RESUMO
Based on survey data conducted in Guangzhou in 2021, this study employs canonical correlation analysis (CCA) to evaluate the relationship between neighborhood green space, residents' green space use behavior, and their mental health. The results show that compared with the objectively measured accessibility, residents' subjective perceived accessibility of neighborhood green space plays a greater role in promoting green space use behavior and mental health. Meanwhile, the plant diversity, safety, and the number of recreational facilities in a green space can promote the frequency of green space use, improve residents' mental health status and reduce their perceived stress. Although perceived accessibility is more related to green space use behavior than green space quality indicators, green space safety and recreational facilities have many more benefits on mental health than perceived accessibility. In addition, residents' green space use behavior, especially green space visit frequency, can promote mental health and reduce perceived stress.

The translocation t(8;9) produces the fusion gene PCM1-JAK2, resulting in the continuous activation of the JAK2 tyrosine kinase. Myelodysplastic/myeloproliferative neoplasms are the most common disease with t(8;9)/PCM1-JAK2. Individuals with this abnormality have similar features, and JAK2 kinase inhibitor (ruxolitinib) is an effective treatment of the condition. The long-term remission results of ruxolitinib are varied. It is important to determine the response to ruxolitinib. Here, we describe a patient who has been diagnosed with eosinophilia-associated myeloproliferative neoplasm with t(8;9)(p21;p24). This patient has achieved sustained response for >1 year since the administration of ruxolitinib.

PURPOSE: This study utilized intelligent devices to remotely monitor patients with chronic obstructive pulmonary disease (COPD), aiming to construct and evaluate machine learning (ML) models that predict the probability of acute exacerbations of COPD (AECOPD). METHODS: Patients diagnosed with COPD Group C/D at our hospital between March 2019 and June 2021 were enrolled in this study. The diagnosis of COPD Group C/D and AECOPD was based on the GOLD 2018 guidelines. We developed a series of machine learning (ML)-based models, including XGBoost, LightGBM, and CatBoost, to predict AECOPD events. These models utilized data collected from portable spirometers and electronic stethoscopes within a five-day time window. The area under the ROC curve (AUC) was used to assess the effectiveness of the models. RESULTS: A total of 66 patients were enrolled in COPD groups C/D, with 32 in group C and 34 in group D. Using observational data within a five-day time window, the ML models effectively predict AECOPD events, achieving high AUC scores. Among these models, the CatBoost model exhibited superior performance, boasting the highest AUC score (0.9721, 95 % CI: 0.9623-0.9810). Notably, the boosting tree methods significantly outperformed the time-series based methods, thanks to our feature engineering efforts. A post-hoc analysis of the CatBoost model reveals that features extracted from the electronic stethoscope (e.g., max/min vibration energy) hold more importance than those from the portable spirometer. CONCLUSIONS: The tree-based boosting models prove to be effective in predicting AECOPD events in our study. Consequently, these models have the potential to enhance remote monitoring, enable early risk assessment, and inform treatment decisions for homebound patients with chronic COPD.

BACKGROUND: Semaphorin 3A (Sema3A) is a member of neural guidance factor family well-known for inducing the collapse of nerve cell growth cone and regulating nerve redistribution. It also has been characterized as an immunoregulatory and tumor promoting factor. Our previous study showed that Sema3A was involved in the regulation of sympathetic innervation and neuropathic pain of endometriosis. Nevertheless, the role of Sema3A in the development of endometriosis and its potential upstreaming factor are still not clear. METHODS: Histology experiments were carried to detect the expression of Sema3A, hypoxia -inducible factor 1α (HIF-1α) and the distribution of macrophages. Cell experiments were used to explore the effect of Sema3A on the proliferation and migration of endometrial stromal cells (ESCs) and to confirm the regulatory action of HIF-1α on Sema3A. In vivo experiments were carried out to explore the role of Sema3A on the development of endometriosis. RESULTS: Sema3A was highly expressed in endometriotic lesions and could enhanced the proliferation and migration abilities of ESCs. Aberrant macrophage distribution was found in endometriotic lesions. Sema3A also promoted the differentiation of monocytes into anti-inflammatory macrophages, so indirectly mediating the proliferation and migration of ESCs. Hypoxic microenvironment induced Sema3A mRNA and protein expression in ESCs via HIF-1α. Administration of Sema3A promoted the development of endometriosis in a mouse model. CONCLUSIONS: Sema3A, which is regulated by HIF-1α, is a promoting factor for the development of endometriosis. Targeting Sema3A may be a potential treatment strategy to control endometriotic lesions.

