Objective:To observe the effect of epalrestat on the heart rate variability in diabetes patients with silent myocardial is-chemia. Methods:Totally 60 patients were randomly divided into the control group and the treatment group with 30 cases in each. The two groups were given insulin or other routine drugs to keep blood sugar under control, ARB or ACEI and CCB to bring high blood pres-sure down, and statins to regulate lipid and anti-platelet aggregation, and both groups were without the use of beta blockers. The treat-ment group was given epalrestat 50mg three times a day for 4 weeks additionally. The indices of FPG, 2hPG, HbA1c, SBP, DBP, T-CHOL, TG, HDL-C, LDL-C and heart rate variability were observed after the treatment. Results: Compared with those before the treatment, the values of FPG, 2HPG, HbA1C, SBP, DBP, T-CHOL and LDL-c were decreased after the treatment in the two groups, and the differences were statistically significant (P <0.05), while the differences between the two groups were not obvious(P >0. 05). After the treatment, SDNN, SDANN, SDNNI, RMSSD, PNN50 and Mean HR in the treatment group were obviously im-proved, which were better than those in the control group (P<0.05). The adverse reactions in the two groups were similar (P<0. 05). Conclusion:Epalrestat can significantly improve HRV-related indicators in the diabetes patients with silent myocardial ischemi-a, which can reduce the risk of sudden death without significant adverse reactions in the combination with other drugs.

Lung cancer is the top cause of cancer deaths globally.Advances in immune checkpoint inhibitors(ICIs)have transformed cancer treatment,but their use in lung cancer has led to more side effects.This study examined if past pulmonary tuberculosis(TB)affects ICIs'effectiveness and safety in lung cancer treatment.We reviewed lung cancer patients treated with ICIs at Beijing Chest Hospital from January 2019 to August 2022.We compared outcomes and side effects between patients with and without prior TB.Of 116 patients(40 with TB history,76 without),prior TB didn't reduce treatment effectiveness but did increase severe side effects.Notably,older patients(≥65 years)faced a higher risk of severe side effects.Detailed cases of two patients with severe side effects underscored TB as a risk factor in lung cancer patients receiving ICIs,stressing the need for careful monitoring and personalized care.

Objective:To systematically integrate the experience and feelings of informal caregivers of patients with intracranial tumors.Methods:Qualitative researches on the real experience and inner needs of informal family caregivers of patients with intracranial tumors were retrieved in the PubMed, Web of Science, China National Knowledge Infrastructure (CNKI) , WanFang Data, China Biomedical Database and VIP Chinese Journal Database by computer. The search time was from the establishment of the database to May 31, 2021. After screening and analysis, the critical appraisal tool for qualitative research (2017) of the Joanna Briggs Institute (JBI) Evidence-based Health Center in Australia were used to evaluate the articles and the results were Meta-integrated.Results:A total of 14 articles meeting the criteria were included. A total of 48 complete research themes were refined, and they were summarized and combined to form 3 comprehensive Meta-integration results and 4 new categories. The 3 Meta-integration results were that the caregiver experienced the shock, sadness, disbelief and hope in the early stage of diagnosis, and began to assume responsibility and learn to become a caregiver's psychological and emotional changes; the caregiver's family role and living environment changed, affecting the quality of life of caregivers; caregivers lacked information, care experience and social support.Conclusions:The quality of life of informal caregivers of patients with intracranial tumors and the changes in family functions have attracted attention. Social and medical workers should combine our country's cultural background to formulate effective intervention strategies and related health policies for the difficulties and challenges faced by this special population.

Objective:To investigate the value of MRI in diagnosing the high expression of transcription factor E2F2 in breast cancer, in order to further evaluate the biological aggressiveness of breast cancer.Methods:The study was cross-sectional. The clinical and imaging data of 92 patients with breast cancer who were pathologically diagnosed in the Second Affiliated Hospital of Nantong University from October 2014 to December 2020 were retrospectively analyzed. All patients were female, aged 32 to 82 (56±11) years. All patients underwent MRI, including T 1WI, T 2WI, diffusion-weighted imaging (DWI), and dynamic enhanced MRI. According to the immunohistochemical results, the patients were divided into E2F2 high expression group and E2F2 low expression group. Independent sample t test, Mann-Whitney U test or χ2 test were used to compare the clinical data, MRI features and pathological features of the two groups. Characteristics with P≤0.1 from univariate analyses were included in multivariate logistic regression to screen for independent risk factors predicting high expression of the transcription factor E2F2 in breast cancer. Results:Among 92 patients, 68 were in the high E2F2 expression group and 24 were in the low E2F2 expression group. There were significant differences between the two groups in peritumoral edema, type composition ratio of time-signal intensity curve, estrogen receptor expression, human epidermal growth factor receptor 2 expression, endovascular cancer embolus and molecular type composition ratio (all P<0.05). Multivariate logistic regression analysis showed that peritumoral edema alone ( OR=7.061, 95% CI 1.837—27.144, P=0.004) was an independent risk factor for predicting the high expression of transcription factor E2F2 in breast cancer. Conclusion:MRI show that peritumoral edema is an independent risk factor for predicting high expression of the breast cancer transcription factor E2F2, which is associated with the aggressiveness of breast cancer.
