RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Baiheqingjin Decoction (BHQJ), which consists of 7 traditional Chinese herbs including Baibu (Stemona tuberosa Lour.), Hezi (Terminalia chebula Retz.), Mahuang (Ephedra sinica Stapf.), Ziwan (Aster tataricus L. f.), Dilong (Pheretima), Sangbaipi (Morus alba L.), and Xianhecao (Agrimonia pilosa Ledeb.). BHQJ is commonly used for treating cough asthma, and variant cough-variant asthma as it, is effective in improving asthma symptoms and reducing airway inflammation. AIM OF THE STUDY: To investigate the mechanisms of BHQJ in treating allergic asthma. MATERIALS AND METHODS: We collected information about the components and targets of 6 Chinese medicines (excluding Pheretima) from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP). Additionally, we obtained genes associated with asthma from six disease databases. To create a protein-protein interaction network, we conducted an intersection analysis using differentially expressed genes derived from RNA transcriptome data. Subsequently, we carried out Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses. To validate the findings from network pharmacology and transcriptomics, we established an allergic asthma mouse model induced by ovalbumin and conducted in vivo experiments. RESULTS: Using network pharmacology and transcriptomics analyses, we identified the pathways including the PI3K/AKT signaling pathway, and NF-κB signaling pathway. Among these, the involvement of the PI3K/AKT/NF-κB signaling pathway in various pathological processes of asthma, such as airway inflammation, smooth muscle contraction, and excessive mucus production, are well-documented. Histopathological examinations indicated that BHQJ had the potential to mitigate inflammatory cell infiltration and the excessive growth of goblet cells in the airways of asthmatic mice, consequently reducing mucus secretion. Results from Western blot demonstrated that BHQJ could inhibit the activation of the PI3K/AKT/NF-κB pathway at the protein levels. Enzyme-linked immunosorbent assay findings revealed that BHQJ could reduce the production of typical "type 2 asthma" cytokines and immunoglobulin (Ig) E in the blood. These discoveries imply that BHQJ has the potential to reduce the release of inflammatory cytokines and suppress the overactivation of the PI3K/AKT/NF-κB signaling pathway, thus offering a therapeutic approach for asthma. CONCLUSION: Our research offers initial insights into the fundamental mechanisms through which BHQJ treats asthma. This study reveals the potential mechanism of BHQJ in treating asthma, particularly its role in reducing inflammatory cytokines, mucus production, and cell infiltration, as well as inhibiting the expression of PI3K/AKT/P65 phosphorylated protein. These findings indicate the potential of BHQJ in treating asthma. In summary, our study provides preliminary insights into the asthma treatment mechanism of BHQJ and provides guidance for future research.

RESUMO

OBJECTIVE: To investigate the associations between low education and risk of mental disorders, substance use disorders and self-harm in different age-groups. METHODS: All subjects in Stockholm born between 1931 and 1990 were linked to their own or their parent's highest education in 2000 and followed-up for these disorders in health care registers 2001-2016. Subjects were stratified into four age-groups: 10-18, 19-27, 28-50, and 51-70 years. Hazard Ratios with 95% Confidence Intervals (CIs) were estimated with Cox proportional hazard models. RESULTS: Low education increased the risk of substance use disorders and self-harm in all age-groups. Males aged 10-18 with low education had increased risks of ADHD and conduct disorders, and females a decreased risk of anorexia, bulimia and autism. Those aged 19-27 years had increased risks of anxiety and depression, and those aged 28-50 had increased risks of all mental disorders except anorexia and bulimia in males with Hazard Ratios ranging from 1.2 (95% CIs 1.0-1.3) for bipolar disorder to 5.4 (95% CIs 5.1-5.7) for drug use disorder. Females aged 51-70 years had increased risks of schizophrenia and autism. CONCLUSION: Low education is associated with risk of most mental disorders, substance use disorders and self-harm in all age-groups, but especially among those aged 28-50 years.

