OBJECTIVE To evaluate the therapeutic effects and safety of everolimus combined with letrozole and conventional chemotherapy for metastatic or recurrent endometrial carcinoma (EC). METHODS The clinical and follow-up data of 156 patients with metastatic or recurrent EC admitted to Nanyang Central Hospital from January 2020 to January 2024 were analyzed retrospectively. They were divided into a control group (77 cases) and an observation group (79 cases) according to different therapeutic regimens. The control group received paclitaxel+carboplatin/cisplatin regimen, and concurrently took Letrozole tablets at a dose of 2.5 mg orally once daily; the observation group took Everolimus tablets 10 mg orally, once a day, in addition to the treatment regimen given to the control group. Each treatment cycle lasted 21 days, and both groups of patients underwent continuous treatment for 6 to 8 cycles. The short-term efficacy indicators (objective response rate and disease control rate), the levels of serum tumor markers [carbohydrate antigen 125, human epididymis protein 4, vascular endothelial growth factor and matrix metalloproteinase-9] and medium- to long-term efficacy indicators [progression-free survival (PFS) and overall survival (OS)] were compared between the two groups. Additionally, the occurrence of toxic and side effects in both groups of patients was recorded. RESULTS The objective response rate (53.16%), disease control rate (89.87%), median PFS (6.47 months) and median OS (10.79 months) of the observation group were significantly higher or longer than those (22.08%, 68.83%, 4.63 months, 8.84 months) of the control group (P<0.05). Compared with before treatment, the levels of serum tumor markers in both groups decreased significantly after 6 cycles of treatment; the above indexes of the observation group were significantly lower than those of the control group (P<0.05). The proportion of patients with stomatitis in the observation group was significantly higher than that of the control group (P<0.05), and there was no statistically significant difference in the proportions of patients experiencing other toxic and side effects, such as leukopenia, between the two groups (P>0.05). CONCLUSIONS The everolimus combined with letrozole and conventional chemotherapy can effectively improve the short-term efficacy and prolong the survival period in patients with metastatic or recurrent EC, but attention should be paid to the occurrence of toxic and side effects, especially stomatitis.

Nasopharyngeal carcinoma (NPC) is a malignant tumor originating from the mucosal epithelium of the nasopharynx. In recent years, its incidence and mortality rates have shown a continuous upward trend, and there is still a lack of therapeutic regimens with both favorable efficacy and safety in clinical practice. Mitogen-activated protein kinase (MAPK) signaling pathway plays a key regulatory role in biological processes such as cell proliferation, differentiation, apoptosis and invasion. It is widely involved in the occurrence and progression of NPC, and serves as an important target in the research field of anti-NPC therapy. This article systematically elaborates on the mechanism of action of the MAPK signaling pathway in NPC, and reviews the research status regarding the anti-NPC effect of active components of traditional Chinese medicine (TCM) and TCM compound prescriptions by regulating this signaling pathway. The results show that TCM active components, including flavonoids (luteolin, maackiain, baicalein, etc.), alkaloids (picrasidine Ⅰ, tetrandrine, etc.), terpenoids (bakuchiol, cantharidic acid), as well as traditional Chinese medicine compound formulas (such as Biyan jiedu capsules and Yiqi jiedu formula) can exert effects including inducing autophagy and apoptosis of NPC cells, promoting pyroptosis, reversing drug resistance, blocking epithelial-mesenchymal transition, weakening cell stemness and arresting cell cycle progression by regulating the MAPK signaling pathway, thereby inhibiting the occurrence and development of NPC through multiple pathways.

