OBJECTIVES: To explore the underlying pharmacological mechanisms and its potential effects of Chinese medicine herbal formula Sini Powder (SNP) on hepatocellular carcinoma (HCC). METHODS: The active components of SNP and their in vivo distribution were identified using ultraperformance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry. Construction of component-target-disease networks, protein-protein interaction network, Gene Ontology function and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis, and molecular docking were employed to analyze the active components and anti-HCC mechanisms of SNP. Cell viability assay and wound healing assay were utilized to confirm the effect of SNP-containing serum (2.5%, 5.0%, 10%, 20%, and 40%), isoprenaline or propranolol (both 10, 100, and 1,000 µ mol/L) on proliferation and migration of HepG 2 or Huh7 cells. Meanwhile, the effect of isoprenaline or propranolol on the β 2 adrenergic receptor (ADRB2) mRNA expression on HepG2 cells were measured by real-time quantitative reverse transcription (RT-qPCR). Mice with subcutaneous tumors were either subjected to chronic restraint stress (CRS) followed by SNP administration (364 mg/mL) or directly treated with SNP (364 mg/mL). These two parallel experiments were performed to validate the effects of SNP on stress responses. Stress-related proteins and hormones were quantified using RT-qPCR, enzyme-linked immunosorbent assay, and immunohistochemistry. Metagenomic sequencing was performed to confirm the influence of SNP on the gut microbiota in the tumor-bearing CRS mice. RESULTS: The distribution of the 12 active components of SNP was confirmed in various tissues and feces. Network pharmacology analysis confirmed the anti-HCC effects of the 5 active components. The potential anti-HCC mechanisms of SNP may involve the epidermal growth factor receptor (EGFR), proto-oncogene tyrosine-protein kinase Src (SRC) and signal transducer and activator of transcription 3 (STAT3) pathways. SNP-containing serum inhibited the proliferation of HepG2 and Huh7 cells at concentrations of 2.5% and 5.0%, respectively, after 24 h of treatment. Furthermore, SNP suppressed tumor progression in tumor-bearing mice exposed to CRS. SNP treatment also downregulated the expressions of stress-related proteins and pro-inflammatory cytokines, primarily by modulating the gut microbiota. Specifically, the abundance of Alistipes and Prevotella, which belong to the phylum Bacteroidetes, increased in the SNP-treated group, whereas Lachnospira, in the phylum Firmicutes, decreased. CONCLUSION SNP can combat HCC by alleviating stress responses through the regulation of gut microbiota.

OBJECTIVE: This study aimed to explore the interplay between the life-course body mass index (BMI) trajectories and insulin resistance (IR) on incident diabetes. METHODS: This longitudinal cohort included 2,336 participants who had BMI repeatedly measured 3-8 times between 1989 and 2009, as well as glucose and insulin measured in 2009. BMI trajectories were identified using a latent class growth mixed model. The interplay between BMI trajectories and IR on diabetes was explored using the four-way effect decomposition method. Logistic regression and mediation models were used to estimate the interaction and mediation effects, respectively. RESULTS: Three distinct BMI trajectory groups were identified: low-stable ( n = 1,625), medium-increasing ( n = 613), and high-increasing ( n = 98). Both interaction and mediation effects of BMI trajectories and IR on incident diabetes were significant ( P < 0.05). The proportion of incident diabetes was higher in the IR-obesity than in the insulin-sensitivity (IS) obesity group (18.9% vs. 5.8%, P < 0.001). After adjusting for covariates, the odds ratios (95% confidence intervals) of the IR, IS-obesity, and IR-obesity groups vs. the normal group were 3.22 (2.05, 5.16), 2.05 (1.00, 3.97), and 7.98 (5.19, 12.62), respectively. IR mediated 10.7% of the total effect of BMI trajectories on incident diabetes ( P < 0.001). CONCLUSION We found strong interactions and weak mediation effects of IR on the relationship between life-course BMI trajectories and incident diabetes. IS-obesity is associated with a lower risk of incident diabetes than IR-obesity.

