Objective:To explore the clinical characteristics, treatment methods, and prognosis of refractory pharyngeal ulcers. Methods:A retrospective analysis was conducted on the clinical manifestations, laryngoscopic features, laboratory tests, histopathological examinations, and treatments of 78 patients diagnosed with refractory pharyngeal ulcers. Results:There was no significant difference in the proportion of males-to-females in benign lesions, while males were significantly more prevalent in cases of malignant lesions. Seven distinct pathological types of pharyngeal ulcers were identified, with the most common being simple inflammatory ulcers（18 cases）, followed by tuberculosis（16 cases）, fungi（15 cases）, lymphoma（14 cases）, squamous cell carcinoma（10 cases）, Behcet's disease（3 cases）, and myelosarcoma（2 cases）. Conclusion:The clinical manifestations and lesions associated with refractory pharyngeal ulcers are diverse. A clear diagnosis should be established based on a systematic and comprehensive medical history, specialized examinations, and additional tests to avoid misdiagnosis and mistreatment. Laryngoscopy and histopathological examinations are essential for identifying the type of lesion and guiding appropriate treatment.

OBJECTIVE To compare the efficacy and safety of new oral anticoagulants （NOACs） and warfarin in the treatment of left ventricular thrombus （LVT）， and to provide evidenced-based reference for rational drug use in clinic. METHODS Retrieved from PubMed， Cochrane Library， Embase， Ovid Medline， CNKI， Wanfang and VIP during the inceptions to March 2022， after screening the literature and extracting data， the quality of randomized controlled trials （RCTs） was evaluated by using bias risk evaluation tool recommended by Cochrane systematic evaluator manual. Newcastle Ottawa Scale was used to evaluate the quality of cohort studies， and RevMan 5.3 software was used for meta-analysis and bias risk analysis. RESULTS A total of 13 studies were included in the analysis， including 2 RCTs， 11 cohort studies and 2 261 patients； results of meta-analysis showed that there was no statistical significance in the incidence of complete LVT resolution [OR＝1.05， 95%CI（0.81，1.37）， P＝0.71]， the incidence of stroke/systemic embolism [OR＝0.89， 95%CI（0.67，1.18）， P＝0.42]， the incidence of massive haemorrhage [OR＝ 0.61， 95%CI（0.19，1.97）， P＝0.41]， the incidence of rehospitalization [OR＝0.84， 95%CI（0.49，1.46）， P＝0.54] or all-cause mortality [OR＝0.93， 95%CI（0.56，1.56）， P＝0.79] between 2 groups. The incidence of any bleeding event in trial group was significantly lower than that control group[OR＝ 025-80863493。0.65， 95%CI（0.45，0.93）， P＝0.02]. Subgroup analysis showed that complete LVT resolution of patients with follow-up ≤6 months in trial group was significantly higher than control group， and the incidence of any bleeding event was significantly lower in patients with follow-up ＞6 months and in the European region than control group （P＜0.05）. There was no statistically significant difference in the rate of complete LVT resolution in patients with follow-up＞6 months， the incidence of any bleeding event in patients from Asia and America， or the incidence of any bleeding event in the two groups included in the RCT or the cohort study （P＞0.05）. The publication bias analysis showed that publication bias was less likely in the rate of complete LVT resolution but more likely in the incidence of any bleeding event. CONCLUSIONS NOACs can eliminate thrombus faster in the early stage， but with the prolongation of anticoagulation time， the efficacy of NOACs is comparable to warfarin， and the safety of NOACs in any bleeding event is better than warfarin.

Objective To summarize the clinical diagnosis and treatments of 55 reflux laryngitis (RL) pa-tients, and to study the relationship between gastroesophageal reflux disease (GERD) and RL. Methods The pa-tients went through the following diagnostic process consisting of the collection of medical history, laryngoscopy, gastroscope, X-ray barium meal examination, vocal evaluation, therapy of anti-acid and anti-reflux. Results The laryngeal manifestations of RL mainly consisted of laryngeal discomfort or foreign body sensation (89. 1%), chronic cough (36.4 % ), hoarseness (20 % ), laryngeal pain (18. 2 %), even severe aspiration or laryngismus (10.9%) and so on. With the laryngoscopy we could see congestion in arytenoids area (67.3%), swelling or pachynsis of a mucosal fold in interarytenoid area (43.6%), edema of true or false vocal cord(40%), a little dropsy staying in piriform sinus (32.70% ), contact ulcer or granuloma on posterior extremity of a vocal cord (20 % ), artificial sulcus under vocal cords (16.4 %). RL patients might have mild voice disorder, among whom 65.5 percent displayed ten-sion dysphonia. Fundamental frequency (F0), jitter, shimmer and normalized noise energy (NNE) of RL patients increased. Compared with the controls, there were significant differences (P<0. 05) except for the F0 of female pa-tients. The manifestation and physical symptoms were improved or disappeared after the treatment with proton pump inhibitor (PPI). Conclusion RL is one of the important manifestations of GERD out of digestive tract. Typi-cal RL manifestation is mainly a pathological process in the postero-glottis. Clinically, PPI can be used as not only a treatment but also a tentative diagnosis of RL.
