This study identified blood-entering components of Anshen Dropping Pills and explored their anti-insomnia effects and mechanisms. The main blood-entering components of Anshen Dropping Pills were detected and identified by UPLC-Q-TOF-MS/MS. The rationality of the formula was assessed by using enrichment analysis based on the relationship between drugs and symptoms, and core targets of its active components were selected as the the potential anti-insomnia targets of Anshen Dropping Pills through network pharmacology analysis. Furthermore, protein-protein interaction(PPI) network, Gene Ontology(GO) enrichment analysis, and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway analysis were performed on the core targets. An active component-core target network for Anshen Dropping Pills was constructed. Finally, the effects of low-, medium-, and high-dose groups of Anshen Dropping Pills on sleep episodes, sleep duration, and sleep latency in mice were measured by supraliminal and subliminal pentobarbital sodium experiments. Moreover, total scores of the Pittsburgh sleep quality index(PSQI) scale was used to evaluate the changes before and after the treatment with Anshen Dropping Pills in a clinical study. The enrichment analysis based on the relationship between drugs and symptoms verified the rationality of the Anshen Dropping Pills formula, and nine blood-entering components of Anshen Dropping Pills were identified by UPLC-Q-TOF-MS/MS. The network proximity revealed a significant correlation between eight components and insomnia, including magnoflorine, liquiritin, spinosin, quercitrin, jujuboside A, ginsenoside Rb_3, glycyrrhizic acid, and glycyrrhetinic acid. Network pharmacology analysis indicated that the major anti-insomnia pathways of Anshen Dropping Pills involved substance and energy metabolism, neuroprotection, immune system regulation, and endocrine regulation. Seven core genes related to insomnia were identified: APOE, ALB, BDNF, PPARG, INS, TP53, and TNF. In summary, Anshen Dropping Pills could increase sleep episodes, prolong sleep duration, and reduce sleep latency in mice. Clinical study results demonstrated that Anshen Dropping Pills could decrease total scores of PSQI scale. This study reveals the pharmacodynamic basis and potential multi-component, multi-target, and multi-pathway effects of Anshen Dropping Pills, suggesting that its anti-insomnia mechanisms may be associated with the regulation of insomnia-related signaling pathways. These findings offer a theoretical foundation for the clinical application of Anshen Dropping Pills.

Hepatocellular carcinoma(HCC), the third leading cause of cancer-related death worldwide, is characterized by high mortality and recurrence rates. Common treatments include hepatectomy, liver transplantation, ablation therapy, interventional therapy, radiotherapy, systemic therapy, and traditional Chinese medicine(TCM). While exhibiting specific advantages, these approaches are associated with varying degrees of adverse effects. To alleviate patients' suffering and burdens, it is crucial to explore additional treatments and elucidate the pathogenesis of HCC, laying a foundation for the development of new TCM-based drugs. With emerging research on gut microbiota, it has been revealed that microbiota plays a vital role in the development of HCC by influencing intestinal barrier function, microbial metabolites, and immune regulation. TCM, with its multi-component, multi-target, and multi-pathway characteristics, has been increasingly recognized as a vital therapeutic treatment for HCC, particularly in patients at intermediate or advanced stages, by prolonging survival and improving quality of life. Recent global studies demonstrate that TCM exerts anti-HCC effects by modulating gut microbiota, restoring intestinal barrier function, regulating microbial composition and its metabolites, suppressing inflammation, and enhancing immune responses, thereby inhibiting the malignant phenotype of HCC. This review aims to elucidate the mechanisms by which gut microbiota contributes to the development and progression of HCC and highlight the regulatory effects of TCM, addressing the current gap in systematic understanding of the "TCM-gut microbiota-HCC" axis. The findings provide theoretical support for integrating TCM with western medicine in HCC treatment and promote the transition from basic research to precision clinical therapy through microbiota-targeted drug development and TCM-based interventions.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

