目的观察皂术茵陈方治疗非酒精性脂肪性肝炎(non-alcoholic steatohepatitis,NASH)患者的临床疗效,并探讨其对游离脂肪酸(free fatty acid,FFA)及TNF-α的影响。方法采用随机数字表法将120例NASH患者分为治疗组及对照组,每组60例。治疗组予中药皂术茵陈方,每日1剂;对照组予水飞蓟宾葡甲胺片200 mg口服,每日3次,两组均治疗24周。分别于治疗前后通过检测血清ALT、AST活性及TC、TG水平;行腹部CT计算肝脾CT比值;应用肝组织病理检查评价非酒精性脂肪性肝病活动度积分(NAFLD activity score,NAS)及纤维化程度以评价临床疗效;并检测血清FFA及TNF-α含量。结果与本组治疗前比较,两组治疗后血清ALT、AST、TC、TG、FFA、TNF-α水平、肝组织NAS积分及症状体征积分均明显降低,肝纤维化程度明显改善(P<0.05,P<0.01),且治疗组降低更明显(P<0.05)。治疗24周后,治疗组肝纤维化分期总有效率及临床总有效率分别为80.00%(48/60)、85.00%(51/60),明显高于对照组[60.00%(36/60)、73.33%(44/60)],两组比较,差异有统计学意义(P<0.05,P<0.01)。结论皂术茵陈方可改善NASH患者的临床疗效,其作用可能与抑制血清FFA及TNF-α水平有关。Objective To observe the efficacy of Zaozhu Yinchen Recipe(ZZYCR) on non-alcoholic steatohepatitis(NASH) patients, and to explore its effect on serum free fatty acid(FFA) and tumor necrosis factor α(TNF-α).Methods Totally 120 patients with NASH were randomly assigned to the treatment group(60 cases,treated with ZZYCR, one dose per day) and the control group(60 cases, treated with Silibin Meglumine Tablets, 20 mg each time, thrice per day). The therapeutic course for all was 24 weeks. Serum levels of ALT and AST activities, TC and TG levels were detected before and after treatment. Peritoneal CT was performed in all patients, and CT ratios of liver and spleen calculated. NAFLD activity score(NAS) and degree of hepatic fibrosis were assessed using pathological examinations of liver tissue, and efficacy also evaluated. Serum contents of FFA and TNF-αwere also detected. Results Compared with before treatment in the same group, activities of ALT and AST, serum levels of TC, TG, FFA, and TNF-α, NAS, scores of symptoms and signs all obviously decreased, degree of hepatic fibrosis was obviously improved in the two groups(P < 0. 05, P < 0. 01). These changes were more obviously seen in the treatment group(P < 0. 05). After 24-week treatment, the total effective rate and total clinical efficacy were 80. 00%(48/60 cases) and 85. 00%(51/60 cases) in the treatment group, obviously higher than those in the control group [60. 00%(36/60 cases) and 73. 33%(44/60 cases) respectively], with significant difference(P < 0. 05, P < 0. 01). Conclusion ZZYCR could improve the clinical efficacy of NASH patients, and its mechanism might be associated with inhibiting serum levels of FFA and TNF-α.国家自然科学基金资助项目(No.81503529,81274155);; 福建省自然科学基金面上资助项目(No.2014J01374);; 福建省卫生厅中医药项目(No.wzpw201308);; 厦门市科技计划项目(No.3502Z20134020

Mechanism of geniposide in improving free fatty acid metabolism in rats with non-alcoholic fatty liver disease
观察栀子苷改善非酒精性脂肪性肝病的效果,从游离脂肪酸探讨栀子苷调节非酒精性脂肪性肝病的作用机制。健康雄性Wistar大鼠40只,随机分为4组:正常组、模型组、栀子苷组和血脂康组,每组大鼠10只,正常组大鼠给予正常大鼠饲料喂养,其余3组大鼠均采用高脂饲料喂养以诱导非酒精性脂肪性肝病,造模时间为8周,从第5周起至第8周末,栀子苷组和血脂康组分别灌服相应的药物。记录大鼠体重、肝湿重、脂肪质量;用相应方法检测肝组织TG,FFA,FAS,AMPK,ACCase及Malonyl-Co A含量,血清CHO,LDL-C的含量,血清AST,ALT的活性;观察肝脏组织肉眼及病理变化(HE染色法)。结果显示,与正常组相比,模型组大鼠的体重;肝湿重;脂肪重;血清CHO,LDL-C,ALT,AST;肝组织TG,FFA,FAS,ACCase及Malonyl-Co A含量皆显著升高(P<0.01);肝组织AMPK活性显著降低(P<0.01),肝组织肉眼外观及病理切片脂肪变性明显,并出现炎症损伤;与模型组相比,栀子苷组大鼠体重、脂肪质量、肝组织FFA含量、血清ALT,AST活性均显著降低(P<0.01),肝湿重,肝组织TG,FAS,ACCase及Malonyl-Co A含量明显降低(P<0.05),肝组织AMPK活性明显增多(P<0.05),肝脏肉眼外观及病理学表现均有所改善;与模型组相比,血脂康组大鼠的肝湿重、脂肪质量、肝组织TG,FFA和血清LDL-C水平明显降低(P<0.05);与血脂康组相比,栀子苷组大鼠的体重、脂肪质量、肝组织FFA含量均显著降低(P<0.01),其他方面无明显差异。结果表明,栀子苷具有显著的改善高脂饮食诱导的大鼠非酒精性脂肪性肝病的药理效应;其改善大鼠非酒精性脂肪性肝病的游离脂肪酸代谢是通过调节"AMPK-ACCase-Malonyl-Co A-FFA"轴来实现的。