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.

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.

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 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.

OBJECTIVETo analyze the genotype and phenotype correlation in the hemoglobin E (HbE) carriers, and to investigate the effect of HbE on hematological parameters.
METHODSThe capillary electrophoresis was used to screen total 14 141 samples and blood cell analysis was further processed to the HbE carrying samples. Gap-PCR and reverse dot blot hybridization method were used for the detection of Chinese common mutation of α and β thalassemia.
RESULTSThere is a statistical difference in hematological phenotype index (HGB, MCV, MCH, HbE, HbA(2)) between samples of HbE heterozygous (53 samples), HbE homozygous (2 samples), HbE composite α thalassemia (α-thal, 7 samples) and HbE composite β thalassemia (β-thal, 8 samples). Among the four groups, HbE heterozygous \[HGB (122.7 ± 19.99) g/L, MCV (78.65 ± 5.03) fl\] and HbE composite α-thal \[HGB (113.6 ± 22.68) g/L, MCV (73.50 ± 7.73) fl\] had slight effect on hematological parameters, but HbE composite β-thal \[HGB (76.4 ± 12.30) g/L\], MCV (59.23 ± 5.28) fl\] had the heaviest effect on hematological parameters.
CONCLUSIONCo-existence of HbE heterozygous and other type thalassemias showed variation in their hematological phenotype, so patients should be informed of genetics in prenatal diagnosis.
