0.05). Postoperative cataract incidence was higher in the patients without IOL implantation than that in the patients with IOL implantation. Postoperative cataract appeared 6 months after operation in the patients without IOL implantation, while it appeared 14 months after operation in the patients with IOL implantation. There was no significant difference in the postoperative complications between group A and group B. Conclusions Combined surgery is effective and safe for the selected patients of primary retinal detachment accompanied with cataract.

AIM: To observe the effects of some component of Chinese herbs for external use on proliferation of human umbilical vein endothelial cells (HUVEC) and investigate the mechanism of promoting tissue repair. METHODS: The method of MTT was used to examine the effects of Rg1, Rh1, perlolyrine, cinnamyl aldehyde, muscone, astragalus polysaccharin (APS), velver antler polypeptide (VAP) and soluble extract of boswellia carterii birdw (BCB) on proliferation of HUVEC. RESULTS: APS did not promote proliferation of HUVEC at 9.75 mg/L-2.5 g/L; Rh1 promoted proliferation of HUVEC at 1.94 mg/L-0.5 g/L (P

Objective:The poor prognosis of patients with malignant gliomas (MG) has led to the search for new therapeutic strat-egies. Recently, nimotuzumab has been studied as a new anti-EGFR-receptor humanized monoclonal antibody in patients with MG, who showed improvement of outcome and good tolerability. We conducted phase I of our study to determine the toxicity, tolerated dose, and clinical feasibility of nimotuzumab in combination with concurrent chemoradiotherapy for Chinese MG patients after surgical resection. Methods:Patients with pathologically proven grades 3 and 4 glioma were enrolled in the study. The protocol included infu-sions of nimotuzumab plus standard Stupp schedule (postoperative radiotherapy in a total dose of 60 Gy in combination with daily te-mozolomide). Patients received 6 weekly infusions of nimotuzumab at three levels (100, 200, and 400 mg/week). If none of the first three patients enrolled at a dose level experienced dose-limiting toxicity (DLT), the dose was increased, as appropriate. If DLT was ob-served, another three patients were added to the dose level. Results:Nine patients with MG were enrolled, including 7 with grade 3 MG and 2 with glioblastoma. The treatment was well tolerated, and no evidence of grade 3 or 4 adverse events was detected, even at the highest level (400 mg/week). Grade 1 or 2 myelosuppression was the most common toxicity. Three months after treatment, stable dis-ease occurred in 5 patients, whereas progression disease was observed in 4 patients. Conclusion:Nimotuzumab combined with concur-rent chemoradiotherapy was associated with mild toxicity in Chinese MG patients.

AIM:To investigate peripapillary vessel density and its relationship with other ocular parameters in highly myopic eyes with peripapillary intrachoroidal cavitation (PICC), and to analyze risk factors for PICC.METHODS:Cross-sectional study.A total of 35 highly myopic eyes with PICC, 40 highly myopic eyes without PICC and 35 normal eyes were included in this study.All participants underwent fundus photography and spectral-domain optical coherence tomography (SD-OCT).OCT angiography was also performed to image the retinal vasculature in the peripapillary areas of different sectors, including the radial peripapillary capillaries (RPC) and optic nerve head (ONH) layer.The difference of morphology changes in optic disc and peripapillary vessel density between these three groups were compared.Correlations between peripapillary vessel density and PICC and risk factors for the presence of PICC were analyzed.RESULTS: Significant differences were found among the three groups in spherical equivalent refraction (SER), best-corrected visual acuity (BCVA), axial length, peripapillary atrophy β-zone (β-PPA) area, retinal nerve fiber layer (RNFL) thickness and the presence of tilted optic disc, posterior staphyloma and myopic maculopathy (MMD) (P<0.05).There were significant differences among the three groups in the peripapillary vessel density both in RPC (54.34±5.58, 57.54±7.44, 64.42±3.50) and ONH (51.24±7.43, 52.75±9.96, 61.25±4.15) layers (P<0.001).In highly myopic eyes, vessel density was significantly lower in eyes with PICC than in those without in inferotemporal area both in the RPC (56.76±6.62,63.84±6.02,67.52±4.78) and ONH (56.47±5.79,60.38±4.72,64.18±4.37) layers.The vessel density was significantly correlated with the presence of MMD, β-PPA area and RNFL thickness in the RPC layer, whereas correlated with the presence of MMD, PICC and RNFL thickness in the ONH layer (P<0.05).Tilted optic disc and posterior staphyloma were independent risk factors for the presence of PICC (OR=8.007, 95%CI: 2.045-31.348;OR=7.558, 95%CI: 1.398-50.026).CONCLUSION:Highly myopic eyes with PICC had relatively lower peripapillary vessel densities, especially in the temporal area, than those without.Tilted optic disc and posterior staphyloma were independent risk factors for the presence of PICC.

OBJECTIVE To determine the functional role of hydrogen sulfide (H2S) in protecting against mitochondrial dysfunction in heart failure through the inhibition of Ca2 +/calmodulin-dependent protein kinaseⅡ (CaMKⅡ) using wild type and CSE knockout mouse models. METHODS Continuous subcutaneous injection isoprenaline (7.5 mg·kg-1·d-1), once a day for 4 weeks to induce heart failure in Male C57BL/6 (6-8 weeks old) mice and CSE-/- mice. 150 μmol·L-1 H2O2 was used to induce oxidative stress in H9c2 cells. Echocardiograph was used to detect cardiac parameters. H&E stain and Masson stain was to observation histopathological changes. Western blot was used to detect protein expression and activity. The siRNA was used to silence protein expression. HPLC was used to detect H2S level. Biotin assay was used to detect the level of S- sulfhydration protein. RESULTS Treatment with S-propyl-L-cysteine (SPRC) or sodium hydrosulfide (NaHS), modulators of blood H2S levels, attenuated the development of heart failure in animals, reduced lipid peroxidation, and preserved mitochondrial function. The inhibition CaMKⅡ phosphorylation by SPRC and NaHS as demonstrated using both in vivo and in vitro models corresponded with the cardioprotective effects of these compounds. Interestingly, CaMKⅡ activity was found to be elevated in CSE-/- mice as compared to wild type animals and the phosphorylation status of CaMKⅡ appeared to relate to the severity of heart failure. Importantly, in wild type mice SPRC was found to promote S-sulfhydration of CaMKII leading to reduced activity of this protein however, in CSE-/- mice S-sulfhydration was abolished following SPRC treatment. CONCLUSION A novel mechanism depicting a role of S-sulfhydration in the regulation of CaMKⅡ is presented. SPRC mediated S-sulfhydration of CaMKII was found to inhibit CaMKⅡ activity and to preserve cardiovascular homeostasis.
