Random clustering was conducted among a total of 1068 residents aged 18 years or older at a certain Shanghai community.And they completed a questionnaire survey.Logistic data processing and model building were performed.The respondents were willing to go to a community health center for the following reasons:close proximity (88.4％),excellent service attitudes (40.4％) and low drug prices (37.8％).No statistically significant differences existed in terms of first choices of community health service,occupation,monthly income and-walking distance (P ＞ 0.05).However,statistically significant differences existed in education level,age and chronic diseases (P ＜ 0.05).

Objective To observe the retinal toxicity of repeated intravitreal injection with bevacizumab(Avastin)in diabetic rats.Methods Forty male Sprague Dawley(SD)rats were randomly divided into normal group(Group A,10 rats)and diabetes mellitus group(30 rats).The rats in diabetes mellitus group were induced with streptozotocin injection for diabetic retinopathy model.And then randomly divided into diabetic retinopathy(DR)group(Group B,10 rats),the rats were not intervened;the left eyes of the other 20 rats were intravitreal injected with bevaeizumab 3 μ1(25 mg/m1)for 3 times as experimental group(Group C);the right eyes of the 20 rats were not intervened as experimental control group(Group D),20 days after last intravitreal injection,retinal function was measured by Flicker Electroretinogram (F-ERG);retinal vascular pattern was determined by fluorescence microscopy of ethidium bromide(EB)stained retinal flat mounts;retinal morphological changes were determined by light microscope on hematoxylin-eosin (HE) stained sections;Thy-1 and VEGF expression was measured by immunohistochemistry staining.Results F-ERG showed that-the differences of a-and b-waves-the b-wave amplitude and the Ops-wave amplitude in the implicit time between group A,B,C and D were significant (F=33.165,36.162,19.955,23.243;P=0.000);the differences of a-wave amplitude between group A,B,C and D was not significant(F=0.097,P=0v961).Retinal blood vessel pattern was normalin Group A;retinal vascular vessels were tortuous and irregularly expanded in Group B:retinal vascular vessels of Group C were regular and thinner than Group A;microaneurysm were showed in Group D.Light microscope displayed that the layers of the rat retina of Group A were regular,the retinal architectures of Group B were irregular,the retinal layers were regular in Group C,the retinal layers were irregular in Group D.Immunohistochemistry staining discovered that Thy-1 and VEGF were mainly expressed in ganglion cell layer(GCL).Conclusion Repeated intravitreal injection of bevacizumab iS toxic tO retina of diabetes mellitus rats.

Objective To observe the effect of reteplase on the thromboelastogram tracing of patients experiencing acute is-chemic stroke(AIS).Methods Selected 43 AIS inpatients in the Third People’s Hospital of Liaocheng from October,2013 to August,2015,who received reteplase less than 4.5 hours after the onset of syndrome of AIS.Blood samples were obtained before reteplase administration and at 0.5,1,2 and 4 hours after reteplase administration and measured by thromboelastogra-phy.Results The parameters R,K,Angle and MA of the thromboelastogram had changed after beginning administration of reteplase.The R value at 0.5 h after thrombolysis was significantly higher than that before thrombliysis,however,the R Value at 1h after thrombolysis was the most highest,and the K value.At 0.5 h after thrombolysis was the highest.At 0.5 h after thrombolysis MA and Angle values were the lowest,the differences were statistically significant (P<0.001).Conclu-sion The study suggests that the thromboelastogram is an useful tool for determining changes in the coagulation system of patients receiving reteplase.

The inhibitory effect of Actinidia chinensis Planch(ACP) juice on the endogenous formation of N-nitroso compounds (NOC) in the subjects from a high-risk area for gastric cancer were observed. Total concentration of volatile N-nitrosamines(VNA)in fasting gastric juice and 24-h urinary excretion of N-nitrosoproline (NPRO) were used as indices of endogenous exposure. After iagestion of 30 ml ACP juice the average total VNA concentration was significantly decreased from 2.08?1.06?g/L to 0.42?0.43?g/L (p

ObjectiveTo explore ultrasonographic featurs of nuchal skin of normal fetus in its thickness and changes.MethodsThe thickness of nuchal skin of 900 normal fetal was measured by abdominal ultrasound with 7.5 MHz probe.ResultsThe nuchal skin only displayed whole layer before pregnant 27 weeks. After pregnant 27 weeks, the derma and subderma layer was distinguishable, the whole thickness of nuchal skin was ( 1.18 ? 0.05 )mm (10 weeks) to ( 6.01 ? 0.46 )mm (40 weeks) in normal fetus. All layers of nuchal skin were increased proportionally with gestation [r= 0.973 (whole layer), P 0.05 ).Conclusions The abnomal chromosome of fetus could be sifted by the thickness of nuchal skin and the character of sonographic image. It′s a useful diagnostic method for eugenics.

Ki-67 is a common proliferation marker,especially used to reflect the proliferation activity of malignancy cells.Recently this marker has been widely studied among early breast cancer patients,However,to date,whether include Ki67 in the list of required routine biological markers there is still a hot argument.This review mainly explores and summarizes the prognostic and predictive role of this marker in breast cancer,the clinical value of the combination of Ki-67 and other makers,and the problems lie in the application of Ki-67 in clinical practice.

Papillary thyroid cancer (PTC) is the most common malignant neoplasm originating from the thyroid gland and has an excellent prognosis.But cervical lymph node metastases are common and the most common sites of metastases are the central lymph nodes of the neck (level Ⅵ).While therapeutic central lymph node dissection for involved lymph nodes is needed in our nation and others,the controversial topic is whether routine prophylactic central lymph node dissection in patients without evidence of lymph node metastasis should be performed in patients with PTC.The author reviewed the research development of prophylactic central lymph node dissection for papillary thyroid cancer in the article.

Non-small cell lung cancer has a poor prognosis. Many patients who were proved to have none lymph node metastasis still relapse after operation. It may be caused by micrometastases which can′t be detected by conventional pathologic technique. Recently immunocytochemistry and moleculer methods are used to detect micrometastases in the peripheral blood, bone marrow or lymph node near the tumor. But the standard and reliable methods need to be developed and the clinical significance of micrometastases need to be discussed.
