		                        			OBJECTIVE To predict and validate the potential mechanisms of Kaixinsan (KXS) in ameliorating neuroinflammation in Alzheimer’s disease (AD). METHODS Network pharmacology was employed to identify core anti- inflammatory components and key inflammatory targets of KXS for AD. Gene ontology (GO) functional annotation, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment, and molecular docking were performed. Based on these findings, male SD rats were used to establish an AD model via chronic D-galactose induction. The effects of KXS on AD rats were evaluated, including quantitative behavioral score, learning and memory parameters (escape latency, platform crossings, platform quadrant distance and time), organ indexes (heart, liver, spleen, thymus), histopathological alterations in the hippocampus, and expressions of inflammation-related pathway proteins and their upstream/downstream regulators. RESULTS Core anti-inflammatory components of KXS for AD included gomisin B, panaxytriol, gomisin A, enhydrin, vulgarin and panaxydol, while key inflammatory targets involved nuclear factor-kappa B subunit 1( NFKB1), nuclear factor-κB p65( NF-κB p65), interleukin-1β( IL- 1β), IL-6, Toll-like receptor 4 (TLR4), tumor necrosis factor, nucleotide-binding domain leucine-rich repeat and pyrin domain- containing receptor 3 (NLRP3) and caspase-1 (CASP1). GO and KEGG pathway enrichment involved inflammatory response, phosphorylation and the NF-κB signaling pathway. Molecular docking confirmed strong binding affinities between core components and key targets. Animal experiments demonstrated that, compared to the model group, KXS significantly alleviated histopathological damage (e.g., neuronal shrinkage, reduced Nissl bodies in hippocampal CA1, CA3, and DG regions), increased organ indexes (except for liver index) and Nissl-stained positive cells, improved learning and memory performance, and reduced behavioral scores (at the 8 and 12 weeks of the experiment) and protein expression of NF- κB p65, phosphorylated NF- κB p65, TLR4, NLRP3, CASP1 and IL-1β. CONCLUSIONS KXS effectively mitigates neuroinflammation, reduces hippocampal neuronal injury, and enhances learning and memory ability in AD rats, potentially through suppressing the NF-κB signaling pathway and its upstream/ downstream regulators.

		                        			ObjectiveTo explore the effect of different drying conditions on the appearance and intrinsic quality indicators of Pinelliae Rhizoma for screening suitable drying conditions, so as to provide reference for its standardized production and quality evaluation. MethodsDifferent dried samples of Pinelliae Rhizoma were prepared by lime-assisted sweating method and intermittent drying method. Visual analysis was employed to measure the color brightness values(L*) of the surface, cross-section and powder of the samples, texture analyzer was used to determine the hardness of the samples under different drying conditions. The total starch content was calculated by measuring the contents of amylose and amylopectin in the samples with ultraviolet-visible spectroscopy. High performance liquid chromatography(HPLC) was used to determine the contents of seven nucleoside components(uracil, hypoxanthine, uridine, inosine, guanosine, β-thymidine and adenosine) in the samples. Pearson correlation analysis was conducted to explore the correlation between the external characteristics and intrinsic indicators of the different dried samples. Principal component analysis(PCA) was used to comprehensively rank the data of various indicators, and partial least squares-discriminant analysis(PLS-DA) was used to screen differential components with variable importance in the projection(VIP) value>1. Furthermore, the difference between the optimal drying condition for Pinelliae Rhizoma and the traditional sun-drying method was explored by independent samples t-test. ResultsWith the increase of temperature, the color of the intermittently dried samples gradually deepened, while their hardness gradually decreased. Concurrently, the contents of extract, total starch, uridine and adenosine exhibited an upward trend, whereas the contents of uracil, hypoxanthine and inosine displayed a downward trajectory. Compared with the intermittent drying group, the content of extract in the samples subjected to lime-assisted sweating increased. With the increase of lime dose, the hardness and the total content of nucleoside components in the samples showed a downward trend, while the total starch content showed an upward trend. Correlation analysis showed that the comprehensive score of L* was negatively correlated with the contents of uracil, hypoxanthine and inosine, and positively correlated with the contents of uridine, guanosine and adenosine. Hardness was negatively correlated with adenosine content, and positively correlated with the contents of inosine, uracil and hypoxanthine. Through comprehensive consideration and comprehensive score of principal components, the method of 5% lime-mixed sweating for 6 days emerged as the top-ranking approach. Except for the extract, the results of independent samples t-test showed that there was no significant difference between the 5% lime-mixed sweating for 6 days and the traditional sun-drying in terms of other content indicators. ConclusionThe whiteness and firmness of Pinelliae Rhizoma exhibit significant correlations with its chemical composition, while uridine, uracil, guanosine, adenosine and inosine are the key constituents responsible for the quality difference of Pinelliae Rhizoma under different drying conditions. The lime-assisted sweating method optimized in this study can be proposed as a viable alternative to the traditional sun-drying method. This method not only ensures the quality of the medicinal material but also effectively reduces the drying time and prevents mold contamination, which provides a valuable reference for the standardization of drying conditions and the establishment of quality evaluation criteria for Pinelliae Rhizoma.

