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 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.

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.

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.

Objective To investigate the correlations between the clinical manifestations based on pathologic grades and renal pathological features of Henoch - Schonlein purpura nephritis(HSPN)in children. Methods The clinical data of 77 patients with HSPN in the Department of Nephrology,Anhui Provincial Children's Hospital from Ja-nuary 2004 to March 2014 were retrospectively analyzed. The relationship between clinical manifestation and pathologi-cal features was analyzed. Results Among the 77 patients,21 cases(27. 3% )had both abdominal symptoms,and ar-thritis was reported in 15 cases(19. 5% ),28 cases(36. 4% )had abdominal symptoms and arthritis,and 13 cases (16. 9% )had no such symptoms. Hematuria and proteinuria were the most common clinical types[48. 1%(37 / 77 ca-ses)],followed by simple hematuria or proteinuria[27. 3%(21 / 77 cases)],nephrotic syndrome[23. 4%(18 / 77 ca-ses)],and chronic nephritis[1. 3%(1 / 77 cases)]. The major of pathological changes in HSPN were grade Ⅱ[46. 8%(36 / 77 cases)]and grade Ⅲ[45. 5%(35 / 77 cases)],the minority of them were grade Ⅰ[6. 5%(5 / 77 cases)]and grade Ⅳ[1. 3%(1 / 77 cases)]. The severity of urine protein was positively associated with pathologic classification (r s = 0. 472,P = 0. 000). According to the glomerular deposition of immune complex,there were 6 types. The percen-tage of deposition of IgA + IgM was 62. 3%(48 / 77 cases),IgA + IgG + IgM was 19. 5%(15 / 77 cases),IgA 14. 3%(11 / 77 cases),that of IgA + IgG 1. 3%(1 / 77 cases),and the IgM 1. 3%(1 / 77 cases),no Ig 1. 3%(1 / 77 cases). In these cases,76. 6%(59 / 77 cases)had complements C3 deposition;pathologic stage characterized by Ⅲ level and a-bove were common[54. 2%(32 / 59 cases)],Ⅱ level 42. 2%(25 / 29 cases),Ⅰ level 3. 4%(2 / 59 cases). Among the different types of immune complex depositions,there was no statistically significant difference in pathological types of distribution,while the clinical type and complements C3 deposition were significantly associated with pathologic classifi-cation(rs = 0. 361,P = 0. 001). Sixty - two cases were rated as level 1(80. 5% ),and 15 cases was level 2(19. 5% );in different clinical group,rating in glomeruli was statistically different(χ2 = 17. 2,P = 0. 004). Renal tubular interstitial rating of all the patients were level 1(100% ). Conclusions The severity of urine protein,complements C3 deposition is associated with pathologic classification. Pathologic classification can basically reflect the renal damage in HSPN.

Objective To investigate two-dimensional color Doppler commissure real-time shear wave elastrography (SWE) examination and its application value in the diagnosis of breast diseases.Methods One hundred and thirty patients (158 breast lesions) confirmed with breast disease were chosen from September 2013 to September 2014,and all patients underwent two-dimensional color Doppler ultrasound and SWE examination.The receiver operating characteristic (ROC) curve was examined to obtain maximum elasticity modulus value,average elastic modulus value and the corresponding critical value for the diagnosis of benign and malignant breast lesions.According to the results of pathological examination,sensitivity,specificity and accuracy of two-dimensional ultrasound and SWE for the diagnosis of breast lesions were evaluated and compared.Results Of all 158 breast lesions in 130 patients,90 were malignant lesions and 68 were benign lesions.The sensitivities of two-dimensional ultrasound and SWE in diagnosis of breast cancer were 89.7％ and 89.5％,the specificities were 85.6％ and 95.3％ and the accuracy were 87.3％ and 91.4％,respectively.The sensitivity,specificity and accuracy in the diagnosis of breast cancer by combination of two-dimensional ultrasound and SWE were 98.5％,93.3％,95.6％,respectively.Conclusions Although two-dimensional color Doppler ultrasound is a commonly used method in the diagnosis of breast lesions,it has certain limitation.The specificity of diagnosis can be improved by SWE,which is a useful complement to traditional two-dimensional ultrasound technology.Combination of the two methods can significantly increase the sensitivity and accuracy of the diagnosis and provide a reliable basis for the differential diagnosis,reduce the rate of misdiagnosis,missed diagnosis and unnecessary biopsy,which has important clinical application value.
