Objective To analyse the clinical significance of (IL-5),interleukin-6 (IL-6),interleukin-8 (IL-8),eosinophil cationic protein (ECP),eosinophil (EOS),immunoglobulin E (IgE),vascular endothelial growth factor (VEGF) and its receptor in serum of children with infectious pneumonia.Methods 80 children with infectious pneumonia were enrolled in Lianyungang Maternal and Child Health Hospital from March 2016 to March 2017,and were included in the observation group.According to the pathogen type,these children in the observation group were divided into virus group,mycoplasma infection group and bacterial infection group.At the same time,30 healthy children were selected as the control group.The levels of TNF-α,IL-5,IL-6,IL-8,ECP,VEGF,VEGF-R1 and VEGF-R2 in serum were measured by enzyme-linked immunosorbent assay (ELISA).The levels of EOS in blood were measured by automatic blood cell analyzer and the level of lgE in serum was detected by immunoturbidimetric turbidimetric assay.Results The levels of TNF-α,IL-5,IL-6,IL-8,ECP,VEGF,VEGF-R1,VEGF-R2,EOS and IgE in the blood of the observation group were significantly higher than those in the control group (t=2.325 ~ 3.593,all P<0.05).The levels of TNF-α,IL-5,IL-6 and IL-8 in the serum of the bacterial infection group were significantly higher than those in the virus group and mycoplasma group (all P<0.05).The levels of VEGF,VEGF-1 and VEGF-R2 in serum of patients with mycoplasma infection were significantly higher than those in the group of bacterial infection and virus infection (all P<0.05).Serum IgE levels and the number of peripheral blood EOS in the bacterial infection group,viral infection group and mycoplasma infection group had no significant difference (P>0.05).Conclusion The serum levels of TNF-α,IL-5,IL-6 and IL-8 can be used as markers for bacterial infectious pneumonia and viral infectious pneumonia and mycoplasma infectious pneumonia.

The traditional Chinese medicine of Radix Hedysari plays an important role in invigorating gas for as-cending, benefiting blood for promoting production of fluid, and promoting circulation for removing obstruction in collaterals, which is consistent with the principle of treatment for osteoporosis. This study is designed to investigate the bioactive components on increasing peak bone mass (PBM) by exploring the spectrum-effect relationship between chromatography fingerprints and effect. Multiple indicators are selected to evaluate the pharmacological activity. In fingerprints, 21 common peaks are obtained, five of which are identified. Furthermore, gray relational analysis (GRA) is a quantitative method of gray system theory and is used to describe the correlation degree of common peaks and pharmacological activities with relational value. 21 components are then divided into three different regions, of which ononin and calycosin play an extremely significant role in increasing PBM. In addition, factor analysis and hierarchical cluster analysis (HCA) are used to screen the optimal producing area for Radix Hedysari. This provides a comprehensive and efficient method to improve the quality evaluation of Radix Hedysari, confirming the bioactive components for PBM-enhancement and further develop its medicinal value.

Although a variety of regimens are available for the treatment of atopic dermatitis (AD), severe adverse reactions and unpopular costs often limit their usage. In contrast, certain inexpensive, naturally-occurring ingredients are proven effective for AD with fewer side effects. The beneficial effects of these ingredients can be attributed to inhibition of cytokine and chemokine expression, IgE production, inflammatory cell infiltration, histamine release, and/or the enhancement of epidermal permeability barrier function. Since herbal medicines are widely available, inexpensive and generally safe, they could be valuable alternatives for the treatment of AD, particularly for those patients who are not suitable for the utilization of immune modulators. In this review, we summarize the therapeutic benefits of natural ingredients for the treatment of AD and the mechanisms of their actions.

