BACKGROUND: Psychological behaviors play an important role in children accidental injury, and children with a tendency of accidental injury display specific psychological properties in characters and behaviors.OBJECTIVE: To investigate the difference of personality and behavioral characters between normal children and children with a tendency of accidental injury.DESIGN: Case controlled analysis based on suffered children and normal hildren.SETTING: Department of pediatric in a civic hospital.PARTICIPANTS: Totally 131 accidental injured children aged from 7 to 11 years were admitted at Tengzhou Civic center hospital between January and December 2001. Those with congenital intellectual disturbance and brain trauma were excluded and the rest 89 cases were asked to fill questionnaire, 8 were removed from the study due to unintegrated data and 81pieces of integral data were collected (reclaiming rate of 91.01%), including 50 males and 31 females with the mean age of (8.59±1.86) years, the intelligence quotient was(96±15) determined by Peabody picture vocabulary test(PPVT); and 81 children in control group matched in age and sex were selected from healthy children of school age without injury history and similar in some aspects, such as parents' culture degree, economic condition, educational state and the economic and culture state of inhabitancy with control group, including 45 males and 36 females with the mean age of (8.92±1.73) years, the intelligence quotient was(98±18) by PPVT. Two groups were matched in sex, age and IQ(P＞0.05).METHODS: Eysenck personality questionnaire and Achenback children behavioral rating scale(parents rating scale) were used.RESULTS: Data of two groups with 81 questionnaires in each entered into the final analysis without loss. ① Scores for psychoticisim, introverted and extroverted character and neurological quality in Esonk personality question naire were(50. 01±10.58, 55.19±12.1, 57.35±10.12) in injury group, higher than corresponding(45.63±13.81, 48.09±6.49, 50. 01±10.39)in control group( t = 2. 27-4.65, P＜0.05) . Scores for modified rating scale was(49.42±10.42) in control group, higher than(39.65±13.03)in injury group( P＜0.001); ② The median was found higher in hyperactivity, aggression, violation of discipline, bad communication, split anxiety,depression and physical complaint in boys of injury group; as well as in hyperactivity, cruelty, aggression, depression, physical complaint, social retreat, violation of law in girls of injury group, comparing to control group(P＜0.001); ③ Positive behavioral detecting rate of injury group was 32.09% (26/81), higher than 11.11% (9/81) of control group(P ＜0.001), OR was 3.78, and 95% CI was 1.66-8.59. Behavioral factors was proved of lower sensitivity(32. 1% ) with specificity of 88.9% and higher prognostic value of 74. 3%; ④ The mean score for Achenback children behavioral rating scale was(39. 84±10. 99) in boy which was obviously higher than(34.26 ± 10.43) in girls of injury group( P ＜0.05). The edian for violation of discipline and aggression in boys and depression in girls were significantly higher than the opposite sex group(P＜0.05 or 0.01) . The mean score for Achenback children behavioral rating scale was (37.62±11.03) in injury group, which were obviously higher than (17.77±12.12) of control group( P＜0.01) . ⑤Results of multiple factors Logistic analysis revealed that the risk factors for accidental injury included: aggression, hyperactivity and iolation of discipline in boys and aggression, violation of discipline and depression in girls.CONCLUSION: Children with a tendency of accidental injury has obvious ehavioral problems, behavioral factors were proved of lower sensitivity, but of igher specific positive prognostic value. Both boys and girls displayed speific characters in aggression and violation of discipline, and lack of pretendng capability comparing to normal children, thereby liable to response in on-rational manner.

Objective To evaluate the clinical effect of breast implant on congenital mammary dysplasia with mild pigeon chest deformity. Methods From January 2003 to July 2009,10 cases of female mammary dysplasia (between 20 to 31 years of age) underwent breast implant surgery. Subpectoral placement and transaxillary incision were selected. The surgeon marked the range of the operation on the skin, made a 3-4 cm incision in the armpit, separated the tissue until the pectoral lateral margin, cut the pecto-ralis fascia and bluntly created a suitable pocket under the pectoralis major for the implant. After the implant was placed in the pocket, the incision was closed. Results Ten cases of breast implant surgery did not pose the complications of local skin necrosis, infection, implant shift, heart and lungs dysfunction after one year follow-up. The appearance of anterior chest wall deformity was markedly improved. Conclusions The application of breast implant surgery in the treatment of congenital mammary dysplasia with mild pigeon chest deformity should be promoted, because of the double surgical effect of easy performing, minimal surgical damage, perfect breast shape and concealed deformity.

