ObjectiveTo explore the influences of parental rearing pattern and adult attachment on narcissism of college students.Methods 344 college students from two universities in Hebei Province were sampled randomly and tested by the Chinese version of EMBU,the Narcissistic Personality Inventory and the Experiences in Close Relationships Inventory (ECR) in Chinese version.Results ( 1 ) The whole score of overt narcissism correlated with paternal warming,punishment,interference,rejection and maternal warming( r =0.163,0.130,0.184,0.109,0.206),but not with adult attachment; covert narcissism correlated with paternal punishment,over-interference,rejection,over-protection,maternal over interference and protection,rejection,and punishment,and anxiety and aviodance of adult attachment positively ( r =0.135,0.169,0.210,0.123,0.220,0.194,0.215,0.183,0.269).(2) The parental reaming pattern affected overt narcissism directly,while that affected covert narcissism directly with adult attachment,and indirectly through adult attachment.ConclusionCotraditory rearing patterns between father and mother lead to overt narcissism,and negative rearning patterns lead to covert narcissism with the mediator role of adult attachment.

Objective To explore the difference of social support,self-esteem and marital quality between urban and rural areas and discuss the impact on each other.Methods Chinese marital quality questionnaire,selfesteem scale (SES) and social support rating scale were used to test 386 urban and rural married residents.Results ①The results of descriptive statistics showed that marriage quality,social support and self-esteem of urban and rural residents were (318.46±37.41),(42.44±5.84) and (30.65 ± 3.95) respectively.②There was no significant difference among social support,self-esteem and marital quality in different gender(t =0.41,-0.16,0.03,P＞ 0.05),but had significant difference between urban and rural areas(t=2.83,3.91,5.24,P＜0.01).There were significant differences between social support and marital quality in different age structures(t=5.22,3.85,P＜0.05).There were significant differences between social support and self-esteem in different educational level (t =3.48,4.16,P＜0.01).③Social support,subjective support,objective support and marital quality had positive correlation (r=0.114～0.394,P＜0.05).The degree and character compatibility,communication between couples,resolve conflicts are positively related to support (r=0.308～ 0.476,P＜0.01).④Stepwise multiple regression analysis and structural equation modeling analysis showed that self-esteem played partial intermediary role between social support and marital quality(37.7％),which could explain 26.8％ of marital quality.The social suptort and self-esteem could better predict marital quality.Conclusion The higher social support and self-esteem are,the higher marital quality is.Social support can directly affect the marital quality and indirectly affect marital quality through self-esteem.

Objective:To determine the molecular role of DNA methyltransferase (DNMT) in kidney tumorigenesis. Methods:Tissue samples consisted of 15 cancer tissues and 15 matched adjacent tissues from clear cell renal cell carcinoma (ccRCC) patients who had undergone nephrectomy in 2012 at the First Affiliated Hospital of Baotou Medical College, Science and Technology University of Inner Mongolia were collected. Real-time PCR, Western blot, combined bisulfite restriction analysis (COBRA) and methylation specific PCR were used in this study. Real-time PCR was used to examine the mRNA expression levels of DNMT. The global methylation level, DNA methylation level, and the expression of the antioncogene RASSF1A in ccRCC tissues were concurrently detected. Results:Both mRNA and protein levels of DNMT3B4, a splice variant of DNMT3B, were elevated in renal cell carcinoma tissue compared with those in con-troll tissue. Additionally, Alu was hypomethylated in ccRCC tissue (0.106±0.04) compared with control tissue (0.115±0.03) (P<0.05). Fur-thermore, the methylation of the promoter for RASSF1A, a tumor-suppressor gene, moderately increased in renal cell carcinoma tis-sue. By contrast, RASF1A expression decreased. Conclusion:DNMT3B4 overexpression may play an important role in human kidney tu-morigenesis via chromosomal instability and the decreased expression of RASSF1A.

