Objective To explore a better method to establish temporal lobe epilepsy model by administrating drug in brain region.Methods Kainic acid(KA)4 ?g/kg was injected into rat's hippocampus by stereotactic operation.The rat's behavior,EEG and pathological changes were observed.Results After the rat's hippocampus injected with KA,staring,wet-dog shakes,masticatory movement and clonus of limbs occurred successively.The seizures were paroxysmal with rotation,unsettled state of jump and tic of limbs.The rats' behavior gradually recovered to normal after 10 hours.Then the spontaneous seizure(mostly rating 2～4)occurred 1～3 times every week.Cluster electric discharge,spike waves and sharp waves were recorded in cerebral cortex.KA-treated rats could result in hippocampal CA1 and CA3 fields neuronal degeneration and necrosis,especially significant neuron loss was observed in the CA3 field of KA injected ipsilateral side.Conclusions Injection KA in brain region of rat can establish temporal epilepsy model.The symptom,electrophysiology and pathological changes of temporal lobe epilepsy in the rat model are almost the same as those in human being.The KA induced rat model is an ideal tool to research human temporal lobe epilepsy.

By using ~3H—TdR incorporation and CTLL—2 cell line,we observed effects of RU486,anantagonist of type Ⅱ glucocorticoid receptor,on dexamethasone inhibition of lymphocyte prolifer-ation and interleukin—2(IL—2)production in rat spleen.It was shown that RU486 obviouslyantagonized the inhibitory actions of dexamethasone on lymphocyte proliferation and IL—2 pro-duction.By means of dot hybridization and Northern blot analysis,effects of dexamethasone andRU486 on IL—2 gene expression were investigated in lymphocytes of rat spleen.The datademonstrated that dexamethasone markedly decreased IL—2 mRNA production,RU486 alonedidn't affect IL-2 mRNA levels,but obviously reversed dexamethasone-mediated downregala-tion of IL—2 mRNA production in ConA—activated lymphocytes.These results suggest thatthe above effects of dexamethasone may be mediated by glucocorticoid receptor in lymphocytesof rat spleen.

BACKGROUND: It has vedfied that seaweed polysacchande-agarose modifiers have their medical application value. OBJECTIVE: To perform skin regeneration trials using sprayable activated agarose/gelatin solution, and to explore the possibility of egarose modifier as skin dressing for skin regeneration. METHODS: To prepare 3% sprayable mixture with the dissolved activated agarose and gelatin at a certain ratio, and then filtrated with millopore for sterilization to prepare activated agarose (egarose degradation for 8 hours) and gelatin degradation, and made into different ratios (1: 0, 1: 1, 1: 2, 1: 3). A total of four rabbits were obtained, and four sites were selected on the back of each rabbit, totally 16 experimental sites. The sprayable activated agarose/gelatin mixture (1: 1, 1: 2, 1: 3) was directly sprayed on the four lesion sites. Sprayable activated agarose for two sites and simple gelatin for two sites served as controls. The effects of the wounds sprayed with,dressing were observed at 4 weeks following surgery. RESULTS AND CONCLUSION: At 7 days following surgery, the cover film had broken in mixture of activated agarose and gelatin at 1: 3, and remaining three were intact. No infection or inflammation occurred in wound of four ratios. Following comparison, the wound was rapidly healed in 1: 2 ratio dressing. The additional gelatin showed promoting effects on wound healing significantly. Hematoxylin-eosin staining demonstrated that skin with the dressing was similar to autologous skin, which verified that sprayable activated agarose/gelatin have a premise in skin regeneration.

