Objective To observe curative effect of Ningdong granules on tourette syndrome (TS) concomitant with sleep disorder in children.Methods Eighty-three cases were diagnosed by diagnosis and statistics of mental-disorder (DSMIV) TS criterion and diagnostic standard of traditional Chinese medicine,and then were divided into 3 groups:tiapride hydrochloride group (n =25),Ningdong granules group (n =30) and tiapride hydrochloride plus Ningdong granules group (n =28).Yale global tic severity scale (YGTSS) and Athens insomnia scale (Athens) were used for rating the clinical efficacy before and after treatment.The enrolled children were treated for a period of three months.Results The therapeutic effective rate of TS in tiapride hydrochloride group,Ningdong granules group and tiapride hydrochloride plus Ningdong granules group was 92.0％,90.0％ and 96.4％,respectively.The therapeutic effective rate of sleep disorder was 84.0％,93.3％ and 96.4％,respectively.Mter treatment,YGTSS and Athens scores were significantly changed in all three groups (P ＜ 0.05).Athens score was significantly different between tiapride hydrochloride plus Ningdong granules group and tiapride hydrochloride group (P ＜ 0.05).The total number of adverse reactions was 16,1 and 8,with significant difference (P ＜ 0.01).Conclusion Curative effect of Ningdong granules is similar to that of tiapride hydrochloride on treating TS,but Ningdong granules is more effective than tiapride hydrochloride on treating sleep disorder with less adverse reactions.Combination therapy of Ningdong granules with tiapride hydrochloride is the better choice for treating TS with sleep disorder,and it can also reduce the incidence of adverse reactions of tiapride hydrochloride.

Objective To develop an in vitro model for cranial suture of neonatal SD rat. Methods The parietal hones with the sagittal suture were removed from SD rats (19-days old) for organ culture. In the experimental group, tensile force 3.92×10~(-3) N (0.4 g) was applied by helical springs, whereas no tension (0 N) was set in control group. These explants were observed under inverted microscope. At the end of the incubation period for 24 hours, general conditions were observed under inverted microscope and histological conditions were observed after hematoxylin and eosin stain. Results Under inverted micro-scope, sutures had no obvious changes in control group, whereas sutures were enlarged gradually in the experimental group. With histological observation, sutures developed normally in control group, but in experimental group, osteohlasts and capillary vessels proliferated actively in the suture. Conclusions In vitro model of cranial suture can be cultured and grown successively.

Objective To investigate micro-inflammatory state and protein-energy wasting (PEW) states in maintenance peritoneal dialysis(MPD) patients,then analysis of the correlation between them.Methods Ninty-six cases of MPD patients in this Hospital were selected from March 2012 to September 2015.The status of nutrition were assessed by Quantitative Subjective and global Assessment(SGA),malnutrition-inflammation score(MIS) and albumin(Alb),micro-inflammatory state was assessed by enzyme-linked immunoassay(ELISA) method serum hypersensitive c-reactive protein (hs-CRP),tumor necrosis factor-α(TNF-α),interleukin-6(IL-6).At the same time,various serological markers like serum Alb,serum total protein(TP),serum prealbumin(PA),hemoglobin(Hb),transferrin(TF),serum creatinine(Scr),urea nitrogen(BUN),cholesterol(Teh) were measured.Results The incidence of PEW in MPD patients was 36.50％,among which 62.86 ％ of them were over 65 years old,57.10％ were over 2 years of dialysis time and 40.00％ with diabetic nephropathy.MPD patients with hs-CRP＞5 mg/L accounted for 58.33％,of which over 65 year old accounted for 42.86％,MPD age longer than 2 years accounted for 60.71％,32.14％ of them with diabetic nephropathy.The proportion of diabetic nephropathy,average age,dialysis duration time,hs-CRP,TNF-α and IL-6 in PEW group were higher than non-PEW group(P＜0.05);BM,TP,Alb,PA,Hb,TCh,MAC and MAMC were lower ban non-PEW group(P＜0.05).Compared with the hs-CRP≤5 mg/L group,average age,the time of dialysis duration,TNF-α,IL-6 were higher and TP,Alb,PA,TF,Hb,the proportion of Kt/V≥1.72 were lower in the hs-CRP＞5 mg/L group.After the correction of age,sex,dialysis ages,it was found that the level of hs-CRP in MPD patients was negatively correlated with the level of Alb,PA,TF,Tch,Scr,TG;The level of IL-6 was negatively correlated with the levels of Alb,PA,TF,Tch,TG.The level of TNF-α in MPD patients showed different degrees of negative correlation with the leves of Alb,PA,TF,TG,Tch(all P＜0.05).Multivariate analysis showed that elderly,the time of dialysis duration,the microinflammatory state,and hypoalbuminemia were the independent risk factors of PEW.Conclusion PEW and micro-inflammatory state are very common in PHD patients.Patients with longer duration of dialysis,elderly or associated with diabetic nephropathy are more likely to suffer PEW and micro-inflammatory.Elderly,the time of dialysis duration,microinflammatory state,hypoalbuminemia are the independent risk factors of PEW.

