Clinical practice guidelines represent the best recommendations for patient care. They are developed through systematically reviewing currently available clinical evidence and weighing the relative benefits and risks of various interventions. However, clinical practice guidelines have to go through a long translation cycle from development and revision to clinical promotion and application, facing problems such as scattered distribution, high duplication rate, and low actual utilization. At present, the clinical practice guideline information platform can directly or indirectly solve the problems related to the lengthy revision cycles, decentralized dissemination and limited application of clinical practice guidelines. Therefore, this paper systematically examines different types of clinical practice guideline information platforms and investigates their corresponding challenges and emerging trends in platform design, data integration, and practical implementation, with the aim of clarifying the current status of this field and providing valuable reference for future research on clinical practice guideline information platforms.

T7 RNA polymerase (T7 RNAP) is one of the simplest known RNA polymerases. Its unique structural features make it a critical model for studying the mechanisms of RNA synthesis. This review systematically examines the static crystal structure of T7 RNAP, beginning with an in-depth examination of its characteristic “thumb”, “palm”, and “finger” domains, which form the classic “right-hand-like” architecture. By detailing these structural elements, this review establishes a foundation for understanding the overall organization of T7 RNAP. This review systematically maps the functional roles of secondary structural elements and their subdomains in transcriptional catalysis, progressively elucidating the fundamental relationships between structure and function. Further, the intrinsic flexibility of T7 RNAP and its applications in research are also discussed. Additionally, the review presents the structural diagrams of the enzyme at different stages of the transcription process, and through these diagrams, it provides a detailed description of the complete transcription process of T7 RNAP. By integrating structural dynamics and kinetics analyses, the review constructs a comprehensive framework that bridges static structure to dynamic processes. Despite its advantages, T7 RNAP has a notable limitation: it generates double-stranded RNA (dsRNA) as a byproduct. The presence of dsRNA not only compromises the purity of mRNA products but also elicits nonspecific immune responses, which pose significant challenges for biotechnological and therapeutic applications. The review provides a detailed exploration of the mechanisms underlying dsRNA formation during T7 RNAP catalysis, reviews current strategies to mitigate this issue, and highlights recent progress in the field. A key focus is the semi-rational design of T7 RNAP mutants engineered to minimize dsRNA generation and enhance catalytic performance. Beyond its role in transcription, T7 RNAP exhibits rapid development and extensive application in fields, including gene editing, biosensing, and mRNA vaccines. This review systematically examines the structure-function relationships of T7 RNAP, elucidates the mechanisms of dsRNA formation, and discusses engineering strategies to optimize its performance. It further explores the engineering optimization and functional expansion of T7 RNAP. Furthermore, this review also addresses the pressing issues that currently need resolution, discusses the major challenges in the practical application of T7 RNAP, and provides an outlook on potential future research directions. In summary, this review provides a comprehensive analysis of T7 RNAP, ranging from its structural architecture to cutting-edge applications. We systematically examine: (1) the characteristic right-hand domains (thumb, palm, fingers) that define its minimalistic structure; (2) the structure-function relationships underlying transcriptional catalysis; and (3) the dynamic transitions during the complete transcription cycle. While highlighting T7 RNAP’s versatility in gene editing, biosensing, and mRNA vaccine production, we critically address its major limitation—dsRNA byproduct formation—and evaluate engineering solutions including semi-rationally designed mutants. By synthesizing current knowledge and identifying key challenges, this work aims to provide novel insights for the development and application of T7 RNAP and to foster further thought and progress in related fields.

Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.

