本文运用文献计量与内容分析相结合的方法,对2001-2020年间网络化治理研究领域的CSSCI期刊文献进行综合阐释,呈现了网络化治理研究的演进特征、核心议题与发展趋势.据此可将网络化治理研究分为理论编译引介期(2001-2008)与运用稳步拓展期(2009-2020),相应的核心议题主要聚焦于理论发展脉络和领域范围拓展两方面并逐步体现出范式建构与理论创新的鲜明特征.进一步推动网络化治理研究,应将其置于国家治理体系和治理能力现代化的语境下,扎根中国场域,努力构建中国特色网络化治理范式,适时推动网络化治理研究的议题更新.
加强和改进乡村治理需要科学、合理、适切的政策体系保驾护航.文章通过构建"政策工具—目标评价"二维框架对文本进行分析,研究发现:政策工具维度的基本工具偏好从环境型到供给型再到需求型加速递减,"公共资金投入"和"财政措施"等次级工具偏少;目标评价维度的基本工具偏好分布均衡、结构协调,但次级工具结构需进一步优化和完善.进一步分析表明,乡村治理的目标意涵呈现出清晰图景,政策情绪分布比例协调.未来乡村治理的政策制定应遵循四条原则:推进政策工具分布有机平衡,实现次级结构统筹优化;提升政策工具与治理目标契合度,注重补齐政策短板;完善细节设计,提高可操作性;持续推进政策优化升级.
Objective::To compare the stability of two-haptic and four-haptic intraocular lenses (IOL) in high myopic eyes.Methods::In this retrospective case-control study, 148 high myopic patients who received uneventful phacoemulsification with the implantation of a two-haptic IOL (Tecnis ZCB00, AMO) or four-haptic IOL (MC X11 ASP, HumanOptics) during October 2016 to June 2017 at the Eye & ENT Hospital of Fudan University were selected. Of these, 54 were in the two-haptic IOL group, and 94 in the four-haptic IOL group. Follow-up was planned for six months after surgery, including routine postoperative examinations. An OPD-Scan III aberrometer was used to evaluate the decentration and tilt of the IOL, higher-order aberrations, and modulation transfer function. Comparisons of IOL decentration and tilt, and visual qualities were conducted between the two groups. An independent-sample t-test, Mann-Whitney U-test, χ2 test, and Spearman correlation test were used in statistical analyses. Results::No statistically significant difference in terms of age, gender, or best-corrected visual acuity was seen between the two groups. However, significant differences were seen between the decentration of the two-haptic IOL group and the four-haptic IOL group when they were divided into subgroups of axial lengths between 26 mm and <28 mm, and between 28 mm and <30 mm [0.26(0.15, 0.33)mm vs. 0.18(0.10, 0.24)mm, Z=-2.81, P=0.005; (0.42±0.28)mm vs. (0.18±0.07)mm, t=2.96, P=0.01]. Meanwhile, significant correlations were found between decentration and axial length in both the two-haptic IOL group ( r=0.304, P=0.027) and four-haptic IOL group ( r=0.366, P<0.001). Under conditions of a pupil size of 7 mm, better ocular and intraocular higher-order aberrations and coma were seen in the four-haptic IOL group (all P<0.05). Conclusions::For high myopic eyes, the four-haptic IOL seems to be better than the two-haptic IOL in terms of long-term IOL stability and visual quality, especially in low-light conditions.
Objective: To compare the accuracy of three different formulas for intraocular lens power calculation in high myopic eyes with cataract and analyze their influencial factors. Methods: One hundred and three high myopic patients of cataract (103 eyes), with average age of 60.2±8.8 years old (39.0-77.0), including 45 male and 54 female and with axial length ≥ 26 mm were enrolled in this retrospective case-series study. All of them underwent routine ocular examination and IOLMastermeasurement preoperatively and then underwent phacoemulsification through temporal clear-corneal incision with implantation of HumanOptic posterior chamber Intraocular lens (IOL). All analyses were conducted using SPSS version 19.0. Repeated-measures analysis of variance was applied to compare the refractive results one month postoperatively with the predicted IOL powers calculated by SRK/T, Holladay 1, or Haigis formula before surgery. The differences were further compared based on different grouping of axial length (AXL), corneal curvature (K) and corneal astigmatism (CA). The accuracies of the three formulas were analyzed using Bland-Altman analyses and the possible error sources of each formula were analyzed using multiple regression model. Results: The majority of patients enrolled had hyperopic shift after cataract surgery. The mean errors (ME) of the three formulas were SRK/T: 0.70±0.89D, Holladay 1: (1.20±0.88) D and Haigis: (0.60±0.88) D; the mean absolute errors (MAE) of the three formulas were (0.81±0.79) D, (1.23±0.84) D and (0.76±0.74) D, respectively. Both ME and MAE of Holladay formula were significantly greater than the other two formulas (F=86.31, P<0.01). Besides, the proportion of patients having a prediction error within 0.50 D was lower in those using Holladay formula (20.4%, 21/103) than the other two (SRK/T: 38.8%, 40/103, χ(2)=8.41, P<0.01, Haigis: 45.6%, 47/103, χ(2)=14.84, P<0.01). Bland-Altman analyses showed that the accuracies of all the three formulas were acceptable in patients of cataract with high myopia in clinical practice. ME and MAE tended to be larger with longer axial length, larger corneal curvature and astigmatism of the patients in all three formulas. However, in eyes with axial length> 30 mm or corneal curvature ≤43.00 D, the MAE of Haigis formula was lower than that of SRK/T formula (F=63.26,63.94, both P<0.01). The prediction error of SRK/T formula was positively correlated with axial length and corneal astigmatism (F=33.97, r=0.66, β=0.48, P<0.01 and β=0.42, P<0.01), while for Holladay and Haigis formulas, in addition to the previous two factors, the errors were also positively correlated with mean corneal curvature (Holladay 1: F=31.26, r=0.72, AXL: β=0.52, P<0.01, K: β=0.20, P<0.05 and CA: β=0.37, P<0.01; Haigis: F=30.96, r=0.72, AXL: β=0.33, P<0.01, K: β=0.40, P<0.01 and CA: β=0.37, P<0.01). Conclusions: In the selection of IOL formula for high myopic patients with cataract, Haigis or SRK/T would reduce the prediction error and serve as the more accurate formulas than Holladay 1. Haigis formula may be more accurate than SRK/T formula in case of AXL>30 mm or K≤43.00 D. (Chin J Ophthalmol, 2017, 53: 260-265).
疱疹性口炎为婴幼儿常见的急性口腔黏膜感染性疾病,病原体为单纯疱疹病毒I型(HSV I),潜伏期约为1周,患者年龄越小,全身反应越剧烈(发热、烦躁、流涎、啼哭、拒食等),口腔症状越重,多发生于6月龄~3岁幼儿。临床表现为:唇、颊、舌、牙龈及上腭黏膜红肿,出现成簇与散在2 mm左右的小水疱,或破溃形成糜烂,糜烂可相互融合成片,口周或唇红部的水疱破溃后,可出现糜烂、渗出、结痂[1]。目前临床上治疗疱疹性口炎常用口服抗病毒口服液及外用利巴韦林气雾剂,传统药物疗法起效慢,病程长。近年来的研究显示,小功率氦氖激光照射可对组织产生生物刺激作用,改善血液循环,促进伤口愈合及组织修复。因此,我科室对2012年1月-2012年10月门诊就诊的疱疹性口炎患儿采用氦氖激光辅助治疗,现将治疗效果报道如下。
