OBJECTIVE To investigate the correlation of component content with colorimetric values during the roasting process of Ziziphus jujuba , and to provide criteria for discriminating the roasting degree of Z. jujuba . METHODS Samples were prepared by dry stir-frying for different roasting times. The eight main components in raw Z. jujuba and the samples stir-fried for different roasting times-namely adenosine, magnoflorine, jujuboside A, spinosin, 6-feruloylspinosin, betulinic acid, oleic acid, and linoleic acid-were quantitativel y analyzed using ultra-performance liquid chromatography. The chromaticity values were determined using a UV spectrophotometer. The correlation and differences between the chromaticity values of Z. jujuba at different roasting times and their components content were analyzed by Pearson correlation analysis, linear regression analysis, principal component analysis (PCA) , cluster heatmap analysis (CHA), and partial least squares discriminant analysis (PLS-DA) to clarify the processing endpoint. RESULTS As the roasting time increased, the contents of linoleic acid and oleic acid decreased, while the contents of other components exhibited an increasing trend. Concurrently, the colorimetric value L* and E*ab were observed to decline, whereas the a* value demonstrated a gradual increase. Pearson correlation analysis revealed that L* and E*ab exhibited a significant negative correlation with the contents of adenosine, spinosin, 6-feruloylspinosin, jujuboside A, betulinic acid and magnoflorine ( P <0.05). The results of linear regression analysis indicate that the content of six components, including adenosine, in the medicinal material can be preliminarily predicted by analyzing the colorimetric values of Z. jujuba powder. PCA and CHA successfully classified raw and stir-fried samples. The PLS-DA results indicated that L*, E*ab, a*, linoleic acid content, and oleic acid content were the main parameters that differentiated the color and quality of Z. jujuba at different roasting times. After frying for 9 to 10 minutes, the colorimetric values L* and E*ab decreased to their minimum values and stabilized, while a* remained consistently high with little variation;simultaneously, the concentrations of the six major components, excluding linoleic acid and oleic acid, reached their peak levels. CONCLUSIONS A significant correlation between the colorimetric values of Z. jujuba and the contents of six components, including adenosine, is confirmed. The optimal roasting time range is determined to be 9-10 minutes. Furthermore, the colorimetric value-component content correlation analysis method established in this study proved to be practical and applicable for discriminating the roasting degree of Z. jujuba .

Stroke is the leading cause of death and disability among adults in China, and its common complications include digestive system abnormalities, cognitive impairment, depression, stroke-associated pneumonia, and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang (XLCQT) is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically, XLCQT is often used to treat stroke and its complications. However, the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally, since the basic research is weak, the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis, medicinal properties, safety evaluation, and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients, resveratrol, kaempferol, luteolin, chrysoeriol, apigenin, (+)-catechin, and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex, including inflammatory response, brain-gut axis, hypothalamic-pituitary-adrenal (HPA) axis, intestinal flora, neurotrophic factors, autophagy, oxidative stress, and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

Objectives:
. This study aimed to investigate the regulatory functions of gamma-aminobutyric acid (GABA)ergic neural circuits from the inferior colliculus (IC) to the medial geniculate body (MGB) in salicylate-induced tinnitus.
Methods:
. Mice were treated with salicylate to induce tinnitus, and tinnitus-like behaviors were evaluated via gap prepulse inhibition of acoustic startle. Using combined viral tracing methodologies, we identified and mapped the pathways and connections from the IC to the MGB. Furthermore, we employed Gq-coupled human M3 designer receptors exclusively activated by designer drugs (DREADDs) and Gi-coupled human M4 DREADDs to achieve targeted excitation or suppression of GABAergic neurons in the IC and MGB. Following the administration of clozapine N-oxide, which binds to these receptors, we modulated these neural circuits to assess their impact on tinnitus severity in a mouse model.
Results:
. Our findings demonstrated that mice exposed to salicylate exhibited tinnitus-like behaviors. GABAergic neurons projecting retrogradely from the MGB to the IC were primarily concentrated in the external nucleus of the IC. After clozapine N-oxide administration, chemogenetic activation of IC-MGB GABAergic neurons aggravated salicylate-induced tinnitus. Additionally, activation of GABAergic neurons between the IC and MGB induced the perception of tinnitus even without salicylate. However, chemogenetic inhibition of the IC-MGB GABAergic circuit did not reverse salicylate-induced tinnitus.
Conclusion
. These findings suggest that activation of the IC-MGB GABAergic neural circuit may contribute to tinnitus generation through a mechanism distinct from that of salicylate-induced tinnitus. This study provides novel insights into the mechanisms underlying tinnitus.

