Objective :To explore the behavior characters of children diagnosed as ODD with ADHD symptoms. Methods: The diagnosis of ODD was made according to the ICD-10 criteria . 40 Children having ODD with ADHD symptoms (combined group ) and 22 Children having ODD but without ADHD symptoms (ODD group) were collected from outclinics. The parents of all subjects completed Achenbach Child Behavior Checklist (CBCL) and a family information list. Results: The onset and help-seeking age of the combined group were younger than that of ODD group. They had more disobey, attacking, and extroversive behaviors. Their fathers were more agitative. Parents of the combined group used more beating and scolding in parenting. Conclusion: ODD children with ADHD symptoms had more behavior problems and incur worse parenting style. Their family need more help in early age.

Objective To explore the clinical effect of sustained low-efficient dialysis (SLED) combined with hemoperfusion(HP)in sepsis patients,and its protection for the kidney.Methods Sixty two patients of sepsis with acute kidney injury(AKI) were randomly divided into two groups.Based on routine treatment,control group (n =31) was treated with HP alone for 2h per day,and combined group (n =31) was treated with HP and SLED at the first 2h,and SLED for the next 10-12h.All the patients were treated for 3 days.The inflammation factors and index of renal function were detected before and after treatment,and change of haemodynamics were observed and analyzed.Results After treatment for 12,24,48h,the TNF-α,IL-6,IL-10 and Scr,BNP in both groups were all improved,while the inflammation factors in combined groups at 48h after treatment were significantly lower than those in control group,and levels of Scr and BNP at 12,24,48h after treatment were all lower than those in control group (P ＜ 0.05).There were no significant differences on the levels of CVP,MAP at 12,24,48h after treatment in combined groups (P ＞ 0.05),while these indicators were all higher than those in control group (P ＜ 0.05).Conclusion HP combined with SLED in treating sepsis with AKI can effectively remove inflammatory mediators,promote kidney function recovery and stability of hemodynamic.

Objective:To explore the changes in the diffusion tensor imaging (DTI) parameters of the pontocerebellar tract 3 months and one year after ischemic stroke and analyze the data′s potential for predicting long-term motor outcomes.Methods:Thirty patients with middle cerebral artery infarction were prospectively studied using DTI within 3 months and 1 year after the onset. A region of interest-based analysis was performed for the fractional anisotropy (FA) of the middle cerebellar peduncles (MCP) in the pontocerebellar fibers (PCF). Neurological functioning was evaluated using the National Institutes of Health Stroke Scale and the degree of paresis was assessed at the same time using paresis grading. At one year after the onset, balance function, functional prognosis and self-care ability were evaluated using the Brunel Balance Scale, the modified Rankine Scale and the Functional Independence Scale respectively.Results:The average FA on the healthy side 3 months and 1 year after onset was significantly less than on the affected side at each time point. The ratio of the FA of the affected side to that of the unaffected side (rFA) in the PCF correlated significantly with the average paresis scores of the lower and upper extremity and the total paresis score at each time point. Moreover, the rFA of the PCF was significantly correlated with the average functional independence score, the prognosis for the upper and lower extremities as well as motor functioning. The area ratio under the ROC curve of the PCF for predicting lower extremity motor outcome was 0.84, and the optimal threshold was 0.92 (sensitivity 71.4%, specificity 73.9%). The area ratio under the ROC curve was not a significant predictor of upper extremity motor outcome.Conclusion:The DTI parameter rFA of the PCF in patients with subacute middle cerebral artery infarction can help to predict the long-term recovery of motor ability. It can serve as an important reference index for predicting the long-term motor ability of the lower limbs.

Objective: To explore the effectiveness of Balint group on compassion fatigue among oncology nurses. Methods: From January to December 2016, 35 oncology nurses from one general hospital were enrolled. 18 cases were allocated in the observation group and 17 cases in the control group by computer randomization. Nurses in the observation group were received a total of 8 times Balint Group activities, with 2 times a month and 1.5 hours each time, which is aiming to discuss difficult cases encountered in the clinic to help nurses have a deeper experience and a better understanding of the emotions and behaviors, fantasies and needs between nurse-patient interaction. Nurses in the control group without intervention. All the Participants were requested to complete the survey of the Professional Quality of Life (ProQOL) , the Jefferson Scale of Empathy-Health Professionals (JSE-HP) , and the General Health Questionnaire (GHQ) at pre and post intervention. Results: Before intervention, two group of nurses in age, working years, marriage, and education were not statistically significant (P>0.05). There was no difference in the scores of empathy, compassion satisfaction, secondary traumatic stress, and General health (P>0.05). After intervention, the scores of JSE-HP and its three dimensions of perspective taking, emotional care, and trans-positional consideration in the observation group had significantly higher than the control group (P<0.05). The level of compassion satisfaction in the observation group was higher, and the general health status was lower (P<0.05). There was no statistically difference in the level of burnout and secondary traumatic stress between two groups (P>0.05) . Conclusion Balint group has a positive role in promoting nurses’empathetic skills, compassion satisfaction and mental health.

