精神病药物阿立哌唑的作用机理

精神病药物阿立哌唑的作用机理杨雯雁〔09354065〕柯玉娟〔09354097〕袁媛〔09354102〕郑小丽〔09354093〕温璐平〔09354121〕【摘要】1988年阿立哌唑的发现，是受精神分裂症的几种优势病因假说指导。

经历的Ⅰ、Ⅱ和Ⅲ期临床试验提示，阿立哌唑具有起效快、平安性高及耐受性好等临床特性。

多年来人们一直在探讨阿立哌唑的作用机制，其中有两种较为权威的说法。

其一，多巴胺假说。

认为脑内多巴胺能神经递质异常引起精神分裂症病症。

其二，血清素假说。

认为多巴胺的活动,受血清素能神经元调节。

我们小组旨在研究对抗最典型的精神类疾病——精神分裂症的药物作用机理的同时，增加自己的生物化学课外知识，锻炼小组合作和深入探讨和研究的能力。

【关键词】阿立哌唑；精神分裂症；多巴胺受体；作用机制一、我们选择研究精神分裂症药物的原因以及研究精神疾病的意义人类有很长一段历史对精神卫生健康的关注是一片空白。

人们片面地以为身体健康就能百分之百衡量一个人的健康程度。

然而大多数人不知道，精神健康在很大程度上影响着人们的正常生活和工作学习的进度，不健康的精神状况不仅会使自身遭受痛苦，同时也带给周围的家人朋友很大的负担。

精神疾病在古时候被认为是和宗教中的恶魔或者巫术有关，这样的误解不仅耽误了对精神病人的及时治疗，也使历史上对精神疾病这一领域的科学研究停滞不前。

1991年，尼泊尔提交了第一份关于“世界精神卫生日〞活动的报告。

由此拉开了人们关注人类精神健康的序幕。

随后的十多年里，许多国家参与进来，世界卫生组织确定将每年的10月10日作为特殊的日子“世界精神卫生日〞，提高公众对精神疾病的认识，分享科学有效的疾病知识，消除公众的偏见。

目前全世界共约有亿各类精神和脑部疾病患者，每4个人中就有1人在其一生中的某个时段产生某种精神障碍，精神卫生已经成为一个突出的社会问题。

至今，精神卫生健康已成为人类健康的一大重要领域。

Anxiolytic effect of music exposure on BDNFMetMet transgenic mice.

Conclusion
1)music exposure could induce an anxiolytic effect on BDNFMet/Met mice and the effect is at least in part mediated by the increased BDNF expression in the brain. 2)It has been reported that TrkB-overexpressed mice show reduced anxiety; although music exposure could upregulate TrkB mRNA level in BDNF+/− mice, it could not reduce the anxiety level, which suggested that BDNF is the main mediator in musicelicited anxiolytic effect. 3) This finding suggests that music may provide an effective therapeutic intervention for anxiety disorders in humans with this genetic BDNFMet variant.
BDNF protein levels by ELISA
In the control group, the BDNF protein level was significantly less in BDNFMet/Met and BDNF+/− mice in PFC and hippocampus; music treatment significantly increased BDNF protein levels in PFC, hippocampus, and amygdala.

我国猪瘟的流行病学及疫苗研究进展

·综述·Chinese Journal of Animal Infectious Diseases中国动物传染病学报我国猪瘟的流行病学及疫苗研究进展摘要：猪瘟（CSF ）是由猪瘟病毒（CSFV ）引起的一种严重危害全球养猪业的高度接触性传染病，因其发病率和死亡率都很高，对经济造成巨大的损失，被OIE 列为必须通报的动物传染病。

我国将疫苗接种作为防控CSF 的主要手段，但由于疫苗的长期使用、温和毒力毒株的出现以及持续性感染的存在，使我国CSFV 流行株的变异呈多样性，且以远离疫苗株的变异为主。

因此，持续开展我国CSFV 流行毒株分子生物学和流行病学研究，研发能够区分疫苗野毒抗体，且提供高效免疫保护的新型基因工程疫苗，对我国CSF 的有效防控和最终净化具有重大意义。

