ABSTRACT
This paper summarized LI Yuanwen's clinical experience in treating children with atopic dermatitis. It is considered that the core pathogenesis of children's atopic dermatitis is liver constraint and spleen deficiency， for which the main treatment methods are soothing the liver and fortifying the spleen， regulating blood and extinguishing wind， and self-made Jiawei Guomin Decoction （加味过敏煎） can be used. In clinical practice， children with atopic dermatitis are mainly divided into six types including heart fire hyperactivity， blood heat and exuberant toxin， damp pathogen congestion， disharmony of spleen and stomach， blood deficiency and wind-dryness， and yang deficiency and blood stasis. Jiawei Guomin Decoction with modifications in accordance with differentiated syndromes is recommended together with external used Qingshi Zhiyang Ointment （青石止痒软膏）.
ABSTRACT
Objective To study the feasibility and value of magnetic resonance diffusion tensor imaging (DTI) to monitor non?arteritic anterior ischemic optic neuropathy (NAION). Methods Thirty eight NAION patients (56 eyes) were divided into acute period in 17 eyes, progressive period in 16 eyes and chronic period in 23 eyes at the base of onset time. According to matching principle, 56 eyes in 38 normal controls (NCs) were enrolled. All the patients and NCs underwent MR and DTI scan. The raw data were processed by two experienced radiologists, mean diffusivity (MD), axial diffusivities (λ//), radial diffusivities (λ┴), fractional anisotropy (FA) and Length value were got. The independent sample t test was used for the parameter values between the NAION group and the NCs group. A single factor variance analysis was used to compare the parameters among different stages of NAION group. Results Compared to the NCs group, the values of FA and Length in NAION group were reduced [0.20±0.11 vs 0.31±0.12, (5.85±0.92) vs (65.11± 6.89) mm], and the differences were statistically significant (t=-4.28,-5.25;P<0.05). The values of MD andλ┴were increased [(0.16±0.04)×10-3 vs (0.10±0.04)×10-3 mm2/s, (0.16±0.05)×10-3 vs (0.09±0.03)×10-3 mm2/s] in NAION group and the differences were statistically significant (t=6.83, 7.10;P<0.05). The value of FA and Length in acute period, progressive period and chronic period of the NAION group decreased differently compared to the NCs group. At the same time, the value of MD value and λ┴in the three periods of the NAION group increased compared to the NCs groupand the differences were statistically significant (P<0.05). The value of FA between the acute period, the progressive period, and the chronic period of NAION group were statistically signficant (F=10.88, P<0.05). However, no significant differences were found in the values of MD, λ┴and Length of the NAION group (F=0.23, 0.64, 0.33, 1.38;P=0.79, 0.54, 0.72, 0.27). Conclusion The parameters of DTI can be used to monitor the damage of optic nerve and development in NAION.
ABSTRACT
70%). Based on the degree of coarctation, they are divided into two groups, one is mild grade (the circumference of isthmus is 0.5～0.8 cm, the ratio of ascending aorta and the aortic isthmus is 30%～ 45%), another is severe grade (the circumference is less than 0.5 cm, the ratio
