Objective To study the impact of postoperative aerobic exercise on the cardiac function of breast cancer patients during anthracyclines-based chemotherapy. Methods Sixty cases of female breast cancer pa-tients, from June 2014 to December 2015 for anthracyclines-based chemotherapy, were randomly divided into ex-perimental group (n = 30) and control group (n = 30). Four cycles of conventional anthracyclines-based chemotherapy were conducted in control group, while three times of aerobic exercise per week were added in exper-imental group until the end of treatment course apart from conventional treatment. The peak oxygen consumption (VO2max) and maximum heart rate (HRmax) were measured before and after chemotherapy in both groups, ac-companied by ECG monitoring and blood collecting to measure the changes in their N-terminal pro-brain natriuretic peptide (NT-proBNP), serum creatinine (SCr) and kinase isoenzyme (CK-MB). Results No significant differ-ences in various indicators before chemotherapy were reported between two groups (P>0.05). After chemotherapy, VO2 max/kg [(21.9 ± 3.6) vs. (14.5 ± 2.8) mL/(min·kg)], VO2 max [(1 523 ± 186) vs. (911 ± 185) mL/min] and HRmax[(115 ± 15) vs. (129 ± 16) beats/min] in experimental group were significantly improved when com-pared with those in control group; significant differences in hematological levels and ECG changes were also ob-served between two groups. Conclusion Aerobic exercise during chemotherapy can mitigate the cardiotoxicity of anthracyclines to patients, which provides a new idea and therapy to reduce the incidence of clinical cardiovascular events induced by anthracyclines-based chemotherapy.

Objective To evaluate application feasibility of Array CGH in genetic diagnosis of clinical complex chromosomal abnormalities.Methods Two patients of genetic counseling and two patients of prenatal diagnosis were selected from Xiamen Maternity & Child Health Care Hospital during the period of December 2010 to December 2011.Under aseptic conditions 2-4 ml peripheral blood was collected in EDTA and 2-3 ml Cord Blood was collected through cordocentesis after genetic counseling and preoperative examination.G-banded chromosome analysis and genome DNA extraction were carried out on the four cases.The whole genome of four cases were scanned and analyzed by Array CGH.The results of Array CGH were confirmed by FISH.Results Array CGH detected different kinds of duplications and deletions in several chromosomes.Most of these duplications and deletions were not detected by karyotype analysis.The results of Array CGH showed duplication of 4p16.3-4p15.31,deletion of 4p16.3 in the first case,duplication of Xp11.22-Xq11.1 in the second case,duplication of 4p16.3-4p15.32,deletion of 2q37.3 in the third case and duplication of 2q21.2-2q32.1,deletion of 2q14.3-2q21.1 in the fourth case.These duplications and deletions were confirmed by FISH.Conclusions Compared with conventional cytogenetic analysis,Array CGH can not only accurately detect micro deletion and micro duplication with high resolution and sensitivity but also identify breakpoints precisely.Array CGH can provide the basis for clinical genetic diagnosis.

OBJECTIVETo provide experimental proof for establishing a standard quality evaluation method of adhesive property on Cataplasma by studying the factors of effect on evaluation of adhesive quality on Cataplasma.

METHODWith 180 degrees peel off test, tensile shear and adhesive force test, the influence caused by the square of samples, texture of fabric base and the moisture loss was tested with multifunctional material tester and first stickiness tester.

RESULTThe peel off strength of 40 mm wide sample is 26% lower than that of the 20 mm wide sample (P < 0.05), and tensile shear strength had no significant difference. The peel off strength of transverse fabric base was higher than that of lengthways fabric base (P < 0.01). The tensile shear strength of transverse fabric base was lower than that of lengthways fabric base (P < 0.05). The sample with 35% moisture lost had a maximum tensile shear strength and the sample which lost 30% moisture lost had a maximum peel off strength; The sample which lost 20% moisture lost had a maximum first adhesive force.

CONCLUSIONThe square of samples, the texture of fabric base and the moisture loss of samples can all affect the evaluation of adhesive quality on Cataplasma.

OBJECTIVETo evaluate the value of (18)F-FDG PET-CT in detecting the primary tumor in patients with metastatic cancers of unknown primary origin.

