OBJECTIVE:
To analyze the clinical characteristics, treatment, and prognosis of seven pediatric patients with Acute myeloid leukemia (AML) positive for the t(16;21)(p11;q22) FUS::ERG fusion gene.
METHODS:
A retrospective analysis was carried out on the clinical data, treatment, and prognosis of seven AML patients with t(16;21)(p11;q22) FUS::ERG fusion gene admitted to Henan Children's Hospital between June 2015 and November 2024. Relevant literature was also reviewed. This study was approved by the Medical Ethics Committee of the Hospital (Ethics No.: 2024-102-001).
RESULTS:
Among 297 pediatric patients with AML, 7 cases (2.36%) were positive for the t(16;21)(p11;q22) FUS::ERG fusion gene, including 3 males and 4 females, with a median age of 11 years (range: 3 ~ 12 years). According to the FAB classification, these included 1 case of M2, 3 cases of M5, and 3 cases of AML-not otherwise specified (non-M3). All 7 patients were found to harbor the t(16;21)(p11;q22) translocation, with 3 cases showing additional chromosomal abnormalities. Immunophenotyping revealed universal expression of CD13, CD33, CD34, and CD117, with partial expression of CD56, CD4, CD64, CD123, CD15, CD38, CD11b, HLA-DR, cMPO, and CD16. One patient achieved complete remission (CR) after the first course of DAE (cytarabine + daunorubicin + etoposide) induction chemotherapy but relapsed and discontinued the treatment. Six patients received DAH (cytarabine + daunorubicin + homoharringtonine) induction therapy, of whom 2 achieved CR after two courses and underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT), resulting in an overall CR rate of 42.86%. Five children did not receive allo-HSCT and had a median overall survival of 9 months (range: 6 ~ 18 months). Two children who underwent transplantation achieved bone marrow morphological and molecular biological relapse at 6 and 9 months post-transplantation, respectively. After receiving combined chemotherapy and donor lymphocyte infusion, one child failed to achieve remission and died at 22 months post-transplantation, while the other has been followed up to date with positive fusion gene status. Their overall survival was 25 months and 30 months, respectively.
CONCLUSION
The t(16;21)(p11;q22) FUS::ERG fusion gene is rare in pediatric AML and associated with poor prognosis. Allo-HSCT may mitigate the adverse prognostic impact of the FUS::ERG fusion gene and contribute to prolonged survival.

Objective To investigate the prevalence of Clonorchis sinensis human infections in Congjiang County, Guizhou Province in 2023, so as to provide insights into formulation of the clonorchiasis control strategy. Methods Congjiang County was divided into eastern, western, southern, northern and central areas according to the geographical locations, and one township was randomly sampled from each area. Then, each administrative village was randomly sampled from each township, and 200 permanent residents over 3 years of age were randomly sampled from each village. Participants’ stool samples were collected for detection of C. sinensis eggs with the Kato-Katz technique (two slides for each stool sample), and the prevalence and intensity of C. sinensis infections were calculated. In addition, the risk factors of clonorchiasis were identified among participants using a questionnaire survey. Results A total of 1 001 residents were included, and the prevalence of C. sinensis infections was 16.28% (163/1 001), with mild infections as the predominant category of infection intensity [73.01% (119/163)]. The prevalence rates of C. sinensis human infections were 30.50% (61/200), 1.50% (3/200), 30.35% (61/201), 12.50% (25/200), and 6.50% (13/200) at five survey sites, respectively (χ2 = 107.03, P < 0.05), and there was a significant difference in the prevalence of C. sinensis infections between men [22.44% (112/499)] and women [10.16% (51/502)] (χ2 = 27.71, P < 0.05). The prevalence of C. sinensis infections was relatively high among participants at ages of 60 to 70 years [26.14% (23/88)], public servants [46.15% (6/13)], and Han ethnic participants [33.33% (5/15)]. The prevalence of C. sinensis infections was higher among participants with a habit of consuming raw or un-dercooked freshwater fish and shrimp [22.06% (90/408)] than among those without the habit [12.31% (73/593)] (χ2 = 16.85, P < 0.05), and there was no significant difference in the prevalence of C. sinensis infections between participants with [13.99% (41/293)] and without separation of raw and cooked chopping boards [17.23% (122/708)] (χ2 = 1.59, P > 0.05). In addition, the prevalence of C. sinensis infections was 8.70% (2/23) and 16.46% (161/978) among participants with and without fever complicated by discomfort in the right upper abdomen during the past half year (χ2 = 0.99, P > 0.05). Conclusions The prevalence of C. sinensis human infections was high in Congjiang County, Guizhou Province in 2023, and infections predominantly occurred among young and middle-aged men. Intensified health education among high-risk residents and alteration of dietary habits of consuming raw or undercooked freshwater fish or shrimp are recommended to reduce the prevalence of C. sinensis human infections.