OBJECTIVE: To determine whether monotropein has an anticancer effect and explore its potential mechanisms against colorectal cancer (CRC) through network pharmacology and molecular docking combined with experimental verification. METHODS: Network pharmacology and molecular docking were used to predict potential targets of monotropein against CRC. Cell counting kit assay, plate monoclonal assay and microscopic observation were used to investigate the antiproliferative effects of monotropein on CRC cells HCT116, HT29 and LoVo. Flow cytometry and scratch assay were used to analyze apoptosis and cell cycle, as well as cell migration, respectively in HCT116, HT29, and LoVo cells. Western blotting was used to detect the expression of proteins related to apoptosis, cell cycle, and cell migration, and the expression of proteins key to the Akt pathway. RESULTS: The Gene Ontology and Reactome enrichment analyses indicated that the anticancer potential of monotropein against CRC might be involved in multiple cancer-related signaling pathways. Among these pathways, RAC-beta serine/threonine-protein kinase (Akt1, Akt2), cyclin-dependent kinase 6 (CDK6), matrix metalloproteinase-9 (MMP9), epidermal growth factor receptor (EGFR), cell division control protein 42 homolog (CDC42) were shown as the potential anticancer targets of monotropein against CRC. Molecular docking suggested that monotropein may interact with the 6 targets (Akt1, Akt2, CDK6, MMP9, EGFR, CDC42). Subsequently, cell activity of HCT116, HT29 and LoVo cell lines were significantly suppressed by monotropein (P<0.05). Furthermore, our research revealed that monotropein induced cell apoptosis by inhibiting Bcl-2 and increasing Bax, induced G₁-S cycle arrest in colorectal cancer by decreasing the expressions of CyclinD1, CDK4 and CDK6, inhibited cell migration by suppressing the expressions of CDC42 and MMP9 (P<0.05), and might play an anticancer role through Akt signaling pathway. CONCLUSION Monotropein exerts its antitumor effects primarily by arresting the cell cycle, causing cell apoptosis, and inhibiting cell migration. This indicates a high potential for developing novel medication for treating CRC.

Objective To construct reference ranges of cardiac size and morphologic parameters in low-risk fetuses at 28-39 gestational weeks using two-dimensional speckle tracking technique.Methods A prospective collection of 453 low-risk singleton pregnancies with echocardiography at Obstetrics and Gynecology Hospital,Fudan University was used to assess the size(length,width,and area)and morphology(sphericity index,i.e.,the ratio of length to width)of the fetal four-chamber view and two ventricles using two-dimensional speckle tracking technique.Repeated inter-and intra-observer agreement of measurements was assessed using the intraclass correlation coefficients(ICCs).Statistical analysis of cardiac measurement parameters was performed to establish reference ranges of values for cardiac size and morphology in low-risk fetuses.Results The inter-and intra-group ICCs for reproducibility tests of fetal cardiac parameters measurements were 0.691 to 0.980.Fetal four-chamber view and ventricular size increased with gestational week(all P<0.001),the end-diastolic length of the left ventricle was larger than that of the right ventricle,and the end-diastolic diameter was smaller than that of the right ventricle(both P<0.001),while there was no significant difference in the end-diastolic area of the two ventricles(P= 0.050).The spherical index of four-chamber view did not correlate with gestational week(P=0.811).The sphericity index of the basal and intermediate segments of the left ventricle was greater than that of the right ventricle,and the sphericity index of the apical segment was less than that of the right ventricle,the differences were statistically significant(all P<0.01).Conclusion The two-dimensional speckle tracking technique for measuring fetal cardiac parameters has good reproducibility.The reference ranges for cardiac size and morphology in low-risk fetuses developed in this study will be useful for prenatal evaluation of cardiac remodeling.