ObjectiveTo investigate the risk factors for postpancreatectomy acute pancreatitis (PPAP) after minimally invasive pancreaticoduodenectomy (MIPD) and their association with major complications, to improve the understanding of PPAP and postoperative pancreatic fistula (POPF), and to reduce the incidence rates of PPAP and POPF. MethodsA retrospective analysis was performed for the clinical data of 114 patients who underwent MIPD in Department of Hepatobiliary and Pancreatic Surgery, The First Affiliated Hospital of University of South China, from March 2015 to December 2023, and the definition of PPAP and its diagnostic criteria provided by the International Study Group of Pancreatic Surgery were used to determine the presence or absence of PPAP. The independent samples t-test or the Mann-Whitney U rank sum test was used for comparison of continuous data between groups, and the Kruskal-Wallis H test was used for comparison between multiple groups, and the Dunn-test was used for further comparison between two groups.; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups., and the Bonferroni-test was used for further comparison between two groups. The multivariate logistic regression analysis was used to identify the risk factors for PPAP after MIPD. ResultsOf all 114 patients undergoing MIPD, 27 (23.7%) experienced PPAP. The multivariate analysis showed that main pancreatic duct diameter ≤3 mm (odds ratio [OR]=5.083, 95% confidence interval [CI]: 1.703 — 15.172, P=0.004), soft pancreatic texture (OR=5.925, 95%CI: 1.986 — 17.677, P=0.001), and C-reactive protein ≥180 mg/L on day 1 after surgery (OR=5.419, 95%CI: 1.586 — 18.513, P=0.007) were independent risk factors for the onset of PPAP after MIPD. Clinical analyses showed that the patients with PPAP tended to have significantly higher incidence rates of POPF, peritoneal infection, Clavien-Dindo grade 3/4 complications, discharge with tube, and 90-day postoperative death (χ2=5.676, 5.460, 9.863, 5.439, and 4.207, all P<0.05). ConclusionMain pancreatic duct diameter, pancreatic texture, and C-reactive protein on day 1 after surgery are closely associated with the onset of PPAP after MIPD, and PPAP can lead to other postoperative complications and even death.

OBJECTIVE To explore the pharmacokinetic characteristics of 3 blood-absorbed components of Xiangshao sanjie oral liquid in rats with hyperplasia of mammary gland (HMG). METHODS Female SD rats were divided into control group and HMG group according to body weight, with 6 rats in each group. The HMG group was given estrogen+progesterone to construct HMG model. After modeling, two groups were given 1.485 g/kg of Xiangshao sanjie oral liquid (calculated by crude drug) intragastrically, once a day, for 7 consecutive days. Blood samples were collected before the first administration (0 h), and at 5, 15, 30 minutes and 1, 2, 4, 8, 12, 24 hours after the last administration, respectively. Using chlorzoxazone as the internal standard, the plasma concentrations of ferulic acid, paeoniflorin and rosmarinic acid in rats were detected by UPLC-Q/TOF-MS. The pharmacokinetic parameters [area under the drug time curve (AUC0-24 h, AUC0-∞), mean residence time (MRT0-∞), half-life (t1/2), peak time (tmax), peak concentration (cmax)] were calculated by the non-atrioventricular model using Phoenix WinNonlin 8.1 software. RESULTS Compared with the control group, the AUC0-24 h, AUC0-∞ and cmax of ferulic acid in the HMG group were significantly increased (P<0.05); the AUC0-24 h, AUC0-∞ , MRT0-∞ , t1/2 and cmax of paeoniflorin increased, but there was no significant difference between 2 groups (P>0.05); the AUC0-24 h and MRT0-∞ of rosmarinic acid were significantly increased or prolonged (P<0.05). C ONCLUSIONS In HMG model rats, the exposure of ferulic acid, paeoniflorin and rosmarinic acid in Xiangshao sanjie oral liquid all increase, and the retention time of rosmarinic acid is significantly prolonged.

