ObjectiveTo establish an ultra-performance liquid fingerprint and multi-components determination method for Naomaili granules. To evaluate the quality of different batches by chemometrics, and the anti-neuroinflammatory effects of water extract and main components of Naomaili granules were tested in vitro. MethodsThe similarity and common peaks of 27 batches of Naomaili granules were evaluated by using Ultra performance liquid chromatography (UPLC) fingerprint detection. Ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) technology was used to determine the content of the index components in Naomaili granules and to evaluate the quality of different batches of Naomaili granules by chemometrics. LPS-induced BV-2 cell inflammation model was used to investigate the anti-neuroinflammatory effects of the water extract and main components of Naomaili granules. ResultsThe similarity of fingerprints of 27 batches of samples was > 0.90. A total of 32 common peaks were calibrated, and 23 of them were identified and assigned. In 27 batches of Naomaili granules, the mass fractions of 14 components that were stachydrine hydrochloride, leonurine hydrochloride, calycosin-7-O-glucoside, calycosin,tanshinoneⅠ, cryptotanshinone, tanshinoneⅡA, ginsenoside Rb1, notoginsenoside R1, ginsenoside Rg1, paeoniflorin, albiflorin, lactiflorin, and salvianolic acid B were found to be 2.902-3.498, 0.233-0.343, 0.111-0.301, 0.07-0.152, 0.136-0.228, 0.195-0.390, 0.324-0.482, 1.056-1.435, 0.271-0.397, 1.318-1.649, 3.038-4.059, 2.263-3.455, 0.152-0.232, 2.931-3.991 mg∙g-1, respectively. Multivariate statistical analysis showed that paeoniflorin, ginsenoside Rg1, ginsenoside Rb1 and staphylline hydrochloride were quality difference markers to control the stability of the preparation. The results of bioactive experiment showed that the water extract of Naomaili granules and the eight main components with high content in the prescription had a dose-dependent inhibitory effect on the release of NO in the cell supernatant. Among them, salvianolic acid B and ginsenoside Rb1 had strong anti-inflammatory activity, with IC50 values of (36.11±0.15) mg∙L-1 and (27.24±0.54) mg∙L-1, respectively. ConclusionThe quality evaluation method of Naomaili granules established in this study was accurate and reproducible. Four quality difference markers were screened out, and eight key pharmacodynamic substances of Naomaili granules against neuroinflammation were screened out by in vitro cell experiments.

ObjectiveTo evaluate the effect of Ningying Formula (宁瘿方) combined with low-dose antithyroid drugs (ATDs) on the relapse risk for patients with Graves' hyperthyroidism (GH) during the remission phase, and to analyze the related factors between GH relapse and thyrotropin receptor antibody (TRAb) negativity, so as to provide evidence for the standardized management of GH in remission stage. MethodsA single-center retrospective cohort study was conducted, including 269 GH patients in the remission stage. After propensity score matching (PSM), 102 matched pairs (204 patients) were established. The control group received low-dose ATDs as maintenance therapy, while the exposure group received the core Ningying Formula in addition to low-dose ATDs. The primary outcome was the GH recurrence rate; the secondary outcome was the thyrotropin receptor antibody (TRAb) negativity rate (TRAb<1.75 IU/L). Safety outcomes included treatment-related adverse events. Differences between groups were assessed using Cox regression models and Kaplan-Meier curves, with sensitivity analysis performed using inverse probability of treatment weighting (IPTW). ResultsThe median follow-up in the matched cohort was 28.07 months. Regarding the GH recurrence outcome, the recurrence rate in the exposure group (18/102, 17.6%) was significantly lower than that in the control group (31/102, 30.4%; χ²=4.539, P=0.033); regarding the TRAb negativity outcome, the TRAb negativity rate in the exposure group (50/102, 49.0%) was significantly higher than that in the control group (23/102, 22.5%; χ²=15.551, P<0.001). Multivariate Cox regression analysis for recurrence showed that Ningying Formula treatment reduced the risk of recurrence [HR=0.324, 95%CI(0.170, 0.617), P<0.001]. Male [HR=2.209, 95%CI(1.079, 4.520), P=0.030], higher initial TRAb level [per 1 IU/L increase: HR=1.033, 95%CI(1.003, 1.064), P=0.032], and larger thyroid volume [per 1 ml increase: HR=1.045, 95%CI(1.003, 1.088), P=0.035] were identified as independent risk factors for recurrence; multivariate Cox regression analysis for TRAb negativity indicated that Ningying Formula treatment promoted TRAb negativity [HR=1.826, 95%CI(1.091, 3.056), P=0.022], while a higher initial TRAb level was associated with a lower probability of negativity [HR=0.974, 95%CI(0.950, 0.998), P=0.032]. Survival analysis showed significant differences in relapse rate between groups (Log-Rank P=0.003) and in TRAb outcomes (Log-Rank P=0.034). The incidence of treatment-related adverse events was similar between groups (P=0.757). The IPTW sensitivity analysis was consistent with the primary analysis, indicating robust results. ConclusionThe Ningying Formula combined with low-dose ATDs can significantly reduce the risk of recurrence and can improve the TRAb negativity rate in GH patients during the remission stage, without increasing common adverse events, making it an optional strategy for reducing relapse risk during remission. Male gender, higher baseline TRAb level, and larger thyroid volume indicate a higher risk of recurrence, warranting focused follow-up and stratified management.

