ObjectiveTo explore the academic characteristics of contemporary renowned Chinese medicine masters in treating diabetic kidney disease （DKD） from the perspectives of principles， methods， formulas， and medications. MethodsIn strict accordance with the Systematic Review of Text and Opinion （SrTO） process developed by the Joanna Briggs Institute （JBI）， an Australian evidence-based healthcare center， the databases including China National Knowledge Infrastructure （CNKI）， VIP Database， Wanfang Data， and China Biomedical Literature Service System （SinoMed） were searched. Based on predefined inclusion and exclusion criteria， text information extraction， quality evaluation， and text information synthesis were conducted sequentially. The data were analyzed and presented in the form of text and figures. ResultsA total of 215 articles related to 43 contemporary renowned experts in the fields of Chinese medicine nephrology and endocrinology were included. The study found that the academic thoughts of these masters in the treatment of DKD are extensive， involving multiple levels such as disease understanding， therapeutic strategies， formula application， and medication use. In terms of disease understanding， the primary pathogenesis is characterized by deficiency in the root and excess in the manifestation. It is emphasized that internal factors， such as congenital endowment deficiency， interact with external factors such as improper diet， emotional disturbances， invasion of exogenous pathogens， and delayed or inappropriate treatment， to jointly induce the disease. This further gives rise to various pathogenetic theories， including obstruction of renal collaterals by blood stasis， toxin-induced damage to renal collaterals， latent wind disturbing the kidney， and internal heat leading to mass formation. In terms of therapeutic strategies and medication use， the principal treatment method is to replenish Qi and nourish Yin. Stage-based and syndrome-differentiated treatments are advocated. Flexible use of insect-derived drugs and wind-dispelling drugs is emphasized， along with proficiency in applying classical formulas and drug pairs. Integrated internal and external treatments， as well as the combined application of multiple therapeutic approaches， are commonly employed for comprehensive management. Meanwhile， the concept of "preventive treatment of disease" is upheld， and individualized long-term management of patients is advocated. ConclusionThrough the SrTO process， the academic thoughts of contemporary renowned Chinese medicine masters in the treatment of DKD have been systematically and standardly synthesized， providing a scientific and standardized basis for future theoretical exploration.

Asthma and cough variant asthma （CVA） are both chronic heterogeneous diseases characterized by airway microenvironment homeostasis disruption as their core pathological basis. In recent years， micro ribonucleic acid （miRNA）， as core post-transcriptional regulators， have been shown to finely modulate multiple critical signaling pathways， including Janus kinase/signal transducer and activator of transcription （JAK/STAT）， nuclear factor-κB （NF-κB）， transforming growth factor-β/Smad （TGF-β/Smad）， and phosphoinositide 3-kinase/protein kinase B （PI3K/Akt）， as well as various pathological processes such as airway epithelial barrier restoration， type 1 helper T cell（Th1）/Th2 immune balance， M1/M2 macrophage polarization， airway smooth muscle cell function， and airway hyperresponsiveness. miRNAs play a pivotal role in maintaining and disrupting airway microenvironment homeostasis. Based on recent Chinese and international literature， a logical framework centered on "airway microenvironment homeostasis disruption， miRNA regulation， and microenvironment restoration" was constructed. From the perspective of the airway microenvironment， the therapeutic roles of miRNA in asthma and CVA were systematically summarized， and the cascade regulatory mechanisms of miRNA throughout the entire disease course were elucidated. The hub miRNA was identified， and research progress on traditional Chinese medicine intervention strategies was explored. Furthermore， current clinical studies on RNA therapeutics and traditional Chinese medicine in achieving multi-target and multi-pathway integrated treatment by modulating miRNA were analyzed. The value of miRNA as biomarkers for diagnosis， phenotyping， and prognosis assessment， as well as the potential and application prospects of miRNA mimics and antagonists in precision therapy， were summarized， with the ultimate goal of advancing precision therapy for asthma and CVA.

