ObjectiveTo observe the effects of electroacupuncture with "tonifying the kidney and dispelling stasis" acupoint prescription on sexual function in diabetic erectile dysfunction (DMED)model rats, and to explore its possible mechanism of action. MethodsSPF male SD rats were randomly divided into 10 each in blank group, model group, Tadalafil group, and electroacupuncture group. DMED rat model was prepared by high glucose and high fat diet combined with intraperitoneal injection of streptozotocin. After successful modelling, rats in the electroacupuncture group were given electroacupuncture intervention of "tonifying the kidney and dispelling stasis" acupoint prescription once every other day; Tadalafil group was given Tadalafil solution 0.5 mg/kg·d by gavage, and the blank group, model group and electroacupuncture group were given 10 ml/kg pure water by gavage once a day. Each group was intervened for 30 days. The body mass and blood glucose level of the rats were detected on the 1st, 8th, 15th, 22nd days and at the end of the intervention, respectively. At the end of the intervention, the penile erection of the rats was observed by using the apomorphine test; the level of plasma endothelial cell microparticles (EMPs)was detected by flow cytometry; the histopathological morphology of the penile cavernous body was observed by HE staining, and the pathological morphology of the endothelial cells of the penile vasculature was observed by electron microscopy. Serum sex hormones including testosterone (T), follicle stimulating hormone (FSH), luteinising hormone (LH) and vascular endothelial function-related factors including vascular endothelial growth factor (VEGF), endothelin-1 (ET-1), lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1), soluble E-selectin (sE-selectin), and soluble intercellular adhesion molecule-1 (sICAM-1) were measured by ELISA method. ResultsCompared with blank group, the model group, Tadalafil group, and electroacupuncture group all had lower body mass and higher blood glucose levels at each time of testing (P<0.01). Compared with the blank group, the number of penile erections reduced in the model group, the level of CD31+ EMPs increased, the levels of serum T, FSH, LH, and VEGF reduced, and the levels of serum ET-1, LOX-1, sE-selectin, and sICAM-1 increased (P<0.01). Compared with the model group, the Tadalafil group and the electroacupuncture group showed an increased number of penile erections decreased level of CD31+ EMPs, increased levels of serum T, FSH, LH, and VEGF, and decreased levels of serum ET-1, LOX-1, sE-selectin, and sICAM-1 (P<0.01). Compared with the Tadalafil group, serum T, FSH, LH, VEGF levels increased and ET-1, LOX-1 levels decreased in the electroacupuncture group (P<0.05 or P<0.01). HE staining and electron microscopic observation revealed that there was severe pathological damage to the cavernous tissue of the penis and vascular endothelial cells of the rat in the model group, which was ameliorated to a certain degree in both Tadalafil group and electroacupuncture group. ConclusionThe electroacupuncture prescription of "tonifying the kidney and dispelling stasis" can improve the erectile dysfunction of DMED rats, which is comparable to the effect of Tadalafi. Its mechanism of action may be related to the regulation of vascular endothelial function.

Objective To explore the correlation of MET status in patients with advanced prostatic acinar adenocarcinoma with the clinical pathological parameters and prognosis. Methods The specimen from 135 patients with advanced prostatic acinar adenocarcinoma was included. The expression of c-MET protein was detected via immunohistochemistry, and MET gene amplification was assessed by fluorescence in situ hybridization. The relationships of c-MET expression and gene amplification with clinicopathological features and prognosis were analyzed. Results The positive expression rate of c-MET was 52.60% (71/135). Compared with the c-MET expression in adjacent tissues, that in tumor tissues showed lower heterogeneous expression. Among the cases, 1.71% (2/117) exhibited MET gene polyploidy, but no gene amplification was detected. Positive c-MET expression was significantly correlated with high Gleason scores and grade groups (P=

Objective:To establish an antibody expression system to reduce the antibody-dependent enhancement (ADE) effect of target antibody.Methods:Site-directed mutagenesis was used to mutate the 234 and 235 sites of the Fc region of the mammalian cell antibody expression vector-L234A and L235A to establish the antibody expression vector pFRT-IgG1κ-FcM. An antibody Wt-WNV with significant ADE effect obtained in previous work was selected and expressed by the pFRT-IgG1κ-FcM system to obtain mutant antibody FcM-WNV. The binding ability of FcM-WNV to target antigen West Nile virus envelope protein-DⅢ (WNV E-DⅢ) was detected by ELISA, and the its binding ability to human high-affinity IgG Fc receptor hFcγRⅠ (hCD64 ) was analyzed by flow cytometry. The neutralizing activity of FcM-WNV in vitro was detected by pseudovirus infection of host cells (BHK21 and K562). Results:The expression levels of FcM-WNV and Wt-WNV were comparable, and FcM-WNV could recognize and bind to WNVE-DIII in a concentration-dependent manner. Compared with Wt-WNV, the binding ability of FcM-WNV to hCD64 was significantly weakened, showing a significant decrease in fluorescence intensity. Consistent with the previous experimental results, Wt-WNV at a concentration of 5 μg/ml significantly enhanced the infection of K562 by WNV pseudovirus, while FcM-WNV at a concentration of 5 μg/ml could effectively block pseudovirus infection in both K562 and BHK21 cells.Conclusions:The established antibody expression system can effectively reduce the ADE effect of the target antibody.