In this study Na2HPO4-Ca(NO3)2 system was used to synthesize hydroxyapatite (HA). Its synthetical method was simple and low in cost. With the physical-chemical characteristic observation and the animal experimentit was proved that HA was pure, with pores ranging from 20 to 200 ?m in diameter.The chemical structure of HA was similar to that of inorganic part of bones.An investigation of the histological changes and osteogenetic effectiveness of HA implanted was conducted and the mechanism of HA osteogenetic effectiveness is discussed. The study will provide scientific basis for the clinical use of HA as bone graft substitute.

Objective To evaluate the clinical effect of treatment for deep burn wound on finger by proper digital artery flap.Methods From March 2013 to October 2016, 24 patients with deep burn wound on finger were treated by proper digital artery flap.Postoperative observation included wound repair, flap survival, complications and functional recovery of fingers.Results All the 24 flaps survived and no necrosis happened.The marginal abnormal circulation of flap occurred in only 5 cases, which cured by dress changing.All flaps kept well in contour, skin color, temperature and texture.Movement function of donor and recipient fingers was nearly normal.Conclusion Proper digital artery flap avoided the deficiencies distant pedicled flap, so it is a favorite choice for digital soft tissue defect caused by deep burn injury.

A Cleanert Alumina-N-SPE column (0.5 g/6 mL) chromatograpy with 5 mL of chloroform-methanol (7: 3) as eluent, instead of aluminum oxide column (100-200 mesh, 5 g, 1 cm) chromatograpy eluted successively with chloroform and the chloroform-methanol (7:3) (20 mL each), was applied to enrich matrine and oxymatrine in Sophora flavescens. Also, the optimization of the HPLC determination conditions with acetonitrile-ethanol absolute-3% phosphoric acid solution (84: 6: 10) as mobile phase, instead of acetonitrile-ethanol absolute -3% Phosphoric acid solution (80: 10: 10) recorded in Chinese Pharmacopoeia 2010 Edition, was more suitable for determination of matrine and oxymatrine in S. flavescens. This method has advantage of reducing sample handling time and solvent volume and increasing the accuracy and feasibility, which can simplify the procedure for determination of matrine and oxymatrine in S. flavescens.

The newly emerged Middle East respiratory syndrome coronavirus (MERS-CoV) is a highly pathogenic respiratory virus with pathogenic mechanisms that may be driven by innate immune pathways. The goal of this study is to characterize the expression of the structural (S, E, M, N) and accessory (ORF 3, ORF 4a, ORF 4b, ORF 5) proteins of MERS-CoV and to determine whether any of these proteins acts as an interferon antagonist. Individual structural and accessory protein-coding plasmids with an N-terminal HA tag were constructed and transiently transfected into cells, and their native expression and subcellular localization were assessed using Wes tern blotting and indirect immunofluorescence. While ORF 4b demonstrated majorly nuclear localization, all of the other proteins demonstrated cytoplasmic localization. In addition, for the first time, our experiments revealed that the M, ORF 4a, ORF 4b, and ORF 5 proteins are potent interferon antagonists. Further examination revealed that the ORF 4a protein of MERS-CoV has the most potential to counteract the antiviral effects of IFN via the inhibition of both the interferon production (IFN-β promoter activity, IRF-3/7 and NF-κB activation) and ISRE promoter element signaling pathways. Together, our results provide new insights into the function and pathogenic role of the structural and accessory proteins of MERS-CoV.

Objective: To evaluate the immunogenicity of high-dose inactivated quadrivalent influenza serial vaccines (split virion) for elderly people. Methods: Immunogenicity assays on mouse as research animal model with inactivated quadrivalent influenza serial vaccines (split virion) were carried out. Then rates of seroconversion and geometric mean hemagglutination inhibition titers (GMTs) at day 21 after the last vaccination among those who received high-dose (HD) A+ B influenza vaccine, were compared with those who received other vaccines by hemagglutination inhibition (HAI) test. Results: The result of HAI test showed in HD serial vaccine groups, GMTs for all kinds of HA in the two HD serial vaccine groups were significantly different from that of the two SD serial vaccine groups, respectively (P<0.0001), but not the titers for A3 in one B dose first group. Further- more, GMTs for strain A in one B dose first groups were significantly higher than that of one B dose first groups in both HD and SD groups, and vice versa in the GMTs for strain B. The result of the assay of the impact of different immunization intervals of HD serial influenza vaccine on immunogenicity indicated that the immunity responses in 7 or 10 d groups were higher than that in 3 d group. Conclusions It is a new method to prevent the flu for elderly by HD A+ B serial influenza vaccine, whose HA dose per immunization was reduced into two injections, worked best when the immunization interval was 7-10 d. The protective immunity can be improved by selecting immune procedure of the serial vaccine according to the epidemic type surveillance of influenza virus A and B strains.
