BACKGROUND:Spleen has the functions of blood storage,hematopoiesis,and immunity.With the increase of age,the structural degeneration and functional decline of spleen lead to the impairment of immune system function,thus accelerating the aging process of the body.The treatment of spleen aging in tree shrews with highly active umbilical cord mesenchymal stem cells has not been reported. OBJECTIVE:To explore the intervention effect and mechanism of highly active umbilical cord mesenchymal stem cells on spleen aging in tree shrews. METHODS:Highly active umbilical cord mesenchymal stem cells were isolated,cultured,and obtained from the umbilical cord tissue of newborn tree shrews by caesarean section.The differentiation abilities of adipogenesis,osteogenesis,and chondrogenesis were detected by three-line differentiation kit.Cell cycle and surface markers were detected by flow cytometry.The second generation of highly active umbilical cord mesenchymal stem cells were transfected with Genechem Green Fluorescent Protein with infection complex values of 100,120,140,160,180,and 200,respectively,to screen the best transfection conditions.After transfection,the fourth generation of highly active umbilical cord mesenchymal stem cells was injected into the tail vein of tree shrews in the elderly treatment group.The young control group and the aged model group were not given special treatment.After 4 months of treatment,the spleen tissue was taken and the structure of the spleen was observed by hematoxylin-eosin staining.β-Galactosidase staining was used to detect the activity of aging-related galactosidase.Immunohistochemical staining was used to detect the expression levels of p21 and p53 proteins.Ki67 and PCNA immunofluorescence staining was used to detect cell proliferation activity.Immunofluorescence staining was used to detect the expression levels of spleen autophagy protein molecules Beclin 1 and APG5L/ATG5.Reactive oxygen species fluorescence staining was used to detect the content of reactive oxygen species in spleen tissue.CD3 immunofluorescence staining was used to detect the change of the proportion of total T lymphocytes.The secretion levels of interleukin 1β and transforming growth factor β1 in spleen were detected by enzyme linked immunosorbent assay.The distribution of highly active umbilical cord mesenchymal stem cells labeled with green fluorescent protein in spleen tissue was observed by DAPI double staining of nucleus. RESULTS AND CONCLUSION:(1)Highly active umbilical cord mesenchymal stem cells grew in a short spindle shape with fish-like growth,with a large proportion of G0/G1 phase,and had the potential to differentiate into adipogenesis,osteogenesis,and chondrogenesis.(2)Multiplicity of infection=140 and transfection for 72 hours were the best conditions for labeling tree shrews highly active umbilical cord mesenchymal stem cells with Genechem Green Fluorescent Protein.(3)Compared with the aged model group,in the aged treatment group,the spleen tissue cells of tree shrews were arranged closely,and the area of white pulp was increased(P<0.01);the boundary between red pulp and white pulp was clear;the proportion of germinal centers did not show statistically significant difference(P>0.05).The activity level of galactosidase related to spleen tissue aging was decreased(P<0.001),and the expression levels of aging protein molecules p21 and p53 were down-regulated(P<0.001).The expression levels of proliferation-related molecules Ki67 and PCNA were up-regulated(P<0.001,P<0.05);expression levels of autophagy-related molecules Beclin 1 and APG5L/ATG5 were up-regulated(P<0.001),and the content of reactive oxygen species decreased(P<0.001),and the proportion of CD3+T cells increased(P<0.05).The secretion level of interleukin 1β in the aging-related secretion phenotype decreased(P<0.001);no significant difference was found in transforming growth factor β1 level(P>0.05).Compared with the young control group,the above indexes were significantly different in the elderly treatment group(P<0.05).(4)Green fluorescent cells labeled with green fluorescent protein were observed in spleen tissue of tree shrews the elderly treatment group by frozen tissue section observation.The results show that intravenous infusion of highly active umbilical cord mesenchymal stem cells can migrate to spleen tissue,inhibit the production of reactive oxygen species,down-regulate the expression of aging-related proteins,induce autophagy,promote cell proliferation,reduce chronic inflammation,and then improve the structure and function of spleen tissue.

