Background Depressive moods among occupational population are prevalent, which seriously affect their mental-physical health and socioeconomic productivity. This has become an urgent public health concern. Objective To understand current situation of depressive mood among an occupational population aged 18 to 60 covering 120 cities of China, and to explore the relationship between work-family conflict and depressive mood as well as the role of life stress in the relationship, as to provide a scientific basis for developing measures to reduce depressive mood in the occupational population. Methods Using the data of the Psychology and Behavior Investigation of Chinese Residents in 2021, an occupational population aged 18 to 60 years was selected as study subjects. A total of 3785 subjects were included in the study. The Work-Family Conflict Scale, Subjective Life Stress Scale, and Patient Health Questionnaire-Depression Scale were used to assess the work-family conflict, life stress, and depressive mood of the subjects. Harman's single-factor method was used to evaluate common method bias in the survey data. One-way ANOVA was applied to test the difference in work-family conflict, life stress, and depressive mood among occupational population by demographic characteristics, and chi-square test was used to analyze the difference in reporting depressive mood. Partial correlation analysis was used to evaluate the correlation between selected variables. Process plug-in was used to test potential mediating effect of life stress on work-family conflict and depressive emotion. Results The scores of work-family conflict, life stress, and depressive mood among the occupational population were 24.60±8.28, 9.28±3.78, and 5.43±5.30, respectively. The prevalence rates of depressive mood was 48.7% (1888/3875). The score of depressive mood among occupational population who never smoked was significantly higher than that of those who smoked (P<0.01). The partial correlation analysis showed that work-family conflict and life stress were positively correlated with depressive mood (r=0.472 and 0.447, P<0.001); work-family conflict was positively correlated with life stress (r=0.361, P<0.001). The mediation analysis results showed that work-family conflict positively associated with life stress (b=0.361, P<0.001); life stress positively associated with depressive mood (b=0.318, P<0.001); work-family conflict positively associated with depressive mood (b=0.357, P<0.001), and played a partial mediating role in the relationship between work-family conflict and depressive mood with an effect size of 0.115 (95%CI: 0.099, 0.130) that accounted for 24.36% of the total effect. Conclusion Work-family conflict may not only directly affect depressive mood among occupational population, but also indirectly affect depressive mood through a mediating effect of life stress.

Objective:This study aimed to determine the value of bone marrow biopsy (BMB) , bone marrow aspiration (BMA) , and positron emission tomography combined with computed tomography (PET/CT) in bone marrow (BM) involvement and prognosis evaluation in diffuse large B-cell lymphoma (DLBCL) .Methods:The clinical data of patients with DLBCL who underwent PET/CT, BMB, and BMA of the iliac crest were retrospectively analyzed in Peking Union Medical College Hospital from January 2015 to November 2017. The BM involvement on PET/CT was defined as the ratio of maximal standardized uptake values of iliac crest BM to liver parenchyma intensity ≥1.Results:A total of 76 patients without liver involvement were enrolled, there were 32 males, and the median age was 53 (17-79) . Moreover, 16 patients (21.1%) had BM involvement on PET/CT, 12 (15.8%) had positive BMB, and 13 (17.1%) had positive BMA. Excellent correlation between BMA and BMB ( κ=0.943) was found, including good correlation between PET/CT and BMB/BMA ( κ=0.763 and 0.776, respectively) . After a median follow-up of 52 (0-82) months, BM involvement by BMB ( P=0.037) and BMA ( P=0.007) were poor prognostic factors for overall survival, positive PET/CT had no significant effect on prognosis ( P>0.05) . Conclusion:PET/CT, BMB, and BMA are effective methods to detect BM involvement with great concordance. However, iliac crest BMB and BMA showed superior performance in prognosis evaluation.