Objective To examine the precise function of influenza A virus target genes(IATGs)in malignancy. Methods Using multi-omics data from the TCGA and TCPA datasets,33 tumor types were evaluated for IATGs.IATG expression in cancer cells was analyzed using transcriptome analysis.Copy number variation(CNV)was assessed using GISTICS 2.0.Spearman's analysis was used to correlate mRNA expression with methylation levels.GSEA was used for the enrichment analysis.Pearson's correlation analysis was used to examine the association between IATG mRNA expression and IC50.The ImmuCellAI algorithm was used to calculate the infiltration scores of 24 immune cell types. Results In 13 solid tumors,IATG mRNA levels were atypically expressed.Except for UCS,UVM,KICH,PCPG,THCA,CHOL,LAMI,and MESO,most cancers contained somatic IATG mutations.The main types of CNVs in IATGs are heterozygous amplifications and deletions.In most tumors,IATG mRNA expression is adversely associated with methylation.RT-PCR demonstrated that EGFR,ANXA5,CACNA1C,CD209,UVRAG were upregulated and CLEC4M was downregulated in KIRC cell lines,consistent with the TCGA and GTEx data. Conclusion Genomic changes and clinical characteristics of IATGs were identified,which may offer fresh perspectives linking the influenza A virus to cancer.

Objective:To establish an in vivo infection model of West Nile virus (WNV) pseudovirus and evaluate the neutralizing activity of antibody WNV-XH1.Methods:A stable cell line that can package the WNV pseudovirus was established in the early stage to prepare the pseudovirus supernatant. The supernatant was concentrated and infected BHK21 cells to detect the titer of the pseudovirus. After intraperitoneal injection of the pseudovirus into C57BL/J mice, bioluminescence imaging was performed to observe the infection status of the pseudovirus in the mice. After simultaneous infection, blood was collected and ELISA was used to detect NS1 levels in mouse serum. The in vivo functional activity of antibody WNV-XH1 was evaluated using the established mouse infection model.Results:Fluorescence was detected in C57BL/J mice infected with WNV pseudovirus, and the NS1 levels in the peripheral blood serum of mice infected with pseudovirus were significantly higher than those of non infected mice (1.453±0.09vs0.305±0.018). After intravenous administration of WNV-XH1 antibody before the attack, the fluorescence signal in the mice decreased and the serum NS1 level decreased (0.384±0.015).Conclusions:A successful in vivo infection model of WNV pseudovirus was established, and it was confirmed that the antibody WNV-XH1 had a protective effect against WNV pseudovirus infection in vivo.

Background::While type 2 diabetes mellitus (T2DM) is considered a putative causal risk factor for coronary artery disease (CAD), the intrinsic link underlying T2DM and CAD is not fully understood. We aimed to highlight the importance of integrated care targeting both diseases by investigating the phenotypic and genetic relationships between T2DM and CAD.Methods::We evaluated phenotypic associations using data from the United Kingdom Biobank ( N = 472,050). We investigated genetic relationships by leveraging genomic data conducted in European ancestry for T2DM, with and without adjustment for body mass index (BMI) (T2DM: Ncase/ Ncontrol = 74,124/824,006; T2DM adjusted for BMI [T2DM adjBMI]: Ncase/ Ncontrol = 50,409/523,897) and for CAD ( Ncase/ Ncontrol = 181,522/984,168). We performed additional analyses using genomic data conducted in multiancestry individuals for T2DM ( Ncase/ Ncontrol = 180,834/1,159,055). Results::Observational analysis suggested a bidirectional relationship between T2DM and CAD (T2DM→CAD: hazard ratio [HR] = 2.12, 95% confidence interval [CI]: 2.01–2.24; CAD→T2DM: HR = 1.72, 95% CI: 1.63–1.81). A positive overall genetic correlation between T2DM and CAD was observed ( rg = 0.39, P = 1.43 × 10 -75), which was largely independent of BMI (T2DM adjBMI–CAD: rg = 0.31, P = 1.20 × 10 –36). This was corroborated by six local signals, among which 9p21.3 showed the strongest genetic correlation. Cross-trait meta-analysis replicated 101 previously reported loci and discovered six novel pleiotropic loci. Mendelian randomization analysis supported a bidirectional causal relationship (T2DM→CAD: odds ratio [OR] = 1.13, 95% CI: 1.11-1.16; CAD→T2DM: OR = 1.12, 95% CI: 1.07-1.18), which was confirmed in multiancestry individuals (T2DM→CAD: OR = 1.13, 95% CI: 1.10-1.16; CAD→T2DM: OR = 1.08, 95% CI: 1.04-1.13). This bidirectional relationship was significantly mediated by systolic blood pressure and intake of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, with mediation proportions of 54.1% (95% CI: 24.9-83.4%) and 90.4% (95% CI: 29.3-151.5%), respectively. Conclusion::Our observational and genetic analyses demonstrated an intrinsic bidirectional relationship between T2DM and CAD and clarified the biological mechanisms underlying this relationship.

