Objective: To investigate the status and influencing factors of substance-induced psychotic disorders in residents over 18 years old in Hebei Province, and to provide evidence for the prevention and control of substance-induced psychotic disorders. Methods: Using multi-stage stratified random sampling method, the permanent residents aged 18 years and over were selected from urban and rural areas in Hebei Province. The demographic data was collected, the 12-Item General Health Questionnaire ( GHQ-12 ) and eight risk factors about mental disorder questionnaire were used to find out mental disorders. The multivariate logistic regression model was conducted to analyze the influencing factor for substance-induced psychotic disorders. Results: A total of 23 675 questionnaires were sent out, 20 884 were valid ( 88.20% ).The weighted lifetime prevalence rates of substance-induced psychotic disorders, alcohol-related disorders, sedatives/hypnotics/anti-anxiety disorders and other substance-induced psychotic disorders were 6.20%, 5.93%, 0.24% and 0.04%, respectively. Multivariate logistic regression analysis showed that age ( 35-<45, OR=1.582, 95%CI: 1.091-2.292; 45-<60, OR=2.185, 95%CI: 1.524-3.132; ≥60, OR=2.061, 95%CI: 1.422-2.986 ), males ( OR=10.832, 95%CI: 8.265-14.196 ), urban area (OR=1.431, 95%CI: 1.202-1.703 ), non-poor family ( OR=2.291, 95%CI: 1.652-3.177 ), physical diseases ( OR=2.028, 95%CI: 1.678-2.452 ) and genetic history ( OR=1.574, 95%CI:1.181-2.098 ) were the influencing factors for substance-induced psychotic disorders. Conclusion The lifetime prevalence of substance-induced psychotic disorders among residents aged 18 years and over in Hebei Province is 6.20%, which is mainly related to age, gender, region, family economic situation, physical disease history and genetic history.

AIM: To identify the effect of alkylating agent N-methyl-N'- nitro-N-nitrosoguanidine (MNNG) with low concentration on JNK/SAPK and p38MAPK and the origins of JNK/SAPK and p38MAPK cascade.METHODS: p38 and JNK kinase activity were detected by immunoprecipitation and Western immunoblotting in intact and enucleated Vero cells.RESULTS: With the same experimental conditions, low concentration of MNNG inhibited JNK kinase in both intact cell and enucleated Vero cell. MNNG activated p38 kinase in intact cell while no effect on p38 kinase in enucleated cell was observed.CONCLUSION: Inhibition of JNK/SAPK by low concentration of MNNG was independ of a nuclear signal while MNNG activation of p38MAPK may depend on a nuclear signal.

Objective To research in death reason and corresponding nursing measures to provide evidence for clinical nursing and medical service through analysis of death data of mental disorder inpa-tients. Methods Data of 128 mental disorder inpatients died in hospital were reviewed and analyzed.Results Among death reasons of these patients:physical disease (50.8%)was the most common death rea-son,followed by accidents (19.5%) and sudden death (19.5%).Death happened on first admission was 91 cases (71.1%).Death happened within 10 days of hospitalization was 60 cases (46.9%).The occurrence of death was common on nighttime, after lunch and meals time. Conclusions Physical disease,accidents and sudden death were main death reasons of mental disorder inpatients.Medical workers should pay atten-tion to patients who were on first admission or within 10 days of hospitalization and strengthen nursing work on special time.

AIM: To explore the effect of low concentration of N-methyl-N-nitro-N-nitroguanidine (MNNG) on p38MAPK, and the function of glutathione (GSH) on p38MAPK. METHODS: Western blotting was applied to detect the p38MAPK phosphorylation in MNNG treatment group and control group. To study the effect of GSH on MNNG-regulated p38MAPK activity, the intracellular GSH level was reduced by pretreatment of L-buthionine-S, R-sulfoximine (BSO). Assuming the absorbance of band in control group as 1.0, the relative P/T values of the treatment groups were calculated, with the “P” served as absorbance values of phospho-p38MAPK and the “T” as absorbance values of total p38MAPK. RESULTS: In BSO pretreated groups,the relative P/T in samples treated with MNNG for 2.5 h was 0.84, and became 2.19 with 3 h more incubation in the fresh medium. CONCLUSION: GSH deletion increases the activity of p38MAPK in MNNG treatment.

