ObjectiveTo investigate the effect of different exercise interventions on metabolism and liver parameters in patients with metabolic dysfunction-associated fatty liver disease （MAFLD）， and to provide evidence-based recommendations for clinical exercise rehabilitation. MethodsThis study was conducted according to the PRISMA guidelines， and the protocol was registered on the PROSPERO platform， with a registration number of CRD42025641717. PubMed， Web of Science， Scopus， Wiley Online Library， CNKI， Wanfang Data， and VIP were searched for related articles published up to September 2024. The Cochrane tool for assessing risk of bias was used to assess the quality of articles， and Stata MP 17.0 was used to perform the network meta-analysis. ResultsA total of 57 articles were included， involving 2 648 patients. The results showed that aerobic exercise combined with resistance exercise had the best effect in improving body mass index （mean difference ［WMD］=-0.97， 95% confidence interval ［CI］： -1.66 to -0.28］， P<0.05， surface under the cumulative ranking curve ［SUCRA］=85.4） and triglycerides （WMD=-29.6， 95%CI： -46.66 to 12.54， P<0.05， SUCRA=87.3）； resistance exercise was the optimal intervention method for improving total cholesterol （WMD=-15.99， 95%CI： -24.19 to -7.79， P<0.05， SUCRA=79.9） and glutamine transaminase （WMD=-8.08， 95%CI： -12.13 to -4.02， P<0.05， SUCRA=87.3）； low-intensity aerobic exercise had the best effect in improving aspartate aminotransferase （WMD=-4.3， 95%CI： -8.45 to -0.15， P<0.05， SUCRA=73.5）， gamma-glutamyl transpeptidase （GGT） （WMD=-3.26， 95%CI： -7.79 to 1.27， P>0.05， SUCRA=82.3）， and glycated hemoglobin （HbA1c） （WMD=-0.6， 95%CI： -2.02 to 0.82， P>0.05， SUCRA=78.8）； moderate-intensity aerobic exercise was the optimal intervention modality to improve Homeostasis Model Assessment of Insulin Resistance （WMD=-0.92， 95%CI： -1.51 to -0.33， P<0.05， SUCRA=69.4）. It should be noted that there were no significant differences in HbA1c and GGT across different exercise interventions （all P>0.05）， suggesting that there was currently no sufficient statistical evidence to support that exercise could improve these two indicators. ConclusionBased on the comprehensive league table and cumulative probability ranking， aerobic exercise combined with resistance exercise， resistance exercise， and low- and moderate-intensity aerobic exercise may be the best exercise modality for improving key indicators in MAFLD patients， and targeted exercise modalities should be selected for intervention against different indicators； however， due to limitations of the original studies， further studies are needed for validation and exploration.

Objective:To explore the survival and prognostic factors of a long-course venetoclax-based(VEN-based)regimen in patients with de novo acute myeloid leukemia(AML)and provide evidence for the maintenance treatment of AML.Methods:A retrospective study was conducted in patients who received a VEN-based regimen and completed at least four courses of efficacy evaluation at The First Affiliated Hospital of Nanchang University from May 2021 to January 2024.The composite complete response rate(cCR),minimal residual disease(MRD)-negative rate,overall survival(OS)time,relapse-free survival(RFS)time,and adverse events were analyzed.Results:Overall,30 newly diagnosed patients with AML were enrolled in this study.The median age was 65(range,53-78)years,and the median number of treat-ment cycles was 7(range,4-20)years.After one cycle,the CR-and MRD-negative rates were 80.0%and 63.3%,respectively.The cumulative cCR was 96.7%,and MRD negative rate was 80.0%,respectively.The median follow-up time was 21.3(95%confidence intervals 14.7-27.9)months.The median OS time was 32.3 months and RFS time was not reached.The 2-year OS and RFS rates were 70.6%and 54.8%,respect-ively.Univariate analysis suggested that ELN2017 risk stratification and relapse status affected RFS and OS(P<0.05).However,the multivari-ate analysis failed to reveal any relationship between these factors and survival(P>0.05).In terms of safety,hematological adverse events were the most common,followed by infections.Overall,the VEN-based regimen was tolerated for patients with AML.Conclusions:A long-course VEN-based regimen is effective and safe.More than half of patients survive for>2 years,and it can be used as an effective mainten-ance treatment option for patients with AML.

