Laparoscopic subtotal cholecystectomy (LSC) has been a safe and viable alternative to conversion to laparotomy in cases of severe cholecystitis. The objective of this study is to determine the utility of intraoperative choledochoscopy in LSC for the exploration of the gallbladder, cyst duct, and subsequent stone clearance of the cystic duct in cases of severe cholecystitis. A total of 72 patients diagnosed with severe cholecystitis received choledochoscopy-assisted laparoscopic subtotal cholecystectomy (CALSC). A choledochoscopy was performed to explore the gallbladder cavity and/or cystic duct, and to extract stones using a range of techniques. The clinical records, including the operative records and outcomes, were subjected to analysis. No LSC was converted to open surgery, and no bile duct or vascular injuries were sustained. All stones within the cystic duct were removed by a combination of techniques, including high-frequency needle knife electrotomy, basket, and electrohydraulic lithotripsy. A follow-up examination revealed the absence of residual bile duct stones, with the exception of one common bile duct stone, which was extracted via endoscopic retrograde cholangiopancreatography. In certain special cases, CALSC may prove to be an efficacious treatment for the management of severe cholecystitis. This technique allows for optimal comprehension of the situation within the gallbladder cavity and cystic duct, facilitating the removal of stones from the cystic duct and reducing the residue of the non-functional gallbladder remnant.

As traditional Chinese medicine (TCM) culture evolves, the academic thoughts of these practitioners, being a core component of TCM inheritance, are gradually shifting from traditional models to digital and intelligent approaches. However, this process faces challenges, including insufficient standardization of data collection and processing, low inheritance efficiency, and the risk of inheritance alienation. To address these issues, this paper proposed the construction of an intelligent platform following the "intelligence-transmission-modeling-linkage" path. "Intelligence" involves using smart perception technologies to accurately collect and classify diagnostic and therapeutic information from famous TCM practitioners, laying the foundation for digital inheritance; "transmission" focuses on leveraging artificial intelligence to mine and inherit the clinical experience of famous TCM practitioners, thereby establishing a "regional academic schools+group commonality" dynamic inheritance system; "modeling" integrates the academic thoughts and advantageous diseases of multiple schools to develop intelligent diagnostic and therapeutic models of famous TCM practitioners, resulting in personalized treatment plans; "linkage" involves constructing a clinical decision support system of famous TCM practitioners by integrating blockchain and generative intelligence, creating an AI digital avatar of TCM diagnostic and therapeutic knowledge. The "intelligence-transmission-modeling-linkage" intelligent inheritance model not only provides new ideas for the digital inheritance of TCM academic schools, but also offers strong support for the modernization and internationalization of TCM.

ObjectiveBased on the Huangdi Neijing,a traditional Chinese medicine(TCM)identification scale of five human qualities was constructed and applied in elderly people to evaluate its reliability and validity. MethodsBased on the original text of the Huangdi Neijing and a review of relevant ancient and modern literature, an identification scale of five human qualities was developed through Delphi expert interviews. Offline surveys were conducted to evaluate the feasibility,reliability,and validity of its application in elderly people,and the scale was evaluated and revised. ResultsThe scale of five human qualities is divided into five subscales:wood,fire,earth,metal,and water. Each subscale is divided into four dimensions:morphological structure,psychological characteristics,tolerance,and physiological characteristics,with a total of 75 items. The survey results in elderly people show that:(1) The recovery rate and completion rate are 100%,and the average filling time is 23.3 min. 85.5% of the samples are completed within the preset time. (2) Reliability analysis results:The homogeneity reliability of each subscale,Chronbach's α,ranges from 0.702 to 0.793. The scores of each subscale in the split-half reliability range from 0.758 to 0.841, indicating that the internal consistency of the scale is good. (3) Validity analysis results. Content validity:During the development stage of the scale,the item pool,dimensions,and structure of the scale are designed reasonably, and the content is complete. The evaluation of content validity shows that the item-level content validity index (I-CVI) ranges from 0.83 to 1.00, and the scale-level content validity index for universal agreement (S-CVI/UA) is 0.92,indicating good content validity of the scale. Construct validity extracts 22 common factors based on an eigenvalue of 1,with a contribution rate of 62.333% to the overall system. The number of common factors in the five subscales is 4,5,4,5,and 4,respectively,with contribution rates of 52.64%,53.376%,51.445%,51.359%,and 50.714%,respectively,indicating the required structure for physical fitness measurement in elderly people. ConclusionThe scale constructed in this study has high reliability and validity,and it is suitable for evaluating the physical condition of elderly people in TCM.

