Post-operative chemother- eficial for patients with stage 2 colon cancer buy 100 mg celecoxib overnight delivery, apy and chemoradiotherapy, and pre-operative as discussed previously. Historically, most trials 130 TEXTBOOK OF CLINICAL TRIALS in adjuvant colon cancer have included patients treatment benefit in both subgroups of patients; with both stage 2 and 3 disease. The majority of the absence of a significant interaction implies patients in such trials have been stage 3 patients, that there is no evidence that the benefit of treat- and subset analyses within these trials have con- ment differs by patient subgroup. However, because the majority of patients in such trials have not been to demonstrate a different feature of subgroup stage 2, and because the prognosis for the stage analyses. The first trial, R-01, demonstrated a 2 patients is overall more favourable, with fewer significant benefit in terms of overall survival patient deaths and thus less statistical power, for the addition of chemotherapy following the individual studies have not shown consistent resection compared to no post-surgical treatment.

Treatment method: All three groups were administered as the basis of treatment Suo Quan Wan Jia Sang Piao Xiao (Reduce the Stream Pills plus Mantis Egg-case) cheap 100 mg celecoxib overnight delivery. This was composed of: Wu Yao (Radix Linderae) Yi Zhi Ren (Fructus Alpiniae Oxyphyllae) Shan Yao (Radix Dioscoreae) Sang Piao Xiao (Ootheca Mantidis) 62 Treating Pediatric Bed-wetting with Acupuncture & Chinese Medicine In addition, the supplement the spleen group was also adminis- tered Bu Zhong Yi Qi Tang (Supplement the Spleen & Boost the Qi Decoction) minus Dang Gui (Radix Angelicae Sinensis): Huang Qi (Radix Astragali) Gan Cao (Radix Glycyrrhizae) Dang Shen (Radix Codonopsitis) Ju Pi (Exocarpium Citri) Sheng Ma (Rhizoma Cimicifugae) Chai Hu (Radix Bupleuri) Bai Zhu (Rhizoma Atractylodis Macrocephalae). The supplement the kidney group was also administered Wu Zi Yan Zong Wan (Five Seeds Increase Progeny Pills) minus Che Qian Zi (Semen Plantaginis): Gou Qi Zi (Fructus Lycii) Wu Wei Zi (Fructus Schisandrae) Tu Si Zi (Semen Cuscutae) Fu Pen Zi (Fructus Rubi) The supplement the spleen and kidneys group used a combina- tion of the above three formulas. One packet of the above group- appropriate medicinals was decocted in water and administered per day to all three groups.

From The Treatment of Enuresis with Self-devised Ma Chang Long Mu Tang (Ephedra, Acorus, Dragon Bone & Oyster Shell Decoction) by Meng Xiang-min et al. Twenty-six cases presented a particular pattern of night- time enuresis and 14 cases did not. Treatment method: Ma Chang Long Mu Tang (Ephedra, Acorus, Dragon Bone & Oyster Shell Decoction) was composed of: Ma Huang (Herba Ephedrae), 5-10g Shi Chang Pu (Rhizoma Acori Tatarinowii), 10-20g calcined Long Gu (Os Draconis), 15-25g Mu Li (Concha Ostreae), 15-25g If there was kidney qi vacuity as evidenced by enuresis many times per night, cold limbs, aversion to cold, a pale tongue, and deep, forceless pulse, 15-25 grams of Shan Zhu Yu (Fructus Corni) and 20-30 grams of Huang Qi (Radix Astragali) were added. If there was liver channel damp heat as evidenced by scanty, yel- lowish urine, a bitter taste in the mouth, a red tongue with yellow fur, and a rapid pulse, 15-25 grams of Long Dan Cao (Radix Gentianae) and 10-20 grams each of Sheng Di (uncooked Radix Rehmanniae) and Mu Tong (Caulis Akebiae) were added. One packet of these medicinals was decocted in water until 200 milli- liters of medicinal liquid remained. This resulting liquid was taken in 50 milliliter doses after lunch and dinner. If the disease was not cured in one course, treatment was continued for another course. Study outcomes: Thirty-four cases were cured, four improved, and two got no 64 Treating Pediatric Bed-wetting with Acupuncture & Chinese Medicine improvement. Fourteen of these cases were cured and one case improved after just one course of treatment.

The shortest course of disease was one year, and the longest was 20 years.
