随着人们生活水平的日益提高，对美的要求也越来越高。牙齿美自治疗经历了氧化物温热外漂白法、家庭漂白法、激光漂白法、树脂贴面、烤瓷牙修复等过程。但它们都不同程度地存在美白效果不理想、稳定性差或对牙齿有损害等缺点。Beyond冷光美白法由于其使用安全，美白效果显著，操作时间短，成为牙齿美自治疗新宠^[1]。[第一段]     

Clinical and laboratory characteristics of 75 patients with specific polysaccharide antibody deficiency syndrome.

BACKGROUND: There are limited studies of large cohorts of patients with specific polysaccharide antibody deficiency (SPAD) syndrome. OBJECTIVE: To study the clinical and laboratory characteristics of patients with specific polysaccharide antibody deficiency syndrome. METHODS: We retrospectively studied 75 patients with total IgG levels of at least 500 mg/dL and fewer than 9 of 12 responses to vaccination with pneumococcal vaccine polyvalent. Exclusion criteria included an IgG level less than 500 mg/dL, established immunodeficiency syndrome, and secondary immunodeficiency. RESULTS: The most common clinical presentation was frequent infections (n = 69; 92%), including sinusitis (n = 53; 77%), pneumonia (n = 29; 42%), ear infections (n = 18; 26%), and bronchitis (n = 19; 28%). Other presentations were systemic infections (n = 5; 7%), autoimmune or rheumatic diseases (n = 6; 8%), and chronic diarrhea (n = 4; 5%). The median IgG2 level of patients with no response to pneumococcal vaccine polyvalent tended to be lower than that of patients with at least 1 response (150 vs 193 mg/dL, respectively; P = .06). There was no association between total IgG level (categorized as 500-600 or > or = 600 mg/dL) and frequency of infection (P = .43). Patients with fewer responses to pneumococcal vaccine polyvalent and a higher frequency of infections were more likely to receive intravenous immunoglobulin (IVIG) therapy (P = .01 and .003, respectively). Treatment with IVIG significantly reduced the number of infections (P < .001). CONCLUSION: Patients with no response to pneumococcal vaccine polyvalent tended to have lower IgG2 levels; those with fewer responses were more likely to receive IVIG therapy.     

Vitapex糊剂用于患儿根尖诱导成形术的护理配合

根尖诱导成形术（apexficaotion，AP）是指牙根未完全形成之前，在消除感染或尖周炎症的基础上，用药物诱导根尖部牙髓和俄根尖周组织，使牙根继续发育并使根尖形成，行永久性充填。2002年-2005年我科将Vitapex糊剂用于儿童患牙行根尖诱导成形术，效果较好：现将护理配合介绍如下。     

数字减影子宫输卵管造影术

目的:介绍和评价数字减影与自动高压注射器联合应用于子宫输卵管造影(HSG)。方法:自行设计造影用硅胶管使之能与自动高压注射器相联接,用40%泛影葡胺和数字减影方法作造影;随机抽取常规透视点片碘油造影片44份,数字减影泛影葡胺造影片50份进行对照分析。结果:两组比较:清晰度宫腔无显著性差异(P>0.05),输卵管有显著性差异(P<0.05);输卵管通畅率、血管或(和)淋巴管回流率有显著性差异(P<0.05)。盆腔涂布无显著性差异(P>0.05)。结论:采用数字减影与高压注射器行子宫输卵管造影能提高造影质量。     

~3H-α-第二丁基对羟基苄醇在家兔体内的药物动力学研究

本文报道给家兔注入不同剂量的~3H-α-第二丁基对羟基苄醇,观察该药在其体内的药物动力学。结果表明,血中分布相快,消除相慢,消除半衰期T_1/1β为12h。经F值检验和理论计算值与实测值的契合程度比较,表明该药在兔体内的运转符合二室开放模型的动力学方程。     

西宁地区冠心病113例临床分析

本文通过西宁地区１１３例住院冠心病人的临床分析，认为西宁地区冠心病患病率低，患者年龄大，男性患病率高于女性，而且绝经期后的高龄女性患者患病率仍然远比男性低，这些与低海拔地区不同。而冠心病各型的分布、临床症状、病死率等与低海拔地区相似。     

腺苷对突触体^45Ca摄取的抑制作用

用同位素标记~(15)Ca法测定大鼠突触体内游离钙的浓度,探讨了腺苷对高钾、N-甲基-D-天冬氨酸(NMDA)谷氨酸(Glu)等刺激所致的Ca~(2 )内流增加的影响。结果发现腺苷在10nmol/L～0.1μmol/L范围内对高钾、NMDA、Glu等刺激所致的Ca~(2 )内流有抑制作用,并呈剂量依赖关系,最大抑制率分别为41.68±7.68％、31.32±6.17％、37.52±2.29％。这可能是腺苷对缺血性脑损伤保护作用的机理。     

鼻胆管引流灌注治疗急性胰腺炎的临床价值

目的　探讨鼻胆管引流灌注 (ENBD)治疗急性胰腺炎的临床价值。方法　 40例经B超或CT检查无胆总管、肝总管结石的急性胰腺炎患者随机分为ENBD治疗组和对照组 ,ENBD治疗组在常规逆行性胰胆管造影 (ERCP)检查时做胆汁常规检查及细菌培养 ,术后留置鼻胆管引流并交替应用 0 .9%氯化钠 5 0ml +庆大霉素 8万U 8h和 0 .5 %灭滴灵 5 0ml 8h灌注持续 3～ 5d ,对照组应用善宁 0 .1mg皮下注射 8h持续 3d并观察其 1年内的复发情况。结果　ENBD治疗组 2 0例患者胆汁中均发现有白细胞及黄、黑色泥沙样物 ,6例培养出微生物 ( 3 0 % ) ,ENBD治疗组与善宁治疗组的腹痛消失时间分别为 ( 8.45± 8.40 )h和 ( 3 8.10± 3 5 .43 )h(P =0 .0 0 2 ) ,血清淀粉酶恢复至正常所需时间分别为 ( 18.0 0± 8.2 6)h和 ( 5 6.40± 48.80 )h(P =0 .0 0 2 ) ,两组的 1年复发率分别为 5 %和 40 % ,其差异均有非常显著性 (P <0 .0 1)。结论　鼻胆管引流灌注治疗急性胰腺炎疗效确切而安全 ,能减少复发 ,胆汁淤积和感染在急性胰腺炎的发病中起重要作用。