Bruton's tyrosine kinase inhibitors(BTKi)are a class of drugs approved for treating patients with B cell-related hematologic malig-nancies.They function by blocking B cell signaling,thereby affecting the development and proliferation of B cell-related tumors.Research has revealed that Bruton's tyrosine kinase(BTK)is also expressed in other cells,including mast cells,dendritic cells,granulocytes,platelets,and macrophages.Furthermore,BTK's downstream signaling pathways,such as the activation of phospholipase C gamma 2(PLCγ2),Fc re-ceptor signaling path ways,and Toll-like receptor signaling pathways,are associated with various diseases.These mechanisms provide a the-oretical foundation for using BTK in treating diseases other than B cell-related tumors.This article reviews the progress in the application of BTK for non-B-cell malignancies.

Objective To determine the content and distribution characteristics of the artificial radionuclide ¹³⁷Cs and the natural radionuclides ²¹⁰Pb, ²²⁶Ra, ²²⁸Ra, and ⁴⁰K in wild edible fungi, and calculate the committed effective dose due to ¹³⁷Cs and ²¹⁰Pb in wild edible fungi. Methods Thirty samples of wild edible fungi were collected and their caps and stems were separated. A total of 60 samples were measured for ¹³⁷Cs, ²¹⁰Pb, ²²⁶Ra, ²²⁸Ra, and ⁴⁰K using a BE5030 wide-energy, low-background, high-purity germanium γ spectrometer. The paired analysis of the four radionuclides ²²⁶Ra, ²¹⁰Pb, ¹³⁷Cs, and ⁴⁰K was performed using SPSS 11.5. Results Among the 60 samples, the detection rates and dry weight specific activity ranges of ¹³⁷Cs, ²¹⁰Pb, ²²⁶Ra, ²²⁸Ra, and ⁴⁰K were 97% and 0.62-384 Bq/kg, 73% and 6.4-159 Bq/kg, 52% and 0.7-28.8 Bq/kg, 5% and 0.43-2.18 Bq/kg and 100% and （77.4-264) × 10 Bq/kg, respectively. Conclusion Based on the analysis of the 60 samples, the detection rate of radionuclides is in the order of ⁴⁰K, ¹³⁷Cs, ²¹⁰Pb, ²²⁶Ra, and ²²⁸Ra. In terms of the specific activity, the distribution of ⁴⁰K and ²²⁶Ra in wild edible fungi in the same region is basically uniform, while the content of ²¹⁰Pb and ¹³⁷Cs fluctuates in different samples. Although ¹³⁷Cs and ²¹⁰Pb can be detected in most of the wild edible fungi, the annual committed effective dose due to ingestion of wild edible fungi is negligible.

Objective:To investigate the relationship between artificial radionuclide 137Cs and stable cesium (Cs) in wild edible fungi and seek potential correlations. Methods:A total of 30 samples, including the caps (with gills) and stipes of wild edible fungi, were collected from the northeastern region of China. The measurement and analysis of 137Cs were conducted following recommended procedures in GB/T 16145-2022, and stable Cs was determined using inductively coupled plasma mass spectrometry (ICP-MS). Then, the correlation analysis of data on 137Cs and stable Cs was performed using SPSS 11.5 software, and scatter plots were prepared using the Origin 21.0 software. Results:The fungi caps exhibited a specific activity of 137Cs ranging from 0.52 to 55.9 Bq/kg (dry weight) and a stable Cs content from 0.069 mg/kg to 16.2 mg/kg (dry weight). The stipes showed a specific activity of 137Cs ranging from 0.53 Bq/kg to 101 Bq/kg (dry weight) and a stable Cs content from 0.075 to 11.5 mg/kg (dry weight). These data revealed a significant correlation between the specific activity of 137Cs and the stable cesium content in all samples including caps and stipes, with correlation coefficients r of 0.956, 0.912, and 0.931, respectively, and all significant levels P < 0.01. The ratios of the specific activity of 137Cs to stable Cs content varied from 2.09 Bq/kg to 20.1 Bq/kg (dry weight), with an average of 10.7 Bq/kg (dry weight). Conclusions:Wild edible fungi fail to distinguish between 137Cs and stable cesium when absorbing Cs elements from their growing substrates. Furthermore, there is a strong correlation between the specific activity of 137Cs and stable Cs content. In the case of exogenous 137Cs contamination, the ratio of the specific activity of 137Cs and stable Cs content will significantly change. Therefore, an increase in the ratio can be used as a reference for identifying 137Cs contamination events.

