목 적: 본 연구는 만성 스트레스로 인한 갱년기 우울증 모델에서 사물탕가향부자(SGH)의 항우울 효과를 검증하여 실험적 유의성을 확인하고자 시행되었다. 방 법: 난소적출 흰쥐에 4주간 만성 스트레스를 가하고 SGH(100 and 400 mg/kg/day)를 투여한 후 행동검사인 sucrose intake test(SIT), elevated plus maze(EPM), forced swimming test(FST) 및 Morris water maze test(MWMT) 등을 통한 우울행동 변화와 혈청 corticosterone(CORT), IL-$1{\beta}$ 및 IL-4 등의 변화를 측정하였고, 또한 뇌 내 hippocampus와 hypothalamus에서 5-HT의 변화를 측정하였다. 결 과: 1. SIT에서 SGH 400 mg/kg/day 투여군은 대조군에 비해서 자당 섭취가 유의하게 증가하였다(p<0.05). 2. EPM에서 SGH 400 mg/kg/day 투여군은 대조군에 비해서 open arms에 머무는 시간이 유의하게 증가하였고(p<0.01), open arms와 closed arms를 교차하는 횟수도 대조군에 비해서 유의하게 증가하였다(p<0.05). 3. FST에서 SGH 100 mg/kg/day, 400 mg/kg/day 투여군 모두 대조군에 비해서 immobility시간이 유의하게 줄어들었다(SGH 100 p<0.05, SGH 400 p<0.01). 4. MWMT에서 SGH 100 mg/kg/day, 400 mg/kg/day 투여군은 모두 대조군에 비해서 실험 4일째에서 acquisition trials 수행 시간이 유의하게 단축되었고(p<0.05), SGH 400 mg/kg/day 투여군은 대조군에 비해서 retention trials 수행 시간이 유의하게 증가하였다(p<0.05). 5. CORT와 IL-4 측정에서 대조군과 SGH 투여군 모두 유의한 변화가 없었고, IL-$1{\beta}$ 측정에서 대조군에서는 유의하게 증가하였지만 SGH 투여군에서는 대조군에 비해서 유의한 변화가 없었다. 6. Hippocampus에서의 5-HT 측정에서 SGH 400 mg/kg/day 투여군은 대조군에 비해서 유의하게 증가하였다(p<0.05). Hypothalamus에서의 5-HT수준은 SGH 투여군 모두 대조군에 비해서 유의하게 증가하였다(SGH 100 p<0.05, SGH 400 p<0.01). 결 론: 이상의 결과로 SGH는 만성 스트레스를 가한 난소적출 흰쥐에서 항우울 효과가 있음을 알 수 있었고, HPA axis, immune system 보다 5-HT system에 작용하는 것으로 사료된다. Objectives: The purpose of the present study is to investigate anti-depressive effects of Samul-tanggahyangbuja (SGH) on ovariectomized and chronic mild stress (CMS) induced rats. Methods: Ovariectomized rats were exposed to CMS for 4 weeks. Changes of depression behavior were tested by using sucrose intake test (SIT), elevated plus maze (EPM), forced swimming test (FST) and Morris water maze test (MWMT) in rats until being orally medicated with SGH (100 or 400 mg/kg/day). In addition, the serum levels of corticosterone (CORT), IL-4, IL-$1{\beta}$ and changes of 5-HT in the brain were measured. Results: 1. SGH 400 mg/kg treated group (SGH 400) significantly increased amount of sucrose intake compared with the control group (p<0.05). 2. SGH 100 mg/kg treated group (SGH 100) and SGH 400 significantly increased the time spent in the open arms of the EPM compared with the control group (p<0.01). SGH 400 also significantly increased the number of crossing of the open and closed arms compared with the control group (p<0.05). 3. SGH significantly shortened the immobility time in FST compared with the control group (SGH 100 p<0.05, SGH 400 p<0.01). 4. SGH significantly increased performance of acquisition trials compared with the control group (p<0.05, on day 4, 5 of SGH 100 and 400). SGH 400 also significantly increased performance of retention trials compared with the control group (p<0.05). 5. The serum levels of corticosterone and IL-4 were not significantly different among the groups. There were no changes on the serum levels of corticosterone, IL-$1{\beta}$ and IL-4 after administration with SGH. 6. SGH 400 significantly increased the level of 5-HT in the hippocampus compared with the control group (p<0.05). SGH significantly increased the levels of 5-HT in the hypothalamus compared with the control group (SGH 100 p<0.05, SGH 400 p<0.01). Conclusions: These results suggest that SGH has the anti-depressive effect on ovariectomized rat and affect 5-HT system rather than hypothalamic-pituitary-adrenal (HPA) axis and immune system.
