Objective: To evaluate the effect of NGX6 with 5-Fu on the apoptosis of colon cancer cells. Methods: The NGX6-transfected HT-29 cell line with 5-Fu was used in the test group. HT-29 cell line with 5-Fu and PDTC was used in the control group. The expression of NF-κB was detected by EMSA. The proliferation of HT-29 cell line was assayed by MTT. The effect of NGX6 on the apoptosis was detected by FCM. HT-29 cells were double-stained by PI/Annexin-V and AO/EB and observed by fluorescence microscopy. Results: The expression of NF-κB was inhibited in NGX6 transfected colon carcinoma cell group and in colon carcino-ma cell group treated with PDTC. Treatment with the chemopreventive compounds 5-Fu and PDTC resulted in different responses in the effects of anti-proliferation and induced apoptosis of colon carcinoma cells. There was no significant difference in apoptosis between NGX6-transfected HT-29 call line with 5-Fu and the cells in the control group. NGX6 gene enhanced the effect of 5-Fu on the proliferation and apoptosis of colon carcino-ma cells. Conclusion: NGX6 gene can induce apoptosis and inhibit the proliferation of colon carcinoma cells. NGX6 gene can enhance the effect of 5-Fu on the proliferation and apoptosis of colon carcinoma cells through NF-κB pathway.

OBJECTIVE To have a systematic pathomechanism view of three chest impediment-syndromes of Qi Deficiency and Blood Stasis syndrome(QDBS),Qi Stagnation and Blood Stasis syn-drome (QSBS), Cold Obstruction and Qi Stagnation syndrome(COQS) and further investigate the changed metabolome and related pathways for screening potential biomarkers in rat plasma. METHODS According to clinical pathogeny, three kinds of syndrome models were established to simulate the disease of chest impediment. Plasma metabonomics based on UPLC-Q-TOF/MS was applied in this research to detected small molecule metabolites for identifyingthe special potential biomarkers of three chest impediment syndromes, respectively. RESULTS Significant metabolic differences were observed between thecontrol group and three syndrome groups. Furthermore, three syndrome groups were distinguished clearly by pattern recognition method.The particular metabolites contributing most to the classification of three chest impediment syndromes were identified. In the QSBS group, the potential biomarkers could include 2-keto-glutaramic acid, L-methionine, L-homocysteic acid, octadecanamide, stearoylglycine,behenic acid,linoleylcarnitine,lysoPC(14:1(9Z)),indoxyl sulfate and cholic acid.In the COQS group, they could be aminoadipic acid, palmitic amide, oleamide, lysoPC(P-16:0), lysoPC(P-18:0), lysoPC(20:2(11Z,14Z)), 9-HETE and tauroursodeoxycholic acid. Moreover, 4-pyridoxic acid, L-palmi-toylcarnitine, lysoPC(20:0), lysoPC (22:5 (4Z,7Z,10Z,13Z,16Z)), 3- hydroxyhexadecanoic acid and arachidonic acid could be the potential biomarkers for the QDBS group. CONCLUSION Three chest impediment syndromes have their own potential biomarkers.Each special metabolite has its owndifferent metabolic pathway.Both metabolismof cysteine and methionine,and metabolism of alanine,aspartate and glutamate are the main pathways in regulation of metabolic disorders in QSBS syndrome. Lysine biosynthesis and degradation,fatty acid metabolism,and glycerophospholipid metabolism are the main pathways in regulation of metabolic disorders in COQS syndrome.Arachidonic acid metabolism, fatty acid metabolism,fatty acid elongation in mitochondria,and vitamin B6 metabolism are the main pathways in regulation of metabolic disorders in QDBS syndrome.These endogenous substances were indicated as the special potential biomarkers for three chest impediment syndromes and worth studying in depth.

