A 20-year-old male patient presented to the Department of Dermatology of Peking Union Medical College Hospital with complaints of an 8-year history of facial scarring, swelling of the lower limbs, and a 4-year history of scalp thickening. Physical examination showed thickening furrowing wrinkling of the skin on the face and behind the ears, ciliary body hirsutism, blepharoptosis, and cutis verticis gyrate. Both lower limbs were swollen, especially the knees and ankles. The skin of the palms and soles of the feet was keratinized and thickened. Laboratory examination using bone and joint X-ray showed periostosis of the proximal middle phalanges and metacarpals of both hands, distal ulna and radius, tibia and fibula, distal femurs, and metatarsals.Genetic testing revealed two variants in SLCO2A1, c.1658T > A and c.96+4A > C.Through multidisciplinary consultation, we confirmed the diagnosis of pachydermoperiostosis.

Traditional Chinese medicine(TCM) capable of clearing heat and removing toxin is most commonly used in clinical practice and has the effect of removing fire-heat and toxin. Studies have shown that most of the Ilex plants have the effect of clearing heat and removing toxin, among which the varieties of I. cornuta, I. pubescens, I. rotunda, I. latifolia, and I. chinensis are most widely used. These plants generally contain triterpenoids and their glycosides, alkaloids, flavonoids, phenylpropanoids, and other chemical components, especially pentacyclic triterpenoids. According to their skeletons, pentacyclic triterpenoids can be divided into the oleanane type, the ursane type, the lupinane type, etc. Among them, ursane-type components are the most abundant, and 136 species have been found so far. These components have been proved to have pharmacological effects such as anti-inflammatory, anti-tumor, hypolipidemic, anti-thrombosis, cardiomyocyte-protective, antibacterial, and hepatoprotective effects. Therefore, this paper systematically reviews the domestic and foreign literature on Ilex plants with a focus on the research progress on pentacyclic triterpenoids and their pharmacological activities, aiming to provide reference for the development of TCM resources with the effect of clearing heat and removing toxin.

Acute kidney injury (AKI) is a critical clinical condition characterized by rapid renal function decline, with high morbidity, mortality, and healthcare costs. Traditional Chinese medicine (TCM) has shown potential effects on mitigating oxidative stress and programmed cell death in AKI models. Scutellaria barbata D. Don (SB) and Scleromitrion diffusum (Willd.) R. J. Wang (SD), a classic TCM herbal pair exhibited anti-inflammatory and antioxidant activities. Using advanced chromatographic separation technology, we enriched the effective fractions of water extracts from SB-SD, obtaining self-assembled herbal nanoparticles (SB and SD nanoparticles, SSNPs) rich in flavonoids and terpenoids. These SSNPs demonstrated robust antioxidant properties in vitro and mitigated AKI progression in vivo by activating the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway. Oral administration of SSNPs in mice resulted in absorption into the bloodstream, formation of a protein corona, reduced macrophage phagocytosis, and enhanced bioavailability and renal targeting. Furthermore, we investigated the self-assembly principle of SSNPs using representative flavonoids and terpenoids. Kinetic studies and in situ transmission electron microscopy (in situ TEM) revealed that these compounds self-assemble via supramolecular forces like hydrogen bonding and π-π interactions, forming stable nanostructures. This study elucidates the renoprotective effects and mechanisms of SB and SD, and provides a novel approach for the development of TCM-based nanomedicines, highlighting the potential of nano-TCM in AKI treatment.

Objective To observe the clinical efficacy and safety of ticagrelor tablets combined with atorvastatin calcium tablets in the treatment of cerebral thrombosis.Methods The patients with cerebral thrombosis were divided into control group and treatment group according to cohort methods.Two groups were given basic therapy.On the basic therapy,control group was given atorvastatin calcium 20 mg per time,once a day,orally;on the basic of control group,the treatment group received ticagrelor 90 mg per time,twice a day,orally.Two groups were treated for 4 months.The clinical efficacy,nerve function,blood viscosity,platelet parameters,brain injury markers and adverse drug reactions were compared between two groups.Results Treatment and control groups enrolled 119 and 117 cases,respectively.After treatment,the total effective rates of treatment and control groups were 91.60％(109 cases/119 cases)and 82.05％(96 cases/117 cases)with significant difference(P＜0.05).After treatment,the scale scores of treatment and control groups were(5.47±0.82)and(6.51±0.96)points;the plasma viscosity levels were(1.35±0.21)and(1.62±0.24)mPa·s,whole blood high shear viscosity levels were(3.67±0.51)and(4.01±0.59)mPa·s;the whole blood low shear viscosity levels were(6.12±0.93)and(7.05±1.07)mPa·s;the platelet adhesion rates were(30.52±3.81)％and(36.21±4.02)％;the mean platelet volumes were(12.75±1.86)and(15.42±2.06)fL;the carboxy-terminal hydrolase of ubiquitin levels were(0.39±0.06)and(0.51±0.07)μg·L-1;the key protein antigen-5 of aging levels were(90.76±12.23)and(81.64±11.95)μg·L-1;and the differences were statistically significant between two groups(all P＜0.05).The adverse drug reactions of two groups were nausea,vomiting,bleeding,abdominal pain and diarrhea.The total incidences of adverse drug reactions in treatment and control groups were 5.04％and 4.27％,without significant difference(P＞0.05).Conclusion Ticagrelor tablets combined with atorvastat in calcium tablets have a significant clinical efficacy in the treatment of patients with cerebral thrombus,which can significantly improve the neurological function,blood viscosity,brain injury markers,and platelet parameters of patients,without increasing the incidence of adverse drug reactions.

Cerebrospinal fluid morphology examination is an important method of diagnosing central nervous system diseases, but manual microscopy has shortcomings such as low efficiency, long staff training period, and poor homogeneity of test results. In recent years, the application of artificial intelligence in the medical field has developed rapidly, providing new technical means for cerebrospinal fluid morphology examination. In the future, AI-assisted morphological examination of cerebrospinal fluid will not only realize digitalization and networking, but also improve the level and efficiency of intelligent diagnosis of cerebrospinal fluid morphology, which has a broad application prospect in the intelligent assisted diagnosis of cerebrospinal fluid.

The update of Guidelines for Diagnosis and Management of chronic coronary syndrome(CCS)of the European Society of Cardiology(ESC)in 2024 is as follows:(1)Changes in content and form;(2)the latest definition of CCS;(3)Refined diagnostic method of CCS;(4)Recognized revascularization strategies by surgeon in patients with left main artery disease or multi-vessel coronary artery disease;(5)The importance of microvascular dysfunction;(6)Other recommendation for treatment of angina pectoris,antithrombotic therapy and statins.The core of the 2024 ESC guideline is to comprehensively deal with the traditional large artery obstruction and new problems related to microvascular dysfunction,and to emphasize the importance of individualized strategies.

More and more evidence shows that non-epicardial coronary causes of angina pectoris and ischemia,including coronary microvascular dysfunction,vasospasm disorder and myocardial metabolic disorder,are more common than blood flow limited stenosis.Therefore,in 2019,the European Society of Cardiology(ESC)guideline first proposed the concept of chronic coronary syndrome to replace the diagnostic terminology of stable coronary artery disease(SCAD).The 2024 ESC guideline further clarified the definition of chronic coronary syndrome.Recently,American Heart Association and ESC suggested renaming the diagnostic term of SCAD as non-acute myocardial ischemia syndrome.These reflect the deepening understanding of the pathophysiology of SCAD,which will certainly bring about further accurate classification of SCAD and better guide clinical practice.