		                        			ObjectiveTo investigate the mechanism of action of Huangqi Guizhi Wuwutang (HGWT) against cerebral ischemia-reperfusion injury (CIRI) based on bioinformatics and experimental validation. MethodsBiological informatics methods were used to screen for active components of HGWT and their targets. The GEO database was utilized to obtain CIRI-related differentially expressed genes (DEGs), and platforms such as GeneCards were used to identify disease targets. Venn diagram analysis was conducted to identify overlapping targets, followed by protein-protein interaction (PPI), gene ontology (GO), and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis, as well as immune infiltration and immune cell differential analysis. Core genes (Hub genes) were screened using LASSO regression and ROC curves, and molecular docking was used to validate the binding efficiency between the active components of the drug and the core targets. A rat CIRI model was established, with rats randomly divided into five groups (n=10): Sham surgery group (Sham), model group (MG), and low-dose (LD,5.3 g·kg-1), medium-dose (MD,10.6 g·kg-1), and high-dose (HD,21.2 g·kg-1) HGWT groups. From 3 days before modeling to 7 days after surgery, oral administration was performed daily: Sham and MG groups received physiological saline, while each drug group received the corresponding dose of HGWT. Hematoxylin-eosin (HE) staining, Nissl staining, and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL staining) were used to assess the repair effects of HGWT on neural damage. Western blot analysis was used to detect B-cell lymphoma-2 protein (Bcl-2), Bcl-2-associated X protein (Bax), signal transducer and activator of transcription 3 (STAT3), phosphorylated STAT3 [p-STAT3 (Tyr705)], protein kinase B1 (Akt1), and phosphorylated Akt1 [p-Akt1 (Ser473)], among other target proteins. ResultsAfter screening, 56 common target points of DEGs-disease-drug were obtained. GO and KEGG analyses indicated that HGWT primarily functions in pathways such as apoptosis, oxidative stress, and inflammatory responses. Immune infiltration analysis revealed a significant association between HGWT's anti-CIRI activity and immune cells such as Th17 cells and myeloid-derived suppressor cells (MDSCs) (P0.01). LASSO-ROC analysis identified Akt1, Caspase-3, glycogen synthase kinase-3β (GSK-3β), and STAT3 as core genes. Molecular docking confirmed that Hub genes exhibit significant binding affinity with the active components of HGWT (binding energy ≤ -5 kJ·mol-1)(1 cal≈4.186 J). Animal experiment results showed that compared with the sham group, the MG group exhibited significant neuronal necrosis, nuclear condensation, and vacuolar degeneration in rat brains, with a significant decrease in Nissl body density (P0.01) and increased neuronal apoptosis in rat brains as indicated by TUNEL staining (P0.01). Compared with the MG, the LD, MD, and HD groups showed reduced neuronal necrosis, nuclear condensation, and vacuolar degeneration in rat brain neurons, increased Nissl body density, and reduced apoptosis (P0.01), with significant differences among the drug groups (P0.01). Western blot results showed that compared with the sham group, the MG group had reduced Bcl-2 and p-Akt1 (P0.01) and increased Bax and p-STAT3 (P0.01). Compared with the MG group, the drug groups showed increased Bcl-2 and p-Akt1 (P0.01) and decreased Bax and p-STAT3 (P0.01). There were no significant changes in total Akt1 and STAT3 protein levels among the groups. ConclusionBased on network pharmacology and experimental verification, HGWT may exert its neuroprotective effects by regulating the phosphorylation levels of Akt1 and STAT3, thereby alleviating cell apoptosis, inflammatory responses, and oxidative stress in rat brain tissue following CIRI. This provides theoretical support for the clinical treatment of CIRI.

