Ischemic stroke (IS) is a prevalent neurological disorder often resulting in significant disability or mortality. Resveratrol, extracted from Polygonum cuspidatum Sieb. et Zucc. (commonly known as Japanese knotweed), has been recognized for its potent neuroprotective properties. However, the neuroprotective efficacy of its derivative, (E)-4-(3,5-dimethoxystyryl) quinoline (RV02), against ischemic stroke remains inadequately explored. This study aimed to evaluate the protective effects of RV02 on neuronal ischemia-reperfusion injury both in vitro and in vivo. The research utilized an animal model of middle cerebral artery occlusion/reperfusion and SH-SY5Y cells subjected to oxygen-glucose deprivation and reperfusion to simulate ischemic conditions. The findings demonstrate that RV02 attenuates neuronal mitochondrial damage and scavenges reactive oxygen species (ROS) through mitophagy activation. Furthermore, Parkin knockdown was found to abolish RV02's ability to activate mitophagy and neuroprotection in vitro. These results suggest that RV02 shows promise as a neuroprotective agent, with the activation of Parkin-mediated mitophagy potentially serving as the primary mechanism underlying its neuroprotective effects.

Excessive levels of cadmium (Cd) in soil exert serious negative impacts on soil ecosystems. Microorganisms are a common component of soil and show great potential for mitigating soil Cd. This review summarizes the application and remediation mechanisms of microorganisms, microbial-plants, and microbial-biochar in Cd-contaminated soil. Microorganisms such as Bacillus, Acinetobacter, Pseudomonas, and arbuscular mycorrhizal fungi (AMF) can change the biological validity of Cd through adsorption, mineralization, precipitation and dissolution. Different factors such as pH, temperature, biomass, concentration, and duration have significant effects on Cd bioavailability by microorganisms. Pseudomonas, Burkholderia, and Flavobacterium can promote the uptake of Cd2+ by hyperaccumulator through promotion and activation. Biochar, a soil amendment, possesses unique physicochemical properties and could act as a shelter for microorganisms in agriculture. The use of combined microbial-biochar can further stabilize Cd compared to using biochar alone.

ObjectiveTo explore the mechanism of Danggui Niantongtang (DGNTT) against adjuvant-induced arthritis (AA) in rats with wind-dampness-heat arthralgia (FSR) based on the variation of intestinal flora. MethodA total of 60 SD rats were randomized into normal (control) group, FSR group, low-, medium-, and high-dose DGNTT (5.67, 11.34, 22.68 g·kg-1) groups, and methotrexate (MTX) group (1.35 mg·kg-1), with 10 rats in each group. The rats, except the control group, were injected with Mtb adjuvant and then exposed to artificial climatic chamber (hot and humid with wind) for 64 h for modeling. The rats were treated with water, DGNTT or MTX for 28 days from the day of injection. Arthritis index (AI) of rats was measured and paw volume was determined with a volume meter. The morphology of synovial tissues of the knees was observed based on hematoxylin-eosin (HE) staining and the changes of intestinal flora were analyzed based on 16S rRNA sequencing. ResultDGNTT can alleviate the hyperplasia of synovial tissue and inflammation of AA rats with FSR and inhibit the formation of pannus. The results of 16S rRNA sequencing showed that the relative abundance of Firmicutes, Lactobacillus, Prevotella 9, and Alloprevotella decreased (P<0.05, P<0.01) and the relative abundance of Bacteroidetes and Bacteroides increased (P<0.01) in FSR group compared those in the control group. Compared with the FSR group, all DGNTT groups and MTX group had high relative abundance of Lactobacillus (P<0.05, P<0.01) and low relative abundance of Bacteroidetes (P<0.01) and medium-dose and high-dose DGNTT groups and MTX group showed high abundance of Firmicutes, Prevotella 9, and Alloprevotella and low abundance of Bacteroides (P<0.05, P<0.01). Spearman's correlation analysis suggested that the abundance of Bacteroides and Helicobacter was in positive correlation with AI (P<0.05), while the abundance of Prevotella 9 and Candidatus Saccharimonas was in negative correlation with AI (P<0.01, P<0.05). There was a negative correlation between the abundance of Prevotella 9 and paw volume (P<0.01), and the abundance of Ruminococcaceae NK4A214 group, Christensenellaceae R-7 group, and Bacteroides was in negative correlation with spleen index (P<0.05). The abundance of Prevotella 9 was in negative correlation with spleen index (P<0.01). ConclusionDGNTT is effective for arthritis with FSR, as it can regulate the composition of intestinal flora in AA rats by increasing the abundance of probiotics and inhibiting the growth of pathogenic bacteria. The mechanism is the likelihood that it improves intestinal immune metabolism to ensure intestinal homeostasis.