Objective:To investigate the expressions of CD200 and inducible costimulator (ICOS) protein in angioimmunoblastic T-cell lymphoma (AITL) and the relationship with prognosis as well as their significances in the differential diagnosis of AITL.Methods:A total of 39 AITL patients in the First People's Hospital of Chenzhou, the Fourth People's Hospital of Chenzhou, Xiangnan College Affiliated Hospital and Chenzhou 3rd People's Hospital from June 2012 to December 2019, and 10 patients with classic Hodgkin lymphoma (CHL) and 10 patients with peripheral T cell lymphoma, not otherwise specified (PTCL-NOS) from August 2016 to July 2019 in the First People's Hospital of Chenzhou were selected. Immunohistochemistry was used to detect the expressions of CD200, ICOS, CD10, programmed death 1 (PD-1), bcl-6 and CXC chemokine receptor-13 (CXCL13) proteins, and the correlation of CD200 and ICOS with clinicopathological features and prognosis of AITL patients was analyzed, and the diagnostic significance of both in differentiating AITL from PTCL-NOS and CHL was also analyzed.Results:The positive rates of CD200 and ICOS in 39 AITL patients were 71.79% (28/39) and 61.54% (24/39), respectively. There were 7 cases of CD200 weak and moderate positive in 10 CHL patients, and ICOS proteins were all negative. Among 10 PTCL-NOS patients, 4 patients had CD200 positive and 1 patient had ICOS positive. The differences in positive rates of ICOS protein between AITL patients and CHL, PTCL-NOS patients were statistically significant (all P < 0.05); the differences in positive rates of CD200 protein between AITL patients and CHL, PTCL-NOS patients were not statistically significant ( χ2=0.013, P=0.911; χ2=3.551, P=0.060). The positive rate of CD200 in AITL patients with elevated lactate dehydrogenase (LDH) and international prognostic index (IPI) score of 3-4 was higher than that in AITL patients with normal LDH and IPI score of 0-2 (both P < 0.05); The positive rate of ICOS in AITL patients with elevated LDH and PD-1 positive was higher than that in AITL patients with normal LDH and PD-1 negative (both P < 0.05). CD200 negative AITL patients had better 3-year overall survival (OS) rate (4.2% vs. 66.7%) and 3-year progression-free survival (PFS) rate (5.3% vs. 77.1%) compared with those in CD200 positive AITL patients, and the differences between both groups were statistically significant (both P < 0.01); there was a statistically significant difference in 3-year OS rate between ICOS positive AITL patients and ICOS negative AITL patients (15.3% vs. 38.6%, P=0.011), while there was no statistically significant difference in 3-year PFS rate of both groups (18.6% vs. 41.5%, P=0.059). Multivariate analysis showed CD200 ( HR=0.076, 95% CI 1.555-79.497, P=0.001), extranodal involvement or not ( HR=11.117, 95% CI 1.555-79.497, P=0.016) and LDH ( HR=2.147, 95% CI 0.844-5.459, P=0.109) were independent influencing factors of OS in AITL patients; CD200 ( HR=0.075, 95% CI 0.016-0.357, P=0.001) and LDH ( HR=2.335, 95% CI 0.929-5.870, P=0.071) were independent influencing factors of PFS in AITL patients. Conclusions:CD200 and ICOS can be used as immunohistochemical indicators to assist the diagnosis of AITL patients. ICOS protein helps to differentiate AITL from CHL and PTCL-NOS; CD200 can be used as indicators to judge the prognosis and deterioration of AITL patients.

Objective:To correlate homocysteine (Hcy) and blood lipid levels with neurological function in patients with progressive ischemic stroke.Methods:A total of 400 patients with ischemic stroke who received treatment between June 2018 and June 2020 in Linhai Second People's Hospital were included in this study. Progressive ischemic stroke ( n = 126) and non-progressive ischemic stroke ( n = 274) groups were designated. Hcy level was determined by enzyme-linked immunosorbent assay. High-density lipoprotein cholesterol, triacylglycerol, low-density lipoprotein cholesterol and cholesterol levels were measured using a biochemical analyzer. Hcy and blood lipid levels as well as National Institute Health of Stroke Scale (NIHSS) score were determined in each group. Hcy and blood lipid levels were correlated with NIHSS score. Results:Hcy level in the progressive ischemic stroke group was significantly higher than that in the non-progressive ischemic stroke group [(28.39 ± 4.36) μmol/L vs. (20.17 ± 3.24) μmol/L, t = 18.894, P < 0.05]. Low-density lipoprotein cholesterol , triacylglycerol and TC levels in the progressive ischemic stroke group were (3.29 ± 0.45) mmol/L, (2.08 ± 0.34) mmol/L and (4.82 ± 0.79) mmol/L, respectively, which were significantly higher than those in the non-progressive ischemic stroke group [(2.48 ± 0.37) mmol/L, (1.56 ± 0.29) mmol/L and (4.08 ± 0.43) mmol/L, t = 17.644, 14.859, 9.860, P < 0.05]. High-density lipoprotein cholesterol level in the progressive ischemic stroke group was significantly lower than that in the non-progressive ischemic stroke group [(1.03 ± 0.13) mmol/L vs. (1.19 ± 0.14) mmol/L, t =11.158, P < 0.05]. NIHSS score in the progressive ischemic stroke group was significantly higher than that in the non-progressive ischemic stroke group [(21.72 ± 4.35) points vs. (15.52 ± 2.89) points, t = 14.582, P < 0.05]. Hcy, low-density lipoprotein cholesterol, cholesterol and triacylglycerol levels were linearly and positively correlated with NIHSS score ( r = 0.846, 0.724, 0.718, 0.765, all P < 0.05), while igh-density lipoprotein cholesterol level was linearly and negatively correlated with NIHSS score ( r = -0.710, P < 0.05). Conclusion:In patients with progressive ischemic stroke, Hcy level is increased and blood lipid level is obviously abnormal. Hcy and blood lipid levels are greatly correlated with neurological function.
