ObjectiveTo explore the changes in color， odor and chemical components during wine-processing of Chuanxiong Rhizoma（CR）， identify differential markers， and provide a basis for standardizing the process and establishing quality standards. MethodsFifteen batches of CR samples from 4 producing areas were collected. Colorimeter and electronic nose were used to detect the color changes and odor components of CR before and after wine-processing. Multivariate statistical methods including partial least squares-discriminant analysis（PLS-DA）， principal component analysis（PCA）， discriminant factor analysis（DFA） and Fisher discriminant analysis were applied to identify wine-processed CR at different processing stages and establish discriminant models， and differential components were screened out based on variable importance in the projection（VIP） value1. Then， high performance liquid chromatography（HPLC） was employed to detect the content changes of four components（ferulic acid， senkyunolide I， senkyunolide A and ligustilide） during the processing stages. ResultsThe differences of wine-processed CR at various stages were primarily reflected in color parameters L^*（brightness value）， a^*（red-green value） and b^*（yellow-blue value）. Based on chromaticity differences， the color reference ranges were established for moderately processed CR， including L^* of 46.75-48.24， a^* of 5.37-6.07 and b^* of 20.32-21.70. In odor analysis， DFA revealed significant differences among processing stages， and 11 odor markers were identified， with four differential markers（4-hydroxy-3-butylphthalide， isopropyl butyrate， L-limonene and 1-methoxyhexane） based on VIP values. HPLC results showed that there was no significant difference of the four components except for ligustilide in wine-processed CR at different stages. ConclusionThis study achieved rapid identification of wine-processed CR with different processing degrees by electronic sensory technology and differential component content detection， with discrimination accuracy rates of 92.4% and 93.272% for color and odor， respectively. This paper also established the reference ranges of main colorimetric parameters for wine-processed CR at different stages， and four differential components were screened out， providing a basis for standardizing the processing of wine-processed CR and establishing quality standards for this decoction pieces.

Objective: : Baculovirus inhibitory of apoptosis repeat-containing 5 (BIRC5) is critically implicated in various types of tumors. However, the specific mechanisms by which it operates in glioma are yet to be fully understood. Methods: : The data sourced from The Cancer Genome Atlas and Gene Expression Omnibus were merged and analyzed using the R software to investigate the relationship between BIRC5 expression and prognosis and diagnosis outcomes. This exploration was conducted utilizing various biological information repositories. The correlation between BIRC5 and immunity was obtained based on TIMER and TISIDB databases. Results: : Gliomas displayed a markedly elevated level of BIRC5 expression compared to adjacent tissues. Patients with glioma who exhibit elevated levels of BIRC5 experience poorer prognoses and shorter survival times. Subgroup classification further revealed that heightened expression of BIRC5 led to diminished overall survival. Analysis of logistic regression and COX indicated that expression of BIRC5 serves as a risk factor in glioma development. Functional enrichment pathways showed that the 72 hub genes related to BIRC5 were mainly closely related to nuclear division, spindle, tubulin binding, and cell cycle in glioma patients. BBIRC5 methylation suggested that BIRC5 might influence the immune response regulation and the tumor microenvironment within gliomas. BIRC5 is associated with many chemicals. Additionally, studies conducted using cell experiments and pathological sections have consistently shown that BIRC5 expression is higher in tumor cells compared to normal cells and tissues. Conclusion : BIRC5 holds promise as a valuable tool in the diagnosis, prognosis, and management of gliomas.

Objective:To investigate the clinical effects and advantages of laparoscopic total mesorectal excision in the treatment of colorectal cancer.Methods:A total of 82 patients with colorectal cancer who received treatment at the Second Affiliated Hospital of Guizhou Medical University from January 2020 to January 2023 were selected for a prospective study. They were randomly assigned to two groups using a random number table, with 41 cases in each group. The control group underwent conventional laparotomy, while the observation group received laparoscopic total mesorectal excision. Clinical efficacy, clinical indicators, and immune function indicators were compared between the two groups.Results:The operation time for patients in the observation group was (1.98 ± 0.31) hours, the length of hospital stay was (8.32 ± 2.38) days, the recovery time for bowel function was (2.15 ± 0.34) days, and the intraoperative blood loss was (112.35 ± 12.66) mL, all of which were shorter and lower than those in the control group [(2.46 ± 0.32) hours, (14.52 ± 2.42) days, (3.25 ± 0.15) days, and (167.78 ± 12.35) mL, t = 6.90, 11.70, 18.95, 20.07, all P < 0.001). The short-term response rate in the observation group was higher than that in the control group ( χ2 = 4.10, P < 0.05). The immune function indicators in the observation group, including the CD4 +/CD8 + ratio (1.78 ± 0.54), immunoglobulin A [(3.87 ± 0.73) g/L], and immunoglobulin G [(11.83 ± 2.88) g/L], were all better than those in the control group [(1.36 ± 0.53), (1.78 ± 0.63) g/L, (6.37 ± 2.45) g/L, t = 3.55, 13.88, 9.25, all P < 0.001]. The incidence of complications in the observation group was 2.44% (1/41), which was significantly lower than that in the control group [19.51% (8/41), χ2 = 4.49, P < 0.05]. Conclusions:Laparoscopic total mesorectal excision for patients with colorectal cancer has significant advantages, including faster recovery, less bleeding, and fewer complications, making it more superior to conventional laparotomy.

