Résumé
Renal cell carcinoma (RCC),the most common form of kidney cancer,is characteristic by difficult in diagnosis at an early stage,insensitivity to chemoradiotherapy,poor prognosis,etc. . Localized RCC is treated by surgery while advanced RCC is mainly treated by immunotherapy and targeted therapy. With the ongoing in-depth researches on targeted therapy in recent years,plenty of targeted drugs come into the market in succession. Cabozantinib has been approved for the treatment of advanced RCC in the first/ second line setting. It's safety profile and efficiency have been demonstrated in Ⅱ-Ⅲ clinical trials.

Résumé
Objective To observe the effects of Fuzheng Huayu Capsule on the expressions of the main roles, Rock1 and Rock2, in RhoA/Rock signal transduction pathway in rats with myocardial infarction (MI);To explore the possible mechanism of Fuzheng Huayu Capsule to improve ventricular remodeling in myocardial fibrosis. Methods The MI model was induced by ligation of the left coronary artery. Rats with MI were randomly divided into the model group, Fuzheng Huayu group and Fasudil hydrochloride group. A sham-operation group threading without ligation was setting as a control group, with eight rats in each group. The rats were treated with corresponding medicine for 4 weeks from the second day after modeling. The expression of Rock1, Rock2 and its mRNA were detected by immunohistochemical and real-time PCR method. Results The protein expression of Rock1 and Rock2 in model group were significantly higher than those in the sham-operation group (P<0.05). The protein expression of Rock1 and Rock2 in the Fuzheng Huayu group and Fasudil hydrochloride group were lower than those in the model group. The mRNA expression of Rock2 was significantly higher in the model group than that in the sham-operation group (P<0.05). The mRNA expression of Rock1 in the Fasudil hydrochloride group was lower than that in the model group (P<0.05). The mRNA expression of Rock2 in the Fuzheng Huayu group and Fasudil hydrochloride group was lower than that in the model group (P<0.05). Conclusion Fuzheng Huayu Capsule can decrease the expression of Rock1, Rock2 and Rock2 in the marginal zone of myocardial infarction in rats with MI. The anti ventricular remodeling mechanism of Fuzheng Huayu Capsule maybe related with this.
Résumé
Xingnaojing injection has been widely used in the treatment of cerebral vascular diseases, through the following mechanisms: improving the blood-brain barrier (BBB) permeability, anti-oxidant free radical damage, inhibition of excitatory amino acids (EAA) toxicity and calcium overload, inhibition of apoptosis, reducing cerebral edema and inhibition of autophagy. Thus, the paper summarized its progress.

Objective To study the effects of Panax Notoginseng Saponins (PNS) on the damaged expression of ZO-1 of brain microvascular endothelial cells caused by Aβ42.MethodsBrain microvascular endothelial cells were divided into normal control group, model group, PNS low-, medium- and high concentration groups. They were incubated for 24h in 5% CO2 incubator at 37℃ . Then cell vitality was detected by MTT colorimetric method and ZO-1 protein expression was tested by Western blot.Results Stimulation of Aβ42 reduced the activity of microvascular endothelial cells (P<0.01) and suppressed the expression of ZO-1 protein (P<0.01). Compared with the model group, the activity of microvascular endothelial cells of PNS groups, especially the high and medium dose groups (P<0.05), and increased the ZO-1 protein expression. Conclusion PNS can partly recover the barrier function of blood brain barrier through inhibiting the decrease of the activity of microvascular endothelial cells caused by Aβ42.
