Interleukin 33 (IL 33),one member of the IL-1 family,is expressed in many types' tissue and regulation of multiple target cells via its suppression of tumorigenicity 2 (ST2) receptor.Therefore,the crucial roles of the novel cytokine IL-33 in allergic,endocrine diseases,infectious diseases and cancer are becoming characterized.The function of IL-33 in different parasite infection is distinctive in parasitic infections,due to the difference in pathogenic mechanism and in the time course of IL-33 expression.

Objective To assess the optimal visiualization capacity of brachial plexus with three-dimensional nerve-sheath signal increased with inked rest-tissue rapid acquisition of relaxation imaging (3D SHINKEI), exploring the feasibility of preliminary diagnostic value on brachial plexus diseases. Methods MRI scans were performed on 24 healthy volunteers with no history of brachial plexus injury, and 46 patients whose outcomes of lesions had been verified as post-ganglionic brachial plexus injuries by surgery or clinical follows-up . The scan series consist 3D SHINKEI, STIR in the coronal plane as well as DW-MRN in the axial plane using a 3.0 T MR system. The source and post-processed images of 3D SHINKEI and DW-MRN were scored according to the optimal visibility on brachial plexus, in the meanwhile, contrast-to-noise ratio of the original images in the 3D SHINKEI and STIR sequences were calculated separately. Two radiologists blindly compared the detection rate of positive brachial plexus injuries between 3D SHINKEI and STIR in 46 patients. And then analyze the outcomes by means of Kappa test, Mann-Whitney test , independent sample t test, and Chi-square test. Results Post-ganglionic brachial plexus showed high intensity in the 3D SHINKEI sequence. In the 24 healthy volunteers, the scores by the two radiologists were 3.6 ± 0.6, 3.5 ± 0.6, 3.0 ± 0.2, 2.9 ± 0.1, respectively. There was statistical difference between the two sequences (Z=2.667,P=0.008,P<0.05). And the Kappa was 0.8 and 0.6 with favorable consistency. The CNR of 3D SHINKEI and STIR were 0.61 ± 0.07, 0.42 ± 0.03 (t=12.78, P=0.001, P<0.05). The positive detection rates of post-ganglionic brachial plexus injuries on 3D SKINKEI and STIR were, 78.3%, 52.2%(χ2=9.421, P<0.05). Conclusions 3D SHINKEI sequence demonstrates robust visibility consistently and can clearly display the structures and signals of post-ganglionic abnormality, compared with DW-MRN and STIR. This technique can be helpful to provide more complementary information to further confirm the diagnosis of brachial plexus injuries.

Human leukemia is closely associated with various genetic alterations such as chromosomal translocations and gene mutations. The use of retroviral transduction/bone marrow transplantation mouse model harboring these genetic abnormalities has been critical in understanding the molecular pathogenesis of leukemia and exploring new therapeutic target. Additional genetic events are verified to cooperate with fusion genes resulting from chromosomal translocations in acute myeloid leukemia (AML) to develop a leukemic phenotype in mice, such as C-KIT N822K with AML1-ETO, FLT3-ITD with PML-RARα, Meis1 with NUP98-HOX, and Cdx4 with MLL-AF9. Mouse model shows that BCR/ABL fusion gene induces chronic myeloid leukemia (CML), and suggests that GATA-2 L359V and high expression of Hes1 are key molecules in acute myeloid transformation of CML. Furthermore, combination therapy with Imatinib and arsenic sulfide for CML mice exerts more profound therapeutic effects than either drug as a single agent. This review focuses the recent progress and application of retroviral-mediated mouse models of myeloid leukemia, and discusses some factors influencing the mouse model establishment, including retroviral construction, retrovirus titer and hematopoietic microenvironment.

