BACKGROUND:It is unclear whether serial cel passage in vitro influences the differentiation of bone marrow mesenchymal stem cel s into neural stem cel s.
OBJECTIVE:To investigate the effect of cel passage on the differentiation of bone marrow mesenchymal stem cel s into neural stem cel s.
METHODS:Rat bone marrow mesenchymal stem cel s were isolated and cultured by the whole bone marrow adherence method. Bone marrow mesenchymal stem cel s at passages 3, 6, 9, 12 were incubated in serum-free medium. After culture for 7 and 14 days, cel biological characterization was observed and differenitaiton ability into neural stem cel s was observed by detecting Nestin expression in cel s using flow cytometry. Then, the cel s were further induced to differentiate and cel multipotential differentiation capacity was detected by measurement of nerve enolase and glial acidic protein expression.
RESULTS AND CONCLUSION:Under induction, bone marrow mesenchymal stem cel s at different passages were al differentiated into Nestin-positive neural stem cel s. However, there was a significant difference in differentiation proportion of cel s at different passages (P<0.05). Strongest differentiation ability was found in the passage 6 cel s, with the Nestin expression up to (93.7±2.3)%at 7 days of induction and (96.2±1.8)%at 14 days of induction. The proportion of differentiated cel s at passages 6 and 9 was signfi cantly higher than that at passages 3 and 12. Moreover, adherent cel s were positive for nerve enolase and glial acidic protein. Al these findings indicate that the differentiation of bone marrow mesenchymal stem cel s into neural stem cel s is correlated with cel passage. Cel s at lower or higher passages are both detrimental to cel differentiation.

Objective:To observe the therapeutic effect and safety of warfarin on patients with atrial fibrillation. Methods:A total of 126 patients with atrial fibrillation from our hospital during Jun 2012-Jun 2013 were selected. According to hiding number random method,they were divided into aspirin group (n=63)and warfarin group (n=63).Coagulation function,blood lipid levels and end-point events were compared between two groups.Results:Compared with aspirin group,after treatment,there were significant reductions in levels of total cholesterol [(5.8 ±0.5)mmol/L vs.(5.2±0.7)mmol/L],triglyceride [(2.6±0.4)mmol/L vs.(2.4±0.3)mmol/L]and low density lipoprotein cholesterol [(2.7±0.5)mmol/L vs.(2.4±0.3)mmol/L],significant rise in level of high den-sity lipoprotein cholesterol [(1.1±0.2)mmol/L vs.(1.3±0.2)mmol/L],prothrombin time [(28.3±11.7)s vs. (36.9±10.4)s]and it′s international normalized ratio [(1.9±0.4)vs.(2.4±0.5)]in warfarin group,P <0.05 all.Incidence rate of endpoint events such as cerebral infarction and peripheral artery embolism etc.in warfarin group was significantly lower than that of aspirin group (3.17% vs.23.81%,P <0.01).The incidence rates of complications were 23.81% and 26.98% in warfarin group and aspirin group respectively,and they had no signifi-cant difference,P >0.05. Conclusion:For atrial fibrillation,the therapeutic effect and safety of warfarin is better than that of aspirin,is worth extending.

Objective To analyze the influence of hyponatremia on hospitalization days and hospital mortality of hospitalized patients with chronic heart failure. Methods All data were collected from 2465 patients with chronic heart failure in our hospital between January 1980 and August 2007. According to the admission serum sodium, all the patients were divided into two groups: low serum sodium group (Na+<135 mmol/L) and normal serum sodium group (Na+≥135retool/L). Clinical characteristics, therapeutic conditions and the influence of hyponatremia on prognosis were analyzed between the two groups. Results There were 618 patients in low serum sodium group among 2465 cases. Patients with hyponatremia were more likely to have lower systolic blood pressure and lower left ventricular ejection fraction. Lower admission serum sodium was related with higher concentration of serum angiotensin, aldosterone and higher activity of serum renin. Patients in low serum sodium group had significantly longer hospitalization days (Z=-4.026, P<0.01) and higher rate of hospital mortality (χ2=76.935, P<0.01) than patients in normal serum sodium group. Multivariate logistic regression indicated that lower admission serum sodium was an independent risk factor for hospitalization days (b= 0.928, P<0.01) and hospital mortality (OR=0.928, P<0.01). There was a negative correlation between admission serum sodium and hospitalization days (r=-0.132, P<0.01), and the rate of hospital mortality increased by 24.7for each 3 mmol/L decrease in admission serum sodium level. Conclusions Hyponatremia in hospitalized patients with chronic heart failure is relatively common and is associated with poorer heart function, higher activity of neural hormone and more severe prognosis. It is important to prevent hyponatremia for shortening hospitalization days and improving the prognosis of patients with chronic heart failure.

OBJECTIVEBy using orthogonal design method to optimnize prescription of pulsed electric field at Jiaji (EX- B 2) points for spinal cord injury (SCI).

METHODSFifty six patients of SCI were selected, in which 36 cases were divided into orthogonal design trial and 20 cases were into clinical verification. With 36 patients who received orthogonal design trial, Frankel grading scale was used as observation index to screen optimal prescription of pulsed electric field. Pulse frequency (factor A) included low frequency (factor A(I), 10(2) Hz). moderate frequency (factor A(II), 10(4) Hz) and high frequency (factor A(III), 10(3) Hz); pulse amplitude (factor B) included 0-30 V (factor B ), 0-60 V (factor B(II)) and 0-90 V (factor B(III)); pulse width (factor C) included 0.1 ms (factor C(I)). 0.6 ms (factor C(II)) and 0.9 ms (factor C(III)); acupuncture time (factor D) included one month (DI), three months (D(II)) and five months (D(III)). Twenty patients were used for clinical efficacy observation and the effects of screened optimal pre scription of pulsed electric field at Jiaji (EX-B 2) points combined with regular rehabilitation training on spasm se- verity, score of sensory and motor functions, Barthel index and Frankel score were observed.

RESULTS(1) As results of orthogonal design trial, the optimal prescription was A(III) B(III), C(I), D(III), which were high frequency (10(3) Hz), 0-90 V of pulse amplitude, 0.4 ms of pulse width and 5 months of treatment time. (2) As results of 20 patient clinical verification, Ashworth score, tendon reflex and clonus were all significantly improved (P<0.001, P<0.01), the scores of sensory and motor functions were evidently improvedtl (P<0.001, P<0.05), and Barthel in dex and Frankel score were also enhanced (P<0.001, P<0.05).

CONCLUSIONThe optimal prescription of pulsed electric field at Jiaji (EX-B 2) points for spinal cord injury is high frequency (10& Hz), 0-90 V of pulse amplitude, 0.4 ms of pulse width and 5 months of treatment time. The optimal prescription of pulsed electric field at Jiaji (EX-B 2) points combined with regular rehabilitation could obviously improve spasm severity, enhance senso- ry and motor functions, and ameliorate activity of daily life and Frankel score.
