BACKGROUND:Precision therapy based on multifunctional nanomaterials is a novel therapeutic model for malignancies that can integrate multiple imaging and therapeutic models into one nanoscale platform to achieve visual combination treatment. OBJECTIVE:To prepare novel nanoparticles loaded with Cu2(OH)PO4 nanoparticles(CuNPs)and nuciferine(NF)(h-PCuNF),and to explore their ability to mediate combined photothermal therapy/photodynamic therapy/chemodynamic therapy/chemotherapy for malignancy. METHODS:The h-PCuNF nanoparticles were synthesized through a double-emulsion procedure,through which the CuNPs and NF were loaded into the shell of hollow poly(lactic-co-glycolic)acid nanocarriers.The morphology,structure,particle size,and zeta potential of the h-PCuNF nanoparticles were characterized.In deionized water,the magnetic resonance imaging and photothermal conversion performances of the h-PCuNF nanoparticles,as well as their capability to implement reactive oxygen species production by mediating photocatalysis and Fenton-like reactions,were evaluated.In liver malignant tumor cell line HepG2 cells,the effectiveness of the photothermal therapy/photodynamic therapy/chemodynamic therapy/chemotherapy combination therapy mediated by the nanoparticles was detected by employing fluorescence imaging and MTT assay. RESULTS AND CONCLUSION:(1)The h-PCuNF nanoparticles possessed a hollow spherical structure in which the CuNPs(drug loading rate and encapsulation rate were 26.3%and 63.2%,respectively)and NF(drug loading rate and encapsulation rate were 11.0%and 52.6%,respectively)were loaded into the shell.The average particle size of the h-PCuNF nanoparticles was(309.2±10.0)nm,while the zeta potential was determined to be(-12.5±0.9)mV.In physiological environments,the nanoparticles possess favorable suspension stability.(2)In deionized water,the h-PCuNF nanoparticles could markedly enhance T1-weighted magnetic resonance imaging images.The h-PCuNF nanoparticles showed remarkable photothermal conversion and photocatalytic reactive oxygen species generation capabilities under near infrared laser irradiation.In addition,the h-PCuNF nanoparticles could consume glutathione and mediate Fenton-like reactions to produce·OH.(3)The h-PCuNF nanoparticles could be taken up by HepG2 tumor cells and were mainly distributed in the cytoplasm.The synergistic therapeutic effect was demonstrated after the nanoparticles were activated by near infrared laser irradiation,because CuNPs mediated photothermal therapy/photodynamic therapy/chemodynamic therapy and NF mediated chemotherapy could synergistically eliminate the tumor cells.

Pulmonary sarcoidosis is an immune system disease with an unclear etiology. Guided by the yang-reinforcing method, it is believed that the fundamental pathogenesis of pulmonary sarcoidosis lies in the disharmony between water and fire and the reckless movement of the ministerial fire. The failure of the spleen and stomach to maintain warmth, leading to the production of phlegm and blood stasis, is an important pathogenesis. The invasion of external pathogenic toxins, deeply penetrating into the interior, is considered a triggering factor for the disease. The treatment focuses on supplementing the yang, consolidating the kidney, drawing fire back to its source, warming the yang, benefiting the kidney, and nourishing the spleen to generate metal. It also emphasizes unblocking the yang, transforming turbidity, and eliminating phlegm and blood stasis.

With the rapid advancement of vaccines, the research and application of vaccine adjuvants have garnered significant attention. Despite the development of numerous vaccine adjuvants, their applications in human vaccines remain limited due to either insufficient efficacy or severe side effects. Consequently, there is growing interest in developing bioactive compounds derived from traditional Chinese medicines (TCMs) as vaccine adjuvants, owing to their natural biocompatibility, diversity, and safety. Here, we systematically review the current application status and potential value of TCM-based bioactive compounds in vaccine adjuvants. Firstly, we elaborate on the types and characteristics of active ingredients, such as polysaccharides, saponins, flavonoids, acids, and alkaloids. The mechanisms by which these compounds function as vaccine adjuvants are then discussed, including their roles in enhancing humoral immunity, cellular immunity, and relieving the immune suppression in the microenvironment. Additionally, we summarize the current strategies for structural modification and platform optimization to adapt to different application scenarios. Finally, we offer insights into the future development directions for these potential adjuvants, highlighting research priorities, technical approaches, and application prospects. In conclusion, natural vaccine adjuvants derived from TCMs present broad application prospects and hold promise for future vaccine development.

