Sangjuyin, as a pungent and cooling agent with precise therapeutic effect, is a classic pungent formula for cooling relief of the epidermis, which is highly respected by medical practitioners. This formula is from the Wenbing Tiaobian written by WU Jutong in the Qing dynasty, on the basis of which subsequent medical practitioners have made additions and subtractions to apply it. The authors used the bibliometric method to systematically organize the medical books from the Qing dynasty and the Republic of China and modern literature to analyze the composition, concoction, decoction, efficacy, and previous and modern application of Sangjuyin. After examination, the drug base of this formula is basically clear. Armeniacae Semen Amarum is the dried mature seeds of Armeniaca vulgaris, family Rosaceae. Forsythiae Fructus is the dried fruit of Forsythia suspensa, family Mulleinaceae. Menthae Haplocalycis Herba is the dried above-ground part of Mentha haplocalyx, family Labiatae. Mori Folium is the dried leaves of Morus alba, family Moraceae. Chrysanthemi Flos is the dried head of Chrysanthemum morifolium, family Asteraceae. Platycodonis Radix is the dried root of Eryngium grandiflorum, family Eryngium. Glycyrrhizae Radix et Rhizoma is the dried root and rhizome of Glycyrrhiza uralensis of the Leguminosae family, and Phragmitis Rhizoma is the fresh or dried rhizome of Phragmites communis of the Gramineae family. It is recommended that the eight drugs be used in raw form as medicine. The dosage and method of decoction were converted into a modern single dosage of 7.46 g Armeniacae Semen Amarum, 5.60 g Forsythiae Fructus, 2.98 g Menthae Haplocalycis Herba, 9.33 g Mori Folium, 3.73 g Chrysanthemi Flos, 7.46 g Platycodonis Radix, 2.98 g Glycyrrhizae Radix et Rhizoma, and 11.19 g Phragmitis Rhizoma, with 400 mL water added, and the solution was boiled to obtain 200 mL, taken twice a day. Sangjuyin has the efficacy of dispersing wind and clearing heat, promoting lung and relieving cough, and it is used for treating the initial onset of wind-warmth and the evidence of evil spirits in the lungs and collaterals. Modern research has shown that Sangjuyin is often used in the treatment of cough, pneumonia, rhinitis, and other respiratory diseases, and the results of this study provide a reference for the later development of Sangjuyin.

OBJECTIVE To study the ameliorative effect and mechanism of Forsythia suspensa-Lonicera japonica herb pair on acute lung injury (ALI) based on serum exosomal microRNA (miRNA). METHODS The rats were randomly divided into a blank group (normal saline), model group (nomal saline), and F. suspensa-L. japonica herb pair group (2.55 g/kg), with 10 rats in each group. Except for the blank group, the other groups were used to establish an ALI model by intratracheal dripping of 5 mg/ mL lipopolysaccharides. After modeling, each group was given relevant medicine/normal saline intragastrically, once a day, for 3 consecutive days. After the last medication, the pathological status of lung tissue was observed; lung wet-to-dry weight ratio and leukocyte counts in bronchoalveolar lavage fluid (BALF) were determined. The levels of inflammatory factors [tumor necrosis factor-α(TNF-α), interleukin-1β (IL-1β), IL-10] in BALF were determined. Exosomes were isolated from rat serum, and high- throughput sequencing technology was employed to screen differentially expressed miRNA within the exosomes, followed by Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Based on the screened differentially expressed miRNA and the enriched KEGG pathways, in vitro cellular experiments were conducted for validation. RESULTS The animal experimental results demonstrated that after intervention with the F. suspensa-L. japonica herb pair, the wet-to-dry weight ratio, the number of leukocytes in BALF, as well as the levels of TNF-α and IL-1β in BALF of ALI rats were all significantly reduced (P<0.01), while the level of IL-10 was significantly increased (P<0.01). The results of high-throughput sequencing experiments revealed that the F. suspensa-L. japonica herb pair could significantly up-regulate the expressions of miR-345-3p, miR-194-5p, miR-653-5p, and others in exosomes. Among them, the KEGG pathways involved in the target genes of differentially expressed miRNA included the hypoxia-inducible factor-1(HIF-1) signaling pathway, among others. The results of cellular E-mail:huang.haiying@126.com validation experiments showed that overexpressed miR-345-3p could significantly elevate the level of IL-10 in the cell supernatant (P<0.01), while significantly reducing the levels of TNF-α and IL-1β in the cell supernatant, as well as the mRNA and protein expression levels of protein kinase B1, phosphatidylinositol 3- kinase, and HIF-1α (P<0.01). CONCLUSIONS F. suspensa-L. japonica herb pair can alleviate inflammatory responses and thereby exert a therapeutic effect in improving ALI by up-regulating the expression of miR-345-3p in serum exosomes and inhibiting the activity of the HIF-1 signaling pathway.
