Objective To discuss the effect of amisulpride on the prolactin level in serum of first-episode schizophrenic patients and its relationship with symptoms.Methods 45 patients who met the DSM-IV schizophrenia diagnostic criteria and 45 age-and gender-matched healthy controls were assessed the clinical symptoms using positive and negative syndrome scale(PANSS) and pmlactin level in serum was detected using enzymelinked immunosorbent assay.Student's t test was used to compare the prolactin level before and after amisulpride treatment and correlation analysis was used to investigate the relationship between prolactin level in serum and symptoms with P＜0.05 were considered significantly different.Results There was significant increase in prolactin level in serum after amisulpride treatment in first-episode schizophrenic patients((12.52±8.85) ng/ml,(52.60±22.93 ng/ml,t=12.165,P＜0.001).There was a positive correlation between prolactin level in serum and reduction rate of negative symptoms (r=0.24,P＜0.05).Conclusion Amisulpride can increase prolactin level in serum;and the rise of serum prolactin is closely related to the improvement of negative symptoms.

BACKGROUND:Delayed therapy widely occurs in patients with dementia praecox;therefore,it brings a series of difficulties for clinical treatment and rehabilitation.OBJECTIVE:To analyze the influential factors of delayed therapy in patients with dementia praecox.DESIGN:Cross-sectional study based on patients with dementia praecox.SETTING:The Second Affiliated Hospital of Xinxiang Medical College.PARTICIPANTS:A total of 96 patients with dementia praecox,including 52 males and 44 females,were selected from the Second Affiliated Hospital of Xinxiang Medical College from January to June 2005.Their ages ranged from 16 to 55 years and the mean age was (32.7±12.3) years.Among them,54 patients had middle-school education and 42 patients had high-school education.METHODS:A domestic inventory was used to carefully record basically clinical data of each patient.and the inventory included sex,marriage status,educational level,attack styles,home address,home environment,economic status,family history,etc.All data were classified and analyzed in details.In addition,condition of delayed therapy,which determined as the duration over 1 year from onset of psychiatric symptoms to accepted treatment,in each classification was surveyed gradually.MAIN OUTCOME MEASURES:Delayed therapeutic rate and occurent rate of related factors.RESULTS:Among 96 patients,60 patients had delayed therapy,and the delayed therapeutic rate was 62.5%.Influential factors of delayed therapy:Logistic regression analysis demonstrated that regression equation was involved in educational level,family history,attack style and economic status.Meanwhile,the standard regression coefficient was 0.332 1,0.210 1,0.190 3 and 0.101 2. CONCLUSION:Educationallevel,family history,attack style and economic status of patients with dementia praecox are risk factors of delayed therapy. It is of importance for strengthening these factors to interfere and reduce delayed therapeutic rate at an early phase.

Objective To investigate the clinical efficacy and safety of ziprasidone mesylate injection on the acute agitation symptom in mental retardation. Methods The total of 80 patients of mental retardation with acute agitation symptoms were randomly divided into two groups:the treatment group (40 patients) were intra-muscarly given with ziprasidone mesylate injection at the initial dose of 10 mg, 20 mg 4 h later, and 30 mg once on the second day and third day. And the control group (40 patients) were treated with haloperidol injection. The volume dose of haloperidol was 20 mg everyday. Other antipsychotic drugs, antimanic drugs and benzodiazepines were not allowed to be used during the observation, neither does the prophylactic use of drugs against parkinson's disease. Before and 1, 2, 4, 6, 8, 12, 24, 48, 72 h after treatment, the positive and negative scale ( PANSS) reduction rate, the end of the clinical global impression scale ( CGI) were assessed. By the end of the treatment, the adverse reactions symptom, cale ( TESS) was assessed for the safety. Results By the end of treatment PANSS reduction rate was 46. 31% in the test group and 48. 81% in the control group, the clinical improvement rate was 80. 00% in the treatment group and 82. 50% in the control group. No statistically significant difference on efficacy was found between two groups. The side reaction rate in the treatment group was 27. 5%, that in the control group was 40. 0%, there was significant difference ( P<0. 05) between two groups, but the extrapyramidal reaction in the control group was significantly more than that in the treatment group(P<0. 05). Conclusion Ziprasidone mesylate injection is effective on treating the symptoms of mental retardation, in corresponding to the effect of haloperidol injection,and with less extrapyramidal reactions.

