Interleukin-24 (IL-24) is a novel cancer suppressor cytokine. It can suppress cancer cell growth, induce cancer cell apoptosis, inhibit angiogenesis, stimulate the PBMC secretion of cytokines, and enhance the antitumor activity of radiotherapy, chemotherapy and targeting gene-virotherapy. It is reasonable to suggest that IL-24 may be a powerful and effective protocol for combinatorial cancer treatment in the clinic.

The mature Wistar rats were fed with high lipid diet for 8 weeks together with 3 levels (30, 60, or 120mg/day) of dl-?-tocopheryl acetate supplementation. At the end of the experiment, serum vitamin E and lipids were measured by fluorescence analysis and enzymologic method, liver crude fat was measured by Soxhlet method, liver glycogen content and fat accumulation in parenchymal cells were estimated by histo-chemical procedure and liver lipid peroxidation was evaluated by fluorescence analysis respectively. The results showed that the high lipid diet induced hypercholesterolemia and fatty liver associated with a decrease in serum high density lipoprotein cholesterol and an increase in liver peroxidation. Overall vitamin E caused no significant decrease in serum cholesterol and triglyceride levels and no significant increase in high density lipoprotein cholesterol level, except serum vitamin E level had a positive correlation with serum cholesterol level, but could inhibit the neutral fat accumulation in liver cells and liver peroxidation in rats.The levels of serum cholesterol, or the serum vitamin E and VE/CHO were higher in females than those in males significantly when dl-a-tocopheryl acetate was given to the rats fed with high lipid diet.

Objective: To study the elimination half-life of propofol in mouse brain. Methods: One hundred and forty mice were injected with propofol 32 mg/kg through caudal vein. The mice were divided into 14 groups with different time points, i.e. 1,2,3,4,5,6,7,8,9,10,15,30,45,and 60 min,with 10 mice in each group. The mice were killed to obtain arterial blood by picking off their eyeballs, and their brains by cutting off their heads. The concentrations of propofol in serum and brain were measured by high performance liquid chromatography. The parameters of elimination half-life were calculated by software 3P97. Results: Time to peak concentration of propofol in serum was about 1 min, and time to peak concentration of propofol in brain was about 3 min. The elimination half-life of propofol in brain were (9.6? 0.5) mins. Conclusion: The peak concentrations of propofol in brain was later than it in serum. There is correlation between the concentrations of propofol in blood and in brain. The metabolism of propofol in effect site could be measured accurately by the elimination half-life in brain.

Pharmaceutical care thinking is organic combination of the pharmaceutical and clinical thinking. Shang Han Lun contains very rich connotation of the clinical pharmacy, embodies the patient-centered and immediate intervention clinical pharmaceutical service concept in the progress of the diseases. This article sorted out and concluded pharmaceutical care thinking from the aspects of condition assessment and medication selection, medicine taking methods and notes after medication, which provided theoretical supports for the development of clinical pharmacy of TCM.

Anti-neovascularization is an important research direction in the current treatment of gastric cancer.The inhibitors of vascular endothelial growth factor (VEGF) and vascular endothelial growth factor receptor (VEGFR) are main research focus.At present,the inhibitors of the pathways of VEGF and VEGFR in the treatment of advanced gastric cancer include bevacizumab,ramucirumab,apatinib,regorafenib,sorafenib,et al.These drugs provide more possibilities for the treatment of advanced gastric cancer.

Objective[WT5”BZ] To improve the surgical result of circumferential mixed hemorrhoids by using a new technique.[WT5”HZ]Method[WT5”BZ] 371 cases of circumferential mixed hemorrhoids were divided into two groups treated respectively by anal pad preserving(with intact dentate line) respective resection of the internal and external hemorrhoids (RR group) and those treated with routine approach of stripping off the varicose masses of the external hemorrhoids and ligating the internal (control group).[WT5”HZ]Results[WT5”BZ] (1)Cure rates were 84 7%(166/196) in RR group and 74 8%(131/175) in controls, P 0 05.(4) Postoperative complications: a) Postoperative anal pain:mild in 75,moderate in 53 and severe in 68 cases in RR compared with mild in 28,moderate in 47and severe in 100 cases in controls, P 0 05. c) Postoperative urinary dysfunction:26 5%(52/196) in RR and 44 6%(78/175) in controls respectively. d) Tenesmus:7 7%(15/196) in RR and 21 1%(37/175) in controls, P

0.05). The movement and invasion ability were evidently inhibited in AQP1-siRNA groups compared with those in blank control groups and negtive control groups [(36? 3), (23?4)/HP vs(70?5),(65?4)/HP and(72 ?4),(69?4)/HP, respectively, P0.05).CONCLUSION The knock down of AQP1 by RNAi have no effect on the adhesion ability of Hep-2 cells, whereas could prevent the movement and invasion ability of laryngocarcinoma cells, which may be related with the metastasis of laryngeal carcinoma.

Objective To understand morphological characteristics of sinoatrial node cells(SNCs) by taking purified isolation and culture of neonatal rat's SNCs in vitro and to understand the expression characteristics of surface antigens hyperpolarization activated cyclic nucleotide gated cation channel 4(HCN4) and connexin 45(Cx45) on SNCs.Methods The SNCs were isolated from sinus node tissues removed from neonatal rats by trypsin and purified cultured with differential attachment and 5'-bromodeoxyuridine(BrdU) treatment.Results Three different types of cells were observed among the purified cultured SNCs: spindle,triangular and irregular cells.The spindle cells took up the greatest proportion,had the fastest beats,and had less developed organelle and scarce muscular fibrils.Immunofluorescence staining was positive against HCN4 and Cx45 on the spindle cells.Small amounts of HCN4 was observed on triangular cells.Conclusion ① Isolation by trypsin combined with differential attachment and BrdU treatment is a reliable approach to culturing sinoatrial node cells.② The spindle cells with the fastest beats and positive expressions of HCN4 and Cx45 may be the sinus node pacemaker cells.

BACKGROUND:Pericytes, which are widely distributed in the microvasculature except lymphatic vessels, are not only a constituent of microvessels, but also play an important role in microvascular occurrence, development, stability, maturity and remodeling. Its signal transduction is currently a hot spot. OBJECTIVE:To review recent advances in the signal pathways related to pericytes and angiogenesis. METHODS:We retrieved PubMed database, Wanfang database, CNKI database and China Biology Medicine disc for articles addressing pericytes and angiogenesis published from 1994 to 2014. The keywords were “pricytes; endothelial cels; microvessels; signal transduction” in English and Chinese, respectively.RESULTS AND CONCLUSION:In the early stage of capilary formation, recruitment of pericytes contributes to the occurrence and development of new blood capilaries. However, in the late stage of angiogenesis, pericytes inhibit endothelial cel proliferation and promote endothelial cel differentiation, thereby promoting vascular maturation, maintaining normal structure and regulating their permeability. In this process, signaling pathways of platelet-derived growth factor B/platelet-derived growth factor receptor β, transforming growth factor β, angiopoietin-1/Tie-2, human heparin binding epidermal growth factor/ErbBs, and stromal cel derived factor 1α/CXCR4 play an important regulatory role in pericytes and angiogenesis.
