AIM: To observe the effect of glucosidorum tr ipterygii tororum (GTT) on cytokine productions in acute graft-versus-host disea se (aGVHD) mice. METHODS : C 57 BL/6 mice were exposed to radiation delivered by a linear accelerator . To es tablish a aGVHD model, the cell suspensions, which were obtained from bone marro w and spleen of the BALB/C mice, were transplanted to the radiated C 57 BL/6 mice. The recipients were treated with GTT, GTT+CsA and CsA+MTX. The serum conc entrations of IL-2, TNF-?, IL-4 and IL-10 were determined by ELISA. RES ULTS: The survival rate on day 11 in GTT group (9/10) was higher than in allogeneic bone marrow transplatation (allo-BMT) group (8/19). The concentratio ns of IL-2 and TNF-? in GTT group were significantly lower, but the concentrati on of IL-10 was remarkably higher than that in allo-BMT group ( P 0 0 5). CONCLUSION: GTT inhibited aGVHD development by regulating th e production of cytokines in the host.

Objective To investigate the effect of early systemic nursing intervention applied by ward nurse on constipation among patients with depression. Methods A total of 144 participants were divided into the intervention group (72 cases) andthe control group (72 cases) by random number table. Except for a period of 4 weeks routine nursing and 4 weeks follow-up observation which were applied for control subjects, systemic nursing interventions werealso conducted inintervention patients. The incidence of constipation and constipation symptom scoreswere measured at the ends of the 4th and 8th week of treatment. Results The incidences of constipation and constipation symptom scores of the 4th and 8th weekend in the intervention group were 17.6% (12/68), 6.59 ± 4.08, 23.5% (16/68) and 6.81 ± 3.99 respectively. While in the control group they were 34.9%(22/63), 8.84 ± 4.45, 44.4%(28/63) and 10.52 ± 3.86 respectively. These differences between two groups at the 4th and 8th weekend were all significant (χ2=5.077, t=3.023, P < 0.05 and χ2=6.413, t=5.411, P < 0.05, respectively). Compared with the 4th weekend, in the 8th weekend, constipation rate and scores of constipation symptom were increased in thecontrol group (P < 0.05), but not in theintervention group (t=-1.965, P > 0.05). Conclusions In patients with depression, early systemic nursing intervention can effectively ameliorate the constipation caused by amitriptyline.

The HBO group mice were treated with 99.2% oxygen under 0.25 MPa for 1.5 hours, while CsA group mice were treated with CsA 0.5 mg?kg -1?d by abdomen injection. After 14 days, the spleen were extracted the contents of malondialdehyde (MDA) and NO and the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), catalase (CAT) and NO synthases (NOS) were determined.RESULTS: (1) Compared with the control group, the transplantation group, HBO group and CsA group have markedly increased the content of MDA and the activities of GSH-PX and CAT; Compared with the transplantation group, the CsA group have markedly increased activity of SOD and reduced activities of GSH-PX and CAT; the HBO group have markedly reduced the activity of GSH-PX and increased the activities of CAT and SOD (P

Objective To discuss the application of digital simulation positioning machine in radiation oncology. Methods We used digital simulation positioning machine to shoot isocenter reset digital simulator images of 0 degrees direction and 90 degrees direction, 10 × 10 cm2 rectangular field and actual time radiation field with any field number. Compared the images taken with the TPS corresponding DRR image through bone marker matching to measure the error of isocenter and actual time radiation field , the linear accelerator Iview-GT system with the same method was shot in rectangular field simulator the same field number EPID image , and the TPS corresponding DRR image. Finally, we compared the measured error of the digital simulator positioning machine with the error of Iview-GT system image. Results The result of measured isocenter error of the digital simulator positioning machine was better than EPID image error (P=0.000). Conclusion The application of digital simulation positioning machine in radiation oncology can be more accurate to measure the error and correct the position deviation, however, it can also make the radiotherapy and the treatment more accurate.
