OBJECTIVE To investigate the disparation of hemorrhage between the coblation and traditional adenotonsillectomy in children, and find the coping strategies. METHODS The children who had performed the coblation adenotonsillectomy in Tianjin childrens hospital between Jan. 1, 2014 and Dec. 31, 2014 were selected for the coblation group. The children who have performed traditional adenotonsillectomy in Tianjin childrens hospital between Jan. 1, 2010 and Dec. 31, 2010 were selected for the traditional group. The total rate of hemorrhage, the rate of primary hemorrhage, the rate of secondary hemorrhage, the site of bleeding, the degree of bleeding and the management methods of the two groups were compared. RESULTS There were no statistically significant differences in the total rate of hemorrhage, the site and the degree of bleeding, and management methods between the two groups. The rate of primary bleeding in the coblation group was lower than that in traditional group, however the rate of secondary bleeding in the coblation group was higher than that in traditional group. CONCLUSION The coblation assisted adenotonsillectomy does not increase the postoperative bleeding rate in children.

Objective To observe the curative effect of treating chronic renal failure with the prescription Yiqi Shengxie Jiangzhuo decoction,and contrast with recombinant human erythropoietin as well.Methods 72 patients were divided ramdomly into the treatment group and the comparison group.On the basis of fundamental treatment,the treatment group was added Yiqi Shengxie Jiangzhuo decoction,and the comparison group with Erythropoietin as the supplment.The clinical symptoms and signs,and the laboratory indexes were closely observed.Results The index of Hb,RBC and HCT were improved in various degree after the treatment.After the statistics processing,there was remarkable difference(P0.05)between the two groups after that. Both the clinical sympton and the sign had different improvement,and the treatment group has more obvious improvement versus the comparason group(P

Objective:To establish a mouse model of human orbital rhabdomyosarcoma(RD).Methods: RD cells were cultured and implanted subcutaneously into the costal regions of nude mice and severe combined immunodeficiency(SCID) mice(4 weeks old).The nude mice were radiated by ~(60)Co 1 day before the injection.The rhbdomyosarcoma tissue masses were harvested from nude mice and were subcutaneously implanted into the costal regions of another group of BALB/c mice(tumor tissue mass implantation).The tumor growth was observed in all groups and the growth curves were ploted.H-E staining was used to examine pathology of the tumor tissues.Results: Solid tumors were palpable 6-8 weeks after implantation in ~(60)Co radiated nude mice and about 3-4 weeks after implantation in SCID mice.The solid tumors were obviously seen in the nude mice 2 weeks after tumor tissue mass transplantation.The tumor forming rates were 100% in all groups.The tumor growing curves were successfully ploted and the tumors had a progressive growth.Pathological findings of the tumor tissue were similar to those of human orbital rhabdomyosarcoma. Conclusion: The human orbital rhabdomyosarcoma models have been successfully established in nude mice and SCID mice.Tumor tissue mass implantation can shorten the tumor forming time in BALB/c nude mice.This research lays a foundation for further study or human orbital rhabdomyosarcoma.

Abstract: Objective　The tuberculosis data of students registered and reported in Xuzhou from 2016 to 2020 were analyzed to provide a basis for Xuzhou to formulate tuberculosis prevention and control measures in schools. Method　The epidemiological characteristics of tuberculosis among students in Xuzhou from 2016 to 2020 were analyzed based on the data from Tuberculosis Information Management System and Xuzhou Statistical Yearbook 2021. Results　From 2016 to 2020, a total of 574 student tuberculosis patients were registered in Xuzhou, with an annual average registration rate of 5.64/100 000. The reported incidence of tuberculosis among students in Xuzhou showed an increasing trend year by year (χ2trend=22.521, P<0.001). There were 365 males and 209 females, respectively, with a sex ratio of 1.75:1. The tuberculosis patients were mainly in the 15-19 years old group and 20-24 years old group. According to the statistical analysis by different levels of education, students from ordinary higher institutions accounted for 48.61% of the total number of confirmed cases, followed by senior high schools and secondary vocational schools, accounting for 20.91% and 14.46%, respectively. Preschool education had the lowest number of confirmed cases, accounting for 1.05%. There was significant difference in the reported incidence of tuberculosis among students at different educational levels (χ2=1 522.39, P<0.001). The highest incidence was reported in ordinary higher institutions, followed by senior high schools and secondary vocational schools, and the lowest incidence was reported in preschool education. Conclusion　Xuzhou city school tuberculosis epidemic integral is on the rise, we should further strengthen tuberculosis control work of school tuberculosis prevention and control measures of implementation in the future, at the same time to strengthen school tuberculosis prevention knowledge propaganda and standardize the schools for disposal of tuberculosis epidemic situation. We should also further strengthen the newborn matriculation examination and students absent from class because of illness monitoring work.

Numerous pro-apoptotic signal transducing molecules act on mitochondria and provoke the permeabilization of the outer mitochondrial membrane, thereby triggering the release of pro-apoptotic proteins potentially.One of them is much important,which called apoptosis inducing factor(AIF).Upon lethal signaling,AIF released from mitochondria, which translocates, via the cytosol to the nucleus, where it binds to DNA and provokes Caspase-independent chromatin condensation and leading to apoptosis.It has been found gradually that AIF has impotant effect in some malignant cancer cells(such as colorectal carcinoma cell), especially its regulation effect in cell death.Recently some of researches indicate that inducing cell apoptosis by effecting on the releasing or expressing of AIF, has been a new research direction of colorectal carcinoma therapy.
