Stroke is a hi-attack rate,hi-multilation rate and hi-death rate disease.More than 70 percent patients with stroke remain functional disturbance,which destroy their quality of life and bring them heavy burden.The early multidisciplinary rehabilitation treatment,rehabilitation care,family rehabilitation training and application of new technology are the major strategies in kinds of rehabilitation treatment on stroke patients.The clinical researches have showed that the effect of multidisciplinary rehabilitation treatment is obviously better than simple treatment.So these therapeutic regimens have wonderful prospect and valuable generalization.

DNA barcoding is an effective technique in species identification. To determine the candidate sequences which can be used as DNA barcode to identify in Papaver genus, five potential sequences (ITS, matK, psbA-trnH, rbcL, trnL-trnF) were screened. 69 sequences were downloaded from Genbank, including 21 ITS sequences, 10 matK sequences, 8 psbA-trnH sequences, 14 rbcL sequences and 16 trnL-trnF sequences. Mega 6.0 was used to analysis the comparison of sequences. By the methods of calculating the distances in intraspecific and interspecific divergences, evaluating DNA barcoding gap and constructing NJ and UPMGA phylogenetic trees. The sequence trnL-trnF performed best. In conclusion, trnL-trnF can be considered as a novel DNA barcode in Papaver genus, other four sequences can be as combination barcode for identification.

Objective To investigate the comprehensive prevention strategy in the prevention of oral mucositis (OM) during allogeneic hematopoietic stem cell transplantation (HSCT). Methods A total of 721 patients who received HSCT from January 2010 to December 2011 at the Institute of Hematology, Peking University were enrolled. All the patients received the comprehensive prevention strategy of OM. Results A total of 315 patients (43.7 percents) suffered from OM during HSCT, the median time from HSCT to OM occurrence was 5 days. There were 173 (54.9 percents), 91(28.9 percents), 37(11.7 percents), and 14(4.4 percents) patients suffered from gradeⅠ,Ⅱ,Ⅲ, and IV OM, respectively. Tongue OM was most common. A total of 111 patients suffered from multiple OM (≥2 locations). Multiplicity showed that duration of agranulocytosis≥15 days was the only independent risk factor of OM in HSCT [ hazard ratio (HR) value 1.5, P<0.05 ]. Neutrophil engraftment time≥12 days was significantly associated with prolonged OM (≥8 days) (HR=2.1, P<0.05). Patient age ≥20 was independent risk factor for occurrance of grade Ⅲ-Ⅳ OM (HR=2.7, P<0.05). Conclusions Comprehensive prevention strategy can overcome the risk factors of OM and prevent the occurrence of OM during HSCT.

During oral glucose tolerance test(OGTT),endothelium-dependent vasodilation(EDD)at different time points in impaired glucose tolerance(IGT)group was lower than that in normal control group.EDD at 60 and 120 min in IGT + vitamin C group was higher than that in IGT group(all P＜0.05).There was a negative relationship between blood glucose level and EDD during OGTT in IGT patients.

OBJECTIVE: To establish a multiplex STR genotyping method for autosomal STR and Y-STR loci in forensic biological practice. METHODS: Widely used autosomal STR loci and Y-STR loci were selected. A set of PCR primers was designed, and a 5-dye fluorescent labeled STR multiplex PCR reagent kit was developed. RESULTS: A kit was developed which can simultaneously detect 15 autosomal STR loci, 10 Y-STR loci, and an Amelogenin. CONCLUSION The 15 autosomal STR plus 10 Y-STR kit in combination with capillary electrophoresis method was used to STR genotyping with accurate and reliable results. The new one-step testing kit can potentially be widely used in forensic cases and DNA databank in the future.

Objective To investigate the relationship of the expression of vascular endothelial growth factor (VEGF)and the mi-crovessel density (MVD)with multi-slice spiral CT perfusion imaging.Methods 80 patients with solitary pulmonary nodules under-went perfusion scan by 16-slice spiral CT.Among them,45 diagnosed as lung cancer by pathology were enrolled in the study.After surgery,the slice of the pecimen was selected similar to the corresponding slice of CT images,and the immunohistochemical staining was performed to determine the expression of VEGF and the MVD.Spearman correlation analysis was used to determine the rela-tionship of expression of VEGF and the MVD with CT perfusion parameters.Results There was more expression of VEGF and the MVD in NSCLC.There were positive correlations between VEGF,MVD and BF (both P<0.05).The peak enhancement image (PEI)and TTP have significant correlations with MVD (P<0.05).Conclusion Some parameters of lung CT perfusion imaging are correlated with MVD and VEGF.

To investigate the effects of human anti-BAFF scFv-Fc against the hsBAFF, ICR mice were randomly divided into six groups: control, hsBAFF (1 mg x kg(-1)), hsBAFF (1 mg x kg(-1)) + Ab (1 mg x kg(-1)), hsBAFF (1 mg x kg(-1)) + Ab (2 mg x kg(-1)), hsBAFF (1 mg x kg(-1)) + human IgG (1 mg x kg(-1)) and hsBAFF (1 mg x kg(-1)) + human IgG (2 mg x kg(-1)) groups. The effects of scFv-Fc administration on the proliferation of B lymphocytes were evaluated using an MTT assay. The titres of antibody in the serum and B lymphocytes differentiation were assessed by ELISA and flow cytometry, respectively. The results showed that administration of scFv-Fc to mice injected with hsBAFF significantly prevented human BAFF-induced increases in splenic B cell numbers and serum immunoglobulin levels. Furthermore, this fully human antibody would avoid inducing the human anti-mouse antibody (HAMA) response when used in humans. These findings suggest that the compact antibody may be useful in therapeutic or diagnostic application of the BAFF-associated autoimmune diseases in human.

As an inflammatory skin disease with a gradually increasing prevalence，psoriasis has negatively impacted the quality of life of patients and has attracted widespread attention from the medical community. The pathogenesis of psoriasis can be affected by a variety of genetic，environmental， and immune factors，and cytokine-driven epidermal proliferation，abnormal differentiation，inflammation， and neovascularization contribute to the pathogenesis，involving the interaction between immune and skin cells. However， some pathogenesis is still a blind spot for research，which brings great challenges to clinical treatment. Therefore， the identification of effective targets for psoriasis is critical in the research on psoriasis. Signaling pathways， another hotpot in the research on psoriasis， play an important cellular transduction role in the pathological mechanism of psoriasis and serve as key transduction factors regulating the immune and inflammatory responses to psoriasis. With the in-depth research in the field of network pharmacology and molecular biology， single Chinese medicine and Chinese medicinal compound can exert a therapeutic role by regulating multiple signaling pathways related to psoriasis. In recent years，traditional Chinese medicine （TCM） has achieved good clinical efficacy in the prevention and treatment of psoriasis，such as relieving pruritus，decreasing the area of skin lesions，improving anxiety， and preventing complications， which confirms the credibility of TCM in the understanding and treatment of psoriasis. Despite the rich theoretical and clinical research on the prevention and treatment of psoriasis，studies on the regulation of psoriasis-related signaling pathways and mechanisms of action by TCM are rarely reported. Therefore，the present study reviewed the available research in recent years and introduced the following six major signaling pathways related to psoriasis which are regulated by TCM： Janus kinase（JAK）/signal transducer and activator of transcription（STAT） signaling pathway，mitogen-activated protein kinase（MAPK） signaling pathway，phosphatidylinositol-3-kinases（PI3K）/protein kinase B（Akt） signaling pathway，nuclear transcription factor-κB（NF-κB） signaling pathway，Wnt signaling pathway， and Notch signaling pathway.
