可益能与 肝病

治疗脂肪肝的合理性 抗病毒药物引起脂肪肝导致纤维化进而硬化 这个观察是从采用干扰素和病毒唑治疗丙型肝炎患者中获得 卡尼汀抗高血脂的作用是众所周知的 Romano 研究显示对丙型肝炎患者采用12个月卡尼汀和干扰素病毒唑联合使用,比单独使用干扰素和病毒唑有更好的抗高脂血的作用,肝的纤维化和硬化都被卡尼汀所降低 It is well described that in patients affected by Hepatitis C, the progressive deterioration of hepatic detoxifying functions and the persistent fatty degeneration lead to cirrhosis and to hyperammonemia, the leading cause hepatic encephalopathy. Whit regard to this often fatal event, interesting results have been obtained by Malaguarnera with L-Carnitine treatment on one hundred and fifty cirrhotic patients (10 with alcoholism, 41 HBV, 78 HCV, 21 cryptogenetic cirrhosis). Results showed that in all classes of Hepatic Encephalopathy graded patients, blood ammonia is significantly reduced by 3-months oral L-Carnitine treatment (4 g/d), and neuro-psychometric performance was significantly improved by L-Carnitine treatment. 在丙型肝炎病人中已经有了很好的描述,进行性肝解毒功能衰退和持久的脂肪变性导致肝硬化和血氨过多,导致肝性脑病。关于这个经常的致命事件, Malaguarnera给出了有趣的结果,可益能治疗150位肝硬化患者 (10个酒精肝、41 HBV,78 HCV,21 细胞生成的肝硬化)。结果表明,在所有类型的肝性脑病患者、血氨是显著减少通过3个月口服可益能治疗(4 g/d),神经心理测量的表现是由可益能治疗而显著提高。

治疗脂肪肝的合理性 Malaguarnera研究显示,没有酒精脂肪肝的患者显示,24周可益能的治疗降低了肝酶,使得血浆脂质变的正常,降低了血糖和胰岛素抵抗,降低了肝炎症和纤维化 Malaguarnera研究显示,可益能治疗显著降低了高血氨症,显著改善神经心理测量性能 It is well described that in patients affected by Hepatitis C, the progressive deterioration of hepatic detoxifying functions and the persistent fatty degeneration lead to cirrhosis and to hyperammonemia, the leading cause hepatic encephalopathy. Whit regard to this often fatal event, interesting results have been obtained by Malaguarnera with L-Carnitine treatment on one hundred and fifty cirrhotic patients (10 with alcoholism, 41 HBV, 78 HCV, 21 cryptogenetic cirrhosis). Results showed that in all classes of Hepatic Encephalopathy graded patients, blood ammonia is significantly reduced by 3-months oral L-Carnitine treatment (4 g/d), and neuro-psychometric performance was significantly improved by L-Carnitine treatment. 在丙型肝炎病人中已经有了很好的描述,进行性肝解毒功能衰退和持久的脂肪变性导致肝硬化和血氨过多,导致肝性脑病。关于这个经常的致命事件, Malaguarnera给出了有趣的结果,可益能治疗150位肝硬化患者 (10个酒精肝、41 HBV,78 HCV,21 细胞生成的肝硬化)。结果表明,在所有类型的肝性脑病患者、血氨是显著减少通过3个月口服可益能治疗(4 g/d),神经心理测量的表现是由可益能治疗而显著提高。

可益能在丙型肝炎中作用 结论: 慢性HCV患者,疲劳的严重程度和低的卡尼汀水平有关,建议口服卡尼汀会对 缓解HCV患者疲劳有效果 Anty R. et al. 发现血浆卡尼汀浓度与HCV的疲劳有关,但是与肠道易激综合症无关 结果: 慢性HCV和IBS患者的疲劳指数显著高于健康对比 与健康人相比,HCV患者有较低的调节脂肪量的血浆总卡尼汀和自由卡尼汀 慢性HCV患者的疲劳指数与血浆卡尼汀水平呈负相关 irritable bowel syndrome (IBS),肠道易激综合症 Patients with chronic hepatitis C had significant lower plasma levels of total and free carnitine adjusted for fat mass compared with healthy subjects. 与健康人相比,HCV患者有较低的调节脂肪量的血浆总卡尼汀和自由卡尼汀 In patients with chronic hepatitis C fatigue scores negatively correlated with carnitine plasma levels. 慢性HCV患者的疲劳指数与血浆卡尼汀水平呈负相关 Conclusions:In patients with chronic hepatitis C, the severity of fatigue is associated with a low level of carnitine, suggesting that an oral supplementation of L-carnitine may be effective to relieve fatigue in chronic hepatitis C. 结论:慢性HCV患者,疲劳的严重程度和低的卡尼汀水平有关,表明口服卡尼汀会对缓解HCV患者疲劳有效果 结论: 慢性HCV患者,疲劳的严重程度和低的卡尼汀水平有关,建议口服卡尼汀会对 缓解HCV患者疲劳有效果

