Microbial communities such as those residing in the human gut are highly diverse and complex, and many with important implications for health and diseases. The effects and functions of these microbial communities are determined not only by their species compositions and diversities but also by the dynamic intra- and inter-cellular states at the transcriptional level. Powerful and scalable technologies capable of acquiring single-microbe-resolution RNA sequencing information in order to achieve a comprehensive understanding of complex microbial communities together with their hosts are therefore utterly needed. Here we report the development and utilization of a droplet-based smRNA-seq (single-microbe RNA sequencing) method capable of identifying large species varieties in human samples, which we name smRandom-seq2. Together with a triple-module computational pipeline designed for the bacteria and bacteriophage sequencing data by smRandom-seq2 in four human gut samples, we established a single-cell level bacterial transcriptional landscape of human gut microbiome, which included 29,742 single microbes and 329 unique species. Distinct adaptive response states among species in Prevotella and Roseburia genera and intrinsic adaptive strategy heterogeneity in Phascolarctobacterium succinatutens were uncovered. Additionally, we identified hundreds of novel host-phage transcriptional activity associations in the human gut microbiome. Our results indicated that smRandom-seq2 is a high-throughput and high-resolution smRNA-seq technique that is highly adaptable to complex microbial communities in real-world situations and promises new perspectives in the understanding of human microbiomes.

Acetaminophen (APAP) is the primary cause of drug-induced acute liver failure. Ovarian tumor deubiquitinase 6A (OTUD6A), a recently discovered deubiquitinase of the OTU family, has been primarily studied in tumor contexts. However, its role in APAP-induced liver injury (AILI) remains unclear. Therefore, this study aimed to investigate the involvement of OTUD6A in the pathogenesis of AILI. Our findings demonstrated a substantial upregulation of OTUD6A in both the liver tissue and isolated hepatocytes of mice following APAP stimulation. OTUD6A knockout exacerbated APAP-induced inflammation, hepatocyte necrosis, and liver injury, whereas OTUD6A overexpression alleviated these pathologies. Mechanistically, OTUD6A directly interacted with the enhancer of zeste homolog 2 (EZH2) and selectively removed K48-linked polyubiquitin chains from EZH2, enhancing its stability. This resulted in increased protein levels of EZH2 and H3K27me3, as well as reduced endoplasmic reticulum (ER) stress and cell death in hepatocytes. Collectively, our research uncovers a novel role for OTUD6A in mitigating APAP-induced liver injury by promoting EZH2 stabilization.

Objective To evaluate the baseline characteristics and short-term safety of lecanemab in treatment of Alzheimer's disease(AD)in Chinese patients in a real-world study.Methods A mul-ticenter,retrospective,observational study was conducted on 646 AD patients who were continu-ously recruited and receved of lecanemab therapy in 84 medical centers from June 26,2024 to March 1,2025.Their clinical data,including baseline Mini-mental state examination(MMSE)score and clinical dementia rating(CDR)score before and after treatment,were collected,and the CDR-global score(CDR-GS)and CDR-sum of box score were calculated.The incidences of infu-sion-related reactions(IRR)and amyloid-related imaging abnormalities(ARIA),including ARIA with edema and effusion(ARIA-E)and ARIA with hemosiderin deposit(ARIA-H)within 3 months of treatment were observed and recorded.Apolipoprotein E(ApoE)genetic test was per-formed on 454 patients.Baseline characteristics and short-term safety of the patients were ana-lyzed.Results There were 301 patients(46.59％)having a baseline CDR-GS score of 0.5 and 345(53.41％)patients had a CDR score of 1.In the 454 patients receiving genetic test,the ApoEε4 carriers accounted for 31.27％(202 cases),including 17 cases of ApoEε4 homozygous carriers(8.42％).The incidence of IRR was 4.95％(32/646),which mainly occurred during the first infu-sion(90.63％,29/32),and there were 96.88％(31/32)of mild and 3.13％(1/32)of moderate IRR,with main manifestations of fever,dizziness,vomiting,etc.Sixteen patients(2.48％)experienced ARIA,including 5(31.25％)ARIA-E,10(62.50％)ARIA-H,and 1(6.25％)ARIA-E and ARIA-H.For the 5 patients with ARIA-E,2 were symptomatic,and in terms of radiographic severity,3 cases were mild and 2 cases were moderate ARIA-E.In the 10 patients with ARIA-H,all of them had no clinical symptoms,and in terms of radiographic severity,6 had mild and 4 had moderate ARIA-H.Among the 17 ApoEε4 homozygous patients,only one patient(5.88％)experi-enced ARIA-H with a moderate radiographic severity.Multivariate analysis showed that age in-creased the trend of ARIA risk,but no statistical difference was observed(P=0.056).Conclusion In this real-world study in China,AD patients receiving lecanemab treatment have the characteris-tics of being younger in age but higher disease severity.Short-term follow-up data suggest that lecanemab has good safety.

