ObjectiveThis paper aims to investigate the material basis of the anti-inflammatory efficacy and mechanism of action of Bushen Tongdu prescription （BSTDP）. MethodsThe chemical components of BSTDP and its blood-absorbed components in vivo were systematically identified by using ultra-performance liquid chromatography-linear ion trap-electrostatic field orbitrap high-resolution mass spectrometry （UPLC-LIT-Orbitrap-MS）. Network pharmacology was employed to screen blood-absorbed bioactive components and potential targets of this formula. A protein-protein interaction （PPI） network of core targets was constructed to conduct enrichment analysis. Molecular docking was further utilized to verify the binding affinity between key components and targets. The inflammatory model was established and verified in vivo by using a transgenic zebrafish Tg （mpx： GFP）. At three days post-fertilization （3 dpf）， larvae of zebrafish were randomly assigned to blank group， model group， positive drug dexamethasone acetate group （75 μmol·L^-1）， and BSTDP groups with low， medium， and high doses （500， 1 000， and 2 000 mg·L^-1）. The distribution and quantity of neutrophils in the yolk sac region were observed under a fluorescence microscope. The mRNA expression levels of key genes in the toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear factor kappa-B （NF-κB） signaling pathway and inflammatory factors including interleukin （IL）-1β， IL-6， and tumor necrosis factor-α （TNF-α） were detected by Real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsA total of 120 chemical components were identified in BSTDP， among which 26 original components were confirmed by using serum pharmacochemical methods. A total of 227 common targets linking rheumatoid arthritis （RA） and the blood-absorbed components were screened by network pharmacology. It is suggested that pseudobrucine， vomicine， sinapine， rehmannioside， cinnamyl alcohol glycoside， and methylephedrine exert anti-inflammatory effects by acting on core targets including protein kinase B1 （Akt1）， signal transducer and activator of transcription 3 （STAT3）， tumor necrosis factor （TNF）， TLR4， mitogen-activated protein kinase 14 （MAPK14）， and phosphatidylinositol-4，5-bisphosphate 3-kinase catalytic subunit α （PIK3CA）， thereby modulating multiple signaling pathways such as TLR4 and NF-κB. In vivo verification in zebrafish demonstrates that the maximum tolerable concentration of Bushen Tongdu Formula is 2 000 mg·L^-1. Compared to those in the blank group， zebrafish in the model group showed a significantly higher number of neutrophils in the yolk sac region （P<0.01） and rising mRNA levels of TLR4， MyD88， NF-κB， TNF-α， IL-6， and IL-1β （P<0.01）. Compared to that in the model group， the number of neutrophils was significantly reduced in BSTDP groups with medium and high doses， as well as the dexamethasone acetate group （P<0.05， P<0.01）. There was no statistically significant difference in the low dose group. The mRNA expression levels of TLR4， MyD88， NF-κB， TNF-α， IL-6， and IL-1β were significantly down-regulated （P<0.05， P<0.01）. ConclusionThis paper identifies the material basis of the efficacy of BSTDP， demonstrating that the formula can exert an anti-inflammatory effect through the TLR4/MyD88/NF-κB signaling pathway. The results provide scientific experimental evidence for its further clinical application.

