ObjectiveTo elucidate the efficacy connotation of Shudi Qiangjin pills (SQP) against liver and kidney deficiency in steroid-induced osteonecrosis of femoral head (SONFH) from the perspective of the "disease-syndrome-formula" association and to clarify the underlying mechanisms based on in vivo and in vitro experiment validation. MethodsThe chemical components and the corresponding putative targets of SQP were collected from the Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP) v2.0, the Encyclopedia of Traditional Chinese Medicine (ETCM) v2.0, and HERB databases. The SONFH-related genes were identified based on the differential expression profiles of peripheral blood of patients with SONFH compared to the healthy volunteers, and the disease phenotype-related targets were collected from the TCMIP v2.0 database. Then, the interaction network of "SONFH-related genes and candidate targets of SQP" was constructed based on "gene-gene interaction information", and the major network targets were screened by calculating the topological characteristic values of the network followed by the functional mining according to the Kyoto Encyclopedia of Genes and Genomes (KEGG) database and the SoFDA database. After that, the SONFH rat model was prepared by lipopolysaccharide combined with methylprednisolone injection, and 2.5, 5, 7.5 g·kg-1 SQP (once per day, equivalent to 1, 2, and 3 times the clinical equivalent dose, respectively) or 7.3×10-3 g·kg-1 of alendronate sodium (ALS, once per week, equivalent to the clinical equivalent dose) was given for 8 weeks. The effect characteristics of SQP and ALS in the treatment of SONFH were evaluated by micro-computed tomography scanning, hematoxylin and eosin staining, alkaline phosphatase (ALP) staining, immunohistochemical staining, enzyme-linked immunosorbent assay, and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL)staining, and a comparative efficacy analysis was conducted with ALS. In addition, SONFH cell models were prepared by dexamethasone stimulation of osteoblasts, and the intervention was carried out with the medicated serum of SQP at the aforementioned three doses. Cell counting kit-8, ALP staining, ALP activity assay, alizarin red staining, and flow cytometry were employed to investigate the regulatory effect of SQP on osteoblasts. The expression levels of osteogenesis-related proteins and key factors of the target signaling axis were detected by quantitative real-time polymerase chain reaction and Western blot. ResultsThe network analysis results demonstrated that the candidate targets of SQP primarily exerted their therapeutic effects through key signaling pathways, including phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt), lipid metabolism and atherosclerosis, prolactin, chemokines, and neurotrophic factors pathways. These pathways were significantly involved in critical biological processes such as muscle and bone metabolism and the regulation of the "neuro-endocrine-immune" network, thereby addressing both modern medical symptoms (e.g., delayed skeletal maturation and recurrent fractures) and traditional Chinese medicine (TCM) symptoms (e.g., fatigue, aversion to cold, cold limbs, and pain in the limbs and joints in patients with SONFH characterized by liver and kidney deficiency syndrome. Among these pathways, the PI3K/Akt signaling pathway exhibited the highest degree of enrichment. The in vivo experimental results demonstrated that starting from the 4th week after modeling, the modeling group exhibited a significant reduction in body weight compared to the control group (P<0.05). After six weeks of treatment, all dosage groups of SQP showed significantly higher body weights compared to the model group (P<0.01). Compared with the normal group, the model group exhibited significant decreases in bone mineral density (BMD), bone volume fraction (BV/TV), trabecular number (Tb.N), osteocalcin (OCN), alkaline phosphatase (ALP) levels in femoral head tissue, and serum bone-specific alkaline phosphatase (BALP) (P<0.01), along with significant increases in trabecular separation (Tb.Sp), empty lacunae rate in tissue, and apoptosis rate (P<0.01). In comparison to the model group, the SQP intervention groups showed significant improvements in BMD, BV/TV and Tb.N (P<0.01), significant reductions in Tb.Sp, empty lacunae rate and apoptosis rate (P<0.05), and significant increases in protein levels of OCN and ALP as well as BALP content (P<0.05). The in vitro experimental results revealed that all dosage groups of SQP medicated serum showed no toxic effects on osteoblast. Compared with the normal group, the model group displayed significant suppression of osteoblast proliferation activity, ALP activity, and calcified nodule formation rate (P<0.01), significant