Objective To investigate the prevalence of allergic and infectious diseases in children, and to assess the influence of indoor and outdoor environmental factors on these two common diseases in children. Methods A questionnaire was used to investigate the prevalence of allergic and infectious diseases in 140 children of 7 years old in Laizhou Bay, Shandong Province. Logistic regression was used to analyze the associations between indoor and outdoor environmental factors and children’s allergic and infectious diseases, respectively. Results The prevalence of previous eczema and other allergic diseases for the past year in children was 37.9% and 15.0%, respectively, and the prevalence of infectious diseases for the past year was 35.7%. As for allergic diseases, eye irritation due to outdoor air ( OR =2.977; 95% CI : 1.407‒6.296) and nose irritation due to outdoor air ( OR =5.147; 95% CI : 1.272‒20.827) were the risk factors for previous eczema in children. Indoor musty taste increased the risks of urticaria ( OR =4.306; 95% CI : 1.062‒17.454) and previous eczema ( OR =3.853; 95% CI : 1.080‒13.743). The use of cockroach killers indoors increased the risk of rhinitis ( OR =6.102; 95% CI :1.297‒28.697). As for infectious diseases, having outdoor pollution sources increased the risk of gastrointestinal infection ( OR =4.937; 95% CI : 1.050‒23.216), and the use of mosquito coils and clothing mothproofing agents increased the risks of respiratory ( OR =6.333; 95% CI : 1.397‒28.714) and gastrointestinal infections ( OR =3.218; 95% CI : 1.074‒9.644), respectively. However, we did not find associations between indoor passive smoking and allergic or infectious diseases. Conclusion Except outdoor passive smoking, all the other indoor and outdoor environmental factors increase the risks of children’s allergies and infectious diseases.

Induction of immunogenic cell death promotes antitumor immunity against cancer. However, majority of clinically-approved drugs are unable to elicit sufficient ICD. Here, our study revealed that mitochondria-targeted delivery of doxorubicin (DOX) massively amplified ICD via substantial generation of reactive oxygen species (ROS) after mitochondrial damage. The underlying mechanism behind increased ICD was further demonstrated to be ascribed to two pathways: (1) ROS elevated endoplasmic reticulum (ER) stress, leading to surface exposure of calreticulin; (2) ROS promoted release of various mitochondria-associated damage molecules including mitochondrial transcription factor A. Nevertheless, adaptive upregulation of PD-L1 was found after such ICD-inducing treatment. To overcome such immunosuppressive feedback, we developed a tumor stimuli-responsive nano vehicle to simultaneously exert mitochondrial targeted ICD induction and PD-L1 blockade. The nano vehicle was self-assembled from ICD-inducing copolymer and PD-L1 blocking copolymer, and possessed long-circulating property which contributed to better tumor accumulation and mitochondrial targeting. As a result, the nano vehicle remarkably activated antitumor immune responses and exhibited robust antitumor efficacy in both immunogenic and non-immunogenic tumor mouse models.

Objective:To understand the levels of Pb, Cd, As, Hg, Mn, and Se in maternal and umbilical cord blood, and to explore the transplacental transfer efficiency (TTE).Methods:From September 2010 to December 2013, a total of 773 pregnant women and their newborns (Laizhou Bay Birth Cohort) were recruited from a second grade hospital in the south bank of Laizhou Bay, Bohai, Shandong Province. According to different detection methods, the six measured elements are classified into three groups including the Hg measurement group (595 mother-newborn pairs), the Pb measurement group (534 mother-newborn pairs), and the Cd, As, Mn and Se measurement group (244 mother-newborn pairs). The demographic characteristics of pregnant women and their newborns were obtained by the questionnaire. The concentrations of elements in maternal and umbilical cord blood were detected and the TTE of each element (elemental concentration in cord blood/elemental concentration in maternal blood) was calculated. The correlation of elements between maternal and cord blood was analyzed using Spearman′s rank correlation coefficient.Results:The mean± SD of maternal age, gestational week and newborn birth weight of 773 mother-infant pairs were (28.34±4.50) years, (39.47±1.39) weeks and (3 419.47±497.39) g respectively. The median concentrations of Pb, Cd, As, Hg, Mn and As in maternal and cord blood were 31.12 and 30.02, 1.19 and 0.47, 8.05 and 6.03, 0.69 and 1.26, 100.70 and 105.55, 127.25 and 115.00 μg/L, respectively. The TTE of Pb, Cd, As, Hg, Mn, and Se was 0.98, 0.41, 0.73, 1.73, 0.96 and 0.91, respectively. Pb, Cd, Hg, Mn, and Se showed a significant positive correlation between maternal blood and cord blood, with Spearman correlation coefficients of 0.397, 0.298, 0.698, 0.555, and 0.285 (all P values<0.001). Conclusion:Each element was commonly detected in maternal blood and cord blood. The TTE of Hg was the highest.

