高原康胶囊对大批快速进入高原者血浆醛固酮、血管紧张素II及水负荷的影响及意义

目的 :了解高原康胶囊对快速进入高原者血浆醛固酮 (Aldosterone ,ALD)、血管紧张素II(AngiotensinII ,AII)及水负荷的影响及意义。方法 :将 80名由平原快速进入高原的新兵随机分为实验组 4 0名 ,对照组 4 0名 ,实验组于平原登机前开始给予口服高原康胶囊 ,连服 3日 ,对照组给予安慰剂 ,两组均于进入高原的前 1天及进入高原的第 3天午给予水负荷实验 ,并对饮水前血浆ALD、AII及饮水后 15 0min内各时间段的尿量及两组进入高原后 7天内急性高原病 (Acutehighal titudediseaes ,AHAD)的发病率进行对照比较。结果 :对照组进入高原后与平原相比血浆ALD、AII显著升高 ,水负荷实验 6 1min～ 15 0min各时间段的尿量及相应时间的总尿量与平原时相应各时间段的尿量及相应时间的总尿量相比则显著减少 (P <0 0 5～ 0 0 0 1) ,而实验组则无显著变化 (P >0 0 5 ) ;进入高原后实验组与对照组相比水负荷实验 6 1min～ 90min的尿量及 12 0min、15 0min的尿总量则显著多于对照组 (P <0 0 5 ) ;血浆ALD、AII及AHAD发病率则显著低于对照组 (P <0 0 5～ 0 0 0 1)。结论 :高原康胶囊能显著降低快速进入高原者的血浆ALD、AII ,通过对水负荷调节的影响减少机体的钠水潴留 ,从而防止快速进入高原者AHAD的发生 ,可用于大批快     

PRENATAL DIAGNOSIS Ⅰ. EARLY DIAGNOSIS OF OPEN NEURAL TUBE DEFECTS BY QUALITATIVE ACETYLCHOLINESTERASE ISOENZYME IN AMNIOTIC FLUID

The measurement of amniotic fluid (AF) acetylcholinesterase isoenzyme (AChEI) is a relatively new method for early diagnosis of open neural tube defects (NTDs). As quantitative methods are of unproven reliability at present, the authors used a high resolving power qualitative method-vertical slab polyaerylamide gel electrophoresis. The benefits of this technique are: simplicity of operation, accuracy, unsophisticated equipment, and easily available reagents. Combined results of 9 NTDs studies revealed that samples from early pregnancy gave more accurate results than those from late pregnancy.     

Assessment of sublingual immunotherapy efficacy in children with house dust mite-induced allergic asthma optimally controlled by pharmacologic treatment and mite-avoidance measures

Although several studies have demonstrated the efficacy of subcutaneous immunotherapy in allergic asthma, few have shown the same benefit using sublingual immunotherapy (SLIT) in asthmatic patients. This study was conducted to assess the efficacy of house dust mite (HDM) SLIT in addition to allergen avoidance and standard pharmacologic treatment. A double-blind, placebo-controlled trial was performed in 111 children (aged 5-15 yr) with HDM-induced mild-to-moderate asthma. After a 4-week baseline phase, patients were randomly assigned to receive SLIT with tablets of HDM extract (n = 55) or placebo (n = 56) for 18 months. Pharmacologic treatment was adjusted every 3 months following a step-down approach. Asthma symptom scores, reduction in use of inhaled corticosteroids and inhaled beta(2)-agonists, rhinitis symptoms, lung function tests, skin sensitivity to HDM, dust mite-specific immunoglobulin (Ig) E and IgG(4), and quality of life (QoL) were assessed during the study. After 18 months of treatment, diurnal and nocturnal asthma symptoms scores did not show significant differences between SLIT and placebo groups. Inhaled corticosteroids and inhaled beta(2)-agonists use was reduced in both groups without significant differences between groups. There were no significant differences in lung function (forced expiratory volume in 1 s and peak flow rate variations) between groups. Rhinitis symptom score decreased in both groups, with no difference between the two groups. The severity dimension of QoL was significantly improved in the SLIT group (age 6-12 yr). SLIT induced a significant reduction of skin sensitivity to HDM (p < 0.01) and a significant increase in HDM-specific IgE and IgG(4) antibodies (p < 0.001) in the SLIT group compared with the placebo group. SLIT was well tolerated with mild/moderate local adverse events. No severe systemic reactions were reported. This study indicates that, when mild-moderate asthmatic children are optimally controlled by pharmacologic treatment and HDM avoidance, SLIT does not provide additional benefit, despite a significant reduction in allergic response to HDM. Under such conditions, only a complete, but ethically unfeasible, discontinuation of inhaled corticosteroid would have demonstrated a possible benefit of SLIT.     

Factors influencing survival of reconstructions. Consensus report of Working Group 2

Abstract: In order to evaluate the level of evidence of factors influencing the survival of reconstructions, systematic reviews of the relevant literature were prepared by a group of rapporteurs. The review papers were circulated to the members of the group before the conference and formed the basis for group and panel discussions. Subsequently, modifications were added to the review papers, and suggestions for consensus statements concerning the following topics were prepared and again critically reviewed in the group and in the plenum: Impact of (i) periodontal disease on the survival of tooth-supported reconstructions, (ii) post-surgical factors as supportive therapy on the survival of implant supported reconstructions, (iii) technical and/or biological complications on the survival of different types of reconstructions, (iiii) material choice for reconstructions on the survival of single crowns and fixed dental prostheses.
