Panax ginseng is a medicinal herb that is used worldwide. Its medicinal effects are primarily attributable to ginsenosides located in the root, leaf, seed, and flower. The flower buds of Panax ginseng (FBPG) are rich in various bioactive ginsenosides, which exert immunomodulatory and anti-inflammatory activities. The aim of the present study was to assess the effect of 18 ginsenosides isolated from steamed FBPG on the transcriptional activity of NF-kappaB and the expression of tumor necrosis factor-alpha (TNF-alpha)-stimulated target genes in liver-derived cell lines. Noticeably, the ginsenosides Rk3 and Rs4 exerted the strongest activity, inhibiting NF-kappaB in a dose-dependent manner. SF and Rg6 also showed moderately inhibitory effects. Furthermore, these four compounds inhibited the TNF-alpha-induced expression of IL8, CXCL1, iNOS, and ICAM1 genes. Consequently, ginsenosides purified from steamed FBPG have therapeutic potential in TNF-alpha-mediated diseases such as chronic hepatic inflammation.

PURPOSE: The Ministry of Health and Welfare recently designated 35 major trauma-specified centers (MTSC). The purpose of this study is to determine changes in patient flow and designated hospitals, and to describe the role of the emergency medical information center (EMIC) in a regional trauma care system. METHODS: Data of trauma patient inter-facility transfer arrangement by one EMIC were reviewed for 2 months before and after the designation of MTSC. The data included success or failure rates of the arrangement, time used for arrangement, and inquiring and accepting facility. RESULTS: At pre- and post-designation study period, there were 540 and 433 trauma patient inter-facility transfers arranged by EMIC, respectively. The median time used for arrangement decreased from 9.3 to 7.7 minutes (P = 0.007). Arrangement failure rate was 3.5% and 2.5%, respectively, with no significant interval change (P = 0.377). The percentage of inquiring MTSC decreased from 49.1 to 36.9% (P < 0.001). The percentage of accepting MTSC increased from 20.2 to 37.4% (P < 0.001). CONCLUSION: With the designation of MTSC, EMIC could arrange inter-facility transfers more quickly. The hospitals wanted more trauma patients after the designation. There would be a concentration of trauma patients to MTSCs in our region. Further studies are needed for scientific evidence on patient outcome.

Background/Aims:
Hypercontractile esophagus (HE) is a heterogeneous disorder with variable clinical presentations and a natural course, leading to management challenges. This study aims to investigate the characteristics of HE and evaluate its treatment outcomes.
Methods:
Four Korean referral centers recruited subjects with at least 1 hypercontractile swallow (distal contraction integral > 8000 mmHg·s·cm) in this retrospective observational study. Subjects were classified according to the Chicago classification version 2.0 (CC v2.0), CC v3.0, and CC v4.0. criteria. The clinical and manometric features were also investigated. The treatment modalities and outcomes of subjects with CC v4.0 were evaluated.
Results:
In total, 59 subjects with at least 1 hypercontractile swallow were analyzed. Among them, 30 (50.8%) had increased integrated relaxation pressure values without meeting the criteria for achalasia. Among the remaining 29 patients, 6 (20.7%) had only 1 hypercontractile swallowing symptom (CC v2.0) and 23 (79.3%) met both the CC v3.0 and v4.0 criteria for HE. Dysphagia (91.3%) was the most prevalent symptom, followed by chest pain (56.5%), regurgitation (52.2%), globus (34.8%), heartburn (21.7%), and belching (8.7%). Twenty (87.0%) patients received medical treatment, and 8 (47.1%) and 5 (29.4%) showed moderate and significant improvements, respectively. Proton pump inhibitors were the most common option (n = 15, 65.2%), followed by calcium channel blockers (n = 6, 26.1%). One patient received peroral endoscopic myotomy and showed significant symptom improvement.
Conclusions
Sixty-one percent of patients who meet the diagnostic criteria for the high-resolution manometry are diagnosed with symptomatic HE based CC v4.0. Chest pain and regurgitation were also observed in over half of them. The overall medical treatment efficacy was moderate.

