Objective:
To investigate the associations between early life exposure to particulate matter with an aerodynamic diameter less than 2.5 μm (PM 2.5 ) and the risk of autism spectrum disorder (ASD) among school aged children.
Methods:
A total of 165 children with ASD and 165 age and gender matched typical development (TD) children were recruited. Children s basic information were obtained via questionnaires, and the severity of ASD symptoms was assessed with Social Responsiveness Scale (SRS). Early life PM 2.5 exposure (preconception, entire pregnancy, and the first two years after birth) were extracted from the Tracking Air Pollution in China (TAP) datasets. Conditional Logistic regression and generalized linear model were used to evaluate the associations of early life exposure to PM 2.5 with the risk and the ASD severity symptoms, respectively.
Results:
The PM 2.5 exposure of ASD group during preconception[(55.08±9.34)μg/m 3], entire pregnancy[(50.44±8.71)μg/m 3], the first year after birth [(45.04± 8.25 )μg/m 3] and the second year after birth [(40.19±7.12)μg/m 3] were significant higher than those in TD children [(47.66± 7.63 , 44.19±7.16, 38.95±6.07, 35.76±5.65)μg/m 3]( t =7.94, 7.13, 7.70, 6.32, P <0.05). After adjusting for potential confounding, each increase of 1 μg/m 3 in PM 2.5 was associated with higher risk of ASD during preconception ( OR=1.21, 95%CI =1.13-1.29), entire pregnancy( OR=1.18, 95%CI =1.11-1.26), the first year after birth ( OR=1.30, 95%CI =1.18-1.43) and the second year after birth ( OR=1.29, 95%CI =1.17-1.42). No similar results were observed regarding the analyses of SRS total and sub scale scores( P >0.05).
Conclusion
Early life exposure to PM 2.5 is relate to the risk of ASD, these findings indicated that more attention should be paid to ambient PM pollution in the early life prevention and control of ASD.

Objective:To investigate the inhibitory effect and mechanism of heme oxygenase-1 (HO-1) on the inflammatory response of macrophages.Methods:Mouse macrophage strain RAW264.7 was cultured in vitro, and the cells in the logarithmic growth phase were used for the experiment. The RAW264.7 cells were divided into four groups. In blank control group, the cells were continuously incubated and received no treatment (cultured at 37 ℃, 95% air, 5% CO 2). In lipopolysaccharide (LPS) model group, 1 mg/L LPS was added to the medium to prepare LPS challenge model. In HO-1 inducer group, the cells were incubated with 30 μmol/L HO-1 inducer hemin for 1 hour, and then 1 mg/L LPS was added for incubation. In HO-1 inhibition group, the cells were incubated with 5 μmol/L HO-1 specific antagonist Zinc protoporphyrin Ⅸ (ZnPPⅨ) for 0.5 hour, and then 1 mg/L LPS was added for incubation. After 48 hours of incubation with LPS, the supernatant of each group was taken, and the protein expressions of HO-1, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), thioredoxin interacting protein (TXNIP), NOD-like receptor protein 3 (NLRP3) and mitochondrial autophagy marker microtubule-associated protein 1 light chain 3B (LC-3B) were detected by Western blotting. The expression of reactive oxygen species (ROS) was detected by immunofluorescence staining. Results:Compared with the blank control group, the cells in the LPS model group had a certain stress response, and autophagy occurred in mitochondria, but the expression of some inflammatory factors was restricted, which was related to the impairment of cell function. The protein expressions of HO-1, IL-1β, LC-3B, ROS were significantly increased, the protein expressions of TNF-α, TXNIP, and NLRP3 were decreased significantly, indicating that the cells were seriously injured after LPS challenge, and the model was successfully established. Compared with the LPS model