A Ru-arene compound containing two thiosemicarbazone ligands [(η6-p-cymene)Ru(TSC)2 Cl]Cl(1, TSC = benzophenone 4-methylthiosemicarbazone) has been synthesized and characterized by 1 H NMR, elemental analysis and HR-ESI mass spectrometry analysis. The molecular structure was determined by single-crystal X-ray diffraction analysis. The in vitro anticancer activities of the complex have been evaluated against two human cancer cell lines(SGC-7901, BEL-7404), and the IC50 values are 32.5 and 57 μM, respectively.

目的探讨血浆同型半胱氨酸水平与急性脑梗死患者近期预后的关系。方法选取我院2012年2月—2014年2月收治的急性脑梗死患者92例为观察组,同时期在我院体检健康者92例为对照组。观察组患者入院后给予常规治疗及对症治疗,采用荧光标记免疫法检测两组受检者血浆同型半胱氨酸水平,并根据血浆同型半胱氨酸水平将观察组患者分为A组42例(血浆同型半胱氨酸水平>15μmol/L)和B组50例(血浆同型半胱氨酸水平正常)。分别于入院时、入院4周后采用美国国立卫生研究院卒中量表(NIHSS)对观察组患者进行神经功能缺损评分。结果观察组患者血浆同型半胱氨酸水平为(17.73±5.62)μmol/L,高于对照组的(10.66±3.82)μmol/L(P0.05);入院4周后A组患者神经功能缺损评分高于B组(P<0.05)。结论急性脑梗死患者血浆同型半胱氨酸水平较正常人升高,与急性脑梗死的发病有关;血浆同型半胱氨酸水平升高的急性脑梗死患者神经功能缺损程度较重,近期预后较差。

Hepatic ischemia-reperfusion injury（HIRI） is characterized by mitochondrial dysfunction and oxidative stress. Monitoring mitochondrial hydrogen peroxide（mtH2O2） levels in real-time through super-resolution imaging is crucial for elucidating its distribution in live cells and its mechanism of action during HIRI. However, low-background fluorogenic probes have been overlooked in the context of super-resolution imaging. In this study, we developed a low-background fluorogenic probe（MitoWG） with the potential for super-resolution morphology-correlated mitochondrial identification to track the fluctuates of mtH2O2in HIRI. Activation of the desirable fluorescence properties of the probe by mtH2O2was confirmed using structural illumination microscopy（SIM）, enabling high-quality mitochondrial imaging with exceptional specificity and *** in mtH2O2levels were successfully observed in both cellular and rat models of HIRI. Furthermore, we associated the decline in mitochondrial redox homeostasis with accelerated mtH2O2production during HIRI, which triggered mitophagy deficiency and led to cell death. In conclusion, Mito-WG possesses excellent photophysical and low-background properties for SIM imaging, making it a promising tool for mtH2O2tracking in HIRI research and clinical diagnosis.
