Hepatocellular carcinoma (HCC) develops within a profoundly immunosuppressive tumor immune microenvironment (TIME), which limits the efficacy of immunotherapy. Polarization of tumor-associated macrophages (TAMs) toward a pro-tumorigenic M2 phenotype is a major driver of immune escape. Ferroptosis, an iron-dependent regulated cell death program, intersects with hepatic iron metabolism and immune regulation and thus offers promising points of therapeutic intervention. This review systematically elucidates the mechanistic role of TAM ferroptosis in HCC immune evasion and highlights a “bidirectional regulation” intervention strategy grounded in the Traditional Chinese medicine (TCM) principle of “fortifying healthy qi and eliminating pathogens” (Fuzheng Quxie). This strategy employs “eliminating pathogens” (Quxie) approaches to exploit the metabolic vulnerability of M2-like TAMs and precisely induce their ferroptosis. Moreover, it utilizes “fortifying healthy qi” (Fuzheng) approaches to protect M1-like TAMs and CD8⁺ T cells from oxidative damage. This parallel “induction-protection” paradigm demonstrates the unique advantages of TCM in systemically remodeling TIME through multitarget synergistic actions. Accordingly, precision regulation of TAM ferroptosis based on the Fuzheng Quxie theory represents a promising integrative Chinese-Western medicine strategy for overcoming current bottlenecks in HCC immunotherapy, although its clinical translational potential warrants further validation.

Objective:To investigate the correlation between imaging features of mixed ground-glass nodules(mGGNs)under dual lung enhanced CT and pathological subtypes of lung adenocarcinoma.Methods:Retrospective analysis of clinical data of 102 isolated mGGN lung adenocarcinoma patients admitted to Dalian Central Hospital from October 2016 to October 2018.The patients were divided into adenocarcinoma in situ(AIS)group,minimally invasive adenocarcinoma(MIA)group and invasive adenocarcinoma(IAC)group according to postoperative pathological examination results.Measure the maximum diameter lesions,the maximum diameter of solid components and the proportion of solid components to evaluate imaging features of three groups.The relationship between pathological subtypes of lung adenocarcinoma and baseline features,imaging features,mGGN lesions,maximum diameter of solid components and proportion of solid components were analyzed.The diagnostic value of the maximum diameter of lesions,the maximum diameter of solid components,and the proportion of solid components in IAC were analyzed by receiver operating characteristic(ROC)curves.Results:102 patients were divided into AIS group(n=20),MIA group(n=29)and IAC group(n=53)based on postoperative pathological diagnosis.There was a statistically significant difference in age among the three groups(P＜0.05).Tumor distribution locations:35 cases in the upper lobe of the right lung,10 cases in the middle lobe of the right lung,and 15 cases in the lower lobe of the right lung;23 cases in the upper lobe of the left lung and 19 cases in the lower lobe of the left lung,the tumor distribution locations in the upper lobe of the right lung was relatively high in various pathological subtypes.The lesions in AIS and MIA groups were mostly circular or elliptical in shape,whiile the lesions in the IAC group was mostly irregular in shape.There was a statistically significant difference in morphological comparisons among the three groups(P＜0.05).There was a statistically significant difference in burr sign between MIA group and IAC group(P＜0.05).There was a statistically significant difference in pleural indentation sign and bronchial inflation sign between MIA group and IAC group(P＜0.05).There was a statistically significant difference in the maximum diameter of lesions and the maximum diameter of solid components among the three groups(P＜0.05).The proportion of solid components in IAC group was higher than that in AIS and MIA groups,and the difference was statistically significant(P＜0.05).The ROC curve shows that,the area under curve(AUC)for diagnosing IAC based on the maximum diameter of the lesion,the maximum diameter of the solid component,and the proportion of the solid component were 0.840,0.966 and 0.816,respectively.The AUC of diagnosing IAC with the maximum diameter of the solid component was greater than the AUC of the maximum diameter of the lesion and the proportion of solid components(P＜0.05).Conclusion:Dual lung enhanced CT can evaluate the imaging features of mGGN,and it can distinguish the pathological subtypes of lung adenocarcinoma,when the maximum diameter of the lesion is ≥ 16.5 mm,the maximum diameter of the solid component is ≥5.5 mm,or the proportion of solid component is ≥47.00％,it can effectively diagnose IAC,the maximum diameter of solid components has the best diagnostic efficiency for IAC.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Reninoma is a rare renal secretory tumor，prevalent in the young population. This disease is mostly surgically resected，and the use of microwave ablation to treat reninoma in children is scarce. A case of reninoma in a child was reported in this paper. The patient presented with refractory hypertension，hypokalemia，hyperreninemia and hyperaldosteronemia. Enhanced CT and contrast-enhanced ultrasound showed mass in the lower pole of the right kidney，which was considered as reninoma and microwave ablation was performed. The renin concentration decreased to 68.42 pg/ml at 4 hours after surgery. After 1 year of postoperative follow-up，there was no recurrence of hypertension and hypokalemia，and no signs of tumor recurrence were seen on repeated ultrasound examinations.

