鼻咽癌颈部转移性淋巴结的超声造影特征及时间强度曲线分析

Objective To study the character of cervical lymph nodes metastasis in nasopharyngeal carcinoma(NPC) by contrast-enhanced uhrasonography(CEUS) and time-intensity curve. Methods Forty-one lymph nodes of metastasis from 32 patients were studied by CEUS. The enhancement of echogenicity was evaluated,and the time-intensity curve was analyzed. Results Of the 41 lymph nodes examined, 10 (24.4%) showed intense homogeneous enhancement by CEUS, 23 (56.1%) showed inhomogeneous enhancement and 8 (19.5 %) showed scarce intranodal enhancement. There were 20 (48.8%) lymph nodes showed necrosis. Most of the lymph nodes (92.7%) showed peripheral type blood flow, 3 (7.3) % showed mixed type blood flow. There were significant differences in them(P < 0.01). The time-intensity curve displayed steeply in upslope, and gently in decent. The arrival time(AT), time to peak(TTP), peak intensity (PI) ,area and gradient were (7.2±2.5)s,(7.6±2.3)s,(9.5±3.3)dB,(203.4±45.7)dB· s,1.2±0.5 respectively. Between the lymph nodes with envelope infringed and not, there were significant differences in PI and area, while there were not significant differences in AT, TTP and gradient. Conclusions The metastasis cervical lymph nodes of NPC had specific character by CEUS and time-intensity curve. In this way,it may help us to diagnosis cervical lymph nodes metastasis of NPC,and provide more information for the therapy and prognosis judgement.     

第三腰椎与腰痛

第三腰椎与腰痛文／徐栋华脊柱作为人体的中轴，具有十分重要的运动功能。由于胸廓和骨盆相对固定，全身躯干的活动主要靠腰椎来完成，所以，自古以来即认为“腰乃一身之要”。用现代医学的解剖和生物力学知识进行研究，发现５个腰椎中又以第３腰椎最为重要，谓之“要中之...

甘甜的良药——蜂蜜

常言道“良药苦口利于病”,似乎好药总是味苦难以下咽。其实并不尽然。蜂蜜就是一种很有用处的“良药”,不但不苦,而且甘甜可口。 蜂蜜又称石蜜、蜂糖、食蜜。处方中又称蜜糖、白蜜、生蜜、炼蜜等。蜂蜜味甘,性平,入肺、脾、心、胃、大肠经。明代著名医学家李时珍在《本草纲目》中称它“生则性凉,故能清热,熟则性温,故能补中,甘而和平,故能解毒。柔而濡泽,故能润燥,缓可去急,故能止心腹肌肉疮疡之疼,和可致中,故能调和百药而与甘草同功。”

腕部骨折的家庭护理

腕部骨折的比例,在身体所有骨折中排在前列。受伤后手腕疼痛、肿胀,关节不能活动,发生畸形。一旦发生骨折,应尽早去医院检查、复位。复位后用石膏或夹板将手腕固定,维持位置,一般不须手术治疗,也不需住院。因此,自我照顾、家庭护理更显得重要。
