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.

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.

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.

Objectives:To investigate the epidemiological characteristics and ethnic differences of cardiovascular-kidney-metabolic syndrome(CKM)among the Hani,Dai,Bai,and Lisu populations in Yunnan Province,and to provide evidence for developing effective prevention and control strategies for CKM.Methods:A cross-sectional survey was conducted among four ethnic minority groups.A total of 3 906 permanent residents aged 18 years and older were enrolled using a multistage cluster random sampling method.CKM stages(0-4)were defined based on the 2023 American Heart Association criteria,stages 3-4 were classified as advanced CKM.Descriptive statistics and chi-square tests were used to compare the prevalence of CKM stages across ethnic groups.Modified Poisson regression was applied to estimate relative risk(RR)and 95%confidence intervals(CI)for factors associated with advanced CKM.Results:The prevalence rates of CKM stage 1 and above among the Hani,Dai,Bai and Lisu ethnic groups were 80.1%,87.3%,84.8%and 67.8%,respectively.The prevalence of CKM was generally higher in males than in females,and the prevalence of CKM increased significantly with age.The Dai ethnic group had the highest prevalence of advanced CKM(24.7%,95%CI:22.1%-27.4%),while the Lisu ethnic group had the lowest prevalence of advanced CKM(13.7%,95%CI:11.5%-15.9%).Modified Poisson regression analysis showed that older age and higher body mass index were common risk factors for advanced CKM across all four ethnic groups.Additionally,except for the Lisu ethnic group,the other three ethnic groups had specific individual risk factors:among the Hani ethnic group,low educational attainment(RR=2.18,95%CI:1.12-4.25)and low income(RR=1.47,95%CI:1.00-2.18)were the primary risk factors of CKM.Among the Dai ethnic group,smoking(RR=1.60,95%CI:1.07-2.37)and a family history of cardiovascular disease(RR=1.61,95%CI:1.14-2.27)are the primary risk factors of CKM.Among the Bai ethnic group,male gender(RR=0.48,95%CI:0.29-0.79)was the primary risk factor of CKM.Conclusions:The prevalence of CKM stage 1 or higher is relatively high among the four minority ethnic groups in Yunnan province.There are significant differences in staging characteristics and primary risk factors across ethnic groups,necessitating the development of stratified,differentiated intervention strategies to achieve precise prevention and control and ethnic health equity in terms of CKM.

Objective To explore the expression levels and clinical significance of serum angiopoietin-like protein 8(ANGPTL8),cardiotrophin like cytokine factor 1(CLCF-1)in patients with primary nephrotic syndrome(PNS).Methods 124 patients with PNS admitted to Yulin Hospital,the First Affiliated Hospital of Xi'an Jiaotong University from January 2020 to February 2023 were selected as the PNS group,and 60 healthy individuals who underwent physical examinations during the same period were selected as the control group.Enzyme linked immunosorbent assay(ELISA)was used to detect serum levels of ANGPTL8 and CLCF-1.The correlation between serum ANGPTL8,CLCF-1 and renal function indicators were analyzed by Pearson correlation analysis.Logistic regression analysis was used to analyze the influencing factors on the prognosis of PNS patients.The evaluation value of serum ANGPTL8 and CLCF-1 was analyzed by analyzing receiver operating characteristic curve.Results The serum ANGPTL8(22.16±3.27 μg/L),CLCF-1(89.71±11.04 ng/L),24-hour urine protein(5.79±1.45g/24h),blood urea nitrogen(10.20±1.41mmol/L)and blood creatinine(191.44±21.52μmol/L)in the PNS group were higher than those in the control group(3.08±0.46μg/L,14.20±3.78ng/L,0.09±0.03 g/24h,4.88±1.21mmol/L,70.34±11.26μmol/L),while blood albumin was lower than those in the control group(25.06±2.80g/L vs 42.11±3.37g/L),and the differences were statistically significant(t=25.088～51.109,all P＜0.001).Serum ANGPTL8 and CLCF-1 were positively correlated with 24-hour urine protein,blood urea nitrogen and blood creatinine(r=0.636～0.789,all P＜0.001),while negatively correlated with blood albumin(r=-0.712,-0.689,all P＜0.001).Compared with the good outcome group,the PNS patients in the poor outcome group had higher serum ANGPTL8,CLCF-1,while lower IgA,and the differences were statistically significant(t=24.403,12.455,5.974,all P＜0.001).Serum ANGPTL8,CLCF-1 were risk factors affecting the outcome of PNS patients,while IgA was a protective factor(Wald χ2=14.354,15.666,10.847,all P＜0.001).The AUC(95%CI)of the combined evaluation of serum ANGPTL8 and CLCF-1 for the outcome of PNS patients which was higher than that of serum ANGPTL8 and CLCF-1,and the differences were statistically significant(Z=4.265,4.810,all P＜0.001).Conclusion The expression of serum ANGPTL8 and CLCF-1 are elevated in PNS patients,which are related to renal function indicators.The combination of the two has high evaluation value for evaluating the prognosis of PNS patients.

Objective To analyze the medication rules and clinical experience of Qin Zujie in treating virtual labor based on data mining.Methods Outpatient medical records of Qin Zujie,diagnosed with deficiency syndrome at Ethnic Medicine Characteristic Diagnosis and Treatment Center,Guangxi International Zhuang Medical Hospital from January to December 2024 were selected.A standardized database was established and processed,yielding 148 clinical prescriptions containing 171 herbal ingredients.Frequency analysis,association rule analysis,and cluster analysis were employed to examine medication rules and clinical experience.Results The 20 Chinese herbal ingredients used more than 30 times each,with the first three being Zhigancao,Baizhu,Danggui.These herbs are primarily warm in nature,neutral in temperature,and slightly cold in effect,characterized by sweet,pungent,and bitter flavors.They mainly affect the spleen meridian and function to tonify deficiency,with Qi-tonifying herbs being the most common.Through association rule analysis,the most frequently combined pairs were Baizhu-Dangshen.Cluster analysis identified three core prescription clusters.Conclusion Qin Zujie's academic thought of treating virtual labor is to supplement deficiency as the main,detoxification as the auxiliary,and treat both the symptoms and the causes.

Objective To investigate the effect of clozapine on neuronal differentiation and proliferation of human glioma cells.Methods Hematoxylin-eosin(HE)staining was used to observe the effect of clozapine on the morphology of human glioma cell A172.Immunocytochemistry was used to detect the expression of neuronal markers neuronal nuclei antigen(NeuN)and microtubule-associated protein 2(MAP2),as well as the expression of astrocytic markers glial fibrillary acidic protein(GFAP)and S100 calcium binding protein B(S100B),and oligodendrocytic markers myelin basic protein(MBP)and Olig2.ki-67detection,CCK-8 assay and clone formation assay were used to assess the effects of clozapine on the cell proliferation of A172.SwissTargetPrediction,GeneCards,and STRING data-bases were utilized to predict the potential mechanism of clozapine.Western blot was used to detect the expression level of β-catenin.Results Clozapine(30μmol/L)changed the morphology of A172 cells,with elongated cell projection.Clozapine induced the expression of neuronal markers NeuN and MAP2 in A172 cells,without inducing the expression of astrocytic or oligodendrocytic markers.Clozapine significantly inhibited the proliferation of A172 cells.Database analysis suggested that the mechanism of clozapine might be related to the Wnt signaling pathway.Clozapine down-regulated the expression of β-catenin in A172 cells.Conclusion Clozapine induced neuronal differentiation of human glioma cells A172,and inhibited their proliferation.
