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 discuss the optimalselection of the puncture path in performing CT-guided pericardial drainage,and to evaluate its clinical feasibility and safety.Methods A total of 114 patients with pericardial effusion,who were admitted to authors' hospital during the period from May 2013 to March 2016,were enrolledin this study.The appropriate body position and suitable needle-puncturing route were selected,and CT-guided pericardial drainage with Seldinger'stechnique was performed.Results Successful puncturing and catheter drainage was obtained in all 114 patients,no any serious complication occurred.The time used for manipulation was 18-30 min.Conclusion The use of right puncture path is of great importance for the performance of CT-guided pericardial drainage for pericardial effusion,this technique is highly feasible and safe for relieving the clinical symptoms of pericardial tamponade.

The population of bacterial physiological groups in tomato with different resistant to Ralstonia solanacearum was studied. The results suggested that endophytic bacterial communities and population in tomato variety changed with different resistant cultivars, different stages of tomato and seasons. It was con-ducted that the amount of ammoniation bacteria was the highest among the seven physiological bacterial groups. There were more ammoniation bacteria in high resistant tomato cultivars than that in high suscepti-ble cultivars. It may indicate that ammoniation bacteria played a key role in the occurrence of tomato bacte-rial wilt. In addition, the total amount of physiological bacteria in resistant cultivars was more than that in susceptible cultivars in different stages of tomato, and the tendency of changing displayed fluctuation. The average level of quantities of the ammoniation bacteria, nitrifiers bacteria, erobic nitogenfixing bacteria and desulphate reducer bacteria in summer were higher than that in winter, while the population of the sulphate reduced bacteria in winter was higher than that in summer. Furthermore, the amount of anaerobic bacteria was the least among them.

Objective To observe the differences of cerebral activation pattern with resting state functional magnetic resonance imaging (rs-fMRI) between patients with spasmodic torticollis (ST) and healthy controls,thus to investigate the pathogenesis of ST.Methods Nineteen ST patients and 21 age,sex and education-matched healthy controls,recruited from the Department of Neurology,First Affiliated Hospital of Guangxi Medical University between November 2012 and January 2016,were included in this study.rs-fMRI and factional amplitude of low frequency fluctuation (fALFF) were used to obtain differences between patients with ST and healthy controls,and correlative analysis was made on fALFF values of abnormal brain regions and ST patients' symptom severity (Tsui scores).Results Compared with healthy controls,patients with ST had significantly increased fALFF in the left cerebellum and significantly decreased fALFF in the left posterior cingulate cortex/precuneus,right posterior cingulate cortex/precuneus,left middle temporal gyrus,right angular gyrus,left post-central gyrus,right supplementary motor area (t =-5.714-5.920,P ＜0.01),and abnormal brain regions' fALFF values had no correlation with patients' age of onset,disease course,symptom severity (P ＞ 0.05).Conclusion Abnormal sensorimotor area,default mode network and cerebellum dysfunction may play a role in the pathophysiology of ST.

OBJECTIVETo investigate the role of mitochondrial calcium uniporter in cardioprotection elicited by ischemic postconditioning (Postcond).

METHODSMale Sprague-Dawley rats were used for Langendorff isolated heart perfusion. The hearts subjected to global ischemia for 30 min followed by 120 min of reperfusion. Left ventricular developed pressure (LVDP), maximal rise/fall rate of left ventricular pressure (± dP/dtmax) were measured. The level of lactate dehydrogenase (LDH) in the coronary effluent was measured spectrophotometrically, the content of formazan of myocardium was also measured at the end of reperfusion.

RESULTCompared to I/R group, Postcond had an significant increase in the mechanical function of the left ventricle, with LDH release reduced and the content of formazan increased. Spermine, the opener of mitochondrial calcium uniporter, deteriorated the mechanical function of left ventricle and decreased the formazan content, and increased LDH release. Ruthenium red, the inhibitor of mitochondrial calcium uniporter, increased the mechanical function of the left ventricle, decreased the LDH release, but the content of formazan was not increased.

CONCLUSIONThe inhibition of mitochondrial calcium uniporter is involved in the mechanisms of ischemic postconditioning.