Background The simplex congenital blepharoptosis is the common blepharon motor dysfunction disease.Some researches have shown that congenital blepharoptosis is related to the hypoplasia of levator.Objective This study was to investigate the thickness and pathological features of levator palpebrae superioris aponeurosis in congenital blepharoptosis patients.Methods A prospective cohort study was carried out in Anyang Eye Hospital from March 2012 to April 2014.Eighty-five eyes of 56 patients with congenital blepharoptosis were divided into mild (15 eyes), moderate (25 eyes) and severe blepharoptosis (19 eyes) groups, and the fellow eyes of monocular blepharoptosis was used as fellow eye group (26 eyes).Twenty-six eyes of 13 normal subjects were recruited for the normal control group.The thickness of levator aponeurosis was measured by ultrasound biomicroscope (UBM) , and the shifting range of levator aponeurosis was detected by using measuring scale.Levator aponeurosis specimens were collected during the levator palpebrae superioris shortening surgery for the pathological examination.The study was approved by the medical ethics committee of Anyang Eye Hospital, and the patients or their guardian signed the informed consent.Results The thickness of levator aponeurosis was (0.331±0.018), (0.373±0.026), (0.539± 0.023) , (0.557 ± 0.024) and (0.547 ± 0.028) mm in the severe blepharoptosis group, moderate blepharoptosis group,mild blepharoptosis group, normal control group and fellow eye group, respectively, showing a significant difference among them (F =1.681, P =0.043).The thickness values of levator aponeurosis were considerably lower in the severe blepharoptosis group and moderate blepharoptosis group than those in the mild blepharoptosis group,fellow eye group and normal control group (all at P＜0.05) , and the thickness value of levator aponeurosis was significantly reduced in the severe blepharoptosis group compared with the moderate blepharoptosis group (P＜0.05).Pathological examination showed arranging disorder of muscle fibers,hyaline-like degeneration, connective tissue hyperplasia and interruption of endomysium.The number of eyes with severe hyaline-like degeneration and connective tissue hyperplasia was significantly increased in the severe blepharoptosis group than that in the moderate blepharoptosis group or the mild blepharoptosis group, as well as in the moderate blepharoptosis group than that in the mild blepharoptosis group(all at P＜0.01).The adipose cells in muscle in the mild blepharoptosis group, moderate blepharoptosis group and severe blepharoptosis group were (12.35±4.62), (17.58±7.46) and (26.19±10.81)/field,and adipose cells in the severe blepharoptosis group were significantly more than those in the mild and moderate blepharoptosis groups (t =5.60, P =0.00;t =2.71, P =0.01).A significant increase in the adipose cells also was seen in the moderate blepharoptosis group compared with the mild blepharoptosis group (t =2.44, P =0.02).Conclusions UBM can offer accurate thickness data of levator aponeurosis.The combination of thickness data and shifting range measurement of levator aponeurosis is helpful for the evaluation of muscle strength.The development of levator aponeurosis appears to be abnormal in congenital blepharoptosis patients.The histopathological change parallels to the severity of the disease.

Objective To study the effects of AuNPs@PEG-AS1411 nanoparticles on radiosensitization of human uterine cervix cancer HeLa cells.Methods AuNPs were synthesized by citrate reduction method and then functioned with PEG and PEG-AS1411, respectively.CCK-8 assay and colon forming assay were used to detect the acute and chronic toxicity effects of AuNPs on HeLa cells, respectively.At the same time, clonogenic survival assay was applied to measure the cell survival rate of HeLa cells after exposure to AuNPs@PEG and AuNPs@PEG-AS1411 combined with X-ray radiation.The intracellular uptake of AuNPs@PEG and AuNPs@PEG-AS1411 in HeLa cells were detected by ICP-MS.Results The CCK-8 assay showed that AuNPs@PEG and AuNPs@PEG-AS1411 were not toxical on HeLa cells(P ＞0.05).But the clonogenic survival assay showed that AuNPs@PEG and AuNPs@PEG-AS1411 had toxicity on HeLa cells significantly after 10 d(t =4.38-11.60, P ＜ 0.05).AuNPs functioned with AS1411 could increase the cellular uptake of AuNPs.AuNPs@PEG and AuNPs@PEG-AS1411 both had significant radiosensitive effect on HeLa cells (F =7.90,48.23, P ＜ 0.05).The values of SERDo for AuNPs@PEG and AuNPs@PEG-AS1411 were 1.12 and 1.20, respectively, when the concentration of Au was 10 mg/L.Conclusions AuNPs@PEG and AuNPs@PEG-AS1411 could cause chronic toxicity on HeLa cells instead of acute effect.PEGylated AuNPs functioned with AS1411 could enhance the radiosensitivity of HeLa cells in vitro.

