Objective To compare the clinical efficacy and complications between endovascular microwave ablation (EMA) combined with foam sclerotherapy and radiofrequency ablation (RFA) combined with foam sclerotherapy in patients with varicose veins of lower extremity. Methods A total of 106 patients with varicose veins of lower extremity were included in the retrospective study.Among them, 54 patients (observation group) were treated with EMA combined with foam sclerotherapy, and 52 patients (control group) were treated with RFA combined with foam sclerotherapy.The related clinical indexes and complications between the two groups were compared. Results The observation group had a shorter procedure time than the control group (34.92±2.35 minutes vs 46.33±2.71 minutes, P＜0.05), and no significant differences were observed in the other procedure parameters.The hospitalization cost was (21063.74±850.47) yuan for the observation group and (23312.40±1035.86) yuan for the control group, and the hospitalization cost of the observation group was lower(P＜0.05).No significant differences were found in the total effective rate,total satisfaction and complication rate between the two groups.Comparison of venous clinical severity score (VCSS) and Aberdeen varicose vein questionnaire (AVVQ) scores before and one year after operation between the two groups showed no statistical differences (P＞0.05). While the VCSS and AVVQ scores of the patients showed a significant downward trend one year after operation (P＜0.05). Conclusions Microwave ablation is an effective treatment for varicose veins in the lower extremity, which has the same good short-term effect as radiofrequency ablation. Microwave ablation requires a shorter operation time and less cost.

Objective To make rational use of teicoplanin and better management of patients treated with teicoplanin. Methods Nine clinical issues related to the treatment of teicoplanin in Clinical practice guidelines for therapeutic drug monitoring of teicoplanin: a consensus review by the Japanese Society of Chemotherapy and the Japanese Society of Therapeutic Drug Monitoring (Japan, 2022) were interpreted from the perspective of pharmacy. Results The guidelines indicated that the area under drug-time curve/minimum inhibitory concentration was the key pharmacokinetic/pharmacodynamic parameters of teicoplanin.The purpose of therapeutic drug monitoring (TDM) of teicoplanin is to specify the target trough concentration (C_min), which guidelines recommend for severe or complex methicillin-resistant Staphylococcus aureus (MRSA) infection is 20-40 mg/L.The target C_min for uncomplicated MRSA infection with normal or mildly impaired renal function is 15-30 mg/L.For severe and/or complex MRSA infections, such as infective endocarditis and osteomyelitis, the C_min of teicoplanin was 20-40 mg/L. Conclusions The guidelines are aimed at the determination of target C_min of teicoplanin in patients with different pathological conditions, and provide reference for individual drug administration and teicoplanin TDM in clinical treatment.

分泌性中耳炎（SOM）的临床特征表现为听力下降和中耳积液,与中耳化脓性炎症常伴随耳部急性感染不同,SOM常伴随耳部闷胀、轻微耳痛等,致使听力出现障碍。SOM发病机制较为复杂,可能与感染、免疫、咽鼓管功能障碍等多种因素相关,治疗方法也因此呈现出多样化的特点。本文就SOM的病因病机及其治疗方式展开综述,以期为临床及早诊断和治疗SOM提供理论依据。

The clinical characteristics of secretory otitis media（SOM）are hearing loss and effusion in the middle ear．Different from acute ear infection of suppurative inflammation in the middle ear,SOM is often accompanied by ear tightness and mild earache,resulting in hearing impairment．The pathogenesis of SOM is complex,which may be related to infection,immunity,eustachian tube dysfunction and other factors．Therefore,the treatment methods are diversified．This paper reviews the etiology,pathogenesis and treatment of SOM,in order to provide theoretical basis for clinical early diagnosis and treatment of SOM.

目的 探析化疗联合调强放疗（IMRT）治疗老年（≥65岁）局部晚期鼻咽癌的临床效果。方法 选取2018年1月—2019年1月我院诊治的90例老年局部晚期鼻咽癌患者为研究对象,使用随机数表法将此90例患者分为观察组及对照组,各45例。观察组行IMRT,对照组行化疗联合IMRT,对比2组的效果。结果 2组的治疗总有效率均为100%,组间差异不显著（P<0.05）。观察组的生活质量改善率（93.33%）高于对照组（77.78%）（P<0.05）。对照组出现3~4级白细胞减少、呕吐、黏膜炎人数明显高于观察组（P<0.05）,两者其他毒副反应比较无显著差异（P>0.05）。观察组的1年总体生存率（91.11%）及3年总体生存率（75.56%）均高于对照组（86.67%、68.89%）（P<0.05）。结论 对于老年局部晚期鼻咽癌,化疗联合IMRT相比单纯IMRT降低了远期生存率,增加了毒副反应并影响疗后生活质量的改善,不宜常规应用,单纯IMRT可能是更合适的治疗选择。

Objective To explore the clinical effect of chemotherapy combined with intensity modulated radiation therapy（IMRT）in the treatment of elderly（≥65 years old）locally advanced nasopharyngeal carcinoma．Methods The study was carried out from January 2018 to January 2019．During this period,90 elderly patients with locally advanced nasopharyngeal carcinoma who were diagnosed and treated in our hospital were selected as the research objects．The random number table method was used to divide the 90 patients into observation groups,and the control group,each with 45 cases．The observation group was treated with IMRT,and the control group was treated with chemotherapy combined with IMRT．The effects of the two groups were compared．Results The total effective rate of the two groups was 100%,and there was no significant difference between the two groups（P<0.05）．The improvement rate of quality of life in the observation group（93.33%）was higher than that in the control group（77.78%,P<0.05）．The number of grade 3-4 leukopenia,vomiting and mucositis in the control group was significantly higher than that in the observation group（P<0.05）,and there was no significant difference in other side effects between the two groups（P>0.05）．The 1-year overall survival rate（91.11%）and 3-year overall survival rate（75.56%）of the observation group were higher than those of the control group（86.67%,68.89%,P<0.05）．Conclusions For locally advanced nasopharyngeal carcinoma in the elderly,chemotherapy combined with IMRT reduces the long-term survival rate,increases the toxic and side effects and affects the improvement of the quality of life after treatment．It is not suitable for routine application,and IMRT alone may be a more appropriate treatment choice.
