BACKGROUND Accumulating evidence suggests that the inflammatory cytokine interleukin-6(IL-6)contributes to the pathophysiology of psychiatric ***,there was no study concerning the relationship between IL-6 concentrations and clinical features in the chronic phase of early-onset schizophrenia(EOS).AIM To investigate the relationship between serum IL-6 concentration and the clinical features of *** We measured serum IL-6 Levels from 74 patients with chronic schizophrenia,including 33 with age at onset0.05)after controlling for age,body mass index,and other *** symptom scores were higher in the EOS group than the AOS group(F=6.199,P=0.015).Serum IL-6 concentrations in the EOS group were negatively correlated with both total PANSS-negative symptom score(r=-0.389,P=0.032)and avolition/asociality subscore(r=-0.387,P=0.026).CONCLUSION Patients with EOS may have more severe negative symptoms than those with adult-onset schizophrenia during the chronic phase of the ***-6 signaling may regulate negative symptoms and its avolition/asociality subsymptoms among the early-onset chronic schizophrenic patients.

目的探究宏基因组二代测序(mNGS)对于自发性细菌性腹膜炎患者的早期诊断与预后的价值。方法纳入2021年3月至2023年3月期间肝硬化腹水患者60例。进行腹水培养和腹水mNGS检测。比较mNGS阳性与阴性组患者一般临床资料、APRI指数、FIB-4指数、MELD评分、MELD-Na评分和Child-Pugh评分。采用腹水多核白细胞计数(PMN)联合腹水mNGS诊断自发性细菌性腹膜炎。结果2组患者的基本资料差异无统计学意义(P>0.05)。PMN联合腹水mNGS检测诊断自发性细菌性腹膜炎的敏感度为86.67%,特异度为78.86%。随访结果显示,mNGS阳性组具有更高的不良事件发生率、病死率和肝硬化相关指标评分。腹水mNGS阳性组和腹水mNGS阴性组的MELD评分分别为18.25和13.11、MELD-Na评分分别为23.82±11.77和14.58+11.27、Child-Pugh评分分别为11.25和9.75。结论PMN联合mNGS检测诊断自发性细菌性腹膜炎优于联合腹水培养,mNGS阳性与肝硬化自发性细菌性腹膜炎患者发生不良预后有较高的相关性。

Significantly Enhanced Melt Memory Effect of Metallocene-made Isotactic Polypropylene Containing Talc

引用

Chinese Journal of Polymer Science 2024年第2期42卷 213-222,I0008页

作者： Hong-Wen Sun fu-Shan Wang Yan Gao fu-Qing Wei jia-Chun Feng State Key Laboratory of Molecular Engineering of Polymers Department of Macromolecular ScienceFudan UniversityShanghai200433China Lanzhou Petrochemical Corporation of PetroChina Lanzhou730060China Lanzhou Petrochemical Research Center Petrochemical Research Institute of PetroChinaLanzhou730060China

The melt memory effect is a widely observed phenomenon in semi-crystalline polymers. In practical applications, various additives are usually introduced into polymers, which may affect their melt memory behavior. In this work, the effect of talc on the melt memory effect of metallocene-made isotactic polypropylene(M-PP) was investigated in detail by using the differential scanning calorimetry. The results indicated that the introduction of talc significantly strengthened the melt memory effect of M-PP. Specifically, the upper limit temperature of Domain II increased from 161 ℃ to 174 ℃, resulting in a substantial widening of the temperature range of Domain IIa from 1 ℃ to 14 ℃. Analysis of the crystal orientation of the M-PP containing talc cooled from various Ts suggested that the remarkably enhanced melt memory effect could be ascribed to the stabilization of oriented nuclei facilitated by talc. This stabilizing effect was likely attributable to the prefreezing effect or the sorption interaction between talc and the M-PP chains.