本文重点对我国CSFV 的分子生物学特征及CSF 疫苗研究进展进行了综述，为CSF 防控提供参考。

Classical swine fever virus (CSFV) is highly contagious with high morbidity and mortality. As such, it is an OIE-listed disease. In China, vaccination is used as the main means for the prevention and control of CSF. Because of the long-term use of the vaccine, the emergence of mild virulent strains and presence of persistent infection, the diverse variations of CSFV epidemic strains are present in China, which vary far away from the vaccine strains. Therefore, it is very important to carry out the research on molecular biology and epidemiology of CSFV epidemic strains and develop new genetic engineering vaccines that can be differentiated from wild infection for the effective control and eradication of CSF in China. This paper focuses on the research progress of molecular biology of CSFV and vaccines, providing a reference for CSF prevention and control.Key words: Classical swine fever; classical swine fever virus; molecular epidemiology; vaccine; prevention and control2022,30(6):211-218马帅1，郑世磊2，赵明1，王媛1，张严琦1，邴啟政1，段笑笑1，曹志3（1.青岛市动物疫病预防控制中心，青岛266100；2.青岛易邦生物工程有限公司，青岛266114；3.青岛农业大学，青岛266109）· 212 ·中国动物传染病学报2022年12月猪瘟（Classical swine fever, CSF）也称猪霍乱，是由猪瘟病毒（Classical swine fever virus, CSFV）引起的猪和野猪的一种高度接触性、高致死性传染病，一年四季均可发生[1]。

大豆异黄酮对幼年小鼠生殖发育的影响

大豆异黄酮对幼年小鼠生殖发育的影响Δ许文达＊，董思林，张晗，宋迎琳，迟镜仪，赵振军，石慧 #（烟台大学生命科学学院，山东烟台　264005）中图分类号 R 965；Q 418 文献标志码 A 文章编号 1001-0408（2024）06-0678-05DOI 10.6039/j.issn.1001-0408.2024.06.07摘要目的探讨大豆异黄酮（SI ）对幼鼠生殖发育的影响。

方法将C 57BL/6幼鼠随机分为对照组和SI 小、大剂量组（10、100mg/kg ），每组10只，雌雄各半。

各药物组幼鼠灌胃相应药液，每天1次，持续2周。

末次灌胃后，计算幼鼠的体重增长百分比，检测血清雌二醇、睾酮水平以及生殖器官组织中丙二醛（MDA ）含量、总抗氧化能力（T-AOC ）和超氧化物歧化酶（SOD ）、谷胱甘肽过氧化物酶（GSH-Px ）活性，观察其生殖器官组织的病理改变，并检测其细胞凋亡情况。

结果与对照组比较，SI 大剂量组雌性幼鼠的体重增长百分比显著升高，而雄性幼鼠的体重增长百分比显著降低（P ＜0.05或P ＜0.01）。

SI 各剂量组幼鼠卵巢组织均可见囊性卵泡，睾丸组织可见精母细胞排列松散，附睾组织可见部分上皮细胞脱落。

SI 各剂量组雌性幼鼠血清睾酮水平和雄性幼鼠血清睾酮、雌二醇水平，SI 小剂量组雌性幼鼠卵巢组织中GSH-Px 活性和SI 各剂量组雌性幼鼠卵巢组织中T-AOC ，以及SI 各剂量组雄性幼鼠睾丸及附睾组织细胞凋亡率均显著升高（P ＜0.05或P ＜0.01）；SI 各剂量组雌性幼鼠血清雌二醇水平，SI 大剂量组雌性幼鼠卵巢组织中SOD 活性和SI 各剂量组雌性幼鼠卵巢组织中MDA 含量，以及SI 各剂量组雌性小鼠卵巢组织细胞凋亡率均显著降低（P ＜0.05或P ＜0.01）。

