Background Trachoma is a common infectious eye disease,and its incidence is associated with region,economy and sanitary condition.To survey the prevalence status of an area is very important for the prevention and treatment of trachoma.Objective Aim of this study was to survey the prevalence of trachoma in primary and secondary school students of Chifeng Keshiketengqi,and to investigate the relationship between the prevalence of trachoma with age,gender,ethnicity and living environment.Methods This was a cross-sectional study.According to cluster random sampling method,2067 students were drawn from 10 primary and secondary schools,including 1061male and 1006 female.The age of students ranged from 6 to 17 years old,with the average age (12.53 ± 2.31)years.In the taken samples,Han students were 1768,and Mongolian students were 299;the agricultural and pastoral students were 1209,and the urban students were 858.The general life factors associated with trachoma were surveyed by questionnaire.Trachoma was diagnosed and graded based to 1987 WHO Simplified Trachoma Grading Standards.Eye examinations included visual inspection,eyelids,conjunctiva and cornea neovascularization under the slit lamp microscope,and the clinical data were recorded and collected.The results were statistically analyzed by SPSS13.0 software.Results According to the sampling proportion of 10.05%,2153 students were included and 2067 students participated in this study with the response rate 96%.Trachoma was diagnosed in 972 students with a morbidity 47.0%.The prevalence rate of trachoma was increased with the ageing,and a statistically significant difference was seen among the 6-8 years group,9-11 years group,12-14 years group and 15-17 years group (x2 =11.043,P =0.011),and the prevalence of trachomatous infiltration was significantly higher than that of trachomatous folliele (x2=11.493,P<0.05).The prevalence rate of trachoma in Han and Mongolian students was 45.8% and 54.5%,showing a significant difference between them (x2 =6.228,P =0.013).In addition,statistically significant differences also were found in the prevalence rate of trachoma between the pastoral areas students and urban students (56.1% vs.39.7%,x2=30.226,P =0.000),but no significant difference was seen between male and female (47.0% vs.46.9%,x2 =0.000,P =0.995).Conclusions The trachoma prevalence rate is relatively higher in the primary and secondary students in Chifeng Keshiketeng.These results offer a basis for the prevention and treatment of trachoma.

The marine biological source of mineral drugs recorded in Chinese Pharmacopoeia (2010 version) mainly including pearl, nacre, clam shell, common oyster shell, ark shell, cuttle bone, and sea-ear shell are widely used in clinical. Calcium carbonate and a small amount of protein are the main components in this type of drugs. In this paper, a systematical and comparable study were carried out by determination of calcium carbonate by EDTA titration method, the crystal of calcium carbonate by X-Ray powder diffraction and the total amino acids (TAAs) of the hydrolyzed samples by ultraviolet spectrophotometry method. As a result, the crystal structure is calcite for common oyster shell, mixture of calcite and aragonite for nacre and sea-ear shell, aragonite for the other drugs. The content of calcium carbonate ranged from 86% to 96%. Cuttle bone has the highest amount of TAAs among the seven drugs which reached 1.7% while clam shell has the lowest content of 0.16% on average. In conclusion, an effective method was developed for the quality control of marine mineral drugs by comprehensive analysis of calcium carbonate and TAAs in the seven marine mineral drugs.