ObjectiveTo evaluate the therapeutic effects of Huanglian Jiedutang on cerebral infarction injury in a mouse model of middle cerebral artery occlusion (MCAO) and to explore its mechanism of action on oligodendrocytes, particularly its potential in myelin repair. MethodsMultiple experimental approaches were used to evaluate cerebral ischemic injury and the effects of drug intervention. Laser speckle imaging was used to detect changes in cerebral blood flow, 2,3,5-Triphenyltetrazolium chloride (TTC) staining was used to measure infarct volume, and neurological function was scored according to the Zea-Longa criteria. Brain tissues were routinely embedded in paraffin and subjected to HE and Nissl staining to observe tissue structure and neuronal damage. Animals were divided into a sham group (n=24), model group (n=24), Huanglian Jiedutang group (n=24), and Ginkgo biloba extract (GBE) group (n=18). After 1 week of acclimatization, intragastric administration was initiated. The sham and model groups received normal saline, the Huanglian Jiedutang group was administered 1.82 g·kg-1, and the GBE group was administered 0.432 g·kg-1 after preparation as a 2.16 g·L-1 solution. All groups were treated for 5 consecutive days at a dose of 0.2 mL·(10 g)-¹·d-¹. The MCAO model was established after the final administration on day 6. Single-cell RNA sequencing was used to analyze brain tissue cellular composition and changes in oligodendrocyte subpopulations. Distinct subpopulations were identified by Uniform manifold approximation and projection (UMAP) dimensionality reduction and unsupervised clustering, and marker gene expression was analyzed. Pathway enrichment and causal inference were further performed using IPA. Finally, real-time quantitative PCR was used to verify mRNA expression changes of myelin-related genes. ResultsCompared with the sham group, the model group showed significantly increased neurological function scores (P<0.01), significantly impaired blood flow (P<0.01), significantly enlarged cerebral infarct area (P<0.01), and pathological changes including disordered cortical structural arrangement, aggravated cytoplasmic vacuolization, and increased Nissl bodies. Compared with the model group, the Huanglian Jiedutang and GBE groups showed significantly decreased neurological function scores (P<0.01), markedly restored blood flow levels (P<0.01), significantly reduced cerebral infarct area (P<0.01), and improvement in cortical structural disorder, alleviation of cytoplasmic vacuolization, and a reduction in Nissl bodies. Single-cell data showed that a myelin-associated oligodendrocyte (Mye-OL) subpopulation existed among oligodendrocytes, which was closely related to myelin generation. Compared with the sham group, the number of Mye-OL cells decreased in the model group. Compared with the model group, the number of Mye-OL cells increased in the Huanglian Jiedutang group. This subpopulation promoted the expression of myelin-related genes, including MOG, MBP, and MAG, via transcription factors such as OLIG1, OLIG2, NKX2-2, and SOX10, thereby regulating myelin generation, restoring cognition, and exerting therapeutic effects on acute cerebral infarction. Compared with the sham group, the mRNA expression levels of OLIG1, OLIG2, NKX2-2, and SOX10 were significantly downregulated in the model group (P<0.01), and the mRNA expression levels of myelin-related genes, including MOG, MBP, and MAG, were also significantly downregulated (P<0.01). In contrast, compared with the model group, the Huanglian Jiedutang and GBE groups showed significantly upregulated mRNA expression levels of OLIG1, OLIG2, NKX2-2, and SOX10 (P<0.01), and significantly upregulated mRNA expression levels of myelin-related genes, including MOG, MBP, and MAG (P<0.01). ConclusionHuanglian Jiedutang exerts therapeutic effects on acute cerebral infarction by regulating the OLIG1/2-NKX2-2-SOX10 signaling pathway to promote myelin generation by Mye-OL cells.

