Objective: To compare the difference of self-concept between children of complete and divorced family. Methods: 42 subjects in divorced family and 45 controls were tested by Piers-Harris Self-concept Scale for Children. Rusults: The students in divorced family reported significantly lower scores on self-concept than the controls on behavior,anxiety, gregariousness, satisfaction and total score. Conclusion: The self-concept of divorced family students is lower than that of the control group.

Objective To describe the prevalence and distribution of anxiety disorders among people aged 18～65 yrs in Liaoning Province. Methods 15 518 subjects in 7 200 families aged 18～65 yrs were randomly selected from 3 cities and 3 counties by multi-stage stratified random cluster sampling.They were assessed for DSMⅢ-R diagnoses by face to face interview with Composite International Diagnostic Interview(CIDI-1.0). Results There were 13 359 subjects had finished the survey,and the response rate was 86.09%.The 2-week,12-month and lifetime prevalence of anxiety disorders were 2.22%,4.60% and 7.21% regulated by Liaoning provincial population in 2000,and1.91%,3.97%and6.32% regulated by countrywide population in 2000.The major disorders were specific phobia and agoraphobia,and their lifetime prevalence were 3.80% and 3.04%,respectively.The people with higher prevalence were females,aged 25~55,with lower educational and economic level. Conclusion Anxiety disorders become a serious public health problem in Liaoning province.Prevention measures should be taken among people with high risk.

Objective Early clinical symptoms of esophageal cancer are often not obvious , so a deeper insight into tumor markers is very important for the early diagnosis of esophageal cancer .This study was to investigate the expressions of Rock 2 and Wnt11 in the specific esophageal cancer cell lines Eca-109 and HEEC and the relationship of the signal transduction pathway of proteins with the development of esophageal cancer . Methods Esophageal cancer cell lines Eca-109 and HEEC were cultured and the expression levels of Rock2 and Wnt11 in the cell lines were determined by real-time quantitative PCR and Western blot . Results The mRNA expressions of Rock2 and Wnt11 were significantly increased in the Eca-109 as compared with those in the HEEC cell line (4.955± 0.539 vs 1.000±0.000, P<0.01;2.925±0.230 vs 1.000±0.000, P<0.01), and so were the protein expressions of Rock 2 and Wnt11 (955.000±21.628 vs 778.844±102.193, P<0.05;2175.316±145.623 vs 1312.233±50.734, P<0.05). Conclusion The up-regula-ted expressions of Rock 2 and Wint11 may be the markers of the metastasis of esophageal squamous cancer .

Objective To obtain the recombinant urease B subunit (ureB) of Helicobacter pylori (Hp) and apply it in serological detection of Hp infected patients. Methods Urease B subunit gene was amplified from the complete genome of Helicobacter pylori by PCR, and cloned into the PinPoint TM Xa Ⅲ fusion expression vector, then was sequenced. The protein of urease B subunit was expressed in E.coli JM109 and purified with affinity chromatography. 113 serum samples of peptic ulcer patients were detected by ELISA combined with purified UreB protein. Results DNA sequence analysis showed the nucleic acid sequence homology of ureB gene was 96.44% and the putative amino acid sequence homology was 99.65%. The recombinant UreB protein was composed of 571 amino acid residues and kept original immunologic reaction with corresponding antibody, and its purity was over 90% after affinity chromatography. The results of ELISA associated with recombination UreB antigen showed the sensitivity and specificity was 92%, 98.5%. Conclusion The recombinant UreB protein will be of value for clinical serodiagnosis and epidemiological study of Helicobacter pylori.

