ObjectiveTo optimize Tusizi prescription for ovarian reserve function based on the uniform design method combined with in vitro experiments and explore the underlying mechanisms of this prescription. MethodsThe uniform design method was adopted to design a 5-factor 11-level experiment on the water extract of Tusizi prescription. The cell-counting kit-8 (CCK-8) assay was employed to measure the viability of human ovarian granulosa cells (KGN cells) treated with Tusizi prescription extracts 1-11, and multivariate regression analysis was performed to determine the optimal herb ratio in this prescription. The potential targets of active ingredients in the prescription were retrieved from traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP) and encyclopedia of traditional Chinese medicine (ETCM). The common targets shared by Tusizi prescription and diminished ovarian reserve (DOR) were selected and imported into search tool for the retrieval of interacting genes/proteins (STRING) to construct a protein-protein interaction (PPI) network and into gene function annotation database (DAVID) for gene ontology (GO) analysis. The CCK-8 assay was used to measure the viability of ovarian germline stem cells treated with hyperoside. The CCK-8 assay, 5-ethynyl-2'-deoxyuridine (EdU) staining, terminal-deoxynucleoitidyl transferase mediated nick-end labeling (TUNEL), and enzyme-linked immunosorbent assay (ELISA) were employed to examine the proliferation, apoptosis, and estradiol (E2) secretion of KGN cells treated with the water extract 11 of Tusizi prescription (Cuscutae Semen-Lycii Fructus-Dioscoreae Rhizoma-Poria-Nelumbinis Semen 4∶4∶2∶1∶1) and the optimal prescription screened by uniform design. On this basis, the optimal prescription composition for maximizing the effect on ovarian reserve function was determined and preliminary insights into the underlying mechanisms of this prescription were gained. ResultsA total of 147 common targets were obtained from 278 targets of Tusizi prescription and 1 721 targets of DOR. GO analysis revealed 194 biological processes, primarily involving cellular responses to exogenous compound stimuli, negative regulation of apoptotic process, and positive regulation of cell proliferation. It identified 84 cellular components, including cell membrane, mitochondria, and neuronal cell body, as well as 144 molecular functions such as enzyme binding, estrogen response element binding, and nuclear estrogen receptor binding. The multivariate regression analysis revealed that when Tusizi prescription was composed of Cuscutae Semen, Lycii Fructus, Dioscoreae Rhizoma, Poria, and Nelumbinis Semen in a ratio of 27∶30∶17∶12∶14, the water extract of Tusizi prescription had the best effect of enhancing the viability of KGN cells. CCK-8 results showed that compared with the normal group, the hyperoside group demonstrated increased viability of ovarian germline stem cells (P<0.01). The CCK-8, EdU, and ELISA results showed that compared with the normal group, the optimal prescription screened by uniform design and the water extract 11 of Tusizi prescription increased the proliferation and reduced the apoptosis of KGN cells (P<0.05, P<0.01). ELISA results showed that compared with the normal group, the water extract 11 of Tusizi prescription promoted the E2 secretion of KGN cells (P<0.05), while the optimal prescription screened by uniform design had no significant effect on the E2 secretion. ConclusionBoth the water extract 11 of Tusizi prescription (Cuscutae Semen-Lycii Fructus-Dioscoreae Rhizoma-Poria-Nelumbinis Semen 4∶4∶2∶1∶1) and the optimal prescription screened by uniform design (Cuscutae Semen-Lycii Fructus-Dioscoreae Rhizoma-Poria-Nelumbinis Semen 27∶30∶17∶12∶14) can improve the ovarian reserve function, and the former has better effect. Tusizi prescription can modulate biological processes (such as cell proliferation and apoptosis) and molecular functions (such as enzyme binding and estrogen response element binding) through active components like hyperoside to promote the proliferation and E2 secretion and inhibit the apoptosis of KGN cells, thereby protecting the ovarian reserve function.

Objective :
To investigate the antidepressant effects and the underlying mechanisms of tetrahydrocurcumin(THC) and its nanoparticle formulation(THCN).
