Schistosomiasis cirrhosis (SAC), as the core pathological outcome of late-stage schistosomiasis, is an important challenge to global public health. Notably, there is still a significant disease burden, especially in the traditional endemic areas, such as the Yangtze River Basin in China. SAC has unique pathogenic characteristics, including insect-derived molecular-driven disease, chronic inflammation dominated by Th2 immunity, delayed pathogenicity, noticeable symptoms of portal hypertension, and an absence of significant correlation with liver cancer. Therefore, future research should focus on the determinants of individual susceptibility to SAC onset, the core mechanism of liver lesion progression post-pathogen clearance, time nodes, and intervention methods. Additionally, finding the high-risk individuals, analyzing of pathological mechanisms, and optimizing intervention strategies will help in promoting the development of clinical prevention and control and translational research.

Osteoporotic distal radius fracture (ODRF), a common fragility fracture in elderly patients, poses a significant threat to patients′ life and health due to its high incidence and disability rate. Both traditional Chinese medicine and Western medicine have accumulated extensive clinical experience in the diagnosis, treatment and rehabilitation of ODRF. However, there is currently a lack of specific guideline on how to effectively integrate the strengths of the two medical systems. To standardize the collaborative diagnosis and treatment of ODRF using integrated traditional Chinese and Western medicine, the Clinical Practice Guideline Working Group for the clinical practice guideline for the diagnosis and treatment of osteoporotic distal radius fracture through integrated traditional Chinese medicine and Western medicine was established in September 2024, led by the Third Affiliated Hospital of Yunnan University of Chinese medicine (Kunming Hospital of Chinese Medicine) with the participation of many medical institutions across China. Protocol for the guideline was then formulated to detail each key aspect in the development of the guideline and explain the related procedures, aiming to ensure a standardized, orderly and transparent development.

The patient, an 11-year-old girl, was admitted with recurrent fever for 20 days, worsening with abdominal distension for 7 days. Upon admission, she presented with recurrent fever, lymphadenopathy, hepatosplenomegaly, polyserositis, and multiple organ dysfunction. Lymph node pathology and clinical manifestations confirmed the diagnosis of idiopathic multicentric Castleman disease-TAFRO syndrome. Treatment with siltuximab combined with glucocorticoids was initiated, followed by maintenance therapy with tocilizumab. The patient is currently in complete clinical remission. Therefore, once a child is diagnosed with idiopathic multicentric Castleman disease -TAFRO syndrome, early use of siltuximab should be considered for rapid disease control, followed by tocilizumab for maintenance therapy.

OBJECTIVES:
To investigate the molecular epidemiology of children with phenylketonuria (PKU) in Gansu, China, providing foundational data for intervention strategies.
METHODS:
A retrospective analysis was conducted on 1 159 PKU families who attended Gansu Provincial Maternity and Child Care Hospital from January 2012 to December 2024. Sanger sequencing, multiplex ligation-dependent probe amplification, whole exome sequencing, and deep intronic variant analysis were used to analyze the PAH gene.
RESULTS:
For the 1 159 children with PKU, 2 295 variants were identified in 2 318 alleles, resulting in a detection rate of 99.01%. The detection rates were 100% (914/914) in 457 classic PKU families, 99.45% (907/912) in 456 mild PKU families, and 96.34% (474/492) in 246 mild hyperphenylalaninemia families. The 2 295 variants detected comprised 208 distinct mutation types, among which c.728G>A (14.95%, 343/2 295) had the highest frequency, followed by c.611A>G (4.88%, 112/2 295) and c.721C>T (4.79%, 110/2 295). The cumulative frequency of the top 23 hotspot variants reached 70.28% (1 613/2 295), and most variant alleles were detected in exon 7 (29.19%, 670/2 295).
CONCLUSIONS
Deep intronic variant analysis of the PAH gene can improve the genetic diagnostic rate of PKU. The development of targeted detection kits for PAH hotspot variants may enable precision screening programs and enhance preventive strategies for PKU.