BACKGROUND:Kidney deficiency is the main pathogenesis of osteoporosis.To study the relationship between the two major syndrome types of kidney deficiency,Kidney-Yang deficiency and Kidney-Yin deficiency,is beneficial for the development of clinical diagnosis and treatments based on the combination of disease and syndrome. OBJECTIVE:To evaluate the biomechanical differences of the rat femurs with Kidney-Yang deficiency and Kidney-Yin deficiency caused by Yougui pills,and to demonstrate the scientific efficacy of medication based on the combination of disease and syndrome in osteoporosis from a biomechanical perspective. METHODS:The bilateral ovaries of 60 female Sprague-Dawley rats were surgically removed to establish an ovariectomized osteoporosis model.At 10 weeks after modeling,all the rats were randomly divided into a Kidney-Yang deficiency group(n=30)and a Kidney-Yin deficiency group(n=30).Rats with Kidney-Yang deficiency were given gluteal intramuscular injection of hydrocortisone,while rats with Kidney-Yin deficiency were orally administered with thyroid tablet suspension,once a day,for 14 consecutive days.After successful modeling,20 rats in each group were given a suspension of Yougui pills by gavage once a day for 12 consecutive weeks and the remaining 10 rats were used as the control group without intervention.After gavage,the microstructural parameters of the bone were measured using Micro-CT scanning.Three-point bending,finite element simulation,femoral head compression,and surface indentation distribution experiments of the femurs were performed on a mechanical testing machine. RESULTS AND CONCLUSION:Micro-CT revealed that the femoral bone density,bone volume fraction,bone surface density,trabecular number,and trabecular separation were improved in the Kidney-Yin deficiency+Yougui pills group compared with the Kidney-Yin deficiency group(P＜0.05);the femoral bone volume fraction,bone surface density,trabecular number,and trabecular thickness were improved in the Kidney-Yang deficiency+Yougui pills group compared with the Kidney-Yang deficiency group(P＜0.05).The three-point bending experiment showed that the femur elastic modulus,maximum bending strength and bending fracture strength were decreased(P＜0.05)and toughness was increased(P＜0.05)in the Kidney-Yang deficiency+Yougui pills group compared with the Kidney-Yang deficiency group.Finite element simulation showed that Yougui pills could significantly improve the bending resistance of the femurs in the Kidney-Yang deficiency group,but had no significant effect on the Kidney-Yin deficiency group.The femoral head compression experiments showed that Yougui pills could enhance the ability of the femoral head to resist deformation in the Kidney-Yang deficiency group,but there was no significant difference in the effect of Yougui pills on the surface properties of the femoral head in the Kidney-Yin deficiency group and the Kidney-Yang deficiency group.To conclude,Yougui pills can significantly enhance the biomechanical properties of the osteoporotic bones with Kidney-Yang deficiency,but have no significant effect on the osteoporotic bone with Kidney-Yin deficiency.

