Objective To screen the key N6-methyladenosine(m6A)methylation related genes in renal clear cell carcinoma(ccRCC),and to study their expression and relationship with the prognosis,migration and invasion of renal clear cell carcinoma.Methods The RNA sequencing data and clinical data of ccRCC and ad-jacent tissues were downloaded from the Cancer Genome Atlas(TCGA)and GTEx(Genotype-Tissue Expres-sion).The expression profile and prognosis were analyzed with R 4.1.1,and the key genes were screened.Clinical specimens of 10 patients with ccRCC were collected.The mRNA and protein expressions were detec-ted by RT-qPCR and immunohistochemistry,respectively.In human ccRCC cell line RCC23,siRNA was used to knock down key genes,and CCK-8 was used to detect the survival rate of cells.Scratch test and Trans well test were used to detect the migration and invasion of cells,respectively.Results Among the 19 m6A methyl-ation related genes,only insulin-like growth factor 2 mRNA binding protein 3(IGF2BP3)was highly ex-pressed in cancer tissues,and the high expression was significantly positively correlated with poor prognosis.The high expression of IGF2BP3 was verified in clinical specimens by RT-qPCR and immunohistochemistry.After knockdown of IGF2BP3 by siRNA,the survival rate of RCC23 cells decreased significantly,and the mi-gration and invasion ability of cut cells decreased.Conclusion These results suggest that IGF2BP3 may be an effective biomarker and potential drug target for predicting the prognosis of patients with ccRCC.

Objectives:To develop modified prehospital stroke scales and to evaluate their predictive value for in-hospital acute large vessel occlusion (LVO) stroke.Methods:Patients admitted to Dongtai People's Hospital due to non-stroke-related diseases and activated the in-hospital stroke green channel due to suspected stroke symptoms during hospitalization from January 2015 to December 2022 were included retrospectively. According to the final imaging diagnosis, they were divided into LVO group and non-LVO group. The five prehospital stroke scales included Field Assessment Stroke Triage for Emergency Destination (FAST-ED), Rapid Arterial Occlusion Evaluation (RACE), Los Angeles Motor Scale (LAMS), Cincinnati Prehospital Stroke Severity Scale (CPSSS), and Prehospital Acute Stroke Severity Scale (PASS). Multivariate logistic regression analysis was used to determine independent predictive factors of LVO in patients with in-hospital stroke, and incorporating them into the prehospital stroke scale to develop modified scales. The receiver operating characteristic (ROC) curve was used to evaluate the predictive performance of the modified scales. Results:A total of 174 patients with in-hospital stroke were enrolled, including 92 males (52.9%), aged 65.7±11.9 years. Fifty-four patients (31.0%) had LVO, and 59 (33.9%) had a surgical history within 3 days before the onset of stroke, mainly cardiopulmonary surgeries. Multivariate logistic regression analysis showed that atrial fibrillation (odds ratio 2.940, 95% confidence interval 1.387-6.230; P=0.005) and recent history of cardiopulmonary surgery (odds ratio 6.861, 95% confidence interval 2.437-11.315; P<0.001) were the independent predictive factors of LVO in patients with in-hospital stroke. According to the β coefficient and ROC curve, they were assigned a score of 1 and included in the prehospital stroke scale. The area under the curve of the modified scale for predicting LVO (mRACE: 0.917; mFAST-ED: 0.865; mPASS: 0.859; mCPSSS: 0.853; mLAMS: 0.907) was significantly higher than the corresponding original scale (RACE: 0.888; FAST-ED: 0.820; PASS: 0.786; CPSSS: 0.810; LAMS: 0.859) (all P<0.05). Conclusion:The modified scales based on the prehospital stroke scales can significantly improve the predictive value of in-hospital acute LVO stroke compared to the original prehospital stroke scales.

BACKGROUND:
B-cell maturation antigen (BCMA)-directed chimeric antigen receptor T (CAR-T) therapy yield remarkable responses in patients with relapsed/refractory multiple myeloma (R/RMM). Circulating tumor DNA (ctDNA) reportedly exhibits distinct advantages in addressing the challenges posed by tumor heterogeneity in the distribution and genetic variations in R/RMM.
METHODS:
Herein, the ctDNA of 108 peripheral blood plasma samples from patients with R/RMM was thoroughly investigated before administration of anti-BCMA CAR-T therapy to establish its predictive potential. Flow cytometry is used primarily to detect subgroups of T cells or CAR-T cells.
RESULTS:
In this study, several tumor and T cell effector-mediated factors were considered to be related to treatment failure by an integrat analysis, including higher percentages of multiple myeloma (MM) cells in the bone marrow (P = 0.013), lower percentages of CAR-T cells in the peripheral blood at peak (P = 0.037), and higher percentages of CD8+ T cells (P = 0.034). Furthermore, there is a substantial correlation between high ctDNA level (>143 ng/mL) and shorter progression-free survival (PFS) (P = 0.007). Multivariate Cox regression analysis showed that high levels of ctDNA (>143 ng/mL), MM-driven high-risk mutations (including IGLL5 [P = 0.004], IRF4 [P = 0.024], and CREBBP [P = 0.041]), number of multisite mutations, and resistance-related mutation (ERBB4, P = 0.040) were independent risk factors for PFS.
CONCLUSION:
Finally, a ctDNA-based risk model was built based on the above independent risk factors, which serves as an adjunct non-invasive measure of substantial tumor burden and a prognostic genetic feature that can assist in predicting the response to anti-BCMA CAR-T therapy.

