ObjectiveTo explore effect of Xianlian Jiedu prescription on the recurrence of colorectal cancer （CRC） and investigate the related mechanisms. MethodsA postoperative recurrence model was established in 25 Balb/c mice by injecting CT26 cells subcutaneously into the armpit， followed by surgical removal of 99% of the subcutaneous tumor. The mice were randomly divided into model group， low-dose Xianlian Jiedu prescription （XLJDP-L） group （6.45 g·kg^-1·d^-1）， medium-dose Xianlian Jiedu prescription （XLJDP-M） group （12.9 g·kg^-1·d^-1）， high-dose Xianlian Jiedu prescription （XLJDP-H） group （25.8 g·kg^-1·d^-1）， and 5-fluorouracil （5-FU） group （1×10^-3 g·kg^-1·d^-1）. The mice were euthanized after 14 days of continuous intervention， and recurrent tumor tissue was harvested. Hematoxylin and eosin （HE） staining was used to observe pathological and morphological changes in the recurrent tumor tissue. Immunohistochemistry （IHC） was employed to assess the expression of proliferating cell nuclear antigen （Ki67）， vascular endothelial growth factor （VEGF）， and platelet-endothelial cell adhesion molecule （CD31） in recurrent tumor tissue. The Western blot was used to detect the protein expression levels of angiopoietin-2 （ANG-2）， VEGF， phosphorylated-protein kinase B （p-Akt）， protein kinase B （Akt）， phosphorylated-phosphatidylinositol 3-kinase （p-PI3K）， and phosphatidylinositol 3-kinase （PI3K） in recurrent tumor tissue. ResultsBefore treatment， there were no statistical differences in tumor volume， tumor weight， and body mass among the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group compared to the model group， indicating model stability. After treatment， compared with those in the model group， the tumor volume and tumor weight in the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group were significantly reduced （P<0.01）， showing dose dependency. Meanwhile， there were no significant differences in body weight among the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group compared to the model group. HE staining showed that compared with that in the model group， tumor tissue in the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group had loosely arranged cells， increased intercellular spaces， small and shriveled nuclei， light staining， fewer mitotic figures and atypical nuclei， and increased necrotic areas. IHC showed that compared with those of the model group， the positive rates of Ki67， VEGF， and CD31 in the recurrent tumor tissue of the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group were significantly reduced （P<0.01） in a dose-dependent manner. Western blot results showed that compared with those of the model group， the protein expression levels of ANG-2 and VEGF in the recurrent tumor tissue of the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group were significantly downregulated （P<0.05， P<0.01）， and the p-Akt/Akt and p-PI3K/PI3K ratios were significantly decreased in a dose-dependent manner （P<0.05， P<0.01）. ConclusionXianlian Jiedu prescription significantly inhibits the recurrence of CRC in mice after subcutaneous tumor surgery. The mechanism may involve regulating the PI3K/Akt pathway and downregulating key angiogenic proteins such as ANG-2， VEGF， and CD31.

Objective Exploring the mechanism of"Wushen acupuncture"in alleviating chronic fatigue in rats from the perspective of mitophagy.Methods Forty male Wistar rats were randomly allocated into a normal group and a modeling group,where the latter employed a protocol combining exhaustive swimming with tail-clamping stimuli to induce a rat model of chronic fatigue.Post-modeling,the normal group was subdivided randomly into a blank group and a presumed control group with specifics requiring clarification.Meanwhile,the modeling group was further randomized into a model group,a"Wushen acupuncture"group that underwent acupuncture at the Baihui and Sishencong points,and a non-acupoint control group,in which acupuncture was applied to 5 mm behind houshencong which is non-meridian,non-acupoint sites on the rats' heads and necks.The modeling and treatment outcomes in rats are assessed via the tail suspension test.Protein relative expression levels of adenosine 5'-monophosphate-activated protein kinase(AMPK),mammalian target of rapamycin(mTOR),and peroxisome proliferator-activated receptor γ coactivator 1-alpha(PGC-1α)in rat skeletal muscle were detected using Western blot.Meanwhile,the relative mRNA expression levels of PTEN induced putative kinase 1(PINK1)and Parkin were measured by Real-Time PCR.Results In contrast to the baseline cohort,rats in the induced fatigue model displayed a reduction in struggles,struggle duration,swaying frequency,and swaying duration(P<0.05).When juxtaposed against the fatigue-induced model group,the"Wushen acupuncture"intervention cohort manifested a substantial increase in these behavioral parameters(P<0.05).Furthermore,relative to the"Wushen acupuncture"intervention group,the non-acupoint control cohort showed a decrease in struggles,struggle duration,swaying frequency,and swaying duration(P<0.05).Versus the baseline group,the fatigue-induced model cohort demonstrated a marked decrease in the relative expression levels of AMPK,PGC-1α,PINK1,and Parkin mRNA in skeletal muscle tissue(P<0.05),alongside an increase in mTOR protein expression(P<0.05).Compared to the fatigue-induced model group,the"Wushen acupuncture"intervention led to an increase in the relative expression levels of AMPK,PGC-1α,PINK1,and Parkin mRNA(P<0.05),and a decrease in mTOR protein expression(P<0.05).When juxtaposed against the"Wushen acupuncture"intervention group,the non-acupoint control cohort showed decreased relative expression levels of AMPK,PGC-1α,PINK1,and Parkin mRNA(P<0.05),and increased mTOR protein expression(P<0.05).Conclusion The"Wushen acupuncture"have been shown to enhance the alleviation of chronic fatigue symptoms in rat models and modulate the functionality of mitochondrial autophagy.This therapeutic effect is believed to be mechanistically linked to the regulation of both the PINK1/Parkin pathway and the AMPK/mTOR signaling cascade.

