Expert Concensus on Triune Personalized Treatment of Pelvic Tumor Based on Three-Dimensional Printing / 医用生物力学

The adjacent anatomy of the pelvis is complicated, with digestive, urinary, reproductive and other organs as well as important blood vessels and nerves. Therefore, accurate resection of pelvic tumors and precise reconstruction of defects after resection are extremely difficult. The development of medical 3D printing technology provides new ideas for precise resection and personalized reconstruction of pelvic tumors. The “triune” application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis in pelvic tumor limb salvage reconstruction treatment has achieved good clinical results. However, the current lack of normative guidance standards such as preparation and application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis restricts its promotion and application. The formulation of this consensus provides normative guidance for 3D printing personalized pelvic tumor limb salvage reconstruction treatment.

How Competitive Orientation Influences Unethical Decision-making in Clinical Practices?

PURPOSE: This study aims to investigate how competitive orientation influences unethical decision-making (UDM) through relationship conflict and the moderating effect of hostile attribution bias. METHODS: This study was conducted using a self-report questionnaire. Data were collected from 727 employees in Chinese hospitals. For each variable, measures were adopted or adapted from existing literature. Data were analyzed using descriptive statistics, correlation analysis, confirmatory factor analysis, and hierarchical regression analysis. Common method variance was established using Harman's single-factor test. RESULTS: Competitive orientation is significantly and positively associated with relationship conflict (β = .36, p < .001) and UDM (β = .35, p < .001). Relationship conflict is significantly and positively associated with UDM (β = .51, p < .001). Relationship conflict partially mediates the relationship between competitive orientation and UDM. In addition, hostile attribution bias strengthens the positive relationship between competitive orientation and UDM through relationship conflict. CONCLUSION: This study provides some implications for hospital employees to deal with ethical dilemmas in decision-making. Hospital employees including nurses, physicians, and other health-care professionals should raise awareness of competitive orientation and adopt a cooperative approach to human relations. Effective training programs should be utilized to direct all hospital employees to depress hostile attribution bias whenever possible to everything in clinical practice.

3D printing technology applied in orthopaedics / 中华骨科杂志

3D printing is an important technology occurs in 1980s,which has been about more than 30 years since the first 3D printing machine was developed.Currently,it develops rapidly and its application scope has been greatly expanded.Its most prominent features are the "personalized" printing and the diversification of "printing ink".The "personalized" printing can make it possible to tailor the biological materials for each patient,and the diversity of "printing ink" can make the technology meeting different clinical needs.3D printing can be divided into four aspects:l) the collection and formation of inage of printing object;2) the treatment and the transformation of the image information;3) printing based on the data formatted;4) the post-treatment and pedormance evaluating of the printing object.At present,the common methods related to orthopaedics include:1) stereolithography appearance;2) selective laser sintering;3) fused deposition modeling;4) laminated object manufacturing;5) the direct metal melting technology (selective laser melting or electron beam melting);6) the ink jet printing technology.A variety of materials have been used in 3D printers,including the natural medical materials like collagen and chitosan,the synthetic polymers like polylactic acid,polyglycolic acid and peek,the bioactive ceramic materials like hydroxyapatite,the medical metal materials like titanium.The 3D printed material are mainly used in the following seven aspects in orthopaedics:1) the preoperative planning,such as the printing of the lesion and resection model;2) operation navigation make the surgery procedure more accurate;3) making the customized prosthesis and implant;4) implanting the external fixation;5) the development of new surgical instruments meets the special needs of patients;6) making the personalized tissue engineering scaffold used in regenerative medicine;7) the development of drug and its release study.
