Spillover Effects of Paid Functions on Physicians' Unpaid Knowledge Activities: Quasi-Experimental Approach.

Background: To promote sustained contributions by physicians to online health care communities, these platforms have introduced a content payment model that offers economic incentives for physicians' online knowledge activities. However, the impact of these paid features on unpaid knowledge activities remains unexplored.

Objective: This study investigated how the introduction of economic incentives in online medical communities affects physicians' unpaid knowledge activities in the community.

PET/CT Examination of Teratomas after Stem Cell Transplantation for a Spinal Cord Injury: A Case Report.

Background: In clinical practice, stem cell transplantation has become an effective method for treating spinal cord nerve injury. Up to now, there has been no report on teratoma caused by transplanted stem cell's abnormal differentiation in the clinic, especially in the analysis of imaging manifestations. Therefore, this article aims to analyze the PET/CT imaging manifestations of teratoma caused by stem cell transplantation to improve the imaging diagnosing capability.

How Do Team-Level and Individual-Level Linguistic Styles Affect Patients' Emotional Well-Being-Evidence from Online Doctor Teams.

Background: In the post-epidemic era, online medical care is developing rapidly, and online doctor teams are attracting attention as a high-quality online medical service model that can provide more social support for patients.

Methods: Using online doctor teams on the Haodf.com platform as the research subject, this study investigates the key factors in the process of doctor-patient communication, which affects patients' emotional well-being.

Effect of changes in the menstrual cycle and age on the signal intensity of amide proton transfer imaging in the normal uterus: a preliminary study.

Purpose: To analyze the effect of changes in the menstrual cycle and age on the signal intensity of amide proton transfer (APT) imaging in normal uterine structures.

Methods: Thirty-one healthy females (age: 21-50 years old) underwent regular pelvic MRI and APT sequences during their menstrual cycle. The APT values of the endometrium, myometrium, and junctional zone were measured.

Examining Patterns of Information Exchange and Social Support in a Web-Based Health Community: Exponential Random Graph Models.

Background: Although an increasing number of studies have attempted to understand how people interact with others in web-based health communities, studies focusing on understanding individuals' patterns of information exchange and social support in web-based health communities are still limited. In this paper, we discuss how patients' social interactions develop into social networks based on a network exchange framework and empirically validate the framework in web-based health care community contexts.

Objective: This study aims to explore various patterns of information exchange and social support in web-based health care communities and identify factors that affect such patterns.

A variant in KCNQ1 gene predicts metabolic syndrome among northern urban Han Chinese women.

Background: Previous studies have reported that the potassium voltage-gated channel subfamily Q member 1 (KCNQ1) gene is associated with diabetes in both European and Asian population. This study aims to find a predictable single nucleotide polymorphism (SNP) to predict the risk of metabolic syndrome (MetS) through investigating the association of SNP in KCNQ1 gene with MetS in Han Chinese women of northern urban area.

Methods: Six SNPs were selected and genotyped in 1381 unrelated women aged 21 and above, who have had physical check-up in Shandong Provincial Qianfoshan Hospital.
