Chinese Circulation Journal 2017;32(6):612-616
Objective: To study the influence of different telomere oligonucleotide on rat's thoracic aortic smooth muscle (A7R5 ) cell apoptosis and to clarify weather silent information regulator 1 (SIRT1)/cancer suppressor gene (P53) signaling pathway involved in oligonucleotide induced cell apoptosis. Methods: 3 telomere repeat sequences of TE-12 (TTAGGG)2, TE-24 (TTAGGG)4 and TE-36 (TTAGGG)6 were respectively transfected into rat's A7R5 cells as TE-12 group, TE-24 group and TE-36 group; in addition, blank A7R5 cells were used as Control group. Transfection induced A7R5 cell apoptosis was detected by flow cytometry, mRNA and protein expressions of SIRT1 and P53 in A7R5 cells were examined by RT-PCR and Western blot analysis in different groups. Results: Successful ransfection rates were similar among 3 groups. Compared with Control group and TE-36, TE-24 groups, the highest apoptosis rate of A7R5 cells was found in TE-12 group and the lowest was found in TE-24 group which was still higher than that in Control group, allP<0.05. mRNA and protein expressions of SIRT1 was obviously higher in TE-12 group than the other 3 groups, allP<0.05; mRNA and protein expressions of P53 was obviously lower in TE-24 group than the other 3 groups, allP<0.05. Conclusion: Telomere oligonucleotide sequence may promote rat's A7R5 cell apoptosis; different sequence had various influence and the strongest effect was observed in TE-12 sequence. The above impact might be related to SIRT1/P53 signaling pathway.

Objective To investigate the incidence of adult epilepsy patients with attention-deficit hyperactivity disorder (ADHD) and the characteristics of ADHD subtypes, and to explore the correlations between several epilepsy-related factors and ADHD. Methods According to corresponding inclusion criteria and exclusion criteria, 82 adult epilepsy patients from March 2012 to March 2016 were enrolled as study group. Eighty-two healthy adults were enrolled as the control group. Using the Chi-square test and Logistic regression analysis and the other statistical methods, the phenomenon of ADHD in adults with epilepsy and the factors that may contribute to the phenomenon was analyzed. Results The detection rate of ADHD in 82 adult patients with epilepsy was 26.8%(22/82), significantly higher than that in the heathly control group which was 4.9%(4/82),χ2=18.672, P<0.05. Symptomatic epilepsy 8/17 and the electroencephalogram showed multifocal discharge 6/14 had higher detection rate of comorbid ADHD and the difference was statistically significant (P<0.01). The results of binary Logistic regression analysis showed that epilepsy age of onset was possibly an important factor for epilepsy with ADHD (B=-0.891, P<0.05). Conclusions The risk of ADHD in adults with epilepsy is higher than that in the healthy adults and attention-deficit is the common subtype. The etiology, age of onset and electroencephalogram features of adults with epilepsy may be associated with the occurrence of ADHD.

Objective To explore the clinical features of pulmonary tuberculosis complicated with DM and related factors. Method The manifestations of 87 newly diagnosed PTB patients with type 2 DM(DM-PTB group) at two hospitals in Tianjin during October 2003 to October 2004 were compared to 88 PTB patients without DM who were randomly choosen from the same hosipital.The factors related to sputum-positive TB or cavity were explored through unconditional logistic regression model. Results DM-PTB patients showed significanly lower frequencies of cough(66.7% vs 83.0%),toxicity symptoms(37.9% vs 62.5%) and haemoptysis(16.1% vs 33.0%) than those of PTB group.Positive-sputum(63.2% vs 34.1%),cavity(56.3% vs 13.6%),wide lesions and bilateral lesions on chest radiographs was more common in DM-PTB group than in PTB one.Introversion(OR=1.582, 95%CI:1.063 ~2.355),type 2 DM(OR =2.186,95% CI:1.082 ~4.420)and cavity(OR =2.793,95% CI:1.308 ~5.964)were factors independently associated with positive-sputum TB.The factors related to cavity included diabetes(OR=14.199,95%CI:5.376~ 37.501),cough,postive sputum and lore-up lobe lesion.Conclusion This study confirmed that clinical manifestations and chest radiographs of PTB patients complicated with type 2 DM significantly departed from the typical presentation.Type 2 DM seems to have a negative effect on postive-sputum and cavity.So it should be alarmed that DM-PTB patients who tend to have untypical clinical symptom and higher rate of positive sputum become the reservoirs of infection to cause the transmission of TB.

