Objective To explore the effect of low-dose imfepristone on the endometrial simple hyperplasia.Methods Study group were randomly divided into two groups.43 cases in group mifepristone,43 cases in group norethindrone and control group were 20 cases.The endometrial histopathology and the contents of ER and PR were examined before and after the treatment.The changes of endometrial thickness and hemoglobin were detected,too.Results The endometria were all simple hyperplasia before taking the medicine and turned to proliferative stage after taking mifepristone and norethindrone.There were significant difference compared with taking the medicine before(P＜0.05).However,there were no statistical difference between two groups after taking the medicine(P＞0.05).The endometrial ER and PR were significantly depressed after taking the medicine compared with before in study group(P＜0.05).There were no significant difference between control group and group mifepristone after taking mifepristone(P＞0.05).But there were significant difference between controI group and group norethindrone after taking norethindrone(P＜0.05).The endometrum were significant turned thin and the contents of hemoglobin were significantly risen up after taking the medicine in study group(P＜0.05).But the contents of hemoglobin were significantly risen up after taking the medicine in group mifepristone compared with group norethindrone(P＜0.05).Conclusions Low-dose mifepristone can inhibit endometrial simple hyperplasia and turn the endometria from simple hyperplasia to proliferative stage.Low-dose mifepristone may adjust the endometrial ER and PR for inhibitting endometrial hyperplasia and make the expression of endometrial ER and PR decrease.But the contents of ER and PR were more close to normal after taking mifepristone.Low-dose mifepristone can attenuate the endometria and regain the hemoglobin fast.There are seldom side-effects after taking low-dose mifepristone.

Objective To observe the performance of two-dimensional echocardiography and CDFI of metastatic cervical lymph nodes in nasopharyngeal carcinoma before and after induction chemotherapy,and to predict the short-term effect of the lymph nodes after sequential chemoradiotherapy.Methods Forty patients with sixty-five metastatic cervical lymph nodes which were confirmed as nasopharyngeal carcinoma by biopsy and CT were studied.CDFI was used to observe its size,the peak systolic velocity (PSV),resistivity index (RI),and record its classification of blood flow before and after induction chemotherapy,after radiotherapy 1 to 2 months for ultrasound,respectively,and the measured values and short-term effect in cervical lymph node metastasized were compared.Results According to the changes of blood supply after induction chemotherapy,lymph nodes were divided into three groups,the group of improve blood supply was given priority (55 ％),blood supply to reduce and no change groups were 23 ％,22％,respectively.After induction chemotherapy and sequential radiotherapy,all lymph nodes were narrow,regression rate after induction chemotherapy in blood supply to reduce,improve and no change groups were 52％,36％,25％,respectively,the regression rates of sequential chemoradiotherapy were 90％,81％,70％,respectively,among three groups are in degressive tendency,differences were significant (P ＜ 0.05).The blood supply changes after induction chemotherapy related well with the regression rate of chemotherapy(r =0.572,P =0.000) and sequential radiotherapy(r =0.553,P =0.000).The regression rate of chemotherapy related well with the regression rate of sequential chemoradiotherapy(r =0.621,P =0.000).After chemotherapy three groups of lymph node RI decreased,the difference was significant compared with that before treatment (P ＜ 0.05).After chemotherapy the groups to reduce and improve of PSV had significant differences compare with that before treatment (P ＜ 0.05),the group of blood supply no change of PSV had no significant difference (P ＞ 0.05).Conclusion Application of CDFI can clearly and accurately observe changes of metastatic cervical lymph nodes from nasopharyngeal carcinoma before and after induction chemotherapy,and the changes of blood supply and size after induction chemotherapy can predict the short-term effect after chemoradiotherapy.

Objective To study the salt intake of patients undergoing maintenance hemodialysis and explore their knowledge and behaviour. Methods The patients undergoing maintenance hemodialysis were offered salt spoon and soy sauce cup. Their diaries on home meals for 3 consecutive days were collected to calculate their salt intake. Meanwhile, a one to one interview was done to evaluate the accuracy of patient′s diet diary and the knowledge and behavior of low salt diet and find out related factors of salt intake. Results The average salt intake was (6.49 ± 1.64)g/d. The average composition rate in the low salt diet knowledge in low salt diet behavior was 51.00% and 47.00% respectively. Age and education level were the influencing factors of salt intake. Conclusions The average salt intake is much higher than the standard for the patients undergoing maintenance hemodialysis. Their low salt diet knowledge is in the middle level and their low salt diet behavior is in the middle or lower level. The related factors include age and education among patients undergoing maintenance hemodialysis.

