This study aimed to explore the molecular mechanism of Juanbi Qianggu Formula(JBQGF), an empirical formula formulated by the prestigious doctor in traditional Chinese medicine, in the treatment of rheumatoid arthritis based on network pharmacology and cell function experiments. The main active components and targets of JBQGF were obtained through Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and Encyclopedia of Traditional Chinese Medicine(ETCM), and the core targets underwent functional enrichment analysis and signaling pathway analysis. Cytoscape 3.6.0 was used to construct a visualized "active component-target-signaling pathway" network of JBQGF. After screening, nine potential pathways of JBQGF were obtained, mainly including G protein-coupled receptor signaling pathway and tyrosine kinase receptor signaling pathway. As previously indicated, the fibroblast growth factor receptor 1(FGFR1) signaling pathway was highly activated in active fibroblast-like synoviocytes(FLS) in rheumatoid arthritis, and cell and animal experiments demonstrated that inhibition of the FGFR1 signaling pathway could significantly reduce joint inflammation and joint destruction in collagen-induced arthritis(CIA) rats. In terms of the tyrosine kinase receptor signal transduction pathway, the analysis of its target genes revealed that FGFR1 might be a potential target of JBQGF for rheumatoid arthritis treatment. The biological effect of JBQGF by inhibiting FGFR1 phosphorylation was preliminarily verified by Western blot, Transwell invasion assay, and pannus erosion assay, thereby inhibiting matrix metalloproteinase 2(MMP2) and receptor activator of nuclear factor-κB ligand(RANKL) and suppressing the invasion of fibroblasts in rheumatoid arthritis and erosive effect of pannus bone. This study provides ideas for searching potential targets of rheumatoid arthritis treatment and TCM drugs through network pharmacology.

OBJECTIVE: To deeply understand the clinical manifestation, laboratory examination characteristics, diagnosis and treatment of an eight p11 myeloproliferative syndrome (EMS) with rare phenotypes. METHODS: The clinical and laboratory characteristics and the process of allogeneic hematopoietic stem cell transplantation (allo-HSCT) were summarized in 1 rare EMS case involving T/B/myeloid cells. Meanwhile, 2 similar cases in the previous literature were also discussed. RESULTS: The bone marrow examination indicated that the patient with B-cell acute lymphocytic leukemia. The lymph node biopsy showed that the patient was T lymphoblastic/myeloid lymphoma. The 8p11 abnormality was found by the examination of bone marrow chromosomes. The RT-PCR examination showed that the BCR-ABL fused gene was negtive. The FGFR1 breakage was found by using the FISH with FGFR1 probe in lymph node. The Mutation of FMNL3, NBPF1 and RUNX1 genes was found by using the whole exome sequencing. The patient received allo-HSCT under CR2. By the follow-up till to September 2019, the patient survived without the above-mentioned disease. CONCLUSION EMS manifest as neoplasms involving T-lineage, B-lineage, and myeloid-lineage simultaneously is extremely rare. Although the FGFR1 gene-targeted therapy can be conducted, allo-HSCT should be actively considered.

OBJECTIVE: To study the potential significance and clinical application of FGFR1 gene abnormality in the diagnosis, clinical features, pathological mechanism and treatment in hematological tumors. METHODS: Clinical data of total of 29 patient with chromosome of 8 short arm (8P) abnormality who had more comprehensive medical history from 2013 to 2018 were collected. The karyotype analysis of bone marrow chromosomes in patients was carried out by using chromosome R band banding technique. FGFR1 gene was detected by using fluorescence in situ hybridization (FISH). RESULTS: Seven cases of FGFR1 gene abnormalities were decteted, including 3 cases of FGFR1 gene amplification, 2 cases of translocation, and 2 cases of deletion. Five patients with FGFR1 gene amplification or deletion not accompaned with eosinophilia, moreover the chromosome was a complex karyotype with poor prognosis; Two cases of FGFR1 gene translocation were non-complex chromosomal translocation and one of which survived for 6 years after bone marrow transplantation, the other chromosome karyotype showed no rearrangement of 8 short arm. However, FGFR1 gene rearrangement was confirmed by FISH analysis, which was a rare insertional translocation. CONCLUSION FGFR1 gene amplification or deletion often occur in cases with complex karyotype, which not accompany eosinophilia, moreover have poor prognosis. The patients with FGFR1 gene translocation accompany eosinophilia which is consistent with the clinical characteristics of myeloid / lymphoid neoplasms with FGFR1 abnormality. Karyotype analysis combined with FISH method can improve the detection of abnormal clones.

