OBJECTIVETo explore treatment effect of the locking plate percutaneous external fixation to tibial fractures.

METHODSFrom July 2010 to February 2013, 8 cases with pediatric tibial fractures were treated by using unilateral locking plate percutaneous external fixation,including 6 males and 2 females with an average age of 7 years old ranging from 4 to 10. Among them, 5 cases were open fractures involving 1 case of Gustilo-Anderson type II, 3 cases of type III A, 1 case of type III B; and the other 3 cases were closed fractures involving 2 cases of AO type A3, 1 cases of type B2. The postoperative bone healing and gait impact were observed and the function was evaluated by Johner-Wruhs scores.

RESULTSAll fractures healed successfully without infection. The fracture healing time was from 3 to 6 months with an average of 3.9 months. The locking plate removal time was from 4 to 7 months with an average of 4.3 months. Among them, 7 cases were visually normal after walking with stand, 1 case of anterior tibial tendon defect affected gait. The results of Johner-Wruhs assessment were excellent in 7 cases, good in 1 case. No rub contralateral medial calf skin wounds occurenced.

CONCLUSIONThe method is simple, stable and reliable. The fixation strength is suitable for children using locking plate percutaneous external fixation. The postoperative functional recovery was excellent and the walking gait was less affected. But the point of LCP pedicle screw should be carefully selected before installation with good skin coverage.

Objective To investigate the development and dynamic changes of host immune response in DBA/2 mice infected with Plasmodium yoelii 17XL. Methods Female DBA/2 mice were infected by intraperitoneal ( i. p. ) injection of 106 P. yoelii 17XL parasitized erythrocytes ( PRBC). Levels of IL-12, IFN-γ, IL-4, IL-10 and P. yoelii 17XL-specific antibody in sera were measured by ELISA. Concentrations of NO in cell supernatants were measured by the Griess reaction. Parasitemia,percentage of mononuclear-macrophages of individual mice were monitored daily, and phagocytosis of mononuclear macrophages was also observed. Results Primary parasitemia in vein blood was developed on day 3 postinfection, which peaked with a level of 46. 9% on day 9. Most mice cleared the infection and survived by day 20 postinfection. From day 6 to day 16, the phagocytosis of PRBC by rodent macrophages was observed on the blood smear. Infected mice had a continuously increased level of IL-12 in serum from day 1 postinfection. Accordingly, high level of IFN-γ was also detected in sera from day 1 postinfection,which peaked on day 6. Infected mice produced higher level of IL-4 and IL-10 in serum on day 6 postinfection, which peaked on day 9 and day 15 postinfection respectively. In addition, splenocytes from infected mice produced significantly higher level of NO on day 6 and 20 postinfection. Level of P. yoelii 17XL-specific IgG was determined in the sera of infected mice with a steadily increased trend after infection, which peaked on day 70 postinfection. Conclusions Effective polarizing of Thl cells is significant in inhibition of parasitemia and eventual clearance of the Plasmodium parasites. Activated mononuclear-macrophages play a key role in inhibiting parasitemia in the early phase of infection with P. yoelii 17XL.

Objective To discuss the clinical characteristics of diagnosis and treatment of primary gastric malignant lymphoma (PGML). Method The data from 34 PGML medical records were reviewed retrospectively between January 2001 and May 2008. Results There were 23 cases of B-cell malignant lymphoma, 7 cases of T-cell malignant lymphoma, and 4 cases of non-B and non-T small cell lymphoma. Confirmed by pathology, 14 cases of them had metastasis to lymphoid nodes and 5 cases had invaded the organs nearby. All of these 34 cases had gastroendoscopy before operation. Conclusions PGML has no specific manifestation, and the definitely diagnostic rate of gastroendoscopy is low. The surgical resection is the major therapy.Operative pattern,the size of tumor,pathological stage can predicate the prognosis for PGML.