可益能在丙型肝炎中作用 结果: 12个月可益能治疗显著降低了干扰素加病毒唑的高脂血症 可益能治疗降低了使用干扰素a和病毒唑治疗的慢性HCV患者的脂肪肝(肝细胞的脂肪变性/细胞中脂肪堆积产生脂肪滴) 研究评价了可益能治疗采用干扰素a和病毒唑治疗脂肪肝的患者的作用 采用剂量:12个月 剂量 2g/d 口服 患者: A组(35人):干扰素加病毒唑 B组(35人):干扰素加病毒唑加可益能 结果: 12个月可益能治疗显著降低了干扰素加病毒唑的高脂血症 接下来的6个月随访,组织学显示肝脏的纤维化和硬化显著降低 结论: 可益能能够预防使用干扰素和病毒唑治疗的HCV患者的脂肪肝 Romano et al - L-Carnitine Treatment Reduces Steatosis in Patients with Chronic Hepatitis C Treated with α-Interferon and Ribavirin 可益能治疗降低了使用干扰素a和病毒唑治疗的慢性HCV患者的脂肪肝(肝细胞的脂肪变性/细胞中脂肪堆积产生脂肪滴) Study evaluated the effect of L-Carnitine administration on steatosis in patients treated with Interferon- α and Ribavirin. 研究评价了可益能治疗采用干扰素a和病毒唑治疗脂肪肝的患者的作用 Dose used: 2 g/d os, 12-months 剂量 2g/d 口服 Results: After 12-months treatment with L-Carnitine significantly reduced the hyper-lipidemic effect of interferon plus Ribavirin 12个月可益能治疗显著降低了干扰素加病毒唑的高脂血症 After 6-months follow-up, hepatic fibrosis and steatosis, as histologically evidenced, is significantly reduced in patients treated with L-Carnitine. 接下来的6个月随访,组织学显示肝脏的纤维化和硬化显著降低 Conclusions: L-Carnitine treatment prevents liver steatosis in patients with hepatitis C treated with Interferon-α and Ribavirin. 可益能能够预防使用干扰素和病毒唑治疗的HCV患者的脂肪肝

可益能在非酒精脂肪肝中的作用 可益能补充到饮食中:一个新的治疗非酒精性脂肪肝的手段-一个随机对照研究 患者: A组 (n=36) :可益能2g/d,口服,24周,外加饮食 B组 (n=36) :安慰剂加饮食 结果:24周可益能治疗 • 降低了肝酶(转氨酶) • 使血脂正常 • 降低血糖水平和胰岛素抵抗 • 降低肝脏炎症和纤维化 所有的病人对可益能都耐受 结论:可益能治疗在治疗非酒精性脂肪肝中可成为一种有效的治疗选择 转氨酶是人体代谢过程中必不可少的“催化剂”,主要存在于肝细胞内。当肝细胞发生炎症、坏死、中毒等,造成肝细胞受损时,转氨酶便会释放到血液里,使血清转氨酶升高。 通常,体检中主要检查的转氨酶是谷丙转氨酶(ALT)。1%的肝脏细胞损害,可以使血中ALT的浓度增加1倍。因此,ALT水平可以比较敏感地监测到肝脏是否受到损害。 Malaguarnera et al - 2010 L -Carnitine Supplementation to Diet: A New Tool in Treatment of Nonalcoholic Steatohepatitis – A Randomized and Controlled Clinical Trial. 可益能补充到饮食中:一个新的治疗非酒精性脂肪肝的手段- 一个随机对照研究 结果:24-weeks L-carnitine treatment: 24周可益能治疗 • reduced liver enzymes; 降低了肝酶(转氨酶) • normalized plasma lipid profile; 使血脂正常 • decreased plasma glucose level and insulin resistance; 降低血糖水平和胰岛素抵抗 • decreased hepatic inflammation and fibrosis. 降低肝脏炎症和纤维化 L-carnitine treatment was well tolerated in 100 % of patients. 所有的病人对可益能都耐受 Conclusions L-carnitine treatment can represent a useful therapeutic options in NASH. 可益能治疗在治疗非酒精性脂肪肝中可成为一种有用的治疗选择

