IL-17 is the cytokine secreted by the subgroup of CD4+T cells named Th17.The differentiation,proliferation and cytokine secretion of Th17 are regulated by TGF-?,IL-6,IL-15 and IL-23.IL-17 modulates the production and secretion of proinflammative factors,CXCs,affecting the transfer of neutrophil,the activation and the absorption of bone.It suggests that IL-17 also plays an important role in the pathogenesis of autoimmune diseases.

Objective This article intends to study the varieties of the prenancy associated with cardiac dis-ease, how to treat with the perinataI period and the pregnancy outcome. Methods (1)Sum up 112 sufferers' clinical data of the pregnancy associated with cardiac disease in this hospital from 1998 to 2007. (2)Analysc the varieties of the pregnancy associated with cardiac disease according to the sufferers' pathogeny. (3)Divided into two groups ac-cording to the state of an illness,80 cases are the heart function Ⅰ～Ⅱ (group A) ,32 cases are heart function Ⅲ～Ⅳ (group B) ,and contrast the two group sufferers' pregnancy outcome. Results (1)The varieties of the pregnancy associated with cardiac disease are mainly the congenital heart disease and the incompetency heart valve. (2)The rate of the uterine-incision delivered sufferers in group B is 93.8 % ,while the other one of the uterine-incision deliveredsufferers in group A is 70.0%. Compared A to B, the difference is obvious( P < 0.01 ). (3)No pregnant women is found dead in group A. 2 pregnant women were dead in group B, who was a sufferer with high blood-preasure heart-disease during pregnancy and eclampsia. (4)The dead rate of the premature delivery, neonatal asphyxia and the peri-natal in group B is 43.8% ,25.0% and 12.5%. It is obviously higher than that in group A(12.5% ,2.5% ,0).Compared A to B, the difference is obvious( P < 0.01 ). Conclusion The pregnancy associated with cardiac disease is the cause which leads to the death of the pregnant women and the perinatal babies. The canonical prenatal diagnosis,termination of pregnancy in time and the cooperation with relative sciences can improve the pregnancy outcome.

Objective To introduce the illness perception questionnaire-memory (IPQ-M) and translate it into Chinese and to evaluate its reliability and validity.Methods The Chinese version of IPQ-M was translated from the original,back translated and adjusted for culture adaptation.A total of 152 community-dwelling people with subjective memory complaints (SMCs),who were aged 50 years or above,were investigated with the Chinese version of IPQ-M.40 participants among them were re-evaluated 2 weeks later.Results Exploratory factor analysis got 9 factors which could explain 70.757％ of the total variance.The factor loading of each item on the corresponding factors was higher than 0.4.The correlation between Chinese version of IPQ-M and GDS were-0.208 to 0.763 (P＜0.01).The Cronbach's α coefficient was 0.872,the testretest reliability was 0.894,and the Spearman-Brown split coefficient was 0.890.Conclusion The Chinese version of IPQ-M has good reliability and validity,and it can be used in Chinese elderly people with SMCs.

Objective To investigate the characteristics of everyday memory of adults with subjective memory complaints (SMC),and probe into the correlation between everyday memory function and life quality.Methods Through convenience sampling,150 adults with SMC were face-to-face interviewed by an investigator,with demographic characteristics collected,and the cognition function,everyday memory function and life quality were also assessed during the interview.Results Among the 150 adults with SMC,the impairment rate of everyday memory function reached 96％,and the median score of RBMT-II was 16.00 (interquartile range 6.00),indicating a low level of everyday memory function,with the Name andDelayed recall Story items having lower scores.All participants were divided into two groups according to cognitive status,with 67 (44.70％) adults having normal cognitive function and 83 (55.30％) impaired cognitive function.After comparison,significant differences were found in the total score of RBMT-II and scores ofFaces recognition andDelayed recall Story between the two groups (P＜0.05).In all dimensions of SF-36,the median score of general health dimension for the 150 adults was 55.00 (inter-quartile range 31.25).The Spearman rank correlation analysis showed that the scores of several dimensions in RBMT-II were positively correlated with the scores of several dimensions in SF-36 (P＜0.05).Conclusion Everyday memory function of people with SMC was positively CorTelated with their life quality.

Objective To investigate that p53 expression in fibroblast-like synoviocytes (FLS) and its effects on CD4+ T lymphocytes from active rheumatoid arthritis (RA) patients. Methods Human FLS was transfected with p53siRNA and cocultured with CD4+ T lymphocytes from active RA patients. The expression of osteoprotegerin and IL-6 secretion was detected in the transfected FLS. In addition, the expressions of IFN-γ, IL-17, IL-4 and CD25 as well as mRNA levels of IFN-γ RORγt, IL-17 and Foxp3 in cocuhured CD4+ T lymphocytes were also measured. Results IL-6 secretion decreased in p53-inhibited FLS while osteopro-tegerin expression was not altered, p53-inhibited FLS could significantly increase IL-17 and IFN-γ expres-sions. It also upregulated Foxp3 expression though had no effect on CD4+CD25high T lymphocytes. Conclusion p53 expression in FLS regulates Th1 and Th17 cells of RA patients, and therefore participate in the pathogenesis of RA.