ObjectiveTo characterize the quality differences among different germplasm and introduced varieties of Bupleurum scorzonerifolium roots(BSR), and explore the underlying molecular mechanisms, providing a basis for high-quality production and quality control. MethodsWild BSR from Yulin(YLW) served as the quality reference, we conducted comparative analysis among YLW, locally domesticated wild germplasm in Yulin(YLC3), Daqing germplasm introduced and cultivated in Yulin(YLDQC3), and locally cultivated germplasm in Daqing(DQC3). A combination of traditional pharmacognostic methods and modern multi-omics analyses was employed, including macroscopic traits(appearance, odor), microscopic features(proportions of cork, phloem, xylem), cell wall component contents(hemicellulose, cellulose, lignin), carbohydrate contents(starch, water-soluble polysaccharides), marker compound contents(ethanol-soluble extracts, total saponins, liposoluble extracts, and saikosaponins A, B2, C, D), metabolomics, and transcriptomics, in order to systematically characterize quality differences and investigate molecular mechanisms among these samples. ResultsMacroscopically, Yulin-produced BSR(YLW, YLC3, YLDQC3) exhibited significantly greater weight, length, and upper and middle diameters than Daqing-produced BSR(DQC3). Odor-wise, YLW and YLC3 had a a fragrance taste, YLDQC3 had a rancid oil odor, and DQC3 had a sweet and fragrant taste. Microscopically, Yulin germplasm(YLW, YLC3) and Daqing germplasm(YLDQC3, DQC3) shared similar structural features, respectively. However, Yulin germplasm showed significantly higher proportions of cork and phloem, as well as stronger xylem vessel staining intensity compared to Daqing germplasm. Regarding various component contents, Yulin germplasm contained significantly higher levels of ethanol-soluble extracts, total saponins, and saikosaponins A, B2, C, D, while Daqing germplasm had significantly higher levels of hemicellulose, starch, and liposoluble extracts. After introduction to Yulin, the Daqing germplasm(YLDQC3) showed increased starch, water-soluble polysaccharides and liposoluble extracts contents, decreased cell wall component content, but no significant difference in other component contents. Metabolomics revealed that saponins and terpenes accumulated significantly in Yulin germplasm, while alcohols and aldehydes accumulated predominantly in Daqing germplasm. Transcriptomics indicated similar gene expression patterns within the same germplasm but specificity between different germplasms. Integrative metabolomic-transcriptomic analysis identified 145 potential key genes associated with the saikosaponin biosynthesis pathway, including one acetyl-coenzyme A(CoA) acetyltransferase gene(ACAT), one 3-hydroxy-3-methylglutaryl-coenzyme A synthase gene(HMGS), two hydroxymethylglutaryl-CoA(HMG-CoA) reductase genes(HMG), one phosphomevalonate kinase gene(PMK), one 1-deoxy-D-xylose-5-phosphate synthase gene(CLA), one hydroxymethylbuten-1-aldol synthase gene(HDR), two farnesyl pyrophosphate synthase genes(FPPS), one squalene synthase gene(SQS), one β-amyrin synthase gene(BAS), 102 cytochrome P450(CYP450) gene family members, and 32 uridine diphosphate-glucuronosyltransferase(UGT) gene family members. ConclusionAmong the three cultivated types, YLC3 most closely resembles YLW in appearance, microscopic features, contents of major bioactive constituents, metabolomic and transcriptomic profiles. Yulin germplasm exhibits superior saponin synthesis capability compared to Daqing germplasm, and Yulin region is more suitable for the growth of B. scorzonerifolium. Based on these findings, it is recommended that artificial cultivation in northern Shaanxi and similar regions utilize the local Yulin germplasm source cultivated for at least three years.

Abnormal synaptic plasticity is an early pathological feature of Alzheimer disease (AD). Synaptic damage and dysfunction initiate neuronal degeneration and death, ultimately leading to cognitive impairment. Traditional Chinese medicine (TCM) can effectively ameliorate cognitive dysfunction through multitarget regulation of synaptic plasticity. This review summarizes the mechanisms by which TCM, including active components, single herbs, and classical formulas, modulates synaptic plasticity, offering new insights for future research and clinical applications. Relevant experimental studies published between 2020 and 2024 were retrieved from major databases, including China National Knowledge Infrastructure, the National Science and Technology Library, Wanfang Data, Elsevier, ScienceDirect, PubMed, SpringerLink, and Web of Science. Network pharmacology and bioinformatics approaches were used to predict the therapeutic effects and mechanisms of TCM on AD-related synaptic plasticity. In total, 15 TCM single herbs and 11 TCM formulas were identified as enhancing AD-related synaptic plasticity. Additionally, 15 active ingredients targeting synaptic plasticity in AD were retrieved from TCM databases over the past decade. This review provides novel perspectives and strategic directions for future AD research and therapeutic development.

