Myocardial infarction （MI） and osteoporosis （OP）， as two prevalent metabolic diseases with high morbidity and mortality rates， are respectively characterized by cardiovascular system dysfunction and bone homeostasis imbalance， collectively posing significant global public health challenges. While clinically often considered as independent diseases， recent studies have revealed shared pathological mechanisms between the two. This study initiated its exploration from the traditional Chinese medicine concept of the "heart-bone" axis， systematically analyzing the correlation between MI and OP from perspectives including hemodynamics， neuroendocrinology， calcium homeostasis， inflammation and vascular injury， as well as hormone levels. By discussing the pathological mechanisms of "heart disease affecting the bones and bone disease affecting the heart"， the study also elucidated advancements in both Western and traditional Chinese medicine treatments. The goal is to provide novel insights and methodologies for the prevention and treatment of "heart-bone comorbidities"， thereby facilitating comprehensive management of cardiovascular and skeletal diseases.

Narcotic plants are strictly regulated worldwide due to their ability to extract drug alkaloids and drug precursor components. Besides the three traditional core species, cannabis, opium poppy, and coca, the misuse of psychoactive plants with addictive properties has become increasingly prevalent globally in recent years, and the establishment of accurate identification methods for such plants has become an urgent need in the field of narcotics control. Within existing identification frameworks, the conventional morphological and chemical analysis methods, despite their long-term application, have demonstrated considerable limitations. In contrast, DNA-based molecular identification techniques have achieved significant advancement in recent years due to their high specificity and stability. This review comprehensively examines current DNA-based identification approaches for narcotic plants through three key dimensions: DNA molecular marker technology, DNA barcoding technology, and emerging molecular biological techniques, and elaborates on the principles, technical characteristics, application scenarios, and research progress of each technology, providing some reference for the scientific selection of DNA identification strategies for narcotic plants in different specific scenarios.

Background Silicosis is a fatal form of pulmonary fibrosis caused by the inhalation of silica dust. Although the underlying pathogenesis remains unclear, and the macrophage-mediated immune response plays a central role in its development. Objective To investigate the expression, functional role, and upstream regulatory mechanism of C-C motif chemokine ligand 22 (CCL22) in silica-induced pulmonary fibrosis. Methods Through bioinformatics analysis, we identified CCL22 as a potential key factor in pulmonary fibrosis. We established in vitro models by stimulating human monocytic leukemia cells (THP-1) and peripheral blood mononuclear cell-derived macrophages (PBMC-m) with crystalline silica (CS). The regulation of CCL22 expression by CS was validated using quantitative real-time polymerase chain reaction (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA). Subsequently, a conditioned co-culture system comprising macrophages and lung epithelial cells (BEAS-2B) was developed to evaluate the effects of CCL22 on lung epithelial cell function. Furthermore, the molecular mechanisms underlying CS-induced CCL22 secretion by macrophages were investigated using bioinformatics analysis, Western blot, specific inhibitors, qRT-PCR, and ELISA. Results Bioinformatics analysis identified CCL22 as a key upregulated molecule in pulmonary fibrosis. In vitro experiments confirmed that CS treatment significantly enhanced CCL22 mRNA transcription and protein secretion in THP-1 and PBMC-m cells (P<0. 0001). In the co-culture system, supernatant from CS-stimulated macrophages with stable CCL22 knockdown significantly inhibited the scratch-healing ability and fibrotic process of BEAS-2B cells, and reversed the epithelial-mesenchymal transition (EMT) phenotype compared to the control group. Mechanism studies found that, compared to other transcription factors such as signal transducer and activator of transcription 3 (STAT3) and nuclear factor-κB (NF-κB), the inhibition of of specific protein 1 (SP1) most significantly attenuated the CS-induced upregulation of CCL22. Furthermore, pathway inhibition experiments demonstrated that inhibiting extracellular signal-regulated kinase (ERK) reduced both CCL22 expression and p-SP1. Conversely, SP1 intervention did not affect ERK activation. Conclusion CS promotes CCL22 secretion by macrophages through the Raf/ERK-Sp1 signaling pathway, thereby driving fibrotic changes in pulmonary epithelial cells.

