Objective To explore drug abuse prevention measures by surveying the changes before and after methadone maintenance treatment(MMT). Methods The baseline survey data were obtained from patients who participated in the MTT program for the first time at Wuhan First Health Clinic of Mental Health Center Affiliated to Tongji Medical College between March 2006 and December 2013,and the general conditions of these patients were analyzed. Results There were 1 186 drug abusers, with a male and low education(junior high school and below)dominance. After the initiation of the MMT program,the number of addicted people was highest in 2008,and then gradually decreased after 2009.MMT program achieved obvious social benefits.The proportion of injectable drug use alone was decreased and the rates of oral drug use and snorting were increased over time.Fixed salary and temporary salary were obviously increased in drug abusers after 2009. Daily drug cost was decreased over time. The proportion of community/ media propaganda through which people got to know MMT remained low. Conclusion The community support and educational propaganda should be strengthened at the same time when MMT is carried out.

Objective To explore the feasibility of C14-urea breath test in the diagnosis of child chronic cough.Methods One hundred and twenty children cases of chronic cough were collected as the research subjects and divided into the C14 group(adopting C14-urea breath test for diagnosis) and combined group(C14-urea breath test combined with routine diagnostic method) according to different diagnostic means,60 in each group.Then the positive diagnostic rate and effectiveness were analyzed and compared between the two diagnostic methods.Furthermore the ROC curve was adopted to evaluate its diagnostic value.Results The positive diagnosis rate in the C14 group was 76.67%,which was significantly lower than 95.00% in combined groups,the difference was statistically significant (P<0.001).The sensitivity and positive predictive value in the combined group were obviously higher than those in the C14 group (P<0.01),but there were no statistically significant differences in specificity and negative predictive value between the two methods (P>0.05).The expression levels of serum hs-CRP and IL-6 in the C14 group were significantly higher than those in the combined group,but the expression level of IL-10 was obviously lower than that of the combined group (P<0.05).The AUC in the ROC curve of combined group was significantly higher than that of the C14 group(P<0.05).Conclusion The C14-urea breath test can serve as a supplementary diagnosis means in child chronic cough,and its combining with the routine diagnosis method can significantly increase the diagnosis effectiveness.

Objective To investigate the relationship between autophagy in spinal dorsal horn and development of morphine tolerance in rats.Methods Twenty-four healthy male Sprague-Dawley rats,in which intrathecal (IT) catheters were successfully placed,were randomly divided into 3 groups (n =8 each):control group (group C),morphine tolerance group (group M) and morphine + rapamycin as a reinforcing agent for autophagy group (group MR).Morphine tolerance was induced with IT morphine 20 μg twice a day for 7 consecutive days.While the equal volume of normal saline was given in group C.In addition,rapamycin 2.3μg was injected intrathecally at the second injection of morphine on 3rd day lasting for 3 consecutive days in group MR.Mechanical withdrawal threshold (MWT) to yon Frey filament stimulation was measured before IT injection and 30 min after the second IT injection on 1st,3rd,5th and 7th days.The rats were sacrificed 1 h after the last MWT measurement and the L4-6 segment of the spinal cord was removed for determination of the total mammalian target of rapamycin (mTOR) and phosphorylated mTOR(p-mTOR) and autophagy marker protein LC3 Ⅱ expression in spinal dorsal horn by Western blot.The percentage of p-mTOR expression in total mTOR expression was considered as reflection of the activity.Results MWT was gradually decreased with the prolongation of time of IT injection (P ＜ 0.05).Compared with group C,MWT was significantly increased during IT injection,mTOR activity was decreased and LC3 Ⅱ expression was up-regulated in groups M and MR (P ＜ 0.05).Compared with group M,MWT was significandy increased on 3rd,5th and 7th days after IT injection,mTOR activity was decreased and LC3 Ⅱ expression was up-regulated in group MR (P ＜ 0.05).Conclusion Increased autophagy in spinal dorsal horn is the regulatory mechanism of the body during the development of morphine tolerance in rats and can delay the development of morphine tolerance.