Animal model research on spleen and stomach diseases in traditional Chinese medicine (TCM) is of great significance for elucidating the nature of diseases and syndromes and for revealing the mechanisms of action of Chinese herbal medicinals. At present, studies on classical TCM syndrome models of spleen and stomach diseases mainly focus on spleen deficiency syndrome, liver constraint syndrome, and damp-heat syndrome. Model construction is mostly based on the etiological and pathophysiological characteristics of syndrome, and model evaluation primarily involves macroscopic manifestations and physicochemical indicators. This paper summarizes the current research status of animal models integrating disease and syndrome for seven common spleen and stomach diseases, including chronic gastritis and gastric precancerous lesions, gastroesophageal reflux disease, functional dyspepsia, inflammatory bowel disease, irritable bowel syndrome, functional constipation, and functional diarrhea. The modeling methods and characteristics of disease-syndrome combined animal models for each disease are analyzed. It is proposed that future research on disease-syndrome integration in spleen and stomach diseases should move toward syste-matic, precise, and integrative development, and that interdisciplinary and cross-disciplinary research approaches should be adopted to enhance the predictive value and application efficiency of disease-syndrome combined animal models.

ObjectiveTo observe the effect of modified Shibaotang on serum sex hormone levels in patients with male late-onset hypogonadism of kidney essence deficiency syndrome complicated with diabetes mellitus. MethodsA total of 60 patients with male late-onset hypogonadism of kidney essence deficiency syndrome complicated with diabetes mellitus,who met the inclusion criteria and were admitted to Yinchuan Hospital of Traditional Chinese Medicine from October 2022 to October 2023,were selected and randomly divided into an observation group and a control group,with 30 patients in each group. Both groups continued their original treatments,including blood glucose lowering and blood lipid regulation. The observation group was treated with modified Shibaotang,while the control group was treated with testosterone undecanoate capsules. The treatment lasted for 12 weeks. The changes in traditional Chinese medicine (TCM)syndrome scores,partial androgen deficiency in aging males (PADAM)symptom scores,glucose metabolism indexes [fasting plasma glucose (FPG),2-hour postprandial glucose (2 h PG),glycosylated hemoglobin (HbA1c)],and serum sex hormone indexes [sex hormone-binding globulin (SHBG),free testosterone (FT),total testosterone (TT),prolactin (PRL),luteinizing hormone (LH),follicle stimulating hormone (FSH),estrogen (E2)] were compared between the two groups before and after treatment. Safety was also evaluated. Results(1)Clinical efficacy comparison:After treatment,the clinical efficacy in both groups was similar,and there was no statistically significant difference between the two groups. (2)TCM syndrome score and PADAM symptom score comparison:After treatment,both groups showed a significant reduction in TCM syndrome scores and PADAM symptom scores (P<0.01),and the observation group showed a significantly greater reduction compared to the control group (P<0.05). (3)Glucose metabolism indexes comparison:After treatment,the levels of FPG,2 h PG,and HbA1c were significantly reduced in both groups (P<0.01),and there was no statistically significant difference between the two groups regarding FPG,2 h PG,and HbA1c levels after treatment. (4)Serum sex hormone indexes comparison:After treatment,the levels of FT,TT,PRL,LH,and FSH were significantly increased in both groups (P<0.01),while E2 levels were significantly decreased (P<0.01). There was no statistically significant difference between the two groups in the levels of FT,TT,PRL,LH,FSH,and E2 after treatment. There was also no significant difference in SHBG levels within or between the groups before and after treatment. During the clinical observation,neither group exhibited any obvious adverse reactions. ConclusionModified Shibaotang can significantly improve the clinical symptoms of male late-onset hypogonadism of kidney essence deficiency syndrome complicated with diabetes mellitus,reduce blood glucose,and increase sex hormone levels. The mechanism may involve the inhibition of aromatase transformation in adipocytes,promotion of GnRH production,and regulation of the hypothalamic-pituitary-gonadal axis function.