Objective To explore the effect of collateral status on prognosis in elderly patients with acute ischemic stroke due to large vessel occlusion(AIS-LVO)after Solitaire stent retriever in combination with the intracranial support catheter aspiration for mechanical thrombectomy(SWIM),and construct a prediction model for prognosis.Methods A retrospective analysis was performed on 240 elderly AIS-LVO patients who underwent SWIM technique in our hospital be-tween February 2019 and February 2024.According to gender,age,occlusion sites and TOAST classifications,they were divided into a modeling group(180 cases)and a verification group(60 cases)in a ratio of 3∶1.Based on the results of modified Rankin scale(mRS)at 3 months after surgery,the patients in the modeling group were further divided into good prognosis subgroup(mRS score:0-2,97 cases)and poor prognosis subgroup(mRS score:3-6,83 cases).Multivari-ate logistic regression analysis was applied to evaluate the relationship between preoperative col-lateral circulation status and prognosis and to identify the influencing factors for prognosis.Then a prediction model for prognosis was constructed,and its performance was evaluated by ROC curve analysis.Results In the modeling group at 3 months of follow-up,the poor prognosis subgroup had significantly larger proportions of posterior circulation occlusion,cardiogenic embolism,ASITN/SIR grades 3-4 and hemorrhage transformation,higher NIHSS score at admission and longer interval from onset to vascular recanalization,while lower ASPECTS score at admission when compared with the good prognosis subgroup(P＜0.01).Multivariate logistic regression analysis showed that occlusion site,TOAST classification,NIHSS score at admission,interval from onset to vascular recanalization and hemorrhage transformation were independent risk fac-tors for poor prognosis,while ASPECTS score at admission and collateral circulation were protec-tive factors of good prognosis in the elderly AIS-LVO patients after SWIM technique(P＜0.01).Hosmer-Lemeshow test showed that the regression equation obtained goodness of fit in the mod-eling group(P=0.435).ROC curve analysis revealed that the AUC,sensitivity and specificity of then constructed prediction model for poor prognosis was 0.855[95％CI(0.797-0.913)],81.93％and 79.38％,respectively.The model was further verified in the data of the verification group(34 cases in good prognosis and 26 cases with poor prognosis),the AUC value,sensitivity and speci-ficity was 0.839[95％CI(0.732-0.947)],84.62％and 79.41％,respectively.Conclusion Our pre-diction model constructed based on screened risk factors for poor prognosis has good validity in patients with AIS-LVO after SWIM technique,which can identify the patients at high risk for poor prognosis.

AIM:This study aims to investigate the effects of aerobic exercise on hypothalamic autophagy and central leptin resistance in obese mice,and to explore the potential mechanisms.METHODS:Forty male C57BL/6J mice,aged 7 to 8 weeks,were randomly assigned to 5 groups:normal control(CON)group,high-fat diet(HFD)group,HFD+exercise(HFD+Exe)group,HFD+phosphate-buffered saline(PBS)group,and HFD+rilmenidine(autophagy ago-nist)group,with 8 mice in each group.Additionally,twelve fibronectin type Ⅲ domain-containing protein 5(Fndc5)gene(encoding irisin precursor protein)knockout(Fndc5 KO)mice were randomly allocated to Fndc5 KO+HFD group and Fndc5 KO+HFD+Exe group,with 6 mice in each group.All mice were fed for 28 weeks.The mice in CON group re-ceived a normal diet,while those in the remaining groups were provided with an HFD.The mice in HFD+Exe and Fndc5 KO+HFD+Exe groups engaged in aerobic treadmill exercise while continuing an HFD from weeks 17 to 28.The mice in HFD+PBS group received intraperitoneal injections of PBS as a control,while those in HFD+rilmenidine group received in-traperitoneal injections of rilmenidine(10 mg?kg-1?d-1),4 times a week over a total duration of 12 weeks(weeks 17 to 28).Following the intervention,serum metabolite levels,as well as concentrations of leptin and irisin,were quantified by ELISA.Morphological alterations in the liver and white adipose tissues were evaluated through oil red O staining and he-matoxylin-eosin(HE)staining.Western blot was utilized to assess the hypothalamic protein levels of autophagy markers,autophagy-related protein 7(ATG7),beclin-1,microtubule-associated protein 1 light chain 3(LC3)and p62,and leptin resistance markers,suppressor of cytokine signaling 3(SOCS3)and protein tyrosine phosphatase 1B(PTP1B).RE-SULTS:Observations of mouse phenotypes indicated that HFD feeding significantly increased body weight,blood lipid content and serum leptin level(P<0.05).The results of HE and oil red O staining demonstrated that HFD feeding marked-ly promoted lipid accumulation in the liver and caused ballooning of white adipocytes.Western blot analyses revealed that HFD feeding significantly down-regulated the protein levels of ATG7,beclin-1 and LC3-Ⅱ/LC3-I,but up-regulated the pro-tein level of p62(P<0.05),thus reducing cellular autophagy capacity.Furthermore,HFD feeding elevated the protein levels of leptin resistance markers SOCS3 and PTP1B(P<0.05).Aerobic exercise and autophagy agonist were found to partially reverse these changes,enhancing cellular autophagy capacity and alleviating leptin resistance.However,these effects were diminished after knockout of Fndc5 gene,further substantiating the role of irisin in exercise-mediated en-hancement of cellular autophagy and attenuation of leptin resistance.CONCLUSION:Aerobic exercise alleviates hypo-thalamic autophagy defect and central leptin resistance in obese mice,which may be associated with exercise-induced irisin.

