Objective To investigate the relationship between serum cyclophilin A(CypA),ischemia modi-fied albumin(IMA),galectin-3(Gal-3)levels and oxidative stress and cognitive impairment(CI)in patients with acute cerebral infarction(ACI)complicated with obstructive sleep apnea hypopnea syndrome(OSAHS).Methods A total of 168 patients with ACI complicated with OSAHS who were admitted to the hospital from December 2020 to October 2023 were selected,and the levels of serum CypA,IMA,Gal-3 and oxidative stress indexes[superoxide dismutase(SOD),malondialdehyde(MDA)]in patients with different severity(mild group,moderate group,severe group)were compared.The correlation between serum CypA,IMA,Gal-3 lev-els and oxidative stress indexes were analyzed by Pearson method.The incidence of CI in patients with ACI complicated with OSAHS were statistically analyzed,the levels of serum CypA,IMA and Gal-3 were com-pared between normal cognitive group and CI group,and the risk factors of CI in patients with ACI complicat-ed with OSAHS were analyzed by multivariate Logistic regression model.Results The levels of serum CypA,IMA,Gal-3 and MDA in mild group,moderate group and severe group increased in turn(P<0.05),and ser-um SOD level decreased in turn(P<0.05).Serum CypA,IMA and Gal-3 in ACI patients complicated with OSAHS were negatively correlated with SOD(P<0.05),and positively correlated with MDA(P<0.05).Of 168 ACI patients complicated with OSAHS,79 cases(47.02%)had CI and were included in the CI group.Compared with normal cognitive group,the serum levels of CypA,IMA and Gal-3 in CI group were signifi-cantly increased(P<0.05).Multivariate Logistic regression model analysis showed that apnea hypopnea in-dex(AHI)≥20 times/h,frontal and temporal lobe infarction,elevated CypA level,elevated IMA level,and el-evated Gal-3 level were risk factors for CI in ACI patients complicated with OSAHS(P<0.05).Conclusion The high expression of serum CypA,IMA and Gal-3 in patients with ACI complicated with OS-AHS is significantly correlated with oxidative stress and CI.The increase of serum CypA,IMA and Gal-3 lev-els indicates an increased risk of CI in patients with ACI complicated with OSAHS,and early detection of the three has good clinical value in evaluating the condition of patients with ACI complicated with OSAHS.

Objective:To evaluate the effects of electroacupuncture (EA) on the learning and memory function of offspring rats exposed to sevoflurane in late-pregnancy.Methods:Thirty-two SPF healthy Sprague-Dawley pregnant rats at gestational day 18, weighing 260-280 g, were assigned to 4 groups ( n=8 each) using a random number table method: control group (C group), sevoflurane group (Sev group), EA group and sham EA group (SEA group). Sev, SEA and EA groups inhaled 2.5% sevoflurane in 50% oxygen for 6 h. In EA group, Shenting, Baihui, bilateral Quchi, and bilateral Zusanli points were stimulated with an electric stimulator (disperse-dense waves, frequency 2/6 Hz, intensity 1 mA, 20 min per day for 7 consecutive days) starting on postnatal day 21, EA was performed again for 7 days after an interval of 1 day, and the EA treatment lasted for a total of 14 days. Moriss water maze test was performed at 36 days of age to detect the spatial learning and memory function. The offspring rats were sacrificed on postnatal day 42, and the hippocampal tissues were removed for calculation of the dendritic spine density of neurons (after Golgi staining) and for determination of the apoptosis rate (using flow cytometry) and the expression of the two primary forms of brain-derived neurotrophic factor (BDNF), mature (mBDNF) and pro (proBDNF), mBDNF/proBDNF ratio, tropomyosin receptor kinase B (TrkB) and p75 neurotrophin receptor (p75NTR) (by Western blot). The mBDNF/proBDNF ratio was calculated. Results:Compared with C group, the escape latency was significantly prolonged, the time of staying at the target platform quadrant was shortened, the frequency of crossing the original platform was reduced, the dendritic spine density of hippocampal neurons and mBDNF/proBDNF ratio were decreased, the expression of TrkB was down-regulated, and the expression of p75NTR was up-regulated in Sev groups ( P<0.05). Compared with the offspring rats of Sev and SEA groups, the escape latency was significantly shortened, the time of staying at the target platform quadrant was prolonged, the frequency of crossing the original platform was increased, the dendritic spine density of hippocampal neurons and mBDNF/proBDNF ratio were increased, the expression of TrkB was up-regulated, and the expression of p75NTR was down-regulated in the offspring rats of EA group ( P<0.05), and no significant change was found in the aforementioned parameters in the offspring rats of SEA group ( P>0.05). There was no significant difference in the apoptosis rate of hippocampal neurons among the offspring rats of the four groups ( P>0.05). Conclusions:EA can improve the learning and memory function of offspring rats exposed to sevoflurane in late-pregnancy, and the mechanism may be related to promoting the conversion of proBDNF to mBDNF and improving neuronal development.

