Objective To detect the binding ability of the molecular probe of neuropilin-1( NRP-1) to mouse ectopic glioma by magnetic resonance imaging ( MRI) . Methods Glioma model mice were pre-pared by glioma tissue transplantation.Thirty tumor bearing mice were randomly selected for tissue anatomy(n=12) and other 18 mice were randomly divided into 3 groups:the control group ( group A) ,the probe con-trol group (group B) and the probe group (group C),which were given 20 μl saline,20 μl USPIO-PEG, 20μl USPIO-PEG-tLyP-1 through the tail vein of the mice respectively.And at 0h,6h,12h,24h after admin-istration,T2WI and T2MAPPING sequences were detected by MRI. Then the tumor bearing mice were killed immediately and the glioma tissue was used to detect the iron content by Prussian blue staining to detect the binding ability of the glioma tissue with the new molecular probe. The biological toxicity of the new molecular probe was detected by pathological staining. Results The expression of NRP-1 in glioma tissues was signifi-cantly higher than that in the liver,kidney and brain(P<0.05).The 24h relaxation time ((14.19±0.87)ms) of the glioma tissue in the C group was significantly lower than that in the B group ((25.94±0.77)ms) (P<0.05) ,and the blue staining particles in the C group were more than those in the B group(P<0.05) . Conclu-sion In the animal experiment,the molecular probe with NRP-1 as the target has obvious targeting effect and good biocompatibility,which provides a clinical basis of glioma for further clinical diagnosis.

Objective: To investigate the expression of HSPC238 in cervical intraepithelial neoplasia and cervical cancer.Methods:We collected 76 cases of cervical cancer,105 cases of CIN and 28 cases of normal cervical epithelial.Then we inves-tigated the expression of HSPC238 by using immunohistochemistry and compared the significant differences between them.Results:There was no significant difference in the expression of HSPC238 between the cervical cancer and normal cervical epithelial ( Z=-0.242,P>0.05).However,there was significant difference between the cervical intraepithelial neoplasia and normal cervical epithelial (χ2=19.159,P<0.01) and the expression of HSPC238 was correlated with the grades of CIN.The expression of HSPC238 decreased when the grade of CIN was increasing.( rs=-0.327,P<0.01 ).Conclusion:The low expression of HSPC238 might be correlated with the development of cervical neoplasia.

BACKGROUND:A few of studies have showed similar efficacy and safety between domestic clopidogrel (Talcom?) and imported clopidogrel (Plavix?) in patients after percutaneous coronary intervention, but there is lack of large-scale, large sample, and prospective clinical comparative study in China.
OBJECTIVE:To compare the efficacy and safety of Talcom?and Plavix?on percutaneous coronary intervention.
METHODS:Total y 1 798 patients with Coronary atherosclerotic heart disease who received percutaneous coronary interventions were divided to two groups:Talcom?group (n=1 104) and Plavix?group (n=694). 300 mg clopidogrel was administrated oral y before percutaneous coronary intervention fol owed by 75 mg/d clopidogrel sequential y for 1 year. Al the patients were fol owed for 3-28 months to observe the incidence rate of stent thrombosis at acute, subacute, late, and very late stage, major adverse cardiac events of combination end point (including myocardial infarction, cardiac death, and stroke), and correlated adverse reactions, such as bleeding.
RESULTS AND CONCLUSION:There were no significant differences in the incidence of stent thrombosis, target vessel revascularization, cardiac death, bleeding, major bleeding and major adverse cardiac events of combination end point between Talcom?group and Plavix?group. In addition, event-free survival also showed no difference between the two groups. After treatment, white blood cellcount, erythrocyte count, hemoglobin, hematocrit, platelet count were significantly decreased in both the two groups (P<0.05). Hemoglobin level in the Talcom?group was fewer than that in the Plavix?group (P<0.05). The results suggest that effects and safety of Talcom?are similar to those of Plavix?for percutaneous coronary interventions.