Objective:To explore the changes of brain excitation/inhibition balance and gray matter volume (GMV) and their correlations with clinical features in benign childhood epilepsy with centrotemporal spikes (BECTS).Methods:A cross-sectional study was performed; 83 BECTS children enrolled from Department of Diagnostic Radiology, Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University from January 2015 to January 2024 were selected as BECTS group. During the same period, 101 age- and gender-matched healthy children were recruited as healthy control group through advertisements in local primary schools. Data of conventional MRI and resting-state functional MRI (rs-fMRI) of the two groups were collected. Whole brain GMV was analyzed by voxel-based morphometry (VBM), and Hurst index was calculated based on time series data of blood oxygen level dependent (BOLD) signal of rs-fMRI. Correlations of GMV and Hurst index with disease duration and onset age in children with BECTS were explored by Pearson correlation analysis.Results:Compared with the healthy control group, the BECTS group had significantly increased GMV and decreased Hurst index in the bilateral Rolandic region ( P<0.05). Pearson correlation analysis showed that in the BECTS group, GMV in bilateral Rolandic region was negatively correlated with onset age ( r=-0.267, P=0.015) and positively correlated with disease course ( r=0.267, P=0.015); Hurst index in bilateral Rolandic region was positively correlated with onset age ( r=0.323, P=0.003) and negatively correlated with disease course ( r=-0.240, P=0.029); Hurst index was negatively correlated with GMV in bilateral Rolandic region ( r=-0.328, P=0.003). Conclusion:BECTS children have excitation/inhibition imbalance in epilepsy-related regions and cortical structural delay, and both of them are related to onset age and disease course.

Objective:To investigate the impact of immunosuppressive therapy on the severity of SARS-CoV-2 infection and cytokine levels in pediatric patients with kidney diseases.Methods:A retrospective analysis was conducted on the clinical data of 40 hospitalized pediatric patients who were diagnosed with SARS-CoV-2 infection at the 900th Hospital of PLA Joint Logistic Support Force from December 2022 to February 2023. Based on their immunosuppressive status prior to SARS-CoV-2 infection, these patients were categorized into immunosuppressive group and non-immunosuppressive group. Independent sample t-tests, Mann-Whitney U tests, and χ2 test were employed to compare the clinical baseline characteristics and laboratory data, the severity of SARS-CoV-2 infection, and the levels of cytokines between the 2 groups. Results:Among the 40 patients, 11 were in the immunosuppressive group (aged 13 (8, 14) years, 9 males and 2 females) and 29 in the non-immunosuppressive group (aged 2 (1, 4) years, 15 males and 14 females). In the immunosuppressive group, 2 were asymptomatic cases, 8 were mild cases, and 1 was moderate case, and there was no severe or critical cases. In the non-immunosuppressive group, 8 were mild cases, 5 were moderate, 15 were severe cases, 1 was critical case, and no asymptomatic cases. The underlying diseases in the immunosuppressive group included nephrotic syndrome (6 cases), IgA vasculitis nephritis (2 cases), lupus nephritis (1 case), post-renal transplantation (1 case), and renal failure (1 case), with a mean total immunosuppression score (TIS) of (3.6±1.4) points. In the non-immunosuppressive group, 2 patients had a history of epilepsy, and the remaining 27 cases had no underlying conditions, all with TIS scores of 0. Compared to the children in the non-immunosuppressive group, those in the immunosuppressive group were more likely to exhibit asymptomatic or mild infection, with lower risks of severe disease, cytokine storm, fever, and cough, but a higher risk of fatigue ( OR=1.22, 2.66, 0.48, 0.12, 0.12, 0.13, 1.22; 95% CI 0.93-1.62, 0.99-7.15, 0.33-0.70, 0.03-0.57, 0.03-0.57, 0.03-0.65, 0.93-1.62; all P<0.05). The levels of cytokine IL-6, interferon-α and interferon-γ in the immunosuppressive group were all lower than those in the non-immunosuppressive group ( Z=2.23, 2.51, 2.92, respectively; all P<0.05). Conclusion:Pediatric patients with kidney diseases receiving appropriate immunosuppressive therapy may mitigate the severity of SARS-CoV-2 infection by suppressing the expression of cytokines.
