This study builds a green equilibrium utility model to analyze how green finance affects the transition to a low-carbon economy, with a focus on examining the utility mechanism of green credit financial instruments on regional carbon emissions. Also included are appropriate data and variable indicators for green funding and carbon emission reduction initiatives. Additionally, the empirical study was carried out using the unit root test, co-integration test, optimal lag order and model stability test, and impulse response analysis. The findings indicate that the regional carbon emissions will decrease by around 0.6 units for every unit rise in the level of green financing development. Financial instruments that support green credits have a major beneficial impact on local carbon emissions, helping to accelerate the transition to a low-carbon economy and lower local carbon emissions.

Problem Spontaneous abortion ( SA) occurs before 20 gestational weeks. Approximately, half of recurrent SA has no identifiable cause. No report has yet been investigated the possible involvement of lnc RNA in pregnancy loss. Method of Study Sixteen pairs of pregnancies with spontaneous abortions ( SA) and induced abortions ( IA) were studied. Embryonic sacs and decidua were collected for each pregnancy. A Human Lnc RNA Array was employed to profile genomewide lnc RNAs, which were then validated by RT- PCR. Results Differentially expressed lnc RNAs were identified. Biological pathways were categorized into six major groups: infection and inflammation, metabolism, signaling and transcriptional regulation, smooth muscle contraction, cell process, and coagulation. Conclusions Infection and inflammation pathways regulated by lnc RNAs were determined as the predominant pathogenetic factors underlying the SA. Finding that antisense lnc RNAs have been either up- or down-regulated suggests that they may have both cis- and trans-regulations. [ABSTRACT FROM AUTHOR]

In this paper, the SiCN(Ni)/BN ceramic with excellent electromagnetic wave (EMW) absorption performance was successfully prepared. The Ni and Ni 3 Si were in situ formed by the introduction of nickel acetylacetonate (NA), which effectively improved the impedance matching performance of SiCN(Ni)/BN ceramics. The EMW absorption properties of the SiCN(Ni)/BN ceramics showed a trend of first increasing and then decreasing with the increase in content of NA. When the NA content reached 7 wt%, the impedance matching range of SiCN-7 was optimal. The minimum reflection loss (RL min ) of SiCN-7 reached -53.47 dB at 4.2 mm and the effective absorption bandwidth (EAB) was 2.32 GHz at 3.48 mm. Through the analysis of electrical conductivity, it was found that the proportion of polarization loss in dielectric loss was more than 99%. It is worth noting that the radar cross section (RCS) value of SiCN-7 absorber was lower than that of the perfect electrical conductor (PEC) plate in the range of -90-90°, and showed a larger coverage angle, indicating that it possessed a good practical application prospect in the field of electromagnetic wave absorption., Competing Interests: There are no conflicts to declare., (This journal is © The Royal Society of Chemistry.)

Fondaparinux inhibits thrombin generation by inactivating factor Xa, which has the potential to treat recurrent miscarriage (RM). However, more clinical evidence is required to support its application in Chinese women with RM. This research aimed to compare the live birth rate, gestational weeks at delivery, birth weight, Apgar score of newborns, and adverse reaction rates between fondaparinux and low molecular weight heparin (LMWH) in Chinese women with RM. Totally, 132 women with RM treated with fondaparinux or LMWH were included in this retrospective study. According to the corresponding treatment, women with RM were divided into the fondaparinux cohort (N = 45) and LMWH cohort (N = 87). The live birth rate was 68.9% in the fondaparinux cohort and 56.3% in the LMWH cohort, which was not different between the two cohorts (P = 0.161). Multivariable logistics regression analysis suggested that only previous miscarriage times (≥ 4 times vs. < 4 times) were independently related to a lower possibility of live birth in women with RM (odds ratio = 0.431, P = 0.036). It was also observed that gestational weeks at delivery (38.1 ± 1.4 vs. 37.7 ± 1.7 weeks) (P = 0.258), birth weight (2,923.7 ± 355.0 vs. 2,807.8 ± 334.0 g) (P = 0.144), and Apgar score of newborns (9.8 ± 0.5 vs. 9.6 ± 0.8) (P = 0.175) were not different between the fondaparinux cohort and LMWH cohort. Inspiringly, the total adverse reaction rate was reduced in the fondaparinux cohort vs. the LMWH cohort (20.0% vs. 37.9%) (P = 0.036). Fondaparinux results in similar pregnancy outcomes with lower adverse reaction rates compared to LMWH in Chinese women with RM.

