[Discussion on the location of Dazhui (GV 14) and Yaoyangguan (GV 3)].

Since the anatomical location of acupoints was recorded in The latest Practice of Western Acupuncture in 1915, and Lecture Notes on Advanced Acupuncture in 1931, the Japanese acupuncture works of Chinese translation version, the location of Dazhui (GV 14) (under the spinous process of the 7th cervical vertebra) and Yaoyangguan (GV 3) (under the spinous process of the 4th lumbar vertebra) had rarely been questioned for nearly a century. In order to confirm the above statement, the writers have reviewed ancient literature, combined with the modern anatomical knowledge and searched the evidences from the core arguments of the acupuncture Mingtang chart and the bronze acupuncture statue. It is believed that Dazhui （GV 14） should be positioned under the spinous process of the 1st thoracic vertebra, and Yaoyangguan（GV 3） be under the spinous process of the 5th lumbar vertebra. Accordingly, all of the other acupoints of these meridians should be moved down by 1 vertebra, i.e. those on the governor vessel from Dazhui (GV 14) to Yaoyangguan (GV 3), those on the 1st lateral line of the bladder meridian of foot-taiyang from Dazhu (BL 11) to Baihuanshu (BL 30) and those on the 2nd lateral line of the bladder meridian from Fufen (BL 41) to Zhibian (BL 54).

[A pair of enantiomeric sesquiterpenoids from florets of Carthamus tinctorius].

This study investigated the chemical components from the florets of Carthamus tinctorius. Five compounds were isolated from C. tinctorius by column chromatography with silica gel and toyopearl HW-40 F, preparative thin-layer chromatography(TLC), and semi-preparative reverse phased high performance liquid chromatography(RP-HPLC). Their structures were identified by mass spectrometry(MS), one-dimension nuclear magnetic resonance(1 D-NMR), two-dimension nuclear magnetic resonance(2 D-NMR), and single-crystal X-ray diffraction as(-)-(2S,3S,5S,7S,10R)-eudesma-4(15)-en-2,3,11-triol(1 a),(+)-(2R,3R,5R,7R,10S)-eudesma-4(15)-en-2,3,11-triol(1 b), rosin(2),(+)-syringaresinol(3), and(E)-1-(4'-hydroxyphenyl)-but-1-en-3-one(4). Compounds 1 a and 1 b are a pair of enantiomeric sesquiterpenoids. Compound 1 a is a new eudesmene and is named(-)-plucheol A. Compound 1 a at 100 µmol·L~(-1) showed significant antioxidant activity against ABTS~(+·) and DPPH·, with the scavenging rates of 30.98%±4.17% and 27.52%±1.24%, respectively, while compound 1 b was inactive. In addition, compounds 1 a and 1 b showed no obvious anti-inflammatory activity.

[Roller compaction research of Banlangen effervsce tablets].

OBJECTIVE: To study the conditions and parameters of roller compaction of Banlangen effervsce tablet. METHOD: The experimentation adopts L9 (3(4)) orthogonal experiment to study the conditions and parameters of roller compaction of Banlangen effervsce tablet; studied factors that included roller pressure, roller speed and moisture content of power, which influence the result of granule yield and granule friability. RESULT: The optimal technique is: roller pressure at 1.5 MPa; roller speed at 15 Hz; moisture content of power at 1.5%. CONCLUSION: The study of roller compaction technique of Banlangen effervsce tablets provides some technicial consults of its research and production.
