ObjectiveQi deficiency and phlegm dampness syndrome is a common type of clinical traditional Chinese medicine（TCM） syndrome. However， there is no standard， scientific， and accurate report on the construction of animal models of Qi deficiency and phlegm dampness syndrome. This study aims to construct a mouse model of Qi deficiency and phlegm dampness syndrome by using a multi-factor composite modeling method and to evaluate the model. MethodsTwenty-one C57BL/6 mice were randomly divided into three groups with seven mice in each group， which were the normal group， model group， and Shenling Baizhusan （SLBZ） group. The control group was fed with ordinary diet and kept in a normal environment. The model group and SLBZ group were fed with a high-fat diet in a high-humidity environment. Swimming with heavy weights until exhaustion and gavage with cold water or lard were used to establish the mouse model of Qi deficiency and phlegm dampness syndrome. In order to test the syndrome by prescription， mice in the SLBZ group were treated with SLBZ for 14 days after model construction. The exhaustive swimming time， body weight， serum lipid levels， tongue changes， "Qi deficiency and phlegm dampness" assessment scale score， and cecal index of mice in each group were measured. The feces of each group of mice were sent for metagenomics and metabolome sequencing， and the changes in intestinal flora and metabolites were analyzed. ResultsAfter the modeling of Qi deficiency and phlegm dampness syndrome， the exhaustive swimming time of mice was obviously shortened （P<0.01）. The serum total cholesterol， low density lipoprotein cholesterol， and non-high density lipoprotein cholesterol of mice were significantly increased （all P<0.01）. The tongue of mice was significantly different from that of the normal group， and the score of the assessment scale was significantly higher than that of the control group （P<0.01）. Cecal index decreased significantly （P<0.01）. The serum lipid level， tongue image， assessment scale score， and cecal index were reversed in the SLBZ group. Metagenomic and metabolome sequencing results showed that intestinal flora and fecal metabolites were significantly changed in mice with Qi deficiency and phlegm dampness syndrome. Akkermansia_muciniphila， Faecalibaculum_rodentium， Eubacterium_plexicaudatum， Eubacterium sp 14_2， Candida glabrata， Romboutsia_ilealis， Turicibacter sp TS3， and other bacteria had significant changes， and the expressions of intestinal metabolites such as chenodeoxycholic acid， choline， L-phenylalanine betaine， and 2-phenylbutyric acid were significantly changed. Related metabolic pathways such as linoleic acid metabolism， primary bile acid biosynthesis， lysine degradation， arginine biosynthesis， and alpha-linolenic acid metabolism were affected. ConclusionThe Qi deficiency and phlegm dampness model of mice can be constructed by the multi-factor composite modeling method of high-fat diet feeding， high-humidity environment feeding， exhaustive swimming with heavy weight， and intragastric administration with cold water or lard. The blood lipid level， tongue change， score of "Qi deficiency and phlegm dampness assessment scale"， cecal index， and changes in related intestinal flora and metabolites of mice can be used as key indicators for model evaluation.

Immune complex deposition is a critical factor in early renal damage associated with lupus nephritis (LN), and targeting plasma cell aggregation offers a promising therapeutic strategy. Ginsenoside compound K (i.e., 20-O-β-d-glucopyranosyl-20(S)-protopanaxadiol) (CK), a derivative of ginsenoside, has indicated significant potential in alleviating renal damage in lupus-prone mice, potentially by modulating B cell dynamics in response to endoplasmic reticulum (ER) stress. In this study, CK (20 or 40 mg/kg) was orally administered to female MRL/lpr mice for 10 weeks. The effects of CK on B cell subpopulations, renal function, and histopathological changes were evaluated. Single-cell ribonucleic acid sequencing was employed to analyze gene expression profile and pseudotime trajectories during B cell-mediated renal injury. Additionally, in vitro B cell assays were conducted to explore the role of the sirtuin-1 (SIRT1)-X-box binding protein 1 (XBP1) axis in ER stress. Our findings demonstrated that CK effectively reduced anti-double stranded DNA (dsDNA) antibody levels, alleviated systemic inflammation, improved renal function, and facilitated the clearance of deposited immune complexes. CK likely suppressed the unfolded protein response (UPR), delaying the differentiation of renal-activated B cells into plasma cells. It promoted B cell-specific SIRT1 activation and inhibited the splicing of XBP1 into its active form, XBP1s. CK also restored ER morphology by interacting with calmodulin (CALM) to maintain ER calcium storage, reinforcing SIRT1 functional integrity and promoting XBP1 deacetylation, thereby limiting plasma cell differentiation. In conclusion, CK mitigates plasma cell accumulation in the renal microenvironment by preventing SIRT1-mediated XBP1 splicing, offering a potential therapeutic approach for LN.

