These data reveal the pathogenic significance of CD8+ T cells in the development and progression of SS in the salivary glands. Treatment directed against CD8+ T cells may be a rational therapy for the management of SS in human subjects.

Limited research exists on the workplace and personal factors that might be associated with the physical and mental health of nurses working in China. Therefore, the purposes of this study were to examine, in Chinese hospital nurses, the most frequently occurring workplace stressor, the most often used coping strategy, and the relationships that exist among workplace stressors, coping strategies, psychological hardiness, demographic characteristics, and physical and mental health. Four-hundred-and-eighty hospital nurses from five hospitals in three major Chinese cities were administered five self-report questionnaires. The findings indicated the most frequently cited workplace stressor was workload, while the most commonly used coping strategy was positive reappraisal. Numerous positive and negative correlations were found, suggesting the importance that workplace stress, coping strategies, psychological hardiness, and demographic characteristics play in relationship to each other, as well as to both the physical and mental health of Chinese nurses.

BackgroundMenopause is an inevitable stage affecting every middle-aged woman. China has a large and increasing group of post-menopausal women. Most post-menopausal women suffer from increased risks for cardiovascular diseases (CVD) and sleep problems. Previous studies have demonstrated the associations between sleep disorders and increased CVD risks in general population. The current study is to examine the relationship between sleep quality and CVD risks among Chinese post-menopausal women.MethodsThis study was a sub-study nested in a cross-sectional study that investigated the sleep quality of community-dwelling adults in Xian, Shaanxi Province, China. The Chinese version of the Pittsburgh Sleep Quality Index (PSQI) and the Framingham 10-year risk score (FRS) were used to measure sleep quality and CVD risk among 154 Chinese post-menopausal women. Multivariate regression and logistic regression were used to determine the association between sleep quality and CVD risk.ResultsThe participants (age: 63.65 ± 4.47 years) experienced poor sleep quality (mean score of global PSQI = 8.58) and a 10-year risk of CVD of 12.54%. The CVD risk was significantly associated with sleep duration (β = − 0.18, p = 0.04) and sleep disturbance (β = 0.33, p < 0.001). Women with good sleep quality (PSQI ≤5) were less likely to be at high risk for CVD (FRS > 10%) (odds ratio = 0.51, p = 0.04).ConclusionsPoor sleep quality might increase the CVD risk in post-menopausal women. Interventions to promote the cardiovascular health of Chinese post-menopausal women may need to include sleep promotion strategies.

To explore the clinicopathological characteristics and outcomes of light chain deposition disease (LCDD) in a Chinese population, we retrospectively studied the clinicopathological data, treatment, and outcomes of 48 patients with biopsy-proven LCDD from a single center. Among the patients, there were 29 males and 19 females, with an average age of 51 years. The patients presented with hypertension (79.2 %), edema (60.4 %), renal insufficiency (95.8 %), anemia (93.8 %), nephrotic proteinuria (≥3.0 g/24 h) (44.4 %), and hematuria (75.0 %). Moreover, 33.3 % had hypocomplementemia of C3, and 25 % were diagnosed with multiple myeloma. Serum immunofixation electrophoresis and a serum free light chain assay showed that 26.7 and 85.4 % of patients presented with monoclonal immunoglobulin, respectively. Nodular mesangial sclerosis was identified in 83.3 % of our cases and vascular involvement was observed in 77.1 % by light microscopy. Over an average of 22 months of follow-up, the mean renal survival was 32.5 months. Of the patients, 34.1 % had stable or improved renal dysfunction, 2.3 % had worsening renal function, and 63.6 % progressed to end-stage renal disease. Of the 33 patients receiving chemotherapy, 15 patients had stable or improved renal function and the renal survival was higher in patients with hematological and renal responses than in those without. The independent predictors of ESRD by multivariate analysis were serum creatinine (p = 0.008) and urinary retinol binding protein (RBP) (p = 0.045). In conclusion, LCDD was characterized in Chinese patients by renal dysfunction, hypertension, anemia, proteinuria, abnormal free light chain ratios, and less overt hematologic malignancies. Serum creatinine and RBP were independent prognostic factors of LCDD. As better hematologic and renal responses to chemotherapy were associated with improved renal survival, there is an urgent need for multicenter and prospective studies to establish the standardized therapy for LCDD.