Objective To propose a new diagnostic criterion for rosacea based on the analysis of clinical features of rosacea in a large sample.Methods A total of 1 090 Chinese outpatients with rosacea were enrolled from Department of Dermatology of Xiangya Hospital,and their demographic data,clinical manifestations and subjective symptoms were collected.According to results of descriptive analysis,clinical features of rosacea were summarized,and a new diagnostic criterion for rosacea was set up.Then,the sensitivity and specificity of the new diagnostic criterion were verified among 1 200 outpatients clinically characterized by facial erythema.Results Of 1 090 patients with rosacea,131 (12.0％) were male and 959(88.0％) were female,and the average age was 33.5 ± 11.1 years (range,10-66).Among the 1 090 patients,715 (65.6％) had initial lesions on the cheek,of whom,712 (99.6％) had intermittent flushing as the initial symptom,and 689 (96％) had sensitive skin symptoms such as dryness,burning and itching sensations;208 (19.1％) had initial lesions on the perioral region,of whom,204 (98.1％) had persistent erythema as the initial symptom;167 (15.3％) had initial lesions on the nose,of whom,163 (97.6％) had persistent erythema as the initial symptom;in addition,311 (28.5％) had lesions on the ocular region,and only 24 (2.2％) had lesions outside the face on the neck and retroauricular region.Based on these clinical features,a new diagnostic criterion for rosacea was proposed,including 1 major condition (intermittent flushing or persistent erythema on the cheek,perioral region or nose) and 5 minor conditions (1.sensitive skin symptoms such as burning,tingling,drying or itching sensations;2.telangiectasia;3.papules or pustules;4.hypertrophy;5.ocular symptoms).If with the major condition and at least one minor condition were met,patients could be diagnosed with rosacea.After verification among 1 200 patients with facial dermatitis clinically characterized by facial erythema,the new criterion was proved to have a sensitivity of 99.3％ and a specificity of 95.8％.Conclusion A new diagnostic criterion for rosacea with high sensitivity and specificity is proposed,which is worthy of clinical application.

OBJECTIVETo investigate the influence of therapeutic bloodletting at Jing-well points and hypothermia on acute cerebral edema after traumatic brain injury (TBI) in rats.

METHODSSeventy-five SD rats were randomly divided into sham-operation group (Sham), TBI group (TBI), bloodletting group (BL), mild-induced hypothermia group (MIH), and bloodletting plus MIH group (BL + MIH) (n = 15). The model of TBI was established by electric controlled cortical impactor (eCCI). The rats of BL group were bloodletting at Jing-well points immediately after injury, twice daily. While the MIH group was settled on a hypothermia blanket promptly after TBI for 6 hours, so that the temperature dropped to 32 degrees. Each of measurement was performed after 48 hours. Magnetic resonance imaging (MRI) was used to evaluate the dynamic impairment of cerebral edema after TBI (n = 3). In addition, mNSS score, measurements of wet and dry brain weight, and Evans Blue assay were performed to investigate the neurologic deficit, cerebral water content (n = 8), and blood-brain barrier permeability (BBB), (n = 4), respectively.

RESULTSMRI analysis showed that the cerebral edema, hematoma and midline shifting of rats in TBI group was more serious than other treatment group. Meanwhile compared with TBI group, the mNSS scores of every treatment group were meaningfully lower (all P < 0.05). Furthermore, treatment with BL+ MIH group was superior to the separated BL and MIH group (all P < 0.01). In addition, brain water content of each intervention group reduced to varying degrees (all P < 0.05), especially that of MIH group and BL + MIH group (P <0.01). BBB permeability of each treatment group was also significantly improved (all P < 0.01), and the improvement in MIH group and BL + MIH group was much better than the BL alone group (P < 0.05, P < 0.01).

CONCLUSIONOur major finding is that bloodletting at Jing-well points and MIH can reduce cerebral edema and BBB dysfunction and exert neuroprotective effects after TBI. The results suggest that the combination of BL and MIH is more effective than other treatment being used alone.

