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.

OBJECTIVES:
Restoration of blood circulation within "time window" is the principal treating goal for treating acute ischemic stroke. Previous studies revealed that delayed recanalization might cause serious ischemia/reperfusion injury. However, plenty of evidences showed delayed recanalization improved neurological outcomes in acute ischemic stroke. This study aims to explore the role of delayed recanalization on blood-brain barrier (BBB) in the penumbra (surrounding ischemic core) and neurological outcomes after middle cerebral artery occlusion (MCAO).
METHODS:
Recanalization was performed on the 3rd day after MCAO. BBB disruption was tested by Western blotting, Evans blue dye, and immunofluorescence staining. Infarct volume and neurological outcomes were evaluated on the 7th day after MCAO. The expression of fibroblast growth factor 21 (FGF21), fibroblast growth factor receptor 1 (FGFR1), phosphatidylinositol-3-kinase (PI3K), and serine/threonine kinase (Akt) in the penumbra were observed by immunofluorescence staining and/or Western blotting.
RESULTS:
The extraversion of Evans blue, IgG, and albumin increased surrounding ischemic core after MCAO, but significantly decreased after recanalization. The expression of Claudin-5, Occludin, and zona occludens 1 (ZO-1) decreased surrounding ischemic core after MCAO, but significantly increased after recanalization. Infarct volume reduced and neurological outcomes improved following recanalization (on the 7th day after MCAO). The expressions of Claudin-5, Occludin, and ZO-1 decreased surrounding ischemic core following MCAO, which were up-regulated corresponding to the increases of FGF21, p-FGFR1, PI3K, and p-Akt after recanalization. Intra-cerebroventricular injection of FGFR1 inhibitor SU5402 down-regulated the expression of PI3K, p-Akt, Occludin, Claudin-5, and ZO-1 in the penumbra, which weakened the beneficial effects of recanalization on neurological outcomes after MCAO.
CONCLUSIONS
Delayed recanalization on the 3rd day after MCAO increases endogenous FGF21 in the penumbra and activates FGFR1/PI3K/Akt pathway, which attenuates BBB disruption in the penumbra and improves neurobehavior in MCAO rats.

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.

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.

PURPOSE: To examine the usefulness of various receptor tyrosine kinase expressions as prognostic markers and therapeutic targets in muscle invasive urothelial cancer (UC) patients. MATERIALS AND METHODS: We retrospectively analyzed the data of 98 patients with muscle invasive UC who underwent radical cystectomy between 2005 and 2010 in Yonsei Cancer Center. Using formalin fixed paraffin embedded tissues of primary tumors, immunohistochemical staining was done for human epidermal growth factor receptor 2 (HER2), fibroblast growth factor receptor 1 (FGFR1), and fibroblast growth factor receptor 3 (FGFR3). RESULTS: There were 41 (41.8%), 44 (44.9%), and 14 (14.2%) patients who have over-expressed HER2, FGFR1, and FGFR3, respectively. In univariate analysis, significantly shorter median time to recurrence (TTR) (12.9 months vs. 49.0 months; p=0.008) and overall survival (OS) (22.3 months vs. 52.7 months; p=0.006) was found in patients with FGFR1 overexpression. By contrast, there was no difference in TTR or OS according to the HER2 and FGFR3 expression status. FGFR1 remained as a significant prognostic factor for OS with hazard ratio of 2.23 (95% confidence interval: 1.27-3.90, p=0.006) in multivariate analysis. CONCLUSION: Our result showed that FGFR1 expression, but not FGFR3, is an adverse prognostic factor in muscle invasive UC patients after radical cystectomy. FGFR1 might be feasible for prognosis prediction and a potential therapeutic target after thorough validation in muscle invasive UC.

