Objective To investigate the expression levels of microRNA(miR)-125b, miR-29a and miR-155-5p in ce?rebrospinal fluid (CSF) and plasma from the patients with tuberculous meningitis and their clinic significance. Methods Cerebrospinal fluid and plasma samples were collected from 20 patients with tuberculous meningitis (tuberculous meningitis group) and 20 patients suffered from primary headache (control group). The total RNAs were extracted.The levels of miR-125b, miR-29a and miR-155-5p were determined by real-time quantitative PCR (q-PCR). Results Levels of miR-29a and miR-125b in both CSF and plasma of patients in tuberculous meningitis group were significantly higher than those in pa?tients from control group with statistical significance (P<0.01). Mean time, the level of miR-155-5p in plasma but not in CSF of patients in tuberculous meningitis group was higher than those in control group with statistical significance ( P<0.01). Conclusion Expression of miR-125b, miR-29a and miR-155-5p may participate in regulating the occurrence and development of tuberculous meningitis. And miR-125b and miR-29a may be used as potential biomarkers for diagnosing tu?berculous meningitis.

Objective To study the effect of electroacupuncture (EA) combined with repetitive transcranial magnetic stimulation (rTMS) on endogenous neural atem cells, as well as learning and memory in rats with cerebral ischemia. Methods One hundred and twenty male Wistar rats were randomly divided into 5 groups: a normal group, a model group, an EA group, a rTMS group and an EA plus rTMS group. After establishing acute middle cer-ebral artery occlusion, the rats in the various experimental groups were treated with EA, rTMS or EA plus rTMS. The rats' ability to avoid an electric shock was observed using a jumping stand, Immunohistochemical techniques were used to measure the infarct area and the number of Brdu-positive cells. Results A small quantity of Brdu labelled cells was observed in the subgranular zone (SGZ) and the subventricular zone (SVZ) in rats in the normal group. In the EA, rTMS and EA plus rTMS groups, the numbers of Brdu labelled cells in the SVZ and SGZ was significantly higher than in the model group after both 7 and 14 days. The expression of Brdu around the SVZ and SGZ of the 3 treatment groups increased, especially in the EA plus rTMS group. At 7, 14 and 28 d there was significant improve-ment in the neural function and electric shock avoidance test scores in the EA, rTMS and EA plus rTMS groups com-pared with the model group,with the EA plus rTMS animals scoring best. Conclusion EA plus rTMS can promote the proliferation of nerve stem cells, facilitate neurological recovery and improve learning and memory in rats after cerebral ischemia.
