The effects of elevated CO2 on foliar chemistry of two tree species （Populus pseudo-simonii Kitag. and Betula platyphylla） and on growth of gypsy moth （Lymantria dispar L.） larvae were examined. Furthermore, we focused on the comparison of results on the growth responses of larvae obtained from two methods of insect rearing, the nochoice feeding trial performed in the laboratory or in situ in open-top chambers. On the whole, both primary and secondary metabolites in the leaves of the two tree species were significantly affected by main effects of time （sampling date）, CO2 and species. Elevated CO2 significantly increased the C： N ratio and concentrations of the soluble sugar, starch, total nonstructural carbohydrates, total phenolics and condensed tannins, but significantly decreased the concentration of nitrogen. Higher contents of total phenolics and condensed tannins were detected in the frass of larvae reared in elevated CO2 treatments. Overall, the growth of gypsy moth larvae were significantly inhibited by elevated CO2 and CO2- induced changes in leaf quality. Our study did not indicate the two methods of insect rearing could influence the direction of effects of elevated CO2 on the growth of individual insects; however, the magnitude of negative effects of elevated CO2 on larval growth did differ between the two insect rearing methods, and it seems that the response magnitude was also mediated by larval age and host plant species.

BACKGROUND Surgery 5-10 d after stent insertion was recommended by the European Society of Gastrointestinal Endoscopy for obstructing colonic cancer. For some obstructive patients, this may be not a good choice. Here, we report the successful treatment of obstructing colonic cancer by combining self-expandable stent and neoadjuvant *** SUMMARY The patient was a 72-year-old man who was admitted with a chief complaint of abdominal pain for more than 1 mo. Computed tomography(CT) scanning revealed that there was a mass in the descending colon, which led to intestinal obstruction. On admission, a series of therapeutic measures, such as fasting and water deprivation, gastrointestinal decompression, total parenteral nutrition, and octreotide acetate, were taken to improve the obstructive symptoms. At the same time, a self-expandable metal stent was successfully placed across the stenosis,and a biopsy was obtained and diagnosed as adenocarcinoma. CT scanning 14 d after insertion of the stent revealed that the intestine was swollen *** chemotherapy with modified FOLFOX6(mFOLFOX6) was administered. After two courses of mFOLFOX6, CT scanning showed clearly that swelling of the intestine was improved. Subsequently, the patient underwent left hemi-colectomy without stoma placement. The postoperative course was uneventful, and he has been disease-free for 6 mo after *** This modified treatment strategy may provide an alternative therapy for patients with obstructing colonic cancers.

Via multi-dimensional gas chromatography, configured with parallel dual-channel, double detectors, valves switching and back flushing, rapid analysis of the gas compositions consisting of C1-C5 hydrocarbons and permanent gases, such as CO2, H2S, H2, and CO, for direct coal liquefaction has been realized. With four packed chromatographic columns, which are Hayesep-Q pre-column, Hayesep-Q column, molecular sieve 5A column and one PLOT A1203 S capillary column, the gas compositions for direct coal liquefaction are analyzed qualitatively and quantitatively by the external standard method. The determination method has such advantages as excellent separation, simple operation, rapid analysis and accurate results.

Spontaneous hematomas are rare and most occur secondary to hematologic disorders or during anticoa- gulant therapy. Most spontaneous hematomas occur above the sigmoid colon, and rarely in the rectum. Herein we present the case of a patient with a spontaneous perforating hematoma of the rectum who presented with severe abdominal pain after a bloody stool. The hemoglobin level decreased by 33 g/L within 20 h. An abdominal sonogram showed a hydrops in the lower abdomen with a maximum depth of 7.0 cm. A hematoma, 8 cm x 6 cmx 5 cm in size, was noted intra-operatively in the rectosigmoid junction, with a 1.5-cm perforation in the hematoma and active hemorrhage. Thus, a partial rectectomy and sigmoidostomy were performed. Three months later, a second opera- tive procedure to re-establish intestinal continuity was performed. The patient is in good condition 12 mo after the last surgery. In addition to this case, the causes of spontaneous perforating hematomas and the treatment are discussed.

Carbon nanotubes(CNTs) have garnered great attention in recent years due to their outstanding electrical, thermal, and mechanical properties. The incorporation of small amounts of CNTs in polymers can substantially improve the sensitivity of the polymer's electrical conductivity. This paper presents a modified Maxwell model to evaluate the electrical conductivity of CNTs-filled polymer composites by introducing a transition zone to account for the tunneling effect. In this modified Maxwell model, the CNTs-filled polymer composite is modeled as a three-phase composite, consisting of a matrix(polymer), inclusions(CNTs), and a transition zone(tunneling zone). The effective electrical conductivity(EEC) of the composite is calculated based on the volume fractions and electrical conductivities of the matrix, inclusions, and transition zone. The model's validity is confirmed through the use of available test data, which demonstrates its capability to accurately capture the nonlinear conductivity behavior observed in CNTs-polymer composites. This study offers valuable insights into the design of high-performance conductive polymer nanocomposites, and enhances the understanding of electrical conduction mechanisms in CNT-dispersed polymer composites.