Analyzing the distribution characteristics of allergen sIgE in the serum of patients with respiratory and skin mucosal diseases in Shanghai City, and to provide epidemiological characteristics and diagnostic basis for the prevention and treatment of allergic respiratory and dermo-mucous diseases in Shanghai City. Adopting cross-sectional research, a total of 3 822 patients who received treatment in Tongren Hospital, Shanghai Jiao Tong University School of Medicine from July 2022 to July 2023 due to respiratory diseases or skin and dermo-mucous symptoms were included. Among them, there were 1 456 males and 2 366 females, with an age range of 1-97 years old. The median age (interquartile range) was 33 (27, 44) years old. The sIgE was detected by using immunoblotting. Statistical analysis was conducted using SPSS 22.0 software, and the comparison of count data (rates) between groups was conducted using χ 2 test. The results showed that a total of 3 377 (88.4%) cases among 3 822 patients were at least one allergen sIgE positive, and 72.9% (2 788/3 822) of them were multiple allergies sIgE positive. The top five allergen sIgE positive rates were Dermatophagoides pteronyssinus (37.9%, 1 447/3 822), Dermatophagoides farinae (32.1%, 1 225/3 822), milk (31.7%, 1 211/3 822), fungi (28.3%, 1 080/3 822), and Blomia tropicdis (23.8%, 909/3 822), with only milk was a kind of food allergen. The highest positive rates within the respiratory system disease group or dermo-mucous disease group were also these five allergens, without any difference in disease categories. The positive rates of cat dandruff, Humulusscandens, and juniper/birch in the respiratory system disease group were significantly higher than those in the skin and mucous membrane disease group, while the positive rates of shrimp/crab were relatively low (11.3% vs 14.9%, χ 2=9.616, P=0.002). Whether in the respiratory system disease group or the dermo-mucous disease group, the positive rates of Dermatophagoides pteronyssinus in male patients were significantly higher than those of females(42.6% vs 35.7%,41.0% vs 34.4%), with statistical significance ( χ 2=12.515, P<0.001; χ 2=5.143, P=0.023), And the three allergens, Dermatophagoides farinae, cat dander, and egg white allergens are also characterized by this feature.In addition, the positive rates of milk(33.8% vs 30.1%, χ 2=3.911, P=0.048), shrimp/crab(13.2% vs 10.0%, χ 2=6.423, P=0.014) in the respiratory system disease group were higher in males than in females, while in the dermo-mucous disease group, dog dander(20.5% vs 14.6%, χ 2=6.726, P=0.010) and peanuts/soybeans(10.5% vs 6.9%, χ 2=4.698, P=0.030) showed this phenomenon. In both the respiratory system disease group and the dermo-mucous disease group, there were 6 types of inhaled allergens (Dermatophagoides pteronyssinus, Dermatophagoides farinae, Blomia tropicdis, cat dandruff, dog dander, fungi) and 4 types of food allergens (egg yolks, egg white allergens, milk, shrimp/crab). However, the positivity rate of Aspergillus fumigatus (7.2% vs 9.3% vs 10.5% vs 15.7%, χ 2=10.996, P=0.012)in the respiratory disease group and cockroaches(4.2% vs 11.3% vs 9.6% vs 16.4%, χ 2=10.237, P=0.017) in the skin and mucosal disease group was the lowest in the underage group. There are seasonal differences in the positivity rates of allergens, with most allergens having significantly higher positivity rates in summer and autumn. In conclusion, the most common allergens sIgE positive in patients with respiratory and dermo-mucous diseases in Shanghai City are Dermatophagoides pteronyssinus, Dermatophagoides farinae, milk, fungi, and Blomia tropicdis. The trend of allergen sIgE prevalence in the two major categories of diseases is basically consistent. Allergen sIgE distribution varies among patient populations of different gender, age or season, and clinical prevention and treatment can be based on the results of serum allergen testing.

