Objective To study the effects of nitric oxide (NO) on the growth and metastasis of tumor.Methods The literatures of recent years were reviewed.Results NO had double effects on the growth and metastasis of tumor. NO promoted the growth and metastasis by regulating the expression of tumor proliferation gene and inducing tumor angiogenesis. On the other hand, NO had antitumor effects by interfering with the metabolism of tumor cells, inducing the damage of DNA, forming high toxic free radical, inducing apoptosis of tumor cells and mediating the antitumor action of endothelial cells and macrophages.Conclusion Selective blockage or induction of synthesis of NO may be a new way for tumor therapy.

Objective:To investigate the expression of focal adhesion kinase(FAK) and Ki67 in the invasive breast ductal carcinoma tissues, seeking their relationship with tumor invasion and metastasis and to study the mechanisms for cell signaling transduction mediated by FAK in the carcinogenesis and progress of breast carcinoma.Methods:Tissues were obtained from 88 patients with invasive breast ductal carcinoma and 25 with breast ductal epithelial benign proliferative disease. The expression of FAK and Ki67 was examined by immunohistochemical technique(streptavidin peroxidase conjugate method, SP).Results:In 88 cases of invasive breast ductal carcinoma, the positive incidences of FAK was 68.2%(60/88), and the Ki67 proliferation index was 29.6%?22.9%, which distinguished apparently to those of the control group(P0.05). In breast carcinoma tissues, the expression of FAK was positively related to Ki67 proliferation index(P

The development of medical institutes needs not only marvelous hardware construction,but also software strength,such as the hospital culture,brand establishment,etc.Only by the persistent and coordinated development of hardware strength and software strength,can hospital's comprehensive strength and core competitiveness be effectively improved.To enhance hospital software strength,it is necessary to cultivate hospital culture with unique features,emphasize brand establishment,devise long-term development blueprint of medical institutes and activate hospital's potential for further development.

Objective To explore the effectiveness of short-term integrated intervention to reduce discrimination against people living with HIV/AIDS(PLWHA)among medical students.Methods A quasi-experimental survey was conducted.Two medical schools in Beijing,one as intervention group and the other as control group were selected by convenience sampling,from which 123 undergraduate students or interns of medical and nursing specialties were recruited,62 in the intervention group and 61 in the control group.The intervention group was provided with 13 hour long antidiscrimination intervention by increasing HIV/AIDS related knowledge,sympathy and skill in dealing with people living with HIV/AIDS,while the control group was deprived of any intervention.The attitude of the students in the 2 groups were assessed by questionnaire survey in 5 time points after the intervention.Results Compared with the control group,at 4 time points after the intervention students in the intervention group had less discrimination against PLWHA in general;and significantly less discrimination in dealing with them as patients(P

The robust nuclear-cytoplasmic transport is vital for eukaryotes'life cycle.Not only proteins and RNAs are transferred to their destination by this system, the important cellular activities such as mitosis are also regulated by the transport pathways via adjusting the local concentrations of some critical cargoes.tRNA is one of the most important biomacromolecules in the cell, synthesized in nucleus, and taking part in protein synthesis in cytoplasm.It is a long-held belief that tRNA functions only as a key player in protein synthesis, and tRNA nuclear-cytoplasmic transport is a unidirectional movement from nucleus to cytoplasm.However, the recent discoveries are overturning the traditional opinions.Nuclear-born tRNA can be exported out of nucleus, while cytoplasmic-residing tRNA can also be retrogradely transport into nucleus.The new concept tRNA nuclear-cytoplasmic dynamics was coined in 2008 to describe the tRNA communication between nucleus and cytoplasm, which was found able to regulate protein synthesis and cell cycle in S.cerevisiae.The latest results in this field are going to change the landscape of eukaryotic tRNA biology.

Objective To observe the clinical efficacy of scalp acupuncture plus body acupuncture in treating diarrhea-predominant irritable bowel syndrome (D-IBS). Method Totally 122 D-IBS patients were randomized into a scalp acupuncture group (41 cases), a body acupuncture group (41 cases), and a combined group (40 cases). The scalp acupuncture group was intervened by acupuncture at the Stomach and Intestine Zones on the head; the body acupuncture group was by ordinary body acupuncture; the combined group was by both scalp acupuncture and body acupuncture. The symptom score of traditional Chinese medicine (TCM) was evaluated prior to the treatment, at the end of the first and second treatment courses, and after the whole intervention; the clinical efficacies were also compared among the three groups. Result The symptom scores of the combined group were significantly lower than that of the scalp acupuncture group and body acupuncture group respectively at the end of the second treatment course and after the whole intervention (P<0.05); after the whole intervention, the cured and markedly-effective rate was 62.5% in the combined group, significantly higher than 24.4% in the scalp acupuncture group and 29.3% in the body acupuncture group (P<0.05). Conclusion Scalp acupuncture plus body acupuncture can produce a satisfactory clinical efficacy in treating D-IBS, better than body acupuncture or scalp acupuncture alone; its advantages include rapid onset of action, significant effect, and reducing intestinal inflammation, etc.

Objective:To observe the effectiveness and security of piperacillin sodium/sulbactam sodium in the treatment of bacte-rial infections and perform the pharmacoeconomics evaluation. Methods: Totally 126 patients with hand trauma bacterial infections were divided into the control group and the treatment group. The control group was given piperacillin sodium/tazobactam sodium 2. 5g, ivd, bid, while the treatment group was treated with piperacillin sodium/sulbactam sodium 1. 25g, ivd, bid. After 14-day treatment, the clinical therapeutic effect and adverse reactions of the two groups were observed, and the cost-minimization analysis was carried out. Results:The effective rate of the treatment group was 93. 65%while that of the control group was 92. 06%(P>0. 05). The bac-terial clearance rate of the treatment group was 96. 83%while that of the control group was 95. 24% (P>0. 05). The incidence of ad-verse reactions of the treatment group was 4. 76% (3/63) while that of the control group was 9. 52%(P>0. 05). The cost-effective-ness of piperacillin/sulbactam was significantly lower than that of the control group (P<0. 05). Conclusion: The effectiveness and safety of the two groups show no obvious differences in the treatment of hand trauma bacterial infections, and both have good antibacte-rial effect with low incidence of adverse reactions. For the better economic benefits, piperacillin /sulbactam is worthy of promoted ap-plication.
