The complex anatomical structure and physiological barriers of the eye present substantial challenges for local drug delivery, leading to suboptimal ocular drug bioavailability, which typically remains below 5% in conventional ophthalmic formulations. Frequent or high-dose administration not only increases the treatment burden but also heightens the risk of both local and systemic adverse effects. Liposomes, as an advanced drug delivery system, enhance ocular bioavailability through their biocompatibility and targeted delivery properties. Recent innovations in surface modification and functionalization have further enhanced their ability to overcome ocular barriers and facilitate controlled drug release. Liposome-based formulations have demonstrated significant therapeutic potential for diseases such as glaucoma and dry eye syndrome. Drawing on the research advancements over the past 5 a, this article systematically reviews the innovative design strategies and applications of liposomes in ocular drug delivery, with the aim of providing theoretical basis and technical reference for the development of new ophthalmic drugs.

Based on the theory of "three regions and sanjiao" in traditional Chinese medicine (TCM), the acupuncture-moxibustion differentiation and treatment system is explored and constructed for spasm syndrome, so as to provide a clearer guiding framework for TCM treatment of spasm syndrome. This disorder is caused essentially by the invasion of pathogenic wind, and located in brain marrow. The key regions of illness cover five zang organs and five tissues, and the core pathogenesis is associated with wind disturbance in brain marrow. In differentiation, spasm syndrome refers to overall transmission (from the upper to the lower) and local transmission (from exterior to interior). This disorder can be classified into sanjiao spasm (heart-lung spasm of the upper jiao, liver-spleen spasm of the middle jiao, and liver-kidney spasm of the lower jiao) and three-region spasm (skin-vessel spasm of the upper region, tendon-muscle spasm of the middle region, and tendon-bone spasm of the lower region). Based on "three regions and sanjiao" theory of acupuncture and moxibustion, 7 "expelling-wind" points can be selected in terms of the etiology of this disease. Baihui (GV20)-toward-Taiyang (EX-HN5) needling is applied to regulate the brain marrow, focusing on the core location of illness; and regarding the key location of illness, the combination of back-shu and front-mu points and that of jing-well and xing-spring points are adopted to regulate five zang organs. The five needling techniques (half needling, leopard-spot needling, joint needling, Hegu needling and shu needling) are used to regulate five tissues.

Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C0), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug-drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

Numerous c-mesenchymal-epithelial transition (c-MET) inhibitors have been reported as potential anticancer agents. However, most fail to enter clinical trials owing to poor efficacy or drug resistance. To date, the scaffold-based chemical space of small-molecule c-MET inhibitors has not been analyzed. In this study, we constructed the largest c-MET dataset, which included 2,278 molecules with different structures, by inhibiting the half maximal inhibitory concentration (IC50) of kinase activity. No significant differences in drug-like properties were observed between active molecules (1,228) and inactive molecules (1,050), including chemical space coverage, physicochemical properties, and absorption, distribution, metabolism, excretion, and toxicity (ADMET) profiles. The higher chemical diversity of the active molecules was downscaled using t-distributed stochastic neighbor embedding (t-SNE) high-dimensional data. Further clustering and chemical space networks (CSNs) analyses revealed commonly used scaffolds for c-MET inhibitors, such as M5, M7, and M8. Activity cliffs and structural alerts were used to reveal "dead ends" and "safe bets" for c-MET, as well as dominant structural fragments consisting of pyridazinones, triazoles, and pyrazines. Finally, the decision tree model precisely indicated the key structural features required to constitute active c-MET inhibitor molecules, including at least three aromatic heterocycles, five aromatic nitrogen atoms, and eight nitrogen-oxygen atoms. Overall, our analyses revealed potential structure-activity relationship (SAR) patterns for c-MET inhibitors, which can inform the screening of new compounds and guide future optimization efforts.

