Objective To explore the expression, correlation with clinicopathologic parameters, and clinical significance of MIS18 binding protein 1 (MIS18BP1) in bladder cancer. Methods TCGA and GEO databases were used to analyze the mRNA expression of MIS18BP1 in tumors and controls, and the results were verified via qRT-PCR. UALCAN online database was utilized in the analysis of the expression of MIS18BP1 and its correlation with clinicopathological parameters and the degree of immune cell infiltration. Immunohistochemistry was employed to analyze the expression of MIS18BP1 in bladder cancer and its relationship with clinicopathological features. The ROC curve was applied to evaluate the diagnostic value of MIS18BP1 mRNA in bladder cancer. Results Bioinformatics analysis and qRT-PCR results revealed the increased expression of MIS18BP1 mRNA in bladder cancer compared with that in the control group (P<0.05). Immunohistochemistry unveiled the significantly high positive rate of MIS18BP1 protein in bladder cancer (P<0.05) and its correlation with the clinical stage of tumors, depth of invasion, and lymph node metastasis (P<0.05). The immune infiltration analysis showed the association of MIS18BP1 with immune cell infiltration in bladder cancer. Conclusion The increased expression level of MIS18BP1 gene and protein in bladder cancer may regulate the development of bladder cancer by influencing immune cell infiltration.

Objective:To study and screen the differential expression of inflammatory proteins in diabetes skin ulcers and common skin ulcers, so as to provide experimental basis for further research on anti-inflammatory and healing drug targets of diabetes skin ulcers.Methods:The tissues of 11 patients with diabetes skin ulcer, 12 patients with common skin ulcer and 11 patients with normal skin were collected from the First Hospital of Hunan University of Chinese Medicine. The levels of inflammatory protein Toll like receptor 4 (TLR4), nuclear factor κB (NF-κB), pro-inflammatory factor interferon -γ (IFN -γ), tumor necrosis factor - α (TNF -α), interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-1β (IL-1β), macrophage chemotactic protein-1 (MCP-1), anti-inflammatory factors epidermal growth factor (EGF), interleukin-4 (IL-4), and interleukin-10 (IL-10) were detected in three groups of tissues using enzyme-linked immunosorbent assay (ELISA).Results:Compared with normal tissues, the concentrations of TLR4, NF-κB, IFN -γ, TNF -α, IL-1β, IL-6, IL-8, MCP-1 and EGF in common ulcer skin tissues and diabetes ulcer tissues were higher, and the concentrations of IL-10 were lower, with statistically significant differences (all P<0.05); Compared with the normal tissue, the concentration of IL-4 in diabetes ulcer tissue was lower, the difference was statistically significant ( P<0.05); Compared with ordinary ulcer skin tissue, the concentrations of TLR4, NF-κB and MCP-1 in diabetes ulcer tissue were higher, and the concentrations of IL-4 were lower, with statistically significant differences (all P<0.05). Conclusions:The skin ulcer in diabetes patients will have inflammatory reaction, and high glucose promotes the inflammatory reaction of skin ulcer, which may be related to the abnormal expression of TLR4, NF-κB, MCP-1 and IL-4. TLR4/NF-κB signal pathway and inflammatory factors MCP-1 and IL-4 may be the target of the inflammation regulation of diabetes skin ulcer.

[摘 要] 目的：研究芳香烃受体（AHR）在乳腺癌中的表达及其对乳腺癌细胞增殖、凋亡和药物敏感性的调控机制。方法：通过GEPIA数据库数据分析乳腺癌组织及癌旁组织中AHR的表达水平，探讨其与患者生存期的关联。利用基因敲低和过表达技术构建AHR表达变化的乳腺癌细胞，采用CCK-8实验、细胞计数和流式细胞分析等方法评估AHR对细胞增殖、凋亡和药物敏感性的影响，通过免疫印迹法验证相关分子机制。此外，利用AHR激动剂6-甲酰基吲哚并[3,2-B]咔唑（FICZ）研究外源性激活AHR对乳腺癌细胞多柔比星（DOX）敏感性的影响。结果：GEPIA数据库数据分析结果显示，乳腺癌组织中AHR呈明显低表达（P < 0.05）；对155例乳腺癌患者的生存期进行统计分析也显示AHR低表达与不良预后呈正相关（P < 0.05）。敲低AHR促进细胞增殖（P < 0.05），过表达则能抑制其增殖（P < 0.05）并促进其凋亡（P < 0.05）。外源激活AHR能增强乳腺癌细胞对DOX的敏感性（P < 0.05）。AHR可与MYC基因启动子结合，抑制MYC表达（P < 0.05），从而影响乳腺癌的进展。结论：AHR在乳腺癌中通过调控MYC表达影响细胞增殖和凋亡，外源激活AHR可能成为提高乳腺癌细胞对DOX敏感性的治疗策略。