MethodsUltra performance liquid chromatography-quadrupole/electrostatic field orbitrap high resolution mass spectrometry(UPLC-Q-Exactive Orbitrap-MS) metabolomics was used to identify the metabolites in no sweating group(F1), sweating 2 d group(F2) and sweating 4 d group(F3), the differences of metabolites between the groups were compared by principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA), and differential metabolites were screened according to the variable importance in the projection(VIP) value>1 and P<0.05, and the pathway enrichment of the differential metabolites was analyzed by Kyoto Encyclopedia of Genes and Genomes(KEGG). ResultsThe results of PCA and OPLS-DA showed a clear distinction between the three groups of samples, indicating significant differences in the compositions of the three groups of samples. A total of 433 differential metabolites were screened between the F1 and F2, with 154 up-regulated and 279 down-regulated, the significant up-regulated metabolites were tangeritin, 5-O-demethylnobiletin and so on, while the metabolites with significant down-regulation included alternariol, fortunellin, etc. A total of 379 differential metabolites were screened between the F2 and F3, with 150 up-regulated and 229 down-regulated, the significant up-regulated metabolites were isoimperatorin, helianyl octanoate and so on, and the significant down-regulated metabolites were hovenoside I, goyasaponin Ⅲ, etc. KEGG pathway enrichment analysis showed that tyrosine metabolism, isoquinoline alkaloid biosynthesis, phenylalanine, tyrosine and tryptophan biosynthesis, tryptophan metabolism, valine, leucine and isoleucine biosynthesis, pantothenate and coenzyme A biosynthesis may be the key pathways affecting metabolite differences of B. balsamifera after sweating treatment. ConclusionSweating can reduce the content of endophytic mycotoxins in B. balsamifera and has a great impact on the synthesis and metabolic pathways of total flavonoids and auxin. This study can provide a reference for the process research on the sweating conditions of B. balsamifera.

		                        			ObjectiveTo explore the therapeutic effects and mechanisms of modified Danggui Shaoyaosan on acne based on the c-Jun N-terminal kinase (JNK)/p38 mitogen-activated protein kinase (p38 MAPK) pathway. MethodsA rat ear acne model was established in SD rats, and the rats were divided into a blank group, a model group, and low-, medium-, and high-dose groups of modified Danggui Shaoyaosan (7.15, 14.30, 28.60 g·kg·d-1), with six rats in each group. After the administration for 14 consecutive days, morphological changes in the rats' auricles were observed, and hematoxylin-eosin (HE) staining was used to examine the pathological changes in the acne-affected ear tissue. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the levels of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in the ear tissue. Quantitative reverse transcription polymerase chain reaction (Real-time PCR) was performed to detect the mRNA expression levels of Caspase-3, B cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), JNK, and p38 MAPK in the ear tissue. Additionally, Western blot analysis was conducted to assess the protein levels of Caspase-3, Bcl-2, Bax, JNK, and p38 MAPK in the ear tissue. The active components and key targets of modified Danggui Shaoyaosan in the treatment of acne were identified through network pharmacology analysis. Molecular docking was then employed to evaluate the interactions between the main active components and the key targets. ResultsThe results of the animal experiment demonstrated that compared with those in the blank group, rats in the model group exhibited redness, swelling, thickening, hardening, dryness, and roughness of the auricle. The surface showed sebaceous scales and desquamation, accompanied by acne-like lesions such as papule-like elevations or cysts. Histopathological changes included keratinization, epidermal thickening, dermal collagen fiber degeneration and necrosis, subcutaneous muscle degeneration and necrosis, inflammatory cell infiltration, and fibrous tissue proliferation. The mRNA and protein expression levels of IL-1β, TNF-α, Caspase-3, Bax, JNK, and p38 MAPK were significantly increased (P<0.01), while those of Bcl-2 were significantly decreased (P<0.01). In comparison to the model group, the modified Danggui Shaoyaosan groups showed marked improvement in acne-like lesions of the auricle, with varying degrees of histopathological damage reduction. Additionally, the mRNA and protein expression levels of IL-1β, TNF-α, Caspase-3, Bax, JNK, and p38 MAPK in the tissue were significantly decreased (P<0.05, P<0.01), while those of Bcl-2 were significantly increased (P<0.05, P<0.01). Network pharmacology analysis indicated that the key compounds in modified Danggui Shaoyaosan responsible for its effects in treating acne may include acacetin, kaempferol, luteolin, quercetin, wogonin, and baicalein. These compounds exerted their effects by modulating core targets such as TNF, IL-1β, Caspase-3, and Bcl-2, thereby alleviating inflammation and apoptosis and ultimately improving acne symptoms. ConclusionModified Danggui Shaoyaosan may exert its therapeutic effects on acne by inhibiting the activation of the JNK/p38 MAPK pathway, thereby alleviating inflammation and apoptosis. 
		                        		