Objective To study the relationship between serum HBV DNA level and apoptosis of peripheral blood mononuclear cells (PBMC) , and the relationship between serum HBV DNA level and the activity of caspase-8 in the patients with chronic hepatitis B (CHB). Method 30 CHB patients were selected as experimental group, and it was divided into three subgroups according to the serum HBV DNA level, subgroup A (high serum HBVDNA), subgroup B (medium serum HBVDNA), and subgroup C (low serum HBVDNA). 10 healthy adults were random selected as control group. PBMC were isolated from two groups by separating medium of lymphocytic cell and culturing it with phytohemagglutinin (PHA) in vitro for 72 hours. The PBMC was stained with PI and the apoptosis was assayed with flow cytometry. At the same time, the aetivity of caspase-8 of PBMC was assayed by color matching. Results The apoptosis rate of PBMC of experimental group ( 26. 88 ± 7.37 ) % were higher than that of the control group ( 14. 95 ±2. 53)% ( P <0. 01 ). In the experimental group, the apoptosis rate of PBMC of subgroups A, B and C showed decreasing order (34. 75 ± 4. 59)%, (25.63 ± 3.55 )%, ( 18. 91 ± 3. 81 )%. The activity of caspase-8 of experimental group 2. 99 ±0. 82 were higher than that of the control group 1.43 ±0. 91 ( P <0. 01 ). The activity of caspase-8 of subgroup A, B and C showed the same decreasing order: 3. 87 ±0. 35,2. 95 ± 0. 36, 1.95 ± 0. 29. There was a positive correlation between the apoptosis level of PBMC and the activity of caspase-8 in experimen tal group ( r = 0. 610, P < 0. 01 ). Conclusion AICD of PBMC was found in patients with CHB. The activity of caspase-8 increased in that process, and it may participate in the transduction of apoptosis signal. Serum HBV DNA level was related with the apoptosis rate of PBMC and the activity of caspase-8, and it may be one of the reasons of apoptosis in PBMC.

BACKGROUND: By detecting vasoactive substances of experimental rats with myocardial ischemia, pharmacological mechanism of xiongbitong was studied in this research.OBJECTIVE: To observe the effect of xiongbitong capsule on release of vasoactive substances of rats with myocardial ischemia.DESIGN: A completely randomized controlled study.SETTING: Department of Health, Weifang Medical College; Department of Physiology, Department of Immunity and Pathogenic Biology, Department of Internal Medicine, Weifang College of Traditional Chinese Medicine.MATERIALS: The experiment had been carried out in the Laboratory of Physiology of Weifang Medical College from January 2003 to June 2003.The cleansing grade 30 Wistar rats, 6-8 months, of either sex, were randomly divided into three groups:namely, normal control group, model control group and model group of treatment with xiongbitong capsule.METHODS: [1] At 12 hours before making model, rats of model treatment group were irrigated with xiongbitong capsule 2.5 g/kg (a capsule contents dried medicinal herbs 1 g), which consists of tuckahoe, rhizoma, immature bitter orange, exocarpium citri grandis, rhizoma acori tatarinowi, moxibustion, dalbergia wood, mongolian snakegourd, curcuma root, red sage root,root of donopsis pilosula, ilyturf root, ophiopogon, polygala root, date kernel etc., and dissolved in 4 mL physiological saline. AT ten hours after making model, they were irrigated with same dose once more. The rats of normal control group and model control group were irrigated with the same dose physiological saline at the same time. One hour after the first irrigation, the animal models of myocardial ischemia of rats of model control group and model treatment group were established by injecting vitriol isoprenaline according to 10 mg/kg subcutaneously. [2] Endothelin (ET), calcitonin generelates peptide (CGRP), 6-keto-prostaglandin Fl alpha (6-keto-PGF1α) and thromboxane B2 (TXB2) in the plasma of rats were detected according to the explanation of Institute of Beijing East Asia Immune Technique. [3] The analysis of variance and q test were used for comparing between groups.MAIN OUTCOME MEASURES: Contents of vasoactive substances in the plasma of rats in each experimental group.RESULTS: The date of all thirty rats was entered the final analysis. [1]The contents of (TXB2) and ET, TXB2/6-Keto-PGF1α, ET/CGRP: Compared with the model group, the normal control group and model treatment group reduced obviously (q=2.99-9.87, P ＜ 0.05-0.01). [2] The contents of 6-Ke-to-PGF1α and CGRP: Compared with the model group, the normal control group and model treatment group increased obviously [(603.3 ±90.6),(190.0±64.2) ng/L; (560.7±111.1), (174.9±41.4) ng/L; (380.4±705),(114.9±36.4) ng/L, q=3.88-7.64, P ＜ 0.05-0.01].CONCLUSION: Xiongbitong capsule may suppress unusual release of vasoactive material at myocardial ischemia area obviously, increase the content of expanding the blood vessel material, and correct out-of-balance of content of important TXB2, 6-keto-PGF1α, XTB and CGRP in the body.

