China’s existing laws and regulations in telemedicine fall behind practice.As a result, telemedicine is confronted with such vague constraints as permission,legal relations and legal liability, validity of electronic medical records,telemedicine equipment standards,patients’right to know and their right to privacy,as well as disputes settlement.On such basis,the authors propose to improve the laws and regulations in this regard as soon as possible.

The paper introduces the mutual relationship among the innovation of four dimensions including new medical service concept,new patient interface,new service transmission system and new technology of telemedicine based on the illustration of four-dimensional model of service innovation to the telemedicine service,and makes an analysis by taking the telemedicine service innovation of remote medical center in Henan Province as an example,thus providing reference for the innovative development of telemedicine service.

Objective:To analyze the usage intention and key issues of medical staff to use telemedicine, for improving telemedicine service system in China.Methods:From October to November 2019, medical workers of both the inviting party and invited party who experienced telemedicine in seven provinces of Fujian, Hainan, Henan, Hunan, Guizhou, Sichuan and Qinghai were selected for an online questionnaire survey. Areas covered included their usage intention, satisfaction and cognitive appraisal of telemedicine. Descriptive statistical analysis and non-parametric test were used to discuss the intention of further use, satisfaction and challenges of medical workers in various provinces and regions.Results:1 084 valid questionnaires were recovered. The data found the overall satisfaction was 98.62%, and the proportion of their intention of further use was 98.25%, and those from the eastern and western provinces presented higher intention of usage. The top challenges as reflected by these medical workers were named as follows: timeliness of consultation progress and information feedback; long latency time; low Internet speed, poor and interrupted Internet signal; inadequate system equipments and inconvenient operation; difficulties in remote physical checkup and overall understanding of patient conditions; as well as substandard, incomplete and poor medical records.Conclusions:These medical workers are satisfied with the telemedicine services and willing to continue to use telemedicine.For those existing problems, it is suggested to strengthen the infrastructure and optimize the process of telemedicine services, so as to encourage them in greater use of telemedicine.

Objective:To analyze the actual and expected incentives and key issues of telemedicine providers in China and to provide important references for optimizing telemedicine incentive policies.Methods:The sample data came from a questionnaire survey of 1 084 providers in 7 provinces of Fujian, Hainan, Henan, Hunan, Guizhou, Sichuan and Qinghai in October and November 2019 and a semi-structured interview data at 6 hospitals in Henan province in January 2020. Descriptive analysis was used to sort such data into text data for classified summation.Results:The greatest gaps were found between actual incentives and expected ones in expense subsidies, title promotion and excellence awards, with such gaps as high as 18.65, 28.26, 29.28 percentages among providers of junior, deputy senior and senior academic titles respectively. Hospitals fall short in providing adequate incentives for telemedicine providers, not to mention lack of differentiation and diversification in personnel incentives, and poor implementation of incentive policies.Conclusions:It is suggested to strengthen incentive demand analysis, break the homogenization bottleneck of incentive policies, and consolidate internal publicity and implementation of incentive policies.

Telemedicine can optimize deployment of medical resources and minimize diagnosis discrepancies.Formulation of a rational project pricing and scientific compensation policy will be conducive to its future development. The concept of human resource consumption in RBRVS was used as reference to improve the activity-based costing ( ABC ) method. The authors sorted out the resource cost repository, identified the activity system, classified the motivation resources into respective activity cost repositories, and calculated the cost of respective cost object distribution.The cost of three telemedicine service items(remote single discipline consultation, remote image consultation and remote pathology consultation were 119.69, 147.03 and 161.61 yuan respectively) was calculated by the improved ABC.It can better indicate project costs than that calculated by the traditional ABC(137.30, 147.17 and 144.08 yuan), and proves more consistent with the existing prices of other province(134.00, 150.00 and 174.00 yuan).

Objective: The connectivity alterations in the putamen were found in revealing the neural correlates of attention-deficit/hyperactivity disorder (ADHD), but whether the effective connectivity of the putamen is atypical in ADHD remains unclear. Investigating this abnormality contributes to describing the neural circuit of ADHD at the level of macrostructural organization. Methods: Data were acquired from thirty-two boys with ADHD and fifty-two matched typically developing controls (TDC) from Peking University (Peking) dataset deposited at the Neuroimaging Informatics Tools and Resources Clearinghouse (NITRC) platform. We examined the effective connectivity of the putamen using Granger causality analysis (GCA) and then determined whether these connections could differentiate ADHD from TDC. Results: Compared with TDC, the ADHD group showed decreased effective connectivity from the left ventral rostral putamen (VRP) to left calcarine (CAL), right medial part of the superior frontal gyrus, left orbital part of superior frontal gyrus and left middle occipital gyrus (MOG). Increased effective connectivity from the left inferior occipital gyrus and right lingual gyrus to left VRP was also found in ADHD. The result of the classification accuracy showed that 72.3% of participants were correctly classified using support vector machine. Moreover, GCA values from the left VRP to left CAL and left MOG were significantly correlated with hyper/impulsive scores of patients with ADHD. Conclusion The findings may help extend our understanding of the ADHD-related neural loops.