Methods :
Forty-six male ICR mice were randomly divided into Con group, LPS group, THC group, THCN group and SER group. A mouse depression model was established by intraperitoneal administration of LPS. The anxiety and depression-like behaviors of mice were evaluated by open field test(OFT) and forced swimming test(FST). Myelin staining was applied to assess the extent of demyelination in the prefrontal cortex of the mice. The prefrontal cortex and hippocampus were further examined for the expression levels of glial fibrillary acidic protein(GFAP) and Toll-like receptor 4(TLR4) through quantitative immunofluorescence assays.
Results :
Compared with the Con group, the LPS group showed increased anxiety-like and depressive-like behaviors in both the long-term and short-term experiments(P<0.05); the degree of demyelination increased in the LPS group of the long-term experiment(P<0.01); the expression of GFAP was reduced in the LPS group of the short-term experiment(P<0.01), while the expression of TLR4 increased(P<0.05); the expression of TLR4 decreased in the THC group(P<0.01); the expression of GFAP in the prefrontal cortex of the THCN group was reduced(P<0.01), while the expression of TLR4 increased(P<0.05). Compared with the LPS group, the THC group showed reduced depressive-like behaviors in the long-term experiment(P<0.05), while the anxiety-like and depressive-like behaviors of the THCN group and the SER group were reduced(P<0.05), and the anxiety-like and depressive-like behaviors of the THC group and the THCN group were reduced in the short-term experiment(P<0.05); the degree of demyelination was reduced in the THC group, THCN group and SER group in the long-term experiment(P<0.05); the expression of GFAP increased in the THC group of the short-term experiment(P<0.05), while the expression of TLR4 was reduced(P<0.05), and the expression of GFAP increased in the THCN group(P<0.05). Compared with the THC group, the THCN group and the SER group showed reduced anxiety-like behaviors in the long-term experiment(P<0.05); the expression of GFAP in the prefrontal cortex of the THCN group was reduced in the short-term experiment(P<0.05), while the expression of TLR4 in the hippocampal DG area increased in the short-term experiment(P<0.01).
Conclusion
Tetrahydrocurcumin and its nanoparticle formulation both exert significant ameliorative effects on depression-like behaviors and demyelination in mice induced by lipopolysaccharide. The antidepressant mechanism of THC appears to be mediated through the down-regulation of TLR4 and the up-regulation of GFAP. The mechanism underlying the antidepressant action of THCN seems predominantly focused on the enhancement of GFAP expression.

ObjectiveTo explore the mechanism of Shaoyaotang in the prevention and treatment of colitis-associated carcinogenesis (CAC) based on myeloid-derived suppressor cells (MDSCs)-related immunosuppressive microenvironment. MethodsA total of 140 six-week-old SPF FVB male mice were randomly divided into seven groups: Blank group, Shaoyaotang without model group (7.12 g·kg-1), model group, sulfasalazine group (0.52 g·kg-1), Shaoyaotang low-dose group (3.56 g·kg-1), Shaoyaotang medium-dose group (7.12 g·kg-1) and Shaoyaotang high-dose group (14.24 g·kg-1), with 20 mice in each group. The blank control group and the Shaoyaotang without model group received a single intraperitoneal injection of physiological saline (10 mg·kg-1), while the other five groups were given a single intraperitoneal injection of azoxymethane (AOM) (10 mg·kg-1). After 1 week, the mice were given drinking water containing 2% dextran sulfate sodium (DSS) for 1 week, followed by normal drinking water for 2 weeks. This cycle was repeated three times over a total period of 14 weeks to establish the CAC mouse model. Each group was administered gavage once daily for 2 weeks starting on the 14th day of the experiment, followed by three times a week until the end of the experiment. The body weight of the mice was recorded weekly. Mice were sacrificed on the 28th and 98th days of the experiment. After dissection, the colon length, colon weight, spleen weight, tumor size, and tumor number were measured. Hematoxylin and eosin (HE) staining