ObjectiveTo observe the clinical efficacy of Gandouling decoction combined with neuromuscular electrical stimulation （NMES） in the treatment of dysphagia in Wilson disease （WD） with combined phlegm and stasis. MethodsA total of 80 WD patients with dysphagia due to combined phlegm and stasis treated in the Department of Encephalopathy， the First Affiliated Hospital of Anhui University of Chinese Medicine were randomized into a control group and an observation group， with 40 patients in each group. In addition， 40 healthy volunteers were recruited as the normal group. The control group was treated with basic copper drainage combined with NMES. The observation group was treated with Gandouling Decoction on the basis of the therapy in the control group. Each course of treatment lasted for 8 days， and the patients were treated for a total of 4 courses. All subjects underwent video fluoroscopic swallowing study （VFSS） before and after treatment. During the examination， contrast agents with 4 different characters were used for the swallowing action， and the passing time was recorded. The TCM syndrome score， water swallow test score， standard swallowing assessment （SSA） score， and 24-h urinary copper level before and after treatment were analyzed. ResultsWhen performing VFSS， the passing time of contrast agents of different characters in the oral stage was longer in the WD group than in the normal group （P<0.01）， while it had no significant difference in the pharyngeal stage. After treatment， the passing time in the oral stage shortened in the control and observation groups （P<0.01）， and the observation group outperformed the control group （P<0.01）. After treatment， both the control and observation groups showed declines in TCM syndrome score and SSA score （P<0.01） and an increase in water swallow test score （P<0.01）， and the changes were more obvious in the observation group than in the control group （P<0.01）. In addition， the treatment in the control and observation groups elevated the 24-h urinary copper level （P<0.01）， and the elevation in the observation group was more obvious than that in the control group （P<0.01）. Neither group showed obvious adverse reaction. ConclusionGandouling decoction combined with NMES can significantly ameliorate dysphagia in WD patients with the syndrome of combined phlegm and stasis regarding the TCM syndrome score， water swallow test score， and SSA score， demonstrating definite clinical efficacy and high safety.

Five novel nor-eremophilane-type sesquiterpenoids, peniroqueforins E-H and J (1-4 and 7), two new eremophilane-type sesquiterpenoids, peniroqueforins I and K (5 and 8), and a new eudesmane-type sesquiterpenoid, peniroqueforin L (9), along with four known compounds (6 and 10-12), were isolated and characterized from fungus Penicillium roqueforti (P. roqueforti). The structures and absolute configurations of these compounds were determined through comprehensive spectroscopic analyses, electronic circular dichroism (ECD) data analyses, and single-crystal X-ray diffraction methods. The anti-multi-drug resistance (MDR) cancer activity of these compounds was evaluated using SW620/Ad300 cells. Notably, the half maximal inhibitory concentration (IC₅₀) value of paclitaxel (PTX) combined with 1 in SW620/Ad300 cells was 50.36 nmol·L^-1, which was 65-fold more potent than PTX alone (IC₅₀ 3.26 μmol·L^-1). Subsequent molecular docking studies revealed an affinity between compound 1 and P-glycoprotein (P-gp), suggesting that this nor-eremophilane-type sesquiterpenoid (1) could serve as a potential lead for MDR reversal in cancer cells through P-gp inhibition.

Objective To investigate the quality and in vitro release behavior of the sirolimus self-microemulsion-mesoporous silicon sustained release tablets and provide a basis for further research and development of related preparations. Methods The hardness, brittleness and content uniformity of the sustained-release tablets were tested refer to Pharmacopoeia of the People’s Republic of China 2020. Different diameters （10, 11, 12 mm）, different hardness （50, 70, 90 N）, different speed （50, 75, 100 r/min）, different dissolution methods （pulp method, basket method） were investigated. The release conditions of the sustained-release tablets with different pH solution （distilled water solution and 0.4% SDS solution with pH of 1.2, 4.5 and 6.8, respectively） and the in vitro release conditions of the sustained-release tablets were observed. Results The hardness, brittleness and content uniformity of the self-made sustained-release tablets were qualified; different diameters and dissolution methods had no effect on the drug release behavior of the sustained-release tablets in vitro, while the different hardness, different rotational speed and the different pH release media had certain effects. Conclusion The sirolimus self-microemulsion-mesoporous silicon sustained release tablets had good sustained-release effect in vitro and was deserved to further study.

In recent years, research on the quality and safety detection of bear bile powder has mainly involved three aspects. First, the identification of active components and substitutes. Quantitative analysis of bile acids and other components is performed using HPLC, HPLC-tandem mass spectrometry, and other techniques, combined with near-infrared spectroscopy, X-ray diffraction, and polymerase chain reaction to identify adulteration. Isotope fingerprint analysis and glycosylation modification detection are used to distinguish natural products from biosynthetic substitutes, revealing significant differences in δ13C values and the proportion of specific glycosylation modifications between natural bear bile powder and synthetic products. Second, the detection of veterinary drug residues, mainly based on ultra-high performance liquid chromatography-tandem mass spectrometry, which can screen over 100 types of residues, but targeted purification strategies are needed to address interference from the bile acid matrix. Thirdly, heavy metal detection, mainly using inductively coupled plasma mass spectrometry and atomic absorption spectrometry, has revealed that contamination is associated with the breeding environment, with significant regional differences. Related detection technologies are gradually evolving from single-target analysis to multi-modal and intelligent approaches. Existing research faces issues, such as matrix effect interference, lack of international standards, and ethical controversies. It is suggested that future efforts should focus on the interdisciplinary application of detection technologies, develop rapid detection methods such as non-invasive monitoring and microfluidic chips, promote the standardization and equivalence evaluation of synthetic alternatives, and establish a full-chain quality control system integrating spatially resolved mass spectrometry imaging, artificial intelligence, and big data.

