Objective: To use vertical and humidity correcting method to calibrate aerosol optical depth (AOD), and to explore the feasibility of calibrated-AOD as exposure index to measure the level of air pollutants from the ground and to establish the exposure-response relationship between calibrated-AOD and people's health outcomes.Methods: First of all, we interpolated AOD, PM2.5, relative humidity and planetary boundary layer height using Kriging method to obtain data at different locations and matched different data with respiratory death in Beijing by geographical coordinates.Then, the planetary boundary layer height and aerosol hygroscopic growth factor calculated based on relative humidity was used to calbrate the AOD.To compare the effects of calibrated-AOD and PM2.5, we used standardization method to get non dimensionless calibrated-AOD and PM2.5.At last, we used the generalized additive mixed model (GAMM) to estimate the acute effects of calibrated-AOD and PM2.5 on respiratory death and chronic obstructive pulmonary disease (COPD) death, after controlling the time trend, temperature and humidity effects, days of the week effect and holiday effects.Results: The correlation coefficient between calibrated-AOD and PM2.5 was 0.72.The effects of calibrated-AOD on respiratory death and COPD death was the strongest at lag 0-3, one unit of calibrated-AOD increases was associated with 3.64% (95%CI: 0.58%-6.78%) increase of respiratory death and 4.92% (95%CI: 1.81%-8.14%) increase of COPD death.As for PM2.5, the strongest effects appeared at lag 0-1, one unit of PM2.5 (about 155 μg/m3) increases was associated with excess risks of 3.96% (95%CI: 0.82%-7.19%) and 6.12% (95%CI: 1.44%-11.02%) for respiratory death and COPD death respectively.Compared with PM2.5, the effects of calibrated-AOD on respiratory death and COPD death had narrower confidence intervals.The calibrated-AOD was sensitive to capture the lag effects, and the cumulative lag effects of calibrated-AOD were all significant on multiple lag days which indicated that the calibrated-AOD was sensitive to capture cumulative lag effects of air pollutants on respiratory death and COPD death as well.Conclusion: We believe that calibrated-AOD can be used as an index to reflect the effects of air pollutants on respiratory death in Beijing.In the absence of ground monitoring, calibrated-AOD can be used to mea-sure the relationship between air pollutants and some health outcomes.

Objective:To investigate the effects and mechanism of β-carotene on inflammatory factors (IL-1 β,IL-6,TNF-α) in LPS-induced RAW264.7 cells.Methods:Firstly,RAW264.7 cells of being induced by 4 (5 μg/ml)for 24 h were treated with different concentration of β-carotene (20,40,80,160 pmol/L)for 3 h.The cells viability was measured by MTIT,the mRNA relative expression of IL-1 β,IL-6,TNF-cα was detected by fluorescence quantitative PCR,the secretion capacity of IL-1 β,IL-6,TNF-α was detected by ELISA and the protein relative expression of NF-κB p65 protein was measured by Western blot.Secondly,RAW264.7 cells were induced by LPS(5 μg/ml) and different concentration of PDTC(1,5,10 μg/ml)for 24 h,NF-κB p65 protein was measured by Western blot and inflammatory factors were detected by fluorescence quantitative PCR and ELISA.Finally,compared the changes in the relative expression of inflammatory factors and NF-κB p65 protein between LPS+PDTC group and LPS+PDTC + β-carotene group.Results:Compared with the LPS-induced group,β-carotene could increase the cell viability of LPS-induced RAW264.7 cells and inhibied the relative expression of inflammatory factors and NF-κB p65 protein.Inhibited the relative expression of NF-κB p65 protein could reduce the relative expression of inflammatory factors.Compared with the LPS+PDTC group,LPS +PDTC + β-carotene group could inhibit the relative expression of inflammatory factors significantly (P＜0.05).But,there was little difference about the relative expression of NF-κB p65 protein between this two groups.Conclusion:β-carotene inhibits the relative expression of inflammatory factors(IL-1 β,IL-6,TNF-α) in LPS-induced RAW264.7 cells through inhibition of NF-κB p65 protein in NF-κB pathway,this pathway isn't unique.

Objective To compare the efficacy and safety of 5-fluorouracil and calcium folinatc combined with oxaliplatin (FOLFOX) program with capecitabine regimen combined oxaliplatin (XELOX) program as adjuvant chemotherapy in advanced colorectal cancer after surgery.Methods The postoperative clinical data of 286 advanced colorectal cancer patients were retrospectively analyzed.Of which,204 patients received FOLFOX4/6 adjuvant chemotherapy and 82 patients received XELOX adjuvant chemotherapy.The three-years disease-free survival (DFS) time,three-years overall survival (OS) time and adverse reactions of the two groups were compared.Count data of the two groups' were compared by chi-square test,and measurement data were analyzed by t-test.Results In the FOLFOX4/6 group,153 patients (75 ％) completed 12 cycles of chemotherapy,and in the XELOX group,66 patients (80 ％) finished eight cycles of chemotherapy.There was no statistical difference in three-year DFS incidence (FOLFOX4/6 stage Ⅱ 87％,Ⅲ 82％; XELOX stage Ⅱ 83％,Ⅲ 80％) and three-year OS incidence (FOLFOX4/6 stage Ⅱ 92％,Ⅲ 88％; XELOX stage Ⅱ 89％,Ⅲ 86％) between two groups (all P＞0.05).There was no statistical difference in the incidence of common adverse reactions between FOLFOX4/6 and XELOX group (all P＞0.05).Adverse reactions of degree Ⅰ and Ⅱ were more common,while degree Ⅲ and Ⅳ were seldom.Of the adverse reactions of degree Ⅲ and Ⅳ,the incidence of neutropenia in patients of FOLFOX group was a little higher than in those of XELOX group,and the incidence of hand-foot syndrome was a litter higher in XELOX group than in FOLFOX group.However,there was no significant difference (x2 =0.060,0.928,both P＞0.05).Conclusion There was no statistical significance between FOLFOX4/6 and XELOX as postoperative auxiliary chemical therapy for advanced colorectal cancer,and both therapies possess good tolerance and safety.

