Objective: To study the action of acupuncture on the morbid psychology of the heroine addicts at late stage of detoxification. Methods: Four methods including acupuncture, combination of opium and acupuncture, combination of opium and buprenorphine, and combination of opium and Han's drug withdrawal instrument were adopted to study the effect of acupuncture on each factor in 90 listing symptoms of heroin addicts at late stage of detoxification by the self-evaluation scales. Result: Acupuncture had more advantages in improving obsessive symptoms, anxiety, psychogenic symptoms and No 10 factor (P＜ 0.01). Conclusion: Acupuncture can correct the morbid psychology of the addicts and help them enter the recovery stage smoothly.

OBJECTIVE: To compare the effects of de-addiction with the therapy of acupuncture, acupuncture plus opium, opium plus buprenorphine and opium plus Han's instrument for de-addiction and to study the effects of the four therapeutic methods on the protracted withdrawal syndrome and craving. METHODS: The effects of de-addiction were assessed with the opiate withdrawal scale and the craving degree with visual analogue scale (VAS). RESULTS: The dominance of acupuncture treatment for withdrawal syndrome appeared to be after the 6th day, and the dominance for controlling craving showed after the 8th day, moreover, there were little side effects. CONCLUSION: Acupuncture treatment had the potentiality of preventing relapse and could be used for treating the protracted withdrawal syndrome and psychic dependence during the period between the stages of abstinence and rehabilitation.

Objective To investigate the inhibition effect in vitro of mucin gene MUC2 antisense oligodeoxynucleotide (ASODN) on its gene expression and proteolytic enzyme on gastric cancer cell line. Methods Phosphorothioated MUC2 ASODN were synthesized and transfected to SGC7901 cells mediated by lipofectin. MUC2 mRNA and MUC2 protein expressed on SGC7901 cells was detected by RT-PCR and immunohistochemical method. The inhibitory effects of ASODN on proteolytic enzyme, such as cathepsin D, MMP-2 and MMP-9 protein were detected by immunohistochemical staining. The cell cycle and apoptosis were determined by flow cytometry (FCM). Results The inhibition effects peaked at 48th hour after transfection, and the inhibition rate reached 55% when the concentration of ASODN was 0.5 ?mol/L. The number of the cells treated with MUC2 ASODN was decreased as compared to the control cells. MUC2 ASODN transfection could inhibit the transition period of S phase to G2/M phase, and G2/M did not change much. The apoptosis rate was about 4.38%. As compared with blank control group, MUC2 ASODN could significantly inhibit MUC2 mRNA expression of SGC7901 cells. ASODN could downregulate the expression levels of MUC2 protein, MMP-2 and cathepsin D protein. Conclusion MUC2 ASODN transfection could specifically inhibit SGC7901 cells by downregulating the expression levels of proteolytic enzyme.