Objective To investigate the correlation between spread through air space (STAS) of sub-centimeter non-small cell lung cancer and clinical characteristics and radiological features, constructing a nomogram risk prediction model for STAS to provide a reference for the preoperative planning of sub-centimeter non-small cell lung cancer patients. Methods The data of patients with sub-centimeter non-small cell lung cancer who underwent surgical treatment in Nanjing Drum Tower Hospital from January 2022 to October 2023 were retrospectively collected. According to the pathological diagnosis of whether the tumor was accompanied with STAS, they were divided into a STAS positive group and a STAS negative group. The clinical and radiological data of the two groups were collected for univariate logistic regression analysis, and the variables with statistical differences were included in the multivariate analysis. Finally, independent risk factors for STAS were screened out and a nomogram model was constructed. The sensitivity and specificity were calculated based on the Youden index, and area under the curve (AUC), calibration plots and decision curve analysis (DCA) were used to evaluate the performance of the model. Results A total of 112 patients were collected, which included 17 patients in the STAS positive group, consisting of 11 males and 6 females, with a mean age of (59.0±10.3) years. The STAS negative group included 95 patients, with 30 males and 65 females, and a mean age of (56.8±10.3) years. Univariate logistic regression analysis showed that male, anti-GAGE7 antibody positive, mean CT value and spiculation were associated with the occurrence of STAS (P<0.05). Multivariate regression analysis showed that associations between STAS and male (OR=5.974, 95%CI 1.495 to 23.872), anti-GAGE7 antibody positive (OR=11.760, 95%CI 1.619 to 85.408) and mean CT value (OR=1.008, 95%CI 1.004 to 1.013) were still significant (P<0.05), while the association between STAS and spiculation was not significant anymore (P=0.438). Based on the above three independent predictors, a nomogram model of STAS in sub-centimeter non-small cell lung cancer was constructed. The AUC value of the model was 0.890, the sensitivity was 76.5%, and the specificity was 91.6%. The calibration curve was well fitted, suggesting that the model had a good prediction efficiency for STAS. The DCA plot showed that the model had a good clinically utility. Conclusion Male, anti-GAGE7 antibody positive and mean CT value are independent predictors of STAS positivity of sub-centimeter non-small cell lung cancer, and the nomogram model established in this study has a good predictive value and provides reference for preoperative planning of patients.

Objective:
To assess the awareness and associated factors of wild mushroom poisoning among students in Guizhou Province, so as to provide a scientific foundation for wild mushroom poisoning prevention and control among students.
Methods:
By a multi stage stratified cluster random sampling method, 1 162 students from Guizhou Province were selected in May 2024. The questionnaire survey was administered to evaluate knowledge regarding wild mushroom poisoning. Data were analyzed employing the χ 2 test and Logistic regression model.
Results:
Among the nine questions assessing awareness of wild mushroom poisoning, only three had the awareness rate exceeding 70%. Binary Logistic regression analysis revealed that students who "actively learn about the prevention of wild mushroom poisoning" ( OR=0.48, 95%CI =0.26-0.92) and "spread knowledge about wild mushroom poisoning to others" ( OR=0.47, 95%CI =0.33-0.69) scored higher on the wild mushroom poisoning knowledge questions ( P <0.05). Conversely, students with a habit of consuming wild mushrooms ( OR=1.52, 95%CI =1.15-2.02) scored lower ( P < 0.05 ). 42.3% of the students suggested that scientific dissemination and publicity about wild mushrooms should be intensified.
Conclusions
The awareness rate of wild mushroom poisoning knowledge among students in Guizhou Province requires further attention. Comprehensive knowledge should be disseminated systematically through various channels to further improve students awareness of the prevention and control of wild mushroom poisoning.

