Protective effect of gastrodin on bile duct ligation-induced hepatic fibrosis in rats

Gastrodin has been showed to possess many beneficial physiological functions, including protection against inflammation and oxidation and apoptosis. Studies showed inflammation and oxidation play important roles in producing liver damage and initiating hepatic fibrogenesis. However, it has not been reported whether gastrodin has a protective effect against hepatic fibrosis or not. This is first ever made attempts to test gastrodin against liver fibrosis in bile duct ligation (BDL) rats. The aim of the present study is to evaluate the effect of gastrodin on BDL-induced hepatic fibrosis in rats. BDL rats were divided into two groups, BDL alone group, and BDL-gastrodin group treated with gastrodin (5 mg/ml in drinking water). The effects of gastrodin on BDL-induced hepatic injury and fibrosis in rats were estimated by assessing serum, urine, bile and liver tissue biochemistry followed by liver histopathology (using hematoxylin & eosin and sirius red stain) and hydroxyproline content measurement. The results showed that gastrodin treatment significantly reduced collagen content, bile duct proliferation and parenchymal necrosis after BDL. The serum alanine aminotransferase (ALT) and serum aspartate aminotransferase (AST) decreased with gastrodin treatment by 15.1 and 23.6 percent respectively in comparison to BDL group did not receive gastrodin. Gastrodin also significantly increased the level of serum high density lipoprotein (HDL) by 62.5 percent and down-regulated the elevated urine total bilirubin (TBIL) by 56.5 percent, but had no effect on total bile acid (TBA) in serum, bile and liver tissues. The immunohistochemical assay showed gastrodin remarkably reduced the expressions of CD68 and NF-κB in BDL rats. Hepatic SOD levels, depressed by BDL, were also increased by gastrodin by 8.4 percent. In addition, the increases of hepatic MDA and NO levels in BDL rats were attenuated by gastrodin by 31.3 and 38.7 percent separately. Our results indicate that gastrodin significantly attenuated the severity of BDL-induced hepatic injury and fibrosis by attenuating oxidative stress and inflammation. Taken together, these findings suggest that gastrodin might be an effective antifibrotic drug in cholestatic liver disease.     

耳聋胶囊联合天麻素注射液治疗突发性耳聋的疗效观察

目的探究耳聋胶囊联合天麻素注射液治疗突发性耳聋的临床疗效。方法选取2016年1月—2017年1月陕西省核工业二一五医院耳鼻咽喉科收治的突发性耳聋患者161例为研究对象,所有患者随机分为对照组(80例)和治疗组(81例)。对照组肌内注射天麻素注射液,2 m L/次,1次/d。治疗组在对照组的基础上口服耳聋胶囊,3粒/次,2次/d。两组患者均治疗4周。观察两组的临床疗效,比较两组的言语频率平均听阈、症状消失时间和听力损失情况。结果治疗后,对照组和治疗组的总有效率分别为85.00%、97.53%,两组比较差异有统计学意义(P0.05)。治疗后,两组言语频率平均听阈均显著降低,同组治疗前后比较差异有统计学意义(P0.05);且治疗组言语频率平均听阈明显低于对照组,两组比较差异具有统计学意义(P0.05)。治疗后,治疗组呕吐、头晕、耳鸣消失时间明显短于对照组,两组比较差异有统计学意义(P0.05)。治疗后,两组轻度听力损失患者明显增加,中重度、重度和极重度患者明显降低,同组治疗前后比较差异有统计学意义(P0.05);且治疗组中重度、重度和极重度患者明显低于对照组,两组比较差异具有统计学意义(P0.05)。结论耳聋胶囊联合天麻素注射液治疗突发性耳聋具有显著的临床疗效,能够改善患者的听力损失程度,缩短临床症状消失时间,安全性较好,具有一定的临床推广应用价值。

Preparation and evaluation of sustained-release solid dispersions co-loading gastrodin with borneol as an oral brain-targeting enhancer

Borneol is a traditional Chinese medicine that can promote drug absorption from the gastrointestinal tract and distribution to the brain. However, stomach irritation may occur when high doses of borneol are used. In the present work, gastrodin, the main bioactive ingredient of the traditional Chinese drug “Tianma” (Rhizoma Gastrodiae) was used as a model drug to explore reasonable application of borneol. Sustained-release solid dispersions (SRSDs) for co-loading gastrodin and borneol were prepared using ethylcellulose as a sustained release matrix and hydroxy-propyl methylcellulose as a retarder. The dispersion state of drug within the SRSDs was analyzed by using scanning electron microscopy, differential scanning calorimetry, and powder X-ray diffractometry. The results indicated that both gastrodin and borneol were molecularly dispersed in an amorphous form. Assay of in vitro drug release demonstrated that the dissolution profiles of gastrodin and borneol from the SRSDs both fitted the Higuchi model. Subsequently, gastric mucosa irritation and the brain targeting of the SRSDs were evaluated. Compared with the free mixture of gastrodin and borneol, brain targeting of SRSDs was slightly weaker (brain targeting index: 1.83 vs. 2.09), but stomach irritation obviously reduced. Sustained-release technology can be used to reduce stomach irritation caused by borneol while preserving sufficient transport capacity for oral brain-targeting drug delivery.KEY WORDS: Borneol, Gastrodin, Oral drug delivery, Brain-targeting, Gastric mucosa irritation, Sustained-release