Objective To observe the effects of Eldepryl on expressions of tyrosine hydroxylase (TH) and glial cell line-derived neurotrophic factor (GDNF) in substantia nigra and striatum in Parkinson’s disease (PD) and to explore the protective mechanism of Eldepryl on dopaminergic neuron . Methods Healthy male Sprague-Dawley (SD) rats (n=72) were randomly divided into control group, model group and Eldepryl group (n=24 in each group). Each group was divided random?ly into 2 subgroups as 4 day treatment group and 8 day treatment group (n=12 in each subgrop). Pakinson’s disease model was established by injecting rotenone subcutaneously back the neck, rats in the control group were injected with an equal vol?ume of sunflower oil subcutaneously at the same location. Rats in the Eldepryl group were then given Eldepryl 0.5 mg·kg-1 in?tragastrically every day for 4 or 8 consecutive days and rats in model group and control group were given an equal volume of saline instead. The expression of TH and GDNF in substantia nigra and striatum were detected by immunohistochemistry and Western blotting. Results Immunohistochemistry and Western blotting showed that strong expression of TH positive cells with little expression of GDNF positive cells were seen in substantia nigra and striatum in rats of control group, and there was no significant difference between subgroup of 8 day treatment and 4 day treatment within control group. The expression of TH cells and GDNF were both significantly reduced in model group compared with those in control group (both P<0.05), and there was no significant difference between subgroup of 8 day treatment and 4 day treatment within each group. The ex?pression of TH positive cells were significantly reduced in Eldepryl group compared with those in control group, and were sig?nificantly increased compared with those in model group. The expression of GDNF positive cells were significantly increased in Eldepryl group compared with those in control group and model group (all P<0.05). And there were significantly more ex?pression of TH positive cells and GDNF positive cells at subgroup of 8 day treatment compared with those at subgroup of 4 day treatment within Eldepryl group with (all P<0.05). Conclusion These data suggest that Eldepryl can protect the dam?age of dopaminergic neurons in substantia nigra and striatum of PD rats. And its therapeutic mechanism may be associated with increased expression of GDNF.

Objective To explore the application value of pulse induced contour cardiac output (PiCCO) monitoring in diagnosis and treatment of patients with neurogenic pulmonary edema (NPE).Methods With review of literature, the data of 4 patients of severe neurological disease complicated by NPE admitted into Department of Critical Care Medicine of Huangshan People's Hospital Affiliated to Wannan Medical College from 2011 to 2013 were retrospectively analyzed and discussed in their PiCCO hemodynamic characteristics and processes of treatment.Results The PiCCO of 4 patients with NPE showed that the extravascular lung water index (EVLWI) was increased significantly (EVLWI was 12 - 42 mL/kg on admission and 10 - 22 mL/kg after hospitalization for 24 hours), all revealing a high permeability pulmonary edema type. The capacity balance of the first 24 hours in the 4 cases was all of positive balance (+1 130, +1 200, +1 750, +1 120 mL respectively). In the treatment, the supplementary colloid was strengthened, the vasoactive drugs such as, dopamine, dobutamine, milrinone, etc were applied to improve the circulatory oxygenation, then the EVLWI was declined; finally the disease situation in 3 cases was improved and one died.Conclusions The clinical diagnosis and treatment of NPE is complex, and many contradictions appear in the therapeutic course. PiCCO monitoring is valuable in early diagnosis, identification of pulmonary edema type, guidance in fluid supplement and vascular active drug application, and assessment of disease severity and prognosis.