Background Cataract surgery with replacement of the natural lens with an artificial intraocular lens(IOL) has developed into refractive surgery.Visual acuity is not the only evaluation criterion,but more focus has been put into the visual quality postoperatively.Aspherical IOL could improve the visual quality by decreasing the aspherical aberration.Objective This study was to investigate the short-term visual acuity,aberration alteration and clinical application of unsteady aberration aspheric IOL.Methods A retrospective case-controlled study was designed.Forty-two eyes of 30 patients with age-related cataract were included and divided into two groups.Phacoemulsification combined with unsteady aberration aspheric IOL implantation was performed in 21 cataractous eyes of the ZO group,and phacoemulsification combined with spherical IOL implantation in the other 21 eyes of the ADAPT group.Visual acuity,best corrected visual acuity (BCVA),contrast visual acuity,spherical aberration of the whole eye,contrast sensitivity (CS),dare sensitivity,modulation transfer function (MTF) and apparent accommodation were measured three months after surgery.All the parameters were compared between the two groups.The correlation of CS with the root mean square of spherical aberration,root mean square of comatic aberration and age was analyzed by multiple linear regression analysis.Written informed consent was obtained from each patient prior to operation.Results No significant differences were found in unconnected visual acuity,BCVA and spherical degrees between the ZO group and ADAPT group 3 months after surgery(P>0.05).The CS value in the ZO group was significantly higher than that of the ADAPT group under scotopic background condition with spatial frequencies of 6,12,18 cpd,low glare the spatial frequencies of 6,12 cpd,as well as high glare with 12,18 cpd(P<0.05).Under a scotopic background with 100% contrast or a photopic background with 5% contrast,the contrast visual acuity of the ZO group was significantly higher than that of the ADAPT group (t =20.217,P =0.000 ; t =4.568,P =0.039).At pupil diameters of 3,4 and 5 mm,the Z4 value was significantly lower in the patients of the ZO group than that of the ADAPT group (U =63.000,P =0.000 ; U =52.000,P =0.000 ; U =36.000,P =0.000).However,no significant differences were seen in the Trefoil aberration (Z6)value at 3 mm and 4 mm of pupil diameter(U =204.000,P =0.678;U =215.000,P =0.890) and coma aberration (Z7,Z8) value at 3,4 and 5 mm of pupil diameter between ZO group and ADAPT group(Z7:U=156.000,P =0.159 ; U =196.000,P =0.538 ; U =199.000,P =0.587 ; Z8:U=163.000,P =0.148 ;U=214.000,P =0.870;U =143.000,P =0.061).When the pupil diameter was 5 mm,Z6 value was significantly lower in the patients of the ZO group than that of the ADAPT group (U =4.000,P =0.000).The higher-order aberration MTF was significantly elevated in the ZO group compared with the ADAPT group from 5 through 20 cpd at a pupil diameter of 4 mm (P<0.05) and 10,20,25,30 cpd at a pupil diameter of 5 mm (P<0.05).A slightly lower objective accommodation was found in the ZO group compared with the ADAPT group without statistically significant difference(t =0.003,P>0.05).Multiple linear regression analysis showed that the change in CS was associated with the root mean square of the spherical aberration and IOL type(β=0.544,R2=0.519,P =0.000)rather than with the root mean square of the comatic aberration and age.Conclusions The postoperative visual quality in the unsteady aberration aspheric IOL implanted eye is superior to that in the spherical IOL implanted eye due to a reduction in spherical aberration.