结论 SI 可提高雌性幼鼠卵巢组织的抗氧化应激能力，减少其氧化应激损伤，但对雄性幼鼠的生殖器官具有一定的蓄积毒性。

方法交叉滞后路径分析模型基于交叉滞后面板设计,估计的路径系数具有明确的时间顺序关系，满足因果推断中“因在前果在后”的时序性要求。

利用健康随访数据构建体重指数(BMI )与血尿酸(UA )的交叉滞后路径分析模型，探索BMI 和UA 的因果时序关系。

结果调整混杂因素后，基线BMI 到随访时UA 的路径系数(p 2 =0. 060,P <0.001)明显大于基线UA 到随访时BMI 的路径系数(P 1 = -0.009,P =0.056)，且两系数间的差异具有统计学意义(P 2 > P 1,P <0.001)。

在时间顺序上BMI 增加先于 UA 升高发生。

结论BMI 增加可能是高尿酸血症的原因，交叉滞后路径分析模型可以有效的识别变量间的因果时序关系。

Methods The cross-lagged path analysis model is based on the cross-lagged panel design , its path coefficient indicates a clear temporal sequence , which satisfies the temporality that cause precedes outcome in causal inference. We built a cross-lagged path analysis model to examine the temporal relationship between body mass index (BMI) and uric acid ( UA ) by using the longitudinal data. Results After adjusting for covariates , the path coefficient from baseline BMI to follow-up UA( p 2 =0. 060,P <0. 001) was significantly greater than the path coefficient from baseline UA to follow-up BMI(p 1 = -0. 009,P =0. 056) , with P <0. 001 for difference between p 〔 and p ?. Increased BMI levels precede higher UA levels. Conclusion Elevated BMI levels might lead to the development of hyperuricemia in later life. The cross-lagged path analysis model is an effective method for examining the temporal relationship between intercorrelated variables.[Key words ] Cross-lagged path analysis ；Temporal sequence ；Body mass index ；Uric acid实际研究中，通常利用因果图(casual diagram )的方式直观地标识危险因素之间的相关或因果关系，从而清晰地表达混杂效应、中介效应等多种因果推断的关键概念［l ］o 如图1所示的因果图模型,X 为解释变量,Y 为反应变量,Z 为另一个解释变量。

