This paper was aimed to study effects of diosgenin on expressions of activator protein-1 (AP-1) and vascular endothelial growth factor (VEGF) in synovial tissues of collagen-induced arthritis (CIA) rats induced by bovine type II collagen, in order to investigate the possible mechanism of herbal medicine diosgenin in the treatment of rheumatoid arthritis (RA). After the CIA rats models were successfully established, rats were randomly divided into the blank control group, CIA model group, diosgenin group, and positive medicine control (tripterygium) group. The in situ hybridization was used to detect the expressions of AP-1 (c-fos and c-jun) in synovial tissues of the knee joint. The real-time PCR was used to detect the VEGF mRNA expression in synovial tissues of rats’ knee joints. The results showed that c-jun and c-fos, VEGF mRNA expressions in synovial tissues of rats’ knee joints were obviously higher than that of the blank control group (P<0.01). After treatment of diosgenin and tripterygium, the expressions of c-jun and c-fos, VEGF mRNA were significantly reduced (P<0.01). It was concluded that diosgenin may regulate the expression of VEGF in synovial tissues through c-jun and c-fos of AP-1 in order to inhibit synovial angiogenesis for the treatment of RA.

In the marketing theory, service disparity model is a simple effective tool, capable of figuring out the five clusters of reasons leading to service failure. This article applies it in the community health service domain. Through the efforts of healing the five gaps in service delivery, including Consumer expectation-management perception gap, Management perception-service quality specification, Service quality specifications-service delivery gap Consumer expectation-management perception gap and Service delivery-external communications gap, we hope to improve the community health service quality radically.

Objective To investigate the pregnancy opportunity and outcome of patients with sysmetic lupus erythematosus (SLE).Methods We carried out a retrospective analysis of the clinical information of patients who suffered from SLE complicated with pregnancy and were hospitalized to People's Hospital of Peking University from December of 1992 to February of 2012.Chi-square test were used for statistical analysis.Results Forty-nine cases of patients with SLE complicated with pregnancy had 52 pregnancies in total.In 27 cases of planned pregnancies,24 cases(89％ )resulted in live births and 5 cases( 18％ ) had flares during pregnancy.Of the 24 live births,3 cases( 12％)were premature deliveries and 4 cases(17％) had low birth weight infants.In 25 cases of unplanned pregnancies,12 cases (48％) resulted in live births and 20 cases (80％) had flares during pregnancy.Of the 12 live births,6 cases(50％ ) were premature deliveries and 6 cases (50％) were low birth weight infants.The patients in the planned pregnancy group tended to have flares during pregnancy more frequently than those in the unplanned group (P＜0.01),the former were more likely to have live births than the latter (P＜0.01) and were less likely to have premature delivery (P＜0.05).Conclusion Patients with SLE should have planned pregnancy and need collaborative supervision of both rheumatology and immunology department and obstetric department to improve live birth rate,decrease premature delivery and the activity of SLE during pregnancy.

Anterior ischemic optic neuropathy (AION) is the ciliary artery-circulatory disorders for the supply of optic nerve head area before the sieve plate prozone and sieve plate district, result in the insufficient blood supply of the optic nerve head and ischemia hypoxia, edema. Clinical manifestations of the type with non-artery inflammatory neuropathy and artery inflammatory neuropathy, which would both eventually lead to the irreversible damage to the optic nerve. In the early phase of AION, the main method is giving a glucocorticoids intravenous drip and a periglomerular injection (or retrobulbar injection) in time, but using the glucocorticoids for a long time or in quantity can cause a series of complications. Therefore, the combination of traditional Chinese and western medicine treatment of AION has become more and more significant in clinic.

Objective To investigate the effect of intratumor injection of 131 I 3H11 for gastric cancer (GC). Methods 16 patients with GC subjected to endoscopic intratumor injection of 131 I 3H11 as a treatment group; 6 GC patients with FAM chemotherapy as a control group. Histological examination of the postoperative specimens of the two group were comparated. Results In treatment group, 75.0%(12/16) of cases were found to have morphological changes with karyopyknosis, karyorrhexis, coagulation of cytoplasm, and invasion of lymphocyte in mesochyma. Most of these changes were medial; but in control group no obvious morphological change was found. Conclusions The results suggest that GC subjected to endoscopic intratumor injection of 131 I 3H11 preoperatively has promising application in the clinic.

ObjectiveTo explore the diagnosis and treatment of acute mesenteric ischemia.MethodsClinical data of 12 cases with acute mesenteric ischemia diagnosed by both operation and pathology were analyzed retrospectively.ResultsThe cases were mainly aged patients accompanied by cardiovascular disease and easily developed to strangulative intestinal obstruction. The mortality rate of this disease was very high.ConclusionThe early diagnosis with suitable techniques and prompt treatment are the keys to the management of this disease.

In order to construct a eukaryotic co-expression plasmid containing membrane-anchored Sjcl4FABP and Sjc26GST genes and identify their expression in vitro, Sj14 and Sj26 genes were obtained by RT-PCR with total RNA of Schistosoma japonicum adult worms as the template and cloned into eukaryotic expression plasmid pVAC to construct recombinant plasmids pVAC-Sj14 and pVAC-Sj26. Then a 23 amino-acid signal peptide of human interleukin-2 (IL-2) upstream Sj14 or Sj26 gene and a membrane-anchored sequence containing 32 amino-acids of carboxyl-terminal of human placental alkaline phosphatase (PLAP) downstream were amplified by PCR as the template of plasmid pVAC-Sj14 or pVAC-Sj26 only to get two gene fragments including Sj14 gene and Sj26 gene. The two modified genes were altogether cloned into a eukaryotic co-expression plasmid pIRES, resulting in another new recombinant plasmid pIRES-Sj26-Sj14. The expression of Sj14 and Sj26 genes was detected by RT-PCR and indirect immunofluorescent assays (IFA) when the plasmid pIRES-Sj26-Sj14 was transfected into eukaryotic Hela cells. Restriction enzyme analysis, PCR and sequencing results revealed that the recombinant plasmids pVAC-Sj14, pVAC-Sj26 and plRES-Sj26-Sj14 were successfully constructed and the expression of modified Sj14 and Sj26 genes could be detected by RT-PCR and IFA. A bivalent membrane-anchored DNA vaccine encoding Sj14 and Sj26 genes was acquired and expressed proteins were proved to be mostly anchored in cellular membranes.

Aim To investigate the effect of 96 h paradoxical sleep deprivation(PSD) on learning & memory ability of rats and the concomitant gene expression change in the rat hippocampus.Methods PSD model was established by Modified Multiple Platform Method(MMPM).Learning and memory ability of the PSD model was assessed through hexagonal maze compared with the control, and the gene expression in hippocampus of each group was detected by gene chip technology.After that, GO and KEGG enrichment analysis were applied to determine the changes of the gene expression in PSD model compared with the control.Results PSD affected the memory consolidation process in rats.The gene chips showed that 100 genes expressed differently in the hippocampus of PSD model compared with the control, and among them, 25 genes were up-regulated and 75 genes down-regulated.The up-regulated genes mainly involved in cell growth and differentiation, learning and memory, inflammation, oxidative stress, and biological processes such as synaptic transmission, while the down-regulated genes mainly involved in immune response, central nervous system development, synaptic transmission, metabolism, signal transduction, neurotransmitter secretion, cell apoptosis, and so on.KEGG analysis showed that genes differentially expressed mainly involved in cGMP-PKG, metabolism, NF-kappa B and Pathways in cancer, and so on.Conclusion In rats, PSD leads to memory deficit, as well as a variety of gene expression changes in hippocampus of the PSD model.
