（二）从以下两个方面看肾虚在哮喘中的重要性进一步有所提高：
(Ⅱ) The increasing importance of Kidney deficiency in the treatment of asthma could be seen in the two aspects below:

1．宿根从肾虚解释增加：
1. The explanation of Sugen from kidney deficiency was increased:

王志英等认为，“宿根”主要指宿痰内伏。然《景岳全书?痰饮》云：“五脏之病，虽俱能生痰，然无不由于脾肾，盖脾主湿，湿动则为痰；肾主水，水泛亦为痰，故痰之化无不在脾，而痰之本无不在肾”。因此，咳喘其根本在肾，从补肾入手防治哮喘的看法为古今医家所肯定。
Wangzhiying thought that, "Sugen" was mainly indicated the stayed sputum in the body.But the book <Jingyuequanshu?phlem and sputum> said that: ’though not all the disease of the five orgons formed sputum, but all of disease arised form the spleen and kidney, because the spleen governed the wetness, the moving of wetness was sputum；kidney governed the water, the flooding of water was sputum, so the forming of sputum was accounting for the spleen，and the root of sputum were all in kidney’. So the fundamental reason of asthma was kidney, treating and preventing the asthma form the invigorating the kidney was affirmed by the doctors of the anciently and today.

张智娟等总结有的学者提出：哮喘的宿根与气道的高反应性有关，认为肾亏为哮喘病的宿根，从而揭示了肾虚与哮喘的现代联系。
Zhang Zhijuan and others referred that the Sugen of asthma related to the hyperactivity of airway and the kidney deficiency was the Sugen wo asthma, so revealed the modern relation between kidney deficiency and asthma.

柯新桥认为支气管哮喘宿痰停伏是急发期的基本病因，然宿痰内伏与病者先天禀赋不足、肾阳气亏密切相关。
Ke Xinqiao thought that stayed sputum of bronchial asthma was the basic reason of the acute stag, but the stayed sputum stopped in the body had close relationship with the o with congenital inadequate and Kidney-Yang-Qi deficiency of patients.

华译网北京翻译公司翻译过大量有关肾虚在哮喘中的重要性的文件资料,Beijing Chinese Translation Service Company has translated many technical documents about importance of Kidney deficiency in the treatment of asthma

刘仁慧等认为哮喘的病理产物主要为痰，痰的产生除与肺有关外，与脾肾的关系更为密切。明代医家王节斋云：“痰之本，水也，原动于肾；痰之动，湿也，主于脾。”现已有人提出哮喘的“夙根”当指患者的禀赋素质而言，与现代医学所称的“特异性体质”相类似。其实质主要是指脏腑阴阳失调，肺脾肾对津液的运化失常。指出肺脾肾虚为夙根，强调体质因素的重要意义。有人强调肾虚是哮喘患者的基本体质，无论临床有无肾虚之证，皆存在“隐潜性肾虚证”，主张发作期、缓解期均应补肾治疗。
Liu Huiren thought that the physical product of the asthma was sputum, the formation of sputum had relation to the lung, except that, the spleen was closely related. The doctor of Ming Dynasty Wang Zhaiyun said: ’The root of sputum was water，pushed by kidney; The moving of sputum was wetness, governed by spleen ” Now, there were someone pointed out that the Sugen of asthma was the quality of patient temperament, which was similar with ‘specific body’ of modern medicine. Its essence mainly was the imbalance of the viscera and yin-yang, the dysfunction of lung ,spleen and kidney that the transportation and transform of fluid. Figured that the deficiency of lung, spleen and kidney was Sugen, emphasized the importance of corporeity.Somebody emphasized kidney deficiency is the basic corporciency of asthma patients, it all had ‘potential kidney deficiency’ no matter whether there was symptom of kidney deficiency, and advocated the invigorating kidney at attack and remission stage.

石亚杰等认为痰的根本在肾。《景岳全书?论痰之本》曰：“夫痰即水也，其本在肾，……在肾者以水不归原，水泛为痰也，故治痰者，必当温脾强肾，以治痰之本，使根本渐充，则痰将不治而自去矣。”《医学集成?痰证》曰：“痰虽生于脾胃，其实由肾阳虚损，不能熏蒸脾胃，以致脾不纳涎而痰成矣。”
Shi Yajie felt that the root of sputum in the kidney<Jing Yue Quanshu ? On the sputum> said: " sputum was water, its root was in the kidney, ... the water in the kidney did not go back to the original place and flooding to form sputum, Therefore the basic way of treating sputum was invigorating the kidney softly, and made the root gradually permeated, so the sputum disappeared without treatment. <Integrated Medince?sputum> said : "Although sputum was formed in spleen and stomach, but actually, the reason was that Yang deficiency of kidney could not warming the spleen and stomach and made the spleen and stomach couldn’t absorb the saliva and resulted the formation of sputum.
