2.The effect of shear stress on restenosis of vein grafts
International Journal of Surgery 2009;36(8):559-562
Autogenous vein graft is one of the frequent methods to treat ischemia in Vascular Surgery.However, the patency rate of vein grafts is unhappy because of the injury, the difference structure between arteries and veins, and the change of hemedynamics after grafted. The restenosis of vein graft contains three syntrophic component elements-thrombosis, intima hyperplasia, and scleratheroma. In this article, we will discuss the relationship between the changed hemodynamics and the restenosis of the vein grafts.

Rhabdomyosarcoma is the most common soft tissue sarcoma in childhood.Radiation therapy has been integrated into the primary treatment of most patients with rhabdomyosarcoma, but which in turn potentially induces severe acute and late toxicities.Proton therapy in recent years has been more and more used in the treatment of rhabdomyosarcoma, which is safe and effective, with no serious adverse events.Compared with conventional photon therapy, proton therapy has distinct physical advantages and enables greater precision in the delivery of tumoricidal radiation doses with reduced irradiation of normal tissues, and improves quality of life for patients.Additional follow-up and prospectively studies are needed to determine whether proton therapy truly reduces the incidence and severity of late effects in comparison to patients treated with modern photon techniques.

Background: Chronic obstructive pulmonary disease (COPD) is an important clinical disease, and its global prevalence and mortality rates are high. It is meaningful to investigate the efficacy of integrative respiratory rehabilitation training in quality of life and respiratory physiology of COPD patients in stable phase. Objective: To observe the efficacy of integrative respiratory rehabilitation training in exercise ability and quality of life of COPD patients in stable phase. Design, setting, participants and interventions: Eighty outpatients and inpatients with COPD from Department of Respiratory Medicine, Taihe Hospital, Yunyang Medical College were randomly divided into 4 groups, with 20 patients in each group. The patients in group A only received drug therapy, the patients in group B received traditional qigong training, the patients in group C received modern rehabilitation training, and the patients in group D received integrative respiratory rehabilitation training. Main outcome measures: Chronic respiratory questionnaire (CRQ), 6-minute walking distance and Borg score in each group were examined before and after one-, three-, and six-month and one-year treatment. Results: The 6-minute walking distance, Borg score and CRQ score in group A had no significant changes after treatment (P>0.05). After one-month treatment, there were no significant differences in 6-minute walking distance and Borg score in groups B, C and D as compared with those before treatment (P<0.05). After three-month treatment, 6-minute walking distance and Borg score were improved in groups B, C and D (P<0.05). After six-month and one-year treatment, 6-minute walking distance, Borg score and CRQ score in groups B, C and D were improved as compared with those before treatment (P<0.05), and there were significant differences between group D and any of groups A, B and C (P<0.05). Conclusion: Modern rehabilitation training, traditional qigong training and integrative respiratory rehabilitation training programs all can improve the quality of life and exercise ability of COPD patients, and integrative respiratory rehabilitation training program is better than modern rehabilitation training and traditional qigong training programs. The efficacy of respiratory rehabilitation training is time-dependent, and need long-time adherence to the therapy.

BACKGROUND: The study of isolation, purification, culture, cell labeling, inducing factors, effects of gene transfection on cytobiology, cell carrier construction, and time window for back transplantation of cell compound pertaining to marrow stromal cells (MSCs) is still in its infancy. OBJECTIVE: To search for an in vitro culture method that can be simply and effectively obtained. DESIGN, TIME AND SETTING: The present cytological in vitro experiment was performed at the Beijing Institute of Genome, Chinese Academy of Sciences between June 2006 and July 2007. MATERIALS: Eight specific pathogen-free New Zealand rabbits, aged 6 weeks, were provided by the Laboratory Animal Center, Institute of Genetics and Development, Chinese Academy of Sciences. METHODS: Under sterile condition, 1 mL rabbit bone marrow was taken and diluted with D-Hanks solution. Following centrifugation and subsequent supernatant removal, bone marrow was re-suspended using dulbecco's modified eagle's medium (DMEM) for single cell suspension. Next, single cell suspension was dropped onto the liquid surface of equal-volume lymphocyte separation medium (density: 1.077). Subsequent to centrifugation, cloudlike mononuclear cell layer was collected and re-suspended with DMEM containing 20% fetal bovine serum. The cells were inoculated at lxl0/cm2 and purified by adherent method. When 70%-80% of flask bottom was covered, cell digestion and passage was performed.MAIN OUTCOME MEASURES: Cell growth was observed with an operating microscope. Surviving cells were counted by Trypan blue viability test. Cell identification was performed by hematoxylin-eosin staining. Through the use of 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide assay, cell viability was detected to observe the cellular resuscitation of the cultured cells following cryopreservation. RESULTS: Twenty-four hours after inoculation, cells began to adhere to the wall, exhibiting short shuttle- or triangle-shaped appearance with different sizes of cellular processes. Three days later, adherent cells began to divide, and cell clusters could be found in some areas; One week later, most of cells exhibited scattered fibroblast-like growth; After passage, cells were evenly distributed with long shuttle-shaped appearance and arranged orderly. Following 3 passages, there wound be 5×106-1×107 adherent cells in 1 mL MSC suspension. Approximately 90% of MSCs survived and identified as mononuclear cells. Cells vigorously grew at days 1-6 after inoculation and reached a peak level at day 8, followed by a viability decline. After 56 days of resuscitation, frozen cells displayed a good and rapid growth. CONCLUSION: Highly purified MSCs can be acquired by gradient centrifugation of lymphocyte separation medium. Enough seeded cells can be obtained by in vitro culture and the cellular viability does not change after frozen preservation and resuscitation.
