ObjectiveTo investigate the associations of multiple glycolipid metabolic indicators and their cumulative abnormality burden with incident colorectal cancer risk in a general population-based prospective cohort, and to examine the mediating role of glycolipid metabolic abnormalities in the relationships between smoking, alcohol consumption, physical activity, and colorectal cancer incidence. MethodsA total of 17 897 eligible participants recruited from the Taizhou Cohort between 2011 and 2014 were included. Cox proportional hazards regression models were used to assess the associations of conventional and derived glycolipid indicators, as well as a glycolipid abnormality index constructed from total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, fasting plasma glucose, and insulin, with incident colorectal cancer risk. Restricted cubic spline models were applied to evaluate dose-response relationships for major indicators. Receiver operating characteristic curves were generated to compare predictive performance across indicators. Mediation analyses were conducted to assess the mediating effects of the glycolipid abnormality index on the associations of smoking, alcohol consumption, and physical activity with colorectal cancer incidence. ResultsDuring a median follow-up of 11.2 years, 102 incident colorectal cancer cases were identified, with an incidence density of 51.2 per 100 000 person-years. After adjustment for potential confounders, Cox proportional hazards regression analyses showed that decreased high-density lipoprotein cholesterol was associated with a 1.74-fold higher risk of colorectal cancer (HR=1.74, 95%CI: 1.03‒2.95), elevated low-density lipoprotein cholesterol was associated with a 1.78-fold higher risk (HR=1.78, 95%CI: 1.05‒3.02), and abnormal fasting plasma glucose was associated with a 1.86-fold higher risk (HR=1.86, 95%CI: 1.15‒3.02). Triglycerides and fasting plasma glucose showed an approximately linear increasing association with colorectal cancer risk in multivariable restricted cubic spline models. The glycolipid abnormality index showed a clear gradient association with colorectal cancer risk; participants with three or more abnormal indicators had a 3.08-fold higher risk than those without abnormalities (HR=3.08, 95%CI: 1.60‒5.92). The area under the curve was 0.795, higher than that of individual glycolipid indicators and other combined indices, and gender-stratified analyses showed generally consistent patterns. Glycolipid metabolic abnormalities partially mediated the associations of smoking, alcohol consumption, and physical activity with colorectal cancer incidence, with mediation proportions of 8.33%, 9.45%, and 9.04%, respectively. ConclusionGlycolipid metabolic abnormalities are associated with an increased risk of incident colorectal cancer. The glycolipid abnormality index shows an increasing relationship with colorectal cancer risk and demonstrates better discrimination, and it partially mediates the associations of smoking, alcohol consumption, and physical activity with colorectal cancer incidence in the overall population.

Radiation-induced thrombocytopenia (RIT) faces a perplexing challenge in the clinical treatment of cancer patients, and current therapeutic approaches are inadequate in the clinical settings. In this research, oxymatrine, a new molecule capable of healing RIT was screened out, and the underlying regulatory mechanism associated with magakaryocyte (MK) differentiation and thrombopoiesis was demonstrated. The capacity of oxymatrine to induce MK differentiation was verified in K-562 and Meg-01 cells in vitro. The ability to induce thrombopoiesis was subsequently demonstrated in Tg (cd41:enhanced green fluorescent protein (eGFP)) zebrafish and RIT model mice. In addition, we carried out network pharmacological prediction, drug affinity responsive target stability assay (DARTS) and cellular thermal shift assay (CETSA) analyses to explore the potential targets of oxymatrine. Moreover, the pathway underlying the effects of oxymatrine was determined by Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses, Western blot (WB), and immunofluorescence. Oxymatrine markedly promoted MK differentiation and maturation in vitro. Moreover, oxymatrine induced thrombopoiesis in Tg (cd41:eGFP) zebrafish and accelerated thrombopoiesis and platelet function recovery in RIT model mice. Mechanistically, oxymatrine directly binds to toll-like receptor 2 (TLR2) and further regulates the downstream pathway stimulator of interferon genes (STING)/nuclear factor-kappaB (NF-κB), which can be blocked by C29 and C-176, which are specific inhibitors of TLR2 and STING, respectively. Taken together, we demonstrated that oxymatrine, a novel TLR2 agonist, plays a critical role in accelerating MK differentiation and thrombopoiesis via the STING/NF-κB axis, suggesting that oxymatrine is a promising candidate for RIT therapy.

