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 study the relationship between the expressions of vascular endothelial growth factor-C (VEGF-C) and vascular endothelial growth factor receptor-2 (KDR) in cervical carcinoma and the formation of cervical cancer and lymph node metastasis.Methods We selected 72 cervical carcinoma tissues,their corresponding adjacent tissues and 36 normal cervical tissues which have been resected in the Maternal and Child Health Care Hospital of Baoji of Shaanxi Province from January 2010 to December 2013.The mRNA and protein expressions of VEGF-C and KDR were examined by semi-quantitative PCR and enzyme linked immunosorbent assay in these tissues.The relationships between the expressions of VEGF-C and KDR and the formation of cervical cancer and lymph node metastasis were analyzed.Results The mRNA levels of VEGF-C in 72 cases of cervical cancer tissues and its corresponding adjacent tissues were 4.67 ± 1.05 and 2.02 ± 0.65,which were significantly higher than those in normal cervical tissues (0.36 ± 0.06),with significant differences (t =2.247,P =0.025;t =1.379,P =0.027).The protein levels of VEGF-C in 72 cases of cervical cancer tissues and their corresponding adjacent tissues were 68.30 ± 17.10 and 48.20 ± 12.70,which were significantly higher than those in normal cervical tissues (18.40 ± 10.70),with significant differences (t =4.357,P =0.016;t =6.337,P =0.012).The mRNA levels of KDR in 72 cases of cervical cancer tissues and their corresponding adjacent tissues were 3.52 ± 0.95 and 1.92 ± 0.87,which were significantly higher than those in normal cervical tissues (0.72 ±0.36),with significant differences (t =3.127,P =0.023;t =1.214,P =0.028).The protein levels of KDR in 72 cases of cervical cancer tissues and their corresponding adjacent tissues were 47.20 ± 15.60 and 38.60 ± 11.30,which were significantly higher than those in normal cervical tissues (16.40 ± 9.40),with significant differences (t =3.667,P =0.020;t =0.986,P =0.032).The expression level of VEGF-C protein in 72 cases of cervical cancer tissues was not correlated with age (x2 =0.54,P =0.17),tissue type (x2 =0.34,P =0.25),depth of invasion (x2 =5.39,P =0.08),pathological grade (x2 =0.78,P =0.11),but was correlated with tumor size (x2 =22.34,P =0.02),clinical stage (x2 =32.14,P =0.01) and lymph node metastasis (x2 =15.58,P =0.03).The expression level of its receptor KDR was correlated with tumor size (x2 =13.78,P =0.04),tissue type (x2 =32.74,P =0.01),pathological grade (x2 =13.72,P =0.04),depth of invasion (x2 =10.27,P =0.04),clinical staging (x2 =20.25,P =0.02) and lymph node metastasis (x2 =19.52,P =0.02),but was not correlated with age (x2 =4.17,P =0.09).Conclusion The expression levels of VEGF-C and KDR are correlated with the growth,invasion and metastasis of cervical cancer,which are good indicators of the lymph node metastasis.

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.

OBJECTIVE To evaluate the cardiotoxicity of a widen-spectrum antineoplastic drug, gambogic acid, through quantitative multiple cellular phenotypic characterization. METHODS H9c2 cell line was used as a model with doxorubicin (Dox) and amiodarone (Ami) as positive controls, hypaconi?tine as negative control and 0.1% DMSO as normal control. An optimized protocol was established to identify the morphology and function of cell nuclei. The effect of drugs on cell viability, nuclear area (Hoechst33342), mitochondria mass (MitoTracker Deep Red) and cytoplasmic calcium ion mobilization (Rhod2 AM)was studied. EC50 and Z′values were calculated to evaluate the degree of toxicology and to estimate the precision and false-positive rate, respectively. RESULTS Dose-response analysis indicated that EC50 of Dox on cell viability, nuclear area, mitochondrial mass was 0.72, 0.014 and 1.21μmol · L-1, respectively. On the other hand, EC50 of Ami on the parameters of cell viability, nuclear area and mitochon?drial mass was 14.83, 6.72 and 4.54μmol·L-1, respectively with Z′value above 0.5. Hypaconitine decreased the SER ridge of mitochondria. Gambogic acid caused significant mortality of H9c2 cells and induced nuclear shrinkage as Ami did. The EC50 values of cell viability and nuclear area were 0.24 and 1.16 μmol · L- 1. Meanwhile,gambogic acid disturbed the mitochondrial function as indicated by the increased mitochondrial area (EC50=0.44 μmol · L-1), abnormal SER Ridge(EC50=0.99 μmol · L-1) and decreased mitochondrial mass(EC50=1.21 μmol · L- 1). Cellular calcium mobilization was lower than normal (EC50=0.41 μmol · L-1). CONCLUSION The EC50 values of positive controls calculated from our assessment are similar those reported in literature. A multi-parameter and simultaneous evaluation enables a comprehensive analysis of the morphology of nuclei and mitochondria of cardiomyocytes and a preliminary assessment of the mechanisms of toxicity.
