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.

The application of PCR-SSP with the serology in identification and genotyping of ABO ambiguous blood group / 细胞与分子免疫学杂志

Objective To investigate the effect of blood group serology and polymerase chain reaction with sequence-specific primers (PCR-SSP) on identification and genotyping of ambiguous ABO blood group. Methods Eighty suspicious ABO blood group samples were identified by serology and polymerase chain reaction with sequence-specific primers (PCR-SSP). The final blood group type and the strategy of the transfusion of each case were determined according to the results of serology and PCR-SSP. Results 40 cases were confirmed to be subtypes, and the remaining 40 cases were normal types with weakened antigens or missing antibodies due to other reasons. The results of molecular genetic blood group typing based on PCR-SSP were 41 cases of subtypes (There were 3 discrepancies between two methods: one was Ael identified by serological methods, while its gene type was O2O2; one was common type O, while its gene type was BO1; one was type A, while its gene type was AB.) and 39 cases of normal ones. Conclusion Genotyping technology combined with serological typing has an important significance in identification of ABO blood groups.

Resilience Moderated the Predictive Effect of Dual Stigma on Distress Among Chinese Newly Diagnosed HIV-Positive Men Who Have Sex With Men.

Previous studies have examined the distinct stigmas of people living with HIV or of men who have sex with men (MSM). To capture the composite stress of HIV-positive MSM and the mixed stigma they experience, we conceptualized a compound stigma combining HIV status and homosexual identity. At two waves with an interval of 6 months, the results of 112 Chinese newly diagnosed HIV-positive MSM showed that dual stigma at baseline increased distress symptoms 6 months later. Resilience moderated these effects, as the dual stigma increased, distress symptoms intensified more rapidly for individuals with lower resilience than they did for those with higher resilience. Our findings highlight that dual stigma, as an intensified risk factor, predicted distress among the Chinese newly diagnosed HIV-positive MSM, conditioned by the protective factor of resilience. The results have strong implications for developing resilience-based intervention programs in this population.

Age stereotypes, flexible goal adjustment, and well-being among Chinese older adults.

Previous studies have examined the independent roles of positive age stereotypes (PAS) and negative age stereotypes (NAS) in successful aging. This study aimed to examine the joint effect of PAS and NAS on the well-being of Chinese older adults, and to further examine whether this effect was moderated by flexible goal adjustment (FGA). Using a cross-sectional design, 279 Chinese older adults (age range 60‒97 years) completed measures related to age stereotypes, FGA, and well-being. The results showed that PAS interacted with NAS to predict well-being. In addition, the joint effect of PAS and NAS was moderated by FGA. Specially, for older adults with low FGA, NAS weakened the positive association between PAS and well-being; whereas, for older adults with high FGA, NAS could not influence the association between PAS and well-being. Tailored interventions to modify aging perceptions and to enhance coping flexibility competence might be helpful for promoting the well-being of older adults.

Comparative study of 3D facial photography with traditional photography / 实用口腔医学杂志

Objective: To investigate the clinical perspectives of 3dMD photography in orthodontics. Methods: 60 patients with skeletal Ⅰ malocclusion (30 males, 30 females, aged 18 to 35 years) were selected. Facial pictures of them were taken by 3dMD photography and traditional photography respectively, photographing time was recorded. Facial measurements' quality data were analyzed by SPSS 16. 0. Results: The photographing time of the 3dMD group and traditional photographic group was(14. 99 ± 1. 34) s and (45. 33 ± 7. 75) s respectively(P＜ 0. 05); there was no significant difference between the 2 groups in the quality scores. Conclusion: The clinical use of 3dMD in patients can save the operation time and can get similar by the use of results traditional radiography.

Stigma never dies: Mourning a spouse who died of AIDS in China.

Stigma towards people with HIV (PHIV) can affect their family members. In this study of 68 HIV seronegative participants in China whose spouse died of AIDS, 35.3% reported prolonged grief. Stigma beliefs towards PHIV (i.e., belief that PHIV's death leaves the deceased, the family and society better off) predicted grief symptoms. Social campaigns to combat stigma and grief therapy to reconstruct the meaning of HIV-related death may be helpful to reduce suffering in HIV bereaved.

Finite-element investigation on center of resistance of maxillary anterior teeth / 生物医学工程学杂志

A three-dimensional finite element model of premaxillary bone and anterior teeth was established with ANSYS 13.0. The anterior teeth were fixed with strong stainless labial archwire and lingual frame. In the horizontal loading experiments, a horizontal retraction force of 1.5 N was applied bilaterally to the segment through hooks at the same height between 7 and 21 mm from the incisal edge of central incisor; in vertical loading experiments, a vertical intrusion force of 1.5 N was applied at the midline of lingual frame with distance between 4 and 16 mm from the incisal edge of central incisor. After loading, solution was done and displacement and maximum principle stress were calculated. After horizontal loading, lingual displacement and stress in periodontal membrane (PDM) was most homogeneous when the traction force was 14 mm from the edge of central incisor; after vertical loading, intrusive displacement and stress in PDM were most homogeneous when the traction force was 12 mm from the incisal edge of central incisor. The results of this study suggested that the location of center of resistance (CRe) of six maxillary anterior teeth is about 14 mm gingivally and 12 mm lingually to incisal edge of central incisor. The location can provide evidence for theoretical and clinical study in orthodontics.
