Objective:To explore the potential categories of psychological distress in spousal caregivers of stroke patients and differences in quality of life between categories, in order to provide a theoretical basis for early clinical identification and provision of individualized and targeted interventions for psychological distress in spousal caregivers of stroke patients and improvement of their quality of life.Methods:A total of 207 spouse caregivers of stroke patients hospitalized in three class 1-Grade A hospitals in Yinchuan city of Ningxia Hui Autonomous Region, who met the inclusion and exclusion criteria were selected from December 2020 to July 2021 by convenience sampling method as study subjects. The general information questionnaire, Kessler Psychological Distress Scale, and the Mos 36-Item Short from Health Survey were used for a cross-sectional survey.Results:A total of 203 spousal caregivers of stroke patients were finally investigated, 46 males and 157 females with a age of (58.65 ± 9.66) years. Psychological distress among spousal caregivers of stroke patients was categorized into 3 potential categories:no distress group (40%, 81/203), listlessness group (45%, 91/203) and helplessness and restlessness group (15%, 31/203). The psychological distress subgroup was a factor influencing the quality of life of spousal caregivers of stroke patients ( t=-10.03, P<0.05), explaining 33.0% of the variance in quality of life. Conclusions:Psychological distress in spousal caregivers of stroke patients is significantly heterogeneous. Those in the helplessness and restlessness group have the lowest quality of life and should be given focused attention and early intervention.

Objective:To explore the current situation of resourcefulness among the primary caregivers of stroke patients and analyze its influencing factors.Methods:From December 2020 to August 2021, convenience sampling was used to select 311 primary caregivers of stroke patients in the Neurology Department of three ClassⅢ Grade A general hospitals in Yinchuan City as the research subject. A survey was conducted using the General Information Questionnaire, Resourcefulness Scale, Self-Rating Depression Scale, Chinese Perceived Stress Scale, Social Support Revalued Scale, and the Fatigue Scale-14.Results:A total of 311 questionnaires were distributed and 308 valid questionnaires were collected, with a valid response rate of 99.04%. The resourcefulness score of the primary caregivers of 308 stroke patients was (83.98±12.85). The random forest model showed that when the λ-value was 1.667, the error was the smallest, and the corresponding number of influencing factors was 7. The independent variables ranked in the top 7 in importance were included in multiple stepwise regression. Multiple stepwise regression analysis showed that perceived stress, educational level, and fatigue were the main influencing factors on the resourcefulness of the primary caregivers of stroke patients, and the differences were statistically significant ( P<0.05) . Conclusions:The main caregivers of stroke patients have a moderate level of resourcefulness and require certain attention. Nursing staff can collaborate with social workers and other personnel to provide support and assistance to caregivers, alleviate their physical and mental stress, thereby improving their resourcefulness and the quality of care.

Objective:To investigate effects of the ROCK1 gene on proliferation and migration of and related molecular expression in keloid fibroblasts.Methods:Immunohistochemical technique was used to detect ROCK1 protein expression in human keloids and normal skin tissues, and Western blot analysis was performed to detect the expression of ROCK1, transforming growth factor β1 (TGF-β1) and E-cadherin in keloid tissues. In vitro cultured human keloid fibroblasts (HKFs) were divided into 4 groups: ROCK1 gene overexpression control group (ROCK1 NC group) transfected with ROCK1 gene overexpression control vectors, ROCK1 gene overexpression group (ROCK1 OE group) transfected with ROCK1 gene overexpression vectors, ROCK1 gene knockdown control group (sh NC group) transfected with ROCK1 gene knockdown control vectors, and ROCK1 gene knockdown group (shROCK1 group) transfected with ROCK1 gene knockdown vectors. Cell counting kit-8 (CCK8) assay was performed to evaluate the effect of ROCK1 gene on the survival rate of HKFs, Transwell assay to evaluate the effect on the migration of HKFs, and real-time fluorescence-based quantitative PCR (qRT-PCR) and Western blot analysis were conducted to determine the mRNA and protein expression of ROCK1, TGF-β1 and E-cadherin, respectively. Results:Immunohistochemical study showed that ROCK1 protein expression decreased significantly in the human keloid tissues compared with the normal tissues ( t = 6.47, P = 0.003) ; Western blot analysis showed that the expression levels of ROCK1 and E-cadherin significantly decreased ( t = 14.02, 162.20, respectively, both P < 0.001), while TGF-β1 expression significantly increased ( t = 76.01, P < 0.001) in the keloid tissues compared with the expression levels of corresponding proteins in the normal tissues. CCK8 assay showed that the cell activity was significantly lower in the ROCK1 OE group than in the ROCK1 NC group after 24-hour transfection ( t = 3.25, 3.78, P = 0.031, 0.019, respectively), and significantly higher in the shROCK1 group than in the sh NC group ( t = 3.12, 2.79, P = 0.036, 0.049, respectively). Transwell assay showed that the number of migratory cells was significantly lower in the ROCK1 OE group than in the ROCK1 NC group ( t = 5.17, P = 0.004), and significantly higher in the shROCK1 group than in the sh NC group ( t = 9.28, P < 0.001). Compared with the ROCK1 NC group, the ROCK1 OE group showed significantly increased mRNA and protein expression levels of ROCK1 and E-cadherin ( P < 0.05 or < 0.001), but decreased mRNA and protein expression levels of TGF-β1 (both P < 0.001) ; compared with the sh NC group, the shROCK1 group showed significantly decreased mRNA and protein expression levels of ROCK1 and E-cadherin ( P < 0.05 or < 0.001), but significantly increased mRNA and protein expression levels of TGF-β1 ( P = 0.005 or < 0.001) . Conclusions:The ROCK1 gene can inhibit the proliferation and migration of HKFs. Overexpression of the ROCK1 gene can down-regulate the TGF-β1 gene expression and up-regulate the E-cadherin gene expression in HKFs.

