Objective:To investigate the effect of insulin-like growth factor 1 (IGF-1) on acute lung injury in septic mice and its underlying molecular mechanism.Methods:Twenty SPF male C57BL/6J mice aged 6-8 weeks were randomly (random number) divided into the sham-operated group, sham-operated + IGF-1 group, sepsis group and sepsis + IGF-1 group, with 5 mice in each group. IGF-1 [60 μg/(kg·d)] was injected via the tail vein for 3 consecutive days in the sham-operated + IGF-1 group and sepsis + IGF-1 group, and mice in the sham-operated group and sepsis group were injected with an equal volume of saline. The tissue of the upper lobe of the right lung was taken to calculate the wet-to-dry ratio, and the upper lobe of the left lung was subjected to HE staining to analyze pathological changes and evaluate lung injury. The levels of interleukin (IL)-6 and IL-1β in the bronchoalveolar lavage fluid (BALF) and serum of mice were detected by ELISA. The expression of p-PI3K, PI3K, p-AKT and AKT in lung tissues was determined via Western blotting. The quantitative data with a normal distribution and homogeneity of variance were compared between the two groups by two independent sample t test. Results:Lung volume was reduced in the sepsis group than in the sham-operated group, obvious surface congestion, dark red color, large bruises and hemorrhagic foci were observed under the pericardium, and the wet-to-dry ratio was significantly elevated ( P<0.05). Compared with the sepsis group, the sepsis + IGF-1 group had slightly increased lung volume, less congestion, darker red color, fewer bruises and hemorrhagic foci, and a lower wet-to-dry ratio ( P<0.05). There was no significant change in lung tissue morphology in the sham-operated + IGF-1 group compared with the sham-operated group. HE staining and lung histopathological scores showed that lung tissue was significantly damaged in the sepsis group than the sham-operated group ( P<0.001), and the pathological score of lung tissue was less damaged in the sepsis + IGF-1 group compared with the sepsis group ( P<0.01). The ELISA results demonstrated that the serum levels of IL-6 and IL-1β were markedly decreased in the sepsis + IGF-1 group than in the sepsis group [(26.22±1.60) pg/mL vs. (45.61±7.85) pg/mL, P<0.05; (87.99±11.80) pg/mL vs. (181.26±10.11) pg/mL, P<0.001]. Moreover, the IL-6 and IL-1β contents in the BALF of the sepsis + IGF-1 group were notably lower than those in the BALF of the sepsis group [(7.67±0.42) pg/mL vs. (20.25±0.43) pg/mL, P<0.001; (17.00±6.08) pg/mL vs. (108.61±5.18), pg/mL P <0.001]. Western blot analysis revealed that the expression of p-PI3K, PI3K, p-AKT and AKT in the lung tissues of mice in the sepsis+IGF-1 group were markedly lower than that in the sepsis group [(0.71±0.05) vs. (1.21±0.09), P<0.05; (0.57±0.08) vs. (1.24±0.22), P<0.01; (0.29±0.07) vs. (1.10±0.04), P<0.001; (0.65±0.17) vs. (1.19±0.07), P<0.01]. Conclusion:IGF-1 ameliorates sepsis-induced acute lung injury in mice, and its protective effect may be achieved by inhibiting the PI3K/AKT pathway.

Objective: To explore the causal link of cumulative ecological risk and future orientation with health risk behaviors among higher vocational college students, so as to provide reference for reducing and preventing health risk behaviors among higher vocational college students. Methods: A longitudinal follow up study was conducted on 612 students using convenience sampling from 2 vocational colleges in Hunan Province. The Cumulative Ecological Risk Scale, Future Orientation Scale, and Health Risk Behavior Scale were used during three follow up visits (T1: September 2022, T2: June 2023, T3: March 2024), and a cross lagged panel model was constructed to examine the longitudinal causal relationship of cumulative ecological risk, future orientation and health risk behaviors. Analysis of longitudinal intermediary effect between variables by Bootstrap. Results: The cumulative ecological risk scores of T1, T2 and T3 among higher vocational college students were (2.94±1.44,2.99±1.63,3.02±1.54), future orientation scores (40.49±4.71,41.51±5.72,41.06±4.35) and health risk behavior scores (3.73±2.01,3.49±2.00,3.23±2.00). The results of repeated measures ANOVA showed that the future orientation score of T2 was higher than that of T1, and the main effect of measurement time was statistically significant ( F=5.09，P＜0.01,η 2=0.02). The health risk behavior score of T1 was higher than that of T2, and the health risk behavior score of T2 was higher than that of T3, and the main effect of measurement time was statistically significant ( F=10.12，P＜0.01,η 2=0.03).The cross lagged model showed good adaptability, with χ 2/df =7.20 ( P <0.01), relative fitting indicators GFI=0.98, CFI=0.99, TLI=0.96, IFI=0.99, NFI =0.99, and absolute fitting indicator RMSEA =0.06. Among them, the T1, T2 cumulative ecological risk showed negatively predictive effects on T2, T3 future orientation ( β =-0.24, -0.47 ), and T1, T2 cumulative ecological risk positively predicted T2, T3 health risk behavior ( β =0.20, 0.24), while T1, T2 future orientation negatively predicted T2, T3 health risk behavior ( β =-0.25, -0.18) ( P ＜0.01). Bootstrap test analysis found that T2 future orientation had a longitudinal mediating effect ( β=0.04, P ＜0.01) on the T1 cumulative ecological risk and T3 health risk behavior. Conclusions The accumulation of ecological risk among higher vocational college students can positively predict health risk behaviors, while future orientation can negatively predict healthrisk behaviors. Moreover, future orientation plays a longitudinal mediating role between accumulated ecological risks and health risk behaviors.