Brovana（arformoterol tartrate）吸入液患者指南说明书

DEPARTMENT OF HEALTH & HUMAN SERVICES Public Health ServiceFood and Drug AdministrationSilver Spring, MD 20993 Maria Anne RochaSenior Manager, Regulatory AffairsSunovion Pharmaceuticals Inc.84 Waterford Dr.Marlborough, MA 01752-7010RE: NDA # 021912BROVANA® (arformoterol tartrate) Inhalation SolutionMA # 382Dear Ms. Rocha:The Office of Prescription Drug Promotion (OPDP) of the U.S. Food and Drug Administration (FDA) has reviewed patient brochures titled Neb SABA Patient Type [BROV138-12], DPI Patient Type [BROV136-12], MDI Patient Type [BROV137-12], and Add-On Patient Type [BROV139-12], for BROVANA® (arformoterol tartrate) Inhalation Solution (Brovana) submitted by Sunovion Pharmaceuticals Inc. (Sunovion) under cover of Form FDA 2253. The patient brochures are misleading because they overstate the efficacy of Brovana, make unsubstantiated claims, including unsubstantiated superiority claims, and minimize the risks associated with the drug. Thus, the patient brochures misbrand the drug in violation of the Federal Food, Drug, and Cosmetic Act (FD&C Act), 21 U.S.C. 352(a). Cf. 21 CFR 202.1 (e)(6)(i), (ii); (e)(7)(viii).BackgroundBelow are the indication and summary of the most serious and most common risks associated with the use of Brovana.1 According to its FDA-approved product labeling (PI) (emphasis in original):BROVANA (arformoterol tartrate) Inhalation Solution is indicated for the long-term, twice daily (morning and evening) maintenance treatment ofbronchoconstriction in patients with chronic obstructive pulmonary disease(COPD), including chronic bronchitis and emphysema. BROVANA InhalationSolution is for use by nebulization only.Important Limitations of UseBROVANA Inhalation Solution is not indicated to treat acute deteriorations of chronic obstructive pulmonary disease[.]1 This information is for background purposes only and does not necessarily represent the risk information that should be included in the promotional pieces cited in this letter.BROVANA Inhalation Solution is not indicated to treat asthma. The safety and effectiveness of BROVANA Inhalation Solution in asthma have not beenestablished.Brovana is associated with a number of serious risks. The PI contains a Boxed Warning regarding asthma-related death as well as Contraindications in patients with a history of hypersensitivity to arformoterol, racemic formoterol, or to any other components of Brovana and in patients with asthma without the use of a long-term asthma control medication. The PI also contains Warnings and Precautions including deterioration of disease and acute episodes, excessive use of Brovana and use with other Long-Acting Beta2-Agonists (LABA), paradoxical bronchospasm, cardiovascular effects, coexisting conditions, hypokalemia and hyperglycemia, and immediate hypersensitivity reactions.The most common adverse reactions associated with Brovana during clinical trials were pain, chest pain, back pain, diarrhea, sinusitis, leg cramps, dyspnea, rash, flu syndrome, peripheral edema, and lung disorder.Overstatement of EfficacyPromotional materials are misleading if they contain representations or suggestions that a drug is better or more effective than has been demonstrated by substantial evidence or substantial clinical experience.Pages 1, 3, and 4 of each of the patient brochures contain the tagline (bolded emphasis in original), “Get back into daily living,” in conjunction with the Brovana trade dress. These claims, along with the headline claim (bolded emphasis in original), “With the right COPD medicine, you may get back to daily living[,]” on page 3 of each of the patient brochures, misleadingly overstate the efficacy of Brovana by suggesting that an outcome of treatment with Brovana is the ability for patients to resume their baseline activities of daily living. According to the CLINICAL STUDIES section of the PI, treatment with Brovana demonstrated an approximately 11% change in mean forced expiratory volume in one second (FEV1) from study baseline FEV1 at the end of the dosing interval over 12 weeks of treatment compared to placebo. Although Brovana may improve patients’ mean FEV1, we are not aware of substantial evidence or substantial clinical experience demonstrating that the magnitude of the effect the drug has on FEV1 taken together with any drug-related side effects (e.g., paradoxical bronchospasm, cardiovascular effects, pain, chest pain, back pain, diarrhea, sinusitis, leg cramps, dyspnea, rash, flu syndrome, peripheral edema, and lung disorder), results in an overall positive impact on patients’ ability to resume their baseline activities of daily living. If you have data to support these claims, please submit them to FDA for review. Unsubstantiated Superiority Claims/Unsubstantiated ClaimsPromotional materials are misleading if they contain a drug comparison that represents or suggests that a drug is safer or more effective than another drug, when this has not been demonstrated by substantial evidence or substantial clinical experience.Page 1 of the patient brochures includes the following headline claims, respectively (bolded emphasis in original):∙ “If you have COPD, Are you using your nebulizer sometimes 4 or more times a day?” (NEB SABA [nebulizer Short-Acting Beta2-Agonists] Patient Type brochure)∙ “If you have COPD, Do you feel you’re just not able to breathe in all your medicine?” (DPI [dry-powder inhaler] Patient Type brochure)∙ “If you have COPD, Is it hard for you to depress your inhaler and time your breaths to get your medicine out?” (MDI [metered dose inhaler] Patient Typebrochure)∙ “If you have COPD, Do you take your medicine correctly, but still feel like you may need something more?” (Add-On Type brochure)Furthermore, page 2 of each of the patient brochures includes the following presentation (bolded emphasis in original):“Do any of the statements below capture how you feel? Check the onesthat do.