人抵抗素基因cDNA的克隆

目的克隆人抵抗素基因(hRETN)cDNA,为进一步研究RETN的结构和功能提供实验基础.方法应用RT-PCR方法从中国人网膜脂肪垫总RNA中扩增出RETN 基因cDNA,克隆入载体pMD18-T中,形成重组载体pMD18-T/hRETN.通过蓝白斑筛选出阳性克隆,限制性内切酶酶切鉴定后对其进行测序.结果从脂肪组织总RNA中扩增得到363 bp片段hRETN基因,其cDNA序列与Genbank hRETN基因序列基本相同.结论成功地克隆中国人hRETN cDNA.     

环戊硫酮治疗干眼的临床疗效评价

Objective To investigate anethol trithione therapic efficiency on dry eye. Methods It was a prospective random double-blind controlled study. Eighty cases diagnosed dry eye in Ocular Surface Out-patient Clinic of Xiamen University Affiliated Xiamen Eye Center from 2006 to 2008 were divided into two groups: anethol trithione group and control group, 40 cases in each group. Every group was then divided into two subgroups: weak dry eye subgroup, middle and severe dry eye subgroup. All groups had been added with 0.05% refresh drops. All patients had been detected and evaluated by subjective symptoms of dry eye, visual acuity,corneal fluorescent staining(F1), break-up time(BUT) and Schirmer Ⅰ test (SⅠT) at pre-therapy and 3,7,28 d of post-therapy. All groups had been compared and analyzed by F test and sample mean difference (SMD) or median difference (MD) comparison between pre-therapy and post-therapy. Results Except of tear and red eye, the other subjective symptoms of dry eye, F1, BUT and SⅠT of weak dry eye subgroup of both groups had been improved at 7 d after therapy. Only those of middle and severe dry eye subgroup of anethol trithione group had been improved at 7 d after therapy compared with those of pre-therapy: SMD=0.96 (visual tiredness), 1.26 (dry and unsmooth sensation), 0.82 (foreign body sensation), 1.28 (burning sensation), 1.05 (photophobia), 1.48 ( pain ) ; MD=0.30 (visual acuity), 4.00 (F1) ,5.00 (BUT), 5.00 (SⅠT) [F=15.30 (visual tiredness), 15.68 (dry and unsmooth sensation ), 13.56 (foreign body sensation), 20. 91 ( burning sensation ), 18.90 (photophobia), 27.22 ( pain ), 10.54 (visual acuity), 188.21 (F1) ,261.76 (BUT) ,269.05 (SⅠT) ;P<0. 05]. Those of middle and severe dry eye subgroup of control group hadn't significantly been improved at 28 d after therapy: SMD=0.10 (visual tiredness) ,0.16 (dry and unsmooth sensation) ,0.09 (foreign body sensation) ,0.38 ( burning sensation ), 0.24(photophobia) ,0.36 (pain) ,0.23 (red eye) ; MD=0.10 (visual acuity) ,0.50(F1) ,0.50(BUT), 0.50(SⅠT) [F=1.76 (visual tiredness), 1.61 (dry and unsmooth sensation), 1.02 (foreign body sensation),2.39 (burning sensation), 2.42 (photophobia), 2.73 ( pain ), 2.55 ( red eye ), 1.46 ( visual acuity) ,2.35 (F1) ,2.90 (BUT) ,2.76 (SⅠT) ; P>0.05]. SⅠT of anethol trithione group had been improved more significantly after therapy (F=13.77, P<0.05). Conclusion Anethol trithione could significantly improve middle and severe dry eye patients' symptoms and signs whose lacrimal gland function survival and it has clinical application value.     

L-肌肽对大鼠硒性白内障的影响

Objective To explore the effect of L-canosine in preventing and treating rat cataract induced by sodium selenite. Methods This was an experimental study. Cataract was induced in the rats by sodium selenite. Rats were divided into 3 groups and each group has 3 ones. L-canosine eye drops (50 g/L or 20 g/L) and 0.9% normal saline were respectively instilled to the rat eye for 3 weeks and examined. L-canosine was added to the medium of cultured rat cataract lens at 1.00, 0.10 and 0.01 g/L for 1 week and then examined. Cataract lens were studied by using two-dimensional eletrophoresis. Results One week after instillation of L-canosine, the scores of rat cataract were 2.22±0.65, 2.39±0.98 and 2.83±0.38 in 50 g/L, 20 g/L L-canosine and control groups, respectively. The lesion in 50 g/l, L-canosine group was lighter than that of the control group. There was significant difference between these two groups (P=0.013). On the 2nd and 3rd weeks, there was no difference among these three groups. After 1 week for culturing cataract lens, there was no difference between these three groups. The results of two-dimensional eletrophoresis showed that the protein number was 182 and 161 in the L-carnosine and control groups, respectively. High molecular weight protein decreased and low molecular weight protein increased in L-carnosine group. Conclusions L-carnosine at 50 g/L could restrain the development of early stage rat cataract. L-camosine could modulate the rat lens protein in vitro, but could not affect lens cataract scores.
