Objective:To understand the satisfaction evaluation of contracted residents with " Internet plus" family doctor services and to explore its influencing factors.Methods:From November to December 2021, a stratified random sampling method was used to select 360 contracted residents who had utilized " Internet plus" family doctor services from community health service centers or township health clinics in various counties, cities, or districts of a city in Shandong Province for on-site questionnaire surveys. The purpose was to understand their awareness and satisfaction with the " Internet plus" family doctor services. At the same time, key informant interviews were conducted with contracted residents according to the principle of intensity sampling and information saturation, to collect their opinions and suggestions on the implementation process and model construction of " Internet plus" family doctor services. Descriptive analysis was performed on the data, and a binary logistic regression model was used to analyze the factors affecting the satisfaction of contracted residents with " Internet plus" family doctor services.Results:352 valid questionnaires were obtained. Among the respondents, 108 (30.6%) were very familiar or relatively familiar with the " Internet plus" family doctor service policy, and 251 (71.3%) expressed a high level of satisfaction with the overall " Internet plus" family doctor service. Gender, monthly income status, frequency of participation in health education activities, and satisfaction with the doctor′s daily service attitude, medical technical level, medical service charge level, and the level of communication between the service team and family members were factors affecting the satisfaction of contracted residents with " Internet plus" family doctor services ( P<0.05). Interview results showed that 38 people (95.0%) believed that there were issues with the current implementation of " Internet plus" family doctor services in China, such as the lack of an effective policy support environment, the need to improve the publicity and mobilization effects of contracting institutions, poor service cognition levels among the population, concerns about service quality, misunderstandings about internet-related concepts, network " panic" caused by electronic fraud phenomena, and cultural level differences among the elderly that limited the use of services. Conclusions:The overall satisfaction of contracted residents with the " Internet plus" family doctor services was relatively good. Various factors affected the satisfaction evaluation of contracted residents. It is important to focus on the differences in service psychological perception among contracted residents with different demographic characteristics, strengthen the construction of service teams and service platforms, and improve the public′s cognition and participation in " Internet plus" family doctor services to promote the continuous development of " Internet plus" family doctor services.

Objective To explore the value of multi-sequence MRI radiomics for predicting clinical stage of cervical squamous cell carcinoma(CSCC).Methods Totally 190 patients with single CSCC confirmed by pathology were retrospectively collected.Among them,67 cases with International Federation of Gynecology and Obstetrics(FIGO)stage ⅠB—ⅡA were classified into early stage group,while 123 cases with FIGO ⅡB—ⅢC were enrolled in middle-late stage group.The patients were divided into training set(n=114,including 40 cases in early stage subgroup and 74 cases in middle-late stage subgroup)and test set(n=76,including 27 cases in early stage subgroup and 49 cases in middle-late stage subgroup)at the ratio of 6∶4.Single factor and logistic analyses were used to screen clinical relevant factors,and a clinical model was constructed.The best radiomics features of lesions were extracted and selected based on pre-treatment pelvic MR T2WI,diffusion-weighted imaging(DWI),dynamic contrast enhancement(DCE)-T1WI and all the three,respectively,and the radiomics models were constructed,including T2WI,DWI,DCE-TWI and combined sequences models,then a clinical-radiomics model was established based on clinical model and combined sequences model.The predictive efficacy of each model was evaluated by receiver operating characteristic curves,and the area under the curves(AUC)were calculated.The integrated discrimination improvement(IDI)index was also calculated to compare the diagnostic efficacy of each model in training set,and decision curve analysis(DCA)was used to evaluate their clinical value.Results Squamous cell carcinoma associated antigen in middle-late stage subgroup was higher than that in early stage subgroup in both training and test sets(both P＜0.05),which was used to establish the clinical model.The AUC of clinical,T2WI,DWI,DCE-TWI,combined sequences and clinical-radiomics models for predicting clinical stage of CSCC was 0.66,0.71,0.78,0.81,0.88 and 0.89 in training set,respectively,which was 0.62,0.64,0.72,0.73,0.77 and 0.76 in test set,respectively.In training set,the predictive efficacy of clinical-radiomics model was higher than that of combined sequences model(IDI=0.19,P＜0.05),both higher than that of the rest models(IDI=0.19-0.47,all P＜0.05).When the thresholds were 0.02-1.00 and 0.05-1.00,combined sequences and clinical-radiomics models had higher clinical net benefits in training set.Conclusion Multi-sequence MRI radiomics could effectively predict clinical stage of CSCC,and combining clinical data could improve its diagnostic efficacy.

Cow 's milk protein allergy（CMPA）is a complex immune reaction mediated by immunoglobulin E（IgE），non-IgE or a mixture of the two.Neonate，as a special group，whose nutrition comes from breast milk and/or formula milk，are prone to CMPA.Studies have shown that genetic factors，environmental factors，immune factors，intestinal mucosal barrier，intrauterine sensitization，diet factors，delivery mode，gestational age may have a certain relationship with the occurrence of neonatal CMPA.This article will make a review on the pathogenic factors of neonatal CMPA from the above aspects，so as to provide clinical basis for its early identification and intervention.

Circular RNA (circRNA) is involved in tumor progression. CircPVT1 is an oncogene that is abnormally expressed and correlated with a variety of tumors. It can regulate tumors' malignant behavior and affect the survival and prognosis of patients. This article reviews research on the regulatory roles of circPVT1 in tumors to provide references for accurate treatment.

OBJECTIVE: To investigate the changes in gray matter volume in depressive-like mice and explore the possible mechanism. METHODS: Twenty-four 6-week-old C57 mice were randomized equally into control group and model group, and the mice in the model group were subjected to chronic unpredictable mild stimulation (CUMS) for 35 days. Magnetic resonance imaging was performed to examine structural changes of the grey matter volume in depressive-like mice. The expression of brain-derived neurotrophic factor (BDNF) in the grey matter of the mice was detected using Western blotting and immunofluorescence staining. RESULTS: Compared with the control mice, the mice with CUMS showed significantly decreased central walking distance in the open field test (P < 0.05) and increased immobile time in forced swimming test (P < 0.05). Magnetic resonance imaging showed that the volume of the frontal cortex was significantly decreased in CUMS mice (P < 0.001, when the mass level was greater than or equal to 10 756, the FDRc was corrected with P=0.05). Western blotting showed that the expression of mature BDNF in the frontal cortex was significantly decreased in CUMS mice (P < 0.05), and its expression began to decrease after the exposure to CUMS as shown by immunofluorescence staining. The volume of different clusters obtained by voxel-based morphometry (VBM) analysis was correlated with the expression level of mature BDNF detected by Western blotting (P < 0.05). CONCLUSION The decrease of frontal cortex volume after CUMS is related with the reduction of mature BDNF expression in the frontal cortex.

Endothelial dysfunction was closely related with AS , NO bioavailability ( production and utilization of endothelial NO ) was decreased by oxidative stress , lipid infiltration , inflammatory factor expression , vascular tone alteration and so on , which play an important role in endothelial dysfunction .Enhanced arginine , activityand asym-metric dimethylarginine together with increased hyperhomocysteinemia all promote AS by intervening NO bioavail -ability.Diabetes mellitus, obesity, chronic kidney disease , smoking and so on also involved in AS via influencing NO bioavailability and NO level .