The reversal rates of chronic inflammation at the corpus lesser curvature and corpus greater curvature (5.2%, 12/231 vs. 0, 0/123; 4.7%, 8/170 vs. 0, 0/88), the reversal rates of atrophy at the antrum lesser curvature, antrum greater curvature, corpus lesser curvature, and the corpus greater curvature (6.8%, 22/323 vs. 1.3%, 2/151; 9.2%, 29/315 vs. 1.4%, 2/144; 14.2%, 38/267 vs. 2.5%, 3/121; 20.8%, 35/168 vs. 5.8%, 4/69), and the reversal rates of intestinal metaplasia at the antrum lesser curvature, antrum greater curvature, gastric angle, and the corpus lesser curvature (29.8%, 39/131 vs. 9.1%, 4/44; 41.0%, 32/78 vs. 12.5%, 3/24; 33.3%, 44/132 vs. 4.8%, 3/63; 50.0%, 37/74 vs. 8.7%, 2/23) of the LTEVB 12C group were all higher than those of the placebo group, and the differences were statistically significant ( χ2=6.58, 5.12, 5.60, 8.61, 11.43, 6.59, 7.30, 4.95, 15.92, 7.62; all P<0.05). There were no statistically significant differences in the effective rates and reversal rates of active inflammation at different locations between the LTEVB 12C group and the placebo group (all P>0.05). The results of logistic regression analysis (taking the antrum lesser curvature as the reference) further confirmed that the reversal rates of chronic inflammation ( OR=0.22, 95% confidence interval (95% CI): 0.07 to 0.67; OR=0.24, 95% CI: 0.07 to 0.80), atrophy ( OR=0.28, 95% CI: 0.16 to 0.49; OR=0.28, 95% CI: 0.16 to 0.49), and intestinal metaplasia ( OR=0.42, 95% CI: 0.24 to 0.77; OR=0.20, 95% CI: 0.08 to 0.52) at the corpus lesser curvature and corpus greater curvature were all higher than those at the antrum lesser curvature, and the differences were statistically significant (all P<0.05). There were no statistically siginificant differences in the reversal rates of the aforementioned pathological features between the antrum greater curvature, gastric angle, and the antrum lesser curvature (all P>0.05). Conclusion:LTEVB 12C can achieve good efficacy in the treatment of CAG, and the chronic inflammation, atrophy, and intestinal metaplasia at multiple locations are improved, especially at the corpus lesser curvature and the corpus greater curvature.

OBJECTIVE To identify the chemical components of Shenbai Jiedu Decoction(SBJDD),a traditional Chinese medi-cine(TCM)prescription clinically used for the treatment of colorectal adenoma(CRA),and explore the potential mechanism of SBJDD preventing and treating CRA carcinogenesis.METHODS An ultra-high performance liquid chromatography-time of flight-mass spectrometry(UPLC-Q-TOF-MS)method was established to detect the chemical components in the decoction of SBJDD and the plas-ma samples of rats after administration with SBJDD.Based on the network pharmacological method,SBJDD was screened for the poten-tial active ingredients at different stages of CRA carcinogenesis,and the mechanism of the anti-cancer effect of SBJDD was explored.In vitro experiments were also carried out to verify the mechanism of anti-colorectal cancer(CRC)action of SBJDD.RE-SULTS The detection data of UPLC-Q-TOF-MS showed that 152 components were found from SBJDD water extraction.41 chemical compounds were identified in plasma samples from rats administrated with SBJDD.Network pharmacology analysis indicated that during the CREI stage,the potential active ingredients in SBJDD,including epiberberine,and kushenol H,might affect target proteins such as PIK3CA,MAPK3 and PIK3CB.This,in turn,can influence signaling pathways like PI3K-AKT and Ras signaling pathways,and regulate biological processes like protein phosphorylation,and signal transduction.During the CRA stage,the potential active ingredi-ents from SBJDD,such as 3,7-dihydroxycoumarin,palmatine,and kushenol A,might affect target proteins such as AKT and EGFR.This can regulate the negative regulation of apoptotic process,and positive regulation of cell proliferation,and modify HIF-1,and Rap1 signaling pathways.During the progression of CRA carcinogenesis,potential active ingredients such as 3,7-dihydroxycouma-rin may interact with TP53,and impact the PI3K-AKT,and Thyroid hormone signaling pathways to regulate biological processes,in-cluding positive regulation of transcription from RNA polymerase Ⅱ promoter,and negative regulation of apoptotic process.In the CRC stage,core ingredients like p-coumaric acid may bind with proteins such as PRKCB.This binding may impact the signaling pathways that negatively affect EGFR tyrosine kinase inhibitor resistance,and PI3K-AKT signaling pathways.Additionally,it may regulate bio-logical processes,including negative regulation of apoptotic process,signal transduction,and protein phosphorylation.In vitro experi-ment results indicated that SBJDD inhibited the proliferation of HT29 cells and suppressed the expression of EGFR and PKC proteins.CONCLUSION The UPLC-Q-TOF-MS method is established to effectively separate the chemical constituents in SBJDD,which are mainly composed of alkaloids,organic acids and flavonoids components.Components from SBJDD dock with different targets during the carcinogenesis process of CRA and regulate cancer-related signaling pathways to exert therapeutic effects.
