With the rising incidence of diabetes， diabetic kidney disease （DKD） has become a significant global health burden. Although current prevention and treatment strategies can partially delay the progression of DKD， the risk of patients advancing to end-stage renal disease remains high. Since the concept of the "gut-kidney axis" was first introduced at the International Congress on Dialysis in 2011， research on the role of gut microbiota in the pathogenesis of DKD has received increasing attention. This review summarizes the current research on gut microbiota， explores the mechanisms through which it contributes to DKD development， and outlines clinical approaches for DKD prevention and treatment based on the "gut-kidney axis" theory. Evidence indicates that dietary interventions， intake of probiotics or prebiotics， use of metformin and novel antidiabetic drugs， and application of traditional Chinese medicine （TCM） compound formulas can effectively improve gut microbiota composition， influence metabolite production， and restore the intestinal mucosal barrier. These interventions can further regulate intestinal innate immunity and inflammatory responses， thereby modulating the progression of DKD. Despite challenges posed by the traditional oral administration of water-decocted TCM compound formulas and the complexity of their ingredients， increasing evidence suggests that TCM may indirectly affect the occurrence and development of DKD by modulating gut microbiota. This finding provides a new perspective on the potential mechanisms of TCM in DKD treatment and may offer novel strategies for DKD prevention and therapy.

Traditional Chinese medicine （TCM） offers a rich theoretical foundation and clinical experience for the prevention and treatment of cardiovascular-kidney-metabolic syndrome（CKM）， demonstrating unique advantage. Building on previous work in managing diabetes， its complications， and chronic kidney disease， our team has proposed a five-phase evolution theory of "constraint， heat， deficiency， stasis， and toxin" as the core pathogenesis. These phases correspond to the pathological progression of constraint of phlegm-dampness， constraint transforming into heat， heat damaging qi and yin， stasis accumulated in the collateral vessels， and toxin induced by deficiency and stasis. In the prevention and treatment of CKM by TCM， it is emphasized to integrate the concept of "treating disease before it arises" with constitution theory， and incorporate the "2-5-8" prevention and treatment strategy， which combines prevention with treatment， tailors interventions to different phases， and employs comprehensive treatment modalities. Our goal is to leverage TCM's holistic advantages in preventing and treating CKM.

ObjectiveTo investigate the possible mechanism of Shenfuhuang Formula （参附黄配方） in prevention and treatment of epsis-associated encephalopathy from the perspective of brain genomics. MethodsC57BL/6 mice were randomly divided into sham surgery group， sepsis group， and Shenfuhuang group， with 20 mice in each group. The sepsis group and Shenfuhuang group were induced to develop sepsis by cecal ligation and puncture （CLP） procedure. At 4 hours after modelling， Shenfuhuang group were gavaged with 2.5 g/（kg·d） of Shenfuhuang Formula， 0.5 ml each time， at 12 hours intervals， for a total of 4 times after modelling. Sepsis group and sham surgery group were given 0.5 ml of purified water orally. At 48 hours after modeling， the transcriptome sequencing was used to explore the differential gene expression in the effects of Shenfuhuang Formula on the brain regions of septic mice， and real-time PCR and ELISA were later used to further validate the differential gene and proteins expression. ResultsA total of 4605 genes were differentially expressed in Shenfuhuang group compared with sepsis group， of which 2353 genes were up-regulated and 2252 genes were down-regulated. According to the results of previous publications， six key genes were screened， including serine/threonine-protein kinase （Nek1）， myelin-associated glycoprotein （Mag）， endothelial cell-specific tyrosine kinase receptor （Tek）， a disintegrin and metalloproteinase with thrombospondin motifs 20 （Adamts20）， lymphocyte antigen 86 （Ly86）， and E3 ubiquitin-protein ligase （Traip）. Further genetic and protein validation revealed that， compared to the sham surgery group， the mRNA levels and corresponding protein levels of Nek1， Mag， Tek， Adamts20， Ly86， and Traip in the brain tissue of septic mice significantly reduced （P＜0.05）. In comparison to the sepsis group， Shenfuhuang group showed significantly increased mRNA levels and corresponding protein levels of Nek1， Mag， Tek， Adamts20， Ly86， and Traip （P＜0.05）. ConclusionThe potential therapeutic targets of Shenfuhuang Formula for treating sepsis-associated encephalopathy may be related to the Nek1， Mag， Tek， Adamts20， Ly86， and Traip genes and their encoded proteins.

