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.

ObjectiveTo explore the biological foundation of colorectal adenoma in damp-heat accumulation syndrome and the possible anti-tumor mechanism of Shenbai Jiedu prescription. MethodEight patients with colorectal adenoma in damp-heat accumulation syndrome， 11 patients with non-damp-heat accumulation syndrome， and 10 patients with colorectal cancer recruited by Jiangsu Provincial Hospital of Traditional Chinese Medicine from February 2019 to December 2020 meeting the inclusion criteria were clinically obtained， and the tissue of the three groups of patients was subjected to transcriptome sequencing to screen for the differentially expressed genes between the syndrome and the diseases. The intersection of the differentially expressed genes between the syndrome and the disease was taken for further screening of the differentially expressed genes sequentially increasing or sequentially decreasing in patients with non-damp-heat accumulation syndrome， damp-heat accumulation syndrome， and colorectal cancer， and functional enrichment analysis and signaling pathway enrichment analysis were carried out. Real-time polymerase chain reaction （Real-time PCR） was used to detect the effect of Shenbai Jiedu prescription on the expression of the above key differential genes. ResultBy comparing the damp-heat accumulation syndrome and non-damp-heat accumulation syndrome， a total of 384 differentially expressed genes were screened， of which 203 were up-regulated genes， and 181 were down-regulated genes. By comparing the colorectal adenoma of colorectal cancer and damp-heat accumulation syndrome， a total of 2 965 differentially expressed genes were screened， of which 2 460 were up-regulated genes， and 505 were down-regulated genes. The intersection of differentially expressed genes of the two groups was taken， and a total of 58 differentially expressed genes with the same changes were screened. The gene ontology functions were mainly enriched in UDP-galactose： β-N-acetylglucosamine beta-1，3-galactosyltransferase activity， N-acetyllactosaminide beta-1，3-N-acetylglucosaminyltransferase activity， and poly-N-acetyllactosamine biosynthetic process. Kyoto Encyclopedia of Genes and Genomes （KEGG） signaling pathways were mainly enriched in glycosphingolipid biosynthesis-globo and isoglobo series， glycosphingolipid biosynthesis-lacto and neolacto series， and IL-17 signaling pathway. Shenbai Jiedu prescription significantly inhibited the expression of key genes involved in the enrichment， such as FOSB and B3GALT5， in a dose-dependent manner （P<0.05）. ConclusionGlycolipid metabolism may be the biological foundation of colorectal adenoma in damp-heat accumulation syndrome， and Shenbai Jiedu prescription may inhibit colorectal adenoma carcinogenesis by down-regulating the expression of FOSB and B3GALT5.

ObjectiveTo observe the effects of Shenbai Jiedu prescription on fecal metabolomics and intestinal flora diversity distribution in patients with colorectal adenoma and explore its potential targets. MethodA total of 21 patients diagnosed with colorectal adenoma were enrolled in this study. Following a four-week administration of Shenbai Jiedu prescription， their clinical symptoms were observed， and fecal samples of patients before and after treatment were collected. Untargeted metabolomics and metagenomic analysis based on liquid chromatography-mass spectrometry （LC-MS） were employed to investigate the possible metabolic pathway of Shenbai Jiedu prescription and its influence on the distribution of intestinal flora in patients. ResultThe total scores of traditional Chinese medicine （TCM） syndromes of patients after drug administration decreased significantly （P<0.01）. The results of untargeted metabolomics showed that the distribution of metabolites exhibited aggregation before and after drug administration， and a total of 106 differential metabolites were screened out （P<0.05）. The Kyoto encyclopedia of genes and genomes （KEGG） enrichment analysis revealed that arginine-proline metabolism， ferroptosis， glycine， and serine and threonine metabolism were significantly enriched metabolic pathways （P<0.05）. Notably， L-4-hydroxyglutamate semialdehyde， glutathione， isopentenyl pyrophosphate， creatinine， 4-acetamido-2-aminobutanoic acid， and guanidoacetic acid were found to be involved in these aforementioned metabolic pathways. Furthermore， the association between these metabolites and different intestinal flora was analyzed， and the results showed that Shenbai Jiedu prescription could interfere with metabolic pathways such as amino acid and ferroptosis in patients with colorectal adenoma by regulating intestinal flora such as Lachnoclostridium， Eggerthella， and Dialister （P<0.05）. ConclusionShenbai Jiedu prescription may improve the clinical symptoms of patients by increasing the abundance of intestinal beneficial bacteria， reducing the abundance of harmful bacteria， and regulating metabolic pathways such as amino acid and ferroptosis in patients with colorectal adenoma. This study may provide some research ideas and directions for Shenbai Jiedu prescription to interfere with colorectal adenoma recurrence and carcinogenesis.