Separation and determination of chiral and achiral impurities in glimepiride tablets by supercritical fluid chromatography. Chiral and achiral impurities were separated on a ACQUITY UPC2 TrefoilTM CEL1 column (150 mm × 3.0 mm, 2.5 μm) maintained at 30 ℃ with the mobile phase containing a mixture of CO2 and methanol-isopropanol (1∶1) at 1 mL·min-1, and the detection wavelength was set at 228 nm. The back pressure was set at 13.8 MPa. The injection volume was 5 μL. In the chromatogram of the system suitability solution, the peaks elute in the following order: impurity Ⅳ, impurity Ⅴ, glimepiride, impurity Ⅲ, impurity Ⅰ and impurity Ⅱ. The six substances were separated successfully in 6 min using the proposed method with a resolution factor of 2.9, 1.6, 3.0, 2.0, 6.4. The impurity Ⅰ-Ⅴ detection limit (S/N = 3) was 0.17, 0.10, 0.06, 0.15, 0.10 μg·mL-1, respectively. Good linear relationship was established between the peak response and the concentration in the range of 0.48-51.30 μg·mL-1 for all impurities. The spiked recovery of impurity Ⅰ-Ⅴ was found to be acceptable for 99.9%, 98.9%, 102.1%, 100.1%, 96.3% (

ObjectiveThis study aimed to observe the impact of sinomenine hydrochloride on the proliferation of fibroblasts and the mRNA expression of related genes in knee joint adhesion and contracture in rabbits. Additionally, we sought to explore its potential mechanisms in combating knee joint adhesion and contracture. MethodsFibroblasts were cultured in vitro, and experimental groups with varying concentrations of sinomenine hydrochloride were established alongside a control group. Cell proliferation was assessed using the CCK-8 assay. Changes in the mRNA expression of fibroblast-related genes following sinomenine hydrochloride treatment were evaluated using RT-qPCR. The impact of the drug on serum levels of inflammatory cytokines was determined using the ELISA method, and the expression of related proteins was assessed using Western blot. ResultsSinomenine hydrochloride was found to inhibit fibroblast viability, with viability decreasing as the concentration of sinomenine hydrochloride increased. The effects of sinomenine hydrochloride in all experimental groups were highly significant (P<0.05). At the mRNA expression level, compared to the control group, sinomenine hydrochloride led to a significant downregulation of inflammatory cytokines in all groups (P<0.05). Additionally, the expression levels of apoptosis-related proteins significantly increased, while Bcl-2 mRNA expression decreased (P<0.05). The mRNA expression levels of the PI3K/mTOR/AKT3 signaling pathway also decreased (P<0.05). At the protein expression level, in comparison to the control group, the levels of inflammatory cytokines IL-6, IL-8, IL-1β, and TGF-β were significantly downregulated in the middle and high-dose sinomenine hydrochloride groups (P<0.05). The expression levels of cleaved-PARP, cleaved caspase-3/7, and Bax increased and were positively correlated with the dose, while the expression levels of the anti-apoptotic protein Bcl-2 and the PI3K/AKT3/mTOR signaling pathway were negatively correlated with the dose. Sinomenine hydrochloride exhibited a significant inhibitory effect on the viability of rabbit knee joint fibroblasts, which may be associated with the downregulation of inflammatory cytokines IL-6, IL-8, and IL-1β, promotion of apoptosis-related proteins cleaved-PARP, cleaved caspase-3/7, and Bax, suppression of Bcl-2 expression, and inhibition of gene expression in the downstream PI3K/AKT3/mTOR signaling pathway. ConclusionSinomenine hydrochloride can inhibit the inflammatory response of fibroblasts in adhesive knee joints and accelerate fibroblast apoptosis. This mechanism may offer a novel approach to improving and treating knee joint adhesion.

Objective:To discuss the possibility of modifying nonfunctional distractors to improve the quality of multiple-choice questions in medical examination through analyzing the changes in the difficulty and discrimination of items and the selection rate of modified distractors.Methods:Thirty-two multiple-choice questions involving nonfunctional distractors from a medical examination were studied. According to the item-writing guidelines, experts modified nonfunctional distractors based on actual measurements. We analyzed the changes in the difficulty and discrimination of items and the selection rate of modified distractors before and after item modification using the paired Wilcoxon test, and investigated the correlation of item difficulty and discrimination before and after item modification by Spearman's rank correlation analysis.Results:Six questions were modified due to technical factors, and 26 questions were modified due to weak interference in knowledge content. Before and after nonfunctional distractor modification, the difficulty values of the questions were 0.676 (0.558, 0.893) and 0.637 (0.531, 0.839), respectively; the discrimination values (point-biserial correlation) were 0.261 (0.150, 0.316) and 0.262 (0.138, 0.358), respectively; and the discrimination index values were 0.215 (0.113, 0.352) and 0.259 (0.138, 0.346), respectively. There were significant differences in the difficulty and discrimination index of items before and after modification. The difficulty and discrimination of items before and after modification were both significantly correlated. The selection rates of modified distractors were 0.009 (0.003, 0.015) and 0.044 (0.021, 0.092) before and after modification, respectively, which were significantly different.Conclusions:Nonfunctional distractors in this study were mainly caused by reasons in the contents of the test questions, less in technical defects. Through the analysis and modification of nonfunctional distractors, the selection rate of nonfunctional distractors can be effectively increased, and item difficulty and discrimination can be improved.