decreases in mRNA transcription levels of OCN and Runt-related transcription factor 2 (RUNX2) (P<0.01), significant reductions in protein content of osteopontin (OPN), typeⅠ collagen (ColⅠ)A1, B-cell lymphoma-2 (Bcl-2), PI3K, and phosphorylated (p)-Akt (P<0.01), and a significant increase in apoptosis rate (P<0.01). Compared with the model group, the SQP medicated serum intervention groups exhibited significant increases in proliferation activity, ALP activity, calcified nodule formation rate, mRNA transcription levels of OCN and RUNX2, and protein content of OPN, ColⅠA1, Bcl-2, PI3K, and p-Akt (P<0.05), along with a significant decrease in apoptosis rate (P<0.01). ConclusionSQP can effectively reduce the disease severity of SONFH with liver and kidney deficiency syndrome and improve bone microstructure, with the therapeutic effects exhibiting a dose-dependent manner. The mechanism may be related to its regulation of key processes such as muscle and bone metabolism and the correction of imbalances in the "neuro-endocrine-immune" network, thereby promoting osteoblast differentiation and inhibiting osteoblast apoptosis. The PI3K/Akt signaling axis is likely one of the key pathways through which this formula exerts its effects.

AIM: To compare the preoperative ocular biometry between Pentacam AXL and IOL Master 700 in cataract patients.METHODS:Prospective study. A total of 150 patients(150 eyes)with cataracts who were treated in our hospital from May to December 2024 were selected. The IOL Master 700 and Pentacam AXL were preoperatively used to measure axial length(AL), corneal curvature(K1, K2 and Km), anterior chamber depth(ACD), and white-to-white(WTW). The difference and consistency of the results of the two instruments were compared.RESULTS: There was no significant difference between the two instruments in the AL, K1, K2, Km, ACD, and WTW(all P>0.05). The Spearman correlation analysis showed that the two instruments positively correlated with the AL, K1, K2, Km, ACD and WTW of the operated eye(all P<0.001). The Bland-Altman analysis showed that for the Pentacam AXL and IOL Master 700, there were 5/150(3.3%), 7/150(4.7%), 4/150(2.7%), 5/150(3.3%), and 0 points outside the 95%LoA for the AL, K1, K2, Km, ACD, and WTW of the examined eyes, respectively, with all of these values less than 5%, indicating good consistency.CONCLUSION:The AL, K1, K2, Km, ACD and WTW of Pentacam AXL and IOL Master 700 in cataract patients before cataract phacoemulsification combined with IOL implantation show no significant differences, and have good correlation and consistency. The two instruments can be used interchangeably.

In recent years, with the extensive application of traditional Chinese medicine (TCM) both domestically and internationally, safety concerns associated with TCM have been frequently reported. Notably, some TCM substances traditionally regarded as ''non-toxic'' have exhibited significant adverse reactions during clinical use, drawing substantial attention to TCM safety. This study first analyzed the risk factors contributing to the potential toxicity of TCM from perspectives such as drug properties, individual constitution, and clinical medication practices. Subsequently, it proposed research strategies and methodologies for investigating potential TCM toxicity: ① conduct studies under the guidance of TCM theory, adhering to the principle of diversity and unity. ② adopt an integrated research paradigm of ''originating from clinical practice-syndrome-based foundation-returning to clinical practice-serving supervision''. ③ implement a three-tier technical system of ''Mathematical modeling-high-throughput screening via liquid chromatography-mass spectrometry (LC-MS)-systems biology'' to systematically elucidate the causes, material basis, and mechanisms of toxicity. Finally, scientific regulatory recommendations for potential TCM toxicity are proposed: ① establish a multidimensional prevention and control system addressing drug properties, physical constitution factors, and clinical medication practices. ② address the impact of modern processing techniques on the safety of new TCM drugs. ③ strengthen the revision of standards for Chinese medicinal materials to ensure their safety. ④ account for disease-syndrome combination animal models and interspecies differences in safety assessment outcomes. This study aims to overcome critical challenges in TCM regulation by advancing evaluation through research and driving research through evaluation. By establishing a high-level scientific regulatory framework, it seeks to not only safeguard clinical medication safety but also propel the high-quality development of the TCM industry, thereby providing scientific support for the inheritance and innovative evolution of TCM.