was used to assess the pathological morphology of colon tumor tissue. Flow cytometry was used to detect MDSCs, regulatory T cells (Tregs), CD4+ T cells, CD8+ T cells, and the CD4+/CD8+ T cell ratio in the spleen. Immunohistochemistry was used to detect the expression levels of programmed cell death protein-1 (PD-1), programmed cell death ligand 1 (PD-L1), phosphorylated AMP-activated protein kinase (p-AMPK), phosphorylated nuclear factor-κB (p-NF-κB), and hypoxia-inducible factor 1α (HIF-1α) in the colon tissue. ResultsOn day 14, compared with the blank group, the body weight of the model group was significantly reduced (P<0.01), reaching its lowest point on day 28 (23.39 ± 0.95 ) g. On days 28 and 98, compared with the blank group, the colon length in the model group was significantly shortened (P<0.01), the colon index significantly increased (P<0.01), the spleen index significantly increased (P<0.01), and the tumor load significantly increased (P<0.01). HE staining showed that in the model group, tumor cells, a large number of inflammatory cell infiltrates, goblet cell disappearance, and crypt loss were observed. In each dose group of Shaoyaotang, the damage to the colonic mucosa, inflammatory cell infiltration, and crypt structure destruction were alleviated. Compared with the model group, the body weight of mice in each dose group of Shaoyaotang increased. On day 98, the colon length was significantly increased (P<0.01), the colon index significantly decreased (P<0.01), the spleen index significantly decreased (P<0.01), and the tumor burden significantly decreased (P<0.01) in each Shaoyaotang dose group. On days 28 and 98, MDSCs and Tregs in the spleen of the medium- and high-dose Shaoyaotang groups were significantly reduced (P<0.01), while CD4+ T cells and the CD4+/CD8+ T cell ratio were significantly increased (P<0.01). The proportion of CD8+ T cells in the spleen and the expression levels of PD-1 and PD-L1 in the colon tissues of mice in each Shaoyaotang dose group were significantly increased to varying degrees (P<0.05, P<0.01). On days 28 and 98, the expression of p-AMPK-positive cells in the colon tissue of the medium- and high-dose Shaoyaotang groups was significantly increased (P<0.01), while the expression of p-NF-κB and HIF-1α was significantly reduced (P<0.01). ConclusionShaoyaotang can regulate MDSC recruitment and modulate the immune function of T lymphocyte subsets to inhibit the occurrence and development of AOM/DSS-induced CAC in mice. The mechanism may be related to the activation of the AMPK/NF-κB/HIF-1α pathway.

ObjectiveTo explore the target of Erzhiwan in reducing myocardial injury in ovariectomized mice through non-targeted myocardial metabolomics combined with experimental verification. MethodsOvariectomized mouse model was selected, 40 female C57BL/6 mice were randomly divided into sham operation group, model group, estrogen group(estradiol valerate, 1.3×10-4 g·kg-1), Erzhiwan low and high dose groups(3.12, 9.36 g·kg-1), with 8 mice in each group. Each administration group was given the corresponding dose of Erzhiwan by gavage, and the sham operation group and model group were given equal volume of distilled water by gavage for 12 weeks. Echocardiography was used to detect cardiac function, hematoxylin-eosin(HE) staining was used to observe myocardial morphological changes, and enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of estrogen, N-terminal pro-brain natriuretic peptide(NT-proBNP), hypersensitive troponin T(hs-TnT), total cholesterol(TC), triglyceride(TG), low density lipoprotein cholesterol(LDL-C), high density lipoprotein cholesterol(HDL-C), interleukin(IL)-1β, IL-18 and tumor necrosis factor-α(TNF-α). The non-targeted metabolomics of mouse myocardium were analyzed by ultra performance liquid chromatography-quadrupole-electrostatic field orbital trap high-resolution mass spectrometry(UPLC-Q-Exactive Orbitrap MS), and the differential metabolites and corresponding metabolic pathways were obtained. The mRNA expression levels of phosphatidylinositol 3-kinase(PI3K) and protein kinase B(Akt) in mouse myocardial tissues were detected by real-time fluorescence quantitative polymerase chain reaction(Real-time