Objective To evaluate the effect of Intravascular lithotripsy(IVL)in the treatment of calcified nodules,and to observe the presence of coronary dissection after IVL treatment.Methods A total of 106 patients with coronary atherosclerotic heart disease(coronary heart disease)admitted to the cardiovascular Department of Shougang Hospital,Peking University from March 2023 to July 2024 were retrospectively analyzed.A total of 106 patients with moderate to severe stenosis accompanied by calcification as detected by coronary angiography were treated with IVL after intravascular ultrasound(IVUS)examination.Patients were divided into two groups according to whether there were calcified nodules in the coronary lesions:39 cases in the calcified nodules group and 67 cases in the non-calcified nodules group.The occurrence of coronary dissection during surgery was observed between the two groups,and other perioperative related complications and major adverse cardiovascular events(MACE)within 1 month after percutaneous coronary intervention(PCI)were compared between the two groups.Results The levels of renal insufficiency(25.6％vs.9.0％,P=0.021)and creatinine[(119.71±134.75)μmol/L vs.(71.82±16.53)μmol/L,P=0.033]in the calcified nodule group were higher than those in the non-calcified nodule group,the difference was statistically significant,and there was no difference in other baseline data.The target vessels in the calcified nodule group were mainly left anterior descending branch and right coronary artery,while those in the non-calcified nodule group were mainly left anterior descending branch,with few circumflex branches in both groups,and there was statistical significance in the distribution of target vessels in the left anterior descending branch and right coronary artery between the two groups(P=0.020).In terms of eccentric calcification(P=0.048)and asymmetric calcification(48.7％vs.28.4％,P=0.035)between the two groups,the calcified nodule group was higher than the non-calcified nodule group,the difference was statistically significant(P＜0.05).In terms of whether more than 20 pulses were needed and whether there was slippage during IVL,the calcified nodule group was higher than the non-calcified nodule group,the difference was statistically significant(P=0.022).The success rate of interventional therapy was 100％in both groups.After IVL treatment,the calcified nodule group was higher than the non-calcified nodule group in terms of the occurrence of coronary artery dissection,the difference was statistically significant(P＜0.009).The MACE of the two groups within 1 month after PCI was slightly higher in the calcified nodule group than in the non-calcified nodule group,but the difference was not statistically significant(P=0.235).Conclusions IVL is feasible and effective for the treatment of calcified coronary nodules.However,in the course of treatment,the occurrence of coronary dissection should be vigilant,identified as early as possible,and treated in time.

Dark plum can be used to treat symptoms such as consumptive thirst due to deficiency-heat and chronic cough due to lung deficiency.Its active ingredients have auxiliary effects on lowering blood glucose,antibacterial and anti-inflammatory activities.Insulin resistance is mainly characterized by the weakening of the physiological effects of insulin in the body,with a relatively complex mechanism that can lead to various metabolic-related diseases and seriously affect health.The active ingredients of dark plum can improve insulin resistance by regulating insulin signaling pathways,endoplasmic reticulum stress,antioxidant stress,inflammatory signaling pathways,levels of related inflammatory mediators,and free fatty acid levels.By reviewing the relevant literature on the improvement of insulin resistance by the active ingredients of dark plum,this article summarizes and analyzes its mechanism of action,aiming to provide new ideas and scientific evidence for in-depth research on insulin resistance and the development and application of drugs.

The lesion of the left main coronary artery(LM)itself is one of the challenges of interventional therapy.If the lesion is combined with calcification,the interventional therapy is difficult to operate and extremely risky.This case report presents a 77-year-old elderly male patient.Coronary angiography(CAG)indicated severe stenosis of the LM-left anterior descending(LAD)accompanied by severe calcified bifurcation lesions.After pre-dilation,percutaneous coronary intraluminal shock wave balloon catheter angioplasty(IVL)was applied for treatment.Before IVL treatment,the LM-LAD lesion was subjected to ischemic preconditioning by using an appropriate balloon to fix the pressure and gradually upgrading the balloon dilation time.Later,a Cross-over procedure was performed to implant a single stent,achieving satisfactory results.Among them,the ischemic preconditioning methods for LM lesions can provide reference significance for clinicians.