Objective To demonstrate the relationship between Cdc20 mutation and the promotion of colon cancer via Cdc20loxp/+ APCmin/+ villin-cre+/-compound mutant mice.Methods Cdc20loxp/+ APCmin/+ villin-cre+/-compound mutant mice and APCmin/+ mutant mice were generated by mice mating strategy.The colon tumors of two group mice were compared by phenotypic analysis and histology analysis.Results Phenotypic analysis showed that the number of tumors in Cdc20loxp/+ APCmin/+ villin-cre+/-compound mutant mice group and APCmin/+ mutant mice group was 1.2±0.5 and 1.6±0.5, respectively (t =0.215, P =0.588), and the maximum diameter of tumors was (2.7±0.3) cm and (2.5±0.2) cm, respectively (t =0.568, P =0.575).Pathologic type of Cdc20loxp/+ APCmin/+ villin-cre+/-compound mutant mice was adenocarcinoma, while that of APCmin/+ mice was tubular adenoma.Conclusion Cdc20 carrying a null allele can accelerate the promotion of colon cancer in APCmin/+ mice without influence on the tumor number and size.

Objective According to the fine artery anatomy of the lower lip, we developed an innovative partial-thickness myocutaneous flap based on the vascular network of the submucosal and subcutaneous layers of the lower lip.We attempted to treat the secondary bilateral cleft lip deformities using this innovative cross-lip flap.Methods From July 2009 to June 2015, this new technique was used in 98 patients with secondary bilateral cleft lip deformities.The central defects usually occurred in these patients.The defects were reconstructed partially or completely according to the severities of the defects.The operative procedures were as follows: The split flap was elevated from the posterior portion of the oris orbicularis muscle after the inferior labial arteries were divided.Then the partial-thickness flap was rotated 180 degrees horizontally and inverted 180 degrees upward to the upper lip defect.Results All 98 musculomucosal pedicle flaps were viable.The upper lips were reconstructed according to the severities.Conclusions This myocutaneous cross-lip flap with musculomucosal-pedicle has a more reliable blood supply, better flexibility and plasticity.It is an effective method for aesthetic reconstruction for the secondary bilateral cleft lip deformities.

