Doctor-patient relationship has attracted increasing attention.In the light of modern model to study the related theory,a preliminary study of the ancient Chinese doctor-patient relationship model has been done.The doctor-patient relationship in ancient society is the same complex and multi-level.Therefore,doctor-patient model could not be lumped together.According to the social status of patients and the extent of their demand for medical services,and the social status of doctors and their medical technique,the doctor-patient relationship could be divided into three typies-equality type,authority type,and principal and subordinate type.With a view of doctor-patient relationship of traditional Chinese medicine,there draws an acquisition value of the current complex patient relationship.

Objective To explore the association between the polymorphism rs671 site of the acetaldehyde dehydrogenase 2 (ALDH2) gene and H-type hypertension in the elderly in Han nationality in Qingdao.Methods Totally 406 patients aged 60-90 years with primary hypertension were randomly selected in the study.Serum levels of homocysteine(Hcy),folate and vitamin B12 were determined and all patients were divided into H-type hypertension group and non H-type hypertension group.Gene chip technology was used to analyze the ALDH2 (rs671) polymorphism,and the association between ALDH2 gene and H type hypertension was evaluated.Results Of all hypertensive participants,82.0％ (333/406) were in H-type hypertension,87.4％ (221/253) in male and 73.2％ (112/153) in female.The GA/AA genotype and A allele frequency were higher in H-type hypertension group than in non H-type hypertension group [37.2 ％ (124/333) vs.16.4 ％ (12/73) and 21.3％(71/333) vs.9.6％(7/73),P=0.001and 0.021].Serum Hcyleveland the prevalence of H type hypertension were higher in GA/AA genotype group than in GG genotype group(both P＜ 0.05).Logistic regression analysis showed that GA/AA genotype,gender (male),drinking,folate deficiency and increased systolic pressure were the risk factors for H-type hypertension (OR=3.17,2.14,2.37,0.75,1.03,respectively,all P＜ 0.05).Conclusions The genetic variation of ALDH2(rs671) may increase Hcy level by decreasing the levels of folate and vitamin B12.GA/AA genotype is a risk factor for H-type hypertension,and it contributes to H-type hypertension together with gender,drinking history,folate levels and systolic pressure.

Objective To analyze the impact of medical insurance reimbursement mechanism on the income of urban community health centers run by various entities. Methods The data of the baseline survey of community health centers in 28 cities made in 2007 were called into play. These data were used to compare the percentage of the annual medical insurance income from outpatient clinics of three types of community health centers in their gross annual income and their annual outpatient clinic income. Results For 929 community health centers with income from medical insurance reimbursement, the average percentage of their annual income from outpatient clinic accounts for 24% of their gross annual income and 26. 09% of their annual outpatient income;In respect of the reimbursement rates of medical insurance at outpatient clinics, the highest come from those run by enterprises, secondly those by the government,and the least those run by social organizations or individuals. Conclusion The mechanism of medical insurance reimbursement has already affected the income of the third type of community health centers. It is recommended to raise the coverage rate of medical insurance of such type of centers and their reimbursement rates of medical insurance. This may further consolidate the policies of medical insurance reimbursement.

Objective To investigate the influence of Ulinastatin (UTI) on the hyper-permeability of vascular endothelial cells induced by tumor necrosis factor alpha (TNF-α).Methods Inflammation model was induced by TNF-α in human umbilical vein endothelial cell line (EA.hy926).The experiment was designed into 4 groups:normal group,TNF-α group,UTI group and TNF-α with UTI (U + T) group.Methyl thiazolyl tetrazolium (MTT) method and epithelial voltameter (EVOM) method were used to measure cell viability [absorbance (A) value] and transepithelial electrical resistance (TER) of EA.hy926 cells respectively.The expression of VE-cadherin was measured by reverse transcription polymerase chain reaction (RT-PCR) and immunocytochemistry.Results Compared with normal group,the TER of EA.hy926 cells induced by TNF-α was significantly decreased (67.200 ± 8.937 vs.33.600 ± 8.771,P =0.010).The permeability in EA.hy926 cells increased obviously.The hyper-permeability of EA.hy926 cells induced by TNF-α could be alleviated by UTI at the concentrations of 1-100 U/mL in a dose-dependent manner (40.133 ±7.484 vs.33.600 ±8.771,P=0.382;49.232 ± 3.162 vs.33.600 ± 8.771,P =0.044;63.700 ± 8.515 vs.33.600 ± 8.771,P =0.013).The expression of VE-cadherin mRNA reduced significantly in the TNF-α group (1.089 ±0.018 vs.0.835±0.021,P =0.000) compared with normal group.This effect of TNF-α could be attenuated by UTI.When EA.hy926 cells exposed to UTI at 10 U/mL and 100 U/mL,a significant increase of the expression of VE-cadherin mRNA was observed (0.976 ±0.014 vs.0.835 ±0.021,P =0.001;1.115 ±0.015 vs.0.835 ± 0.021,P =0.000).And the inhibition of UTI manifested a dose-dependent manner (1-100 U/mL).The results of the immunocytochemistry showed that the expression of VE-cadherin in TNF-o group was decreased significantly (0.061 ± 0.013 vs.0.093 ± 0.014,P =0.049) compared with normal group.And the low-expression of VE-cadherin could be alleviated by UTI (0.032 ± 0.004 vs.0.061 ± 0.013,P =0.016).Conclusion The high permeability of EA.hy926 cells induced by TNF-α could be inhibited by UTI at the concentrations of 1-100 U/mL in a dose-dependent manner.

