Lung cancer is a leading cause of cancer-related morbidity and mortality worldwide. Coupled with the substantial workload, the clinical management of lung cancer is challenged by the critical need to efficiently and accurately process increasingly complex medical information. In recent years, large language models (LLMs) technology has undergone explosive development, demonstrating unique advantages in handling complex medical data by leveraging its powerful natural language processing capabilities, and its application value in the field of lung cancer diagnosis and treatment is continuously increasing. The paper systematically analyzes that the exceptional potential of LLMs in lung cancer auxiliary diagnosis, tumor feature extraction, automatic staging, progression/outcome analysis, treatment recommendations, medical documentation generation, and patient education. However, they face critical technical and ethical challenges including inconsistent performance in complex integrated decision-making (e.g., TNM staging, personalized treatment suggestions) and "black box" opacity issues, along with dilemmas such as training data biases, model hallucinations, data privacy concerns, and cross-lingual adaptation challenges ("data colonization"). Future directions should prioritize constructing high-quality multimodal corpora specific to lung cancer, developing interpretable and compliant specialized models, and achieving seamless integration with existing clinical workflows. Through dual drivers of technological innovation and ethical standardization, LLMs should be prudently advanced for holistic lung cancer management processes, ultimately promoting efficient, standardized, and personalized diagnosis and treatment practices.

ObjectiveTo explore the effects of Jingui Shenqiwan （JSW） and Liuwei Dihuangwan （LDW） on the reproductive ability and brain function of normal mice and compare the actions of the two medications. MethodsSeven groups of female and male mice were divided at a ratio of 2∶1. Except for the control group， the other six groups were as follows： a group of both males and females receiving JSW （3.0 g·kg^-1）， a group of both males and females receiving LDW （4.5 g·kg^-1）， a group of males receiving water and females receiving JSW， a group of males receiving water while females receiving LDW， a group of females receiving water while males receiving JSW， and a group of females receiving water while males receiving LDW. Each group was administered the drug for 14 days and then caged together at a 2∶1 （female∶male） ratio to detect the number of pregnant mice and calculate the pregnancy rate. Pregnant mice continued receiving the drug until they naturally gave birth， which was followed by the observation of newborn mice， calculation of their average number， and the measurement of the offspring's preference for sugar water and neonatal recognition index. At the end of the experiment， the weights of the thymus and spleen were measured to calculate the organ coefficients， and mRNA or protein expression was analyzed in the brain and testes or ovaries. A 1% sucrose solution was used to examine the euphoria of their brain reward systems， while novel object recognition test （NOR） was applied to assess their memory capabilities. mRNA expression was detected using real-time quantitative polymerase chain reaction （Real-time PCR） assay， and protein expression was analyzed with Western blot. ResultsCompared with the control group， oral administration of JSW to both male and female mice for 14 days significantly increased the pregnancy rate of female mice on day 2 after being caged together （P<0.05）， while LDW showed a trend but no statistical significance. Additionally， compared with the control group， JSW could upregulate the gene expression of gonadotropin-releasing hormone （GnRH） in the thalamus， as well as reproductive stem cell factor （SCF） and tyrosine kinase receptor （c-Kit） in the testes and reproductive stem cell marker mouse vasa homologue （MVH） in the ovaries， upregulate the expression of proteins influencing neuronal functional activity， such as brain-derived neurotrophic factor （BDNF）， in hippocampal neurons （P<0.05）， and enhance sucrose preference in male mice （P<0.05）. Compared with the control group， JSW significantly increased sucrose preference and novel object recognition index in offspring mice （P<0.05）， which was related to the upregulation of hippocampal dopamine D1 receptor （D1R） and N-methyl-D-aspartate receptor （Nmdar） gene expression. Compared with the control group， both JSW and LDW could upregulate the protein expression of glucocorticoid receptor （GR）， BDNF， and tyrosine kinase receptor B （TrkB） in the hippocampus of offspring mice （P<0.05）. ConclusionJSW significantly enhances the reproductive ability of normal mice， which is not only related to the release of gonadotropin but also associated with its regulation of brain function. Additionally， JSW has a certain regulatory effect on the brain function of the offspring mice.

