女贞子、刺五加对T细胞促进作用的实验研究

女贞子和刺五加都是扶正中药.女贞子在体内体外对 T 细胞均有促进作用,但对其作用机理报导很少。刺五加是典型的“适应原样”药物,对机体免疫功能亦有促进作用,但其对 T 细胞的作用尚未见报导.     

Long-term survival after autologous bone marrow transplantation for follicular lymphoma in first remission.

The role of autologous stem cell transplantation (ASCT) in the treatment of follicular lymphoma is still being defined in the era of antibody therapy. Here we report the long-term 12-year clinical outcomes of patients treated with autologous bone marrow transplantation (ABMT) for follicular non-Hodgkin's lymphoma (NHL) in first remission. Between 1988 and 1993, advanced-stage follicular NHL patients in need of initial therapy were enrolled in 2 consecutive prospective treatment trials of either standard-dose CHOP induction (83 patients) or high-dose CHOP plus granulocyte-colony stimulating factor (G-CSF) (20 patients). Patients who achieved an adequate remission with induction therapy underwent conditioning with cyclophosphamide and total body irradiation (TBI) followed by ABMT in first remission using bone marrow (BM) purged in vitro with anti-B cell monoclonal antibodies and rabbit complement (96 patients). At 12-year follow-up, 61% of the patients are alive and 43% remain in continuing complete remission. The only predictors of decreased progression-free survival proved to be histologic BM involvement at time of harvest (hazard ratio [HR] 2.27, 95% confidence interval [CI] 1.3-3.9, P<.004) and PCR detectable disease in the BM product after purging (HR 4.18, 95% CI 1.99-8.8, P=.0002). No significant predictors of overall survival were identified. These results at 12-year follow-up suggest that a subset of follicular lymphoma patients can experience prolonged survival with ABMT in first remission.     

选择性动脉造影在不明原因的下消化道出血诊断中的价值探讨

目的 探讨选择性动脉造影和造影时机选择在不时原因下消化道出血诊断中的价值。方法 运用Seldinger技术对32例患者进行选择性肠系膜上、下动脉及其分支造影,其中少量出血患者17例,中至大量15例。首次出血3例,2次以上反复出血29例。结果 32例中28例发现病变（87.5%）,其中肿瘤性病变（n=15）非肿瘤性病变（n=13）,少理出血未见造影剂外溢征,中至大量出血中造影剂外溢征占33％。结论 选择性动脉造影检查下消化道出血是一种安全、有效的方法,在少量出血和出血间歇期仍有很大价值;造影显示病变部位更重要于显示出血征象。     

结节病患者肺功能变化研究

目的：肺结节病患者肺功能测试的研究。方法：40例肺结节病患者不同时期肺功能测试结果和应用激素的回顾分析。结果：显示此类患者有限性通气功能障碍并伴有弥散功能下降和小气道功能受限,PaO2明显下降,pH升高,PaCO2也有下降的趋势。激素治疗结果显示,患者的MMF有明显的提高。其它肺功能指标如VC,RV,RV/TLC,MVV,FEV1,DLCO等都有升高的趋势。结论：VC,RV,MMF,DLCO,DLCO/VA等对诊断结节病的病情发展有直接参考价值,而MMF在糖皮质激素治疗后有显著的变化,提高MMF对结节病的治疗和预后具有动态参考价值。     

功能性鼻窦内窥镜手术100例疗效观察

目的：功能性鼻窦内窥镜手术的长期疗效。方法：采用Messerklinger术式为100例患者手术;并以传统术式治疗100例作对照。结果：内窥镜组临床治愈率81％,总有效率95％,明显优于传统手术组（P＜0．05）,手术并发症发生率为6％,明显低于传统组（P＜0．05）。结论：内窥镜手术长期疗效可靠,并发症少,复发率低。     

大鼠去势后胸腺变化的组织学及超微结构的观察

目的：探讨去势对大鼠胸腺淋巴细胞超微结构与细胞功能的影响。方法：分别于去势大鼠术后2周、4周、6周、8周后,取胸腺组织进行HE染色和透射电镜观察。结果：实验表明去势导致胸腺淋巴细胞结构坏死,或者细胞器严重受损。结论：去势后胸腺淋巴细胞形态和功能均受到损害。

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.
