Objective:
To observe the effects of axial vascular network flap of scalp or anterolateral thigh perforator flap with fascia lata on repairing defects after radical resection of scalp carcinoma in patients.
Methods:
From February 2006 to December 2015, twenty-one patients with scalp carcinoma were admitted to our hospital, and the carcinoma invaded external lamina or full-thickness of skull and dura mater. After perfect preoperative examination, carcinoma and scalp tissue in 3 to 5 cm from the edge of carcinoma, external lamina or full-thickness of skull and invaded dura mater were resected and sentinel lymph nodes around carcinoma were cleaned in 3 to 4 days after admission. The postoperative defects with size reached from 11 cm×8 cm to 22 cm×18 cm. The flap transplantation was performed at the same time when quick frozen pathological examination results of resected scalp carcinoma margin tissue, skull, dura mater margin and basal tissue, and sentinel lymph nodes showed completely negative. Defects in 3 elderly patients were repaired by single or multiple axial scalp vascular network flaps, with the resected flaps size ranged from 12 cm×7 cm to 19 cm×14 cm. Defects in the other 18 patients were repaired by anterolateral thigh perforator flaps with fascia lata, with the resected flaps size ranged from 13 cm×10 cm to 23 cm×19 cm and the resected fascia lata size ranged from 8 cm×7 cm to 10 cm×10 cm. The head donor site of flap was repaired by medium thickness skin of head and back; the thigh donor site of flap was repaired by medium thickness skin of thigh on the same side. All patients gave up postoperative radiotherapy, chemotherapy, and other follow-up treatments.
Results:
After operation, the flap and skin in all patients survived completely, with no vascular crisis or other condition. During the follow-up for 6 months to 9 years, all patients showed good appearance except for baldness in operation area of head, with no obvious malformation in head donor site of flap and skin, no swollen external hernia in the brain tissue, and no local recurrence or distant metastasis of carcinoma. The appearance of thigh donor site of flap and skin was good, with normal muscle strength and movement of lower limbs.
Conclusions
Patients with scalp carcinoma were performed with radical resection of carcinoma, and axial vascular network flap of scalp or anterolateral thigh perforator flap with fascia lata were applied to repair the postoperative defects, with good appearance of head operation area and no local recurrence or distant metastasis of carcinoma.

RESULT:
The positive expression rate of SDF-1 and CXCR4 in laryngocarcinoma was obviously higher than in paraneoplastic tissues and normal laryngeal mucosa tissues (P < 0.01). And the expression of two proteins was correlated with lymph node metastasis (P < 0.01), clinical stage (P < 0.01) and pathological grading of tumor (P < 0.05). The positive expression rate of SDF-1 and CXCR4 protein in metastasis lymph node tissue was higher than that in non metastasis lymph node tissue (P < 0.01). The expression of SDF-1 is correlated positively with the expression of CXCR4 in laryngocarcinoma.
CONCLUSION
SDF-1 and CXCR4 protein are highly expressed in laryngocarcinoma and in metastasis lymph node tissue. And they are correlated with lymph node metastasis, clinical stage and pathological grading of the tumor. According to the results, the two proteins may relate to infiltration and metastasis of laryngeal squamous cell carcinoma and play a role of synergistic action in the development and invasion of carcinoma of larynx.

Objective: To screen related genes of melanoma-associated antigen-A11 (MAGE-A11) in breast cancer cells based on highthroughput DNAmicroarray technology, and to validate from the aspects of quantity and function. Methods: DNAmicroarray was used to screen the differently-expresseddown-stream mRNAs of MAGE-A11 in breast cancercelllines (MCF-7, MDA-MB-231 and BT-549). Cluster analysis was applied on representative genes and quantitative RT-PCR was used to validate. CCK-8, scratch wound healing assay and Transwell assaywere used to detect the effect of MAGE-A11 on the proliferation,migration and invasion of breast cancer cells. Results: Over-expression of MAGE-A11 caused the differential expression of 1608 down-stream genes in 3 breast cancer cell lines, which was associated with various cell functions such as protein ubiquitination,cell proliferation and apoptosis, tumor invasion and metastasis.qRT-PCR validated that the expression of ZNF-451, CENPTJ, CDK13, API5 and LMO7, which were highly expressed in microarray, were also significantly higher than those in control group (P<0.01);in addition, SHPRH, PML, MARK2, LIMA1 and ANGPTL4, which were low-expressed in microarray, were also significantly lower than those in control group (P<0.01). MAGE-A11transfection directly increased the proliferation of breast cancer MCF-7, MDA-MB-231 and BT-549 cells at 72 h (all P<0.01); compared with control group after transfectionexhibited obvious wound healing at 48 h (P<0.05 or P<0.01) and significantly increased trans-membrane cell numbers (all P<0.01). Conclusion: Many differentially expressed genes related to ubiquitination, cell proliferation and apoptosis, tumor invasion and migration were screened in MCF-7, MDA-MB-231 and BT-549 breast cancer cells. Among them, 10 typical differentially expressed genes were identified in terms of quantity and function.

