基于“证治代谢组学”假说探讨中药（单体/复方）药效物质基础的研究思路与实践＊

中药(单体/复方)药效物质基础研究是中医药现代研究的关键问题之一。然而,目前运用的生化和分子生物学方法很难诠释其多靶点、整体性和动态性的整合调节作用。课题组提出的"证治代谢组学"假说理论指出,不同的证候存在"证相关代谢谱群"和"证相关生物标志物",这可能是中药药效物质基础所在,辨证论治后偏离的代谢网络功能呈现回归趋势。基于"证治代谢组学"假说开展中药(单体/复方)药效物质基础研究,这将为阐释中药(单体/复方)防病治病和养生保健的科学内涵及其对疾病个体的整合调节作用提供新的思路。本文以冠心病为研究载体、气阴虚血瘀证为切入点、活血保心丸为干预措施,就该研究思路的内涵与总体模式、提出的背景与依据、实践的方式与可行性、创新与特色及其研究意义等进行了简要介绍。

ELAM-1在鼻咽癌裸鼠移植瘤中的表达及其与转移的关系

目的 建立裸鼠鼻咽癌转移模型并探讨 E-选择素（ELAM-1）与鼻咽癌转移的相关性。方法 将鼻咽癌5-8F细胞悬液注射于裸鼠左后肢爪垫，观察裸鼠状态、成瘤情况并测量裸鼠体重及移植瘤长短径；采用连续病理切片苏木精-伊红染色观察移植瘤及转移情况，将16只人鼻咽癌荷瘤裸鼠分为转移组和非转移组；采用免疫组织化学法检测两组移植瘤组织中ELAM-1的表达。 结果 16只裸鼠均成瘤，成瘤率为100.0%，其中10只裸鼠出现转移瘤，转移率为62.5%。建模前，两组裸鼠体重差异无统计学意义［（13.83±0.56）g vs （14.62±0.30） g，t=1.026，P=0.071］。建模后4~7周，裸鼠瘤体体积呈指数增长，且转移组移植瘤增长速度较非转移组快，非转移组裸鼠瘤体体积小于转移组［（198.91 ± 163.29） mm³ vs （268.76 ±174.31） mm³，t=4.376，P=0.005］。ELAM-1在鼻咽癌裸鼠移植瘤、淋巴结转移灶及远处转移灶中的表达均为阳性，主要表达于细胞膜。转移组移植瘤光密度值高于非转移组（0.4497±0.0705 vs 0.0435±0.0082，t=4.388，P＝0.001）。结论 本研究成功构建稳定性好、转移率高的鼻咽癌裸鼠移植瘤转移模型，且ELAM-1在裸鼠移植瘤中高表达，可促进鼻咽癌裸鼠移植瘤生长和转移。     

经鼻高流量湿化氧疗在小儿先心病术后的疗效观察

目的探析经鼻高流量湿化氧疗用于小儿先心病术后治疗中的效果以及护理措施。方法2014年9月—2017年10月在郑州儿童医院外科监护室接受手术治疗的先心病患儿中随机抽取130例,根据术后氧疗方法不同分组:对照组患儿术后给予常规面罩吸氧,观察组患儿术后给予经鼻高流量湿化氧疗,2组患儿均给予优质术后护理,对比2组的血气指标、住院时间等。结果2组患者氧疗后24h、48h的血氧饱和度差异无统计学意义,在氧疗后24h的PaCO2水平差异无统计学意义,而在氧疗后24h和48h的氧合指数,观察组明显高于对照组,差异有统计学意义(P<0.05);2组ICU入住时间和总住院时间差异无统计学意义(P>0.05)。结论经鼻高流量湿化氧疗的应用提高先心病患儿术后的舒适度,改善呼吸状况,值得推广。     

Long-term health-related quality of life of breast cancer survivors remains impaired compared to the age-matched general population especially in young women. Results from the prospective controlled BREX exercise study

ObjectiveTo investigate long-term health-related quality of life (HRQoL) changes over time in younger compared to older disease-free breast cancer survivors who participated in a prospective randomized exercise trial.MethodsSurvivors (aged 35–68 years) were randomized to a 12-month exercise trial after adjuvant treatment and followed up for ten years. HRQoL was assessed with the generic 15D instrument during follow-up and the younger (baseline age ≤ 50) and older (age >50) survivors’ HRQoL was compared to that of the age-matched general female population (n = 892). The analysis included 342 survivors.ResultsThe decline of HRQoL compared to the population was steeper and recovery slower in the younger survivors (p for interaction < 0.001). The impairment was also larger among the younger survivors (p = 0.027) whose mean HRQoL deteriorated for three years after treatment and started to slowly improve thereafter but still remained below the population level after ten years (difference −0.017, 95% CI: −0.031 to −0.004). The older survivors’ mean HRQoL gradually approached the population level during the first five years but also remained below it at ten years (difference −0.019, 95% CI: −0.031 to −0.007). The largest differences were on the dimensions of sleeping and sexual activity, on which both age groups remained below the population level throughout the follow-up.ConclusionsHRQoL developed differently in younger and older survivors both regarding the most affected dimensions of HRQoL and the timing of the changes during follow-up. HRQoL of both age groups remained below the population level even ten years after treatment.     

外科治疗56例心脏非黏液性肿瘤的临床分析

目的探讨心脏非黏液性肿瘤临床特点,总结外科治疗经验。方法对我院1996年10月至2005年3月进行外科治疗的56例心脏非黏液性肿瘤的临床资料进行回顾性分析,总结其临床表现、发生部位、肿瘤性质和外科治疗特点等。结果心脏非粘液性肿瘤占本院同期手术患者的0.14%,良性肿瘤28例,恶性肿瘤28例,其中继发性心脏肿瘤8例。良性肿瘤最常见的是生长在心室,共18例;恶性肿瘤最常见的生长部位是心房,共15例。外科治疗行急诊手术者12例。心包开窗引流术2例,探查术1例,术中肿瘤全部切除者26例,部分切除27例,术后住院期间死亡1例。结论心脏非黏液性肿瘤临床表现各异、病理类型多样、病变广泛,手术原则为尽可能切除肿瘤和保持心脏结构的完整性和功能。     

肺癌胸膜早期种植转移:螺旋CT与手术病理对照研究

目的:评价CT诊断肺癌胸膜早期种植转移的价值,并分析漏诊原因。方法:回顾性分析43例经手术病理确诊肺癌胸膜种植转移的CT、手术病理资料,作对照研究。结果:43例中,术前CT仅诊断8例,其中Ⅲ级5例,Ⅱ级3例,诊断符合率19%(8/43),CT实际显示胸膜转移结节28例,其中Ⅰ级10例、Ⅱ级13例,Ⅲ级5例,未显示Ⅰ级15例,CT检出率为65%(28/43)。28例中,术前CT漏诊Ⅰ级和Ⅱ级各10例,漏诊率71%(20/28)。20例中,CT漏诊叶间胸膜、肺表面脏层胸膜、纵隔胸膜、肋胸膜、膈胸膜转移,漏诊率分别为0%、33%、36%、43%、80%。结论:CT能准确检出、诊断肺癌中晚期胸膜转移,但检出胸膜早期微小病灶有明显局限性,在CT诊断中,忽视对膈胸膜、肋胸膜、肺表面脏胸膜上Ⅰ、Ⅱ级较早转移灶的观察,是导致漏诊的原因之一。