Liver transplantation (LT) has become a standard treatment for end-stage liver diseases, and graft injury is intricately associated with poor prognosis. Granzyme B (GZMB) plays a vital role in natural killer (NK) cell biology, but whether NK-derived GZMB affects graft injury remains elusive. Through the analysis of single-cell RNA-sequencing data obtained from human LT grafts and the isolation of lymphocytes from mouse livers following ischemia-reperfusion injury (IRI), we demonstrated that 2NK cells with high expression of GZMB are enriched in patients and mice. Both systemically and liver-targeted depletion of NK cells led to a notable reduction in GZMB+ cell infiltration, subsequently resulting in diminished graft injury. Notably, the reconstitution of Il2rg -/- Rag2 -/- mice with purified Gzmb-KO NK cells demonstrated superior outcomes compared to those with wild-type NK cells. Crucially, global knockout of GZMB and pharmacological inhibition exhibited remarkable improvements in liver function in both mouse IRI and rat LT models. Moreover, a phosphorylated derivative of FDA-approved vidarabine was identified as an effective inhibitor of mouse GZMB activity by molecular dynamics, which could provide a potential avenue for therapeutic intervention. Therefore, targeting NK cell-derived GZMB during the LT process suggests potential therapeutic strategies to improve post-transplant outcomes.

This article is based on ZHANG Jingyue's theory of yin-yang holism to explore the etiology, pathogenesis, and treatment of acute exacerbation of rheumatoid arthritis-associated interstitial lung disease (RA-ILD). It is believed that the foundation of acute exacerbation of RA-ILD lies in real yin insufficiency and yin fail to control yang; external pathogen attacking is a common cause of acute exacerbation of RA-ILD. For treatment, it is important to first suppress ministerial fire by prescribing modified Yinhuo Decoction (引火汤); if ministerial fire submerged, focus should be on nourishing both yin and yang; if real yin deficiency is the main issue, modified Zuogui Pill (左归丸) should be used; if real yang deficiency is prominent as well, modified Yougui Pill (右归丸) can be chosen. When yin and yang balanced, the disease could be solved.

Rapidly increasing intraocular pressure(IOP)is a typical manifestation of acute angle-closure glaucoma and an important cause of ocular tissue damage, vision loss and even blindness in glaucoma patients. The sharp increase of intraocular pressure in a short period of time in acute angle-closure glaucoma will cause characteristic damage to the structure and function of retina, choroid and optic nerve. Currently, the diagnosis and evaluation of the course of glaucoma is largely dependent on the state of high IOP, changes in the optic nerve and visual field damage, but irreversible damage to the fundus has already been made in glaucoma patients by this time. The microstructural changes in the posterior segment of the eye are more sensitive to high IOP and often appear before optic nerve and visual field damage, which can indicate the damage of high IOP to the eye earlier. Through the evaluation of the imaging characteristics of the posterior segment of the eye, the morphological characteristics that affect the prognosis of glaucoma can be explored, which is clinically important for the early diagnosis of glaucoma.

Retinopathy of prematurity(ROP), an abnormal vascular proliferative retinopathy of prematurity, is a serious condition that can lead to retinal detachment or blindness. With the development of neonatal medicine, the survival rate of low birth weight and low gestational age infants has been increasing, as well as the incidence of ROP. Therefore, studying ROP's pathogenesis and influencing factors is of great clinical importance. Numerous studies have been conducted on the risk factors for ROP, including gestational age, oxygen intake, mode of delivery, neonatal bronchopulmonary dysplasia, and the use of surfactants. At present, it is widely accepted both at home and abroad that preterm birth, low birth weight, and high oxygen concentration after birth are independent risk factors for ROP. In recent years, more and more scholars have found that abnormalities in blood indicators in preterm infants may be associated with the development of ROP. This article reviews the effects of platelets, haemoglobin, blood glucose, inflammatory cells, and lipids on ROP, providing a reference for identifying and preventing risk factors for ROP.