Objective:To explore the applicability of critical statistical measures Z, Z′, Zeta ( ζ), and En value in comparative capability assessments by analyzing the data from nationwide radiological health technology institutions from 2020 to 2023, aiming to provide a reference for further improving China′s comparative assessment method for verifying the γ-ray spectroscopy capability of radionuclides. Methods:Based on the nationwide analysis and comparison of γ-ray spectroscopy of radionuclides conducted annually by the National Institute for Radiological Protection, China CDC, the deviations between laboratory result and reference values were determined using the above-mentioned four statistical measures. Finally, the qualification rates of the γ-ray spectroscopy result from relevant institutions were assessed and analyzed.Results:The result indicate that the qualification rates of the Z value exceeded 85%, which might be inaccurate in some cases since it ignored the limitation of uncertainty. In contrast, the Z′ value yielded more scientific and representative result because it considered the uncertainty of reference values, and the inter-laboratory comparison qualification rate is above 95%. In the case of low uncertainty of the γ-ray spectroscopy result, the Zeta ( ζ) or En ratio exhibited relatively high sensitivity and, accordingly, relatively low qualification rates, indicating that this ratio may not comprehensively reflect the interlaboratory comparison result. Conclusions:The Z, Z′, Zeta ( ζ), and En values demonstrate their own advantages and limitations in assessing the capability of the γ-ray spectroscopy of radionuclides. For comparison projects involving multiple laboratories and complex measurement conditions, such as the nationwide verification of the capabilities of the γ-ray spectroscopy of radionuclides, it is feasible to combine the Z′ value with the Zeta ( ζ) or En ratio, with the former and the latter used to determine the qualified and excellent capability result, respectively. This enables the comprehensive assessment of the measurement and analysis capabilities of the γ-ray spectroscopy laboratories of radiological health technology institutions in China.

Objective:To investigate the role of mechanosensor Yes-associated protein 1 (YAP1) in urothelial cells in inducing bladder dysfunction in a partial bladder outlet obstruction (pBOO) model.Methods:Ten female C57BL/6 mice were included in this study and randomly divided into pBOO and sham groups based on body weight using a stratified pairing method, with 5 mice in each group. The pBOO group underwent proximal urethral ligation surgery, while the sham group underwent a sham operation. Two weeks after surgery, the urinary pattern was analyzed using the urine spot test. The significant increase in urine spot numbers indicated the successful establishment of the pBOO model. The mice were then sacrificed, and bladder tissues were weighed and stained with hematoxylin and eosin (HE) to observe morphological changes. The bladder urothelial layer was further isolated, and total cell proteins were extracted to detect the expression levels of YAP1 protein using Western blotting. Mouse immortalized bladder urothelial cells were divided into three experimental groups: the negative control (NC) group, which was treated with YAP1-NC lentivirus; the overexpression (OE) group, which was treated with YAP1-OE lentivirus to induce YAP1 protein overexpression; and the verteporfin treatment (VP) group, which was treated with verteporfin on the basis of the OE group. Real-time quantitative PCR and Western blotting were used to verify the transcription and expression levels of YAP1 protein, the co-transcriptional activator TEAD4 protein, and the phosphorylated protein DRP1-616 (at serine 616) of dynamin-related protein 1 (DRP1). An ATP detection kit was used to measure the ATP release concentration in the NC, OE, and VP groups. The interaction between YAP1 and TEAD4 was investigated using co-immunoprecipitation, and the expression of the mitochondrial marker translocase of the outer mitochondrial membrane 20 (Tom20) was observed using immunofluorescence staining.Results:The results of the urine spot test showed that the number of urine spots on the filter paper in the pBOO group was higher than that in the sham group within 6 hours [(283.0±9.1) spots vs. (3.7±0.3) spots, P<0.01], and the urine spots were scattered. The bladder wet weight in the pBOO group was significantly higher than that in the sham group [(105.70±6.84) mg vs. (22.33±1.20) mg, P<0.01]. Histological observations revealed reduced bladder mucosal folds and increased detrusor muscle thickness in the pBOO group. The expression of YAP1 protein in the bladder urothelial cells of the pBOO group was significantly upregulated compared to the sham group [(1.26±0.08) vs. (0.50±0.04), P<0.01]. In vitro experiments showed that compared to the NC group, the OE group had significantly increased expression of DRP1-616 [(0.94±0.05) vs. (0.33±0.01), P<0.01] and higher ATP release concentration [(24.45±0.16) μmol/mg vs. (19.67±0.42) μmol/mg, P<0.01]. In contrast, the VP group had significantly decreased expression of DRP1-616 [(0.29±0.04) vs. (0.94±0.05), P<0.01] and lower ATP release concentration [(10.55±0.01) μmol/mg vs. (24.45±0.16) μmol/mg, P<0.01] compared to the OE group. Co-immunoprecipitation experiments using YAP1 and TEAD4 antibodies showed that YAP1 and TEAD4 proteins could interact and form a transcriptional complex to regulate ATP release. Immunofluorescence staining revealed increased expression of Tom20 in the OE group compared to the NC group [(104.20±3.28) vs. (74.51±3.87), P<0.01]. Conclusions:In the pBOO-induced bladder dysfunction model, YAP1 is highly expressed in urothelial cells. YAP1 forms a transcriptional complex with TEAD4 to regulate ATP release by promoting mitochondrial fission via DRP1-616 expression, which is a key mechanism underlying pBOO-induced bladder dysfunction.

