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.

AIM: To analyze the prevalence, severity, types, and correction of astigmatism in children, and provide scientific evidences for the prevention and treatment of refractive errors.METHODS: This cross-sectional study included 29 153 children aged 6-12 years from Xi'an and Lantian County, Shaanxi Province, China. Visual acuity and non-cycloplegic refraction were measured. Astigmatism was defined as an absolute cylindrical power ≥0.5 D in the right eye. Differences in astigmatism severity, type distribution, and refractive correction were analyzed across age, gender, and region.RESULTS:The prevalence of astigmatism increased with age, peaking at 11 years old(62.88%). Boys(57.10%)had a higher prevalence than girls(54.86%), and the municipal areas(58.29%)had a higher prevalence than county areas(51.75%). Mild astigmatism was the most common(63.82%), with moderate astigmatism increasing with age. The highest prevalence of high astigmatism was observed in 11-years-old children(9.68%). Compound myopic astigmatism(59.28%)and mixed astigmatism(25.16%)were the most frequent types. With increasing age, compound myopic astigmatism increased, while simple myopic, simple hyperopic, and compound hyperopic astigmatism decreased. Mixed astigmatism increased from ages 6 to 7, but declined from ages 7 to 12. For astigmatic axis types, with-the-rule astigmatism was the most prevalent(81.06%)and increased with age, peaking at 11 years(85.74%). Against-the-rule astigmatism showed a declining trend, while oblique astigmatism remained relatively stable. Distribution differences in astigmatism types and axes by gender and region were observed. Significant differences in astigmatism severity, types, and axis types across different ages, genders, and regions were observed(all P<0.05). The overall refractive correction rate for children with astigmatism was only 40.18%.CONCLUSION: The overall prevalence of astigmatism among children aged 6-12 years in Shaanxi Province was 56.02%, with higher prevalence observed in boys and in municipal areas. Age, gender, and region significantly influenced the prevalence of astigmatism. Notably, less than half of the children with astigmatism received refractive correction, highlighting the need for increased attention from parents and relevant authorities.

OBJECTIVE To investigate the efficacy and safety of ropivacaine combined with oxycodone for the analgesia of iliac fascia nerve block in patients undergoing hip replacement. METHODS Sixty-six patients who underwent hip replacement at the Central Hospital of Enshi Tujia and Miao Autonomous Prefecture from October 2023 to April 2024 were selected and randomly divided into observation group and control group, with 33 cases in each group. Before induction of anesthesia, ultrasound-guided iliac fascial nerve block was performed. Patients in the observation group were treated with 0.33% ropivacaine+0.1 mg/kg oxycodone injection mixture 30 mL, and patients in the control group were treated with 0.33% ropivacaine injection 30 mL. The time of first postoperative rescue analgesia, 24 h postoperative analgesic drug consumption, sensory block and motor block effective and maintenance time, satisfaction degree, numerical rating scale (NRS) pain score, Ramsay sedation score, muscle strength score, heart rate (HR), mean arterial pressure (MAP), oxygen saturation(SpO2), sleep score, anxiety score, and the occurrence of adverse reactions in the two groups were all recorded. RESULTS Compared with the control group, the first rescue analgesia time after operation was significantly prolonged in the observation group, and 24 h postoperative analgesic drug consumption after operation decreased; the effective time of sensory block was significantly shortened, and the maintenance time of sensory block was significantly prolonged, and the satisfaction score was higher; the NRS pain score after iliac fascia nerve block was lower, HR and MAP were lower, and the anxiety score and sleep score 24 and 48 h after operation were lower (P<0.05). In terms of safety, patients in both groups had adverse reactions after operation, such as hypertension, nausea, vomiting, and dizziness, but there was no significant difference in the incidence of adverse reactions between the two groups (P>0.05). CONCLUSIONS Oxycodone combined with ropivacaine shows good efficacy and safety for iliac fascial nerve block analgesia in patients undergoing hip replacement, can significantly prolong the analgesic time of ropivacaine, reduce postoperative analgesic drug consumption, improve the sleep quality of patients, and promote the rapid recovery of patients.

