    眼化学烧伤是一类常见的眼外伤疾病,特别是在发展中国家。与酸性烧伤相比,碱性烧伤更为常见。碱性物质可快速穿透眼前房,导致慢性炎症和角膜浑浊,从而导致严重且持久的视觉缺损。尽管角膜移植手术是一项有效的治疗方法,然而其成功与否取决于角膜的炎症和新生血管是否得到控制。尽管目前有许多用于治疗角膜炎症和新生血管的药物,然而由于其有一定的副作用或仅仅通过缓解症状而非从根本途径进行治疗,因此亟须从发病机制入手寻找新的治疗办法。 持久的角膜炎症与新生血管,不仅会导致永久的视觉缺失,还会使行角膜手术的时机推迟。碱烧伤常伴随着大量炎症细胞浸润和炎症因子表达上调,促新生血管因子和抗新生血管因子的不平衡是导致新生血管...Ocular chemical burns are a common trauma encountered worldwide particularly in the developing countries. They are more frequently a cause of injury than exposure to injurious acids. Caustic agents can readily penetrate into the anterior ocular surface and produce chronic inflammation and opacification resulting in severe and permanent visual impairment.

Randomly selected 200 cases with normal thyroid function at the same period as the control group( Group E). Retrospective analysis the occurrence rate of thyroid gland dysfunction,the influence of SCH to pregnancy outcome,the doses and influencing factors of replacement therapy by L-T4 to SCH of early pregnant women. Results Relevance ratio of SCH in early pregnant women was5. 20%,the ratio of normal thyroid function was 79. 00%. In group A,premature birth 3. 31%( 8 /242),gestational hypertension 7. 02%( 17 /242),fetal growth restriction 7. 02%( 17 /242),low birth weight infant 6. 61%( 16 /242),were lower than that in group B 8. 79%( 8 /91),14. 29%( 13 /91),15. 38( 14 /91),14. 29( 13 /91) respectively( P < 0. 05). In group C,spontaneous abortion 3. 31%( 6 /181),premature birth 3. 89%( 7 /181),gestational hypertension 8. 29%( 15 /181),gestational diabetes mellitus 3. 89%( 7 /181),fetal growth restriction 7. 73%( 14 /181),low birth weight infant 6. 63%( 12 /181),were lower than that in group D 11. 54%( 6 /52),11. 54%( 6 /52),19. 23%( 10 /52),11. 54%( 6 /52),17. 31( 9 /52),15. 38( 8 /52)( P < 0. 05). No significant statistical difference were found in multiple comparison of the above six indexes of group A,B,C. And just the same as the multiple comparison of group F,G,H,K,E. When TSH reach the standard,the dosage of L-T4 in group A and C had significant difference [( 0. 757 ± 0. 378 vs. 1. 106 ± 0. 454) μg / kg,t = 8. 39,P < 0. 001]. There were also significant differences of group F compared with group H[( 0. 443 ± 0. 198 vs. 0. 813 ± 0. 378) μg/kg,t = 8. 22,P < 0. 001],group( A + F) compared with group( C + H) [( 0. 634 ± 0. 358 and 1. 017 ±0. 427) μg / kg,t = 11. 77,P < 0. 001],group A compared with group F [( 0. 757 ± 0. 378 vs. 0. 443 ± 0. 198) μg / kg,t = 9. 85,P < 0. 001 ],group C compared with group H [( 1. 106 ± 0. 45 vs. 0. 813 ± 0. 378) μg / kg,t = 5. 59,P < 0. 001],group( A + C) compared with group( F + H) [( 0. 932 ±0. 463 vs. 0. 693 ± 0. 388) μg / kg,t = 6. 53,P < 0. 001]. Conclusion The early pregnant women with SCH and TPOAb positive could increase the occurrence rate of spontaneous abortion,premature birth,gestational hypertension,gestational diabetes mellitus,fetal growth restriction and low birth weight infant. The early intervening treatment of L-T4 could efficiently decrease the adverse event occurrence ratio of pregnant woman with SCH and positive TPOAb,but no effect for that with SCH and TPOAb negative. The TSH level and condition of TPOAb could affect the replacement therapy dosage of early pregnancy with SCH

    在21世纪新的经济环境下,经济周期大大缩短、市场变化迅速,基于过去的经验也不再是未来的标杆和指示器。因此,管理的计划和控制职能变得越来越重要,成为企业管理的核心任务,而实现这些职能的一个重要手段就是实行全面预算管理。 随着我国现代企业制度的推行,全面预算管理已成为国有企业集团加强管理的必然选择。虽然大部分国有企业集团采用了预算管理,但许多企业还存在认识上的偏差和误区,预算管理具体实施不科学,在推行预算管理上尚未形成正确的全面预算管理理念,使得全面预算管理实施成效大打折扣,全面预算管理的导向和控制作用未能得到充分发挥。究其原因,主要在于:(1)预算管理的前提不到位,存在制度缺陷和文化缺陷;(2...As the introducing of China's modern enterprise system, comprehensive budget management has become a natural choice for state-owned enterprise groups to strengthen management.