An ever-growing number of resources on model organisms have emerged with the continued development of sequencing technologies. In this paper, we review 13 databases of model organisms, most of which are reported by the National Institutes of Health of the United States (NIH; http://www.nih.gov/science/models/). We provide a brief description for each database, as well as detail its data source and types, functions, tools, and availability of access. In addition, we also provide a quality assessment about these databases. Significantly, the organism databases instituted in the early 1990s––such as the Mouse Genome Database (MGD), Saccharomyces Genome Database (SGD), and FlyBase––have developed into what are now comprehensive, core authority resources. Furthermore, all of the databases mentioned here update continually according to user feedback and with advancing technologies.

With the rapid development of sequencing technologies towards higher throughput andlower cost, sequence data are generated at an unprecedentedly explosive rate. To provide an efficientand easy-to-use platform for managing huge sequence data, here we present Genome Sequence Archive (GSA; http://bigd.big.ac.cn/gsa or http://gsa.big.ac.cn), a data repository for archiving rawsequence data. In compliance with data standards and structures of the International Nucleotide Sequence Database Collaboration (INSDC), GSA adopts four data objects (BioProject, Bio Sample,Experiment, and Run) for data organization, accepts raw sequence reads produced by a variety of sequencing platforms, stores both sequence reads and metadata submitted from all over the world,and makes all these data publicly available to worldwide scientific communities. In the era of bigdata, GSA is not only an important complement to existing INSDC members by alleviating theincreasing burdens of handling sequence data deluge, but also takes the significant responsibilityfor global big data archive and provides free unrestricted access to all publicly available data insupport of research activities throughout the world.

Objective To study the memory disorder perception characteristics of subjective memo-ry complaints(SMCs)and to analyze the influencing factors. Methods 302 subjects conforming to the in-clusion criteria were selected.All the subjects completed the illness perception questionnaire-memory of Chi-nese version(IPQ-M). Results (1)There was no statistical difference between the score of social compari-son(2.95±0.78)and the middle value 3.The differences between the score of the remaining dimensions of memory impairment perception(timeline acute/chronic(3.57 ± 0.89),consequences(2.24 ± 0.77),timeline stability/decline(3.71±0.88),personal control(blame)(3.61±0.92),personal control(helplessness)(3.31± 0.73),emotional representation(2.29 ± 0.70),treatment control(2.78 ± 0.67),illness coherence(3.14 ± 0.64))and the middle value 3 were statistically significant(all P<0.05).(2)Gender,education level,living condition,marital status,economic condition,family history of dementia and knowledge education of dementia were the influencing factors of memory perception of SMCs. Conclusion The memory complaining people are less aware of the related knowledge of memory decline,and there are more errors and negative percep-tions.The factors that affect the perception of memory disorders are complex.

Objective: To investigate the efficacious and safe therapy for urothelial carcinoma patients with liver metastasis. Methods: A total of 42 urothelial carcinoma patients with liver metastasis from December 2006 to December 2016 at Department of Renal Carcinoma and Melanoma in Beijing Cancer Hospital were included in this retrospective study. All patients were divided into three groups, and treated with paclitaxel plus gemcitabine, paclitaxel plus gemcitabine and cisplatin, or paclitaxel plus gemcitabine combined with transcatheter arterial chemoembolization (TACE), respectively. The treatment continued until disease progression or intolerable adverse reactions occurred. The efficacy and treatment-related adverse reactions in different groups were analyzed specifically. Results: For the 42 patients, the median progression-free survival time (PFS) was 2.0±0.7 months [95% confidence interval (CI): 0.6-3.4], and the median overall survival time (OS) was 6.1±1.7 months (95% CI: 4.1-9.9). For the 12 patients receiving TACE combined with systemic chemotherapy, the median PFS was 7.1 ±0.7 months (95% CI: 5.7-8.5), the median OS was 14.1 ±3.0 months (95% CI: 8.3-19.9), which were statistically different from those in systemic chemotherapy group (both P < 0.01). The patients could tolerate TACE combined with systemic chemotherapy. The common adverse effects were gastrointestinal reaction at grade 1-2, upper abdominal pain and leukopenia. Conclusion: TACE combined with systemic chemotherapy is an efficacious and safe treatment regimen for urothelial carcinoma patients with liver metastasis.

On December 27, 2018, the first domestic anti-PD-1 antibody, toripalimab, was approved by the State Food and Drug Ad-ministration for the treatment of advanced melanoma after the failure of standard treatment. This represented a major breakthrough in the field of biopharmaceuticals in China and laid the foundations for pharmaceutical research and development in the field of tu-mor immunotherapy. In this article, we summarize the clinical research of the treatment of melanoma, the application of toripalimab in this field, and the global development of other anti-PD-1 antibodies, to provide guidance for the research and treatment of melano-ma in China.