Colorectal adenoma is a benign tumor originating from the mucosal glandular epithelium of the colorectum and belongs to the category of intraepithelial neoplasia. Its etiology and pathogenesis are not completely clear， and some patients have genetic factors. In recent years， with the improvement in living standards， the incidence of colorectal adenoma has gradually increased due to high-fat diets， intestinal flora disorder， and emotional disturbance. As one of the precancerous lesions of colorectal cancer， colorectal adenoma is increasingly threatening human health. Surgical resection is the most direct and effective method for the treatment of colorectal adenoma， but some patients with colorectal adenoma have the possibility of recurrence after resection. At present， there is still a lack of effective prevention and treatment measures for the recurrence of colorectal adenoma. Traditional Chinese medicine （TCM） plays a unique advantage in improving the clinical symptoms of patients with colorectal adenoma and preventing postoperative recurrence and carcinogenesis. Therefore， this review summarized the clinical research and mechanism of TCM compounds in the prevention and treatment of colorectal adenoma in recent years. The clinical study on the prevention and treatment of colorectal adenoma by TCM compounds can be divided into internal treatment， external treatment， and internal and external combined treatment. The internal treatment mainly focuses on strengthening the spleen， and the external treatment includes retention enema， acupoint application， and other methods. The internal and external combined treatment is mainly based on the internal administration of TCM compounds combined with acupuncture， retention enema， and acupoint stimulation. The study on the mechanism of TCM compounds in preventing and treating colorectal adenoma was mainly explored from the aspects of regulating intestinal flora， regulating cell proliferation immune function， and achieving anti-inflammation. This review summarized the research progress of TCM compounds in the prevention and treatment of colorectal adenoma in recent years and provided a reference for future treatment with TCM.

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.

Objective:This study aimed to explore the clinical value of myostatin(MST) and follistatin(FST) as biological biomarkers in evaluating sarcopenia in elderly women.Methods:This was a retrospective cross-sectional study that enrolled 350 females aged 20-89 years who underwent physical examinations in Shanghai Huadong Hospital in 2021. Demographic characteristics, muscle mass, fat mass, bone mineral density, hand grip strength, gait speed, and serum indices of MST and FST were collected.Results:The serum levels of MST did not change significantly with age. However, the serum levels of FST increased with age. In women aged≥60 years, MST was positively correlated with total lean mass and appendicular skeletal muscle index(ASMI; r=0.236, P=0.041; r=0.289, P=0.014), while FST was negatively correlated with ASMI( r=-0.265, P=0.030). In multivariate stepwise regression analysis, after adjusting for age, body mass index, hip bone mineral density, and total fat mass, only FST was independently correlated with ASMI( β=-0.238, P=0.006), while MST was not correlated with ASMI. The receiver operating characteristic curve was plotted using muscle mass reduction as the state variable and serum FST level as the test variable. The area under the curve was 0.753. And when the FST cutoff value was 17.49 ng/mL, the maximum Jordan index was 0.46, with a sensitivity of 77.3% and a specificity of 68.7%. Women aged ≥60 years were divided into three groups based on serum FST levels. Compared to the upper third of the serum FST level group, the low third of the FST level group had a significantly reduced risk of suffering from sarcopenia( OR=0.098, P =0.036). Conclusions:Serum FST lever has a better correlation with muscle mass among elderly women, making it a promising biomarker for evaluating muscle mass.

