Objective To investigate the impact of Sca-1 bone marrow derived stem cells on apoptosis in murine cardiac fibroblasts and the molecular mechanisms of young(Y)Sca-1 bone marrow stem cell(BMSC)on old(O)cardiac fibroblast cell(CFC)apoptosis.Methods The apoptosis and survival of Y and O CFC were assessed under hypoxic conditions.Co-cultures of Y and O Sca-1 bone marrow-derived mesenchymal stem cells(BMSC)with O CFC were established to investigate the impact of Sca-1 BMSC on the apoptotic response and viability of O CFC,employing TUNEL staining,qRT-PCR,Western Blot,and CCK8 assays.Furthermore,differential secretion profiles of growth factors by Y and O Sca-1 BMSC were compared using qRT-PCR and ELISA analysis.Results Compared to Y CFC,O CFC exhibited an increased rate of apoptosis and a decreased rate of cell survival.However,when compared to O cells,Y Sca-1 BMC significantly reduced apoptosis in O CFC and enhanced cell survival.Moreover,Y Sca-1 BMSC demonstrated a higher secretion of GDF5(Growth Differentiation Factor 5)than O cells(P<0.05).Importantly,the protective effects of Y Sca-1 BMSC on apoptosis and survival in O CFC were abolished upon neutral-ization of GDF5 expression.Conclusion Y Sca-1 BMSC decreases O CFC apoptosis through GDF5.

This study investigated the prevalence of Borrelia burgdorferi,Anaplasma phagocy tophilum,Rickettsia typhi,Orientia tsutsugamushi,Leptospira interrogans,Francisella tularensis,and Babesia spp.in small mammals in the Qinghai plateau region,to provide a scientific basis for the prevention and control of local zoonotic diseases.Small mammals were cap-tured with snap traps at six sampling sites in the Qinghai plateau region.Liver,spleen,and kidney tissues were collected for detection of six bacterial pathogens with real-time PCR.Conventional PCR(cPCR)was used for Babesia detection,and the positive PCR products were sequenced and analyzed.The differences in pathogen detection rates among species and habitats were analyzed with x2 test or Fisher's exact test.In to-tal,235 small mammals from 15 species were captured.B.burgdorferi,L.interrogans,and Babesia were detected in 11 spe-cies of small mammals,whereas A.phagocytophilum,R.typhi,O.tsutsugamushi,and F.tularensis were not detected.B.burgdorferi was detected in 41 small mammals from nine species(Cricetulus longicaudatus,Apodemus peninsulae,Ochotona curzoniae,Mus m usc ulus,Meriones meridians,Microtus arvalis,Cricetidae,Ochotona cansus,and Allactaga sibirica),with an infection rate of 17.45％(41/235).L.interrogans was detected in eight small mammals from four species(C.longicaudatus,M.musculus,M.arvalis,and Microtus oeconomus),with an infection rate of 3.40％(8/235).Babesia was detected in only one Mustela altaica,with an infection rate of 0.85％(1/235).Statistically significant differences were ob-served in the detection rates of pathogens among small mammal species(x2=200.54,P＜0.05).Among habitats,the detection rate of B.burgdorferi was highest in the forest(Fisher's exact test,P＜0.05).B.burgdorferi and L.interrogans co-infection was observed in three M.arvalis and two C.longicaudatus.In addition,one Babesia sequence was obtained,which clustered with Babesia vulpes in the phylogenetic tree.B.burgdorferi,L.interrogans,and Babesia were the main pathogens prevalent in small mammals in the Qinghai plateau region and have potential to cause human diseases.Local authori-ties should strengthen the surveillance of corresponding zoonotic diseases,and formulate corresponding prevention and control measures.