Objective To assess the current status and outcomes of living donor liver transplantation (LDLT) in patients with unresectable colorectal cancer liver metastases (CRLM). Methods Two reviewers independently conducted a systematic search of Medline (via PubMed), the Cochrane Library, and ClinicalTrials.gov in accordance with preferred reporting items for systematic reviews guidelines. English-language publications reporting LDLT for unresectable CRLM were identified; study characteristics and recipient outcomes were extracted. Results Twelve studies were retrieved, six completed studies enrolling 55 patients and six ongoing trials. Selected patients appeared to derive benefit from LDLT. Reported overall survival was 100% at 1 year and 100%, 71.4% at 3 years. The 1-year progression-free survival was 85.7% and 75.1%, and 3-year progression-free survival was 68.6% and 53.7%. Conclusions Prospective data on LDLT for unresectable CRLM remain scarce. The approach is still investigational and warrants validation through prospective clinical trials.

Objective: To investigate the molecular mechanism of Syk in phagocytosis induced by CD36 antibodies. Methods: In vitro, two CD36 monoclonal antibodies, GZ1 (IgG2a) and GZ4 (IgG1), at different concentrations were co-incubated with platelets from CD36-positive blood donors, and the affinity of the antibodies for platelets was assessed using flow cytometry. CD36 positive platelets from donors were labeled with Red-SE. The GZ1 and GZ4 antibodies were added together with dye-labeled platelets to peripheral blood from blood donors for phagocytosis experiments. The expression of the Spleen Tyrosine Kinase (Syk), P-Syk, P38 MAPK and P-P38 were detected using Western blot(WB). In the in vitro phagocytosis inhibition assay, Fcγ receptor (FcγR) antibodies or Syk inhibitor (R406) were pre-incubated with monocytes prior to performing the phagocytosis experiment. In vivo experiments were performed using female C57BL/6J mice. R406 was administered via intraperitoneal injection, followed by tail vein infusion of GZ1 or GZ4 antibodies. Additionally, a treatment group was set up in which the antibodies were infused first, followed by administration of R406. Changes in platelet counts were analyzed using a blood routine analyzer, and antibody binding to platelets was detected by flow cytometry. Results: GZ1 had higher affinity for CD36positive platelets than GZ4. The phagocytosis rate induced by GZ1 was significantly higher than that of GZ4 [(42.12±2.25)% vs (16.25±6.45)%, P<0.001]. Moreover, GZ1-mediated platelet phagocytosis mainly depends on FcγRⅠ of monocytes, while GZ4-mediated platelet phagocytosis mainly relies on FcγRⅡ of monocytes. WB results showed that the GZ1 group significantly upregulated the expression of Syk and phosphorylated Syk (P-Syk), and induced phosphorylation of the downstream P38 MAPK signaling pathway. Pretreatment of monocytes with R406 inhibited the phagocytosis of antibodyopsonized platelets by monocytes. After injecting GZ1 or GZ4 antibodies into C57BL/6 female mice through the tail vein, GZ1 mAbs had a stronger binding rate to the platelets compared with GZ4 mAbs, leading to a significant decrease in platelet count. After pre-injecting R406 into mice, the platelet count reduction in both the GZ1 and GZ4 groups was alleviated, and the binding rate of antibodies to platelets was also significantly reduced. However, administration of R406 after antibody injection failed to prevent the decrease in platelet counts in mice. Conclusion: This study indicates that Syk plays an important role in the phagocytosis of anti-CD36 opsonized platelets by monocytes/macrophages and is closely associated with the activation of the P38 MAPK signaling pathway.

