Bilateral total deafness after preparation of wild boar meat

IntroductionStreptococcus suis is responsible for a zoonosis for which Suidae (pigs and wild boars) constitute the reservoir, mainly in Asia, with a much lower prevalence in Europe. The predominant clinical manifestation is meningitis, possibly resulting in deafness.Case reportWe report the case of a woman hospitalised for meningitis complicated by labyrinthitis, occurring several hours after preparing a meal composed of wild boar meat. Despite the presence of intracochlear fibrosis, the patient was managed by sequential bilateral cochlear implants.DiscussionThe discussion presents a review of the international literature and describes the mechanisms responsible for hearing loss related to this rare zoonosis.     

实时剪切波弹性成像在拉米夫定治疗乙肝纤维化过程中的疗效评估作用

目的探讨实时剪切波弹性成像在评估拉米夫定治疗乙肝纤维化临床疗效中的作用。方法选取2017年1月～2018年1月我院收治的80例乙肝纤维化患者,根据随机数字法分为对照组和观察组,每组40例。对照组采用常规治疗,观察组在对照组的基础上给予拉米夫定进行治疗,治疗6个月。比较两组治疗前后肝功能、肝纤维化指标,利用实时剪切波弹性成像评估两组治疗前后肝脏弹性模量值及肝穿刺活检情况,并进行比较。结果两组治疗后AST、ALT、TBIL水平均明显低于治疗前,差异有统计学意义(P0.05);观察组治疗后AST、ALT、TBIL水平均明显低于对照组,差异有统计学意义(P0.05);两组治疗后HA、LN、PⅢPN-P、CL-Ⅳ水平及杨氏弹性模量值均显著低于治疗前,差异有统计学意义(P0.05);观察组治疗后HA、LN、PⅢPN-P、CL-Ⅳ水平及杨氏弹性模量值均显著低于对照组,差异有统计学意义(P0.05);与治疗前相比,两组治疗后肝穿刺活检结果均有好转,尤其是汇管区、肝小叶内炎症及肝纤维化改善明显。结论实时剪切波弹性成像作为肝脏硬度定量检测的无创性技术,可用于拉米夫定治疗乙肝纤维化临床疗效评估的重要方法。     

Comparison of inhaled nitric oxide with aerosolized prostacyclin or analogues for the postoperative management of pulmonary hypertension: a systematic review and meta-analysis

Abstract

Background: This study aims to compare the effectiveness of inhaled prostacyclin or its analoguesversus nitric oxide (NO) in treating pulmonary hypertension (PH) after cardiac or pulmonary surgery remains unclear.

Methods: PubMed, Cochrane, and Embase databases were searched for literature published prior to December 2019 using the following keywords: inhaled, nitric oxide, prostacyclin, iloprost, treprostinil, epoprostenol, Tyvaso, flolan, and pulmonary hypertension. Randomized controlled trials and multiple-armed prospective studies that evaluated inhaled NO versus prostacyclin (or analogues) in patients for perioperative and/or postoperative PH after either cardiac or pulmonary surgery were included. Retrospective studies, reviews, letters, comments, editorials, and case reports were excluded.

Results: Seven studies with a total of 195 patients were included. No difference in the improvement of mean pulmonary arterial pressure (pooled difference in mean change= ?0.10, 95% CI: ?3.98 to 3.78, p?=?.959) or pulmonary vascular resistance (pooled standardized difference in mean change= ?0.27, 95% CI: ?0.60 to 0.05, p?=?.099) were found between the two treatments. Similarly, no difference was found in other outcomes between the two treatments or subgroup analysis.

Conclusions: Inhaled prostacyclin (or analogues) was comparable to inhaled NO in treating PH after cardiac or pulmonary surgery.

• Key messages

• This study compared the efficacy of inhaled prostacyclin or its analogues versus inhaled NO to treat PH after surgery. The two types of agent exhibited similar efficacy in managing MPAP, PVR, heart rate, and cardiac output was observed.

• Inhaled prostacyclin may serve as an alternative treatment option for PH after cardiac or pulmonary surgery.

     

胸腔镜肺小结节切除术前微弹簧圈定位的临床应用研究

目的:研究孤立性肺结节(SPN)胸腔镜术前CT引导下双弹簧圈精准标记定位的应用价值。方法:回顾分析43例SPN胸腔镜术前定位病例资料，包括双弹簧圈组22例，Hook-wire定位组21例。统计双弹簧圈定位的术中、术后并发症，衔接期时间以及作楔形切除所用时间，并将两组结果进行对比分析。结果:两组病例定位均取得成功；双弹簧圈组的气胸发生率(9.0%)，肺出血发生率(9.0%)，胸痛发生率(9.0%)均低于Hook-wire组，其中肺出血发生率与Hook-wire组比较，差异有统计学意义(P＜0.01)；衔接时间双弹簧圈组（15.38±8.32）h长于Hook-wire组（4.21±3.29）h，差异有统计学意义（P＜0.05）；作楔形切除所用时间双弹簧圈组(21.01±7.14)min与Hook-wire组(18.22±5.18)min差异无统计学意义(P＞0.05)。结论:采用双微弹簧圈进行SPN胸腔镜手术前精准标记定位安全可靠、效果良好，与Hook-wire定位比较并发症发生率更低，并可获得更长的衔接期，具有较高的应用价值。     

