This study aims to explore the medication rules and mechanisms of treating chronic renal failure(CRF) by Jinling medical school based on data mining, network pharmacology, and experimental validation systematically and deeply. Firstly, the study selected the papers published by the inherited clinicians in Jinling medical school in Chinese journals using the subject headings named "traditional Chinese medicine(TCM) + chronic renal failure", "TCM + chronic renal inefficiency", or "TCM + consumptive disease" in China National Knowledge Infrastructure, Wanfang, and VIP Chinese Science and Technology Periodical Database and screened TCM formulas for treating CRF according to inclusion and exclusion criteria. The study analyzed the frequency of use of single TCM and the four properties, five tastes, channel tropism, and efficacy of TCM used with high frequency and performed association rule and clustering analysis, respectively. As a result, a total of 215 TCM formulas and 235 different single TCM were screened, respectively. The TCM used with high frequency included Astragali Radix, Rhei Radix et Rhizoma, Salviae Miltiorrhizae Radix et Rhizoma, Poria, and Atractylodis Macrocephalae Rhizoma(top 5). The single TCM characterized by "cold properties, sweet flavor, and restoring spleen channel" and the TCM with the efficacy of tonifying deficiency had the highest frequency of use, respectively. Then, the TCM with the rules of "blood-activating and stasis-removing" and "diuretic and dampness-penetrating" appeared. In addition, the core combination of TCM [(Hexin Formula, HXF)] included "Astragali Radix, Rhei Radix et Rhizoma, Poria, Salviae Miltiorrhizae Radix, and Angelicae Sinensis Radix". The network pharmacology analysis showed that HXF had 91 active compounds and 250 corresponding protein targets including prostaglandin-endoperoxide synthase 2(PTGS2), PTGS1, sodium voltage-gated channel alpha subunit 5(SCN5A), cholinergic receptor muscarinic 1(CHRM1), and heat shock protein 90 alpha family class A member 1(HSP90AA1)(top 5). Gene Ontology(GO) function analysis revealed that the core targets of HXF predominantly affected biological processes, cellular components, and molecular functions such as positive regulation of transcription by ribonucleic acid polymerase Ⅱ and DNA template transcription, formation of cytosol, nucleus, and plasma membrane, and identical protein binding and enzyme binding. Kyoto Encyclopedia of Genes and Genomes(KEGG) analysis revealed that CRF-related genes were involved in a variety of signaling pathways and cellular metabolic pathways, primarily involving "phosphatidylinositol 3-kinase(PI3K)-protein kinase B(Akt) pathway" and "advanced glycation end products-receptor for advanced glycation end products". Molecular docking results showed that the active components in HXF such as isomucronulatol 7-O-glucoside, betulinic acid, sitosterol, and przewaquinone B might be crucial in the treatment of CRF. Finally, a modified rat model with renal failure induced by adenine was used, and the in vivo experimental confirmation was performed based on the above-mentioned predictions. The results verify that HXF can regulate mitochondrial autophagy in the kidneys and the PI3K-Akt-mammalian target of rapamycin(mTOR) signaling pathway activation at upstream, so as to alleviate renal tubulointerstitial fibrosis and then delay the progression of CRF.

OBJECTIVES: To investigate the expression of apolipoprotein C1 (APOC1) in papillary thyroid carcinoma (PTC) and its effects on proliferation and apoptosis of PTC cells. METHODS: The expression level of APOC1 in PTC and its impact on prognosis were analyzed using GEPIA 2 and Kaplan-Meier databases. Immunohistochemistry (IHC) and Western blotting were used to detect the expression of APOC1 in PTC and adjacent tissues and in 3 PTC cell lines and normal thyroid Nthyori 3-1 cells. In TPC-1 and BCPAP cells, the effect of Lipofectamine 2000-mediated transfection with APOC1 siRNA or an APOC1-overexpressing plasmid on cell growth and colony formation ability were examined by observing the growth curves and using colony-forming assay. The changes in cell cycle and apoptosis of the transfected cells were analyzed with flow cytometry. RT-qPCR and Western blotting were used to detect the changes in expressions of P21, P27, CDK4, cyclin D1, Bcl-2, Bax, caspase-3 and caspase-9 and the key proteins in the JAK2/STAT3 signaling pathway. RESULTS: APOC1 expression was significantly higher in PTC tissues and the 3 PTC cell lines than in the adjacent tissues and Nthyori 3-1 cells, respectively. In TPC-1 and BCPAP cells, APOC1 knockdown obviously reduced cell proliferative activity, increased the percentage of G0/G1 phase cells, lowered the percentages of S and G2 phase cells, promoted cell apoptosis, and downregulated mRNA and protein expression levels of CDK4, cyclin D1 and Bcl-2 and the protein levels of p-JAK2 and p-STAT3. APOC1 overexpression in the cells produced the opposite effects on cell proliferation, apoptosis, cell cycle and the mRNA and protein expressions. The application of AG490, a JAK2 inhibitor, strongly attenuated APOC1 overexpression-induced activation of the JAK2/STAT3 signaling pathway in BCPAP cells. CONCLUSIONS APOC1 overexpression promotes proliferation and inhibits apoptosis of PTC cells possibly by activating the JAK2/STAT3 signaling pathway and accelerating cell cycle progression.