We studied the genetic diversity and established the DNA molecular identify for Prunus mume with both ornamental and edible values, aiming to collect, identify, evaluate, and breed new varities of this plant and promote the upgrading of the P. mume industry chain in northern China. We employed 13 pairs of primers with good polymorphism, clear bands, and good repeatability to analyze the genetic diversity and establish the molecular identify of 68 germplasm accessions of P. mume with both ornamental and edible values from Xingtai, Hebei Province. We then employed the unweighted pair-group method with arithmetic means (UPGMA) to perform the cluster analysis based on genetic distance. After that, we analyzed the genetic structure of the 68 germplasm accessions based on a Bayesian model. The 13 pairs of SSR primers amplified a total of 124 alleles from 68 P. mume germplasm accessions, with the mean number of alleles (Na) of 9.538 5, the minor allele frequency (MAF) of 0.369 3, the mean number of effective alleles (Ne) of 4.483 5, and the mean Shannon genetic diversity index (I) of 1.712 4. The mean Nei's gene diversity index (H) of 0.763 7, the mean observed heterozygosity (Ho) of 0.719 5, the mean expected heterozygosity (He) of 0.769 3, the mean polymorphism information content (PIC) of 0.733 6, and the mean genetic similarity (GS) of 0.772 9 suggested that there were significant genetic differences and rich genetic diversity among the studied P. mume germplasm accessions. The cluster analysis revealed that the 68 accessions were classified into three groups, with the mean genetic distance of 0.622 6. The population structure analysis classified the germplasm accessions into two populations. According to the PIC of primers, we selected primers for combination and constructed the combination with the fewest primers required for germplasm differentiation of P. mume with both ornamental and edible values. This study provides a theoretical basis for the innovation and industrial upgrading of P. mume with both ornamental and edible values in gardening and the improvement of breeding efficiency.

Objective To investigate the predictive value of artificial intelligence-based Alberta Stroke Program Early CT Score(ASPECTS)combined with diffusion-weighted imaging(DWI)cere-bral infarct volume for poor prognosis in wake-up stroke(WUS)patients.Methods A total of 100 patients with acute ischemic stroke after waking up with unknown time window admitted to Kaifeng Cen-tral Hospital from September 2022 to June 2023 were selected as the research objects.All patients un-derwent emergency non-contrast-enhanced cranial CT and magnetic resonance imaging(MRI)scan,followed by reperfusion therapy.The patients were followed up for 3 months after treatment,and were divided into good prognosis[modified Rankin Scale(mRS)≤2]and poor prognosis groups mRS＞2]according to the mRS score.The baseline data,artificial intelligence ASPECTS,and DWI cerebral in-farct volumes were compared between the two groups.Multivariate logistic regression analysis was used to identify prognostic factors,and receiver operating characteristic(ROC)curves were employed to e-valuate the diagnostic efficacy of artificial intelligence ASPECTS combined with DWI cerebral infarct vol-ume.Results After 3 months of follow-up,the poor prognosis rate of patients was 32.00％(32/100).The artificial intelligence ASPECTS at admission in the poor prognosis group was lower than that in the good prognosis group,and the DWI cerebral infarction volume at admission was larger than that in the good prognosis group,with statistically significant differences(P＜0.05).The results of mul-tivariate logistics analysis showed that age(OR=2.190;95％CI,1.412 to 3.398),blood pressure variability(OR=1.726;95％CI,1.192 to 2.500),homocysteine(OR=1.902;95％CI,1.268 to 2.854),D-dimer(OR=2.275;95％CI,1.274 to 4.064),white blood cell count(OR=2.614;95％CI,1.484 to 4.606),neutrophil-to-lymphocyte ratio(OR=2.921;95％CI,1.350 to 6.323),National Institutes of Health Stroke Scale score(OR=3.171;95％CI,1.754 to 5.731),and DWI infarct volume(OR=3.586;95％CI,1.634 to 7.869)were identified as factors affecting poor prognosis(P＜0.05),while high artificial intelligence ASPECTS was identified as a protective factor(OR=0.534;95％CI,0.352 to 0.810;P＜0.05).The sensitivity,specificity and area under the curve of the combined prediction model were 96.88％,85.29％and 0.947,respectively.The sensitivity and AUC of the combined prediction model were higher than that of the single prediction(P＜0.05),and the specificity was similar to that of the single prediction.Conclusion The com-bined application of artificial intelligence ASPECTS and DWI infarct volume significantly enhances predictive efficacy for poor prognosis in WUS patients,providing a more accurate prognostic evalua-tion tool for clinical decision-making,and it has the value of guiding personalized treatment.

