Relationship of common dyadic coping to marital satisfaction and quality of life for patients with brain injury and their spouses in a rehabilitation facility: using common fate model / 中国康复理论与实践

ObjectiveTo investigate common dyadic coping (CDC) in linking with marital satisfaction and quality of life (QOL) in patients with brain injury and their spouses in a rehabilitation facility by using common fate model (CFM). MethodsFrom October, 2022 to June, 2023, 101 brain injury inpatients and their spouses in Beijing Bo'ai Hospital completed the questionnaire of Dyadic Coping Inventory, Kansas Marital Satisfaction Scale and World Health Organization Quality of Life. ResultsThe level of CDC between patients and their spouses significantly positively correlated with their marital satisfaction for both partners (β = 0.814, P < 0.001), as well as correlated with their quality of life (β = 0.271, P = 0.038; β = 0.481, P < 0.001). For the dimensions of QOL, the physical, psychological, social relationship and environmental dimensions significantly positive correlated with the CDC for the spouses, and only psychological and social relationship dimensions for the patients. ConclusionFacing the stress of brain injury, the level of CDC within couples can positively predict their marital satisfaction and QOL, and effect seems stronger for the spouses. It is advisable to consider both brain injured patients and their spouses as a whole to promote psychological adaptation and improve rehabilitation outcomes.

Intervention effects of health management program based on WeChat platform for high-risk obese diabetic population / 中华健康管理学杂志

Objective To determine the effects of a health management program based on WeChat platform of overweight and obese diabetic high-risk population and to provide the basis for developing a scientific and effective weight loss program. Methods A total of 123 overweight and obese diabetic cases were identified during health examinations and were randomly divided into intervention(n=62)and control (n=61)groups.In the control group,traditional health lectures once a week for 3 months were conducted.In the intervention group,based on the control group using a micro-classroom setting to give diet and exercise interventions, diabetes information and intervention programs were uploaded to the WeChat learning platform, arranged at a fixed time with the patient online learning exchange, and with complete follow-up services. Low-energy intake therapy was used for diet intervention program, the daily calorie intake decreased by 15% to 40%;aerobic exercise combined with appropriate strength training were used as part of the exercise intervention program.Both groups were followed up for 1 year,measuring the dietary,exercise compliance, body mass index (BMI), body fat, total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and fasting blood glucose (FBG) levels. Blood lipids, blood glucose, and weight loss were analyzed using an independent sample t-test and χ2test. Results The difference in the educational participation rate between the intervention (81.0%, 583/720) and control (72.9%, (516/708) groups was statistically significant(χ2=13.18,P<0.05).The reasonable proportions of carbohydrate,protein, fat, and salt were 85.0%, 70.0%, 73.0%, and 75.0%, respectively, in the intervention group, which were significantly higher than those in the control group(66.0%,47.6%,49.2%,and 52.5 %,respectively),The difference was statistically significant(χ2=5.76,6.24,7.34,6.50,all P<0.05).To compare the daily effective exercise time,the intervention group(22.8±2.1)min was significantly longer than the control group(16.2± 1.8)min,with a statistically significant difference(t=18.33,P<0.01).The TC,TG,LDL-C,and FBG levels in the intervention group [(4.9 ± 0.4) mmol/L, (1.5 ± 0.2) mmol/L, (2.7 ± 0.3) mmol/L, and (4.9 ± 0.6) mmol/L, respectively]were significantly lower than those in the control group[(5.6±0.4)mmol/L,(2.1±0.2)mmol/L, (3.9±0.3)mmol/L,and(5.8±0.6)mmol/L,respectively].The BMI in the intervention group(24.3±2.8)kg/m2 was significantly lower than that in the control group(27.8±2.9)kg/m2.Moreover,the mean level of body fat in the intervention group (19.6 ± 1.9) kg was lower than that in the control group (22.6 ± 2.1) kg, with a statistically significant difference (t=9.54, 15.93, 22.56, 8.54, 6.72, 8.22, all P<0.01). The effective rate of weight loss and fat loss was 65.0% and 60.0% in the intervention group,which were significantly higher than those in the control group (35.6% and 32.2%, respectively), with a statistically significant difference (χ2=10.29, 9.25, all P<0.05). Conclusion The health management program based on a micro-letter platform can improve the participation in the intervention and reasonable diet and exercise compliance and effectively reduce the weight and blood lipid and glucose levels of overweight and obese diabetic patients.

Compressive force regulates ephrinB2 and EphB4 in osteoblasts and osteoclasts contributing to alveolar bone resorption during experimental tooth movement / 대한치과교정학회지

OBJECTIVE: To investigate the involvement of ephrinB2 in periodontal tissue remodeling in compression areas during orthodontic tooth movement and the effects of compressive force on EphB4 and ephrinB2 expression in osteoblasts and osteoclasts. METHODS: A rat model of experimental tooth movement was established to examine the histological changes and the localization of ephrinB2 in compressed periodontal tissues during experimental tooth movement. RAW264.7 cells and ST2 cells, used as precursor cells of osteoclasts and osteoblasts, respectively, were subjected to compressive force in vitro. The gene expression of EphB4 and ephrinB2, as well as bone-associated factors including Runx2, Sp7, NFATc1, and calcitonin receptor, were examined by quantitative real-time polymerase chain reaction (PCR). RESULTS: Histological examination of the compression areas of alveolar bone from experimental rats showed that osteoclastogenic activities were promoted while osteogenic activities were inhibited. Immunohistochemistry revealed that ephrinB2 was strongly expressed in osteoclasts in these areas. Quantitative real-time PCR showed that mRNA levels of NFATc1, calcitonin receptor, and ephrinB2 were increased significantly in compressed RAW264.7 cells, and the expression of ephrinB2, EphB4, Sp7, and Runx2 was decreased significantly in compressed ST2 cells. CONCLUSIONS: Our results indicate that compressive force can regulate EphB4 and ephrinB2 expression in osteoblasts and osteoclasts, which might contribute to alveolar bone resorption in compression areas during orthodontic tooth movement.

Data structure representation of 3D reconstruction system of medical images and surface model construction / 生物医学工程学杂志

3D reconstruction from medical images is widely used in diagnose, radiotherapy surgery programming and medical research. This paper deals with the framework and key techniques of 3D reconstruction system of medical images. Methods of automatic and manual segmentation of medical images are designed. Data structure of the system is proposed. The system data are encapsulated in object-oriented paradigm and the hierarchical structure of classes is presented for reconstructing 3D geometry models. The 3D surface geometry model is constructed by using MT algorithm from the tissues extracted by automatic or manual segmentation. An edge collapse algorithm of mesh simplification is proposed and implemented, and the surface model constructed by MT algorithm is simplified by using this algorithm, After reduction of 90 percent triangles, the simplified model still maintains the original feature. It can speed up surface rendering of the models.
