Objective:To investigate the expression and correlation of EHD2 and E-cadherin in hepatocellular carcinoma (HCC). Meth-ods:Western blot and immunohistochemistry were used to detect the expression of EHD2 and E-cadherin in HCC specimens and adja-cent noncancerous tissues. The correlations of EHD2 and E-cadherin with the clinicopathological characteristics and prognosis of pa-tients were further analyzed using Pearsonχ2 test and Kaplan-Meier method. Results:EHD2 expression, along with E-cadherin, was markedly reduced in HCC tissues than in adjacent noncancerous tissues. Moreover, EHD2 and E-cadherin expression were correlated with histological grade, microvascular invasion, and lymph node metastasis (P<0.05). Kaplan-Meier survival analysis showed that HCC patients with decreased EHD2 and E-cadherin expression had shorter overall survival time than those with higher expression. Conclu-sion:The abnormal expression of EHD2 and E-cadherin possibly promote HCC. Detection of EHD2 and E-cadherin may be valuable for diagnosing HCC and evaluating malignancy extent and prognosis.

Objective To assess the effectiveness of uterine arterial embolization for the treatment of hysteromyomas and to discuss the factors related to the clinical results.Methods Super-selective uterine arterial embolization was performed in forty-five patients with hysteromyomas.Of 45 patients,multiple hysteromyomas were seen in 36 and solitary lesion in 9.The lesion was located at the myometrium in 41 cases,among them coexisted endometrioma was found in 5 cases and coexisted submucosal myoma in 2.The lesion was located submucous layer in the remaining 4 cases.The diagnosis was confirmed by imaging study and gynecological examination.After the operation,ultrasonography and laboratory tests were carried out in all patients to observe the tumor size.hormone levels and hemoglobin concentration.Results A total of 91 uterine arteries were found in 45 patients.including double left uterine arteries in one case.Successful catheterization was obtained in 87 arteries(95.6%).All forty-five patients were followed up for 6-36 months.Six months after the procedure the mean reduction of the tumor size was 69.3%.and the lesion completely disappeared in two cases.In the anemic patients the hemoglobin concentration returned to normal level.The main side-effects included low fever and pain at lower abdomen.Conclusion Uterine arterial embolization is a safe and effective treatment for hysteromyomas.

Objective To explore the impact of calciotropic hormones,such as parathyroid hormone (PTH)and vitamin D,on bone mineral density(BMD)in the old men with type 2-Diabetes.Methods Sixty elderly men with type 2-Diabetes were submitted to dual-energy X-ray absorptiometry to evaluate the BMD at lumbar spine and hip.Fasting blood samples were collected to evaluate the indexes of bone metablism and blood glucose.PTH and 25-(OH)-Vitamin D3 were measured and analyzed for their correlation with BMD at different sites.Results In all patients,the percentage of osteoporosis and osteopenia accounted for 20.0％ and 53.3％ of the patients according to BMD at lumbar or hip.Compared with the patient group with normal BMD,serum PTH was significantly higher in the patient group with osteopenia or osteoporsis([44.87 ± 10.62]μg/L vs[36.96 ±12.36]μg/L,P ＜ 0.05 ;[50.24 ± 20.32]μg/L vs[36.96 ± 12.36]μg/L,P ＜ 0.05).But there was no difference in 25-(OH)-Vitamin D3 levels between all groups.PTH was correlated negatively with BMD at hip (r =-0.224,P ＜ 0.05),but not significantly correlated with BMD at lumbar(r =-0.187,P ＞ 0.05)Conclusions Serum PTH was correlated negatively with BMD at hip in elderly man with type 2-Diabetes.

Objective Linkage analysis were performed in 2 pure Chinese paroxysmal kinesigenic dyskinesia families to localize the locus of them. Method Microsatellites markers corresponding to pericentrometric region of chromosome 16 were used in parametric and nonparametrie linkage analysis for 27 members in the 2 pedigrees, haplotypes were constructed subsequently. Result The maximum LOD score and NPL score in the 2 families were all negative, P values were significantly larger than 0.05.No haplotype segregated with PKD phenotype was found. It showed no evidence of association with known PKD loci in both pedigrees, providing evidence for a novel PKD locus. Conclusion PKD is heterogeneous, a novel PKD locus may be in pure Chinese pedigrees.

