Objective:To explore the prevalence rate of suicidal ideation and its risk and protective factors in military personnel.Methods:A total of 2071 military personnel were investigated by stratified random cluster sampling in May to August of 2015.The Question 7 of Beck Depression Scale (BDI) was used to test suicide ideation (item 7 score ≥ 1 was dovetailed in suicide ideation group).Family,social demographic and occupational factors were assessed with the self-made general characteristics questionnaire.The data were analyzed with multiple stepwise logistic regression.Results:There were 382 (18.4％) military personnel whose scores of item 7 were ≥1.Family history of suicide (OR =42.97,95％ CI =29.14-63.35),surrounding suicide (OR =2.46,95％ CI =1.75-3.46),drinking (OR =1.64,95％ CI =1.31-2.07) and level of education (OR =1.38,95％ CI =1.01-1.90) were risk factors of suicidal ideation.Protective factors were (OR =0.60,95％ CI =0.50-0.72) and station (OR =0.15,95％ CI =0.03-0.64).Conclusion:It suggests that in suicidal prevention for military,more attention is deserved paying to those military personnel who have family history of suicide,surrounding suicide,drinking habit,and are stationed in remote areas and air force.

Objective: To study the association of dopamine ?-hydroxylase gene 5′ flanking region polymorphism -1021 C→T with attention deficit hyperactivity disorder (ADHD) in Han children. Methods: ADHD was diagnosed according to the DSM-Ⅳ criteria . DNA was extracted and PCR was performed to examine the DBH-1021C→T polymorphism. HHRR was used to test the association of dopamine ?-hydroxylase gene with different subtypes of ADHD. Results: HHRR results showed this polymorphism had a tendency to be associated with the inattention subtype (P=0.067) and the combined subtype (P=0.076). The T allele was the protective factor of the inattentive subtype (P= 0.07), and the risk factor of the combined subtype (P=0.08). After dividing the 292 nuclear families according to sex, DBH-1021C→T polymorphism was found to be associated with the combined subtype (P=0.04) with the T allele as the risk factor (P=0.02). There were no positive findings among the girl nuclear families of ADHD. Conclusion: DBH gene is related to ADHD combined subtype and inattention subtype. The genetic basis of ADHD combined subtype and is inattention is different, and is influenced by sex factor.

T were genotyped by restriction fragment length polymorphism analysis.Transmit/disequilibrium test and haplotype analysis were used to test the association of the three polymorphisms with ADHD comorbid or not comorbid DBD separately.Results:Haplotype T/G/T showed tendency of overtransmission(?2=3.470,P=0.062) to probands of ADHD with DBD, while haplotype C/G/T(?2=4.568,P=0.032) and C/G/C(?2=5.333,P=0.021) were undertransmitted to probands of ADHD without DBD,No biased transmissions of any allele were found in families with probands of ADHD with and without DBD.Conclusion:whether ADHD comorbid DBD or not comorbid DBD makes difference at the level of HTR4 gene polymrohisms.

Objective: To investigate the relationship between two HTR2C gene polymorphisms, that is C 759T and G 697C polymorphisms, and attention deficit hyperactivity disorder (ADHD) comorbid or not comorbid learning disorder (LD). Methods: Blood samples were taken from 189 trios with probands of ADHD comrbid LD (ADHD+LD) and 299 trios with probands of ADHD not comorbid LD (ADHD-LD). DNA was extracted and PCR was performed to amplify the fragments containing both C 759T and G 697C polymorphisms. Aci Ⅰ was used to detect different alleles of the two polymorphisms. Allele based and haplotype based TDT analysis were used to test the association of the two polymorphisms of HTR2C gene and ADHD-LD and ADHD+LD. Results: 759C(? 2= 6.961 , P =0.008), 697G(? 2=8.346, P =0.004), as well as 759C/ 697G haplotype were over transmitted(? 2=9.000, P = 0.002 7), while haplotype 759T/ 697C was under transmitted(? 2= 7.784 , P =0.005 3) to probands with ADHD-LD. No biased transmission of any allele and haplotype were found in families with probands of ADHD+LD. Conclusion: ADHD-LD and ADHD+LD are different at the level of HTR2C gene polymrohisms of C 759T and G 697C. HTR2C is related to ADHD-LD, while not related to ADHD+LD.

