Informed consent constitutes a fundamental ethical principle in medical practice. With the in-depth integration of generative artificial intelligence (AI) represented by Chat Generative Pre-trained Transformer (ChatGPT) with medicine, it has brought revolutionary development to traditional informed consent while also introducing new ethical challenges. ChatGPT offers features such as improving the readability of informed consent content, enhancing its comprehensiveness and accuracy, and increasing the convenience of obtaining informed consent. However, as the application of ChatGPT in informed consent is still in the exploratory stage, it is imperative to proactively and fully consider the accompanying ethical issues, such as information security, liability determination, transparency, and fairness. This paper conducted an ethical analysis on the challenges faced by generative AI, represented by ChatGPT, in the application of informed consent and proposed countermeasures, such as upholding free and fully informed consent, strengthening the balance of rights and obligations in informed consent, and establishing a transparent and fair supervision mechanism. The aim was to promote the ethically compliant, orderly, and controllable development of generative AI in the field of medical informed consent.

ObjectiveThis study aims to compare the modeling effects of submaxillary gland antigen and salivary gland antigen in the establishment of Sjögren syndrome (SS) mouse models, and to characterize the phenotypic and immunological features of these models in comparison with spontaneous SS-prone non-obese diabetic (NOD)/LtJ mice. MethodsAdult C57BL/6J mice (equal numbers of males and females) were immunized with submaxillary gland antigen or salivary gland antigen, respectively, combined with Freund's adjuvant to induce SS models. Mice immunized with phosphate-buffered saline (PBS) combined with Freund's adjuvant served as the control group. Immunization was induced via multiple subcutaneous injections in the back with antigen combined with Freund's complete adjuvant (FCA) on Days 1 and 7. A booster immunization was administered via multiple subcutaneous injections in the back with antigen combined with Freund's incomplete adjuvant (FIA) on Day 14. Female NOD/LtJ mice were used as the spontaneous SS model group, with ICR mice as the corresponding control strain for comparative analysis. Body weight, water intake, and salivary flow rate of mice were dynamically monitored for 4 weeks. At the end of the experiment, tissue and serum samples were collected, the weights of submaxillary glands, thymus, and spleen were measured, and organ indices (organ-to-body weight ratios) were calculated. Pathological morphological analysis of the submaxillary gland and spleen was performed with hematoxylin and eosin (HE) staining. Serum interleukin-17 (IL-17) level was detected using enzyme-linked immunosorbent assay (ELISA). Real-time quantitative polymerase chain reaction was used to detect the mRNA expression levels of SS type A (SSA) and SS type B (SSB) in submaxillary gland tissues. ResultsFemale mice in the submaxillary gland antigen group exhibited significantly increased water intake (P<0.05) and reduced salivary flow rate (P<0.05) compared with the female control group. No statistically significant differences were observed in the submaxillary gland index, thymus index and spleen index (P>0.05). Focal lymphocytic infiltration was observed in the submaxillary glands, and the splenic marginal zone was enlarged. Serum IL-17 levels were significantly increased (P<0.05). There was no significant difference in submaxillary gland SSA/SSB expression levels (P>0.05). Compared with the female control group, female mice in the salivary gland antigen group showed no statistically significant differences in water intake, salivary flow rate, submaxillary gland index, and spleen index (P>0.05), whereas the thymus index was significantly reduced (P<0.01). Mild inflammatory cell infiltration and glandular atrophy were observed in the submaxillary glands, and the splenic white pulp and marginal zone were slightly enlarged. Serum IL-17 levels and submaxillary gland SSB mRNA expression levels were significantly increased (P<0.01), whereas no significant change was observed in submaxillary gland SSA expression levels (P>0.05). Compared with the male control group, mild submaxillary gland atrophy was observed in male mice in the submaxillary gland antigen group, whereas no obvious changes were found in other modeling-related indicators (P>0.05). Compared with the ICR control group, NOD/LtJ model mice exhibited elevated water intake (P<0.05), significantly reduced salivary flow rate (P<0.01), no significant differences in the submaxillary gland index or spleen index (P>0.05), but a significantly increased thymus index (P<0.05). Marked focal infiltration was observed in the submaxillary glands, the splenic marginal zone was obviously enlarged, and serum IL-17 concentrations as well as submaxillary gland SSA/SSB expression levels were significantly increased (P<0.05). ConclusionSubmaxillary gland antigen and salivary gland antigen can induce SS-related features in female C57BL/6J mice. The SS-related phenotype is more pronounced in the submaxillary gland antigen group than in the salivary gland antigen group, but weaker than that in spontaneously SS-prone female NOD/LtJ mice. Immunization of male C57BL/6J mice with submaxillary or salivary gland antigens fails to induce an obvious SS phenotype.