Objective To observe the expression of neuropilin-1 (NRP-1) in glioma cells of different grades,and evaluate the application value of a novel molecular probe(USPIO-PEG-tLyP-1)in the grading diagnosis of heterotopic glioma in nude mice by magnetic resonance imaging (MRI).Methods Expression levels of NRP-1 in glioma cell lines of different grades were detected by Western-Blot.USPIO-PEG-tLyP-1 was synthesized by carbon diimine method.The U87-MG tumor-bearing mice model (U87-MG group) and CHG-5 tumor-bearing mice model(CHG-5 group) were established with 10 mice in each group.Six tumorbearing mice with a tumor volume about 0.6 cm3 were selected from each group,and they were given with 2mg/kg molecular probes via tail vein respectively and was detected by MRI at 0 h,6 h,12 h and 24 h,then R2 values were calculated.After the imaging,tumor-bearing mice were sacrificed,and tumor tissue sections were made.The iron particles in the sections was detected by Prussian blue staining.The binding ability of molecular probes and tumor tissues in the two groups was compared.Results The expression of NRP-1 in U87-MG and CHG-5 cell lines was significantly higher than that in HA.In addition,the expression of NRP-1 in U87-MG was higher than that in CHG-5 cell(P＜0.01).MRI results showed that R2 values of tumor tissues in the two groups were compared,and the difference was not statistically significant before the injection of molecular probe(U87-MG group(10.35±0.52)vs CHG-5 group(9.86±0.43),t=1.779,P=0.106).The R2 value of tumor tissue in the U87-MG group was higher than that in the CHG-5 group after the injection of molecular probe (6 h:U87-MG group (11.63±0.85)vs CHG-5 group (10.51 ±0.49),t=2.796,P=0.019;12h:U87-MG group(14.23±0.68)vs CHG-5 group(12.29±0.28),t=6.462,P=0.000;24 h:U87-MG group (13.36±0.92) vs CHG-5 group(11.32±0.64),t=4.459,P=0.001).The results of Prussian blue staining showed that there were significantly more blue staining particles in tumor tissues of the U87-MG group than that of the CHG-5 group,and the difference was statistically significant(P＜0.01).Conclusion The NRP-1 targeted molecular probe can be used for grading diagnosis of high and low grade heterotopic brain glioma in nude mice.

Objective:To analyze the influenza vaccination status of chronic disease management patients in Qingpu district of Shanghai and the vaccination characteristics of different characteristic populations, so as to provide scientific basis for improving the influenza vaccination rate of chronic disease patients in the community.Methods:By comparing the data of Shanghai chronic disease management information system, immunization planning information system and medical association platform, 89 453 subjects who met the inclusion and exclusion criteria in Qingpu district were selected as the research objects. The vaccination coverage rate of the study subjects was calculated according to gender, age group, urban and rural distribution, occupation, chronic disease type and quantity, and the vaccination coverage rate of different subgroups was compared to analyze the influencing factors of vaccination coverage rate.Results:Most of the 89 453 patients with chronic diseases were 60 years old and above (71.93%). Patients with hypertension, diabetes, chronic obstructive pulmoriary disease (COPD) and three chronic diseases accounted for 87.12%, 28.67%, 8.71% and 1.83%, respectively. Influenza vaccination coverage in the 2016/2017 flu season was low, at 0.32%. Influenza vaccination coverage rate of women (0.37%) was higher than that of men (0.27%), which was 1.41 times respectively(95% CI: 1.16, 1.72) that of men patients. The coverage rate of influenza vaccination for the 70-79 year-old group was the highest (0.74%), which was 1.74 times respectively(95% CI: 1.39, 2.19) that of 60-69 year-old patients. The vaccination coverage rate of government departments and institutions was the highest (1.14%), which was 12.58 times respectively(95% CI: 4.52, 34.99) that of retirees. The vaccination rate of COPD patients (3.68%) was 2.50 times (95% CI: 1.66, 3.77) higher than that of patients without COPD.Conclusions:Influenza vaccination rate for chronic disease management patients in Qingpu district of Shanghai is low. Gender, occupation, age and types of chronic diseases are the influencing factors. Patients with chronic disease management should be included in the priority vaccination targets for influenza vaccines, and vaccination intervention for occupational chronic diseases such as non-retired agriculture and forestry patients, especially male patients, should be strengthened to improve influenza vaccination coverage rate.
