Objective:To analyze the cognition and willingness of family physicians on contracted service, and to explore the implementation obstacles and feasible strategies of implementing contracted service of family physicians from the perspective of suppliers.Methods:From July to October 2020, 850 family physicians in community health service centers or township health centers in three cities of Shandong Province were investigated by questionnaire survey and key person interview. Descriptive analysis and binary logistic regression model were used to analyze the willingness of family physicians to provide contracted service. Through questionnaire survey and key person interview, the implementation obstacles and service optimization strategies of family physicians were discussed.Results:791 valid questionnaires were obtained, of which 688(87.0%) approved the implementation of family physician contract service, and 679(85.8%) expressed willingness to provide family physician contract service. Marital status, recognition of service policy, satisfaction of service operation effect, optimistic degree of service development prospect and residents′ first choice of illness were the factors influencing family physician′s service willingness.Conclusions:We should effectively improve the family doctor′s service intention and promote the efficient and orderly implementation of family doctor′s contract service policy through enriching policy supporting measures, innovating the application of " Internet plus" , increasing personnel training, optimizing performance appraisal work and creating favorable public opinion environment.

Objective The aim of this study was to evaluate the glioma using the variety of functional magnetic resonance imaging( fMRI) ,and to perform a more accurate preoperative diagnosis of gliomas. Methods Thirty - five patients with gliomas confirmed by pathology were examined by magnetic resonance imaging (MRI)and functional MRI. Rapid diffusion coefficient(D?),Slow diffusion coefficient(D),perfusion fraction ( f) and distribution diffusion coefficient ( DDC ) in the intravoxel incoherent motion diffusion weighted imaging (IVIM-DWI) were analyzed statistically. Results The mean values of D?,D,f and DDC in the IVIM se-quence of the patients with high-grade of gliomas were statistically significant when compared to the IVIM values of the contralateral normal brain tissues(P<0. 05). Conclusion A variety of magnetic resonance functional im-aging sequences are used to analyze gliomas,which can avoid tumor heterogeneity and improve the recognition a-bility and accuracy of magnetic resonance imaging in high grade gliomas.

Objective To study the role of D‐lactate gradient across the lung in the rapid diagnosis of pneumonia and evalua‐tion of therapeutic efficacy .Methods Patients were divided into pneumonia group (n=46) and non‐pneumonia group (n=28) in ICU .D‐lactate gradient across the lung were calculated by the difference between arterial and mixed‐venous D‐lactate concentrations before the treatment ,after 3 and 7 days of treatment .Serum procalcitonin (PCT) ,Oxygenation index ,the lung injury score (LIS) and clinical pulmonary infection score(CPIS) were recorded at the same time .Results The mean D‐lactate gradient across the lung in pneumonia group was significantly higher than that in non‐pneumonia group[(163 .84 ± 10 .72) ng/mL vs .(30 .33 ± 7 .25) ng/mL ,P<0 .01) ]before treatment .Using a cut‐off value of 106 .11 ng/mL ,D‐lactate gradient across the lung′s sensitivity for di‐agnosis pneumonia was 90 .7% and its′specificity was 75 .5% .D‐lactate gradient across the lung correlated with LIS (r= 0 .554 , P<0 .01) and CPIS(r=0 .543 ,P<0 .01) .Conclusion D‐lactate gradient across the lung correlates with lung injury and pulmonary infection positively and may be a potential biomarker for rapid diagnosis of pneumonia .

Objective To investigate the impact of Ang-1 on the septic mice′pulmonary vascular endothelial barrier function and VE-cadherin and its mechanism. Methods 80 BALB/c mice were randomly divided into NS, LPS, LPS+Ang-1, LPS+Ang-1+ Ly and Ang-1 groups (n = 16). Measure VE-cadherin, Ang-2 levels in plasma and lung permeability index (LPI).Test the total VE-cadherin of lung and the phosphorylation of VE-cadherin expression. Results Plasma Ang-2 was higher compared with NS group(P<0.01) except Ang-1 group. In LPS+Ang-1 group and LPS+Ang-1+Ly group, plasma Ang-2 was lower compared with LPS group (P <0.05). In LPS+Ang-1+Ly group, plasma Ang-2 was higher compared with LPS+Ang-1 group (P<0.01). LPI, plasma VE-cadherin and lung phosphorylation of VE-cadherin were the same with the trends of the plasma Ang-2 , but the lung total VE-cadherin showed the opposite tendency. Conclusion Through the PI3K/Akt signal transduction pathway , Ang-1 may regulate septic mice′VE-cadherin , hence the pulmonary vascular endothelial barrier function improved.

Regulatory T cells (Treg),a group of negative regulatory cells,have four subsets:CD4+Treg,CD8 + Treg,NKT Treg and DN Treg cells.They play an essential role in the inhibitive immune-regulation and might be the key factors of neoplasms immune escape.These mechanisms include inhibiting the effector cell function by inhibitory cytokines,killing effector cells by granzyme and perforin,competition and inhibiting IL-2,and affecting Treg differentiation and proliferation by regulating the function of CTLA-4,etc.Tumor immunotherapies targeting Treg and related immunosuppressive factors,such as remove Treg or controling the numbers and functions,enhances the immune response against tumors,which might offer a new method of tumor immunotherapy.

Objective To assess the effect of aspirin for the chemoprevention of colorectal adenomas by meta analysis of the published literature.Methods Cochrane strategy in combination with manual search was used to identify previously published randomized controlled trials by searching PubMed,EMBase,Cochrane Library,China Journal Full-text Database(CNKI),Chinese Scientific Journal Full-text Database (CSJD) and Chinese Biomedical Literature Database (CBM).Results Six randomized controlled trials involving a total of 2 858 patients were studied.Of the six trials,two trials were performed in China,four trials were in the Europe and the United States.Some sufficient evidence were found to support that aspirin could prevent of colorectal adenomas compared with placebo group ( P =0.003,RR =0.66,95% CI:0.50-0.86).No adaquate evidence supported the role of aspirin in the prevention of development of colorectal cancer ( P =0.29,RR =0.65,95% CI:0.30-1.44).High-dose aspirin ( P =0.10,RR =0.85,95% CI:0.71-1.30 ) and low-dose aspirin could prevent colorectal adenomas compared with placebo group( P =0.02,RR =0.57,95% CI:0.36-0.90),and a dose-dependent associtation was found.The risk of stroke was higher in any dose of aspirin compared with placebo group ( P =0.04),and the risks of adverse events had no significant differences in all groups.Conclusion Aspirin might prevent the development of colorectal adenomas in individuals,but could not prevent the colorectal cancer.
