注：本经的解析中，从肺俞穴开始一直至白环俞穴共十八穴，解析的内容都只是言及各穴内部外输膀胱经的气血物质和运行规律，并没有涉及到经脉中上下穴位间相互传递的气血物质。而实际上，自心俞穴开始，穴内就有地部的经水流行，且至白环俞穴后地部的经水达到了最大量。首先是肺俞穴外传膀胱经的气血为湿热之气，其湿热之气一方面受厥阴俞、心俞、督俞等穴外传的高温热气作用而胀散化风上传风门穴，另一方面，气血中富含的较多水湿又会对厥阴俞、心俞、督俞等穴外传的高热之气起降温作用。因此，厥阴俞、心俞、督俞等穴外传的气血物质在和经脉中流行的气血物质相合后，以上几穴中的气血物质和其外传的气血物质相比温度就有了降低，此为其一。其二是心俞穴外传的高温高热之气，其气中水湿浓度大，受膀胱经经脉中流行的气血影响，小部分水湿会冷降归地，因此，自心俞穴开始，膀胱经的心俞穴下段经脉中就有了地部经水。其三是自膈俞穴开始至白环俞穴的以下各穴，它们由内外传的水湿之气都会因膀胱经的寒冷特性而部分冷降归地并汇入地部流行的经水之中，因此，膀胱经背部经脉各穴中流行的经水在白环俞穴达到最大。本经穴解析中没有把脏腑外输的气血与经脉中流行的气血结合起来一起分析，原因在于一是有相当的难度，二是不能更好地说明各穴对其所属脏腑的调节作用，故没有结合在一起分析。

Aliases: Jueshu, Xinbaoshu, Guanshu.
Acupoint meaning: The yang-heat qi from the Pericardium, which guards the exterior of the Heart Chamber, is transmitted here into the Bladder Meridian.
Name explanation:
1) Jueyinshu. "Jue" (Jue) is interchangeable with "Que" (Que), referring to the defensive structures of ancient palaces or tombs. In the context of the Jueyin Meridian, it indicates that the qi and blood of the Jueyin Meridian are the qi-transformed essence of Heart Blood. The name Jueyinshu implies that the dry-hot qi from the Pericardium guarding the Heart Chamber is externally transmitted to the Bladder Meridian through this point. The names Jueshu and Xinbaoshu share the same meaning as Jueyinshu.

Qi and Blood characteristics: The substance consists of yang-heat qi at a relatively high temperature, rich in dampness.
Running pattern: Transmitted externally from the Pericardium guarding the Heart Chamber to the Bladder Meridian.

2) Beishu. "Bei" refers to the back, indicating the location of the acupoint. "Shu" means transmission. The name Beishu implies that high-temperature damp-heat qi from the Heart Chamber is externally transmitted to the back through this point.
Qi and Blood characteristics: The substance is high-temperature damp-watery qi.
Running pattern: The damp-watery qi dissipates heat and transmits upward along the Bladder Meridian; meanwhile, after the water-dampness dissipates heat and cools downward, it flows downward along the Bladder Meridian.
Function: Dissipates heat from the Heart Chamber.
Treatment method: For cold patterns, apply tonification and moxibustion, or use aquapuncture; for heat patterns, apply sedation to release pathogenic qi or use aquapuncture.

Note: In the analysis of this meridian, from Feishu (BL-13) to Baihuan shu (BL-30), totaling eighteen acupoints, the analysis only discusses the qi and blood substances transmitted externally to the Bladder Meridian from within each point and their running patterns, without involving the mutual transmission of qi and blood substances between upper and lower acupoints in the meridian. In reality, starting from Xinshu (BL-15), there is the flow of Jing Water (meridian water) at the Earth Level within the acupoints, reaching its maximum volume at Baihuan shu (BL-30). First, the qi and blood transmitted externally from Feishu (BL-13) to the Bladder Meridian is damp-heat qi. On one hand, this damp-heat qi expands and transforms into wind under the influence of the high-temperature heat qi transmitted externally from Jueyinshu (BL-25), Xinshu (BL-15), and Dushu (BL-16), transmitting upward to Fengmen (BL-12); on the other hand, the abundant water-dampness in the qi and blood cools down the high-heat qi transmitted externally from Jueyinshu, Xinshu, and Dushu. Therefore, when the qi and blood substances transmitted externally from Jueyinshu, Xinshu, and Dushu combine with the flowing qi and blood in the meridian, the temperature of the qi and blood in these points becomes lower compared to their externally transmitted substances; this is the first reason. Second, the high-temperature, high-heat qi transmitted externally from Xinshu (BL-15) has a high concentration of water-dampness. Influenced by the flowing qi and blood in the Bladder Meridian, a small portion of water-dampness cools and descends to the Earth Level. Thus, starting from Xinshu (BL-15), Jing Water at the Earth Level exists in the lower segment of the Bladder Meridian below Xinshu. Third, from Geshu (BL-17) to Baihuan shu (BL-30), the watery qi transmitted from both internal and external sources partially cools and descends to the Earth Level due to the cold nature of the Bladder Meridian, merging into the flowing Jing Water at the Earth Level. Consequently, the flowing Jing Water in the back meridian acupoints of the Bladder Meridian reaches its maximum at Baihuan shu (BL-30). The analysis of these acupoints does not combine the qi and blood transmitted externally from the Zang-Fu organs with the flowing qi and blood in the meridian because doing so is quite difficult and does not better explain the regulatory function of each point on its corresponding Zang-Fu organ. Therefore, they are not analyzed together.