Licorice-gypsum (gancao-shigao, GC-SG) drug pair was used as the research object, using supramolecular chemistry to explore the scientific connotation of combining herbal medicine GC with insoluble mineral medicine SG in clinical application of traditional Chinese medicine. ① The Tyndall effect, microscopic morphology and particle size of the single and co-decocted of GC and SG were observed, the paste content and conductivity were determined, and the interaction between GC and SG was detected by isothermal titration calorimetry (ITC) and infrared absorption spectroscopy (IR). ② Calcium chloride (CaCl₂), a soluble calcium salt of equal gypsum quality, was used instead of SG with GC for co-decocting to explore the effect of calcium salt content on the water decocting, and the characteristics were combined with the Tyndall effect, microscopic morphology, paste content and conductivity. ITC and IR techniques were used to detect the interaction between the two, and the interaction between them was detected by ITC and IR. The zeta potential and ultraviolet-visible spectrophotometry (UV-vis) of GC-SG and GC-CaCl₂ co-decoction were compared, and the inorganic and organic components in the co-decoction were detected by inductively coupled plasma optical emission spectrometer (ICP-OES) and high performance liquid chromatography (HPLC). The results showed: ① Compared with the liquid phase of single decoction, GC-SG co-decoction had more obvious Tyndall effect, and showed uniform spherical nanoparticles under electron microscope. Physical characterization results such as paste content and conductivity showed that co-decoction promoted the dissolution of each other's components; ITC and IR results showed that there was strong interaction between GC and SG, which preliminatively indicated that GC and SG co-decoction promoted the formation of uniform and stable supramolecular system of traditional Chinese medicine. ② When soluble calcium salt was used to substitute insoluble SG with GC for co-decocting, a stronger but astigmatic light path appeared than single decocting solution, the zeta potential was reduced, and a large number of accumulated polymers were formed. The results of paste content and conductivity showed that the dissolution of the co-decocting component was reduced than the single decocting component. ITC, UV-vis and IR results showed that there was interaction between GC with Ca²⁺ and SG. The formation of polysink indicated that a large amount of soluble calcium salt would destroy the stability of supramolecular Chinese medicine. The results of ICP-OES and HPLC showed that the glycyrrhizic acid (GA) content of the former lower than the latter, which was related to the formation of a large number of polycondensates with the increase of Ca²⁺ concentration and the decrease of the dissolution of GA and other active ingredients. This study indicates that the compatibility of GC and SG can form a uniform and stable supramolecular system of traditional Chinese medicine. Calcium salt, the main component of SG, is taken as the starting point. Excessive soluble Ca²⁺ can promote the aggregation of active ingredients such as GA, so as to reveal the scientific connotation of the compatibility of GC and SG, an insoluble mineral medicine.

The effect of different concentrations of glycyrrhizic acid (GA) and Zn²⁺ on the self-assembly of metal complexes was investigated by forming metal complexes, and the properties and assembly mechanisms of the formed carrier-free supramolecular hydrogel were characterised. Scanning electron microscopy (SEM) and zeta potential were used to characterise the microscopic morphology and stability of the GA-Zn complex hydrogel, which had spherical-like particles of about 1 μm with good stability; the rheometer was used to detect its materialistic properties, which showed excellent stability, self-healing property and reversibility; through in vitro bacterial inhibition, it was found that the GA-Zn carrier-free supramolecular hydrogel has enhanced bacterial inhibition function after assembly. The hydrogel was also found to possess both anti-inflammatory and antioxidant efficacy when evaluated using LPS and H₂O₂ induced RAW 264.7 cell damage models, respectively. The above results suggest that GA-Zn hydrogel not only has good materialistic properties, but also possesses good antibacterial, anti-inflammatory and antioxidant activities, which has the value of clinical research as a carrier-free multi-functional antimicrobial dressing, and the present study provides a reference for the discovery of novel biomedical materials from active molecules of natural traditional Chinese medicine.

Based on the interaction between supramolecule of traditional Chinese medicine and enterobacteria, the material basis of Rhei Radix et Rhizoma and Coptidis Rhizoma was explored. Scanning electron microscopy (SEM) and dynamic light scattering (DLS) were used to characterize the morphological differences of Rhubarb single decoction, Coptis single decoction and Rhubarb and Coptis co-decoction. An in vitro antibacterial model (E. coli, E. faecium and B. subtilis) was established to evaluate the damage effect of the combination of Rhei Radix et Rhizoma and Coptidis Rhizoma on enterobacteria. Ultra high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was used to analyze the changes of chemical components of single decoctions and co-decoctions. The co-decoction of Rhei Radix et Rhizoma and Coptidis Rhizoma was turbid after decocting. The spherical particles of 300-400 nm were observed under SEM, and the co-decoction was more uniform and stable than that of single decoction. The interaction between supramolecules formed after the combination of Rhei Radix et Rhizoma and Coptidis Rhizoma and enterobacteria was significantly different from that of single decoction. In the process of interaction between supramolecules and enterobacteria, the spherical state was maintained, and the medicinal ingredients in Coptidis Rhizoma or Rhei Radix et Rhizoma were blocked, which could effectively alleviate the damage to enterobacteria. This study provided a reference for subsequent studies on the regulation of intestinal flora homeostasis by the combination of Rhei Radix et Rhizoma and Coptidis Rhizoma.

