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 observe the effect of electroacupuncture(EA) onlearning and memoryin vascular dementia (VD) rats andto explore its possible therapeutic mechanism.【Methods】Fifty specific pathogenfree(SPF) adult rats were randomizedintofour groups.Except the 8 rats in the pseudo-operation group(group A),the other 42 rats were induced cerebral ischemia by four-vessel occlusion method.Then the model rats were randomized into model group (group B),EAgroup(group C) and nimotop group(group D).Groups Aand B were fed with the same forage and received no medication.Group Creceived EAonthe acupoints of Baihui,Geshu,Pishu and Shenshu,and EAwas set in continuous wave with the frequency being 150Hz,once per day and lasting 15 consecutive days.Group Dreceived nimotop 12mg/kg,qd,for 15 consecutive days.After 15-day treatment,the learning and memory abilities of the rats were observed by Morris water test,the plasma carbon monoxide(CO) level was detected by double-wavelength spectrophotometer,and brain nitric oxide(NO) content was examined byspectrophotometry-colorimetry.【Results】The model rats had obvious disorders of learningand memory,their escapelatency was prolonged,thetimes swimmingacross the platforminthe original quadrant did not differ fromthose inthe other three quadrants,and plasma COand cerebral NOlevels were obviouslyincreased.In EAgroup,escapelatency was shortened,thetimes swimmingacrossthe platform inthe original quadrant were more thanthose inthe other three quadrants,and plasma COand cerebral NOlevels were obviously decreased(P

Objective:To study the effects of soybean phospholipids on learning and memory abilities and contents of fatty acids in hippocampus of mice and its mechanism. Method:Mice were randomly divided into four groups:low dose(2.5g/kg) ,middle dose(5.0g/kg) and high dose(10.0g/kg) groups of soybean phospholipids and control group. The treatment groups were fed with soybean phospholipids every day while the control group with distilled water for 30 d.After learning and memory abilities were measured,the mice were killed and contents of fatty acids in hippocampus of mice were determined by high performance liquid chromatography(HPLC) . Results:(1) The learning and memory abilities of mice in middle and high dose groups were significantly improved,but only memory abilities in low dose groups were stronger than control group.(2) The contents of protein in hippocampus in middle and high dose groups were increased extremely.(3) The contents of oleic acid(C18:1) and docosahexaenoic acid(DHA,C22:6 ) were obviously enhanced in hippocampus of high dose group;but decreased in eicosapentaenoic acid(EPA,C20:5) and linoleic acid(C18:2) . The content of DHA was increased and EPA decreased significantly in middle dose group.The increase of arachidonic acid(C20:4) was not significant.Conclusion:Soybean phospholipids may improve learning and memory abilities,which might contribute to change of fatty acids contents in hippocampus of mice.

Objective To assess the enhancement characteristic of breast lesions of contrast-enhanced ultrasound (CEUS) in comparison with contrast-enhanced magnetic resonance imaging (MRI).Methods Between August 2011 and March 2013,72 women with 72 lesions were enrolled.All patients underwent ultrasound,CEUS and MRI.The histopathologic results obtained from ultrasound-guided core biopsy or operation excisions were used as the reference standard.CEUS section evaluations were made similar with MRI regarding the size and shape of lesions.Different contrast enhancement patterns including homogeneous/heterogeneous,the tumor areas,the perfusion defect areas,and modality of time-intensity curve were evaluated.Pearson's correlation coefficient,Student's t-tests,and the concordance test were used for evaluation.Results Of the 72 lesions,pathologic examination revealed 56 (77.8％) malignant lesions and 16 (22.2％) benign lesions.The tumor areas measured by CEUS and MRI agreed well,with a correlation of r =0.894,P =0.000.The difference between the two measurements was not significant according to a paired t test (P =0.886).The concordance tests gave a value of the coefficient Kappa =-0.153 (P =0.061),indicating a low concordance between the results obtained with CEUS and those obtained with MRI regarding the enhanced uniformity.There were statistically significant differences in the perfusion defect areas as measured by CEUS and MRI (P =0.01).The CEUS estimates [(0.837 ± 0.827)cm2] were consistently higher than the MRI estimates [(0.576 ± 0.524)cm2].The time-intensity curve patterns between the two groups showed no correlation.Conclusions The enhancement patterns evaluated by CEUS and MRI partly agreed well.There was no direct association between the two methods regarding the enhancement patterns because of the different contrast agent.

This article proposes the "Efficacy Theory" hypothesis of the traditional Chinese medicines (TCMs): TCMs take effects and weaken toxicities through the additive effects of numerous effective forms (including their constituents or/and metabolites) on a same target, the synergistic effects based on the overall action of the additive effects on individual targets and their toxicities scattering effects. A TCM may include approximately 1000 constituents and each constituent may produce about 100 metabolites in vivo after oral administration. Numerous effective forms of incalculable constituents and their metabolites could work like a "army group" together. When the quantity of a specific target molecule is larger than the pharmaceutical molecules, the molecules of different kinds of effective forms could combine with the target molecules successively, to exert the additive effects. When the target molecules are mostly occupied ("target most spaces occupied"), this TCM begins to work. The additive effects maybe exert not only in concentration but also in a time order way, which gives a sustained efficacy of TCM. The additive effects and the toxicities scattering effects are resulted from the same effective groups and not identical toxic groups among different effective form molecules. The "toxicities scattering effect" can be used to explain the non-toxic TCMs, but not fit for toxic TCMs. The efficacy theory showed that the variety of constituents and metabolites may participate in the process of pharmacodynamic actions, including the additive effects, synergy effects and toxicities scattering effects, which may be useful for explaining and developing the characteristic advantage of the TCMs. The questions we need to study or confirm are as follows: What are the TCMs' pharmacodynamic substance basis and mechanism made up of Why are toxicities of most TCMs' smaller How is the TCMs' "Efficacy Theory" which reflects characteristic advantage of TCMs applied in the research and development of new drugs.