ObjectiveTo explore the differences existing in the auditory mismatch negativity (MMN) amplitude and latency between children with attention deficit hyperactivity disorder (ADHD) and normal children, and to probe into the significance of MMN latency and amplitude for assessing the auditory perception and attention level in ADHD children and normal children. MethodsOn December 1, 2022, a systematic search was performed in PubMed, Embase, Cochrane Library, China National knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform and VIP databases to identify all well qualified literature focusing on MMN of ADHD children, then the valid data relevant to MMN amplitude and latency were extracted. The Newcastle-Ottawa Scale (NOS) was used to assess the quality of the included studies, and Stata 20.0 was employed for Meta-analysis. ResultsA total of 9 qualified studies comparing ADHD children (n=170) against healthy controls (n=159) were finally included. Among the included literature, there were 18 matched pairs of MMN amplitude data and 10 matched pairs of MMN latency data at different recording sites. Meta-analysis denoted that ADHD group resulted in potentials of slightly lower MMN amplitude (WMD=-0.334, 95% CI: -1.426~0.758, P=0.549) and notably longer MMN latency (WMD=14.768, 95% CI: 4.660~24.876, P=0.004) compared to control group, and the Bgger's funnel plot did not reveal any publication bias. ConclusionCompared with healthy controls, ADHD children have longer MMN latency, suggesting that the auditory perception and attention level of ADHD children may be reduced.

Objective:To investigate the diagnostic and prognostic value of 68Ga-fibroblast activation protein inhibitor (FAPI) PET for hepatobiliary malignancies. Methods:From July 2020 to February 2023, 33 patients (23 males, 10 females; age (55.4±13.5) years) with suspected or confirmed liver or biliary tract malignancies who underwent 68Ga-FAPI PET in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were retrospectively analyzed. PET images were evaluated by 3 experienced nuclear medicine physicians, and the results of biopsy or postoperative pathology, clinical and imaging follow-up were used as the gold standard. One-way analysis of variance and least significant difference t test were used to compare the differences among groups. Survival analysis was performed using Kaplan-Meier curves and the log-rank test. Results:Of 33 patients, 14 performed PET for initial diagnosis and staging, and 19 for restaging. There were 14 patients with hepatocellular carcinoma (HCC), 13 patients with cholangiocarcinoma (CCA), and 6 patients with gallbladder carcinoma (GBC). The primary tumor of HCC, CCA and GBC all showed significant 68Ga-FAPI uptake, with no statistically significant difference in SUV max among groups ( F=1.58, P=0.250). The sensitivities of 68Ga-FAPI PET for initial diagnosis and restaging of hepatobiliary malignancies were 14/14 and 15/15, respectively. Compared with conventional imaging, 68Ga-FAPI PET changed the diagnosis and staging in 29.2%(7/24) patients. The treatment strategy was changed in 30.3%(10/33) patients with malignant tumors due to 68Ga-FAPI PET findings. Follow-up showed 22 cases survived and 11 cases died, with the overall survival of 355.56(80.00, 516.97) d, and 1- and 2-year survival rates were 68.2% and 57.9%, respectively. Semi-quantitative 68Ga-FAPI PET parameters such as SUV max, target-liver ratio (TLR), and target-blood ratio (TBR) had no significant prognostic value, but the prognosis of the group without distant metastases diagnosed by 68Ga-FAPI PET was significantly better than that of the group with distant metastasis ( P=0.032). Conclusion:68Ga-FAPI PET has high sensitivity for the diagnosis of hepatobiliary malignancies, which can help guide treatment decisions and prognosis evaluation.