BACKGROUND: Acupuncture therapy provides a complementary and alternative approach to treating major depressive disorder (MDD), but its efficacy and safety have still not been comprehensively assessed. Recently published systematic reviews remain confusing and inconclusive. OBJECTIVE: This systematic review evaluated the efficacy and safety of acupuncture therapy alone or combined with antidepressants for adult patients with mild and moderate MDD. SEARCH STRATEGY: Chinese Biomedical Literature Database, China National Knowledge Infrastructure Database, Wanfang Database, Chinese Science and Technology Journal Database, PubMed, Embase, and Cochrane Library were searched from their inceptions to March 2025. INCLUSION CRITERIA: Randomized controlled trials that compared acupuncture therapy with antidepressants, or acupuncture therapy plus antidepressants with acupuncture therapy or antidepressants for adult patients with mild and moderate MDD were included. DATA EXTRACTION AND ANALYSIS: Five reviewers independently extracted data from original literature using a standardized form, and the data were verified by two reviewers to ensure accuracy. Statistical meta-analyses, publication bias analyses, and subgroup analyses were performed by using Review Manager 5.3 software. The Grading of Recommendations Assessment, Development, and Evaluation approach was used to assess the certainty of the evidence. RESULTS: A total of 60 eligible studies including 4675 participants were included. Low-certainty evidence showed that compared with antidepressants, acupuncture therapy (standardized mean difference [SMD] = -0.57; 95% confidence interval [CI] = [-0.87, -0.27]; I² = 86%; P = 0.006) or acupuncture therapy plus antidepressants (SMD = -1.00; 95% CI = [-1.18, -0.81]; I² = 77%; P < 0.00001) may reduce the severity of depression at the end of treatment. Low-certainty evidence indicated that compared with acupuncture therapy alone, acupuncture therapy plus antidepressants slightly reduced the severity of depression at the end of treatment (SMD = -0.38; 95% CI = [-0.61, -0.14]; I² = 18%; P = 0.002). Similar results were also found for acupuncture's relief of insomnia. The reported adverse effects of acupuncture therapy were mild and transient. For most of the subgroup analyses, acupuncture type, scale type, and the course of treatment did not show a significant relative effect. CONCLUSION Acupuncture therapy may provide antidepressant effects and relieve insomnia with mild adverse effects for adult patients with mild and moderate MDD. But the certainty of evidence was very low. More high-quality, well designed, large-scale studies with long-term follow-up are needed in the future.

Phages, as obligate bacterial and archaeal parasites, constitute a virus group of paramount ecological significance due to their exceptional abundance and genetic diversity. These biological entities serve as critical regulators in Earth's ecosystems, driving biogeochemical cycles, energy fluxes, and ecosystem services across terrestrial and marine environments. Within soil microbiomes, phages function as microbial "dark matter," maintaining the soil-plant system balance through precise modulation of the microbial community structure and functional dynamics. Despite the growing research interests in soil phages in recent years, the proportion of such studies in environmental virology remains disproportionately low, which is primarily attributed to researchers' limited familiarity with the research methodologies for phage microecology, incomplete technical frameworks, and inherent challenges posed by soil environmental complexity. To address these challenges, this review synthesizes cutting-edge methodologies for soil phage investigation from four aspects: (1) tangential flow filtration (TFF)-based phage enrichment strategies; (2) integrated quantification approaches combining double-layer agar plating, epifluorescence microscopy, and flow cytometry; (3) multi-omics analytical pipelines leveraging metagenomics and viromics datasets; and (4) computational frameworks merging machine learning algorithms with eco-evolutionary theory for deciphering phage-host interaction networks. Through comparative analysis of methodological principles, technical merits, and application scopes, we establish a comprehensive workflow for soil phage research. Future research in this field should prioritize: (1) construction of soil phage resource libraries, (2) exploration of RNA phages based on transcriptomes, (3) functional characterization of unknown genes, and (4) deep integration and interaction validation of multi-omics data. This systematic methodological synthesis provides critical technical references for addressing fundamental challenges in characterizing soil phages regarding the community structure, functional potential, and interaction mechanisms with hosts.

