Objective:To evaluate the efficacy of drug abuse prevention and treatment and the needs of drug users.Method:A multi-center survey was carried out with a self-designed questionnaire in 10 compulsory detoxification centers among 2400 drug users.Results:The results of the survey indicate that 76.2% of the subjects had never received any drug abuse prevention education before they using drugs. However, 53.6% of the subjects who received drug abuse prevention education thought that the promotion and education are not helpful or hardly helpful. Drug abusers were basically satisfied with most "software" and "hardware" services of the present compulsory drug abuse center. What should be improved is the effectiveness of treatment. Meanwhile, Drug abusers thought that the most urgent needs were: learning skills to prevent relapse; helping to improve living surrounding and helping to find jobs etc.Conclusion:The coverage of the present drug abuse prevention education is not wide enough and need to be improved in its effectiveness and orientation. In order to make drug abuse treatment more effective and meet drug abusers' needs, multi-department and cross-discipline cooperation, exploration and efforts from the whole society are necessary.

Objective To establish a method of culturing mesenchymal stem cells from umbilical cord blood. Methods The mononuclear cell fraction of umbilical cord blood was isolated with the aid of a Ficoll/Hypaque gradient, then MSC were cultivated in serum containing medium or serum-free medium. The serum containing medium (SC) consisted of LG-DMEM supplemented with 10% fetal calf serum and 10-6M hydrocortisone, with a final cell concentration of 1?106 cells/ml. The serum-free medium (SF) was supplemented with 1?10 -6M hydrocortisone and 40ng/ml fibronectin with a final cell concentration of 1?106 cells/ml. After a week, 50% of the media were renewed. Before reaching the monolayer phase cells were trypsinised and re-cultured under similar conditions for the another 3 weeks. Cells were counted at the beginning and the end of the culturing period. Phenotypes were identifiad by PAS, NAE, ALP staining. Identification of surface markers and cell cycle analysis of MSCs were performed with flow cytometry. Results Adherent cells appeared 24h after plating of mononuclear cells. The cells formed adherent heterogeneous cell populations after 4-7 days in culture, and they consisted of round and spindle-like cells. In the primary passage of culture, the cells proliferated slowly and became confluent in 14-20 days. When subcultured, the heterogeneous cell populations became homogeneous assuming flat and fibroblast-like shape. Though colonies in the medium containing serum formed earlier than those in the serum-free medium, passage times and cell morphology were the same. The total cell numbers in SF group were lower than those of SC group. The percentage of cells at G0-G1 cell cycle was higher in SF group than that of SC group with significant difference. By flow cytometry analysis, cells of two groups were negative for CD34, CD13 and CD45, but strongly positive for specific surface markers such as CD166, CD29, CD105 and CD54. Conclusion Serum-free medium was superior to medium containing serum for culturing MSCs.

The study aims to develop an LC-MS/MS method for the simultaneous determination of amygdalin and paeoniflorin in urine samples, and to investigate their urinary excretion characteristics in healthy volunteers after intravenous infusion administration of Huoxue-Tongluo lyophilized powder for injection (HTLPI). The urine samples were extracted by methanol, and then separated on a Hedera ODS-2 column with a mobile phase of acetonitrile and 5 mmol · L(-1) ammonium acetate buffer solution containing 0.05% formic acid (20:80). Electrospray ionization source was applied and operated in the positive ion mode using MRM. The method exhibited good linearity over the concentration range of 0.03 -40 µg · mL(-1). The values on both the occasions (intra- and inter-day) were all within 15% at three concentration levels. No matrix effect and carry-over effect were observed. Amygdalin and paeoniflorin were stable in human urine under different storage conditions. Approximately 79.6% of the administered amount of amygdalin was excreted unchanged in urine within 24 h and which was 48.4% for paeoniflorin. The developed LC-MS/MS method can be applied to evaluate the urinary excretion of amygdalin and paeoniflorin.

