• 大鼠關(guān)節(jié)炎（CIA）造膜流程

  膠原誘導(dǎo)關(guān)節(jié)炎（CIA）S次應(yīng)用是用Ⅱ型膠原免疫Wistar(遠(yuǎn)親雜交)、Sprague-Dawley(遠(yuǎn)親雜交)和Wistar-Lewis(近交)中誘導(dǎo)成功。由于此CIA模型具有與人風(fēng)濕病關(guān)節(jié)炎（RA）相同的免疫和病理特征，因此該模型先后擴(kuò)展到小鼠及非人靈長類動物，并已作為人類關(guān)節(jié)炎研究的廣泛應(yīng)用的模型。然而，對于CIA模型來說，不同種屬動物之間是有差異的。小鼠對CIA的敏感性與主要組織相容性復(fù)合體（MHC）相關(guān)，在小鼠品系中只有DBA/1(H-2q)和B10.RⅢ(H-2r)兩個品系對CIA敏感。大鼠對CIA的敏感性也與MHC相關(guān)，并與小鼠相比具有較寬的品系范圍。因此，不同MHC型的不同品系的大鼠，盡管關(guān)節(jié)炎的發(fā)病率、嚴(yán)重程度及抗體和T-cell的特異性在不同品系間不同，但都能夠誘發(fā)關(guān)節(jié)炎。[詳細(xì)]

• 小鼠關(guān)節(jié)炎（CIA）造膜流程（Chondrex）

  膠原誘發(fā)的關(guān)節(jié)炎與人類風(fēng)濕病關(guān)節(jié)炎具有共同的免疫學(xué)和病理學(xué)特征，因此CIA模型被廣泛應(yīng)用于研究致病機(jī)理及ZL方法的研究。盡管關(guān)節(jié)炎模型是可復(fù)制的，但要成功誘導(dǎo)高發(fā)病率和嚴(yán)重程度的關(guān)節(jié)炎，一些影響造模因素需要考慮。以下是成功誘發(fā)小鼠關(guān)節(jié)炎的一些重要因素。在造模之前，特別是對于S次造模者，這些因素需要提前考慮到。然而，正如其它生物模型，不同研究單位的方案有所不同，因此，每個研究者需要確定自己的研究方案。[詳細(xì)]

• 富氫水對關(guān)節(jié)炎的功效

  富氫水對關(guān)節(jié)炎LX的研究我本人10年前就有單側(cè)膝關(guān)節(jié)炎，Z明顯的感覺就是天氣潮濕會加重，因?yàn)椴⒉皇謬?yán)重也沒有過多關(guān)注。2008年開始我經(jīng)常飲用氫水，就在飲用氫水2個月的時(shí)候，我就驚奇地發(fā)現(xiàn)自己關(guān)節(jié)炎似乎痊愈了，但個人情況不能完全說明問題，后來我們在我校解剖教研室開展的氫水ZL關(guān)節(jié)炎的研究中，證明氫水對動物關(guān)節(jié)炎能快速有效ZL，再后來日本學(xué)者也發(fā)表氫水對人類類風(fēng)濕關(guān)節(jié)炎治LX果的研究，雖然研究規(guī)模比較小，但提示骨關(guān)節(jié)炎是氫氣ZL的重要疾病類型，因?yàn)殛P(guān)節(jié)炎發(fā)病率非常高，給患者生活帶來很多不良影響，氫氣對關(guān)節(jié)炎的ZL研究值得深入開展，尤其是臨床對照研究。骨性關(guān)節(jié)炎是Z常見的一種關(guān)節(jié)疾病，嚴(yán)重威脅著人類的健康與生活，隨著老齡化社會到來，其發(fā)病率逐年增加。骨性關(guān)節(jié)炎是一種慢性、進(jìn)展性關(guān)節(jié)疾病，以關(guān)節(jié)軟骨變性和丟失及關(guān)節(jié)邊緣和軟骨下骨骨質(zhì)再生為特征的慢性關(guān)節(jié)炎疾病。目前藥物ZL該病效果差，各種外科ZL如清創(chuàng)、鉆孔減壓、骨軟骨移植、骨膜移植等，雖能暫時(shí)緩解疼痛但Z終會失敗。因此尋找一種新的ZL方法迫在眉睫。研究目的：通過動物實(shí)驗(yàn)分析富氫生理鹽水腹腔注射，ZL大白兔創(chuàng)傷性骨關(guān)節(jié)炎的可行性及安全性，并探討其對創(chuàng)傷性骨關(guān)節(jié)炎的恢復(fù)的影響，為臨床上同類疾病ZL提供實(shí)驗(yàn)依據(jù)。研究方法：新西蘭大白兔30只，隨機(jī)分為三組：正常對照組10只，生理鹽水組10只，富氫生理鹽水組10只。生理鹽水組和富氫生理鹽水組20只家兔均行手術(shù)制作膝骨性關(guān)節(jié)炎模型。富氫生理鹽水組：腹腔注射富氫生理鹽水lOml／kg，每3天1次，生理鹽水組：腹腔注射等量生理鹽水，正常對照組不給藥，ZL持續(xù)6周。于ZL前后分別取3組家兔血清及關(guān)節(jié)液測定白細(xì)胞介素-1(IL-1)、腫瘤壞死因子(TNF)的含量，結(jié)合家兔的行為學(xué)表現(xiàn)對治LX果進(jìn)行評價(jià)。研究結(jié)果：①行為學(xué)改變上富氫生理鹽水組ZL后有明顯改善(P<0.05)。②膝關(guān)節(jié)腫脹評分ZL前兩模型組無差異(P>0.05)，ZL后富氫生理鹽水組優(yōu)于生理鹽水組(P<0.05)。③ZL前兩個模型組血清及關(guān)節(jié)液中IL-1、TNF含量升高有統(tǒng)計(jì)學(xué)意義(P<0.05)，ZL后富氫生理鹽水組均明顯下降(P<005)，生理鹽水組無明顯變化(P>0.05)。④造模8周后，關(guān)節(jié)內(nèi)有渾濁的滑液，股骨髁處可見軟骨表面有重度裂紋及潰瘍形成，軟骨剝脫，達(dá)骨質(zhì)，可見軟骨下骨，有骨贅形成。HE染色可見骨組織，軟骨細(xì)胞較少。研究結(jié)論：腹腔注射富氫生理鹽水ZL兔骨性關(guān)節(jié)炎有一定的LX，將為膝關(guān)節(jié)損傷軟骨修復(fù)ZL提供一個新思路。選摘《氫思語》[詳細(xì)]
