Objective To explore a new project-integrated teaching method and evaluate its effect in the course of optometry special examination techniques. Methods Class Three of Optometry 2011 was chosen as experimental group and used the new project integrated teaching method while Class Four was chosen as control group and used traditional teaching method , both class having 30 students. After the end of the course the students of both class were assessed the theoretical knowledge and operating skills of the same standard. The self-designed questionnaire was used to investigate stu-dents' self evaluation of the teaching effect. After students of both groups practiced in the same depart-ment of ophthalmology optometry clinic special inspection post for half a year, teachers' evaluation of the students' training performance was collected. Final examination scores, experimental examination scores and the teachers' evaluation scores of the two groups were compared by t-test respectively and the self-assessment results of the students of both groups were compared by chi-square test. Results The final examination and experimental examination scores of the experimental group were both higher than those of the control group significantly(P=0.001,0.002 respectively). The experimental group students had a significantly better self-assessment than the control group in learning interest ( P=0.007), understanding(P=0.046), self-learning ability(P=0.000), summary ability(P=0.009), ana-lytical ability(P=0.000) and innovation ability(P=0.000). The clinical teachers' evaluations of the ex-perimental group were better than the control group. The differences were statistically significant in standardization of practice, application ability, examination report reading ability and case analytical ability(P=0.000). Conclusion The project-integrated teaching method can help to improve the students' leaning motivation and cultivate students' autonomous learning ability and comprehensive analysis capa-bility and so on, which is helpful to reaching a good teaching effect and ensuring the teaching quality.

Objective To explore the diagnostic value of 18F-FDG PET/CT in the inflammatory bowel diseases (IBD).Methods The clinicopathological data of 75 patients(46 males,29 females;average age 38 years) with IBD confirmed by colonoscopy from March 2010 to March 2014 were reviewed retrospectively.Among the 75 patients,30 were with ulcerative colitis(UC) and 45 were with Crohn's disease (CD).All underwent whole-body 18F-FDG PET/CT imaging.Enteroscope and CRP examination were performed within 1 week before or after PET/CT imaging.The results of 18F-FDG PET/CT were compared with those of located CT and enteroscope (x2,t tests).Linear correlation analysis was used to analyze the relationship between CRP and the SUVmax of lesions presented in IBD.Results (1) 18 F-FDG PET/CT accurately detected 65 patients with IBD,while located CT diagnosed 55 patients with IBD.The diagnostic sensitivities were significantly different:86.7％ (65/75) vs 73.3％ (55/75),x2 =4.167,P＜0.05.(2) Among 65 patients with positive results in 18F-FDG PET/CT,lesions were consistent with those detected by endoscopy in 33 (33/75,44.0％)patients.Results of the 2 methods in 24 patients (24/75,32.0％)were not completely same,those in 8 patients (8/75,10.7％)were totally different.18F-FDG PET/CT detected 145 lesions,while enteroscope only detected 119 lesions.Diffuse high FDG uptake was shown in intestinal wall in 40 of 65 patients,and mild mucosa injury was showed by enteroscope in 18 patients (45.0％,18/40).(3)Fortyeight of 65 patients detected by PET/CT were proven clinically to be in active stage,and the rest were in stable stage.The SUVmax of active stage group (8.31±4.21) was significantly higher than that of the chronic stage group (6.36±3.15;t =2.033,P＜0.05).There was a linear correlation between CRP and SUVmax of patients in active stage(r=0.453,P＜0.01).Conclusions 18F-FDG PET/CT is helpful to assess the activity of IBD and may serve as a supplementary diagnosing tool to detect the lesions under the epithelium of bowel,which are often false-negative by enteroscope.

