Journal of Shanghai Jiaotong University(Medical Science) 2006;0(09):-
Objective To study the effect of myocardial ischemic preconditioning on activity of ATPase and creatine kinase(CK) in high blood fat rat. Methods High blood fat rat mode was established from SD rats.The rats were randomly divided into three groups: ischemic preconditioning(IPC), ischemic/reperfusion(I/R) and control group.The activity of CK in coronary outflow,the activity of malonyldialdehyde(MDA),superoxide dismutase(SOD),glutathione perodxidase(GSH-Px) and ATPase in myocardium were dectected. Results CK and MDA were significantly less in IPC group than those in I/R group.In IPC group,the activity of SOD,GSH-Px,Na~(+)-K~(+)-ATPase,Ca~(2+)-ATPase and Ca~(2+)-Mg~(2+)-ATPase were much higher than those in I/R group. Conclusion Myocardial ischemic preconditioning can protect high blood fat rat from ischemic/reperfusion injury.

34 patients who suffered from NVG, excluding patients with shallow anterior chamber.All patients were assigned to groups A and B according the different therapy.Group A ( 15 eyes ) was treated with Ex -PRESS glaucoma filtration device implantation. Group B ( 19 eyes ) underwent a trabeculectomy combined with mitomycin C. All the patients were followed up to 1a.The results of best-corrected visual acuity ( BCVA ) , intraocular pressure ( lOP ) , the combination of lOP lowering medications, complications were recorded statistically analyzed preoperative and 1d, 1, 4wk, 6 and 12mo after operation. · RESULTS: Mean lOP decreased significantly frompreoperative values in both groups ( P=0.01 ) .The both group had similar lOP values changes after 1, 4wk, 6, 12mo, and there were no significant difference in statistics (P=0.451).There was no significant difference in BCVA changes after operation in both groups ( P =0.832).Success rate was 66.7%and 63.1%at 1a after Ex-PRESS glaucoma filtration device and trabeculectomy, respectively. Anterior chamber bleeding occurred to 8 cases after trabeculectomy in group B and to 3 cases with Ex-PRESS glaucoma filtration device implantation in group A.Choroidal detachment occurred to 3 cases in
group A and 6 cases in group B. No other ocular or systemic adverse events were found during the follow-up duration.
·CONCLUSlON:ln the short-term, Ex-PRESS glaucoma filtration device implantation has the advantages of simpleness, safety, minimally invasive, short learning curve for neovascular glaucoma, which provides us an available strategy to conquer NVG by simply operation and less suffering.

AIM: To investigate therapeutic effects of combination therapy for neovascular glaucoma ( NVG) .
METHODS: This retrospective study comprised 34 eyes of 34 patients who suffered from NVG. All patients were assigned to group A, B, C and D according to the different combination therapies. Group A ( 11 eyes of 11 patients ) was treated with intravitreal injection of ranibizumab and panretinal photocoagulation ( PRP ) . Group B ( 10 eyes of 10 patients ) was treated with transcleral cyclophotocoagulation and PRP. Group C ( 6 eyes of 6 patients) was treated with 3 therapies together. Group D (7 eyes of 7 patients) was treated with 810nm transcleral cyclophotocoagulation and soft gas-permeable contact lenses. All the patients were followed-up for 1a. The best- corrected visual acuity ( BCVA ) , intraocular pressure ( IOP ) were recorded and analyzed prior to operation and 1, 4wk, 6 and 12mo after operation.
RESULTS: All the post treatment IOP decreased significantly ( P<0. 05 ) from the values before therapy, and the IOP values after 4wk, 6, 12mo were not significantly different ( P > 0. 05 ) in statistics. Most patients' IOP can be controlled below 23mmHg after combination therapy. The visual acuity in group A after 1, 4wk, 6mo compared with those before treatment was significantly increased ( P<0. 05 ) in statistics and other groups did not significantly change before and after treatment (P>0. 05). Anterior chamber bleeding occurred to 2 cases after 1wk of transcleral cyclophotocoagulation. No other ocular or systemic adverse events were found during the follow-up duration.
CONCLUSION: After the combination of intraocular injection of the anti - VEGF drugs, 810nm laser cyclophotocoagulation and PRP, most patients with NVG disease can be effectively treated, can effectively control IOP, and retain part of the visual function, significantly improve the quality of life. In the short - term, combination therapy is safe and effective for NVG, which provides us an available strategy to conquer NVG by simply programmable operation and less suffering.

Objective To detect the level of Tnl and T.2 type cytokines in the patients with lym-phoma in order to find out the laboratory evidence of tumor immunotherapy. Methods The levels of serum IFN-γ, TNF-α, IL-2, IL-4, IL-5 and IL-10 were measured by cytometric bead array (CBA) in 92 patients with lymphoma, and 70 normal sera as control. Results The levels of TH1 type cytokincs in 92 patients with lymphoma were: IFN-γ (34.26 ± 33.48) pg/ml, TNF-α (8.17 ± 10. 09) pg/ml, IL-2 (3.74 ±1.72) pg/ml; and the levels of TH2 type cytokines were: IL-10 (6. 28±8.56) pg/ml, IL-5 (3.53 ±3.20) pg/ml, IL-4 (6.22±7.13) pg/ml. The levels of TH1 and TH2 cytokines in lymphoma patients were significantly higher than those in controls(P < 0.01) except TNF-α. And the rate of IL-2/IL-4 was signifi-cantly decreased in lymphoma patients(P <0.01). The level of IL-10 in Ⅲ/Ⅳ stage lymphoma patients was much higher than that in Ⅰ/Ⅱ stage patients(P <0.01). The level of IFN-γ/was significantly decreased in aged patients with lymphoma (P <0. 05). Conclusion TH 1/TH2 is imbalance in lymphoma, which may provide clinical index for the evaluation of progrossien and prognosis. In the lymphoma patients TH1/TH2 shifts to TH2, which may be the mechanism of tumor arising and transferring by immune escape from immu-nosurveillance.

Objective To investigate the effects of rehabilitation training on the microenvironment for axon regeneration and the possible mechanisms promoting axon regeneration,reconstruction and functional compensation after spinal cord injury (SCI) in beagle dogs.Methods Fifteen beagles were divided into a sham operated group,an SCI model group and a rehabilitation training group.Spinal cord hemi-transection injury was carried out.From the 8th day after SCI,the rehabilitation training group was given treadmill training.All dogs were sacrificed 60 days postinjury and samples were harvested.Chondroitin sulphate proteoglycan (CSPG) expression of astroglial cells around the injured area was observed using an immunofluorescence technique.The expression of glial fibrillary acidic protein (GFAP) and CSPG protein in each group were semi-quantified by Western blot analysis.Axon regeneration was observed by silver staining.Motor function was assessed using modified Tarlov scores.Results In the rehabilitation training group,compared with the model group astroglial production of CSPG was reduced remarkably.Both CSPG expression and axon regeneration were enhanced and functional deficits improved.Conclusions Rehabilitation training can inhibit astroglial production of CSPG,improve the microenvironment for injured axon regeneration,and promote reconstruction and functional compensation after traumatic SCI.