Objective:To explore the intervention effects of an Internet-based blood pressure monitoring and management platform in a prehypertensive population.Methods:One hundred and fifty-eight prehypertensive patients who were examined at the Third Xiangya Hospital in Changsha, China, from August to December 2019 were randomly divided into either the experimental or control groups using the random number table method. The experimental group utilized an Internet-based blood pressure monitoring and management platform, whereas the control group utilized regular telephone and SMS health management routines. The intervention duration was 12 months for both groups. Data were analyzed using descriptive analysis, t-tests, chi-square tests, χ 2 tests, and rank-sum tests. Results:Post intervention systolic blood pressure (124.79±9.71 mmHg) (1 mmHg=0.133 kPa) and diastolic blood pressure measurements (77.41±8.21 mmHg) of the participants in the experimental group were significantly lower than those before the intervention (128.29±5.10 mmHg and 79.99±6.01 mmHg, respectively), and significantly lower than those of the control group′s measurements after the intervention (130.00±7.78 mmHg and 80.33±7.90 mmHg, respectively) (all P<0.05). The blood pressure goal attainment rate was significantly higher in the experimental group (23.08%) than that of the control group (8.75%), with statistically significant differences within the experimental group before and after intervention, as well as between the groups post intervention ( P<0.05). Positive lifestyle changes, such as prehypertension knowledge score, active restriction and control of salt and oil intake, reduction of smoking, and exercising weekly, were significantly higher than those in the control group before the intervention (all P<0.05). Conclusion:The use of an Internet-based blood pressure monitoring and management platform can effectively help patients with prehypertension control their blood pressure levels, improve their knowledge about the condition, and improve their lifestyle choices.

MicroRNAs(miRNAs)are trans-acting small regulatory RNAs that work coordinately with transcription factors(TFs)to shape the repertoire of cellular mRNAs available for translation.Despite our growing knowledge of individual plant miRNAs,their global roles in gene regulatory networks remain mostly unassessed.Based on interactions obtained from public databases and curated from the literature,we reconstructed an integrated miRNA network in Arabidopsis that includes 66 core TFs,318 miRNAs,and 1712 downstream genes.We found that miRNAs occupy distinct niches and enrich miRNA-containing feed-forward loops(FFLs),particularly those with miRNAs as intermediate nodes.Further analyses revealed that miRNA-containing FFLs coordi-nate TFs located in different hierarchical layers and that intertwined miRNA-containing FFLs are associated with party and date miRNA hubs.Using the date hub MIR858A as an example,we performed detailed molecular and genetic analyses of three interconnected miRNA-containing FFLs.These analyses revealed individual functions of the selected miRNA-containing FFLs and elucidated how the date hub miRNA fulfills multiple regulatory roles.Collectively,our findings highlight the prevalence and importance of miRNA-containing FFLs,and provide new insights into the design principles and control logics of miRNA regulatory networks governing gene expression programs in plants.

Objective:To understand the characteristics and differences of diarrhea-related symptoms caused by different pathogens, and the clinical features of various pathogens causing diarrhea.Methods:Etiology surveillance program was conducted among 20 provinces of China from 2010 to 2016. The acute diarrhea outpatients were collected from clinics or hospitals. A questionnaire was used to survey demographics and clinical features. VFeces samples were taken for laboratory detection of 22 common diarrhea pathogens, to detect and analyze the clinical symptom pattern characteristics of the patient’s.Results:A total of 38 950 outpatients were enrolled from 20 provinces of China. The positive rates of Rotavirus and Norovirus were the highest among the five diarrhea-causing viruses (Rotavirus: 18.29%, Norovirus: 13.06%). In the isolation and culture of 17 diarrhea-causing bacterial, Escherichia coli showed the highest positive rates (6.25%). The clinical features of bacterial diarrhea and viral diarrhea were mainly reflected in the results of fecal traits and routine examination, but pathogenic Vibrio infection was similar to viral diarrhea. Conclusion:Infectious diarrhea presents different characteristics due to various symptoms which can provide a basis for clinical diagnosis.