A 28-year-old man was admitted due to abdominal pain and nausea. The patient had been diagnosed with peritoneal tuberculosis and was being treated with anti-tuberculous drugs. After 7 months of therapy, he developed abdominal pain, nausea, and melena. Gastrofiberscopy showed a duodenal ulcer and fistular opening. Abdominal CT revealed an aneurysm of the replaced hepatic artery due to abdominal tuberculous lymphadenopathy. After embolization of the aneurysm, his symptoms improved. Although mycotic aneurysm occurs rarely as a complication of tuberculous lymphadenopathy, it should be diagnosed as early as possible because of the high rate of rupture and associated high mortality.

A new blood bank system was established in our trauma bay, which allowed immediate utilization of uncross-matched type O packed red blood cells (UORBCs). We investigated the efficacy of UORBC compared to that of the ABO type-specific packed red blood cells (ABO RBCs) from before the bank was installed. From March 2016 to February 2017, data from trauma patients who received UORBCs in the trauma bay were compared with those of trauma patients who received ABO RBCs from January 2013 to December 2015. Propensity matching was used to overcome retrospective bias. The primary outcome was 24-hour mortality, while the secondary outcomes were in-hospital mortality and intensive care unit (ICU) length of stay (LOS). Data from 252 patients were reviewed and UORBCs were administered to 64 patients. The time to transfusion from emergency room admission was shorter in the UORBC group (11 [7–16] minutes vs. 44 [29–72] minutes, P < 0.001). After propensity matching, 47 patients were included in each group. The 24-hour mortality (4 [8.5%] vs. 9 [13.8%], P = 0.135), in-hospital mortality (14 [29.8%] vs. 18 [38.3%], P = 0.384), and ICU LOS (9 [4–19] days vs. 5 [0–19] days, P = 0.155) did not differ significantly between groups. The utilization of UORBCs resulted in a faster transfusion but did not significantly improve the clinical outcomes in traumatic shock patients in this study. However, the tendency for lower mortality in the UORBC group suggested the need for a large study.

Objectives:
The incidence of adenocarcinomas of the esophagogastric junction (EGJ) and cardia has been gradually increasing in the East. Cancers of the EGJ and gastric cardia have poor prognoses. This study aimed to investigate lymph node metastasis (LNM) rates, their predictive factors, and determine the long-term outcomes of patients with Siewert type II/III early gastric cancer (EGC).
Methods:
Between January 2014 and June 2022, a total of 573 patients with gastric cancer, including 130 with Siewert type II/III EGC, underwent total gastrectomies at the Kosin University Gospel Hospital. Factors associated with LNM were analyzed using a logistic regression model.
Results:
Of the 130 patients with Siewert type II/III EGC, 10 (7.7%) demonstrated LNM (LNM-positive group). Macroscopically elevated lesions (I+IIa) (60.0% vs. 16.7%; p=0.009) and lymphovascular invasion (70.0% vs. 5.8%; p<0.001) were more common and the depth of invasion was deeper (p=0.003) in the LNM-positive patients than in the LNMnegative group. Multivariate analysis showed that macroscopically elevated lesions (odds ratio [OR], 19.48; 95% confidence interval [CI], 1.93–197.11; p=0.012) and lymphovascular invasion (OR, 52.63; 95% CI, 5.26–526.51; p=0.001) were associated with LNM. Kaplan–Meier analysis revealed that the 5-year overall and disease-specific survival rates of patients with Siewert type II/III EGC were 90.0% and 98.9%, respectively. During a median follow-up period of 49 months (range, 12–122 months), one patient (0.8%) died owing to gastric cancer recurrence.
Conclusions
Patients with Siewert type II/III EGC showed favorable long-term outcomes. Macroscopically elevated lesions and lymphovascular invasion are associated with LNM.