OBJECTIVE To study the isolation and resistance tendency of Acinetobacter calcoaceticus-baumannii to antimicrobial agents from 1998 to 2004 to provide valuable data for infection prevention and therapy. METHODS We reviewed the isolation rates,distribution in clinical specimens and wards,and the resistance rates of(A.calcoaceticus-baumannii)to 14 kinds of antimicrobial agents from 1998 to 2004. RESULTS There was an increasing tendency of isolation rates of A.calcoaceticus-baumannii every year,which was 0.18% in 1998 but 1.48% in 2004.In the seven years,there was the highest isolation rate of 70.58% in specimens from respiratory tract,the next was from the urine(9.42%),and blood(4.63%).Concerning the wards distribution,ICU had the highest rate of 47.28%.In 1998,A.calcoaceticus-baumannii had resistance rates more than 50% only to one kind of antimicrobial agents(aztreonam),but in 2004,it had increased to thirteen kinds(except cefoperazone/sulbactam).About the fourteen kinds of antimicrobial agents we inspected,that were increased in their resistance rate.The highest increasing of resistance rate was ceftazidime from 11.1% in 1998 to 88.9% in 2004,the imipenem was second for 0.0% to 64.8%,and the third was sulfamethoxazole/trimethoprim form 0.0% to 64.0%,while there still was an increasing resistance tendency to them. CONCLUSIONS The clinical isolation rate of A.calcoaceticus-baumannii is increasing,and it has higher resistance rates to many antimicrobial agents as well as an increasing resistance tendency to relatively susceptive antimicrobial agents every year.So physicians should prescribe on the basis of antimicrobial agents susceptibility tests in vitro.

OBJECTIVETo compare clinically therapeutic effects of warming needle moxibustion and simple acupuncture on knee osteoarthritis.

METHODSOne hundred and twenty cases conformed with the diagnostic criteria of knee osteoarthritis with TCM kidney-yang deficiency and cold syndrome were randomly divided into a warming needle moxibustion group and a simple acupuncture group. Guanyuan (CV 4), Qihai (CV 6), Zusanli (ST 36) and others were selected in the two groups. Their therapeutic effects were assessed with joint pain scale, knee osteoarthritis severity index scale and cold syndrome differentiation factors.

RESULTSBoth warming needle moxibustion and simple acupuncture could alleviate pain of knee osteoarthritis, improve dysfunction of the knee joint, reduce symptoms. The clinically basic cured rate and the total effective rate were 32.1% and 96.4% in the warming needle moxibustion group, which were better than 7.4% and 92.6% in the simple acupuncture group.

CONCLUSIONWarming needle moxibustion is an effective therapy for knee osteoarthritis with kidney-yang deficiency and cold type.

OBJECTIVETo observe the toxicity of Pulsatilla chinensis (Bunge) Regel saponins (PRS) against Oncomelania hupensis (O. hupensis).

METHODSO. hupensis snails were exposed to 40% and 80% of 24 h LC50 of PRS for 24 h, and then choline esterase (CHE), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH) activities in cephalopodium and liver of snails were determined. Niclosamide (NIC) was used as the reference molluscicide. Zebra fish lethality test was evaluated to non-target aquatic species of PRS.

RESULTSThe molluscicidal activity of PRS (LC50 at 24 h: 0.48 mg/L) was similar to that of NIC (LC50 at 24 h: 0.16 mg/L). Significant alterations about CHE, ALP, and ALT activities both in the cephalopodium and the liver of snails were observed when O. hupensis was exposed to 40% and 80% LC50 of PRS or NIC for 24 h. PRS and NIC could not affect LDH activity in the cephalopodium and the liver. Lower toxicity to fish of PRS was observed up to the highest concentration tested than NIC.

CONCLUSIONPRS, as compared with the reference molluscicide NIC, is thought to be used for the control of harmful vector snails safely.

Objective: To observe the joint effect of school and family tobacco control on middle school students, and to explore its effectiveness in reducing second-hand smoke exposure in middle school students’ families, as so asto provide a new way of thinking for controlling smoking among middle school sudents. Methods: A questionnaire survey was conducted on the study of 2 125 primary and high school students in four middle schools in the Dongcheng District of Beijing by means of a stratified group sampling method. Personal information of students, tobacco control environment around the family, school and surrounding ares, as well as the knowledge, attitude and behavior of students related to tobacco control was collected. Results: The exposure rate of second-hand smoke in the families of middle and high school students in Dongcheng District of Beijing was 33.41%. Smoking by at least one parent was positively correlated with second-hand smoke exposure in the student’s home (OR=22.88, P<0.05). Among the students who saw the "clear no-smoking label" on campus, the exposure rate (4.92%) when the smoking restriction was set on the home was lower than that of those who did not have a regulation in the home (58.94%) (χ2=452.57, P<0.01). The results of Logistic regression showed that there was a combination of family smoking restrictions and second-hand smoke exposure in middle and high school students who had seen the smoking ban on campus (OR=0.08) and had the school’s tobacco control education (OR=0.08). Conclusion The joint tobacco control measures between school and family can effectively reduce the exposure rate of second-hand smoke in middle school students’ families, which is better than the effect of tobacco control alone.
