目的 探讨1~ 6个月婴儿母亲饮食结构以及婴儿喂养方式两者与湿疹发病的关系,并观察对进食敏感食物母亲进行饮食干预治疗婴儿湿疹的疗效。方法 采用问卷方式调查705例婴儿母亲饮食结构及其婴儿的喂养方式,根据婴儿喂养方式不同分为纯母乳喂养组和纯人工喂养组,对纯母乳喂养组根据母亲哺乳期饮食结构,分为进食大量敏感食物组和进食少量敏感食物组以及非敏感食物组,比较不同喂养方式以及母亲不同饮食结构婴儿湿疹的患病率以及不同组别湿疹发病的相关性分析;并对进食敏感食物组湿疹患儿的母亲进行饮食干预,观察治疗效果。结果 广州地区纯母乳喂养婴儿湿疹患病率高于纯人工喂养组(P＜0.05),母乳喂养组中母亲进食敏感食物发病率高于非敏感食物(P＜0.001),进食敏感食物与湿疹发病率呈正相关关系(r=0.36)。对进食敏感食物母亲进行饮食人工干预后,婴儿湿疹患病率下降(P＜0.001)。结论 母亲进食敏感食物可能是婴儿湿疹高发的原因,对母亲进行饮食干预可有效减少婴儿湿疹的发病。

Objective Infantile eczema are possibly related to the feeding patterns and mother's dietary structure.The study in this paper is to investigate the relationship between them and evaluate the effect of diet intervention in breast feeding mother whose baby with eczema. Methods Infants were divided into 2 groups according to their feeding patterns:simple artificial feeding group and simple breast feeding group.In the simple breast feeding group,mothers were also divided into 3 levels according to their dietary structure.Mothers who ate a lot of allergenic food a day might get a dietary intervention.Prevalence rate of eczema was investigated and analyzed in each step. Results Simple breast feeding group had a higher eczema morbidity than simple artificial group(P＜0.05).The more allergenic food the mother ate,the higher occurrence of eczema of their babies(P＜0.001),which showed a positive correlation(r=0.36).The occurrence of eczema dropped significantly compared to the non intervention group(P＜0.001). Conclusion Mothers who are eating allergenic food is considered to a risk for infant's eczema. Food intervention is an effective method to reduce the prevalence rate.

Objective The aim is to investigate the effect of ambroxol on radiation lung injury and the expression of transforming growth factor β1(TGF-β1),and tumor necrosis factor α(TNF-α)in plasma. Methods Ninety-eight patients with locally advanced lung cancer in radiotherapy were randomized into treatment and control groups.Patients in the treatment group took ambroxol orally at a dosage of 60 mg,three times per day for 3 months from the beginning of radiotherapy.The expression of TGF-β1 and TNF-αin plasma was analyzed.The clinical symptoms and lung diffusing capacity were monitored using high resolving power computed tomography. Results The level of TGF-β1 in the control group was increased(11.8 ± 5.5 ng/mL),whereas in ambroxol-treated patients,the increase was not significant(5.5 ± 2.6 ng/mL,P＜0.001). Radiotherapy-induced elevation of TNF-α levels,seen in control patients,was also abolished after treatment with ambroxol(5.1 ± 1.3 vs 2.6 ± 0.8 ng/mL,P＜0.001). Conclusion Ambroxol can obviously decrease the plasma TGF-β1 and TNF-α levels after radiotherapy,and decrease the chances of early radiation pneumonitis and late pulmonary fibrosis,and improve treatment effect and quality of life of patients.

Objective To explore the influence of vibroacoustic therapy on visual fatigue teenagers. Methods 72 visual fatigue teenagers were randomly and equally divided into the observation group and the control group. Both groups were accepted nursing in terms of the correction of eye habits, doing more sports and balanced diet, while the observation group was also accepted vibroacoustic therapy. After three months the conditions of these two groups in terms of visual fatigue were compared. Results After the intervention the degree of visual fatigue relief and the score of symptoms in the observation group were higher than those in the control group, and these differences have statistic significance (P＜0.05). Conclusion Vibroacoustic therapy can help visual fatigue teenagers to relax muscles of eyes, improve microcirculation, strengthen ciliary muscle contractile force, improve the regulatory function of iris ciliary and relieve visual fatigue.

Objective To investigate the effect of transcutaneous accupoint electrical stimulation (TAES) in enhancing upper limb function in subjects with stroke. Methods 37 subjects with first stroke were randomly assigned into 2 groups:TAES group(n=19) and placebo stimulation group(n=18). All subjects received the same standard rehabilitation. In the TAES group, Model KD-2A stimulator was applied with 0.2 ms pulses, at 100 Hz within the subject's tolerance level on the 4 acupuncture points (LI15, L I11, LI4, and SJ5) in the affected upper limb for 60 min, 5 days a week for 3 weeks; The time and the course of treatment of the placebo stimulation group were as well as the TAES group's, but no current output for each treatment. All subjects in the 2 groups received standard rehabilitation program. Measurements including Fugl-Meyer motor assessment (FMA-UE) and modified Barthel index(MBI) on affected side were recorded before treatment after 2 and 3 weeks' treatments. Results After 3 weeks treatments,the function scores on affected side of the two groups were improved significantly(P<0.05). And function scores of the TAES group were significantly improved than those of the placebo group (P<0.05). Conclusion Transcutaneous accupoint electrical stimulation significantly may improve the recovery of upper limb function.

目的 分析经直肠彩超引导下不同前列腺穿刺方式的阳性率及其相关因素,探讨安全的穿刺方案。方法 回顾性分析接受经直肠彩超引导下前列腺穿刺的701例患者临床资料,所有患者均接受系统性13点穿刺活检,并假设13点穿刺中减少前列腺中线3个穿刺点为10点穿刺术式,加之标准的6点穿刺术式。比较上述穿刺术式的阳性率,分析T-PSA、前列腺体积、PSA体积密度(PSAD)、有无前列腺结节对穿刺阳性率的影响。结果 随前列腺穿刺针数的增加,活检阳性率增高。同一穿刺方式,不同T-PSA组间、不同前列腺体积组、不同PSAD组阳性率有差异。T-PSA>100 ng/mL时,三种穿刺方式的阳性率无差异;T-PSA<100 ng/mL时,6点穿刺法阳性率较低,而10点穿刺、13点穿刺阳性率无差异。前列腺体积>80 mL时,不同穿刺法阳性率有差异。PSAD<0.5 ng/mL²时,10点、13点穿刺阳性率无差异。结论 前列腺穿刺活检阳性率随穿刺针数增多而增加,可根据PSA水平、前列腺体积、PSAD选择个体化穿刺方案。