OBJECTIVE To identify tortoiseshell glue and antler glue in Qichong zuogui granules, and determine the contents of 12 chemical components. METHODS Identification and content determination were performed by using liquid chromatography- tandem mass spectrometry (LC-MS/MS) method. The identification was performed on Hypersil GOLD column with a mobile phase consisted of acetonitrile-0.1% formic acid solution (gradient elution); the electrospray ion source was used to scan in the positive ion multi-reaction detection mode. The mass charge ratio (m/z) 631.3→546.4, 631.3→921.4 was the detection ion pair for tortoiseshell glue, and the m/z 765.4→554.0, 765.4→733.0 was the detection ion pair for antler glue. The determination method for 12 chemical components was as follows: Accucore C18 column, methanol-0.1% formic acid as mobile phase (gradient elution); scanning range of positive and negative ions was m/z 100→1 000 with the electric spray ion source and single ion detection scanning mode. RESULTS Average retention times of the molecular ion peaks for characteristic peptide segments of tortoiseshell glue and antler glue were 6.28 and 6.77 min, respectively; the linear relationship of 12 chemical components was good within their respective concentration ranges, such as astragaloside Ⅳ, calycosin-7-O-β-D-glucoside, calycosin, chlorogenic acid, ferulic acid, betaine, amygdalin, rutin, hydroxysafflor yellow A, hyperoside, loganin, cyasterone (r>0.999); RSDs for precision, stability (24 h) and reproducibility tests were all less than 5%. The average sample recovery rates ranged from 98.04% to 101.08%. The average contents of 12 components were 1.83, 25.73, 13.76,56.71, 23.80, 49.82, 807.49, 15.01, 317.02, 60.21, 202.71 and 17.70 μg/g, respectively. CONCLUSIONS In this study, tortoiseshell glue and antler glue in Qixiong zuogui granules are identified, and the contents of 12 chemical components therein are determined. This provides a reference for the quality control of this granule.

Journal of Sun Yat-sen University(Medical Sciences) 2025;46(1):41-49
Stroke is a common acute cerebrovascular disease. Post-stroke cognitive impairment (PSCI) is one of the most common complications of stroke, which seriously affects the quality of life and physical health of patients. As a cutting-edge medical therapy, stem cells transplantation has great potential in the treatment of PSCI by reducing inflammation, promoting axon regeneration and immune regulation, and has become the focus of current research. However, the relationship between stem cells transplantation and PSCI has not been systematically summarized. Therefore, this paper will briefly summarize the biological functions of different types of stem cells, systematically comb out and summarize the mechanisms of stem cells transplantation in PSCI regulation and its applications in PSCI treatment, providing a deeper understanding and strategy for clinical PSCI management.
5.Central Mechanisms of Post-stroke Cognitive Impairment: Advances Based on Electroencephalogram and Magnetic Resonance Imaging
Journal of Sun Yat-sen University(Medical Sciences) 2025;46(1):61-69
Approximately one-third of stroke patients experience post-stroke cognitive impairment (PSCI), which significantly impacts their quality of life and survival time. The clinical evaluations of PSCI mainly rely on subjective neurophysiological scales due to its complex pathogenesis and lack of reliable, objective diagnostic tools. However, electroencephalogram (EEG) and magnetic resonance imaging (MRI) could provide objective indicators for diagnosis of PSCI. Based on EEG, MRI and EEG-MRI fusion, this article reviews recent advances in the central mechanisms of PSCI, focusing on changes in brainwave spectrum, brain structure, brain network etc., in order to explore the clinical values of EEG and MRI in predicting and diagnosing PSCI, enhance the understanding of its pathogenesis and provide a basis for accurate clinical diagnosis.

Nonalcoholic fatty liver disease(NAFLD) is the most common chronic liver disease in the world. Because of its complex pathogenesis, high clinical prevalence and large population, it poses a great threat and challenge to public health in the world. Therefore, active intervention measures are needed. Currently, western medicine is effective in reducing weight, reducing liver fat content, improving glucose-lipid metabolism and insulin resistance. However, for patients with NAFLD-related fibrosis and cirrhosis, there is still a lack of sufficient histological evidence to support its benefits, and randomized controlled trials are still needed to clarify. Lifestyle intervention is an important cornerstone for the treatment of NAFLD, but there are many problems such as poor implementation and low compliance of patients, and the clinical efficacy is not ideal. Traditional Chinese medicine(TCM) has the significant advantages of multiple pathways and multiple targets. Berberine, the active ingredient of TCM, can interfere with the production of NAFLD from multiple pathways, including increasing energy consumption, weight loss, improving glucose-lipid metabolism, improving insulin resistance, anti-inflammatory, anti-oxidation, regulating intestinal flora, restoring bile acid homeostasis, anti-fibrosis and so on, which can play a positive role in the treatment of NAFLD. At the same time, it was found that the combination of BBR with Chinese and western medicines had significant advantages in promoting drug absorption, improving oral bioavailability, increasing the highest biological distribution in the liver, enhancing the overall therapeutic effect of NAFLD, and reducing adverse drug reactions, which could provide reference for clinical medication.

