Renin-angiotensin system (RAS) is correlative with many diseases. Angio tensin II (AngII) plays an important role as the final effective approach for RAS. This article reviews the main approach to the action and biosynthesis of AngII: including AngII receptor blocker (ARB), chymase inhibitor and ACE2 which were disscoverd recently.

Autophagy is a crucial biological process in eukaryotes, which is involved in cell growth, survival and energy metabolism. It has been confirmed that autophagy mediates toxicity of anticancer drugs, especially in heart, liver and neuron. It is important to understand the function and mechanism of autophagy in anticancer drugs-induced toxicity. Given that autophagy is a double-edged sword in the maintenance of the function of heart, liver and neuron, the autophagy-mediated toxicity are very complicated in the body. We provide a review on the concept of autophagy and current status about autophagy-mediated toxicity of anticancer drugs. The knowledge is crucial in the basic study of anticancer drugs-induced toxicity, and provides some strategies for the development of alleviating the toxicity of anticancer drugs.

AIM: To study the effect of sphingosine 1-phosphate (S1P) on the increase in microvessel permeability induced by platelet activating factor (PAF). METHODS: The microvessel permeability was assessed by measuring hydraulic conductivity (Lp). To observe the effect of S1P and PAF on vascular endothelial-cadherin (VE-Cadherin), the microvessels were stained with immunofluorescence and examined by laser confocal microscopy. RESULTS: After giving PAF at concentration of 10 nmol/L, the Lp value of rat mesentery microvessel was significantly increased. However, after pretreatment with S1P, PAF did not give rise to a further significant change. The effect of PAF on microvascular endothelial cells could be seen: the formation of endothelial gap was induced, the microvascular fluorescence intensity significantly increased, a large number of fluorescent microspheres (FMs) distributed in the space among the endothelial cells. However, after pretreated with S1P, no obvious gap opening and the FMs accumulation were observed. Compared to normal control, no significant difference of the microvascular fluorescence intensity was found. CONCLUSION: PAF changes the structure of VE-Cadherin, leading to detachment of adherent junction, formation of intercellular gaps, which contributes to the increase in the permeability. S1P improves the increase in the microvessel permeability caused by PAF, which might be mediated by strengthening adherent junction and inhibiting the formation of endothelial gaps.

Objective To research the brain hemodynamic changes in hyperacute cerebral infarction. Methods Focal cerebral ischemia models were presented in 42 healthy New Zealand rabbits by obstructing the unilateral middle cerebral artery with modified O’Brein method. Dynamic scans with intravenous bolus injection of contrast were performed at 0.5, 1, 2, 3, 4, 6h separately after operation by Siemens Somatom Plus 4 Power spiral CT scanner. Then data were input into Siemens Magic View 50 workstation and processed with perfusion CT/VA 10B system. Six cerebral blood functional perfusion maps were obtained. rCBF, rCBV, rTP, rTS of bilateral symmetric interesting regions were calculated. Results Between 0.5-6 hours after operation, the rCBF and rCBV of ischemic cores and peri-ischemic areas decreased subsequently along with times of ischemia developing. rTP、rTS of cores increased at first, then decreased to 0. rTP, rTS of peri-ischemic areas prolonged at all times. Conclusion The ischemic degree, perfusion state of ischemic tissues in brain can be estimated by hemodynamic parameters, which provide useful information for the diagnosis, therapy and prognosis of hyperacute cerebral infarction.

