AIM: To explore the effects of carbonizing temperature and time on HPLC fingerprints of Flos Sophorae for improving the processing technics of Flos Sophorae carbonized.METHODS: Samples were prepared by an oven for different time and at different temperatures,separately.Then the fingerprints of the samples were determined by HPLC,separately.According to the fingerprints of the crude drug,the differences between the fingerprints of the samples were compared. RESULTS: Heated for 30 min,there was no significant change of the fingerprints of the samples which were heated at 120(?C)-150(?C);there was a little change in the fingerprints when the samples were heated at 170(?C),but the significant change was observed when they were heated at 180(?C)-190(?C).The fingerprints showed the chemical constitutents were almost destroyed over 200(?C).Over 160(?C),the effects on the samples which were heated for 60 min were more obviously than on those which were heated for 30 min. CONCLUSION: According to the change of the fingerprints and in view of the efficient usage of the energy,Flos Sophorae carbonizing should be heated at 185(?C)?2 (?C) and for 30 min.

GlyoxalaseⅠthat presents in all human tissues detoxifies α-oxoaldehydes and prevents the formation of advanced glycation end products(AGEs).AGEs and their main precursor namely methylglyoxal(MG)produce cytotoxicity and have extensive relationship with diabetic complications.Therefore,to elevate glyoxalaseⅠactivity may be a new path to release such complications.

Objective To compare the effect of compound flumethasone ointment and clobetasol propionate cream on serum and skin lesion Th cell related indicators in patients with eczema. Methods 156 patients with chronic eczema were chosen. According to the type of topical drugs, they were divided into two groups: the flumethasone group and the clobetasol propionate group. The changes of eczema treatment effect, serum and skin lesions Th cell related indicators of the two groups were compared. Results After treatment, the serum interferon-γ (IFN-γ) of the flumethasone group was (27.57 ± 5.67) pg/mL, IL-2 was (36.51 ± 8.03) pg/mL and IL-4 was (26.37 ± 5.29) pg/mL, IL-10 was (25.38 ± 4.64) pg/mL and INF-γof skin lesions was (56.53 ± 21.81) pg/L , IL-2 was (51.69 ± 15.67) pg/L, IL-4 was (159.42 ± 25.64) pg/L and (139.62 ± 24.58) pg/L, significantly lower than those of clobetasol propionate group (P <0.05), but the clinical benefit rate (94.87%) was significantly higher than (80.77%) of clobetasol propionate group (P <0.05). Conclusion Compared with clobetasol propionate cream, the effect of compound flumetasone ointment is more effective in treating eczema, and its mechanism may regulate the expressions of Th cell related cytokines.

Objective To study inhibitory effect of serine protease activity by Ulinastatin in vitro .Methods Different chromogenic peptides were designed and synthesized.Highly sensitive fluorescence detection was performed to optimize the concentration of each serine proteases and their chromogenic substrates.Multi-point method was used for the calculation of half maximal inhibitory concentration of Ulinastatin .ResuIts Ulinastain could inhibit Polymorphonuclear leukocyte elastase ( PMNE ) and plasmin with IC50 lower than 100 U/mL.For factor Xa, and Kallikrein, the IC50 of Ulinastatin was higher than 1000U/mL.No thrombin IC50 could be calculated at the present experiments.ConcIusion Similar to Ulinastatin injection from Japan, domestic Ulinastatin shows the strongest inhibitory effects on PMNE among those serine proteases.As important references, this study gives reliable data for dose range of domestic Ulinastatin in anti-inflammation, coagulation/anti-coagulation and anti-shock therapy.

Objective To evaluate the efficacy and safety of hydroxychloroquine combined with butyli flufenamatum ointment and other drugs for the treatment of polymorphous light eruption (PLE).Methods A total of 48 patients with PLE were randomly and equally classified into group 1 and group 2.Both groups took hydroxychloroquine 200 mg twice a day and loratadine 10 mg per day for the initial 4 weeks,then took hydroxychloroquine 100 mg twice a day alone for another 4 weeks.Group 1 also topically applied butyli flufenamatum ointment twice a day during the 8 weeks,while group 2 applied mometasone furoate cream twice a day for the first 2 weeks followed by butyli flufenamatum ointment twice a day for another 6 weeks.Each treatment cycle lasted 2 weeks,and both groups received 4 cycles of treatment.Patients were evaluated for the response rate at the end of each cycle,and for the total symptom score and erythema score before and after the 8-week treatment.Statistical analysis was carried out using t test,chi-square test,Fisher's exact test and repeated-measures analysis of variance with the SPSS17.0 software.Results On day 14,28,42 and 56,the total score improved in 0,3,12 and 19 patients in group 1 respectively,and in 1,4,12 and 20 patients in group 2 respectively;the erythema score improved in 1,5,13 and 18 patients in group 1 respectively,and in 0,5,11 and 17 patients in group 2 respectively.No significant difference was observed between the two groups in response rates at any of the above four time points (P ＞ 0.05).Both the total score and erythema score significantly decreased after the 8-week treatment in both groups compared with the pretreatment scores (both P ＜ 0.05).No serious adverse reaction was observed in either of the two groups.Conclusions Hydroxychloroquine combined with loratadine and butyli flufenamatum ointment shows high efficacy and safety for the treatment of PLE.Topical butyli flufenamatum ointment is highly effective for the treatment of PLE,especially for PLE cases mainly presenting with erythema.

Aim To establish a cell model targeting on GLP-1 R,and evaluate its function by the cAMP assay,for screening the new class of GLP-1 analogues as anti-diabetic candidates. Methods An eukaryotic expression vector pEGFP-GLP-1 R was constructed and transfected into HEK293A cells.After selecting with G41 8,a cell line stably expressing GLP-1 R-GFP was estab-lished.The expression and the cellular distribution of GLP-1 R-GFP fusion protein were investigated by Western blot and fluo-rescence microscopy.Then,the activity of GLP-1 analogue Lira-glutide was evaluated by monitoring the content of cAMP via HTRF using this cell model.Results GLP-1 R-GFP-293A cell line was successfully established.GLP-1 R-GFP fusion proteins were mainly distributed in the cell membrane.The dose-respon-sive relationship experiments revealed that cAMP could be effec-tively stimulated by Liraglutide using this cell model.Conclu-sion This cell model could be used to detect the bioactivity of GLP-1 analogues in vitro,which lays a foundation for the screen-ing of GLP-1 analogues and small GLP-1 R agonists.
