Objective:To analyze the current management status of real-world studies (RWS) in the medical institutions in China and suggest improvement focus for the management optimization.Methods:Surveys were conducted in 81 medical institutions nationwide. Convenience sampling was used to recruit survey subjects, and data were collected through self-administered questionnaires, followed by statistical analysis using descriptive methods.Results:The survey results indicated that 92.6% (75/81) of the medical institutions surveyed had undertaken RWS projects, with electronic medical records being the primary data source (89.3%, 67/75). Retrospective and prospective observational studies were the main types of study designs. Additionally, 96.3% (78/81) of the research subjects indicated that their medical institution expressed willingness to participate in or undertake RWS projects in the future. In terms of management, all types of RWS projects were managed by clinical trial center (24.0, 18/75), but differences existed in the management practices among medical institutions. Moreover, the challenges in data quality and standardization, study design and staff training, data and privacy protection and information technology support appeared in the management of RWS projects.Conclusions:It suggests to optimize the management processes of RWS projects in medical institutions and improve relevant laws and regulations to promote the development of RWS in China.

Chimeric antigen receptor T (CAR-T) lymphocytes are at the forefront of adoptive immunotherapy research, and this technology has significantly advanced the prospects of tumor immunotherapy. CAR-T therapy has demonstrated remarkable efficacy in haematological tumours of lymphoid origin and provided therapeutic possibility for solid tumours. Currently, CAR-T cell preparation predominantly involves transfection of T cells with viral vectors. However, the production of viral vectors is time-consuming, expensive, and the vectors have low loading capacity, along with insertion instability. Consequently, there is a pressing need to develop more convenient and precise non-viral gene delivery methods. This paper reviews the most promising non-viral gene delivery technologies, including CRISPR/Cas9 gene editing, transposon systems such as Sleeping Beauty (SB) and PiggyBac (PB), and mRNA, and anticipates the future development of non-viral vector-based CAR-T therapies.

Objective To understand the current status of traditional Chinese medicine(TCM)systematic reviews/Meta-analysis over the past 10 years.Methods Cochrane Database of Systematic Reviews,PubMed,Web of Knowledge,CNKI,SinoMed,WanFang Data,VIP databases,as well as the Cochrane Register and PROSPERO registration platform were searched to collect TCM-related systematic reviews/Meta-analysis published between January 2015 and December 2024.Literature was screened,and standardization of institutions,countries,and journals was performed.Data cleaning was conducted,and trends in publication years,high-frequency diseases,journals,institutions,and highly cited papers were analyzed.Results A total of 11,174 papers were included,involving approximately 56,656 authors from 1,422 institutions across 44 countries,covering 1,300 journals and 1,070 diseases.The top five institutions in terms of publications were Beijing University of Chinese Medicine(954 papers),Guangzhou University of Chinese Medicine(928 papers),China Academy of Chinese Medical Sciences(537 papers),Tianjin University of Chinese Medicine(460 papers),and Chengdu University of Chinese Medicine(393 papers).Foreign institutions with the highest publication volumes were concentrated in South Korea,Iran,and Australia.The most frequently published Chinese journal was Zhongyi Clinical Research with 332 papers,while the most published English journal was Evidence-Based Complementary and Alternative Medicine with 311 papers.There were 282 single-author papers involving 271 authors,and the most cited paper was referenced 323 times,The three most frequently studied diseases were diabetes(267 papers,2.39％),angina pectoris(214 papers,1.92％),and osteoarthritis(210 papers,1.88％).Non-pharmacological interventions such as acupuncture(1,265 papers,11.32％),auricular therapy(101 papers,0.90％),and Tai Chi(98 papers,0.88％)were most frequently reported.In pharmacological interventions,studies on Tripterygium wilfordii tablets(76 papers,0.68％)and Danhong injection(54 papers,0.48％)were more common.Conclusion The systematic reviews/Meta-analysis method is widely used in the field of TCM,and the field continues to grow.Active academic teams,institutions,and journals have emerged.Over the past decade,there has been a considerable body of evidence in Chinese systematic reviews on TCM for chronic diseases such as diabetes,angina pectoris,and osteoarthritis.In English-language studies,non-pharmacological therapies like acupuncture have been more widely reported,and some high-impact studies have emerged.However,challenges remain,such as issues with research transparency and methodological standardization.Future efforts should focus on establishing transparent systems and quality control mechanisms to further enhance the reliability,accuracy,and dissemination of TCM evidence-based research.

Follicular variant of papillary thyroid carcinoma(FVPTC)is commonly found in young and middle-aged women,and cases in children and adolescents are relatively rare.The main driving genes of FVPTC are the RAS oncogene family or B-Raf proto-oncogene serine/threonine protein kinase(BRAF),and DICER1 gene mutation is rarely reported in this subtype.This article reports a case of recurrent FVPTC with positive DICER1 mutation in an adolescent,aiming to provide reference for the clinical diagnosis and treatment of FVPTC.The patient,a 19-year-old female,underwent total thyroidectomy and central lymph node dissection due to thyroid nodules 5 years ago,and was pathologically diagnosed with follicular tumor of uncertain malignant potential(FT-UMP);after surgery,the patients did not regularly undergo thyroid-stimulating hormone(TSH)suppression therapy and follow-up as instructed.Two months ago,the patient visited the hospital due to enlarged cervical lymph nodes,imaging suggested tumor recurrence with metastases to both lungs and vertebrae,and multigene testing indicated a DICER1 gene mutation.After comprehensive multidisciplinary consultation,bilateral cervical lymph node dissection was performed,and postoperative pathology confirmed the diagnosis of metastatic FVPTC.Te clinicans should focus on rare gene mutations such as DICER1 in the FVPTC patients,and for adolescent patients,follow-up and formulation of individualized treatment plans should be emphasized to achieve early tumor identification and precise intervention,and improve the long-term prognosis of patients.

