OBJECTIVETo evaluate the effects of Yili dark bee propolis on the main cariogenic biofilm and mechanisms.
METHODSSusceptibilities to the ethanolic extract of propolis against Streptococcus mutans (S. mutans), Streptococcus sobrinus (S. sobrinus), Streptococcus sanguis (S. sanguis), Actinomyces viscosus (A. viscosus), and Actinomyces naeslundii (A. naeslundii) were analyzed by crystal violet stain method to determine the minimum biofilm eradication concentration (MBEC). The biofilm was initially cultivated for 24 h. Subsequently, the propolis groups with different concentration MBEC and initial pH 7.0 were cultured for 24 h. Moreover, the pH value was measured to evaluate the acid-producing ability of the tested plaque biofilm. The effects of propolis on the insoluble extracellular polysaccharide synthesis of S. mutans biofilm were evaluated by anthrone method.
RESULTSThe MBEC of Yili propolis on S. mutans, S. sobrinus, S. sanguis, A. viscosus, and A. naeslundii were 6.25, 1.56, 3.13, 0.78, and 0.78 mg.mL-1, respectively. Propolis could decrease the ΔpH of the tested plaque biofilm, and the differences between the control and propolis groups were statistically significant (P<0.05). At MBEC, propolis could reduce the ability of S. mutans in synthesizing insoluble extracellular polysaccharides.
CONCLUSIONYili propolis demonstrate remarkable eradicative effects on the cariogenic plaque biofilm, showing inhibition of the synthesis of biofilm-produced acids and insoluble extracellular polysaccharides.

The aim of this study is to investigate the protection effect of tanshinone IIA (Tan) against triptolide (TP)-induced liver injury and the mechanisms involved. Acute liver injury was induced by intraperitoneal injection of TP (1 mg x kg(-1)) in mice. The activities of AST, ALT and LDH in serum and the levels of GSH, GST, GSH-PX, SOD, CAT and MDA in liver tissue were detected. The histopathological changes of liver tissues were observed after HE staining. Nrf2 translocation in liver tissue was detected by Western blotting, and real-time PCR was used to measure the expression levels of GCLC, NQO1 and HO-1 mRNA. The results showed that pretreatment with Tan significantly prevented the TP induced liver injury as indicated by reducing the activities of AST, ALT and LDH (P < 0.01). Tan pretreatment also prevented TP-induced oxidative stress in the mice liver by inhibiting MDA and restoring the levels of GSH, GST, SOD and CAT (P < 0.05). Parallel to these changes, pretreatment with Tan could attenuate histopathologic changes induced by TP. Furthermore, the results indicated that Tan pretreatment caused nuclear accumulation of Nrf2 as well as induction of mRNA expression of antioxidant response element (ARE)-driven genes such as GCLC, NQO1 and HO-1. These results indicated that Tan could protect against TP-induced acute liver injury via the activation of Nrf2/ARE pathway.

Objective To present and summarize the data concerning the diagnosis and treatment of popliteal aneurysm in our hospital. Methods The data of popliteal aneurysm in our hospital from 1975 to 2004 were reviewed and analyzed. Eleven patients with 11 diseased limbs were treated, including 8 males and 3 females, age from 21 years to 64 years 〔(48.54?13.66) years〕. The combined diseases include syphilis, rheumatic heart disease and chronic obstructire pulmonary disease etc. Ten patients received operations, including endoaneurysmorrhaphy (n=4) and graft bypass after aneurysmal resection (n=6), through posterior approach (n=7) or medial approach (n=3). One patient, combined with advanced syphilis and heart failure, received conservative treatment because of his poor general condition. Results The common clinical manifestations included popliteal pulsating mass, claudication, difficulty in extension of the knee, pain etc. Acute ischemia occurred in 3 limbs. The diameter of popliteal aneurysms varied from 4-13 cm 〔(6.73?2.69) cm〕. There were 3 (27.3) cases of ruptured aneurysms whose diameters were 7 cm, 7 cm and 11 cm respectively. Special examinations included arteriography and Doppler sonography. Pathological results of these patients were pseudoaneurysm (n=3), syphilitic aneurysm (n=3) and atherosclerotic aneurysm (n=4). Two patients were not followed up, and postoperative follow up of the other 8 patients ranged from 18 months to 30 years. In the group of endoaneurysmorrhaphy, postoperative gangrene of the affected limb occurred in one patient, and above-knee amputation was performed. One patient suffered from intermittent claudication in the group of endoaneurysmorrhaphy and of graft bypass respectively. No manifestations of limb ischemia were found in the other 5 patients during the time of follow up. Conclusion General utilization of Doppler sonography in screening high risk patients might be helpful to detect popliteal aneurysm. For symptomatic popliteal aneurysm or asymptomatic popliteal aneurysm with diameter larger than 3 cm, operation is indicated. Asymptomatic popliteal aneurysms no more than 3 cm in diameter could be monitored with care.

?Advances in genome-wide analysis have revealed that up to 90%of the human genome is transcribed.However, only approximately 1% of RNA transcripts encode proteins, and the remaining transcripts are noncoding RNAs.Noncoding RNAs can be roughly divided into small noncoding RNAs (<200nt ) and long noncoding RNAs ( LncRNAs, >200nt ). Small noncoding RNAs include microRNAs, transfer RNAs and small nucleolar RNAs, whereas the long noncoding RNAs comprise ribosomal RNA, natural antisense transcripts, etc. Although the biosynthesis and biological activities of microRNAs are well studied through bioinformatics and active biological molecules analysis, the understanding of LncRNAs on these aspects is still limited.LncRNAs play multiple roles in regulating gene transcription and translation, and epigenetics.Aberrant LncRNAs expression can occur in various pathological processes and significantly related to the pathogenesis or poor prognosis of ophthalmological diseases. In this review, we will focus on the characteristics and regulatory functions of LncRNAs that are commonly associated with ophthalmological diseases.
