World Science and Technology-Modernization of Traditional Chinese Medicine 2013;(3):446-454
This review summarizes the present situation of research, development and application of the Chinese herbal feed additives and its prospect. It can provide scientific references for researchers to carry out in-depth study. Chinese herbal feed additives will hopefully solve problems such as antibiotic residues, environmental pollu-tion, low productivity which hinders the development of livestock and provides strong support for developing green husbandry, meeting the food safety demand, closing the gap of livestock between the developed countries and Chi-na, increasing competitiveness of Chinese animal products in world markets. The development of Chinese herbal feed additives have very important economic and social benefits.

Objective: To study the biotransformation of Poria cocos by Ganoderma lucidum and the changes of total polysaccharide and total triterpenes contents of the biotransformation products. Method: The experiment uses the microwave method to extract and sulfuric acid-phenol method to measure total polysaccharide content. And the ultrasonic wave method was used to extract total triterpenes and the content was measured by vanillin-perchloric method. Result: After treatment by G. lucidum, the total polysaccharide and triterpenes content of the biotransformation products were significantly higher than the non-conversed P. cocos (P<0.01), showing that the original performance of P. cocos was changed by way of biotransformation of G. lucidum; P. cocos had a promotion effect on the growth of G. lucidum. Conclusion: Biotransformation of P. cocos for Increasing the total polysaccharide and triterpenes contents by using G. lucidum has advantages of simple, low cost and so on. This method has a certain application value in modernization of Chinese traditional medicine.

Objective: To investigate the effect of macrophage-capping protein (CapG) on migration and proliferation of human gastric cancer cell line.Methods: Real-time PCR method was used to detect the expression of CapG gene in four gastric cancer cell lines, and AGS cells with low expression and transfection were selected as the research objects.Specific primers were designed for CapG and recombinant plasmids synthesized.A lentivirus packaging system which could express CapG was constructed, and a cell line stably expressing CapG was established by infecting human gastric cancer cell line AGS cells.The effect of overexpression of CapG gene on the growth and proliferation of AGS cells was analyzed by CCK8 assay.Cells cratch and Transwell assay were used to analyze the effect of overexpression of CapG gene on AGS cell migration.Results: After the overexpression of CapG, the growth rate of AGS cells was slightly lower than that of the control group, but there was no significant difference between the two groups (t=2.424, P=0.073).Scratch test showed that the average narrowing distance of the scratches in the CapG experimental group was significantly reduced compared with the control group, the average narrowing distance of the CapG experimental group and the control group was 336.99 μm and 45.54 μm, the difference was statistically significant (t=14.97, P=0.004).The average number of cell penetra-ting membrane in the CapG experimental group and the eGFP control group was 176 and 70, the number of the cells in the CapG experimental group was significantly higher than that of the control group (t=40.00, P<0.001).Conclusion: The overexpression of CapG gene has no significant effect on the growth and proliferation of AGS cells of gastric cancer cell line.Overexpression of CapG gene can promote the migration of AGS cells of gastric cancer cell lines.

Objective:To investigate the relationship between the serum high mobility group box 1 (HMGB1) level and children with febrile convulsion(FC) and epileptic seizures in the future.Methods:A total of 359 children with first-episode FC occurring in January 2014 to January 2017 admitted to the Department of Pediatrics, Henan Provincial People′s Hospital, were enrolled in the FC group.One hundred children without FC were enrolled in the fever control group, and 100 healthy children were enrolled in the healthy control group.Children with FC were followed for 18 months and their seizures were recorded.Serum HMGB1 and inflammatory response indexes were measured in all subjects, and the diagnostic value of HMGB1 for FC was analyzed.Other data were used to analyze the correlation between HMGB1 and the conversion of FC into epilepsy.Results:The level of serum HMGB1 in the FC group were hig-her than those in the healthy control group and the fever control group, and the differences were statistically significant [(3.04±1.01) μg/L, (5.09±1.45) μg/L vs.(8.32±2.27) μg/L, all P<0.01]. serum HMGB1 level in children with FC was positively correlated with interleukin(IL)-1β, IL-6, tumor necrosis factor (TNF)-α, C-reactive protein (CRP) and white blood cell (WBC) ( r=0.364, 0.173, 0.227, 0.235, 0.247, all P<0.05). There were significant differences in HMGB1 levels between groups with different duration and types of convulsions [(8.11±2.15) μg/L vs.(10.19±2.51) μg/L, (7.63±1.93) μg/L vs.(9.83±2.25) μg/L, all P<0.05]; HMGB1 level diagnosis of FC was better [area under the receiver′s operating characteristic curve (AUC)=0.843 (95% CI: 0.811-0.873)]; Serum HMGB1 in children with epilepsy with FC was higher than that without conversion to epilepsy, and the difference was statistically significant [(8.18±2.14) μg/L vs.(8.95±2.73) μg/L, P<0.05]; However, its performance in predicting the conversion of FC to epilepsy was not high [AUC=0.596 (95% CI: 0.544-0.691)]; Multivariate regression analysis showed that it was not an independent influencing factor of FC to epilepsy [odd ratio( OR)=1.929, P=0.222]. Conclusions:Serum HMGB1 levels in children with FC are related to the onset, severity and type of fever, and are one of the influencing factors affecting the conversion of FC to epilepsy, but not the independent factors.

BACKGROUND:
More and more patients with small pulmonary nodules (SPN) can be found along with the developing of chest low-dose computed tomography (LDCT). With current examinations not all the SPN can be diagnosed to be benign or malignant and not all the malignant nodules can be diagnosed to be lymphatic metastasis. We need to study the correlation between plasma D-dimer count of patients before surgery with pathology features of non-small cell lung cancer (NSCLC).
METHODS:
The study comprised 567 highly suspected lung cancer patients. Preoperative plasma D-dimer were qualified, and the relationship between plasma D-dimer with pathology features including benign or malignant nodules, tumor size and involvement of lymph nodes was examined using Kruskal-Wallis test and Spearman correlation coefficients.
RESULTS:
The median plasma D-dimer values were statistically higher in NSCLC patients than in those who suffered from benign lung nodules (P<0.001). The median plasma D-dimer values in NSCLC patients with malignant lymph nodes were statistically higher than in those without malignant lymph nodes (P<0.001). An obvious relationship was observed between elevated D-dimer with number of malignant lymph nodes involvement and tumer size. An obvious relationship was observed between elevated D-dimer (>112.5 ng/mL) and malignant lymph node involvement in stage T1 lung cancer.
CONCLUSIONS
The plasma D-dimer maybe useful for early diagnosis, staging and prognosis of the patients with NSCLC. The plasma D-dimer can be one of the indicator to identify what kind of patients need mediastinal lymph node cleaning.