Objective:To summarize the clinicopathologic characteristics of malignant hypertension (MHT) patients with acute kidney injury (AKI) and application of renin-angiotensin-aldosterone system inhibitor (RAASi).Methods:It was a retrospective cohort study. The adult patients with MHT and AKI admitted to Peking University First Hospital from January 1, 2012 to July 14, 2022. The patients were categorized into RAASi group and non-RAASi group based on RAASi administration from AKI onset to discharge. The clinicopathological data between the two groups were compared, and application of RAASi was analyzed.Results:A total of 179 patients were enrolled with age of 31 (26, 37) years and 148 males (82.7%). Ninety-five patients (53.1%) received dialysis treatment. The common causes of MHT were essential hypertension (125 patients, 69.8%), renal hypertension (39 patients, 21.8%) and endocrine hypertension (7 patients, 3.9%). AKI severity distribution showed 41 patients (22.9%) in stage 1, 1 patient (0.5%) in stage 2 and 137 patients (76.5%) in stage 3. Among MHT patients, 94 patients (52.5%) had been treated with RAASi before AKI, and 13 patients (7.3%) discontinued RAASi after AKI. Among 85 patients (47.5%) without receiving RAASi treatment before AKI, 68 new patients (38.0%) received RAASi treatment after AKI, and 40 patients (22.3%) were treated with the support of dialysis. Compared with non-RAASI group ( n=30), proportions of chronic kidney disease ( χ2=6.324, P=0.012) and post-AKI hyperkalemia ( χ2=4.048, P=0.044) in RAASi group ( n=149) were lower, and the proportion of dialysis treatment ( χ2=5.638, P=0.018), admission diastolic blood pressure ( Z=-3.609, P<0.001) and maximum diastolic blood pressure during hospitalization ( Z=-1.978, P=0.048) were higher. There were no statistically significant differences in the rates of target blood pressure control and renal function recovery between the two groups during hospitalization (all P>0.05). During hospitalization, 64 patients received renal biopsies, of which 50 patients (78.1%) had typical MHT vascular lesions such as "onion skin" in renal arterioles. Twenty-seven patients (42.2%) were complicated with glomerular diseases, and IgA nephropathy was the most common type (85.2%, 23/27). The proportions of glomerular ischemia and sclerosis, endothelial cell proliferation and acute renal tubular injury in RAASi group ( n=54) were lower than those in non-RAASi group ( n=10), and proportions of thrombosis and "onion skin" change were higher than those in RAASi group ( n=10), but the differences were not statistically significant (all P>0.05). Renal function recovery occurred in 47 patients (26.3%) by discharge. Among 95 dialysis patients, 26 patients (27.4%) achieved dialysis independence at discharge. Conclusions:MHT patients with AKI exhibit severe renal pathology and short-term poor prognosis. RAASi is primarily prescribed to those with relatively better kidney function or those receiving dialysis support.

