Objective To investigate the levels of interleukin-15(IL-15) in children with acute leukemia and contribute to understand their function on acute leukemia about the process.Methods Every group of acute lymphocytic leukemia(ALL),acute nonlymphocytic leukemia(ANLL) or non-leukemia group had 20 children who did not receive any treatment. Peripheral blood of every group and 20 other healthy children were aspirated .The levels of IL-15 in serum was analyzed by enzyme linked immunosorbent assay (ELISA).Results The levels of IL-15 in ALL group,ANLL group, non-leukemia group and healthy children were (34.37?2.8) ng/L, (29.61?3.2 )ng/L, (117.54?3.9) ng/L, (122.23?4.2) ng/L. Compared with the levels of the healthy group or the non-leukemia group, the difference of ALL or ANLL was signicant in statistics(q=3.95,4.03 Pa0.05).Conclusion Detection of serum IL-15 levels may have clinical significance in judging the anti-tumor immune condition in children with leukemia.

Fourteen psychrotrophic bacteria were isolated from swamp soil collected in Ruoergai plateau wetland,and their generation time and degrading ability of livestock wastewater CODcr was determined.The results showed that the generation time was within 4.9 h to 11.6 h.Based on the generation time,9 psychro-trophic strains(NLJ1,NLJ6,NLJ7,NLJ9,NLJ10,NLJ11,NLJ12,NLJ13 and NLJ14),whose generation time was within 4.9 h to 5.6 h,were chosen to treat livestock wastewater.The results suggested that these 9 strains had different CODcr disposal ability when treating livestock wastewater singly at 6?C for 6 h,and strains NLJ6,NLJ7,NLJ9,NLJ10,NLJ11 and NLJ13 had good ability to degrade livestock wastewater,the CODcr degrading rate was about 60%~70%,hence,they were used as high efficient strains;However,the CODcr degrading rate of the other strains was less than 50%.After inoculating mixture culture of these six strains into the distilled livestock wastewater,after 6 h's treating,the CODcr degrading rate reached to 85.42%.Furthermore,activated sludge collected from Yaan,Dujiangyan and Chengdu were inoculated by the mixture culture of those six strains,and used to treat livestock wastewater for 6 h.The results showed that the average CODcr degrading rate was 81.67%,76.32% and 70.56%,respectively;Variance analysis showed that there was no significant differentiation between each treatment,which revealed that those six psychrotrophic strains had good adaptability to different source of activated sludge.

OBJECTIVETo observe changes in activity and proliferation of cultured Schwann cells under the high glucose condition and effect of allyl glycoside extracted from Herba Rhodiolae (AG) on these changes for exploring the possible mechanism of diabetic peripheral nerve injury and the pharmacologic action of AG on them.

METHODSAdopting refined Brokes method, Schwann cells were isolated from the sciatic nerve tissue of newborn Wistar rats and purified. Their activity and proliferative capability were determined using XTT method and 3H-TdR incorporative method respectively.

RESULTSHigh glucose showed marked inhibitory effect on both activity and proliferative capability of Schwann cells, and the inhibition could be markedly improved by AG.

CONCLUSIONDiabetic peripheral nerve injury is possibly related to inhibitory effect of high glucose on activity and proliferative capability of Schwann cells. Effect of AG in improving these inhibitory changes provides the experiment basis for clinical use of traditional Chinese medicine, Herba Rhodiolae.

OJBECTIVETo investigate the predictive value of the qualitative assessment of general movements (GMs) for adverse outcomes at 24 months of age in full-term infants with asphyxia.

METHODSA total of 114 full-term asphyxiated infants, who were admitted to the neonatal intensive care unit between 2009 and 2012 and took part in follow-ups after discharge were included in the study. All of them received the qualitative assessment of GMs within 3 months after birth. The development quotient was determined with the Bayley Scales of Infant Development at 24 months of age.

RESULTSThe results of the qualitative assessment of GMs within 3 months after birth showed that among 114 infants, 20 (17.5%) had poor repertoire movements and 7 (6.1%) had cramped-synchronized movements during the writhing movements period; 8 infants (7.0%) had the absence of fidgety movements during the fidgety movements period. The results of development quotient at 24 months of age showed that 7 infants (6.1%) had adverse developmental outcomes: 6 cases of cerebral palsy and mental retardation and 1 case of mental retardation. There was a poor consistency between poor repertoire movements during the writhing movements period and the developmental outcomes at 24 months of age (Kappa=-0.019; P>0.05). There was a high consistency between cramped-synchronized movements during the writhing movements period and the developmental outcomes at 24 months of age (Kappa=0.848; P<0.05), and the results of predictive values of cramped-synchronized movements were shown as follows: predictive validity 98.2%, sensitivity 85.7%, specificity 99.1%, positive predictive value 85.7%, and negative predictive value 99.1%. There was a high consistency between the absence of fidgety movements during the fidgety movements period and the developmental outcomes at 24 months of age (Kappa=0.786; P<0.05), and its predictive values were expressed as follows: predictive validity 97.4%, sensitivity 85.7%, specificity 98.1%, positive predictive value 75.0%, and negative predictive value 99.1%.