Objective ① To Screen for the miRNAs differently expressed in the peripheral blood mono-nuclear cells (PBMCs) of rheumatoid arthritis (RA) by microarray experiments.② To further evaluate the expression of miR-155 in PBMCs of RA.③ To determine the relevance between the expression of miR-155 and clinical as well as laboratory features.④ To test whether inflammatory mediators can induce miR-155 expression in PBMCs of RA.Methods ① Total RNA was isolated from peripheral blood mononuclear cells obtained from 5 patients of RA and 5 normal controls.Expression profiling of miRNAs was performed in a microarray analysis.② MiR-155 was identified for further study by stem-loop real-time RT-PCR based on SYBR-Green.PBMC from 26 patients of RA and 23 normal controls were collected.③ Association between miR-155 and the clinical and laboratory features of RA was evaluated.④Induction of miR-155 following stimulation with TNF-α, IFN-γ and LPS of cultures of RA PBMCs was examined by real-time RT-PCR.Statistical analysis was done with student's t test, paired t test, and ANOVA, Spearman correlation.Results ① Expression profiling of miRNAs revealed significant differential expression of 14 miRNAs, of which signal intensity changed over two times.MiR-155 was up-regulated in PBMCs of RA than in normal controls (t=9.218, P=0.001).② The expression level of miR-155 had a positive correlation with serum CRP level (r=0.57, P=0.002).③ Expression of miR-155 was markedly up-regulated in PBMCs of RA after stimulated with TNF-α,IFN-γ and LPS, especially with TNF-α.Conclusions The expression of miR-155 is induced by stimulating with TNF-α, IFN-γ and LPS.MiR-155 may be a regulator in RA pathogenesis.Further studies are required to elucidate the function of miR-155.

Objective To screen for the miR-155 expression in synovial fibroblasts of rheumatoid arthritis (RASFs) and osteoarthritis (OASFs) and to evaluate the function of miR-155 on RASFs and its possible target mRNAs. Methods The expression levels of miR-155 in RASFs and OASFs were detected by real-time PCR. MiR-155 mimic and miR-155 inhibitor, as well as scrambled control were transfected into cultured RASFs by Lipofectamine 2000. Forty-eight hours later, MMP-3 levels in the cell culture supernatant were detected by ELISA and fibroblast proliferation was assayed by 3H -TdR incorporation test. Fibroblast invasive ability was tested by transwell system. IKBKE which previously identified as actual target of miR-155 was examined by real-time PCR. Comparisons between groups were performed with t test or one-way ANOVA analysis. Results It was shown that miR-155 was up-regulated in RASFs (1.79 ±1.94) and it was higher than that in OASFst (0.11±0.17), P<0.05]. Up-regulation of miR-155 could decrease MMP-3 levels (P<0.05). The proliferation and invasion of RASFs transfected with miR-155 were both evidently suppressed (P<0.05), while reducing the endogenous miR-155 could significantly enhance RASF proliferation (P<0.05). The expression of IKBKE of RASFs transfected with miR-155 was obviously down-regulated compared to those transfected with the scrambled control (P<0.05). Conclusion miR-155 is up-regulated in RASFs which may be a protective factor against the inflammatory effect, at least partially by attenuating the expression of IKBKK.

10. Study on quality markers of ginseng acting on heart failure based on TCMIP V2.0
Chinese Traditional and Herbal Drugs 2019;50(19):4628-4633
Objective: To predict the possible quality markers of ginseng in the treatment of heart failure. Methods: The ginseng chemical information was used to predict its putative targets related to heart failure by TCMIP V2.0 and the protein-protein interaction (PPI) network was constructed. The key targets of drug intervention on heart failure were enriched. The interaction network of chemical components-key targets-pathways was constructed to obtain the main components acting on these key targets, which are related to drug efficacy. According to the five principles of quality markers identification, we analyzed the quality markers of ginseng in the treatment of heart failure. Results: A total of 63 key targets were obtained for ginseng in the treatment of heart failure, including 63 putative drug targets and two targets related to disease. ATP1A1 and ADCY2 are the common targets associated with the drug and disease. The common targets of ATP1A1 and ADCY2 may be the key targets of drug acting on disease. The main components of ginseng acting on these common targets were screened out, and then we have determined the possible quality markers of ginseng for the treatment of heart failure based on the five principles of quality markers. Conclusion: We obtained the possible quality markers of ginseng in the treatment of heart failure, including ginsenoside Rg1, ginsenoside Re, ginsenoside Rf, and ginsenoside Rb2, which provided the basis for our deeper research of ginseng in the treatment of heart failure.