RESUMO

There is a paucity of research examining the patterning of socioeconomic disadvantages and mental health problems across multiple generations. The current study therefore aimed to investigate the interconnected transmissions of socioeconomic disadvantages and mental health problems from grandparents to grandchildren through the parents, as well as the extent to which these transmissions differ according to lineage (i.e., through matrilineal/patrilineal descent) and grandchild gender. Drawing on the Stockholm Birth Cohort Multigenerational Study, the sample included 21,416 unique lineages by grandchild gender centered around cohort members born in 1953 (parental generation) as well as their children (grandchild generation) and their parents (grandparental generation). Based on local and national register data, socioeconomic disadvantages were operationalized as low income, and mental health problems as psychiatric disorders. A series of path models based on structural equation modelling were applied to estimate the associations between low income and psychiatric disorders across generations and for each lineage-gender combination. We found a multigenerational transmission of low income through the patriline to grandchildren. Psychiatric disorders were transmitted through both the patriline and matriline, but only to grandsons. The patriline-grandson transmission of psychiatric disorder partially operated via low income of the fathers. Furthermore, grandparents' psychiatric disorders influenced their children's and grandchildren's income. We conclude that there is evidence of transmissions of socioeconomic disadvantages and mental health problems across three generations, although these transmissions differ by lineage and grandchild gender. Our findings further highlight that grandparents' mental health problems could cast a long shadow on their children's and grandchildren's socioeconomic outcomes, and that socioeconomic disadvantages in the intermediate generation may play an important role for the multigenerational transmission of mental health problems.

RESUMO

Baicalin (BA) is a major flavone from Scutellaria baicalensis Georgi and has showed significant curative effects in Parkinson's and Alzheimer's diseases. In the present study, we investigated the effects of BA on antineuroinflammation and related signaling cascade in lipopolysaccharide- (LPS-) induced BV-2 microglial model. The results showed that BA significantly attenuated inflammatory mediators (NO, iNOS, IL-1ß, COX-2, and PGE2) and suppressed the expression of miR-155. More crucially, BA could regulate the expression of related proteins in Toll-like receptor 4 (TLR4)/myeloid differentiation protein 88 (MyD88)/nuclear factor κB (NF-κB) pathway and suppress the phosphorylation of mitogen-activated protein kinase (MAPK) family. In addition, molecular docking analysis indicated that BA binds to the amino acids Lie 63 and Tyr 65 of TLR4 by π-σ and π-π T-shaped interaction. Thus, BA suppressed the LPS-stimulated neuroinflammation in BV-2 microglia by blocking the TLR4-mediated signal transduction through TLR4/MyD88/NF-κB and MAPK pathways and inhibiting the miR-155 expression. Our findings demonstrated that BA could be a valuable therapeutic for the treatment of neuroinflammation and neurodegenerative diseases.

RESUMO

Toad venom (Chansu) is used in the treatment of infectious and inflammatory diseases in China and East/Southeast Asian countries. However, the anti-inflammatory components of toad venom have not yet been systematically evaluated and clearly defined. To investigate the anti-inflammatory effects of toad venom and identify new anti-inflammatory ingredients, we used zebrafish, an alternative drug screening model, to evaluate the anti-inflammatory effects of 14 bufadienolides previously isolated from toad venom. Most of the bufadienolides were found to exert significant anti-inflammatory effects on lipopolysaccharide-, CuSO4-, or tail transection-induced zebrafish inflammatory models. Moreover, gammabufotalin ( 6: ) inhibits lipopolysaccharide-induced inflammation by suppressing the myeloid differentiation primary response 88/nuclear factor-kappa B and STAT3 signal pathways. This study confirms the potential of zebrafish in drug screening, clarifies the anti-inflammatory effects of bufadienolides from toad venom, and indicates that gammabufotalin may be developed as a novel therapeutic agent for inflammatory diseases in the future.

RESUMO

OBJECTIVES: This study aimed to find out the protective effects and preliminary mechanisms of the flower extract of Caragana sinica (FEC) on dextran sulfate sodium salt (DSS)-induced colitis. MATERIALS AND METHODS: The ulcerative colitis models of mice induced by 3% DSS were established and treated with FEC. Body weight changes, disease activity index (DAI), colon histopathological score, anti-oxidant ability, and the level of inflammatory cytokines were determined. The expression of Toll-like receptor 4 (TLR4) and myeloid differentiation factor 88 (MyD88) were assessed in colonic tissue by immunohistochemical staining. Western blot was used to analyze the expression of TLR4/ nuclear factor kappa-B (NF-κB) and TLR4/ mitogen-activated protein kinase (MAPK) signaling pathway-related proteins. RESULTS: FEC significantly prevented body weight loss and colonic shortening and reduced the disease activity index and histopathological score (P<0.05). Moreover, FEC treatment remarkably down-regulated the levels of myeloperoxidase (MPO), interleukin-1beta (IL-1ß), tumor necrosis factor-alpha (TNF-α), and interleukin 6 (IL-6) and up-regulated the levels of superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), and interleukin 10 (IL-10) in the colon of DSS mice (P<0.05). Furthermore, the expression of TLR4/NF-κB and TLR4/MAPK pathway-related proteins was inhibited by FEC (P<0.05). CONCLUSION: Our findings demonstrated that FEC could serve as a potential therapeutic agent for treatment of ulcerative colitis.

