Objective To investigate the effect of tritiated water on the immune system of zebrafish and its potential molecular mechanism. Methods Zebrafish embryos (2.5 to 3 hours post-fertilization [hpf]) were exposed to 3.7 × 10⁴ Bq/mL tritiated water (tritiated water group), and those exposed to E3 culture medium were used as the control group. The mortality rate, hatching rate, deformity rate, heart rate, body length, yolk sac area, neutrophil count in the tail, immune-related gene expression, and immune-related protein expression of zebrafish in the two groups were determined. Then transcriptome technology was used to further analyze the possible mechanism of tritiated water affecting the immune system of zebrafish. Results Compared with the control group, zebrafish at 72 hpf in the tritiated water group had no significant changes in the mortality rate, hatching rate, deformity rate, body length, and yolk sac area((t = 0.9045, 0.5000, 1.0000, 0.7238, 0.0337, P = 0.4169, 0.6433, 0.3739, 0.4785, 0.9735), but had significantly increased heart rate(t = 4.575，P = 0.002). At 4 days post-fertilization (dpf), the neutrophil count in the tail of zebrafish in the tritiated water group was significantly increased(t = 2.563，P = 0.0196), the mRNA expression of TNF-α was significantly decreased(t = 2.891, P = 0.045), the protein expression of nuclear factor-kappa B (NF-κB) was significantly increased(t = 3.848, P = 0.018), and the protein expression of NLRP3 was significantly decreased(t = 14.98, P = 0.001). At 7 dpf, the neutrophil count in the tail and the protein expression levels of NF-κB, NLRP3, and interleukin-1β were significantly decreased(t = 3.772, 7.048, 15.620, 4.423, P = 0.014, 0.002, 0.0001, 0.012). Transcriptome sequencing revealed that differentially expressed genes were mainly enriched in the “neutrophil activation” and “platelet activation pathways” at 4 dpf and in the “neutrophil apoptosis”, “ferroptosis”, and “necroptosis” pathways at 7 dpf. Conclusion Tritiated water exposure induces a temporally dynamic immune response in zebrafish, potentially affecting immune homeostasis by regulating neutrophil activation and apoptosis, as well as the expression of NF-κB and NLRP3.

OBJECTIVE: To observe the effects of antagonistic needling therapy on lower limb spasticity and the muscle morphology of the tibialis anterior and gastrocnemius in patients with stroke. METHODS: A total of 100 patients with post-stroke lower limb spasticity were randomly divided into an antagonistic needling group (50 cases, 1 case dropped out) and a routine acupuncture group (50 cases, 1 case dropped out). Both groups received basic treatment and rehabilitation training. The routine acupuncture group was treated with scalp acupuncture at anterior oblique line of vertex-temporal and vertex lateral line 1, combined with body acupuncture at Jianyu (LI15), Hegu (LI4), Zusanli (ST36), Taichong (LR3), etc. on the affected side, with Quchi (LI11) and Hegu (LI4), Zusanli (ST36) and Fenglong (ST40), Yanglingquan (GB34) and Taichong (LR3) connected to an electroacupuncture device, using disperse wave at 2 Hz of frequency. The antagonistic needling group used the same scalp and upper limb acupoints as the routine acupuncture group, with additional antagonistic needling on the lower limb at Yanglingquan (GB34), Qiuxu (GB40), Jiexi (ST41), and Xuanzhong (GB39) on the affected side, with Quchi (LI11) and Hegu (LI4), Yanglingquan (GB34) and Qiuxu (GB40), Jiexi (ST41), and Xuanzhong (GB39) connected to an electroacupuncture device, using disperse wave at 2 Hz of frequency. Both groups received treatment once daily for 6 consecutive days per course, with a total of 4 courses. The modified Ashworth scale (MAS), Holden functional ambulation classification (FAC), lower limb Fugl-Meyer assessment (FMA), composite spasticity scale (CSS), and musculoskeletal ultrasound parameters (thickness and fiber length of the tibialis anterior and gastrocnemius, and pennation angle of the gastrocnemius on both sides) were evaluated before and after treatment. Clinical efficacy was compared between the two groups. RESULTS: Compared before treatment, the MAS grades and CSS scores were decreased in both groups after treatment (P<0.01), with greater reductions in the antagonistic needling group (P<0.05, P<0.01). FAC grades and FMA scores were increased in both groups after treatment (P<0.01, P<0.05), with greater improvements in the antagonistic needling group (P<0.05). The muscle thickness, fiber length of the tibialis anterior, the muscle thickness, fiber length and pennation angle of the gastrocnemius on the affected side were improved in both groups after treatment (P<0.01), with greater improvements in the antagonistic needling group (P<0.01, P<0.05). On the unaffected side, these parameters were also increased after treatment in both groups (P<0.01, P<0.05), but the antagonistic needling group showed smaller increases than the routine acupuncture group (P<0.01, P<0.05). The total effective rate in the antagonistic needling group was 91.8% (45/49), higher than 81.6% (40/49) in the routine acupuncture group (P<0.05). CONCLUSION Antagonistic needling could effectively reduce spasticity, improve motor function, and enhance muscle structure in patients with post-stroke lower limb spasticity.