OBJECTIVE To establish the fingerprint of Gerbera delavayi and the methods for the content determination of 11 components in G. delavayi. METHODS High-performance liquid chromatography（HPLC）was adopted to establish the fingerprints of 13 batches of G. delavayi（No. S1-S13）， and the similarities were evaluated according to Similarity Evaluation System of Chromatographic Fingerprint of TCM （2012 edition）， while the common peaks were identified. Hierarchical clustering analysis （HCA）， principal component analysis （PCA） and orthogonal partial least square-discriminant analysis （OPLS-DA） were carried out by using SPSS 25.0 software and SIMCA 14.1 software. The contents of neochlorogenic acid， chlorogenic acid， cryptochlorogenic acid， 3，8-dihydroxy-4-methoxy-2-oxo-2H-1-benzopyran-5-carboxylic acid， caffeic acid， 3-hydroxy-4-methoxy-2- oxo-2H-1-benzopyran- 5-carboxylic acid， luteolin-7-O-β-D-glucoside， isochlorogenic acid A， apigenin-7-O-β-D-glucoside， isochlorogenic acid C and xanthotoxin were determined by HPLC. RESULTS The similarities in HPLC fingerprint of 13 batches of G. delavayi were 0.801-0.994； a total of 38 common peaks were identified and 13 common peaks were identified. The results of HCA showed that S1-S5 and S7 were clustered into one group， S6 into one category， S8 into one category， S9 and S11 into one category， S10， S12 and S13 into one category， and the results of PCA were consistent with them. The results of OPLS-DA showed that variable importance values for the projection of peak 7 （chlorogenic acid）， peak 21 （isochlorogenic acid A）， peak 26 （xanthotoxin）， peak 19 （isochlorogenic acid B）， peak 33， peak 13， peak 23 （isochlorogenic acid C）， peak 2 （new chlorogenic acid）， peak 17 （luteolin-7-O-β-D- glucoside） were greater than 1. The above 11 components had good linearity in their respective detection concentration ranges （r was greater than 0.999）. RSDs of precision， repeatability， and stability tests were not more than 2% （n＝6）. The average recovery rates were 92.54%-105.55%， and the RSDs were 0.83%-1.93% （n＝6）. The average contents of 11 components were 0.744， 5.014， 0.646， 0.431， 0.069， 0.582， 0.979， 2.754， 0.157， 1.284 and 2.943 mg/g， respectively. CONCLUSIONS The constructed HPLC fingerprint and content determination methods are simple， accurate and stable， which can provide reference for quality control of G. delavayi. Xanthotoxin， chlorogenic acid， isochlorogenic acid A， luteolin-7-O- β -D-glucoside， isochlorogenic acid C and new chlorogenic acid can be used as markers for G. delavayi.

Objective To conduct a quantitative risk assessment of Listeria monocytogenes(LM)in prepackaged,non-vacuum sealed,short shelf-life,ready-to-eat meat products in Chengdu using the@Risk software.Methods Based on monitoring data of LM contamination in pre-packaged,non-vacuum sealed,refrigerated ready-to-eat meat products in Chengdu obtained from a previous study,a risk assessment model was established.The risk of LM infection caused by consuming cooked meat products in different groups of people was quantitatively assessed.In addition,the growth of LM in cooked meat products,from retail to consumption,was also taken into consideration in the assessment.Results In Chengdu,the numbers of potential cases of listeriosis caused by consumption of prepackaged,non-vacuum sealed,refrigerated ready-to-eat meat products were 0.01(95％confidence interval[CI]:0-1.71 × 10-2)per year per million in healthy individuals aged 5-＜65 years old,0.22(95％CI:0-2.67 × 10-1)in healthy individuals aged 65 and above,and 2.88(95％CI:3.85 × 10-8-4.35)in pregnant women.According to the results of the sensitivity analysis,the initial pollution level of LM in the retail stage was the most important factor affecting the prevalence(R=0.25),followed by retail temperature(R=0.08),retail time(R=0.07),and amount of consumption per meal(R=0.07).Conclusions For pre-packaged,non-vacuum sealed,cooked meat products,the most important measure to reduce the prevalence of listeriosis is to control the initial contamination level,which requires food processing plants to regularly clean and strictly disinfect the processing environment and equipment to minimize LM contamination at the source.Retail delicatessens should strictly maintain a storage temperature below 5.0℃ and strictly adhere to product shelf-life recommendations.As for consumers,they should consume these meat products as soon as possible after purchase or store them under refrigerated conditions and shorten the storage time.Pregnant women should thoroughly heat the meat products before eating to reduce the risk of listeriosis.

