Abdominal aortic aneurysm (AAA) is a deadly condition of the aorta, carrying a significant risk of death upon rupture. Currently, there is a dearth of efficacious pharmaceutical interventions to impede the advancement of AAA and avert it from rupturing. Here, we investigated dihydromyricetin (DHM), one of the predominant bioactive flavonoids in Ampelopsis grossedentata (A. grossedentata), as a potential agent for inhibiting AAA. DHM effectively blocked the formation of AAA in angiotensin II-infused apolipoprotein E-deficient (ApoE^-/-) mice. A combination of network pharmacology and whole transcriptome sequencing analysis revealed that DHM's anti-AAA action is linked to heme oxygenase (HO)-1 (Hmox-1 for the rodent gene) and hypoxia-inducible factor (HIF)-1α in vascular smooth muscle cells (VSMCs). Remarkably, DHM caused a robust rise (∼10-fold) of HO-1 protein expression in VSMCs, thereby suppressing VSMC inflammation and oxidative stress and preserving the VSMC contractile phenotype. Intriguingly, the therapeutic effect of DHM on AAA was largely abrogated by VSMC-specific Hmox1 knockdown in mice. Mechanistically, on one hand, DHM increased the transcription of Hmox-1 by triggering the nuclear translocation and activation of HIF-1α, but not nuclear factor erythroid 2-related factor 2 (NRF2). On the other hand, molecular docking, combined with cellular thermal shift assay (CETSA), isothermal titration calorimetry (ITC), drug affinity responsive target stability (DARTS), co-immunoprecipitation (Co-IP), and site mutant experiments revealed that DHM bonded to HO-1 at Lys243 and prevented its degradation, thereby resulting in considerable HO-1 buildup. In summary, our findings suggest that naturally derived DHM has the capacity to markedly enhance HO-1 expression in VSMCs, which may hold promise as a therapeutic strategy for AAA.

Purpose To investigate the clinicopathological features,diagnosis,differential diagnosis and molecular charac-teristics desmoid fibromatosis the breast(DFB).Methods The clinicopathological data and prognostic information of 26 pa-tients with desmoid fibromatosis of the breast were collected.Their clinical characteristics,histological morphologies,immu-nophenotypes and molecular characteristics were analyzed.Re-sults All the 26 patients were female,with a median age of 34.5 years and an average age of 36.8 years(range from 13 to 69 years).There were 10 cases in left breast,14 cases in right breast and 2 cases in bilateral breast.Isolated and painless breast masses were found in all patients,and 3 cases were ac-companied by nipple depression.Grossly,most of them showed a poorly circumscribed tan-white to gray mass with a trabeculated appearance.Microscopically,all the tumors were composed of mild spindle cells with varying intervals of collagen fiber bun-dles.The boundary between the tumor and the surrounding breast tissue was not clear,and the tumor cells infiltrated adja-cent tissues,such as breast ducts,lobules,adipose tissue,and skeletal muscle.Uniform spindle or oval cells formed in fascicles and interwoven,without atypical or polymorphism;the nuclear chromatin was sparse or vacuolar,with small nucleoli,but mito-ses were rare or absent.Nuclear accumulation of β-catenin was present in 20 of 26 tumors,SMA was variously positive in 20 of 26,desmin was focally positive in 6 of 26;CKpan,CK5/6,p63,CD34,CD10 and S-100 were all negative.The Ki67 index was 5％-10％.The gene mutations of CTNNB1 exon 3 were found in 18 of 26 by Sanger sequencing,including T41A(83.3％),S45P(11.1％)and S45F(5.6％).Two patients also had familial adenomatous polyposis.Local resection was performed in 23 cases,mastectomy was performed in 2 cases,and one case did not require any additional treatment after core needle biopsy.20 cases were followed up for 1-108 months,and no recurrence occurred.Conclusion Desmoid fibromatosis of the breast is rare,and can mimic breast cancer clinically,ra-diologically and histologically.It should be always considered in differential diagnosis for the spindle cell proliferations of the breast.A diagnosis of DFB can be achieved basing on the typi-cal histopathology,immunohistochemistry,history and gene se-quencing.

Bioactive compounds derived from herbal medicinal plants modulate various therapeutic targets and signaling pathways associated with cardiovascular diseases (CVDs), the world's primary cause of death. Ginkgo biloba, a well-known traditional Chinese medicine with notable cardiovascular actions, has been used as a cardio- and cerebrovascular therapeutic drug and nutraceutical in Asian countries for centuries. Preclinical studies have shown that ginkgolide B, a bioactive component in Ginkgo biloba, can ameliorate atherosclerosis in cultured vascular cells and disease models. Of clinical relevance, several clinical trials are ongoing or being completed to examine the efficacy and safety of ginkgolide B-related drug preparations in the prevention of cerebrovascular diseases, such as ischemia stroke. Here, we present a comprehensive review of the pharmacological activities, pharmacokinetic characteristics, and mechanisms of action of ginkgolide B in atherosclerosis prevention and therapy. We highlight new molecular targets of ginkgolide B, including nicotinamide adenine dinucleotide phosphate oxidases (NADPH oxidase), lectin-like oxidized LDL receptor-1 (LOX-1), sirtuin 1 (SIRT1), platelet-activating factor (PAF), proprotein convertase subtilisin/kexin type 9 (PCSK9) and others. Finally, we provide an overview and discussion of the therapeutic potential of ginkgolide B and highlight the future perspective of developing ginkgolide B as an effective therapeutic agent for treating atherosclerosis.