Objective To observe the effect of postoperative local injection of platelet-rich plasma(PRP)on patients'early inflammatory response and functional recovery in ankle fractures with lower tibiofibular injuries.Methods Fifty ankle fracture patients with lower tibiofibular injuries admitted to our hospital from January 2017 to December 2022 with postoperative local injection of PRP were selected as the PRP group,and 50 ankle fracture patients with lower tibiofibular injuries undergoing surgical treatment with ligament repair protocols in the same time period with their matched gender and age were selected as the conventional group.We compared the postoperative conditions,postoperative 3 d swelling,postoperative pain visual analogue(VAS)scores and levels of platelet-derived growth factor(PDGF),transforming growth factor β1(TGF-β1),and inflammatory mediators in the two groups,and counted the 24-week postoperative good rate,ankle plantarflexion-dorsiflexion mobility,the quality of the restoration,and the complications in the two groups.Results The swelling grading in the PRP group was lower than that in the conventional group(28 cases of grade Ⅰ,20 cases of grade Ⅱ,and 2 cases of gradeⅢ)in the 3 d postoperative period(15 cases of grade Ⅰ,23 cases of grade Ⅱ,and 12 cases of gradeⅢ),and the VAS scores in the 3 d and 7 d postoperative period[(3.24±0.61)and(2.40±0.42)points]were lower than those in the conventional group[(3.78±0.74)and(2.96±0.55)],and the lower limb weight-bearing activity time(4.01±0.65)weeks,fracture healing time(3.05±0.42)months,and postoperative return to normal work time(3.17±0.47)months were shorter than those in the conventional group[weight-bearing activity time of lower limbs(4.29±0.74)weeks,fracture healing time(3.23±0.48)months,and postoperative return to normal work time(3.40±0.59)months].While the operation time(106.53±19.77)min,number of intraoperative fluoroscopies(14.47±3.23)times,and intraoperative blood loss(84.07±25.60)ml were not statistically different from those of the conventional group[operation time(108.20±18.41)min,number of intraoperative fluoroscopies(14.53±3.06)times,and intraoperative blood loss(86.23±22.17)ml]were not statistically different when compared(P＞0.05).There was no statistical difference in the comparison of preoperative inflammatory mediators,PDGF,and TGF-β1 between the two groups(P＞0.05).In both groups,PDGF was higher and interleukin-6(IL-6),TGF-β1,C-reactive protein(CRP),and tumour necrosis factor-α(TNF-α)were lower at 12 weeks postoperatively compared with the preoperative period(P＜0.05).In the PRP group,the postoperative PDGF was higher than that of the conventional group,and the inflammatory mediators and TGF-β1 were lower than those of the conventional group at 12 weeks postoperatively(P＜0.05).In the PRP group,the postoperative 24 week good rate and ankle plantarflexion-dorsiflexion mobility were higher than that of the conventional group,and the inferior tibiofibular coalition anterior spacing(ITFACS)and inferior tibiofibular coalition posterior spacing(ITFPCS)were lower than that of the conventional group,and there was no statistically significant difference in the rate of complications when comparing the rate with that of the conventional group(P＞0.05).Conclusion Local PRP injection combined with ligament repair protocol for treatment of ankle fractures with lower tibial fibula injuries accelerates patients'early functional recovery and improves the quality of anatomical repositioning,which may be related to the inhibition of inflammatory mediator release and the promotion of bone repair.

As a practical carrier for promoting the tiered diagnosis and treatment model, the medical consor-tium is of great significance for balancing medical resources and boosting medical service efficiency. The construction of medical consortiums not only improves the accessibility of high-quality medical resources for patients, but also enhances the diagnostic and treatment level of member units. Meanwhile, it provides space for the leading hospital to adjust the structure of diseases and improve the level of discipline construction. As the core of medical insurance payment reform, DRG, through indicators such as the case mix index(CMI) and the number of diagnosis related group (DRG), provides objective and quantified data support for case management and disease structure optimization, thus effectively guiding the rational allocation of medical resources and the adjustmentof diseases and surgical types within the medical consortium. Comprehensive use of DRG evaluation indicators can construct a multidimensional medical consortium construction evaluation system, provides a clear direction for medical consortium cooperation, thereby promoting the overall healthy and sustainable development of medical consortiums and achieving a win-win situation for all parties involved. This paper, based on the "1+5+1" medical consortium cooperation model centered around Peking Union Medical College Hospital, utilizes DRG indicators to analyze the benefits for patients, member hospitals, and the leading hospital during the medical consortium construction process, with the hope of providing reference for the construction of a medical consortium evaluation system.

To analyze the disease group structure and its trends in key departments of large public hospitals using diagnosis related group (DRG) data, explore the key points of intervention and optimization of disease groups in departments, and further promote the rational allocation of department resources.

The prevalence of Lyme disease in endogenous populations in Urumqi,Xinjiang was investigated.In total,795 serum samples were collected from residents of three townships in the surrounding area of Urumqi City from 2022 to 2023,which included 383 from Lucaogou Town,145 from Shuixigou Town,and,267 from Tori Township.Serum levels of IgG and IgM antibodies were screened with an enzyme linked immunosorbent assay(ELISA)and confirmed by western blot(WB)analysis.Clinical data of WB-positive indi-viduals were collected and comprehensive analysis was con-ducted for case diagnosis.The chi square test was used for statistical analysis of the results and the P＜0.05 was consid-ered statistically significant.In total,110(13.84％)of 795 samples were positive.The positivity rates was higher in females than males[16.26％(73/449)vs.10.69％(37/346),x2=5.076,P=0.024],while there was no significant difference among age groups(x2=2.569,P=0.766).The positivity rates for serum antibodies in Shuixigou Town,Lucaogou Town,and Tuoli Township were 17.98％(48/267),14.48％(21/145),and 10.70％(41/383),respectively,with a significantly higher rate in Tuoli Township than Lucaogou Town(x2=7.041,P=0.008).Of 110 individuals who were initially positive for IgG and IgM antibodies with the ELISA,82(10.31％)were con-firmed positive by WB analysis.In total,20(2.52％)patients were diagnosed with Lyme disease based on clinical manifesta-tions.Lyme disease is epidemic among the population in Urumqi,as the infection rate is higher than the national average.Hence,continued surveillance is recommended for prevention of Lyme disease.
