Academic Journal of Second Military Medical University 1981;0(03):-
Objective:To study the therapeutic effect of 2 artificially synthesized fusion peptides on scalded mice. Methods: Two new fusion peptides, M-T508 and M-T?1, were synthesized based on amino acid sequences selected according to the characteristics of scald (including 3 stages: inflammation, infection and repair by cell proliferation). The 2 peptides were applied for second degree scald burn in mice and the healing of the scald burn was observed. The expression ofⅠcollagen, vascular endothelial growth factor (VEGF), proliferating cell nuclear antigen (PCNA), and cytokeratin (CK) was detected by immunohistochemical staining. Serum TNF-? concentration was determined by ELISA in the animals and the blood vessel permeability was analyzed by Evans blue staining. Results: The healing periods of scald burns in the 2 peptide groups were 1 week earlier than that in the control group. Immunohistochemical results showed that the expression of collagenⅠ, VEGF, PCNA and CK was all positive in the 2 peptide groups 10 days after scald and negative in the control group. Examination of blood vessel permeability and serum TNF-? concentration in the M-T?1 and M-T508 groups showed that the 2 fusion peptides had anti-inflammation and anti-infiltration effects in scalded mouse. Conclusion: The synthesized fusion peptide M-T?1 and M-T508 can promote the healing of scald burns in mice.

Objective To investigate cognitive function and behavior characteristics in the childhood onset schizo?phrenia patients with or without obsessive-compulsive symptoms. Methods One hundred forty-nine schizophrenia chil?dren were recruited and 72 healthy children served as children control group. According to the Schedule for Affective Dis?orders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL), the patients were fur?ther divided into two groups, the children with obsessive-compulsive disorder group (70 cases) and the children without obsessive-compulsive disorder group (79 cases). All the children were retrospectively surveyed and the Achenbach’s Child Behavior Check-list (CBCL) was used to assess their social competence and behavioral characteristics at the age from 6-year-old to 10-year-old. The cognitive function was estimated with WISC, STROOP color and word test, trail making test, visal spatial memory test and maze test. Results Compare to the control group, the CBCL factor scores of behavior problems were higher (P<0.01), social ability factor scores were lower (P<0.05) and all factor scores in the cog?nitive function tests were lower (P<0.05) in the two patients groups. Compare to the patients without obsessive-compul?sive symptoms, the CBCL factor scores of the school situation (P<0.01), splitting force (P<0.01), and physical complaints (P<0.01) were significantly higher and the scores were significantly lower in the test of common sense (P<0.01), wood (P<0.01), STROOP (P<0.01) and BVMT-R (P<0.01) in those with obsessive-compulsive symptoms. Correlation analysis showed that social competence total scores were positively correlated with similarity in the patients with obsessive-com?pulsive symptoms (r=0.31, P<0.01);while behavior problems total scores were negatively correlated with wood (r=-0.31, P<0.01) and patchwork (r=-0.32, P<0.01) in the patients without obsessive-compulsive symptoms. Conclusion The schizophrenia children with obsessive-compulsive symptoms have more behavioral problems in pre-symptom period and their cognitive dysfunction are more severe following onset of the disease. Cognitive function is related to behavioral prob?lems and social competence in the schizophrenia children with or without obsessive-compulsive symptoms .

To establish a new method for simultaneously determining the content of five gingerol compounds in different processing degrees of ginger charcoal and PCA principal component analysis was conducted for analysis. Samples were analyzed on Ultimate TM XB-C18 column (4.6 mm x 250 mm, 5 μm) , with acetonitrile (A) -0.1% phosphoric acid solution (B) as mobile phase for gradient elution. Detection wavelength was set at 280 nm. The flow rate was 0.6 mL x min(-1) and the column temperature was 30 degrees C. The five compounds were separated well and showed good linearity (r ≥ 0.999 7) within the concentration ranges tested. The average value for recoveries was between 98.86% - 101.5% (RSD 1.4% - 2.9%). The contents of five compounds showed difference among different processing degrees of ginger charcoal. Zingiberone had the highest content in the standard carbon, and the content of gingerol was decreased as the deepening of processing degree. Different processing degrees of ginger charcoal were classified into three groups with PCA, and provided scientific basis for establishing the quality standards of ginger charcoal.

Objective To assess the value of multisection spiral CT perfusion in evaluating severity of acute pancreatitis (AP). Methods Eighty two AP patients, who were admitted to the hospital between August 2006 and January 2008, were enrolled. Multisection dynamic CT (MSCT) perfusion was performed on all patients 48-72 hrs after admission by using a multisection CT scanner (Siemens somatom sensation 64), and 30 healthy subjects were served as controls. The data were processed on a siemens workstation using PCT software package. The parameters including blood folw (BF), blood volume (BV), peak time (TTP) and surface permeability (PS) were measured and compared. Results The values of BF, BV, TTP and PS in AP patients were (110.57±60.04) ml·100 ml-1·min-1, (156.68±65.11) ml/L, (146.58±29.46) 0.1 s, (110.73±62.66) 0.5 ml·100 ml-1·min-1, respectively. The decreased BF and BV were found in AP patients compared with controls (P<0.05). However, there was no significant difference in TTP and PS between two groups (P>0.05). Conclusions The decreased perfusion in AP patients was associated with the severity of the disease. The parameters of BF and BV can be used to predicte the severity of AP.
