Background Aspheric intraocular lens (IOL) is designed to reduce the spherical aberration of the eye after cataract surgery and to obtain better visual quality.However,the selection of a personalized aspheric IOL is a problem to be solved.Objective This study was to compare the wavefront aberration and quality of vision of patients between the implantation of negative spherical aberration IOL and non-aberration IOL,and to investigate the relationship between corneal Q values and postoperative spherical aberration.Methods One hundred and four eyes of 90 patients with age-related cataract were randomized into two groups.Fifty-two eyes of 46 patients who received a Tecnis Z9001 IOL implantation were assigned as the negative spherical aberration IOL group and 52 eyes of 44 patients who received Akreos AO IOL without aberration were assigned as the non-aberration IOL group.The preoperative corneal Q values were measured and the mean Q value(Q)was computed.Then the patients in the two groups were further divided into 2 subgroups,respectively,based on their Q values were over or below (Q）.The corneal Q values,root mean square(RMS) of ocular spherical aberration,coma and total higher-order aberrations(HOAs) for 5 mm diameter pupil,scotopic contrast sensitivity with or without glare at 6 mm pupil diameter were measured 3 months after surgery.Results The pre-and post-operative corneal Q values were insignificantly changed (t =1.447,P =0.151).The spherical aberration in the negative spherical aberration IOL group was(0.059-±0.047)μm,and that in the non-aberration IOL group was(0.110±0.066)μm,with a statistically significant difference between them (t =-4.567,P=0.000).Scotopic contrast sensitivities at intermediate and high frequencies were significantly better in the negative spherical aberration IOL group than in the non-aberration IOL group (t =2.495,t =2.359,P ＜ 0.05).There was no significant difference in coma and HOAs between the two groups after operation (P ＞ 0.05).Weak positive correlations were seen between the pre-and post-operative corneal Q values and spherical aberration in the two groups(r=0.277,0.292,0.285,0.325,all at P＜0.05).However,no significant differences were found in spherical aberration,contrast sensitivity and scotopic contrast sensitivity between the different subgroups (P ＞ 0.05).Conclusions Negative spherical aberration IOL has lower spherical aberration and better scotopic contrast sensitivity than non-aberration IOL.The results suggest that it may be not enough to choose the corneal Q value only as the single reference criterion for selection of aspheric IOL.

Objective To explore the clinical and pathological features of primary IgA nephrology in patients of different gender.Methods The clinical manifestations,laboratory examination and renal pathology results were compared in 192 IgA nephrology patients.Results Not only the onset age of the male patients was older than that of the female ones (P<0 .05 ),but also the course of disease before the kidney biopsy of male patients was longer than that of the female ones (P<0.05).Besides,the proportion of edema in the male patients was lower (P<0.05).The mean arterial pressure,hemoglobin and 24 h urine protein levels were higher in the male patients at the time of kidney biopsy.Besides,the proportions of high blood pressure,hyperuricemia and hypertriglyceridemia were all higher in the male patients.Furthermore,eGFR of the male patients was lower than that of the female ones (P<0 .05 ).There was a significant difference in the gender distribution of clinical and pathological types (χ2=12.666,P<0.05),and the male and female patients also significantly differed in the 24 h urine protein and CKD grouping (Z=-3.118,Z=-3.246,P<0.05).However,there was no significant sex difference in Lee pathology grading or immunofluorescence type (Z=-1.881,χ2 =-0.187,P>0.05 ).Patients of different gender significantly differed in the renal-interstitial lesions grading (Z=-3.0432,P<0.05);to be more specific,the scores of glomerulosclerosis and renal tubule interstitia were higher in the male patients (P<0.05).Conclusion Patients of different gender differ in the clinical and pathological features of primary IgA nephrology.And clinical pathology of male patients is worse than that of female ones.