[Objective] To perform genetic analysis on samples with weak agglutination and mixed agglutination of ABO blood group antigens in neonates, and to investigate the molecular biological characteristics of ABO subtypes in neonates. [Methods] Serological identification of ABO blood group was performed by tube method and microcolumn gel method. The ABO exons 2-7 were amplified by PCR, and the amplified products were sequenced by Sanger sequencing method to determine the genotype. [Results] Among the ABO blood group serological results of 14 neonates, 8 cases showed weakened A antigen, and 6 cases showed weakened B antigen. Seven samples were identified with ABO subtype alleles, with genotypes as A102/B101+c.538C>T, Aw26/B102, A205/O02, A205/B101(2 cases), Aw26/O02, B(A)06/O01, B101/O01(3 cases), A102/O01(2 cases), A102/B101 and B101/O02. Additionally, three other family members were also found to carry B(A)06 allele in a pedigree investigation. [Conclusion] For samples showing weakened antigens in ABO blood type identification of neonates, it is necessary to consider the possibility of ABO subtype in addition to age factors, and genetic testing can be used to prevent missed detection of ABO subtypes in neonates.

OBJECTIVE To study the mechanism of Xinnao shutong capsule alleviating cerebral ischemia reperfusion injury (CIRI) in rats by regulating the ferroptosis pathway. METHODS SD rats were randomly divided into sham operation group, model group, Xinnao shutong low-dose, high-dose group (220, 440 mg/kg), Ginkgo biloba leaves extract group (positive control, 150 mg/kg). Each group of rats was orally administered with the corresponding medication/normal saline for 7 consecutive days. Transient occlusion of the middle cerebral artery was adopted to induce the CIRI model; the samples were taken 24 h after the operation; the cerebral infarction area of rats was detected, and the cerebral infarction rate was calculated. The pathological changes of brain tissues were observed, and the levels of lipid peroxide (LPO), malondialdehyde (MDA) and glutathione (GSH) in cerebral tissue were detected; mRNA and protein expressions of nuclear factor-erythroid 2-related factor 2 (Nrf2), heme oxygenase 1(HO-1) and glutathione peroxidase 4 (GPX4) were all detected in cerebral tissue of rats. RESULTS Compared with model group, the cerebral infarction rate, the content of total iron in cerebral tissue and serum level of LPO (except for Ginkgo biloba leaves extract group and Xinnao shutong low-dose group) were all decreased significantly in G. biloba leaves extract group and Xinnao shutong groups (P<0.05 or P<0.01); the serum level of GSH, the protein and mRNA expressions of Nrf2, HO-1 and GPX4 were all increased significantly (P<0.05 or P<0.01). The pathological damage to brain tissue was reduced, the number of nerve cells increased, the edema was alleviated, and the nuclear membrane was flattened. CONCLUSIONS Xinnao shutong capsule can inhibit ferroptosis and reduce CIRI, the mechanism of which may be associated with the activation of the Nrf2/HO-1/GPX4 signaling pathway.

The Huangdi Neijing proposes the " using bitter herbs to nourish or purge" theory to guide clinical prescription and formulation of herbal remedies based on the physiological characteristics and functions of the five zang viscera, along with the properties and flavors of medicinal herbs. This study explored diabetic kidney disease pathogenesis and treatment based on the " using bitter herbs to nourish or purge" theory. Kidney dryness is a key pathological factor in diabetic kidney disease, and the disharmony of kidney dryness is an essential aspect of its pathogenesis. Strengthening is the primary therapeutic principle, and kidney dryness is a persistent factor throughout the occurrence and progression of diabetic kidney disease. In the early stage, the pathogenesis involves heat-consuming qi and injuring yin, leading to kidney dryness. In the middle stage, the pathogenesis manifests as qi deficiency and blood stasis in the collaterals, resulting in turbidity owing to kidney dryness. In the late stage, the pathogenesis involves yin and yang deficiency, with kidney dryness and disharmony. This study proposes the staging-based treatment based on the " need for firmness" characteristic of the kidney. The aim is to provide new insights for clinical diagnosis and treatment in traditional Chinese medicine by rationally using pungent, bitter, and salty medicinal herbs to nourish and moisturize the kidney. This approach seeks to promote precise syndrome differentiation and personalized treatment for different stages of diabetic kidney disease, thereby enhancing clinical efficacy.
