ACKGROUND:Autism is a kind of neurobiological disease.The increase of plasma concentration of 5 hydroxytryptamine(5 HT) is considered to be one of study results,which is the most definite and has the best repetition,for the biological investigation of autism. Whether the season of birth and maternal mood during pregnancy are correlated with the occurrence of autism? OBJECTIVE:To compare the differences of the plasma concentration of 5 HT,season of birth and the maternal mood during pregnancy between autistic and normal children,and probe into the cause of increased 5 HT in autism. DESIGN:An observational comparative study taking autistic and normal children as the subjects. SETTINGS:A clinical psychological department of a university hospital;Mental Health Institute of the Xiangya Second Hospital;A rehabilitation center for dumb children of city grade. PARTICIPANTS:Children in the autistic group(n=54),who were in accordance with the diagnostic criteria of autism in Diagnostic and Statistical Manual of Mental Disorders Fourth Edition(DSM IV) and had the total score of social adaptive ability scale(SAAS) over 40, were selected from the Outpatient Clinic for Children of the Mental Health Institute,Xiangya Second Hospital of Central South University and the training class of autism of Shenzhen Special Education School;Children in the normal control group,who had no obvious somatic and neurological diseases,and developing delay detected by physical,neurological and mental status examinations, rough detection of developing level,were selected from the primary school and kindergarten in Changsha and Shenzhen cities. INTERVENTIONS:The plasma level of 5 HT was examined, season of birth and maternal mood during pregnancy were investigated in autistic and normal children.The children with autism were accessed with SAAS. MAIN OUTCOME MEASURES:The plasma level of 5 HT,the season of birth and the maternal mood during pregnancy in both groups. RESULTS:The score of SAAS in children with autism was 67.65± 1.67.The plasma level of 5 HT was(0.78± 0.32) μ mol/L in the autistic group,which was significantly higher than that in the normal control group [(0.62± 0.16) μ mol/L](t=3.17,P=0.002). There were 17 children with autism had increased 5 HT.Compare with normal children,most children with autism were born in winter and spring,and their mother had obvious mood problems during pregnancy. CONCLUSION:The 5 HT level is higher in children with autism than in normal children.Most children with autism were born in winter and spring,and their mother had obvious emotional problems during pregnancy.There are phase of high functioning of 5 HT in mother in key period of fetus cerebra development that may be one of the causes of hyperserotonemia in autism,and that is possibly one of the etiologies of autism.

This study was aimed to evaluate effect of Qinghua Granules (QHG) on glycometabolism, pancreatic islet function and oxidative stress in type-2 diabetics with heat syndrome. A total of 60 cases of type-2 diabetics with heat syndrome (according to the Syndrome Element Syndrome Differentiation) were enrolled in the clinic of the Department of Endocrinology and Metabolism, Shuguang Hospital Affiliated to Shanghai University of Tradi-tional Chinese Medicine. The average age of enrolled cases was (57.9 ± 6.9) years. Enrolled cases were randomly divided into the treatment group and the control group. The original hypoglycemic plan was continued to use. In the treatment group, QHG was administrated. And in the control group, placebo was given. The administration dosage in both groups was one package per day. The treatment course was 12 weeks. The fasting and postpran-dial (120 min after standard meal) blood samples before and after medication were collected. The main evalua-tion indexes were fasting plasma glucose (FPG), postprandial plasma glucose (PPG) and hemoglobin A1c (HbA1c). The secondary evaluation indexes were homeostasis model assessment (HOMA2-%B, HOMA2-%S, HOMA2%-IR), superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), maleic dialdehyde (MDA), total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL) and low-density lipoprotein (LDL). The anal-ysis of variance was used in the comparison of efficacy between two groups . The results showed that HbA1c in the treatment group was obviously reduced, and HOMA2-%B was obviously increased. There was no significant changes in the control group ( P = 0 . 044 , P = 0 . 016 ) . In the treatment group , SOD increased obviously , MDA reduced obviously. There was no significant change in the control group. There was difference b etween two groups (P = 0.011, P = 0.049). There was no change on blood lipids or other evaluation indexes. It was conclud-ed that QHG is effective in the improvement of glycometabolism, islet β-cell functions and oxidative stress in type-2 diabetics with heat syndrome .

Objective：To explore the characteristics of behavioral problems and self-concept level in children with attention deficit hyperactivity disorder(ADHD)accompanying anxiety disorder.Methods：With stratified random sampling method,a sampling survey was made in 9495 children(aged 5～17 years)from 6 regions of Hunan province together.Using the two stage epidemiologic research method,three groups,including control group(214 cases),pure ADHD(219 cases)and ADHD accompanying anxiety disorder(111 cases)were determined as the subjects.All the subjects completed the Children's Self-Concept Scale(CSCS),and the Achenbach Child Behavior Checklist(CBCL)was completed by their parents.Results：(1)Compared to the control group,the pure ADHD group scored higher in CBCL [e.g.,the total score:(30.35±24.32)vs.(16.97±14.86)],and scored lower in CSCS [e.g.,total score:(50.85±9.98)vs.(57.46±10.80),P<0.05].(2)Compared to the control group,children with ADHD accompanying anxiety disorder scored higher in CBCL [e.g.,total score:(41.66±28.07),P<0.01],and in CSCS except physical activities(Ps<0.05).(3)Compared to the pure ADHD group,ADHD accompanying anxiety disorder group scored higher in CBCL and lower in CSCS[behavior:(10.44±3.17)vs.(11.55±2.80);anxiety:(8.06±2.61)vs.(9.21±2.61),gregariousness:(7.42±2.22)vs.(8.16±1.89);total score:(47.25±9.93)vs.(50.85±9.98);Ps<0.05].Conclusion：ADHD children have more behavioral problems and lower level of self-concept than normal children,and children with ADHD accompanying anxiety disorder have more prominent presence of behavioral problems and lower self-concept rating than children with pure ADHD.