Background: Sex-based differences often influence the therapeutic efficacy and safety of medications. Semen Cuscutae is a traditional tonic botanical drug with sex-specific characteristics, traditionally indicated for conditions such as impotence (exclusive to males) and restless fetus (exclusive to pregnant females). However, most existing studies have focused on a single sex. Objective: To evaluate the sex-specific biological effects of Semen Cuscutae in rats and explore its molecular mechanisms, with the aim of uncovering its pharmacological characteristics through a multiomics approach. Methods: A traditional aqueous extract of Semen Cuscutae (SCA) was used as the experimental material. Forty adult Sprague-Dawley rats (equal numbers of males and females) were randomly divided into 4 groups: male control, male SCA treatment (240 mg/kg), female control, and female SCA treatment (240 mg/kg), with 10 rats in each group. The biological effects were comprehensively evaluated using a combination of open field test, biochemical analyses, proteomics, and gut microbiota profiling. Results: As a tonic botanical drug, SCA appeared to directly affect the mental and behavioral state of rats. It significantly altered the time spent by rats in the center area during the open field test, showing a sex-dependent reversal of behaviors. Proteomic analysis of brain tissue identified 624 differentially expressed proteins across the groups, with 10 key differentially expressed proteins related to sex differences, including fibroblast growth factor receptor 3, transcription elongation factor A protein-like 1, 40S ribosomal protein S25, neural cell adhesion molecule, and anion exchange protein 2 (SLC4A2). Enrichment analysis revealed that in male rats, SCA upregulated proteins involved in biological processes such as ribosome function and energy derivation, supporting protein synthesis and enhancing energy supply, showing an overall gain effect. In contrast, in female rats, SCA downregulated proteins associated with processes such as positive regulation of target of rapamycin (TOR) signaling and vesicle transport, suggesting suppression of neuronal signaling and material transport, indicative of a shift toward a more restrained physiological state. Furthermore, SCA reduced gut microbiota diversity in female rats but increased it in males, including the abundance of Akkermansia, which may serve as a crucial mediator. Conclusion: Overall, the biological effects of SCA differ significantly between male and female rats, with evidence suggesting greater health benefits in males. These findings help elucidate the scientific basis of its traditional applications and provide guidance for the precise application of SCA as a functional health food.

ObjectiveTo explore the association between metabolic score for visceral fat（METS-VF） and cardiometabolic multimorbidity（CMM） as well as cognitive function in the elderly population， revealing the role of METS-VF as an assessment tool in this population， and providing evidence and new perspectives for the early screening and intervention strategies of CMM and cognitive function. MethodsThis study is based on cross-sectional data from the Hubei memory and aging cohort study（HMACS）， which includes elderly individuals aged 60 and above. The METS-VF index was calculated and divided into quartiles（Q1-Q4）. CMM was assessed through a questionnaire， defining CMM as the coexistence of at least two of the following conditions： diabetes， heart disease， and stroke. Standardized cognitive tests were used to evaluate overall cognition， memory， language， executive function， and attention. Logistic and Linear regression analysis was performed to explore the association between METS-VF and the risk of CMM as well as cognitive function. A restricted cubic spline was used to test the dose-response relationship， and subgroup analysis was conducted to assess the variation of METS-VF in different populations. Additionally， multinomial unordered logistic regression was used to evaluate the performance of METS-VF in predicting CMM morbidity patterns. ResultsA total of 3 790 elderly participants aged 60 and above were included. After adjusting for confounding factors， compared with the lowest quartile（Q1）， the Q4 group of METS-VF was associated with a higher risk of CMM ［OR=3.00，95%CI （2.18， 4.16）］， and with lower scores in overall cognition ［b=-0.12， 95%CI （-0.21，-0.04）］， attention ［b=-0.14， 95%CI （-0.24，-0.05）］， and executive function ［b=-0.10， 95%CI （-0.20，-0.00）］. Dose-response analysis did not show a nonlinear relationship between METS-VF and either CMM or cognitive function （P for nonlinear > 0.05）. Subgroup analysis revealed that the male group with higher METS-VF had lower overall cognitive scores， while the female group showed lower executive function scores （P for interaction ＜ 0.05 for both）. Multinomial unordered logistic regression analysis indicated that the METS-VF index was associated with an increased risk of diabetes with coronary heart disease ［OR=2.62，95%CI （1.66， 4.15）］ or concomitant stroke ［OR=2.66，95%CI （1.73， 4.09）］， especially in the group with both diabetes and stroke and coronary heart disease， where the association between METS-VF and the risk was strongest. ConclusionsAn increased METS-VF is associated with a higher risk of CMM and lower scores in overall cognition， attention， and executive function in the elderly population. Diabetes may be a key driving factor in the multimorbidity model. The METS-VF index can serve as a dual-purpose tool for screening cardiovascular metabolic risks and assessing cognitive function.

