ABSTRACT

Objective To explore the mechanism of icariin mediating migration of mesenchymal stem cells (MSC) in rat bone marrow. Methods MSC proliferation was detected by CCK-8 test. Cell apoptosis was examined with Hoechst33342 staining after the establishment of cellular oxygen and glucose deprivation model. The protein expressions of CXCR4, the receptor of SDF-1, in the surface of MSC after stimulated by icariin were detected through Western blot. The migration of MSC was observed by Transwell chemotaxis assay. Results 0.01μmol/L, 0.1μmol/L and 1μmol/L of icariin could significantly promote the proliferation of MSC, while 10μmol/L of icariin inhibited the proliferation of MSC. After treatment of oxygen and glucose deprivation in vitro, 0.1μmol/L and 1μmol/L of icariin could inhibit the apoptosis of MSC. Icariin could not only improve the expression of CXCR4 in MSC, but also increase the number of transmembrane migrated MSC. After the addition of CXCR4 antagonist AMD3100, there was no significant difference in the number of cell migration among the different groups. Conclusion Icariin with appropriate concentration can promote the proliferation, survival and migration of MSC. SDF-1/CXCR4 signaling pathway is involved in the regulation of MSC migration by icariin.

ABSTRACT

Objective To explore the role of clinical pharmacist in individualized treatment of hypertension.Methods A patient withH hypertension receiving pharmaceutical care from clinical pharmacists was retrospectively analyzed.Results Patient's MTHFR (C677T) gene type was TT homozygous.Clinical pharmacist suggested doctor modify treatment,and then patient's plasma homocysteine dropped from 61.5 to 16.0 μmol·L-1,and blood pressure dropped from 173/ 111 mmHg(1 mmHg =0.133 kPa) to 130/80 mmHg.Conclusion Clinical pharmacist provides individualized treatment for patient with hypertension to ensure the safety and effectiveness of the drug by genotyping.

ABSTRACT

Objective To explore the effects of electroacupuncture on brain derived neurotrophic factor (BDNF) of rats with sciatic nerve injury (SNI); To discuss its biological mechanism for treatment of SNI. Methods Fifty adult male Wistar rats were chosen, and the sciatic nerves of rats were cut off and pulled on both sides of the cut ends into nerve regeneration chamber. The rats were randomly divided into normal group, sham-operation group, model group, and electroacupuncture group. In the electroacupuncture group, the rats were treated by electroacupuncture for 28 days. After the treatment, the nerve regeneration was observed through HE staining. Immunofluorescence was used to analyze the expression changes of BDNF in the nerve tissue and spinal cord. ELISA was used to observe the changes of expression of serum BDNF. Results The amount of axon regeneration in the electroacupuncture group was obviously more than that in the model group, and the outline of the tissue more clear. Electroacupuncture could promote the expression of BDNF in the nerve, spinal cord and serum of SNI of rats compared with model group (P<0.01). Conclusion Electroacupuncture can promote the repairment and regeneration of SNI in rats by upregulating the expression of BDNF.
