90 ). ③For the experimental group at baseline, DQ of the gross movement was the highest (71.5?10.5), while that of the other four areas were similar (fine movement 56.7?10.4, adaptability 59.6?12.5, language 54.3?11.7, social 56.8?14.7).Conclusions:Early intervention had significant effects for the development of children with mental retardation, which medicine has less role.

Object: To explore the effects and the influent agents of early education on the healthy termed infants. Methods: 52 healthy termed infants voluntary to the exercise center as experimental group were early educated. The other 52 infants as control group were in the same elementary conditions comparing to the experimental group. The experimental group was trained the corresponding projects and examined DQ at the beginning and the 3 rd,6 th,9 th month after training. The control group was only examined DQ at the beginning and after 9 months. Results:①At the 9 th month after training, DQ of the experimental group was improved 21.9?13.6, which was much 7 times higher than that of the control group, which was improved 3?3.0 (P

Objective To understand the molecular mechanism by which protein kinase C? mediates multidrug resistance of human glioma cell line SHG-44.Methods SHG-44/ADM was constructed by stepwise concentration increasing method and intermittent administration method.SHG-44/WT and SHG-44/ADM were treated by PKC? reactivator PMA and PKC? inhibitor staurosporine,then the expressions of PKC? and MDR-1 were detected by Western blotting,the PKC? activity was assayed by kinase,and ADM accumulation was determined by fluorescence spectrometry.Results PMA increased PKC? activity and MDR-1 protein expression and activity.Staurosporine was able to block PKC? activity and decrease MDR-1 expression and activity.Conclusion Multidrug resistance in human glioma cells is mediated by PKC? via MDR-1 pathway.

Objective To systematically review the efficacy and safety of photodynamic therapy (PDT) and intravitreal vascular endothelial growth factor (VEGF) inhibitors in the treatment of polypoidal choroidal vasculopathy (PCV),and to investigate the primary treatment tentatively.Methods A systematic search of Pubmed,Embase,the Cochrane Library and the Wanfang Data was performed to identify all comparative studies that compared the outcomes of PDT alone,intravitreal VEGF inhibitors alone and combined intravitreal VEGF inhibitors and photodynamic therapy.Outcomes of interest included the regression and recurrence rate of polypoidal lesions,best corrected visual acuity (BCVA),central retinal thickness (CRT),therapeutic times,and the occurrence rate of adverse events.2 randomized controlled trials (RCT) and 19 non-RTCs were identified.According to treatment methods,the data extracted was classified to 3 groups,analyzed with odds ratio (OR),weighted mean difference (WMD) and 95％confidence interval (95％CI).Results Meta-analysis suggests that the regression rate of polypoidal lesions (OR=0.34,0.07;95％CI=0.13-0.88,0.02-0.36) and BCVA (WMD=0.25,0.11;95％CI=0.14-0.36,0.01-0.21) in combined therapy group were significantly better than those in PDT group and intravitreal VEGF inhibitors group (P＜0.05).The recurrence rate of polypoidal lesions in PDT group was significantly lower than intravitreal VEGF inhibitors group (OR=0.35,95％CI=0.16-0.74,P=0.006).BCVA (P=0.025) and the occurrence rate of adverse events (OR=60.36,95％CI=6.04-603.50,P=0.000 5) in intravitreal VEGF inhibitors group were significant better than PDT group.Conclusions Combined treatment appeared to be superior to PDT alone or intravitreal VEGF inhibitors alone.Combined treatment takes priority over all others in the primary treatment of PCV.

Balb/c mice were immunized by intraperitoneal iniection of group A erythrocytes. Immunized spleen cells were fused with Sp2/0 murine myeloma cells from the solid tumour. After 10～15 days of incubation at 37℃ CO_2, the supernatants were screened for the agglutinabal antibodies. Three hybridoma cell lines secreting high titer and specific monoclonal anti-A antibodies were established.These hybridoma cells have the ability of constant seceting antibodies which belong to the IgM class. The specificity monocloal anti-A sera was the same as the human anti-A sera.

