Autism spectrum disorders (ASD) is a complex,behaviorally defined,mental disorder with uncertain causes although it is more likely caused by the interaction of genetic and environmental factors.ASD's heterogeneity in pathology and phenotype makes it difficult to accurately diagnose individual patients.Therefore,it is an urgent need to develop effective tools for screening susceptible individuals for early diagnosis and treatment.This paper reviews recent neuroimaging and imaging genetic studies of ASD.The existing results indicate that proper combination of multimodal neuroimaging techniques and genetic technology is expected to reveal the pathological mechanism of ASD and might help find objective biomarkers for achieving an early and accurate diagnosis of ASD.

Objective To observe the morphological changes of hairs in two patients with loose anagen hair syndrome.Methods Light microscopy,scanning electron microscopy and transmission electron microscopy were used to observe the morphology of hair shaft and follicles from two patients,including a 3-year-old girl child and her mother,with loose anagen hair syndrome.Results Light microscopy revealed that hair bulb was deformed,hair shaft was distorted,damaged,and even disrupted,and hairs tapered in diameter at their distal end.Scanning electron microscopy showed deformed or distorted hair shaft and wave-like edge of hair cuticles.Transmission electron microscopy revealed that pathological changes were mainly localized in the inner root sheath with vacuolization in both inner and outer root sheath cells.Intercellular adhesion was weak with a decrease or disappearance of desmosomes.Conclusion The pathological changes of hairs are mainly localized in the inner root sheath in patients with loose anagen hair syndrome.

Objective To evaluate neurodevelopmental outcome of very preterm(gestational age ＜ 32 weeks) and very low birth weight infant (VLBWI) (weight ＜ 1 500 g) and to examine the effectiveness of an early intervention program till 12 months corrected age.Methods Seventy followed-up very preterms and VLB-WI in Jinan Maternity and Childcare Hospital were enrolled in this study from January 2012 to and were divided into two groups by birth weight.All infants received 20 items of behavioral neurological assessment at 1 to 12 months corrected age and tested mental and psychomotor development with the use of CDCC at 6,12 months corrected age.The preterms who were abnomal in the 20 items of behavioral neurological assessment would receive early intervention (including kinesitherapy, physiotherapy, cereal circulation therapeutic equipment) by physiotherapists and their parents who received an intervention program training and were strongly encouraged to participate in the intervention sessions.The intervention method was adjusted according to the neurological assessment.The SPSS statistical software package for Windows, version 15.0, was used to run Fisher's exact test and t-test on the data presented,and P value of less than 0.05 was regarded as statistically significant.Results The average gestational age of infants was (30.4 ± 1.8) weeks,and average birth weight (1 463.7 ± 307.5) g.The incidence of extrauterine growth restriction was 57.1％ at first follow-up.The incidence of neurodevelpmental impairment NDI) and cerebral palsy tendency at 6 corrected months were 14.3％ ,8.6％ respectively.At 12 months corrected age,the incidence of NDI decreased to 2.9％ and cerebral palsy to 2.9％.There was significant difference in the incidence of NDI between 6 and 12 corrected months.There was no significant difference in the incidence of psychomotor developmental index ＜ 70, mental developmental index ＜ 70, NDI and cerebral palsy between the two groups.Conclusion The early intervention program can improve VLBWI neurodevelopmental outcomes at 12 months' corrected age and reduce the incidence of cerebral palsy.

Objectives To explore the clinical manifestations, treatment and prognosis of a case of blindness caused by nephrotic syndrome with cerebral venous sinus thrombosis (CVST). Methods The clinical manifestations, diagnosis and treatment of a case of NS with CVST were analyzed. The latest domestic and foreign reseach progresses in treatment for CVST in children were reviewed. Results Epilepsy suddenly appeared with diplopia, binocular vision loss and blindness in anticoagulant therapy for the child with NS. Brain magnetic resonance venography (MRV) suggested CVST. MRV reexam-ined showed that the intracranial thrombosis was completely dissolved after urokinase thrombolysis for one month followed by ineffective heparin anticoagulation. At present, international standards of anticoagulant therapy have been adopted in the treatment for CVST patients. Coagulation function (e.g.APTT) and international standardization ratio were monitored in order to prevent bleeding. Conclusions It is better to perform neural imaging examination early in suspected CVST patients. Anti-coagulation and thrombolytic therapy should be given immediately once the risk of bleeding was excluded and used for 3-6 months.

Objective:To investigate the clinical effect and mechanisms of ceftriaxone combined with ranitidine on the acute pancreatitis.Methods:92 cases of patients with acute pancreatitis were selected and randomly divided into the control group (n=46) and experimental group (n=46),the control group was treated with ceftriaxone,and the experimental group was treated with ranitidine based on the control group,the serum levels of intedeukin-6 (IL-6),c-reactive protein(CRP),platelet activating factor (PAF),superoxide dismutase (SOD),propylene glycol (MDA),gastric secrete element,stomach,heart rate (HR),mean arterial pressure (MAP),and the relief time of clinical manifestation and the clinical efficacy were observed and compared between the two groups.Results:After treatment,the serum levels ofIL-6,CRP,PAF,MDA,gastric secrete element and HR of experimental group were significantly lower than those of the control group (P＜0.05).The serum levels of SOD,stomach motion element and MAP of experimental group were higher than those of the control group (P＜0.05).The relief time of clinical manifestation and total efficiency of experimental group were better than those of the control group (P＜0.05).Conclusions:Ceftriaxone combined with ranitidine could effectively enhance the clinical efficacy of acute pancreatitis,which might be related to the anti-oxidation and anti-inflammation.

OBJECTIVE To investigate the incidence of nosocomial infection (NI) in our hospital,analyze the related factors,and provide theoretical basis for better prevention and control of NI. METHODS A total of 19 203 inpatients from Dec 2006 to Nov 2007 were retrospectively analyzed,of which 387 inpatients suffering from NI. RESULTS The rate of NI was 2.02%,the highest infected rate was in ICU (24.32%). The main infection site was respiratory tract (57.58%). The species were predominated by Gram-negatives (52.00%). CONCLUSIONS The incidence of NI is connected with factors such as age,underlying diseases,invasive operation and the misusage of antibiotics.
