The patients are in a relatively disadvantaged position in the relationship between doctors and patients.In order to safeguard an equal and harmonious doctor-patient relationship,society and hospital administrators usually emphasize on doctors' responsibility in constructing the harmonious doctor-patient relationship,which is not a comprehensive consideration.This paper shows that the contradiction between the patients and doctors lies on the differences between them and the both have responsibilities.However,the evaluation from the media is not objective,and the awareness of the role of patients has enhanced,all of which lead to a distrust to the doctors and even a deterioration of their relationship.The author analyzes the reasons above from both theoretical and practical point of view and points out that the patients should bear certain responsibility for the doctor-patient relationship.Furthermore,the author puts forward several countermeasures to construct a harmonious relationship between doctors and patients,such as creating an objective direction of public opinion and social environment,propagandizing the knowledge about medical risk,raising the level of the awareness of moral responsibility.

Objective To establish a method of GC for determination of Waishang Ruyi Ointments.Methods WAX PEG-20M capillary column was used.The column temperature was 140 ℃,the injection port temperature was 230 ℃,the detector temperature was 250 ℃,the flow rate was 1.0 mL/min.Results For Waishang Ruyi Ointments,the linear range was 0.513 8～5.138 mg,and the average recovery rate was 96.2% with RSD=1.0%.Conclusion The method is simple,easy-to-use,and can effectively control the quality of the ointments.

Objective To evaluate the value of contrast-enhanced ultrasonography (CEUS) in quantitative diagnosis of chronic kidney dysfunction(CKD) by comparing it with color Doppler imaging (CDFI). Methods Tirty-three cases (15 males and 18 females) of clinical confirmed CKD (stage Ⅲ～Ⅴ)were included. Forty-five healthy volunteers were performed as control group. CEUS and CDFI were performed on each patient. After intravenous bolus injection of 1ml SonoVue each side,CEUS of renal cortex blood perfusion was collected successively,and a time-intensity curve(TIC) was created with Philips iU22 system's QLAB software. Resistance index(RI) and peak systolic velocity(PSV) of renal partial arteries were also tested. Results Compared with normal kidney,CKD patients had delayed perfusion and decreased intensity. Changes of area under curve(AUC), derived peak intensity(DPI), slope rate of ascending curve(A)and time to peak(TTP) were statistically significant ( P ＜0. 05). Sensitivities of AUC,DPI,A and TTP in diagnosis of CKD (stage Ⅲ～Ⅴ ) were 91.2% ,84. 9% ,90.9% and 85.3%, their specificities were 95.4%,88.9% ,93.3% and 90.9%, their accuracies were 93.6%, 87. 2%, 92.3% and 88. 5%, respectively. The results of CEUS were better than RI in CDFI (sensitivity 70.4%, specificity 37. 8%, accuracy 52.2%).Conclusions CEUS can precisely display the hemodynamic change in CKD ( stage Ⅲ～Ⅴ ), and is more sensitive than CDFI.

Objective: The aim of this review was to identify the possible mechanisms behind cupping therapy by employing an evidence-based approach,and to explore its possible regional and systemic effects in the human body.Methods: We searched six electronic databases and four online trial registries for articles published up to January 1,2020.Clinical studies on the mechanisms of retained cupping,flashing cupping,moving cupping,and vacuum cupping were considered for this review.The methodological qualities of controlled studies were assessed using the National Institute for Clinical Excellence methodology checklist,the Newcastle-Ottawa Scale,and the Cochrane risk of bias tool.Characteristic statistical description and qualitative summary of results were used for data analysis.Results: Thirty-eight studies(37 full texts and one abstract)were included in this study.Due to the clinical heterogeneity among the studies,we could not conduct a meta-analysis.The results showed that the key factors that contribute to the efficacy of cupping therapy are negative pressure and temperature.Cupping therapy mainly causes local and systemic changes in hemodynamics,immune regulation,metabolism,and pain relief.Conclusion: We identified negative pressure as the key element behind cupping therapy.Cupping therapy may cause redistribution of oxygen at the cupping site and in neighboring tissues,thereby inducing a therapeutic effect by increasing regional blood flow.It may also induce metabolic change,immunomodulation,and neuromodulation.However,additional rigorous clinical research needs to be conducted to further clarify the mechanism behind cupping therapy.

Objectives:To investigate the association between social determinants of health(SDOH)and incident stroke and analyze the main risk factors for stroke among resident with different SDOH levels. Methods:From 2012 to 2015,30 036 residents(≥35 years old)from 30 districts in 14 provincial-level administrative divisions in China were enrolled this study based on stratified multi-stage-random-sampling method.The prevalence of cardiovascular diseases and related risk factors were investigated,and stroke events were followed up in 2018 to 2019.Principal component analysis was performed to establish SDOH scores based on 9 indicators related to socioeconomic and healthcare resources,participants were divided into low SDOH group(n=8 343)when it was≥-2.01 to<-1.14,middle SDOH group(n=7 257)when it was≥-1.14 to<0.10,and high SDOH group(n=8 457)when it was≥0.10 to≤5.79.Multivariate Cox regression was applied to estimate the association of SDOH levels with incident stroke.The random survival forest method was used to analyze the major risk factors in different SDOH levels. Results:A total of 24 057 participants were finally included,669(2.8%)participants developed stroke during a mean of(4.7±0.8)years follow-up.The incidence densities of stroke in the low,medium,and high SDOH groups were 468.39,628.85,and 700.39/100 000 person-years,respectively(Pdifference<0.05,Ptrend=0.01).Compared with individuals with low SDOH level group,fully HR for incident stroke among those with medium and high were 1.91(95%CI:1.54-2.36)and 1.59(95%CI:1.30-1.95),respectively(Ptrend<0.001).Advanced age is the primary risk factor for stroke in the population,especially in districts with high SDOH level.In districts with medium SDOH level,diabetes is an important risk factor for stroke.High blood pressure and alcohol consumption are important modifiable risk factors in low SDOH level districts. Conclusions:Present study shows that higher levels of SDOH are associated with increased risk of stroke.The main risk factors for stroke differ among participants with different SDOH level districts.Targeted interventions should be implemented to improve the prevention and treatment of stroke in populations with different levels of SDOH.