Objective:To prepare the egg yolk immunoglobulin Y ( IgY) against human Sucrase and study its stability,in vitro activity. Methods:Hy-line laying hens were immunized with human Sucrase protein,IgY was isolated and purified from egg yolks of im-munized hens using water dilution and salting out method. Indirect ELISA was used to evaluate the titer and stability of IgY. The purity and specificity of IgY were analysed by SDS-PAGE and Western blot respectively. The inhibitory effects of IgY on α-glucosidase was studied by PNPG method. Results:Indirect ELISA results showed IgY could be detected on the tenth day after the first immunization, and the peak titer of IgY was 1:12 800 after the 40th day of immunization. SDS-PAGE showed that the heavy chain and light chain of IgY were 65 kD and 25 kD respectively, and the IgY against human Sucrase could specifically recognize the protein of human Sucrase. The IgY maintained primary titer when it was kept between 29-69℃ for 15 min,and pH 4-7,37℃,4 h. The titer of IgY was maintained 50% after digestion by pepsin and trypsin respectively for 2 hours. IgY had a higher resistence to pepsin than trypsin after longer digestion time. IgY showed an inhibitory effect on α-glucosidase in concentration dependent manner. The half inhibitory concentration (IC50) was 0. 540 mg/ml. Conclusion:The IgY against human Sucrase has been successfully obtained,which established foundations for its study of Type 2 diabetes mellitus rat models in vivo.

Objective To elucidate the roles of TANK-binding kinase-1(TBKl)in hepatitis B virus (HBV)infection induced interferon antiviral immunity.Methods Peripheral blood monocytes were separated by CD14 magnetic microbeads from healthy volunteers(HV)and chronic hepatitis B(CHB)patients.Purified mDCs were induced and proliferated in the culture medium with human granulocyte-macrophage concentration of 25 mg/L were stimulated.The mRNA expressions of TBK1,interferon regulatory factor (IRF)3 and interferon(IFN)-βwere quantified by real time polymerase chain reaction(PCR).The levels of IFN-β in supernatants were determined by enzyme-linked immunosorbent assay(ELISA).Reslllts The mRNA levels of TBK1,IRF3 and IFN-β did not change significantly at 0,12,24 and 48 h after the significantly at 0, 12, 24 and 48 h in CHB group, whereas, it was significantly up-regulated at 12 h in HV group. Conclusions Our results suggest that there may be some disorders in host antiviral signal transduction pathways downstream the binding between ligands and receptors on mDC surface. The insufficient IFN-β expression after HBV infection may result in persistent chronic infection.

Objective: To explore the relationship between abuse experience with suicidal ideation and suicide attempts of junior middle school students, and to provide a reference for suicide prevention of junior middle school students. Methods: Cluster sampling method were used to selct 10 289 junior middle school students from 25 districts and counties of Chongqing were included in the analysis of this study from July to September in 2020. And Questionnaire on Abuse in Childhood and Mental Health Scale for Middle School Students were applied to collect the data about demographic information, suicide ideation and behavior. Results: The prevalence of suicidal ideation and suicide attempts among junior middle school students were 20.93% and 10.83%, respectively. Multivariate Logistic regression model found that after controlling for demographic variables and mental health, emotional abuse ( OR =2.07) and emotional neglect ( OR =2.03) showed higher correlations with suicidal ideation than the other three types of childhood abuse( OR physical neglect =1.19, OR physical abuse =1.60, OR sexual abuse =1.37, P <0.05); and sexual abuse ( OR =2.29) and physical neglect ( OR =1.87) showed higher associations with suicide attempt than the other three types of abuse( OR emotional abuse =1.63, OR emotional neglect =1.59, OR physical abuse =1.50, P <0.01). Conclusion All five types of child abuse were independent risk factors for suicidal ideation and suicide attempts, and emotional neglect and emotional abuse had a greater effect on suicidal ideation, sexual abuse and physical neglect had a greater effect on suicide attempts.

