Clinical observation on Governor Vessel-unblocking and brain-refreshing scalp acupuncture for cerebral palsy complicated with intellectual disabilities

Objective

To observe the clinical efficacy of Governor Vessel-unblocking and brain-refreshing scalp acupuncture for cerebral palsy (CP) complicated with intellectual disabilities.

Methods

A total of 300 CP cases aged between 1 and 5 years were randomly allocated into a treatment group (n=150) and a control group (n=150). Patients in the treatment group were treated with Governor Vessel-unblocking and brainrefreshing scalp acupuncture combined with rehabilitation training, whereas patients in the control group received rehabilitation training alone. The Beijing Gesell developmental (Gesell) scale and gross motor function measure (GMFM) scale were used to assess the motor and intellectual development before and 3 months after the treatment. In addition, the head CT/MRI examination was applied to assess the brain nerve repair before and after the treatment.

Results

After the treatment, the total effective rate in the treatment group was 78.0%, versus 42.7% in the control group, showing a statistical significance (P<0.05). As for scores of five subscales in the Gesell scale, there were significant intra-group differences in the treatment group (all P<0.05); and the scores in the treatment group were significantly better than those in the control group (all P<0.05). As for scores of five dimensions in GMFM scale, there were significant intra-group differences in the treatment group (all P<0.05); and the scores in the treatment group were significantly better than those in the control group (all P<0.05). According to the head CT/MRI findings, the total effective rate was 73.3% in the treatment group, versus 62.0% in the control group, showing a statistical significance (P<0.05).

Conclusion

When used in combination with rehabilitative training, Governor Vessel-unblocking and brain-refreshing scalp acupuncture can significantly improve the clinical efficacy for cerebral palsy complicated with intellectual disabilities. It can also improve the patients’ motor function, intelligence and language ability.

     

含水量对川牛膝种子活力的影响及其抗老化机制分析

以川牛膝Cyathula officinalis种子为材料,通过高温高湿法进行人工加速老化,研究9个含水量对川牛膝种子活力的影响,并对不同含水量的抗老化机制进行了分析。研究结果表明,人工老化后,种子活力普遍有所降低;总体而言,含水量6.55%~4.78%的种子活力及抗老化能力相对较强,种子电导率值、POD活性、MDA含量升高幅度均较小,脱氢酶和SOD活性降低幅度亦较小;且在种子含水量5.77%时,未老化种子发芽试验各指标最高,人工老化和未老化的种子POD活性均最低,浸出液电导率较低,脱氢酶、SOD活性均最高,CAT活性亦较高。因此,在对川牛膝种子进行低温种质库保存时,为使其保持较高的活力和抗老化能力,应考虑将含水量降至接近(5.70±1)%。

ADAMTS4 and its proteolytic fragments differentially affect melanoma growth and angiogenesis in mice

The metalloproteinase ADAMTS4 (ADAMTS, a disintegrin‐like and metalloproteinase with thrombospondin motif)/aggrecanase‐1 is highly expressed in cartilage and has been implicated in human arthritis. Although abundantly expressed in many types of cancer, its role in cancer remains unknown. In this work, we demonstrate for the first time that full‐length ADAMTS4 and its catalytically more active N‐terminal 53 kDa autocatalytic fragment both promote B16 melanoma growth and angiogenesis in mice. In contrast, overexpression of its catalytically inactive E362A mutant or truncated fragments containing only the C‐terminal ancillary domains suppresses melanoma growth and angiogenesis under similar conditions. Structure–function mapping revealed that the single thrombospondin‐type 1 repeat domain is essential and sufficient for the antitumorigenic activity displayed by the catalytically inactive ADAMTS4 isoforms. Suppression of tumor growth and angiogenesis in mice is accompanied by a significant increase in tumor cell apoptosis, whereas tumor cell proliferation is not affected. Importantly, we identified and demonstrated the presence of novel proteolytic fragments of ADAMTS4 containing essentially only the C‐terminal ancillary domains in cultured cells, and also in human cancer tissues, coexisting with full‐length and catalytically active N‐terminal fragments. The contrasting functions toward tumor growth in mice by the wild‐type proteinase and its catalytically inactive mutant correlate with their contrasting influences on angiogenesis signaling pathway molecules in B16 melanoma in mice. Our results suggest a complex role for ADAMTS4 in cancer with the functional balance of protumorigenic and antitumorigenic isoforms likely to act as an important parameter in determining the net influence of this metalloproteinase on tumor growth in vivo.
