BACKGROUND: In addition to physical disability, stroke may also result in psychological impairments usually manifested by depression and anxiety.Regardless of the primary or secondary onset of anxiety, anti-depressants should be given for treatment of the anxiety and depression besides routine treatment of the primary condition underlying the symptoms.OBJECTIVE: To compare the effect of different treatment protocols with or without anti-depressants and different anti-depressants on poststroke anxiety and depression as well as the neurological functions.DESIGN: Randomized controlled double-blind clinical trial.SETTING: Departments of Psychiatry and Neurology of the Second Hospital Affiliated to Lanzhou University.PARTICIPANTS: Ninety patients aged 41-72 years with post-stroke anxiety and depression, who were admitted in the Departments of Psychiatry and Neurology of the Second Hospital Affiliated to Lanzhou University between July 1999 and December 2002, were enrolled in this study and randomized equally into Paxil group, imipramine group and control group.METHODS: After emergency management for 1-2 weeks in the acute stage, the stroke patients showed clear consciousness and stable life signs without any understanding problems. Patients in the control group received conventional treatment combined with rehabilitative training, while patients in the other two groups were given additional Paxil (20 mg/day) or imipramine (50-150 mg/day) for totally 12 weeks. The neurological deficits and capacity for independent living of the patients were assessed with Hamilton Depression Scale (24 items) and Hamilton Anxiety Scale (14items) at 2, 4, 8, and 12 weeks during the treatment. A reduction of the score for Hamilton anxiety and depression scale by over 75% suggested a cure of depression and anxiety, 50% but < 75% obvious improvement,25% but < 50% improvement, and < 25% non-response. Basically recovered neurological function was indicated by a reduction of neurological deficit score by 90%-100%, remarkable improvement by 46%-89%, improvement by 18%-45%, and non-response or exacerbation by a reduction less than 17%.MAIN OUTCOME MEASURS: ① Neurological function recovery of recovery of the patients after treatment; ② Poststroke anxiety and depression status before and after treatment; ③ Therapeutic effects on depression,neurological functions, severity of neurological deficit, and capacity of independent living. ④ Adverse events and side effects.RESULTS: One patient in Paxil group and 3 in the control group failed to be available for follow-up study, and 3 patients in imipramine group withdrew from the study due to adverse events, so that 83 cases were analyzed.At 2 and 4 weeks in the treatment, the scores for neurological deficits and capacity for independent living exhibited obvious changes (P < 0.01),which gradually stabilized at 8 and 12 weeks (P < 0.05), and significantly greater improvement in the neurological function and capacity for independent living was observed in Paxil group than in the control group (P< 0.01), but the differences between imipramine group and the control group and between Paxil group and imipramine group were not statistically significant (P > 0.05). The scores for Hamilton Depression Scale and Hamilton Anxiety Scale were obviously lower in Paxil group and imipramine group at 2, 4, 8 and 12 week than those in the control group (P< 0.01-0.001), but similar between the former two groups at 12 weeks (P> 0.05). Paxil and imipramine on resulted in curative rates of anxiety and depression of 86.6% and 85.1%, respectively, which were obviously higher than that of the control group (46.6%); the improvement rate ofneurological function in Paxil group, imipramine group and control groupwas 89.6%, 70.3% and 56.6%, respectively, with that of Paxil groupsignificantly higher than that of the control group (P < 0.01), but the difference between imipramine group and control group was not signifi cant (P > 0.05).CONCLUSION: Patients with poststroke anxiety and depression shouldreceive appropriate interventions with anti-depressants in addition to treat ment of neural function impairment. Paxil and imipramine haye similar effect in treating anxiety and depression, but the former can be for its less side effects, better compliance on the part of patients and good effect inpromoting neurological function recovery.

BACKGROUND: There is often a physical and psychosocial effect in burn injury, and the degree of mental stress reaction is related to social support, individual experience and personality characteristics.OBJECTIVE: To investigate the mental stress reaction, the degree of social support and the Minnesota Multiphasic Personality Inventory (MMPI)personality characteristics in acute burn patients, and to analysis the influence factor of mental stress reaction.DESIGN: Cross-sectional study.SETTING: West China Mental Health Center of Sichuan University, Burn Department of Mianyang Municipal Central Hospital, and Burn Department of General Hospital of Panzhihua Iron and Steel Company.PARTICIPANTS: From April 2003 to April 2005, totally 104 mild, moderate or severe burn patients, including 92 males and 12 females, aged 12-60 years, selected from Mianyang Central Hospital and Department of burn of General Hospital of Panzhihua Iron & Steel Co., Ltd took part in the study.METHODS: The emotional problems and personality characteristics were measured with the Hamilton Rating Scale for Depression (HAMD), the Hamilton Rating Scale for Anxiety (HAMA), the Minnesote Multiphasic Personality Inventory (MMPI), the Social Support Rating Scale (SS) as well as general clinical data,by the rating scales 3 day after burn. The patients were divided into anxiety-depression group (n=51) and normal emotion group (n=53) according to their anxiety-depression scores (anxious score> 7,depressive score> 8), those influencing factor included burning total area,age, sex and society support, Stepwise Regression was introduced to get the main factors that influenced mental stress reaction.MAIN OUTCOME MEASURES: ① Scores of each scale and comparison of general clinical data in each group; ② stepwise regression analysis of depression and anxiety of burn patients.RESULTS: Data of Totally 104 patients was entered the final analysis. ①The scores were 10.4±2.46 and 16.8±5.94 of anxious and depressive patients during acute burn period, which were higher than those in normal group (4.29±2.26, 5.48±2.06, P=0.01). ② The main influential factor for depression were burning area and social supporting availability, and those for anxiety were age, burning area, social supporting availability and subjective social supporting degree. ③ MMPI test results show that T scores in anxiety-depression group were below 60 points, however T-scores were above 60 points in normal group including cheating points, hypomania,schizophrenia, psychasthenia and paranoid ideation CONCLUSION: Burn is a mental crisis to burn patients, which can lead to abnormal emotional reaction and personality change. The depressive and anxious score are positively related with burning area, and are negatively correlated with society supporting availability. The good social support system is benefit to over mental crisis period.

Antisense oligonucleotides (ASODN) for therapy is a genetic technology which is based on the base-complementary principle. DNA or RNA sequence synthesized by biotechnology is transferred into the target cells to form mRNA-DNA or mRNA-RNA double strand for inhibiting the expression of target genes. In this way we can control and treat some diseases. The development of antisense oligonucleotides drugs has opened a new area of genetic pharmacology. This paper reviews its classifications, mechanics and its wide application in the treatment of viral infection, tumor and cardiovascular diseases. At the same time we pose the problems that need solving.

10. Off-treatment responses and predictors and after long-term anti-HBV therapy with nucleos(t)ide analogues
Chinese Journal of Hepatology 2017;25(7):490-494
Recurrence rate after cessation of nucleos(t)ide analogues remains high in clinical practice. According to current evidences, age, HBsAg level, HB VRNA level, time of consolidation therapy and HBV DNA load were considered to be associated with off-treatment responses after cessation of nucleos(t)ide analogues. Combinative factors of several predictors might perform better in future accompanying with further studies of HBV related markers.