OBJECTIVE: To investigate the effect of 1,2-dichloroethane(1,2-DCE) acute inhalation exposure on the differential gene expression of phase Ⅰ metabolic enzymes. METHODS: The specific pathogen free SD rats were randomly divided into control group(16 rats), low-and high-dose groups(24 rats in each group, half males and half females). Low-and high-dose group were given daily 600, 1 800 mg/m~(3 ) of 1,2-DCE, and the control group given the fresh air by dynamic inhalation for 8 hours per day for consecutive 7 days. After the end of exposure, the relative mRNA expression of cytochrome P450 2 E1(CYP2 E1), alcohol dehydrogenase(ADH1) and acetaldehyde dehydrogenase 3 alpha 1(ALDH3α1) in the liver tissue was detected by real-time fluorescence quantitative polymerase chain reaction. RESULTS: The relative expression of CYP2 E1 in male high-dose group was higher than that in male low-dose group and female high-dose group(P<0.05). The relative expression of ADH1 in male low-and high-dose groups was higher than that in male control group(P<0.05). The relative expression of ADH1 in male high-dose group was higher than that in male low-dose group and female high-dose group(P<0.05). The relative expression of ALDH3α1 in high-dose group was higher than that in control group and low-dose group(P<0.05). CONCLUSION: High dose 1,2-DCE could increase the gene expression of phase Ⅰ metabolic enzymes in rat liver. The 1,2-DCE has more obvious effect in male rats than in female rats.

Tyrosine phosphatase SHP2 is a promising drug target in cancer immunotherapy due to its bidirectional role in both tumor growth promotion and T-cell inactivation. Its allosteric inhibitor SHP099 is known to inhibit cancer cell growth both and . However, whether SHP099-mediated SHP2 inhibition retards tumor growth anti-tumor immunity remains elusive. To address this, a CT-26 colon cancer xenograft model was established in mice since this cell line is insensitive to SHP099. Consequently, SHP099 minimally affected CT-26 tumor growth in immuno-deficient nude mice, but significantly decreased the tumor burden in CT-26 tumor-bearing mice with intact immune system. SHP099 augmented anti-tumor immunity, as shown by the elevated proportion of CD8IFN- T cells and the upregulation of cytotoxic T-cell related genes including , which decreased the tumor load. In addition, tumor growth in mice with SHP2-deficient T-cells was markedly slowed down because of enhanced anti-tumor responses. Finally, the combination of SHP099 and anti-PD-1 antibody showed a higher therapeutic efficacy than either monotherapy in controlling tumor growth in two colon cancer xenograft models, indicating that these agents complement each other. Our study suggests that SHP2 inhibitor SHP099 is a promising candidate drug for cancer immunotherapy.

Objective:
To understand the current situation of toilet facilities among rural primary schools and toilet-using behavior among primary students,and to provide a reference for improving school environment.
Methods:
Totally 149 students in 2 rural non-boarding primary schools in northern China were selected. and on-site observation and questionnaire survey were used to obtain the current situation of toilet hygiene, toilet time and toilet behavior, as well as feelings towards school toilet. The results of the survey were statistically analyzed by using SAS 9.4.
Methods:
Both two schools were deep pit latrine, the number of pit in female toilets is lower than the requirements of the “Code for design of school”, and the urinal trough and the number of pit in male toilet meet the standard requirements. The average total time of toilet-using was (28.46±11.72)s for boys and (42.48±15.52)s for girls, the difference was of significant difference (t=-7.96, P<0.01). The average actual time of toilet-using is (24.27±9.13)s for boys and (24.69±9.40)s for girls, with no statistical difference. The result showed that school 2 was better than school 1 in the behavior of urinating frequency in toilet, queuing when using toilet, and the way to express needs of toilet-using in class(χ2=11.70,27.19,17.74,P<0.05); senior students use less toilets than lower grade students. The main complains for students in school toilet hygiene is its bad smell(χ2=5.28,13.18,P<0.05).
Conclusion
Primary school students in northern China always take bathroom breaks in the morning, and the average time of toilet-using is different from that of adults. Senior students are more willing to express their toilet needs than lower grade students. Students are not satisfied with the hygiene of school toilets, and the toilet experience is poor.