Hydrogen therapy shows great promise as a versatile treatment method for diseases associated with the overexpression of reactive oxygen and nitrogen species (RONS). However, developing an advanced hydrogen therapy platform that integrates controllable hydrogen release, efficient RONS elimination, and biodegradability remains a giant technical challenge. In this study, we demonstrate for the first time that the tungsten bronze phase H0.53WO3 (HWO) is an exceptionally ideal hydrogen carrier, with salient features including temperature-dependent highly-reductive atomic hydrogen release and broad-spectrum RONS scavenging capability distinct from that of molecular hydrogen. Moreover, its unique pH-responsive biodegradability ensures post-therapeutic clearance at pathological sites. Treatment with HWO of diabetic wounds in an animal model indicates that the solid-state atomic H promotes vascular formation by activating M2-type macrophage polarization and anti-inflammatory cytokine production, resulting in acceleration of chronic wound healing. Our findings significantly expand the basic categories of hydrogen therapeutic materials and pave the way for investigating more physical forms of hydrogen species as efficient RONS scavengers for clinical disease treatment.
RESUMO
OBJECTIVE: To explore the role of gut dysbiosis-derived ß-glucuronidase (GUSB) in the development of endometriosis (EMs). DESIGN: 16S rRNA sequencing of stool samples from women with (n = 35) or without (n = 30) endometriosis and from a mouse model was conducted to assess gut microbiome changes and identify molecular factors influencing the development of endometriosis. Experiments in vivo in an endometriosis C57BL6 mouse model and in vitro verified the level of GUSB and its role in the development of EMs. SETTING: Department of Obstetrics and Gynecology, The First Affiliated Hospital of Sun Yat-sen University; Guangdong Provincial Clinical Research Center for Obstetrical and Gynecological Diseases. PATIENT(S): Women of reproductive age with a histological diagnosis of endometriosis were enrolled in the endometriosis group (n = 35) and infertile or healthy age-matched women who had undergone a gynecological or radiological examination in the control group (n = 30). Fecal and blood samples were taken the day before surgery. Paraffin-embedded sections from 50 bowel endometriotic lesions, 50 uterosacral lesions, 50 samples without lesions, and 50 normal endometria were collected. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Changes in the gut microbiome of patients with EMs and mice and the effect of ß-glucuronidase on the proliferation and invasion of endometrial stromal cells and the development of endometriotic lesions were assessed. RESULT(S): No difference in α and ß diversity was found between patients with EMs and controls. Immunohistochemistry analysis showed higher ß-glucuronidase expression in bowel lesions and uterosacral ligament lesions than in the normal endometrium (p<0.01). ß-Glucuronidase promoted the proliferation and migration of endometrial stromal cells during cell counting kit-8, Transwell, and wound-healing assays. Macrophage levels, especially M2, were higher in bowel lesions and uterosacral ligament lesions than in controls, and ß-glucuronidase promoted the M0 to M2 transition. Medium conditioned by ß-glucuronidase-treated macrophages promoted endometrial stromal cell proliferation and migration. ß-Glucuronidase increased the number and volume of endometriotic lesions and number of macrophages present in lesions in the mouse EMs model. CONCLUSION(S): This ß-Glucuronidase promoted EMs development directly or indirectly by causing macrophage dysfunction. The characterization of the pathogenic role of ß-glucuronidase in EMs has potential therapeutic implications.