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

Objective:To compare the efficacy of the transverse process-lateral pedicle approach and curved vertebroplasty in the treatment of osteoporotic vertebral compression fracture (OVCF).Methods:A retrospective cohort study was conducted to analyze the clinical data of 66 patients with OVCF admitted to the Second People′s Hospital of Hefei from December 2021 to June 2023, including 9 males and 57 females aged 60-89 years [(75.6±7.5)years]. The injured segments included T 11 in 17 patients, T 12 in 17, L 1 in 17, and L 2 in 15. Among them, 33 patients underwent vertebroplasty via the transverse process-lateral pedicle approach (lateral approach group), while other 33 patients underwent curved vertebroplasty (curved group). The surgical duration, number of X-ray fluoroscopy, bone cement injection volume, and length of hospital stay were compared between the two groups. Additionally, the restoration efficiency of vertebral height and the correction degree of spinal scoliosis Cobb angle at 2 days postoperatively were compared between the two groups. The changes in serum levels of stress factors including noradrenaline, adrenaline, and cortisol preoperatively and at 2 days postoperatively, the visual analogue scale (VAS) and Oswestry disability index (ODI) preoperatively, at 2 days, 6 months postoperatively, and at the last follow-up were compared between the two groups. The incidence of complications was assessed in the two groups. Results:All the patients were followed up for 12-14 months [(13.2±0.5)months]. The surgical duration and number of X-ray fluoroscopy in the lateral approach group were (30.9±4.1)minutes and (5.9±3.3)times, which were significantly lower than (35.8±3.9)minutes and (9.9±4.4)times in the curved group ( P<0.01). There were no statistically significant differences between the two groups in terms of bone cement injection volume, length of hospital stay, restoration efficiency of vertebral height at 2 days postoperatively, or the correction degree of spinal scoliosis Cobb angle ( P>0.05). The levels of noradrenaline, adrenaline, and cortisol at 2 days postoperatively were (57.3±4.8)ng/ml, (49.9±4.2)ng/ml, (159.3±20.5)nmol/L in the lateral approach group, and (64.3±4.5)ng/ml, (58.3±4.4)ng/ml, (183.5±21.2)nmol/L in the curved group, which were all significantly increased compared with those preoperatively [(42.3±3.5)ng/ml, (38.5±2.8)ng/ml, (128.4±12.3)nmol/L in the lateral approach group and (42.0±3.5)ng/ml, (39.0±3.0)ng/ml, (128.5±12.3)nmol/L in the curved group] ( P<0.01). There were no significant differences between the two groups in terms of the levels of noradrenaline, adrenaline, and cortisol preoperatively ( P>0.05). The levels of noradrenaline, adrenaline, and cortisol at 2 days postoperatively in the lateral approach group were significantly lower than those in the curved group ( P<0.01). The VAS scores for low back pain in the lateral approach group and the curved group were 3(2, 5)points and 5(3, 6)points at 2 days postoperatively, 3(2, 4)points and 3(2, 4)points at 6 months postoperatively, and 2(2, 3)points and 2(2, 4)points at the last follow-up, which were all significantly lower than those preoperatively [7(7, 9)points and 8(6, 9)points] ( P<0.05). Moreover, the VAS scores for low back pain were further decreased over time postoperatively ( P<0.05). The ODI values in the lateral approach group and curved group were (33.4±4.4)% and (33.7±4.3)% at 2 days postoperatively, (23.8±1.6)% and (23.8±1.7)% at 6 months postoperatively, and (15.6±0.9)% and (15.6±0.9)% at the last follow-up, which were all significantly lower than (67.4±4.3)% and (67.5±4.3)% preoperatively ( P<0.05). Moreover, the ODI values were further decreased over time postoperatively ( P<0.05). There were no significant differences between the two groups in terms of the VAS scores for low back pain or ODI values preoperatively, at 2 days, 6 months postoperatively or at the last follow-up ( P>0.05). The complication rate was 12.1% (4/33) in the lateral approach group, which was significantly lower than 51.5% (17/33) in the curved group ( P<0.05). Conclusion:Although both the transverse process-lateral pedicle approach vertebroplasty and the curved vertebroplasty can achieve good therapeutic effects in the treatment of OVCF, the former has shorter surgical duration, fewer times of X-ray fluoroscopy, lower trauma stress levels at 2 days postoperatively, and fewer complications.