CONCLUSIONSCramped-synchronized movements and absence of fidgety movements can predict adverse developmental outcomes at 24 months of age in full-term infants with asphyxia.

Objective To explore the physical and mental health status on the ‘left behind ’ students in Anhui province and the related influential factors.Methods Stratified cluster sampling method was used to investigate the 682 out of 3421 students from 7 middle schools in both south and north Anhui province,using multidimensional sub-health questionnaire of adolescents (MSQA) and mental health test (MHT),for assessment of the general condition,physical and mental health status.Results 14.22％ of the ‘left behind’ students were in sub-health condition compared to 11.28％ among the normal students,and the mental sub-health status represented 13.64％ for the former and 10.84％ for the latter.In addition,the ‘left behind’ students appeared less content with their life than those of staying with their parents (P＜0.05).MHT scores in the subjects were positively correlated with the scores on MSQA and showed significant difference (P＜0.01).Results from the multiple linear regression analysis showed that the mental health condition among the left behind students was in linear regression relationship with the decreased physical activity (β =1.456,P=0.001 ),emotional problems (β =1.096,P=0.000 ) and problems of social adaptation (β=1.011,P=0.006).The status of physical sub-health in the Anhui province showed that there was no significant difference in each of the study group (P＞0.05).Conclusion Decreased physical activity and emotion aporia as well as difficult social adaptation were major factors leading to degenerated mental health levels in the‘left-behind’ adolescents.The findings suggested that the mental health status could be improved inthis population through better management on their body-health condition.

Objective By exploring the mental health situation of the unattended adolescents in Anhui province. This study aimed at investigating the status of mental health and related influential factors to provide evidence for effective strategies and intervention in physical and mental health improvement of this population. Methods By using stratified cluster sampling method, we conducted an investigation on 3421 subjects,in which 682 were unattended adolescents,from 7 middle schools in both south and north parts of Anhui province. MHT was used to assess the general condition and status of mental health in the adolescents. Results In the population aged 10 to 18 in Anhui province,19.94% of them were unattended adolescents and were found with poor mental health and more prone to loneliness, sensitive and stronger fear as compared with those with parents around, which showed statistical difference (P＜0.05). As for the mental health status of unattended adolescents in different family types, the subjects seemed worse in the north than in the south Anhui regarding the total scores of MHT, self-accusation, physical symptoms and phobic anxiety disorder (P＜0.05). Girl students were also inferior to boys concerning the total scores of MHT, learning anxiety, interpersonal anxiety, self-accusation, sensitivity, physical symptoms and impulsive behavior (P＜0.05). The students in Grade 7 scored lower than those of the upperclassmen on MHT (P＜0.05), and the subjects from township were superior to those of rural areas regarding interpersonal anxiety and loneliness (P＜0.05). Children with siblings appeared worse than their counterparts on the total scores of MHT, including the items of interpersonal anxiety, learning anxiety, self-accusation, sensitivity,physical symptoms, strong fear and impulsive behavior (P＜0.05). Conclusion Generally, the mental health status of unattended adolescents in Anhui province appeared poorer than their counterparts, and relatively worse psychological status was seen in girls, high school students,children with siblings and subjects living in north Anhui or rural areas.

Objective To investigate the distribution and antimicrobial resistance of Pseudomonas aeruginosa (P.aeruginosa) from intensive care units(ICUs) and general wards of a hospital,and provide scientific basis for rational use of antimicrobial agents in clinic.Methods Identification and antimicrobial susceptibility testing of clinically isolated bacteria in this hospital in 2016 were performed by VITEK 2 Compact automatic microbial analysis system,difference in antimicrobial resistance of P.aeruginosa between ICUs and general wards was compared.Results The tested specimens were mainly sputum in both ICUs and general wards,accounting for 78.7％ and 66.5％ respectively.There was no significant difference in the isolation rate of P.aeruginosa between ICUs and general wards (11.7％ vs 11.0％,P＞0.05).P.aeruginosa isolated from ICUs had the highest resistance rate to aztreonam (73.8％),resistance rates to piperacillin/tazobactam,cefoperazone/sulbactam,ceftazidime,imipenem,and meropenem were all up to more than 50％;P.aeruginosa detected in general wards had the highest resistance rate to aztreonam(59.6 ％),followed by piperacillin/tazobactam and imipenem,accounting for 48.0 ％ and 44.3 ％ respectively;resistance rates of P.aeruginosa isolated from ICUs to 12 kinds of antimicrobial agents were all higher thanthose of general wards(P＜0.05).Conclusion Resistance rate of P.aeruginosa from ICUs is higher than that in general wards,which should be paid attention,antimicrobial agents should be selected for clinical treatment of infection according to the results of antimicrobial susceptibility testing result.