Objective To comprehensively understand the map of transcripts during mitosis and their regulatory mechanisms of HAP 1 cells by conducting transcriptome sequencing analysis after being released by mitotic synchro-nization arrest.Methods HAP1 cells were subjected to mitotic synchronous arrest with nocodazole and samples were collected after 0,20,80 min release,and RNA sequencing(RNA-seq)were performed.The transcriptome data was cleaned and the differentially expressed genes,expression trend clustering and functional enrichment com-bined with the protein interaction network were analyzed to explore the changes of signaling pathways in HAP 1 cells during mitosis.Results The transcriptome of HAP1 cells after synchronous release from mitosis underwent significant changes in time series,and differential gene cluster analysis revealed four gene clusters were enriched in important biological processes such as p53 signaling and cytoplasmic translation.Conclusions The transcriptome time-dependent dynamic changes during mitosis in HAP1 cells are coordinated regulation of key signaling pathways including cellular stress response,translational control and chromatin remodeling,ensuring a balance between growth and stress response upon mitotic exit.

Extensive epigenetic reprogramming involves in memory CD8+ T-cell differentiation. The elaborate epigenetic rewiring underlying the heterogeneous functional states of CD8+ T cells remains hidden. Here, we profile single-cell chromatin accessibility and map enhancer-promoter interactomes to characterize the differentiation trajectory of memory CD8+ T cells. We reveal that under distinct epigenetic regulations, the early activated CD8+ T cells divergently originated for short-lived effector and memory precursor effector cells. We also uncover a defined epigenetic rewiring leading to the conversion from effector memory to central memory cells during memory formation. Additionally, we illustrate chromatin regulatory mechanisms underlying long-lasting versus transient transcription regulation during memory differentiation. Finally, we confirm the essential roles of Sox4 and Nrf2 in developing memory precursor effector and effector memory cells, respectively, and validate cell state-specific enhancers in regulating Il7r using CRISPR-Cas9. Our data pave the way for understanding the mechanism underlying epigenetic memory formation in CD8+ T-cell differentiation.

Objective To explore the therapeutic effects of temperature-controlled radiofrequency combined with electrical stimulation biofeedback on postpartum dyspareunia in women.Methods In this study,166 patients suffering from dyspareunia due to pelvic floor muscle hypertonicity who visited the Pelvic Floor Rehabilitation Medicine Center of our hospital were selected as subjects.They were randomly divided into three groups:the electrical stimulation biofeedback treatment group(55 cases),the radiofrequency treatment group(55 cases),and the combined electrical stimulation biofeedback and radiofrequency treatment group(56 cases).Patients in the electrical stimulation biofeedback therapy group received only electrical stimulation biofeedback therapy;patients in the radiofrequency group were treated solely with radiofrequency therapy;and patients in the combined treatment group began receiving gynecological radiofrequency treatment from the second week,in addition to the same treatment as the electrical stimulation biofeedback treatment group.To evaluate the effectiveness of the three treatment methods,comparative analyses were conducted on the pelvic floor modified Oxford muscle strength measurement results,pelvic floor surface electromyography values,and sexual function(FSFI)scores of the three groups of patients before and after treatment.Results After treatment,the average resting electromyography(EMG)value of the combined treatment group decreased(P＜0.05),indicating a significant improvement in muscle relaxation function.After treatment,the combined treatment group showed significant improvements in the pelvic floor modified Oxford muscle strength test,the maximum EMG value of fast-twitch(type Ⅱ fibers)muscles,the average EMG value of slow-twitch(type Ⅰ fibers)muscles,and the average EMG value of endurance test,and also demon-strated significant improvements in sexual function(FSFI)scores,which were superior to the electrical stimulation biofeedback treatment group and the radiofrequency treatment group(P＜0.05).Conclusion The combined treatment of temperature control radiofrequency and electrical stimulation with biofeedback has shown significant therapeutic effects in the treatment of postpartum dyspareunia,offering a broad prospect for clinical application.