OBJECTIVE:
To investigate the effect and mechanism of Shuangshi Tonglin Capsules (SSTL) in the treatment of prostate fibrosis (PF).
METHODS:
Human prostate stromal cells (WPMY-1) were used for in vitro experiments to establish PF cell models induced with estradiol (E2). The cell proliferation, migration and clonogenic capacity were determined by cell counting kit-8, scratch assay, and crystal violet staining, respectively. Sprague-Dawley rats were used for in vivo experiments. The changes in histomorphology and organ index of rat prostate by SSTL were determined. Pathologic changes and collagen deposition changes in rat prostate were observed by haematoxylin and eosin (HE) and Masson staining. Enzyme-linked immunosorbent assay kits were used to determine changes in rat PF markers fibroblast growth factor-23 (FGF-23), E2 and prostate specific antigen (PSA). Mechanistically, changes in oxidative stress indicators by SSTL were determined in WPMY-1 cells and PF rats. Then the expressions of nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) and transforming growth factor-β1 (TGF-β1)/Smad pathway-related proteins as well as Nrf2 and TGF-β1 mRNA were further detected by Western blot or quantitative real-time polymerase chain reaction both in vivo and in vitro.
RESULTS:
In the efficacy study, SSTL significantly reduced the proliferation, migration, and clonogenic ability of cells, improved the morphology of the glandular tissue, significantly reduced the prostate index, reduced glandular fibrous tissue and collagen deposition, and resulted in a significant decrease in the levels of FGF-23, E2 and PSA (P<0.01 or P<0.05). In the mechanistic study, SSTL ameliorated oxidative stress by significantly increasing superoxide dismutase and glutathione peroxidase levels and decreasing malondialdehyde level in WPMY-1 cells and rats (P<0.01 or P<0.05). SSTL significantly elevated the expressions of Nrf2, HO-1, NAD(P)H quinone oxidoreductase 1 (NQO-1), and Smad7 proteins in both cells and rats, and significantly decreased the expressions of TGF-β1, collagen I, α-smooth muscle actin and Smad4 proteins (P<0.01 or P<0.05). SSTL also elevated the content of Nrf2 mRNA and decreased the content of TGF-β1 mRNA in cells and rats (P<0.01 or P<0.05). The Nrf2 inhibitor ML385 was added in in vitro experiments to further validate the pathway relevance.
CONCLUSION
SSTL was effective in improving PF in vivo and in vitro, and its mechanism of action may function through the Nrf2/TGF-β1 signaling pathway.