BACKGROUND: The purpose of this study was to evaluate the safety and efficacy of subsequent radiotherapy (RT) following first-line treatment with durvalumab plus chemotherapy in patients with extensive-stage small cell lung cancer (ES-SCLC). METHODS: A total of 122 patients with ES-SCLC from three hospitals during July 2019 to December 2021 were retrospectively analyzed. Inverse probability of treatment weighting (IPTW) analysis was performed to address potential confounding factors. The primary focus of our evaluation was to assess the impact of RT on progression-free survival (PFS) and overall survival (OS). RESULTS: After IPTW analysis, 49 patients received durvalumab plus platinum-etoposide (EP) chemotherapy followed by RT (Durva + EP + RT) and 72 patients received immunochemotherapy (Durva + EP). The median OS was 17.2 months vs . 12.3 months (hazard ratio [HR]: 0.38, 95% confidence interval [CI]: 0.17-0.85, P = 0.020), and the median PFS was 8.9 months vs . 5.9 months (HR: 0.56, 95% CI: 0.32-0.97, P = 0.030) in Durva + EP + RT and Durva + EP groups, respectively. Thoracic radiation therapy (TRT) resulted in longer OS (17.2 months vs . 14.7 months) and PFS (9.1 months vs . 7.2 months) compared to RT directed to other metastatic sites. Among patients with oligo-metastasis, RT also showed significant benefits, with a median OS of 17.4 months vs . 13.7 months and median PFS of 9.8 months vs . 5.9 months compared to no RT. Continuous durvalumab treatment beyond progression (TBP) prolonged OS compared to patients without TBP, in both the Durva + EP + RT (NA vs . 15.8 months, HR: 0.48, 95% CI: 0.14-1.63, P = 0.238) and Durva + EP groups (12.3 months vs . 4.3 months, HR: 0.29, 95% CI: 0.10-0.81, P = 0.018). Grade 3 or 4 adverse events occurred in 13 (26.5%) and 13 (18.1%) patients, respectively, in the two groups; pneumonitis was mostly low-grade. CONCLUSION Addition of RT after first-line immunochemotherapy significantly improved survival outcomes with manageable toxicity in ES-SCLC.
