Objective To analyze of the relationship between level of anxiety and depression before surgery and anus exhausting time for patients after gynecological abdominal surgery.Methods A descriptive study was conducted with a survey of 100 cases of patients with gynecological abdominal surgery where the level of anxiety and depression before surgery and post-anus exhausting time were analyzed to explore the correlation between them.Results In the 88 valid questionnaires,the incidences of stress and anxiety before surgery were respectively 38.64％(34/84) and 19.32％(17/88) and the average anus exhausting time after surgery was (44.55 ± 13.90) hours;the anus exhausting time of anxious patients was significantly longer than that of non-anxious patients [(48.35±12.84) hours vs.(42.50±14.13) hours,t=-2.12,P＜0.05] and bivariate Logistic regression analysis suggested that preoperative level of anxiety had a significant effect on anus exhausting time after surgery.Conclusions Stress,anxiety and other negative emotions can affect anus exhausting time after surgery and level of anxiety could be used as one predictor of the delay of anus exhausting time after surgery.

Objective To investigate the effects and anti-atherosclerotic mechanism of rosiglitazone on the expression of ATP-binding cassette transporter A1 (ABCA1) and reverse cholesterol transport (RCT) in atherosclerotic rabbits. Methods Twelve rabbits were randomly divided into two groups (6 each): control group (only high cholesterol diet for 6 weeks), rosiglitazone group [high cholesterol diet plus rosiglitazone 0.5mg/(kg?d) for 6 weeks]. ABCA1 expression and [3H] cholesterol efflux rates were evaluated by flow cytometry and liquid scintillation spectrometry, respectively. Enzymatic methods were used to assay serum lipids levels and cholesterol contents in tissues, and the atherosclerotic area of aorta was calculated by professional image analysis software. Results For the rabbits of both control and rosiglitazone group, the serum levels of high-density lipoprotein cholesterol (HDL-C), non-high-density lipoprotein cholesterol (NHDL-C) and apolipoprotein A1 (apoA1) significantly went up when they took their cholesterol rich diet for 6 weeks (P0.05). Compared with control group, the ABCA1 expressions in monocytes, peritoneal macrophages, adipocytes and hepatocytes, as well as the cholesterol efflux rates in peritoneal macrophages, adipocytes and hepatocytes increased significantly (P

Purpose To explore the feasibility of double low dose technology in multi-slice head and neck CT angiography, so to reduce contrast agent as well as reduce radiation dose. In that way, the hazards of radiation and the risk of contrast induced nephropathy would be reduced. Materials and Methods Fifty-one patients took double low proposal were recruited as double low group. Another 51 patients who took conventional proposal were recruited as conventional group. The scanning parameters of double low group were 100 kV, 300 mA, 0.7 ml/kg iodinated contrast agent and which of conventional group were 120 kV, 350 mA, 1.0 ml/kg iodinated contrast agent. The CT value of the vessels and image noise were measured. Signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), subjective image quality score, radiation dose and iodine load between the two groups were compared. Results The volume CT dose index (CTDIvol) of the double low group and the conventional group were 18.00 mGy and 33.86 mGy, respectively. And the effective dose were 3.85 mSv/(mGy · cm) and 7.25 mSv/(mGy · cm), respectively. The iodine loads were 224 mgI/kg and 320 mgI/kg, respectively. SNR and CNR at the aortic arch were higher in double low group than in conventional group, but which was not statistic significant (t=-1.572 and -1.783, P>0.05). The SNR and CNR of bilateral carotid arteries, internal carotid arteries, and middle cerebral arteries had no statistic significance between the two groups (t=0.341-1.739, P>0.05). The subjective image quality scores of double low group and conventional group were (3.69±0.47) scores and (3.70±0.46) scores, which showed no statistic difference (Z= - 0.213, P>0.05). Conclusion Approving images of multi-slice head and neck CT angiography can be obtained by using double low dose technology without adaptive statistical iterative reconstruction.

Tanshinones are the bioactive components of the Chinese medicinal herb Salvia miltiorrhiza, while its biosynthetic pathway remains to be characterized. Rapid identification and characterization of the genes correlated to tanshinones biosynthesis is very important. As one of the intermediates of tanshinones biosynthesis, the ferruginol content is relative low in both root and engineered bacteria. It is urgent to construct an efficient system for conversion of miltiradiene to ferruginol to obtain large amount of ferruginol as the substrates for further identifying other downstream genes involved in tanshinones biosynthesis. In this study, we constructed the whole-cell yeast biocatalysts co-expressing miltiradiene oxidase CYP76AH1 and cytochrome P450 reductases (SmCPR1) from Salvia miltiorrhiza, and then characterized it with RT-PCR. After permeabilization, the yeast whole-cell could catalyze turnover of miltiradiene to ferruginol efficiently through single-step biotransformation with a conversion efficiency up to 69.9%. The yeast whole-cell biocatalyst described here not only provide an efficient platform for producing ferruginol in recombinant yeast but also an alternative strategy for identifying other CYP genes involved in tanshinones biosynthesis.