Objective To evaluate the surgical technique and clinical value of laparoscopic bladder diverticulectomy guided by inserting ureteral catheters into the diverticulum under plasmakinetic resectoscope.Methods From December 2018 to May 2024,9 patients underwent laparoscopic bladder diverticulectomy in combination with resectoscope.Each patient had a solitary bladder diverticulum with a median maximum diameter of 6.40(5.70,7.40)cm(range:5.0~8.5 cm).Among the 9 patients,3 patients had concurrent benign prostatic hyperplasia(BPH)and simultaneously underwent transurethral plasmakinetic resection of the prostate;1 patient had concurrent both BPH and bladder calculi,requiring simultaneously underwent plasmakinetic resection of the prostate and bladder calculi removal;2 patients required ureteral reimplantation as the diverticulum was directly involving the ureteral orifice;1 case underwent ureteroscopic double-J stent implantation because the opening of the ipsilateral ureter was adjacent to the entrance of the diverticulum.Results Bladder diverticulectomy was successfully performed in the all patients.Median operative time was 160.00(120.00,317.50)min(range:85~345 min).Median estimated blood loss was 20.00(10.00,150.00)mL(range:10~300 mL).No iatrogenic injuries to adjacent organs were observed.Pelvic drains were removed 1~3 d postoperatively,with no urine leakage.Urinary catheters were maintained for 7~10 d after operation.Follow-up at 3~12 months showed no recurrence or hydronephrosis in any of the patients.Conclusion Laparoscopic resection of bladder diverticula guided by ureteral catheter placed into bladder diverticula by means of resectoscope has the advantages of less trauma,less bleeding and faster recovery,and is an effective measure for the treatment of bladder diverticula.
7.The Technological Frontiers,Computational Paradigms and Emerging Challenges of Single-cell and Spatial Omics
Chinese Journal of Biochemistry and Molecular Biology 2025;41(11):1559-1565
Single-cell and spatial omics technologies are spearheading a profound paradigm shift in the life sciences,moving beyond'population averages'to'single-cell resolution'and reintegrating'cellu-lar constitution'with'tissue spatial architecture',thereby dramatically advancing our understanding of biological complexity.This review provides a brief comprehensive overview of recent advancements in the field.Technologically,the evolution has progressed from single-cell transcriptomics to integrated approa-ches capturing multiple molecular layers simultaneously,while the emergence of transcriptome-badsed spatial omics has successfully preserved the spatial positioning of cells or microscosystem within native tis-sues,and further enabling spatial epigenomics and spatial-multiomics.Computationally,artificial intelli-gence and machine learning have become central engines,powering tools for data integration,spatial de-convolution,cellular communication and other novel foundation models,which not only tackle the chal-lenges of massive datasets but also serve as instruments for novel biological discovery.These technological leaps have fostered significant theoretical innovations.In clinical translation,these technologies,particu-larly in precision oncology,demonstrate transformative potential by dissecting tumor heterogeneity,map-ping the spatial architecture of the tumor immune microenvironment,and enabling disease modeling through single-cell-guided deconvolution of bulk data,offering new avenues for diagnosis,prognosis,and personalized therapy.Despite ongoing challenges in technological throughput,computational scalability,and clinical integration,the continued convergence of single-cell and spatial omics with AI promises to propel basic research towards a more mechanistic and predictive era,ultimately reshaping the future of precision medicine.

Albendazole-glucan particles(ABZ-GPS)and abendazole(ABZ)were used to treat secondary alveolar echinococ-cosis in mice.The therapeutic effects of ABZ-GPS on alveolar echinococcosis in vivo were evaluated,and the feasibility of using glucan particles as anti-hydatid drug carriers was further verified.Mice with echinococcosis were randomly divided into an ABZ group,glucan nanoparticle(GP)group,ABZ-GPS group,and control group.After four courses of administration with a final concentration of 50 mg/mL,the therapeutic effects of ABZ-GPS were evaluated on the basis of imaging,histopathological changes,ultrastructure,and immunology.After ABZ-GPS and ABZ administration,clear liver lesion tissue necrosis and large numbers of infiltrating lymphocytes were observed.Significant differences in the average cyst wet weight(t=7.83,P<0.05),were observed between the ABZ-GPS group and ABZ group.Imaging revealed that ABZ-GPs were targeted to liver tissue.Pa-thology and ultrastructure analyses demonstrated that the alveolar hydatid cells in the liver in the control group and GP group grew well,and the vesicles were large,filled with cystic fluid,and translucent or transparent;the cyst wall tension was high;no calcification was observed;the stratum corneum and germinal layer were clear;and more fertile capsules and different num-bers of protocephalospora were present in the liver.In the ABZ group,the capsular cavity collapsed,and showed partial necro-sis and lymphocyte infiltration.In the ABZ-GP group,the corneum and germinal layer of echinococcus vesicles were difficult to identify,and we observed bulbous necrosis,central calcification,fibrous tissue hyperplasia,inflammatory cell infiltration,coarser,shorter or absent microvilli of the germinal layer,nuclear shrinkage,dissolution or disappearance,clear expansion of cytoplasmic microtubules,and myelin-like or vacuole-like changes.Therefore,ABZ-GPs showed good targeting and killing ac-tivity in vivo in mice with secondary alveolar coccosis.