Objective To investigate whether fenoldopam(FNDP)(an agonist of type 1 dopamine receptor)has a protective effect on thoracic aortic aneurysm(TAA)in mice.Methods Three-week-old male C57BL/6J mice were treated with β-aminopropionitrile(BAPN)to induce TAA.The mice were divided into three groups:the con-trol group,the BAPN group,and the BAPN+FNDP group(FNDP injected intraperitoneally).The incidence and survival rate of TAA were recorded.Gross anatomy of the whole aortae was observed.Elastin staining was per-formed to assess morphological change,while immunohistochemistry was employed to evaluate the expressions of matrix metalloproteinase 2(MMP2),matrix metalloproteinase 9(MMP9)and cluster of differentiation 68(CD68)respectively.Gelatin zymography was conducted to assess MMP2 and MMP9 activity.Reverse transcription-poly-merase chain reaction(RT-PCR)was performed to measure the mRNA expression levels of dopamine receptor D1(D1DR),dopamine receptor d2(D2DR),dopamine receptor d3(D3DR),dopamine receptor d5(D5DR),in-terleukin-1β(IL-1β),interleukin-6(IL-6),tumour necrosis factor-α(TNF-α),monocyte chemoattractant pro-tein-1(MCP-1),alpha-smooth muscle actin(α-SMA)and smooth muscle protein 22-alpha(SM22α).Results Compared to the control group,the BAPN group exhibited significant formation of TAA.Elastic fiber disruption was also observed in the thoracic aortic wall,along with a significant decrease in the mRNA levels of D1DR and D5DR.The BAPN+FNDP group showed a significant reduction in the incidence of TAA formation and the rate of aneu-rysm rupture compared to the BAPN group.The disruption and rupture of elastic fibers in the thoracic aortic wall were significantly improved in the BAPN+FNDP group.The levels of MMP2 and MMP9 in the thoracic aortic wall significantly decreased,and the enzymatic activity of MMP2 in the serum was significantly reduced.Moreover,macrophage infiltration in the thoracic aortic wall was significantly reduced and the mRNA levels of IL-1β,IL-6,TNF-α and MCP-1 also significantly decreased after FNDP treatment.There was no statistically significant differ-ence in the mRNA levels of α-SMA and SM22α.Conclusion FNDP shows an inhibitory effect on TAA progres-sion in mice,suggesting a potential of FNDP as a therapeutic agent for TAA.

Background::Transplant renal artery stenosis (TRAS) is a vascular complication after kidney transplantation associated with poor outcomes. This study aimed to analyze the efficacy and safety of low-dose aspirin for preventing TRAS.Methods::After kidney transplantation, patients were enrolled from January 2018 to December 2020 in Henan Provincial People’s Hospital. A total of 351 enrolled recipients were randomized to an aspirin group with low-dose intake of aspirin in addition to standard treatment ( n = 178), or a control group with only standard treatment ( n = 173). The patients was initially diagnosed as TRAS (id-TRAS) by Doppler ultrasound, and confirmed cases were diagnosed by DSA (c-TRAS). Results::In the aspirin and control groups, 15.7% (28/178) and 22.0% (38/173) of the recipients developed id-TRAS, respectively, with no statistical difference. However, for c-TRAS, the difference of incidence and cumulative incidence was statistically significant. The incidence of c-TRAS was lower in the aspirin group compared with the control group (2.8% [5/178] vs. 11.6% [20/173], P = 0.001). Kaplan–Meier estimates and Cox regression model identified the cumulative incidence and hazard ratio (HR) of TRAS over time in two groups, showing that recipients treated with aspirin had a significantly lower risk of c-TRAS than those who were not treated (log-rank P = 0.001, HR = 0.23, 95% confidence interval [CI]: 0.09–0.62). The levels of platelet aggregation rate ( P < 0.001), cholesterol ( P = 0.028), and low-density lipoprotein cholesterol ( P = 0.003) in the aspirin group were decreased compared with the control group in the third-month post-transplantation. For the incidence of adverse events, there was no statistical difference. Conclusion::Clinical application of low-dose aspirin after renal transplant could prevent the development of TRAS with no significant increase in adverse effects.Trial Registration::Clinicaltrials.gov, NCT04260828.