Objective To investigate the expression and distribution of plasmacytoid dendritic cells(pDC) in peripheral blood and renal tissues in children with Henoch-SchSnlein purpura(HSP),and explore the role of pDCs in the pathogenesis of Henoch-Schtnlein purpura nephritis(HSPN).Methods Among the 40 children with HSP,28 cases were in the active phase(renal biopsy performed in 8 cases of them) and the other 12 in remission phase.Peripheral blood mononuclear cells were isolated,and the expression of pDC was detected by flow cytometry.The normal control group was established (n =15).Total RNA of peripheral blood was extracted and transcripted into cDNA.Sybr green dye based real-time quantitative PCR method was used to compare the expression(indicated as 2-△Ct value) of CXC motif chemokine 10 (CXCL10),CC chemokine ligand 5 (CCL5),chemokine CXC subfamily receptor 3 (CXCR3),CC chemokine receptor 5 (CCR5) in children with HSP and those in the controls.Immunohistochemistry labeling technique was used to detect the distribution of pDC in renal tissues from renal biopsy,and the normal controls were established (n =3).Results The expression percentage of pDC in peripheral blood in active phase was 0.051 ± 0.039,significantly lower than those in remission phase (0.181 ± 0.082) and the normal controls (0.166 ± 0.079) (P ＜ 0.000 1).Chemokines genes CXCL10 and CCL5 were overexpressed in peripheral blood ceils of acute phase HSP children,but chemokine receptors CXCR3,CCR5 were lowly expressed compared with normal controls.There was almost no expression of pDC in the normal control renal tissues,while pDC was infiltrated in glomeruli of HSPN children.Conclusions The number of pDC and chemokines' expression in peripheral blood is abnormal,and the pathogenesis of nephritis may be involved with the pDC in peripheral blood to migrate to the renal tissues.

Objective The current study aimed to evaluate whether the induction of macrophage inflammatory cytokines by Ox-LDL is related to the expression of ABCA1 pathway. Methods After THP1/PMA macrophages were transfected with ABCA1 antisense oligonucleotides (100nmol/L) followed by treatment with Ox-LDL (30mg/L), the expressions of ABCA1, ICAM-1 and MCP-1 mRNA and protein were determined by real-time fluorescent quantitative RT-PCR, Western blot or ELISA. Results Ox-LDL induced expressions of ABCA1, ICAM-1, and MCP-1 at both mRNA and protein levels from THP1/PMA macrophages. Transfection with ABCA1 antisense oligonucleotides reduced ABCA1 mRNA levels after 3 and 6 hours and protein levels after 12 and 24 hours. The expression of ICAM-1 and MCP-1 induced by Ox-LDL was also decreased after inhibition of ABCA1 protein expression by ABCA1 antisense oligonucleotide decreased. Conclusion The induction of macrophage inflammatory cytokines by Ox-LDL is partially dependent on expression of ABCA1. Our studies disclose new functions of ABCA1 in macrophages.

Objective To investigate the role of autophagy in radiation-induced death response of human nasopharyngeal carcinoma cells.Methods MTT method was used to detect cell viability of CNE-2 cells in different time after irradiation.Clonogenic survival assay was used to evaluate the effect of autophagy inhibitor (chloroquine phosphate) and autophagy inductor (rapamycin) on radiosensitivity of nasopharyngeal carcinoma cells.Cell apoptosis was assessed by flow cytometry.The expressions of LC3 and P62 were measured with Western blot.Cell ultrastructural analysis was performed under an electron microscope.Results Irradiation with 10 Gy induced a massive accumulation of autophagosomes accompanied with up-regulation of LC3-Ⅱ expression in CNE-2 cells.Compared with radiation alone,chloroquine phosphate (CDP) enhanced radiosensitivity significantly by decreasing cell viability (F =25.88,P ＜ 0.05),autophagic ratio (F =105.15,P ＜ 0.05),and LC3-Ⅱ protein level(F =231.68,P ＜0.05),while up-regulating the expression of P62 (F =117.52,P ＜ 0.05).Inhibition of autophagy increased radiation-induced apoptosis (F =143.72,P ＜ 0.05).Rapamycin (RAPA) also significantly decreased cell viability,but increased autophagic ratio and LC3-Ⅱ protein level while down-regulated the expression of P62.Induction of autophagy increased radiation-induced apoptosis(F =167.32,P ＜ 0.05).Conclusions Blockage of autophagy with CDP could enhance radiosensitivity in human nasopharyngeal carcinoma cells,suggesting that inhibition of autophagy could be used as an adjuvant treatment to nasopharyngeal carcinoma.
