Irreversible electroporation (IRE) is a novel form of soft tissue ablation therapy that uses highcurrent electrical pulses to induce the formation of pores in the cell membrane, leading to cell death. Although outcome data for the ablation of hepatocellular carcinoma (HCC) by IRE are limited, early results are encouraging and may suggest equivalency to the outcomes achieved by thermal ablation methods such as radiofrequency ablation (RFA) and microwave ablation (MWA). However, IRE can be a challenging and very time-consuming procedure compared to RFA and MWA. In this review article, we not only evaluate the efficacy and safety of IRE for the treatment of HCC, but also discuss imaging guidance, ablation monitoring, and endpoint assessment, with a particular focus on ultrasonography.Purpose In a minority of cases, the transfemoral approach cannot be performed due to unfavorable anatomical barriers. Linsitinib In such cases, direct common carotid artery puncture (DCCAP) is an important alternative for rescue mechanical thrombectomy. The purpose of this study was to evaluate the efficacy and safety of DCCAP in patients with an unaccessible femoral route for mechanical thrombectomy. Materials and methods This is a retrospective study using data in the Turkish Interventional Neurology Database recorded between January 2015 and April 2019. Twenty-five acute stroke patients treated with DCCAP were analyzed in this study. Among 25 cases with carotid puncture, 4 cases were excluded due to an aborted thrombectomy attempt resulting from unsuccessful sheath placement. Results Patients had a mean age of 69±12 years. The average National Institutes of Health Stroke Scale score was 16±4. Successful revascularization (modified Thrombolysis In Cerebral Infarction 2b-3) rate was 86% (18/21), and 90-day good functional outcome rate (modified Rankin Scale 0-2) was 38% (8/21). Conclusion DCCAP is a rescue alternative for patients with unfavorable access via the transfemoral route. Timely switching to DCCAP is crucial in these cases.Congenital cataract is a common eye disease that seriously affects the visual development of infants and children. Nearly 30% of cases have cataract-linked, inherited mutations. With the development of molecular genetics, especially gentechnik, more and more genes, such as crystallin genes, membrane protein genes, transcription factors and cytoskeletal protein genes, have been confirmed to be associated with the onset of congenital cataract. There have been many studies on crystallin genes, but studies on the pathogenesis of membrane protein genes have gradually been emphasized as well in recent years. Furthermore, major intrinsic protein (MIP) genes belong to membrane protein genes, and the MIP translated by them accounts for about 50% of the total cell membrane proteins.It has been found that more than twenty mutations in MIP genes participate in the development of congenital cataract. How do these mutations further affect the cellular function and eventually lead to cataract? The recent progression about inherited congenital cataract related with MIP genes at the levels of genes and proteins is summarized in this review.

Methods Experiment research. A rapid and substantial elevation of intraocular pressure was performed to establish an acute hypertensive glaucoma model, and retinal thickness was assessed at 1, 3, 5, and 7 days. The mice were then randomly divided into three groups normal control group, hypertension group, and baicalin (50 mg/kg) for hypertension group. The effects of baicalin on the RGCs were evaluated by retrograde transporting of Fluoro-Gold. The mRNA levels of tumor necrosis factor-α, interleukine-1β (IL-1β), and inducible nitric oxide synthase were detected by real-time PCR, and the protein levels were measured by Western blot in the retina tissue of acute hypertensive glaucoma model. Purified primary RGC survival under OGD/R stress was measured by flow cytometry, which wad from 51.53%±1.36% to 69.37%±7.09% and 66.23%±4.25% with 5.0, 10.0 μmol/L baicalin administration (t=5.50, 4.53; both P less then 0.01). BV2 under OGD/R stress did extra damage to RGCs, and baicalin could reverse the damages and increase the survival from 69.37%±7.09% to 73.00%±5.20% (t=2.82, P=0.048) by reducing the release of IL-1β [(39.97±8.76) pg/ml vs. (61.33±5.78) pg/ml, t=4.19, P=0.010]. Conclusion Baicalin could alleviate retina tissue injury directly and promote the survival of RGCs by downregulating the expression of inflammatory cytokines and protecting RGCs from ischemia reperfusion injury.

Data of 48 patients (48 eyes) with ocular injuries caused by chestnut burrs hospitalized in Qingdao Eye Hospital were collected from January 2013 to March 2019. All patients were followed up for at least 3 months. The time of seeking medical advice, lesion region, and characteristics and treatment methods were analyzed. Results There were 48 patients, including 33 males and 15 females, aged 19 to 74 years [mean, (56±10) years]. The time of injury was late September (25 cases) and early October (23 cases). The shortest time to visit our hospital was 3 hours after injury, and the longest was 8 months after injury. There were 13 cases (27.1%, 13/48) with corneal and/or scleral foreign bodies. All patients were treated with corneal or scleral foreign body extraction. Twenty-four patients (50.0%, 24/48) developed fungal keratitis. Among them, 18 patients had a corneal un bodies should be removed as soon as possible. In the case of fungal keratitis, a drug or surgical intervention should be carried out as early as possible. Necrotizing scleritis is often induced by long-term foreign body retention. Scleral incision and exploration is an effective form of treatment. (Chin J Ophthalmol, 2020, 56 370-375).