Objective To study the inhibitory effect of Huidu Yinhua powder from the Orthodox Manual of External Medicine on methicillin-resistant Staphylococcus aureus(MRSA),virulence factor α-hemolysin(Hla)activity,and biofilm formation,and to explore the optimal ratios of Huidu Yinhua powder and provide experimental support for its use.Methods The inhibitory effects of Huidu Yinhua powder and the herbs in the formula on USA300 were analyzed by the minimum inhibitory concentration(MIC),minimum bactericidal concentration(MBC),and disk diffusion assay(K-B method).Hemolysis,neutralization,oligomerization,and Western blot assays were used to verify in which form the drug inhibits the activity of virulence factor α-hemolysin(Hla).A biofilm assay was performed to evaluate the inhibitory effect of Huidu Yinhua powder on biofilm.Orthogonal experiments were performed to explore the optimal ratio of Huidu Yinhua powder.Results Huidu Yinhua powder inhibited the MRSA strain with a MIC90 of 64 mg/mL and an MBC of 256 mg/mL with antibacterial circle diameter of(7.50±0.50)mm.Huidu Yinhua powder inhibited Hla activity by inhibiting Hla secretion.The minimum effective concentration(MEC)was 16 mg/mL,and the MEC of biofilm was 8 mg/mL.In Huidu Yinhua powder,honeysuckle and astragalus only affected the hemolytic activity of MRSA and biofilm formation without inhibiting bacterial growth.The hemolytic activity and biofilm of MEC were both 32 mg/mL.Glycyrrhiza had a strong bacterial inhibitory capacity with a MIC90 of 8 mg/mL and biofilm MEC of 1 mg/mL without showing inhibitory hemolytic activity at subinhibitory concentrations.The orthogonal experiment showed that,at a ratio of honeysuckle,astragalus,and glycyrrhiza in Huidu Yinhua powder of 1∶2∶4,the MIC90 was 16 mg/mL,MEC of hemolytic activity was 8 mg/mL and that of biofilm was 4 mg/mL,both of which were the lowest among the nine groups.Conclusions Huidu Yinhua powder affects the hemolytic activity and biofilm formation of MRSA at subinhibitory concentrations with the optimal ratio of honeysuckle,astragalus,and glycyrrhiza being 1∶2∶4.

Objective To investigate the mechanism of Gastrodiae Rhizoma-Salviae Miltiorrhizae Radix et Rhizoma drug pair in the treatment of hypertension based on the network pharmacology method and animal experiment verification.Methods(1)TCMSP,BATMAN and TCMIP databases were used to screen the active components and targets of Gastrodiae Rhizoma-Salviae Miltiorrhizae Radix et Rhizoma drug pair.The hypertension-related targets were obtained by searching the Drugbank,Genecard,TTD and Disgenet databases.The intersection(common target)of the active component target and the target related to hypertension disease was taken,and the obtained intersection target was the potential target of Gastrodiae Rhizoma-Salviae Miltiorrhizae Radix et Rhizoma drug pair for the treatment of hypertension.The active ingredients and their targets of Gastrodiae Rhizoma-Salviae Miltiorrhizae Radix et Rhizoma drug pair were imported into Cytoscape 3.9.1 software to construct a'Chinese medicines-active ingredients-targets'network and screen key active ingredients.The protein-protein interaction(PPI)network of potential targets was constructed to screen potential core targets.The Metascape platform was used to analyze the GO function and KEGG pathway enrichment of potential targets.The key active components and potential core targets were selected for molecular docking verification.(2)Thirty male spontaneously hypertensive rats(SHR)were randomly divided into model group,western medicine group(Candesartan Cilexetil,0.72 mg·kg-1)and low-,medium-and high-dose groups of Gastrodiae Rhizoma-Salviae Miltiorrhizae Radix et Rhizoma(2.25,4.50,9.00 g·kg-1).Another male WKY rats were selected as blank group,with 6 rats in each group,once a day for 8 weeks.The systolic blood pressure of rat tail artery was detected before administration and 2,4,6 and 8 weeks after drug intervention.The pathological changes of thoracic aorta were observed by HE staining.The protein expression levels of GRP78,CHOP and Caspase-12 in aorta abdominalis were detected by Western Blot.Results(1)A