BACKGROUND/AIMS: The current study aims to investigate the protective effects of Bifidobacterium infantis on the abnormal immune response to inflammatory bowel disease (IBD) in dextran sodium sulfate (DSS)-induced colitis. METHODS: Eight-week-old BALB/c mice were separated into five groups at random (control, DSS, DSS+B9 [B. infantis 1×10⁹ CFU], DSS+B8 [B. infantis 1×10⁸ CFU], and DSS+B7 [B. infantis 1×10⁷ CFU]). Colitis was induced by 5% DSS ad libitum for 7 days, at which time we assessed weight, the disease activity index (DAI) score, and the histological damage score. The nuclear transcription factor Foxp3 (a marker of Treg cells), cytokines interleukin-10 (IL-10) and transforming growth factor β1 (TGF-β1), and related proteins (programmed cell death ligand 1 [PD-L1] and programmed cell death 1 [PD-1]) were detected by an immunohistochemical method and Western blot. RESULTS: B. infantis increased weight, decreased DAI scores and histological damage scores, increased the protein expression of Foxp3 (p<0.05) and cytokines IL-10 and TGF-β1 in mouse colon tissue (p<0.05), and increased the expression of PD-L1 in the treatment groups relative to that in the DSS group (p<0.05). The effect of B. infantis on Foxp3 and PD-L1 was dose dependent in the treatment groups (p<0.05). PD-L1 was positively correlated with Foxp3, IL-10, and TGF-β1. CONCLUSIONS: In a mouse model of IBD, B. infantis can alleviate intestinal epithelial injury and maintain intestinal immune tolerance and thus may have potential therapeutic value for the treatment of immune damage in IBD.

Due to the decline of motor ability and the impact of the diseases, abnormalities in gait is common in the elderly population, which will raise the risk of fall and cause serious injury. This study focuses on the analysis of the gait kinematics parameters of normal adults' gait, aiming to investigate the characteristics of gait parameters in different age groups and to explore the role of gait parameters in motor function assessment and clinical diagnosis. Based on the gait data gained by electronic walkway, the relationship among the toe out angles and their correlation with age and gender etc. were quantitatively analyzed. The results show that most normal subjects walk with positive toe out angles, and the angles increase with age. Such changes are slow in the young and middle age groups. However, the elevations of the left out toe angle and the angles between the feet are statistically significant after entering elder age ( >60 years). The results also suggest that the angle between the feet is a kind of practical gait parameter for varying applications. This study concludes that feet angle analysis is potential to provide a convenient and quantitative tool for the assessment of lower limb motor ability and the diagnosis of knee joint diseases.

OBJECTIVEThe authors sought to investigate the clinical features and characteristics of genetic mutation in patients with aspartylglucosaminuria.

METHODClinical data of two pediatric siblings in a family were analyzed retrospectively and relative literature was reviewed in order to study the clinical features, imaging and enzymatic characteristics and genetic mutations.

RESULTCase 1, the proband, male, he was hospitalized at 20 months of age because of fever and hepatosplenomegaly for nine days. This child was of moderate nutritional status and normal development. Blood tests showed hemoglobin 78.0 g/L, RBC3.18 × 10¹²/L, WBC 4.06 × 10⁹/L, neutrophils 0.236, lymphocytes 0.631, platelets 34 × 10⁹/L, C-reactive protein 17 mg/L. Blood biochemistry showed alanine aminotransferase 67.1 U/L, aspartate aminotransferase 74.1 U/L, serum albumin 32.8 g/L, direct bilirubin 10.5 µmol/L, lactate dehydrogenase 301.7 U/L. Bone marrow cytology showed reactive morphological changes in bone marrow cells. Atypical lymphocytes could be seen in both peripheral blood and bone marrow smears. Cranial MRI showed poor myelination. Aspartylglucosaminidase activity in peripheral leucocytes of the proband 5.7 nmol/(g × min) vs. normal control>26.6 nmol/(g × min). On his AGA gene and that of his parents, a heterozygous mutation site located in exon 3, c.392C>T (p.S131L), was identified as a novel mutation inherited from his father. The mutation from his mother has not been detected. The proband was not responsive to the anti-infectious medication, nutritional intervention and symptomatic treatment.He died one month after diagnosis.His elder brother, Case 2, showed fever, recurrent respiratory tract infection and progressive psychomotor regression with hepatosplenomegaly from the age of four years. Cranial MRI revealed extensive symmetrical leukodystrophy in bilateral cerebra, cerebellum and brainstem.He died at the age of six years.Related literature was summarized, and no Chinese AGU cases had been reported; 221 foreign cases were collected. The clinical and imaging characteristics were summarized. Delay in language development was one of the clinical symptoms that the majority of parents of AGU children first noted.

CONCLUSIONPatients with aspartylglucosaminuria lack of specific symptoms.For children with unexplained delayed speech and progressive mental retardation, the possibility of AGU should be considered, and efforts be made for enzymatic and genetic diagnosis. c.392C> T (p.S131L) was identified as a novel mutation of AGA gene.
