OBJECTIVE: By analyzing the hormone secretion of the adenohypophysis, thyroid glands, gonads, and adrenal cortex in patients with hematological diseases before and after hematopoietic stem cell transplantation (HSCT), this study aims to preliminarily explore the effect of HSCT on patients' hormone secretion and glandular damage. METHODS: The baseline data of 209 hematological disease patients who underwent HSCT in our hospital from January 2019 to December 2023, as well as the data on the levels of hormones secreted by the adenohypophysis, thyroid glands, gonads and adrenal cortex before and after HSCT were collected, and the changes in hormone levels before and after transplantation were analyzed. RESULTS: After allogeneic HSCT, the levels of thyroid-stimulating hormone (TSH), triiodothyronine (T3), free triiodothyronine (FT3) and estradiol (E2) decreased, while the levels of luteinizing hormone (LH) and follicle- stimulating hormone (FSH) increased. The T3 level of patients with decreased TSH after transplantation was lower than that of those with increased TSH after transplantation. In female patients, the levels of prolactin (PRL), progesterone (Prog), and testosterone (Testo) decreased after HSCT. Testo and PRL decreased when there was a donor-recipient sex mismatch, and the levels of adrenocorticotropic hormone (ACTH) and cortisol (COR) decreased when the HLA matching was haploidentical. The levels of T3, FT3, and PRL decreased after autologous HSCT. In allogeneic HSCT patients, the levels of TSH, T4, T3, FT3, and ACTH in the group with graft-versus-host disease (GVHD) were significantly lower than those in the group without GVHD. Logistic regression analysis showed the changes in hormone levels after transplantation were not correlated with factors such as the patient's sex, age, or whether the blood types of the donor and the recipient are the same. CONCLUSION HSCT can affect the endocrine function of patients with hematological diseases, mainly affecting target glandular organs such as the thyroid, gonads, and adrenal glands, while the secretory function of the adenohypophysis is less affected.

Metastasis serves as an indicator of malignancy and is a biological characteristic of carcinomas. Epithelial-mesenchymal transition (EMT) plays a key role in the promotion of tumor invasion and metastasis and in the enhancement of tumor cell aggressiveness. Prostaglandin E synthase 3 (p23) is a cochaperone for heat shock protein 90 (HSP90). Our previous study showed that p23 is an HSP90-independent transcription factor in cancer-associated inflammation. The effect and mechanism of action of p23 on lung cancer metastasis are tested in this study. By utilizing cell models in vitro and mouse tail vein metastasis models in vivo, the results provide solid evidence that p23 is critical for promoting lung cancer metastases by regulating downstream CXCL1 expression. Rather than acting independently, p23 forms a complex with RNA-binding motif protein 14 (RBM14) to facilitate EMT progression in lung cancer. Therefore, our study provides evidence for the potential role of the RBM14-p23-CXCL1-EMT axis in the metastasis of lung cancer.

Objective:To systematically evaluate the qualitative research on experience of fear of falling in the elderly, so as to provide theoretical basis for nursing practice.Methods:Qualitative researches on the fear of falling among the elderly were systematically searched in PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure, WanFang Data, VIP, and China Biology Medicine disc. The search period was from database establishment to November 5, 2023. The quality of literature was evaluated using the quality evaluation criteria for qualitative research of the Australia Joanna Briggs Institute Evidence-Based Health Care Center, and the results were integrated using the Meta-synthesis.Results:A total of 13 articles were included, 44 themes were extracted, categorized into 12 categories, and refined into four integrated results, namely perception of fear of falling, influencing factors of fear of falling, coping strategies in attitude and behavior, and multidimensional needs for rehabilitation nursing.Conclusions:Medical and nursing staff should pay attention to and understand the fear of falling among the elderly, evaluate their fear of falling from multiple dimensions and dynamically, provide personalized guidance based on coping behaviors, create support systems to alleviate their fear of falling and meet their multidimensional needs, so as to improve their quality of life.

Objective:To investigate the alterations in soft tissue morphology and thickness in the mid-face region of patients with cleft lip and palate (UCLP) secondary to maxillofacial deformity following Le Fort I osteotomy.Methods:A total of 22 patients (16 males and 6 females aged from 17 to 28 years with an average of 20 years) diagnosed with cleft lip and palate secondary to maxillofacial deformity were collected from the Wuhan University Hospital of Stomatology from July 2012 to August 2020. All patients underwent Le Fort I osteotomy. CBCT scans were obtained at T0 (3 days before surgery), T1 (7 days after surgery), and T2 (1 year after surgery). The Dolphin11.95 software and 3D Slicer software were utilized to measure and analyze the soft tissue near the mid-face osteotomy line. Differences in soft tissue thickness before and after surgery were compared.Results:Before and after the operation, the soft tissue thickness at P3, P5, P6, and P8 on the affected side was thicker than that on the healthy side, and the difference was statistically significant, with a P-value of <0.05. At P5, P6, P7, P8, and P9 below the osteotomy line at T2-T0, the degree of postoperative thinning on the affected side was more apparent than that on the healthy side, and there was statistical significance at P6 ( P<0.05). The postoperative soft tissue asymmetry in the Ck region was improved compared with the preoperative one. The preoperative average protruding of the affected side was 0.63 compared with the healthy side, and the postoperative value was 0.17. The preoperative and postoperative Mann-Whitney U tests showed significantly statistical difference. Conclusions:After Le Fort I osteotomy, the facial asymmetry of patients with unilateral cleft lip and palate secondary to maxillofacial deformity is improved. However, there is still a difference in the soft tissue thickness between the healthy side and the affected side, and the change in soft tissue thickness on the affected side is more significant than that on the healthy side.

Objective::To establish a pre-column derivatization reverse-phase high-performance liquid chromatography (RP-HPLC) method for the simultaneous determination of 17 amino acids in Cynomorii Herba from different producing areas and conduct a multivariate statistical analysis. Method::RP-HPLC with pre-column derivatization was employed, with phenyl isothiocyanate (PITC) as derivatization reagent. Separation was performed on a WondaSil C₁₈-WR column (4.6 mm×150 mm, 5 μm), with 0.05 mol·L^-1 sodium acetate solution (pH 6.5) as mobile phase A, and acetonitrile-methanol-water (3∶1∶1) as mobile phase B for gradient elution at a flow rate of 0.8 mL·min^-1. The detective wave length was set at 254 nm, and the column temperature was maintained at 35 ℃. Principal component analysis (PCA) and systematic cluster analysis (HCA) models were established for multivariate statistical analysis and quality evaluation. Result::17 Kinds of amino acid were detected in Cynomorii Herba, 7 of which were essential amino acids. The 17 amino acids showed good linearity in respective concentration range, r = 0.999 0-0.999 9.The average recoveries were between 98.03%-103.89%with RSD<3.5%. The results of PCA and HCA were basically the same, and both methods can be used to clearly distinguish Cynomorii Herba from 12 municipal producing areas into 6 regions. PCA can be used to classify Cynomorii Herba according to different municipal or provincial production areas, and HCA can be used to classify it according to provincial production areas. It showed that the amino acid contents in Cynomorii Herba from different municipal and provincial producing areas had differences, and the content distribution showed obvious geographical clustering characteristics. PCA showed that Cynomorii Herba from Gansu province and Inner Mongolia had higher amino acid contents and better quality as compared with other producing areas. Conclusion::The established method can be used for content determination of 17 amino acids in Cynomorii Herba from different producing areas, and provide a reference for its comprehensive quality evaluation.