呼吸专科护士慢性呼吸疾病管理现状调查

目的调查呼吸专科护士慢性呼吸疾病管理现状,为提高慢性呼吸疾病的管理水平提供参考。方法依据《中国成人慢性呼吸疾病患者护理管理指南》设计调查问卷,对重庆、四川、贵州、陕西、河北、湖北、海南7省市的205名呼吸专科护士进行问卷调查。结果呼吸专科护士慢性呼吸疾病管理总分为(140.72±23.90)分。慢性呼吸疾病管理得分最低的3个条目有评估工具应用、个性化管理计划的实施、慢阻肺随访的次数及指导哮喘患者使用峰流速仪;呼吸专科护士所在单位慢性呼吸疾病管理平台建设均低于50%。结论呼吸专科护士慢性呼吸疾病管理处于中等偏下水平,评估是慢性呼吸疾病管理的薄弱点。需加强呼吸专科护士专业能力培养,规范慢性呼吸疾病全程管理,强化医院平台建设等,提高慢性呼吸疾病的管理水平。     

Non alcoholic fatty liver disease and risk of incident diabetes in subjects who are not obese

Background and aims

It is not known whether non alcoholic fatty liver disease (NAFLD) is a risk factor for diabetes in non obese, non centrally-obese subjects. Our aim was to investigate relationships between fatty liver, insulin resistance and a biomarker score for liver fibrosis with incident diabetes at follow up, in subjects who were neither obese nor centrally-obese.

桑根酮C对博莱霉素诱导小鼠肺纤维化改善作用及机制研究

目的观察桑根酮C对博莱霉素诱导的小鼠肺纤维化的影响,并探讨其可能的作用机制。方法 C57BL/6小鼠随机分为4组,即假手术组、模型组和桑根酮C(100、50 mg/kg)组,每组20只。假手术组小鼠气管内注射生理盐水,模型组小鼠气管内注射博莱霉素诱导肺纤维化模型。术后第4天开始给药,连续给药28d后检测小鼠呼吸功能;检测肺内羟脯氨酸含量;HE染色观察肺内炎症表现;Masson染色观察肺内胶原活性;免疫组化法检测肺内转化生长因子-β1(TGF-β1)蛋白表达量;免疫蛋白印迹法检测肺内α平滑肌肌动蛋白(α-SMA)、核转录因子-κB p65(NF-κB p65)、磷酸化的核转录因子-κB p65(p-NF-κB p65)、Ⅰ型胶原和Ⅲ型胶原表达量。结果与模型组比较,桑根酮C能够改善经博莱霉素诱导形成肺纤维化后小鼠的呼吸功能,能够明显降低肺内羟脯氨酸含量,明显减轻肺内炎症和胶原沉积,肺内TGF-β1、α-SMA、NF-κBp65、p-NF-κBp65、Ⅰ型胶原和Ⅲ型胶原蛋白表达量明显降低。结论桑根酮C能够明显改善博莱霉素诱导小鼠肺纤维化,改善呼吸功能,其机制可能与抑制TGF-β1过表达和降低炎症转录因子NF-κB及磷酸化表达有关。     

经皮肺动脉瓣植入术在肺动脉瓣反流患者中的临床应用

经皮肺动脉瓣植入术(PPVI)在我国作为一种新兴的技术,开展相对较晚,但随着我国医疗水平的不断提高以及临床对于右心室流出道梗阻的先天性心脏病患者术后出现重度肺动脉瓣反流的不断重视,PPVI在我国得到了飞速发展。近十几年来,欧美国家已在临床成熟应用PPVI,相对于传统外科手术而言其具有微创、可重复性、术后疗效好等优点。现对PPVI在肺动脉瓣反流患者中的临床应用进行叙述。     

重型/危重型新型冠状病毒肺炎机械通气患者的肺康复策略

结合国内外中西医肺康复的研究成果,探讨重型/危重型新型冠状病毒肺炎机械通气患者的肺康复策略。机械通气是治疗重型/危重型肺炎必不可少的支持手段,但可能引起呼吸肌无力,导致痰液排泄障碍,进而影响预后。对于重型/危重型新型冠状病毒肺炎机械通气患者而言,及早采取必要的中西医肺康复干预措施意义重大,不仅有助于缓解呼吸困难症状,而且可缩短住院时间、改善预后。