Stomach exuberance and spleen deficiency are common pathogenesis of many metabolic diseases. Through analyzing the pathogenesis of stomach exuberance and spleen deficiency， it is believed that its essence is stomach heat and spleen deficiency. Stomach heat includes gastrointestinal heat， spleen and stomach damp-heat， and spleen deficiency is divided into deficiency of spleen yin， deficiency of spleen qi ， and deficiency of spleen yang. It is suggested that the metabolic diseases of stomach-exuberance and spleen-deficiency syndrome can be divided into three categories，i.e. stomach-heat and spleen yin-deficiency， stomach-heat and spleen qi-deficiency， and stomach-heat and spleen yang-deficiency， and the main treatment methods are clearing and draining heat， nourishing yin and moistening intestine， clearing dampness and heat， strengthening spleen and qi， clearing dampness and heat， strengthening spleen and warming yang， respectively， with prescriptions as Maziren Pills （麻子仁丸）， Qinlian Pingwei Powder （芩连平胃散）， and Jiawei Lianli Decoction （加味连理汤） accordingly.

Objective:To determine the predictive value of high-frequency ultrasonography for necrotizing enterocolitis (NEC) requiring surgical treatment in neonates.Methods:From January 2018 to December 2021, neonates diagnosed with NEC (Bell stage Ⅱ and above) in our hospital were retrospectively analyzed. The neonates were assigned into surgical group and non-surgical group according to the treatment. The following ultrasonography results were compared between the two groups: intestinal motility, gastrointestinal (GI) wall perfusion, pneumatosis intestinalis (PI), portal vein gas, peritoneal effusion translucency, depth of ascites fluid and GI wall thickness. Logistic regression was used to determine risk factors of surgical treatment for NEC. ROC curve was drawn to calculate the predictive value of combined and individual factors for NEC requiring surgical treatment.Results:A total of 40 neonates were enrolled, including 18 in the surgical group and 22 in the non-surgical group. No significant differences existed between the two groups in PI and depth of ascites fluid ( P>0.05). The surgical group had higher incidences of decreased intestinal motility, portal vein gas, reduced GI wall perfusion, poor peritoneal effusion translucency and thinner GI wall than the non-surgical group (all P<0.05). Logistic regression analysis showed that poor translucency of peritoneal effusion, thinning of GI wall, reduced GI wall perfusion and decreased intestinal motility were risk factors for surgical treatment of NEC. ROC curve showed that the cut-off value predicting surgical treatment based on GI wall thickness was 1.2 mm, with an area under the curve (AUC) of 0.746, sensitivity of 87.5% and specificity of 65.6%. The AUC of the combined factors predicting surgical treatment was 0.867, with sensitivity of 96.9% and specificity of 75.8%. Conclusions:Decreased intestinal motility and GI wall perfusion, thinning of GI wall and poor peritoneal effusion translucency on high-frequency ultrasonography have high predictive efficacy for the need of surgical treatment in the acute phase of NEC.

