[Objective]This study aimed to determine physiological and biochemical indices of Hailan chickens at 20 weeks of age.[Method]T,P,BT,CT,ESR,systolic pressure,diastolic pressure,RBC,HCT,MCV,RDW,HGB,MCH,MCHC,PLT,MPV,WBC,N,E,B,L,M,TP,Alb,AST,ALT,Glu and TG and CHO of 20 weeks-old male and female Hailan chickens were determined with various methods.[Result]According to the determined blood physiological and biochemical indices,RBC,HGB,Glu and ALB in male chickens were higher compared with female chickens,exhibiting extremely significant differences（P〈0.01）;B,M and TP in male chickens were significantly higher compared with female chickens（P〈0.05）;other physiological and biochemical indices exhibited no significant differences between males and females（P〉0.05）.[Conclusion]Physiological and biochemical indices of 20 weeks-old Hailan chickens varied between males and females,which were generally higher in male chickens than in female chickens.

Development of pore structures of activated carbon(AC)from activation of biomass with ZnCl_(2) relies on content and structure of cellulose/hemicellulose in the *** pretreatment of biomass could induce dehydration and/or aromatization to change the structure of cellulose/*** might interfere with evolution of structures of AC,which was investigated herein via thermal pretreatment of willow branch(WB)from 200 to 360℃and the subsequent activation with ZnCl_(2) at 550℃.The results showed that thermal pretreatment at 360℃(WB-360)could lead to substantial pyrolysis to form biochar,with a yield of 31.9%,accompanying with nearly complete destruction of cellulose crystals and remarkably enhanced aromatic ***,cellulose residual in WB-360 could still be activated to form AC-360 with specific surface area of 1837.9 m~2·g^(-1),which was lower than that in AC from activation of untreated WB(AC-blank,2077.8 m~2·g^(-1)).Nonetheless,the AC-200 from activation of WB-200 had more developed pores(2113.9 m~2·g^(-1))and superior capability for adsorption of phenol,due to increased permeability of ZnCl_(2) to the largely intact cellulose structure in *** thermal pretreatment did increase diameters of micropores of AC but reduced the overall yield of AC(26.8%for AC-blank versus 18.0%for AC-360),resulting from accelerated cracking but reduced intensity of ***-situ infrared characterization of the activation showed that ZnCl_(2) mainly catalyzed dehydration,dehydrogenation,condensation,and aromatization but not cracking,suppressing the formation of derivatives of cellulose and lignin in *** thermal pretreatment formed phenolic-OH and C=O with higher chemical innerness,which changed the reaction network in activation,shifting morphology of fibrous structures in AC-blank to“melting surface”in AC-200 or AC-280.

目的：研究不同强度的运动联合葛根素对非酒精性脂肪肝（NAFLD）大鼠模型的治疗作用和机制。方法：调节动物跑步机按照10、15、20 m/min 3种运动强度将大鼠分为低强度运动组、中等强度运动组和高强度运动组。运动组和治疗组中的大鼠均给予250 mg/kg葛根素日1次灌胃;除了对照组外,各组大鼠均给予高脂饲料喂养4周。在4周末,检测大鼠体质量和肝脏重量;检测血浆中透明质酸（HA）、层黏连蛋白（LN）、三型前胶原（PCⅢ）、四型胶原（Ⅳ-C）、丙氨酸转氨酶（ALT）、天门冬氨酸转氨酶（AST）;总胆固醇（TC）、甘油三酯（TG）、高密度脂蛋白（HDL-C）、低密度脂蛋白（LDL-C）、游离脂肪酸（FFA）和瘦素（Leptin）的浓度;检测肝脏组织中超氧化物歧化酶（SOD）和丙二醛（MDA）的含量;制作肝脏病理切片检测脂肪肝病变情况。结果：高脂饮食连续喂养4周能形成NAFLD大鼠模型。各运动组中体质量变化和肝脏指数均低于模型组（P〈0.05）;运动组和治疗组与模型组相比HA、LN、PCⅢ、Ⅳ-C、ALT和AST明显降低（P〈0.05）;运动组中和治疗组与模型组相比TC、TG、LDL-C、FFA和Leptin明显降低,而HDL-C明显升高（P〈0.05）;中等强度和高强度运动组中肝组织内无脂肪沉积。结论：葛根素可以降低血脂,改善肝脏功能,但不能减轻NAFLD程度;中等强度运动和高强度运动联合葛根素可以降低血脂、改善胰岛素抵抗症状、改善肝脏功能和防止NAFLD的发生。