Objective To investigate the cytokine spectrum of cultured human amniotic-derived mesenchymal stem cells (A-MSC) for understanding its basis of molecular biology in hematopoietic in vitro.Methods Their hematopoietic cytokines expression was analyzed using RT-PCR in the mRNA level. Results It showed that in vitro subcultured human amniotic-derived mesenchymal stem cells were capable to express many important hematopoietic cytokines such as LIF, SCF, M-CSF, G-CSF, GM-CSF, IL-3, IL-6, IL-11 and so on. Conclusion Production of abundant of hematopoietic cytokines by human amniotic-derived mesenchymal stem cells may be effective for hematopoietic support and HSC transplantation.

Objective To evaluate the clinical application of the auto trigger technique with dual-source CT in cerebral and cervical vessel. Methods 35 patients were randomly divided into three groups, taking triggered threshold as 20HU,50HU and 70HU respectively, CT-values in segments of left middle cerebral artery, superior sagittal sinus, left common carotid artery adjacent to the fourth cervical vertebrate and internal jugular vein by injection at antecubital vein were all measured. Results The discrepancy of peak in artery among groups was not statistically different. It was statistically different in the same segments of vein. Conclusion CTA of cerebral and carotid arteries with the dual-source CT triggered technique can be clearly showed with 20HU as triggered threshold.

OBJECTIVE:To investigate the effects of different doses of sufentanil citrate on hemodynamic indexes and stress response indexes of Crouzon syndrome children with craniofacial reconstruction. METHODS:60 cases of Crouzon syndrome under-going craniofacial reconstruction were selected from our hospital during Jan. 2010-Jan. 2016,and then randomly divided into group A,group B and group C,with 20 cases in each group. 3 groups were given pump injection of Propofol injection 4-8 mg/(kg·h)for anesthesia induction+Sufentanil citrate injection [group A 0.3 μg/(kg·h),pump injection;group B 0.6 μg/(kg·h),pump injection;group C 1.0 μg/kg,iv,0.5 h/time] for anesthesia maintenance, Cisatracurium besilate for injection 0.1 mg/kg,iv,every 40 min, drug withdrawal 5 min before the end of surgery. The hemodynamic indexes(MAP,HR)and stress response indexes(ACTH,cor-tisol)were observed in 3 groups at different time points as well as the occurrence of ADR. RESULTS:MAP levels of group C at 5 min after skin incision,1 h after operation and immediately at the end of surgery were significantly higher than before anesthesia, while those of group B were significantly higher than group C at same time points. HR of group A at 1 h after surgery and that of group B at 5 min after skin incision and 1 h after surgery were significantly higher than before anesthesias;HR of group B at 1 h after surgery was significantly lower than that of group A,and its HR at 5 min after skin incision and 1 h after surgery were signifi-cantly lower than those of group C. ACTH levels of 3 groups at 5 min after skin incision,1 h after surgery and immediately after the end of surgery were significantly higher than before anesthesia. ACTH levels of group B at 5 min after skin incision,1 h after surgery and immediately after the end of surgery were significantly lower than those of group A and C,and the group A was signifi-cantly lower than the group C at same time points. Cortisol levels of group A at 1 h after surgery,and those of group C at 5 min af-ter skin incision,1 h after surgery and immediately after the end of surgery were significantly higher than before anesthesia. Corti-sol levels of group B at 1 h after surgery were significantly lower than those of group A;cortisol levels of group A at 5 min after skin incision and immediately after the end of surgery and those of group B at 5 min after skin incision,1 h after surgery and imme-diately after the end of surgery were all significantly lower than those of group C. There were statistical significance all above(P<0.05). No obvious ADR was found in 3 groups. CONCLU-SIONS:Pump injection of sufentanil citrate 0.6 μg/(kg·h) can maintain analgesic effect of Crouzon syndrome children with craniofacial reconstruction,can keep hemodynamics sta-ble and effectively inhibit stress response during surgery with good safety.