Objective:To compare the clinical efficacy and adverse events of chemoradiotherapy (CRT) combined with immunotherapy versus CRT alone in patients with locally recurrent esophageal squamous cell carcinoma (ESCC) after surgery.Methods:A total of 221 patients with postoperative locally recurrent ESCC who underwent CRT at the Affiliated Huai′an No. 1 People′s Hospital of Nanjing Medical University from January 2020 to December 2022 were retrospectively analyzed. Patients were divided into two groups according to treatment modality: the CRT group ( n=118) and the CRT plus immunotherapy group (combined group, n=103). Among the combined group, 39 patients received camrelizumab, 33 received sintilimab, and 31 received tislelizumab. Short-term efficacy, survival outcomes, and treatment-related adverse events were compared between the two groups. The Cox proportional hazards model was used to analyze prognostic factors for overall survival (OS). Results:No statistically significant differences were observed in baseline clinicopathological characteristics between the two groups. The objective response rate (ORR) in the combined group was 72.8%, significantly higher than 55.9% in the CRT group ( P=0.009). The 1- and 2-year OS rates in the CRT group were 68.6% and 41.5%, respectively, while the 1- and 2-year progression-free survival (PFS) rates were 56.8% and 30.5%, respectively. In the combined group, the 1- and 2-year OS rates were 84.5% and 55.3%, and the 1- and 2-year PFS rates were 67.0% and 42.7%, respectively. The differences in both OS and PFS between the two groups were statistically significant ( P=0.001 and 0.023, respectively). Multivariate analysis showed that Karnofsky performance status score of 70, TNM stage III, and CRT alone were independent risk factors for OS ( P=0.035, 0.031, and 0.002, respectively). The incidence of grade ≥3 adverse events did not differ significantly between the two groups ( P=0.550). A total of 85 grade 1-2 immune-related adverse events (irAEs) and 7 grade ≥3 irAEs occurred in 65 patients in the combined group. Subgroup analysis suggested that tislelizumab combined with CRT showed the most favorable efficacy and safety profile. Conclusion:For patients with locally recurrent ESCC after surgery, concurrent chemoradiotherapy combined with immunotherapy demonstrates promising efficacy with tolerable safety, and may offer a potential therapeutic advantage.

OBJECTIVE: To explore the genotype-phenotype correlation in a Charcot-Marie-Tooth type 2A2A (CMT2A2A) pedigree and to provide genetic counseling for its subsequent pregnancies. METHODS: A Chinese pedigree presenting with "lower limb muscle atrophy and movement disorders" at the Prenatal Diagnosis Center of Xuzhou Central Hospital between January and August 2024 was selected as the study subject. Relevant clinical data were collected from the pedigree members. Peripheral blood samples from affected individuals, and amniotic fluid and/or chorionic villus samples were obtained for DNA extraction. Whole exome sequencing (WES) was carried out. Candidate variants were verified by Sanger sequencing. Pathogenicity assessment and bioinformatic analysis were conducted. This study was approved by the Medical Ethics Committee of Xuzhou Central Hospital (Ethics No. XZXY-LK-20240111-0019). RESULTS: All affected individuals in this pedigree were females, whom included the proband, her mother, and her first daughter. Earlier age of onset was associated with more severe lower limb atrophy. A heterozygous missense variant of the MFN2 gene, namely c.314C>T (p.Thr105Met), was identified in the proband, her mother, daughter, and the third fetus from a re-marriage. The same variant was absent in her elder brother, current husband, and her fourth fetus. Based on the guidelines from American College of Medical Genetics and Genomics (ACMG) and recommendations from Clinical Genome Resources (ClinGen), the variant was classified as pathogenic (PP1_Strong+PM1+PS3+PS4_Moderate+PP3_Moderate+PM2_Supporting). Analyses with PROVEAN and Mutation Taster had categorized the variant as "deleterious" and "disease-causing", respectively. Analysis with Uniprot and Jalview showed that the affected amino acid residue is conserved across multiple species. ChEBI software predicted that the variant may alter the polarity of the 105th amino acid residue. CONCLUSION The c.314C>T (p.Thr105Met) missense variant of the MFN2 gene probably underlie the CMT2A2A in this pedigree. Above finding has enabled prenatal diagnosis and genetic counseling for its subsequent pregnancies.

