ObjectiveTo investigate the effects of maltol aluminum exposure on miR-193a-3p, demethylase AlkB homolog 5 (ALKBH5), phosphatase and tensin homolog deleted on chromosome ten (PTEN) and protein kinase B (AKT), and whether miR-193a-3p is involved in aluminum-induced cognitive impairment by regulating ALKBH5/PTEN/AKT signaling pathway. Methods Specific pathogen-free male SD rats were randomly divided into control group and low-, medium- and high- dose groups according to their body weight, with eight rats in each group. Rats in the low-, medium-, and high- dose groups were intraperitoneally injected with maltol aluminum solution at concentrations of 10.00, 20.00, and 40.00 μmol/kg body weight, respectively, while the rats in control group were given an equal volume of 0.9% sodium chloride solution. Rats were injected for five days every week for three months. After injection, the novel object recognized test was used to assess the learning and memory ability of the rats. The relative expression of miR-193a-3p and B-cell lymphocytoma-2 (Bcl-2), Bcl-2 associated X protein (Bax) and cysteine aspartate protease-3 (Caspase-3) mRNA in rat hippocampus was detected using the real-time quantitative polymerase chain reaction. The relative protein expression of ALKBH5, PTEN, and AKT2 in the rat hippocampus was detected using Western blot. Results The discrimination index and the preference index of the new object recognition test of the rats in high-dose group were lower than those in control group and low-dose group (all P<0.05). The relative expression of miR-193a-3p and Bcl-2 mRNA in the hippocampus of the rats in high-dose group was lower than those in control group and low-dose group (all P<0.05). The relative mRNA expression of Bax in the high-dose group was higher than those in the control group and low-dose group (both P<0.05). The relative mRNA expression of Caspase-3 of the rats in the high-dose group was higher than that in the other three groups (both P<0.05). The relative protein expression of ALKBH5 in the hippocampus of the rats in the high-dose group was lower than that in the control group (P<0.05). The relative expression of PTEN protein was higher than those in the control group and low-dose group (both P<0.05). The relative protein expression of AKT2 was lower than those in the control group and low-dose group (both P<0.05). Conclusion Sub-chronic aluminum exposure can inhibit the expression of miR-193a-3p in the hippocampus of rats, which may disrupt the ALKBH5/PTEN/AKT pathway and affect normal neuronal homeostasis and cellular function. This pathway may play an important role in aluminum-induced cognitive impairment.

Objective To investigate the clinical efficacy of mitral valve repair technique in the treatment of rheumatic mitral valve lesions. Methods The clinical data of patients diagnosed with rheumatic mitral valve lesions and undergoing mitral valve repair under extracorporeal circulation in our department from 2021 to 2022 were retrospectively analyzed. Results A total of 100 patients were collected, including 78 females and 22 males with an average age of 52 years. There were no secondary open heart or death in the whole group. Extracorporeal circulation time was 136.3±33.1 min, aortic cross-clamping time was 107.6±27.5 min, ventilator use time was 12.9±5.9 h, ICU stay was 2.6±1.4 d, and vasoactive medication use was 823.4±584.4 mg. Before and after the surgery, there were statistical differences in the left ventricular end diastolic diameter, left atrial end systolic diameter, effective mitral valve orifice area, shortening rate of left ventricular short axis, mitral E-peak blood flow velocity, mean mitral transvalvular pressure difference, mitral pressure half-time, and cardiac function graded by New York Heart Association (P<0.05). While there was no statistical difference in left ventricular ejection fraction or left ventricular end-diastolic volume (P>0.05). Conclusion Overall repair of rheumatic mitral valve lesions can significantly improve the cardiac function and hemodynamics of the patients, and is a good choice for patients with rheumatic mitral valve lesions.

Japanese encephalitis is an acute central nervous system infectious disease caused by Japanese encephalitis virus (JEV) with brain parenchyma inflammation, characterized by high fever, headache, positive meningeal irritation, impaired consciousness, convulsion, and respiratory failure, with mortality rate as high as 20%-30%, and with neurological sequelae in 30%-50% of survivors. The mechanism of brain damage caused by JEV infection is still unclear, and some studies imply its close relation with immune-inflammatory response. This article reviews the research progress on immune-inflammatory response mechanism of Japanese encephalitis to help to understand its pathogenesis.

It is discovered that activated caspase-3 tends to induce apoptosis in gasdermin E (GSDME)-deficient cells, but pyroptosis in GSDME-sufficient cells. The high GSDME expression and apoptosis resistance of pancreatic ductal adenocarcinoma (PDAC) cells shed light on another attractive strategy for PDAC treatment by promoting pyroptosis. Here we report a hGLuc-hGSDME-PCA system for high-throughput screening of potential GSDME activators against PDAC. This screening system neatly quantifies the oligomerization of GSDME-N to characterize whether pyroptosis occurs under the stimulation of chemotherapy drugs. Based on this system, ponatinib and perifosine are screened out from the FDA-approved anti-cancer drug library containing 106 compounds. Concretely, they exhibit the most potent luminescent activity and cause drastic pyroptosis in PDAC cells. Further, we demonstrate that perifosine suppresses pancreatic cancer by promoting pyroptosis via caspase-3/GSDME pathway both in vitro and in vivo. Collectively, this study reveals the great significance of hGLuc-hGSDME-PCA in identifying compounds triggering GSDME-dependent pyroptosis and developing promising therapeutic agents for PDAC.

Objective:
To evaluate and compare a series of volume changes in the nasal cavity (NC), nasopharynx, oropharynx, and maxillary sinuses (MS) in growing Class III patients after either rapid palatal expansion (RPE) or alternate rapid maxillary expansion and constriction (Alt-RAMEC) followed by facemask (FM) therapy, by using conebeam computed tomography (CBCT).
Methods:
Forty growing Class III patients were retrospectively selected and divided into two matched groups: RPE/FM (14 females, 6 males; mean age, 9.66 ± 1.23 years) and Alt-RAMEC/FM groups (14 females, 6 males; mean age, 10.28 ± 1.45 years). The anteroposterior and vertical displacements of Point A, the volumes of the NC, nasopharyngeal, oropharyngeal, and MS were measured at different time points: pretreatment (T1), postexpansion (T2), and postprotraction (T3).
Results:
Both groups demonstrated significant maxilla advancement (by 1.3 mm) during expansion, with a statistically significant intergroup difference during protraction (RPE/FM, 1.1 mm; Alt-RAMEC/FM, 2.4 mm; p < 0.05) and throughout the treatment (RPE/FM, 2.4 mm; Alt-RAMEC/FM, 3.7 mm; p < 0.05). NC and nasopharyngeal airway volumes increased significantly in both groups after expansion, protraction, and treatment. The oropharyngeal and MS volumes increased in both groups after protraction and post-treatment. However, no volumetric differences were observed between the two groups.
Conclusions
There was no significant difference in airway volume changes, including NC, nasopharyngeal, oropharyngeal airway, and MS, between RPE/FM and Alt-RAMEC/FM groups at different time points. Although there was significantly more forward movement after protraction in the Alt-RAMEC/FM group, the difference was deemed too small to be clinically relevant.
