OBJECTIVETo study whether co-stimulatory molecule CD40 of alveolar macrophage (AM) participated in the occurrence and development of silicosis, and to explore the intervention of Yiqi Huoxue Decoction (YHD) in the fibrosis of silicosis patients.

METHODSTotally 46 silicosis inpatients and outpatients were recruited and randomly assigned to the Western treatment group (A) and the Chinese medicine (CM) treatment group (B), 23 in each group. Patients in Group A received routine symptomatic treatment such as anti-inflammation, phlegm resolving, anti-spasm, and asthma relief, and so on. Patients in Group B additionally took YHD, one dose daily for 14 successive days. Besides, another 18 patients with chronic cough and sense of laryngeal foreign bodies were recruited as the normal control group, who had no obvious lesion confirmed by bronchofi6roscope and clinical diagnosis of the lung. They were treated by symptomatic supporting treatment. The alveolar lavage fluid was collected from all patients and isolated, and AM cells were cultured. The level of CD40 mRNA was detected by RT-PCR. The expression of CD40 protein was detected by Western blot.

RESULTSCompared with the normal control group, expression levels of CD40 mRNA and CD40 protein significantly increased in Group A (P < 0.01). Compared with Group A, expression levels of CD40 mRNA and CD40 protein significantly decreased in Group B (P < 0.01).

CONCLUSIONSHighly expressed co-stimulatory molecule CD40 of AM might participate in pulmonary fibrosis. YHD could hinder its roles, inhibit the progression of fibrosis, thereby playing an interventional role of treatment.

This article firstly established a new efficient method for screening anti-osteoporosis ingredients, which used two-dimensional zebrafish model combined with hyphenated chromatographic techniques to evaluate anti-osteoporosis activities of epimedin A and its metabolite baohuoside I. Adult zebrafish was used for metabolism of epimedin A in 0.5% DMSO, and LC-MS was used for analysis of the metabolite, which was captured by HPLC, and prednisolone-induced osteoporosis model of zebrafish was used to evaluate the anti-osteoporotic activities of trace amounts of epimedin A and baohuoside I. The results indicated that epimedin A and baohuoside I can prevent prednisolone-induced osteoporosis in zebrafish. The developed method in this paper enables the separation, enrichment and analysis of micro-amount metabolite of epimedin A, and anti-osteoporosis activities in vivo of epimedin A and baohuoside I was simple and efficient screening resorting to zebrafish osteoporosis mode. This paper would provide new ideas and methods for a rapid and early discovery of anti-osteoporosis activities of micro-ingredients and its metabolite of traditional Chinese medicine.

BACKGROUND: There is no effective method to identify liver cancer stem cells until now, which has become one of the major challenges in this field. OBJECTIVE: To explore a more effective and suitable way for the identification of liver cancer stem cells in hepatocellular carcinoma cell lines. METHODS: Firstly, the single cell separation technique was used to obtain single cells, which were seeded into 96-wel plates one by one. Secondly, cell sublines derived from single cell colonies (tumorigenic colonies) were selected and obtained. At last, the cells from these clones were transplanted into the forelimb armpits of nude mice to observe the tumorigenic ability. RESULTS AND CONCLUSION: The number of holes of single cells obtained was 371 by the single cell separation technique, and the success rate was 96.4%. According to the growth of cell clone, tumorigenic colonies were selected to be transplanted to the forelimb armpits of nude mice, and the tumor formation rate of the colonies was 100%. The identification model of single-cell-transplant-tumorigenic-test for liver cancer stem cells is confirmed to be preliminarily established, which lays the technology and methodological basis for the follow-up research.