Objective To investigate whether tolterodine combined with pelvic floor electrical stimulation is more effective than tolterodine alone in the treatment of wonen with overactive bladder(OAB) and the underlying mechanism.Methods Seventy-three female patients with OAB were recruited from our hospital during Oct.2009 to Dec.2010 and prospectively studied,of whom 39 cases were given tolterodine(2 mg each time,twice daily for4 weeks)alone while the other 34 cases were given tolterodine combined with pelvic floor electrical stimulation for the treatment of OAB.Data on urgency,incontinence,micturition frequency,nocturia episodes and voided volume were collected before and after 4 weeks' treatment using a week micturition diary.Results The differences of changes of OAB symptoms between the 2 groups had statistical significance (P ＜ 0.05).Patients in the tolterodine combined with pelvic floor electrical stimulation group reported treatment benefit than the tolterodine group in the micturitions and the volume voided per micturition(P ＜ 0.05).There were no difference in the number of urgency episodes per 24 hours,incontinence episodes and nocturnal episodes (P ＞ 0.05).Conclusion A combination of toterodine with pelvic floor electrical stimulation could significantly improve the OAB symptoms,and is a potential therapy for female patients with OAB.

Objective To investigate the association between gene polymorphism of sortilinrelated receptor 1 (SORL1) and Alzheimer' s disease by detecting a series of single nucleotide polymorphisms (SNPs).Methods The Snapshot method was used to genotypc 6 SNPs (SNP10,19,23,24,25,27) in SORL1 and the distributions of allele and genotype of the 6 SNPs were compared between AD patients and healthy control individuals.Results There were significant differences in the genotype distributions of SNP19,23,24 and 25 between AD patients and control group (all P＜0.01).Subjects with TT genotype in SNP19 had significantly lower risk for AD and was protective for AD (OR=0.089,95％CI:0.011-0.718,P＜0.01).The AT genotype in SNP23 (OR＝3.826,95％CI:1.388～10.544,P＜0.01),CT genotype in SNP24(OR=5.935,95％CI:1.774-19.853,P＜0.01)and CT genotype in SNP25(OR=5.754,95％CI:2.007-16.496,P＜0.01)had higher risks for AD.Conclusions SORL1 gene variants of SNP19,23,24 and 25 might be the important risk factors for late-onset AD.

Objective To observe the alteration of skin complexion after UVA and UVB exposure.Methods The back skin of ten females with skin type Ⅲ was subjected to single exposure to solar-simulated UVA of double minimal persistent pigment darkening (MPPD) or UVB of double minimal erythema dose (MED). Skin reflectance was assessed with clinical grading, spectcolometer and Mexameter MX 18 before irra-diation, 6 hours, 1, 7 and 14 days after the irradiation. Results After UVB irradiation, a~* value and erythema index (EI) abruptly increased at 6 hours and peaked on day 2; L~* value sharply declined on day 1; ITA° markedly decreased on day 7; melanin index (MI) declined within the first 2 days, but notably increased on day 7. After UVA irradiation, a~* and El value experienced no apparent changes; L~* value obviously declined at 6 hours; ITA° reached its lowest value on day 14; MI increased only on day 1. Conclusions There is a significant difference in the kinetics and extent of skin complexion changes after UVA and UVB irradiation. EI and a~* value are sensitive and accurate indices for evaluating sunburn, and MI and ITA ° for analyzing tanning.

Objective To determine the incidence of lung infection and associated factors in patients with traumatic brain injury for the sake of improving the clinical outcomes.Methods A retrospective analysis was made on records of 325 patients who hospitalized between January 2014 and June 2014.There were 198 male and 127 female patients,aged 11-78 years [(38.4 ±8.3) years].A total of 172 patients were injured in traffic accidents,80 in high falls,56 in blow accidents,and 17 in others.Lung infection status was documented and related risk factors were analyzed.Results Thirty-two patients (9.8％) had lung infection.Pseudomonas aeruginosa amounting to 12 strains was the most common pathogenic bacteria.Univariate analysis showed mechanical ventilation,airway open,and aspiration were significantly related to lung infection.Logistic regression identified aspiration (OR =2.891,P ＜ 0.05) and mechanical ventilation (OR =1.323,P ＜ 0.05) as the independent risk factors for lung infection.Conclusions Lung infection is a serious complication of traumatic brain injury,affected largely by aspiration and mechanical ventilation.Active preventions,reductions of risk factors,and early treatments should be done to get the best efficacy.