Objective: To investigate anxiety life interference among primary and middle school students in Henan Province and its influencing factors, and to provide scientific basis for health education in primary and secondary school students. Methods: By using cluster sampling method, 3 573 primary school students and 2 748 secondary school students in Henan Province were investigated with Child Anxiety Life Interference Scale(CALIS), Resilience Scale for Chinese Adolescents(RSCA), Perceived Social Support Scale(PSSS), Self-Esteem Scale(SES), General Self-efficacy Scale(GSES). Results: There were significant differences in anxiety life disturbance in primary and middle school students by gender(t=2.07, P=0.04), school level(t=-2.29, P=0.02), degree of anxiety(F=119.93, P<0.01), educational level of fathers (F=13.38, P<0.01) and educational level of mothers(F=9.65, P<0.01). The degree of life disturbance caused by anxiety was negatively correlated with mental resilience, social support and self-efficacy(r=-0.25, -0.09, -0.12, P<0.01), and was positively related to self-esteem(r=0.23). Mental resilience (β=-0.21) significantly negatively predicted anxiety interference with life, while self-esteem (β=0.13) and social support (β=0.06) significantly positively predicted anxiety interference with life. Conclusion The life of primary and middle school students is seriously disturbed by anxiety, and mental resilience is the primary psychosocial factor that affects the level of anxiety life interference among primary and middle school students.

Objective To construct the eukaryotic expression plasmid containing glyceraldehydes-3-phosphate dehydrogenase (GAPDH) and cysteine protease inhibitor ( CPI ) gene from periodic Brugia malayi (Bm) and to lay foundation for studying multivalent vaccines. Methods Total RNA was extracted from periodic Bin. The BmGAPDH and BmCPI genes were amplified by RT-PCR. The PCR product was cloned and then subeloned into eukaryotic recombinant plasmid vector pcDNA3.1 (+). pcDNA3.1 (+)/BmGAPDH/BmCPI was constructed. The recombinant plasmids were screened and identified by digestion with restriction enzyme and PCR amplification, and were transformed into HeLa cell subsequently. The transient expression of BmGAPDH and BmCPI were examined by RT-PCR. The expressed protein was identified by sodium dodeeylsulphate-polyacrylamide gel electrophoresis(SDS-PAGE). Results Two specific bands of around 877 bp of BmGAPDH and 621 bp of BmCPI were amplified, consistent with the expected value. The same bands were obtained by double restriction enzyme digestion of recombinant plasmids or PCR using recombinant plasmid as template. BmGAPDH and BmCPI mRNA were highly expressed in transfeeted HeLa cell. The relative molecular mass (Mr) of the recombinant protein was about 54 × 103. Conclusion The recombinant eukaryotic expression plasmid pcDNA3.1 (+)/BmGAPDH/BmCPI has been constructed successfully and the protein is expressed correctly in mammalian cell.

Abnormalities of chromosome 11 involving mixed lineage leukemia (MLL) on 11q23 are often seen in acute myeloid leukemia (AML)-M5 or AML-M4. The fusion gene of MLL-PTD and MLL plays a critical role in the pathogenesis of these AML. However, rare chromosome abnormalities have been identified in this type of leukemia. To explore whether there were other MLL gene mutations at M4 and M5, in this study all of the MLL exons were sequenced at cDNA level. 25 patients with de novo AML-M4 or M5 with normal karyotypes excluding M4eo and MLL fusion gene or MLL-PTD were selected, the amplification and direct sequencing analysis of full length MLL gene exons were carried out, then the mutations found were verified at genomic DNA level. Furthermore, the point mutations were tested in normal samples and a larger group of AML patients using the platform of Mass Array. The results showed that high-frequency deletion/insertion and point mutations in RD, PHD, TAD and SET domains of MLL were found, while these alterations in normal samples and other subtypes of AML samples were also verified, and without significant difference (P > 0.05). It is concluded that a variety of deletions/insertions in MLL mRNA and point mutations are respectively alternative splicing of MLL gene at transcriptional level and single nucleotide polymorphism. These alternations together constituted genetic polymorphisms of MLL. Although these variations may not play a direct role in the molecular pathogenesis of AML-M4 or M5, their correlations to clinical treatment and prognosis need to be further explored.
