ABSTRACT
【Objective】 To investigate the related viral markers of HBV DNA reactive samples among voluntary blood donors in Shiyan area, so as to provide some reference for donor re-entry. 【Methods】 From August 2019 to June 2021, 78 samples with HBV DNA reactivity from voluntary blood donors in our blood station were collected, and they were further detected for HBV viral markers(using chemiluminescence assays), nucleic acid testing(NAT) of virus quantification and sequencing analysis. 【Results】 Forty-seven (60.3%)out of 78 HBV DNA reactive samples were from repeated blood donors, and 56.4%(44/78)of them were over 45 years old. Among the five viral markers of hepatitis B, 37.2%(29/78) were positive for anti-HBs alone, 19.2%(15/78) were positive for anti-HBe+ anti-HBc and anti-HBs+ anti-HBe+ anti-HBc, and 11.5% (9/78) were all items negative.A total of 62.8%(49/78) of samples were detected by NAT quantification and seven samples had been successfully sequenced for HBV. 【Conclusion】 NAT can effectively minimize the missed detection of HBsAg methodology and reduce the risk of HBV transmission through blood. The re-entry of HBV DNA reactive blood donors should be treated with care.
ABSTRACT
There are many problems in the use of Bupleurum medicinal materials such as confusion in variety, unclearness in origin and quality problems, e.g., adulteration of authentic Bupleurum and mixing of non-medicinal parts. Therefore, the quality of Chinese patent medicines containing Bupleurum chinense is variable, and it is necessary to establish targeted quality control methods. Based on the quality control methods of Bupleurum and its Chinese patent medicines, combined with the example of Xiaochaihu granules, this paper discussed the quality standard improvement and supplementary test methods of Bupleurum and its Chinese patent medicines, aiming to provide reference for the quality control, quality supervision and standardized production of Chinese patent medicines containing Bupleurum and promote the improvement of its intrinsic quality.
ABSTRACT
OBJECTIVE： To provide reference for the formulation of regulatory policies, revision and improvement of standards with the research and summary of Chinese medicine glues in recent years. METHODS： The quality problems of Chinese medicine glues found in national drug sampling inspection since 2012 were summarized, and based on this, the screening of 41 Chinese medicine glues with large production batches and large market share was carried out, and relevant supplementary inspection methods were established. RESULTS AND CONCLUSION： By summarizing the drug quality notices issued by the state and provincial and municipal drug administrations, from 2012 to 2015, it was found that the cowhide feeding in donkey-hide gelatin was serious. From 2015 to 2017, no cowhide feeding problems were found, but the feeding problems of mule and horse skins were extremely prominent. In view of the market problems, seven units completed the screening of 41 Chinese medicine glues, and established 15 supplementary inspection methods, which effectively strengthened the quality control and standardized the industrial order of Chinese medicine glues.
ABSTRACT
Se propuso los fundamentos para evaluar la calidad de la utilización del estudio complementario en el proceso de diagnóstico. Se planteó la necesidad de partir del razonamiento clínico subyacente en la indicación de dichos estudios y de tener en cuenta los momentos preanalítico y posanalítico en que el clínico participa
The fundamentals of supplementary test quality evaluation in the diagnosing process were suggested. Also, the need of taking into account the underlying clinical reasoning at the time of indicating such tests, and the pre-analytical and post-analytical moments involving the clinician's participation was stated.