【Objective】 To investigate the association between the long-stranded non-coding ribonucleic acid (lncRNA) MRAK088388 and allergic asthma in children. 【Methods】 A total of 15 healthy children and 15 children with asthma were monitored for disease progression over a 2-year period. Blood samples were collected from patients during the chronic phase of the disease for lncRNA/mRNA expression microarray analysis. Competing endogenous RNA networks (MRAK088388/miR-30a/ATG5) were identified by bioinformatics analysis. In vitro cultured bronchial epithelial (16HBE) cells were used to quantify gene and associated protein expression levels by real-time fluorescent quantitative polymerase chain reaction (qPCR) and protein blotting, respectively. Cell Counting Kit-8 and transwell assays were used to assess the proliferation and migration of 16HBE cells and verify the effects of MRAK088388, miR-30a and ATG5 on asthma. 【Results】 Six lncRNA-miRNA-mRNAs were identified by correlation analysis. By qRT-PCR analysis, MRAK088388/miR-30a/ATG5 was selected to construct the ceRNA network in this study. mRAK088388 and ATG5 expressions were high in the peripheral blood of children with asthma, while the expression of miR-30a was low (P<0.05). The expression level of E-cadherin was significantly higher in 16HBE cells after si-MRAK088388+TGF-β1 group, while the expression levels of Vimentin and α-SMA were significantly lower (P<0.05), indicating that knockdown of MRAK088388 inhibited the epithelial mesenchymal transition in 16HBE cells. Compared with si-NC+ TGF-β1 group, the cell morphology of si-MRAK088388+TGF-β1 group was similar to that of the control group, indicating that MRAK088388 knockdown attenuated TGF-β1-induced cell morphological changes; in addition, MRAK088388 knockdown inhibited TGF-β1-induced proliferation and migration of 16HBE cells. MRAK088388 was confirmed by qPCR and protein blotting to promote the progression of childhood asthma by targeting the miR-30a/ATG5 axis. 【Conclusion】 Childhood asthma is associated with the MRAK088388/miR-30a/ATG5 axis, and MRAK088388 is involved in the process of childhood allergic asthma by negatively regulating miR-30a expression and regulating elevated ATG5 expression levels to affect bronchial epithelial cell mesenchymal transition, proliferation, and migration.

Objective To investigate the long non-coding RNA(lncRNA) MRAK08838 regulates macrophage function to influence the development of asthmatic airway inflammation. Methods MRAK088388 gene knockout (MRAK088388-/-) mouse model was prepared and allergic asthma was induced by dust mite protein Dermatophagoides farinae 1 (Der f1). The mice were sacrificed after 28 days of modeling, and serum was collected to measure IgE and IgG. The FinePointe RC system was used to measure airway hyperresponsiveness and evaluate lung function in mice. Lung tissue was taken for HE staining, and periodic acid-Schiff (PAS) staining was used to evaluate inflammatory infiltration and mucus secretion in mouse lungs. Fluorescence quantitative PCR was used to detect the expression level of lncRNA MRAK08838 in bronchoalveolar lavage fluid (BALF) cells and lung tissue of asthmatic mice. ELISA was used to detect the levels of inflammatory cytokines IFN-γ, IL-4, IL-5, IL-13, IL-10 and IL-17A. Flow cytometry was used to evaluate the phenotype of macrophages in BALF and lung tissue, as well as the proportion of neutrophils, eosinophils, and alveolar macrophages. The changes of the above indicators were detected in mice by adoptive transfer of bone marrow-derived macrophages (BMDM). Results Under the challengle of Der f1, MRAK088388-/- mice showed reduced allergic airway inflammation, including reduced eosinophils in BALF and reduced production of IgE and IgG1. In addition, Der f1-treated MRAK088388-/- mice had fewer M2 macrophages than wild-type asthmatic mice. Wild-type mouse BMDM (M0) and Der f1-treated MRAK088388-/- mice also showed mild inflammatory response. Conclusion Knockout of MRAK088388 alleviates airway inflammation in asthmatic mice by inhibiting M2 polarization of airway macrophages.
