Methods: The journal literatures related to the prevention and treatment of pulmonary interstitial fibrosis with TCM in recent 20 years in CNKI database were searched and passed through CiteSpace 5.8.R3 generates the knowledge map of relevant literature authors, document issuing institutions and keywords, and makes visual analysis. Results: A total of 1,576 documents were included, and the annual number of documents showed a fluctuating upward trend, forming a relatively stable research team represented by authors such as LYU Xiaodong, PANG Lijian and LIU Chuang;According to the atlas of document issuing institutions, Shandong University of Traditional Chinese Medicine and its affiliated hospitals ranked first in the number of documents issued, and the cooperation between institutions is dominated by the University of traditional Chinese medicine and its affiliated hospitals;Keyword cluster analysis shows that a large number of studies have been carried out in the field of etiology and pathogenesis, TCM compound, clinic and experiment. Conclusion: The research on the prevention and treatment of pulmonary interstitial fibrosis with TCM has a high degree of attention, but the cooperation network between the research authors and institutions needs to be strengthened. The research on the pathogenesis and improving the quality of life of patients is the trend of development in the future.展开更多

Then in situ hybridization was performed with PDGF-B chain cDNA probe and the results were quantitatively analyzed to measure the changes in PDGF-B chain mRNA expression in the lung tissue. The results showed that: (1) MP polymerase chain reaction (PCR) tests showed positive results in the bronchoalveolar lavage fluid (BALF ) from all of the MP-infected rats (n = 4) while they were all negative in BALF from the control animals (n = 4, P<0. 05) and in BALF from those rats both infected with MP and, at the same time, treated with erythromycin (n = 4, P<0. 05). Bacterial cultures of the bronchial and lung tissue were negative in all three groups. The observation under a transmission electron microscope indicated that the interalveo-lar septa were widened with increased amount of collagen in the MP-infected rats while there were no obvious abnormalities in the other two groups. (2) Strong positive expression of PDGF-B chain mRNA was found in the plasma of mono-cytes and macrophages located in the locally widened interalveolar septa and alveolar spaces in the lung tissue from the MP-infected animals with the integral optical densities being 37. 42 ±9. 05 (n = 4) which was significantly higher than the values of control group (0. 42 + 0. 08, n = 4, P<0. 01) and of the group with MP-infec-tion plus erythromycin treatment (1. 62 ± 0. 40, n = 4, P<0. 01). These results suggest that PDGF-BB may be involved in the process of the development of pulmonary interstitial fibrosis caused by the repeated MP-infection. It may be an important growth factor for mediating the roles of monocytes and macrophages to promote the aggregation and proliferation of fibroblasts which can then secrete collagen in large quantity in the pulmonary interstitium.展开更多

Wistar rats ( n =42) were randomly divided into normal group and emphysema model 1, 3, 5, 7, 15, 30 day groups ( n =6 in each group). The rat model of emphysema was induced by a single intratracheal instillation of papain. The results of immunohistochemistry SABC and in situ hybridization with bFGF probe were quantitatively analyzed to examine the changes of collagen Ⅰand collagen Ⅲ and bFGF mRNA expression in lung tissues and the percent of positive expression of bFGFmRNA in alveolar macrophages. The results were as follows: (1) In the emphysema model groups the optical densities of collagen Ⅰand collagen Ⅲ began to increase after 3 days, reached the highest at the 7 th day, and began to reduce at the 15 th day; (2) No expression of bFGFmRNA in pulmonary tissues was detectable in the normal group. The positive expression of bFGFmRNA was detectable in lung tissues one day after the intratracheal instillation of papain. The average optical densities reached the peak (41.895±7.017) at the 7th day, significantly higher than in the normal group (0.581±0.139, P <0.01). The positive expression of bFGFmRNA in lung tissues began to reduce at the 15th day; (3) Positive expression of bFGFmRNA in alveolar macrophages of instillation papain rats was detectable 3 days after the intratracheal instillation of papain, and reached the highest at the 7th day with the percent of positive expression of bFGF mRNA in alveolar macrophages being 70.13±11.21, higher than in the normal group (5.12±0.18, P <0.01); (4) The expression of bFGF mRNA in the lung tissues and macrophages was postively related with the changes in collagen Ⅰ and collagen Ⅲ ( P <0.01 or P <0.05) respectively. It was suggested that the up regulation of bFGF mRNA expression during the development of emphysema can lead pulmonary interstitial fibrosis, which may take part in the injury and repair and the lung tissue reconstruction.展开更多