ObjectiveTo investigate the effect of Danggui Shaoyaosan on the expression of Toll-like receptor 4/nuclear factor-kappa B p65/NOD-like receptor protein 3 (TLR4/NF-κB p65/NLRP3) signaling pathway in the renal tissues of db/db mice with spontaneous diabetes, and to explore the potential mechanism by which Danggui Shaoyaosan alleviates inflammation in diabetic kidney disease (DKD). MethodsThirty db/db mice were divided into five groups: A model group, Danggui Shaoyaosan low- (16.77 g·kg-1·d-1), medium- (33.54 g·kg-1·d-1), and high-dose (67.08 g·kg-1·d-1) intervention groups, as well as an irbesartan group (0.025 g·kg-1·d-1) by the random number table method, with 6 mice in each group. Additionally, 6 db/m mice were assigned to the normal group. After 8 weeks of intervention, the following parameters were determined by corresponding methods: body weight, fasting blood glucose (FBG), 24-hour urinary protein (24 h-UTP), and serum creatinine (SCr) levels, renal histopathological analysis by hematoxylin-eosin (HE) staining, Masson staining, and periodic acid-Schiff (PAS) staining, the protein and mRNA expression levels of TLR4, NF-κB p65, NLRP3, tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-10 (IL-10), and interleukin-18 (IL-18) by Western blot and Real-time quantitative polymerase chain reaction (Real-time PCR), as well as TLR4, NF-κB p65, and NLRP3 protein expression in renal tissues by immunohistochemistry (IHC). ResultsCompared with the normal group, the model group exhibited increased body weight, FBG, 24 h-UTP, and SCr levels (P<0.05); disordered renal structure, thickened basement membrane, and interstitial inflammatory cell infiltration, elevated TLR4, NF-κB p65, NLRP3, TNF-α, IL-1β, IL-6, and IL-18 expression; as well as decreased IL-10 expression (P<0.05). Compared with the model group, these pathological changes and biochemical abnormalities were reversed in the medicine intervention groups to varying degrees (P<0.05). ConclusionDanggui Shaoyaosan may delay DKD progression by alleviating renal inflammatory response and reducing urinary protein excretion via modulating the TLR4/NF-κB p65/NLRP3 signaling pathway.

Objective: This study employed next-generation sequencing (NGS) for large-scale genotyping of 42 blood group systems in blood donors to evaluate its applicability in multi-system blood group identification and rare blood type repository construction, while exploring the complementary value of third-generation sequencing (TGS) in haplotype phasing and variant capture in regions with insufficient sequencing depth for ABO ambiguous samples. Methods: A total of 562 regular blood donors (median donation frequency 11 times) from a blood center were enrolled. NGS was used for genotyping of 42 blood group systems, with a focused analysis on 12 systems essential for rare blood type repository construction: MNS, Lutheran, Kell, Duffy, Kidd, Diego, Yt, Colton, Gerbich, Ok, H, and I. TGS was employed to resolve haplotype phasing (i. e., determining whether different mutation sites are located on the same chromosome) in 12 ABO samples with discrepancies between forward and reverse typing. Serological and genotyping results were compared for MNS, Duffy, Kidd, Lewis, and ABO systems. Results: NGS-based genotyping revealed that Fy (a-b+) in the Duffy system accounted for 0.87% (4/458), and Di (a+b+) in the Diego system accounted for 10.62% (31/292). The Lutheran, Kell, Yt, Colton, H, Ok, I, and Gerbich systems exhibited near-uniform phenotype distributions. Among the 12 ABO ambiguous samples, NGS yielded multiple possible genotype combinations in 5 cases due to inability to phase alleles, whereas TGS uniquely resolved the genotypes through long-read sequencing. In one case, NGS detected only 2 mutation sites due to insufficient sequencing depth, while TGS identified all 11 sites and assigned the A1 phenotype. Concordance rates between serology and genotyping were: Duffy 96.55% (140/145), ABO 96.43% (513/532), Kidd 94.17% (97/103), MNS 85.07% (57/67), and Lewis 68.18% (75/110). In the MNS system, 7 of 8 samples serologically typed as M+N+ but genotyped as M-N+ carried GYPB variants. Lewis discrepancies predominantly featured genotype Le (a-b+) with serological phenotypes of Le (a+b-), Le (a+b+), or Le (a-b-). The NGS platform completed sequencing of 192 samples within 2 weeks. Conclusion: The tiered genotyping strategy combining NGS, TGS, and serology enables multi-system blood group identification in large-scale blood donor populations. TGS provides complementary value in phasing ambiguous ABO samples and detecting variants in regions with insufficient sequencing depth. This study provides a technical framework and baseline frequency data for the expansion of a local rare blood type repository. However, standardization and cost-effectiveness of this strategy require further validation with expanded sample sizes, and serological confirmation should be retained for secretion status-related systems such as Lewis.

