阻塞性肺病呼气末肺残气量的CT评价

目的:探讨呼气末高分辨率CT(HRCT)对阻塞性肺病(OLD)患者的肺残气量的评估价值.方法:对有肺功能检测结果的13名健康志愿者与14例OLD患者行吸气与呼气末HRCT扫描,测量吸气与呼气状态下肺CT值,并目测呼气末HRCT扫描时肺残气量的范围.结果:所有的OLD与8名健康志愿者都有肺内空气残余,但OLD的范围明显增大.OLD患者在吸气与呼气时肺CT值变化及残气量分数与健康者明显不同,且与肺功能密切相关(P＜0.01).结论:呼气末HRCT可用于评估OLD患者肺残气量并可诊断这类疾病.肺CT值的测量与肺残气量的评估是两种有价值的分析方法.

Airway responses to antigen challenge in allergic rhinitis and allergic asthma

The density dependence of the maximum expiratory flow-volume curve, functional residual capacity (FRC), and specific airway conductance (SGaw) were determined before and during bronchial provocation with ragweed extract in 27 subjects with ragweed hypersensitivity and a history of either bronchial asthma (16 subjects) or allergic rhinitis (11 subjects). Mean baseline SGaw was significantly lower while mean volume of isoflow (Visov) and FrC were significantly higher in subjects with bronchial asthma. During antigen challenge, 10 of 16 subjects with bronchial asthma (63%) and five of 11 subjects with allergic rhinitis (45%) showed a greater than 35% decrease in SGaw ("reactors"): mean relative decreases in SGaw from baseline were 46% and 53%, respectively. The remaining subjects showed a less than 35% decrease in SGaw ("nonreactors") with mean relative decreases of 9% (allergic asthma) and 6% (allergic rhinitis). Mean Visov increased in all subjects with bronchial asthma and in eight of 11 subjects with allergic rhinitis. A significant increase in FRC (6%) was seen only in the "reactors" with bronchial asthma. Following antigen challenge, the beta adrenergic agonist, isoetharine, increased SGaw and decreased Visov. We conclude that in asymptomatic subjects with ragweed hypersensitivity, (1) central and peripheral airway function is more abnormal in subjects with bronchial asthma than in subjects with allergic rhinitis, (2) subjects of both groups show quantitatively and qualitatively comparable airway responses during antigen challenge with a decrease in SGaw or an increase in Visov, possibly representing increase in central and/or peripheral airflow resistance, respectively, (3) Visov may be a more sensitive indicator of airway response to antigen challenge than SGaw, and (4) the bronchodilator effects of a beta adrenergic agonist on antigen-induced bronchospasm are similar in both groups.

Intraductal shock-wave lithotripsy in complicated common bile duct stones

Summary Intracorporeal shockwave lithotripsy was performed in 36 patients with problematic common bile duct stones. All of the patients had undergone unsuccessful mechanical lithotripsy prior to this procedure. In 29 patients (80.6%), the stones were fragmented under cholangioscopic control and subsequently extracted with a Dormia basket. In seven patients, the procedure failed due to stone impaction or failure to intubate the common bile duct with a nasobiliary tube. No complications were observed. Cholangioscopically guided intracorporeal shockwave lithotripsy is a highly effective and safe procedure for the conservative treatment of complicated common bile duct stones.Abbreviations ESWL extracorporeal shock-wave lithotripsy - ISWL intracorporeal shock-wave lithotripsy Dedicated to Prof. Dr. med.

CT与MRI在诊断原发性肝癌介入术后病灶残留及复发中的应用

目的:对原发性肝癌患者介入术后接受CT、MRI诊断病灶残留及复发的临床价值进行系统研究与探讨。方法:选择本院2018年12月~2019年12月收治的90例行介入术原发性肝癌患者作为实验对象,数字奇偶法分组后探究每组诊断效果。对照组(45例)应用CT诊断;观察组(45例)应用MRI诊断。对比两组患者残留及复发病灶数量。结果:观察组残留及复发病灶数量为(66.44±3.75)个,较之于对照组,差异具有统计学研究意义(P<0.05)。结论:原发性肝癌患者接受介入手术治疗后,在诊断病灶残留与复发中,MRI诊断优势更明显。     

改质炉高温炉管运行损伤及剩余寿命分析

对高温运行70000h至90000h改质炉炉管进行试验研究及材料损伤分析,结果表明,炉管的材料性能已严重劣化（脆化）,炉管的内外壁已有微小裂纹萌生,测定了炉管材料在950℃、各种应力水平下的断裂时间,根据时间-温度参数L-M公式,推测炉管的剩余寿命为8510h。

残余胆囊结石6例诊治分析

目的 探讨残余胆囊结石的原因、诊治及预防。方法 回顾性分析绍兴市人民医院2016年10月至2019年12月收治的6例残余胆囊结石患者的临床诊治经过,分析其发生原因,探讨诊治方法及预防措施。结果 6例残余胆囊结石患者中,2例行腹部B超检查,其中1例证实为残余胆囊结石;所有患者行腹部增强CT检查,均证实为残余胆囊结石;3例患者行MRCP检查,其中2例确诊,1例未发现明显异常。6例残余胆囊结石患者中,2例行腹腔镜残余胆囊切除术,2例行腹腔镜中转开腹残余胆囊切除加胆总管探查T管引流术,1例行腹腔镜中转开腹残余胆囊切除术,1例拒绝手术治疗。5例手术患者均治愈出院,随访4～43个月,平均（19.8±14.7）个月,无结石复发情况。结论 增强CT在残余胆囊结石的诊断中具有重要价值。腹腔镜手术可作为首选的治疗方法。残余胆囊结石是多因素共同作用的结果,合理的手术方案,必要的手术技巧,良好的手术心态,及时中转开腹的意识对预防残余胆囊结石发生尤为重要。