Objective To investigate the technique and application of nasolacrimal duct imaging using MR hydrography.Methods Eight healthy volunteers(16 lacrimal ducts)and 17 patients affected by primary epiphora(32 lacrimal ducts)underwent MRl with three.dimensional fast recovery fast spin echo (3D-FRFSE)MR dacryocystography(MRD)sequence after sterile saline solution had been instilled into the conjunctival sac.For all patients affected by primary epiphora,FRFSE T2-weighted oblique coronal and axial images were obtained after MRD.All patients(32 lacrimal ducts)underwem lacrimal endoscopy.which served as a standard of reference for confirming MR findings.Results Eight cases of 16 normal lacrimal passages were showed by MR hydrography with administering topical sterile saline solution,which demonstrated the lacrimal sac well and whole course of the nasolacrimal duct.Endoscopic findings confirmed nasolacrimal duct obstruction secondary to chronic non-specific inflammation:the color of the mucosa of the nasolaerimal ducts was grey-red,and the obstructive sinuses were filled with nonelastic grey-white membrane.The accuracy of 3D-FRFSE MRD sequence in diagnosing obstructive level was 78%(25/32). The lacrimal ducts above the obstructive level showed watery hypo-intensity on 3D-FRFSE MRD.and the lacrimal ducts below the obstructive level could not be showed.Abnormal findings were presented in all cases of obstructive nasolacrimal ducts with Axi-FRFSET2 WI and Cor-FRFSET,WI sequences:long T2 fluid signals were seen in the lumens of tlle lacrimal sac and(or)nasolacrimal duct above the obstructive level. equal or slightly long T2 soft-tissue signals were seen in the lumens of the nasolaerimal duct below the obstructive level.and the mucosa of the ducts thickened Conclusion MR imaging performed after the topical administration of sterile saline solution can reveal normal nasolacrimal duct and is feasible in evaluating obstructive nasolacrimal ducts.

Objective To evaluate the association of COX2 genetic variants with the risk of esophageal cancer and the interaction of COX2 genetic variants with Hp infection. Methods A total of 119 patients with esophageal cancer and 238 frequency-matched controls were genotyped by polymerase chain reaction-restriction fragment length polymorphism method. Odds ratios (OR) and 95% confidence intervals ( CI) were estimated by logistic regression. Results Case-control analysis showed an increased risk of developing esophageal cancer for 1195 GA(OR =2.69,95% CI= 1. 46-5. 14) and 1195AA ( OR = 2. 30,95% CI = 1.23-4. 89) genotype carriers,respectively, compared with non 1195 GG carriers. When stratified by Hp status, the significantly increased risk of esophageal cancer was found among Hp carrier with OR (95%CI) =2.74 (1.35-5.96) ,but not among Hp non-carriers. Conclusion Genetic polymorphism in COX2 promoter region may play an important role in esophageal cancer by Hp infection.

To explore the role of the Chk2 protein expression and DNA double strand breaks (DSBs) repair in low dose hyper-radiosensitivity (HRS)/increased radioresistance (IRR) of non-small cell lung cancer, A549 cells were subjected to irradiation at the dosage ranging from 0.05-2 Gy. Clonogenic survival was measured by using fluorescence-activated cell sorting (FACS) plating technique. Percentage of cells in M-phase after low doses of X-irradiation was evaluated by phospho-histone H3-FITC/PI and Western blotting was used to detect protein expression of Chk2 and phospo-Chk2. DNA DSBs repair efficiency was also measured by induction and persistence of γ-H2AX. The results showed that the killing ability of irradiation with A549 cells increased at low conditioning dose below 0.3 Gy. Within the dose of 0.3 to 0.5 Gy, A549 cells showed a certain extent of radiation resistance. And when the dose was more than 0.5 Gy, survival fraction exhibited a negative correlation with the dosage. There was no difference between the 0.1 or 0.2 Gy dosage groups and the un-irradiated group in terms of the percentage of cells in M phase. But in the high dosage group (0.3-1.0 Gy), the percentage of cells in M phase was decreased markedly. In addition, the percentage of cells in M phase began to decrease two hours after irradiation. One hour after irradiation, there was no conspicuous activation of Chk2 kinase in 0.1 or 0.2 Gy group, but when the irradiation dose reached 0.3 Gy or higher, Chk2 kinase started to be activated and the activation level showed no significant difference among high dosage groups (0.4, 0.5, 1.0 Gy). Within 1 to 6 h, the DNA DSBs repair efficiency was decreased at 0.2 Gy but increased at 0.5 Gy and 1.0 Gy, which was in line with Chk2 activation. We are led to conclude that the mechanism of HRS/IRR in A549 cell line was probably due to early G(2)/M checkpoint arrest and enhanced DNA DSBs repair. In this regard, Chk2 activation plays a key role in G(2)/M checkpoint activation.