group, HO-1 protein expression in the HO-1 inducer group was significantly increased (HO-1/GAPDH: 0.31±0.03 vs. 0.22±0.03, P < 0.05), the protein expressions of TNF-α, IL-1β, TXNIP, NLRP3, LC-3B and ROS were significantly inhibited [TNF-α protein (TNF-α/GAPDH): 0.08±0.01 vs. 0.45±0.05, IL-1β protein (IL-1β/GAPDH): 0.50±0.01 vs. 0.82±0.03, TXNIP protein (TXNIP/GAPDH): 0.21±0.02 vs. 0.28±0.02, NLRP3 protein (NLRP3/GAPDH): 0.11±0.01 vs. 0.17±0.02, LC-3B protein (LC-3B/GAPDH): 0.67±0.04 vs. 0.92±0.12, ROS (fluorescence intensity): 80.9±12.5 vs. 94.1±19.5, all P < 0.05], indicating that HO-1 could inhibit inflammatory response and oxidative stress, and reduce mitochondrial autophagy. Antagonizing HO-1 could increase inflammatory response, oxidative stress and mitochondrial autophagy, the inhibitory degree of TNF-α and IL-1β expression was significantly reduced as compared with the HO-1 inducer group [TNF-α protein (TNF-α/GAPDH): 0.26±0.02 vs. 0.08±0.01, IL-1β protein (IL-1β/GAPDH): 0.76±0.01 vs. 0.50±0.01, both P < 0.05], the protein expressions of TXNIP, NLRP3, LC-3B and ROS were significantly increased as compared with the LPS model group [TXNIP protein (TXNIP/GAPDH): 0.43±0.02 vs. 0.28±0.02, NLRP3 protein (NLRP3/GAPDH): 0.24±0.02 vs. 0.17±0.02, LC-3B protein (LC-3B/GAPDH): 1.12±0.07 vs. 0.92±0.12, ROS (fluorescence intensity): 112.0±17.0 vs. 94.1±19.5, all P < 0.05]. Conclusion:HO-1 can reduce the inflammatory response by inhibiting the activation of TXNIP/NLRP3 inflammasome and reducing the release of inflammatory mediators.

BACKGROUND:
Data on the immunogenicity and safety of heterologous immunization schedules are inconsistent. This study aimed to evaluate the immunogenicity and safety of homologous and heterologous immunization schedules.
METHODS:
Multiple databases with relevant studies were searched with an end date of October 31, 2021, and a website including a series of Coronavirus disease 2019 studies was examined for studies before March 31, 2022. Randomized controlled trials (RCTs) that compared different heterologous and homologous regimens among adults that reported immunogenicity and safety outcomes were reviewed. Primary outcomes included neutralizing antibodies against the original strain and serious adverse events (SAEs). A network meta-analysis (NMA) was conducted using a random-effects model.
RESULTS:
In all, 11 RCTs were included in the systematic review, and nine were ultimately included in the NMA. Among participants who received two doses of CoronaVac, another dose of mRNA or a non-replicating viral vector vaccine resulted in a significantly higher level of neutralizing antibody than a third CoronaVac 600 sino unit (SU); a dose of BNT162b2 induced the highest geometric mean ratio (GMR) of 15.24, 95% confidence interval [CI]: 9.53-24.39. Following one dose of BNT162b2 vaccination, a dose of mRNA-1273 generated a significantly higher level of neutralizing antibody than BNT162b2 alone (GMR = 1.32; 95% CI: 1.06-1.64), NVX-CoV2373 (GMR = 1.60; 95% CI: 1.16-2.21), or ChAdOx1 (GMR = 1.80; 95% CI: 1.25-2.59). Following one dose of ChAdOx1, a dose of mRNA-1273 was also more effective for improving antibody levels than ChAdOx1 (GMR = 11.09; 95% CI: 8.36-14.71) or NVX-CoV2373 (GMR = 2.87; 95% CI: 1.08-3.91). No significant difference in the risk for SAEs was found in any comparisons.
CONCLUSIONS:
Relative to vaccination with two doses of CoronaVac, a dose of BNT162b2 as a booster substantially enhances immunogenicity reactions and has a relatively acceptable risk for SAEs relative to other vaccines. For primary vaccination, schedules including mRNA vaccines induce a greater immune response. However, the comparatively higher risk for local and systemic adverse events introduced by mRNA vaccines should be noted.