OBJECTIVE To investigate the mechanism of pachymic acid on renal injury in pregnancy induced hypertension (PIH) rats by regulating the silent information regulator transcript 1/peroxisome proliferator-activated receptor γ coactivator-1α (Sirt1/PGC-1α) pathway. METHODS Pregnant SD rats were prepared by co-caging and PIH model was induced using N-nitro-L- arginine methyl ester (L-NAME) method. PIH rats were randomly divided into model group, L-pachymic acid (low-dose pachymic acid, 10 mg/kg) group, H-pachymic acid (high-dose pachymic acid, 20 mg/kg) group, and H-pachymic acid+EX527 (20 mg/kg pachymic acid+10 mg/kg EX527) group, with 6 rats in each group. Another 6 normal pregnant rats were selected as blank group. Each group was given relevant medicine or solvent intragastrically or intraperitoneally daily, once a day, for 28 consecutive days. After the last administration, 24 h urinary protein and tail artery systolic blood pressure (SBP) were measured in pregnant rats from each group, along with the levels of serum creatinine (Scr), blood urea nitrogen (BUN),uric acid (UA), and cystatin C (Cys-C). The contents of superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), and 8-hydroxy-2′-deoxyguanosine (8-OHdG) in renal tissue, as well as the mRNA and protein expression levels of Sirt1 and PGC-1α, were also determined. Meanwhile, renal histopathological changes in rats from each group were evaluated using hematoxylin-eosin (HE) staining and periodic acid-Schiff (PAS) staining. RESULTS Compared with model group, L-pachymic acid group and H-pachymic acid group exhibited significant decreases in 24 h urine protein quantification, tail artery SBP, Scr, BUN, UA, Cys-C levels, glomerulosclerosis index score of renal tissue, renal tubular injury score, the percentage of PAS positive area, MDA and 8-OHdG (P<0.05). Conversely, the contents of SOD and GSH-Px, along with the mRNA and protein expression levels of Sirt1 and PGC-1α, were significantly increased (P<0.05). Moreover, these improvements were more pronounced in H-pachymic acid group (P<0.05). Compared with H-pachymic acid group, the aforementioned indicators in pregnant rats from the H-pachymic acid+EX527 group showed significant reversal (P<0.05). CONCLUSIONS Pachymic acid significantly ameliorates renal injury induced by PIH in rats, potentially through activation of the Sirt1/PGC-1α pathway.

OBJECTIVE To evaluate the efficacy and safety of total glucosides of paeonia (TGP) in the treatment of systemic lupus erythematosus (SLE). METHODS Randomized controlled trial (RCT) about TGP combined with western medicine versus western medicine alone for SLE treatment were retrieved from PubMed, Embase, Cochrane Library, Web of Science, CNKI, VIP, Wanfang Data, and CBM. The search period spanned from the inception of each database to June 1, 2025. After literature screening, data extraction, and quality assessment of the included studies, Meta-analysis was performed using RevMan 5.4 software. RESULTS Fifteen RCTs, involving 1 318 patients, were included. Meta-analysis results showed that compared with western medicine alone, TGP combined with western medicine significantly improved clinical efficacy [OR=4.96, 95%CI(3.41, 7.23), P<0.000 01], complement 3 [MD=0.18, 95%CI (0.13, 0.23), P<0.000 01] and complement 4[MD=0.08, 般021) 95%CI (0.04, 0.11), P<0.000 01], and reduced the levels of immunoglobulin G (IgG) [MD=-3.10, 95%CI (-3.59,-2.62), P<0.000 01], IgA [MD=-0.68, 95%CI (-0.78, -0.58), P<0.000 01], IgM [MD=-0.43, 95%CI (-0.53,-0.34), P<0.000 01], systemic lupus erythematosus disease activity index (SLEDAI) [MD=-1.59, 95%CI (-2.20, -0.99), P<0.000 01], recurrence rate [OR=0.23, 95%CI (0.13, 0.42), P<0.000 01] and the incidence of adverse drug reactions [OR= 0.54, 95%CI (0.36, 0.82), P=0.004]. CONCLUSIONS TGP therapy can improve clinical efficacy of SLE patients, promote the restoration of immunoglobulins and complements, reduce SLEDAI and recurrence rate and has good safety.

