[Application of special acupoints for chronic gastritis in ancient literature of acupuncture and moxibustion].

The application of special acupoints for different primary symptoms of chronic gastritis in ancient literature of acupuncture and moxibustion was analyzed and summarized. With keywords, electronic and manual retrieval of ancient literature being performed to establish a database, the association rules were performed with SPSS Modeler 18. As a result, ① among all the 2243 items included, 109 items mentioned special acupoints (excluding those only mentioned crossing acupoint). The frequency of special acupoints was 2554 (71.7%), and the special acupoints on the spleen meridian, the stomach meridian, the conception vessel were frequently used. The frequency of five-shu point was highest, followed by front-mu points. ② The special acupoints for four main primary symptoms of chronic gastritis, "stomachache" "vomiting and regurgitation" "belching and acid regurgitation" and "epigastric fullness", included Zusanli (ST 36), Neiguan (PC 6), Zhongwan (CV 12), Gongsun (SP 4), Taibai (SP 3). In addition, the back-shu points were also selected to treat the primary symptoms other than "epigastric fullness". Zhangmen (LR 13) was added to treat "belching and acid regurgitation". The combination of Neiguan (PC 6) and Gongsun (SP 4) showed the strongest correlation; due to different primary symptoms, the combination had different emphasis.

[Extraction of rape seed proanthocyanidin with ultrasonic wave].

Rape seed proanthocyanidin was extracted by ultrasonic technology, and the conditions of extraction were studied. The results showed that the order of the factors which influenced the extraction effects were as follows: ethanol concentration, extracting temperature, ultrasonic extracting time and the ratio of the quantity of raw material to extraction agent (w/v). The optimal conditions were as follows: temperature: 60 degrees C, extracting agent: 60% ethanol aqueous, the ratio of the quantity of raw material to extracting agent: 1 : 20 (w/v), extracting number: 3 times, extracting time: 20 min, respectively. The yield of proanthocyanidins extracted by ultrasonic technology was 84.5% higher than traditional method. Rape Seed was rich in proanthocyanidin.
