AIM:To prepare O/W microemulsion formulation containing sinomenine and investigate the effect of different penetration enhancers on transermal delivery character of microemulsion in vitro. METHODS: The microemulsions were prepared and characterized using Zetasize potential/particle size analysis instrument.The stability tests were performed to evaluate the sinomenine microemulsions.Franz diffusion cell was adopted as the apparatus for in vitro transdermal test.Excised Wistar-rat abdomen skin was pretreated with penetration enhancers,such as menthol,borneol and isopropyl myristate. RESULTS: The average droplet size of the microemulsion was about(31.3 nm.)A high permeation rate of(32.238?1.13)?g/cm~(2)?h was showed in vitro.Ail the enhancers showed significant enhancement effect on the transdermal behavior of sinomenine microemulsion.2% borneol had the strongest effect in all. CONCLUSION: These results indicate that the studied microemulsion system with high permeation rate may be a promising vehicle for the transdermal delivery of sinomenine.Menthol,borneol and isopropyl myristate were found to be the proper penetration enhancers in the transdermal preparation.

Systemic lupus erythematosus (SLE) is a kind of complex autoimmune connective tissue disease involving multi-organ and multiple systems.And the cardiovascular complication is a major cause of mortality in SLE patients.The diagnosis and evaluation depend on imaging.As a non-invasive,simplicity and repeatability method,echocardiography plays a vital role in evaluating heart structure and function.The application of echocardiography in the SLE with cardiovascular complications were reviewed in this article.

ObjectiveTo investigate osteopontin (OPN) level in pulmonary tuberculosis and its clinical significance.MethodsThe level of serum OPN was determined in 80 pulmonary tuberculosis patients before anti-tuberculosis treatment[patients group,simple pulmonary tuberculosis with 60 cases (simple pulmonary tuberculosis group),pulmonary tuberculosis combined with tuberculous pleurisy with 20cases (pulmonary tuberculosis combined with tuberculous pleurisy group)],and compared with that of 30healthy persons (healthy control group) and 20 patients having received effective anti-tuberculosis treatment and followed-up for 6 months (followed-up group).At the same time,the clinical significance of OPN was studied by other commonly used clinical indicators of tuberculosis.ResultsThe level of serum OPN in patients group [(843.49 ±569.23) ng/L] was significantly higher than that in healthy control group [(352.50 ± 185.02) ng/L,P ＜0.05].The level of serum OPN after treatment in followed-up group were significantly decreased compared with those before treatment [(494.11 ±352.40) ng/L vs.(1106.60 ± 628.39) ng/L,P＜ 0.05 ] and there was no significant difference compared with those in healthy control group (P ＞ 0.05 ).The level of serum OPN in pulmonary tuberculosis combined with tuberculous pleurisy group [(1179.80 ±606.33) ng/L] was significantly higher than those in simple pulmonary tuberculosis group [(727.53 ±511.66) ng/L,P ＜0.05],and they were both higher than those in healthy control group [ ( 352.50 ± 185.02 ) ng/L,P ＜ 0.05 ].Therefore,for further additional subgroup analysis in simple pulmonary tuberculosis group,the level of serum OPN in patients with cavity[ ( 836.51 ± 549.80) ng/L ] was significantly higher than that without cavity [ (535.52 ± 375.95 ) ng/L,P ＜ 0.05 ],while the levels of serum OPN had no statistical difference between pulmonary lesion involved ＜ 3 leaf patients and ≥ 3 leaf patients,sputum mycobacterium tuberculosis positive patients and negative patients,mycoDot test results positive patients and negative patients,erythrocyte sedimentation rate elevated patients and normal patients,PPD strongly positive patients and non-strongly positive patients (P＞0.05).ConclusionsOPN activity is closely related with pulmonary tuberculosis.OPN can serve as a judge of pulmonary tuberculosis and the clinical indicators of disease outcome.The level of serum OPN and the severity of pulmonary tuberculosis have some correlations.

Epigenetics is defined as heritable changes in genc expression that are,unlike mutations,not attributable to alterations in the sequence of DNA.The predominant epigenetic mechanisms are DNA methylation,histone modification and microRNA.Exploring the precise roles of epigenetic factors on autoimmunity has become an active research area.Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disorder with a prevalence of approximately 0.5％ to 1.0％ worldwide.The mechanisms underlying the initiation and progression of RA are still not completely understood.In recent years,the epigenetics of RA have been widely investigated.Alterations in the modification of histones and DNA methylation are the two major epigenetic mechanisms that may potentially cause a breakdown of immune tolerance and the perpetuation of RA.These epigenetic changes may be ideal targets for new personalized treatments.

OBJECTIVE: To investigate the effect of nasal surgery alone for OSAHS using Meta-analysis. METHOD: The published articles were searched from PubMed, Chinese Biomedical Literature CD-ROM databases, China Academic Journals Full-text database. The quality of the searched original studies were assessed and the outcomes with the requirements were analyzed. RESULT: Nineteen articles and 621 cases were finally included, including 15 English literatures and 4 Chinese literatures. The results of Meta analysis showed that: (1)The weighted mean between pre-and postoperative AHI was no significantly difference [weighted mean difference (WMD) = 0. 11, 95% CI (-0. 02,0. 23), P>0. 05]. (2) The nasal surgery alone significantly reduced theEpworth sleepiness scale scores in thirteen studies [WMD=0. 94,95% CI (0. 62,1. 26), P<. 01]. CONCLUSION The meta-analyses show that nasal surgery alone can effectively improve the subjective clinical symptoms of patients with OSAHS. However, nasal surgery alone has a limited efficacy in treating OSAHS.
