Objective To investigate the expressions of DKK1,SFRP4 and Wnt1 in cervical squamous cell carcino-ma(SCC), and the clinical significance thereof. Methods There were 76 samples of cervical squamous cell carcinoma were included in SCC group and 36 benign uterine resection specimens were control group (NC). The immunohistochemical meth-od was applied to detect the expressions of DKK1,SFRP4 and Wnt1 in two groups. Results The expression of DKK1 was significantly lower in SCC group than that in NC group (P＜0.05). The expression levels of SFRP4 and Wnt1 were significant-ly higher in SCC group than those of NC group (P＜0.05). There were significant differences in the expressions of DKK1, SFRP4 and Wnt1 between samples of different clinical staging, differentiation, sizes of tumor and lymph node metastasis (P＜0.05). The expression of DKK1 was negatively correlated with SFRP4 and Wnt1 in SCC group (P＜0.05). The expression of SFRP4 was positively correlated with Wnt1 in SCC group (P＜0.05). Conclusion The roles of SFRP4 and Wnt1 are syn-ergistic interactions in the development of SCC. DKK1 is an inhibiting factor of SCC.

Objective To observe the changes of LoVo cell growth by galectin-1.Methods Eukaryotic expression vector of galectin-1 was constructed and transfected into LoVo cells using lipofectamineRM 2000.Immunochemistry was employed to detect galectin-1 expresson.LoVo cell proliferation and apoptosis were observed.Results Galectin-1 eukaryotic expression vector pEGFP-C1/GAL1 was successfully constructed.Three cell clones,p-GAL1-LoVo and p-LoVo,transfected with pEGFP-C1/GAL1 and pEGFP-C1 correspondingly,and LoVo were cultured successfully.Galectin-1 expression downregulated Bcl-2 level only occurring in p-GAL1-LoVo cells.p-GAL1-LoVo cell proliferation was similar to p-LoVo and LoVo cells,but p-GAL1-LoVo cell apoptosis was increased(9.61?0.56)%,as compared with p-LoVo and LoVo cells,[(3.56?0.53)% and(3.46?0.46)% respectively](P

Objective To construct the RNA interference (RNAi) eukaryotic expression vectors of galectin-1, and establish the LST-R1 cell lines stably transfected by RNAi vectors. Methods Two pairs of small interfering RNAs (siRNA) targeting to galectin-1 mRNA (GenBank: NM002305) were designed. The corresponding single-strand short hairpin interfering RNAs (shRNA), containing BamH Ⅰ, Hind Ⅲ sites and a 9nt hairpin structure, was synthesized and annealed. The annealed product and the linear eukaryotic expression plasmid pSuperior-puro, which were digested with Bgl Ⅱ and Hind Ⅲ, were ligated by T4 ligase to set up the interfering system. The recombined plasmid was identified with EcoR Ⅰand Hind Ⅲ enzyme digestion and sequencing, and co-transfected to LST-R1 cells with pcDNA6/TR with Lipofectamine2000. Positive clones were selected with 0.8?g/ml puromycin. After incubated with 4?g/ml tetracyclin for 48 hours, RT-PCR, Western blotting and immunochemistry were employed to determine galectin-1 mRNA and protein levels. Results Sequencing results suggested that the nucleotide sequence and read frame of RNAi eukaryotic exprssion vector of galectin-1, p-shRNA1 and p-shRNA2 were perfect. Stably transfected LST-R1 cell lines of p-shRNA1-LST and p-shRNA2-LST were established. The relative values of galectin-1 expression in LST-R1 cells, p-shRNA1-LST cells, p-shRNA2-LST cells and p-LST cells by RT-PCR were 0.616, 0.298, 0.373 and 0.641, respectively, and 1.00, 0.07, 0.38 and 0.97 by Western blotting. The p-shRNA1 gave the best interfering effect, which was in conformity with the results of immunochemistry measurement. Conclusions RNAi eukaryotic expression vector of galectin-1 mRNA has been successfully constructed. Establishment of the stably transfected LST-R1 cell lines may lay a foundation to explore the roles of galectin-1 in laterally spreading tumor.

