Objective: It has been found that the expression of Hedgehog signaling molecule Gli1 can inhibit the activity of estrogen signaling pathway. The present study is to observe the effect of estrogen receptor α (ERα) on the transactivation and expression of Gli1 in breast cancer cells, so as to study whether there is a cross talk between the two pathways. Methods: Using luciferase reporter gene transactivation analysis, we cotransfected MCF-7 cells with pGli-BS-luc, PcDNA3. 1-Gli1, pRL-CMV, pSG5-ERa or equimolar amounts of pSG5 vector. Then the cells were subjected to Luciferase Assays to analyze the change of Gli1 transactivation. The mRNA and protein expression of Gli1 following ectopic overexpression of ERa was also analyzed by quantitative real-time PCR and Western blotting analysis. Results= Expression of ERα induced the luciferase activity in a dose-dependent manner. ERα at 500 ng/well increased the activity of luciferase by 3.5 folds (P<0.001). The luciferase activity had no obvious changes after estrogen treatment. Overexpression of ERα increased the expression of Gli1 mRNA by 2 folds (P< 0.01), and obviously increased the expression of Gli1 protein. Conclusion: Overexpression of ERa in MCF-7 cells can greatly increase the transactivity of Gli1 and increase its expression, which indicates that there is a cross talk between the two transcription factors in breast cancer cells.

Objective To explore the association between C reactive protein (CRP)with prostatic cancer (PCa)and benign prostatic hyperplasia (BPH).Methods Retrospective analysis the 110 patients of the First Affiliated Hospital of Zhejiang University In January 2010 to August 2012 whose TPSA>4 ng/ml,postoperative pathology confirmed the diagnosis of 54 cases of prostate cancer,5 6 cases of benign prostatic hyperplasia.Detected serum CRP levels by using transmission turbidim-etry and TPSA levels by using chemiluminescence immunoassay of 54 PCa and 56 BPH patients.According to the Gleason score,PCa patients were divided into high-risk and low-risk PCa two groups,the differences among high-risk PCa,low-risk PCa and BPH groups were analyzed by nonparametric statistics analysis.Results The CRP level of high-risk PCa was 4.20~2.12 mg/L,the CRP level of low-risk PCa was 1.90~0.91 mg/L and the CRP levels in BNP patients was 1.49±0.87 mg/L,the high-risk and low-risk PCa serum CRP level obviously higher than that of patients with BPH,the differences were statistically significant (P<0.05).Conclusion Serum CRP levels of PCa patients were increased significantly,espe-cially in high-risk PCa patients.

Objective To observe the expression of resistin mRNA and protein in adipose tissues of obese rats,and to explore the correlations between resistin and obesity,insulin resistance.Methods Thirty SD rats were divided into control group(n=15) and high-fat diet group(n=15).The rats in control group recieved common forage.The obese and insulin resistance models were induced with high-fat diet in SD rats.The plasma insulin level was determined by double antibody radioinimunity analysis,and automatic biochemistry analyzer in plement was used to detect the plasma free fatty acid.After 11 weeks,glucose tolerance test was carried out to determine blood glucose levels at intervals(0,30,60,90,120 min).Resistin mRNA from fat pads tissue was extracted by RT-PCR,and then its protein was detected by Western blot.The data were analyzed statistically by SPSS 11.5 software.Results After 11 weeks,the rats′ weight in high-fat diet group increased obviously than that of control group,as well as fasting blood glucose,free fat acid homeostasis model assessment of insulin resistance(HOMAIR) and the glucose tolerance in high-fat diet group reduced greatly.The resistin mRNA and protein in white adipose tissues were significantly higher in the obese mice than those of control group(Pa

Objective To study the clinical application of proportional assisted ventilation (PAV) in the treatment of neonatal respiratory failure.Method From March 2011 to October 2013,a retrospective study was conducted on newborns receiving ventilation therapy for respiratory failure.The newborns were assigned into PAV group and synchronized intermittent mandatory ventilation (SIMV) group.Arterial blood pH 、partial pressure of arterial oxygen (PaO2)、partial pressure of arterial carbon dioxide (PaCO2) and oxygenation index (OI) were compared at the time before ventilation and 2 h,6 h,12 h,24 h after ventilation.The frequency of sedative usage and average time of ventilation between the two groups were compared.Result A total of 30 cases were enrolled in the PAV group and the SIMV group respectively.Before ventilation,no statically significant differences existed on blood pH[(7.13 ± 0.12)、(7.14 ±0.11)],PaO2[(41.1 ±8.9),(40.8±8.8) mmHg],PaCO2[(76.4±12.6),(73.2±13.5) mmHg]and OI between the two groups (P ＞ 0.05).2 h after ventilation,the blood pH [(7.25 ± 0.17)、(7.23 ± 0.15)],PaO2 [(51.0 ± 5.6)、(48.6 ± 5.3) mmHg] and OI were significantly improved,while PaCO2 [(66.3 ± 8.7)、(64.0 ± 7.5) mmHg] decreased.Comparing with data before ventilation,those parameters were statistically improved at each time point after ventilation (P ＜ 0.01).But no statistically differences existed between the two groups at the same time (P ＞ 0.05).Sedatives were used (2.3 ± 1.2)times/case in PAV group and (3.9 ± 2.2) in SIMV group,with statistically differences between the two groups (P ＜ 0.05).Average duration of ventilation were (5.1 ± 1.9) d in PAV group and (5.4 ± 2.1) d in SIMV group,with no statistically differences between the two groups (P ＞ 0.05).Conclusion PAV is very effective in treating the neonatal respiratory failure and worth spreading.

BACKGROUND: More and more patients with periodontal disease require orthodontic treatments. Thus, the remodeling process and its mechanism of inflammatory periodontal tissues become a hot point during orthodontic tooth movement.OBJECTIVE: To observe the remodeling of inflammatory periodontal tissues during orthodontic tooth movement.METHODS: A total of 50 Sprague Dawley rats were randomly divided into the control and periodontitis groups. In the periodontitis group, rats were established periodontitis models. After that, all rats were prepared for orthodontic tooth movement models. The remodeling of periodontal tissues was observed by hematoxylin-eosin staining at 1, 3, 5, 7 and 14 days after orthodontic tooth movement.RESULTS AND CONCLUSION: The movement distance of the periodontitis group was greater than that of the control group. At 0-7 days after orthodontic force application, there was obviously bone resorption at the pressure side and the bone formation was inhibited at the tension side; at 14 days after force application, the bone resorption was diminished, associated with large numbers of multinucleated osteoclasts at the pressure sides in both groups. The findings showed that rats with periodontitis suffered more periodontal traumatism during orthodontic tooth movement, thus, treatment should be delayed until the inflammatory signs were controlled and the local inflammatory was eliminated.

Deproteinized calf blood injection is composed of small protein-free molecules extracted from fresh calf blood. The pre-vious studies showed that it can improve metabolic balance by increasing glucose and oxygen uptake to enhance energy metabolism. In recent years, due to the expanding clinical applications of deproteinized calf blood injection, new observation results and ideas contin-ued to emerge. However, the reports of adverse reactions and excessive applications were also gradually increased. In order to provide reference for the promotion of reasonable clinical application, the paper reviewed the latest development in the studies on the clinical application of deproteinized calf blood injection.
