1. Acupoint Wei Zhong (UB 40) in Treating Chronic Low Back Pain

SUMMARY: 90 patients with chronic low back pain were ran- domly divided into treatment group and control group.All subjects met the diagnostic criteria of chronic low back pain according to Practical Surgery (Shi Yong Wai Ke Xue, 實用外科學), including: 1) pain in lumbar and sacral region triggered by organic lumbar condi- tions 2) low back pain not induced by abdominal or pelvic disease. Exclusion criteria includes: patients with severe osteoporosis, lumbar vertebral fracture/tuberculosis/tumor/disc slippage, complications of cardio-cerebrovascular or hematological disease, patients who were pregnant or breastfeeding, patients with severe psychological disease, congenital lumbar malformation or severe scoliosis confirmed by X- ray. Both groups were comparable in age, gender, disease course and severity of disease (P>0.05). Subjects in both groups received acu- puncture treatment at Shen Shu (腎俞UB 23) and Da Chang Shu ( 大腸俞UB 25). Subjects in treatment group also received acupunc- ture at Wei Zhong (委中UB40) bilaterally and subjects in the control group received acupuncture at sham Wei Zhong point located 1.5 cm medial to the actual Wei Zhong point.Treatment was 20 minutes once a day, 6 days per week for 2 weeks for both groups. Efficacy of treatment was assessed according to Visual Analogue Scale (VAS), and the severity of disease was considered as: a). Mild: if VAS was between 1-3; b). Moderate: if VAS was between 4-6; c). Severe: if VAS was between 7-10.

According to the result, both groups showed significant improve- ment in VAS after treatment; however, the improvement was more significant in the treatment group (P<0.05).Acupuncture treatment including Wei Zhong (UB 40) is effective in alleviating chronic low back pain, possibly due to its effect in repairing the muscular damage along the Urinary Bladder Meridian.

2. Discussion of Timing and Application of Qianzheng Powder In The Treatment of Peripheral Facial Paralysis

SUMMARY: Peripheral facial paralysis is also called as “Mian-Tan” (Face Paralysis or Bell’s Palsy) in Traditional Chinese Medicine and is most commonly seen in males in their 20-40s. There are four etiolo- gies of the disease according to Traditional Chinese Medicine: 1) Lack of Zheng Qi (正氣) leading to external pathogen invasion; 2) Wind phlegm congesting meridian; 3) Qi deficiency and Blood stagnation; 4) Internal Liver wind.As theYang-Ming (陽明) and Shao-Yang (少陽) meridians in the face become stagnated or malnourished, the Qi and Blood become stagnated, leading to the loosening of the facial mus- cle. Qianzheng Powder (牽正散) is a Traditional Chinese Medicine formula commonly used in treating facial paralysis. The ingredients of Qianzheng Powder includes Bai Fu Zi(白附子 Rhizoma Typhonii 6g), Jiang Can (僵蠶 Bombyx Batryticatus 6g), and Quan Xie (全蝎 Scorpio 3g). Bai Fu Zi has the flavor of pungent, nature of warmth, goes through Yang-Ming meridian, and possesses the function of ex- pelling wind, dispersing phlegm, and relieving convulsion; Therefore, Bai Fu Zi is the principle medicine in Qianzheng Powder. Quan Xie clears and unclog the meridians, and Jiang Can disperses phlegm and relieve convulsion. Qianzheng Powder is particularly effective when facial paralysis is caused by wind-phlegm congestingYang Ming merid- ian. There are 4 stages of peripheral facial paralysis. The first stage is called acute stage (1-7 days after onset), the second stage is a sub- acute stage (8-14 days after onset), the third stage is recovery stage (15-30 days after onset), and the fourth stage is recovery phase with complication, such as facial muscle spasm and contracture, mostly due to ineffective treatment in the first two stages or the weak con- stitution of the patient (eg. elderly). In the first stage, the main clinical symptoms include: unilateral facial muscle weakness, drooling, and difficulty speaking. In the second stage, symptoms from the acute stage are under control and progression is stabilized. Qianzheng is particularly effective in treating peripheral facial paralysis when ap- plied in the first and second stage, as the formula can expel exter- nal pathogen, disperse phlegm, clear meridian, extinguish wind, stop spasm, and dredge Qi and blood.
