BACKGROUND:The currently published literatures about Tuina manipulation for lumbar disc herniation include clinical observations, retrospective study and summary of clinical experience, which have shortcomings in the study design, choice of cases and outcome measures. Reviews may enrol randomized and intended references, and has no analysis or evaluation on the quality of involved literatures, leading to the bias and subjective views.
OBJECTIVE:To research the application laws of Tuina manipulation for treating lumbar disc herniation through literature analysis within 10 years.
METHODS:The key words of“lumbar disc herniation, traditional Chinese medicine, Tuina, manipulation, massage, rehabilitation, poking channels, point pressing, palpating pressing, and finger pressing”in Chinese were used to search the literature about Tuina manipulation in treatment of lumbar disc herniation within recent 10 years published in the Wanfang database, Vip database and CNKI database. The top 20 manipulations of Tuina for lumbar disc herniation were and statistical analyzed with hierarchical clustering statistical method.
RESULTS AND CONCLUSION:The hierarchical clustering analysis results showed that, Tuina manipulations for lumbar disc herniation are as fol ows:(1) manipulations acted on soft tissue, including rol ing, holding, pushing and pressing;(2) manipulations acted on acupuncture point, including Urinary Bladder Meridian of Foot-Taiyang acupuncture points (Shengshu, Dachangshu, Guanyuanshu, Zhibian, Chengfu, Weizhong, Chengshan and Kunlun), Gal Bladder Meridian of Foot-Shaoyang acupuncture points (Huantiao and Yanglingquan), Yaoyangguan point in Du Meridian, Zusanli point in Stomach Meridian of Foot-Yangming, and tender points;(3) manipulations acted on human bones and joints, including waist inclined pul method, waist back-stretching method, pelvic traction method and straight-leg raising method. The findings indicate that the potential application laws of Tuina manipulation for treating lumbar disc herniation are given priority to pressing acupuncture points (Urinary Bladder Meridian of Foot-Taiyang acupuncture point, Gal Bladder Meridian of Foot-Shaoyang acupuncture point, Du Meridian, Stomach Meridian of Foot-Yangming acupuncture point and tender points), at the same time companied with manipulations acted on soft tissue (rol ing, holding, pushing spinal method), and bones and joints (waist inclined pul method, waist back-stretching method, pelvic traction method and straight-leg raising method).

In order to establish a method for the determination of the sterols of the oil in the freeze-dried acai (Euterpe oleracea Mart.) and to evaluate its antioxidant activities, a saponification/extraction procedure and high performance liquid chromatography (HPLC) analysis method were developed and validated for the analysis of phytosterols in PEE (Petroleum ether extract). Separation was achieved on a Purosper STAR LP C18 column with a binary, gradient solvent system of acetonitrile and isopropanol. Evaporative light scattering detection (ELSD) was used to quantify β-sitosterol and the total sterols. Peak identification was verified by retention times and spikes with external standards. Standard curves were constructed (r = 0.999 2) to allow for sample quantification. Recovery of the saponification and extraction was demonstrated via analysis of spiked samples. The highest content of total sterols is β-sitosterol. The antioxidant activities of the extracts were evaluated using the total oxyradical scavenging capacity assay (TOSC assay). The result showed that the PEE exhibited significant antioxidant properties, sample concentration and the antioxidant capacity had a certain relevance.

Background Peripheral refraction of retina brings about influence on myopia development,and different corrective methods will play different roles on the peripheral refraction.Objective This study was to measure the peripheral refraction with progressive addition lenses (PALs) and single-vision spectacle lenses (SVLs) corrected in adolescent myopic eyes and to investigate the difference between them.Methods This was a selfcontrolled cross-sectional study.Forty corrected myopic eyes with PALs were recruited for the study.Twenty-three male and seventeen female subjects aged 10-15 years (mean 12.54 years±1.45 years) enrolled in this study.The refractive errors of the subjects ranged form-1.50 D to-6.00 D (mean-3.74 D±1.09 D) and the astigmatism was less than-1.50 D with the corrected visual acuity at least 20/25.1％ Tropicamide eye drops was topically administered for the cycloplegia and then Grand Seiko WAM-5500 Auto-refractor was used to measure the peripheral refraction.The measured points were determined follows as:fovea (0°),peripheral temporal (T30°,T20°,T10°) and nasal (N30°,N20°,N10°) visual fields from the right eyes.The mean of the six measuring points for each position was calculated.Peripheral refraction was measured from each subject under the wearing of PALs or SVLs (randomly in succession),and the statistic analyse perimeters included M value,relative peripheral refractive error (RPRE),J45,J180.Written informed consent was obtained from each subject before examination.Results The corrected visual acuity was 4.98 ± 0.65 and 4.97 ± 0.53 under the PALs and SVLs conditions respectively,showing in significant difference between them (t =0.222,P =0.639).Hypermetropic shift in peripheral M value and RPRE value were found with the increase of visual angle field,in contrast,the peripheral J180 showed a myopic shift,and significant difference was found among the six peripheral points with all of the above three perimeters (P＜0.05).Negative J45 values in the temporal visual filed and positive J45 values in the nasal filed showed less shift.Some peripheral angles of the peripheral refractions in M value,RPRE value,J180,J45 showed significantly difference from the fovea refraction(P＜0.05).Compared with SVLs correction,PALs induced relatively myopic shifts in M value and RPRE value in all of the peripheral angle fields,showing significant differences(P＜0.05).Conclusions PALs causes relatively myopic shift at the peripheral retina in adolescent myopic eyes in comparison with SVLs,and the important parameters are M value and RPRE value.The effect of PALs on controlling the onset and progression of myopia may be interpreted by peripheral refraction.
