BACKGROUND:Currently, transplantation of bone marrow mesenchymal stem cel s into the spinal cord is very limited to the recovery of animals fol owing spinal cord injury. Methylcobalamin is a common drug for the treatment of neurological diseases and injuries, but its effects on bone marrow mesenchymal stem cel s are unclear. OBJECTIVE:To study the feasibility of bone marrow mesenchymal stem cel s differentiating into neuron-like cel s induced by methylcobalamin in vitro and to observe the cel viability and proliferation of differentiated cel s. Methods:Rat bone marrow mesenchymal stem cel s were isolated, cultured and purified by density gradient centrifugation and adherent culture. The fourth to fifth generation of bone marrow mesenchymal stem cel s were treated for 24, 48 and 72 hours with different concentrations (25, 50 and 100 mg/L) of methylcobalamin. The morphological changes and cel growth were continuously observed under an inverted phase constract microscope. The viability of induced cel s was detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. The expressions of Nestin and neuron-specific enolase were identified by reverse transcription PCR and western blot. RESULTS AND CONCLUSION:Most of bone marrow mesenchymal stem cel s could differentiate into neuron-like cel s after induction with methylcobalamin. The expressions of Nestin and neuron-specific enolase were up-regulated after 48 hours of methylcobalamin treatment at different concentrations, especial y after treatment with 100 mg/L methylcobalamin. Similarly, the expressions of Nestin and neuron-specific enolase could be increased significantly after 100 mg/L methylcobalamin treatment for 24, 48 and 72 hours, especial y for 72 hours. It is indicated that methylcobalamin can induce bone marrow mesenchymal stem cel s differentiating into neuron-like cel s, and the optimal concentration of methylcobalamin is 100 mg/L.

Objective To explore the clinical features diagnosis and treatment of left main coronary artery (LM) disease. Methods According to the results of coronary angiography,significant stenosis was defined as ≥50% stenosis. Isolated LM group had 9 patients (4.62%),one-vessel stenosis LM group 15 patients (7.69%),two-vessel stenosis LM group 53 patients (27.18%) and three-vessel stenosis LM group 118 patients (60.51%). Results 195 cases (6.74%) of LM stenosis were found. The incidence rate was low. 164 patients (84.1%) had unstable angina,and 125 patients (64.1%) had myocardial infarction. Coronary artery bypass surgery was performed in 57 patients (29.2%) and the angina disappeared in most of them (84.2%). Five patients received unprotected LM stenosis and angina disappeared in all. Conclusion LM stenosis has sever symptoms. Coronary angiography is the only way for diagnosis and CABG the best treatment. Unprotected LM stenosis is valuable for some patients.

OBJECTIVE: To observe the anti-inflammatory and analgesic effects of Yitieling Paste (YTLP). METHODS: YTLP and aspirin (as a control drug) were introduced to treat the edematous ears of mice induced by xylene and swollen toes of mice induced by carrageenin, and to relieve the pain in mice induced by heat and acetic acid. The swelling degree, pain threshold and body distortions were measured. RESULTS: The repression rates of the ear edema in groups of YTLP of high and low dosages and the aspirin group were 67.92%, 52.52% and 58.28%, respectively. The repression rate of the toe swelling in YTLP high dosage group was higher than that of the aspirin group, which was higher than that of the YTLP low dosage group. The results of analgesic effect of the three YTLP-treated groups showed that with the increase of dosage, the pain thresholds were higher and higher, and the body distortions were lower and lower. The pain thresholds of high and medium dosage YTLP groups were near to the aspirin group. CONCLUSION: YTLP possesses a strong anti-inflammatory and analgesic effect.

In hippocampus, numerous studies have shown that N-methyl-D-aspartate (NMDA) receptors are essential for the initiation of long-term potentiation (LTP), whereas the expression of LTP is primarily mediated by the phosphorylation of the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors and the increased insertion of postsynaptic AMPA receptors. However, in recent years there is also evidence that NMDA receptor channels contribute to the expression of LTP under physiological conditions. It was examined whether NMDA receptor channels contributed to the expression of LTP of C-fiber evoked field potentials in rat spinal dorsal horn by intravenous or spinal application of NMDA receptor antagonists after the establishment of LTP. It was found that MK 801 (a non-competitive NMDA receptor antagonist) at dose of 0.1 mg/kg (iv) had no effect on the spinal LTP and at the dose of 0.5 mg/kg depressed the LTP significantly. However, the inhibitory effect of MK 801 at higher dose (1.0 mg/kg)was not different from that produced by the dose of 0.5 mg/kg. The similar inhibitory effect on spinal LTP was also observed, when MK 801 was applied locally at the recording segments of spinal cord. To confirm the above results, a competitive NMDA receptor antagonist AP V was tested. Spinal application of AP V at a concentration of 100 μmol/L produced a stronger depression than at 50 μmol/L. When the concentration of AP V increased to 200 μmol/L, no further depression was observed. These results indicate that NMDA receptor channels are involved in the expression of LTP of C-fiber evoked field potentials in the rat spinal dorsal horn.
