The past five years of Smokey's life have been unbearable. 过去五年的生活对于小猫Smokey而言十分难以忍受。
Her owner recalls when her once playful and curious kitty's behaviour changed. 她的主人回忆起这只曾经顽皮又好奇的小喵咪行为发生改变时的情景。
"Of 2011, I noticed that she started hiding and she wasn't as social “2001年的时候，我发现她开始躲起来，不再热衷于社交，
and then I noticed that her mouth was giving her problems." 随后我注意到这些问题的根源在于她的口腔。”
A trip to the vet confirmed that Smokey had FCGS, a painful inflammatory mouth disease. 看过兽医后，Smokey被证实患上了猫类慢性牙龈口腔炎， 这是一种疼痛的口腔炎症疾病。
"Chronic stomatitis is a common disease in the cat. It is very debilitating. “慢性口腔炎是一种猫类的常见疾病。这会使猫变得逐渐虚弱。
Those cats are in great pain. It is a very enigmatic disease because no one has been able to reproduce it in experimental cats." 这些猫处在极大的痛苦之中，而且这是一种很神秘的疾病， 因为没人能够在实验猫类身上使它重现。”
That's important because without being able to reproduce the disease in clinic, 这很重要，因为如果不能在临床上重复，
researchers have no idea what causes the disease or how to effectively treat it. 研究者们就不知道病因，亦不清楚如何有效地治疗这种疾病。
Cats with FCGS usually have all their teeth removed, 患有猫类慢性牙龈口腔炎的猫类通常会被拔去所有的牙齿，
clearing up the inflammation in some but not all cases. 这在部分但并非所有的情况下能够清除这些炎症。
Smokey wasn't lucky. Her teeth were extracted but the disease persisted. Smokey无疑是不幸的。她的牙齿已被拔出，然而疾病犹在。
That's when she was enrolled in a clinical trial of UC Davis. Researchers used cultured stem cells derived from 这时她已作为研究对象参与了加州大学戴维斯分校的一项临床试验中。 研究者试用的是人工培养的干细胞，
their feline patients in the hope of reducing inflammation and promoting tissue regeneration. 这些样本从希望减少炎症、促进组织再生的猫科患者中获得。
"I would say that most of our cats, if I have to give a number 60 to 70 percent have responded favorably to the treatment “我会说，我们大部分猫类样本，如果要给个数字的话， 60%-70%已对治疗顺利产生应答，
either by complete resolution or substantial clinical improvement without complete resolution at six months." 这个反应要么是炎症完全消退，要么是在炎症未完全消退的 六个月时的发生重要的临床改善。”
The researchers say these trials are shedding light on these types of inflammatory diseases 研究者们表示，临床实验正在阐明这些炎症疾病的前因后果，
and that could potentially have significant implications for humans. 而这在人类疾病治疗上也可能有着重要的应用前景。
"There are two other species that can get chronic inflammation of the mouth. “有两种其他物种也能产生慢性口腔炎症。
The first one is the dog and obviously we would like to look at treatment for dogs as well, 第一种是犬类，很明显，我们也希望研究犬类的治疗方案，
but even more importantly, humans also get inflammation of their oral cavity." 但更重要的是，人类也会患上口腔炎症。”
There are plans for human trials using stem cell therapy to treat inflammatory mouth disease as early as next year. 最早在明年，研究者将计划开展在人类身上使用干细胞疗法来治疗口腔炎。
As for Smokey, she's cured, but may need a diet. Her owner doesn't think so. 对于Smokey而言，她已被治愈了，但或许需要 控制饮食。她的主人却不这样认为。
"No. She has been through enough, whatever she wants she can have." “不。她已经受了这么多的苦，她想要的一切我都愿意给她。”