L-Carnitine in Hepatitis C 可益能在丙型肝炎中作用 Malaguarnera et al - 可益能在肝性脑病患者中的效果 研究评价了可益能对肝性脑病患者的精神状况和氨的作用的影响 使用剂量: 4 g/d 口服, 3个月 患者: 150 人 结果: 一个月可益能治疗( 4 g/d 口服)后,轻微肝性脑病和1级、2级肝性脑病患者的血清氨水平显著下降 2-3个月的治疗,可观察到持久的血清氨水平的降低趋势 可益能在精神功能评价的心理计量测试中也有显著治疗效果 结论: 可益能治疗对肝硬化病人的氨沉积引起的脑病具有保护作用 肝性脑病(hepatic encephalopathy, HE)是由于急、慢性肝病或各种原因的门-体分流(porto-systemicvenous shunting)所引起的,以代谢紊乱为基础的神经精神方面的异常。临床表现可以是仅仅用智力测验或电生理检测方法才能检测到的轻微异常,也可表现为行为异常、意识障碍,甚至昏迷。过去所称的肝性昏迷只是肝性脑病中程度严重的一期。仅用心理学检测方法才能检测到的轻微异常的肝性脑病又称为亚临床型肝性脑病(subclinical hepatic encephalopathy, SHE)或轻微肝性脑病(minimal hepatic encephalopathy, MHE) Malaguarnera et al - Effects of L-Carnitine in patients with hepatic encephalopathy 可益能在肝性脑病患者中的效果 Study evaluated the influence of L-Carnitine on mental conditions and ammonia effects on patients with hepatic encephalopathy (HE) 研究评价了可益能对肝性脑病患者的精神状况和氨的作用的影响;Dose used: 4 g/d os, 3-months 患者: 150 人 结果: After 1-months of L-Carnitine treatment (4 g/d, os) serum ammonia levels is significantly reduced in patients with Minimal Hepatic Encephalopathy, and in patients with Hepatic Encephalopathy grade 1 and grade 2 一个月可益能治疗后,轻微肝性脑病和1级、2级肝性脑病患者的血清氨水平显著下降 After 2-months and 3-months of treatment, a persistent trend of decreased ammonia serum levels is observed 2-3个月的治疗,可观察到持久的血清氨水平的降低趋势 A significant therapeutic effect of L-Carnitine was also observed in psychometric tests for the assessment of mental function 可益能在精神功能评价的心理计量测试中也有显著治疗效果 Conclusions: L-Carnitine treatment may have a protective effect against ammonia-precipitated encephalopathy in cirrhotic patients. 可益能治疗对在肝硬化病人的氨沉积引起的脑病具有保护作用

