BACKGROUND Transcatheter arterial embolization(TAE)has been widely used as an effective and a safe treatment method and was often used as an alternative to the surgical management,but there are limited studies on the efficacy and the safety for patients undergoing their secondary postpartum hemorrhage(PPH).AIM To evaluate the usefulness of TAE for secondary PPH focusing on the angiographic *** We conducted a research from January 2008 to July 2022 on all 83 patients(mean:32 years,range:24-43 years)presented with secondary PPH and they were treated with TAE in two university *** medical records and angiography were retrospective reviewed in order to evaluate the patients’characteristics,delivery details,clinical status and peri-embolization management,angiography and embolization details,technical/clinical success and *** group with active bleeding sign and the group without it were also compared and *** On angiography,46(55.4%)patients showed active bleeding signs such as contrast extravasation(n=37)or pseudoaneurysm(n=8)or both(n=1),and 37(44.6%)patients showed non-active bleeding signs such as only spastic uterine artery(n=2)or hyperemia(n=35).In the active bleeding sign group there were more multiparous patients,low platelet count,prothrombin time prolongation,and high transfusion *** technical success rates were 97.8%(45/46)in active bleeding sign group and 91.9%(34/37)in non-active bleeding sign group,and the overall clinical success rates were 95.7%(44/46)and 97.3%(36/37).An uterine rupture with peritonitis and abscess formation occurred to one patient after the embolization,therefore hysterostomy and retained placenta removal were performed which was a major *** TAE is an effective and a safe treatment method for controlling secondary PPH regardless of angiographic findings.

Korean oriental medicine prescription is widely used for the treatment of gouty diseases. In the present study, we investigated anti-inflammatory effects of modified Korean herbal formulation, mixed extract of medicinal herbs(MEMH), and its modulatory effects on inflammatory mediators associated with gouty arthritis. Both in vitro and in vivo studies were carried out to assess the anti-inflammatory efficacy of MEMH on monosodium urate(MSU) crystals-induced gouty inflammation. MSU crystals stimulated human chondrosarcoma cell line, SW1353, and human primary chondrocytes were treated with MEMH in vitro. The expression levels of pro-inflammatory mediators and metalloproteases were analyzed. The effect of MEMH on NFκB signaling pathway in SW1353 cells was examined. Effect of MEMH on the mR NA expression level of pro-inflammatory mediators and chemotactic factor from human monocytic cell line, THP-1, was also analyzed. The probable role of MEMH in the differentiation process of osteoblast like cells, SaO S-2, after MSU treatment was also observed. To investigate the effects of MEMH in vivo, MSU crystals-induced ankle arthritic model was established. Histopathological changes in affected joints and plasma levels of pro-inflammatory mediators(IL-1β and TNFα) were recorded. MEMH inhibited NFκB signaling pathway and COX-2 protein expression in chondrocytes. MSU-induced mR NA expressions of pro-inflammatory mediators and chemotactic cytokines were suppressed by MEMH. In MSU crystals-induced ankle arthritic mouse model, administration of MEMH relieved inflammatory symptoms and decreased the plasma levels of IL-1β and TNFα. The results indicated that MEMH can effectively inhibit the expression of inflammatory mediators in gouty arthritis, demonstrating its potential for treating gouty arthritis.

Benign neoplasia of the duodenum are very rare. Moreover, duodenal tubulovillous adenomas are more uncommon lesions. The microscopic structure of tubulovillous adenoma has frond-like projection of mucosa with branching papillary structure and generally upward growth into the lumen. We describe a 72-year-old man who showed aduodenal tubulovillous adenoma with unusual inverted cystic growth pattern. Interestingly, this tubulovillous adenomatous lesion was interrupted by gastric metaplasia in the deep portion of the cyst and was closely surrounded by Brunner’s glands. Although histogenesis of gastric metaplasia of duodenum is not fully understood, Brunner’s glands has been suggested as a precursor for gastric metaplasia. Therefore, these findings argued that this adenoma arises from Brunner’s glands through gastric metaplasia. This is the first case of inverted cystic tubulovillous adenoma involving Brunner’s glands of duodenum with gastric metaplasia.