Background The clinical effectiveness of soft corneal contact lens for correction of myopia has been confirmed.Theoretically,aspherical soft hydrophilic corneal contact lens has better visual qualify for myopic eyes,and the lenses have been applied widely.But abnormal tear film,even many cornea and conjuctiva diseases caused by soft contact lens have been reported,so the effectiveness and safety of aspherical soft hydrophilic corneal contact lens are worth concerning.Objective This clinical trail was to compare the effectiveness and safety between aspherical and NUV soft hydrophilic contact lens for myopic eyes.Methods A randomized,double-blind and controlled clinical study was performed under the approval of Ethic Committee of Qingdao Municipal Hospital and informed consent of each patient.One hundred and forty eyes of 70 myopic patients were enrolled in QingdaoMunicipal Hospital from July to October,2012.The subjects were randomized into the trial group and control group using random number table.Aspherical soft hydrophilic contact lenses were worn in the trial group and NUV soft hydrophilic contact lenses were worn in the control group.The characteristics of the lens surface,outcomes and the eye number in different scores of ocular signs and symptoms were assessed before and 15 minutes,1 week,2 weeks and 1 month after wearing lenses.Results The sores of humidity of anterior surface,the sediment in anterior and posterior surface are 0 in both lenses in various time points after wearing.The corrected visual acuity of all the subjects were ≥ 1.0.The eye number of 2-3 scores in various ocular signs was 0 in both groups,but the eye number of 1 score in palpebral conjunctival congestion and limbus congestion were more in the trail group than those in the control group in different time points (all at P＜0.05).There were significant differences in corneal fluorescine staining between the groups in different time points (all at P＞0.05).There was no eye for 2-3 scores of eye symptoms in both groups.The eye number for 1 score in foreign body sensation increased in the target-trail group compared to the control group at various time points (P =0.002,0.006,0.005,0.005).However,there was no statistically significant differences in the eye number for 1 score in visual clearness and stability between the two groups at the follow-up duration (all at P＞ 0.05).Conclusions Aspherical soft hydrophilic corneal contact lens has good outcomes in corrected visual acuity for myopia like NUV soft hydrophilic contact lens,but the wearing of aspherical soft hydrophilic corneal contact lens induces more ocular discomfortableness.

Objective To construct two vectors of small interfering RNA (siRNA) expressing α-Fodrin and investigate its therapeutic effects on mice model with primary Sj(o)gren's syndrome (non-obese diabetic mice,NOD mice).Methods Sixteen 8-week-old NOD mice were randomly divided into four groups:the control group,the vector group,the α-Fodrin-siRNA1 group and α-Fodrin-siRNA2 group,4 mice in each group.Four template DNA of α-Fodrin siRNA were chemically synthesized and annealed to two double stranded (dsDNA),then digested by BamH Ⅰ and Hind Ⅲ.The digested double strands oligos were inserted into the downstream of U6 promoter of linearized pGFP-V-RS vector.Recombinant were confirmed by restrictive enzyme digestion and sequencing.Then the vectors were injected throughtail veil once a week,two times in total,while mice in the control group were injected with the same dose of phosphate buffer saline (PBS)and the vector group were injected with the same dose of vector vehicle.pGFP-V-RS was labeled by green fluorescent protein(GFP) and lacriminal glands underwent pathological examination.In addition,the expression of α-Fodrin mRNA in lung were detected by reverse transcription-polymerase chain reaction (RTPCR),and α-Fodrin protein in lacriminal glands and lung were detected by immuno-histochemistry.Serum interferon (IFN-γ),interleukin-17 (IL-17) concentrations in each group were detected by enzyme linked immunosorbent assay (ELISA) in order to observe changes in cytokine levels.At the same time,the pathological changes of the lacriminal glands and organs with hematoxylin-eosin (HE) staining were observed.The repeat ANOVA was used for statistical analysis.Results ① We constructed two siRNA eukaryotic expression vector successfully; ② α-Fodrin-siRNA could target to the lacriminal glands.③ Compared with the control group and vector vehicle group,the expression of α-Fodrin mRNA and protein were significantly decreased in the treatment groups.④ Compared with the control group [(11.73±2.73) pg/ml] and vector vehicle group [(15.40±1.99) pg/ml],serum IL-17 levels in the treatment groups were [α-Fodrin-siRNA 1 group (4.38±1.02) pg/ml; α-Fodrin-siRNA 2 group (4.55±0.06) pg/ml] significantly decreased (P＜0.05),but IFN-γ levels in the αt-Fodrin-siRNA group were not decreased significantly (P＞0.05).⑤ Compared with the control group and vector vehicle group,lymphocyte infiltration of lacriminal gland and inflammatory cell infiltration of alveolar and interstitial were significantly reduced in α-Fodrin-siRNA groups.Conclusion Specific α-Fodrin siRNA can inhibit the inflammation,and suppress the inflammatory infiltration of lacriminal glands and lung in mice with primary Sj(o)gren's syndrome.So the constructed vectors may slow the progression of pSS.
