Aerobic C-C Bond Cleavage of Allylic Alcohols via Co-Catalyzed Hydrogen Atom Transfer.

A simple, efficient method has been developed for the CoIII-H-catalyzed aerobic C-C bond cleavage of tertiary allylic alcohols to access ketones. This novel approach presents excellent chemoselectivity, good functional group compatibility, and high yields. This reaction occurs through a HAT-initiated peroxide intermediate, and an adjacent glycol-type diradical fragmentation process is recommended.

[Clinical effect of plum-blossom needle tapping at three yin meridians of wrist on wrist joint contracture after stroke].

OBJECTIVE: To compare the therapeutic effect of plum-blossom needle tapping at three yin meridians of wrist combined with rehabilitation training and simple rehabilitation training on wrist joint contracture after stroke. METHODS: A total of 72 patients with wrist joint contracture after stroke were randomized into an observation group and a control group, 36 cases in each one. In the control group, simple rehabilitation training was applied, 5 times a week, 3 weeks as one course and totally 3 courses were required. On the basis of the treatment in the control group, plum-blossom needle tapping at three yin meridians of wrist was adopted in the observation group. The tapping regions were wrist traveling parts of three yin meridians of hand, ranging from up 3 cun to below 1 cun of wrist crease, 3 times a week, 3 weeks as one course and totally 3 courses were required. The active range of motion (AROM) of active wrist extension, Fugl-Meyer score (FMA) and Barthel index (BI) score were observed before and after treatment in the two groups. RESULTS: The AROM, FMA scores and BI scores after treatment in the two groups were superior to before treatment (P<0.05), and the improvements of 3 indexes in the observation group were superior to the control group (P<0.05). CONCLUSION: The therapeutic effect of plum-blossom needle tapping at three yin meridians of wrist combined with rehabilitation training is superior to simple rehabilitation training on wrist joint contracture after stroke.

[Clinical observation on plum-blossom needle combined with rehabilitation training for hand spasm after stroke].

OBJECTIVE: To observe the effect difference between plum-blossom needle combined with rehabilitation training and conventional rehabilitation training for hand spasm after stroke. METHODS: A total of 61 patients were randomly divided into a comprehensive treatment group (30 cases) and a rehabilitation training group (31 cases). In the rehabilitation training group, Bobath occupational therapy, OT training, and hand function training were adopted, once every day; on the basis of treatment in the rehabilitation group, plum-blossom needle was applied at the lung meridian of hand-taiyin, heart meridian of hand-shaoyin, pericardium meridian of hand-jueyin in the comprehensive treatment group. The treatment was given once every two days, three weeks as one course in the two gnoups. After 3 courses of treatment, clinical efficacy evaluation was performed, and the modified Ashworth scale and Fugl-Meyer (FMA) motor function scores were assessed before and after treatment. RESULTS: After treatment, the grade for Ashworth scale and FMA scores in the comprehensive treatment group and the rehabilitation trainning group were better than those before treatment (all P<0.05), and the improvements in hand spasm and hand fuction in the comprehensive treatment group were superior apparently to those in the rehabilitation trainning group (both P<0.05) The total effective rate of hand function was 93.3% (28/30) in the comprehensive treatment group, which was better than 74.2% (23/31) in the rehabilitation training group (P<0.05). CONCLUSION: Plum-blossom needle combined with rehabilitation training are more effective than simple rehabilitation training for hand spasm after stroke.