Combined with Monte Carlo program, the deposited energy of radionuclide particles in rabbit tissues/organs was obtained, and the internal and external exposure dose coefficient for rabbits was calculated following the empirical formula.Results:Simplified anatomy model-based dose coefficients were 129I 4.81 × 10 -6, 137Cs 4.34 × 10 -5, and 134Cs 3.81 × 10 -5(μGy·h -1)/(Bq·kg -1) for internal exposure and 129I 3.16 × 10 -7, 137Cs 2.39 × 10 -4 and 134Cs 6.22 × 10 -4(μGy·h -1)/(Bq· kg -1) for external exposure. respectively. ERICA-based dose coefficients were 129I 4.44 × 10 -5, 137Cs 1.94 × 10 -4 and 134Cs 2.34 × 10 -4(μGy·h -1)/(Bq·kg -1) for internal exposure and 129I 2.19 × 10 -6, 137Cs 2.52 × 10 -4 and 134Cs 6.95 × 10 -4(μGy·h -1)/(Bq·kg -1) for external exposure, respectively. Conclusions:The simplified anatomical model established is based on the measured data and focuses on the radiation doses to biological tissues/organs, and the calculated result based on the present model are closer to the actual situation, and can provide reference values for the reference biological evaluation of non-human species.

Objective:To explore the protective effects of breastfeeding on behavioral problems at 4 years in children born to mothers with gestational diabetes mellitus (GDM).Methods:Based on the Ma' anshan Birth Cohort (MABC) study, 305 GDM women and their children were recruited in this study from Ma' anshan Maternal and Child Health Care Hospital from May 2013 to September 2014. Total breastfeeding duration was followed up at 42 d, 3, 6, 12, and 18 months postpartum as well as the breastfeeding intensity within 6 months. All the subjects were divided into breastfeeding group ( n=256, including exclusive breastfeeding and mixed feeding) or bottle feeding group ( n=49). Internalizing and externalizing behavioral problems at age 4 were assessed using Achenbach Child Behavior Checklist (CBCL/1.5~5) and their association with breastfeeding were analyzed using robust Poisson regression. Controlling false discovery rate was applied for multiple test correction. Results:Compared with bottle feeding, breastfeeding was a protective factor for depression in children ( RR=0.23, 95% CI: 0.05-0.98, q=0.048) when the duration was 4-5 months; for somatic complaints ( RR=0.36, 95% CI: 0.14-0.95, q=0.047) and anxiety ( RR=0.19, 95% CI: 0.06-0.62, q=0.010) with a breastfeeding duration of 6-11 months; and for depression ( RR=0.46, 95% CI: 0.25-0.83, q=0.039) and anxiety ( RR=0.12, 95% CI: 0.03-0.49, q=0.006) with a breastfeeding duration of 12 months and above. Compared with bottle feeding within 6 months, mixed feeding had a protective effect on somatic complaints ( RR=0.29, 95% CI: 0.13-0.64, q=0.026) and anxiety ( RR=0.18, 95% CI:0.07-0.52, q=0.002). Conclusions:The findings suggested that breastfeeding had a protective effect on behavioral problems at age 4 in children exposed to GDM. Women with GDM should be encouraged to breastfeed.

Objective To evaluate the expression of FUNDC1 and its clinical significance in non-small cell lung cancer. Methods We used TCGA database to analyze the difference of mitochondrial receptors (DRP1, BNIP3, FUNDC1, NIX, RHEB, LC3, OPA1 and MFN1) expression between normal and NSCLC tissues, as well as its effect on the prognosis of NSCLC patients. Immunohistochemistry was used to detect FUNDC1 expression. The correlations between FUNDC1 expression and clinicopathological characteristics, prognosis were evaluated by SPSS 22.0 statistical software. Results FUNDC1 expression was increased in NSCLC tissues, compared with normal tissues. FUNDC1 expression was related to the degree of differentiation and lymph node metastasis, but not to gender, age, pathological type, distant metastasis or TNM classification. The Cox regression analysis showed that FUNDC1 protein expression, lymph node metastasis, differentiation degree were independent prognostic factors of NSCLC. Increased FUNDC1 expression was related to decreased OS and PFS (P < 0.01). Conclusion The up-regulation of FUNDC1 expression can affect the prognosis of patients with NSCLC. It may be a new potential target for treating with NSCLC.
