I am aware of 和製漢語, but I believe 和製漢字 is very rarely back-borrowed into Chinese.
In the case of 「氮」, the composition is 「气」 + abbreviated 「淡」, where 「淡」 is also the phonetic component, and is generally not used in Sino-xenic languages (in Japanese and Korean, nitrogen is called 「窒素」). From Wikipedia:
`中文名稱「氮」有沖淡氣體的意思。`

<p>We should first remember that「腺」's pronunciation derives from「泉」<em>in Japanese</em> (where both are pronounced <em>sen</em>), not <em>Chinese</em>. As far as I can find, Chinese sources never actually defined「腺」's pronunciation as being derived from「泉」<em>in Chinese</em>.</p>
<p>The source material from the Shen (2011) reference (<em>First report of the committee on medical terminology appointed by the China medical missionary association: Terms in anatomy, histology, physiology, pharmacology, pharmacy</em>) does not appear to be available on the web, but there is no explicit indication that they adopted the pronunciation 「泉」. This is what the reference actually says:</p>
<blockquote>
<p>The terminology committee thought that the translation term used in Japan for
“gland,” 腺, pronounced chuan in Chinese, could denote a “flesh spring,” and
thus the committee <strong>considered it an appropriate translation term</strong>.</p>
</blockquote>
<p>Or, in the Chinese reference (<a href="http://www.zjujournals.com/soc/CN/article/downloadArticleFile.do?attachType=PDF&amp;id=9324" rel="nofollow noreferrer">download link</a>):</p>
<blockquote>
<p>Gland 的译名，术语委员会认为来自日语的“腺”音 Chüuan，会意 flesh spring，<strong>是准确的</strong></p>
</blockquote>
<p>What's more, even though the committee report seems to have used the Romanisation <strong>Chüuan</strong>, the source material text smells more like an orthographic translation from Japanese.</p>
<blockquote>
<p><a href="https://i.sstatic.net/YQG38.jpg" rel="nofollow noreferrer"><img src="https://i.sstatic.net/YQG38.jpg" alt="enter image description here" /></a></p>
<p>Last part of the preface to the Japanese source text『西說醫範提綱釋義』by 宇田川 玄真 (<em>Udegawa Genshin</em>). The definition of「腺」is boxed in red:</p>
<blockquote>
<p>「腺」，新製字。音「泉」。</p>
</blockquote>
<p>Without paying attention to <em>Japanese sounds</em>, one might directly translate this as</p>
<blockquote>
<p>「腺」 <em>, newly coined character. Read as Chüuan.</em></p>
</blockquote>
<p>by transcribing「泉」into Chinese sounds, because the target language is, well, <em>Chinese</em>. But <em>First report of the committee on medical terminology</em> is an English text!</p>
</blockquote>
<hr />
<p>You may have a look at Chinese materials which explicitly define the pronunciations:</p>
<ul>
<li><p>「線」in <a href="http://www.guoxuedashi.com/kangxi/pic.php?f=zhdzd&amp;p=1633" rel="nofollow noreferrer">《中華大字典》</a></p>

</li>
<li><p>Or more rarely,「ㄒㄨㄢ」, which seemingly sounds closer to「泉」, but this is from the Taiwanese Hokkien dictionary 《彙音寶鑑》 (rather than the national language), and in Taiwanese Hokkien「線」may also contain an「ㄨ」(Hokkien, POJ: sòaⁿ / siàn).</p>

