OBJECTIVE: Discussion of expression and its significance of CD44 in SP cells of nasopnaryngeal carcinoma. METHOD: Flow cytometry was used to sort cultured CNE-2 cells of nasopharyngeal carcinoma for obtaining CD44-SP and CD44+SP cells. Biological differences of CNE-2, CNE-2 SP, CNE-2 NSP, CNE-2 CD44+SP and CNE-2 CD44-SP cells were statistically analyzed by experiments such as cell migration experiments, plate clone formation assay, cell cycle analysis and sensitivity tests to chemotherapeutics. RESULT: Two point 3 perent of SP cells were extracted from CNE-2 cells of nasopharyngeal carcinoma, among which 36.5% was CD44+SP cells. Abilities of proliferation, cell migration and plate clone of CD44+SP cells were significantly higher than other cells (P < 0.01), and its tolerance to chemotherapeutics was significantly higher too (P < 0.01). CONCLUSION The proportion of SP cells in nasopharyngeal carcinoma cells was small, but SP cells had strong activeness in the aspect of cell proliferation with a "seed" characteristic of tumor cells. As CD44+SP cells played an important role in proliferation and chemotherapy resistance of nasopharyngeal carcinoma, it indicated that CD44 can be one of the surface markers of SP cells of nasopharyngeal carcinoma.

Objective To investigate the antibiotic susceptibilities and the profiles of virulence genes of clinically isolated Salmonella enterica serovars Schwarzengrund ( S. Schwarzengrund) strains for bet-ter understanding the epidemiological trend of this type of non-typhoidal Salomonella and to provide guide-lines for the prevention and treatment of S. Schwarzengrund infection. Methods Stool samples and clinical data of patients with acute diarrhea who received treatment in the Second Hospital of Tianjin Medical Univer-sity during May, 2014 to October, 2014 were collected for this study. Enrichment culture and biochemical identification were used to isolate and identify the S. Schwarzengrund strains. The isolated strains were fur-ther analyzed with serotyping analysis, drug susceptibility test, pulsed field gel electrophoresis ( PFGE) and multiple locus sequence typing ( MLST ) . The representative genes carried by Salmonella pathogenicity islands (SPI) 1-5, SPI regulators and virulence plasmids were amplified by PCR. The coding genes of CdtB-islet, which were cdtB, pltA and pltB were amplified and sequenced. Results In total, 16 (14. 8%) out of 108 non-typhoidal Salmonella strains were identified as S. Schwarzengrund strains and all of them were sus-ceptible to 11 kinds of antibiotics such as fluoroquinolone, ampicillin, ceftriaxone and trimethoprim-sulfame-thoxazole. PFGE categorized the 16 S. Schwarzengrund strains into 3 clusters including A clone ( 14 strains), B clone (1 strain) and C clone (1 strain). The strains that isolated from 8 patients who ate the same food belonged to one cluster ( A clone ) , suggesting that it was an outbreak of infection. The 16 S. Schwarzengrund strains showed identical MLST type, which was ST241. The representative genes carried by SPI1-5 ( invA, sitC, hilA, sseL, sifA, mgtC, siiE and sopB) , the regulatory gene ( phoP) and the cytole-thal distending toxin islet (CdtB-islet) coding genes (cdtB, pltA and pltB) were positive, while the genes carried by virulence plasmids (pefA, prot6E and spvB) were negative. The similarities in CdtB-islet coding genes and amino acids sequences between Salmonella typhi and S. Schwarzengrund strains in this study were more than 97% and 98%, respectively. Conclusion In this study, polyclonal S. Schwarzengrund strains of ST241 type were isolated from the patients. They were susceptible to common antibiotics, but carried the virulence genes contained in SPI1-5 and CdtB-islet coding genes and might cause an outbreak of infection. Attention should be paid to the tendency and threat of clinical S. Schwarzengrund infection and continuous surveillance and investigation should be performed.

Objective: To explore the effects and correlation of gross motor intervention on social skills of autistic children. To provide new ideas for rehabilitation intervention of autistic children s social ability. Methods: Recruiting 23 autistic children through WeChat in Nanchang, randomly divided into experimental groups (n=13) and control group (n=10). The experimental group underwent 6 weeks of large muscle exercise intervention, in the control group, Test of Gross Motor Development 3 (TGMD3), Social Responsiveness Scale(SRS) and the Autism Social Skills Scale (ASSS) examined changes in social skills, and analyze the relationship between sports and social ability. Results: TGMD-3 score in the intervention group before intervention was (34.31±9.79) and increased significantly after intervention (59.77±13.92)(t=-15.28, P<0.01). There was no statistical significance before and after experiment in the control group (P>0.05). The scores of SRS and ASSS in the experimental group were (96.77±15.79, 97.31±29.22) before the intervention, and (82.92±15.86, 117.62±24.93) after the intervention, and the differences were statistically significant(t=4.55, -5.61, P<0.01). The difference between the SRS and ASSS scores of the control group before and after experiment was not statistically significant(P>0.05). Both the TGMD-3 score and the object manipulation score were related to the SRS total score (r=-0.49, -0.45) and ASSS total score(r=0.54, 0.51)(P<0.05). Conclusion Gross motor intervention can improve the motor and social skills of children with autism, and there is a positive correlation between motor ability and social skills in children with autism.

Objective To explore the influence of psychological intervention on the immune function of patients with nasopharyngeal carcinoma. Methods Forty nasopharyngeal carcinoma patients with concomitant radiochemotherapy were divided into intervention group and control group by random digits table method with 20 cases each.Among concomitant radiochemotherapy nasopharyngeal carcinoma patients, intervention group were treated with comprehensive psychological behavior, and control group received only concurrent radiotherapy and chemotherapy. Both groups were investigated by Self-rating Anxiety Scale(SAS)and Self-rating Depression Scale(SDS).Natural killer cells activity were measured by flow cytometry. Results There were no significantly difference in score of SDS and SAS between two confirmed groups(P>0.05).After treatment,the score of SDS and SAS in intervention group were(45.26± 3.83), (42.57 ± 3.75) points, which were significantly lower than those of control group (52.68 ± 3.66), (51.16 ± 3.62) points, the difference was statistically significant(t =6.264, 7.370, P<0.05). Meanwhile, natural killer cell activity between two groups showed no significantly difference (P>0.05). However, the activity of natural killer cells in intervention group was 26.96±9.01,which was higher than that of control group 22.84 ± 7.19, there were statistically significant difference between two groups (t=2.120, P<0.05).There was a positive correlation between the value difference of SDS scores,SAS scores and natural killer cell activity between two groups (r=0.238, P=0.006; r=0.527, P=0.003). Conclusions Comprehensive psychological intervention can significantly not only improve the depression and anxiety of nasopharyngeal carcinoma patients,but also enhance the activity of natural killer cells,which help maintain the leukocyte level of patients.

Mixed lineage kinase domain-like protein (MLKL) is a pseudokinase with a kinase domain, which plays an important role in the regulation of necroptosis. After cerebral ischemia, MLKL, as the substrate protein of the receptor-interacting protein 3, undergoes oligomerization and phosphorylation, and then translocates from the cytoplasm to the plasmalemma, causing mitochondrial division and cell membrane rupture. MLKL can also mediate the inflammatory response after cerebral ischemia by inducing necroptosis and directly activating inflammasomes, thereby aggravating brain injury. Therefore, to clarify the biological characteristics of MLKL and its role and mechanism in cerebral ischemia is very important for the treatment of cerebral ischemia.
