动态脑电图对癫痫诊断和鉴别诊断的意义

对临床诊断癫痫的５３例和可疑癫痫的１１７例行２４ｈ动态脑电图（ＡＥＥＧ）监测。结果ＡＥＥＧ阳性率（３２．９％）明显高于常规ＥＥＧ（２０％），ＡＥＥＧ痫样放电率在癫痫组为５４．７％（２９／５３），可疑癫痫组为１５．４％（１８／１１７）。后者中有临床发作者６３例，检出痫样放电１０例，睡眠期出现痫样放电占８９．４％（４２／４７）。本文对痫样放电出现与临床发作间的关系以及癫痫诊断和鉴别诊断进行了讨论。     

细胞因子在白血病异基因造血干细胞移植后移植物抗宿主病中的水平及其意义

目的:探究细胞因子TNF-α、IL-6和IL-8在白血病异基因造血干细胞移植后的变化和病情及预后的关系.方法:用放射免疫分析检测了白血病异基因造血干细胞移植患者(48例)、正常健康人(30例)血清TNF-α、IL-6和IL-8水平,对移植后发生或未发生急性移植物抗宿主病(aGVHD)及发生或未发生慢性移植物抗宿主病(cGVHD)进行了比较,并对预后也进行比较.结果:急、慢性GVHD组与未发生急、慢性GVHD组患者的血清TNF-α、IL-6及IL-8水平均高于正常对照组(P＜0.05,除未发生cGVHD组的TNF-α浓度低外);急、慢性GVHD组与未发生急、慢性GVHD组比血清TNF-α、IL-6及IL-8水平均升高(P＜0.05);移植后死亡组生存时间≤6月及＞6月(除＞6月的IL-8水平外)各组TNF、IL-6与IL-8水平均高于同期的存活组(P＜0.05).结论:异基因造血干细胞移植术后动态监测TNF、IL-6、IL-8水平变化有助于对发生aGVHD 或cGVHD的可能提供另一种检测方法,并对判断愈后有一定的临床意义.     

Longitudinal Changes in the Concentration of Major Human Milk Proteins in the First Six Months of Lactation and Their Effects on Infant Growth

Our knowledge related to human milk proteins is still limited. The present study determined the changes in multiple human milk proteins during the first six months of lactation, investigated the influencing factors of milk proteins, and explored the impact of milk proteins on infant growth. A total of 105 lactating women and their full-term infants from China were prospectively surveyed in this research. Milk samples were collected at 1–5 days, 8–14 days, 1 month, and 6 months postpartum. Concentrations of total protein and α-lactalbumin were measured in all milk samples, and concentrations of lactoferrin, osteopontin, total casein, β-casein, α_s−1 casein, and κ-casein were measured in milk from 51 individuals using ultra performance liquid chromatography coupled with mass spectrometry. The concentration of measured proteins in the milk decreased during the first six months of postpartum (p-trend < 0.001). Maternal age, mode of delivery, maternal education, and income impacted the longitudinal changes in milk proteins (p-interaction < 0.05). Concentrations of α_s−1 casein in milk were inversely associated with the weight-for-age Z-scores of the infants (1 m: r −0.29, p 0.038; 6 m: r −0.33, p 0.020). In conclusion, the concentration of proteins in milk decreased over the first six months postpartum, potentially influenced by maternal demographic and delivery factors. Milk protein composition may influence infant weights.

Effect of Jianpi Bushen formula for colon cancer patients who underwent adjuvant chemotherapy: Statistical analysis plan for a multicenter trial

BackgroundPatients with colon cancer who receive chemotherapy usually experience various gastrointestinal adverse reactions, including nausea, vomiting, and diarrhea, which make it challenging for them to adhere to treatment. As an effective traditional Chinese medicine, the Jianpi Bushen formula has been widely used to alleviate the side effects of chemotherapy.ObjectiveTo evaluate the efficacy and safety of Jianpi Bushen formulae for patients who undergo chemotherapy. This statistical analysis plan (SAP) is intended to enhance the transparency and research quality of our randomized controlled trial.MethodsOur study is a multicenter, double-blind, randomized controlled clinical trial. This trial aimed to compare the completion rate of chemotherapy in colon cancer patients who are using and not using Jianpi Bushen formula. To attenuate possible selection bias in the final report, we declared the overall trial design, outcome measures, subgroup analyses, and safety measures. Also, we described the data management and statistical analysis methods in detail.ConclusionThe SAP provides more detailed information than the trial protocol for data management and statistical analysis methods. Further post-hoc analyses can be performed by referring to the SAP, and possible selection bias can be attenuated.

Effect of xiongshao capsule on vascular remodeling in porcine coronary balloon injury model

Objective: To study the effect of Xiongshao capsule (XSC) on vascular remodeling in porcine coronary balloon injury model.Methods: Coronary artery restenosis model was established by oversized balloon injury at mid-region of the left anterior descending coronary artery. They were divided into 5 groups, untreated or treated with probucol, Xueguantong, low and high dose of XSC respectively, and compared. The effect of XSC on late lumen loss resulted from vascular remodeling was evaluated by quantitative histological method with combining histopathological analysis and coronary angiographie examination.Results: The (59 ± 20)% of late lumen loss was caused by vascular remodeling and (41 ± 20)% caused by intimai hyperplasia. Compared with the control group, all the treatment could significantly reduce the late lumen loss after balloon injury (P<0.05 orP < 0.01 ), both low and high dose of XSC could significantly reduce the late lumen loss caused by remodeling (P<0.05 and P<0.01 respectively).Conclusion: Vascular remodeling plays an important role in late lumen stenosis formation in coronary artery after balloon injury. XSC could significantly inhibit the pathological vascular remodeling, and thus reduce the late lumen loss and prevent the restenosis of the injured coronary artery.