PCR), and the protein expression levels of PI3K, Akt, phosphorylated(p)-Akt were detected by Western blot. ResultsCompared with the sham operation group, the model group showed abnormal cardiac function, increased myocardial fiber space, cardiomyocyte atrophy, sarcoplasmic aggregation, and occasional dissolution or rupture of muscle fiber, the level of estrogen in the serum was decreased, the levels of NT-proBNP, hs-TnT, IL-1β, IL-18, TNF-α, TG, TC and LDL-C were increased, and the level of HDL-C was decreased(P<0.01). Compared with the model group, Erzhiwan could increase the level of estrogen, improve the abnormal cardiac function, reduce the pathological injury of myocardial tissue, decrease the levels of myocardial injury markers(NT-proBNP, hs-TnT) and inflammatory factors(IL-1β, IL-18, TNF-α), decrease the levels of TG, TC, LDL-C, and increased the level of HDL-C(P<0.01). The results of non-targeted myocardial metabolomics showed that 31 of the 162 differential metabolites between the model group and sham operation group were significantly adjusted after administration of Erzhiwan, which were mainly glycerol phospholipid metabolites. Pathway enrichment results showed that Erzhiwan mainly affected glycerophospholipid metabolic pathway, PI3K-Akt pathway, cyclic guanosine monophosphate(cGMP)-protein kinase G(PKG) pathway and other metabolic pathways. Compared with the sham operation group, the levels of phosphatidylcholine(PC, 11 types) and phosphatidylethanolamine(PE, 5 types) in mouse myocardial tissue of the model group were increased(P<0.05, P<0.01), and the mRNA and protein expressions of PI3K and p-Akt were decreased(P<0.05, P<0.01). Compared with the model group, the levels of PC(11 types) and PE(5 types) were decreased(P<0.05, P<0.01) in myocardial tissue of Erzhiwan group, the mRNA and protein expressions of PI3K and p-Akt were elevated(P<0.01). ConclusionErzhiwan can alleviate the pathological injury of myocardium in ovariectomized mice, improve the abnormal cardiac function, improve lipid metabolism disorder, and reduce the levels of myocardial injury markers and inflammatory factors, which involves a number of signaling and metabolic pathways in the heart, among which glycerophospholipid metabolism pathway and PI3K/Akt pathway may have key roles.

Atopic dermatitis (AD) is a common pruritic and chronic inflammatory dermatosis in clinical practice and is one of the diseases responding specifically to traditional Chinese medicine (TCM). With the launch of biological agents and small molecule drugs and the development and implementation of guidelines of diagnosis and treatment, clinical pathways of treatment of moderate to severe AD, and consensus on the whole-process management of AD, the clinical efficacy of moderate to severe AD has been significantly improved. However, there are still many unmet clinical needs that require more effective methods to meet. In response to the Opinions of the CPC Central Committee and the State Council on Facilitating the Inheritance, Innovation, and Development of Traditional Chinese Medicine and the spirit of the National Conference on TCM, the China Association of Chinese Medicine organized more than 20 experts in TCM dermatology, Western medicine dermatology, interdisciplinary fields, and industries to discuss the difficulties and advantages of TCM in the treatment of AD. TCM treatment for AD can not only improve rash and relieve itching but also solve many concomitant syndromes. The abundant external treatment methods of TCM have advantages for different special populations and rash characteristics. The concept of treating disease before its onset in TCM is in line with the chronic disease management mode of prevention and treatment of atopic march and prevention of recurrence. In addition, TCM therapy can reduce the use of topical glucocorticoids and has good safety. Regarding the comorbidity of AD, equal emphasis on TCM and Western medicine and multidisciplinary joint treatment should be advocated to achieve maximum benefit for patients. The exchange of TCM and Western medicine has clarified the positioning and advantages of TCM intervention in AD, providing guidance for clinical and scientific research.