		                        		
		                        		
		                        	
7.Regulation of Signaling Pathways Related to Diabetes Mellitus-induced Erectile Dysfunction by Traditional Chinese Medicine: A Review

		                        			Erectile dysfunction (ED) is one of the most common manifestations of male reproductive system damage, and it is also a common complication of diabetes mellitus (DM). ED is closely related to the patient’s quality of life, sexual partner relationship, and family stability. In addition, it is an early warning signal for many physical diseases. As the incidence of DM keeps growing, the incidence of diabetes mellitus-induced erectile dysfunction (DMED) increases accordingly. Currently, drug treatment for ED presents limited effects, and the treatment of DMED is more difficult. Therefore, developing effective and safe drugs is a clinical problem that needs to be solved urgently. Recent studies have proved that traditional Chinese medicine (TCM) can alleviate oxidative stress, reduce inflammation, and modulate autophagy by regulating multiple signaling pathways, thus ameliorating DMED, showing definite therapeutic effects via multiple pathways, targets, and links. Multiple signaling pathways such as phosphatidylinositol-3-kinase/protein kinase B (PI3K/Akt), nitric oxide (NO)-cyclic guanosine monophosphate (cGMP), Ras homolog family member A (RhoA)/Rho, nuclear factor erythroid 2-related factor 2 (NRF2), mitogen-activated protein kinase (MAPK), adenosine monophosphate-activated protein kinase (AMPK), and protein kinase C (PKC) mediate the occurrence and development of DMED, while there is still a lack of conclusive records. By reviewing relevant articles published in recent years, this paper summarizes the role of the above-mentioned signaling pathways in the occurrence and development of DMED and the research progress in TCM treatment of DMED via regulation of related signaling pathways. This review is expected to provide new ideas and references for further clinical diagnosis and treatment, basic research, and drug development.

		                        			ObjectiveTo investigate the effect of laminin subunit α3 (LAMA3) on the epithelial-mesenchymal transition (EMT), invasion, and metastasis abilities of pancreatic cancer (PC). MethodsA comprehensive analysis was performed for tumor- and EMT-related databases to identify the EMT genes associated with PC, especially LAMA3. The methods of qRT-PCR and Western blot were used to measure the expression level of LAMA3 in PC tissue and cell lines; immunofluorescence assay was used to determine the localization of LAMA3 in PANC-1 cells; Transwell assay was used to investigate the effect of LAMA3 on the invasion and migration abilities of PC cells. The t-test was used for comparison of continuous data between groups. ResultsThe analysis of the TCGA database identified 3 EMT-related oncogenes for PC, i.e., LAMA3, AREG, and SDC1. The LASSO-Cox regression model showed that LAMA3 had the most significant impact on the prognosis of PC (risk score=0.256 1×LAMA3+0.043 1×SDC1+0.071 4×AREG). The Cox model and nomogram showed that the high expression of LAMA3 was an independent risk factor for the poor prognosis of PC (hazard ratio=1.32, 95% confidence interval: 1.07 — 1.62, P<0.01). Experimental results showed that there was a significant increase in the expression of LAMA3 in pancreatic cancer tissue compared with the normal pancreatic tissue. Compared with the HPDE cell line, there were varying degrees of increase in the expression of LAMA3 in pancreatic cancer AsPC-1, BxPC-3, PANC-1, MIA PaCa-2, and SW1990 cell lines, with the highest expression level in PANC-1 cells. The enrichment analysis showed that LAMA3 was associated with the biological processes and signaling pathways such as EMT, collagen metabolism, extracellular matrix degradation, the TGF-β pathway, and the PI3K pathway. After the knockdown of LAMA3, there were significant reductions in the expression levels of N-Cadherin, Vimentin, and Snail, while there was a significant increase in the expression level of E-Cadherin. Transwell assay showed that there were significant reductions in the invasion and migration abilities of PANC-1 cells after the knockdown of LAMA3. ConclusionLAMA3 is highly expressed in PC and can promote the EMT, invasion, and migration of PC cells, and therefore, LAMA3 may be used as a novel diagnostic marker and a new therapeutic target for PC.

		                        			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 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.