Objective: To investigate the clinic-pathological features, diagnosis and treatment of 8p11 myeloproliferative syndrome (EMS) . Methods: Five patients diagnosed as EMS from Jan 2014 to May 2018 at Blood Disease Hospital, Chinese Academy of Medical Sciences were enrolled. The clinical manifestations, laboratory characteristics, treatment and outcome of these patients were summarized. Results: The peripheral blood leukocyte count of 5 patients with EMS increased significantly, accompanied with an elevated absolute eosinophils value (the average as 18.89×10(9)/L) . The hypercellularity of myeloid cells was common in bone marrow, always with the elevated proportion of eosinophils (the average as 17.24%) , but less than 5% of blast cells. The chromosome karyotype of the 5 cases differed from each other, but presenting with the same rearrangement of FGFR1 gene by fluorescence in situ hybridization technology. The average interval between onset and diagnosis was 4.8 months with a median survival of only 14 months. Conclusion: EMS was a rare hematologic malignancy with poor prognosis and short survival. It was commonly to be misdiagnosed. Analysis of cytogenetics and molecular biology were helpful for early diagnosis.

BACKGROUND: The methods of detection for recurrence and metastasis in patients with non-small cell lung cancer (NSCLC) have hysteresis and one-sidedness. This study summarizes the relationship between the circulating tumor cell (CTC) in peripheral blood, expression of fibroblast growth factor receptor 1 (FGFR1) and clinic pathological features in 30 patients with NSCLC so as to provide new ideas for the detection of tumor recurrence and metastasis. METHODS: To analyze the clinical data and CTC detection data of 30 cases of NSCLC in Department of Thoracic Surgery, Peking Union Medical College Hospital from November 2016 to June 2017. RESULTS: Data analysis showed that the positive rate of CTC in peripheral blood was remarkably correlated with the smoking history (P=0.016). There was no significant correlation among the pathological type and CTC positive rate and the expression of FGFR1 (P=0.202, P=0.806). There was no significant difference in the expression of FGFR1 in different type CTC cells (P=0.094). CONCLUSIONS The positive rate of CTC was significantly correlated with the smoking history of patients with NSCLC. There was no significant difference in CTC classification and FGFR1 expression in different pathological types of NSCLC. There was no significant difference in the expression of FGFR1 between different types of CTCs. We look forward to a larger sample size and inclusion of follow-up data to arrive at more clinically relevant conclusions about CTC and FGFR1 gene expression.

OBJECTIVETo review the prevalence and prognostic significance of fibroblast growth factor receptor 1 (FGFR1) amplification and to establish an association between FGFR1 amplification and the clinical characteristics of nonsmall cell lung cancer (NSCLC).

DATA SOURCESWe searched PubMed for English-language studies published between January 2010 and May 2016.

STUDY SELECTIONWe included all relevant articles, with no limitation of study design.

RESULTSFGFR1 amplification was reported in 8.7-20.0% of NSCLC cases and was significantly more frequent in squamous cell carcinomas (SCCs) (9.7-28.3%) than in adenocarcinomas (ADCs) (0-15.0%). The rates of FGFR1 amplification were as follows: males, 13.9-22.1%; females, 0-20.1%; Stage I NSCLC, 9.3-24.1%; Stage II NSCLC, 12.9-25.0%; Stage III NSCLC, 8.2-19.5%; Stage IV NSCLC, 0-12.5%; current smokers, 13.3-29.0%; former smokers, 2.5-23.0%; and nonsmokers, 0-22.2%. Overall survival was 43.9-70.8 months in patients with FGFR1 amplification and 42.4-115.0 months in patients with no FGFR1 amplification; disease-free survival was 22.5-58.5 months and 52.4-94.6 months, respectively.

CONCLUSIONSFGFR1 amplification is more frequent in SCCs than in ADCs. The association between FGFR1 amplification and clinical characteristics (gender, smoking status, and disease stage) and the prognostic significance of FGFR1 amplification in NSCLC remain controversial.

OBJECTIVE To explore the clinical and laboratory features of a patient with 8p11 myeloproliferative syndrome (EMS) and CEP110-FGFR1 fusion. METHODS Combined bone marrow cytology, fluorescence in situ hybridization, fusion gene detection was used to analyze the patient. RESULTS Clinically, the patient had many features similar to those with chronic myelomonocytic leukemia, which included hyperleukocytosis, marked eosinophilia, monocytosis, myeloid hyperplasia and hyperplasia. Fluorescence in situ hybridization analysis for FGFR1 gene rearrangement was positive. Further study of the mRNA also confirmed an in-frame fusion between exon 38 of the CEP110 gene and exon 9 of FGFR1 gene. CONCLUSION EMS with CEP110-FGFR1 fusion is a very rare and distinct myeloproliferative neoplasm. FISH and molecular studies may improve its diagnosis.
