Objective To study the protective effect of resveratrol on endothelial cells injury induced by oxidized low-density lipoprotein (oxLDL) and its protective mechanism. Methods The injured model was established by endothelial cell treated with oxLDL. In the experiment, endothelial cell were cultured in vitro and divided into seven groups which were: control group; solvent (DMSO) group, oxLDL group, quercetin plus oxLDL group, Reseveratrol-L (0.5 mol/L), M(5 mol/L), H(50 mol/L) plus oxLDL group respectively. Endothelial cells were incubated with 200?g/ml oxLDL for 18 hours in the absence or presence of various concentrations of resveratrol and quercetin. The apoptotic index was detected by flow cytometric. Meanwhile, the content of Malondialdehyde (MDA), and the activity of SOD, GSHPX in the culture medium and homogenate of endothelial cells were measured. Results Incubation of endothelial cells with oxLDL for 18 h elicited a significant increase in the percent of apoptotic endothelial cells, in control group, the percent of apoptotic cells is 7.6?0.6, however in oxLDL group, it increased to 41.4?2.3, furthermore, oxLDL induced the increase of the contents of MDA, and accompanied by the decrease in the activity of SOD, GSHPX in the endothelial cells, the difference of was significant as compared with control group. Pretreatment of resveratrol with 0.5～50 mol/L decreased these oxLDL-induced changes, in Reseveratrol with 50 mol/L group, the percent of apoptotic cells decreased to 13.0?1.5, the difference of was significant as compared with oxLDL group (P

Objectives To investigate the clinical characteristics and diagnosis of Gaucher disease. Methods The clini-cal features, enzyme activities and genetypes of an infant with Gaucher disease II were analyzed. Results The main clinical manifestations of the infant included hepatosplenomegaly, ocular dyscinesia and mental retardation. Gaucher′s cells could be seen in the bone marrow aspirates. Glucocerebrosidase activity was low (0.3 nmol/g/min). Serum chitotriosidase activity was high (87317 nmol/L/min). GBA mutations were M85T (c.371T>C) and R120W (c.475C>T).

Objective To investigate the detection of human bocavirus (HBoV) in children with acute respiratory infection and to explore the relationship between viral load and clinical characteristics of acute respiratory infection in children.Methods A total of 4 501 nasopharyngeal secretion samples were collected from hospitalized children with acute respiratory infection from January 2013 to June 2013.HBoV-positive children were divided into simple infection group and mixed infection group.Children with HBoV DNA≥1 × 104 copy/mL were categorized into high viral load group,while those with HBoV DNA ＜1 × 104 copy/mL were categorized into low viral load group.HBoV was determined by fluorescence quantitative polymerase chain reaction (PCR).Respiratory syncytial virus (RSV),influenza virus (Inf)-A,Inf-B,parainfluenza virus (Pinf)-Ⅰ 、Pinf-Ⅱ 、Pinf-Ⅲ and adeno virus antigen were detected by direct antigen-specific immunofluorescence assays.Mycoplasm Pnuemonia was detected by real-time fluorescence quantitative PCR.Serum mycoplasma antibodies were detected by enzyme-linked immunosorbent assay (ELISA).Bacteria was detected by sputum culture.Over the same period,23 children undergoing elective inguinal hernia operation with no respiratory infection or fever were considered as control group.The percentage of peripheral blood T lymphocyte subsets were tested by flow cytometry.Inter-group differences were compared using Chi-square test or Fisher exact test.Viral loads were compared using Mann-Whitney test.Results Two hundred and twenty-two HBoV-positive cases were detected with a positive rate of 5.41％ (222/4 105),33.33％ (74/222) of which were with high viral load and 66.67％ (148/222) were with low viral load.There was a high incidence in the age group of 1-2 years.The simple HBoV infection accounted for 24.32％,including 26 cases with high viral load and 28 cases with low viral load.Wheezing was more common in patients with high viral load than those with low viral load,and the difference was statistically significant (88.46 ％ vs 42.86 ％,x2 =12.295,P=0.001).Among the 222 HBoV-positive cases,the median viral load of HBoV in simple infection group was 3.86 × 103 copy/mL,and 1.0× 103 copy/mL in mixed infection group.The difference of the viral load between these two groups was statistically significant (Z =2.906,P =0.004).Mycoplasma and Streptococcus pneumonia were most commonly detected in the 168 patients with mixed infection.Percentages of CD3+ and CD3+/CD8+ subsets were significantly lower in HBoV simple infection group and mixed infection group,compared to control group (both P＜0.05).However,percentages of CD3 /CD19+,CD19+/ CD23+ subsets were significantly higher in HBoV simple infection group and mixed infection group,compared to control group (both P＜0.05).Conclusions HBoV is one of the pathogens causing acute respiratory tract infection in children,which lead to cellular immunity dysfunction in children.Moreover,children with higher HBoV load are more likely to develop wheezing.Co-infection with other pathogens should be considered in children with low HBoV load.

