OBJECTIVETo establish an adolescent violence crime prediction model, and to assess the value of serotonin transporter (5-HTT) gene polymorphism for the assessment and prediction of violent crime.

METHODSInvestigative tools were used to analyze the difference in personality dimensions, social support, coping styles, aggressiveness, impulsivity, and family condition scale between 223 adolescents with violence behavior and 148 adolescents without violence behavior. The distribution of 5-HTT gene polymorphisms (5-HTTLPR and 5-HTTVNTR) was compared between the two groups. The role of 5-HTT gene polymorphism on adolescent personality, impulsion and aggression scale also was also analyzed. Stepwise logistic regression was used to establish a predictive model for adolescent violent crime.

RESULTSSignificant difference was found between the violence group and the control group on multiple dimensions of psychology and environment scales. However, no statistical difference was found with regard to the 5-HTT genotypes and alleles between adolescents with violent behaviors and normal controls. The rate of prediction accuracy was not significantly improved when 5-HTT gene polymorphism was taken into the model.

CONCLUSIONThe violent crime of adolescents was closely related with social and environmental factors. No association was found between 5-HTT polymorphisms and adolescent violence criminal behavior.

Objective As the first robotic da Vinci S surgical system(Intuitive Surgical,Inc,CA) in China,atrial septal de- fect repair(ASD) were performed in 15 patients using the robotic da Vinci S surgical system.Prespectively,we evaluated safety and efficacy in performing both simple and complex ASD repairs.Methods Eligible patients had ASD with mild to moderate pulmonary hypertension.Operative techniques included peripheral cardiopulmanary perfusion,a 2 cm working port only in the forth intercostal space,transthoracic aortic occlusion,and antegrade blood cardioplegia.Transesophageal echocardiograms(TEE) were done intraoper- atively with three-dimensienal reconstructions.Successful repairs were defined.Results Enhanced three-dimensional visualization of ASD allowed safe,dexterous intracardiac tissue manipulation.All patients had successful repairs including direct suturing in 10 cases, as well as pericardial patching in 5 cases.There were no operative deaths,strokes,or device-related complications.One patient was reexplored for bleeding.There were no incisional conversions.The mean cardiopulmonary bypass times and aortic crossclamp times were (109.5?12.6) minutes and (41.2?11.7) minutes.Both robotic repair and total operating times decreased significantly re- spectively.Total ICU length of stay for patients was 1 to 2 days.Conclusion This study shows that the da Vinci S surgical system (intuitive Surgical,lnc) has no limitations in performing ASD repairs.Articulated wrist-like instruments and three-dimensional visual- ization enabled precise tissue telemanipulation.

Objective:To observe the clinical efficacy of treating infantile diarrhea due to spleen deficiency with five-step pediatric tuina of Huxiang school. Methods:Using a randomized controlled trial design, sixty eligible kids with diarrhea due to spleen deficiency were randomized into an observation group and a control group, with 30 cases in each group. The observation group was intervened by the five-step pediatric tuina method of Huxiang school, and the control group received conventional tuina treatment. The intervention was conducted once a day, consecutive 5-day treatment as 1 course, at a 2-day interval between courses, successively for a total of 4 courses. Changes in the primary and secondary symptoms of diarrhea due to spleen deficiency were observed, and the clinical efficacy was evaluated. Results: After treatment, the scores of primary and secondary symptoms and the general score of diarrhea due to spleen deficiency were improved; the improvements in fecal form and frequency, decreased appetite, bloating after meals and fatigue and sluggishness were more significant in the observation group than in the control group. Conclusion: The five-step pediatric tuina method of Huxiang school and conventional tuina both can improve the primary and secondary symptoms in infantile diarrhea due to spleen deficiency, while the former one can produce more significant efficacy.

OBJECTIVETo observe the differences of therapeutic effect of spastic paralysis after stroke between electroacupuncture and acupuncture and explore the mechanism.

METHODSSixty-four cases were randomly divided into an electroacupuncture group (n = 33) and an acupuncture group (n = 31). Both groups were treated with Bobath facilitation techniques and medicine treatments. Quchi (LI 11), Hegu (LI 4), Yanglingquan (GB 34), Sanyinjiao (SP 6), et al. on the affected side were selected in each group. The needle was retained for 30 min, and the manipulation was applied for 1 min in the acupuncture group, and electroacupuncture was added in the electroacupuncture group. Stroke Impairment Assessment Set (SIAS) was adopted to assess the whole function status after sroke, and the contents of glutamate (Glu) and gamma-aminobutyric acid (GABA) in serum and clinical efficacy were observed in the two groups.

RESULTSThe SIAS score increased after treatment as compared with that before treatment in either group (both P < 0.01), and the electroacupuncture group was superior to the acupuncture group (P < 0.01); the content of Glu in blood serum and ratio of Glu/GABA reduced, while the content of GABA in serum increased after treatment as compared with those before treatment in either group (all P < 0.01), but the improvement of above indices were much more apparently in the electroacupuncture group as compared with those in the acupuncture group (P < 0.01, P < 0.05); the total effective rate of 90.9% (30/33) in the electroacupuncture group was superior to that of 83.9% (26/31) in the acupuncture group (P < 0.05).

