Objective To research and evaluate measuring Toric intraocular lens (Toric IOL) alignment by iTrace aberration without mydriasis.Methods Forty-five eyes of 35 patients underwent phacoemulsification in Tianjin Medical University Eye Hospital from June 2015 to February 2016 were enrolled.Follow-up and iTrace aberration examination were performed at postoperative 1 week.The internal optics aberration astigmatism axis was transformed into postoperative Toric IOL alignment.The result and the Toric IOL alignment measured by tradition slitlamp method were compared by linear correlation and difference.Results At postoperative 1 week,the uncorrected distant visual acuity and corrected distant visual acuity were (0.19 ± 0.12)LogMAR and (0.10 ±0.09) LogMAR.The UCVA was 20/40 or better in 42 eyes (93.3％).The mean IOL misalignment measured by slitlamp was (3.13 ± 2.86) degrees (ranged 0-9 degrees) and by the iTrace aberration was (4.44 ± 3.42) degrees(ranged 0-13 degrees),there was statistical significant difference (t =-2.321,P =0.025).The mean difference in the error of the Toric intraocular lens alignment measured by iTrace aberration and the slitlamp was (3.67 ± 3.59) degrees (ranged 0-14 degrees).The results showed that there was less than 5 degrees of difference between the two methods in 32 eyes (71.1％),locate 5 to 10 degrees in 9 eyes (20％),more than 10 degrees in 4 eyes (8.9％).The correlation between the 2 methods showed significant linear relationship (r =0.926,P ＜ 0.01).Conclusion Using iTrace aberration can accurately measure Toric intraocular lens alignment without mydriasis,the result has some reference value.

OBJECTIVE To study the efficacyof venlafaxine vs. paroxetine in treatment of peripheral vertigo patients with anxiety and depression. METHODS 180 peripheral vertigo patients with anxiety and depressionwere randomly divided into venlafaxine group(90cases) and paroxetine group(90cases), and were treated respectively for 6 weeks. The patients were assessed by Dizziness Handicap Inventory(DHI), Hamilton Depression Scale24(HAMD) and Hamilton Anxiety Scale(HAMA) before and after the treatment at the 2nd, 4th and 6th week respectively. The clinical efficacy of the two drugs was evaluated according to the reduction rate before and after the treatment. RESULTS Atthe 2ndweek, the scores of HAMA in venlafaxine group was lower than paroxetine groupstatistically(P<0.05). At the 4th week, both the HMAM and HAMD in venlafaxine group were lower than paroxetine groupstatistically(P<0.05). After 6 weeks, The total effective rate of anxiety and depression were 83.33% and 77.78% in venlafaxine group, while 76.67%and 74.45% in paroxetine group. But there was no statistical difference(P>0.05). The scores of DHI were decreased in both groups(P<0.05), and index p in venlafaxine group was lower than paroxetine group(P<0.05). CONCLUSION Both of them can reduce the physical symptoms and dysfunction, are effective on anxiety and depression, but venlafaxine is faster to take effect than paroxetine, and has a better patient compliance.

Objective To investigate the accuracy of predicting middle cerebral artery infaction with contin -ue electroencephalograph .Methods 40 cases with middle cerebral artery infaction were divided into malignant groups(14) and binigan groups(26).They were all with continued beside electroencephalograph within 24 hours after admission.Results Abnormal CEEG rate in malignant groups [85.71%(12/14)]was significantly higher than that in binigan groups[65.38%(17/26)](χ2 =10.405,P=0.001).In malignant groups,severe abnormal CEEG was seen in 4 cases developed coma at the second day of admission ,moderate abnormal CEEG was found in 6 cases,slight abnormal CEEG was detected in 2 cases,normal CEEG was detected in 2 cases.Conclusion Early CEEG has a cer-tain value for predicting middle cerebral artery infaction .

Objective To investigate the clinical significance of prenatal ultrasound examination in the diagnosis of fe?tal digestive tract development. Methods Twenty-nine cases of congenital digestive tract malformation were examined in according to the different characteristics of their different fetal ultrasound images. Results There were 11 cases with non-magenblase or less magenblase (37.93%), 4 cases with combination of multiple malformations, and 9 cases with combination of amniotic fluid in the 29 cases. There were 7 cases (24.14%) with dilatation of intestine and intestinal vesicles, in which 3 with multiple malformations and 3 with polyhydramnios. There were 8 cases (27.58%) with double bubbles, in which 1 case with multiple malformations and 7 cases with amniotic fluid. Conclusion The prenatal ultrasound examination in 30 to 32 weeks of pregnancy is very valuable in diagnosis of fetal digestive tract development, which is worthy of clinical application.

