ObjectiveTo evaluate the effect of Ningying Formula （宁瘿方） combined with low-dose antithyroid drugs （ATDs） on the relapse risk for patients with Graves' hyperthyroidism （GH） during the remission phase， and to analyze the related factors between GH relapse and thyrotropin receptor antibody （TRAb） negativity， so as to provide evidence for the standardized management of GH in remission stage. MethodsA single-center retrospective cohort study was conducted， including 269 GH patients in the remission stage. After propensity score matching （PSM）， 102 matched pairs （204 patients） were established. The control group received low-dose ATDs as maintenance therapy， while the exposure group received the core Ningying Formula in addition to low-dose ATDs. The primary outcome was the GH recurrence rate； the secondary outcome was the thyrotropin receptor antibody （TRAb） negativity rate （TRAb＜1.75 IU/L）. Safety outcomes included treatment-related adverse events. Differences between groups were assessed using Cox regression models and Kaplan-Meier curves， with sensitivity analysis performed using inverse probability of treatment weighting （IPTW）. ResultsThe median follow-up in the matched cohort was 28.07 months. Regarding the GH recurrence outcome， the recurrence rate in the exposure group （18/102， 17.6%） was significantly lower than that in the control group （31/102， 30.4%； χ²=4.539， P=0.033）； regarding the TRAb negativity outcome， the TRAb negativity rate in the exposure group （50/102， 49.0%） was significantly higher than that in the control group （23/102， 22.5%； χ²=15.551， P＜0.001）. Multivariate Cox regression analysis for recurrence showed that Ningying Formula treatment reduced the risk of recurrence ［HR=0.324， 95%CI（0.170， 0.617）， P＜0.001］. Male ［HR=2.209， 95%CI（1.079， 4.520）， P=0.030］， higher initial TRAb level ［per 1 IU/L increase： HR=1.033， 95%CI（1.003， 1.064）， P=0.032］， and larger thyroid volume ［per 1 ml increase： HR=1.045， 95%CI（1.003， 1.088）， P=0.035］ were identified as independent risk factors for recurrence； multivariate Cox regression analysis for TRAb negativity indicated that Ningying Formula treatment promoted TRAb negativity ［HR=1.826， 95%CI（1.091， 3.056）， P=0.022］， while a higher initial TRAb level was associated with a lower probability of negativity ［HR=0.974， 95%CI（0.950， 0.998）， P=0.032］. Survival analysis showed significant differences in relapse rate between groups （Log-Rank P=0.003） and in TRAb outcomes （Log-Rank P=0.034）. The incidence of treatment-related adverse events was similar between groups （P=0.757）. The IPTW sensitivity analysis was consistent with the primary analysis， indicating robust results. ConclusionThe Ningying Formula combined with low-dose ATDs can significantly reduce the risk of recurrence and can improve the TRAb negativity rate in GH patients during the remission stage， without increasing common adverse events， making it an optional strategy for reducing relapse risk during remission. Male gender， higher baseline TRAb level， and larger thyroid volume indicate a higher risk of recurrence， warranting focused follow-up and stratified management.

Objective To systematically identify key risk biomolecules associated with the diagnosis of prostate cancer using multi-omics analysis methods, and to explore potential drug intervention targets. Methods Based on prostate cancer genome-wide association study data, GTEx v8 expression quantitative trait locus data, and The Cancer Genome Atlas database, this study screened for differentially expressed genes associated with prostate cancer pathogenesis through transcriptome imputation, summary data-based Mendelian randomization (SMR) analysis, colocalization analysis, and differential expression analysis.The identified differentially expressed genes were subjected to gene ontology analysis, single-cell RNA sequencing analysis, and correlation analysis with immune cell infiltration levels.Mendelian randomization (MR) was employed to investigate immune pathways and circulating metabolites associated with prostate cancer diagnosis.Potential drug targets for prostate cancer were screened using SMR analysis. Results Four differentially expressed genes associated with prostate cancer were identified, among which BHLHA15 (OR=1.08) was found to be associated with prostate cancer risk for the first time. MR analysis revealed that immune cell surface molecules and the inflammatory cytokine interleukin-17A (IL-17A) (OR=1.25) were risk factors for prostate cancer.MR analysis also indicated that higher levels of sebacate (OR=1.05) and cystine disulfide (OR=1.11) were associated with an increased risk of prostate cancer.Drug target analysis screened 14 potential target genes, among which high expression of OPRL1 was significantly correlated with poorer disease-free survival in prostate cancer patients (HR=2.00, P=0.024). Conclusion This study identified biomolecules associated with prostate cancer pathogenesis through multi-omics analysis, which may help deepen the clinical understanding of the pathogenic mechanisms underlying prostate cancer and reveal potential drug targets.

