Objective:To study the expression levels of tumor-associated glycoprotein (TAG72) and glucose-regulated protein 94 (GRP94) in the breast benign and malignant lesions and detect their clinicopathological significance. Methods:EnVisionTM immunohistochemistry was used for assaying expressive levels of TAG72 and GRP94 in conventional paraffin-embedded sections from specimens of breast cancer (n=60) and benign lesions (n=30). The survival analysis was performed by using Kaplan-Meier method.Results:The positive rates and scores of TAG72 and GRP94 were significantly higher in breast cancer than those in benign lesions (TAG72: 68.3% vs 10.0%, 2.53±1.86 vs 0.37±1.13; GRP94: 63.3% vs 13.3%, 2.73±2.23 vs 0.47±1.22; P=0.000). The positive rates and scores of TAG72 and GRP94 were significantly lower in the intra-ductal,histological grade Ⅰ or Ⅱ , with maximal diameter ≤3 cm, without lymph node metastasis, estrogen receptor (ER)-positive, p53 and CA15-3-negative breast cancer than those in the ductal invasive (P<0.05), histological grade Ⅲ (P<0.01), maximal diameter >3 cm (P<0.05), with lymph node metastasis (P<0.01), ER-negative (P<0.05) , p53-positive (P<0.01), and CA15-3-positive (P<0.01) breast cancer tissues. Kaplan-Meier survival analysis showed that the median survival time were significantly shorter in the TAG72-positive, GRP94-positive or TAG72 and GRP94-positive breast cancer patients than those with negative TAG72 and/or GRP94 expression (P<0.01). Multivariate COX regression analysis showed that TAG72 and/or GRP94-positive expression were negatively associated with postoperative survival rate and positively related with death rate. Both of them were independent prognostic factors for breast cancer. Conclusion:The expressive levels of TAG72 and/or GRP94 might have important effects on the carcinogenesis, progression, biologic behaviors and prognosis of breast cancer. The breast cancer patients with over-expression of TAG72 and/or GRP94 might have poor prognosis.

Objective To evaluate the methods of diagnosis and treatment of thyroid disease with concomitant focal lymphocytic thyroiditis(FLT), and explore the reasons for its confused with Hashimoto′s disease(HD).Methods During the recent 25 years, 207 patients underwent surgical trearment for pathologically diagnosed HD.Among this group, 143 cases of HD with other concomitant thyroid disease were retrospectively analysed.Results Of the 143 cases, 57 cases were found to have thyroid disease with concomitant FLT, and this was 27.5%(57/207) of the total HD group, or 39.9%(57/143) of the group with thyroid disease and concomitant HD.Intraoperative pathologic section revealed that focal lymphocytic infiltration was positive in 87.7%(50/57) of cases. The postoperative hypothyroidism occurrence rate was 19.3%(11/57), of which, 7 cases(7/57, 12.3%) were subclinical hypothyroidism.Conclusions The character of pathologic changes of thyroid disease with FLT and with HD was different. Intraoperative pathologic section can be helpful in the diagnosis of this condition and can have important significance as a guide to the scope of (surgical) resection of the thyroid gland.

OBJECTIVE: To explore a research path and statistical analytical method for cost-utility analysis suitable for gallstone surgery patients.METHODS: A decision-making model for the treatment of cholelithiasis surgery was established;the costs(C) and utility values at each nodal point(? U) were collected,with the results subjected to sensitivity analysis and threshold analysis.RESULTS: The cost-utility ratios(CUR) of laparoscopic operation and open surgery were 4 605.6(? 30%) yuan/QALY and 5 979.7(? 30%) yuan/QALY,respectively.One dimension sensitivity analysis of each( every) parameter reveals that the former CUR value is greater than the latter one.C1 and ? U1 showed the biggest impact on the CUR of laparoscopic operation,while C5 and ? U5 did on the CUR of open surgery.When C1=10 205.6 yuan,or ? U1=1.303 or C5=10 979.8 yuan or ? U5=3.095,CUR of laparoscopic operation was equal to CUR of open surgery,which means that the conversion of threshold was achieved.CONCLUSION: The designed research path and statistic analytic methods are suitable for the cost-utility analysis of cholelithiasis surgery patients.

OBJECTIVE: To detect the expression of galectin-3 (gal-3) and Sambucus nigra agglutinin (SNA) and determine their clinicopathological significance in breast cancers and benign breast lesions. METHODS: Envison immunohistochemistry for staining gal-3 expression, and ABC affinity-cytochemistry to detect SNA expression were used in paraffin-embedded slides from specimens of breast cancers (n=60) and benign lesions (n=30). RESULTS: The positive rates and scoring means of gal-3 and SNA were significantly higher in breast cancer (48.3%, 2.07 +/- 2.25, 2.12 +/- 2.26) than those in benign lesions (26.7%, 1.03 +/- 1.63, 1.07 +/- 1.59, P < 0.05). The scoring means of gal-3 and SNA expression were significantly lower in the positive cases of estrogen receptor (ER) and the negative ones of CA15-3 than those in the negative cases and the positive ones (P < 0.05).The survival analysis of Kaplan-Meier showed the 5-year survival rate and mean survival period were significantly lower in the gal-3 or SNA expression positive cases than those in the negative cases of breast cancer (P<0.01). CONCLUSION The expressive level of gal-3 and SNA lectins might have important effect on the carcinogenesis, progression and biologic behaviors of breast cancer. The positive cases of gal-3 and /or SNA expression might have poor prognosis.

OBJECTIVE: To examine the psychometric features of the body image after breast cancer questionnaire-Chinese version (BIBCQ-C) in Chinese women with breast cancer. METHODS: A total of 545 women with breast cancer received a demographics investigation: BIBCQ-C and hospital anxiety and depression scale (HAD). Four weeks later, 31 patients were selected randomly to finish BIBCQ-C again. RESULTS: The Cronbach's alpha coefficient for the total scale was 0.90, and that for the 6 factors ranged from 0.62 to 0.87. The mean inter-item correlation coefficient of the total scale was 0.16, and the mean inter-item correlation coefficient of the subscales ranged from 0.21 to 0.57, and the test-retest reliability of the total scale and 6 factors was over 0.60. The confirmatory factor analyses supported the 6-factor model, and BIBCQ-C were significantly correlated with the symptom scales of anxiety and depression (r=0.20, 0.21, P<0.01). CONCLUSION BIBCQ-C is reliable and valid, which can effectively assess body image of Chinese women with breast cancer.
