Objectives:To access the effectiveness of our modified right-ventricular overhauling procedure on tricuspid valve(TV)growth in patients with pulmonary atresia with intact ventricular septum(PAIVS).Methods:We retrospectively reviewed 21 patients with PAIVS who underwent modified right ventricular overhauling(mRVoh)between 2008 and 2019 at two *** mRVoh consisted of wide resection of hypertrophied infundibular and trabecular muscle,peeling off fibrotic endocardial tissue in the right ventricle(RV)cavity,surgical pulmonary valvotomy,and Blalock-Taussig shunt or banding of ductus arteriosus under cardiopulmonary *** TV annulus sizes were measured and analyzed using echocardiography before and after ***:No mortalities were observed during a median follow-up of 3 years(interquartile range:1.3–4.7 years)of follow-up were *** was performed at a median age of 163.5 days(range:21–560 days),including seven neonates and two infants(<60 days).During follow-up,the median TV annular z-score increased significantly from−2.24 to−1.15 before and after mRVoh(p=0.004).In ten patients with a prior history of percutaneous interventions for RV outflow tract(RVOT)widening at least 6 months before mRVoh,the TV annular z-score significantly changed during the period after mRVoh(−2.03 to−1.61,p=0.028)compared with the period before mRVoh(−2.51→–2.03,p=0.575)after percutaneous intervention ***:mRVoh in PAIVS patients was positively associated with TV annular growth,and it was more effective than percutaneous RVOT widening interventions without mRVoh.

Transmural penetration of sigmoid colon and rectum by retained surgical sponge after hysterectomy

引用

World Journal of Gastroenterology 2016年第10期22卷 3052-3055页

作者： Woo Young shin Chan Hyuk Im Sun Keun Choi yun-Mee Choe Kyung Rae Kim Department of Surgery Inha University HospitalInha University College of Medicine

Gossypiboma is a surgical sponge that is retained in the body after the operation. A 39-year-old female presented with vague lower abdominal pain, fever, and rectal discharge 15 mo after hysterectomy. The sponge remaining in the abdomen had no radiopaque marker. Therefore a series of radiographic evaluations was fruitless. The surgical sponge was found in the rectosigmoid colon on colonoscopy. The sponge penetrated the sigmoid colon and rectum transmurally, forming an opening on both sides. The patient underwent low anterior resection and was discharged without postoperative complications.

Anti-inflammatory and anti-apoptotic effects of rosuvastatin by regulation of oxidative stress in a dextran sulfate sodium-induced colitis model

引用

World Journal of Gastroenterology 2017年第25期23卷 4559-4568页

作者： Seung Kak shin jae Hee Cho Eui Joo Kim Eun-Kyung Kim Dong Kyun Park Kwang An Kwon Jun-Won Chung Kyoung Oh Kim Yoon jae Kim Division of Gastroenterology and Hepatology Department of Internal Medicine Gachon University Gil Medical Center

To evaluate the anti-inflammatory and anti-apoptotic effects of rosuvastatin by regulation of oxidative stress in a dextran sulfate sodium (DSS)-induced colitis model. METHODSAn acute colitis mouse model was induced by oral administration of 5% DSS in the drinking water for 7 d. In the treated group, rosuvastatin (0.3 mg/kg per day) was administered orally before and after DSS administration for 21 d. On day 21, mice were sacrificed and the colons were removed for macroscopic examination, histology, and Western blot analysis. In the in vitro study, IEC-6 cells were stimulated with 50 ng/mL tumor necrosis factor (TNF)-α and then treated with or without rosuvastatin (2 μmol/L). The levels of reactive oxygen species (ROS), inflammatory mediators, and apoptotic markers were measured. RESULTSIn DSS-induced colitis mice, rosuvastatin treatment significantly reduced the disease activity index and histological damage score compared to untreated mice (P < 0.05). Rosuvastatin also attenuated the DSS-induced increase of 8-hydroxy-2’-deoxyguanosine and NADPH oxidase-1 expression in colon tissue. Multiplex ELISA analysis revealed that rosuvastatin treatment reduced the DSS-induced increase of serum IL-2, IL-4, IL-5, IL-6, IL-12 and IL-17, and G-CSF levels. The increased levels of cleaved caspase-3, caspase-7, and poly (ADP-ribose) polymerase in the DSS group were attenuated by rosuvastatin treatment. In vitro, rosuvastatin significantly reduced the production of ROS, inflammatory mediators and apoptotic markers in TNF-α-treated IEC-6 cells (P < 0.05). CONCLUSIONRosuvastatin had the antioxidant, anti-inflammatory and anti-apoptotic effects in DSS-induced colitis model. Therefore, it might be a candidate anti-inflammatory drug in patients with inflammatory bowel disease.

Elevating the charge cut-off voltage beyond traditional 4.2 V is a commonly accepted technology to increase the energy density of Li-ion batteries(LIBs) but the risk of Li-dendrites and fire hazard increases as well. The use of ambi-functional additive, which forms stable solid electrolyte interphase(SEI) simultaneously at both cathode and anode, is a key to enabling a dendrites-free and well-working high-voltage LIB. Herein, a novel ambi-functional additive, pentaerythritol disulfate(PEDS), at 1 wt% without any other additive is demonstrated. We show the feasibility and high impacts of PEDS in forming lithium sulfateincorporated robust SEI layers at NCM523 cathode and graphite anode in 1 Ah-level pouch cell under4.4 V, 25 °C and 0.1 C rate, which mitigates the high-voltage instability, metal-dissolution and cracks on NCM523 particles, and prevents Li-dendrites at graphite anode. Improved capacity retention of 83%after 300 cycles is thereby achieved, with respect to 69% with base electrolyte, offering a promising path toward the design of practical high-energy LIBs.

CXCR1 is a G-protein coupled receptor, transducing signals from chemokines, in particular the interleukin-8 （1L8） molecules. This study combines homology modeling and molecular dynamics simulation methods to study the structure of CXCRI-IL8 complex. By using CXCR4-vMIP-II crystallography structure as the homologous template, CXCRI-IL8 complex structure was constructed, and then refined using all-atom molecular dynamics simulations. Through extensive simulations, CXCRI-IL8 binding poses were investigated in detail. Furthermore, the role of the N-terminal of CXCR1 receptor was studied by comparing four complex models differing in the N-terminal sequences. The results indicate that the receptor N-terminal affects the binding of IL8 significantly. With a shorter N-terminal domain, the binding of IL8 to CXCR1 becomes unstable. The homology modeling and simulations also reveal the key receptor-ligand residues involved in the electrostatic interactions known to be vital for complex formation.