Objective To study the effects of extracellular-signal regulated kinase mitogenactivated protein kinase (ERK-MAPK) signaling pathway inhibition on histone phosphorylation and the related gene expression in human colorectal cancer cells.Methods Two human colorectal cancer cell lines (SW1116 and HCT116) were cultured and treated with gradient(0,20,40/μmol/L) doses of ERK-MAPK signaling pathway inhibitor U0126.Cell viability was determined by cell counting kit 8 (CCK-8) assay.Cell cycle distribution was assessed by flow cytometry.The expression levels of histone H3 kinases including ribosomal S6 serine-threonine kinase (RSK-2) and mitogen-and stressactivated protein kinase 1 and 2 (MSK1 and MSK2),and the levels of histone H3 (Ser10) phosphorylation and c-Fos protein were detected using Western blotting.Results Treatment of these two human colorectal cancer cell lines with ERK-MAPK inhibitor resulted in a time and dose-dependent inhibition of cell proliferation significantly. Proliferation rate of HCT116 was reduced to 47% at 72 hours after 40/μmol/L U0126 treatment. Cell cycle analysis showed that the percentage of phase G0/G1 cells significantly increased (P<0. 01) and the percentage of phase S cells decreased (P<0.01) after treatment with ERK-MAPK inhibitor. The expression of MSK1 and RSK2 reduced obviously in both of human colorectal cancer cell lines treated with U0126, which resulted in a 28% and 40% reduction of levels of MSK1 and RSK2 as compared with control HCT116 cells respectively,while no detectable change in the expression of MSK2 was found. Consistent with this, the expression level of histone H3 (ser10) phosphorylation was markedly down-regulated by ERK-MAPK inhibitor, and the related protein c-Fos expression decreased accordantly. Conclusions Decreased ERK-MAPK signaling pathway may reduce histone H3 (Ser10) phosphorylation via suppression of the activity of histone H3 kinase including MSK1 and RSK2, but not MSK2, consequently decrease the expression of c-Fos protein, which results in the inhibition of colorectal cancer cells proliferation.

Military hygiene is one of compulsory courses for undergraduates majored in clinical medicine in military colleges. Aiming at the disconnection between theoretical and practical ability in the traditional teaching process and combining with professional features of military hygiene, teaching reform should give priority to curriculum standards, human resource construction, teaching content and method, teaching quality assessment and feedback system. Meanwhile, teaching idea of‘learning to use’ should be strengthened and teaching scheme in line with the actual needs of military health service security work should be put forward in order to provide new ideas for training military health personnel.

Codon usage bias is an important characteristic of genetic information transfer in organisms. Analysis of codon usage bias of different species is important for understanding the rules on genetic information transfer. The previous method for analysis of codon usage bias is mainly based on genomic data. However, this method is greatly limited, because the genome sequences of higher organisms are still not available up to now. In this study, we found that we could obtain the same optimal codons of Ganoderma lucidum (Curtis: Fr.) P. Karst based on its whole genomic data or large-scale transcriptomic data from its liquid-cultured hyphae, primordium and fruiting body, separately. This result indicated the feasibility to understand the codon usage bias based on the large-scale transcriptomic data. By calculating the proportion of rare codons of Escherichia coli and Saccharomyces cerevisiae in 26 terpene synthases (TS) of G. lucidum, we found that the rare codons of S. cerevisiae have a higher proportion in TS genes, while the rare codons of E. coli have relatively lower, suggesting that the TS genes of G. lucidum are possibly more difficult to be expressed in S. cerevisiae than in E. coli. Chemical synthesis of TS genes according to the yeast optimal codons will be an effective way to solve the problem on the mismatch of gene codon bias between the foreign genes and the host strain.

RNA-Sequencing (RNA-Seq) is a newly-developed method in transcriptome research, it can afford more accurate transcription information and be more quickly by using Next-generation Sequencing (NGS) technology. RNA-Seq has been widely used in various biological fields. Genuine traditional Chinese medicines (TCM), with good quality and therapeutic effect, were always praised highly and used by famous physicians. The geo-herbalism formation of TCM is based on the product of the gene expression at specific space and time. So it has been a research hotspot to analyze the mechanism of biosynthesis through RNA-Seq in the study on the secondary metabolism of medicinal plant. This article mainly illustrates the RNA-Seq and its advantages, it also discusses the potential application in genuine TCM, and it can provide useful information for other researchers.