</ul>
<hr />
<p>My explicit take on the questions:</p>
<blockquote>
<p>Japanese seems to be the only language where the reading is consistent across all three characters. Why is this the case?</p>
</blockquote>
<p>This is because Japanese is rather phonologically poor; the distinctions made in the other languages have merged in Japanese.</p>
<blockquote>
<p>Is there a connection between 「腺」 and 「線」?</p>
</blockquote>
<p>Not in terms of <em>meaning</em>. The original logic behind choosing「線」for the reading of「腺」may be lost; all we know is that Chinese dictionaries have defined this reading early on, and some Chinese topolects may pronounce them similarly.</p>
<blockquote>
<p>Or was there simply an error when 「腺」 was introduced to China/Korea/Vietnam?</p>
</blockquote>
<p>I have a few speculations but no hard evidence:</p>
<ul>
<li>Chinese adopted an imitation of「せん」as the pronunciation of「腺」.「線」is not that far from「泉」in several topolects, so I doubt that it would have been seen as &quot;weird&quot;.
<ul>
<li>An early definition like 讀若線 in an authoritative dictionary like 《中華大字典》 has large implications on later dictionaries, and may have influenced Korean and Vietnamese adoption of the term.</li>
</ul>
</li>
<li>For Korean:
<ul>
<li>It may have adopted the Chinese definition (meaning &amp; sound) directly</li>
<li>Interestingly, the 訓讀 of「腺」(샘, <strong>saem</strong>, also the native word for <em>spring</em> as in <em>water source</em>) is coincidentally close to Japanese <strong>sen</strong> in initial and vowel</li>
</ul>
</li>
<li>Vietnamese may have adopted straight from Chinese (and please note, <strong>tuyến</strong> and <strong>tuyền</strong> only differ in tone; there is not as much discrepancy as in Mandarin)</li>

According to [Shen (2011)](http://www.sciea.org/data-j02/05_articles3_shen.pdf), it was the China Medical Missionary Association who adopted 腺 in Chinese in 1901, but _they_ used the pronunciation "chüan", which would correspond to modern "quán" like 泉 not 線.

That's interesting. I wonder then, how the pronounciation shifted from quán to xiàn, or if it was another source that popularized the usage of the character with the pronounciation xiàn in China. I'm also guessing that the term is first introduced in Mandarin, and then slowly propogates to other Chinese varieties.

Bar Japanese, in all of the Sinoxenic varieties, 線 sounds closer to Japanese せん than 泉. I'll bet that's the reason.

(Asked by: username_0 on 2019-07-03)

Quoting Wiktionary, the glyph origin of the character 「腺」 is as follows:

> A 国字 (kokuji, “Japanese-coined character”) coined in the late 1700s–early 1800s by rangaku scholar Udagawa Genshin as a translation for Dutch klier (“gland”), as an ideogrammic compound (會意): ⺼ (“flesh; body”) + 泉 (“spring; fountain; source; producer of liquid”), together expressing the idea “part of the body that produces liquid secretions”.

And the origin of its pronunciation is described like so:

> The reading sen is based on the kan'on of the 泉 base.

Which yields a 慣用音 of 「せん」(sen). However, it seems that other Sinitic and Sino-xenic languages' pronunciation of 「腺」 doesn't match with 「泉」, but rather 「線」. For comparison:

We should first remember that「腺」's pronunciation derives from「泉」*in Japanese* (where both are pronounced *sen*), not *Chinese*. As far as I can find, Chinese sources never actually defined「腺」's pronunciation as being derived from「泉」*in Chinese*.

The source material from the Shen (2011) reference (*First report of the committee on medical terminology appointed by the China medical missionary association: Terms in anatomy, histology, physiology, pharmacology, pharmacy*) does not appear to be available on the web, but there is no explicit indication that they adopted the pronunciation 「泉」. This is what the reference actually says:

Or, in the Chinese reference ([download link](http://www.zjujournals.com/soc/CN/article/downloadArticleFile.do?attachType=PDF&id=9324)):

> Gland 的译名，术语委员会认为来自日语的“腺”音 Chüuan，会意 flesh spring，**是准确的**

What's more, even though the committee report seems to have used the Romanisation **Chüuan**, the source material text smells more like an orthographic translation from Japanese.

泉 is pronounced as せん（sen） in Japanese. Many modern scientific terms were first translated into Japanese（in 19th centrury Japan was open to West World）, and then some Chinese scholars just borrow the term from Japanese Characters.

氮 may be another case, where 炎 is read as yan（3），but 氮 read as dan（4）。