Objective To investigate the prevalence of comorbid chronic diseases among advanced schistosomiasis patients in Suzhou City, so as to provide insights into formulation of the scheme for medical assistance management of advanced schistosomiasis patients. Methods All data pertaining to survival advanced schistosomiasis patients in Suzhou City were retrieved from the Information Management Platform of Schistosomiasis (Parasitic Diseases) in Jiangsu Province as of August 19, 2024. These patients' outpatient and inpatient records from January 1, 2017, to August 19, 2024, were collected through Suzhou Municipal Health Statistics Information Center. The prevalence of comorbid chronic diseases was analyzed, and the comorbid patterns of chronic diseases were identified using cluster analysis. Results A total of 1 868 advanced schistosomiasis patients were enrolled in Suzhou City, with a mean age of (79.20 ± 7.17) years, and the median types of prevalent comorbid chronic diseases was 5 (interquartile range, 5). The mean age [(80.13 ± 7.09) years vs. (77.49 ± 7.02) years; t = 7.70, P < 0.001] and median types of prevalent comorbid chronic diseases [5 (interquartile range, 4) vs. 4 (interquartile range, 5); Z = 436 745, P < 0.001] were both higher among female advanced schistosomiasis patients than among male cases. The prevalence of comorbid chronic diseases was 84.96% (1 587/1 868) among advanced schistosomiasis patients in Suzhou City, and the prevalence was higher among female cases than among male cases [86.58%, (1 052/1 215) vs. 81.93% (535/653); χ² = 7.20, P = 0.007]. The prevalence of comorbid chronic diseases appeared a tendency towards a rise with age among male advanced schistosomiasis patients (χ²_trend = 7.63, P = 0.006) and a decline among female patients (χ²_trend = 10.59, P = 0.001). The prevalence of comorbid chronic diseases was higher among female advanced schistosomiasis patients at ages of 70 to 80 years than among male cases at the same age group [90.18% (459/509) vs. 80.61% (266/330); χ² = 14.81, P < 0.001]. The three most common comorbid chronic diseases included hypertension (67.83%), chronic gastric disorders (57.28%) and heart disease (44.00%) among advanced schistosomiasis patients in Suzhou City. The comorbidity rates of chronic gastric diseases (χ² = 5.33, P < 0.05), heart diseases (χ² = 4.15, P < 0.05), stroke (χ² = 10.68, P < 0.05), arthritis or rheumatic disease (χ² = 7.13, P < 0.05), osteoporosis (χ² = 39.51, P < 0.05), and memory-related diseases (χ² = 7.00, P < 0.05) were higher among female advanced schistosomiasis patients than among male cases, and the comorbidity rate of malignant tumors was higher among male cases than among female cases (10.26% vs. 7.41%; χ² = 4.13, P = 0.042). The cluster dendrogram showed that advanced schistosomiasis patients' comorbid chronic diseases in Suzhou City were mainly divided into three clusters: (1) hypertension, chronic gastric diseases; (2) chronic pulmonary diseases, arthritis or rheumatic diseases, osteoporosis, chronic liver diseases, heart diseases, and stroke; and (3) diabetes, sleep disorders, gallbladder diseases, over-weight and obesity, atopic dermatitis, chronic kidney diseases, mental and psychological diseases, malignant tumors, asthma, and memory-related diseases. Conclusions There are multiple types of comorbid chronic diseases among advanced schistosomiasis patients in Suzhou City, with high prevalence, which necessitates the implementation of effective preventive measures and interventions targeting comorbid chronic diseases among advanced schistosomiasis patients.

This paper summarizes the clinical experience in treating children adenoid hypertrophy using the "opening the orifices and regulating qi method". It is considered that the pathogenesis of adenoid hypertrophy in children is rooted in dysfunction of zangfu （脏腑） organs， with binding of phlegm and stasis as the branch. Obstruction of the cervical passes and rebellious， chaotic qi flow run through the entire course of the disease. The "opening the orifices and regulating qi method" is proposed， which emphasizes the regulation of the lung， spleen， liver， and stomach. By opening the cervical passes， regulating zangfu organs， and eliminating phlegm and stasis to harmonize the ascent and descent of qi， a comprehensive application of external traditional Chinese medicine （TCM） therapies， such as acupuncture， umbilical moxibustion with medicinals， collateral bloodletting， and sole therapy， is utilized. Addressing both root and branch causes， this approach provides new perspectives for treating children adenoid hypertrophy using external TCM therapies.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth. Procedural decisions for the amount of pulp tissue removal or retention depend on the diagnostic of pulp vitality, the overall treatment plan, the patient's general health status, and pulp inflammation reassessment during operation. This statement represents the consensus of an expert committee convened by the Society of Cariology and Endodontics, Chinese Stomatological Association. It addresses the current evidence to support the application of pulpotomy as a potential alternative to root canal treatment (RCT) on mature permanent teeth with pulpitis from a biological basis, the development of capping biomaterial, and the diagnostic considerations to evidence-based medicine. This expert statement intends to provide a clinical protocol of pulpotomy, which facilitates practitioners in choosing the optimal procedure and increasing their confidence in this rapidly evolving field.