RESUMO

Limited epidemiological literature identified the associations between residential greenness and hypertension in low-/middle-income countries. A random sampling strategy was adopted to recruit 39,259 residents, ≥ 18 years, and from 5 counties in central China. Blood pressure was measured based on the protocol of the American Heart Association. Hypertension was defined according to the 2010 Chinese guidelines for the management of hypertension. The satellite-derived normalized difference vegetation index (NDVI) and enhanced vegetation index (EVI) were applied to estimate the residential greenness. Mixed logit model and mixed linear model were utilized to explore the relationships of residential greenness with hypertension and blood pressure. Higher residential greenness was associated with lower odds of hypertension and blood pressure levels. For instance, an interquartile range (IQR) increase in NDVI500m was linked with lower odds of hypertension (OR = 0.92, 95%CI 0.88 to 0.95), a decrease of -0.88 mm Hg (95% CI -1.17 to -0.58) and -0.64 mm Hg (95% CI -0.82 to -0.46) in SBP and DBP, respectively. The effect of residential greenness was more pronounced in males, smokers, and drinkers. Long-term exposure to residential greenness was linked with lower odds of hypertension. More prospective studies are needed to verify the hypothesis.

RESUMO

Two new sesquiterpenoids, including a kessane-type sesquiterpenoid (1) and one bisabolane derivative (2), together with fourteen known sesquiterpenoids (3-16), were isolated from the roots and rhizomes of Valeriana amurensis. The structures of new compounds were established on the basis of extensive spectroscopic analysis. All isolates were evaluated for their effects on nerve growth factor (NGF)-mediated neurite outgrowth in pheochromocytoma (PC12) cells. As a results, four compounds including 10-12 and 15 showed potent promoting effects at the concentration of 10 µM on NGF-induced neurite outgrowth in PC12 cells with the differentiation rate of 11.84%, 12.21%, 13.77% and 12.16%, respectively.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Chansu, dried secretions from Bufonidae, has long been used for cancer treatment as a traditional Chinese medicine. In searching for effective anti-hepatoma agents from Chansu, our preliminary drug screening found that a bufadienolide, namely 1ß-hydroxyl-arenobufagin (1ß-OH-ABF), displays anti-hepatoma activities. However, the anti-hepatoma effects and molecular mechanisms of 1ß-OH-ABF have not been defined. AIM OF THE STUDY: To evaluate the anti-hepatoma activity of 1ß-OH-ABF against liver cancer Hep3B and HepG2 cells in vitro and in vivo, as well as explore the underlying mechanisms. MATERIALS AND METHODS: The anti-proliferative effects of 1ß-OH-ABF on liver cancer Hep3B, HepG2, HuH7, SK-HEP-1 and normal hepatocyte LO2 cells were examined by MTT assay and colony formation assay. Hoechst 33258 staining and Annexin V-FITC/PI staining assay were used to analyze apoptosis induced by 1ß-OH-ABF. The collapse of the mitochondrial membrane potential (ΔΨm) was detected by JC-1 staining assay. Western blotting was used to examine the expression levels of targeted proteins. The role of mTOR in 1ß-OH-ABF-induced apoptosis was investigated using small interfering RNA (siRNA) transfection. Zebrafish xenograft model was established to evaluate the anti-hepatoma effects of 1ß-OH-ABF in vivo. RESULTS: We found that 1ß-OH-ABF inhibits the proliferation of Hep3B, HepG2, HuH7, SK-HEP-1 cells but has little cytotoxicity towards LO2 cells. 1ß-OH-ABF induces mitochondria dysfunction and triggers mitochondria apoptotic pathway, which is accompanied by the loss of ΔΨm, upregulation and translocation of Bax, as well as cleavages of caspase-9, caspase-3 and PARP. Mechanistically, 1ß-OH-ABF markedly decreases the expression level of p-AKT/AKT and p-mTOR (Ser2248 and Ser2481)/mTOR in a time-dependent manner. Inhibition of mTOR by siRNA strengthens 1ß-OH-ABF-mediated apoptosis. Critically, 1ß-OH-ABF shows a marked in vivo anti-hepatoma effect on human Hep3B cell xenografts in zebrafish model. CONCLUSION: 1ß-OH-ABF induces mitochondrial apoptosis through the suppression of mTOR signaling in vitro and in vivo, indicating that 1ß-OH-ABF may serve as a potential agent for the treatment of liver cancer.

