Objective The aim of this study was to evaluate the effect of marriage quality intervention in peer education model among women with breast cancer.Methods Marginal quality questionnaire was used to assess in the intervention and control groups during the perioperative period.There had 120 breast cancer patients in the intervention group and 135 normal subjects for control group.The patients were followed by the peer education model and the marriage and quality education during the chemotherapy period.The marriage quality questionnaires were carried out one year after the operation.Results Marital satisfaction(38.73±7.45),couples communication(38.12±7.03)and sex life(36.77±6.96)were significantly higher than those of the patients who participated in the traditional health education group after 1 year of operation.The control subjects with traditional health education had lower satisfaction of marital life(32.59±9.29),husband and wife communication(34.41±7.39)and sexual life(32.59±6.59)in one year after surgery(P<0.001).The scores of marital satisfaction,husband and wife communication,and sex scores were significantly lower in patients with traditional health education after 1 year of operation(P<0.001).Conclusion Marriage quality interventions in the peer education model can effectively affect the marital quality of postoperative patients with breast cancer.

Objective To investigate the effect of different subtypes of fractionated doses on multidrug resistance in ovarian cancer cells.Methods The human ovarian cancer cell lines SKOV3 and its drug-resistant subtype SKVCR were divided into four groups i.e., sham-irradiated, single dose (10 Gy),fractionated dose (2 Gy × 5 ) and multi-fractionated dose (1 Gy × 2 × 5).Cell sensitivity to vincristine(VCR),etoposide ( VP-16),pirarubicin (THP) and cisplatin (DDP) was measured by MTT assay.Western blot was applied to detect the expression of P-gp after irradiation.Results The doubling time of SKVCR was about 1.8-fold of that of SKOV3 cells.P-gp was expressed in SKVCR but not in SKOV3.IC50 values of SKVCR were higher than those of SKOV3.To SKOV3 cells,single dose irradiation decreased cell sensitivity to THP and DDP and fractionated irradiation decreased cell sensitivity to VCR,THP and VP-16.Multi-fractionated irradiation decreased cell sensitivity to VP-16.In SKVCR cells,all these irradiation treatments increased cell sensitivity to VCR and VP-16 but not to DDP.In addition,single and fractionated irradiation decreased P-gp expression in SKVCR cells.Conclusions Single,fractionated and multi-fractionated radiation induced chemotherapy resistance in SKOV3 cells,while reversed drug resistance to VCR and VP-16 in SKVCR cells.

Objective To investigate the clinical value of thinprep cytology test(TCT) combined with colposcopy in diagnosis of cervical lesion. Methods Retrospective analysis was conducted in 174 females with abnormal cervical smear. All the patients underwent colposcopy to screen the cervical lesions. According to the pathological results,the clinical value of TCT and colposcopy was analyzed and compared. Results In the 174 cases with abnormal cervical smear,the positive rate of atypical squamous cells(ASC) was 27. 0% (47/174). There were 92 low grade squamous intraepithelial lesion (LSIL) (52. 9%) ,33 high grade squamous intraepithelial lesion (HSIL) (19. 0%) and 2 squamous cell cancinoma (SCC) (1. 1%) . According to the diagnosis by biopsy and pathology,the positive rate of benign cervical cell(BCC) was 16. 1% (28/174) .cervical intraepithelial neoplnsia (CIN) I 42. 0% (73/174), CIN II 18.4% (32/174), CIN ffl 21. 8% (38/174) and SCC 1. 7% (3/174) . The coincidence rate of TCT and pathology was 83. 9% (146/174). Conclusions TCT and colposcopy are a practical approach for detecting cervical lesion. TCT combined with colposcopy is the optimal screening approach for cervical lesion, which can enhance the sensitivity and specificity of the diagnosis of cervical lesions.

AIM: To study the protective effects of basic fibroblast growth factor (bFGF) on myocardial ischemia in rats and their underlying mechanism. METHODS: A rat myocardial ischemic injury model was established by left coronary artery ligation. The rats were killed at 2 h, 4 h, 8 h after coronary artery occlusion. The samples of blood and myocardium were collected for observing the expression of Bcl-2 and Bax in myocardial cells and the changes of superoxide dismutase (SOD) or myocardial enzymes. RESULTS: The amount of Bcl-2 protein expression of myocardial cells in ischemia + bFGF group was significantly higher than that in ischemia+saline group (P

