Objective: To probe into the relationship between integrin β1 expression in human cervical carcinoma HCE1 multicellular spheroids (HCE1/MCS) and their invasion into human umbilical vein endothelium cells (HUVEC), so as to assess the inhibitory effect of anti-integrin β1 monoclonal antibody P5D2 on the invasion of HCE1/MCS into HUVEC. Methods: A model of HUVEC monolayer invaded by HCE1/MCS was established (in brief, the HCE1 invading model). Morphology changes of the HCE1 invading model were observed under inverted microscope and analyzed by Motic Med System after P5D2 treatment. The expressions of β1 integrin on HCE1 monolayer cells, HCE1/MCS, HVUEC monolayer cells, and P5D2-treated HCE1 invading models were measured by immunocytochemistry SABC assay. Results: A HCE1 invading model was successfully established. The HCE1/MCS proliferated rapidly after culture, and on the 7th day the invading area of HCE1/MCS was 40.42 folds larger than the original HCE1/MCS. Invading areas of P5D2-treated HCE1/MCS were significantly smaller than that of the control group after 1, 4, 7 day (P<0.05, or P<0.01), with the invading area after 7 days reduced by (84.68±0.08) % compared with the control group. Integrin β1 expression in HCE1/MCS was significantly higher than that in HCE1 monolayer cells (P<0.01), and the expression was negative in HUVEC. Integrin β1 expression in P5D2-treated HCE1/MCS was significantly lower than that the in untreated HCE1/MCS (P<0.01). Conclusion: Upregulated expression of integrin β1 in HCE1/MCS and HCE1 invading model may be associated with their enhanced adhesion and invasion abilities. Anti-integrin β1 monoclonal antibody P5D2 can partially block the invasion of HCE1/MCS into HUVEC.

Objective This study was to investigate the Chlamydia trachomatis (CT) infection rate in cervical secretion of early pregnant and secondary sterility women. Method CT-DNA in the cervical secretion of the early pregnant, the secondary sterility, and the control women was detected with polymerase chain reaction (PCR). Results The infection rates of CT in the early pregnant and secondary sterility women (14.28% and 13.33%)were higher than in the control women (3.33%, P<0.05),and there was no significant difference between the former two groups (P>0.05). Conclusion There are higher infection rates in the early pregnant and secondary sterility women.Detecting CT and treating in the perinatal period are needed in the early pregnant women who want to be pregnant again.

Objective To explore the effectiveness of mindfulness-based four-step approach to obsessive compulsive disorder. Methods A total of 82 patients with obsessive compulsive disorder were divided into control group and study group with 41 cases each by admission order. The patients in control group were given routine drug treatment and nursing, and the patients in study group were given mindfulness-based four-step approach based on control group. The indexes were evaluated by Yale-Brown Obsessive Compulsive Scale, Hamilton Depressive Scale, Hamilton Anxiety Scale, Short Form 36 questionnaire before and after intervention.

Objective To observe the effects of puhnonary rehabilitation on the symptoms and quality of life of persons with chronic obstructive pulmonary disease (COPD).Methods COPD patients were recruited from a hospital and community health centers and given pulmonary rehabilitation in the community.The rehabilitation program included health education and nutrition guidance,medication,breathing exercises,and physical exercise.Each patient was followed up every 4 weeks by telephone.The outcome measures included pulmonary function (FEV1%,FEV1/FVC%),St George's questionnaire (SGRQ),the Medical Research Council scale (MRC),Borg scoring,evaluation of anxiety and depression,the six-minute walk test (6MWT),and an evaluation of nutritional status.All of the patients were observed for one year.Results A total of 85 patients completed the program and were included in the final statistical analysis.There was no difference in FEV1 % before and after rehabilitation.Six-minute walking distance improved significantly in statistical terms but the average increase was only from (416.1 ±99.84)m to (437.51 ±116.17)m.The SGRQ scores decreased by an average of 4.8 points after a year of rehabilitation,with significant improvements among the moderately and severely impaired.Incidents of COPD exacerbation also decreased significantly.Patients with a low body mass index had the greatest SGRQ score improvments.Few patients showed depression or anxiety in this research population.Conclusions Pulmonary rehabilitation in the community can improve exercise tolerance and the quality of life for persons with COPD,reducing incidents of acute exacerbation.Patients may benefit from such pulmonary rehabilitation regardless of disease severity.The compliance was good despite the infrequent monitoring.Pulmonary rehabilitation in the community is worthy of more widespread use.

Methods The expression of KISS-1 in 55 cases of normal endometrium as well in 46 cases of ectopie endometriurn with endometriosis were detected by immunohistochemicai EliVision plus method. Results The positive expression rates of KISS-1 in ectopic endometriotic tissues and in normal endometri-urn were 30.43 % and 63.64 % respectively ,and the positive expression rates in ectopic endometriotic tissues signifi-cantly lower than those in the normal endometrium( P< 0.01, P < 0.05). Conclusion The decreased expression of KISS-1 may be related to the mechanism of endometriosis.

Objective:To study the effect of interleukin-11(IL-11),ciliary neurotropic factor (CNTF) and transforming growth factor-β (TGF-β) on the hGH gene promoter activity in rat pituitary MtT/S cells and the interaction with pituitary-specific transcription factor Pit-1.Methods:Stable transformed MtT/S cell line which contains hGH gene promoter -484-30 bp and luciferase reporter gene firstly established,then the concentration of GH in the medium and lysate of MtT/S cells and luciferase activities in MtT/S cells were measured after treatment these cells with the above cytokines,the effects of cytokines on secretion and synthesis of GH,and the promoter activity of the hGH gene were observed.Results:The results showed that IL-11(20 nmol/L),CNTF(10 nmol/L) and TGF-β(5 nmol/L) regulated secretion and synthesis of GH,and the luciferase expression in stable transformed MtT/S cells.IL-11 and CNTF had the stimulatory effect,whereas TGF-β had the inhibitory effect.Neither overexpression of Pit-1 nor inhibiting Pit-1 expression affected the regulatory role of these cytokines.Conclusion:IL-11,CNTF and TGF-β regulate the GH production in pituitary MtT/S cell line by regulating the hGH gene promoter activity.Pit-1 may not be involved in these actions.

Objective To discuss the significance of high-risk human papilloma virus ( HR-HPV) detection by hybrid capture 2 (Hc-2) in managing the women with atypical squamous cell of undetermined significance (ASCIIS) and low grade squamous intraepithelial lesion (LSIL) of thin prep liquid-based cytology (TCT). Methods One hundred and seventy-eight women with ASCUS and 108 women with LSIL were studied. The infection of HR-HPV in the women was analyzed. And sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were used to evaluate the significance of HR-HPV detection by Hc-2 in managing the women with ASCUS and LSIL of TCT. Results Sensitivity,specificity, PPV and NPV of HR-HPV DNA detection by Hc-2 in screening CIN II or above in ASCUS were 89.83% (53/59),53.78% (64/119), 49.07% (53/108), 91.43% (64/70) respectively,and in LSIL were 97.62%(41/42),22.73%(15/66), 44.57%(41/92), 93.75%( 15/16) respectively. Conclusion HR-HPV detection by Hc-2 is an effective measure in managing the women with ASCUS and LSIL of TCT.
