第十五届中国（）检验医学暨输血仪器试剂博览会健仑体验

为期3天的第十五届中国（）检验医学暨输血仪器试剂博览会于17日在重庆博览中心拉开帷幕。今年是该展会*在重庆举办，活动时间持续至3月20日。展会吸引近800家展商来渝参展，参展人次达8万余人。

中国()检验医学暨输血仪器试剂博览会(CACLP春季会)始创于1991年，它的前身是全国医学检验用品产供销联谊会，经过二十六年来的不断发展和壮大，CACLP春季会已成为国内规模zui大、参展企业zui多、展会内容zui丰富、专业性zui强、影响力zui广、参会人数zui多的专业性商业展览会。该展会已成为*规模zui大的体外诊断商业展。广州健仑生物科技有限公司，作为华南地区IVD产业的*，积极参与到CACLP春季会的交流盛宴当中。

  本届展会四方学者齐聚，业内精英云集，让我们拓展了视野，丰富了阅历，饱满了人生。我们感激行业里的老师与前辈，感激他们传授我们知识，让我们拥有学习的能力；我们感激一直支持和鼓励我们的客户，感激他们一直默默的帮助，让我们在“星星之火”的路上不断进取与创新；我们感激一直研发与在路上成长同伴们，因为你们让我们团队更加丰富与勇敢地担当我们的社会责任。感谢一直关注健仑和陪伴健仑成长的朋友们。闻道有先后，术业有专攻，广州健仑生物科技公司将吸取CACLP春季会上丰富的知识，进而更好的服务于体外诊断行业的各个领域，为推动体外诊断产业不断进步而努力。致谢！

2．H抗原：为蛋白质，对热不稳定，60℃经15分钟或乙醇处理被破坏。具有鞭毛的细菌经甲醇液固定后，其O抗原全部被H抗原遮盖，而不能与相应抗O抗体反应。H抗原的特异性取决于多肽链上氨基酸的排列顺序和空间构型。
沙门氏杆菌的H抗原有两种，称为第1相和第2相。第1相特异性高，又称特异相，用a、b、c等表示，第2相特异性低，为数种沙门氏杆菌所共有，也称非特异相，用1、2、3等表示。具有第1相和第2相H抗原的细菌称为双相菌，仅有一相者称单相菌。每一组沙门氏杆菌根据H抗原不同，可进一步分种或型。H抗原刺激机体主要产生lgG抗体。
3．Vi抗原：因与毒力有关而命名为Vi抗原。由聚-N-乙酰-D-半乳糖胺糖醛酸组成。不稳定，经60℃加热、石碳酸处理或人工传代培养易破坏或丢失。新从患者标本中分离出的伤寒杆菌、丙型副伤寒杆菌等有此抗原。Vi抗原存在于细菌表面，可阻止O抗原与其相应抗体的反应。Vi抗原的抗原性弱。当体内菌存在时可产生一定量抗体；细菌被清除后，抗体也随之消失。故测定Vi抗体有助于对伤寒带菌者的检出。
2. H antigen: a protein that is thermally unstable and destroyed at 60°C for 15 minutes or ethanol treatment. After the bacteria with flagella were immobilized in methanol solution, all of their O antigens were covered by H antigen and could not react with the corresponding anti-O antibodies. The specificity of the H antigen depends on the order and spatial configuration of the amino acids on the polypeptide chain.
There are two types of Salmonella H antigen, which are called the first phase and the second phase. The first phase has a high specificity, also known as a specific phase, and is represented by a, b, c, etc. The second phase has a low specificity and is shared by several Salmonella species, and is also called a non-specific phase. It is expressed as 1, 2, 3, etc. . Bacteria having the first phase and second phase H antigens are called biphasic bacteria and only one phase is called monophagic bacteria. Each group of Salmonella is different depending on the H antigen and can be further divided or typed. H antigen stimulates the body to produce lgG antibodies.
3. Vi antigen: named as Vi antigen due to its virulence. It consists of poly-N-acetyl-D-galactosamine uronic acid. Unstable, easily destroyed or lost by heating at 60°C, treatment with stearic acid, or artificial subculture. Newly isolated from the patient's specimens of typhoid bacillus, paratyphoid paratyphoid bacillus and other antigens. The Vi antigen is present on the surface of the bacteria and prevents the reaction of the O antigen with its corresponding antibody. Vi antigens are weakly antigenic. A certain amount of antibodies can be produced when bacteria are present in the body; after the bacteria are removed, the antibodies disappear. Therefore, the determination of Vi antibody helps detection of typhoid carriers.