Objective:To explore the relationship between psychological distress and intimacy in stroke patients and the mediating effect of different dyadic coping style, to provide theoretical guidance for improving the intimate relationship of stroke patients.Methods:A convenient sampling method was used to select 203 patients with stroke who visited the General Hospital of Ningxia Medical University, the People's Hospital of Ningxia Hui Autonomous Region and the Department of Neurology of Yinchuan First People's Hospital from December 2020 to July 2021 as the survey objects. The general information questionnaire, Kessler Psychological Distress Scale, Quality of Relationship Index and Dyadic Coping Inventory were used to investigate patients.Results:The scores of psychological distress, intimate relationship, positive dyadic coping and negative dyadic coping were 19.33 ± 7.46, 32.75 ± 6.79, 86.25 ± 13.22, and 16.46 ± 4.08, respectively. Correlation analysis showed that psychological distress was negatively correlated with intimate relationship and positive dyadic coping ( r=-0.195, -0.204, both P<0.01), psychological distress was positively correlated with negative dyadic coping ( r=0.229, P<0.01). The mediating effect of positive dyadic coping and negative dyadic coping on psychological distress and intimate relationship was 35.87% and 53.26%, respectively. Conclusions:The psychological distress indirectly affects the intimate relationship of stroke patients through positive dyadic coping and negative dyadic coping. Health care workers can guide patients to actively cope with the disease and encourage couples to strengthen communication, so as to enhance the intimacy of couples and promote their physical and mental health development.

Objective:To explore the potential categories of resourcefulness in primary caregivers of stroke patients and analyze the differences in the characteristics of different types of caregivers, so as to provide basis for clinical construction of effective intervention plans.Methods:The 308 primary caregivers of stroke patients who met the research standards in the Department of Neurology of General Hospital of Ningxia Medical University, People′s Hospital of Ningxia Hui Autonomous Region, the First People′s Hospital of Yinchuan from December 2020 to August 2021 were selected as the research objects by convenient sampling method.The general information questionnaire, Resourcefulness Scale and Social Support Revalued Scale were used for cross-sectional investigation.Results:The resourcefulness of the primary caregivers of stroke patients were divided into 2 potential categories: low resourcefulness group (62.7%, 193/308) and high resourcefulness group (37.3%, 115/308). Uni-variate analysis showed that there were differences between potential categories: age and education level of stroke patients, whether there was long-term medication history, number of other chronic diseases, had there been any complications due to illness, age, education level and occupation of caregivers, average daily care duration, family relations, and social support ( χ2 values were -3.34 - 23.62, all P<0.05). Logistic regression analysis showed that social support and education level of caregivers were the influencing factors of caregiver resourcefulness ( P<0.05). Conclusions:The resourcefulness in the primary caregivers of stroke patients has certain characteristics. Clinically, targeted intervention measures should be formulated according to the different types of caregiver resourcefulness characteristics of caregivers and their influencing factors to improve the caregiver resourcefulness of stroke patients.

Objective:To construct a conceptual framework of burnout among primary caregivers of stroke patients based on grounded theory.Methods:According to the characteristics of age, gender, relationship with patients, length of care and other characteristics of purpose sampling method, from December 2021 to March 2022, 31 primary caregivers of stroke patients were selected for semi-structured interviews in two second-class hospitals, a first-class hospitals and a community health service station in Wuzhong city and Yinchuan city. The data were analyzed in procedural grounded theory method.Results:A total of 29 primary categories and 9 secondary categories were formed. The conceptual framework of burnout among primary caregivers of stroke patients was finally established, which consisted of four main categories (role burnout, physical burnout, psychological burnout and social burnout) and a core category (burnout of primary caregivers of stroke patients).Conclusions:The conceptual framework of burnout among primary caregivers of stroke patients constructed in this study elaborates the connotation of burnout of primary caregivers of stroke patients from four aspects, which can provide a basis for the development of assessment tools and the formulation of intervention measures in the future.

