This data article describes the"Typical Regional Activity Patterns"(TRAP)dataset,which is based on the Tackling Key Problems in Air Pollution Control Program.In order to explore the interaction between air pollution and physical activity,we collected activity patterns of 9,221 residents with different occupations and lifestyles for three consecutive days in typical regions(Jinan and Baoding)where air pollutant concentrations were higher than those in neighboring areas.The TRAP dataset consists of two aspects of information:demographic indicators(personal information,occupation,personal habits,and living situation)and physical activity pattern data(activity location and intensity);additionally,the exposure measures of physical activity patterns are included,which data users can match to various endpoints for their specific purpose.This dataset provides evidence for exploring the attributes of activity patterns of residents in northern China and for interdisciplinary researchers to develop strategies and measures for health education and health promotion.

Chronic pancreatitis (CP) is a progressive and irreversible fibroinflammatory disorder, accompanied by pancreatic exocrine insufficiency and dysregulated gut microbiota. Recently, accumulating evidence has supported a correlation between gut dysbiosis and CP development. However, whether gut microbiota dysbiosis contributes to CP pathogenesis remains unclear. Herein, an experimental CP was induced by repeated high-dose caerulein injections. The broad-spectrum antibiotics (ABX) and ABX targeting Gram-positive (G⁺) or Gram-negative bacteria (G^-) were applied to explore the specific roles of these bacteria. Gut dysbiosis was observed in both mice and in CP patients, which was accompanied by a sharply reduced abundance for short-chain fatty acids (SCFAs)-producers, especially G⁺ bacteria. Broad-spectrum ABX exacerbated the severity of CP, as evidenced by aggravated pancreatic fibrosis and gut dysbiosis, especially the depletion of SCFAs-producing G⁺ bacteria. Additionally, depletion of SCFAs-producing G⁺ bacteria rather than G^- bacteria intensified CP progression independent of TLR4, which was attenuated by supplementation with exogenous SCFAs. Finally, SCFAs modulated pancreatic fibrosis through inhibition of macrophage infiltration and M2 phenotype switching. The study supports a critical role for SCFAs-producing G⁺ bacteria in CP. Therefore, modulation of dietary-derived SCFAs or G⁺ SCFAs-producing bacteria may be considered a novel interventive approach for the management of CP.

Glioblastoma is carcinogenesis of glial cells in central nervous system and has the highest incidence among primary brain tumors. Brain metastasis, such as breast cancer and lung cancer, also leads to high mortality. The available medicines are limited due to blood-brain barrier. Abnormal activation of phosphatidylinositol 3-kinases (PI3K) signaling pathway is prevalent in glioblastoma and metastatic tumors. Here, we characterized a 2-amino-4-methylquinazoline derivative XH30 as a potent PI3K inhibitor with excellent anti-tumor activity against human glioblastoma. XH30 significantly repressed the proliferation of various brain cancer cells and decreased the phosphorylation of key proteins of PI3K signaling pathway, induced cell cycle arrest in G1 phase as well. Additionally, XH30 inhibited the migration of glioma cells and blocked the activation of PI3K pathway by interleukin-17A (IL-17A), which increased the migration of U87MG. Oral administration of XH30 significantly suppressed the tumor growth in both subcutaneous and orthotopic tumor models. XH30 also repressed tumor growth in brain metastasis models of lung cancers. Moreover, XH30 reduced IL-17A and its receptor IL-17RA in vivo. These results indicate that XH30 might be a potential therapeutic drug candidate for glioblastoma migration and brain metastasis.