∙ I use my nebulizer sometimes 4 or more times a day__so it's often easier for me just to stay at home. Sometimes I even need it in the middle ofthe night∙When I use my inhaler, it just doesn’t feel like I’m able to breathe in all of my medicine, or that all the medicine is coming out∙My hands don’t move as well anymore, so it’s hard for me to use my inhaler. I have trouble timing my hands with my breathing∙I’m taking my medicine, but it feels like I may need something moreBring this with you into the exam room, and ask your doctor if BROVANA®(arformoterol tartrate) Inhalation Solution is right for you.”The totality of these claims and presentations as set forth in each of these brochures, along with the headline claim on page 3 of each of the brochures referenced above (“With the right COPD medicine, you may get back to daily living”), suggests that Brovana (the “right” COPD medicine) is clinically superior to other available COPD therapies. Specifically, these claims and presentations suggest that Brovana will be effective for patients who have not had success with other COPD therapies based on Brovana’s ability to overcome the potential challenges associated with these therapies, such as their respective dosing regimens (e.g., therapies dosed four or more times a day) or delivery systems (e.g., DPIs or MDIs). We are not aware of any adequate and well-controlled head-to-head studies supporting the implication that Brovana is clinically superior to other COPD therapies. We acknowledge that according to the CLINICAL STUDIES section of the PI, the trials associated with the approval of Brovana did include an active comparator, salmeterol. However, these studies were not designed to measure clinical superiority, and thus do not constitute substantial evidence tosupport these claims. If you have data to support these claims, please submit them to FDA for review.In addition, the claims above regarding the potential difficulty patients may encounter depressing an inhaler to administer therapy (e.g. “My hands don’t move as well anymore, so it’s hard for me to use my inhaler.”) are misleading because they imply that patients with compromised manual dexterity will more easily be able to administer Brovana as compared to other COPD inhaler therapies. We are not aware of any evidence to support these claims. Proper use of Brovana, as described in the Medication Guide, includes lengthy directions for use, which include opening a foil pouch and removing a ready-to-use vial, opening the ready-to-use vial, squeezing the medication out of the ready-to-use vial into the reservoir of a jet nebulizer, connecting the reservoir to either a mouthpiece or face mask, connecting the nebulizer tubing to the compressor, and cleaning the nebulizer after use. Therefore, in the absence of adequate evidence to demonstrate that patients with compromised manual dexterity are more easily able to administer Brovana as compared to other inhaled COPD therapies, the above claims are misleading.Minimization of Risk InformationPromotional materials are misleading if they fail to present information about risks associated with a drug with a prominence and readability reasonably comparable with the presentation of information related to the effectiveness of the drug. Factors impacting prominence and readability include typography, layout, contrast, headlines, paragraphing, white space, and other techniques apt to achieve emphasis. The patient brochures prominently present efficacy claims in large, bolded font size and colorful text and graphics surrounded by a significant amount of white space. In contrast, risk information is presented in small font, surrounded by little white space, and in single-spaced format. The overall effect of this presentation undermines the communication of important risk information, minimizing the risks associated with Brovana, and misleadingly suggests that Brovana is safer than has been demonstrated by substantial evidence or substantial clinical experience.Conclusion and Requested ActionFor the reasons described above, the patient brochures misbrand Brovana in violation of the FD&C Act, 21 U.S.C. 352(a). Cf. 21 CFR 202.1 (e)(6)(i), (ii); (e)(7)(viii).OPDP requests that Sunovion immediately cease the dissemination of violative promotional materials for Brovana such as those described above. Please submit a written response to this letter on or before November 7, 2013, stating whether you intend to comply with this request, listing all promotional materials (with the 2253 submission date) for Brovana that contain violations such as those described above, and explaining your plan for discontinuing use of such violative materials.Please direct your response to the undersigned at the Food and Drug Administration, Center for Drug Evaluation and Research, Office of Prescription Drug Promotion, 5901-B Ammendale Road, Beltsville, Maryland 20705-1266 or by facsimile at (301) 8478444.

