Objective To analyze the correlation between digital mammography features,lymphocyte to monocyte ratio(LMR)and prognosis in patient with invasive breast cancer,and to explore the prognostic value of digital mammography features and LMR in invasive breast cancer.Methods Ninety-six patients with invasive breast cancer were selected.The data of digital mammography features and serum LMR levels were analyzed.The patients were followed up after discharge.According to different prognosis,all patients were divided into good prognosis group(68 cases)and poor prognosis group(28 cases).Spearman was used to analyze the correlation of digital mammography features,LMR level and prognosis of patients.Receiver operating characteristic(ROC)curve was drawn to analyze the prognostic value of digital mammography features and LMR level.Results The spicule sign and proportion of calcifica-tion in the poor prognosis group was significantly higher than that in the good prognosis group,the maximum diameter of tumor was significantly larger than that in the good prognosis group,and the serum LMR level was significantly lower than that in the good prognosis group(P＜0.05).Spearman correlation analysis showed that spicule sign,proportion of calcification and maximum diame-ter of tumor were positively correlated with poor prognosis of invasive breast cancer(P＜0.05).Serum LMR level was negatively correlated with poor prognosis of invasive breast cancer(P＜0.05).ROC curve analysis showed that the area under the curve(AUC)of spicule sign,calcification and tumor maximum diameter combined with LMR level to evaluate the prognosis of invasive breast cancer was 0.927,the sensitivity was 89.71％,and the specificity was 82.14％,which were significantly higher than those of each index alone.Conclusion Digital mammography and serum LMR levels may be closely related to the prognosis of patients with invasive breast cancer,and spicule sign,calcification,tumor maximum diameter combined with serum LMR may be of significant prognostic value in invasive breast cancer.

To investigate the short-term effectiveness and safety of sublingual allergen immunotherapy with allergen sprays (SLIT-sprays) in Chinese patients with allergic rhinitis (AR) with or without asthma using real-world data. The retrospective cohort study included 100 patients who received SLIT-sprays in the ENT departments in Hainan Shulan (Boao) Hospital and Boao Super Hospital between October 2023 and August 2024. A questionnaire survey was conducted to collect clinical data on the effectiveness and safety of SLIT-sprays, examining the types and incidence of adverse events (AEs) during treatment, treatments after the occurrence of AEs, and changes in Visual Analog Scale (VAS) scores before and after SLIT-sprays. Self-reports from 100 patients were collected. The results showed that the average treatment duration for the 100 patients was (90.7±58.9) days, median 78.5 days. Using changes in VAS scores as the effectiveness assessment, the average VAS score increased by 4.2 (95% CI: 4.06-4.34). The incidence of AEs during the SLIT-sprays was 17.0% (17/100), all of which were mild to moderate local reactions, with no serious AEs reported. There were no significant differences in AE incidence among patients with different diseases (AR or AR with asthma and asthma alone) (χ 2=1.831, P>0.05), different age group (χ 2=1.477, P>0.05), different types of allergen extracts (χ 2=1.613, P>0.05), or the number of allergen extracts used (patients using one or two allergen extracts) (Fisher′s exact test, P>0.05). In conclusion, Chinese patients showed good safety and tolerability to SLIT-sprays, with all AEs being mild to moderate local reactions and no serious or systemic AEs occurring. Patients reported positive subjective evaluations of the early treatment effects.

BACKGROUND:There is a high risk for the elderly cervical spine surgery combined with cerebral infarction, whereas conservative treatment is often unable to resolve serious cervical lesions.
OBJECTIVE:To discuss the surgical effects of anchor fixation via posterior approach on cervical spinal canal stenosis combined with cerebral infarction.
METHODS:A total of 21 patients with cervical spinal canal stenosis combined with cerebral infarction who were admitted over the past 5 years accepted cervical posterior expensive open-door laminoplasty and fixation with wire anchors. Therapeutic effects were evaluated according to the Japanese Orthopaedic Association (JOA) scores.
RESULTS AND CONCLUSION:Al the patients were fol owed up 6 to 24 months, averagely 15 months. Al patients were smoothly through the perioperative period. There were no acute severe cerebral infarction cases. Preoperative JOA score was (7.6±2.0) points averagely, and postoperative JOA score was (13.3±1.8) points averagely, showing a significant difference (P<0.01). Of the 21 patients, excellent effects were in 11 cases and good in 7 cases. The effective rate was 95%(20/21), and the excellent-good rate was 86%(18/21). The risk of surgical treatment of patients with cerebral infarction is higher, but it is not the absolute contraindication. Choosing the proper operation way is highly important. Cervical posterior expensive open-door laminoplasty and fixation with wire anchors can be used to reduce the risk of cerebrovascular accidents to some extent, and obtain an excellent clinical effect.

The concept of epigenetics was first proposed by Waddington in 1942,referring to phenotypic changes that are not related to the underlying DNA sequence,yet alterations in the level and function of gene expression can be heritable,such as DNA methylation,histone modifications,microRNA interference,etc.Phenotype changes while genotype remains unchanged,this controlled mechanism can be kept stable throughout cell division,proliferation,and subsequent process of development.This process thus may cause corresponding changes in the pathophysiology,which are correlated with the occurrence of cancer,immune disorder,cardiovascular disease,metabolic syndrome and so on.Diabetes mellitus is the third heaviest chronic diseases in the world,and does serious harm to human health,especially the diabetic vascular diseases.Even if the blood glucose level is controlled in an ideal state,vascular inflammation still persists,indicating the existence of metabolic memory.Studies have suggested that the pathogenesis can be elucidated at the level of epigenetics.This paper mainly focuses on DNA methylation,histone modifications,and is an overview of epigenetics research progress in diabetic vascular diseases.

Objective To study the expression of interleukin-17 (IL-17) in diabetic rat aorta and the effect of intervention with resveratrol,meanwhile,to explore the potential mechanisms of IL-17 induced diabetic vascular diseases and the protective role played by resveratrol in the epigenetic field.Methods The experiment was carried out in 4 groups:normal control group(NC),normal interventional group(NB),diabetic group(DM),and diabetic interventional group(DB),NB and DB groups were intervened with resveratrol.Immunohistochemistry was used to observe the histological localization of IL-17 and to measure the thickness of rat abdominal aorta.Western blotting,real-time PCR,and methylation-specific PCR were used respectively to compare the expression of IL-17 protein and mRNA,as well as DNA methylation in 4 groups.Results IL-17 mainly expressed in arterial intima of diabetic rats,the abdominal aorta in DM group was obviously thicker than that in NC and DB groups(P＜0.05).IL-17 protein and mRNA expressions in DM group were significantly higher than NC group(P＜0.05),and were reduced in NB and DB groups compared with NC and DM groups respectively.While DNA methylation levels of IL-17 in DM group were significantly lower than NC group(P＜0.01),however,the levels in NB and DB groups were elevated accordingly as compared with corresponding groups.Conclusions The increased levels of IL-17 in aorta of diabetic rats suggests that IL-17 is involved in the process of inflammatory responses to diabetic macrovascular diseases,while resveratrol could inhibit the expression,it may play a role in protecting aorta,and the regulation of IL-17 gene promoter DNA methylation levels may be the potential mechanism underlying these two phenomena.