Objective:To explore the effect of perceived stress on fatigue and its mechanism, so as to provide theoretical support for relieving the fatigue of the main caregivers of stroke patients.Methods:From December 2020 to August 2021, 311 main caregivers of stroke patients hospitalized in the Department of Neurology of Class Ⅲ Grade A hospitals in Yinchuan were selected by convenient sampling. The caregivers were investigated with the General Information Questionnaire, Perceived Stress Scale, Resourcefulness Scale, Social Support Rating Scale and Fatigue Scale.Results:In this study, a total of 311 questionnaires were distributed, and 308 valid questionnaires were recovered, with an effective recovery rate of 99.04%. The total scores of perceived stress, fatigue, resourcefulness and social support of the main caregivers of stroke patients were (24.98±6.36) , (5.31±2.86) , (83.98±12.85) and (39.76±6.21) respectively. Perceived stress were negatively correlated with resourcefulness and social support ( r=-0.313, -0.274, P<0.01) , and positively correlated with fatigue ( r=0.261, P<0.01) . Fatigue were negatively correlated with resourcefulness and social support ( r=-0.305, -0.268; P<0.01) . There was a positive correlation between resourcefulness and social support ( r=0.210, P<0.01) . The results of intermediary test showed that the direct effect of perceived stress on fatigue was valid, and the respective intermediary effect of resourcefulness and social support between perceived stress and fatigue, and the chain intermediary effect of resourcefulness and social support were also valid, with the amount of intermediary effect being 26.92%, 15.38% and 3.85% respectively. Conclusions:The chain mediation between perceived stress and fatigue is established between the resourcefulness and social support of the main caregivers of stroke patients. In the future, the mental and physical pressure of stroke patients can be alleviated by improving the resourcefulness of their main caregivers and providing social support.

Objective:To understand the mediating role of resourcefulness between perceived stress and depression in primary caregivers of stroke patients.Methods:The primary caregivers of 311 inpatients with stroke in three Class Ⅲ Grade A hospitals in Yinchuan from December 2020 to August 2021 were selected by convenience sampling and investigated with the general information form, Resourcefulness Scale (RS) , Chinese Perceived Stress Scale (CPSS) and Self-Rating Depression Scale (SDS) . SPSS 25.0 and PROCESS were used to analyze the relationship between the three, and to explore the mediating role of resourcefulness between perceived stress and depression in the primary caregivers of stroke patients.Results:In this study, 311 questionnaires were distributed, 311 questionnaires were recovered, and 308 questionnaires were valid. The primary caregivers of stroke patients scored (24.98±6.38) for perceived stress, (83.98±12.85) for resourcefulness, and (44.35±8.40) for depression. Resourcefulness was negatively correlated with perceived stress and depression scores ( r=-0.313, -0.317; P <0.01) , and perceived stress was positively correlated with depression ( r=0.425, P<0.01) . The Bootstrap method further validated that resourcefulness played a partial mediating role between perceived stress and depression, and the mediating effect accounted for 14.95% of the total effect. Conclusions:Resourcefulness is a mediating variable between the perceived stress and depression of the primary caregivers of stroke patients, and resourcefulness plays a partial mediating role between perceived stress and depression.

Objective:To investigate the clinicopathological features, immunophenotype and differential diagnosis of clear cell hidradenoma, and to analyze the origin of clear cell hidradenoma and the underlying mechanism.Methods:The clinical data of 23 cases of clear cell hidradenoma who underwent surgical resection in Suzhou Municipal Hospital between December 2017 and July 2021 were retrospectively analyzed. Clinical manifestation, imaging features, pathological features and prognosis of the 23 cases of clear cell hidradenoma were analyzed. Expression levels of epithelial membrane antigen, cytokeratin 20, cytokeratin 7, cytokeratin 14, carcinoembryonic antigen, and gross cystic disease fluid protein 15 were detected by immunohistochemical staining technique using the EnVision system. Periodic acid-Schiff (PAS) staining was performed to visualize glycogen.Results:Among the 23 cases, 8 were male and 14 were female, aged 14-94 years, with a median age of 55 years. The first symptom of clear cell hidradenoma was epidermal bulgels in 18 cases.Contrast ultrasonography showed a subcutaneous cystic solid echo mass with abundant blood flow in the solid part. The tumor histologically consisted of two types of cells: secretory epithelial cells or glandular epithelial cells and clear cells. Twenty cases had tumors with the features of benign clear cell hidradenoma. Two cases had atypical clear cell hidradenoma with atypia and mitosis. One case had malignant clear cell hidradenoma. Tumor cells were positive for epithelial membrane antigen, cytokeratin 7, cytokeratin 14, carcinoembryonic antigen, and gross cystic disease fluid protein 15 and they were Periodic acid-Schiff-positive. Twenty-three patients were followed up for 2-36 months, of which 4 were lost to follow-up and the rest had no recurrence of clear cell hidradenoma.Conclusion:Clear cell hidradenoma is rare and has a good prognosis. Malignant clear cell hidradenoma is rarer and has a poor prognosis. Diagnosis of clear cell hidradenoma is mainly based on comprehensive analysis of pathological features and immunophenotypes. Clear cell hidradenoma should be differentiated from metastatic clear cell carcinoma, spiral adenoma, cortical adenoma, and malignant melanoma.