Objectives: . We aimed to develop a new calculation model for calcium requirements in dialysis patients following parathyroidectomy. Methods: . A total of 98 patients with secondary hyperparathyroidism receiving parathyroidectomy from January 2014 to January 2022 were enrolled in this study. Among these patients, 78 were randomly selected for construction of the calcium requirement calculation model, and the remaining 20 patients were selected for model validation. The calcium requirement model estimated the total calcium supplementation for 1 week after surgery using variables with significant relationships in the derivation group by stepwise multiple linear regression analysis. Bias, precision, and accuracy were measured in the validation group to determine the performance of the model. Results: . The model was as follows: calcium requirement for 1 week after surgery=33.798–8.929×immediate postoperative calcium+0.190×C-reactive protein–0.125×age+0.002×preoperative intact parathyroid hormone+0.003×preoperative alkaline phosphatase (R2=0.8). The model was successfully validated. Conclusion . We generated a novel model to guide calcium supplementation. This model can assist in stabilizing the serum calcium levels of patients during the early postoperative period. Furthermore, it contributes to the individualized and precise treatment of hypocalcemia in patients following parathyroidectomy.

Purpose: This study aimed to identify prognostic factors for patients with distant lymph node-involved gastric cancer (GC) using a machine learning algorithm, a method that offers considerable advantages and new prospects for high-dimensional biomedical data exploration. Materials and Methods: This study employed 79 features of clinical pathology, laboratory tests, and therapeutic details from 289 GC patients whose distant lymphadenopathy was presented as the first episode of recurrence or metastasis. Outcomes were measured as anycause death events and survival months after distant lymph node metastasis. A prediction model was built based on possible outcome predictors using a random survival forest algorithm and confirmed by 5×5 nested cross-validation. The effects of single variables were interpreted using partial dependence plots. A contour plot was used to visually represent survival prediction based on 2 predictive features. Results: The median survival time of patients with GC with distant nodal metastasis was 9.2 months. The optimal model incorporated the prealbumin level and the prothrombin time (PT), and yielded a prediction error of 0.353. The inclusion of other variables resulted in poorer model performance. Patients with higher serum prealbumin levels or shorter PTs had a significantly better prognosis. The predicted one-year survival rate was stratified and illustrated as a contour plot based on the combined effect the prealbumin level and the PT. Conclusions Machine learning is useful for identifying the important determinants of cancer survival using high-dimensional datasets. The prealbumin level and the PT on distant lymph node metastasis are the 2 most crucial factors in predicting the subsequent survival time of advanced GC.Trial Registration: ChiCTR Identifier: ChiCTR1800019978