Objective To study the chemical constituents from the stems of Marsdenia tenacissima.Methods The chemical constituents were isolated by various column chromatography and their structures were identified by spectral and chemical analysis.Results Two pregnane glycosides were isolated from the stems of M.tenacissima and identified as3-O-β-D-glucopyranosyl-(1→4)-6-deoxy-3-O-methyl-β-D-allopyranosyl-(1 →4)-β-D-oleandropyranosyl-11α-Otigloyltenacigenin B,named as tenacigenoside I(1)and 3-O-β-D-glucopyranosyl-(1→4)-6-deoxy-3-O-methyl-β-Dallopyranosyl-(1→4)-β-D-oleandropyranosyl-11α,12β-di-O-acetyltenacigenin B,named as tenacigenoside K(2).Conclusion Compound 1 is a new compound,1H-NMR and 13C-NMR data of compound 2 are reported for the first time.

Objective To study the correlation between marital adjustment and personality characteristics in infertile patients. Method The Locke-Wollance marital adjustment measurement scale and Eysenck personality questionnaire(EPQ)were used among 156 patients with infertility to investigate the correlation between marital adjustment and personality characteristics in infertile patients. Results The total score on the marital adjustment was(100.7±15.5). The rate of good marital adjustment was 51.3%and the rate of marital maladjustment was 48.7%. Those with a marital time of shorter than 5 years were better at marital adjustment compared to those with more than 5 years adjustment(P<0.01). In the characteristics of personality,the items of psychoticism(P)and neuroticism(N)fell at the mode of propensity. The scores on introversion and covering were at the middle level. The groups between the marriage age of shorter than 5 years and more than 5 years were significantly different in psychoticism,introversion and extroversion and nervousness(P<0.01). The marital adjustment were negatively correlated with psychoticism and nervousness,but positively correlated with extraversion. The marriage adjnstmc-nt were positively correlated to cpsychoticism and nervousness,but postively correlated with extroversion. The marriage age was positively correlated with psychoticism and nervousness,but negatively related to extraversion and covering with statistically significant difference (P<0.01).Conclusions In the infertile patients,there are many cases of family marriage disorder. The marriage adjustment and age can affect the personality traits of infertile patients. It indicates that infertility affects the physical and mental health.

Objective: Combined detection of anti-mutated citrullinated vimentin ( anti-MCV ) antibodies, anti-cyclic citrullinated peptide ( anti-CCP) antibodies and rheumatoid factor ( RF-IgM) levels to investigate the diagnostic value of anti-mutated citrullinated vimentin (anti-MCV) antibodies for rheumatoid arthritis(RA).Methods: A total of 359 patients with RA,128 patients with other rheumatic diseases and 90 healthy controls were involved.Enzyme linked immunosorbent assay ( ELISA) was used to detect anti-MCV and anti-CCP, and dynamic immune nephelometry was applied to detect RF-IgM .The sensitivity and specificity were obtained from the experimental data.Results:The sensitivities of anti-MCV,anti-CCP and RF-IgM were 85.1%,76.7% and 82.7%in RA respectively.The specificities were 93.2%,95.1%and 80.1%respectively.Combined detection of anti-MCV and anti-CCP,the sensitivity decreased to 70.2%; but the specificity increased to 98.7%.The sensitivity reached to 89.5% with specificity 97.6%when the union of anti-MCV and anti-CCP positivity was used as criterion.Conclusion:Anti-MCV and anti-CCP are novel makers for RA diagnosis with high sensitivity and high specificity.Combination of anti-MCV and anti-CCP is more helpful for RA diagnosis.

Objective To investigate the level of self-concept on occupation among junior nurses.Methods One hundred and thirty-nine nurses with nursing experience of 1-5 years were involved in the survey by using the Nurses' Self-Concept Questionnaire (NSCQ).Comparisons were done between the groups of nurses with undergraduate education and those with three-year training courses in terms of self-concept and its dimensions.Results The total score of junior nurses on self concept was(5.33±0.77).The score of the nurses with undergraduate education was(5.16±0.88),significantly lower than the score of(5.44±0.71)of the nurses with three-year training courses(P<0.05).Conclusion The nursing administration should attach importance to the self-concept on occupation, instructing specially the nurses with undergraduate education so as to enhance their mental health and their self-identification of nursing as an occupation.
