6.Traditional Chinese medicine intervention for stem cell transplantation in the treatment of cerebrovascular diseases
Chinese Journal of Tissue Engineering Research 2013;(49):8615-8620
BACKGROUND:Stem cells under appropriate conditions can be induced to differentiate into neuron-like cells. Chinese herbs can function in cellproliferation and differentiation.
OBJECTIVE:To investigate the interventional effects of traditional Chinese medicine on stem celltransplantation in the treatment of cerebrovascular diseases.
METHODS:Experimental studies concerning traditional Chinese medicine intervention for stem celltransplantation were retrieved and analyzed. Under specific conditions, stem cells can proliferate in vitro in a suspended or monolayer manner, and can be potential y induced to differentiate into neurons, oligodendrocytes and astrocytes, thereby providing basis for stem celltransplantation in the treatment of cerebrovascular diseases. We observed expressions of nestin, glial fibril ary acidic protein, and microtubule-associated protein expression for analysis of stem cellproliferation and differentiation.
RESULTS AND CONCLUSION:Baicalin or Astragalus saponin Ⅳ can stimulate stem cells to differentiate into nerve cells in vitro. Naomaitong or danshen combined with bone marrow mesenchymal stem celltransplantation can promote neurological recovery from cerebrovascular diseases in rats. Buyang Huanwu Decoction can significantly promote the proliferation of neural stem cells in the subventricular zone and neurological recovery after cerebral ischemia. Chinese herbs, such as Zhichan Decoction and Panax notoginseng, can promote survival of transplanted cells and prevent most cellapoptosis in the stem celltherapy for treatment of Parkinson’s disease. Therapy of benefiting qi and elevating yang or ginsenosides Rg1 combined with stem celltherapy can improve memory ability of dementia rats. Traditional Chinese medicine exerts a catalytic role in the stem celltherapy for cerebrovascular diseases.

Objective To evaluate the accuracy of the soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) and lipopolysaccharide binding protein (LBP) as diagnostic indices for neonatal serious bacterial infections (SBI). Methods A total of 171 newborns were enrolled in the study, and were classiifed into SBI group (including early-onset and late-onset), non-SBI group according to clinical manifestations, laboratory examinations and the time of disease onset. Serum sTREM-1, LBP and C-reactive protein (CRP) levels were measured. Receiver operator characteristic curve (ROC) was drawn, and the area under curve (AUC) was calculated. Each index was evaluated for the diagnostic value of neonatal SBI. Results The sTREM-1 and LBP levels were signiifcantly higher in SBI group than those in non-SBI group (P=0.000). The AUC of ROC for sTREM-1, LBP and CRP in early-onset SBI was 0.888, 0.839 and 0.706, respectively. The AUC of ROC for sTREM-1, LBP and CRP in late-onset SBI was 0.860, 0.865 and 0.705, respectively. Conclusions Both sTREM-1 and LBP are useful for the diag-nosis of neonatal SBI.

BACKGROUND:The appropriate choice of orthoses based on hemiplegic patient’s condition can improve motor function recovery in stroke patients.
OBJECTIVE:To review the motor function recovery of stroke patients with hemiplegia wearing different types of orthoses.
METHODS:Application of different types of orthoses in hemiplegic patients was reviewed through access to literature, as wel as effects of a variety of orthoses on the recovery of motor functions in hemiplegic patients.
RESULTS AND CONCLUSION:Orthoses can reduce limb muscle tension and muscle spasms, and improve motor function and overal daily living skil s in stroke patients with hemiplegia, which play a variety of roles, including stable support, fixed protection, correction of deformity and functional compensation. However, the long-term therapeutic effect of orthoses cannot be verified because of fewer cases, shorter time for therapeutic observation, and the lack of long-term fol ow-up. It is necessary to perform long-term fol ow-up for the verification of long-term efficacy of orthoses. Meanwhile, the appropriate timing for removal of orthoses needs further study.