Objective:To investigate the serum sodium level and its fluctuation in patients with hospitalized acquired acute kidney injury (AKI) and explore their impacts on in-hospital mortality.Methods:It was a single-center retrospective study. The adult patients developing hospital-acquired AKI and receiving at least twice serum sodium tests admitted to Peking University First Hospital from January 1, 2018, to December 31, 2020 were included. Dysnatremia included hyponatremia (< 135 mmol/L) and hypernatremia (>145 mmol/L). The patients were divided into hyponatremia group, normal serum sodium group and hypernatremia group, and the differences of clinical data among the three groups were compared. The fluctuation of serum sodium level was evaluated by coefficient of variation. A restricted cubic spline was applied to investigate the association between serum sodium level at AKI onset and mortality. Poisson regression analysis was used to explore the mortality risk of dysnatremia at AKI onset, dysnatremia at admission, and coefficient of variation of serum sodium, respectively.Results:Among the enrolled 1 475 AKI patients, the age was 66.0 (55.0, 78.0) years, and 850 patients (57.6%) were males. The estimated glomerular filtration rate was 77.3 (50.4, 97.6) ml·min -1·(1.73 m 2) -1. The time from admission to AKI onset was 8 (4, 15) days. The incidence of hyponatremia and hypernatremia at admission were 19.6% (289/1 475) and 2.6% (39/1 475), respectively, while the incidence at AKI onset was 24.0% (354/1 475) and 12.7% (188/1 475), respectively. There was statistically significant difference in terms of age, the initial classification distribution of AKI, serum sodium at admission, serum sodium at the occurrence of AKI, the lowest serum sodium at hospitalization, the highest serum sodium at hospitalization, the coefficient of variation of serum sodium, and the proportions of heart failure, stroke, disseminated intravascular coagulation, sepsis, acute respiratory distress syndrome, shock, prerenal causes, circle diuretics and aldosterone antagonists among hyponatremia group, normal serum sodium group and hypernatremia group (all P<0.05). The restricted cubic spline analysis showed a "U"-shaped correlation between serum sodium level at AKI onset and in-hospital mortality. Poisson regression analysis showed that after adjusting for age, gender, number of chronic comorbidities, initial classification of AKI, basal estimated glomerular filtration rate and number of acute disease state, with normal serum sodium as the reference, hyponatremia ( RR=1.56, 95% CI 1.14-2.13) and hypernatremia ( RR=1.71, 95% CI 1.23-2.39) at AKI onset were correlated with an increased risk of in-hospital mortality. Hyponatremia at admission was correlated with an increased risk of in-hospital mortality ( RR=2.13, 95% CI 1.62-2.79), while there was no statistically significant association between hypernatremia and in-hospital mortality ( RR=1.22, 95% CI 0.62-2.44). After further adjusting serum sodium levels at admission and at the occurrence of AKI, the coefficient of variation of serum sodium level was still correlated with an increased risk of in-hospital mortality ( RR=1.23, 95% CI 1.14-1.33). Conclusions:Dysnatremia is common in patients with hospital-acquired AKI. The serum sodium level at AKI onset is correlated with in-hospital death in a "U" shape. Dysnatremia and serum sodium fluctuation are associated with an increased risk of in-hospital mortality.