广东省八校2024-2025学年高三上学期9月联合检测英语试题一、阅读理解China’s Best New Outdoor AttractionsWhen it comes to tourist attractions, here are a few of our favorites.The Grand Canal, the world’s longest human-made riverStretching 1, 782 kilometers, China’s Grand Canal is the world’s longest human-made river. Inscribed as a UNESCO World Heritage Site in 2014, the Grand Canal-also known as Jing-Hang Canal-runs from Beijing to Hangzhou and connects s to multiple waterways, including the Yellow River and the Yangtze River.Jiangsu Garden Expo ParkNanjing’s Garden Expo Park Scenic Spot showcases the region’s famous Jiangsu-style gardens. It is home to beautiful, classic Jiangsu-style gardens and other attractions, including a water botanical garden, a theater and a pedestrian shopping street. Among the highlights is Suzhou Garden, which was inspired by the Canglang Pavilion—a UNESCO World Heritage Site in nearby Suzhou.Universal Beijing ResortOpened in September 2021, the 169-hectare Universal Beijing Resort is the world’s fifth and largest Universal Studios theme park. There are seven themed lands offering dozens of shows and rides, many of them outdoors: The Wizarding g World of Harry Potter；Transformers Metrobase; Hollywood; WaterWorld; Minion Land；Jurassic World Isla Nublar; and Kung Fu Panda Land of Awesomeness.Glamping (豪华露营) and stargazing at Ningxia’s Desert Star Hotel Ningxia Hui Autonomous Region experiences little rainfall and enjoys around 300 days of clear skies yearly,making it one of the best places to enjoy China’s desert landscapes and engage in some serious stargazing. One of the top ways to experience Ningxia is by checking into the Desert Star Hotel in Ningxia’s Zhongwei City. The complex offers indoor and outdoor dining options, a swimming pool, an astronomy-themed theater and family-friendly sand activities. 1．Which attraction is listed as a UNESCO World Heritage Site?A．Jing-Hang Canal.B．Jiangsu Garden Expo Park.C．Universal Beijing Resort.D．Ningxia’s Desert Star Hotel.2．What does Universal Beijing Resort offer?A．Several dozen themed lands.B．Astronomy-themed movies.C．Outdoor shows and rides.D．A pedestrian shopping street.3．What can visitors do in Ningxia’s Desert Star Hotel?A．Attend a concert.B．Play with sand.C．Swim in the ocean.D．Enjoy classic gardens.Rowan Atkinson was born in a middle-class family. He had a speaking disability right from his childhood. This gave him a tough time in his childhood and at the start of his career. He was constantly bullied and laughed at because of his look and his speaking disability. This made him very shy and quiet. He didn’t have a lot of friends and the several rejections left him feel lonely. Rowan was very much interested in science. And he decided to pursue a career in this field.After he completed his Master’s degree, he realized acting was something he really wanted to pursue. He auditioned for several TV shows but faced back-to-back rejections, because he didn’t have a good face and grand body in addition to his stammering (口吃的) problem as well. Rowan kept his passion alive and worked hard towards reaching his dreams. He aimed at making people laugh and with persistent efforts over the years he has successfully established this.After the several rejections he started creating original comedy sketches. Interestingly he realized that whenever he played some characters, he spoke fluently. He used it as an inspiration for his acting. This is exactly where Rowan’s life changed.Rowan continued pursuing his dreams, despite all the hardships and rejections he had faced because of his looks and disorder. He had a major breakthrough when he started his own show Mr. Bean. Mr. Bean was “strange, surreal and non-speaking character”. He proved that even without a Hollywood face or a heroic body, you can become one of the most loved and respected actors in the world.Life always rewards those who are willing to keep moving forward. He teaches us that for success all you really need is hard work. Never let your fears and disabilities stop your life. Walk past these and make yourself better. Your hard work and efforts are sure to pay off one day. 4．What can we know about Rowan when he was young?A．He liked bullying his classmates.B．He had a few friends and felt lonely.C．He showed little interest in science.D．He recovered from his speaking disability.5．Why did Rowan want to act?A．He wanted to become popular.B．He enjoyed staying in the stage.C．He intended to make people happy.D．He was eager to overcome his drawback. 6．What made Rowan’s life change?A．That he was respected by the audience.B．That he could speak fluently in some characters.C．That he got a Hollywood face and a herbic body.D．That he received a. Master’s degree in science.7．What contributed to Rowan’s success according to the text?A．His wisdom B．His independence.C．His honesty.D．