ObjectiveThe rapid advancement of bioanalytical technologies has heightened the demand for high-throughput, label-free, and real-time cellular analysis. Electrochemical impedance spectroscopy (EIS) operating in the GHz frequency range (GHz-EIS) has emerged as a promising tool for characterizing cell suspensions due to its ability to rapidly and non-invasively capture the dielectric properties of cells and their microenvironment. Although GHz-EIS enables rapid and label-free detection of cell suspensions, significant challenges remain in interpreting GHz impedance data for complex samples, limiting the broader application of this technique in cellular research. To address these challenges, this study presents a novel method that integrates GHz-EIS with deep learning algorithms, aiming to improve the precision of cell suspension concentration identification and quantification. This method provides a more efficient and accurate solution for the analysis of GHz impedance data. MethodsThe proposed method comprises two key components: dielectric property dataset construction and backpropagation (BP) neural network modeling. Yeast cell suspensions at varying concentrations were prepared and separately introduced into a coaxial sensor for impedance measurement. The dielectric properties of these suspensions were extracted using a GHz-EIS dielectric property extraction method applied to the measured impedance data. A dielectric properties dataset incorporating concentration labels was subsequently established and divided into training and testing subsets. A BP neural network model employing specific activation functions (ReLU and Leaky ReLU) was then designed. The model was trained and tested using the constructed dataset, and optimal model parameters were obtained through this process. This BP neural network enables automated extraction and analytical processing of dielectric properties, facilitating precise recognition of cell suspension concentrations through data-driven training. ResultsThrough comparative analysis with conventional centrifugal methods, the recognized concentration values of cell suspensions showed high consistency, with relative errors consistently below 5%. Notably, high-concentration samples exhibited even smaller deviations, further validating the precision and reliability of the proposed methodology. To benchmark the recognition performance against different algorithms, two typical approaches—support vector machines (SVM) and K-nearest neighbor (KNN)—were selected for comparison. The proposed method demonstrated superior performance in quantifying cell concentrations. Specifically, the BP neural network achieved a mean absolute percentage error (MAPE) of 2.06% and an R² value of 0.997 across the entire concentration range, demonstrating both high predictive accuracy and excellent model fit. ConclusionThis study demonstrates that the proposed method enables accurate and rapid determination of unknown sample concentrations. By combining GHz-EIS with BP neural network algorithms, efficient identification of cell concentrations is achieved, laying the foundation for the development of a convenient online cell analysis platform and showing significant application prospects. Compared to typical recognition approaches, the proposed method exhibits superior capabilities in recognizing cell suspension concentrations. Furthermore, this methodology not only accelerates research in cell biology and precision medicine but also paves the way for future EIS biosensors capable of intelligent, adaptive analysis in dynamic biological research.

This article systematically analyzes the historical evolution of the name, origin, medicinal parts, harvesting and processing, and other aspects of Manjiao and Zanthoxyli Radix by referring to the herbal medicine, medical books, prescription books and other documents of the past dynasties, combined with the relevant modern research materials, in order to provide a basis for the development of famous classical formulas containing the two medicinal materials. According to the herbal textual research, Manjiao was first recorded in Shennong Bencaojing of the Han dynasty with aliases such as Zhujiao, Goujiao and Zhijiao. Throughout history, Manjiao was sourced from the stems and roots of Zanthoxylum armatum in the Rutaceae family, and its leaves and fruits can also be used in medicine. The traditional recorded production area was mainly in Yunzhong(now Tuoketuo region in Inner Mongolia), with mentions in Zhejiang, Hunan, Fujian, Guangdong, Guangxi, Yunnan, Taiwan, and other provinces. Presently, this species is distributed from the south of Shandong, to Hainan, Taiwan, Tibet and other regions. The roots can be harvested year-round, while the fruits are harvested in autumn after maturity. In ancient times, the roots and stems were mostly used for brewing or soaking in wine, whereas nowadays, the roots are often sliced and then used as a raw material in traditional Chinese medicine, and the fruits should be stir-fried before use. Manjiao has a bitter taste and warm property, and was historically used to treat wind-cold dampness, joint pain, limb numbness, and knee pain. Modern researches have summarized its effects as dispelling wind, dispersing cold, promoting circulation, and relieving pain, and it is used for treating rheumatoid arthritis, toothache, bruises, as well as an anthelmintic. Zanthoxyli Radix initially known as Rudi Jinniugen, recorded in Bencao Qiuyuan of the Qing dynasty, with the alternate name of Liangbianzhen. In recent times, it is more commonly referred to as Liangmianzhen, sourced from the dried roots of Z. nitidum of the Rutaceae family, mainly produced in Guangxi and Guangdong. It can be harvested throughout the year, cleaned, sliced, and dried after harvesting. Zanthoxyli Radix is pungent, bitter, warm and slightly toxic, with the functions of promoting blood circulation, removing stasis, relieving pain, dispelling wind, and resolving swelling. Based on the results of herbal textual research, it is clarified that the ancient Manjiao and the modern Zanthoxyli Radix are not the same species. This article corrects the mistaken belief of by previous scholars that Zanthoxyli Radix is the same as ancient Manjiao, and suggests that formulas described as Manjiao should use Z. armatum as the medicinal herb, while those described as Liangmianzhen or Rudi Jinniu should use Z. nitidum. The processing was performed according to the processing requirements prescribed in the formulas, otherwise, the raw products are recommended for use.