OBJECTIVES: To evaluate the osteogenic efficacy of three-dimensional printing individualized titanium mesh (3D-PITM) as a scaffold material in guided bone regeneration (GBR). METHODS: 1) Patients undergoing GBR for alveolar bone defects were enrolled as study subjects, and postoperative healing complications were recorded. 2) Postoperative cone beam computed tomography (CBCT) scans acquired at least 6 months post-surgery were used to calculate the percentage of actual bone formation volume. 3) Alveolar bone specimens were collected during the first-stage implant surgery for histomorphometric analysis. This analysis quantitatively measured the proportions of newly formed bone and newly formed unmineralized bone within the specimens. Specimens were categorized into three groups based on healing complications (good healing group, wound dehiscence group, 3D-PITM exposure group) to compare differences in the proportions of newly formed bone and newly formed unmineralized bone. RESULTS: 1) Twelve patients were included. Guided bone regeneration failed in one patient, and 3D-PITM exposure occurred in three patients (exposure rate: 25%). 2) The mean percentage of actual bone formation volume in the 11 successful guided bone regeneration cases was 95.23%±28.85%. 3) Histomorphometric analysis revealed that newly formed bone constituted 40.35% of the alveolar bone specimens, with newly formed unmineralized bone accounting for 13.84% of the newly formed bone. Intergroup comparisons showed no statistically significant differences (P>0.05) in the proportions of newly formed bone or newly formed unmineralized bone between the good healing group and the wound dehiscence group or the 3D-PITM exposure group. CONCLUSIONS 3D-PITM enables effective bone augmentation. Radiographic assessment demonstrated favorable bone formation volume, while histological analysis confirmed substantial formation of newly formed mineralized bone within the surgical site.

Objective:To investigate the efficacy and safety of venetoclax and azacitidine combined with GHA (human granulocyte colony stimulating factor, homoharringtonine and low-dose cytarabine) priming regimen in treatment of patients with relapsed/refractory acute myeloid leukemia.Methods:A retrospective case series study was conducted. Twenty-three patients with relapsed/refractory acute myeloid leukemia (non-acute promyelocytic leukemia) who received treatment with the combination of venetoclax and azacitidine with GHA priming regimen at the Second Affiliated Hospital of Xi'an Jiaotong University from October 2020 to July 2024 were selected, and the treatment efficacy, minimal residual disease (MRD)-negative rate in patients with comprehensive complete remission (cCR) (including complete remission, complete remission with partial hematologic recovery and complete remission with incomplete hematologic recovery) and the adverse reactions were analyzed; patients were followed-up, and their overall survival (OS) was analyzed by using Kaplan-Meier method.Results:The median age of the 23 patients was 60 years (range: 21-79 years), including 10 males and 13 females. The cCR rate for 1 course of treatment was 52.2% (12/23), with 4 cases of MRD negative among cCR patients; 5 cases received 2 courses of treatment, with 3 cases achieving cCR, of which 2 cases were MRD negative; 2 cases received 3 courses of treatment, with 1 case achieving complete remission with incomplete hematologic recovery. Six patients underwent allogeneic hematopoietic stem cell transplantation. The patients were followed up until July 31, 2024, and the median follow-up period was 5.3 months (range: 1.1-41.7 months). Ten cases survived, 12 cases died, 1 case was lost to follow-up, and the median OS time of 23 patients was 7.9 months. The 6-month OS rate was 60.2% (95% CI: 42.7%-84.8%), and the 12-month OS rate was 44.6% (95% CI: 26.8%-74.3%). Common adverse reactions during treatment included infection [69.6% (16/23)], nausea [56.5% (13/23)], febrile neutropenia [52.2% (12/23)], bleeding [52.2% (12/23)], vomiting [34.8% (8/23)], and pneumonia [34.8% (8/23)]. Conclusions:The combination of vinaclotide and azacitidine with GHA priming regimen has certain efficacy and good safety in the treatment of relapsed/refractory acute myeloid leukemia.

