Objective:To investigate and evaluate the anti-tumor activity of hydroxychloroquine ( HCQ) in vitro. Methods:CCK-8 assay was applied to detect the inhibitory effect of HCQ at different concentrations(4. 78, 9. 55, 19. 10, 38. 20,76. 40 μg?ml-1 ) on A549 cells, HepG2 cells, HT-29 cells, K562 cells, Hela cells and B16 cells. Absorbance was detected by a microplate reader, and then the inhibitory rate of the tumor cells and the IC50 was calculated. Results:Compared with those of the negative control group, the inhibitory rates of HCQ at different concentrations against the six tumor cells were all increased significantly in a dose-dependent manner (P<0. 01). The inhibitory rates of the tumor cells were all above 60% when the concentration reached 38. 20μg?ml-1. The IC50 was 26. 70(A549), 27. 47(HepG2), 5. 72(HT-29), 14. 03(K562), 20. 21(Hela) and 13. 62(B16) μg?ml-1, respectively. Conclusion:HCQ shows anti-tumor activity on several cancer cells in vitro. There may be a good application prospect for HCQ in the treatment of colorectal cancer, liver cancer, cervical cancer, melanoma and leukemia.

OBJECTIVETo investigated the genetic polymorphism of the isolated strains using ribotyping method.

METHODSOne hundred twenty-two strains of V. cholerae O139 isolated from different areas of China from 1993 to 1999 were selected and characterized with ribotyping, including 16s rDNA and 23s rDNA probes.

RESULTSOne hundred twenty-two strains were differentiated into 10 different ribotypes (RT1-RT10) on the basis of rRNA gene probes hybridization (with Bgl I digestion), which consisted of 7 - 9 bands between 12 and 1.5 kb in size. RT1 and RT3, as two predominant ribotypes, comprised most number of the strains which spread to the extensive range. Nine strains, which are negative to ctxAB, zot and RS individually, belong to 4 special ribotypes. The dendrogram revealing genetic relationship among different clones of V. cholerae O139 showed that the clones belonging to RT1 and RT2 had genetic similarity on high degree, although they were isolated from different regions. The two predominant ribotypes (RT1 and RT3) were distant in genetic relationship.

CONCLUSIONResults showed the clonal diversity and the wide area distribution of V. cholerae O139 strains in China, suggesting the multiple origins of O139 epidemics.

Objective: To investigate the clinicopathologic characteristics of intractable epilepsy. Methods: Based on the classification criteria proposed by the International League Against Epilepsy (ILAE), a retrospective analysis of the pathological characteristics was done in 822 patients who underwent epilepsy surgery in Sanbo Brain Hospital, Capital Medical University, from June 2008 to December 2012. Results: The mean age of epilepsy onset was 9.9 years, mean duration of epilepsy was 11.9 years. Complex partial seizures were the main presenting features. Histopathological study showed 33 cases (4.01%) with mild forms of cortical malformations, 690 cases (83.94%) with focal cortical dysplasia (FCD) and 99 cases with others (including 39 pure hippocampal sclerosis, 20 cystosclerosis, 19 Sturge-Weber syndrome, 8 tuberous sclerosis complex, 6 without significant pathological changes, 5 gyral malformations and 2 hamartoma). Among the 690 FCD cases, 106 were FCD typeⅠ, 91 were FCD typeⅡ and 493 were FCDⅢ(Ⅲa: 160, Ⅲb: 106, Ⅲc: 26 and Ⅲd: 201). Conclusions FCDⅢd is the most common histopathological subtype causing intractable epilepsy, mainly due to focal hypoxia/ischemia in the perinatal period, which results in scarring of local brain tissue; this is followed by other isolated forms of FCD (FCDⅠand FCDⅡ), and then FCD Ⅲa and FCD Ⅲb. The reason to distinguish isolated forms of FCD (types Ⅰ and Ⅱ) from FCD Ⅲ and to subclassify FCD Ⅲ is to allow better definition of cortical dyslamination. Therefore, the pathogenic factors of intractable epilepsy can be grouped in greater details, and facilitate the diagnosis and potential curative treatment of intractable epilepsy.