Oral squamous cell carcinoma (OSCC) is a common head and neck malignancy. Approximately 50% to 60% of patients with OSCC are diagnosed at a locally advanced stage (clinical staging III-IVa). Even with comprehensive and sequential treatment primarily based on surgery, the 5-year overall survival rate remains below 50%, and patients often suffer from postoperative functional impairments such as difficulties with speaking and swallowing. Programmed death receptor-1 (PD-1) inhibitors are increasingly used in the neoadjuvant treatment of locally advanced OSCC and have shown encouraging efficacy. However, clinical practice still faces key challenges, including the definition of indications, optimization of combination regimens, and standards for efficacy evaluation. Based on the latest research advances worldwide and the clinical experience of the expert group, this expert consensus systematically evaluates the application of PD-1 inhibitors in the neoadjuvant treatment of locally advanced OSCC, covering combination strategies, treatment cycles and surgical timing, efficacy assessment, use of biomarkers, management of special populations and immune related adverse events, principles for immunotherapy rechallenge, and function preservation strategies. After multiple rounds of panel discussion and through anonymous voting using the Delphi method, the following consensus statements have been formulated: 1) Neoadjuvant therapy with PD-1 inhibitors can be used preoperatively in patients with locally advanced OSCC. The preferred regimen is a PD-1 inhibitor combined with platinum based chemotherapy, administered for 2-3 cycles. 2) During the efficacy evaluation of neoadjuvant therapy, radiographic assessment should follow the dual criteria of Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and immune RECIST (iRECIST). After surgery, systematic pathological evaluation of both the primary lesion and regional lymph nodes is required. For combination chemotherapy regimens, PD-L1 expression and combined positive score need not be used as mandatory inclusion or exclusion criteria. 3) For special populations such as the elderly (≥ 70 years), individuals with stable HIV viral load, and carriers of chronic HBV/HCV, PD-1 inhibitors may be used cautiously under the guidance of a multidisciplinary team (MDT), with close monitoring for adverse events. 4) For patients with a poor response to neoadjuvant therapy, continuation of the original treatment regimen is not recommended; the subsequent treatment plan should be adjusted promptly after MDT assessment. Organ transplant recipients and patients with active autoimmune diseases are not recommended to receive neoadjuvant PD-1 inhibitor therapy due to the high risk of immune related activation. Rechallenge is generally not advised for patients who have experienced high risk immune related adverse events such as immune mediated myocarditis, neurotoxicity, or pneumonitis. 5) For patients with a good pathological response, individualized de escalation surgery and function preservation strategies can be explored. This consensus aims to promote the standardized, safe, and precise application of neoadjuvant PD-1 inhibitor strategies in the management of locally advanced OSCC patients.

