ObjectiveTo investigate the expression of caspase-3 in the brain of acutely pentylenetetrazole(PTZ)-kindled rats.MethodsThe caspase-3 positive cells were revealed using immunohistochemical SP method. CMIAS image analysis system was used to analyse the expression of caspase-3 hemi-quantitatively. ResultsFollowing PTZ induced epilepsy, the expression of caspase-3 increased both in the hippocampus and in the cortex, and that was more remarkable in the hippocampus than in the cortex.ConclusionCaspase-3 may be activated during neuronal apoptosis after epilepsy. Hippocampus is more sensitive to the neuronal damage due to epilepsy than the cortex is.

Objective To observe the curative effect and recurrence rate of desmopressin acetate(DDAVP) combined with bladder training therapy on primary nocturnal enuresis(PNE) in chlidren.Methods One hundred children with PNE were randomly divided into control group and observation group(50 cases in each group).Children in control group were treated with simple DDAVP,and patients in observation group were treated with bladder training while DDAVP was using.The course of treatment were 3 months.The therapeutic effect between the 2 groups when the treatment was finished was compared and then followed up all the cases for 3 months to compare the near-term and long-term recurrence rate between the 2 groups.SPSS 13.0 software was used to analyze the data.Results The total effective rate in control group was 72.9%,and the near-term recurrence rate and the long-term recurrence rate were 22.9% and 54.3%,respectively.The total effective rate in observation group was 91.3%,and the near-term recurrence rate and the long-term recurrence rate were 11.9% and 28.6%,respectively.The total effective rate was significantly higher in observation group than that in control group(Z=-1.972,P=0.049).The near-term recurrence rate in 2 groups had no significant difference(?2=1.632,P=0.201).The long-term recurrence rate was extremely lower in observation group than that in control group(?2=5.249,P=0.022).Conclusions There is significant curative effect that DDAVP combined with bladder training therapy on PNE in children,and it can lower the long-term recurrence rate.

Objective To evaluate the treament of central retinal artery occlusion by thrombolysis infusion via super selective ophthalmic artery catheterization.Design Retrospective,observational case series.Participants 21 eyes of 21 patients with CRAO. Methods 21 patients with CRAO were diagnosed by stereoscopic color fundus photography and flouorescein fundus angiography, and were treated by urokinase infusion via super select ophthalmic artery catheterization seldinger technique.Main Outcome Measures Visual acuity and the postoperative complications.Results In the 21 patients,10 had showed the occlusion of ophthalmic arterial trunk by super selective internal carotid artery angiography,the others can be found the appearance of ophthalmic arterial trunk and all patients had undergone thrombolysis therapy successfully.Imaging times of central retinal artery before and after thrombolysis infusion treatment are 38.18?10.86 seconds,12.65?3.30 seconds(t=-11.89,P=0.000).Mean foflow-up time is 3.23?1.26 months.After the treatment,the visual acuity was more than 0.25 in 4 patients,improved to different extent in 9 and remained unchanged in 8. Conclusions Super selective arterial catheterization with thrombolysis for CRAO can improve the visual acuity of the patients,a speedy execution of all internal,neurological,and ophthalmology diagnostic measures;and a prompt therapy are necessary.

Objective To investigate the in vitro susceptibility of Minocycline and polymycin B against clinical islates of pan-drug resistant Acinetobacter baumanii ,to provide laboratory support for clinical treatment for drug selection.Methods The susceptible test of Minocycline and polymycin against 39 isolates of pan-drug resistant Acinetobacter baumanii were determined by K-B meth-od.Results 38 strains of pan-resistant Acinetobacter baumanii were sensitive to polymyxin B,sensitive rate was 97.4%,20 strains sensitive to minocycline,the sensitivity rate was 51.3%.polymyxin B sensitivity was more sensitive than Minocycline (P < 0.05). Conclusion Polymycin B had strong activit ies against pan-drug resistant Acinetobacter baumanii .

Objective To compare the short and long term effect of knee osteoarthritis treatment with two therapeutic methods which are simple high cut of fibula and arthroscopic lavage debridement combined with fibular osteotomy.Methods Data of 45 consecutive patients with knee osteoarthritis were retrospectively observed and selected,and then they were divided into two groups according to the operation method.23 patients with simple high cut of fibula were selected as the control group,and 22 patients with arthroscopic lavage debridement combined with fibular osteotomy were selected as the observation group.Results The VAS and AKS scores of the control group at the time of 3m,6m,1 2m were (4.1 3 ±0.76)points,(1 07.04 ±21 .53)points;(2.70 ±0.64)points,(1 41 .1 7 ±1 2.57)points;(2.43 ±0.79)points,(1 48.26 ±5.81 )points;and the scores of the observation group were (3.45 ± 0.60)points,(1 26.64 ±1 4.24)points,(2.70 ±0.73)points,(1 46.45 ±7.26)points,(2.41 ±0.85)points and (1 48.26 ±5.81 )points.The differences between the two groups were statistically significant at the time of 3 months after surgery(t =3.32,-3.62,all P <0.05),the effect of observation group was better than the control group;but the other indices had no statistically significant differences (t =0.51 ,-1 .72,0.1 1 ,-0.20,all P >0.05 ). Conclusion The simple high cut of fibula with small trauma,less cost,less surgical difficulty,and long -term clini-cal curative effect is not less than the arthroscopic lavage and debridement combined with fibular osteotomy.There-fore,it should be carried out in the primary hospitals widely.

Objective To investigate the association of serum angiopoietin-1 (Ang-1) and angiopoietin-2 (Ang-2) with myocardial reperfusion in ST-segment elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (PCI). Methods A total of 103 consecutive STEMI patients who received primary PCI were enrolled in this study. The patients were divided into two groups according to ST-segment resolution (STR) at 2 h after PCI:STR ≥ 50%group (n=69) and STR<50%group (n=34). Serum concentrations of Ang-1, Ang-2 and Ang-2 to Ang-1 ratios (Ang-2/Ang-1) before and immediately after PCI, 2 h, 6 h, 24 h after PCI were compared. Predictors of poor STR were identiifed by multivariable logistic regression analysis. Results The patients with STR≥50%had significant higher serum Ang-1 levels (P < 0.05) and lower Ang-2/Ang-1 ratios (P < 0.01) from before PCI to 6 h after PCI than those with STR < 50%;Ang-1 and Ang-2/Ang-1 at 24 h after PCI, and Ang-2 at all time points were not signiifcantly different between the two groups (P>0.05). In multivariable logistic regression analysis, Ang-2/Ang-1 before PCI was independently associated with STR < 50%;Other independent predictors were pain to balloon time, infarct related artery (LAD), and TIMI flow grade<Ⅲafter PCI. Conclusions Higher Ang-2/Ang-1 is an independent predictor of poor myocardial reperfusion in STEMI patients after PCI.
