AIM: To compare the accuracy of intraocular lens(IOL)power calculations by using five formulas(Haigis, SRK-T, Hoffer Q, Holladay-1, SRK-Ⅱ)in eyes with long axial lengths in order to improve the accuracy of predicating IOL powers.METHODS: Fifty-one eyes of 51 cases of age-related cataract and with mild long axial(24.5mm27mm) were collected who`s optical biometry were performed by the Zeiss IOL Master500 before operation.They underwent regular phacoemulsification and posterior chamber IOL implantation.The actual postoperative refraction was measured with the methods of phoropter and subjective optometry 3mo after surgery.Then we compared the differences of the predicted and actual postoperative refraction of the five formulas in each group.RESULTS: In the mild axial lengths cases, the differences between SRK Ⅱ formula and the other four formulas were statistically significant (P<0.05), and the difference between Hoffer Q and SRK-T formula was statistically significant (P<0.05);there was no difference among the other formulas (P>0.05).In the moderate and severe long axial lengths cases, the differences between SRK Ⅱ formula and the other four formulas were statistically significant (P<0.05), and the difference between Hoffer Q and SRK-T formula, Hoffer Q and Haigis formula were statistically significant (P<0.05);there was no difference among the other formulas (P>0.05).The differences of all the five formulas between the two groups were statistically significant (P<0.05).CONCLUSION: In the mild axial lengths cases, Haigis, SRK-T, Hoffer Q, Holladay-1 performed well.In the moderate and severe long axial lengths cases, Haigis, SRK-T and Holladay-1 performed better than other formulas.The accuracy of all the five formulas decreases as the axial length getting longer.

Objective To investigate the feasibility of iterative model reconstruction (IMR) combined with low tube voltage and low iodine intaken of contrast media in head and neck CT angiography (CTA). Methods Eighty patients with clinical suspicion of head and neck vascular disease underwent head and neck CTA were enrolled in this prospective study. According to random number table, patients were randomly divided into two groups. Group A (n=40) was scanned according to the protocol of 120 kV, 50 ml iopromide (370 mg/ml) and filtered back projection (FBP) reconstruction, and group B (n=40) was scanned with 80 kV, 30 ml iohexol (300 mg/ml) and IMR, while the other parameters kept consistent. Mann-Whitney U test was used to compare the enhanced CT value of arteries, image noise, signal noise ratio (SNR), contrast noise ratio (CNR), the score of image quality, effective radiation dose (ED) and iodine intaken of contrast media between two groups. Results The CT value at the origin level of common carotid artery were (316.9 ± 53.0) and (433.4 ± 101.8)HU in group A and B, image noise were (28.1 ± 6.8)and (12.1 ± 2.6)HU ,SNR were (11.9 ± 3.2) and (37.7 ± 13.3) ,and CNR were (10.2 ± 2.9) and (32.6 ± 13.3), respectively. There were showed significant differences in CT value, image noise, SNR and CNR between two groups (Z=-5.490,-7.592,-7.698,-7.660, P<0.05). The CT value at the origin level of internal carotid artery were (359.5 ± 54.3) and (443.5 ± 120.1) HU in group A and B, image noise were (18.8±6.2) and (6.8±1.7) HU ,SNR were 21.5±8.7 and 69.7±27.4 ,and CNR were 18.0±7.3 and 62.7± 26.4, respectively. The significant differences were acquired in CT value, image noise, SNR and CNR between two groups (Z=-3.022,-7.376,-7.496,-7.515, P<0.05). The CT value at M1 segment level of middle cerebral artery were (321.1±47.3) and (401.6±104.0) HU in group A and B, image noise were (32.3± 17.2) and (11.2 ± 2.7) HU,SNR were 12.4 ± 5.6 and 39.3 ± 18.4,and CNR were 10.7 ± 4.7 and 36.4 ± 17.7, respectively. There also showed significant differences in CT value, image noise, SNR and CNR between two groups (Z=-3.527,-7.487,-7.482,-7.535, P<0.05). The score of image quality of group A and B were 3.9 ± 0.7 and 4.5±0.6, which also showed significant difference between two two groups (Z=-3.517, P<0.05). The ED were (2.78 ± 0.13) and (0.84 ± 0.04) mSv for group A and B, which also showed significant difference between the two groups (Z=-7.706, P<0.05). The iodine intaken of contrast media were 1.85 g and 0.90 g in group A and B. Conclusion IMR combined with low tube voltage and low iodine intaken of contrast media can not only decrease effective radiation dose and iodine intaken of contrast media significantly, but also improve the imaging quality in head and neck CTA examination.

Objective At present, the risk factors for cognitive impairment in epilepsy patients are not quite clear.This study was to explore the impacts of the clinical features, emotional health and quality of life (QOL) on the cognitive function of the adult patients with mild cognitive impairment (MCI).Methods Using the Montreal Cognitive Assessment (MoCA) and Mini Mental State Examination (MMSE) scales, we evaluated the cognitive functions of the 109 adult epileptics of the outpatient clinic of neurology in Jinling Hospital.We assessed their emotional health with Hamilton Depression Scale-24 (HAMD-24), estimated their QOL with Quality Of Life in Epilepsy-31 (QOLIE-31), and collected their baseline clinical data by questionnaire survey.Results There were 67 cases of MCI (61.5%) among the 109 patients.The residential area was the strongest predictor of MCI in the adult epileptics (OR=0.226, 95% CI: 0.082-0.627).Among other risk factors of post-epileptic MCI were the total scores of HAMD-24 (OR=0.770, 95% CI: 0.644-0.921) and QOLIE-31 (OR=0.712, 95% CI: 0.575-0.880), QOL (OR=1.070, 95% CI: 1.015-1.128), cognitive function (OR=1.120, 95% CI: 1.043-1.203), and social function (OR=1.103, 95% CI: 1.035-1.175).Conclusion The incidence of MCI is high in adult patients with epilepsy.The development and progression of post-epileptic MCI can be delayed by more emphasis on the evaluation of cognitive function, emotional health, and quality of life.