可益能:在丙戊酸诱导的肝中毒中的合理性 丙戊酸广泛用于治疗癫痫症并在肝脏线粒体中代谢 丙戊酸以丙戊酰卡尼汀的形式从肾脏清除 丙戊酰基对线粒体有毒,被卡尼汀清除,因此导致了卡尼汀存储的消耗 卡尼汀缺乏引起高血氨症并引起肝和脑功能紊乱并导致肝性脑病 补充卡尼汀恢复左卡尼汀的缺乏起到排毒作用从而恢复线粒体的性能 丙戊酸(Valproate)是治疗小儿癫痫常用药物之一。在使用中可发生两种类型的肝中毒。一种是与剂量有关的由于药物直接的损害,另一种是特发性原因不明的致死性损害。与剂量有关的肝中毒特点是在治疗的最初3个月期间,血清转氨酶(SGOT、SGPT)活性和血氨浓度短暂地升高,可占44%以上,常常没有症状,但亦可有恶心和萎靡,并不致死。另一类致死者与药物剂量无关而可能是由于特发性的反应,常是不可逆性损伤,肝功监测亦不易早期发现。至1982年为止。已知有62例因使用丙戊酸治疗而致肝中毒死亡。 Valproic Acid (VA) is widely used in epilepsy and is metabolized in the liver mitochondria. 丙戊酸广泛用于癫痫症并在肝脏线粒体中代谢 VA is eliminated by the kidney as Valproyl-carnitine. 丙戊酸以丙戊酰卡尼汀的形式从肾脏清除 Valproyl moyety is toxic for the mitochondria and is cleared by carnitine thus inducing a depletion of carnitine storage. 丙戊酰基对线粒体有毒,被卡尼汀清除,因此导致了卡尼汀存储的消耗 Carnitine deficiency induces hyperammonemia which is responsible for liver and brain dysfunction thus leading to hepatic encephalopathy.卡尼汀缺乏引起高血氨症并引起肝和脑功能紊乱并导致肝性脑病 Carnitine supplementation restoring the occurred depletion acts as a detoxifying agent thus restoring mitochondria performance. 补充卡尼汀恢复左卡尼汀的缺乏起到排毒作用从而恢复线粒体的性能 Valproate-induced hepatotoxicity (VHT) 丙戊酸诱导的肝中毒

L-Carnitine: Rational in Valproate-induced hepatotoxicity (VHT) 可益能:在丙戊酸诱导的肝中毒中的合理性 L-Carnitine: Rational in Valproate-induced hepatotoxicity (VHT) 实验和临床证据表明早期静脉滴注可益能可以改善严重丙戊酸中毒的生存率,推荐静脉而不是口服补充可益能是为了保证较高的血液中左卡尼汀的水平 尽管人的对照研究数量有限,对严重的丙戊酸引起的肝中毒的病例评估,较高的生存率的案例以及降低的高血氨症的报告,均来自使用可益能治疗的病人 Experimental and clinical evidence suggests that early L-carnitine i.v. administration improves hepatic survival in severe VHT. Intravenous rather than oral supplementation is recommended because it is likely to ensure higher blood levels of carnitine. 实验和临床证据表明早期静脉滴注可益能可以改善严重丙戊酸中毒的生存率,推荐静脉而不是口服补充可益能是为了保证较高的血液中左卡尼汀的水平 Although the limited number of human controlled studies, evaluating cases of severe hepatotoxicity occurring during VA therapy, higher survival cases and reduced hyperammonemia have been reported mainly in those patients treated with L-carnitine. 尽管人的对照研究数量有限,严重的丙戊酸引起的肝中毒的病例评估,较高的生存率的案例以及降低的高血氨症的报告,均来自使用可益能治疗的病人

可益能在丙戊酸肝中毒中的作用 患者: 92 有丙戊酸中毒导致的急性有症状肝功能衰竭的患者 结果: 静脉滴注可益能后,肝病患者生存者更加普遍 Bohan et al - 可益能治疗丙戊酸肝中毒的效果 研究评估了可益能治疗是否对患有急性严重有症状的丙戊酸中毒患者生存率有好的作用 使用剂量: 50-100 mg/d, os-iv, 一直用4个月 患者: 92 有丙戊酸中毒导致的急性有症状肝功能衰竭的患者 结果: 静脉滴注可益能后,肝病患者生存者更加普遍 在早期停用丙戊酸后(<5天),可益能的效果更加明显 结论: 对病毒酸诱导的肝中毒患者,可益能治疗与更高的生存率有关系 Bohan et al - Effect of L-Carnitine treatment for valproate-induced hepatotoxicity 可益能治疗丙戊酸肝中毒的效果 Study evaluated whether L-Carnitine treatment is associated with better hepatic survival of patients with acute, severe, symptomatic, valproate-induced hepatotoxicity 研究评估了可益能治疗是否对患有急性严重有症状的丙戊酸中毒患者生存率有好的作用 Dose used : 50-100 mg/d, os-iv, up to Patients: 92 patients with VPA-induced acute, symptomatic hepatic failure 92 有丙戊酸中毒导致的急性症状肝功能衰竭的患者 Results:Hepatic survival was much more prevalent after iv L-Carnitine treatment 静脉滴注可益能后,肝病患者生存者更加普遍 L-Carnitine effect was most apparent when VPA was stopped early (< 5 days) 在早期停用丙戊酸后,可益能的效果更加明显 Conclusions: In patients with Valproic Acid-induced hepatotoxicity, L-Carnitine treatment is associated with better survival 对病毒酸诱导的肝中毒患者,可益能治疗与更高的生存率有关系 4 months