BACKGROUND: Decitabine are used in the treatment of myelodysplastic syndrome (MDS), but none trials reported overall survival improvement. METHODS: High-risk MDS and MDS transformed AML (sAML) patients (IPSS-R > 4.5, age above 60 years) in 6 medical centers of China were treated and compared a new regimen (decitabine with CEG) consisted of low dose decitabine (15 mg/m2, days 1-3), low dose etoposide (30 mg/m2, days 4,6,8,10,12), cytarabine (10 mg/m2 per day, days 4-12) and granulocyte colony-stimulating factor (G-CSF, 5ug/kg, adjusted by patients' WBC level, 12 hours prior to decitabine administration) with decitabine alone. The endpoints were death and disease progression. RESULTS: The baseline characteristics of these 2 groups were equivalent and none patients received prior chemotherapy. The treatment response rate (P= .048) and progression free survival (PFS, P = .030) all demonstrated significant improvement compared with decitabine alone. Decitabine with CEG regimen had attained a CR rate of 45.7%, a median OS of 36 (19-53) months and a median PFS of 34 (16.7-51.3) months in high-risk MDS patients, a CR rate of 40% in sAML. While decitabine alone only attained a median OS of 26 (24.5-27.5) months and a CR rate of 18.2% as well as a median progression free survival of 20 (17.6-22.4) months in MDS patients. Treatment response to CR or PR and TP53 mutation were 2 prognostic factor for OS and PFS in decitabine with CEG regimen. CONCLUSION: Decitabine with CEG regimen showed some promising advantage in elderly, high-risk MDS.

OBJECTIVE: To evaluate the efficacy of decitabine combined with low-dose CEG regimen (DCEG) and decitabine combined with low-dose CAG regimen (DCAG) in the treatment of elderly patients with MDS and MDS-transformed acute myeloid leukemia (AML). METHODS: A prospective study was conducted in 7 medical centers, 45 patients with MDS (≥ 60 years old) and MDS-transformed AML from October 2016 to January 2019 were enrolled, with the median age of 68.5 years old. The risk stratification of patients was poor or very poor, according to IPSS-R score. The treament results of decitabine combined with CEG and decitabine combined with CAG were compared. RESULTS: The comparison of the two regiem showed that the DCEG regimen had advantages on total effective rate (ORR, 86.4% vs 47.8%, respectively), overall survival time (OS) (10.0 months vs 6.0 months, respectively) and progression-free survival time (PFS) (9.0 months vs 3.0 months, respectively). About 50% of MDS patients treated by DCEG regimen achieved PR or CR, with a median OS of 31 months. Multivariate analysis showed that patients with PR or CR after induction therapy and DCEG regimen had longer survival time (31months). The incidence of bone marrow suppression, infection and treatment-related mortality rate were similar between the two groups. CONCLUSION: Decitabine combined with CEG regimen could improve the survival of patients with high-risk MDS and MDS-transformed AML. The conclusion of the reaserch needs to be validated by a larger prospective randomized clinical trial.

Hemorrhage is the typical manifestation of APL-related coagulopathy while thrombosis is infrequently reported. In a retrospective analysis with 33 patients with hyperleukocytic APL, we found 6 out of 33 hyperleukocytic APL patients presented with thrombosis rather than hemorrhage. A notable feature in these high-risk APL patients with thrombosis is that there were no significant abnormalities in fibrinogen (FIB), prothrombin time (PT) and activated partial thromboplastin time (APTT). Compared with the normal ranges, both the high-risk APL patients with thrombosis and the high-risk APL patients with hemorrhage had a significant increase in fibrinogen degradation product (FDP) and d-dimer levels. However, the group with hemorrhage had noticeably higher plasma levels of FDP and d-dimer than the group with thrombosis. To find a close relationship between coagulation markers and the onset of thrombotic events in patients with high-risk APL, the potential effects of FDP/FIB and d-dimer/FIB ratios as risk markers were investigated. We demonstrated that FDP/FIB and d-dimer/FIB ratios in the patients with high-risk APL with thrombosis showed higher ratios than the normal range but significantly lower ratios than the patients with high-risk APL-related hemorrhage. Our data demonstrated that the alteration in FDP/FIB and d-dimer/FIB ratios have more significant relevance than the levels of FIB, FDP or d-dimer as potential factors for predicting thrombosis and may help with designing more appropriately risk-adapted treatment protocols or personalized therapy.

