Chinese Journal of Geriatrics 2010;29(7):563-565
Objective To study the advantage and disadvantage of different treatments of unstable distal radial fractures in elderly patients. Methods In the period from August 2005 to January 2010, 55 elderly patients with unstable d istal radial fractures were treated with manual diaplasis and external plaster splint fixation, operation and internal plate fixation, or external fixation. Clinical outcomes were evaluated by Gartland-Werley wrist scoring systems and questionnaire of the disabilities of the Arm, Shoulder and Hand (DASH). We used SPSS13.0 software package for statistical analysis. Results Compared with the manual diaplasis group, the operation and internal plate fixation group or external fixation group was better in Gartland-Werley scores, the differences were statistically significant (P<0.05), but there were no differences in DASH scores among the 3 groups. Conclusions The treatment of unstable distal radial fractures in elderly patients should be chosen based on the characteristics of the fractare and patients desire.
2. Expression of ER, PR, HER-2, PCNA and P53 genes in breast cancer patients in Shanghai and the relevant clinical significance
Academic Journal of Second Military Medical University 2010;31(7):748-752
Objective: To investigate the expression of ER, PR, HER-2, PCNA and P53 in breast cancer patients in Shanghai and the relevant clinical significance. Methods: Expressions of ER, PR, HER-2, PCNA and P53 in the breast cancer tissues of 544 patients in Shanghai were detected by immunohistochemistry methods. Statistical analysis was applied to analyze the relationship of these immunohistochemical indices with the clinicopathological features of breast cancer. Results: The positive rates of ER, PR, HER-2, PCNA and P53 in the breast cancer tissues of 544 patients were 62.2%, 57.2%, 15.1%, 82.6% and 58.5%, respectively. The expressions of ER, PCNA and P53 were correlated with the tumor size (P<0.05, P<0.01). The expressions of HER-2 and PCNA were correlated with axillary lymphatic metastasis (P<0.05, P<0.01). ER expression was positively correlated with PR expression(r=0.452, P=0.000) and PR expression was positively correlated with P53 expression (r=0.520, P=0.03). The 123 (22.6%) patients with triple-negative breast cancer (TNBC) had a higher axillary lymphatic positive rate than patients with non-TNBC (P<0.01). Co-expression of HER-2 with PCNA and co-expression of HER-2 with P53 were positively correlated with lymphatic metastasis (P<0.05). Conclusion: Population aging has a influence on the immunohistochemical characteristics of breast cancer patients patients in Shanghai. Combined examination of ER, PR, HER-2, PCNA and P53 is of clinical significance in the diagnosis, treatment, and prognosis prediction of breast cancer patients.

Objective To detect and analyze the levels of preoperative serum carcino-embryonic antigen (CEA) and CA15-3 in early invasive breast cancer patients and their correlation with pathological parameters. Methods Electrochemical luminescence immunoassay (ECLI) technology was used to detect serum levels of CEA and CA15-3 in 223 cases of early invasive breast cancer patients, 109 patients with benign lesions, and 30 cases of heath control. Immunohistochemical (IHC) and fluorescence in situ hybridization (FISH) were used to detect the estrogen receptors (ER), progesterone recepter (PR), and its HER-2 pathological indicators.Besides, the correlation of serum CA15-3, CEA levels and pathological parameters was analyzed. Results The serum CA15-3 and CEA levels of Breast cancer patients [(22.27±15.11) U/ml, (5.03± 0.49) μg/L] were significantly higher than that of patients in benign lesion group [(14.13±3.04) U/ml, (2.72± 0.11) μg/L] (P< 0.05). CEA level of patients with histological grade Ⅲ was (6.34 ±0.93) μg/L, significantly higher than the level Ⅰ-Ⅱ (4.23±0.50) μg/L (P< 0.05). CA15-3 level was (19.26±15.08) U/ml in T1 tumors, and CA15-3 level was (28.73 ±11.53) U/ml in T2 tumors (P<0.05). The serum levels of CEA and CA15-3 between different histology, pathologic stage, lymph node status, ER, PR, HER-2, pathological characteristics had no significant difference (P>0.05). CEA positive rate of breast cancer group was significantly higher than that of benign lesions(13.5%vs. 3.7%, 26.5%vs. 1.8%, P<0.05). 30 cases of normal control group had no positive one. The joint monitoring sensitivity of CEA and CA15-3 breast cancer group was 9.4 %, the sensitivity was 0 in benign lesion group. There was significant difference (P < 0.05). Conclusion The changes of Serum CA15-3 and CEA levels in breast cancer patients can be considered as the judgment standard for early diagnosis, pathological staging, prognosis and clinical effect monitoring.