This study aims to investigate the effect of Linggui Zhugan Decoction(LGZGD) on autophagy in the mouse model of chronic heart failure(CHF) induced by myocardial infarction(MI), as well as the regulatory effect of LGZGD on the hypoxia-inducible factor-1α(HIF-1α)/heme oxygenase-1(HO-1) signaling pathway, based on bioinformatics and animal experiments. The active ingredients and corresponding targets of LGZGD were retrieved from the Traditional Chinese Medicine Systems Pharmacology and Analysis Database, and GEO, GeneCards, and DisGeNET were searched for the disease targets. Cytoscape was used to establish a "drug-component-target" network. The protein-protein interaction(PPI) network analysis was performed on STRING. R language was used for Gene Ontology(GO) and Kyoto Encycloperfia of Genes and Genomes(KEGG) enrichment analyses. Molecular docking was adopted to validate the core targets. The mouse model of MI-induced CHF was established by surgical ligation of the left anterior descending coronary artery. The modeled mice were assigned into the sham, model, low-, medium-, and high-dose(2.34, 4.68, and 9.36 g·kg~(-1), respectively) LGZGD, and captopril(3.25 mg·kg~(-1)) groups. After continuous administration for 6 weeks, a Doppler ultrasound imaging system was used to examine the heart function indicators: left ventricular ejection fraction(LVEF), left ventricular fractional shortening(LVFS), left ventricular end-systolic dimension(LVIDs), and left ventricular end-diastolic dimension(LVIDd). The myocardial tissue was stained with hematoxylin-eosin for the observation of morphological changes. The mRNA levels of microtubule-associated protein 1 light chain 3 beta(LC3B), Beclin1, p62, HIF-1α, and HO-1 in the myocardial tissue were determined by RT-qPCR. The protein levels of LC3B, beclin1, p62, autophagy-related protein 5(ATG5), HIF-1α, and HO-1 were determined by Western blot. The results showed that 103 active components of LGZGD, corresponding to 224 targets, were obtained. A total of 3 485 and 6 165 targets related to MI and CHF, respectively, were retrieved. The GSE16499 dataset obtained 3 263 differentially expressed genes. There were 31 common targets. The top 3 core active components were quercetin, naringenin, and 1-methoxyphaseollidin. The topology analysis results showed that the core targets were MAPK3, HMOX1(HO-1), MYC, ADRB2, PPARD, and HIF1A(HIF-1α). The molecular docking results showed strong binding between the core targets and the main active components of LGZGD. LGZGD significantly improved the heart function and alleviated the pathological changes in the myocardial tissue of mice. Western blot and RT-qPCR results showed that the HIF-1α/HO-1 signaling pathway and autophagy were activated in the model group. LGZGD up-regulated the levels of LC3B, Beclin1, ATG5, HIF-1α, and HO-1 while down-regulating the mRNA and protein levels of p62. In summary, LGZGD can enhance autophagy and improve the heart function in the mouse model of CHF after MI by upregulating the HIF-1α/HO-1 signaling pathway.

Objective:To investigate the clinical efficacy of modified biliary-intestinal anasto-mosis by pancreaticoduodenectomy and influencing factors of postoperative biliary leakage.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopatholo-gical data of 165 patients with benign and malignant diseases around the ampullary who underwent pancreaticoduodenectomy in the Affiliated Hospital of Inner Mongolia Medical University from June 2014 to October 2020 were collected. There were 92 males and 73 females, aged (59±10)years. Of the 165 patients, 44 patients undergoing modified biliary-intestinal anastomosis within pancreatico-duodenectomy were divided into the modified group, and 121 patients undergoing traditional biliary-intestinal anastomosis within pancreaticoduodenectomy were divided into the traditional group. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) intraoperative and postoperative situations; (3) analysis of influencing factors of biliary leakage after pancreaticoduodenectomy. Propensity score matching was done by the 1:1 nearest neighbor matching method, with the caliper setting as 0.05. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Univariate analysis was conducted using the corresponding statistical methods based on data type. All indicators in univariate analysis were included in multivariate analysis. Multivariate analysis was conducted using the Logistic regression model. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of the 165 patients, 72 cases were successfully matched, including 36 cases in the modified group and 36 cases in the traditional group, respectively. The elimination of jaundice, preoperative reduction of jaundice and hypertension confounding bias ensured comparability between the two groups after propensity score matching. (2) Intraoperative and postoperative situations. All patients in the two groups underwent surgery successfully. The operation time, postoperative pathological type (lower bile duct cancer, pancreatic head cancer, pancreatic cystic tumor, chronic pancreatitis, duodenal cancer), time of no drainage fluid in the drainage tube around biliary-intestinal anastomosis were 371(270,545)minutes, 6, 12, 1, 2, 15, (12±7)days in patients of the modified group, versus 314(182,483) minutes, 13, 14, 1, 4, 4, (16±8)days in patients of the traditional group, showing significant differences in the above indicators between the two groups ( Z=-3.54, χ2=10.01, t=-2.34, P<0.05). Cases with postoperative grade A biliary leakage was 0 in patients of the modified group, versus 6 in patients of the traditional group, showing a significant difference between the two groups ( P<0.05). Cases with postoperative grade B biliary leakage, cases with postoperative grade B pancreatic fistula, cases with postoperative bleeding, cases with abdominal infection, cases with incision infection, cases with delayed gastric emptying, cases undergoing unplanned readmission were 1, 0, 1, 4, 1, 5, 1 in patients of the modified group, versus 0, 1, 2, 5, 2, 5, 2 in patients of the traditional group, showing no significant difference in the above indicators between the two groups ( P>0.05). Cases with postoperative grade A pancreatic fistula, cases with overall complications, cases with Clavien-Dindo grade Ⅰ-Ⅱ complications, cases with Clavien-Dindo grade Ⅲ-Ⅳ complications were 6, 12, 6, 6 in patients of the modified group, versus 7, 14, 8, 6 in patients of the traditional group, showing no significant difference in the above indicators between the two groups ( χ2=0.09, 0.24, 0.36, 0.00, P>0.05). None of patient in the two groups had postoperative grade C biliary leakage and postoperative grade C pancreatic fistula. (3) Analysis of influencing factors of biliary leakage after pancreaticoduodenectomy. Results of multivariate analysis showed that preoperative reduction of jaundice and traditional biliary-intestinal anastomosis were independent risk factors for biliary leakage after pancreaticoduodenectomy ( odds ratio=11.37, 12.27, 95% confidence interval as 1.76-73.35, 1.14-131.23, P<0.05). Conclusions:Compared with traditional biliary-intestinal anastomosis, modified biliary-intestinal anastomosis within pancreaticoduodenectomy is safe and feasible. Preoperative reduction of jaundice and traditional biliary-intestinal anastomosis are independent risk factors for biliary leakage after pancreaticoduodenectomy.

OBJECTIVE: Flavonoids are the bioactive compounds in safflower (Carthamus tinctorius), in which chalcone synthase (CHS) is the first limiting enzyme. However, it is unclear that which chalcone synthase genes (CHSs) are participated in flavonoids biosynthesis in C. tinctorius. In this study, the CHSs in the molecular characterization and enzyme activities were investigated. METHODS: Putative chalcone biosynthase genes were screened by the full-length transcriptome sequences data in C. tinctorius. Chalcone biosynthase genes in C. tinctorius (CtCHSs) were cloned from cDNA of flowers of C. tinctorius. The cloned gene sequences were analyzed by bioinformatics, and their expression patterns were analyzed by real-time PCR (RT-PCR). The protein of CtCHS in the development of flowers was detected by polyclonal antibody Western blot. A recombinant vector of CtCHS was constructed. The CtCHS recombinant protein was induced and purified to detect the enzyme reaction (catalyzing the reaction of p-coumaryl-CoA and malonyl-CoA to produce naringin chalcone). The reaction product was detected by HPLC and LC-MS. RESULTS: Two full-length CtCHS genes were successfully cloned from the flowers of safflower (CtCHS1 and CtCHS3), with gene lengths of 1525 bp and 1358 bp, respectively. RT-PCR analysis showed that both genes were highly expressed in the flowers, but the expression of CtCHS1 was higher than that of CtCHS3 at each developmental stage of the flowers. WB analysis showed that only CtCHS1 protein could be detected at each developmental stage of the flowers. HPLC and LC-MS analyses showed that CtCHS1 could catalyze the conversion of p-coumaryl-CoA and malonyl-CoA substrates to naringin chalcone. CONCLUSION CtCHS1 is involved in the biosynthesis of naringin chalcone in safflower.