With the main pathological features of glomerulosclerosis and interstitial fibrosis， renal fibrosis is a key pathological process causing chronic kidney disease to progress to end-stage disease. As a cellular autophagic process， mitochondrial autophagy plays a crucial role in maintaining mitochondrial mass and functional stability. Mitochondrial dysfunction is considered to be one of the key factors driving the progression of fibrosis. Phosphatase and tension protein homologue （PTEN） induce various signalling pathways such as putative kinase 1/parkin， Nip3-like protein X/Bcl-2 interacting protein 3， and FUN14 structural domain-containing protein 1 to activate mitochondrial autophagy to participate in the regulation of fibrogenic factors， amelioration of oxidative stress， and inhibition of inflammatory response and apoptosis， which in turn effectively slows down the progression of renal fibrosis. Studies have shown that traditional Chinese medicine monomers and compound preparations， including phenolics， terpenoids， ketones， and alkaloids， can regulate mitochondrial autophagy-related signalling pathways and achieve significant clinical efficacy in intervening in the progression of renal fibrosis for the treatment of chronic kidney disease. This paper summarized the mechanism of mitochondrial autophagy and the research progress of traditional Chinese medicine intervention in renal fibrosis to provide new ideas for the study of the mechanism of traditional Chinese medicine in treating renal fibrosis.

ObjectiveTo establish a theoretical system of pharmacokinetic and spectrokinetic dose-time characterization of traditional Chinese medicine（TCM）. By analyzing the pharmacokinetic and spectrokinetic behaviors of Lonicerae Flos， Houttuyniae Herba injection， Lonicerae Japonicae Flosand Buyang Huanwutang， this paper compared the similarities and differences of the three methods for characterizing the dose-time relationship， namely half-life， statistical moment and statistics， in order to find the most suitable method for characterizing the relationship. MethodTen mice were randomly selected from 100 Kunming mice as the blank group， and the remaining mice were coated with xylene in the auricle to establish the acute inflammation model of ear swelling. After successful modeling， the mice were gavaged with aqueous extract of Lonicerae Flos（30 g∙kg^-1）， and the blank group was gavaged with an equal volume of normal saline. The plasma of mice was collected at different time points to determine the content changes of components. At the same time， the pharmacokinetic results of Houttuyniae Herba injection， Lonicerae Japonicae Flos and Buyang Huanwutang were included， and the pharmacokinetic and spectrokinetic parameters were calculated. Then the difference in the time of calculating 95% total component content of metabolism by half-life method， statistical moment method and statistical method was compared. ResultOn the basis of the half-life method， the mathematical expressions of statistical moment method and statistical method suitable for the characterization of dose-time relationship of multi-component system of TCM were established. The results showed that the pharmacokinetic parameters of the individual components in Lonicerae Flos varied， with cryptochlorogenic acid and rutin showing a two-compartment model and the other components showing a one-compartment model. After calculation of spectrokinetic similarity， the metabolic patterns among the components contained in Houttuyniae Herba injection， Lonicerae Japonicae Flos， Lonicerae Flos and Buyang Huanwutang were different and varied greatly in vivo. The time to metabolize 95% of the total components of the four research subjects in vivo was calculated by the half-life method， statistical moment method and statistical method， and it was found that the difference between statistical moment method and half-life method was large， and the difference between statistical moment method and statistical method was small. ConclusionStatistical method not only reflects the characteristics of statistical moment method， characterizes the dispersion degree of each component， but also can be associated with fingerprint to form spectrokinetics， characterizing the dose-time relationship of 95% of drug components， which is a more desirable method to characterize the dose-time relationship of the component groups in TCM.