Abstract Background Remimazolam is safe and effective for moderate sedation during flexible bronchoscopy, but its safety and efficacy during endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) remains undetermined. The REST trial (NCT06275594) will be a prospective randomized study of remimazolam in patients undergoing EBUS-TBNA with conscious sedation. The primary aim is to evaluate whether remimazolam is safe and effective for moderate sedation during EBUS-TBNA compared to real-world midazolam and on-label midazolam. Methods The REST trial will recruit 330 patients from four university hospitals with mediastinal lesions suspected of being lung cancer who are eligible for EBUS-TBNA under moderate sedation. The participants will be randomized into groups using remimazolam, real-world midazolam, and on-label midazolam (US prescribing information dosage) to perform EBUS-TBNA for procedural sedation. The primary endpoint will be procedural success using composite measures. Discussion The REST trial will prospectively evaluate the efficacy and safety of remimazolam during EBUS-TBNA under moderate sedation. It will provide information for optimizing sedation modalities and contribute to practical benefits in patients undergoing EBUS-TBNA. Trial registration ClinicalTrials.gov (NCT06275594). Prospectively registered on 15 February 2024.
Abstract The majority of acquired resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) is caused by secondary T790M mutation. We established gefitinib or erlotinib-resistant cells which acquired different proportions of T790M from PC-9 cells with activating EGFR mutation. Anti-cancer effects of EGFR modulation and strategies overcoming resistance were investigated. The amount of T790M and EGFR gene copy number were proportional to increase of resistance. BIBW-2992, an irreversible EGFR-TKI, could suppress the growth and survival of cells harboring lower level of T790M while it failed in cells with higher level of T790M although p-EGFR was completely down-regulated in both, suggesting blocking of phosphorylation of EGFR is not sufficient to inhibit these cells. However, EGFR siRNA treatment could inhibit cell growth regardless of T790M level and resistance showing that EGFR dependency would be persistent. 17-DMAG, a HSP90 inhibitor, also effectively controlled both resistant cells. Considering a report showing that a HSP90 inhibitor was not clinically effective possibly because of inadequate dose, the efficacy of low dose 17-DMAG was examined. Interestingly, we found that combined treatment of BIBW-2992 with low dose 17-DMAG was very effective even in cells with higher level of T790M although either of both showed no activity in single treatment suggesting it would be one of promising strategies with immediate clinical implications overcoming T790M-mediated resistance. Further investigations on exact mechanism should be pursued even though capability of HSP90 inhibitor to modulate NF-kB signaling can be one of possible explanations.

Objectives: In this research, the effect of samul-tanggahyangbuja on depression and learning in ovariectomized rats subjected to repetitive stress were assessed. Samul-tanggahyangbuja is the prescription consisting of Samul-tang and Cyperi Rhizoma. Methods: Ovariectomized rats were repeatedly stressed over a 2-week period. After being orally medicated with samul-tanggahyangbuja (100 or 400 mg/kg), rats performed the Morris water maze test and forced swimming test, and social exploration was assessed in a behavior test. As well, sucrose intake was measured and measurements of blood serum corticosterone and the change of interleukin-$1{\beta}$ (IL-$1{\beta}$) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in blood samples were made. Results: 1. In the Morris water maze test, rats medicated with 100 mg samul-tanggahyangbuja mastered the maze in a shorter time on the 4th day in comparison with the control group, while rats medicated with 400 mg samul-tanggahyangbuja mastered the maze more quickly (p<0.05 on the 3rd day ; p<0.01 on the 4th day, as compared to control). 2. Immobility time in the forced swimming test was significantly decreased in rats receiving 400 mg samul-tanggahyangbuja compared with the control group (p<0.05). 3. Sucrose intake and active social behavior of rats receiving 400 mg samul-tanggahyangbuja were markedly increased in comparison with the control group (p<0.01). 4. Blood serum corticosterone measurements revealed decreased blood serum corticosterone level after medicating with samul-tanggahyangbuja. But it was not statistically significant. 5. Treatment with either dose of samul-tanggahyangbuja significantly reduced IL-$1{\beta}$ and TNF-${\alpha}$ (p<0.05). Conclusions: These results suggest that samul-tanggahyangbuja possesses the anti-depressant and cognitive-enhancing activities related to menopause.