Objective To analyze the correlation between clinical mental personality,coping style,social support and depression,anxiety for patients with chronic hepatitis B,and their treatment strategies.Methods A total of 66 patients with chronic hepatitis B (CHB group) and 72 normal people (control group) were investigated by the questionnaire,such as the demographic history questionnaire,Eysenck Personality Questionnaire (EPQ),Trait Coping Style Questionnaire (TCSQ),Perceived Social Support Scale (PSSS),Hamilton Depression Scale (HAMD),Hamilton Anxiety Scale (HAMD) were assessed.Results The HAMD score and HAMA score of hepatitis B group were significantly higher than that of the control group.Pearson correlation analysis showed that depressive symptoms was negatively correlated with positive coping,family support,extroversion,and was positively correlated with neuroticism.Multiple linear regression analysis showed family support,active coping,neuroticism and psychosis were all included in the regression equation and can predict depressive symptoms (3 values,0.002,0.003,0.004,0.022,respectively).Neuroticism,positive responded to the two independent variables (β values,0.003,0.011,respectively) into the regression equation,and can predict anxiety symptoms.Conclusion The patients with chronic hepatitis B were more prone to suffer from depression and anxiety than normal people,depressive symptoms are closely related to the neuroticism and neuroticism.The anxiety symptoms are related to neuroticism.The neurotic personality traits,lack of positive coping strategies and out-of-home support may lead to depression and anxiety.Depression and anxiety symptoms can be avoided by improving the patient's personality characteristics,and actively responding and enhancing the social support system outside the home soas to reduce depression,anxiety symptoms in patients with hepatitis B.

Bacille Calmette-Guérin (BCG) vaccine is designed to provide protection against tuberculosis (TB). However, numerous epidemiological, clinical, and immunological studies have shown that BCG vaccination affects neonatal and infant mortality, which may be related to the reduction of TB-unrelated infections and diseases by BCG vaccine. We aimed to discuss the off-target effects of BCG vaccine on un-TB infections and diseases, as well as the potential mechanism and influencing factors. Literature was retrieved mainly from PubMed using medical subject headings "BCG, variations, and non-specific, heterologous or off-target". Studies have showed that BCG vaccination can prevent various heterologous infections, including respiratory tract infections, leprosy, and malaria, treat viral infections including human papillomavirus and herpes simplex virus infection as immunotherapy, and improve the immune responses as vaccine adjuvant. Besides, BCG vaccine can reduce the recurrence rate of non-muscle-invasive bladder cancer, and may provide protection against autoimmune diseases. These off-target effects of BCG vaccine are thought to be achieved by modulating heterologous lymphocyte responses or inducing trained immunity, which were found to be sex-differentiated and affected by the BCG vaccine strains, sequence or time of vaccination.

OBJECTIVETo study the immunogenicity and safety of recombinant yeast-derived hepatitis B vaccine (YDV) in adults.

METHODSOne hundred and twenty-four healthy teachers aged 22 approximately 58 years with serum negative HBsAg, anti-HBs, anti-HBc and with normal temperature were randomly selected from Beipiao city, Liaoning province. All the subjects were immunized with 5 microg/0.5 ml of YDV made by Beijing Institute of Biologic Products, for three doses at an interval of one and six months, respectively.

RESULTSThe positivity of serum anti-HBs was 35.0%, 83.3%, 65.5% and 32.7% with a geometric mean titre (GMT) of 12.6 mIU/ml, 402.0 mIU/ml, 70.3 mIU/ml and 20.3 mIU/ml, respectively, three, seven, 12 and 24 months after immunization. The positivity and GMT of serum anti-HBs appeared the highest seven months after immunization, then began to decrease sharply. The positivity and GMT of serum anti-HBs in women was higher than that in men either three, or seven, or 12, or 24 months after immunization. The positivity of serum anti-HBs in those of 35 years or over was lower than that less than 35 years, seven months after immunization, but no age difference could be found 12 months after immunization. No local or systematic adverse reactions were found in all the subjects within three days after immunization.

CONCLUSIONThe recombinant yeast-derived hepatitis B vaccine (YDV) is immunogenic and safe for adults, but the persistency of serum anti-HBs in after immunization should be followed-up further.
