Objective To explore Angptl2(angiopoietin-like protein 2)expression in tumor tis-sue and serum in patients with breast cancer(BC). Methods A total of 78 BC patients were enrolled in this study. Immunohistochemistry was used to detect Angptl2 expression in tumor and adjacent normal tis-sues. Preoperative and postoperative serum Angptl2 levels were determined via ELISA. Correlation among Angptl2 expression,clinicopathological factors and progression-free survival(PFS)were further evalua-ted. The receiver operating characteristics(ROC)curve was constructed to describe diagnostic specificity and sensitivity. Results Angptl2 was positively expressed in 64(82. 1% )cases. The rates of high and moderate expression of Angpt l2 in tumor and adjacent tissues were 53. 8%(42 / 78)and 7. 7%(6 / 78), respectively(P ﹤ 0. 001). Moreover,the elevated Angptl2 protein was significantly associated with lymph metastasis and adverse PFS. In addition,serum Angptl2 level in BC patients was significantly higher than that in benign controls[(218. 72 ± 88. 02)vs(80. 88 ± 30. 59)ng/ ml,P ﹤ 0. 01]. The area under the curve(AUC)was 0. 909,which indicated a good function for diagnosis. Postoperative serum Angptl2 level was decreased to(142. 43 ± 60. 29)ng/ ml,but still higher than that in controls(P ﹤ 0. 01). Conclusion The expression of Angptl2 may increase in tumor tissue and serum of BC and it may be a potential tumor marker for diagnosis and prognosis.

ObjectiveObserve the efficacy, toxicity and the effection of telomerase activity of allicin combined with paclitaxel plus cisplatin and 5-Fu(TFP)chemotherapy for patients with advanced gastric carcinoma.MethodsFifty-four patients with advanced gastric carcinoma were randomly divided into two groups. A group was treated with allicin and TFP, B group was only treated with TFP. The chemotherapy was paclitaxel (135 mg/m2, dl, 8) plus cisplatin (75 mg/m2, d2-4) followed by 5-Fu (500 mg/m2 d1-5). Allicin was used in 60 days(3 times every day,once 20 mg).Telomerase activity was performed by enzyme-linked immunosorbent assay. ResultsThe total efficiency rate was 40.7 ％ (11/27) in A group and 33.3 ％ (9/27) in B group.There was no statistical difference between the two groups(~ = 0.079,P =0.779).There was significant difference in nausea and vomit (P =0.043), and the incidence of A group was 77.8 ％ (21/27) which was lower than that of B group[92.6 ％(25/27)].There was statistical difference in telomerase activity between the two groups(P =0.000).ConclusionAllicin could reduce the toxicity of chemotherapy and inhibit the telomerase activity in advanced gastric carcinoma.

ObjectiveTo evaluate the influence of laparoscopic operation on pH value, phagocytic function of neutrophil, immunoadhesion activity of RBC CR 1 (complement receptor typeⅠ) in abdominal cavity. Methods Determination of the pH value, phagocytic function of neutrophil, immunoadhesion of RBC CR 1 in abdominal exudatives during laparoscopic procedures was undertaken and results were compared with the relative indexes detected in peripheral vein blood. Results The average pH value was 7.41, the percentage of the phagocyte was 74.6%, phagocytic index 55.7, and immunoadhesion activity of RBC CR 1 was 58% in blood during laparoscopic operation. While the average pH value was 7.14, the percentage of the phagocyte 65.6%, phagocytic index 47.6,and immunoadhesion activity of RBC CR 1 50% in the abdominal exudatives. Conclusion Compared with the peripheral vein blood indexes, the intraabdominal pH value, phagocytic function of neutrophil and immunoadhesion activity of RBC CR 1 decreased significantly during laparoscopic operation. The intraabdominal inflammation may diffuse with the effect of CO 2 pneumoperitoneum when patients with serious inflammation receive laparoscopic operation.

Objective: To evaluate the clinical value of 18F-FDG PET/CT in diagnosing the recurrence or metastasis of the postoperative patients with gastrointestinal malignant tumor. Methods: Sixty-eight postoperative patients with gastrointestinal malignant tumor were studied with 18F-FDG PET/CT, and serum CEA and CA19-9 were assayed. Results: Thirty-seven patients were found to be recurrent or metastatic. The sensitivity and specificity of PET/CT detection were 97.3% and 96.8%,and the positive rates of PET/CT combined with CEA and CA19-9 were 100% and 97.8%.Conclusion: PET/CT has a higher sensitivity and specificity than tumor marker detection in assessment of recurrence and metastasis.

Objective To assess the outcome of fixation of Rüedi-Allg(o)wer type Ⅱ and Ⅲ pilon fracture using multiple low-profile plates (MLPP) via multiple incisions.Methods A retrospective study was made on 21 cases of pilon fracture immobilized using MLPP via multiple incisions between July 2007 and March 2012.There were 7 cases of Rüedi-Allgower type Ⅱ and 14 type Ⅲ.Fractures were reduced and fixed based on X-ray films and CT scans for fracture line and effect area.Quality of reduction was evaluated by Burwell-Charnley radiological score.Ankle and hindfoot functions were evaluated by American Orthopedic Foot & Ankle Society ankle-hindfoot scale.Fracture types,healing rate,and wound complication incidence were recorded.Results All fractures were healed,with the excellence rate of 95％ (20/21).According to AOFAS score,the results were rated as excellent in 11 cases,good in 6,fair in 4,with the excellence rate of 81％.None suffered from wound infection,except for wound dehiscence in 1 case and traumatic arthritis in 5.Conclusion Treatment of pilon fractures by MLPP via multiple incisions can reduce wound complications,promote reduction and stabilization of fracture,and satisfy the demand of early movement and late weight bearing of the ankle.

OBJECTIVETo investigate the different expressions of ER and ER gene status between primary and relapsed/metastatic lesions and their clinical significance.

METHODSER and ER gene status of primary and relapse/metastatic breast cancer masked in 70 metastatic breast cancer patients were assessed by determination of methylation status by immunohistochemistry (IHC) and methylation specific polymerase chain reaction (MSP), respectively.

RESULTSPositive rate of ER in the primary breast cancers was 64.3%, and in the relapse/metastatic lesions was 41.4% (P < 0.05). There were six patients whose positive ER status was changed to negative, among them the ER gene status was changed from demethylation to hypermethylation in four cases. Another four patients with negative ER status changed to positive, and their ER gene hypermethylation changed to ER demethylation status.

CONCLUSIONSThe discordance of ER expression status in primary and relapse/metastatic lesions of breast cancer might be related to DNA methylation status.