ObjectiveTo investigate the effects of Guizhi Fulingwan on oxidative stress and renal fibrosis in diabetic mice based on the nuclear factor E₂-associated factor 2/antioxidant response element （Nrf2/ARE） pathway， and to explore its mechanism of action. MethodA diabetic mouse model was established by feeding high-fat diet combined with intraperitoneal injection of streptozotocin. The diabetic mice were divided into a model group， a metformin group （250 mg·kg^-1）， and Guizhi Fulingwan low， medium， and high dose groups （400.4， 800.8， 1 601.6 mg·kg^-1）， with 10 mice in each group. Another 10 mice were included in a normal group. The treatment was conducted continuously for 8 weeks. Body mass and blood glucose were recorded， and the renal index was calculated. Triglyceride （TG）， total cholesterol （TC）， urea nitrogen （BUN）， serum creatinine （SCr）， superoxide dismutase （SOD）， and malondialdehyde （MDA） levels were measured. Pathological changes in renal tissues were observed using Hematoxylin-eosin， periodate-Schiff， and Masson staining. The protein levels of α-smooth muscle actin （α-SMA）， fibronectin （FN）， and transforming growth factor-β₁ （TGF-β₁） were detected by immunohistochemistry. The protein levels of Nrf2， Kelch-like ECH-associated protein 1 （Keap1）， SOD1， NAD（P）H single-nucleotide oxidase 1 （NQO1）， and heme oxygenase-1 （HO-1） were detected by Western blot. ResultCompared with the normal group， the model group showed elevated glucose， renal index， TG， TC， BUN， and SCr levels， thickened glomerular basement membrane， increased collagen fibers in renal tissues， decreased SOD activity， elevated MDA content， increased protein levels of FN， TGF-β₁， α-SMA， and Keap1， and decreased protein levels of Nrf2， SOD1， NQO1， and HO-1 （P<0.01）. Compared with the model group， the Guizhi Fulingwan and metformin groups showed reduced blood glucose， renal index， TG， TC， BUN， and SCr levels， improved renal histopathological injury， significantly increased SOD activity， significantly reduced MDA content， reduced protein levels of FN， TGF-β₁， α-SMA， and Keap1， and increased protein levels of Nrf2， SOD1， NQO1， and HO-1 （P<0.05， P<0.01）. ConclusionGuizhi Fulingwan can improve oxidative stress and inhibit renal fibrosis， and its mechanism may be related to the activation of the Nrf2/ARE signaling pathway.

The outbreak of coronavirus disease 2019 (COVID-19) has spread rapidly around the world. As of May 30, 2020, a total of 84 568 confirmed COVID-19 cases have been recorded in China, with a mortality rate of approximately 5.5%. Taizhou is a prefecture-level city in Zhejiang Province. A total of 146 cases were diagnosed in this epidemic, with a fatality rate of 0%. This condition is due to the establishment of an "Internet +" diagnosis and treatment model based on online medical application (APP), telemedicine, WeChat service, and consultation hotline in Taizhou. Taizhou led in opening the "COVID-19 Prevention and Treatment Special Line" in China, which is conducive to pre-hospital screening, suppressing social panic, and clinical support. Hospitals also carried out related online lectures and popularization of science. We summarize Taizhou's COVID-19 prevention and control experience with telemedicine features, with a view to providing reference for the control of the epidemic at home and abroad.

Objective:To explore the efficacy and safety of pretreating with oral immunosuppressants alone for ABO-incompatible (ABOi) renal transplant recipients with an initial isoagglutinin titer <1: 8.Methods:From September 2014 to October 2019, 16 cases of ABOi renal transplantation pretreated with oral immunosuppressants alone and 32 cases of ABO-compatible (ABOc) renal transplantation were recruited for comparing the inter-group incidence of graft function, acute rejection, infection and recipient and allograft survival.Results:The 16 ABOi renal transplantations were AB-to-A(n=4), AB-to-B(n=3), A-to-B(n=1), B-to-A(n=4), A-to-O(n=2) and B-to-O(n=2). The initial isoagglutinin titer (IgM & IgG) and that on the date of transplantation were both ≤1∶8. The median follow-up period was 495(90-1696) days. One patient in ABOi group underwent allograft nephrectomy due to hyperacute rejection. The graft survival rates were 93.75%(15/16) and 100%(32/32) in ABOi and ABOc groups respectively. No recipient died. No significant inter-group difference existed in postoperative renal function after 6 months (serum creatinine μmol/L: 114.30±28.13 vs. 106.08±23.80, P=0.38; eGFR ml/min/1.73 m 2: 64.93±19.60 vs. 82.34±22.58, P=0.13). In ABOi group, there were 3 episodes of postoperative infection, 2 episodes of acute rejection within 2 weeks (including 1 episode of hyperacute rejection) and 1 episode of acute rejection after 2 weeks; 5 episodes of postoperative infection, no acute rejection within 2 weeks and 5 episodes of acute rejection after 2 weeks in ABOc group. No significant inter-group difference existed in the incidence of infection or rejection ( P>0.05). Conclusions:Using oral immunosuppressant alone is both safe and feasible for ABOi renal transplantation recipients with an initial isoagglutinin titer ≤1∶8. It may greatly simplify the pretreatment scheme for those with a low initial isoagglutinin titer and lower the incidence of complications.
