This article proposes the "Efficacy Theory" hypothesis of the traditional Chinese medicines (TCMs): TCMs take effects and weaken toxicities through the additive effects of numerous effective forms (including their constituents or/and metabolites) on a same target, the synergistic effects based on the overall action of the additive effects on individual targets and their toxicities scattering effects. A TCM may include approximately 1000 constituents and each constituent may produce about 100 metabolites in vivo after oral administration. Numerous effective forms of incalculable constituents and their metabolites could work like a "army group" together. When the quantity of a specific target molecule is larger than the pharmaceutical molecules, the molecules of different kinds of effective forms could combine with the target molecules successively, to exert the additive effects. When the target molecules are mostly occupied ("target most spaces occupied"), this TCM begins to work. The additive effects maybe exert not only in concentration but also in a time order way, which gives a sustained efficacy of TCM. The additive effects and the toxicities scattering effects are resulted from the same effective groups and not identical toxic groups among different effective form molecules. The "toxicities scattering effect" can be used to explain the non-toxic TCMs, but not fit for toxic TCMs. The efficacy theory showed that the variety of constituents and metabolites may participate in the process of pharmacodynamic actions, including the additive effects, synergy effects and toxicities scattering effects, which may be useful for explaining and developing the characteristic advantage of the TCMs. The questions we need to study or confirm are as follows: What are the TCMs' pharmacodynamic substance basis and mechanism made up of Why are toxicities of most TCMs' smaller How is the TCMs' "Efficacy Theory" which reflects characteristic advantage of TCMs applied in the research and development of new drugs.

Objective To investigate the effect of local injection of Botulinum toxin type A(BTXA) on spasticity and function of the affected upper limb in stroke patients.Methods A total of 32 stroke patients were re- cruited and randomly divided into two groups:a BTXA group and a control group.All the patients had spasticity of upper limb muscles,which scored grade 2 to 3 with the Modified Ashworth Scale(MAS) ,and decreased elbow joint range of motion.The 16 patients in the BTXA group received BTXA injection in the biceps brachii muscles and flexor muscles of forearm on 10～15 points,while those in the control group did not.All the patients in both groups were treated with rehabilitation training techniques.The MAS,Fugl-Meyer upper limb function assessment and Barthel In- dex were employed to evaluate the changes of muscle tone,upper limb function and activity of living (ADL)perform- ance of the patients before injection and at 1st,2nd,6th 12th weeks after injection.Results The therapeutic effect between the BTXA group anti control group was significantly different in terms of biceps muscle tone,the scores of Fugl-Meyer upper limb function assessment and Barthel Index.Compared with preinjection,muscle tone was de- creased significantly and ADL performance was improved after injection in BTXA group.The effects of BTXA lasted more than 12 weeks.Conclusion Intramuscular muhipoint injection of BTXA was useful in reducing muscle spas- ticity,and was helpful for increasing motor ability of the affected upper limb and ADL performance of the stroke pa- tients.

Objective To observe the status of oxidative stress and activity of alkaline phosphatase(ALP) in rats exposed to high fluoride for the different periods and to analyze the effect of fluoride on the activity of ALP and oxidative stress in fluorosis rats. Methods Twenty-four Wistar rats were divided into control and high-fluoride groups according to their body mass, 12 rats in each group. The control group drank tap water(sodium fluoride concentrations < 1 mg/L), and high-fluoride group drank tap water containing sodium fluoride(sodium fluoride concentrations 221 mg/L). On a standard diet and water available ad hbitum, each rat was measured body weight once a week in 1,4,8,12 week. The biochemical techniques were used to test the indicators of oxidative stress including malonaldehyde(MDA), superoxidedismutase(SOD), glutathione peroxidase(GPx), uric acid and activity of ALP in serum of fluorosis rats. Results There was a interaction between fluoride and time in the activity of ALP (F = 4.690,P < 0.05). The activity of ALP was obviously higher in rats exposed to fluoride for 1,12 week [ (19.29± 3.69), (15.72 ± 0.79)kU/L] compared to the control[ (14.08 ± 1.99),(12.91 ± 3.97)kU/L, all P< 0.05] ; the level of MDA was obviously higher in rats exposed to fluoride for 1,4 week [ ( 13.37 ± 4.38 ), ( 11.82 ± 2.08) μmol/L ] compared to the respective control[ (8.75 ± 3.24), (7.42 ± 2.62)μmol/L, all P < 0.05]; difference of SOD and GPx between control and high-fluoride groups was not statistically significant(all P > 0.05); the level of uric acid in serum was significantly higher in high-fluoride group for 1,4 week[ (89.53 ± 13.21 ), (88.47 ± 19.78 )μmol/L] compared to the control [ (77.79 ± 11.43 ), (65.42 ± i 3.42) μ mol/L, all P < 0.05 ], but the level of uric acid showed lower in high-fluoride group for 8,12 week [(67.21 ± 9.44), (73.95 ± 9.52)μmol/L] compared to the control [(77.79 ± 11.43), (65.42 ± 13.42)μmol/L]. Conclusions Effect of overdose fluoride on ALP is time-dependant. On the other hand,overdose fluoride stimulates the status of oxidative stress in a way unrelated to the exposure period.