His willpower.Human beings are not alone in having invented vaccination, while honeybees got there first and they can run what look like vaccination programmes, which has been confirmed by Gyan Harwood of the University of Illinois, Urbana-Champaign.Queen bees vaccinate their eggs before they are laid. But the question is how the queen receives her antigen supply, for she lives purely on royal jelly, a substance secreted by nurse bees when they are in the life stage of feeding the young. Dr Harwood wondered if the nurses combined the royal jelly they produced with pieces from pathogens they had consumed while eating something brought in from outside.To test this idea, they collected about 150 nurse bees and divided them among six queenless mini hives equipped with the young to look after. They fed the nurses on sugar-water, and for three of the hives they added Paenibacillus larvae, a bacterium causing a disease, to sugar-water.Dr Harwood and Dr Salmela labeled the bacteria with a certain dye, to make them easy to track. And, sure enough, microscope confirmed that Paenibacillus larvae were getting into royal jelly secreted by those bees which had been fed with the sugar-water. Moreover, examination of this royal jelly revealed higher levels of defensive substance, compared with royal jelly from bees that had not been mixed with Paenibacillus larvae. This substance is thought to help bee immune systems fight against bacterial infections.All told, these findings suggest that nurse bees are indeed, via their royal jelly, passing antigens on to the queen, then into eggs. They also mean, because the young receive royal jelly forthe first few days after they hatch, the nurses are giving the young the second antigens. Each young bee is therefore being vaccinated twice.8．What puzzled Dr Harwood from paragraph 2?A．What the royal jelly consists of.B．Where nurse bees receive pathogens.C．How the antigen come into the queen bees' bodies.D．Whether honeybees run vaccination earlier than man.9．How did Dr Harwood develop his experiment?A．By dividing bees into different roles.B．By keeping track of the special bacterium.C．By changing the components of royal jelly.D．By observing nurse bees' different behaviors.10．What can we infer according to the results of the experiment?A．Nurse bees are the key to vaccination for bee group.B．The nurse bees pass the antigen only to the queen.C．Bacteria-used royal jelly has fewer defense substances.D．Two vaccinations are given to young bees by caregivers directly.11．Where is the text probably taken from?A．A pet guide.B．A social website.C．An official document.D．A medical magazine.The British has obeyed the “keep to the left” rule for long. Have you ever wondered why? There is a historical reason for this: it’s all to do with keeping your sword hand free! In the Middle Ages you never knew who you were going to meet when travelling on horseback. Most people are right-handed, so if a stranger passed by on the right of you, your right hand would be free to use your sword if required.Indeed the “keep to the left” rule goes back even further in time; archaeologists have discovered evidence suggesting that the Romans drove carts and wagons on the left, and it is known that Roman soldiers always marched on the left. This “rule of the road” was officially sanctioned in 1300 AD when Pope (教皇) Boniface Ⅷ declared that all pilgrims (朝圣者)travelling to Rome should keep to the left.This continued until the late 1700s when large wagons became popular for transporting goods. These wagons were drawn by several pairs of horses and had no driver’s seat. Instead, in order to control the horses, the driver sat on the horse at the back left, thus keeping his whip hand free. Sitting on the left however made it difficult to judge the traffic coming the other way, as anyone who has driven a left-hand drive car along the winding lanes of Britain will agree!In Britain there wasn’t much call tor these massive wagons and the smaller British vehicles had seats for the driver to sit on behind the horses. As most people are right-handed, the driver would sit to the right of the seat so his whip hand was free. Traffic congestion in 18th century London led to a law being passed to make all traffic on London Bridge keep to the left in order to reduce collisions. This rule was incorporated (并入) into the Highway Act of 1835 and was adopted throughout the British Empire.12．What probably happened in the Middle Ages?A．Passers-by walked on the right.B．Strangers fought every time they met.C．People would be attacked by strangers.D．Tourists travelled everywhere without limit. 13．What does the underlined word “sanctioned” in Paragraph 2 mean?A．Recognized.B．Designed.C．Explained.D．Postponed. 14．What was the attitude of drivers in the late 18th century to driving on the left?A．Unclear.B．Indifferent.C．Negative.D．Doubtful. 15．Which of the following can be the best title for the text?A．What Is the “Keep to the Left” Rule?B．Why Do the British Drive on the Left?C．Where Was “Drive on the Left” Carried Out?D．When Is the “Keep to the Left” Rule Popular?There are so many definitions of wisdom.
