腹部胀满。腰部软弱无力，感觉如同坐在水中一样。妇女小腹疼痛。有里急后重感及抽搐痉挛。月经不调。白带和赤色带下。左右环绕脐部、腰部和脊背疼痛，气冲心胸和腹部。
《内经》说：身体上半部分，由天气主导；身体下半部分，由地气主导。中间部位是天枢穴所在。天枢穴位于天地之气交汇的分界处。无论全身二十七经气的上下流行，都于此关卡锁住。而且必定有一种气来坚持并整束它，牢固地维持于上下之间。因此才能聚集成为强有力量的经脉。所以人的力量出于膂筋（背部肌肉），膂筋位于季胁之下，这正是带脉所在的位置。因此冲脉和任脉，传导至气街穴，即归属于带脉，并与督脉及太冲脉相联络。这些经脉之所以能上养心肺，也依赖于带脉的持束作用。
至于带脉发生病变，其症状都是向下而不向上的。这是因为下部肾肝虚弱，真阴不能滋养；上部心脾郁结，气机不能上下运行而停滞。于是湿气停留化为热邪，向下注入小肠和血海之间，疾病就发作了。所以赤白带下症，上部是因为心脾郁抑，下部是因为肾肝阴虚，邪热留恋不去，就成为带脉淫溢的疾病。腹部胀满，是因为中焦气机不运。腰部软弱无力如坐水中，是因为阴阳两虚，中焦虚弱而力量不足以镇定。左右环绕脐部、腰脊疼痛并冲犯心胸腹部，是因为阴气侵袭下部。阳气不能战胜阴气，也不能在天枢穴固守，因此阴气得以上侵，导致厥逆病症。大概约束关锁机关的关键，全在于带脉。如果带脉不能自我持守其气，其症状都会陷下而不能上升。治疗时有标和本之分。升降补泻的方法，在于探求根本原因进行治疗即可。
古人考察疾病的源头，推究疾病的起因，审察疾病的准确情况，没有超过《内经》的。后世医家务求支离破碎，所以模糊了疾病的由来，不能知晓阴阳脏腑的道理。现在汇集《内经》十六卷的文章，总结其中散见的论述，合并叙述为病情八章，使后学者能够明确指归。
Abdominal fullness. The waist feels weak and soft, as if sitting in water. In women, there is pain in the lower abdomen. There is a sensation of tenesmus (urgency with incomplete evacuation) and convulsions/spasms. Menstruation is irregular. Leukorrhea (white discharge) and metrorrhagia (blood-tinged discharge). Pain surrounds the umbilicus on both sides, extending to the lumbar spine, with Qi rushing to the heart and abdomen.
The *Neijing* states: The upper half of the body is governed by Heaven Qi; the lower half is governed by Earth Qi. The middle is the Tianshu point. Tianshu is located at the junction where Heaven and Earth Qi intersect. Regardless of the up-and-down circulation of the twenty-seven meridians throughout the body, they are locked at this pass. Furthermore, there must be a Qi that persists and binds them, firmly maintaining them between the upper and lower parts. Thus, it can gather to become strong and powerful. Therefore, human strength originates from the Lü muscle (back muscles), which is located below the costal margin. This is precisely the Dai Mai (Girdle Vessel). Thus, the Chong Mai (Penetrating Vessel) and Ren Mai (Conception Vessel) transmit to the Qicheng (Street of Qi) acupoint, thereby belonging to the Dai Mai, and connecting with the Du Mai (Governor Vessel) and Taichong Mai. The reason these vessels can nourish the Heart and Lungs upwards also relies on the holding function of the Dai Mai.
When the Dai Mai suffers disease, its symptoms are all downward rather than upward. This is due to deficiency of the Kidney and Liver in the lower part, causing True Yin not to nourish; and stagnation of the Heart and Spleen in the upper part, causing Qi to fail to circulate up and down. Consequently, Dampness stagnates and transforms into Heat, pouring downward into the Small Intestine and Blood Sea. Then the disease arises. Therefore, leukorrhea and blood-tinged discharge result from Heart and Spleen depression/stagnation above and Kidney and Liver Yin deficiency below, with pathogenic Heat lingering, becoming a disease of excessive discharge from the Dai Mai. Abdominal fullness is due to the failure of Middle Jiao Qi to move. The waist feeling weak and soft as if sitting in water is due to deficiency of both Yin and Yang, where the Middle Jiao is weak and lacks the power to stabilize. Pain surrounding the umbilicus and lumbar spine, rushing to the heart and abdomen, is due to Yin Qi invading the lower part. Yang Qi cannot overcome it nor guard the Tianshu point, so Yin Qi invades, leading to Jue-Ni (cold reversal) conditions. Essentially, the key to binding and locking the mechanisms lies entirely in the Dai Mai. If the Dai Mai cannot maintain its own Qi, its symptoms will all sink downward and fail to rise. Treatment has branch (biao) and root (ben) aspects. Methods of ascending/descending and tonifying/reducing lie in seeking the root cause to treat it.
In ancient times, examining the source of diseases, deducing their origins, and accurately assessing them, none surpassed the *Neijing*. Later generations pursued fragmented interpretations, thus obscuring their origins and failing to understand the principles of Yin-Yang and Zang-Fu organs. Now, collecting the texts from the sixteen volumes of the *Neijing*, summarizing scattered references, and combining them into eight chapters on disease conditions, so that later learners may find clear guidance.