OBJECTIVETo analyze the epidemiological features of adverse events following immunization (AEFI) in Henan Province, China and to evaluate the safety of vaccines currently used in Henan.
METHODSThe AEFI cases reported in Henan from January 1, 2010 to December 31, 2011 were collected through the China Surveillance System of Information on National Immunization Program. The descriptive method was used for epidemiological analysis.
RESULTSA total of 2415 cases of AEFI were reported in Henan from January 1, 2010 to December 31, 2011, and 1238 (51.26%) of them were found in Zhengzhou, Luoyang, and Jiaozuo cities. The male-to-female ratio was 1.32:1. Seven hundred and ninety-nine (33.08%) of these cases were less than one year old. Measles vaccine and DPT vaccine (against diphtheria, pertussis, and tetanus) were the main causes of AEFI, contributing to 61.24% of cases; the incidence rates of AEFI among people receiving measles and DPT vaccines were 30.3/105 and 5.0/105, respectively. 1528 cases (63.27%) developed AEFI after the first dose of vaccination. Inflammation and allergic symptoms were the predominant adverse effects caused by the top 5 vaccines AEFI-causing vaccines, and the clinical manifestations were significantly different among AEFI cases caused by different vaccines (χ2=304.5, P<0.001). Among the 2415 AEFI cases, 1946 (80.58%) had common adverse reaction, 348 (14.41%) had rare adverse reaction, 98 (4.06%) had coupling disease, 13 (0.51%) had psychogenic reaction, and 10 (0.41%) had reaction for unknown reasons. The prognosis of most AEFI cases was good, with a cure rate as high as 90.64%.
CONCLUSIONSAEFI occurs mostly in young children and after the first dose of vaccination. This should be brought to the attention of vaccination service personnel and the children's parents.

This paper is aimed to provide the methods of quality control and bioassay of traditional Chinese medicine injections including bioassay method. Shuanghuanglian freeze-dried powder for injection (SFPI) was chosen as study object. HPLC-ELSD fingerprints of SFPI had been established and the samples were differentiated by similarity calculation. Meanwhile, biological profiles of SFPI on Escherichia coli had been established by microcalorimetry. The similarity values were calculated using the correlation coefficient, based on quantitative thermo-kinetic parameters (T2m, Tj, I%). The results indicated that HPLC-ELSD fingerprints, which showed content changes of chemical components, could not monitor minimal variation of different samples, especially that of biological pollutants, while biological profiles could sensitively detect antibiotic activity alterations of the samples, which were kept under specific conditions. In conclusion, characterized by two-dimension, microcalorimetry could supply thermograms as biological profiles characterized to describe the bioactivity of drugs. This study could clearly demonstrate that the correlative detection was proposed as an efficient strategy for quality control of SFPI, based on HPLC-ELSD fingerprints and biological profiles, which could detect quality fluctuation of samples early and quickly and predict the potential adverse drug events (ADE) for ensuring clinical safety.

