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. 55. 17 mIU/ L)during first-trimester(T1)and control(0. 2≤TSH≤3. 0 mIU/ L), observation(3. 05. 22 mIU/ L) during second-trimester(T2). The results showed that the rupture of membranes, preterm labor, and total obstetrical adverse events in the observation group were significantly higher than those in control group during T1(all P<0. 05), no statistical significance between control group and treatment group. The rupture of membrances in the observation group was significantly higher compared with control group during T2 ( P < 0. 05), no significant difference in other adverse pregnancy outcomes between these two groups. Compared with control group during T1, the proportion of adverse pregnancy outcomes in observation group during T1 was significantly increased(P<0. 05). The elevated TSH is one of the risk factors for the increased incidence of adverse pregnancy outcomes at the first half of pregnancy, especially during T1. L-T4 treatment reduces the incidence of adverse pregnancy outcomes.

Three female patients admitted with elevated creatine kinase,impaired muscle on electromyogram,and positive repetitive nerve stimulation and neostigmine tests were diagnosed as polymyositis (PM) with myasthenia gravis (MG).Twenty five more cases were retrieved by literature search,and the clinical data of total 28 cases were analyzed.There were 10 males and 18 females with an average age of 56 years.The clinical manifestations include dyspnea(43％),dysphagia(43％),ptosis (43％),dysarthria(29％),diplopia(18％),cough after drinking(14％),myalgia(11％).Thirteen out of 26 cases (50％) had positive results in repetitive nerve stimulation (RNS) and 10/11 showed positive reaction in neostigmine test.Serum positive anti-acetylcholine receptor was detected in 21 out 23 patients (91％).

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.

In order to clarify the chemical constituents of Cistanche deserticola cultured in Tarim desert, a systematically phytochemical investigation was carried out. The chemical constituents were isolated by column chromatography, such as silica gel, Sephadex LH- 20, MCI gel, ODS and semi-preparative HPLC, and their structures were determined on the basis of MS, NMR spectroscopic analysis and/or comparison with literature data. Eleven lignans were isolated from the 85% ethanol extract of the stems of C. deserticola cultured in Tarim desert. Their structures were identified as (+)-syringaresinol-4'-O-β-D-glucopyranoside (1), (+)-isoeucommin A (2), eucommin A (3), (+)-pinoresinol monomethylether β-D-glucoside (4), lariciresinol 4'-O-β-D-glucopyranoside (5), lariciresinol 4-O-β-D-glucopyranoside (6), conicaoside (7), dehydrodiconiferyl alcohol 4-O-β-D-glucopyranoside (8), dehydrodiconiferyl alcohol γ'-O-β-D-glucoside (9), citrusin A (10), and alaschanioside A (11). Compounds 1, 3-7, 10 and 11 were isolated from this genus for the first time, and compounds 2, 8 and 9 were obtained from this species for the first time.

Exploring the influence of extract of Ginkgo biloba (EGB) on the proliferation, apoptosis of ACC-2 cell in lacrimal adenoid cystic carcinoma and analyzing the influence of EGB on the gene expression of Survivin and TIP30 based on the levels of the gene and protein. ACC-2 cell in human with ACC of lacrimal gland disposed by EGB of different concentration was in vitro cultured. MTT method was used for cell proliferation detection. Annexin V/PI double-staining flow cytometer was used to detect cell apoptosis and cell cycle. Survivin and TIP30 gene expression together with protein expression were analyzed by RT-PCR and Western blotting. And it is indicated that EGB has inhibitory effect on the proliferation of ACC-2 cell in vitro. Furthermore, the dose-effect relationship was significant. Compared with the control group, it had statistical difference (P <0.01). The inhibitory concentration 50% (ICso) is 88 mg . L-1. By flow cytometer examination, it was indicated that EGB can gradually increase ACC-2 cell in G0-G1 stage and decrease it in G2-M and S stage. With the increase of dose, the apoptosis rate of ACC-2 cell obviously increased (P <0.05 or P <0.01). Both of the expression results of RT-PCR and Western hybrid proteins have showed that the concentration of EGB increased, it could be seen a significant decrease in Survivin gene expression (P <0.01). Meanwhile, the TIP30 gene expression got a significant increase. Therefore, EGB can effectively inhibit ACC-2 cell Survivin gene expression in human with adenoid cysistic carcinoma of larcrimal gland as well as promoting TIP30 gene expression, inducing the ACC-2 cell apoptosis and inhibiting tumor cell proliferation, which provided a certain theoretical and experimental basis for the application of Chinese herbal medicinal ingredient in the treatment of tumors.
