Rice straw degradation with white rot fungi and cellulose multienzyme was studied. The results indicated that the LiP, MnP activity produced by P. chrysosoporium 172 could reach 28.3U/g and 12.6U/g respectively under suitable culture condition. And the lignin was degraded efficiently in contrast with the cellulose and hemicellulose in rice straw solid fermentation. Following treatment with white rot fungi, using multienzyme produced by A. niger NL-1 could greatly accelerate the decomposition of rice straw. The decomposition rate of cellulose, hemicellulose, lignin and the loss rate of dry material were 53.8%,57.8%,44.5% and 46.3% respectivity when hydrolysis rice straw 48h with cellulase multienzyme (including 3 IU /g rice straw) after culture P. chrysosoporium 172 for 10 days. Scanning electron microscope analysis showed the cell wall of rice straw was destroyed severely, and the whole tissue got loosely. These results demonstrated the rice straw had been decomposed efficiently and completely.

Objective To study feasibility of differentiation of benign and malignant by using eccentric rate of calcification in pulmonary spherical lesions.Methods Two hundred and forty cases with pulmonary spherical lesions(malignant in 170 and benign in 70) confirmed by pathology or clinical follow-up were collected in this study.All cases were underwent chest CT examinations.Nodule CAD software was used to demarcation of pulmonary spherical lesions and internal calcification.Calcification was defined as an area more than 3 pixel with calcification density(CT value＞120 HU).Furthermore,the ratio of calcification center distanceand calcification edge distance was calculated as Ecc.Mann-Whitney U test was used to compare the eccentric calcification rates between the malignant and the benign pulmonary spherical lesions.Taking pathological results as golden standard,the diagnostic efficacy of Ecc was analyzed using ROC curves.Results In 240 lesions,65 calcifications were detected,of which 18 were malignant calcification distributed in 10 lesions,and 47 were benign calcifications distributed in 16 lesions.The median of Ecc in benign and in malignant lesions were 0.80(0.28-1.29) and 3.01(1.52-4.47).The Ecc of calcification in benign lesions were lower than those in malignant lesions (U=183.000,P＜0.01).Under the cut-off value of 1.00,benign calcifications were more likely to lie inner 1/2 part of lesion [61.70％(29/47)],while malignant calcifications were more likely to lie outer 1/2 part of lesion [77.78％(14/18)].The difference was statistically significant(x2=8.117,P＜0.01).Under the cut-off value of 1.72,the resultant sensitivity,specificity,accurate rate were 83.1％,77.8％,81.5％ respectively.The area under the ROC was 0.804.Conclusions Ecc exhibits the location characteristics of calcification and may be an ideal parameter in quantitative diagnostic modeling for providing evidence of quantitative diagnosis.

Objective To investigate the impact of polyclonal neural cell adhesion molecule antibody (P-NCAM-Ab) on the potency of botulinum toxin A (BTX-A).Methods Ninety male Sprague-Dawley rats were randomly divided into 3 equal groups:a normal control group,a BTX-A group and a P-NCAM-Ab group.The rats in the normal control group were injected with 100 μl of saline solution in their right gastrocnemius,while those in the BTX-A and P-NCAM-Ab groups were injected with 100 μl of BTX-A (0.5 U).In addition,the rats in the P-NCAM-Ab group were also injected with 100 μl of P-NCAM-Ab (the dosage was 20 U) at the same site on the 3rd day after the BTX-A injection.The rats' gastrocnemius muscle strength was evaluated with a self-made system for evaluating neuromuscular function before and after the toxin injection,on the 3rd day,as well as 1,2,4,6,8,10 and 12 weeks after the BTX-A injection.Any wet weight changes in the muscles were observed,and immunochemistry methods were employed to observe any structural changes in the motor endplates and nerve fibers at the different time points.Results After the saline injection,the average gastrocnemius muscle strength of the control group increased with time,while strength in the BTX-A and P-NCAM-Ab groups demonstrated a decrease in strength followed by a gradual increase.The average gastrocnemius muscle strength of the rats in the BTX-A and P-NCAM-Ab groups was significantly lower than that of the control group at all time points.Compared with the BTX-A group,the muscle strength of the P-NCAM-Ab group rats decreased further.Strength recovery in the BTX-A and P-NCAM-Ab groups was significantly slower than in the control group.The wet weight percentage in the BTX-A and P-NCAM-Ab groups at first decreased and then recovered with time.After the BTX-A injection,the average wet weight percentage of the P-NCAM-Ab group rats was significantly lower than that of the BTX-A group after 3 days,and 1,2 and 4 weeks.Karnovsky-Roots AchE staining showed that the motor endplates' color in the BTX-A and P-NCAM-Ab groups deepened gradually,though the color of the P-NCAM-Ab group was lighter than that of the BTX-A group at each time point.The mean optical density of the motor endplates' positive reaction area increased with time in both groups,but the P-NCAM-Ab group was lower than that of the BTX-A group at 1,2,4,8 and 12 weeks.Counting the nerve fibers dyed by gold chloride showed similar trends with both experimental groups significantly different from the control group.Conclusion P-NCAM-Ab can increase the potency of BTX-A and prolong its action.
