This article was aimed to study the factors associated with sleep quality of anger-out and anger-in population based on the frequent pattern-tree (FP-Tree) growing algorithm with data mining. The algorithm of structuring frequent model FP-tree and mining frequent itemsets were designed. The database information scanned was recorded by using FP-Tree growing algorithm through state-trees. The frequent itemsets met minimum support required was generated through reducing the search space of project sets and scanning database only one. The data mining of all factors associated with emotional diseases was actualized. The results showed that factors associated with sleep quality of anger-out and anger-in population were disturbance in respiration, cough or snoring, feeling cold, hot or nightmares. The total time for program analysis was 2 seconds. It was concluded that data mining algorithm based on FP-Tree frequent itemsets can effectively realize the useful information receiving from factors associated with emotional diseases.

Background Oxygen-induced retinal neovascularization is the main pathological basis for many retinal vascular diseases.Research showed that light exposure at night can suppress retinal neovascularization in oxygen-induced retinopathy(OIR),but there were few reports discussing its effect on ROP.Objective This study aimed to observe the effect of light exposure at night on retinal neovascularization in an OIR mouse model.Methods Sixty-four newborn C57 BL/6J mice were randomly divided into four groups,with 16 mice for each group.OIR models were established by rearing the newborn C57BL/6J mice with their mothers in a(75±2)％ oxygen environment from postnatal day 7(P7)to Pl2,and then transferred to room air.In the OIR model group,the environmental illumination level was the same as the normal control group,and the model mice were exposed to 100 lx light at night in the OIR+ light exposure group.In the simple light exposure group,normal mice were reared in room air and were exposed to light at night from P12 to P17.All the mice were sacrificed on P17,and retinal flat mounts were prepared to assess the oxygen-induced changes of retinal vessels using the adenosine diphosphatase(ADPase)histochemical technique.The amount of proliferative neovascularization was quantified by counting the number of endotheliocyte nuclei in new vessels extending from the retinal inner limiting membrane into the vitreous in ocular cross-sections.The expression of the vascular endothelial growth factor(VEGF)protein was detected by immunohistochemistry.Real-time PCR analysis was performed to examine the expression of VEGF mRNA.The rearing and usage of the animals complied with the Statement of ARVO.Results Less free-vascular areas and new blood vessels were seen in the OIR+light exposure group compared with the OIR model group.On day 17 of the mouse life,the number of the endotheliocyte nuclei in new vessels extending from retinal inner limiting membrane were 0.97±0.83,1.00±0.72,38.57±5.01 and 16.92±3.39 in the normal group,simple light exposure group,OIR model group and OIR+light exposure group,respectively,showing significant differences among them(F =78.767,P =0.000).The number of nuclei in the OIR+light exposure group were less than that of the OIR model group(t=20.446,P＜0.01).Immunochemistry showed that the expression of VEGF in retina was weaker in the OIR+light exposure group than the OIR model group.The relative expression values of VEGF mRNA were 1.00±0.00,0.94±0.07,2.08±0.50 and 1.43±0.21 in the normal group,simple light exposure group,OIR model group and OIR+light exposure group,respectively,showing a significant difference (F=11.268,P =0.003),where the VEGF mRNA level in the OIR+light exposure group was lower than that of the OIR model group(t =20.163,P＜0.05).Conclusions Light exposure at night can weaken retinal neovascularization in OIR mice

The combined application of statins that inhibit HMG-CoA reductase and fibrates that activate PPAR-α can produce a better lipid-lowering effect than the simple application, but with stronger adverse reactions at the same time. In the treatment of hyperlipidemia, the combined administration of TCMs and HMG-CoA reductase inhibitor in treating hyperlipidemia shows stable efficacy and less adverse reactions, and provides a new option for the combined application of drugs. In this article, the pharmacophore technology was used to search chemical components of TCMs, trace their source herbs, and determine the potential common TCMs that could activate PPAR-α. Because there is no hyperlipidemia-related medication reference in modern TCM classics, to ensure the high safety and efficacy of all selected TCMs, we selected TCMs that are proved to be combined with statins in the World Traditional/Natural Medicine Patent Database, analyzed corresponding drugs in pharmacophore results based on that, and finally obtained common TCMs that can be applied in PPAR-α and combined with statins. Specifically, the pharmacophore model was based on eight receptor-ligand complexes of PPAR-α. The Receptor-Ligand Pharmacophore Generation module in the DS program was used to build the model, optimize with the Screen Library module, and get the best sub-pharmacophore, which consisted of two hydrogen bond acceptor, three hydrophobic groups and 19 excluded volumes, with the identification effectiveness index value N of 2. 82 and the comprehensive evaluation index CAI value of 1. 84. The model was used to screen the TCMD database, hit 5,235 kinds of chemical components and 1 193 natural animals and plants, and finally determine 62 TCMs. Through patent retrieval, we found 38 TCMs; After comparing with the virtual screening results, we finally got seven TCMs.