ObjectiveTo establish a model that can quickly identify the aroma components in different parts of Nardostachys jatamansi, so as to provide a quality control basis for the market circulation and clinical use of N. jatamansi. MethodsHeadspace solid-phase microextraction-gas chromatography-mass spectrometry(HS-SPME-GC-MS) combined with Smart aroma database and National Institute of Standards and Technology(NIST) database were used to characterize the aroma components in different parts of N. jatamansi, and the aroma components were quantified according to relative response factor(RRF) and three internal standards, and the markers of aroma differences in different parts of N. jatamansi were identified by orthogonal partial least squares-discriminant analysis(OPLS-DA) and cluster thermal analysis based on variable importance in the projection(VIP) value >1 and P<0.01. The odor data of different parts of N. jatamansi were collected by Heracles Ⅱ Neo ultra-fast gas phase electronic nose, and the correlation between compound types of aroma components collected by the ultra-fast gas phase electronic nose and the detection results of HS-SPME-GC-MS was investigated by drawing odor fingerprints and odor response radargrams. Chromatographic peak information with distinguishing ability≥0.700 and peak area≥200 was selected as sensor data, and the rapid identification model of different parts of N. jatamansi was established by principal component analysis(PCA), discriminant factor alysis(DFA), soft independent modeling of class analogies(SIMCA) and statistical quality control analysis(SQCA). ResultsThe HS-SPME-GC-MS results showed that there were 28 common components in the underground and aboveground parts of N. jatamansi, of which 22 could be quantified and 12 significantly different components were screened out. Among these 12 components, the contents of five components(ethyl isovalerate, 2-pentylfuran, benzyl alcohol, nonanal and glacial acetic acid,) in the aboveground part of N. jatamansi were significantly higher than those in the underground part(P<0.01), the contents of β-ionone, patchouli alcohol, α-caryophyllene, linalyl butyrate, valencene, 1,8-cineole and p-cymene in the underground part of N. jatamansi were significantly higher than those in the aboveground part(P<0.01). Heracles Ⅱ Neo electronic nose results showed that the PCA discrimination index of the underground and aboveground parts of N. jatamansi was 82, and the contribution rates of the principal component factors were 99.94% and 99.89% when 2 and 3 principal components were extracted, respectively. The contribution rate of the discriminant factor 1 of the DFA model constructed on the basis of PCA was 100%, the validation score of the SIMCA model for discrimination of the two parts was 99, and SQCA could clearly distinguish different parts of N. jatamansi. ConclusionHS-SPME-GC-MS can clarify the differential markers of underground and aboveground parts of N. jatamansi. The four analytical models provided by Heracles Ⅱ Neo electronic nose(PCA, DFA, SIMCA and SQCA) can realize the rapid identification of different parts of N. jatamansi. Combining the two results, it is speculated that terpenes and carboxylic acids may be the main factors contributing to the difference in aroma between the underground and aboveground parts of N. jatamansi.

ObjectiveBased on literature data mining, this study explores the modeling elements of diarrhea-predominant irritable bowel syndrome (IBS-D) animal models in China and abroad, providing references and suggestions for improving modeling methods and evaluation indicators. MethodsRelevant literature on IBS-D animal experiments from 2014 to 2024 was retrieved through computer searches in databases such as China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP, Chinese Medical Journals Full-text Database, and PubMed. Information on experimental animal species, gender, body weight, modeling methods, modeling periods, intervention controls, modeling standards, and detection indicators was organized. Microsoft Excel 2021 software was used to establish a database and perform statistical analysis to examine the characteristics of IBS-D animal models. ResultsA total of 398 articles that met the inclusion criteria were reviewed. The IBS-D animal models were predominantly established using SD rats, Wistar rats, and C57BL/6 mice. Male animals were more commonly used, with rats typically aged 6-8 weeks and mice aged 4-6 weeks. In terms of interventions, piverium bromide was the main Western medicine, Tongxieyaofang was the primary Chinese medicine, and electroacupuncture was the primary acupuncture method. Among the modeling methods, the multi-factor combined composite modeling approach was the most common. Modeling periods were mainly concentrated between 1-14 days and 15-30 days. The success criteria for modeling were mainly evaluated based on the animal's general condition, fecal appearance, visceral sensitivity, gastrointestinal motility, behavior, and pathology. Detection indicators included apparent indexes, pathological markers, biochemical indicators, oxidative stress, brain-gut peptides, neurotransmitters, inflammatory factors, immune function, intestinal permeability, autophagy, apoptosis, proteins related to relevant signaling pathways, intestinal microbiota and its metabolites, etc. ConclusionThere are various methods for establishing IBS-D animal models, but no unified and universally accepted method has been established. The operation of the same modeling methods and the evaluation standards of the models vary across studies. Based on the results of data mining, the authors suggest that the multi-factor combined composite modeling approach most closely reflects the pathophysiological processes of IBS-D, better simulating the complex clinical symptoms of IBS-D patients, such as abdominal pain and diarrhea, and has a high degree of clinical relevance. This method is relatively recommended. While animal models in general align with Western medicine standards, models incorporating traditional Chinese medicine (TCM) syndromes are relatively few. Therefore, one of the future directions for research is to establish IBS-D animal models that meet the combined clinical disease and syndrome requirements of both Western and Chinese medicine.