Objective To investigate the clinical efficacy of intravaginal CO2 fractional laser combined with interferon in treating persistent high-risk HPV infection of the cervix and its impact on vaginal microecology.Methods A total of 211 patients with persistent high-risk HPV infection of the cervix who visited Kunming Maternal and Child Health Care Hospital from June 2022 to July 2024 were selected and randomly divided into a follow-up(blank control)group(n=70),an interferon treatment group(n=70),and a combined treatment group(n=71).The follow-up group received regular follow-ups.The interferon treatment group was treated with recombinant human interferon α-2b,and the combined treatment group received a combination of CO2 matrix laser and interferon treatment.The total effective rate,levels of inflammatory factors,and vaginal microecological recovery were compared among the three groups at 3 and 6 months after treatment.Results Overall efficacy:The overall efficacy rates of the combined treatment group at 3 months and 6 months were 73.24%and 81.69%,respectively,significantly higher than those of the interferon group(47.14%and 60.00%)and the blank control group(11.43%and 18.57%)(all P<0.001).Inflammatory factors:Post-treatment levels of IL-1 and TNF-α in the combined treatment group were significantly lower than those in the other two groups(P<0.001).Vaginal microbiota:The combined treatment group had a significantly higher rate of normal PH(84.51%)and normal lactobacillus levels(92.96%)compared to the other two groups(P<0.001).Conclusion CO2 lattice laser combined with interferon can effectively eliminate HPV,improve inflammation and vaginal microenvironment,and demonstrates superior efficacy to monotherapy,with good safety.

Objective:To analyze the contamination characteristics and pathogenic potential of Listeria monocytogenes (LM) in pre-packaged and refrigerated ready-to-eat cooked meat products in Chengdu City. Methods:From September 2022 to May 2023, pre-packaged and refrigerated ready-to-eat cooked meat products were collected from six districts and counties in Chengdu City. Qualitative and quantitative determination of LM was performed on these samples. Whole genome sequencing was carried out on the isolated strains. Different ST strains were selected for cell adhesion and invasion experiments. The results were expressed as adhesion rate and invasion rate. One-way ANOVA was used for comparison between groups, and the Dunnett t-test was used for pairwise comparison. Results:A total of 145 samples were collected, and LM was detected and isolated in 29 samples. The total detection rate was 20.00%, and the detection rate of braised pork was the highest (68.18%). The contamination level of LM in 9 samples (31.03%) was greater than 100.00 MPN/g. The 29 strains of Listeria monocytogenes belonged to 7 STs, including ST 3 (27.59%), ST 8 (17.24%) and ST 87 (13.79%). The strain of ST 87 carried Listeria pathogenicity islands 4 (LIPI-4), which was a highly virulent strain. The medium and high virulence strains accounted for 79.31%. Some moderately virulent and highly virulent strains of ST 8 and ST 87 were closely related to clinical patient strains. Some LM isolates of the same ST type had little SNP differences (1-6) in the same manufacturer at different stages. In vitro cell experiments showed that the highly virulent strain ST 87 had the strongest adhesion and invasion ability towards Caco-2 cells. Conclusion:The pre-packaged and refrigerated cooked meat products have a high contamination rate. Some samples have high contamination levels and carry medium and high virulence strains, posing potential health risks to human beings. LM residues continue to persist in some manufacturers′ production and processing stages.
