ABSTRACT
In recent years, the IVD industry has developed rapidly based on the increasing market demand, and plays an important role in disease prevention, clinical diagnosis, health monitoring and guiding treatment. Therefore, followed quality and safety issues are highly concerned. The unique advantages of blockchain technology, decentralization, distrust and non-tampering, can write into trusted node data in every link covering production, circulation and usage of IVD reagents, and establish a distributed ledger with full backup, which makes the anti-conterfeiting and traceability for IVD reagents possible. We discuss whole process intelligent tracing system for IVD reagents based on blockchain technology. Through the strong mechanism of pre-supervision and post-punishment, the source of reagents can be traced, quality and responsibility can be investigated, and the medical inspection quality and diagnostic safety can be guarded.

Objective To analyze the status of mycoplasma infection and drug resistance in the local area,and provide the ba-sis for clinical rational drug use.Methods The specimens obtained from 1 9 530 patients with urogenital tract infection were detec-ted by adopting mycoplasma culture,identification and drug sensitivity integration kit.Mycoplasma infection and drug susceptibility were analyzed.Results In the total of 1 9 530 suspected patients specimens,1 1 1 78 cases were positive with a positive rate 57.24%.The positive rate of ureaplasma urealyticum (Uu)and mycoplasma hominis (MH)was 44.63% and 0.44% respectively and the positive rate of Uu and Mh mixed infection was 12.1 7%.The positive rate of female was higher than that of male and the difference was statistically significant(P <0.05).The positive rate of mycoplasma in 2008-2014 was on the rise;The sensitive rate of mycoplasma to josamycin,doxycycline,minocycline element,clarithromycin was 88.57%,84.32%,76.09% and 71.53% respec-tively,mycoplasma was highly drug resistance to quinolone antibiotics;mixed infection resistance was higher than that of single in-fection;The number of drug resistance of Uu,MH and Uu+MH to 12 kinds of antibiotics increase.Conclusion Mycoplasma infec-tion in urogenital tract is mainly caused by Uu and Mh infection is in mixed infection way;josamycin,doxycycline is the first choice for treatment of mycoplasma in this region.Rational drug choise can be based on the drug susceptibility test.Multiple drug resist-ance of mycoplasma is serious and should be paid attention to.
