Objective To study effect of a novel schiff base ruthenium coordination compound on cell proliferation and apoptosis of gastric cancer SGC-7901 cell.Method Gastric cancer SGC-7901 cell were divided into four groups according to different treatment of novel schiff base ruthenium coordination compound (concentration of 10, 30, 50μmol/L) and blank group with DMSO.Cell proliferation was detected by MTT assay, cell apoptosis and cell cycle were analysed by flow cytometry.ResuIts MTT results showed the inhibitory effect of novel schiff base ruthenium coordination compound on SGC-7901 cell enhanced with the increase of its concentration, and inhibitory rates were higher than that of blank group at 24, 48, 72 h.Flow cytometry results showed the apoptosis rate of novel ruthenium coordination compound groups of 10, 30, 50μmol/L were (17.64 ±1.21)%, (26.47 ± 0.61)%, (55.63 ±1.49)%, respectively, all higher than that of blank group (P<0.05).The cell proportion of G1 phase increased with the increasing of the novel schiff base ruthenium coordination.ConcIusion A novel schiff base ruthenium coordination compound could inhibit the growth of gastric cancer SGC-7901 cells, promote apoptosis and arrest gastric cancer SGC-7901 cells at G1.

Ankylosing spondylitis (AS) is a chronic inflammatory disease characterized by inflammation of the sacroiliac joints and the spinal attachment point and is the most common type of spondyloarthritis (SpA). The pathogenesis of AS is related to both the immune system and the skeletal system. The main pathological changes include enthesitis, osteogenesis changes, osteolytic bone destruction, and immune system changes. Bone cells interact with immune cells, secrete a series of inflammatory factors, and jointly regulate the pathogenesis of AS. The imbalance of various immune cells in AS and the changes in inflammatory cytokines lead to a disorder of bone metabolism. At the same time, the osteocytes express various inflammatory cytokines, which leads to an imbalance of the immune system. The interaction between the immune system and the skeletal system has become a hot spot in the pathogenesis of AS. Understanding the bone immunological mechanism of AS will help to understand the exact pathogenesis of the disease and explore new treatment methods for it. In this review, the changes of various immune cells and inflammatory cytokines in AS and their effects on the skeletal system, as well as the changes of various osteocytes in the skeletal system and their effects on the immune system, were reviewed, and the latest progress in the treatment of AS was summarized.

Objective To explore the effect of virtual reality video games on gross motor skills of children with cerebral palsy.Methods The 56 patients with cerebral palsy treated in the Fifth Affiliated Hospital of Zhengzhou University from April 2015 to April 2017 were selected as the subjects.The age of the patients was (5.4 ± 1.2) years old (5-7 years old).According to the results of Gross Motor Function Classification System (GMFCS) assessment,all patients belonged to level Ⅰ-Ⅱ.All patients were randomly divided-into 2 groups:video-game group and conventional exercise group for 6 weeks of functional exercise.The evaluation criteria included the average exercise time,the 6-minute walk test (6MWT) and general motion function challenge module (GMFMS-CM) measurement and evaluation.Results The average exercise time of video games in video game group was (44.2 ± 6.1) minutes.The encouragement from the therapists in the intervention process was very important.The technical problems also had a relatively high proportion,and the technical guidance and training should be emphasized at the beginning of the study.The average score of the Likert scale showed that the practice program was suitable for the patients;GMFMS-CM in video game group was significantly higher [mean difference was 4.8,the quartile (IQP) was 4.68,Z =-2.025,P =0.035],while conventional exercise group showed an increasing trend which was not significantly different;6MWTshowed a significant increase in the mean level of video-game group (mean difference was 69.1 m,IQR was 40.2 m,Z =-2.108,P =0.045),conventional exercise group was significantly lower than the average level of subjects in video-game group and there was no significant change in the study period.Conclusion For children with cerebral palsy,routine functional rehabilitation exercise plus family-style virtual reality video game practice,on the one hand to improve patient compliance with the treatment,on the other hand can significantly improve their physical movement function,which is conducive for the patients' quality of life and self-care ability.

Objective To evaluate the efficacy and safety of Qingpeng ointment for the treatment of localized eczema in children.Methods A multicenter,randomized,open-labeled,tacrolimus 0.03％ ointment-controlled clinical trial was conducted.A total of 442 children with localized eczema were enrolled into this study,and divided into 2 groups to topically apply Qingpeng ointment (Qingpeng group) and tacrolimus 0.03％ ointment (tacrolimus group) respectively twice a day for 2 weeks.The children were followed up before the treatment and 1,2 weeks after the treatment,and the efficacy and safety were evaluated at the same time.Results Clinical data from 426 children were included in the efficacy analysis.At 1,2 weeks after the treatment,there were no significant differences in the response rate between the Qingpeng group and tacrolimus group (1 week after the treatment:78.92％ vs.81.77％,x2 =0.545,P =0.460;2 weeks after the treatment:98.65％ vs.97.54％,x2 =0.721,P =0.396).However,the pruritus scores at 1,2 weeks after the treatment were both significantly lower in the Qingpeng group than in the tacrolimus group (1 week:F =14.001,P =0.000;2 weeks:F =11.252,P =0.001).At 1 week after the treatment,the incidence rate of adverse reactions was significantly lower in the Qingpeng group than in the tacrolimus group (P ＜ 0.05).Mild itching,burning sensation and other local irritant sensations were the most common adverse reactions.Conclusion Qingpeng ointment is safe and effective for the treatment of localized eczema in children with good tolerability.