可益能在丙戊酸肝中毒中的作用 Bohles et al 补充可益能对丙戊酸引起的高血氨症的作用 患者: 研究评价了补充可益能对丙戊酸治疗的病人的高血氨症的影响 采用剂量: 1 g/m2, os-iv, 一直用药 110 天 患者: 69个儿童和年轻人采用慢性丙戊酸单药治疗(15位患者采用可益能治疗) 结果: 丙戊酸诱导的高血氨症与降低的血浆卡尼汀水平有关 可益能治疗引起15.6%的血浆自由卡尼汀的增加 血氨与卡尼汀的水平显著相关 结论: 当血氨不正常升高时,应该推荐可益能治疗采用丙戊酸治疗的病人 Rational for L-carnitine in Valproate-induced hyperammonemia Carnitine supplementation (50 mg/kg per day) for 4 weeks was shown to correct both carnitine deficiency and hyperammonaemia in 14 VA-treated patients. Administration of exogenous carnitine is thought to decrease ammonia levels by binding to VA, thereby enhancing the β-oxidation process and production of acetyl-CoA, and relieving the inhibition of urea synthesis. 在14位丙戊酸治疗的病人中,补充可益能4周表现出纠正了左卡尼汀缺乏和高血氨症。外源左卡尼汀的给予被认识通过结合丙戊酸来降低血氨水平,因此加强了β氧化的进程和乙酰辅酶A的产生,并减轻了尿素合成的抑制。 Bohles investigated the effects of carnitine supplementation in 69 children and young adults treated with VA monotherapy. 研究了可益能补充给用丙戊酸单药治疗的69位儿童和青少年病人的作用 Their mean plasma ammonia concentration was within the normal range, but 24 patients (35.3%) with ammonia concentrations above 80 μg/dl were considered hyperammonaemic and 15 of these 24 (22.1%) had ammonia concentrations above 100 μg/dl. 他们平均血氨浓度在正常范围,但是24个病人的血氨浓度超过80微克/分升,被认为是高血氨,其中有15位血氨浓度超过100 Total plasma carnitine concentrations were determined in 48 out of 69 patients and were found to be rather low, as was the percentage of free carnitine. 69人中48人的确定了血浆卡尼汀浓度,结果发现非常低,像之前的自由卡尼汀。 Fourteen hyperammonaemic and one non ammonaemic patients were supplemented with L-carnitine (500 mg/m2, twice daily). Prolonged L-carnitine supplementation was associated with normalization in plasma ammonia concentrations and marked increase in carnitine concentration in all 15 patients. 14位高血氨症和一位非血氨患者给予可益能,在15为患者中,长期的可益能给予与血氨水平的正常化和左卡尼汀浓度的显著提高有关系 The plasma ammonia concentrations were significantly correlated with the percentage of free plasma carnitine in plasma (r = –0.67, P < 0.0001). These findings indicate that carnitine supplementation allows normalization of elevated plasma ammonia concentrations. However, a correlation between ammonia levels and clinical condition is not always observed. 血氨浓度显著地与自由卡尼汀在血浆中的百分比有关。这些发现表明补充可益能可以使增加的血氨浓度正常化。然而一直没有观察到血氨浓度和临床状况之间的关系。 L-carnitine dose used: Bohles: 1 g/m2, os-iv, up to 110 days 患者: 69 children and young adults under chronic Valproic Acid monotherapy (15 treated with L-Carnitine) 69个儿童和年轻人采用慢性丙戊酸单药治疗(15位患者采用可益能治疗) Results: Valproic Acid-induced hyperammonemia is associated with reduced plasma Carnitine levels 丙戊酸诱导的高血氨症与降低的血浆卡尼汀水平有关 Treatment with L-Carnitine led to median 15.6% increase in plasma free Carnitine 可益能治疗引起15.6%的血浆自由卡尼汀的增加 Plasma ammonia significantly correlated with Carnitine levels 血氨与卡尼汀的水平显著相关 Conclusions: L-Carnitine should be recommended in Valproic Acid-treated patients when plasma ammonia is inappropriately increased. 当血氨不正常增加时,可益能应该推荐治疗丙戊酸治疗的病人