OBJECTIVETo evaluate effects of inhaled nitric oxide (iNO) on the expression of lung neutrophil adhesion molecule CD(11b) in experimental meconium aspiration pneumonia treated with conventional mechanical ventilation under room air or 100% O(2).
METHODSRabbits were randomly allocated to 10 groups (n = 60), 6 of each group. Control or meconium aspiration pneumonia model groups were inhaled with room air or 100% O(2). Six treatment groups were treated with continuous NO inhalation at the doses of 6 x 10(-6), 10 x 10(-6) and 20 x 10(-6), respectively for 12 hours under room air or 100% O(2). The ratio of wet/dry (W/D) lung weight, alveolar septal width (ASW), myeloperoxidase (MPO) activity and lung injury score were measured. The expression of CD(11b) in neutrophils of the bronchoalveolar lavage fluid (BALF) was detected with flow cytometry.
RESULTSAfter 12 hours ventilation, the oxygenation was maintained better in treatment groups under different O(2) concentrations than that in model groups. Inflammatory evidence was found in lungs from all the model groups and treatment groups, which was characterized by serious inflammatory cell infiltration in alveolar space and hyaline membrane formation. The lung inflammation was decreased in all groups with nitric oxide inhalation. The ratio of W/D lung weight and ASW among different groups had no significant difference. MPO activities were significantly decreased in groups treated with 10 x 10(-6) and 20 x 10(-6) iNO compared with the model groups [with the concentration of 21% O(2), (1.8 +/- 0.2) U/g vs (4.4 +/- 0.5) U/g and (2.0 +/- 0.1) U/g vs (4.4 +/- 0.5) U/g;with the concentration of 100% O(2), (1.7 +/- 0.4) U/g vs (2.8 +/- 0.5) U/g and (1.4 +/- 0.3) U/g vs (2.8 +/- 0.5) U/g, P < 0.05, respectively]. MPO activities in the 20 x 10(-6) iNO group under 100% O(2) were significantly reduced compared with those under 21%O(2) [(1.4 +/- 0.3) U/g vs (2.0 +/- 0.1) U/g, P < 0.05]. Nitric oxide inhalation with the doses of 10 x 10(-6) and 20 x 10(-6) significantly decreased the expression of CD(11b) (MFI) in neutrophils of the BALF compared with the expressions in model groups without NO treatment (with 21% O(2), 121 +/- 20 vs 392 +/- 204 and 112 +/- 30 vs 392 +/- 204; with 100% O(2), 113 +/- 24 vs 293 +/- 65 and 102 +/- 14 vs 293 +/- 65, P < 0.05, respectively). Under the same iNO dose (10 x 10(-6) or 20 x 10(-6)) no statistic difference was found between groups of different inspired oxygen concentrations (21% and 100%).
CONCLUSIONSInhaled nitric oxide with the doses of 10 x 10(-6) to 20 x 10(-6) could significantly down-regulate the CD(11b) expression in neutrophil of the BALF and reduce the neutrophil sequestration and MPO activity in rabbit lungs, which may decrease the lung inflammation process in meconium aspiration pneumonia.

OBJECTIVETo explore the relationship between vitamin D receptor (VDR) gene pol-ymorphisms at Fok I site and the risk of preterm birth for potential intervention of of preterm birth or threatened premature delivery.
METHODSFifty-seven women with preterm birth and 84 with full-term birth were included in this analysis. Polymerase chain reaction-restriction frag-ment length polymorphism (PCR-RFLP) was performed to identify VDR gene Fok I geno-types.
RESULTSNo significant difference was found in age, D-dimer (DDI), fibrinogen (Fg), serum calcium (Ca), leukocyte count or glycosylated hemoglobin (HbA1c) level between the women in the preterm and full-term birth groups (P>0.05). The two groups differed signifi-cantly in the distribution of VDR gene Fok I site genotypes and allele frequency of F/F (P<0.05).The frequency of FF genotype was significantly higher in the preterm group than in the full-term group. Compared with Ff and ff genotypes, FF genotype was associated with an in-creased risk of preterm delivery (χ=9.701, P=9.701, OR=3.320, 95% CI [1.560, 7.066]). In the preterm group, the maternal age, DDI, Fg, serum Ca, leukocyte count or HbA1c did not differ significantly between the genotypes (P>0.05).
CONCLUSIONVDR gene Fok I site geno-types are related with preterm birth, and the FF genotype may serve as a potential risk factor for preterm birth.

OBJECTIVETo explore the mechanism of cake-separated moxibustion in treatment of hyperlipemia.
METHODSSixty rabbits were randomly divided into 4 groups, a blank group,a model group, a direct moxibustion group and a cake-separated moxibustion group. Hyperlipemia model was developed by high fat diet of cholesterol. Changes of ultrastructures of endothelial cells of the aorta of the rabbit were observed with electron microscope.
RESULTSThe endothelial cells in the cake-separated moxibustion group were more intact, most of them were normal in forms, internal elastic membrane was continuous, their thickness was even, the cells of smooth muscles in the medial membrane were relatively normal, which are similar to those in the blank control group. But the structure of endothelial cells of the aorta in the model group disappeared, in cytoplasm the sedimentation of a great number of lipids can be seen, internal elastic membrane was interrupted, the thickness was uneven, with focal dissolution, the cells of smooth muscle in the medial membrane had sedimentation of lipids, with frothy change.
CONCLUSIONCake-separated moxibustion has a certain protective action on endothelial cells of the aorta in the rabbit of hyperlipemia.