ObjectiveTo investigate the mechanism of modified Si Junzitang and Shashen Maidong Tang [Yiqi Yangyin Jiedu prescription (YQYYJD)] in enhancing the sensitivity of cisplatin in epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI)-resistant lung adenocarcinoma cells based on aerobic glycolysis. MethodsThe effects of different concentrations of YQYYJD (0, 2, 3, 4, 5, 6, 7, 8 g·L-1) and cisplatin (0, 3, 6, 9, 12, 15, 18, 21, 24, 27 mg·L-1) on the proliferation and activity of PC9/GR cells were detected by the cell counting kit-8 (CCK-8) assay after 24 hours of intervention. The half-maximal inhibitory concentration (IC50) for PC9/GR cells was calculated to determine the concentrations used in subsequent experiments. PC9/GR cells were divided into blank group (complete medium), YQYYJD group (5 g·L-1), cisplatin group (12 mg·L-1), and combined group (YQYYJD 5 g·L-1 + cisplatin 12 mg·L-1). After 24 hours of intervention, cell viability was measured using CCK-8 assay. Cell proliferation was assessed by colony formation assay, and cell migration was evaluated by scratch and Transwell assays. Glucose consumption, lactate production, and adenosine triphosphate (ATP) levels were measured by colorimetric assays. The expression levels of glycolysis-related proteins, including hexokinase 2 (HK2), phosphofructokinase P (PFKP), pyruvate kinase M2 (PKM2), lactate dehydrogenase A (LDHA), glucose transporter 1 (GLUT1), and monocarboxylate transporter 4 (MCT4), were determined by Western blot. ResultsBoth YQYYJD and cisplatin inhibited the viability of PC9/GR cells in a concentration-dependent manner. The IC50 of PC9/GR cells for YQYYJD and cisplatin were 5.15 g·L-1 and 12.91 mg·L-1, respectively. In terms of cell proliferation, compared with the blank group, the cell survival rate and the number of colonies formed in the YQYYJD group, cisplatin group, and combined group were significantly decreased (P<0.01). Compared with the YQYYJD and cisplatin groups, the combined group showed a further significant reduction in cell survival rate and colony formation (P<0.01). In terms of cell migration, compared with the blank group, the cell migration rate and the number of cells passing through the Transwell membrane in the YQYYJD group, cisplatin group, and combined group were significantly decreased (P<0.01). Compared with the YQYYJD and cisplatin groups, the combined group exhibited a further significant reduction in cell migration rate and the number of cells passing through the Transwell membrane (P<0.01). In terms of glycolysis, compared with the blank group, glucose consumption, lactate production, and ATP levels in the YQYYJD group, cisplatin group, and combined group were significantly decreased (P<0.01). Compared with the YQYYJD and cisplatin groups, the combined group showed a further significant reduction in glucose consumption, lactate production, and ATP levels (P<0.05). Compared with the blank group, the protein expression levels of HK2, PFKP, PKM2, and LDHA in the YQYYJD, cisplatin, and combined groups were significantly decreased (P<0.01). The combined group showed a further significant reduction in the expression levels of these proteins compared with the YQYYJD and cisplatin groups (P<0.01). No significant differences were observed in the protein expression levels of GLUT1 and MCT4 among the groups. ConclusionYQYYJD can synergistically inhibit the proliferation and migration of PC9/GR cells and enhance their sensitivity to cisplatin. The mechanism may be related to the downregulation of the expression of glycolysis-related rate-limiting enzymes, including HK2, PFKP, PKM2, and LDHA, thereby inhibiting glycolysis.

ObjectiveTo observe the prognosis effect of soluble programmed death ligand-1(sPD-L1) in treating patients with advanced lung adenocarcinoma treated with epidermal growth factor receptor-tyrosine kinase inhibitors(EGFR-TKIs) and the influence of Yiqi Yangyin Jiedu prescription. MethodA prospective cohort-controlled study was conducted to enroll patients treated with EGFR-TKIs in the first line of treatment,who were admitted to the Oncology Department of Longhua Hospital and Shanghai Chest Hospital from May 1st, 2021 to June 30th, 2023, and they were evaluated as non-progressive and identified with deficiency of Qi and Yin after one month of treatment. The patients were divided into an exposed group (EGFR-TKIs combined with Yiqi Yangyin Jiedu prescription) and a non-exposed group (EGFR-TKIs alone)according to whether or not they were treated with Yiqi Yangyin Jiedu prescription and were treated until disease progression, or death and intolerable adverse reactions occurred. The enzyme-linked immunosorbent assay (ELISA) was applied to detect the level of sPD-L1 in patients at the time of enrollment and disease progression,and Cox risk proportionality model was used to analyze the independent prognostic factors affecting disease progression of patients treated with EGFR-TKIs. ResultA total of 90 patients (39 in the exposed group and 51 in the non-exposed group) undergoing disease progression after EGFR-TKI treatment were enrolled. At the time of enrolment and after disease progression,the levels of serum sPD-L1 in the 90 patients were 12.06 (27.54) ng·L-1 and 41.99 (62.93) ng·L-1,respectively. Compared with that at the time of enrollment, the serum sPD-L1 level in the 90 patients was significantly increased after disease progression (P<0.01). The serum sPD-L1 level in patients in the exposed group was 12.27 (24.78) ng·L-1 and 29.57 (61.12)ng·L-1 respectively at the time of enrolment and after disease progression. In the non-exposed group, patients had serum sPD-L1 levels of 11.81 (28.46) ng·L-1 and 49.54 (74.12) ng·L-1 respectively at the time of enrolment and after disease progression. Compared with that at the time of enrollment, the serum sPD-L1 level in the two groups of patients was significantly increased after disease progression (P<0.01). In addition, compared with that in the non-exposed group, the sPD-L1 level in the exposed group was greatly reduced after disease progression(P<0.01). Cox multifactorial analysis showed that sPD-L1 level and age at the time of enrolment were associated with patients' progression-free survival(PFS),and that low levels of sPD-L1 (<12.06 ng·L-1) prolonged the PFS and reduced the risk of disease progression in patients treated with EGFR-TKIs compared with high levels of sPD-L1. ConclusionElevated sPD-L1 level is a poor prognostic factor for the long-term efficacy of EGFR-TKIs,and treatment with Yiqi Yangiin Jiedu prescription can down-regulate sPD-L1 level of patients treated with EGFR-TKIs.

