OBJECTIVES:
To explore the molecular mechanism by which lncRNA SNHG15 regulates proliferation, invasion and migration of lung adenocarcinoma cells.
METHODS:
The lncRNA microarray chip dataset GSE196584 and LncBase were used to predict the lncRNAs that interact with miR-30b-3p, and their association with patient prognosis were investigated using online databases, after which lncRNA nucleolar RNA host gene 15 (SNHG15) was selected for further analysis. The subcellular localization of lncRNA SNHG15 and its expression levels in normal human lung epithelial cells and lung adenocarcinoma cell lines were detected using fluorescence in situ hybridization and qRT-PCR. In cultured A549 cells, the changes in cell proliferation, migration, and invasion following transfection with a SNHG15 knockdown plasmid (sh-SNHG15), a miR-30b-3p inhibitor, or their co-transfection were assessed with EdU, wound healing, and Transwell assays. Bioinformatics analyses were used to predict the regulatory relationship between lncRNA SNHG15 and COX6B1, and the results were verified using Western blotting and rescue experiments in A549 cells transfected with sh-SNHG15, a COX6B1-overexpressing plasmid, or both.
RESULTS:
LncRNA SNHG15 was shown to target miR-30b-3p, and the former was highly expressed in lung adenocarcinoma, and associated with a poor patient prognosis. LncRNA SNHG15 was localized in the cytoplasm and expressed at higher levels in A549 and NCI-H1299 cells than in BEAS-2B cells. In A549 cells, lncRNA SNHG15 knockdown significantly inhibited cell migration, invasion and proliferation, and these changes were reversed by miR-30b-3p inhibitor. A regulatory relationship was found between lncRNA SNHG15 and COX6B1, and their expression levels were positively correlated (r=0.128, P=0.003). MiR-30b-3p knockdown obviously decreased COX6B1 expression in A549 cells, and COX6B1 overexpression rescued the cells from the inhibitory effects of lncRNA-SNHG15 knockdown.
CONCLUSIONS
LncRNA SNHG15 may compete with COX6B1 to bind miR-30b-3p through a ceRNA mechanism to affect proliferation, migration, and invasion of lung adenocarcinoma cells.

OBJECTIVES:
To elucidate the anti-aging effect of β-sitosterol (BS), an important component in the fruits of Alpinia oxyphylla Miq., in C. elegans and its regulatory effect on ETS-5 gene to modulate ferroptosis.
METHODS:
C. elegans treated with 10 µg/mL BS were monitored for survival time and changes in body length, motility, and reproductive function. The effect of ETS-5 gene knockdown on survival time of C. elegans was observed, and the changes in fat accumulation and lipid redox homeostasis in the transfected C. elegans were assessed using Oil Red O staining and by detecting MDA levels and the GSH/GSSG ratio. The mRNA expression levels of ferroptosis-related genes (FTN-1, GPX-1 and AAT-9) were detected using qPCR. The effects of BS treatment and ETS-5 knockdown on AAT-9 enzyme activity in C. elegans were examined. The effect of BS on nuclear localization of FEV (the human homolog of ETS-5) was validated in cultured human umbilical venous endothelial cells (HUVECs).
RESULTS:
Both BS treatment and ETS-5 knockdown significantly prolonged the lifespan, promoted lipid accumulation and reduced lipid peroxidation in C. elegans. ETS-5 knockdown resulted in upregulated expressions of the ferroptosis repressors GPX-1, AAT-9 and FTN-1 and increased the GSH/GSSG ratio in C. elegans.
CONCLUSIONS
BS inhibits ferroptosis in C. elegans by suppressing the expression of ETS-5 transcription factor and hence the activity of AAT-9 enzyme, a key gene for ferroptosis, which in turn prolongs the lifespan of C. elegans.