Objective: To detect the expression of miR-133a-3p in gastric cancer (GC) tissues and plasma of GC patients, and to investigate its effect on the proliferation of GC cells as well as its correlation toprognosis of GC patients. Methods: 52 cases of cancertissues (non-necrosis part) and corresponding adjacent tissues as well as the pre-operative peripheral blood samples from GC patients, who underwent surgery at Department of General Surgery, the Forth Hospital of Hebei Medical University(Shijiazhuang, China) between May 2012 and May 2013, were collected for this study. The plasma sample (n=35) from healthy donors were obtained during their physical examination. RT-qPCR was adopted to detect the expression of miR-133a-3p in gastric cancer tissues, adjacent tissuesand plasma samples of GC patients and healthy volunteers. The relationships between miR-133a-3p expression and the median DFS as well as clinicopathological parameters were also analyzed. CCK-8 assay was adopted to detect the effect of miR-133a-3p silence or over-expression on proliferation of gastric cancer SGC7901 cells. Results: miR-133a-3p was dramatically decreased in gastric cancer tissues (P<0.01), and its expression was associated with TNM stage, tumor infiltration (T), lynphonode metastasis (N), and vascular tumor thrombus (all P<0.01); miR-133a-3p was significantly increased in the plasma of GC patients (P<0.01), and its expression was associated with TNM stage, lynphonode metastasis (N), and vascular tumor thrombus (all P<0.05). miR-133a-3p expression was positively correlated with serum CA199 level of GC patients (P<0.01). The median DFS of patients with high miR-133a-3pexpression in cancer tissues was significantly longer than that of the patients with low expression(20.8 vs 14.8 months, P<0.05); The median DFS of patients with high plasma miR-133a-3p expression was significantly shorter than that of the patients with low expression (14.4 vs 20.3 months, P<0.05). Over-expression of miR-133a-3p could significantly inhibit the proliferation of gastric cancer SGC7901 cells, while miR-133a-3p silence could significantly promote the proliferation (all P<0.05). Conclusion: miR-133a-3p could significantlyinhibit the proliferation of SGC7901 cells; miR-133a-3p aberrantlyexpressed in gastric cancer tissues and plasma, and obviously correlated with prognosis of gastric cancer patients, which may be used as a potential clinical bio-maker for early diagnosis and treatment as well as the prognosis prediction of gastric cancer.

Objective: To evaluate the expression of melanoma antigen A family(MAGE-As)in the peripheral blood of patients with esophageal carcinoma (EC), and to analyze its correlations to the clinicopathological features and the prognosis of EC patients. Methods: mRNA expression of MAGE-As in peripheral blood from 153 EC patients and 30 healthy donors was detected using multiplex semi-nested PCR. In addition, restriction endonuclease treatment was used to determine the expression of MAGE-As family members, including MAGE-A1, A2, A3, A4 and A6. Results: The positive expression of MAGE-As was observed in 30 of 153 EC patients (19.61%) in peripheral blood. The positive expression rate of MAGE-A1, A2, A3, A4, A6 was 10.46% (16/153), 16.34%(25/153), 9.8% (15/153), 11.11% (17/153) and 18.30%(28/153), respectively. Additionally, the expression of MAGE-As was positively associated with clinical stage, lymphatic metastasis and distant metastasis (all P<0.05). The positive expressions of MAGE-As and its sub-type genes were all associated with low 5-year overall survival of ES patients (all P<0.05). Expression of MAGE-As, tumor volume, lymphatic metastasis and distant metastasis can be used as independent prognostic factors for the survival of EC patients (all P<0.01). Conclusion: The expression of MAGE-As in peripheral blood of EC patients was associated with the prognosis of EC, and may be used as an important indicator for the prognosis of esophageal carcinoma.

[Abstract] Objective: To observe the effect of allogeneic platelets transfusion on the invasion and metastasis of human lung cancer A549 cells, and to preliminarily explore its mechanism of action. Methods: Eighty-nine patients with advanced lung cancer, who had received platelet transfusion in the Chemotherapy Department of Fourth Hospital of Hebei Medical University between January 2017
and December 2018, were enrolled in this study. The study cells were randomized into Ctrl group (A549 cells co-incubated with culture medium), Before group, and After group (A549 cells co-incubated with plasma Before and After platelet transfusion, respectively). The migration and invasion of A549 cells co-cultured with plasma before and after platelet transfection were detected by Scratch and
Transwell experiments. The expression of MMPs, TIMPs and epithelial-mesenchymal transition (EMT) related proteins E-cadherin, N-cadherin and Vimentin, as well as vascular endothelial growth factor (VEGF) and its receptor 2 (VEGFR2) were detected by Western blotting (WB) method. Results: The scratch healing ability of A549 cells in After group was significantly higher than that of Ctrl group
and Before group [(73.67±2.60)% vs (58.33±2.33)%, (35.33±2.03) %; P<0.01, vs Ctrl group; P<0.05, vs Before group], and there was also a significant difference between Before group and Ctrl group (P<0.05). The results of cell migration experiment showed that the number of transmembrane cells in After group was significantly higher than that in Ctrl group and Before group [(69.67±7.84) vs (18±2.08) and (39.33±2.03), all P<0.01]. The cell invasion experiment showed that the number of transmembrane cells in After group was significantly higher than that in Ctrl group and Before group [(59.34±3.46) vs (18.34±1.56) and (37.58±2.79), all P<0.01]. When A549 cells were co-incubated with plasma before and after platelet transfusion for 48 h, it was found that the expressions of MMP9 and MMP2 were increased (P<0.05), while their inhibitors TIMP1 and TIMP2 were decreased (P<0.01); the expressions of EMT-related proteins N-cadherin and Vimentin were increased (P<0.05), but E-cadherin was decreased (P<0.01); the expressions of angiogenesis related proteins VEGF and VEGFR2 were increased (P<0.05). Conclusion: Alloplatelets transfusion can promote the invasion and metastasis of lung cancer A549 cells, which may be realized by regulation of the expressions of EMT, metallomatrix protease and vascular growth factor-related proteins.