Objective:To analyze the characteristics of inhibitory control and cognitive flexibility in hearing-impaired children.Methods:From March to April 2023, a convenience sampling method was used to select 33 hearing-impaired children from a special education school in Meizhou City, Guangdong Province, and 35 normal-hearing children from two ordinary schools as participants. Inhibitory control and cognitive flexibility of the participants were assessed by the Flanker task and the dimensional change card sorting (DCCS) task. Statistical analysis was conducted using SPSS 26.0 software, and independent sample t-test was used to compare the differences in reaction time and accuracy rate between two groups of participants. Results:There were no significant differences in the Flanker task reaction time ((558.39±123.65) ms vs (566.11±118.20) ms) and accuracy rate((0.93±0.10) vs (0.96±0.04))between hearing-impaired children and normal-hearing children ( t=-0.295, -1.645, both P>0.05). The hearing-impaired children had significantly longer reaction time ((1 019.60±131.08) ms)than the normal-hearing children ((857.85±129.19) ms) ( t=4.046, P=0.001) in the DCCS task, while there was no statistically significant difference in the accuracy rate between hearing-impaired children (0.62±0.16) and normal-hearing children (0.57±0.15) ( t=-1.602, P>0.05). Conclusion:There is no difference in inhibitory control ability between hearing-impaired children and normal-hearing children, but the hearing-impaired children have a lag in cognitive flexibility.

Objective:To investigate the effects of adherent-invasive Escherichia coli ( E. coli) LF82 on the structure and function of intestinal barrier in mice with ulcerative colitis (UC). Methods:Twenty-four specific pathogen free (SPF) C57BL/6 mice were divided into UC with E. coli LF82 group, UC group and healthy control group with eight mice in each group. The UC mice model was induced by dextran sulfate sodium (DSS). One week before modeling, the mice of UC with E. coli LF82 group were intragastric administrated with 1×10 9 colony-forming unit (CFU) E. coli LF82 to colonize the bacteria strain. The effects of E. coli LF82 on colitis of mice with UC were evaluated by disease activity index (DAI), gross morphological injury score, colonic mucosal injury index (CMDI), myeoloperoxidase (MPO) activity and pathological features. The ultrastructure and the changes of cytoskeleton F-actin of mice colonic tissues were detected by transmission electron microscope (TEM) and direct immunofluorescence. The ability of colonic mucin production and degree of fibrosis were estimated by periodic acid Schiff reaction (PAS) stain and sirius red stain. T test, least significant difference, repeated measurement analysis of variance and one-way analysis of variance were used for statistical analysis. Results:On the fourth, fifth, sixth and seventh day after the modeling, the DAI scores of UC with E. coli LF82 group were all higher than those of UC group ((2.53±0.38) points vs. (2.01±0.53) points, (3.02±0.62) points vs. (2.67±0.24) points, (3.13±0.61) points vs. (2.20±0.24) points, (3.27±0.28) points vs. (2.20±0.69) points, respectively), and the differences were statistically significant ( t=3.37, 2.25, 9.56 and 10.24, all P<0.05). The gross morphological injury score of mice colon of UC with E. coli LF82 group was higher than that of UC group ((6.17±1.94) points vs. (2.83±0.98) points), and the difference was statistically significant ( t=-3.75, P<0.05). The CMDI and MPO activity of UC with E. coli LF82 group were both higher than those of UC group ((16.80±2.79) points vs. (11.80±3.11) points, (729.3±77.5) U/mg vs. (594.4±31.9) U/mg), and the differences were statistically significant ( t=-2.83; mean difference=134.82, 