OBJECTIVE To establish HPLC fingerprint of Shuangdong capsules， and to study the spectral effect relationship of its anti-inflammatory effect. METHODS The fingerprints of 15 batches of Shuangdong capsules were established by HPLC，and the similarity evaluation was carried out； the foot swelling model was established to investigate the anti-inflammatory activity of Shuangdong capsules. The gray correlation analysis method was used to construct the spectral effect relationship for the anti- inflammatory effect of Shuangdong capsules using the swelling rate of rat foot and the levels of malondialdehyde （MDA）， superoxide dismutase （SOD）， prostaglandin E2 （PGE2）， interleukin-6 （IL-6）， IL-8， IL-1β and tumor necrosis factor-α （TNF-α） in right hindfoot tissues as the pharmacodynamic indexes of anti-inflammatory effects. RESULTS Overall 15 batches of Shuangdong capsules identified 20 common peaks， the similarities were all greater than 0.97， and a total of 8 chromatographic peaks were identified. According to the gray correlation analysis， the correlation degrees between the peak area and the foot swelling rate and the levels of MDA， SOD， PGE2， IL-6， IL-8， IL-1β and TNF-α in 15 batches of Shuangdong capsules were 0.621 1- 0.783 5， 0.564 3-0.827 9， 0.581 0-0.845 3， 0.564 9-0.855 0， 0.583 1-0.856 4， 0.576 5-0.863 5， 0.564 1-0.838 0 and 0.572 5- 0.851 3， respectively. Among them， the chemical components represented by peak 4 （geniposidic acid）， peak 10 （chlorogenic acid） and the chemical composition represented by peak 2 were strongly correlated with anti-inflammatory efficacy indicators. CONCLUSIONS In this study， HPLC fingerprints of 15 batches of Shuangdong capsules were successfully established. Among them， geniposidic acid， chlorogenic acid may be its anti-inflammatory ingredients.

ObjectiveTemporal heterogeneity in lung cancer presents as fluctuations in the biological characteristics, genomic mutations, proliferation rates, and chemotherapeutic responses of tumor cells over time, posing a significant barrier to effective treatment. The complexity of this temporal variance, coupled with the spatial diversity of lung cancer, presents formidable challenges for research. This article will pave the way for new avenues in lung cancer research, aiding in a deeper understanding of the temporal heterogeneity of lung cancer, thereby enhancing the cure rate for lung cancer. MethodsRaman spectroscopy emerges as a powerful tool for real-time surveillance of biomolecular composition changes in lung cancer at the cellular scale, thus shedding light on the disease’s temporal heterogeneity. In our investigation, we harnessed Raman spectroscopic microscopy alongside multivariate statistical analysis to scrutinize the biomolecular alterations in human lung epithelial cells across various timeframes after benzo(a)pyrene exposure. ResultsOur findings indicated a temporal reduction in nucleic acids, lipids, proteins, and carotenoids, coinciding with a rise in glucose concentration. These patterns suggest that benzo(a)pyrene induces structural damage to the genetic material, accelerates lipid peroxidation, disrupts protein metabolism, curtails carotenoid production, and alters glucose metabolic pathways. Employing Raman spectroscopy enabled us to monitor the biomolecular dynamics within lung cancer cells in a real-time, non-invasive, and non-destructive manner, facilitating the elucidation of pivotal molecular features. ConclusionThis research enhances the comprehension of lung cancer progression and supports the development of personalized therapeutic approaches, which may improve the clinical outcomes for patients.
