[A textual research on the spreading of Jin Gui Yu Han Jing].

Jin Gui Yu Han Jing(, The Jade Case Classic of the Golden Cabinet) and Shanghan Lun(, Treatise on Febrile Diseases) have similar contents but different names, and they were handed down after being collated by the Medical Records Bureau in 1066, the third year of the Northern Song Dynasty. At present, Jin Gui Yu Han Jing is Chen Shijie's edition in the Qing Dynasty. Chen Shijie got the manuscript of Song Dynasty from He Zhuo, a scholar of Qing Dynasty, then corrected it, and published it in 1717. By searching the citations from Jin Gui Yu Han Jing in medical works from 1066 to 1717, and dividing them into two categories: direct quotation and indirect quotation, so as to investigate the spreading situation of Jin Gui Yu Han Jing since Song Dynasty. According to this, it can be inferred that Jin Gui Yu Han Jing had not been found by doctors in Yuan and Ming Dynasties.

Functionalized bio-artifact fabricated via selective slurry extrusion. Part 2: Fabrication of ceramic dental crown.

Functionalized ceramic dental crown was successfully fabricated through selective slurry extrusion (SSE) based technique of solid freeform fabrication (also known as rapid prototyping). After sintering, the decomposed tourmaline powders were embedded in ZrO2 matrix. The far infrared emission properties of the ceramic dental crown were improved due to the increase of the numbers of infrared active bonds from tourmaline. This new dental restoration process presents potential to provide dental patients with functionalized artificial teeth, which benefits the body health by the way of emitting far infrared rays in ambient temperatures.

[Climbing-upward inhibition of Oncomelania hupensis by niclosamide combination].

OBJECTIVE: To develop a combination of molluscicide/insecticide with a good molluscicidal effect, especially an inhibitory effect on climbing-upward of Oncomelania hupensis. METHODS: Experiments on molluscicidal and snail-climbing inhibition effect of the combination of niclosamide and shachongding [(dimethylamine) trithacyclohexane hydrochloride] were conducted by immersion and spraying in laboratory. RESULTS: The combination of niclosamide (0.2 mg/L) and shachongding (0.1 mg/L) showed an inhibition of 92.67% of snails to climb up. There was no significant difference in molluscicidal effect between the combination (LC90 0.198 mg/L) and niclosamide alone (LC90 0.207 mg/L). CONCLUSION: The combination showed an effective inhibition on the climbing-upward of snails in water so as to improve the molluscicidal effect and reduce the cost of mollusciciding.
