To investigate the efficacy and safety of minimal y invasive endovascular techniques treatment of hydronephrosis in pregnancy complicated by infection.
65 cases of pregnancy hydronephrosis coinfected patients with minimal y invasive endovascular treatment. Patients were fol owed up for 3-12 months, compared with 48 patients with the same period of conservative treatment .
Ureteral perforation and other surgery-related complications occurred in 65 patients in the observation group has not occurred. The patient's duration of hospitalization、the recurrence rate of postoperative infection, antibiotic duration of treatment, fever days were significantly lower than the control group(P<0.05).
Compared with conservative treatment, minimal y invasive endovascular technical treatment of gestational hydronephrosis co-infection with faster recovery, shorter hospital stay, can significantly reduce the number of days of fever patients and reduce the number of days of antibiotic use, can be used as conventional means of treatment of gestational hydronephrosis infection combined conventional.

OBJECTIVETo investigate whether the decrease in expression of interleukin-2 (IL-2) after trauma is associated with changes in DNA binding activity of nuclear factor of activated T cells (NFAT) and activator protein-1 (AP-1).

METHODSMice with closed impact injury with fracture in both hind limbs were adopted as the trauma model. Spleen lymphocytes were isolated from traumatized mice and stimulated with Con-A. Culture supernatants were assayed for IL-2 activity, and total RNA was extracted from spleen lymphocytes and assayed for IL-2 mRNA. DNA binding activity of NFAT and AP-1 were measured by electrophoretic mobility shift assay (EMSA). The expression of c-Fos, c-Jun and JunB proteins was determined by the Western blot analysis.

RESULTSDNA binding activity of NFAT and AP-1 gradually decreased to a minimum of 41% and 49%, respectively, of the control on the 4th day after injury, which was closely followed by the decline in IL-2 activity and IL-2 mRNA. A decrease in the expression of c-Fos on the 1st and 4th day after trauma had no significant effect on c-Jun expression; the increase in expression of JunB was only on the 1st day after injury.

CONCLUSIONDecreased IL-2 expression is, at least in part, due to a decline in the activation of NFAT and AP-1 in traumatized mice. The decline in DNA binding activity of NFAT and AP-1 is partly due to a trauma-induced block in the expression of c-Fos.