Objective:To analyze the characteristics and electrogastrogram features of patients with functional dyspepsia (FD) overlapping lower gastrointestinal symptoms (LGS).Methods:The clinical data of 61 patients with FD from January 2018 to December 2020 in the First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed. Among them, FD overlapping LGS was in 33 cases (FD overlapping LGS group), and simple FD in 28 cases (simple FD group). The manifestations of patients with FD overlapping LGS were recorded. The dyspeptic symptom score was assessed using the Rome Ⅳ criteria. Anxiety and depression status were evaluated using the hospital anxiety and depression scale (HADS), and sleep disorder was assessed using the Pittsburgh sleep quality index (PSQI). The electrogastrogram was performed, and the normal slow wave percentage (N%), bradygastria percentage (B%), tachygastria percentage (T%), arrhythmia percentage (A%), dominant frequency, dominant power and postprandial-to-fasting power ratio (PR) were recorded.Results:The most common symptom in FD patients overlapping LGS was lower abdomen distention, the incidence was 84.85% (28/33). The upper abdominal bloating score in FD overlapping LGS group was significantly higher than that in simple FD group: 7.00 (6.50, 7.00) scores vs. 5.00 (0.50, 7.00) scores, and there was statistical difference ( P<0.01); there were no statistical differences in other dyspeptic symptoms scores and total score between the two groups ( P>0.05). The incidences of depression and sleep disorder in FD overlapping LGS group were significantly higher than those in simple FD group: 42.42% (14/33) vs. 14.29% (4/28) and 69.70% (23/33) vs. 39.29% (11/28), and there were statistical differences ( χ2 = 5.77 and 5.68, P<0.05); there was no statistical difference in the incidence of anxiety between the two groups ( P>0.05). In FD overlapping LGS group, the postprandial T% in the gastric fundus and postprandial A% in the gastric body were significantly lower than those before meal: 13.79% (6.79%, 21.46%) vs. 20.69% (12.45%, 27.59%) and 3.45% (0, 6.90%) vs. 6.90% (3.45%, 13.79%), and there were statistical differences ( P<0.01). In simple FD group, the postprandial N% in the gastric fundus was significantly lower than that before meal: 55.92% (43.71%, 70.02%) vs. 69.27% (48.07%, 78.45%), and there was statistical difference ( P<0.05). In the gastric fundus, the preprandial N% in FD overlapping LGS group was significantly lower than that in simple FD group, preprandial B% and T% were significantly higher than those in simple FD group, and there were statistical differences ( P<0.01 or <0.05). In the gastric body, the preprandial N% in FD overlapping LGS group was significantly lower than that in simple FD group, and there was statistical difference ( P<0.05). In the pyloric region, the PR in FD overlapping LGS group was significantly lower than that in simple FD group, and there was statistical difference ( P<0.05). In the overall stomach, the preprandial N% in FD overlapping LGS group was significantly lower than that in simple FD group, the preprandial B% and T% were significantly higher than those in simple FD group, and there were statistical differences ( P<0.01 or <0.05). Spearman correlation analysis result showed that the disease course was not correlated with electrogastrogram parameters in patients with FD overlapping LGS ( P>0.05); the total score of dyspeptic symptoms was positively correlated with postprandial A% in the overall stomach ( r = 0.345, P<0.05), and negatively correlated with postprandial dominant frequency in the overall stomach and pyloric region ( r = -0.357 and -0.473, P<0.05 or <0.01). Conclusions:FD patients can overlap with various LGS. The patients with FD overlapping LGS have more severe dyspepsia symptoms, higher proportions of comorbid depression and sleep disorders, and more severe abnormalities in fasting proximal gastric electrical rhythm and emptying function. The severity of dyspeptic symptoms in patients with FD overlapping LGS is correlated with postprandial gastric electrical rhythm abnormalities.

Objective: To explore the microbial correlation between oral tongue coating (TC) and gastric mucosa (GM) in patients with gastric intestinal metaplasia (GIM). Methods: The present study recruited 1360 volunteers for upper gastrointestinal cancer screening. The microbiota in TC and GM were profiled by long-read sequencing of full-length 16S rRNA gene. The microbial diversity, community structure, and linear discriminant analysis effect size (LEfSe) were analyzed by the software Visual Genomics. SparCC correlation analysis was used to construct the commensal network and the graphical display was conducted by R software. Results: The population included 44 patients with precancerous GIM, and 28 matched controls with negative rapid urease test (RUT) and non-symptomatic chronic superficial gastritis (CSG). No significant difference in diversity was observed between GIM patients and controls in TC or GM microbiota (P > 0.05). Patients had a higher percentage of 41 – 60 co-occurring operational taxonomic units (OTUs) between TC and GM than controls (34.1% vs. 25.0%) (P < 0.05). The LEfSe showed that TC Prevotella melaninogenica and three gastric Helicobacter species (i.e., Helicobacter pylori, Helicobacter pylori XZ274, and Helicobacter pylori 83) were enriched in patients with GIM. Furthermore, GIM patients with positive RUT had a lower percentage of co-occurring OTUs over 20 (P < 0.05), and lower abundances of gastric Veillonella, Pseudonocardia, and Mesorhizobium than those with negative RUT (P < 0.05). The commensal network between TC and GM was more complex in GIM patients than in controls. GIM patients with positive RUT demonstrated more bacterial correlations between TC and GM than those with negative RUT. Finally, the serum ratio of PG-I/II was negatively correlated with three gastric Helicobacter species (Helicobacter pylori, Helicobacter pylori XZ274, and Helicobacter pylori 83) in patients with negative RUT (P < 0.05), and negatively correlated with two TC species (Fusobacterium nucleatum subsp. nucleatum and Campylobacter showae) in patients with positive RUT (P < 0.05). Conclusion The development of GIM potentiated the commensal network between oral TC and GM, providing microbial evidence of the correlation between TC and the stomach.
