·AlM: To investigate the distribution and related factors of corneal spherical aberration in the age-related cataract patients, and to provide a scientific basis for the application of aspheric intraocular lens ( lOL ) in cataract surgery patients.
· METHODS: Retrospective study of 509 age -related cataract patients of 610 eyes in our hospital. Corneal spherical aberration, corneal curvature, corneal astigmatism and corneal Q -value were examined by iTrace visual function analysis. Statistical software SPSS16.0 was used to analyze statistically.
· RESULTS: The range of corneal spherical aberration was 0 ~1.800μm. The mean coefficient of corneal spherical aberration was 0.266 ±0.010μm. Corneal spherical aberration was no significantly correlation with age, corneal curvature, corneal astigmatism ( r =0.71, 0.56, 0.93, P>0.05 ). There was positive correlation between corneal spherical aberration and Q-value ( r=0.086, P=0.03).
· CONCLUSlON: Corneal spherical aberration varied greatly among age-related cataract patients.The choice of asphericity intraocular lens should be a matter of personal choice.

Objective To improve the awareness of fetal cardiac rhabdomyomas (CRs) and investigate a better model for prenatal diagnosis and treatment through analyzing imaging findings and prognosis.Methods A retrospective study was conducted on 23 cases of CRs which were diagnosed by ultrasound in Obstetrics and Gynecology Hospital of Fudan University from January 2008 to November 2015.General conditions,imaging features,prognosis and follow-up data of the 23 cases were described.Results The average gestational age of the 23 fetuses at diagnosis was (29.8±4.1) (22.4-35.7) weeks.Seventeen out of the 23 gravidas received prenatal multidisciplinary consultation.Among all 23 gravidas,three (13％) were lost to follow-up,12 (52％) decided to terminate the pregnancy,and the other eight (35％) continued to term pregnancy and their babies were followed up for three years.Of these eight cases,two cases received prenatal brain MRI and no tuberous sclerosis complex (TSC) was detected,no CRs was identified during the follow-up,and their physical and mental developments were both normal.One case was diagnosed with suspected subependymal nodules by prenatal brain MRI in our hospital,but the MRI images was normal when scanned in the other hospital,and follow-up data revealed neither CRs nor abnormal physical and mental developments.Four cases did not received prenatal brain MRI,but the MRI images of neonatal brains indicated TSC,besides,follow-up data showed that seizures were observed,physical developments were all normal,but three of the four cases had mental retardation;CRs disappeared in only two of the four cases.One case had neither prenatal nor neonatal MRI,but follow-up data showed that CRs had disappeared and physical and mental developments were both normal.Conclusions Prenatal diagnosis of fetal tuberous sclerosis is crucial to the prognosis of CRs.Prenatal ultrasonography in combination with cranial MRI improves the accuracy of prenatal diagnosis of CRs complicated with TSC and assists in clinical decision-making and prognosis analysis.

[ ABSTRACT] AIM:To investigate the effect of silencing cell division cycle 25a ( CDC25a) gene on the prolifera-tion of human hepatoma HepG2 cells.METHODS:CDC25a gene in human hepatoma HepG2 cells was silenced by RNA interference.Real-time PCR was applied to detect the expression of CDC25a, cyclin E and CDK2 at mRNA levels in the HepG2 cells.Western blotting was applied to detect the expression of CDC25a at protein level.In addition, MTT assay, Giemsa staining and flow cytometry were used to measure the proliferation of human hepatoma HepG2 cells.RESULTS:The expression of CDC25a at mRNA and protein levels in RNA silence group was lower than those in negative control group and normal control group (P<0.05).The mRNA expression of cyclin E and CDK2 in silence group was lower than that in negative control group and normal control group (P<0.05).The cell proliferation in silence group was lower than that in negative control group and normal control group ( P<0.05) .The results of flow cytometry revealed that the cells in silence group were blocked in G1 phase.CONCLUSION:Infection of LV-CDC25a-RNAi recombinant to the HepG2 cells effec-tively inhibits the CDC25a gene expression and the proliferation of human hepatoma cells, and arrests the cells in G1 phase, suggesting that CDC25a gene may be a key target for the treatment of liver cancer.