Objective:To evaluate the effectiveness of mentorship-Leichester assessment package (LAP) model in general practice teaching.Methods:Sixty five-year Traditional Chinese Medicine (TCM) students undergoing general medicine internship from July 2020 to December 2020 were divided into study group and control group with 30 students in each group. Students in study group undertook general practice internship in Fangzhuang Community Health Service Center with the mentorship-LAP model, including group-based teaching, weekly LAP case discussion and mentor-intern individualized LAP clinical practice teaching; students in control group undertook general practice internship in other community teaching bases with the traditional clinical practice training methods. After one month, students were evaluated with LAP score sheet and the evaluation results were compared between two groups.Results:After one month of training, the scores of medical history collection, physical examination, problem solving, patient management, doctor-patient relationship, expected care and medical records in both groups increased compared with pre-training (the control group: t=4.23, 5.06, 8.94, 4.85, 3.99, 1.04, 5.13, study group: t=1.86, 2.85, 12.42, 13.61, 6.29, 4.83, 5.63, all P<0.05). The scores of medical history collection, physical examination, problem solving, patient management, doctor-patient relationship, and expected care after training in the study group were higher than those in the control group ( t=5.66, 2.83, 5.67, 8.13, 2.76, 2.52, all P<0.05). After the training, in the medical history collection items, the scores of patient-centered communication, RICE recognition, and physical-psychological-social factors in study group were higher than those in the control group ( t=5.66, 7.35 and 2.66, all P<0.05); in the problem-solving items, the scores of clinical data application, comprehensive analysis ability and personal ability limitation in study group were higher than those in the control group ( t=4.32, 3.38 and 2.26, all P<0.05); in the patient management items, the scores of overall management plans, doctor-patient collaboration, dispelling doubts, subsequent visits/follow-up, and the degree of patient understanding the management plan in the study group were higher than those in the control group ( t=3.03, 2.07, 2.43, 3.15 and 2.17, all P<0.05). Conclusion:The mentorship-LAP teaching model is helpful to improve the effectiveness of general practice internship for medicine students.

Objective:To investigate the correlation between social and linguistic parenting behaviors and developing capability of children with autism.Methods:From August 2020 to December 2020, the social and linguistic parenting behaviors of 302 parents of children diagnosed with autism were investigated in the outpatient department of the hospital.Meanwhile, the data of Gesell scale for children, the social life competence scale for infant and junior middle school students, the autism behavior checklist and the Cancy autism behavior scale were collected.SPSS 20.0 software was used for statistical analysis.Independent sample t test and analysis of variance were used to compare the social and linguistic parenting behaviors of different parents.Pearson correlation analysis was used to analyze the correlation between the social and linguistic parenting behaviors of parents and children's developmental ability and symptom severity. Results:There were no statistically significant differences in children's social and language development parenting behavior between father and mother ( t=1.033, P=0.303; t=-0.312, P=0.756). There were no statistically significant differences in children's social and linguistic parenting behaviors between fathers of different age groups ( F=1.425, P=0.244; F=1.127, P=0.345). Among mothers of different age groups, the social parenting behaviors of <30 years old and 30-34 years old groups were significantly better than those of 35-39 years old group ( F=3.374, P=0.019; LSD: P=0.010, P=0.006). Among fathers, the social parenting behavior( F=4.346, P=0.008; LSD: P=0.020, P=0.001) and social + linguistic parenting behavior in the graduate group and college group were significantly better than those in the high school/vocational group( F=3.965, P=0.012; LSD: P=0.020, P=0.002). Among mothers, the social parenting behavior ( F=2.812, P=0.040; LSD: P=0.008, P=0.023, P=0.009), linguistic parenting behavior ( F=3.769, P=0.011; LSD: P=0.010, P=0.025, P=0.001), social + linguistic parenting behavior ( F=3.654, P=0.013; LSD: P=0.005, P=0.015, P=0.002) in graduate and above groups were significantly better than those in college group, high school/vocational group, junior high school and below groups.The scores of social parenting behavior(40.72±6.80), linguistic parenting behavior(27.20±5.22), and social + linguistic parenting behavior(67.92±11.10) were significantly correlated with children’s fine motor(61.75±16.41)( r=0.193, P=0.001; r=0.153, P=0.009; r=0.190, P=0.001), cognition(68.28±16.83)( r=0.231, P=0.000; r=0.186, P=0.001; r=0.229, P=0.000), language(53.01±18.55) ( r=0.262, P=0.000; r=0.305, P=0.000; r=0.304, P=0.000) and social self-care(61.44±17.85) ( r=0.264, P=0.000; r=0.238, P=0.000; r=0.274, P=0.000). The scores of linguistic parenting behavior and social + linguistic parenting behavior were correlated with children's social life ability (8.65±0.89) ( r=0.142, P=0.046; r=0.140, P=0.049). There was no significant correlation between social parenting behavior, linguistic parenting behavior, social + linguistic parenting behavior and the scores of ABC scale (50.53±21.39) ( r=-0.089, P=0.336; r=-0.115, P=0.215; r=-0.107, P=0.250) and CABS scale (13.96±4.54) ( r=-0.050, P=0.490; r=-0.059, P=0.411; r=-0.058, P=0.421). Conclusions:The social and linguistic parenting behaviors are related to their age and educational level, and are significantly correlated to developing capability of children with autism, but have nothing to do with the severity of children's symptoms.
