Objective To evaluate β1、β2 and β3-adrenoreceptor mRNA expression in the sepsis rat model and to investigate the influence of the levels of β1、β2(especially β3AR)on heart dysfunction of sepsis rats.Methods The rats were randomly divided into two groups:control group and sepsis group,either group was then divided into four subgroups:6 h,18 h,24 h,36 h,RT-PCR was used to determined β1、β2 and β3-adrenoreceptor mRNA expression.Results The ratio of β1-AR/β-actin mRNA was lower in sepsis groups as compared with control.Among the two groups,the control group had the highest ratio(1.07±0.13)and sepsis 36h group had the lowest(0.59±0.13)with significant difference(P＜0.05).The ratio of β2-AR/β-actin mRNA was lower in sepsis group as mmpared with coatrol,but there was no statistical significance.The ratio of β3-AR/β-actin mRNA was higher in sepsis group as compared with control.Sepsis 36 h group was the highest with an increase of 73%as compared with control(P＜0.05).Conclusion These data suggest that the reduction of β1-AR mRNA and the increase of β3-AR mRNA might contribute to sepsis-related cardiac dysfunction.

Background Multifocal intraocular lens (IOL) can produce two focus distance based on the principle of diffraction-refraction,and the full range of vision is better than monofocal IOL.So multifocal IOL can provide cataract patients better far,middle and near distant vision.Objective This study was to investigate and compare the clinical efficacy between multifocal IOL and monofocal IOL implantation in the patients after cataract surgery.Methods One hundred eyes of 100 patients with cataract enrolled in Gaomi People's Hospital from June 2010 to September 2012 and were divided into the monofocal IOL group and multifocal IOL group,with the matched demographic and medical baseline characteristics between the two groups.All the patients were aware of the trial and a written informed consent was obtained from each patient prior to the surgery.Multifocal IOL (Acrysof ReSTOR SA60D3) was implanted in the multifocal IOL group,and monofocal IOL was implanted in the monofocal IOL group after phacoemulsification.Uncorrected distant visual acuity (UCDVA),best corrected distant visual acuity (BCDVA),uncorrected near visual acuity (UCNVA),best corrected near visual acuity (BCNVA),uncorrected middle distance visual acuity (UCMVA) and distant-corrected near visual acuity (DCNVA) between the two groups were observed and compared,and near stereo acuity,IOL higher-order aberrations under the pupillary diameters of 3 mm and 5 mm,optimum reading distance and reading speed were compared 3 months after surgery.The satisfaction rates of patients for each visual function district were analyzed by a questionnaire survey.Results UCNVA and DCNVA in the multifocal IOL group were significantly better than those of the monofocal IOL group 3 months after surgery,and the differences were statistically significant (t=15.48,22.44,both at P＜0.05).UCMVA at the distance of 25,30,40,50,60 cm in the multifocal IOL group were better than ones of the single IOL group (t=12.60,16.75,23.18,14.04,7.60,all at P＜0.05).Uncorrected near stereo acuity in the multifocal IOL group was (49.1 ±15.2),showing a significant reduction in comparison with (85.3 ± 18.6) of the multifocal IOL group (t=10.66,P＜0.05).The total higher-order aberrations,spherical aberration and coma under the pupil diameter of 3 mm and 5 mm were not significantly different between the two groups (all at P＞0.05).The optimal reading distance in the multifocal IOL group was (33.5 ± 4.1) cm,and was significantly shorter than (46.3 ± 5.2) cm of the monofocal IOL (t=13.67,P＜0.05).The reading speed in the multifocal IOL group was (172.5 ± 52.3) words/minute,and that in the monofocal IOL group was (108.3 ± 31.4) words/minute,with the significant difference between them (t =7.44,P＜0.05).The patients who were satisfied with the functional areas of near vision and middle-distance vision were more in the multifocal IOL group than those of the monofocal IOL group (x2=56.59,40.85,both at P＜0.05),but those in the distance vision zone between the two groups was no significant different (x2=3.09,P＞0.05).Conclusions Comparison with the monofocal IOL,multifocal IOL implantation for the treatment of cataract can obtain clear imaging both at the far-distance and middle-and near-distance.Multifocal IOL implantation can improve the life quality of cataract patients after operation.