Objective:To analyze the clinical features and prognosis of patients with acute cerebral infarction with different variation coefficients of red blood cell distribution width.Methods:A total of 1 080 patients with acute cerebral infarction diagnosed and treated in the First Affiliated Hospital of Xinjiang Medical University from July 2021 to May 2023 were retrospectively selected as the study objects. The coefficient of variation of red blood cell distribution width was determined for all patients, among which 361 patients with the coefficient of variation of red blood cell distribution width was 11.91% to 14.89%(normal group), and 719 patients with the coefficient of variation of red blood cell distribution width was 14.90% to 23.76% (abnormal group). The clinical characteristics and prognosis of patients with acute cerebral infarction with different coefficient of variation of red blood cell distribution width were compared. Spearman test and Pearson test were used to analyze the correlation between the variation coefficient of red blood cell distribution width and clinical characteristics and prognosis of patients with acute cerebral infarction.Results:There were no significant differences in the proportion of cardiac embolism, arteriole occlusion, partial anterior circulation infarction, posterior circulation infarction and lacunar infarction between the two groups ( P>0.05). The proportion of large atherosclerosis, total anterior circulation infarction, recurrent infarction and prognosis grade 4, 5 and 6 in the normal group was lower than those in the abnormal group :48.48% (175/361) vs. 55.22% (397/719), 8.31% (30/361) vs. 96/719 (13.35%), 16.90% (61/361) vs. 25.03% (180/719), 11.91% (43/361) vs. 42.84% (308/719), 5.26% (19/361) vs. 11.68% (84/719), 0.83% (3/361) vs. 7.93% (57/719); the proportion of grade 0, 1 and 2 prognosis in the normal group were higher than that in the abnormal group: 13.85% (50/361) vs. 0.42% (3/719), 21.05% (76/361) vs. 4.17% (30/719), 21.88% (79/361) vs. 4.73% (34/719), there were statistical differences ( P<0.05). There were statistically significant differences in the variation coefficient of red cell distribution width in patients with acute cerebral infarction among different disease inducements, infarct parts, incidence times and prognosis grades ( P<0.05). Spearman test showed that the variation coefficient of red blood cell distribution width was positively correlated with the infarct volume in patients with acute cerebral infarction ( r = 0.591, P<0.05). The results of Pearson test showed that the variation coefficient of red blood cell distribution width was not correlated with the cause of disease and the location of infarction in patients with acute cerebral infarction ( P>0.05), but was positively correlated with the frequency of incidence and prognosis grade ( r = 0.079, 0.402, P<0.05). Conclusions:Higher coefficients of variation of erythrocyte distribution width are associated with larger infarct size, higher risk of recurrence, and worse prognosis in acute cerebral infarction.

Liposomes serve as critical carriers for drugs and vaccines,with their biological effects influenced by their size.The microfluidic method,renowned for its precise control,reproducibility,and scalability,has been widely employed for liposome preparation.Although some studies have explored factors affecting liposomal size in microfluidic processes,most focus on small-sized liposomes,predominantly through experimental data analysis.However,the production of larger liposomes,which are equally significant,remains underexplored.In this work,we thoroughly investigate multiple variables influencing liposome size during microfluidic preparation and develop a machine learning(ML)model capable of accurately predicting liposomal size.Experimental validation was conducted using a staggered herringbone micromixer(SHM)chip.Our findings reveal that most investigated variables significantly influence liposomal size,often interrelating in complex ways.We evaluated the predictive performance of several widely-used ML algorithms,including ensemble methods,through cross-validation(CV)for both lipo-some size and polydispersity index(PDI).A standalone dataset was experimentally validated to assess the accuracy of the ML predictions,with results indicating that ensemble algorithms provided the most reliable predictions.Specifically,gradient boosting was selected for size prediction,while random forest was employed for PDI prediction.We successfully produced uniform large(600 nm)and small(100 nm)liposomes using the optimised experimental conditions derived from the ML models.In conclusion,this study presents a robust methodology that enables precise control over liposome size distribution,of-fering valuable insights for medicinal research applications.