Objective:To analyze the characteristics of prescription about Lingnan Traditional Chinese Medicine (TCM) masters for Biqiu treatment based on data mining, so as to provide reference for the clinical practice and patent drug research and development of rhinorrhea in Lingnan district.Methods:By searching journal documents and medical records in CNKI, VIP, Wanfang, Chinese BioMedical Database (SinoMed) and Duxiu Data Retrieval Platform, we selected the articles and famous TCM medical records that met the criteria on the TCM medical rules of treating Biqiu. We screened database in strict accordance with inclusion and exclusion criteria and extracted prescription information from medical cases. The software Ancient and Modern Consilia Cloud Platform (V 1.5) was used for data mining analysis and medical case standardization, and SPSS Clementine 12.0 software were used to conduct frequency statistics, association analysis and cluster analysis of drugs in medical cases. Results:A total of 31 articles and 42 medical cases including 73 prescriptions were screened. The frequency results showed that there were 40 kinds of high frequency TCMs (frequency more than 5), mainly including drugs for benefiting the qi and strengthening the spleen, medicine to relieve cold and promote nasal passages, which was the same as the frequency statistics of the effects of herbal medicine. Seven drug groups were obtained by cluster analysis. The results of rule analysis showed that 16 association rules for drug pairs and 18 association rules for 3 TCMs pairs were obtained.Conclusions:While treating allergic rhinitis, Lingnan medical doctors focus on tonifying spleen qi, dispersing wind and cold, and promoting the nasal passages, which reflect the treatment theory of cultivating earth and generating gold, and attacking and tonifying. Lingnan medical doctors commonly used Guangdong medicinal herbs, which have distinct regional characteristics. The data mining methods can comprehensively summarize and explore the potential rules of Lingnan prominent practitioners' treatment of allergic rhinitis, and provide reference for guiding the treatment of congested nose and congested nose in TCM.

Objective To investigate the effects of eicosanoic acid(C20DC)on the proliferation and migration of human retinal endothelial cells(HRECs)and its mechanism.Methods The optimal working concentration of C20DC in human retinal pigment epithelium 19(ARPE-19)cells and HRECs was determined as 30 mg·L-1 and 25 mg·L-1,respec-tively.HRECs were divided into the C20DC treatment group(HRECs treated with C20DC)and the control group[HRECs treated with dimethyl sulfoxide(DMSO)].The effects of C20DC on the migration and proliferation of HRECs were detec-ted by cell proliferation and migration experiments.The molecular docking method was used to simulate the binding ability of C20DC to peroxisome proliferator-activated receptor δ(PPARδ).ARPE-19 cells were divided into the C20DC+ARPE-19 group(ARPE-19 cells treated with C20DC)and the DMSO+ARPE-19 group(ARPE-19 cells treated with DMSO).The ex-pression levels of PPARδ and angiopoietin-like protein 4(ANGPTL4)in ARPE-19 cells and ANGPTL4 protein in HRECs were detected using Western blot.The ANGPTL4 protein expression levels in ARPE-19 cells and HRECs were quantitatively analyzed using enzyme-linked immunosorbent assay(ELISA).Results Compared with the control group,the prolifera-tion and migration of cells in the C20DC treatment group significantly increased(both P＜0.05),and C20DC could stably bind to PPAR8(binding energy:-7.20 kcal·mol-1).Western blot showed that the expression level of ANGPTL4 protein in the C20DC+ARPE-19 group was higher than that in the DMSO+ARPE-19 group,and the difference was statistically sig-nificant(P＜0.05);there was no statistically significant difference in the expression level of PPARδ receptor protein be-tween the two groups(P＞0.05).The expression level of ANGPTL4 protein in the C20DC treatment group was higher than that in the control group,and the difference was statistically significant(P＜0.05).ELISA quantitative analysis showed that the expression level of ANGPTL4 in the C20DC+ARPE-19 group was higher than that in the DMSO+ARPE-19 group(P＜0.001);the expression level of ANGPTL4 in the C20DC treatment group was higher than that in the control group,and the difference was statistically significant(P＜0.05).Conclusion C20DC can promote the expression of ANGPTL4 pro-tein by binding to PPARδ and thus increase the proliferation and migration of retinal related cells(HRECs and ARPE-19 cells).Its mechanism may be related to the increased angiogenesis in retinopathy of prematurity.
