To study the effects of Qingdai compound on proliferation and apoptosis of K562 cells, as well as the expression of bcr/abl and JWA mRNA, K562 cells were treated in culture with different concentrations of Qingdai compound (2.5, 5, 7.5, 10 and 20 mg/ml) and harvested at 24 hours. Then morphological changes were observed by light microscopy (LM); expressions of bcr/abl and JWA were detected with semi-quantitative RT-PCR. The results showed that morphological changes were observed as the increment of the Qingdai compound concentration. Inhibition effects on proliferation and apoptosis in K562 cells were seen. A concentration-dependent decreases were found in bcr-abl and JWA mRNA expression of K562 cells. Qingdai compound partially inhibited proliferation and induced apoptosis of K562 cells. Expressions of both bcr/abl and JWA, which took part in cell proliferation and apoptosis, were down-regulated in a dose dependent manner. In conclusion, Qingdai compound can partially inhibit the expressions of bcr/abl and JWA genes in K562 cells, and the clinical effect of Qingdai compound on CML may be associated with apoptosis of leukemic cells.

The study was aimed to explore the role of gene JWA, a novel retinoic acid responsible and cytoskeleton associate gene, in regulating committed differentiation of HL-60 cell and the molecular mechanism in the course of differentiation and apoptosis of leukemic cells. By using FCM, the changes of CD13, CD14, CD15, CD11b and cell cycles were detected in HL-60 cells treated with ATRA (10(-6) mol/L), Ara-C (10 ng/ml) and TPA (10(-8) mol/L) respectively. The samples were determined by semi-quantitative reverse transcript-polymerase chain reaction (RT-PCR) and Western blot for the expression of JWA, Bcl-2, HSP27 and HSP70 at day 0, 2, 4, 6, 8. The results showed that HL-60 cells committedly differentiated into granulocyte-, monocyte-, macrophage-like cells. As a result, JWA was up-regulated in a time-dependent manner, while Bcl-2 was down- regulated at the same time. In ATRA and TPA group, the change of HSP70 had positive correlation with JWA, and negative correlation with Bcl-2. The expression of HSP27 was not detected. Contrast to the cells from APL patient, the expression of JWA need not be activated by ATRA in advance. In this study, we also exposed HL-60 cells in higher dose of Ara-C (20 ng/ml), and JWA expression underwent opposite trend comparing with in lower dose of Ara-C (10 ng/ml). It is concluded that JWA may play double important roles in regulating ATRA and TPA-induced differentiation and apoptosis in leukemic cells. The JWA expression had a negative correlation between induction and cytotoxic response. The difference of JWA expressions between HL-60 cell and ANLL patient cells would be involved in different leukemia pathogenesis.

Objective To investigate the clinical features,diagnosis,treatment,and prognosis of patients with liver injury caused by Periploca forrestii Schltr.Methods A retrospective analysis was performed for the general data,clinical manifestations,and laboratory examinations of 22 patients who were diagnosed with liver injury caused by Periploca forrestii Schltr.from November 2014 to December 2015,and their clinical type was determined according to the classification criteria of drug-induced liver injury recommended by the Council for Intemational Organizations of Medical Sciences.Results There were 12 female and 10 male patients.The mean medication time ranged from 1 week to 2 months,and as for biochemical markers,there were mainly abnormalities in alanine aminotransferase (ALT),aspartate aminotransferase (AST),total bilirubin (TBil),alkaline phosphatase (ALP),and gamma-glutamyl transpeptidase (GGT).ALT and AST increased in all the patients,with mean levels of 676.68±481.11 U/L and 527.36±361.14 U/L,respectively;TBil increased to a mean level of 170.26±147.30 μmol/L in 19 patients;ALP increased to a mean level of 135.61±59.26 U/L in 13 patients;GGT increased to a mean level of 195.65±138.48 U/L in 20 patients.As for clinical typing,18 patients had liver cell injury,none had cholestasis,3 had a mixed type,and 1 had an unclassified type.One patient died and all the other patients fully recovered.Conclusion Periploca forrestii Schltr.had complex constituents,and liver injury caused by this drug is mainly liver cell injury.The pathogenesis of liver injury caused by Periploca forrestii Schltr.is presumed to be related to patients' idiosyncratic reaction to its constituents.

OBJECTIVETo evaluate the overall diet quality and diet model of labor workers in Shenzhen using Chinese Diet Balance Index (DBI).

METHODSIn May 2009, 14 canteens from Baoan, Longgang and Nanshan districts were selected by stratified random sampling and 60 workers were randomly selected from each canteen by using random number method. Diet measurements were carried out among the 840 labor workers. Diet quality was evaluated by using DBI scoring and evaluating system.

RESULTSThe median values of labor workers' food intakes of cereal and meat & poultry were 483.8 and 121.7 g/d, which were more than the recommended amounts of their intakes of Chinese residents (cereal: 250 - 400 g/d, meat & poultry: 50 -70 g/d). The median values of the labor workers' intakes of fruit, dairy and eggs were 37.3, 20.6 and 23.5 g/d,which were less than recommended amounts in fruits (200 - 400 g/d), dairy (300 g/d) and eggs (25 - 50 g/d). The DBI-HBS scores of males and females in Shenzhen migrant workers were 24.4 +/- 6.1 and 22.6 +/- 6.3, respectively with a statistically significant difference (t = 4.21, P < 0.01). DBI-HBS scores of < 20 age group, 20 - 29 age group, 30 - 39 age group and > or = 40 age group in labor workers were 12.7 +/- 5.9, 11.3 +/- 6.3, 12.8 +/- 6.4 and 11.2 +/- 5.6 respectively (F = 3.67, P = 0.01). There were 7 dietary patterns among labor workers in this survey. Nearly 8.2% (68/830) of them belonged to Pattern A. Pattern B and E were the main dietary patterns, which accounted for 37.3% (310/830) and 31.0% (257/830) of the total population.

CONCLUSIONDBI can describe and evaluate the overall dietary quality and the major problem of the dietary patterns in labor workers. It is necessary to strength nutritional education to increase the intake of fruits, milk and eggs to improve nutritional status in labor workers in Shenzhen.

OBJECTIVETo investigate the effects of mobile phone 1800 MHz electromagnetic fields (EMF) on the surface markers and the functions of human dendritic cells (DC).

METHODSHuman DCs were exposed to intermittent 5 min on/10 min off EMF with specific absorption rates (SAR) 4 W/kg for 0 h, 1 h, 12 h or 24 h, respectively. FACS analysis was used to detect the positive percentage of DC surface markers including HLA-DR and co-stimulatory molecules such as CD80, CD86, CD40 and CD11c. CCK-8 kit was adopted to examine the function of allo-mixed lymphocyte reaction (allo-MLR) of DC, and enzyme linked immunosorbent assay (ELISA) to identify the levels of IL-12p70 and TNF-alpha secreted by DC.

RESULTCompared with the sham radiation group, after exposure to the electromagnetic fields for 1 h, 12 h, or 24 h, HLA-DR, CD80,CD86 and CD40 were all declined except CD11c. The ability of DC allo-MLR in each exposure group was decreased significantly (P<0.05), especially in the 24 h exposure group. However, the secreted levels of IL-12p70 and TNF-alpha of DC in each exposure group remained no changed.

CONCLUSIONThe study showed that EMF exposure could down-regulate the surface molecules and stimulation ability of human DC.