3.Strategies and Challenges of Hydrogen Production Catalyzed by Bioencapsulated Hydrogenase
Progress in Biochemistry and Biophysics 2026;53(5):1415-1438
Hydrogenases, as a class of highly efficient and reversible biological catalysts, can catalyze the reduction of protons to molecular hydrogen, thus demonstrating great potential in a wide range of fields such as renewable energy production and green chemistry. Despite their significant potential, the large-scale industrial application of hydrogenases has long been constrained by several inherent limitations, including high sensitivity to molecular oxygen, the challenges in the in vitro reconstitution and maturation of their catalytic centers, and the inefficiency and instability of the natural electron transfer pathways. To overcome these limitations and enhance the catalytic performance of hydrogenases, researchers have developed various strategies, among which enzyme molecular engineering, photo-driven modification, and enzyme immobilization techniques are the most common exploration directions. Particularly, enzyme immobilization technology is widely used to improve the reusability of hydrogenases, but traditional immobilization methods often come with disadvantages in practical applications, such as complex multi-step procedures and insufficient biocompatibility of the immobilization materials. In recent years, bioencapsulation technology has emerged as a promising alternative strategy to enhance the catalytic performance of hydrogenases. This method utilizes biologically derived encapsulation materials to construct physically confined and precisely defined chemical microenvironments around the enzyme molecules, offering simpler self-assembly processes and superior biocompatibility. With these biomimetic constructs, bioencapsulation technology not only provides better oxygen tolerance but also helps to create a local microenvironment conducive to sustained catalytic function. This article systematically reviews the latest research progress of two main bioencapsulation strategies for hydrogenases: one is the encapsulation technology based on protein-based nanocages; the other is the engineering strategy for whole-cell hydrogenase expression. In the nanocage-based systems, this article focuses on the structural and functional characteristics of virus-like capsids and carboxysome protein shells, which serve as efficient enzyme encapsulation scaffolds, not only providing a stable physical barrier to prevent oxygen diffusion but also enabling high-density enzyme loading, thereby promoting substrate channeling effects and electron transfer kinetics. This article also discusses whole-cell encapsulation systems, which achieve hydrogenase compartmentalization within engineered cellular structures or by using external natural polysaccharide-based encapsulation matrices to wrap whole-cell catalysts. Bioencapsulation strategies can bring multiple synergistic benefits: they can effectively protect hydrogenases from oxygen-mediated inactivation, significantly delay the decline of catalytic activity over time, and enhance the hydrogen production rate by increasing the local concentration of active enzyme molecules and optimizing the electron transfer efficiency from redox partners to the catalytic center.Despite the significant progress made, several technical challenges remain to be addressed. The main obstacles include limited enzyme loading and encapsulation efficiency, insufficient long-term stability of encapsulation materials under operating conditions, and the need to improve the matching of the photo-biological interface in systems integrating light-harvesting components with enzymatic catalysis. Future efforts can focus on the integration of multiple technological approaches, such as using computer-aided protein design to optimize encapsulation structures, developing engineered electron transfer pathways to enhance catalytic conversion efficiency, and designing composite multifunctional materials with both structural stability and functional adaptability. These directions collectively aim to achieve efficient, stable, and scalable hydrogen production applications of bioencapsulated hydrogenase systems.

Background/Aims:
Non-pharmacological treatments are crucial for managing irritable bowel syndrome (IBS), yet patient engagement remains a challenge. Understanding patients' knowledge, attitudes, and practices regarding these treatments is essential for improving care.
Methods:
A cross-sectional study was conducted across 5 hospitals, from October 2023 to February 2024. A self-designed knowledge, attitudes, and practices questionnaire along with the IBS quality of life and IBS severity scoring system was administered, and 496 valid responses were analyzed. Statistical analyses included correlation tests, multivariate linear regression, and mediation effect analysis.
