慢性乙型肝炎的中医药生态治疗优势

现代医学的生物、心理与社会医学模式特点之一是对以身心疾病为主的现代疾病的预防和治疗 ,更加注重人体的整体性、强调药物作用的多靶点性 ,即整体调节作用。运用中医学的整体观与辩证论治治疗慢性疾病。如肝病的生态治疗就是发挥绿色天然中药复方的多重综合、双向调节功能 ,调动人体的防御机能 ,强调药物作用的多靶点性及整体调节作用以清除病毒、调节免疫、增强抵抗力、恢复肝功能、防止肝炎的慢性纤维化     

冷冻食品中损伤大肠菌群的修复探讨

目的：为了准确测定冷冻食品中大肠菌群含量。避免对冷冻损伤大肠菌群的漏检。方法：应用营养物质丰富的营养肉汤，对冷冻损伤的大肠菌群在接触选择性培养基前在37℃孵育2h。结果：营养肉汤在37℃孵育冷冻损伤大肠菌群2h后，选择性平皿上菌落数与非选择性平皿上菌落数相当，细菌未发生显著繁殖；在实际样品应用试验中，提高了大肠菌群阳性样品的检出率。结论：应用营养肉汤37℃孵育冷冻损伤大肠菌群2h，可使其得到良好的修复，此修复过程是对常规检测大肠菌群方法的改进和完善。     

The change process in alcoholics: client motivation and denial in the treatment of alcoholism within the context of contemporary nursing

Despite being constantly cited as a critical intervening variable in the recovery from alcohol problems, there is a paucity of literature on client motivation. This paper reviews the current literature which impacts on motivation and its importance in treatment and develops in a stepwise manner the revised expectancy/motivation hypothesis, tentatively explaining both motivation and denial as a natural process in behavioural change. Because of the revised expectancy/motivation hypothesis' distinctly defined stages which closely relate to the process of nursing and the qualitative and quantitative measurement it entails which the nursing process demands, it offers a particularly appropriate model for treatment within nurse practice.     

口服维生素K1对新生儿维生素K缺乏诱导蛋白的影响

目的 探讨口服维生素K1（VK1）对新生儿VK缺乏症诱导蛋白Ⅱ（PIVKA－Ⅱ）的影响及口服VK1的最佳剂量。方法 随机将101例足月新生儿分为口服VK1 2.5mg组、5mg组及对照组三组，出生时均采集脐血，用酶联免疫吸附法测定PIVKA－Ⅱ含量，3d后复查三组新生儿血PIVKA－Ⅱ含量。结果 PIVKA－Ⅱ≥2mg/ml人数2.5mg组由8例降至4例，5mg组由11例降至2例，对照组由11例降至8例。经统计学处理，2.5mg组与5mg组比较P＞0．05；口服VK1组与对照组比较P＜0．05。结论 PIVKA－Ⅱ的变化与口服VK1剂量的差异无显著性。     

高效液相色谱法测定肺癌患者尿中假尿嘧啶核苷和肌苷量比值

目的：通过检测肺癌患者尿液中假尿嘧啶核苷和肌苷量比值，探讨其在肺癌诊断中的应用价值。方法：肺癌患者、肺良性疾病及对照组各50例，分别收集其晨起空腹尿液，离心过滤后利用高效液相色谱法同时检测假嘧啶苷及肌苷，计算假尿嘧嘧与肌苷量比值。结果：肺癌患者中尿液中n（假尿嘧啶核苷/n（肌苷）比值有明显升高，与正常人比较差异有统计学意义，但肺良性疾病组与正常组和肺癌组比较，差异无统计学意义。结论：假尿嘧啶核苷对肺癌诊断并非特异性肿瘤标志物，但可以作为肺癌早期诊断的一种辅助指标。     

面对《医疗事故处理条例》的实施医院应采取的对策

为实施《医疗事故处理条例》,必须加强医院自身建设,规范管理。并从强化教育、严格准入制度、健全规章制度,规范病案与物证管理,尊重患者知情同意权,及时化解纠纷,分摊风险责任,维护合法权益等八个方面进行研讨提出对策。     

斑点膜型HBsAg和HIV抗体联合检测试剂盒的研制及评估

为了方便入出境人员，及时有效地防止传染病的传入和传出。我们研制了斑点膜型乙肝、艾滋病联合酶联免疫快速检测试剂盒(DsELISA)．该试剂盒用硝酸纤维素膜作固相载体，将抗-HBs单克隆抗体，艾滋病I型抗原和抗-鼠IgG多克隆抗体分别包被于其上，再用辣根过氧化物酶标记的抗-HBs单克隆抗体和抗人IgG单克隆抗体检测样本中的乙型肝炎表面抗原(HBsAg)和艾滋病病毒抗体(抗-HIV)．在检测中，HBsAg的最低可检出浓度要少于2ng／ml，而且全部检测过程在8分钟内即可完成，对于280份已确诊的血清样本的检测结果表明，HBsAg和抗-HIV的总符合率分别为99．7%和100%，我们认为，我们研制的DsELISA具有高度的精确性．敏感性，稳定性和特异性，方便了入出境人员，适合于口岸现场入出境的查验和传染病监测体检的要求.     

Risk of lung cancer among patients with head and neck cancer

A cohort of 5180 patients with head and neck cancer, who were part of the tumor registry of the Surveillance, Epidemiology, and End Results area of western Washington State, was followed up for as many as 15 years to determine the risk of lung cancer. A sample of 522 patients from this cohort was interviewed to determine smoking history. Lung cancer developed in 356 (6.9%) of the 5180 patients. The overall annual incidence of lung cancer remained relatively constant between approximately 1.0% and 2.0% during the 15 years of follow-up. Men had an increased risk of lung cancer compared with women (relative risk [RR] = 1.56; 95% confidence interval [CI] = 1.18 to 2.03). Compared with patients with oral cavity cancer (RR = 1.00), the relative risk of lung cancer developing by the site of the index tumor was 0.63 (95% CI = 0.40 to 0.98) for lip, 1.12 (95% CI = 0.81 to 1.56) for intrinsic larynx, 1.73 (95% CI = 1.21 to 2.47) for oropharynx, 1.84 (95% CI = 1.16 to 2.92) for hypopharynx, and 2.28 (95% CI = 1.60 to 3.24) for extrinsic larynx. Among the 522 patients who were interviewed, men smoked more than women ( p < 0.0001), and patients with laryngeal or pharyngeal cancer smoked more than patients with cancer of the lip or the oral cavity ( p < 0.05). Among patients with head and neck cancer, the risk of lung cancer is highest for men and for patients with cancer of the pharynx or extrinsic larynx. These findings may be explained by differences in smoking consumption. (Otolaryngol Head Neck Surg 1997;116:630-6.)
