Objective:To evaluate the construction effect of famous doctor studio and the correlation among the acceptance indexes by analyzing the achievements of famous doctor studio in the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine.Methods:R software was used to count the relevant data of national famous medical studios approved from 2010 to 2018, and the advantages were analyzed by radar chart; Spearman correlation coefficient was calculated, and R software was used to draw the correlation heat map between the evaluation indexes; papers published by studio members during the construction period were retrieved, which were transformed into refworks format, imported into CiteSpace software to draw a visual knowledge map.Results:A total number of 506 articles were included in this study, involving 25 evaluation indexes and 22 national famous doctors' studios. The statistical analysis results showed that there was a significant positive correlation between the number of academic experience papers of famous and senior TCM experts published in core journals (V3) and the number of diagnosis and treatment schemes of dominant diseases (V1), and there was a significant negative correlation between 8 groups of indexes; Tinnitus, insomnia, premature ovarian failure, acupuncture and acupuncture therapy are research hotspots.Conclusions:When evaluating the construction effect of famous doctor studio, various indicators should be considered comprehensively, appropriately control of the number of members is helpful to improve the quality of talent training, and pay attention should be paid to experience exchange and thought collision during the training process.

Objective:To investigate the clinical and biological characteristics of relapsed childhood low-risk acute B lymphoblastic leukemia (B-ALL).Methods:The clinical and laboratory data of 34 children who admitted in Beijing Boren Hospital from July 2017 to July 2018 were retrospectively analyzed, and 127-339 mutations of hematological malignancy related genes were analyzed.Results:The median time from the diagnosis to the recurrence was 871 d (87-1 446 d). The recurrence at early stage and late stage had 26 cases (76%) and 8 cases (24%), respectively. The recurrence before maintenance treatment, during maintenance therapy and after withdrawal of chemotherapy had 3 cases (9%), 12 cases (35%) and 19 cases (56%) (13 cases relapsed within 1 year after withdrawal, 6 cases relapsed after withdrawal 1-2 years and no one relapsed after withdrawal 2 years). The sites of recurrence included bone marrow alone accounting for 26 cases (76%), both intramedullary and extramedullary disease (EMD) accounting for 6 cases (18%), EMD alone accounting for 2 cases (6%). Flow cytometry showed that 9 patients presented minimal residual disease (MRD)-positive (6 cases with one positive, 2 cases with twice positive and 1 case with 3 times positive), including 8 cases occurred at early stage and 1 case occurred at late stage; and the level of MRD was 0.02%-3.82%. Complex chromosomal karyotype appeared in 6 relapsed children with normal or hyperdiploid karyotype at first diagnosis. Hematological malignancy related gene mutation detection was made in 28 cases, and the results showed that each patient had at least one gene mutation, and 2 or more gene mutations were detected in 25 cases (89%). The high frequency of gene mutations were as follows: CREBBP (7 cases, 25%), NRAS (7 cases, 25%), KRAS(7 cases, 25%), TP53 (4 cases, 14%), and NT5C2 (4 cases, 14%).Conclusions:The recurrence of childhood low-risk B-ALL occurs mostly in the maintenance treatment or in two years of withdrawal of chemotherapy. Positive MRD after complete remission is likely to show the risk of early recurrence. The gene mutations after the poor prognosis in cancer cells may be related to the recurrence of childhood low-risk B-ALL, and the common gene mutations include CREBBP, RAS signaling pathways genes and TP53, NT5C2.

