1.Effects of the position of posterior chamber intraocular lens on visual quality
International Eye Science 2014;(12):2172-2175
lntraocular lens ( lOL) often has different degrees of tilt, decentration and rotation in the eye. The deflection of lOL is an important factor to impact on the visual quality of the patients with cataract surgeries. Vision was commonly used to evaluate visual quality before. ln recent years, some new methods are also introduced to evaluate visual quality, such as optical aberration, modulation transfer function ( MTF ) and subjective visual perception. They show that the lOL deflection will cause decreases in eyesight and MTF, cause increase in aberration, lead to ametropia and so on. Therefore, a better evaluation of the effects of lOL deflection on visual quality, has significance for lOL selection, positioning and cataract individualized treatment.

This study was designed to validate the correlation between integrated pharmacokinetic and therapeutic effects of alkaloids using bile processed Rhizoma Coptidis (BRC). Rats were divided into three groups: normal, disease model, model+BRC. Rats were induced to have an excessive heat syndrome. Rectal temperatures were collected at 0, 3, 6 and 9 h after single oral administration of the drugs. The plasma concentrations of three alkaloids were quantified at different times by UPLC-MS/MS after the administration of BRC. An approach of self-defined weighting coefficiency was created to the holistic pharmacokinetic profiles of alkaloids in BRC. The classified and integrated synthetic concentrations were obtained, and then the pharmacokinetic parameters of alkaloids were calculated from non-compartmental model analysis. The potential relationship between the integrated mean concentration of alkaloids and the antifebrile efficacy was investigated. The holistic t(max) of alkaloids was 1.11 h, the antifebrile effect of BRC at 3 h was improved over the model group. Double peaking appeared in the integrated blood concentration-time curve, the second t(max) of alkaloids was 4.82 h. The antifebrile effects of BRC at 3-6 h were significant, and the antifebrile effects at 6-9 h was decreased significantly. Dynamic variation of alkaloids of BRC in the body exhibited the similarity to the pattern of its antifebrile effect.

Objective To identify the glycometabolism features ofC57BL/Ksj db/+ mice at gestational period and provide the evidence for the mice used as the animal model of gestational diabetes mellitus (GDM).Methods Ten C57BL/Ksj db/+ female mice and ten wild female mice were randomly selected and mated with wild male mice respectively.Day 3 before mating,days 6,11 and 17 of pregnancy,and day 6 after delivery represented pre pregnancy,early-pregnancy,mid-pregnancy,late-pregnancy and post-pregnancy periods,respectively.The levels of glucose tolerance and fasting insulin of female mice were compared at progestation,different gestational periods and puerperium between the two groups.Days 6,11,14,17 and 20 (before labor) of pregnancy served as five time-points of pregnancy,leptin levels of female mice of the two groups were dynamically monitored during pregnancy,and analyzed at different gestational ages.The data were analyzed by Tukey test of one-way ANOVA.Results (1) Compared with the normal pregnant mice,the levels of glucose tolerance of C57BL/Ksj db/+ female mice were significantly decreased,while the levels of fasting insulin were dramatically increased with the progression of pregnancy [day 6 of pregnancy,(8.6 ± 0.6) mU/L vs (7.5 ±1.1) mU/L; day 11 of pregnancy,(9.8±0.6) mU/L vs (8.5± 1.1) mU/L; day 17 of pregnancy,(10.4±0.8) mU/L vs (9.9±0.5) mU/L; t=1.859,4.056 and 3.078,P=0.085,0.000 and 0.000] and recovered to the pre-pregnancy level after delivery.(2) The level of leptin in serum of C57BL/Ksj db/+ pregnant mice was significantly higher than that at non-pregnant period [pre-pregnancy and days 6,11,14,17 and 20 of pregnancy:(911.0±238.8) ng/L,(1 342.2± 132.3) ng/L,(1 821.9±238.2) ng/L,(1 816.3± 142.3) ng/L,(1 752.4± 126.6) ng/L,and (1 926.4±61.6) ng/L,respectively; t=3.887,8.210,8.161,7.585 and 9.153,P=0.005,0.000,0.000,0.000 and 0.000],but showed no apparent change with the gestational ages after mid-gestation.Conclusion Changes of glycometabolism and the levels of leptin and insulin of C57BL/Ksj db/+ pregnant mice during pregnancy are similar to those of GDM patients,the levels of fasting insulin are dramatically increased with the progression of pregnancy,and return to normal after delivery,the level of leptin is higher than that at non-pregnant period,but is not correlated with the gestational ages.C57BL/Ksj db/+ pregnant mice can be used as the animal model of GDM.

Objective To investigate the expression of Beclin1,p62 and Atg5 in serous ovarian cancer and its clinical significance.Methods The expression of Beclin1,p62 and Atg5 was detected in 50 serous ovarian cancer tissues by immunohistochemical method,and the relationship between their expression levels and the clinical parameters of serous ovarian cancer patients were analyzed.Results The expression of Beclin1 and Atg5 in serous ovarian cancer tissue was significantly lower than that in normal ovarian tissue,but p62 was significantly higher than that in normal ovarian tissue,and the difference had statistically significance (P<0.05).The expression of Beclin1 and Atg5 were correlated with degree of cell differentiation and clinical stage (P<0.05),while the expression of p62 was associated with clinical stages and lymph node metastasis (P<0.05).Conclusions The abnormal expression of Beclin1,p62,Atg5 in serous ovarian cancer,which can lead to reduced autophagy body formation and autophagy activity,may be involved in the occurrence and development of serous ovarian cancer.
