Semen Ziziphi spinosae ( SZS) , as a commonly used traditional Chinese medicine in clinic for insomnia therapy, is rich in pharmacological active ingredients such as saponins, flavonoids, alkaloids, oil and the other chemical compounds. The recent stud-ies indicated that some active ingredients in SZS exhibited a variety of activities including sedative hypnotics, antianxiety and anti-de-pression by regulating particular neurotransmitters such as 5-hydroxytryptamine (5-HT), gamma-amino butyric acid (GABA), norepi-nephrine, dopamine and glutamate. In accordance with the previous studies on pharmacological activities of SZS, this paper summa-rized and reviewed the applications of SZS in the treatment of central nervous system diseases, myocardial diseases and hepatic disea-ses, which might provide solid evidence for the application development of SZS.

Objective:To evaluate the safety, feasibility and operational performance of self-developed medical disposable portable endoscopy (YunSendo) for upper gastrointestinal endoscopy examination in Ba-Ma mini-pigs.Methods:A total of 10 Guangxi Ba-Ma mini-pigs were used in the experiment, and mucosal injury models were established in advance by biopsy forceps in esophagus, stomach, and duodenum. Each experimental animal underwent medical disposable portable endoscopy and Olympus endoscopy (GIF-Q260J) performed by two endoscopists separately. The time when the endoscope reached the duodenum, the number of detected mucosal injuries and endoscopic pictures of different parts with standard image acquisition were recorded. Endoscopic operational performance and endoscopic image quality were evaluated. Different endoscopists recorded experimental results with blind method. The procedures of the two endoscopic examinations were performed by coin-tossing method. The paired t test was used for statistical analysis. Results:There were no statistically significant differences in the insertion time and total operation time between medical disposable portable endoscopy and Olympus endoscopy ( (171.00±9.96) s vs. (164.00±17.84) s, (285.00±33.94) s vs. (273.40±23.46) s; t=1.289 and 1.281, P=0.230 and 0.232). There were no statistically significant differences in the percentage of time of clear visual field during endoscopy insertion and total operation between medical disposable portable endoscopy and Olympus endoscopy ((91.83±1.85)% vs. (91.52±1.51)%, (93.07±3.10)% vs. (92.06±2.57)%; t=0.401 and 0.689, P=0.698 and 0.508). Moreover, there were no statistically significant differences in the score of comprehensive operation performance, score of clear image number, score of image color recognition, score of image illumination, comprehensive score of image quality and number of detected mucosal injuries ((9.66±0.30) points vs. (9.86±0.15) points, (39.50±0.71) points vs. (39.30±1.06) points, (39.70±0.48) points vs. (39.40±0.70) points, (39.40±0.70) points vs. (39.50±0.71) points, (9.88±0.09) points vs. (9.85±0.20) points, 9.80±0.42 vs. 9.90±0.32; t=2.176, 1.000, 1.152, 0.317, 0.629 and 0.557, all P>0.05). There were no adverse events after operation in medical disposable portable endoscopy group and Olympus endoscopy group. Conclusions:The medical disposable portable endoscopy is safe and feasible for endoscopy examination in live animal models. Different parts of upper gastrointestinal tract and mucosal lesions can be clearly detected. The operational performance and the image quality are excellent, which is similar to Olympus endoscopy (GIF-Q260J).