As a new class of two-dimensional materials, two-dimensional (2D) heterostructures constructed from metal chalcogenides (MCs) have been gaining tremendous attention due to their unprecedented physical and chemical phenomena, mainly originated from their distinct structural features such as composition, architecture type, spatial arrangement of each component, crystal structure, exposed facet and interface, dimensionality in their heterostructures. Towards the realization of practical applications, synthetic approaches need a rational design with a variety of architecture types including laterally-combined, vertically-aligned, and conformally-coated 2D MC heterostructures. Among various synthetic routes, solution-based synthesis is thought of as an alternative to fabrication through high-cost setups since it can control those structural features in a cheap fashion. This review presents recent progress on solution-based synthesis to produce various 2D MC heterostructures with a focus on the synthetic fundamentals in terms of thermodynamic and kinetic aspects related to the growth mechanism. Four different synthetic approaches are reviewed: seeded growth, cation exchange reaction, colloidal atomic layer deposition, direct synthesis including one-step process and modified electrochemical method. We also provide some representative applications of 2D MC heterostructures and their hybrid composites in various fields including optoelectronics, thermoelectrics, catalysis, and battery. Finally, we offer an insight into challenges and future directions in a synthetic improvement of 2D MC heterostructures.

On the setting of the unit ball U the author considers Toeplitz operators on Bergman *** Bergman space Bp(U) (1≤ p < ∞) is the closed subspace of the usual Lebesgue space LP(U) consisting of holomorphic functions. For a function β ∈ L2(U), the Toeplitz operator Tβ with symbol β is defined by Tβf = (βf) for function f ∈ B2(U). Here is the Bergman projection from L2(U) onto B2(U). Two bounded linear operators S, T on the Hilbert H are said to be essentially commuting on H if the commutator ST - TS is compact on H. In this paper, a criterion of essentially Toeplitz operators with the vanishing property is obtained.

AIM： To investigate the efficacy of combined topical 0.05% cyclosporine A（CsA; Restasis~？, Allergan pharmaceuticals, USA） and 0.1% sodium hyaluronate treatment in dry eyes with meibomian gland dysfunction（MGD）.METHODS： In a retrospective analysis, 53 patients（106 eyes） with MGD were enrolled and performed lid warm massage for 10 min daily and be instilled preservative free sodium hyaluronate 0.1% eye drops 4 times daily. Patients were divided into subjects treated with topical 0.05% CsA and preservative free sodium hyaluronate vehicle（experimental group, n=74 eyes） and subjects treated with the preservative free sodium hyaluronate vehicle（control group, n=32 eyes）. They were evaluated at baseline and 1, 2, and 3 mo for subjective symptoms and objective signs including tear film break-up time（t BUT）, Schirmer test, corneal staining（CS） score, lid margin telangiectasia（LMT）, meibomian gland secretion（MGS）, and conjunctival injection（CI）.RESULTS： In the short-term treatment, the experimental group showed a statistically significant improvement in the ocular surface disease index（OSDI; P〈0.001）, tBUT（P=0.004）, Schirmer test score（P=0.008） and LMT（P=0.021） by repeated measure ANOVA. Additionally, mean changes from baseline in OSDI（P〈0.001）, tBUT（P=0.001）, Schirmer test score（P=0.029）, CS score（P=0.047）, LMT（P=0.002）, CI（P=0.030） were improved better in the experimental group than in the control group at 3 mo. However, there was no significant difference between the two groups in MGS（P=0.67）.CONCLUSION： In dry eyes with MGD, 0.05% CsA improves the tear film stability as well as subjective ocular discomfort, and is effective in controlling lid margin inflammation.