Objective To investigate the correlation between serum adipokine levels and insulin resist-ance in preterm infants with early extrauterine growth retardation(EUGR).Methods A total of 130 preterm infants admitted to the neonatal intensive care unit of the hospital from March 2023 to March 2024 were se-lected as the research subjects.They were divided into the EUGR group(n=63)and the non-EUGR group(n=67)based on whether their weight Z-score at 2 weeks of age was ≥-1.28.Clinical data of the preterm infants and their mothers were collected.Blood samples were collected at 14 days after birth to measure serum insulin,adiponectin,resistin,leptin,blood glucose,total cholesterol,high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),and triglyceride levels.The homeostasis model assessment of insulin resistance(HOMA-IR)was calculated,and the correlation between HOMA-IR and adipokine levels as well as lipid levels was analyzed.Results Compared with the non-EUGR group,the EUGR group had a high-er proportion of mothers with pregnancy-induced hypertension.The preterm infants in the EUGR group had higher levels of insulin,resistin,leptin,triglycerides,and HOMA-IR,and lower levels of HDL-C,with statisti-cally significant differences(P＜0.05).In the EUGR group,HOMA-IR was positively correlated with adi-ponectin,resistin,and leptin levels,while in the non-EUGR group,HOMA-IR was positively correlated with adiponectin levels(P＜0.05).Conclusion Insulin resistance in preterm infants with early EUGR may be re-lated to changes in adipokine levels.

Objective:To screen differentially expressed genes (DEGs) associated with liver cancer by bioinformatics analysis method, and to investigate the mechanism of the minichromosome maintenance protein 2 ( MCM2) and replication factor C subunit 4 ( RFC4) genes in liver cancer in vitro. Methods:Gene expression profiling data of 80 and 36 hepatocellular carcinoma tissues and 307 and 13 cirrhotic tissues were obtained from the GSE25097 and GSE98620 datasets of the gene expression analysis (GEO) database, respectively. Gene expression profiling data of 374 liver cancer tissues and 50 normal liver tissues were downloaded from the cancer genome atlas (TCGA) database. Limma and DESeqs R software were used to process the gene expression profiling data, construct protein-protein interaction networks, and analysis the relevance of these genes to survival. Weighted gene co-expression network analysis was performed to screen out the core genes. Liver cancer SMMC7721 cells were transfected with MCM2 blank plasmid (MCM2 control group), MCM2 overexpression plasmid [MCM2 WT1 group, MCM2 WT2 (2-fold WT1) group], RFC4 blank plasmid (RFC4 control group), and RFC4 overexpression plasmid [RFC4 WT1 group, RFC4 WT2 (2-fold WT1) group], respectively. The expression of MCM2 and RFC4 in liver cancer cell lines and their transfection levels were detected by real-time fluorescence quantitative reverse transcription PCR and Western blotting. The effects of MCM2 and RFC4 on the proliferation of hepatocellular carcinoma cells were detected by MTT assay and cell cloning assay, respectively. The effects of MCM2 and RFC4 on the migration of liver cancer cells were determined by the scratch assay. The effects of MCM2 and RFC4 on liver cancer cell invasion were detected by Transwell assay.Results:By bioinformatic analysis, 9 HCC DEGs were selected, including ubiquitin conjugating enzyme E2 T ( UBE2T), aurora kinase A ( AURKA), targeting protein for Xklp2 ( TPX2), MCM2, RFC4, ribonucleoside-diphosphate reductase