Dry eye disease is a common and frequently occurring ophthalmology with complex and diverse causes, and its incidence is on the upward trend. The pathogenesis of DED is still completely clear. However, the immune response based on inflammation has been recognized as the core basis of this disease. In this review, we will systematically review the previous research on the treatment of DED in immune inflammation, analyze the latest views and research hotspots, and provide reference for the prevention and treatment of DED.
Aim: To determine whether hysteroscopy (HSC) increases the risk of intraperitoneal dissemination in endometrial cancer patients. Methods: We conducted a comprehensive review of multiple databases. Quality assessments of eligible studies were performed using the Newcastle-Ottawa and Jadad scales. Positive peritoneal cytology (PPC) as the outcome of interest was compared between endometrial cancer patients with and without HSC. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated as a measure of effects. Results: Three case-control studies and eight retrospective cohort studies included 3364 patients, of whom 1116 underwent preoperative HSC, which resulted in a significantly higher PPC rate (OR, 1.82; 95% CI, 1.31-2.54; p = 0.0004). I 2 was 11%, and the heterogeneity was acceptable. The difference between the groups with stages I-II was statistically insignificant (OR, 1.50; 95% CI, 0.75-2.99; p = 0.25). When liquid was used as the uterine distension medium during HSC and the intrauterine pressure was controlled under 80 mmHg, the difference between the two groups was also insignificant (OR, 1.18; 95% CI, 0.50-2.79; p = 0.71). However, when the intrauterine pressure exceeded 80 mmHg, the difference between the two groups was statistically significant (OR, 2.18; 95% CI, 1.28-3.73; p = 0.004).
Conclusion:This meta-analysis indicates that preoperative HSC in patients with endometrial cancer may increase the risk of intraperitoneal dissemination of malignant cells, which may be associated with intrauterine pressure >80 mmHg but not with stages I-II. There is no reason to avoid HSC for the diagnosis of endometrial cancer, especially in early stages, but intrauterine pressure should possibly be controlled below 80 mmHg.
Pheochromocytomas are neuroendocrine tumors, and its cardiac involvement may include transient myocardial dysfunction, acute coronary syndrome (ACS), and even ventricular arrhythmias.A patient was referred for evaluation of stuttering chest pain, and his electrocardiogram showed T-wave inversion over leads V1 to V4. Coronary angiography showed 90% stenosis in the mid-left anterior descending coronary artery (LAD), which was stented. Five days later, the patient had ventricular tachycardia, and severe hypertension, remarkable blood pressure fluctuation between 224/76 and 70/50 mm Hg. The patient felt abdominal pain and his abdominal ultrasound showed suspicious right adrenal gland tumor. Enhanced computed tomography of adrenal gland conformed that there was a tumor in right adrenal gland accompanied by an upset level of aldosterone.The tumor was removed by laparoscope, and the pathological examination showed pheochromocytoma. After the surgery, the blood pressure turned normal gradually. There was no T-wave inversion in lead V1-V4. Our case illustrates a rare pheochromocytoma presentation with a VT and resembling ACS. In our case, the serious stenosis in the mid of LAD could be explained by worsen the clinical course of myocardial ischemia or severe coronary vasospasm by the excessive amounts of catecholamines released from the tumor. Coronary vasospasm was possible because he had no classic coronary risk factors (e.g. family history and smoking habit, essential hypertension, hyperglycemia and abnormal serum lipoprotein, high body mass index). Thus, pheochromocytoma was missed until he revealed the association of his symptoms with abdominalgia.As phaeochromocytomas that present with cardiovascular complications can be fatal, it is necessary to screen for the disease when patients present with symptoms indicating catecholamine excess.
Protective effects of liraglutide on H9C2 cells cultured using CoCl 2 and its mechanism of action were investigated. Hypoxia model was established using CoCl 2-treated H9C2 cells. With liraglutide as the treatment factor, apoptosis, changes in nitric oxide (NO) and reactive oxygen species (ROS) activity, mitochondrial membrane potential and change in cell autophagy level were detected via Hoechst staining, enzyme-linked immunosorbent assay (ELISA), polymerase chain reaction (PCR) and western blotting (WB), respectively. Liraglutide ameliorated the CoCl 2-induced decrease in H9C2 cell viability, the increases in cytotoxicity and percentage of apoptotic cells as well as oxidative stress in cells. Moreover, it stimulated the elevation of cell autophagy level. However, the protective effects of liraglutide on H9C2 cells were attenuated remarkably after adding the cell autophagy inhibitor. Liraglutide can ameliorate the CoCl 2-induced oxidative stress and apoptosis in H9C2 cells via regulating cell autophagy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