BACKGROUND: 3-nitropropionic acid(3-NP) can inhibit the process of oxidative phosphorylation and injure the energy metabolism of the cell and thereby induce cell injury. However, small dose of 3-NP can excite intrinsic cellular protective factor to protect neurons and increase the tolerance of neurons to ischemic hypoxia through mild inhibiting the process of oxidative phosphorylation. It is unclear whether it also has the similar effect on dopaminergic neurons.OBJECTIVE: To investigate whether 3-NP preconditioning could enhance the tolerance of dopaminergic neurons to MPP+(1-methyl-4-phenylpyridine)toxicity.DESIGN: A randomized controlled exploring research based on neuroblastoma SH-SYSY cell that could secrete dopamine.SETTING: Department of neurology of a university hospital.MATERIALS: The study was conducted in the Laboratory of Pathophysiology of Tongji Medical College between March 2003 and November 2003. SH-SYSY cell was obtained from the Cell Center of Peking Union Medical University.INTERVENTIONS: Cells were randomly divided into 6 groups. MPP+ was added into the cultured dopaminergic neuron SH-SY5Y cells for the establishment of the cell model for Parkinson disease. Before the admission of MPP+ (0.25 mmol/L), 3-NP(0. 2 mmol/L) was added once or repetitive times to form preconditioning. Microculture tetrozolium(MTT) was used to detect cell survival rate, and[3H] DA uptake rate was used to test the anterior synaptic function of dopaminergic neurons.MAIN OUTCOME MEASURES: Major consequence: Cell survival rate;Minor consequence: [3H] DA uptake rate.RESULTS: Cell survival rate of MPP+ group was 54.3%, which was significantly lower than that of blank control group( P ＜ 0.01) . After 3-NP preconditioning, cell survival rate significantly elevated, which was 71.8%(single) or 85.2% (repetitive) . There was significant difference between single preconditioning and repetitive preconditioning( P ＜ 0.05 ). The results of[3H] DA uptake rate were similar to that of cell survival rate. [3H] DA uptake rate was 65.8% (single) or 80. 3% (repetitive), which was significantly higher than 50. 1% of MPP+ group. And moreover, repetitive preconditioning had more favorable effect than single preconditioning. Simple admission of 3-NP had no impact on cells.CONCLUSION: 3-NP preconditioning can significantly enhance the tolerance of dopaminergic neuron to MPP+ toxicity, which has significant protective effects on dopaminergic neuron. Repetitive preconditioning have more significant protective effects.

Objective To explore the role of OAZ gene in the pathogenesis of systemic lupus erythe-matosus (SLE) by using RNA interfering technique. Methods Peripheral blood mononuclear cells (PBMC) from SLE patients were collected. Each sample was equally divided into four groups for cell culture in 96 well plates. Specific siRNA for OAZ and GAPDH were concordantly added to the experimental group and the positive control group, while nonspecific siRNA was added to the negative control group and only culture medium was added to the Mock control group. Cells and supernatants were harvested after culturing for 72 hours, then RNA was extracted and reverse transcripted to cDNA. OAZ, Id1, Id2, Id3, Id4 mRNA expression levels were analyzed by using real-time PCR. Levels of IFN-γ, IL-4, IL-10, IL-12, IL-21, CCL2, ANA in the supernatant were tested by ELISA. Relationships between the expression levels of OAZ mRNA with levels of cytokines and ANA were analyzed. Results OAZ, Id1, Id2, Id3 gene mRNA expression levels (△Ct: 12.5±1.4, 8.9±1.5, 4.3±0.8, 8.04±1.1) in the experimental group were significantly decreased comparing to those in the negative control group (△Ct: 10.2±1.1, 6.5±1.2, 2.4±1.3, 6.2±1.2 respectively, P<0.05). Levels of IFN-γ, IL-10, IL-12, IL-21 and ANA in the experimental group were significantly lower than those in the negative control group (P< 0.05), but level of CCL2 was higher than the negative control group (P<0.05). Difference of OAZ mRNA expression levels (△△Ct) between the experimental group and the negative control group was negatively correlated with changes of ANA, IL-21 levels, but positively correlated with changes of Th1/Th2, CCL2. Conclusion OAZ siRNA can effectively reduce the expression of genes involved in the OAZ signaling pathway in SLE. OAZ may lead to abnormal production of ANA via regulating Id genes and cytokines.

Objective To explore the expression levels of interferon-inducible genes in patients with systemic lupus erythematosus ( SLE) , and to validate these gene expressions as potential biomarkers for the differentiation of disease flare and infection.Methods Peripheral blood was obtained from 48 SLE, 16 rheumatoid arthritis ( RA) patients and 26 normal controls, and total RNA was extracted and reverse transcribed into complementary DNA.Real-time PCR technique was used to determine the gene expressions of MX1, OASL,OAS1, ISG15 and LY6E at transcription level.Univariate logistic regression analysis and multivariate conditional logistic regression model were applied to analyze 5 related factors for infection or activity.Results ( 1 ) The expression levels of MX1, OASL, 0AS1, ISG15, and LY6E mRNA in SLE patients were significantly increased as compared with normal controls ( P all < 0.01 ) , while the expression levels of OASL,OAS1 ,ISG15 and LY6E mRNA in SLE patients were also higher than those in RA patients (P all <0.05 ).(2)There were no significant difference between male and female patients of the 5 gene expression in SLE patients.(3) By logistic regression analysis, ISG15 and LY6E were independent risk factors for active SLE patients (P <0.01) , OASL expression was an independent risk factor for SLE patients with infection ( P = 0.003 ).Conclusion All the 5 interferon inducible genes are highly expressed in SLE patients, in which ISG15 and LY6E are independently associated with disease flare, while OASL may be helpful for the evaluation of infection in SLE patients.
