ObjectiveTo study the biologic distribution of 131I-Herceptin in BALB/c-neu nude mice bearing HER-2 positive SK-BR-3 human breast cancer xenografts and the radioimmunoimaging characteristics of nude mouse bearing human SK-BR-3 breast cancer xenografts. MethodSK-BR-3 breast cancer cells were implanted subcutaneously to athymic mice to establish animal model.Tumor bearing mice were continuously imaged with SPECT. The radiocounting per minute (cpm) of different organ on a γ-arithmometer was measured at 4,12,24,48 h postinjection of 131I-Herceptin or 131I-mlgG,and the T/NT ratios and the uptake percentages per gram of the injection dose (％ ID/g) was gained. ResultsModel was established in 96％ nude mouse.Compared with the control group,there was a significantly stronger contrast enhancement of tumor imaging,bigger T/NT and ％ ID/g in experimental group ( P ＜ 0.0l ).Conclusions 131I-Herceptin concentrates obviously in implanting tumor tissues of nude mouse,hence it is a good radiopharmaceutical agent targeting SK-BR-3 xenografts.

Objective To study the changes of cytokines in children with hand-foot and mouth disease.Methods Sixty-two cases of hand-foot-mouth disease admitted to our hospital from March 2011 to December 2011 were included in this study.Thirty-seven cases were male and 25 cases were female,the youngest one was four month old,and the oldest one was eleven month and 4 years old,the average age was (1.56 ± 0.98) years old.Sixty-two children with hand-foot-mouth disease were devided into ordinary group (n =20),severe group (n =20),critically ill group (n =22).Twenty healthy children served as control group.The plasma levels of pro-inflammatory cytokines [tumor necrosis factor(TNF)-α,interleukin(IL)-1β、IL-6] and anti-inflammatory cytokines (IL-1 0、IL-13、IL-4) were detected.Results The pro-inflammatory and anti-inflammatory cytokines of patients with hand-foot and mouth disease were increased compared with control group.The levels of TNF-α in severe and critically ill groups were (201.45 ± 133.42) ng/L,(220.37 ± 117.54)ng/L respectively,which significantly increased compared with ordinary group [(118.12 ±11205) ng/L] (P ＜0.05).The levels of IL-1β and IL-6 in critically ill cases were (651.77 ±538.45) ng/L and (88.02 ±50.76) ng/L respectively,which significantly increased compared with severe cases [(551.75 ± 252.75) ng/L,(59.25 ± 28.80) ng/L] and ordinary cases [(270.18 ± 249.79) ng/L,(55.76 ± 28.68) ng/L] (P ＜ 0.05).The level of IL-10 was (137.53 ± 72.07) ng/L in ordinary cases,which increased significantly compared with the severe and critically ill cases[(57.07 ±55.02) ng/L,(73.37 ±56.01) ng/L] (P ＜0.05).The levels of IL-13 were (507.53 ±210.86) ng/L and (489.67 ± 168.99) ng/L in severe and critically ill cases respectively,which significantly increased compared with ordinary cases [(387.16± 157.43) ng/L] (P ＜0.05).The levels of IL-4 showed no significant differences among the ordinary,severe and critically ill groups(P ＞ 0.05).Conclusion The pro-and anti-inflammatory cytokines were involved in inflammatory response simultaneously in patients with hand-foot and mouth disease.The increases of TNF-α,IL-1β and IL-6 are consistent with severity of the disease,while factor IL-10,IL-13 are decreased as the severity of the disease.The increase of the pro-inflammatory cytokines and decrease of the anti-inflammatory cytokines are the important sign of the exacerbation.

Objective To observe the expression of aggrecanase 2 and a tissue inhibitor of metalloproteinase 3 (TIMP-3) in degenerate human lumbar intervertebral discs and their role in degeneration of the nucleus pulposus.Methods Pfirrmann classification was used to class degenerate intervertebral discs observed through MRI.They were divided into three groups:a control group (Pfirrmann grade Ⅰ-Ⅱ),a degeneration group (Pfirrmann grade Ⅲ-Ⅳ),and a severe degeneration group (Pfirrmann grade Ⅴ).A total of 45 cases accepted lumbar spine surgery for removing nucleus pulposus specimens.Each group contained 15 cases.After formalin-fixation and paraffin embedding,immunohistochemistry was used to detect aggrecanase 2 and TIMP-3 expression in the nucleus pulposus cells.Results The percentages of cells positive for aggrecanase 2 were (13.58 ± 7.76) ％,(33.48 ± 13.95) ％ and (56.00 ± 18.39) ％ in the control,degeneration and severe degeneration groups respectively.These differences had statistical significance.The percentages of cells positive for TIMP-3 were (34.78 ± 13.80) ％,(46.77 ± 10.98) ％ and (50.65 ± 16.45) ％,and these differences were again statistically significant.The aggrecanase 2/TIMP-3 ratios were also significantly different.Conclusion As the degree of degeneration of the nucleus pulposus increased,the expression of aggrecanase 2 and TIMP-3 rose,which indicates that both changes were closely connected with the degeneration.Their ratio was correlated with the degree of degeneration of the nucleus pulposus.

Objective To make clear the patients in minimally invasive surgery through explo-ring effects of pneumoperitoneum and pulmonary infection on the airway pressure of patients with dif-ferent body mass index (BMI)under general anesthesia.Methods A total of 849 cases of patients with trachea cannula in pneumoperitoneum surgery inr general anesthesia under different position were studied.To observe the changes of airway pressure and the ratio of pulmonary infection within one week of patients in general anesthesia.Propofol,Remifentanil and Atracrium were used in general an-esthesia.BIS and TOF were used to detect the degree of muscle relaxation.Results The airway pres-sure was increased obviously in patients of Head-down Tilt under same pneumoperitoneum pressure(P<0.05);the airway pressure was increased in patients with BMI>30 kg/m2 (P <0.05).There was no obvious increase in pulmonary infection rate in all patients.Conclusion Pneumoperitoneum could increase airway pressure and pulmonary infection of patients with low head position and BMI > 30 kg/m2 under same pneumoperitoneum pressure.Therefore,shorten the operation time and decreased pneumoperitoneum pressure could be used to prevent pulmonary infection.

To lay a foundation for the type selection of the ambulance helicopter. The type selection was explored from the aspects of platform selection, rescue environment and service requirements, analyzing the rescue in the helicopter and the tendency of the ambulance helicopter in foreign countries and China. The types of the am-bulance helicopter were determined as the specific and modified ambulances, with the considerations such as operation environment, flight performance, cabin structure, onboard equipment, cabin configuration, fixation device and protection. Specific ambulance helicopter is supposed to be based on small- or mediate-sized platform, while the modi-fied ambulance helicopter is supposed to be based on large or heavy platform.