OBJECTIVETo establish a new rat model of chronic cyclosporine A nephrotoxicity and explore its features.

METHODSTotally 24 male SD rats were equally randomized divided into 3 groups: sham-adrenalectomized (sham-ADX) group, ADX group and ADX plus cyclosporine A (CsA) group. Rats in ADX and CsA group first underwent adrenalectomy, followed by the administration of placebo or dexamethasone, respectively. Rats in sham-ADX group received sham adrenalectomy and distilled water as control. Six weeks later, all rats were sacrificed and the following indicators were evaluated: urine protein excretion, creatinine clearance, aldosterone level in serum and urine, aldosterone level and its synthase CYP11B2 gene expression in kidney, serum natrium and potassium, urine natrium and potassium excretion, and tubulointerstitial fibrosis by masson trichrome stain.

RESULTSIn ADX and CsA group, serum and urine aldosterone were undetectable on the second post-operative day, with other observations including natriuresis, hyponatremia, decreased urine potassium excretion, and hyperpotassemia, suggesting that adrenals were removed intact and the adrenalectomy was successful. Rats in CsA group showed increased urine protein, decreased creatinine clearance and tubulointerstitial fibrosis, suggesting that a model of chronic CsA nephrotoxicity was successfully established. At the endpoint, serum potassium, serum aldosterone, urine potassium and urine aldosterone excretion partially retrieved. Natrium in serum and urine was not significant different between ADX group/CsA group and sham-ADX group. Local renal aldosterone and its gene expression were remarkably upregulated.

CONCLUSIONSWe successfully established a new rat model of chronic CsA nephrotoxicity by adrenalectomy without low sodium diet. After adrenalectomy, local renal aldosterone in kidney may compensate for circulatory aldosterone deficit to maintain electrolyte balance.

OBJECTIVETo explore effect of interleukin 10 (IL-10) gene-modified bone marrow-derived liver stem cells (BDLSCs) transplantation on hepatic inflammatory response and liver regeneration in rats with liver fibrosis.

METHODS50 female Wistar rats were randomly divided into 4 groups: (1) control group: 10 rats were subcutaneously injected with olive oil for 8 weeks; (2) fibrosis groups: 16 rats were subcutaneously injected with carbon tetrachloride (CCl4) for 8 weeks to induce liver fibrosis; (3) BDLSC group: 12 rats were subcutaneously injected with CCl4 for 8 weeks, and were transplanted with 2 x 10(5) BDLSC at week 4; (4) BDLSC/IL-10 group: 12 rats were subcutaneously injected with CCl4 for 8 weeks, and were transplanted with 2 x 10(5) IL-10 gene-modified BDLSC at week 4. IL-10 and tumor necrosis factor alpha (TNFa) in liver tissues were detected by ELISA. HE stained liver tissues were observed under light microscope. The expression of hepatocyte growth factor (HGF) was quantified by real-time RT-PCR, and the expression of proliferating cell nuclear antigen (PCNA) was determined by immunohistochemistry.

RESULTSThe ratio of IL-10/TNFa in fibrosis group (0.05+/-0.01) was lower than that in control group (0.26+/-0.04) (P < 0.01). Transplantation of untreated BDLSCs did not improve the ratio (P > 0.05), however, transplantation of IL-10 modified BDLSCs improved the ratio significantly (P < 0.01). Severe inflammatory response and fibrosis were observed in fibrosis group. Inflammatory response was alleviated to some extent in the BDLSC group, and the histopathology of BDLSC/IL-10 group was not significantly different from that of the control group. Compared to the control group, the expression of HGF mRNA and PCNA protein was increased in the fibrosis group (P < 0.01). The expression of HGF and PCNA was further increased by BDLSCs or IL-10 modified BDLSCs transplantation. Compared to BDLSCs, IL-10 gene-modified BDLSCs were more potent to induce the expression of HGF and PCNA.

CONCLUSIONTransplantation of IL-10 gene-modified BDLSCs can alleviate hepatic inflammatory response and promote liver regeneration in hepatic fibrosis rats.