Objective To determine the protective effect of osteoprotegerin (OPG), receptor activator of nuclear factor kappa-B (RANK) and RANK ligand (RANKL) on avascular necrosis femoral head.Methods Necrotic tissue or corresponding normal tissues were collected from 29 avascular necrosis femoral head patients.Quantitative Real TimePCR ( qPCR ) is used to evaluate mRNA expression of OPG , RANK and RANKL.OPG and RANKL protein levels were estimated by Western blot.Results The results of qPCR showed that the expression of OPG in the necrotic tissue was significantly higher than that in the normal tissue (4.56 ±0.37) (3.39 ±0.52) (P<0.05).The expression levels of RANKL mRNA in necrotic tissues and normal tissues were (0.86 ±0.11) and (0.31 ±0.08), respectively,the difference was statistically significant (P<0.05).The expression levels of RANK mRNA in necrotic tissues and normal tissmes were(0.87 ±0.12), (0.56 ±0.13) respectively,the difference was statistically significant (P<0.05).The ratio of RANKL/OPG and RANK/OPG in normal tissues were 0.69 and 0.52, respectively.In the necrotic tissues, RANKL/OPG and RANK/OPG ratios were 1.35 and 0.61, respectively.Results of Western blot showed that the expression of OPG in necrotic tissues was consistent with that in normal tissues.The expression of RANKL protein was detected in all samples , and the expression of RANKL protein in necrotic tissue and normal tissue was almost the same.RANK protein expression was not detected in all samples.Conclusion OPG, RANK and RANKL play important roles in progress of bone remodeling in necrotic area and in disturbance of bone homeostasis and might have an effect on bone destruction and subsequent collapse of hip joint.

Objective：To study anatomic basis of ligaments factors in carpal radial instability. Methods:The length, width, thickness and maximum length of radial scaphoid capitate ligament(RSCL) , radial lunate ligament(RLL) , radial scaphoid lunate ligament(RSLL),radial scaphoid ligament(RSL), scaphoid trapezium ligament(STmL), scaphoid lunate interosseous ligament(SLIL), scaphoid triangular ligament(STgL) and radial ulnar triangular ligament(RUTgL)were measured in the neutral position. The length of RSCL, RLL, RSLL, RSL and RUTgL in the maximum position of radial deviation, ulnardeviation, palmarflexes and dorsiflexes were also measured. The normal and maximal distance of scaphoid lunate gap(SLG) , scaphoid trapezium gap(STmG), radial scaphoid gap(RSG) and capitate lunate gap(CLG) were measured,especially for variation of SLG in the condition of different ligament lesions. Results:Volar carpal radial ligaments were thicker than dorsal ones. The injuries of SLIL, STmL, RSL and CLL were considered generally when SLG>4.78±0.54mm, STmG>3.71±0.32mm, RSG>5.77±0.79mm, CLG>4.62±79mm; when SLIL was incised completely, SLG>5mm. Keeping anatomic structure of SLIL and incising other ligaments, there existed no obvious variation in SLG. Keeping dorsal part and incising proximal and palmar ones, no obvious variation of SLG can be observed. Conclusions: There were no effects on SLG when carpal radial ligaments (except dorsal part of SLIL) were injuried .Dorsal part of SLIL played a very important role in keeping SLG normal.

Objective To evaluate the clinical effect of acupuncture combined with estazolam for the treatment of primary insomnia with heart and spleen deficiency type. Methods Seventy qualified patients were randomized into treatment group and control group, 35 in each group. Both groups received oral use of estazolam before bed time for 6 continuous weeks, and acupuncture group was additionally given acupuncture for regulating governor vessel and tranquilizing spirit on acupoints of Baihui(GV20), Yintang(GV29), Shenting(GV25), Anmian (EX-HN22), Shenmen(H7), Sanyinjiao(SP6), 3 times a week and lasting for 6 continuous weeks. The sleep state of the patients was estimated according to Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS) and Athens Insomnia Scale(AIS) before treatment, on the third and the sixth week of treatment, and one month after the completion of treatment. Results (1) Five cases in the treatment group and 3 cases in the control group were dropped out for not completing the treatment timely. In the end , 30 cases in the treatment group and 32 cases in the control group finished the trial. (2) The total effective rate in the treatment group was up to 90.0%, and was 71.9% in control group, the difference being significant(P<0.01).(3) Compared to the control group, the scores of PSQI, ESS and AIS were much decreased in treatment group on the third and the sixth week of treatment , and one month after treatment(P<0 . 05 or P<0 . 01). Conclusion Acupuncture for regulating governor vessel and tranquilizing mind combined with oral use of estazolam exerts certain therapeutic effect for the treatment of heart and spleen deficiency type insomnia, and the effect was superior to that of estazolam alone.
