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 recent incident of a man becoming paralyzed after improper cupping therapy highlights the risks associated with blind adherence to traditional Chinese medicine practices, particularly cupping, which is often misperceived as a universal remedy for various ailments [1] Summary by Sections Misconceptions about Cupping - Many individuals mistakenly believe that cupping can alleviate all types of discomfort, including headaches, insomnia, fatigue, and muscle soreness. However, cupping has specific indications and is primarily effective for conditions like wind-cold-damp obstruction, cough, chronic fatigue syndrome, and digestive issues [2] - Cupping is not suitable for certain conditions such as spasms, skin allergies, ulcers, edema, and areas with major blood vessels. Special caution is advised for individuals with weak constitutions, such as the elderly, children, and pregnant women [2] Location and Duration of Cupping - The common practice of cupping directly on the area of pain (e.g., "back pain, cup the back") is misleading. The selection of cupping sites should consider meridian pathways and the nature of the disease, rather than a simplistic approach [3] - Cupping duration should generally be limited to 5-15 minutes, depending on the patient's condition. Overextending the cupping time can lead to excessive local blood congestion and potential skin damage [4][5] Misinterpretations of Cupping Marks - The belief that deeper cupping marks indicate better detoxification is a misconception. The color of the marks reflects local blood circulation and the degree of capillary rupture, not the expulsion of toxins [7] - The assessment of treatment effectiveness should focus on symptom improvement rather than the appearance of cupping marks [7] Guidelines for Safe Cupping Practice - Proper cupping requires attention to detail, including the selection of appropriate cupping tools, maintaining a suitable environment, and ensuring patient comfort during the procedure [8] - Post-cupping care is crucial, as patients may experience redness or bruising, which is normal. However, precautions should be taken to avoid infection [9][10] - Cupping should be performed by trained professionals, especially for complex conditions, to minimize risks associated with improper techniques [10]
