To develop a medication reminder based on Android platform, which can be used to set up personalized reminders quickly and record the patient' s medication time-stamp and related information. In addition, the effect of using the reminder on medication compliance was studied. 14 subjects participated in the evaluation of medica-tion compliance. The differences of dosage and medication rate between the group using and without using reminder were investigated. The dosage and medication rate were got by the pill counting. The Wilcoxon matched -pairs signed rank test showed that the dosage and the medication rate of the group using reminder were higher than that without using reminder significantly(Z= -2. 93, P =0. 003 ). The results demonstrated that the use of the re-minder can improve the medication dose and rate significantly,indicate that the reminder might be a new technical support for clinical research on medication compliance, and also might reduce the workload for medical staff and patients.
2. Synthesis and preliminary pharmacological evaluation of 5-(3-18F fluoropropyloxy)-L-tryptophan
Chinese Pharmaceutical Journal 2013;48(14):1197-1200
OBJECTIVE: To develop 5-(3-fluoropropyloxy)-L-tryptophan(5-18FPTP)as a new amino acid positron emission tomography (PET) tracer for the differentiation of tumor and inflammation. METHODS: 5-18FPTP was prepared by nucleophilic fluorination and alkylation reaction via a two-step procedure. Twenty mice were divided into five groups randomly and the biodistribution of 5-18FPTP in normal mice was determined at different time after injecting the tracer by tail vein. Also, two mice bearing tumor and inflammation received PET imaging at 60 min after injecting the tracer to detect the uptake of the tracer in tumor and inflammatory tissue. RESULTS: The overall synthesis time of 5-18FPTP was about 60 min, the overall radiochemical yield with no decay correction was (21±4.6)%, and the radiochemical purity was more than 95%. High uptake and long retention time of 5-18FPTP in liver, kidney and blood were observed. But low uptake in brain and muscle were found. Furthermore, high uptake of 5-18FPTP in tumor but almost no uptake of 5-18FPTP in inflammatory tissue were observed. CONCLUSION: 5-18FPTP is easy to prepare and can be used to differentiate tumors and inflammatory tissues. It seems to be a potential amino acid tracer for tumor imaging with PET.

AIM: To investigate the details of CD4 + T cell polarized to Th1/Th2 in vitro . METHODS: After isolated the PBMCs and blood-plasma from adult human peripheral blood by Ficoll-Hypaque centrifugation, the PBMC culture procedure with or without the self-blood -plasma was applied to polarize T cells in vitro , these cells were polarized by PHA(20 mg/L),non-PHA respectively. The polarized rates of Th cell after 24 h,48 h,72 h were estimated respectively by flow cytometry following two-color immunofluorescent staining. RESULTS: CD4 +T cell would polarize to Th1/Th2 two subsets after self-cytokines and PHA activation in vitro . The polarized rates of T cell after cultured for 24 h,48 h and 72 h were (13.28%?1.59%)/(12.70%?1.65%),(17.19%?1.03%)/(17.50%?1.30%),(19.49%?2.87%)/(18.58%?1.49%) respectively, but the polarized rates of T cell were very low if without self-blood-plasma. The difference between them was significant. The ratios of Th1/Th2 cells were about 1. CONCLUSION: CD4 +T cell from adult human peripheral blood would polarize to Th1/Th2 two subsets in the presence of self-blood-plasma and PHA(20 mg/L) in vitro , and the cell number of Th1 and Th2 would be in balance.

Objective To investigate the effects of hyperbaric oxygen (HBO) and right median nerve electrical stimulation (RMNS) on the coma arousal therapy in patients with severe traumatic brain injury. Methods Eighty-three patients with severe traumatic brain injury on the recovery phase were randomly divided into control group (n=41) and treatment group (n=42). The patients in the control group were given such routine therapies as reducing the intracranial pressure and giving nutrition to the nerves and conventional rehabilitation nursing. The patients in the treatment group also treated with HBO and RMNS. Glasgow coma scale (GCS), Glasgow outcome scale (GOS), activities of daily living (ADL)scale, European stroke scale (ESS) and Kamofsky performance scale (KPS) were performed on these patients before, 1 and 3 after the treatment. The cerebral blood flow (CBF) and the electrical activity were detected by TCD and brain electrical activity mapping (BEAM). Results As compared with thecontrol group, the treatment group got significant improvement on each scale in the 1st and 3rd month oftreatment (P<0.05). CBF in the treatment group was obviously increased, while that in only 17 patients in the control group was increased. BEAM showed that the diffused inactive echoes were significantly decreased in the treatment group as compared with those in the control group. Conclusion HBO andRMNS can promote brain tissue rehabilitation and accelerate recovery of brain function in patients with severe traumatic brain injury, thereby contributing to the improvement of the level of awareness.

A sensitive antibody-based lateral flow dipstick was developed for ginsenoside Re (GRe) detection. The stick consisted of a sample pad, a conjugate pad, membrane and an absorbent pad. The membrane was coated with two capture reagents, GRe-BSA conjugate and goat anti-mouse antibodies, forming a test line and a control line, respectively. The conjugate pad was saturated with colloidal gold particles coated with affinity purified monoclonal anti-GRe antibody. The visual detection limit was 200 microg x L(-1) of GRe and the reaction time was 10 min. The Panax ginseng roots were identified after these samples (10 mg) were extracted with 5 mL tap water for 30 min at room temperature, and the extracts were tested by the dipsticks and ELISA kit. The true and false P. ginseng could be distinguished with dipsticks. The dipstick could be used to detect the quality of the P. ginseng samples when the extract was diluted 100-folds. The results were compared with those obtained using an indirect competitive enzyme-linked immunosorbent assay (icELISA). The dipstick assay proved to be a sensitive and rapid tool for quality control of P. ginseng.

OBJECTIVETo investigate the effects of sinusoidal magnetic field on isolated sarcoplasmic reticulum (SR) calcium release channel (RyR1) function.
METHODSWith the Ca2+ dynamic spectrum and isotope labeled methods, the Ca2+ release and [(3)H]-Ryanodine binding, the initial rates of NADH oxidation and the production of superoxide of SR exposed to 50 Hz sinusoidal magnetic field (MF) were investigated respectively.
RESULTS0.4 mT, 50 Hz sinusoidal MF exposure for 30 min increased SR Ca2+ release initial rate about 35% from (10.82 +/- 0.89) pmol.mg(-1) pro.s(-1) to (14.69 +/- 1.21) pmol.mg(-1) pro.s(-1); and the [(3)H]-Ryanodine binding by about 15% from (2.13 +/- 0.05) pmol/mg pro to (2.45 +/- 0.07) pmol/mg pro, which regulated by 1 mmol/L NADH with 1 mmol/L NAD+. Meanwhile MF upregulated the rate of NADH oxidation by about 22% from (0.88 +/- 0.11) x 10(-4) FI/s to (1.07 +/- 0.13) x 10(-4) FI/s and upregulated the production of superoxide by about 32% from (0.99 +/- 0.09) x 10(-5) FI/s to (1.31 +/- 0.06) x 10(-5) FI/s.
CONCLUSION0.4 mT sinusoidal MF increases the activity of RyR1 within the low redox potential environment, and promotes NADH oxidase activity and superoxide production.