Objective To investigate the role of CCCTC-binding factor(CTCF)in the development of oxaliplatin(OXA)-induced gastric cancer drug-tolerant cells(DTCs)and to preliminarily elucidate its underlying mechanisms.Methods The DTCs model of gastric cancer was established by treating MGC803 cells with OXA.Overexpression and knockdown of CTCF in MGC803 cells were performed to observe their effects on the formation of DTCs in gastric cancer.Additionally,Bcl2-like protein 1(BCL2L1)was knocked down in CTCF-overexpressing cells,and its impact on DTCs formation was evaluated.Flow cytometry was used to analyze the effects of varying CTCF/BCL2L1 expression levels on the apoptosis of gastric cancer cells under OXA treatment.Immunohistochemistry(IHC)was employed to detect the expression levels of CTCF/BCL2L1 in gastric cancer tissues,and the therapeutic outcomes of neoadjuvant chemotherapy in patients with different CTCF/BCL2L1 expression levels were assessed.Results Gastric cancer DTCs can be obtained following a regimen of continuous treatment of MGC803 cells with a specific concentration of oxaliplatin(OXA,1.5 μmol/L)for 5 days,followed by an additional 5-day culture period post-treatment cessation.The upregulation of CTCF has been shown to facilitate the formation of DTCs in gastric cancer,whereas its downregulation inhibits this process(P<0.05).In MGC803 gastric cancer cells,the expression level of BCL2L1 is positively correlated with that of CTCF.Knockdown of BCL2L1 in MGC803 cells overexpressing CTCF can reverse the pro-DTC formation effect of CTCF(P<0.05).Overexpression of CTCF confers resistance to OXA-induced apoptosis in gastric cancer cells,and this anti-apoptotic effect can be reversed by BCL2L1 knockdown in MGC803 cells overexpressing CTCF(P<0.05).In the tumor tissues of the majority of gastric cancer patients,the expression levels of BCL2L1 are positively correlated with those of CTCF,and the efficacy of neoadjuvant chemotherapy is notably reduced in patients with high expression of the CTCF/BCL2L1 axis compared to those with low expression(P<0.05).Conclusion CTCF promotes the formation of OXA-related gas-tric cancer DTCs by upregulating BCL2L1 expression and inhibiting apoptosis,making the CTCF/BCL2L1 axis a potential therapeutic target for DTCs in gastric cancer.

Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.

OBJECTIVE: To examine the effectiveness of Chinese medicine (CM) Lianhua Qingwen Granule (LHQW) and Jingyin Gubiao Prescription (JYGB) in asymptomatic or mild patients with Omicron infection in the shelter hospital. METHODS: This single-center retrospective cohort study was conducted in the largest shelter hospital in Shanghai, China, from April 10, 2022 to May 30, 2022. A total of 56,244 asymptomatic and mild Omicron cases were included and divided into 4 groups, i.e., non-administration group (23,702 cases), LHQW group (11,576 cases), JYGB group (12,112 cases), and dual combination of LHQW and JYGB group (8,854 cases). The length of stay (LOS) in the hospital was used to assess the effectiveness of LHQW and JYGB treatment on Omicron infection. RESULTS: Patients aged 41-60 years, with nadir threshold cycle (C_T) value of N gene <25, or those fully vaccinated preferred to receive CM therapy. Before or after propensity score matching (PSM), the multiple linear regression showed that LHQW and JYGB treatment were independent influence factors of LOS (both P<0.001). After PSM, there were significant differences in LOS between the LHQW/JYGB combination and the other groups (P<0.01). The results of factorial design ANOVA proved that the LHQW/JYGB combination therapy synergistically shortened LOS (P=0.032). CONCLUSIONS Patients with a nadir C_T value <25 were more likely to accept CM. The LHQW/JYGB combination therapy could shorten the LOS of Omicron-infected individuals in an isolated environment.

Moringa oleifera, widely utilized in Ayurvedic medicine, is recognized for its leaves, seeds, and velamen possessing traditional effects such as vātahara(wind alleviation), sirovirecaka(brain clearing), and hridya(mental nourishment). This study aims to identify the medicinal part of ■ in the Sārasvata ghee formulation as described in the Bower Manuscript, while investigating the ameliorative effects of different medicinal parts of M. oleifera on learning and memory deficits in mice and elucidating the underlying molecular mechanisms. A total of 144 male ICR mice were randomly assigned to the following groups: control, model(scopolamine hydrobromide, Sco, 2 mg·kg~(-1)), donepezil(donepezil hydrochloride, Don, 3 mg·kg~(-1)), M. oleifera leaf low-, medium-, and high-dose groups(0.5, 1, 2 g·kg~(-1)), M. oleifera seeds low-, medium-, and high-dose groups(0.25, 0.5, 1 g·kg~(-1)), and M. oleifera velamen low-, medium-, and high-dose groups(0.31, 0.62, 1.24 g·kg~(-1)). Learning and memory abilities were assessed using the passive avoidance test and Morris water maze. Nissl and HE staining were employed to examine histopathological changes in the hippocampus. Transcriptomics and targeted metabolomics were used to screen differential genes and metabolites, with MetaboAnalyst 6.0 and O2PLS methods applied to identify key disease-related targets and pathways. RESULTS:: demonstrated that M. oleifera leaf(1 g·kg~(-1)) significantly ameliorated Sco-induced learning and memory deficits, outperforming M. oleifera seeds(0.25 g·kg~(-1)) and M. oleifera velamen(1.24 g·kg~(-1)). This was evidenced by improved behavioral performance, reversal of neuronal damage, and reduced acetylcholinesterase(AChE) activity. Multi-omics analysis revealed that M. oleifera leaf upregulated Tuba1c gene expression through the synaptic vesicle cycle, enhancing glutamate(Glu), dopamine(DA), and acetylcholine(ACh) release via Tuba1c-Glu associations for neuroprotection. M. oleifera seeds targeted the dopaminergic synapse pathway, promoting memory consolidation through Drd2-ACh associations. M. oleifera velamen was associated with the cocaine addiction pathway, modulating dopamine metabolism via Adora2a-DOPAC, with limited relevance to learning and memory. In conclusion, M. oleifera leaf exhibits superior efficacy and mechanistic advantages over M. oleifera seeds and velamen, suggesting that the ■ in the Sārasvata ghee formulation is likely M. oleifera leaf, providing scientific evidence for its identification in ancient texts.
