Objective To investigate the photo-protective mechanisms of hydroxychloroquine and epigallocatechin gallate (EGCG) on HaCaT cells damaged from UVB irradiation. Methods Subconfluent HaCaT cells were irradiated with different doses of UVB irradiation and treated with the above listed agents. The mRNA expression levels of p53, p21, c-fos and GADPH genes were evaluated by reverse transcription-polymerase chain reaction (RT-PCR). Results UVB irradiation induced mRNA expression of p53, p21 and c-fos in cultured HaCaT cells, which were alleviated by hydroxychloroquine and EGCG treatment in UVB irradiation group. Conclusions The photo-protective effects of hydroxychloroquine and EGCG on HaCaT cells by UVB irradiation might be related to inhibition of the expression of p53,p21 and c-fos genes.

Objective To compare genomic expression differences between androgenic complete hydatidiform mole (AnCHM) and normal first trimester villi with similar gestation weeks,and search for potential adjuvant diagnostic molecular markers.Methods Short tandem repeat (STR) detection was used to identify AnCHM,human oligonucleotide array U133 Plus 2.0 was used to measure genomic expression differences between AnCHM and normal villi,and quantitative fluorescent RT-PCR was used to verify array of several genes.Results Nine of 11 histologically diagnosed complete hydatidiform moles were found to be AnCHM by means of STR,and the other 2 were biparental complete hydatidifonn mole (BiCHM). Compared with villi,oligonueleotide array showed 279 genes (0.72%,279/38 500) were over expressed and 1710 genes (4.44%,1710/38 500) under expressed in AnCHM.Bioinformatics analysis found that differentially expressed genes were involved in multiple biological processes and pathways.Changes of imprinting genes,growth hormone genes and chorionie somatomammotropin hormone genes were especially remarkable.Conclusions Pathogenesis of AnCHM is a complex process involving multiple genes and pathways.Altered expression of imprint genes may play important roles in the process.

BACKGROUNDNon-small cell lung cancer (NSCLC) is the leading cause of cancer mortality worldwide. Platelet activation may play an important role in pathologic progress in lung cancer. In this study, we aimed to clarify the influence of activated platelets on lung cancer generation and growth, and the relationship among these functional and ultrastructural changes of platelets and the severity of pathogenetic condition in these patients with NSCLC.

METHODSOne hundred and thirty-six cases of patients with pathologically confirmed NSCLC were included in this study. Fifty-four healthy people were enrolled as controls. The change of ultra microstructure and activity of blood platelets were observed under the transmission and scanning electron microscope. Simultaneous determination of plasma granule membrane protein 140 (GMP-140) was made.

RESULTSTransmission electron microscopy showed remarkable changes of ultra microstructure of platelets in patients with NSCLC, including swelling, increase of a-granules, vesicles, and glycogenosome. Scanning electron microscopy showed many more surface processes and wrinkles on platelets in patients with NSCLC. The reference plasma levels of GMP-140 of healthy controls were (18.2 +/- 2.7) microg/L. The plasma levels of GMP-140 in patients with NSCLC were (47.8 +/- 12.3) microg/L, which were much higher than those of the controls. There was a medium positive correlation between plasma levels of GMP-140 and amount of a-granules (r = 0.514, P < 0.01) and a high positive correlation between plasma levels of GMP-140 and area of platelet (r = 0.84, P < 0.01) in patients with NSCLC. The Kaplan-Meier survival curve analysis showed significant shift to the left in patients with NSCLC whose a-granules per platelet were 19 or more compared to those 18 or less (Log rank statistic, chi(2) = 17.38, P < 0.01).

CONCLUSIONSThere are significant activated changes of ultra microstructure and increased activity of blood platelets in patients with NSCLC. These activated platelets may play an important role in the generation and growth of lung cancer. These changes can be used as a diagnostic index of severity, progression, and prognosis of NSCLC.

Objective To study the effect of ventilator cluster nursing in mechanically ventilated patients in Craniocerebral Department.Methods Totals of 60 cases of mechanically ventilated patients admitted during January 2010 to July 2011 in Craniocerebral Department wards were the experimental group,which received ventilator cluster nursing,including raising bed 30-45 °,prevention of peptic ulcer,trying to stop sedatives everyday,prevention of deep vein thrombosis,oral care,attraction of subglottic secretions and hand hygiene.A total of 58 cases of mechanically ventilated patients from June 2008 to December 2009 in the same department were the control group,receiving conventional methods of nursing.Incidence,duration of mechanical ventilation and mortality of ventilator-associated pneumonia (VAP) in two groups were compared.Results The incidence,duration of mechanical ventilation and mortality of VAP were respectively 40.0％,(189.7 ± 64.5) h and 25.0％ in the experimental group,72.4％,(331.3 ± 86.7) h and 51.7％ in the control group,and the differences were statistically significant (x2/t =12.571,10.089,8.928,respectively; P ＜0.05).Conclusions Ventilator cluster nursing can reduce the incidence and mortality of VAP,as well as shorten the duration of mechanical ventilation in mechanically ventilated patients in Craniocerebral Department.

AIM:To explore the effects of CD38 on lysosome reformation and cholesterol efflux in macro-phages.METHODS:Bone marrow-derived macrophages from low-density lipoprotein(LDL)receptor knockout(LDLr-/-)mice were cultured as cell model.Live cell imaging system was applied to evaluate the effect of nicotinic acid adenine di-nucleotide phosphate(NAADP)on lysosome number.ELISA was conducted to measure NAADP level in macrophages.After the cells were treated with nicotinic acid(NA),RT-qPCR was conducted to detect CD38 mRNA expression,and Western blot was conducted to observe CD38 protein expression and phosphorylated transcription factor EB(TFEB)level.Laser scanning confocal microscopy was applied to evaluate the influence of CD38/NAADP signaling on lysosome number and cholesterol egression.RESULTS:NAADP remarkably increased lysosome number(P<0.05),and this effect was significantly inhibited by NAADP antagonist NED-19,Ca2+ chelator BAPTA,and calcineurin inhibitor CsA(P<0.05).CD38 markedly enhanced NAADP synthesis in macrophages(P<0.05).NAADP synthetic substrate NA prominently ele-vated the expression of CD38 mRNA and protein(P<0.05).NA significantly decreased the phosphorylated TFEB level;this effect was also attenuated by NED-19,BAPTA and CsA(P<0.05).Disrupting CD38/NAADP signaling pathway markedly inhibited NA-induced enhancement of lysosome number,lysosomal free cholesterol and cytosol cholesterol ester efflux in macrophages(P<0.05).NA-induced enhancement of lysosome number,lysosomal free cholesterol and cytosol cholesterol ester efflux abolished in LDLr/CD38 DKO macrophages(P<0.05),whereas these effects induced by NA were recovered after CD38 gene rescue.CONCLUSION:CD38 triggers lysosome reformation via TFEB and consequently pro-motes the efflux of lysosomal free cholesterol and cytosol cholesterol ester.
