OBSERVATIONS ON THE THERAPEUTIC EFFECT OF THE TREATMENT OF 100 SCAPULOHUMERAL PERIARTHRITIS CASES BY "HEGUCI" (MUSCLE NEEDLING) COMBINED WITH MASSAGE

Objective： To explore an effective method for managing middle and late stages of scapulohumeral periarthritis. Methods： A total of 182 cases of scapulohumeral periarthritis were randomized into treatment group （100 cases） and control group （ 82 cases）; those in treatment group were managed by “Heguci” （合谷刺 muscle needling） at the reactionary spot of focus （found out via palpation around the shoulder region） in combination with reinforcing needling manipulation of “Setting the Mountain on Fire” and topical massage; whereas, those in control group treated by conventional method of “selecting aoupoints E Jianqian （肩前 extra point）, Jianyu （肩髃 LI 15）, Jianliao （肩髎 TE 14）, etc] along the course of the affected meridians in combination with massage”. The treatment was given once daily, with 10 sessions being a therapeutic course, 20 sessions altogether. Results： Of the 100 cases and 82 cases in control and treatment groups, 36 （43.90%） and 69 （69.00%） were cured, 42 （51.21% ） and 26 （26.00%） improved, 4 （4.87%） and 5 （5.00%） failed, with the total effective rates being 95.13% and 95.00% respectively. The average treatment sessions of control and treatment groups were 16.32±4.24 and 9.66±8.44 separately. The curative rate of treatment group was significantly higher than that of control group and the rumber of the therapeutic sessions required of the former group was evidently fewer than that of the later group （ P 〈 0.01 ）. Conclusion： The therapeutic effect of “Heguci” combined with massage is significantly superior to that of conventional acupuncture plus massage in the treatment of middle and late stages of scapulohumeral periarthritis.

Focusing of Intense Laser via Parabolic Plasma Concave Surface

Since laser intensity plays an important role in laser plasma interactions,a method of increasing laser intensity- focusing of an intense laser via a parabolic plasma concave surface- is proposed and investigated by three-dimensional particle-in-cell simulations.The geometric focusing via a parabolic concave surface and the temporal compression of high harmonics increased the peak intensity of the laser pulse by about two orders of magnitude.Compared with the improvement via laser optics approaches,this scheme is much more economic and appropriate for most femtosecond laser facilities.

Two approaches to three-dimensional array foci of generalized Fibonacci structures

We propose two technologies to extend the number of layers in order to complete the three-dimensional（3D）array diffraction-limited foci, which means there are two-dimensional array foci at multi-focal planes. One technology is the diffractive optical lever; the other is multi-hybrid Fibonacci structures. Based on the aperiodic Fibonacci structures and binary phase modulation, various kinds of devices can be designed to produce 3D array foci whose focusing properties approximately satisfy the mathematical characteristics of the Fibonacci sequences. With those technologies, the diffraction-limited array foci are freely designed or distributed as required at the desired multiple focal planes.