Aim To observe whether the mechanosensitive ion channel Piezo1 was involved in the senescence of atrial fibroblasts by activating β-catenin based on our previous study which found marked increase of Piezo1 mRNA in senescent atrial fibroblasts. Methods Primary mouse atrial fibroblasts (MAFs) were isolated from male C57BL/6 mice (3-4 weeks) by enzyme digestion, and tert-butyl hydroperoxide (TBHP) was used to induce the senescence of cells. The ratio of senescent cells was detected by senescence-associated β-galactosidase (SA-β-Gal) staining. The protein levels of Piezo1, β-catenin/p-β-catenin, senescence-associated proteins p53 and p21 in the cells treated with TBHP (100 μmol · L

The current study explored the hepatotoxicity among closed-ring genipin, open-ring tautomer of genipin and gardenia blue that generated from genipin and amino acid reaction using HepaRG cells to identify the material basis of genipin-induced hepatotoxicity in vitro. The effects of temperature, pH value and different kinds of amino acids on the chemical structure tautomerism between closed-ring and open-ring tautomer of genipin and the production of gardenia blue were investigated firstly, which aimed to explicit the conditions that could distinguish the closed-ring genipin and its open-ring tautomer, and the conditions generating gardenia blue, which were applied to prepare different kinds of gardenia blue; the CCK-8 kit was employed to analyze the hepatotoxicity of closed-ring genipin, open-ring tautomer of genipin and gardenia blue. From the results, it was found that, the structure transformation from close-ring to open-ring of genipin could be inhibited under the condition with acid environment; being essential groups to generate gardenia blue, the primary amino group and the open-ring tautomer of genipin reacting to generate the dihydropyridine ring was probably the key structure of gardenia blue; the structure characteristics existed apparent distinction at the reactive temperature of 37 ℃ and 80 ℃; compared to the culture condition with pH = 7.4, the concentration of genipin with close-ring in culture medium was significantly increased at pH = 5, but the cell viability did not decreased; the cell toxicity of gardenia blue was apparently lower than open-ring tautomer of genipin, and even some kinds of gardenia blue showed growth promoting effect on HepaRG cells. Here, it was suggested potentially that open-ring tautomer of genipin be the important material basis to induce hepatotoxicity, which could provide a cue and lay a foundation for the elucidation of the underlying mechanism of genipin-induced hepatotoxicity.

Objective: To forecast mortality, age-standardized mortality, and probability of premature mortality from diabetes, and to simulate the impact of controlling risk factors by 2030 in China. Methods: We simulated the burden of disease from diabetes in six scenarios according to the development goals of risk factors control by the WHO and Chinese government. Based on the theory of comparative risk assessment and the estimates of the burden of disease for China from the Global Burden of Disease Study 2015, we used the proportional change model to project the number of deaths, age-standardized mortality, and probability of premature mortality from diabetes under different scenarios of risk factors control in 2030. Results: If the trends in exposures to risk factors from 1990 to 2015 continued. Mortality, age-standardized mortality, and probability of premature mortality from diabetes would increase to 32.57/100 000, 17.32/100 000, and 0.84% by 2030, respectively. During that time, mortality, age-standardized mortality and probability of premature mortality for males would all be higher than for females. If the goals of controlling risk factors were all achieved, the number of deaths from diabetes in 2030 would decrease by 62.10% compared to the predicted numbers based on the historical trends in exposure to risk factors, and the probability of premature mortality would drop to 0.29%. If only the exposure to a single risk factor were achieved by 2030, high fasting plasma glucose control would have the greatest impact on diabetes, resulting in a 56.00% reduction in deaths compared to the predicted numbers based on the historical trends, followed by high BMI (4.92%), smoking (0.65%), and low physical activity (0.53%). Conclusions: Risk factors control plays an important role in reducing the number of deaths, age-standardized mortality rate, and probability of premature mortality from diabetes. We suggest taking comprehensive measures to control relevant risk factors for certain populations and regions, to achieve the goal of reducing the burden of disease from diabetes as expected.