total of 83 active components of Gastrodiae Rhizoma-Salviae Miltiorrhizae Radix et Rhizoma were obtained,and 158 potential targets(intersection targets)for the treatment of hypertension were screened out.Five key active ingredients:p-hydroxybenzoic acid,4-hydroxybenzylamine,tanshinone I,tanshinone,γ-sitosterol;6 potential core targets:IL6,TNF,CASP3,JUN,PTGS2,IL1B;GO functional enrichment analysis obtained 1 826 biological process items,89 cell component items,and 199 molecular function items.KEGG pathway enrichment analysis obtained 186 pathways,mainly involving neuroactive ligand-receptor interaction,calcium signaling pathway,inflammatory response(such as TNF and MAPK signaling pathway),vascular protection(such as HIF-1 and cAMP signaling pathway),oxidative stress(such as PI3K-Akt signaling pathway)and other signaling pathways.Tanshinone I and tanshinone had strong binding force to 6 potential core targets,and γ-sitosterol had strong binding force to IL6,CASP3,JUN,PTGS2 and IL1B.(2)Compared with the blank group,the systolic blood pressure of the model group was significantly increased(P＜0.01).The thoracic aortic endothelial injury was obvious,the endothelial cell morphology was abnormal,swelling and exfoliated cells could be seen,the intima of the tissue was disordered,the intima structure was incomplete,and the intima was thickened.The protein expressions of GRP78,CHOP and Caspase-12 in abdominal aorta were significantly increased(P＜0.01).Compared with the model group,the systolic blood pressure of the rats in the administration group was significantly decreased(P＜0.01);the injury of thoracic aorta was alleviated,and the morphology,intima structure and thickness of endothelial cells were improved to varying degrees.The protein expressions of GRP78,CHOP and Caspase-12 in abdominal aorta were significantly decreased(P＜0.01).Conclusion Gastrodiae Rhizoma-Salviae Miltiorrhizae Radix et Rhizoma drug pair may act on core targets such as IL6,TNF,CASP3,JUN,PTGS2,and IL1B through key active components such as p-hydroxybenzoic acid,tanshinone,and γ-sitosterol,and regulate key signaling pathways such as TNF signaling pathway,MAPK signaling pathway,PI3K-Akt signaling pathway,and PERK signaling pathway to improve vascular endothelial dysfunction,inhibit endoplasmic reticulum stress,and lower blood pressure.

Background/Aims: Despite the high efficacy of direct-acting antivirals (DAAs), approximately 1–3% of hepatitis C virus (HCV) patients fail to achieve a sustained virological response. We conducted a nationwide study to investigate risk factors associated with DAA treatment failure. Machine-learning algorithms have been applied to discriminate subjects who may fail to respond to DAA therapy. Methods: We analyzed the Taiwan HCV Registry Program database to explore predictors of DAA failure in HCV patients. Fifty-five host and virological features were assessed using multivariate logistic regression, decision tree, random forest, eXtreme Gradient Boosting (XGBoost), and artificial neural network. The primary outcome was undetectable HCV RNA at 12 weeks after the end of treatment. Results: The training (n=23,955) and validation (n=10,346) datasets had similar baseline demographics, with an overall DAA failure rate of 1.6% (n=538). Multivariate logistic regression analysis revealed that liver cirrhosis, hepatocellular carcinoma, poor DAA adherence, and higher hemoglobin A1c were significantly associated with virological failure. XGBoost outperformed the other algorithms and logistic regression models, with an area under the receiver operating characteristic curve of 1.000 in the training dataset and 0.803 in the validation dataset. The top five predictors of treatment failure were HCV RNA, body mass index, α-fetoprotein, platelets, and FIB-4 index. The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of the XGBoost model (cutoff value=0.5) were 99.5%, 69.7%, 99.9%, 97.4%, and 99.5%, respectively, for the entire dataset. Conclusions Machine learning algorithms effectively provide risk stratification for DAA failure and additional information on the factors associated with DAA failure.