Very few studies have compared the effects and side effects of vancomycin and teicoplanin in patients with methicillin-resistant Staphylococcus aureus pneumonia. This study aimed to compare the efficacy and safety of vancomycin and teicoplanin in patients with methicillin-resistant Staphylococcus aureus pneumonia.This study examined 116 patients with methicillin-resistant Staphylococcus aureus pneumonia who met the inclusion criteria and were treated with either vancomycin (n = 54) or teicoplanin (n = 62). The primary (i.e., clinical failure during treatment) and secondary outcomes (i.e., mortality rates, discontinuation of study drugs due to treatment failure, side effects, and clinical cure) were evaluated.The vancomycin group presented lower clinical failure rates (25.9% vs. 61.3%, p < 0.001), discontinuation due to treatment failure (22.2% vs. 41.9%, p = 0.024), and mortality rates (3.7% vs 19.4%, p = 0.010). The Cox proportional hazard model revealed that teicoplanin was a significant clinical failure predictor compared with vancomycin (adjusted odds ratio, 2.198; 95% confidence interval 1.163-4.154). The rates of drug change due to side effects were higher in the vancomycin group than in the teicoplanin group (24.1% vs. 1.6%, p < 0.001).Vancomycin presented favorable treatment outcomes and more side effects compared with teicoplanin, which suggests that clinicians would need to consider the efficacy and potential side effects of these drugs before prescription.
Abstract Background A primary pulmonary invasive mucinous adenocarcinoma (IMA) is a rare subtype of invasive adenocarcinoma of the lung. The prognosis of advanced IMA depending on chemotherapy regimen has not been fully investigated. Here, we compared the clinical outcomes of patients with advanced IMA treated with different palliative chemotherapies that included novel therapeutics. Methods This single-center retrospective study included a total of 79 patients diagnosed with IMA and treated with palliative chemotherapy. The primary outcome was the comparison of overall survival according to palliative chemotherapy type. Risk factors associated with death were evaluated as a secondary outcome. Results The study cohort of 79 patients comprised 27 progressive or recurrent cases and 52 initial metastatic patients. Thirteen patients (16.5%) received targeted therapy and 18 cases (22.8%) received immunotherapy. When we compared the survival outcomes of the different treatment regimens, patients with IMA treated by immunotherapy (undefined vs. non-immunotherapy 17.0 months, p < 0.001) had better overall survival rates. However, there was no difference in the prognosis between the cases treated with a targeted therapy (35.6 vs. non-targeted therapy 17.0 months, p = 0.211). None of the conventional regimens produced a better outcome. By multivariable analysis, immunotherapy (HR 0.28; 95% CI 0.11–0.74; P = 0.008) was found to be an independent prognostic factor for death. Conclusions This study suggests that immunotherapy for patients with advanced IMA may provide favorable outcomes than other chemotherapy options.
Abstract Osimertinib, an irreversible, third-generation epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) that is initially developed to overcome EGFR T790M mutation, and use as standard therapy in patients with advanced non-small cell lung cancer (NSCLC) including EGFR activating mutations as well as EGFR T790M mutation. Despite remarkable efficacy of osimertinib, this therapy is limited by the emergence of acquired resistance, like other EGFR-TKIs. Since epidermal growth factor receptor mutation C797S was founded as the factor of acquired resistance to osimertinib, drug targeting the clinically relevant C797S mutation has not yet been developed. Here, we reported the discovery and preclinical efficacy of OBX02-011, fourth EGFR-TKI targeting overcome EGFR C797S mutation. Compared with the approved EGFR-TKIs, this agent showed potent anticancer effects and the inhibition of EGFR-related signaling in various models including EGFR C797S mutation. Additionally, we evaluated the efficacy of OBX02-011 in transgenic models (EGFRL858R+T790M+C797S), showing the enhanced survival, and inhibition of tumor growth and EGFR activity. Collectively, our data suggest that OBX02-011 may be promising new EGFR-TKI to overcome C797S-mediated resistance in NSCLC.