subunit M2 ( RRM2), serine peptidase inhibitory factor Kazal type 1 ( SPINK1), collagen type XV alpha 1 chain ( COL15A1) and C-C motif chemokine 25 ( CCL25). Among the six genes associated with clinical stages, the MCM2 and RFC4 genes were found to be strongly associated with prognosis in liver cancer. The relative protein expression of MCM2 and RFC4 in HepG2 cells (1.83±0.07, 1.44±0.09) and SMMC7721 cells (1.74±0.05, 1.43±0.08) was higher than that in MIHA cells (1.00±0.02, 1.00±0.03), and all the differences were statistically significant (all P<0.05). The relative gene expression of MCM2 and RFC4 in HepG2 cells (14.30±0.12, 5.10±0.18) and SMMC7721 cells (10.60±0.11, 7.60±0.07) was higher than that in MIHA cells (1.00±0.05, 1.00±0.03), and all the differences were statistically significant (all P<0.05). Compared with the MCM2 control group, the absorbance values [(0.28±0.01 and 0.21±0.01) vs 0.18±0.03], the number of clonal cells [(717±12 and 782±29) cells vs (389±17) cells], the percentage migration [(0.43±0.02 and 0.68±0.01) vs 0.15±0.06], and the number of cellular invasions [(933±21 and 821±11) cells vs (409±16) cells] were higher in the MCM2 WT1 and MCM2 WT2 groups, and the differences were all statistically significant (all P<0.05). Compared with the RFC4 control group, the absorbance values [(0.30±0.02 and 0.21±0.01) vs 0.17±0.02], the number of cloned cells [(571±11 and 728±9) cells vs (373±23) cells], the percentage migration [(0.75±0.11 and 0.67±0.04) vs 0.34±0.07], and the number of cell invasion [(835±26 and 818±18) cells vs (629±12) cells] were higher in the RFC4 WT1 and the RFC4 WT2 groups, and the differences were statistically significant (all P<0.05). Conclusions:MCM2 and R FC4 genes play a role in promoting tumorigenesis and growth in hepatocellular carcinoma.

Objective To develop an erythrocyte-based delivery system for butyrylcholinesterase(BChE)that is capable of prophylaxis against organophosphorus nerve agents.Methods Recombinant BChE was produced and analyzed for oligomerization via polyacrylamide gel electrophoresis(PAGE)and Western blotting.A modified hypotonic preswelling method was employed to prepare BChE-loaded erythrocytes.The drug loading capacity and encapsulation efficiency were quantified using enzyme-linked immunosorbent assay(ELISA).Catalytic activity was assessed in vitro with an activity detection kit.The system was characterized via scanning electron microscopy(SEM),flow cytometry and a hematology analyzer.Results Recombinant BChE predominantly existed as dimers(85％dimer,15％monomer).The optimized volume ratio of erythrocytes to hypotonic solution was determined as 1:7.Compared with native and empty erythrocytes,BChE-loaded erythrocytes exhibited significantly higher catalytic activity(P＜0.001).The mean corpuscular volume of BChE-loaded erythrocytes increased(P＜0.001),while the mean content of corpuscular hemoglobin and hemoglobin in erythrocytes per 100 mL decreased(P＜0.001).SEM revealed no morphological differences(biconcave disc shape).Hypotonic preswelling moderately increased erythrocyte apoptosis(P＜0.001),but no statistical difference was observed between BChE-loaded and hypotonic-treated erythrocytes(P＞0.05).CD47 expression remained unchanged compared to native erythrocytes(P＞0.05).Conclusion The modified hypotonic preswelling method can generate BChE-loaded erythrocytes that retain the characteristics of native erythrocytes while conferring catalytic activity,offering a novel strategy for clinical intervention against organophosphorus poisoning.

