Transforming brain signals related to value evaluation and self‐control into behavioral choices

The processes involved in value evaluation and self‐control are critical when making behavioral choices. However, the evidence linking these two types of processes to behavioral choices in intertemporal decision‐making remains elusive. As the ventromedial prefrontal cortex (vmPFC), striatum, and dorsolateral prefrontal cortex (dlPFC) have been associated with these two processes, we focused on these three regions. We employed functional magnetic resonance imaging during a delayed discounting task (DDT) using a relatively large sample size, three independent samples. We evaluated how much information about a specific choice could be decoded from local patterns in each brain area using multivoxel pattern analysis (MVPA). To investigate the relationship between the dlPFC and vmPFC/striatum regions, we performed a psychophysiological interaction (PPI) analysis. In Experiment I, we found that the vmPFC and dlPFC, but not the striatum, could determine choices in healthy participants. Furthermore, we found that the dlPFC showed significant functional connectivity with the vmPFC, but not the striatum, when making decisions. These results could be replicated in Experiment II with an independent sample of healthy participants. In Experiment III, the choice‐decoding accuracy in the vmPFC and dlPFC was lower in patients with addiction (smokers and participants with Internet gaming disorder) than in healthy participants, and decoding accuracy in the dlPFC was related to impulsivity in addicts. Taken together, our findings may provide neural evidence supporting the hypothesis that value evaluation and self‐control processes both guide the intertemporal choices, and might provide potential neural targets for the diagnosis and treatment of impulsivity‐related brain disorders.     

碱性成纤维细胞生长因子在人体脂肪移植中的应用

目的:碱性成纤维细胞生长因子可促进再血管化过程,有利于脂肪细胞的成活。观察碱性成纤维细胞生长因子在自体脂肪移植治疗面部凹陷畸形中的作用效果。方法:选择2001-11/2006-03于南昌大学第二附属医院整形美容科采用自体脂肪移植治疗面部凹陷畸形的患者60例,共73个部位,所有患者均排除器质性病变且知情同意。按随机数字表法分为2组,每组30例。取出的脂肪经过清洗、过滤备用。①碱性成纤维细胞生长因子组在要移植的脂肪中加入10μg/L的碱性成纤维细胞生长因子和庆大霉素液,每100mL脂肪颗粒中加入庆大霉素8万单位及碱性成纤维细胞生长因子2万单位。②对照组只加入庆大霉素液不加碱性成纤维细胞生长因子。术后半年随访,观察一次注射后的治疗效果。评估标准:凹陷充填后丰满平坦,双侧对称满意者为优;凹陷充填后较丰满平坦,双侧基本对称较满意者为良。结果:①术后半年随访,本组60例患者均使凹陷部位得到不同改善,无一例发生感染、液化及干酪样坏死等并发症。②术后半年碱性成纤维细胞生长因子组优良率为87%,对照组优良率为57%,两组相比差异具有显著性意义(P<0.05)。结论:碱性成纤维细胞生长因子可以促进人体移植脂肪的存活,改善面部凹陷畸形脂肪移植的术后效果。     

Effect of antisense oligonucleotide targeting bFGF on apoptosis of hepatoma cells

Objective： To investigate the cell cycle changes of hepatoma cells and the role of antisense oligonucleotide targeting bFGF. Methods： Inhibition of bFGF protein expression was investigated by confocal microscopy analysis and Western blot in the best condition of transfecting antisense oligonucleotide targeting bFGF. Cell cycle and apoptosis were detected with flow cytometry analysis. Results： Treatment with antisense oligonucleotide of bFGF not only reduced the expression of bFGF by confocal microscopy and Western blot analysises, but also increased the apoptosis of HepG2 cells （ P 〈 0.01）. Conclusion： bFGF may take part in apoptosis regulation of hepatoma cells and be used as a target of hepatocellular carcinoma therapy.     

Cytotoxicity of Chinese motherwort (YiMuCao) aqueous ethanol extract is non-apoptotic and estrogen receptor independent on human breast cancer cells

Background

Motherwort has been used as medicinal herb for many years in both China and Europe. In particular, Chinese motherwort has been commonly used to treat disorders of mammary gland in Chinese traditional medicine (TCM). Chinese motherwort aqueous extract (MAE) was previously reported to have anti-cancer activity in breast cancer cells with low potency (IC50s in a range of 8–40 mg/mL). However, treatment of motherwort ethanol extract in vivo markedly suppressed the development of uterine adenomyosis and mammary cancers in mice. Therefore, anti-cancer activity of Chinese motherwort, especially in a form of ethanol extract, needs to be confirmed further at cellular level.

Materials and methods

Aerial part of Chinese motherwort (Leonurus japonicus Houtt) dry powder is extracted with 70% ethanol and the chemical components were characterized with HPLC finger print as well as mass spectrometry. Cytotoxicity of the motherwort aqueous ethanol extract (MAEE) was analyzed with MTT assay on ER negative MDA-MB-231 and ER positive MCF-7 human breast cancer cell lines. Hoechst 33342 staining and flow cytometry were used to verify whether the cell death induced by MAEE is apoptosis in nature. Cell cycle status of MAEE treated cells were analyzed with flow cytometry.

Results

Our results showed that MAEE caused cell death in a dose-dependent and time-dependent fashion in both ER positive and negative breast cancer cells. Morphology, Hoechst 33342 staining and flow cytometry evidence all indicated the cell death is not in an apoptotic nature. Furthermore, low concentrations of MAEE caused cell cycle arrest at G2/M phase.

Conclusions

These data suggest that Chinese motherwort aqueous ethanol extract may effectively inhibit the proliferation of breast cancer cells through mechanisms of both cytotoxicity and cell cycle arrest. The cellular effects of MAEE are non-apoptotic and ER independent on breast cancer cells.