RESUMO

Leukemia is one of the most common cancers. We conducted this study to comprehensively analyze the temporal trends of leukemia mortality during 2003-2017 and project the trends until 2030. We extracted national-level data on annual leukemia mortality from China Health Statistics Yearbooks (2003-2017). We applied the Joinpoint regression model to assess leukemia mortality trends in urban and rural China by sex during 2003-2017. We also produced sex-specific leukemia mortality using the adjusted Global Burden Disease (GBD) 2016 projection model. In urban areas, age-standardized leukemia mortality decreased significantly among females during 2003-2017 (APC = -0.9%; 95% CI: -1.7, -0.1%). In rural areas, significant decreases of age-standardized leukemia mortality were both found among males (APC = -1.7%; 95% CI: -2.9, -0.5%) and females (APC = -1.6%; 95% CI: -2.6, -0.7%) from 2008 to 2017. Rural-urban and sex disparities of leukemia mortality will continue to exist until the year 2030. According to projection, the leukemia mortality rates of males and rural populations are higher than that of females and urban populations. In 2030, leukemia mortality is projected to decrease to 3.03/100,000 and 3.33/100,000 among the males in urban and rural areas, respectively. In females, leukemia mortality will decrease to 1.87/100,000 and 2.26/100,000 among urban and rural areas, respectively. Our study suggests that more precautionary measures to reduce leukemia mortality are need, and more attention should be paid to rural residents and males in primary prevention of leukemia in China.

RESUMO

BACKGROUND: Decreased heart rate variability (HRV) is a predictor of autonomic system dysfunction, and is considered as a potential mechanism of increased risk of cardiovascular disease (CVD) induced by exposure to particulate matter less than 2.5 µm in diameter (PM2.5). Previous studies have suggested that exposure to PM2.5 may lead to decreased HRV levels, but the results remain inconsistent. METHODS: An updated systematic review and meta-analysis of panel studies till November 1, 2019 was conducted to evaluate the acute effect of exposure to ambient PM2.5 on HRV. We searched electronic databases (PubMed, Web of Science, and Embase) to identify panel studies reporting the associations between exposure to PM2.5 and the four indicators of HRV (standard deviation of all normal-to-normal intervals (SDNN), root mean square of successive differences in adjacent normal-to-normal intervals (rMSSD), high frequency power (HF), and low frequency power (LF)). Random-effects model was used to calculate the pooled effect estimates. RESULTS: A total of 33 panel studies were included in our meta-analysis, with 16 studies conducted in North America, 12 studies in Asia, and 5 studies in Europe. The pooled results showed a 10 µg/m3 increase in PM2.5 exposure which was significantly associated with a - 0.92% change in SDNN (95% confidence intervals (95%CI) - 1.26%, - 0.59%), - 1.47% change in rMSSD (95%CI - 2.17%, - 0.77%), - 2.17% change in HF (95%CI - 3.24%, - 1.10%), and - 1.52% change in LF (95%CI - 2.50%, - 0.54%), respectively. Overall, subgroup analysis suggested that short-term exposure to PM2.5 was associated with lower HRV levels in Asians, healthy population, and those aged ≥ 40 years. CONCLUSION: Short-term exposure to PM2.5 was associated with decreased HRV levels. Future studies are warranted to clarity the exact mechanism of exposure to PM2.5 on the cardiovascular system through disturbance of autonomic nervous function.

RESUMO

To understand the current status of, and factors related to interpersonal sensitivity (IS) and loneliness among Chinese gay men. The Chinese version SCL-90-R was used to evaluate the status of IS, and the short-form UCLA Loneliness scale (ULS-8) was used for assessing loneliness level. Associations between demographics and IS were examined by chi-square tests and multivariable logistic regress analysis. Linear regression was used to assess the correlations between demographic factors and IS and loneliness. Dating practices and venues were summarized by multiple responses. Gay men who screened positive IS was identified in 36%. Age (OR25-29 = 8.731, 95% CI 2.296 to 33.139), education level (ORcollege = 0.037, 95% CI 0.046 to 0.911), being the only-child at home (ORyes = 4.733, 95% CI 2.293 to 9.733), monthly income (OR>7000 = 0.228, 95% CI 0.055 to 0.944), numbers of current sexual partners (OR1 = 0.285, 95% CI 0.129 to 0.629; OR2 = 0.109 95% CI 0.027 to 0.431) were related to IS. IS was also associated with a higher score of ULS-8 (ß = 6.903, p < 0.001). Other variables associated with the score of ULS-8 included: living in a non-nuclear family (ß = 0.998, p = 0.020), being a college student (ß = -1.556, p = 0.044), having a higher monthly income (ß for 3000-5000 yuan = -1.177, p = 0.045; ß for over 7000 yuan = -2.207, p = 0.002), having sexual partners (all ß < 1, p < 0.001), being the only-child (ß = 1.393, p = 0.005). Nearly half of the sample (46.78%) reported that they looked for dating partners on the Internet or dating apps. IS and loneliness are positively correlated. Our study suggests that more humanistic care and social support should be given to Chinese gay men.

