After operation , there were not significant changes of serum sexual hormones levels between JNA group and control group ( P > 0.05 ) .

鼻咽血管纤维瘤患者术后性激素水平与正常对照组水平变化不大（P>0.05）。

Objective : To investigate some clinical issues of transnasal endoscopic surgical procedure for juvenile nasopharyngeal angiofibroma ( JNA ) .

目的探讨鼻咽纤维血管瘤（JNA）鼻内镜下微创手术治疗的几个临床问题。

Methods : Congrated with literatures review , 4 cases with JNA who were treated with transnasal endoscopic surgical procedure were analyzed and summarized retrospectively .

方法结合文献复习，回顾性总结和分析4例JNA鼻内镜下微创手术治疗的，陆床资料。

Purpose : To further study the CT manifestations of juvenile nasopharyngeal angiofibroma ( JNA ) and its value in clinical diagnosis , treatment and evaluation of postoperative recurrence .

目的：进一步认识鼻咽纤维血管瘤的CT表现及其对于临床诊断、治疗和估计术后疗效的价值。

Materials and Method : 34 cases of JNA were retrospectively analyzed with their CT features , the accordance rate of CT diagnosis with clinical diagnosis and the recurrence rate of each stage ( Chandler ) .

材料和方法：回顾分析手术后病理证实34例鼻咽纤维血管瘤的CT表现、诊断与临床分期相符率以及Chandler各期的复发率。

Wayne Meissner , our native binding expert , worked extensively on JNA , and he carried that knowledge over to JFFI to make it faster more efficient .

我们的本地绑定专家WayneMeissner在JNA上做了大量工作，他将这些知识带到了JFFI上，让它更快更高效。

Conclusions JNA could significantly increase the expressions of ChAT and Syn protein in hippocampus of VD rats , it may be the mechanism of ameliorating the cognitive and memory impairment of dementia .

结论健脑安具有显著增加VD大鼠海马ChAT和Syn表达的作用，这可能是其改善痴呆认知和记忆障碍的作用机制。

Through the study for cytology of JnA , it was found that JnA aborted at last microspore-2-celled pollen stage and abortion was relative to abnormal split of tapetum .

细胞学观察发现，JnA的败育时期发生在单核晚期至二核花粉期，败育发生与绒毡层解体异常有关。

Before operation , the serum estrogen and progestin levels in JNA group were lower significantly than that in control group ( P < 0.05 ), and there was not significant change of serum testosterone level between two group ( P > 0.05 ) .

血清雌二醇、孕酮术前水平较正常对照组低（P<0.05），血清睾酮术前水平与正常对照组水平变化不大（P>0.05）；

Several sterile plants and half-restore plants were be found in F2 of JnA × Hui313 , which indicated that restoration of sterile character of JnA was controlled by main effect gene and micro-effect polygene .

从JnA×恢313的F2出现少量不育株和半恢株的情况看，JnA不育性的恢复既受主效基因控制，又受微效多基因控制。

The ChAT staining results showed that there were generous and orderly ChAT positive neuron in hippocampus of rats in JNA group and Duxil group , the ChAT positive staining in plasma was darker , and there were dense positive fibres .

ChAT免疫组化染色：健脑安组和都可喜组大鼠海马ChAT阳性神经细胞排列较规则，胞浆ChAT阳性染色较明显，可见阳性染色神经纤维，较密集。