OBJECTIVE: Tumor-derived exosomes (TDEs) play crucial roles in intercellular communication. Hypoxia in the tumor microenvironment enhances secretion of TDEs and accelerates tumor metastasis. Jiedu recipe (JR), a traditional Chinese medicinal formula, has demonstrated efficacy in preventing the metastasis of hepatocellular carcinoma (HCC). However, the underlying mechanism remains largely unknown. METHODS: Animal experiments were performed to investigate the metastasis-preventing effects of JR. Bioinformatics analysis and in vitro assays were conducted to explore the potential targets and active components of JR. TDEs were assessed using nanoparticle tracking analysis (NTA) and Western blotting (WB). Exosomes derived from normoxic or hypoxic HCC cells (H-TDEs) were collected to establish premetastatic mouse models. JR was intragastrically administered to evaluate its metastasis-preventive effects. WB and lysosomal staining were performed to investigate the effects of JR on lysosomal function and autophagy. Bioinformatics analysis, WB, NTA, and immunofluorescence staining were used to identify the active components and potential targets of JR. RESULTS: JR effectively inhibited subcutaneous-tumor-promoted lung premetastatic niche development and tumor metastasis. It inhibited the release of exosomes from tumor cells under hypoxic condition. JR treatment promoted both lysosomal acidification and suppressed secretory autophagy, which were dysregulated in hypoxic tumor cells. Quercetin was identified as the active component in JR, and the epidermal growth factor receptor (EGFR) was identified as a potential target. Quercetin inhibited EGFR phosphorylation and promoted the nuclear translocation of transcription factor EB (TFEB). Hypoxia-impaired lysosomal function was restored, and secretory autophagy was alleviated by quercetin treatment. CONCLUSION JR suppressed HCC metastasis by inhibiting hypoxia-stimulated exosome release, restoring lysosomal function, and suppressing secretory autophagy. Quercetin acted as a key component of JR and regulated TDE release through EGFR-TFEB signaling. Our study provides a potential strategy for retarding tumor metastasis by targeting H-TDE secretion.

Objective: To examine the value of intravascular ultrasound (IVUS) for excimer laser ablation (ELA) combined with drug-coated balloon (DCB) in treating lower limb arteriosclerotic obliterans (ASO). Methods: As a prospective case series study, patients who underwent ELA combined with DCB for lower limb ASO with the guidance of IVUS from September 2021 to March 2022 at Department of Vascular Surgery, Zhongshan Hospital, Fudan University were enrolled prospectively. Lesion characteristics, procedure-related outcomes and complications were collected. The therapy outcomes were compared with baseline data by paired t test. Results: There were 8 males and 2 females, aged (72.0±5.9) years (range: 61 to 81 years). Of all the 11 lesions, there were 8 lesions in superficial femoral artery and 3 in popliteal artery. The lesion length was (7.0±2.4) cm (range: 3.2 to 9.8 cm). There were 4 chronic totally occlusion and 7 severe stenosis. All patients underwent the operation successfully. The technical success rate was 10/11. Bailout stenting was performed in one lesion because of flow-limiting dissection. Four lesions were grade 3 to 4 in peripheral artery calcium score system, and 9 lesions with calcification arc≥180°. Larger diameter drug-coated balloons were selected in 5 lesions after measurement of intravascular ultrasound. The follow-up time was (6.0±1.9) months (range: 3 to 9 months). The ankle-brachial index of the patient was significantly improved immediately after surgery (0.97±0.13 vs. 0.48±0.18, t=-7.60, P<0.01) and at 3 months after surgery (0.95±0.12 vs. 0.48±0.18, t=-7.17, P<0.01). The 3-month primary patency rate was 11/11, the target lesion reintervention was 0 and ulcer healing rate was 3/4. Conclusion: IVUS assisted ELA in the treatment of lower limb artery lesions is safe and effective in early stage.