OBJECTIVES: To investigate the risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture and establish a nomogram model for predicting the risk of neonatal asphyxia. METHODS: A retrospective study was conducted with 613 cases of neonatal asphyxia treated in 20 cooperative hospitals in Enshi Tujia and Miao Autonomous Prefecture from January to December 2019 as the asphyxia group, and 988 randomly selected non-asphyxia neonates born and admitted to the neonatology department of these hospitals during the same period as the control group. Univariate and multivariate analyses were used to identify risk factors for neonatal asphyxia. R software (4.2.2) was used to establish a nomogram model. Receiver operator characteristic curve, calibration curve, and decision curve analysis were used to assess the discrimination, calibration, and clinical usefulness of the model for predicting the risk of neonatal asphyxia, respectively. RESULTS: Multivariate logistic regression analysis showed that minority (Tujia), male sex, premature birth, congenital malformations, abnormal fetal position, intrauterine distress, maternal occupation as a farmer, education level below high school, fewer than 9 prenatal check-ups, threatened abortion, abnormal umbilical cord, abnormal amniotic fluid, placenta previa, abruptio placentae, emergency caesarean section, and assisted delivery were independent risk factors for neonatal asphyxia (P<0.05). The area under the curve of the model for predicting the risk of neonatal asphyxia based on these risk factors was 0.748 (95%CI: 0.723-0.772). The calibration curve indicated high accuracy of the model for predicting the risk of neonatal asphyxia. The decision curve analysis showed that the model could provide a higher net benefit for neonates at risk of asphyxia. CONCLUSIONS The risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture are multifactorial, and the nomogram model based on these factors has good value in predicting the risk of neonatal asphyxia, which can help clinicians identify neonates at high risk of asphyxia early, and reduce the incidence of neonatal asphyxia.

This study explored the usefulness of two-dimensional shear wave elastography (2D-SWE) in the early assessment of corpora cavernosa fibrosis (CCF). New Zealand male rabbits were randomly assigned to an experimental group or a control group. Recombinant human transforming growth factor beta 1 (TGF-β1) was injected into the dorsal penis tissue of rabbits in the experimental group. Conventional ultrasound and 2D-SWE examinations were performed before and 20 days after injection. Penile histological analysis was performed by hematoxylin-eosin staining, sirius red staining, and immunohistochemistry. Measurement of 2D-SWE examination results was performed using shear wave elastography quantitative measurement (SWQ). Histological analysis outcomes were the proportion of smooth muscle cells (SMCs), collagen fibers (CFs), collagen type I (Col I), and collagen type III (Col III), as well as the SMCs/CFs ratio, measured by sirius red staining. Other histological analysis outcomes were the positive area proportion (PAP) of TGF-β1 (PAP_T), fibronectin (PAP_F), and Col III (PAP_C), measured by immunohistochemistry. After recombinant human TGF-β1 injection, SWQ was higher in the experimental group than that in the control group (P < 0.001); however, there were no differences in conventional ultrasound results. There were significant differences in histological outcomes between the two groups (all P < 0.05). These results indicated that 2D-SWE was superior for identifying early histological changes in CCF.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

Objective: Predictive models were used to evaluate the impact of common risk factors on the number of cardio-cerebrovascular deaths and the probability of premature death. Methods: Using the data for China estimated by the Global Burden of Disease study 2015 (GBD 2015), we calculated the population attribution fraction (PAF) of risk factors. The proportional change model was used to estimate the number of unattributable deaths by 2030, and to predict the number of deaths, mortality, standardized mortality and probability of premature death by 2030. Results: According to the natural change trend of risk factors from 1990 to 2015, the number of deaths and mortality would reach 6.12 million and 428.53/100 000 by 2030, with an increase of 59.92% and 52.87%. By 2030, the probability of premature death from cardio-cerebrovascular diseases among Chinese aged 30-70 years old would continue to decline, from 11.43% to 11.28% for men, and from 5.79% to 4.43% for women. If the goals of all included risk factors were reached by 2030, 2 289 200 cardio-cerebrovascular deaths would be avoided. If only the exposure to a single risk factor was achieved by 2030, blood pressure, total cholesterol, and fine particulate matter exposure were the three most important factors affecting cardio-cerebrovascular deaths, which would reduce 1 332 800, 609 100 and 306 800 deaths, respectively. Among the involved risk factors, the control of blood pressure would mostly decrease the number of deaths due to ischemic heart disease and hemorrhagic stroke, about 677 300 and 391 100 deaths, accordingly. Conclusion: The control of risk factors is of great significance in reducing deaths and probability of premature death due to cardio-cerebrovascular diseases. If the control targets of all risk factors could be achieved by 2030, the burden of cardio-cerebrovascular diseases would be reduced greatly.