Objective To investigate the effect on radioactivity in drinking water around Qinshan nuclear power station (QNPS)in normal operational condition.Methods The field monitoring and laboratory analysis methods were adopted to detect the total radioactivity level in drinking water in 2015,according to different distances from the nuclear island and different types of water.Results The total alpha and total beta radioactivity level in drinking water around QNPS were 0.027(0.098)Bq /L and 0.263(0.071)Bq /L respectively,which were obviously lower than the national health standard limits(total alpha and total beta are 0.5,1.0 Bq /L respectively).Total radioactivity level had no relation with the distance from the nuclear island (P >0.05).The total alpha radioactivity in deep well water was the highest among the investigated three types of drinking water,and the highest value was 0.224 Bq /L.The beta radioactivity level in river water was the highest,and the highest value was 0.408 Bq /L.The total alpha radioactivity level was 0.017 (0.013)Bq /L in 2015, higher than the average level during 2010—2014.The beta radioactivity average level was 0.319 (0.102)and 0.289 (0.055)Bq /L,also higher than the average level during 2010—2014.Conclusion The total radioactivity in drinking water among nuclear power plant is in normal background level,so at present there is no effect of the radioactive contamination on drinking water around QNPS in nuclear power plant's normal operational condition.

Objective To establish a high performance liquid chromatography (HPLC) through the optimization of the chromatographic conditions, which can detect the contents of clenbuterol hydrochloride (CL) residues in animal edible product in a large quantity. Methods The animal edible product were extracted by perchloric acid, and then impurities were removed by liquid-liquid extraction (LLE) which used ethyl acetate- isopropanol. After the organic phase was concentrated, C18 column (150 mm×4.6 mm, 5 μm) was used to separate CL. Mobile phase were methanol-sodium dihydrogen phosphate, and then determined by HPLC. Results A good linear response was obtained over the range of 0.2-10.0 μg/mL with the correlation coefficient (r) 0.99984. The method determination limit was 0.15 μg/kg which was lower than the National standard method 0.5μg/kg. The retention time of the CL was 6.51 min, the chromatographic peak was good. The recovery rates spiked with standards 1.6-12 μg were 92.86%-100.93%, which was higher than National standard method (89.79%-92.36%) . The precision of intra-day and inter-day were both under 5%, which lower than National standard. Conclusion The optimized chromatographic conditions are suitable for the large quantity determination of clenbuterol hydrochloride in animal edible product.

Dendrobii Caulis (DC), named 'Shihu' in Chinese, is a precious herb in traditional Chinese medicine. It is widely used to nourish stomach, enhance body fluid production, tonify "Yin" and reduce heat. More than thirty Dendrobium species are used as folk medicine. Some compounds from DC exhibit inhibitory effects on macrophage inflammation. In the present study, we compared the anti-inflammatory effects among eight Dendrobium species. The results provided evidences to support Dendrobium as folk medicine, which exerted its medicinal function partially by its inhibitory effects on inflammation. To investigate the anti-inflammatory effect of Dendrobium species, mouse macrophage cell line RAW264.7 was activated by lipopolysaccharide. The nitric oxide (NO) level was measured using Griess reagent while the pro-inflammatory cytokines were tested by ELISA. The protein expressions of inducible NO synthase (iNOS), cyclooxygenase-2 (COX-2) and mitogen-activated protein kinases (MAPKs) phosphorylation were evaluated by Western blotting analysis. Among the eight Dendrobium species, both water extracts of D. thyrsiflorum B.S.Williams (DTW) and D. chrysotoxum Lindl (DCHW) showed most significant inhibitory effects on NO production in a concentration-dependent manner. DTW also significantly reduced TNF-α, MCP-1, and IL-6 production. Further investigations showed that DTW suppressed iNOS and COX-2 expression as well as ERK and JNK phosphorylation, suggesting that the inhibitory effects of DTW on LPS-induced macrophage inflammation was through the suppression of MAPK pathways. In conclusion, D. thyrsiflorum B.S.Williams was demonstrated to have potential to be used as alternative or adjuvant therapy for inflammation.