ObjectiveTo unveil the mechanism of Jianpi Huogu prescription (JPHGP) in ameliorating the dyslipidemia of steroid-induced osteonecrosis of the femur head (SONFH) by oxylipidomics combined with transcriptomics. MethodsSixty SD rats were assigned into normal, model, low-, medium-, and high-dose (2.5, 5, 10 g·kg-1, respectively) JPHGP, and Jiangushengwan (1.53 g·kg-1) groups. Lipopolysaccharide was injected into the tail vein at a dose of 20 μg·kg-1 on days 1 and 2, and methylprednisolone sodium succinate was injected at a dose of 40 mg·kg-1 into the buttock muscle on days 3 to 5. The normal group received an equal volume of normal saline. Drug administration by gavage began 4 weeks after the last injection, and samples were taken after administration for 8 weeks. Hematoxylin-eosin staining was conducted to reveal the histopathological changes of the femoral head, and the number of adipocytes, the rate of empty bone lacunae, and the trabecular area were calculated. Micro-computed tomography was used for revealing the histological and histomorphometrical changes of the femoral head. Enzyme-linked immunosorbent assay was employed to measure the serum levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), apolipoprotein A1 (ApoA1), and apolipoprotein B (ApoB). At the same time, the femoral head was collected for oxylipidomic and transcriptomic detection. The differential metabolites and differential genes were enriched and analyzed, and the target genes regulating lipid metabolism were predicted. The predicted target proteins were further verified by molecular docking, immunohistochemistry, and Western blot. ResultsCompared with the normal group, the model group showcased thinning of the femoral head, trabecular fracture, karyopyknosis, subchondral cystic degeneration, increases in the number of adipocytes and the rate of empty bone lacunae (P<0.01), a reduction in the trabecular area (P<0.01), decreases in BMD, Tb.Th, Tb.N, and BV/TV, and increases in Tb.Sp and BS/BV (P<0.01). Compared with the model group, the JPHGP groups showed no obvious thinning of the femoral head or subchondroidal cystic degeneration. The high- and medium-dose JPHGP groups presented declines in the number of adipocytes and the rate of empty bone lacunae, an increase in the trabecular area (P<0.05, P<0.01), rises in BMD, Tb.Th, Tb.N, and BV/TV, and decreases in Tb.Sp and BS/BV (P<0.05, P<0.01). Compared with the normal group, the model group showcased raised serum levels of TG, TC, LDL, and ApoB and lowered serum levels of HDL and ApoA1 (P<0.01). Compared with the model group, the JPHGP groups had lowered serum levels of TG, TC, LDL, and ApoB (P<0.05, P<0.01) and a risen serum level of ApoA1 (P<0.05, P<0.01). Moreover, the serum level of HDL in the high-dose JPHGP group increased (P<0.01). A total of 19 different metabolites of disease set and drug set were screened out by oxylipidomics of the femoral head, and 119 core genes with restored expression were detected by transcriptomics. The enriched pathways were mainly concentrated in inflammation, lipids, apoptosis, and osteoclast differentiation. Molecular docking, immunohistochemistry, and Western blot results showed that compared with the normal group, the model group displayed increased content of 5-lipoxygenase (5-LO) and peroxisome proliferator-activated receptor γ (PPARγ) in the femoral head (P<0.01). Compared with the model group, medium- and high-dose JPHGP reduced the content of 5-LO and PPARγ (P<0.05, P<0.01). ConclusionJPHGP can restore the levels of oxidized lipid metabolites by regulating the 5-LO-PPARγ axis to treat SONFH in rats. Relevant studies provide experimental evidence for the efficacy mechanism of JPHGP in the treatment of SONFH.

