Forms and contents of community education and service were multiplicate.ConclusionThe community education and service of mental health should be developed widely for improving people's diathesis.

Membrane proteins are the main undertakers of biofilm function, and also the most important target group for innovative drug discovery and research. About 60% of drugs targets are membrane proteins. Due to the obvious aggregation and denaturation tendency of membrane proteins in aqueous solution, it is difficult to simulate the membrane like environment to maintain the correct conformation of membrane proteins in vitro, which results in the slower-growing research on the structure and function of membrane proteins and related ligand drugs than that of water-soluble proteins. Membrane protein stabilization technology is the premise of establishing high specificity, high sensitivity and high throughput drug screening methods for membrane protein ligands, which is of great significance. In this paper, some techniques for stable separation and purification of membrane proteins are reviewed, including detergents, artificial membranes, polymers, lentiviral particles and so on, as well as their specific applications in drug screening.

OBJECTIVETo explore the effects of integrative medicine (IM) rehabilitation protocolon motor function, activity of daily living, and quality of life (QOL) in hemiplegia patients after stroke.

METHODSTotally 120 patients with post-stroke hemiplegia were allocated to four groups using sealed envalope drawing, i.e., the rehabilitation group, the Chinese medical treatment group, the acupuncture group, and the comprehensive rehabilitation group, 30 cases in each group. Based on routine rehabilitative training, patients in the Chinese medical treatment group, the acupuncture group, and the compre-hensive rehabilitation group received standardized treatment based on syndrome typing, Shi's Consciousness-Restoring Resuscitation acupuncture, Chinese herbs + acupuncture comprehensive rehabilitatino protocol, respectively. The treatmet cycle consisted of 4 weeks with 24-week follow-ups. Fugl-Meyer motor assessment (FMA), Modified Barthel Index (MBI), and Stroke-Specific Quality of Life Scale(SS-QQL), and safety assessment were taken as main effect indices before treatment, at week 4 of treatment, at week 12 and 24 of follow-ups, respectively.

RESULTSThere was no statistical difference in FMA score, MBI score, SS-QOL score among the four groups before treatment (P > 0.05). These scores were significantly improved in the four groups at week 4 of treatment, week 12 and 24 of follow-ups, respectively (P < 0.05). Besides, FMA score and SS-QOL score were significantly improved in the comprehensive rehabilitation group at each corresponding time point, as compared with other treatment groups (P < 0.05).

CONCLUSIONSThe comprehensive protocol could significantly improve motor function, activity of daily living in hemiplegia patients after stroke, and further improve their QOL. Its effect was better than other single treatment.

Objective To evaluate the stability and biodistribution of a novel SPECT-MRI bi-functional agem 99Tcm-Gd-DTPA-DG in tumor-bearing nude mice. Methods DTPA-DG was synthesized and then conjugated with Gd2O3 to generate Gd-DTPA-DG. The tumor-bearing nude mice were scanned by MRI to evaluate the tumor targeting ability of Gd-DTPA-DG. The orthogonal experiment was applied to optimize pH value of reaction medium and reaction temperature. The radiolabeling efficiency was measured by thin layer chromatography. The distribution of 99Tcm-Gd-DTPA-DG in nude mice was evaluated by scintigrapy in vivo. The % ID/g was measured at different time after intravenous injection of 99Tcm-Gd-DTPA-DG. Results The tumor was significantly enhanced by Gd-DTPA-DG with MRI. The radiochemical purity of 99Tcm-Gd-DTPADG was about 98.5% and remained 96.2% at room temperature for 6 h. The tumor was well visualized by 99TcmGd-DTPA-DG SPECT at 2 h after injection. The tumor uptake was (1.48 ±0.12) %ID/g, and the rumor to muscle radioactivity ratio was 2.91. Conclusions MRI contrast of Gd-DTPA-DG may enhance tumor detection. 99Tcm-labeled Gd-DTPA-DG may be useful for tumor imaging and might have a potential role as a SPECT-MRI bi-functional agent.