ObjectiveTo establish a model that can quickly identify the aroma components in different parts of Nardostachys jatamansi, so as to provide a quality control basis for the market circulation and clinical use of N. jatamansi. MethodsHeadspace solid-phase microextraction-gas chromatography-mass spectrometry(HS-SPME-GC-MS) combined with Smart aroma database and National Institute of Standards and Technology(NIST) database were used to characterize the aroma components in different parts of N. jatamansi, and the aroma components were quantified according to relative response factor(RRF) and three internal standards, and the markers of aroma differences in different parts of N. jatamansi were identified by orthogonal partial least squares-discriminant analysis(OPLS-DA) and cluster thermal analysis based on variable importance in the projection(VIP) value >1 and P<0.01. The odor data of different parts of N. jatamansi were collected by Heracles Ⅱ Neo ultra-fast gas phase electronic nose, and the correlation between compound types of aroma components collected by the ultra-fast gas phase electronic nose and the detection results of HS-SPME-GC-MS was investigated by drawing odor fingerprints and odor response radargrams. Chromatographic peak information with distinguishing ability≥0.700 and peak area≥200 was selected as sensor data, and the rapid identification model of different parts of N. jatamansi was established by principal component analysis(PCA), discriminant factor alysis(DFA), soft independent modeling of class analogies(SIMCA) and statistical quality control analysis(SQCA). ResultsThe HS-SPME-GC-MS results showed that there were 28 common components in the underground and aboveground parts of N. jatamansi, of which 22 could be quantified and 12 significantly different components were screened out. Among these 12 components, the contents of five components(ethyl isovalerate, 2-pentylfuran, benzyl alcohol, nonanal and glacial acetic acid,) in the aboveground part of N. jatamansi were significantly higher than those in the underground part(P<0.01), the contents of β-ionone, patchouli alcohol, α-caryophyllene, linalyl butyrate, valencene, 1,8-cineole and p-cymene in the underground part of N. jatamansi were significantly higher than those in the aboveground part(P<0.01). Heracles Ⅱ Neo electronic nose results showed that the PCA discrimination index of the underground and aboveground parts of N. jatamansi was 82, and the contribution rates of the principal component factors were 99.94% and 99.89% when 2 and 3 principal components were extracted, respectively. The contribution rate of the discriminant factor 1 of the DFA model constructed on the basis of PCA was 100%, the validation score of the SIMCA model for discrimination of the two parts was 99, and SQCA could clearly distinguish different parts of N. jatamansi. ConclusionHS-SPME-GC-MS can clarify the differential markers of underground and aboveground parts of N. jatamansi. The four analytical models provided by Heracles Ⅱ Neo electronic nose(PCA, DFA, SIMCA and SQCA) can realize the rapid identification of different parts of N. jatamansi. Combining the two results, it is speculated that terpenes and carboxylic acids may be the main factors contributing to the difference in aroma between the underground and aboveground parts of N. jatamansi.