Lymphatic metastasis is the main metastatic route for colorectal cancer, which increases the risk of cancer recurrence and distant metastasis. The properties of the lymph node metastatic colorectal cancer (LNM-CRC) cells are poorly understood, and effective therapies are still lacking. Here, we found that hypoxia-induced fibroblast activation protein alpha (FAPα) expression in LNM-CRC cells. Gain- or loss-function experiments demonstrated that FAPα enhanced tumor cell migration, invasion, epithelial-mesenchymal transition, stemness, and lymphangiogenesis via activation of the STAT3 pathway. In addition, FAPα in tumor cells induced extracellular matrix remodeling and established an immunosuppressive environment via recruiting regulatory T cells, to promote colorectal cancer lymph node metastasis (CRCLNM). Z-GP-DAVLBH, a FAPα-activated prodrug, inhibited CRCLNM by targeting FAPα-positive LNM-CRC cells. Our study highlights the role of FAPα in tumor cells in CRCLNM and provides a potential therapeutic target and promising strategy for CRCLNM.

Purpose To investigate the clinicopathological features,molecular genetics and prognosis of high grade B cell lymphoma with concurrent MYC rearrangement and 11q aberra-tions(HGBCL-MYC-11q).MethodsThree cases of HGBCL-MYC-11q were reviewed and analyzed using hematoxylin-eosin staining,immunohistochemistry,EBER in situ hybridization and fluorescence in situ hybridization.Clinical data were collected with follow-up.Results All three patients were male,age was 10,61,and 74 years,respectively.All patients had Ann Arbor stage Ⅳ disease.All three cases were biopsies occurring in the nasopharynx,upper pharynx and ileocecus,respectively.Three cases were morphologically similar to diffuse infiltrative growth of tumor cells,moderate or moderately large cells,round to slightly irregular nuclei and easily visible mitotic figures.Focal necrosis was noted in one case.One case exhibited the distinct"starry sky"pattern.All cases expressed CD20,BCL6 and MUM1 and high Ki67 index,two cases expressed CD10 and two cases ex-pressed BCL2.CD3,CD30 and TDT were all negative.EBER in situ hybridization was all negative.FISH analyses using C-MYC break-apart probes were all positive and all cases had 11q aberrations.One case only had the 11q23.3 amplification;and one case only had the 11q24.3 loss.After a follow-up for 1-18 months,one patient died and two patients survived with disease.ConclusionHGBCL-MYC-11q is rare,morphologically similar to BL/HGBCL,with MYC rearrangement and 11q abnormali-ties.We should enhance awareness of the disease and improve more accurate diagnosis and differential diagnosis of the disease.

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.

Bone organoids can simulate the complex structure and function of the bone tissues, which makes them a frontier technology in organoid researches. Bone organoids show a tremendous potential of applications in bone disease modeling, bone injury repair, and medicine screening. Although advancements have been made so far in constructing bone organoids with functional structures like mineralization, bone marrow, trabecular bone, callus, woven bone, etc, the researches in this field are confronted with numerous challenges such as lack of standardized construction strategies and unified evaluation criteria, which limits their further promotion and application. To standardize researches in bone organoids, the Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, the Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, the Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and the Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine organized related experts to formulate Expert consensus on the construction, evaluation, and application of bone organoids ( version 2024) based on an evidence-based approach. A total of 17 recommendations were put forth, aiming to standardize researches and clinical applications of bone organoids and enhance their value in scientific research and clinical practice.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

Objective To investigate the effect of Kunxian capsule combined with candesartan axetil on blood pressure, renal function, blood lipids and inflammatory factors in patients with chronic glomerulonephritis complicated with hypertension. Methods 101 patients with chronic glomerulonephritis who were admitted to our hospital from November 2017 to December 2019 were selected and randomly divided into observation group (51 cases) and control group (50 cases). The control group was treated with candesartan cilexetil on the basis of conventional treatment, and the observation group was treated with Kunxian capsule on the basis of the control group. The clinical efficacy and adverse reactions of the two groups were compared. Results The total effective rate of the observation group was significantly higher than that of the control group (P<0.05). After treatment, the blood pressure, renal function indexes (24 h Upro, BUN, Scr), blood lipid indexes (TG, TC, LDL-C), and inflammatory factors of the two groups (IL-6, hs-CRP) significantly decreased, and the observation group was significantly lower than the control group (P<0.05). After treatment, the blood lipid index HDL-C of the two groups increased significantly, and the blood lipid index HDL-C of the observation group was significantly higher than that of the control group (P<0.05). Conclusion Kunxian capsule combined with candesartan axetil can enhance the clinical efficacy, improve renal function, regulate blood lipids and reduce inflammation in patients with chronic glomerulonephritis complicated with hypertension.
