Objective To investigate the curative effects of different types of hysteroscopic surgery for endometrial polyps. Methods A total of 327 cases by different ways of hysteroscopic surgery for endometrial polyps from Nov 1999 to Nov 2004 were followed up. The mean age was (40?6) yea rs. The mean follow-up was( 3.0?0.6) years. Among 228 polyps patients in s exual maturity without desire of maintaining fertility, 53 (group A) underwent p olypectomy with electrosurgical vaporization, and 175 cases (group B) did polype ctomy with endometrial resection. Fifty-four (group C) cases (19 cases of infe rtility), who desired future childbearing, did polypectomy with endometrial rese ction of superficial layer near the polyps. Forty-five postmenopausal patients(group D) did polypectomy with endometrial coagulation. Results The time of operation: group A (15.1?0.8) second,group B (19.7?0.7) s econd,group C (20.9?0.7) second,and group D (22.1?0.8) second. None of polyps recurred for the patients of groups A and D after operation, and the recu rrent rate of groups B and C was 1.7% and 7.4%. There were no cases with amen orrhea in group C, who hoped to keep the function of fertility, but the recurren t rate of polyps was higher than other three groups. Of 19 cases of infertility , 14 cases became pregnant after the surgery. Conclusion It is feasible to select different hysteroscop ic surgery for endometrial polyps,according to different ages and the desire of childbearing of the patients.

Objective To investigate the relationship between polymorphism of codon54of the man-nose-binding lectin(MBL)gene and serum concentration in patients with systemic lupus erythematosus(SLE).Methods The MBL gene54(GGC/GAC)polymorphism was analyzed by polymerase chain reaction and restrict fragment length polymorphism(PCR-RFLP)in44patients with SLE and45healthy controls.Serum levels of MBL were also determined by ELISA.Results The frequencies of the wild homozygons(GGC/GGC)and het-erozygotse(GGC/GAC)of MBL codon54did not differ significantly between patients(GGC/GGC71%,GGC/GAC27%,GAC/GAC2%)and healthy controls(GGC/GGC78%,GGC/GAC22%,GAC/GAC2%).The serum MBL level of the three genotypes was(1.8?0.6)mg/L(n=31),(1.5?0.6)mg/L(n=12),1.17mg/L(n=1)respective-ly in SLE group;(3.0?1.0)mg/L(n=35),(2.2?1.0)mg/L(n=10)in control group.The(GGC/GGC and GGC/GAC)genotypes in SLE group were significantly lower than the control group.Conclusion The condon54mutation of the MBL gene may be not associated with low serum level of MBL in patients with SLE.

Objective The purpose of this study was to investigate the knowledge，attitude and behaviors (KAB) of rural residents. Methods A correlative-descriptive design was used for the study. A cluster sampling of 1952 rural residents aged 18-60 years old in 8 villages of Lantian county was selected. Results The results showed as follows. The total correct rate of knowledge was 50.9%; 43.5% believed that the prevalence of HIV/AIDS in China indicated decline of the moral value; 71.3% never use condom when having sex in the past;There were positive relationships between knowledge and attitude,using condoms during sex and using condoms during first sex respectively (P<0.01). Conclusion The attitude and behavior on HIV/AIDS of the rural residents are largely determined by their knowledge.