ObjectiveBased on ultra performance liquid chromatography-quadrupole-electrostatic field orbital trap high-resolution mass spectrometry(UPLC-Q-Orbitrap-MS), to identify the in vivo and in vitro chemical components of total phenolic acids in Gei Herba(TPAGH), and to clarify the pharmacological effects and potential mechanisms of the effective part in promoting acute wound healing and inhibiting scar formation. MethodsUPLC-Q-Orbitrap-MS was used to identify the chemical components of TPAGH and ingredients absorbed in vivo after topical administration. A total of 120 ICR mice were randomly divided into the model group, recombinant human epidermal growth factor(rhEGF) group(4 mg·kg-1), and low, medium, and high dose groups of TPAGH(3.5, 7, 14 mg·kg-1), with 24 mice in each group. A full-thickness skin excision model was constructed, and each administration group was coated with the drug at the wound site, and the model group was treated with an equal volume of normal saline, the treatment was continued for 30 days, during which 8 mice from each group were sacrificed on days 6, 12, and 30. The healing of the wounds in the mice was observed, and histopathological changes in the skin tissues were dynamically observed by hematoxylin-eosin(HE), Masson, and Sirius red staining, and enzyme-linked immunosorbent assay(ELISA) was used to dynamically measure the contents of interleukin-6(IL-6), tumor necrosis factor-α(TNF-α), vascular endothelial growth factor A(VEGFA), matrix metalloproteinase(MMP)-3 and MMP-9 in skin tissues. Network pharmacology was used to predict the targets related to the promotion of acute wound healing and the inhibition of scar formation by TPAGH, and molecular docking of key components and targets was performed. Gene Ontology(GO) biological process analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were carried out for the related targets, so as to construct a network diagram of herbal material-compound-target-pathway-pharmacological effect-disease for further exploring its potential mechanisms. ResultsA total of 146 compounds were identified in TPAGH, including 28 phenylpropanoids, 31 tannins, 23 triterpenes, 49 flavonoids, and 15 others, and 16 prototype components were found in the serum of mice. Pharmacodynamic results showed that, compared with the model group, the TPAGH groups showed a significant increase in relative wound healing rate and relative scar inhibition rate(P<0.05), and the number of new capillaries, number of fibroblasts, number of new skin appendages, epidermal regeneration rate, collagen deposition ratio, and Ⅲ/Ⅰ collagen ratio in the tissue were significantly improved(P<0.05, 0.01), the levels of IL-6, TNF-α, MMP-3 and MMP-9 in the skin tissues were reduced to different degrees, while the level of VEGFA was increased. Network pharmacology analysis screened 10 core targets, including tumor protein 53(TP53), sarcoma receptor coactivator(SRC), protein kinase B(Akt)1, signal transducer and activator of transcription 3(STAT3), epidermal growth factor receptor(EGFR) and so on, participating in 75 signaling pathways such as advanced glycation end-products(AGE)-receptor for AGE(AGE/RAGE) signaling pathway, phosphatidylinositol 3-kinase(PI3K)/Akt signaling pathway, mitogen-activated protein kinase(MAPK) signaling pathway. Molecular docking confirmed that the key components genistein, geraniin, and casuariin had good binding ability to TP53, SRC, Akt1, STAT3 and EGFR. ConclusionThis study comprehensively reflects the chemical composition of TPAGH and the absorbed components after topical administration through UPLC-Q-Orbitrap-MS. TPAGH significantly regulates key indicators of skin healing and tissue reconstruction, thereby clarifying its role in promoting acute wound healing and inhibiting scar formation. By combining in vitro and in vivo component identification with network pharmacology, the study explores how key components may bind to targets such as TP53, Akt1 and EGFR, exerting therapeutic effects through related pathways such as immune inflammation and vascular regeneration.

[摘 要] 自2017年以来,已有12款嵌合抗原受体基因修饰T淋巴细胞(CAR-T细胞)产品相继被批准用于血液系统恶性肿瘤的治疗,包括复发性/难治性急性B淋巴细胞白血病、特定亚型B细胞淋巴瘤和多发性骨髓瘤。然而,CAR-T细胞疗法在应用过程中面临诸多挑战,如在治疗血液系统肿瘤中的抵抗、生产周期长、个体化/价格昂贵,在实体瘤中的肿瘤异质性强/抗原逃逸、浸润能力不足、免疫抑制微环境和反应性差等问题。随着肿瘤免疫学研究的深入和基因工程技术的发展,尝试了众多新策略来提升CAR-T细胞疗法的疗效和普适性。作者根据自身对该领域研究的认知,针对CAR-T细胞疗法的临床关键问题及其应对解决策略进行述评,为未来CAR-T细胞疗法的基础研究和临床转化提供重要思路。