OBJECTIVE To provide technical support for improving recognition rate of adverse drug events (ADEs) related to traditional Chinese medicine (TCM) formula granules and decoction pieces among inpatient patients. METHODS By referencing the global trigger tool (GTT) whitepaper, literature on adverse reactions to TCM, and expert review opinions, ADE trigger items for TCM formula granules and decoction pieces used in the inpatients were established. GTT was applied to analyze ADEs in inpatients who had used TCM formula granules and decoction pieces in our hospital from August 2013 to August 2023, utilizing the Chinese Hospital Pharmacovigilance System. The effectiveness of GTT and the characteristics of these ADEs were analyzed. RESULTS A total of forty-eight triggers were established, including thirty-two laboratory test indexes, thirteen clinical symptoms, and three antidotes. Among the 1 682 patients included, GTT identified 652 potential ADEs, 284 true positive ADEs,with a trigger rate of 38.76% and a positive predictive value of 43.56%. After review by the auditor, 278 cases of ADEs were finally confirmed, with an incidence rate of 16.53%, significantly higher than the number of spontaneously reported ADEs during the same period (0). The 278 cases of ADEs were mostly grade 1 (223 cases), mainly involving hepatobiliary system, gastrointestinal system, blood- lymphatic system, etc;a total of 219 types of TCMs are involved,and the top five suspected TCMs used at a frequency higher than 1% were Poria cocos, Codonopsis pilosula, Atractylodes macrocephala, fried Glycyrrhiza uralensis, and Scutellaria baicalensis. CONCLUSIONS The established GTT can improve the recognition rate of ADEs for hospitalized patients using traditional Chinese medicine formula granules and decoction pieces.

Objective:To investigate the risk factors associated with post-prematurity respiratory disease (PPRD) in very preterm infants.Methods:A prospective cohort study was conducted, enrolling 369 very preterm infants who were admitted to the neonatal intensive care unit of Xinhua Hospital, Shanghai Jiao Tong University School of Medicine, within one week of birth from January 2019 to June 2023. Data on maternal and infant clinical characteristics, neonatal morbidities, and treatments during hospitalization were collected. The very preterm infants were divided into 2 groups based on whether they developed PPRD. Continuous variables were compared using Mann-Whitney U test, while categorical variables were compared using χ2 tests or continuity correction χ2 test. Multivariate Logistic regression analysis was used to identify the independent risk factors for PPRD in very preterm infants. Results:Among the 369 very preterm infants, 217 cases(58.8%) were male, with a gestational age of 30 (28, 31) weeks at birth and a birth weight of 1 320 (1 085, 1 590) g. Of these, 116 cases (31.4%) developed PPRD, while 253 cases (68.6%) did not. The very preterm infants in the PPRD group had a lower gestational age and lower birth weight (both, P<0.001). The PPRD group also had a higher proportion of males, lower Apgar scores at the 1 th minute after birth and the 5 th minutes after birth, a higher rate of born via cesarean delivery, and a higher incidence of bronchopulmonary dysplasia, more pulmonary surfactant treatment, longer durations of mechanical ventilation, longer total oxygen therapy, and lower Z-score for weight at discharge (all P<0.05). Multivariate Logistic regression analysis showed that gestational age ( OR=0.85, 95% CI 0.73-0.99, P=0.037), born via cesarean delivery ( OR=2.23, 95% CI 1.21-4.10, P=0.010), a duration of mechanical ventilation ≥7 days ( OR=2.51, 95% CI 1.43-4.39, P=0.001), and a Z-score for weight at discharge ( OR=0.82, 95% CI 0.67-0.99, P=0.040) were all independent risk factors for PPRD in very preterm infants. Conclusion:Very preterm infants with a small gestational age, born via cesarean section, mechanical ventilation ≥7 days, and a low Z-score for weight at discharge should be closely monitored for PPRD, and provided with standardized respiratory management after discharge.
