RESUMO
【Objective】 To form the sampling data interval by retrospectively analyzing the sampling data of quality monitoring of fresh frozen plasma, cryoprecipitates and leukocyte-free platelets in all blood stations in Hebei Province during the past 7 years. 【Methods】 The data of blood component sampling from 12 blood station quality control laboratories in Hebei from 2015 to 2021 were collected. The FⅧ content and plasma protein content of fresh frozen plasma, the FⅧ content and fibrinogen content of cryoprecipitates, and the leukocyte residuals, red blood cell mixed and platelet content of leukocyte-free platelets were taken as the objects for discrete point and fitted curve analysis. 【Results】 The FⅧ level of fresh frozen plasma: (1.36±1.1) IU/mL, 5 blood stations showed a representative overall high or low or fluctuated characteristics; Fresh frozen plasm-plasma protein items: overall mean ±SD: (61.13±16.7) g/L, four blood stations showed scattered distribution or continuous high value scattered points; Cryoprecipitates FⅧ: the overall mean ±SD: (134.25±58.7) IU/mL, four blood stations showed the differentiation characteristics of continuous high, low or stable in the middle; Cryoprecipitates-fibrinogen items: the overall mean ±SD: (215.27±83.5) mg, five blood stations showed the overall high or low and fluctuated. Leukocyte-free apheresis platelet-to-leukocyte residual items: overall mean ±SD: 0.37±0.96 (×106/bag), two blood stations showed a relatively high representative overall characteristics, and the rest were concentrated between 0 and 1; The total mean ±SD of platelet-to-red blood cell mixture without leukocyte was 2.45±2.82 (×109/bag), with obvious segmented concentrated distribution, and scattered distribution in 3 blood centers. Platelet content: the overall mean ±SD was 3.14±1.55 (×1011/bag), many deviations were noticed in 3 blood stations, and 1 blood station showed representative overall high characteristics. 【Conclusion】 This analysis shows that the distribution status of each blood station in different items is similar. The distribution status of discrete point groups and the change trend of the concentrated part of the fitting curve show that there are some differences in the monitoring level between the quality control laboratories of each blood station, and the update of detection instruments and reagents and the selection of detection methods greatly affect the test results. The summary data presented the index interval framework formed in the past 7 years, which helped to understand the difference between the results of each laboratory, correct the accuracy of the test results, better play the guiding role of quality monitoring in the blood preparation process, and continue to enhance the standardization of the whole process of blood collection and supply in the province.
RESUMO
Objective To approach the pathogenesis,diagnosis and treatment of cystitis glandularis. Methods A retrospective analysis of clinical data of 172 cases of cystitis glandularis was made and the experience on its diagnosis and treatment was summed up.Transurethral electroresection was performed in 132 cases.Of these cases,93 with lower urinary obstruction simultaneously underwent electroresection of pathological foci of lower urinary obstruction caused by bladder-neck contracture or hyperplasia of seminal colliculus,and 16 cases with complicated hymenal lesion at meatus urinarius received resection and plastic operation of hymenal lesion.Instillation of drug at bladder trigone was performed in 40 patients who refused surgical operation and in 16 patients whose symptoms still existed after electroresection. Results Seventy-eight of the 132 cases in which transurethral electroresection had been performed showed normal findings in cystoscopy during a follow-up study of 6～36 months;their symptoms disappeared,the cure rate being 58%.Thirty-two of the 56 cases for whom bladder trigone instillation had been performed had their symptoms subsided or remitted,the effective rate being 57%. Conclusions The lower urinary obstruction is the common cause of leading to cystitis glandularis.Transurethral electroresection or electrovaporization is the main method of treating cystitis glandularis.It can also simultaneously remove obstructive foci which causes cystitis glandularis.The bladder trigone instillation is an effective method of treating cystitis glandularis.