Objective To exploring the effect of inflammatory indicators on the outcome of assisted conception of in vitro fertilization/intracytoplasmic sperm injection(IVF/ICSI)in patients with ovarian endometriosis(OEM).Methods The study subjects were selected as the patients with OEM who received IVF/ICSI treatment at the Third Affiliated Hospital of Zhengzhou University from January 2019 to February 2024.Based on whether previous surgery for uterine endometriosis cyst removal had been performed,they were divided into non-surgery group(n=73)and surgery group(n=112).To explore the differences in inflammatory markers between two groups and to determine whether they have an impact on the outcome of assisted reproduction.Results The lymphocytes(L)and blastocyst formation rates of patients in surgery group were significantly higher than those in non-surgery group,platelet to lymphocyte ratio(PLR)and carbohydrate antigen 125(CA125)were significantly lower than those in non-surgery group(P＜0.05).There were no statistically significant differences in the clinical pregnancy rate and live birth rate between two groups of patients(P＞0.05).After adjusting for confounding factors,the results of multivariate Logistic regression analysis showed that L,PLR,and CA125 had no statistically significant impact on the clinical pregnancy rate and live birth rate(P＞0.05).Both maternal age and the number of embryos transferred exerted a certain influence on clinical pregnancy rates and live birth rates(P＜0.05),furthermore,the type of embryo transferred had a significant effect on clinical pregnancy rates(P＜0.05).Conclusion Compared with non-surgery group,surgery group had higher L level and lower PRL and CA125 levels,but these changes did not significantly affect clinical pregnancy or live birth outcomes in OEM patients undergoing IVF/ICSI assisted reproduction.

Objective:To evaluate the clinical efficacy of percutaneous balloon pulmonary valvuloplasty (PBPV) via antegrade venous-arterial loop in neonates with critical pulmonary stenosis with intact ventricular septum (CPS-IVS).Methods:A retrospective case review was conducted. Fifteen neonates with CPS-IVS who underwent PBPV via antegrade venous-arterial loop at the Women and Children′s Hospital, Qingdao University between September 2020 and September 2023 were included. Pre-and post-operative right ventricular functional parameters, surgical complications, and follow-up outcomes were analyzed. Paired-sample t-test was used to compare changes in right ventricular systolic pressure (RVSP), percutaneous oxygen saturation (SpO 2), and echocardiographic findings pre-and post-operatively, as well as during the follow-up period. Results:Among the 15 neonates (9 males and 6 females) with CPS-IVS, the surgical age was (3.6±0.5) d. All neonates underwent successful PBPV via antegrade venous-arterial loop under general anesthesia. The immediate post-operative trans-pulmonary valve pressure gradient was (35±6) mmHg (1 mmHg=0.133 kPa), with a significant reduction in RVSP from (96±16) mmHg to (59±14) mmHg ( t=6.70, P<0.001). SpO 2 (with an inspired oxygen concentration of 0.48) increased from 0.86±0.07 pre-operatively to 0.97±0.03 post-operatively ( t=4.81, P<0.001). One month postoperatively, SpO 2 (without oxygen supplementation) normalized in all patients, with a statistically significant difference compared to pre-operative values ( t=0.16, P<0.001). Immediately postoperative, mild to moderate diastolic pulmonary valve regurgitation was observed in 8 patients, with no cases of severe regurgitation. Additionally, the severity of tricuspid valve regurgitation decreased from severe to mild-to-moderate in 6 patients. Three months postoperatively, one patient underwent a second PBPV due to an increased trans-pulmonary valve pressure gradient of 74 mmHg, which decreased to 27 mmHg immediately after the procedure, with subsequent good recovery. Over a one-year follow-up period, all 15 patients demonstrated improvements in right ventricular indices. The Z-score of the tricuspid valve annulus significantly improved from -1.9±0.8 pre-operatively to -0.4±0.1 post-operatively ( t=6.88, P<0.001). At the last follow-up, mild to moderate pulmonary valve regurgitation was observed in 3 patients, and mild tricuspid regurgitation in 2 patients, with no cases of moderate or severe regurgitation. Conclusion:Intervention via antegrade venous-arterial loop for the treatment of CPS-IVS in neonates is safe and effective.

