OBJECTIVETo observe the regulatory effects of electroacupuncture with different acupoints combinations on blood lipid and atherosclerosis index (AI) in rats with hyperlipemia, so as to make a preliminary screening for the optimal acupoints combination for hyperlipemia.

METHODSOne hundred and five clean-grade SD male rats were randomly divided into 9 groups, including a normal group, a model group, a Quchi group, a Zhongwan group, a Fenglong group, a Quchi+Zhongwan group, a Quchi+Fenglong group, a Zhongwan+Fenglong group and a Quchi+Zhongwan+Fenglong group (three acupoints group), 17 rats in the normal group and 11 rats in the rest groups. The normal group was fed with normal diet, while the rest groups were fed with high-fat diet for 3 weeks to prepare the hyperlipemia model. All the rats were given unlimited water. After the establishment of model, the normal group was fed freely without any treatment; the model group was bundled and immobilized everyday; the rest groups were bundled, immobilized and treated with electroacupuncture at corresponding acupoints with disperse-dense wave, 20 min per time, once a day. After 4 weeks, the blood examples were collected from abdominal aorta to measure the total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C), and analyzed the AI in each group.

RESULTSAfter the treatment, TC, TG, HDL-C, LDL-C and AI in each acupuncture group were all lower than those in the model group (P<0.05, P<0.01). Compared with single acupoint group and the Quchi+Zhongwan group, the content of TC in the three acupoints group was lower (P<0.01). The differences of content of TG among each acupuncture group were not significant (all P>0.05). Compared with the rest 6 acupuncture groups, the content of HDL-C and AI in the three acupoints group were significantly different (all P<0.05). The content of LDL-C in the three acupoints group was decreased as compared with the Quchi group and the Zhong-wan group.

CONCLUSIONThe electroacupuncture at "Quchi" (LI 11), "Zhongwan" (CV 12) and "Fenglong" (ST 40) has more advantages on regulating the content of HDL-C and LDL-C as well as improving AI in hyperlipemia rats, and it has superior effects on blood lipid metabolism.

This study was purposed to characterize the genomic distribution of the binding sites for AML1-ETO fusion protein on chromosome 2, 9 and 19, and to further gain insights into the characteristics of transcriptional regulation by AML1-ETO in acute myeloid leukemia so as to provide theoretical basis for the development of targeted therapy and optimization for treatment. Chromatin immunoprecipitation (ChIP) coupled with high density tiling arrays (chip), also known as ChIP-chip, was utilized in this study. ChIP-DNA enriched by an anti-ETO antibody and total genomic DNA of Kasumi cells were hybridized to tiling arrays, tiled through chromosome 2, 9 and 19. The ChIP enriched regions were identified using a model based analytical tool (MAT). Genomic distribution of the ChIP regions was analyzed using publicly available CEAS web server. The Gene Ontology (GO) enrichment analysis was performed to excavated the biological significance. The results indicated that a total of 588 enriched regions were identified on chromosome 2, 9 and 19 by the anti-ETO antibody. A number of the identified regions were located within enhancers (48.86%) or introns (37.35%), much smaller fractions were within proximal promoters (5.96%) or exons (5.49%). Functional enrichment analysis showed that cell proliferation and signal transduction biological pathways were enriched in potential genes of AML-ETO. It is concluded that half of the AML1-ETO binding sites are located within known transcriptional regulatory regions (promoter, 5' UTR and enhancer), while almost another half were within the sequences which were not previously reported as regulatory regions. The potential target molecular network of AML1-ETO is involved in several essential biological processes.

Alveolar echinococcosis is a zoonotic parasitic disease caused by an infection with Echinococcosis multilocularis.The liver is the primary organ of alveolar echinococcosis.Alveolar echinococcosis is usually characterized by invasive growth and consequently iscalled"parasitic cancer."Resection of radical lesions is a preferred and effective treatment for hepatic alveolar echinococcosis.End-stage hepatic alveolar echinococcosis often occurs with parasiticcirrhosis,such as secondary biliary cirrhosis,congestive liver cirrhosis or Budd-Chiari syndrome.Few studies have examined hepatic multilocular echinococcosis leading to cirrhosis.This article reviews the aspects of hepatic alveolar echinococcosis involving the invasion of important blood vessels and bile ducts,thereby leading to secondary biliary cirrhosis and congestive liver cirrhosis caused by hepatic alveolar echinococcosis.

OBJECTIVENoncystic fibrosis (non-CF) bronchiectasis remains as a common health problem in Asia. Pathogens' distribution in airways of patients with non-CF bronchiectasis is important for doctors to make right decision.

DATA SOURCESWe performed this systematic review on the English language literatures from 1966 to July 2014, using various search terms included "pathogens" or "bacteria" or "microbiology" and "bronchiectasis" or "non-cystic fibrosis bronchiectasis" or "non-CF bronchiectasis" or "NCFB."