可益能在丙戊酸肝中毒中的作用 Cuturic et al -有明确可益能缺乏症的住院精神病患者的临床结局和低剂量补充可益能:一个回顾性的图表总结 为了评价有明确低卡尼汀症的住院精神病患者可益能治疗的临床结局 患者:38为精神疾病患者 结果: 长期丙戊酸(血管纤维蛋白溶酶原激活剂)并不是单一的左卡尼汀缺乏的原因,29%的病人从没用过VPA治疗 明确左卡尼汀缺乏的病人,低剂量口服补充可益能与总体改善的行为、认知以及运动等有关系 在大多数病人中,细微神经检查获得改善和正常化,这纠正了最初被诊断给痴呆的病人的诊断 副作用较轻,不需要停止使用可益能的补充 结论: 通过补充可益能纠正左卡尼汀的消耗加强了低卡尼汀症的恢复,低卡尼汀症与精神病人的脑病有关 Rational for L-carnitine in Valproate-induced hyperammonemia Carnitine supplementation (50 mg/kg per day) for 4 weeks was shown to correct both carnitine deficiency and hyperammonaemia in 14 VA-treated patients. Administration of exogenous carnitine is thought to decrease ammonia levels by binding to VA, thereby enhancing the β-oxidation process and production of acetyl-CoA, and relieving the inhibition of urea synthesis. Bohles investigated the effects of carnitine supplementation in 69 children and young adults treated with VA monotherapy. Their mean plasma ammonia concentration was within the normal range, but 24 patients (35.3%) with ammonia concentrations above 80 μg/dl were considered hyperammonaemic and 15 of these 24 (22.1%) had ammonia concentrations above 100 μg/dl. Total plasma carnitine concentrations were determined in 48 out of 69 patients and were found to be rather low, as was the percentage of free carnitine. Fourteen hyperammonaemic and one non ammonaemic patients were supplemented with L-carnitine (500 mg/m2, twice daily). Prolonged L-carnitine supplementation was associated with normalization in plasma ammonia concentrations and marked increase in carnitine concentration in all 15 patients. The plasma ammonia concentrations were significantly correlated with the percentage of free plasma carnitine in plasma (r = –0.67, P < 0.0001). These findings indicate that carnitine supplementation allows normalization of elevated plasma ammonia concentrations. However, a correlation between ammonia levels and clinical condition is not always observed. L-carnitine dose used: Bohles:1 g/m2, os-iv, up to 110 days Cuturic et al - Clinical Outcomes and Low-Dose Levocarnitine Supplementation in Psychiatric Inpatients with Documented Hypocarnitinemia: A Retrospective Chart Review;有明确左卡尼汀缺乏症的住院精神病患者的临床结局和低剂量补充可益能:一个回顾性的图表总结 To evaluate the clinical outcomes in L-carnitine treated hospitalized psychiatric patients with documented hypocarnitinemia 为了评价有低卡尼汀症的住院精神病患者可益能治疗的临床结局 Results: Chronic VPA therapy did not appear as the sole cause of hypocarnitemia, as 29% of the patients had not been treated with VPA at any point 慢性丙戊酸(血管纤维蛋白溶酶原激活剂)并不是一个单一的左卡尼汀缺乏的原因,29%的病人从没用过VPA治疗 In patients with documented hypocarnitemia, a low-dose oral L-carnitine supplementation, was associated with overall improved behavioural, cognitive, and motor functioning 明确左卡尼汀缺乏的病人,低剂量口服补充可益能与总体改善的行为、认知以及运动等有关系 Mini-Mental State examination (MMSE) improved/normalize in most of the patients(mean improvement 5.5 points, p<0.0001). This allowed a correction of the diagnosis in some patients (8 of 14) who had initially been diagnosed with dementia 在大多数病人中,细微神经检查获得改善和正常化,这纠正了最初被诊断给痴呆的病人的诊断 Adverse effects were mild and did not require discontinuation of L-carnitine supplementation 副作用较轻,不需要停止使用可益能的补充 Conclusion: Correction of carnitine depletion by L-carnitine supplementation may enhance recovery from hypocarnitemia-associated encephalopathy in psychiatric patients 通过补充可益能纠正左卡尼汀的消耗加强了低卡尼汀症的恢复,低卡尼汀症与精神病人的脑病有关