Objective To investigate the changes in plasma very long chain fatty acids (VLCFAs),and to explore its relationship with obesity-related index in obese children.Methods One hundred and sixty-six obese children aged 7 to 12 years old were investigated and 148 health children matched with age and sex were selected as control group.Their height,weight,and waist circumference (WC) were measured.The percentage of body fat (PBF) was tested by dual-energy X-ray absorptiometry.Fasting blood triglycerides (TG),total cholesterol (TC),high density lipoprotein-cholesterol (HDL-C),low density lipoprotein-cholesterol (LDL-C) levels,fasting plasma glucose,and fasting insulin (FINS) were determined.The body mass index (BMI),BMI-Z score,waist to height ratio (WHtR),and homeostasis model assessment for insulin resistance (HOMA-IR) were calculated.The plasma VLCFAs were analyzed by gas chromatography-mass spectrometry.Results (1) Compared with normal control children,body weight,BMI,BMI-Z score,WC,WHtR,PBF,TG,TC,LDL-C,FINS,and HOMA-IR in obese children were increased (all P ＜ 0.05),and the level of HDL-C was decreased (P ＜ 0.05).(2) The plasma levels of docosamonoenoic acid (C22 ∶ 1 n-9) and arachidonic acid (C20 ∶ 4n-6) were decreased while the levels of arachicacid (C20 ∶ 0) and eicosapentaenoic acid (C20 ∶ 5n-3) increased in obese children compared to non-obese children.(3) The linear correlation analysis showed that PBF was positively correlated with C20 ∶ 0 and C20 ∶ 5n-3,and negatively correlated with C20 ∶ 4n-6.WHtR was negatively correlated with C22 ∶ 1 n-9 and positively correlated with C20 ∶ 0 (4) The multiple stepwise regression analysis showed that C20 ∶ 0 was the main factor for PBF,and C22 ∶ 1 n-9 and C20 ∶ 0 were the main factors for WHtR.Conclusion The metabolic abnormality of plasma very long chain fatty acids exists in obese children.The changes in C20 ∶ 0,C22 ∶ 1 n-9,and C20 ∶ 5n-3 may be associated with obesity in children.

Objective To evaluate the value of interventional therapy in treatment of iliac compression syndrome (ICS) and subsequent venous thrombosis. Methods Examined by DSA, 125 cases were diagnosed of iliac vein compression and subsequent thrombosis. In 39 cases of ICS ( group 1 ), left: right = 4.6: 1. In 86 cases of ICS complicated with subsequent thrombosis (group 2), left: right = 4.7: 1. The patients of iliac vein compression and compression-related iliac vein stenosis or occlusion without fresh thrombus were treated by percutaneous transluminal angioplasty (PTA) and self-expandable stenting. In those cases with fresh thrombosis the inferior vena cava filter were inserted before thrombosis suction, mechanical thrombus ablation, PTA, stenting and transcatheter thrombolysis. The Chi-square test for comparison of proportions was used to test statistical significance. Results In 39 cases of ICS, 38 cases were treated by PTA and stenting. In 86 cases of deep vein thrombosis complicated with ICS, 83 cases were treated by various interventional therapy. There was no significant difference in the efficiency of intraluminal treatment between the two groups at discharge (97.4% and 96.5%, X2 =0.000,P >0.05) and at 6 months follow-up(96.3% and 90.2%, X2 = 0.266, P > 0.05 ), the difference in excellent-good rate of the two groups was significant at discharge (94.9% and 79.1%, X2=3.879, P <0.05) and at 6 months follow-up (92.6% and 68.6% ,X2 =4.441,P <0.05). Conclusions Interventioual treatment for ICS and secondary thrombosis is safe and effective.
