Core Viewpoint - The article discusses a groundbreaking study revealing a new physiological phenomenon where the central nervous system regulates intestinal nutrient absorption, particularly fat, through the vagus nerve, with implications for obesity and metabolic disease treatment [10]. Group 1: Research Findings - The study identifies that the Phox2b neurons in the dorsal motor nucleus of the vagus (DMV) can significantly influence fat absorption in the intestines, leading to weight loss in mice on a high-fat diet [7]. - The research team discovered that the herbal compound puerarin can reduce the activity of Phox2b DMV neurons, promoting fat excretion and aiding weight loss [8]. - The study confirmed that the GABRA1 protein, a subunit of the GABA A receptor, is a key target for puerarin, which enhances chloride ion influx and inhibits DMV neuron activity [9]. Group 2: Mechanism of Action - The research demonstrated that the inhibition of DMV neurons or intervention with puerarin leads to a significant reduction in the length of intestinal microvilli, which is crucial for fat absorption [9]. - The study utilized advanced techniques such as pharmacogenetics, neurophysiology, and structural biology to elucidate the molecular mechanisms by which puerarin exerts its effects [10]. Group 3: Implications for Future Research - The findings open new avenues for drug development targeting obesity and metabolic diseases by modulating the central regulation of intestinal fat absorption [10]. - The research highlights the potential for further exploration of the brain-gut signaling pathways, which could lead to innovative therapeutic strategies for managing obesity [10].

Core Viewpoint - The health issues faced by mathematician Wei Dongyi highlight the nutritional challenges faced by busy professionals, particularly entrepreneurs, emphasizing the importance of systematic health management in daily life [2][3]. Group 1: Health Challenges - Wei's health problems, particularly periodontitis, have drawn attention to the nutritional imbalances prevalent among busy individuals [3]. - His dietary habits reveal a preference for refined carbohydrates, with minimal intake of proteins, fruits, and vegetables, leading to potential nutritional deficiencies [4][5]. - The lack of essential nutrients, such as protein and vitamins, may contribute to his deteriorating health and increased risk of conditions like periodontitis [6][7][8]. Group 2: Nutritional Insights - Long-term nutritional deficiencies can accelerate aging and weaken the immune system, as seen in Wei's physical decline [11]. - A diet high in refined carbohydrates and low in proteins and fats can lead to poor skin health and emotional instability [12][13]. - Regular health check-ups may overlook early signs of nutritional deficiencies, which can have broader health implications [14][15]. Group 3: Recommendations for Entrepreneurs - Busy professionals should prioritize high-nutrition, low-calorie foods to combat the negative health impacts of fast-paced lifestyles [18][19]. - Carrying healthy snacks can provide quick nutrition and prevent reliance on unhealthy food options [24][25]. - Avoiding excessive reliance on takeout and refined carbohydrates is crucial for maintaining cognitive function and overall health [27][28][30]. Group 4: Emotional and Mental Health - Nutritional deficiencies can lead to emotional fluctuations, with specific vitamins and minerals playing key roles in mood regulation [33][34][35]. - Maintaining a balanced intake of fats, particularly Omega-3, is essential for mental health and emotional stability [36][37]. Group 5: Holistic Health Management - A balanced approach to eating, sleeping, and physical activity is vital for overall health [39]. - Regular sleep patterns and physical activity can significantly impact weight management and overall well-being [46][49]. - The importance of hydration and nutrient-dense foods cannot be overstated in maintaining energy levels and health [60].

Core Viewpoint - The first domestic Alzheimer's disease drug, Ganluotena Capsules (brand name: Jiuqi Yi), is facing a supply shortage due to production halts related to its registration certificate expiration, but the company, Shanghai Green Valley Pharmaceutical Technology, is in the final stages of approval and is optimistic about resuming supply soon [1][2]. Group 1: Product and Market Information - Ganluotena Capsules are priced over 1,000 yuan per box online, with a specification of 150mg and 42 capsules per box, requiring patients to take 6 capsules daily [1]. - The drug was conditionally approved by the National Medical Products Administration (NMPA) in November 2019 and was included in the medical insurance directory at the end of 2021, with the price reduced from 895 yuan to 296 yuan per box [1]. - Since its launch, over 500,000 patients have used Ganluotena, with sales exceeding 2.1 million boxes in 2024 alone [5]. Group 2: Regulatory and Production Status - The production halt is temporary and limited to the Ganluotena product line due to the need for a new registration certificate, with employees receiving minimum wage during this period [2]. - The company submitted supplementary applications for Ganluotena in May and October 2024, which will undergo comprehensive evaluation by the drug review center [3]. Group 3: Scientific and Clinical Background - Ganluotena is the world's first drug targeting the gut-brain axis for Alzheimer's disease, aiming to reshape gut microbiota, inhibit neuroinflammation, and improve cognitive function [4]. - The drug has faced controversy regarding its mechanism and the authenticity of research papers by its main inventor, but legal challenges against these criticisms have been dismissed [4].

Core Insights - The Chinese original drug "Jiuyiqi®" (Guanluo Sodium) has been discontinued after five years, marking a significant event in the Alzheimer's disease (AD) drug market [1][2] - Initially approved in November 2019, Jiuyiqi® was celebrated as the first targeted AD drug, but faced ongoing scrutiny regarding its safety and efficacy [1][2] Group 1: Drug Approval and Market Performance - Jiuyiqi® received "conditional approval" from the National Medical Products Administration, which required further submission of carcinogenicity test reports and long-term efficacy data [1] - The drug experienced a surge in demand upon its market entry and was included in the national medical insurance directory in 2021, expanding its market presence [2] - However, following the termination of international trials and internal team instability, sales declined sharply, leading to reports of stock shortages in pharmacies [2] Group 2: Controversies and Challenges - The drug's unique "gut-brain axis" mechanism faced strong criticism from the academic community, raising questions about its scientific validity [1] - Controversies arose from the clinical trial results, where the treatment group showed effects within four weeks, while the placebo group unexpectedly worsened, leading to debates over trial design [1] - The international Phase III trial, originally set to complete in 2025, was prematurely terminated in 2022, attributed to patient dropouts due to the pandemic and financing difficulties, which did not alleviate concerns over data reliability [1][2] Group 3: Regulatory and Industry Implications - The discontinuation of Jiuyiqi® serves as a warning for the Chinese innovative drug sector, highlighting the risks associated with "conditional approval" [2] - The situation raises questions about the regulatory environment and whether the approval process is becoming more stringent, as the company did not publicly address the reasons for the discontinuation [2] - The industry is urged to recognize that significant original mechanisms must withstand rigorous scrutiny from international peers, and academic criticism should be viewed as an opportunity to enhance research quality [2]
