Chemokine is a kind of cytokine that induces cell transport to inflammation sites. It plays an important role in controlling the differentiation, development and directed migration of immunocytes. CCL20 is one of the important members of chemokine family, and it belongs to CC subfamily. Its receptor is CCR6. CCL20 can be expressed in activated monocytes, T lymphocytes, dendritic cells and endothelial cells, and CCR6 can be expressed in liver, lung, and lymphoid tissues. The expression of CCL20 can be induced by tumor necrosis factor α (TNFα), interleukin 1β (IL-1β), IL-17, CD40 ligand and interferon γ (IFN-gamma;). In summary, CCL20 plays an important role in tumor growth, invasion and metastasis (mainly refers to intrahepatic metastasis). Copyright© 2011 by TUMOR.

Jaundice can occur in most neonates.Most jaundice is benign,but beacuse of the potential toxicity of bilirubin,newborn infants with severe hyperbilirubinemia can develop acute bilirubin encephalopathy or kernicterus.In October 2004,American(academic) of pediatrics produced the latest guideline for newborn jaundice aim to reduce the incidence of acute bilirubin encephalopathy or kernicterus and avoid unnecessary costs or treatment.The latest guideline emphasizes the important of successful breastfeeding,time of jaundice developed,assessment for the risk of severe hyperbilirubinemia,close follow-up,and prompt intervention when indicated,provide a framework for the prevention and management of hyperbilirubinemia in newborn infants of 35 or more weeks of gestation.Some new view in the latest guideline may be helpful to us.

ObjectiveTo investigate the understanding of stroke among stroke patients and promote the direction of rehabilitation.MethodsA survey was carried out among 80 stroke patients by questionnaire.Results42.5% of those patients knew nothing about the risk factor of stroke and the rate of right behavior related to maintain health was relatively low. The rate of satisfaction with rehabilitative direction was only 66.3% though 98% patients had experienced that direction.ConclusionIntensive and continuous direction of rehabilitation is necessary for the stroke patients. Comprehensive health education should be given to those patients to ensure their best self care and improve their quality of living.

Background and purpose:Pterostilbene is a natural antioxidant, whose role in retinoblastoma remains unclear. The aim of this study is to probe the effects of pterostilbene on the proliferation, apoptosis and autophagy in retinoblastoma WERI-Rb-1 cell lines.Methods:Cell counting kit-8 (CCK-8) assays were used to analyze the effects of pterostilbene on the proliferation of WERI-Rb-1 cells. Apoptosis rate was determined by Annexin V/PI. Autophagic vacuoles were observed by acridine orange staining. LC3 and P62 protein expressions were determined using Western blot.Results:Pterostilbene significantly inhibited the proliferation of WERI-Rb-1 cells (P<0.01). The cell viability were (93.02±0.47)%, (55.10±2.04)% and (30.33±1.45)% after WERI-Rb-1 cells were treated with 25, 50 and 100 μmol/L pterostilbene for 24 h, and the cell viability were (88.38±3.70)%, (53.37±1.17)%, (29.60±1.05)% after WERI-Rb-1 cells were treated with 50 μmol/L pterostilbene for 12, 24 and 48 h. Pterostilbene induced cell apoptosis (P<0.01), the apoptosis rates of control group, 24 h treated group and 48 h treated group were (4.08±0.79)%, (13.44±2.12)% and (23.49±2.01)%. Pterostilbene induced autophagy of WERI-Rb-1 cells, increased LC3 expression, downregulated P62 expression and increased the number of autophagic vacuoles in WERI-Rb-1 cells (P<0.01). 3-MA and Beclin1 were able to rescue pterostilbene-induced cell death (P<0.01). After 3-MA was used to blunt autophagosome formation, the apoptosis rate markedly decreased in 3-MA+pterostilbene-treated cells compared with cells treated with pterostilbene alone [(12.97±2.09)%vs (8.35±1.11)%], and after siRNA was used to knockdown Beclin1, the apoptosis rate had the same change [(13.80±2.19)%vs (9.62±0.52)%].Conclusion:Pterostilbene can inhibit the proliferation of WERI-Rb-1 cells and induce cell apoptosis via autophagy activation.

Objective To investigate the effect of teaching mode innovation based on the tech-nology of digital orthopedic in orthopedic clinical teaching for eight-year program medical students. Methods 40 eight-year program medical students who took part in orthopedic clinical trainee in the 2015 school year were chosen and divided into two groups:traditional teaching group and digital tech-nology teaching group. The digital technology teaching group adopted a digital model of orthopedic technology, printing aids, use of auxiliary aids and simulate actual cases operative teaching while an-other group used traditional teaching. After the novitiate, questionnaire investigations were used to evaluate the effect of the orthopedic clinical teaching in both groups. At the same time an examination after the course was used to examine the teaching effect of the two groups, and SPSS 19.0 software was used to do chi-square test and t test to the result of the examination of both groups. Results Compared with the traditional teaching group students, the digital technology teaching group students more agreed with the new teaching mode for their interest in learning and hands-on ability bring positive influence (P<0.05), overall satisfaction of teaching method was significantly higher (P=0.03). The operation ex-amination result [(92.1±9.1) vs. (70.5±9.6)] and the comprehensive examination result (84.6±10.1) vs. (72.3±10.6)were more outstanding, the t test showed that the difference was statistically signifi-cant (P<0.05). Conclusion Teaching mode innovation based on the technology of digital orthopedic in eight-year program medical students has showed obvious advantages in orthopedic clinical teaching, which can stimulate students' interest in learning, improve the teaching effect and have broad applica-tion prospects in orthopedic clinical teaching.