To observe the effect of geniposide on non-alcoholic fatty liver disease( NAFLD),and discuss the mechanism of geniposide for NAFLD from the aspect of free fatty acid,forty healthy Wistar male rats were randomly divided into normal group,model group,geniposide and Xuezhikang group. The rats in normal group were fed with normal diets,and the rats in other 3 groups were given with high-fat diet for 8 weeks to induce the NAFLD models. From the week 5 to end of week 8,the rats in geniposide and Xuezhikang group were intervened with corresponding medicines. The body weight,liver wet weight,and fat weight of the rats were recorded.Visual and pathological changes in hepatic tissues were observed with HE staining. The contents of TG,FFA,FAS,AMPK,ACCase and Malonyl-Co A in hepatic tissue,contents of CHO and LDL-C in serum and activities of AST and ALT in serum were detected by using corresponding methods. The results showed that the body weight,liver wet weight,and fat weight of the rats,CHO,LDL-C,ALT and AST levels in serum,TG,FFA,FAS,ACCase and Malonyl-Co A levels in hepatic tissues of the rats in model group were significantly higher than those in normal group( P < 0. 01),while AMPK activity was significantly lower than that of the normal group( P < 0. 01),with obvious visual and pathological steatosis in hepatic tissues,and inflammatory injury occurred in model group. Compared with the model group,body weight of the rat,fat weight,levels of FFA in hepatic tissues,ALT and AST activities in serum,liver wet weight,TG,FAS,ACCase and Malonyl-Co A levels were significantly decreased in geniposide group( P < 0. 01),while the AMPK activity in hepatic tissues was significantly increased( P < 0. 05),with improvement in visual and pathological performance.Compared with the model group,liver wet weight,fat weight,TG and FFA levels in hepatic tissues,and LDL-C level in serum were significantly decreased in Xuezhikang group( P < 0. 05). Compared with Xuezhikang group,the body weight of rat,fat weight and FFA level in hepatic tissues were significantly lower in geniposide group( P < 0. 01),but with no significant difference in other aspects. These findings indicated that geniposide was highly effective in improving the pharmacological effect of NAFLD induced by highfat diet,and the mechanism was achieved through AMPK-ACCase-Malonyl-Co A-FFA axis.国家自然科学基金项目(81274155;81503529);; 福建省自然科学基金项目(2014J01374);; 福建省高等学校新世纪人才计划项目;; 厦门市科技计划项目(3502Z20134020);; 福建省中医药科研项目(WZPW201308

Surface Disorder of GaN Irradiated by Highly Charged Arq+-Ions
Surface damage of gallium nitride films irradiated by Arq+ (6 ≤ q ≤ 16) ions at room temperature is studied by the atomic force microscopy. It is found that when charge state exceeds a threshold value, significant swelling was turned into obvious erosion in the irradiated region. The surface change of the irradiated region strongly depends on the charge state and ion fluence. On the other hand, surface change is less dependent on the kinetic energy nearly in the present experimental range (120 keV≤ Ek ≤ 220 keV). For q ≤ 14, surface of the irradiated region iscovered with an amorphous layer, rough and bulgy. A step-up appears between the irradiated and un-irradiated region. Moreover, the step height and the surface roughness are functions of the ion dose and charge state..