Objective:To test the expression of Minichromosome maintenance complex component 7(MCM7) protein in hepato-cellular carcinoma(HCC) of different species including human, rat and tree shrew (tupaia) by cross-species oncogenomics approach, and to investigate the relationship between the expression of MCM7 and the development of hepatocellular carcinoma and its clinical significance. Methods:Western blot and Immunohistochemistry were applied to detect the expression levels of MCM7 protein in HCC tissues,corresponding HCC-adjacent liver tissues and normal liver tissues collected from different species including human, rat and tree shrew, respectively. The clinicopathologic factors were also analyzed with the results of Immunohistochemistry. Results:Western blot analysis showed that the expression of MCM7 protein in HCC tissues of human and rat were higher than that in corresponding HCC-ad-jacent liver tissues and normal liver tissues, respectively and significantly (P<0.05). However, the expression of MCM7 protein in HCC tissues of tree shrew were also higher than that in corresponding HCC-adjacent liver tissues and normal liver tissues, but no significant difference was found among three types of tissues (P>0.05).There was also no significant difference between HCC-adjacent liver tis-sues and normal liver tissues in three species (P>0.05). Immunohistochemical analysis showed that MCM7 protein was mainly ex-pressed in nucleus of HCC cells, and the positive rate of MCM7 protein in HCC tissues of human, rat and tree shrew were significantly higher than that in corresponding HCC-adjacent liver tissues and normal liver tissues, respectively (P<0.05). However, no significant difference was found between HCC-adjacent liver tissues and normal liver tissues (P>0.05). Moreover, the protein level of MCM7 was intimately related to patient's HCC stage, extrahepatic metastases and postoperative recurrence (P<0.05). Conclusion:MCM7 protein might play a pivotal role in hepatocarcinogenesis. In addition, it was probably related to patient's HCC stage, extrahepatic metastases and postoperative recurrence. It seems very likely that MCM7 may be applied as a new molecular target in HCC prevention and treat-ment.

Objective: To research the activity of antibacterial proteins isolated from Musca domestica during larvae-pupae metamorphosis. Methods: The 5-day-old larvae of Musca domestica were injured with a needle. 24h later, the larvae which had changed into pupae were selected. The antibacterial protein was isolated by a four-step protocol including grinding, heating, CM-sepharose F. F. cationexchange chromatography and another CM-sepharose F. F. chromatography. Antibacterial activities of samples were tested by an ultrasensitive radial diffusion assay using Staphylococcus aureus as the indicator organism. The molecular weight of the isolated protein was determined by SDS-PAGE.Results: The molecular weight of this isolated protein was 43kDa, and its antibacterial activity was strong. Conclusions: A kind of protein with strong antibacterial activity can be produced in the Musca domestica during larvae-pupae metamorphosis.

Objective To quantify the expressions of collagen metabolic markers carboxy terminal propeptide of type I procollagen(PICP),nitrogen terminal propeptide of type I procollagen (PINP),nitrogen terminal propeptide of typeⅢprocollagen(PⅢNP),type I collagen carboxy terminal telopeptide (ICTP), matrix metalloproteinases(MMPs)and the tissue inhibitor of metalloproteinases(TIMPs)in the serum of atrial fibrillation patients by enzyme linked immunosorbent assay(ELISA),and to discuss the atrial structural remodeling during atrial fibrillation(AF).Methods 71 elderly patients were enrolled,24 patients had permanent AF,24 patients had paroxysmal AF,and 23 patients were in sinus rhythm.The serum levels of all markers were measured by ELISA. Results PICP was increased in permanent AF group versus the paroxysmal AF group and sinus rhythm group by 25.4%and 42.8%(all P<0.05),respectively.PⅢNP was increased in permanent AF group versus the paroxysmal AF group and sinus rhythm group by 17.9a% and 35.6%(all P<0.05),respectively,and was increased in the paroxysmal AF group versus the sinus rhythm group by 15.0%(P<0.05).PINP and ICTP did not differ significantly between the 3 groups(all P >0.05).MMP-1 was significantly increased by 25.6%(P<0.05)in the paroxysmal AF group versus the sinus rhythm group.MMP-2 was also significantly increased in permanent AF group versus the paroxysmal AF group and sinus rhythm group by 54.9%and 37.9%(all P<0.05),respectively.MMP-7,MMp-9 and TIMP-1 did not differ significantly between the 3 groups(P>0.05).TIMP-2was significantly decreased in the permanent AF group and paroxysmal AF group versus the sinus rhythm group by 21.8%and 11.8%(P<0.05),respectively. Conclusions Disturbance in the balance of MMP/TIMP system may perturb the balance of collagen synthesis and degradation during atrial fibrillation.This may be a contributing mechanism to atrial structural remodeling in atrial fibrillation,and may correlate with the initiation and maintenance of AF.