Objective: To explore the association between inflammation activity of left atrial epicardial adipose tissue (LA-EAT) measured by ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography (¹⁸F-FDG PET/CT) and atrial fibrillation (AF). Methods: A total of 78 patients with AF, who underwent ¹⁸F-FDG PET/CT in the Nuclear Medicine Department of the Third Affiliated Hospital of Soochow University due to abnormally elevated levels of tumor indicators or malignant tumors from March 2018 to December 2019, were enrolled in this retrospective study. According to the examination date of PET/CT and basic characteristics of AF patients (gender, age), a 1∶1 propensity score matching was used to enroll a non-AF control group (78 patients). The maximum standard uptake value of left atrial epicardial tissue (LA-EAT FDG SUV_max) and total EAT volume (V-EAT) were measured by ¹⁸F-FDG PET/CT. Left ventricular ejection fraction (LVEF) and left atrial diameter (LAD) were obtained by echocardiography. Blood lipids and biomarkers of inflammation were measured. The differences of clinical data and EAT-related indicators were compared between the AF group and control group. Logistic multivariate regression analysis was used to determine the related factors of AF. Then the receiver operating characteristic (ROC) curve was used to determine the cutoff value of LA-EAT FDG SUV_max on the diagnosis of AF. Univariate and multivariate logistic regression analysis were used to analyze the relationship between the increase of LA-EAT FDG SUV_max and AF. Results: The age was (66.9±10.2) years and there were 55 males (70.5%) in the AF group. The age was (66.9±8.0) years, and there were 52 males (66.7%) in the control group (both P>0.05). The LAD ((44.2±5.8) mm vs. (35.4±4.4) mm), V-EAT ((122.1±42.0) cm³ vs. (91.6±34.5) cm³), and LA-EAT FDG SUV_max ((1.6±0.3) vs. (1.4±0.2)) values were significantly higher, while LVEF ((60.1±4.7)% vs. (63.9±2.9)%) was lower in the AF group than in the control group (P all<0.001). Multivariate logistic regression analysis showed that LAD (OR=1.340, 95%CI 1.195-1.502), V-EAT (OR=1.016, 95%CI 1.001-1.031), and LA-EAT FDG SUV_max (OR=1.375, 95%CI 1.095-1.723) were positively correlated with AF, LVEF (OR=0.781, 95%CI 0.659-0.926) was negatively correlated with AF(P all<0.05). The area under the ROC curve of LA-EAT FDG SUV_max for diagnosis of AF was 0.680 (95%CI 0.597-0.764, P<0.001), and the best cut-off value was 1.415 with a sensitivity of 65.4% and specificity of 61.5%. After adjusting for high-density lipoprotein cholesterol, LVEF, LAD and V-EAT, LA-EAT FDG SUV_max≥1.415 was independently associated with AF (OR=2.982, 95%CI 1.122-7.926, P=0.010). Conclusions: The inflammatory activity of LA-EAT measured by ¹⁸F-FDG PET/CT is an independent risk factor of AF, and the increased inflammatory activity of LA-EAT is positively correlated with AF.

Objective: To study the efficacy, safety and long-term outcomes of integrated strategy of bortezomib-based induction regimens followed by autologous hematopoietic stem cell (ASCT) and maintenance therapy in Chinese multiple myeloma (MM) patients. Methods: 200 MM patients receiving integrated strategy of bortezomib--based induction regimens followed by ASCT and maintenance therapy were retrospectively and prospectively analyzed from December 1. 2006 to April 30. 2018. Results: The complete remission rates (CR) and better than very good partial remission rates (VGPR) after induction therapy, transplantation and maintenance therapy were respectively 31% and 75.5%, 51.8% and 87.7%,73.6% and 93.4%. There was no difference between 4 cycles and more than 5 cycles induction chemotherapy. The negative rate of MRD detection by flow cytometry was 17.6% and 38.2% respectively after induction and 3 months after transplantation. The negative rate of MRD gradually increased during the maintenance therapy. The success rate of high dose CTX combined with G-CSF mobilization was 95.5% and transplantation related mortality (TRM) was zero. The median time to progress (TTP) was 75.3 months and the median overall survival (OS) was 99.5 months. TTP of patients obtaining CR and negative MRD after induction were longer that those of no CR and positive MRD. TTP and OS of patients receiving triple-drug induction and ASCT in early stage were longer than those of double-drug induction and ASCT in late stage. LDH≥240 U/L, high risk cytogenetics, ISS II+III stage and HBsAg positive were prognostic factors at diagnosis. However, only MRD and high risk cytogenetics were independent prognostic factors after transplantation and maintenance therapy. The clinical characteristics of patients of TTP ≥6 years were listed below: light-chain type M protein, ISS I stage, normal level of hemoglobin and platelet, normal LDH, HBsAg negative, chromosome 17p-negative, good response and sustained good response. Conclusions: Integrated strategy of bortezomib-based induction regimens followed by ASCT and maintenance therapy can significantly improve the short-term and long-term efficacy. The prognostic factors of TTP in different disease stages were different. Response to treatment, especially MRD, played a more important role in prognostic factors.

Objective: To investigate the incidence and clinical features to probe the risk factors of hemorrhagic cystitis (HC) in children and adolescents with hematological diseases post haplo-hematopoietic stem cell transplantation (haplo-HSCT) . Methods: Medical records of 62 children and 27 adolescents with hematological diseases treated with haplo-HSCT between 2015 and 2016 were analyzed. Results: Of 89 cases (56 boys and 33 girls) , 44 patients were diagnosed with ALL, 33 AML, 3 AHL and 9 MDS. HC occurred in 32 of the 89 patients with an incidence of 36%, including 6 with grade Ⅰ, 16 with grade Ⅱ, 8 with grade Ⅲ, 2 with grade Ⅳ HC, respectively. The median time of HC onset was 25 days (range 2-55 days) after haplo-HSCT with the median duration as 19 days (range 3-95 days) , all of them were cured. The incidence of HC was lower in the group of children than that in the group of adolescents (27.4% vs 55.6%, χ(2)=6.466, P<0.05) , and the incidence of HC was higher in the group of patients who were ≥5 years old than that in the group of patients who were <5 years old (0 vs 34%, χ(2)=4.043, P<0.05) . Conclusion: HC is one of common complications in children and adolescents with hematological diseases post haplo-HSCT, older age was associated with increased mortality.