Objectives: Bevacizumab is a commonly used anticancer drug in clinical practice, but it often leads to adverse reactions such as vascular endothelial damage, hypertension, arterial and venous thrombosis, and bleeding. This study investigated the protective effects of metformin against bevacizumab-induced vascular injury in a mouse model and examined the possible involvement of GDF15/PI3K/AKT/FOXO/PPARγ signaling in the effects., Materials and Methods: C57 male mice were purchased. To investigate metformin, the mice were assigned to the saline, bevacizumab (15 mg every 3 days), metformin (1200 mg/day), and bevacizumab+metformin groups. To investigate GDF15, the mice were assigned to the siNC+bevacizumab, siNC+bevacizumab+metformin, siGDF15+bevacizumab, and siGDF15+bevacizumab+metformin groups. Histological staining was used to evaluate vascular injury. Flow cytometry was used to evaluate apoptosis. ELISA was used to measure plasma endothelial injury markers and proinflammatory cytokines. qRT-PCR and western blot were used to determine the expression of GDF15 and PI3K/AKT/FOXO/PPARγ in aortic tissues., Results: Metformin alleviated bevacizumab-induced abdominal aortic injury, endothelial cell apoptosis, and systemic inflammation in mice (all P< 0.05). Metformin up-regulated GDF15 expression and PI3K/AKT/FOXO/PPARγ signaling in the abdominal aorta of mice treated with bevacizumab (all P< 0.05). siGDF15 abolished the vascular protective and anti-inflammatory effects of metformin (all P< 0.05). siGDF15 suppressed PI3K/AKT/FOXO/PPARγ signaling in the abdominal aorta of mice treated with bevacizumab (all P< 0.05)., Conclusion: Metformin attenuates bevacizumab-induced vascular endothelial injury, apoptosis, and systemic inflammation by activating GDF15/PI3K/AKT/FOXO/PPARγ signaling., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Objective: To study the regulatory effect of IL-35 on the balance of Treg/Th17 cells in AR patients., Method: In this study, 30 cases were randomly selected from outpatients of otolaryngological department in the second hospital of Hebei Medical university who were diagnosed as AR. Another 20 healthy cases enrolled from physical examination branch of our hospital were control group. The expression level of IL-35 and IL-17 in peripheral blood were detected by using ELISA and defeced CD4+CD25+Foxp3+ T cell and CD4+IL-17+T cell expression level were identified via flow cytometry., Result: The expression level of IL-35 in AR group was obviously lower than that in control group, and the difference was a statistically significance (t = -8.145, P < 0.01). The expression level of IL-17 in AR group was obviously higher than that in control group, and the difference was a statistically significance (t = 14.969, P < 0.01). There was a remarkable negative correlation between the IL-35 and IL-17 expression in the serum of AR group (r = -0.773, P < 0.01). The percentage of CD4+CD25+Foxp3+ T cell in CD4+ T cell was significant lower in AR group than that in control group (t = -13.678, P < 0.01). The percentage of CD4+IL-17+ T cell in CD4+ T cell was much higher in AR group than that in control group (t = 5.632, P < 0.01). There was a remarkable negative correlation between the Treg and Th17 expression in the peripheral blood of AR group (r = -0.613, P < 0.01). There was a positive correlation between the expression of CD4+ CD25+Foxp3+ T cell and IL-35. There was a negative correlation between the IL-35 and Th17 in AR group (r = 0. -594, P < 0.01)., Conclusion: The lower expression of IL-35 was related to the incidence of AR, and it was an important cytokines for that. The lower expression of IL-35 may inhibit the proliferation of Treg cells, lead to hyper function of Th17 cells, increase secretion of s IL-17 and result in unbalance of Treg/Th17 cells; these may be the important mechanism of the occurrence of AR, thus regulation of IL-35 may become a new target for the immunological therapy of AR.
