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.

ABSTRACT
Objective To study the long-term follow-up results of Ross surgery.Methods Between October 1994 and February 2009,58 consecutive patients underwent a Ross procedure at our institution.The right ventricular outflow tract was repaired with a cryopreserved pulmonary homograft.All patients were scheduled for a yearly study thereafter that ended at the time of death or at closure of the follow-up visit.Mean follow-up was (12.6 ± 5.8) years (range:4.5 to 18.2 years).Results There were two early deaths (3 ％)and one late death (2％).Acturial survival at 16 years was (94.8 ± 3.1) ％.One patient required reoperation 1.5 years after his first Ross operation.Of the 55 survival patients,42 patients(76％) were in NYHA functional class Ⅰ and 13 patients(24％) were in NYHA functional class Ⅱ.Grade 1 or grade 2 autograft regurgitation was observed in seven patients(12％) at one year after the surgery.The sinus of Valsalva diameters were all ＜ 40 mm in these seven patients.Mter surgery,freedom from hemodynamically relevant autograft regurgitation was(87.9 ± 2.8) ％ at 16 years,whose left ventricular function was significantly improved and left ventricular end-diastolic diameter recovered to normal over the long term.None of the patients required reoperation due to pulmonary homograft failure.Conclusion The Ross procedure can be safely performed in patients with aortic valve disease.To date,mortality,morbidity,and reoperation relates are very low.Reasons for these superior results may include the following:diameter of the aortic valve annulus matching that of the pulmonary valve and patients were monitored with antihypertensive medications to keep systolic blood pressure under 120mmHg(1 mmHg =0.133kPa) to delay pressure lesions to the pulmonary autograft.
ABSTRACT
Objective To study the relationship between heart rate and failure of biological valve,and whether reduce the heart rate could delay the failure of biological valve.Methods Retrospective analysis of 92 bioprosthetic valve replacement cases in our institution from April 1996 to March 2001.The follow-up was carried out through the outpatient service,telephone and letter.The patients were divided into two groups based on the heart rate:Group A:basic heart rate no more than 75 beats per minute;Group B:basic heart rate greater than 75 beats per minute.Blood pressure,heart function,echocardiogram and reoperation rate was collected.Results In group A,the average follow-up time and the longest follow-up time was better than the patients in group B but has no significant difference.Echocardiographic data showed that the proportion of valve leaflets stiffness and calcification in group A was significantly lower than group B(7.7％ vs.17.9％,P ＜0.05).Redo operation rate in group A was lower than those in group B (7.7％ vs.22.6％,P ＜ 0.05).There were only 1 case(1.5 ％) suffering from the tearing in all three valve leaflets in group A while it was 8 cases(8.7％) in group B (2.6％ vs.15.1％,P ＜ 0.05).Conclusion Basic heart rate has a significant effect on the failure of the mitral bioprosthesis.To decrease the basic heart rate can delay the failure of the mitral bioprosthesis and improve the durability.
ABSTRACT
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.
