Objective To analyze the current research status of fibrobronchial bronchoalveolar lavage(BAL)in China,explore the development context and research hotspots.Methods This study was conducted from 2003 to 2023 by searching the Chinese literatures on fibrobronchial BAL collected from China National Knowledge Infrastructure,Wanfang Data Knowledge Service Platform,VIP and SinoMed,and extracting the information of keywords,authors,institutions and publication time of the literatures.Co-Occurrencel4.9,VOSviewer 1.6.19 and Microsoft Excel 2021 were applied to carry out data cleaning,data statistics and graph rendering,and visualized the research hotspots and trends of fibrobronchial BAL.Results A total of 4219 literatures meeting the requirements were included.The largest number of articles will be 438 in 2021.There were 522 core authors with more than 3 published papers.The institutions and journals with the largest number of publications were Hebei Children's Hospital with 26 articles and Journal of Clinical Pulmonary Medicine with 154 articles respectively.The research hotspots mainly include pneumonia,pulmonary infections,clinical efficacy,bronchoalveolar lavage fluid,bronchiectasis,and mechanical ventilation.Conclusion Fibrobronchial BAL is widely used in the diagnosis and treatment of respiratory diseases in China.In the future,it is necessary to strengthen the cooperation among researchers,deepen the theoretical basis,improve the clinical application system,and promote the further development of respiratory department in China.

Objective To evaluate the ability of the ratio of peripheral blood white blood cell(WBC)counts to platelet counts to predict the onset of radiation-induced thymic lymphoma(TL)in a mouse model.Methods Mice were subjected to fractionated total-body irradiation(TBI)to established a TL model before the changes of the WBC-to-platelet ratio during the development and progression of TL were investigated.Four-week-old male C57BL/6J mice were randomized into the normal(non-irradiation)group and radiation exposure group that was subjected to 1.8 Gy TBI once weekly for four consecutive weeks.The survival and TL-incidence of those two groups were compared within 370 days of TBI.Histomorphology and hematoxylin & eosin(H&E)staining of the thymus were used for definite diagnosis of TL while flow cytometry was adopted to detect the frequency changes of T cells in the thymus,bone marrow and spleen.Peripheral blood(PB)cell counts were measured to analyze the changes of peripheral hemogram during TL pathogenesis.Results No mice in the normal group were diagnosed with TL while 83％of the irradiated mic suffered from TL within 370 days of fractionated TBI(P＜0.0001).Using histopathologic technology,medium-sized tumor cells were observed in the thymus of irradiated mice diagnosed with TL.Cytometric analysis showed decreased frequencies of CD4 mono-positive cells and increased frequencies of CD8 mono-positive cells in the thymus,bone marrow and spleen of mice diagnosed with TL.PB analysis displayed a significant increase in the WBC-to-platelet ratio one week prior to the TL-caused death in the irradiated mice(P＜0.01).Conclusion Elevation of the peripheral blood WBC-to-platelet ratio can help predict the onset of IR-induced TL of mice.

Objective To establish mixed-sandwich ELISA detection system by screening aptam-ers of MPT64 antibodies with SELEX to detect clinical serum samples, and explore the potential laboratory diagnosis value of this method. Methods To detect the affinity of the final round ssDNA library to MPT64 antibodies inhibited by MPT64 antigen with the competitive ELISA method, optimize the mixed-sandwich ELISA detection method that was aptamer-serum-horseradish peroxidase labeled goat anti-human IgG anti-body detection system to detect 230 cases of clinical serum samples as well as the lowest concentration of MPT64 antibodies and the linear range. Results In competitive ELISA test results, the percentage of inhi-bition effect of MPT64 antigen to final round ssDNA library is from 0.25% to 80% when the MPT64 antigen concentration rised from 2 μg/ml to 256 μg/ml. The Optimized detection system of mixed-sandwich ELISA was constitute of the concentration of ssDNA coated with 0.1μg/hole, serum dilution of 1/200, horseradish peroxidase labeled goat anti-human IgG antibody concentration of 1/40 000. The lowest concentration of MPT64 antibody is 3 mg/L and the linear range is between 10 mg/L and 1000 mg/L. The serum samples of 100 cases of tuberculosis patients, 100 healthy individuals and 30 cases of non-tuberculesis were tested in this system and the test result was analyzed with Graphpad Prism, the difference of tuberculosis group and healthy group was statistically significant (P<0.001 ), the difference of TB group and non-TB control group was also statistically significant (P<0.001). The specificity and the sensitivity was 96.1% and 31.0% re-spectively. Conclusion The aptamer mixed-sandwich ELISA method will play an important role in the sero-logical diagnosis of tuberculosis.

The objective of this study was to elucidate the effect of human placenta adherent cells (hPDAC) on expansion of human umbilical cord blood CD34(+) cells in vitro. hPDAC was isolated and characterized in human placenta tissue by using enzyme-digesting method and flow cytometry. A co-culture system was established with hPDAC and cord blood CD34(+) cells. The CD34(+) cells were cultured in different culture systems with different combinations of hPDAC and SCF, IL-3, IL-6 and FL. The number of total nucleated cells, CFC and CD34(+) cells were repeatedly counted in culture for 4 weeks. The results showed that the hPDAC displayed fibroblast-like morphology, and were positive for CD29, CD44, CD166, HLA-ABC and UEA-1, and negative for CD34, CD45 and HLA-DR. Functionally, ex vivo expansion of CD34(+) cells on feeder layer of placental adherent cells was significantly higher than that no feeder layer group. SCF + IL-3 + IL-6 + FL + hPDAC manifested the most potent combination, with the number of total nucleated cells increasing by (126.0 +/- 6.7)-fold, progenitor cells (CFC) (49.8 +/- 1.7)-fold and CD34(+) cells (8.3 +/- 1.65)-fold. It is concluded that placental adherent cells could support hematopoiesis in vitro and work as a suitable feeder layer for cord blood stem/progenitor cell expansion.