Objective To investigate the expression of long intergenic non-protein coding RNA-regulator of reprogramming (Linc-ROR) in high-grade ovarian serous cancer, and explore the relationship between Linc-ROR expression and biological function of high-grade ovarian serous cancer. Methods A total of 34 high-grade ovarian serous cancer tissue samples and 19 normal fallopian tube tissue samples were collected between June 2014 and February 2016. Real-time reverse transcription (RT)-PCR was used to detect the Linc-ROR mRNA expression in different samples. The relationship between Linc-ROR expression level and ovarian cancer International Federation of Gynecology and Obstetrics (FIGO) stage, lymph node metastasis was analyzed. Constructed Linc-ROR small interference RNA (siRNA) and pIRES2-EGFP-Linc-ROR plasmid, then Linc-ROR siRNA and pIRES2-EGFP-Linc-ROR plasmid were respectively transfected into SKOV3 cells. Cell proliferation, migration and invasion ability were assessed by cell counting kit-8 (CCK-8), wound healing assay and transwell invasion assay. Results (1) The expression level of Linc-ROR mRNA was significantly higher in high-grade ovarian serous cancer than normal fallopian tube tissues (4.31± 0.38 vs 1.03 ± 0.21; t=25.842, P<0.01). With the progression of FIGO stages, the expression of Linc-ROR was increased (F=95.702, P<0.01), and it was associated with lymph node metastasis (t=7.397, P<0.01). (2) The results of RT-PCR showed that the expression level of linc-ROR in Linc-ROR-i group was significantly lower than that in Linc-ROR-NC-i group (0.30 ± 0.11 vs 1.02 ± 0.10; t=15.269, P<0.01). The expression level in Linc-ROR-p group was significantly higher than that in Linc-ROR-NC-p group (8.90 ± 0.45 vs 1.03 ± 0.17;t=21.934, P<0.01). The CCK-8 assay showed that when the cells were cultured for 3, 4, 5 and 6 days, the A value in Linc-ROR-i group was significantly lower than that in Linc-ROR-NC-i group (P<0.05). And the A value in Linc-ROR-p group was significantly higher than that in Linc-ROR-NC-p group (P<0.05). Wound healing assay showed that, after 48 hours incubation, migration rate of cells in Linc-ROR-i group was significantly less than that in the Linc-ROR-NC-i group [(52±4)%vs(67±5)%;t=5.720,P<0.01]. The migration of cells in Linc-ROR-p group was significantly greater than that in the Linc-ROR-NC-p group [(84±4)%vs(66±4)%;t=7.330,P<0.01]. Cell transwell invasion assay showed that, after 48 hours of incubation, the number of invasive cells in Linc-ROR-i group was lower than that in Linc-ROR-NC-i group (74 ± 3 vs 104 ± 3; t=15.810,P<0.01). And the number of invasive cells in Linc-ROR-p group was higher than that in Linc-ROR-NC-p group (217 ± 4 vs 108 ± 5; t=38.060, P<0.01). Conclusion Highly expressed Linc-ROR could enhance the proliferation, migration and invasion ability of high-grade ovarian serous cancer cells, which may be one of the important molecules in the occurrence and development, invasion and metastasis of high-grade ovarian serous cancer.

AIM: To study the protective effects of taurine-magnesium complex (TMC) on endothelium and hemorheology in rats. METHODS: A model of the endothelial damage was made by means of giving rats an injection of adrenaline and making them swim in ice-cold water, then number of circulating endothelial cells (CEC) in whole blood, plasma ET-1 and NO_2~-/NO_3~- content, NOS activity and rheology were determined, respectively. The protective effects of TMC were also observed. RESULTS: An increase in the number of CEC accompanied by abnormal whole blood viscosity, and endothelium-derived ET-1 were observed in model rats. Both the NO_2~-/NO_3~- content and NOS activity were declined significantly in model rats. TMC reduced the number of CEC, resumed NO_2~-/NO_3~- content and NOS activity, and improved the whole blood viscosity in a dose-dependent manner in model rats. CONCLUSION: Ice-cold water bath with adrenaline causes an acute damage of vascular endothelium and abnormal rheology. TMC protects against the injury of vascular endothelium and improves the hemorheology. [

Aim To investigate the effects of TMCC on abnormal L-type calcium current (ICa,L) in rat ventric-ular cardiomyocytes during hypoxia-reoxygenation to find out the mechanism of antiarrhythmic effect. Methods Whole-cell patch clamp was used to record ICa,L in the ventricular cardiomyocytes during hypoxia-reoxygenation in rat under amiodarone and different concentrations of TMCC. Results In hypoxia-reoxy-genation model, peak ICa,L increased from ( 3. 35 ± 0. 50 ) pA/pF to ( 5. 69 ± 0. 25 ) pA/pF ( n =6 , P <0. 01 ) , which was restored to ( 5. 28 ± 0. 18 ) pA/pF (n=6, P>0. 05),(4. 41 ± 0. 22) pA/pF, (3. 82 ± 0. 21)pA/pF(n=6, P<0. 01) by TMCC(100, 200, 400 μmol·L-1 ) and amidodarone 24. 24 μmol·L-1 restored peak ICa,L to(3. 66 ± 0. 27)pA/pF (n=6,P<0. 01 ) . Compared to control group, hypoxia-reoxy-genation turned ICa,L steady-state activation curves to left and inactivation curves to right, which quickened activation and slowed inactivation, TMCC ( 200, 400μmol · L-1 ) and amiodarone could restore the left shift activation curves and right shift inactivation curves. Conclusion TMCC can concentration-de-pendently restore the increase of calcium current due to hypoxia-reoxygenation by promoting inactivation process and inhibiting activation process, and the effect is equal to that of amiodarone. TMCC blocks ICa,L of the ventricular cardiomyocytes, which may be one of its antiarrhythmic mechanisms.
