细胞因子在清肝化瘀汤治疗慢性粒细胞性白血病中的研究

目的观察中药清肝化瘀汤治疗慢性粒细胞性白血病(慢性期)的疗效,并探讨细胞因子水平变化的意义。方法收集45例慢性粒细胞性白血病慢性期患者(治疗组),用清肝化瘀汤治疗,观察患者的临床疗效、细胞因子水平。另用20名正常人作为对照(对照组)。结果治疗组完全缓解率40％,部分缓解率46.7％,总有效率86.7％。治疗组细胞因子水平中白介素2、可溶性白介素2受体、肿瘤坏死因子a治疗前后有显著差异(P<0.05);干扰素γ水平变化无显著差异。且与正常对照组比较无显著差异(P>0.05)。结论清肝化瘀汤有清热泻肝解毒、活血化瘀消癥的功效,研究结果显示,该药对慢性粒细胞性白血病慢性期(肝热血瘀型)疗效确切,其作用机理可能与改善细胞因子水平有关。     

Outcomes and factors associated with early mortality in pediatric postcardiotomy veno‐arterial extracorporeal membrane oxygenation

Mortality and morbidity of children received veno‐arterial extracorporeal membrane oxygenation (VA‐ECMO) support after cardiac surgery remain high despite remarkable advances in medical management and devices. The purpose of this study was to describe outcomes and risk factors of applying VA‐ECMO in the surgical pediatric population. We retrospectively analyzed 85 consecutive pediatric patients (aged <18 years) who received postcardiotomy VA‐ECMO from January 2010 to December 2018. Median (IQR) age at ECMO implantation in this cohort was 12.7 (6.4, 43.2) months, median weight was 8.5 (6.0, 12.8) kg, mean ECMO duration was 143.2 ± 81.6 hours and mean hospital length of stay was 48.4 ± 32.4 days. Seventy‐five patients (88.2%) were indicated for postcardiotomy cardiogenic shock. The successful ECMO weaning rate was 70.6% and in‐hospital mortality was 52.9%. The most common diagnosis was transposition of great arteries (n = 18, 21.2%), while acute kidney injury occurred most often (n = 64, 75.3%). Multivariate logistic regression analysis showed that thrombocytopenia, hemolysis, and nosocomial infection were positively correlated with in‐hospital mortality. Multivariate Cox proportional hazard regression analysis presented that thrombocytopenia significantly increased the 180‐day mortality in patients with successful weaning. Therefore, multiple factors had adverse effects on prognosis. Patient selection and procedures from ECMO implantation to weaning need to be closely monitored and performed in a timely manner to improve outcome.     

Complicaciones durante la intubación traqueal repetida en la unidad de cuidados intensivos. Estudio prospectivo,observacional comparando primera intubación y reintubación

Background of the studyThe goal of the study was to compare the incidence of complications, technical difficulty of intubation and physiologic pre-intubation status between the first intubation and reintubation performed on the same patient in an ICU.Materials and methodsThe study was approved by the ethics committee of Galicia (Santiago-Lugo, code No. 2015-012). Due to the observational, noninterventional, and noninvasive design of this study, the need for written consent was waived by the ethics committee of Galicia. Patients requiring tracheal intubation and reintubation in the ICU were included in this prospective observational study. Main endpoint was to compare the incidence of complications, physiologic pre-intubation status, and the rate of technical difficulty of intubation between the first intubation and reintubation performed on the same patient in an ICU.Results and discussion504 patients were intubated in our ICU during the study period, and 82 (16%) required reintubation. There was no difference between the first intubation and reintubation regarding number of total complication (35% vs 33%; P = .86), hypotension (24% vs 24%; P = 1), hypoxia (26% vs 26%; P = 1), esophageal intubation (1% vs 1%; P = 1), and bronchoaspiration (2% vs 1%; P = .86). Physiologic pre-intubation status and technical difficulty of intubation did not differ between the first intubation and reintubation.ConclusionsIn our ICU patients requiring tracheal reintubation, incidence of complications, physiologic pre-intubation status, and technical difficulty of intubation did not differ between the first intubation and reintubation.     

中药解郁胶囊治疗老年抑郁症的临床疗效观察

目的：观察中药解郁胶囊对老年抑郁症的临床疗效和安全性。方法：选取2020年11月至2021年12月甘肃中医药大学附属医院住院或门诊患者200例作为研究对象,按照纳入标准最终产生研究观察对象100例,健康对照组来自我院组织的年龄在60~80岁的健康体检的老年人100例。观察组中男37例,女63例,对照组中男43例,女57例。对照组采取常规治疗,观察组采取中医综合疗法治疗。对2组患者治疗前后减分情况、中医证候分析、服药及依从情况、不良反应及抑郁焦虑因子等无创性指标的影响。结果：对老年抑郁症的治疗效果主要从汉密尔顿抑郁量表减分情况及证候减分率体现,2组经过12个月中药和抗抑郁综合治疗,中医证候量表减分率（8.2±3.1）和（7.8±3.2）,比对照组的（8.8±3）与（8.4±3.6）,P值为0.001 6和0.001 3,治疗前后均有明显变化,差异有统计学意义（P<0.05）,中医证候量表减分率比较,差异有统计学意义（P<0.05）,从服药后出现的不良反应来看,中医综合观察组应明显低于对照观察组,差异有统计学意义（P<0.05）。从中医组治疗患者的依从性分析,差异有统计学意义（P<0.05）。结论：中药解郁胶囊与中医综合治疗患者治疗效果显著,依从性更佳。     

An update on atypical large glandular proliferations of the prostate

The differential diagnosis of prostatic atypical large gland proliferations includes several benign and malignant entities. This review focusses on issues relevant to the practising pathologist, particularly around areas of controversy such as high-grade prostatic intraepithelial neoplasia (HGPIN) and intraductal carcinoma of the prostate (IDCP). HGPIN is a putative precursor of prostate cancer, but its clinical relevance is as a surrogate marker of unsampled prostate cancer, thereby identifying patients who would benefit from a prompt repeat biopsy. The incidence of missed prostate cancer is much lower in contemporary practice due to pre-biopsy MRI and extended sampling protocols so HGPIN is currently less important. It is however important to distinguish HGPIN from PIN-like carcinoma and IDCP. PIN-like carcinoma is considered a histological subtype/variant of acinar prostate carcinoma and should be graded as Gleason pattern 3. A diagnosis of cribriform HGPIN should not be made in needle biopsies as such a proliferation may represent IDCP. This review discusses controversies related to the diagnosis, reporting and management of IDCP. A personalized approach to management of patients with isolated IDCP in needle biopsies that is based on the histological and radiological features of an individual case is outlined.