Protein liquid-liquid phase separation (LLPS), a pivotal phenomenon intricately linked to cellular processes, is regulated by various other proteins. However, there is still a lack of high-throughput methods for screening protein regulators of LLPS in target proteins. Here, we developed a CRISPR/Cas9-based screening method to identify protein phase separation regulators by integrating bimolecular fluorescence complementation (BiFC) and fluorescence-activated cell sorting (FACS). Using this newly developed method, we screened the RNA-binding proteins that regulate PABPN1 phase separation and identified the tumor suppressor QKI as a promoter of PABPN1 phase separation. Furthermore, QKI exhibits decreased expression levels and diminished nuclear localization in colorectal cancer cells, resulting in reduced PABPN1 phase separation, which, in turn, promotes alternative polyadenylation (APA), cell proliferation, and migration in colorectal cancer.

Objective To investigate potential causative associations between immunophenotype traits and cervical cancer by using two-sample Mendelian randomization(MR)analysis.Methods The genetic instrumental variables(IVs)of 731 immunophenotypes of peripheral blood were obtained from the GWAS Catalog database.The GWAS summary data of cervical cancer were obtained from FinnGen database.The inverse-variance weighted(IVW),weighted mode,weighted median,and MR Egger methods were used for evaluations.The sensitivity analysis and reverse Mendelian randomization analysis were conducted to eliminate bias and reverse causality.The MR Steiger directionality test was further used to ascertain the reverse causal relationship between immune cells and cervical cancer.Results A total of 71 immune cell subtypes associated with cervical cancer were identified,of which 31 had a strong association.The majority of the B cell panel was protective factors for cervical cancer.B-cell activating factor receptor(BAFF-R)was the most frequently expressed molecule in this analysis.It is expressed on several B cell subtypes.The CD20 on IgD+CD38+B cell(OR=1.887,95%CI:1.078-3.306,P=0.026)is the risk factor for cervical cancer.In cDC panels,the CD123 expression on plasmacytoid dendritic cell(OR=2.48,95%CI:1.229-5.003,P=0.011),CD123 expression on CD62L+plasmacytoid dendritic cell(OR=2.5,95%CI:1.231-5.077,P=0.011),CD80 expression on plasmacytoid dendritic cell(OR=2.62,95%CI:1.244-5.515,P=0.011),and CD80 expression on CD62L+plasmacytoid dendritic cell(OR=2.641,95%CI:1.246-5.596,P=0.011)were positively associated with the incidence of cervical cancer.All gynecological cancers in this study have no statistically significant effect on immune cells,according to reverse MR analysis.Conclusion This study emphasized the genetically predicted causality between immune cells and cervical cancer.In clinical practice,it is important to pay attention to the screening of peripheral blood immune cells for patients with cervical cancer.

Objective To investigate whether curcumin alleviates septic lung injury by inhibiting ferroptosis through modulating the TXNIP/TRX-1/GPX4 pathway.Methods Male C57BL/6 mice were randomly divided into Sham group,cecal ligation puncture(CLP)-induced sepsis group,CLP with curcumin treatment(50,100,and 200 mg/kg)groups,and CLP with both curcumin(200 mg/kg)and TRX-1 inhibitor PX-12(25 mg/kg)treatment group.Inflammatory factors,MDA,MPO,and GSH levels in the lung tissue of the mice were detected.Beas-2B cells stimulated with lipopolysaccharide(LPS;1 μg/mL)were treated with 2.5,5,or 10 μmol/L curcumin or with 10 μmol/L curcumin combined with 5 μmol/L PX-12,and the changes in MDA,Fe2+and ROS levels were assessed.Western blotting was performed to detect the protein expressions of TXNIP,TRX-1,GPX4 and X-CT in both the mouse lung tissues and Beas-2B cells.Results The mice with CLP-induced sepsis showed severe lung injury with elevated expressions of IL-6,IL-1β,TNF-α,MDA and MPO and decreased GSH expression.In Beas-2B cells,LPS stimulation significantly increased MDA and Fe2+levels and ROS release,increased TXNIP protein expression,and lowered the protein expression levels of TRX-1,GPX4 and X-CT,and these changes were also observed in the septic mice.Curcumin treatments at different concentrations obviously alleviated lung injury in the septic mice and reduced LPS-induced injury in Beas-2B cells.Curcumin significantly decreased the release of inflammatory factors,MDA and MPO,increased GSH level,lowered Fe2+,MDA and ROS levels,increased TXNIP protein expression,and lowered the protein expressions of TRX-1,GPX4 and X-CT in both septic mouse lung tissues and LPS-stimulated Beas-2B cells.The protective effect of curcumin was effectively blocked by PX-12 treatment.Conclusion Curcumin inhibits ferroptosis and alleviates septic lung injury in mice by elevating TRX-1 and GPX4 and decreasing TXNIP in the lung tissue.