In this study, we investigated the effect of Cigu Xiaozhi formula on HSC-T6 activity in hypoxic microenvironment based on network pharmacology and computer-aided drug design, and predicted and verified its possible targets and related signaling pathways. The potential active components and targets of Cigu Xiaozhi formula were screened by searching Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), Encyclopaedia of Traditional Chinese Medicine (ETCM) and Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine (BATMAN-TCM) databases, and the liver fibrosis related targets retrieved from Gene Cards and Pharm GK database were integrated to obtain the potential targets of Cigu Xiaozhi formula in the treatment of liver fibrosis. GO enrichment analysis and KEGG signaling pathway enrichment analysis were performed on Omic Share platform, and Cytoscape software was used to construct the "potential active ingredient-key target-pathway" network. The active components and target proteins were subjected to molecular docking analysis by Auto Dock software. According to the results of molecular dynamics simulation and binding free energy calculation, the top 5 active components with degree were scored. The active components stigmasterol and β-sitosterol were subjected to molecular docking. CoCl₂ was used to induce HSC-T6 cells to construct hypoxia model in vitro. The cell viability was detected by CCK-8 assay, and the optimal time and concentration of hypoxia model of HSC-T6 cells was determined to be 100 µmol·L^-1 CoCl₂ for 24 h. Under hypoxia condition, HSC-T6 cells were activated, the wound healing rate was significantly increased, and the fluorescence signal of activation marker protein α-smooth muscle actin (α-SMA) was significantly enhanced. However, 6% drug-containing serum could inhibit the activation of HSC-T6 cells, and the wound healing rate was significantly decreased, and the fluorescence signal of α-SMA was significantly weakened. Further studies showed that the expressions of hypoxia-inducible factor-1α (HIF-1α), α-SMA and key proteins of Hedgehog (Hh) signaling pathway in HSC-T6 cells were up-regulated under hypoxia, while the expressions of HIF-1α, α-SMA, Patched-1 (Ptch-1) and glioma related oncogene homology-1 (Gli-1) were down-regulated in 6% drug-containing serum group, the YC-1 group and the cyclopamine group. These results indicated that HIF-1α and Hh signaling pathways were involved in the activation of HSC-T6 cells, and the traditional Chinese medicine Cigu Xiaozhi formula could inhibit the activation of HSC-T6 cells, and the mechanism may be related to the inhibition of HIF-1α expression and the blocking of Hh signaling pathway. In conclusion, Cigu Xiaozhi formula can inhibit the activation of HSC-T6 cells by directly acting on HIF-1α and Hh signaling pathway, and exert an anti-hepatic fibrosis effect. The animal experimental protocol has been reviewed and approved by Laboratory Animal Ethics Committee of Gansu University of Chinese Medicine, in compliance with the Institutional Animal Care Guidelines.

Background Protease activated receptor-2 is cleaved and activated by trypsin or mast cell tryptase and may play an important role in inflammation. However, it is unknown whetehr PAR-2 can mediate tryptase-induced inflammatory reaction. This study was conduct to investigate wheter PAR-2 could be the activated by mast cell tryptase and medicated the tryptase induced interleukin-8 expression in endothelial cells.Methods Protease activated receptor-2 expression was found in endothelial cell lines ECV304 cell by reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting. Interleukin-8 stimulated by purified human mast cell tryptase was determined by RT-PCR and enzyme linked immunosorbent assay (ELISA). Data were analysed by the S-N-K one-way ANOVA test.Results The present study shows that mRNA and protein of protease activated receptor-2 could be expressed in ECV304 cells, and tryptase upregulated the expression levels of both interleukin-8 mRNA and protein. The increased expression of interleukin-8 was inhibited by an antiprotease activated receptor-2 monoclonal antibody, SAM11. An additional band was observed by Western blotting after the incubation of ECV304 cells with tryptase for 2 hours, which suggested that protease activated receptor-2 was activated. Conclusion Protease activated receptor-2 can mediate the mast cell tryptase stimulated expression of interleukin-8 in ECV304 cell.

OBJECTIVEEstrogens play an important role in intrinsic skin aging. The associated changes in global gene expression are poorly understood.

METHODSWe used the Illumina microarray platform to obtain comprehensive gene expression profiles in female Chinese Han skin, and confirmed the data by quantitative real-time PCR (Q-RT-PCR).

RESULTSWe found 244 genes significantly related to estrogen-associated intrinsic skin aging, and some of these genes were confirmed by Q-RT-PCR. We also performed functional analysis by both Gene Ontology annotation and enrichment of the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways database. The functional analysis revealed 11 biological pathways (including the KEGG pathways, the mitogen-activated protein kinase signaling pathway and metabolic pathways), that were associated with multiple cellular functions which may be involved in intrinsic skin aging.

CONCLUSIONThis study suggests that estrogen-associated intrinsic skin aging is a complicated biological process involving many genes and pathways.
