Some vasovagal syncope (WS) patients developed tachycardia during the head-up tilt test (HUTT), of which bradycardia is the most common. There are different in shape of ECG waves between HUTT negative patients and HUTT positive patients.The dysfunction of autonomic nerve system could be the main reason.It could be helpful in diagnosis and treatment of VVS to leant the ECG change and its predictive value of HUTT result, effect of treatment and prognosis.

Language learning strategy is one of the most important items in current college English syllabus,yet it hasn't been given enough attention to.Due to the features of medicine,it is of great importance and emergency to carry out language learning strategy training in medical colleges.The aim of this essay is to promote a new English teaching mode of strategy-based instruction.

Brain metastasis is a common and devastating consequence of disease progression in patients with lung cancer.Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKI) may enhance radiosensitivity by reducing the cells in S phase,reducing angiogenesis of tumor cells,increasing irradiation apoptosis,inhibiting tumor cells proliferation by fractionated irradiation and reducing radiotherapy resistance.The clinical results of radiotherapy combined with EGFR-TKI (such as gefitinib) in treatment of brain metastasis from lung cancer showed higher response rate and longer survival.The toxicities during EGFR-TKI treatments were low,and could be controllable after symptomatic treatment.Administration of EGFR-TKI combined radiotherapy conferred minimum influence on radiotherapy.

Objective To study the 5 years contraceptive efficacy of levonorgestrel intrauterine system (LNG-IUS) and the ovarian functions in amenorrhea women. Methods LNG-IUS and TCu 380A IUD were randomly inserted in 2 groups of women, 50 each. Women were followed annually for 5 years. Serum follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), estradiol (E 2), and T levels in 14 women with amenorrhea, and endometrial biopsies were obtained in 9 cases. Results By the end of 5 years, there were 2 pregnancies in TCu 380A group, but none in LNG-IUS group; and 24 amenorrhea cases in LNG-IUS. The 5 year cumulative continuation rates were 24% for LNG-IUS and 78% for TCu 380A ( P

Eighty percent of unexplained syncope children can be diagnosed of vasovagal syncope (VVS). Positive head-up tilt test (HUTT) leads to the diagnosis of VVS. However,organical diseases which can cause syncope should be excluded before HUTT was taken. The therapies of VVS include nonpharmacological therapy (health education, head-up training, water and salt supplement), pharmacological therapy (β-blockers, α-receptor agonists, fludrocortisone, selective serotonin reuptake inhibitors, angiotension converting enzyme inhibitors, et al.) and pace maker.