RESUMO

INTRODUCTION: As lifestyles have increasingly become westernized in China, public health strategies have increasingly focused on cancer prevention. The objective of this study was to describe trends in colorectal cancer (CRC) mortality and the age, period, and cohort effects of CRC mortality in urban and rural China from 2000 to 2015. METHODS: We collected CRC mortality data from the China Health Statistics Yearbook. We used joinpoint regression analysis to estimate the slope of mortality trends. We then used the age-period-cohort (APC) model with intrinsic estimator to estimate the age, period, and cohort effects of CRC mortality. RESULTS: CRC mortality was higher in urban areas than in rural areas, and the average annual percentage change was also larger in urban areas (4.1%) than in rural areas (3.7%). CRC mortality risk was higher among older adults than among adults aged 20 to 24: the relative risk among adults aged 60 to 64 was 31.09 times higher in urban China and 11.46 times higher in rural China. CRC mortality risk increased with period: compared with period 2000, the relative risk was 1.01 in period 2005, 1.36 in period 2010, and 1.42 in period 2015 in urban China and 1.12 in period 2005, 1.24 in period 2010, and 1.69 in period 2015 in rural China. More recent cohorts had lower CRC mortality risk: compared with the cohort born during 1920-1924, the relative risk of cohort 1950-1954 was 0.70 in urban China and 0.69 in rural China. CONCLUSION: More interventions to reduce the burden of CRC should be conducted, and it is more necessary for older people and urban residents to adopt a healthy lifestyle in China.

RESUMO

PURPOSE: This study evaluated the current situation and possible influencing factors associated with prison medical workers' (PMWs') somatization, obsessive-compulsive symptoms, and their job satisfaction. PARTICIPANTS AND METHODS: The Chinese version of Symptom Checklist-90-R (SCL-90-R) was used to assess PMWs' mental health conditions. Logistic regression analysis was used to identify the main factors associated with PMWs' somatization, obsessive-compulsive symptoms, and their job satisfaction. The correlations between PMWs' somatization, obsessive-compulsive symptoms, and job satisfaction were examined. RESULTS: The positive detection rates of somatization and obsessive-compulsive symptoms among the PMWs were 22.73% and 47.27%, respectively. Age, educational level, and length of working in prison were factors related to the PMWs' mental health. Half of the PMWs were not satisfied with their current job, particularly the females and young workers with a shorter period of service. PMWs' somatization is strongly positively correlated with obsessive-compulsive symptoms, while job satisfaction is negatively correlated with having somatization symptoms and obsessive-compulsive disorders. CONCLUSION: PMWs with lower educational level, elderly workers, and new employees have higher risk and more serious somatization and obsessive-compulsive symptoms. The female and young PMWs with a short service time were particularly not satisfied with their job. Findings from this study indicated that it is important and necessary to improve PMWs' job satisfaction in order to reduce their somatization symptoms and obsessive-compulsive disorders.

RESUMO

OBJECTIVE: To study the role of non-classical NF-κB signaling pathway in B acute lymphoblastic leukemia (B-ALL). METHODS: The bone marrow samples from 48 patients with B-ALL were collected from March 2015 to March 2016. The real-time quantitative RT-PCR was used for determing mRNA expression levels of NF-κB family members; the NF-κB DNA binding activity in B-ALL cell nucleus was analyzed by ELISA; the apoptosis rate of B-ALL cells alone or co-cultured with bone marrow stromal cells (hBMSC) was determined by flow cytometry. RESULTS: Relative expression level of mRNA for NF-κB family members, including the Rel A, Rel B, P50 and P52 in ALL-B group was statistically significantly higher than that in normal control group (P<0.05). The clinical characteristics of B-ALL patients with different NF-κB activity were not significantly different (P> 0.05); after B-ALL cells cultured alone or co-cultured, the apoptosis rate of Rel A+ / Rel B- group was statistically significantly higher than that in Rel A+ / Rel B+ group (P<0.05); the apoptosis rate of B-ALL cells cultured alone or co-cultured with hBMSC was significantly different. CONCLUSION: Non-classical NF-κB signal marked by Rel B can be used as a new target for B-ALL treatment.