Objective:To examine the postoperative prosthesis-related complications, short-term surgical outcomes and patient satisfaction with breast reconstruction between patients who underwent endoscopic assisted versus conventional nipple sparing mastectomy and immediate prothesis breast reconstruction.Methods:This study was a retrospective cohort study. A retrospective analysis was performed on clinical data of 104 women with breast cancer who received nipple sparing mastectomy and immediate prothesis breast reconstruction from August 2021 to August 2022 at the Breast Tumor Center, Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University. They were divided into two groups according to the surgical approach. A total of 53 patients, aged (43.3±9.9) years (range: 25 to 66 years), underwent endoscopic nipple sparing mastectomy (E-NSM group) and immediate prothesis breast reconstruction. The other 51 patients aged (39.9±7.8) years (range: 25 to 54 years) underwent conventional open surgery (C-NSM group). Short-term surgical outcomes including operation time, postoperative hospital stay, postoperative blood loss, and postoperative drainage volume in 2 days were recorded. Patient satisfaction with breast reconstruction was compared using the Wilcoxon rank sum test. Postoperative prothesis-related complications were investigated to determine the experience to deal with them.Results:No postoperative prosthesis-related infection, prosthesis loss, or necrosis of the nipple-areola complex occurred in the E-NSM group, while 1 patient suffered from hematoma, whose wound was skinned with resuture after disinfection. Five patients in the C-NSM group had prosthesis-related infection, 2 of them received prosthesis removal surgery combined with sufficient antimicrobial agent, another one underwent surgery for subcutaneous placement of the drain, as well as antimicrobial agent therapy, and the rest of them healed up only with antimicrobial agent therapy. All recovered well after treatment. One patient recovered from necrosis of the nipple-areola complex through periodic iodophor disinfection and dressing which ended in improvement of necrotic areas, another patient who had hematoma accepted the same treatment mentioned above and also healed. All the patients mentioned above are now in stable conditions. Patients in the E-NSM group had higher satisfaction with the cosmetic results of the breast prosthesis implant than those in the C-NSM group ( Z=-4.511, P<0.01). Conclusions:Both surgical approaches were proven to be safe and effective with a low rate of postoperative prosthesis-related complications. Patients in the E-NSM group were more satisfied with the cosmetic results of breast reconstruction than those in the C-NSM group.

ObjectiveTo observe the clinical efficacy and relative mechanism of the Modified Wenshen Yixin Formula (温肾益心方加减, MWYF) as an auxiliary treatment of coronary heart disease (CHD) complicated with hypothyroidism of spleen-kidney yang deficiency. MethodsA total of 135 CHD patients complicated with hypothyroidism and spleen-kidney yang deficiency were included and divided into control group (67 cases) and experimental group (68 cases) according to the patients' wishes of herbal medicine administration. The control group was given conventional western medicine, while the treatment group was additionally given MWYF, 1 dose per day; both groups were treated for 8 weeks. The traditional Chinese medicine (TCM) syndrome scores, angina scores, SF-36 scores, thyroid function indicators including thyroid stimulating hormone (TSH), thyroxine (T4) and triiodothyronine (T3), as well as serum cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP), monocyte chemoattractant ligand 2 (CCL2), and tumor necrosis factor-related activator protein (CD40L) levels before and after treatment were compared between the two groups. The dosage and reduction and discontinuation rate of thyroid hormone preparations after treatment were compared between the two groups. The effectiveness regarding TCM syndrome and angina pectoris was evaluated, and the safety was assessed. ResultsBias was adjusted by matching on propensity score, and 102 cases were finally included in the statistical analysis, with 51 cases in each group. The total effective rate regarding TCM syndrome [94.12% (48/51) versus 64.71% (33/51)], the total effective rate regarding angina pectoris [80.39% (41/51) versus 62.75% (32/51)], and the reduction and discontinuation rate of thyroid hormone preparation [39.21% (20/51) versus 5.88% (3/51)] were significantly higher in the experimental group than those in the control group (P<0.05 or P<0.01). After treatment, the total TCM syndrome score, individual scores of major symptoms , the major symptoms score, the secondary symptoms score, angina pectoris score, and TSH level were significantly reduced (P<0.01), while all dimensions of SF-36 scores, T4, T3, and cAMP levels significantly increased in both groups (P<0.05 or P<0.01). The dosage of thyroid hormone preparations and the levels of cGMP, CCL2, and CD40L in the experimental group significantly decreased after treatment (P<0.01). When compared between the two groups after treatment, the total TCM syndrome score, the major symptoms score, the scores of individual major symptom (chest tightness, chest pain, fear of cold, cold limbs, waist and kness soreness and weakness), the secondary symptoms score, angina pectoris score, TSH, cGMP, CCL2, and CD40L levels of the experimental group were significantly lower than those of the control group (P<0.05 or P<0.01), while all dimension scores of SF-36, T4, T3, and cAMP levels were significantly higher (P<0.01). A total of three adverse events occurred during treatment, none of which were judged to be related to the interventions of this study. ConclusionMWYF can significantly ameliorate the TCM syndrome, angina pectoris, quality of life and thyroid function in CHD patients complicated with hypothyroidism and spleen-kidney yang deficiency, and can promote the reduction and disconti-nuation of thyroid hormone preparations. The mechanism may be related to the regulation of cAMP/cGMP balance, the regulation of hypothalamic-pituitary-thyroid metabolic axis and the reduction of immune inflammation.