Apoptosis of dopaminergic neurons in the nigrostriatal projection plays a crucial role in the pathogenesis of Parkinson's disease (PD). Although the detailed mechanisms responsible for dopaminergic neuron loss are still under investigation, oxidative stress is identified as a major contributor for neuronal apoptosis. In the current study, we studied the effects of MPP(+), a substrate that mimics oxidative stress, on neuron-like PC12 cells and the underlying mechanisms. PC12 cells were cultured and treated by 100 μmol/L MPP(+) for 4, 8, 16, 24 and 48 h, respectively. For drug pretreatment, the PC12 cells were incubated with N-acetyl-l-cysteine (NAC, 5 mmol/L), an antioxidant, SP600125 (20 μmol/L) or PD98059 (100 μmol/L), two pharmacological inhibitors of JNK and ERK1/2, for 1 h before addition of MPP(+). Cell apoptosis was measured by flow cytometry. The mRNA expression of Cu(2+)/Zn(2+)-SOD, GSH-Px, Bcl-2 and Bax was detected by RT-PCR. The protein expression of p-ERK1/2 and p-JNK was determined by Western blotting. Our results showed that MPP(+) exposure could induce substantial PC12 cell apoptosis. The pretreatment of SP600125 or PD98059 could effectively reduce the apoptosis rate by reducing the ratio of Bax/Bcl-2 mRNA levels. MPP(+) exposure also induced high level of reactive oxygen species (ROS), marked by dramatic increase of Cu(2+)/Zn(2+)-SOD and GSH-Px mRNA levels. The elevated ROS was strongly associated with the activation of JNK and ERK1/2 signal pathways after MPP(+) exposure, since the pretreatment of NAC significantly reduced the upregulation of p-JNK and p-ERK1/2. Finally, the pretreatment of SP600125, but not PD98059, alleviated the increase of Cu(2+)/Zn(2+)-SOD and GSH-Px mRNAs induced by MPP(+), suggesting that the activation of the JNK signal pathway, but not the ERK1/2 signal pathway, could, in some degree, antagonize the generation of ROS induced by oxidative stress. In conclusion, our results suggest that JNK and ERK1/2 signal pathways, which are activated via ROS, play a crucial role in neuronal apoptosis induced by oxidative stress.

Objective To explore the effect of levels and ratios of matrix nephritis metalloproteinase-2(MMP-2), -9 and inhibitor of metalloproeinase-1(TIMP-1) in the pathogenesis of children with Henoch-Schonlein purpura nephritis(HSPN),and the correlation between them and urinary micro albumin(MA).Methods Serum levels of MMP-2, -9 and TIMP-1 were determined by double antibody enzyme linked immunosorbent assay(ELISA),and urine MA was determined by immune rate nephelometry in 36 children with HSPN,16 children with simple purpura and 30 healthy controls.Results Levels of MMP-2, -9,TIMP-1 and ratios of MMP-2/ TIMP-1,MMP-9/TIMP-1 rose in acute phase of HSPN. The levels and ratios in HSPN group were higher than those in simple purpura group,and those in simple purpura group higher than those in controls (P

OBJECTIVEThe objective of this study is to study the distribution and molecular characteristics of the oral Saccharomyces albicans (S. albicans) in the cancer patients receiving chemotherapy.

METHODS390 cancer patients receiving chemotherapy were sampled by oral mucosal swab. The Candida species were identified by CHROMagar Candida differential medium. All the S. albicans were genotypic grouped by PCR using primers reported to span a transposable intron region in the 25S rDNA gene.

RESULTSThe frequency of oral Candida carriage of the cancer patients receiving chemotherapy was 53.85% (210/390). Most of them were Saccharomyces albicans, the frequency was 48.21% (188/390). The frequency of oral Candida glabrata carriage was 5.64% (22/390). Genotypic subgroup A, B, C of Saccharomyces albicans were determined, and genotypic group B was the predominant group 59.57% (112/188).

CONCLUSIONSaccharomyces albicans, especially genotypic subgroup B, rather than subgroup A, is the prevalence subpopulation in the oral Candida obtained from cancer patients receiving chemotherapy.
