Objective To evaluate the reliability and sensitivity of detection of thyroid carcinoma lymph node micrometastasis with MUC1.Methods In 488 cases of thyroid disease,1% methylene blue 1.0-2.0mL was injected into the thyroid nodule or surrounding thyroid tissue 24hours before operation.The dye-stained lymph nodes were detected at operation and RT-PCR method was used to determine MCUI in the clinically blue-stained lymph nodes.Results The detection rate of the blue-stained lymph nodes in thyroid carcinoma was 93%,and in benign lesions was 0%.In the research group,80 cases were found to have blue-stained lymph nodes,the detection rate was 95% and was higher than the pathologr diagnostic rate which was 86%(P

Objective To prove the application of bilingual teaching in the child health care curriculum. MethodsEnglish dubbing and Chinese subtitling DVD coursewares of child growth and development were played to medical interns.The interns were asked to do questionnaires to examine feasibility and effectiveness. Results In 8-year program medical students,77.8% of them and 64.8% of the 5-year nutrition professional students could understand the contents of more than 90%.If there was no Chinese subtitles,the ratio were only 5.6% and 6.4%.Most students preferred English subtitles and dubbing,and endorsed the model of bilingual teaching. Conclusion DVD coursewares with Chinese subtitles and English dubbing can be widely used in the teaching of child health care.

Objective To explore lymphocyte differentially expressed protein profile and its pathogenic significance in Huaihua Dong peoples with hypertension.Methods The lymphocyte protein profiles among 130 cases of blood specimen were detected and identified with matrix-assisted laser desorption ionization/time of flight mass spectrometry (MALDI-TOF-MS) and Mascot search against protein database.Results The reproducible protein-maps of two-dimensional gel electrophoresis were obtained among three groups.Compared with Dong normal peoples,the protein disulfide isomerase-related protein 5 and heat shock protein 27 showed higher expressions in the Dong peoples with hypertension (P ＜ 0.01),but chain A,structure of haemoglobin in the deoxy quaternary state with ligand bound at the alpha haems is no statistical significance(P ＞0.05).Those three proteins were upregulated in Han peoples with hypertension (P ＜0.01).Conclusions The up-regulation of the protein disulfide isomerase-related protein 5 and heat shock protein 27 in the Dong and Han peoples with hypertension suggest that those two proteins might be associated with the occurrence and development of hypertension.

Objective To investigate the association of single nucleotide polymorphisms(SNP)in p21and p27 genes with the risk of epithelial ovarian cancer(EOC).Methods Genotypes were analyzed by polymerase chain reaction-restrictive fragment length polymorphism(PCR-RFLP)method in 234 patients with EOC and 284 control women in China.Results (1)The frequencies of the p21 in healthy controls were 34.2%.49.6%and 16.2%,while the distribution of the C and T allele was 59.0%and 41.0%,respectively.The p21 C/C(28.2%),C/T(53.0%),T/T(18.8%)distribution in ovarian cancer patients was not significantly different from that in healthy controls(P＞0.05).There was no statistic difference in allele distribution between ovarian cancer patients and healthy controls(P＞0.05)either.The stratification analysis by tumor histological type did show that the genotype distribution in four types of ovarian cancer patients was significantly different from that in healthy controls(P=0.02).The C/C genotype was likely to reduce the risk of epithelial endometrial cancer.and the adjusted odds ratio was 0.56(95%CI:0.32-0.98).(2)The genotype frequencies of the p27 in healthy controls were 88.4%,10.9%and 0.7%.while the distribution of the V and G allele was 93.8%and 6.2%.respectively.The V/V(93.6%),V/G(5.1%)and G/G(1.3%)distribution in ovarian cancer patients was significantly different from that in healthy controls(P=0.04).There was no statistic difference in allele distributionbetween ovarian cancer patients and healthy controls(P＞0.05).Compared with the V/G and G/G genotypes,the V/V genotype increased the risk of EOC,the adjusted odds ratio was 1.92(95%CI:1.02-3.63).Conclusion The C/C genotype of p21 may reduce the risk of epithelial endometrial cancer,and the genotype of p27 V/V may be a potential risk factor for susceptibility to EOC.

Background The alteration of dominance eye is associated with visual quality in patients with age-related cataract or after cataract-surgery.However,the study on the relationship of dominance eye shift with vision following cataract-surgery is lack.Objective This study was to observe the influence of age-related cataract and cataract surgery on ocular dominance in the elderly.Methods A serial cases-observational study was designed.Eighty-seven patients with age-related cataract were collected from December 2011 to April 2012 in Affiliated Eye Hospital of Wenzhou Medical University,and phacoemulsification combined with intraocular lens (IOL) implantation was performed in all the patients.The patients were grouped into binocular vision difference (best corrected distance vision) ≥2 lines group (42 patients) and ≤ 1 line group (45 patients) on the standard logarithmic visual acuity chart.The frequency and shift of dominant eye were determined by card-hole method or thumb method before operation and 1 day,1 week,1 month and 3 months after operation.The difference in the frequencies of dominant eye between before and after operation was analyzed with MecNmar test.Results The median of best corrected distance vision (LogMAR) was 0.40 (0.00-1.40) in preoperation and 0.00 (-0.08-0.30) in postoperation,with significant difference between them (Z=-9.481,P =0.000).In the binocular vision difference ≥ 2 lines group,the dominant eyes were 24 in the right eyes and 18 in the left eyes.The milder cataractous eyes were identified as dominant eyes in 33 (78.57％) patients and heavier cataractous eyes were determined as dominant eyes in 9 (21.43％) patients before operation.However,the right eye was evidenced as dominant eye in 31 patients and the left eye was in 11 patients after operation.In the 42 patients,dominant eye shifted from the left eyes to the right eyes in 10 patients and from the right eyes to the left eyes in 3 patients,and 4 patients presented an unstable change binocularly.In 45 patients of the binocular vision difference ≤ 1 line group,the dominant eyes were the right eyes in 27 patients and the left eyes in 18 eyes in preoperation ; while after operation,dominant eye altered form the left eyes to the right eyes in 3 patients and form the right eyes to the left eyes in 1 patient,and unstable change occurred in 5 patients.There were no significant differences in the frequency of dominant eyes between before and after operation both the two groups (group A:P =0.092 ; group B:P =0.727).Conclusions Age-related cataract impact on eye dominance.Dominance eye may occur alteration binocularly following cataract surgery,which is one of causes of visual discomfort.