ObjectiveTo evaluate the clinical efficacy and safety of Wenshen Yangxue decoction combined with endometrial microstimulation in the treatment of infertile patients with polycystic ovary syndrome (PCOS, syndrome of kidney-Yang deficiency and blood stasis). MethodsA randomized, positive-drug parallel-controlled, open-label clinical study was conducted. A total of 240 infertile PCOS patients with the syndrome of kidney-Yang deficiency and blood stasis who met the inclusion and exclusion criteria were randomly assigned into 4 groups, with 60 patients in each group. The control group was treated with clomiphene citrate (50-100 mg·d-¹, orally for 5-10 consecutive days) for ovulation induction. On the basis of the therapy in the control group, the Wenshen group was additionally treated with Wenshen Yangxue decoction (250 mL, warm oral administration, twice daily, in the morning and evening), and the stimulation group received endometrial microstimulation during the early follicular phase. The combined group was treated with clomiphene citrate plus Wenshen Yangxue decoction (at the same dosages as aforementioned) and endometrial microstimulation. The course of treatment for all the groups was 3 menstrual cycles. The pregnancy rate, ovulation status, sex hormone levels, glucose metabolism indicators, coagulation function, endometrial thickness, traditional Chinese medicine (TCM) symptom scores, and adverse reactions were observed in each group. ResultsA total of 239 patients were included in the final analysis, with 59 patients in the Wenshen group and 60 patients in each of the other three groups. The pregnancy rates were 43.3%(26/60) in the combined group and 32.2%(19/60) in the Wenshen group, both significantly higher than that (10%) in the control group (χ2=17.56,P<0.01). Compared with the control group, the combined and Wenshen groups had increased mature follicle rates (P<0.01), while the Wenshen group showed a decreased luteinization rate (P<0.05). All the groups exhibited significant reductions in TCM symptom scores after treatment, and the Wenshen and combined groups had lower scores than the control group (P<0.01). No statistically significant difference was found in the incidence of adverse events among the four groups, and all the adverse events were mild. ConclusionWenshen Yangxue decoction combined with endometrial microstimulation can alleviate the TCM symptoms of infertile PCOS patients with the syndrome of kidney-Yang deficiency and blood stasis, promote follicular maturation and ovulation, increase the cumulative pregnancy rate, and has good safety. It can provide new clinical evidence for the integrated traditional Chinese and Western medicine treatment of PCOS infertility.

OBJECTIVE To preliminarily assess the horizontal sound localization and its influencing factors in patients with unilateral sudden sensorineural hearing loss during the acute phase.METHODS The azimuth discrimination test and azimuth identification test were completed,with the speech sound(65 dB SPL)as the stimulus.The minimum audible angle(MAA)and root-mean-square error(RMSE)were obtained,and the RMSE of the affected side and the healthy side were calculated respectively.According to the WHO(2021)hearing loss classification criteria,the data were analyzed based on the pure-tone average(PTA)of the affected ear.And the best resident hearing at each frequency of the affected ear was recorded.RESULTS The performance of the unilateral sudden sensorineural hearing loss patients in the sound localization varied greatly.Some performed close to the normal level,while others completely lost the ability to localize sound.The RMSE of the moderate hearing loss group(≥35 dB HL)was significantly higher than that of the normal hearing group(P<0.01),the MAA of the moderate to severe hearing loss group(≥50 dB HL)showed statistically significant differencescompared with normal hearing group(P<0.001).The RMSE of the affected side of patients in the severe and above hearing loss group was significantly larger than that of the healthy side.Regression analysis showed that the best resident hearing at each frequency of the affected ear was the most significant factor affecting MAA(R2=0.572,P<0.001)and RMSE(R2=0.768,P<0.001).CONCLUSION The horizontal sound localization of unilateral sudden sensorineural hearing loss patients in the acute phase varies greatly.When the PTA of the affected side reaches moderate hearing loss,the localization ability is significantly lower than that of normal-hearing individuals.The best resident hearing at each frequency of the affected ear is the key factor affecting the localization ability.

Lung cancer (LC) complicated with interstitial lung disease (ILD) is a relatively common comorbidity in clinical practice, and its management remains complex and challenging. As one of the primary treatment modalities for LC, radiotherapy carries a risk of inducing acute exacerbation of ILD and severe radiation pneumonitis; therefore, it should be used with caution in LC-ILD patients. Advances in radiotherapy technology now allow for more precise tumor targeting and better sparing of healthy lung tissues, potentially offering greater therapeutic benefits for these patients. In this article, current status and recent research progress in the application of radiotherapy in LC-ILD were reviewed, aiming to provide theoretical basis and reference for clinical practice.