Objective:This study has investigated the value of detecting cerebrospinal fluid (CSF) MyD88L265P mutation and interleukin-10 (IL-10) levels in the prognosis of PCNSL.Methods:We retrospectively analyzed the clinical data, CSF characteristics (including cytology, cell counting, total protein, and the level of cytokine IL-10) and treatment process of 39 PCNSL patients newly diagnosed by surgery and pathology (18 males and 21 females, aged 40-73 years) from August 2013 to December 2016 in Hua Shan Hospital North. MyD88L265P mutation was detected by digital PCR in 39 paraffin-embedded tissues and 35 cerebrospinal fluid samples. Log-rank test was used for univariate analysis and Cox regression for multivariate analysis to establish the prognosis model of PCNSL which might be related to PCNSL first progress-free survival (PFS) and overall survival (OS).Results:The median age of the 39 PCNSL patients was 59 years old, with 30.8% (12/39) intraocular involvement. The mutation rate of MyD88L265P in tissues and cerebrospinal fluid was 74.4% (29/39) and 40.0% (14/35), respectively. 51.9% (14/27) patients were observed with MyD88L265P mutation in both tissues and CFS. Univariate analysis showed that intraocular involvement, high level of IL-10 in CFS (≥45 pg/ml), and MyD88L265P mutation in CFS are factors significantly influencing median progression-free survival (mPFS) of patients ( P<0.05). Patients with intraocular involvement had shorter OS than those without involvement which was statistically significant ( HR=6.5,95% CI 1.7-47.3, P<0.05). And multivariate analysis showed that intraocular involvement ( HR=2.4, 95% CI 1.3-7.8, P<0.05) and CFS MyD88L265P mutation ( HR=2.1, 95% CI 1.1-5.7, P<0.05) were independent prognostic factors for PFS. Conclusion:The presence of intraocular involvement and MyD88L265P mutation in CFS indicated poor prognosis of PCNSL patients. High CSF IL-10 level was not an independent factor affecting prognosis.

Objective: To explore the effect of C1q / tumor necrosis factor-related protein 9 ( CTRP9 ) on the expression of genes and proteins related to lipid metabolism of brown adipose tissue (BAT) in mice after cold stimulation． Methods : C57BL /6J male mice were injected with adenovirus Ad-GFP (control group) or Ad-CTRP9 ( experience group) into the scapular region and kept for 7 days．After cold stimulation at 4 ℃ for 10 hours，the expression levels of BAT marker genes and proteins were detected by real time PCR and Western blot. Results: Overexpression of CTRP9 induced by cold stimulation significantly increased the mRNA level of iodothyronine deiodinase 2 (Dio2) in BAT (P＜0. 01) ．Additionally，there was no significant difference in the expression of BAT marker genes ( UCP-1，PGC-1 α , PRDM16 and ARβ3) ，and liposynthesis and lipolysis related genes (PPARγ , HSL and ATGL) ．Uncoupling protein 1 (UCP-1) protein expression was upregualted in Ad-CTRP9 compared to the Ad-GFP control group ，while the expression of lipolysis related protein adipose triglyceride lipase ( ATGL) decreased significantly (P＜0. 05) ． Conclusion In cold environment，overexpression of CTRP9 promotes the accumulation of UCP-1 protein in BAT，upregulates the expression of thyroid hormone signal related gene Dio2，and inhibits triglyceride hydrolysis to maintain a constant body temperature.

To address the increasing need for detecting and validating protein biomarkers in clinical specimens, mass spectrometry (MS)-based targeted proteomic techniques, including the selected reaction monitoring (SRM), parallel reaction monitoring (PRM), and massively parallel data-independent acquisition (DIA), have been developed. For optimal performance, they require the fragment ion spectra of targeted peptides as prior knowledge. In this report, we describe a MS pipe-line and spectral resource to support targeted proteomics studies for human tissue samples. To build the spectral resource, we integrated common open-source MS computational tools to assemble a freely accessible computational workflow based on Docker. We then applied the workflow to gen-erate DPHL, a comprehensive DIA pan-human library, from 1096 data-dependent acquisition (DDA) MS raw files for 16 types of cancer samples. This extensive spectral resource was then applied to a proteomic study of 17 prostate cancer (PCa) patients. Thereafter, PRM validation was applied to a larger study of 57 PCa patients and the differential expression of three proteins in prostate tumor was validated. As a second application, the DPHL spectral resource was applied to a study consisting of plasma samples from 19 diffuse large B cell lymphoma (DLBCL) patients and 18 healthy control subjects. Differentially expressed proteins between DLBCL patients and healthy control subjects were detected by DIA-MS and confirmed by PRM. These data demonstrate that the DPHL supports DIA and PRM MS pipelines for robust protein biomarker discovery. DPHL is freely accessible at https://www.iprox.org/page/project.html?id=IPX0001400000.
