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.

ObjectiveTo explore the effects of compatibility of Ephedrae Herba,Asari Radix et Rhizoma, and Aconiti Lateralis Radix Praeparata on the expression of type 2 innate lymphoid cells(ILC2s)-related factors in the lung of allergic rhinitis(AR)mice. MethodsAccording to the random number table method,fifty-four C57BL/6J mice were randomly divided into the following groups: Blank group,model group,Mahuang Fuzi Xixintang group,Asari Radix et Rhizoma and Aconiti Lateralis Radix Praeparata group,Ephedrae Herba and Asari Radix et Rhizoma group,Ephedrae Herba and Aconiti Lateralis Radix Praeparata group,Ephedrae Herba group,Aconiti Lateralis Radix Praeparata group, and Asari Radix et Rhizoma group (6 mice in each group). Except the blank group,the other groups were subjected to intraperitoneal injection of ovalbumin(OVA)and intranasal challenge to induce AR. After the AR model was established,the mice in the blank group and the model group were given 0.2 mL·d-1 normal saline by gavage,while those in the Mahuang Fuzi Xixintang group(2.31 g·kg-1),Asari Radix et Rhizoma and Aconiti Lateralis Radix Praeparata group(1.54 g·kg-1), Ephedrae Herba and Asari Radix et Rhizoma group(1.16 g·kg-1), Ephedrae Herba and Aconiti Lateralis Radix Praeparata group(1.93 g·kg-1),Ephedrae Herba group(0.77 g·kg-1),Aconiti Lateralis Radix Praeparata group(1.16 g·kg-1),and Asari Radix et Rhizoma group(0.39 g·kg-1)were given corresponding medicine by gavage,with the treatment lasting for 14 consecutive days. The survival state of mice in each group was observed, and the levels of serum immunoglobulins E(IgE)after intranasal challenge were measured by enzyme-linked immunosorbent assay(ELISA). The pathological changes of nasal and lung tissues were observed by hematoxylin-eosin(HE)staining. The expression of ILC2s in lung tissue of mice was detected by immunofluorescence(IF). The mRNA expression of GATA binding protein 3(GATA3),retinoic acid receptor-related orphan receptor-α(RORα), and inhibitor of DNA binding 2(ID2)in the lung tissue of mice was detected by quantitative real-time polymerase chain reaction(real-time PCR). The levels of IgE,interleukin(IL)-4,IL-5, and IL-13 in serum were detected by ELISA. ResultsCompared with the blank group,the model group had poor survival state of mice and significantly increased serum IgE level after intranasal challenge(p<0.01). Additionally,the mice in the model group showed a large amount of neutrophil infiltration in the mucosa of the posterior turbinate, obvious nasal mucosal bleeding and purulent secretion,shed epithelium, thickened bronchial wall,obvious intravascular hyperemia and edema,diffusion and infiltration of a large number of inflammatory cells,seriously damaged alveolar structure,and local lung consolidation. The model group also exhibited significantly increased expression of ILC2s in the lung tissue(P<0.01),increased mRNA expression of GATA3 and RORα,decreased mRNA expression of ID2(P<0.05,P<0.01),and increased levels of serum IgE, IL-4,IL-5,and IL-13(P<0.05,P<0.01). Compared with the model group,the Mahuang Fuzi Xixintang group and the other medicine treatment groups showed improved survival state of mice, significantly reduced inflammatory cell infiltration in the nasal and lung tissues,a small amount of nasal mucosal bleeding,trachea wall thinning,and no hyperemia,edema, and nasal secretions. Furthermore, the expression of ILC2s in lung tissue was significantly decreased(P<0.01). The mRNA expression level of GATA3 was decreased(P<0.05),especially in the Aconiti Lateralis Radix Praeparata group(P<0.01). The expression mRNA levels of RORα were decreased only in the Ephedrae Herba and Aconiti Lateralis Radix Praeparata group and the Ephedrae Herba group(P<0.05). The levels of serum IgE were decreased(P<0.05), and IL-5 levels were significantly decreased(P<0.01). IL-4 levels were significantly decreased in the groups except the Aconiti Lateralis Radix Praeparata group(P<0.01),and the level of IL-13 in the Mahuang Fuzi Xixintang group was decreased(P<0.05). The levels of IL-13 in were significantly decreased in the Ephedrae Herba and Aconiti Lateralis Radix Praeparata group, Ephedrae Herba group, Aconiti Lateralis Radix Praeparata group, and Asari Radix et Rhizoma group(P<0.01). ConclusionDifferent compatibility of Ephedrae Herba,Asari Radix et Rhizoma, and Aconiti Lateralis Radix Praeparata can reduce the inflammation of OVA-induced AR mice and has more advantages in reducing the secretion of IgE and IL-5. The compatibility of Ephedrae Herba and Aconiti Lateralis Radix Praeparata has the most advantage in reducing the mRNA expression of GATA3 and RORα to inhibit the expression of ILC2s and thus exert the anti-allergic effect,while the other compatibility has the extensive advantage in inhibiting the mRNA expression of GATA3.

