Objective:To visually analyze the research literature on the analysis of TCM compounds; To explore the research hotspots and trends in this field.Methods:The literature related to the disassembly analysis of TCM compounds was retrieved from CNKI, Chongqing VIP, Wanfang Data, SinoMed, and China Medical Journal Full-text Database from January 1, 1981 to December 31, 2024. CiteSpace 6.4.R1 software was used to visualize the number of articles, authors, institutions and keywords, and to draw the cooperation network diagram of authors and institutions, keyword co-occurrence, clustering, timeline and burst map.Results:A total of 1 728 Chinese articles were included, and the number of publications showed a fluctuating upward trend. A comparatively high number of publications was in 2007 and 2016, followed by a slight decline but maintained at a high level. There is a trend of recovery in 2024. The author with the highest number of articles was Professor Fang Zhaoqin, and the institution with the highest number of articles was Beijing University of Chinese Medicine. High frequency keywords included rats, compatibility, experimental research, cell apoptosis, TCM compound, and a total of 19 clusters and 25 emergent keywords were formed.Conclusions:The research contents and methods of the research on the disassembly of TCM compounds are relatively rich, and there are many explorations on classical prescriptions. The study of disassembled prescriptions has played a driving role in the modernization of TCM compounds. In the future, high-quality cooperation between regions, institutions, and authors, combination with modern medicine and scientific methods, will further improve the quality of research in this field.

Objective To investigate the factors affecting the isolation of fastidious bacteria such as Streptococcus pneumoniae and Haemophilus influenzae from lower respiratory tract specimens in children.Methods A total of 210 lower respiratory tract specimens from children were collected and inoculated on both blood agar plate and chocolate agar plate 0.5 h,2 h,6 h,12 h,and 24 h after collection.The effect of specimen turnaround time,transport medium,and inoculation medium on the isolation of fastidious bacteria was studied.Results The results of 200 qualified specimens showed that the isolation of S.pneumoniae and H.influenzae significantly decreased with the increasing of specimen turnaround time (P＜0.05),but no significant difference was observed between 0.5 h and 2 h timepoints.The isolation of fastidious bacteria in semi-solid medium was non-significantly higher than the other two transport medium (P＞0.05).No significant difference was found in the isolation and growth ofS.pneumoniae and H.influenzae on different inoculation media (P＞0.05).Conclusions The appropriate specimen turnaround time,transport medium,and inoculation medium are important for improving the isolation of fastidious bacteria from lower respiratory tract in children.

Objective To prepare a detective membrane strip for detection of food allergen-specific IgE in serum samples and estimate its clinical application value in allergic diseases. Methods The crude extracts of the food allergens were prepared. Nitrocellulose membrane as the solid support was selected and the coating and the detecting conditions were optimized. The membrane strips were used to detect serum samples in 210 patients with allergic diseases and the results were compared with German Allergy Screentesting system. Results The optima] experimental conditions were as follows: The NC membrane was adopted as the solid support. After being spotted, the food allergens were incubated for 2 hours at room temperature, followed by 2% PVA blocking for 1 hour. After serum samples were diluted (1: 10) and incubated for 2 hours at room temperature, the concentration of anti-human IgE was 2 μg/mL Compared with the German Allergy Screen-testing system, their positive detectical coincidence was 63.6%, and negative detectical coincidence was 94. 6%. The two methods had no difference in detecting the majority of food allergens such as egg white, milk, peanut, soybean, crab and shrimp (X2 2.53, 2.40, 2.08, 2.38, 0.17,1.13, P>0.05). Conclusions The advantages of our method for detecting allergic diseases are little serum needed, multiple detective allergens, simple manipulation and low cost. This method has obvious clinical application value, which should be a new detective method for the allergic diseases with broad perspectives.
