Objective:To study the influences of patients′ online medical service from willingness to behavior based on Anderson′s health service utilization model, and to provide reference for improving the utilization rate of internet medical services.Methods:A total of 66 270 patient data were selected from a self built internet medical platform of a tertiary hospital in Zhejiang province in 2021. Indicators such as time of visit, location of visit, doctor′s online activity, doctor′s title, doctor′s age, doctor′s gender, and disease type were subjected to chi-square test and logistic regression analysis to clarify the impact of different indicators on online medical treatment from willingness to behavior.Results:Of the 66 270 people having a willingness to seek online medical treatment, 39 996 people, accounting for 60.35%, achieved online diagnosis and treatment. Online medical services could break through the constraints of time and space and to promote the patient′s seeking medical treatment online from willingness to behavior in a limited way; Doctor′s title had a non-linear effect on patients′ online medical treatment from willingness to behavior; Doctor′s online activeness significantly promoted online medical treatment from willingness to behavior; Female doctors and middle-aged and young doctors promoted online medical treatment from willingness to behavior; Different types of diseases affected online medical treatment in different ways.Conclusions:Among the factors that affect the patient′s transformation from online medical willingness to behavior, the patient′s enabling resources have a facilitative effect, and need factors have a direct impact.

Objective To investigate the effect of three-dimensional gelatin-chondroitin sulfatehyaluronic acid (Gel-C6S-HA) composite scaffold seeded with genetically modified hair follicle stem cells (HFSCs) on tissue engineering skin angiogenesis.Methods Three-dimensional scaffolds composed of Gel-C6S-HA were fabricated by freeze-lyophilizing.VEGF165 modified HFSCs were seeded on those scaffolds and cellular morphology and adhesion were observed using scanning electron microscope.Eighteen rats were subjected to the full-thickness skin defects with dimensions of 1.2 cm × 1.2 cm on the bilateral sides of the back and covered with VEGF165 transduced HFSCs/Gel-C6S-HA scaffold (Group A),empty-vector transduced HFSCs/Gel-C6S-HA scaffold (Group B),Gel-C6S-HA scaffold (Group C),and vaseline gauze (Group D) respectively according to the random number table.At days 7,14,and 21 after surgery,wound healing was observed,HE staining and immunohistochemistry of CD31 and alpha smooth muscle actin (α-SMA) were performed,and microvessel density (MVD) was used to measure new blood vessel growth.Results Electron microscopy exhibited three-dimensional spongy structure of the scaffold with round or polygon apertures connecting mutually and the scaffold pore size of (133.2 ± 43.4) μm.Cells seeded on the scaffolds spread thoroughly out and anchored firmly after being cultured for 7 days.There were no obvious inflammation reactions on the wounds for all groups at day 7 after operation.Wound healing and scaffold degradation were faster in Group A than in other groups at days 14 and 21 after operation.Histological and immunological detections showed microvasculariztion of the scaffold in Groups A and B with fluffy three-dimensional structure and evenly distributed cells,but scaffolds remained sharp at the edge and there were small cells aggregating at subcutaneous tissue junction area in Group C.At 14 and 21 days after operation,new blood vessels were large and rich in Group A; scaffolds in Groups A and group B were filled with cells,partial of which gathered in the epidermal layer and the scaffold materials were assimilated differentially,whereas a few subcutaneous tissue cells migrated to scaffolds in Group C.MVD was significantly higher in Group A than in Groups B and C at each time point (P ＜ 0.05).Conclusion VEGF165 modified HFSCs compounded with Gel-C6S-HA composite scaffold can facilitate the growth of blood vessels and promote the angiogenesis in wound healing and hence is a promising skin substitute in clinical applications.
