OBJECTIVE: To optimize the purification technique for the extract of Acanthopanax senticosus Harms. METHODS: The techniques of D- 101 macroporous resin adsorption, polyamide adsorption and n- butanol extraction were separately applied to purify the aqueous extract of Acanthopanax senticosus Harms. Syringin was detected by HPLC and total flavone was detected by UV. The anti- cerebral ischemia effects of three purified samples were compared using rat MCAO model and mouse decapitation gape model. RESULTS: The three purified samples all showed anti- cerebral ischemia effects, with the sample purified via D- 101 macroporous resin adsorption having stronger effects than the other two. The content of Syringin was correlated with anti- cerebral ischemia effects. CONCLUSIONS: D- 101 macroporous resin adsorption is a be-tter technique for purifying the aqueous extract of Acanthopanax senticosus Harms.

Objective To explore the research of Jianpi-Huatan decoction resisting the nude mouse MFC hepatic metastasis and its mechanism. Methods MFC cells inoculation in nude mice spleen, establishing nude mice hepatic metastasis model, which are divided into model group, 5-fu injection group, Jianpi-Huatan decoction high, medium and low dose group according to radom number table. Mice in high, medium and low dose Jianpi-Huatan decoction groups were adiminstrated with 80,40 and 20 g/kg Jianpi-Huatan decoction,in 5-fu groups were adiminstrated by intraperitoneal injection with 60mg/kg 5-fu injection and in model groups with Physiological saline once a day for 4 consecutive weeks. After the end, calculate the nude mice weight, spleen tumor weight and evaluation of hepatic metastases. And immune histochemical method and RT-PCR method is applied to detect tumor tissue of the expression of P53, Bcl-2 protein and mRNA. Results Compared with model group, Jianpi-Huatan decoction high and medium dose group can obviously increase body weight[(21.40 ± 1.43)g, (21.70 ± 1.02)g vs.(20.37 ± 1.17)g] and reduce the in situ tumor weight [(0.26 ±0.13)g,(0.16 ±0.05)g vs.(0.63 ±0.17)g]and the number of liver metastases;the mRNA levels of P53 and Bcl-2 (8.32 ±0.38,5.42 ±0.45,3.09 ±0.26 vs.9.67 ±1.31)and(4.65 ±0.61,3.22 ±0.21,2.49 ±0.19 vs.5.32 ±0.42) were decreased in low,medium and high dose Jianpi-Huatan decoction groups;P53(76.11 ±5.23,45.20 ±3.77, 23.11 ± 3.14 vs.81.63 ± 5.01)and Bcl-2(58.67 ± 5.27,32.00 ± 3.13,19.00 ± 2.54 vs.63.00 ± 4.10)levels were down-regulated in each dose of Jianpi-Huatan decoction group.Conclusions Jianpi-Huatan decoction can restrain nude mouse transplantation tumor growth and hepatic metastasis, which related to the cut of the expression of P53, Bcl-2 gene and protein.

Objective Aiming to develop a distance-adaptive visual function self-examination system based on tablet computers and evaluate its accuracy.Methods Utilizing ArUco technology on a tablet device equipped with the camera,a system was developed to assess visual functions by identifying QR codes within a 2-meters range for real-time ranging.This system integrates various visual function tests,including visual acuity test(conventional visual acuity test and high-pass visual acuity test with varying contrasts),accommodative amplitude test,and visual field test at the foveal(5°).A total of 22 healthy subjects(44 eyes)participated in visual function assessments,with 6 subjects undergoing visual acuity tests at varying distances(1 m,1.25 m,1.6 m,2 m)and accommodative amplitude tests under both refractive correction and simulated undercorrection of-3.00D.The program distance and actual distance were compared,the consistency of visual acuity outcomes for identical optotype at different distances were assessed,the accommodative amplitude under refractive correction and undercorrection were analyzed,the repeatability of accommodative amplitude outcomes was evaluated using Intraclass Correlation Coefficient(ICC),and the contrast threshold and efficacy of visual field test outcomes were analyzed.Results The program distance and actual distance showed good agreement.High-pass visual acuity tests with the same contrast showed no significant differences at different distances(P?>?0.05),while conventional visual acuity tests showed significant differences at distances of 0.9 to 1.1 meters compared to other distances(P?0.001).ICC of accommodative amplitude tests was 0.861(P?0.001).The accommodative amplitude was lower in the undercorrected state compared to refractive correction,with a statistically significant difference(P?0.05).The average extreme outlier of contrast threshold for binocular visual field was 16.92,and the program correctly identified visual field defects.Conclusion Based on a tablet computer,this study developed a distance-adaptive visual function self-examination system capable of precisely measuring distances up to 2 meters in real-time.It automatically adjusts the initial size of optotypes according to the distance to ensure accurate presentation.The system facilitates tests on visual acuity,accommodative amplitude,and central 5° visual field,offering flexibility of tests in various distance and enhanced test power,making it suitable for visual function tests in constrained environments like space stations where fixed distances are impractica.