AIM: The roles of Cl-channels in regulatory volume decrease (RVD), cell proliferation and cell cycle progression in nasopharyngeal carcinoma cells (CNE-2Z) were investigated. METHODS: Image analysis of living cells was used to detect the volume changes following exposure to hypotonic solutions. Cell viability was determined by the trypan blue assay. MTT method was applied to detected cell proliferation. The effect of the blocker on the cell cycle distribution was monitored by the flow cytometry. RESULTS: 5-nitro-2-(3-phenylpropylamino) benzoic acid (NPPB) inhibited RVD and cell proliferation in a dose-dependent manner. NPPB at the concentration of 100 ?mol/L arrested cells in G 1 phase (G 1 population increased from 54% to 71% at 48 h after treatments), but did not significantly alter cell viability. CONCLUSION: Block of chloride channels suppressed cell proliferation by arresting cells in G 1 phase. The results suggest that activation of Cl-channels and RVD is necessary for facilitating cells to proceed to the S phase from G 1 phase and maintaining cell proliferation.

Objective:To study the biological role and related mechanism of autophagy in acute lung injury (ALI) of hemorrhagic shock mice.Methods:According to random number table method, wild-type male C57BL/6 mice were divided into control group, ALI group, rapamycin group and 3-methyladenine (3-MA) group, with 8 mice in each group. Light chain 3 (LC3) gene knockout mice with C57BL/6 background were divided into LC3 knockout group and LC3 knockout+ALI group, with 8 mice in each group. Control group, ALI group, LC3 knockout group, LC3 knockout+ALI group were intraperitoneally injected with 2 mL/kg normal saline, rapamycin group was intraperitoneally injected with 3 mg/kg autophagy activator rapamycin, 3-MA group was intraperitoneally injected with 15 mg/kg autophagy inhibitor 3-MA, all of which were given for 3 consecutive days. 2 hours after the last administration, the hemorrhagic shock induced ALI model was established. 24 hours after modeling, the lung index was calculated. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of lung tissue and lung injury score was performed. The expressions of autophagy genes LC3-Ⅱ/LC3-Ⅰ and Beclin-1 in lung tissue were detected by Western blotting. The contents of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and malondialdehyde (MDA) in lung tissue were detected according to the steps of the kit.Results:Compared with the control group, the lung tissue structure was destroyed and exudation increased, lung index, lung injury score, the expressions of LC3-Ⅱ/LC3-Ⅰ, Beclin-1, and the contents of TNF-α, IL-6 and MDA in lung tissue significantly increased in the ALI group. Compared with the ALI group, the structural damage and exudation of lung tissue were reduced in the rapamycin group, lung index, lung injury score and the contents of TNF-α, IL-6 and MDA in lung tissue decreased, while the expressions of LC3-Ⅱ/LC3-Ⅰ and Beclin-1 in lung tissue increased [lung index: (7.56±0.39)% vs. (9.12±0.59)%, lung injury score: 3.04±0.58 vs. 9.32±2.14, TNF-α (ng/mg): 1.85±0.32 vs. 3.51±0.62, IL-6 (ng/mg): 1.61±0.32 vs. 2.52±0.44, MDA (nmol/mg): 1.03±0.16 vs. 1.88±0.24, LC3-Ⅱ/LC3-Ⅰ: 1.21±0.12 vs. 0.39±0.05, Beclin-1/β-actin: 1.10±0.12 vs. 0.58±0.06, all P < 0.05], while lung tissue structure damage was aggravated and exudation was further increased in the 3-MA group, lung index, lung injury score and the contents of TNF-α, IL-6 and MDA in lung tissue increased, the expressions of LC3-Ⅱ/LC3-Ⅰ and Beclin-1 in lung tissue decreased [lung index: (10.44±0.62)% vs. (9.12±0.59)%, lung injury score: 11.59±2.28 vs. 9.32±2.14, TNF-α (ng/mg): 4.77±0.71 vs. 3.51±0.62, IL-6 (ng/mg): 3.44±0.52 vs. 2.52±0.44, MDA (nmol/mg): 2.71±0.42 vs. 1.88±0.24, LC3-Ⅱ/LC3-Ⅰ: 0.25±0.04 vs. 0.39±0.05, Beclin-1/β-actin: 0.21±0.03 vs. 0.58±0.06, all P < 0.05]. Lung index, lung injury score and the contents of TNF-α, IL-6 and MDA in lung tissue of LC3 knockout ALI mice were higher than those of wild-type ALI mice [lung index: (10.44±0.75)% vs. (9.12±0.59)%, lung injury score: 12.41±2.86 vs. 9.32±2.14, TNF-α (ng/mg): 4.85±0.72 vs. 3.51±0.62, IL-6 (ng/mg): 3.28±0.51 vs. 2.52±0.44, MDA (nmol/mg): 2.75±0.41 vs. 1.88±0.24, all P < 0.05].
