生物材料产业现状及发展战略

近年来全球医疗器械产业发展较快，其产值每年以10％的速度递增，2000年的产值约1700亿美元，药品和医疗器械产值的比例约为10：7(详见图1)。我国医疗器械虽然底子薄，技术含量较低，但近年来随着国内高新技术发展，医疗器械产业的面貌变化很大，每年以15％～20％的速度递增，在2000年国内产值约．500亿元，其中出口约100亿元，进口约200多亿元；

Mammography and 99mTc-MIBI scintimammography in breast cancer diagnosis

The aim of this work has been to evaluate whether a diagnostic protocol based on the joint use of mammography and ^99mTc-MIBI scintimammography can help to distinguish the lesions and to reduce the number of biopsies required in patients with suspected breast cancer,A total of 58 women were evaluated by palpation ,mammography,scintimammography,Twenty-four patints were scintimammographed with ^99mTc-MIBI at 10 min after injection.Thirty-four patients were taken doublepase scintimammography with ^99mTc-MIBI 10min and 60-90 min fater injection. Based on mammography,the supicion degrees of malignancy were rated,and 30 results of malignancy were confirmed by histopatology,Based on mammography,18 lesion were considered to be most probably benign (of which 3 were histopathologically breast cancer),19 as indeterminate(of which 9 were histopatologically breast cancer),and 21 as malignant (of which 18 were histopathologically breast cancer),The results of early and delayed phases ^99mTc-MIBI scintimammography were the same.The sensitivity,specificity and accuracy of scintimammography were 74.29%,86.96% and 79.31%,respectively,Scintimammography gave 16 correct diagnosis in 19 mammogram indeterminate (84.2%) and demonstrated 5 out of 8 cases axillary lymph nodes metastasis (72.5%),These studies show that ^99mTc-MIBI scintimammography used as a complementary testing technique to mammography is useful in the examination of patients with suspected breast cancer,The adoption of a joint mammography-scintimammography diagnostic protocol could considerably reduce the number of biopsies performed in patients with lesion of indeterminate mammographic suspicion of malignancy.     

奶牛乳房炎诊疗体会

奶牛乳房炎是世界范围内最常见又最难防治的奶牛疾病之一,病变主要为乳房实质、间质的炎症。病因多由机械性刺激、病原微生物侵入及化学物理性损伤所致。根据发病机理一般把奶牛乳房炎分为浆液性乳房炎、纤维素性卡他乳房炎、化脓性乳房炎、出血性乳房炎、坏疽性乳房炎和隐性乳房炎。目前全世界约有2.2亿头奶牛,其中1/3患有各     

鱼类副乳房链球菌病研究进展

副乳房链球菌Streptococcus parauberis是引起牛源和鱼源链球菌病的主要病原菌,该菌分布广、致病力强,曾给世界范围的鱼类养殖业造成重大经济损失。副乳房链球菌最初被认为是乳房链球菌S.uberisⅡ型,后经分子鉴定确定为新种,可感染包括海淡水、养殖或野生等众多鱼类发病,出现类似败血特性的临床症状,温度是其流行暴发致病的最主要诱因。根据荚膜多糖结构差异可将副乳房链球菌分为多种血清型,不同血清型对宿主的致病力不同。常规生理生化鉴定较难准确鉴别副乳房链球菌,基于PCR技术的分子鉴定是该菌的最常用检测手段。目前,药物防治仍然是副乳房链球菌病防控的首选方法,但菌株已逐渐出现耐药甚至多重耐药,尽管疫苗是最安全有效的防控措施,但商用疫苗还有待于进一步试验。此外,鉴于噬菌体的特性,其有可能成为抗生素类药物的替代品。本文梳理归纳了鱼类副乳房链球菌病原学、流行病学与临床症状、致病机制、检测方法、耐药性、防治措施等方面的研究进展,并提出今后应在加强副乳房链球菌的流行病学与致病机制、科学筛选防治药物、加大疫苗研发力度等方面开展深入研究,以期为养殖生产中鱼源副乳房链球菌病防控提供科学参考。     

急性乳腺炎的食物药物禁忌

急性乳腺炎是因金黄色葡萄球菌等细菌侵入乳腺组织而引起的急性乳房感染。本病不仅给产妇带来极大痛苦，而且治疗不当会引起无乳和缺乳。
