Age-related macular degeneration (AMD) causes vision loss mainly due to apoptosis of retinal pigment epithelium cells and subsequent degeneration of photoreceptors.Active and passive smoking can increase the incidence of AMD and the progression risk of advanced AMD, and affect the treatment effect of wet AMD.Smoking can cause choroidal vasoconstriction, increased vascular resistance, vascular endothelial dysfunction, thinned choroid and ganglion cell complexes, resulting in impaired vascular reactivity of choroid and retinal vessels.Nicotine in cigarettes can lead to the overexpression of vascular endothelial growth factor (VEGF), which increases the permeability of vessel and proliferation of endothelial cells, thus induces the formation of choroidal neovascularization (CNV). Smoking can induce oxidative stress leading to oxidative damage, reduce the expression of complement factor H, increase the membrane attack complex, lead to macrophage dysfunction, promote the formation of drusen, and induce the formation of CNV.Therefore, a full and deep understanding of the relationship between smoking and CNV and AMD in controlling the occurrence of AMD and preventing the formation of CNV is of great significance for the early prevention of AMD and the exploration of more effective treatment approaches.

Objective To observe the effect of Shenmai injection on congestive heart failure(CHF) and the effect on thyroid hormone as well as medicine security. Methods 52 patieits with CHF were enrolled,Shenmai injection was used with regular western medicine in the treatment. And observed its effect and test serum thyroid hormone: TSH,T3 ,T4 ,rT3. Another 50 CHF patients were enrolled as a control. Results The results of observation were that 25 cases were very effective,23 were effective,4 had no effect and the total effective rate was 92%. The results of control group were that 21 were very effective, 16 were effective, 13 had no effect and the total effective rate was 74%. The differences between the two groups were significant (P > 0.05). By comparing two thyroid hormone T3, T4, rT3, the observation T3 and T4 was obviously higher than the control. rT3 was lower than the control. Conclusion Shenmai injection could efficiently improve the heart function of CHF,cure arrhythmin and correct the illness caused by thyroid hormone.

Objective To evaluate the interobserver reliability and intraobserver reproducibility of the subaxial cervical spine injury classification system (SLIC) and identify its guidance on clinical treatment of spinal cord injuries. Methods Thirty consecutive patients with subaxial cervical injury ad-mitted into our hospital between December 2007 and July 2008 were enrolled in this study and underwent neurological examinations followed by X-ray, CT, and MRI examinations. SLIC was evaluated in aspects of fracture morphology, disco-ligamentous complex (DLC) status and ncurologic status. According to the morphology in image, the fractures were classified into normal, compression, burst, distraction and trans-lation/rotation. According to injury severity, DLC was sorted into intact, indeterminate and disrupted types. Neurologic status was classified into intact, nerve root injury, complete/incomplete spinal cord in-jury and continuous spinal cord compression. The clinical and radiographic data of 30 patients with subax-ial cervical injury were evaluated prospectively by four groups of surgeons to count SLIC scores and decide treatment based on SLIC scores. The evaluation was done again three months later. Cohen' s unweighted kappa coefficients were calculated for the key parameters of each classification system ( morphology, neurologic status, DLCstatus, total score, and proposed management) to analyze the reliability and repreducibility of SLIC. Based on SLIC, the treatment method was selected and the neurological function recovery and the complications observed. Results The interrater Kappa statistics of all subgroups ( morphology, DLCstatus, total score, proposed management) were within the range of moderate to substantial reliability (0.47-0.69). Kappa coefficient was 0.83 for neurologic status, with high reliability. There was no statistical difference upon Kappa values in two evaluations. The interrater Kappa statistics of all sub-groups ( morphology, DLCstatus, total score, proposed management) were within the range of moderate to substantial reproducibility (0.53-0.78). Kappa coefficient was 0.89 for neurologic stares, with high repreducibility. The recovery rate of neuroiogie function was 79.2%. There was no aggravation of neurological status, with low incidence of complications. Conclusions SLIC has advantages of high reliability and reproducibility, simple use, exact evaluation and can facilitate decision-making in treatment of subaxial cervical spine injures.
