Aromatic Chinese medicinal essential oils are volatile oils extracted from aromatic Chinese herbs, which can prevent and treat respiratory infectious diseases through multiple synergistic mechanisms including pathogen inhibition, immune regulation, and inflammatory response regulation. Essential oils are primarily used externally on the body to prevent infections and alleviate symptoms through methods like inhalation, smearing, topical application, bathing, gargling or as a suppository. They can also be utilized in the environment for disinfection and air purification, through methods like diffusion, vaporization, or spraying. The external application of essential oils extracted from Chinese aromatic herbs has the advantages of convenience, quick absorption, and simultaneous influence on both the body and mind. However, there are still challenges and deficiencies in aspects such as the positioning of functions, indications, safety, and the research on the mechanism of action. It has been proposed to combine the theory of aromatic Chinese medicinals with the characteristics of essential oils, and formulate prescriptions of Chinese medicinal essential oils under the principles of traditional Chinese medicine syndrome differentiation, and prevent and treat respiratory infectious diseases efficiently, accurately, and safely, thereby expanding the clinical application of aromatic Chinese medicinals and the preventive theory of traditional Chinese medicine.

International Eye Science 2025;25(4):620-626
Pathologic myopia is a leading cause of visual impairment worldwide. Its characteristic clinical manifestations include posterior staphyloma caused by pathological elongation of the axial length, myopic maculopathy and high myopia-associated optic neuropathy. Extensive research conducted both domestically and internationally has consistently demonstrated that genetics plays a significant role in the occurrence and progression of pathologic myopia. With the innovative development of genetics, it has become possible to predict, prevent, control, and treat pathologic myopia at the gene level. This paper reviews the characteristic clinical manifestations of pathologic myopia and its related genes to provide a basis for the etiology of pathologic myopia and potential targets for therapeutic intervention, to provide a reference for treating pathologic myopia and its complications at the genetic level, and to explore new and effective ways to control the development of pathologic myopia.

Volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) are common organic compounds in indoor and outdoor air, and enter the human body primarily through the respiratory tract and directly damage the respiratory system. Previous studies have suggested that exposure to VOCs/SVOCs may associate with the prevalence, incidence, and progression of asthma, but the extent of the associations is still vague. Furthermore, biomarkers for efficient and simple asthma diagnosis, typing, and attack prediction remain unclear at this stage. From the perspective of the collection and detection methods of VOCs/SVOCs, this paper summarized the epidemiological associations and underlying biological mechanisms between VOCs/SVOCs exposure and the prevalence, incidence, and progression of asthma in children/adults. It also demonstrated the application of VOCs/SVOCs in recent years in assisting asthma diagnosis, such as distinguishing asthma patients from the healthy population, differentiating different asthma phenotypes, and predicting asthma acute exacerbations, aiming to provide a scientific basis for improving current asthma management.

This paper summarizes clinical experience in treating acne based on the staged therapeutic principles of "eruption in warm diseases". It is considered that acne results from wind-heat retained in the lungs, invading the ying level and obstructing the blood collaterals, and is primarily a disorder involving both the wei and ying systems. In clinical practice, the treatment emphasizes the use of acrid-cool and sweet-cold methods. The core prescription is namely Yinqiaosan Qu Douchi Jia Xishengdi Danpi Daqingye Bei Xuanshen Fang (from Epidemic Warm Diseases [《温病条辨》]), and is adjusted according to the stage of disease. In the non-inflammatory stage, when the pathogen initially attacks the wei level, treatment focuses on acrid-cool herbs to release the exterior, with supplementary bitter-sweet ingredients such as Yejuhua (Chrysanthemum Indicum). In the inflammatory stage, with pronounced heat toxin in the qi level affecting the ying and blood, and local stagnation of qi and blood, the approach is to clear heat and resolve toxin, using blood-cooling and stasis-resolving herbs early to prevent progression. Herbs such as Pugongying (Taraxacum Mongolicum), Zihuadiding (Viola Yedoensis), Tiankuizi (Semiaquilegia Adoxoides), Chonglou (Paris Polyphylla), Machixian (Portulaca Oleracea), Zaojiaoci (Gleditsia Sinensis), Chuanshanjia (Manis Pentadactyla) may be added. In the post-inflammatory erythema stage, when yin of the ying level is depleted and internal deficiency-heat arises, sweet-cold herbs are recommended to nourish the stomach and generate fluids, with the possible addition of Yiwei Decoction (益胃汤).