Objective:To screen for simulation peptide binding specifically to the first and the second extra-cellular domain of CC chemokine receptor 5(CCR5),and to observe their therapeutic effect on mice with experimental autoimmune encephalomyelitis(EAE).Methods:Phage display peptide library was used to screen for peptide sequence binding specifically to CCR5;ELISA was used to identify its binding activity and analyze its DNA sequence.The simulation peptide was synthesized and was injected into abdominal cavity of the EAE mice.Spinal cord tissues were obtained and the pathologic changes were studied by H-E staining in EAE control group and simulation peptide group.Results:Twenty phage clones were randomly chosen for identification and ELISA showed that there were eighteen clones had a strong binding activity with CCR5.The positive clones were sequenced and four peptides of high frequency were obtained:STFTTTL,TPIPQLL,SLPLPKP,and QTSSAAL.Mean clinical score of mice in the EAE model group was 3 and that of the simulation peptide group was 1.H-E staining found that the spinal cord tissues in EAE model group had great number of inflammatory cells and evident demyelination changes;the simulation peptide group had less inflammatory cells and no demyelination changes.The four short peptides had an effect of suppressing and delaying the development of EAE,with the average inhibition rate being 43%(P

Objective To develop a new single-tube polymerase chain reaction amplification (ST Amp) protocol for the efficient sequencing-based typing (SBT) of human leukocyte antigen DRB1(HLA-DRB1).Methods A set of 7 group-specific exonic 5′ amplification primers and a single generic 3′ primer were included together in a single PCR mix to facilitate a single PCR amplification per sample for HLA-DRB1 typing.Results All samples were successfully typed, the typing result was accurate and repeatable.Conclusion ST Amp technique has resulted in the ability to perform high-resolution, high-specificity and high-throughput HLA-DRB1 typing by DNA sequencing.

Objective To investigate the effects of environmental enrichment (EE) on the neurological functions in patients with stroke. Methods From May, 2013 to November, 2015, 76 patients with stroke were selected and randomly divided into control group (n=39) and EE group (n=37). Both groups received routine therapy and the EE group received EE in addition. They were assessed with simplified Fugl-Meyer Assessment (FMA), Montreal Cognitive Assessment (MoCA) and modified Barthel Index (MBI) before and after treatment. Re-sults The scores of FMA, MoCA and MBI increased in both groups after treatment (t>2.339, P<0.05), and the scores of MoCA and MBI in-creased more in the EE group than in the control group (t>2.187, P<0.05). Conclusion EE could promote the recovery of cognitive function and activities of daily living in patients with stroke.

Objective To investigate the effects of endothelin-1 on the proliferation of HCT-116 cells. Methods The expression of endothelin-1 and endothelin receptors A and B in the HCT-116 cells was detected by RT-PCR and immunohistochemistry method.The effects of endothelin-1 at different concentrations and action time points on HCT-116 cells were measured by MTT assay and were analyzed by variance analysis.Results The expression of endothelin-1 and endothelin receptors A and B at the gene and protein levels in HCT-116 cells was detected.Endothelin-1 had significant effects on the proliferation of HCT-116 cells.The proliferation peak of HCT-116 cells was reached when the concentration of endothelin-1 was 1×10-7mol/L and the action time was 48 hours.Conclusions Endothelin-1 promotes proliferation of HCT-116 cells in a dose-and time-dependent manner,and the process is mediated by endothelin receptors.

Objective To observe the changes of MMP-1 and TIMP-1 expression in the pathological scar tissue after scar-skin replantation and to explore the mechanism of treating pathological scars with scar-skin replantation through a rabbit ear model.Methods Rabbit ears were used to establish the hypertrophic scar animal model in this study.Specimens were taken for three times:normal skin,hypertrophic scar and scar-skin replantion separately.We then performed HE staining,Masson staining and immunohistochemical staining to observe the expression of MMP-1 and TIMP-1 in these three groups of specimens.Results The expression of both MMP-1 and TIMP-1 significantly increased in the hypertrophic scar tissue after scar-skin replantation compared with the control group (P＜0.01).The expression of MMP-1 increased more significantly than that of TIMP-1 (P＜0.01).Conclusions The mechanism of scar-skin replantation's effect in the treatment for hypertrophic scar is relevant to the imbalance in the interaction between MMP-1 and TIMP-1 in the scar tissue.

Objective There is a huge demand for rehabilitative services in Chongqing whereas detailed information regarding local clinical services and rehabilitative professionals are unknown. Therefore, a cross-sectional survey was conducted to generate a profile of current rehabilitative status in Chongqing for reference of relevant local parties and peers in other provinces of China to create a larger picture of rehabil-itation in China. Methods The survey began in early January of 2015 and ended on October 20th of 2015. With two categories of information, including background of rehabilitation professionals and rehabilitative clinical services, the self-made questionnaire was sent via email to rehabilitation therapists working in local clinical settings which fulfilled the inclusion criteria. The reminder was sent once a month to those who did not yet replied. The software SPSS 20.0 was used to analyze the data descriptively. Results 7 out of 13 in-volved clinical settings responded with an overall response rate of 53.8%. 98 out of 122 copies were adopted based on filling requirement. The result revealed 68.4%(n=67) of the participants were junior practitioners, 57.1%(n=56) of them had less than 5 years experience and 45.9%(n=45) were holding a diploma with little research experience. As for clinical services, assessment of ROM (94.9%, n=93) and manual muscle testing (94.9%, n=93) were mostly used. The physical therapy service was more prevalent than occupational therapy services. The clinical field mostly involved was adult rehabilitation (77.6%, n=76). Bedside training in the acute phase (81.6%, n=80) and one-to-one treatment (92.9%, n=91) was the most commonly seen mode of service in the departments. Conclusion The local rehabilitative professionals were featured by their young age with comparatively low educational level, qualification and weak research skills. The clinical services they provided were yet quite basic and simple. Thus, a set of policies regarding education and profession in rehabilitation therapy should be facilitated instantly and it also calls for the establishment of local academic society for rehabilitation therapists, thus promoting an all-round development of rehabilitative profession.