Background and purpose:MicroRNA (miRNA, miR) plays an important regulatory role in cancer. miR-222 is reported to be up-regulated in various tumors, but its role in renal cell carcinoma (RCC) remains unclear. In this study, we detected the expression of miR-222 in both RCC and adjacent tissue samples. The aim of this study was to investigate the role of miR-222 in RCC. Methods:The expression levels of miR-222 in RCC tissue samples were quantified by quantitative real-time polymerase chain reaction (qRT-PCR). DDIT4 and LC3-Ⅱ protein expressions were determined by Western blot. Dual luciferase assay was performed to verify the target of miR-222. EGFP-LC3 microscopy assay was performed to assess autophagy. Results:Results from qRT-PCR showed that the expression of miR-222 was up-regulated in RCC tissues. Knockdown of miR-222 with speciifc antagomiR decreased the cell viability of 786-O cells, whereas overexpression of miR-222 increased the cell viability (P<0.01). The levels of DDIT4 were up-regulated in 786-O cells transfected with miR-222 antagomiR, whereas overexpression of miR-222 induced the down-regulation of DDIT4 expression. Data from dual luciferase assay indicated that miR-222 directly targeted the expression of DDIT4. Consistently, the expression of DDIT4 in RCC tissues was down-regulated compared with adjacent tissues. Knockdown of miR-222 in 786-O cells induced a signiifcant increase of autophagosome formation and LC3 lipidation.These results supported that miR-222 could inhibit autophagy in RCC cells, which may affect the clinical characteristcs of RCC. Conclusion: miR-222 is up-regulated in RCC and can inhibit the autophagy of RCC cells through down-regulating the expression of DDIT4.

Methods:CCK-8 assays were performed to analyze the effects of hinokitiol on the proliferation of 786-O cells. The apoptosis rate was determined by flow cytometry. EGFP-LC3 microscopy assays were performed to assess the autoph-agy flux. Cleaved Caspase-3, LC3, and P62 were detected by Western blot. Results: Hinokitiol could inhibit the proliferation of the 786-O cells and could induce cell apoptosis via Caspase pathway. Hinokitiol induced the autophagy of 786-O cells, increased LC3 ex-pression, and downregulated P62 expression. Conclusion: Hinokitiol can inhibit the proliferation of 786-O cells and can induce cell apoptosis via autophagy induction.

Objective To explore the role of the DACT2 gene in the occurrence and development of renal cell carcinoma(RCC).Methods The samples of RCC tissues and corresponding tumor-adjacent tissues after radical operation and normal kidney tissues were collected.The methylation specific PCR (MSP) and real time fluorescence reverse transcriptase-PCR (RT-PCR) methods were adopted to detect the methylation status and mRNA expression of DACT2.The streptavidin-peroxidase (SP) method labeled by immunohistochemistry peroxidase was used to examine the expression of β-catenin protein.Then the relationship between DACT2 gene methylation status and mRNA expression with the clinicopathologic characteristics was analyzed.The relationship between DACT2 gene methylation with mRNA and β-catenin expression was analysed,as well.Results The DACT2 mRNA relative expression level in RCC tissues was 0.427±0.025,which was significantly lower than (0.801±0.047) in tumor-adjacent tissues and (0.872±0.022) in normal tissue,the positive rate of DACT2 gene methylation in RCC tissues was 45.76%,which was significantly higher than 6.78% in tumor-adjacent tissues and 5.08% in normal tissues,the difference was statistically significant (P<0.05),while the difference between tumor-adjacent tissues and normal tissues had no statistical significance (P>0.05).The DACT2 gene mRNA expression level in RCC tissues and promoter area methylation occurrence rate had no obvious correlation with the clinical data such as patients age,gender,tumor size,clinical stage and Fuhrman grade (P>0.05).The DACT2 gene mRNA relative level in the methylation group was lower than that in the non-methylation group,the difference was statistically significant (P<0.05).The expression rate of β-catenin protein in cytoplasma in RCC tissues was higher than that in the tumor-adjacent tissues and normal tissues,the difference was statistically significant (P<0.05),moreover,DACT2 gen methylation had a positive correlation with β-catenin protein expression (r=0.324,P=0.012).Conclusion The decrease of DACT2 gene promoter area methylation and mRNA relative expression level may participate in the RCC occurrence,but has no relationship with RCC clinical progression.Methylation occurred in DACT2 gene promoter area may be one of reasons causing mRNA relative expression decrase.DACT2 gene methylation occurrence in RCC tissue might be related to the high expression of β-catenin.
