Objective To explore the predictive value of contrast-enhanced echocardiography com-bined with serum levels of CD137 and insulin-like growth factor binding protein 6(IGFBP-6)for cardiovascular adverse events(MACE)in elderly patients with stable coronary heart disease(CHD)after percutaneous coronary intervention(PCI).Methods A total of 108 elderly patients with stable CHD(CHD group)who visited Department of Cardiology of Changsha First Hospital from March 2020 to March 2022 were recruited in this study.They were grouped into a non-MACE group(81 cases)and a MACE group(27 cases)according to whether MACE occurred after PCI.Another 100 healthy individuals who taking physical examination during the same period served as control group.Their serum CD137 and IGFBP-6 levels were detected,and the contrast agent filling speed(β value)and maximum number of microbubbles(A value)were calculated based on the results of contrast-enhanced echocardiography.Their general clinical data were col-lected.ROC curve analysis and multivariate logistic regression analysis were used to analyze the data.Results The serum levels of CD137 and IGFBP-6 were significantly higher,while the β value and A value were obviously lower in the CHD group than the control group(P＜0.01).And the serum levels were notably higher,and the β value and A value were remarkably lower in the MACE group than the non-MACE group(P＜0.01).The AUC of cardiac ultrasound parameters βvalue and A value combined with serum CD137 and IGFBP-6 to predict MACE after PCI in CHD patients was 0.930,which was significantly higher than the AUC value of every single indicator(P＜0.01).β value,A value,CD137 and IGFBP-6 levels were all risk factors for the occurrence of MACE in CHD patients after PCI(P＜0.01).Conclusion Contrast-enhanced echocardiography,serum CD137 and IGFBP-6 levels have certain predictive value for MACE in elderly CHD patients after PCI,and combined detection has higher predictive value.

The aim of this study was to investigate the effect of norcantharidin (NCTD) on the proliferation and apoptosis of triple-negative breast cancer cell line MDA-MB-231.Western blot was used to detect the effect of NCTD on the expression levels of apoptosis-related proteins Bax/Bcl-2, cleaved-PARP/PARP/PARP, cleved-caspase-9, cleaved-caspase-3 and MCL-1 in MDA-MB-231 cells.Also, the expression levels of autophagy-related proteins LC3-II/LC3-I, Parkin and PINK1 in MDA-MB-231 cells were measured by Western blot.Flow cytometry was used to measure the effect of NCTD on the changes of mitochondrial membrane potential and mitochondrial reactive oxygen species (ROS).The effect of NCTD on autophagy flow in cells expressing mCherry-EGFP-LC3 was detected by a confocal microscope.Moreover, the effects of NCTD combined with chloroquine (CQ) or 3-methyladenine (3-MA) on the apoptosis of MDA-MB-231 cells were detected by flow cytometry.The results showed that NCTD significantly increased the expression levels of Bax/Bcl-2, cleaved-PARP/PARP, cleaved-caspase-9, cleasved-caspase-3 and LC3-II/LC3-I proteins, and promoted the mitochondrial translocation of Parkin, and blocked the autophagic flow in MDA-MB-231 cells. Moreover, NCTD combined with CQ accelerated apoptosis, while NCTD combined with 3-MA decreased apoptosis.These results suggest that NCTD can induce autophagy accumulation and lead to apoptosis of MDA-MB-231 cells.

OBJECTIVES: To determine the association between glycosylated hemoglobin (HbA1c) and ambulatory blood pressure or heart rate in hypertensive patients. METHODS: A total of 585 patients, who performed ambulatory blood pressure monitoring (ABPM) from September 2018 to April 2019 in Xiangya Hospital, Central South University, were enrolled and assigned into 2 groups (470 in a hypertensive group and 115 in a normal group). HbA1c levels were compared. According to the HbA1c level, the hypertensive group was divided into 2 subgroups: A high HbA1c group (HbA1c≥6.1%, RESULTS: The hypertensive group had higher HbA1c level than the normal group [(6.1±1.3)% vs (5.1±1.7)%, CONCLUSIONS In hypertensive patients, HbA1c is positively correlated with ambulate blood pressure, blood pressure load, and heart rate, and it has no correlation with blood pressure variability, heart rate variability, or morning blood pressure.

The current document is based on a consensus reached by a panel of experts from the Chinese Society of Allergy and the Chinese Society of Otorhinolaryngology-Head and Neck Surgery, Rhinology Group. Chronic rhinosinusitis (CRS) affects approximately 8% of Chinese adults. The inflammatory and remodeling mechanisms of CRS in the Chinese population differ from those observed in the populations of European descent. Recently, precision medicine has been used to treat inflammation by targeting key biomarkers that are involved in the process. However, there are no CRS guidelines or a consensus available from China that can be shared with the international academia. The guidelines presented in this paper cover the epidemiology, economic burden, genetics and epigenetics, mechanisms, phenotypes and endotypes, diagnosis and differential diagnosis, management, and the current status of CRS in China. These guidelines—with a focus on China—will improve the abilities of clinical and medical staff during the treatment of CRS. Additionally, they will help international agencies in improving the verification of CRS endotypes, mapping of eosinophilic shifts, the identification of suitable biomarkers for endotyping, and predicting responses to therapies. In conclusion, these guidelines will help select therapies, such as pharmacotherapy, surgical approaches and innovative biotherapeutics, which are tailored to each of the individual CRS endotypes.

Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2–3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of original articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.