OBJECTIVETo investigate the potential signaling pathway that regulates the proliferation of human CD34cells stimulated by prostaglandin E2 receptor 4 agonist (EP4A) in vitro.

METHODSTwenty samples of peripheral blood containing stem cells were collected from the G-CSF mobilized healthy donors in our department of hematology. Human CD34cells were isolated by magnetic activated cell sorting (MACS) microbeads kit. The Cell Counting Kit-8 (CCK8) assay was used to determine the optimal concentration and time of EP4A to promote human CD34cell proliferation in vitro. Under the optimal condition, quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect mRNA level of β-catenin, and Western blot was used to assay protein expression of β-catenin and P-GSK-3β in human CD34cells treated with EP4A.

RESULTSCulturing with 10 µmol/L EP4A for 72 h, it was found that EP4A promoted human CD34cell proliferation significantly, and the proliferation rate of human CD34cells was 1.36 times higher than that of the control(P=0.002). Under the optimal condition, it was also found that EP4A enhanced the β-catenin expression at both mRNA and protein levels, and up-regulated phosphorylation of GSK-3β in human CD34cells, but these effects could be inhibited by the EP4A antagonist EP4AA.

CONCLUSIONEP4A can enhance human CD34cell proliferation in vitro by activating Wnt/β-catenin signaling pathway.

Chemical constituents in extract of Scrophulariae Radix and their metabolites in rat plasma after oral administration were identified by HPLC-LTQ-Orbitrap. Samples were separated by a Venusil MP C₁₈ column using a binary gradient elution. The information on the total ion chromatogram, the extraction chromatogram and the mass spectrogram in a negative mode were synthetically analyzed by comparing the retention time, MS and MS/MS spectra with literature data and some of reference standards to conduct a qualitative study on constituents of Radix Scrophulariae extract in vivo and in vitro. Totally 37 compounds from Scrophularia ningpoensis extract were detected including 12 iridoid glycosides, 20 phenylpropanoids and 5 unknown compounds. In vivo, harpagide, harpagoside and angoroside C were confirmed to enter into the blood in prototype forms. Besides, another 2 prototype compounds and 2 metabolites were detected in rat plasma after oral administration of S. ningpoensis extract. The results are beneficial for the determination of bioactive substances of S. ningpoensis and significant for further studies on S. ningpoensis.

ObjectiveTo explore the expression of long noncoding RNA (lncRNA) LINC01358 in prostate cancer (PCa) and its effect on the proliferation and migration of PCa cells.

METHODSThe lncRNA array was used to screen differentially expressed lncRNAs in PCa and the corresponding carcinoma-adjacent normal tissues from 3 patients. The expressions of LINC01358 in the primary PCa, metastatic PCa, and carcinoma-adjacent tissues were compared using the PCa dataset of the Memorial Sloan Kettering Cancer Center (MSKCC). The data obtained were validated by determining the expression of LINC01358 in the PCa and carcinoma-adjacent tissues of another 10 patients by quantitative real time PCR (qRT-PCR). The effects of lncRNA LINC01358 on the proliferation of DU145 cells and migration of PCa cells were detected by MTT and Transwell assay, respectively.

RESULTSTotally, 79 differentially expressed lncRNAs in the lncRNA array, 36 highly and the other 43 lowly expressed in the PCa tissue. LINC01358 was up-regulated in the cancerous tissue. According to the MSKCC data, the LINC01358 expression was markedly higher in metastatic PCa (5.81±0.19, n = 19) and primary PCa (5.47±0.04, n = 131) than in the PCa-adjacent tissue (5.15±0.07, n = 29) and significantly correlated with postoperative biochemical relapse of the malignancy (P<0.05). qRT-PCR indicated a remarkably higher expression of LINC01358 in the PCa than in the carcinoma-adjacent tissue (6.02±1.12 vs 3.21±0.21, P<0.05). Transfection of the DU145 cells with siRNA significantly decreased the level of LINC01358 and inhibited the proliferation and migration of the PCa cells.

CONCLUSIONSLINC01358 is highly expressed in the PCa tissue and knockdown of LINC01358 may inhibit the proliferation and migration of PCa cells. LncRNA LINC01358 may be involved in the development and progression of PCa and become an index for the early diagnosis as well as a new target for the gene therapy of the malignancy.
