AIM: To optimize the microemulsion containing tetramethylpyrazine phosphate in order to increase its transdermal delivery in vitro. METHODS: Pseudo-ternary phase diagrams were prepared to obtain the microemulsion areas at different ratio of surfactant to cosurfactant.In these areas,the formulation of microemulsion was optimized with four dimension simplex lattice method and the optimization equation was constructed,the accuracy of which was tested.With aid of SOLVER subprogram,the maximal value of transdermal flux and the formular of optimization microemulsion were calculated according to the equation.The diameter and stability of optimization microemulsion were tested. RESULTS: The experiment values from simplex lattice system were close to that of the predicted value from the equation.And the transdermal flux in vitro of optimized formular was 13.89 ?g/cm~(2)?h,It is mean diameter of 12.5 nm,and stable in six months. CONCLUSION: The optimization equation can predict transdermal flux of microemulsion system.The drug transdermal flux of the optimization formular improves significantly.That is stable in six months at mild temperature.

Objective:To observe the efficacy of different forms of triamcinolone acetonide( TA) in the treatment of buccal erosive oral lichen planus (EOLP). Methods:120 EOLP patients were randomly divided into 4 groups(n=30) and treated with Kangfuxin mouth-wash followed by topical ointment of( TA) , TA injection, TA mouth-wash and only Kangfuxin mouth-wash only, respectively. Before treatment, 1, 2 and 4 weeks after treatment, the pain (VAS score) and erosion area were measured, the effects were compared among groups. Results:The VAS scores of A, B and C groups were significantly lower than those of the control group after 1, 2 and 4 week treatment, and the total effective rate was significantly higher than that of the control group, respectively(P<0. 05). The VAS score was lower and total effective rate was higher in group A and group B than those in group C(P<0. 05), but there was no statistically sig-nificant difference between group A and B(P>0. 05). The average erosion area of group A and B was significantly smaller than that of the control group after 1, 2 and 4 week treatment(P<0. 05). There was no significant difference between group C and the control group after 1 and 2 week treatment(P>0. 05), but 4 weeks after treatment, the average area of erosion of group C was significantly smaller than that of the control group(P<0. 05). Conclusion:Triamcinolone acetonide is effective in the treatment of OLP and the oral oint-ment form is safe and convenient for OLP treatment.

Immunological imbalance is the foundation for the development of liver damage or fibrosis.Therefore,the treatment of liver disea-ses not only relies on regenerative medicine for cellular replacement,but also depends on immunoregulation.The immunological basis of liver injury and repair,the immunological basis of multipotent stem cells for allograft,and the research advances in the immunoregulatory effect of stem cells in the treatment of liver diseases demonstrated that multipotent stem cells,especially mesenchymal stem cells,have low immuno-genicity and cause immunosuppression,with the immunological basis of allograft;in addition,they can improve the local immune microenvi-ronment of the liver by immunoregulation to reduce the liver injury caused by immune response.It is suggested that multipotent stem cells, which meet the requirements of cellular replacement and immunoregulation in the liver,will become an ideal treatment of liver diseases.

The paper introduces using MedlineR to carry out data mining from Medline, for observing the gene relation, and using Pajek to realize the visualization of the results. Practice proofs that MedlineR could help researchers come up with assumptions in the field that they are interested in, and get a visual fingerprint. These results are the bases to go to more complex literature data mining and an important supplementary to experimental methods.

Objective: To study the morphological changes of erythrocytes in hyperl ipemia. Methods: Wistar rats used were divided into normal control group (NC) an d hyp erlipemia group (HL, fed with high lipid diets). The morphological changes of er ythrocytes were observed by SEM, and classified and counted. Results: Compared with NC,percentage of normal erythrocytes in HL were decreased from 76.4 % to 45.7%. The percentage of echinocytes, spherostomatocytes and target cells w ere increased from 4%, 2.2%, 1.5% to 17.3%, 10.4%, 5.8% respectively. The nu mber of ridged cells and abnormal cells was a little increased.Conclusion: The number of abnormal erythrocytes was significantly increased in h yperlipemia.

Obiective To discuss influence of psychological intervention on compliance improvement of patients with liver cirrhosis.Methods Patients with liver cirrhosis(100 cases)were divided in to the experimental group and the control group with 50 cases in each group.The control group received routine nursing.The experimental group and their family members were given systemic psychological in tervention by responsibility nudes.The treatment effect after nursing and intervention in the two groups was compared.Results The compliance of the experimental group was better than that of the control group,P＜0.05,which had statistical difference.Conclusions Implementation of psychological intervention shows significant effect on compliance improvement of patients with liver cirrhosis.