ObjectiveTo observe the clinical efficacy and relative mechanism of the Modified Wenshen Yixin Formula (温肾益心方加减, MWYF) as an auxiliary treatment of coronary heart disease (CHD) complicated with hypothyroidism of spleen-kidney yang deficiency. MethodsA total of 135 CHD patients complicated with hypothyroidism and spleen-kidney yang deficiency were included and divided into control group (67 cases) and experimental group (68 cases) according to the patients' wishes of herbal medicine administration. The control group was given conventional western medicine, while the treatment group was additionally given MWYF, 1 dose per day; both groups were treated for 8 weeks. The traditional Chinese medicine (TCM) syndrome scores, angina scores, SF-36 scores, thyroid function indicators including thyroid stimulating hormone (TSH), thyroxine (T4) and triiodothyronine (T3), as well as serum cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP), monocyte chemoattractant ligand 2 (CCL2), and tumor necrosis factor-related activator protein (CD40L) levels before and after treatment were compared between the two groups. The dosage and reduction and discontinuation rate of thyroid hormone preparations after treatment were compared between the two groups. The effectiveness regarding TCM syndrome and angina pectoris was evaluated, and the safety was assessed. ResultsBias was adjusted by matching on propensity score, and 102 cases were finally included in the statistical analysis, with 51 cases in each group. The total effective rate regarding TCM syndrome [94.12% (48/51) versus 64.71% (33/51)], the total effective rate regarding angina pectoris [80.39% (41/51) versus 62.75% (32/51)], and the reduction and discontinuation rate of thyroid hormone preparation [39.21% (20/51) versus 5.88% (3/51)] were significantly higher in the experimental group than those in the control group (P<0.05 or P<0.01). After treatment, the total TCM syndrome score, individual scores of major symptoms , the major symptoms score, the secondary symptoms score, angina pectoris score, and TSH level were significantly reduced (P<0.01), while all dimensions of SF-36 scores, T4, T3, and cAMP levels significantly increased in both groups (P<0.05 or P<0.01). The dosage of thyroid hormone preparations and the levels of cGMP, CCL2, and CD40L in the experimental group significantly decreased after treatment (P<0.01). When compared between the two groups after treatment, the total TCM syndrome score, the major symptoms score, the scores of individual major symptom (chest tightness, chest pain, fear of cold, cold limbs, waist and kness soreness and weakness), the secondary symptoms score, angina pectoris score, TSH, cGMP, CCL2, and CD40L levels of the experimental group were significantly lower than those of the control group (P<0.05 or P<0.01), while all dimension scores of SF-36, T4, T3, and cAMP levels were significantly higher (P<0.01). A total of three adverse events occurred during treatment, none of which were judged to be related to the interventions of this study. ConclusionMWYF can significantly ameliorate the TCM syndrome, angina pectoris, quality of life and thyroid function in CHD patients complicated with hypothyroidism and spleen-kidney yang deficiency, and can promote the reduction and disconti-nuation of thyroid hormone preparations. The mechanism may be related to the regulation of cAMP/cGMP balance, the regulation of hypothalamic-pituitary-thyroid metabolic axis and the reduction of immune inflammation.

OBJECTIVE
To establish UHPLC-ELSD fingerprint and multi-component content determination methods, compare the differences in sheep bile from different regions, and conduct antioxidant activity research to provide a basis for the in-depth development and utilization of sheep bile.
METHODS
Used UHPLC-ELSD method to establish 21 batches of bile fingerprints of sheep from different origins and conduct similarity analysis. Measured the content of 6 components, DPPH and ABTS free radical scavenging ability, iron ion reduction ability, and conducted entropy weighted TOPSIS and grey correlation analysis.
RESULTS
A total of 11 common peaks were identified in the fingerprint spectra of 21 batches of sheep bile. Through comparison with the control sample, 6 components were identified, including taurocholic acid(TCA), glycocholic acid(GCA), taurochenodeoxycholic acid(TCDCA), tauroursodeoxycholic acid(TDCA), glycodeoxycholic acid(GDCA), and cholic acid(CA). Except for 4 batches of samples, the similarity of the fingerprint spectra was greater than 0.90. The total content range of 6 components in the freeze-dried powder of 21 batches of sheep bile was 55.34% to 86.08%. The highest content of taurocholic acid ranged from 34.74% to 60.86%, indicating significant differences in the content of the six components in samples from different regions. Sheep bile from different regions had antioxidant activity, and there were also certain differences. The results of entropy weighted TOPSIS analysis using six component contents as variables showed that the top ten scoring groups were S2, S18, S16, S9, S8, S21, S1, S10, S20, and S15, indicating good quality and slightly better bile quality from sheep in the northern region. The grey correlation analysis results between the content of 6 components and 3 antioxidant indicators showed that all 6 components were correlated with each antioxidant indicator, and TCA, TDCA, and TCDCA had the highest correlation, which might be important components for sheep bile to exert antioxidant effects.
CONCLUSION
The use of entropy weighted TOPSIS and grey correlation analysis methods can effectively analyze the quality differences and antioxidant active components of sheep bile from different regions, providing scientific basis for its quality evaluation.