Objective: To understand effects of timing and duration of separation experiences from parents on emotion regulation of left-behind preschoolers,and to provide the reference for phychological instruction and intervention among the special groups of children. Methods: Children’s emotion regulation strategy and the relevant information among 1 373 left-behind preschool children from Funan county in Fuyang.Qianshan county in Anqing,Changfeng county and Fexi county inFeixi were investigated. Results: Children with left-behind experiences younger than 18 months old tend to use less cognitive restructuring (P=0.03) and alternative action strategies (P=0.00) than non-left behind children. Children separated from father less than 47 months (median) and 36 months (median) from mother tend to use less cognitive restructuring (P=0.00) and alternative action strategies (P=0.00) than non-left behind children. Conclusion Separation experiences from parents younger than 18 months old exert severe damage on children’s emotional regulation. With the duration of separation increases, children show resilience of emotion regulation, which might be a protective factor for negative emotion due to parent-child separation.

OBJECTIVETo summarize the application of protective terminal ileostomy in laparoscopic total mesorectal excision for rectal cancer patients, and explore the risk factors associated with postoperative complications and timing of stoma closure.

METHODSClinical data of 77 patients with middle or low rectal cancer undergoing laparoscopic total mesorectal excision (TME) with preventive terminal ileostomy in our department from January 2007 to December 2013 were retrospectively analyzed. Independent risk factors associated to postoperative complications of terminal ileostomy were examined by logistic regression and timing of stoma closure was investigated.

RESULTThe total postoperative complication morbidity was 57.1% (44/77). Electrolyte disturbance was found in 39 cases (50.6%, 39/77), including 1 case of hypovolemic syncope. Parastomal hernia occurred in 9 cases (11.7%, 9/77). Peristomal dermatitis and subcutaneous abscess was observed in 1 case (1.3%, 1/77). The result of the single factor analysis of the water electrolyte disturbance after operation, the risk factors of P<0.2 were new adjuvant chemotherapy (P=0.094), tumor antigen (P=0.086) and TNM staging (P=0.026); Postoperative parastomal hernia of the single factor analysis results, the risk factors of P<0.2 included uses of antidiabetic drugs (P=0.172), ASA anesthesia (P=0.168) grading and TNM stage(P=0.161); But multivariate analysis revealed no risk factors associated with the above complications (all P>0.05). Sixty-five patients underwent stoma closure during follow-up, including 2 cases (3.1%) within 90 days, 20 cases (30.8%) from 90 to 180 days, and 43 cases (66.2%) more than 180 days.

CONCLUSIONSNo risk factors were found to be associated with main postoperative complications of protective terminal ileostomy after laparoscopic TME for rectal cancer patients, such as electrolytes imbalance and parastomal hernia. The timing of stoma closure should be longer than 180 days.

Objective To know the anxiety status of preschool children in rural areas and to explore its influential factors. Methods Subjects of 1363 rural preschool children aged 3-6 years were selected from Anhui Province( Changfeng and Feixi county of Hefei city; Qianshan county of Anqing city; Funan county of Fuyang city) . The primary caregivers of preschool children were investigated by Chinese version of Spence Preschool Anxiety Scale (SPAS),Devereux Early Childhood Assessment for Preschoolers (DECA-P2) ,Neglect Norms for Children Aged 3 to 6 Years in Rural Areas of China,Adaptation Partnership Growth Affection Resolve (APGAR),Self-rating anxiety scale (SAS) and Self-rating depression (SDS). Result-s Among the 1363 preschool children,the positive rate of anxiety was 14. 7％. Physical injury fears score was highest (1. 24±0. 84),followed by social phobia anxiety (0. 86±0. 75) and separation anxiety (0. 85± 0. 74) . Except for obsessive compulsive disorder,the other four types of anxiety and total anxiety scores were negatively correlated with the total protective factors of mental resilience (r=-0. 054- -0. 070,P<0. 05). Besides,all anxiety scores were positively correlated with behavioral problems(r=0. 121-0. 237,P<0. 05)and neglect degree (r=0. 157-0. 269,P<0. 05). The results of multiple linear regression analysis of different anxiety types showed that gender,family type,family income status,parental rearing pattern was consistent or inconsistent,children' s neglect degree,behavior problem and anxiety/depression status of primary caregivers were the main factors affecting the anxiety level of preschool children in rural areas. Conclusions In order to reduce or avoid anxiety of preschool children,it is necessary to establish a good family environment,im-prove parents' upbringing level,and take effective education intervention.