Objective:To observe the clinical efficacy of exercise-based acupuncture in treating ischemic stroke and its effects in improving the patient's motor function and daily living ability. Methods:A total of 106 patients with motor dysfunction due to cerebral infarction were randomized into a trial group and a control group,each consisting of 53 cases.Both groups received conventional rehabilitation;in addition,the control group was given point-toward-point acupuncture at scalp points,and the trial group was offered exercise-based acupuncture,3 times weekly for 4 consecutive weeks.Before treatment,after 2 and 4 weeks of treatment,and at the 2-month follow-up,the Fugl-Meyer assessment(FMA)scale,Lovett scale for muscle strength,modified Ashworth scale(MAS),and activities of daily living(ADL)scale were used to assess the patient's motor function,muscle strength,muscle tension,and daily living ability. Results:After treatment,both groups gained improvements in motor function and daily living ability;after 4-week treatment and at the 2-month follow-up,the trial group had higher FMA and ADL scores than the control group(P<0.05).The MAS score decreased after treatment in both groups;after 2 and 4 weeks of treatment and at the 2-month follow-up,the MAS score was lower in the trial group than in the control group(P<0.05).After the intervention,the Lovett score increased in both groups;after 4 weeks of treatment,the Lovett score was higher in the trial group than in the control group(P<0.05). Conclusion:Based on routine rehabilitation,exercise-based acupuncture and scalp point-toward-point acupuncture both can improve the motor function and daily living ability in ischemic stroke patients;exercise-based acupuncture performs better than scalp point-toward-point acupuncture.

Mantle cell lymphoma (MCL) is a distinct histological type of B-cell lymphoma with a poor prognosis. Several agents, such as proteasome inhibitors, immunomodulatory drugs, and inhibitors of B cell lymphoma-2 and Bruton's tyrosine kinase have shown efficacy for relapsed or refractory (r/r) MCL but often have short-term responses. Chimeric antigen receptor (CAR) T-cell therapy has emerged as a novel treatment modality for r/r non-Hodgkin's lymphoma. However, long-term safety and tolerability associated with CAR T-cell therapy are not defined well, especially in MCL. In this report, we described a 70-year-old patient with r/r MCL with 48-month duration of follow-up who achieved long-term remission after CAR T-cell therapy. CAR T-cell-related toxicities were also mild and tolerated well even in this elderly patient. This report suggested that CAR T-cell therapy is a promising treatment modality for patients with MCL, who are generally elderly and have comorbid conditions.

Objective To evaluate the curative effect of the Duhuo-Jisheng decoction in treating knee osteoarthritis (KOA) with the deficiency of liver and kidney. Methods Using the random number table method, a total of 80 KOA patients were randomly divided into 2 group, 40 in each group. The treatment group were treated with Duhuo-Jisheng decoction, and the control group with glucosamine sulfate orally. The 2 groups were treated with 30 day. The blood sedimentation (ESR) of before and after treatment was detected. The level of C-reactive protein (CRP) was detected by latex enhanced immunization. The degree of knee joint pain was evaluated by VAS scale. The severity of the symptoms was evaluated by the visual scale of Osteoarthritis Index (Western Ontario Mac Master University Osteoarthritis index, WOMAC index). The changes of TCM symptoms were observed and the clinical effective rate was evaluated. Results The total effective rate of the treatment group was 95% (38/40), while the control group was 77.5% (31/40). The difference between the 2 groups was statistically significant (χ2=10.213, P=0.003). After treatment, the ESR (15.41 ± 4.23 mm/h vs. 17.6 ± 7.27 mm/h, t=-4.426), CRP (4.73 ± 1.28 mg/L vs. 6.12 ± 2.38 mg/L, t=-14.735) level in the treatemnt group were significantly lower than those in the control group (P<0.01). The VAS scores (2.5 ± 0.62 vs. 4.9 ± 0.8, t=-15.026), WOMAC index(12.1 ± 4.7 vs. 16.7 ± 6.7, t=-11.177) and TCM symptom score (6.5 ± 0.4 vs. 7.5 ± 0.4, t=-3.482) in the treatment group were significantly lower than those in the control group (P<0.01). Conclusions The Duhuo-Jisheng decoction is effective improve the symptom and quality of life of liver-kidney deficiency of KOA.