OBJECTIVE: To investigate the safety and efficacy of reinforced radiculoplasty in the treatment of symptomatic sacral Tarlov cysts (TCs). METHODS: A retrospective analysis was performed on the clinical data and follow-up data of 71 patients with symptomatic sacral TCs who underwent reinforced radiculoplasty in the Neurosurgery Department of Peking University Third Hospital from June 2018 to March 2021. All the operations were performed under neuroelectrophysiological monitoring. Intraoperative cyst exploration, partial resection of the cyst wall, narrowing of the leak, nerve root sleeve radiculoplasty and artificial dural reinforcement were performed. The incidence of postoperative complications and new neurological dysfunction was analyzed. Visual analogue scale (VAS) was used to assess the changes of pain before and after surgery. The Japanese Orthopedics Association (JOA) low back pain score was used to evaluate the changes in nerve function before and after surgery. RESULTS: In the study, 71 patients had 101 TCs, 19 (18.8%) TCs originated from the left S1 nerve, 26 (25.7%) originated from the left S2 nerve, 3 (3.0%) originated from the left S3 nerve, 14 (13.9%) originated from the right S1 nerve, 33 (32.7%) originated from the right S2 nerve, 6 (5.9%) originated from the right S3 nerve, all the TCs underwent reinforced radiculoplasty. Deep infection (1 case), subcutaneous effusion (1 case), fat li-quefaction (1 case) and urinary tract infection (4 cases) were recorded postoperatively. The patients were followed up for 12-43 months (median, 26 months). Two cases had new urinary retention after operation, and the catheter was removed at the end of the first and second months respectively. One case had new fecal weakness, which improved after 3 months. Compared with preoperation, VAS decreased significantly at the last follow-up [median, 6 (4-9) vs. 1 (0-5), Z=-7.272, P < 0.001], JOA score increased significantly [median, 20 (16-25) vs. 27 (18-29), Z=-7.265, P < 0.001]. There were 18 cured cases (25.4%), 41 excellent cases (57.7%), 8 effective cases (11.3%), and 4 invalid cases (5.6%). The total efficiency was 94.4% (67/71). Two (1.98%) cysts recurred. CONCLUSION For patients with symptomatic sacral TCs, reinforced radiculoplasty can significantly improve the pain and nerve function, which is safe and reliable.

Growing clinical evidence shows that Qufeng Gutong Cataplasm may exert a significant analgesic effect. However, the pharmacological characteristics and mechanisms underlying this prescription are still unclear. In the current study, a "disease-syndrome-symptom-formula" association network analysis was performed to explore the pharmacological characteristics and mechanisms of Qufeng Gutong Cataplasm against osteoarthritis (OA), neuropathic pain (NP), chronic inflammatory pain (CIP) and myofascial pain syndrome (MPS) by integrating clinical phenomics data, transcriptomics data and biological interaction network mining. As a result, the three functional modules (Qufeng Sanhan-QFSHG, Shujin Huoxue-SJHXG and Xiaozhong Zhitong-XZZTG) enriched by the drug network targets were all related to the pharmacological effects of Qufeng Gutong Cataplasm, including dispersing cold and relieving pain, activating blood and relieving pain, reducing swelling and relieving pain. In addition, the main pharmacological effects of QFSHG and XZZTG were dispelling wind and dispersing cold and dehumidifying, promoting Qi and reducing swelling and relieving pain, respectively. In terms of reversing the imbalance of "immune-inflammation-vascular axis", the main pharmacological effects of SJHXG were regulating the liver and promoting Qi, activating blood circulation and removing stasis. Mechanically, the key network targets of Qufeng Gutong Cataplasm against OA, NP, CIP and MPS may play a therapeutic role in relieving hyperalgesia and paresthesia by reversing the "neuro-endocrine-immune" imbalance system during the occurrence and progression of diseases. In conclusion, our data indicate that Qufeng Gutong Cataplasm may relieve the pain and wind-cold-dampness arthralgia syndrome related symptoms by regulating the "neuro-endocrine-immune" system, neurological and endocrine disorders and reversing the imbalance of "immunity-inflammation". The relevant results may provide a network-based evidence for clinical positioning of Qufeng Gutong Cataplasm, and offer a direction for further clinical and experimental validation.