ObjectiveTo explore the key molecules regulated by norcantharidin (NCTD) in colon cancer treatment.MethodsWe used cell counting kit-8 and 5-ethnyl-2′-deoxyuridine/Hoechst staining assays to study the effects of NCTD on cell proliferation in colon cancer. Annexin V-fluorescein isothiocyanate/propidium iodide staining was used to evaluate apoptosis, whereas Transwell assays were conducted to evaluate migration and invasion. We performed RNA sequencing to analyze the changes in gene expression after treatment. Differential analysis was performed using differential expression sequencing 2 (Deseq2) in R. Cytoscape was used to construct a competing endogenous RNA (ceRNA) network and Gene Expression Omnibus (GEO) datasets were used to validate sine oculis homeobox homolog 4 (SIX4) expression in colon cancer tissues. Furthermore, the prognostic potential of SIX4 was evaluated using receiver-operating characteristic curves. We conducted an immune infiltration analysis to explore the SIX4 relationship with the immune microenvironment in colon cancer. Finally, SIX4 expression, pan-cancer prognosis, tumor mutation burden (TMB) correlations, microsatellite instability (MSI), and mismatch repair (MMR) were analyzed.ResultsNCTD inhibited colon cancer cell proliferation (P .0001), induced apoptosis (P = .0007), and suppressed the migration and invasion of colon cancer cells. The H19/miR-193b-3p/SIX4 axis was identified as the key ceRNA network involved in the anticancer activity of NCTD. SIX4 is highly expressed in colon cancer tissues, shortening patient survival and affecting immune infiltration. A pan-cancer analysis showed that SIX4 overexpression affects the survival of various cancers. Finally, we correlated SIX4 expression with TMB, MSI, and MMR expression.ConclusionNCTD inhibits the malignant behaviour of colon cancer cells. SIX4 is abnormally expressed in multiple tumor types, significantly affecting the overall survival of patients with cancer, and is a core regulatory target of NCTD in the treatment of colon cancer.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Objective:In chronic hepatitis B (CHB) patients with previous 96-week treatment with tenofovir amibufenamide (TMF) or tenofovir disoproxil fumarate (TDF), we investigated the efficacy of sequential TMF treatment from 96 to 144 weeks.Methods:Enrolled subjects who were previously assigned (2:1) to receive either 25 mg TMF or 300 mg TDF with matching placebo for 96 weeks received extended or switched TMF treatment for 48 weeks. Efficacy was evaluated based on virological, serological, biological parameters, and fibrosis staging. Statistical analysis was performed using the McNemar test, t-test, or Log-Rank test according to the data. Results:593 subjects from the initial TMF group and 287 subjects from the TDF group were included at week 144, with the proportions of HBV DNA<20 IU/ml at week 144 being 86.2% and 83.3%, respectively, and 78.1% and 73.8% in patients with baseline HBV DNA levels ≥8 log10 IU/ml. Resistance to tenofovir was not detected in both groups. For HBeAg loss and seroconversion rates, both groups showed a further increase from week 96 to 144 and the 3-year cumulative rates of HBeAg loss were about 35% in each group. However, HBsAg levels were less affected during 96 to 144 weeks. For patients switched from TDF to TMF, a substantial further increase in the alanine aminotransferase (ALT) normalization rate was observed (11.4%), along with improved FIB-4 scores.Conclusion:After 144 weeks of TMF treatment, CHB patients achieved high rates of virological, serological, and biochemical responses, as well as improved liver fibrosis outcomes. Also, switching to TMF resulted in significant benefits in ALT normalization rates (NCT03903796).

Objective:In chronic hepatitis B (CHB) patients with previous 96-week treatment with tenofovir amibufenamide (TMF) or tenofovir disoproxil fumarate (TDF), we investigated the safety profile of sequential TMF treatment from 96 to 144 weeks.Methods:Enrolled subjects that previously assigned (2:1) to receive either 25 mg TMF or 300 mg TDF with matching placebo for 96 weeks received extending or switching TMF treatment for 48 weeks. Safety profiles of kidney, bone, metabolism, body weight, and others were evaluated.Results:666 subjects from the initial TMF group and 336 subjects from TDF group with at least one dose of assigned treatment were included at week 144. The overall safety profile was favorable in each group and generally similar between extended or switched TMF treatments from week 96 to 144. In subjects switching from TDF to TMF, the non-indexed estimated glomerular filtration rate (by non-indexed CKD-EPI formula) and creatinine clearance (by Cockcroft-Gault formula) were both increased, which were (2.31±8.33) ml/min and (4.24±13.94) ml/min, respectively. These changes were also higher than those in subjects with extending TMF treatment [(0.91±8.06) ml/min and (1.30±13.94) ml/min]. Meanwhile, switching to TMF also led to an increase of the bone mineral density (BMD) by 0.75% in hip and 1.41% in spine. On the other side, a slight change in TC/HDL ratio by 0.16 (IQR: 0.00, 0.43) and an increase in body mass index (BMI) by (0.54±0.98) kg/m 2 were oberved with patients switched to TMF, which were significantly higher than that in TMF group. Conclusion:CHB patients receiving 144 weeks of TMF treatment showed favorable safety profile. After switching to TMF, the bone and renal safety was significantly improved in TDF group, though experienceing change in metabolic parameters and weight gain (NCT03903796).