Objective To analysis the effect of axial loading to ADC value, FA of lumbar intervetebral discs. Methods Forty five patients with low back pain (age range, 25 to 54 years) were evaluated with MR T2WI, MR T1WI and diffusion tensor imaging (DTI) of the lumbar spine. Following axial loading with 40% to 50% body weight for 10 minutes, a repeat DTI was performed. DTI were obtained by using an echo-planar imaging ( EPI ) sequence, TE 89 ms, TR 2500 ms, b value of 400 s/mm2,6 noncollinear diffusion directions. Scan time was approximately 4 min 10 s. An isotropic ADC map, FA map and bo map were calculated from DTI sequence. The mean ADC value, FA prior to and following axialloading were analyzed with t test and Rank Sum test. Results Forty five patients with 225 discs were evaluated and 223 discs were included in the study except for 2 calcified discs. The Pfirrmann grading results were as following: 100 Grade Ⅱ , 48 Grade Ⅲ, 59 Grade Ⅳ, and 16 Grade Ⅴ. No significant difference existed in the mean ADC value before [ ( 1666 ± 252 ) × 10-3 mm2/s ] and after [ ( 1662 ± 253 ) ×10 -3 mm2/s ] axial loading ( Z = - 1.363, P ＞ 0.05 ), but the mean FA [ ( 301 ± 104 ) × 10 -3, ( 316 ±112) × 10-3 ] value increased ( Z = - 2.794, P ＜ 0.05 ). The paired-samples t test show that the mean ADC value [ ( 1685 ± 190) × 10-3 mm2/s, ( 1624 ± 180) × 10-3mm2/s] of Grade Ⅲ discs decreased after axial loading, t=3.513, P＜0. 05, Grade Ⅲ, Ⅳdiscs mean FA value [(300±87) ×10-3, (326±87) ×10-3 for Grade Ⅲ and (348 ±67) × 10-3, (351 ± 71 ) × 10-3 for Grade Ⅳ ] increased, t = - 2. 210,- 2.006, P ＜ 0.05. No significant difference existed in Grade Ⅱ , Ⅳ and Ⅴ discs ADC value, all the P ＞0.05. No significant difference existed in Grade Ⅱ and Ⅴ discs FA value, both the P ＞ 0.05. Conclusions Short time axial loading mainly affect the mildly degenerated discs, the ADC value decreases and the disc diffusion ability decreases. No obvious change in ADC value or disc diffusion ability existed in the normal and severely degenerated discs.

Objective To explore the efficacy of memantine-assisted deep brain stimulation in adolescents with refractory obsessive-compulsive disorder and its effect on serum neurofactors and inflammatory cytokines.Methods A total of 115 adolescents with refractory obsessive-compulsive disorder were randomly divided into the control group(n = 57)and the study group(n = 58).The control group was treated with sertraline combined with deep brain stimulation for 3 months,while the study group was treated with memantine combined with deep brain stimulation for 3 months.The efficacy,adverse reactions,serum neurofactors(including 5-hydroxytryptamine[5-HT],brain-de-rived neurotrophic factor[BDNF],and glial neurotrophic factor[GDNF]),inflammatory cytokines(including tumor necrosis factor-α[TNF-α],interleukin[IL]-2,and IL-6),mental state,psychosocial functioning,and quality of life before and after treatment were compared between the two groups.Results The total effective rate in the study group was significantly higher than that in the control group(96.55%and 84.21%,P＜0.05).Compared with the control group,the serum 5-HT and BDNF levels at 1-and 3-month post-treatment were signifi-cantly higher in the study group,while the levels of serum GDNF,TNF-α,IL-2,and IL-6 were significantly lower(P＜0.05).The scores of Hamilton Anxiety Scale and Hamilton Depression Scale were significantly lower and the scores of Chinese Version of the Personal and Social Performance Scale,and TDL Quality of Life Assessment Scale were significantly higher in the study group than in the control group(P＜0.05).The incidence of adverse reactions between the two groups were similar(P＞0.05).Conclusion Our results support the efficacy of memantine-assisted deep brain stimulation for refractory obsessive-compulsive disorder in adolescents.In particular,the treatment can regulate neurofactor and inflammatory cytokine levels,relieve anxiety and depression,improved psychosocial function and quality of life,and is safe.