Objective To investigate the HBV- positive pregnant women about the knowledge of the route of hepatitis B transmission, hepatitis B hazards, health care during pregnancy, announcements of child- care to explore targeted and effective health education model with self- designed question-naires. Methods Nurses in obstetrics department carried out this questionnaire investigation in the outpa-tients of HBV- positive pregnant women, after that the results underwent statistic analysis. Results The overall knowledge of HBV- positive pregnant women in announcements of child- care, health care during pregnancy and hepatitis B hazards was not very well, and the announcements of child- care was the lowest, followed by health care during pregnancy and hepatitis B hazards. The route of hepatitis B transmission was better, but still not satisfactory. The education should highlight these areas. Well- educated women were better than those who lack education. The age between 20 to 30 years old was better. Conclusions The HBV-positive pregnant women is lack of heath knowledge, so we should gave health intervention in a multi- level, multi- stage standardized and a variety of ways.

Objective To explore the role of 14-3-3σ in cell cycle arrest,proliferation inhibition of HaCaT cells after UVB exposure.Methods Crystal violet assay was used to determine the viable density of HaCaT,HaCaTKD cells after being irradiated with UVB of different doses (10,20,30,40,50,60 and 80 mJ/cm2) for 48 h.After HaCaT and HaCaTKD being treated with 30 mJ/cm2irradiation,cell growth and cell cycle distribution were detected by CCK-8 assay and PI staining combined with flow cytometry,respectively.Western blot was used to evaluate the protein expression of 14-3-3σ,Cdc2,Cdc25c and Cyclin B1.Results After 48 h,the survival rate of both HaCaT and HaCaTKD decreased in a dosedependent manner.Especially,HaCaTKD cells had drastically low proliferation rate compared with normal HaCaT at 10 mJ/cm2 (t =8.83-49.63,P ＜ 0.05).The proliferation rate of HaCaTKD cells was significantly lower than that of HaCaT cells (F =32.89,P ＜ 0.05).After treatment with 30 mJ/cm2 UV irradiation,the ability of proliferation in normal HaCaT cells was recovered after 24 h while there was no proliferation in HaCaTKD cells within 72 h after the same treatment.The distribution of cell cycle has little change in HaCaTKD (P ＞ 0.05).UVB treatment led to cell cycle arrest from 6 to 18 h in HaCaT cells(t =7.41,9.22,9.16,P ＜0.05)while no cell cycle arrest could be observed in the HaCaTKID cell.Western blot detection indicated that the expression of 14-3-3σ in HaCaT cells was upregulated(t =5.42-9.57,P ＜0.05)while the Cdc25c and Cyclin B1 proteins were downregulated in both HaCaT and HaCaTKD cells (t =3.95-11.21,P ＜0.05).Specifically,Cdc2 protein decreased in HaCaT cells(t =4.93-5.37,P ＜ 0.05)but there was no change in HaCaT~ cells.Conclusions 14-3-3σ protein affects the proliferation and cell cycle of HaCaT cells after UVB irradiation.14-3-3oσ co-activates the expression of Cdc2,Cdc25cand Cyclin B1 to mediate UVB-induced G2/M arrest in HaCaT cells.

ObjectiveTo investigate the effect of follow-ups on medical compliance behaviors and quality of life of patients with gastroesophageal reflux disease (GERD).Methods One hundred GERD patients who were hospitalized in our department from June 2012 to June 2013 were divided into intervention group (n=50) and control group (n=50) according to the random number table. Both groups received the same drug treatment and conventional nursing during hospitalization.The control group received periodically outpatient follow-ups,while the intervention group received professional follow-ups by trained nurses after discharge from hospital. The compliance behaviors and quality of life in these patients were assessed and statistically analyzed after 6 months nursing intervention or outpatient follow-up.Results With the implement of follow-up in patients with GERD,the intervention group was better than the control group in compliance behaviors,including the decrement of smoking and drinking,strong tea,coffee,having midnight snack and spicy food (P<0.05),but there was no difference in the behavior of staying-up between the two groups.Concerning the quality of life,the intervention group was significantly better than the control group in the 6 items excluding the physical and physiological functions (P<0.05).Conclusion Professional follow-ups can improve compliance behavior and quality of life of GERD patients.

Objective To investigate the histogenesis,clinicopathological features and biological behavior of goblet cell carcinoid (GCC) of the appendix. Methods 3 cases of GCC of the appendix were studied by light microscopy and immunohistochemistry. Results 3 cases all occured in men. Microscopically: the tumor was composed of goblet cells containing mucin-filled with basal round to crescentic nuclei without atypia.These tumor cells were arranged in single forms,nests or acinus with no central lumen. 1 case was composed of simple goblet cells and typical carcinoid cells were seen in other 2 cases arranged in trabeculae and tubule.There was transition between goblet cells with tubelar and crypt epithelium.Immunohistochemical staining revealed that goblet cells were positively reacted with CgA, Syn, CEA, CK and p53 in 1 case. Conclusions Goblet cell carcinoid of the appendix arise from a pluripotent cell with divergent neuroendocrine and mucinous differentiation .It is a subtype of carcinoids of the appendix.The diagnosis mainly bases on its morphologic changes and immunohistochemical findings. The unpredictable behavior of this tumor is probably related to its component and the degree of infiltration.