Objective:
This study aims to evaluate the clinical benefits of the integrated optical and magnetic surgical navigation system in assisting transforaminal endoscopic lumbar discectomy (TELD) for the treatment of lumbar disc herniation (LDH).
Methods:
A retrospective analysis was conducted on patients who underwent TELD for LDH at Beijing Chaoyang Hospital, Capital Medical University from November 2022 to December 2023. Patients treated with the integrated optical and magnetic surgical navigation system were defined as the navigation-guided TELD (Ng-TELD) group (30 cases), while those treated with the conventional x-ray fluoroscopy method were defined as the control group (31 cases). Record and compare baseline characteristics, surgical parameters, efficacy indicators, and adverse events between the 2 patient groups.
Results:
The average follow-up duration for the 61 patients was 11.8 months. Postoperatively, both groups exhibited significant relief from back and leg pain, which continued to improve over time. At the final follow-up, patients’ lumbar function and quality of life had significantly improved compared to preoperative levels (p < 0.05). The Ng-TELD group had significantly shorter total operation time (58.43 ± 12.37 minutes vs. 83.23 ± 25.90 minutes), catheter placement time (5.83 ± 1.09 minutes vs. 15.94 ± 3.00 minutes), decompression time (47.17 ± 11.98 minutes vs. 67.29 ± 24.23 minutes), and fewer intraoperative fluoroscopies (3.20 ± 1.45 vs. 16.58 ± 4.25) compared to the control group (p < 0.05). There were no significant differences between the groups in terms of efficacy evaluation indicators and hospital stay. At the final follow-up, the excellent and good rate of surgical outcomes assessed by the MacNab criteria was 98.4%, and the overall adverse event rate was 8.2%, with no statistically significant differences between the groups (p > 0.05).
Conclusion
This study demonstrates that the integrated optical and magnetic surgical navigation system can reduce the complexity of TELD, shorten operation time, and minimize radiation exposure for the surgeon, highlighting its promising clinical potential.

BACKGROUND:Previous studies by our research group discovered that Jiawei Xiaoyao San has a significant anti-liver cancer effect,but the specific mechanism of action was unclear. OBJECTIVE:To investigate the regulatory effects of the traditional Chinese medicine formula Jiawei Xiaoyao San on the levels of miRNAs in plasma exosomes of rats with diethylnitrosamine chronically induced primary liver cancer,based on high-throughput sequencing combined with bioinformatics. METHODS:SD rats were randomly divided into a blank control group,a liver cancer model group,and a Jiawei Xiaoyao San treatment group.Liver cancer models were induced by continuous administration of diethylnitrosamine for 12 weeks.Starting from the 17th week,rats in the Jiawei Xiaoyao San treatment group were administered Jiawei Xiaoyao San once daily until the end of the 20th week,while rats in the blank control and liver cancer model groups were given an equivalent volume of saline.Anti-hepatocellular carcinoma effects were validated by assessing the morphological structure of rat liver tissues,along with the expression of the hepatocellular carcinoma markers,Glypican-3 protein and serum alpha-fetoprotein.Plasma exosomes from each group of rats were isolated using ultracentrifugation.High-throughput sequencing technology was used to screen for differentially expressed miRNAs in rat plasma exosomes.Bioinformatics was used to predict the potential biomarkers through which Jiawei Xiaoyao San exerts its anti-liver cancer effects via liver cancer-derived exosomal miRNAs,followed by functional analysis. RESULTS AND CONCLUSION:(1)Jiawei Xiaoyao San significantly improved the morphological structure of liver tissues in a rat model of liver cancer.Compared with the liver cancer model group,the expression of liver cancer markers Glypican-3 protein and serum alpha-fetoprotein was significantly reduced in the Jiawei Xiaoyao San treatment group.(2)Bioinformatics analysis showed that in the Jiawei Xiaoyao San group,upregulated miR-223-3p in the liver cancer model group had target binding sites with genes E2F1 and NCOA1,which were closely related to liver cancer survival and prognosis.Therefore,Jiawei Xiaoyao San has a therapeutic effect on liver cancer,possibly by targeting negative regulation of NCOA1/E2F1 through liver cancer plasma-derived exosomal miR-223-3p,thereby playing anti-liver cancer effect.
