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.

Objective: To investigate the bonding strength of different resin composites .Methods:Methacrylate-based resin APX and silorane-based resin composite P90 were chosen in this study , with their corresponding adhesives Clearfil SE Bond ( SE) and Filtek P90 System Adhesive ( SA) .The speci-mens were divided into three groups:(1) bulk group, filling each block with the same composite , then curing;(2) direct filling group, curing and polishing one composite , then filling a new composite direct-ly;( 3 ) bonding group , after curing and polishing one composite , conditioning the surface with adhe-sives, then filling a new composite.Cut each resin blocks into 1 mm ×1 mm ×14 mm each piece, detec-ting the microtensile strength , and analyzing by One-Way ANOVA and LSD .Results: ( 1 ) The micro-tensile strength of the bulk group was the highest .(2) In direct filling group, the microtensile strength of 4 subgroups showed no statistical significance with each other but lower than that of the bulk group .(3) In bonding group, the microtensile strength of repairing with APX was higher than that with P 90.When repairing with same composite , the microtensile strength was higher if the resin type of substrates was same with restorations than that was different .The microtensile strength of adhesives SE was higher than that of SA.(4) The sorting of the microtensile strength: bulk>SE bonding APX >SA bonding APX>SE bonding P90=direct filling>SA bonding P90.Conclusion:Retention force is higher when substrates are repaired with methacrylate-based resins and corresponding adhesives .Retention force is lower when repaired with silorane-based composites and corresponding adhesives .Types of the substrate composites show no influence on the bonding strength .

AIM: To discuss the clinical applications of methods to localize nasal cut ends and the effects of Z-plasty in the surgeries for lower eyelid longitudinal laceration combined with lower lacrimal canaliculi disruption.
METHODS: From September, 2010 to October, 2013, a total of 37 patients ( 37 eyes ) with lower eyelid longitudinal laceration combined with lower lacrimal canaliculi disruption were operated for anastomosis of lacrimal canaliculi disruption and suture of lower eyelid longitudinal. Different methods to search for the nasal cut ends of lacerated lacrimal canaliculi, such as “under a microscope directly”, “guided by probing needle” and“pigtail curved probe”. Then, to repair lower eyelid longitudinal laceration with Z-plasty transposition flaps. Follow up was 3mo~2a after operation.
RESULTS: All nasal cut ends could be found successfully on 37 patients;Lacrimal duct unobstructed in 31 patients (83. 8%), improved in 5 patients (13. 5%), invalid in 1 patient (2. 7%),the overall successful rate was 97. 3%; the eyelids repair was satisfactory, small scars, the appearance and function was normal.
CONCLUSION: The nasal cut ends can be found successfully by “directly under a microscope”, “guided by probing needle” and“pigtail curved probe”;the effect of silicone drainage tube used as lacrimal canaliculi bracket is satisfactory; most patients gained excellent recovery for both appearance and function after Z-plasty.

International clinical trials register is one of the global measures to realize transparency in clinical trials and also one of a powerful measure to improve the quality of clinical trials. Many scholars studying the quality of TCM clinical trials find that they are poor in quality and lack transparency. Furthermore, they find that TCM clinical trial registry has many problems. We must base on the successful experiences of WHO and international clinical trial registry to establish technical specifications for registry of traditional Chinese medicine clinical study of their own. Then, it can effectively improve the overall level of TCM clinical studies. We have suggested some concrete and feasible measures to establish technical specifications for registry of traditional Chinese medicine clinical study of their own based on the problems of TCM clinical trial registry.

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.

In recent 10 years, clinical trials of Chinese medicine and pharmacy (cMP) at clinicalTrials.gov.(USA) are gradually increasing. In order to analyze features of CMP clinical register, ClinicalTrials.gov register database were comprehensively retrieved in this study. Included clinical trials were input one item after another using EXCEL. A final of 348 CMP clinical trials were included. Results showed that China occupied the first place in CMP clinical register, followed by USA. CMP clinical trials, sponsored mainly by colleges/universities and hospitals, mostly covered interventional studies on evaluating safety/effectiveness of CMP. The proportions of studies, sponsored by mainland China and companies, recruitment trials and multi-center clinical trials in interventional trials were increasing. The proportions of studies sponsored by Hong Kong and Taiwan, research completed trials, unclear research status, phase III clinical trials, and published research trials in interventional trials were decreasing. Published ratios of CMP clinical trials were quite low. There were more missing types and higher proportions in trial register information.