Objective To investigate the morphological and functional alterations of peritoneum in uremic rats undergoing peritoneal dialysis(PD). Methods Thirty-five male Wistar rats were randomly divided into control group(sham operated group,n=6),uremia group(5/6 nephrectomy,n=6) and uremia with PD group(n=18).Uremia with PD group was subdivided into three subgroups according to different dialysis period(10 d,4 weeks and 8 weeks,n=6).Omenta were obtained for morphological examination,and peritoneal equilibration tests(PET) were performed to assess the transport function of peritoneal membrane. Results The number of blood vessels per high-power field in the uremia group,uremia with PD group and uremia with PD subgroups(5?3,10?5,17?5 and 19?4) were significantly increased compared with the control group(1?1),and that was much bigger in the uremia with PD group than the uremia group(P

BackgroundIdiopathic epiretinal membranes(ERMs) is a common eye disease condition that leads to progressive decline of visual acuity. Studying the risk factors relating to this disease will shed light on its pathogenesis and allow opthalmologists to screen the affected individuals among the high-risk population and prepare for prevention and management strategies. ObjectiveThis survey was to investigate the risk factors of idiopathic ERMs in the population undergoing routine health check-ups. MethodsThe clinical data of idiopathic ERMs was obtained from the population of routine health check-ups in Peking Union Medical College Hospital from November 2009 to October 2010. The examination outcomes were compared between the individuals with and without idiopathic ERMs. The demographic and clinical factors associated with idiopathic ERMs were analyzed and assessed using univariate and multivariate logistic regression analyses. Result A total of 27 400 people were included in the survey and idiopathic ERMs were diagnosed in 76 cases. No obvious eye complaint was obtained from the idiopathic ERMs. The number of people affected with idiopathic ERMs was 12 ( 12/11 659 ) in the below 40 years group, 21 (21/4595) in the 51-60 years group and 32 (32/2544) in the over 60 years group. Hypertension, diabetes, diedyslipidemia, renal function insufficiency ,and cataract were found in 42％ ,5％ ,66％ ,6％ and 8％ of the patients, respectively. The univariate logistic regression analyses revealed that significant correlations were found between age,hypertension,hyperlipidemia and history of cataract( P＜0. 01 ). Multivariate regression models showed that the risk of idiopathic ERMs increased in age of 51-60( OR=2. 5,95％ CI:1. 2-5.4,P=0.02) and over 60 years( OR =7.3,95％ CI:3.4-15.6 ,P＜0.01 ) and patients suffering from hyperlipidemia ( OR--2. 1,95％ CI:1. 3-3.5, P＜0. 01 ). ConclusionsOver the age of 50 years and hyperlipidemia are primary risk factors of idiopathic ERM.

To explore the plasticity of human amniotic mesenchymal cells(hAMCs) into cardiomyocyte-like cells,hAMCs were isolated from human amnion with collagenase digestion.Phenotype of the isolated cells was analyzed by flow cytometry(FCM).hAMCs were treated with 5-azacytidine and basic fibroblast growth factor(bFGF) to investigate their ability of differentiation into cardiomyocytes.The induced differentiated cells were evaluated by immunofluorescence for desmin and ?-actin expression and by RT-PCR for Nkx2.5,GATA-4 and alpha-myosin heavy chain(?-MHC) mRNA expression.The results showed that,after primary culture,hAMCs could reach a confluence of 80% with swirl like growth at 6 days.The cells proliferated rapidly after passages with a 100% confluence at 3~4 d.hAMCs were positive expression of CD44 and vimentin,but negative for CK19.After induced differentiation at 8~10d,the differentiated cells have close-up arranged with long spindle-shape.At 2 weeks and 4 weeks,induced cells expressed ?-actinin and cardiac-specific transcription factor Nkx2.5.Expressions of GATA-4 and desmin can be detected but ?-MHC can not in the hAMCs both before and after the induction.In conclusion,hAMCs have the ability of differentiation into cardiomyocyte-like cells,which means that hAMCs can be regarded as candidate cells for cellular cardiomyoplasty(CCM).

OBJECTIVETo observe the effect of rhubarb in treating secondary damage of central nerve system (CNS) in rats with acute hemorrhagic stroke (AHS) and to explore the possible mechanism.

METHODSThe rat's AHS model was established by autologous blood injection, the effect of rhubarb on the secondary damage of CNS, plasminogen (PLG) in brain and tissue type plasminogen activator (t-PA) were observed.

RESULTS(1) The nerve function deficit signs reappeared in about 70% model rats 4 - 6 days after modeling and reached the peak at day 6 - 8, scored as 1.63 +/- 0.72 on day 4 and as 2.32 +/- 1.12 on day 7; (2) Rhubarb could effectively improve the secondary nerve function damage, with the nerve deficit scores kept to 1.24 +/- 0.19 from day 4 on, and no sign of secondary CNS damage was shown. The nerve deficit score was 1.22 +/- 0.15 on day 7 in the rhubarb treated group, showing significant difference as compared with that in the model group (P<0.05); (3) The specific amplified products of t-PA mRNA on day 3 and that of PLG mRNA on day 7 in CNS of model group were significantly higher than those in the sham operated group and the rhubarb treated group.

CONCLUSIONRhubarb could effectively reduce the secondary CNS damage in rats with AHS, it might be related with the suppressive effect of rhubarb on tPA mRNA and PLG mRNA expression in CNS.