BackgroundThe progressive death of retinal ganglion cells (RGCs) is the primary pathological characteristics of visual defects in glaucomatous eye.Research showed that endoplasmic reticulum stress (ERS) is involved in this progression.Glucose-regulated protein 78 ( GRP78 ) is a special marker of ERS.To understand the change in expression of GRP78 in the retina under the pressure induced is very important for the protection of visual function.Objective The present study was to observe the expression of GRP78 in rat retina with acute high intraocular pressure (IOP) and investigate the possible effect of ERS in acute glaucoma damage. MethodsFiftysix Wistar rats were randomly assigned to normal control group,anterior chamber punctured group and 12 hours,1 day,3,7,14 days groups following acute IOP rising.The acute high IOP models were established in the right eyes of 4.0 Wistar rats by paracentesis of the anterior chamber and infusion of normal saline solution into the anterior chamber.The histopathology changes of the retina were examined by hemotoxylin and eosin staining.The expression of GRP78 protein and mRNA in the retina were detected by immunohistochemistry and real-time fluorescence quantitative PCR.ResultsThe retinal layers and cells were clear with normal alignement in the rats of the normal control group and the anterior chamber punctured group.The edema and thickening of retinas appeared in 12 hours after molding and peaked in 1 day after molding.Then the retina decreased in thickness and atrophied from 3 days through 14 days.The expression levels of GRP78 protein (A value) were 0.195±0.006 in the nounal rats and gradually increased from 12 hours through 3 days (0.268±0.017) following molding with the peak value at 1 day (0.499±0.039 ),showing significant differences in comparison with the normal control group (t =0.098,0.304,0.073,P＜0.05),and the reduction in expression at 7 and 14 days were not significantly different from the normal control group ( t =0.002,0.001,P＞0.05 ).The relative value of GRP78 mRNA ( 2△△C1 ) in the retina was 1.011 ±0.013 in the normal control group and gradually up-regulated from 12 hours through 3 days with the peak value at Iday (2.141±0.171 ) and then down-regulated from the third day onwards.A significant difference was seen in 2-△△C1value between the normal control group and 12 hours group,1 day group or 3 group ( t =0.525,1.130,0.409,P＜0.05 ).However,the 2-△△C1 values of GRP78 mRNA at 7 and 14 days was similar to that of the normal control group (t=0.020,0.004,P＞0.05).ConclusionsGRP78 participates in the process of RGCs damage following acute high IOP.The results suggest that interfering with ERS may be helpful for protecting the retina and optical nerve from pressure-induced damage.

OBJECTIVE: To evaluate the relative factors influencing olfactory dysfunction in patients with chronic rhinosinusitis (CRS). METHOD: Visual analogue scale (VAS) was applied to measure the severity of olfactory dysfunction of 270 patients with CRS. Patients were divided into two groups, one was that the quality of life (QOL) of patients was affected by olfactory dysfunction (VAS > 5), the other was that without QOL affected by olfactory dysfunction (VAS ≤ 5). The association between age, gender, nasal polyps, allergic rhinitis, smoking history, early nasal surgery history and other clinical factors, and serum total IgE level, peripheral blood eosinophil count, peripheral blood mononuclear cell count and olfactory dysfunction was analyzed. RESULT: The number of patients with nasal polyps, allergic rhinitis, previous nasal surgeries, the level of serum total IgE, and the severity of edema were significantly increased in patients with impaired QOL associated with olfactory dysfunction (P < 0.05). Sex distribution, age, smoking history, deviation of nasal septum, eosinophil and mononuclear cell count did no statistically differ between the groups with and without impaired QOL associated with olfactory dysfunctions (P > 0.05). Serum total IgE increased (OR = 1.003, P < 0.01) and severe edema (OR = 2.483, P < 0.01) were the risk factors for the impairment of olfactory function, more notably for edema; whereas previous nasal surgeries was a protective factor (OR = 0.408, P < 0.01). CONCLUSION Sever edema and increased serum total IgE are risk factors, whereas previous nasal surgeries history is a protective factor for the olfactory dysfunction.