ObjectiveStudies have shown that nuciferine has anti-cerebral ischemia effect, but the specific mechanism of action has not been elaborated. Based on the transcriptome results, the pharmacological mechanism of nuciferine against cerebral ischemia was analyzed from multiple dimensions including tissue, cell, pathological process, biological process and signaling pathway. MethodsThirty SD rats were randomly divided into the sham group, model group and nuciferine group(40 mg·kg-1) according to weight. Except for the sham group, the model of middle cerebral artery occlusion(MCAO) was established by thread embolization method after 30 min of administration in the other two groups. Twenty-four hours after surgery, transcriptome sequencing was used to detect the gene expression profiles in the cortex penumbra of rat cerebral tissue, and gene ontology(GO) and kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment analysis were performed for differentially expressed genes. The mechanismof nuciferine against cerebral ischemia was analyzed from 5 dimensions of tissue, cell, pathological process, biological process and signaling pathway by the transcriptome-based multi-scale network pharmacology platform(TMNP). ResultsTranscriptome sequencing and gene quantitative analysis showed that 667 genes were significantly reversed by nuciferine. Further enrichment analysis of KEGG and GO suggested that the pathways of nuciferine involved regulating stress response, ion transport, cell proliferation and differentiation, and synaptic function. TMNP research found that at the tissue level, nuciferine could significantly improve the cerebral tissue injury caused by ischemia. At the cellular and pathological levels, nuciferine could play an anti-cerebral ischemia role by improving the state of various nerve cells, mobilizing immune cells, regulating inflammation. And at the level of biological processes and signaling pathways, nuciferine mainly acted on the processes such as vascular remodeling, inflammation-related signaling pathways, and synaptic signaling. ConclusionCombined with the results of transcriptome sequencing, gene quantitative analysis and TMNP, the mechanism of nuciferine against cerebral ischemia may be related to processes such as intervening in stress response and inflammation, affecting vascular remodeling and regulating synaptic function. These results can provide a basis and reference for further study of the pharmacological mechanism of nuciferine against cerebral ischemia.

Electromagnetic fields can regulate the fundamental biological processes involved in bone remodeling. As a non-invasive physical therapy, electromagnetic fields with specific parameters have demonstrated therapeutic effects on bone remodeling diseases, such as fractures and osteoporosis. Electromagnetic fields can be generated by the movement of charged particles or induced by varying currents. Based on whether the strength and direction of the electric field change over time, electromagnetic fields can be classified into static and time-varying fields. The treatment of bone remodeling diseases with static magnetic fields primarily focuses on fractures, often using magnetic splints to immobilize the fracture site while studying the effects of static magnetic fields on bone healing. However, there has been relatively little research on the prevention and treatment of osteoporosis using static magnetic fields. Pulsed electromagnetic fields, a type of time-varying field, have been widely used in clinical studies for treating fractures, osteoporosis, and non-union. However, current clinical applications are limited to low-frequency, and research on the relationship between frequency and biological effects remains insufficient. We believe that different types of electromagnetic fields acting on bone can induce various “secondary physical quantities”, such as magnetism, force, electricity, acoustics, and thermal energy, which can stimulate bone cells either individually or simultaneously. Bone cells possess specific electromagnetic properties, and in a static magnetic field, the presence of a magnetic field gradient can exert a certain magnetism on the bone tissue, leading to observable effects. In a time-varying magnetic field, the charged particles within the bone experience varying Lorentz forces, causing vibrations and generating acoustic effects. Additionally, as the frequency of the time-varying field increases, induced currents or potentials can be generated within the bone, leading to electrical effects. When the frequency and power exceed a certain threshold, electromagnetic energy can be converted into thermal energy, producing thermal effects. In summary, external electromagnetic fields with different characteristics can generate multiple physical quantities within biological tissues, such as magnetic, electric, mechanical, acoustic, and thermal effects. These physical quantities may also interact and couple with each other, stimulating the biological tissues in a combined or composite manner, thereby producing biological effects. This understanding is key to elucidating the electromagnetic mechanisms of how electromagnetic fields influence biological tissues. In the study of electromagnetic fields for bone remodeling diseases, attention should be paid to the biological effects of bone remodeling under different electromagnetic wave characteristics. This includes exploring innovative electromagnetic source technologies applicable to bone remodeling, identifying safe and effective electromagnetic field parameters, and combining basic research with technological invention to develop scientifically grounded, advanced key technologies for innovative electromagnetic treatment devices targeting bone remodeling diseases. In conclusion, electromagnetic fields and multiple physical factors have the potential to prevent and treat bone remodeling diseases, and have significant application prospects.