ObjectiveTo investigate the influencing factors for rebleeding after endoscopic therapy and the effect of the number of sequential treatment sessions on postoperative rebleeding in patients with liver cirrhosis receiving secondary prevention of gastroesophageal varices (GOV). MethodsA total of 1 717 patients with liver cirrhosis who received secondary prevention of GOV and attended The 960th Hospital of the PLA Joint Logistice Support Force from January 2017 to December 2021 were enrolled, and according to the presence or absence of bleeding after endoscopic therapy, they were divided into non-bleeding group and rebleeding group. The influencing factors for rebleeding were analyzed, as well as the association between the number of endoscopic treatment sessions and rebleeding. The chi-square test was used for comparison of categorical data between groups; the independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between the two groups; the Kruskal-Wallis H test was used for comparison bertween multiple groups, and the Wilcoxon test was used for further comparison between two groups. The Cox regression model was used to investigate the influencing factors for rebleeding, and the Kaplan-Meier method was used to plot survival curves, while the Log-rank test was used for comparison between groups. ResultsOf all patients, 286 (16.7%) experienced rebleeding after endoscopic therapy, and 1 431 (83.3%) did not experience bleeding. There were significant differences between the two groups in history of smoking and drinking, etiology of liver cirrhosis, hemoglobin (Hb), prothrombin time (PT), prothrombin activity (PTA), international normalized ratio (INR), albumin (Alb), fasting blood glucose, blood urea nitrogen, Child-Pugh class, aspartate aminotransferase-to-platelet ratio index (APRI) score, albumin-bilirubin (ALBI) score, use of non-selective beta-blocker (NSBB) before surgery, treatment modality, type of varices, and maximal varicose vein diameter (all P<0.05). The univariate Cox regression analysis showed that in the patients with liver cirrhosis who received secondary prevention of GOV, rebleeding was associated with history of smoking and drinking, etiology of liver cirrhosis, use of NSBB before surgery, treatment modality, maximal varicose vein diameter, Hb, platelet count, PT, PTA, INR, Alb, total bilirubin (TBil), alkaline phosphatase (ALP), gamma-glutamyl transpeptidase, blood glucose, Child-Pugh class, and ALBI score (all P<0.05). The multivariate Cox regression analysis showed that Hb (hazard ratio [HR]=0.989, 95% confidence interval [CI]: 0.983 — 0.994, P<0.001), TBil (HR=1.020, 95%CI: 1.006 — 1.034, P=0.005), Alb (HR=0.868, 95%CI: 0.758 — 0.994, P=0.041), treatment modality (sclerosing agent: HR=2.158, 95%CI: 1.342 — 3.470, P=0.002; tissue adhesive: HR=2.709, 95%CI: 1.343 — 5.462, P=0.005; ligation+sclerosing agent: HR=3.181, 95%CI: 1.522 — 6.645, P=0.002; sclerosing agent+tissue adhesive: HR=1.851, 95%CI: 1.100 — 3.113, P=0.020), ALP (HR=1.003, 95%CI: 1.001 — 1.004, P=0.002), and maximal varicose vein diameter (HR=1.346, 95%CI: 1.119 — 1.618, P=0.002) were independent influencing factors for rebleeding after endoscopic therapy. Comparison of rebleeding rate after different numbers of sequential treatment sessions showed that the patients treated for three sessions had a significantly lower rebleeding rate than those treated for one or two sessions (χ2=8.643 and 5.277, P=0.003 and 0.022). The survival analysis showed that with the increase in the number of treatment sessions, there was a significantly longer interval between rebleeding (P=0.006) and a significantly lower mortality rate (P<0.001). ConclusionThe levels of TBil, ALP, Hb, and Alb on admission, endoscopic treatment modality, and maximal varicose vein diameter were the main predictive factors for rebleeding after endoscopic therapy for GOV in liver cirrhosis, and such predictive factors should be closely monitored in clinical practice. Regular endoscopic therapy can reduce the rebleeding and mortality rates of patients with liver cirrhosis and GOV and prolonmg the interval between rebleeding.
