Resource Value Discovery and Utilization of Wastes in Industrialization of Rhei Radix et Rhizoma / 中国实验方剂学杂志

The recycling of traditional Chinese medicine （TCM） wastes is an important research topic to be solved urgently in the industrialization of TCM resources. Rhei Radix et Rhizoma is a bulk Chinese herb mainly derived from Rheum palmatum，R. tanguticum，and R. officinale. At present，these three medicinal plants have been cultivated on a large scale and widely used in the fields of medicine，health care，food，cosmetics，and veterinary medicine，with an annual demand of more than 5 500 tons（1 ton=1 000 kg）. However，a large number of wastes such as non-medicinal parts and residues produced in the production and deep processing are discarded because there is no effective way of utilization，resulting in serious waste of resources and environmental pollution. The non-medicinal parts contain not only the chemical components and pharmacological effects similar to those of roots and rhizomes but also a variety of amino acids，mineral elements，and conventional nutrients. They have a long history of use，and the content of some resource components is higher than that in roots and rhizomes. In particular，their stems and leaves exhibit great potential to be consumed as food and medicine due to high safety. Besides，the content of anthraquinones in Rhei Radix et Rhizoma residue is high and it possesses good antibacterial activity. It can be seen that the waste from the industrialization of Rhei Radix et Rhizoma has high utilization value. Hence，based on the relevant literature and investigation on the application of producing areas in China and abroad，the paper summarized the utilization status of their medicinal and non-medicinal parts，the waste production in the industrialization，as well as the active substances and utilization ways and put forward the multi-level and multi-path utilization strategy of Rhei Radix et Rhizoma wastes，in order to provide reference for the rational development and application of Rhei Radix et Rhizoma resources and promote the effective utilization and green development of the corresponding wastes.

Quantification of acupuncture manipulation based on video motion capture / 医用生物力学

Objective To accurately measure the motion angels of hand-related joints during manipulations of acupuncture needle thrusting-pulling and twirling, so as to provide quantitative references for acupuncture manipulation. Methods Six acupuncturists with over 3-year acupuncture experience and one volunteer were enrolled in this study. The angles of the forearm, wrist, metacarpophalangeal & interphalangeal joints of the thumb and index finger in each acupuncturist when performing thrusting-pulling and twirling manipulation were measured by the video motion capture (VMC) system, and the different ranges of above-mentioned angles among the 6 acupuncturists when performing 10 trails of thrusting-pulling and twirling manipulations on the volunteer’s thigh were compared. Results There was no significant difference in the ranges of relevant hand-related angles in the acupuncturist (P>0.05). The manipulation of thrusting-pulling was mainly managed by the wrist joint, with the range of (7.23±1.87)°, while the manipulation of twirling was mainly managed by the interphalangeal joints of the index finger, and the range of the first and second interphalangeal joints of the index finger was (28.33±2.18)°and (10.43±1.69)°, respectively. Conclusions The VMC can be a reliable method to quantify the parameters of acupuncture manipulation. Different acupuncture manipulation shows particular variation of the joint angles, which can be used as a reference to quantify the acupuncture manipulation.

Study on needling depth and direction from different acupoints to sphenopalatine ganglion / 中国针灸

<p><b>OBJECTIVE</b>To observe and survey the location of Xiaguan (ST 7), "Die'e" and Quanliao (SI 18) on the surface, and the needling depth and direction from the 3 points to sphenopalatine ganglion.</p><p><b>METHODS</b>Fifteen corpses (30 sides) of adult male were fixed by 10% formalin. The lateral areas of face were dissected from the surface to the deep on the 3 acupoints: the electric drill with the kirschner wire punctured towards the sphenopalatine ganglion and extended to the contralateral areas according to different directions of puncturing sphenopalatine ganglion from the 3 acupoints. The corresponding puncturing points of the 3 acupoints were measured by the coordinate location method.</p><p><b>RESULTS</b>(1) Surface location: the distance between Quanliao (SI 18) and "Die'e" was 21 mm and the distance between Xiaguan (ST 7) and "Die'e" was 17 mm; (2) Inserting depth of each point to sphenopalatine ganglion: the depths of Xiaguan (ST 7), "Die'e" and Quanliao (SI 18) were 49.9 mm, 46.9 mm and 46.6 mm, respectively; (3) The coordinate location of the corresponding puncturing points: the puncturing direction of Xiaguan (ST 7) was anterointernal upper corresponding to the area of connecting center between contralateral Taiyang (EX-HN 5) and Tongziliao (GB 1), the distance between the corresponding inserting point of Xiaguan (ST 7) and Sizhukong (TE 23) was 17.6 mm; the puncturing direction of "Die'e" point was posterointernal upper, and the horizontal distance from the corresponding puncture point to the zygomatic arch was 33 mm and the vertical distance from the corresponding puncture point to the eyes' outer canthus was 42 mm; the puncturing direction of Quanliao (SI 18) was posteriointernal upper and the distance between the corresponding inserting point and the area of contralateral parietal tuber, the distance between the corresponding inserting point of Quanliao (SI 18) and the connecting line of bilateral external acoustic pore was 28 mm, the distance between the corresponding inserting point of Quan-liao (SI 18) and the medial line of the head was 62 mm.</p><p><b>CONCLUSION</b>Understanding the surface location, inserting depths and the general puncturing directions of the 3 points can provide basis for puncturing the sphenopalatine ganglion in clinical practice.</p>