Results:
The median scores for knowledge, attitude, and practice were 28, 25.5, and 21, respectively. Significant positive correlations were found between knowledge-attitude (r = 0.195), knowledge-practice (r = 0.364), and attitude-practice (r = 0.151). The multivariate linear regression analysis further indicated that knowledge (β = 0.399, P < 0.001) and attitude (β = 0.219, P = 0.022) positively correlated with the practical performance. SEM revealed that knowledge had a significant direct effect on both attitude (β = 0.186, P = 0.013) and practice (β = 0.356, P = 0.006). However, the direct effect of attitude on practice was not significant, and attitude did not mediate the relationship between knowledge and practice.
Conclusions
IBS patients exhibit a significant gap between their positive attitudes and their actual practices concerning non-pharmacological treatments. Knowledge is a direct driver of practice, but positive attitudes alone are insufficient to translate into behavior. Healthcare providers must move beyond simply fostering positive attitudes and focus on targeted educational interventions that provide actionable knowledge and skills to improve patient outcomes.

OBJECTIVE To compare the predictive accuracy and clinical applicability of four vancomycin individualized dosing tools (SmartDose, ClinCalc, Gulou, Pharmado) and provide a basis for rational clinical medication use. METHODS A retrospective cohort study was conducted, enrolling 479 adult patients who received vancomycin therapy and underwent steady-state trough concentration monitoring in Zhongshan Hospital, Fudan University (Xiamen Branch) from January 1, 2022, to June 30, 2024. The predictive accuracy of each tool was evaluated using indicators, such as mean error (ME), mean absolute error (MAE), mean percentage error (MPE), mean absolute percentage error (MAPE), the proportion of patients with an absolute percentage error (APE) of less than 30%, the 95% limits of agreement, and the overall relative percentage difference between predicted and measured values. Using indicators such as accessibility, patient management, and recommendation of multiple treatment options, the clinical panxso@163.com applicability of the tools for all patients was evaluated; using the discrepancy in accuracy between the predicted and actual measured blood drug concentrations as an indicator, the clinical applicability was assessed for patients in different renal function subgroups (hyperfunction, normal, mild impairment, moderate impairment, and severe impairment). RESULTS In terms of accuracy, SmartDose demonstrated the best overall performance with an MAPE of 46.40% and a proportion of APE <30% (46.56%). Bland-Altman analysis indicated that SmartDose had the smallest overall relative percentage difference (-7.25%), although the 95% limits of agreement were broad for all tools, with differences between the upper and lower limits exceeding 200%. In terms of applicability, all four dosing tools were freely accessible and demonstrated good availability; SmartDose and Pharmado provided the most comprehensive solutions, offering features such as patient management, multiple regimen recommendations, and drug concentration-time curve plotting. Stratified analysis based on renal function revealed that Pharmado showed optimal prediction for hyperfiltration patients (mean difference: 0.11 mg/L). SmartDose and ClinCalc showed relatively better performance in normal and mild renal impaiment (mean difference: 0.37, 0.51 mg/L and -1.13, -1.33 mg/L,respectively). SmartDose performed best in moderate renal impairment (mean difference: -2.60 mg/L). Pharmado and Gulou had smaller prediction biases in severe renal impairment (mean differences: 1.52 mg/L and -0.23 mg/L, respectively). CONCLUSIONS The four individualized dosing tools demonstrated limited accuracy in the initial prediction of vancomycin concentrations. Among them, SmartDose demonstrates the highest overall prediction accuracy and possesses comprehensive clinical management features. It is recommended that Pharmado be preferred for patients with renal hyperfiltration; SmartDose or ClinCalc can be used for patients with normal or mildly impaired renal function; SmartDose is recommended for patients with moderately impaired renal function; Pharmado or Gulou may be considered for patients with severely impaired renal function.

