the understanding of the context of the sexually transmitted infections (STIs) and risky behaviours among men who have sex with men (MSM) could lead to the development and implementation of inappropriate interventions, which could exacerbate the rapid spread of STIs, especially HIV, among MSM. The aim of the study was to qualitatively assess the understanding of the STIs and the risky sexual behaviours of men who have sex with men in the North-West region of Tshwane. Methods: An exploratory qualitative design was employed to assess the STIs and the risky sexual behaviour of the MSM population. The study participants were enrolled in an HPV clinical trial at MECRU, which is a clinical research unit at the Sefako Makgatho Health Sciences University. Data collection occurred from September 2016 to May 2017. A convenience sampling method was used and n = 30 participants were selected. Face-to-face in-depth interviews were conducted on MSM 18 years and older, using a semi-structured interview guide. Thematic content analysis was used for data analysis, using NVivo version 10 software. Results: The mean age of the sample was 26 years, and the age range was 18 to 44 years. All were unmarried, and all of them came from townships, rural villages and informal settlements in the vicinity of the clinical research unit. The high-risk behaviours noted among the majority of the MSM in this study were having multiple sexual partners and exchanging partners, alcohol abuse, inconsistent condom-use, having unprotected anal sex, and having transactional sex. There was a high level of knowledge of STIs in the heterosexual population with poor understanding of STIs affecting MSM through anal sex. Most of the MSM played a female or bottom role, which made them vulnerable because they could not successfully negotiate condom use, and they reported that they sometimes accepted gifts or money in exchange for anal sex. Conclusion: The study concludes that the MSM in this study had casual sex, and are involved in sex work without practising safe sex. There is a need for health promotion on STIs and risky behaviours among MSM in communities as well as in health facilities for MSM in the North-West region of Tshwane. 展开更多

The theory of "thick translation", put forward by American scholar Kwame Anthony Appiah, suggests understanding and translating source text with the help of its rich cultural and linguistic context. The notion boasts a significant role in the translation of ancient Chinese classics which is the embodiment and condensation of traditional Chinese philosophical principles, such as Taoism, Confucianism. This paper mainly looks into the translation of culture-loaded words in Casual Expressions of Idle Feeling from the perspective of"thick translation"and wishes to contribute to the strategies of translating culture-loaded words in ancient Chinese classics. 展开更多
