OBJECTIVE:To prepare the minoxidil gel and to establish a quality control method for the gel.METHODS:Carbopol934was used as the gel base;the content of minoxidil was determined with UV-spectrogram and the stability test was performed.RESULTS:There was a good linearity of calibration curve of minoxidil in range of2～10?g/ml(r=0.9999).The average recovery was99.8%,and RSD was0.67%(n=4).The gel was stable.CONCLUSION:The gel is reasonable in for?mulation,simple and accurate in quality control,as well as satisfactory in stability.

Objective To investigate the learning and memory functions,expression changes of disintegrin and metalloprotease 10 (ADAM10) mRNA in hippocampus in the aged rats with chronic cerebral hypoperfusion as well as the effect of atorvastatin on them.Methods A total of 72 rats were randomly divided into sham operation,cerebral hypoperfusion and atorvastatin treatment groups.A permanent bilateral common carotid artery occlusion (2VO)model was induced.Atorvastatin 10 mg/(kg · d) was administered orally after procedure in the atorvastatin treatment group.Real-time fluorescence quantitative polymerase chain reaction was used to detect the expression of ADAM10 mRNA in bilateral hippoocampus at 1,2,4,and 16 weeks after modeling,Results Two weeks after modeling,the learning and memory functions were decreased significantly in the cerebral hypoperfusion group compared to the sham operation group (P ＜ 0.05).At 4 and 16 weeks after modeling,they were further decreased (P ＜0.01); there were no significant differences in the learning and memory functions at 1,2,and 3 weeks after modeling between the atorvastatin treatment group and the cerebral hypoperfusion group,however,they were improved significantly at 16 weeks compared to the cerebral hypoperfusion group (P＜0.01).The expression of ADAM10 mRNA in hippocampus at different time points after modeling in the cerebral hypoperfusion group was down-regulated by 22％,43％,35％,and 50％,respectively compared to the sham operation group (all P ＜0.05).The expression of ADAM 10 mRNA in hippocampus at 2 weeks in the atorvastatin treatment group was higher than 22％ in the cerebral hypoperfusion group (P＜0.05).There were not significant differences at other time points.Conelusions Chronic cerebral hypoperfusion results in the down-regulation of the expression of ADAM10 mRNA in hippocampus in the aged rats,and atorvastatin may inhibit down-regulation of the expression of ADAM10 mRNA at early stage.

Objective To investigate the effects of USP4 on the proliferation of human hypertrophic scar fibroblasts(HSFB).Methods HSFB were cultured in vitro.The fourth generation of HSFB in logarithmic growth phase was selected in the experiment.HSFB were intervened by Vialinin A which was the inhibitor of USP4 for 0,12,24,48 h,then collected cells and the their expression of USP4 and TβRI and Smad7 protein was detected by Western blot.MTT assay was used to detect the effect of Vialinin A on the proliferation of HS fibroblasts and the cells were divided into experimental group and control group(without intervention).Results After treatment with Vialinin A in HSFB,the expression of USP4 and TβRI protein in HSFB decreased gradually,especially in 12 h(P<0.05),and Smad7 protein expression was increased gradually(P<0.05).The proliferative activity of intervened HSFB reduced gradually,the difference between experimental group and control group was statistically significant(P<0.05).Conclusion USP4 might inhibit the proliferation of scar cells and down-regulation of USP4 expression in hyperplastic scar fibroblasts,which can slow proliferative activity of intervened HSFB by regulating TGF-β/Smad signaling pathway.

AIM: To investigate whether potassium cyanate can inactivate glyceraldehydes 3-phosphate dehydrogenase (GAPDH) and thioltransferase (TTase) in bovine lens.METHODS: Fresh intact bovine lenses were incubated with 100mmol/L potassium cyanate (KCNO) for 7 and 12 days respectively. Then all lens were incubated in 50mmol/L DMEM solution. The proteins in the watersoluble fractions from the normal control and the cyanate-modified lens were extracted. The activity of GAPDH and TTase in the water-soluble fraction after incubation at 37℃ was measured by spectrophotometer.RESULTS: GAPDH activity was significantly lower in the cyanate-modified lens proteins than that of the normal control (P<0.01), and considerably diminished in protein incubated with 100mmol/L potassium cyanate for 12 days. There were statistically significant differences in the activity of TTase between the normal control lenses and the carbamylated lenses incubated for 7 days (P<0.05) and 12 days (P<0.01). However. there was no statistical difference between the samples incubated with 100mmol/L KCNO for 7 and 12 days (P=0.19296).CONCLUSION: This study provides evidence to show carbamylation is able to inactivate GAPDH and TTase in bovine lenses. This may have implications for the susceptibility of lenticular GAPDH and TTase to carbamylation, and also for the research on pathogenesis of cataract.

Objective To collect and summarize long-term complications of glucocorticoid (GC) in treatment of Diamond-Blackfan anemia (DBA).Methods A total of 17 DBA patients,treated with GC more than 1 year from December 2009 to November 2012 in Being Children's Hospital,Capital Medical University,were retrospectively investigated.The data of general information,drug treatment,treatment response,height and body mass in different therapy periods,and therapy related adverse reaction were collected.The data entry and the statistical analysis were performed using SPSS 16.0 software.Results Seventeen cases which fulfilled the research criteria were enrolled.The 58.8 percent of cases (10/17) began GC therapy from the age younger than 6 months.The 76.4 percent of the cases (14/17) started prednisone therapy with the dosage ≥2 mg/(kg · d),and the median time of maintenance therapy with this dosage was 2 months (1-5 months).The median time of prednisone dosage greater than 0.5 mg/(kg · d) was 6 months (3-48 months).Patients were divided into 2 groups at the beginning of therapy according to whether their age was younger or older than 6 months.The median height of younger age group was-1.0 SD (-3.5-1.0 SD) of corresponded age-sex-standard height at the beginning of prednisone therapy,and was dropped to-3.5 SD (-3.5--2.0SD)afterhalfyeartreatment.For older age group,it was0.0 SD(-1.5-2.0 SD)and-0.5 SD (-1.5-0.5 SD) respectively.During the therapy,there were 1 fracture,2 measles pneumonia,3 pneumonia,3 hirsuitisms,5 thrushes,and 12 central obesity cases.Conclusions GC related adverse reaction might appear when applying prednisone for the treatment of DBA in long term.It was suggested that GC therapy should start after 6 months old if possible,and the duration of 0.5 mg/(kg · d) GC treatment should be reduced as short as possible.

In 4 602 subjects for routine check-up,blood uric acid,total cholesterol,triglyceride,high density lipoprotein-cholesterol,and low density lipoprotein-cholesterol were determined.Results showed that the overall prevalence of hyperuricemia in Nanning,Guangxi was 19.8％ (28.8％ in male,9.4％ in female).Blood uric acid and lipids in hyperuricemia group were higher than those in normal uric acid group(all P＜0.01).Serum uric acid had a positive correlation with total cholesterol,triglyceride,low density lipoprotein-cholesterol,but it was negatively correlated with serum high density lipoprotein-cholesterol.The prevalence of hypercholesterolemia was 30.8％,and that of hypertriglyceridemia was 22.2％.Logistic multi-factor regression analysis showed that men,high total cholesterol,triglyceride,and low density lipoprotein-cholesterol could be independent risk factors for hyperuricemia,and that high density lipoprotein-cholesterol was a protective factor.The prevalence of hyperuricemia in population of Nanning,Guangxi during health examination is high.Hyperuricemia is closely associated with dyslipidemia.Timely intervention of hyperuricemia can reduce the related diseases effectively.