Objective To explore the effects of group psychotherapy on breast cancer patients. Methods 80 outpatients with breast cancerwho did not participate in the Rukang Salon (control group) and 100 outpatients participated (intervention group) were surveyed withquestionaire. Results The incidence of psychological distress was 36.8% in the control group and 21.1% in the intervention group ( χ2=5.02,P=0.03). In the intervention group, the efficacy of those without psychological distress (236.86±35.17) was significantly higher than thosewith psychological distress (214.21±26.52), (t=2.61, P=0.01). There were significant differences in those 5 factors: group cohesion, universality,interpersonal learning, guide instructions, and hope remodeling. Top 5 factors in scores reported were interpersonal learning, hopingremodeling, group cohesion, guide instructions, and exist consciousness. Conclusion Group psychotherapy can significantly reduce the psychologicaldistress in rehabilitating breast cancer patients. Group cohesion, universality, interpersonal learning, guide instructions, hope remodelingand exist consciousness may play important roles.

Objective To investigate the life satisfaction and its related factors in primary caregivers of breast cancer patients. Methods The Life Satisfactory Index A (LSIA) and self-administrated questionnaire were used. The life satisfaction between breast cancer patients'primary caregivers and breast benign patients' primary caregivers were compared. The factors of the life satisfaction in primary caregivers of breast cancer patients were analyzed. Results The life satisfaction was poorer in the breast cancer patients' primary caregivers than in the breast benign patients' primary caregivers (P<0.01). The life satisfaction in the breast cancer patients' primary caregivers was correlated with the stage of breast cancer, course of disease, primary caregivers' age and family monthly income (P<0.05). Conclusion The life satisfaction in breast cancer patients' primary caregivers is worse and is related with stage of breast cancer, course of disease, primary caregivers' age and family monthly income.

Objective To investigate the different expression of microRNA-155 (miR-155) and cysteine-rich 61 (CYR61) in human placentas between severe preeclamptic and normal pregnancies.Methods Placentas were obtained from severe preeclamptic and healthy control pregnant women (n=18 for each group) at 36～40 gestational weeks. The expressions of miR-155 and CYR61 mRNA were assessed by real-time quantitative reverse transcription-polymerase chain reaction, and the levels of CYR61 protein were tested by Western blot. Results Compared with the control group, the miR-155 expression was increased in placentas from severe preeclampsia groups ( 165. 7 ± 16. 4 vs 527.9±49.1,t=7.00, P＜0.01), and the CYR61 mRNA expression (31.7±2.7 vs 16.4±1.2,t=5.10,P＜0. 01), as well as the CYR61 protein expression (36.4±1.5 vs 19.7±1.2,t=36.26, P＜0.01 ) were decreased. There was a significantly negative correlation between the expression of miR-155 and CYR61 mRNA within both groups (preeclamptic group: r=-0.52, P＜0.05;control:r=-0.57, P＜0.05). Conclusions Up-regulation of placental miR-155 in severe preeclampsia may be related to the decreased expression of CYR61. Both miR-155 and CYR61 may contribute to the disorders of placental angiogenesis in severe preeclampsia in human.

Objective To investigate the miss rate of adenoma with colonoscopy and assess the features and risk factors for missed diagnosis.Methods Patients with colorectal adenoma received a second colonoscopy within 120 days after adenoma was detected and removed on the initial colonoscopy.The findings of two colonoscopies were reviewed and analyzed.The features of adenoma (including size, location, shape, number and pathology) , clinical characteristics of patients (including age, sex, reasons of colonoscopy, history of diverticular disease, history of abdominal or pelvic surgery and colonoscopy with sedation) and endoscopists were recorded.Miss rate and features of different types of missed adenoma were analyzed.We also assessed the effects of adenoma features, patients' characteristics and endoscopists on missed diagnosis of adenoma.Results Adenoma missed diagnosis was found in 271 patients out of 809 recruited subjects (33% ).A total of 425 adenomas were missed out of 2134 (20% ) adenomas detected by repeated colonoscopy.A large diameter was associated with a decrease in the miss rate for adenoma (P < 0.01).Conversely , sessile or flat shape (P < 0.01) , locations at sigmoid, hepatic flexure, cecum and ascending colonic ( P < 0.05) were significantly associated with a higher miss rate of adenoma, as was the number of adenomas (P <0.01).A higher adenoma missed diagnosis rate was observed in beginner colonoscopists, as compared with experienced ones (P < 0.01).Conclusion A marked miss rate of adenoma exists on colonoscopy, which is significantly associated with the size, shape, location and number of adenomas and endoscopists.