Objective:To evaluate the cumulative relationship between individual cardiometabolic diseases(CMDs)and the incidence of cataract in the elderly.Methods:This study was a prospective cohort study based on the UK Biobank, including 165 222 participants without cataract at baseline, aged 60.0 to 74.0 years, with an average age of(64.9±2.9)years, including 76 712 males(46.4%)and 88 510 females(53.6%). The exposure in this study was CMDs(including coronary heart disease, stroke, diabetes, and hypertension), and the outcome was the incidence of cataract.The Cox proportional hazards model was used to evaluate the cumulative hazard ratio( HR)and 95% confidence interval( CI)of the number of CMDs and cataract occurrence in the elderly. Results:After a median follow-up of 13.65 years, 35, 933 cataract events were observed.After adjusting for various factors, the HRs of cataract incidence in elderly patients with 1, 2, and 3 or more CMDs compared with those without CMDs were 1.11( HR=1.11, 95% CI: 1.08~1.14, P<0.001), 1.38( HR=1.38, 95% CI: 1.33~1.43, P<0.001), and 1.80( HR=1.80, 95% CI: 1.68-1.93, P<0.001), respectively.There was a significant dose-cumulative effect between the number of CMDs and the risk of cataract( HR=1.17, 95% CI: 1.15~1.19, P<0.001). Conclusions:The coexistence of CMDs in the elderly is an important risk factor for cataract development, and the risk of cataract increases in a dose-cumulative manner with the increase in the number of CMDs, suggesting that emphasizing health management of CMDs in the elderly population may help reduce the incidence of cataract.

Objective:To investigate the factors influencing sound localization in patients with unilateral sudden sensorineural hearing loss, so as to provide the reference for hearing rehabilitation of patients with unilateral sudden hearing loss.Methods:This study was a cross-sectional study that retrospectively analyzed the clinical data and audiological examination results of 228 patients with unilateral sudden sensorineural hearing loss(103 males and 125 females; aged from 18 to 80 years, with an average age of 46.2 years; 107 cases in the left ear and 121 cases in the right ear; 8 cases of low-frequency decline type, 42 cases of high-frequency decline type, 92 cases of flat decline type, and 86 cases of total deafness type)at the Eye and ENT Hospital of Fudan University from June 2023 to April 2024. The minimum audible angle (MAA) was calculated by the angle discrimination test of 1000 Hz and 4000 Hz warble tones, which were recorded as MAA 1 000 and MAA 4 000 according to the frequency of the given sound stimulus. The root mean square error (RMSE) was calculated by the angle recognition test with daily natural sounds as the stimulus sound. Using SPSS 27.0 statistical software, correlation and multiple regression analysis were used to research the clinical factors affecting the ability of sound localization in patients with unilateral sudden sensorineural hearing loss. Results:The mean MAA 1 000, MAA 4 000, RMSE of patients with unilateral sudden deafness were (53.97±29.14)°, (46.34±28.87)° and (30.06±13.64)°, respectively. Univariate analysis of variance revealed that there were significant differences between different classifications of sudden sensorineural hearing loss for sound localization tests (MAA 1 000: F=6.338, P<0.001,MAA 4 000: F=14.334, P<0.001,RMSE: F=49.918, P<0.001), post-hoc analysis observed that all significant contrasts were included the type of total deafness and low-frequency deafness. Correlation analysis showed the age of subjects in this study was weak positively correlated to the MAA 1 000 ( r=0.165, P=0.013), the duration of sudden sensorineural hearing loss was weak negatively related to RMSE ( r=-0.144, P=0.030), there were significant positive relationships between the threshold of PTA, PTA 1kHz, PTA 4kHz for the affected side, as well as the binaural PTA difference and sound localization test (MAA 1 000,MAA 4 000,RMSE) (all P<0.001). The multiple regression analysis showed the age and the binaural PTA difference for the affected side were the significant factors for the MAA 1 000 and MAA 4 000, the binaural PTA difference was the significant factors for the RMSE. The R 2 of multivariable linear regression model for MAA 1 000, MAA 4 000 and RMSE results in unilateral sudden deafness patients were 0.149, 0.207 and 0.553, respectively. Conclusion:Age, the hearing of the affected side, and binaural PTA difference are the significant factors for sound localization ability in patients with unilateral sudden sensorineural hearing loss, hearing compensation of the affected ear for these patients is hopeful to enhance the sound localization ability.