OBJECTIVE: To investigate the clinical characteristics and clinical prognostic factors of patients with acute lymphoblastic leukemia (ALL). METHODS: Ninety-six ALL patients in our hospital from June 2012 to August 2014 were selected and their clinical data were collected. The related clinical data of patients were recorded, and the relation between clinical characteristics and therapeutic efficacy was analyzed. The COX analysis was used to reveal the risk factors affecting the patient's OS and DFS time. RESULTS: Among 96 ALL patients, 65 patients achieved complete remission (CR) after treatment. The age, immunophenotype, central nervous system leukemia (CNSL) and peripheral blood WBC count correlated with complete remission (P<0.05). The age, WBC count, platelet level, immune typing and consolidation therapy were the prognostic factors (P<0.05), the 2 year OS rate was influenced by age, WBC count, CD34 and consolidation therapy (P<0.05), the 2 year DFS rate was influenced by age, CD34 and consolidation therapy (P<0.05). CONCLUSION: Age, WBC counts, CD34 and consolidated treatment after remission are prognostic factors for ALL patients, which has guiding significance for clinical treatment of ALL.

We have demonstrated that 12-0-tetradecanoylphorbol-13-acetate (TPA) combined with vitamin D(3) (VD(3)) and cytosine arabinoside (Ara C) is effective and feasible for chronic myelogenous leukemia (CML) in blastic phase (BP). In the current study, the efficacy of TPA combined with inhibitor imatinib mesylate (imatinib) was investigated in patients with CML in BP that was resistant to standard-dose imatinib (400mg/day). The results suggested that TPA combined with imatinib (400mg/day) might overcome disease-poor response to conventional doses. So this approach deserves further evaluation as frontline therapy for newly diagnosed CML.

OBJECTIVE: To explore the correlation of Th17 cell rate and IL-17 level with pathogenetis of multiple myeloma(MM). METHODS: Forty-five cases of MM were enrolled in MM group, while 45 healthy volunteers were selected in control group. The rate of Th17 cells, levels of IL-17 and ß2-microglobulin(ß2-MG) in patients subgrouping according to ISS staging and treatment were detected by using flow cytometer and IL-17 assay kit. The correlation of Th17 cell rate and IL-17 level with MM was analyzed. RESULTS: The rate of Th17 cells and level of IL-17 in MM group were higher than those in control group(P<0.05), the rate of Th17 cells and level of IL-17 in ISS III stage patients were higher than those in ISS I and II stage patients(P<0.05); the rate of Th17 cells and level of IL-17 in ISS I and ISS II stage patients were not significant difference (P>0.05); the rate of Th17 cells and level of IL-17 in firstly treated, retreated/refractory patients were significantly higher than those in patients with effective treatment(P<0.05), while the rate of Th17 cells and level of IL-17 between firstly treated patients and retreated/refractory patients were not significant difference (P>0.05). The Th17 rate and IL-17 level in MM patients positively correlated with ß2-MG level (r=0.422, r=0.416, P<0.05). CONCLUSION: The obvious increase of Th17 rate, IL-17 and ß2-MG levels closely relates with pathogenesis of MM. The Th17 rate and IL-17 level may be used as important evidence for evaluation of ISS stage and therapeutic efficacy of MM.

OBJECTIVE: To explore the clinical value of arsenious acid (H3AsO3) for treating patients with acute promyelocytic leukemia (APL). METHODS: A total of 86 patients with APL were randomly divided into experimental group (43 cases) and control group (43 cases). The control group was treated by all trans retinoic acid combined with chemotherapy, the experimental group were treated by arsenous acid on the basis of the control group. RESULTS: The overall response rate (ORR) in experimental group (100.00%) was significantly higher than that in control group (88.37%) (P < 0.05). The time of returm to complete remission in experimental group (30.86 ± 4.34) was better than that in control group (42.42 ± 7.10) d (P < 0.05). The time of return to normal levels of peripheral WBC count (20.86 ± 9.28) × 109/L, hemoglobin count (68.62 ± 14.97) g/L and thrombocyte count in experimental group obviously less than that in control group (P < 0.05). The rates of high white blood syndrome (HWBS), disseminated intravascular coagulation (DIC) in experimental group were lower than that in control group (P < 0.05). The survival rates of 2 and 3 years in experimental group were higher than that in control group (P < 0.05). The recurrence rate after treatment in experimental group was lower than that in control group (P < 0.05). The application of arsenious acid was main factor for patients survival (P < 0.05). CONCLUSION: Arsenious acid can improve the clinical efficacy for the patients with acute promyelocytic leukemia, and reduce the complication, therefore it is worthy of application in clinic.
