马尾松 马蹄莲 除了用马的身体部分命名外，马具也大量出现在命名中，这在其他生肖动物中是不多见的。最耳熟能详 的莫过于"马铃薯"，得名于块茎颜色和形态颇似古代使用的铜马铃。 "马兜铃"则是一种草质藤本植物，蒴果尚未成熟时垂挂，形似古代挂在马颈下的响铃。 马鞍作为重要的马具，也有以它为名的植物"马鞍藤"。它的正名叫作厚藤，其叶片厚实，近圆形，但先 端有一个明显的凹陷，有时甚至浅裂为两瓣，形状宛如马鞍。 还有大家熟悉的"马鞭草"，则得名于马鞭。其中，柳叶马鞭草被不少人熟知，它的顶端会形成分支的紫 色花序，成片种植时常被误认为薰衣草。 马年已至，不少市民的新春活动之一，就是到申城公园去赏马寻马。你知道植物世界里有哪些与"马"相 关的神奇植物吗？不妨听辰山植物园的专家来聊聊"马"是如何印刻到植物命名中的。 结构联想 辰山植物园博士郗旺介绍，将熟悉的动物身体结构和植物的形态进行类比和联系是一种古老而传统的植 物命名方式，马自然也不例外。 比如"马齿苋"，是一种匍匐生长、能开出黄色小花的植物。《本草纲目》中记载："其叶比并如马齿， 而性滑利似苋，故名。"马齿苋的种子细小，极易传播，是春季不容错过的美味野菜。 马飘逸的尾巴也 ...

Core Insights - The company, Qingyun Agricultural Technology Research Institute, has successfully developed a market for purslane, a vegetable with medicinal properties, which has not been widely cultivated in China [1][2] - The company plans to expand its production capacity and aims to become the largest purslane processing base in the country, targeting an annual output of 500 tons [3] Group 1: Company Operations - The company was founded in 2015, focusing on agricultural technology, and began working with purslane three years ago after identifying its potential in the local community [1] - The company has established a fully automated processing line for purslane, which includes cleaning, blanching, and drying, significantly reducing labor intensity [2] - In 2023, the company generated nearly 100,000 yuan from the sale of purslane-derived products, with expectations to double sales in the upcoming year [2] Group 2: Market Potential - Purslane can be harvested multiple times a year, with an average yield of 2,000 pounds per acre and a selling price of 0.8 yuan per pound, leading to an annual income of approximately 5,000 yuan per acre [2] - The local market has shown strong demand, with partnerships established with local restaurants and brands, indicating a growing interest in purslane products [3] - The company is actively promoting the cultivation of purslane among local farmers, which has led to increased interest and participation in the market [3]

Group 1 - Kidney stones are mineral deposits in the kidneys formed from crystals and organic matrix when certain minerals in urine become oversaturated, with calcium oxalate stones being the most common type [3][15] - Prevention of kidney stone recurrence requires intervention in daily diet and lifestyle, along with timely use of medications specific to the type of stones [3][15] Group 2 - Patients should limit high oxalate foods, which are significant contributors to calcium oxalate stone formation; common high oxalate foods include spinach, purslane, amaranth, beets, bamboo shoots, starfruit, sesame, and cocoa powder [5][17] - Cooking methods such as blanching can significantly reduce oxalate content; for example, blanching 180g of spinach in 1000ml of boiling water for 1 minute removes 43% of oxalate [6][19] - High purine foods like organ meats, seafood, and rich meat broths should also be limited as they can lead to uric acid stone formation [8][19] - High salt foods, including pickled products and processed meats, should be avoided as excessive sodium increases urinary calcium excretion, promoting kidney stone formation; the recommended daily salt intake for adults is no more than 5 grams [9][19] Group 3 - It is recommended for most kidney stone patients to drink 2.5 to 3.0 liters of fluid daily, ensuring a urine output of at least 2.0 to 2.5 liters [10][20] - Water is the preferred liquid, with moderate consumption of tea and coffee being acceptable; however, caffeine intake should not exceed 400mg, approximately equivalent to 2 cups of 355ml American coffee [12][22] - Adequate dietary calcium intake is essential to lower kidney stone risk, as calcium binds with oxalate in the digestive tract to form insoluble calcium oxalate, thus reducing the formation of calcium oxalate stones; the recommended daily calcium intake for adults in China is 800mg [12][22] - A balanced diet with sufficient vegetables and fruits is beneficial for alkalizing urine and providing citrate, although care should be taken with high oxalate fruits and vegetables [12][22]

Core Viewpoint - Excessive consumption of high oxalate foods like spinach can lead to secondary oxalate deposition nephropathy, with contributing factors including metabolic disorders and intestinal diseases [1] Group 1: Disease Mechanism and Types - Oxalate deposition nephropathy is characterized by the accumulation of oxalate crystals in the renal tubules and interstitium, resulting in kidney damage [2] - The disease can be classified into primary and secondary types, with secondary being more common and occurring at any age due to excessive oxalate intake and impaired excretion [2] Group 2: Dietary Factors and Risks - Foods high in oxalate include spinach, purslane, beet greens, nuts, chocolate, and tea, which can lead to the disease if consumed in excess [3] - Other factors such as excessive intake of oxalate precursors, dehydration, and lack of vitamin B6 can increase the risk of developing oxalate deposition nephropathy [3] Group 3: Prevention Strategies - Early detection of secondary oxalate deposition nephropathy can be achieved by testing urine oxalate levels, with a threshold of over 45 mg in 24 hours indicating high oxalate levels [4] - Prevention strategies include dietary modifications, such as reducing high oxalate food intake and ensuring adequate calcium and hydration to minimize oxalate absorption [5][6] - High-risk groups, including patients with chronic kidney disease and gastrointestinal disorders, should follow specific dietary guidelines and monitor their kidney function closely [6]

Core Viewpoint - The lesson delivered by Zhang Zhongde emphasizes the significant role of traditional Chinese medicine (TCM) during the Anti-Japanese War, highlighting its effectiveness in treating soldiers and the importance of passing down TCM wisdom to future generations [1][3]. Group 1: Role of Traditional Chinese Medicine - TCM played a crucial role during the Anti-Japanese War when Western medicine was scarce, utilizing local herbs such as mugwort, honeysuckle, and angelica to treat soldiers [1][3]. - Medical workers demonstrated resourcefulness by gathering herbs from the mountains and employing traditional methods to treat injuries and illnesses [2][3]. - The use of TCM for treating malaria and dysentery was validated through clinical trials, showcasing its effectiveness in wartime conditions [2][3]. Group 2: Cultural and Educational Significance - The lesson aims to instill a sense of patriotism and appreciation for traditional culture among students, linking physical health to the ability to contribute to the nation [4]. - The initiative reflects a broader educational goal of inspiring students to pursue careers in medicine, fostering a new generation of healthcare professionals [4].