Objective To observe the surgical outcomes and complications of transforaminal endoscopic lumbar discectomy(TELD)and interlaminar endoscopic lumbar discectomy(IELD)in the treatment of lumbar disc herniation(LDH)with prolapse type at the L4/5 segment using full-endoscopic spine surgery.Methods A retrospective analysis was conducted on the clinical data of 75 patients with L4/5 segmental prolapse type LDH who underwent spinal endoscopic surgery from November 2020 to November 2022.Among them,53 patients underwent TELD(TELD group)and 22 patients underwent IELD(IELD group).The surgical outcomes and postoperative therapeutic effect of the two groups were compared.Results Compared with the TELD group,the IELD group had significantly shorter operation time and fewer intraoperative fluoroscopy times,the differences were statistically significant(P<0.05);There were no statistically significant in the length of hospital stay and the incidence of complications between the two groups(P>0.05).All patients were followed up for 12 to 19 months after surgery.The visual analogue scale(VAS)score and Oswestry disability index(ODI)at the last follow-up in both groups were significantly lower than those before surgery,and the IELD group was significantly lower than the TELD group,the differences were statistically significant(P<0.05).Further analysis based on the location of the herniation and nerve roots revealed that,compared with preoperative values,the VAS scores and ODI at the last follow-up were significantly reduced in both groups of patients with shoulder-upper type herniation(10 cases in the TELD group and 6 cases in the IELD group),and the VAS score in the IELD group at the last follow-up was significantly lower than that in the TELD group,the differences were statistically significant(P<0.05).Similarly,both groups of patients with axillary type herniation(8 cases in the TELD group and 16 cases in the IELD group)exhibited significantly reduced VAS score and ODI at the last follow-up than those before operation,with significantly lower in the IELD group compared to the TELD group,the differences were statistically significant(P<0.05).Among the 35 patients with anterior-shoulder type herniation who underwent TELD,the VAS score and ODI at the last follow-up were also significantly lower than those before surgery,the difference was statistically significant(P<0.05).Further analysis based on the Lee classification of herniations revealed that,compared with preoperative values,the VAS score and ODI at the last follow-up were significantly reduced in both groups of patients with herniations in Lee zone Ⅲ(44 cases in the TELD group and 10 cases in the IELD group),and the ODI in the IELD group was significantly lower than that in the TELD group,the differences were statistically significant(P<0.05).Similarly,both groups of patients with LDH in Lee zone Ⅳ(9 cases in the TELD group and 12 cases in the IELD group)exhibited significantly reduced VAS score and ODI at the last follow-up,with significantly lower in the IELD group compared to the TELD group(P<0.05).Conclusion Both TELD and IELD can achieve satisfactory decompression effects in the treatment of LDH with prolapse type at the L4/5 segment.However,IELD offers a relatively shorter operative time,requires fewer X-ray fluoroscopies,and demonstrates superior decompression effects for shoulder-type,axillary-type,Lee Ⅲ and Lee Ⅳ.

Objective To retrospectively study the characteristics and short-term outcomes of patients with decompensated liver cirrhosis accompanied by diastolic cardiac dysfunction,and to inform the clinical diagnosis and treatment of decompensated liver cirrhosis.Methods We retrospectively analyzed the clinical data of patients with liver cirrhosis and diastolic heart dysfunction admitted to Nanfang Hospital of Southern Medical University from April 1,2019 to July 31,2023.The patients were divided into compensated cirrhosis group(n=37)and decompensated cirrhosis group(n=226),and those with decompensated cirrhosis were further divided into subgroups of patients with heart dysfunction(n=84)and patients without heart dysfunction(n=142).We compared two groups using the independent samples t-test and Mann-Whitney U test for continuous data in normal distribution and data in skewed distribution,respectively;compared multiple groups using the Kruskal-Wallis H test,with subsequent paired comparisons using the Wilcoxon test;compared categorical data between two groups using the chi-square test or corrected chi-square test;identified the factors affecting patient survival using a Logistic regression model;and plotted Kaplan-Meier survival curves,with inter-group comparisons using the log-rank test.Results A total of 263 eligible patients were ultimately included,among whom 226 patients were diagnosed with decompensated liver cirrhosis(84 patients with diastolic dysfunction).Between the diastolic dysfunction group and non-diastolic dysfunction group,significant differences were detected in age(t=-4.566,P<0.05),activated partial thromboplastin time(Z=-3.026,P<0.05),prothrombin time(Z=-2.450,P<0.05),international normalized ratio(Z=2.779,P<0.05),and the proportion of moderate esophageal varices(χ2=4.273,P<0.05).During hospitalization,35 patients experienced new or aggravated ascites(18 with cardiac dysfunction and 17 without cardiac dysfunction),6 patients experienced new gastroesophageal variceal bleeding,and 9 patients experienced new or aggravated hepatic encephalopathy(3 with cardiac dysfunction and 6 without cardiac dysfunction).Jaundice was the most common decompensation event upon admission,and electrophysiological abnormalities were the most common electrocardiogram findings upon admission.During the 90-day follow-up period,30 individuals(12 with cardiac dysfunction and 18 without cardia dysfunction)died.The logistic regression analysis showed that age(odds ratio[OR]=1.075,95%confidence interval[CI]:1.033-1.119,P<0.001),N-terminal pro-B-type natriuretic peptide(NT-proBNP,OR=0.996,95%CI:0.992-0.999,P=0.016),and mild/moderate ascites(OR=0.270,95%CI:0.092-0.789,P=0.017)were independent predictive factors for cirrhotic cardiomyopathy.Conclusion Timely attention should be paid to elderly patients with decompensated liver cirrhosis and diastolic heart dysfunction who have a decline in NT-proBNP and mild to moderate ascites.Symptomatic treatment such as diuretics may improve diastolic heart dysfunction.