OBJECTIVETo observe the expression levels of hippocampal vascular endothelial growth factor (VEGF), fms-like tyrosine kinase-1 (flt-1), basic fibroblast growth factor (bFGF), and basic fibroblast growth factor receptor (bFGF-r) in vascular dementia (VD) rats, thus studying the angiogenesis mechanism of moxibustion in VD.
METHODSSixty male elderly Wistar rats were selected. The VD rat model was prepared by bilateral carotid artery occlusion and reperfusion of sodium nitroprusside injection. The model rats were divided into 3 groups by the random digit table, i. e., the moxibustion group, the Western medicine group, and the model group. A sham-operation control group was also set up. In the moxibustion group rats was acupunctured at Baihui (GV20), Shenting (GV14), and Dazhui (GV24). Aniracetam was given to rats in the Western medicine group by gastrogavage for 2 therapeutic courses, 15 days as one course. The learning and memory results were observed by the neuroethological score in combination of step-down avoidance test before treatment and by the end of the 2nd course respectively. The expression levels of hippocampal VEGF, flt-1, bFGF, and bFGF-r of all rats were detected using immunohistochemical assay.
RESULTSAfter 2 courses of treatment, statistical difference existed in the latent period, the error times, and the neuroethological score in the moxibustion group and the Western medicine group when compared with the model group (P < 0.01, P < 0.05). Statistical difference existed in the latent period and the neuroethological score between the moxibustion group and the Western medicine group (P < 0.05), which indicated that moxibustion and Western medicine showed significant effects in improving the latent period, decreasing the error times and the neuroethological score. Better results were obtained in the moxibustion group than in the Western medicine group (P < 0.01, P < 0.05). Statistical difference of the average grey level (AGL) of hippocampal VEGF, flt-1, and bFGF existed in the moxibustion group and the Western medicine group when compared with the model group. Statistical difference of the bFGF-r expression existed only between the moxibustion group and the model group. Statistical difference of the VEGF and flt-1 expressions existed between the moxibustion group and the Western medicine group (P < 0.05).
CONCLUSIONSMoxibustion showed confirmative effects in improving the behavioral score and memory performance in VD rats. Its mechanisms might lie in that moxibustion regulated and controlled the expression levels of hippocampal VEGF, flt-1, bFGF, and bFGF-r in VD rats. Particularly it up-regulated the expression levels of key factors VEGF and flt-1, promoted the angiogenesis in the vital parts, and ultimately stimulated the repairing mechanisms of cerebral nerve injury.

The study investigated the effects of adenovirus-mediated gene transfection of basic fibroblast growth factor (bFGF), bFGF combined with interleukin-1 receptor antagonist protein (IL-Ra) and/or insulin-like growth factor-1 (IGF-1) both in human osteoarthritis (OA) chondrocytes and rabbits OA model. Human OA chondrocytes were delivered by adenovirus-mediated bFGF, IL-Ra and IGF-1 vectors, respectively. Chondrocyte proliferation, glycosaminoglycan (GAG) content, expression of type II collagen, ADAMTS-5, MMP-13, MMP-3 and TIMP-1 were determined. Rabbit OA model was induced by anterior cruciate ligament transaction (ACLT) in knees. Adenoviral vectors encoding human bFGF, IL-Ra and IGF-1 were injected intraarticularly into the knee joints after ACLT. The effects of adenovirus- mediated gene transfection on rabbit OA were evaluated. In vitro, the transfected genes were expressed in cell supernatant of human OA chondrocytes. AdbFGF group significantly promoted chondrocyte proliferation, and increased GAG and type II collagen synthesis than in the OA group. As two or three genes were transfected in different combinations, there was significant enhancement on the GAG content, type II collagen synthesis, and TIMP-1 levels, while ADAMTS-5, MMP-13, and MMP-3 levels were reduced. In vivo, the transfected genes were expressed in synovial fluid of rabbits. Intraarticular delivery of bFGF enhanced the expression of type II collagen in cartilage and decreased cartilage Mankin score compared with the OA control group (P = 0.047; P < 0.01, respectively). Multiple-gene transfection in different combinations showed better results than bFGF transfection alone. This study suggests that bFGF gene transfection is effective in treating experimental OA. Multiple gene transfection has better biologic effects on OA.