CONCLUSIONElectroacupuncture can improve therapeutic effect of spastic paralysis after stroke, it's mechanism may be ralated to ajusting the contents of Glu and GABA in serum.

OBJECTIVETo illustrate the early alteration of plasminogen activator inhibitor-1 (PAI-1) in the recipients of hematopoietic stem cell transplantation (HSCT) and explore its clinical significance in transplantation-associated thrombotic complications.

METHODSNinety-five patients undergoing HSCT were enrolled in this study. PAI-1 level and other hemostatic parameters were measured by enzyme linked immunosorbent assay (ELISA) in platelet poor plasma samples from patients on conditioning therapy and then weekly until four weeks after HSCT.

RESULTSSignificant increase in PAI-1 was detected after conditioning treatment, followed by a diminution in the very week on transplantation (week 0), then increased with in time after transplantation. According to the occurrence of transplant-associated complications, patients were classified into four groups: thrombus group \[veno-occlusive disease (VOD) (n = 5), thrombotic microangiopathy (TMA) n = 1\], aGVHD group (n = 29), infection group (n = 19) and non-complication group (n = 41). One of 30 patients (3.3%) was diagnosed as thrombus in the auto-HSCT group, while five of 65 patients (7.7%) did in the allo-HSCT group. PAI-1 level of thrombotic patients was significantly increased compared with non-thrombotic subjects, and the patients without thrombotic complications have higher PAI-1 level in the allo-HSCT group than in auto-HSCT group. All the patients with complications presented with significantly increased PAI-1 compared with those with no complications (P < 0.05). The six patients with thrombotic complications showed extremely elevated PAI-1 \[(62.8 +/- 7.5) microg/L\] compared with that of aGVHD patients \[(45.1 +/- 9.1) microg/L\] or infection patients \[(50.0 +/- 11.2) microg/L\] post-HSCT (P < 0.05).

CONCLUSIONThe increase in plasma PAI-1 may be a specific mark for transplantation-associated thrombotic complications. Increased PAI-1 reflects the development of thrombotic complications. Extreme elevation of PAI-1 contributes to the early diagonsis of VOD and TMA after HSCT.

Introduction:The 2010 targets of the China Hepatitis B Prevention Programme were a prevalence of hepatitis B surface antigen (HBsAg) less than 1.0% for children less than five years old and less than 6.0% for the total population. This survey assessed the prevalence of Hepatitis B infection in Lianyungang, Jiangsu province, China in 2009–2010.Methods:Multistage sampling was used with 2372 subjects among 17 selected villages. Blood specimen collection and testing by enzyme-linked immunosorbnet assay (ELISA) were completed using the following markers for hepatitis infection: HBsAg and antibody to HBsAg (anti-HBs); hepatitis B e antigen (HBeAg) and antibody to HBeAg (anti-HBe); and hepatitis B core antibody (total anti-HBc). The data were analysed with Epi Info, version 3.3.2.Results:The prevalence of HBsAg was 2.4% (95% Confidence Interval [CI]: 1.8–3.0; Adjusted Prevalence [AP] 2.9%); anti-HBs prevalence was 51.1% (95% CI: 49.1–53.1; AP 49.2%) and total anti-HBc prevalence was 41.7% (95% CI: 39.8–43.7; AP 45.5%). The prevalence of HBsAg and total anti-HBc positivity increased from young to older age groups, yet the prevalence of anti-HBs positivity decreased from young to older age groups (P< 0.001 for all). There was no difference in the prevalences of HBsAg and anti-HBs among females and males (P= 0.108 and 0.089), but females had a higher prevalence than males for total anti-HBc positivity (P< 0.001). Discussion: This survey showed that in 2010 the prevalence of HBsAg among children aged less than five years was lower than the national target of 1.0% and that the prevalence of HBsAg for the total population was lower than the national target of 6.0%.

OBJECTIVETo explore the mechanism of cake-separated moxibustion in treatment of hyperlipemia.

METHODSSixty rabbits were randomly divided into 4 groups, a blank group,a model group, a direct moxibustion group and a cake-separated moxibustion group. Hyperlipemia model was developed by high fat diet of cholesterol. Changes of ultrastructures of endothelial cells of the aorta of the rabbit were observed with electron microscope.

RESULTSThe endothelial cells in the cake-separated moxibustion group were more intact, most of them were normal in forms, internal elastic membrane was continuous, their thickness was even, the cells of smooth muscles in the medial membrane were relatively normal, which are similar to those in the blank control group. But the structure of endothelial cells of the aorta in the model group disappeared, in cytoplasm the sedimentation of a great number of lipids can be seen, internal elastic membrane was interrupted, the thickness was uneven, with focal dissolution, the cells of smooth muscle in the medial membrane had sedimentation of lipids, with frothy change.

CONCLUSIONCake-separated moxibustion has a certain protective action on endothelial cells of the aorta in the rabbit of hyperlipemia.