ObjectiveJunctophilin-2 (JPH2) is an essential structural protein that maintains junctional membrane complexes (JMCs) in cardiomyocytes by tethering the plasma membrane to the sarcoplasmic reticulum, thereby facilitating excitation-contraction (E-C) coupling. Mutations in JPH2 have been associated with hypertrophic cardiomyopathy (HCM), but the molecular mechanisms governing its membrane-binding properties and the functional relevance of its membrane occupation and recognition nexus (MORN) repeat motifs remain incompletely understood. This study aimed to elucidate the structural basis of JPH2 membrane association and its implications for HCM pathogenesis. MethodsA recombinant N-terminal fragment of mouse JPH2 (residues1-440), encompassing the MORN repeats and an adjacent helical region, was purified under near-physiological buffer conditions.X-ray crystallography was employed to determine the structure of the JPH2 MORN-Helix domain. Sequence conservation analysis across species and junctophilin isoforms was performed to assess the evolutionary conservation of key structural features. Functional membrane-binding assays were conducted using liposome co-sedimentation and cell-based localization studies in COS7 and HeLa cells. In addition, site-directed mutagenesis targeting positively charged residues and known HCM-associated mutations, including R347C, was used to evaluate their effects on membrane interaction and subcellular localization. ResultsThe crystal structure of the mouse JPH2 MORN-Helix domain was resolved at 2.6 Å, revealing a compact, elongated architecture consisting of multiple tandem MORN motifs arranged in a curved configuration, forming a continuous hydrophobic core stabilized by alternating aromatic residues. A C-terminal α-helix further reinforced structural integrity. Conservation analysis identified the inner groove of the MORN array as a highly conserved surface, suggesting its role as a protein-binding interface. A flexible linker segment enriched in positively charged residues, located adjacent to the MORN motifs, was found to mediate direct electrostatic interactions with negatively charged phospholipid membranes. Functional assays demonstrated that mutation of these basic residues impaired membrane association, while the HCM-linked R347C mutation completely abolished membrane localization in cellular assays, despite preserving the overall MORN-Helix fold in structural modeling. ConclusionThis study provides structural insight into the membrane-binding mechanism of the cardiomyocyte-specific protein JPH2, highlighting the dual roles of its MORN-Helix domain in membrane anchoring and protein interactions. The findings clarify the structural basis for membrane targeting via a positively charged linker and demonstrate that disruption of this interaction—such as that caused by the R347C mutation—likely contributes to HCM pathogenesis. These results not only enhance current understanding of JPH2 function in cardiac E-C coupling but also offer a structural framework for future investigations into the assembly and regulation of JMCs in both physiological and disease contexts.

The majority of attendees were aged 25-<35 years, accounting for 92 445 cases (36.99%). Among them, 785 cases were confirmed as HIV positive, with a positivity rate of 0.31%. Multivariable logistic regression analysis revealed that males (OR=4.787, 95%CI: 3.562-6.434), 45-<65 years of age (45-<55 years, OR=7.723, 95%CI: 1.786-33.406; 55-<65 years, OR=7.689, 95%CI: 1.757-33.653), being unmarried (OR=2.143, 95%CI: 1.580-2.906), junior high school education or below (OR=1.147, 95%CI: 1.042-2.430), having the history of high-risk behaviors or exposure risks (commercial heterosexual behaviors, OR=2.717, 95%CI: 1.707-4.324; non-commercial non-fixed heterosexual behaviors, OR=5.421, 95%CI: 3.763-7.809; homosexual behaviors, OR=70.774, 95%CI: 48.409-103.473; having an HIV-positive spouse/fixed partner/mother, OR=100.024, 95%CI: 62.490-160.100; drug injection, OR=5.366, 95%CI: 2.213-13.014), and seeking general hospitals or traditional Chinese medicine hospitals (OR=1.973, 95%CI: 1.650-2.360) were associated with a higher risk of HIV confirmed positive.
Conclusions
HIV confirmed positive among individuals attending VCT clinics in Inner Mongolia Autonomous Region is associated with gender, age, marital status, educational level, reasons for consultation, and consulting institutions. It is recommended to strengthen health education and targeted interventions for high-risk populations to reduce the risk of HIV infection.