Refractory chronic cough belongs to the category of "refractory cough" in traditional Chinese medicine, and it is believed that the root cause of intractable chronic cough is wind lodging in the spleen collaterals, with poor spleen yang and deficient kidney essence as the pathologic basis of the disease, which is present throughout the disease. The method advocated is to search the spleen collaterals and eliminate latent wind, warm the spleen yang and smooth the middle jiao, cultivate the kidney essence and consolidate the root, prescribed with modified Fuzi Lizhong Decoction (附子理中汤) plus Erxian Decoction (二仙汤) as the basis. The Fuzi Lizhong Decoction can warm yang and fortify the middle, and smooth the middle jiao, and the Erxian Decoction can cultivate the kidney essence and consolidate the innate. The two prescriptions could combine with Suye (Perilla frutescens), Jingjie (Dysphania ambrosioides), Fangfeng (Carum carvi) and other medicinals of cleaning characteristic, or combine with Gouteng (Uncaria rhynchophylla), Chuanshanlong (Dioscorea nipponica), Dilong (Kummerowia striata) and other medicinals of worm or cane category, to find the wind and expel pathogen, smooth spleen collaterals.

Objective:To evaluate the consistency of the Chinese three-dimensional anterior visual field analysis system (Scansys), the anterior segment analyzer (Pentacam), the frequency-domain anterior segment optical coherence tomography system (CASIA SS-1000), and a new ultra-high frequency digital ultrasound scanning system (Arcscan Insight100) to measure central vault after implantable collamer lens (ICL) implantation in myopic eyes with crystalline lenses.Methods:A diagnostic test study was conducted.Fifty-six myopic patients (56 eyes) who underwent ICL V4c implantation from June to December 2019 were included.Scansys, Pentacam, CASIA and Arcscan were used to measure the central vault after surgery.The vault measurements were compared.Correlations between the measurements of the four instruments were analyzed using Pearson correlation analysis, and consistency comparisons were analyzed using the Bland-Altman method.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2021[13]). Written informed consent was obtained from each subject.Results:The central vault measurements by Scansys, Pentacam, CASIA and Arcscan were (481.8±191.6), (476.4±190.6), (619.3±207.5) and (534.0±221.2)μm, respectively, with a statistically significant overall difference ( F=143.301, P<0.001). The vault measurements by Scansys and Pentacam were significantly lower than CASIA and Arcscan, and Arcscan was lower than CASIA, with statistically significant differences (all at P<0.001). There were strong positive correlations in vault measurements between Arcscan and CASIA, Arcscan and Pentacam, Arcscan and Scansys, CASIA and Pentacam, CASIA and Scansys, Pentacam and Scansys ( r=0.982, 0.933, 0.931, 0.942, 0.941, 0.989; all at P<0.001). Intraclass correlation coefficients of vault measurements by Scansys, Pentacam, CASIA and Arcscan were 0.985, 0.975, 0.998, 0.992, respectively.The 95% limits of agreement of vault measurements differences were -170 to 0, 0 to 280, 0 to 280, -110 to 210, -100 to 220 μm, between CASIA and Arcscan, CASIA and Scansys, CASIA and Pentacam, Arcscan and Scansys, Arcscan and Pentacam, respectively, and the maximum absolute value of the difference was beyond the clinically acceptable range, showing poor agreement.The 95% limits of agreement of vault measurement difference was -60 to 50 μm between Scansys and Pentacam, showing a good agreement. Conclusions:The repeatability of the vault after ICL V4c implantation in myopic eyes measured by the four instruments is good.Among them, the vault measurements of Scansys and Pentacam are smaller, showing good consistency, and their results could be substituted for each other.The measurement of CASIA is the largest, followed by Arcscan, which have a large difference from each other, and their results can not be substituted for each other, which should be comprehensively analyzed with the actual situation in clinical work.