Abstract: Heterologous boost COVID-19 vaccination can solved the problem of decreased efficacy caused by single dose of vaccine. Heterologous booster with adenoviral-vectored COVID-19 vaccine (Ad5-nCoV) following primary immunization with inactivated COVID-19 vaccines is a widely-used vaccination strategy in clinic, while different routes of Ad5-nCoV administration exist and pose a question which route could be more optimal. In this study, we comprehensively evaluated and compared the vaccine immunity induced in mice immunized according to three different vaccination regimens: “3×phosphate buffered solution(3× PBS)”, “2×inactivated vaccine + 1×inactivated vaccine (3×INA)”, “2×inactivated vaccine + 1×Ad5-nCoV (intramuscular)[2×INA+Ad5(im)]”and“2×inactivated vaccine + 1×Ad5-nCoV (intranasal)[2×INA+Ad5(in)]”. We found that heterologous booster with Ad5-nCoV, irrespective of the route of administration, induced significantly higher levels of anti-Spike IgG and subclasses (IgG1and IgG2c), Spike-specific T cells, class-switched Spike+ memory B cells (MBCs) than homologous booster with 3rd dose of inactivated COVID-19 vaccine. Of note, compared with the intramuscular given, intranasal given of Ad5-nCoV as a booster dose clearly induced higher levels of serum and bronchoalveolar bavage fluid anti-spike immunoglobulin A, and moreover, induced stronger infiltration of major innate effector cells like neutrophils, natural killer cells and dendritic cells into the lung tissue, which suggested that mucosal vaccine responses are generated upon intranasal booster with Ad5-nCoV. Altogether, our study analyzed the vaccine immunity induced by different COVID-19 vaccines administered using different regimens, which may guide the clinical use of other types of prophylactic vaccines aiming to mount improved vaccine responses.

Nitrate is the main form of inorganic nitrogen that crop absorbs, and nitrate transporter 2 (NRT2) is a high affinity transporter using nitrate as a specific substrate. When the available nitrate is limited, the high affinity transport systems are activated and play an important role in the process of nitrate absorption and transport. Most NRT2 cannot transport nitrates alone and require the assistance of a helper protein belonging to nitrate assimilation related family (NAR2) to complete the absorption or transport of nitrates. Crop nitrogen utilization efficiency is affected by environmental conditions, and there are differences between varieties, so it is of great significance to develop varieties with high nitrogen utilization efficiency. Sorghum bicolor has high stress tolerance and is more efficient in soil nitrogen uptake and utilization. The S. bicolor genome database was scanned to systematically analyze the gene structure, chromosomal localization, physicochemical properties, secondary structure and transmembrane domain, signal peptide and subcellular localization, promoter region cis-acting elements, phylogenetic evolution, single nucleotide polymorphism (SNP) recognition and annotation, and selection pressure of the gene family members. Through bioinformatics analysis, 5 NRT2 gene members (designated as SbNRT2-1a, SbNRT2-1b, SbNRT2-2, SbNRT2-3, and SbNRT2-4) and 2 NAR2 gene members (designated as SbNRT3-1 and SbNRT3-2) were identified, the number of which was less than that of foxtail millet. SbNRT2/3 were distributed on 3 chromosomes, and could be divided into four subfamilies. The genetic structure of the same subfamilies was highly similar. The average value of SbNRT2/3 hydrophilicity was positive, indicating that they were all hydrophobic proteins, whereas α-helix and random coil accounted for more than 70% of the total secondary structure. Subcellular localization occurred on plasma membrane, where SbNRT2 proteins did not contain signal peptides, but SbNRT3 proteins contained signal peptides. Further analysis revealed that the number of transmembrane domains of the SbNRT2s family members was greater than 10, while that of the SbNRT3s were 2. There was a close collinearity between NRT2/3s of S. bicolor and Zea mays. Protein domains analysis showed the presence of MFS_1 and NAR2 protein domains, which supported executing high affinity nitrate transport. Phylogenetic tree analysis showed that SbNRT2/3 were more closely related to those of Z. mays and Setaria italic. Analysis of gene promoter cis-acting elements indicated that the promoter region of SbNRT2/3 had several plant hormones and stress response elements, which might respond to growth and environmental cues. Gene expression heat map showed that SbNRT2-3 and SbNRT3-1 were induced by nitrate in the root and stem, respectively, and SbNRT2-4 and SbNRT2-3 were induced by low nitrogen in the root and stem. Non-synonymous SNP variants were found in SbNRT2-4 and SbNRT2-1a. Selection pressure analysis showed that the SbNRT2/3 were subject to purification and selection during evolution. The expression of SbNRT2/3 gene and the effect of aphid infection were consistent with the expression analysis results of genes in different tissues, and SbNRT2-1b and SbNRT3-1 were significantly expressed in the roots of aphid lines 5-27sug, and the expression levels of SbNRT2-3, SbNRT2-4 and SbNRT3-2 were significantly reduced in sorghum aphid infested leaves. Overall, genome-wide identification, expression and DNA variation analysis of NRT2/3 gene family of Sorghum bicolor provided a basis for elucidating the high efficiency of sorghum in nitrogen utilization.
