Objective To evaluate the clinical practical value of the heart rate viability test in the patients with malignant tumor during their therapies. Methods Totally 187 cases were analyzed and were divided into three different groups, which included 90 malignant tumor patients before therapy, 45 patients with chemotherapy and 52 non-malignant tumor cases (control group). We compared four HRV indexes(ASDNN5,SDANNS, SDNN and RMSSD) of the patients between the different groups as well as inside each group. Results There were statistical significances in the indexes of ASDNN5, SDANN5 and SDNN of patients at different stages before therapy, the three indexes of the stage Ⅲ group were lower than those of the stage Ⅰ group and the control group as well. The three indexes of the stage Ⅳ group compared with the stage Ⅰ group or the control group (P<0.05) were lower either. There was also statistical significances in SDNN between the stage Ⅲ and the stage Ⅱ of the before-therapy group (P< 0. 05). The indexes of SDANN5 and SDNN of the stage Ⅳ in the chemotherapy group were lower than those of the same stage in the before-therapy group(P<0.05). Conclusions The later the stage of malignant tumor patients is, the more the index of HRV declines. Chemotherapy may affect autonomic nerve function of stage Ⅳ patients with malignant tumor and decrease their HRV.

BACKGROUND: At the process of wound healing, the epithelial cells and epidermal stem cells interactions is complicated which promoting the mechanisms of wound healing. The abnormities of any fine phase can be result in delayed healing or scarring. OBJECTIVE: To summarize the characterization of epithelial cells and epidermal stem cells and their interaction in wound healing so that we can recognize the mechanisms of scarring from histomorphology, biochemistry and molecular variations. METHODS: A computer-based online search of Pubmed Database was undertaken to identify the relevant articles on epithelial cell and epidermal stem cells interactions in wound healing and results in scarring published from 1974 to 2009 with the key words of "epithelial cells, epithelial stem cells, wound healing, keratinocytes, fibroblasts, hypertrophic scar, keloid" in English. At the same time, Chinese relevant articles were searched in China Journal Full-text Database (CJFD) published between 1999 and 2009 with the same key words in Chinese. A total of 43 articles were collected about the cell structure (3 articles), the cell interactions in wound healing and scarring (16 articles), the relevant on epithelial stem cells (24 articles).RESULTS AND CONCLUSION: The effect of different cells in epithelial tissue is known to all. The keratinocytes and fibroblasts had been on studying frequently, and their closely correlated to scarring. At present, the epithelial stem cells has been confirmed, but the relevant on their location, quality and specific epidermal markers are unclear which need to study and explore. With the rapidly development of science and technology, we maybe control the expression of cells by genic regulation not only culture the cells of our need but to prevent the scarring.

Insecticidal protein genes from Bacillus thuringiensis are currently the most widely used insect-resistant genes. They have been transferred to many crops for breeding and production. Among them, cotton, maize, potato and other insect-resistant crops are commercialized, creating considerable economic benefit. In this review, we summarized advances in identifying functional genes and transgenic crops for insect resistance, compared different strategies for enhancing vigor of insecticidal protein and utilizing gene stacking as well as listing valuable groups of stacked genes. In addition, the methods for multiple gene transformation was discussed.

Enhanced management of the entire process of medical wastes, ranging from sorting collection, delivery, transport to temporary storage: compilation of the computerized management system for medical wastes: development of quality control inspection standards for medical wastes: all-staff training for the awareness of legal compliance for medical wastes, prevention of medical wastes from jeopardizing both human being and the environment.

Objective To discuss the influence of H1N1 influenza on maternal and fetal outcomes and obstetric management. Methods Totally, data were collected on 19 women, affected by H1N1 influenza and admitted to Shengjing Hospital of China Medical University from November 7, 2009 to December 15,2009, and retrospective analysis was performed on the maternal and fetal outcomes. Results Among the 19 cases, three were( 15. 8%, 3/19) in puerperium, who were all mild cases and recovered. Sixteen (84.2%, 16/19)women were diagnosed as H1N1 influenza during pregnancy, among which two in early pregnancy (12. 5%), seven (43. 8%) in mid-term pregnancy and seven (43. 8%) in late pregnancy. According to the severity of H1N1 influenza, six were mild cases (37. 5% ,6/16), two (12. 5% ,2/16)were severe cases and eight (50. 0% ,8/16)were critical. For these 16 pregnant women, thc two cases in early pregnancy (mild cases) were terminated after recovery from H1N1 influenza. Among the seven mid-term cases, four mild and one of the three severe and critical cases delivered till term, and two of the three severe and critical cases were delivered abdominally because of fetal death intrauterine or maternal severe complications at 27 or 23 weeks of gestation. All of the seven late pregnant cases underwent emergent cesarean section due to maternal or fetal reasons, and two fetuses died in the uterus at late pregnancy and five survived including four preterm babies and one full term baby. Altogether, nine cases (56. 3%, 9/16)underwent emergent cesarean section, and six babies born alive and five survived without any symptom of influenza, two women died (10. 5%,2/19) after the operation. Conclusions Pregnant women during late pregnancy infected by H1N1 influenza are susceptible to develop into severe and critical conditions. Termination of the pregnancy in time is effective in both life-saving of the mothers and babies and prevent neonatal infection against H1N1.