Objective:To compare the diagnostic efficacy of 68Ga-prostate-specific membrane antigen (PSMA)-617 PET/CT and multiparametric magnetic resonance imaging (mpMRI) in detecting extraprostatic extension (EPE) and seminal vesicle invasion (SVI) in prostate cancer. Methods:A retrospective analysis was conducted on the clinical data of 113 patients with localized prostate cancer who underwent both 68Ga-PSMA-617 PET/CT and mpMRI at Xiangya Hospital, Central South University, from May 2018 to May 2024 prior to radical prostatectomy (RP). The median age of the patients was 66.0 (61.3, 71.0) years old, with a median body mass index of 28.86 (19.01, 24.77) kg/m 2, and a median prostate-specific antigen (PSA) level of 13.50(9.26, 21.99) ng/ml. The pathological results after RP were used as the gold standard to compare the sensitivity, specificity, positive predictive value, and negative predictive value of the two imaging modalities in diagnosing EPE and SVI. Additionally, the diagnostic value of combining both imaging modalities was explored, employing a parallel strategy where a positive result from either modality was deemed positive, and only when both tests were negative was the result considered negative. Results:Pathological results after RP indicated EPE in 46 cases (40.71%) and SVI in 11 cases (9.70%). In diagnosing EPE, the sensitivity, specificity, positive predictive value, and negative predictive value of 68Ga-PSMA-617 PET/CT were 17.39% (8/46), 97.01% (65/67), 80.00% (8/10), and 63.11% (65/103), respectively, while for mpMRI they were 34.78% (16/46), 83.58% (56/67), 59.26% (16/27), and 65.12% (56/86), respectively. The sensitivity of mpMRI was significantly higher than that of 68Ga-PSMA-617 PET/CT ( P=0.048), while the specificity was the opposite ( P=0.008). When combining both imaging modalities, the sensitivity, specificity, positive predictive value, and negative predictive value were 45.65% (21/46), 80.60% (54/67), 61.76% (21/34), and 68.35% (54/79), respectively. In diagnosing SVI, the sensitivity, specificity, positive predictive value, and negative predictive value of 68Ga-PSMA-617 PET/CT were 27.27% (3/11), 96.08% (98/102), 42.86% (3/7), and 92.45% (98/106), respectively, while for mpMRI they were 36.36% (4/11), 88.24% (90/102), 25.00% (4/16), and 92.78% (90/97), respectively. The specificity of 68Ga-PSMA-617 PET/CT was significantly higher than that of mpMRI ( P=0.033). When combining both imaging modalities, the sensitivity, specificity, positive predictive value, and negative predictive value were 45.45% (5/11), 85.29% (87/102), 25.00% (5/20), and 93.55% (87/93), respectively. Conclusions:mpMRI has higher sensitivity in diagnosing EPE and SVI in prostate cancer, while 68Ga-PSMA-617 PET/CT shows higher specificity. The combined use of both imaging modalities can increase diagnostic sensitivity but may reduce specificity. PSMA PET/MRI may be a more accurate diagnostic tool for discerning EPE and SVI.

Objective:To compare the dose-response effects of single-fraction ultra-high dose rate (FLASH) and conventional dose rate (CONV) whole abdominal irradiation (WAI) with X-rays on acute radiation-induced intestinal injury in mice, in order to identify optimal dose parameters and potential mechanisms.Methods:A total of 186 male C57BL/6J mice were randomly assigned to a non-irradiation group ( n=6), FLASH irradiation groups ( n=90), and CONV irradiation groups ( n=90). Acute radiation-induced intestinal injury models were established using single-fraction WAI with 11, 12, 13, 14, and 15 Gy X-rays (200 Gy/s for FLASH and 4 Gy/min for CONV). Changes in body weight, stool characteristics, and disease activity index (DAI) scores were assessed at 9 d post-irradiation. At 7 d post-irradiation at 11, 12, and 13 Gy, the intestines were collected for macroscopic examination and length measurement. The small intestine was selected for HE staining and quantitative analysis of intestinal crypt number and mucosal epithelial thickness. The survival of mice was assessed at 15 d post-WAI across all dose groups. Results:After single-fraction WAI at 11, 12, and 13 Gy, the body weight was higher in the FLASH group than that in the CONV group ( t=10.17, 12.65, 10.16, P<0.05). The DAI scores for the FLASH group were 1.00±1.10, 3.17±0.75, and 2.83±1.17, respectively, which were lower than those of the CONV group (4.33±0.52, 7.00±0.00, 8.60±0.55; t=8.70, 11.71, 14.99, P<0.05). However, after WAI at 14 Gy and 15 Gy, there were no significant