Objective To investigate the short term efficacy of transcatheter arterial chemoembolization(TA-CE)combined with arsenic trioxide(AS203) in the treatment of primary liver cancer.Methods 91 patients with advanced primary liver cancer underwent routine hepatic arterial chemoembolization,repeated every 4 weeks for 2 to 3 cycles.In each cycle of chemoembolization,AS2O3 ,was injected intravenously once a day for 2 weeks at a dose of 10～15mg.Results All patients completed 2～3 cycles treatment and followed for more than one year.Total response rate was 61.7% and clinical benefit rate was 42 cases of partial response(PR) ,35 cases of no changes(NC) and 11 cases of progressive disease(PD).Quality of life improved in 61 cases and stabilized in 24 cases.Toxicifies was mild and tolerable.Conclusion TACE combined with arsenic trioxide in the treatment of primary liver cancer is efficient with a mild toxicities.

This paper investigated contamination situation of Listeria monocytogenes(Lm). To compare dif- ferent selectivity enrichment broth for detectable effect of Lm and compare detectable effect in different samples by using different methods, furthermore, choose the best enrichment broth for specific food. One hundred and thirty five random samples from raw meat, aquatic product, fruit and vegetable, quick-frozen food in Baoding. Applied LB enrichment broth, EB enrichment broth, new modification FDA enrichment broth and Fraser enrichment broth before separated by PALCAM selective agar, then identified by interna- tional standard method after PCR. Results: Four methods showed that there were 23 Lm positive, detected 5 Lm by LB method, 6 Lm by Fraser method, 5 Lm by EB method and 7 Lm by new modification FDA method. The total detectable rate of four methods had no large specificity, but to specific kind of food was different.

The protoplasts of original Aspergillus niger strain Uco-3 were treated with the cooperation of UV and ?-ray to obtain the high-yielding strain producing the thermostable ?-galactosidase. Under the optimum conditions of formation and regeneration protoplasts were prepared. According to the interaction of positive mutation rate and radiation dose,the optimum condition was determined. The optimum dose of UV was 4 minutes and the optimum dose of ?-ray was 500 Gy. After mutagenetic treatment of protoplasts and selection from a lot of mutants,a mutant DL116 producing the thermostable ?-galactosidase was obtained. The ?-galactosidase activity of DL116 was increased from 16.27 U/mL to 44.37 U/mL,which was higher than that of strain Uco-3.

OBJECTIVETo compare the difference in the efficacy on low back pain of cold-damp pattern between electric-thermal Bian-stone therapy and moxibustion box therapy.

METHODSForty-one cases of low back pain of cold-damp pattern were randomized into an electric-thermal Bian-stone therapy group (group A, 26 cases) and a box moxibustion therapy group (group B, 15 cases). In the group A, the electric-thermal Bian-stone was placed over Shenshu (BL 23) and Weizhong (BL 40). The temperature of stone was adjusted in accordance with patient's comfort. In the group B, moxibustion box was used over Shenshu (BL 23) and Weizhong (BL 40). The treatment was given once every day or every two days. Ten treatments made one session. The symptom and physical signs score of low back pain and the score of cold-damp syndrome were observed before and after treatment in the patients.

RESULTSThe symptom and physical signs score of low back pain and the score of cold-damp syndrome were all improved in the two groups (all P < 0.01). The changing rate of symptom and physical signs and syndrome were (37.04 +/- 32.68)% and (22.85 +/- 29.95)% in the group A, and were (47.29 +/- 22.08)% and (23.89 +/- 22.53)% in the group B, respectively, without significant difference in comparison between the two groups (all P > 0.05).

CONCLUSIONThe efficacy on low back pain of cold-damp pattern treated with the electric-thermal Bian-stone therapy is similar to that of moxibustion box therapy. This therapy is characterized as more convenient, safer operation and less pollution.

OBJECTIVETo establish a near-infrared qualitative analysis model to identify the authenticity of Polygonum multiflo- rum and distinguish processed products Polygoni Multiflori Radix.

METHODThe NIR spectra were peformed on over 30 batches of P. multiflorum and Polygoni Multiflori Radix samples and the adulterants Cynanchum bungei, Pteroxygonum giraldii, Polygonum cillinerve to establish the qualitative discriminant model and the conformity test model of Polygonum multifiorum , and cluster analysis was used to analyze the samples from different origins.

RESULTThe model is able to identify correctly P. multiflorum with its counterfeit, and distinguish between P. multiflorum and Polygoni multiflori Radix.

CONCLUSIONNear-infrared spectroscopy can be applied in the identification of P. multiflorum, which could be used to screen Chinese herbal medicine preliminarily.

Syndrome and formulae (or prescription) are two key issues in traditional Chinese medicine (TCM) and the premise research for material basis of TCM. However, vagueness of syndromes and complexity of formulae greatly limited the evaluation to syndromes and effective substance basis of prescription. Therefore, how to solve the evaluation of syndromes, confirming the efficacy material basis in prescription are the current hot issues of international concern. To solve these problems, establishing chinmedomics by integrated serum pharmacochemistry of TCM with metabolomics technology, that is a unique method of TCM research, made outstanding contributions in solving international concerns such as the effectiveness and security aspects of TCM. On the basis of the biological characterization of syndrome, the metabolic profiling of animal models of TCM syndrome, and related metabolic fingerprints as well as metabolic biomarkers were established to evaluate the overall effects of TCM formulae and corresponding relationship of syndrome-formulae. The active constituents were screened using the plotting of correlation between (endogenous) marker metabolites and (exogenous) serum constituents (PCMS), and is ongoing verification by further biological experiments. Correlation analysis between the ingredients in the body after oral formulae and endogenous markers in vivo can be used to clarify the active ingredients and synergistic properties. This method was successfully applied for rapid discovery of potentially bioactive components and metabolites from TCM, and through a series of studies on the chinmedomics, it proved that the established method could help to explore the effective substance for further research of TCM. As a new research approach, Chinmedomics is the best method to fit the holistic concept of TCM, and it can not only interpret the essence of syndrome but also elucidate the scientific connotation of Chinese medical formulae.

Objective To evaluate the variance and the concordance between the tumor length measured by CT scans and that measured by surgical specimens in esophageal carcinoma. Methods Fiftytwo surgical specimens of the esophageal carcinoma were made into pathological giant section.The shrinkage ratio of tumor was calculated by comparing the length of the specimen fixed by formalin for 24 h and that measured during the operation.One hundred and thirty-seven patients with esophageal carcinoma underwent spiral CT scan before the surgery,and the length of the gross tumor volume was obtained.After the tumor length of the fixed specimen had been measured,the real tumor length in situ was calculated using the shrinkage ratio.Then the variance and the concordance between the tumor length in CT scans and that in situ were compared.Results The mean shrinkage ratio was 90%±10%.The mean tumor length in CT scans was longer than that in situ(5.8 am±2.4 cm vs 4.1 cm±1.8 cm,P=9.68,P=0.000).The concordance of the length measured by the two methods was 40.9%(56/137). Conclusions A certain variance existed between the tumor length in CT images and that computed from surgical specimen in esophageal carcinoma.The results of esophagography and endoscopy should also be referred to delineate the gross tumor volume of esophageal carcinoma.

60 strains which have antimicrobial activity had been isolated from nutritious soil in China in the study.We have further selected 1 strain which product broad-spectrum antibiotics using agar well-diffusion method.The strain was identified Brevibacillus laterosporus after physiological biochemical characteristic experiments,sequencing of 16S rDNA and cluster analysis,named S62-9.
