基于Needs甲基化法枸杞多糖指纹图谱的建立

目的多糖是枸杞中主要的活性成分,各产地间枸杞多糖的结构和含量均有差异。目前枸杞多糖的质量控制方法大多都通过单糖组成构建指纹图谱,但仅通过单糖指纹图谱对枸杞多糖进行质量控制,并不能系统地对不同产地的枸杞多糖进行质量控制。因此,我们在单糖指纹图谱的基础上,利用Needs甲基化法确定枸杞多糖的糖残基连接方式,建立Needs甲基化法枸杞多糖指纹图谱,实现对不同产地枸杞的质量控制。方法通过水提醇沉法获得枸杞多糖,并采用Needs甲基化、完全酸水解、硼氢化钠还原及乙酰化等方法结合GC-MS测定枸杞多糖的糖残基连接方式。结果将18批枸杞多糖的糖残基连接方式色谱图导入《中药色谱指纹图谱相似度评价系统》(2004版)构建出指纹图谱,并结合多种化学计量法评价不同产地间枸杞多糖的差异。相似度计算结果发现,除西藏自治区三批枸杞多糖相似度0.551-0.569,其余15批样品相似度均0.929以上。糖残基连接方式色谱图共标定了16个共有峰,指认了其中10个共有峰,分别为TArap、T-Araf、T-Xylp、1,2-Arap、1,3-Rhap、1,5-Araf、T-Glcp、T-Galp、1,4-Glcp、1,6-Galp。HCA、PCA和PLS-DA分析结果将18批次不同产地的枸杞多糖分为3类,并筛选出了3个标志性成分,分别为T-Araf、1,5-Araf和T-Glcp,以此来判断不同产地间枸杞多糖的差异性。结论首次建立了18批枸杞多糖的Needs甲基化法指纹图谱,为枸杞多糖质量控制提供实验数据参考,进一步证明了多糖在中药质量控制中的作用。

The Oral Health Status of Person with Special Needs in Kumasi

Background: The most prevalent non-communicable disease worldwide is oral health-related disease, with dental caries and periodontal conditions being common. Oral health status significantly impacts overall health and quality of life. Barriers to dental care affect children with special needs. This study evaluates the oral health status and treatment requirements of people with special needs. Methodology: This descriptive cross-sectional study in Kumasi, Ghana examined oral health status among people, 121 children with special needs over two months, in June-July 2022. Dental caries, periodontal changes, malocclusion, and trauma were assessed. The data was analyzed using SPSS 20.0. Results: The oral health status among people with special needs in this study was generally moderate, with a range from very good to very poor. The prevalence of dental caries was 37%, with a mean DMFT score of 2.82. Periodontal health showed unsatisfactory indicators such as mobile teeth, poor gingival health, high plaque scores, and the presence of halitosis. Conclusion: This descriptive study aimed to provide baseline data on the oral health status of special needs students in Kumasi, addressing the lack of knowledge in this area. It highlighted the importance of dental care in maintaining good oral health and overall well-being in individuals with special needs. Coordinated efforts by dental professionals are needed to provide dental health education and preventive interventions for these children.

Validity assessment and determination of the cutoff value for the Index of Complexity, Outcome and Need among 12-13 year-olds in Southern Chinese

To validate the use of the Index of Complexity, Outcome and Need （ICON） in assessing orthodontic treatment need among 12-13 year-olds in southern China, we determined the threshold value of ICON based on Chinese orthodontists＇ judgments. The samples consisted of 335 students in grade 7 from 16 randomly selected middle schools in Chengdu, China. Three associate professors provided ICON scores for each participant and the results were compared with the gold standard judgments from 25 experts on treatment needs. Based on the gold standard, 195 casts belonged to the treatment category, while the rest 140 belonged to the no-treatment category. With the international cutoff point of 43, the sensitivity and specificity of the iCON score were 0.29 and 0.98. The best compromise between sensitivity and specificity in Chengdu, compared with the gold standard, was found at a cutoff point of 29, and the sensitivity and specificity were 0.88 and 0.83. When used to evaluate the treatment need of 12-13 year-olds in southern China, the international ICON cutoff value did not correspond well with Chinese orthodontists＇ judgments; a lower cutoff value of 29 offered a ~reater sensitivitv and soecificitv with respect to exoert orthodontists＇ oerceotion of treatment need.

English Language Assistance Needs of Chinese Students

It is known that the IELTS test has not been a good predictor of English capability in academic settings. More information is required. Are students not motivated to keep improving their English; what obstacles do they face? The English language issues facing international students from China at one University are explored through a survey and focus groups. It is observed that a lack of motivation is not the key factor. Rather one core problem is the very difficult demands of acculturation within a short time frame which would enable confidence for the students to continue to engage with other English speaking students. When faced with such immediate and hard to achieve acculturation, many retreat to their language groups. In the academic context, support for the transition to discipline based academic genres is double difficult as the time frame for second language learners is longer, but performance requirements are more immediate. Many first language students also have difficulties in this area, but have the easier language path to mastery. The study draws usefully on a comparison made with students studying English in China.

消费需求中的“NEEDS”与“WANTS”

在英文中,消费需求包括“Needs”和“Wants”,有人把它们分别译为“需求”或“欲望”、“需要”和“想要”,也有人用“生理需要”和“心理需要”,或“物质需要”与“精神需要”来区分。从意思上讲,这些表述都是有道理的,但从“Needs”和“Wants(也有人用‘desires’)”的定义和表述的简洁来讲,本人更愿意把它们表述为“需求”和“欲求”,即消费者“求其所需”和“求其所欲”的意思。从消费需求的发展来看,二者的区别越来越小,甚至可以互换使用;所以,通常情况下,我们只使用“消费需求”这一概念,而不再对二者进行严格的区分。

Needs Analysis of English Culture Background Introduction in Spoken English Classes

With globalization there is an increasing need for spoken English for Chinese college students. However, the situation of the teaching system of spoken English in most universities in China is not satisfactory. Influenced by the exam-oriented teaching system, great importance has been put on English grammar and the skills of reading and writing. As a result, students'enthusiasm in improving their spoken English is diminished. Actually, students need some knowledge about English culture background before they can communicate effectively. It is significant for teachers to find out the students'wants and lacks during their spoken English study. Besides, attentions should be paid to English culture background in spoken English classes by both teachers and students. This paper mainly aimed at finding out the needs of students for English culture background in spoken English classes based on the theory of needs analysis.
