腹部手术对全身炎性反应综合征的影响

目的探讨腹部手术对全身炎性反应综合征(SIRS)的影响.方法我们分析了82例腹部术后在ICU留住患者,其中,男50例,女32例,平均在ICU留住8.8天.入ICU时APACHEII评分平均为10.8分.按临床资料分为SIRS组和非SIRS组,SIRS组中无明显感染者归为非感染性SIRS,有明确感染者分别诊断为全身性感染和感染性休克.结果按临床资料非SIRS组APACHEII评分平均为7.21分,SIRS组平均为13.34.SIRS组发生率为61.0%(50/82),SIRS组病死率为18%(9/50),而非SIRS组病死率为3.1%(1/32),明显低于SIRS组,二者之间有极显著差异(P＜0.01.急诊手术组SIRS发生率64.7%(22/34),其中感染性SIRS发生率为54.5%(12/22),病死率为22.7%95/22),择期手术组SIRS发生率为58.3%(28/48),其中感染性SIRS发生率为32.1%(9/28),病死率为14.3%(4/28),急诊手术组较择期手术组的SIRS和感染性SIRS发生率及死亡率均明显增高.结论按临床资料,APACHEII评分在7.21以上者有明显的SIRS发生倾向.应针对SIRS的发生机理采取相应的治疗措施,并总结了具有发生SIRS高风险的五种疾病及腹部手术后容易诱发SIRS的因素.

Risk of appendiceal neoplasm after interval appendectomy for complicated appendicitis: A systematic review and meta-analysis

BackgroundNon-operative management is often the treatment of choice in cases of complicated appendicitis and routine interval appendectomy is not usually recommended. Actually, recent studies show an alarming number of appendiceal neoplasms following interval appendectomy. The aim of this study is to evaluate the prevalence of appendiceal neoplasms and their histological types after interval appendectomy for complicated appendicitis in adults.MethodsA comprehensive literature search of the PubMed, Scopus and Web of Science databases was conducted according to the PRISMA statement. Studies reporting appendiceal neoplasm rates after interval appendectomy and histopathological characteristics were included. The most recent World Health Organization (WHO) classification of malignant tumours was considered. A pooled prevalence analysis for both prevalence and pathology was performed.ResultsA total of eight studies was included: seven retrospective series and one randomized controlled trial. The pooled prevalence of neoplasms after interval appendectomy was 11% (95% CI 7–15; I² = 37.5%, p = 0.13). Appendiceal mucinous neoplasms occurred in 43% (95% CI 19–68), adenocarcinoma in 29% (95% CI 6–51), appendiceal neuroendocrine neoplasm in 21% (95% CI 6–36), globet cell carcinoma in 13% (95% CI -2-28), adenoma or serrated lesions in 20% (95% CI -0-41) of cases.ConclusionThe risk of appendiceal neoplasm in patients treated with interval appendectomy for complicated appendicitis is 11%; mucinous neoplasm is the most common histopathological type. Further studies should investigate this association in order to clarify the biological pathway and clinical implications.     

Transthyretin amyloidosis with cardiomyopathy after domino liver transplantation: Results of a cross-sectional study

Domino liver transplantation (DLT) has been used widely in patients with hereditary amyloid transthyretin (ATTR) amyloidosis. New-onset polyneuropathy in recipients of DLT has been reported, but there are few cases of cardiac involvement reported. We aimed to perform a cross-sectional study for ATTR amyloidosis with cardiomyopathy (ATTR-CM) in DLT recipients. We evaluated 23 living DLT recipients a median of 9 years since DLT at 2 referral centers with a systematic cardiac evaluation, including bone scintigraphy. Median age was 72 years, 91% had hypertension, 35% had diabetes mellitus, 67% had chronic renal failure, and 8 patients (35%) developed new-onset polyneuropathy. Only 13% had a normal electrocardiogram and a normal echocardiography, and most of them showed some conduction disturbance or increase in left ventricular wall thickness, but only 1 patient with a Glu89Lys mutation developed ATTR-CM diagnosed by bone scintigraphy and endomyocardial biopsy. None of the recipients of a DLT with Val30Met mutation showed cardiac involvement by bone scintigraphy. In conclusion, DLT from Val30Met donors seems to be safe regarding the development of ATTR-CM. Evaluation of cardiomyopathy in DLT recipients is challenging due to concomitant comorbidities and in this context, bone scintigraphy can be helpful to evaluate ATTR-CM.

参连合用对代谢综合征患者“肠道菌群-免疫反应”的影响

目的　观察参连联合常规西药治疗对代谢综合征（metabolic syndrome, MS）患者糖脂代谢及肠道菌群-免疫反应的影响。方法　选取 2019年 1月—2020年 8月上海交通大学医学院附属同仁医院收治的54例湿热中阻兼气虚型的MS患者作为研究对象,按照随机数字表法分为对照组（常规西药治疗）与治疗组（常规西药+参连联合治疗）,每组各27例。观察2组治疗前后的血糖、血脂、CRP、IL-6、IL-10水平;采用荧光定量PCR法测定肠道细菌DNA,定量分析肠道主要菌群结构变化。结果　与治疗前相比,2组治疗后肠杆菌含量及空腹血糖、TC、TG、LDL-C、CRP、IL-6水平均下降,乳酸杆菌含量、双歧杆菌含量、HDL-C、IL-10水平均升高,其中2组TG、IL-6水平下降及IL-10水平上升差异均有统计学意义,治疗组乳酸杆菌含量升高差异有统计学意义（P均＜0.05）;治疗组IL-10上升幅度及IL-6下降幅度均大于对照组（P均＜0.05）。结论　参连联合常规西药治疗MS患者可提高其外周血免疫炎性因子IL-10水平,降低IL-6水平,明显升高肠道乳酸杆菌含量,对于探索参连联合常规西医治疗的MS患者“肠道菌群-免疫反应”机制研究具有重要意义。
