AlM:To observe the relationship between axial length and complications of phacoemulsification with intraocular lens ( lOL) implantation in high axial myopia eyes and normal axis eyes.
METHODS: A retrospective review of 843 consecutive patients ( 1 042 eyes ) of cataract extraction with phacoemulsification and lOL implantation in our hospital from February 2012 to February 2013 was performed. The patients were divided into two groups according to the axial length: 853 eyes were in normal axis group ( 21-24mm) and 189 eyes were in high axial myopia group (≥26mm). The two groups were compared regarding surgical complications, such as vitreous loss, posterior capsular rupture, nucleolus drop, and abnormal location of lOL.
RESULTS:Age was a risk factor in both groups. There was positive correlation between age and surgical complications, and between axial length and surgical complications, especially for complications with posterior capsular rupture and vitreous loss.
CONCLUSlON:As the results illustrate, in this survey, age and high axial lengthare statistically significant risk factors for incidence of complications of phacoemulsification. Anticipation of these complications and also preparation and prophylactic measures may decrease incidence of these complications.

Objective:To explore the mechanism of the cytotoxicity of human NK cells induced by atorvastatin to colon cancer cell lines. Methods:After colon cancer cells (HCT-116,SW-480,Caco-2) were cultured with different concentrations of atorvastatin, CCK-8 assay was used to assess the effect of atorvastatin on growth of colon cancer cells. The amplification of human NK cells was induced by SCGM medium in vitro. Automatic biochemical analyzer was applied to test the cytotoxicity of NK cells to colon cancer cells which cultured with different concentration of atorvastatin. FCM was used to detect the expression rate of MICA/B on the cells. Results:(1) The cultivation of NK cells:The proportion of NK cells attained to 93. 1% from 4. 5% after cultured for 10 days. (2) The effects of atorvastatin on the growth of the colon cancer cells:After cultured with atorvastatin,the inhibition rate of HCT-116 cells was higher than that in control when the density of atorvastatin increased from 5 μmol/L to 40 μmol/L after 48 h and from 1. 25 μmol/L to 40 μmol/L after 96 h ( P<0. 05 ) . Correlation analysis showed that the concentration of atorvastatin and the growth inhibition rate of HCT-116 cells were positively correlated(r[48 h]=0. 13,r[96 h]=0. 22,P<0. 05). (3) The cytotoxicity of NK cells to colon cancer cells effected after atorvastatin: In different atorvastatin concentrations groups,the cytotoxicity of NK cells to three colon cancer cell lines was all higher than that in control ( P<0. 05 ) . The atorvastatin concentration was from 2. 5 μmol/L to 10 μmol/L for HCT-116 cells,from 5 μmol/L to 20μmol/L for SW-480 cells,and from 2. 5μmol/L to 20μmol/L for Caco-2 cells. Among the three cell lines, the cytotoxicity of NK cells to HCT116 was the highest in the same concentration. (4)NK cells by atorvastatin cutting statins 96 h,the concentration of 20 mmol/L and 40 mmol/L inhibition rate was higher than that of control group,more than other groups on NK cell growth without significant effect. ( 5 ) The impact of atorvastatin on MICA/B expression of colon cancer cells: After cultured with different concentrations of atorvastatin,the expression of MICA/B on colon cancer cells was higher than that in control(P<0. 05). The concentration was 2. 5μmol/L and 5μmol/L for HCT-116 cells,10μmol/L and 20μmol/L for SW-480 cells,and from 2. 5μmol/L to 40 μmol/L for Caco-2 cells. Conclusion:Atorvastatin could inhibit the growth of colon cancer cells (HCT-116,SW-480 and Caco-2) in a dose-dependent manner;and it could enhance the cytotoxicity of NK cells to colon cancer cells;it also could promote the expression of MICA/B of colon cancer cells,and improve the immunogenicity of colon cancer cells.

Objective To investigate the phenotype and genetic characteristics of a Chinese family with an autosomal-dominant inherited sensorineural hearing loss.Methods A Chinese pedigree associated with an autosomal-dominant inherited low-frequency sensorineural hearing loss (LFSNHL) was investigated.After obtaining informed consent from all study participants medical and audiological examination were used to rule out any syndromic hearing impairment.Five patients were tested with DPOAE and ABR,while two patients were tested with vestibular function and computed tomography scan of the temporal bone to exclude auditory neuropathy and other possible aural disorders.Twenty-one loci and twenty-three genes of DFNA screening had been done by using microsatellite markers and linkage analysis.Results Proband of the family had been diagnosed with low-frequency sensorineural hearing loss.A Chinese family BJ-L046 with non-syndromic autosomal dominant hearing loss was ascertained.Hearing impairment in the affected members in family BJ-L046 occured from 10 to 20 years of age and mainly affected the low frequencies,causing an upsloping audiogram.Higher frequencies were getting involved with increasing age,thus causing a flat-type audiogram.No positive result was found in twenty-one loci and twenty-three genes of DFNA screening.Conclusion A Chinese family with late-onset low-frequency sensorineural hearing loss was clinically studied.No positive result was found by linkage analysis,and twenty-one loci and twenty-three genes of DFNA were preliminary excluded.

Conclusion The training objective of eight-year medical education should be further confirmed.The curriculum should be in accordance with the training objective,and education reform is important and necessary for the eight-year medical education.

Objective （ ） To investigate the association between urinary polycyclic aromatic hydrocarbons PAHs metabolites - Methods and high normal blood pressure in coke oven workers. A total of 433 coke oven workers were selected as the study - subjects using convenient sampling method. They were divided into normal blood pressure group and high normal blood pressure group according to their blood pressure level. The levels of ten kinds of urinary hydroxylated PAHs metabolites were measured by - Results - high performance liquid chromatography mass spectrometry.

Objective To explore the application of hydrogen proton magnetic resonance spectroscopy (1H-MRS) in the diagnosis of peripheral tumor cell infiltration of gliomas. Methods Forty patients with glioma were examined by 1H-MRS preoperation, and were divided into low grade glioma group (n=20) and high grade glioma group (n=20) according to postoperative pathological diagnosis. Tumor resection with peripheral tissues marked previously was carried out under the guidance of neuronavigator system. All the pathological sections were divided into positive group and negative group according to the presence or absence of tumor cells, and the differences in pathological findings of peripheral regions (region 1, 2 and 3) and 1H-MRS values were analyzed in these two groups. Results No infiltration was found in the peripheral regions of low grade glioma group except for one case in peripheral region 1, while infiltration was found in all peripheral regions of high grade glioma group. There was no significant difference in 1H-MRS values between positive group (n=24) and negative group (n=36) in patients with high grade glioma (P>0.05). Conclusion 1H-MRS enjoys some advantages over routine radiological examinations in the diagnosis of peripheral tumor cell infiltration of gliomas. Total removal can be expected when combined with neuronavigator system, while there is room for improvement for relevant techniques.