differences in body weight and DAI between the FLASH group and the CONV group ( P>0.05). At 7 d after single-fraction WAI at 11, 12, and 13 Gy, mice in the FLASH group exhibited less intestinal congestion, edema, and shortening compared with the CONV group. The difference between the FLASH and CONV groups were statistically significant in small intestine length at 11 and 13 Gy ( t=4.42, 3.78, P<0.05), and in colorectal length at 11 and 12 Gy ( t=3.97, 3.12, P<0.05). Small intestine HE staining revealed superior preservation of intestinal architecture in the FLASH group compared with the CONV group, characterized by longer villi, increased crypt numbers, thicker mucosal epithelium, and enhanced structural integrity. The differences in crypt number and mucosal epithelial thickness were statistically significant ( tcrypt=13.10, 23.80, 11.90; tmucosal=5.75, 2.64, 7.74; P<0.05). At 15 d post-irradiation, the survival rate in the 15 Gy FLASH group was higher than that in the CONV group (50% vs. 10%, χ2=5.39, P<0.05), with a median survival extension of 6 d ( HR=0.340, 95% CI: 0.115 4-0.999 9). No significant survival differences were observed between the FLASH group and the CONV group at 11, 12, 13, and 14 Gy ( P>0.05). Conclusions:FLASH irradiation significantly alleviated acute radiation-induced intestinal injury from medium single-fraction WAI with 11, 12, and 13 Gy X-rays compared with CONV irradiation, and showed potential to improve mouse survival after single-fraction WAI at 15 Gy. This effect is likely associated with the preservation of intestinal crypts and exhibits a dose-dependent relationship.

Objective:To analyze the human immunodeficiency virus (HIV) screening status and the resulting residual risk (RR) among blood donors across 17 provincial blood centers in China.Methods:This study used a cross-sectional study. Data on HIV infection markers per 100 000 first-time donors (FD) and repeat donors (RD) from January 2015 to December 2024 were extracted from the National Blood Establishment Performance Comparison Information Management System. Questionnaires were used to collect each center′s HIV screening strategy, algorithm, serological test (ST) kit manufacturers, gray-zone setting for ST, and nucleic acid test (NAT) modality, method, and platform. The incidence-window-period model was used to calculate the residual risk for first-time donors (RR FD), repeat donors (RR RD), and total donors (RR TD) at each center. Horizontal and vertical analysis of RR FD, RR RD, and RR TD across centers and years were performed. Results:All 17 centers applied the same HIV screening strategy which was two rounds of ST followed by one round of NAT. Eight of them operated a single screening algorithm, six employed two algorithms and three used three. Eleven centers used both imported and domestic ST kits, five relied on domestic ST kits only, and one used imported ST kits only, while four centers never set a grey zone for ST throughout the decade. For NAT modalities, eight centers adopted both individual nucleic acid test (ID-NAT) and minipool nucleic acid test (MP-NAT), eight used MP-NAT only and one used ID-NAT only. Seven centers combined transcription mediated amplification (TMA) and polymerase chain reaction (PCR), nine used PCR only and one used TMA only, and fourteen centers ran both imported and domestic NAT systems, two used imported systems only and one used a domestic system only. Over the ten-year period, the mean RR FD across the centers ranged from 2.22 to 12.33 per 10 6 person-years, RR RD from 0.83 to 3.29 per 10 6 person-years and RR TD from 1.59 to 9.29 per 10 6 person-years, with center Z4 consistently showing the lowest values for all three metrics and center U4 recording the highest RR FD and RR TD, while center D2 had the highest RR RD. In 2024 compared with 2015, eleven centers achieved a lower RR FD and ten centers achieved lower RR RD and RR TD. The RR FD and RR TD of centers W2 and U4 displayed pronounced fluctuations and an upward trend in recent years. Conclusions:The 17 provincial blood centers maintain consistent HIV screening strategies, while demonstrating variations in screening algorithm, ST kit manufacturers, NAT modalities, methods, and platform. And the RR FD, RR RD, and RR TD differ across centers. Although most centers show declining trend in RR over the ten-year period, some centers exhibite data fluctuations with a rising trend, suggesting potential for further optimization of HIV screening protocols.