Objective::To analyze fetal renal abnormality genetic features and the prenatal characteristics of the 17q12 microdeletion syndrome.Methods::This prospective cohort study examined prenatal ultrasound findings of renal abnormalities in pregnant women who underwent single nucleotide polymorphism (SNP) array or copy number variation sequencing (CNV-seq) testing on amniotic fluid or fetal tissue at Tianjin Central Obstetrics and Gynecology Hospital between January 2016 and August 2022. The study cohort comprised women with advanced maternal age, fetal ultrasound anomalies, high-risk non-invasive prenatal testing results, or suspected 17q12 microdeletion syndrome. Comprehensive clinical data, including maternal age, detailed ultrasound findings, and pregnancy outcomes, were systematically collected. SNP-array analysis was conducted using an Affymetrix CytoScan 750 K Array Chip to identify CNVs and loss of heterozygosity, while CNV-seq was performed on the Illumina HiSeq 2000 platform. Detected variants were classified according to the American College of Medical Genetics and Genomics guidelines. Statistical analyses were performed using SPSS version 27.0.Results::Abnormal renal development was identified in 141 patients, among whom 26 exhibited hyperechogenic kidneys (HCK). Of these, 12 cases were associated with 17q12 microdeletion syndrome, while the remaining 14 were linked to other chromosomal abnormalities. When excluding patients with HCK, those diagnosed with polycystic kidney disease demonstrated a higher prevalence of chromosomal abnormalities compared to those with multicystic dysplastic kidney and renal dysplasia. Although isolated conditions such as horseshoe kidney, hydronephrosis, ectopic kidney, and unilateral kidney typically presented with normal chromosomal findings, the incidence of chromosomal abnormalities increased when these conditions coexisted with other anomalies. A detailed analysis of the correlation between 17q12 microdeletion syndrome and HCK revealed that 12 out of the 14 patients diagnosed with 17q12 microdeletion syndrome exhibited HCK. Genetic testing confirmed the syndrome in seven patients, with five cases attributed to novel mutations and two cases resulting from inherited mutations.Conclusion::Fetal HCK was closely associated with the 17q12 microdeletion syndrome, and polycystic kidney disease showed a higher rate of chromosomal abnormalities. Chromosome test results were mostly normal in patients with other renal abnormalities, such as kidney dysplasia, horseshoe kidneys, hydronephrosis, kidney deficiency, and ectopic kidneys. Prenatal diagnosis is recommended, especially in cases of non-isolated fetal renal abnormalities. This study provides strong evidence supporting a link between fetal renal abnormalities and genetic syndromes.

Objective:To evaluate the value of ultrasound radiomics combined with machine learning for early diagnosis of seronegative Hashimoto’s thyroiditis (SN-HT) .Methods:This retrospective study included 164 patients from Liaoning Provincial People’s Hospital , Lixin County People’s Hospital, Linghai Dalinghe Hospital, Fengcheng Phoenix Hospital, who underwent thyroidectomy for solitary nodules with normal thyroid function between Nov. 2016 and Jan. 2024. Postoperative pathology confirmed Hashimoto’s thyroiditis (HT) in some cases, who were further categorized into antibody-positive and antibody-negative groups based on serum antibody status. Patients without Hashimoto’s thyroiditis served as the control group. A total of 298 ultrasound images were analyzed. Radiomics features were extracted from hypoechoic non-nodular areas within 0.5 cm surrounding the tumor. Two senior pathologists and two senior ultrasound physicians independently assessed lymphocytic infiltration, eosinophilic changes of follicular epithelium, and the proportion of hypoechoic areas in pathology and ultrasound images, respectively. A machine learning model, CCH-NET, was developed using linear regression and t-distributed stochastic neighbor embedding (t-SNE) techniques. The dataset was divided into a training set (80%) and a validation set (20%) to compare the diagnostic accuracy of CCH-NET with that of senior ultrasound physicians. Results:In internal validation, CCH-NET achieved a diagnostic accuracy of 88.89% for both antibody-positive and antibody-negative groups, significantly higher than the 66.67% accuracy of senior ultrasound physicians ( P<0.01). In external validation, CCH-NET achieved 75.00% and 66.67% accuracy for the two groups, compared to 50.00% by senior ultrasound physicians. For the control group, both methods achieved 93.33% accuracy. The AUC of CCH-NET was 0.848, outperforming senior ultrasound physicians (0.681) ,demonstrating superior diagnostic performance. Conclusion:The radiomics-based CCH-NET model, using non-nodular hypoechoic areas as a specific indicator, can accurately identify early SN-HT in euthyroid patients. It significantly outperforms senior ultrasound physicians, improving diagnostic accuracy and reducing missed diagnoses.