Aim To clarify the mechanism by which Qishen Yixin Granules improved microcirculation vas-cular endothelial dysfunction(VED)in mice,through activating the Nrf2/HO-1 signaling pathway to regulate oxidative stress.Methods C57 mice were randomly divided into six groups:blank group,model group,pos-itive drug group,and low-,medium-,and high-dose groups of Qishen Yixin Granules.The VED model was established by long-term infusion of Ang Ⅱ combined with a high-fat diet.Each treatment group received the corresponding drug intervention.After four weeks of drug intervention,cardiac function was assessed by echocardiography.Carstairs staining was used to ob-serve the formation of microthrombi in myocardial tis-sue.The micro vascular ischemia was evaluated by Hei-denhain staining.The ultrastructure of endothelial cells was observed by electron microscopy.The levels of EMPs,ROS,NO,ET-1,TF,TM,VWF,and TXA2 in serum were measured by ELISA.The expression levels of MDA,SOD,and GSH-Px in mouse heart tissue were determined by chemical methods.Cardiac microvascu-lar density and the expression of Nrf2,Keap1,and HO-1 proteins were detected by Immunohistochemical stai-ning.The protein expressions of Keap1,cytoplasmic Nrf2,nuclear Nrf2,and HO-1 in myocardial tissue were detected by Western blot.Results Qishen Yixin Granules could effectively improve the cardiac function of mice,alleviate the damage of endothelial cells and endothelial function.They could up-regulate serum NO levels and the activities of antioxidant enzymes SOD and GSH-Px,while down-regulating the expression of ROS and vascular inflammatory injury factors such as ET-1,VWF,TXA2,TF,TM,and EMPs.Qishen Yixin Granules also increased the positive counts of CD34,Nrf2,and HO-1,as well as microvessel density.Fur-thermore,they inhibited the expression of MDA,Keap1,and cytoplasmic Nrf2 protein in myocardial tis-sue,while increasing the expression of nuclear proteins HO-1 and Nrf2.Conclusions Qishen Yixin Granules may inhibit oxidative stress and inflammatory response by regulating the Nrf2/HO-1 signaling pathway,thereby improving vascular endothelial damage and cardiac function in VED mice.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Objective: To describe the prevalence of alcohol consumption and the burden of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption in adults aged ≥20 years in 31 provinces in China from 2005 to 2018. Methods: Data from several national representative surveys was used to estimate provincial alcohol exposure level of adults aged ≥20 years from 2005 to 2018 by using kriging interpolation and locally weighted regression methods. Global disease burden research method and data, and China's death cause surveillance data were used to calculate the population attributable fraction (PAF) of hemorrhagic stroke and hypertensive heart disease and the deaths due to alcohol consumption in men and women aged ≥20 years in 31 provinces in China. China census data of 2010 were used to calculate the attributable standardized mortality rate. Results: In 2005 and 2018, the prevalence of alcohol consumption was 58.7% (95%CI: 57.8%-59.5%) and 58.4% (95%CI: 57.6%-59.3%), respectively, in men and 17.0% (95%CI: 16.6%-17.4%) and 18.7% (95%CI:18.1%-19.3%), respectively, in women. The daily alcohol intake was 24.6 (95%CI: 23.8-25.3) g and 27.7 (95%CI: 26.8-28.7) g, respectively, in men and 6.3 (95%CI: 6.0-6.5) g and 5.3 (95%CI: 5.0-5.6) g, respectively, in women. Alcohol exposure level was higher in the provinces in central and eastern China than in western provinces. The lowest exposure level was found in northwestern provinces. From 2005 to 2018, the PAF of hemorrhagic stroke death due to alcohol consumption increased from 5.5% to 6.8%, the attributable deaths increased from 50 200 to 59 100, while the PAF of hypertensive heart disease death due to alcohol consumption increased from 7.0% to 7.7%, the attributable deaths increased from 15 200 to 29 300. The PAF of hypertensive heart disease and hemorrhagic stroke was higher in men than in women, and in central and eastern provinces than in western provinces. In 2018, the standardized mortality rates of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption were 4.58/100 000 and 2.11/100 000, respectively. Conclusions: The prevalence of alcohol consumption in men and daily alcohol intake of drinkers were relatively high in China, especially in eastern provinces. Alcohol exposure level was lower in women than in men. Regional measures should be taken to reduce the alcohol intakes in men and current drinkers in order to reduce the health problems caused by alcohol consumption.