Objective: Evaluating ovarian carcinoma diagnosis,staging and resectability with EBCT. Methods: 25 cases of ovarian carcinoma were performed in total abdominal including pelvic with EBCT one week before operation.CT findings were compared and analysed with surgical and pathological results. Results: Of 25 patients,11 were serous cyst adenocarcinoma,six mucinous cyst adenocarcinoma,three malignant teratoma,two metastases,and each have only one for clear cell carcinoma,embryo carcinoma and undifferentiated carcinoma.Clinical staging of carcinoma were seven in stageⅠ,seven in stage Ⅱ,nine in stage Ⅲ,two in stage Ⅳ.Invaded vessels and nearby organs around ovarian carcinoma,and the status of peritoneum metastases,were main factors that influenced the difficulties of operation.Compared with conventional CT,EBCT has the virtues of ultrafast scanning,excellent quality of image,and displaying focus detail fine.Conclusion: EBCT scanning is very valuable in diagnosis,tumor staging and evaluating resectability of ovarian carcinoma.

Objective To explore the possible risk factors that influence bone mineral density (BMD) in the elderly man with type-2 diabetes.Methods Sixty elderly man with type-2 diabetes were subjected to dual-energy X-ray absorptiometry to evaluate the BMD at lumbar spine ( LS),and femoral neck (FN).Fasting blood and urine samples were taken to check the biochemical levels about bone metablism and blood sugar.The correlations between BMD and other factors were analyzed.Results In this group of patients,the percentage of osteoporosis and osteoponia was 20％ and 53.3％ in LS or FN site,respectively.Age,Weight,and HbA1c were correlated with BMD.Weight of them had the best correlation with BMD at LS( r =0.254,P ＜0.01 ),whereas,HbA1c had the best correlation with BMD at FN( r =-0.224,P ＜0.01 ).Conclusions Age,Weight,and HbAlc c were correlated with BMD of elderly man with type-2 diabetes.

Objective To understand the present condition of preclinical dental undergraduate in-terns' AIDS-related knowledge. Methods The questionnaire was designed referring to domestic and foreign relevant questionnaires. The cluster sampling method was used to conduct the questionnaire survey among the undergraduates who started their clinical internship in July 2016 in three domestic colleges, using SPSS 14.0 statistical software to analyze it. Results In this survey, 144 questionnaires were distributed, and 144 ones were filled out and sent back. The survey results suggested that 97.22％ (140) of interns held a posi-tive attitude towards aiding HIV-infected patients despite that 96.53％ (139) of interns knew that dental medical staff was considered to be highly susceptible with HIV. In spite of the fact that most interns knew AIDS-related knowledge and protection measures, 40.28％ (58) of interns were not clear about incubation period of AIDS, and the average awareness of children's AIDS and methods to disinfect HIV-infected dental instruments was less than half in the interns. Meanwhile it was found that 86.81％ (125) of interns didn't perform well in terms of complying with the principles of confidentiality in AIDS prevention and treatment. Conclusion Dental clinical interns' attitudes towards AIDS-infected patients should be praised. Further-more, they should accept education about infection control to have a deeper understanding about AIDS-related clinical manifestations and legal knowledge in order to reduce the probability of nosocomial infec-tion of AIDS.

Objective:To understand the levels of Pb, Cd, As, Hg, Mn, and Se in maternal and umbilical cord blood, and to explore the transplacental transfer efficiency (TTE).Methods:From September 2010 to December 2013, a total of 773 pregnant women and their newborns (Laizhou Bay Birth Cohort) were recruited from a second grade hospital in the south bank of Laizhou Bay, Bohai, Shandong Province. According to different detection methods, the six measured elements are classified into three groups including the Hg measurement group (595 mother-newborn pairs), the Pb measurement group (534 mother-newborn pairs), and the Cd, As, Mn and Se measurement group (244 mother-newborn pairs). The demographic characteristics of pregnant women and their newborns were obtained by the questionnaire. The concentrations of elements in maternal and umbilical cord blood were detected and the TTE of each element (elemental concentration in cord blood/elemental concentration in maternal blood) was calculated. The correlation of elements between maternal and cord blood was analyzed using Spearman′s rank correlation coefficient.Results:The mean± SD of maternal age, gestational week and newborn birth weight of 773 mother-infant pairs were (28.34±4.50) years, (39.47±1.39) weeks and (3 419.47±497.39) g respectively. The median concentrations of Pb, Cd, As, Hg, Mn and As in maternal and cord blood were 31.12 and 30.02, 1.19 and 0.47, 8.05 and 6.03, 0.69 and 1.26, 100.70 and 105.55, 127.25 and 115.00 μg/L, respectively. The TTE of Pb, Cd, As, Hg, Mn, and Se was 0.98, 0.41, 0.73, 1.73, 0.96 and 0.91, respectively. Pb, Cd, Hg, Mn, and Se showed a significant positive correlation between maternal blood and cord blood, with Spearman correlation coefficients of 0.397, 0.298, 0.698, 0.555, and 0.285 (all P values<0.001). Conclusion:Each element was commonly detected in maternal blood and cord blood. The TTE of Hg was the highest.
