OBJECTIVE To investigate the effects and mechanism of modified Xiaoqinglong decoction combined with bone marrow mesenchymal stem cells (BMSCs) on nasal-pulmonary-intestinal mucosal immunity in rats with cold asthma. METHODS SD rats were randomly divided into blank group, model group, BMSCs group, BMSCs+modified Xiaoqinglong decoction (6.39 g/kg) group, and BMSCs+dexamethasone (0.125 mg/kg) group, with 10 rats in each group. The cold asthma rat model was established by sensitization and atomization challenge with ovalbumin combined with aluminum hydroxide, together with cold air stimulation from air conditioners. One hour before the initial atomization challenge, rats in all groups except the blank group and model group were injected with BMSCs suspension via the tail vein. Starting from the 15th day of the experiment, rats in each group were intragastrically administered corresponding liquid medicine or normal saline once a day for 7 consecutive days. After the last administration, the asthmatic behavioral changes and pathological morphological changes of lung tissues in rats were evaluated. The levels of interleukin-6 (IL-6) and IL-10 in nasopharyngeal lavage fluid, bronchoalveolar lavage fluid (BALF) and intestinal mucus were detected. The expression levels of proteins related to the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway in nasal, lung and intestinal tissues were determined. RESULTS Compared with the blank group, the asthmatic behavioral score, lung tissue injury score, IL-6 levels in nasopharyngeal lavage fluid, BALF and intestinal mucus, PI3K protein expression and Akt phosphorylation levels in nasal, lung and intestinal tissues of rats in the model group were significantly increased ( P <0.05); the IL-10 levels in nasopharyngeal lavage fluid, BALF and intestinal mucus were significantly decreased ( P <0.05). Alveolar atrophy, collapse and even fusion, abnormal hyperplasia and hypertrophy of bronchial smooth muscle, and massive inflammatory cell infiltration were observed. Compared with the model group, most of the above quantitative indicators in the BMSCs group, BMSCs+modified Xiaoqinglong decoction group and BMSCs+dexamethasone group were significantly reversed ( P <0.05), and pathological injuries of lung tissues were markedly alleviated. Compared with the BMSCs group, most of the above quantitative indicators were further improved in the BMSCs+modified Xiaoqinglong decoction group ( P <0.05). CONCLUSIONS Modified Xiaoqinglong decoction combined with BMSCs can effectively improve nasal-pulmonary-intestinal mucosal immunity and relieve asthmatic symptoms in cold asthma rats, and its mechanism may be related to inhibiting the activation of the PI3K/Akt signaling pathway.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Conventional chemotherapy based on cytotoxic drugs is facing tough challenges recently following the advances of monoclonal antibodies and molecularly targeted drugs. It is critical to inspire new potential to remodel the value of this classical therapeutic strategy. Here, we fabricate bisphosphonate coordination lipid nanogranules (BC-LNPs) and load paclitaxel (PTX) to boost the chemo- and immuno-therapeutic synergism of cytotoxic drugs. Alendronate in BC-LNPs@PTX, a bisphosphonate to block mevalonate metabolism, works as both the structure and drug constituent in nanogranules, where alendronate coordinated with calcium ions to form the particle core. The synergy of alendronate enhances the efficacy of paclitaxel, suppresses tumor metastasis, and alters the cytotoxic mechanism. Differing from the paclitaxel-induced apoptosis, the involvement of alendronate inhibits the mevalonate metabolism, changes the mitochondrial morphology, disturbs the redox homeostasis, and causes the accumulation of mitochondrial ROS and lethal lipid peroxides (LPO). These factors finally trigger the ferroptosis of tumor cells, an immunogenic cell death mode, which remodels the suppressive tumor immune microenvironment and synergizes with immunotherapy. Therefore, by switching paclitaxel-induced apoptosis to mevalonate metabolism-triggered ferroptosis, BC-LNPs@PTX provides new insight into the development of cytotoxic drugs and highlights the potential of metabolism regulation in cancer therapy.

Integrase inhibitors (INSTIs) are the newest class of antiretroviral drug which are available to people living with the human immunodeficiency virus (HIV). Since 2007, five types of INSTIs have been marketed: Raltegravir, Elvitegravir, Dolutegravir, Bictegravir and Cabotegravir, all of which were approved by the US Food and Drug Administration (FDA) for use in the initiation of antiretroviral therapy (ART) in treatment-na?ve individuals. Compared with other types of antiretroviral drugs, INSTIs have better efficacy and tolerability, so many countries around the world have listed INSTIs-containing regimens as the preferred regimen for HIV ART. In recent years, with the widespread use of INSTIs, some research data suggest that INSTIs may have some adverse effects (AEs), such as central nervous system symptoms, abnormal lipid metabolism, weight gain, abnormal liver and kidney function, etc. This review summarizes the current use of INSTIs in people living with the HIV, and highlights the clinical efficacy and their AEs among the five types of INSTIs in China.

Vaccines are among the most effec-tive measures for preventing infectious diseases and play a crucial role in controlling the spread of these diseases.Adjuvants,serving as auxiliary com-ponents in vaccines,are indispensable in the vac-cine development process.Ideal adjuvants not only enhance the immune response,enabling the body to achieve optimal protective immunity but also play important roles in reducing the dosage of im-munogens and lowering vaccine production costs.To meet the demands of novel vaccines,many new types of adjuvants have been developed.However,there is still a lack of adjuvants that are safe,effec-tive,easy to prepare,highly pure,and suitable for a variety of vaccines in clinical settings.This article categorizes adjuvants and summarizes their mecha-nisms of action and characteristics,focusing on tra-ditional aluminum salt adjuvants and more modern lipid-based and nucleic acid-based adjuvants.The summary is based on a computer search of data-bases including PubMed,Embase,The Cochrane Li-brary,CNKI(China National Knowledge Infrastruc-ture),VIP Database,and Wanfang Database,using English search keywords such as Adjuvants,Vac-cine,Vaccine Adjuvant,aluminum salts,MF59,AS03,Toll-like receptor agonist,etc.,and corre-sponding Chinese search terms.The aim is to pro-vide references for the development and applica-tion of adjuvants.