Objective To evaluate the association of different obesity phenotypes and their components with the risk of cognitive impairment in older Chinese adults,and to assess the association between obesity and cognitive impairment in different cognition-related genetic backgrounds.Methods A cross-sectional study based on the West China Health and Aging Cohort was conducted.Logistic regression was applied to estimate the association of obesity phenotypes and components with cognitive impairment in older Chinese adults stratified by APOE gene and polygenic risk scores.Results A total of 7 316 participants were enrolled,of whom 1 820 had cognitive impairment.Weight gains were associated with a reduced risk of cognitive impairment(odds ratio[OR]=0.96,95%CI,0.95-0.97).Being overweight with a normal waist-to-hip ratio was a protective factor for cognition(OR=0.74,95%CI,0.61-0.90),whereas the coexistence of elevated waist-to-hip ratio and overweight did not increase the risk of cognitive impairment.Sarcopenia was associated with an elevated risk of cognitive impairment.This association was found in both overweight(OR=2.03,95%CI,1.71-2.41)and non-overweight older adults(OR=1.86,95%CI,1.58-2.20),and was significant across all polygenic risk score strata.Conclusion Increasing body mass may serve as a key protective factor against cognitive decline in older adults.Having sarcopenia and obesity is associated with an elevated risk of cognitive impairment,independent of genetic susceptibility.

ObjectiveTo investigate the therapeutic effect of sequential administration of Dihuang Baoyuan granules （DHBY， the prescription for consolidating body resistance） and Fuling Yunhua granules （FLYH， the prescription for treating symptoms） on spontaneous type 2 diabetes mellitus （T2DM） in mice. MethodsAccording to the fasting blood glucose （FBG） level， 12-week-old db/db mice were randomized into six groups： model， DHBY （18.02 g·kg^-1）， FLYH （14.80 g·kg^-1）， sequential administration 1 （SEQ-1， DHBY 18.02 g·kg^-1+FLYH 14.80 g·kg^-1）， sequential administration 2 （SEQ-2， FLYH 14.80 g·kg^-1+DHBY 18.02 g·kg^-1）， and dapagliflozin （Dapa， 1.3 mg·kg^-1）. The m/m mice in the same litter were selected as the normal group. The mice were administrated with corresponding drugs by gavage for 8 consecutive weeks. During the 8 weeks of drug administration and 2 weeks after withdrawal， the retinal thickness， FBG， hemoglobin A1c （HbA1c）， and insulin were determined， and histopathological changes of the pancreas， liver， kidney， and retina were observed by hematoxylin-eosin （HE） staining. ResultsCompared with the model group， SEQ-1 for 4 weeks lowered the FBG level （P<0.05）， raised the insulin level， decreased the triglyceride （TG） level （P<0.05）， increased the number of optic ganglion cells and diminished vacuolar degeneration of pancreatic islet and liver. SEQ-2 lowered FBG and HbA1c levels （P<0.05）， rose the insulin level， increased the retinal thickness and the number of optic ganglion cells （P<0.05）， and alleviated vacuolar degeneration of pancreatic islet and liver. Two weeks after drug withdrawal， Dapa tended to increase FBG and HbA1c compared with those at the time of drug withdrawal. However， the levels of FBG and HbA1c in the SEQ-2 group remained decreasing （P<0.05）. ConclusionSEQ-1 and SEQ-2 can lower the blood glucose level and ameliorate diabetic retinopathy， and SEQ-2 outperformed DHBY and FLYH in lowering the blood glucose level. Moreover， SEQ-2 can maintain the blood glucose-lowering effect after drug withdrawal.