ObjectiveBy observing the effect of Qianyang Yuyin granules on the phenotype of renal tubule epithelial cells, the intervention of Qianyang Yuyin granule on renal interstitial fibrosis was investigated. MethodThe renal tubular epithelial cells (HK-2) were treated with different concentrations of transforming growth factor (TGF)-β1 (5, 10, 15, 20, 25 μg·L-1) for 24 hours, and cell morphology and growth state were observed with an inverted phase contrast microscope. The 20 μg·L-1 was selected as the most appropriate concentration of TGF-β1 according to Western blot results for subsequent experiments. HK-2 cells were divided into six groups: blank group, TGF-β1 group (concentration of 20 μg·L-1), low, medium, and high dose Qianyang Yuyin granule groups (concentration of 0.5, 1, 2 g·L-1), and valsartan group (1 × 10-5 mol·L-1). The cell activity was measured by cell proliferation and cell counting kit-8 (CCK-8). The cell migration ability was detected by scratch test. The Transwell method was used to detect the invasiveness of cells. Western blot was used to detect levels of fibronectin (FN), E-cadherin, α-smooth muscle activator (α-SMA), Vimentin, collagen type Ⅰ(Col Ⅰ), collagen type Ⅳ(Col Ⅳ), and other related proteins. ResultTGF-β1 stimulating epithelial-mesenchymal transition (EMT) in renal tubular epithelial cells was time- and concentration-dependent. Compared with the blank group, higher concentration in the TGF-β1 group indicates longer intervention time and more obvious long spindle change of cells, and the migration and invasion ability of the cells was significantly enhanced. The protein expression level of FN, α-SMA, Vimentin, Col Ⅰ, and Col Ⅳ increased significantly (P<0.05, P<0.01), while the expression level of E-cadherin protein decreased (P<0.05). Compared with the TGF-β1 group, Qianyang Yuyin granule groups could maintain normal cell morphology, and the migration and invasion ability of the cells was inhibited. The protein expression level of FN, α-SMA, Vimentin, Col Ⅰ, and Col Ⅳ decreased (P<0.05, P<0.01), and the expression of E-cadherin protein was significantly restored (P<0.05). ConclusionQianyang Yuyin granule can reverse TGF-β1-induced interstitial transformation of renal tubular epithelial cells by reducing the phenotypic expression of mesenchymal cells and increasing the phenotypic expression of epithelial cells.

ObjectiveTo investigate the efficacy and safety of cinobufagin tablets combined with thalidomide/dexamethasone (TD) regimen in the treatment of newly diagnosed multiple myeloma (NDMM) with phlegm and stasis obstruction. MethodsThe clinical data of 50 patients with NDMM of phlegm and stasis obstruction who were hospitalized at the Jiangsu Province Hospital of Chinese Medicine from June 1st, 2015 to July 31th, 2019 were retrospectively analyzed, and they were divided into a control group (bortezomib/dexamethasone-containing regimen, 27 cases) and an observation group (cinobufagin tablets combined with TD regimen, 23 cases). The clinical efficacy and safety were compared between the two groups after two or three courses of treatment. The primary outcomes were clinical remission rate including overall response rate and deep remission rate, one-year and two-year overall survival rate, and adverse effects. The secondary outcomes were the proportion of plasma cells in bone marrow, hemoglobin, β2-microglobulin, lactate dehydrogenase, serum creatinine, blood urea nitrogen, bone pain score, and KPS functional status score (KPS score) before and after treatment. ResultsIn terms of clinical efficacy, there was no statistically significant difference (P>0.05) in the overall response rate [the observation group 69.57%(16/23) vs the control group 70.37% (19/27)] and deep remission rate [the observation group 56.52% (13/23) vs the control group 55.56% (15/27)] between groups after the treatment. The one-year overall survival rates of the observation group and the control group were 90.9% and 92.4%, and the two-year overall survival rates were 81.8% and 80.9% respectively, with no statistically significant differences between groups (P>0.05). During the treatment, no renal function injury occurred in both groups. The incidence of peripheral nerve injury in the observation group was 8.70%, which was lower than 48.15% in the control group (P<0.01). After the treatment, the proportion of myeloma plasma cells, β2-microglobulin, serum creatinine level, and bone pain score decreased, while the hemoglobin level and KPS score increased in both groups (P<0.05 or P<0.01). Compared between groups after treatment, the bone pain score of the observation group was lower than that of the control group, while the KPS score was higher than that of the control group (P<0.05). ConclusionThe clinical efficacy of cinobufagin tablets combined with TD in the treatment of NDMM is equivalent to bortezomib/dexamethasone-containing regimen, but the former is more helpful in relieving the pain and improving the quality of life, and has better safety.