STUDY SELECTIONWe included studies of patients with the confirmed non-CF bronchiectasis for which culture methods were required to sputum or bronchoalveolar lavage fluid (BALF). Weighted mean isolation rates for Haemophilus influenzae, Pseudomonas aeruginosa, Streptococcus pneumoniae, Stapylococcus aureus, Moxarella catarrhails were compared according to different methodology.

RESULTSThe total mean bacterial culture positive rates were 63%. For studies using sputum samples, the mean positive culture rates were 74%. For studies using BALF alone or BALF and sputum, it was 48%. The distributions of main bacterial strains were 29% for H. influenzae, 28% for P. aeruginosa, 11% for S. pneumoniae, 12% for S. aureus, and 8% for M. catarrhails with methodology of sputum. Meanwhile, the bacterial distributions were 37% for H. influenzae, 8% for P. aeruginosa, 14% for S. pneumoniae, 5% for S. aureus, and 10% for M. catarrhails with methodology of BALF alone or BALF and sputum. Analysis of the effect of different methodology on the isolation rates revealed some statistically significant differences.

CONCLUSIONSH. influenzae accounted for the highest percentage in different methodology. Our results suggested that the total positive culture rates and the proportion of P. aeruginosa from sputum and BALF specimens had significant differences, which can be used in further appropriate recommendations for the treatment of non-CF bronchiectasis.

BACKGROUND: Studies have shown that bone marrow mesenchymal stem cell (BMSC) transplantation can effectively improve cardiac function after myocardial infarction. However, few reports have been issued on myocardial electrophysiology after BMSCs transplantation. OBJECTIVE: To observe the effects of BMSCs transplantation on voltage-gated K+channel protein and myocardial infarction-related cytokines, thereby providing basic evidence for further exploration on the mechanism underlying arrhythmia in myocardial infarction due to BMSCs transplantation. METHODS: Forty male Wistar rats, SPF grade, were randomly divided into four groups: sham group, model group, cell culture medium group and BMSCs group. The myocardial infarction model was created in rats by permanent ligation of the left descending coronary artery. At 15-20 minutes after surgery, BMSCs (100 μL, 1×106) or cell culture medium (100 μL) was injected at four sites in the peri-infarct zone. Four weeks after cell therapy, cardiac samples were taken, the pathological morphology of the infarcted myocardium was observed by hematoxylin-eosin staining, and the infarct size was calculated; the expression levels of voltage-gated K+channel proteins Kv1.2 and Kv1.5 and cardiac troponin T (cTnT) were measured by western blot assay; and the expression levels of apoptotic factor (Caspase-3), autophagy factor (Bcl-2), nitric oxide and superoxide dismutase were tested by immunohistochemistry. RESULTS AND CONCLUSION: Compared with the model group and cell culture medium group, the infarct size decreased in the BMSCs group (P < 0.05); the expression levels of cTnT, Kv1.5 and superoxide dismutase increased (P < 0.05), and the expression levels of Caspase-3, Bcl-2 and Kv1.2 decreased (P < 0.05) in the BMSCs group. In summary, BMSCs transplantation can promote the expression of voltage-gated K+channel proteins, and improve anti-oxidation capacity of the myocardium and decrease apoptosis and autophagy.

Conclusion： DSA is not only a safe and effective measure for diagnosis and therapy, but also effective in differential diagnosis of space occupying lesions. Preoperative selective embolization of tumor supplying arteries can reduce operative blood loss.

OBJECTIVETo explore the relationship between polymorphisms of FAS and FASL genes and genetic susceptibility of silicosis.

METHODSA case-control study was conducted. The case group was 183 male patients with silicosis and the control group was 111 male silica-exposed but without silicosis miners. Data on total dust concentrations was collected to estimate cumulative total dust exposure (CTE) of each subject and each person's characteristics and work history were obtained from questionnaire. Polymerase chain reaction re-strained fragment length polymorphism technique (PCR-RFLP) was applied to detect the single nucleotide polymorphisms (SNPs) of FAS-1377, FAS-670 and FASL-844. Associations between polymorphisms and risk of silicosis and stages, interactions between polymorphisms, between polymorphisms and CTE and smoking and haplotypes were analyzed.

RESULTSThere were no differences in the FAS-1377, FAS-670 and FASL-844 genotypes between the case group and the control group (P > 0.05). No association was observed between FAS-1377, FAS-670 and FASL-844 polymorphisms and silicosis and stages (P > 0.05). The frequencies of FAS-1377G/-670G haplotype in the cases (9.6%) were higher than those in the controls (3.6%) (P < 0.05). No interactions between the polymorphisms of different genes, the gene polymorphism and the total accumulative total dust, the gene polymorphism and smoking were observed (P > 0.05).

CONCLUSIONFAS-1377, FAS-670 and FASL-844 polymorphisms are not susceptible factors of silicosis. The FAS-1377G/-670G haplotype might be a susceptibility marker of silicosis.