METHODSSixty-seven patients with metastatic cancers of unknown primary origin after extensive conventional diagnostic work-up were enrolled into this study. (18)F-FDG PET-CT scans were performed at approximately 60 minutes after the intravenous injection of 7.4 MBq (18)F-FDG/kg, then delayed imaging scans was done at approximately 180 minutes for detecting the primary focus. The standardized uptake value (SUV) >or= 2.5 on standard PET/CT imaging was considered as positive. Ten percent increase of retention index (RI) was also regarded as positive. The correlation between (18)F-FDG PET-CT results and histopathological and clinical findings were analyzed, and the SUV of detected primary focus and that of metastatic cancers were compared.

RESULTSOf the 67 patients, the primary tumors were identified in 39 (53.7%) by (18)F-FDG PET-CT, and 36 of them were confirmed by pathology or follow-up. Thirteen distant metastases and seventeen lymphatic metastases were newly discovered by whole body (18)F-FDG PET-CT imaging. The SUV of metastatic tumors was significantly lower than that of primary tumors (t = 3.470,P = 0.001) and closely correlated with that of the primary tumors (r = 0.738, P = 0.000).

CONCLUSION(18)F-FDG PET-CT is not only valuable in identifying the unknown primary tumor in patients with metastatic carcinoma, but can also be used to reveal the biological characteristics of the tumors by functional imaging.

OBJECTIVETo investigate the role of autophagy inhibitor chloroquine (CQ) in the proliferation of pulmonary arterial smooth muscle cells (PASMCs) in hypoxia conditions.

METHODSThe following groups in this study were set up: control group, hypoxia group, 50 micromol/L CQ + hypoxia group, 50 micromol/L CQ group. The viability of PASMCs in every group was detected by MTT assay. Autophagic vacuoles in the cells were observed by MDC staining. Protein expression of microtubule associated protein light chain 3 (LC3) was measured by Western blot. Migration of PASMCs was detected by wound healing assay.

RESULTSCompared with control group, no effect on the viability of PASMCs was observed treated by CQ alone. In 1% hypoxia group, cell viability increased significantly compared with that in control group. The number of autophagic vacuoles and the rate of cell migration and also protein expression of LC3-II were also markedly increased. Compared with hypoxia group, addition of CQ increased the number of autophagic vacuoles and the levels of LC3-II protein, but decreased the proliferation and migration of PASMCs.

CONCLUSIONHypoxia could activates autophagy and contributes to proliferation and migration of PASMCs, and autophagy inhibitor CQ could decrease the effect of hypoxia on PASMCs through inhibiting autophagy process.

OBJECTIVETo investigate the correlation between 18F-fluorodeoxyglucose (18FDG) uptake of primary lesions during PET-CT (positron emission tomography and computed tomography) examination and clinicopathological parameters such as the tumor length, depth of invasion, differentiation of the primary lesions and lymph node metastasis status in the patients with esophageal carcinoma.

METHODSFrom June 2004 to November 2006, 68 operable esophageal carcinoma patients were enrolled into this study, and all had a whole body 18FDG PET-CT scan before operation. The maximum standardized uptake value (SUVmax) of the primary lesions was measured. The tumor length, depth of invasion, differentiation of the primary lesions and lymph node metastasis status were determined by postoperative pathological examination. The correlation between the standardized uptake value (SUV) of primary lesions and the above mentioned clinicopathological parameters was analyzed.

RESULTSThe overall length of primary lesion was positively correlated with SUVmax (r=0.512, P=0.01). Depth of invasion was also positively correlated with SUVmax (r=0.860, P=0.000). There was a statistically significant difference in SUVmax between poorly differentiated group and moderately or well differentiated group (r=0.781, P=0.000), and also between the groups with or without lymph node metastasis (r=0.852, P=0.000).

CONCLUSIONThe tumor length, depth of invasion and differentiation of the primary lesions of the esophageal carcinoma are all positively correlated with maximum standardized uptake value of 18FDG. The more poorly differentiated lesions show a higher 18FDG maximum standardized uptake value. The lesions with lymph node metastasis have also a significantly higher 18FDG maximum standardized uptake value than those without lymph node metastases.
