Chinese Traditional and Herbal Drugs 2016;47(5):799-802
Objective: To observe the therapeutic effect and safety of Yaotongning Capsule in the treatment of lumbar hyperplasia. Methods: A random, double-blind, placebo controlled, multicenter clinical research method was used. The lumbar hyperplasia patients (144 cases) were selected, divided into Yaotongning Capsule group (treatment group) with 72 cases, 72 cases completed; and placebo group (control group) with 72 cases, 70 cases completed. The treatment lasted for 2 weeks. After treatment, the symptom of traditional Chinese medicine and pain relief situation were observed in the two groups. Results: The curative effects of Yaotongning Capsule in the treatment of lumbar hyperplasia disease (cold-dampness stagnation syndrome) were as follows: The control rate in treatment group was 41.5%, and that in the control group was 0.0%, superiority test (P<0.001) was established. Pain relief: the relieve rate in treatment group was 86.1%, and that in the control group was reduced to 45.7%, there was significant difference between the groups (P<0.001). Conclusion: Yaotongning Capsule in the treatment of lumbar hyperplasia (cold-dampness stagnation syndrome) has obviously curative effect, and can effectively reduce the pain caused by lumbar hyperplasia.

Objectiye To study the mechanism by which transcranial magnetic stimulation (rTMS) affects cognitive dysfunction in vascular dementia (VD). Methods Thirty-six male Wistar rats were randomly divided into a control group, a VD group, a low frequency rTMS group and a high frequency rTMS group. Two-vessel occlusion was employed to induce VD models. Low frequency rTMS group rats were given 0.5 Hz rTMS for six weeks. High frequency rTMS group rats were given 5 Hz rTMS for six weeks. Morris' water maze test was used to measure their spatial learning ability and memory. The ultrastructures of the synapses in the four groups were detected with transmission electron microscopy. The expression of synaptophysin (SYN), brain derived neurotrophic factor (BDNF) and Nmethyl-D-aspartate receptor 1 ( NMDAR1 ) mRNA and protein in the hippocampus were determined by real-time PCR and Western blotting. Results The behavior and morphology of the rats treated with rTMS improved. The average expression of SYN, BDNF and NMDAR1 mRNA and protein in the low frequency rTMS group and the high frequency rTMS group were significantly higher than in the VD group. Conclusion rTMS can provide a rehabilitative effect for VD. The mechanism might be associated with enhancing the expression of SYN, BDNF and NMDAR1 in the hippocampus.

[Summary] A total of 352 pregnant women were selected in Affiliated Hospital of Qingdao University. Serum levels of TSH and FT4 were determined and pregnancy outcome were observed in all subjects. According to the standard of American Thyroid Association(ATA) published in 2011 and the Chinese Guideline of Gestation Thyroid Disease published in 2012, the subjects were grouped into control(0. 1≤TSH≤2. 5 mIU/ L), observation(2. 5

According to the sequence of P450 cDNA of Eleutherococcus senticosus, specific primers were designed. Frokaryotic ex pression vector pET30a-P450 was constructed and the prokaryotic expression conditions were optimized. Results showed that the BL21 after being transformed with the recombinant expression vector accumulated the high amount of recombinant protein. SDS-PAGE analysis showed that the recombinant protein was about 53 kDa. The recombinant accumulated the highest amount of recombinant protein af ter IPTG (1 mmol x L(-1)) at 27-37 degrees C for 24 h. Consequently P450 gene of E. senticosus could be expressed successfully by prokaryotic expression vector pET30a-P450. Induction temperature, IPTG concentration, medium type and amount of induction time could all influence the expression of target protein, but the impact strength was different.

For the establishment of chemical library of protoberberines provided for the bio-activity screening, the target compounds were synthesized by thermal degradation and nucleophilic substitution reactions with the bio-active alkaloid, palmatine (1), as the raw material, and their structures were identified and conformed by 1H-NMR and MS spectra. Among them, 13 compounds were new.

Objective To investigate the role of nitric oxide (NO) in the protective effects of morphine postconditioning against ischemia-reperfusion (I/R)-induced myocardial apoptoais. Methods Sixty pathogen-free SD rats were randomly divided into 4 groups ( n = 15 each) : group Ⅰ sham operation (S) ; group Ⅱ I/R; group Ⅲ morphine postconditioning ( M ) and group Ⅳ M + L-NAME ( non-selective NOS inhibitor). The animals were anesthetized with intraperitoneal pentobarbital 60 mg/kg, tracheostomized and mechanically ventilated. ECG was monitored. Right carotid artery was cannulated for BP monitoring and left jugular vein was cannulated for drug and fluid administration. Myocardial ischemia was induced by 45 min occlusion of left anterior descending coronary artery (LAD) followed by 120 min reperfusion. In group S LAD was exposed but not occluded; in group M morphine 1.25 mg/kg was injected iv over 5 min from 3 min before reperfuaion to 2 min of repeffuaion and in group M + L-NAME L-NAME 10 mg/kg was injected iv at 20 min before myocardial ischemia. Hemodynamic changes were monitored. The animals were killed at the end of 120 min reperfusion and their hearts removed. Myocardial apoptosis was determined by TUNEL technique. The expression of Akt phosphorylation was assessed by Western blotting. The NO content in myocardium was measured by a chemiluminescence detector.Results A large number of TUNEL positive cells (18.4 ± 1.1 ) % were observed in group I/R. Morphine postconditioning exerted a significant anti-apoptotic effect. The number of TUNEL positive cells was reduced to (10.8 ± 1.2)%. The myocardial eNOS phosphorylation expression and NO content were significantly increased in group M as compared with group I/R. The anti-apoptofie effect and increased NO production were significantly reversed by L-NAME. However, pretreatment with L-NAME did not inhibit the phosphorylation of eNOS in group L + M. Conclusion In vivo, morphine postconditioning can significantly reduce I/R-induced myocardial apoptosis through phosphorylation of eNOS and increase in NO production.