The effect of triptolide (TP) on the expression of receptor activator of nuclear factor-kappaB ligand (RANKL) and osteoprotegerin (OPG) was explored in rat adjuvant induced arthritis (AA). AA was induced in Wistar rats. Arthritis rats were treated with TP and methotrexate (MTX) at the onset (day 9) of arthritis. On the peak of arthritis (day 24), the expression of RANKL and OPG protein in the joints and RANKL mRNA in peripheral blood mononuclear cells (PBMC) was detected. TNF-alpha and IL-1beta levels in peripheral blood were determined. Bone erosion scores were also evaluated. The results showed that bone erosion scores in TP and MTX groups were lower than in AA group (P < 0.01); The expression levels of RANKL in the synovium (P < 0.01) and bone (P < 0.05), and OPG level in synovium (P < 0.05) were lower in TP group than in AA group (P < 0.05). In TP group, the expression levels of RANKL mRNA and TNF-alpha, IL-1beta in PBMC were lower than in AA group (all P < 0.01). It was concluded that TP could inhibit rat adjuvant arthritis bone erosion by suppressing the expression of RANKL.

Objective To compare the differences of prescription pattern, adverse events, economic burden and drug-use adherence between preferred mood stabilizers and preferred antipsychotics in patients with bipolar disorder. Methods We investigated 240 cases of patients with bipolar disorder from 39 mental health institutions in 11 cities in Hebei province. The self-made questionnaire was used to investigate the demographic information, disease characteris-tics, prescription pattern and medical expense. The clinical global impression scale-severity of illness (CGI-SI) was used to assess the disease severity. The treatment emergent symptom scale (TESS) was used to assess the adverse drug reac-tions. The medication adherence rating scale (MARS) was used to assess drug therapy compliance in patients. Results One hundred fifty-two patients (63.3%) used antipsychotics as the first choice (antipsychotics group), 88 patients (36.7%) used mood stabilizers as the first choice (mood stabilizers group). The number of patients in-patient (90.1%vs. 76.1%), patients with psychotic symptom (27.0%vs. 11.4%), incidences of adverse events (46.1%vs. 31.8%), drug daily cost (me-dians 12.00 yuan vs. 8.37 yuan) and drug total cost (medians 344.61 yuan vs. 144.64 yuan) were larger in antipsychotics group than in mood stabilizers group (P<0.05). There was no significant difference between two groups in pattern of pre-scription, severity of adverse events and total scores of MARS (P>0.05). Conclusion The bipolar disorder patients more frequently use antipsychotics as the first choice in Hebei province. The use of antipsychotics does not alter the combina-tion medication pattern. In addition, antipsychotics cause a higher incidence of adverse events and heavier economic bur-den compared with mood stabilizers, suggesting that mood stabilizers should be the first choice to bipolar disorder.