95% confidence interval ( CI) 72.12 to 197.51; both P<0.05). The results of TEM showed that the E. coli LF82 could invade the submucosa of colon and caused further injury of colonic tissues in mice. The distribution of cytoskeleton F-actin of mice colonic tissues changed. The results of PAS staining showed that the percentages of PAS positive cells of UC with E. coli LF82 group and UC group were both lower than that of healthy control group ((32.40±8.02)% and (41.90±8.99)% vs. (57.70±11.52)%), and the difference was statistically significant ( F=17.63, P<0.01). The percentage of PAS positive cells of UC with E. coli LF82 group was lower than that of UC group, and the difference was statistically significant (mean difference=-9.50, 95% CI -18.33 to -0.67, P<0.05). The results of sirius red staining showed that the villous epithelium of colon mucosa of UC with E. coli LF82 group was partially injured and collagen fibers hyperplasia was serious. The area ratios of collagen fiber of UC with E. coli LF82 group and UC group were both higher than that of healthy control group ((51.83±5.78)% and (37.11±5.59)% vs. (15.41±2.25) %), and the difference was statistically significant ( F=86.72, P<0.01). The area ratio of collagen fiber of UC with E. coli LF82 group was higher than that of UC group, the difference was statistically significant (mean difference=14.83, 95% CI 8.91 to 20.76, P<0.05). Conclusions:E. coli LF82 can aggravate DSS-induced colitis in UC mice, leading to changes in colon ultrastructure and cytoskeleton, it can also reduce the ability of mucus secretion of colon of mice and increase the degree of colonic tissues fibrosis.

Objective:To examine the relationship between pre-pregnancy BMI, gestational diabetes (GDM) and different indicators of childhood obesity at the age of 4.Methods:Based on Ma’anshan Birth Cohort Study, singleton children who were born in Ma’anshan of Anhui province from October 2013 to April 2015, were followed for 4 years, consecutively. During the first questionnaire survey, data including pre-pregnancy weight, height and socio-demography were collected. During 24-28 week of gestation, 75 g oral glucose tolerance test was conducted for them. Childhood height, weight, waist circumference and body composition were measured at the age of 4. Comparisons between groups were performed using chi-square test, analysis of variance or t-test. The relationship between pre-pregnancy overweight/obesity, GDM and childhood obesity-related characteristics were analyzed by logistic regression model and generalized linear model analysis. Results:The prevalence rates of overweight and obesity in children at the age of 4 were 13.08% and 6.03%, respectively. After adjustment for characteristics related to mothers and their children, significantly increased risk of obesity ( OR=3.27, 95% CI: 2.15-4.98), larger waist circumference ( OR=2.32, 95% CI: 1.72-3.14) and higher waist-to-weight ratio ( OR=2.29, 95% CI: 1.73-3.02) were seen in the offspring of women with pre-pregnancy overweight/obesity. Body composition (skeletal muscle, body fat, body fat percentage) of the offspring were strongly correlated with pre-pregnancy overweight/obesity of the mothers ( P<0.05). Maternal GDM was associated with higher risk of childhood obesity ( OR=1.78, 95% CI: 1.14-2.79), on mothers without GDM during pregnancy. However, neither larger waist circumference, or higher waist-to-weight ratio seemed to increase the risk. Moreover, maternal GDM was not associated with body composition measures (skeletal muscle, body fat, body fat percentage). Conclusion:Pre-pregnancy BMI and maternal GDM were independent risk factors for obesity in 4-year-old children, and pre-pregnancy BMI was correlated with various indicators of body composition in children.
