ObjectTo study comparatively the transdermal absorption of baicalin per five kinds of animal skin. Methods Improved Franz-call was used for the transdermal study, and the transdermal speed constants of baicalin per five kinds of animal skin were compared. Results The transdermal speed constants of baicalin per skin of mice, hairless mice, rabbits, rats, human are (67.31?23.66), (78.35?3.29), (117.35?29.48), (86.25?7.55), and (84.43?11.27) ?g/(cm2?h), respectively. Conclusion The transdermal absorption of baicalin per skin of hairless mice is more similar to that of human skin.

Objective: To study the effects of compound transdermal enhancers on the transdermal kinetics of Baicalin. Methods: The uniform design was used for the selection of transdermal enhancers for the baicalin from various proportion of azone, propylene glycol and oleic acid. Results: The transdermal constant of baicalin is maxim when the proportion of is 6%,10%, and 0%, prespectively. Conclusion: The effects of compound transdermal enhancers is better than that of single one.

Autoimmune hepatitis (AIH) is the first liver disease which has proved responsive to gluc()orticoids,and the standard therapeutic method is hormone combined with azathioprine.Given that some patients fail to reach the standard of immunosuppressive therapy,and the long-term use of immunosuppressive therapy has many adverse effects,it is necessary to reasonably use anti-inflammatory and liver-protecting drugs to minimize the dose of immunosuppressants,control liver inflammation,reduce the damage of liver cells,and delay the progression of the disease.This paper reviews the advances in the application of anti-inflammatory and liver-protecting drugs in the treatment of AIH,in order to help clinicians make rational decisions.

OBJECTIVE:To study the kinetics of percutaneous permeability of baicalin in nude mice.METHODS:The transdermal constants of baicalin via nude mouse’s skin were determined,and the effects of stratum corneum on the kinetics studied.RESULTS:The kinetic equation of baicalin via nude mouse’s skin was Q=76.07T 1/2 -32.11,while the kinetic equa?tion of baicalin via nude mouse’s skin without stratum corneum was Q=134.25T 1/2 +29.07,and there was baicalin exuded from skin after detachment of patch.CONCLUSION:The kinetics of the patches is accord with the characteristics of frame?work type;the main barrier for baicalin permeance is stratum corneum and the skin without stratum corneum could store drugs.

Objective To evaluate the reliability and validity of the brief version of dysfunctional beliefs and attitudes about sleep(DBAS-16).Methods Participants were out-patients who with insomnia or insomnia comorbided depression disorder or anxiety disorder.All of them were assessed by DBAS-16,Pittsburgh sleep quality index (PSQI),self-rating depression scale (SDS),self-rating anxiety scale (SAS).30 of them were evaluated by DBAS-16 two weeks later.Results 230 patients were assessed,212 pieces of questionnaire with integral answers were collected,The Cronbach α Coefficient of DBAS-16 was 0.786,the Cronbach α coefficients of four subscales were 0.424-0.703.Split-half reliability coefficient of total score was 0.775,split-half reliability coefficient of four subscales were 0.424-0.719.Item-total correlation coefficients ranged from 0.602 to 0.283(all P＜0.05).The testretest reliability coefficient was 0.928,and coefficient of each subscales ranged from 0.709 to 0.907 (all P＜0.05).Confirmatory factor analysis was used to estimate the construct validity.The fit indices:x2/dfwas 1.623,the adjusted goodness of fit index (AGFI) was 0.882,root mean square error of approximation (RMSEA) was 0.054,incremental fit index (IFI)was 0.899,non-normed fit index (NNFI) was 0.871,comparative fit index (CFI) was 0.895.Total DBAS-16 score significantly correlated with PSQI(r=-0.311,P＜0.01),SDS(r=-0.192,P＜0.01),SAS(r=-0.162,P＜0.01).Conclusion The reliability and validity of the brief version of DBAS-16 are adequate.

Objective To observe the relationship between degree of venous injury and the indwelling time by injection of chemotherapy drugs with intravenous catheter system. Methods Totally 43 New Zealand rabbits were selected as the study sample. Among them, three rabbits were chosen by lot as a blank control, the others were evenly divided into two groups randomly. The veins at the edges of the two ears were taken out as the tested blood vessels for the infusion with intravenous catheter system. The two groups were injected respectively with physiological saline and chemotherapy drugs once daily, and then blocked with heparin salt water. After intraperitoneal anaesthesia, pathological sections were prepared by taking live samples from the ear vein where intravenous catheter system puncturing on the 2nd, 4th, 6th,8th and 10th day of transfusion. And inflammation and thrombosis in the vein had been observed under the light microscope. Results In the same indwelling time, the inflammatory response of the two groups was compared: no difference on the 2nd day; difference was seen on the 4th、6th and 8th day; but again no difference on the 10th day. Thrombosis compared: no difference on the 2nd, 4th day, but difference was seen on the 6th, 8th and 10th day. Conclusions Chemotherapy drugs has a strong irritant on blood vessels.The indwelling time should not be too long, generally advisable 2 days,even if no abnormal response is observed locally by the naked eye.

Objective To discuss the diagnostic value of high frequency ultrasound on lesions of knee traumas.Methods Ninty-eight cases with post-traumatic knee injuries were examined by high frequency ultrasound,and the characteristics of changing ultrasonogram were observed and comparing with surgical results and MR.Results Of the 98 cases with post-traumatic knee injuries,there were 57 cases with effusion and hematocele in knee joint,among which there were 41 cases with collateral ligaments and meniscus injuries,the diagnostic coincidence rate was 93.3% in tendon tear and complete tendon fracture(compared with MR),91.7% in partial and complete muscle tear(compared with MR),67.7% and 71.4% in collateral ligaments and meniscus injuries(compared with surgical results).Conclusions High frequency ultrasound can be used as a conventional imaging examination method for post-traumatic knee injuries.

Aim To investigate the expression of phosphorylated JNK1/JNK2 and the protection of 11,12-EET in ischemic and reperfusion rat heart.Method The expression of JNK1/JNK2 was detected with western blot method and the changing of heart function during ischemia/reperfusion process was observed in different groups. Results The cardiac function (+dp/dt_(max)%,-dp/dt_(max)% and LVDP)of reperfusion periods(30 min) apparently decreased in ischemia/reperfusion (I/R) group contrasted with Sham group, short ischemia(SI)+I/R group and EET+I/R group,and the expression of phosphorylated JNK1/JNK2 increased in I/R group contrasted with nromal group,Sham group and EET+I/R group.Conclusion The myocardial protection of 11,12-EET ( 6.24?10~(-8) mol?L~(-1)) is able to inhibit the expression of phosphorylated JNK1/JNK2.