Objective:To investigate the feasibility of ductus arteriosus (DA) stent placement through femoral artery approach without guiding catheter.Methods:In this retrospective case study, the birth weight, intervention age, preoperative echocardiography, intraoperative angiography and other clinical data, as well as the follow-up status (Nakata index and final circulatory status, etc.) of 15 patients with congenital heart disease who are dependent on the DA for pulmonary circulation at Women and Children′s Hospital, Qingdao University between January 2018 to June 2023 were collected. All pediatric patients underwent placement of a DA stent without a guiding catheter, the efficacy and safety of this approach were analyzed.Results:Among all 15 cases, there were 9 males and 6 females, with the birth weight of (3.3±0.3) kg and the intervention age of (15.0±0.1) d. Of which, there were 9 cases of pulmonary atresia with intact ventricular septum (PA-IVS), and 6 cases of critical pulmonary stenosis (CPS) with intact ventricular septum. The tricuspid annulus diameter before intervention was (8.8±0.8) mm, and the tricuspid annulus Z-score was -0.7±0.9. There were 3 cases of mild right ventricular dysplasia, 9 cases of moderate dysplasia, and 3 cases of severe dysplasia. All patients successfully completed the intervention without major complications. The narrowest diameter of the DA was (2.2±0.1) mm, the diameter of the DA stent was (3.9±0.3) mm, the preoperative percutaneous oxygen saturation (SpO 2) was 0.83±0.03, and the postoperative SpO 2 was 0.96±0.02. The follow-up time was (7.0±0.5) months. The Nakata index was (163±30) mm 2/m 2 before intervention, and was (173±34) mm 2/m 2 at the last follow-up. Biventricular circulation was successfully achieved in 14 patients, and the other one patient currently under close observation. Conclusion:The placement of a ductus arteriosus stent through femoral artery retrogradely without guiding catheter could serve as an effective and safe plan for neonates with PA-IVS or CPS accompanied by hypoplastic right heart syndrome.

Objective:To evaluate the clinical characteristics and prognosis of transcatheter closure of secundum atrial septal defect (ASD) in infants.Methods:A retrospective analysis was conducted on 83 cases with secundum ASD who underwent transcatheter closure at the Women and Children′s Hospital of Qingdao University from January 2010 to December 2021. The clinical data included general information, pre- and post-operative echocardiography and electrocardiography, surgery records, and follow-up outcomes. The children who underwent successful occlusion were divided into two groups based on the presence or absence of pulmonary hypertension: the normal group and the pulmonary hypertension group. Differences between the two groups in terms of age, weight, right ventricular end-diastolic diameter, maximum ASD diameter, occluder size, and pulmonary-to-systemic flow ratio (Qp/Qs) were compared. Intergroup comparisons were performed using the Wilcoxon test.Results:Among the 83 infants with secundum ASD, 12 were males and 71 were females, with the age of (10.8±1.6) months. There were 29 cases (35%) with weight-for-age below the median level (less than the 25th percentile), 19 cases (23%) with recurrent or refractory pulmonary infections, and 40 cases (48%) with pulmonary hypertension. In this study, 81 cases (97%) successfully completed the procedure, while 2 cases failed due to soft defect margins. Postoperative arrhythmias occurred in 12 cases, of which 11 were transient arrhythmia; one case of atrioventricular block returned to normal rhythm after surgical removal of the occluder. The 81 infants who underwent successful occlusion were divided into normal group (41 cases) and pulmonary hypertension group (40 cases). The pulmonary artery systolic pressure, maximum diameter of ASD, the size of the occluder, and the cardiothoracic ratio were higher in the pulmonary hypertension group compared to those in the normal group, while the Qp/Qs value was lower (all P<0.05). Follow-up results indicated that infants with ASD who underwent transcatheter closure had no new arrhythmias, residual shunts, or intervention-related mortality. Within one year postoperatively, all infants exhibited normalization of right ventricular dimensions and pulmonary artery pressure. During a 3-year follow-up, all 29 cases that originally had a weight-for-age below the median level exhibited catch-up growth, reaching above the median level. Conclusions:Transcatheter closure for secundum ASD in infants is safe and feasible. Follow-up indicates that early transcatheter closure may be necessary for larger ASD diameters combined with pulmonary hypertension, with significant clinical improvement postoperatively.