BACKGROUND:For the treatment of distal tibial fractures, open reduction and plate fixation, minimal y invasive percutaneous plate fixation and intramedul ary nail fixation are effective, but each has advantages and disadvantages. OBJECTIVE:To compare the effects of intramedul ary nail combined with blocking screws versus minimal y invasive percutaneous plate fixation in treating distal tibial fractures. METHODS:Fifty-one cases of distal tibial fractures were divided into two groups. The blocking screw group (23 cases) was treated with closed reduction and internal fixation with interlocking nail combined with blocking screws. The plate fixation group (28 cases) was treated with minimal y invasive percutaneous plate fixation. Fracture healing time, recovery of tibial function and complication occurrence were observed during fol ow-up. RESULTS AND CONCLUSION:Al patients were fol owed up for 8 to 32 months. (1) Except one patient in the plate fixation group, the other patients had bony union. The healing time was (4.6±1.7) months in the blocking screw group and (6.9±2.3) months in the plate fixation group. Significant differences in healing time were detected between the two groups (P<0.05). (2) The excel ent and good rate of tibial function recovery was significantly higher in the blocking screw group (100%) than in the plate fixation group (82%) (P<0.05). (3) No significant difference in the incidence of adverse events was determined between the blocking screw group (13%) and plate fixation group (18%) (P>0.05). (4) Results suggested that interlocking intramedul ary nail combined with blocking screw fixation in the treatment of distal tibial fractures can promote fracture healing and joint function recovery.

Objective To explore the clinical feature of Kimura disease complicated with nephrotic syndrome in children. Methods The clinical data from 4 children with Kimura disease complicated with nephrotic syndrome were retrospectively analyzed. Results In all of the 4 male children, level of serum IgE was increased but level of eosinophils was not increased in peripheral blood. The renal pathological manifestations were different among them. Two cases had acute tubular injury, one case had pathological changes in repeated renal biopsy, and one case had a little of eosinophils infiltration in renal interstitium. All of them were sensitive to oral hormone treatment. Except that one case had no relapse yet in short follow-up period, the other 3 cases had relapsed and all manifested as positive urinary protein without lymphadenectasis. The 3 cases with recurrence were treated by combined immunosuppressive agents, the palindromia of two cases were reduced which were combined with tacrolimus. Conclusion The Kimura disease complicated with nephrotic syndrome in children has a long course and different renal pathological manifestations. It is sensitive to hormone treatment but easy to relapse, and the treatment should be combined with immunosuppressive therapy. Tacrolimus may have the effect on reducing relapse and delaying the progress of renal pathology.

Objective To explore the relation between vitamin D deficiency and susceptibility to spinal tuberculosis. Methods A total of 163 hospitalized patients with untreated spinal tuberculosis in Tianjin Haihe hospital were enrolled in this study from June 2013 to May 2016. A total of 170 individuals participated in health examination program at the same period were enrolled as the control group. The serum level of 25-hydroxyvitamin D [25(OH)D] was measured by enzyme linked immunosorbent assay. The 25(OH)D grading included serious deficiency group (<25 nmol/L), deficiency group (≥25 nmol/L and <50 nmol/L), insufficiency group (≥50 nmol/L and <75 nmol/L) and sufficiency group (≥75 nmol/L). Histopathological classification was confirmed by intraoperative findings. Results The serum level of 25(OH)D was significantly lower in patient group [23.99(20.55,29.54)nmol/L] than that of control group [42.94(35.68,51.04) nmol/L] (P<0.01), and which was also significantly lower in four seasons than that of controls (P<0.05). The serum levels of 25(OH)D were significantly higher in summer group than those of winter group in both patient and control groups (P<0.008 3). The proportion of patients with serious deficiency of 25(OH)D was significantly higher in spring and winter groups in patient group, which was significantly lower in summer group (P<0.01). There was no significant difference in patients with serious deficiency of 25(OH)D between four seasons (P<0.01). For control group, there was a higher proportion of cases with deficiency of 25(OH)D in four seasons, and there was no significant difference in the distribution of seasons (P>0.05). In patient group, there were 107 cases of caseous necrosis type, 56 cases of hyperplasia type, and the proportion of caseous necrosis type was significantly higher in the severe deficiency group (79.17%, 76/96) than that of deficiency group (46.27%, 31/67, P<0.01). Conclusion Excluding the effect of season, vitamin D deficiency is associated with susceptibility to spinal tuberculosis and histopathologic classification.