ObjectiveTo explore the relationships between internet gaming disorder (IGD), interpersonal needs, loneliness, and depression in adolescents through the construction of a chain mediation model, to clarify the underlying mechanisms of these associations, and to provid a theoretical basis for depression prevention and intervention. MethodsBased on the data of the 7th Population Census, using convenient sampling method 1 106 adolescents aged between 10‒19 years in South China (176), North China (147), Central China (332), and East China (451) were selected to conduct a cross-sectional survey, with a ratio of 1∶1∶1.5∶2.5. The survey was conducted with a questionnaire consisting of general information (sex, age, grade, parents’ education level), the Chinese version of the IGDS9-SF, the INQ-15, the short-form of the ULS-8 and the PHQ-9 were used to evaluate the depression status of adolescents. Spearman correlation analysis was used to explore the correlation between the variables. A multiple-mediator model was constructed using IBM SPSS Statistics 22.0 PROCESS to examine the mediating effects of interpersonal needs and loneliness on the relationship between IGD and depression. The significance of the chain mediating effect was tested using the Bootstrap method. ResultsOverall, 39.06% (432/1 106) adolescents experienced depression. The incidence of depression among adolescents with smoking and without smoking was 62.50% and 38.36%, respectively. Similarly, the incidence of depression among adolescents with alcohol consuming and without alcohol consuming was 61.94% and 35.94%, respectively. There were statistically significant differences between IGD, interpersonal needs, loneliness, and depression (P<0.01). The chain mediation model demonstrated a good fit, and the bootstrap test showed that the 95%CI of each mediation path did not include 0, indicating significant mediation effects. The overall effect was 0.337. The direct effect of IGD on depression was significant (effect value=0.138, 95%CI:0.102-0.173, P<0.001). The mediation effects included three paths: ① IGD →interpersonal needs → depression (effect value=0.073, P<0.05), accounting for 21.47% of the total effect;② IGD→ loneliness → depression (effect value=0.093, P<0.05), accounting for 27.35%; and ③ IGD → interpersonal needs → loneliness → depression (effect value=0.036, P<0.05), accounting for 10.59%. ConclusionInterpersonal needs and loneliness independently and jointly mediate the relationship between IGD and depression among adolescents. To reduce depression and improve mental health in this population, measures should be taken to prevent and intervene in IGD, address adolescents’ social and emotional needs, enhance satisfaction of interpersonal needs, and reduce loneliness.

Objective:To summarize the clinical characteristics and factors that may affect the flare of patients with systemic lupus erythematosus (SLE).Methods:A total of 300 patients with SLE who were treated with standard treatment in the outpatient clinic of the department of rheumatology and immunology of the Second Affiliated Hospital of Air Force Military Medical University of PLA, were enrolled, and the patients were divided into 24 patients in the complete response group, 40 cases in the no response group, 192 cases in the treatment response group, and 44 cases in the low disease activity group according to the response to treatment. The differences in clinical characteristics and survival rates between the groups were compared and analyzed. Comparisons of count data were made using analysis of variance (ANOVA), comparisons of measurement data were made using the chi-square test or the Fisher′s ecact test, and survival rates were expressed as Kaplan-Meier curves. Cox regression analysis was adapted to explore risk factors for flare in these patients.Results:A total of 300 patients were followed. With a median follow-up time of 18 (1, 36) months, a total of 42 patients experienced flare. The clinical characteristics of the four groups were compared, and there were significant differences in age ( F=4.39, P=0.005), the presence of lupus nephritis ( χ2=12.66, P=0.005), hemoglobin level ( F=2.73, P=0.044), NLR level( F=3.88, P=0.010), cystatin C level( F=3.11, P=0.027), anti-RNP antibody ( χ2=12.04, P=0.007), anti-Sm antibody ( χ2=8.33, P=0.040), anti-SSB antibody ( P=0.014), anti-nucleosome antibody ( P=0.014), and anti-ribosomal P protein antibody ( χ2=11.83, P=0.008). There was no significant difference in survival between the four groups. Cox analysis showed that the combination of other autoimmune diseases [ HR(95%CI)=3.23(1.58, 6.57), P=0.001], anti-Sm antibody [ HR(95%CI)=2.15(1.04, 4.43), P=0.038], and anti-RNP antibody [ HR(95%CI)=2.54(1.13, 5.68), P=0.023] were risk factors for flare in patients with SLE who could reach the treatment target. Conclusion:Patients with SLE with different treatment responses have different clinical features, and all treatment can significantly improve the recurrence rate no matter what level of response to treatment. Patients concurrent with other autoimmune diseases, positive anti-Sm antibodies, and positive anti-RNP antibodies are at highrisk of flare.