Abstract
Modern western medicine typically focuses on treating specific symptoms or diseases, and traditional Chinese medicine (TCM) emphasizes the interconnections of the body’s various systems under external environment and takes a holistic approach to preventing and treating diseases. Phenomics was initially introduced to the field of TCM in 2008 as a new discipline that studies the laws of integrated and dynamic changes of human clinical phenomes under the scope of the theories and practices of TCM based on phenomics. While TCM Phenomics 1.0 has initially established a clinical phenomic system centered on Zhenghou (a TCM definition of clinical phenome), bottlenecks remain in data standardization, mechanistic interpretation, and precision intervention. Here, we systematically elaborates on the theoretical foundations, technical pathways, and future challenges of integrating digital medicine with TCM phenomics under the framework of “TCM phenomics 2.0”, which is supported by digital medicine technologies such as artificial intelligence, wearable devices, medical digital twins, and multi-omics integration. This framework aims to construct a closed-loop system of “Zhenghou–Phenome–Mechanism–Intervention” and to enable the digitization, standardization, and precision of disease diagnosis and treatment. The integration of digital medicine and TCM phenomics not only promotes the modernization and scientific transformation of TCM theory and practice but also offers new paradigms for precision medicine. In practice, digital tools facilitate multi-source clinical data acquisition and standardization, while AI and big data algorithms help reveal the correlations between clinical Zhenghou phenomes and molecular mechanisms, thereby improving scientific rigor in diagnosis, efficacy evaluation, and personalized intervention. Nevertheless, challenges persist, including data quality and standardization issues, shortage of interdisciplinary talents, and insufficiency of ethical and legal regulations. Future development requires establishing national data-sharing platforms, strengthening international collaboration, fostering interdisciplinary professionals, and improving ethical and legal frameworks. Ultimately, this approach seeks to build a new disease identification and classification system centered on phenomes and to achieve the inheritance, innovation, and modernization of TCM diagnostic and therapeutic patterns.

Objective To analyze the clinical characteristics of immune checkpoint inhibitor (ICI)-related hypophysitis. Methods A retrospective analysis was conducted on patients diagnosed with ICI-related hypophysitis and treated at the Department of Endocrinology, The First Affiliated Hospital with Nanjing Medical University, between January 2020 and March 2025. Clinical manifestations and prognosis of patients were analyzed. Results Eleven patients with ICI-related hypophysitis were included. The average age was (62.27±7.63) years, and 9 patients (81.82%) were male. The median time to onset was 9.1 months, and the median number of treatment cycles received was 5. The primary initial symptoms were fatigue and anorexia. Hyponatremia was present in 3 patients (27.27%). Evaluation of anterior pituitary function revealed adrenocorticotropic hormone deficiency as the most common manifestation (90.91%, 10/11), followed by hyperprolactinemia (81.82%, 9/11). Posterior pituitary function remained normal in all patients. Pituitary magnetic resonance imaging showed no abnormality in 4 patients (44.44%). Thyroid dysfunction was observed in 6 patients (54.55%), one of whom (9.09%) also exhibited pancreatic endocrine dysfunction. The average follow-up duration was 36.5 months. Eight patients (72.73%) were alive at the last follow-up. None of the patients recovered their pituitary hormone function. Conclusions Endocrine adverse events induced by ICIs can involve multiple glandular systems. Clinicians should be highly vigilant for the possibility of ICI-induced hypophysitis in patients receiving ICIs who present with symptoms such as fatigue, anorexia, and hyponatremia.

The Philippines has an increasingly aging population thereby increasing the demand for healthcare and support from families. Studies showed that the family is the main caregiver of elderly parents/adults as dictated by the Filipino culture of filial piety and respectful behavior towards older people. However, this caring culture is now slowly declining, and Filipino older adults also experience abuse, exploitation, and other forms of neglect from their families. This special article described that the declining caring culture was due to deteriorating family values and societal influences brought about by modernization. This paper also highlights the crucial role of the family and the community in inculcating the preservation of this valued caring Filipino culture, especially among the youth. In cases where senior citizens are being abused and neglected by their families, the state steps in to safeguard the welfare and protection of Filipino senior citizens. Enacted and promulgated laws ensure social justice and protection of human dignity among Filipino older adults as well as the provision of socioeconomic and health needs. In conclusion, the preservation of a caring culture through educating the youth coupled with the implementation of enacted and promulgated laws of the country ensures the quality of aging life among Filipino older adults.