Aim: To observe the influence of high fat-high sucrose diet and chronic stress on insulin resistance. Methods: Male rats were divided into four groups: control, high fat-high sucrose diet( HFSD), chronic stress( CS), high fat-high sucrose diet plus chronic stress( HFSD + CS). After feeding the animals for 10 weeks, fat, glucose and insulin concentrations in blood and PPAR-α mRNA expression in liver were examined, and glu-cose infusion rate was detected by a hyperinsulinemic euglycemic clamp experiment. Results: Insulin resistance was observed in all three treated groups, showing the highest in the HFSD + CS group. Dyslipidemia, hypergly-cosemia, hyperinsulinism and the decrease of PPAR-α mRNA expression in liver were also shown in all treated groups. There was an obvious interaction of insulin resistance, hyperglycosemia and high FFA between high fat-high sucrose diet and chronic stress. Conclusion: Combination of high fat-high sucrose diet and chronic stress could promote the development of insulin resistance, which is likely due to the high level of serum FFA.

BACKGROUND:Studies have reported that taurine has a certain therapeutic effect on the disease of various systems, such as nervous system, cardiovascular system, immune system and digestive system. The liver is the main place, also the important target organ, of taurine metabolism. Therefore, the relationship between taurine and hepatopathy has become a hot topic in recent years. OBJECTIVE:To investigate the influence of taurine on superoxide dismutase and malondialdehyde expression in the liver tissue of rat models of liver fibrosis induced by carbon tetrachloride. METHODS:Thirty male C57B/L rats of SPF grade were randomly and evenly divided into blank control, model and taurine groups. Rats in the blank control group were intraperitonealy injected with 100% peanut oil of 1 mL/kg, twice a week, in total 10 weeks. Rats in the model group were intraperitonealy injected with peanut oil of 1 mL/kg containing 20% carbon tetrachloride, twice a week, in total 10 weeks. Rats in the taurine group were intraperitonealy injected with peanut oil of 1mL/kg containing 20% carbon tetrachloride, twice a week, in total 10 weeks, and were intragastricaly administered taurine of 500 mg/kg per day starting from the 3rd week til the 10th week. RESULTS AND CONCLUSION:Compared with the blank control group, the serum levels of hyaluronic acid, laminin, typeⅢ procolagen, typeⅣ colagen, alanine aminotransferase, aspartate aminotransferase were significantly increased (P < 0.05), the level of superoxide dismutase in the liver tissue was lowered (P < 0.05), the level of malondialdehyde in liver tissue was significantly increased (P < 0.05), and liver index was increased (P < 0.05) in the model group. Pathological examination showed that there were necrosis of liver cels, fat vacuoles, fibrous tissue hyperplasia and inflammatory cel infiltration in the rats of the model group. Compared with the model group, the serum levels of hyaluronic acid, laminin, typeⅢ procolagen, typeⅣ colagen, alanine aminotransferase, aspartate aminotransferase were significantly lowered (P < 0.05), the level of superoxide dismutase in the liver tissue was significantly increased (P < 0.05), the level of malondialdehyde in the liver tissue was significantly lowered (P < 0.05), and liver index was significantly decreased (P < 0.05) in the taurine group. Pathological examination showed that there were no inflammatory cel infiltration, fat vacuoles, and fibrous tissue deposition in the liver tissue. The results indicate that taurine can decrease the contents of superoxide dismutase and malondialdehyde, and relieve the degree of liver fibrosis induced by carbon tetrachloridevia exerting its antioxidative effects.

Objective To analyze the misdiagnosed cases of the nodular goiter (NG)in real-time contrast-enhanced ultrasound(CEUS),in order to improve the diagnostic accuracy of NG.Methods Two-hundred and sixty-five cases of NG CEUS images,especially the 48 nodules in 44 misdiagnosis cases,were retrospectively analyzed to find out the main reasons of the misdiagnosis.In addition,the factors which effected the results of CEUS such as size,number and calcification of NG nodules were summarized.Results There were 42 nodules misdiagnosed as thyroid cancer,5 nodules misdiagnosed as thyroid adenoma and 1 nodular goiter misdiagnosed as subacute thyroiditis in 874 nodular goiter cases.The misdiagnosis rate of nodular goiter was 5.49% (48/874)by the diagnostic criterion of homogeneous enhancement in CEUS.The differences size and calcification of nodules had a significant impact on CEUS.The misdiagnosis rate of the NG nodules with major diameter less than 10 mm was much higher than that of more than 10 mm,the misdiagnosis rate of NG nodules with coarse calcification was much higher than the situation of microcalcification(P <0.05).Conclusions Major diameter less than 10mm and coarse calcifications of NG nodular are the main factors which influence the results of CEUS.
