Objective To investigate the Diane -35, femonston of missed abortion endometrial repair. Methods According to the different treatment methods will be January 2015 to March 2017 in the first affiliated hospital of Tianjin university of traditional Chinese medicine 60 cases of patients with missed abortion groups: control group with -35 treatment, the observation group with femonston treatment; detailed observation of the two groups patients with various treatment index (bleeding time, bleeding volume, postoperative day 21 endometrial thickness, the tide time, the tide period), the occurrence of adverse reactions, and the related data were analyzed. Results Femonston (observation group) in treatment of patients with missed abortion is better than - 35 (control group) treatment, patients with various treatment index than the control group, the incidence rate of adverse reaction was lower than the control group, the difference was statistically significant (P<0.05). Conclusion Femonston can effectively repair the endometrium of patients with missed abortion, and shorten the time with the tide, the tide of stable period it is worthy of widely used intervention in patients with missed abortion.

Tumor is one of the most serious problems threatening people's life in the 21 st century. Antitumor vaccine becomes a hot research spot of tumor therapy for low toxicity, specificity and durability. Efficient recognization and presentation of tumor antigen contribute to the foundation of an powerful anti-tumor immunologic response. Along with the deepen apprehension of the immunity mechanism and high development of the biochemical technology, a great number of new vaccines emerge and show us some favors. And DNA vaccine and DC vaccine attract most sights for their advantage in antigens expression and presentation.They become the strong weapon for tumor immunity therapy. This is a review about the mechanism, development and current problem of DNA vaccine and DC vaccine.

Objective To investigate the effect of Toutongning capsule for treatment of headache with stroke-associated risk fac-tors .Methods 60 cases of headache patients with stroke-associated risk factors were selected and divided into the treatment group and the control group ,30 cases in each group .The treatment group were given conventional therapy plus Toutongning capsule while the control group were given conventional therapy only .Results After 4 weeks ,the remission rate of treatment group was 93% and that of the control group was 63% .The attack frequency ,duration and degree between the two groups showed statistically signifi-cant difference(P<0 .05) .Conclusion Additional Toutongning capsule has a better effect for treatment of headache with stroke-as-sociated risk factors.

Objective To investigate the correlation of long term aspirin treatment and cerebral microbleeds(CMBs)incidence in non-hypertensive patients.Methods 56 non-hypertensive patients (the average age of 64.88±6.99)with long term aspirin adminis-tration (100 mg/d)were enrolled in the study from 2005 to 2010 in our hospital,with follow up to compare CMBs 5-10 years later. All patients underwent T2 WI,T1 WI,diffusion-weighted imaging (DWI)and susceptibility weighted imaging (SWI).The CMBs lesions were defined by senior radiologists.Patients’age,gender,total cholesterol level,aspirin,CMBs and CMBs location were taken into account in data analysis.Results CMBs incidence was 14.3% in all participants,lesions were located mostly in lobes.Aged,male and low total cholesterol level were the risk factors of CMBs (P<0.05).Patients with CMBs were more likely to suffer from acute cere-bral infarction (P<0.05).Two of 56 patients with new CMBs lesions located in lobar and mixed location respectively only.Conclusion Long term aspirin administration does not increase the risk of CMBs in non-hypertensive patients(P>0.05),the potential adverse effect of aspirin needs further investigation.

The functions of the top 15 medical APP were compared.Their major functions of medical advice, information service and medical service were analyzed.The key functions of mobile medical APP used in China were described with suggestions for their development.

Objective To compare the differences in histological morphology and hemodynamics between benign and malignant tumor, as well as differences between the different perfusional regions in tumors of the same type. Methods Thirty cases with malignant breast carcinoma and 30 cases with fibroadenoma were inspected by contrast enhanced ultrasound with time-intensity quantitive analysis. Perfusion index like peak intensity(PI), area under the curve(AUC), time to peak(TTP) and wash-out time (WOT) were collected both inside and at the margin of focus. The ultrastructures of new microvessesl were observed routinely with microscopy and transmission electron microscopy. Results The curve of malignant tumor group was characterized as ascend rapidly and drop slowly while the benign group presented as ascend slowly and drop rapidly. The AUC and WOT of malignant tumor group were significantly higher than that of benign group,while the PI and TTP had no statistical difference. In malignant tumor group,PI, AUC and WOT of the margin of focus were significantly higher than that of inside region of focus,while TTP was the opposite. However,there was no statistical differences between the perfusion parameter inside and outside of focus in benign group. The ultrastructures of newly built blood vessels in malignant group had strong ability to split,which was different from normal endothelium cells but was similar to other tumor foci. The margin of foci were characterized with dilatating and distorting vessels,and the center of the foci were occupied by narrow,occlusive new vessels and contracted anamorphic endothelium cells and pericytes. Rich microvessel areas located in the margin of foci. Conclusions The perfusion pattern,modality of time-intensity curve, mean perfusion parameter and variance of regional perfusion parameters are valuable diagnostic basis in discriminating benign and malignant breast tumor. The density,modality,distribution,structure and function of new microvessels in tumor focus are also keystone factors when tumors are assessed by means of imaging.

Objective To understand the grade point average (GPA) of degree courses and its in-fluence factors in Master postgraduates in China. Method A cross-sectional study was carried out to collect the data on GPA and the student information in the management system of postgraduates who graduated from Graduate School of Public Health from 2013 to 2015. SPSS 20.0 was used to describe the basic situa-tion, and the data were analyzed by one-way ANOVA, Pearson correlation analysis and multivariate analysis of variance. Results During 3-year, totally 213 Master students were graduated with the average GPA of (3.19±0.30). The female had higher GPA than the male subjects [(3.24±0.29) vs. (3.05±0.29), F=17.11, P=0.000], those enrolled by the recommendation than those enrolled by the graduate entry examinations [(3.36±0.25) vs. (3.11±0.28), F=39.36, P=0.000], those graduated from the university of 985 were better than the graduate students from other universities [(3.30±0.29) vs. (3.11±0.28), F=22.14, P=0.000], those with the academic degree than those with the professional degree [(3.31±0.25) vs. (2.99±0.27), F=72.38, P=0.000], and there was a negative relationship between the total credits and GPA of degree courses (r=-0.48, P=0.000). Further, sex, enrollment way, undergraduate university, and total credits of degree courses were independent influence factors under multivariate analysis of variance (all P<0.05). Conclusion These master graduates in medicine have better GPA of degree courses and it can be statistically related to sex, enrollment way, undergraduate university, and total credits of degree courses. Some measures should be developed to enroll more students from better university, improve the master programs, and raise the quality of graduate education management.

Objective To study the imaging characters and diagnostic value of spondylolysis and spondylolisthesis by usingthree-dimensional reconstruction of spiral CT. Methods 37 patients with spondylolysis were scanned by spiral CT.Various reconstruction methods were applied on the data acquired. Results The axial CT scans achieved good resolution on showing hyperostosis,fibrous callus and pathological changes of spinal disc.Spondylolysis was all displayed in the MPR/MIP of sagittal,reverse gantry angle and CPR.MIP,MPRand CPR could provide better resolution in display of spondylolysis than SSD did,while SSD was better in display of hyperostosis andspondylolisthesis. Conclusion The three-dimensional reconstruction of spiral CT is a good method for the radiographic evaluation ofspondylolysis and its relative changes.This technique can provide reliable informations for planning clinical therapy.
