Abstract
PURPOSE This paper aims to observe the expressions of VEGF and MMP-2 in patients with nasopharyngeal carcinoma treated by nimotuzumab combined with cisplatin. METHODS Altogether, 104 patients with nasopharyngeal carcinoma treated in our hospital from April 2014 to August 2016 were selected as research subjects. Among them, 50 patients treated with cisplatin were divided into a control group and 54 patients treated with nimotuzumab combined with cisplatin were divided into an observation group. The two groups of patients were compared in terms of efficacy after treatment and incidence of adverse reactions. Changes of serum VEGF and MMP-2 concentrations before and after treatment were detected using enzyme-linked immunosorbent assay (ELISA), and the 3-year overall survival (OS) of patients was observed. RESULTS Compared with the control group, patients in the observation group had significantly higher total remission rate (RR) (P < 0.05) and significantly lower incidence of adverse reactions (P < 0.05). Before treatment, there was no significant difference between the observation and control groups in the concentrations of VEGF and MMP-2 (P > 0.05). After treatment, the concentrations in the two groups were significantly lower than those before treatment (P < 0.05), and the concentrations in the observation group were significantly lower than those in the control group (P < 0.05). There was no significant difference in the 3-year OS between the observation and control groups (P > 0.05). CONCLUSIONS Nimotuzumab combined with cisplatin could improve the conditions of patients with nasopharyngeal carcinoma. After treatment, the expression of VEGF and MMP-2 decreased significantly. We speculated that it improves the survival rate of patients by reducing the expression of VEGF and MMP-2.

Abstract
Identification of vulnerable atherosclerotic plaques by imaging the molecular characteristics is intensively studied recently, in which verification of specific markers is the critical step. JAM-A, a junctional membrane protein, is involved in the plaque formation, while it is unknown whether it can serve as a marker for vulnerable plaques. Vulnerable and stable plaques were created in rabbits with high cholesterol diet with or without partial ligation of carotid artery respectively. Significant higher JAM-A expression was found in vulnerable plaques than that in stable plaques. Furthermore, JAM-A was not only expressed in the endothelium, but also abundantly expressed in CD68-positive area. Next, JAM-A antibody conjugated microbubbles (MBJAM-A) or control IgG-conjugated microbubbles (MBC) were developed by conjugating the biotinylated antibodies to the streptavidin modified microbubbles, and visualization by contrast-enhance ultrasound (CEUS). Signal intensity of MBJAM-A was substantially enhanced and prolonged in the vulnerable plaque and some of the MBJAM-A was found colocalized with CD68 positive macrophages. In addition, cell model revealed that MBJAM-A were able to be phagocytized by activated macrophages. Taken together, we have found that increase of JAM-A serves as a marker for vulnerable plaques and targeted CEUS would be possibly a novel non-invasive molecular imaging method for plaque vulnerability.

Abstract
Carnitine is involved in fatty acid metabolism in mammals and is widely used as a nutritional supplement; carnitine orotate is a more absorbable form of carnitine. We investigated the effects of carnitine and carnitine orotate on mouse prolactin-releasing peptide (PrRP) mRNA expression. Twenty-four female mice were randomly divided into four groups of six; control mice were orally drenched with physiological saline solution (250 mg/kg body weight) and treatment mice were orally drenched with carnitine (250 mg/kg) or carnitine orotate (250 or 750 mg/kg), once a day, for 20 days from parturition. The carnitine or carnitine orotate was dissolved in saline solution before administration. The hypothalamus, pituitary and ovary were sampled on day 21 after parturition, and PrRP mRNA levels in these tissues were measured by semi-quantitative PCR, with glyceraldehyde 3-phosphate dehydrogenase as a control. Expression of PrRP in mice treated with carnitine and carnitine orotate was significantly increased in the ovary and significantly reduced in the pituitary gland. Compared with the control, hypothalamus PrRP mRNA increased significantly in the carnitine and low-dose carnitine orotate groups and decreased significantly in the high-dose carnitine orotate group. We conclude that carnitine and carnitine orotate regulate expression of PrRP in the pituitary gland and ovaries.

Abstract
We compared levels of prolactin-releasing peptide (PrRP) mRNA expression in mouse medulla at different stages of pregnancy and lactation. Mouse medulla samples were collected on days 6, 12 and 18 of pregnancy and lactation, respectively (six per group), for mRNA. Expression levels of PrRP mRNA in the medulla were measured by semi-quantitative RT-PCR, with glyceraldehyde 3-phosphate dehydrogenase as a control. PrRP mRNA was highly expressed in mouse medulla oblongata on day 6 of pregnancy (0.53), followed by 0.43 at lactation day 6, and 0.42 at lactation day 12. The expression level of PrRP mRNA on days 12 and 18 of pregnancy and day 18 of lactation shared the same value of 0.36. PrRP mRNA levels during lactation decreased slightly compared with that during pregnancy, but the differences between them were not significant. In summary, PrRP mRNA levels in the medulla oblongata remain relatively stable during pregnancy and lactation. This is evidence that medulla PrRP is not involved in the regulation of prolactin secretion.

Abstract
In response to gamma-radiation-induced DNA damage, organisms either activate cell cycle checkpoint and repair machinery or undergo apoptosis to eliminate damaged cells. Although previous studies indicated that the tumor suppressor p53 is critically involved in mediating both responses, how a cell decides which pathway to take is not well established. The zinc-finger-containing transcription factor, Krüppel-like factor 4 (KLF4), is a crucial mediator for the checkpoint functions of p53 after gamma-irradiation and does so by inhibiting the transition from the G(1) to S and G(2) to M phases of the cell cycle. Here, we determined the role of KLF4 in modulating the apoptotic response following gamma-irradiation. In three independent cell systems including colorectal cancer cells and mouse embryo fibroblasts in which expression of KLF4 could be manipulated, we observed that gamma-irradiated cells underwent apoptosis if KLF4 was absent. In the presence of KLF4, the degree of apoptosis was significantly reduced and cells resorted to checkpoint arrest. The mechanism by which KLF4 accomplished this antiapoptotic effect is by activating expression of the cell cycle arrest gene, p21(WAF1/CIP1), and by inhibiting the ability of p53 to transactivate expression of the proapoptotic gene, BAX. Results of our study illustrate an unexpected antiapoptotic function of KLF4, heretofore considered a tumor suppressor in colorectal cancer, and suggest that KLF4 may be an important determinant of cell fate following gamma-radiation-induced DNA damage.

Abstract
Ethanol and glycerol are both metabolic products of yeasts. There are occasions when coproduction of both is considered desirable in industrial operations. In this article, we describe the potential of integrating the two processes. A LORRE Y8 yeast culture isolated from molasses is capable of efficient glycerol production from glucose, and a yeast Culture 1400 is an excellent producer of ethanol. By controlling the process conditions, the ratio of ethanol and glycerol production can be varied.

Abstract
Intracerebral co-grafting of Schwann's cells and human fetal adrenal medullary tissue was performed in 10 patients with Parkinson's disease. One to six months after grafting, symptoms were improved significantly for 1 to 3 grade. Among them, 2 patients resumed nearly normal daily activities. Long-term follow-up showed that the symptoms were not improved satisfactorily in some patients. It is considered that careful selection of patients, administration of amantadine, and co-grafting of Schwann's cells which prompts the survival of chromaffin cells are essential to better results.