Objective:To explore the risk factors of hypocalcemia and the correlation between calcium supplementation and clinical parameters after parathyroidectomy (PTX) in maintenance hemodialysis patients with secondary hyperparathyroidism (SHPT), and to analyze the effect of calcium supplementation after PTX on the long-term prognosis of patients.Methods:This study was a single-center retrospective study. The patients who underwent PTX in maintenance hemodialysis patients with SHPT in the Huashan Hospital affiliated to Fudan University from October 2014 to March 2021 were retrospectively enrolled. Total PTX with auto transplantation or total PTX alone were the surgical procedures. According to the postoperative requirement of calcium in the first week, the patients were divided into two groups: high calcium supplement (>16.05 g/week) group and low calcium supplement group (≤16.05 g/week). According to the average serum calcium level in the first week after operation, the patients were divided into hypocalcemia group (≤2.1 mmol/L) and non-hypocalcemia group (>2.1 mmol/L) and the differences of clinical parameters between the two groups were compared. The correlation between clinical parameters and the postoperative calcium requirement was examined through Pearson or Spearman correlation analysis. The influencing factors for hypocalcemia after PTX were examined through logistic regression analysis. The survival curve was made by Kaplan-Meier method, and the difference of cumulative survival rate between the two groups was compared by log-rank test.Results:A total of 98 maintenance hemodialysis patients with SHPT were enrolled. The levels of serum calcium, phosphorus, and intact parathyroid hormone (iPTH) after the operation decreased significantly than those of preoperation (all P<0.05). Multiple linear regression analysis showed age ( β=-0.160, P=0.030), iPTH ( β=0.004, P=0.025) and C-reactive protein ( β=0.186, P=0.011) were correlated with postoperative calcium requirement. Preoperative alkaline phosphatase ( OR=1.002, 95% CI 1.000-1.004, P=0.018) and hemoglobin ( OR=0.977, 95% CI 0.954-1.000, P=0.048) independently predicted the occurrence risk of postoperative hypocalcemia through multivariate logistic regression analysis. The recurrence rate of high calcium supplement group was higher than that of low calcium supplement group (10.26% vs 0, P=0.023) and there was no significant difference in all-cause mortality between the two groups (17.95% vs 5.08%, P=0.086). The recurrence rate between the hypocalcemia group and non-hypocalcemia group was no significantly different (8.3% vs 1.8%, P=0.451) and there was no significant difference in all cause mortality between the two groups (12.5% vs 12.7%, P=1.000). Kaplan-Meier survival curve showed that the cumulative survival rate between the two groups was no significantly different (log-rank test χ2=0.147, P=0.702). Conclusions:PTX is a safe and effective therapeutic method to reduce the level of iPTH and improve the metabolism of calcium and phosphorus in SHPT patients. Age, iPTH and C-reactive protein are correlated with the postoperative requirement of calcium in the first week. Preoperative alkaline phosphatase and hemoglobin are independent risk factors for postoperative hypocalcemia. Correcting preoperative electrolyte disorder, improving infection and anemia can reduce the incidence of hypocalcemia after PTX.

ObjectiveTo investigate the mechanism by which Shenbai Jiedu prescription （SBJDF） inhibits the proliferation of colorectal cancer （CRC） HCT116 cells. MethodAfter 48 h treatment of HCT116 cells with SBJDF （0， 0.25， 0.5， 1， 2， 4 g·L^-1）， the viability of HCT116 cells were determined by methyl thiazolyl tetrazolium （MTT） colorimetry. Following the classification of cells into blank control group and SBJDF （1， 2， 4 g·L^-1） groups， the effect of SBJDF on HCT116 cell morphology was observed under an inverted microscope. The effects of SBJDF on the proliferation of HCT116 cells and mitochondrial membrane potential （Δψm） were detected by colony formation assay and JC-1 probe， respectively. The flow cytometry was then performed for determining cell cycle distribution and apoptosis. The effects of SBJDF on cell cycle-， apoptosis-， and nuclear factor kappa-B （NF-κB） signaling pathway-related proteins were determined by Western blot. ResultSBJDF effectively inhibited the vitality of HCT116 cells and changed their morphology in a concentration-dependent manner. Compared with the blank control group， SBJDF at 1， 2， 4 g·L^-1 significantly reduced cell colony formation （P<0.05， P<0.01），and SBJDF at 2 and 4 g·L^-1 arrested the HCT116 cell cycle at G₀/G₁ phase （P<0.05， P<0.01）. Compared with the blank control group， SBJDF at 1， 2， 4 g·L^-1 remarkably down-regulated the protein expression of CyclinD₁ （P<0.05， P<0.01）. SBJDF at 2 and 4 g·L^-1 lowered the CyclinA₂ and cyclin-dependent kinase 4 （CDK4） （P<0.05， P<0.01）. SBJDF at 4 g·L^-1 reduced the cyclin-dependent kinase 1 （CDK1） （P<0.01）. Compared with the blank control group， SBJDF at 2 and 4 g·L^-1 induced HCT116 cell apoptosis， down-regulated the protein expression of anti-apoptosis-related proteins Bcl-2 and Bcl-xl as well as the NF-κB signaling pathway-related proteins IκB kinase α （IKKα），inhibitor α of NF-κB （IκBα），and phospho-NF-κB p65 （p-p65） （P<0.05， P<0.01）， and diminished the mitochondrial membrane potential of HCT116 cells. ConclusionSBJDF inhibits the proliferation of HCT116 cells， which may be related to its inhibition of the activation of NF-κB signaling pathway and the induction of cell cycle arrest and apoptosis.
