1.Transdermal delivery character of sinomenine microemulsion
Chinese Traditional Patent Medicine 1992;0(08):-
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.

Chinese Journal of Medical Imaging Technology 2017;33(4):624-627
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.
3.Determination of serum osteopontin in pulmonary tuberculosis patients and its clinical significance
Chinese Journal of Postgraduates of Medicine 2012;35(1):36-39
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.
4.Research progress of the influence of alcohol on the local microenvironment of femoral head
Chinese Journal of Tissue Engineering Research 2017;21(7):1137-1142
BACKGROUND: The pathogenesis of alcoholic avascular necrosis remains unclear. OBJECTIVE: To introduce the physiological structure and pathologic changes induced by alcohol of the microenvironment of femoral head, and to review the research status of the influence of alcohol on the microenvironment of femoral head. METHODS: A computer-based online research of PubMed database for clinical and basic studyies concerning the effect alcohol on the microenvironment of femoral head published from 1990 to 2016. The pathological changes of alcoholic osteonecrosis of the femoral head were overviewed. RESULTS AND CONCLUSION: There are various theories about the pathogenesis of alcoholic osteonecrosis of thefemoral head, but the essence is the disturbance of blood circulation in femoral head, and long-term decrease in the nutrients and oxygen supplying of bone leading to bone degeneration and necrosis. Large-dose intake of alcohol will induce the imbalance of oxidation and anti-oxidation system, which dose harm to the microenvironment of femoral head. The change of oxygen supplying accelerates the necrosis of femoral head, the weakened differentiation of bone marrow mesenchymal stem cells into osteoblasts and the disturbance of bone resorption-formation imbalance finally result in the necrosis and collapse of femoral head. It is expected to provide a new therapeutic strategy for delaying or preventing the early femoral head necrosis by controlling the microenvironment of femoral head.
5.Meta analysis of nasal surgery alone for obstructive sleep apnea hypopnea syndrome.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2015;29(6):499-504
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.

6.Prevention and treatment of vitamin K deficiency in neonates and infants
Chinese Journal of Applied Clinical Pediatrics 2016;31(14):1059-1062
Vitamin K deficiency is a common problem in neonates and infants,vitamin K deficiency bleeding can be life threatening.There is still a high incidence of vitamin K deficiency even if the prevention by retrospective analysis a large number of the global data.In recent years,with the increase of premature infants,incidence is higher than before,China is the same trend.There is no recognized prevention and treatment measures,and less related research data.Therefore,to carry out related investigation,to provide the basis for clinical prevention and treatment are an urgent task.

Chinese Journal of Hospital Administration 1996;0(05):-
Objective To assess the effect of resident training in clinical skills on SARS prevention and treatment. Methods A survey was conducted by means of questionnaires on 101 residents of the authors' hospital who were at the forefront of the fight against SARS. Results Training in clinical skills assisted the residents to various degrees in SARS prevention and treatment. 100% of the residents surveyed held that the training was helpful, beneficial and assisted them in solving problems. Conclusion Training in clinical skills, which rendered the residents proficient in basic skills and more capable of clinical application of the skills, also enhanced their ability to handle emergent events in SARS prevention and treatment.
